A novel microgrid demand-side management system for manufacturing facilities

NASA Astrophysics Data System (ADS)

Harper, Terance J.

Thirty-one percent of annual energy consumption in the United States occurs within the industrial sector, where manufacturing processes account for the largest amount of energy consumption and carbon emissions. For this reason, energy efficiency in manufacturing facilities is increasingly important for reducing operating costs and improving profits. Using microgrids to generate local sustainable power should reduce energy consumption from the main utility grid along with energy costs and carbon emissions. Also, microgrids have the potential to serve as reliable energy generators in international locations where the utility grid is often unstable. For this research, a manufacturing process that had approximately 20 kW of peak demand was matched with a solar photovoltaic array that had a peak output of approximately 3 KW. An innovative Demand-Side Management (DSM) strategy was developed to manage the process loads as part of this smart microgrid system. The DSM algorithm managed the intermittent nature of the microgrid and the instantaneous demand of the manufacturing process. The control algorithm required three input signals; one from the microgrid indicating the availability of renewable energy, another from the manufacturing process indicating energy use as a percent of peak production, and historical data for renewable sources and facility demand. Based on these inputs the algorithm had three modes of operation: normal (business as usual), curtailment (shutting off non-critical loads), and energy storage. The results show that a real-time management of a manufacturing process with a microgrid will reduce electrical consumption and peak demand. The renewable energy system for this research was rated to provide up to 13% of the total manufacturing capacity. With actively managing the process loads with the DSM program alone, electrical consumption from the utility grid was reduced by 17% on average. An additional 24% reduction was accomplished when the microgrid and DSM program was enabled together, resulting in a total reduction of 37%. On average, peak demand was reduced by 6%, but due to the intermittency of the renewable source and the billing structure for peak demand, only a 1% reduction was obtained. During a billing period, it only takes one day when solar irradiance is poor to affect the demand reduction capabilities. To achieve further demand reduction, energy storage should be introduced and integrated.

Air pollution effects due to deregulation of the electric industry

NASA Astrophysics Data System (ADS)

Davoodi, Khojasteh Riaz

The Energy Policy Act of 1992 introduced the concept of open-access into the electric utility industry which allows privately-owned utilities to transmit power produced by non-utility generators and independent power producers (IPPs). In April 1996, the Federal Energy Regulatory Commission (FERC) laid down the final rules (Orders No. 888 & No. 889), which required utilities to open their transmission lines to any power producer and charge them no more than what they pay for the use of their own lines. These rules set the stage for the retail sale of electricity to industrial, commercial and residential utility customers; non-utility generators (Nugs); and power marketers. These statutory, regulatory and administrative changes create for the electric utility industry two different forces that contradict each other. The first is the concept of competition among utility companies; this places a greater emphasis on electric power generation cost control and affects generation/fuel mix selection and demand side management (DSM) activities. The second force, which is converse to the first, is that utilities are major contributors to the air pollution burden in the United States and environmental concerns are forcing them to reduce emissions of air pollutants by using more environmentally friendly fuels and implementing energy saving programs. This study evaluates the impact of deregulation within the investor owned electric utilities and how this deregulation effects air quality by investigating the trend in demand side management programs and generation/fuel mix. A survey was conducted of investor owned utilities and independent power producers. The results of the survey were analyzed by analysis of variance and regression analysis to determine the impact to Air Pollution. An air Quality Impact model was also developed in this study. This model consists of six modules: (1) demand side management and (2) consumption of coal, (3) gas, (4) renewable, (5) oil and (6) nuclear sources until the year 2005. Each module was analyzed separately and the result from each module was transferred into the Air Quality Impact model. The model assesses the changes in electricity generation within each module due to deregulation and these changes can then be correlated to the emission of air pollutants in the United States.

National Conference on Integrated Resource Planning: Proceedings

NASA Astrophysics Data System (ADS)

Until recently, state regulators have focused most of their attention on the development of least-cost or integrated resource planning (IRP) processes for electric utilities. A number of commissions are beginning to scrutinize the planning processes of local gas distribution companies (LDCs) because of the increased control that LDCs have over their purchased gas costs (as well as the associated risks) and because of questions surrounding the role and potential of gas end-use efficiency options. Traditionally, resource planning (LDCs) has concentrated on options for purchasing and storing gas. Integrated resource planning involves the creation of a process in which supply-side and demand-side options are integrated to create a resource mix that reliably satisfies customers' short-term and long-term energy service needs at the lowest cost. As applied to gas utilities, an integrated resource plan seeks to balance cost and reliability, and should not be interpreted simply as the search for lowest commodity costs. The National Association of Regulatory Utility Commissioners' (NARUC) Energy Conservation committee asked Lawrence Berkeley Laboratory (LBL) to survey state PUCs to determine the extent to which they have undertaken least cost planning for gas utilities. The survey included the following topics: status of state PUC least-cost planning regulations and practices for gas utilities; type and scope of natural gas DSM programs in effect, including fuel substitution; economic tests and analysis methods used to evaluate DSM programs; relationship between prudency reviews of gas utility purchasing practices and integrated resource planning; and key regulatory issues facing gas utilities during the next five years.

Any electrical utility prefers to implement demand side management and change the shape of the demand curve in a beneficial manner. This paper aims to assess the financial gains (or losses) to the generating sector through the implementation of demand side management programs. An optimization algorithm is developed to find the optimal generation mix that minimizes the daily total generating cost. This daily total generating cost includes the daily generating cost as well as the environmental damage cost. The proposed optimization algorithm is used to find the daily total generating cost for the base case and for several demand side management programs using the data obtained from the Sri Lankan power system. Results obtained for DSM programs are compared with the results obtained for the base case to assess the financial benefits of demand side management to the generating sector.

Managing Residential Electricity Demand Through Provision of Better Feedback

NASA Astrophysics Data System (ADS)

Collins, Myles

New and affordable technology for providing detailed feedback on household electricity usage presents a host of opportunities for utilities and policy-makers to manage demand. This dissertation examines ways to use these devices to reduce - and shift the timing of - energy use in the residential sector by influencing consumers' behavior. The first portion of the study analyzes the impact of programmable thermostats (PTs) on energy use, focusing on residents' knowledge of climate control settings in the dwelling. I found that of households with natural gas heating systems, young households with PTs used 17 percent less heating energy on average. In addition, residents who did not know their thermostat settings tended to use 10 percent more energy for heating. The main portion of the dissertation focuses specifically on the potential for better feedback on electricity usage to reduce household energy consumption. The existing literature suggests that feedback can reduce electricity consumption in homes by 5 to 20 percent, but that significant uncertainties remain in our knowledge of the effectiveness of feedback. These uncertainties include the variation in feedback effectiveness between demographic groups and consumers in different climate regions. This analysis uses these uncertainties to perform an exploratory analysis to determine the conditions under which the benefits of feedback outweigh the costs and to compare the cost-effectiveness of providing feedback against that of other DSM programs. I found that benefits would likely outweigh costs for enhanced monthly billing and real-time feedback and that cost-effectiveness was superior to that of other DSM programs for these types of feedback. For feedback that is disaggregated by appliance type, cost effectiveness was competitive with other DSM programs under a limited set of cases. This study also examines how energy consumption devices should display feedback on GHG emissions from electricity use under a real-time pricing program. I found that load-shifting can cause GHG emissions to increase or decrease depending on region and season and in no discernable pattern. Therefore, feedback may be more useful and comprehensible to households in the form of total GHG emissions attributable to electricity usage instead of the emission rate of the marginal power plant. Finally, this dissertation explores ways to maximize the effect of feedback by evaluating which appliances may be best suited for appliance-specific feedback. Due to the energy use and behavioral factors associated with each appliance, the most promising appliances were those that heat water for taps, showers, hot tubs, and waterbeds.

Billingsley, Megan A.; Hoffman, Ian M.; Stuart, Elizabeth

End-use energy efficiency is increasingly being relied upon as a resource for meeting electricity and natural gas utility system needs within the United States. There is a direct connection between the maturation of energy efficiency as a resource and the need for consistent, high-quality data and reporting of efficiency program costs and impacts. To support this effort, LBNL initiated the Cost of Saved Energy Project (CSE Project) and created a Demand-Side Management (DSM) Program Impacts Database to provide a resource for policy makers, regulators, and the efficiency industry as a whole. This study is the first technical report of themore » LBNL CSE Project and provides an overview of the project scope, approach, and initial findings, including: • Providing a proof of concept that the program-level cost and savings data can be collected, organized, and analyzed in a systematic fashion; • Presenting initial program, sector, and portfolio level results for the program administrator CSE for a recent time period (2009-2011); and • Encouraging state and regional entities to establish common reporting definitions and formats that would make the collection and comparison of CSE data more reliable. The LBNL DSM Program Impacts Database includes the program results reported to state regulators by more than 100 program administrators in 31 states, primarily for the years 2009–2011. In total, we have compiled cost and energy savings data on more than 1,700 programs over one or more program-years for a total of more than 4,000 program-years’ worth of data, providing a rich dataset for analyses. We use the information to report costs-per-unit of electricity and natural gas savings for utility customer-funded, end-use energy efficiency programs. The program administrator CSE values are presented at national, state, and regional levels by market sector (e.g., commercial, industrial, residential) and by program type (e.g., residential whole home programs, commercial new construction, commercial/industrial custom rebate programs). In this report, the focus is on gross energy savings and the costs borne by the program administrator—including administration, payments to implementation contractors, marketing, incentives to program participants (end users) and both midstream and upstream trade allies, and evaluation costs. We collected data on net savings and costs incurred by program participants. However, there were insufficient data on participant cost contributions, and uncertainty and variability in the ways in which net savings were reported and defined across states (and program administrators).« less

To evaluate the impacts of the chronic disease management program on the outcomes and cost of care for Virginia Medicaid beneficiaries. A total of 35,628 patients and their physicians and pharmacists received interventions for five chronic diseases and comorbidities from 1999 to 2001. Comparisons of medical utilization and clinical outcomes between experimental groups and control group were conducted using ANOVA and ANCOVA analyses. Findings indicate that the disease state management (DSM) program statistically significantly improved patient's drug compliance and quality of life while reducing (ER), hospital, and physician office visits and adverse events. The average cost per hospitalization would have been $42 higher without the interventions. A coordinated disease management program designed for Medicaid patients experiencing significant chronic diseases can substantially improve clinical outcomes and reduce unnecessary medical utilization, while lowering costs, although these results were not observed across all disease groups. The DSM model may be potentially useful for Medicaid programs in states or other countries. If the adoption of the DSM model is to be promoted, evidence of its effectiveness should be tested in broader settings and best practice standards are expected.

A framework for improving the cost-effectiveness of DSM program evaluations

DOE Office of Scientific and Technical Information (OSTI.GOV)

Sonnenblick, R.; Eto, J.

The prudence of utility demand-side management (DSM) investments hinges on their performance, yet evaluating performance is complicated because the energy saved by DSM programs can never be observed directly but only inferred. This study frames and begins to answer the following questions: (1) how well do current evaluation methods perform in improving confidence in the measurement of energy savings produced by DSM programs; (2) in view of this performance, how can limited evaluation resources be best allocated to maximize the value of the information they provide? The authors review three major classes of methods for estimating annual energy savings: trackingmore » database (sometimes called engineering estimates), end-use metering, and billing analysis and examine them in light of the uncertainties in current estimates of DSM program measure lifetimes. The authors assess the accuracy and precision of each method and construct trade-off curves to examine the costs of increases in accuracy or precision. Several approaches for improving evaluations for the purpose of assessing program cost effectiveness are demonstrated. The methods can be easily generalized to other evaluation objectives, such as shared savings incentive payments.« less

The Childhood Autism Rating Scale, Second Edition (CARS2; 2010) includes two rating scales; the CARS2-Standard Version (CARS2-ST) and the newly developed CARS2-High Functioning Version (CARS2-HF). To assess the diagnostic agreement between the CARS2 and DSM-IV-TR versus DSM-5 criteria for Autism Spectrum Disorder (ASD), clinicians at community based centers of the University of North Carolina TEACCH Autism Program rated participants seen for a diagnostic evaluation on symptoms of autism using both the DSM-IV-TR and DSM-5 criteria and either the CARS2-HF or the CARS2-ST. Findings suggest that overall, the diagnostic agreement of the CARS2 remains high across DSM-IV and DSM-5 criteria for autism.

In this paper we review the Diagnostic and Statistical Manual of mental health (DSM), its scientific bases and utility. The concepts of “normality,” “pathology,” and boundaries between them are critically reviewed. We further use the concepts of mindfulness and mindlessness, and evidence from cognitive and social sciences to investigate the DSM clinical and social impact and we argue against its assigned overpower. We recommend including alternative perspectives to the DSM, such as mindfulness and positive psychology. We also argue for including mindfulness training in psychiatric residency and clinical psychology programs. PMID:24987385

An Economic Evalution of Demand-side Energy Storage Systems by using a Multi-agent based Electricity Market

NASA Astrophysics Data System (ADS)

Furusawa, Ken; Sugihara, Hideharu; Tsuji, Kiichiro

Opened wholesale electric power market in April 2005, deregulation of electric power industry in Japan has faced a new competitive environment. In the new environment, Independent Power Producer (: IPP), Power Producer and Supplier (: PPS), Load Service Entity (: LSE) and electric utility can trade electric energy through both bilateral contracts and single-price auction at the electricity market. In general, the market clearing price (: MCP) is largely changed by amount of total load demand in the market. The influence may cause price spike, and consequently the volatility of MCP will make LSEs and their customers to face a risk of revenue and cost. DSM is attracted as a means of load leveling, and has effect on decreasing MCP at peak load period. Introducing Energy Storage systems (: ES) is one of DSM in order to change demand profile at customer-side. In case that customers decrease their own demand at jumped MCP, a bidding strategy of generating companies may be changed their strategy. As a result, MCP is changed through such complex mechanism. In this paper the authors evaluate MCP by multi-agent. It is considered that customer-side ES has an effect on MCP fluctuation. Through numerical examples, this paper evaluates the influence on MCP by controlling customer-side ES corresponding to variation of MCP.

New innovations and technologies using unmanned aerial systems (UAS), or drones, have created unique opportunities for commercial applications. Electric utilities, likewise, realize the benefits of using UAS as a tool in electric utility operations. Although the opportunities exist, establishing a UAS program for electric utilities is largely an endeavor of trial and error or research and development with no clear path defined on how to establish a UAS program. By reviewing UAS use case examples and integrating lessons learned with Federal Aviation Administration (FAA) regulations, UAS best practices, unique electric utility values, legal and insurance perspectives, equipment selection, and thoughtful planning and preparation; a solution model is developed to establish a UAS program for electric utilities.

This study evaluated the relative distribution and inter-rater reliability of revised DSM-5 criteria for eating disorders in a residential treatment program. Consecutive adolescent and young adult females (N=150) admitted to a residential eating disorder treatment facility were assigned both DSM-IV and DSM-5 diagnoses by a clinician (n=14) via routine clinical interview and a research assessor (n=4) via structured interview. We compared the frequency of diagnostic assignments under each taxonomy and by type of assessor. We evaluated concordance between clinician and researcher assignment through inter-rater reliability kappa and percent agreement. Significantly fewer patients received either clinician or researcher diagnoses of a residual eating disorder under DSM-5 (clinician-12.0%; researcher-31.3%) versus DSM-IV (clinician-28.7%; researcher-59.3%), with the majority of reassigned DSM-IV residual cases reclassified as DSM-5 anorexia nervosa. Researcher and clinician diagnoses showed moderate inter-rater reliability under DSM-IV (κ=.48) and DSM-5 (κ=.57), though agreement for specific DSM-5 other specified feeding or eating disorder (OSFED) presentations was poor (κ=.05). DSM-5 revisions were associated with significantly less frequent residual eating disorder diagnoses, but not with reduced inter-rater reliability. Findings support specific dimensions of clinical utility for revised DSM-5 criteria for eating disorders. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

The Shifting Landscape of Ratepayer-Funded Energy Efficiency in the U.S.

DOE Office of Scientific and Technical Information (OSTI.GOV)

Barbose, Galen L; Goldman, Charles; Schlegel, Jeff

Over the last two decades, utility ratepayer funding for energy efficiency programs - and the associated energy savings - has seen both booms and busts. Currently, about 35 states implement ratepayer-funded energy efficiency programs, with a total U.S. budget of $3.1 billion in 2008, approximately 80% of which is concentrated in just ten states (CEE 2008).2 However, a proliferation of new state-level policies enacted over the past several years suggests that the next decade may see a dramatic and sustained increase in overall funding levels, and a fundamental re-drawing of the energy efficiency map. These new state energy efficiency policiesmore » reflect a variety of concerns, including the increasing cost and siting challenges of building new generation and transmission, fuel cost and supply risks, and the potential cost of future carbon regulations. Within the past three years, for example, eleven states have adopted energy efficiency portfolio (or resource) standards (EEPS or EERS) that establish specific long-term savings targets that utilities are obligated to meet, and at least three other states are currently considering the same. A growing number of states have recently established laws requiring utilities to acquire all available cost-effective energy efficiency. Regulators in several Western states have also recently revised integrated resource planning (IRP) and demand-side management (DSM) planning rules to require more robust analysis of the resource potential and benefits of energy efficiency, which has resulted in increased savings targets for their energy efficiency portfolios (Hopper et al. 2008). Finally, regulators and utilities in many states are beginning to look more closely at regulatory incentive mechanisms to better align utility financial interests with improvements in customer energy efficiency. We examined energy efficiency policies on the books or in the pipeline in all 50 states, along with recent IRPs and DSM plans, and developed low, medium and high projections of future energy efficiency spending and savings. Depending on how aggressively and effectively states implement these policies, we estimate that spending on ratepayer-funded energy efficiency could increase from $3.1 billion in 2008 to more than $12 billion (nominal dollars) per year by 2020 in our high case, a growth rate in spending of about 12% per year. Annual electricity savings nationally could triple from an estimated 0.3% of retail electricity sales in 2008 to 0.9% of retail electricity sales in 2020. In the low and medium scenarios, ratepayer funding for electric and gas energy efficiency in the U.S. would increase to $5.4 and $7.5 billion, respectively, by 2020. What are the implications of such a scale-up of ratepayer-funded energy efficiency activity for national energy policy, such as a national EEPS or future carbon regulations? Can a ramp-up of this scale be achieved, and what practical constraints might slow these efforts? This paper addresses these questions by first providing an overview of recent trends in state policies pertaining to ratepayer-funded energy efficiency programs in the U.S. The paper then presents our set of projections of future spending and savings from such programs, highlighting key themes. Projected energy savings are compared to what might be required under a future national EEPS (or broader clean energy standard that includes energy efficiency), in order to gauge the potential incremental impact of such policies. In addition, the carbon emission reductions associated with our projection of energy savings from ratepayer-funded programs is compared to the total emission reductions that might be required under the American Clean Energy and Security Act of 2009 (aka, the Waxman-Markey bill), which was passed by the U.S. House of Representatives in June 2009 and would establish a cap on total greenhouse gas emission for many sectors of the U.S. economy. Last, the paper discusses some of the major obstacles and challenges that states and program administrators may face over the coming decade, as they seek to dramatically ramp-up ratepayer-funded energy efficiency program activity, as projected.« less

The Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) contains criteria for psychiatric diagnoses that reflect advances in the science and conceptualization of mental disorders and address the needs of clinicians. DSM-5 also recommends research on dimensional measures of cross-cutting symptoms and diagnostic severity, which are expected to better capture patients' experiences with mental disorders. Prior to its May 2013 release, the American Psychiatric Association (APA) conducted field trials to examine the feasibility, clinical utility, reliability, and where possible, the validity of proposed DSM-5 diagnostic criteria and dimensional measures. The methods and measures proposed for the DSM-5 field trials were pilot tested in adult and child/adolescent clinical samples, with the goal to identify and correct design and procedural problems with the proposed methods before resources were expended for the larger DSM-5 Field Trials. Results allowed for the refinement of the protocols, procedures, and measures, which facilitated recruitment, implementation, and completion of the DSM-5 Field Trials. These results highlight the benefits of pilot studies in planning large multisite studies. Copyright © 2013, American Psychiatric Association. All rights reserved.

Exploring efficacy of residential energy efficiency programs in Florida

NASA Astrophysics Data System (ADS)

Taylor, Nicholas Wade

Electric utilities, government agencies, and private interests in the U.S. have committed and continue to invest substantial resources in the pursuit of energy efficiency and conservation through demand-side management (DSM) programs. Program investments, and the demand for impact evaluations that accompany them, are projected to grow in coming years due to increased pressure from state-level energy regulation, costs and challenges of building additional production capacity, fuel costs and potential carbon or renewable energy regulation. This dissertation provides detailed analyses of ex-post energy savings from energy efficiency programs in three key sectors of residential buildings: new, single-family, detached homes; retrofits to existing single-family, detached homes; and retrofits to existing multifamily housing units. Each of the energy efficiency programs analyzed resulted in statistically significant energy savings at the full program group level, yet savings for individual participants and participant subgroups were highly variable. Even though savings estimates were statistically greater than zero, those energy savings did not always meet expectations. Results also show that high variability in energy savings among participant groups or subgroups can negatively impact overall program performance and can undermine marketing efforts for future participation. Design, implementation, and continued support of conservation programs based solely on deemed or projected savings is inherently counter to the pursuit of meaningful energy conservation and reductions in greenhouse gas emissions. To fully understand and optimize program impacts, consistent and robust measurement and verification protocols must be instituted in the design phase and maintained over time. Furthermore, marketing for program participation must target those who have the greatest opportunity for savings. In most utility territories it is not possible to gain access to the type of large scale datasets that would facilitate robust program analysis. Along with measuring and optimizing energy conservation programs, utilities should provide public access to historical consumption data. Open access to data, program optimization, consistent measurement and verification and transparency in reported savings are essential to reducing energy use and its associated environmental impacts.

Demand-side management: Why ratemaking should`nt control tax policy

As utilities spend money on demand-side management (DSM) programs, they usually deduct their costs currently as ordinary and necessary business expenses. However, state regulators may force deferral of DSM costs for ratemaking purposes, with possible consequences on tax returns. When regulators defer DSM costs, the Internal Revenue Service (IRS) has offered several theories to challenge current tax deductions. One theory requires capitilization instead of a current deduction if regulators include the DSM cost in rate base and provide for a rate of return on the balance. The IRS explained this theory two years ago in a White Paper on conservationmore » expenses: The direct relationship between a rate of return allowed by the Regulator for conservation expenditures allowed in rate base and future profits establishes a prima facie case for capitalization under the future benefit standard.

In the early 1990s, only a handful of utilities offered their customers a choice of purchasing electricity generated from renewable energy sources. Today, nearly 600 utilities in regulated electricity markets--or almost 20% of all utilities nationally--provide their customers a "green power" option. Because some utilities offer programs in conjunction with cooperative associations or other publicly owned power entities, the number of distinct programs totals about 125. Through these programs, more than 40 million customers spanning 34 states have the ability to purchase renewable energy to meet some portion or all of their electricity needs--or make contributions to support the developmentmore » of renewable energy resources.

This article provides a brief overview of the development of the diagnostic criteria for eating disorders in DSM-IV. The process by which DSM-IV was developed is reviewed, including perspectives on what constitutes diagnostic validity and clinical utility, and their importance in assessing proposed changes in diagnostic criteria. The question of whether alterations in diagnostic criteria would clearly improve clinical utility was a major consideration in the DSM-IV process. Because of concerns that changes in diagnostic criteria would be disruptive and might entail loss of established knowledge, the DSM-IV Task Force assumed a generally conservative stance vis-à-vis change. The process of developing DSM-V is just beginning, and it is far from clear what alterations in diagnostic criteria for eating disorders will occur. However, the evolution of DSM-IV may provide a useful perspective on the development of DSM-V. (c) 2007 by Wiley Periodicals, Inc.

1982-01-01

A summary of recent plants and experiences on current large wind turbine (WT) tests being conducted by electric utilities is provided. The test programs discussed do not include federal research and development (R&D) programs, many of which are also being conducted in conjunction with electric utilities. The information presented is being assembled in a project, funded by the Electric Power Research Institute (EPRI), the objective of which is to provide electric utilities with timely summaries of test performance on key large wind turbines. A summary of key tests, test instrumentation, and recent results and plans is given. During the past year, many of the utility test programs initiated have encountered test difficulties that required specific WT design changes. However, test results to date continue to indicate that long-term machine performance and cost-effectiveness are achievable.

The prevalence of post-traumatic stress disorder (PTSD) in US combat soldiers: a head-to-head comparison of DSM-5 versus DSM-IV-TR symptom criteria with the PTSD checklist.

PubMed

Hoge, Charles W; Riviere, Lyndon A; Wilk, Joshua E; Herrell, Richard K; Weathers, Frank W

2014-09-01

The definition of post-traumatic stress disorder (PTSD) underwent substantial changes in the 2013 edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5). How this will affect estimates of prevalence, whether clinical utility has been improved, and how many individuals who meet symptom criteria according to the previous definition will not meet new criteria is unknown. Updated screening instruments, including the PTSD checklist (PCL), have not been compared with previously validated methods through head-to-head comparisons. We compared the new 20-item PCL, mapped to DSM-5 (PCL-5), with the original validated 17-item specific stressor version (PCL-S) in 1822 US infantry soldiers, including 946 soldiers who had been deployed to Iraq or Afghanistan. Surveys were administered in November, 2013. Soldiers alternately received either of two surveys that were identical except for the order of the two PCL versions (911 per group). Standardised scales measured major depression, generalised anxiety, alcohol misuse, and functional impairment. In analysis of all soldiers, 224 (13%) screened positive for PTSD by DSM-IV-TR criteria and 216 (12%) screened positive by DSM-5 criteria (κ 0·67). In soldiers exposed to combat, 177 (19%) screened positive by DSM-IV-TR and 165 (18%) screened positive by DSM-5 criteria (0·66). However, of 221 soldiers with complete data who met DSM-IV-TR criteria, 67 (30%) did not meet DSM-5 criteria, and 59 additional soldiers met only DSM-5 criteria. PCL-5 scores from 15-38 performed similarly to PCL-S scores of 30-50; a PCL-5 score of 38 gave optimum agreement with a PCL-S of 50. The two definitions showed nearly identical association with other psychiatric disorders and functional impairment. Our findings showed the PCL-5 to be equivalent to the validated PCL-S. However, the new PTSD symptom criteria do not seem to have greater clinical utility, and a high percentage of soldiers who met criteria by one definition did not meet the other criteria. Clinicians need to consider how to manage discordant outcomes, particularly for service members and veterans with PTSD who no longer meet criteria under DSM-5.

2015-06-01

This study sought to evaluate the construct validity of schizoid personality disorder (SZPD) by investigating a sample of 2,619 patients from the Norwegian Network of Personality-Focused Treatment Programs by a variety of statistical techniques. Nineteen patients (0.7%) reached the diagnostic threshold of SZPD. Results from the factor analyses indicated that SZPD consists of three factors: social detachment, withdrawal, and restricted affectivity/ anhedonia. Overall, internal consistency and diagnostic efficiency were poor and best for the criteria that belong to the social detachment factor. These findings pose serious questions about the clinical utility of SZPD as a diagnostic category. On the other hand, the three factors were in concordance with findings from previous studies and with the trait model for personality disorders in DSM-5, supporting the validity of SZPD as a dimensional construct. The authors recommend that SZPD should be deleted as a diagnostic category in future editions of DSM-5.

The six most essential questions in psychiatric diagnosis: a pluralogue part 3: issues of utility and alternative approaches in psychiatric diagnosis

PubMed Central

2012-01-01

In face of the multiple controversies surrounding the DSM process in general and the development of DSM-5 in particular, we have organized a discussion around what we consider six essential questions in further work on the DSM. The six questions involve: 1) the nature of a mental disorder; 2) the definition of mental disorder; 3) the issue of whether, in the current state of psychiatric science, DSM-5 should assume a cautious, conservative posture or an assertive, transformative posture; 4) the role of pragmatic considerations in the construction of DSM-5; 5) the issue of utility of the DSM – whether DSM-III and IV have been designed more for clinicians or researchers, and how this conflict should be dealt with in the new manual; and 6) the possibility and advisability, given all the problems with DSM-III and IV, of designing a different diagnostic system. Part 1 of this article took up the first two questions. Part 2 took up the second two questions. Part 3 now deals with Questions 5 & 6. Question 5 confronts the issue of utility, whether the manual design of DSM-III and IV favors clinicians or researchers, and what that means for DSM-5. Our final question, Question 6, takes up a concluding issue, whether the acknowledged problems with the earlier DSMs warrants a significant overhaul of DSM-5 and future manuals. As in Parts 1 & 2 of this article, the general introduction, as well as the introductions and conclusions for the specific questions, are written by James Phillips, and the responses to commentaries are written by Allen Frances.

Three empirical essays on energy and labor economics

NASA Astrophysics Data System (ADS)

Chow, Melissa

This dissertation analyzes the differences between private and non-private firms in two contexts. Chapters 1 and 2 examine the electricity industry in the United States and the motivation behind electric utilities' usage of demand side management programs. The first chapter focuses on load management programs, which decrease electricity demand during the peak hours of the day. It looks into the impact of a plausibly exogenous decrease in natural gas prices on the utilization and capacity of these programs. The second chapter analyzes the relationship between electricity market deregulation and electric utilities' energy efficiency activity. The third chapter investigates the impact of Chinese enterprise restructuring on employment, wage bills, and productivity. All three chapters show that different objectives due to ownership type lead to differences in firm behavior.

The report is an overview of electric energy efficiency programs. It takes a concise look at what states are doing to encourage energy efficiency and how it impacts electric utilities. Energy efficiency programs began to be offered by utilities as a response to the energy crises of the 1970s. These regulatory-driven programs peaked in the early-1990s and then tapered off as deregulation took hold. Today, rising electricity prices, environmental concerns, and national security issues have renewed interest in increasing energy efficiency as an alternative to additional supply. In response, new methods for administering, managing, and delivering energy efficiency programs aremore » being implemented. Topics covered in the report include: Analysis of the benefits of energy efficiency and key methods for achieving energy efficiency; evaluation of the business drivers spurring increased energy efficiency; Discussion of the major barriers to expanding energy efficiency programs; evaluation of the economic impacts of energy efficiency; discussion of the history of electric utility energy efficiency efforts; analysis of the impact of energy efficiency on utility profits and methods for protecting profitability; Discussion of non-utility management of energy efficiency programs; evaluation of major methods to spur energy efficiency - systems benefit charges, resource planning, and resource standards; and, analysis of the alternatives for encouraging customer participation in energy efficiency programs.« less

The Electric Vehicle Development Corp. (EVDV) expects EV fleets to find a market for urban driving, especially among service fleets, once mass production begins. Electric utilities joined to form EVDC in order to keep abreast of research developments and the results of demonstrations taking place in several cities, where driver acceptance in utility demonstration programs is high. Major auto makers still need persuasion to develop a commercial prototype. Marketing will focus on controlled fleets having the management skills and the motivation to make the program work.

Green Power Marketing in the United States: A Status Report (Ninth Edition)

DOE Office of Scientific and Technical Information (OSTI.GOV)

Bird, L.; Swezey, B.

Voluntary consumer decisions to purchase electricity supplied by renewable energy sources represent a powerful market support mechanism for renewable energy development. Beginning in the early 1990s, a small number of U.S. utilities began offering ''green power'' options to their customers. Since then, these products have become more prevalent, both from traditional utilities and from marketers operating in states that have introduced competition into their retail electricity markets. Today, more than half of all U.S. consumers have an option to purchase some type of green power product from a retail electricity provider. Currently, more than 600 utilities, or about 20% ofmore » utilities nationally, offer green power programs to customers. These programs allow customers to purchase some portion of their power supply as renewable energy--almost always at a higher price--or to contribute funds for the utility to invest in renewable energy development. The term ''green pricing'' is typically used to refer to these utility programs offered in regulated or noncompetitive electricity markets.

Impact of Large Scale Energy Efficiency Programs On Consumer Tariffs and Utility Finances in India

DOE Office of Scientific and Technical Information (OSTI.GOV)

Abhyankar, Nikit; Phadke, Amol

2011-01-20

Large-scale EE programs would modestly increase tariffs but reduce consumers' electricity bills significantly. However, the primary benefit of EE programs is a significant reduction in power shortages, which might make these programs politically acceptable even if tariffs increase. To increase political support, utilities could pursue programs that would result in minimal tariff increases. This can be achieved in four ways: (a) focus only on low-cost programs (such as replacing electric water heaters with gas water heaters); (b) sell power conserved through the EE program to the market at a price higher than the cost of peak power purchase; (c) focusmore » on programs where a partial utility subsidy of incremental capital cost might work and (d) increase the number of participant consumers by offering a basket of EE programs to fit all consumer subcategories and tariff tiers. Large scale EE programs can result in consistently negative cash flows and significantly erode the utility's overall profitability. In case the utility is facing shortages, the cash flow is very sensitive to the marginal tariff of the unmet demand. This will have an important bearing on the choice of EE programs in Indian states where low-paying rural and agricultural consumers form the majority of the unmet demand. These findings clearly call for a flexible, sustainable solution to the cash-flow management issue. One option is to include a mechanism like FAC in the utility incentive mechanism. Another sustainable solution might be to have the net program cost and revenue loss built into utility's revenue requirement and thus into consumer tariffs up front. However, the latter approach requires institutionalization of EE as a resource. The utility incentive mechanisms would be able to address the utility disincentive of forgone long-run return but have a minor impact on consumer benefits. Fundamentally, providing incentives for EE programs to make them comparable to supply-side investments is a way of moving the electricity sector toward a model focused on providing energy services rather than providing electricity.« less

Disqualified qualifiers: evaluating the utility of the revised DSM-5 definition of potentially traumatic events among area youth following the Boston marathon bombing.

Chou, Tommy; Carpenter, Aubrey L; Kerns, Caroline E; Elkins, R Meredith; Green, Jennifer Greif; Comer, Jonathan S

2017-04-01

The DSM-5 includes a revised definition of the experiences that qualify as potentially traumatic events. This revised definition now offers a clearer and more exclusive definition of what qualifies as a traumatic exposure, but little is known about the revision's applicability to youth populations. The present study evaluated the predictive utility of the revised DSM definitional boundaries of traumatic exposure in a sample of youth exposed to the 2013 Boston Marathon bombing and related events METHODS: Caregivers (N = 460) completed surveys 2 to 6 months postbombing about youth experiences during the events and youth posttraumatic stress (PTS) symptoms RESULTS: Experiencing DSM-5 qualifying traumatic events (DSM-5 QTEs) significantly predicted child PTS symptoms (PTSS), whereas DSM-5 nonqualifying stressful experiences (DSM-5 non-QSEs) did not after accounting for DSM-5 QTEs. Importantly, child age moderated the relationship between DSM-5 QTEs and PTSS such that children 7 and older who experienced DSM-5 QTEs showed greater postbombing PTSS, whereas there was no such relationship in children ages 6 and below CONCLUSIONS: Data largely support the revised posttraumatic stress disorder (PTSD) definition of QTEs in older youth, and also highlight the need for further refinement of the QTE definition for children ages 6 and below. © 2016 Wiley Periodicals, Inc.

A case-history format was utilized to compare interrater agreement on childhood and adolescent psychiatric disorders, using DSM-II and DSM-III. The average interrater agreement was 57% for DSM-II and 54% for axis I (clinical psychiatric syndrome) of DSM-III. There was high agreement in both systems on cases of psychosis, conduct disorder, hyperactivity, and mental retardation, with DSM-III appearing slightly better. There was noteworthy interrater disagreement in both systems for "anxiety" disorders, complex cases, and in the subtyping of depression. Overall, the reliability of DSM-III appears to be good and is comparable with that of DSM-II and other classification systems of childhood psychiatric disorders.

An analytics of electricity consumption characteristics based on principal component analysis

NASA Astrophysics Data System (ADS)

Feng, Junshu

2018-02-01

Abstract . More detailed analysis of the electricity consumption characteristics can make demand side management (DSM) much more targeted. In this paper, an analytics of electricity consumption characteristics based on principal component analysis (PCA) is given, which the PCA method can be used in to extract the main typical characteristics of electricity consumers. Then, electricity consumption characteristics matrix is designed, which can make a comparison of different typical electricity consumption characteristics between different types of consumers, such as industrial consumers, commercial consumers and residents. In our case study, the electricity consumption has been mainly divided into four characteristics: extreme peak using, peak using, peak-shifting using and others. Moreover, it has been found that industrial consumers shift their peak load often, meanwhile commercial and residential consumers have more peak-time consumption. The conclusions can provide decision support of DSM for the government and power providers.

Utility photovoltaic group: Status report

Serfass, Jeffrey A.; Hester, Stephen L.; Wills, Bethany N.

1996-01-01

The Utility PhotoVoltaic Group (UPVG) was formed in October of 1992 with a mission to accelerate the use of cost-effective small-scale and emerging grid-connected applications of photovoltaics for the benefit of electric utilities and their customers. The UPVG is now implementing a program to install up to 50 megawatts of photovoltaics in small-scale and grid-connected applications. This program, called TEAM-UP, is a partnership of the U.S. electric utility industry and the U.S. Department of Energy to help develop utility PV markets. TEAM-UP is a utility-directed program to significantly increase utility PV experience by promoting installations of utility PV systems. Two primary program areas are proposed for TEAM-UP: (1) Small-Scale Applications (SSA)—an initiative to aggregate utility purchases of small-scale, grid-independent applications; and (2) Grid-Connected Applications (GCA)—an initiative to identify and competitively award cost-sharing contracts for grid-connected PV systems with high market growth potential, or collective purchase programs involving multiple buyers. This paper describes these programs and outlines the schedule, the procurement status, and the results of the TEAM-UP process.

The present review was conducted in order to evaluate the current diagnostic criteria for specific phobia (SP) in light of the empirical evidence gathered since DSM-IV and to propose changes to DSM-V where change is clearly and reliably indicated by the evidence. In response to questions put forth by the DSM-V Anxiety, OC Spectrum, Posttraumatic, and Dissociative Disorder Work Group, four primary areas were determined for this review: the accuracy and utility of the current SP type classification system, the validity of test anxiety as a type of SP, the boundary between agoraphobia and SP, and the reliability and utility of the diagnostic criteria for SP. Developmental issues are addressed within each area. Literature reviews examining academic findings published between 1994 and 2009 were carried out and the results are included herein. The review presents a number of options and preliminary recommendations to be considered for DSM-V. All of these recommendations should be considered tentative as they await the field trials and expert consensus necessary prior to their inclusion in the DSM-V. The present review also reveals a great need for future research in the area of SP and directions for such research is provided.

Tacit Knowledge Capture and the Brain-Drain at Electrical Utilities

NASA Astrophysics Data System (ADS)

Perjanik, Nicholas Steven

As a consequence of an aging workforce, electric utilities are at risk of losing their most experienced and knowledgeable electrical engineers. In this research, the problem was a lack of understanding of what electric utilities were doing to capture the tacit knowledge or know-how of these engineers. The purpose of this qualitative research study was to explore the tacit knowledge capture strategies currently used in the industry by conducting a case study of 7 U.S. electrical utilities that have demonstrated an industry commitment to improving operational standards. The research question addressed the implemented strategies to capture the tacit knowledge of retiring electrical engineers and technical personnel. The research methodology involved a qualitative embedded case study. The theories used in this study included knowledge creation theory, resource-based theory, and organizational learning theory. Data were collected through one time interviews of a senior electrical engineer or technician within each utility and a workforce planning or training professional within 2 of the 7 utilities. The analysis included the use of triangulation and content analysis strategies. Ten tacit knowledge capture strategies were identified: (a) formal and informal on-boarding mentorship and apprenticeship programs, (b) formal and informal off-boarding mentorship programs, (c) formal and informal training programs, (d) using lessons learned during training sessions, (e) communities of practice, (f) technology enabled tools, (g) storytelling, (h) exit interviews, (i) rehiring of retirees as consultants, and (j) knowledge risk assessments. This research contributes to social change by offering strategies to capture the know-how needed to ensure operational continuity in the delivery of safe, reliable, and sustainable power.

Suicidal behavior on Axis VI: clinical data supporting a sixth Axis for DSM-V.

Oquendo and colleagues (Oquendo, Baca-García, Mann, & Giner, 2008; Oquendo & Currier, 2009) recommend that DSM-V emphasize suicide risk assessment on a sixth axis, thereby increasing regularity of suicide risk assessments. We propose that evidence of nonredundancy with Axis V - Global Assessment of Functioning (GAF) is one piece of data that can serve as a starting point for a line of research establishing incremental predictive utility for a separate suicide risk assessment in the DSM framework. A standardized suicide risk assessment protocol, measures of depressive, anxious, and eating disordered symptomatology, as well as an index of comorbidity were administered to a sample of 412 adult outpatients. Our data indicate that data from standardized suicide risk assessments are associated with indices of symptomatology severity as well as comorbidity, controlling for GAF. These results support the nonredundancy of the assessments and suggest the utility of longitudinal investigations of the predictive utility of a sixth DSM axis in the assessment of suicide risk.

The functional role of the voltage-gated K(+) (K(V)) channels in human detrusor smooth muscle (DSM) is largely unexplored. Here, we provide molecular, electrophysiological, and functional evidence for the expression of K(V)2.1, K(V)2.2, and the electrically silent K(V)9.3 subunits in human DSM. Stromatoxin-1 (ScTx1), a selective inhibitor of K(V)2.1, K(V)2.2, and K(V)4.2 homotetrameric channels and of K(V)2.1/9.3 heterotetrameric channels, was used to examine the role of these channels in human DSM function. Human DSM tissues were obtained during open bladder surgeries from patients without a history of overactive bladder. Freshly isolated human DSM cells were studied using RT-PCR, immunocytochemistry, live-cell Ca(2+) imaging, and the perforated whole cell patch-clamp technique. Isometric DSM tension recordings of human DSM isolated strips were conducted using tissue baths. RT-PCR experiments showed mRNA expression of K(V)2.1, K(V)2.2, and K(V)9.3 (but not K(V)4.2) channel subunits in human isolated DSM cells. K(V)2.1 and K(V)2.2 protein expression was confirmed by Western blot analysis and immunocytochemistry. Perforated whole cell patch-clamp experiments revealed that ScTx1 (100 nM) inhibited the amplitude of the voltage step-induced K(V) current in freshly isolated human DSM cells. ScTx1 (100 nM) significantly increased the intracellular Ca(2+) level in DSM cells. In human DSM isolated strips, ScTx1 (100 nM) increased the spontaneous phasic contraction amplitude and muscle force, and enhanced the amplitude of the electrical field stimulation-induced contractions within the range of 3.5-30 Hz stimulation frequencies. These findings reveal that ScTx1-sensitive K(V)2-containing channels are key regulators of human DSM excitability and contractility and may represent new targets for pharmacological or genetic intervention for bladder dysfunction.

Retention or deletion of personality disorder diagnoses for DSM-5: an expert consensus approach.

One of the official proposals for the fifth edition of the American Psychiatric Association's (APA) diagnostic manual (DSM-5) is to delete half of the existing personality disorders (i.e., dependent, histrionic, narcissistic, paranoid, and schizoid). Within the APA guidelines for DSM-5 decisions, it is stated that there should be expert consensus agreement for the deletion of a diagnostic category. Additionally, categories to be deleted should have low clinical utility and/or minimal evidence for validity. The current study surveyed members of two personality disorder associations (n = 146) with respect to the utility, validity, and status of each DSM-IV-TR personality disorder diagnosis. Findings indicated that the proposal to delete five of the personality disorders lacks consensus support within the personality disorder community.

