Limited evidence exists on the comprehension and use of Nutrition Facts tables (NFt) among adolescents and young adults. This study provides an account of how young people engage with, understand, and apply nutrition information on the current and modified versions of the NFt to compare and choose foods. Participants aged 16-24 years (n = 26) were asked to "think aloud" while viewing either the current or 1 of 5 modified NFts and completing a behavioural task. The task included a questionnaire with 9 functional items requiring participants to define, compare, interpret, and manipulate serving size and percentage daily value (%DV) information on NFts. Semi-structured interviews were conducted to further probe thought processes and difficulties experienced in completing the task. Equal serving sizes on NFts improved ability to accurately compare nutrition information between products. Most participants could define %DV and believed it can be used to compare foods, yet some confusion persisted when interpreting %DVs and manipulating serving-size information on NFts. Where serving sizes were unequal, mathematical errors were often responsible for incorrect responses. Results reinforce the need for equal serving sizes on NFts of similar products and highlight young Canadians' confusion when using nutrition information on NFts.

Self-Serving Bias or Simply Serving the Self? Evidence for a Dimensional Approach to Narcissism.

PubMed

Tamborski, Michael; Brown, Ryan P; Chowning, Karolyn

2012-06-01

Previous research has suggested that narcissism can be conceptualized as a multidimensional construct consisting of the related, but unique, dimensions of grandiosity and entitlement. The current studies examined the divergent associations of grandiosity and entitlement with respect to different types of self-serving strategies. In Study 1, we found that narcissistic grandiosity, but not entitlement, was positively associated with a self-enhancing strategy of unrealistic optimism. This association was not mediated by self-esteem. In Study 2, narcissistic entitlement, but not grandiosity, was predictive of unethical decision-making, an interpersonal self-promotional strategy that advances the self at the expense of others. Together, both studies support a model of narcissism consisting of a relatively intrapersonal dimension of grandiosity and a relatively interpersonal dimension of entitlement.

Physiological studies of the brain: Implications for science teaching

NASA Astrophysics Data System (ADS)

Esler, William K.

Physiological changes resulting from repeated, long-term stimulation have been observed in the brains of both humans and laboratory animals. It may be speculated that these changes are related to short-term and long-term memory processes. A physiologically based model for memory processing (PBMMP) can serve to explain the interrelations of various areas of the brain as they process new stimuli and recall past events. The model can also serve to explain many current principles of learning theory and serve as a foundation for developing new theories of learning based upon the physiology of the brain.

Many Vietnam-era women veterans served in or near war zones and may have experienced stressful or traumatic events during their service. Although posttraumatic stress disorder (PTSD) is well studied among men who served in Vietnam, no major epidemiologic investigation of PTSD among women has been performed. To assess (1) the onset and prevalence of lifetime and current PTSD for women who served during the Vietnam era, stratified by wartime location (Vietnam, near Vietnam, or the United States), and (2) the extent to which wartime location was associated with PTSD, with adjustment for demographics, service characteristics, and wartime exposures. Survey of 8742 women who were active-duty military personnel in the US Armed Forces at any time from July 4, 1965, through March 28, 1973, and alive as of survey receipt as part of Department of Veterans Affairs Cooperative Study 579, HealthVIEWS. Data were obtained from mailed and telephone surveys from May 16, 2011, through August 5, 2012, and analyzed from June 26, 2013, through July 30, 2015. Lifetime and current PTSD as measured by the PTSD module of the Composite International Diagnostic Interview, version 3.0; onset of PTSD; and wartime experiences as measured by the Women's Wartime Exposure Scale-Revised. Among the 4219 women (48.3%) who completed the survey and a telephone interview, the weighted prevalence (95% CI) of lifetime PTSD was 20.1% (18.3%-21.8%), 11.5% (9.1%-13.9%), and 14.1% (12.4%-15.8%) for the Vietnam, near-Vietnam, and US cohorts, respectively. The weighted prevalence (95% CI) of current PTSD was 15.9% (14.3%-17.5%), 8.1% (6.0%-10.2%), and 9.1% (7.7%-10.5%) for the 3 cohorts, respectively. Few cases of PTSD among the Vietnam or near-Vietnam cohorts were attributable to premilitary onset (weighted prevalence, 2.9% [95% CI, 2.2%-3.7%] and 2.9% [95% CI, 1.7%-4.2%], respectively). Unadjusted models for lifetime and current PTSD indicated that women who served in Vietnam were more likely to meet PTSD criteria than women who mainly served in the United States (odds ratio [OR] for lifetime PTSD, 1.53 [95% CI, 1.28-1.83]; OR for current PTSD, 1.89 [95% CI, 1.53-2.33]). When we adjusted for wartime exposures, serving in Vietnam or near Vietnam did not increase the odds of having current PTSD (adjusted ORs, 1.05 [95% CI, 0.75-1.46] and 0.77 [95% CI, 0.52-1.14], respectively). The prevalence of PTSD for the Vietnam cohort was higher than previously documented. Vietnam service significantly increased the odds of PTSD relative to US service; this effect appears to be associated with wartime exposures, especially sexual discrimination or harassment and job performance pressures. Results suggest long-lasting mental health effects of Vietnam-era service among women veterans.

Cohn, Elizabeth Gross; Larson, Elaine L; Araujo, Christina; Sawyer, Vanessa; Williams, Olajide

2012-08-01

Current strategies for combating obesity include recent federal legislation mandating calorie count postings in chain restaurants. This study describes the current practice of menu board calorie postings in a low-income urban neighborhood, identifies the extent to which current practice complies with existing policy, and evaluates the practical utility of menu boards to consumers. We conclude that although most postings were legally compliant, they did not demonstrate utility. Menu postings for individual servings are easily understood, but complex math skills are needed to interpret meals designed to serve more than one person. In some items, calories doubled depending on flavor and the calorie posting did not give enough information to make healthier selections. We identified specific strategies to improve practical utility and provide recommendations for policy implementation.

Increased neural and pupillary reactivity to emotional faces in adolescents with current and remitted major depressive disorder.

2017-05-01

This study combined multiple levels of analysis to examine whether disrupted neural and pupillary reactivity to emotional faces serves as a state- or trait-like marker of adolescent major depressive disorder (MDD). The study examined differences in pupil dilation and the event-related potential (ERP) late positive potential (LPP) component to emotional faces before and after a negative mood induction between 71 adolescents (age 11-18 years) with (i) a current diagnosis of MDD, (ii) a past episode of MDD currently in full remission and (iii) no lifetime history of any Axis I disorder. Relative to healthy control (HC) youth, adolescents with current or remitted MDD exhibited an enhanced LPP and pupillary response to all emotional facial expressions (fearful, happy and sad). This difference in reactivity between remitted depressed and HC adolescents persisted following the negative mood induction. Results also revealed that LPP and pupillary responses to emotional faces were significantly related, but only among the currently depressed adolescents. This study suggests that increased physiological and neural activation in response to social-emotional stimuli may not only characterize currently depressed adolescents, but also remains following MDD remission, potentially serving as a mechanism of risk for future depression relapse. © The Author (2017).

Systematic evaluation and validation of new prognostic and predictive markers, technologies and interventions for colorectal cancer (CRC) is crucial for optimizing patients' outcomes. With only 5-15% of patients participating in clinical trials, generalizability of results is poor. Moreover, current trials often lack the capacity for post-hoc subgroup analyses. For this purpose, a large observational cohort study, serving as a multiple trial and biobanking facility, was set up by the Dutch Colorectal Cancer Group (DCCG). The Prospective Dutch ColoRectal Cancer cohort is a prospective multidisciplinary nationwide observational cohort study in the Netherlands (yearly CRC incidence of 15 500). All CRC patients (stage I-IV) are eligible for inclusion, and longitudinal clinical data are registered. Patients give separate consent for the collection of blood and tumor tissue, filling out questionnaires, and broad randomization for studies according to the innovative cohort multiple randomized controlled trial design (cmRCT), serving as an alternative study design for the classic RCT. Objectives of the study include: 1) systematically collected long-term clinical data, patient-reported outcomes and biomaterials from daily CRC practice; and 2) to facilitate future basic, translational and clinical research including interventional and cost-effectiveness studies for both national and international research groups with short inclusion periods, even for studies with stringent inclusion criteria. Seven months after initiation 650 patients have been enrolled, eight centers participate, 15 centers await IRB approval and nine embedded cohort- or cmRCT-designed studies are currently recruiting patients. This cohort provides a unique multidisciplinary data, biobank, and patient-reported outcomes collection initiative, serving as an infrastructure for various kinds of research aiming to improve treatment outcomes in CRC patients. This comprehensive design may serve as an example for other tumor types.

Accurate estimation of food portion size is a difficult task. Visual cues are important mediators of portion size and therefore technology-based aids may assist consumers when serving and estimating food portions. The current study evaluated the usability and impact on estimation error of standard food servings of a novel augmented reality food serving aid, ServAR. Participants were randomised into one of three groups: 1) no information/aid (control); 2) verbal information on standard serving sizes; or 3) ServAR, an aid which overlayed virtual food servings over a plate using a tablet computer. Participants were asked to estimate the standard serving sizes of nine foods (broccoli, carrots, cauliflower, green beans, kidney beans, potato, pasta, rice, and sweetcorn) using validated food replicas. Wilcoxon signed-rank tests compared median served weights of each food to reference standard serving size weights. Percentage error was used to compare the estimation of serving size accuracy between the three groups. All participants also performed a usability test using the ServAR tool to guide the serving of one randomly selected food. Ninety adults (78.9% female; a mean (95%CI) age 25.8 (24.9-26.7) years; BMI 24.2 (23.2-25.2) kg/m 2 ) completed the study. The median servings were significantly different to the reference portions for five foods in the ServAR group, compared to eight foods in the information only group and seven foods for the control group. The cumulative proportion of total estimations per group within ±10%, ±25% and ±50% of the reference portion was greater for those using ServAR (30.7, 65.2 and 90.7%; respectively), compared to the information only group (19.6, 47.4 and 77.4%) and control group (10.0, 33.7 and 68.9%). Participants generally found the ServAR tool easy to use and agreed that it showed potential to support optimal portion size selection. However, some refinements to the ServAR tool are required to improve the user experience. Use of the augmented reality tool improved accuracy and consistency of estimating standard serve sizes compared to the information only and control conditions. ServAR demonstrates potential as a practical tool to guide the serving of food. Further evaluation across a broad range of foods, portion sizes and settings is warranted.

Solar activity and economic fundamentals: Evidence from 12 geographically disparate power grids

Forbes, Kevin F.; St. Cyr, O. C.

2008-10-01

This study uses local (ground-based) magnetometer data as a proxy for geomagnetically induced currents (GICs) to address whether there is a space weather/electricity market relationship in 12 geographically disparate power grids: Eirgrid, the power grid that serves the Republic of Ireland; Scottish and Southern Electricity, the power grid that served northern Scotland until April 2005; Scottish Power, the power grid that served southern Scotland until April 2005; the power grid that serves the Czech Republic; E.ON Netz, the transmission system operator in central Germany; the power grid in England and Wales; the power grid in New Zealand; the power grid that serves the vast proportion of the population in Australia; ISO New England, the power grid that serves New England; PJM, a power grid that over the sample period served all or parts of Delaware, Maryland, New Jersey, Ohio, Pennsylvania, Virginia, West Virginia, and the District of Columbia; NYISO, the power grid that serves New York State; and the power grid in the Netherlands. This study tests the hypothesis that GIC levels (proxied by the time variation of local magnetic field measurements (dH/dt)) and electricity grid conditions are related using Pearson's chi-squared statistic. The metrics of power grid conditions include measures of electricity market imbalances, energy losses, congestion costs, and actions by system operators to restore grid stability. The results of the analysis indicate that real-time market conditions in these power grids are statistically related with the GIC proxy.

Definition of the Mediterranean Diet; a Literature Review.

Davis, Courtney; Bryan, Janet; Hodgson, Jonathan; Murphy, Karen

2015-11-05

Numerous studies over several decades suggest that following the Mediterranean diet (MedDiet) can reduce the risk of cardiovascular disease and cancer, and improve cognitive health. However, there are inconsistencies among methods used for evaluating and defining the MedDiet. Through a review of the literature, we aimed to quantitatively define the MedDiet by food groups and nutrients. Databases PubMed, MEDLINE, Science Direct, Academic Search Premier and the University of South Australia Library Catalogue were searched. Articles were included if they defined the MedDiet in at least two of the following ways: (1) general descriptive definitions; (2) diet pyramids/numbers of servings of key foods; (3) grams of key foods/food groups; and (4) nutrient and flavonoid content. Quantity of key foods and nutrient content was recorded and the mean was calculated. The MedDiet contained three to nine serves of vegetables, half to two serves of fruit, one to 13 serves of cereals and up to eight serves of olive oil daily. It contained approximately 9300 kJ, 37% as total fat, 18% as monounsaturated and 9% as saturated, and 33 g of fibre per day. Our results provide a defined nutrient content and range of servings for the MedDiet based on past and current literature. More detailed reporting amongst studies could refine the definition further.

Increasing fruits and vegetables in midlife women: a feasibility study.

Gunn, Caroline A; Weber, Janet L; Coad, Jane; Kruger, Marlena C

2013-07-01

The positive link between bone health and fruit/vegetable consumption has been attributed to the lower renal acid load of a diet high in alkaline-forming fruit/vegetables. Other important dietary determinants of bone health include micronutrients and bioactives found in fruit/vegetables. We hypothesized that increased intake of fruit/vegetables to 9 or more servings a day would lower net endogenous acid production (NEAP) significantly (~20 mEq/d) and increase urine pH (0.5 pH units). This 8-week feasibility study investigated if 21 midlife women (age, 40-65 years) currently consuming 5 or less servings a day of fruit/vegetables could increase their intake to 9 or more servings a day to substantially lower NEAP and include specific vegetables daily. Three-day diet diaries were completed at baseline and the end of the study and assessed for NEAP (estimated) and number of servings from all food groups. Urine pH dipsticks were provided for the participants to assess and record their fasting urine pH daily (second void). Seventy-six percent of women achieved the study aim, which was to increase to 9 or more servings of fruit/vegetables for at least 5 d/wk. There was a reduction in the number of bread/cereal servings. Net endogenous acid production (estimated) was reduced significantly, with a mean urine pH increase of 0.68 pH units (95% confidence interval, 0.46-1.14); however, daily urine pH measures showed high variability. This study demonstrated that a group of midlife women can change their diet for 8 weeks by significantly increasing fruit/vegetable servings and include specific "bone friendly" vegetables daily, resulting in a significant decrease in estimated dietary NEAP and an increase in urine pH.

Career dissatisfaction among occupational physicians (OP) may affect their performance and the quality of healthcare services provided. Our study aims to assess the job satisfaction of OP serving on the Institutes for Occupational Safety and Health(IOSH) in Tunisia and to identify the determinant factors. We conducted a national cross-sectional validated SAPHORA JOB survey among all the OP serving on 22 IOSH. 58% of OP serving on the IOSH were dissatisfied with their career. Career satisfaction was statistically influenced by the number of healthcare facilities for which they were responsible (p=0.016), the work organisation (p=0.010), the work impact (p=0.011), the salary (p‹10-3) and knowledge on current regulation (p=0.047). The standardisation of pay scale and career ladders for OP serving on the IOSH based on a revision of legislative texts is recommended. Improving organization and working conditions may allow success in the workplace and benefit enhancement.

Given the proposed changes to nutrition labelling in Canada and the dearth of research examining comprehension and use of nutrition facts tables (NFts) by adolescents and young adults, our objective was to experimentally test the efficacy of modifications to NFts on young Canadians' ability to interpret, compare and mathematically manipulate nutrition information in NFts on prepackaged food. An online survey was conducted among 2010 Canadians aged 16 to 24 years drawn from a consumer sample. Participants were randomized to view two NFts according to one of six experimental conditions, using a between-groups 2 x 3 factorial design: serving size (current NFt vs. standardized serving-sizes across similar products) x percent daily value (% DV) (current NFt vs. "low/med/high" descriptors vs. colour coding). The survey included seven performance tasks requiring participants to interpret, compare and mathematically manipulate nutrition information on NFts. Separate modified Poisson regression models were conducted for each of the three outcomes. The ability to compare two similar products was significantly enhanced in NFt conditions that included standardized serving-sizes (p ≤ .001 for all). Adding descriptors or colour coding of % DV next to calories and nutrients on NFts significantly improved participants' ability to correctly interpret % DV information (p ≤ .001 for all). Providing both standardized serving-sizes and descriptors of % DV had a modest effect on participants' ability to mathematically manipulate nutrition information to calculate the nutrient content of multiple servings of a product (relative ratio = 1.19; 95% confidence limit: 1.04-1.37). Standardizing serving-sizes and adding interpretive % DV information on NFts improved young Canadians' comprehension and use of nutrition information. Some caution should be exercised in generalizing these findings to all Canadian youth due to the sampling issues associated with the study population. Further research is needed to replicate this study in a more heterogeneous sample in Canada and across a range of food products and categories.

Aragones, Abraham; Trinh-Shevrin, Chau; Gany, Francesca

2012-01-01

Chinese immigrants in the United States are broadly affected by cancer health disparities. We examined the cancer screening attitudes and practices of physicians serving Chinese immigrants in the New York City (NYC) area by mailing a cancer screening survey, based on current guidelines, to a random sample of physicians serving this population. Fifty three physicians (44%) completed the survey. Seventy-two percent reported following the guidelines for breast cancer, 35% for cervical cancer screening, and 45% for all colorectal cancer screening tests. Sixty-eight percent of physicians were satisfied with their current rates of cancer screening with their Chinese immigrant patient population. Physicians serving the Chinese community in NYC follow cancer screening guidelines inadequately. Cancer screening rates in this population could likely be increased by interventions that target physicians and improve awareness of guidelines and recommended best practices. PMID:19202247

2012-08-01

The purpose of the current study was to determine the obesogenic practices in all-day child-care centers caring for preschool-aged children. This study used a cross-sectional, self-reported survey mailed to centers across Oklahoma (n=314). Frequency of responses and χ(2) were calculated comparing region and star rating. Items where the majority of centers frequently report best practices include: daily fruits served (76%), daily nonfried vegetables served (71%), rarely/never served sugary drinks (92%), rarely/never used food to encourage good behaviors (88%), staff join children at table most of the time (81%), staff rarely eat different foods in view of children (69%), visible self-serve or request availability of water (93%), regular informal communication about healthy eating (86%), opportunities for outdoor play (95%), not withholding activity for punishment (91%), accessible play equipment (59% to 80% for different types of equipment), and minimization of extended sitting time (78%). Practices where centers can improve include increasing variety of vegetables (18%), reducing frequency of high-fat meats served (74% serve more than once per week), increasing high-fiber and whole-grain foods (35% offer daily), serving style of "seconds" (28% help kids determine whether they are still hungry), nonfood holiday celebrations (44% use nonfood treats), having toys and books that encourage healthy eating (27%) and physical activity (25%) in all rooms in the center, a standard nutrition (21%) and physical education (50%) curriculum, and following a written physical activity policy (43%). Practitioners can use these data to develop benchmarks and interventions, as this was the first study to assess statewide obesogenic practices in child care.

Proteomics of the Human Placenta: Promises and Realities

Robinson, J.M.; Ackerman, W.E.; Kniss, D.A.; Takizawa, T.; Vandré, D.D.

2015-01-01

Proteomics is an area of study that sets as its ultimate goal the global analysis of all of the proteins expressed in a biological system of interest. However, technical limitations currently hamper proteome-wide analyses of complex systems. In a more practical sense, a desired outcome of proteomics research is the translation of large protein data sets into formats that provide meaningful information regarding clinical conditions (e.g., biomarkers to serve as diagnostic and/or prognostic indicators of disease). Herein, we discuss placental proteomics by describing existing studies, pointing out their strengths and weaknesses. In so doing, we strive to inform investigators interested in this area of research about the current gap between hyperbolic promises and realities. Additionally, we discuss the utility of proteomics in discovery-based research, particularly as regards the capacity to unearth novel insights into placental biology. Importantly, when considering under studied systems such as the human placenta and diseases associated with abnormalities in placental function, proteomics can serve as a robust ‘shortcut’ to obtaining information unlikely to be garnered using traditional approaches.

1988-09-02

This study investigates whether military records can be used to identify US Army Vietnam veterans who were likely to be exposed to the herbicide Agent Orange. Serum levels of 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD), a toxic contaminant in Agent Orange, were obtained for 646 ground combat troops who served in heavily sprayed areas of Vietnam and for 97 veterans who did not serve in Vietnam. The distributions of current TCDD levels in Vietnam and non-Vietnam veterans were nearly identical (mean in each group, approximately equal to 4 parts per trillion (ppt)). Only two men (both Vietnam veterans) had clearly elevated levels (greater thanmore » 20 ppt). Levels of TCDD did not tend to increase with greater likelihood of exposure to Agent Orange, as estimated from either military records or self-reported exposure. This study is consistent with other studies and suggests that most US Army ground troops who served in Vietnam were not heavily exposed to TCDD, except perhaps men whose jobs involved handling herbicides.« less

2017-01-01

Cryo-EM in structural biology is currently served by three public archives – EMDB for 3DEM reconstructions, PDB for models built from 3DEM reconstructions and EMPIAR for the raw 2D image data used to obtain the 3DEM reconstructions. These archives play a vital role for both the structural community and the wider biological community in making the data accessible so that results may be reused, reassessed and integrated with other structural and bioinformatics resources. The important role of the archives is underpinned by the fact that many journals mandate the deposition of data to PDB and EMDB on publication. The field is currently undergoing transformative changes where on the one hand high-resolution structures are becoming a routine occurrence while on the other hand electron tomography is enabling the study of macromolecules in the cellular context. Concomitantly the archives are evolving to best serve their stakeholder communities. In this chapter we describe the current state of the archives, resources available for depositing, accessing, searching, visualising and validating data, on-going community-wide initiatives and opportunities and challenges for the future.

Achieving End-to-End QoS in the Next Generation Internet: Integrated Services Over Differentiated Service Networks

NASA Technical Reports Server (NTRS)

Bai, Haowei; Atiquzzaman, Mohammed; Ivancic, William

2001-01-01

Currently there are two approaches to provide Quality of Service (QoS) in the next generation Internet: An early one is the Integrated Services (IntServ) with the goal of allowing end-to-end QoS to be provided to applications; the other one is the Differentiated Services (DiffServ) architecture providing QoS in the backbone. In this context, a DiffServ network may be viewed as a network element in the total end-to-end path. The objective of this paper is to investigate the possibility of providing end-to-end QoS when IntServ runs over DiffServ backbone in the next generation Internet. Our results show that the QoS requirements of IntServ applications can be successfully achieved when IntServ traffic is mapped to the DiffServ domain in next generation Internet.

Joshi, Parth; Vyas, Meet; Patel, Chirag

2018-05-01

Activated porous carbons are made through pyrolysis and activation of carbonaceous natural as well as synthetic precursors. The use of low-cost activated carbon derived from azadirachta indica, an agricultural waste material, has been investigated as a replacement for the current expensive methods of removing nickel ions from wastewater. The temperature variation study showed that the nickel ions adsorption is endothermic and spontaneous with increased randomness at the solid solution interface. Significant effect on adsorption was observed on varying the pH of the nickel ion solutions. Therefore, this study revealed that azadirachta indica can serve as a good source of activated carbon with multiple and simultaneous metal ions removing potentials and may serve as a better replacement for commercial activated carbons in applications that warrant their use.

Social adversities in first-time and repeat prisoners.

2008-11-01

To explore possible systematic differences between prison inmates serving their first sentence and inmates having experienced previous incarcerations. It is hoped that a better knowledge of these issues will make us better equipped to meet the rehabilitation needs of our prisoners and decrease their risk of reoffending and reincarceration. In this cross-sectional study a randomly selected and nationally representative sample of 260 Norwegian prisoners, 100 serving their first sentence and 160 recidivists, was interviewed with special focus on childhood circumstances, education, work experience, and present social and economic situation. In addition their criminal records were collected from the National Crime Registry. In males multivariate analyses identified a number of variables independently and significantly associated with being a repeat offender. The odds for reincarceration increased significantly if the person fulfilled any one of the following criteria: having experienced the incarceration of a family member during childhood (OR = 3.6); having experienced childcare interventions during childhood (OR = 3.2); current drug abuse (OR = 2.6); current housing problems (OR = 2.3). In females only one strong correlation emerged: if the person had current drug problems the odds for being a recidivist increased substantially (OR = 10.9). While criminal reoffending and reincarceration seemed to be primarily associated with drug abuse in females, the childhood problems of male repeat offenders, compared with males serving their first sentence, indicate that these individuals' current multiple social and economic disadvantages were complex in origin and of long standing. Interventions aimed at preventing reoffending must take into account the gender differences demonstrated. ing at primary prevention, the negative effects associated with parental incarceration are crucial: how can one prevent the perpetuation of these problems from one generation to the next?

