    In academia, women remain underrepresented. The authors' sought to examine differences in faculty position and professional satisfaction among academic physicians by gender. From 2008 to 2012, academic faculty members at a single institution were surveyed (2008, n = 737; 2010, n = 1151; and 2012, n = 971) regarding current position, choice of position, professional satisfaction, and desire for leaving. Logistic regression was performed to compare aspects of professional satisfaction by gender. Men more often held tenure track positions compared with women (2008, 45 percent versus 20 percent; 2010, 47 percent versus 20 percent; and 2012, 49 percent versus 20 percent; p Women were more likely to engage in only clinical activities compared with men (2008, 31 percent versus 18 percent; 2010, 28 percent versus 14 percent; and 2012, 33 percent versus 13 percent; p Women chose tracks to accommodate work-life balance [2008, OR, 1.9 (95 percent CI, 1.29 to 2.76); 2010, OR, 2.0 (95 percent CI, 1.38 to 2.76); and 2012, OR, 2.1 (95 percent CI, 1.40 to 3.00)], rather than the opportunity of tenure [2008, OR, 0.4 (95 percent CI, 0.23 to 0.75); 2010, OR, 0.5 (95 percent CI, 0.35 to 0.85); and 2012, OR, 0.5 (95 percent CI, 0.29 to 0.76) compared with men. Men reported higher professional satisfaction compared with women (2008, 5.7 versus 5.4, p women. Women report lower levels of professional satisfaction in academic practice compared with men. Given the increasing pressures of academic practice, efforts to align work-life balance and professional goals could potentially improve faculty satisfaction and retention.

  11. Alternative models for academic family practices

    Directory of Open Access Journals (Sweden)

    2006-03-01

    Full Text Available Abstract Background The Future of Family Medicine Report calls for a fundamental redesign of the American family physician workplace. At the same time, academic family practices are under economic pressure. Most family medicine departments do not have self-supporting practices, but seek support from specialty colleagues or hospital practice plans. Alternative models for academic family practices that are economically viable and consistent with the principles of family medicine are needed. This article presents several "experiments" to address these challenges. Methods The basis of comparison is a traditional academic family medicine center. Apart of the faculty practice plan, our center consistently operated at a deficit despite high productivity. A number of different practice types and alternative models of service delivery were therefore developed and tested. They ranged from a multi-specialty office arrangement, to a community clinic operated as part of a federally-qualified health center, to a team of providers based in and providing care for residents of an elderly public housing project. Financial comparisons using consistent accounting across models are provided. Results Academic family practices can, at least in some settings, operate without subsidy while providing continuity of care to a broad segment of the community. The prerequisites are that the clinicians must see patients efficiently, and be able to bill appropriately for their payer mix. Conclusion Experimenting within academic practice structure and organization is worthwhile, and can result in economically viable alternatives to traditional models.

    LaDuke, Rebekah D

    2013-01-01

    The purpose of this article was to review the most current published literature on the topics of academic dishonesty, unethical professional practices, and research that studied the correlation between these 2 areas of interest. Literature was retrieved by utilizing key words such as academic dishonesty, cheating, workplace dishonesty, and unethical behavior. Multiple research databases were used and a reference librarian in locating relevant research studies resulting in 16 research articles reviewed and 7 articles referenced within the literature review. Upon completion, it became apparent that nursing educators should be concerned that nursing students found to be academically dishonest today may have a higher incidence of displaying unethical practices as a registered nurse tomorrow. It also became clear that the nursing profession needs to conduct its own research in this field to verify findings discovered by other professions such as engineering, business, and psychology. Finally, recommendations were given on how nursing educators should handle the topic of ethics in nursing programs. Copyright © 2013 Elsevier Inc. All rights reserved.

  15. Improving coding accuracy in an academic practice.

    2017-01-01

    Practice management has become an increasingly important component of graduate medical education. This applies to every practice environment; private, academic, and military. One of the most critical aspects of practice management is documentation and coding for physician services, as they directly affect the financial success of any practice. Our quality improvement project aimed to implement a new and innovative method for teaching billing and coding in a longitudinal fashion in a family medicine residency. We hypothesized that implementation of a new teaching strategy would increase coding accuracy rates among residents and faculty. Design: single group, pretest-posttest. military family medicine residency clinic. Study populations: 7 faculty physicians and 18 resident physicians participated as learners in the project. Educational intervention: monthly structured coding learning sessions in the academic curriculum that involved learner-presented cases, small group case review, and large group discussion. overall coding accuracy (compliance) percentage and coding accuracy per year group for the subjects that were able to participate longitudinally. Statistical tests used: average coding accuracy for population; paired t test to assess improvement between 2 intervention periods, both aggregate and by year group. Overall coding accuracy rates remained stable over the course of time regardless of the modality of the educational intervention. A paired t test was conducted to compare coding accuracy rates at baseline (mean (M)=26.4%, SD=10%) to accuracy rates after all educational interventions were complete (M=26.8%, SD=12%); t24=-0.127, P=.90. Didactic teaching and small group discussion sessions did not improve overall coding accuracy in a residency practice. Future interventions could focus on educating providers at the individual level.

  17. Inbreeding, energy use and condition.

    2009-04-01

    In energetic terms, fitness may be seen to be dependent on successful allocation of energy between life-history traits. In addition, fitness will be constrained by the energy allocation ability, which has also been defined as condition. We suggest here that the allocation ability, estimated as the difference between total energy budget and maintenance metabolism, may be used as a measure of condition. We studied this possibility by measuring the resting metabolic rate and metabolism during forced exercise in Gryllodes sigillatus crickets. To verify that these metabolic traits are closely related to fitness, we experimentally manipulated the degree of inbreeding of individuals belonging to the same pedigree, hence enabling analysis of both inbreeding depression and heritability of traits. We found that inbreeding increased maintenance metabolism, whereas total energy budget was rather insensitive to inbreeding. Despite this, inbreeding led to decreased allocation ability. Overall, metabolic traits exhibited strong inbreeding depression and rather low heritabilities, a pattern that is typical of traits under strong selection. However, traditionally used condition indices were not affected by inbreeding and did not covary with metabolic traits. Moreover, in contrast to the common, but largely untested, tenet, it seems that high resting metabolic rate is indicative of low rather than high quality.

    Extra-pair reproduction is widely hypothesized to allow females to avoid inbreeding with related socially paired males. Consequently, numerous field studies have tested the key predictions that extra-pair offspring are less inbred than females' alternative within-pair offspring, and that the probability of extra-pair reproduction increases with a female's relatedness to her socially paired male. However, such studies rarely measure inbreeding or relatedness sufficiently precisely to detect subtle effects, or consider biases stemming from failure to observe inbred offspring that die during early development. Analyses of multigenerational song sparrow (Melospiza melodia) pedigree data showed that most females had opportunity to increase or decrease the coefficient of inbreeding of their offspring through extra-pair reproduction with neighboring males. In practice, observed extra-pair offspring had lower inbreeding coefficients than females' within-pair offspring on average, while the probability of extra-pair reproduction increased substantially with the coefficient of kinship between a female and her socially paired male. However, simulations showed that such effects could simply reflect bias stemming from inbreeding depression in early offspring survival. The null hypothesis that extra-pair reproduction is random with respect to kinship therefore cannot be definitively rejected in song sparrows, and existing general evidence that females avoid inbreeding through extra-pair reproduction requires reevaluation given such biases. © 2014 The Author(s).

    A special challenge has been presented to academic medical practices by the new healthcare environment. While increased competition for patients and resources affects all medical groups, it is the academic practices who are responsible for training the physicians of tomorrow. Not only must they sharpen their students' awareness of the new environment and teach them to incorporate effective management strategies into their practices, but they must set an example in effective management as well. The basic concepts of competitive marketing strategy, along with helpful exhibits, are presented here, and strategies for effectively maximizing position are discussed from the viewpoints of product mix, process market, and financing.

  14. Best Practices in Academic Mentoring: A Model for Excellence

    Directory of Open Access Journals (Sweden)

    Jan M. Nick

    2012-01-01

    Full Text Available Mentoring is important for the recruitment and retention of qualified nurse faculty, their ongoing career development, and leadership development. However, what are current best practices of mentoring? The purpose of this paper is to provide an overview of a model for excellence in establishing a formal mentoring program for academic nurse educators. Six themes for establishing a formal mentoring program are presented, highlighting best practices in mentoring as culled from experience and the literature. Themes reflect aims to achieve appropriately matched dyads, establish clear mentorship purpose and goals, solidify the dyad relationship, advocate for and guide the protégé, integrate the protégé into the academic culture, and mobilize institutional resources for mentoring support. Attending to the six themes will help mentors achieve important protégé outcomes, such as orientation to the educator role, integration into the academic community, development of teaching, scholarship, and service skills, as well as leadership development. The model is intended to be generalizable for faculty teaching in a variety of academic nursing institution types and sizes. Mentoring that integrates the six themes assists faculty members to better navigate the academic environment and more easily transition to new roles and responsibilities.

    From Harvard to high school, concern related to academic misconduct, specifically cheating and its impact on societal issues, has become a great concern for educational communities. While a significant number of studies on ethical behaviors in practice in other professions such as business have been published, little research exists on registered nurses in practice. Even fewer studies have, for registered nurses, addressed if there is an association between perceived academic misconduct as students and perceived unethical behaviors in the workplace. The purpose of this study was to determine the relationship between perceptions of registered professional nurses' (RNs) current workplace behaviors and the RNs' retrospective perceptions of their academic misconduct as students. A convenience sample of 1 66 RNs enrolled in master's degree programs at four university schools of nursing completed questionnaires regarding their beliefs and behaviors. The outcome of this study was significant. Results revealed a strong relationship between unethical behaviors of the RN in practice and their prior academic misconduct when they were students.

    This article describes an academic-practice partnership between an American Nurses Credentialing Center Magnet ® -designated hospital and an academic nurse educator that has increased the hospital's capacity for research, evidence-based practice, and support for nurses continuing their education. Through close collaboration with the full-time nurse researcher and members of the nursing education department, the professor in residence consults with clinical staff to support completion of research and evidence-based practice projects. The collaboration also has resulted in the development of a formal year-long mentoring program for clinical nurses in the area of evidence-based practice. Individual support and academic consults are offered to nurses enrolled in school to promote advancement of nurses' educational level. This collaboration has been beneficial for both the hospital and the university, increasing the capacity for scholarly activities for nurses in the hospital and serving as a forum for ongoing faculty practice and scholarship.