Associations, Alliances, and Allies, a seminar and workshop sponsored by the Electric Power Research Institute, was held in Memphis, Tennessee, April 10--11, 1991. The focus of the meeting was relationships forged between electric utilities and trade allies that sell residential heat pumps. one hundred and seven representatives of electric utilities, dealer/contractors, manufacturers, and consultants attended. Electric utility trade ally programs run the gamut from coop advertising to heat pump association to elaborate technician training programs. All utility participants recognize the important programs, since it is the trade ally who sells, installs, and services heat pumps, while it is the electricmore » utility who gets blamed if the heat pumps fail to operate properly or are inefficient. Heat pumps are efficient and effective, but their efficiency and effectiveness depends critically upon the quality of installation and maintenance. A utility can thus help to ensure satisfied customers and can also help to achieve its own load shape objectives by working closely with its trade allies, the dealers, contractors, manufacturers, and distributors. Attendees spent the morning sessions of the two day meeting in plenary sessions, hearing about utility and dealer heat pump programs and issues. Afternoon roundtable discussions provided structured forums to discuss: Advertising; Heat pump association startup and operation; Rebates and incentives; Technician training school and centers; Installation inspection and dealer qualification; and Heat pump association training. These proceedings report on the papers presented in the morning plenary sessions and summarize the main points discussed in the afternoon workshops.« less

Electricity-driven metabolic shift through direct electron uptake by electroactive heterotroph Clostridium pasteurianum

Choi, Okkyoung; Kim, Taeyeon; Woo, Han Min; Um, Youngsoon

2014-01-01

Although microbes directly accepting electrons from a cathode have been applied for CO2 reduction to produce multicarbon-compounds, a high electron demand and low product concentration are critical limitations. Alternatively, the utilization of electrons as a co-reducing power during fermentation has been attempted, but there must be exogenous mediators due to the lack of an electroactive heterotroph. Here, we show that Clostridium pasteurianum DSM 525 simultaneously utilizes both cathode and substrate as electron donors through direct electron transfer. In a cathode compartment poised at +0.045 V vs. SHE, a metabolic shift in C. pasteurianum occurs toward NADH-consuming metabolite production such as butanol from glucose (20% shift in terms of NADH consumption) and 1,3-propandiol from glycerol (21% shift in terms of NADH consumption). Notably, a small amount of electron uptake significantly induces NADH-consuming pathways over the stoichiometric contribution of the electrons as reducing equivalents. Our results demonstrate a previously unknown electroactivity and metabolic shift in the biochemical-producing heterotroph, opening up the possibility of efficient and enhanced production of electron-dense metabolites using electricity.

Objective Changes in autism diagnostic criteria found in DSM5 may affect Autism Spectrum Disorder (ASD) prevalence, research findings, diagnostic processes and eligibility for clinical and other services. Utilizing our published, total-population Korean prevalence data, we compute DSM5 ASD and Social Communication Disorder (SCD) prevalence and compare them to DSMIV Pervasive Developmental Disorder (PDD) prevalence estimates. We also describe individuals previously diagnosed with DSMIV PDD when diagnoses change with DSM-5 criteria. Method The target population was all 7-12-year-old children in a South Korean community (N= 55,266), those in regular and special education schools and a disability registry. We utilized the Autism Spectrum Screening Questionnaire for systematic, multi-informant screening. Parents of screen-positive children were offered comprehensive assessments using standardized diagnostic procedures, including the Autism Diagnostic Interview-Revised and Autism Diagnostic Observation Schedule. Best estimate clinical diagnoses were made using DSMIV PDD and DSM5 ASD and SCD criteria. Results DSM5 ASD estimated prevalence is 2.20% (CI: 1.77-3.64). Combined DSM-5 ASD and SCD prevalence is virtually same as DSM-IV PDD prevalence (2.64%). Most children with Autistic Disorder (99%), Asperger Disorder (92%), and PDD NOS (63%) met DSM-5 ASD criteria, whereas 1%, 8% and 32%, respectively, met SCD criteria. All remaining children (2% ) had other psychopathology, principally Attention Deficit Hyperactivity Disorder and anxiety disorder. Conclusion Our findings suggest that most individuals with a prior DSMIV PDD meet DSM5 diagnostic criteria for ASD and SCD. PDD, ASD or SCD, extant diagnostic criteria identify a large, clinically meaningful group of individuals and families who require evidence-based services. PMID:24745950

To assess patient satisfaction, perception of self-management, and perception of disease state knowledge with pharmacist-led diabetes and cardiovascular disease state management (DSM) programs. A self-insured chain of grocery store pharmacies in the Kansas City metropolitan area administers pharmacist-led diabetes and cardiovascular DSM programs for eligible employees and dependents. A modified version of the Diabetes Disease State Management Questionnaire was used to assess patient satisfaction with the DSM programs. Demographic information was also collected. Survey items were based on a 5-point Likert scale (1 = strongly disagree and 5 = strongly agree). Patients were eligible to complete the survey if he or she had been in at least 1 DSM program for 6 months. Data were assessed using descriptive statistics and analysis of variance. Across 20 pharmacies, 281 eligible participants were identified, and 46% (n = 128) completed a survey. Means for summed items relating to overall satisfaction (8 items), self-management (5 items), and knowledge (4 items) were 36.6/40 (standard deviation [SD] = 3.9), 20.9/25 (SD = 3.4), and 17.6/20 (SD = 2.1), respectively. Participant comments further indicated that the program and pharmacists are helpful and increase motivation and accountability. Positive patient responses to the program support use of pharmacist-led DSM programs. © The Author(s) 2015.

Background Innovative interventions that empower patients in diabetes self-management (DSM) are needed to provide accessible, sustainable, cost-effective patient education and support that surpass current noninteractive interventions. Skills acquired in digital virtual environments (VEs) affect behaviors in the physical world. Some VEs are programmed as real-time three-dimensional representations of various settings via the Internet. For this research, a theoretically grounded VE that facilitates DSM was developed and pilot tested. It offered weekly synchronous DSM education classes, group meetings, and social networking in a community in which participants practiced real world skills such as grocery shopping, exercising, and dining out, allowing for interactive knowledge application. The VE was available 24/7 on the Internet, minimizing access barriers. Objective The objective of this study was to evaluate the feasibility and efficacy of participation in a VE for DSM education and support. Methods This study utilized a single group, pre-mid-post measure design. At 0, 3, and 6 months, we assessed participants’ perceived VE usability and usefulness, self-efficacy, diabetes self-management behaviors, perceived social support, and diabetes knowledge using validated survey measures; and we recorded metabolic indicators (HbA1c, BP, BMI). Process data were continuously collected in the VE (log-ins, voice recordings, locations visited, objects interacted with, and movement). Data analysis included descriptive statistics, t tests to evaluate changes in mediators and outcomes over time, and depiction of utilization and movement data. Results We enrolled 20 participants (13/20, 65% white, 7/20, 35% black), with an age range of 39-72 years (mean age, 54 years) and diabetes duration from 3 months to 25 years. At baseline, 95% (18/19) and 79% (15/19) of participants rated usefulness and ease of use as high on validated surveys with no significant changes at 3 or 6 months. Participants logged into the site a mean of 2.5 hours/week over the course of 6 months. High DSM class attendance was reflected by the largest percentage of time spent in the classroom (48.6%). Self-efficacy, social support, and foot care showed significant improvement (P<.05). There were improvement trends in clinical outcomes that were clinically meaningful but did not reach statistical significance given the small sample size. Conclusions Because relatively little is known about usability, acceptability, and efficacy of health interventions in VEs, this study constitutes an important, innovative first step in exploring the potential of VEs for facilitating DSM. The preliminary data suggest that VEs provide a feasible and useful platform for patients and educators that affects self-management and related mediators. Flexible access to both synchronous and asynchronous diabetes education, skill building activities, and support from a home computer remove barriers to attending clinic-based meetings. This program has potential for improving DSM in an easily disseminated alternative model. PMID:24713420

Elastic Model Transitions: a Hybrid Approach Utilizing Quadratic Inequality Constrained Least Squares (LSQI) and Direct Shape Mapping (DSM)

NASA Technical Reports Server (NTRS)

Jurenko, Robert J.; Bush, T. Jason; Ottander, John A.

2014-01-01

A method for transitioning linear time invariant (LTI) models in time varying simulation is proposed that utilizes both quadratically constrained least squares (LSQI) and Direct Shape Mapping (DSM) algorithms to determine physical displacements. This approach is applicable to the simulation of the elastic behavior of launch vehicles and other structures that utilize multiple LTI finite element model (FEM) derived mode sets that are propagated throughout time. The time invariant nature of the elastic data for discrete segments of the launch vehicle trajectory presents a problem of how to properly transition between models while preserving motion across the transition. In addition, energy may vary between flex models when using a truncated mode set. The LSQI-DSM algorithm can accommodate significant changes in energy between FEM models and carries elastic motion across FEM model transitions. Compared with previous approaches, the LSQI-DSM algorithm shows improvements ranging from a significant reduction to a complete removal of transients across FEM model transitions as well as maintaining elastic motion from the prior state.

To investigate the reliability, validity and utility of DSM-5 illness anxiety disorder (IAD) and somatic symptom disorder (SSD), and explore their overlap with DSM-IV Hypochondriasis in a health anxious sample. Treatment-seeking patients with health anxiety (N=118) completed structured diagnostic interviews to assess DSM-IV Hypochondriasis, DSM-5 IAD, SSD, and comorbid mental disorders, and completed self-report measures of health anxiety, comorbid symptoms, cognitions and behaviours, and service utilization. IAD and SSD were more reliable diagnoses than Hypochondriasis (kappa estimates: IAD: 0.80, SSD: 0.92, Hypochondriasis: 0.60). 45% of patients were diagnosed with SSD, 47% with IAD, and 8% with comorbid IAD/SSD. Most patients with IAD fluctuated between seeking and avoiding care (61%), whereas care-seeking (25%) and care-avoidant subtypes were less common (14%). Half the sample met criteria for DSM-IV Hypochondriasis; of those, 56% met criteria for SSD criteria, 36% for IAD, and 8% for comorbid IAD/SSD. Compared to IAD, SSD was characterized by more severe health anxiety, somatic symptoms, depression, and higher health service use, and higher rates of major depressive disorder, panic disorder and agoraphobia. DSM-5 IAD and SSD classifications reliably detect more cases of clinically significant health anxiety than DSM-IV Hypochondriasis. The differences between IAD and SSD appear to be due to severity. Future research should explore the generalizability of these findings to other samples, and whether diagnostic status predicts treatment response and long-term outcome. Copyright © 2017 Elsevier Inc.

This paper lays out a set of economic criteria to guide the development of electricity conservation programs for industrial customers of the Costa Rican utilities. It puts the problem of utility and other public policy formulation in the industrial conservation field into the context of ongoing economic and trade liberalization in Costa Rica, as well as the financial and political pressures with which the country`s utilities must contend. The need to bolster utility financial performance and the perennial political difficulty of adjusting power rates for inflation and devaluation, not to mention maintaining efficient real levels, puts a premium on controllingmore » the costs of utility conservation programs and increasing the degree of cost recovery over time. Industrial conservation programs in Costa Rica must adopt a certain degree of activation to help overcome serious market failures and imperfections while at the same time avoiding significant distortion of the price signals guiding the ongoing industrial rationalization process and the reactivation of growth.« less

Little is known regarding treatment utilization among individuals meeting DSM-5 criteria for posttraumatic stress disorder (PTSD). Data were analyzed from the third wave of the National Epidemiologic Survey on Alcohol and Related Conditions, a nationally representative sample using DSM-5 criteria. Factors related to increased odds of PTSD treatment utilization for individuals meeting lifetime criteria included some college education versus less than a high school degree (odds ratio [OR]=3.17), having health insurance versus no insurance (OR=2.86), having a comorbid phobia disorder versus not having a phobia disorder (OR=1.36), and greater PTSD symptom count (OR=1.11). Older age (OR=.40), identifying as black or Asian versus white non-Hispanic (OR=.70 and OR=.28, respectively), and greater social functioning (OR=.98) were associated with decreased odds of PTSD treatment utilization. Results highlight factors that may be useful in identifying population subgroups with PTSD that are at risk for underutilization of services.

In 1981, the utility introduced a program of reduced electric rates (Area Development Rate) for economic development to help revitalize eight areas of the South Bronx and Brooklyn that were economically disadvantaged neighborhoods. This program has been very successful. It has helped produce jobs; it has helped to raise business activity in some of the most economically depressed areas of the nation; and, by increasing the usage of underutilized Company distribution facilities, it hasmore » increased Con Edison's efficiency to benefit all customers. It is established that this program resulted in a more than 24 percent average reduction of electric costs for participating companies. After recognition of this successful area development program, in late 1983, the N.Y. State legislature announced that as a matter of public policy electric utility rate incentives should, where appropriate, be used to foster economic activity in the state. The legislature found that ''the cost of utility services can be a significant factor in retaining and attracting healthy businesses and the employment opportunities and economic activity that they provide. The Law empowered the N.Y.

Energy demand management, also known as demand side management (DSM), is the modification of consumer demand for energy through various methods such as smart metering, incentive based schemes, payments for turning off loads or rescheduling loads. Usually, the goal of demand side management is to encourage the consumer to use less power during periods of peak demand, or to move the time of energy use to off-peak times. Peak demand management does not necessarily decrease total energy consumption, but could be expected to reduce the need for investments in networks and/or power plants for meeting peak demands. Electricity use can vary dramatically on short and medium time frames, and the pricing system may not reflect the instantaneous cost as additional higher-cost that are brought on-line. In addition, the capacity or willingness of electricity consumers to adjust to prices by altering elasticity of demand may be low, particularly over short time frames. In the scenario of Indian grid setup, the retail customers do not follow real-time pricing and it is difficult to incentivize the utility companies for continuing the peak demand supply. A question for the future is how deeper penetration of renewable will be handled? This is a challenging problem since one has to deal with high variability, while managing loss of load probabilities. In the case of managing the peak demand using agriculture, in the future as smart metering matures with automatic turn on/off for a pump, it will become possible to provide an ensured amount of water or energy to the farmer while keeping the grid energized for 24 hours. Supply scenarios will include the possibility of much larger penetration of solar and wind into the grid. While, in absolute terms these sources are small contributors, their role will inevitably grow but DSM using agriculture could help reduce the capital cost. The other option is of advancing or delaying pump operating cycle even by several hours, will still ensure soil moisture requirements met while, balancing the overall system load with generation, reducing critical power mismatches. Through this presentation the author will describe different techniques and results from field experiments in India.

To review evidence of the validity and clinical utility of Purging Disorder and examine options for the Diagnostic and Statistical Manual of Mental Disorders fifth edition (DSM-V). Articles were identified by computerized and manual searches and reviewed to address five questions about Purging Disorder: Is there "ample" literature? Is the syndrome clearly defined? Can it be measured and diagnosed reliably? Can it be differentiated from other eating disorders? Is there evidence of syndrome validity? Although empirical classification and concurrent validity studies provide emerging support for the distinctiveness of Purging Disorder, questions remain about definition, diagnostic reliability in clinical settings, and clinical utility (i.e., prognostic validity). We discuss strengths and weaknesses associated with various options for the status of Purging Disorder in the DSM-V ranging from making no changes from DSM-IV to designating Purging Disorder a diagnosis on equal footing with Anorexia Nervosa and Bulimia Nervosa.

The Developmental Diagnostic Dimensional Interview-short version (3Di-sv) provides a brief standardized parental interview for diagnosing autism spectrum disorder (ASD). This study explored its validity, and compatibility with DSM-5 ASD. 3Di-sv classifications showed good sensitivity but low specificity when compared to ADOS-2-confirmed clinical diagnosis. Confirmatory factor analyses found a better fit against a DSM-5 model than a DSM-IV-TR model of ASD. Exploration of the content validity of the 3Di-sv for the DSM-5 revealed some construct underrepresentation, therefore we obtained data from a panel of 3Di-trained clinicians from ASD-specialized centers to recommend items to fill these gaps. Taken together, the 3Di-sv provides a solid basis to create a similar instrument suitable for DSM-5. Concrete recommendations are provided to improve DSM-5 compatibility.

This study investigates the influence of tomato and feijoa juices as fermentable carriers of Lactobacillus plantarum (LP DSM20205) on the ability of the bacterium to improve intestinal barrier function using the trans-epithelial electrical resistance (TEER) assay in an apical anaerobic model. The survival of LP DSM20205 in different fruit juices during in vitro digestion, its adhesion capacity, and potential cytotoxic effect on Caco-2 cells were also studied. The results showed that carrier fruit juices have a significant influence on LP DSM20205 growth, survival during in vitro digestion, adhesion capacity, and TEER. All fermented samples were not cytotoxic to Caco-2 cells. The fermented tomato juice showed the largest improvement to intestinal barrier integrity. The digested fermented juices did not increase TEER, although the LP DSM20205 in these samples adhered well. Therefore, LP DSM20205 has the potential to be used as a probiotic in the production of fermented tomato and feijoa juices.

Personality disorder in DSM-5: an oral history.

PubMed

Zachar, P; Krueger, R F; Kendler, K S

2016-01-01

As the revision process leading to DSM-5 began, the domain of personality disorder embodied the highest aspirations for major change. After an initial prototype-based proposal failed to gain acceptance, the Personality and Personality Disorders Work Group (P&PDWG) developed a hybrid model containing categorical and dimensional components. A clash of perspectives both within the P&PDWG and between the P&PDWG and DSM-5 oversight committees led to the rejection of this proposal from the main body of DSM-5. Major issues included conflicting ways of conceptualizing validation, differences of opinion from personality disorder experts outside the P&PDWG, divergent concepts of the magnitude of evidence needed to support substantial changes, and the disagreements about clinical utility of the hybrid model. Despite these setbacks, the 'Alternative DSM-5 Model of Personality Disorder' is presented in Section III of the DSM-5. Further research should clarify its performance relative to the DSM-IV criteria reprinted in the main DSM-5 text.

Investigating the DSM-5 severity specifiers based on thinness for adults with anorexia nervosa.

PubMed

Reas, Deborah Lynn; Rø, Øyvind

2017-08-01

The DSM-5 severity classification scheme for adults with anorexia nervosa (AN) is based upon current body mass index (BMI; kg/m 2 ). This study examined the utility of the DSM-5 severity specifiers for adults with AN in relation to core cognitive and behavioral features of eating pathology and associated psychosocial impairment. A clinical sample of 146 adult AN patients (140 women, 6 men) were categorized using DSM-5 current BMI severity specifiers and assessed with the Eating Disorder Examination-Questionnaire (EDE-Q) and Clinical Impairment Assessment (CIA). A total of 34 (23.3%) patients were categorized as mild (>=17.0 BMI), 35 (24.0%) as moderate (16-16.99 BMI), 32 (21.9%) as severe (15-15.99 BMI), and 45 (30.8%) as extreme (<15 BMI). No significant group differences were found for age, CIA and EDE-Q global or subscale scores, frequency of laxative use, self-induced vomiting, binge eating, or excessive exercise. This study found little empirical evidence to support the utility of DSM-5 severity rating scheme to differentiate adults with AN in terms of core eating disorder pathology or associated psychosocial impairment. © 2017 Wiley Periodicals, Inc.

Implications for the Measurement of Psychopathy in the DSM-5 Using the Computerized Adaptive Test of Personality Disorder.

2018-06-06

This study investigated the ability of the Computerized Adaptive Test of Personality Disorder (CAT-PD) model to capture psychopathy in a sample consisting of U.S. (n = 565) and Australian (n = 99) undergraduates and a U.S. community sample (n = 210). More specifically, this study examined (a) the association between CAT-PD facets, particularly those consistent with DSM-5 Section III antisocial personality disorder (ASPD), and measures of psychopathy, (b) the extent to which CAT-PD ASPD traits improve on DSM-5 Section II ASPD in measuring psychopathy, and (c) the utility of measuring functional impairment in additional to dimensional traits in assessing psychopathy. Analyses revealed CAT-PD ASPD traits, including traits' associations with Section III psychopathy specifier, were strongly associated with measures of psychopathy. Furthermore, CAT-PD ASPD was found to be an improvement over DSM-5 Section II ASPD in measuring psychopathy, and the dimensional nature of the CAT-PD was found to render the addition of measures of impairment unnecessary. These findings generally support the utility of the CAT-PD in the measurement of psychopathy, particularly as it relates to the dimensional assessment of psychopathy in the DSM-5 alternative model for personality disorder.

The Electrical and physical properties can be used as indicators for measuring soil conditions. One of the methods developed in agricultural systems to obtain information on soil conditions is through measuring of electrical conductivity. Peat soil is one of the natural resources that exist in Indonesia. This study aims to determine the characteristics of peat soil in Rasau village, West Kalimantan. This research was conducted by the properties of electrical conductivity and water content using 5TE Water Contents and EC Sensor equipment, but also to know the change of physical nature of peat soil covering peat soil and peat type. The results showed that the electrical conductivity value of 1-4 samples was 0.02 -0.29 dS/m and the volume water content value (VWC) was 0.255-0.548 m3/m3 and the physical characteristics obtained were peat colour brown to dark brown that allegedly the soil still has a very high content of organic material derived from weathering plants and there are discovery of wood chips, wood powder and leaf powder on the ground. Knowing the information is expected to identify the land needs to be developed to be considered for future peat soil utilization.

Avant le deluge: An investigation of some neglected dimensions of electricity restructuring in California

NASA Astrophysics Data System (ADS)

Golove, William Harry

Chapter One of this dissertation focuses on describing the key participant groups and their principle interests in the restructuring process. The process of reaching agreement on the restructuring plan turned on each major interest group receiving satisfaction of all of its key objectives. Chapter Two explores the effective use of rhetoric in the electricity restructuring debate. Despite a lack of public involvement, the use of rhetoric appears to have been a prominent feature of the public policy process. A series of rhetorical concepts and mechanisms defined. Of these, the notions of rhetorical salience and rhetorical efficacy are most significant. The results of a field test on the impact of the particular examples of these tropes prominent in the restructuring debate on opinions regarding some of the key restructuring issues are presented. Chapter Three describes the sea change in the nature of demand side management (DSM) policy in the state, brought about by the restructuring of the electricity market. Whereas the primary goal of DSM had been resource acquisition, the new policy goal was to be market transformation. This chapter reviews the economic, and other social science theory that led to the development of demand side management programs based on a resource acquisition goal prior to restructuring and, subsequently, to a market transformation objective. Chapter Four examines the performance of the market during the period beginning in early 1998 through the first few months of 2000 at which time both the wholesale and retail markets in California were apparently functioning relatively well. The findings presented in this chapter are the result of a series of semi-structured interviews conducted with non-residential electricity customers that had chosen to receive electric service and, in some cases, value-added services from a competitive retail electricity service provider One of the key conclusions is that market rules appear to be critical to customer experiences with retail competition, yet the relationship between market rules and market development is inadequately understood. The over-arching theme, that the "free market" was inadequate to manage the complexities of the electricity market, is articulated throughout this work.

Photovoltaics as a terrestrial energy source. Volume 2: System value

NASA Technical Reports Server (NTRS)

Smith, J. L.

1980-01-01

Assumptions and techniques employed by the electric utility industry and other electricity planners to make estimates of the future value of photovoltaic (PV) systems interconnected with U.S. electric utilities were examined. Existing estimates of PV value and their interpretation and limitations are discussed. PV value is defined as the marginal private savings accruing to potential PV owners. For utility-owned PV systems, these values are shown to be the after-tax savings in conventional fuel and capacity displaced by the PV output. For non-utility-owned (distributed) systems, the utility's savings in fuel and capacity must first be translated through the electric rate structure (prices) to the potential PV system owner. Base-case estimates of the average value of PV systems to U.S. utilities are presented. The relationship of these results to the PV Program price goals and current energy policy is discussed; the usefulness of PV output quantity goals is also reviewed.

Reducing Gridlock on the Grid: Utility Trends in Managing Peak Electric Load through Residential Demand Response

NASA Astrophysics Data System (ADS)

McDonald, Betsy

Utilities across the United States are piloting residential demand response programs to help manage peak electric demand. Using publicly available program evaluations, this thesis analyzes nine such programs to uncover and synthesize the range of program offerings, goals, enrollment strategies, and customer experiences. This review reveals that program participation, components, and results differ based on a variety of factors, including geographic characteristics, program goals, and implementation strategies. The diversity of program designs and evaluation findings suggests an underlying tension between the need to generate cost-effective program impacts and the desire to increase accessibility so that program benefits are not exclusive to certain segments of the population. For more significant and impactful engagement, program goals may need to shift. State level policy support could help shift program goals toward increasing program accessibility. Future research should explore creative strategies that target existing barriers and allow for more inclusive deployment.

Assessing the clinical utility of agoraphobia in the context of panic disorder.

PubMed

Schmidt, Norman B; Cromer, Kiara R

2008-01-01

In the DSM-IV, a panic disorder (PD) diagnosis includes specification of agoraphobia, which is primarily an index of situational avoidance due to fear of panic. No other anxiety diagnosis requires specification of level of avoidance. This raises the question as to whether agoraphobia provides unique information beyond the core features of PD (i.e., panic attacks and panic-related worry). The incremental validity of agoraphobia, defined using DSM-IV specifiers versus level of situational avoidance, was examined in relation to the expression and treatment of PD (N=146). Analyses indicate that agoraphobia status adds uniquely to the prediction of PD symptoms, impairment, and response to treatment. However, level of situational avoidance, defined either as a continuous or dichotomous variable, appears to have greater utility compared to the DSM-IV method of classifying agoraphobia. In summary, the agoraphobia specifier seems to have clinical utility but this could be improved by focusing on a dimensional assessment of situational avoidance.

The interpersonal core of personality pathology

Hopwood, Christopher J.; Wright, Aidan G.C.; Ansell, Emily B.; Pincus, Aaron L.

2013-01-01

The purpose of this paper is to demonstrate that personality pathology is, at its core, fundamentally interpersonal. We review the proposed DSM-5 Section 3 redefinition of personality pathology involving self and interpersonal dysfunction, which we regard as a substantial improvement over the DSM-IV (and DSM-5 Section 2) definition. We note similarities between the proposed scheme and contemporary interpersonal theory and interpret the DSM-5 Section 3 definition using the underlying assumptions and evidence base of the interpersonal paradigm in clinical psychology. We describe how grounding the proposed DSM-5 Section 3 definition in interpersonal theory, and in particular a focus on the “interpersonal situation”, adds to its theoretical texture, empirical support, and clinical utility. We provide a clinical example that demonstrates the ability of contemporary interpersonal theory to augment the DSM-5 definition of personality pathology. We conclude with directions for further research that could clarify the core of personality pathology, and how interpersonal theory can inform research aimed at enhancing the DSM-5 Section 3 proposal and ultimately justify its migration to DSM-5 Section 2.

2001-01-01

The design of distributed shared memory (DSM) computers liberates users from the duty to distribute data across processors and allows for the incremental development of parallel programs using, for example, OpenMP or Java threads. DSM architecture greatly simplifies the development of parallel programs having good performance on a few processors. However, to achieve a good program scalability on DSM computers requires that the user understand data flow in the application and use various techniques to avoid data traffic congestions. In this paper we discuss a number of such techniques, including data blocking, data placement, data transposition and page size control and evaluate their efficiency on the NAS (NASA Advanced Supercomputing) Parallel Benchmarks. We also present a tool which automates the detection of constructs causing data congestions in Fortran array oriented codes and advises the user on code transformations for improving data traffic in the application.

There is a lack of studies testing accuracy of fast screening methods for alcohol use disorder in mental health settings. We aimed at estimating clinical utility of a standard single-item test for case finding and screening of DSM-5 alcohol use disorder among individuals suffering from anxiety and mood disorders. We recruited adults consecutively referred, in a 12-month period, to an outpatient clinic for anxiety and depressive disorders. We assessed the National Institute on Alcohol Abuse and Alcoholism (NIAAA) single-item test, using the Mini- International Neuropsychiatric Interview (MINI), plus an additional item of Composite International Diagnostic Interview (CIDI) for craving, as reference standard to diagnose a current DSM-5 alcohol use disorder. We estimated sensitivity and specificity of the single-item test, as well as positive and negative Clinical Utility Indexes (CUIs). 242 subjects with anxiety and mood disorders were included. The NIAAA single-item test showed high sensitivity (91.9%) and specificity (91.2%) for DSM-5 alcohol use disorder. The positive CUI was 0.601, whereas the negative one was 0.898, with excellent values also accounting for main individual characteristics (age, gender, diagnosis, psychological distress levels, smoking status). Testing for relevant indexes, we found an excellent clinical utility of the NIAAA single-item test for screening true negative cases. Our findings support a routine use of reliable methods for rapid screening in similar mental health settings. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

Diagnostic Utility of the ADI-R and DSM-5 in the Assessment of Latino Children and Adolescents.

2017-05-01

Latino children in the US are systematically underdiagnosed with Autism Spectrum Disorder (ASD); therefore, it is important that recent changes to the diagnostic process do not exacerbate this pattern of under-identification. Previous research has found that the Autism Diagnostic Interview-Revised (ADI-R) algorithm, based on the Diagnostic and Statistical Manual of Mental Disorder, Fourth Edition, Text Revision (DSM-IV-TR), has limitations with Latino children of Spanish speaking parents. We evaluated whether an ADI-R algorithm based on the new DSM-5 classification for ASD would be more sensitive in identifying Latino children of Spanish speaking parents who have a clinical diagnosis of ASD. Findings suggest that the DSM-5 algorithm shows better sensitivity than the DSM-IV-TR algorithm for Latino children.

This report examines various compensation methodologies for demand response programs in Mexico. This report presents three case studies, including New England, California, and Hawaii. Demand response (DR) can refer to a variety of approaches to changing the amount and timing of customers' electricity use, allowing the electricity supplier to more easily balance electricity supply and demand. The level of compensation for a DR program will depend greatly upon both the regulatory context of the electricity supplier, as well as the economic circumstances of the DR providers. For a regulated utility, a proposed compensation level may need to pass regulatory approval.more » To determine the value of DR resources, a regulatory body typically seeks to determine the costs that the utility would avoid if demand-side resources 'produce' energy.« less

Parajuli, Shankar P; Hristov, Kiril L; Soder, Rupal P; Kellett, Whitney F; Petkov, Georgi V

2013-01-01

Background and Purpose Overactive bladder (OAB) is often associated with abnormally increased detrusor smooth muscle (DSM) contractions. We used NS309, a selective and potent opener of the small or intermediate conductance Ca2+-activated K+ (SK or IK, respectively) channels, to evaluate how SK/IK channel activation modulates DSM function. Experimental Approach We employed single-cell RT-PCR, immunocytochemistry, whole cell patch-clamp in freshly isolated rat DSM cells and isometric tension recordings of isolated DSM strips to explore how the pharmacological activation of SK/IK channels with NS309 modulates DSM function. Key Results We detected SK3 but not SK1, SK2 or IK channels expression at both mRNA and protein levels by RT-PCR and immunocytochemistry in DSM single cells. NS309 (10 μM) significantly increased the whole cell SK currents and hyperpolarized DSM cell resting membrane potential. The NS309 hyperpolarizing effect was blocked by apamin, a selective SK channel inhibitor. NS309 inhibited the spontaneous phasic contraction amplitude, force, frequency, duration and tone of isolated DSM strips in a concentration-dependent manner. The inhibitory effect of NS309 on spontaneous phasic contractions was blocked by apamin but not by TRAM-34, indicating no functional role of the IK channels in rat DSM. NS309 also significantly inhibited the pharmacologically and electrical field stimulation-induced DSM contractions. Conclusions and Implications Our data reveal that SK3 channel is the main SK/IK subtype in rat DSM. Pharmacological activation of SK3 channels with NS309 decreases rat DSM cell excitability and contractility, suggesting that SK3 channels might be potential therapeutic targets to control OAB associated with detrusor overactivity.

Posttraumatic stress disorder (PTSD) diagnostic criteria have been criticized for including symptoms that overlap with commonly comorbid disorders, which critics argue undermines the validity of the diagnosis and inflates psychiatric comorbidity rates. In response, the upcoming 11th edition of the International Classification of Diseases (ICD-11) will offer PTSD diagnostic criteria that are intended to promote diagnostic accuracy. However, diagnostic utility analyses have not yet assessed whether these criteria minimize diagnostic errors. The present study examined the diagnostic utility of each PTSD symptom in the fifth edition of the Diagnostic and Statistical Manual for Mental Disorders (DSM-5) for males and females. Participants were 1,347 individuals enrolled in a longitudinal national registry of returning veterans receiving care at a Department of Veterans Affairs (VA) facility. Doctoral level clinicians assessed all participants using the PTSD module of the Structured Clinical Interview for DSM. Of the 20 symptoms examined, the majority performed in the fair to poor range on test quality indices. Although a few items did perform in the good (or better) range, only half were ICD-11 symptoms. None of the 20 symptoms demonstrated good quality of efficiency. Results demonstrated few sex differences across indices. There were no differences in the proportion of comorbid psychiatric disorders or functional impairment between DSM-5 and ICD-11 criteria. ICD-11 PTSD criteria demonstrate neither greater diagnostic specificity nor reduced rates of comorbidity relative to DSM-5 criteria and, as such, do not perform as intended. Modifications to existing symptoms or new symptoms may improve differential diagnosis. © 2017 Wiley Periodicals, Inc.

Toward an electrical power utility for space exploration

Bercaw, Robert W.

1989-01-01

Plans for space exploration depend on today's technology programs addressing the novel requirements of space-based enterprise. The requirements for electrical power will be formidable: megawatts in magnitude, reliability for multi-year missions and the flexibility to adapt to needs unanticipated at design time. The reasons for considering the power management and distribution in the various systems from a total mission perspective, rather than simply extrapolating current spacecraft design practice, are discussed. A utility approach to electric power being developed at the Lewis Research Center is described. It integrates requirements from a broad selection of current development programs with studies in which both space and terrestrial technologies are conceptually applied to exploration mission scenarios.

Convergence between DSM-IV-TR and DSM-5 diagnostic models for personality disorder: evaluation of strategies for establishing diagnostic thresholds.

PubMed

Morey, Leslie C; Skodol, Andrew E

2013-05-01

The Personality and Personality Disorders Work Group for the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) recommended substantial revisions to the personality disorders (PDs) section of DSM-IV-TR, proposing a hybrid categorical-dimensional model that represented PDs as combinations of core personality dysfunctions and various configurations of maladaptive personality traits. Although the DSM-5 Task Force endorsed the proposal, the Board of Trustees of the American Psychiatric Association (APA) did not, placing the Work Group's model in DSM-5 Section III ("Emerging Measures and Models") with other concepts thought to be in need of additional research. This paper documents the impact of using this alternative model in a national sample of 337 patients as described by clinicians familiar with their cases. In particular, the analyses focus on alternative strategies considered by the Work Group for deriving decision rules, or diagnostic thresholds, with which to assign categorical diagnoses. Results demonstrate that diagnostic rules could be derived that yielded appreciable correspondence between DSM-IV-TR and proposed DSM-5 PD diagnoses-correspondence greater than that observed in the transition between DSM-III and DSM-III-R PDs. The approach also represents the most comprehensive attempt to date to provide conceptual and empirical justification for diagnostic thresholds utilized within the DSM PDs.

An Assessment Model for Energy Efficiency Program Planning in Electric Utilities: Case of the Pacific of Northwest U.S.A

NASA Astrophysics Data System (ADS)

Iskin, Ibrahim

Energy efficiency stands out with its potential to address a number of challenges that today's electric utilities face, including increasing and changing electricity demand, shrinking operating capacity, and decreasing system reliability and flexibility. Being the least cost and least risky alternative, the share of energy efficiency programs in utilities' energy portfolios has been on the rise since the 1980s, and their increasing importance is expected to continue in the future. Despite holding great promise, the ability to determine and invest in only the most promising program alternatives plays a key role in the successful use of energy efficiency as a utility-wide resource. This issue becomes even more significant considering the availability of a vast number of potential energy efficiency programs, the rapidly changing business environment, and the existence of multiple stakeholders. This dissertation introduces hierarchical decision modeling as the framework for energy efficiency program planning in electric utilities. The model focuses on the assessment of emerging energy efficiency programs and proposes to bridge the gap between technology screening and cost/benefit evaluation practices. This approach is expected to identify emerging technology alternatives which have the highest potential to pass cost/benefit ratio testing procedures and contribute to the effectiveness of decision practices in energy efficiency program planning. The model also incorporates rank order analysis and sensitivity analysis for testing the robustness of results from different stakeholder perspectives and future uncertainties in an attempt to enable more informed decision-making practices. The model was applied to the case of 13 high priority emerging energy efficiency program alternatives identified in the Pacific Northwest, U.S.A. The results of this study reveal that energy savings potential is the most important program management consideration in selecting emerging energy efficiency programs. Market dissemination potential and program development and implementation potential are the second and third most important, whereas ancillary benefits potential is the least important program management consideration. The results imply that program value considerations, comprised of energy savings potential and ancillary benefits potential; and program feasibility considerations, comprised of program development and implementation potential and market dissemination potential, have almost equal impacts on assessment of emerging energy efficiency programs. Considering the overwhelming number of value-focused studies and the few feasibility-focused studies in the literature, this finding clearly shows that feasibility-focused studies are greatly understudied. The hierarchical decision model developed in this dissertation is generalizable. Thus, other utilities or power systems can adopt the research steps employed in this study as guidelines and conduct similar assessment studies on emerging energy efficiency programs of their interest.

Objective In DSM-IV, to be diagnosed with Bulimia Nervosa (BN) or the provisional diagnosis of Binge Eating Disorder (BED), an individual must experience episodes of binge eating is “at least twice a week” on average, for three or six months respectively. The purpose of this review was to examine the validity and utility of the frequency criterion for BN and BED. Method Published studies evaluating the frequency criterion were reviewed. Results Our review found little evidence to support the validity or utility of the DSM-IV frequency criterion of twice a week binge eating; however, the number of studies available for our review was limited. Conclusion A number of options are available for the frequency criterion in DSM-V, and the optimal diagnostic threshold for binge eating remains to be determined. PMID:19610014

Testing and development of electric vehicle batteries for EPRI Electric Transportation Program

NASA Astrophysics Data System (ADS)

1985-11-01

Argonne National Laboratory conducted an electric-vehicle battery testing and development program for the Electric Power Research Institute. As part of this program, eighteen battery modules previously developed by Johnson Controls, Inc. were tested. This type of battery (EV-2300 - an improved state-of-the-art lead-acid battery) was designed specifically for improved performance, range, and life in electric vehicles. In order to obtain necessary performance data, the batteries were tested under various duty cycles typical of normal service. This program, supported by the Electric Power Research Institute, consisted of three tasks: determination of the effect of cycle life vs peak power and rest period, determination of the impact of charge method on cycle life, and evaluation of the EV-2300 battery system. Two supporting studies were also carried out: one on thermal management of electric-vehicle batteries and one on enhanced utilization of active material in lead-acid batteries.

Samsudin, A.; Suhandi, A.; Rusdiana, D.; Kaniawati, I.

2016-08-01

Interactive Conceptual Instruction (ICI) based Multimedia has been developed to represent the electric concepts turn into more real and meaningful learning. The initial design of ICI based multimedia is a multimedia computer that allows users to explore the entire electric concepts in terms of the existing conceptual and practical. Pre-service physics teachers should be provided with the learning that could optimize the conceptions held by re-conceptualizing concepts in Basic Physics II, especially the concepts about electricity. To collect and to analyze the data genuinely and comprehensively, researchers utilized a developing method of ADDIE which has comprehensive steps: analyzing, design, development, implementation, and evaluation. The ADDIE developing steps has been utilized to describe comprehensively from the phase of analysis program up until the evaluation program. Based on data analysis, it can be concluded that ICI-based multimedia could effectively increase the pre-service physics teachers’ understanding on electric conceptions for re-conceptualizing electric conceptions at Universitas Pendidikan Indonesia.

Objective Existing measures for DSM-IV eating disorder diagnoses have notable limitations, and there are important differences between DSM-IV and DSM-5 feeding and eating disorders. This study developed and validated a new semi-structured interview, the Eating Disorders Assessment for DSM-5 (EDA-5). Method Two studies evaluated the utility of the EDA-5. Study 1 compared the diagnostic validity of the EDA-5 to the Eating Disorder Examination (EDE) and evaluated the test-retest reliability of the new measure. Study 2 compared the diagnostic validity of an EDA-5 electronic application (“app”) to clinician interview and self-report assessments. Results In Study 1, the kappa for EDE and EDA-5 eating disorder diagnoses was 0.74 across all diagnoses (n= 64), with a range of κ=0.65 for Other Specified Feeding or Eating Disorder (OSFED)/Unspecified Feeding or Eating Disorder (USFED) to κ=0.90 for Binge Eating Disorder (BED). The EDA-5 test-retest kappa coefficient was 0.87 across diagnoses. For Study 2, clinical interview versus “app” conditions revealed a kappa of 0.83 for all eating disorder diagnoses (n=71). Across individual diagnostic categories, kappas ranged from 0.56 for OSFED/USFED to 0.94 for BN. Discussion High rates of agreement were found between diagnoses by EDA-5 and the EDE, and EDA-5 and clinical interviews. As this study supports the validity of the EDA-5 to generate DSM-5 eating disorders and the reliability of these diagnoses, the EDA-5 may be an option for the assessment of Anorexia Nervosa, Bulimia Nervosa, and BED. Additional research is needed to evaluate the utility of the EDA-5 in assessing DSM-5 feeding disorders. PMID:25639562

The Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) contains criteria for psychiatric diagnoses that reflect advances in the science and conceptualization of mental disorders and address the needs of clinicians. DSM-5 also recommends research on dimensional measures of cross-cutting symptoms and diagnostic severity, which are expected to better capture patients’ experiences with mental disorders. Prior to its May 2013 release, the American Psychiatric Association (APA) conducted field trials to examine the feasibility, clinical utility, reliability, and where possible, the validity of proposed DSM-5 diagnostic criteria and dimensional measures. The methods and measures proposed for the DSM-5 field trials were pilot tested in adult and child/adolescent clinical samples, with the goal to identify and correct design and procedural problems with the proposed methods before resources were expended for the larger DSM-5 Field Trials. Results allowed for the refinement of the protocols, procedures, and measures, which facilitated recruitment, implementation, and completion of the DSM-5 Field Trials. These results highlight the benefits of pilot studies in planning large multisite studies. PMID:24615761

This study aimed (1) to describe frequencies of DSM IV somatisation disorder, undifferentiated somatoform disorder and pain disorder versus DSM 5 somatic symptom disorder (SSD) in a multi-setting population of patients with medically unexplained physical symptoms (MUPS), (2) to investigate differences in sociodemographic and (psycho)pathological characteristics between these diagnostic groups and (3) to explore the clinical relevance of the distinction between mild and moderate DSM 5 SSD. We used baseline data of a cohort of 325 MUPS patients. Measurements included questionnaires about symptom severity, physical functioning, anxiety, depression, health anxiety and illness perceptions. These questionnaires were used as proxy measures for operationalization of DSM IV and DSM 5 diagnostic criteria. 92.9% of participants fulfilled criteria of a DSM IV somatoform disorder, while 45.5% fulfilled criteria of DSM 5 SSD. Participants fulfilling criteria of DSM 5 SSD suffered from more severe symptoms than those only fulfilling criteria of a DSM IV somatoform disorder(mean PHQ-15 score of 13.98 (SD 5.17) versus 11.23 (SD 4.71), P-value<0.001). Furthermore their level of physical functioning was significantly lower. Compared to patients with mild SSD, patients with moderate SSD suffered from significantly lower physical functioning and higher levels of depression. Within a population of MUPS patients DSM 5 SSD criteria are more restrictive than DSM IV criteria for somatoform disorders. They are associated with higher symptom severity and lower physical functioning. However, further specification of the positive psychological criteria of DSM 5 SSD may improve utility in research and practice. Copyright © 2016 Elsevier Inc. All rights reserved.

Antisocial personality disorder in DSM-5: missteps and missed opportunities.

Lynam, Donald R; Vachon, David D

2012-10-01

This paper evaluates the proposal for antisocial personality disorder (ASPD) in the Diagnostic and Statistical Manual of Mental Disorders-fifth edition (DSM-5). Some aspects of the proposal are appealing: personality disorders will be assessed using trait criteria, and these criteria are similar to trait descriptions of DSM-IV ASPD. Other aspects of the proposal are less appealing. First, the DSM-5 will depend on a newly constructed personality trait system rather than relying on a well validated, widely studied one. Second, the trait profile of ASPD is incomplete; although this profile reflects the traits included in DSM-IV, it maps poorly onto the full personality profile of ASPD. Third, the DSM Workgroup missed an opportunity to finally unify ASPD and psychopathy; history and research suggest that these disorders have diverged mistakenly. Fourth, the newly proposed criteria of impairments in self- and interpersonal functioning are of questionable derivation and utility. (PsycINFO Database Record (c) 2012 APA, all rights reserved).

