Herein, we have evaluated relative changes in M-S electronic structure and orbital mixing in Group 6 MS4(2-) dianions using solid- and solution-phase S K-edge X-ray absorption spectroscopy (XAS; M = Mo, W), as well as density functional theory (DFT; M = Cr, Mo, W) and time-dependent density functional theory (TDDFT) calculations. To facilitate comparison with solution measurements (conducted in acetonitrile), theoretical models included gas-phase calculations as well as those that incorporated an acetonitrile dielectric, the latter of which provided better agreement with experiment. Two pre-edge features arising from S 1s → e* and t electron excitations were observed in the S K-edge XAS spectra and were reasonably assigned as (1)A1 → (1)T2 transitions. For MoS4(2-), both solution-phase pre-edge peak intensities were consistent with results from the solid-state spectra. For WS4(2-), solution- and solid-state pre-edge peak intensities for transitions involving e* were equivalent, while transitions involving the t orbitals were less intense in solution. Experimental and computational results have been presented in comparison to recent analyses of MO4(2-) dianions, which allowed M-S and M-O orbital mixing to be evaluated as the principle quantum number (n) for the metal valence d orbitals increased (3d, 4d, 5d). Overall, the M-E (E = O, S) analyses revealed distinct trends in orbital mixing. For example, as the Group 6 triad was descended, e* (π*) orbital mixing remained constant in the M-S bonds, but increased appreciably for M-O interactions. For the t orbitals (σ* + π*), mixing decreased slightly for M-S bonding and increased only slightly for the M-O interactions. These results suggested that the metal and ligand valence orbital energies and radial extensions delicately influenced the orbital compositions for isoelectronic ME4(2-) (E = O, S) dianions.

Full Text Available Background: Both substance use and anxiety-depression spectrum are the problem that currently faced by adolescents especially among Senior High School students. Moreover, there is a high comorbidity between both problems. This study was conducted to discover the substance use’s prevalence and to find out anxiety-depression spectrum proportion among adolescent, and more importantly to determine whether there is correlation between both variables. Methods: During October–November 2013, four hundred and fifty two students from five Senior High Schools located in Karees Sub-District, Bandung were included in this cross-sectional analytic study. Among whom, only 425 students filled the questionnaire properly. Data were collected using Kessler-10 (K10 to explore anxiety-depression spectrum and addiction severity index lite version (ASI-Lite to identify substance use. The correlation between both variables was analyzed by Gamma correlation test. Results: The study revealed that there were 93 (21.9% students that used substance. In addition, there were 244 students (57.4% that screened as having anxiety-depression spectrum. Statistical analysis, according to Gamma correlation test, showed that there was a weak correlation between alcohol use and anxiety-depression spectrum (p=0.041; r=0.316. The remaining substances gave no statistically significant result (p>0.05. Conclusions: There is a high prevalence in substance use and psychological distress in anxiety-depression spectrum among high school student. In addition, alcohol is the only substances that correlated with anxiety-depression spectrum.

In 2000, the Senior Mentor Program was implemented as an innovative, instructional method in the University of South Carolina's medical school curriculum designed to enhance and strengthen student training in geriatrics. This study qualitatively analyzed second- year medical students' and senior participants' perceptions of and attitudes towards the Senior Mentor Program as an effective learning modality. A total of 36 second-year students from two consecutive classes (2002-2003) and 42 senior mentors at USC's School of Medicine participated in five and seven separate focus group interviews, respectively. The group discussions were transcribed and a content analysis performed using NVivo. The coding scheme and analyses were driven by the data collected and recurrent themes were examined across all focus groups. Overall, student and senior mentor participants viewed the program positively. Thematic comparisons by participant type indicate a shared view that the mentoring relationship has a far-reaching, educational, professional, and personal impact. Both students and seniors agreed that myths and stereotypes about aging were dispelled and students indicated that a close, caring relationship with an older person will change they way they practice. A longitudinal mentoring program that pairs students with community-dwelling seniors can be a valuable addition to traditional geriatric curricular activities designed to increase students' skills and compassion for caring for older adults.

2018-04-01

Role ambiguity is a lack of clarity or uncertainty related to one's position or role. Role ambiguity has been documented in the literature in relationship to athletics, industry, business, education, and nursing. However, a concept analysis has not been performed. Therefore, the process of concept analysis outlined by Walker and Avant is now used to look at the concept of role ambiguity and its relevance to senior nursing students' socialization and education into the profession of nursing. Attributes, antecedents, consequences, and empiric referents are discussed and theories commonly associated with role ambiguity are presented. At the end of the analysis, an operational definition is provided for use in exploring the concept of role ambiguity as it relates to senior nursing students' articulation of the role of the professional nurse. © 2017 Wiley Periodicals, Inc.

This study examines how the changes in weight status across the spectrum of a senior high school study are associated with academic performance measured by the university entrance exam scores. A unique dataset which compiles a national health examination profile and the General Scholastic Ability Test data bank in Taiwan was constructed. The final sample comprised 149,240 senior high school students of which 70,662 were males and 78,578 were female students. The school-level fixed effect models were estimated. Students who were either (a) not overweight in the first year but overweight in the third year of senior high school, (b) overweight in both the first and third year, or (c) overweight in the first year but not overweight in the third year, were more likely to score lower on the university entrance exam, compared with their never-overweight counterparts. The findings differ by gender and test subjects. The change in weight status during senior high school period is associated with subsequent university entrance exam outcome. Students who start senior high school being overweight should be paid attention. School-based programs and practices need to be implemented to reduce the prevalence of overweight among students.

The application and interview behaviors of unmatched U.S. allopathic medical school senior students (U.S. seniors) participating in the 2015 National Resident Matching Program (NRMP) Main Residency Match were studied in conjunction with their United States Medical Licensing Examination (USMLE) Step 1 scores and ranking preferences to understand their effects on Match outcome. USMLE Step 1 score and preferred specialty information were reviewed for U.S. seniors who responded to the 2015 NRMP Applicant Survey. Unmatched U.S. seniors were categorized as "strong," "solid," "marginal," or "weak" based on the perceived competitiveness of their Step 1 scores compared with U.S. seniors who matched in the same preferred specialty. The numbers of applications sent, interviews obtained, and programs ranked also were examined by Match outcome. Strong unmatched U.S. seniors submitted significantly more applications to achieve and attend approximately the same number of interviews as strong matched U.S. seniors. Strong unmatched seniors ranked fewer programs than their matched counterparts. As a group, unmatched U.S. seniors were less likely than their matched counterparts to rank a mix of competitive and less competitive programs and more likely to rank programs based on their perceived likelihood of matching. A small number of unmatched U.S. seniors would have matched if they had ranked programs that ranked them. U.S. seniors' Match outcomes may be affected by applicant characteristics that negatively influence their selection for interviews, and their difficulties may be exacerbated by disadvantageous ranking behaviors.

2015-03-01

Senior nursing students are faced with various types of stressful events such as taking the national licensure exam or finding employment. Such stress can generate maladaptive behaviors as well as physical and psychological symptoms. There is evidence supporting the use of rational emotive behavior therapy (REBT) for reducing disruptive behaviors and negative emotions as well as improving self-efficacy and stress-coping strategies. The purpose of this study is to examine the effects of rational emotive behavior therapy (REBT) on stress coping strategies and self-efficacy for senior nursing students. Thirty-four senior nursing students in a nursing college were assigned randomly to an experimental group (n=18) and a control group (n=16). The REBT program consisted of 8 sessions, and it was implemented for a 4-week period. Outcome measures assessed stress-coping strategies and self-efficacy before and after intervention. After intervention with REBT, the mean difference scores for self-efficacy (p=.032) were significantly higher in the experimental group than in the control group. However, the mean difference scores for seeking social support (p=.166), problem solving (p=.126), and avoidance (p=.154) in stress-coping strategies were not significantly different between the two groups. The results imply that group counseling based on REBT enhances the self-efficacy among senior nursing students before graduation. As regards stress coping strategies, a longer intervention period is suggested. Copyright © 2014 Elsevier Ltd. All rights reserved.

The aim of this study was to identify the significance of spirituality in enhancing self-efficacy related to professional values in senior nursing students. Self-efficacy can predict job satisfaction and performance as professional nurses in clinical settings. Senior nursing students should have the level of self-efficacy that enables them to perform professional roles based on professional values, because they will enter clinical settings immediately after graduation. Spirituality may help senior nursing students during the transition to professional life to reflect on their skills, knowledge and situations to enhance self-efficacy based on professional values. An exploratory, cross-sectional design was used in this study. A total of 194 senior nursing students in South Korea were recruited in 2014. They completed self-reported questionnaires consisting of demographic questions, Spiritual Assessment Scale, Self-Efficacy Scale and Nursing Professional Values inventory. A Sobel test was done to determine the mediating effect of spirituality on the relationship between nursing professional values and self-efficacy. The findings showed a positive correlation between professional values, spirituality and self-efficacy in nursing students. According to the Sobel test, spirituality had a mediating effect on the relationship between professional values and self-efficacy in senior nursing students. Spirituality can be a foundation that provides senior nursing students with higher self-efficacy so that they are able to perform their professional roles based on their professional values. The findings can guide nursing educators to include spiritual development of nursing students to enhance the self-efficacy of senior nursing students, the future of the nursing profession. © 2016 John Wiley & Sons Ltd.

Research suggests stereotyping by clinicians as one contributor to racial and gender-based health disparities. It is necessary to understand the origins of such biases before interventions can be developed to eliminate them. As a first step toward this understanding, we tested for the presence of bias in senior medical students. The purpose of the study was to determine whether bias based on race, gender, or socioeconomic status influenced clinical decision-making among medical students. We surveyed seniors at 84 medical schools, who were required to choose between two clinically equivalent management options for a set of cardiac patient vignettes. We examined variations in student recommendations based on patient race, gender, and socioeconomic status. The study included senior medical students. We investigated the percentage of students selecting cardiac procedural options for vignette patients, analyzed by patient race, gender, and socioeconomic status. Among 4,603 returned surveys, we found no evidence in the overall sample supporting racial or gender bias in student clinical decision-making. Students were slightly more likely to recommend cardiac procedural options for black (43.9 %) vs. white (42 %, p = .03) patients; there was no difference by patient gender. Patient socioeconomic status was the strongest predictor of student recommendations, with patients described as having the highest socioeconomic status most likely to receive procedural care recommendations (50.3 % vs. 43.2 % for those in the lowest socioeconomic status group, p socioeconomic status, geographic variations, and the influence of interactions between patient race and gender on student recommendations.

Full Text Available While it is important for college and university senior administrators to embrace the traditional roles of their administrative positions, senior administrators’ interactions with students also shape institutional culture, students’ engagement, and ultimately play a role in students’ motivation to succeed. This engagement is especially evident in the Historically Black College and University (HBCU context as senior administrators’ engagement with students can directly or indirectly affect how students perceive themselves and their ability to succeed. This article aims to illuminate the role that HBCU senior level administrators play in students’ motivation toward success. We also highlight the notion that senior level administrators’ role in organizational culture ultimately led historically-disempowered Black women students toward success in even the most historically inaccessible pathways in the science, technology, engineering, and math (STEM fields. The study used semi-structured interviews with 71 Black women STEM students across 10 HBCUs and asked questions to better understand how events in their lives and on their campuses shaped their choice to pursue and persist through a STEM degree program. The study found that the women were highly motivated by their HBCUs’ family-like community of support. Integral to this article, this support was not confined to professors and peers, but extended to senior administrators. We conclude that Black women STEM students’ perception of their ability to succeed and their motivation is influenced by the institutions’ senior administration.

OBJECTIVES: To compare the views of freshman students with senior students of the Faculty of Medicine- University of São Paulo concerning the respect for the mother’s freedom of choice, the need to protect the unborn child, the proportionality between the mother’s freedom of choice and the protection of the unborn child, and issues related to legal abortion. To determine whether the medical knowledge acquired throughout the academic years can influence the views of medical students on these issues. METHODS: First- and sixth-year students of the Faculty of Medicine – University of São Paulo answered a questionnaire; the inclusion criteria were as follows: a first- or sixth-year student of the medical school and a signature on the free informed consent form. To compare the proportions, a chi-square or Fisher’s exact test was used. The significance level was set to 5%. RESULTS: Regarding the mother’s freedom of choice, in the case when a pregnant woman undergoes a cesarean section by means of a court order despite her intention to not have a cesarean, 55.7% of the first-year students have answered that the mother’s choice should be respected. Among the sixth-year students, only 28.9% believe that the mother’s intention should be considered (p<0.0001). With reference to the mother’s choice in connection with antiretroviral medication, 38.1% of the first-year students agreed that the mother’s intention should be respected, whereas 33% of sixth-year students believed that the mother’s intention should be respected (p=0.453). CONCLUSION: There was a tendency to consider the unborn child’s rights over the mother’s choice as students spent more time in medical school. PMID:27759844

Wanchek, Tanya; Cook, Bryan J; Valachovic, Richard W

2017-05-01

This report examines the results of the American Dental Education Association (ADEA) Survey of Dental School Seniors graduating in 2016. Data were collected from 4,558 respondents at all 59 U.S. dental schools with graduating classes that year. This annual survey asks graduating students about a variety of topics in order to understand their motivation for attending dental school, educational experiences while in school, debt incurred, and plans following graduation. Motivations for choosing to attend dental school typically involved family or friends who were dentists or students' personal experiences. The timing of the decision to enter dentistry has been getting earlier over time. Similar to previous years, the average graduating student had above $200,000 in student debt. However, for the first time in two decades, inflation-adjusted debt decreased slightly. The reduction in debt was due to students from private schools reducing their average debt by $23,401. Immediately after graduation, most seniors planned to enter private practice (50.5%) or advanced dental education (33.8%). Approximately half of the respondents planned to work in underserved areas at some point in their careers. These findings underscore the continued value of the senior survey to offer a unique view of the diverse characteristics and career paths of the future dental workforce.

Full Text Available Most policymakers and academics agree that entrepreneurship is critical to the development and well-being of society. Entrepreneurs create jobs. They drive and shape innovation, speeding up structural changes in the economy. By introducing new competition, they contribute indirectly to productivity. Entrepreneurship is thus a catalyst for economic growth and national competitiveness. While there has been significant research on the causes of entrepreneurial propensity, only a limited number of studies have focused on the entrepreneurial intent among students (especially Senior High School students. Currently, in Ghana graduate unemployment has become an albatross around the necks of the average school leaver in particular and the society in general. Graduate unemployment has increased the already high dependency syndrome and many believe entrepreneurship is the number one medicine to this unfortunate situation. 42-item questions were used to assess the entrepreneurial intention. Two mixed and two single-sex institutions in the Sunyani municipality were studied. The sample size for the study was 499 for the four (4 institutions. Data was analyzed via SPSS-17.0. The study seeks: to identify the impact of family business on entrepreneurial intention; to assess the students’ perception on the impact of education on entrepreneurial intention; to identify the risk-taking propensity of senior high school (SHS students in the Sunyani Municipality; to compare males’ entrepreneurial intentions with females; to examine SHS students’ orientation towards entrepreneurship. It is believed that the ideal stage to acquire basic knowledge about entrepreneurship and to foster a positive attitude towards entrepreneurship is during childhood and adolescence years. Generally, entrepreneurial intention among SHS students in the Sunyani municipality is high according to this study.

Critical thinking is an important and necessary skill to confront the challenges of the 21st century. Critical thinking skills accommodate activities that can improve high-order thinking skills. This study aims to determine senior high school students' critical thinking skills in Biology learning. This research is descriptive research using instruments developed based on the core aspects of critical thinking skills according to Facione which include interpretation, analysis, evaluation, explanation, conclusion, and self-regulation. The subjects in this study were 297 students in grade 12 of a senior high school in Surakarta selected through purposive sampling technique. The results of this study showed that the students' critical thinking skills on evaluation and self-regulation are in good criterion with 78% and 66% acquisition while 52% interpretation, 56% analysis, 52% conclusion and 42% explanation indicate sufficient criteria. The conclusion from this research is that critical thinking skill of the students still was in enough category, so that needed a way to enhance it on some indicators.

This study compared the movement demands of elite international Under-20 age grade (U20s) and senior international rugby union players during competitive tournament match play. Forty elite professional players from an U20 and 27 elite professional senior players from international performance squads were monitored using 10Hz global positioning systems (GPS) during 15 (U20s) and 8 (senior) international tournament matches during the 2014 and 2015 seasons. Data on distances, velocities, accelerations, decelerations, high metabolic load (HML) distance and efforts, and number of sprints were derived. Data files from players who played over 60 min (n = 258) were separated firstly into Forwards and Backs, and more specifically into six positional groups; FR–Front Row (prop & hooker), SR–Second Row, BR–Back Row (Flankers & No.8), HB–Half Backs (scrum half & outside half), MF–Midfield (centres), B3 –Back Three (wings & full back) for match analysis. Linear mixed models revealed significant differences between U20 and senior teams in both the forwards and backs. In the forwards the seniors covered greater HML distance (736.4 ± 280.3 vs 701.3 ± 198.7m, p = 0.01) and severe decelerations (2.38 ± 2.2 vs 2.28 ± 1.65, p = 0.05) compared to the U20s, but performed less relative HSR (3.1 ± 1.6 vs 3.2 ± 1.5, p rugby, however, the current study highlight for the first time that certain positional groups may require more time to be able to match the movement demands required at a higher playing level than others. Conditioning staff must also bear in mind that the U20s players whilst maintaining or improving match movement capabilities may require to gain substantial mass in some positions to match their senior counterparts.

It is widely accepted that students in Japan sleep fewer hours than what they actually need. However, epidemiological data on sleep habits among students are scarce. The sleep habits and related problems among 1650 students in Akita prefecture were studied. The results revealed that schoolchildren attending elementary schools seemed to sleep for a sufficient number of hours, whereas students attending junior or senior high schools were not sleeping enough. In particular, approximately half of the students attending senior high schools answered that they slept 6 h or less on weekdays and nodded off during classes more than twice a week.

Leadership skills are essential for a successful career as a physician-scientist, yet many MD–PhD training programs do not offer formal training in leadership. The Vanderbilt Medical Scientist Training Program (MSTP) previously established a 2-day leadership workshop that has been held biennially since 2006 for students in the first and second years of the graduate school portion of combined MD and PhD training (G1/G2 students). Workshop attendees have consistently rated this workshop as a highly effective experience. However, opportunities for structured training in leadership competencies during the subsequent 3–5 years of MD–PhD training are limited. Given the success of the G1/G2 leadership workshop and the need for continuity in this model of leadership training, we developed a half-day workshop for MSTP students in the clinical years of medical school (M3/M4 students) to foster continued training in leadership. Our workshop curriculum, based in part on original cases drafted by Vanderbilt MSTP students, provides concrete strategies to manage conflict and navigate leadership transitions in the physician-scientist career path. The curriculum emphasizes both short-term competencies, such as effective participation as a member of a clinical team, and long-term competencies, such as leadership of a research team, division, or department. Our inaugural senior leadership workshop, held in August, 2015, was judged by student participants to be well organized and highly relevant to leadership concepts and skills. It will be offered biennially in our training curriculum for M3 and M4 MSTP students. PMID:27499363

Gottlieb, Zoe; Epstein, Samantha; Richards, Jeremy

2017-06-01

Near-peer teaching (NPT) is increasingly recognised as an effective method for teaching and learning within medical education. We describe a student-as-teacher programme developed for fourth-year students (MS4s) helping to deliver the second-year Respiratory Pathophysiology course at our medical school. Twelve MS4s were paired with faculty members to co-teach one or two small group case-based sessions for second-year students (MS2s). Beforehand, MS4s attended an orientation session and workshop, reviewing skills and strategies for teaching effectively. Following each teaching session co-taught by MS4s, both MS4s and MS2s completed multiple-choice surveys evaluating the MS4's teaching skills and the experience overall. MS4s also wrote reflection essays describing their experiences. Faculty member co-teachers completed a 12-question feedback form for MS4s during the session. We received 114 post-session MS2 surveys, 13 post-session MS4 surveys and 13 post-session faculty staff evaluations. The majority of MS2s reported that MS4s enhanced their understanding of the material, and considered the quality of MS4 teaching to be 'good' or 'outstanding'. Nearly all of the MS4s enjoyed their experiences and believed that the programme improved their teaching skills. Time management was the most common challenge cited by both MS4s and faculty member co-teachers. These data demonstrate that NPT is valuable for both MS2s and MS4s: MS2s benefited from the social and cognitive congruence afforded by near-peer teachers, whereas MS4s used this experience to build and enhance their skills as educators. These results support the continued involvement of MS4s in this second-year course, as well as broadening the scope of and opportunities for student teaching at our medical school and beyond. Near-peer teaching is recognised as an effective method for teaching and learning within medical education. © 2016 John Wiley & Sons Ltd and The Association for the Study of Medical Education.