2017-01-01

Family meals have been associated with higher diet quality and reduced risk of obesity in children. Observational studies of the family meal have been employed with increasing frequency, yet there is currently no tool available for measuring the healthfulness of food served during the meal. Here we present the development and validation of the Healthy Meal Index (HMI), a novel tool for scoring the healthfulness of foods served to children during a meal, as well as sociodemographic predictors of meal scores. Parents of 233 children, aged 4–8 years, self-recorded three home dinners. A research assistant obtained a list of foods available during the meal (meal report) via phone call on the night of each video-recorded meal. This meal report was coded into component foods groups. Subsequently, meals were scored based on the availability of more healthy “Adequacy foods” and the absence of “Moderation foods”, (of which reduced consumption is recommended, according to pediatric dietary guidelines). Adjusted linear regression tested the association of sociodemographic characteristics with HMI scores. A validation study was conducted in a separate sample of 133 children with detailed meal data. In adjusted models, female children had higher HMI Moderation scores (p=0.02), but did not differ in HMI Adequacy or Total scores. Parents with more education served meals with higher HMI Adequacy (p=0.001) and Total scores (p=0.001), though no significant difference was seen in HMI Moderation score (p=0.21). The validation study demonstrated that the HMI was highly correlated with servings of foods and nutrients estimated from observations conducted by research staff. The HMI is a valuable tool for measuring the quality of meals served to children. PMID:26994739

In adjusted models, female children had higher HMI Moderation scores (p = 0.02), but did not differ in HMI Adequacy or Total scores. Parents with more education served meals with higher HMI Adequacy (p = 0.001) and Total scores (p = 0.001), though no significant difference was seen in HMI Moderation score (p = 0.21). The validation study demonstrated that the HMI was highly correlated with servings of foods and nutrients estimated from observations conducted by research staff. The HMI is a valuable tool for measuring the quality of meals served to children. Copyright © 2016. Published by Elsevier Ltd.

MicroRNAs in Leukemias: Emerging Diagnostic Tools and Therapeutic Targets

PubMed Central

Mian, Yousaf A.; Zeleznik-Le, Nancy J.

2010-01-01

MicroRNAs (miRNA) are small non-coding RNAs of ~22 nucleotides that regulate the translation and stability of mRNA to control different functions of the cell. Misexpression of miRNA has been linked to disruption of normal cellular functions, which results in various disorders including cancers such as leukemias. MicroRNA involvement in disease has been the subject of much attention and is increasing our current understanding of disease biology. Such linkages have been determined by high-throughput studies, which provide a framework for characterizing differential miRNA expression levels correlating to different cytogenetic abnormalities and their corresponding malignancies. In addition, functional studies of particular miRNAs have begun to define the effects of miRNA on predicted mRNA targets. It is clear that miRNAs can serve as molecular markers of leukemias and the hope is that they can also serve as new therapeutic targets. Studies are beginning to elucidate how to deliver therapeutic antagonists to attenuate overexpressed miRNAs and to replace underexpressed miRNAs. In this review, we: i) discuss the current understanding of miRNA function and expression in normal hematopoiesis, ii) provide examples of miRNAs that are misregulated in leukemias, and iii) evaluate the current status and potential future directions for the burgeoning field of antisense oligonucleotides and other therapeutic attempts to intervene in miRNA disregulation in leukemias.

Gomillion, Sarah C; Giuliano, Traci A

2011-01-01

The current investigation examined the influence of the media on gay, lesbian, and bisexual (GLB) identity using both survey and in-depth interview approaches. In Study 1, 126 GLB survey respondents (11 unreported) in Texas indicated that the media influenced their self-realization, coming out, and current identities by providing role models and inspiration. In Study 2, 15 interviewees (6 women and 9 men) revealed that media role models serve as sources of pride, inspiration, and comfort. Our findings suggest that increasing the availability of GLB role models in the media may positively influence GLB identity.

Weight gain rather than weight loss often occurs after breast cancer diagnosis despite breast cancer survivors frequently reported making healthful lifestyle changes. This study describes the prevalence and magnitude of changes in weight before and after breast cancer diagnosis and examines lifestyle behaviors of breast cancer survivors with stable weight, weight gain or weight loss. Respondents were 368 women with breast cancer characterized by stages I, II and III. All were recruited from hospitals or breast cancer support groups and had completed conventional treatment. Current weight and height were measured while weight at cancer diagnosis and 1 year before diagnosis were self-reported. Weight change was calculated as the difference between current weight and weight a year preceding breast cancer diagnosis. A 24-hour diet recall and Global Physical Activity Questionnaire assessed dietary intake and physical activity, respectively. Differences in lifestyle behaviors among weight change groups were examined using Analysis of Covariance (ANCOVA). Mean weight change from a year preceding diagnosis to study entry was 2.73 kg (95% CI: 1.90-3.55). Most women (63.3%) experienced weight gain rather than weight loss (36.7%) with a higher percentage (47.8%) having at least 5% weight gain (47.8%) rather than weight loss (22%), respectively. Compared to other weight change groups, women in >10% weight gain group had the lowest fruit and vegetable servings (1.58 servings/day; 95% CI: 1.36-1.82) and highest servings of dairy products (0.41 servings/day; 95% CI: 0.30-0.52). Weight gain was evident in this sample of women after breast cancer diagnosis. Information on magnitude of weight change after breast cancer diagnosis and lifestyle behaviors of breast cancer survivors with varying degrees of weight change could facilitate the development and targeting of effective intervention strategies to achieve healthy weight and optimal health for better survival.

The RTL-46: A simulated commercial air transportation study

NASA Technical Reports Server (NTRS)

Dunbar, Christian; Prette, John; Andersen, Gerald; Sprunck, Martin; Vogel, Christine; Rivera, Francisco

1993-01-01

The RTL-46 provides an aircraft which utilizes advanced technology within the fictional Aeroworld market to better service the air travel customers and airlines of Aeroworld. The RTL-46 is designed to serve the portion of the travel market which flies less than 10,000 feet per flight. The design cruise velocity for the aircraft is 35 ft/sec, which rapidly expedites travel through Aeroworld. The major focus of the endeavor was to design an aircraft which would serve the Aeroworld market better than the existing aircraft, the HB-40. This could have been done through targeting another portion of the Aeroworld market or through serving the current HB-40 market more effectively. Due to the fact that approximately 70 percent of the potential Aeroworld passengers desired flights of 10,000 ft or less, this range became the target market for the RTL-46.

Self-esteem, self-serving cognitions, and health risk behavior.

PubMed

Gerrard, M; Gibbons, F X; Reis-Bergan, M; Russell, D W

2000-12-01

The current article reviews prospective and experimental research on the relation between self-esteem and perceptions of vulnerability. These studies demonstrate that individuals with high self-esteem who engage in risk behavior often utilize a variety of self-serving cognitive strategies that protect them from fully acknowledging their vulnerability to the potential negative consequences of their behavior; e.g., they minimize their estimates of personal risk and overestimate the prevalence of the risk behavior among their peers. The article also provides data on an additional self-serving cognitive strategy employed by adolescents with high self-esteem--alteration of perceptions of others' reactions to their own risk behavior. Finally, the article reviews the emerging literature on the relation between these cognitive strategies and maladaptive health behavior, and proposes that whether these strategies are maladaptive depends on the nature of the threat and the availability of opportunities to engage in compensatory self-enhancement.

Music therapy services for individuals with autism spectrum disorder: a survey of clinical practices and training needs.

PubMed

Kern, Petra; Rivera, Nicole R; Chandler, Alie; Humpal, Marcia

2013-01-01

Over the past decade, the definitions, diagnoses, prevalence rates, theories about the causes, evidence-based treatment options, and practice guidelines pertaining to Autism Spectrum Disorder (ASD) have undergone numerous changes. While several recent studies evaluate the effects of music therapy interventions for individuals with ASD, no current review reflects the latest music therapy practices and trends. The purpose of this study was to evaluate the status of music therapy practices for serving clients with ASD, the implementation of national ASD standards and guidelines, the awareness of recent developments, and training needs of music therapists. Professional members of the American Music Therapy Association who are working with individuals with ASD served as the sample for this national cross-sectional survey study (N = 328). A 45-item online questionnaire was designed and distributed through email and social media. Participants accessed the online survey through SurveyMonkey®. Findings suggest music therapy practices and services for individuals with ASD have shifted and now reflect a slightly higher percentage of caseload, a broader age range of clients, and a trend to serve clients in home and community settings. Most therapeutic processes align with recommended practices for ASD and incorporate several of the recognized evidence-based practices. Less understood or recognized are inclusion practices and latest developments in the field of ASD. Music therapists have a solid understanding of providing services for individuals with ASD, but would benefit from advanced online training and improved information dissemination to stay current with the rapidly changing aspects pertinent to this population. © 2013 by the American Music Therapy Association.

We present an X-ray source catalog obtained with XMM-Newton in the XMM-LSS region as part of the X-SERVS survey (XMM-SERVS-LSS), which aims to expand the parameter space of current X-ray surveys with medium-deep X-ray observations in multiple large fields with superb multiwavelength coverage. Within the 5 deg$^2$ XMM-SERVS-LSS field, we combine the 1.3 Ms XMM observations allocated at XMM AO-15 with archival data, and identified 5218 X-ray sources of which 2400 are new sources. We reach $1.2\\times10^{-15}$ erg s$^{-1} cm$^{-1}$ for 50\\% of the area, which is comparable to the XMM-COSMOS survey but with 2.5 times more sources. We also present multiwavelength identifications, basic photometric properties, and spectroscopic redshifts obtained from the literature. These data, combined with the existing data from COSMOS, will enable a wide range of science on AGN evolution, including studying SMBH growth across the full range of cosmic environments and minimizing cosmic variance.

Assessing patients' current stage of change toward 6 healthy behaviors related to diabetes control. Behaviors studied were smoking cessation (2) regular exercise; (3) consuming 5 servings or more of fruits and vegetables; (4) decreasing intake of refined sugar; (5) reducing saturated fat; and (6) self monitoring of blood glucose (SMBG). Stage of change (SOC) for several diabetes control-related behaviors was assessed for 737 patients with type 2 diabetes using a staging algorithm. Socio-demographic data were collected by a structured interview-based questionnaire. There was high degree of readiness toward consuming diets with less saturated fat and simple sugar. Very low degree of readiness was reported for self-monitoring of blood glucose on a regular bases and for practicing physical exercise. Half of the participants (50.9%) were in the precontemplation stage for consuming ≥5 servings of fruits and vegetables every day. Significant correlations were obtained between the degree of readiness for several behaviors (p<0.01). Age, gender, income and education were all related to the stage of change of the studied behaviors (p<0.01). Patients with diabetes in Jordan are still in the pre-action stages for practicing exercise, consuming 5 servings or more of fruit and vegetable, and self-monitoring of blood glucose. The current finding suggests a need for nutritional education and interventions to raise awareness of lifestyle factors influencing glycemic control among diabetics.

The Role of Parent Depressive Symptoms in Positive and Negative Parenting in a Preventive Intervention

PubMed Central

Forehand, Rex; Thigpen, Jennifer C.; Parent, Justin; Hardcastle, Emily J.; Bettis, Alexandra; Compas, Bruce E.

2012-01-01

This study examined the role of parent depressive symptoms as a mediator of change in behaviorally observed positive and negative parenting in a preventive intervention program. The purpose of the program was to prevent child problem behaviors in families with a parent who has current or a history of major depressive disorder. One hundred and eighty parents and one of their 9-to-15-year old children served as participants and were randomly assigned to a family group cognitive-behavioral (FGCB) intervention or a written information (WI) comparison condition. At two months after baseline, parents in the FGCB condition had fewer depressive symptoms than those in the WI condition and these symptoms served as a mediator for changes in negative, but not positive, parenting at 6 months after baseline. The findings indicate that parent depressive symptoms are important to consider in family interventions with a parent who has current or a history of depression. PMID:22612463

CONSERVB: A numerical method to compute soil water content and temperature profiles under a bare surface

NASA Technical Reports Server (NTRS)

Vanbavel, C. H. M.; Lascano, R. J.

1982-01-01

A comprehensive, yet fairly simple model of water disposition in a bare soil profile under the sequential impact of rain storms and other atmospheric influences, as they occur from hour to hour is presented. This model is intended mostly to support field studies of soil moisture dynamics by our current team, to serve as a background for the microwave measurements, and, eventually, to serve as a point of departure for soil moisture predictions for estimates based in part upon airborne measurements. The main distinction of the current model is that it accounts not only for the moisture flow in the soil-atmosphere system, but also for the energy flow and, hence, calculates system temperatures. Also, the model is of a dynamic nature, capable of supporting any required degree of resolution in time and space. Much critical testing of the sample is needed before the complexities of the hydrology of a vegetated surface can be related meaningfully to microwave observations.

Coverage and prior authorization of psychotropic drugs under Medicare Part D.

PubMed

Huskamp, Haiden A; Stevenson, David G; Donohue, Julie M; Newhouse, Joseph P; Keating, Nancy L

2007-03-01

This study examined formulary coverage and use of utilization management tools for three classes of psychotropic medications (antidepressants, antipsychotics, and anticonvulsants) among Medicare Part D prescription drug plans serving individuals dually eligible for the Medicare and Medicaid programs. Plans must cover "all or substantially all" molecules (distinct drugs) in these classes. Plans serving "dual eligibles" generally covered at least one formulation of all molecules in the three classes. However, certain product formulations were not covered by a number of plans, and use of prior authorization was common for a minority of plans. The effect of Part D will depend on the restrictiveness of the prior authorization and appeals processes, which is currently unknown.

Regulation of cytoplasmic mRNA decay

PubMed Central

Schoenberg, Daniel R.; Maquat, Lynne E.

2012-01-01

Discoveries made over the past 20 years highlight the importance of mRNA decay as a means to modulate gene expression and thereby protein production. Up until recently, studies focused largely on identifying cis-acting sequences that serve as mRNA stability or instability elements, the proteins that bind these elements, how the process of translation influences mRNA decay, and the ribonucleases that catalyze decay. Now, current studies have begun to elucidate how the decay process is regulated. This review examines our current understanding of how mammalian-cell mRNA decay is controlled by different signaling pathways and lays out a framework for future research. PMID:22392217

Complex expression and localization of inactivating Kv channels in cultured hippocampal astrocytes.

PubMed

Bekar, Lane K; Loewen, Matthew E; Cao, Kun; Sun, Xianfeng; Leis, Jerome; Wang, Rui; Forsyth, George W; Walz, Wolfgang

2005-03-01

Voltage-gated potassium channels are well established as critical for setting action potential frequency, membrane potential, and neurotransmitter release in neurons. However, their role in the "nonexcitable" glial cell type is yet to be fully understood. We used whole cell current kinetics, pharmacology, immunocytochemistry, and RT-PCR to characterize A-type current in hippocampal astrocyte cultures to better understand its function. Pharmacological analysis suggests that approximately 70, 10, and <5% of total A current is associated with Kv4, Kv3, and Kv1 channels, respectively. In addition, pharmacology and kinetics provide evidence for a significant contribution of KChIP accessory proteins to astrocytic A-channel composition. Localization of the Shaw Kv3.4 channel to astrocytic processes and the Shal Kv4.3 channel to soma suggest that these channels serve a specific function. Given this complex A-type channel expression pattern, we assessed the role of A currents in membrane voltage oscillations in response to current injections. Although TEA-sensitive delayed-rectifying currents are involved in the extent of repolarization, 4-AP-sensitive A currents serve to increase the rate. As in neurons, this effect may enable astrocytes to respond rapidly to high-frequency synaptic events. Our results indicate that hippocampal astrocytes in vitro express multiple A-type Kv channel alpha-subunits with accessory, possibly Ca(2+)-sensitive, cytoplasmic subunits that appear to be specifically localized to subcellular membrane compartments. Function of these channels remains to be determined in a physiological setting. However, this study suggests that they enable astrocytes to respond rapidly with membrane voltage oscillations to high-frequency incoming signals, possibly synchronizing astrocyte function to neuronal activity.

Stolle-McAllister, Kathy; Sto. Domingo, Mariano R.; Carrillo, Amy

2011-02-01

The Meyerhoff Scholarship Program (MSP) is widely recognized for its comprehensive approach of integrating students into the science community. The supports provided by the program aim to develop students, primarily Blacks, into scientists by offering them academic, social, and professional opportunities to achieve their academic and career goals. The current study allowed for a rich understanding of the perceptions of current Meyerhoff students and Meyerhoff alumni about how the program works. Three groups of MSP students were included in the study: (1) new Meyerhoff students participating in Summer Bridge ( n = 45), (2) currently enrolled Meyerhoff students ( n = 92), and (3) graduates of the MSP who were currently enrolled in STEM graduate studies or had completed an advanced STEM degree ( n = 19). Students described the importance of several key aspects of the MSP: financial support, the Summer Bridge Program, formation of Meyerhoff identity, belonging to the Meyerhoff family, and developing networks—all of which serve to integrate students both academically and socially.

The Meyerhoff Scholarship Program (MSP) is widely recognized for its comprehensive approach of integrating students into the science community. The supports provided by the program aim to develop students, primarily Blacks, into scientists by offering them academic, social, and professional opportunities to achieve their academic and career goals. The current study allowed for a rich understanding of the perceptions of current Meyerhoff students and Meyerhoff alumni about how the program works. Three groups of MSP students were included in the study: 1) new Meyerhoff students participating in Summer Bridge (n=45), 2) currently enrolled Meyerhoff students (n=92), and 3) graduates of the MSP who were currently enrolled in STEM graduate studies or had completed an advanced STEM degree (n=19). Students described the importance of several key aspects of the Meyerhoff Scholars Program: financial support, the Summer Bridge Program, formation of Meyerhoff identity, belonging to the Meyerhoff family, and developing networks - all of which serve to integrate students both academically and socially.

A fluorescent 2,7-dimethoxy-substituted calix[4]carbazole (1) is facilely synthesized. The spectral behaviors of both the guest-induced switchable conformation of 1 and its abilities serving as the stabilizer and molecular carrier of curcumin are investigated. UV-vis, fluorescence and NMR spectral results show that upon binding to curcumin, the 1,3-alternate conformation of 1 is converted to be the cone one. The relative high association constant (6.4 × 106 M- 1) of 1 binding to curcumin enables it to stabilize the curcumin, to suppress its degradation, and to sustainably deliver it into the EYPC vesicles within 20 h. Moreover, the cytotoxicity assay shows that 1 does not interfere the antiproliferative activities of curcumin. All these properties endow 1 the potential capability of serving as the molecular drug carrier. Our current result may pave the way looking for more efficient fluorescent calixcarbazoles and thereof spectral utilities.

To develop and test the effectiveness of a mobile-phone based ecological momentary intervention (EMI) to increase fruit and vegetable (FV) consumption in low-consuming young adults. A two-week randomised controlled trial of low-FV consuming young adults ages 18-25 years (n = 171) compared three conditions: ecological momentary intervention (EMI), fruit and vegetable intervention (FVI), and a diet-as-usual control (ANZCTRN12615000183583). Participants in the EMI condition were sent two targeted text messages a day for 13 days and were asked to increase daily FV consumption to at least five servings. These messages were designed, using the Health Action Process Approach, to address salient beliefs identified as effective in a preliminary focus group investigation. Participants in the FVI condition were provided two servings of FV a day (carrots, kiwifruit or oranges, and apples) to eat in addition to their current diet. Control participants ate their normal diet. Participants reported their daily servings of FV each evening during the study using a smartphone-delivered survey. Blood samples testing plasma vitamin C and total carotenoids were taken pre- and post-intervention as an objective biomarker of FV intake. Participants in the EMI and FVI conditions reported higher daily servings of FV - approximately +1 serving per day more compared to control (EMI = 3.7 servings/day; FVI = 3.7 servings/day; Control = 2.8 servings/day) and approximately +1.2 servings compared to baseline. Increases in objective biomarkers for the experimental conditions supported the validity of self-reported FV consumption. Our results provide initial proof of concept that EMI strategies (with minor financial assistance) are as effective as giving FV in increasing FV consumption in educated, low-consuming young adults.

Current population-based methods for assessing dietary intake, including food frequency questionnaires, food diaries, and 24-h dietary recall, are limited in their ability to objectively measure food intake. Digital photography has been identified as a promising addition to these techniques but has rarely been assessed in self-serve settings. We utilized digital photography to examine university students' food choices and consumption in a self-serve dining hall setting. Research assistants took pre- and post-photos of students' plates during lunch and dinner to assess selection (presence), servings, and consumption of MyPlate food groups. Four coders rated the same set of approximately 180 meals for inter-rater reliability analyses; approximately 50 additional meals were coded twice by each coder to assess intra-rater agreement. Inter-rater agreement on the selection, servings, and consumption of food groups was high at 93.5%; intra-rater agreement was similarly high with an average of 95.6% agreement. Coders achieved the highest rates of agreement in assessing if a food group was present on the plate (95-99% inter-rater agreement, depending on food group) and estimating the servings of food selected (81-98% inter-rater agreement). Estimating consumption, particularly for items such as beans and cheese that were often in mixed dishes, was more challenging (77-94% inter-rater agreement). Results suggest that the digital photography method presented is feasible for large studies in real-world environments and can provide an objective measure of food selection, servings, and consumption with a high degree of agreement between coders; however, to make accurate claims about the state of dietary intake in all-you-can-eat, self-serve settings, researchers will need to account for the possibility of diners taking multiple trips through the serving line.

The Hebephiliac: Pedophile or Teleiophiliac?

PubMed

Sea, Jonghan; Beauregard, Eric

2018-07-01

The current study aims to fill the gap on hebephile sex offenders by comparing them to a group of pedophile offenders as well as a group of teleiophile offenders. The focus of the study is to examine the victims' and offenders' characteristics, the crime characteristics, and the modus operandi used by a sample of 111 male sex assaults currently serving a sentence for sexual crimes in Korea. Looking at all the comparisons conducted, it seems that the hebephiliac is not more similar to the pedophile nor the teleiophiliac. He is in fact a mix of both. Aside from certain characteristics that make hebephiliacs different from the other two subtypes of sex offenders (e.g., sadism, travelling longer than 2 km to commit the crime, history of bipolar disorder), they mainly share characteristics of both groups. The current study uncovers very important differences that could prove useful for the management of these cases by the actors of the criminal justice system.

An audit of 'standard' (STD) and 'energy and protein fortified' (HEHP) meals from Meals on Wheels (MOW) South Australia's summer menu was conducted to evaluate the consistency, and serve size and nutrient contents, of their menu items. Twenty soups, 20 mains and 20 desserts from each of the STD and HEHP menus were prepared at the MOW South Australia's kitchen and delivered to three 'sham(dummy)-clients' over a 5-week period. Each meal component was weighed in triplicate, to the nearest gram, the variation within the serve weight was calculated, and the overall energy and protein content of each meal was determined using FoodWorks (Xyris Software, Highgate Hill, Queensland, Australia). On average, the variability for soups and mains was ≤6% and for desserts was ≤10% and although the measured serve sizes of the MOW meals were consistently smaller than prescribed serve size, the differences were minor. As a percentage of recommended daily intakes (RDIs) for adults aged over 60 years, we calculated that the STD meals contained 21-39% for energy and 42-63% for protein while the HEHP meals contained 29-55% for energy and 46-69% for protein. These findings demonstrate that MOW meals currently meet the voluntary meal guidelines for energy and protein.

Appraisal Support from Natural Mentors, Self-worth, and Psychological Distress: Examining the Experiences of Underrepresented Students Transitioning Through College.

PubMed

Hurd, Noelle M; Albright, Jamie; Wittrup, Audrey; Negrete, Andrea; Billingsley, Janelle

2018-05-01

The current study explored whether cumulative appraisal support from as many as five natural mentors (i.e., nonparental adults from youth's pre-existing social networks who serve a mentoring role in youth's lives) led to reduced symptoms of depression and anxiety via improved global self-worth among underrepresented college students. Participants in the current study included 340 college students (69% female) attending a 4-year, predominantly White institution of higher education. Participants were first-generation college students, students from economically disadvantaged backgrounds, and/or students from underrepresented racial/ethnic minority groups. Participants completed surveys during the Fall and Spring of their first year of college and in the Spring of their second and third years of college. Results of the structural equation model (including gender, race/ethnicity, and extraversion as covariates) indicated that greater total appraisal support from natural mentoring relationships predicted decreases in students' psychological distress via increases in self-worth (indirect effects assessed via boot-strapped confidence intervals; 95% CI). The strength of association between appraisal support and self-worth was not moderated by the proportion of academic natural mentors. Findings from the current study extend previous research by measuring multiple natural mentoring relationships and pinpointing supportive exchanges that may be of particular consequence for the promotion of healthy youth development. Institutional efforts to reinforce pre-existing natural mentoring relationships and encourage the onset of new natural mentoring relationships may serve to bolster the well-being and success of underrepresented students attending predominantly White universities.