Synthesizing dimensional and categorical approaches to personality disorders: refining the research agenda for DSM-V Axis II.

Personality disorder researchers have long considered the utility of dimensional approaches to diagnosis, signaling the need to consider a dimensional approach for personality disorders in the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-V). Nevertheless, a dimensional approach to personality disorders in DSM-V is more likely to succeed if it represents an orderly and logical progression from the categorical system in DSM-IV. With these considerations and opportunities in mind, the authors sought to delineate ways of synthesizing categorical and dimensional approaches to personality disorders that could inform the construction of DSM-V. This discussion resulted in (1) the idea of having a set of core descriptive elements of personality for DSM-V, (2) an approach to rating those elements for specific patients, (3) a way of combining those elements into personality disorder prototypes, and (4) a revised conception of personality disorder as a construct separate from personality traits.

Objective: To evaluate the effectiveness of specific self-report questionnaires in detecting DSM-5 eating disorders identified via structured clinical interview in a weight-loss treatment–seeking obese sample, to improve eating disorder recognition in general clinical settings. Method: Individuals were recruited over a 3-month period (November 2, 2011, to January 10, 2012) when initially presenting to a hospital-based weight-management center in the northeastern United States, which offers evaluation and treatment for outpatients who are overweight or obese. Participants (N = 100) completed the Structured Clinical Interview for DSM-IV eating disorder module, a DSM-5 feeding and eating disorders interview, and a battery of self-report questionnaires. Results: Self-reports and interviews agreed substantially in the identification of bulimia nervosa (DSM-IV and DSM-5: tau-b = 0.71, P < .001) and binge-eating disorder (DSM-IV and DSM-5: tau-b = 0.60, P < .001), modestly for subthreshold binge-eating disorder (tau-b = 0.44, P < .001), and poorly for other subthreshold conditions (night-eating syndrome: tau-b = –0.04, P = .72, r = 0.06 [DSM-5]). Discussion: Current self-report assessments are likely to identify full syndrome DSM-5 eating disorders in treatment-seeking obese samples, but unlikely to detect DSM-5 other specified feeding or eating disorders. We propose specific content changes that might enhance clinical utility as suggestions for future evaluation. PMID:25667810

The Spanish Association of Electric Utilities (UNESA) and the state-owned industrial holding company (INI) have undertaken a 5-year program for the more efficient utilization of energy through solar energy and other energy conserving technologies. Among the tasks undertaken was the design of a solar collector particularly well suited to Spanish conditions. More than 28,000 m/sup 2/ of this collector have been installed, accounting for 42% of the Spanish market over the past three years. In cooperation with the Franklin Research Center of Philadelphia, PA, the UNESA-INI staff has carried out a binational program of solar energy utilization, funded under themore » U.S. -Spanish Treaty of Friendship and Cooperation. As a part of this program, five demonstration projects have been constructed or are under construction. Four of them provide space heating and cooling and service water heating by means of evacuated tube collectors, EPDM collectors, air heating collectors, a water-to-water heat pump, and an absorption chiller; a fifth generates electricity by means of photovoltaic cells.« less

Natural gas-fired heat pumps (GHP's), an emerging technology, may offer environmental economic, and energy benefits relative to standard and advanced space conditioning equipment now on the market. This paper describes an analysis of GHP's for residential space heating, and cooling relative to major competing technologies under an Integrated Resource (IRP) framework. Our study models a hypothetical GHP rebate program using conditions typical of the Great Lakes region. The analysis is performed for a base scenario with sensitivity cases. In the base scenario, the GHP program is cost-effective according to the societal test, total resource cost test (TRC), and the participant test, but is not cost-effective according to the non-participant test. The sensitivity analyses indicate that the results for the TRC test are most sensitive to the season in which electric demand peaks and the technology against which the GHP's are competing, and are less sensitive to changes in the marginal administrative costs. The modeled GHP program would save 900 million kWh over the life of the program and reduce peak load by about 100 MW in winter and about 135 MW in summer. We estimate all of the GHP's in service (both GHP's of program participants and nonparticipants) in the case study region would save 1,900 million kWh and reduce summer peak load by over 350 MW.

Personality disorders are associated with fundamental disturbances of self and interpersonal relations, problems that vary in severity within and across disorders. This review surveyed clinician-rated measures of personality psychopathology that focus on self-other dimensions to explore the feasibility and utility of constructing a scale of severity of impairment in personality functioning for DSM-5. Robust elements of the instruments were considered in creating a continuum of personality functioning based on aspects of identity, self-direction, empathy, and intimacy. Building on preliminary findings (Morey et al., 2011 /this issue), the proposed Levels of Personality Functioning will be subjected to extensive empirical testing in the DSM-5 field trials and elsewhere. The resulting version of this severity measure is expected to have clinical utility in identifying personality psychopathology, planning treatment, building the therapeutic alliance, and studying treatment course and outcome.

DSM-IV: a nosology sold before its time?

The purpose of this study was to determine whether American psychiatrists believe that DSM-IV is being published too soon after DSM-III-R. The authors conducted a mail survey of the attitudes of practicing psychiatrists (N = 454), residency program directors (N = 128), residents (N = 1,331), and researchers (N = 196) toward the scheduled publication of DSM-IV in the early 1990s. They found that the majority of all four groups believed that DSM-IV is being published prematurely. In contrast to respondents who believed that the timing of DSM-IV is appropriate, those who indicated that it is being published too soon had more recently completed their residency training and also believed that DSM-III-R was published prematurely. There was no association between the psychiatrists' responses and their theoretical orientation, Board certification status, ownership of the DSM manuals, the length of time they had used DSM-III, and the diagnostic manual (DSM-III or DSM-III-R) they were currently using. The belief that DSM-IV is being published too soon could contribute to underuse of DSM-IV by substantial numbers of psychiatrists. Thus, to foster compliance with it, APA must preserve in its efforts to demonstrate that the advantages of publishing it in 1993 outweigh the disadvantages of adopting yet another manual.

Convergent, discriminant, and criterion validity of DSM-5 traits.

Yalch, Matthew M; Hopwood, Christopher J

2016-10-01

Section III of the Diagnostic and Statistical Manual of Mental Disorders (5th edi.; DSM-5; American Psychiatric Association, 2013) contains a system for diagnosing personality disorder based in part on assessing 25 maladaptive traits. Initial research suggests that this aspect of the system improves the validity and clinical utility of the Section II Model. The Computer Adaptive Test of Personality Disorder (CAT-PD; Simms et al., 2011) contains many similar traits as the DSM-5, as well as several additional traits seemingly not covered in the DSM-5. In this study we evaluate the convergent and discriminant validity between the DSM-5 traits, as assessed by the Personality Inventory for DSM-5 (PID-5; Krueger et al., 2012), and CAT-PD in an undergraduate sample, and test whether traits included in the CAT-PD but not the DSM-5 provide incremental validity in association with clinically relevant criterion variables. Results supported the convergent and discriminant validity of the PID-5 and CAT-PD scales in their assessment of 23 out of 25 DSM-5 traits. DSM-5 traits were consistently associated with 11 criterion variables, despite our having intentionally selected clinically relevant criterion constructs not directly assessed by DSM-5 traits. However, the additional CAT-PD traits provided incremental information above and beyond the DSM-5 traits for all criterion variables examined. These findings support the validity of pathological trait models in general and the DSM-5 and CAT-PD models in particular, while also suggesting that the CAT-PD may include additional traits for consideration in future iterations of the DSM-5 system.

This paper studies the discriminative capacity of CBCL/1½-5 (Manual for the ASEBA Preschool-Age Forms & Profiles, University of Vermont, Research Center for Children, Youth, & Families, Burlington, 2000) DSM5 scales attention deficit and hyperactivity disorder (ADHD), oppositional defiant disorder (ODD), anxiety and depressive problems for detecting the presence of DSM5 (DSM5 diagnostic and statistical manual of mental disorders, APA, Arlington, 2013) disorders, ADHD, ODD, Anxiety and Mood disorders, assessed through diagnostic interview, in children aged 3-5. Additionally, we compare the clinical utility of the CBCL/1½-5-DSM5 scales with respect to analogous CBCL/1½-5 syndrome scales. A large community sample of 616 preschool children was longitudinally assessed for the stated age group. Statistical analysis was based on ROC procedures and binary logistic regressions. ADHD and ODD CBCL/1½-5-DSM5 scales achieved good discriminative ability to identify ADHD and ODD interview's diagnoses, at any age. CBCL/1½-5-DSM5 Anxiety scale discriminative capacity was fair for unspecific anxiety disorders in all age groups. CBCL/1½-5-DSM5 depressive problems' scale showed the poorest discriminative capacity for mood disorders (including depressive episode with insufficient symptoms), oscillating into the poor-to-fair range. As a whole, DSM5-oriented scales generally did not provide evidence better for discriminative capacity than syndrome scales in identifying DSM5 diagnoses. CBCL/1½-5-DSM5 scales discriminate externalizing disorders better than internalizing disorders for ages 3-5. Scores on the ADHD and ODD CBCL/1½-5-DSM5 scales can be used to screen for DSM5 ADHD and ODD disorders in general populations of preschool children.

In analyzing data from the National Database for Autism Research, we utilized Mokken scaling techniques as a means of creating a more effective and efficient screening procedure for autism spectrum disorder (ASD) via the Social Communication Questionnaire (SCQ). With a sample of 1,040, approximately 80% (n = 827) of the sample were males while approximately 20% (n = 213) were females. In regard to ethnicity, approximately 68% of the sample were White/Caucasian, while 7% were African American, 16% were Hispanic, 4% were Asian, and 1% were Native American or American Indian. As the Diagnostic and Statistical Manual of Mental Disorders (5th ed.; DSM-5) states that, "individuals with a well-established DSM-IV diagnosis of autistic disorder, Asperger's disorder, or pervasive developmental disorder not otherwise specified should be given the diagnosis of autism spectrum disorder," (American Psychiatric Association, 2013, p. 51), the primary labeling difference between the DSM-IV and the DSM-5 would appear to be in identifying social communication disorder as a newly introduced disorder in the DSM-5, which we discuss. Though school psychologists are not dependent on the DSM to the same extent as clinical psychologists to provide services, school psychology is invested in the effective and efficient assessment of ASD. The current study demonstrates how Mokken scaling procedures may be utilized with respect to ASD identification via the SCQ as well as providing information regarding the prevalence of potential social communication disorder as a new disorder and its discrimination with ASD.

The TRPM4 channel is a Ca2+-activated, monovalent cation-selective channel of the melastatin transient receptor potential (TRPM) family. The TRPM4 channel is implicated in the regulation of many cellular processes including the immune response, insulin secretion, and pressure-induced vasoconstriction of cerebral arteries. However, the expression and function of the TRPM4 channels in detrusor smooth muscle (DSM) have not yet been explored. Here, we provide the first molecular, electrophysiological, and functional evidence for the presence of TRPM4 channels in rat DSM. We detected the expression of TRPM4 channels at mRNA and protein levels in freshly isolated DSM single cells and DSM tissue using RT-PCR, Western blotting, immunohistochemistry, and immunocytochemistry. 9-Hydroxyphenanthrene (9-phenanthrol), a novel selective inhibitor of TRPM4 channels, was used to examine their role in DSM function. In perforated patch-clamp recordings using freshly isolated rat DSM cells, 9-phenanthrol (30 μM) decreased the spontaneous inward current activity at −70 mV. Real-time DSM live-cell Ca2+ imaging showed that selective inhibition of TRPM4 channels with 9-phenanthrol (30 μM) significantly reduced the intracellular Ca2+ levels. Isometric DSM tension recordings revealed that 9-phenanthrol (0.1–30 μM) significantly inhibited the amplitude, muscle force integral, and frequency of the spontaneous phasic and pharmacologically induced contractions of rat DSM isolated strips. 9-Phenanthrol also decreased the amplitude and muscle force integral of electrical field stimulation-induced contractions. In conclusion, this is the first study to examine the expression and provide evidence for TRPM4 channels as critical regulators of rat DSM excitability and contractility. PMID:23283997

The Nature Conservancy is an international organization dedicated to the mission of conserving biodiversity throughout the world. By working in a nonconfrontational manner, an approach that has promoted both government and corporate sponsorship of its activities, The Nature Conservancy has developed symbiotic relationships with many electric utility companies. Drawing on the organization's experiences, and the experiences of the author as the President and Chief Executive Officer of The Nature Conservancy, five broad areas of cooperation between conservation organizations and the utility industry are explored: landmanagement agreements, mitigation projects, conflictavoidance programs, program support, and volunteer activities. The paper is concluded with comments on the future trends of biodiversity conservation, challenging the electric utility industry to become involved with conservation efforts by forming cooperative partnerships.

Estimating potential stranded commitments for U.S. investor-owned electric utilities

DOE Office of Scientific and Technical Information (OSTI.GOV)

Baxter, L.; Hirst, E.

New technologies, low natural gas prices, and federal and state utility regions are restructuring the electricity industry. Yesterday`s vertically integrated utility with a retail monopoly franchise may be a very different organization in a few years. Conferences, regulatory-commission hearings, and other industry fora are dominated by debates over the extent and form of utility deintegration, wholesale competition, and retail wheeling. A key obstacle to restructuring the electricity industry is stranded commitments. Past investments, power-purchase contracts, and public-policy-driven programs that made sense in an era of cost-of-service regulation may not be cost-effective in a competitive power market. Regulators, utilities, and othermore » parties face tough decisions concerning the mitigation and allocation of these stranded commitments. The authors developed and applied a simple method to calculate the amount of stranded commitments facing US investor-owned electric utilities. The results obtained with this method depend strongly on a few key assumptions: (1) the fraction of utility sales that is at risk with respect to competition, (2) the market price of electric generation, and (3) the number of years during which the utility would lose money because of differences between its embedded cost of production and the market price.« less

Do β3-adrenergic receptors play a role in guinea pig detrusor smooth muscle excitability and contractility?

PubMed Central

Afeli, Serge A. Y.; Hristov, Kiril L.

2012-01-01

In many species, β3-adrenergic receptors (β3-ARs) have been reported to play a primary role in pharmacologically induced detrusor smooth muscle (DSM) relaxation. However, their role in guinea pig DSM remains controversial. The aim of this study was to investigate whether β3-ARs are expressed in guinea pig DSM and to evaluate how BRL37344 and L-755,507, two selective β3-AR agonists, modulate guinea pig DSM excitability and contractility. We used a combined experimental approach including RT-PCR, patch-clamp electrophysiology, and isometric DSM tension recordings. β3-AR mRNA message was detected in freshly isolated guinea pig DSM single cells. BRL37344 but not L-755,507 caused a slight decrease in DSM spontaneous phasic contraction amplitude and frequency in a concentration-dependent manner. In the presence of atropine (1 μM), only the spontaneous phasic contractions frequency was inhibited by BRL37344 at higher concentrations. Both BRL37344 and L-755,507 significantly decreased DSM carbachol-induced phasic and tonic contractions in a concentration-dependent manner. However, only BRL37344 inhibitory effect was partially antagonized by SR59230A (10 μM), a β3-AR antagonist. In the presence of atropine, BRL37344 and L-755,507 had no inhibitory effect on electrical field stimulation-induced contractions. Patch-clamp experiments showed that BRL37344 (100 μM) did not affect the DSM cell resting membrane potential and K+ conductance. Although β3-ARs are expressed at the mRNA level, they play a minor to no role in guinea pig DSM spontaneous contractility without affecting cell excitability. However, BRL37344 and L-755,507 have pronounced inhibitory effects on guinea pig DSM carbachol-induced contractions. The study outlines important DSM β3-ARs species differences. PMID:21993887

Voltage-gated Kv7 (KCNQ) channels are emerging as essential regulators of smooth muscle excitability and contractility. However, their physiological role in detrusor smooth muscle (DSM) remains to be elucidated. Here, we explored the molecular expression and function of Kv7 channel subtypes in guinea pig DSM by RT-PCR, qRT-PCR, immunohistochemistry, electrophysiology, and isometric tension recordings. In whole DSM tissue, mRNAs for all Kv7 channel subtypes were detected in a rank order: Kv7.1~Kv7.2Kv7.3~Kv7.5Kv7.4. In contrast, freshly-isolated DSM cells showed mRNA expression of: Kv7.1~Kv7.2Kv7.5Kv7.3~Kv7.4. Immunohistochemical confocal microscopy analyses of DSM, conducted by using co-labeling of Kv7 channel subtype-specific antibodies and α-smooth muscle actin, detected protein expression for all Kv7 channel subtypes, except for the Kv7.4, in DSM cells. L-364373 (R-L3), a Kv7.1 channel activator, and retigabine, a Kv7.2-7.5 channel activator, inhibited spontaneous phasic contractions and the 10-Hz electrical field stimulation (EFS)-induced contractions of DSM isolated strips. Linopiridine and XE991, two pan-Kv7 (effective at Kv7.1-Kv7.5 subtypes) channel inhibitors, had opposite effects increasing DSM spontaneous phasic and 10 Hz EFS-induced contractions. EFS-induced DSM contractions generated by a wide range of stimulation frequencies were decreased by L-364373 (10 µM) or retigabine (10 µM), and increased by XE991 (10 µM). Retigabine (10 µM) induced hyperpolarization and inhibited spontaneous action potentials in freshly-isolated DSM cells. In summary, Kv7 channel subtypes are expressed at mRNA and protein levels in guinea pig DSM cells. Their pharmacological modulation can control DSM contractility and excitability; therefore, Kv7 channel subtypes provide potential novel therapeutic targets for urinary bladder dysfunction.

Background: Home hemodialysis is associated with lower costs to the health care system compared with conventional facility-based hemodialysis because of lower staffing and overhead costs, and by transferring the treatment cost of utilities (water and power) to the patient. The purpose of this study was to determine the utility costs of home hemodialysis and create a formula such that patients and renal programs can estimate the annual patient-borne costs involved with this type of treatment. Methods: Seven common combinations of treatment duration and dialysate flows were replicated 5 times using various combinations of home hemodialysis and reverse osmosis machines. Real-time utility (electricity and water) consumption was monitored during these simulations. A generic formula was developed to allow patients and programs to calculate a more precise estimate of utility costs based on individual combinations of dialysis intensity, frequency and utility costs unique to any patient. Results: Using typical 2014 utility costs for Edmonton, the most expensive prescription was for nocturnal home hemodialysis (8 h at 300 mL/min, 6 d/wk), which resulted in a utility cost of $1269 per year; the least expensive prescription was for conventional home hemodialysis (4 h at 500 mL/min, 3 d/wk), which cost $420 per year. Water consumption makes up most of this expense, with electricity accounting for only 12% of the cost. Interpretation: We show that a substantial cost burden is transferred to the patient on home hemodialysis, which would otherwise be borne by the renal program. PMID:28401120

2017-01-01

The role of theoretical orientation in determining preference for different methods of diagnosis has been largely unexplored. The goal of the present study was to explore ratings of the usefulness of 4 diagnostic methods after applying them to a patient: prototype ratings derived from the SWAP-II, the DSM-5 Section III specific personality disorders, the DSM-5 Section III trait model, and prototype ratings derived from the Psychodynamic Diagnostic Manual (PDM). Three hundred and twenty-nine trainees in APA-accredited doctoral programs and internships rated one of their current patients with each of the 4 diagnostic methods. Individuals who classified their theoretical orientation as "cognitive- behavioral" displayed a significantly greater preference for the proposed DSM-5 personality disorder prototypes when compared to individuals who classified their orientation as "psychodynamic/psychoanalytic," while individuals who considered themselves psychodynamic or psychoanalytic rated the PDM as significantly more useful than those who considered themselves cognitive-behavioral. Individuals who classified their graduate program as a PsyD program were also more likely to rate the DSM-5 Section III and PDM models as more useful diagnostic methods than individuals who classified their graduate program as a PhD program. Implications and future directions will be discussed. © 2017 S. Karger AG, Basel.

The aim of the study was to compare the DSM-IV, DSM-5, and ICD-10 eating disorders (ED) nomenclatures to assess their value in the classification of pediatric eating disorders. We investigated the prevalence of the disorders in accordance with each system's diagnostic criteria, diagnostic concordance between the systems, and interrater reliability. Participants were 1062 children and adolescents assessed at intake to a specialist Eating Disorders Program (91.6% female, mean age 14.5 years, SD = 1.75). Measures were collected from routine intake assessments. DSM-5 categorization led to a lower prevalence of unspecified EDs when compared with DSM-IV. There was almost complete overlap for specified EDs. Kappa values indicated almost excellent agreement between the two coders on all three diagnostic systems, although there was higher interrater reliability for DSM-5 and ICD-10 when compared with DSM-IV. DSM-5 nomenclature is useful in classifying eating disorders in pediatric clinical samples. © 2018 Wiley Periodicals, Inc.

Section 3 of the DSM-5 will include a pathological personality trait system rooted in the quantitative epistemology of personality and clinical psychology. This system has the potential to enhance the clinical utility of the diagnostic nosology by providing a means for the dimensional assessment of individuals with psychopathology. However, there is limited research on the associations of DSM-5 traits with common mental disorders and related clinical phenomena as measured by currently popular assessment instruments. The purpose of this article was to evaluate the convergence of the DSM-5 trait system with a well-validated broadband clinical instrument, the Personality Assessment Inventory (PAI). Bivariate correlations were examined and factor analytic methods were used to examine the degree to which the DSM-5 traits and PAI capture common variance in personality and mental health. In a student sample (N = 1,001), we found broad convergence between the DSM-5 traits and PAI, which could be organized effectively using five factors. The implications of these findings for using traits to address issues related to diagnostic co-occurrence and heterogeneity in routine clinical assessment are discussed.

Contributions from personality- and psychodynamically oriented assessment to the development of the DSM-5 personality disorders.

2011-07-01

Advances in personality assessment over the past 20 years have notably influenced the proposed assessment and classification of personality disorders in the Diagnostic and Statistical Manual of Mental Disorders (5th ed. [DSM-5]). However, a considerable body of personality assessment and psychodynamically oriented assessment research has significant relevance to the way in which personality disorders are evaluated that appears to have gone unrecognized in the current proposals for DSM-5. In this article, I discuss the ways in which some of these 2 bodies of literature can and should inform the DSM-5 so that the diagnostic nomenclature can be more scientifically and comprehensively informed and consequently improve the clinical utility of a diagnostic system in need of considerable revision.

BK Channel-Mediated Relaxation of Urinary Bladder Smooth Muscle: A Novel Paradigm for Phosphodiesterase Type 4 Regulation of Bladder Function

PubMed Central

Xin, Wenkuan; Li, Ning; Cheng, Qiuping

2014-01-01

Elevation of intracellular cAMP and activation of protein kinase A (PKA) lead to activation of large conductance voltage- and Ca2+-activated K+ (BK) channels, thus attenuation of detrusor smooth muscle (DSM) contractility. In this study, we investigated the mechanism by which pharmacological inhibition of cAMP-specific phosphodiesterase 4 (PDE4) with rolipram or Ro-20-1724 (C15H22N2O3) suppresses guinea pig DSM excitability and contractility. We used high-speed line-scanning confocal microscopy, ratiometric fluorescence Ca2+ imaging, and perforated whole-cell patch-clamp techniques on freshly isolated DSM cells, along with isometric tension recordings of DSM isolated strips. Rolipram caused an increase in the frequency of Ca2+ sparks and the spontaneous transient BK currents (TBKCs), hyperpolarized the cell membrane potential (MP), and decreased the intracellular Ca2+ levels. Blocking BK channels with paxilline reversed the hyperpolarizing effect of rolipram and depolarized the MP back to the control levels. In the presence of H-89 [N-[2-[[3-(4-bromophenyl)-2-propenyl]amino]ethyl]-5-isoquinolinesulfonamide dihydrochloride], a PKA inhibitor, rolipram did not cause MP hyperpolarization. Rolipram or Ro-20-1724 reduced DSM spontaneous and carbachol-induced phasic contraction amplitude, muscle force, duration, and frequency, and electrical field stimulation-induced contraction amplitude, muscle force, and tone. Paxilline recovered DSM contractility, which was suppressed by pretreatment with PDE4 inhibitors. Rolipram had reduced inhibitory effects on DSM contractility in DSM strips pretreated with paxilline. This study revealed a novel cellular mechanism whereby pharmacological inhibition of PDE4 leads to suppression of guinea pig DSM contractility by increasing the frequency of Ca2+ sparks and the functionally coupled TBKCs, consequently hyperpolarizing DSM cell MP. Collectively, this decreases the global intracellular Ca2+ levels and DSM contractility in a BK channel-dependent manner. PMID:24459245

Recent developments in psychometrics enable the application of network models to analyze psychological disorders, such as PTSD. Instead of understanding symptoms as indicators of an underlying common cause, this approach suggests symptoms co-occur in syndromes due to causal interactions. The current study has two goals: (1) examine the network structure among the 20 DSM-5 PTSD symptoms, and (2) incorporate clinically relevant variables to the network to investigate whether PTSD symptoms exhibit differential relationships with suicidal ideation, depression, anxiety, physical functioning/quality of life (QoL), mental functioning/QoL, age, and sex. We utilized a nationally representative U.S. military veteran's sample; and analyzed the data from a subsample of 221 veterans who reported clinically significant DSM-5 PTSD symptoms. Networks were estimated using state-of-the-art regularized partial correlation models. Data and code are published along with the paper. The 20-item DSM-5 PTSD network revealed that symptoms were positively connected within the network. Especially strong connections emerged between nightmares and flashbacks; blame of self or others and negative trauma-related emotions, detachment and restricted affect; and hypervigilance and exaggerated startle response. The most central symptoms were negative trauma-related emotions, flashbacks, detachment, and physiological cue reactivity. Incorporation of clinically relevant covariates into the network revealed paths between self-destructive behavior and suicidal ideation; concentration difficulties and anxiety, depression, and mental QoL; and depression and restricted affect. These results demonstrate the utility of a network approach in modeling the structure of DSM-5 PTSD symptoms, and suggest differential associations between specific DSM-5 PTSD symptoms and clinical outcomes in trauma survivors. Implications of these results for informing the assessment and treatment of this disorder, are discussed. Copyright © 2016 Elsevier Ltd. All rights reserved.

With the introduction of insomnia disorder in Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5), greater emphasis has been placed on the diagnosis and treatment of sleep disorder even in the presence of a coexisting mental disorder. The current study seeks to explore the clinical picture of insomnia in the context of psychiatric disorders commonly associated with sleep complaints by assessing the prevalence and correlates of DSM-5 insomnia disorder, and examining the extent to which insomnia symptoms have been addressed in this population. Four hundred treatment-seeking outpatients suffering from depressive, bipolar affective, anxiety, and schizophrenia spectrum disorders were recruited. DSM-5 insomnia was established using the modified Brief Insomnia Questionnaire. Differences in sociodemographic factors, clinical status, impairment outcomes, and mental health services utilization were compared. Information on patients' help-seeking experiences for insomnia-related symptoms was collected to determine the treatment received and treatment effectiveness. Almost one-third of our sample (31.8%) had DSM-5 insomnia disorder. Those with insomnia disorder had significantly higher impairment outcomes than their counterparts but no group difference was observed for mental health services utilization. Findings based on past treatment contact for sleep problems suggest that diagnosis and treatment of insomnia is lacking in this population. With the new calling from DSM-5, clinicians treating psychiatric patients should view insomnia less as a symptom of their mental illnesses and treat clinical insomnia as a primary disorder. Patients should also be educated on the importance of reporting and treating their sleep complaints. Nonmedical (cognitive and behavioral) interventions for insomnia need to be further explored given their proven clinical effectiveness. © 2018 American Academy of Sleep Medicine

Very few cultivated microorganisms can degrade lignocellulosic biomass without chemical pretreatment. We show here that “Anaerocellum thermophilum” DSM 6725, an anaerobic bacterium that grows optimally at 75°C, efficiently utilizes various types of untreated plant biomass, as well as crystalline cellulose and xylan. These include hardwoods such as poplar, low-lignin grasses such as napier and Bermuda grasses, and high-lignin grasses such as switchgrass. The organism did not utilize only the soluble fraction of the untreated biomass, since insoluble plant biomass (as well as cellulose and xylan) obtained after washing at 75°C for 18 h also served as a growth substrate. The predominant end products from all growth substrates were hydrogen, acetate, and lactate. Glucose and cellobiose (on crystalline cellulose) and xylose and xylobiose (on xylan) also accumulated in the growth media during growth on the defined substrates but not during growth on the plant biomass. A. thermophilum DSM 6725 grew well on first- and second-spent biomass derived from poplar and switchgrass, where spent biomass is defined as the insoluble growth substrate recovered after the organism has reached late stationary phase. No evidence was found for the direct attachment of A. thermophilum DSM 6725 to the plant biomass. This organism differs from the closely related strain A. thermophilum Z-1320 in its ability to grow on xylose and pectin. Caldicellulosiruptor saccharolyticus DSM 8903 (optimum growth temperature, 70°C), a close relative of A. thermophilum DSM 6725, grew well on switchgrass but not on poplar, indicating a significant difference in the biomass-degrading abilities of these two otherwise very similar organisms.

Members of the transient receptor potential (TRP) channel superfamily, including the Ca2+-activated monovalent cation-selective TRP melastatin 4 (TRPM4) channel, have been recently identified in the urinary bladder. However, their expression and function at the level of detrusor smooth muscle (DSM) remain largely unexplored. In this study, for the first time we investigated the role of TRPM4 channels in guinea pig DSM excitation-contraction coupling using a multidisciplinary approach encompassing protein detection, electrophysiology, live-cell Ca2+ imaging, DSM contractility, and 9-phenanthrol, a recently characterized selective inhibitor of the TRPM4 channel. Western blot and immunocytochemistry experiments demonstrated the expression of the TRPM4 channel in whole DSM tissue and freshly isolated DSM cells with specific localization on the plasma membrane. Perforated whole cell patch-clamp recordings and real-time Ca2+ imaging experiments with fura 2-AM, both using freshly isolated DSM cells, revealed that 9-phenanthrol (30 μM) significantly reduced the cation current and decreased intracellular Ca2+ levels. 9-Phenanthrol (0.1–30 μM) significantly inhibited spontaneous, 0.1 μM carbachol-induced, 20 mM KCl-induced, and nerve-evoked contractions in guinea pig DSM-isolated strips with IC50 values of 1–7 μM and 70–80% maximum inhibition. 9-Phenanthrol also reduced nerve-evoked contraction amplitude induced by continuous repetitive electrical field stimulation of 10-Hz frequency and shifted the frequency-response curve (0.5–50 Hz) relative to the control. Collectively, our data demonstrate the novel finding that TRPM4 channels are expressed in guinea pig DSM and reveal their critical role in the regulation of guinea pig DSM excitation-contraction coupling.

Four methods of how to assess and diagnose personality disorders have received much attention within the literature: the Shedler-Westen Assessment Procedure (Shedler & Westen, 1998), the DSM-5 Section III Personality Disorders section (APA, 2011), the DSM-5 Section III trait model (APA, 2013), and the Psychodynamic Diagnostic Manual (PDM; PDM Task Force, 2006) descriptions of 15 personality disorders. Given that much of the debate has been driven by clinician concerns, it is important to consider clinical utility when evaluating the usefulness of each method. The present study compares the 4 models on ratings of several dimensions of clinical utility provided by 329 graduate student clinicians and psychology interns from across the United States. Findings suggest that participants rated the DSM-5 trait model significantly higher in most clinical utility domains. Additionally, qualitative analyses of the open-ended responses provided by participants indicated that each method had strengths and weaknesses. Most notably, participants commented positively on the PDM's level of comprehensiveness and appreciated the SWAP-II's inclusion of a health category, despite the ease of use not being as highly rated for these methods.

A Test of the Empirical Profile and Coherence of the DSM-5 Psychopathy Specifier.

2017-11-13

The Diagnostic and Statistical Manual of Mental Disorders-5th edition (DSM-5; American Psychiatric Association, 2013) introduced a psychopathy specifier (DSM-5 PS) as part of the Section III diagnostic model of antisocial personality disorder. Designed to capture the construct of fearless dominance/boldness, the DSM-5 PS is assessed on the basis of the presence of low scores on traits of withdrawal and anxiousness, and high scores on attention seeking. These constructs have garnered attention in the past decade but are the subject of substantial debate as to their role in the conceptualization and assessment of psychopathy, given their limited relations to the maladaptive outcomes typically associated with this personality disorder. In the current study (N = 340 undergraduates; 170 informants), we examined the DSM-5 PS, both in composite form and its trait subscales, to investigate the degree to which the DSM-5 PS manifested empirical profiles associated with psychopathy and its maladaptive correlates. Consistent with prior fearless dominance/boldness research, the DSM-5 PS manifested limited relations with other components of psychopathy, symptoms of DSM-5 Section II and III antisocial personality disorder, and self- and informant-related impairment scores. When examined at the individual subscale level, the 3 DSM-5 PS subscales manifested only partially overlapping profiles and only 1 of the 3-Attention Seeking-demonstrated an association with maladaptivity (e.g., externalizing behaviors). These findings raise important concerns about the coherence and utility of the DSM-5 PS as a diagnostic specifier included in a psychiatric nosology.

Background There is a need for clinical tools to identify cultural issues in diagnostic assessment. Aims To assess the feasibility, acceptability and clinical utility of the DSM-5 Cultural Formulation Interview (CFI) in routine clinical practice. Method Mixed-methods evaluation of field trial data from six countries. The CFI was administered to diagnostically diverse psychiatric out-patients during a diagnostic interview. In post-evaluation sessions, patients and clinicians completed debriefing qualitative interviews and Likert-scale questionnaires. The duration of CFI administration and the full diagnostic session were monitored. Results Mixed-methods data from 318 patients and 75 clinicians found the CFI feasible, acceptable and useful. Clinician feasibility ratings were significantly lower than patient ratings and other clinician-assessed outcomes. After administering one CFI, however, clinician feasibility ratings improved significantly and subsequent interviews required less time. Conclusions The CFI was included in DSM-5 as a feasible, acceptable and useful cultural assessment tool. © The Royal College of Psychiatrists 2017.

Taxing sulfur dioxide emission allowances

DOE Office of Scientific and Technical Information (OSTI.GOV)

Nelson, G.L.

1993-09-15

The acid rain control program authorized by Title IV of the Clean Air Act Amendments of 1990 (CAAA) was designed to reduce the adverse effects of acid rain by limiting emissions of sulfur dioxide (SO[sub 2]) into the atmosphere. The program is a complex scheme involving the issuance, consumption, holding, and trading of emission allowances for SO[sub 2]. Not surprisingly, electric utilities will face federal income tax issues in connection with the program. Under the emission allowance program, the U.S. Environmental Protection Agency (EPA) will issue emission allowance to owners or operators of certain utility power plants at no costmore » to the recipients. An emission allowance is an authorization to emit one ton of SO[sub 2] during or after the calendar year for which it is issued. If a utility power plant subject to the program emits SO[sub 2] in excess of its allowances, the owner or operator will be subject to a penalty of $2,000 a ton, and must offset the excess emissions with allowances in the subsequent year. Allowances may be bought and sold. Phase I of the program begins January 1, 1995, and will apply to 110 utility generating units. Phase II takes effect January 1, 2000, and will include most electric utility generating units. EPA will withhold a specified number of allowances for direct sale and auction. The resulting proceeds will be paid to the utilities from which the allowances were withheld.

The U.S. and Japanese amorphous silicon technology programs A comparison

NASA Technical Reports Server (NTRS)

Shimada, K.

1984-01-01

The U.S. Department of Energy/Solar Energy Research Institute Amorphous Silicon (a-Si) Solar Cell Program performs R&D on thin-film hydrogenated amorphous silicon for eventual development of stable amorphous silicon cells with 12 percent efficiency by 1988. The Amorphous Silicon Solar Cell Program in Japan is sponsored by the Sunshine Project to develop an alternate energy technology. While the objectives of both programs are to eventually develop a-Si photovoltaic modules and arrays that would produce electricity to compete with utility electricity cost, the U.S. program approach is research oriented and the Japanese is development oriented.

A sustainable development of a city electrical grid via a non-contractual Demand-Side Management

NASA Astrophysics Data System (ADS)

Samoylenko, Vladislav O.; Pazderin, Andrew V.

2017-06-01

An increasing energy consumption of large cities as well as an extreme high density of city electrical loads leads to the necessity to search for an alternative approaches to city grid development. The ongoing implementation of the energy accounting tariffs with differentiated rates depending upon the market conditions and changing in a short-term perspective, provide the possibility to use it as a financial incentive base of a Demand-Side Management (DSM). Modern hi-technology energy metering and accounting systems with a large number of functions and consumer feedback are supposed to be the good means of DSM. Existing systems of Smart Metering (SM) billing usually provide general information about consumption curve, bills and compared data, but not the advanced statistics about the correspondence of financial and electric parameters. Also, consumer feedback is usually not fully used. So, the efforts to combine the market principle, Smart Metering and a consumer feedback for an active non-contractual load control are essential. The paper presents the rating-based multi-purpose system of mathematical statistics and algorithms of DSM efficiency estimation useful for both the consumers and the energy companies. The estimation is performed by SM Data processing systems. The system is aimed for load peak shaving and load curve smoothing. It is focused primarily on a retail market support. The system contributes to the energy efficiency and a distribution process improvement by the manual management or by the automated Smart Appliances interaction.

Benefits and Costs of Aggressive Energy Efficiency Programs and the Impacts of Alternative Sources of Funding: Case Study of Massachusetts

DOE Office of Scientific and Technical Information (OSTI.GOV)

Cappers, Peter; Satchwell, Andrew; Goldman, Charles

2010-08-06

Increased interest by state (and federal) policymakers and regulatory agencies in pursuing aggressive energy efficiency efforts could deliver significant utility bill savings for customers while having long-term implications for ratepayers (e.g. potential rate impacts). Equity and distributional concerns associated with the authorized recovery of energy efficiency program costs may necessitate the pursuit of alternative program funding approaches. In 2008, Massachusetts passed the Green Communities Act which directed its energy efficiency (EE) program administrators to obtain all cost-effective EE resources. This goal has translated into achieving annual electric energy savings equivalent to a 2.4% reduction in retail sales from energy efficiencymore » programs in 2012. Representatives of electricity consumer groups supported the new portfolio of EE programs (and the projected bill savings) but raised concerns about the potential rate impacts associated with achieving such aggressive EE goals, leading policymakers to seek out alternative funding sources which can potentially mitigate these effects. Utility administrators have also raised concerns about under-recovery of fixed costs when aggressive energy efficiency programs are pursued and have proposed ratemaking policies (e.g. decoupling) and business models that better align the utility's financial interests with the state's energy efficiency public policy goals. Quantifying these concerns and identifying ways they can be addressed are crucial steps in gaining the support of major stakeholder groups - lessons that can apply to other states looking to significantly increase savings targets that can be achieved from their own ratepayer-funded energy efficiency programs. We use a pro-forma utility financial model to quantify the bill and rate impacts on electricity customers when very aggressive annual energy efficiency savings goals ({approx}2.4%) are achieved over the long-term and also assess the impact of different cost recovery approaches that integrate alternative revenue sources. We also analyze alternative lost fixed cost recovery approaches to better understand how to mitigate the erosion of utility shareholder returns in states that have adopted (and achieved) very aggressive savings targets.« less

Molecular Expression and Pharmacological Evidence for a Functional Role of Kv7 Channel Subtypes in Guinea Pig Urinary Bladder Smooth Muscle

PubMed Central

Afeli, Serge A. Y.; Malysz, John; Petkov, Georgi V.

2013-01-01

Voltage-gated Kv7 (KCNQ) channels are emerging as essential regulators of smooth muscle excitability and contractility. However, their physiological role in detrusor smooth muscle (DSM) remains to be elucidated. Here, we explored the molecular expression and function of Kv7 channel subtypes in guinea pig DSM by RT-PCR, qRT-PCR, immunohistochemistry, electrophysiology, and isometric tension recordings. In whole DSM tissue, mRNAs for all Kv7 channel subtypes were detected in a rank order: Kv7.1~Kv7.2Kv7.3~Kv7.5Kv7.4. In contrast, freshly-isolated DSM cells showed mRNA expression of: Kv7.1~Kv7.2Kv7.5Kv7.3~Kv7.4. Immunohistochemical confocal microscopy analyses of DSM, conducted by using co-labeling of Kv7 channel subtype-specific antibodies and α-smooth muscle actin, detected protein expression for all Kv7 channel subtypes, except for the Kv7.4, in DSM cells. L-364373 (R-L3), a Kv7.1 channel activator, and retigabine, a Kv7.2-7.5 channel activator, inhibited spontaneous phasic contractions and the 10-Hz electrical field stimulation (EFS)-induced contractions of DSM isolated strips. Linopiridine and XE991, two pan-Kv7 (effective at Kv7.1-Kv7.5 subtypes) channel inhibitors, had opposite effects increasing DSM spontaneous phasic and 10 Hz EFS-induced contractions. EFS-induced DSM contractions generated by a wide range of stimulation frequencies were decreased by L-364373 (10 µM) or retigabine (10 µM), and increased by XE991 (10 µM). Retigabine (10 µM) induced hyperpolarization and inhibited spontaneous action potentials in freshly-isolated DSM cells. In summary, Kv7 channel subtypes are expressed at mRNA and protein levels in guinea pig DSM cells. Their pharmacological modulation can control DSM contractility and excitability; therefore, Kv7 channel subtypes provide potential novel therapeutic targets for urinary bladder dysfunction.

Utility of DSM-5 section III personality traits in differentiating borderline personality disorder from comparison groups.

PubMed

Bach, B; Sellbom, M; Bo, S; Simonsen, E

2016-09-01

Borderline Personality Disorder (BPD) is a highly prevalent diagnosis in mental health care and includes a heterogeneous constellation of symptoms. As the field of personality disorder (PD) research moves to emphasize dimensional traits in its operationalization, it is important to determine how the alternative DSM-5 Section III personality trait dimensions differentiates such features in BPD patients versus comparison groups. To date, no study has attempted such validation. The current study examined the utility of the DSM-5 trait dimensions in differentiating patients with the categorical DSM-IV/5 diagnosis of BPD (n=101) from systematically matched samples of other PD patients (n=101) and healthy controls (n=101). This was investigated using one-way ANOVA and multinomial logistic regression analyses. Results indicated that Emotional Lability, Risk Taking, and Suspiciousness uniquely differentiated BPD patients from other PD patients, whereas Emotional Lability, Depressivity, and Suspiciousness uniquely differentiated BPD patients from healthy controls. Emotional Lability is in particular a key BPD feature of the proposed Section III model, whereas Suspiciousness also augments essential BPD features. Provided that these findings are replicated cross-culturally in forthcoming research, a more parsimonious traits operationalization of BPD features is warranted. Copyright © 2016 Elsevier Masson SAS.

Ilehag, R.; Auer, S.; d'Angelo, P.

2017-05-01

GeoRaySAR, an automated SAR simulator developed at DLR, identifies buildings in high resolution SAR data by utilizing geometric knowledge extracted from digital surface models (DSMs). Hitherto, the simulator has utilized DSMs generated from LiDAR data from airborne sensors with pre-filtered vegetation. Discarding the need for pre-optimized model input, DSMs generated from high resolution optical data (acquired with WorldView-2) are used for the extraction of building-related SAR image parts in this work. An automatic preprocessing of the DSMs has been developed for separating buildings from elevated vegetation (trees, bushes) and reducing the noise level. Based on that, automated simulations are triggered considering the properties of real SAR images. Locations in three cities, Munich, London and Istanbul, were chosen as study areas to determine advantages and limitations related to WorldView-2 DSMs as input for GeoRaySAR. Beyond, the impact of the quality of the DSM in terms of building extraction is evaluated as well as evaluation of building DSM, a DSM only containing buildings. The results indicate that building extents can be detected with DSMs from optical satellite data with various success, dependent on the quality of the DSM as well as on the SAR imaging perspective.

