The impact of teacher preparation on student achievement in rural secondary schools

NASA Astrophysics Data System (ADS)

Barnes, Shontier Prescott

The primary purpose of this study was to examine significant differences, if any, in student achievement in the area of math and science of students taught by traditionally certified teachers and alternatively certified teachers. This study examined alternatively certified teachers, as identified from through the Georgia TAPP (Teacher Alternative Preparation Program), and traditionally certified teachers in rural high schools in the Central Savannah River Area of Georgia. Student achievement was measured by student scores on the Algebra I and Physical Science End-Of-Course Test, a criterion-referenced test aligned with state adopted curriculum standards. The study utilized frequency distributions, correlations, descriptive statistics, and univariate analysis of variance (ANOVA) to examine the data. Univariate tests were done to find individual differences for each dependent variable. The ANOVA was used for the single dependent (student achievement) and formed comparisons and tracked the effect of the independent variable (teacher preparation), each of which (traditional and alternative) may have a number of levels and may interact to affect the dependent variable. The covariates, the independent variables not manipulated, but still affecting the response, are students' ethnicity, gender, and school socioeconomic status were also analyzed to predict student achievement. KEY WORDS. Teacher Preparation, Student Achievement, Math, Science, Traditionally certified teachers, Alternatively certified teachers, Georgia TAPP (Teacher Alternative Preparation Program), End-Of-Course Test (EOCT), Performance standard.

Implicit and explicit attitudes towards conventional and complementary and alternative medicine treatments: Introduction of an Implicit Association Test.

PubMed

Green, James A; Hohmann, Cynthia; Lister, Kelsi; Albertyn, Riani; Bradshaw, Renee; Johnson, Christine

2016-06-01

This study examined associations between anticipated future health behaviour and participants' attitudes. Three Implicit Association Tests were developed to assess safety, efficacy and overall attitude. They were used to examine preference associations between conventional versus complementary and alternative medicine among 186 participants. A structural equation model suggested only a single implicit association, rather than three separate domains. However, this single implicit association predicted additional variance in anticipated future use of complementary and alternative medicine beyond explicit. Implicit measures should give further insight into motivation for complementary and alternative medicine use. © The Author(s) 2014.

Health need and the use of alternative medicine among adults who do not use conventional medicine

PubMed Central

2010-01-01

Background We hypothesize that a substantial portion of individuals who forgo conventional care in a given year turn to some form of alternative medicine. This study also examines whether individuals who use only alternative medicine will differ substantially in health and sociodemographic status from individuals using neither alternative medicine nor conventional care in a given year. To identify those factors that predict alternative medicine use in those not using conventional care, we employed the socio-behavioral model of healthcare utilization. Methods The current study is a cross-sectional regression analysis using data from the 2002 National Health Interview Survey. Data were collected in-person from 31,044 adults throughout the 50 states and the District of Columbia. Results 19.3% of adults (38.3 million) did not use conventional care in a 12 month period, although 39.5% of these individuals (14.7 million) reported having one or more problems with their health. Of those not using conventional care, 24.8% (9.5 million) used alternative medicine. Users of alternative medicine had more health needs and were more likely to delay conventional care because of both cost and non-cost factors compared to those not using alternative medicine. While individual predisposing factors (gender, education) were positively associated with alternative medicine use, enabling factors (poverty status, insurance coverage) were not. Conclusions We found that a quarter of individuals who forgo conventional care in a given year turn towards alternative medicine. Our study suggests that the potential determinants of using only alternative medicine are multifactorial. Future research is needed to examine the decision process behind an individual's choice to use alternative medicine but not conventional medicine and the clinical outcomes of this choice.

Testing Alternative Definitions of Chronic Homelessness.

PubMed

Byrne, Thomas; Culhane, Dennis P

2015-09-01

This study examined the potential impact of a proposed change to the official federal definition of chronic homelessness. Using administrative data from the emergency shelters in a large U.S. city, this study estimated the number of persons identified as chronically homeless under the current definition of chronic homelessness, a proposed new federal definition, and two alternative definitions and examined shelter utilization for each group. Fewer than half as many people were considered chronically homeless under the proposed new federal definition compared with the current definition. Persons considered chronically homeless by the proposed new definition and, to a lesser extent, by the two alternative definitions, made heavier use of shelter compared with persons who met the current definition. A proposed new and two alternative definitions of chronic homelessness are better suited than the existing federal definition for identifying persons with the most protracted experiences of homelessness.

Alternative Physics Examination Questions: Identification and Explanation of Different Discriminating Powers

NASA Astrophysics Data System (ADS)

Forster, Patricia A.

2005-12-01

The issue of unfairness arises in high-stakes public examinations when students choose questions from alternatives that are offered and marks on the alternatives turn out to be discrepant. This paper addresses and defines unfairness and discrepancy in the context of alternative questions in Physics Tertiary Entrance Examinations (TEE) in Western Australia. As well, I present an analysis of question characteristics that explain observed marks-differences. The characteristics mainly relate to the construction of the text of questions, the detail on diagrams, and requirements for calculation. The list of characteristics could inform the setting of compulsory as well as alternative examination questions. The paper includes a brief exploration of results by gender on the alternative Physics TEE questions.

Couple Identity, Sacrifice, and Availability of Alternative Partners: Dedication in Friends With Benefits Relationships.

PubMed

Owen, Jesse; Fincham, Frank D; Polser, Geneva

2017-08-01

Friends with benefit relationships (FWB) combine elements of ongoing friendship and physical intimacy. Although many studies have examined predictors of who are likely to enter these relationships as well as their outcomes, we do not know what relational factors are associated with FWB relationship outcomes. This study examined the association between three commitment variables: couple identity, satisfaction with sacrifice, and alternative availability and FWB relationship adjustment and sexual satisfaction. In a young adult sample (n = 171), bivariate correlations demonstrated greater couple identity, more satisfaction with sacrifice, and less alternative availability which were associated with greater relationship adjustment, but not sexual satisfaction. In a multivariate context, satisfaction with sacrifice was the only significant predictor of FWB relationship adjustment. There was also a significant interaction between alternative availability and satisfaction with sacrifice in the prediction of sexual satisfaction. For those who perceived fewer alternative options, the degree to which they were satisfied with sacrificing for their partner was positively associated with sexual satisfaction. Implications for enhancing FWB relationships are discussed.

Alternatives to Testosterone Therapy: A Review.

PubMed

Lo, Eric M; Rodriguez, Katherine M; Pastuszak, Alexander W; Khera, Mohit

2018-01-01

Although testosterone therapy (TTh) is an effective treatment for hypogonadism, recent concerns regarding its safety have been raised. In 2015, the US Food and Drug Administration issued a warning about potential cardiovascular risks resulting from TTh. Fertility preservation is another reason to search for viable alternative therapies to conventional TTh, and in this review we evaluate the literature examining these alternatives. To review the role and limitations of non-testosterone treatments for hypogonadism. A literature search was conducted using PubMed to identify relevant studies examining medical and non-medical alternatives to TTh. Search terms included hypogonadism, testosterone replacement therapy, testosterone therapy, testosterone replacement alternatives, diet and exercise and testosterone, varicocele repair and testosterone, stress reduction and testosterone, and sleep apnea and testosterone. Review of peer-reviewed literature. Medical therapies examined include human chorionic gonadotropins, aromatase inhibitors, and selective estrogen receptor modulators. Non-drug therapies that are reviewed include lifestyle modifications including diet and exercise, improvements in sleep, decreasing stress, and varicocele repair. The high prevalence of obesity and metabolic syndrome in the United States suggests that disease modification could represent a viable treatment approach for affected men with hypogonadism. These alternatives to TTh can increase testosterone levels and should be considered before TTh. Lo EM, Rodriguez KM, Pastuszak AW, Khera M. Alternatives to Testosterone Therapy: A Review.

Self-Uncertainty and the Influence of Alternative Goals on Self-Regulation.

PubMed

Light, Alysson E; Rios, Kimberly; DeMarree, Kenneth G

2018-01-01

The current research examines factors that facilitate or undermine goal pursuit. Past research indicates that attempts to reduce self-uncertainty can result in increased goal motivation. We explore a critical boundary condition of this effect-the presence of alternative goals. Though self-regulatory processes usually keep interest in alternative goals in check, uncertainty reduction may undermine these self-regulatory efforts by (a) reducing conflict monitoring and (b) increasing valuation of alternative goals. As such, reminders of alternative goals will draw effort away from focal goals for self-uncertain (but not self-certain) participants. Across four studies and eight supplemental studies, using different focal goals (e.g., academic achievement, healthy eating) and alternative goals (e.g., social/emotional goals, attractiveness, indulgence), we found that alternative goal salience does not negatively influence goal-directed behavior among participants primed with self-certainty, but that reminders of alternative goals undermine goal pursuit among participants primed with self-uncertainty.

Alternative models of DSM-5 PTSD: Examining diagnostic implications.

PubMed

Murphy, Siobhan; Hansen, Maj; Elklit, Ask; Yong Chen, Yoke; Raudzah Ghazali, Siti; Shevlin, Mark

2018-04-01

The factor structure of DSM-5 posttraumatic stress disorder (PTSD) has been extensively debated with evidence supporting the recently proposed seven-factor Hybrid model. However, despite myriad studies examining PTSD symptom structure few have assessed the diagnostic implications of these proposed models. This study aimed to generate PTSD prevalence estimates derived from the 7 alternative factor models and assess whether pre-established risk factors associated with PTSD (e.g., transportation accidents and sexual victimisation) produce consistent risk estimates. Seven alternative models were estimated within a confirmatory factor analytic framework using the PTSD Checklist for DSM-5 (PCL-5). Data were analysed from a Malaysian adolescent community sample (n = 481) of which 61.7% were female, with a mean age of 17.03 years. The results indicated that all models provided satisfactory model fit with statistical superiority for the Externalising Behaviours and seven-factor Hybrid models. The PTSD prevalence estimates varied substantially ranging from 21.8% for the DSM-5 model to 10.0% for the Hybrid model. Estimates of risk associated with PTSD were inconsistent across the alternative models, with substantial variation emerging for sexual victimisation. These findings have important implications for research and practice and highlight that more research attention is needed to examine the diagnostic implications emerging from the alternative models of PTSD.

2015-01-01

The aim of this study was to investigate the usefulness of postmortem external examination performed by an experienced clinical geneticist as an alternative to autopsy in countries with limited resources. We studied a consecutive cohort of couples seeking genetic counseling for fetal loss or perinatal death over a period of 3 years. The study involved 230 couples; only 57 of them submitted a fetus or dead neonate, for whom a meticulous postmortem clinical examination was performed by an experienced clinical geneticist. The diagnosis rate for the group of cases subjected to postmortem examination (57.9%) was much higher than that of the group that comprised cases for which diagnosis was made through evaluation of medical records (27.2%). Whenever fetal or neonatal autopsy is refused or is not feasible, a comprehensive fetal or perinatal postmortem external examination by an experienced clinical geneticist may be a reasonable substitute.

Complementary and alternative medicine is a broad field of health including all health care practices and methods; and their accompanying theories and beliefs. In the present study, we aimed to examine the frequency of complementary-alternative medicine use, and its relation with glomerular filtration rate and depression in patients with chronic kidney disease at predialysis stage. A total of 1053 predialysis patients; 518 female and 535 male, that were followed up with chronic kidney disease for at least 3 months were enrolled into the study. Demographic features, biochemical parameters and findings of physical examination were recorded. Their compliance to diet, and knowledge about disease were questioned. Beck depression inventory and questionnaire regarding to complementary-alternative medicine use were performed. The overall frequency of complementary-alternative medicine use was 40.3% . Total ratio of herbal products was 46%. Complementary-alternative medicine use was significantly more frequent in female or single patients, and patients that informed about chronic kidney disease or under strict diet (p:0.007, p:0.016, p:0.02, p:0.016; respectively). When glomerular filtration rate of participants were considered, complementary-alternative medicine use was similar in different stages of kidney disease. Depression was observed in 41.9% of patients and significantly frequent in patients with alternative method use (p:0.002). Depression score was higher as creatinine increases and glomerular filtration rate decreases (p:0.002; r: 0,093). We determined that complementary-alternative medicine use gradually increases at predialysis stage as glomerular filtration rate decreases and there is a strict relation between complementary-alternative medicine use and depression or female gender. Disorder related stressors may lead to seeking of alternative methods. This article is protected by copyright. All rights reserved.

Unhappiness Intensifies the Avoidance of Frequent Losses While Happiness Overcomes It.

PubMed

Yechiam, Eldad; Telpaz, Ariel; Krupenia, Stas; Rafaeli, Anat

2016-01-01

The implication of spontaneous and induced unhappiness to people's decision style is examined. It is postulated that unhappy individuals have a greater tendency to avoid frequent losses because these can have depleting effects, and unhappy individuals are more sensitive to such effects. This is evaluated in Study 1 by using an annoying customer call manipulation to induce negative affect; and by examining the effect of this manipulation on choices in an experiential decision task (the Iowa Gambling task). In Study 2 we examined the association between self-reported (un)happiness and choices on the same decision task. In Study 1 the induction of negative affect led to avoidance of choice alternatives with frequent losses, compared to those yielding rarer but larger losses. Specifically, this pertained to the advantageous alternatives with frequent vs. non-frequent losses. In Study 2 unhappiness was similarly associated with less exposure to frequent losses; while extreme high happiness was associated with no tendency to avoid frequent losses when these were part of an advantageous alternative. The findings clarify the role of happiness in decision making processes by indicating that unhappiness induces sensitivity to the frequency rather than to the total effect of negative events.

Diverse alternative back-splicing and alternative splicing landscape of circular RNAs

PubMed Central

Zhang, Xiao-Ou; Dong, Rui; Zhang, Yang; Zhang, Jia-Lin; Luo, Zheng; Zhang, Jun; Chen, Ling-Ling; Yang, Li

2016-01-01

Circular RNAs (circRNAs) derived from back-spliced exons have been widely identified as being co-expressed with their linear counterparts. A single gene locus can produce multiple circRNAs through alternative back-splice site selection and/or alternative splice site selection; however, a detailed map of alternative back-splicing/splicing in circRNAs is lacking. Here, with the upgraded CIRCexplorer2 pipeline, we systematically annotated different types of alternative back-splicing and alternative splicing events in circRNAs from various cell lines. Compared with their linear cognate RNAs, circRNAs exhibited distinct patterns of alternative back-splicing and alternative splicing. Alternative back-splice site selection was correlated with the competition of putative RNA pairs across introns that bracket alternative back-splice sites. In addition, all four basic types of alternative splicing that have been identified in the (linear) mRNA process were found within circRNAs, and many exons were predominantly spliced in circRNAs. Unexpectedly, thousands of previously unannotated exons were detected in circRNAs from the examined cell lines. Although these novel exons had similar splice site strength, they were much less conserved than known exons in sequences. Finally, both alternative back-splicing and circRNA-predominant alternative splicing were highly diverse among the examined cell lines. All of the identified alternative back-splicing and alternative splicing in circRNAs are available in the CIRCpedia database (http://www.picb.ac.cn/rnomics/circpedia). Collectively, the annotation of alternative back-splicing and alternative splicing in circRNAs provides a valuable resource for depicting the complexity of circRNA biogenesis and for studying the potential functions of circRNAs in different cells.

Technical and economic feasibility of alternative fuel use in process heaters and small boilers

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

Not Available

1980-02-01

The technical and economic feasibility of using alternate fuels - fuels other than oil and natural gas - in combustors not regulated by the Powerplant and Industrial Fuel Use Act of 1978 (FUA) was evaluated. FUA requires coal or alternate fuel use in most large new boilers and in some existing boilers. Section 747 of FUA authorizes a study of the potential for reduced oil and gas use in combustors not subject to the act: small industrial boilers with capacities less than 100 MMBtu/hr, and process heat applications. Alternative fuel use in combustors not regulated by FUA was examined andmore » the impact of several measures to encourage the substitution of alternative fuels in these combustors was analyzed. The primary processes in which significant fuel savings can be achieved are identified. Since feedstock uses of oil and natural gas are considered raw materials, not fuels, feedstock applications are not examined in this analysis. The combustors evaluated in this study comprise approximately 45% of the fuel demand projected in 1990. These uses would account for more than 3.5 million barrels per day equivalent fuel demand in 1990.« less

Evidence that "brain-specific" FOX-1, FOX-2, and nPTB alternatively spliced isoforms are produced in the lens.

PubMed

Bitel, Claudine L; Nathan, Rachel; Wong, Patrick; Kuppasani, Sunil; Matsushita, Masafumi; Kanazawa, Hrioshi; Frederikse, Peter H

2011-04-01

Alternative RNA splicing is essential in development and more rapid physiological processes that include disease mechanisms. Studies over the last 20 years demonstrated that RNA binding protein families, which mediate the alternative splicing of a large percentage of genes in mammals, contain isoforms with mutually exclusive expression in non-neural and neural progenitor cells vs. post-mitotic neurons, and regulate the comprehensive reprogramming of alternative splicing during neurogenesis. Polypyrimidine tract binding (PTB) proteins and Fox-1 proteins also undergo mutually exclusive alternative splicing in neural and non-neural cells that regulates their tissue-specific expression and splicing activities. Over the past 50 years, striking morphological similarities noted between lens fiber cells and neurons suggested that cell biology processes and gene expression profiles may be shared as well. Here, we examined mouse and rat lenses to determine if alternative splicing of neuronal nPTB and Fox-1/Fox-2 isoforms also occurs in lenses. Immunoblot, immunofluorescence, and RT-PCR were used to examine expression and alternative splicing of transcripts in lens and brain. We demonstrated that exon 10 is predominantly included in nPTB transcripts consistent with nPTB protein in lenses, and that alternatively spliced Fox-1/-2 lens transcripts contain exons that have been considered neuron-specific. We identified a 3' alternative Fox-1 exon in lenses that encodes a nuclear localization signal consistent with its protein distribution detected in fiber cells. Neuronal alternative splicing of kinesin KIF1Bβ2 has been associated with PTB/nPTB and Fox-2, and we found that two 'neuron-specific' exons are also included in lenses. The present study provides evidence that alternative neuronal nPTB and Fox-1/Fox-2 isoforms are also produced in lenses. These findings raise questions regarding the extent these factors contribute to a similar reprogramming of alternative splicing during lens differentiation, and the degree that alternative gene transcripts produced during neurogenesis are also expressed in the lens.