To gather information from senior dental students about their future career plans, with particular emphasis on work-life balance issues, their attitudes towards the NHS and retirement plans. Senior dental students at the Universities of Dundee and Manchester were asked to complete a voluntary anonymous questionnaire. In all 141 questionnaires were completed, 42 by students in Manchester and 114 in Dundee. On qualification nearly all surveyed intend to work full time but after five years one quarter (26%) of females intend to work part time. This is significantly (p work full time. Although the majority (65%) intend to work in general practice significant numbers (19%) wish to have a career in hospital dentistry and very few (3%) in community dentistry. Senior students seem to show no more commitment to the NHS than those in our previous study of dental school applicants. Only 3% intend to work exclusively for the NHS and 18% intend to work exclusively in the private sector. Surprising numbers had plans to retire or go part time before 60 years of age. Only 20% of the sample intended to continue working full time after the age of 60 years. The mode age that those surveyed intended to start a family was 30 years and a large majority of both sexes thought this would interrupt their professional life. More than half of the sample intend to take time out of dentistry until their children attended primary school (female 63%, male 38%) and 6% (female 6%, male 8%) until secondary school. Many of our findings suggest that future generations of dentists may have a pattern of professional life that will have the effect of reducing their clinical commitment, although it is not possible to determine how significant an effect this will have on the workforce. It may, however, be appropriate to take career intention into account when workforce planning.

Medical schools throughout the country struggle with how best to train students to provide quality, patient-centered care to the burgeoning population of older adults. The Senior Sages Program (SSP) is a longitudinal Senior Mentor Program (SMP) that offers students the opportunity to learn about the aging process and core geriatric medicine concepts through the eyes of an aging expert: their Senior Sage. The SSP marries a robust electronic curriculum with an SMP and online discussion board. The aim of this program evaluation was to measure the impact on students' geriatric knowledge and attitudes toward older adults. This asynchronously facilitated course improved students' geriatric knowledge and facilitated stability of positive attitudes toward older adults. The majority of students felt that their SSP interactions were meaningful and valuable to their clinical development. The combination of SMP and electronic curricula offer a feasible, practical way to bridge the geriatric training chasm.

Alzheimer's disease susceptibility variants in the MS4A6A gene are associated with altered levels of MS4A6A expression in blood.

2014-02-01

An increased risk of developing Alzheimer's disease (AD) has previously been found to be associated with variants at the MS4A6A locus. We sought to identify which genes and transcripts in this region have altered expression in AD and mild cognitive impairment (MCI) and are influenced by the AD risk variant(s), as a first step to understanding the molecular basis of AD susceptibility at this locus. Common variants located within highly expressed MS4A6A transcripts were significantly associated with AD and MS4A6A expression levels in blood from MCI and AD subjects (p < 0.05, rs610932, rs7232, rs583791). More copies of the protective (minor) allele were associated with lower MS4A6A expression of each transcript (e.g., p = 0.019; rs610932-total MS4A6A). Furthermore, in heterozygous AD subjects, relative expression of the protective allele of V4-MS4A6A transcripts was lower (p < 0.008). Irrespective of genotype, MS4A6A transcripts were increased in blood from people with AD (p < 0.003), whereas lower expression of full length V1-MS4A6A (p = 0.002) and higher expression of V4-MS4A6A (p = 1.8 × 10(-4)) were observed in MCI, relative to elderly controls. The association between genotype and expression was less consistent in brain, although BA9 did have a similar genotype association with V4-MS4A6A transcripts as in blood. MS4A6A transcripts were widely expressed in tissues and cells, with the exception of V4-MS4A6A, which was not expressed in neuronal cells. Together these results suggest that high levels of MS4A6A in emerging AD pathology are detrimental. Persons with MCI may lower MS4A6A expression to minimize detrimental disease associated MS4A6A activity. However, those with the susceptibility allele appear unable to decrease expression sufficiently, which may explain their increased risk for developing AD. Inhibiting MS4A6A may therefore promote a more neuroprotective phenotype, although further work is needed to establish whether this is the case. Copyright © 2014

Phylogenetic analysis of the MS4A and TMEM176 gene families.

Directory of Open Access Journals (Sweden)

Jonathan Zuccolo

2010-02-01

Full Text Available The MS4A gene family in humans includes CD20 (MS4A1, FcRbeta (MS4A2, Htm4 (MS4A3, and at least 13 other syntenic genes encoding membrane proteins, most having characteristic tetraspanning topology. Expression of MS4A genes is variable in tissues throughout the body; however, several are limited to cells in the hematopoietic system where they have known roles in immune cell functions. Genes in the small TMEM176 group share significant sequence similarity with MS4A genes and there is evidence of immune function of at least one of the encoded proteins. In this study, we examined the evolutionary history of the MS4A/TMEM176 families as well as tissue expression of the phylogenetically earliest members, in order to investigate their possible origins in immune cells.Orthologs of human MS4A genes were found only in mammals; however, MS4A gene homologs were found in most jawed vertebrates. TMEM176 genes were found only in mammals and bony fish. Several unusual MS4A genes having 2 or more tandem MS4A sequences were identified in the chicken (Gallus gallus and early mammals (opossum, Monodelphis domestica and platypus, Ornithorhyncus anatinus. A large number of highly conserved MS4A and TMEM176 genes was found in zebrafish (Danio rerio. The most primitive organism identified to have MS4A genes was spiny dogfish (Squalus acanthus. Tissue expression of MS4A genes in S. acanthias and D. rerio showed no evidence of expression restricted to the hematopoietic system.Our findings suggest that MS4A genes first appeared in cartilaginous fish with expression outside of the immune system, and have since diversified in many species into their modern forms with expression and function in both immune and nonimmune cells.

Experiential learning model using simple physics kit has been implemented to get a picture of improving attitude toward physics senior high school students on Fluid. This study aims to obtain a description of the increase attitudes toward physics senior high school students. The research method used was quasi experiment with non-equivalent pretest -posttest control group design. Two class of tenth grade were involved in this research 28, 26 students respectively experiment class and control class. Increased Attitude toward physics of senior high school students is calculated using an attitude scale consisting of 18 questions. Based on the experimental class test average of 86.5% with the criteria of almost all students there is an increase and in the control class of 53.75% with the criteria of half students. This result shows that the influence of experiential learning model using simple physics kit can improve attitude toward physics compared to experiential learning without using simple physics kit.

Phylogenetic Analysis of the MS4A and TMEM176 Gene Families

Science.gov (United States)

Zuccolo, Jonathan; Bau, Jeremy; Childs, Sarah J.; Goss, Greg G.; Sensen, Christoph W.; Deans, Julie P.

2010-01-01

Background The MS4A gene family in humans includes CD20 (MS4A1), FcRβ (MS4A2), Htm4 (MS4A3), and at least 13 other syntenic genes encoding membrane proteins, most having characteristic tetraspanning topology. Expression of MS4A genes is variable in tissues throughout the body; however, several are limited to cells in the hematopoietic system where they have known roles in immune cell functions. Genes in the small TMEM176 group share significant sequence similarity with MS4A genes and there is evidence of immune function of at least one of the encoded proteins. In this study, we examined the evolutionary history of the MS4A/TMEM176 families as well as tissue expression of the phylogenetically earliest members, in order to investigate their possible origins in immune cells. Principal Findings Orthologs of human MS4A genes were found only in mammals; however, MS4A gene homologs were found in most jawed vertebrates. TMEM176 genes were found only in mammals and bony fish. Several unusual MS4A genes having 2 or more tandem MS4A sequences were identified in the chicken (Gallus gallus) and early mammals (opossum, Monodelphis domestica and platypus, Ornithorhyncus anatinus). A large number of highly conserved MS4A and TMEM176 genes was found in zebrafish (Danio rerio). The most primitive organism identified to have MS4A genes was spiny dogfish (Squalus acanthus). Tissue expression of MS4A genes in S. acanthias and D. rerio showed no evidence of expression restricted to the hematopoietic system. Conclusions/Significance Our findings suggest that MS4A genes first appeared in cartilaginous fish with expression outside of the immune system, and have since diversified in many species into their modern forms with expression and function in both immune and nonimmune cells.

Objective: This study aimed to assess the knowledge, awareness, and perception of contraception among senior pharmacy students of a public sector university in Malaysia. Methods: A cross-sectional, questionnaire-based study was conducted among senior pharmacy students. The pretested questionnaire was used to collect data from the participants over the period of 1-month. The questionnaire was divided into four sections, for gathering the information about students’ demographic data, and their knowledge, attitudes, and perception toward contraception. Data were statistically analyzed using SPSS version 20. Findings: The response rate was 68.6%. The results showed that the contraceptive knowledge was comparatively higher in year four students (P < 0.001), married respondents (P < 0.001) and those taking elective courses (P = 0.022) as compared to their respective counterparts. Majority of the students were well aware and had a positive perception about contraception. Conclusion: Overall findings reflect that the majority of the students had good knowledge, perception, and awareness about contraception. The study recommends future studies to be conducted covering different pharmacy schools across the country to further establish the results. PMID:25984548

To estimate feasibility and potential for efficacy of an individualized, exercise-focused, self-management program (i.e. Managing Mobility Outcomes In Vulnerable Seniors ( MMOVeS)), in comparison to exercise information in improving mobility after six months among seniors recently discharged from hospital. Randomized pilot study. Two McGill University-teaching hospitals. Community dwelling seniors, aged 70 years and older, recently discharged from either participating hospitals. The physiotherapy-facilitated intervention consisted of (1) evaluation of mobility capacity, (2) setting short- and long-term goals, (3) delineation of an exercise treatment plan, (4) an educational booklet to enhance mobility self-management skills, and (5) six monthly telephone calls. Control group received a booklet with information on exercises targeting mobility limitations in seniors. Mobility, pain, and health status were assessed at baseline and at six months using multiple indicators drawn from Disabilities of the Arm, Shoulder, and Hand (DASH) Score, Lower Extremity Functional Scale (LEFS) and Short-Form (SF)-36. In all, 26 people were randomized to the intervention (mean age: 81 ± 8; 39% women), and 23 were randomized to the control (mean age: 79 ± 7; 33% women). The odds ratio for the mobility outcomes combined was 3.08 and the 95% confidence interval excluded 1 (1.65-5.77). The odds ratio for pain and health perception favored the MMOVeS group, but the 95% confidence interval included the null value. This feasibility study highlights the potential for efficacy of an individualized, exercise-focused, self-management program in comparison to exercise information in improving mobility outcome for seniors. Furthermore, a home-program combining self-management skills and exercise taught with minimal supervision prove to be feasible. Finally, data from this study can be used to estimate sample size for a confirmatory trial.

It is often assumed that Chinese people tend to have a more positive attitude toward aging and old age than Americans, due to the cultural generalization of collectivism versus individualism. This study aimed to critically examine this assumption by using first-hand empirical data collected in a Chinese and an American university (standardized surveys and in-depth focus group interviews). Respectively, 980 college students in China and 332 college students in the U.S. were recruited for the standardized surveys; whereas two focus-group interviews in each country (4 participants per group) were conducted to collect more in-depth information. Contrary to the common assumption, this study revealed that Chinese students actually hold more negative attitudes toward aging and older people compared to their American peers. It was also found that females tend to hold more positive attitudes than male students across both cultures, though American female students hold more positive attitudes than Chinese female students. Chinese students' interactions with seniors are often limited to their grandparents whereas American students tend to reach out to non-grandparent seniors in larger communities. Chinese students' more negative attitudes toward aging and older people may be a result of a combination of educational, social, and economic factors-a higher level of age segregation (geographically, socially, and intellectually) and a lack of gerontological curriculum in Chinese educational system, the caregiving burden faced by the one-child generation compounded with lack of governmental support for caregiving, as well as the rising youth-oriented consumerist culture.

Seniority bosons from similarity transformations

International Nuclear Information System (INIS)

Geyer, H.B.

1986-01-01

The requirement of associating in the boson space seniority with twice the number of non-s bosons defines a similarity transformation which re-expresses the Dyson pair boson images in terms of seniority bosons. In particular the fermion S-pair creation operator is mapped onto an operator which, unlike the pair boson image, does not change the number of non-s bosons. The original results of Otsuka, Arima and Iachello are recovered by this procedure while at the same time they are generalized to include g-bosons or even bosons with J>4 as well as any higher order boson terms. Furthermore the seniority boson images are valid for an arbitrary number of d- or g-bosons - a result which is not readily obtainable within the framework of the usual Marumori- or OAI-method

Wolfers Mireille

2011-12-01

Full Text Available Abstract Background Adolescents are a risk group for acquiring sexually transmitted infections (STIs. In the Netherlands, senior vocational school students are particular at risk. However, STI test rates among adolescents are low and interventions that promote testing are scarce. To enhance voluntary STI testing, an intervention was designed and evaluated in senior vocational schools. The intervention combined classroom health education with sexual health services at the school site. The purpose of this study was to assess the combined and single effects on STI testing of health education and school-based sexual health services. Methods In a cluster-randomized study the intervention was evaluated in 24 schools, using three experimental conditions: 1 health education, 2 sexual health services; 3 both components; and a control group. STI testing was assessed by self reported behavior and registrations at regional sexual health services. Follow-up measurements were performed at 1, 3, and 6-9 months. Of 1302 students present at baseline, 739 (57% completed at least 1 follow-up measurement, of these students 472 (64% were sexually experienced, and considered to be susceptible for the intervention. Multi-level analyses were conducted. To perform analyses according to the principle of intention-to-treat, missing observations at follow-up on the outcome measure were imputed with multiple imputation techniques. Results were compared with the complete cases analysis. Results Sexually experienced students that received the combined intervention of health education and sexual health services reported more STI testing (29% than students in the control group (4% (OR = 4.3, p Conclusions Despite a low dose of intervention that was received by the students and a high attrition, we were able to show an intervention effect among sexually experienced students on STI testing. This study confirmed our hypothesis that offering health education to vocational students

To determine the prevalence and risk factors for dry eye syndrome (DES) among senior high school students in Shouguang, a county of Shandong Province, China. A cross-sectional survey was conducted in July 2010, and 1902 senior high school students were selected by multi-stage sampling to answer a questionnaire assessing the prevalence and risk factors for DES. DES was defined as the presence of a previous clinical diagnosis of DES or severe symptoms (both dryness and irritation constantly or often). Risk factors associated with DES were evaluated with a χ(2) test and logistic regression analyses. The prevalence of DES was 23.7%. In univariate analysis, myopia (P sleep quality (P = 0.007) were significantly associated with DES. In multivariate analysis, inadequate refractive correction (P sleep quality (P = 0.001, OR 1.342; 95% CI 1.054-1.709) were significant risk factors for DES. Senior high school students are a neglected population with a high prevalence of DES. Preventive measures directed against risks factors for DES among senior high school students may help reduce the prevalence and provide a positive impact on students' health.

Schiffl, Iris

2018-03-01

Information literacy—i.e. obtaining, evaluating and using information—is a key element of scientific literacy. However, students are frequently equipped with poor information literacy skills—even at university level—as information literacy is often not explicitly taught in schools. Little is known about students' information skills in science at junior and senior class level, and about teachers' competences in dealing with information literacy in science class. This study examines the information literacy of Austrian 8th, 10th and 12th grade students. Information literacy is important for science education in Austria, because it is listed as a basic competence in Austria's science standards. Two different aspects of information literacy are examined: obtaining information and extracting information from texts. An additional research focus of this study is teachers' competences in diagnosing information skills. The results reveal that students mostly rely on online sources for obtaining information. However, they also use books and consult with people they trust. The younger the students, the more they rely on personal sources. Students' abilities to evaluate sources are poor, especially among younger students. Although teachers claim to use information research in class, their ability to assess their students' information competences is limited.

Andre, Christine; Deerin, Jessica; Leykum, Luci

2017-05-02

Effective mentoring is an important component of medical student professional development. We provide a description of the mentoring program at our institution. Our institution UTHSCSA implemented a student-advising program (Veritas) with clinical faculty mentors and senior students (MiMs). The MiMs provided vertical peer mentoring to more junior students as an adjunct to faculty advising. The MiMs lead small group discussions that foster camaraderie, share academic and career information and promote professional identity. An optional MiM elective more intensively develops mentorship and leadership skills through a formal curriculum. The authors used annual survey data of all students as well as student mentors to evaluate program effectiveness. Overall, student perception of the program improved each year across multiple domains, including feeling more prepared, supported and satisfied with their overall experience in medical school. Student mentors also found the process rewarding and helpful to their future careers as physicians. The authors suggest implementing a vertical peer-mentoring program can be an effective adjunct to faculty mentoring.

Frank, Erica; Coughlin, Steven S; Elon, Lisa

2008-08-01

To understand the personal and clinical safe-sex-related knowledge, attitudes, and practices of U.S. medical students. Sixteen medical schools were selected to survey the class of 2003 based on their characteristics similar to the national average. Students were surveyed at freshman orientation, at entrance to wards, and during their senior year. The primary personal outcome was the response to the question, "Are you currently trying to practice safe sex when sexually involved? (no, not applicable/no, not trying/yes, low priority/yes, high priority)." The primary professional outcomes were answers to: 1) "How relevant do you think talking to patients about safe sex will be in your intended practice? (not at all/somewhat/highly)," and 2) "With a typical general medicine patient, how often do you actually talk about safe sex? (never-rarely/sometimes/usually-always)." A total of 2,316 students provided data, and the response rate was 80%. Personally practicing safe-sex habits was a high priority for 75% of the sexually active, single medical students, especially for women, African Americans, and those earlier in their medical education. Among seniors, 41% reported extensive training in discussing safe sex with patients, and 57% were highly confident about conducting such discussions. Overall, 55% of students believed it would be highly relevant to counsel patients about safe sex (59% of freshmen, 62% of those at entry to wards, and 41% of seniors); 73% answered all four true/false questions on human papillomavirus correctly. About half of U.S. medical students believed that counseling their patients about safe sex will not be highly relevant to their practice. These findings should be considered by those trying to interest a new generation of physicians in helping patients have safe-sex practices.

Palamar, Joseph J; Kamboukos, Dimitra

2014-11-01

Although ecstasy (MDMA) use is not as prevalent in the United States (US) as it was in the early 2000s, use remains popular among adolescents and young adults. Few recent studies have examined ecstasy use in national samples among those at particularly high risk for use-adolescents approaching adulthood. Research is needed to delineate sociodemographic correlates of use in this group. Data were examined from a nationally representative sample of high school seniors in the US (modal age = 18) from the Monitoring the Future study (years 2007-2012; weighted N = 26,504). Data from all cohorts were aggregated and correlates of recent (last 12-month) use of ecstasy were examined. Roughly 4.4% of high school seniors reported use of ecstasy within the last year. Females and religious students were consistently at lower odds for use. Black and Hispanic students, and students residing with two parents, were at lower odds for ecstasy use, until controlling for other drug use. Odds of use were consistently increased for those residing in a city, students with weekly income of >$50 from a job, and students earning >$10 weekly from other sources. Lifetime use of alcohol, cigarettes, marijuana, and other illicit drugs each robustly increased odds of ecstasy use. Subgroups of high school seniors, defined by specific sociodemographic factors, and those who have used other drugs, are currently at high risk for ecstasy initiation and use. Since ecstasy is regaining popularity in the US, prevention efforts should consider these factors.

Cyberbullying research in China is in early stage. This study describes the cyberbullying experiences of junior and senior high school students in Guangzhou, China, and to examine the risk factors associated with cyberbullying perpetrators, victims and perpetrator-victims among students. We also investigated the frequency of cyberbullying and coping strategies of student victims. Participants were 2590 students in grades 7, 8, 9 and 10 from six junior and senior high schools in October 2015 in Guangzhou, in south China, who completed a questionnaire. Data on participants' experiences with cyberbullying perpetration and victimisation during the previous 6 months were collected. Multinomial logistic regression was used to analyse factors associated with being perpetrators, victims and perpetrator-victims. In this sample, 28.0% (725) of participants reported being a perpetrator and 44.5% (1150) reported being a victim in the previous 6 months. Specifically, 2.9% (74) reported being perpetrators only, 19.3% (499) reported being victims only and 25.2% (651) reported being perpetrator-victims (both perpetrator and victim). In addition, flaming was the most common form of cyberbullying in both perpetration and victimisation. Logistic regression analyses indicated that online game addiction in participants was associated with increased odds of being a perpetrator only; no democratic parenting style in the mother and physical discipline by parents were associated with increased odds of being a victim only; male students, students with low academic achievement, those spending over 2 hours a day online, experiencing physical discipline from parents and online game addiction were associated with increased odds of both perpetration and victimisation. Cyberbullying is a common experience among Chinese junior and senior high school students. These findings add to the empirical data on cyberbullying and reinforce the urgent need for cyberbullying prevention in China

Professional determination problems of modern senior pupils

Directory of Open Access Journals (Sweden)

G.N. Danylenko

2017-03-01

Full Text Available Background. Today, young people are more focused on getting education as such, without taking into account the profession. The relevance of this study is the identification of the level of professional self-determination of senior pupils, the mechanisms of formation of professional preferences. The article contains the concept and content of professional self-determination in adolescence; the results of the study on the formation of professional self-determination in senior pupils are presented. The study conducted among 9th grade pupils of secondary schools has revealed that the further gradual self-determination of the future specialty depends not only on psychological readiness for conscious choice. Materials and methods. The study involved 982 pupils of secondary schools in Ukraine. To study the level of formation of professional readiness, there was conducted a survey on the developed questionnaire. Statistical analysis was carried out using MS Excel and SPSS 17. Results. The results showed that professional intents of 9-graders are a key feature for solving the problem of high school selection and future careers. But for most students, these intentions are contradictory due to objective reasons. Radio, television, books don’t have a significant impact on the choice of professional self-determination. Conclusions. The conducted survey is self-sufficient for the analysis of professional orientation. But the choice of profession by the students is influenced by many factors. Therefore, carrying out the studies on vocational guidance requires an integrated approach.