2018-03-01

There has been little empirical investigation of the preferences of people living in aged care homes for food services. The aim of the present study was to elicit consumer preferences and their willingness to pay for food service in aged care homes. Current residents or their family members were invited to take part in the discrete choice experiment questionnaire administered via interview. Of the 109 eligible residents and 175 eligible family members approached for consent 121 (43%) participated, including 43 residents. Participant preferences were influenced by food taste, choice in relation to serving size, timing of meal selection, visual appeal, and additional cost. Participants indicated they would be willing to pay an additional $24 (US$18.42) per week for food which tasted excellent and $8 (US$6.14) per week to have choice in serving sizes. The study found that respondents were willing to pay a premium to receive food that met their expectations of taste, and for a high level of control over serving sizes, which has implications for the funding and provision of food and dining in long-term care in the future. © 2018 The Authors Nursing & Health Sciences Published by John Wiley & Sons Australia, Ltd.

Domestic Violence Offender Treatment and Multidisciplinary Treatment Teams: The Role of "Treatment" Victim Advocates.

PubMed

Richards, Tara N; Gover, Angela R

2018-03-01

In Colorado, "treatment victim advocates" (TVAs) serve alongside providers and probation/parole officers on "multidisciplinary treatment teams" (MTTs) to oversee domestic violence offender's treatment. Although this model provides an opportunity for victim safety concerns to be heard, the utility of using victim advocates as advisors regarding interventions for domestic violence offenders has yet to be studied. Using survey data and narrative responses from TVAs ( N = 37), the current study examines the challenges and opportunities TVAs face while serving on MTTs. Results suggest that, overall, TVAs are successful in communicating with other members of the MTT, are confident that their perspectives are valued in the offender decision-making process, and are able to provide a wide variety of services and referrals to the victims with whom they are engaged. Implications and recommendations for the Colorado model as well as correctional professionals managing domestic violence offenders internationally are presented and discussed.

Accurate methods of assessing food intake in infants are needed to assess the relationship between infant feeding practices and risk of childhood obesity. Current methods are either subjective or have limited ability for use beyond clinical research settings. To assess the accuracy of the RFPM to evaluate simulated milk intake including energy, macronutrient, and micronutrient intake compared to direct weighing within a controlled study. Individuals were recruited to prepare three 2 fl oz, 4 fl oz, 6 fl oz, and 8 fl oz servings of infant formula and to capture photographs at different stages of preparation (dry powdered formula, prepared formula, and liquid waste) using the SmartIntake® application. Gram weights of the bottles were obtained by the RFPM and direct weighing. Using the United States Department of Agriculture National Nutrient Database for Standard Reference, energy, macronutrient, and micronutrient values were generated from gram weights. Intake of formula prepared from powder measured by the RFPM was equivalent to weighed intake within 7.5% equivalence bounds among all servings and each serving size. The mean difference between methods varied among servings sizes with the RFPM underestimating intake by 1.6 ± 0.4 kcals in 2 fl oz servings, 4.8 ± 0.6 kcals in 4 fl oz servings, and 6.2 ± 1.0 kcals in 6 fl oz servings, and overestimating intake by 0.1 ± 1.2 kcals in 8 fl oz servings. Bland-Altman analysis showed that the RFPM overestimated intake at lower levels food intake and underestimated intake at higher levels. Considering photographs of only the prepared formula bottle and the bottle with formula waste to simulate ready-to-feed formula and human breast milk, intake estimated by the RFPM was equivalent to the directly weighed intake within 7.5% for all servings. The RFPM has higher accuracy than subjective methods and similar accuracy as compared to the objective methods in estimating simulated intake of milk and formula with lower burden to caregivers. The RFPM is a viable method for measuring intake in exclusively milk fed infants by caregivers in a controlled environment with potential for widespread use in research and clinical practice.

This objective of this study was a methodological analysis of the variety and diversity of dietary items and their different origins offered in institutional menus across four daycare centers serving low-income families in Guatemala City. Foods, as served in daycare centers, were used to explore and illustrate the different approaches to evaluating food quality. Foods served at daycare centers were analyzed for variety (number of different items) and diversity (using three food-classification systems). The weight and energy contributions for each meal were reported for animal, plant, mixed, or water; modern versus traditional foods; fortified versus non-fortified foods; and processed versus unprocessed foods. During 5 d of observation, three of the four daycare centers served 100% of the food groups of the current Guatemalan and international classification systems. In addition, the results showed the four daycare centers provided mainly traditional and non-fortified plant-based foods. However, although the traditional foods contributed more by weight, the modern foods contributed more energy. These findings showed that the "modern" foods served at daycare centers are energy dense compared with traditional foods. These daycare centers contributed to variety and diversity while serving mainly traditional, plant-based foods. Our analysis went beyond the simple existence (mention) of a food as consumed to weight in grams or calories to provide potentially new and useful perspectives for understanding how guidelines for healthful eating patterns can be promoted and assessed, not only in children or in institutions but across all age groups, and settings.

Good nutrition is essential for the physical development of adolescent athletes, however data on dietary intakes of adolescent rugby players are lacking. This study quantified and evaluated dietary intake in 87 elite male English academy rugby league (RL) and rugby union (RU) players by age (under 16 (U16) and under 19 (U19) years old) and code (RL and RU). Relationships of intakes with body mass and composition (sum of 8 skinfolds) were also investigated. Using 4-day diet and physical activity diaries, dietary intake was compared with adolescent sports nutrition recommendations and the UK national food guide. Dietary intake did not differ by code, whereas U19s consumed greater energy (3366 ± 658 vs. 2995 ± 774 kcal·day -1 ), protein (207 ± 49 vs. 150 ± 53 g·day -1 ) and fluid (4221 ± 1323 vs. 3137 ± 1015 ml·day -1 ) than U16s. U19s consumed a better quality diet than U16s (greater intakes of fruit and vegetables; 4.4 ± 1.9 vs. 2.8 ± 1.5 servings·day -1 ; nondairy proteins; 3.9 ± 1.1 vs. 2.9 ± 1.1 servings·day -1 ) and less fats and sugars (2.0 ± 1. vs. 3.6 ± 2.1 servings·day -1 ). Protein intake vs. body mass was moderate (r = .46, p < .001), and other relationships were weak. The findings of this study suggest adolescent rugby players consume adequate dietary intakes in relation to current guidelines for energy, macronutrient and fluid intake. Players should improve the quality of their diet by replacing intakes from the fats and sugars food group with healthier choices, while maintaining current energy, and macronutrient intakes.

A Paradoxical Effect of Presession Attention on Stereotypy: Antecedent Attention as an Establishing, Not an Abolishing, Operation

Roantree, Christina F; Kennedy, Craig H

2006-01-01

Previous studies have shown that presession attention for problem behavior can serve as an abolishing operation when attention functions as a positive reinforcer. In the current study, we show that the stereotypy of a child with severe disabilities was undifferentiated during standard analogue functional analysis conditions. However, when noncontingent presession attention was provided, stereotypy occurred for social attention as a positive reinforcer, suggesting that the antecedent manipulation functioned as an establishing operation.

The epigenetic basis for centromere identity.

PubMed

Panchenko, Tanya; Black, Ben E

2009-01-01

The centromere serves as the control locus for chromosome segregation at mitosis and meiosis. In most eukaryotes, including mammals, the location of the centromere is epigenetically defined. The contribution of both genetic and epigenetic determinants to centromere function is the subject of current investigation in diverse eukaryotes. Here we highlight key findings from several organisms that have shaped the current view of centromeres, with special attention to experiments that have elucidated the epigenetic nature of their specification. Recent insights into the histone H3 variant, CENP-A, which assembles into centromeric nucleosomes that serve as the epigenetic mark to perpetuate centromere identity, have added important mechanistic understanding of how centromere identity is initially established and subsequently maintained in every cell cycle.

The objectives of this study were to determine the prevalence of smoking, identify the effects of deployment on smoking behavior and risk factors for smoking, and determine the short-term health outcomes associated with smoking in Australian Defence Force (ADF) personnel. Participants were randomly sampled from ADF members who deployed to the Solomon Islands between 2003 and 2005 and from a nondeployed comparison group. In total, 435 of 995 (44%) eligible individuals completed the study questionnaires. The prevalence of current smoking was highest in those who had completed less formal education and those who served in the Navy. Nearly two-thirds (63%) of current or former smokers smoked more while on overseas deployment. Current smokers were more likely to report current wheeze, shortness of breath, and persistent cough compared with nonsmokers. The ADF should continue to address cigarette smoking through its health promotion and health review programs and implement activities to reduce cigarette smoking on deployment.

The Molecular Biology of Frog Virus 3 and other Iridoviruses Infecting Cold-Blooded Vertebrates

Chinchar, V. Gregory; Yu, Kwang H.; Jancovich, James K.

2011-01-01

Frog virus 3 (FV3) is the best characterized member of the family Iridoviridae. FV3 study has provided insights into the replication of other family members, and has served as a model of viral transcription, genome replication, and virus-mediated host-shutoff. Although the broad outlines of FV3 replication have been elucidated, the precise roles of most viral proteins remain unknown. Current studies using knock down (KD) mediated by antisense morpholino oligonucleotides (asMO) and small, interfering RNAs (siRNA), knock out (KO) following replacement of the targeted gene with a selectable marker by homologous recombination, ectopic viral gene expression, and recombinant viral proteins have enabled researchers to systematically ascertain replicative- and virulence-related gene functions. In addition, the application of molecular tools to ecological studies is providing novel ways for field biologists to identify potential pathogens, quantify infections, and trace the evolution of ecologically important viral species. In this review, we summarize current studies using not only FV3, but also other iridoviruses infecting ectotherms. As described below, general principles ascertained using FV3 served as a model for the family, and studies utilizing other ranaviruses and megalocytiviruses have confirmed and extended our understanding of iridovirus replication. Collectively, these and future efforts will elucidate molecular events in viral replication, intrinsic and extrinsic factors that contribute to disease outbreaks, and the role of the host immune system in protection from disease.

The Molecular Underpinnings of Centromere Identity and Maintenance

PubMed Central

Sekulic, Nikolina; Black, Ben E.

2012-01-01

Centromeres direct faithful chromosome inheritance at cell division but are not defined by a conserved DNA sequence. Instead, a specialized form of chromatin containing the histone H3 variant, CENP-A, epigenetically specifies centromere location. We discuss current models where CENP-A serves as the marker for the centromere during the entire cell cycle in addition to generating the foundational chromatin for the kinetochore in mitosis. Recent elegant experiments indicate that engineered arrays of CENP-A-containing nucleosomes are sufficient to serve as the site of kinetochore formation and for seeding centromeric chromatin that self-propagates through cell generations. Finally, recent structural and dynamic studies of CENP-A-containing histone complexes—before and after assembly into nucleosomes—provide models to explain underlying molecular mechanisms at the centromere.

Current evidence implies that differentiated bone marrow mesenchymal stem cells (BMMSCs) can act as progenitor cells and transdifferentiate across lineage boundaries. However, whether this unrestricted lineage has specificities depending on the stem cell type is unknown. Placental-derived mesenchymal stem cells (PDMSCs), an easily accessible and less invasive source, are extremely useful materials in current stem cell therapies. No studies have comprehensively analyzed the transition in morphology, surface antigens, metabolism and multilineage potency of differentiated PDMSCs after their dedifferentiation. In this study, we showed that after withdrawing extrinsic factors, adipogenic PDMSCs reverted to a primitive cell population and retained stem cell characteristics. The mitochondrial network during differentiation and dedifferentiation may serve as a marker of absent or acquired pluripotency in various stem cell models. The new population proliferated faster than unmanipulated PDMSCs and could be differentiated into adipocytes, osteocytes and hepatocytes. The cell adhesion molecules (CAMs) signaling pathway and extracellular matrix (ECM) components modulate cell behavior and enable the cells to proliferate or differentiate during the differentiation, dedifferentiation and redifferentiation processes in our study. These observations indicate that the dedifferentiated PDMSCs are distinguishable from the original PDMSCs and may serve as a novel source in stem cell biology and cell-based therapeutic strategies. Furthermore, whether PDMSCs differentiated into other lineages can be dedifferentiated to a primitive cell population needs to be investigated.

2009-03-01

The study of music perception and cognition is one of the oldest topics in experimental psychology. The last 20 years have seen an increased interest in understanding the functional neuroanatomy of music processing in humans, using a variety of technologies including fMRI, PET, ERP, MEG, and lesion studies. We review current findings in the context of a rich intellectual history of research, organized by the cognitive systems underlying different aspects of human musical behavior. We pay special attention to the perception of components of musical processing, musical structure, laterality effects, cultural issues, links between music and movement, emotional processing, expertise, and the amusias. Current trends are noted, such as the increased interest in evolutionary origins of music and comparisons of music and language. The review serves to demonstrate the important role that music can play in informing broad theories of higher order cognitive processes such as music in humans.

2016-01-01

This study is an exploratory analysis of how bar staff perceive their role in preventing sexual harassment and assault. In particular, through qualitative focus group interviews, this study explores bar staff's attitudes surrounding sexual harassment/assault, how they currently handle these situations, and their opinions regarding programs and policies that currently mandate responsibility. Six major themes emerged including their hesitation to discuss sexual violence, their unique position as a service provider, their lack of knowledge (but eagerness to learn), and their reliance on stereotypical scenarios of sexual violence and interventions. These findings are situated in a framework for understanding barriers to bystander intervention and implications for community-based bystander programs are discussed.

Current-driven dynamics of skyrmions stabilized in MnSi nanowires revealed by topological Hall effect

PubMed Central

Liang, Dong; DeGrave, John P.; Stolt, Matthew J.; Tokura, Yoshinori; Jin, Song

2015-01-01

Skyrmions hold promise for next-generation magnetic storage as their nanoscale dimensions may enable high information storage density and their low threshold for current-driven motion may enable ultra-low energy consumption. Skyrmion-hosting nanowires not only serve as a natural platform for magnetic racetrack memory devices but also stabilize skyrmions. Here we use the topological Hall effect (THE) to study phase stability and current-driven dynamics of skyrmions in MnSi nanowires. THE is observed in an extended magnetic field-temperature window (15–30 K), suggesting stabilization of skyrmions in nanowires compared with the bulk. Furthermore, we show in nanowires that under the high current density of 108–109 A m−2, the THE decreases with increasing current densities, which demonstrates the current-driven motion of skyrmions generating the emergent electric field in the extended skyrmion phase region. These results open up the exploration of skyrmions in nanowires for fundamental physics and magnetic storage technologies. PMID:26400204

Gonzalez, Laura

Latin math and science students represent a resilient, determined, and encouraging group of high achievers. This qualitative study presents the narratives of 10 Latin science and math teacher candidates currently attending Hispanic-Serving Institutions in California. Semi structured, in-depth interviews were conducted, where participants shared the challenges they experienced and the factors that contributed to their resilience. The Connor Davidson Resilience Scale CD-RISC was used to present resilience measures for each participant. This score is compared to a group of college students throughout the nation. The findings provide insight into the critical need for universities to examine institutional practices and efforts to support these high achievers who have already beaten tremendous odds by entering the halls of higher education.

Optimism about safety and group-serving interpretations of safety among pedestrians and cyclists in relation to road use in general and under low light conditions.

PubMed

King, M J; Wood, J M; Lacherez, P F; Marszalek, R P

2012-01-01

Drivers are known to be optimistic about their risk of crash involvement, believing that they are less likely to be involved in a crash than other drivers. However, little comparative research has been conducted among other road users. In addition, optimism about crash risk is conceptualised as applying only to an individual's assessment of his or her personal risk of crash involvement. The possibility that the self-serving nature of optimism about safety might be generalised to the group-level as a cyclist or a pedestrian, i.e., becoming group-serving rather than self-serving, has been overlooked in relation to road safety. This study analysed a subset of data collected as part of a larger research project on the visibility of pedestrians, cyclists and road workers, focusing on a set of questionnaire items administered to 406 pedestrians, 838 cyclists and 622 drivers. The items related to safety in various scenarios involving drivers, pedestrians and cyclists, allowing predictions to be derived about group differences in agreement with items based on the assumption that the results would exhibit group-serving bias. Analysis of the responses indicated that specific hypotheses about group-serving interpretations of safety and responsibility were supported in 22 of the 26 comparisons. When the nine comparisons relevant to low lighting conditions were considered separately, seven were found to be supported. The findings of the research have implications for public education and for the likely acceptance of messages which are inconsistent with current assumptions and expectations of pedestrians and cyclists. They also suggest that research into group-serving interpretations of safety, even for temporary roles rather than enduring groups, could be fruitful. Further, there is an implication that gains in safety can be made by better educating road users about the limitations of their visibility and the ramifications of this for their own road safety, particularly in low light. 2010 Elsevier Ltd.

Walter B. Cannon's World War I experience: treatment of traumatic shock then and now.

PubMed

Ryan, Kathy L

2018-06-01

Walter B. Cannon (1871-1945), perhaps America's preeminent physiologist, volunteered for service with the Army Expeditionary Force (AEF) during World War I. He initially served with Base Hospital No. 5, a unit made up of Harvard clinicians, before moving forward to the front lines to serve at a casualty clearing station run by the British. During his time there, he performed research on wounded soldiers to understand the nature and causes of traumatic shock. Subsequently, Cannon performed animal experimentation on the causes of traumatic shock in the London laboratory of Dr. William Bayliss before being assigned to the AEF Central Medical Laboratory in Dijon, France, where he continued his experimental studies. During this time, he also developed and taught a curriculum on resuscitation of wounded soldiers to medical providers. Although primarily a researcher and teacher, Cannon also performed clinical duties throughout the war, serving with distinction under fire. After the war, Cannon wrote a monograph entitled Traumatic Shock (New York: Appleton, 1923), which encapsulated the knowledge that had been gained during the war, both from direct observation of wounded soldiers, as well as laboratory experimentation on the causes and treatment of traumatic shock. In his monograph, Cannon elucidates a number of principles concerning hemorrhagic shock that were later forgotten, only to be "rediscovered" during the current conflicts in Iraq and Afghanistan. This paper summarizes Cannon's wartime experiences and the knowledge gained concerning traumatic shock during World War I, with a comparison of current combat casualty care practices and knowledge to that which Cannon and his colleagues understood a century ago.

American Military Veteran Entrepreneurs: A Comprehensive Profile of Demographic, Service History, and Psychosocial Characteristics.

2017-01-01

American military veterans are nearly twice as likely to be self-employed compared to non-veterans, and are majority owners in nine percent of all businesses nationwide. Despite their contribution to the broader economy and the potential for training programs to cultivate and foster successful self-employment and veteran-lead entrepreneurial ventures, research on veteran entrepreneurs remains limited. In order to gain a better understanding of the potential strengths and vulnerabilities of veteran entrepreneurs, the current study utilized data from a large, nationally representative sample to profile self-employed veterans (n=230) and compare them to veterans who work as employees (n=1,055) with respect to demographic, military service history, and psychosocial characteristics. Results indicated that self-employed veterans were older and more educated and more likely to utilize VA healthcare. Self-employed veterans were more likely to serve in Vietnam and to serve in the military for fewer years. No differences were noted in perceived military experience, level of combat exposure, or military branch served as a function of self-employment. Although reporting more lifetime traumas, self-employed veterans did not experience higher rates of current or lifetime psychopathology or lower perceived quality of life. Potential protective resilience-promoting factors may be associated with the higher levels of openness, extraversion, optimism, achievement-orientation (purpose in life), and greater need for autonomy and professional development observed among self-employed veterans. Moreover, self-employed veterans demonstrated higher levels of gratitude, community integration, and altruistic service to others. Findings have potential to inform human resources management strategies and vocational training and reintegration initiatives for veterans.

2013-09-01

To determine whether current job is a reasonable surrogate for usual job. Data from the 2010 National Health Interview Survey were utilized to determine concordance between current and usual jobs for workers employed within the past year. Concordance was quantitated by kappa values for both simple and detailed industry and occupational groups. Good agreement is considered to be present when kappa values exceed 60. Overall kappa values ± standard errors were 74.5 ± 0.5 for simple industry, 72.4 ± 0.5 for detailed industry, 76.3 ± 0.4 for simple occupation, 73.7 ± 0.5 for detailed occupation, and 80.4 ± 0.6 for very broad occupational class. Sixty-five of 73 detailed industry groups and 78 of 81 detailed occupation groups evaluated had good agreement between current and usual jobs. Current job can often serve as a reliable surrogate for usual job in epidemiologic studies.

Magnetic skyrmion is a topologically protected domain-wall structure at nanoscale, which could serve as a basic building block for advanced spintronic devices. Here, we propose a microwave field-driven skyrmionic device with the transistor-like function, where the motion of a skyrmion in a voltage-gated ferromagnetic nanotrack is studied by micromagnetic simulations. It is demonstrated that the microwave field can drive the motion of a skyrmion by exciting the propagating spin waves, and the skyrmion motion can be governed by a gate voltage. We also investigate the microwave current-assisted creation of a skyrmion to facilitate the operation of the transistor-like skyrmionic device on the source terminal. It is found that the microwave current with an appropriate frequency can reduce the threshold current density required for the creation of a skyrmion from the ferromagnetic background. The proposed transistor-like skyrmionic device operated with the microwave field and current could be useful for building future skyrmion-based circuits.

The current study examined whether overgeneral autobiographical memory (OGM) bias serves as a state-like marker of major depressive disorder (MDD) in adolescence or whether it would also be observed in currently nondepressed adolescents with a history of MDD. We examined differences in OGM to positive and negative cue words between adolescents (aged 11–18 years) with current MDD (n = 15), remitted MDD (n = 25), and no history of any depressive disorder (n = 25). Youth and their parents were administered a structured diagnostic interview and adolescents completed the autobiographical memory test. Compared to never depressed adolescents, adolescents with current or remitted MDD recalled less specific memories in response to positive and negative cue words. The difference between the two MDD groups was small and nonsignificant. These findings suggest that OGM is not simply a state-like marker in currently depressed adolescents, but is also evident in adolescents with remitted MDD, indicating that it may represent a trait-like vulnerability that increases risk for relapse.

Objective To determine whether current job is a reasonable surrogate for usual job. Methods Data from the 2010 National Health Interview Survey were utilized to determine concordance between current and usual jobs for workers employed within the past year. Concordance was quantitated by kappa values for both simple and detailed industry and occupational groups. Good agreement is considered to be present when kappa values exceed 60. Results Overall kappa values ± standard errors were 74.5 ± 0.5 for simple industry, 72.4 ± 0.5 for detailed industry, 76.3 ± 0.4 for simple occupation, 73.7 ± 0.5 for detailed occupation, and 80.4 ± 0.6 for very broad occupational class. Sixty-five of 73 detailed industry groups and 78 of 81 detailed occupation groups evaluated had good agreement between current and usual jobs. Conclusions Current job can often serve as a reliable surrogate for usual job in epidemiologic studies. PMID:23969506

Challenges to evidence use are well documented. Less well understood are the formal supports-e.g., technical infrastructure, inter-organizational relationships-organizations may put in place to help overcome these challenges. This study will identify supports for evidence use currently used by private child and family serving agencies delivering publicly funded behavioral health and/or human services; examine contextual, organizational, and managerial factors associated with use of such supports; and determine how identified supports affect evidence use by staff at multiple levels of the organization. We will use a sequential explanatory mixed methods design, with study activities occurring in two sequential phases: In phase 1, quantitative survey data collected from managers of private child and family serving agencies in six states (CA, IN, KY, MO, PA, and WI) and analyzed using both regression and qualitative comparative analysis (QCA) will identify organizational supports currently being used to facilitate evidence use and examine the contextual, organizational, and managerial factors associated with the use of such supports. In phase 2, data from phase 1 will be used to select a purposive sample of 12 agencies for in-depth case studies. In those 12 agencies, semi-structured interviews with key informants and managers, focus groups with frontline staff, and document analysis will provide further insight into agencies' motivation for investing in organizational supports for evidence use and the facilitators and barriers encountered in doing so. Semi-structured interviews with managers and focus groups with frontline staff will also assess whether and how identified supports affect evidence use at different levels of the organization (senior executives, middle managers, frontline supervisors, and frontline staff). Within- and between-case analyses supplemented by QCA will identify combinations of factors associated with the highest and lowest levels of staff evidence use. This study will inform efforts to improve sustainment, scale-up, and spread of evidence by providing insight into organizational and managerial strategies that facilitate evidence use, the contexts in which these strategies are most effective, and their effect on evidence use by staff at different levels of the organization.

Current approaches to develop skin equivalents often only include the epidermal and dermal components. Yet, full thickness skin includes the hypodermis, a layer below the dermis of adipose tissue containing vasculature, nerves and fibroblasts, necessary to support the epidermis and dermis. In the present study, we developed a full thickness skin equivalent including an epidermis, dermis and hypodermis that could serve as an in vitro model for studying skin development, disease or as a platform for consumer product testing as a means to avoid animal testing. The full thickness skin equivalent was easy to handle and was maintained in culture for greater than 14 days while expressing physiologically relevant morphologies of both the epidermis and dermis, as seen by keratin 10, collagen I and collagen IV expression. The skin equivalent produced glycerol and leptin, markers of adipose tissue metabolism. This work serves as a foundation for our understanding of some of the necessary factors needed to develop a stable, functional model of full-thickness skin. PMID:23161763

The effects of material and experiential discretionary purchases on consumer happiness: moderators and mediators.