Alternative splicing and nonsense-mediated decay of circadian clock genes under environmental stress conditions in Arabidopsis

PubMed Central

2014-01-01

Background The circadian clock enables living organisms to anticipate recurring daily and seasonal fluctuations in their growth habitats and synchronize their biology to the environmental cycle. The plant circadian clock consists of multiple transcription-translation feedback loops that are entrained by environmental signals, such as light and temperature. In recent years, alternative splicing emerges as an important molecular mechanism that modulates the clock function in plants. Several clock genes are known to undergo alternative splicing in response to changes in environmental conditions, suggesting that the clock function is intimately associated with environmental responses via the alternative splicing of the clock genes. However, the alternative splicing events of the clock genes have not been studied at the molecular level. Results We systematically examined whether major clock genes undergo alternative splicing under various environmental conditions in Arabidopsis. We also investigated the fates of the RNA splice variants of the clock genes. It was found that the clock genes, including EARLY FLOWERING 3 (ELF3) and ZEITLUPE (ZTL) that have not been studied in terms of alternative splicing, undergo extensive alternative splicing through diverse modes of splicing events, such as intron retention, exon skipping, and selection of alternative 5′ splice site. Their alternative splicing patterns were differentially influenced by changes in photoperiod, temperature extremes, and salt stress. Notably, the RNA splice variants of TIMING OF CAB EXPRESSION 1 (TOC1) and ELF3 were degraded through the nonsense-mediated decay (NMD) pathway, whereas those of other clock genes were insensitive to NMD. Conclusion Taken together, our observations demonstrate that the major clock genes examined undergo extensive alternative splicing under various environmental conditions, suggesting that alternative splicing is a molecular scheme that underlies the linkage between the clock and environmental stress adaptation in plants. It is also envisioned that alternative splicing of the clock genes plays more complex roles than previously expected. PMID:24885185

Renewal, Resurgence, and Alternative Reinforcement Context

PubMed Central

Sweeney, Mary M.; Shahan, Timothy A.

2015-01-01

Resurgence, relapse induced by the removal of alternative reinforcement, and renewal, relapse induced by a change in contextual stimuli, are typically studied separately in operant conditioning paradigms. In analogous treatments of operant problem behavior, aspects of both relapse phenomena can operate simultaneously. Therefore, the purpose of this study was to examine a novel method for studying resurgence and renewal in the same experimental preparation. An alternative source of reinforcement was available during extinction for one group of rats (a typical resurgence preparation). Another group experienced an operant renewal preparation in which the extinction context was distinguished via olfactory and visual stimuli. A third group experienced alternative reinforcement delivery in the new context, a novel combination of typical resurgence and renewal preparations. Removal of alternative reinforcement and/or a change in context induced relapse, relative to an extinction-only control group. When alternative reinforcement was delivered in a novel context, the alternative response was less persistent relative to when extinction of the alternative response took place in the context in which it was trained. This methodology might be used to illustrate shared (or distinct) mechanisms of resurgence and renewal, and to determine how delivering alternative reinforcement in another context may affect persistence and relapse.

Bates, R.; Cofala, J.; Toman, M.

1994-01-01

Like other Central European countries, Poland faces the twin challenges of improving environmental quality while also promoting economic development. The study examines the cost of achieving alternative emission standards and the savings in abatement cost that might be achieved with policies that rely on economic incentives rather than with rigid command and control measures. A central element of the analysis is a dynamic model of least-cost energy supply in Poland that allows examination at a national level of the effects of different pollution standards and policies.

Alternation blindness in the representation of binary sequences.

PubMed

Yu, Ru Qi; Osherson, Daniel; Zhao, Jiaying

2018-03-01

Binary information is prevalent in the environment and contains 2 distinct outcomes. Binary sequences consist of a mixture of alternation and repetition. Understanding how people perceive such sequences would contribute to a general theory of information processing. In this study, we examined how people process alternation and repetition in binary sequences. Across 4 paradigms involving estimation, working memory, change detection, and visual search, we found that the number of alternations is underestimated compared with repetitions (Experiment 1). Moreover, recall for binary sequences deteriorates as the sequence alternates more (Experiment 2). Changes in bits are also harder to detect as the sequence alternates more (Experiment 3). Finally, visual targets superimposed on bits of a binary sequence take longer to process as alternation increases (Experiment 4). Overall, our results indicate that compared with repetition, alternation in a binary sequence is less salient in the sense of requiring more attention for successful encoding. The current study thus reveals the cognitive constraints in the representation of alternation and provides a new explanation for the overalternation bias in randomness perception.

Influence of sedentary, social, and physical alternatives on food reinforcement.

PubMed

Carr, Katelyn A; Epstein, Leonard H

2018-02-01

This study examined the potential for nonfood alternative activities to compete with the reinforcing value of food. Participants rated the frequency and pleasantness of engaging in a variety of activities and made hypothetical choices between food and 4 types of alternatives; cognitive-enriching (reading, listening to music), social (attending a party or event), sedentary (watching TV), and physically active (running, biking). Two-hundred seventy-six adults completed an online survey using a crowdsourcing platform. Adults with higher BMI reported engaging in fewer activities within the cognitive-enriching, social, and physically active categories. When examining how well each alternative activity type was able to compete with food, sedentary alternatives were associated with the highest food reinforcement, or were least able to compete with food reinforcers, as compared with cognitive-enriching, social, and physical. Social activities were associated with the lowest food reinforcement, or the best able to compete with food reinforcers. These results suggest that increasing the frequency and range of nonfood alternative activities may be important to obesity. This study also suggests that the class of social activities may have the biggest impact on reducing food reinforcement, and the class of sedentary may have the smallest effect on food reinforcement. These tools have relevance to clinical interventions that capitalize on increasing access to behaviors that can reduce the motivation to eat in clinical interventions for obesity.

Moving virtuality into reality: A comparison study of the effectiveness of traditional and alternative assessments of learning in a multisensory, fully immersive physics program

NASA Astrophysics Data System (ADS)

Gamor, Keysha Ingram

This paper contains a research study that investigated the relative efficacy of using both a traditional paper-and-pencil assessment instrument and an alternative, virtual reality (VR) assessment instrument to assist educators and/or instructional designers in measuring learning in a virtual reality learning environment. To this end, this research study investigated assessment in VR, with the goal of analyzing aspects of student learning in VR that are feasible to access or capture by traditional assessments and alternative assessments. The researcher also examined what additional types of learning alternative assessments may offer. More specifically, this study compared the effectiveness of a traditional method with an alternative (performance-based) method of assessment that was used to examine the ability of the tools to accurately evidence the levels of students' understanding and learning. The domain area was electrostatics, a complex, abstract multidimensional concept, with which students often experience difficulty. Outcomes of the study suggest that, in the evaluation of learning in an immersive VR learning environment, assessments would most accurately manifest student learning if the assessment measure matched the learning environment itself. In this study, learning and assessing in the VR environment yielded higher final test scores than learning in VR and testing with traditional paper-and-pencil. Being able to transfer knowledge from a VR environment to other situations is critical in demonstrating the overall level of understanding of a concept. For this reason, the researcher recommends a combination of testing measures to enhance understanding of complex, abstract concepts.

What Undergraduates Misunderstand about Stem Cell Research

Halverson, Kristy Lynn; Freyermuth, Sharyn K.; Siegel, Marcelle A.; Clark, Catharine G.

2010-11-01

As biotechnology-related scientific advances, such as stem cell research (SCR), are increasingly permeating the popular media, it has become ever more important to understand students' ideas about this issue. Very few studies have investigated learners' ideas about biotechnology. Our study was designed to understand the types of alternative conceptions students hold concerning SCR. The qualitative research design allowed us to examine college students' understandings about stem cells and SCR. More specifically, we addressed the following questions: How can alternative conceptions about stem cell topics be categorized? What types of alternative conceptions are most common? Participants included 132 students enrolled in a biotechnology course that focused on the scientific background of biotechnology applications relevant to citizens. In this study, we used an inductive approach to develop a taxonomy of alternative ideas about SCR by analyzing student responses to multiple open-ended data sources. We identified five categories of conceptions: alternative conceptions about what, alternative conceptions about how, alternative conceptions about medical potential, terminology confusion, and political and legal alternative conceptions. In order to improve instruction, it is important to understand students' ideas when entering the classroom. Our findings highlight a need to teach how science can be applied to societal issues and improve science literacy and citizenship.

Influence of energy alternatives and carbon emissions on an institution's green reputation.

PubMed

Komarek, Timothy M; Lupi, Frank; Kaplowitz, Michael D; Thorp, Laurie

2013-10-15

Institutions' reputation for being environmentally friendly or 'green' can come from many sources. This paper examines how the attributes of alternative energy management plans impact an institutions' 'green' reputation by focusing on the interaction between 'external' and 'internal' influences. Some 'external' influences on environmental reputation we studied include the institution's mix of fuels, energy conservation effort, carbon emissions targets, investment time-frame, and program cost. The 'internal' influences on institutions' green reputation we examined include altruism (respondents' concern for the welfare of others) and environmentalism (respondents' concern for the environment). Using a stated-preference conjoint survey, we empirically examine how attributes of alternative energy management plans influence a large, research university's 'green' reputation. Our results show that constituents benefit from their institution's green reputation and that the energy management choices of the institution can significantly influence its perceived green reputation. Furthermore, integrating internal and external influences on reputation can create more informative models and better decision-making. Copyright © 2013 Elsevier Ltd. All rights reserved.

Positive attitudes toward organic, local, and sustainable foods are associated with higher dietary quality among young adults

PubMed Central

Laska, Melissa N.; Neumark-Sztainer, Dianne; Story, Mary

2012-01-01

Scant evidence is available on the relationship between preferences for organic, local, sustainable, and non-processed foods (i.e., alternative food production practices) and dietary quality. This cross-sectional study examined the characteristics and dietary behaviors (e.g., consumption of fruit, vegetables, fast food, etc.) of young adults who reported placing low, moderate, or high importance on alternative food production practices. A diverse sample of 1,201 students at a two-year community college and a four-year public university in the Twin Cities, MN, completed the Student Health and Wellness Study survey in spring 2010. Chi-square tests examined differences in attitudes across demographic characteristics. Linear regression adjusted dietary intake across attitudes. About half (49%) of young adults placed moderate to high importance on alternative production practices, and few demographic differences across attitudes were found. Young adults who placed high importance on alternative production practices consumed 1.3 greater servings of fruits and vegetables (p<0.001), more dietary fiber (p<0.001), fewer added sugars (p<0.001) and less fat (p=0.025) than those who placed low importance on these practices. Young adults who placed high importance on alternative food production practices also consumed breakfast about one more day per week and fast food half as often as those who placed low importance on these practices (p<0.001). Study findings suggest that nutrition messaging around social and environmental implications of food production practices may be well received by this age group. Experimental studies are needed to investigate whether attitudes toward alternative production practices can be manipulated to improve dietary quality. PMID:23260729

Resurgence and alternative-reinforcer magnitude.

PubMed

Craig, Andrew R; Browning, Kaitlyn O; Nall, Rusty W; Marshall, Ciara M; Shahan, Timothy A

2017-03-01

Resurgence is defined as an increase in the frequency of a previously reinforced target response when an alternative source of reinforcement is suspended. Despite an extensive body of research examining factors that affect resurgence, the effects of alternative-reinforcer magnitude have not been examined. Thus, the present experiments aimed to fill this gap in the literature. In Experiment 1, rats pressed levers for single-pellet reinforcers during Phase 1. In Phase 2, target-lever pressing was extinguished, and alternative-lever pressing produced either five-pellet, one-pellet, or no alternative reinforcement. In Phase 3, alternative reinforcement was suspended to test for resurgence. Five-pellet alternative reinforcement produced faster elimination and greater resurgence of target-lever pressing than one-pellet alternative reinforcement. In Experiment 2, effects of decreasing alternative-reinforcer magnitude on resurgence were examined. Rats pressed levers and pulled chains for six-pellet reinforcers during Phases 1 and 2, respectively. In Phase 3, alternative reinforcement was decreased to three pellets for one group, one pellet for a second group, and suspended altogether for a third group. Shifting from six-pellet to one-pellet alternative reinforcement produced as much resurgence as suspending alternative reinforcement altogether, while shifting from six pellets to three pellets did not produce resurgence. These results suggest that alternative-reinforcer magnitude has effects on elimination and resurgence of target behavior that are similar to those of alternative-reinforcer rate. Thus, both suppression of target behavior during alternative reinforcement and resurgence when conditions of alternative reinforcement are altered may be related to variables that affect the value of the alternative-reinforcement source. © 2017 Society for the Experimental Analysis of Behavior.

CHIP premiums, health status, and the insurance coverage of children.

PubMed

Marton, James; Talbert, Jeffery C

2010-01-01

This study uses the introduction of premiums into Kentucky's Children's Health Insurance Program (KCHIP) to examine whether the enrollment impact of new premiums varies by child health type. We also examine the extent to which children find alternative coverage after premium nonpayment. Public insurance claims data suggest that those with chronic health conditions are less likely to leave public coverage. We find little evidence of a differential impact of premiums on enrollment among the chronically ill. Our survey of nonpayers shows that 56% of responding families found alternative private or public health coverage for their children after losing CHIP.

Examining the job search-turnover relationship: the role of embeddedness, job satisfaction, and available alternatives.

Swider, Brian W; Boswell, Wendy R; Zimmerman, Ryan D

2011-03-01

This study examined factors that may help explain under what conditions employee job search effort may most strongly (or weakly) predict subsequent turnover. As predicted, the job search-turnover relationship was stronger when employees had lower levels of job embeddedness and job satisfaction and higher levels of available alternatives. These findings suggest that there may be a number of factors interacting to influence employees' turnover decisions, indicating greater complexity to the process than described in prominent sequential turnover models.

A 4-year study on the effectiveness of alternate grazing of cattle and sheep in the control of bovine parasitic gastro-enteritis.

Bairden, K; Armour, J; Duncan, J L

1995-11-01

In many farming enterprises, animal management systems which could provide a practical and effective alternative to chemotherapy for the control of bovine helminthosis would be readily accepted. One system which has been proposed and shown to be effective in the short or medium term involves grazing different host species on a rotational basis. The study described here examined the effect of alternating cattle and sheep annually over an extended period of 4 years. Up to the second grazing season the system appeared to be successful, with a marked reduction in the cattle worm burdens. However, by the end of the study period the parasite burdens in calves grazed on the alternated pasture were equal to, or greater than, those of set-stocked control animals. It was thus clear that the alternate grazing strategy had failed. Data obtained from other parameters measured, i.e. faecal egg counts, pasture larval numbers and plasma pepsinogen levels, confirmed this observation.

The psychology of ‘regrettable substitutions’: Examining consumer judgements of Bisphenol A and its alternatives

PubMed Central

Scherer, Laura D.; Maynard, Andrew; Dolinoy, Dana C.; Fagerlin, Angela; Zikmund-Fisher, Brian J.

2018-01-01

Bisphenol A is a chemical used to make certain types of plastics and is found in numerous consumer products. Because scientific studies have raised concerns about Bisphenol A’s potential impact on human health, it has been removed from some (but not all) products. What many consumers do not know, however, is that Bisphenol A is often replaced with other, less-studied chemicals whose health implications are virtually unknown. This type of situation is known as a potential ‘regrettable substitution’, because the substitute material might actually be worse than the material that it replaces. Regrettable substitutions are a common concern among policymakers, and they are a real-world manifestation of the tension that can exist between the desire to avoid risk (known possible consequences that might or might not occur) and ambiguity (second-order uncertainty), which is itself aversive. In this article we examine how people make such trade-offs using the example of Bisphenol A. Using data from Study 1, we show that people have inconsistent preferences toward these alternatives and that choice is largely determined by irrelevant contextual factors such as the order in which the alternatives are evaluated. Using data from Study 2 we further demonstrate that when people are informed of the presence of substitute chemicals, labeling the alternative product as ‘free’ of Bisphenol A causes them to be significantly more likely to choose the alternative despite its ambiguity. We discuss the relevance of these findings for extant psychological theories as well as their implications for risk, policy and health communication. PMID:29386966

Resurgence with and without an alternative response.

PubMed

Kimball, Ryan T; Kelley, Michael E; Podlesnik, Christopher A; Forton, Alex; Hinkle, Brandy

2018-05-10

Resurgence is the reemergence of a previously reinforced response that occurs after the elimination or reduction of reinforcement for an alternative response. Resurgence is problematic in the context of treatment because the reemergence of a previously reinforced destructive response could be detrimental to treatment gains. In the current translational study, we examined a modified resurgence procedure in which the alternative response was either present or absent during extinction. Four participants were exposed to three phases that consisted of (1) reinforcement of a target response, (2) extinction of the target response and differential reinforcement of an alternative response, and (3) extinction of both responses. Results for four out of five assessments showed greater resurgence when the alternative response was absent during Phase 3. Results suggest that more robust resurgence might occur if the alternative response is not available as opposed to the alternative response contacting extinction. © 2018 Society for the Experimental Analysis of Behavior.

Examining the DSM-5 alternative model of personality disorders operationalization of obsessive-compulsive personality disorder in a mental health sample.