    Williams, Tracy E; Howard, Patricia B

    2017-12-01

    The aims of this article were to describe the implementation of an academic-practice partnership for healthcare system workforce development and provide preliminary outcomes of the associated pilot study. The demand for cross-continuum healthcare delivery models necessitates creation of workforce development structures for advanced practice nursing. An academic-practice partnership specified enrollment of 5 cohorts of BSN staff nurses in a 3-year DNP program. Qualitative methods were used to explore pilot data at midpoint of cohort 1 student progression to determine learning outcomes and DNP projects with potential for impact on organization goals. Partnership implementation experiences indicate that contractual agreements and an established evaluation plan are keys to academic-practice partnership success. Pilot study findings suggest that curriculum core courses provide a foundation for designing DNP projects congruent with acute and primary care health system goals. Implementing an academic-practice partnership is a strategy for workforce development to increase retention of advanced practice nurses. Academic-practice partnerships can serve as a catalyst for a paradigm shift for changing models of care, thus enhancing workforce development succession planning for sustainable growth in healthcare systems.

    Pedigree information of 852,443 registered Holstein cows and bulls, collected by the Animal Breeding Center of Iran from 1971 to 2007, was used to calculate inbreeding coefficients and their effect on production, reproduction, somatic cell count, calving ease, and longevity traits. The average...... reproductive traits, the observed undesirable effect of inbreeding was not significant, except for the calving interval (0.53 d per 1% increase in inbreeding) in the third parity and age at first calving (0.45 d per 1% increase in inbreeding). Calving ease in heifers and cows was significantly influenced...... by the inbreeding of the dam, indicating that highly inbred cows had a higher incidence of difficult calvings. The estimate of inbreeding depression for somatic cell score was low and significant only for the third lactation. However, animals with high inbreeding coefficient tended to have higher somatic cell...

    In this article, there is a discussion focused on three contemporary nursing topics: leadership, followership, and academic-practice partnerships. These comments are framed within the context of the current healthcare system transformation. There is a focus on why each of these topics is relevant to the nursing profession in leading change and advancing health. Finally, there is a description about the interdependence of leadership and followership and the significance these hold for the interdependence between nursing education and nursing practice. © The Author(s) 2016.

  5. Scientific literacy and academic identity: Creating a community of practice

    Reveles, John Michael

    2005-07-01

    This one-year ethnographic study of a third grade classroom examined the construction of elementary school science. The research focused on the co-development of scientific literacy and academic identity. Unlike much research in science education that views literacy as merely supportive of science; this dissertation research considers how students learned both disciplinary knowledge in science as well as about themselves as learners through language use. The study documented and analyzed how students came to engage with scientific knowledge and the impact this engagement had upon their academic identities over time. Ethnographic and discourse analytic methods were employed to investigate three research questions: (a) How were the students in a third grade classroom afforded opportunities to acquire scientific literate practices through the spoken/written discourse and science activities? (b) In what ways did students develop and maintain academic identities taken-up over time as they discursively appropriated scientific literate practices via classroom discourse? and (c) How did students collectively and individually inscribe their academic identities and scientific knowledge into classroom artifacts across the school year? Through multiple forms of analyses, I identified how students' communication and participation in science investigations provided opportunities for them to learn specific scientific literate practices. The findings of this empirical research indicate that students' communication and participation in science influenced the ways they perceived themselves as active participants within the classroom community. More specifically, students were observed to appropriate particular discourse practices introduced by the teacher to frame scientific disciplinary knowledge and investigations. Thus, emerging academic identities and developing literate practices were documented via analysis of discursive (spoken, written, and enacted) classroom interactions. A

  6. An Academic-Practice Partnership to Advance DNP Education and Practice.

    Science.gov (United States)

    Howard, Patricia B; Williams, Tracy E

    During the past decade, the growth of doctor of nursing practice (DNP) programs in the United States has been phenomenal, with most focusing on the preparation of advanced practice registered nurses. Simultaneously, academic-practice partnerships have been a frequent subject of discussion for nursing's leading academic, administrative, and practice organizations. Numerous reports about academic-practice partnerships concerning aspects of baccalaureate nursing education exist, but partnership accounts for DNP programs are essentially nonexistent. The purpose of this article is to describe the initial phase of an academic-practice partnership between a multisystem health care organization and a college of nursing in a public land-grant university in the southeastern United States. The 7-year partnership agreement between Norton Healthcare and the University of Kentucky College of Nursing was designed to prepare 5 cohorts of 20 to 30 baccalaureate-prepared staff nurses as DNP graduates for advanced practice registered nurse eligibility. The description of partnering institution characteristics frames an emphasis on elements of the partnership proposal, contractual agreement, and partner responsibilities along with the logic model evaluation plan. Lessons learned include the importance of proposals and contracts to sustain the partnership, frequent communication to build trust, and strategic analysis for rapid response to challenging situations.

    Full Text Available This article proposes and tests a set of performance indicators for the assessment of Bachelor and Master studies, from two perspectives: the study programs and the disciplines. The academic performance at the level of a study program shall be calculated based on success and efficiency rates, and at discipline level, on the basis of rates of efficiency, success and absenteeism. This research proposes a model of classification of the study programs within a Bachelor and Master cycle based on the education performance and efficiency. What recommends this model as a best practice model in academic management is the possibility of grouping a study program or a discipline in a particular category of efficiency

  9. Radiation protection code of practice in academic and research institutes

    The main aim of this study was to establish a code of practice on radiation protection for safe control of radiation sources used in academic and research institutes, another aim of this study was to assess the current situation of radiation protection in some of the academic and research institutes.To achieve the aims of this study, a draft of a code of practice has been developed which is based on international and local relevant recommendation. The developed code includes the following main issues: regulatory responsibilities, radiation protection program and design of radiation installations. The second aim had been accomplished by conducting inspection visits to five (A, B, C, D and E) academic and to four (F, G, H and I ) research institutes. Eight of such institutes are located in Khartoum State and the ninth one is in Madani city (Aljazeera State). The inspection activities have been carried out using a standard inspection check list developed by the regulatory authority of the Sudan. The inspection missions to the above mentioned institutes involved also evaluation of radiation levels around the premises and storage areas of radiation sources. The dose rate measurement around radiation sources locations were found to be quite low. This mainly is due to the fact that the activities of most radionuclides that are used in these institutes are quite low ( in the range of micro curies). Also ,most the x-ray machines that were found in use for scientific academic and research purposes work at low k Vp of maximum 60 k Vp. None of the radiation workers in the inspected institutes has a personal radiation monitoring device, therefor staff dose levels have not been assessed. However it was noted that in most of the academic/ research studies radiation workers are only exposed to very low levels of radiation and for a very short time that dose not exceed 1 minute, therefore the expected occupational exposure of the staff is very low.

    Identifying factors that impact progression of surgery trainees into academic versus non-academic practices may permit tailoring residency experiences to promote academic careers in institutions charged with the training of future surgeon scientists. The aim of this study was to identify factors associated with progression of surgery trainees into academic versus non-academic practice. A survey was distributed to 135 surgeons graduating from the University of Virginia residency program from 1964-2016, a single academic institution. Questions addressed practice type, research productivity, work/life balance, mentorship, and overall sentiment toward research and academic surgery. A 5-point Likert scale measured career satisfaction and influence of factors in practice setting choice. Of the 135 surveys that were electronically distributed, 69 participants responded (response rate: 51%). Of the 54 with known current practice types, 34 (63%) were academic and 20 (37%) non-academic. Academic surgeons reported more publications by the conclusion of surgery training (56% vs 25% with >10 publications, P = .02). More academic surgeons reported >$100,000 in student debt at graduation (44% vs 25%, P productive research experiences, current surgical trainees may be more enthusiastic about a career in academic practice.

Theresearcher aimed to gain insights on the relevance of the current EBLIP model topractice, and to understand the possible connections between scientific researchand tacit knowledge within the practice of LIS.Methods – A grounded theory methodology was used, following the approach ofCharmaz (2006. Participants were 19 academic librarians in Canada. Data wasgathered via online diaries and semi-structured interviews over a six-month periodin 2011.Results – Two broad types of evidence were identified (hard and soft, and aregenerally used in conjunction with one another. Librarians examine all evidencesources with a critical eye, and try to determine a complete picture before reachinga conclusion. As well, librarians use a variety of proactive and passive approachesto find evidence.Conclusions – These results provide a strong message that no single evidencesource is perfect. Consequently, librarians bring different types of evidencetogether in order to be as informed as possible before making a decision. Using acombination of evidence sources, depending upon the problem, is the wayacademic librarians approach decision making.

    2016-01-01

    Full Text Available This work reflects the results from a study on institutional behavior and interaction between teachers and pupils that influence the overall academic performance of postgraduate students from an agronomic institution in Mexico, Postgraduated College (CP. The goal was to identify multiple practices, forms and behaviors where gender is perceived in such way that harassment or mistreat occurs in the form of inequalities expressed in postgraduate programs that have been, traditionally, of a higher masculine presence. The method of investigation used quantitative and qualitative tools; a poll was made through electronic devices aimed at both men and women students from 4 of the 7 campuses. These campuses are spread through several states of Mexico and form part of the Postgraduate College. The students identified behavior that is deemed sexist and/or discriminatory such as psychological abuse at school, use of sexist and non-inclusive language, undermining the academic work of female peers, exclusion, and subordination. All of the stated activities have strong repercussions on school performance, the perception of achievement, emotional stability and self- esteem of the alumni. What we see here is an urgent need to change the way the student body and the professors behave on the institution grounds. It is of essence to analyze gender inequality, from chain of command to the social and symbolic aspects of the postgraduate community. This means restructuring institutional culture, by proposing strategies that veer in favor of equity.