Experiential purchases are differentiated from material purchases in terms of objective; experiential purchases serve the purpose of acquiring a life experience, while material purchases serve the purpose of acquiring an object. Research has demonstrated that experiential purchases are associated with more happiness than material purchases. The current study investigated two explanations for this relationship that focused on the how the purchase influenced the self and how the purchase influenced interpersonal relationships. In addition, the study explored whether social economic status would influence the strength of the relationship between the type of purchase and happiness. Participants were required to recall either a recent experiential or material purchase and rate their happiness with the purchase. Then participants completed scales designed to measure the purchase's impact on the self and interpersonal relationships. Last, participants completed a scale to measure social economic status. It was found that Impacts on the Self mediated the relationship between purchase type and happiness and Socioeconomic Status moderated the relationship.

Differences in how services are organized and delivered can contribute significantly to variation in outcomes experienced by children and families. However, few comparative studies identify the strengths and limitations of alternative delivery system configurations. The current study provides the first empirical typology of private agencies involved with the formal child welfare system. Data collected in 2011 from a national sample of private agencies were used to classify agencies into five distinct groups based on internal management capacity, service diversification, integration, and policy advocacy. Findings reveal considerable heterogeneity in the population of private child and family serving agencies. Cross-group comparisons suggest that differences in agencies' strategic and structural characteristics correlated with agency directors' perceptions of different pressures in their external environment. Future research can use this typology to better understand local service systems and the extent to which different agency strategies affect performance and other outcomes. Such information has implications for public agency contracting decisions and could inform system-level assessment and planning of services for children and families.

GAUSTEQ was a Germany-U.S. exchange program in nuclear theory whose purpose was to focus research efforts on QCD studies of hadrons and nuclei, centered around the current and future research programs of Jefferson Lab and the Gesellschaft fur Schwerionenforschung (GSI) in Germany. GAUSTEQ provided travel support for theoretical physicists at US institutions conducting collaborative research with physicists in Germany. GSI (with its Darmstadt and Helmholtz Institute Mainz braches) served as the German “hub” for visits of U.S. physicists, while Jefferson Lab served as the corresponding “hub” for visits of German physicists visiting U.S. institutions through the reciprocal GUSTEHP (German-US Theorymore » Exchange in Hadron Physics) program. GAUSTEQ was funded by the Office of Nuclear Physics of the U.S. Department of Energy, under Contract No.DE-SC0006758 and officially managed through Old Dominion University in Norfolk, Virginia. The program ran between 2011 and 2015.« less

The stromal and immune cells that form the tumor microenvironment serve a key role in the aggressiveness of tumors. Current tumor-centric interpretations of cancer transcriptome data ignore the roles of stromal and immune cells. The aim of the present study was to investigate the clinical utility of stromal and immune cells in tissue-based transcriptome data. The 'Estimation of STromal and Immune cells in MAlignant Tumor tissues using Expression data' (ESTIMATE) algorithm was used to probe diverse cancer datasets and the fraction of stromal and immune cells in tumor tissues was scored. The association between the ESTIMATE scores and patient survival data was asessed; it was indicated that the two scores have implications for patient survival, metastasis and recurrence. Analysis of a colorectal cancer progression dataset revealed that decreased levels immune cells could serve an important role in cancer progression. The results of the present study indicated that trasncriptome-derived stromal and immune scores may be a useful indicator of cancer prognosis.

2013-12-01

Consumer and public health organizations have called for better labelling on alcoholic drinks. However, there is a lack of consensus about the best elements to include. This review summarizes alcohol labelling policy worldwide and examines available evidence to support enhanced labelling. A literature review was carried out in June-July 2012 on Scopus using the key word 'alcohol' combined with 'allergens', 'labels', 'nutrition information', 'ingredients', 'consumer information' and/or 'warning'. Articles discussing advertising and promotion of alcohol were excluded. A search through Google and the System for Grey Literature in Europe (SIGLE) identified additional sources on alcohol labelling policies, mainly from governmental and organizational websites. Five elements were identified as potentially useful to consumers: (i) a list of ingredients, (ii) nutritional information, (iii) serving size and servings per container, (iv) a definition of 'moderate' intake and (v) a health warning. Alcohol labelling policy with regard to these aspects is quite rudimentary in most countries, with few requiring a list of ingredients or health warnings, and none requiring basic nutritional information. Only one country (Australia) requires serving size and servings per container to be displayed. Our study suggests that there are both potential advantages and disadvantages to providing consumers with more information about alcohol products. Current evidence seems to support prompt inclusion of a list of ingredients, nutritional information (usually only kcal) and health warnings on labels. Standard drink and serving size is useful only when combined with other health education efforts. A definition of 'moderate intake' and recommended drinking guidelines are best suited to other contexts.

In the United States, home care clinicians often start the episode of care devoid of relevant fall-risk information. By collecting and analyzing qualitative data from 30 clinicians in one home health agency, this case study aimed to understand how the currently adopted information technology solutions supported the clinicians' fall-risk management (FRM) information domains, and explored opportunities to adopt other solutions to better support FRM. The currently adopted electronic health record system and fall-reporting application served only some information domains with a limited capacity. Substantial improvement in addressing the FRM information domains is possible by effectively modifying the existing solutions and purposefully adopting new solutions.

NASA is currently engaged in the study phase of a modest effort to establish a Virtual Solar Observatory (VSO). The VSO would serve ground- and space-based solar physics data sets from a distributed network of archives through a small number of interfaces to the scientific community. The basis of this approach, as of all planned virtual observatories, is the translation of metadata from the various sources via source-specific dictionaries so the user will not have to distinguish among keyword usages. A single Web interface should give access to all the distributed data. We present the current status of the VSO, its initial scope, and its relation to the European EGSO effort.

Eliciting and utilizing rural students' funds of knowledge in the service of science learning: An action research study

NASA Astrophysics Data System (ADS)

Lloyd, Ellen M.

Several researchers have pointed out the failures of current schooling to adequately prepare students in science and called for radical reform in science education to address the problem. One dominant critique of science education is that several groups of students are not well served by current school science practices and discourses. Rural students represent one of these underserved populations. Yet, there is little in the literature that speaks specifically to reforming the science education of rural students. Utilizing action research as a methodology, this study was designed to learn more about the unique knowledge and life experiences of rural students, and how these unique knowledge, skills and interests could suggest new ways to improve science education in rural schools. Informed by this ultimate goal, I created an after school science club where the participating high school students engaged in solving a local watershed problem, while explicitly bringing to bear their unique backgrounds, local knowledge and life experiences from living in a rural area of Upstate New York. Using Funds of Knowledge as the theoretical framework, this after-school club served as the context to investigate the following research questions: (1) What science-related funds of knowledge do rural high school students have? (2) How were these funds of knowledge capitalized on to support science learning in an after-school setting?

Peer Education: Productive Engagement for Older African Americans in Recovery From Depression.

2017-06-17

Older adults who have personal experience with the mental health service delivery system gain unique and potentially valuable insight from their treatment experiences. Research suggests that incorporating trained individuals in recovery from a mental illness (i.e., peer educators) into mental health service delivery roles results in substantial benefits for current mental health consumers, particularly for older adults and racial and ethnic minorities who may feel disenfranchised from the traditional mental health service delivery system. However, little research has examined the impact of participating in these activities on the peer educators themselves. This mixed methods study examines the experiences of 10 African American older adults in recovery from depression currently working as trained peer educators. Peer educators reported feeling more positive, feeling their lives had significantly improved, and feeling better in general due to their peer educator roles. This qualitative investigation highlights four unique themes that can explain the benefit of serving in this capacity (i.e., Community Engagement, Life Long Learning and Education, Mental Health Recovery and Productive Aging). This study suggests that serving has a peer educator has a number of beneficial outcomes for African American older adults in recovery from depression. © The Author 2017.

The goal of the study was to estimate the prevalence of current and lifetime mental disorders in a consecutive sample (n=300) of detainees and prison inmates held in an Italian prison and compare it with the prevalence observed in a sample randomized from the community (n=300) within the same age interval (18-55 years) and sex proportion of prisoners, and with a similar socio-economic status. Psychiatric disorders were identified with the Mini International Neuropsychiatric Interview (MINI). Current psychiatric disorders were present in 58.7% of prisoners and 8.7% of the comparison group. Lifetime psychiatric disorders were present in 88.7% of prisoners and 15.7% of the comparison group. Current anxiety disorders and current stress-related disorders were related to prisoners serving their first-ever prison sentence. A variable fraction of prisoners with an ongoing psychopathology is not diagnosed or does not receive proper treatment. The provision of effective treatment to prisoners with psychiatric disorders might have potentially substantial public health benefits. Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.

Students with learning disabilities and hearing impairment: issues for the secondary and postsecondary teacher.

PubMed

Roth, V

1991-01-01

Although the number of students with both learning disability and hearing impairment (LDHI) currently enrolled in secondary and postsecondary programs has not been precisely determined, it is clear that these students are currently receiving inadequate assessment and support in many institutions. The best route for serving these students would seem to be collaborative efforts between deaf educators and learning disabilities specialists, yet serious gaps exist between these two professions in regard to interpretation of laws governing special services, training of professionals, and locations of educational programs. The difficulties of developing collaborative work have been compounded by controversies within each field and the heterogeneity of the populations served by both disciplines. Those interested in creating good LDHI assessments should begin by considering the qualifications needed by those conducting evaluation procedures. The inadequacies of current formal assessment devices for this population need to be recognized; informal procedures, such as teacher observation and curriculum-based assessments, are still some of the best tools available for identification and educational planning.

Electric Current Flow Through Two-Dimensional Networks

Gaspard, Mallory

In modern nanotechnology, two-dimensional atomic network structures boast promising applications as nanoscale circuit boards to serve as the building blocks of more sustainable and efficient, electronic devices. However, properties associated with the network connectivity can be beneficial or deleterious to the current flow. Taking a computational approach, we will study large uniform networks, as well as large random networks using Kirchhoff's Equations in conjunction with graph theoretical measures of network connectedness and flows, to understand how network connectivity affects overall ability for successful current flow throughout a network. By understanding how connectedness affects flow, we may develop new ways to design more efficient two-dimensional materials for the next generation of nanoscale electronic devices, and we will gain a deeper insight into the intricate balance between order and chaos in the universe.

Recently, khat chewing has become a common practice among high school, college, and university students. Regular khat chewing is thought to be a predisposing factor for different physical and mental health problems. It can lead to absenteeism from work and classes. In Ethiopia, to our knowledge no published study has investigated khat withdrawal symptoms. Therefore, this study was conducted to determine the prevalence, withdrawal symptoms, and associated factors of khat chewing among regular undergraduate students on the main campus of Jimma University in Ethiopia. The institution-based, cross-sectional study was conducted in January 2016. Data were collected from 651 main campus regular undergraduate students with a structured, self-administered questionnaire, entered into Epidata 3.1 and exported to SPSS version 20 for Windows. Bivariate and multivariate logistic regressions were used to explore associations and identify variables independently associated with khat chewing. The study found that the lifetime and current prevalence of khat chewing among students were 26.3% (95% CI: 24.3, 28.3) and 23.9% (95% CI: 21.94, 25.86), respectively. About 25.7% of students started chewing after joining university, and 60.5% of these students started during their first year. The main reason given for starting khat chewing was for study purposes (54.6%), followed by socialization purposes (42.3%). Among current khat chewers, 72.9% reported that they had chewed khat for 1 year or more and 68.2% reported that they had experienced various withdrawal symptoms. The most frequently reported withdrawal symptoms were feeling depressed, craving, and feeling fatigued. Being male, attending a place of worship daily/2-3 times per week, cannabis use, smoking cigarettes, and having family members currently chewing khat were independently associated with khat chewing. This study found that large numbers of university students were currently chewing khat. In this study withdrawal symptoms and factors that significantly affect khat chewing were identified. Besides it gave new ideas regarding khat withdrawal symptoms in Ethiopia. It serves as a critical role of providing information to form rational foundation for public health policy, prevention and planning to bring change in contributing factors for Khat chewing. The finding will be serving as base line information for further study.

To conduct a systematic assessment of library and informatics training at accredited Western U.S. medical schools. To provide a structured description of core practices, detect trends through comparisons across institutions, and to identify innovative training approaches at the medical schools. Action research study pursued through three phases. The first phase used inductive analysis on reported library and informatics skills training via publicly-facing websites at accredited medical schools and the academic health sciences libraries serving those medical schools. Phase Two consisted of a survey of the librarians who provide this training to undergraduate medical education students at the Western U.S. medical schools. The survey revealed gaps in forming a complete picture of current practices, thereby generating additional questions that were answered through the Phase Three in-depth interviews. Publicly-facing websites reviewed in Phase One offered uneven information about library and informatics training at Western U.S. medical schools. The Phase Two survey resulted in a 77% response rate. The survey produced a clearer picture of current practices of library and informatics training. The survey also determined the readiness of medical students to pass certain aspects of the United States Medical Licensure Exam. Most librarians interacted with medical school curricular leaders through either curricula committees or through individual contacts. Librarians averaged three (3) interventions for training within the four-year curricula with greatest emphasis upon the first and third years. Library/informatics training was integrated fully into the respective curricula in almost all cases. Most training involved active learning approaches, specifically within Problem-Based Learning or Evidence-Based Medicine contexts. The Phase Three interviews revealed that librarians are engaged with the medical schools' curricular leaders, they are respected for their knowledge and teaching skills, and that they need to continually adapt to changes in curricula. This study offers a long overdue, systematic view of current practices of library/informatics training at Western U.S. medical schools. Medical educators, particularly curricular leaders, will find opportunities in this study's results for more productive collaborations with the librarians responsible for library and informatics training at their medical schools.

The APDRC mission is to increase understanding of climate variability in the Asia-Pacific region by developing the computational, data-management, and networking infrastructure necessary to make data resources readily accessible and usable by researchers, and by undertaking data-intensive research activities that will both advance knowledge and lead to improvements in data preparation and data products. A focus of recent activity is the implementation of user-friendly data servers. The APDRC is currently running a Live Access Server (LAS) developed at NOAA/PMEL to provide access to and visualization of gridded climate products via the web. The LAS also allows users to download the selected data subsets in various formats (such as binary, netCDF and ASCII). Most of the datasets served by the LAS are also served through our OPeNDAP server (formerly DODS), which allows users to directly access the data using their desktop client tools (e.g. GrADS, Matlab and Ferret). In addition, the APDRC is running an OPeNDAP Catalog/Aggregation Server (CAS) developed by Unidata at UCAR to serve climate data and products such as model output and satellite-derived products. These products are often large (> 2 GB) and are therefore stored as multiple files (stored separately in time or in parameters). The CAS remedies the inconvenience of multiple files and allows access to the whole dataset (or any subset that cuts across the multiple files) via a single request command from any DODS enabled client software. Once the aggregation of files is configured at the server (CAS), the process of aggregation is transparent to the user. The user only needs to know a single URL for the entire dataset, which is, in fact, stored as multiple files. CAS even allows aggregation of files on different systems and at different locations. Currently, the APDRC is serving NCEP, ECMWF, SODA, WOCE-Satellite, TMI, GPI and GSSTF products through the CAS. The APDRC is also running an EPIC server developed by PMEL/NOAA. EPIC is a web-based, data search and display system suited for in situ (station versus gridded) data. The process of locating and selecting individual station data from large collections (millions of profiles or time series, etc.) of in situ data is a major challenge. Serving in situ data on the Internet faces two problems: the irregularity of data formats; and the large quantity of data files. To solve the first problem, we have converted the in situ data into netCDF data format. The second problem was solved by using the EPIC server, which allows users to easily subset the files using a friendly graphical interface. Furthermore, we enhanced the capability of EPIC and configured OPeNDAP into EPIC to serve the numerous in situ data files and to export them to users through two different options: 1) an OPeNDAP pointer file of user-selected data files; and 2) a data package that includes meta-information (e.g., location, time, cruise no, etc.), a local pointer file, and the data files that the user selected. Option 1) is for those who do not want to download the selected data but want to use their own application software (such as GrADS, Matlab and Ferret) for access and analysis; option 2) is for users who want to store the data on their own system (e.g. laptops before going for a cruise) for subsequent analysis. Currently, WOCE CTD and bottle data, the WOCE current meter data, and some Argo float data are being served on the EPIC server.

Deviance as adherence to injunctive group norms: the overlooked role of social identification in deviance.

PubMed

Crane, Monique F; Platow, Michael J

2010-12-01

We currently report three studies investigating group members' expressions of dissatisfaction and discontent with the behaviour and attitudes of their in-group members. Our analysis examines the context in which group members will deviate from actual group member behaviour. We argue that highly identifying group members will challenge fellow group member behaviour when that group member behaviour is perceived to violate injunctive group norms. Further, we predicted that high identifiers would still challenge such group member behaviour even if that behaviour were conducted by a majority of group members. Thus, high identifiers were predicted to express descriptively deviant opinions when the behaviour of other members contravenes injunctive group norms. In Studies 1 and 2, group-level self-definition served as a moderator in the relationship between the expression of discontent and perceived injunctive norm violation; in Study 3, group-level self-investment served as this moderator. The findings supported our predictions. This support was particularly strong when a majority of group members violated group norms. Implications for the analysis of the relationship between social identification and deviance are discussed.

Agriculture interventions such as irrigation, improved fertilization, and advanced cultivars have the potential to increase food security and ensure climate resilience. However, in order broaden the support of activities like these, environmental managers must be able to assess their impact. Often field data are difficult to obtain and decisions are made with limited information. Satellite products can provide relevant information at field and village wide scales that can assist in this process. SERVIR is taking an aim of helping connect the space-based products to help the efficacy of village scale interventions through a couple of web-based tools, called ClimateSERV and AgriSERV. ClimateSERV has been active since 2014, and has increased in the data holdings and access points. Currently, ClimateSERV enables users to create geographic regions of their choosing and to compute key statistics for those regions. Rainfall (GPM IMERG, CHIRPS), vegetation indices (eMODIS Normalized Difference Vegetation Index - NDVI; Evaporative Stress Index), and North American Multi-model Ensemble-based seasonal climate forecasts of rainfall and temperature. ClimateSERV can also query the Google Earth Engine holdings for datasets, currently, ClimateSERV provides access to the daytime MODIS Land Surface Temperature (LST). Our first such derived product is a monthly rainfall analysis feature which combines CHIRPS historic rainfall with seasonal forecast models AgriSERV is a derived web-based tool based on the ClimateSERV data holdings. It is designed to provide easy to interpret analysis, based NDVI and rainfall. This tool allows users to draw two areas of interest, one control with no intervention and another that has experienced intervention. An on-demand comparative analysis is performed and the user is presented with side-by-side charts and summary data that highlight the differences of the two areas in terms of vegetation health, derived growing season lengths and rainfall. The analysis is based on an area-weighted average of the gridded NDVI and rainfall data. The users can download the summary data table as well as the full dataset for the period specified. This presentation is intended to showcase the utility of the intervention programs and to provide an objective rationale for expansion of those intervention programs.

Identifying drivers of biodiversity change from fossil long-lived lakes: lessons for risk and resilience of todays long-lived lake biota.

NASA Astrophysics Data System (ADS)

Wesselingh, Frank

2015-04-01

Several fossil long-lived lake systems exist that have a very good spatiotemporal geological and faunal record enabling us to study timeseries of biodiversity change. These complexes, such as the Miocene Pannonian and Quaternary Pontocaspian systems of Europe, Quaternary Lake Biwa in Japan and the Miocene Pebas System in South America enable us to assess the impact of environmental stability and pertubation on component processes of turnover, e.g. migration, speciation and extinction/ extirpation. Also, the temporal dimensions of such processes can be clarified and compared to the nature and rates of current turnover in long-lived lake systems. Our studies suggest that we are currently witnessing dramatic biodiversity loss caused mostly by habitat degradation and destruction in smaller lakes and invasives in larger lakes that may exceed the potential of endemic lake biota to recover. Long-live lakes should serve as an excellent illustration of the magnitude of the current anthropogenic-induced biodiversity crisis.

As we fall asleep we forget about the future: A quantitative linguistic analysis of mentation reports from hypnagogia.

We present a quantitative study of mental time travel to the past and future in sleep onset hypnagogia. Three independent, blind judges analysed a total of 150 mentation reports from different intervals prior to and after sleep onset. The linguistic tool for the mentation report analysis grounds on established grammatical and cognitive-semantic theories, and proof of concept has been provided in previous studies. The current results indicate that memory for the future, but not for the past, decreases in sleep onset - thereby supporting preliminary physiological evidence at the level of brain function. While recent memory research emphasizes similarities in the cognitive and physiological processes of mental time travel to the past and future, the current study explores a state of consciousness which may serve to dissociate between the two.

The aim of the study was to assess the likely impact of the Scottish Government's proposed alcohol minimum unit pricing (MUP) policy on community off-sales outlets (convenience stores or corner shops), and, in turn, on the local people who purchase drinks at such premises. This research adds to our knowledge by linking sales of alcohol products which will be affected by MUP (e.g. at the proposed 50 ppu) to the types of communities where these are the 'drinks-of-choice'. A survey of independent community off-sales operating within the city of Glasgow, Scotland (n = 271) returned 144 completed questionnaires enquiring about each shop's customer base, best-selling alcohol products and participating shopkeepers' views on MUP. Responses were measured against current alcohol product prices (i.e. whether potentially affected by MUP) and local levels of socio-economic deprivation. Participating shopkeepers were divided in their support for MUP, although more were in favour than against. Support for MUP tended to be rooted in business concerns. A majority reported having at least one best-selling alcohol product which will be affected by the proposed MUP policy at current prices, with the beverages that would be most affected (e.g. white cider) tending to be best-sellers at shops serving deprived communities. MUP is likely to impact most in socio-economically deprived communities. This is also where alcohol-related health and other inequalities are currently greatest.

Energy bandwidth studies of U.S. manufacturing sectors can serve as foundational references in framing the range (or bandwidth) of potential energy savings opportunities. This bandwidth study examines energy consumption and potential energy savings opportunities in U.S. chemical manufacturing. The study relies on multiple sources to estimate the energy used in the production of 74 individual chemicals, representing 57% of sector-wide energy consumption. Energy savings opportunities for individual chemicals and for 15 subsectors of chemicals manufacturing are based on technologies currently in use or under development; these potential savings are then extrapolated to estimate sector-wide energy savings opportunity.

Background In the 1990s, congenital anomalies were reported among children whose fathers had served aboard a Norwegian missile torpedo boat (MTB). The Royal Norwegian Navy asked the University of Bergen to look into this problem as one part of a general health and work environment surveillance. Aims To estimate any increased risk of having children with congenital anomalies and having stillborn children among the offspring of workers that had served aboard the MTB and to investigate possible differences in exposure and other risk factors between these groups. Methods Data from a cross‐sectional study among all current employees of the Norwegian Navy (n = 2265, response rate 58%) were analysed. Results The prevalence ratio of having a child with congenital malformations associated with working on the ship was 4.0 (95% CI 1.9 to 8.6). The prevalence ratio of having a child who was stillborn or died within one week was 4.1 (95% CI 1.7 to 9.9). Conclusion Service aboard the MTB was associated with an increased risk of having children with congenital birth defects and having children that were stillborn. The causes of these findings are unknown. PMID:16421386

We assessed the feasibility of developing a suitable international reference standard for determination of in vitro biological activity of human sequence recombinant PEG-G-CSF products with a 20 kD linear PEG linked to the N-terminal methionyl residue of G-CSF (INN Filgrastim), produced using a conjugation process and coupling chemistry similar to that employed for the lead PEGfilgrastim product. Based on initial data which showed that the current WHO 2nd international standard, IS for G-CSF (09/136) or alternatively, a PEG-G-CSF standard with a unitage traceable to the G-CSF IS may potentially serve as the IS for PEG-G-CSF products, two candidate preparations of PEG-G-CSF were formulated and lyophilized at NIBSC. These preparations were tested by 23 laboratories using in vitro bioassays in a multi-centre collaborative study. Results indicated that on the basis of parallelism, the current WHO 2nd IS for G-CSF or any of the PEG-G-CSF samples could be used as the international standard for PEG-G-CSF preparations. However, because of the variability in potency estimates seen when PEG-G-CSF preparations were compared with the current WHO 2nd IS for G-CSF, a candidate PEG-G-CSF was suitable as the WHO IS. The preparation 12/188 was judged suitable to serve as the WHO IS based on in vitro biological activity data. Therefore, the preparation coded 12/188 was established by the WHO Expert Committee on Biological Standardization (ECBS) in 2013 as the WHO 1st IS for human PEGylated G-CSF with an assigned in vitro bioactivity of 10,000 IU per ampoule.