Lifelong learning is essential for doctors to maintain competence in clinical skills. With performance feedback, learners should be able to formulate specific and achievable learning goals in areas of need. We aimed to determine: (i) the type and specificity of medical student learning goals after a required clinical performance examination; (ii) differences in goal setting among low, average and high performers, and (iii) whether low performers articulate learning goals that are concordant with their learning needs. We conducted a single-site, multi-year, descriptive comparison study. Senior medical students were given performance benchmarks, individual feedback and guidelines on learning goals; each student was subsequently instructed to write two clinical skills learning goals. Investigators coded the learning goals for specificity, categorised the goals, and performed statistical analyses to determine their concordance with student performance level (low, average or high) in data gathering (history taking and physical examination) or communication skills. All 208 students each wrote two learning goals and most (n=200, 96%) wrote two specific learning goals. Nearly two-thirds of low performers in data gathering wrote at least one learning goal that referred to history taking or physical examination; one-third wrote learning goals pertaining to the organisation of the encounter. High performers in data gathering wrote significantly more patient education goals and significantly fewer history-taking goals than average or low performers. Only 50% of low performers in communication wrote learning goals related to communication skills. Low performers in communication were significantly more likely than average or high performers to identify learning goals related to improving performance in future examinations. The provision of performance benchmarking, individual feedback and brief written guidelines helped most senior medical students in our study to write specific

This study aimed to evaluate the association between dental students’ personality traits and stress levels in relation to dental education programs among senior dental students in University Malaya (UM) in Malaysia and National University of Singapore (NUS). A cross-sectional survey using a self-administered questionnaire was conducted on UM and NUS senior dental students. The questionnaire comprised items on demographic background, the Big Five Inventory Personality Traits (BFIPT) test and a modified Dental Environment Stress (DES) scale. Rasch analysis was used to convert raw data to interval scores. Analyses were done by t-test, Pearson correlation, and Hierarchical regression statistics. The response rate was 100% (UM=132, NUS=76). Personality trait Agreeableness (mean=0.30) was significantly more prevalent among UM than NUS students (mean=0.15, p=0.016). In NUS, Neuroticism (mean=0.36) was significantly more prevalent than in UM (mean=0.14, p=0.002). The DES mean score was higher among NUS (mean=0.23) than UM students (mean=0.07). In UM, Neuroticism was significantly correlated with stress levels (r=0.338, ppersonality traits. The correlation was strongest for personality trait Neuroticism in both schools. Hierarchical regression analysis showed that gender and Neuroticism were significant predictors for students’ stress levels (ppersonality trait were significant predictors for stress levels among selected groups of dental students in Southeast Asia. Information on students’ personality may be useful in new students’ intake, stress management counseling and future program reviews.

MS4a4B, a CD20 homologue in T cells, inhibits T cell propagation by modulation of cell cycle.

Full Text Available MS4a4B, a CD20 homologue in T cells, is a novel member of the MS4A gene family in mice. The MS4A family includes CD20, FcεRIβ, HTm4 and at least 26 novel members that are characterized by their structural features: with four membrane-spanning domains, two extracellular domains and two cytoplasmic regions. CD20, FcεRIβ and HTm4 have been found to function in B cells, mast cells and hematopoietic cells respectively. However, little is known about the function of MS4a4B in T cell regulation. We demonstrate here that MS4a4B negatively regulates mouse T cell proliferation. MS4a4B is highly expressed in primary T cells, natural killer cells (NK and some T cell lines. But its expression in all malignant T cells, including thymoma and T hybridoma tested, was silenced. Interestingly, its expression was regulated during T cell activation. Viral vector-driven overexpression of MS4a4B in primary T cells and EL4 thymoma cells reduced cell proliferation. In contrast, knockdown of MS4a4B accelerated T cell proliferation. Cell cycle analysis showed that MS4a4B regulated T cell proliferation by inhibiting entry of the cells into S-G2/M phase. MS4a4B-mediated inhibition of cell cycle was correlated with upregulation of Cdk inhibitory proteins and decreased levels of Cdk2 activity, subsequently leading to inhibition of cell cycle progression. Our data indicate that MS4a4B negatively regulates T cell proliferation. MS4a4B, therefore, may serve as a modulator in the negative-feedback regulatory loop of activated T cells.

This paper reports on the Tore Supra high velocity pellet injector which was built in Grenoble and after qualification tests installed on Tore Supra Tokomak where it is used for plasma and ablation studies. By using a two stage light gas gun (TSG) and two cells (φ = 3 mm or 4 mm), unsupported pellets pellets (1 to 3.5 10 21 atoms) made directly in the gun by > [1] have been launched into Tore Supra plasma at speeds between 2400m/s and 3400m/s with a reliability of 80%. These higher pellets velocities (> 2500 m/s) [2] are obtained by the optimization of a TSG and the search for the cryogenic conditions of freezing deuterium with good mechanical properties. In particular, the impurities concentration in deuterium during the condensation process has been studied. Several tens pellets have been injected into ohmically and ICR heated plasma and during LH current drive experiments with a good reliability in the range of 3000m/s. These experiments allowed us to extend significantly the ablation data base. Central penetrations can be reached even for high temperatures plasma (3-5 keV) and very peaked density profiles have been obtained in ohmically and ICR heated plasmas A transient improved confinement regime is then observed, which presents some features similar to the PEP regime obtained on JET.

The safeguards inspection samples from the JNFL Rokkasho Reprocessing Plant (RRP) are received and analyzed at the On Site Laboratory (OSL). Since the samples from the input accountancy tank of the RRP contain a lot of fission products, they are treated in a hot-cell line with a M/S (Master /Slave) manipulator. Special equipment and tools were used for the maintenance of the M/S manipulator, especially for the exchange of the M/S manipulator. However, the manipulator exchange work was not easy due to the limitation of the space in the OSL. For solution to this problem, a monorail and monorail hoist equipment was installed onto wall surface of analytical room close to each M/S manipulator, and then it made the exchange of M/S manipulator easy without special equipment and tools. Additionally, operator was freed from the burden of working space arranging for the exchange of M/S manipulator such as removing of analytical equipments. This report represents the improvement of operation for the exchange of M/S manipulator with installation of monorail and hoist equipment. (author)

Seniority conservation and seniority violation in the g9/2 shell

International Nuclear Information System (INIS)

Escuderos, A.; Zamick, L.

2006-01-01

The g 9/2 shell of identical particles is the first one for which one can have seniority-mixing effects. We consider three interactions: A delta interaction that conserves seniority, a quadrupole-quadrupole (Q·Q) interaction that does not, and a third one consisting of two-body matrix elements taken from experiment ( 98 Cd) that also leads to some seniority mixing. We deal with proton holes relative to a Z=50,N=50 core. One surprising result is that, for a four-particle system with total angular momentum I=4, there is one state with seniority v=4 that is an eigenstate of any two-body interaction--seniority conserving or not. The other two states are mixtures of v=2 and v=4 for the seniority-mixing interactions. The same thing holds true for I=6. Another point of interest is that, in the single-j-shell approximation, the splittings ΔE=E(I max )-E(I min ) are the same for three and five particles with a seniority conserving interaction (a well-known result), but are equal and opposite for a Q·Q interaction. We also fit the spectra with a combination of the delta and Q·Q interactions. The Z=40,N=40 core plus g 9/2 neutrons (Zr isotopes) is also considered, although it is recognized that the core is deformed

'Workshops in healing' for senior medical students: a 5-year overview and appraisal.

Science.gov (United States)

Kearsley, John H; Lobb, Elizabeth A

2014-12-01

We report upon the design, content and feedback from an interactive, experiential series of Workshops in Healing for senior medical students. Fifty-six final year medical students enrolled in 2×3 h workshops designed around the core themes of 'physician know thyself' (Workshop 1) and 'confronting suffering' (Workshop 2). Of the 56 students who initially enrolled, 48 students completed both workshops and provided a written open-ended reflection of their learning experience. The study, undertaken over a consecutive 5-year period (2008-2012), employed an emergent, qualitative design using thematic analysis of the reflective comments. We found that the design and content of both workshops promoted transformative learning for these final year medical students. Students identified the following benefits: (1) the opportunity to reaffirm their commitment to their chosen career path; (2) the value of listening to other students share their stories; (3) the importance of the timing of the workshops to occur after exams; (4) the use of various mediums such as art, poetry, music and contemporary/classic literature to present concepts of suffering and healing; and (5) the creation of a safe and confidential space. Students reported that these innovative workshops gave them a renewed sense of drive and enthusiasm for their chosen career. They highlighted the importance of addressing an aspect of medicine (healing) not covered in the traditional medical curriculum. Workshops in Healing helped them to rediscover a deeper meaning to medicine and their roles as future healthcare professionals. Published by the BMJ Publishing Group Limited.

Effects of an intensive clinical skills course on senior nursing students' self-confidence and clinical competence: A quasi-experimental post-test study.

Science.gov (United States)

Park, Soohyun

2018-02-01

To foster nursing professionals, nursing education requires the integration of knowledge and practice. Nursing students in their senior year experience considerable stress in performing the core nursing skills because, typically, they have limited opportunities to practice these skills in their clinical practicum. Therefore, nurse educators should revise the nursing curricula to focus on core nursing skills. To identify the effect of an intensive clinical skills course for senior nursing students on their self-confidence and clinical competence. A quasi-experimental post-test study. A university in South Korea during the 2015-2016 academic year. A convenience sample of 162 senior nursing students. The experimental group (n=79) underwent the intensive clinical skills course, whereas the control group (n=83) did not. During the course, students repeatedly practiced the 20 items that make up the core basic nursing skills using clinical scenarios. Participants' self-confidence in the core clinical nursing skills was measured using a 10-point scale, while their clinical competence with these skills was measured using the core clinical nursing skills checklist. Independent t-test and chi-square tests were used to analyze the data. The mean scores in self-confidence and clinical competence were higher in the experimental group than in the control group. This intensive clinical skills courses had a positive effect on senior nursing students' self-confidence and clinical competence for the core clinical nursing skills. This study emphasizes the importance of reeducation using a clinical skills course during the transition from student to nursing professional. Copyright © 2017. Published by Elsevier Ltd.

Exploring Gender Difference in Motivation, Engagement and Enrolment Behaviour of Senior Secondary Physics Students in New South Wales

Science.gov (United States)

Abraham, Jessy; Barker, Katrina

2015-02-01

Although substantial gender differences in motivation, engagement and enrolment behaviour are frequently reported in the international physics education literature, the majority of studies focus on students who intend to choose physics for their future study. The present multi-occasional study examines the gender difference in motivation, engagement and enrolment behaviour among senior secondary students from New South Wales schools who have already chosen to study physics. It examines whether the differences reflect differences of degree in these dimensions, or differences of kind for these students. Fine-grained analyses at module-specific level of the senior secondary physics curriculum indicated that the differences do not represent differences of kind. That is, girls' and boys' perceptions of the key facets of motivation, sustained engagement and choice intentions in relation to physics seemed to be qualitatively the same. However, there were differences in the degree to which boys and girls are motivated, although the pattern was inconsistent across the four modules of the senior secondary physics curriculum. Girls' motivation, engagement and sustained enrolment plans in relation to physics were found equal to or higher than boys' at various time points through the course. These findings highlight the need to change the existing gender-biased stereotype that students perceive physics as a male domain and that subjective motivation, engagement and enrolment plans will always report higher measures for males. The results have implications for intervention strategies aimed at sustaining student motivation in physics. The potential implications of the findings for practitioners and researchers are discussed.

Dempsey, GM, Gibson, NV, Sykes, D, Pryjmachuk, BC, and Turner, AP. Match demands of senior and junior players during International Rugby League. J Strength Cond Res 32(6): 1678-1684, 2018-This study aims to quantify and compare the positional game demands of international junior and senior rugby league competition for the first time. Global positioning system (GPS) and video analysis were used to track 118 elite male rugby league players (57 seniors aged 28.7 ± 4.4 years; 61 juniors aged 17.2 ± 0.5 years) over 10 international matches (6 senior; 4 junior) characterized as either forwards (n = 67) or backs (n = 51). There were significant increases in the offensive carries (0.18 cf. 0.09 n·min; r = 0.56) and defensive tackles (0.36 cf. 0.23 n·min; r = 0.3) between senior and junior players, and forwards and backs (0.16 cf. 0.09; r = 0.34 and 0.41 cf. 0.14; r = 0.52), respectively. Running demands were significantly greater in backs than forwards (independent of playing level) for total distance (6,962 ± 1,263 m cf. 4,879 ± 1,824 m; r = 0.55), individualized high-speed distances (310 ± 158 m cf. 250 ± 171 m; r = 0.2), high-intensity accelerations (28.7 ± 12.1 m·s cf. 21.9 ± 11.7 m·s; r = 0.27), and decelerations (57.2 ± 18.3 m·s cf. 43.0 ± 17.8 m·s; r = 0.38). Positional differences were eliminated when reported relative to minutes played. From a practical perspective, although running demands relative to time on the pitch may prepare junior players for senior competition, it is not representative of the increased body mass and contact frequency within the senior game. Coaches should therefore reflect these differences within their physical preparation programs to prepare junior athletes accordingly for progression to the senior level.

2003-09-01

The prevalence rate of psychopathology and the relationship between psychopathology and some socio-demographic variables and consolidated current drug use were studied in 600 randomly selected senior secondary school students in Ilesa, south-western Nigeria. The 30-item version of the General Health Questionnaire and the WHO student drug use questionnaire were administered for the study. The findings revealed that the prevalence of psychopathology among the study population was 39.5%. There were significant positive associations between psychopathology and belonging to low socio-economic status, coming from a polygamous family and self-rated poor academic performance. The results also showed that although psychopathology was commoner amongst respondents who were engaged in current use of psychoactive substances than those who were not, the difference was not significant. The implications of these findings within the context of the limitations of the study and the importance of effective preventive and therapeutic student mental health services are discussed.

Lateral impact tests were performed using seven male post-mortem human subjects (PMHS) to characterize the force-deflection response of contacted body regions, including the lower abdomen. All tests were performed using a dual-sled, side-impact test facility. A segmented impactor was mounted on a sled that was pneumatically accelerated into a second, initially stationary sled on which a subject was seated facing perpendicular to the direction of impact. Positions of impactor segments were adjusted for each subject so that forces applied to different anatomic regions, including thorax, abdomen, greater trochanter, iliac wing, and thigh, could be independently measured on each PMHS. The impactor contact surfaces were located in the same vertical plane, except that the abdomen plate was offset 5.1 cm towards the subject. The masses of the sleds and the force- deflection characteristics of the energy-absorbing interface material between the sleds were set to provide the impactor sled with a velocity profile that matched the average driver door velocity history produced in a series of side NCAP tests. Impactor padding was also selected so that average ATD pelvis and thorax responses from the same series of side NCAP tests were reproduced when the ATD used in these tests was impacted using the average door-velocity history. Each subject was first impacted on one side of the body using an initial impactor speed of 3 m/s. If a post-test CT scan and strain-gage data revealed two or fewer non-displaced rib fractures, then the PMHS was impacted on the contralateral side of the body at a speed of 8 m/s or 10 m/s. The results of tests in the 3 m/s and 8 m/s conditions were used to develop force-deflection response corridors for the abdomen, force history response corridors for the pelvis (iliac wing and greater trochanter), the midthigh, and the thorax. Response corridors for the lateral acceleration of the pelvis were also developed. Future work will compare side impact ATD

The Minorities Striving and Pursuing Higher Degrees of Success (MS PHD'S) Professional Development Program in Earth system science (ESS) is a model initiative for improving the retention of underrepresented minority (URM) students in STEM fields. Entering its ninth cohort, MS PHD'S remains committed to helping URM undergraduate and graduate students achieve outstanding careers in ESS. MS PHD'S facilitates URM student achievement through a three-phase program designed to increase student exposure to the ESS community. By engaging in a series of professional development and skill building exercises, peer-to-peer community building activities, participation in scientific society conferences and workshops, mentoring by URM and other scientists, and a virtual community, URM students gain the confidence and support necessary to achieve their academic goals and enter the ESS workforce. Since its inception, MS PHD'S continues to support 189 participants. Of these 189 participants, 35 have advanced from undergraduate and graduate academic pathways to completion of their PhD and another 60 are currently enrolled in doctoral programs. MS PHD'S maintains close ties with program alumni to further support retention, inclusivity, and broadening participation of URM students and graduates in STEM activities. Its model is built on reengaging alumni to become mentors and leaders for each new cohort as well as facilitating valuable opportunities for alumni to advance in their ESS related academic and professional career pathways.

1. The metabolic fate of 4-bromoaniline (4-BrA) was investigated in rat following intraperitoneal administration at 50 mg kg(-1) using HPLC-TOF-MS/MS. 2. The sensitivity provided by the use of TOF-MS/MS, aided by the distinctive isotope pattern resulting from the presence of the bromine substituent in the molecule, enabled the detection of many previously uncharacterized metabolites in the samples. 3. Several groups of minor metabolites were detected in the urine that corresponded to a number of isomeric hexose and di-hexose-containing conjugates (possibly glucosides and diglucosides) of 4-BrA. 4. As well as hexose and di-hexose conjugates of 4-BrA, several further groups of metabolites that also contained either a sulphamate or sulphate group in addition to the sugar moieties were also detected.

Doctors in Greece face the possibility of encountering a person that has suffered torture, especially since the high rates of refugees' and migrants' inflows that took place over the last years. In order to assess the awareness and the knowledge of doctors and senior medical students in Greece regarding a manual on effective investigation and documentation of torture such as Istanbul Protocol (official United Nation document since 1999), a cross-sectional study was conducted using a structured anonymous questionnaire. The sample was doctors practicing in public hospitals in Greece, doctors volunteering at a non-governmental organization (NGO) and undergraduate medical students in their final year of studies in the Medical School of National and Kapodistrian University of Athens. The data were analyzed using IBM SPSS version 23, using descriptive statistics and statistical significance tests.In a total of 289 participants, the mean total score of Istanbul Protocol knowledge was 4.43 ± 1.104 (the maximum possible score was 10) and the mean total score of Istanbul Protocol awareness was 2.04 ± 1.521 (the maximum possible score was 10). The most important conclusion was that among doctors and senior medical students, there seem to be knowledge, awareness, and information deficit about Istanbul Protocol and several issues relating to torture. The overall research outcome highlights the need for the development of a relevant informative/educational program, in order to cover the corresponding existing needs of the population of doctors in Greece.

Serum levels of fully sialylated C4-binding protein (FS-C4BP) are remarkably elevated in patients with epithelial ovarian cancer (EOC) and can be used as a marker to distinguish ovarian clear cell carcinoma from endometrioma. This study aimed to develop a stable, robust and reliable liquid chromatography-hybrid mass spectrometry (UPLC-MS/MS) based diagnostic method that would generalize FS-C4BP as a clinical EOC biomarker. Glycopeptides derived from 20 μL of trypsin-digested serum glycoprotein were analyzed via UPLC equipped with an electrospray ionization time-of-flight mass spectrometer. This UPLC-MS/MS-based diagnostic method was optimized for FS-C4BP and validated using sera from 119 patients with EOC and 127 women without cancer. A1958 (C4BP peptide with two fully sialylated biantennary glycans) was selected as a marker of FS-C4BP because its level in serum was highest among FS-C4BP family members. Preparation and UPLC-MS/MS were optimized for A1958, and performance and robustness were significantly improved relative to our previous method. An area under the curve analysis of the FS-C4BP index receiver operating characteristic curve revealed that the ratio between A1958 and A1813 (C4BP peptide with two partially sialylated biantennary glycans) reached 85%. A combination of the FS-C4BP index and carbohydrate antigen-125 levels further enhanced the sensitivity and specificity. © 2017 The Authors.

The purpose of this study was to understand what perceptions junior and senior engineering & technology students have about change, change readiness, and selected attributes, skills, and abilities. The selected attributes, skills, and abilities for this study were lifelong learning, leadership, and self-efficacy. The business environment of today is dynamic, with any number of internal and external events requiring an organization to adapt through the process of organizational development. Organizational developments affect businesses as a whole, but these developments are more evident in fields related to engineering and technology. Which require employees working through such developments be flexible and adaptable to a new professional environment. This study was an Explanatory Sequential Mixed Methods design, with Stage One being an online survey that collected individuals' perceptions of change, change readiness, and associated attributes, skills, and abilities. Stage Two was a face-to-face interview with a random sample of individuals who agreed to be interviewed in Stage One. This process was done to understand why students' perceptions are what they are. By using a mixed-method study, a more complete understanding of the current perceptions of students was developed, thus allowing external stakeholders' such as Human Resource managers more insight into the individuals they seek to recruit. The results from Stage One, one sample T-test with a predicted mean of 3.000 for this study indicated that engineering & technology students have a positive perceptions of Change Mean = 3.7024; Change Readiness Mean = 3.9313; Lifelong Learning Mean = 4.571; Leadership = 4.036; and Self-Efficacy Mean = 4.321. A One-way ANOVA was also conducted to understand the differences between traditional and non-traditional student regarding change and change readiness.