    Clinical pharmacy has a rich history of advancing practice through innovation. These innovations helped to mold clinical pharmacy into a patient-centered discipline recognized for its contributions to improving medication therapy outcomes. However, innovations in clinical pharmacy practice have now waned. In our view, the growth of academic–practice partnerships could reverse this trend and stimulate innovation among the next generation of pioneering clinical pharmacists. Although collaboration facilitates innovation,academic institutions and health care systems/organizations are not taking full advantage of this opportunity. The academic–practice partnership can be optimized by making both partners accountable for the desired outcomes of their collaboration, fostering symbiotic relationships that promote value-added clinical pharmacy services and emphasizing continuous quality improvement in the delivery of these services. Optimizing academic–practice collaboration on a broader scale requires both partners to adopt a culture that provides for dedicated time to pursue innovation, establishes mechanisms to incubate ideas, recognizes where motivation and vision align, and supports the purpose of the partnership. With appropriate leadership and support, a shift in current professional education and training practices, and a commitment to cultivate future innovators, the academic–practice partnership can develop new and innovative practice advancements that will improve patient outcomes.

  1. On the expected relationship between inbreeding, fitness, and extinction

    Directory of Open Access Journals (Sweden)

    Couvet Denis

    2006-06-01

    Full Text Available Abstract We assessed the expected relationship between the level and the cost of inbreeding, measured either in terms of fitness, inbreeding depression or probability of extinction. First, we show that the assumption of frequent, slightly deleterious mutations do agree with observations and experiments, on the contrary to the assumption of few, moderately deleterious mutations. For the same inbreeding coefficient, populations can greatly differ in fitness according to the following: (i population size; larger populations show higher fitness (ii the history of population size; in a population that recovers after a bottleneck, higher inbreeding can lead to higher fitness and (iii population demography; population growth rate and carrying capacity determine the relationship between inbreeding and extinction. With regards to the relationship between inbreeding depression and inbreeding coefficient, the population size that minimizes inbreeding depression depends on the level of inbreeding: inbreeding depression can even decrease when population size increases. It is therefore clear that to infer the costs of inbreeding, one must know both the history of inbreeding (e.g. past bottlenecks and population demography.

    2015-09-01

    Health care has changed over the past decade; yet, nursing education has not kept pace with social and scientific advances. The Institute of Medicine report, The Future of Nursing: Leading Change, Advancing Health, called for a more highly educated nursing work-force and an improved nursing education system. Since the release of that report, the Future of Nursing: Campaign for Action, supported by the Robert Wood Johnson Foundation, AARP, and the AARP Foundation, has worked with nursing education leaders to better understand existing and evolving nursing education structures. Through a consensus-building process, four overarching promising practice models, with an emphasis on seamless academic progression, emerged to advance the goals of education transformation. Key nurse educators and other stakeholders refined those models through a series of meetings, collaborative partnerships, and focused projects that were held across the United States. This article summarizes that process and provides a description of the models, challenges, common themes, recommendations, and progress to date. Copyright 2015, SLACK Incorporated.

    2013-01-01

    The goal of this study was to examine the roles of Physician Assistants (PAs) and Nurse Practitioners (NPs) in pediatric academic otolaryngology programs to provide a better understanding of their scope of practice, levels of autonomy, clinical duties, teaching opportunities and research participation. An anonymous web-based electronic survey tool was sent to all pediatric otolaryngology fellowship program directors in the United States. Nurse Practitioners and Physician Assistants are utilized in approximately 3 out of every 4 pediatric otolaryngology practices. The top three job activities of both the PA and NP were: (1) seeing patients independently, (2) working alongside doctors in clinic, and (3) answering phone lines/parental calls. A higher percentage of PAs (83%), worked alongside doctors in clinic, as compared to NPs, where only 55% work alongside MDs. Over half of PAs round with the in-patient team and see consults as compared to just over one third of NPs who participate in such activities. Twenty-five percent of practices reported that PAs cover call and assist in the OR. Most PAs/NPs saw between 11 and 15 patients per clinic which provides a clear productivity advantage when looking to screen patients, provide medical care, generate surgical cases, and maximize billings. NPs and PAs have complimentary skill sets ideal for the pediatric otolaryngology workplace, although job activities and "best fit" are hospital and practice dependent. Our study suggests that the use of PAs and NPs will continue to grow to meet increased demand for services in the field of pediatric otolaryngology. Employing advanced practice providers enables academic centers to improve access, provide additional financial remuneration, reduce wait times for new patients, and allow attending physicians to meet increased practice demands.

    When qualifying for higher academic positions junior academics face increasing demands for submitting papers for publication. The criteria for assessing these publications are presently under discussion. Contributions to international English language journals are more highly regarded, and it has become indispensable to have papers published in journals listed in SCI and SSCI. The question remains whether these criteria are valid to judge academic qualifications. Whereas one criterion for validity may be the publication practice of the present academic representatives, it appears that to some extent the chairs themselves would not fulfill the requirements for academic qualification today. Results regarding this are presented and discussed.

    2010-09-01

    Full Text Available This article presents some results of an investigation aimed to characterize the academic literacy practices that are developed in the Phonoaudiology program at the University of Cauca. In this descriptive study, a sample of 24 students was taken from those in the last semester of the first academic period of 2009, who answered a survey of 26 multiple choice questions. The results indicate that the academic moment for which the students write and read the most is for the courses, who develop these practices primarily to be assessed and predominantly read and write their own lecture notes and the materials prepared by their faculty, to the detriment of scientific articles or papers for publication. It is expected, from these results, to generate reflexion processes and actions that qualify the practices of academic literacy within the program for the benefit of academic and professional performance of their students and graduates.

  11. Prostate Brachytherapy Case Volumes by Academic and Nonacademic Practices: Implications for Future Residency Training

    2016-01-01

    Purpose: The use of prostate brachytherapy has continued to decline in the United States. We examined the national practice patterns of both academic and nonacademic practices performing prostate brachytherapy by case volume per year to further characterize the decline and postulate the effect this trend might have on training the next generation of residents. Methods and Materials: Men diagnosed with prostate cancer who had undergone radiation therapy in 2004 to 2012 were identified. The annual brachytherapy case volume at each facility was determined and further categorized into ≤12 cases per year (ie, an average of ≤1 cases per month), 13 to 52 cases per year, and ≥53 cases per year (ie, an average of ≥1 cases per week) in academic practices versus nonacademic practices. Results: In 2004 to 2012, academic practices performing an average of ≤1 brachytherapy cases per month increased from 56.4% to 73.7%. In nonacademic practices, this percentage increased from 60.2% to 77.4% (P<.0001 for both). Practices performing an average of ≥1 cases per week decreased among both academic practices (from 6.7% to 1.5%) and nonacademic practices (from 4.5% to 2.7%). Conclusions: Both academic and nonacademic radiation oncology practices have demonstrated a significant reduction in the use of prostate brachytherapy from 2004 to 2012. With the case volume continuing to decline, it is unclear whether we are prepared to train the next generation of residents in this critical modality.

    Full Text Available Inbreeding depression is an important evolutionary factor, particularly when new habitats are colonized by few individuals. Then, inbreeding depression by drift could favour the establishment of later immigrants because their hybrid offspring would enjoy higher fitness. Rotifers are the only major zooplanktonic group where information on inbreeding depression is still critically scarce, despite the fact that in cyclical parthenogenetic rotifers males are haploid and could purge deleterious recessive alleles, thereby decreasing inbreeding depression.We studied the effects of inbreeding in two populations of the cyclical parthenogenetic rotifer Brachionus plicatilis. For each population, we compared both the parental fertilization proportion and F1 fitness components from intraclonal (selfed and interclonal (outcrossed crosses. The parental fertilization proportion was similar for both types of crosses, suggesting that there is no mechanism to avoid selfing. In the F1 generation of both populations, we found evidence of inbreeding depression for the fitness components associated with asexual reproduction; whereas inbreeding depression was only found for one of the two sexual reproduction fitness components measured.Our results show that rotifers, like other major zooplanktonic groups, can be affected by inbreeding depression in different stages of their life cycle. These results suggest that haplodiploidy does not purge efficiently deleterious recessive alleles. The inbreeding depression detected here has important implications when a rotifer population is founded and intraclonal crossing is likely to occur.

    Cardiovascular services are the third largest source of Medicare spending. We examined the rate of cardiovascular service utilization in the community of Glendale, CA, compared with the nearest academic medical center, the University of Southern California. Publicly available utilization data released by Medicare for the years 2012 and 2013 were used to identify all inpatient and outpatient cardiology services provided in each practice setting. The analysis included 19 private and 17 academic cardiologists. In unadjusted analysis, academic physicians performed half as many services per Medicare beneficiary per year as those in private practice: 2.3 versus 4.8, p cardiology practice settings in southern California, medical service utilization per Medicare beneficiary was nearly 2-fold higher in private practice than in the academic setting, suggesting that there may be opportunity for substantially reducing costs of cardiology care in the community setting.

    Understanding how the intensity of inbreeding depression is influenced by stressful environmental conditions is an important area of enquiry in various fields of biology. In birds, environmental stress during early development is often related to hatching asynchrony; differences in age, and thus size, impose a gradient in conditions ranging from benign (first hatched chick) to harsh (last hatched chick). Here, we compared the effect of hatching order on growth rate in inbred (parents are full siblings) and outbred (parents are unrelated) canary chicks (Serinus canaria). We found that inbreeding depression was more severe under more stressful conditions, being most evident in later hatched chicks. Thus, consideration of inbreeding-environment interactions is of vital importance for our understanding of the biological significance of inbreeding depression and hatching asynchrony. The latter is particularly relevant given that hatching asynchrony is a widespread phenomenon, occurring in many bird species. The exact causes of the observed inbreeding-environment interaction are as yet unknown, but may be related to a decrease in maternal investment in egg contents with laying position (i.e. prehatching environment), or to performance of the chicks during sibling competition and/or their resilience to food shortage (i.e. posthatching environment). © 2015 The Author(s).

    Full Text Available A study was carried out on the captive tigers of Nandankanan zoo, Odisha, India, to conclude any deleterious effect of inbreeding on mortality. A pedigree path analysis of 342 tigers was done to estimate the inbreeding coefficient of each tiger from the available pedigree information since the inception of zoological park in 1964. Percentage of animal with different range of inbreeding coefficient was classified based on their normal and white body coat colour. The correlation values between sex, colour and inbreeding coefficient with mortality were also estimated. The colour and inbreeding coefficient was found to be significantly (p<0.05 correlated with the mortality. The inbreeding was found to be significant (p<0.05 with white colour of tiger.