There is a long-standing belief that 'you can make anything out of lignin...except money.' This chapter serves to highlight that opportunities for making money from biomass-derived lignin exist both with current technology in the production of steam and power to new emerging areas of R&D focused on value-added chemical and material coproducts from lignin. To understand and quantify the economic potential for lignin valorization, the techno-economic analysis methodology is first described in detail. As demonstrated in the provided case study, these types of economic evaluations serve not only to estimate the economic impacts that lignin conversion could have for anmore » integrated biorefinery and outline drivers for further cost reduction but also identify data gaps and R&D needs for improving the design basis and reducing the risk for process scale-up.« less

Teaching Electric Fences: The Physics Behind the Brainiac Video

NASA Astrophysics Data System (ADS)

Vollmer, Michael

2016-11-01

In many states, electric fences are used to prevent animals from leaving a designated area, for example for grazing. They are quite well known by most students and can therefore serve as daily-life examples of electric circuits. Besides helping to grasp the ideas of Kirchhoff's laws for voltages and currents in circuits according to loop and junction rules, they can also serve as introduction to the topic of conduction of electricity by humans and respective effects (in contrast to electric fences, the latter can also be studied experimentally in the classroom). Here we provide background information on the circuit diagrams of electrical fences that also explains the so-called Brainiac YouTube videos on the topic. While electric fences are designed not to be dangerous to humans or animals due to the short duration of the electrical pulses, students and teachers are strongly discouraged from attempting to replicate the scenes enacted in the video.

Light Trapping with Silicon Light Funnel Arrays

PubMed Central

Nissan, Yuval; Gabay, Tamir; Shalev, Gil

2018-01-01

Silicon light funnels are three-dimensional subwavelength structures in the shape of inverted cones with respect to the incoming illumination. Light funnel (LF) arrays can serve as efficient absorbing layers on account of their light trapping capabilities, which are associated with the presence of high-density complex Mie modes. Specifically, light funnel arrays exhibit broadband absorption enhancement of the solar spectrum. In the current study, we numerically explore the optical coupling between surface light funnel arrays and the underlying substrates. We show that the absorption in the LF array-substrate complex is higher than the absorption in LF arrays of the same height (~10% increase). This, we suggest, implies that a LF array serves as an efficient surface element that imparts additional momentum components to the impinging illumination, and hence optically excites the substrate by near-field light concentration, excitation of traveling guided modes in the substrate, and mode hybridization.

Research shows a positive relationship between dietary energy density (ED) and body mass index (BMI), but dietary ED of weight loss maintainers is unknown. This preliminary investigation was a secondary data analysis that compared self-reported dietary ED and food group servings consumed in overweight adults (OW: BMI=27-45kg/m(2)), normal weight adults (NW: BMI=19-24.9 kg/m(2)), and weight loss maintainers (WLM: current BMI=19-24.9kg/m(2) [lost≥10% of maximum body weight and maintained loss for ≥5years]) participating in 2 studies, with data collected from July 2006 to March 2007. Three 24-h phone dietary recalls from 287 participants (OW=97, NW=85, WLM=105) assessed self-reported dietary intake. ED (kcal/g) was calculated by three methods (food+all beverages except water [F+AB], food+caloric beverages [F+CB], and food only [FO]). Differences in self-reported consumption of dietary ED, food group servings, energy, grams of food/beverages, fat, and fiber were assessed using one-way MANCOVA, adjusting for age, sex, and weekly energy expenditure from self-reported physical activity. ED, calculated by all three methods, was significantly lower in WLM than in NW or OW (FO: WLM=1.39±0.45kcal/g; NW=1.60±0.43 kcal/g; OW=1.83±0.42 kcal/g). Self-reported daily servings of vegetables and whole grains consumed were significantly higher in WLM compared to NW and OW (vegetables: WLM=4.9±3.1 servings/day; NW=3.9±2.0 servings/day; OW=3.4±1.7 servings/day; whole grains: WLM=2.2±1.8 servings/day; NW=1.4±1.2 servings/day; OW=1.3±1.3 servings/day). WLM self-reported consuming significantly less energy from fat and more fiber than the other two groups. Self-reported energy intake per day was significantly lower in WLM than OW, and WLM self-reported consuming significantly more grams of food/beverages per day than OW. These preliminary findings suggest that consuming a diet lower in ED, characterized by greater intake of vegetables and whole grains, may aid with weight loss maintenance and should be further tested in prospective randomized controlled trials.

The Food Frequency Questionnaire (FFQ) is one of the most commonly used tools in epidemiologic studies to assess long-term nutritional exposure. The purpose of this study is to describe the development of a culture specific FFQ for Arab populations in the United Arab Emirates (UAE) and Kuwait. We interviewed samples of Arab populations over 18 years old in UAE and Kuwait assessing their dietary intakes using 24-hour dietary recall. Based on the most commonly reported foods and portion sizes, we constructed a food list with the units of measurement. The food list was converted to a Semi-Quantitative Food Frequency Questionnaire (SFFQ) format following the basic pattern of SFFQ using usual reported portions. The long SFFQ was field-tested, shortened and developed into the final SFFQ. To estimate nutrients from mixed dishes we collected recipes of those mixed dishes that were commonly eaten, and estimated their nutritional content by using nutrient values of the ingredients that took into account method of preparation from the US Department of Agriculture's Food Composition Database. The SFFQs consist of 153 and 152 items for UAE and Kuwait, respectively. The participants reported average intakes over the past year. On average the participants reported eating 3.4 servings/d of fruits and 3.1 servings/d of vegetables in UAE versus 2.8 servings/d of fruits and 3.2 servings/d of vegetables in Kuwait. Participants reported eating cereals 4.8 times/d in UAE and 5.3 times/d in Kuwait. The mean intake of dairy products was 2.2/d in UAE and 3.4 among Kuwaiti. We have developed SFFQs to measure diet in UAE and Kuwait that will serve the needs of public health researchers and clinicians and are currently validating those instruments.

Mesh-matrix analysis method for electromagnetic launchers

Elliott, David G.

1989-01-01

The mesh-matrix method is a procedure for calculating the current distribution in the conductors of electromagnetic launchers with coil or flat-plate geometry. Once the current distribution is known the launcher performance can be calculated. The method divides the conductors into parallel current paths, or meshes, and finds the current in each mesh by matrix inversion. The author presents procedures for writing equations for the current and voltage relations for a few meshes to serve as a pattern for writing the computer code. An available subroutine package provides routines for field and flux coefficients and equation solution.

The Impact of Affect on Out-Group Judgments Depends on Dominant Information-Processing Styles: Evidence From Incidental and Integral Affect Paradigms.

PubMed

Isbell, Linda M; Lair, Elicia C; Rovenpor, Daniel R

2016-04-01

Two studies tested the affect-as-cognitive-feedback model, in which positive and negative affective states are not uniquely associated with particular processing styles, but rather serve as feedback about currently accessible processing styles. The studies extend existing work by investigating (a) both incidental and integral affect, (b) out-group judgments, and (c) downstream consequences. We manipulated processing styles and either incidental (Study 1) or integral (Study 2) affect and measured perceptions of out-group homogeneity. Positive (relative to negative) affect increased out-group homogeneity judgments when global processing was primed, but under local priming, the effect reversed (Studies 1 and 2). A similar interactive effect emerged on attributions, which had downstream consequences for behavioral intentions (Study 2). These results demonstrate that both incidental and integral affect do not directly produce specific processing styles, but rather influence thinking by providing feedback about currently accessible processing styles. © 2016 by the Society for Personality and Social Psychology, Inc.

Multifaceted role of lipids in Mycobacterium leprae.

PubMed

Kaur, Gurkamaljit; Kaur, Jagdeep

2017-03-01

Mycobacterium leprae must adopt a metabolic strategy and undergo various metabolic alterations upon infection to survive inside the human body for years in a dormant state. A change in lipid homeostasis upon infection is highly pronounced in Mycobacterium leprae. Lipids play an essential role in the survival and pathogenesis of mycobacteria. Lipids are present in several forms and serve multiple roles from being a source of nutrition, providing rigidity, evading the host immune response to serving as virulence factors, etc. The synthesis and degradation of lipids is a highly regulated process and is the key to future drug designing and diagnosis for mycobacteria. In the current review, an account of the distinct roles served by lipids, the mechanism of their synthesis and degradation has been elucidated.

Feminist theorizing as 'transposed autobiography'.

PubMed

Hoogland, Renée C

2007-01-01

This piece considers personal investments endemic in academic writing, more specifically, in Lesbian Studies. Taking Elizabeth Bowen's phrase, "transposed autobiography," as a starting-point, the author briefly discusses the development of lesbian/straight feminist debates, and continues to explore the relative absence of lesbianism in current feminist and queer theorizing. Three 'moments' serve to explain the casting aside of lesbian desire: the subsidence of lesbian/straight feminist debates, the prevalence of 'race'/ethnicity in critical theorizing and the emergence of post-theoretical trends of thought.

A longitudinal analysis (1984-2005) of media language in Norway is presented, demonstrating how the current globalized capitalist market ideology is now permeating this long-established Scandinavian welfare state. This ideological shift carries powerful implications for community psychology, as traditional welfare state values of equal services based on a universalistic principle are set aside, and social and material inequalities are increasingly accepted. The methodology developed in the present study may serve as a "barometer of community changes", to borrow a metaphor used by Sarason (2000).

This review article is a current survey of excipients used in approved injectable products. Information provided includes concentration ranges, function, frequency of use, and role in dosage form. This article is an update of a paper published more than a decade ago (reference 11). Since then many new products have been approved. Safety concerning excipients has evolved as the scientific community continues to learn about their usage. New excipients are being used in early phases of clinical trials to support novel therapeutic entities like RNAi, aptamers, anti-sense, fusion proteins, monoclonal antibodies, and variant scaffolds. Because these excipients are not inert, various pharmacopoeias are responding with monographs or informational chapters addressing excipient functionality. The final sections of this article discuss new excipients, serving specific needs that traditional excipients are unable to provide and for which safety studies are necessary to support a novel excipient for marketing applications. Excipients are added to parenteral dosage forms to serve a variety of functions including stabilization and as vehicles.

Reporting Military Sexual Trauma: A Mixed-Methods Study of Women Veterans' Experiences Who Served From World War II to the War in Afghanistan.

PubMed

Wolff, Kristina B; Mills, Peter D

2016-08-01

Since 2004, there has been increased effort to reduce military sexual trauma (MST) in the U.S. military. Although MST covers a range of inappropriate behaviors, the majority of research, treatment, and outreach are focused on sexual assault and the experiences of individuals serving in Afghanistan and Iraq. During a study on veterans' involvement in a national peace organization, participants were asked about their military experiences. Veterans served from World War II to current conflicts in Iraq and Afghanistan. Emerging out of the responses were descriptions of women's experiences with MST, barriers to reporting incidents of sexual misconduct and sexual assault, and the challenges they faced when seeking care. Data were gathered using anonymous questionnaires and semi-structured interviews. Out of 52 female veterans, the majority (90%) was subjected to at least one form of MST, and 15% (8) attempted to report the incident(s). Over half of the assailants were of a higher rank than the survivors. The majority of veterans remained silent due to lack of options to report, the status of perpetrators, and fear of retaliation. These data provide a glimpse into the challenges many women veterans faced when seeking assistance reporting incidents or obtaining health care for their MST.

Modulation of Molecular Flux Using a Graphene Nanopore Capacitor.

PubMed

Shankla, Manish; Aksimentiev, Aleksei

2017-04-20

Modulation of ionic current flowing through nanoscale pores is one of the fundamental biological processes. Inspired by nature, nanopores in synthetic solid-state membranes are being developed to enable rapid analysis of biological macromolecules and to serve as elements of nanofludic circuits. Here, we theoretically investigate ion and water transport through a graphene-insulator-graphene membrane containing a single, electrolyte-filled nanopore. By means of all-atom molecular dynamics simulations, we show that the charge state of such a graphene nanopore capacitor can regulate both the selectivity and the magnitude of the nanopore ionic current. At a fixed transmembrane bias, the ionic current can be switched from being carried by an equal mixture of cations and anions to being carried almost exclusively by either cationic or anionic species, depending on the sign of the charge assigned to both plates of the capacitor. Assigning the plates of the capacitor opposite sign charges can either increase the nanopore current or reduce it substantially, depending on the polarity of the bias driving the transmembrane current. Facilitated by the changes of the nanopore surface charge, such ionic current modulations are found to occur despite the physical dimensions of the nanopore being an order of magnitude larger than the screening length of the electrolyte. The ionic current rectification is accompanied by a pronounced electro-osmotic effect that can transport neutral molecules such as proteins and drugs across the solid-state membrane and thereby serve as an interface between electronic and chemical signals.

American Military Veteran Entrepreneurs: A Comprehensive Profile of Demographic, Service History, and Psychosocial Characteristics

2017-01-01

American military veterans are nearly twice as likely to be self-employed compared to non-veterans, and are majority owners in nine percent of all businesses nationwide. Despite their contribution to the broader economy and the potential for training programs to cultivate and foster successful self-employment and veteran-lead entrepreneurial ventures, research on veteran entrepreneurs remains limited. In order to gain a better understanding of the potential strengths and vulnerabilities of veteran entrepreneurs, the current study utilized data from a large, nationally representative sample to profile self-employed veterans (n=230) and compare them to veterans who work as employees (n=1,055) with respect to demographic, military service history, and psychosocial characteristics. Results indicated that self-employed veterans were older and more educated and more likely to utilize VA healthcare. Self-employed veterans were more likely to serve in Vietnam and to serve in the military for fewer years. No differences were noted in perceived military experience, level of combat exposure, or military branch served as a function of self-employment. Although reporting more lifetime traumas, self-employed veterans did not experience higher rates of current or lifetime psychopathology or lower perceived quality of life. Potential protective resilience-promoting factors may be associated with the higher levels of openness, extraversion, optimism, achievement-orientation (purpose in life), and greater need for autonomy and professional development observed among self-employed veterans. Moreover, self-employed veterans demonstrated higher levels of gratitude, community integration, and altruistic service to others. Findings have potential to inform human resources management strategies and vocational training and reintegration initiatives for veterans. PMID:29290645

Self-assembly of organic monolayers as protective and conductive bridges for nanometric surface-mount applications.

PubMed

Platzman, Ilia; Haick, Hossam; Tannenbaum, Rina

2010-09-01

In this work, we present a novel surface-mount placement process that could potentially overcome the inadequacies of the currently used stencil-printing technology, when applied to devices in which either their lateral and/or their horizontal dimensions approach the nanometric scale. Our novel process is based on the "bottom-up" design of an adhesive layer, operative in the molecular/nanoscale level, through the use of self-assembled monolayers (SAMs) that could form protective and conductive bridges between pads and components. On the basis of previous results, 1,4-phenylene diisocyanide (PDI) and terephthalic acid (TPA) were chosen to serve as the best candidates for the achievement of this goal. The quality and stability of these SAMs on annealed Cu surfaces (Rrms=0.15-1.1 nm) were examined in detail. Measurements showed that the SAMs of TPA and PDI molecules formed on top of Cu substrates created thermally stable organic monolayers with high surface coverage (∼90%), in which the molecules were closely packed and well-ordered. Moreover, the molecules assumed a standing-up phase conformation, in which the molecules bonded to the Cu substrate through one terminal functional group, with the other terminal group residing away from the substrate. To examine the ability of these monolayers to serve as "molecular wires," i.e., the capability to provide electrical conductivity, we developed a novel fabrication method of a parallel plate junction (PPJ) in order to create symmetric Cu-SAM-Cu electrical junctions. The current-bias measurements of these junctions indicated high tunneling efficiency. These achievements imply that the SAMs used in this study can serve as conductive molecular bridges that can potentially bind circuital pads/components.

2009-01-01

Objective This study examined the association of lifetime traumatic stress with psychiatric diagnostic status and symptom severity in veterans serving in the US military after 9/11/01. Method Data from 356 US military veterans were analyzed. Measures included a standardized clinical interview measure of psychiatric disorders, and paper-and-pencil assessments of trauma history, demo-graphic variables, intellectual functioning, posttraumatic stress disorder (PTSD) symptoms, depression, alcohol misuse, and global distress. Results Ninety-four percent of respondents reported at least one traumatic stressor meeting DSM-IV criterion A for PTSD (i.e., life threatening event to which the person responded with fear, helplessness or horror), with a mean of four criterion A traumas. Seventy-one percent reported serving in a war-zone, with 50% reporting occurrence of an event meeting criterion A. The rate of current psychiatric disorder in this sample was: 30% PTSD, 20% major depressive disorder, 6% substance abuse or dependence and 10% for the presence of other Axis I psychiatric disorders. After accounting for demographic covariates and combat exposure, childhood physical assault and accident/disasters were most consistently associated with increased likelihood of PTSD. However, PTSD with no comorbid major depressive disorder or substance use disorder was predicted only by combat exposure and adult physical assault. Medical/unexpected-death trauma and adult physical assault were most consistently associated with more severe symptomatology. Conclusions Particular categories of trauma were differentially associated with the risk of psychiatric diagnosis and current symptom severity. These findings underscore the importance of conducting thorough assessment of multiple trauma exposures when evaluating recently post-deployed veterans. PMID:19232639

2011-01-01

Summary Background and objectives Sugar-sweetened soda is reported to be associated with increased risk for diabetes and albuminuria, but there are currently limited data on how sugar or artificially sweetened soda may be related to kidney function decline. Design, setting, participants, & measurements This study identified 3318 women participating in the Nurses' Health Study with data on soda intake and albuminuria; of these, 3256 also had data on estimated GFR (eGFR) change between 1989 and 2000. Cumulative average beverage intake was derived from the 1984, 1986, 1990, 1994, and 1998 food frequency questionnaires. Serving categories included <1/mo (referent), 1 to 4/mo, 2 to 6/wk, 1 to 1.9/d, and ≥2/d. Microalbuminuria (MA) was considered a urinary albumin-to-creatinine ratio of 25 to 355 μg/mg. For kidney function change, the primary outcome was a ≥30% decline in eGFR over 11 years; rapid eGFR decline defined as ≥3 ml/min per 1.73 m2 per year was also examined. Results Consumption of ≥2 servings per day of artificially sweetened (diet) soda was independently associated with eGFR decline ≥30% (OR 2.02, 95% CI 1.36 to 3.01) and ≥3 ml/min per 1.73 m2 per year (OR 2.20, 95% CI 1.36 to 3.55). No increased risk for eGFR decline was observed for <2 servings per day of diet soda. No associations were noted between diet soda and MA or sugar soda and MA or eGFR decline. Conclusions Consumption of ≥2 servings per day of artificially sweetened soda is associated with a 2-fold increased odds for kidney function decline in women. PMID:20884773

Consumption of sugar-sweetened beverages (SSBs) is associated with cardiovascular disease risk factors. This study examined the relationships between SSB consumption and demographic, health behavior, health service, and health condition characteristics of adult patients of a network of federally qualified health centers (FQHCs) in a low-income, urban setting. Validated, standardized self-reported health behavior questions were incorporated into the electronic health record (EHR) and asked of patients yearly, at 4 FQHCs. We conducted cross-sectional analysis of EHR data collected in 2013 from 12,214 adult patients by using logistic regression. Forty percent of adult patients consumed 1 or more SSBs daily. The adjusted odds ratios indicated that patients who consumed more than 1 SSB daily were more likely to be aged 18 to 29 years versus age 70 or older, current smokers versus never smoking, eating no servings of fruits and/or vegetables daily or 1 to 4 servings daily versus 5 or more servings daily, and not walking or biking more than 10 blocks in the past 30 days. Patients consuming 1 or more servings of SSBs daily were less likely to speak Spanish than English, be women than men, be diagnosed with type 2 diabetes versus no diabetes, and be diagnosed with hypertension versus no hypertension. SSB consumption differed by certain demographic characteristics, health behaviors, and health conditions. Recording SSB intake and other health behaviors data in the EHR could help clinicians in identifying and counseling patients to promote health behavior changes. Future studies should investigate how EHR data on patient health behavior can be used to improve the health of patients and communities.

The role of civil society in health care reforms: an arena for hegemonic struggles.

Filc, Dani

2014-12-01

The present paper argues that current mainstream understandings of civil society as ontologically different from the state and essentially positive (either normative or functionally) are problematic in order to understand the development of health care reforms. The paper proposes to ground an explanation of the role of civil society in health care reforms in a Gramscian understanding of civil society as analytically different from the state, and as an arena for hegemonic struggles. The study of health care reform in Israel serves as a case study for this claim. Copyright © 2014 Elsevier Ltd. All rights reserved.

Electron transport in Bi2Se3 ultra thin films

Bauer, Sebastian; Bernhart, Alexander M.; Bobisch, Christian A.

2018-02-01

We studied the electronic transport properties of a 4 QL thin Bi2Se3 film in the hybridized phase on Si(111) by scanning tunneling potentiometry. When a transverse voltage is applied, the film exhibits a homogeneous electric field on the nm scale. In addition, thermovoltage signals with lateral nm variations are found which result from sample heating by the transverse current. The thermovoltage signals are directly correlated to morphological structures on the surface, i.e. step edges, and indicate a lateral variation of the local density of states at the Bi2Se3 surface. No discernible voltage drops appear at the surface so that the whole film serves as a current carrying medium and scattering at surface defects is less important.

Long-read sequencing of chicken transcripts and identification of new transcript isoforms.

The chicken has long served as an important model organism in many fields, and continues to aid our understanding of animal development. Functional genomics studies aimed at probing the mechanisms that regulate development require high-quality genomes and transcript annotations. The quality of these resources has improved dramatically over the last several years, but many isoforms and genes have yet to be identified. We hope to contribute to the process of improving these resources with the data presented here: a set of long cDNA sequencing reads, and a curated set of new genes and transcript isoforms not currently represented in the most up-to-date genome annotation currently available to the community of researchers who rely on the chicken genome.

Correlation of open cell-attached and excised patch clamp techniques.

PubMed

Filipovic, D; Hayslett, J P

1995-11-01

The excised patch clamp configuration provides a unique technique for some types of single channel analyses, but maintenance of stable, long-lasting preparations may be confounded by rundown and/or rapid loss of seal. Studies were performed on the amiloride-sensitive Na+ channel, located on the apical surface of A6 cells, to determine whether the nystatin-induced open cell-attached patch could serve as an alternative configuration. Compared to excised inside-out patches, stable preparations were achieved more readily with the open cell-attached patch (9% vs. 56% of attempts). In both preparations, the current voltage (I-V) relation was linear, current amplitudes were equal at opposite equivalent clamped voltages, and Erev was zero in symmetrical Na+ solutions, indicating similar Na+ activities on the cytosolic and external surfaces of the patch. Moreover, there was no evidence that nystatin altered channel activity in the patch because slope conductance (3-4pS) and Erev (75 mV), when the bath was perfused with a high K:low Na solution (ENa = 80 mV), were nearly equal in both patch configurations. Our results therefore indicate that the nystatin-induced open cell-attached patch can serve as an alternative approach to the excised inside-out patch when experiments require modulation of univalent ions in the cytosol.

In their own words: A qualitative study exploring influences on the food choices of university students.

2018-06-11

University students generally make independent decisions regarding food choices. Current research about knowledge of Australian Dietary Guidelines (ADG), sources of nutrition information and influences on food choices for this group is scarce. Qualitative data was collected from gender separated focus groups comprising four female (n=31) and four male (n=18) to identify: knowledge of ADG, sources of nutrition information; factors that influence food choices; perceived relevant nutrition messages and how best to deliver them. Gaps in knowledge were identified particularly regarding number of serves and serving size for food groups. Social media was the most commonly reported source of knowledge. Social media was also a major influence on food choice due to its impact on body ideals. Current health promotion nutrition messages were perceived irrelevant given the focus on long-term health risks. Health and adhering to the ADG were not identified as important. The desire to look a particular way was the major influence on food choices. SO WHAT?: While there is an awareness of ADG, our participants made a deliberate decision not to follow them. This provides a challenge for developing relevant preventive health messages for this target audience. This article is protected by copyright. All rights reserved.

The aim of this study was to compare the effect of supine versus lateral position on clinical signs of fat embolism during orthopedic trauma surgery. Dogs served as the current study model, which could be extended and/or serve as a basis for future in vivo studies on humans. It was hypothesized that there would be an effect of position on clinical signs of fat embolism syndrome in a dog model. 12 dogs were assigned to supine (n = 6) and lateral (n = 6) position groups. Airway pressures, heart rate, blood pressure, cardiac output, pulmonary artery pressure, pulmonary artery wedge pressure, right atrial pressure, arterial and venous blood gases, white blood count, platelet count and neutrophil count were obtained. Dogs were then subjected to pulmonary contusion in three areas of one lung. Fat embolism was generated by reaming one femur and tibia, followed by pressurization of the canal. No difference was found in any parameters measured between supine and lateral positions at any time (0.126 < P < 0.856). The position of trauma patients undergoing reamed intramedullary nailing did not alter the presentation of the features of the lung secondary to fat embolism.

Development of estimates of dietary nitrates, nitrites, and nitrosamines for use with the Short Willet Food Frequency Questionnaire.