COMPLEAT takes its name, as an acronym, from Community-Oriented Model for Planning Least-Cost Energy Alternatives and Technologies. It is an electric utility planning model designed for use principally by publicly owned electric utilities and agencies serving such utilities. As a model, COMPLEAT is significantly more full-featured and complex than called out in APPA's original plan and proposal to DOE. The additional complexity grew out of a series of discussions early in the development schedule, in which it became clear to APPA staff and advisors that the simplicity characterizing the original plan, while highly desirable in terms of utility applications, wasmore » not achievable if practical utility problems were to be addressed. The project teams settled on Energy 20/20, an existing model developed by Dr. George Backus of Policy Assessment Associates, as the best candidate for the kinds of modifications and extensions that would be required. The remainder of the project effort was devoted to designing specific input data files, output files, and user screens and to writing and testing the compute programs that would properly implement the desired features around Energy 20/20 as a core program.

"Long life" DC brush motor for use on the Mars surveyor program

NASA Technical Reports Server (NTRS)

Braun, David; Noon, Don

1998-01-01

DC brush motors have several qualities which make them very attractive for space flight applications. Their mechanical commutation is simple and lightweight, requiring no external sensing and control in order to function properly. They are extremely efficient in converting electrical energy into mechanical energy. Efficiencies over 80% are not uncommon, resulting in high power throughput to weight ratios. However, the inherent unreliability and short life of sliding electrical contacts, especially in vacuum, have driven previous programs to utilize complex brushless DC or the less efficient stepper motors. The Mars Surveyor Program (MSP'98) and the Shuttle Radar Topography Mission (SRTM) have developed a reliable "long life" brush type DC motor for operation in low temperature, low pressure CO2 and N2, utilizing silver-graphite brushes. The original intent was to utilize this same motor for SRTM's space operation, but the results thus far have been unsatisfactory in vacuum. This paper describes the design, test, and results of this development.

Increased Activity or Energy as a Primary Criterion for the Diagnosis of Bipolar Mania in DSM-5: Findings From the STEP-BD Study.

PubMed

Machado-Vieira, Rodrigo; Luckenbaugh, David A; Ballard, Elizabeth D; Henter, Ioline D; Tohen, Mauricio; Suppes, Trisha; Zarate, Carlos A

2017-01-01

DSM-5 describes "a distinct period of abnormally and persistently elevated, expansive, or irritable mood and abnormally and persistently increased activity or energy" as a primary criterion for mania. Thus, increased energy or activity is now considered a core symptom of manic and hypomanic episodes. Using data from the Systematic Treatment Enhancement Program for Bipolar Disorder study, the authors analyzed point prevalence data obtained at the initial visit to assess the diagnostic validity of this new DSM-5 criterion. The study hypothesis was that the DSM-5 criterion would alter the prevalence of mania and/or hypomania. The authors compared prevalence, clinical characteristics, validators, and outcome in patients meeting the DSM-5 criteria (i.e., DSM-IV criteria plus the DSM-5 criterion of increased activity or energy) and those who did not meet the new DSM-5 criterion (i.e., who only met DSM-IV criteria). All 4,360 participants met DSM-IV criteria for bipolar disorder, and 310 met DSM-IV criteria for a manic or hypomanic episode. When the new DSM-5 criterion of increased activity or energy was added as a coprimary symptom, the prevalence of mania and hypomania was reduced. Although minor differences were noted in clinical and concurrent validators, no changes were observed in longitudinal outcomes. The findings confirm that including increased activity or energy as part of DSM-5 criterion A decreases the prevalence of manic and hypomanic episodes but does not affect longitudinal clinical outcomes.

The six most essential questions in psychiatric diagnosis: A pluralogue part 2: Issues of conservatism and pragmatism in psychiatric diagnosis

PubMed Central

2012-01-01

In face of the multiple controversies surrounding the DSM process in general and the development of DSM-5 in particular, we have organized a discussion around what we consider six essential questions in further work on the DSM. The six questions involve: 1) the nature of a mental disorder; 2) the definition of mental disorder; 3) the issue of whether, in the current state of psychiatric science, DSM-5 should assume a cautious, conservative posture or an assertive, transformative posture; 4) the role of pragmatic considerations in the construction of DSM-5; 5) the issue of utility of the DSM – whether DSM-III and IV have been designed more for clinicians or researchers, and how this conflict should be dealt with in the new manual; and 6) the possibility and advisability, given all the problems with DSM-III and IV, of designing a different diagnostic system. Part I of this article took up the first two questions. Part II will take up the second two questions. Question 3 deals with the question as to whether DSM-V should assume a conservative or assertive posture in making changes from DSM-IV. That question in turn breaks down into discussion of diagnoses that depend on, and aim toward, empirical, scientific validation, and diagnoses that are more value-laden and less amenable to scientific validation. Question 4 takes up the role of pragmatic consideration in a psychiatric nosology, whether the purely empirical considerations need to be tempered by considerations of practical consequence. As in Part 1 of this article, the general introduction, as well as the introductions and conclusions for the specific questions, are written by James Phillips, and the responses to commentaries are written by Allen Frances.

The process of industrialization in the Czech Republic, which is more intensive than in other parts of central Europe, has been under way since the mid-nineteenth century. Over the last 40 years, large-scale industrial activity was based on extensive use of domestic primary energy sources, especially brown-coal/lignite. The escalation of this usage inflicted heavy devastation to large portions of industrial zones and, as a result, worsened living conditions through atmospheric pollution and other environmental impacts in large regions of central Europe. The Czech electricity industry and CEZ, a.s. (the nation`s principal electricity generator, responsible for meeting eighty percent of nationalmore » electricity demand, and operator of the nationwide EHV transmission system) has been challenged to cope with all environmental issues by the end of 1997, in compliance with the strict limits set by the Clean Air Act of 1991, which are comparable to standard implemented in advanced industrial countries. A review of the critical environmental issues is presented and the role of the individual and of the State is analyzed. The approach of CEZ, a.s., towards a better natural environment and its response to legal environment provisions have been incorporated into the company`s development program. It comprises decommissioning the most obsolete fossil-fuel fired power stations; rehabilitation of thermal power plants; supplementing the coal/lignite-fired units selected for future operation with FGD systems and retrofitting them with DENOX equipment; a larger share of nuclear electricity generation after the completion of the Temelin NPP (2 units of 1000MW each) and, last but not least, initiating DSM (demand-side management) programs of energy-electricity savings in the Czech Republic.« less

Catatonia in DSM-5.

Although catatonia has historically been associated with schizophrenia and is listed as a subtype of the disorder, it can occur in patients with a primary mood disorder and in association with neurological diseases and other general medical conditions. Consequently, catatonia secondary to a general medical condition was included as a new condition and catatonia was added as an episode specifier of major mood disorders in DSM-IV. Different sets of criteria are utilized to diagnose catatonia in schizophrenia and primary mood disorders versus neurological/medical conditions in DSM-IV, however, and catatonia is a codable subtype of schizophrenia but a specifier for major mood disorders without coding. In part because of this discrepant treatment across the DSM-IV manual, catatonia is frequently not recognized by clinicians. Additionally, catatonia is known to occur in several conditions other than schizophrenia, major mood disorders, or secondary to a general medical condition. Four changes are therefore made in the treatment of catatonia in DSM-5. A single set of criteria will be utilized to diagnose catatonia across the diagnostic manual and catatonia will be a specifier for both schizophrenia and major mood disorders. Additionally, catatonia will also be a specifier for other psychotic disorders, including schizoaffective disorder, schizophreniform disorder, brief psychotic disorder, and substance-induced psychotic disorder. A new residual category of catatonia not otherwise specified will be added to allow for the rapid diagnosis and specific treatment of catatonia in severely ill patients for whom the underlying diagnosis is not immediately available. These changes should improve the consistent recognition of catatonia across the range of psychiatric disorders and facilitate its specific treatment. Published by Elsevier B.V.

The Western Area Power Administration (Western) requires all its long-term power customers to implement programs that promote the conservation of electric energy or facilitate the use of renewable energy resources. The hope is that these measures could significantly reduce the amount of environmental damage associated with electricity production. As part of preparing the environmental impact statement for Western's Electric Power Marketing Program, Argonne National Laboratory constructed a database of the conservation and renewable energy activities in which Western's Salt Lake City customers are involved. The database provides information on types of conservation and renewable energy activities and allows for comparisons of activities being conducted at different utilities in the Salt Lake City region. Sorting the database allows Western's Salt Lake City customers to be classified so the various activities offered by different classes of utilities can be identified; for example, comparisons can be made between municipal utilities and cooperatives or between large and small customers. The information included in the database was collected from customer planning documents in the files of Western's Salt Lake City office.

Strains of the genus Gramella (family Flavobacteriacae, phylum Bacteroidetes) were isolated from marine habitats such as tidal flat sediments, coastal surface seawater and sea urchins. Flavobacteriaceae have been shown to be involved in the decomposition of plant and algal polysaccharides. However, the potential to decompose polysaccharides may differ tremendously even between species of the same genus. Gramella echinicola KMM 6050 T (DSM 19838 T ) and Gramella portivictoriae UST040801-001 T (DSM 23547 T ) have genomes of similar lengths, similar numbers of protein coding genes and RNA genes.

One of the most significant changes to the section on Feeding and Eating Disorders in the DSM-5 was that feeding disorder of infancy or early childhood was renamed avoidant/restrictive food intake disorder or ARFID, and the criteria was significantly expanded. This diagnostic category was informed by field studies, analysis, and expert opinion. To date, research exploring the prevalence, clinical characteristics and utility have helped substantiate the recognition and need for the diagnostic category of AFRID as a distinct eating disorder diagnosis in the DSM-5.

Space station electrical power distribution analysis using a load flow approach

NASA Technical Reports Server (NTRS)

Emanuel, Ervin M.

1987-01-01

The space station's electrical power system will evolve and grow in a manner much similar to the present terrestrial electrical power system utilities. The initial baseline reference configuration will contain more than 50 nodes or busses, inverters, transformers, overcurrent protection devices, distribution lines, solar arrays, and/or solar dynamic power generating sources. The system is designed to manage and distribute 75 KW of power single phase or three phase at 20 KHz, and grow to a level of 300 KW steady state, and must be capable of operating at a peak of 450 KW for 5 to 10 min. In order to plan far into the future and keep pace with load growth, a load flow power system analysis approach must be developed and utilized. This method is a well known energy assessment and management tool that is widely used throughout the Electrical Power Utility Industry. The results of a comprehensive evaluation and assessment of an Electrical Distribution System Analysis Program (EDSA) is discussed. Its potential use as an analysis and design tool for the 20 KHz space station electrical power system is addressed.

This program calls attention to the upcoming timetable for the revision of the Diagnostic and Statistical Manual (DSM)-IV and the publication of DSM-V. It is vitally important for Research Society of Alcoholism members to be aware of the current discussions of the important scientific questions related to the next DSM revision and to use the opportunity for input. The title of the symposium highlights 1 key question, i.e., whether the DSM definitions should remain strictly categorical as in the past or whether a dimensional component should be included in this revision. Two substantive and 1 conceptual paper are included in this portion of the symposium. The fourth and final presentation detailing the revision timetable and the opportunities for input is by Dr. Darrel Regier. Dr. Regier is the director of American Psychiatric Institute for Research and Education the research and education branch of the American Psychiatric Association and the organization within the APA that will oversee the DSM revision. The discussion is by Marc Schuckit, who was chair of the Substance Use disorders (SUD) Committee for DSM-IV and cochair of the international group of experts reviewing the SUD definitions for DSM-V.

Toward an electrical power utility for space exploration

NASA Technical Reports Server (NTRS)

Bercaw, Robert W.

1989-01-01

Future electrical power requirements for space exploration are discussed. Megawatts of power with enough reliability for multi-year missions and with enough flexibility to adapt to needs unanticipated at design time are some of the criteria which space power systems must be able to meet. The reasons for considering the power management and distribution in the various systems, from a total mission perspective rather than simply extrapolating current spacecraft design practice, are discussed. A utility approach to electric power integrating requirements from a broad selection of current development programs, with studies in which both space and terrestrial technologies are conceptually applied to exploration mission scenarios, is described.

Clinicians’ Use of Personality Disorder Models within a Particular Treatment Setting: A Longitudinal Comparison of Temporal Consistency and Clinical Utility

PubMed Central

Samuel, Douglas B.; Widiger, Thomas A.

2012-01-01

An active line of current investigation is how the five-factor model (FFM) of personality disorder might be applied by clinicians and particularly, how clinically useful this model is in comparison to the existing nomenclature. The current study is the first to investigate the temporal consistency of clinicians’ application of the FFM and the DSM-IV-TR to their own patients. Results indicated that FFM ratings were relatively stable over six-months of treatment, supporting their use by clinicians, but also indexed potentially important clinical changes. Additionally, ratings of utility provided by the clinicians suggested that the FFM was more useful for clinical decision making than was the DSM-IV-TR model. We understand the clinical utility findings within the context of previous research indicating that the FFM is most useful among patients who are not prototypic for a personality disorder.

We are building a multidisciplinary research program linking researchers in agriculture, business, earth science, engineering, humanities and social science. Our goal is to match renewable energy supply and reformed energy demands. The program will be focused on (i) understanding and modifying energy demand, (ii) design and implementation of diverse renewable energy networks. Geomatics technology will be used to map existing energy and waste flows on a neighbourhood, municipal, and regional level. Optimal sites and combinations of sites for solar and wind electrical generation (ridges, rooftops, valley walls) will be identified. Geomatics based site and grid analyses will identify best locations for energy production based on efficient production and connectivity to regional grids and transportation. Design of networks for utilization of waste streams of heat, water, animal and human waste for energy production will be investigated. Agriculture, cities and industry produce many waste streams that are not well utilized. Therefore, establishing a renewable energy resource mapping and planning program for electrical generation, waste heat and energy recovery, biomass collection, and biochar, biodiesel and syngas production is critical to regional energy optimization. Electrical storage and demand management are two priorities that will be investigated. Regional scale cooperatives may use electric vehicle batteries and innovations such as pump storage and concentrated solar molten salt heat storage for steam turbine electrical generation. Energy demand management is poorly explored in Canada and elsewhere - our homes and businesses operate on an unrestricted demand. Simple monitoring and energy demand-ranking software can easily reduce peaks demands and move lower ranked uses to non-peak periods, thereby reducing the grid size needed to meet peak demands. Peak demand strains the current energy grid capacity and often requires demand balancing projects and infrastructure that is highly inefficient due to overall low utilization.

Electric utility pole yard training facility: Designing an effective learning environment

NASA Astrophysics Data System (ADS)

Topping, Robert P.

The primary responsibility of electric utilities is to supply consistent, dependable, and affordable energy to private customers, businesses, and industries. As with many businesses, electric utilities are experiencing the effects of an aging workforce and expending considerable resources to train their current and replacement workers. Community colleges can partner with electric utilities to provide effective learning environments for these workers, and gain access to new sources of revenue and community support for the colleges. The purpose of this study was to describe the functions, features, and major design issues of an effective learning environment for training electric utility industry workers, the electric utility line-worker pole yard. Case studies of three "state of the art" line-worker pole yard training environments provide the basis for the study's findings and implications. The study was guided by the following research questions: (1) What is the function of a line-worker pole yard in supporting effective training? (2) What are the features of present day ("state of the art") line-worker pole yard learning environments? and (3) What are the major issues that need to be addressed in designing a line-worker pole yard learning environment for the future? The study participants included industry representatives, training coordinators, instructors, and students from the three selected "state of the art" line-worker pole yard sites. The overall findings from the study resulted in composites of the desired features of learning outcomes, learning process, and learning environment for a line-worker pole yard training program and major issues that are affecting the future design of these training programs. Composite findings of a pole-yard training environment included unique features associated with: (a) outdoor, (b) indoor, (c) underground, (d) classroom, (e) gathering places, and (f) work-based learning components. Composite findings with regard to major issues that need to be considered in future designs of pole-yard training environments included: (a) available unrestricted land for expansion, (b) resource commitment level, (c) workforce demographics, (d) aging industrial infrastructure, (e) electronic information and communication capability, (f) quality and quantity of available instructors, and (g) environmental and economic impact.

The technology and economics of the large, horizontal-axis wind turbines currently in the Federal Wind Energy Program are presented. Wind turbine technology advancements made in the last several years are discussed. It is shown that, based on current projections of the costs of these machines when produced in quantity, they should be attractive for utility application. The cost of electricity (COE) produced at the busbar is shown to be a strong function of the mean wind speed at the installation site. The breakeven COE as a fuel saver is discussed and the COE range that would be generally attractive to utilities is indicated.

The effect of state-level funding on energy efficiency outcomes

NASA Astrophysics Data System (ADS)

Downs, Anna

Increasingly, states are formalizing energy efficiency policies. In 2010, states required utilities to budget $5.5 billion through ratepayer-funded energy efficiency programs, investing in both electricity and natural gas programs. However the size and spread of energy efficiency programs was strikingly different from state to state. This paper examines how far each dollar of state-level energy efficiency funding goes in producing efficiency gains. Many states have also pursued innovative policy actions to conserve electricity. Measures of policy effort are also included in this study, along with average electricity prices. The only variable that is consistently correlated with energy usage intensity across all models is electricity price. As politicians at local, state, and Federal levels continue to push for improved energy efficiency, the models in this paper provide a convincing impetus for focusing on strategies that raise energy prices.

Design study of wind turbines, 50 kW to 3000 kW for electric utility applications: Executive summary

NASA Technical Reports Server (NTRS)

1977-01-01

Preliminary designs of low power (50 to 500 kW) and high power (500 to 3000 kW) wind generator systems (WGS) for electric utility applications were developed. These designs provide the bases for detail design, fabrication, and experimental demonstration testing of these units at selected utility sites. Several feasible WGS configurations were evaluated, and the concept offering the lowest energy cost potential and minimum technical risk for utility applications was selected. The selected concept was optimized utilizing a parametric computer program prepared for this purpose. The utility requirements evaluation task examined the economic, operational and institutional factors affecting the WGS in a utility environment, and provided additional guidance for the preliminary design effort. Results of the conceptual design task indicated that a rotor operating at constant speed, driving an AC generator through a gear transmission is the most cost effective WGS configuration.

On the convergence between PSY-5 domains and PID-5 domains and facets: implications for assessment of DSM-5 personality traits.

The DSM-5 Personality and Personality Disorders workgroup and their consultants have developed the 220-item, self-report Personality Inventory for the DSM-5 (PID-5) for direct assessment of the proposed personality trait system for DSM-5; however, most practicing clinical psychologists will likely continue to rely on separate omnibus measures to index symptoms and traits associated with psychopathology. The Minnesota Multiphasic Personality Inventory-2 Restructured Form (MMPI-2-RF) is one such measure and assesses the Personality Psychopathology Five (PSY-5) domains, which are conceptual cognates of the DSM-5 trait domains. The current study examined the associations between the MMPI-2-RF PSY-5 scales and the DSM-5 trait domains and facets indexed by the PID-5. A clear pattern of convergence was found indicating that each of the PSY-5 scales was most highly correlated with its conceptually expected PID-5 counterpart (rs = .44-.67; Mdn r = .53) and facet correlations generally showed the same pattern. Similarly, when each of the PSY-5 scales was regressed onto the PID-5 domains, the conceptually expected pattern of associations emerged even more clearly. Finally, a joint exploratory factor analysis with the PSY-5 and PID-5 trait facet scales indicated a five-factor solution that clearly resembled both of the PSY-5/DSM-5 trait domains. These results show clear evidence that the MMPI-2-RF has utility in the assessment of dimensional personality traits proposed for the upcoming DSM-5.

Changes in the DSM-5 eating disorders criteria sought to increase the clarity of the diagnostic categories and to decrease the preponderance of nonspecified eating disorders. The first objective of this study was to analyze how these revisions affect threshold and EDNOS/OSFED eating disorder diagnoses in terms of prevalence, sex ratios, and diagnostic distribution in a student sample. Second, we aimed to compare the impairment levels of participants with a threshold, an EDNOS/OSFED and no diagnosis using both DSM-IV and DSM-5. A sample of 1654 7th and 8th grade students completed self-report questionnaires to determine diagnoses and impairment levels in the context of an eating disorder prevention program in nine German secondary schools. Height and weight were measured. The prevalence of threshold disorders increased from .48% (DSM-IV) to 1.15% (DSM-5). EDNOS disorders increased from 2.90 to 6.23% when using OSFED-categories. A higher proportion of girls was found throughout all the diagnostic categories, and the sex ratios remained stable. The effect sizes of DSM-5 group differences regarding impairment levels were equal to or larger than those of the DSM-IV comparisons, ranging from small to medium. We provide an in-depth overview of changes resulting from the revisions of DSM eating disorder criteria in a German adolescent sample. Despite the overall increase in prevalence estimates, the results suggest that the DSM-5 criteria differentiate participants with threshold disorders and OSFED from those no diagnosis as well as or even more distinctly than the DSM-IV criteria. © 2017 Wiley Periodicals, Inc.

Accuracy of DSM based on digital aerial image matching. (Polish Title: Dokładność NMPT tworzonego metodą automatycznego dopasowania cyfrowych zdjęć lotniczych)

Digital Surface Models (DSM) are used in GIS data bases as single product more often. They are also necessary to create other products such as3D city models, true-ortho and object-oriented classification. This article presents results of DSM generation for classification of vegetation in urban areas. Source data allowed producing DSM with using of image matching method and ALS data. The creation of DSM from digital images, obtained by Ultra Cam-D digital Vexcel camera, was carried out in Match-T by INPHO. This program optimizes the configuration of images matching process, which ensures high accuracy and minimize gap areas. The analysis of the accuracy of this process was made by comparison of DSM generated in Match-T with DSM generated from ALS data. Because of further purpose of generated DSM it was decided to create model in GRID structure with cell size of 1 m. With this parameter differential model from both DSMs was also built that allowed determining the relative accuracy of the compared models. The analysis indicates that the generation of DSM with multi-image matching method is competitive for the same surface model creation from ALS data. Thus, when digital images with high overlap are available, the additional registration of ALS data seems to be unnecessary.

2018-02-01

A new severity specifier for bulimia nervosa (BN), based on the frequency of inappropriate weight compensatory behaviours (e.g., laxative misuse, self-induced vomiting, fasting, diuretic misuse, and excessive exercise), has been added to the most recent (fifth) edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) as a means of addressing variability and heterogeneity in the severity of the disorder. While existing research provides support for the DSM-5 severity specifier for BN in adult patients, evidence for its validity and clinical utility in youth is currently lacking. To address this gap, data from 272 treatment-seeking adolescents with DSM-5 BN (94.2% female, M age  = 15.3 years, SD 1.7) were analysed to examine whether these patients, sub-grouped based on the DSM-5 severity definitions, would show meaningful differences in a broad range of clinical variables and demographic and physical characteristics. Analyses revealed that participants categorized with mild, moderate, severe, and extreme severity of BN significantly differed from each other in 15 variables regarding eating disorder pathological features and putative maintenance factors (i.e., core low self-esteem, perfectionism, social appearance anxiety, body surveillance, and mood intolerance), health-related quality of life and comorbid psychiatric (i.e., affective and anxiety) disorders (large effect sizes). Between-group differences in demographics, body mass index, or age-of-BN onset were not observed. Collectively, our findings provide support for the utility of the frequency of inappropriate weight compensatory behaviours as a severity indicator for BN and suggest that age-at-onset of BN is probably more disorder- than severity-dependent. Implications for future research are outlined.

Dimensional assessment of anxiety disorders in parents and children for DSM-5.

2014-09-01

The current shift in the DSM towards the inclusion of a dimensional component allows clinicians and researchers to demonstrate not only the presence or absence of psychopathology in an individual, but also the degree to which the disorder and its symptoms are manifested. This study evaluated the psychometric properties and utility of a set of brief dimensional scales that assess DSM-based core features of anxiety disorders, for children and their parents. The dimensional scales and the Screen for Child Anxiety Related Emotional Disorders (SCARED-71), a questionnaire to assess symptoms of all anxiety disorders, were administered to a community sample of children (n = 382), aged 8-13 years, and their mothers (n = 285) and fathers (n = 255). The dimensional scales assess six anxiety disorders: specific phobia, agoraphobia, panic disorder, social anxiety disorder, generalized anxiety disorder, and separation anxiety disorder. Children rated their own anxiety and parents their child's anxiety. The dimensional scales demonstrated high internal consistency (α > 0.78, except for father reported child panic disorder, for reason of lack of variation), and moderate to high levels of convergent validity (rs  = 0.29-0.73). Children who exceeded the SCARED cutoffs scored higher on the dimensional scales than those who did not, providing preliminary support for the clinical sensitivity of the scales. Given their strong psychometric properties and utility for both child and parent report, addition of the dimensional scales to the DSM-5 might be an effective way to incorporate dimensional measurement into the categorical DSM-5 assessment of anxiety disorders in children.

1984-01-01

Assessing the performance of a MOD-OA horizontal axis wind turbine connected to an isolated diesel utility, a comprehensive data measurement program was conducted on the Block Island Power Company installation on Block Island, Rhode Island. The detailed results of that program focusing on three principal areas of (1) fuel displacement (savings), (2) dynamic interaction between the diesel utility and the wind turbine, (3) effects of three models of wind turbine reactive power control are presented. The approximate two month duration of the data acquisition program conducted in the winter months (February into April 1982) revealed performance during periods of highest wind energy penetration and hence severity of operation. Even under such conditions fuel savings were significant resulting in a fuel reduction of 6.7% while the MOD-OA was generating 10.7% of the total electrical energy. Also, electrical disturbance and interactive effects were of an acceptable level.

We examined the validity and utility of the DSM-5 severity ratings for anorexia nervosa (AN) in a clinical (treatment-seeking) sample (N = 273; 95.6% women). Participants classified with mild, moderate, severe, and extreme severity of AN based on their measured body mass index, differed significantly from each other in eating disorder features, putative maintenance factors, and illness-specific functional impairment (medium effect sizes). However, they were statistically indistinguishable in psychiatric-disorder comorbidity and distress, demographics, and age-of-AN onset. The implications of our findings, providing limited support for the DSM-5 severity ratings for AN, and directions for future research are outlined. Copyright © 2018 Elsevier B.V.

Discussion paper on wholesale ratemaking considerations for sulfur dioxide emissions allowance trading

DOE Office of Scientific and Technical Information (OSTI.GOV)

Wessler, E.

1993-07-01

The acid rain provisions of the Clean Air Act Amendments of 1990 (CAAA) created an allowance trading program for SO{sub 2} emissions from electric utility power plants. Theoretically, the trading program will provide utilities the flexibility to control their SO{sub 2} emissions at minimum aggregate societal costs. The trading program is a significant change from command-and-control environmental policies. A continuing concern is whether the market-oriented trading program is compatible with the pervasive rate regulation of the electric utility industry. Economists accept traditional rate regulation policies tend to provide incentives for utilities to minimize risks, rather than costs. To the extentmore » that this is true, the allowance trading experiment is not likely to be successful. A number of commenters have described proposals for alternative regulatory policies to provide utilities with appropriate incentives for cost-minimization. These proposals focus on utility incentives at a {open_quotes}macro{close_quotes} level This paper has a {open_quotes}micro{close_quotes} level focus. It examines options for ratemaking that may also influence utility incentives for cost-minimization to provide a structured discussion of the different types of transactions that involve allowances. Emphasis is on the implications of allowance trading on ratemaking for wholesale power sales. Some of the same considerations that apply to wholesale ratemaking may also apply to retail ratemaking. Four generic types of allowance transactions are examined: Type 1: Unbundled Allowance Sales, Type 2: Wholesale Power Sales, Type 3: Pooling Arrangements, and Type 4: Holding Company Transactions. Each of these four generic allowance transactions is assessed along two 3 dimensions: jurisdictional issues and wholesale ratemaking considerations.« less

Rhodococcus opacus DSM 1069 utilized pine organosolv pretreatment effluent as a sole carbon and energy source for 120 h at 1.5 w/v% solids concentration and accumulated a maximum of 26.99 ± 2.88% of its cellular dry weight in oils composed of oleic, palmitic, and stearic fatty acids. Here, these results establish the potential for lignocellulosic pretreatment effluent as a feedstock for microbial biodiesel production via oleaginous R. opacus and an interesting route for biorefinery waste stream optimization.

Church-based health programs for mental disorders among African Americans: a review.

PubMed

Hankerson, Sidney H; Weissman, Myrna M

2012-03-01

African Americans underutilize traditional mental health services, compared with white Americans. The authors conducted a systematic review of studies involving church-based health promotion programs for mental disorders among African Americans to assess the feasibility of utilizing such programs to address racial disparities in mental health care. A literature review of MEDLINE, PsycINFO, CINAHL, and ATLA Religion databases was conducted to identify articles published between January 1, 1980, and December 31, 2009. Inclusion criteria were as follows: studies were conducted in a church; the primary objective involved assessment, perceptions and attitudes, education, prevention, group support, or treatment for DSM-IV mental disorders or their correlates; number of participants was reported; qualitative or quantitative data were reported; and African Americans were the target population. Of 1,451 studies identified, only eight met inclusion criteria. Five studies focused on substance-related disorders, six were designed to assess the effects of a specific intervention, and six targeted adults. One study focused on depression and was limited by a small sample size of seven participants. Although church-based health promotion programs have been successful in addressing racial disparities for several chronic medical conditions, the literature on such programs for mental disorders is extremely limited. More intensive research is needed to establish the feasibility and acceptability of utilizing church-based health promotion programs as a possible resource for screening and treatment to improve disparities in mental health care for African Americans.

Next-Generation Performance-Based Regulation: Emphasizing Utility Performance to Unleash Power Sector Innovation

DOE Office of Scientific and Technical Information (OSTI.GOV)

Logan, Jeffrey S; Zinaman, Owen R; Littell, David

Performance-based regulation (PBR) enables regulators to reform hundred-year-old regulatory structures to unleash innovations within 21st century power systems. An old regulatory paradigm built to ensure safe and reliable electricity at reasonable prices from capital-intensive electricity monopolies is now adjusting to a new century of disruptive technological advances that change the way utilities make money and what value customers expect from their own electricity company. Advanced technologies are driving change in power sectors around the globe. Innovative technologies are transforming the way electricity is generated, delivered, and consumed. These emerging technology drivers include renewable generation, distributed energy resources such as distributedmore » generation and energy storage, demand-side management measures such as demand-response, electric vehicles, and smart grid technologies and energy efficiency (EE). PBR enables regulators to recognize the value that electric utilities bring to customers by enabling these advanced technologies and integrating smart solutions into the utility grid and utility operations. These changes in the electric energy system and customer capacities means that there is an increasing interest in motivating regulated entities in other areas beyond traditional cost-of-service performance regulation. This report addresses best practices gleaned from more than two decades of PBR in practice, and analyzes how those best practices and lessons can be used to design innovative PBR programs. Readers looking for an introduction to PBR may want to focus on Chapters 1-5. Chapters 6 and 7 contain more detail for those interested in the intricate workings of PBR or particularly innovative PBR.« less

Machado, Paulo P P; Grilo, Carlos M; Crosby, Ross D

2017-05-01

This study tested the new DSM-5 severity criterion for anorexia nervosa (AN) based on proposed body mass index (BMI) cut-points. Participants were a clinical sample of 201 treatment-seeking patients diagnosed with DSM-5 AN in Portugal. Participants were categorised based on DSM-5 severity levels and were compared on demographic and clinical variables assessed with the Eating Disorder Examination-Questionnaire. Based on DSM-5 severity definitions for AN, 73 (36.3%) participants were categorised as mild (≥17.0 BMI), 40 (19.9%) as moderate (16-16.99 BMI), 30 (14.9%) as severe (15-15.99 BMI) and 58 (28.9%) as extreme (<15 BMI). The severity groups did not differ significantly in age or gender. Analyses comparing the severity groups on measures of eating-disorder psychopathology revealed no significant differences on the Eating Disorder Examination-Questionnaire global or subscale scores. The groups also did not differ significantly on the frequency of binge eating or purging episodes within the past 28 days. Our findings, in this clinical sample of patients with AN in Portugal, provide no evidence for the new DSM-5 severity ratings based on BMI level.

Substance dependence and non-dependence in the Diagnostic and Statistical Manual of Mental Disorders (DSM) and the International Classification of Diseases (ICD): can an identical conceptualization be achieved?

PubMed

Saunders, John B

2006-09-01

This review summarizes the history of the development of diagnostic constructs that apply to repetitive substance use, and compares and contrasts the nature, psychometric performance and utility of the major diagnoses in the Diagnostic and Statistical Manual of Mental Disorders (DSM) and International Classification of Diseases (ICD) diagnostic systems. The available literature was reviewed with a particular focus on diagnostic concepts that are relevant for clinical and epidemiological practice, and so that research questions could be generated that might inform the development of the next generation of DSM and ICD diagnoses. The substance dependence syndrome is a psychometrically robust and clinically useful construct, which applies to a range of psychoactive substances. The differences between the DSM fourth edition (DSM-IV) and the ICD tenth edition (ICD-10) versions are minimal and could be resolved. DSM-IV substance abuse performs moderately well but, being defined essentially by social criteria, may be culture-dependent. ICD-10 harmful substance use performs poorly as a diagnostic entity. There are good prospects for resolving many of the differences between the DSM and ICD systems. A new non-dependence diagnosis is required. There would also be advantages in a subthreshold diagnosis of hazardous or risky substance use being incorporated into the two systems. Biomedical research can be drawn upon to define a psychophysiological 'driving force' which could underpin a broad spectrum of substance use disorders.

Many electric utilities operate energy efficiency incentive programs that encourage increased dissemination and use of energy-efficient (EE) products in their service territories. The programs can be segmented into three broad categories—downstream incentive programs target product end users, midstream programs target product distributors, and upstream programs target product manufacturers. Traditional downstream programs have had difficulty engaging Small Business/Small Portfolio (SBSP) audiences, and an opportunity exists to expand Commercial Midstream Incentive Programs (CMIPs) to reach this market segment instead.

Systems definition space-based power conversion systems. [for satellite power transmission to earth

NASA Technical Reports Server (NTRS)

1976-01-01

Potential space-located systems for the generation of electrical power for use on Earth are discussed and include: (1) systems producing electrical power from solar energy; (2) systems producing electrical power from nuclear reactors; and (3) systems for augmenting ground-based solar power plants by orbital sunlight reflectors. Systems (1) and (2) would utilize a microwave beam system to transmit their output to Earth. Configurations implementing these concepts were developed through an optimization process intended to yield the lowest cost for each. A complete program was developed for each concept, identifying required production rates, quantities of launches, required facilities, etc. Each program was costed in order to provide the electric power cost appropriate to each concept.

Objective This study evaluated whether the Broad Categories for the Diagnosis of Eating Disorders (BCD-ED) proposal (Walsh & Sysko, 2009) reduces the number of individuals who receive a DSM-IV eating disorder not otherwise specified (EDNOS) diagnosis. Method Individuals calling a tertiary care facility completed a brief telephone interview and were classified into a DSM-IV eating disorder category (anorexia nervosa, bulimia nervosa, EDNOS). Subsequently, the proposed DSM-5 criteria for eating disorders and the BCD-ED scheme were also applied. Results A total of 247 individuals with telephone interview data met criteria for an eating disorder, including 97 (39.3%) with an EDNOS. Of patients with an EDNOS diagnosis, 97.6% were re-classified using the BCD-ED scheme. Discussion The BCD-ED scheme has the potential to virtually eliminate the use of DSM-IV EDNOS; however, additional data are needed to document its validity and clinical utility. PMID:21997426

Background and rationale for the Society of Behavioral Medicine's position statement: expand United States health plan coverage for diabetes self-management education and support.

2015-09-01

The Society of Behavioral Medicine (SBM) recognizes that diabetes self-management (DSM) education and support are fundamental to teaching people how to manage their diabetes and decrease disease-related complications. Implementation of the Patient Protection and Affordable Care Act provides an opportunity to expand DSM education and support to many people who are currently excluded from such services due to lack of insurance coverage, current policy barriers, or simple failure of healthcare systems to provide them. Extending the range and provision of such services could translate into reduced diabetic complications, a reduction in unnecessary healthcare utilization, and significant health-related cost savings on a national level. SBM recommends that public and private insurers be required to reimburse for 12 h of DSM education and support annually for anyone with diabetes. Further, SBM recognizes that a range of modes and providers of DSM education and support have been shown effective, and that patient preferences and resources may influence choice. To address this, SBM urges health organizations to increase and diversify approaches toward DSM education and support they offer.

The extended multigenerational family is a core value of Hispanic culture. Family cohesion/pride can have protective effects on drinking- and drug-use-related behavior among Hispanics. To examine the association between family cohesion/pride, drinking, binge drinking, and DSM-5 alcohol use disorder (AUD) in Puerto Rico. Data are from a household random sample of 1510 individuals 18-64 years of age in San Juan, Puerto Rico. Bivariate analyses showed that family cohesion/pride was not associated with the average number of drinks consumed per week but was associated with binge drinking among men. Family cohesion/pride was also associated with DSM-5 AUD. Results of the multivariate analyses were consistent with these bivariate results for DSM-5 AUD. Respondents with low (OR = 2.2, 95CL = 1.21-3.98; p < .01) and medium (OR = 1.88; 95CL = 1.12-3.14; p < .01) family cohesion/pride were more likely than those with high family cohesion/pride to have a positive diagnosis of DSM-5 AUD. More liberal drinking norms and positive attitudes toward drinking were also strong predictors of the average number of drinks consumed per week. More liberal drinking norms also predicted binge drinking, and DSM-5 AUD. Higher family cohesion/pride may have a protective effect against DSM-5 AUD. This may have practical implications for clinical and prevention programs. As long as high cohesion is not enabling drinking, these programs can enhance and support family cohesion/pride to help clients in treatment and recovery and prevent drinking problems.

1993-10-01

The Electric Power Research Institute (EPRI) commissioned a radioactive waste related project (RP2414-34) in 1989 to produce a guide for developing and managing nuclear plant protective clothing programs. Every nuclear facility must coordinate some type of protective clothing program for its radiation workers to ensure proper and safe protection for the wearer and to maintain control over the spread of contamination. Yet, every nuclear facility has developed its own unique program for managing such clothing. Accordingly, a need existed for a reference guide to assist with standardizing protective clothing programs and in controlling the potentially escalating economics of such programs.more » The initial Guide to Managing Nuclear Utility Protective Clothing Programs, NP-7309, was published in May 1991. Since that time, a number of utilities have reviewed and/or used the report to enhance their protective clothing programs. Some of these utilities requested that a computer program be developed to assist utilities in evaluating the economics of protective clothing programs consistent with the guidance in NP-7309. The PCEVAL computer code responds to that industry need. This report, the PCEVAL User`s Manual, provides detailed instruction on use of the software.« less

Development of large, horizontal-axis wind turbines

Baldwin, D. H.; Kennard, J.

1985-01-01

A program to develop large, horizontal-axis wind turbines is discussed. The program is directed toward developing the technology for safe, reliable, environmentally acceptable large wind turbines that can generate a significant amount of electricity at costs competitive with those of conventional electricity-generating systems. In addition, these large wind turbines must be fully compatible with electric utility operations and interface requirements. Several ongoing projects in large-wind-turbine development are directed toward meeting the technology requirements for utility applications. The machines based on first-generation technology (Mod-OA and Mod-1) successfully completed their planned periods of experimental operation in June, 1982. The second-generation machines (Mod-2) are in operation at selected utility sites. A third-generation machine (Mod-5) is under contract. Erection and initial operation of the Mod-5 in Hawaii should take place in 1986. Each successive generation of technology increased reliability and energy capture while reducing the cost of electricity. These advances are being made by gaining a better understanding of the system-design drivers, improving the analytical design tools, verifying design methods with operating field data, and incorporating new technology and innovative designs. Information is given on the results from the first- and second-generation machines (Mod-OA, - 1, and -2), the status of the Department of Interior, and the status of the third-generation wind turbine (Mod-5).

Post electrical or lightning injury syndrome: a proposal for an American Psychiatric Association's Diagnostic and Statistical Manual formulation with implications for treatment.

Andrews, Christopher J; Reisner, Andrew D; Cooper, Mary Ann

2017-09-01

In the past, victims of electrical and lightning injuries have been assessed in a manner lacking a systematic formulation, and against ad hoc criteria, particularly in the area of neuropsychological disability. In this manner patients have, for example, only been partially treated, been poorly or incorrectly diagnosed, and have been denied the full benefit of compensation for their injuries. This paper contains a proposal for diagnostic criteria particularly for the neuropsychological aspects of the post injury syndrome. It pays attention to widely published consistent descriptions of the syndrome, and a new cluster analysis of post electrical injury patients. It formulates a proposal which could be incorporated into future editions of the American Psychiatric Association's Diagnostic and Statistical Manual (DSM). The major neuropsychological consequences include neurocognitive dysfunction, and memory subgroup dysfunction, with ongoing consequences, and sometimes including progressive or delayed psychiatric, cognitive, and/or neurological symptoms. The proposed diagnostic criteria insist on a demonstrated context for the injury, both specifying the shock circumstance, and also physical consequences. It allows for a certain delay in onset of symptoms. It recognizes exclusory conditions. The outcome is a proposal for a DSM classification for the post electrical or lightning injury syndrome. This proposal is considered important for grounding patient treatment, and for further treatment trials. Options for treatment in electrical or lightning injury are summarised, and future trials are foreshadowed.

ZiYuan-3 (ZY-3), launched in January 09, 2012, is China's first civilian high-resolution stereo mapping satellite. ZY-3 is equipped with three-line scanners (nadir, backward and forward) for stereo mapping, the resolutions of the panchromatic (PAN) stereo mapping images are 2.1-m at nadir looking and 3.6-m at tilt angles of ±22° forward and backward looking, respectively. The stereo base-height ratio is 0.85-0.95. Compared with stereo mapping from two views images, three-line arrays images of ZY-3 can be used for DSM generation taking advantage of one more view than conventional photogrammetric methods. It would enrich the information for image matching and enhance the accuracy of DSM generated. The primary result of positioning accuracy of ZY-3 images has been reported, while before the massive mapping applications of utilizing ZY-3 images for DSM generation, the performance evaluation of DSM extraction from three-line arrays imagery of ZY-3 has significant meaning for the routine mapping applications. The goal of this research is to clarify the mapping performance of ZY-3 three-line arrays scanners on china's first civilian high-resolution stereo mapping satellite of ZY-3 through the accuracy evaluation of DSM generation. The comparison of DSM product in different topographic areas generated with three views images with different two views combination images of ZY-3 would be presented. Besides the comparison within different topographic study area, the accuracy deviation of the DSM products with different grid size including 25-m, 10-m and 5-m is delineated in order to clarify the impact of grid size on accuracy evaluation.

Should there be both categorical and dimensional criteria for the substance use disorders in DSM-V?

PubMed

Helzer, John E; van den Brink, Wim; Guth, Sarah E

2006-09-01

As discussed in the following literature review, the relative advantages of categorical and dimensional criteria for classifying the substance use disorders (SUDs) have been debated for many years. The scheduled revision of the Diagnostic and Statistical Manual (DSM) offers an opportunity to re-examine this question. Both categorical and dimensional approaches to diagnosis offer advantages, both may in fact be necessary for a comprehensive taxonomy. One means of resolving debate about the direction to take in revising DSM-V and simultaneously of achieving maximum taxonomic utility is to include both categorical and dimensional criteria in DSM-V. This could be accomplished by first defining a set of categorical criteria, as in the previous editions of the DSM. Corresponding dimensional criteria could then be created using a more empirical methodology. In this paper we review some of the relevant literature, offer a specific proposal for a dimensional component for the DSM-V substance use disorders that also preserves the categorical definitions and suggest areas for additional research relevant the this agenda. There is evidence that alcohol and other forms of substance abuse and dependence are heterogeneous categories and that the SUDs can be conceptualized viably as arrayed along a continuum. Amplifying clinically derived categorical definitions with more empirically derived dimensional components to better capture this variability is a particularly important consideration for a substance use research agenda for DSM-V. It is crucial that a dimensional approach be offered in some form in DSM-V; but it is also vital that any dimensional approach be linked to the categorical definition. The proposal offered herein provides a model for amplifying categorical definitions with a dimensional component in a way that is evolutionary and not disruptive to the existing taxonomy.