2013-06-01

This study examined the relationship between the changes of physical fitness across the 3-year spectrum of senior high school study and academic performance measured by standardized tests in Taiwan. A unique dataset of 149 240 university-bound senior high school students from 2009 to 2011 was constructed by merging two nationwide administrative datasets of physical fitness test performance and the university entrance exam scores. Hierarchical linear regression models were used. All regressions included controls for students' baseline physical fitness status, changes of physical fitness performance over time, age and family economic status. Some notable findings were revealed. An increase of 1 SD on students' overall physical fitness from the first to third school year is associated with an increase in the university entrance exam scores by 0.007 and 0.010 SD for male and female students, respectively. An increase of 1 SD on anaerobic power (flexibility) from the first to third school year is positively associated with an increase in the university entrance exam scores by 0.018 (0.010) SD among female students. We suggest that education and school health policymakers should consider and design policies to improve physical fitness as part of their overall strategy of improving academic performance.

To examine the weight trajectory of students over 4 years of college. Anthropometric assessments were completed at the beginning and end of students' freshman year and the end of senior year to calculate body mass index. Questionnaires assessing weight-related behaviors were completed in senior year. Of the original 117 students, 86 remained in the study for 4 years. Body mass index was significantly higher at the end of senior year (mean, 24.84; SD, 4.46) vs the beginning of freshman year (mean, 23.59; SD, 4.01; t[85] = 5.61; P Students' mean weight gain was 4.38 kg and the sample increased from 23% to 41% overweight/obese. No significant associations were found between BMI and lifestyle factors. This study suggests that students gain weight throughout college, which highlights the need for weight control interventions to target more than just freshman college students.

2011-12-01

Full Text Available Abstract Background Stigma toward schizophrenia is a substantial barrier to accessing care and adhering to treatment. Provisions to combat stigma are important, but in Japan and other developed countries there are few such provisions in place that target parents of adolescents. The attitudes of parents are important to address as first schizophrenic episodes typically occur in adolescence. In overall efforts to develop an education program and provisions against stigma, here we examined the relationship between stigma toward schizophrenia and demographic characteristics of parents of junior and senior high school students in Japan. The specific hypothesis tested was that contact and communication with a person with schizophrenia would be important to reducing stigma. A questionnaire inquiring about respondent characteristics and which included a survey on stigma toward schizophrenia was completed by 2690 parents. Results The demographic characteristics significantly associated with the Devaluation- Discrimination Measure were family income, occupation, presence of a neighbor with schizophrenia, and participation in welfare activities for people with mental illness (p Conclusions Stigma toward schizophrenia among parents of junior and senior high school students was in fact significantly stronger among members of the general public who had had contact with individuals with schizophrenia. In addition, stigma was associated with family income.

Characterization and Clearance of m/s Sigyn

International Nuclear Information System (INIS)

Jiselmark, Jonatan; Vreede, Patrick

2016-01-01

M/s Sigyn was a 2044 ton ship that transported contaminated material between 1982 and 2013. Most of the transports were with spent nuclear fuel between Swedish nuclear power plants and the Swedish fuel repository, Clab. In addition to spent fuel, m/s Sigyn also transported big contaminated components, from nuclear power plants in Europe, to Studsvik for analysis or decontamination and melting. She also transported components from Swedish nuclear power plants to final disposal of short lived waste, SFR. Even though all transported items have been cleaned, checked and wrapped with plastics, some activity ended up as contamination onboard. In December 2013 it was decided that m/s Sigyn was subject for decommissioning due to her age. This Paper describes the method in which the activity onboard m/s Sigyn was characterized and clearance levels were calculated. This method for radiological characterization and clearance has recently been developed in Sweden, the method is efficient in that it does not need a big pre characterization survey. Only the nuclide distribution and history of the object, is needed to start the final survey. In the future there will be further development of the method, making it possible to reduce the number of measurements even more. This will further optimize the method and reduce the cost for final surveys and clearance. (authors)

Behavioral Indexes of Test Anxiety in Mathematics among Senior High School Students

Directory of Open Access Journals (Sweden)

DANIEL MACÍAS-MARTÍNEZ

2008-12-01

Full Text Available The study of Mathematics has been and is still a source of frustration and anxiety for a large number of students. The purpose of this study was to inquire systematically upon levels of test anxiety through behavioral and physiological procedures before and after a Math test, in 205 senior high school students. Academic worries were assessed by means of a computerized task based on the emotional version of the Stroop paradigm designed ex profeso to measure school anxiety (Hernández-Pozo, Macías & Torres, 2004. The Stroop task was administered, along with recordings of blood pressure and pulse, before and after the first Math test of the course. Academic general scores were inverse to the behavioral anxiety level, however the best Math scores were associated to middle levels of behavioral anxiety. Contradictory findings between academic performance in Math and global score, and the apparent lack of gender difference in anxiety measured through behavioral procedures suggests the need to review the generality of previous assertions relating academic performance inversely with levels of anxiety of high school students.

Medical students face numerous stressors during their clinical years, including difficult clinical events. Fostering resilience is a promising way to mitigate negative effects of stressors, prevent burnout, and help students thrive after difficult experiences. However, little is known about medical student resilience. To characterize medical student resilience and responses to difficult clinical events during clinical training. Sixty-two third-year (MS3) and 55 fourth-year (MS4) University of Chicago medical students completed surveys in 2016 assessing resilience (Connor Davidson Resilience Scale, CD-RISC 10), symptoms of burnout, need for resilience training, and responses to difficult clinical events. Medical student mean resilience was lower than in a general population sample. Resilience was higher in males, MS4s, those without burnout symptoms, and students who felt able to cope with difficult clinical events. When students experienced difficult events in the clinical setting, the majority identified poor team dynamics among the most stressful, and agreed their wellbeing was affected by difficult clinical events. A majority also would prefer to discuss these events with their team later that day. Students discussed events with peers more than with attendings or residents. Students comfortable discussing stress and burnout with peers had higher resilience. Most students believed resilience training would be helpful and most beneficial during MS3 year. Clinical medical student resilience was lower than in the general population but higher in MS4s and students reporting no burnout. Students had some insight into their resilience and most thought resilience training would be helpful. Students discussed difficult clinical events most often with peers. More curricula promoting medical student resilience are needed.

The student clinical experience is rich, yet challenges arise in providing experiences where leadership skills can be developed and used in nursing practice. To increase student confidence and enhance student ability to safely and effectively prioritize, delegate, and implement care for numerous patients, a simulation-based learning (SBL) experience was developed. The SBL experience involves multiple patient simulators, case study analysis, and a debriefing session. Ninety-seven senior nursing students participated in this program. Students reported through Likert surveys to either "agree" or "strongly agree" that the SBL was well organized (87%, n = 84), prompted realistic expectations (59%, n = 57), the scenarios were believable (73%, n = 71), case studies increased understanding (66%, n = 64), and that the SBL experience increased understanding of prioritizing and delegating care (69%, n = 67). Seventy-eight percent (n = 76) reported "more confidence in ability to work as a team" and 55% (n = 52) reported "more confidence in prioritizing and delegating care."

The geometric and electronic ground-state structures of 30 isomers of six MS 4 molecules (M=Group 8 metals Fe, Ru, Os, Hs, Sm, and Pu) have been studied by using quantum-chemical density functional theory and correlated wavefunction approaches. The MS 4 species were compared to analogous MO 4 species recently investigated (W. Huang, W.-H. Xu, W. H. E. Schwarz, J. Li, Inorg. Chem. 2016, 55, 4616). A metal oxidation state (MOS) with a high value of eight appeared in the low-spin singlet T d geometric species (Os,Hs)S 4 and (Ru,Os,Hs)O 4 , whereas a low MOS of two appeared in the high-spin septet D 2d species Fe(S 2 ) 2 and (slightly excited) metastable Fe(O 2 ) 2 . The ground states of all other molecules had intermediate MOS values, with S 2- , S 2 2- , S 2 1- (and O 2- , O 1- , O 2 2- , O 2 1- ) ligands bonded by ionic, covalent, and correlative contributions. The known tendencies toward lower MOS on going from oxides to sulfides, from Hs to Os to Ru, and from Pu to Sm, and the specific behavior of Fe, were found to arise from the different atomic orbital energies and radii of the (n-1)p core and (n-1)d and (n-2)f valence shells of the metal atoms in row n of the periodic table. The comparative results of the electronic and geometric structures of the MO 4 and MS 4 species provides insight into the periodicity of oxidation states and bonding. © 2017 Wiley-VCH Verlag GmbH & Co.

When it comes to sexuality and norms, young Indonesians are becoming more open. Concern about this is related to the rapid increase in HIV prevalence in Indonesia, especially in Papua and West Papua Provinces. While much research has been conducted among youth who have left school, little is known about senior high school students' sexuality and sexual practices in these provinces. Using qualitative and quantitative data, we explore perspectives on and experiences of sexuality, contraceptive use, unintended pregnancy and unsafe abortion among 1082 Year 11 students from 16 senior high schools in both provinces. Findings suggest that around 38.3% of students reported having had sexual intercourse and 36.5% of these having had their first sexual encounter before they were 15 years old. Furthermore, contraceptive use among sexually active students was very low. Around 32% of female students who reported having had sexual intercourse also reported having an unintended pregnancy and the majority of them had had unsafe abortions. The paper points to the implications of students' high-risk sexual behaviours for HIV prevention.

Adolescents in the industrial world are becoming less physically active and are increasingly adopting a sedentary life-style in front of computers and television screens. to determine self-related health, physical activity, sleeping habits, prevalence of overweight, and body complaints in Australian senior high school students. Participants were 466 high school students aged 15-17 years enrolled in academic and vocational programs. A questionnaire was completed at two senior high schools with questions about weight and height, health, physical activity, type of physical activity/sport, intensity, sleeping habits, and possible injuries or complaints during the last three months. Seventy seven percent of the high school students participated in sports on a regular basis. Compared with vocational programs, more males and females in academic programs participated in sports (71% and 80% respectively) (p = .036). Males reported significantly better health than females (p sleep was reported in 82.1% of males and in 76.6% of females. In males, 44.3% were often sleepy in the daytime (females 56.6%, p sleep are factors with significant positive effect on good health, whereas overweight is a negative factor. Proper sleep habits and higher physical activity levels should be promoted among high school students, and TV viewing time and video game use restricted. Additionally, schools should provide opportunities for young people to participate in a wider range of physical activities that address their individual needs while promoting the health benefits of engaging in regular exercise.

Full Text Available Senior market is one of the most prospective segments to be targeted for hospitality industry, including hotel business in Indonesia. This research aims to examine senior guest satisfaction toward service quality of four and five star hotels in Surabaya. Employing derived satisfaction method, guest satisfaction is measured by comparing guests' expectation with the perception. Five variables of service quality are used to measure the service provided, namely reliability, responsiveness, assurance, empathy and tangibles. The result shows that there is a gap between senior market's expectation and perception, in which the expectation is above the perception. Thus, it can be concluded that respondents have not satisfied yet with the quality of service delivered. Abstract in Bahasa Indonesia : Senior market merupakan salah satu pasar yang cukup menjanjikan bagi bisnis jasa, termasuk bagi bisnis jasa hotel di Indonesia. Penelitian ini bertujuan mengukur kepuasan tamu lanjut usia yang menginap di hotel bintang 4 dan 5 di Surabaya. Kepuasan diukur menggunakan metode derived satisfaction dengan cara membandingkan harapan dan persepsi senior market terhadap kualitas layanan. Kualitas layanan didasarkan pada lima variabel, yaitu keterandalan, kecepatanggapan, jaminan, empati, dan fasilitas fisik. Hasil penelitian menunjukkan bahwa terdapat gap antara harapan dan persepsi, dimana harapan lebih besar daripada persepsi, sehingga dapat disimpulkan bahwa responden belum puas dengan seluruh atribut layanan yang disediakan.

Background While there is an increasing pool of literature documenting the benefits of near-peer tutoring programme, little is known about the benefits for junior and senior peer tutors. Knowledge of the peer tutors' perceived benefits at different levels of seniority will aid in the development of a near-peer tutoring programme that will better fulfil both curricula and personal aspirations of near-peer tutors. We, therefore, investigated the perceived benefits of participation in a near-peer tutoring programme for junior as well as senior near-peer tutors. Methods Pre- and post-participation questionnaires were distributed to near-peer tutors after their clinical skills teaching sessions with Phase I undergraduate medical students. The Peer Tutor Assessment Instrument questionnaires were distributed to the 1) students, and to the 2) near-peer tutors (junior and senior) after each teaching and learning session for self-evaluation. Results The senior near-peer tutors felt that their participation in the programme had enhanced their skills (p=0.03). As a whole, the near-peer tutors were more motivated (Pre 5.32±0.46; Post 5.47±0.50; p=0.210) to participate in future teaching sessions but did not expect that having teaching experiences would make teaching as their major career path in the future (Pre 4.63±1.07; Post 4.54±0.98; p=0.701). The senior near-peer tutors were evaluated significantly higher by the students (p=0.0001). Students' evaluations of near-peer tutors on the domain of critical analysis was higher than self-evaluations (p=0.003). Conclusions Generally, the near-peer tutors perceived that they have benefited most in their skills enhancement and these near-peer tutors were scored highly by the students. However, senior near-peer tutors do not perceive that the programme has a lasting impact on their choice of career path.

Full Text Available Background: The accurate knowledge of generic medicine issues among future prescribers will enhance the prescribing of cost-effective medicines. This study aimed to explore the knowledge and perception of senior medical students about the generic medicines. Methodology: A cross-sectional study was conducted among 237 senior medical students (final year students and interns using a validated self-administered questionnaire. The collected data were analyzed using Statistical Package for the Social Sciences version 20 for windows and comparison of difference was done using linear by linear association. A p value of less than 0.05 was taken as statistically significant. Results: The average age (standard deviation of the respondents was 23.54 (1.39 years. Almost 5% of respondents correctly answered the question regarding the regulatory limits for bioequivalence. Almost two-thirds of respondents correctly agreed that generic medicine is bioequivalent to a brand-name medicine, and 79.3% and 72.5% of respondents correctly agreed that the medicine should be present in the same dosage form and same dose, respectively, as the brand-name medicines. However, almost half of the respondents had impression that brand-name medicines are required to meet higher safety standard than generic medicines. Almost 90% of respondents felt that advertisement by the drug companies would influence the use of brand-name medicine and they need more information about generic medicine. Conclusion: This study highlights the negative perception and knowledge deficit among the respondents. The students’ responses to almost all the statements were almost similar to the respondents’ academic year (final year students and interns, gender and nationality.

The survey of the nuclear sciences in the curricula of senior high schools

International Nuclear Information System (INIS)

Ujeno, Yowri; Okamura, Seizo; Inaoka, Mariko; Nakase, Yoshiaki.

1994-01-01

To know senior high school education and recognition of nuclear science, questionnaire survey was made in a total of 619 university, college or occupational school students who graduated from senior high schools before 1993. Female students accounted for 95% (n=589) because females are believed to more strongly affect the next generation than males. Of these students, 92.7% had graduated from the ordinary course of senior high school. Students who majored in physical science accounted for 38.6%. In the physical science curriculum, nuclear science had been selected in 27.8% of the students. Among the students who majored in physical science, 38.1% did not memorize the learning of basic physical science at all, and only 25% memorized the learning. These results suggest that the learning of physical science is extremely insufficient. However, such an unfamiliar phenomenon of physical science seems to be closely related to the examination system to universities and colleges. The reason why few people give a debate upon atomic power generation is that people have no accurate knowledge because of their insufficient school learning of nuclear science. Only 19.1% had taken lessons of atomic power generation in the curriculum of social science. Serious problems of the senior high school educational system are pointed out. (N.K.)

Research indicates that having electronic resources readily available increases learners' ability to make clinical decisions and confidence in patient care. This mixed-method, descriptive pilot study collected data about senior prelicensure nursing students using smartphones, a type of mobile electronic device (MED), in the clinical area. The smartphones contained nursing diagnosis, pharmacology, and laboratory information; an encyclopedia; and the MEDLINE database. Student (n = 7) data about smartphone use during a 10-week clinical rotation were collected via student-recorded usage logs and focus group recordings. Staff nurses' (n = 5) perceptions of students' use of smartphones for clinical educational resources were collected by anonymous survey. Both the focus group transcript and staff surveys were evaluated and the themes summarized by content analysis. Positive results and barriers to use, such as cost and technological comfort levels, are discussed. The results may help nurse educators and administrators initiate further research of MEDs as a clinical resource. Copyright 2012, SLACK Incorporated.

The Advancing Potential of Tutor Technologies in the Senior Students Training in the High School

Y. A. Lyakh

2013-01-01

Full Text Available The paper is devoted to the tutoring system in the modern high school. The system in question is based on the complex developmental educational technology of personalized teaching, aimed at identifying students’ educational motives and interests, and creating individual training programs and educational reflection. The important role is given to the tutor’s competence both in profile teaching and creating the comfortable communicative and stimulating educational environment. The author reveals the structural and functional implementation model of tutoring technologies, and observes its performance in the course of education quality monitoring of senior students in the profile high schools. The effectiveness of the personalized tutor technology system is demonstrated in three different aspects: the students’ education quality and communicative educational activity; development of tutors’ competence in monitoring the profile education quality; and students’ self-assessment and professional self-determination. The experimental research demonstrates that the implementation model of tutor technologies facilitates education quality improvement in the high school.

Full Text Available One of Maillard reaction products formed in the production of ammonia caramel is 4(5-methylimidazole (4-MeI classified as carcinogen. A method of 4-MeI determination based on ion-pair extraction and derivatisation with isobutyl chloroformate with subsequent gas chromatography-tandem mass spectrometry analysis was proposed. Tandem mass spectrometry was applied to reduce the influence of matrix and increase the selectivity and sensitivity of the method. Triple quadrupole GC-MS system was used for this study. The collision energies were optimized for MRM mode. The detection (LOD and quantification limits (LOQ of the elaborated method were 17 and 37.8 μg kg−1, respectively, repeatability was <15% RSD for analyzed caramel samples, and the recovery for 4-MeI was 101%. Comparison of MS/MS with SIM detection on the same instrument proved almost 30 times lower LODs achieved by tandem mass spectrometry compared to SIM. Described method can be routinely used for monitoring 4-MeI as a quality and safety marker in the production of ammonia caramel.

Senior medical students represent future physicians who commonly refer patients for diagnostic imaging studies that may involve ionizing radiation. The radiology curriculum at the University of British Columbia provides students with broad-based knowledge about common imaging examinations. The purpose of this study was to investigate students' awareness of radiation exposures and risks. An anonymous multiple-choice cross-sectional questionnaire was distributed to final year medical students to assess knowledge of radiation from common diagnostic examinations and radiation-related risks following completion of the longitudinal radiology curriculum, carried out over the four years of medical training. Sixty-three of 192 eligible students participated (33% response rate). The majority felt that knowledge of radiation doses of common imaging examinations is somewhat or very important; however, only 12% (N = 8) routinely discuss radiation-related risks with patients. While all respondents recognized children as most sensitive to the effects of radiation, only 24% (N = 15) correctly identified gonads as the most radiation-sensitive tissue. Almost all respondents recognized ultrasound and MRI as radiation free modalities. Respondents who correctly identified the relative dose of common imaging examinations in chest x-ray equivalents varied from 3-77% (N = 2 - 49); the remaining responses were largely underestimates. Finally, 44% (N = 28) correctly identified the excess risk of a fatal cancer from an abdominal CT in an adult, while the remainder underestimated this risk. Medical students acknowledge the importance of radiation-related issues to patient care. While almost all students are familiar with radiation-free modalities, many are not familiar with, and commonly underestimate, the relative doses and risks of common imaging studies. This may expose patients to increasing imaging investigations and exposure to radiation hazards.