    Physicians' spiritual and religious identities, beliefs, and practices are beginning to be explored. The objective of this study was to gather descriptive information about personal religion and spirituality from a random sample of academic American pediatricians and to compare this information with similar data from the public. In 2005, a Web-based survey of a random sample of 208 pediatrician faculty from 13 academic centers ranked by the US News & World Report as "honor roll" hospitals was conducted. Surveys elicited information about personal beliefs and practices as well as their influence on decisions about patient care and clinical practice. Multiple questions were replicated from the General Social Survey to enable comparisons with the public. Descriptive statistics were generated, and logistic regression analyses were conducted on relevant variables. Nearly 88% of respondents were raised in a religious tradition, but just 67.2% claimed current religious identification. More than half (52.6%) reported praying privately; additional spiritual practices reported included relaxation techniques (38.8%), meditation (29.3%), sacred readings (26.7%), and yoga (19%). The majority of academic pediatricians (58.6%) believed that personal spiritual or religious beliefs influenced their interactions with patients/colleagues. These odds increased 5.1-fold when academic pediatricians attended religious services monthly or more (P religious identity. The majority believed spiritual and religious beliefs influenced their practice of pediatrics. Whether secular or faith-based belief systems measurably modify academic pediatric practice is unknown.

  3. Is faculty practice valuable? The experience of Western Australian nursing and midwifery academics undertaking faculty clinical practice - A discussion paper.

    Fowler, Amanda C; Baker, Melanie; Geraghty, Sadie

    2017-09-01

    The faculty clinical practice model provides dedicated time for nursing lecturers and educators in a university school of nursing to work with supervision in the clinical environments for an agreed amount of time each year. Allowing academics to partake in faculty clinical practice this way has been shown to update skills and retain clinical competency. Some nursing and midwifery academics believe it is essential to remain clinically current and up-to-date with professional issues in the clinical environments, whereas other academics believe reading current research maintains clinical competency. This discussion paper will explore the authors' own experiences of faculty clinical practice as an opportunity to enhance their learning. Narrative accounts of time spent in the clinical areas being expressed as invaluable as it allowed the authors to become part of the health professional team, refine clinical skills, gain clinical confidence, and share knowledge. This, in turn, impacted upon the academic's teaching style as well as redefined it by introducing incidents and stories from their experience. It has been concluded by the authors that faculty clinical practice allows academics to increase confidence, encourage leadership skills, and improve their teaching abilities in their clinical area of expertise.

  4. Feed-backs among inbreeding, inbreeding depression in sperm traits, and sperm competition can drive evolution of costly polyandry.

    Bocedi, Greta; Reid, Jane M

    2017-12-01

    Ongoing ambitions are to understand the evolution of costly polyandry and its consequences for species ecology and evolution. Emerging patterns could stem from feed-back dynamics between the evolving mating system and its genetic environment, defined by interactions among kin including inbreeding. However, such feed-backs are rarely considered in nonselfing systems. We use a genetically explicit model to demonstrate a mechanism by which inbreeding depression can select for polyandry to mitigate the negative consequences of mating with inbred males, rather than to avoid inbreeding, and to elucidate underlying feed-backs. Specifically, given inbreeding depression in sperm traits, costly polyandry evolved to ensure female fertility, without requiring explicit inbreeding avoidance. Resulting sperm competition caused evolution of sperm traits and further mitigated the negative effect of inbreeding depression on female fertility. The evolving mating system fed back to decrease population-wide homozygosity, and hence inbreeding. However, the net overall decrease was small due to compound effects on the variances in sex-specific reproductive success and paternity skew. Purging of deleterious mutations did not eliminate inbreeding depression in sperm traits or hence selection for polyandry. Overall, our model illustrates that polyandry evolution, both directly and through sperm competition, might facilitate evolutionary rescue for populations experiencing sudden increases in inbreeding. © 2017 The Author(s).

    Physician job satisfaction has been the subject of much research. However, no studies have been conducted comparing academic and private practice physician satisfaction in obstetrics and gynecology. This study was undertaken to measure satisfaction levels for academic and private practice obstetrician-gynecologists and compare different aspects of their practice that contributed to their satisfaction. A survey was mailed to randomly selected obstetrician-gynecologists in Memphis, TN; Birmingham, AL; Little Rock, AR; and Jackson, MS. Physicians were asked to respond to questions concerning demographics and career satisfaction. They were also asked to assess the contribution of 13 different aspects of their practice in contributing to their job selection and satisfaction using a Likert scale. A score of 1 meant the physician completely disagreed with a statement regarding a factor's contribution or was completely dissatisfied; a score of 5 meant the physician completely agreed with a factor's contribution or was completely satisfied. Simple descriptive statistics, as well as the 2-sample t test, were used. Likert scale values were assumed to be interval measurements. Of the 297 questionnaires mailed, 129 (43%) physicians responded. Ninety-five (74%) respondents rated their overall satisfaction as 4 or 5. No significant difference was found between academic and private physicians when comparing overall job satisfaction (P = .25). When compared to private practice physicians, the aspects most likely contributing to overall job satisfaction for academic physicians were the ability to teach, conduct research, and practice variety (P = .0001, P = .0001, and P = .007, respectively). When compared with academic physicians, the aspects most likely contributing to job satisfaction for private practice physicians were autonomy, physician-patient relationship, and insurance reimbursement (P = .0058, P = .0001, and P = .0098, respectively).

    To obtain in-depth insight into the perceptions of nurse academics and other stakeholders regarding the importance, facilitators and barriers for nurses combining clinical and academic work in university hospitals. Combining clinical practice and academic work facilitates the use of research findings for high-quality patient care. However, nurse academics move away from the bedside because clinical academic careers for nurses have not yet been established in the Netherlands. This qualitative study was conducted in two Dutch university hospitals and their affiliated medical faculties and universities of applied sciences. Data were collected between May 2015 and August 2016. We used purposive sampling for 24 interviews. We asked 14 participants in two focus groups for their perceptions of importance, facilitators and barriers in nurses' combined clinical and academic work in education and research. We audiotaped, transcribed and thematically analysed the interviews and focus groups. Three themes related to perceived importance, facilitators and barriers: culture, leadership and infrastructure. These themes represent deficiencies in facilitating clinical academic careers for nurses. The current nursing culture emphasises direct patient care, which is perceived as an academic misfit. Leadership is lacking at all levels, resulting in the underuse of nurse academics and the absence of supporting structures for nurses who combine clinical and academic work. The present nursing culture appears to be the root cause of the dearth of academic positions and established clinical academic posts. A culture change would require a show of leadership that would promote and enable combined research, teaching and clinical practice and that would introduce clinical academic career pathways for nurses. Meanwhile, nurse academics should collaborate with established medical academics for whom combined roles are mainstream, and they should take advantage of their established infrastructure

    Inbreeding depression reflects the negative consequences of increased homozygosity at genes that affect fitness. We investigate inbreeding depression in a semi-free-ranging colony of mandrills (Mandrillus sphinx), using high-quality pedigree data, comprising five maternal generations and 20 years of morphological and demographic data. We examine the relationship between inbreeding coefficients and four fitness correlates: two growth parameters (mass and height for age) and longevity in both sexes, and age at first conception in females. Inbreeding was correlated with both growth parameters, but only in females, with inbred females being smaller than noninbred females. Inbreeding was also correlated significantly with age at first conception, with inbred females giving birth earlier in life than noninbred females. We suggest that sex-biased maternal investment may explain this sex-differential response to inbreeding, although the lack of a significant association between inbreeding and growth in males may also be due to the provisioned nature of the colony. The surprising relationship between age at first conception and inbreeding may be related to smaller adult size in inbred females, or to their being less able to escape from male sexual coercion.

    When relatives mate, their inbred offspring often suffer a reduction in fitness-related traits known as "inbreeding depression." There is mounting evidence that inbreeding depression can be exacerbated by environmental stresses such as starvation, predation, parasitism, and competition. Parental care may play an important role as a buffer against inbreeding depression in the offspring by alleviating these environmental stresses. Here, we examine the effect of parental care on the fitness costs of inbreeding in the burying beetle Nicrophorus vespilloides, an insect with facultative parental care. We used a 2 × 2 factorial design with the following factors: (i) the presence or absence of a caring female parent during larval development and (ii) inbred or outbred offspring. We examined the joint influence of maternal care and inbreeding status on fitness-related offspring traits to test the hypothesis that maternal care improves the performance of inbred offspring more than that of outbred offspring. Indeed, the female's presence led to a higher increase in larval survival in inbred than in outbred broods. Receiving care at the larval stage also increased the lifespan of inbred but not outbred adults, suggesting that the beneficial buffering effects of maternal care can persist long after the offspring have become independent. Our results show that parental care has the potential to moderate the severity of inbreeding depression, which in turn may favor inbreeding tolerance and influence the evolution of mating systems and other inbreeding-avoidance mechanisms.

  17. Genomic dissection of inbreeding depression: a gate to new opportunities

    Directory of Open Access Journals (Sweden)

    Ino Curik

    Full Text Available ABSTRACT Inbreeding depression, reduction in performance of quantitative traits, including reproduction and survival, caused by inbreeding, is a well-known phenomenon observed in almost all experimental, domesticated, and natural populations. In spite of its importance to the fate of a small population and numerous research performed in the last century, the genetic basis of inbreeding depression is still unclear. Recent fast development of molecular techniques has enabled estimation of a genomic inbreeding coefficient (FROH, which reflects realized autozygosity and can be further partitioned to chromosomes and chromosomal segments. In this review, we first describe classical approach used in the estimation of inbreeding in livestock populations, followed by early concepts of replacing pedigree inbreeding coefficient by individual heterozygosity. Then, we explain runs of homozygosity as key approach in estimating realized autozygosity. Furthermore, we present two different concepts of analysing regions that substantially contribute to the inbreeding depression. Thus, we describe how to identify or map mutations that result in the reduction of performance and, in terms of quantitative genetics, how to analyse the architecture of inbreeding depression. At the end, we discuss future perspectives in eliminating deleterious mutations from livestock populations.