Insights into the degradation capacities of Amycolatopsis tucumanensis DSM 45259 guided by microarray data.

The analysis of catabolic capacities of microorganisms is currently often achieved by cultivation approaches and by the analysis of genomic or metagenomic datasets. Recently, a microarray system designed from curated key aromatic catabolic gene families and key alkane degradation genes was designed. The collection of genes in the microarray can be exploited to indicate whether a given microbe or microbial community is likely to be functionally connected with certain degradative phenotypes, without previous knowledge of genome data. Herein, this microarray was applied to capture new insights into the catabolic capacities of copper-resistant actinomycete Amycolatopsis tucumanensis DSM 45259. The array data support the presumptive ability of the DSM 45259 strain to utilize single alkanes (n-decane and n-tetradecane) and aromatics such as benzoate, phthalate and phenol as sole carbon sources, which was experimentally validated by cultivation and mass spectrometry. Interestingly, while in strain DSM 45259 alkB gene encoding an alkane hydroxylase is most likely highly similar to that found in other actinomycetes, the genes encoding benzoate 1,2-dioxygenase, phthalate 4,5-dioxygenase and phenol hydroxylase were homologous to proteobacterial genes. This suggests that strain DSM 45259 contains catabolic genes distantly related to those found in other actinomycetes. Together, this study not only provided new insight into the catabolic abilities of strain DSM 45259, but also suggests that this strain contains genes uncommon within actinomycetes.

Panic disorder and agoraphobia: an overview and commentary on DSM-5 changes.

PubMed

Asmundson, Gordon J G; Taylor, Steven; Smits, Jasper A J

2014-06-01

The recently published DSM-5 contains a number of changes pertinent to panic disorder and agoraphobia. These changes include separation of panic disorder and agoraphobia into separate diagnoses, the addition of criteria and guidelines for distinguishing agoraphobia from specific phobia, the addition of a 6-month duration requirement for agoraphobia, the addition of panic attacks as a specifier to any DSM-5 diagnosis, changes to descriptors of panic attack types, as well as various changes to the descriptive text. It is crucial that clinicians and researchers working with individuals presenting with panic attacks and panic-like symptoms understand these changes. The purpose of the current paper is to provide a summary of the main changes, to critique the changes in the context of available empirical evidence, and to highlight clinical implications and potential impact on mental health service utilization. Several of the changes have the potential to improve access to evidence-based treatment; yet, although certain changes appear justified in that they were based on converging evidence from different empirical sources, other changes appear questionable, at least based on the information presented in the DSM-5 text and related publications. Ongoing research of DSM-5 panic disorder and agoraphobia as well as application of the new diagnostic criteria in clinical contexts is needed to further inform the strengths and limitations of DSM-5 conceptualizations of panic disorder and agoraphobia. © 2014 Wiley Periodicals, Inc.

Borderline Personality Disorder and Personality Inventory for DSM-5 (PID-5): Dimensional personality assessment with DSM-5.

PubMed

Calvo, Natalia; Valero, Sergi; Sáez-Francàs, Naia; Gutiérrez, Fernando; Casas, Miguel; Ferrer, Marc

2016-10-01

Borderline personality disorder (BPD) diagnosis has been considered highly controversial. The Diagnostic and Statistical Manual of Mental Disorders 5th edition (DSM-5) proposes an alternative hybrid diagnostic model for personality disorders (PD), and the Personality Inventory for DSM-5 (PID-5) has adequate psychometric properties and has been widely used for the assessment of the dimensional component. Our aim was to analyze the utility of the personality traits presented in Section III of the DSM-5 for BPD diagnosis in an outpatient clinical sample, using the Spanish version of the PID-5. Two clinical samples were studied: BPD sample (n=84) and non-BPD sample (n=45). Between-sample differences in PID-5 scores were analyzed. The BPD sample obtained significantly higher scores in most PID-5 trait facets and domains. Specifically and after regression logistic analyses, in BPD patients, the domains of Negative Affectivity and Disinhibition, and the trait facets of emotional lability, [lack of] restricted affectivity, and impulsivity were more significantly associated with BPD. Although our findings are only partially consistent with the algorithm proposed by DSM-5, we consider that the combination of the PID-5 trait domains and facets could be useful for BPD dimensional diagnosis, and could further our understanding of BPD diagnosis complexity.

We report on a global survey of diagnosing mental health professionals, primarily psychiatrists, conducted as a part of the development of the ICD-11 mental and behavioural disorders classification. The survey assessed these professionals' use of various components of the ICD-10 and the DSM, their attitudes concerning the utility of these systems, and usage of "residual" (i.e., "other" or "unspecified") categories. In previous surveys, most mental health professionals reported they often use a formal classification system in everyday clinical work, but very little is known about precisely how they are using those systems. For example, it has been suggested that most clinicians employ only the diagnostic labels or codes from the ICD-10 in order to meet administrative requirements. The present survey was conducted with clinicians who were members of the Global Clinical Practice Network (GCPN), established by the World Health Organization as a tool for global participation in ICD-11 field studies. A total of 1,764 GCPN members from 92 countries completed the survey, with 1,335 answering the questions with reference to the ICD-10 and 429 to the DSM (DSM-IV, DSM-IV-TR or DSM-5). The most frequent reported use of the classification systems was for administrative or billing purposes, with 68.1% reporting often or routinely using them for that purpose. A bit more than half (57.4%) of respondents reported often or routinely going through diagnostic guidelines or criteria systematically to determine whether they apply to individual patients. Although ICD-10 users were more likely than DSM-5 users to utilize the classification for administrative purposes, other differences were either slight or not significant. Both classifications were rated to be most useful for assigning a diagnosis, communicating with other health care professionals and teaching, and least useful for treatment selection and determining prognosis. ICD-10 was rated more useful than DSM-5 for administrative purposes. A majority of clinicians reported using "residual" categories at least sometimes, with around 12% of ICD-10 users and 19% of DSM users employing them often or routinely, most commonly for clinical presentations that do not conform to a specific diagnostic category or when there is insufficient information to make a more specific diagnosis. These results provide the most comprehensive available information about the use of diagnostic classifications of mental disorders in ordinary clinical practice. © 2018 World Psychiatric Association.

Geomagnetic storms associated with sunspot and solar flare activity can disturb communications and disrupt electric power. A very severe geomagnetic storm could cause a major blackout with an economic impact of several billion dollars. The vulnerability of electric power systems in the northeast United States will likely increase during the 1990s because of the trend of transmitting large amounts of power over long distance to meet the electricity demands of this region. A comprehensive research program and a warning satellite to monitor the solar wind are needed to enhance the reliability of electric power systems under the influence of geomagnetic storms.

The best result was obtained when transformed components from minimum noise fraction (MNF) and DSM were combined in support vector machine (SVM) classifier. Wavelength regions at chlorophyll absorption green peak, red, red edge and Oxygen absorption at near infrared were identified for better species discrimination. In addition, input of DSM data reduces overestimation of low plant species and misclassification due to the shadow effect and inter-species morphological variation. This study establishes a framework for quick survey and update on wetland environment using UAV system. The findings indicate that the utility of UAV-borne hyperspectral and derived tree height information provides a solid foundation for further researches such as biological invasion monitoring and bio-parameters modelling in wetland.

Trade-off decisions in distribution utility management

NASA Astrophysics Data System (ADS)

Slavickas, Rimas Anthony

As a result of the "unbundling" of traditional monopolistic electricity generation and transmission enterprises into a free-market economy, power distribution utilities are faced with very difficult decisions pertaining to electricity supply options and quality of service to the customers. The management of distribution utilities has become increasingly complex, versatile, and dynamic to the extent that conventional, non-automated management tools are almost useless and obsolete. This thesis presents a novel and unified approach to managing electricity supply options and quality of service to customers. The technique formulates the problem in terms of variables, parameters, and constraints. An advanced Mixed Integer Programming (MIP) optimization formulation is developed together with novel, logical, decision-making algorithms. These tools enable the utility management to optimize various cost components and assess their time-trend impacts, taking into account the intangible issues such as customer perception, customer expectation, social pressures, and public response to service deterioration. The above concepts are further generalized and a Logical Proportion Analysis (LPA) methodology and associated software have been developed. Solutions using numbers are replaced with solutions using words (character strings) which more closely emulate the human decision-making process and advance the art of decision-making in the power utility environment. Using practical distribution utility operation data and customer surveys, the developments outlined in this thesis are successfully applied to several important utility management problems. These involve the evaluation of alternative electricity supply options, the impact of rate structures on utility business, and the decision of whether to continue to purchase from a main grid or generate locally (partially or totally) by building Non-Utility Generation (NUG).

This study examined the utility of the diagnosis of pedophilia in a sample of extra-familial child molesters assessed at a university teaching hospital between 1982 and 1992. Pedophilia was defined in one of four ways: (1) DSM diagnosis made by a psychiatrist; (2) deviant phallometric profile; (3) DSM diagnosis and a deviant phallometric profile; and, (4) high scores based on the Screening Scale for Pedophilic Interest (Seto & Lalumière, 2001). Demographic data, psychological tests, and offence history were obtained and group differences were analyzed along with the ability of certain variables to contribute uniquely to the classification of pedophilia. Results indicated that few significant differences existed on psychological measures between pedophilic and nonpedophilic extra-familial child molesters regardless of the classification system employed. Finally, results indicated that the procedures used to define pedophilia were not significantly related to one another. Results are discussed in terms of the utility of the diagnosis of pedophilia.

2015-04-01

Spatial pattern and the correlation of different soil and plant parameters were examined in a green bean field experiment carried out at the Mediterranean Agronomic Institute of Bari, Italy. The experiment aimed to evaluate the role of local processes of salt accumulation and transport which mainly influences the evapotranspiration (and thus the root uptake) processes under different water salinity levels. The experiment consisted of three transects of 30m length and 4.2 m width, irrigated with three different salinity levels (1dSm-1, 3dSm-1, 6dSm-1). Soil measurements (electrical conductivity and soil water content) were monitored along transects in 24 sites, 1 m apart by using TDR probes and Diviner 2000. Water storage measured by TDR and Diviner sensor were coupled for calculating directly the evapotranspiration fluxes along the whole soil profile under the different salinity levels imposed during the experiment. In the same sites, crop monitoring involved measurements of Leaf Area Index (LAI), Osmotic Potential (OP), Leaf Water Potential (LWP), and Root length Density (RlD). Soil and plant properties were analyzed by classical statistics, geostatistics methods and spectral analysis. Results indicated moderate to large spatial variability across the field for soil and plant parameters under all salinity treatments. Furthermore, cross-semivariograms exhibited a strong positive spatial interdependence between electrical conductivity of soil solution ECw with ET and RlD in transect treated with 3dSm-1 as well as with LAI in transect treated with 6dSm-1 at all 24 monitoring sites. Spectral analysis enabled to identify the observation window to sample the soil salinity information responsible for a given plant response (ET, OP, RlD). It is also allowed a clear identification of the spatial scale at which the soil water salinity level and distribution and the crop response in terms of actual evapotranspiration ET, RlD and OP, are actually correlated. Additionally, significant peaks in the power and coherency spectra around 6-8 m suggested organization into hierarchical levels of soil variability.

DSM-5 cannabis use disorder, substance use and DSM-5 specific substance-use disorders: Evaluating comorbidity in a population-based sample.

PubMed

Hayley, Amie C; Stough, Con; Downey, Luke A

2017-08-01

Cannabis use disorder (CUD) is frequently associated with concurrent substance use and/or comorbid substance use disorders (SUDs); however there is little specificity with regard to commonly abused individual drug types/classes. This study therefore aimed to provide insight into the degree of these co-occurring relationships across several specific newer and older generation illicit and prescription drugs. 36,309 adults aged 18+ from wave 3 of the National Epidemiologic Survey on Alcohol and Related Conditions (NESARC-III) were assessed. Weighted cross-tabulations and multivariable logistic regression analyses were used to evaluate comorbidity between current DSM-5 CUD, substance use and DSM-5 SUD. Current DSM-5 CUD is associated with greater lifetime use of all examined drug classes, and previous 12-month use of several newer-class illicit and prescription stimulant-based substances (all p< 0.05). Current DSM-5 CUD was similarly associated with increased incidence of a range of DSM-5 SUDs and was independently associated with concurrently reporting current DSM-5; sedative (Adjusted OR= 5.1, 95%CI 2.9-9.0), cocaine (AOR= 9.3, 95%CI 5.6-15.5), stimulant (AOR= 4.3, 95%CI 2.3-7.9), club drug (AOR= 16.1, 95%CI 6.3-40.8), opioid (AOR= 4.6, 95%CI 3.0-6.8) and alcohol-use disorder (AOR= 3.0, 95%CI 2.5-3.7); but not heroin or 'other' drug use disorder (both p>0.05). High comorbidity exists between DSM-5 CUD and many specific DSM-5 SUDs. Newer-class illicit and prescription stimulant-based drug use disorders are overrepresented among those with DSM-5 CUD. These findings underscore the need for tailored treatment programs for those presenting with DSM-5 CUD, and for greater treatment specification where poly-drug use is evident.

DSM-IV antisocial personality disorder and conduct disorder: evidence for taxonic structures among individuals with and without substance use disorders in the general population.

PubMed

Kerridge, Bradley T; Saha, Tulshi D; Hasin, Deborah S

2014-05-01

The categorical-dimensional status of DSM-IV (Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition) conduct disorder (CD) and antisocial personality disorder (ASPD) is a source of controversy. This study examined whether the underlying structure of DSM-IV CD and ASPD was dimensional or categorical (taxonic) among individuals with and without substance use disorders. Using a national large representative survey of U.S. adults (n = 43,093), taxometric analyses of DSM-IV CD and ASPD diagnostic criteria were conducted on the total sample and among those with and without substance use disorders. Results of three taxometric procedures were consistent in showing that the structures underlying DSM-IV CD and ASPD were clearly taxonic in the total sample and among individuals with and without substance use disorders. Comparison curve fit indices exceeded 0.57 for each model. Taxonic findings of the present study were in contrast to the dimensional results of prior taxometric research among incarcerated samples with substantial comorbidity of antisocial syndromes and substance use disorders. Results supported the categorical representation and diagnostic thresholds of ASPD and CD as defined in DSM-IV and DSM-5. That the structure of ASPD and CD may be taxonic suggests that further research on these disorders use group comparative designs in which samples with and without these disorders are compared in terms of sociodemographic and clinical correlates, comorbidity, and treatment utilization. The taxonic structure of ASPD and CD may contribute to future research on causal processes through which these antisocial syndromes develop.

Fuel cell power plants intended for electric utility and cogeneration applications are now in the design and construction stage. This paper describes economic and operational considerations being used in the development and design of plants utilizing air cooled phosphoric acid fuel cells. Fuel cell power plants have some unique characteristics relative to other types of power plants. As a result it was necessary to develop specific definitions of the fuel cell power plant characteristics in order to perform cost of electricity calculations. This paper describes these characteristics and describes the economic analyses used in the Westinghouse fuel cell power plant program.

1995-05-01

The integration of a heat pump heat source into a clothes dryer has been investigated by several U.S. and foreign appliance developers and manufacturers but no commercial or residential heat pump clothes dryers are currently available in North America. The objectives of this effort were to: (1) Evaluate a heat pump dryer prototype relative to residential dryer performance tests. (2) Quantify the product limitations. (3) Suggest design changes that would reduce the impact of the limitations or that have a positive impact on the benefits. (4) Position the product relative to utility DSM/IRP opportunities (e.g., reduced connected load, or energymore » conservation). (5) Develop preliminary cost data The program evaluated the performance of a prototype closed-cycle heat pump clothes dryer designed and built by the Nyle Corporation. The prototype design goals were: (1) Drying times equivalent to a conventional electric clothes dryer. (2) 60% reduction in energy consumption. (3) Effective lint removal (to prevent coil fouling). (4) Cool-down mode performance similar to conventional dryer. (5) 20 lb load capacity. (6) Low temperature dry for reduced clothes wrinkle. Test results indicated that the closed-cycle heat pump met some of the above mentioned goals but it fell short with respect to energy savings and dry time. Performance improvement recommendations were developed for the closed-cycle dryer approach. In addition, the closed-cycle design potential was compared to an open-cycle heat pump dryer configuration.« less

Fisher, Martin; Gonzalez, Marisol; Malizio, Joan

2015-11-01

This study aimed to determine the changes in diagnosis that occur in making the transition from Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV) to Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) criteria in an adolescent medicine eating disorder program. During the months of September 2011 through December 2012, a data sheet was completed at the end of each new outpatient eating disorder evaluation listing the patient's gender, age, ethnicity, weight, height, DSM-IV diagnosis, and proposed DSM-5 diagnosis. Distributions were calculated using the Mann-Whitney and Wilcoxon rank sum analyses to determine differences between diagnostic groups. There were 309 patients evaluated during the 16-month period. DSM-IV diagnoses were as follows: anorexia nervosa, 81 patients (26.2%); bulimia nervosa, 29 patients (9.4%); binge eating disorder, 1 patient (0.3%); and eating disorder not otherwise specified (EDNOS), 198 patients (64.6%). By contrast, DSM-5 diagnoses were as follows: anorexia nervosa, 100 patients; atypical anorexia nervosa, 93 patients; avoidant/restrictive food intake disorder, 60 patients; bulimia nervosa, 29 patients; purging disorder, 18 patients; unspecified feeding or eating disorder, 4 patients; subthreshold bulimia nervosa, 2 patients; subthreshold binge eating disorder, 2 patients; and binge eating disorder, 1 patient. Almost two thirds (64.6%) of the 309 patients had a diagnosis of EDNOS based on the DSM-IV criteria. By contrast, only four patients had a diagnosis of unspecified feeding or eating disorder based on the DSM-5 criteria. These data demonstrate that the goal of providing more specific diagnoses for patients with eating disorders has been accomplished very successfully by the new DSM-5 criteria.

Performance Modeling and Measurement of Parallelized Code for Distributed Shared Memory Multiprocessors

Waheed, Abdul; Yan, Jerry

1998-01-01

This paper presents a model to evaluate the performance and overhead of parallelizing sequential code using compiler directives for multiprocessing on distributed shared memory (DSM) systems. With increasing popularity of shared address space architectures, it is essential to understand their performance impact on programs that benefit from shared memory multiprocessing. We present a simple model to characterize the performance of programs that are parallelized using compiler directives for shared memory multiprocessing. We parallelized the sequential implementation of NAS benchmarks using native Fortran77 compiler directives for an Origin2000, which is a DSM system based on a cache-coherent Non Uniform Memory Access (ccNUMA) architecture. We report measurement based performance of these parallelized benchmarks from four perspectives: efficacy of parallelization process; scalability; parallelization overhead; and comparison with hand-parallelized and -optimized version of the same benchmarks. Our results indicate that sequential programs can conveniently be parallelized for DSM systems using compiler directives but realizing performance gains as predicted by the performance model depends primarily on minimizing architecture-specific data locality overhead.

Most states in the US are involved in electric industry restructuring, from considering the pros and cons in regulatory dockets to implementing legislative mandates for full restructuring and retail access for all consumers. Several states and utilities have initiated pilot programs in which multiple suppliers or service providers may compete for business and some utility customers can choose among competing suppliers. The State of New Hampshire has been experimenting with a pilot program, mandated by the State Legislature in 1995 and implemented by the New Hampshire Public Utilities Commission (NHPUC), before it implements full retail access. Green marketing, an attemptmore » to characterize the supplier or service provider as environmentally friendly without referring to the energy resource used to generate electricity, was used by several suppliers or service providers to attract customers. This appeal to environmental consumerism was moderately successful, but it raised a number of consumer protection and public policy issues. This issue brief examines the marketing methods used in New Hampshire and explores what green marketing might mean for the development of renewable energy generation. It also addresses the issues raised and their implications.« less

Holcomb, F.H.; Binder, M.J.; Taylor, W.R.

The supply of reliable, cost-effective electric power with minimal environmental impact is a constant concern of Department of Defense (DOD) installation energy personnel. Electricity purchased from the local utility is expensive and represents only about 30% of the original energy input at the generating station due to generation and distribution inefficiencies. Because of master metering and large air conditioning loads, the demand portion of the installation`s electric bill can be in excess of 50% of the total bill. While the electric utilities in the United States have a very good record of reliability, there is significant potential for improving themore » security of electrical power supplied by using on-site power generation. On-site, dispersed power generation can reduce power outages due to weather, terrorist activities, or lack of utility generating capacity. In addition, as increased emphasis is placed on global warming, acid rain, and air pollution in general, the development of clean, highly efficient power producing technologies is not only desirable, but mandatory. Since the majority of central heat plants on U.S. military installations are nearing the end of their useful life, there is an opportunity to replace outdated existing equipment with modem technologies.« less

Voluntary consumer decisions to buy electricity supplied from renewable energy sources represent a powerful market support mechanism for renewable energy development. In the early 1990s, a small number of U.S. utilities began offering 'green power' options to their customers. Since then, these products have become more prevalent, both from traditional utilities and from renewable energy marketers operating in states that have introduced competition into their retail electricity markets or offering renewable energy certificates (RECs) online. Today, more than half of all U.S. electricity customers have an option to purchase some type of green power product directly from a retail electricitymore » provider, while all consumers have the option to purchase RECs.

Grid integration and smart grid implementation of emerging technologies in electric power systems through approximate dynamic programming

NASA Astrophysics Data System (ADS)

Xiao, Jingjie

A key hurdle for implementing real-time pricing of electricity is a lack of consumers' responses. Solutions to overcome the hurdle include the energy management system that automatically optimizes household appliance usage such as plug-in hybrid electric vehicle charging (and discharging with vehicle-to-grid) via a two-way communication with the grid. Real-time pricing, combined with household automation devices, has a potential to accommodate an increasing penetration of plug-in hybrid electric vehicles. In addition, the intelligent energy controller on the consumer-side can help increase the utilization rate of the intermittent renewable resource, as the demand can be managed to match the output profile of renewables, thus making the intermittent resource such as wind and solar more economically competitive in the long run. One of the main goals of this dissertation is to present how real-time retail pricing, aided by control automation devices, can be integrated into the wholesale electricity market under various uncertainties through approximate dynamic programming. What distinguishes this study from the existing work in the literature is that whole- sale electricity prices are endogenously determined as we solve a system operator's economic dispatch problem on an hourly basis over the entire optimization horizon. This modeling and algorithm framework will allow a feedback loop between electricity prices and electricity consumption to be fully captured. While we are interested in a near-optimal solution using approximate dynamic programming; deterministic linear programming benchmarks are use to demonstrate the quality of our solutions. The other goal of the dissertation is to use this framework to provide numerical evidence to the debate on whether real-time pricing is superior than the current flat rate structure in terms of both economic and environmental impacts. For this purpose, the modeling and algorithm framework is tested on a large-scale test case with hundreds of power plants based on data available for California, making our findings useful for policy makers, system operators and utility companies to gain a concrete understanding on the scale of the impact with real-time pricing.

The Five-Factor Model of personality disorders (FFMPD; Widiger & Mullins-Sweatt, ) developed from the recognition that the popular Five-Factor Model (FFM) of personality could be used to describe and understand the official personality disorder (PD) constructs from the American Psychiatric Association's (APA) diagnostic manuals (e.g., DSM-IV-TR, APA, ). This article provides an overview of the FFM, highlighting its validity and utility in characterizing PDs as well as its ability to provide a comprehensive account of personality pathology in general. In 2013, DSM-5 is scheduled to appear, and the "hybrid" PD proposal will emphasize a 25-personality trait model. I present the current version of this new model, compare it to the FFMPD, and discuss issues related to the implementation of the FFMPD. © 2012 The Author.

2010-05-01

This study was conducted to assess the association of "diagnostic orphans" at baseline and subsequent development of Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV) alcohol use disorders (AUDs) 5 years later. A sample of 8,534 respondents was drawn from the National Longitudinal Survey of Youth for the years 1989 and 1994. Diagnostic orphans were defined as respondents who met one or two alcohol dependence symptom criteria but did not meet the criteria for a diagnosis of alcohol abuse or dependence. Using multinomial logistic regression analysis, 1994 assessments of DSM-IV AUD were regressed on 1989 baseline assessments of diagnostic orphan status and DSM-IV AUD. In addition to demographic characteristics, other background variables included heavy episodic drinking at baseline and early problem behaviors (antisocial behaviors, illicit substance use, and age at onset of alcohol use). Findings from this 5-year prospective study indicate that diagnostic orphan status at baseline was predictive of DSM-IV AUD at follow-up. These associations remained significant when other early behavioral problems were included in the models. The present findings have important diagnostic implications for the proposed DSM-V, particularly for a dimensional diagnosis incorporating less severe forms of alcohol dependence.

The best HVAC (heating, ventilating and air conditioning) subsystem to interface with the Engelhard fuel cell system for application in commercial buildings was determined. To accomplish this objective, the effects of several system and site specific parameters on the economic feasibility of fuel cell/HVAC systems were investigated. An energy flow diagram of a fuel cell/HVAC system is shown. The fuel cell system provides electricity for an electric water chiller and for domestic electric needs. Supplemental electricity is purchased from the utility if needed. An excess of electricity generated by the fuel cell system can be sold to the utility. The fuel cell system also provides thermal energy which can be used for absorption cooling, space heating and domestic hot water. Thermal storage can be incorporated into the system. Thermal energy is also provided by an auxiliary boiler if needed to supplement the fuel cell system output. Fuel cell/HVAC systems were analyzed with the TRACE computer program.

The re-labelling of dysthymic disorder to persistent depressive disorder in DSM-5: old wine in new bottles?

PubMed

Rhebergen, Didi; Graham, Rebecca

2014-01-01

Dysthymic disorder and other chronic depressive disorders have recently been merged in DSM-5 into a 'persistent depressive disorder' category. As its introduction in DSM-III, the validity of dysthymic disorder has long been challenged, posing concerns regarding the validity of its successor--persistent depressive disorder. This review aims to present recent findings regarding the validity and utility of dysthymic disorder. Several recent studies raise questions regarding the validity of dysthymic disorder, namely, results indicating a significant overlap between dysthymic disorder and other mood and/or anxiety disorders, failure of such a diagnosis to predict illness outcome and the lack of any validation strategy identifying that it is a depressive entity or subtype. Research findings indicate that dysthymic disorder is a heterogeneous diagnosis encompassing many different depressive (and anxiety or personality weighted) conditions, and without clear evidence of its validity as a diagnostic entity. As dysthymic disorder is a key component of DSM-defined persistent depressive disorder--the latter is at similar risk of providing a heterogeneous domain diagnosis, and thus limiting identification of specific causative factors and preferential treatment modality.

With the publication of DSM 5 alternative model for personality disorders it is critical to assess the components of the model against evidence-based models such as the five factor model and the DSM-IV-TR categorical model. This study explored the relative clinical utility of these models in screening for borderline personality disorder (BPD). Receiver operator characteristics and diagnostic efficiency statistics were calculated for three personality measures to ascertain the relative diagnostic efficiency of each measure. A total of 1653 adult inpatients at a specialist psychiatric hospital completed SCID-II interviews. Sample 1 (n=653) completed the SCID-II interviews, SCID-II Questionnaire (SCID-II-PQ) and the Big Five Inventory (BFI), while Sample 2 (n=1,000) completed the SCID-II interviews, Personality Inventory for DSM5 (PID-5) and the BFI. BFI measure evidenced moderate accuracy for two composites: High Neuroticism+ low agreeableness composite (AUC=0.72, SE=0.01, p<0.001) and High Neuroticism+ Low+Low Conscientiousness (AUC=0.73, SE=0.01, p<0.0001). The SCID-II-PQ evidenced moderate-to-excellent accuracy (AUC=0.86, SE=0.02, p<0.0001) with a good balance of specificity (SP=0.80) and sensitivity (SN=0.78). The PID-5 BPD algorithm (consisting of elevated emotional lability, anxiousness, separation insecurity, hostility, depressivity, impulsivity, and risk taking) evidenced moderate-to-excellent accuracy (AUC=0.87, SE=0.01, p<0.0001) with a good balance of specificity (SP=0.76) and sensitivity (SN=0.81). Findings generally support the use of SCID-II-PQ and PID-5 BPD algorithm for screening purposes. Furthermore, findings support the accuracy of the DSM 5 alternative model Criteria B trait constellation for diagnosing BPD. Limitations of the study include the single inpatient setting and use of two discrete samples to assess PID-5 and SCID-II-PQ. Copyright © 2017 Elsevier Inc. All rights reserved.

Renewable energy in electric utility capacity planning: a decomposition approach with application to a Mexican utility

DOE Office of Scientific and Technical Information (OSTI.GOV)

Staschus, K.

1985-01-01

In this dissertation, efficient algorithms for electric-utility capacity expansion planning with renewable energy are developed. The algorithms include a deterministic phase that quickly finds a near-optimal expansion plan using derating and a linearized approximation to the time-dependent availability of nondispatchable energy sources. A probabilistic second phase needs comparatively few computer-time consuming probabilistic simulation iterations to modify this solution towards the optimal expansion plan. For the deterministic first phase, two algorithms, based on a Lagrangian Dual decomposition and a Generalized Benders Decomposition, are developed. The probabilistic second phase uses a Generalized Benders Decomposition approach. Extensive computational tests of the algorithms aremore » reported. Among the deterministic algorithms, the one based on Lagrangian Duality proves fastest. The two-phase approach is shown to save up to 80% in computing time as compared to a purely probabilistic algorithm. The algorithms are applied to determine the optimal expansion plan for the Tijuana-Mexicali subsystem of the Mexican electric utility system. A strong recommendation to push conservation programs in the desert city of Mexicali results from this implementation.« less

Electromagnetic interference of power conditioners for solar electric propulsion

1973-01-01

Electrical, multikilowatt power conditioning (PC) equipment needed on board a spacecraft utilizing solar electric propulsion creates an electromagnetic environment that is potentially deterimental to the science, navigation, and radio communication hardware. Within the scope of the solar electric propulsion system technology program, three lightweight, 2.5-kW PCs were evaluated in terms of their electromagnetic characteristics. It was found that the levels of radiated and conducted interference exceeded the levels anticipated for a solar electric propulsion mission. These noise emissions, however, were the result of deficient interference design in these models, rather than a basic inability to control interference in this type of PC.

American Recovery and Reinvestment Act of 2009: Final Report on Customer Acceptance, Retention, and Response to Time-Based Rates from Consumer Behavior Studies

DOE Office of Scientific and Technical Information (OSTI.GOV)

Cappers, Peter; Scheer, Rich

Time-based rate programs, enabled by utility investments in advanced metering infrastructure (AMI), are increasingly being considered by utilities as tools to reduce peak demand and enable customers to better manage consumption and costs. Under the Smart Grid Investment Grant Program (SGIG), the U.S. Department of Energy (DOE) partnered with several electric utilities to conduct consumer behavior studies (CBS). The goals involved applying randomized and controlled experimental designs for estimating customer responses more precisely and credibly to advance understanding of time-based rates and customer systems, and provide new information for improving program designs, implementation strategies, and evaluations. The intent was tomore » produce more robust and credible analysis of impacts, costs, benefits, and lessons learned and assist utility and regulatory decision makers in evaluating investment opportunities involving time-based rates.« less

Economic development in the United States depends on a reliable and affordable power supply. The nation will need well educated engineers to design a modern, safe, secure, and reliable power grid for our future needs. An anticipated shortage of qualified engineers has caused considerable concern in many professional circles, and various steps are being taken nationwide to alleviate the potential shortage and ensure the North American power system's reliability, and our world-wide economic competitiveness. To help provide a well-educated and trained workforce which can sustain and modernize the nation's power grid, Gonzaga University's School of Engineering and Applied Science hasmore » established a five-course (15-credit hour) Certificate Program in Transmission and Distribution (T&D) Engineering. The program has been specifically designed to provide working utility engineering professionals with on-line access to advanced engineering courses which cover modern design practice with an industry-focused theoretical foundation. A total of twelve courses have been developed to-date and students may select any five in their area of interest for the T&D Certificate. As each course is developed and taught by a team of experienced engineers (from public and private utilities, consultants, and industry suppliers), students are provided a unique opportunity to interact directly with different industry experts over the eight weeks of each course. Course material incorporates advanced aspects of civil, electrical, and mechanical engineering disciplines that apply to power system design and are appropriate for graduate engineers. As such, target students for the certificate program include: (1) recent graduates with a Bachelor of Science Degree in an engineering field (civil, mechanical, electrical, etc.); (2) senior engineers moving from other fields to the utility industry (i.e. paper industry to utility engineering or project management positions); and (3) regular working professionals wishing to update their skills or increase their knowledge of utility engineering design practices and procedures. By providing graduate educational opportunities for the above groups, the T&D Program will help serve a strong industry need for training the next generation of engineers in the cost-effective design, construction, operation, and maintenance of modern electrical transmission and distribution systems. In addition to developing the on-line engineering courses described above, the T&D Program also focused significant efforts towards enhancing the training opportunities available to power system operators in the northwest. These efforts have included working with outside vendors to provide NERC-approved training courses in Gonzaga University's (GU) system operator training facility, support for an accurate system model which can be used in regional blackstart exercises, and the identification of a retired system operator who could provide actual regional training courses. The GU system operator training facility is also being used to recruit young workers, veterans, and various under-represented groups to the utility industry. Over the past three years students from Columbia Gorge Community College, Spokane Falls Community College, Walla Walla Community College, Central Washington University, Eastern Washington University, Gonzaga University, and various local high schools have attended short (one-day) system operator training courses free of charge. These collaboration efforts has been extremely well received by both students and industry, and meet T&D Program objectives of strengthening the power industry workforce while bridging the knowledge base across power worker categories, and recruiting new workers to replace a predominantly retirement age workforce. In the past three years the T&D Program has provided over 170 utility engineers with access to advanced engineering courses, been involved in training more than 300 power system operators, and provided well over 500 college and high school students with an experience in running a power system simulator and an exposure to various utility-related professions and craft trades.« less

Schizoaffective Disorder in the DSM-5.

Characterization of patients with both psychotic and mood symptoms, either concurrently or at different points during their illness, has always posed a nosological challenge and this is reflected in the poor reliability, low diagnostic stability, and questionable validity of DSM-IV Schizoaffective Disorder. The clinical reality of the frequent co-occurrence of psychosis and Mood Episodes has also resulted in over-utilization of a diagnostic category that was originally intended to only rarely be needed. In the Diagnostic and Statistical Manual of Mental Disorders, fifth edition, an effort is made to improve reliability of this condition by providing more specific criteria and the concept of Schizoaffective Disorder shifts from an episode diagnosis in DSM-IV to a life-course of the illness in DSM-5. When psychotic symptoms occur exclusively during a Mood Episode, DSM-5 indicates that the diagnosis is the appropriate Mood Disorder with Psychotic Features, but when such a psychotic condition includes at least a two-week period of psychosis without prominent mood symptoms, the diagnosis may be either Schizoaffective Disorder or Schizophrenia. In the DSM-5, the diagnosis of Schizoaffective Disorder can be made only if full Mood Disorder episodes have been present for the majority of the total active and residual course of illness, from the onset of psychotic symptoms up until the current diagnosis. In earlier DSM versions the boundary between Schizophrenia and Schizoaffective Disorder was only qualitatively defined, leading to poor reliability. This change will provide a clearer separation between Schizophrenia with mood symptoms from Schizoaffective Disorder and will also likely reduce rates of diagnosis of Schizoaffective Disorder while increasing the stability of this diagnosis once made.

Grilo, Carlos M.; Ivezaj, Valentina; White, Marney A.

2015-01-01

Research has examined various aspects of the diagnostic criteria for binge-eating disorder (BED) but has yet to evaluate the DSM-5 severity criterion. This study examined the DSM-5 severity criterion for BED based on binge-eating frequency and tested an alternative severity specifier based on overvaluation of shape/weight. 338 community volunteers categorized with DSM-5 BED completed a battery of self-report instruments. Participants were categorized first using DSM-5 severity levels and second by shape/weight overvaluation and were compared on clinical variables. 264 (78.1%) participants were categorized as mild, 67 (19.8%) as moderate, 6 (1.8%) as severe, and 1 (0.3%) as extreme. Analyses comparing mild and moderate severity groups revealed no significant differences in demographic variables or BMI; moderate severity group had greater eating-disorder psychopathology (small effect-sizes) but not depression than mild group. Participants with overvaluation (N=196; 60.1%) versus without (N=130; 39.9%) did not differ significantly in age, sex, BMI, or binge-eating frequency. Overvaluation group had significantly greater eating-disorder psychopathology and depression than non-overvaluation group. The greater eating-disorder and depression levels (medium-to-large effect-sizes) persisted after adjusting for ethnicity/race and binge-eating severity/frequency, without attenuation of effect-sizes. Findings from this non-clinical community sample provide support for overvaluation of shape/weight as a specifier for BED as it provides stronger information about severity than the DSM-5 rating based on binge-eating. Future research should include treatment-seeking patients with BED to test the utility of DSM-5 severity specifiers and include broader clinical validators. PMID:25701802

DSM-IV Antisocial Personality Disorder and Conduct Disorder: Evidence for Taxonic Structures Among Individuals With and Without Substance Use Disorders in the General Population

Kerridge, Bradley T; Saha, Tulshi D; Hasin, Deborah S

2014-01-01

Objective: The categorical-dimensional status of DSM-IV (Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition) conduct disorder (CD) and antisocial personality disorder (ASPD) is a source of controversy. This study examined whether the underlying structure of DSM-IV CD and ASPD was dimensional or categorical (taxonic) among individuals with and without substance use disorders. Method: Using a national large representative survey of U.S. adults (n = 43,093), taxometric analyses of DSM-IV CD and ASPD diagnostic criteria were conducted on the total sample and among those with and without substance use disorders. Results: Results of three taxometric procedures were consistent in showing that the structures underlying DSM-IV CD and ASPD were clearly taxonic in the total sample and among individuals with and without substance use disorders. Comparison curve fit indices exceeded 0.57 for each model. Conclusions: Taxonic findings of the present study were in contrast to the dimensional results of prior taxometric research among incarcerated samples with substantial comorbidity of antisocial syndromes and substance use disorders. Results supported the categorical representation and diagnostic thresholds of ASPD and CD as defined in DSM-IV and DSM-5. That the structure of ASPD and CD may be taxonic suggests that further research on these disorders use group comparative designs in which samples with and without these disorders are compared in terms of sociodemographic and clinical correlates, comorbidity, and treatment utilization. The taxonic structure of ASPD and CD may contribute to future research on causal processes through which these antisocial syndromes develop. PMID:24766762

Satchwell, Andrew; Cappers, Peter; Goldman, Charles

2011-03-22

Energy efficiency resource standards (EERS) are a prominent strategy to potentially achieve rapid and aggressive energy savings goals in the U.S. As of December 2010, twenty-six U.S. states had some form of an EERS with savings goals applicable to energy efficiency (EE) programs paid for by utility customers. The European Union has initiated a similar type of savings goal, the Energy End-use Efficiency and Energy Services Directive, where it is being implemented in some countries through direct partnership with regulated electric utilities. U.S. utilities face significant financial disincentives under traditional regulation which affects the interest of shareholders and managers inmore » aggressively pursuing cost-effective energy efficiency. Regulators are considering some combination of mandated goals ('sticks') and alternative utility business model components ('carrots' such as performance incentives) to align the utility's business and financial interests with state and federal energy efficiency public policy goals. European countries that have directed their utilities to administer EE programs have generally relied on non-binding mandates and targets; in the U.S., most state regulators have increasingly viewed 'carrots' as a necessary condition for successful achievement of energy efficiency goals and targets. In this paper, we analyze the financial impacts of an EERS on a large electric utility in the State of Arizona using a pro-forma utility financial model, including impacts on utility earnings, customer bills and rates. We demonstrate how a viable business model can be designed to improve the business case while retaining sizable ratepayer benefits. Quantifying these concerns and identifying ways they can be addressed are crucial steps in gaining the support of major stakeholder groups - lessons that can apply to other countries looking to significantly increase savings targets that can be achieved from their own utility-administered EE programs.« less

The Impact of DSM-5 on Eating Disorder Diagnoses.

2017-05-01

Eating disorder diagnostic criteria were revised from the fourth to the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV and -5, respectively). This study examines the impact of these revisions on rates of eating disorder diagnoses in treatment-seeking youth. Participants were 651 youth, ages 7-18 years, presenting to an outpatient eating disorders program who met criteria for a DSM-IV eating disorder diagnosis on intake. Patients completed well-validated semi-structured interviews to assess eating disorder psychopathology and psychiatric comorbidity. Participants were predominantly female (n = 588; 90.3%) with an average age of 15.28 years (SD = 2.21), mean percent of median Body Mass Index (mBMI) of 101.91 (SD = 31.73), and average duration of illness of 16.74 months (SD = 17.63). Cases of DSM-IV Eating Disorder Not Otherwise Specified (EDNOS), now most consistent with DSM-5 Other Specified Feeding or Eating Disorder, decreased from 47.6% to 39.0%, Anorexia Nervosa increased from 29.6% to 33.5%, and Bulimia Nervosa increased from 22.7% to 24.7%. Consistent with previous studies, and in keeping with the aims of the DSM-5 for eating disorders, the revised diagnostic criteria reduced cases of DSM-IV EDNOS and increased cases of specified eating disorders. © 2016 Wiley Periodicals, Inc.(Int J Eat Disord 2017; 50:578-581). © 2016 Wiley Periodicals, Inc.

2013-01-01

Objective To investigate factors hypothesized to moderate the effects of a dissonance-based eating disorder prevention program, including initial elevations in thin-ideal internalization, body dissatisfaction, eating disorder symptoms, and older participant age. Method Adolescent female high school and college students with body image concerns (N = 977; M age = 18.6) were randomized to a dissonance-based thin-ideal internalization reduction program or an assessment-only control condition in three prevention trials. Results The intervention produced (a) significantly stronger reductions in thin-ideal internalization for participants with initial elevations in thin-ideal internalization and a threshold/subthreshold DSM-5 eating disorder at baseline, (b) significantly greater reductions in eating disorder symptoms for participants with versus without a DSM-5 eating disorder at baseline, and (c) significantly stronger reductions in body dissatisfaction for late adolescence/young adulthood versus mid-adolescent participants. Baseline body dissatisfaction did not moderate the intervention effects. Conclusion Overall, intervention effects tended to be amplified for individuals with initial elevations in risk factors and a DSM-5 eating disorder at baseline. Results suggest that this prevention program is effective for a broad range of individuals, but is somewhat more beneficial for the subgroups identified in the moderation analyses. PMID:23337181

Deregulation strategies for local governments and the role/opportunities for energy efficiency services in the utility industry deregulation

DOE Office of Scientific and Technical Information (OSTI.GOV)

Tseng, P.C.

As the future shape of the electric utility industry continues to unfold and as retail competition becomes a reality, local governments are faced with balancing the need for: (1) economic development; (2) and to avoid the potential impact of cost-shifting among residents and businesses, while ensuring reliable and universal energy services. Furthermore, local governments need to find ways to recoup potential loss of franchise and tax revenues, to ensure fair and adequate energy-efficiency programs, and to continue other social programs for low income families. This paper will address two important issues every local government in the US are facing: (1)more » the development of viable deregulation strategies before, during and after the promulgation of utility deregulation; (2) opportunities for energy efficiency services in the competitive markets to serve local governments, which typically constitutes the largest market segment in utility's service territory. This paper presents issues and challenges common to all local governments. It documents strategies that several local governments are utilizing to embrace the coming electric utility restructuring and competition challenge to the benefits of their respective communities. This paper presents the results on deregulation work by the City of Portland, Oregon, Barnstable County, Massachusetts, and Montgomery County, Maryland.