PubMed

Liggett, Jacqueline; Sellbom, Martin

2018-06-21

The current study evaluated the continuity between the diagnostic operationalizations of obsessive-compulsive personality disorder (OCPD) in the Diagnostic and Statistical Manual for Mental Disorders, Fifth Edition, both as traditionally operationalized and from the perspective of the alternative model of personality disorders. Using both self-report and informant measures, the study had the following four aims: (a) to examine the extent to which self-report and informant data correspond, (b) to investigate whether both self-report and informant measures of the alternative model of OCPD can predict traditional OCPD, (c) to determine if any traits additional to those proposed in the alternative model of OCPD can predict traditional OCPD, and (d) to investigate whether a measure of OCPD-specific impairment is better at predicting traditional OCPD than are measures of general impairment in personality functioning. A mental health sample of 214 participants was recruited and administered measures of both the traditional and alternative models of OCPD. Self-report data moderately corresponded with informant data, which is consistent with the literature. Results further confirmed rigid perfectionism as the core trait of OCPD. Perseveration and workaholism were also associated with OCPD. Hostility was identified as a trait deserving further research. A measure of OCPD-specific impairment demonstrated its ability to incrementally predict OCPD over general measures of impairment. (PsycINFO Database Record (c) 2018 APA, all rights reserved).

These included helping older persons secure benefits and services, enhancing their financial security, and reducing financial exploitation.

Attitudes towards and personal use of complementary and alternative medicine amongst clinicians working in audiovestibular disciplines.

Crundwell, G; Baguley, D M

2016-08-01

Literature indicates that complementary and alternative medicine is used by patients with auditory and vestibular symptoms. This study sought to determine the prevalence of complementary and alternative medicine uptake, and examine attitudes towards complementary and alternative medicine in clinicians working with audiovestibular disorder patients. The Holistic Complementary and Alternative Medicine Questionnaire and a devised questionnaire about recent and lifetime use of complementary and alternative medicine were used. Fifty-four individuals, including audiologists, ENT surgeons, nurses and rehabilitationists, completed the questionnaires (67 per cent response rate). Lifetime prevalence of complementary and alternative medicine uptake was 44 per cent, and 12-month prevalence was 22 per cent. Uptake was more common in females, but there was no significant difference in use when comparing age, seniority or profession. Attitudes towards complementary and alternative medicine were mildly adverse, but sizeable standard deviation indicates wide-ranging attitudes. Clinicians working with patients with audiovestibular disorders have a range of attitudes towards complementary and alternative medicine. Personal uptake of complementary and alternative medicine was lower than that of the general UK population, but remains sizeable.

2002-01-01

Stenoses of the innominate artery (IA) may affect flow conditions in the carotid arteries. However, alternating flow in ipsilateral anterior cerebral artery (ACA) due to IA stenosis is extremely rare. A 49-year-old woman who was evaluated for symptomatic cerebrovascular disease presented with right latent subclavian and right carotid system steal. Transcranial Doppler examination displayed systolic deceleration wave-forms in the right terminal internal carotid artery and alternating flow in the right ACA. Magnetic resonance angiography demonstrated tight stenosis of the right IA. For a thorough study of the hemodynamic effects of IA stenosis, a combination of duplex and transcranial Doppler examination is required.

Motivational changes in response to blocked goals and foreshortened time: testing alternatives to socioemotional selectivity theory.

PubMed

Fung, Helene H; Carstensen, Laura L

2004-03-01

Socioemotional selectivity theory contends that when people perceive time as limited, they prioritize emotionally meaningful goals. Although empirical support for the theory has been found in several studies, 2 alternative explanations for the pattern of findings remain: (a) emotional goals are pursued by default because nonemotional goals are blocked, and (b) emotional goals are pursued in search of emotional support rather than emotional meaning. This study tested these alternatives by examining social goals in response to blocked goals and foreshortened time. Findings reveal distinct motivational patterns, as reflected in social preferences and self-reported social goals, in response to the 2 types of constraints.

Dimensionality and consequences of employee commitment to supervisors: a two-study examination.

PubMed

Landry, Guylaine; Panaccio, Alexandra; Vandenberghe, Christian

2010-01-01

Research on the 3-component model of organizational commitment--affective, normative, and continuance--has suggested that continuance commitment comprises 2 subcomponents, perceived lack of alternatives and sacrifice (e.g., S. J. Jaros, 1997; G. W. McGee & R. C. Ford, 1987). The authors aimed to extend that research in the context of employees' commitment to their immediate supervisors. Through two studies, they examined the validity and consequences of a 4-factor model of commitment to supervisors including affective, normative, continuance-alternatives, and continuance-sacrifice components. Study 1 (N = 317) revealed that the 4 components of commitment to supervisors were distinguishable from the corresponding components of organizational commitment. Study 2 (N = 240) further showed that the 4 components of commitment to supervisors differentially related to intention to leave the supervisor, supervisor-directed negative affect and emotional exhaustion. The authors discuss the implications of these findings for the management of employee commitment in organizations.

After completing treatment, most patients follow a pre-determined schedule of regular hospital outpatient appointments, which includes clinical examinations, consultations and routine tests. After several years of surveillance, patients are transferred back to primary care. However, there is limited evidence to support the effectiveness and efficiency of this approach. This paper examines the current rationale and evidence base for hospital-based follow-up after treatment for gynaecological cancer. We investigate what alternative models of care have been formally evaluated and what research is currently in progress in Europe, in order to make tentative recommendations for a model of follow-up. The evidence base for traditional hospital based follow-up is limited. Alternative models have been reported for other cancer types but there are few evaluations of alternative approaches for gynaecological cancers. We identified five ongoing European studies; four were focused on endometrial cancer patients and one feasibility study included all gynaecological cancers. Only one study had reached the reporting stage. Alternative models included nurse-led telephone follow-up and comparisons of more intensive versus less intensive regimes. Outcomes included survival, quality of life, psychological morbidity, patient satisfaction and cost effectiveness of service. More work is needed on alternative strategies for all gynaecological cancer types. New models will be likely to include risk stratification with early discharge from secondary care for early stage disease with fast track access to specialist services for suspected cancer recurrence or other problems.

The impact of two multiple-choice question formats on the problem-solving strategies used by novices and experts.

PubMed

Coderre, Sylvain P; Harasym, Peter; Mandin, Henry; Fick, Gordon

2004-11-05

Pencil-and-paper examination formats, and specifically the standard, five-option multiple-choice question, have often been questioned as a means for assessing higher-order clinical reasoning or problem solving. This study firstly investigated whether two paper formats with differing number of alternatives (standard five-option and extended-matching questions) can test problem-solving abilities. Secondly, the impact of the alternatives number on psychometrics and problem-solving strategies was examined. Think-aloud protocols were collected to determine the problem-solving strategy used by experts and non-experts in answering Gastroenterology questions, across the two pencil-and-paper formats. The two formats demonstrated equal ability in testing problem-solving abilities, while the number of alternatives did not significantly impact psychometrics or problem-solving strategies utilized. These results support the notion that well-constructed multiple-choice questions can in fact test higher order clinical reasoning. Furthermore, it can be concluded that in testing clinical reasoning, the question stem, or content, remains more important than the number of alternatives.

Psychosocial job factors and biological cardiovascular risk factors in Mexican workers.

PubMed

Garcia-Rojas, Isabel Judith; Choi, BongKyoo; Krause, Niklas

2015-03-01

Psychosocial job factors (PJF) have been implicated in the development of cardiovascular disease. The paucity of data from developing economies including Mexico hampers the development of worksite intervention efforts in those regions. This cross-sectional study of 2,330 Mexican workers assessed PJF (job strain [JS], social support [SS], and job insecurity [JI]) and biological cardiovascular disease risk factors [CVDRF] by questionnaire and on-site physical examinations. Alternative formulations of the JS scales were developed based on factor analysis and literature review. Associations between both traditional and alternative job factor scales with CVDRF were examined in multiple regression models, adjusting for physical workload, and socio-demographic factors. Alternative formulations of the job demand and control scales resulted in substantial changes in effect sizes or statistical significance when compared with the original scales. JS and JI showed hypothesized associations with most CVDRF, but they were inversely associated with diastolic blood pressure and some adiposity measures. SS was mainly protective against CVDRF. Among Mexican workers, alternative PJF scales predicted health outcomes better than traditional scales, and psychosocial stressors were associated with most CVDRF. © 2015 Wiley Periodicals, Inc.

Alternative Energy Science and Policy: Biofuels as a Case Study

NASA Astrophysics Data System (ADS)

Ammous, Saifedean H.

This dissertation studies the science and policy-making of alternative energy using biofuels as a case study, primarily examining the instruments that can be used to alleviate the impacts of climate change and their relative efficacy. Three case studies of policy-making on biofuels in the European Union, United States of America and Brazil are presented and discussed. It is found that these policies have had large unintended negative consequences and that they relied on Lifecycle Analysis studies that had concluded that increased biofuels production can help meet economic, energy and environmental goals. A close examination of these Lifecycle Analysis studies reveals that their results are not conclusive. Instead of continuing to attempt to find answers from Lifecycle Analyses, this study suggests an alternative approach: formulating policy based on recognition of the ignorance of real fuel costs and pollution. Policies to combat climate change are classified into two distinct approaches: policies that place controls on the fuels responsible for emissions and policies that target the pollutants themselves. A mathematical model is constructed to compare these two approaches and address the central question of this study: In light of an ignorance of the cost and pollution impacts of different fuels, are policies targeting the pollutants themselves preferable to policies targeting the fuels? It is concluded that in situations where the cost and pollution functions of a fuel are unknown, subsidies, mandates and caps on the fuel might result in increased or decreased greenhouse gas emissions; on the other hand, a tax or cap on carbon dioxide results in the largest decrease possible of greenhouse gas emissions. Further, controls on greenhouse gases are shown to provide incentives for the development and advancement of cleaner alternative energy options, whereas controls on the fuels are shown to provide equal incentives to the development of cleaner and dirtier alternative fuels. This asymmetry in outcomes---regardless of actual cost functions---is the reason why controls on greenhouse gases are deemed favorable to direct fuel subsidies and mandates.

Children as scientists: Adding, connecting and elaborating ideas on the way to conceptual development

NASA Astrophysics Data System (ADS)

Osmundson, Ellen

In this study, I explored how children develop and construct their ideas and alternative frameworks in science. Prior work in this area suggested that changes from alternative conceptions to understandings that more closely resemble scientists' models do not occur in a sequential, linear fashion, nor are they easily accomplished. By employing a constructivist framework grounded in dynamic systems to look at learning, alternative conceptions were viewed not as ideas that need to be "confronted and replaced" but rather as pieces of an intricate puzzle of understanding that when combined create a more complete, functional, continuous understanding of science. Specifically, the study examined students' understandings and conceptualizations of light as they studied it formally for eight weeks. Understandings were measured through interviews, student-generated concept maps, classroom interactions and by examining student work samples. The central questions guiding the investigation were: What were children's (ages 9 and 10) conceptions of light? Did children's ideas about light develop during their eight week study of it? If so, what was the nature of these changes? Results from the study indicated that children had numerous ideas about light before their formal study of it based on their experiences with the world. As children studied light, they learned about it in the dynamic, synergistic and interactive processes of adding new ideas, connecting ideas to one another and elaborating understandings to arrive at progressively more complex and scientific understandings of light. Alternative conceptions, served as both productive and non-productive resources for learning. Further, alternative conceptions and prior understandings did not disappear as children developed their ideas about light. Rather "old" ideas were used and reused to provide support the gradual process of cognitive development of children's ideas about light. Findings from this study can be used to provide science instruction that is both rich in content and rich in opportunities to experience the recursive and dynamic nature of science learning.

The oral examination is a traditional method for assessing the developing physician's medical knowledge, clinical reasoning and interpersonal skills. The typical oral examination is a face-to-face encounter in which examiners quiz examinees on how they would confront a patient case. The advantage of the oral exam is that the examiner can adapt questions to the examinee's response. The disadvantage is the potential for examiner bias and intimidation. Computer-based virtual simulation technology has been widely used in the gaming industry. We wondered whether virtual simulation could serve as a practical format for delivery of an oral examination. For this project, we compared the attitudes and performance of emergency medicine (EM) residents who took our traditional oral exam to those who took the exam using virtual simulation. EM residents (n=35) were randomized to a traditional oral examination format (n=17) or a simulated virtual examination format (n=18) conducted within an immersive learning environment, Second Life (SL). Proctors scored residents using the American Board of Emergency Medicine oral examination assessment instruments, which included execution of critical actions and ratings on eight competency categories (1-8 scale). Study participants were also surveyed about their oral examination experience. We observed no differences between virtual and traditional groups on critical action scores or scores on eight competency categories. However, we noted moderate effect sizes favoring the Second Life group on the clinical competence score. Examinees from both groups thought that their assessment was realistic, fair, objective, and efficient. Examinees from the virtual group reported a preference for the virtual format and felt that the format was less intimidating. The virtual simulated oral examination was shown to be a feasible alternative to the traditional oral examination format for assessing EM residents. Virtual environments for oral examinations should continue to be explored, particularly since they offer an inexpensive, more comfortable, yet equally rigorous alternative.

Children with Autism Spectrum Disorder (ASD) participate in a variety of treatments, including medication, behavioral, alternative and developmental treatments. Parent adherence to these treatments is crucial for positive child outcomes. The current study: 1) Explored patterns of parent adherence across the full range of treatments that are prescribed to children with ASD and, 2) Examined whether parent demographics, parent treatment attitudes, and child ASD severity contribute to parents' adherence across ASD treatments. Questionnaires were distributed to parents of children with ASD in a southeastern state. Parents (N = 274) were included if they were parenting a child with ASD who was receiving treatment for ASD symptoms. Paired t-tests and multiple linear regression were used to assess the study aims. Adherence to medication treatment was significantly greater than adherence to behavioral, developmental, or alternative treatments (adjusted p-values 0.0006, 0.0030, 0.0006 respectively). Perceived family burden of a treatment was associated with lower adherence to medication, developmental, and alternative treatments. Finally, greater ASD severity was associated with lower adherence to alternative treatments. Overall, the independent variables accounted for more variance in adherence to medication and alternative treatments than in behavioral and developmental treatments. Parents' adherence to ASD treatment differs significantly by treatment type and is influenced by parental perceptions of the burden of treatment on the family. These findings highlight the importance of understanding and addressing the impact of ASD treatment regimens on family life. Copyright © 2015 Elsevier Inc. All rights reserved.

Modeling water demand when households have multiple sources of water

Coulibaly, Lassina; Jakus, Paul M.; Keith, John E.

2014-07-01

A significant portion of the world's population lives in areas where public water delivery systems are unreliable and/or deliver poor quality water. In response, people have developed important alternatives to publicly supplied water. To date, most water demand research has been based on single-equation models for a single source of water, with very few studies that have examined water demand from two sources of water (where all nonpublic system water sources have been aggregated into a single demand). This modeling approach leads to two outcomes. First, the demand models do not capture the full range of alternatives, so the true economic relationship among the alternatives is obscured. Second, and more seriously, economic theory predicts that demand for a good becomes more price-elastic as the number of close substitutes increases. If researchers artificially limit the number of alternatives studied to something less than the true number, the price elasticity estimate may be biased downward. This paper examines water demand in a region with near universal access to piped water, but where system reliability and quality is such that many alternative sources of water exist. In extending the demand analysis to four sources of water, we are able to (i) demonstrate why households choose the water sources they do, (ii) provide a richer description of the demand relationships among sources, and (iii) calculate own-price elasticity estimates that are more elastic than those generally found in the literature.

This study aimed to develop an alternative graduated compression bandage for the treatment of venous leg ulcers. Alternative bandage components were identified and assessed for optimal performance as a graduated multi-layer compression bandage. Subsequently the physical characteristics and clinical efficacy of the optimal bandage combination was prospectively examined. Ten healthy limbs were used to develop the optimal combination and 20 limbs with venous ulceration to compare the physical properties of the two bandage types. Subsequently 42 consecutive ulcerated limbs were prospectively treated to examine the efficacy of the new bandage combination. The new combination produced graduated median (range) sub-bandage pressures (mmHg) as follows: ankle 59 (42-100), calf 36 (27-67) and knee 35 (16-67). Over a seven-day period this combination maintained a comparable level of compression with the Charing Cross system, and achieved an overall healing rate at one year of 88%. The described combination should be brought to the attention of healthcare professionals treating venous ulcers as a possible alternative to other forms of multi-layer graduated compression bandages pending prospective, randomised clinical trials.

Examining the progression and consistency of thermal concepts: a cross-age study

Adadan, Emine; Yavuzkaya, Merve Nur

2018-03-01

This cross-sectional study examined how the progression and consistency of students' understanding of thermal concepts in everyday contexts changes across the grade levels. A total of 656 Turkish students from Grade 8 (age 13-14), Grade 10 (age 15-16), and the first year of college (age 19-20) participated in the study. The data were analysed using statistical procedures (descriptive and inferential). Findings indicated a substantial progression in the students' scientific understanding of thermal concepts across grade levels. In addition, the students' alternative conceptions about thermal concepts generally decreased in frequency across grade levels, but certain alternative conceptions were observed in every grade level to a similar extent. Even though the number of students who consistently used scientific ideas increased across grade levels, the number of students who consistently used non-scientific ideas decreased across grade levels. However, the number of students who used scientific and non-scientific ideas inconsistently generally increased as they progressed in the science curriculum. These findings can be associated with either fragmentation or alternative conceptions that result from the gradual enrichment processes students experience when they try to integrate scientific concepts into their conceptual frameworks.

Fong, Lawrence Hoc Nang; So, Amy Siu Ian; Law, Rob

2016-03-01

Cognitive bias is prevalent among gamblers, especially those with gambling problems. Grounded in the heuristics theories, this study contributes to the literature by examining a cognitive bias triggered by the break streak pattern in the casino setting. We postulate that gamblers tend to bet on the latest outcome when there is a break-streak pattern. Moreover, three determinants of the betting decision under break-streak pattern, including the streak length of the alternative outcome, the frequency of the latest outcome, and gender, were identified and examined in this study. A non-participatory observational study was conducted among the Cussec gamblers in a casino in Macao. An analysis of 1229 bets confirms our postulation, particularly when the streak of the alternative outcome is long, the latest outcome is frequent, and the gamblers are females. The findings provide meaningful implications for casino management and public policymakers regarding the minimization of gambling harm.