    Animals have evolved strategies to optimally balance costs and benefits of inbreeding. In social species, these adaptations can have a considerable impact on the structure, the organization, and the functioning of groups. Here, we consider how selection for inbreeding avoidance fashions the social behavior of arthropods, a phylum exhibiting an unparalleled richness of social lifestyles. We first examine life histories and parental investment patterns determining whether individuals should actively avoid or prefer inbreeding. Next, we illustrate the diversity of inbreeding avoidance mechanisms in arthropods, from the dispersal of individuals to the rejection of kin during mate choice and the production of unisexual broods by females. Then, we address the particular case of haplodiploid insects. Finally, we discuss how inbreeding may drive and shape the evolution of arthropods societies along two theoretical pathways.

    Public health clinical educators and practicing public health nurses (PHNs) are experiencing challenges in creating meaningful clinical learning experiences for nursing students due to an increase in nursing programs and greater workload responsibilities for both nursing faculty and PHNs. The Henry Street Consortium (HSC), a collaborative group of PHNs and nursing faculty, conducted a project to identify best practices for public health nursing student clinical learning experiences. Project leaders surveyed HSC members about preferences for teaching-learning strategies, facilitated development of resources and tools to guide learning, organized faculty/PHN pilot teams to test resources and tools with students, and evaluated the pilot team experiences through two focus groups. The analysis of the outcomes of the partnership engagement project led to the development of the Partnership Engagement Model (PEM), which may be used by nursing faculty and their public health practice partners to guide building relationships and sustainable partnerships for educating nursing students. © 2017 Wiley Periodicals, Inc.

    2009-01-01

    Background Inbreeding depression is an important evolutionary factor, particularly when new habitats are colonized by few individuals. Then, inbreeding depression by drift could favour the establishment of later immigrants because their hybrid offspring would enjoy higher fitness. Rotifers are the only major zooplanktonic group where information on inbreeding depression is still critically scarce, despite the fact that in cyclical parthenogenetic rotifers males are haploid and could purge deleterious recessive alleles, thereby decreasing inbreeding depression. Methodology/Principal Findings We studied the effects of inbreeding in two populations of the cyclical parthenogenetic rotifer Brachionus plicatilis. For each population, we compared both the parental fertilization proportion and F1 fitness components from intraclonal (selfed) and interclonal (outcrossed) crosses. The parental fertilization proportion was similar for both types of crosses, suggesting that there is no mechanism to avoid selfing. In the F1 generation of both populations, we found evidence of inbreeding depression for the fitness components associated with asexual reproduction; whereas inbreeding depression was only found for one of the two sexual reproduction fitness components measured. Conclusions/Significance Our results show that rotifers, like other major zooplanktonic groups, can be affected by inbreeding depression in different stages of their life cycle. These results suggest that haplodiploidy does not purge efficiently deleterious recessive alleles. The inbreeding depression detected here has important implications when a rotifer population is founded and intraclonal crossing is likely to occur. Thus, during the foundation of new populations inbreeding depression may provide opportunities for new immigrants, increasing gene flow between populations, and affecting genetic differentiation.

    2013-08-01

    The European royal dynasties of the Early Modern Age provide a useful framework for human inbreeding research. In this article, consanguineous marriage, inbreeding depression and the purging of deleterious alleles within a consanguineous population are investigated in the Habsburgs, a royal dynasty with a long history of consanguinity over generations. Genealogical information from a number of historical sources was used to compute kinship and inbreeding coefficients for the Habsburgs. The marriages contracted by the Habsburgs from 1450 to 1750 presented an extremely high mean kinship (0.0628±0.009), which was the result of the matrimonial policy conducted by the dynasty to establish political alliances through marriage. A strong inbreeding depression for both infant and child survival was detected in the progeny of 71 Habsburg marriages in the period 1450-1800. The inbreeding load for child survival experienced a pronounced decrease from 3.98±0.87 in the period 1450-1600 to 0.93±0.62 in the period 1600-1800, but temporal changes in the inbreeding depression for infant survival were not detected. Such a reduction of inbreeding depression for child survival in a relatively small number of generations could be caused by elimination of deleterious alleles of a large effect according with predictions from purging models. The differential purging of the infant and child inbreeding loads suggest that the genetic basis of inbreeding depression was probably very different for infant and child survival in the Habsburg lineage. Our findings provide empirical support that human inbreeding depression for some fitness components might be purged by selection within consanguineous populations.

    College students at university have to face several stress factors. Although sports practice has been considered as having beneficial effects upon stress and general health, few studies have documented its influence on this specific population. The aim of this comparative study was to determine whether the intensity of the college students' sports practice (categorized into three groups: rare, regular, or intensive) would influence their levels of stress and self-efficacy, their coping strategies, and their academic success/failure. Three self-completion questionnaires were administered to 1071 French freshmen during their compulsory medical visit at the preventive medicine service of the university. Results indicated that students with intensive sport practice reported lower scores of general stress, academic stress, and emotion-focused coping strategies, and higher scores of self-efficacy than those with rare practice. However, the proportion of successful students did not differ significantly between the three groups of sports practice.

    We report social media (SoMe) utilization trends at an academic radiology department, highlighting differences between trainees and faculty and between Baby Boomers versus Generation X and Millennials. An anonymous online survey regarding SoMe utilization and SoMe-based educational curriculum was distributed to all radiologists (trainees and faculty) in our department. Regular chi-square, ordered (Mantel-Haenszel) chi-square, and Fischer exact tests were performed. The survey instrument was sent to 172 radiologists with a 65% completion rate (N = 112). Eighty-three percent (n = 92) of the respondents use SoMe, with Facebook (67%, n = 75), YouTube (57%, n = 64), Instagram (26%, n = 29), and Twitter (21%, n = 23) as the most commonly used platforms. Eighty-one percent (n = 91) use SoMe for 30 minutes or less per day. Thirty-five percent (n = 39) reported previously using SoMe for educational purposes, although 66% (n = 73) would be willing to join SoMe for educational activities. The faculty are more likely than trainees to avoid using SoMe (30% vs 9%, P < 0.03). Trainees are more likely than faculty to find an electronic case-based curriculum valuable (95% vs 83%, P < 0.05) and are willing to spend more time on cases (P < 0.01). Baby Boomers are less interested in joining SoMe for educational activities than Generation X and Millennials (24% vs 73%, P = 0.0001). Generation gaps between trainees and faculty, as well as between Generation X and Millennials versus Baby Boomers, exist with regard to the use of SoMe, which may be underutilized in radiology education.

    2013-04-01

    Full Text Available Tutors are generally considered to be an additional resource in teaching and learning, as a means of augmenting that of the lecturer. This article explores tutors as academic staff with responsibilities for developing practice competencies and integrating student learning in a social care professional training degree programme. The research is small-scale, based upon data from a purposive sample of five interviews; and upon insider-participant observation notes and reflections in one single setting. The author deployed a situated ethnographic methodology alongside a frame analytic approach. The research found that in their academic practice, tutors reveal how their student contact is oriented to developing a reflective practitioner and they discuss how programme inputs impact on the student’s professional self. Simultaneously, tutors seek to create cross programme integration through finding overlaps with academic programme strands.

    Full Text Available The transition to university is a difficult process for many students, having a negative impact on their academic performance, ultimately resulting in failure or withdrawal from one or more courses in their first semester. This practice report describes a profile analysis and readiness assessment designed to identify students at high academic risk. Students so identified were offered additional workshops to address assumed knowledge and academic skills. Attendance at the workshops correlated with improved academic outcomes.

    Responsiveness to citizens as users of technological innovation helps motivate translational research and commercial engagement among academics. Yet, retaining citizen trust and support for research encourages caution in pursuit of commercial science. We explore citizen expectations of the specifically academic nature of commercial science [i.e. academic entrepreneurship (AE)] and the influence of conflict of interest concerns, hopes about practical benefits and general beliefs. We conducted a cross-sectional national opinion survey of 1002 Canadians online in 2010. Approval of AE was moderate (mean 3.2/5, SD 0.84), but varied by entrepreneurial activity. Concern about conflict of interests (COI) was moderate (mean 2.9/5, SD 0.86) and varied by type of concern. An ordinary least-squares regression showed that expectations of practical benefits informed support for AE, specifically that academic-industry collaboration can better address real-world problems; conflict of interest concerns were insignificant. These findings suggest that citizens support AE for its potential to produce practical benefits, but enthusiasm varies and is reduced for activities that may prioritize private over public interests. Further, support exists despite concern about COI, perhaps due to trust in the academic research context. For user engagement in research priority setting, these findings suggest the need to attend to the commercial nature of translational science. For research policy, they suggest the need for governance arrangements for responsible innovation, which can sustain public trust in academic research, and realize the practical benefits that inform public support for AE. © 2014 John Wiley & Sons Ltd.

    2013-01-01

    This survey looks closely at the data curation practices of a sample of research-oriented universities largely from the USA, the UK, Australia and Scandinavia but also including India, South Africa and other countries. The study looks at how major universities are assisting faculty in developing data curation and management plans for large scale data projects, largely in the sciences and social sciences, often as pre-conditions for major grants. The report looks at which departments of universities are shouldering the data curation burden, the personnel involved in the efforts, the costs involved, types of software used, difficulties in procuring scientific experiment logs and other hard to obtain information, types of training offered to faculty, and other issues in large scale data management.

  1. Developing professional identity in nursing academics: the role of communities of practice.

    2009-08-01

    This paper analyses the current standing of nursing within the wider United Kingdom (UK) higher education (HE) environment and considers the development of academic identity within the sector, introducing a technology mediated approach to professional learning and development. A community of practice (CoP) is a way of learning based on collaboration among peers. Individuals come together virtually or physically, with a common purpose, defined by knowledge rather than task [Wenger, E., 1998. Communities of Practice: Learning, Meaning and Identity, sixth ed. Cambridge University Press, Cambridge]. In 2008, a small team of academics at Glasgow Caledonian University, School of Nursing, Midwifery and Community Health created and implemented iCoP, a project undertaken to pilot an international CoP, where novices and expert academics collaborated to debate and discuss the complex transition from clinician to academic. Although not intended as a conventional research project, the developmental journey and emerging online discussion provide an insight into the collective thoughts and opinions of a multi-national group of novice academics. The article also highlights the key challenges, problems and limitations of working in an international online arena with professionals who traditionally work and thrive in a face to face, real time environment.