Background This study examined associations between perceived neighborhood illicit drug selling, peer illicit drug disapproval and illicit drug use among a large nationally representative sample of U.S. high school seniors. Methods Data come from Monitoring the Future (2007–2011), an annual cross-sectional survey of U.S. high school seniors. Students reported neighborhood illicit drug selling, friend drug disapproval towards marijuana and cocaine use, and past 12-month and past 30-day illicit drug use (N = 10,050). Multinomial logistic regression models were fit to explain use of 1) just marijuana, 2) one illicit drug other than marijuana, and 3) more than one illicit drug other than marijuana, compared to “no use”. Results Report of neighborhood illicit drug selling was associated with lower friend disapproval of marijuana and cocaine; e.g., those who reported seeing neighborhood sales “almost every day” were less likely to report their friends strongly disapproved of marijuana (adjusted odds ratio [AOR] = 0.38, 95% CI: 0.29, 0.49) compared to those who reported never seeing neighborhood drug selling and reported no disapproval. Perception of neighborhood illicit drug selling was also associated with past-year drug use and past-month drug use; e.g., those who reported seeing neighborhood sales “almost every day” were more likely to report 30-day use of more than one illicit drug (AOR = 11.11, 95% CI: 7.47, 16.52) compared to those who reported never seeing neighborhood drug selling and reported no 30-day use of illicit drugs. Conclusions Perceived neighborhood drug selling was associated with lower peer disapproval and more illicit drug use among a population-based nationally representative sample of U.S. high school seniors. Policy interventions to reduce “open” (visible) neighborhood drug selling (e.g., problem-oriented policing and modifications to the physical environment such as installing and monitoring surveillance cameras) may

Arachidonic acid, the origin of the eicosanoids family, occurs in biological samples as free acid and as ester in lipids. Free arachidonic acid is oxidized to numerous metabolites by means of enzymes including cyclooxygenase (COX). Arachidonic acid esterified to lipids is attacked by reactive oxygen species (ROS) to generate numerous oxidized arachidonic acid derivatives. Generally, it is assumed that ROS-derived arachidonic acid derivatives are distinct from those generated by enzymes such as COX. Therefore, ROS-generated eicosanoids are considered specific biomarkers of oxidative stress. However, there are serious doubts concerning a strict distinction between the enzyme-derived eicosanoids and the ROS-derived iso-eicosanoids. Prominent examples are prostaglandin F2α (PGF2α) and 15(S)-8-iso-prostaglandin F2α (15(S)-8-iso-PGF2α) which have been originally considered to exclusively derive from COX and ROS, respectively. There is convincing evidence that both COX and ROS can oxidize arachidonic acid to PGF2α and 15(S)-8-iso-PGF2α. Thus, many results previously reported for 15(S)-8-iso-PGF2α as exclusive ROS-dependent reaction product, and consequently as a specific biomarker of oxidative stress, require a careful re-examination which should also consider the analytical methods used to measure 15(S)-8-iso-PGF2α. This prominent but certainly not the only example underlines more than ever the importance of the analytical chemistry in basic and clinical research areas of oxidative stress. In the present work, we report analytical protocols for the reliable quantitative determination of 15(S)-8-iso-PGF2α in human biological samples including plasma and urine by mass spectrometry coupled to gas chromatography (GC-MS, GC-MS/MS) after specific isolation of endogenous 15(S)-8-iso-PGF2α and the externally added internal standard [3,3',4,4'-(2)H4]-15(S)-8-iso-PGF2α by immunoaffinity column chromatography (IAC). 15(S)-8-iso-PGF2α esterified to plasma lipids is

Academic dreamers to leaders: The emergence of the mathematics and science for minority students ((MS)(2)) program at Philips Academy Andover

Science.gov (United States)

Beckham, Jerrell K.

(MS)2 is a summer program for high achieving minority students interested in math and science careers. It was started in 1977. The Program is located at Phillips Academy in Andover Massachusetts. Phillips Academy is one of the nation's oldest college preparatory schools. The school was founded in 1778. Current U.S. President George Bush attended Phillips Academy and his father before him. The students in (MS)2 attend Phillips Academy in the summertime, along with regular Summer Session students. The (MS)2 Program represents about a fifth of the students at Phillips Academy Summer Session. At present the program is made up of African Americans, Latinos, and Native American students who attend a number of different public schools throughout the nation. This dissertation explores the experiences of students in this program spanning nearly a quarter of a central. My research seeks to understand and shred additional light on how certain outreach programs might help along the pipeline in regard to improving minority representation in mathematics and science fields. Also, this narrative hopes to not only paints a more complex pictures of the experiences of minorities in schools, but seeks to serve the larger public interest by challenging some of the popular renditions and myths of the failure of Blacks, Latino/as, and Native Americans in schooling (Ogbu 2003), as oppose to certain aspects of schooling and society continuing to failing them.

Applicant interviews for urology residency positions are a stressful and costly process for students, faculty, and staff. We conducted a prospective survey to better determine what urology applicants perceive as an ideal interview process to gain sufficient knowledge about a training program. A questionnaire was anonymously completed by all urology residency applicants interviewing at the Medical College of Wisconsin from 2007 to 2013. Questionnaire subject headings included "ideal interview format," "factors contributing to understanding the residency program," and "factors contributing to final rank list order." Questionnaires were distributed to and completed by 221 senior medical students applying for a urology residency position. Most respondents (>80%) reported they would prefer to partake in 5 to 7 faculty interviews in an office setting with the total interview process spanning half to three-fourths of the workday. Spending time with current residents was considered the most valuable tool to acquire knowledge about a residency program. The most important criteria when ranking a program were resident satisfaction, resident operative experience, and perceived strength of faculty. Academic urology programs may wish to consider applicant ideals when organizing residency interviews. Interaction with current residents appears to be the most valuable resource allowing applicants to garner knowledge about a urology training program.

2018-03-14

U.S. seniors' digital health and everyday technology use when their health declines are unknown. Longitudinal cohort using the National Health and Aging Trends Study, a nationally representative, annually administered sample of community-dwelling Medicare beneficiaries (n = 4,037). We used difference-in-differences to assess the adjusted difference (AD) in technology use from 2011 to 2014 between those with and without health declines. Health decline measures included new-onset dementia; new-onset depression; decreases in activities of daily living (ADLs), short physical performance battery (SPPB), grip strength, and self-reported health; relocation to nursing facility; increased hospitalizations; and new-onset comorbidity. Digital health included use of the Internet to research health conditions, contact clinicians, fill prescriptions, and address insurance matters. Between 2011 and 2014, seniors experiencing health decline used various digital health technologies at low absolute rates (range: 1%-20%). Between 2011 and 2014, use of everyday technology decreased significantly among seniors with new-onset dementia (from 73% to 51%; AD, -26%), decreased ADLs (from 76% to 67%; AD, -10%), decreased SPPB (from 88% to 86%; AD, -3%), and relocation to a nursing facility (from 49% to 22%; AD, -31%) compared to seniors without comparable decline (all p seniors with new-onset probable dementia (from 9% to 4%; AD, -6%) and decreased SPPB (from 24% to 25%; AD, -4%; all p senior experiences predicts technology use, which may allow better targeting of digital health to specific seniors. Seniors with new dementia, relocation to a nursing home, and declining physical performance seem especially poor candidates for technology interventions.

To determine if pharmacist involvement within a senior dining program benefits diners by addressing their medication-related questions, using educational sessions, and providing individual consultations. Catholic Charities Senior Dining sites in central Minnesota. Pharmacists went to three senior dining sites, providing educational sessions and individual consultations to independently living senior diners. Pharmacists developed a program, in a nontraditional setting, that used educational sessions and individual consultations to assist seniors with their medication-related questions. The number of diner questions, significant issues raised, issues addressed, and level of diner satisfaction. Pharmacists made 36 visits from January to December 2009. During those visits they presented educational talks to 3,089 diners, and 12.4% of all diners spoke individually with pharmacists. Pharmacists addressed 581 questions or concerns from 384 diners. Significant issues were noted in 25.8% of individual consultations (144 questions). The most common significant issues included: adverse drug reactions (59), indications without treatment (27), and drug interactions (23). Nonopioid analgesics, antilipemics, and antihypertensive medications were most commonly involved in significant issues. Satisfaction surveys were strongly positive, with 97% indicating pharmacists had addressed their medication-related concern; only 3% did not reply. Almost half (42.7%) of satisfaction surveys indicated the diner would change something as a result of meeting with the pharmacist. Pharmacist availability in a nontraditional setting can assist seniors with addressing potentially significant medication-related issues. Independently living seniors will seek out information from a pharmacist in a convenient setting.

The geometric and electronic ground-state structures of six MS₄ molecules (M = group-8 metals Fe, Ru, Os, Hs, Sm, and Pu) have been studied by using quantum-chemical density-functional and correlated wave-function approaches. The MS₄ species are compared to analogous MO₄ species recently investi-gated (Inorg. Chem. 2016, 55: 4616). Metal oxidation state (MOS) of high value VIII appears in low- spin singlet Td geometric species (Os,Hs)S₄ and (Ru,Os,Hs)O₄, whereas low MOS=II appears in high- spin septet D_2d species Fe(S₂)₂ and (slightly excited) metastable Fe(O₂)₂. The ground states of all other molecules have intermediate MOS values, containing S^2-, S₂^2-, S2^1- (and resp. O^2--, O^1-, O₂^2-, O₂^1-) ligands, bonded by ionic, covalent and correlative contributions.

In today's dental school curricula, an increasing amount of time is dedicated to technological advances, and preventive dentistry topics may not be adequately addressed. Freshman (D1) students participated in a new Introduction to Preventive Dentistry course, which consisted of didactic lectures, active learning breakout sessions and case-based studies. The goal of this study was to determine if D1 dental students completing the course had a better knowledge and comfort level with basic preventive dentistry concepts and caries risk assessment than the upcoming graduating senior dental students. Following the completion of the course, D1 students were administered a survey that assessed their comfort level describing preventive dentistry topics to patients. This was immediately followed by an unannounced examination over the same topics. Senior (D4) students, who had not taken a formal course, reported statistically significant higher comfort levels than D1 students. However, the D4s scored significantly lower in all of the examination areas than the D1 students. Higher scores in D1s may have been due to recent exposure to the course material. However, the basic nature of the content-specific questions should be easily answered by novice practitioners educating their patients on oral disease prevention. As the current data shows lower content-specific scores of basic preventive dentistry knowledge amongst graduating D4 students, this may indicate a need for more guidance and education of students during the patient care. This study showed that implementation of a formalised course for D1 students can successfully ameliorate deficiencies in knowledge of preventive dentistry topics. © 2014 John Wiley & Sons A/S.

2017-04-01

Full Text Available In the article the functional analysis of future music art teachers’ training for singing activity of comprehensive school senior students is depicted. This issue is very important because improving educators and musicians’ training contributes not only to professional selfactualisation, but also to young generation’s encouraging for thorough learning music art works and their creative development in the process of group music tuitions. Extracurricular singing activity also plays an important part. It reveals art images to students, enriching creativity experience, forms the spiritual world, develops independent thinking, awakens creativity. The author points out the main functions of future music art teachers’ training. They are system and value, information, communication, creative and transformative, projective functions. The special attention is paid to characterizing the features of each function. The author claims that system and value function relates to the necessity to analyze the results of the educational process that contributes to productive solving problems by students and main tasks of music training. Information function is a subject background of art music teachers’ and pedagogical activities. Communicative function is realized in a teacher’s ability to develop the student’ initiative to plan cooperative activities, to be able to distribute duties, to carry out instructions, to coordinate cooperative activities, to create special situations for the implementation of educational influence. The analysis of pedagogical and methodological literature shows that The creative and transformative function is manifested in the creative use of pedagogical and methodological ideas in specific pedagogical conditions. The projective function is thought to promote the most complete realization of content of comprehensive and art education.

Full Text Available Background: Considering the importance of anger, aggression, violence and other misbehaviours in schoolchildren education, the present study was conducted to evaluate the knowledge and practice of students in Isfahan province regarding violence, in order to figure out the required interventions for violence-reduction. Methods: In a survey during 2008-2009, 5500 junior and senior high school students of Isfahan province were assessed in a multistage sampling process to determine their level of knowledge about various types of violent behaviors, causes of violence, its consequences, and preventive behaviors. Validity and reliability of the data collection tool (questionnaire were assessed. Results: The study revealed that the mean scores of violent behaviors knowledge, knowledge of violent behavior outcomes, and knowledge of violence preventive behaviors, were 6.6 ± 2.1, 5.5 ± 1.9, and 4.7 ± 1.3, respectively. Sources of violent behaviors in 92% of urban students and 89% of rural students were personal reasons and family behaviors, and 85% of urban and 88% of rural students considered mass media and computer games blameworthy, and the differences were statistically significant in all cases (P < 0.0001. In terms of practice, overall, 69.7% of girls and 84.2% of boys had violent behaviors. Physical and verbal violence were 31.3% and 40.7%in girls, and 66% and 52.8% in boys, respectively (intersexes P values were P < 0.001 and P = 0.7 respectively, and intra-sex P value was P < 0.0001. Conclusions: Results showed that girls and city dwellers were more aware of recognizing violent behaviors, outcomes, and causes, compared with boys and villagers, and in terms of general practice, violence was observed among boys more than girls. Further complementary studies in this area seem required.

Therefore, to aid in the design and implementation of effective prevention programmes, it is important to understand the role of the family in influencing sexual behaviour among school-going adolescents. To evaluate the relationship between family communications about HIV/AIDS and sexual activity and condom use among school-going adolescents in Accra, Ghana. A sample of 894 students (56.9% girls, 43.1% boys; mean age = 17.4 years, SD = 1.40) at two senior secondary schools in Accra completed a modified version of the Youth Risk Behavior Survey (YRBS) questionnaire, a self-administered instrument developed by the Centers for Disease Control and Prevention. Analytical techniques utilized included logistic regression and chi-square. Twenty-five percent of the participants reported being sexually experienced, and 73.6% had talked about HIV/AIDS with parents or other family members. Of the sexually experienced students, 64.7% initiated first sexual intercourse by age 16; and 55.7% did not use a condom at last sexual intercourse. Bivariate analysis showed significant gender differences in sexual activity, condom use, and family communication about HIV/AIDS. Logistic regression analysis showed that student-family communication about HIV/AIDS was not associated with sexual activity. However, communication about HIV/AIDS between students and parents or other family members increased the odds of using a condom at last sexual intercourse. The findings of this study suggest that prevention programmes that seek to educate Ghanaian school-going adolescents about sexual risk behaviour must strongly encourage communication about HIV/AIDS between students and family members.

2016-07-01

The design of products and processes is an important area in engineering. Students in engineering schools learn fundamental principles in their courses but often lack an opportunity to apply these methods to real-world problems until their senior year. This article describes important elements that should be incorporated into a senior capstone design course. It includes a description of the general principles used in engineering design and a discussion of why students often have difficulty with application and revert to trial and error methods. The structure of a properly designed capstone course is dissected and its individual components are evaluated. Major components include assessing resources, identifying projects, establishing teams, understanding requirements, developing conceptual designs, creating detailed designs, building prototypes, testing performance, and final presentations. In addition to the course design, team management and effective mentoring are critical to success. This article includes suggested guidelines and tips for effective design team leadership, attention to detail, investment of time, and managing project scope. Furthermore, the importance of understanding business culture, displaying professionalism, and considerations of different types of senior projects is discussed. Through a well-designed course and proper mentoring, students will learn to apply their engineering skills and gain basic business knowledge that will prepare them for entry-level positions in industry.

Full Text Available The article presented at the conference is the study of the problems of upbringing and education of senior pupils from the Carpathian mountain area. Namely the author investigates the students’ readiness for choosing the teaching profession and willingness to work at rural mountain schools. Despite the big number of teachers in the labor market of Ukraine, now the system of education meets an acute issue dealing with the selection to the pedagogical specialties talented creative young people who actually choose teaching profession by nature and strong personal will. Today there are very few teachers whose level of commitment to perform professional duties in Ukrainian education is really high, and this is especially true about mountain school teachers. This phenomenon can be partially explained by the fact that teaching profession has low prestige in our society for the recent decades (Ukrainian teachers are not well-paid, their working conditions in rural Carpathian schools leave much to be desired. Therefore the problem of readiness of high school students to perform professional-pedagogical duties is of particular relevance. The author analyzes the psychological and pedagogical basis of the presented problem, defines the essence and structure of the notion “readiness for choosing the teaching profession”. In the context of solving this issue one of the important conditions the author considers the comprehensive development of senior school students, particularly the development of their creative abilities.

Full Text Available Today thanks to the technological advances in information technology the scenario of utilization of digital cytology has radically changed. New competitive systems, such as client-server architectures are now available in digital cytology. Their application in telemedicine should be investigated. A new interactive tool designed for the final destination user (the cytopathologist has been proposed. Taking into account the different expertise of the subjects of the study, the investigation was focused both on the senior cytopathologist and on the younger student pathologist. The methodology was tested on 10 students of a Master in cytopathology and on 3 senior cytopathologists. The study showed that the use of digital cytology applications is effective and feasible for telediagnosis. In particular, the study on younger and senior expert investigators showed that, although they interacted with the novel technology of the virtual slide in a different manner, all of them reached the objective of a "correct diagnosis". This investigation, in consideration of the effectiveness of the digital cytology, also showed other indirect and tangible cost-beneft and quantitative advantages.

Full Text Available One dominant factor on how well students learn mathematics is the quality of teaching. Studies have shown that typical mathematics classroom is frosted with teaching technique that centered on explain – practice – memorize. There is a paucity particularly in Nigeria. This study therefore, investigated the effect of brain-based learning strategy on the achievement regarding the learning of Mathematics of 522 Senior Secondary School Students in Oyo State, Nigeria. The moderator effect of cognitive style was also examined on independent variable (instructional strategy and dependent variable (mathematics achievement. The study adopted a pretest-posttest non-equivalent control group design in a quasi – experimental setting. The ANCOVA statistic was used to analyzed the data collected fro the study. The result revealed significant main effect of treatment, (F(1,510 = 75.0; P < 0.05, cognitive style (F(1,510 = 23.78; P < 0.05 and significant interaction effect of treatment and cognitive style (F(1,510 = 5.027; P < 0.05 on achievement in mathematics. The result showed that brain-based instructional strategy enhanced students’ achievement in mathematics more than the conventional lecture method. It is therefore recommended that Teachers of mathematics should adopt the strategy in teaching mathematics in senior secondary school.

To determine the sexual behavioral pattern, consequences, and adopted solutions among senior secondary schools students in Ojo military barracks, Lagos. This was a cross-sectional study of 400 senior secondary schools students in Ojo military barracks, Lagos, selected using a multistage sampling technique. Data was collected using pre-tested, self-administered semi-structured questionnaires. Data was analysed using statistical package for social sciences version 17. Tests of statistical significance were carried out using χ2-test, and a p-value of sexual intercourse and were influenced mainly by peer pressure (p=0.0000). Their age at first sexual intercourse ranged between 10-19 years. Ten (6.5%) of the respondents (all males) had their sexual debut with a commercial sex worker. More girls 41 (56.2%) than boys 12 (14.8%), were forced into sexual intercourse (p=0.0000). Over half of the sexually active respondents had at least two sexual partners for either sex. Findings from this study have shown that young people living in the barracks indulged in sexual activity at very early ages and engaged in risky sexual behavior. We therefore recommend an improved multi-sectoral approach in reproductive health and sexually transmitted infections including HIV/AIDS education.

Communities are exploring ways to increase transportation coordination to improve access for seniors. One such effort is a brokered transportation system in which one agency serves as the central point of contact for ride information or actually arranging transportation for clients of multiple programs by use of a combination of transportation services. A team of social work faculty and students from the University of New Hampshire (UNH) Social Work Outreach Center, a center that provides service learning opportunities to students, collaborated with a local coalition to investigate the specific transportation needs of the region's senior citizens. A total of 641 people participated in the survey. Results indicate that the study population experiences problems reliably meeting daily living needs due to inconsistent or unavailable private and public transportation options. Study findings also indicate the promising potential of brokered transportation systems, particularly for isolated seniors in rural and suburban areas with relatively limited public and private transportation options.

Multiple toilet grab-bar configurations are required by people with a diverse spectrum of disability. The study purpose was to determine toilet grab-bar preference of healthy seniors, seniors with a hip replacement, and seniors post-stroke, and to determine the effect of each configuration on centre of pressure (COP) displacement during toilet transfers. 14 healthy seniors, 7 ambulatory seniors with a hip replacement, and 8 ambulatory seniors post-stroke participated in the study. Toilet transfers were performed with no bars (NB), commode (C), two vertical bars (2VB), one vertical bar (1VB), a horizontal bar (H), two swing-away bars (S) and a diagonal bar (D). COP was measured using pressure sensitive floor mats. Participants rated the safety, ease of use, helpfulness, comfort and preference for instalment. 2VB was most preferred and had the smallest COP deviation. Least preferred was H and NB. C caused largest COP displacement but had favourable ratings. The preference and safety of the 2VB should be considered in the design of accessible toilets and in accessibility construction guidelines. However these results need to be verified in non-ambulatory populations. C is frequently prescribed, but generates large COP deviation, suggesting it may present an increased risk of falls.