Since athletic performance is a most importance trait in horses, most research focused on physiological and physical studies of horse athletic abilities. In contrast, the molecular analysis as well as the regulatory pathway studies remain insufficient for evaluation and prediction of horse athletic abilities. In our previous study, we identified AXL receptor tyrosine kinase ( AXL ) gene which was expressed as alternative spliced isoforms in skeletal muscle during exercise. In the present study, we validated two AXL alternative splicing transcripts (named as AXLa for long form and AXLb for short form) in equine skeletal muscle to gain insight(s) into the role of each alternative transcript during exercise. We validated two isoforms of AXL transcripts in horse tissues by reverse transcriptase polymerase chain reaction (RT-PCR), and then cloned the transcripts to confirm the alternative locus and its sequences. Additionally, we examined the expression patterns of AXLa and AXLb transcripts in horse tissues by quantitative RT-PCR (qRT-PCR). Both of AXLa and AXLb transcripts were expressed in horse skeletal muscle and the expression levels were significantly increased after exercise. The sequencing analysis showed that there was an alternative splicing event at exon 11 between AXLa and AXLb transcripts. 3-dimentional (3D) prediction of the alternative protein structures revealed that the structural distance of the connective region between fibronectin type 3 (FN3) and immunoglobin (Ig) domain was different between two alternative isoforms. It is assumed that the expression patterns of AXLa and AXLb transcripts would be involved in regulation of exercise-induced stress in horse muscle possibly through an NF-κB signaling pathway. Further study is necessary to uncover biological function(s) and significance of the alternative splicing isoforms in race horse skeletal muscle.

Exploring alternative conceptions of teachers and informal educators about selected astronomy concepts

NASA Astrophysics Data System (ADS)

Rutherford, Lori B.

The purpose of this study was to (1) identify alternative conceptions concerning astronomy in groups of formal and informal educators, (2) discover the origins of some of these conceptions and (3) explore how practicing teachers planned to address the need for conceptual change in their students. In response to the first question, a number of alternative conceptions were identified in formal educators, with more for teachers of prekindergarten through third grade than fourth through twelfth grade teachers, and very few alternative conceptions in the informal educators group. In regards to the second research question, a number of origins were indicated: logic, books, elementary school, high school, astronomy classes, self-study and observation. In response to the third question, various practicing teachers used computer programs and modeling in order to address some of the alternative conceptions they noticed in their students. These findings were supported by the literature and theoretical frameworks on which the study was based. The study addressed gaps in the literature concerning alternative conceptions and how they related to Ohio's Academic Content Standards along with nineteen other states. This study also addressed the need for a closer examination of informal educators and how they compare to formal educators in terms of having alternative conceptions. And finally, implications and recommendations were made for practicing educators, materials for practicing educators, teacher education, informal and formal education partnerships, standards modification, research methodology and areas of future research.

Previous research has shown that the first federally funded national tobacco education campaign (Tips) increased calls to the national quitline portal (1-800-QUIT-NOW). Quitlines in 13 states have alternate state-specific telephone numbers. This study examined quitline calls to 1-800-QUIT-NOW in states with and without alternate numbers during the Tips campaign. We used data on calls to 1-800-QUIT-NOW from all US states and the District of Columbia from 2 weeks before to 2 weeks after the 2012 Tips campaign. Similar data were obtained for California's alternate number, 1-800-NO-BUTTS. Multivariate linear models examined whether an interaction existed between Tips exposure, as measured by gross rating points, and presence of an alternate quitline number as well as the effect of Tips on calls to California's 1-800-NO-BUTTS. Having an alternate quitline number did not affect the rate of increase in calls to 1-800-QUIT-NOW, but it was associated with lower absolute numbers of calls to 1-800-QUIT-NOW. On average, states with alternate numbers had 98 fewer calls to 1-800-QUIT-NOW per week in a given area code than those without an alternate number (P < .001). In California, Tips gross rating points were positively correlated with calls to 1-800-QUIT-NOW (b = 38.5, P < .001) and to 1-800-NO-BUTTS (b = 14.1, P < .05). The Tips campaign had the same effect in increasing calls to 1-800-QUIT-NOW in states with and without alternate quitline numbers and had a modest spillover effect on calls to California's alternate number. States may consider the advantages and disadvantages of having alternate quitline numbers given continued national promotions of 1-800-QUIT-NOW. This is the first study that assesses whether the impact of a national tobacco education campaign promoting the national quitline portal number was influenced by the presence of state-specific quitline numbers and whether there was any spillover effect on calls to states' alternate quitline numbers. This study provides important information for states to consider the advantages and disadvantages of maintaining state-specific quitline numbers. © Published by Oxford University Press on behalf of the Society for Research on Nicotine and Tobacco 2016.

2015-05-01

Excessive consumption of sugar-sweetened beverages (SSBs) has become an intractable public health concern worldwide, making investigation of healthy beverage alternatives for SSBs imperative. To summarize the available evidence on the effects of replacing SSBs with beverage alternatives on long-term health outcomes. We systematically retrieved studies from six electronic databases from inception to November 2013. Prospective cohort studies and randomized controlled trials (RCTs) examining the effects of substituting beverage alternatives for SSBs on long-term health outcomes in both children and adults were included. The quality of included studies was assessed using the Scottish Intercollegiate Guidelines Network 50 methodology checklists. Six cohort studies and four RCTs were included in the systematic review with the quality rating ranging from acceptable to high. Evidence from both cohort studies and RCTs showed substitution of SSBs by various beverage alternatives was associated with long-term lower energy intake and lower weight gain. However, evidence was insufficient to draw conclusions regarding the effect of beverage substitution on other health outcomes, and which beverage alternative is the best choice. Although studies on this topic are sparse, the available evidence suggests a potential beneficial effect on body weight outcomes when SSBs are replaced by water or low-calorie beverages. Further studies in this area are warranted to fully understand the long-term health implications of beverage substitutions. Copyright © 2015 Academy of Nutrition and Dietetics.

Srinivasan, P

1996-01-01

OBJECTIVE: To investigate a new approach for query expansion based on retrieval feedback. The first objective in this study was to examine alternative query-expansion methods within the same retrieval-feedback framework. The three alternatives proposed are: expansion on the MeSH query field alone, expansion on the free-text field alone, and expansion on both the MeSH and the free-text fields. The second objective was to gain further understanding of retrieval feedback by examining possible dependencies on relevant documents during the feedback cycle. DESIGN: Comparative study of retrieval effectiveness using the original unexpanded and the alternative expanded user queries on a MEDLINE test collection of 75 queries and 2,334 MEDLINE citations. MEASUREMENTS: Retrieval effectivenesses of the original unexpanded and the alternative expanded queries were compared using 11-point-average precision scores (11-AvgP). These are averages of precision scores obtained at 11 standard recall points. RESULTS: All three expansion strategies significantly improved the original queries in terms of retrieval effectiveness. Expansion on MeSH alone was equivalent to expansion on both MeSH and the free-text fields. Expansion on the free-text field alone improved the queries significantly less than did the other two strategies. The second part of the study indicated that retrieval-feedback-based expansion yields significant performance improvements independent of the availability of relevant documents for feedback information. CONCLUSIONS: Retrieval feedback offers a robust procedure for query expansion that is most effective for MEDLINE when applied to the MeSH field. PMID:8653452

Teaching of evolution in public schools: A cross-cultural examination

NASA Astrophysics Data System (ADS)

Stewart, Joshua M.

The current study sought to examine how the cultural settings of Colorado, United States, and Baden-Wurttemberg, Germany, influenced perspectives, understandings, and acceptance of college students who want to become teachers (i.e., prospective teachers) in regard to the theory of evolution, creationism, and intelligent design with both quantitative and qualitative components. The quantitative sample for the study consisted of 221 German prospective teachers from Baden-Wurttemberg and 231 United States prospective teachers from Colorado. The quantitative component consisted of a 42-item survey with both Likert and true/false items to examine how (1) country of origin, (2) religious participation, and (3) educational background influence students' views and understandings of the theory of evolution and alternative conceptions. Additionally, in a Likert 6-item motivated reasoning task (a theoretical construct), prospective teachers were asked to read and critique arguments supporting and opposing the theory of evolution; differences in how students critiqued arguments were hypothesized to demonstrate biases. For a separate sample from the same locations (8 German and 11 United States students), a qualitative component examined prospective teachers' positions on teaching the theory of evolution in public schools. Prospective teachers were asked to provide support for their position, anticipate opposing arguments, and implications that both positions would have for students. Lastly, prospective teachers were also asked to explain and define the theory of evolution. The current study aided in examining how teachers' perspectives, understandings, and acceptance impacted what was taught in the science classroom. The researcher found that country of origin, religious behavior, and educational background predicted prospective teachers' responses to numerous criterion variables used in the current study. Further, qualitative results expressed major differences between prospective teachers' views regarding the inclusion of evolution or alternative conceptions in public schools, between Colorado and Baden-Wurttemberg. As a potential indicator, findings from the current study may be useful in understanding potential differences between these two countries, in regard to perceptions of the theory of evolution and alternative conceptions. Further, findings from the current study might also inform how these topics might be covered in educational settings with a lowered risk of conflict.

Development of Proportional Reasoning: Where Young Children Go Wrong

PubMed Central

Boyer, Ty W.; Levine, Susan C.; Huttenlocher, Janellen

2008-01-01

Previous studies have found that children have difficulty solving proportional reasoning problems involving discrete units until 10- to 12-years of age, but can solve parallel problems involving continuous quantities by 6-years of age. The present studies examine where children go wrong in processing proportions that involve discrete quantities. A computerized proportional equivalence choice task was administered to kindergartners through fourth-graders in Study 1, and to first- and third-graders in Study 2. Both studies involved four between-subjects conditions that were formed by pairing continuous and discrete target proportions with continuous and discrete choice alternatives. In Study 1, target and choice alternatives were presented simultaneously and in Study 2 target and choice alternatives were presented sequentially. In both studies, children performed significantly worse when both the target and choice alternatives were represented with discrete quantities than when either or both of the proportions involved continuous quantities. Taken together, these findings indicate that children go astray on proportional reasoning problems involving discrete units only when a numerical match is possible, suggesting that their difficulty is due to an overextension of numerical equivalence concepts to proportional equivalence problems.

Does motivation for goal pursuit predict how individuals will respond when confronted with unattainable goals? Two studies examined the role of autonomous and controlled motives when pursuing an unattainable goal without (Study 1) or with (Study 2) the opportunity to reengage in alternative goal pursuit. Autonomous motives positively predicted the cognitive ease of reengagement with an alternative goal when the current goal was perceived as unattainable, especially when participants realized goal unattainability relatively early during goal striving. Autonomous motives, however, were negative predictors of cognitive ease of disengagement from an unattainable goal. When faced with failure, autonomously motivated individuals are better off realizing early the goal unattainability. Otherwise, they will find it difficult to disengage cognitively from the pursued goal (despite reengaging cognitively in an alternative goal), possibly due to interfering rumination. PMID:25104918

Markovits, Henry; Lortie-Forgues, Hugues

2011-01-01

Abstract reasoning is critical for science and mathematics, but is very difficult. In 3 studies, the hypothesis that alternatives generation required for conditional reasoning with false premises facilitates abstract reasoning is examined. Study 1 (n = 372) found that reasoning with false premises improved abstract reasoning in 12- to 15-year-olds. Study 2 (n = 366) found a positive effect of simply generating alternatives, but only in 19-year-olds. Study 3 (n = 92) found that 9- to 11-year-olds were able to respond logically with false premises, whereas no such ability was observed in 6- to 7-year-olds. Reasoning with false premises was found to improve reasoning with semiabstract premises in the older children. These results support the idea that alternatives generation with false premises facilitates abstract reasoning. © 2011 The Authors.

2013-01-01

Purpose To compare the repeatability of the alternate cover test between experienced and inexperienced examiners and the effects of dissociation time and examiner bias. Methods Two sites each had an experienced examiner train 10 subjects (inexperienced examiners) to perform short and long dissociation time alternate cover test protocols at near. Each site conducted testing sessions with an examiner triad (experienced examiner and two inexperienced examiners) who were masked to each other’s results. Each triad performed the alternate cover test on 24 patients using both dissociation protocols. In an attempt to introduce bias, each of the paired inexperienced examiners was given a different graph of phoria distribution for the general population. Analysis techniques that adjust for correlations introduced when multiple measurements are obtained on the same patient were used to investigate the effect of examiner and dissociation time on each outcome. Results The range of measured deviations spanned 27.5 prism diopters (Δ) base-in to 17.5Δ base-out. The absolute mean difference between experienced and inexperienced examiners was 2.28 ± 2.4Δ and at least 60% of differences were ≤2Δ. Larger deviations were measured with the long dissociation protocol for both experienced and inexperienced examiners (mean difference range = 1.17 to 2.14Δ, p < 0.0001). The percentage of measured small deviations (2Δ base-out to 2Δ base-in) did not differ between inexperienced examiners biased with the narrow vs. wide theoretical distributions (p = 0.41). The magnitude and direction of the deviation had no effect on the size of the differences obtained with different examiners or dissociation times. Conclusions Although inexperienced examiners differed significantly from experienced examiners, most differences were <2Δ suggesting good reliability of inexperienced examiners’ measurements. Examiner bias did not have a substantial effect on inexperienced examiner measurements; however, increased dissociation resulted in larger measured deviations for all examiners. PMID:20125058

The age of a bruise may be of interest to forensic investigators. Previous research has demonstrated that an alternative light source may assist in the visualisation of faint or non-visible bruises. This project aimed to determine if an alternative light source could be utilised to assist investigators estimate the age of a bruise. Forty braises, sustained from blunt force trauma, were examined from 30 healthy subjects. The age of the bruises ranged from 2 to 231 h (mean = 74.6, median = 69.0). Alternative light source (polilight) illumination at 415 and 450 nm was used. The black and white photographs obtained were assessed using densitometry. A statistical analysis indicated that there was no correlation between time and the mean densitometry values. The alternative light source used in this study was unable to assist in determining the age of a bruise.

In this paper, the actuarial method of multiple decrement life table analysis of censored, longitudinal data is examined. The discussion is organized in terms of the first segment of usage of an intrauterine device. Weaknesses of the actuarial approach are pointed out, and an alternative approach, based on the classical model of competing risks, is proposed. Finally, the actuarial and the alternative method of analyzing censored data are compared, using data from the Taichung Medical Study on Intrauterine Devices.

Revisiting the returns-volume relationship: Time variation, alternative measures and the financial crisis

NASA Astrophysics Data System (ADS)

Cook, Steve; Watson, Duncan

2017-03-01

Following its introduction in the seminal study of Osborne (1959), a voluminous literature has emerged examining the returns-volume relationship for financial assets. The present paper revisits this relationship in an examination of the FTSE100 which extends the existing literature in two ways. First, alternative daily measures of the FTSE100 index are used to create differing returns and absolute returns series to employ in an examination of returns-volume causality. Second, rolling regression analysis is utilised to explore potential time variation in the returns-volume relationship. The findings obtained depict a hitherto unconsidered complexity in this relationship with the type of returns series considered and financial crisis found to be significant underlying factors. The implications of the newly derived results for both the understanding of the nature of the returns-volume relationship and the development of theories in connection to it are discussed.

Cost-effectiveness analysis of mammography and clinical breast examination strategies

PubMed Central

Ahern, Charlotte Hsieh; Shen, Yu

2009-01-01

Purpose Breast cancer screening by mammography and clinical breast exam are commonly used for early tumor detection. Previous cost-effectiveness studies considered mammography alone or did not account for all relevant costs. In this study, we assessed the cost-effectiveness of screening schedules recommended by three major cancer organizations and compared them with alternative strategies. We considered costs of screening examinations, subsequent work-up, biopsy, and treatment interventions after diagnosis. Methods We used a microsimulation model to generate women’s life histories, and assessed screening and treatment impacts on survival. Using statistical models, we accounted for age-specific incidence, preclinical disease duration, and age-specific sensitivity and specificity for each screening modality. The outcomes of interest were quality-adjusted life years (QALYs) saved and total costs with a 3% annual discount rate. Incremental cost-effectiveness ratios were used to compare strategies. Sensitivity analyses were performed by varying some of the assumptions. Results Compared to guidelines from the National Cancer Institute and the U.S. Preventive Services Task Force, alternative strategies were more efficient. Mammography and clinical breast exam in alternating years from ages 40 to 79 was a cost-effective alternative compared to the guidelines, costing $35,500 per QALY saved compared with no screening. The American Cancer Society guideline was the most effective and the most expensive, costing over $680,000 for an added QALY compared to the above alternative. Conclusion Screening strategies with lower costs and benefits comparable to those currently recommended should be considered for implementation in practice and for future guidelines. PMID:19258473

Işıkay S. The behavior pattern of parents of patients with subacute sclerosing panencephalitis concerning alternative medicine. Turk J Pediatr 2017; 59: 288-294. The aim of the study was to examine the attitude of the parents of Subacute Sclerosing Panencephalitis (SSPE) patients regarding alternative treatment methods and compare with those of the parents of epilepsy patients. The study comprised 39 SSPE and 53 epilepsy patients who were under follow-up in Gaziantep Children`s Hospital. A questionnaire designed to inquire about the knowledge (13 questions) and behavior (11 questions) of parents about alternative medicine methods was given to the caregiver of all patients. The ratio of parents using alternative medicine methods was 29/39 (74.4%) in the SSPE group and 8/53 (15.1%) in the epilepsy group. Less than half of the parents of SSPE patients reported talking about it with their doctors. These results show parents facing a chronic debilitating disease frequently seek benefit from alternative methods. Most define this treatment as complementary to the established medical treatment. However, potential and unrecognized adverse events of alternative methods and their interference with regular medical treatment can be of importance, especially because treating physicians are seldom informed about concurrent use.