  2. Evidence of inbreeding depression on human height.

    Directory of Open Access Journals (Sweden)

    Ruth McQuillan

    Full Text Available Stature is a classical and highly heritable complex trait, with 80%-90% of variation explained by genetic factors. In recent years, genome-wide association studies (GWAS have successfully identified many common additive variants influencing human height; however, little attention has been given to the potential role of recessive genetic effects. Here, we investigated genome-wide recessive effects by an analysis of inbreeding depression on adult height in over 35,000 people from 21 different population samples. We found a highly significant inverse association between height and genome-wide homozygosity, equivalent to a height reduction of up to 3 cm in the offspring of first cousins compared with the offspring of unrelated individuals, an effect which remained after controlling for the effects of socio-economic status, an important confounder (χ(2 = 83.89, df = 1; p = 5.2 × 10(-20. There was, however, a high degree of heterogeneity among populations: whereas the direction of the effect was consistent across most population samples, the effect size differed significantly among populations. It is likely that this reflects true biological heterogeneity: whether or not an effect can be observed will depend on both the variance in homozygosity in the population and the chance inheritance of individual recessive genotypes. These results predict that multiple, rare, recessive variants influence human height. Although this exploratory work focuses on height alone, the methodology developed is generally applicable to heritable quantitative traits (QT, paving the way for an investigation into inbreeding effects, and therefore genetic architecture, on a range of QT of biomedical importance.

    Malik, Gulzar; McKenna, Lisa; Griffiths, Debra

    2017-09-01

    This paper is drawn from a grounded theory study that aimed to investigate processes undertaken by academics when integrating evidence-based practice into undergraduate curricula. This paper focuses on how nurse academics facilitated students to apply evidence-based practice in theory and practice. Facilitating undergraduate nursing students to develop skills within an evidence-based practice framework is vital to achieving evidence-based care. Studies on evidence-based practice conducted globally suggests that there is a need to investigate approaches used by nurse academics in facilitating students' understanding and use of evidence-based practice during their nurse education. Employing constructivist grounded theory approach, 23 nurse academics across Australian universities were interviewed and nine observed during their teaching. Some study participants shared their unit guides to enrich analysis. Data analysis was performed by following Charmaz's approach of coding procedures; as a result, four categories were constructed. This paper focuses on the category conceptualised as Envisaging the use of evidence-based practice. Findings revealed that most academics-assisted students to use evidence in academic-related activities. Recognising the importance of evidence-based practice in practice, some also expected students to apply evidence-based practice during clinical experiences. However, the level of students' appreciation for evidence-based practice during clinical experiences was unknown to participants and was influenced by practice-related barriers. Acknowledging these challenges, academics were engaged in dialogue with students and suggested the need for academia-practice collaboration in combating the cited barriers. Ensuring academics are supported to emphasise clinical application of evidence-based practice requires strategies at school and practice levels. Faculty development, engagement of clinical nurses with evidence-based practice, supportive

    In the United States, minimum standards for quality control (QC) are specified in federal law under the Clinical Laboratory Improvement Amendment and its revisions. Beyond meeting this required standard, laboratories have flexibility to determine their overall QC program. We surveyed chemistry and immunochemistry QC procedures at 21 clinical laboratories within leading academic medical centers to assess if standardized QC practices exist for chemistry and immunochemistry testing. We observed significant variation and unexpected similarities in practice across laboratories, including QC frequency, cutoffs, number of levels analyzed, and other features. This variation in practice indicates an opportunity exists to establish an evidence-based approach to QC that can be generalized across institutions.

    Full Text Available This practice report details an institutional innovation designed to enhance academic capacities for curriculum development, with a particular focus on the first year experience (FYE. The authors discuss the appointment of “Curriculum Scholars” in each of the faculties at James Cook University. This innovation can be seen as an example of third generation responses to the challenges of the first year in higher education (FYHE (Kift, Nelson & Clarke, 2010. The report  discusses the question of academic identity and the tension between a discipline-specific identity and identification with the scholarship of teaching and learning. The authors argue that this tension may have significant implications for the success of third generation approaches to the FYE. This tension is the focus of a multi-method research project being developed by the authors. The autoethnographical dimension of this project is described, inviting participants to reflect on their own journeys as academics engaged in learning and teaching.

    Quality measures are used to standardize health care and monitor quality of care. In 2011, the American Gastroenterological Association established quality measures for inflammatory bowel disease (IBD), but there has been limited documentation of compliance from different practice settings. We reviewed charts from 367 consecutive patients with IBD seen at academic practices, 217 patients seen at community practices, and 199 patients seen at private practices for compliance with 8 outpatient measures. Records were assessed for IBD history, medications, comorbidities, and hospitalizations. We also determined the number of patient visits to gastroenterologists in the past year, whether patients had a primary care physician at the same institution, and whether they were seen by a specialist in IBD or in conjunction with a trainee, and reviewed physician demographics. A univariate and multivariate statistical analysis was performed to determine which factors were associated with compliance of all core measures. Screening for tobacco abuse was the most frequently assessed core measure (89.6% of patients; n = 701 of 783), followed by location of IBD (80.3%; n = 629 of 783), and assessment for corticosteroid-sparing therapy (70.8%; n = 275 of 388). The least-frequently evaluated measures were pneumococcal immunization (16.7% of patients; n = 131 of 783), bone loss (25%; n = 126 of 505), and influenza immunization (28.7%; n = 225 of 783). Only 5.8% of patients (46 of 783) had all applicable core measures documented (24 in academic practice, none in clinical practice, and 22 in private practice). In the multivariate model, year of graduation from fellowship (odds ratio [OR], 2.184; 95% confidence interval [CI], 1.522-3.134; P measures. We found poor documentation of IBD quality measures in academic, clinical, and private gastroenterology practices. Interventions are necessary to improve reporting of quality measures.

    Inbreeding and relatedness in wild panda populations are important parameters for panda conservation. Habitat loss and fragmentation are expected to increase inbreeding but the actual inbreeding levels in natural panda habitats were unknown. Using 150,025 SNPs and 14,926 SNPs selected from published whole-genome sequences, we estimated genomic inbreeding coefficients and relatedness of 49 pandas including 34 wild pandas sampled from six habitats. Qinling and Liangshan pandas had the highest levels of inbreeding and relatedness measured by genomic inbreeding and coancestry coefficients, whereas the inbreeding levels in Qionglai and Minshan were 28-45% of those in Qinling and Liangshan. Genomic coancestry coefficients between pandas from different habitats showed that panda populations from the four largest habitats, Minshan, Qionglai, Qinling and Liangshan, were genetically unrelated. Pandas between these four habitats on average shared 66.0-69.1% common alleles and 45.6-48.6% common genotypes, whereas pandas within each habitat shared 71.8-77.0% common alleles and 51.7-60.4% common genotypes. Pandas in the smaller populations of Qinling and Liangshan were more similarly to each other than pandas in the larger populations of Qionglai and Minshan according to three genomic similarity measures. Panda genetic differentiation between these habitats was positively related to their geographical distances. Most pandas separated by 200 kilometers or more shared no common ancestral alleles. The results provided a genomic quantification of the actual levels of inbreeding and relatedness among pandas in their natural habitats, provided genomic confirmation of the relationship between genetic diversity and geographical distances, and provided genomic evidence to the urgency of habitat protection.

    Full Text Available Objective: To assess academic emergency medicine (EM chairs’ perceptions of quality improvement (QI training programs.Methods: A voluntary anonymous 20 item survey was distributed to a sample of academic chairs of EM through the Association of Academic Chairs of Emergency Medicine. Data was collected to assess the percentage of academic emergency physicians who had received QI training, the type of training they received, their perception of the impact of this training on behavior, practice and outcomes, and any perceived barriers to implementing QI programs in the emergency department.Results: The response rate to the survey was 69% (N = 59. 59.3% of respondents report that their hospital has a formal QI program for physicians. Chairs received training in a variety of QI programs. The type of QI program used by respondents was perceived as having no impact on goals achieved by QI (χ2 = 12.382; p = 0.260, but there was a statistically significant (χ2 = 14.383; p = 0.006 relationship between whether or not goals were achieved and academic EM chairs’ perceptions about return on investment for QI training. Only 22% of chairs responded that they have already made changes as a result of the QI training. 78.8% of EM chairs responded that quality programs could have a significant positive impact on their practice and the healthcare industry. Chairs perceived that QI programs had the most potential value in the areas of understanding and reducing medical errors and improving patient flow and throughput. Other areas of potential value of QI include improving specific clinical indicators and standardizing physician care.Conclusion: Academic EM chairs perceived that QI programs were an effective way to drive needed improvements. The results suggest that there is a high level of interest in QI but a low level of adoption of training and implementation.[West J Emerg Med. 2010; 11(5:479-485.

    Full Text Available The buffalo is a native animal of Iran and there were 500,000 buffaloes in Iran that over 80 per cent of its population concentrated in the north and north- west (Azerbaijan province and 18 per cent in the south (Khuzestan province of the country. Buffaloes reread in rural condition as multi purpose animals in Khuzestan. For mating, farmer use owns herd sire also artificial insemination is limited in the rural condition that may be inbred animals so affect the production performance. The aim of this investigation was estimate the inbreeding coefficient and its affect on some production performance. Data of 200 herds were used from the record sheets of herds under recording program of Animal Breeding Center during period 1990 to 2002 in the Khuzestan province. These results showed mostly herds only one sir and rarely two sires have been used. Inbreeding coefficient was 25 percent in some progeny and high-inbred buffaloes had a low performance. According to results of this study it could be concluded that farmers to avoid inbreeding should use other herd sire and artificial insemination also practical recording scheme and genetically selection to genetic improvement should be included in buffaloes of Iran.

    2013-01-01

    Full Text Available Background. Collaborative nursing research across academic and practice settings is imperative to generate knowledge to improve patient care. Models of academic/practice partnerships for nursing research are lacking. This paper reports data collected before and during a one-day retreat for nurse researchers and administrators from local universities and health care organizations designed to establish a regional nursing research partnership. Methods. Quantitative and qualitative methods were used to address the study aims: (1 to assess research involvement and institutional research resources; (2 to assess interest in and concerns regarding cross-institutional collaborations; and (3 to describe perceptions of the purpose of a partnership and resources needed to ensure success. Results. Participants (n=49 had differing perceptions of accessibility to resources; participants in practice settings reported less accessibility to resources, notably grant development, informatics, and research assistant support. Participants were interested in collaboration although concerns about conflict of interest were expressed. Four themes related to partnering were identified: harnessing our nursing voice and identity; developing as researchers; staying connected; and positioning for a collaborative project. Conclusion. Academic-practice research collaborations will become increasingly important with health care system changes. Strategies to develop and sustain productive partnerships should be supported.