Maheshwari, Bhoomika; Jain, Ashok Kumar

2015-01-01

In this paper, we focus on the isomers that arise due to the seniority selection rules and the role played by generalized seniority when multi-j configurations are involved. In particular, we concentrate on explaining the B(E2) values in the semi-magic isomeric chains by using a simple approach. In this paper, we study the B(E2) variation of these isomers by using the generalized seniority scheme, applicable to many-j degenerate orbits. We show that the isomers known to arise mainly from the high-j intruder orbitals, do require the configuration mixing as an essential requirement

Full Text Available Introduction: Tooth decay is the most common chronic disease of man in the world and dentists should receive the capability to accurately diagnose of tooth decay during the training courses. In addition to clinical examination, the panoramic view and intraoral radiography is usually used for the caries detection. Therefore, the detection of caries on X-ray images can have a role in treatment planning. Methods: In this analytical study, 10 panoramic radiographies that randomly selected, separately given to 30 senior dental students and 2 professors (in order to determine the gold standard. Data were analyzed using SPSS 17 software, diagnostic tables and indexes were prepared and the results were analyzed by Kappa test. Moreover, in order to determine the agreement between the professors and students about the depth of the decay the weighted kappa coefficient was used. Results: The kappa value about detection of presence or absence of proximal caries between professors and students's diagnosis was 0.428 (P value=0.001. Diagnostic sensitivity, specificity, positive predictive value and negative predictive value obtained by students in caries detection were %47, %91.9, %63 and %85.3, respectively. Coefficient of agreement in detection of depth diagnosis obtained by professors and students was 0.361(p value=0.000. Conclusion: The diagnostic capability of senior dental students about caries detection was fair and depth diagnosis was slight.

4-Methoxydiphenylmethane (4-MDM), a selective augmenter of Leukotriene A4 Hydrolase (LTA4H), is a new anti-inflammatory compound for potential treatment of chronic obstructive pulmonary disease (COPD). Currently, there is no liquid chromatography tandem mass spectrometric (LC-MS/MS) method for the quantification of 4-MDM. A major barrier for developing the LC-MS/MS method is the inability of electrospray ionization (ESI) and atmospheric pressure chemical ionization (APCI) to ionize 4-MDM due to its hydrophobicity and lack of any functional group for ionization. With the advent of atmospheric pressure photoionization (APPI) technique, many hydrophobic compounds have been demonstrated to ionize by charge transfer reactions. In this study, a highly sensitive ultrapressure liquid chromatography tandem mass spectrometry assay using atmospheric pressure photoionization (UPLC-APPI-MS/MS) for the quantifications of 4-MDM in rat plasma has been developed and validated. 4-MDM was extracted from the plasma by solid phase extraction (SPE) and separated chromatographically using a reverse phase C8 column. The photoionization (PI) was achieved by introducing anisole as a dopant to promote the reaction of charge transfer. The assay with a linear range of 5 (LLOQ)-400ngmL(-1) met the regulatory requirements for accuracy, precision and stability. The validated assay was employed to quantify the plasma concentrations of 4-MDM after an oral dosing in Sprague Dawley (SD) rats. Copyright © 2016 Elsevier B.V. All rights reserved.

The AGU Hydrology Section Student Subcommittee (H3S), the student body of the AGU hydrology section, caters to the needs of students and early career scientists whose research interests contain a hydrological component. The past two years, H3S organized a Student and Early Career Scientist conference addressing both the technical and research needs of young hydrologists. Over the past several years, H3S organized pop-up sessions in Water Sciences and Social Dimensions of Geosciences which allowed young hydrologists to share and learn from their collective experiences. Social events like the early career social mixer, co-organized with CUAHSI, led to increased networking opportunities among peers. Continuous social media engagement led to a general dialogue within the community over varied issues including research productivity, gender equality, etc. Ice-breaker events between junior and senior academics encouraged young hydrologists to talk with their academic crushes and continuously seek out mentorship opportunities. Collating our past experiences, we ponder over our accomplishments, failures, and opportunities to improve representation of early career hydrologists within the community.

Full Text Available The nature of motivation and learning strategy use is vital to improving student learning outcomes. This study was intended to explore the motivational beliefs and learning strategy use by Liberian junior and senior high school students in connection with their academic performance. It also solicited students’ self-reports about presumed factors hindering their learning. Utilizing a cross-sectional quantitative research design, 323 participants took part in the study from 2 counties. Motivated Strategies for Learning Questionnaire (MSLQ was adapted and 12 potential learning hindrances were identified and used as instruments. Data analyses were conducted using SPSS 17.0. The results showed the motivational belief component of extrinsic goal orientation as the most preferred belief and test anxiety was the least possessed belief. Rehearsal strategies were found to be the most frequently used, while help seeking was reported to be the least strategy considered. The result also showed significant relationships between the two constructs. In addition, the study found some learning hindrances. A number of conclusions as well as some practical recommendations for action relative to the improvement of student performance have been advanced.

For all playing positions, Senior athletes presented greater total distance, accelerations, and decelerations than U20 players. For high-intensity distance and sprints, only central defender and midfielder senior players presented greater values than U20 players. Senior players demonstrated higher values in all locomotor activities in comparison to U17 players, irrespective of playing positions. Except for central defenders that presented similar total distance, sprint distance, and number of accelerations between U20 and U17, the majority of match external loads evaluated in all playing positions were greater in U20 than in U17 players. These results provide useful information for player development and should be used to establish appropriate match-specific conditioning drills according to age categories.

This study investigated the critical thinking dispositions and skills of senior nursing students. Study participants were students enrolled in associate (n = 137), baccalaureate (n = 102), and RN-to-BSN (n = 66) programs accredited by the Korean Ministry of Education. The California Critical Thinking Disposition Inventory (CCTDI) and California Critical Thinking Skills Test (CCTST) were used. A comparison of the CCTDI scores revealed a statistically significant difference between the students enrolled in different programs (F = 4.159, p = 0.017), as did a comparison of the CCTST scores (F = 24.205, p critical thinking skills to make the decisions required of them in their nursing practice. In line with this, when conducting a survey of the effectiveness of nursing education, the necessity of critical thinking skills cannot be overlooked. In fact, the National League for Nursing Accrediting Commission (NLNAC) (1999) and American Association of Colleges of Nursing (AACN) (1998) require the concept of critical thinking be included as one of the core elements of curricula and that it be measured as an outcome when evaluating nursing education. In 1998, during the evaluation of colleges of nursing conducted by the South Korean Council for University Education, several universities presented the fostering of critical thinking as one of the terminal learning goals of nursing education based on the idea that critical thinking is important not only in the nursing workplace, but also in nursing education. To evaluate the effectiveness of Korea's current nursing education curriculum, focus was placed on current students in South Korea's three systems of nursing education. Each curriculum's effectiveness can be evaluated by indexing critical thinking dispositions and skills. This article intends to offer insight into the first steps necessary in reorganizing nursing education by comparing these evaluations of each of the three systems. To this end, we conducted a comparative

Ga mS n clusters were generated by laser ablation of a solid sample of Ga 2S 3. The resulting molecules were analyzed in a time-of-flight mass spectrometer. In addition to atomic species, the spectra exhibited evidence for the existence of GaS3+, GaS4+, GaS5+, and GaS6+ clusters. The potential neutral and cationic structures of the observed Ga mS n clusters were computationally investigated using a density-functional approach. Reference is made to the kinetic pathways required for production of clusters from the starting point of the stoichiometric molecule or molecular ion. Cluster atomization enthalpies are compared with bulk values from the literature.

BALTIMORE’S M.S. LEVY AND SONS: Straw Hat Makers to the World, 1870-1960

2008-01-01

Full Text Available From 1860 to 1960, Baltimore was an important center of the men’s ready-to- wear clothing industries. German-speaking Jews created many businesses that manufactured and sold underwear, men’s suits, and specialty items like hats and umbrellas. The straw hat making firm started by M.S. Levy is an interesting example of a Baltimore-based, family-owned niche business that existedfor 90 years, through three generations ofa singlefamily. The M.S. Levy and Sons story has two main chapters. The first covers the period from its founding by Michael Simon Levy in the 1870s through his son Julius’ death in 1926. This is the story of ascension. A premonition about the coming popularity of straw hats, together with a small but important technological breakthrough, positioned a family and a small industry for significant expansion. The second period began in 1930 with the introduction of wool felt hats and the death of William, M.S. Levy’s oldest son, and includes the Great Depression, unionization, merger, third generation leadership, and finally, in 1959, the family’s withdrawal from the industry. This later period, as told by grandsons of the founder, is the story of struggle followed by decline.

LC-MS/MS quantification of 7α-hydroxy-4-cholesten-3-one (C4) in rat and monkey plasma.

7α-hydroxy-4-cholesten-3-one (C4) is an oxidative enzymatic product of cholesterol metabolism via cholesterol 7α-hydroxylase, an enzyme also known as cholesterol 7-alpha-monooxygenase or cytochrome P450 7A1 (CYP7A1). C4 is a stable intermediate in the rate limiting pathway of bile acid biosynthesis. Previous studies showed that plasma C4 levels correlated with CYP7A1 enzymatic activity and could serve as a biomarker for bile acid synthesis. Here we developed and qualified a simple and robust high-throughput method using liquid chromatography coupled with tandem mass spectrometry (LC-MS/MS) to quantify C4 in rat and monkey plasma. As C4 being an endogenous compound, this method used calibration standards in 50/50: acetonitrile/water (v/v). In order to mimic the incurred samples, quality control samples were prepared in the authentic plasma. Stable isotope labeled C4 (C4-d 7 ) was used as the internal standard. The sample volume for analysis was 20μL and the sample preparation method was protein precipitation with acetonitrile. The average endogenous C4 concentrations, from 10 different lots of rat and monkey plasma, were 53.0±16.5ng/mL and 6.8±5.6ng/mL, respectively. Based on these observed endogenous C4 levels, the calibration curve ranges were established at 1-200ng/mL and 0.5-100ng/mL for rat assay and monkey assay, respectively. The method was qualified with acceptable accuracy, precision, linearity, and specificity. Matrix effect, recovery, and plasma stability of bench-top, freeze-thaw, and long-term frozen storage were also evaluated. The method has been successfully applied to pre-clinical studies.

Full Text Available Background: While there is an increasing pool of literature documenting the benefits of near-peer tutoring programme, little is known about the benefits for junior and senior peer tutors. Knowledge of the peer tutors’ perceived benefits at different levels of seniority will aid in the development of a near-peer tutoring programme that will better fulfil both curricula and personal aspirations of near-peer tutors. We, therefore, investigated the perceived benefits of participation in a near-peer tutoring programme for junior as well as senior near-peer tutors. Methods: Pre- and post-participation questionnaires were distributed to near-peer tutors after their clinical skills teaching sessions with Phase I undergraduate medical students. The Peer Tutor Assessment Instrument questionnaires were distributed to the 1 students, and to the 2 near-peer tutors (junior and senior after each teaching and learning session for self-evaluation. Results: The senior near-peer tutors felt that their participation in the programme had enhanced their skills (p=0.03. As a whole, the near-peer tutors were more motivated (Pre 5.32±0.46; Post 5.47±0.50; p=0.210 to participate in future teaching sessions but did not expect that having teaching experiences would make teaching as their major career path in the future (Pre 4.63±1.07; Post 4.54±0.98; p=0.701. The senior near-peer tutors were evaluated significantly higher by the students (p=0.0001. Students’ evaluations of near-peer tutors on the domain of critical analysis was higher than self-evaluations (p=0.003. Conclusions: Generally, the near-peer tutors perceived that they have benefited most in their skills enhancement and these near-peer tutors were scored highly by the students. However, senior near-peer tutors do not perceive that the programme has a lasting impact on their choice of career path.

To investigate the effect of APOE epsilon4 on different cognitive domains in a population of Greek patients with multiple sclerosis (MS). A total of 125 patients with MS and 43 controls were included in this study and underwent neuropsychological assessment with Rao's Brief Repeatable Battery. All patients with MS were genotyped for APOE. The effect of APOE epsilon4 on different cognitive domains was investigated. Fifty-one percent of patients with MS were cognitively impaired. E4 carriers had a sixfold increase in the relative risk of impairment in verbal learning vs noncarriers (OR 6.28, 95% CI 1.74 to 22.69). This effect was domain-specific and was not observed in other cognitive domains assessed by the battery. We found an association of APOE epsilon4 with impaired verbal learning in patients with multiple sclerosis.

To identify the cause of an outbreak of foot pain syndrome among students from a senior high school in Foshan. We defined a suspect case as onset of foot pain/numbness with unknown reason among students and teachers in a school of Foshan city, from February 10 to March 16, 2014. A suspect case was noticed as having both food pain and numbness. All the cases were searched through reviewing medical records in the nearby hospitals and school's clinic, also the records of absenteeism in school. Clinical information was collected from all the students, using a standardized questionnaire. Daily temperature was collected from all the students, between January 1 and March 31, 2014. A 1 : 2 individual matched case-control study was conducted to identify related risk factors on this epidemic. We interviewed all the cases and controls on their diet, physical activities and measures used for warming. A total of 407 case-students were identified, with an attack rate (AR) as 26.5%. The AR was 37.3% in girls, compared to 12.9% in boys. The difference was statistically significant (χ² = 115.1, P < 0.01). Boarding students had a higher AR (31.8%) than the commuting students (16.2%). The difference was statistically significant (χ² = 43.2, P < 0.01). In girls, boarding students had higher AR (46.1%) than those commuting students (18.5%). The difference was statistically significant (χ² = 61.4, P < 0.01). No statistically significant difference was found between boarding or commuting students in boys. Outdoor temperature was coming down from 23 °C on February 6 to 6 °C on February 13, but gradually rose to 23 °C on February 28. There was a positive relationship (r = 0.65, P = 0.002) noticed between daily maximum temperature and the number of cases during February 13-28. Results from this case-control study showed that factors as lacking physical activities (OR = 2.8, 95% CI: 1.5-5.6), feeling cold in bed (OR = 3.0, 95% CI: 1.3-7.0) and having experienced similar symptoms (OR

Conflict Management in Student Groups - a Teacher’s Perspective in Higher Education

Directory of Open Access Journals (Sweden)

Markus Borg

2011-12-01

Full Text Available Students working in groups is a commonly used method of instruction in higher education, popularized by the introduction of problem based learning. As a result, management of small groups of people has become an important skill for teachers. The objective of our study is to investigate why conflicts arise in student groups at the Faculty of Engineering at Lund University and how teachers manage them. We have conducted an exploratory interdepartmental interview study on teachers' views on this matter, interviewing ten university teachers with different levels of seniority. Our results show that conflicts frequently arise in group work, most commonly caused by different levels of ambition among students. We also found that teachers prefer to work proactively against conflicts and stress the student’s responsibility. Finally, we show that teachers at our faculty tend to avoid the more drastic conflict resolution strategies suggested by previous research. The outcome of our study could be used as input to future guidelines on conflict management in student groups.

Coteaching with senior students – a way to refine teachers' PCK for teaching chemical bonding in upper secondary school

Science.gov (United States)

Schultze, Felix; Nilsson, Pernilla

2018-04-01

During the last decade there has been on-going discussions about students' declining interest and low achievement in science. One of the reasons suggested for this decline is that teachers and students have different frames of reference, whereby teachers sometimes communicate science in the classroom in a way that is not accessible to the students. There is a lack of research investigating the effects of coteaching with senior students in science in upper secondary schools. To improve teaching and to narrow the gap between teachers' and students' different frames of references, this study investigates how an experienced chemistry teacher gains and refines her pedagogical content knowledge (PCK) by cooperating with two grade 12 students (age 18) as coteachers. The teacher and the two coteachers coplanned, cotaught and coevaluated lessons in chemical bonding in a grade 10 upper secondary class. Findings indicate that the coteachers contributed with their own learning experiences to help the teacher understand how students perceive difficult concepts. In such way, the coteachers were mediating between the teacher and the students, thus bridging the gap between the teacher and the students' frames of references. The teachers' PCK was refined which in turn lead to improved teaching strategies.

This study compared the sensitivity of various separation and ionization methods, including gas chromatography with an electron ionization source (GC-EI), liquid chromatography with an electrospray ionization source (LC-ESI), and liquid chromatography with a silver ion coordination ion spray source (LC-Ag(+) CIS), coupled to a mass spectrometer (MS) for steroid analysis. Chromatographic conditions, mass spectrometric transitions, and ion source parameters were optimized. The majority of steroids in GC-EI/MS/MS and LC-Ag(+) CIS/MS/MS analysis showed higher sensitivities than those obtained with other analytical methods. The limits of detection (LODs) of 65 steroids by GC-EI/MS/MS, 68 steroids by LC-Ag(+) CIS/MS/MS, 56 steroids by GC-EI/MS, 54 steroids by LC-ESI/MS/MS, and 27 steroids by GC-ESI/MS/MS were below cut-off value of 2.0 ng/mL. LODs of steroids that formed protonated ions in LC-ESI/MS/MS analysis were all lower than the cut-off value. Several steroids such as unconjugated C3-hydroxyl with C17-hydroxyl structure showed higher sensitivities in GC-EI/MS/MS analysis relative to those obtained using the LC-based methods. The steroids containing 4, 9, 11-triene structures showed relatively poor sensitivities in GC-EI/MS and GC-ESI/MS/MS analysis. The results of this study provide information that may be useful for selecting suitable analytical methods for confirmatory analysis of steroids. Copyright © 2015 John Wiley & Sons, Ltd.

Safety Culture and Senior Leadership Behavior: Using Negative Safety Ratings to Align Clinical Staff and Senior Leadership.

Science.gov (United States)

O'Connor, Shawn; Carlson, Elizabeth

2016-04-01

This report describes how staff-designed behavior changes among senior leaders can have a positive impact on clinical nursing staff and enhance the culture of safety in a community hospital. A positive culture of safety in a hospital improves outcomes for patients and staff. Senior leaders are accountable for developing an environment that supports a culture of safety. At 1 community hospital, surveys demonstrated that staff members did not view senior leaders as supportive of or competent in creating a culture of safety. After approval from the hospital's institutional review board was obtained, clinical nurses generated and selected ideas for senior leader behavior change. The new behaviors were assessed by a convenience sample survey of clinical nurses. In addition, culture of safety survey results were compared. Risk reports and harm events were also measured before and after behavior changes. The volume of risk and near-miss reports increased, showing that clinical staff were more inclined to report events after senior leader communication, access, and visibility increased. Harm events went down. The culture of safety survey demonstrated an improvement in the senior leadership domain in 4 of 6 units. The anonymous convenience survey demonstrated that staff members recognized changes that senior leaders had made and felt that these changes positively impacted the culture of safety. By developing skills in communication, advocacy, visibility, and access, senior leaders can enhance a hospital's culture of safety and create stronger ties with clinical staff.

Senior citizens retrofits

Energy Technology Data Exchange (ETDEWEB)

1985-02-01

The Seniors' Residential Retrofitting Project was Yukon's most ambitious CREDA, funded demonstration with a total cost of $460,000. The project undertook to demonstrate energy-efficient retrofitting techniques in 38 homes and two apartment complexes for senior citizens. At the same time, the project strove to train Yukon tradesmen in retrofitting techniques, thus creating a local industry and employment within this industry. To this end, two training courses were given for local tradesmen and contractors, the first of their kind in Canada. The training part of the project was given equal importance as the actual demonstration part. Three levels of retrofit work were done on the homes of senior citizens. Level one included caulking, weatherstripping, furnace servicing, and installation of water flow restrictors, water heater blankets and timers. The level two retrofit included the treatment in level one, plus upgrading windows and the insulation levels in walls and ceilings. A level three retrofit involved a total rewrap of the building shell with some of the features in levels one and two incorporated. The demonstration program included the following steps: initial contact with senior citizens; energy audit on each house; determination of level of retrofit work based on individual audit results; contract packages drawn up and put to tender; monitoring of fuel records and air-tightness tests both before and after retrofit; and tabulation of data and information transfer. 10 figs., 4 tabs.

Full Text Available Previous research suggests that creativity training can be effective in academic settings and that teachers in particular can have an impact on creativity. Furthermore, creativity is one of many transferable skills in higher education that will benefit students when they enter the workforce. This study extends research on creativity training and transferable skills in higher education, using data from the Senior Transitions topical module of the National Survey of Student Engagement (NSSE. Responses from over 48,000 seniors at 227 different U.S colleges and universities were used to explore curricular differences across disciplinary fields as well as how exposure to creative coursework can predict confidence in numerous skills and abilities. Exploratory and confirmatory factor analysis provided support for a measure of exposure to creative coursework, and an ANOVA suggested significant differences by major fields, with arts majors showing a distinct advantage. Results from ordinary least squares regression models found that even after controlling for several demographic and institutional characteristics, creative coursework is a significant positive predictor of confidence in several different skills and abilities that are important for adapting to traditional and non-traditional work settings, including creative thinking, critical thinking, entrepreneurial skills, and networking abilities. Potential reasons for these patterns of results are discussed. These findings can help to inform curricular and programming enhancements for college students across all major fields, helping to better prepare them for their futures in various workplace settings.

Jung, Yuchae

2017-05-22

Smart home technology with situation-awareness is important for seniors to improve safety and security. With the development of context-aware computing, wearable sensor technology, and ubiquitous computing, it is easier for seniors to manage their health problem in smart home environment. For monitoring senior activity in smart home, wearable, and motion sensors-such as respiration rate (RR), electrocardiography (ECG), body temperature, and blood pressure (BP)-were used for monitoring movements of seniors. For context-awareness, environmental sensors-such as gas, fire, smoke, dust, temperature, and light sensors-were used for senior location data collection. Based on senior activity, senior health status can be classified into positive and negative. Based on senior location and time, senior safety is classified into safe and emergency. In this paper, we propose a hybrid inspection service middleware for monitoring elderly health risk based on senior activity and location. This hybrid-aware model for the detection of abnormal status of seniors has four steps as follows: (1) data collection from biosensors and environmental sensors; (2) monitoring senior location and time of stay in each location using environmental sensors; (3) monitoring senior activity using biometric data; finally, (4) expectation-maximization based decision-making step recommending proper treatment based on a senior health risk ratio.