Bar and club tobacco promotions in the alternative press: targeting young adults.

PubMed

Sepe, Edward; Glantz, Stanton A

2002-01-01

This study examined changes in tobacco promotions in the alternative press in San Francisco and Philadelphia from 1994 to 1999. A random sample of alternative newspapers was analyzed, and a content analysis was conducted. Between 1994 and 1999, numbers of tobacco advertisements increased from 8 to 337 in San Francisco and from 8 to 351 in Philadelphia. Product advertisements represented only 45% to 50% of the total; the remaining advertisements were entertainment-focused promotions, mostly bar-club and event promotions. The tobacco industry has increased its use of bars and clubs as promotional venues and has used the alternative press to reach the young adults who frequent these establishments. This increased targeting of young adults may be associated with an increase in smoking among this group.

2013-09-01

Case-based instruction has been regarded by many as a viable alternative to traditional lecture-based education and training. However, little is known about how case-based training techniques impact training effectiveness. This study examined the effects of two such techniques: (a) presentation of alternative outcome scenarios to a case, and (b) conducting a structured outcome evaluation. Consistent with the hypotheses, results indicate that presentation of alternative outcome scenarios reduced knowledge acquisition, reduced sensemaking and ethical decision-making strategy use, and reduced decision ethicality. Conducting a structured outcome evaluation had no impact on these outcomes. Results indicate that those who use case-based instruction should take care to use clear, less complex cases with only a singular outcome if they are seeking these types of outcomes.

Metacognition and abstract reasoning.

PubMed

Markovits, Henry; Thompson, Valerie A; Brisson, Janie

2015-05-01

The nature of people's meta-representations of deductive reasoning is critical to understanding how people control their own reasoning processes. We conducted two studies to examine whether people have a metacognitive representation of abstract validity and whether familiarity alone acts as a separate metacognitive cue. In Study 1, participants were asked to make a series of (1) abstract conditional inferences, (2) concrete conditional inferences with premises having many potential alternative antecedents and thus specifically conducive to the production of responses consistent with conditional logic, or (3) concrete problems with premises having relatively few potential alternative antecedents. Participants gave confidence ratings after each inference. Results show that confidence ratings were positively correlated with logical performance on abstract problems and concrete problems with many potential alternatives, but not with concrete problems with content less conducive to normative responses. Confidence ratings were higher with few alternatives than for abstract content. Study 2 used a generation of contrary-to-fact alternatives task to improve levels of abstract logical performance. The resulting increase in logical performance was mirrored by increases in mean confidence ratings. Results provide evidence for a metacognitive representation based on logical validity, and show that familiarity acts as a separate metacognitive cue.

Alternative sample sizes for verification dose experiments and dose audits

ISO 11137 (1995), "Sterilization of Health Care Products—Requirements for Validation and Routine Control—Radiation Sterilization", provides sampling plans for performing initial verification dose experiments and quarterly dose audits. Alternative sampling plans are presented which provide equivalent protection. These sampling plans can significantly reduce the cost of testing. These alternative sampling plans have been included in a draft ISO Technical Report (type 2). This paper examines the rational behind the proposed alternative sampling plans. The protection provided by the current verification and audit sampling plans is first examined. Then methods for identifying equivalent plans are highlighted. Finally, methods for comparing the cost associated with the different plans are provided. This paper includes additional guidance for selecting between the original and alternative sampling plans not included in the technical report.

1997-01-01

This report presents the results of a study of nonthermal treatment technologies. The study consisted of a systematic assessment of five nonthermal treatment alternatives. The treatment alternatives consist of widely varying technologies for safely destroying the hazardous organic components, reducing the volume, and preparing for final disposal of the contact-handled mixed low-level waste (MLLW) currently stored in the US Department of Energy complex. The alternatives considered were innovative nonthermal treatments for organic liquids and sludges, process residue, soil and debris. Vacuum desorption or various washing approaches are considered for treatment of soil, residue and debris. Organic destruction methods include mediatedmore » electrochemical oxidation, catalytic wet oxidation, and acid digestion. Other methods studied included stabilization technologies and mercury separation of treatment residues. This study is a companion to the integrated thermal treatment study which examined 19 alternatives for thermal treatment of MLLW waste. The quantities and physical and chemical compositions of the input waste are based on the inventory database developed by the US Department of Energy. The Integrated Nonthermal Treatment Systems (INTS) systems were evaluated using the same waste input (2,927 pounds per hour) as the Integrated Thermal Treatment Systems (ITTS). 48 refs., 68 figs., 37 tabs.« less

Changes in use of cigarettes and non-cigarette alternative products among college students.

Loukas, Alexandra; Batanova, Milena; Fernandez, Alejandra; Agarwal, Deepti

2015-10-01

The present study examined change in use of various smoked and smokeless non-cigarette alternative products in a sample of college students, stratified by current, or past 30-day, cigarette smoking status. Participants were 698 students from seven four-year colleges in Texas. Participants completed two waves of online surveys regarding tobacco use, knowledge, and attitudes, with 14 months between each wave. The most prevalent products used by the entire sample at Wave 1 were cigarettes, followed by hookah, cigars/cigarillos/little cigars, and electronic cigarettes (e-cigarettes). At Wave 2, prevalence of e-cigarette use surpassed use of cigars/cigarillos/little cigars. Snus and chew/snuff/dip were relatively uncommon at both waves. Examination of change in use indicated that e-cigarette use increased across time among both current cigarette smokers and non-cigarette smokers. Prevalence of current e-cigarette use doubled across the 14-month period to 25% among current smokers and tripled to 3% among non-cigarette smokers. Hookah use also increased across time, but only among non-cigarette smokers, whereas it decreased among current cigarette smokers. Use of all other non-cigarette alternatives remained unchanged across time. Logistic regression analysis was used to examine the socio-demographic predictors of Wave 2 e-cigarette use, the only product that increased in use among both current cigarette smokers and non-cigarette smokers. Results indicated that Wave 1 current cigarette use and Wave 1 current e-cigarette use, but not gender, age, or race/ethnicity, were significantly associated with Wave 2 e-cigarette use. Findings underscore the need to track changes in the use of non-cigarette alternatives and call for additional research examining the factors contributing to change in use.

2016-09-01

The fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) characterizes the dissociative subtype of posttraumatic stress disorder (PTSD) in terms of the individual meeting the criteria for PTSD and additionally reporting symptoms of depersonalization and/or derealization. The current study aimed to examine whether a dissociative PTSD profile may include alternative features of dissociation and whether it could be differentiated from a nondissociative PTSD profile on certain psychopathologies and demographics. Data from 309 trauma-exposed participants, collected through Amazon Mechanical Turk, were subjected to latent profile analysis. Regression analyses were used to examine the predictors of latent classes. Three discrete profiles named Baseline, PTSD, and Dissociative profile were uncovered. All examined features of dissociation were significantly elevated in the Dissociative profile. Anxiety, male sex, being employed, and having a minority racial background significantly predicted the Dissociative profile relative to the PTSD profile. The study points to the importance of alternative symptoms of dissociation in the dissociative PTSD subtype beyond the symptoms of depersonalization and derealization.

An alternative approach to characterize nonlinear site effects

Zhang, R.R.; Hartzell, S.; Liang, J.; Hu, Y.

2005-01-01

This paper examines the rationale of a method of nonstationary processing and analysis, referred to as the Hilbert-Huang transform (HHT), for its application to a recording-based approach in quantifying influences of soil nonlinearity in site response. In particular, this paper first summarizes symptoms of soil nonlinearity shown in earthquake recordings, reviews the Fourier-based approach to characterizing nonlinearity, and offers justifications for the HHT in addressing nonlinearity issues. This study then uses the HHT method to analyze synthetic data and recordings from the 1964 Niigata and 2001 Nisqually earthquakes. In doing so, the HHT-based site response is defined as the ratio of marginal Hilbert amplitude spectra, alternative to the Fourier-based response that is the ratio of Fourier amplitude spectra. With the Fourier-based approach in studies of site response as a reference, this study shows that the alternative HHT-based approach is effective in characterizing soil nonlinearity and nonlinear site response.

In January 2012, the National Renewable Energy Laboratory delivered to the Department of the Interior the first part of a study on Navajo Generating Station (Navajo GS) and the likely impacts of BART compliance options. That document establishes a comprehensive baseline for the analysis of clean energy alternatives, and their ability to achieve benefits similar to those that Navajo GS currently provides. This analysis is a supplement to NREL's January 2012 study. It provides a high level examination of several clean energy alternatives, based on the previous analysis. Each has particular characteristics affecting its relevance as an alternative to Navajomore » GS. It is assumed that the development of any alternative resource (or portfolio of resources) to replace all or a portion of Navajo GS would occur at the end of a staged transition plan designed to reduce economic disruption. We assume that replacing the federal government's 24.3% share of Navajo GS would be a cooperative responsibility of both the U.S. Bureau of Reclamation (USBR) and the Central Arizona Water Conservation District (CAWCD).« less

Design knowledge capture for a corporate memory facility

NASA Technical Reports Server (NTRS)

Boose, John H.; Shema, David B.; Bradshaw, Jeffrey M.

1990-01-01

Currently, much of the information regarding decision alternatives and trade-offs made in the course of a major program development effort is not represented or retained in a way that permits computer-based reasoning over the life cycle of the program. The loss of this information results in problems in tracing design alternatives to requirements, in assessing the impact of change in requirements, and in configuration management. To address these problems, the problem was studied of building an intelligent, active corporate memory facility which would provide for the capture of the requirements and standards of a program, analyze the design alternatives and trade-offs made over the program's lifetime, and examine relationships between requirements and design trade-offs. Early phases of the work have concentrated on design knowledge capture for the Space Station Freedom. Tools are demonstrated and extended which helps automate and document engineering trade studies, and another tool is being developed to help designers interactively explore design alternatives and constraints.

It has been proved that lactate-4.25% dialysate could result in peritoneal fibrosis by inducing alternative activation of macrophages in our previous study, but the mechanism of high glucose-induced alternative activation has not been elucidated. This study was, therefore, to investigate the mechanism by high glucose stimuli. In this study, Raw264.7 (murine macrophage cell line) cells were cultured and stimulated by 4.25% glucose medium, and mannitol medium was used as osmotic pressure control. Cells were harvested at 0 h, 4 h, 8 h, and 12 h to examine the expression of Arg-1, CD206, and p-Akt. After blocking PI3K by LY294002, the expression of Arg-1, CD206, and p-Akt was examined again. The expression of Arg-1 and CD206 was increased in a time-dependent manner induced by high glucose medium. On the contrary, there was mainly no Agr-1 or CD206 expressed in cells cultured in the mannitol medium with the same osmotic pressure. What's more, Akt was phosphorylated at the eighth hour stimulated by high glucose medium, and LY294002 inhibited the expression of Arg-1 and CD206 by blocking the phosphorylation of Akt. Our study indicated that high glucose rather than high osmotic pressure induced M2 phenotype via PI3K/Akt signaling pathway.

Poh-Ai Cheong, Irene; Treagust, David; Kyeleve, Iorhemen J.; Oh, Peck-Yoke

2010-12-01

In this study, a two-tier diagnostic test for understanding malaria was developed and administered to 314 Bruneian students in Year 12 and in a nursing diploma course. The validity, reliability, difficulty level, discriminant indices, and reading ability of the test were examined and found to be acceptable in terms of measuring students' understanding and identifying alternative conceptions with respect to malaria. Results showed that students' understanding of malaria was high for content, low for reasons, and limited and superficial for both content and reasons. The instrument revealed several common alternative conceptual understandings students' hold about malaria. The MalariaTT2 instrument developed could be used in classroom lessons for challenging alternative conceptions and enhancing conceptions of malaria.

Is complementary and alternative therapy effective for women in the climacteric period?

PubMed

Kim, Mi Young; Choi, Seung Do; Ryu, Aeli

2015-04-01

Vasomotor symptoms start about 2 years prior to menopause in women who are approaching menopause, and early menopause symptoms appear including emotional disturbance and anxiety, followed by physical changes such as vaginal dryness, urinary incontinence and skin wrinkles. As time progresses, osteoporosis, cardiovascular diseases, and dementia occur consecutively. Hormone therapy is primarily considered for the relief of menopause symptoms in postmenopausal women. However, as hormone replacement has emerged as a therapy that increases the potential risk of thrombosis, cerebral infarction and breast cancer, complementary and alternative medicine has drawn much attention. This study aimed to examine the types and effects of evidence-based complementary and alternative therapies that are currently used.

Kalb, M

1983-07-01

Despite soaring divorce rates and the effect of divorce on the individual, family, and society, professional scientific literature examining the factors governing the decision to divorce has been scant. The author suggests that the key variable affecting the decision to divorce can best be understood through an exploration of the individual's conception of the alternative. The factors that comprise the conception of the alternative are discussed and the problems inherent in its valid construction by the patient are examined. The therapeutic implementation of this conception is outlined.

PubMed

Helle, Ashley C; Trull, Timothy J; Widiger, Thomas A; Mullins-Sweatt, Stephanie N

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.

Near Infrared Imaging as a Diagnostic Tool for Detecting Enamel Demineralization: An in vivo Study

NASA Astrophysics Data System (ADS)

Lucas, Seth Adam

Background and Objectives: For decades there has been an effort to develop alternative optical methods of imaging dental decay utilizing non-ionizing radiation methods. The purpose of this in-vivo study was to demonstrate whether NIR can be used as a diagnostic tool to evaluate dental caries and to compare the sensitivity and specificity of this method with that of conventional methods, including bitewing x-rays and visual inspection. Materials and Methods: 31 test subjects (n=31) from the UCSF orthodontic clinic undergoing orthodontic treatment with planned premolar extractions were recruited. Calibrated examiners performed caries detection examinations using conventional methods: bitewing radiographs and visual inspection. These findings were compared with the results from NIR examinations: transillumination and reflectance. To confirm the results found in the two different detection methods, a gold standard was used. After teeth were extracted, polarized light microscopy and transverse microradiography were performed. Results: A total of 87 premolars were used in the study. NIR identified the occlusal lesions with a sensitivity of 71% and a specificity of 77%, whereas, the visual examination had a sensitivity of only 40% and a specifity of 39%. For interproximal lesions halfway to DEJ, specificity remained constant, but sensitivity improved to 100% for NIR and 75% for x-rays. Conclusions: The results of this preliminary study demonstrate that NIR is just as effective at detecting enamel interproximal lesions as standard dental x-rays. NIR was more effective at detecting occlusal lesions than visual examination alone. NIR shows promise as an alternative diagnostic tool to the conventional methods of x-rays and visual examination and provides a non-ionizing radiation technique.

Traditional and alternative community food security interventions in Montréal, Québec: different practices, different people.

Roncarolo, Federico; Adam, Caroline; Bisset, Sherri; Potvin, Louise

2015-04-01

Food insecurity is steadily increasing in developed countries. Traditional interventions adopted to tackle food insecurity, like food banks, address the urgent need for food. By contrast, alternative interventions, such as community gardens and kitchens, are oriented towards social integration and the development of mutual aid networks. The objective of this paper is to examine whether the populations served by traditional and alternative interventions in food security differ according to measures of vulnerability. We studied newly registered participants to food security interventions. Participants were selected from a random sample of food security community organizations in a two-stage cluster sampling frame. The categorizing variable was participation in a community organization providing either traditional interventions or alternative interventions. Seven measures of vulnerability were used: food security; perceived health; civic participation; perceived social support of the primary network, social isolation, income and education. Regression multilevel models were used to assess associations. 711 participants in traditional interventions and 113 in alternative interventions were enrolled in the study. Between group differences were found with respect to food insecurity, health status perception, civic participation, education and income, but not with respect to social isolation or perceived social support from primary social network. Traditional and alternative food security interventions seem to reach different populations. Participants in traditional interventions were found to have less access to resources, compared to those in alternative interventions. Thus, new participants in traditional interventions may have higher levers of vulnerability than those in alternative interventions.

Using the regulation of accuracy to study performance when the correct answer is not known.

PubMed

Luna, Karlos; Martín-Luengo, Beatriz

2017-08-01

We examined memory performance in multiple-choice questions when correct answers were not always present. How do participants answer when they are aware that the correct alternative may not be present? To answer this question we allowed participants to decide on the number of alternatives in their final answer (the plurality option), and whether they wanted to report or withhold their answer (report option). We also studied the memory benefits when both the plurality and the report options were available. In two experiments participants watched a crime and then answered questions with five alternatives. Half of the questions were presented with the correct alternative and half were not. Participants selected one alternative and rated confidence, then selected three alternatives and again rated confidence, and finally indicated whether they preferred the answer with one or with three alternatives (plurality option). Lastly, they decided whether to report or withhold the answer (report option). Results showed that participants' confidence in their selections was higher, that they chose more single answers, and that they preferred to report more often when the correct alternative was presented. We also attempted to classify a posteriori questions as either presented with or without the correct alternative from participants' selection. Classification was better than chance, and encouraging, but the forensic application of the classification technique is still limited since there was a large percentage of responses that were incorrectly classified. Our results also showed that the memory benefits of both plurality and report options overlap. © 2017 Scandinavian Psychological Associations and John Wiley & Sons Ltd.

Counterbalancing in smoking cue research: a critical analysis.