The state agency with principal authority to regulate electric public utilities is the Power Review Board (Board). However, the Board in fact, exercised little regulatory authority over heat and power utilities because all electrical power in Nebraska is currently supplied by public authorities and is not subject to regulation by the Board. Gas and water utilities are also subject to general supervision by municipalities. The Board is compised of five members - an attorney, an engineer, one accountant, two lay - persons appointed by the governor and confirmed by the legislature. All members are appointed to overlapping four-year terms, andmore » none may serve more than two consecutive terms. Decisions by the Board require the approval of a majority of its members. The Public Service Commission of Nebraska is a constitutionally created body. Its powers and duties include the regulation of rates, service, and general control of common carriers as the legislature may provide by law. Other state agencies also possess limited regulatory jurisdiction which may be relevant to an energy facility. Public utility regulatory statutes, energy facility siting programs, and municipal franchising authority are examined to identify how they may impact on the ability of an organization, whether or not it be a regulated utility, to construct and operate an ICES.« less

In the past 20 years, much evidence has accumulated against the overly restrictive diagnostic concepts of hypomania in DSM-IV and DSM-IV-TR. We tested DSM-IV-TR and a broader modified version (DSM-IV-TRm) for their ability to detect bipolarity in patients who had been treated for bipolar disorders (BD) in psychiatric settings, and who now consulted general practitioners (GPs) for new major depressive episodes (MDE). Bipolact II was an observational, single-visit survey involving 390 adult patients attending primary care for MDE (DSM-IV-TR criteria) in 201 GP offices in France. The participating GPs (53.3 ± 6.5 years old, 80.1% male) were trained by the Bipolact Educational Program, and were familiar with the medical care of depressive patients. Of the 390 patients with MDE, 129 (33.1%) were previously known as bipolar patients (ICD-10 criteria). Most of the latter bipolar patients (89.7%) had previously been treated with antidepressants. Only 9.3% of them met DMS-IV-TR criteria for BD. Conversely, 79.1% of the 129 bipolar patients met DMS-IV-TRm criteria for BD and showed strong associations with impulse control disorders and manic/hypomanic switches during antidepressant treatment. Limited training of participating GPs, recall bias of patients, and the study not being representative for untreated bipolar patients. Very few ICD-10 bipolar patients consulting French GPs for MDE met DSM-IV-TR criteria for bipolar diagnosis, which suggests that DSM-IV-TR criteria are insufficient and too restrictive for the diagnosis of BD. DSM-IV-TRm was more sensitive, but 20% of bipolar patients were undetected. © 2013 Elsevier B.V. All rights reserved.

Is DSM-IV criterion A2 associated with PTSD diagnosis and symptom severity?

PubMed

Osei-Bonsu, Princess E; Spiro, Avron; Schultz, Mark R; Ryabchenko, Karen A; Smith, Eric; Herz, Lawrence; Eisen, Susan V

2012-08-01

The diagnostic criteria for posttraumatic stress disorder (PTSD) have received significant scrutiny. Several studies have investigated the utility of Criterion A2, the subjective emotional response to a traumatic event. The American Psychiatric Association (APA) has proposed elimination of A2 from the PTSD diagnostic criteria for DSM-5; however, there is mixed support for this recommendation and few studies have examined A2 in samples at high risk for PTSD such as veterans. In the current study of 908 veterans who screened positive for a traumatic event, A2 was not significantly associated with having been told by a doctor that the veteran had PTSD. Those who endorsed A2, however, reported greater PTSD symptom severity in the 3 DSM-IV symptom clusters of reexperiencing (d = 0.45), avoidance (d = 0.61), and hyperarousal (d = 0.44), and A2 was significantly associated with PTSD symptom severity for all 3 clusters (R(2) = .25, .25, and .27, respectively) even with trauma exposure in the model. Thus, although A2 may not be a necessary criterion for PTSD diagnosis, its association with PTSD symptom severity warrants further exploration of its utility. Published 2012.

The six most essential questions in psychiatric diagnosis: a pluralogue part 1: conceptual and definitional issues in psychiatric diagnosis

PubMed Central

2012-01-01

In face of the multiple controversies surrounding the DSM process in general and the development of DSM-5 in particular, we have organized a discussion around what we consider six essential questions in further work on the DSM. The six questions involve: 1) the nature of a mental disorder; 2) the definition of mental disorder; 3) the issue of whether, in the current state of psychiatric science, DSM-5 should assume a cautious, conservative posture or an assertive, transformative posture; 4) the role of pragmatic considerations in the construction of DSM-5; 5) the issue of utility of the DSM - whether DSM-III and IV have been designed more for clinicians or researchers, and how this conflict should be dealt with in the new manual; and 6) the possibility and advisability, given all the problems with DSM-III and IV, of designing a different diagnostic system. Part I of this article will take up the first two questions. With the first question, invited commentators express a range of opinion regarding the nature of psychiatric disorders, loosely divided into a realist position that the diagnostic categories represent real diseases that we can accurately name and know with our perceptual abilities, a middle, nominalist position that psychiatric disorders do exist in the real world but that our diagnostic categories are constructs that may or may not accurately represent the disorders out there, and finally a purely constructivist position that the diagnostic categories are simply constructs with no evidence of psychiatric disorders in the real world. The second question again offers a range of opinion as to how we should define a mental or psychiatric disorder, including the possibility that we should not try to formulate a definition. The general introduction, as well as the introductions and conclusions for the specific questions, are written by James Phillips, and the responses to commentaries are written by Allen Frances.

This study examined transdiagnostic features of generalized anxiety disorder (GAD) and dysthymia in an outpatient clinical sample. Fifteen patients who met DSM-IV criteria for GAD and twenty-one patients who met DSM-IV criteria for dysthymia but who did not have comorbid anxiety disorder were evaluated utilizing the Rorschach. Salient clinical variables were then compared. Results showed that patients with GAD scored significantly higher on variables related to cognitive agitation and a desire/need for external soothing. In addition, there was a trend for patients with GAD to produce higher scores on a measure of ruminative focus on negative aspects of the self. Thus, not surprisingly, GAD patients' experienced more distress than the dysthymic patients. The implications of these findings are discussed with regards to better understanding the shared and distinct features of GAD and dysthymia. Copyright © 2016 Elsevier Ireland Ltd.

2016-08-26

The Better Buildings Energy Data Accelerator (BBEDA) is a unique effort that has supported 22 pairs of local governments and their utility companies to help building owners gain access to their whole-building energy data. Municipal and Utility BBEDA Partners committed to develop streamlined and easy-to-use solutions to provide whole-building energy data, especially for multitenant commercial buildings, by the end of 2015. As a result, building owners would be able to make data-driven decisions about their buildings by utilizing readily available energy consumption data for entire buildings. Traditionally, data access was difficult to implement due to technical barriers and the lackmore » of clear value propositions for the utilities. During the past two years, BBEDA has taken a hands-on approach to overcome these barriers by offering a platform for the partners to discuss their challenges and solutions. Customized support was also provided to Partners building their local strategies. Based on the lessons learned from the partners, BBEDA developed a final toolkit with guiding documents that addressed key barriers and served as a resource for the other cities and utilities attempting to establish whole-building data access, including an exploration of opportunities to apply the whole-building data to various aspects of utility demand-side management (DSM) programs. BBEDA has been a catalyst for market transformation by addressing the upstream (to efficiency implementation) barrier of data access, demonstrated through the success of the BBEDA partners to address policy, engagement, and technical hurdles and arrive at replicable solutions to make data access a standard practice nationwide. As a result of best practices identified by the BBEDA, 18 utilities serving more than 2.6 million commercial customers nationwide will provide whole-building energy data access to building owners by 2017. This historic expansion of data accessibility will increase building energy benchmarking, the first step many building owners take to improve the energy efficiency of their buildings.« less

2018-04-15

Despite its demonstrated empirical superiority over the DSM-5 Section 2 categorical model of personality disorders for organizing the features of personality pathology, limitations remain with regard to the translation of the DSM-5 Section 3 alternative model of personality disorders (AMPD) to clinical practice. The goal of this paper is to outline a general and preliminary framework for approaching treatment from the perspective of the AMPD. Specific techniques are discussed for the assessment and treatment of both Criterion A personality dysfunction and Criterion B maladaptive traits. A concise and step-by-step model is presented for clinical decision making with the AMPD, in the hopes of offering clinicians a framework for treating personality pathology and promoting further research on the clinical utility of the AMPD.

Grilo, C M

2004-01-01

This study examined the diagnostic efficiency of the DSM-IV criteria for obsessive compulsive personality disorder (OCPD) in patients with binge eating disorder (BED). Two hundred and eleven consecutive adult patients with axis I diagnoses of BED were reliably assessed with semi-structured diagnostic interviews. Conditional probabilities-sensitivity, specificity, positive predictive power (PPP), and negative predictive power (NPP)-were calculated for each of the eight criteria for OCPD, using the 'best-estimate' OCPD diagnosis as the standard. The diagnostic efficiencies of the OCPD criteria were variable, with three criteria failing to have predictive value (PPP<0.50). The best inclusion criterion (highest PPP) was 'Perfectionism,' which was also the overall most predictive criterion. The findings suggest ordering of the DSM-IV criteria for OCPD based on performance and call into question the utility of some criteria.

There is growing interest in policies, programs and tariffs that encourage customer loads to provide demand response (DR) to help discipline wholesale electricity markets. Proposals at the retail level range from eliminating fixed rate tariffs as the default service for some or all customer groups to reinstituting utility-sponsored load management programs with market-based inducements to curtail. Alternative rate designs include time-of-use (TOU), day-ahead real-time pricing (RTP), critical peak pricing, and even pricing usage at real-time market balancing prices. Some Independent System Operators (ISOs) have implemented their own DR programs whereby load curtailment capabilities are treated as a system resource andmore » are paid an equivalent value. The resulting load reductions from these tariffs and programs provide a variety of benefits, including limiting the ability of suppliers to increase spot and long-term market-clearing prices above competitive levels (Neenan et al., 2002; Boren stein, 2002; Ruff, 2002). Unfortunately, there is little information in the public domain to characterize and quantify how customers actually respond to these alternative dynamic pricing schemes. A few empirical studies of large customer RTP response have shown modest results for most customers, with a few very price-responsive customers providing most of the aggregate response (Herriges et al., 1993; Schwarz et al., 2002). However, these studies examined response to voluntary, two-part RTP programs implemented by utilities in states without retail competition.1 Furthermore, the researchers had limited information on customer characteristics so they were unable to identify the drivers to price response. In the absence of a compelling characterization of why customers join RTP programs and how they respond to prices, many initiatives to modernize retail electricity rates seem to be stymied.« less

Permanent draft genome sequence of Desulfurococcus mobilis type strain DSM 2161, a thermoacidophilic sulfur-reducing crenarchaeon isolated from acidic hot springs of Hveravellir, Iceland.

This report presents the permanent draft genome sequence of Desulfurococcus mobilis type strain DSM 2161, an obligate anaerobic hyperthermophilic crenarchaeon that was isolated from acidic hot springs in Hveravellir, Iceland. D. mobilis utilizes peptides as carbon and energy sources and reduces elemental sulfur to H2S. A metabolic construction derived from the draft genome identified putative pathways for peptide degradation and sulfur respiration in this archaeon. Existence of several hydrogenase genes in the genome supported previous findings that H2 is produced during the growth of D. mobilis in the absence of sulfur. Interestingly, genes encoding glucose transport and utilization systems also exist in the D. mobilis genome though this archaeon does not utilize carbohydrate for growth. The draft genome of D. mobilis provides an additional mean for comparative genomic analysis of desulfurococci. In addition, our analysis on the Average Nucleotide Identity between D. mobilis and Desulfurococcus mucosus suggested that these two desulfurococci are two different strains of the same species.

In this paper, we examine how the management of prostate cancer lends itself to a disease state management (DSM)-based approach, and propose a framework that emphasizes the patient-provider-caregiver triad in managing the long-term implications of the condition. There is often no clearly superior approach to the management of patients with prostate cancer (eg, watchful waiting and hormonal therapy), and each option entails different trade-offs in quality of life. Ideally, the physician and patient discuss the options, issues, and patient preferences for treatment through the shared decision-making process. A family caregiver such as the spouse of the patient is often involved in the treatment decision and in the long-term management of the cancer experience. In order to develop a DSM program supporting both patient and caregiver, educational, psychosocial, and health care system support needs should be tailored to each phase of cancer treatment/management. To embrace the unique aspects of prostate cancer management, the proposed framework emphasizes communication among the patient-caregiver-provider triad, inclusion of family caregivers in the program, cancer phase-specific support, and psychosocial services as a basis for implementation and evaluation of a DSM program in prostate cancer.

Home health care agencies are increasingly taking care of sicker, older patients with greater comorbidities. However, they are unequipped to appropriately manage these older adults, particular persons living with dementia (PLWD). We therefore developed the Dementia Symptom Management at Home (DSM-H) Program, a bundled interprofessional intervention, to improve the care confidence of providers, and quality of care delivered to PLWD and their caregivers. We implemented the DSM-H with 83 registered nurses, physical therapists, and occupational therapists. Overall, there was significant improvement in pain knowledge (5.9%) and confidence (26.5%), depression knowledge (14.8%) and confidence (36.1%), and neuropsychiatric symptom general knowledge (16.8%), intervention knowledge (20.9%), attitudes (3.4%) and confidence (27.1%) at a statistical significance of (P < .0001). We also found significant differences between disciplines. Overall, this disseminable program proved to be implementable and improve clinician's knowledge and confidence in caring for PLWD, with the potential to improve quality of care and quality of life, and decrease costs.

1989-03-01

Program planning for advanced battery energy storage technology is supported within the NEMO Program. Specifically this study had focused on the review of advanced battery applications; the development and demonstration status of leading battery technologies; and potential marketing opportunity. Advanced secondary (or rechargeable) batteries have been under development for the past two decades in the U.S., Japan, and parts of Europe for potential applications in electric utilities and for electric vehicles. In the electric utility applications, the primary aim of a battery energy storage plant is to facilitate peak power load leveling and/or dynamic operations to minimize the overall power generation cost. In the application for peak power load leveling, the battery stores the off-peak base load energy and is discharged during the period of peak power demand. This allows a more efficient use of the base load generation capacity and reduces the need for conventional oil-fired or gas-fire peak power generation equipment. Batteries can facilitate dynamic operations because of their basic characteristics as an electrochemical device capable of instantaneous response to the changing load. Dynamic operating benefits results in cost savings of the overall power plant operation. Battery-powered electric vehicles facilitate conservation of petroleum fuel in the transportation sector, but more importantly, they reduce air pollution in the congested inner cities.

The impact of electric vehicles on the Southern California Edison System. Final report

This report describes the results of the first phase of an investigation of the impacts of electric vehicles (EVs) in southern California. The investigation focuses on the Southern California Edison Company (SCE) which provides electric service for approximately 60% of southern California. The project is supported by the ``Air Quality Impacts of Energy Efficiency`` Program of the California Institute for Energy Efficiency (CIEE). The first phase of the research is organized around how EVs might be viewed by customers, vehicle manufacturers and electric utility companies. The vehicle manufacturers` view has been studied with special emphasis on the role of marketablemore » permit systems. The utilities` view of EVs is the subject of this report. The review is particularly important as several case studies of EVs in southern California have been conducted in recent years. The dynamics of a growing population of EVs is explained. Chapter 5 explains a simple method of deriving the electricity demands which could result from the operation of EVs in southern California. The method is demonstrated for several simple examples and then used to find the demands associated with each of the eight EV scenarios. Chapter 6 reports the impacts on SCE operations from the new demands for electricity. Impacts are summarized in terms of system operating costs, reliability of service, and changes in the utility`s average electric rate. Chapter 7 turns to the emissions of air pollutants released by the operation of EVs, conventional vehicles (CVs) and power plants. Chapter 8 takes the air pollution analysis one step further by examining the possible reduction in ambient ozone concentration in southern California.« less

Changes in the pattern of electric power consumption in India have influenced energy utilization processes and socio-economic development to greater extent during the last few decades. Assessment of spatial distribution of electricity consumption is, thus, essential for projecting availability of energy resource and planning its infrastructure. This paper makes an attempt to model the future electricity demand for sustainable energy and its management in India. The nighttime light database provides a good approximation of availability of energy. We utilized defense meteorological satellite program-operational line-scan system (DMSP-OLS) nighttime satellite data, electricity consumption (1993-2013), gross domestic product (GDP) and population growth to construct the model. We also attempted to examine the sensitiveness of electricity consumption to GDP and population growth. The results revealed that the calibrated DMSP and model has provided realistic information on the electric demand with respect to GDP and population, with a better accuracy of r 2  = 0.91. The electric demand was found to be more sensitive to GDP (r = 0.96) than population growth (r = 0.76) as envisaged through correlation analysis. Hence, the model proved to be useful tool in predicting electric demand for its sustainable use and management.

Design, Fabrication, and Testing of Emissive Probes to Determine the Plasma Potential of the Plumes of Various Electric Thrusters

NASA Technical Reports Server (NTRS)

Chen, Erinna M.

2005-01-01

A significant problem in the use of electric thrusters in spacecraft is the formation of low-energy ions in the thruster plume. Low-energy ions are formed in the plume via random collisions between high-velocity ions ejected from the thruster and slow-moving neutral atoms of propellant effusing from the engine. The sputtering of spacecraft materials due to interactions with low-energy ions may result in erosion or contamination of the spacecraft. The trajectory of these ions is determined primarily by the plasma potential of the plume. Thus, accurate characterization of the plasma potential is essential to predicting low-energy ion contamination. Emissive probes were utilized to determine the plasma potential. When the ion and electron currents to the probe are balanced, the potential of such probes float to the plasma potential. Two emissive probes were fabricated; one utilizing a DC power supply, another utilizing a rectified AC power source. Labview programs were written to coordinate and automate probe motion in the thruster plume. Employing handshaking interaction, these motion programs were synchronized to various data acquisition programs to ensure precision and accuracy of the measurements. Comparing these experimental values to values from theoretical models will allow for a more accurate prediction of low-energy ion interaction.

Using aerial infrared thermography to detect utility theft of service

NASA Astrophysics Data System (ADS)

Stockton, Gregory R.; Lucas, R. Gillem

2012-06-01

Natural gas and electric utility companies, public utility commissions, consumer advocacy groups, city governments, state governments and the federal government United States continue to turn a blind eye towards utility energy theft of service which we conservatively estimate is in excess of 10 billion a year. Why? Many in the United States have exhausted their unemployment benefits. The amounts for federal funding for low income heating assistance programs (LIHEAP) funds were cut by nearly 40% for 2012 to 3.02 billion. "At peak funding ($5.1 billion in 2009), the program was national in scale but still only had enough resources to support roughly 1/4 of the eligible households.i" Contributions to charities are down and the number of families below the poverty line who are unable to pay to heat their houses continues to rise. Many of the less fortunate in our society now consider theft and fraud to be an attractive option for their supply of natural gas and/or electricity. A record high mild winter in 2011-2012 coupled with 10-year low natural gas prices temporarily obscured the need for low income heating assistance programs (LIHEAPs) from the news and federal budgets, but cold winters will return. The proliferation of smart meters and automated meter infrastructures across our nation can do little to detect energy theft because the thieves can simply by-pass the meters, jumper around the meters and/or steal meters from abandoned houses and use them. Many utility systems were never set-up to stop these types of theft. Even with low-cost per identified thief method using aerial infrared thermography, utilities continue to ignore theft detection.

The "voluntary" or "green power" market is that in which consumers and institutions voluntarily purchase renewable energy to match all or part of their electricity needs. Voluntary action provides a revenue stream for renewable energy projects and raises consumer awareness of the benefits of renewable energy. There are numerous ways consumers and institutions can purchase renewable energy. Historically, the voluntary market has consisted of three market sectors: (1) utility green pricing programs (in states with regulated electricity markets), (2) competitive suppliers (in states with restructured electricity markets), and (3) unbundled renewable electricity certificate (REC) markets, where RECs are purchased bymore » consumers separately from electricity ("unbundled").« less

This study aimed to assess the validity and reliability of the Turkish version of the Diagnostic and statistical manual of Mental Disorders. (5 th ed.) (DSM-5) Social Anxiety Disorder Severity Scale- Child Form. The scale was prepared by carrying out the translation and back translation of the DSM-5 Social Anxiety Disorder Severity Scale - Child Form. The study group consisted of 31 patients that had been treated in a child psychiatry unit and diagnosed with social anxiety disorder and 99 healthy volunteers that were attending middle or high school during the study period. For the assessment, the Screen for Child Anxiety and Related Emotional Disorders (SCARED) was also used along with the DSM-5 Social Anxiety Disorder Severity Scale - Child Form. Regarding reliability analyses, Cronbach's alpha internal consistency coefficient was calculated as 0.941, while item-total score correlation coefficients were measured between 0.566 and 0.866. A test-retest correlation coefficient was calculated as r=0.711. As for construct validity, one factor that could explain 66.0 % of the variance was obtained. As for concurrent validity, the scale showed a high correlation with the SCARED. It was concluded that the Turkish version of the DSM-5 Social Anxiety Disorder Severity Scale - Child Form could be utilized as a valid and reliable tool both in clinical practice and for research purposes.

Measures of the DSM-5 mixed-features specifier of major depressive disorder.

PubMed

Zimmerman, Mark

2017-04-01

During the past two decades, a number of studies have found that depressed patients frequently have manic symptoms intermixed with depressive symptoms. While the frequency of mixed syndromes are more common in bipolar than in unipolar depressives, mixed states are also common in patients with major depressive disorder. The admixture of symptoms may be evident when depressed patients present for treatment, or they may emerge during ongoing treatment. In some patients, treatment with antidepressant medication might precipitate the emergence of mixed states. It would therefore be useful to systematically inquire into the presence of manic/hypomanic symptoms in depressed patients. We can anticipate that increased attention will likely be given to mixed depression because of changes in the DSM-5. In the present article, I review instruments that have been utilized to assess the presence and severity of manic symptoms and therefore could be potentially used to identify the DSM-5 mixed-features specifier in depressed patients and to evaluate the course and outcome of treatment. In choosing which measure to use, clinicians and researchers should consider whether the measure assesses both depression and mania/hypomania, assesses all or only some of the DSM-5 criteria for the mixed-features specifier, or assesses manic/hypomanic symptoms that are not part of the DSM-5 definition. Feasibility, more so than reliability and validity, will likely determine whether these measures are incorporated into routine clinical practice.

Power for all? Electricity and uneven development in North Carolina

NASA Astrophysics Data System (ADS)

Harrison, Conor M.

Many towns in eastern North Carolina face a number of challenges common to the rural South, including high rates of poverty and diminishing employment opportunities. However, some residents of this region also confront a unique hardship---electricity prices that are vastly higher than those of surrounding areas. This dissertation examines the origins of pricing inequalities in the electricity market of eastern North Carolina---namely how such inequalities developed and their role in the production of racial and economic disparities in the South. This dissertation examines the evolving relations between federal and state agencies, corporations, and electric utilities, and asks why these interactions produced varying social outcomes across different places and spatial settings. The research focuses on the origins and subsequent development of electric utilities in eastern North Carolina, and examines how electricity as a material technology interacted with geographies of race and class, as well as the dictates of capital accumulation. This approach enables a rethinking of several concepts that are rarely examined by scholars of electric utilities, most notably the monopoly service territory, which I argue served as a spatial fix to accumulation problems in the industry. Further, examining the way that electric utilities developed in North Carolina during the 20th century brings to the forefront the at times contradictory relationships among systems of electricity provision, Jim Crow segregation, the Progressive Era, and the New Deal. Such a focus highlights the important role that the control of electricity provision played in shaping racial inequalities that continue to persist in the region. With most urban areas were electrified in the 1930s, the research also traces the electricity distribution lines as they moved out of cities through rural electrification programs, a shift that highlights the state as a multi-scalar and variegated actor that both aided and impeded electrification efforts by various institutional and corporate entities. Ultimately, I argue that the historical geography of electricity is a critical factor that must be considered in order to adequately understand and address the issues of inequality and poverty that continue to persist in the region.

The principal effort under this program was directed at the fuel cell stack technology required to accomplish the initial feasibility demonstrations of increased cell stack operating pressures and temperatures, increased cell active area, incorporation of the ribbed substrate cell configuration at the bove conditions, and the introduction of higher performance electrocatalysts. The program results were successful with the primary accomplishments being: (1) fabrication of 10 sq ft ribbed substrate, cell components including higher performing electrocatalysts; (2) assembly of a 10 sq ft, 30-cell short stack; and (3) initial test of this stack at 120 psia and 405 F. These accomplishments demonstrate the feasibility of fabricating and handling large area cells using materials and processes that are oriented to low cost manufacture. An additional accomplishment under the program was the testing of two 3.7 sq ft short stacks at 12 psia/405 F to 5400 and 4500 hours respectively. These tests demonstrate the durability of the components and the cell stack configuration to a nominal 5000 hours at the higher pressure and temperature condition planned for the next electric utility power plant.

Accuracy analysis for DSM and orthoimages derived from SPOT HRS stereo data using direct georeferencing

NASA Astrophysics Data System (ADS)

Reinartz, Peter; Müller, Rupert; Lehner, Manfred; Schroeder, Manfred

During the HRS (High Resolution Stereo) Scientific Assessment Program the French space agency CNES delivered data sets from the HRS camera system with high precision ancillary data. Two test data sets from this program were evaluated: one is located in Germany, the other in Spain. The first goal was to derive orthoimages and digital surface models (DSM) from the along track stereo data by applying the rigorous model with direct georeferencing and without ground control points (GCPs). For the derivation of DSM, the stereo processing software, developed at DLR for the MOMS-2P three line stereo camera was used. As a first step, the interior and exterior orientation of the camera, delivered as ancillary data from positioning and attitude systems were extracted. A dense image matching, using nearly all pixels as kernel centers provided the parallaxes. The quality of the stereo tie points was controlled by forward and backward matching of the two stereo partners using the local least squares matching method. Forward intersection lead to points in object space which are subsequently interpolated to a DSM in a regular grid. DEM filtering methods were also applied and evaluations carried out differentiating between accuracies in forest and other areas. Additionally, orthoimages were generated from the images of the two stereo looking directions. The orthoimage and DSM accuracy was determined by using GCPs and available reference DEMs of superior accuracy (DEM derived from laser data and/or classical airborne photogrammetry). As expected the results obtained without using GCPs showed a bias in the order of 5-20 m to the reference data for all three coordinates. By image matching it could be shown that the two independently derived orthoimages exhibit a very constant shift behavior. In a second step few GCPs (3-4) were used to calculate boresight alignment angles, introduced into the direct georeferencing process of each image independently. This method improved the absolute accuracy of the resulting orthoimages and DSM significantly.

The purpose of this research was to expand knowledge in the current literature regarding treatment retention in intensive outpatient substance abuse treatment programs. The sample in this study participated in a hospital-based program accredited by the Joint Commission on Accreditation for Health Organizations (JCAHO) that utilized the Minnesota model. Specifically, this inquiry investigated whether treatment retention would be predicted by gender, age, employment status, number of problems on the treatment plan, whether the referral was related to driving while intoxicated (DWI), marital status, race, and whether each of the following substance problems was listed as the client's primary DSM-IV diagnosis: alcohol dependence, cocaine dependence, polysubstance dependence, opioid dependence, sedative/hypnotic dependence, cannabis dependence, other (or unknown) dependence, alcohol abuse, cannabis abuse, amphetamine abuse, and caffeine intoxication. Findings indicated that those retained in treatment, when compared to those who dropped out, had significantly more problems on their treatment plans, were more likely to be alcoholics, were less often cocaine addicts, and were more likely to be employed. The results of this study suggest that clients with this profile have increased likelihood of being retained in intensive outpatient substance abuse treatment programs.

Smart Grid Risk Management

NASA Astrophysics Data System (ADS)

Abad Lopez, Carlos Adrian

Current electricity infrastructure is being stressed from several directions -- high demand, unreliable supply, extreme weather conditions, accidents, among others. Infrastructure planners have, traditionally, focused on only the cost of the system; today, resilience and sustainability are increasingly becoming more important. In this dissertation, we develop computational tools for efficiently managing electricity resources to help create a more reliable and sustainable electrical grid. The tools we present in this work will help electric utilities coordinate demand to allow the smooth and large scale integration of renewable sources of energy into traditional grids, as well as provide infrastructure planners and operators in developing countries a framework for making informed planning and control decisions in the presence of uncertainty. Demand-side management is considered as the most viable solution for maintaining grid stability as generation from intermittent renewable sources increases. Demand-side management, particularly demand response (DR) programs that attempt to alter the energy consumption of customers either by using price-based incentives or up-front power interruption contracts, is more cost-effective and sustainable in addressing short-term supply-demand imbalances when compared with the alternative that involves increasing fossil fuel-based fast spinning reserves. An essential step in compensating participating customers and benchmarking the effectiveness of DR programs is to be able to independently detect the load reduction from observed meter data. Electric utilities implementing automated DR programs through direct load control switches are also interested in detecting the reduction in demand to efficiently pinpoint non-functioning devices to reduce maintenance costs. We develop sparse optimization methods for detecting a small change in the demand for electricity of a customer in response to a price change or signal from the utility, dynamic learning methods for scheduling the maintenance of direct load control switches whose operating state is not directly observable and can only be inferred from the metered electricity consumption, and machine learning methods for accurately forecasting the load of hundreds of thousands of residential, commercial and industrial customers. These algorithms have been implemented in the software system provided by AutoGrid, Inc., and this system has helped several utilities in the Pacific Northwest, Oklahoma, California and Texas, provide more reliable power to their customers at significantly reduced prices. Providing power to widely spread out communities in developing countries using the conventional power grid is not economically feasible. The most attractive alternative source of affordable energy for these communities is solar micro-grids. We discuss risk-aware robust methods to optimally size and operate solar micro-grids in the presence of uncertain demand and uncertain renewable generation. These algorithms help system operators to increase their revenue while making their systems more resilient to inclement weather conditions.

Sustainable Energy Solutions for Rural Alaska

Allen, Riley; Brutkoski, Donna; Farnsworth, David

2016-04-22

The state of Alaska recognizes the challenges these rural communities face and provides financial support via the Power Cost Equalization (PCE) program. The PCE subsidizes the electricity prices paid by customers of these high-cost utilities. The PCE program is designed to spread the benefits of Alaska’s natural resources more evenly throughout the state. Yet even with this subsidy, electricity is still much more expensive for these rural customers. And beyond the PCE, other forms of assistance to rural utilities are becoming scarce given the state’s current fiscal environment. Nearly 90 percent of Alaska’s unrestricted budget funds in recent years havemore » been tied to oil royalties—a sector experiencing significant declines in production and oil prices. Consequently, as Alaska looks to tighten budgets, the challenge of lowering rural utility costs, while encouraging self-sufficiency, has become more urgent.This study examines reliability, capital and strategic planning, management, workforce development, governance, financial performance and system efficiency in the various communities visited by the research team. Using those attributes, a tier system was developed to categorize rural Alaska utilities into Leading and Innovating Systems (Tier I), Advanced Diesel Systems (Tier II), Basic Systems (Tier III), and Underperforming Systems (Tier IV). The tier approach is not meant to label specific utilities, but rather to provide a general set of benchmarks and guideposts for improvement.« less

To review the evidence for the validity and utility of subtyping bulimia nervosa (BN) into a purging (BN-P) and a nonpurging subtype (BN-NP), and of distinguishing BN-NP from binge eating disorder (BED), by comparing course, complications, and treatment. A literature search of psychiatry databases for studies published in peer-reviewed journals that used the DSM-definitions of BN and BED, and included both individuals with BN-NP and individuals with BN-P and/or BED. Twenty-three studies compared individuals with BN-NP (N = 671) to individuals with BN-P (N = 1795) and/or individuals with BED (N = 1921), two of which reported on course, 12 on comorbidity and none on treatment response-the indicators for validity and clinical utility. The differences found were mainly quantitative rather than qualitative, suggesting a gradual difference in severity from BN-P (most severe) through BN-NP to BED (least severe). None of the comparisons provided convincing evidence for the validity or utility of the BN-NP diagnosis. Three options for the position of BN-NP in DSM-V were suggested: (1) maintaining the BN-NP subtype, (2) dropping nonpurging compensatory behavior as a criterion for BN, so that individuals currently designated as having BN-NP would be designated as having BED, and (3) including BN-NP in a broad BN category.

The estimated impact of California’s urban water conservation mandate on electricity consumption and greenhouse gas emissions

NASA Astrophysics Data System (ADS)

Spang, Edward S.; Holguin, Andrew J.; Loge, Frank J.

2018-01-01

In April 2015, the Governor of California mandated a 25% statewide reduction in water consumption (relative to 2013 levels) by urban water suppliers. The more than 400 public water agencies affected by the regulation were also required to report monthly progress towards the conservation goal to the State Water Resources Control Board. This paper uses the reported data to assess how the water utilities have responded to this mandate and to estimate the electricity savings and greenhouse gas (GHG) emissions reductions associated with reduced operation of urban water infrastructure systems. The results show that California succeeded in saving 524 000 million gallons (MG) of water (a 24.5% decrease relative to the 2013 baseline) over the mandate period, which translates into 1830 GWh total electricity savings, and a GHG emissions reduction of 521 000 metric tonnes of carbon dioxide equivalents (MT CO2e). For comparison, the total electricity savings linked to water conservation are approximately 11% greater than the savings achieved by the investor-owned electricity utilities’ efficiency programs for roughly the same time period, and the GHG savings represent the equivalent of taking about 111 000 cars off the road for a year. These indirect, large-scale electricity and GHG savings were achieved at costs that were competitive with existing programs that target electricity and GHG savings directly and independently. Finally, given the breadth of the results produced, we built a companion website, called ‘H2Open’ (https://cwee.shinyapps.io/greengov/), to this research effort that allows users to view and explore the data and results across scales, from individual water utilities to the statewide summary.

In the aftermath of PURPA: The future of the biomass energy industry in Maine

DOE Office of Scientific and Technical Information (OSTI.GOV)

Adams, S.J.; Connors, J.F.

During the 1980`s the biomass power industry in Maine grew to nearly 500 MW of installed capacity in 21 cogeneration and stand alone plants. By 1992 these plants consumed four million tons of woody fuels annually, while providing 25% of the states` electricity supply. Moreover, this new industry supported over 2500 jobs throughout rural Maine, generated substantial local property taxes and provided a critically need management option for forest management and mill waste disposal. All of this capacity was developed by non-utility generators as Qualifying Facilities (QF) under PURPA rules. Most power contracts were fixed price, must take agreements guidedmore » by avoided cost calculations that assumed high future costs for energy alternatives. Circumstances have changed. Historically low oil prices, economic recession, and rising electricity rates have made biomass fueled power plants some of the most expensive sources of electricity on the power grid. Utilities are responding to rising rates, to public and political pressure to control costs and lower rates by seeking to renegotiate or buy out power contracts and closing biomass plants. While there are strong demands to control electricity costs, there are equally strong concerns about losing the benefits that accrue from the use of indigenous renewable resources. This article evaluates the actions of Maine utilities, independent power producers, the Maine Public Utilities Commission, and the Main Legislature related to PURPA contracts and their likely effects on the future of the biomass power industry in Maine. In particular, we will describe Maine`s new Electric Rate Stabilization Program and subsequent efforts of the Executive Branch to mediate a compromise solution in one case of a utility buy out of a biomass power plant.« less

FUEL-FLEXIBLE GASIFICATION-COMBUSTION TECHNOLOGY FOR PRODUCTION OF H2 AND SEQUESTRATION-READY CO2

DOE Office of Scientific and Technical Information (OSTI.GOV)

George Rizeq; Janice West; Arnaldo Frydman

It is expected that in the 21st century the Nation will continue to rely on fossil fuels for electricity, transportation, and chemicals. It will be necessary to improve both the thermodynamic efficiency and environmental impact performance of fossil fuel utilization. General Electric Energy and Environmental Research Corporation (GE EER) has developed an innovative fuel-flexible Advanced Gasification-Combustion (AGC) concept to produce H{sub 2} and sequestration-ready CO{sub 2} from solid fuels. The AGC module offers potential for reduced cost and increased energy efficiency relative to conventional gasification and combustion systems. GE EER was awarded a Vision-21 program from U.S. DOE NETL tomore » develop the AGC technology. Work on this three-year program started on October 1, 2000. The project team includes GE EER, California Energy Commission, Southern Illinois University at Carbondale, and T. R. Miles, Technical Consultants, Inc. In the AGC technology, coal/opportunity fuels and air are simultaneously converted into separate streams of (1) pure hydrogen that can be utilized in fuel cells, (2) sequestration-ready CO{sub 2}, and (3) high temperature/pressure oxygen-depleted air to produce electricity in a gas turbine. The process produces near-zero emissions and, based on preliminary modeling work in the first quarter of this program, has an estimated process efficiency of approximately 67% based on electrical and H{sub 2} energy outputs relative to the higher heating value of coal. The three-year R&D program will determine the operating conditions that maximize separation of CO{sub 2} and pollutants from the vent gas, while simultaneously maximizing coal conversion efficiency and hydrogen production. The program integrates lab-, bench- and pilot-scale studies to demonstrate the AGC concept. This is the fifth quarterly technical progress report for the Vision-21 AGC program supported by U.S. DOE NETL (Contract: DE-FC26-00FT40974). This report summarizes program accomplishments for the period starting October 1, 2001 and ending December 31, 2001. The report includes an introduction summarizing the AGC concept, main program tasks, and program objectives; it also provides a summary of program activities covering program management and progress in tasks including lab- and bench-scale experimental testing, pilot-scale design, and economic studies.« less

The Outline for Cultural Formulation (OCF) introduced with DSM-IV provided a framework for clinicians to organize cultural information relevant to diagnostic assessment and treatment planning. However, use of the OCF has been inconsistent, raising questions about the need for guidance on implementation, training, and application in diverse settings. To address this need, DSM-5 introduced a cultural formulation interview (CFI) that operationalizes the process of data collection for the OCF. The CFI includes patient and informant versions and 12 supplementary modules addressing specific domains of the OCF. This article summarizes the literature reviews and analyses of experience with the OCF conducted by the DSM-5 Cross-Cultural Issues Subgroup (DCCIS) that informed the development of the CFI. We review the history and contents of the DSM-IV OCF, its use in training programs, and previous attempts to render it operational through questionnaires, protocols, and semi-structured interview formats. Results of research based on the OCF are discussed. For each domain of the OCF, we summarize findings from the DCCIS that led to content revision and operationalization in the CFI. The conclusion discusses training and implementation issues essential to service delivery. PMID:24865197

An analysis of the impact of Renewable Portfolio Standards on residential electricity prices

NASA Astrophysics Data System (ADS)

Larson, Andrew James

A Renewable Portfolio Standard (RPS) has become a popular policy for states seeking to increase the amount of renewable energy generated for consumers of electricity. The success of these state programs has prompted debate about the viability of a national RPS. The impact that these state level policies have had on the price consumers pay for electricity is the subject of some debate. Several federal organizations have conducted studies of the impact that a national RPS would have on electricity prices paid by consumers. NREL and US EIA utilize models that analyze the inputs in electricity generation to examine the future price impact of changes to electricity generation and show marginal increases in prices paid by end users. Other empirical research has produced similar results, showing that the existence of an RPS increases the price of electricity. These studies miss important aspects of RPS policies that may change how we view these price increases from RPS policies. By examining the previous empirical research on RPS policies, this study seeks to identify the controls necessary to build an effective model. These controls are utilized in a fixed effects model that seeks to show how the controls and variables of interest impact electricity prices paid by residential consumers of electricity. This study utilizes a panel data set from 1990 to 2014 to analyze the impact of these policies controlling for generating capacity, the regulatory status of utilities in each state, demographic characteristics of the states, and fuel prices. The results of the regressions indicate that prices are likely to be higher in states that have an RPS compared to states that do not have such a policy. Several of the characteristics mentioned above have price impacts, and so discussing RPS policies in the context of other factors that contribute to electricity prices is essential. In particular, the regulatory status of utilities in each state is an important determinate of price as well as the amount of renewable energy generated in each state. There are several implications of this analysis that are relevant for policy makers who seek to gain the environmental benefits of these policies, but who are also concerned with the costs those polices may impose on consumers of electricity. First, allowing utilities as much time as possible to comply with the mandates of the RPS will mitigate the price increases associated with implementation of and compliance with the policy. Secondly, policy makers need not fear imposing high targets for their RPS as this is not associated with higher electricity prices. Finally, policy makers should be concerned with the bindingness of the policies they impose. States with non-binding policies tend to have higher electricity prices, likely due to the costs of early compliance. As such imposing interim targets may raise rates more than simply allowing compliance at a pace utilities can bear without substantially increasing prices.

This article describes the implementation and utilization of the patient and family education program (PFEP) component of the Texas Medication Algorithm Project (TMAP). The extent of participation, types of psychoeducation received, and predictors of receiving at least a minimum level of education are presented. TMAP included medication guidelines, a dedicated clinical coordinator, standardized assessments of symptoms and side effects, uniform documentation, and a PFEP. The PFEP includes phased, multimodal, disorder-specific educational materials for patients and families. Participants were adult outpatients of 1 of 7 community mental health centers in Texas that were implementing the TMAP disease management package. Patients had DSM-IV clinical diagnoses of major depressive disorder, with or without psychotic features; bipolar I disorder or schizoaffective disorder, bipolar type; or schizophrenia or schizoaffective disorder. Assessments were administered by independent research coordinators. Study data were collected between March 1998 and March 2000, and patients participated for at least 1 year. Of the 487 participants, nearly all (95.1%) had at least 1 educational encounter, but only 53.6% of participants met criteria for "minimum exposure" to individual education interventions. Furthermore, only 31.0% participated in group education, and 42.5% had a family member involved in at least 1 encounter. Participants with schizophrenia were less involved in the PFEP across multiple indicators of utilization. Diagnosis, intensity of symptoms, age, and receipt of public assistance were related to the likelihood of exposure to minimum levels of individual education. Despite adequate resources and infrastructure to provide PFEP, utilization was less than anticipated. Although implementation guidelines were uniform across diagnoses, participants with schizophrenia experienced less exposure to psychoeducation. Recommendations for improving program implementation and modification of materials are discussed.

Cross-cultural mental health researchers often analyze patient explanatory models of illness to optimize service provision. The Cultural Formulation Interview (CFI) is a cross-cultural assessment tool released in May 2013 with DSM-5 to revise shortcomings from the DSM-IV Outline for Cultural Formulation (OCF). The CFI field trial took place in 6 countries, 14 sites, and with 321 patients to explore its feasibility, acceptability, and clinical utility with patients and clinicians. We sought to analyze if and how CFI feasibility, acceptability, and clinical utility were related to patient-clinician communication. We report data from the New York site which enrolled 7 clinicians and 32 patients in 32 patient-clinician dyads. We undertook a data analysis independent of the parent field trial by conducting content analyses of debriefing interviews with all participants (n = 64) based on codebooks derived from frameworks for medical communication and implementation outcomes. Three coders created codebooks, coded independently, established inter-rater coding reliability, and analyzed if the CFI affects medical communication with respect to feasibility, acceptability, and clinical utility. Despite racial, ethnical, cultural, and professional differences within our group of patients and clinicians, we found that promoting satisfaction through the interview, eliciting data, eliciting the patient's perspective, and perceiving data at multiple levels were common codes that explained how the CFI affected medical communication. We also found that all but two codes fell under the implementation outcome of clinical utility, two fell under acceptability, and none fell under feasibility. Our study offers new directions for research on how a cultural interview affects patient-clinician communication. Future research can analyze how the CFI and other cultural interviews impact medical communication in clinical settings with subsequent effects on outcomes such as medication adherence, appointment retention, and health condition.