Anti-leukemia activity of MS-275 histone deacetylase inhibitor implicates 4-1BBL/4-1BB immunomodulatory functions.

Directory of Open Access Journals (Sweden)

Bérengère Vire

Full Text Available Histone deacetylase inhibitors (HDACi have demonstrated promising therapeutic potential in clinical trials for hematological malignancies. HDACi, such as SAHA/Vorinostat, Trichostatin A, and MS-275 were found to induce apoptosis of leukemic blasts through activation of the death receptor pathway and transcriptional induction of the Tumor Necrosis Factor (TNF-related pro-apoptotic family members, TRAIL and FasL. The impact of HDACi on TNF-related costimulatory molecules such as 4-1BB ligand (4-1BBL/TNFSF9 is however not known. Following exposure to SAHA/Vorinostat, Trichostatin A, and MS-275, transcript levels were determined by real time PCR in Jurkat, Raji and U937 cells. Treatment with HDACi up-regulated TNFSF9 gene expression in the three leukemia cell lines, yet to different extend and with distinct kinetics, which did not require de novo protein synthesis and was not associated with DNAse I hypersensitive chromatin remodeling. Transcriptional activity of TNFSF9 promoter-luciferase constructs was induced up to 12 fold by HDACi, and implication of Sp1/Sp3 transcription factors binding to functional GC-box elements was evidenced by reporter gene assays, site-directed mutagenesis, and electrophoretic mobility shift assays. Functionality of modulated target genes was assessed in allogeneic mixed leukocyte reaction experiments. MS-275- and to a lesser extent Trichostatin A- and SAHA-treated Raji cells significantly up regulated T lymphocytes proliferation which was reduced by about 50% by a 4-1BB blocking recombinant protein, while MS-275- but neither Trichostatin A- nor SAHA-treated cells up-regulated IFNgamma secretion by T lymphocytes. Our results identify 4-1BBL/4-1BB as a downstream target of HDACi, especially of MS-275 anti-leukemia action in vitro. Thus, HDACi such as MS-275 displaying dual TNF-dependent proapoptotic and costimulatory activities might be favored for inclusion in HDACi-based anti-cancer therapeutic strategies.

Alsagheer, Abdullah

This study looks into transfer of learning and its application in the actual employment of engineering students after graduation. At Kuwait University, a capstone course is being offered that aims to ensure that students amalgamate all kinds of engineering skills to apply to their work. Within a basic interpretive, qualitative study-design methodology, I interviewed 12 engineers who have recently experienced the senior design course at Kuwait University and are presently working in industry. From the analysis, four basic themes emerged that further delineate the focus of the entire study. The themes are 1) need for the capstone course, 2) applicability of and problems with the capstone course, 3) industry problems with training, and 4) students' attitudes toward the capstone course. The study concludes that participants are not transferring engineering skills; rather, they are transferring all types of instructions they have been given during their course of study at the university. A frequent statement is that the capstone course should be improved and specifically that it is necessary to improve upon the timing, schedule, teachers' behavior, contents, and format. The study concludes that Kuwaiti engineers on the whole face problems with time management and management support. The study includes some implications for Kuwait University and recommendations that can provide significant support for the development of the Senior Design (Capstone) Course. For examples: the project must be divided into phases to ensure timely completion of deliverables. In order to motivate students for hard work and to achieve true transfer of learning, Kuwait University is required to communicate with certain organizations to place its students at their research centers for capstone projects. All universities, including Kuwait University, should hire faculty specifically to run the capstone course. In conclusion, the study includes some suggestions for further research studies focused

Cascades in multiplex financial networks with debts of different seniority

Science.gov (United States)

Brummitt, Charles D.; Kobayashi, Teruyoshi

2015-06-01

The seniority of debt, which determines the order in which a bankrupt institution repays its debts, is an important and sometimes contentious feature of financial crises, yet its impact on systemwide stability is not well understood. We capture seniority of debt in a multiplex network, a graph of nodes connected by multiple types of edges. Here an edge between banks denotes a debt contract of a certain level of seniority. Next we study cascading default. There exist multiple kinds of bankruptcy, indexed by the highest level of seniority at which a bank cannot repay all its debts. Self-interested banks would prefer that all their loans be made at the most senior level. However, mixing debts of different seniority levels makes the system more stable in that it shrinks the set of network densities for which bankruptcies spread widely. We compute the optimal ratio of senior to junior debts, which we call the optimal seniority ratio, for two uncorrelated Erdős-Rényi networks. If institutions erode their buffer against insolvency, then this optimal seniority ratio rises; in other words, if default thresholds fall, then more loans should be senior. We generalize the analytical results to arbitrarily many levels of seniority and to heavy-tailed degree distributions.

The purpose of this study was to determine the motivation of paid non-familial caregivers of seniors, understand more about their work conditions, and identify any links to negative outcomes among their senior clients. Ninety-eight paid caregivers (eighty-five female and thirteen male), recruited from multiple sites (i.e. senior centers, shopping malls, local parks, lobbies of senior apartments, caregiver agency meetings) completed face-to-face questionnaires and semi-structured interviews. We found that 60.7% of participants chose to become a caregiver because they enjoyed being with seniors while 31.7% were unable to obtain other work, and 8.2% stated it was a prerequisite to a different health related occupation. Caregivers stated that the most challenging conditions of their work were physical lifting (24.5%), behavioral and psychological symptoms of dementia (24.5%), senior depression/mood changes (18.4%), attachment with impending death (8.2%), missing injuries to client (5.1%), lack of sleep (4.1%), and lack of connection with outside world (3.1%). Caregivers who reported that the best part of their job was the salary, flexible hours, and ease of work were significantly more likely to have clients who fell and fractured a bone than those who enjoyed being with seniors (job characteristics, 62.5% vs. senior enjoyment, 25.6%; pmotivated commonly by their love of seniors and also by their lack of other job opportunities. Paid caregivers frequently face challenging work conditions. When seeking a caregiver for a senior, motivation of the caregiver should be considered when hiring.

Full Text Available The purpose of this study was to investigate whether self-concept of EFL teachers influenced their effectiveness in teaching English as a foreign language, as perceived by both teachers and students. The study involved 275 EFL teachers and 88 senior high school students in South Sumatra. Variables of education, teaching experience, and age were analyzed using multiple regression analysis, and specific hypotheses were tested to see whether the addition of the other independent variables could add to the effectiveness of the teacher. The results showed significant relationships between self-concept and all the four factors used to define teacher effectiveness. The combination of self-concept and experience serves as the first salient factor influencing the four factors of teacher effectiveness in addition to self-concept alone. Education was also found to be a factor which influenced teacher effectiveness

Senior research investigating the impact of livestock integration and multi-species cover crop grown within the crop rotation is studying changes in soil attributes resulting from the crop-animal integration by measuring bulk density and in-season soil fertility in the crop rotation. These responses are further contrasted with results from within the crop rotation and responses from perennial native range. Students that become engaged in the research represent a broad cross section of the consuming public and include high school junior and senior students, college undergraduate students that conduct research projects, postdoctoral research scientists engaged in senior level research, agricultural extension educators, and finally, farmer and rancher businessmen. The integrated nature of the research provides a wealth of learning opportunities for these various groups. For the high school students, visits to the living laboratory increase awareness and introduces students to a potential career path in agriculture, natural resource fields, and the many allied vocational fields that support agriculture. When college undergraduate students visit the living laboratory, they seek to address a researchable question or a problem in agriculture, while fulfilling requirements for graduation by conducting a research project. Because postdoctoral students want to be actively engaged in research and advanced learning, they are interested in conducting research in the living laboratory that can be published in peer reviewed journals. Agricultural extension educators, who advise farmers and ranchers, are looking for research results from the living laboratory that can be convey to their constituents. Farmers and ranchers participate in workshop events that give them face-to-face learning opportunities that they can use to effect change in their farm and ranch businesses. Each of these demographic groups are unique in their interest in the

Aging is an inevitable part of life. One can maintain well-being and wellness even after discharge and/or transition if his or her functional decline is minimized, sudden decline is prevented, and functioning is promoted during hospitalization. Caring appropriately for elderly patients requires the systematic application of Senior-Friendly Hospital principles to all operating systems, including medical centres' organization and environment, as well as patient treatment processes. The Senior-Friendly Hospital framework is valid and important for patient safety and quality improvement. This study aimed to make recommendations regarding the development of the Korean Framework for Senior-Friendly Hospitals for older patients' care management, patient safety interventions, and health promotion, via a Delphi survey. Two rounds of Delphi surveying were conducted with 15 participants who had at least 3 years' experience in accreditation surveying and medical accreditation standards, survey methods, and accreditation investigator education. In each round, we calculated statistics describing each standard's validity and feasibility. The Korean Framework for Senior-Friendly Hospitals included 4 Chapters, 11 categories, and 67 standards through consensus of the Senior-Friendly Hospitals task force and experts' peer review. After the two rounds of Delphi surveying, validity evaluation led to no changes in standards of the Senior-Friendly Hospitals; however, the number of standards showing adequate validity decreased from 67 to 58. Regarding feasibility, no changes were necessary in the standards; however, the number of categories showing adequate feasibility decreased from 11 to 8 and from 67 to 30, respectively. The excluded categories were 3.2, 4.2, and 4.3 (service, transportation, and signage and identification). The highest feasibility values were given to standards 2.1.1, 4.1.4, and 4.1.6. The highest feasibility score was given to standard 2.4.2. The Korean Framework for

Full Text Available This research aims to find out the typical categories of answers to Yes/No questions most used by students at selected Public Senior High Schools in Medan, Indonesia. These schools were classified into top favorite, medium favorite and non-favorite schools. Through a stratified clustered random sampling technique, six schools were chosen consisting of two schools from each classification. A number of 40 students were chosen from three class X, three class XI and three class XII at each of the six chosen schools, making a total sample of 720 students with 360 sets of dialogue scripts. Data was collected through documentation-recording dialogues. The data was transcribed and analyzed by descriptive analysis. The results of the research showed that: 1 the categories of the students’ answers to the Yes/No questions were distributed variously in terms of the six models. However, the distribution of the answers was not proportionally equal amongst all the models, 2 the dominant distribution of the answers was the third model with the formula Yes/No+additional information such as confirming, supporting, etc., reaching 37% of the total answers, whilst the least common models were the sixth and fourth categories respectively, which had 1% and 3% of the answers respectively, and finally 3 there was no significant difference in the distribution of the students’ answers in terms of the class of school whether top favorite, medium favorite or non-favorite. In conclusion, the ways to answer Yes/No questions need to be developed amongst students by their teachers by teaching and learning using natural, real life-like situations and in contextual ways.

This is a qualitative research with case study method which aims to gain insight about interpretation, understanding, perceptions and feelings of teenage voters’ behavior in searching and finding information about general election in Indonesia year 2014. The data were collected by conducting interview and observation. Informants in this study were students, aged 17-18 years, who studying in government senior high school in Depok. The results of this study indicates that informants using social media to keep update about general election. Besides, they also gain information from their parents and close friends. Unfortunatelly, they were not able to identify which information which are correct or not, so they rely on people around them to make sure whether they did right decision. Therefore, this study also suggest that KPU needs to develop promotion strategy that suitable for teens about general election.

rate (HR transient at sudden dynamic exercise, through the identification of the cardiac vagal index (CVI obtained from the electrocardiogram (ECG. OBJECTIVE: To evaluate the use of the Polar S810 heart rate monitor (HRM as an alternative resource to the use of the electrocardiogram in the 4-second exercise test. METHODS: In this study, 49 male individuals (25 ± 20 years, 176 ±12 cm, 74 ± 6 kg underwent the 4-second exercise test. The RR intervals were recorded simultaneously by ECG and HRM. We calculated the mean and the standard deviation of the last RR interval of the pre-exercise period, or of the first RR interval of the exercise period, whichever was longer (RRB, of the shortest RR interval of the exercise period (RRC, and of the CVI obtained by ECG and HRM. We used the Student t-test for dependent samples (p < 0.05 to test the significance of the differences between means. To identify the correlation between the ECG and the HRM, we used the linear regression to calculate the Pearson's correlation coefficient and the strategy proposed by Bland and Altman. RESULTS: Linear regression showed r² of 0.9999 for RRB, 0.9997 for RRC, and 0.9996 for CVI. Bland e Altman strategy presented standard deviation of 0.92 ms for RRB, 0.86 ms for RRC, and 0.002 for CVI. CONCLUSION: Polar S810 HRM was more efficient in the application of T4s compared to the ECG.

During the last 18 years, senior citizens in Viborg, Denmark, have participated in study circles based on the theory of impression pedagogy and socially relevant activities. They arrange excursions at home and abroad and make films about the trips. They teach schoolchildren, students at folk high schools, and nurses, as well as occupational therapists and physiotherapists. They publish poems and books, write role plays, stage musicals, sing in choirs, and function as tour guides in town. They set up educational color slide programmes on preventing bone fractures, dealing with the problem of reduced hearing, and the importance of healthy food and exercise. They travel abroad and talk about Denmark and the conditions for senior citizens in our country. With the support of the Danish Ministry for Social Affairs, they produce videos about their activities as a source of inspiration to others. The use of drugs by the participants in the study circles has declined, while the level of activities has increased, and none of the participants has ever had to enter residential care.

The design and measurement results of an 8-bit SAR ADC, based on a charge-redistribution DAC, are presented. This ADC is characterized by superior power efficiency and small area, realized by employing a lateral metal–metal capacitor array and a dynamic two-stage comparator. To avoid the need for a highspeed clock and its associated power consumption, an asynchronous logic was implemented in a logic control cell. A test chip has been developed in a 65 nm CMOS technology, including eight ADC channels with different layout flavors of the capacitor array, a transimpedance amplifier as a signal input structure, a serializer, and a custom-made LVDS driver for data transmission. The integral (INL) and differential (DNL) nonlinearities are measured below 0.5 LSB and 0.8 LSB, respectively, for the best channel operating at a sampling frequency of 10 MS/s. The area occupies 40 μm 70 μm for one ADC channel. The power consumption is estimated as 4 μW at 1 MS/s and 38 μW at 10 MS/s with a supply rail of 1.2 V. Th...

Tris(nonylphenyl)phosphite, an antioxidant used in polyethylene resins for food applications, is problematic since it is a source of the endocrine-disrupting chemicals 4-nonylphenols (4NP) upon migration into packaged foods. As a response to concerns surrounding the presence of 4NP-based compounds in packaging materials, some resin producers and additive suppliers have decided to eliminate TNPP from formulations. This paper describes an analytical procedure to verify the "TNPP-free" statement in multilayer laminates used for bag-in-box packaging. The method involves extraction of TNPP from laminates with organic solvents followed by detection/quantification by LC-MS/MS using the atmospheric pressure chemical ionisation (APCI) mode. A further acidic treatment of the latter extract allows the release of 4NP from potentially extracted TNPP. 4NP is then analysed by LC-MS/MS using electrospray ionisation (ESI) mode. This two-step analytical procedure ensures not only TNPP quantification in laminates, but also allows the flagging of other possible sources of 4NP in such packaging materials, typically as non-intentionally added substances (NIAS). The limits of quantification were 0.50 and 0.48 µg dm⁻² for TNPP and 4NP in laminates, respectively, with recoveries ranging between 87% and 114%. Usage of such analytical methodologies in quality control operations has pointed to a lack of traceability at the packaging supplier level and cross-contamination of extrusion equipment at the converter level, when TNPP-containing laminates are processed on the same machine beforehand.

Sharma, Leena; Regan, Carol; Villers, Katherine S

2018-04-12

Over the past century, the organized voice of seniors has been critical in building the U.S. health safety net. Since the 2016 election, that safety net, particularly the Medicaid program, is in jeopardy. As we have seen with the rise of the Tea Party, senior support for health care programs-even programs that they use in large numbers-cannot and should not be taken for granted. This article provides a brief history of senior advocacy and an overview of the current senior organizing landscape. It also identifies opportunities for building the transformational organizing of low-income seniors needed to defend against sustained attacks on critical programs. Several suggestions are made, drawn from years of work in philanthropy, advocacy, and campaigns, for strengthening the ability to organize seniors-particularly low-income seniors-into an effective political force advocating for Medicaid and other safety net programs.

Among tree nut allergens, pecan allergens remain to be identified and characterized. The objective was to demonstrate the IgE-binding ability of pecan 11S legumin and characterize its sequential IgE-binding epitopes. The 11S legumin gene was amplified from a pecan cDNA library and expressed as a fusion protein in Escherichia coli. The native 11S legumin in pecan extract was identified by mass spectrometry/mass spectrometry (MS/MS). Sequential epitopes were determined by probing the overlapping peptides with three serum pools prepared from different patients' sera. A three-dimensional model was generated using almond legumin as a template and compared with known sequential epitopes on other allergenic tree nut homologues. Of 28 patients tested by dot blot, 16 (57%) bound to 11S legumin, designated Car i 4. MS/MS sequencing of native 11S legumin identified 33 kDa acidic and 20-22 kDa basic subunits. Both pecan and walnut seed protein extracts inhibited IgE binding to recombinant Car i 4, suggesting cross-reactivity with Jug r 4. Sequential epitope mapping results of Car i 4 revealed weak, moderate, and strong reactivity of serum pools against 10, 5, and 4 peptides, respectively. Seven peptides were recognized by all three serum pools, of which two were strongly reactive. The strongly reactive peptides were located in three discrete regions of the Car i 4 acidic subunit sequence (residues 118-132, 208-219, and 238-249). Homology modeling of Car i 4 revealed significant overlapping regions shared in common with other tree nut legumins.

The efficacy of methods like e-learning as a supplement to traditional face-to-face instruction needs to be evaluated in dental courses. This study aimed to assess the efficacy of posting case presentations on one of the educational websites of  the virtual school of Tehran University of Medical Sciences called "SARMAD" to enhance the ability of senior dental students to diagnose tooth discolorations and offer treatment plans. This experimental study had a pre-test/post-test control group design and was conducted on 63 senior dental students. After filling out the primary questionnaire and obtaining a written informed consent, students participated in a pre-test and were then randomly divided into two groups of intervention and control. Fifteen case presentations were posted on the university website (SARMAD) during 6 weeks and discussed. Then, students participated in a post-test. Students' perspectives and their satisfaction with the website were assessed by a questionnaire. For ethical purposes, the same program was also offered to the controls. The post-test score was significantly higher than the pre-test score in the intervention group (P<0.001); but in the control group, the post-test score was only slightly higher than the pre-test score (P=0.128). In the intervention group, 70% stated that they would suggest this method as an efficient educational modality; 93.3% stated that this method would be beneficial as a supplement to conventional education; 16.7% ranked the SARMAD website excellent, 30% ranked it good, 33.3% acceptable, 16.7% moderate and 3.3 poor. It appears that this instructional modality may be efficiently used as a supplement to traditional instruction in undergraduate dental curricula.

Full Text Available The study investigated constructivist practices through guided discovery approach and the effect on students’ cognitive achievement in Nigerian senior secondary school Physics. The study adopted pretest-posttest control group design. A criterion sampling technique was used to select six schools out of nine schools that met the criteria. A total of 278 students took part in the study; this was made up of 141 male students and 137 female students in their respective intact classes. Physic Achievement Test (PAT with the internal consistency of 0.77 using Kuder-Richardson formula (21 was the instrument used in collecting data. The data were analyzed using Analysis of Covariance (ANCOVA and t-test. The results showed that guided discovery approaches was the most effective in facilitating students’ achievement in physics after being taught using a pictorial organizer. This was followed by demonstration while expository was found to be the least effective. Also, there exists no significant difference in the achievement of male and female physics students taught with guided discovery, demonstration and expository teaching approaches and corresponding exposure to a pictorial organizer. It is recommended that physics teachers should endeavor to use constructivist practices through guided discovery approach in order to engage students in problem solving activities, independent learning, critical thinking and understanding, and creative learning, rather than in rote learning and memorization.

2000-05-01

Application of gas chromatography-mass spectrometry (GC-MS) can significantly improve trace analyses of compounds in complex matrices from natural environments compared to gas chromatography only. A GC-MS/MS technique for determination of poly-beta-hydroxybutyrate (PHB), a bacterial storage compound, has been developed and used for analysis of two soils stored for up to 319 d, fresh samples of sewage sludge, as well as a pure culture of Bacillus megaterium. Specific derivatization of beta-hydroxybutyrate (3-OH C4:0) PHB monomer units by N-tert-butyl-dimethylsilyl-N-methyltrifluoracetamide (MTBSTFA) improved chromatographic and mass spectrometric properties of the analyte. The diagnostic fragmentation scheme of the derivates tert-butyldimethylsilyl ester and ether of beta-hydroxybutyric acid (MTBSTFA-HB) essential for the PHB identification was shown. The ion trap MS was used, therefore the scan gave the best sensitivity and with MS/MS the noise decreased, so the S/N was better and also with second fragmentation the amount of ions increased compared to SIM. The detection limit for MTBSTFA-HB by GC-MS/MS was about 10(-13) g microL(-1) of injected volume, while by GC (FID) and GC-MS (scan) it was around 10(-10) g microL(-1) of injected volume. Sensitivity of GC-MS/MS measurements of PHB in arable soil and activated sludge samples was down to 10 pg of PHB g(-1) dry matter. Comparison of MTBSTFA-HB detection in natural soil sample by GC (FID), GC-MS (scan) and by GC-MS/MS demonstrated potentials and limitations of the individual measurement techniques.