PubMed

Sayette, Michael A; Griffin, Kasey M; Sayers, W Michael

2010-11-01

Cue exposure research has been used to examine key issues in smoking research, such as predicting relapse, testing new medications, investigating the neurobiology of nicotine dependence, and examining reactivity among smokers with comorbid psychopathologies. Determining the order that cues are presented is one of the most critical steps in the design of these investigations. It is widely assumed that cue exposure studies should counterbalance the order in which smoking and control (neutral) cues are presented. This article examines the premises underlying the use of counterbalancing in experimental research, and it evaluates the degree to which counterbalancing is appropriate in smoking cue exposure studies. We reviewed the available literature on the use of counterbalancing techniques in human smoking cue exposure research. Many studies counterbalancing order of cues have not provided critical analyses to determine whether this approach was appropriate. Studies that have reported relevant data, however, suggest that order of cue presentation interacts with type of cue (smoking vs. control), which raises concerns about the utility of counterbalancing. Primarily, this concern arises from potential carryover effects, in which exposure to smoking cues affects subsequent responding to neutral cues. Cue type by order of cue interactions may compromise the utility of counterbalancing. Unfortunately, there is no obvious alternative that is optimal across studies. Strengths and limitations of several alternative designs are considered, and key questions are identified to advance understanding of the optimal conditions for conducting smoking cue exposure studies.

2000-01-01

The Alternate Propulsion Subsystem Concepts contract had seven tasks defined that are reported under this contract deliverable. The tasks were: FAA Restart Study, J-2S Restart Study, Propulsion Database Development. SSME Upper Stage Use. CERs for Liquid Propellant Rocket Engines. Advanced Low Cost Engines, and Tripropellant Comparison Study. The two restart studies, F-1A and J-2S, generated program plans for restarting production of each engine. Special emphasis was placed on determining changes to individual parts due to obsolete materials, changes in OSHA and environmental concerns, new processes available, and any configuration changes to the engines. The Propulsion Database Development task developed a database structure and format which is easy to use and modify while also being comprehensive in the level of detail available. The database structure included extensive engine information and allows for parametric data generation for conceptual engine concepts. The SSME Upper Stage Use task examined the changes needed or desirable to use the SSME as an upper stage engine both in a second stage and in a translunar injection stage. The CERs for Liquid Engines task developed qualitative parametric cost estimating relationships at the engine and major subassembly level for estimating development and production costs of chemical propulsion liquid rocket engines. The Advanced Low Cost Engines task examined propulsion systems for SSTO applications including engine concept definition, mission analysis. trade studies. operating point selection, turbomachinery alternatives, life cycle cost, weight definition. and point design conceptual drawings and component design. The task concentrated on bipropellant engines, but also examined tripropellant engines. The Tripropellant Comparison Study task provided an unambiguous comparison among various tripropellant implementation approaches and cycle choices, and then compared them to similarly designed bipropellant engines in the SSTO mission This volume overviews each of the tasks giving its objectives, main results. and conclusions. More detailed Final Task Reports are available on each individual task.

Alternatives to animal testing: research, trends, validation, regulatory acceptance.

PubMed

Huggins, Jane

2003-01-01

Current trends and issues in the development of alternatives to the use of animals in biomedical experimentation are discussed in this position paper. Eight topics are considered and include refinement of acute toxicity assays; eye corrosion/irritation alternatives; skin corrosion/irritation alternatives; contact sensitization alternatives; developmental/reproductive testing alternatives; genetic engineering (transgenic) assays; toxicogenomics; and validation of alternative methods. The discussion of refinement of acute toxicity assays is focused primarily on developments with regard to reduction of the number of animals used in the LD(50) assay. However, the substitution of humane endpoints such as clinical signs of toxicity for lethality in these assays is also evaluated. Alternative assays for eye corrosion/irritation as well as those for skin corrosion/irritation are described with particular attention paid to the outcomes, both successful and unsuccessful, of several validation efforts. Alternative assays for contact sensitization and developmental/reproductive toxicity are presented as examples of methods designed for the examination of interactions between toxins and somewhat more complex physiological systems. Moreover, genetic engineering and toxicogenomics are discussed with an eye toward the future of biological experimentation in general. The implications of gene manipulation for research animals, specifically, are also examined. Finally, validation methods are investigated as to their effectiveness, or lack thereof, and suggestions for their standardization and improvement, as well as implementation are reviewed.

Alternatives to Sedation and General Anesthesia in Pediatric Magnetic Resonance Imaging: A Literature Review.

PubMed

McGuirt, Delaney

2016-09-01

To assess alternatives to sedation and general anesthesia to prepare children for magnetic resonance (MR) imaging examinations. Online databases were searched for articles discussing methods of preparing children for MR imaging procedures. Because of the large number of articles returned, criteria were limited to only studies that prepared patients without the use of sedation or general anesthesia. Twenty-four studies were deemed appropriate for inclusion in the review. The following methods emerged as alternatives to pediatric sedation: mock scanners, MR-compatible audiovisual systems, feed-sleep manipulation, play therapy, infant incubators/immobilizers, photo diaries, sucrose solutions, and guided imagery. The approaches with the most extensive research were mock MR scanners and feed-sleep manipulation. Evidence supports the use of these alternative techniques as valid substitutes for pediatric sedation and general anesthesia. To reduce the risks associated with sedation of pediatric patients, institutions could implement the alternatives discussed in this review. Cost analyses should be conducted first because some methods are more expensive than others. Finally, further research is needed to better assess the effectiveness of lesser-practiced methods, including photo diaries, sucrose solutions, and guided imagery. ©2016 American Society of Radiologic Technologists.

Objective evaluation of binaural summation through acoustic reflex measures.

A previous study [Rawool, V. W. (2016). Auditory processing deficits: Assessment and intervention. New York, NY: Thieme Medical Publishers, Inc., pp. 186-187] demonstrated objective assessment of binaural summation through right contralateral acoustic reflex thresholds (ARTs) in women. The current project examined if previous findings could be generalised to men and to the left ear. Cross-sectional. Sixty individuals participated in the study. Left and right contralateral ARTs were obtained in two conditions. In the alternated condition, the probe tone presentation was alternated with the presentation of the reflex activating clicks. In the simultaneous condition, the probe tone and the clicks were presented simultaneously. Binaural summation was calculated by subtracting the ARTs obtained in the simultaneous condition from the ARTs obtained in the alternated condition. MANOVA on ARTs revealed no significant gender or ear effects. The ARTs were significantly lower/better in the simultaneous condition compared to the alternated condition. Binaural summation was 4 dB or higher in 88% of the ears and 6 dB or higher in 76% of ears. Stimulation of six out of the total 120 (0.5%) ears resulted in worse thresholds in the simultaneous condition compared with the alternating condition, suggesting binaural interference.

Plotkin, S. E.; Energy Systems

2007-03-01

This report describes the results of an effort to identify key analytic issues associated with modeling a transition to hydrogen as a fuel for light duty vehicles, and using insights gained from this effort to suggest ways to improve ongoing modeling efforts. The study reported on here examined multiple hydrogen scenarios reported in the literature, identified modeling issues associated with those scenario analyses, and examined three DOE-sponsored hydrogen transition models in the context of those modeling issues. The three hydrogen transition models are HyTrans (contractor: Oak Ridge National Laboratory), MARKAL/DOE* (Brookhaven National Laboratory), and NEMS-H2 (OnLocation, Inc). The goals ofmore » these models are (1) to help DOE improve its R&D effort by identifying key technology and other roadblocks to a transition and testing its technical program goals to determine whether they are likely to lead to the market success of hydrogen technologies, (2) to evaluate alternative policies to promote a transition, and (3) to estimate the costs and benefits of alternative pathways to hydrogen development.« less

2008-12-01

This study investigated the generation and management of demolition waste (DW) in Cyprus. A methodology has been developed and applied for the estimation of the quantities of the waste stream under examination, since quantitative primary data were not available. The existing situation relating to the practices applied for the management of DW was investigated and assessed. Furthermore, a multi-criteria analysis method (PROMETHEE II) was developed and applied in order to examine alternative systems that could be implemented for the management of the DW in the country. In particular, nine management systems (scenarios) were examined, evaluated and ranked according to their efficiency using seventeen individual criteria, divided into four groups (social-legislative, environmental, economic and technical). The ranking of the alternative waste management scenarios indicated that the optimum management system for possible implementation in the island included complete selective demolition procedures and transfer of mixed recyclable materials to the recycling centre and non-recyclable material to landfill.

Consider the alternative: The effects of causal knowledge on representing and using alternative hypotheses in judgments under uncertainty.

PubMed

Hayes, Brett K; Hawkins, Guy E; Newell, Ben R

2016-05-01

Four experiments examined the locus of impact of causal knowledge on consideration of alternative hypotheses in judgments under uncertainty. Two possible loci were examined; overcoming neglect of the alternative when developing a representation of a judgment problem and improving utilization of statistics associated with the alternative hypothesis. In Experiment 1, participants could search for information about the various components of Bayes's rule in a diagnostic problem. A majority failed to spontaneously search for information about an alternative hypothesis, but this bias was reduced when a specific alternative hypothesis was mentioned before search. No change in search patterns was found when a generic alternative cause was mentioned. Experiments 2a and 2b broadly replicated these patterns when participants rated or made binary judgments about the relevance of each of the Bayesian components. In contrast, Experiment 3 showed that when participants were given the likelihood of the data given a focal hypothesis p(D|H) and an alternative hypothesis p(D|¬H), they gave estimates of p(H|D) that were consistent with Bayesian principles. Additional causal knowledge had relatively little impact on such judgments. These results show that causal knowledge primarily affects neglect of the alternative hypothesis at the initial stage of problem representation.

The "I" in us, or the eye on us? Regulatory focus, commitment and derogation of an attractive alternative person.

PubMed

Rodrigues, David; Lopes, Diniz; Kumashiro, Madoka

2017-01-01

When individuals are highly committed to their romantic relationship, they are more likely to engage in pro-relationship maintenance mechanisms. The present research expanded on the notion that commitment redirects self-oriented goals to consider broader relational goals and examined whether commitment interacts with a promotion and prevention focus to activate derogation of attractive alternatives. Three studies used cross-sectional and experimental approaches. Study 1 showed that romantically involved individuals predominantly focused on promotion, but not prevention, reported less initial attraction to an attractive target than single individuals, especially when highly committed to their relationship. Study 2 showed that romantically involved individuals induced in a promotion focus, compared to those in prevention focus, reported less initial attraction, but only when more committed to their relationship. Regardless of regulatory focus manipulation, more committed individuals were also less likely to perceive quality among alternative scenarios and to be attentive to alternative others in general. Finally, Study 3 showed that romantically involved individuals induced in promotion focus and primed with high commitment reported less initial attraction, than those primed with low commitment, or than those induced in prevention focus. Once again, for these latter no differences occurred according to commitment prime. Together, the findings suggest that highly committed promotion focused individuals consider broader relationship goals and activate relationship maintenance behaviors such as derogation of attractive alternatives to promote their relationship.

1. The influence of salt (sodium chloride; NaCl) (an additional 6% in the diet) and that of a novel sodium-reduced, potassium-, magnesium-, and L-lysine-enriched salt alternative on the cardiovascular effects of ramipril was studied in stroke-prone spontaneously hypertensive rats in a 6-week study. The intake of sodium chloride was adjusted to the same level by adding the salt alternative at a 1.75 times higher amount than regular salt. 2. Salt produced a marked rise in blood pressure and induced cardiac hypertrophy and significant mortality, while the salt alternative neither increased blood pressure nor caused any mortality and produced less cardiac hypertrophy than salt. 3. Ramipril treatment at a daily dose of 3 mg kg-1 normalized blood pressure and prevented the development of cardiac hypertrophy of rats on control diet. These effects of ramipril were blocked by the addition of salt but were only slightly attenuated by the addition of the salt alternative. The mortality in the salt group was prevented by ramipril. 4. Responses of mesenteric arterial rings in vitro were examined at the end of the study. Salt, but not the salt alternative, increased vascular contractile responses to noradrenaline. Ramipril treatment improved the arterial relaxation responses to acetylcholine and to sodium nitroprusside. The vascular relaxation enhancing effect of ramipril was blocked by salt but only slightly attenuated by the salt alternative. 5. Ramipril treatment did not significantly increase plasma renin activity in the presence or in the absence of salt supplementation. The salt alternative did not cause hyperkalaemia, either alone or in combination with ramipril treatment.(ABSTRACT TRUNCATED AT 250 WORDS) PMID:8032605

Rogowski, Jeannette Roskamp; Byrne, Daniel J.

1990-01-01

In this article, alternative methodologies for recalibration of the diagnosis-related group (DRG) weights are examined. Based on 1984 data, cost and charge-based weights are less congruent than those calculated with 1981 data. Previous studies using 1981 data demonstrated that cost- and charge-based weights were not very different. Charge weights result in higher payments to surgical DRGs and lower payments to medical DRGs, relative to cost weights. At the provider level, charge weights result in higher payments to large urban hospitals and teaching hospitals, relative to cost weights. PMID:10113568

The causes and effects of the Alternative Motor Fuels Act

NASA Astrophysics Data System (ADS)

Liu, Yimin

The corporate average fuel economy (CAFE) standard is the major policy tool to improve the fleet average miles per gallon of automobile manufacturers in the U.S. The Alternative Motor Fuels Act (AMFA) provides special treatment in calculating the fuel economy of alternative fuel vehicles to give manufacturers CAFE incentives to produce more alternative fuel vehicles. AMFA has as its goals an increase in the production of alternative fuel vehicles and a decrease in gasoline consumption and greenhouse gas emissions. This dissertation examines theoretically the effects of the program set up under AMFA. It finds that, under some conditions, this program may actually increase gasoline consumption and greenhouse gas emissions. The dissertation also uses hedonic techniques to examine whether the Alternative Motor Fuels Act (AMFA) has a significant effect on the implicit price of fuel economy and whether the marginal value of vehicle fuel efficiency changes over time. It estimates the change of implicit price in miles per gallon after the production of alternative fuel vehicles (AFVs). Results indicate that every year consumers may evaluate vehicle fuel economy differently, and that since AFVs came to the market, the marginal value of fuel economy from specific companies producing AFVs has decreased. This finding suggests that since the AMFA provides extra Corporate Average Fuel Economy (CAFE) credit for those automakers producing AFVs, the automakers can take advantage of the incentive to produce more profitable conventional vehicles and meet CAFE standards without improving the fleet fuel economy. In this way, manufacturers who produce AFVs are willing to offer a lower price for the fuel economy under the AMFA. Additionally, this paper suggests that the flexible fuel vehicles (FFVs) on the market are not significantly more expensive than comparable conventional vehicles, even if FFVs are also able to run on an alternative fuel and may cost more than conventional vehicles. In other words, consumers may not notice the difference between flexible fuel vehicles and conventional vehicles, or are not willing to pay higher prices for FFVs of the same make and model. When the U.S. House of Representatives passed the Alternative Fuels Motor Act (AMFA) in 1987, the representatives who did not vote outnumbered those who opposed the law. This dissertation uses a bivariate probit model with sample selection to study congressmen's two-step decisions --- whether to vote and then how to vote --- on the bill. Theories of political decision-making are examined and tested by the two-stage congressmen voting procedure, which confirms constituent economic interests, congressmen ideology and interest groups' contributions play important roles in congressmen's decision-making on economic policies. Furthermore, it suggests that ignoring congressmen not voting may lead to biased conclusions or inaccurate estimation of the influences of some factors. This study also compares the results from the two-step process with the results from the sample of congressmen who voted, and calculates the marginal effects bound of every factor on the probability of passing the AMFA.

Dahl, Jon; Figved, Wender; Snorrason, Finnur; Nordsletten, Lars; Röhrl, Stephan M

2013-03-01

Radiostereometry (RSA) is considered to be the most precise and accurate method for wear-measurements in total hip replacement. Post-operative stereoradiographs has so far been necessary for wear measurement. Hence, the use of RSA has been limited to studies planned for RSA measurements. We compared a new RSA method for wear measurements that does not require previous radiographs with conventional RSA. Instead of comparing present stereoradiographs with post-operative ones, we developed a method for calculating the post-operative position of the center of the femoral head on the present examination and using this as the index measurement. We compared this alternative method to conventional RSA in 27 hips in an ongoing RSA study. We found a high degree of agreement between the methods for both mean proximal (1.19 mm vs. 1.14 mm) and mean 3D wear (1.52 mm vs. 1.44 mm) after 10 years. Intraclass correlation coefficients (ICC) were 0.958 and 0.955, respectively (p<0.001 for both ICCs). The results were also within the limits of agreement when plotted subject-by-subject in a Bland-Altman plot. Our alternative method for wear measurements with RSA offers comparable results to conventional RSA measurements. It allows precise wear measurements without previous radiological examinations.