  14. Culturally Diverse Students in Higher Education: Challenges and Possibilities within Academic Literacy Practices

    Elena Tkachenko

    2016-10-01

    Full Text Available With growing diversity in the population, higher education faces a new situation with increasing student diversity. In our paper, we will explore questions concerning the consequences student diversity has for higher-education institutions. Based on our experience from three different R&D projects, the differences in culture and academic literacy practices give culturally diverse students challenges that have often been ignored in academia. Some other studies also document that this group of students has a much higher risk of dropping out and underachieving than majority students (Andersen & Skaarer- Kreutz, 2007; Støren, 2009. In our paper, we are going to discuss the students’ challenges and discourse of remediation that is often associated with their challenges and suggest how higher-education institutions can adjust their practices to be more oriented to intercultural communication. Intercultural communication as a dialogic approach may create dynamics in academic tutoring and lead to mutual change/transformation instead of a one-way adaptation of existing academic literacy norms. We argue that all teachers should be aware of cultural differences in literacy practices in the education systems and strive to adjust their teaching practices to the diversity in the classroom. This approach, we believe, can contribute to a better learning environment for all students, independently of their backgrounds. 

  15. Perceived Statistical Knowledge Level and Self-Reported Statistical Practice Among Academic Psychologists

    Laura Badenes-Ribera

    2018-06-01

    Full Text Available Introduction: Publications arguing against the null hypothesis significance testing (NHST procedure and in favor of good statistical practices have increased. The most frequently mentioned alternatives to NHST are effect size statistics (ES, confidence intervals (CIs, and meta-analyses. A recent survey conducted in Spain found that academic psychologists have poor knowledge about effect size statistics, confidence intervals, and graphic displays for meta-analyses, which might lead to a misinterpretation of the results. In addition, it also found that, although the use of ES is becoming generalized, the same thing is not true for CIs. Finally, academics with greater knowledge about ES statistics presented a profile closer to good statistical practice and research design. Our main purpose was to analyze the extension of these results to a different geographical area through a replication study.Methods: For this purpose, we elaborated an on-line survey that included the same items as the original research, and we asked academic psychologists to indicate their level of knowledge about ES, their CIs, and meta-analyses, and how they use them. The sample consisted of 159 Italian academic psychologists (54.09% women, mean age of 47.65 years. The mean number of years in the position of professor was 12.90 (SD = 10.21.Results: As in the original research, the results showed that, although the use of effect size estimates is becoming generalized, an under-reporting of CIs for ES persists. The most frequent ES statistics mentioned were Cohen's d and R2/η2, which can have outliers or show non-normality or violate statistical assumptions. In addition, academics showed poor knowledge about meta-analytic displays (e.g., forest plot and funnel plot and quality checklists for studies. Finally, academics with higher-level knowledge about ES statistics seem to have a profile closer to good statistical practices.Conclusions: Changing statistical practice is not

    Medical students and residents often make specialty and practice choices with limited exposure to aspects of professional and personal life in general surgery. The purpose of this study was to portray practice composition, career choices, professional experiences, job satisfaction, and personal life characteristics specific to practicing general surgeons in the United States. A 131-question survey was mailed to all female members (n = 1,076) and a random 2:1 sample of male members (n = 2,152) of the American College of Surgeons in three mailings between September 1998 and March 1999. Respondents who were not actively practicing general surgery in the United States and both trainees and surgeons who did not fit the definition of private or academic practice were excluded. Detailed questions regarding practice attributes, surgical training, professional choices, harassment, malpractice, career satisfaction, and personal life characteristics were included. Separate five-point Likert scales were designed to measure influences on career choices and satisfaction with professional and personal matters. Univariate analyses were used to analyze responses by surgeon age, gender, and practice type. A response rate of 57% resulted in 1,532 eligible responses. Significant differences between private and academic practice were noted in case composition, practice structure, and income potential; no major differences were seen in malpractice experience. Propensity for marriage and parenthood differed significantly between men and women surgeons. Overall career satisfaction was very high regardless of practice type. Some differences by surgeon gender in perceptions of equal career advancement opportunities and of professional isolation were noted. This study offers a comprehensive view of general surgery to enable more informed decisions among medical students and residents regarding specialty choice or practice opportunities.

    Full Text Available As VCRs and DVD players become obsolete, online course offerings increase, and flipped pedagogy becomes ubiquitous, academic librarians are frequently confronted with requests from instructors for streaming media. The authors of this article describe the reasoning for and process by which a policy and best practices to manage streaming media requests were developed at a large public university. This policy is guided by the principles set forth in U.S. Copyright Act’s fair use doctrine (17 U.S.C. § 107 and ARL’s Code of Best Practices in Fair Use for Academic and Research Libraries (2012. The policy also includes a workflow for delivering streaming, ADA-compliant video content that cannot be licensed via conventional library means. Moreover, the comparative costs of purchasing subscription video collections versus licensing individual streaming videos at George Mason University are provided for the fiscal years 2013 through 2016.

    Using data from the National Institute of Child Health and Human Development Study of Early Child Care and Youth Development and a model-building approach, the authors examined direct and indirect associations between first-grade (G1) classroom-level adversity (CLA), G1 teaching practices, and student (N = 1,073; M = 6.64 years; 49% girls; 82% White) academic skills and executive functioning in G1 and third grades (G3). Teachers reported the prevalence of adversity among their students (e.g., poor home/family life, poor academic/social readiness). Observers rated G1 teaching practices: teachers' classroom management, controlling instruction, and amount of academic instruction (classroom observation system). Children completed literacy and math assessments at 54 months, G1, and G3 (Woodcock Johnson Letter-Word Identification and Applied Problems), and executive functioning at G1 and G3 (Tower of Hanoi). Direct associations emerged between CLA and controlling instruction (positive), classroom management, and academic instruction (both negative). In addition, CLA was related to G1 literacy (but not math) directly and indirectly via classroom management (negatively) and controlling instruction (positively). The addition of G3 outcomes revealed a negative direct longitudinal association between CLA and G3 executive functioning, and indirect associations with G3 literacy and math through G1 teaching practices and literacy. Results support the notion that collective student characteristics influence student outcomes in part through teaching practices and suggest that teachers and students may benefit from the diffusion of high-adversity classroom compositions when possible. Moreover, in high-adversity classrooms teachers and students may benefit from supports targeting classroom management and foundational student competencies.

    Full Text Available The article examines the methods applied by graduate master’s degree students of the Faculty of Civil Engineering of Vilnius Gediminas Technical University for the purposes of using knowledge of language for specific purposes in the work and study environment. Their linguistic situation is ambivalent: they act in the academic environment, and therefore the used language has to meet academic requirements; on the other hand, most of them are adapting to the linguistic environment at work. Thus, master’s degree students are able to view the subject of language for specific purposes and the knowledge and skills gained from a practical perspective. With the help of a questionnaire and an interview, the article is aimed at assessing the experience of applying the knowledge gained by the students who completed a course on language for specific purposes 2–5 years ago. The article analyses both academic and practical applications regarding knowledge of language for specific purposes. Extralinguistic factors are taken into account when examining why employed master’s degree students do not always use what they have learnt. The problems of the practical application of knowledge are closely related to the cultural situation; hence, the relevant issues of the postmodern epoch are discussed. The paper explores the interconnection of the practical application of knowledge that covers economic and political factors and globalisation. The study focuses on the academic application of knowledge about the language for specific purposes. Attention is paid to dangers posed for the youth language by the predominance of information technologies in higher education institutions. The article analyses how employed master’s degree students evaluate the course on language for specific purposes and the linguistic revision of MA theses, as well as explores how the knowledge provided meets their needs.

  1. How do nurse academics value and engage with evidence-based practice across Australia: Findings from a grounded theory study.

    Integrating evidence-based practice (EBP) into undergraduate education and preparing future nurses to embrace EBP in clinical practice becomes paramount in today's complex and evolving healthcare environment. The role that EBP plays in the practical lives of nursing students will depend on the degree to which it is promoted by academics, how it is incorporated into courses and its application to clinical setting. Hence, nursing academics play a crucial role in influencing its integration into curricula. Drawn from a larger doctoral study, this paper presents findings discussing how nurse academics value and engage with EBP. Grounded theory was employed to explore processes used by nursing academics while incorporating EBP into teaching and learning practices. Twenty-three academics across Australian universities were interviewed. Nine were also observed while teaching undergraduate students. Data were collected from semi-structured interviews and non-participant observation. In keeping with the tenets of grounded theory, data collection and analysis continued until theoretical saturation was reached. In total, four categories emerged. This paper focuses on the category conceptualised as Valuing and Engaging with EBP. How nursing academics valued and engaged with EBP was closely associated with meanings they constructed around understanding it, attitudes and commitment to implementation while teaching and working clinically. Different opinions also existed in regard to what actually constituted EBP. However, they engaged with and valued EBP by keeping themselves up-to-date, being involved in research activities, using evidence in teaching, therefore leading by example. Participants identified a number of barriers influencing their engagement with EBP including heavy workloads, limited time, lack of commitment within their schools, lack of confidence with teaching EBP, and complexity of EBP application.

    Silkworm genebanks assume paramount importance as the reservoirs of biodiversity and source of alleles that can be easily retrieved for genetic enhancement of popular breeds. More than 4000 Bombyx mori L (Lepidoptera: Bombycidae) strains are currently available and these strains are maintained through continuous sibling mating. This repeated sibling mating makes the populations of each strain more homozygous, but leads to loss of unique and valuable genes through the process of inbreeding depression. Hence, it is essential to maintain a minimal degree of heterozygosity within the population of each silkworm strain, especially in the traditional geographic strains, to avoid such loss. As a result, accurate estimation of genetic diversity is becoming more important in silkworm genetic resources conservation. Application of molecular markers help estimate genetic diversity much more accurately than that of morphological traits. Since a minimal amount of heterozygosity in each silkworm strain is essential for better conservation by avoiding inbreeding depression, this article overviews both theoretical and practical importance of heterozygosity together with impacts of inbreeding depression and the merits and demerits of neutral molecular markers for measurements of both heterozygosity and inbreeding depression in the silkworm Bombyx mori.

    avoidance can be because of low risk of inbreeding, variation in tolerance to inbreeding or high costs of outbreeding. We examined the relationship between inbreeding depression and inbreeding avoidance adaptations under two levels of inbreeding in the spider Oedothorax apicatus, asking whether preference...... for unrelated sperm via pre- and/or post-copulatory mechanisms could restore female fitness when inbreeding depression increases. Using inbred isofemale lines we provided female spiders with one or two male spiders of different relatedness in five combinations: one male sib; one male nonsib; two male sibs; two...