Studies have suggested that nitrates, nitrites, and nitrosamines have an etiologic role in adverse pregnancy outcomes and chronic diseases such as cancer. Although an extensive body of literature exists on estimates of these compounds in foods, the extant data varies in quality, quantified estimates, and relevance. We developed estimates of nitrates, nitrites, and nitrosamines for food items listed in the Short Willet Food Frequency Questionnaire (WFFQ) as adapted for use in the National Birth Defects Prevention Study. Multiple reference databases were searched for published literature reflecting nitrate, nitrite, and nitrosamine values in foods. Relevant published literature was reviewed; only publications reporting results for items listed on the WFFQ were selected for inclusion. The references selected were prioritized according to relevance to the U.S. population. Based on our estimates, vegetable products contain the highest levels of nitrate, contributing as much as 189 mg/serving. Meat and bean products contain the highest levels of nitrites with values up to 1.84 mg/serving. Alcohol, meat and dairy products contain the highest values of nitrosamines with a maximum value of 0.531 microg/serving. The estimates of dietary nitrates, nitrites, and nitrosamines generated in this study are based on the published values currently available. To our knowledge, these are the only estimates specifically designed for use with the adapted WFFQ and generated to represent food items available to the U.S. population. The estimates provided may be useful in other research studies, specifically in those exploring the relation between exposure to these compounds in foods and adverse health outcomes.

The current review examined recent literature to determine our state of knowledge about the potential ability of physical activity serve as a protectant against drug abuse vulnerability. Both preclinical and clinical studies were examined using either associational or random assignment study designs. In addition to examining drug use as an outcome variable, the potential neural mediators linking physical activity and drug abuse vulnerability were examined. Several important conclusions may be drawn. First, the preclinical evidence is solid in showing that physical activity in various forms is able to serve as both a preventive and treatment intervention that reduces drug use, although voluntary alcohol drinking appears to be an exception to this conclusion. Second, the clinical evidence provides some evidence, albeit mixed, to suggest a beneficial effect of physical activity on tobacco dependent individuals. In contrast, there exists only circumstantial evidence that physical activity may reduce use of drugs other than nicotine, and there is essentially no solid information from random control studies to know if physical activity may prevent initiation of problem use. Finally, both preclinical and clinical evidence shows that various brain systems are altered by physical activity, with the medial prefrontal cortex (mPFC) serving as one potential node that may mediate the putative link between physical activity and drug abuse vulnerability. It is concluded that novel neurobehavioral approaches taking advantage of novel techniques for assessing the physiological impact of physical activity are needed and can be used to inform the longitudinal random control studies that will answer definitively the question posed.

Current perspectives and challenges in understanding the role of nitrite as an integral player in nitric oxide biology and therapy

PubMed Central

Vitturi, Dario A.; Patel, Rakesh P.

2011-01-01

Beyond an inert oxidation product of nitric oxide (NO) metabolism, current thinking posits a key role for nitrite as a mediator of NO-signaling, especially during hypoxia. This concept has been discussed both in the context of nitrite serving a role as an endogenous modulator of NO-homeostasis, but also from a novel clinical perspective whereby nitrite therapy may replete NO-signaling and prevent ischemic tissue injury. Indeed, the relatively rapid translation of studies delineating mechanisms of action to ongoing and planned clinical trials has been critical in fuelling interest in nitrite biology and several excellent reviews have been written on this topic. In this article we limit our discussions to current concepts, and what we feel are questions that remain unanswered within the paradigm of nitrite being a mediator of NO biology. PMID:21683783

Quantum dot as spin current generator and energy harvester

Szukiewicz, Barbara; Wysokiński, Karol I.

2015-05-01

The thermoelectric transport in the device composed of a central nanoscopic system in contact with two electrodes and subject to the external magnetic field of Zeeman type has been studied. The device can support pure spin current in the electrodes and may serve as a source of the temperature induced spin currents with possible applications in spintronics. The system may also be used as an energy harvester. We calculate its thermodynamic efficiency η and the power output P. The maximal efficiency of the device reaches the Carnot value when the device works reversibly but with the vanishing power. The interactions between carriers diminish the maximal efficiency of the device, which under the constant load drops well below the Carnot limit but may exceed the Curzon-Ahlborn limit. While the effect of intradot Coulomb repulsion on η depends on the parameters, the interdot/interlevel interaction strongly diminishes the device efficiency.

Lipids are one of the major subcellular components, and play numerous essential functions. As well as their physiological roles, oils stored in biomass are useful commodities for a variety of biotechnological applications including food, chemical feedstocks, and fuel. Due to their agronomic as well as economic and societal importance, lipids have historically been subjected to intensive studies. Major current efforts are to increase the energy density of cell biomass, and/or create designer oils suitable for specific applications. This chapter covers some basic aspects of what one needs to know about lipids: definition, structure, function, metabolism and focus is also given on the development of modern lipid analytical tools and major current engineering approaches for biotechnological applications. This introductory chapter is intended to serve as a primer for all subsequent chapters in this book outlining current development in specific areas of lipids and their metabolism.

State observer for synchronous motors

Lang, Jeffrey H.

1994-03-22

A state observer driven by measurements of phase voltages and currents for estimating the angular orientation of a rotor of a synchronous motor such as a variable reluctance motor (VRM). Phase voltages and currents are detected and serve as inputs to a state observer. The state observer includes a mathematical model of the electromechanical operation of the synchronous motor. The characteristics of the state observer are selected so that the observer estimates converge to the actual rotor angular orientation and velocity, winding phase flux linkages or currents.

Malnutrition in institutionalised elderly increases morbidity and care costs. Meat and dairy foods are high-quality protein sources so adequate intakes may reduce malnutrition risk. We aimed to determine whether inadequate intakes of meat and dairy foods contribute to malnutrition in institutionalised elderly. This cross-sectional study involved 215 elderly residents (70·2 % females, mean age 85·8 years) from twenty-one aged-care facilities in Melbourne, Australia. Dietary intake was assessed using observed plate waste. Food groups and serving sizes were based on the Australian Guide to Healthy Eating. Nutrient content was analysed using a computerised nutrient analysis software (Xyris). Malnutrition risk was assessed using the Mini Nutrition Assessment (MNA) tool; a score between 24 and 30 indicates normal nutritional status. Data were analysed using robust regression. Mean MNA score was 21·6 (sd 2·7). In total, 68 % of residents were malnourished or at risk of malnutrition (MNA score≤23·5). Protein intake was 87 (sd 28) % of the Australian recommended dietary intake (RDI). Consumption averaged 1 serving each of dairy foods and meat daily. Number of dairy and meat servings related to proportion of protein RDI (both P24 points). Provision of meat and dairy foods did not meet recommended levels. On the basis of current dietary intakes in aged-care residents, increasing consumption of dairy foods to the recommended four servings daily ensures protein adequacy and may reduce malnutrition risk in institutionalised elderly, and so reduce risk of comorbidities and costs associated with malnutrition.

Assertive Community Treatment (ACT) is an evidence-based practice for individuals with severe mental illness. Although at least half of all people with severe mental illness are parents, little is known about their experiences as parents and as recipients of mental health interventions like ACT. The purpose of the current study was to examine the experiences of parent consumers served by ACT. Seventeen parents being served by ACT teams were interviewed about parenting, parenting needs, severe mental illness, satisfaction with ACT services, and suggestions for improved parent-focused treatment services. All parents identified at least one positive aspect of parenting and most parents (77%) also identified negative aspects of parenting. Loss of custody emerged as a significant parenting problem, with most parents (88%) experiencing custody loss at least once. Parents expressed interest in numerous parent-focused services, including family therapy, parenting skills, communication skills training, resources for children, and peer support groups. Most participants with adult children (88%) reported having no unmet parent-related needs and high satisfaction (4.63 of 5) with ACT services, whereas parents with young children (78%) reported having several unmet parenting needs and relatively lower satisfaction (3.78 out of 5) with ACT services. The ACT treatment model may not be adequately serving parents of young, dependent children. Findings suggest the need for more attention and focus on parent consumers, including identification of parental status and improved parent-related treatment services and support.

2012-01-01

Background Strategies to increase fruit and vegetable consumption of preschool aged children are needed. Objectives Evaluate the independent effects of the following meal service strategies on intake of fruits and vegetables of preschool children: 1.) Serving fruits and vegetables in advance of other menu items as part of traditional family style meal service; and 2.) Serving meals portioned and plated by providers. Methods Fifty-three preschool aged children completed a randomized crossover experiment conducted at a Head Start center in Minneapolis, MN. Over a six week trial period each of the experimental meal service strategies (serving fruits and vegetable first and serving meals portioned by providers) was implemented during lunch service for two one-week periods. Two one-week control periods (traditional family style meal service with all menu items served at once) were also included over the six week trial period. Childrens lunch intake was observed as a measure of food and nutrient intake during each experimental condition. Results Fruit intake was significantly higher (p<0.01) when fruits and vegetables were served in advance of other meal items (0.40 servings/meal) compared to the traditional family style meal service control condition when they were served in tandem with other menu items (0.32 servings/meal). Intakes of some nutrients found in fruits (vitamin A and folate) were concomitantly higher. In contrast, fruit and vegetable intakes were significantly lower and energy intake significantly higher during the provider portioned compared with control condition. Conclusions Serving fruits in advance of other meal items may be a low cost easy to implement strategy for increasing fruit intake in young children. However, serving vegetables first does not appear to increase vegetable intake. Results provide support for current recommendations for traditional family style meal service in preschool settings.

Biofilms formation capacities of Shewanella species in microbial fuel cells (MFCs) and their roles in current generation have been documented to be species-dependent. Understandings of the biofilms growth and metabolism are essential to optimize the current generation of MFCs. Shewanella decolorationis S12 was used in both closed-circuit and open-circuit MFCs in this study. The anodic S. decolorationis S12 biofilms could generate fivefold more current than the planktonic cells, playing a dominant role in current generation. Anodic biofilms viability was sustained at 98 ± 1.2% in closed-circuit while biofilms viability in open-circuit decreased to 72 ± 7% within 96 h. The unviable domain in open-circuit MFCs biofilms majorly located at the inner layer of biofilm. The decreased biofilms viability in open-circuit MFCs could be recovered by switching into closed-circuit, indicating that the current-generating anode in MFCs could serve as a favorable electron acceptor and provide sufficient energy to support cell growth and metabolism inside biofilms.

Champagne, Katelynn; Burkhouse, Katie L; Woody, Mary L; Feurer, Cope; Sosoo, Effua; Gibb, Brandon E

2016-10-01

The current study examined whether overgeneral autobiographical memory (OGM) bias serves as a state-like marker of major depressive disorder (MDD) in adolescence or whether it would also be observed in currently nondepressed adolescents with a history of MDD. We examined differences in OGM to positive and negative cue words between adolescents (aged 11-18 years) with current MDD (n = 15), remitted MDD (n = 25), and no history of any depressive disorder (n = 25). Youth and their parents were administered a structured diagnostic interview and adolescents completed the autobiographical memory test. Compared to never depressed adolescents, adolescents with current or remitted MDD recalled less specific memories in response to positive and negative cue words. The difference between the two MDD groups was small and nonsignificant. These findings suggest that OGM is not simply a state-like marker in currently depressed adolescents, but is also evident in adolescents with remitted MDD, indicating that it may represent a trait-like vulnerability that increases risk for relapse.

Pilot infrastructures are becoming prominent players in the Grid environment. One of the major advantages is represented by the reduced effort required by the user communities (also known as Virtual Organizations or VOs) due to the outsourcing of the Grid interfacing services, i.e. the pilot factory, to Grid experts. One such pilot factory, based on the glideinWMS pilot infrastructure, is being operated by the Open Science Grid at University of California San Diego (UCSD). This pilot factory is serving multiple VOs from several scientific domains. Currently the three major clients are the analysis operations of the HEP experiment CMS, the community VO HCC, which serves mostly math, biology and computer science users, and the structural biology VO NEBioGrid. The UCSD glidein factory allows the served VOs to use Grid resources distributed over 150 sites in North and South America, in Europe, and in Asia. This paper presents the steps taken to create a production quality pilot factory, together with the challenges encountered along the road.

2007-03-01

Only a few studies have found competence skills to be a protective factor against adolescent alcohol use; others did not find a direct effect on alcohol. A possible reason for this is that competence skills may moderate the effects of risk factors for alcohol use and that aspect has not been examined often or in a longitudinal design. This study tested whether several competence skills served either as direct protective factors against alcohol use or moderators of the impact of social risk factors on alcohol use. Participants (N = 1318) completed questionnaires that included measures of decision-making skills, refusal skill techniques, resisting media influences, friends' drinking and perceived social benefits of drinking, as well as current drinking amount and future drinking at baseline, one-year follow-up and two-year follow-up. Data analyses were conducted using multi-level mixed effects generalized linear models with random intercept. All the competence skills and the risk factors predicted current and future drinking. Several significant interactions were found between (1) perceived social benefits of drinking and decision-making skills, (2) perceived social benefits of drinking and refusal skill techniques and (3) friends' drinking and refusal skill techniques. Competence skills served as protective factors, as well as moderators. One possible reason that competence enhancement approaches to alcohol prevention are effective may be due to the inclusion of the competence skills component.

High-precision {beta} decay half-life measurements of proton-rich nuclei for testing the CVC hypothesis

The experimental study of super-allowed nuclear {beta} decays serves as a sensitive probe of the conservation of the weak vector current (CVC) and allows tight limits to be set on the presence of scalar or right-handed currents. Once CVC is verified, it is possible to determine the V{sub ud} element of the CKM quark-mixing matrix. Similarly, the study of nuclear mirror {beta} decays allows to arrive at the same final quantity V{sub ud}. Whereas dedicated studies of 0{sup +}{yields}0{sup +} decays are performed for several decades now, the potential of mirror transitions was only rediscovered recently. Therefore, it can bemore » expected that important progress is possible with high-precision studies of different mirror {beta} decays.

Stainless steel is widely used in nuclear power plants, such as various high-radioactive pool, tools storage and fuel transportation channel, and serves as an important barrier to stop the leakage of high-radioactive material. NonDestructive Evaluation (NDE) methods, eddy current testing (ET), ultrasonic examination (UT), penetration testing (PT) and hybrid detection method, etc., have been introduced into the inspection of a nuclear plant. In this paper, the Alternating Current Field Measurement (ACFM) was fully applied to detect and evaluate the defects in the welds of the stainless steel. Simulations were carried out on different defect types, crack lengths, and orientation to reveal the relationship between the signals and dimensions to determine whether methods could be validated by the experiment. A 3-axis ACFM probe was developed and three plates including 16 defects, which served in nuclear plant before, were examined by automatic detection equipment. The result shows that the minimum detectable crack length on the surface is 2mm and ACFM shows excellent inspection results for a weld in stainless steel and gives an encouraging prospect of broader application.

New Molecular Targets for Antiepileptic Drugs: α2δ, SV2A, and Kv7/KCNQ/M Potassium Channels

PubMed Central

2008-01-01

Many currently prescribed antiepileptic drugs (AEDs) act via voltage-gated sodium channels, through effects on γ-aminobutyric acid–mediated inhibition, or via voltage-gated calcium channels. Some newer AEDs do not act via these traditional mechanisms. The molecular targets for several of these nontraditional AEDs have been defined using cellular electrophysiology and molecular approaches. Here, we describe three of these targets: α2δ, auxiliary subunits of voltage-gated calcium channels through which the gabapentinoids gabapentin and pregabalin exert their anticonvulsant and analgesic actions; SV2A, a ubiquitous synaptic vesicle glycoprotein that may prepare vesicles for fusion and serves as the target for levetiracetam and its analog brivaracetam (which is currently in late-stage clinical development); and Kv7/KCNQ/M potassium channels that mediate the M-current, which acts a brake on repetitive firing and burst generation and serves as the target for the investigational AEDs retigabine and ICA-105665. Functionally, all of the new targets modulate neurotransmitter output at synapses, focusing attention on presynaptic terminals as critical sites of action for AEDs. PMID:18590620

The acquisition of mechano-electrical transducer current adaptation in auditory hair cells requires myosin VI.

The transduction of sound into electrical signals occurs at the hair bundles atop sensory hair cells in the cochlea, by means of mechanosensitive ion channels, the mechano-electrical transducer (MET) channels. The MET currents decline during steady stimuli; this is termed adaptation and ensures they always work within the most sensitive part of their operating range, responding best to rapidly changing (sound) stimuli. In this study we used a mouse model (Snell's waltzer) for hereditary deafness in humans that has a mutation in the gene encoding an unconventional myosin, myosin VI, which is present in the hair bundles. We found that in the absence of myosin VI the MET current fails to acquire its characteristic adaptation as the hair bundles develop. We propose that myosin VI supports the acquisition of adaptation by removing key molecules from the hair bundle that serve a temporary, developmental role. Mutations in Myo6, the gene encoding the (F-actin) minus end-directed unconventional myosin, myosin VI, cause hereditary deafness in mice (Snell's waltzer) and humans. In the sensory hair cells of the cochlea, myosin VI is expressed in the cell bodies and along the stereocilia that project from the cells' apical surface. It is required for maintaining the structural integrity of the mechanosensitive hair bundles formed by the stereocilia. In this study we investigate whether myosin VI contributes to mechano-electrical transduction. We report that Ca(2+) -dependent adaptation of the mechano-electrical transducer (MET) current, which serves to keep the transduction apparatus operating within its most sensitive range, is absent in outer and inner hair cells from homozygous Snell's waltzer mutant mice, which fail to express myosin VI. The operating range of the MET channels is also abnormal in the mutants, resulting in the absence of a resting MET current. We found that cadherin 23, a component of the hair bundle's transient lateral links, fails to be downregulated along the length of the stereocilia in maturing Myo6 mutant mice. MET currents of heterozygous littermates appear normal. We propose that myosin VI, by removing key molecules from developing hair bundles, is required for the development of the MET apparatus and its Ca(2+) -dependent adaptation. © 2016 The Authors.

We demonstrate that a current can be induced and switched in a sub-femtosecond time-scale in an insulating calcium fluoride single crystal by an intense optical field. This measurement indicates that a sizable current can be generated and also controlled by an optical field in a dielectric medium, implying the capability of rapid current switching at a rate of optical frequency, PHz (10{sup 15} Hz), which is a couple of orders of magnitude higher than that of contemporary electronic signal processing. This demonstration may serve to facilitate the development of ultrafast devices in PHz frequency.

Currently, the chemotherapeutic treatments for retinoblastoma are broad-based drugs such as vincristine, carboplatin, or etoposide. However, therapies targeted directly to aberrant signaling pathways may provide more effective therapy for this disease. The purpose of our study is to illustrate the relationship between the expressions of miRs-449a and -449b to retinoblastomamore » proliferation and apoptosis. We are the first to confirm an inhibitory effect of miR-449a and -449b in retinoblastoma by demonstrating significantly impaired proliferation and increased apoptosis of tumor cells when these miRNAs are overexpressed. This study suggests that these miRNAs could serve as viable therapeutic targets for retinoblastoma treatment.« less

The data used in this study was obtained from the Sloan Digital Sky Survey (SDSS), which provides astronomers with what is currently the most extensive mapping of the universe, covering 25% of the sky and cataloging the spectral properties (e.g., luminosity, color, surface temperature) of over 100 million celestial objects. Images generated by the SDSS are collected through 5 filters named u, g, r, l, and z that have respective wavelengths of 3540, 4750, 6222, 7632, and 9049 A. By measuring the photometric redshifts of the aforementioned wavelengths of a galaxy, astronomers can ascertain the extent to which galaxy is receding from which the distance to the galaxy can be calculated. Data collected for a small select group of galaxies (approximately 30, 000) contains accurate measurements of the galaxies' redshifts, in addition to measurements of their spectral properties. The above dataset containing both redshift measurements as well as spectral properties of the selected galaxies served as the training set for the purposes of this study; the data set containing only the spectra properties of a separate group of galaxies served as the test set.

Public health research requires sound design and thoughtful consideration of potential biases that may influence the validity of results. It also requires careful implementation of protocols and procedures that are likely to translate from the research environment to actual clinical practice. This article is the product of a breakout session from the 2009 Academic Emergency Medicine consensus conference entitled “Public Health in the ED: Screening, Surveillance, and Intervention” and serves to describe in detail aspects of performing emergency department (ED)-based public health research, while serving as a resource for current and future researchers. In doing so, the authors describe methodologic features of study design, participant selection and retention, and measurements and analyses pertinent to public health research. In addition, a number of recommendations related to research methods and future investigations related to public health work in the ED are provided. Public health investigators are poised to make substantial contributions to this important area of research, but this will only be accomplished by employing sound research methodology in the context of rigorous program evaluation.

This study examines the association between military service in Southeast Asia and alcohol drinking patterns in 2,169 male-male monozygotic twin pairs who both served on active military duty during the Vietnam era (1965-75). Data on alcohol drinking were collected in 1987 by mail and telephone interview. The alcohol drinking measures include three indicators of abstention (lifetime abstainer, lifetime non-regular drinker, and current abstainer) and two indicators of consumption (average daily ethanol consumption and high consumption). In unadjusted and co-twin adjusted analyses, neither service in Southeast Asia nor combat exposure was significantly associated with any measure of abstention. In the co-twin adjusted analysis, there was no association of Southeast Asia service and combat exposure with average daily ethanol consumption. After adjustment for co-twin effects, 4.0 percent of non-Southeast Asia veterans were high consumers compared to 6.7 percent of Southeast Asia veterans who served in high combat. We conclude that prior military service in a war zone has a relatively modest long-term effect on the alcohol drinking patterns of male veterans. PMID:2327534

The present study was aimed at evaluating the number of bacteria and mould fungi in the indoor and outdoor environment of Toruń University Library. The sampling sites were located in the rooms serving the functions typical of libraries (i.e. in the Main Reading Room, Current Periodicals Reading Room, Collections Conservation Laboratory, Old Prints Storeroom, in rooms serving other (non-library) functions (i.e. main hall, cafeteria, and toilet) as well as outside the library building. The analyses reveal that the concentrations of bacterial as well as fungal aerosols estimated with the use of the impaction method ranged between 10(1)-10(3) CFU·m(-3), which corresponds to the concentrations normally observed in areas of this kind. Evaluation of the hygienic condition of the studied areas was based on the criteria for microbiological cleanliness in interiors submitted by the European Commission in 1993. According to this classification, the air was considered to be heavily or moderately contaminated with bacteria, while the air contamination with mould fungi was described as low or moderate. The air in the Old Prints Storeroom was considered the least contaminated with microbial aerosol.

Impact of Inner Surface Perturbations on the Stability of Cylindrical Liner Implosion

NASA Astrophysics Data System (ADS)

Weis, Matthew; Peterson, Kyle; Hess, Mark; Lau, Y. Y.; Zhang, Peng; Gilgenbach, Ronald

2015-11-01

This paper studies the effects of initial perturbations on the inner liner surface (ILS) of an imploding cylindrical liner. In MagLIF, nonuniform preheat of the fuel could provide an additional source of spatial nonuniformity on the ILS. A blast wave generated by the laser preheat might trigger the Richtmyer-Meshkov instability (RM) on the ILS which then serves as another seed to the Rayleigh-Taylor instability (RT) during the stagnation (deceleration) phase of the implosion. Another scenario is that the shock initiated from the outer liner surface, during current rise, propagates inward and is reflected at the ILS. This reflected shock would carry the initial ILS perturbations which then serve as an additional seed for the magneto-RT (MRT) during the acceleration phase of the implosion. These potentially dangerous interactions are analyzed using the 2D HYDRA code. The effects of axial magnetic fields, of the initial surface roughness spectrum, and of gas fill or water fill (to examine deceleration phase RT) are studied. M. R.

Considerable heterogeneity exists in adolescent substance use development. To most effectively prevent use, distinct trajectories of use must be identified as well as differential associations with predictors of use, such as leisure experience. The current study used a person-centered approach to identify distinct substance use trajectories and how leisure is associated with trajectory classes. Data came from a larger efficacy trial of 2.249 South African high school students who reported substance use at any time across 8 waves. Growth mixture modeling was used to identify developmental trajectories of substance use and the influence of healthy leisure. Results identified three increasing and one stable substance use trajectory and subjective healthy leisure served to protect against use. This study is the first of its kind to focus on a sample of South African adolescents and serves to develop a richer understanding of substance use development and the role of healthy leisure.

The Institute of Medicine's Future of Nursing report advocates for full nurse leader representation across multiple settings to address current challenges in our health care system. The purpose of this study was to examine nursing leadership development needs among Kansas registered nurses (RNs). Data were collected through an online survey and analyzed using quantitative and qualitative methods. Nearly 1,000 Kansas RNs participated. Most reported holding one or more leadership positions. Prevalent leadership goals were health care organization volunteer administrative roles. The most frequently identified barrier to developing leadership roles was time constraints. Many wanted to develop skills to serve on a board, 20% were interested in personal leadership development, and 19% in policy development. Based on the findings, the Kansas Action Coalition leadership team is developing programs to address the leadership needs of Kansas RNs. By building capacity in advanced leadership roles, RNs will be better prepared serve as full partners and lead efforts to promote the health of Kansans. Copyright © 2015 Elsevier Inc.

Language at Three Timescales: The Role of Real-Time Processes in Language Development and Evolution.