This study has been carried out aiming to measure the elderly’s self-esteem dwelling in Ahwaz Nursing Homes in 2014. This is a descriptive-comparative study carried out on 190 people of the seniors dwelling in Ahwaz nursing homes. For the eligible seniors, two questioners of Rosenberg’s Measuring Scale, and Cooper Smith’s Measuring Scale were filled out. The variables regression was determined by using SPSS statistical software, version 18. About 44% of participants in the study were aged from 60 to 65 years old. 68% were men, and 61% were married. Some 50% had 3 to 5 children. More than 43% received higher education. Some 53% were financially dependent. About 50% were self-employed. There was no significant difference between self-esteem among the male and female seniors. Also, there was no significant difference among the elderly’s self-esteem based on their marital status. But, there was a significant negative correlation between the total scores of self-esteem, and the marital status, the financial independence, and dwelling in the nursing homes. As, for the effect of the self-esteem on the elderly’s mental health, and their being highly affected by the life conditions, and with respect to the cultural, religious, and social position of Iran, as much as possible, the backgrounds should be provided for the seniors to dwell with their families; and, if dwelling in the nursing homes is the best choice, providing necessary services with high quality should be employed with grater attempts.

Purpose To determine the social contexts associated with past-year substance use (multiple substances, alcohol, marijuana, and nonmedical use of prescription opioids, stimulants and tranquilizers) among U.S. high school seniors. Methods A secondary analysis of nationally representative survey data from ten cohorts (2002-2011) of the Monitoring the Future study, including 24,809 high school seniors. Results The social contexts associated with past-year substance use varied considerably based on which substance was used. The most prevalent location for alcohol, marijuana, and polydrug use was at a party while nonmedical use of prescription stimulants, tranquilizers and opioids was most likely to occur at home. Most types of substance use occurred in the presence of other people with the exception of nonmedical use of prescription stimulants that was a more solitary behavior. Conclusions These exploratory findings indicate that prevention efforts may need to account for differences in social contexts between types of substances used. PMID:25156895

At-risk high school seniors: Science remediation for Georgia's High School Graduation Test

Science.gov (United States)

Carroll, Carolyn M.

State departments of education have created a system of accountability for the academic achievement of students under the mandate of the No Child Left Behind Act of 2001. The Georgia Department of Education established the Georgia High School Graduation Test (GHSGT) as their method of evaluating the academic achievement of high school students. The GHSGT consist of five sections and students must pass all five sections before students they are eligible to receive a diploma. The purpose of the study was to examine the effects of teacher-lead and computer based remediation for a group of high school seniors who have been unsuccessful in passing the science portion of the GHSGT. The objectives of this study include (a) Identify the most effective method of remediation for at-risk students on the science section of the GHSGT, and (b) evaluate the methods of remediation for at-risk students on the science section of GHSGT available to high school students. The participants of this study were at-risk seniors enrolled in one high school during the 2007-2008 school year. The findings of this research study indicated that at-risk students who participated in both types of remediation, teacher-led and computer-based, scored significantly higher than the computer-based remediation group alone. There was no significant relationship between the test scores and the number of times the students were tested.

Garlic (A. sativum) contains a large number of small sulphur (S)-containing metabolites, which are important for its taste and smell and vary with A. sativum variety and growth conditions. This study was designed to investigate the influence of different sulphur-fertilization regimes on low molecular weight S-species by attempting the first sulphur mass balance in A. sativum roots and bulbs using HPLC-ICPMS/MS-ESI-MS/MS. Species unspecific quantification of acid soluble S-containing metabolites was achieved using HPLC-ICP-MS/MS. For identification of the compounds, high resolution ESI-MS (Orbitrap LTQ and q-TOF) was used. The plants contained up to 54 separated sulphur-containing compounds, which constitute about 80% of the total sulphur present in A. sativum. The roots and bulbs of A. sativum contained the same compounds, but not necessarily the same amounts and proportions. The S-containing metabolites in the roots reacted more sensitively to manipulations of sulphur fertilization than those compounds in the bulbs. In addition to known compounds (e.g. γ-glutamyl-S-1-propenylcysteine) we were able to identify and partially quantify 31 compounds. Three as yet undescribed S-containing compounds were also identified and quantified for the first time. Putative structures were assigned to the oxidised forms of S-1-propenylmercaptoglutathione, S-2-propenylmercaptoglutathione, S-allyl/propenyl-containing PC-2 and 2-amino-3-[(2-carboxypropyl)sulfanyl]propanoic acid. The parallel use of ICP-MS/MS as a sulphur-specific detector and ESI-MS as a molecular detector simplifies the identification and quantification of sulphur containing metabolites without species specific standards. This non-target analysis approach enables a mass balance approach and identifies the occurrence of the so far unidentified organosulphur compounds. The experiments showed that the sulphur-fertilization regime does not influence sulphur-speciation, but the concentration of some S

Results showed that participants held strong beliefs about further mathematics and there was a statistically significant difference in the mean post-treatment scores on BFMQ (t=-6.22, p=.000 for t-test and (F(1,95=38.49; p<.001 for ANOVA between students exposed to the PBL and those exposed to the TM, in favour of the PBL group. Based on the results, the study recommended that PBL should be adopted as an instructional strategy for promoting meaningful learning in and enhancing beliefs about further mathematics and efforts should be made to integrate the philosophy of PBL into the preservice teachers' curriculum at the teacher-preparation institutions in Nigeria.

Joint MS Degree Program between the Korea University of Technology and Education and the University of Kansas

Dougherty, R. L.; Kim, Kwang Su

This paper provides an overview of the Joint MS Degree Program between Korea University of Technology and Education’ s (KUT) Mechatronics Department and Kansas University’ s (KU) Mechanical Engineering Department. Discussions were initiated in early 2005 which resulted in a formal agreement being approved by both parties in mid-2007. The Joint MS Degree Program is composed of 30 semester credit hours, equally split between the two universities, with the actual degree being awarded by the institution at which the thesis work is performed. Issues addressed during the development of this Joint MS Program included: joint versus dual degrees, institutional acceptance of the transfer of fifteen hours of credit for an MS degree, different admissions requirements and procedures for the two institutions, financial support of the students, faculty advisors at each institution, Graduate Directors at each institution, transcript acknowledgement of the Joint Degree, residency requirements, English speaking requirements/abilities, thesis publication allowances/requirements, and time zone differences for virtual meetings. These issues have been addressed, and the Joint MS Degree Program is functioning with a small number of students having taken advantage of the opportunity since the Program’ s inception. Future considerations are: growing the number of students in the Program, expansion to other Departments besides KU-Mechanical Engineering and KUTMechatronics, including other universities in the Program, expansion to a Joint PhD Degree Program, and stronger funding resources.

1S and $\\overline{MS}$ Bottom Quark Masses from $\\Upsilon$ Sum Rules

Hoang, A.H.

2000-01-01

The bottom quark $1S$ mass, $M_b^{1S}$, is determined using sum rules which relate the masses and the electronic decay widths of the $\\Upsilon$ mesons to moments of the vacuum polarization function. The $1S$ mass is defined as half the perturbative mass of a fictitious ${}^3S_1$ bottom-antibottom quark bound state, and is free of the ambiguity of order $\\Lambda_{QCD}$ which plagues the pole mass definition. Compared to an earlier analysis by the same author, which had been carried out in the pole mass scheme, the $1S$ mass scheme leads to a much better behaved perturbative series of the moments, smaller uncertainties in the mass extraction and to a reduced correlation of the mass and the strong coupling. We arrive at $M_b^{1S}=4.71\\pm 0.03$ GeV taking m_b(\\bar m_b)$ can be reduced if the three-loop corrections to the relation of pole and $\\bar{MS}$ mass are known and if the error in the strong coupling is decreased.

We have launched a new intervention study, called "REPRINTS" (Research of productivity by intergenerational sympathy) in which senior volunteers aged 60 years and over engage in reading picture books to school children, regularly visiting public elementary schools since 2004. The purpose of this study was to clarify characteristics of images of older people held by elementary school children and factors associated with such images, as well as to examine changes in images through intervention by "REPRINTS" senior volunteers (volunteers) for the initial one year period. Four to six volunteers as a group visited A elementary school in a suburb Kawasaki city (470 students) twice a week to read picture books. The baseline survey was conducted one month after launching the volunteer activity. First and second follow-up surveys were conducted at 6 month intervals after the baseline survey. Grade, gender, short version of emotional-like image scale of older adults assessed by the SD (Semantic Differential) method (6 items in the subscale for "evaluation" and 4 items in the subscale for "potency/activity"), experience of living with grandparents, experience of interchange with older people, frequency of interchange with volunteers and the social desirability scale for children. Related variables for a higher score in the subscale for "evaluation" included lower grade and abundant experience of interchange with older people such as grandparents. Those for "potency/ activity" included lower grade, male gender, and a higher social desirability scale for children in the multiple logistic regression model. Students were divided into two groups in terms of frequency of interchange with volunteers (low and high-frequency groups) through three surveys. In the subscale for "evaluation", the general linear model demonstrated a significant interaction between the group and number of surveys adjusted for confounding factors. Although emotional images of older people significantly

En este trabajo se analiza el uso que personas mayores activas realizan de Internet, así como los principales beneficios o motivaciones de su utilización, y las barreras que encuentran aquéllos que no la utilizan. Se administró un cuestionario a personas inscritas en programas universitarios de mayores. Los resultados muestran que estos mayores universitarios se conectan a Internet frecuentemente, a diario o entre dos o tres veces por semana. Se destaca la relevancia de Internet para estar actualizados, contactar con la familia y los amigos, el uso académico, y consultar la prensa. La consideran fácil de utilizar aunque afirman que podrían vivir sin ella. Por otro lado, para los que no acceden a Internet no saber utilizarla es una de las principales barreras, si bien las personas que no la utilizan consideran que serían capaces de aprender. En su conjunto los datos animan a romper estereotipos negativos sobre los mayores y a no considerar a los mayores activos como personas incapaces o desconectadas de la Red sino a valorar positivamente los avances que realizan y la motivación por aprender.The Internet is increasingly prominent in all walks of life, and Web connection is a key factor in social integration.

Full Text Available O objetivo deste artigo é analisar a percepção de executivos jovens e seniores sobre as formas de cada um deles lidar com os impactos das mudanças no atual ambiente de negócios. Como objetivos específicos, esta percepção é analisada em relação a: empregabilidade; remuneração variável; perspectiva da carreira; equilíbrio entre a vida pessoal e profissional; preconceitos relativos ao "jovem" e ao "velho". A pesquisa descritiva que originou este trabalho é rara na literatura, tanto em nível de abrangência quanto de profundidade. A opção metodológica recaiu sobre o método misto quantitativo-qualitativo. A pesquisa quantitativa contou com 959 respondentes, 492 jovens (até 40 anos e 467 seniores. A pesquisa qualitativa contou com 263 respondentes em 10 grandes empresas de vários setores da economia. O referencial teórico explora as demandas de uma carreira exigente, onde jovens e seniores enfrentam os desafios da lógica da empregabilidade, e buscam um difícil equilíbrio entre vida pessoal e profissional. Os resultados mostram que os jovens estão chegando mais cedo ao topo da carreira. Isso traz tensões: o sênior teme não conseguir sua recolocação no mercado em alguma eventualidade e se sente ameaçado pelo jovem; o jovem se sente inseguro quanto à sua competência, pressionado pelo aumento substancial de expectativas em relação à sua capacidade. As tensões provocadas pela difícil conciliação do trabalho com a família e pelas restrições às perspectivas de crescimento na carreira devido ao enxugamento das estruturas organizacionais, somam-se àquelas relacionadas a valores de gerações diferentes. Este quadro gera, por um lado, conflitos e preconceitos de parte a parte e, por outro, oportunidades de complementaridade. Os executivos jovens estão ainda mais insatisfeitos que os seniores com: remuneração, sobrecarga de trabalho, nível de estresse, nível de cobrança por resultados e a saúde em geral. A

Smith, Marcus S

2006-01-01

Despite worldwide popularity of amateur boxing, research focussed on the physiological demands of the sport is limited. The physiological profile of Senior and Junior England international amateur boxers is presented. A gradual (8 to 21-days) and rapid (0 to 7-days) phase of body weight reduction was evident with 2.2 ± 0.3 % of the 7.0 ± 0. 8 % weight loss occurring over the final 24-hours. An increase in body weight >4% was observed following a recovery period. High urine osmolality values (> 1000 mOsm·kg(-1)) were recorded during training and competition. High post-competition blood lactate values (>13.5 mmol·l(-1)) highlighted the need for a well-developed anaerobic capacity and the importance of not entering the ring in a glycogen depleted state. The aerobic challenge of competition was demonstrated by maximum heart rate values being recorded during 'Open' sparring. Mean body fat values of 9-10% were similar to those reported for other weight classified athletes. Normal resting values were reported for hematocrit (Senior 48 ± 2 % and Junior 45 ± 2 %), haemoglobin (Senior 14.7 ± 1.0 g·dl(-1) and Junior 14.5 ± 0.8 g·dl(-1)), bilirubin (Senior 15.3 ± 6.2 µmol·l-1(-1)) and ferritin (Senior 63.3 ± 45.7 ng·ml(-1)). No symptoms associated with asthma or exercise-induced asthma was evident. A well- developed aerobic capacity was reflected in the Senior VO2max value of 63.8 ± 4.8 ml·kg(-1)·min(-1). Senior lead hand straight punching force (head 1722 ± 700 N and body 1682 ± 636 N) was lower than the straight rear hand (head 2643 ± 1273 N and body 2646 ± 1083 N), lead hook (head 2412 ± 813 N and body 2414 ± 718 N) and rear hook (head 2588 ± 1040 N and body 2555 ± 926 N). It was concluded that amateur boxing performance is dependent on the interplay between anaerobic and aerobic energy systems. Current weight making methods may lead to impaired substrate availability, leading to reduced competitive performance and an increased risk to a boxers

A simple, specific, sensitive and rapid LC-ESI-MS/MS method has been developed and validated for the quantification of 4-methylpyrazole in dog plasma using N-methylnicotinamide-d 4 as an internal standard (IS) as per regulatory guidelines. Sample preparation was accomplished through a simple protein precipitation. Chromatographic separation of 4-methylpyrazole and the IS was performed on a monolithic (Chromolith RP 18e ) column using an isocratic mobile phase comprising 0.2% formic acid in water and acetonitrile (20:80, v/v) at a flow rate of 1.0 mL/min. Elution of 4-methylpyrazole and the IS occurred at ~1.60 and 1.56 min, respectively. The total chromatographic run time was 3.2 min. A linear response function was established in the concentration range of 4.96-4955 ng/mL. The intra- and inter-day accuracy and precision were in the ranges 1.81-12.9 and 3.80-11.1%, respectively. This novel method has been applied to a pharmacokinetic study in dogs. Copyright © 2017 John Wiley & Sons, Ltd.

Correlation Among Students’ Family Background, Academic Performance in Junior High School, and Senior High School Tracking in Taiwan

Full Text Available There were numerous previous studies on educational tracking. However, most of the data adopted in these studies were collected a decade ago, involving sample population 20-64 years of age. Among them, many elderly samples had undergone senior high school tracking in the early years. The present study used the data of students and parents from the 3rd wave (2005 of the Taiwan Education Panel Survey (TEPS. A path analysis was conducted to investigate the inequality of opportunities involved in the influence of student family background on educational tracking at the senior high school stage. The results show: although the overall percentage of junior high school graduates entering advanced levels was approximately 100% and almost all students of different family backgrounds entered advanced levels, the most crucial factor among those affecting educational tracking of senior high school stage was students’ academic performance during junior high school. Students with higher family socioeconomic status and fewer siblings showed better academic performance in junior high schools, and consequently had higher possibilities of entering public senior high schools leading to a more promising future. This indicates that though the inequality in the quantity of opportunities approached 0, the inequality in the quality of opportunities still remained, which fails to support the hypothesis of the maximally maintained inequality of educational opportunity (MMI; however, the result supports the hypothesis of the effectively maintained inequality of educational opportunity (EMI.

Effective anesthetics are a critical component of safe and humane fish handling procedures. We tested three concentrations each of four anesthetics—Finquel (tricaine methanesulfonate, herein referred to as MS-222), BENZOAK (20% benzocaine), AQUI-S 20E (10% eugenol), and Aquacalm (metomidate hydrochloride)—for efficacy and safety in metamorphosed, outmigrating juvenile Pacific Lampreys Entosphenus tridentatus. The anesthetics MS-222 (100 mg/L) and BENZOAK (60 mg/L) were the most effective for anesthetizing juvenile Pacific Lampreys to a handleable state with minimal irritation to the fish. Fish anesthetized with BENZOAK also had lower rates of fungal infection than those exposed to MS-222, AQUI-S 20E, or no anesthetic. Exposure to AQUI-S 20E irritated juvenile Pacific Lampreys, causing them to leap or climb out of the anesthetic solution, and Aquacalm anesthetized fish to a handleable state too slowly and incompletely for effective use with routine handling procedures. Our results indicate that MS-222 and BENZOAK are effective anesthetics for juvenile Pacific Lampreys, but field studies are needed to determine whether exposure to MS-222 increases risk of fungal infection in juvenile Pacific Lampreys released to the wild.

Full Text Available Abstract Objectives To examine work satisfaction, quality of life, and leisure time of neonatology fellows and senior neonatologists in Israel. Methods A validated questionnaire was delivered during the second half of 2008 to all the neonatology fellows and senior neonatologists in Israel. Descriptive analysis, parametric Student’s t-test, and aparametric Mann Whitney and χ2 tests were conducted. Results Of 114 practicing neonatologists in that period in Israel (including both seniors and fellows, 112 (98.25% participated in the study. The majority of neonatologists were male (53.2%, married (91.7%, 40–60 years old (69.7%, and studied in Israeli medical schools (62.0%. Most did their pediatric residencies and fellowships in Israel (97.2% and 75.7%, respectively. The average number of night/on-call shifts of fellows and senior neonatologists was 8.8 per month (SD ± 3.425 and the number of active on-call shifts was 4.04 (SD ± 3.194. The satisfaction level of neonatologists in Israeli medical centers with patient care, self-reward, work relations, and quality of life was high, but their satisfaction level with workload, income and prestige, and leisure time was low. The general index of work satisfaction and the general index of indices were both high in relation to the mid-range values. The majority of neonatologists stated that they would choose to practice medicine again. Most of them would encourage medical students to choose the same specialty they had chosen. Only a few neonatologists were contemplating changing their choice of specialty. Most neonatologists want to continue practicing medicine; however, a significant number will not recommend that their children do so. Conclusions The satisfaction level of neonatologists in Israel is high, mainly due to satisfaction with their work. High satisfaction levels promise high quality patient care, as well as high satisfaction levels of patients and their families. However

An in silico MS/MS library for automatic annotation of novel FAHFA lipids.

2015-01-01

A new lipid class named 'fatty acid esters of hydroxyl fatty acids' (FAHFA) was recently discovered in mammalian adipose tissue and in blood plasma and some FAHFAs were found to be associated with type 2 diabetes. To facilitate the automatic annotation of FAHFAs in biological specimens, a tandem mass spectra (MS/MS) library is needed. Due to the limitation of the commercial available standard compounds, we proposed building an in silico MS/MS library to extend the coverage of molecules. We developed a computer-generated library with 3267 tandem mass spectra (MS/MS) for 1089 FAHFA species. FAHFA spectra were generated based on authentic standards with negative mode electrospray ionization and 10, 20, and 40 V collision induced dissociation at 4 spectra/s as used in in ultra-high performance liquid chromatography-QTOF mass spectrometry studies. However, positional information of the hydroxyl group is only obtained either at lower QTOF spectra acquisition rates of 1 spectrum/s or at the MS(3) level in ion trap instruments. Therefore, an additional set of 4290 fragment-rich MS/MS spectra was created to enable distinguishing positional FAHFA isomers. The library was generated based on ion fragmentations and ion intensities of FAHFA external reference standards, developing a heuristic model for fragmentation rules and extending these rules to large swaths of computer-generated structures of FAHFAs with varying chain lengths, degrees of unsaturation and hydroxyl group positions. Subsequently, we validated the new in silico library by discovering several new FAHFA species in egg yolk, showing that this library enables high-throughput screening of FAHFA lipids in various biological matrices. The developed library and templates are freely available for commercial or noncommercial use at http://fiehnlab.ucdavis.edu/staff/yanma/fahfa-lipid-library. This in silico MS/MS library allows users to annotate FAHFAs from accurate mass tandem mass spectra in an easy and fast manner