The Social Cognition and Object Relations Scale (SCORS), developed by Western, Lohr, Silk, Kerber, and Goodrich (1985), is a diagnostic instrument used to assess an array of psychological functioning by using clinical narratives such as the Thematic Apperception Test (TAT; Murray, 1943) stories. This study investigated the utility of the SCORS to differentiate between Diagnostic and Statistical Manual of Mental Disorders (4th ed. [DSM-IV]; American Psychiatric Association, 1994) antisocial personality disorder (ANPD), borderline personality disorder (BPD), narcissistic personality disorder (NPD), and Cluster C personality disorder (CPD). A sample of 58 patients was separated into four groups: ANPD (n = 9), BPD (n = 21; 18 with a primary BPD diagnosis and 3 with prominent borderline traits who met 4 of the 5 DSM-IV criteria necessary for a BPD diagnosis), NPD (n = 16; 8 with a primary NPD diagnosis and 8 with prominent narcissistic traits who met 4 of the 5 DSM-IV criteria necessary for a NPD diagnosis), and CPD (n = 12). These groups were then compared on the 8 SCORS variables by using 5 TAT cards (1, 2, 3BM, 4, and 13MF). Spearman-Brown correction for 2-way mixed effects model of reliability for the 8 SCORS variables ranged from .70 to .95. The results of categorical and dimensional analyses indicate that (a) SCORS variables can be used to differentiate ANPD, BPD, and NPD; (b) the BPD group scored significantly lower (greater maladjustment) than did the CPD group on certain variables; (c) the BPD group scored significantly lower (greater maladjustment) than did the NPD group on all 8 SCORS variables; (d) the ANPD group scored significantly lower than did the NPD group on certain variables; (e) certain variables were found to be empirically related to the total number of DSM-IV ANPD, BPD, and NPD criteria; and (f) certain variables were found to be empirically related to Minnesota Multiphasic Personality Inventory-2 (MMPI-2; Butcher, Dahlstrom, Graham, Tellegen, & Kaemmer, 1989) Personality disorder scales. The results of this study are discussed in terms of clinical utility, conceptual, and theoretical implications.

Background Preschool-onset depression, a developmentally adapted form of depression arising between the ages of 3–6, has demonstrated numerous features of validity including characteristic alterations in stress reactivity and brain function. Notably, this validated syndrome with multiple clinical markers is characterized by sub-threshold DSM Major Depressive Disorder criteria, raising questions about its clinical significance. To clarify the utility and public health significance of the preschool-onset depression construct, diagnostic outcomes of this group at school age and adolescence were investigated. Methods We investigated the likelihood of meeting full DSM Major Depressive Disorder criteria in later childhood (i.e., ≥ age 6) as a function of preschool depression, other preschool Axis I disorders, maternal depression, parenting non-support and traumatic life events in a longitudinal prospective study of preschool children. Results Preschool-onset depression emerged as a robust predictor of DSM-5 Major Depressive Disorder in later childhood even after accounting for the effect of maternal depression and other risk factors. Preschool-onset conduct disorder also predicted DSM-5 Major Depressive Disorder in later childhood, but this association was partially mediated by maternal non-support, reducing the effect of preschool conduct disorder in predicting DSM depression by 21%. Discussion Study findings provide evidence that this preschool depressive syndrome is a robust risk factor for meeting full DSM criteria for Major Depressive Disorder in later childhood over and above other established risk factors. Preschool conduct disorder also predicted Major Depressive Disorder but was mediated by maternal non-support. Findings suggest that attention to preschool depression and conduct disorder in addition to maternal depression and exposure to trauma should now become an important factor for identification of young children at highest risk for later MDD who should be targeted for early interventions.

Our goal is to create an ontology that will allow data integration and reasoning with subject data to classify subjects, and based on this classification, to infer new knowledge on Autism Spectrum Disorder (ASD) and related neurodevelopmental disorders (NDD). We take a first step toward this goal by extending an existing autism ontology to allow automatic inference of ASD phenotypes and Diagnostic & Statistical Manual of Mental Disorders (DSM) criteria based on subjects' Autism Diagnostic Interview-Revised (ADI-R) assessment data. Knowledge regarding diagnostic instruments, ASD phenotypes and risk factors was added to augment an existing autism ontology via Ontology Web Language class definitions and semantic web rules. We developed a custom Protégé plugin for enumerating combinatorial OWL axioms to support the many-to-many relations of ADI-R items to diagnostic categories in the DSM. We utilized a reasoner to infer whether 2642 subjects, whose data was obtained from the Simons Foundation Autism Research Initiative, meet DSM-IV-TR (DSM-IV) and DSM-5 diagnostic criteria based on their ADI-R data. We extended the ontology by adding 443 classes and 632 rules that represent phenotypes, along with their synonyms, environmental risk factors, and frequency of comorbidities. Applying the rules on the data set showed that the method produced accurate results: the true positive and true negative rates for inferring autistic disorder diagnosis according to DSM-IV criteria were 1 and 0.065, respectively; the true positive rate for inferring ASD based on DSM-5 criteria was 0.94. The ontology allows automatic inference of subjects' disease phenotypes and diagnosis with high accuracy. The ontology may benefit future studies by serving as a knowledge base for ASD. In addition, by adding knowledge of related NDDs, commonalities and differences in manifestations and risk factors could be automatically inferred, contributing to the understanding of ASD pathophysiology.

To test both the concurrent and predictive significance of the new DSM-5 severity specifier for binge-eating disorder (BED) in adult outpatients. Existing data from 195 adults with DSM-5 BED who received evidence-based treatment (manual-based cognitive-behavioral therapy) in an outpatient setting were re-analysed to examine whether these patients sub-grouped according to the DSM-5 severity levels, defined by the frequency of binge-eating (BE) episodes, would show meaningful differences in a range of variables of clinical interest assessed at pre-treatment and end-of treatment abstinence from BE. Participants categorized with mild (33.3% of the sample), moderate (35.4%), severe (15.9%), and extreme (15.4%) severity of BED, based on their pre-treatment clinician-rated frequency of BE episodes, differed significantly from each other in physical characteristics (body mass index) and another sixteen variables of clinical interest assessed at pre-treatment regarding eating disorder psychopathology and putative maintenance factors, lifetime and current psychiatric disorder comorbidity, general psychiatric distress, and psychosocial impairment. The four DSM-5 severity groups were statistically indistinguishable in demographics or age-of-BED onset. However, significant between-group differences were observed in the treatment outcome, i.e., abstinence from BE, achieved by 98.5%, 66.7%, 38.7% and 6.7% of participants categorized with mild, moderate, severe, and extreme severity respectively. The outcome analyses repeated in the completer sample (n = 187) yielded the same pattern of the aforementioned intent-to-treat (N = 195) results. The findings provide support for the severity specifier for BED introduced in the DSM-5 as a means of addressing within-group variability in severity. © 2017 Wiley Periodicals, Inc.

Concurrent and prognostic utility of subtyping anorexia nervosa along dietary and negative affect dimensions.

Bulimia nervosa can be reliably classified into subtypes based on dimensions of dietary restraint and negative affect. Community and clinical studies have shown that dietary-negative affect subtypes have greater test-retest reliability and concurrent and predictive validity compared to subtypes based on the Diagnostic and Statistical Manual of Mental Disorders (DSM). Although dietary-negative affect subtypes have shown utility for characterizing eating disorders that involve binge eating, this framework may have broader implications for understanding restrictive eating disorders. The purpose of this study was to test the concurrent and predictive validity of dietary-negative affect subtypes among patients with anorexia nervosa (AN; N = 194). Latent profile analysis was used to identify subtypes of AN based on dimensions of dietary restraint and negative affect. Chi-square and multivariate analysis of variance were used to characterize baseline differences between identified subtypes. Structural equation modeling was used to test whether dietary-negative affect subtypes would outperform DSM categories in predicting clinically relevant outcomes. Results supported a 2-profile model that replicated dietary-negative affect subtypes: Latent Profile 1 (n = 68) had clinically elevated scores on restraint only; Latent Profile 2 (n = 126) had elevated scores on both restraint and negative affect. Validation analyses showed that membership in the dietary-negative affect profile was associated with greater lifetime psychiatric comorbidity and psychosocial impairment compared to the dietary class. Dietary-negative affect subtypes only outperformed DSM categories in predicting quality-of-life impairment at 1-year follow-up. Findings highlight the clinical utility of subtyping AN based on dietary restraint and negative affect for informing future treatment-matching or personalized medicine strategies.

This report describes Phase III of a project entitled Innovative Applications of Energy Storage in a Restructured Electricity Marketplace. For this study, the authors assumed that it is feasible to operate an energy storage plant simultaneously for two primary applications: (1) energy arbitrage, i.e., buy-low-sell-high, and (2) to reduce peak loads in utility ''hot spots'' such that the utility can defer their need to upgrade transmission and distribution (T&D) equipment. The benefits from the arbitrage plus T&D deferral applications were estimated for five cases based on the specific requirements of two large utilities operating in the Eastern U.S. A numbermore » of parameters were estimated for the storage plant ratings required to serve the combined application: power output (capacity) and energy discharge duration (energy storage). In addition to estimating the various financial expenditures and the value of electricity that could be realized in the marketplace, technical characteristics required for grid-connected distributed energy storage used for capacity deferral were also explored.« less

Opportunities for Decarbonizing Existing U.S. Coal-Fired Power Plants via CO2 Capture, Utilization and Storage.

2015-07-07

This study employs a power plant modeling tool to explore the feasibility of reducing unit-level emission rates of CO2 by 30% by retrofitting carbon capture, utilization, and storage (CCUS) to existing U.S. coal-fired electric generating units (EGUs). Our goal is to identify feasible EGUs and their key attributes. The results indicate that for about 60 gigawatts of the existing coal-fired capacity, the implementation of partial CO2 capture appears feasible, though its cost is highly dependent on the unit characteristics and fuel prices. Auxiliary gas-fired boilers can be employed to power a carbon capture process without significant increases in the cost of electricity generation. A complementary CO2 emission trading program can provide additional economic incentives for the deployment of CCS with 90% CO2 capture. Selling and utilizing the captured CO2 product for enhanced oil recovery can further accelerate CCUS deployment and also help reinforce a CO2 emission trading market. These efforts would allow existing coal-fired EGUs to continue to provide a significant share of the U.S. electricity demand.

Near-term hybrid vehicle program, phase 1. Appendix B: Design trade-off studies. [various hybrid/electric power train configurations and electrical and mechanical drive-line components

NASA Technical Reports Server (NTRS)

1979-01-01

The relative attractiveness of various hybrid/electric power train configurations and electrical and mechanical drive-line components was studied. The initial screening was concerned primarily with total vehicle weight and economic factors and identified the hybrid power train combinations which warranted detailed evaluation over various driving cycles. This was done using a second-by-second vehicle simulation program which permitted the calculations of fuel economy, electricity usage, and emissions as a function of distance traveled in urban and highway driving. Power train arrangement possibilities were examined in terms of their effect on vehicle handling, safety, serviceability, and passenger comfort. A dc electric drive system utilizing a separately excited motor with field control and battery switching was selected for the near term hybrid vehicle. Hybrid vehicle simulations showed that for the first 30 mi (the electric range of the vehicle) in urban driving, the fuel economy was 80 mpg using a gasoline engine and 100 mpg using a diesel engine. In urban driving the hybrid would save about 75% of the fuel used by the conventional vehicle and in combined urban/highway driving the fuel saving is about 50%.

It is expected that in the 21st century the Nation will continue to rely on fossil fuels for electricity, transportation, and chemicals. It will be necessary to improve both the process efficiency and environmental impact performance of fossil fuel utilization. GE Energy and Environmental Research Corporation (GE EER) has developed an innovative fuel-flexible Unmixed Fuel Processor (UFP) technology to produce H{sub 2}, power, and sequestration-ready CO{sub 2} from coal and other solid fuels. The UFP module offers the potential for reduced cost, increased process efficiency relative to conventional gasification and combustion systems, and near-zero pollutant emissions including NO{sub x}. GEmore » EER (prime contractor) was awarded a Vision 21 program from U.S. DOE NETL to develop the UFP technology. Work on this Phase I program started on October 1, 2000. The project team includes GE EER, Southern Illinois University at Carbondale (SIU-C), California Energy Commission (CEC), and T. R. Miles, Technical Consultants, Inc. In the UFP technology, coal/opportunity fuels and air are simultaneously converted into separate streams of (1) pure hydrogen that can be utilized in fuel cells, (2) sequestration-ready CO{sub 2}, and (3) high temperature/pressure oxygen-depleted air to produce electricity in a gas turbine. The process produces near-zero emissions and, based on process modeling work, has an estimated process efficiency of 68%, based on electrical and H{sub 2} energy outputs relative to the higher heating value of coal, and an estimated equivalent electrical efficiency of 60%. The Phase I R&D program will determine the operating conditions that maximize separation of CO{sub 2} and pollutants from the vent gas, while simultaneously maximizing coal conversion efficiency and hydrogen production. The program integrates lab-, bench- and pilot-scale studies to demonstrate the UFP technology.

Utility of the Personality Inventory for DSM-5-Brief Form (PID-5-BF) in the Measurement of Maladaptive Personality and Psychopathology.

2018-07-01

The Diagnostic and Statistical Manual of Mental Disorders-Fifth edition ( DSM-5) Personality and Personality Disorders workgroup developed the Personality Inventory for the DSM-5 (PID-5) for the assessment of the alternative trait model for DSM-5. Along with this measure, the American Psychiatric Association published an abbreviated version, the PID-5-Brief form (PID-5-BF). Although this measure is available on the DSM-5 website for use, only two studies have evaluated its psychometric properties and validity and no studies have examined the U.S. version of this measure. The current study evaluated the reliability, factor structure, and construct validity of PID-5-BF scale scores. This included an evaluation of the scales' associations with Section II PDs, a well-validated dimensional measure of personality psychopathology, and broad externalizing and internalizing psychopathology measures. We found support for the reliability of PID-5-BF scales as well as for the factor structure of the measure. Furthermore, a series of correlation and regression analyses showed conceptually expected associations between PID-5-BF and external criterion variables. Finally, we compared the correlations with external criterion measures to those of the full-length PID-5 and PID-5-Short form. Intraclass correlation analyses revealed a comparable pattern of correlations across all three measures, thereby supporting the use of the PID-5-BF as a screening measure of dimensional maladaptive personality traits.

Initial interpretation and evaluation of a profile-based classification system for the anxiety and mood disorders: Incremental validity compared to DSM-IV categories.

Limitations in anxiety and mood disorder diagnostic reliability and validity due to the categorical approach to classification used by the Diagnostic and Statistical Manual of Mental Disorders (DSM) have been long recognized. Although these limitations have led researchers to forward alternative classification schemes, few have been empirically evaluated. In a sample of 1,218 outpatients with anxiety and mood disorders, the present study examined the validity of Brown and Barlow's (2009) proposal to classify the anxiety and mood disorders using an integrated dimensional-categorical approach based on transdiagnostic emotional disorder vulnerabilities and phenotypes. Latent class analyses of 7 transdiagnostic dimensional indicators suggested that a 6-class (i.e., profile) solution provided the best model fit and was the most conceptually interpretable. Interpretation of the classes was further supported when compared with DSM diagnoses (i.e., within-class prevalence of diagnoses, using diagnoses to predict class membership). In addition, hierarchical multiple regression models were used to demonstrate the incremental validity of the profiles; class probabilities consistently accounted for unique variance in anxiety and mood disorder outcomes above and beyond DSM diagnoses. These results provide support for the potential development and utility of a hybrid dimensional-categorical profile approach to anxiety and mood disorder classification. In particular, the availability of dimensional indicators and corresponding profiles may serve as a useful complement to DSM diagnoses for both researchers and clinicians.

Neurocognitive disorders: cluster 1 of the proposed meta-structure for DSM-V and ICD-11.

PubMed

Sachdev, P; Andrews, G; Hobbs, M J; Sunderland, M; Anderson, T M

2009-12-01

In an effort to group mental disorders on the basis of aetiology, five clusters have been proposed. In this paper, we consider the validity of the first cluster, neurocognitive disorders, within this proposal. These disorders are categorized as 'Dementia, Delirium, and Amnestic and Other Cognitive Disorders' in DSM-IV and 'Organic, including Symptomatic Mental Disorders' in ICD-10. We reviewed the literature in relation to 11 validating criteria proposed by a Study Group of the DSM-V Task Force as applied to the cluster of neurocognitive disorders. 'Neurocognitive' replaces the previous terms 'cognitive' and 'organic' used in DSM-IV and ICD-10 respectively as the descriptor for disorders in this cluster. Although cognitive/organic problems are present in other disorders, this cluster distinguishes itself by the demonstrable neural substrate abnormalities and the salience of cognitive symptoms and deficits. Shared biomarkers, co-morbidity and course offer less persuasive evidence for a valid cluster of neurocognitive disorders. The occurrence of these disorders subsequent to normal brain development sets this cluster apart from neurodevelopmental disorders. The aetiology of the disorders is varied, but the neurobiological underpinnings are better understood than for mental disorders in any other cluster. Neurocognitive disorders meet some of the salient criteria proposed by the Study Group of the DSM-V Task Force to suggest a classification cluster. Further developments in the aetiopathogenesis of these disorders will enhance the clinical utility of this cluster.

2010-02-01

This review evaluates the DSM-IV criteria of social anxiety disorder (SAD), with a focus on the generalized specifier and alternative specifiers, the considerable overlap between the DSM-IV diagnostic criteria for SAD and avoidant personality disorder, and developmental issues. A literature review was conducted, using the validators provided by the DSM-V Spectrum Study Group. This review presents a number of options and preliminary recommendations to be considered for DSM-V. Little supporting evidence was found for the current specifier, generalized SAD. Rather, the symptoms of individuals with SAD appear to fall along a continuum of severity based on the number of fears. Available evidence suggested the utility of a specifier indicating a "predominantly performance" variety of SAD. A specifier based on "fear of showing anxiety symptoms" (e.g., blushing) was considered. However, a tendency to show anxiety symptoms is a core fear in SAD, similar to acting or appearing in a certain way. More research is needed before considering subtyping SAD based on core fears. SAD was found to be a valid diagnosis in children and adolescents. Selective mutism could be considered in part as a young child's avoidance response to social fears. Pervasive test anxiety may belong not only to SAD, but also to generalized anxiety disorder. The data are equivocal regarding whether to consider avoidant personality disorder simply a severe form of SAD. Secondary data analyses, field trials, and validity tests are needed to investigate the recommendations and options.

Butanol production from thin stillage using Clostridium pasteurianum.

PubMed

Ahn, Jae-Hyung; Sang, Byoung-In; Um, Youngsoon

2011-04-01

The production of butanol from thin stillage by Clostridium pasteurianum DSM 525 was evaluated in the paper. At initial pH values ranging from 5.0 to 7.0 C. pasteurianum DSM 525 produced 6.2-7.2 g/L of butanol utilizing glycerol in thin stillage as the main carbon source, with yields of 0.32-0.44 g butanol produced/g glycerol consumed, which are higher than previously reported yields (e.g., 0.14-0.31 g butanol/g glycerol, Biebl, 2001). Lactic acid in the thin stillage acted as a buffering agent, maintaining the pH of the medium within a range of 5.7-6.1. Lactic acid was also utilized along with glycerol, enhancing butanol production (6.5 g/L butanol vs. 8.7 g/L butanol with 0 and 16 g/L lactic acid, respectively). These results demonstrate the feasibility of cost-effective butanol production using thin stillage as a nutrient-containing medium with a pH buffering capacity. Copyright © 2011 Elsevier Ltd.

Dunbar, W. G.

1981-01-01

Studies by NASA have shown that many of the space missions proposed for the time period 1980 to 2000 will require large spacecraft structures to be assembled in orbit. Large antennas and power systems up to 2.5 MW size are predicted to supply the electrical/electronic subsystems, solar electric subsystems, solar electric propulsion, and space processing for the near-term programs. Platforms of 100 meters/length for stable foundations, utility stations, and supports for these multi-antenna and electronic powered mechanisms are also being considered. This paper includes the findings of an analytic and conceptual design study for large spacecraft power distribution, and electrical loads and their influence on the cable and connector requirements for these proposed large spacecraft.

Teacher ratings of DSM-III-R symptoms for the disruptive behavior disorders.

PubMed

Pelham, W E; Gnagy, E M; Greenslade, K E; Milich, R

1992-03-01

Ratings were collected on a rating scale comprised of the DSM-III-R diagnostic criteria for disruptive behavior disorders. Teacher ratings were obtained for 931 boys in regular classrooms in grades K through 8 from around North America. Means and standard deviations for attention-deficit hyperactivity disorder (ADHD), oppositional-defiant disorder (ODD), and conduct disorder (CD) scales are reported by age. Frequencies of DSM-III-R symptoms are reported by age, and suggested diagnostic cutoffs are discussed. A factor analysis revealed three factors: one reflecting ODD and several CD symptoms, one on which ADHD symptoms of inattention loaded, and one comprised of ADHD impulsivity/overactivity symptoms. Conditional probability analyses revealed that several hallmark symptoms of ADHD had very poor predictive power, whereas combinations of symptoms from the two ADHD factors had good predictive power. Combinations of ODD symptoms also had very high predictive power. The limited utility of teacher ratings in assessing symptoms of conduct disorder in this age range is discussed.

Seaweed represents an abundant, renewable, and fast-growing biomass resource for 3rd generation biofuel production. This study reports an efficient butanol fermentation process carried out by Clostridium beijerinckii DSM-6422 using enzymatic hydrolysate of the sugar-rich brown seaweed Laminaria digitata harvested from the coast of the Danish North Sea as substrate. The highest butanol yield (0.42g/g-consumed-substrates) compared to literature was achieved, with a significantly higher butanol:acetone-butanol-ethanol (ABE) molar ratio (0.85) than typical (0.6). This demonstrates the possibility of using the seaweed L. digitata as a potential biomass for butanol production. For the first time, consumption of alginate components was observed by C. beijerinckii DSM-6422. The efficient utilization of sugars and lactic acid further highlighted the potential of using this strain for future development of large-scale cost-effective butanol production based on (ensiled) seaweed.

Lonigan, C J; Anthony, J L; Shannon, M P

1998-10-01

Examined 5 conditional probability indices to determine the diagnostic efficacy of 48 symptoms associated with posttraumatic stress disorder (PTSD) in 5,687 children exposed to Hurricane Hugo, of whom 5.5% had a diagnosis of posttraumatic stress syndrome (PTSS). Moderate levels of sensitivity and high levels of specificity were obtained for most symptoms. Odds ratios more precisely demonstrated that some Diagnostic and Statistical Manual of Mental Disorders (DSM) symptoms of PTSD, especially when combined, were useful for identifying children with PTSS but that anxiety symptoms and some DSM symptoms of PTSD had poor diagnostic utility. Satisfying criteria for the DSM-III-R numbing/avoidance cluster and symptoms from the numbing/avoidance cluster had the highest diagnostic efficacy, suggesting that avoidance may be the hallmark of severe posttraumatic reactions. These results suggest which symptoms should be conceptualized as central versus peripheral to the disorder and which symptoms and symptom combinations clinicians should attend to most when diagnosing or screening PTSD in children.

A Comparison of Obsessive-Compulsive Personality Disorder Scales

PubMed Central

Samuel, Douglas B.; Widiger, Thomas A.

2010-01-01

The current study utilized a large undergraduate sample (n = 536), oversampled for DSM-IV-TR obsessive-compulsive personality disorder (OCPD) pathology, to compare eight self-report measures of OCPD. No prior study has compared more than three measures and the results indicated that the scales had only moderate convergent validity. We also went beyond the existing literature to compare these scales to two external reference points: Their relationships with a well established measure of the five-factor model of personality (FFM) and clinicians' ratings of their coverage of the DSM-IV-TR criterion set. When the FFM was used as a point of comparison the results suggested important differences among the measures with respect to their divergent representation of conscientiousness, neuroticism, and agreeableness. Additionally, an analysis of the construct coverage indicated that the measures also varied in terms of their representation of particular diagnostic criteria. For example, while some scales contained items distributed across the diagnostic criteria, others were concentrated more heavily on particular features of the DSM-IV-TR disorder. PMID:20408023

This study examines the psychometric properties of the Vanderbilt AD/HD Diagnostic Teacher Rating Scale (VADTRS) and provides preliminary normative data from a large, geographically defined population. The VADTRS consists of the complete list of DSM-IV AD/HD symptoms, a screen for other disruptive behavior disorders, anxiety and depression, and ratings of academic and classroom behavior performance. Teachers in one suburban county completed the scale for their students during 2 consecutive years. Statistical methods included (a) exploratory and confirmatory latent variable analyses of item data, (b) evaluation of the internal consistency of the latent dimensions, (c) evaluation of latent structure concordance between school year samples, and (d) preliminary evaluation of criterion-related validity. The instrument comprises four behavioral dimensions and two performance dimensions. The behavioral dimensions were concordant between school years and were consistent with a priori DSM-IV diagnostic criteria. Correlations between latent dimensions and relevant, known disorders or problems varied from .25 to .66.

Optimal Multi-scale Demand-side Management for Continuous Power-Intensive Processes

NASA Astrophysics Data System (ADS)

Mitra, Sumit

With the advent of deregulation in electricity markets and an increasing share of intermittent power generation sources, the profitability of industrial consumers that operate power-intensive processes has become directly linked to the variability in energy prices. Thus, for industrial consumers that are able to adjust to the fluctuations, time-sensitive electricity prices (as part of so-called Demand-Side Management (DSM) in the smart grid) offer potential economical incentives. In this thesis, we introduce optimization models and decomposition strategies for the multi-scale Demand-Side Management of continuous power-intensive processes. On an operational level, we derive a mode formulation for scheduling under time-sensitive electricity prices. The formulation is applied to air separation plants and cement plants to minimize the operating cost. We also describe how a mode formulation can be used for industrial combined heat and power plants that are co-located at integrated chemical sites to increase operating profit by adjusting their steam and electricity production according to their inherent flexibility. Furthermore, a robust optimization formulation is developed to address the uncertainty in electricity prices by accounting for correlations and multiple ranges in the realization of the random variables. On a strategic level, we introduce a multi-scale model that provides an understanding of the value of flexibility of the current plant configuration and the value of additional flexibility in terms of retrofits for Demand-Side Management under product demand uncertainty. The integration of multiple time scales leads to large-scale two-stage stochastic programming problems, for which we need to apply decomposition strategies in order to obtain a good solution within a reasonable amount of time. Hence, we describe two decomposition schemes that can be applied to solve two-stage stochastic programming problems: First, a hybrid bi-level decomposition scheme with novel Lagrangean-type and subset-type cuts to strengthen the relaxation. Second, an enhanced cross-decomposition scheme that integrates Benders decomposition and Lagrangean decomposition on a scenario basis. To demonstrate the effectiveness of our developed methodology, we provide several industrial case studies throughout the thesis.

The role of thermal energy storage in industrial energy conservation

Duscha, R. A.; Masica, W. J.

1979-01-01

Thermal Energy Storage for Industrial Applications is a major thrust of the Department of Energy's Thermal Energy Storage Program. Utilizing Thermal Energy Storage (TES) with process or reject heat recovery systems is shown to be extremely beneficial for several applications. Recent system studies resulting from contracts awarded by the Department of Energy (DOE) identified four especially significant industries where TES appears attractive - food processing, paper and pulp, iron and steel, and cement. Potential annual fuel savings with large scale implementation of near term TES systems for these industries is over 9,000,000 bbl of oil. This savings is due to recuperation and storage in the food processing industry, direct fuel substitution in the paper and pulp industry and reduction in electric utility peak fuel use through inplant production of electricity from utilization of reject heat in the steel and cement industries.

2017-07-01

An alternative model for personality disorders is included in Section III (Emerging Models and Measures) of Diagnostic and Statistical Manual of Mental Disorders, (5th ed.; DSM-5). The DSM-5 dimensional trait model is an extension of the Five-Factor Model (FFM; American Psychiatric Association, 2013). The Personality Inventory for DSM-5 (PID-5) assesses the 5 domains and 25 traits in the alternative model. The current study expands on recent research to examine the relationship of the PID-5 with an interview measure of the FFM. The Structured Interview for the Five Factor Model of Personality (SIFFM) assesses the 5 bipolar domains and 30 facets of the FFM. Research has indicated that the SIFFM captures maladaptive aspects of personality (as well as adaptive). The SIFFM, NEO PI-R, and PID-5 were administered to participants to examine their respective convergent and discriminant validity. Results provide evidence for the convergence of the 2 models using self-report and interview measures of the FFM. Clinical implications and future directions are discussed, particularly a call for the development of a structured interview for the assessment of the DSM-5 dimensional trait model.

A Psychometric Review of the Personality Inventory for DSM-5 (PID-5): Current Status and Future Directions.

2016-01-01

The paradigm of personality psychopathology is shifting from one that is purely categorical in nature to one grounded in dimensional individual differences. Section III (Emerging Measures and Models) of the Diagnostic and Statistical Manual of Mental Disorders (5th ed. [DSM-5]; American Psychiatric Association, 2013), for example, includes a hybrid categorical/dimensional model of personality disorder classification. To inform the hybrid model, the DSM-5 Personality and Personality Disorders Work Group developed a self-report instrument to assess pathological personality traits-the Personality Inventory for the DSM-5 (PID-5). Since its recent introduction, 30 papers (39 samples) have been published examining various aspects of its psychometric properties. In this article, we review the psychometric characteristics of the PID-5 using the Standards for Educational and Psychological Testing as our framework. The PID-5 demonstrates adequate psychometric properties, including a replicable factor structure, convergence with existing personality instruments, and expected associations with broadly conceptualized clinical constructs. More research is needed with specific consideration to clinical utility, additional forms of reliability and validity, relations with psychopathological personality traits using clinical samples, alternative methods of criterion validation, effective employment of cut scores, and the inclusion of validity scales to propel this movement forward.

To examine the longitudinal diagnostic efficiency of the DSM-IV criteria for obsessive-compulsive personality disorder (OCPD). At baseline, criteria and diagnoses were determined using diagnostic interviews, and blinded assessments were performed 24 months later with 550 participants. Diagnostic efficiency indices (conditional probabilities, total predictive power, and kappa) were calculated for each criterion determined at baseline, using the independent OCPD diagnosis at follow-up as the standard. Longitudinal diagnostic efficiencies for the OCPD criteria varied; findings suggested the overall predictive utility of 'preoccupied with details', 'rigid and stubborn', and 'reluctant to delegate'. These findings suggest the predictive validity of three cognitive-interpersonal OCPD criteria.

Physiological ecology of Clostridium glycolicum RD-1, an aerotolerant acetogen isolated from sea grass roots.

An anaerobic, H(2)-utilizing bacterium, strain RD-1, was isolated from the highest growth-positive dilution series of a root homogenate prepared from the sea grass Halodule wrightii. Cells of RD-1 were gram-positive, spore-forming, motile rods that were linked by connecting filaments. Acetate was produced in stoichiometries indicative of an acetyl coenzyme A (acetyl-CoA) pathway-dependent metabolism when RD-1 utilized H(2)-CO(2), formate, lactate, or pyruvate. Growth on sugars or ethylene glycol yielded acetate and ethanol as end products. RD-1 grew at the expense of glucose in the presence of low initial concentrations (up to 6% [vol/vol]) of O(2) in the headspace of static, horizontally incubated culture tubes; the concentration of O(2) decreased during growth in such cultures. Peroxidase, NADH oxidase, and superoxide dismutase activities were detected in the cytoplasmic fraction of cells grown in the presence of O(2). In comparison to cultures incubated under strictly anoxic conditions, acetate production decreased, higher amounts of ethanol were produced, and lactate and H(2) became significant end products when RD-1 was grown on glucose in the presence of O(2). Similarly, when RD-1 was grown on fructose in the presence of elevated salt concentrations, lower amounts of acetate and higher amounts of ethanol and H(2) were produced. When the concentration of O(2) in the headspace exceeded 1% (vol/vol), supplemental H(2) was not utilized. The 16S rRNA gene of RD-1 had a 99.7% sequence similarity to that of Clostridium glycolicum DSM 1288(T), an organism characterized as a fermentative anaerobe. Comparative experiments with C. glycolicum DSM 1288(T) demonstrated that it had negligible H(2)- and formate-utilizing capacities. However, carbon monoxide dehydrogenase was detected in both RD-1 and C. glycolicum DSM 1288(T). A 91.4% DNA-DNA hybridization between the genomic DNA of RD-1 and that of C. glycolicum DSM 1288(T) confirmed that RD-1 was a strain of C. glycolicum. These results indicate that (i) RD-1 metabolizes certain substrates via the acetyl-CoA pathway, (ii) RD-1 can tolerate and consume limited amounts of O(2), (iii) oxic conditions favor the production of ethanol, lactate, and H(2) by RD-1, and (iv) the ability of RD-1 to cope with limited amounts of O(2) might contribute to its survival in a habitat subject to daily gradients of photosynthesis-derived O(2).

Alfalfa (Medicago sativa L.) is tolerant to higher levels of salinity than previous guidelines indicated: Implications of field and greenhouse studies

NASA Astrophysics Data System (ADS)

Putnam, Daniel H.; Benes, Sharon; Galdi, Giuliano; Hutmacher, Bob; Grattan, Steve

2017-04-01

Alfalfa (Medicago sativa L.) is the most widely grown leguminous forage crop in North America and is valued for high productivity, quality, economic value, and for dairy productivity. Alfalfa has historically been classified as moderately sensitive to saline conditions, with yield declines predicted at >2 dS/m in the saturated soil paste extract. However, greenhouse, sand tank, and field studies over the past five years have confirmed that alfalfa can be grown with limited negative effects at much higher salinity levels. A broad collection of alfalfa varieties has exhibited a range of resistance at irrigation water salinities >5 dS/m ECw in greenhouse trials, with significant variation due to variety. USDA-ARS sand tank studies indicated similar or greater tolerances closer to 8 dS/m in the soil water, in addition to confirmation of significant varietal differences. A three-year field study on clay loam soil with applications of 5-7 dS/m ECw irrigation water indicated normal yields and excellent stand survivability. A second field study in the same soil type with levels from 8-10 dS/m ECw showed yield reductions of 10-15% but economic yields were still achieved at those levels. Field and greenhouse studies were conducted with mixed salt saline sodic waters typical of the San Joaquin Valley of California. Field evaluation of variety performance was subject to greater variation due to secondary salinity-soil interactions including water infiltration and crusting problems, not only salinity per-se. Thus, adequate irrigation water availability to the crop may be as important as salinity in impacting yields under field conditions. Once established, the deep-rooted characteristics of alfalfa enable utilization of deeper subsurface moisture, even at moderate to high salinity levels, as documented by USDA lysimeter studies. Significant advantages to salinity-tolerant varieties have been observed. It will be important to consider specific management factors which may enable the successful production of irrigated alfalfa with use of saline (up to 8 dS/m ECw) irrigation water, including careful water management during stand establishment, prevention of crusting, and agronomic practices to promote water infiltration. Irrigated regions looking for economically-viable crop species to grow under saline conditions may consider alfalfa grown utilizing appropriate methodologies, including salt-tolerant varieties and agronomic practices to mitigate the secondary effects of soil salinity and sodicity.

Empirical studies of regulatory restructuring and incentives

NASA Astrophysics Data System (ADS)

Knittel, Christopher Roland

This dissertation examines the actions of firms when faced with regulatory restructuring. Chapter I examines the equilibrium pricing behavior of local exchange telephone companies under a variety of market structures. In particular, the pricing behavior of three services are analyzed: residential local service, business local service, and intraLATA toll service. Beginning in 1984, a variety of market structure changes have taken place in the local telecommunications industry. I analyze differences in the method of price-setting regulation and the restrictions on entry. Specifically, the relative pricing behavior under rate of return and price cap regulation is analyzed, as well as the impact of entry in the local exchange and intraLATA toll service markets. In doing so, I estimate an empirical model that accounts for the stickiness of rates in regulated industries that is based on firm and regulator decision processes in the presence of adjustment costs. I find that, faced with competitive pressures that reduce rates in one service, incumbent firm rates increase in other services, thereby reducing the benefits from competition. In addition, the findings suggest that price cap regulation leads to higher rates relative to rate-of-return regulation. Chapter 2 analyzes the pricing and investment behavior of electricity firms. Electricity and natural gas markets have traditionally been serviced by one of two market structures. In some markets, electricity and natural gas are sold by a dual-product regulated monopolist, while in other markets, electricity and natural gas are sold by separate single-product regulated monopolies. This paper analyzes the relative pricing and investment decisions of electricity firms operating in the two market structures. The unique relationship between these two products imply that the relative incentives of single and dual-product firms are likely to differ. Namely electricity and natural gas are substitutes in consumption while natural gas is also an input into the generation of electricity. However because these firms are regulated, these differing incentives would only be acted upon if regulation is imperfect in some way. Chapter 2 analyzes these issues. In particular, I estimate equilibrium pricing and investment equations that capture the relative incentives of single and dual-product electricity firms. The results imply that both electricity prices and reliance on natural gas generation are higher in a dual-product setting, both suggesting that regulators respond to the relative incentives of electricity and natural gas firms. Chapter 3 analyzes electricity firm production incentives when regulated via performance based regulation. Although many electricity markets are currently considering adopting a competitive market for electricity generation, and still others have already done so, the vast majority of electricity markets remain tightly regulated. Within this traditional regulatory environment, the use of incentive regulation schemes in US electricity markets has grown during the past two decades. While every state has some program that it refers to as an incentive regulation program, these programs differ in both their goals and how they attempt to meet these goals. In this chapter, I discuss the wide array of programs that have been utilized to alter the incentives of US investor-owned utilities (IOUs). In addition, using stochastic frontier methods, I provide empirical analysis of the impact that a number of incentive regulation programs have on the efficiency of a large set of coal and natural gas generator units.

Prediction-based manufacturing center self-adaptive demand side energy optimization in cyber physical systems

NASA Astrophysics Data System (ADS)

Sun, Xinyao; Wang, Xue; Wu, Jiangwei; Liu, Youda

2014-05-01

Cyber physical systems(CPS) recently emerge as a new technology which can provide promising approaches to demand side management(DSM), an important capability in industrial power systems. Meanwhile, the manufacturing center is a typical industrial power subsystem with dozens of high energy consumption devices which have complex physical dynamics. DSM, integrated with CPS, is an effective methodology for solving energy optimization problems in manufacturing center. This paper presents a prediction-based manufacturing center self-adaptive energy optimization method for demand side management in cyber physical systems. To gain prior knowledge of DSM operating results, a sparse Bayesian learning based componential forecasting method is introduced to predict 24-hour electric load levels for specific industrial areas in China. From this data, a pricing strategy is designed based on short-term load forecasting results. To minimize total energy costs while guaranteeing manufacturing center service quality, an adaptive demand side energy optimization algorithm is presented. The proposed scheme is tested in a machining center energy optimization experiment. An AMI sensing system is then used to measure the demand side energy consumption of the manufacturing center. Based on the data collected from the sensing system, the load prediction-based energy optimization scheme is implemented. By employing both the PSO and the CPSO method, the problem of DSM in the manufacturing center is solved. The results of the experiment show the self-adaptive CPSO energy optimization method enhances optimization by 5% compared with the traditional PSO optimization method.

Transpiration Rate for Chile Peppers Irrigated with Brackish Groundwater and ro Concentrate

Fresh water availability is declining in most of the semi-arid and arid regions across the world including southwestern United States. Use of marginal quality groundwater has been increasing for sustaining agriculture in these arid regions. Reverse Osmosis (RO) can treat brackish groundwater but the possibility of using RO concentrate for irrigation needs further exploration. This greenhouse study evaluates the transpiration rate, water use, leaching fraction and yield responses of five selected chile pepper (Capsicum annuum) cultivars irrigated with natural brackish groundwater and RO concentrate. The four saline water treatments used for irrigation were tap water of EC 0.6 (control), ground water of EC 3 and 5 dS/m and RO concentrate of EC 8 dS/m. The transpiration of all chile peppers cultivars decreased and leaching fraction increased with increasing irrigation water salinity. Based on the water use efficiency (WUEY) of selected chile pepper cultivars, brackish water of EC ≤ 3 dS/m can be used for irrigation. The average yield of chile peppers was stable up to a saturated soil paste extract electrical conductivity (ECe) of about 2 dS/m, although further increases in ECe resulted in an exponential yield decline. This study showed that yield reductions in chile peppers irrigated with Ca rich brackish groundwater were less than those reported using NaCl dominant saline solution studies. Environmentally safe reuse of RO concentrate could stimulate implementation of inland desalination in water scarce areas and increase greenhouse chile pepper cultivation.

Soil Salinity Mapping in Everglades National Park Using Remote Sensing Techniques

The South Florida Everglades is a vast subtropical wetland with a globally unique hydrology and ecology, and it is designated as an International Biosphere Reserve and a Wetland of International Importance. Everglades National Park (ENP) is a hydro-ecologically enriched wetland with varying salinity contents, which is a concern for terrestrial ecosystem balance and sustainability. As such, in this study, time series soil salinity mapping was carried out for the ENP area. The mapping first entailed a maximum likelihood classification of seven land cover classes for the ENP area—namely mangrove forest, mangrove scrub, low-density forest, sawgrass, prairies and marshes, barren lands with woodland hammock and water—for the years 1996, 2000, 2006, 2010 and 2015. The classifications for 1996-2010 yielded accuracies of 82%-94%, and the 2015 classification was supported through ground truthing. Afterwards, electric conductivity (EC) tolerance thresholds for each vegetation class were established,which yielded soil salinity maps comprising four soil salinity classes—i.e., the non- (EC = 0 2 dS/m), low- (EC = 2 4 dS/m), moderate- (EC = 4 8 dS/m) and high-saline (EC = >8 dS/m) areas. The soil salinity maps visualized the spatial distribution of soil salinity with no significant temporal variations. The innovative approach of "land cover identification to salinity estimation" used in the study is pragmatic and application oriented, and the study upshots are also useful, considering the diversifying ecological context of the ENP area.

Identifying Pathways toward Sustainable Electricity Supply and Demand Using an Integrated Resource Strategic Planning Model for Saudi Arabia

NASA Astrophysics Data System (ADS)

Alabbas, Nabeel H.

Despite holding 16% of proved oil reserves in the world, Saudi Arabia might be on an unsustainable path to become a net oil importer by the 2030s. Decades of domestic energy subsidies accompanied by a high population growth rate have encouraged inefficient production and high domestic consumption of fossil fuel energy, which has resulted in environmental degradation, and significant social and economic consequences. In addition, the government's dependence on oil as a main source of revenue (89%) to finance its development programs cannot be sustained due to oil's exhaustible nature and rapidly increasing domestic consumption. The electricity and water sectors consume more energy than other sectors. The literature review revealed that electricity use in Saudi Arabia is following an unsustainable path (7-8% annual growth over the last decade). The water sector is another major energy consumer due to an unprecedented demand for water in the Kingdom (18% of world's total desalinated water output with per capita consumption is twice the world average). Multiple entities have been involved in fragmented planning activities on the supply-side as well as to a certain extent on the demand-side; moreover, comprehensive integrated resource strategic plans have been lacking at the national level. This dissertation established an integrated resource strategic planning (IRSP) model for Saudi Arabia's electricity and water sectors. The IRSP can clearly determine the Kingdom's future vision of its utility sector, including goals, policies, programs, and an execution timetable, taking into consideration economic, environmental and social benefits. Also, a weather-based hybrid end-use econometric demand forecasting model was developed to project electricity demand until 2040. The analytical economic efficiency and technical assessments reveal that Saudi Arabia can supply almost 75% of its electricity from renewable energy sources with a significant achievable potential for saving 26% of peak demand by 2040. However, the development of sustainable energy systems in the country's utility sector will not occur automatically. Thus, several actions are proposed for developing the sustainable energy roadmap, strategies, and policies for Saudi Arabia's utility sector, supporting its position as a new vehicle of growth that facilitates national and socio-economic development and economic diversification plan.

This report describes the results of the first phase of an investigation of the impacts of electric vehicles (EVs) in southern California. The investigation focuses on the Southern California Edison Company (SCE) which provides electric service for approximately 60% of southern California. The project is supported by the Air Quality Impacts of Energy Efficiency'' Program of the California Institute for Energy Efficiency (CIEE). The first phase of the research is organized around how EVs might be viewed by customers, vehicle manufacturers and electric utility companies. The vehicle manufacturers' view has been studied with special emphasis on the role of marketablemore » permit systems. The utilities' view of EVs is the subject of this report. The review is particularly important as several case studies of EVs in southern California have been conducted in recent years. The dynamics of a growing population of EVs is explained. Chapter 5 explains a simple method of deriving the electricity demands which could result from the operation of EVs in southern California. The method is demonstrated for several simple examples and then used to find the demands associated with each of the eight EV scenarios. Chapter 6 reports the impacts on SCE operations from the new demands for electricity. Impacts are summarized in terms of system operating costs, reliability of service, and changes in the utility's average electric rate. Chapter 7 turns to the emissions of air pollutants released by the operation of EVs, conventional vehicles (CVs) and power plants. Chapter 8 takes the air pollution analysis one step further by examining the possible reduction in ambient ozone concentration in southern California.« less

The results of electrical power system (EPS) analysis of the planned Shuttle Transportation System Flight 1 mission are presented. The capability of the orbiter EPS to support the planned flight and to provide program tape information and supplementary data specifically requested by the flight operations directorate was assessed. The analysis was accomplished using the orbiter version of the spacecraft electrical power simulator program, operating from a modified version of orbiter electrical equipment utilization baseline revision four. The results indicate that the nominal flight, as analyzed, is within the capabilities of the orbiter power generation system, but that a brief, and minimal, current overload may exist between main distributor 1 and mid power controlled 1, and that inverter 9 may the overloaded for extended periods of time. A comparison of results with launch commit criteria also indicated that some of the presently existing launch redlines may be violated during the terminal countdown.