PubMed

McMurray, Bob

2016-04-01

Evolutionary developmental systems (evo-devo) theory stresses that selection pressures operate on entire developmental systems rather than just genes. This study extends this approach to language evolution, arguing that selection pressure may operate on two quasi-independent timescales. First, children clearly must acquire language successfully (as acknowledged in traditional evo-devo accounts) and evolution must equip them with the tools to do so. Second, while this is developing, they must also communicate with others in the moment using partially developed knowledge. These pressures may require different solutions, and their combination may underlie the evolution of complex mechanisms for language development and processing. I present two case studies to illustrate how the demands of both real-time communication and language acquisition may be subtly different (and interact). The first case study examines infant-directed speech (IDS). A recent view is that IDS underwent cultural to statistical learning mechanisms that infants use to acquire the speech categories of their language. However, recent data suggest is it may not have evolved to enhance development, but rather to serve a more real-time communicative function. The second case study examines the argument for seemingly specialized mechanisms for learning word meanings (e.g., fast-mapping). Both behavioral and computational work suggest that learning may be much slower and served by general-purpose mechanisms like associative learning. Fast-mapping, then, may be a real-time process meant to serve immediate communication, not learning, by augmenting incomplete vocabulary knowledge with constraints from the current context. Together, these studies suggest that evolutionary accounts consider selection pressure arising from both real-time communicative demands and from the need for accurate language development.

Current-Driven Dynamics of Skyrmions Stabilized in MnSi Nanowires Revealed by Topological Hall Effect

NASA Astrophysics Data System (ADS)

Liang, Dong; Degrave, John; Stolt, Matthew; Tokura, Yoshinori; Jin, Song

2015-03-01

Skyrmions, novel topologically stable spin vortices, hold promise for next-generation high-density magnetic storage technologies due to their nanoscale domains and ultralow energy consumption. One-dimensional (1D) nanowires are ideal hosts for skyrmions since they not only serve as a natural platform for magnetic racetrack memory devices but also can potentially stabilize skyrmions. We use the topological Hall effect (THE) to study the phase stability and current-driven dynamics of the skyrmions in MnSi nanowires. The THE was observed in an extended magnetic field-temperature window (15 to 30 K), suggesting stabilization of skyrmion phase in nanowires compared with the bulk (27 to 29.5 K). Furthermore, we study skyrmion dynamics in this extended skyrmion phase region and found that under the high current-density of 108-109Am-2 enabled by nanowire geometry, the THE decreases with increasing current densities, which demonstrates the current-driven motion of skyrmions generating the emergent electric field. These results open up the exploration of nanowires as an attractive platform for investigating skyrmion physics in 1D systems and exploiting skyrmions in magnetic storage concepts.

Excavating silences and tensions of agency|passivity in science education reform

NASA Astrophysics Data System (ADS)

Rivera Maulucci, Maria S.

2010-12-01

I reflect on studies by Rodriguez and Carlone, Haun-Frank, and Kimmel to emphasize the ways in which they excavate silences in the science education literature related to linguistic and cultural diversity and situating the problem of reform in teachers rather than contextual factors, such as traditional schooling discourses and forces that serve to marginalize science. I propose that the current push for top-down reform and accountability diminishes opportunities for receptivity, learning with and from students in order to transform teachers' practices and promote equity in science education. I discuss tensions of agency and passivity in science education reform and argue that attention to authentic caring constitutes another silence in the science education literature. I conclude that the current policy context positions teachers and science education researchers as tempered radicals struggling against opp(reg)ressive reforms and that there is a need for more studies to excavate these and other silences.

Theory and practice in sport psychology and motor behaviour needs to be constrained by integrative modelling of brain and behaviour.

PubMed

Keil, D; Holmes, P; Bennett, S; Davids, K; Smith, N

2000-06-01

Because of advances in technology, the non-invasive study of the human brain has enhanced the knowledge base within the neurosciences, resulting in an increased impact on the psychological study of human behaviour. We argue that application of this knowledge base should be considered in theoretical modelling within sport psychology and motor behaviour alongside existing ideas. We propose that interventions founded on current theoretical and empirical understanding in both psychology and the neurosciences may ultimately lead to greater benefits for athletes during practice and performance. As vehicles for exploring the arguments of a greater integration of psychology and neurosciences research, imagery and perception-action within the sport psychology and motor behaviour domains will serve as exemplars. Current neuroscience evidence will be discussed in relation to theoretical developments; the implications for sport scientists will be considered.

Stellar winds and planetary bodies simulations: Magnetized obstacles in super-Alfvénic and sub-Alfvénic flows

NASA Astrophysics Data System (ADS)

Vernisse, Y.; Riousset, J. A.; Motschmann, U.; Glassmeier, K.-H.

2017-03-01

Most planetary bodies are moving in the solar wind, in a stellar wind, or in a plasma flow within the magnetosphere of a planet. The interaction of the body with the flowing plasma provides us with various interaction types, which mainly depend on the flow speed, the magnetization of the body, its conductivity, the presence of an ionosphere, and the size of the body. We establish two cornerstones representing highly magnetized obstacles embedded in a super-Alfvénic and sub-Alfvénic plasma. Those two cornerstones complete the two cornerstones defined in our previous study on inert obstacles in super-Alfvénic and sub-Alfvénic regimes. Tracking the transitions between these cornerstones enable better understanding of the feedback of the obstacle onto the plasma flow. Each interaction is studied by means of the hybrid model simulation code AIKEF. The results are summarized in three dimensional diagrams showing the current structures, which serve as a basis for our descriptions. We identify the major currents such as telluric, magnetosonic, Chapman-Ferraro, and bow-shock currents as the signatures of the particular state of development of the interaction region. We show that each type of interactions can be identified by studying the shape and the magnitude of its specific currents.

Consumers may not have given much thought to who supplies their electricity, or how, but they should know that a tremendous battle is being waged behind their electrical sockets. Just as several long-distance telecommunication carriers (AT&T, Spring, MCI) now compete to serve each household, so too firms with currently unfamiliar names may one day - in the not-so-distant future - be competing to supply household electricity. Whether, when, and how this happens are questions at the center of a vigorous debate occurring in Washington, in state capitals, and in courtrooms around the United States. Many utilities, small consumer groups, andmore » environmentalists argue that moving to wide-open competition in electricity markets will benefit only the largest customers. With enhanced competition, what becomes of the electric utilities` historic obligation to serve? Customers and society may not be prepared to assume the risk that some customers could become, quite literally, powerless.« less

Arcjet nozzle design impacts

NASA Technical Reports Server (NTRS)

Curran, Francis M.; Sovie, Amy J.; Haag, Thomas W.

1989-01-01

The effect of nozzle configuration on the operating characteristics of a low power dc arcjet thruster was determined. A conical nozzle with a 30 deg converging angle, a 20 deg diverging angle, and an area ratio of 225 served as the baseline case. Variations on the geometry included bell-shaped contours both up and downstream, and a downstream trumpet-shaped contour. The nozzles were operated over a range of specific power near that anticipated for on-orbit operation. Mass flow rate, thrust, current, and voltage were monitored to provide accurate comparisons between nozzles. The upstream contour was found to have minimal effect on arcjet operation. It was determined that the contour of the divergent section of the nozzle, that serves as the anode, was very important in determining the location of arc attachment, and thus had a significant impact on arcjet performance. The conical nozzle was judged to have the optimal current/voltage characteristics and produced the best performance of the nozzles tested.

Establishing a framework for a physician assistant/bioethics dual degree program.

Carr, Mark F; Bergman, Brett A

2014-01-01

: Numerous medical schools currently offer a master of arts (MA) in bioethics dual degree for physicians. A degree in bioethics enhances the care physicians provide to patients and prepares physicians to serve on ethics committees and consult services. Additionally, they may work on institutional and public policy issues related to ethics. Several physician assistant (PA) programs currently offer a master of public health (MPH) dual degree for PAs. A degree in public health prepares PAs for leadership roles in meeting community health needs. With the success of PA/MPH dual degree programs, we argue here that a PA/bioethics dual degree would be another opportunity to advance the PA profession and consider how such a program might be implemented. The article includes the individual perspectives of the authors, one of whom completed a graduate-level certificate in bioethics concurrently with his 2-year PA program, while the other served as a bioethics program director.

The plasma focus is a device that uses high voltage and electromagnetic force to induce plasma generation and acceleration, in order to cause nuclear reactions. Radiation of various types (X-ray, gamma ray, electrons, ions, neutrons) can be generated using this method during the pinch phase, thus making the plasma focus able to serve as a radiation source. Material testing, modification, and identification are among the current applications of the plasma focus. Other than being an alternative option to isotopic sources, the plasma focus, which requires multidisciplinary team of personnel to design, operate, and troubleshoot, can also serve as an excellent learning device for physics and engineering students in the fields including, but not limited to, plasma physics, nuclear physics, electronics engineering, and mechanical engineering. This work describes the parameters and current status of Thai Plasma Focus 1 (TPF-1) and the characteristics of the plasma being produced in the machine using a Rogowski coil.

Aeromechanics of the Spider Cricket Jump: How to Jump 60+ Times Your Body Length and Still Land on Your Feet

2015-11-01

Flapping, gliding, running, crawling and swimming have all been studied extensively in the past and have served as a source of inspiration for engineering designs. In the current project, we explore a mode of locomotion that straddles ground and air: jumping. The subject of our study is among the most proficient of long-jumpers in Nature: the spider cricket of the family Rhaphidophoridae, which can jump more than 60 times its body length. Despite jumping this immense distance, these crickets usually land on their feet, indicating an ability to control their posture during ``flight.'' We employ high-speed videogrammetry, to examine the jumps and to track the crickets' posture and appendage orientation throughout their jumps. Simple aerodynamic models are developed to predict the aerodynamic forces and moment on the crickets during `flight`. The analysis shows that these wingless insects employ carefully controlled and coordinated positioning of the limbs during flight so as to increase jump distance and to stabilize body posture during flight. The principles distilled from this study could serve as an inspiration for small jumping robots that can traverse complex terrains.

Salivary pH and Buffering Capacity as Risk Markers for Early Childhood Caries: A Clinical Study.

2015-01-01

The diagnostic utility of saliva is currently being explored in various branches of dentistry, remarkably in the field of caries research. This study was aimed to determine if assessment of salivary pH and buffering capacity would serve as reliable tools in risk prediction of early childhood caries (ECC). Paraffin-stimulated salivary samples were collected from 50 children with ECC (group I) and 50 caries free children (group II). Salivary pH and buffering capacity (by titration with 0.1 N hydrochloric acid) were assessed using a handheld digital pH meter in both groups. The data obtained were subjected to statistical analysis. Statistically, no significant difference was observed between both the groups for all salivary parameters assessed, except for the buffering capacity level at 150 μl titration of 0.1 N hydrochloric acid (p = 0.73; significant at 1% level). Salivary pH and buffering capacity may not serve as reliable markers for risk prediction of ECC. How to cite this article: Jayaraj D, Ganesan S.

Reduced Investment in Science: An Examination of the Current Federal Budget and a Case Study on Its Impact on the Scientific Community

2013-12-01

Federally funded scientific research is one of the building blocks of technological advancement and economic growth. This research can also lead to transformational ideas and discoveries. In our current fiscal environment, strategies to rein in federal spending have become a priority, although they have proven to be complex. The possible deals and negotiations to reduce federal spending may hinder the work of the scientific community to serve society. Since 2005 federal investment in research and development has slowed. The average annual growth in federal funding for scientific research from 2004 - 2009 was 0.9% as compared to 3.3% over the previous 20 years. What does the current budget situation mean for science? It means reductions in basic and applied research, interruptions in long-term monitoring and data collection, an inability to repair or build infrastructure, and less federal grant support for current and future scientists. I will first provide an update on the current federal budget situation and examples of how current policies are impacting the scientific community. Second, I will present a case study of the effect of reduced federal investment in science. Specifically, I will discuss how investments in research and development have far-reaching impacts on society and examine how reduced funding impairs valuable research efforts.

The effect of the labelled serving size on consumption: A systematic review.

Guidance for food consumption and portion control plays an important role in the global management of overweight and obesity. Carefully conceptualised serving size labelling can contribute to this guidance. However, little is known about the relationship between the information that is provided regarding serving sizes on food packages and levels of actual food consumption. The aim of this systematic review was to investigate how serving size information on food packages influences food consumption. We conducted a systematic review of the evidence published between 1980 and March 2018. Two reviewers screened titles and abstracts for relevance and assessed relevant articles for eligibility in full-text. Five studies were considered eligible for the systematic review. In three of the included studies, changes in serving size labelling resulted in positive health implications for consumers, whereby less discretionary foods were consumed, if serving sizes were smaller or if serving size information was provided alongside contextual information referring to the entire package. One study did not find significant differences between the conditions they tested and one study suggested a potentially negative impact, if the serving size was reduced. The influence of labelled serving size on consumption of non-discretionary foods remains unclear, which is partially due to the absence of studies specifically focusing on non-discretionary food groups. Studies that investigate the impact of serving size labels within the home environment and across a broad demographic cross-section are required. Copyright © 2018. Published by Elsevier Ltd.

To test whether reducing the standard serving size of alcoholic beverages would reduce voluntary alcohol consumption in a laboratory (study 1) and a real-world drinking environment (study 2). Additionally, we modelled the potential public health benefit of reducing the standard serving size of on-trade alcoholic beverages in the United Kingdom. Studies 1 and 2 were cluster-randomized experiments. In the additional study, we used the Sheffield Alcohol Policy Model to estimate the number of deaths and hospital admissions that would be averted per year in the United Kingdom if a policy that reduces alcohol serving sizes in the on-trade was introduced. A semi-naturalistic laboratory (study 1), a bar in Liverpool, UK (study 2). Students and university staff members (study 1: n = 114, mean age = 24.8 years, 74.6% female), residents from local community (study 2: n = 164, mean age = 34.9 years, 57.3% female). In study 1, participants were assigned randomly to receive standard or reduced serving sizes (by 25%) of alcohol during a laboratory drinking session. In study 2, customers at a bar were served alcohol in either standard or reduced serving sizes (by 28.6-33.3%). Outcome measures were units of alcohol consumed within 1 hour (study 1) and up to 3 hours (study 2). Serving size condition was the primary predictor. In study 1, a 25% reduction in alcohol serving size led to a 20.7-22.3% reduction in alcohol consumption. In study 2, a 28.6-33.3% reduction in alcohol serving size led to a 32.4-39.6% reduction in alcohol consumption. Modelling results indicated that decreasing the serving size of on-trade alcoholic beverages by 25% could reduce the number of alcohol-related hospital admissions and deaths per year in the United Kingdom by 4.4-10.5% and 5.6-13.2%, respectively. Reducing the serving size of alcoholic beverages in the United Kingdom appears to lead to a reduction in alcohol consumption within a single drinking occasion. © 2018 The Authors.

Coggins, Porter E.

2015-04-01

The purpose of this paper is (1) to present how general education elementary school age students constructed computer passwords using digital root sums and second-order arithmetic sequences, (2) argue that computer password construction can be used as an engaging introduction to generate interest in elementary school students to study mathematics related to computer science, and (3) share additional mathematical ideas accessible to elementary school students that can be used to create computer passwords. This paper serves to fill a current gap in the literature regarding the integration of mathematical content accessible to upper elementary school students and aspects of computer science in general, and computer password construction in particular. In addition, the protocols presented here can serve as a hook to generate further interest in mathematics and computer science. Students learned to create a random-looking computer password by using biometric measurements of their shoe size, height, and age in months and to create a second-order arithmetic sequence, then converted the resulting numbers into characters that become their computer passwords. This password protocol can be used to introduce students to good computer password habits that can serve a foundation for a life-long awareness of data security. A refinement of the password protocol is also presented.

Sex differences in stress-induced visceral hypersensitivity following early life adversity: a two hit model.

PubMed

Prusator, D K; Greenwood-Van Meerveld, B

2016-12-01

Early life adversity (ELA) has been indicated as a risk factor for the development of stress axis dysfunction in adulthood, specifically in females. We previously showed that unpredictable ELA induces visceral hyperalgesia in adult female rats. It remains to be determined whether ELA alters visceral nociceptive responses to stress in adulthood. The current study tested the hypothesis that following ELA, exposure to an adulthood stressor, or second hit, serves as a risk factor for exaggerated stress-induced visceral hypersensitivity that is sex-specific. Following ELA, adult stress was induced via a single exposure (acute) or repetitive daily exposure, 1 h/day for 7 days (chronic), to water avoidance stress (WAS). Acute WAS increased pain behaviors in all adult female rats, however, females that experienced unpredictable ELA exhibited significantly more pain behaviors compared to those exposed to predictable ELA or controls. Following chronic WAS, all adult females exhibited increased pain responses, however, an exaggerated response was observed in rats exposed to unpredictable or predictable ELA compared to controls. Similarly, in adult male rats exposure to acute or chronic WAS increased pain behaviors, however, there were no differences in pain behaviors between ELA groups. This study highlights a novel consequence of ELA on stress-induced visceral nociception in adulthood that is sex-specific. More importantly, our study suggests that ELA not only serves as a risk factor for development of chronic pain in adulthood, but also serves as a predisposition for worsening of visceral pain following adult stress in female rats. © 2016 John Wiley & Sons Ltd.

Current DG policies have fostered growth but need to be modernized to serve current needs and accommodate higher penetration levels. In this report, NREL summarizes international DG policy experiences and best practices and identifies the potential opportunities for policy reform.

Effect of a Second, Parallel Capacitor on the Performance of a Pulse Inductive Plasma Thruster

NASA Technical Reports Server (NTRS)

Polzin, Kurt A.; Balla, Joseph V.

2010-01-01

Pulsed inductive plasma accelerators are electrodeless space propulsion devices where a capacitor is charged to an initial voltage and is then discharged through an inductive coil that couples energy into the propellant, ionizing and accelerating it to produce thrust. A model that employs a set of circuit equations (as illustrated in Fig. 1a) coupled to a one-dimensional momentum equation has been previously used by Lovberg and Dailey [1] and Polzin et al. [2-4] to model the plasma acceleration process in pulsed inductive thrusters. In this paper an extra capacitor, inductor, and resistor are added to the system in the manner illustrated in the schematic shown in Fig. 1b. If the second capacitor has a smaller value than the initially charged capacitor, it can serve to increase the current rise rate through the inductive coil. Increasing the current rise rate should serve to better ionize the propellant. The equation of motion is solved to find the effect of an increased current rise rate on the acceleration process. We examine the tradeoffs between enhancing the breakdown process (increasing current rise rate) and altering the plasma acceleration process. These results provide insight into the performance of modified circuits in an inductive thruster, revealing how this design permutation can affect an inductive thruster's performance.

Sulfur oxidation to sulfate coupled with electron transfer to electrodes by Desulfuromonas strain TZ1

Zhang, T; Bain, TS; Barlett, MA

2014-01-02

Microbial oxidation of elemental sulfur with an electrode serving as the electron acceptor is of interest because this may play an important role in the recovery of electrons from sulfidic wastes and for current production in marine benthic microbial fuel cells. Enrichments initiated with a marine sediment inoculum, with elemental sulfur as the electron donor and a positively poised (+300 mV versus Ag/AgCl) anode as the electron acceptor, yielded an anode biofilm with a diversity of micro-organisms, including Thiobacillus, Sulfurimonas, Pseudomonas, Clostridium and Desulfuromonas species. Further enrichment of the anode biofilm inoculum in medium with elemental sulfur as the electronmore » donor and Fe(III) oxide as the electron acceptor, followed by isolation in solidified sulfur/Fe(III) medium yielded a strain of Desulfuromonas, designated strain TZ1. Strain TZ1 effectively oxidized elemental sulfur to sulfate with an anode serving as the sole electron acceptor, at rates faster than Desulfobulbus propionicus, the only other organism in pure culture previously shown to oxidize S with current production. The abundance of Desulfuromonas species enriched on the anodes of marine benthic fuel cells has previously been interpreted as acetate oxidation driving current production, but the results presented here suggest that sulfur-driven current production is a likely alternative.« less

Disruption of Helmet Streamers by Current Emergence

NASA Technical Reports Server (NTRS)

Guo, W. P.; Wu, S. T.; Tandberg-Hanssen, E.

1996-01-01

We have investigated the dynamic response of a coronal helmet streamer to the emergence from below of a current with its magnetic field in a direction opposite to the overlying streamer field. Once the emerging current moves into the closed region of the streamer, a current sheet forms between the emerging field and the streamer field, because the preexisting field and the newly emerging field have opposite polarities. Thus magnetic reconnection will occur at the flanks of the emerged structure where the current density is maximum. If the emerging current is large enough, the energy contained in the current and the reconnection will promptly disrupt the streamer. If the emerging current is small, the streamer will experience a stage of slow evolution. In this stage, slow magnetic reconnection occurring at the flanks of the emerged structure leads to the degeneration of the emerged current to a neutral point. Above this point, a new magnetic bubble will form. The resulting configuration resembles an inverse-polarity prominence. Depending on the initial input energy of the current, the resulting structure will either remain in situ, forming a quasi-static structure, or move upward, forming a coronal transient similar to coronal jets. The numerical method used in this paper can be used to construct helmet streamers containing a detached magnetic structure in their closed field region. The quasi-static solution may serve as a preevent corona for studying coronal mass ejection initiation.

For many men, the treatment of sexual dysfunctions such as premature ejaculation may well be most effective when pharmacotherapy is combined with psychotherapy. Yet the essential elements of psychotherapy that might best be combined with pharmacological-based therapy are currently unknown. Support for evidence-based studies that identify key components of psychotherapy that might improve positive long-term outcomes, including patient satisfaction, are needed. Pharmaceutical companies having a vested interest in achieving both treatment adherence and improved patient outcomes could benefit from such information.

West Nile virus remains the most common cause of arboviral encephalitis in North America. Since it was introduced, it has undergone adaptive genetic change as it spread throughout the continent. The WNV transmission cycle is relatively tractable in the laboratory. Thus the virus serves as a convenient model system for studying the population biology of mosquito-borne flaviviruses as they undergo transmission to and from mosquitoes and vertebrates. This review summarizes the current knowledge regarding the population dynamics of this virus within mosquito vectors. Copyright © 2016 Elsevier B.V. All rights reserved.

Entanglement properties are studied in the continuous-variable system of three nitrogen-vacancy center ensembles cou-pled to separate transmission line resonators interconnected by current-biased Josephson junction. The circuit is enhanced by Josephson parametric amplifier, which serves as source of squeezed microwave field. Bosonic modes of nitrogen-vacancy-center ensembles exhibit steady state entanglement for certain range of parameters. Squeezed microwave field can be consider as a driving force of entanglement. Proposed scheme provides generating entanglement for each of the three pairs of spin ensembles.

Preschool children's sensitivity to teacher-served portion size is linked to age related differences in leftovers.

2017-07-01

A strong predictor of children's food intake at a meal is the amount they are served, and with a high percentage children attending preschool, there is a need to consider the relationship between portion size and intake in this context. In a two-part repeated measures study we investigated whether the portions teachers serve to children i) differ from those children would serve themselves and ii) impact food intake at a local preschool in Singapore. Part 1 (n = 37, 20 boys, 3.0-6.8 years) compared the quantity of food served, consumed and leftover across three serving methods: 'regular' teacher-serving; child self-served portions; and a deliberately large portion served by the teacher (150% of each child's average previous gram intake). Part 2 (n = 44, 23 boys, 2.4-6.2 years old) consisted of three additional observations of school-based servings outside of the experimental manipulation and enhance external validity of the study findings. Results indicated that serving size and intake was similar when the children and teachers served their 'regular' portions, but children consumed most overall when the teacher served the larger 150% portion. This was dependent on the child's age, with the oldest children being most responsive to the large portions while the youngest children tended to serve and consume a similar weight of food, regardless of the serving method. Though the younger children were generally served less than the older children, they consistently had more leftovers across all of the study observations. These data suggest that younger preschool children moderated food intake by leaving food in their bowl, and emphasise the unique influence of caregivers over children's eating behaviours outside of the home environment.

Superconducting-circuit quantum heat engine with frequency resolved thermal baths

NASA Astrophysics Data System (ADS)

Hofer, Patrick P.; Souquet, Jean-René; Clerk, Aashish A.

The study of quantum heat engines promises to unravel deep, fundamental concepts in quantum thermodynamics. With this in mind, we propose a novel, realistic device that efficiently converts heat into work while maintaining reasonably large output powers. The key concept in our proposal is a highly peaked spectral density in both the thermal baths as well as the working fluid. This allows for a complete separation of the heat current from the working fluid. In our setup, Cooper pairs tunnelling across a Josephson junction serve as the the working fluid, while two resonant cavities coupled to the junction act as frequency-resolved thermal baths. The device is operated such that a heat flux carried entirely by the photons induces an electrical current against a voltage bias, providing work.

Frequency-tunable superconducting resonators via nonlinear kinetic inductance

Vissers, M. R.; Hubmayr, J.; Sandberg, M.; Chaudhuri, S.; Bockstiegel, C.; Gao, J.