Analysis of carbonated thin liquids in pediatric neurogenic dysphagia

PubMed Central

Lundine, Jennifer P.; Bates, David G.; Yin, Han

2015-01-01

Background Aspiration of liquids is a serious complication of neurological impairments such as traumatic brain injury or stroke. Carbonated liquids have been examined as a possible alternative to thickened liquids to help reduce aspiration in cases of dysphagia in adults, but no published literature to the best of our knowledge has evaluated this technique in children. If carbonated liquids result in safer swallowing in children, they could provide a preferred alternative to thickened liquids. Objective This pilot study examined whether carbonated thin liquids (CARB) improved swallowing compared to noncarbonated thin liquids (NOCARB) for children with neurogenic dysphagia. Materials and methods Twenty-four children admitted to a level I trauma center for acute neurological injury/disease were evaluated via videofluoroscopic swallow studies. Four descriptive outcome measures were contrasted. Results CARB significantly decreased pooling (P=0.0006), laryngeal penetration/aspiration (P=0.0044) and Penetration-Aspiration Scale scores (P=0.0127) when compared to NOCARB. On average, CARB improved scores on the Penetration-Aspiration Scale by 3.7 points for participants who aspirated NOCARB. There was no significant difference in pharyngeal residue noted between CARB and NOCARB (P=0.0625). Conclusion These findings support the hypothesis that carbonated thin liquids may provide an alternative to thickened liquids for children with neurogenic dysphagia. Implications for future research and clinical practice are discussed. PMID:25758792

FORUM: Dynamics and Causation of Environmental Equity, Locally Unwanted Land Uses, and Neighborhood Changes

PubMed

Liu

1997-09-01

/ Why are some environmental risks distributed disproportionately in the neighborhoods of the minorities and the poor? A hypothesis was proposed in a recent study that market dynamics contributed to the current environmental inequity. That is, locally unwanted land uses (LULUs) make the host communities home to more poor people and people of color. This hypothesis was allegedly supported by a Houston case study, whereby its author analyzed the postsiting changes of the socioeconomic characteristics of the neighborhoods surrounding solid waste facilities. I argue that such an analysis of postsiting changes alone is insufficient to test the causation hypothesis. Instead, I propose a conceptual framework for analysis of environmental equity dynamics and causation. I suggest that the presiting neighborhood dynamics and the characteristics of control neighborhoods be analyzed as the first test for the causation hypothesis. Furthermore, I present theories of neighborhood change and then examine alternative hypotheses that these theories offer for explaining neighborhood changes and for the roles of LULUs in neighborhood changes. These alternative hypotheses should be examined when analyzing the relationship between LULUs and neighborhood changes in a metropolitan area. Using this framework of analysis, I revisited the Houston case. First, I found no evidence that provided support for the hypothesis that the presence of LULUs made the neighborhoods home to more blacks and poor people, contrary to the conclusion made by the previous study. Second, I examined alternative hypotheses for explaining neighborhood changes-invasion-succession, other push forces, and neighborhood life-cycle; the former two might offer better explanation.KEY WORDS: Environmental equity and justice; Locally unwanted lane uses; Siting; Market dynamics; Invasion-succession; Neighborhood changes

Studies examining psychosocial and depression assessment programs in maternity settings have not adequately considered the context in which psychosocial assessment occurs or how broader components of integrated care, including clinician decision-making aids, may optimise program delivery and its cost-effectiveness. There is also limited evidence relating to the diagnostic accuracy of symptom-based screening measures used in this context. The Perinatal Integrated Psychosocial Assessment (PIPA) Project was developed to address these knowledge gaps. The primary aims of the PIPA Project are to examine the clinical- and cost-effectiveness of two alternative models of integrated psychosocial care during pregnancy: 'care as usual' (the SAFE START model) and an alternative model (the PIPA model). The acceptability and perceived benefit of each model of care from the perspective of both pregnant women and their healthcare providers will also be assessed. Our secondary aim is to examine the psychometric properties of a number of symptom-based screening tools for depression and anxiety when used in pregnancy. This is a comparative-effectiveness study comparing 'care as usual' to an alternative model sequentially over two 12-month periods. Data will be collected from women at Time 1 (initial antenatal psychosocial assessment), Time 2 (2-weeks after Time 1) and from clinicians at Time 3 for each condition. Primary aims will be evaluated using a between-groups design, and the secondary aim using a within group design. The PIPA Project will provide evidence relating to the clinical- and cost- effectiveness of psychosocial assessment integrated with electronic clinician decision making prompts, and referral options that are tailored to the woman's psychosocial risk, in the maternity care setting. It will also address research recommendations from the Australian (2011) and NICE (2015) Clinical Practice Guidelines. ACTRN12617000932369.

Increasing the power for detecting impairment in older adults with the Faces subtest from Wechsler Memory Scale-III: an empirical trial.

PubMed

Levy, Boaz

2006-10-01

Empirical studies have questioned the validity of the Faces subtest from the WMS-III for detecting impairment in visual memory, particularly among the elderly. A recent examination of the test norms revealed a significant age related floor effect already emerging on Faces I (immediate recall), implying excessive difficulty in the acquisition phase among unimpaired older adults. The current study compared the concurrent validity of the Faces subtest with an alternative measure between 16 Alzheimer's patients and 16 controls. The alternative measure was designed to facilitate acquisition by reducing the sequence of item presentation. Other changes aimed at increasing the retrieval challenge, decreasing error due to guessing and standardizing the administration. Analyses converged to indicate that the alternative measure provided a considerably greater differentiation than the Faces subtest between Alzheimer's patients and controls. Steps for revising the Faces subtest are discussed.

Analysis with the ParaChoice model addresses three barriers from the VTO Multi-Year Program Plan: availability of alternative fuels and electric charging station infrastructure, availability of AFVs and electric drive vehicles, and consumer reluctance to purchase new technologies. In this fiscal year, we first examined the relationship between the availability of alternative fuels and station infrastructure. Specifically, we studied how electric vehicle charging infrastructure affects the ability of EVs to compete with vehicles that rely on mature, conventional petroleum-based fuels. Second, we studied how the availability of less costly AFVs promotes their representation in the LDV fleet. Third, we used ParaChoicemore » trade space analyses to help inform which consumers are reluctant to purchase new technologies. Last, we began analysis of impacts of alternative energy technologies on Class 8 trucks to isolate those that may most efficaciously advance HDV efficiency and petroleum use reduction goals.« less

Although direct examination methods are important for diagnosing leishmaniasis, such methods are often neglected because of their low sensitivity relative to other techniques. Our study aimed to evaluate the performance of bone marrow (BM) thick smears and cytocentrifugation tests as alternatives to direct examination for diagnosing canine visceral leishmaniasis (CVL). Ninety-two dogs exhibiting leishmaniasis seroreactivity were evaluated. The animals were euthanized; and healthy skin, spleen, popliteal lymph node, and BM puncture samples were cultured. BM cultures were used as the reference standard. Of the 92 dogs studied, 85.9% exhibited positive cultures, and Leishmania infantum (synonym Leishmania chagasi) was confirmed in all positive culture cases. The sensitivity rates for cytocentrifugation as well as thin and thick smears were 47.1%, 52.8%, and 77%, respectively. However, no association between the dogs' clinical status and culture or direct examination results was found. To our knowledge, this was the first study to use thick smears and cytocentrifugation for diagnosing CVL. Our results indicate that BM thick smears have a good sensitivity and their use reduces the time required to read slides. Therefore, thick smears can provide a rapid and safe alternative to parasitological confirmation of seroreactive dogs. © The American Society of Tropical Medicine and Hygiene.

Ocular Fundus Photography as an Educational Tool.

PubMed

Mackay, Devin D; Garza, Philip S

2015-10-01

The proficiency of nonophthalmologists with direct ophthalmoscopy is poor, which has prompted a search for alternative technologies to examine the ocular fundus. Although ocular fundus photography has existed for decades, its use has been traditionally restricted to ophthalmology clinical care settings and textbooks. Recent research has shown a role for nonmydriatic fundus photography in nonophthalmic settings, encouraging more widespread adoption of fundus photography technology. Recent studies have also affirmed the role of fundus photography as an adjunct or alternative to direct ophthalmoscopy in undergraduate medical education. In this review, the authors examine the use of ocular fundus photography as an educational tool and suggest future applications for this important technology. Novel applications of fundus photography as an educational tool have the potential to resurrect the dying art of funduscopy. Thieme Medical Publishers 333 Seventh Avenue, New York, NY 10001, USA.

Comparison of Integrated Gasifier-Combined Cycle and AFB-steam turbine systems for industrial cogeneration

Nainiger, J. J.; Abbott, J. M.; Burns, R. K.

1981-01-01

In the cogeneration technology alternatives study (CTAS) a number of advanced coal fired systems were examined and systems using a integrated coal gasifier IGCC or a fluid bed combustor AFB were found to yield attractive cogeneration results in industrial cogeneration applications. A range of site requirements and cogeneration sizing strategies using ground rules based on CTAS were used in comparing an IGCC and an AFB. The effect of time variations in site requirements and the sensitivity to fuel and electricity price assumptions are examined. The economic alternatives of industrial or utility ownership are also considered. The results indicate that the IGCC system has potentially higher fuel and emission savings and could be an attractive option for utility ownership. The AFB steam turbine system has a potentially higher return on investment and could be attractive assuming industrial ownership.

Cancer Care Experiences and the Use of Complementary and Alternative Medicine at End of Life in Nova Scotia’s Black Communities

PubMed Central

Maddalena, Victor J.; Bernard, Wanda Thomas; Etowa, Josephine; Murdoch, Sharon Davis; Smith, Donna; Jarvis, Phyllis Marsh

2016-01-01

Purpose This qualitative study examines the meanings that African Canadians living in Nova Scotia, Canada, ascribe to their experiences with cancer, family caregiving, and their use of complementary and alternative medicine (CAM) at end of life. Design Case study methodology using in-depth interviews were used to examine the experiences of caregivers of decedents who died from cancer in three families. Findings For many African Canadians end of life is characterized by care provided by family and friends in the home setting, community involvement, a focus on spirituality, and an avoidance of institutionalized health services. Caregivers and their families experience multiple challenges (and multiple demands). There is evidence to suggest that the use of CAM and home remedies at end of life are common. Discussion The delivery of palliative care to African Canadian families should consider and support their preference to provide end-of-life care in the home setting. PMID:20220031

Minority mothers' healthcare beliefs, commonly used alternative healthcare practices, and potential complications for infants and children.

PubMed

Hannan, Jean

2015-06-01

Complementary and alternative healthcare practices have increased substantially in the United States especially with low-income ethnic minority mothers. These mothers often have provider mistrust, language barriers, differing health belief systems, and as a result are less likely to seek preventive health screening, access healthcare services, and use alternative remedies for their infants and children that are potentially harmful or lethal. Therefore, the purpose of this article is to examine healthcare beliefs, commonly used alternative healthcare practices, and their potential complications for infants and children. A search of CINAHL and PubMed (1980-2012) was conducted using the following terms: alternative healthcare practice, mothers' health beliefs, cultural health beliefs, folk remedies, and infant health practices. Given the changing U.S. population and an increasing immigrant population, examining alternative healthcare practices mothers use for their infants and children is especially important for providers in addressing healthcare for this group. The use of alternative healthcare practices is rarely discussed by parents with healthcare providers for fear of disapproval. When interviewing ethnic minority mothers and caregivers questions should include the use of alternative healthcare practices for infants and children and information regarding the potential dangers should be provided to them. ©2014 American Association of Nurse Practitioners.

Quantifying asymmetry: ratios and alternatives.

PubMed

Franks, Erin M; Cabo, Luis L

2014-08-01

Traditionally, the study of metric skeletal asymmetry has relied largely on univariate analyses, utilizing ratio transformations when the goal is comparing asymmetries in skeletal elements or populations of dissimilar dimensions. Under this approach, raw asymmetries are divided by a size marker, such as a bilateral average, in an attempt to produce size-free asymmetry indices. Henceforth, this will be referred to as "controlling for size" (see Smith: Curr Anthropol 46 (2005) 249-273). Ratios obtained in this manner often require further transformations to interpret the meaning and sources of asymmetry. This model frequently ignores the fundamental assumption of ratios: the relationship between the variables entered in the ratio must be isometric. Violations of this assumption can obscure existing asymmetries and render spurious results. In this study, we examined the performance of the classic indices in detecting and portraying the asymmetry patterns in four human appendicular bones and explored potential methodological alternatives. Examination of the ratio model revealed that it does not fulfill its intended goals in the bones examined, as the numerator and denominator are independent in all cases. The ratios also introduced strong biases in the comparisons between different elements and variables, generating spurious asymmetry patterns. Multivariate analyses strongly suggest that any transformation to control for overall size or variable range must be conducted before, rather than after, calculating the asymmetries. A combination of exploratory multivariate techniques, such as Principal Components Analysis, and confirmatory linear methods, such as regression and analysis of covariance, appear as a promising and powerful alternative to the use of ratios. © 2014 Wiley Periodicals, Inc.

Male Partners' Investment and Alternatives as Correlates of Women's Coerced First Sexual Intercourse in Chinese Dating Relationships: A Social Exchange Perspective.

PubMed

He, Shanshan; Tsang, Sandra

2016-10-01

Social exchange theory has great potential to help our understanding of dating partners' sexual interaction. Yet, to our knowledge, there is still no empirical study applying this theory to explain sexual coercion in the context of intimate relationships. This study examined the relationship between male partners' social exchange variables (investment and alternatives) and women's coerced first sexual intercourse in dating relationships, within both gender samples (not dyadic data). A total of 927 valid questionnaires were collected by purposive snowball sampling in five main cities in China of college students who were currently in a romantic relationship. Results showed that in the male sample, male partners' investment significantly and positively correlated with emotional manipulation coercive tactics, and their alternatives significantly and positively predicted defection threats as coercive tactics. In the female sample, there were no such observations. The research hypotheses of this study have been partially supported, and its implications and limitations are discussed.

Longer treatment with alternative non-drug reinforcement fails to reduce resurgence of cocaine or alcohol seeking in rats.

PubMed

Nall, Rusty W; Craig, Andrew R; Browning, Kaitlyn O; Shahan, Timothy A

2018-04-02

Provision of alternative non-drug reinforcement is among the most effective methods for treating substance use disorders. However, when alternative reinforcers become unavailable during treatment interruptions or upon cessation of treatment, relapse often occurs. Relapse following the loss of alternative reinforcement is known as resurgence. One factor that could reduce resurgence is longer duration of treatment with alternative reinforcement, but the available data are mixed. Further, the effects of length of treatment have previously only been examined with food seeking. The present experiments directly examined if duration of treatment impacted the magnitude of resurgence of cocaine or alcohol seeking in rats. First, rats were trained to self-administer cocaine (Experiment 1) or alcohol (Experiment 2) by performing a target behavior. Second, target behavior was extinguished and performing an alternative behavior produced an alternative non-drug (i.e., food) reinforcer. Finally, resurgence was assessed following removal of alternative reinforcement after either 5 or 20 sessions of treatment. Treatment duration did not differentially affect resurgence of cocaine seeking in Experiment 1 or Alcohol seeking in Experiment 2. These results suggest that extended treatment with alternative non-drug reinforcement may not decrease propensity to relapse. Further, these results may have implications for treatment of substance use disorders and for theories of resurgence. Copyright © 2017 Elsevier B.V. All rights reserved.

When passion makes the heart grow colder: the role of passion in alternative goal suppression.

PubMed

Bélanger, Jocelyn J; Lafrenière, Marc-André K; Vallerand, Robert J; Kruglanski, Arie W

2013-01-01

Quality of goal engagement and alternative goal suppression were investigated in this research. Integrating the dualistic model of passion (Vallerand et al., 2003) with goal-systems theory (Kruglanski et al., 2002), we hypothesized that obsessive passion--associated with recurrent goal-conflicts--would predict greater alternative goal suppression (i.e., goal-shielding) than would harmonious passion--characterized by effective synthesis of the passionate activity with other life domains. Results from 5 laboratory studies supported these hypotheses. In Study 1, participants' dispositional measures of harmonious and obsessive passion were correlated with an implicit measure of goal-shielding. Obsessive (but not harmonious) passion predicted the suppression of alternative goals and the progressive inhibition of unfamiliar goals. In Study 2, we extended these findings by demonstrating the interrelation between quality of goal engagement and goal-commitment such that goal-shielding effects were enhanced, but only for goals in conflict with other life domains (vs. well-integrated goals). In Study 3, the causal influence of passion on goal-shielding was supported via an experimental manipulation of passion. In Study 4, we replicated and extended Studies 1 and 3 by experimentally demonstrating that obsessive (but not harmonious) passion is a mindset conducive to the development of inhibitory links with alternative goals. Study 5 explored the psychological costs associated with repeated unconscious goal suppression by examining its effects on the depletion of self-regulatory resources. Collectively, the present results suggest that the qualitative distinction between obsessive and harmonious passion has implications for the goal-shielding effect and for subsequent self-regulatory behavior.

The association between caffeine and cognitive decline: examining alternative causal hypotheses.

PubMed

Ritchie, K; Ancelin, M L; Amieva, H; Rouaud, O; Carrière, I

2014-04-01

Numerous studies suggest that higher coffee consumption may reduce the rate of aging-related cognitive decline in women. It is thus potentially a cheap and widely available candidate for prevention programs provided its mechanism may be adequately understood. The assumed effect is that of reduced amyloid deposition, however, alternative pathways notably by reducing depression and diabetes type 2 risk have not been considered. A population study of 1,193 elderly persons examining depressive symptomatology, caffeine consumption, fasting glucose levels, type 2 diabetes onset, serum amyloid, and factors known to affect cognitive performance was used to explore alternative causal models. Higher caffeine consumption was found to be associated with decreased risk of incident diabetes in men (HR = 0.64; 95% CI 0.42-0.97) and increased risk in women (HR = 1.51; 95% CI 1.08-2.11). No association was found with incident depression. While in the total sample lower ratio Aβ42/Aβ40 levels (OR = 1.36, 95% CI 1.05-1.77, p = 0.02) were found in high caffeine consumers, this failed to reach significance when the analyses were stratified by gender. We found no evidence that reduced risk of cognitive decline in women with high caffeine consumption is moderated or confounded by diabetes or depression. The evidence of an association with plasma beta amyloid could not be clearly demonstrated. Insufficient proof of causal mechanisms currently precludes the recommendation of coffee consumption as a public health measure. Further research should focus on the high estrogen content of coffee as a plausible alternative explanation.

Mental disorders frequency alternative and complementary medicine usage among patients with hypertension and type 2 diabetes mellitus.