Lessons from the Tennessee Valley Authority

NASA Astrophysics Data System (ADS)

Kitchens, Carl Thomas

This dissertation is a program evaluation of the Tennessee Valley Authority (TVA) the largest publicly owned utility in the United States. The first essay in this dissertation examines the TVA's use of eminent domain in order to acquire property for the construction of reservoirs. It develops a new model of asymmetric information and then tests the model predictions using property level data from TVA property purchases in the 1930's. The second essay of this dissertation examines the unintended consequences of reservoir development my examining changes in the malaria rate associated with TVA reservoirs. Using panel data methods, I find that the presence of a TVA reservoir leads to large increases in the malaria mortality and morbidity rate, which cost up to 30 percent of TVA federal appropriations. The final essay in this dissertation examines the impact of TVA electrification programs on economic growth. It combines archival and panel data methods to show that contrary to the historical account, TVA electric rates did not differ substantially from the rates charged by private utilities, and secondly, shows that counties that had electricity contracts with the TVA did not have differential economic growth rates for a variety of economic outcomes. In order to control for selection into contracts, I adopt an instrumental variables strategy based on the cost of electric service.

This study aimed to assess the validity and reliability of the Turkish version of Diagnostic and Statistical Manual of Mental Disorders (DSM-5) Level 2 Anger Scale. The scale was prepared by translation and back translation of DSM-5 Level 2 Anger Scale. Study groups consisted of a clinical sample of cases diagnosed with depressive disorder and treated in a child and adolescent psychiatry unit and a community sample. The study was continued with 218 children and 160 parents. In the assessment process, child and parent forms of DSM-5 Level 2 Anger Scale and Children's Depression Inventory and Strengths and Difficulties Questionnaire-Parent Form were used. In the reliability analyses, the Cronbach alpha internal consistency coefficient values were found very high regarding child and parent forms. Item-total score correlation coefficients were high and very high, respectively, for child and parent forms indicating a statistical significance. As for construct validity, one factor was maintained for each form and was found to be consistent with the original form of the scale. As for concurrent validity, the child form of the scale showed significant correlation with Children's Depression Inventory, while the parent form showed significant correlation with Strengths and Difficulties Questionnaire-Parent Form. It was found that the Turkish version of DSM-5 Level 2 Anger Scale could be utilized as a valid and reliable tool both in clinical practice and for research purposes.

Body dysmorphic disorder (BDD), a distressing or impairing preoccupation with an imagined or slight defect in appearance, has been described for more than a century and increasingly studied over the past several decades. This paper provides a focused review of issues pertaining to BDD that are relevant to DSM-V. The review presents a number of options and preliminary recommendations to be considered for DSM-V: 1) Criterion A may benefit from some rewording, without changing its focus or meaning; 2) Potential disadvantages of adding a new criterion to reflect BDD compulsive behaviors seem to outweigh potential advantages, but adding such a criterion remains an option that can be considered; 3) A clinical significance criterion seems necessary for BDD to differentiate it from normal appearance concerns; 4) BDD and eating disorders have some overlapping features and need to be differentiated; some minor changes to DSM-IV’s criterion C are suggested; 5) BDD should not be broadened to include body integrity identity disorder (apotemnophilia) or olfactory reference syndrome; 6) There is no compelling evidence for including diagnostic features or subtypes that are specific to gender-related, age-related, or cultural manifestations of BDD; 7) Adding muscle dysmorphia as a specifier may have clinical utility; and 8) The ICD-10 criteria for hypochondriacal disorder are not suitable for BDD, and there is no empirical evidence that BDD and hypochondriasis are the same disorder. The issue of how BDD’s delusional variant should be classified in DSM-V is briefly discussed and will be addressed more extensively in a separate paper. PMID:20533368

Comparing the utility of DSM-5 Section II and III antisocial personality disorder diagnostic approaches for capturing psychopathic traits.

The current study compares the 2 diagnostic approaches (Section II vs. Section III) included in the Diagnostic and Statistical Manual for Mental Disorders-5 (DSM-5; American Psychiatric Association, 2013) for diagnosis of antisocial personality disorder (ASPD) in terms of their relations with psychopathic traits and externalizing behaviors (EBs). The Section III approach to ASPD, which is more explicitly trait-based than the Section II approach, also includes a psychopathy specifier (PS) that was created with the goal of making the diagnosis of ASPD more congruent with psychopathy. In a community sample of individuals currently receiving mental health treatment (N = 106), ratings of the 2 DSM-5 diagnostic approaches were compared in relation to measures of psychopathy, as well as indices of EBs. Both DSM-5 ASPD approaches were significantly related to the psychopathy scores, although the Section III approach accounted for almost twice the amount of variance when compared with the Section II approach. Relatively little of this predictive advantage, however, was due to the PS, as these traits manifested little evidence of incremental validity in relation to existing psychopathy measures and EBs, with the exception of a measure of fearless dominance. Overall, the DSM-5 Section III diagnostic approach for ASPD is more convergent with the construct of psychopathy, from which ASPD was originally derived. These improvements, however, are due primarily to the new trait-based focus in the Section III ASPD diagnosis rather than the assessment of personality dysfunction or the inclusion of additional "psychopathy-specific" traits.

Background Since the publication of the DSM-IV in 1994, research on obsessive–compulsive disorder (OCD) has continued to expand. It is timely to reconsider the nosology of this disorder, assessing whether changes to diagnostic criteria as well as subtypes and specifiers may improve diagnostic validity and clinical utility. Methods The existing criteria were evaluated. Key issues were identified. Electronic databases of PubMed, ScienceDirect, and PsycINFO were searched for relevant studies. Results This review presents a number of options and preliminary recommendations to be considered for DSM-V. These include: (1) clarifying and simplifying the definition of obsessions and compulsions(criterion A); (2) possibly deleting the requirement that people recognize that their obsessions or compulsions are excessive or unreasonable (criterion B); (3) rethinking the clinical significance criterion (criterion C) and, in the interim, possibly adjusting what is considered “time-consuming” for OCD; (4) listing additional disorders to help with the differential diagnosis (criterion D); (5) rethinking the medical exclusion criterion (criterion E) and clarifying what is meant by a “general medical condition”; (6) revising the specifiers (i.e., clarifying that OCD can involve a range of insight, in addition to “poor insight,” and adding “tic-related OCD”); and (7) highlighting in the DSM-V text important clinical features of OCD that are not currently mentioned in the criteria (e.g., the major symptom dimensions). Conclusions A number of changes to the existing diagnostic criteria for OCD are proposed. These proposed criteria may change as the DSM-V process progresses. PMID:20217853

1982-01-01

A program is being conducted to develop the technology required to utilize fuels with broadened properties in aircraft gas turbine engines. The first phase of this program consisted of the experimental evaluation of three different combustor concepts to determine their potential for meeting several specific emissions and performance goals, when operated on broadened property fuels. The three concepts were a single annular combustor; a double annular combustor; and a short single annular combustor with variable geometry. All of these concepts were sized for the General Electric CF6-80 engine. A total of 24 different configurations of these concepts were evaluated in a high pressure test facility, using four test fuels having hydrogen contents between 11.8 and 14%. Fuel effects on combustor performance, durability and emissions, and combustor design features to offset these effects were demonstrated.

Risk factors among adolescent substance abusers have been shown to correlate with substance use severity. Characteristics related to severity, such as demographic and family factors, peer influences, psychiatric co-morbidity and HIV risk behaviors, are examined for a sample of adolescent cannabis users entering treatment. These data are from a clinical trial study utilizing blocked random assignment of clients to one of five treatment conditions. The study targeted adolescents entering outpatient treatment for primarily cannabis abuse or dependence. Treatment and research facilities in four metropolitan areas of the US were used to recruit study participants. Treatment was delivered in outpatient drug-free settings. Participants were 600 clients, ages 12-18, admitted to outpatient substance abuse treatment programs for cannabis problems, 96% with DSM-IV diagnoses of substance abuse or dependence, with the remaining 4% having at least one symptom of dependence plus significant problems indicating need for treatment. The Global Appraisal of Individual Needs (GAIN) was used to collect the information presented in this paper. The GAIN incorporates DSM-IV criteria for substance use disorders, conduct disorder and attention deficit hyperactivity disorder, as well as dimensional (scale) measures for physical and mental health. All participants reported at least one symptom of substance use disorders, and 46% met the DSM-IV criteria for substance dependence, while 50% met criteria for a diagnosis of abuse. Only 20% of the participants perceived any need for help with problems associated with their drug or alcohol use. Clients participating in the study typically presented multiple problems at treatment entry, most often including conduct disorder, attention deficit hyperactivity disorder (ADHD), internal (mental) distress, and physical health distress. The co-occurrence of conduct disorder and ADHD was found in 30% of the sample. Clients meeting criteria for substance dependence tended to have more co-occurring problems and significantly less denial at admission. The characteristics of this sample exemplify the complex nature of adolescent substance use and abuse among adolescents entering outpatient treatment programs. Patterns of co-occurring problems are at rates comparable to those found in other clinical studies. Those with more severe substance use disorders tend to manifest more problems of social functioning, more mental health problems, and physical health problems. Implications of these findings are discussed in terms of treatment needs, challenges, and prognostic implications.

Werner, L. B.

1974-01-01

Within the overall federal geothermal program, the Atomic Energy Commission has chosen to concentrate on development of resource utilization and advanced research and technology as the areas most suitable to the expertise of its staff and that of the National Laboratories. The Commission's work in geothermal energy is coordinated with that of other agencies by the National Science Foundation, which has been assigned lead agency by the Office of Management and Budget. The objective of the Commission's program, consistent with the goals of the total federal program is to facilitate, through technological advancement and pilot plant operations, achievement of substantial commercial production of electrical power and utilization of geothermal heat by the year 1985. This will hopefully be accomplished by providing, in conjunction with industry, credible information on the economic operation and technological reliability of geothermal power and use of geothermal heat.

Utilization of Silicon-Oxide-Nitride-Oxide-Silicon (SONOS) nonvolatile semiconductor memories as a flash memory has many advantages. These electrically erasable programmable read-only memories (EEPROMs) utilize low programming voltages, have a high erase/write cycle lifetime, are radiation hardened, and are compatible with high-density scaled CMOS for low power, portable electronics. In this paper, the SONOS memory cell erase cycle was investigated using a nonquasi-static (NQS) MOSFET model. Comparisons were made between the model predictions and experimental data.

Estimating customer electricity savings from projects installed by the U.S. ESCO industry

DOE Office of Scientific and Technical Information (OSTI.GOV)

Carvallo, Juan Pablo; Larsen, Peter H.; Goldman, Charles A.

The U.S. energy service company (ESCO) industry has a well-established track record of delivering substantial energy and dollar savings in the public and institutional facilities sector, typically through the use of energy savings performance contracts (ESPC) (Larsen et al. 2012; Goldman et al. 2005; Hopper et al. 2005, Stuart et al. 2013). This ~$6.4 billion industry, which is expected to grow significantly over the next five years, may play an important role in achieving demand-side energy efficiency under local/state/federal environmental policy goals. To date, there has been little or no research in the public domain to estimate electricity savings formore » the entire U.S. ESCO industry. Estimating these savings levels is a foundational step in order to determine total avoided greenhouse gas (GHG) emissions from demand-side energy efficiency measures installed by U.S. ESCOs. We introduce a method to estimate the total amount of electricity saved by projects implemented by the U.S. ESCO industry using the Lawrence Berkeley National Laboratory (LBNL) /National Association of Energy Service Companies (NAESCO) database of projects and LBNL’s biennial industry survey. We report two metrics: incremental electricity savings and savings from ESCO projects that are active in a given year (e.g., 2012). Overall, we estimate that in 2012 active U.S. ESCO industry projects generated about 34 TWh of electricity savings—15 TWh of these electricity savings were for MUSH market customers who did not rely on utility customer-funded energy efficiency programs (see Figure 1). This analysis shows that almost two-thirds of 2012 electricity savings in municipal, local and state government facilities, universities/colleges, K-12 schools, and healthcare facilities (i.e., the so-called “MUSH” market) were not supported by a utility customer-funded energy efficiency program.« less

Dynamics of amino acid utilization in Phaeobacter inhibens DSM 17395.

Time-resolved utilization of multiple amino acids by Phaeobacter inhibens DSM 17395 was studied during growth with casamino acids. The 15 detected amino acids could be grouped according to depletion rate into four different categories, i.e. from rapid (category I) to nondepletion (category IV). Upon entry into stationary growth phase, amino acids of category I (e.g. glutamate) were (almost) completely depleted, while those of categories II (e.g. leucine) and III (e.g. serine) were further consumed at varying rates and to different extents. Thus, cultures entered stationary growth phase despite the ample presence of organic nutrients, i.e. under nonlimiting conditions. Integrated proteomic and metabolomic analysis identified 1747 proteins and 94 intracellular metabolites. Of these, 180 proteins and 86 metabolites displayed altered abundance levels during growth. Most strikingly, abundance and activity profiles of alanine dehydrogenase concomitantly increased with the onset of enhanced alanine utilization during transition into stationary growth phase. Most enzymes of amino acid and central metabolism, however, displayed unaltered abundances across exponential and stationary growth phases. In contrast, metabolites of the Entner-Doudoroff pathway and gluconeogenesis as well as cellular fatty acids increased markedly in abundance in early stationary growth phase. © 2013 WILEY-VCH Verlag GmbH & Co.

2017-02-07

A predictive-control approach allows an electricity provider to monitor and proactively manage peak and off-peak residential intra-day electricity usage in an emerging smart energy grid using time-dependent dynamic pricing incentives. The daily load is modeled as time-shifted, but cost-differentiated and substitutable, copies of the continuously-consumed electricity resource, and a consumer-choice prediction model is constructed to forecast the corresponding intra-day shares of total daily load according to this model. This is embedded within an optimization framework for managing the daily electricity usage. A series of transformations are employed, including the reformulation-linearization technique (RLT) to obtain a Mixed-Integer Programming (MIP) model representation of the resulting nonlinear optimization problem. In addition, various regulatory and pricing constraints are incorporated in conjunction with the specified profit and capacity utilization objectives.

A total of 195 admissions to a child psychiatric inpatient unit were diagnosed independently by two to four clinicians on the basis of case presentations at the first ward-round after admission. The DSM III as a whole and the major categories were of high or acceptable reliability, though a few were clearly unreliable. The results are generally consistent with other studies. Unlike other studies, the subcategories were examined and found to vary widely in reliability both as a whole across the system and within parent major categories, throwing considerable doubt upon their utility. The results indicate the need both for improved diagnostic data-gathering techniques in child psychiatry and for more better-designed studies of reliability and, most necessarily, of validity.

An additional NUWC concern is a proposed rate change by the servicing utility, Newport Electric, which would make a significant shift from consumption to demand billing, and what effect that rate change would have on the NUWC utility budget. Automated, remote reading meters are available which would allow NUWC tomore » monitor its actual utility consumption and demand for both the entire NUWC compound and by end-use in individual buildings. Technology is available to perform the meter reads and manipulate the data using a personal computer with minimal staff requirement. This is not meant to mislead the reader into assuming that there is no requirement for routine preventive maintenance. All equipment requires routine maintenance to maintain its accuracy. While PNL reviewed the data collected during the site visit, however, it became obvious that significant opportunities exist for reducing the utility costs other than accounting for actual consumption and demand.

Strain NL19T is a Gram-stain-negative, aerobic bacterium that was isolated from sludge of a deactivated uranium mine in Portugal. 16S rRNA gene sequence analysis revealed that strain NL19T is a member of the genus Pedobacter and closely related to the strains Pedobacter himalayensis MTCC 6384T, Pedobacter cryoconitis DSM 14825T, Pedobacter westerhofensis DSM 19036T and Pedobacterhartonius DSM 19033T. It had a DNA G+C content of 40.8 mol%, which agreed with the genus description. The main fatty acids included C16 : 1ω7c, C14 : 1ω5c, C4 : 0, iso-C17 : 0, iso-C17 : 0 3-OH, C16 : 0, anteiso-C15 : 0 and iso-C15 : 0 3-OH. The main lipids present were phospholipids (60 %) and sphingolipids (35 %). The most abundant phospholipids included phosphatidylethanolamine, phosphatidylinositol and phosphatidylcholine. Menaquinone-7 (MK-7) was the only isoprenoid quinone detected. DNA-DNA hybridization similarities between strain NL19T and Pedobacter himalayensis MTCC 6384T, Pedobacter cryoconitis DSM 14825T, Pedobacter westerhofensis DSM 19036T and Pedobacter hartonius DSM 19033T were 15.3 , 16.2 , 11.5 and 16.0 %, respectively. Strain NL19T can also be distinguished from these four species based on gyrB and intergenic transcribed spacers (ITS) sequences and by some phenotypic traits such as NaCl tolerance, pH, growth temperature and carbon source utilization. Strain NL19Trepresents a novel species of the genus Pedobacter, for which the name Pedobacter lusitanus sp. nov. is proposed. The type strain is NL19T (=LMG 29220T=CECT 9028T). An amended description of Pedobacter himalayensis is also included.

Objective: The aim of this study was to examine psychometric properties of the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV), diagnostics criteria for alcohol and marijuana dependences among 462 alcohol users and 311 marijuana users enrolled in two multisite trials of the National Drug Abuse Treatment Clinical Trials Network. Method: Diagnostic questions were assessed by the DSM-IV checklist. Data were analyzed by the item response theory and the multiple indicators–multiple causes method procedures. Results: Criterion symptoms of alcohol and marijuana dependences exhibited a high level of internal consistency. All individual symptoms showed good discrimination in distinguishing alcohol or marijuana users between high and low severity levels of the continuum. In both groups, “withdrawal” appeared to measure the most severe symptom of the dependence continuum. There was little evidence of measurement nonequivalence in assessing symptoms of dependence by gender, age, race/ethnicity, and educational level. Conclusions: These findings highlight the clinical utility of the DSM-IV checklist in assessing alcohol- and marijuana-dependence syndromes among treatment-seeking substance users. PMID:19371493

[Diagnostic validity of attention deficit/hyperactivity disorder: from phenomenology to neurobiology (I)].

Trujillo-Orrego, N; Pineda, D A; Uribe, L H

2012-03-01

The diagnostic criteria for the attentional deficit hyperactivity disorder (ADHD), were defined by the American Psychiatric Association in the Diagnostic and Statistical Manual of Mental Disorders fourth version (DSM-IV) and World Health Organization in the ICD-10. The American Psychiatric Association used an internal validity analysis to select specific behavioral symptoms associated with the disorder and to build five cross-cultural criteria for its use in the categorical diagnosis. The DSM has been utilized for clinicians and researchers as a valid and stable approach since 1968. We did a systematic review of scientific literature in Spanish and English, aimed to identify the historical origin that supports ADHD as a psychiatric construct. This comprehensive review started exploring the concept of minimal brain dysfunction, hyper-activity, inattention, impulsivity since 1932 to 2011. This paper summarize all the DSM versions that include the definition of ADHD or its equivalent, and it point out the statistical and methodological approach implemented for defining ADHD as a valid epidemiological and psychometric construct. Finally the paper discusses some considerations and suggestions for the new versions of the manual.

A comparison of obsessive-compulsive personality disorder scales.

Samuel, Douglas B; Widiger, Thomas A

2010-05-01

In this study, we utilized a large undergraduate sample (N = 536), oversampled for the Diagnostic and Statistical Manual of Mental Disorders (4th ed., text revision [DSM-IV-TR]; American Psychiatric Association, 2000) obsessive-compulsive personality disorder (OCPD) pathology, to compare 8 self-report measures of OCPD. No prior study has compared more than 3 measures, and the results indicate that the scales had only moderate convergent validity. We also went beyond the existing literature to compare these scales to 2 external reference points: their relationships with a well-established measure of the five-factor model of personality (FFM) and clinicians' ratings of their coverage of the DSM-IV-TR criterion set. When the FFM was used as a point of comparison, the results suggest important differences among the measures with respect to their divergent representation of conscientiousness, neuroticism, and agreeableness. Additionally, an analysis of the construct coverage indicated that the measures also varied in terms of their representation of particular diagnostic criteria. For example, whereas some scales contained items distributed across the diagnostic criteria, others were concentrated more heavily on particular features of the DSM-IV-TR disorder.

Revising the personality disorder diagnostic criteria for the Diagnostic and Statistical Manual of Mental Disorders-Fifth Edition (DSM-V): consider the later life context.

PubMed

Balsis, Steve; Segal, Daniel L; Donahue, Cailin

2009-10-01

The categorical measurement approach implemented by the Diagnostic and Statistical Manual of Mental Disorders-Fourth Edition (DSM-IV) personality disorder (PD) diagnostic system is theoretically and pragmatically limited. As a result, many prominent psychologists now advocate for a shift away from this approach in favor of more conceptually sound dimensional measurement. This shift is expected to improve the psychometric properties of the personality disorder (PD) diagnostic system and make it more useful for clinicians and researchers. The current article suggests that despite the probable benefits of such a change, several limitations will remain if the new diagnostic system does not closely consider the context of later life. A failure to address the unique challenges associated with the assessment of personality in older adults likely will result in the continued limited validity, reliability, and utility of the Diagnostic and Statistical Manual of Mental Disorders (DSM) system for this growing population. This article discusses these limitations and their possible implications. (c) 2009 APA, all rights reserved.

Pedophilia: an evaluation of diagnostic and risk prediction methods.

2011-06-01

One hundred thirty child sexual abusers were diagnosed using each of following four methods: (a) phallometric testing, (b) strict application of Diagnostic and Statistical Manual of Mental Disorders (4th ed., text revision [DSM-IV-TR]) criteria, (c) Rapid Risk Assessment of Sex Offender Recidivism (RRASOR) scores, and (d) "expert" diagnoses rendered by a seasoned clinician. Comparative utility and intermethod consistency of these methods are reported, along with recidivism data indicating predictive validity for risk management. Results suggest that inconsistency exists in diagnosing pedophilia, leading to diminished accuracy in risk assessment. Although the RRASOR and DSM-IV-TR methods were significantly correlated with expert ratings, RRASOR and DSM-IV-TR were unrelated to each other. Deviant arousal was not associated with any of the other methods. Only the expert ratings and RRASOR scores were predictive of sexual recidivism. Logistic regression analyses showed that expert diagnosis did not add to prediction of sexual offence recidivism over and above RRASOR alone. Findings are discussed within a context of encouragement of clinical consistency and evidence-based practice regarding treatment and risk management of those who sexually abuse children.

Light oil from pyrolysis, which accounts for ~10 % carbon yield of the starting biomass, is a complex aqueous product that is difficult to utilize and usually discarded. This work presents the feasibility of light oil as a sole carbon source to support the growth of Rhodococcus opacus (R. opacus) that in turn accumulate triacylglycerols as biodiesel feedstock. Two types of bacteria (R. opacus PD630 and DSM 1069) were selected in this study. Research results showed that after short adaption periods both strains can grow well on this complex carbon source, as proved by the consumption of oligomers and monomersmore » in light oil. Lipid content by R. opacus PD630 and DSM 1069 was observed up to 25.8 % and 22.0 % of cell dry weight, respectively. Palmitic and stearic acids were found to be the predominant fatty acids in these bacterial cells. In addition, the light oil-based lipid production can be enhanced by reducing the pH value from 7 to 4, especially in case of DSM 1069.« less

Community Solar Value Project

Powers, John T.; Cliburn, Jill

The Community Solar Value Project (CSVP) is designed to assist electric utilities in designing better community solar programs. Better programs seek new sources of value to promote “win-win” solutions between utilities and their customers. The CSVP focused on five “challenge areas” in identifying new sources of value: - Strategic solar design for community solar projects (including technology choices, siting, orientation, and related issues) - Market research and targeted marketing approaches (for program design and for customer recruitment) - Procurement and financing (for establishing best practices that can bring economies of scale and economies of expertise) - Integration of “companion measures”more » (such as storage and demand-response options that can benefit customer and utility net load shapes) - Pricing in program design (including best practices for integration of identified value in program prices or credits) The CSVP directly engaged the Sacramento Municipal Utility District (SMUD), the Public Service Company of New Mexico (PNM), and more than a dozen other utilities to develop improved community solar program designs. The outcomes include a plan at SMUD for over 100 MW or more of community and shared solar and support for new or expanded programs at 15 other utilities so far. Resulting best-practice solutions have not only informed program applications, but also have generated discussion among experts and industry associations about the new opportunities and challenges CSVP has brought forth. In these ways, the CSVP has impacted community solar programs and DER plans, competitive innovations and policies nationwide. The CSVP team has been led by Extensible Energy under John Powers, President and CEO. Jill Cliburn, of Santa Fe, NM-based Cliburn and Associates, has served as Principal Investigator. The team also benefitted from expertise from Navigant, Olivine Inc. and Millennium Energy, LLC, in addition to the collaborative and cost-sharing contributions of its utility partners. The CSVP team participated fully in the Solar Market Pathways Program, which was initiated under the U.S. Department of Energy SunShot program and reports to the U.S. Department of Energy Solar Energy Technologies Office. This report summarizes a multi-disciplinary project that took place over 33 months from January, 2015 through September, 2017.« less

Objective To examine three aspects of adolescent cannabis problems: 1) do DSM-IV cannabis abuse and dependence criteria represent two different levels of severity of substance involvement, 2) to what degree do each of the 11 abuse and dependence criteria assess adolescent cannabis problems, and 3) do the DSM-IV items function similarly across different adolescent populations? Method We examined 5587 adolescents aged 11–19, including 615 youth in treatment for substance use disorders, 179 adjudicated youth, and 4793 youth from the community. All subjects were assessed with a structured diagnostic interview. Item response theory was utilized to analyze symptom endorsement patterns. Results Abuse and dependence criteria were not found to represent different levels of severity of problem cannabis use in any of the samples. Among the 11 abuse and dependence criteria, Problems cutting down and Legal problems were the least informative for distinguishing problem users. Two dependence criteria and three of the four abuse criteria indicated different severities of cannabis problems across samples. Conclusions We found little evidence to support the idea that abuse and dependence are separate constructs for adolescent cannabis problems. Furthermore, certain abuse criteria may indicate severe substance problems while specific dependence items may indicate less severe problems. The abuse items in particular need further study. These results have implications for the refinement of the current substance use disorder criteria for DSM-V. PMID:18176333

Depression is more than the sum-score of its parts: individual DSM symptoms have different risk factors

PubMed Central

Fried, Eiko I.; Nesse, Randolph M.; Zivin, Kara; Guille, Constance; Sen, Srijan

2014-01-01

Background For diagnostic purposes, the nine symptoms that compose the DSM-5 criteria for Major Depressive Disorder (MDD) are assumed to be interchangeable indicators of one underlying disorder, implying that they should all have similar risk factors. The present study investigates this hypothesis, utilizing a population cohort that shifts from low to elevated depression levels. Methods We assessed the nine DSM-5 MDD criterion symptoms and seven depression risk factors (personal and family MDD history, sex, childhood stress, neuroticism, work hours, and stressful life events) in a longitudinal study of medical interns prior to and throughout internship (n=1289). We tested if risk factors varied across symptoms, and whether a latent disease model could account for heterogeneity between symptoms. Results All MDD symptoms increased significantly during residency training. Four risk factors predicted increases in unique subsets of PHQ-9 symptoms over time (depression history, childhood stress, sex, and stressful life events), while neuroticism and work hours predicted increases in all symptoms, albeit to varying magnitudes. MDD family history did not predict increases in any symptom. The strong heterogeneity of associations persisted after controlling for a latent depression factor. Conclusions The influence of risk factors varies substantially across DSM depression criterion symptoms. Since symptoms are etiologically heterogeneous, considering individual symptoms in addition to depression diagnosis might offer important insights obfuscated by symptom sum-scores. PMID:24289852

Should A2 be a diagnostic requirement for posttraumatic stress disorder in DSM-V?

2010-04-30

The requirement that trauma survivors experience fear, helplessness or horror (Criterion A2) as a part of their posttraumatic stress disorder (PTSD) diagnosis was introduced into DSM-IV. The imminent re-definition of PTSD in DSM-V highlights the need for empirical studies to validate the utility of the A2 requirement. We aimed to identify (i) how often A2 was associated with PTSD (B-F criteria) at 3 months after trauma and (ii) what was the peritraumatic emotional experience for those who met PTSD criteria but were A2 negative. In a prospective design cohort study we assessed the peritraumatic emotional experience of 535 injury patients in four Australian hospitals. These patients were followed up 3 months later and assessed for PTSD using a structured clinical interview. The majority of those who developed PTSD (B-F criterion) at 3 months met A2 criteria. A substantial minority, however (23%), did not meet A2 criteria. Those PTSD patients who were A2 negative fell into three groups: (i) those who experienced subthreshold levels of A2; (ii) those who experienced intense peritrauma emotional responses other than fear, helplessness or horror; and (iii) those who were amnesic to their peritrauma emotional experience. These findings do not support the inclusion of A2 as diagnostic requirement for DSM-V. Copyright (c) 2009 Elsevier Ireland Ltd. All rights reserved.

The American Psychiatric Association has revised the diagnostic criteria for their DSM-5 manual. Important changes have been made to the diagnosis of the current (DSM-IV) category of Pervasive Developmental Disorders. This category includes Autistic Disorder (autism), Asperger's Disorder, and Pervasive Developmental Disorder Not Otherwise Specified (PDD-NOS). The DSM-5 deletes Asperger's Disorder and PDD-NOS as diagnostic entities. This change may have unintended consequences, including the possibility that the new diagnostic framework will adversely affect access to developmental interventions under Individuals with Disabilities Education Act (IDEA) programs, Early Intervention (for birth to 2 years olds) and preschool special education (for 3 and 4 years olds). Changing the current diagnosis of PDD-NOS to a "Social Communication Disorder" focused on language pragmatics in the DSM-5 may restrict eligibility for IDEA programs and limit the scope of services for affected children. Young children who meet current criteria for PDD-NOS require more intensive and multi-disciplinary services than would be available with a communication domain diagnosis and possible service authorization limited to speech-language therapy. Intensive behavioral interventions, inclusive group setting placements, and family support services are typically more available for children with an autism spectrum disorder than with diagnoses reflecting speech-language delay. The diagnostic distinction reflective of the higher language and social functioning between Asperger's Disorder and autism is also undermined by eliminating the former as a categorical diagnosis and subsuming it under autism. This change may adversely affect treatment planning and misinform parents about prognosis for children who meet current criteria for Asperger's Disorder.

Our report presents the permanent draft genome sequence of Desulfurococcus mobilis type strain DSM 2161, an obligate anaerobic hyperthermophilic crenarchaeon that was isolated from acidic hot springs in Hveravellir, Iceland. D. mobilis utilizes peptides as carbon and energy sources and reduces elemental sulfur to H 2S. A metabolic construction derived from the draft genome identified putative pathways for peptide degradation and sulfur respiration in this archaeon. Existence of several hydrogenase genes in the genome supported previous findings that H 2 is produced during the growth of D. mobilis in the absence of sulfur. Interestingly, genes encoding glucose transport and utilizationmore » systems also exist in the D. mobilis genome though this archaeon does not utilize carbohydrate for growth. The draft genome of D. mobilis provides an additional mean for comparative genomic analysis of desulfurococci. In addition, our analysis on the Average Nucleotide Identity between D. mobilis and Desulfurococcus mucosus suggested that these two desulfurococci are two different strains of the same species.« less

The objective of this study was to assess the strengths and limitations of a mixed bipolar depression definition made more inclusive than that of the Diagnostic and Statistical Manual of Mental Disorders Fifth Edition (DSM-5) by counting not only 'non-overlapping' mood elevation symptoms (NOMES) as in DSM-5, but also 'overlapping' mood elevation symptoms (OMES, psychomotor agitation, distractibility, and irritability). Among bipolar disorder (BD) out-patients assessed with the Systematic Treatment Enhancement Program for BD (STEP-BD) Affective Disorders Evaluation, we assessed prevalence, demographics, and clinical correlates of mixed vs. pure depression, using more inclusive (≥3 NOMES/OMES) and less inclusive DSM-5 (≥3 NOMES) definitions. Among 153 depressed BD, counting not only NOMES but also OMES yielded a three-fold higher mixed depression rate (22.9% vs. 7.2%) and important statistically significant clinical correlates for mixed compared to pure depression (more lifetime anxiety disorder comorbidity, more current irritability, and less current antidepressant use), which were not significant using the DSM-5 threshold. To conclude, further studies with larger numbers of patients with DSM-5 bipolar mixed depression assessing strengths and limitations of more inclusive mixed depression definitions are warranted, including efforts to ascertain whether or not OMES should count toward mixed depression. © 2016 John Wiley & Sons A/S.

Coccaro, Emil F

2018-04-30

This study was designed to estimate how many adults with DSM-5 Intermittent Explosive Disorder (IED) would also meet diagnostic criteria for Disruptive Mood Dysregulation Disorder (DMDD). This was done by examining how many individuals with IED would meet the DMDD criterion of being persistently angry in between impulsive aggressive outbursts. The first one-hundred study participants diagnosed with DSM-5 IED in our clinical research program were included in this study. Two questions were added to the IED module from the Structured Clinical Interview for DSM-5 Disorders (SCID) inquiring about the duration of anger in between impulsive aggressive outbursts in IED study participants. Data regarding aggression, impulsivity, anger expression, and related dysphoric variables were also collected. The proportion of time spent as angry in between impulsive aggressive outbursts was <50% of the time (~35%) for the vast majority (92%) of study participants with DSM-5 IED. Despite this, persistently-angry (i.e., angry >50% time in between outbursts) IED study participants displayed no differences from not-persistently-angry IED study participants in dysphoric and aggression/impulsivity related variables. These data indicate that inter-outburst anger in those with IED is relatively brief and that such individuals do not generally display the kind of persistent anger that is a diagnostic feature of DMDD.

The availability of qualified safety related replacement parts for use in nuclear power plants has decreased over time. This has caused many nuclear power plants to purchase commercial grade items (CGI) and utilize the commercial grade dedication process to qualify the items for use in nuclear safety related applications. The laboratories of Technical and Engineering Services (the testing facility of Detroit Edison) have been providing testing services for verification of critical characteristics of these items. This paper presents an overview of the experience in testing electrical equipment with an emphasis on fuses.

As presented by Gerhard Heller of Marshall Space Flight Center's Research Projects Division in 1961, this chart illustrates three basic types of electric propulsion systems then under consideration by NASA. The ion engine (top) utilized cesium atoms ionized by hot tungsten and accelerated by an electrostatic field to produce thrust. The arc engine (middle) achieved propulsion by heating a propellant with an electric arc and then producing an expansion of the hot gas or plasma in a convergent-divergent duct. The electromagnetic, or MFD engine (bottom) manipulated strong magnetic fields to interact with a plasma and produce acceleration.

The 1997 edition of the ``Financial Statistics of Major U.S. Publicly Owned Electric Utilities`` publication presents 5 years (1993 through 1997) of summary financial data and current year detailed financial data on the major publicly owned electric utilities. The objective of the publication is to provide Federal and State governments, industry, and the general public with current and historical data that can be used for policymaking and decisionmaking purposes related to publicly owned electric utility issues. Generator (Tables 3 through 11) and nongenerator (Tables 12 through 20) summaries are presented in this publication. Five years of summary financial data aremore » provided (Tables 5 through 11 and 14 through 20). Summaries of generators for fiscal years ending June 30 and December 31, nongenerators for fiscal years ending June 30 and December 31, and summaries of all respondents are provided in Appendix C. The composite tables present aggregates of income statement and balance sheet data, as well as financial indicators. Composite tables also display electric operation and maintenance expenses, electric utility plant, number of consumers, sales of electricity, operating revenue, and electric energy account data. The primary source of publicly owned financial data is the Form EIA-412, ``Annual Report of Public Electric Utilities.`` Public electric utilities file this survey on a fiscal year basis, in conformance with their recordkeeping practices. The EIA undertook a review of the Form EIA-412 submissions to determine if alternative classifications of publicly owned electric utilities would permit the inclusion of all respondents. The review indicated that financial indicators differ most according to whether or not a publicly owned electric utility generates electricity. Therefore, the main body of the report provides summary information in generator/nongenerator classifications. 2 figs., 101 tabs.« less

EPRI guide to managing nuclear utility protective clothing programs

Kelly, J.J.

1991-05-01

The Electric Power Research Institute (EPRI) commissioned a radioactive waste related project (RP2414-34) during the last quarter of 1989 to produce a guide for developing and managing nuclear protective clothing programs. Every nuclear facility must coordinate some type of protective clothing program for its radiation workers to insure proper and safe protection for the wearer and to maintain control over the spread of contamination. Yet, every nuclear facility has developed its own unique program for managing such clothing. Accordingly, a need existed for a reference guide to assist with the standardization of protective clothing programs and to assist in controllingmore » the potentially runaway economics of such programs. This document is the first known effort to formalize the planning and economic factors surrounding a nuclear utility protective clothing program. It is intended to be informative by addressing the various pieces of information necessary to establish and maintain an effective, professionally managed protective clothing program. It also attempts to provide guidance toward tailoring the information and providing examples within the report to fit each utility's specific needs. This report is further intended to address new issues and trends occurring throughout the nuclear industry in late 1989 which can have either a significant positive or negative impact on the operations or economics of nuclear protective clothing programs. 1 ref., 11 tabs.« less

Automated Demand Response Approaches to Household Energy Management in a Smart Grid Environment

NASA Astrophysics Data System (ADS)

Adika, Christopher Otieno

The advancement of renewable energy technologies and the deregulation of the electricity market have seen the emergence of Demand response (DR) programs. Demand response is a cost-effective load management strategy which enables the electricity suppliers to maintain the integrity of the power grid during high peak periods, when the customers' electrical load is high. DR programs are designed to influence electricity users to alter their normal consumption patterns by offering them financial incentives. A well designed incentive-based DR scheme that offer competitive electricity pricing structure can result in numerous benefits to all the players in the electricity market. Lower power consumption during peak periods will significantly enhance the robustness of constrained networks by reducing the level of power of generation and transmission infrastructure needed to provide electric service. Therefore, this will ease the pressure of building new power networks as we avoiding costly energy procurements thereby translating into huge financial savings for the power suppliers. Peak load reduction will also reduce the inconveniences suffered by end users as a result of brownouts or blackouts. Demand response will also drastically lower the price peaks associated with wholesale markets. This will in turn reduce the electricity costs and risks for all the players in the energy market. Additionally, DR is environmentally friendly since it enhances the flexibility of the power grid through accommodation of renewable energy resources. Despite its many benefits, DR has not been embraced by most electricity networks. This can be attributed to the fact that the existing programs do not provide enough incentives to the end users and, therefore, most electricity users are not willing to participate in them. To overcome these challenges, most utilities are coming up with innovative strategies that will be more attractive to their customers. Thus, this dissertation presents various demand response schemes that can be deployed by electricity providers to manage customer loads. This study also addresses the problem of manual demand response by proposing smart systems that will autonomously execute the DR programs without the direct involvement of the customers.

MoisturEC: an R application for geostatistical estimation of moisture content from electrical conductivity data

Soil moisture is a critical parameter for agriculture, water supply, and management of landfills. Whereas direct data (as from TDR or soil moisture probes) provide localized point scale information, it is often more desirable to produce 2D and/or 3D estimates of soil moisture from noninvasive measurements. To this end, geophysical methods for indirectly assessing soil moisture have great potential, yet are limited in terms of quantitative interpretation due to uncertainty in petrophysical transformations and inherent limitations in resolution. Simple tools to produce soil moisture estimates from geophysical data are lacking. We present a new standalone program, MoisturEC, for estimating moisture content distributions from electrical conductivity data. The program uses an indicator kriging method within a geostatistical framework to incorporate hard data (as from moisture probes) and soft data (as from electrical resistivity imaging or electromagnetic induction) to produce estimates of moisture content and uncertainty. The program features data visualization and output options as well as a module for calibrating electrical conductivity with moisture content to improve estimates. The user-friendly program is written in R - a widely used, cross-platform, open source programming language that lends itself to further development and customization. We demonstrate use of the program with a numerical experiment as well as a controlled field irrigation experiment. Results produced from the combined geostatistical framework of MoisturEC show improved estimates of moisture content compared to those generated from individual datasets. This application provides a convenient and efficient means for integrating various data types and has broad utility to soil moisture monitoring in landfills, agriculture, and other problems.

Dedication file preparation for commercial-grade electric components

1988-01-01

Dedication is the process of making a commercial-grade item into a basic component that can be installed in safety systems. This process ensures that the commercially manufactured items are of the same or equivalent form, fit, function, and materials as the originally provided safety item. This process must ensure that the original utility's equipment qualification program is maintained per licensing commitments to 10CFR50.49 and general design criterion No. 4. Today, utilities recognize the need for establishing a dedication program to provide the flexibility in obtaining replacement items directly from the original manufacturers. This need has arisen because (a) most systemmore » houses, large manufacturers, and component manufacturers will sell their products only through distributors as straight commercial-grade items or only service former clients, and (b) lack of competition for specific safety-related items has resulted in excessive hardware cost and very long delivery schedules, which could affect plant availability. The vehicle for utilities to obtain safety-related items is to establish and manage a comprehensive dedication program for their own use or provide the direction for a nuclear supplier to follow. This paper provides both utilities and nuclear suppliers insight into the complexities of a dedication program. This insight is provided from our experience as a utilities agent and as a third-party nuclear supplier.« less

Optimization Based Data Mining Approah for Forecasting Real-Time Energy Demand

DOE Office of Scientific and Technical Information (OSTI.GOV)

Omitaomu, Olufemi A; Li, Xueping; Zhou, Shengchao

The worldwide concern over environmental degradation, increasing pressure on electric utility companies to meet peak energy demand, and the requirement to avoid purchasing power from the real-time energy market are motivating the utility companies to explore new approaches for forecasting energy demand. Until now, most approaches for forecasting energy demand rely on monthly electrical consumption data. The emergence of smart meters data is changing the data space for electric utility companies, and creating opportunities for utility companies to collect and analyze energy consumption data at a much finer temporal resolution of at least 15-minutes interval. While the data granularity providedmore » by smart meters is important, there are still other challenges in forecasting energy demand; these challenges include lack of information about appliances usage and occupants behavior. Consequently, in this paper, we develop an optimization based data mining approach for forecasting real-time energy demand using smart meters data. The objective of our approach is to develop a robust estimation of energy demand without access to these other building and behavior data. Specifically, the forecasting problem is formulated as a quadratic programming problem and solved using the so-called support vector machine (SVM) technique in an online setting. The parameters of the SVM technique are optimized using simulated annealing approach. The proposed approach is applied to hourly smart meters data for several residential customers over several days.« less

1997-12-31

The success of market approaches to pollution control in reducing the cost of compliance with environmental regulation, has insured the inclusion of emissions trading programs in current and future regulatory programs. As these environmental trading programs multiply, (SO{sub 2}, NO{sub x}, Ozone Precursors, Wetlands, CO{sub 2} and others), utility companies will need a central location to buy, sell, and trade these allowances to meet regulatory needs. In response, SAIC has designed and prototyped an electronic trading system that can provide a common forum for the location and exchange of environmental allowances, marketable permits, and other market based instruments for environmentalmore » management. SAIC intends to open and operate the Allowance Exchange (ALEX) for the trading of all environmental allowances, associated with the operation of electric utilities, as a service to the nation, the industry, and the environmental community.« less