2015-08-01

We have designed, fabricated, and tested a frequency-tunable high-Q superconducting resonator made from a niobium titanium nitride film. The frequency tunability is achieved by injecting a DC through a current-directing circuit into the nonlinear inductor whose kinetic inductance is current-dependent. We have demonstrated continuous tuning of the resonance frequency in a 180 MHz frequency range around 4.5 GHz while maintaining the high internal quality factor Qi > 180 000. This device may serve as a tunable filter and find applications in superconducting quantum computing and measurement. It also provides a useful tool to study the nonlinear response of a superconductor. In addition, it may be developed into techniques for measurement of the complex impedance of a superconductor at its transition temperature and for readout of transition-edge sensors.

Micro-drinking behaviours and consumption of wine in different wine glass sizes: a laboratory study.

PubMed

Zupan, Z; Pechey, R; Couturier, D L; Hollands, G J; Marteau, T M

2017-06-12

Tableware size may influence how much food and non-alcoholic drink is consumed. Preliminary evidence of the impact of glass size on purchasing of alcoholic drinks shows an increase in wine sales of almost 10% when the same portion of wine is served in a larger glass. The primary aim of the current study is to test if micro-drinking behaviours act as a mechanism that could underlie this effect, through an increase in drinking rate, sip duration and/or number of sips from a larger glass. In a between-subjects experimental design, 166 young women were randomised to drink a 175 ml portion of wine from either a smaller (250 ml) or larger (370 ml) wine glass. Primary outcomes were three micro-drinking behaviours, assessed observationally using video recordings: drinking rate, sip number and sip duration. Other possible mechanisms examined were satisfaction with the perceived amount of wine served and pleasure of the drinking experience, assessed using self-report measures. Wine drunk from the larger, compared with the smaller glass, was consumed more slowly and with shorter sip duration, counter to the hypothesised direction of effect. No differences were observed in any of the other outcome measures. These findings provide no support for the hypothesised mechanisms by which serving wine in larger wine glasses increases consumption. While micro-drinking behaviours may still prove to be a mechanism explaining consumption from different glass sizes, cross-validation of these results in a more naturalistic setting is needed.

Warm thanks: gratitude expression facilitates social affiliation in new relationships via perceived warmth.

PubMed

Williams, Lisa A; Bartlett, Monica Y

2015-02-01

Recent theorizing on the nature and function of gratitude (the find-remind-and-bind theory; Algoe, 2012) stipulates that expressing gratitude should serve to alert previously unacquainted peers to the potential for a high-quality social bond (i.e., a find function). Although the logic of this premise is supported by extant research, it has not, as yet, been tested empirically. In the current study, participants received a note from a previously unacquainted peer that contained an expression of gratitude (or did not) with regard to prior benefits provided by the participant. After providing ratings of the peer and ostensibly completing the study, participants were given an opportunity to spontaneously give their contact information to the peer, which served as a behavioral measure of affiliation. In line with the proposed find function of gratitude expressions, recipients of expressions of gratitude were more likely to extend the effort to continue the relationship with the novel peer by providing that peer with a means to contact them. This experiment also provided evidence that perceptions of interpersonal warmth (e.g., friendliness, thoughtfulness) serve as the mechanism via which gratitude expressions facilitate affiliation: insofar as gratitude expressions signaled interpersonal warmth of the expresser, they prompted investment in the burgeoning social bond. As such, these findings provide the first empirical evidence regarding 1 of the 3 central premises of the find-remind-and-bind theory of gratitude (Algoe, 2012) in the context of novel relationships.

Current practices in library/informatics instruction in academic libraries serving medical schools in the western United States: a three-phase action research study

PubMed Central

2013-01-01

Background To conduct a systematic assessment of library and informatics training at accredited Western U.S. medical schools. To provide a structured description of core practices, detect trends through comparisons across institutions, and to identify innovative training approaches at the medical schools. Methods Action research study pursued through three phases. The first phase used inductive analysis on reported library and informatics skills training via publicly-facing websites at accredited medical schools and the academic health sciences libraries serving those medical schools. Phase Two consisted of a survey of the librarians who provide this training to undergraduate medical education students at the Western U.S. medical schools. The survey revealed gaps in forming a complete picture of current practices, thereby generating additional questions that were answered through the Phase Three in-depth interviews. Results Publicly-facing websites reviewed in Phase One offered uneven information about library and informatics training at Western U.S. medical schools. The Phase Two survey resulted in a 77% response rate. The survey produced a clearer picture of current practices of library and informatics training. The survey also determined the readiness of medical students to pass certain aspects of the United States Medical Licensure Exam. Most librarians interacted with medical school curricular leaders through either curricula committees or through individual contacts. Librarians averaged three (3) interventions for training within the four-year curricula with greatest emphasis upon the first and third years. Library/informatics training was integrated fully into the respective curricula in almost all cases. Most training involved active learning approaches, specifically within Problem-Based Learning or Evidence-Based Medicine contexts. The Phase Three interviews revealed that librarians are engaged with the medical schools' curricular leaders, they are respected for their knowledge and teaching skills, and that they need to continually adapt to changes in curricula. Conclusions This study offers a long overdue, systematic view of current practices of library/informatics training at Western U.S. medical schools. Medical educators, particularly curricular leaders, will find opportunities in this study's results for more productive collaborations with the librarians responsible for library and informatics training at their medical schools.

Background Studies have suggested that nitrates, nitrites, and nitrosamines have an etiologic role in adverse pregnancy outcomes and chronic diseases such as cancer. Although an extensive body of literature exists on estimates of these compounds in foods, the extant data varies in quality, quantified estimates, and relevance. Methods We developed estimates of nitrates, nitrites, and nitrosamines for food items listed in the Short Willet Food Frequency Questionnaire (WFFQ) as adapted for use in the National Birth Defects Prevention Study. Multiple reference databases were searched for published literature reflecting nitrate, nitrite, and nitrosamine values in foods. Relevant published literature was reviewed; only publications reporting results for items listed on the WFFQ were selected for inclusion. The references selected were prioritized according to relevance to the U.S. population. Results Based on our estimates, vegetable products contain the highest levels of nitrate, contributing as much as 189 mg/serving. Meat and bean products contain the highest levels of nitrites with values up to 1.84 mg/serving. Alcohol, meat and dairy products contain the highest values of nitrosamines with a maximum value of 0.531 μg/serving. The estimates of dietary nitrates, nitrites, and nitrosamines generated in this study are based on the published values currently available. Conclusion To our knowledge, these are the only estimates specifically designed for use with the adapted WFFQ and generated to represent food items available to the U.S. population. The estimates provided may be useful in other research studies, specifically in those exploring the relation between exposure to these compounds in foods and adverse health outcomes. PMID:19348679

Sharing all types of clinical data and harmonizing journal standards.

PubMed

Barbui, Corrado

2016-04-03

Despite recent efforts to enforce policies requiring the sharing of data underlying clinical findings, current policies of biomedical journals remain largely heterogeneous. As this heterogeneity does not optimally serve the cause of data sharing, a first step towards better harmonization would be the requirement of a data sharing statement for all clinical studies and not simply for randomized studies. Although the publication of a data sharing statement does not imply that all data is made readily available, such a policy would swiftly implement a cultural change in the definition of scientific outputs. Currently, a scientific output only corresponds to a study report published in a medical journal, while in the near future it might consist of all materials described in the manuscript, including all relevant raw data. When such a cultural shift has been achieved, the logical conclusion would be for biomedical journals to require authors to make all data fully available without restriction as a condition for publication.

Intrusion-based reasoning and depression: cross-sectional and prospective relationships.

PubMed

Berle, David; Moulds, Michelle L

2014-01-01

Intrusion-based reasoning refers to the tendency to form interpretations about oneself or a situation based on the occurrence of a negative intrusive autobiographical memory. Intrusion-based reasoning characterises post-traumatic stress disorder, but has not yet been investigated in depression. We report two studies that aimed to investigate this. In Study 1 both high (n = 42) and low (n = 28) dysphoric participants demonstrated intrusion-based reasoning. High-dysphoric individuals engaged in self-referent intrusion-based reasoning to a greater extent than did low-dysphoric participants. In Study 2 there were no significant differences in intrusion-based reasoning between currently depressed (n = 27) and non-depressed (n = 51) participants, and intrusion-based reasoning did not predict depressive symptoms at 6-month follow-up. Interestingly, previously (n = 26) but not currently (n = 27) depressed participants engaged in intrusion-based reasoning to a greater extent than never-depressed participants (n = 25), indicating the possibility that intrusion-based reasoning may serve as a "scar" from previous episodes. The implications of these findings are discussed.

Valuing Climate Change Impacts on Human Health: Empirical Evidence from the Literature

Markandya, Anil; Chiabai, Aline

2009-01-01

There is a broad consensus that climate change will increase the costs arising from diseases such as malaria and diarrhea and, furthermore, that the largest increases will be in developing countries. One of the problems is the lack of studies measuring these costs systematically and in detail. This paper critically reviews a number of studies about the costs of planned adaptation in the health context, and compares current health expenditures with MDGs which are felt to be inadequate when considering climate change impacts. The analysis serves also as a critical investigation of the methodologies used and aims at identifying research weaknesses and gaps. PMID:19440414

Transmission electron diffraction determination of the Ge(001)-(2 × 1) surface structure

Collazo-Davila, C.; Grozea, D.; Landree, E.; Marks, L. D.

1997-04-01

The lateral displacements in the Ge(001)-(2 × 1) surface reconstruction have been determined using transmission electron diffraction (TED). The best-fit model includes displacements extending six layers into the bulk. The atomic positions found agree with X-ray studies to within a few hundredths of an ångström. With the positions determined so precisely, it is suggested that the Ge(001)-(2 × 1) surface can now serve as a standard for comparison with theoretical surface structure calculations. The results from the currently available theoretical studies on the surface are compared with the experimentally determined structure.

A longitudinal test of video game violence influences on dating and aggression: a 3-year longitudinal study of adolescents.

Ferguson, Christopher J; San Miguel, Claudia; Garza, Adolfo; Jerabeck, Jessica M

2012-02-01

In 2011 the field of video game violence experienced serious reversals with repudiations of the current research by the US Supreme Court and the Australian Government as non-compelling and fundamentally flawed. Scholars too have been calling for higher quality research on this issue. The current study seeks to answer this call by providing longitudinal data on youth aggression and dating violence as potential consequences of violent video game exposure using well-validated clinical outcome measures and controlling for other relevant predictors of youth aggression. A sample of 165, mainly Hispanic youth, were tested at 3 intervals, an initial interview, and 1-year and 3-year intervals. Results indicated that exposure to video game violence was not related to any of the negative outcomes. Depression, antisocial personality traits, exposure to family violence and peer influences were the best predictors of aggression-related outcomes. The current study supports a growing body of evidence pointing away from video game violence use as a predictor of youth aggression. Public policy efforts, including funding, would best be served by redirecting them toward other prevention programs for youth violence. Copyright © 2011 Elsevier Ltd. All rights reserved.

Monocytic cell junction proteins serve important roles in atherosclerosis via the endoglin pathway

2017-01-01

The formation of atherosclerosis is recognized to be caused by multiple factors including pathogenesis in monocytes during inflammation. The current study provided evidence that monocytic junctions were significantly altered in patients with atherosclerosis, which suggested an association between cell junctions and atherosclerosis. Claudin-1, occludin-1 and ZO-1 were significantly enhanced in atherosclerosis, indicating that the tight junction pathway was activated during the pathogenesis of atherosclerosis. In addition, the gene expression of 5 connexin members involved in the gap junction pathway were quantified, indicating that connexin 43 and 46 were significantly up-regulated in atherosclerosis. Furthermore, inflammatory factors including endoglin and SMAD were observed, suggesting that immune regulative factors were down-regulated in this pathway. Silicon-based analysis additionally identified that connexins and tight junctions were altered in association with monocytic inflammation regulations, endoglin pathway. The results imply that reduced expression of the immune regulation pathway in monocytes is correlated with the generation of gap junctions and tight junctions which serve important roles in atherosclerosis.

On the self-serving function of an academic wooden leg: test anxiety as a self-handicapping strategy.

PubMed

Smith, C W; Snyder, D R; Handelsman, M M

1982-02-01

The present study investigated the hypothesis that psychological symptoms may serve a self-protective function by providing an alternative explanation for potential failure in evaluating situations. It was hypothesized that highly test-anxious subjects would report anxiety symptoms in a pattern that reflected strategic presentation of symptoms; more specifically, it was predicted that greater reported anxiety should result when anxiety was a viable explanation for poor performance on an intelligence test and that lower reported anxiety should result when anxiety was not a viable explanation for poor performance. Analysis of state measures of self-reported anxiety supported these predictions. Further analysis indicated that when anxiety was not a viable explanation for poor test performance, high test-anxiety subjects reported reduced effort as an alternative self-protective strategy. These results are discussed in terms of traditional models of symptoms as self-protective strategies, current social psychological models of symptoms, and in reference to recent theory and research about the nature and treatment of test anxiety.

Monitoring the magnitude of marine vessel infestation by non-indigenous ascidians in the Mediterranean.

PubMed

Gewing, Mey-Tal; Shenkar, Noa

2017-08-15

Invasive ascidians (Chordata, Tunicata) are dominant nuisance organisms. The current study investigated the role of marine vessels in their dispersal and introduction. An examination of 45 dry-docked marine vessels, comprising recreational, commercial, and military craft, in five Israeli shipyards along the Mediterranean coast, revealed non-indigenous ascidians (NIA) on every second vessel investigated. Military vessels featured the highest ascidian abundance and richness, potentially related to their maintenance routine. Niche areas on the vessels such as sea chests and the propeller exhibited the highest occurrence of ascidians. Overall, these findings provide strong evidence that marine vessels play an acute role in NIA introduction and dispersal, with military vessels and niche areas on all the vessels being more susceptible to serving as vectors. A discovery of a new introduced species during the surveys suggests that the monitoring of marine vessels can serve as an effective tool for the early detection of NIA. Copyright © 2017 Elsevier Ltd.

Public Sector Employment Inequality in the United States and the Great Recession.

PubMed

Laird, Jennifer

2017-02-01

Historically in the United States, the public sector has served as an equalizing institution through the expansion of job opportunities for minority workers. This study examines whether the public sector continues to serve as an equalizing institution in the aftermath of the Great Recession. Using data from the Current Population Survey, I investigate changes in public sector employment between 2003 and 2013. My results point to a post-recession double disadvantage for black public sector workers: they are concentrated in a shrinking sector of the economy, and they are more likely than white and Hispanic public sector workers to experience job loss. These two trends are a historical break for the public sector labor market. I find that race and ethnicity gaps in public sector employment cannot be explained by differences in education, occupation, or any of the other measurable factors that are typically associated with employment. Among unemployed workers who most recently worked for the public sector, black women are the least likely to transition into private sector employment.

Rapid life time change of the Malaysian lifestyle had served the overwhelming growth in the service operation industry. On that occasion, this paper will provide the idea to improve the waiting line system (WLS) practices in Malaysia fast food chains. The study will compare the results in between the single server single phase (SSSP) and the single server multi-phase (SSMP) which providing Markovian Queuing (MQ) to be used for analysis. The new system will improve the current WLS, plus intensifying the organization performance. This new WLS were designed and tested in a real case scenario and in order to develop and implemented the new styles, it need to be focusing on the average number of customers (ANC), average number of customer spending time waiting in line (ACS), and the average time customers spend in waiting and being served (ABS). We introduced new WLS design and there will be prompt discussion upon theories of benefits and potential issues that will benefit other researchers.

Most young children are in child care. Previous studies suggest that children may receive insufficient vegetables, and foods and beverages with added sugars, fats, and sodium in these settings. None have compared the nutritional quality of meals to snacks. Directors from 258 full-day child-care centers in two urban counties of southwestern Ohio were surveyed via telephone in the fall of 2009 about their nutrition practices, and asked to provide a current menu. Lunch and afternoon snack menus were categorized according to average weekly frequency for fruits, vegetables, lean meats, juice (100%), and sweet or salty foods served. Frequencies were compared by meal occasion (lunch vs. snack) using the Fisher exact test. Most (60%) directors reported serving 2% milk to children ≥3 years; 31% served whole milk. Menu analysis demonstrated the composition of lunches differed from snacks (p<0.0001) in all food categories. A total of 87% centers rarely (<1 time per week) listed nonstarchy vegetables for snacks, but 67% of centers included them at lunch ≥3 times per week. Juice (100%) was on snack menus >2 times per week in 37% centers, but in only 1 center as a regular component of lunch. Similarly, 87% centers listed sweet and salty foods at snack ≥3 times per week, but rarely at lunch. Despite efforts to improve children's diets in child care, meals-and particularly snacks-still lack whole fruits and nonstarchy vegetables and contain added sugars and fats. Snacks represent a missed opportunity to improve the nutritional quality of foods served in childcare.

The aim of this study was to analyze the technical-tactical performance profile of the serve for various age groups and categories of competition in men's volleyball. The sample comprised 13,262 serves performed by 986 players in 299 sets observed in various categories of competition (U-14, U-16, U-19, national senior, and international senior). An observational design was used. The variables studied were category of competition, type of execution, and serve performance. The results showed that for higher age groups (senior categories), there were significantly fewer jump serves and poorer serve performance, regardless of players' maturity and training development. The use of the jump serves increased the serve risk while attempting to hinder the organization of the opponent attack. This paper discusses the serve evolution and the implications on the training process at the different age groups in men's volleyball. © The Author(s) 2016.

The 300 mA SRF ERL

Ben-Zvi, Ilan

Energy Recovery Linacs (ERL) are important for a variety of applications, from high-power Free-Electron Lasers (FEL) to polarized-electron polarized-proton colliders. The ERL current is arguably the most important characteristic of ERLs for such applications. With that in mind, the Collider-Accelerator Department at Brookhaven National Laboratory embarked on the development of a 300 mA ERL to serve as an R and D test-bed for high-current ERL technologies. These include high-current, extremely well damped superconducting accelerating cavities, high-current superconducting laser-photocathode electron guns and high quantum-efficiency photocathodes. In this presentation I will cover these ERL related developments.

A new high-current electron gun with plasma anode and explosive-emission cathode integrated with planar pulsed powered magnetron is described. Five hundred twelve copper wires 1 mm in diameter and 15 mm in height serve as emitters. These emitters are installed on stainless steel disc (substrate) with 3-mm distance between them. Magnetron discharge plasma provides increased ion density on the periphery of plasma anode formed by high-current Penning discharge ignited within several milliseconds after starting of the magnetron discharge. The increased on the periphery ion density improves the uniformity of high-current electron beam produced in such an electron gun.

Legal liability is an increasing concern in many areas of medicine, although the extent to which this alters the practice of medicine is unclear. To date the risk for litigation against medical toxicologists serving in the role of poison control center (PCC) consultants has not been assessed. A survey questionnaire was mailed to medical toxicologists in the United States to assess their litigation history with regard specifically to their role as PCC consultants. In addition, state laws were examined for statutes that provide protective language with regard to medical toxicologists working as PCC consults. This survey revealed that most medical toxicologists have served or currently serve as PCC consultants. Most had some degree of concern over legal liability, and several had been sued as a result of PCC consultations. Several states have specific statutes that limit the legal liability of PCCs and their employees, including medical directors and consulting medical toxicologists. Based on the survey results, legal action against toxicologists serving as PCC consultants appears to be an uncommon occurrence. Lawsuits are usually based upon nonfeasance and have typically been settled or dropped before trial. Legal liability is a concern for PCC consultants. However, legal action against consultants appears to be rare, and respondents to the survey indicated that it did not affect their advice or willingness to serve as PC consultants. A limited number of states have enacted laws that provide protection for medical toxicologists serving as PCC consultants.

Observation of hole hopping via dopant in MoOx-doped organic semiconductors: Mechanism analysis and application for high performance organic light-emitting devices

Conduction mechanism in molybdenum trioxide (MoOx)-doped hole- and electron-type organic semiconductors is investigated. The used hole-transporting materials are N ,N'-diphenyl-N ,N'-bis(1-naphthylphenyl)-1, 1'-biphen4, 4'-diamine, 4',4″-tri(N-carbazolyl)triphenylamine, 4, 4'-N,N-dicarbazole-biphenyl, and pentacene and the used electron-transporting material is (8-quinolinolato) aluminum (Alq3). It can be seen that the hole conductivity is significantly enhanced upon MoOx doping, and more importantly, dominant hole current could be realized in a typical electron-transport material Alq3 by doping MoOx. Hence, high efficiency organic light-emitting devices can also be achieved even using MoOx-doped Alq3 film as hole transporting layer. The mechanism investigation indicates that the MoOx plays an important role in the hole transport. It is showed that the MoOx serves as the hole hopping sites, whereas the used organic materials serve as the transport medium and determine the magnitude of transport current. Furthermore, it is found that doping MoOx into the organic materials also reduces the energy and position disorders of the doped organic films, which are well demonstrated by the study on transport characteristics of the doped films at various temperatures.

On call at the mall: a mixed methods study of U.S. medical malls

PubMed Central

2013-01-01

Background The decline of the traditional U.S. shopping mall and a focus on more consumer- centered care have created an opportunity for “medical malls”. Medical malls are defined as former retail spaces repurposed for healthcare tenants or mixed-use medical/retail facilities. We aimed to describe the current reach of healthcare services in U.S. malls, characterize the medical mall model and emerging trends, and assess the potential of these facilities to serve low-income populations. Methods We used a mixed methods approach which included a comprehensive literature review, key informant interviews, and a descriptive analysis of the Directory of Major Malls, an online retail database. Results Six percent (n = 89) of large, enclosed shopping malls in the U.S. include at least one non-optometry or dental healthcare tenant. We identified a total of 28 medical malls across the U.S., the majority of which opened in the past five years and serve middle or high income populations. Stakeholders felt the key strengths of medical malls were more convenient access including public transportation, greater familiarity for patients, and “one stop shopping” for primary care and specialty services as well as retail needs. Conclusions While medical malls currently account for a small fraction of malls in the US, they are a new model for healthcare with significant potential for growth. PMID:24209495

The northern Gulf of Mexico is strongly influenced by the discharge of water, nutrients, dissolved and suspended particulate matter from the Mississippi-Atchafalaya River system, the largest in North America. It is also frequently impacted by energetic meteorological events that cause storm surge, high waves and affects water quality along its coastal waters. We describe the components of an integrated web-based Gulf Coast Information System (GCIS) (http://gulf-coast.lsu.edu) developed to serve remotely sensed products from a number of NASA satellite sensors such as the SeaWiFS and MODIS ocean color and the QuikSCAT wind sensors. GCIS also serves high-resolution nowcast and 48-hour forecast outputs (sea level variations, temperature, salinity and currents) from a 3-dimensional NCOM coastal circulation model for the coastal states of Mississippi, Louisiana and Texas. The GCIS is coupled to the near real-time outputs of a field monitoring and satellite receiving system, the Wave-Current Information System (WAVCIS) (http://www.wavcis.lsu.edu) and Earth Scan Laboratory (ESL) (www.esl.lsu.edu), respectively that provide critical decision support during hurricanes to the Gulf Coast. We present results on the use of the combined field, satellite and model outputs to monitor the effects of fronts, hurricanes, oil spill and the potential to study longer term climate impacts along the Gulf coast.

Heat shock protein 90 (HSP90) serves as a critical facilitator for oncogene addiction. There has been augmenting enthusiasm in pursuing HSP90 as an anticancer strategy. In fact, since the initial serendipitous discovery that geldanamycin (GM) inhibits HSP90, the field has rapidly moved from proof-of-concept clinical studies with GM derivatives to novel second-generation inhibitors. The authors highlight the current status of the second-generation HSP90 inhibitors in clinical development. Herein, the authors note the lessons learned from the completed clinical trials of first- and second-generation inhibitors and describe various assays attempting to serve for a more rational implementation of these agents to cancer treatment. Finally, the authors discuss the future perspectives for this promising class of agents. The knowledge gained thus far provides perhaps only a glimpse at the potential of HSP90 for which there is still much work to be done. Lessons from the clinical trials suggest that HSP90 therapy would advance at a faster pace if patient selection and tumor pharmacokinetics of these drugs were better understood and applied to their clinical development. It is also evident that combining HSP90 inhibitors with other potent anticancer therapies holds great promise not only due to synergistic antitumor activity but also due to the potential of prolonging or preventing the development of drug resistance.

Toanalyse the prevalence of distress in doctors serving in a tertiary care hospital and studying the factors having significant impact on the subject. The cross-sectional study was conducted at the Combined Military Hospital, Lahore, from February to December 2014, and comprised doctors serving for at least six months who volunteered to fill out the standardised General Health Questionnaire-12Demographic features and level of job satisfaction were taken as independent variables. Outcome variable was the questionnaire score. SPSS 20 was used for data analysis. The mean questionnaire score of the 97 respondents in the study was 12.27±6.397. Of them, 19(19.6%) and 11(11.3%) had distress and severe distress respectively. Marital status (p=0.006), age (p=0.029), income per month (p=0.010) and levels of job satisfaction (p=0.001) had significant impact on the scores. Variables having insignificant impact were gender (p=0.529), number of children (p=0.220), education (p=0.816), service years (p=0.155), current employment (p=0.504), nature of job (p=0.531), working hours (p=0.632), additional duties (p=0.663), and socioeconomic class (p=0.935). Almost one-third of the doctors had distress under the significant impact of multiple factors.