Keskin, Ahmet; BIlge, Ugur

2014-01-01

Diabetes mellitus (DM) and hypertension (HT) are chronic disorders with which mental disorders may coexist and for which patients may resort to alternative medicine use. Alternative and complementary medicine is a treatment option that patients tend to use. This study is to determine the prevalence of mental disorders among patients diagnosed with DM and HT and their use of alternative medicine methods. Materials and Methods The study was conducted in a primary care setting. The data were collected from the Family Health Center No. 4 at Ηankaya, Ankara, Turkey. It involved patients aged between 18 and 65, who were on follow-up treatment for DM and HT. Patients accepted to participate in the study were administered the sociodemographic data form, the Primary Care Evaluation of Mental Disorders (PRIME-MD) questionnaire and the alternative medicine inquiry form. One hundred and sixteen patients with HT and 119 patients with DM (type 2) were recruited for the study. In this study, 47.4% of HT patients and 53.8% of the DM patients were diagnosed with a PRIME-MD. The most commonly encountered disorder was mood disorders, in 37.1% of the HT patients and 45.4% of the DM patients. In this study, four HT patients (0.3%) and no DM patients stated that they resorted to complimentary medicine, which can use be used alongside conventional medical treatment and may help to feel better and cope better with any chronic condition. All four HT patients were using multivitamin combinations to support the treatment. As the alternative medicine usage was described as treatment used instead of conventional medical treatment we did not find any patient using alternative medicine. Mental disorders may coexist with HT and DM. Some of the HT and DM patients suffering from a mental disorder seek psychiatric support, while others do not. We believe that it is important to examine patients for mental disorders, while being followed-up for a chronic disease.

In recent years, several safety alerts have questioned or restricted the use of some pharmacological alternatives to allogeneic blood transfusion in established indications. In contrast, there seems to be a promotion of other alternatives, based on blood products and/or antifibrinolytic drugs, which lack a solid scientific basis. The Multidisciplinary Autotransfusion Study Group and the Anemia Working Group España convened a multidisciplinary panel of 23 experts belonging to different healthcare areas in a forum for debate to: 1) analyze the different safety alerts referred to certain transfusion alternatives; 2) study the background leading to such alternatives, the evidence supporting them, and their consequences for everyday clinical practice, and 3) issue a weighted statement on the safety of each questioned transfusion alternative, according to its clinical use. The members of the forum maintained telematics contact for the exchange of information and the distribution of tasks, and a joint meeting was held where the conclusions on each of the items examined were presented and discussed. A first version of the document was drafted, and subjected to 4 rounds of review and updating until consensus was reached (unanimously in most cases). We present the final version of the document, approved by all panel members, and hope it will be useful for our colleagues. Copyright © 2015 Elsevier España, S.L.U. and SEMICYUC.

Adolescent cigarette smokers' and non-cigarette smokers' use of alternative tobacco products.

PubMed

Saunders, Charles; Geletko, Karen

2012-08-01

This study uses the most recent data from the nationally representative National Youth Tobacco Survey (NYTS) to examine the use of alternative tobacco products among U.S. cigarette smokers and non-cigarette smokers aged 14-17. Alternative tobacco product use is defined as use of one or more of the following products: smokeless tobacco, cigars, pipes, bidis, or kreteks. Using the results from the 2004, 2006, and 2009 NYTS, multivariate logistic regressions were used to investigate separately the extent of alternative tobacco product use in current cigarette smokers and in those who reported not smoking cigarettes controlling for demographic and other independent influences. The results indicate that for adolescent smokers and nonsmokers, the use of one type of alternative tobacco product made it much more likely the individual would use one or more of the other alternative tobacco products. Non-cigarette smokers using these tobacco products appeared to exhibit symptoms of nicotine dependence comparable to those of cigarette smokers. More information on adolescent use of alternative tobacco products is needed. Current cigarette use declined 3.4% annually over 2004-2009 for the NYTS 14- to 17-year-old population, but this cohort's use of alternative tobacco products was unchanged. The number of adolescents aged 14-17 who did not smoke cigarettes but used alternative tobacco products increased 5.9% per year over the same period. Current surveillance measures need to be expanded in order to gain a more comprehensive understanding of adolescent alternative tobacco use.

The U.S. employment effects of military and domestic spending priorities.

PubMed

Pollin, Robert; Garrett-Peltier, Heidi

2009-01-01

This study focuses on the employment effects of military spending versus alternative domestic spending priorities. The authors begin by introducing the basic input-output modeling technique for considering issues such as these in a systematic way. They then present some simple alternative spending scenarios-namely, devoting $1 billion to the military versus the same amount of money spent for five alternatives: tax cuts that produce increased levels of personal consumption; health care; education; mass transit; and construction targeted at home weatherization and infrastructure repair. The first conclusion in assessing such relative employment effects is straightforward: $1 billion spent on personal consumption, health care, education, mass transit, and construction for home weatherization/infrastructure will all create more jobs in the U.S. economy than would the same $1 billion spent on the military. The authors then examine the pay level of jobs created through these alternative spending priorities and assess the overall welfare effects of the alternative employment outcomes. Combining these alternative domestic spending categories in an effective way can also generate a higher level of compensation for working people in the United States and a better average quality ofjobs.

The aim of this article is to interrogate the pervasive dichotomization of 'conventional' and 'alternative' therapies in popular, academic and medical literature. Specifically, I rethink the concepts such as holism, vitalism, spirituality, natural healing and individual responsibility for health care as taken-for-granted alternative ideologies. I explore how these ideologies are not necessarily 'alternative', but integral to the practice of clinical medicine as well as socially and culturally dominant values, norms and practices related to health and health care in Canada and elsewhere. These reflections address both theoretical and applied concerns central to the study of integration of different medical practices in western industrialized nations such as Canada. Overall, in examining homologies present in both biomedicine and complementary/alternative medicine (CAM), this article rethinks major social practices against binary oppositions by illustrating through literature review that the biomedical and CAM models may be homologous in their original inceptions and in recent cross-fertilizations towards a rigorous approach in medicine. By highlighting biomedicine and CAM as homologous symbolic systems, this article also sheds light on the potential for enhancing dialogue between diverse perspectives to facilitate an integrative health care system that meets multiple consumer needs.

Three studies used videotaped harassment complaints to examine the impact of legal standards on the evaluation of social-sexual conduct at work. Study 1 demonstrated that without legal instructions, college students' judgment strategies were highly variable. Study 2 compared 2 current legal standards, the "severity or pervasiveness test" and a proposed utilitarian alternative (i.e., the rational woman approach). Undergraduate participants taking the perspective of the complainant were more sensitive to offensive conduct than were those adopting an objective perspective. Although the utilitarian altemative further increased sensitivity on some measures, it failed to produce a principled judgment strategy. Finally, Study 3 examined the kinds of errors that full-time workers make when applying the "severity or pervasiveness" test to examine more closely the sensitivity of the subjective approach.

Research on delay discounting has focused largely on nondrug reinforcers in an isomorphic context in which choice is between alternatives that involve the same type of reinforcer. Less often, delay discounting has been studied with drug reinforcers in a more ecologically valid allomorphic context where choice is between alternatives involving different types of reinforcers. The present experiment is the first to examine discounting of drug and nondrug reinforcers in both isomorphic and allomorphic situations using a theoretical model (i.e., the hyperbolic discounting function) that allows for comparisons of discounting rates between reinforcer types and amounts. The goal of the current experiment was to examine discounting of a delayed, nondrug reinforcer (food) by male rhesus monkeys when the immediate alternative was either food (isomorphic situation) or cocaine (allomorphic situation). In addition, we sought to determine whether there was a magnitude effect with delayed food in the allomorphic situation. Choice of immediate food and immediate cocaine increased with amount and dose, respectively. Choice functions for immediate food and cocaine generally shifted leftward as delay increased. Compared to isomorphic situations in which food was the immediate alternative, delayed food was discounted more steeply in allomorphic situations where cocaine was the immediate alternative. Notably, discounting was not affected by the magnitude of the delayed reinforcer. These data indicate that how steeply a delayed nondrug reinforcer is discounted may depend more on the qualitative characteristics of the immediate reinforcer and less on the magnitude of the delayed one.

Counterbalancing in Smoking Cue Research: A Critical Analysis

PubMed Central

Griffin, Kasey M.; Sayers, W. Michael

2010-01-01

Introduction: Cue exposure research has been used to examine key issues in smoking research, such as predicting relapse, testing new medications, investigating the neurobiology of nicotine dependence, and examining reactivity among smokers with comorbid psychopathologies. Determining the order that cues are presented is one of the most critical steps in the design of these investigations. It is widely assumed that cue exposure studies should counterbalance the order in which smoking and control (neutral) cues are presented. This article examines the premises underlying the use of counterbalancing in experimental research, and it evaluates the degree to which counterbalancing is appropriate in smoking cue exposure studies. Methods: We reviewed the available literature on the use of counterbalancing techniques in human smoking cue exposure research. Results: Many studies counterbalancing order of cues have not provided critical analyses to determine whether this approach was appropriate. Studies that have reported relevant data, however, suggest that order of cue presentation interacts with type of cue (smoking vs. control), which raises concerns about the utility of counterbalancing. Primarily, this concern arises from potential carryover effects, in which exposure to smoking cues affects subsequent responding to neutral cues. Conclusions: Cue type by order of cue interactions may compromise the utility of counterbalancing. Unfortunately, there is no obvious alternative that is optimal across studies. Strengths and limitations of several alternative designs are considered, and key questions are identified to advance understanding of the optimal conditions for conducting smoking cue exposure studies.

The “I” in us, or the eye on us? Regulatory focus, commitment and derogation of an attractive alternative person

PubMed Central

2017-01-01

When individuals are highly committed to their romantic relationship, they are more likely to engage in pro-relationship maintenance mechanisms. The present research expanded on the notion that commitment redirects self-oriented goals to consider broader relational goals and examined whether commitment interacts with a promotion and prevention focus to activate derogation of attractive alternatives. Three studies used cross-sectional and experimental approaches. Study 1 showed that romantically involved individuals predominantly focused on promotion, but not prevention, reported less initial attraction to an attractive target than single individuals, especially when highly committed to their relationship. Study 2 showed that romantically involved individuals induced in a promotion focus, compared to those in prevention focus, reported less initial attraction, but only when more committed to their relationship. Regardless of regulatory focus manipulation, more committed individuals were also less likely to perceive quality among alternative scenarios and to be attentive to alternative others in general. Finally, Study 3 showed that romantically involved individuals induced in promotion focus and primed with high commitment reported less initial attraction, than those primed with low commitment, or than those induced in prevention focus. Once again, for these latter no differences occurred according to commitment prime. Together, the findings suggest that highly committed promotion focused individuals consider broader relationship goals and activate relationship maintenance behaviors such as derogation of attractive alternatives to promote their relationship.

Using a Novel Alternative to Drug Choice in a Human Laboratory Model of a Cocaine Binge: A Game of Chance

Vosburg, Suzanne K.; Haney, Margaret; Rubin, Eric; Foltin, Richard W.

2010-01-01

Human laboratory studies have shown that, once initiated, cocaine self-administration is difficult to disrupt using non-drug alternatives. This inpatient study examined whether binge self-administration of cocaine could be altered by an immediate, non-drug reinforcer. Ten cocaine-dependent participants completed 5 consecutive laboratory session days with 2 sessions per day (a model binge), 9 days where cocaine was not available, and subsequent 2 laboratory session days where cocaine was again available (a second model binge). In each laboratory session, participants could choose to either self-administer smoked cocaine or play a game of chance by drawing a pre-determined number of balls from a bingo wheel. Balls were worth monetary amounts from $0 – $20. Participants’ choice to smoke cocaine varied as a function of number of balls drawn. Thus, this game of chance served as an alternative reinforcer to smoking cocaine. Choice varied lawfully as a function of the number of opportunities to earn money indicating that an immediate behavioral alternative can reduce cocaine self-administration after initiation of use. The current model could be used to evaluate whether behavioral and pharmacological manipulations shift choice from cocaine to a non-drug alternative. PMID:20346597

The emergence of trust in clinics of alternative medicine.

Pedersen, Inge Kryger; Hansen, Vibeke Holm; Grünenberg, Kristina

2016-01-01

Demands for alternative medicine have increased since the 1970s in nations in which western scientific evidence has become the basis for health care. This paradox has been the impetus to examine how trust emerges in clinics of alternative medicine. Alternative practitioners are self-regulated and the clients pay out of their own pockets to attend non-authorised treatments with very limited scientific evidence of their effects. Trust is a key issue in this context. However, only a few studies have dealt with the ways in which alternative practitioners win their clients' trust. Drawing on three qualitative studies and informing the empirical findings with a sociological concept of trust, this article provides new empirical insights on how trust emerges in Danish clinics of acupuncture, reflexology and homeopathy. The analysis demonstrates how trust is situational and emerges through both clients' susceptibility and practitioners' individual skill development and strategies, as well as from objects, place and space. Trust is developed on relational and bodily as well as material grounds. It is argued that the dynamics and elements of trust identified do not only minimalise uncertainties but sometimes convert these uncertainties into productive new ways for clients to address their ailments, life circumstances and perspectives. © 2015 Foundation for the Sociology of Health & Illness.

Ranking Schools' Academic Performance Using a Fuzzy VIKOR

Musani, Suhaina; Aziz Jemain, Abdul

2015-06-01

Determination rank is structuring alternatives in order of priority. It is based on the criteria determined for each alternative involved. Evaluation criteria are performed and then a composite index composed of each alternative for the purpose of arranging in order of preference alternatives. This practice is known as multiple criteria decision making (MCDM). There are several common approaches to MCDM, one of the practice is known as VIKOR (Multi-criteria Optimization and Compromise Solution). The objective of this study is to develop a rational method for school ranking based on linguistic information of a criterion. The school represents an alternative, while the results for a number of subjects as the criterion. The results of the examination for a course, is given according to the student percentage of each grade. Five grades of excellence, honours, average, pass and fail is used to indicate a level of achievement in linguistics. Linguistic variables are transformed to fuzzy numbers to form a composite index of school performance. Results showed that fuzzy set theory can solve the limitations of using MCDM when there is uncertainty problems exist in the data.

The rise in alternative respiratory capacity upon aging of potato (Solanum tuberosum) tuber slices is correlated with changes in mitochondrial membrane protein composition and a requirement for cytoplasmic protein synthesis. However, the lack of an antibody specific to the alternative oxidase has, until recently, prevented examination of the alternative oxidase protein(s) itself. We have employed a monoclonal antibody raised against the Sauromatum guttatum alternative oxidase to investigate developmental changes in the alternative pathway of aging potato slice mitochondria and to characterize the potato alternative oxidase by one- and two-dimensional gel electrophoresis. The relative levels of a 36 kilodalton protein parallelmore » the rise in alternative path capacity. A plausible interpretation is that this alternative oxidase protein is synthesized de novo during aging of potato slices.« less

Nikouei, Alireza; Ward, Frank A.

2013-10-01

This paper examines alternative water pricing arrangements that better manage and more accurately reflect conditions of increased water scarcity experienced during drought in Iran. A comprehensive water balance and crop use model compares the existing below cost water pricing model with an alternative two-tiered pricing approach. The tiers reflect two uses of irrigation water. The uses are (1) subsistence level crop production from farm household production of crops for food security and (2) discretionary cropping. Results of the study offer evidence for a reform of Iranian water pricing principles, subject to caveats described by the authors.

Pencil grasps other than the dynamic tripod may be functional for handwriting. This study examined the impact of grasp on handwriting speed and legibility. We videotaped 120 typically developing fourth-grade students while they performed a writing task. We categorized the grasps they used and evaluated their writing for speed and legibility using a handwriting assessment. Using linear regression analysis, we examined the relationship between grasp and handwriting. We documented six categories of pencil grasp: four mature grasp patterns, one immature grasp pattern, and one alternating grasp pattern. Multiple linear regression results revealed no significant effect for mature grasp on either legibility or speed. Pencil grasp patterns did not influence handwriting speed or legibility in this sample of typically developing children. This finding adds to the mounting body of evidence that alternative grasps may be acceptable for fast and legible handwriting. Copyright © 2012 by the American Occupational Therapy Association, Inc.

Judi Dench's age-inappropriateness and the role of M: challenging normative temporality.

2014-04-01

This article approaches Judi Dench's role as M in the long-running James Bond series from a gender and ageing studies' perspective and explores this character's subversion of normative concepts of gender and temporality. Based on the assumption that cultural narratives shape our understanding of ageing, it examines how M disrupts prescribed age- and gender roles, presenting an alternative within films which otherwise perpetuate normative notions of a sexualised, youthful femininity. It focusses on Dench's return as M in Casino Royale (2006), as an instance of anachronism (Russo, 1999), subverting viewers' expectation of linear timelines and examines M's challenge of normative age-appropriateness in Skyfall (2012). Despite M's portrayal as a more vulnerable female character in the latter, this article presents her character as an alternative to traditional portrayals of older women on screen.

One of the major applications of the space station will be to act as a refueling depot for cryogenic-fueled space-based orbital transfer vehicles (OTV), Earth-storable fueled orbit maneuvering vehicles, and refurbishable satellite spacecraft using hydrazine. One alternative for fuel storage at the space station is a tethered orbital refueling facility (TORF), separated from the space station by a sufficient distance to induce a gravity gradient force that settles the stored fuels. The technical feasibility was examined with the primary focus on the refueling of LO2/LH2 orbital transfer vehicles. Also examined was the tethered facility on the space station. It was compared to a zero-gravity facility. A tethered refueling facility should be considered as a viable alternative to a zero-gravity facility if the zero-gravity fluid transfer technology, such as the propellant management device and no vent fill, proves to be difficult to develop with the required performance.

Many women would like to avoid pharmacological or invasive methods of pain management in labour and this may contribute towards the popularity of complementary methods of pain management. This review examined currently available evidence supporting the use of alternative and complementary therapies for pain management in labour. To examine the effectiveness of complementary and alternative therapies for pain management in labour on maternal and perinatal morbidity. The trials included three trials of hypnosis (n = 189), one involving audio-analgesia (n = 25), one involving (n = 22), and one trial of music (n = 30). Women receiving hypnosis were more satisfied with their pain management in labour compared with controls (RR 2.33, 95% CI 1.55 to 4.71). No differences were seen for women recieving, music or audio analgesia. Hypnosis may be beneficial for the management of pain during labour. However, few complementary therapies have been subjected to proper scientific study.