    Full Text Available This study investigated the perceptions of academic fieldwork coordinators (AFWCs regarding emerging areas of practice as fieldwork experiences for entry-level occupational therapy (OT students. Further, this study explored several aspects of fieldwork experiences in emerging areas of practice on student personal and professional development, academic curriculum, partnering community agencies, and the profession at large. A survey designed through Qualtrics®, an electronic survey system, was sent to 163 AFWCs of fully accredited master’s and doctoral entry-level OT programs. Forty-four participants (27% completed the 16-question survey. Significance at p < .05 was found in higher levels of Bloom’s taxonomy student performance when compared to traditional areas of practice. Common perceptions found among the AFWCs related to emerging areas of practice fieldwork experiences included: improved student professional and personal skills, increased connections and collaborations across and in health care disciplines, an enhanced ability to define and understand OT. Continued opportunities for fieldwork in emerging areas of practice are essential as the profession contemplates new markets and avenues in a changing health care environment.

    Academic medical centers (AMCs) need new approaches to delivering higher-quality care at lower costs, and engaging trainees in the work of high-functioning primary care practices. In 2012, the Harvard Medical School Center for Primary Care, in partnership with with local AMCs, established an Academic Innovations Collaborative (AIC) with the goal of transforming primary care education and practice. This novel two-year learning collaborative consisted of hospital- and community-based primary care teaching practices, committed to building highly functional teams, managing populations, and engaging patients. The AIC built on models developed by Qualis Health and the Institute for Healthcare Improvement, optimized for the local AMC context. Foundational elements included leadership engagement and development, application of rapid-cycle process improvement, and the creation of teams to care for defined patient populations. Nineteen practices across six AMCs participated, with nearly 260,000 patients and 450 resident learners. The collaborative offered three 1.5-day learning sessions each year featuring shared learning, practice coaches, and improvement measures, along with monthly data reporting, webinars, and site visits. Validated self-reports by transformation teams showed that practices made substantial improvement across all areas of change. Important factors for success included leadership development, practice-level resources, and engaging patients and trainees. The AIC model shows promise as a path for AMCs to catalyze health system transformation through primary care improvement. In addition to further evaluating the impact of practice transformation, expansion will require support from AMCs and payers, and the application of similar approaches on a broader scale.

    Narayanasamy, Kogilah; Shetty, M. V.

    The study on ethical values in academic programmes has attracted the attention of many researchers throughout the world especially in view of its important role today. Many academic programmes today focus on how to make profit both for the individual and the organization and on how to increase the firm`s market share and shareholders value and in the process may compromise on their ethical values and have unethical practices. Thus, this study is undertaken to evaluate the extent of integration of ethical values in the academic programmes of the higher learning operating institution involved with post graduate and higher level programs. The impact of demographics and race of the lecturer and students have been separately ascertained. The sample has been taken from one college, rated to be high in ethical values and practices, a sample of 120 students and 31 lecturers from a leading college (reputed for ethical values) have been collated and analyzed for validation of the objectives. The explanation on ethics has been done to a large extent in the study. The study also indicates the number of higher learning institutions to indicate the extent of impact if these issues are appropriately addressed. Government policy in this regard also needs to be reviewed and improved to avoid deterioration of ethical values and practices in the dynamic market place of today. This study review that, the level at which lecturers at the institutions have high ethical values and do incorporate it in their lectures and discussions in the classroom. The impact of demographic factors on the ethical values and practice of the lecturers have useful insights for academic staff recruitment and staff training. On the other hand, students` ethical values and behavior is a cause for concern to everyone as these future pillars of the nation have been found to have their ethical values and practices at low levels. The implications for the college management as to consider further emphasis on the

    Full Text Available This paper discusses some of the results obtained in an educational project carried out in a Portuguese undergraduate course at Universidade Federal do Pará. We analyzed the interactional dynamic experienced by students in Facebook when it is used as a teaching platform, as well as the use of writing in these interactions. We understand that the use of digital literacy tools can greatly contribute to the training of future Portuguese language teachers, considering that such tools have directly influenced language practices. Integral formation of our students is one of our main objectives, so we intent not just preparing them for academic practice, but also for future teaching practice in a context which technology and digital tools will be increasingly present. Thus, we aim at contributing to the expansion of digital and academic literacy of our students. Blended Learning, a mix of face-to-face and on line teaching was the methodology used in the project. That way, we believe that learning could become a more continuous process. Our research is theoretically founded on the Studies about Literacy, as Martin (2008, Street (2014 and Lankshear and Knobel (2008 and by Levy (2010 Cyberculture. This ethnographic research analyses the, literacy in context, understood as social practice.

The design is based on a single case study. The study analyzes the results obtained in a third- year course at the University of Valladolid (Spain that participated in an ECTS pilot program. Data was collected during academic year 2009-10. Total number of registered students was 77. This paper describes the procedure to develop a formative assessment system and collect data, as well as the main techniques to obtain and analyze data. Findings indicate that there are important differences in student academic performance depending on the learning and assessment method employed in an academic course. Courses are using formative and on going assessment result in significantly higher student academic performance than courses using other learning and assessment methods. Lastly, empirical data suggest that the workload is in line with the ECTS European Credit Transfer System, and is no excessive for the professor. However, students´ subjective perception is that this method involves a heavier workload. These findings may be important, given the current process of convergence towards the new Degrees and ECTS credit system, and the need to adapt these degrees and credits to students’ real workload.

    Responding to local and national concerns about the nursing workforce, the California Institute for Nursing and Health Care worked with private and public funders and community health care partners to establish community-based transition-to-practice programs for new RN graduates unable to secure nursing positions in the San Francisco Bay Area. The goals were to retain new RN graduates in nursing and further develop their skills and competencies to increase their employability. Leaders from academic and inpatient, ambulatory, and community-based practice settings, as well as additional community partners, collaboratively provided four 12- to 16-week pilot transition programs in 2010-2011. A total of 345 unemployed new nurse graduates enrolled. Eighty-four percent of 188 respondents to a post-program survey were employed in inpatient and community settings 3 months after completion. Participants and clinical preceptors also reported increases in confidence and competence. Copyright 2014, SLACK Incorporated.

    The goal of this study was to implement an evidence-based teamwork system to improve communication and teamwork skills among health care professionals (TeamSTEPPS) into an academic interventional ultrasound program and to assess safety and team-work climate across team members both before and after implementation. Members of a change team (including master trainers) selected specific tools available within TeamSTEPPS to implement into an academic interventional ultrasound service. Tools selected were based on preimplementation survey data obtained from team members (n = 64: 11 attending faculty physicians, 12 clinical abdominal imaging fellows or residents, 17 sonographers, 19 nurses, and five technologist aides or administrative personnel). The survey included teamwork climate and safety climate domains from the Safety Attitudes Questionnaire. Four months after implementation, respondents were resurveyed and post-implementation data were collected. Teamwork climate scores improved from a mean of 67.9 (SD, 12.8) before implementation to a mean of 87.8 (SD, 14.1) after implementation (t = -7.6; p ultrasound practice. The most notable improvements were seen in communication among team members and role clarification. We think that this model, which has been successfully implemented in many nonradiologic areas in medical care, is also applicable in imaging practice.

    Majumder, P P; Malhotra, K C

    1979-01-01

    Data on the distance between the birthplaces of spouses (matrimonial distance) were collected from 2,260 married individuals belonging to 21 endogamous castes of the Dhangar (shepherd) cast-cluster of Maharashtra, India. The general form of the distribution of matrimonial distances is one which is extremely positively skewed and leptokurtic. The percentage of intra-village marriages generally decreases from the southern areas of Maharashtra to the northern areas of the state, as does the inbreeding coefficient. This situation is in conformity with the socio-cultural norms regulating matrimonial choice in south and north India. An attempt has been made to relate the degree of inbreeding to the mean matrimonial distance and population size. The mean matrimonial distance is more useful in predicting the degree of inbreeding than population size.

    The difficulty of obtaining pedigrees for wild populations has hampered the possibility of demonstrating inbreeding depression in nature. In a small, naturally restored, wild population of grey wolves in Scandinavia, founded in 1983, we constructed a pedigree for 24 of the 28 breeding pairs established in the period 1983-2002. Ancestry for the breeding animals was determined through a combination of field data (snow tracking and radio telemetry) and DNA microsatellite analysis. The population was founded by only three individuals. The inbreeding coefficient F varied between 0.00 and 0.41 for wolves born during the study period. The number of surviving pups per litter during their first winter after birth was strongly correlated with inbreeding coefficients of pups (R2=0.39, pwolf population.

    2012-12-01

    Full Text Available The purpose of this study was to investigate inbreeding depression (DE in castor bean. From a population derived from the Guarani cultivar, 60 mother plants were sampled. Three types of progenies were obtained from each one: from self-pollination (AU, from crosses (CR and from open pollination (PL. Grain yield of the progenies was evaluated in two locations. There was a strong interaction of progenies x locations, which led to obtaining estimates within each location. Broad variation was observed in inbreeding depression, with mean values of 6.7% and 13.4%, comparing AU progenies with PL progenies. It was observed that the population has high potential for selecting promising inbred lines. The frequency of mother plants generating progenies with simultaneous high general combination capacity and low inbreeding depression was low. Recurrent selection will increase the occurrence of parent plants associating these two properties, which is necessary for obtaining superior synthetic varieties.

  20. Inbreeding in Mimulus guttatus reduces visitation by bumble bee pollinators.

    Directory of Open Access Journals (Sweden)

    David E Carr

    Full Text Available Inbreeding in plants typically reduces individual fitness but may also alter ecological interactions. This study examined the effect of inbreeding in the mixed-mating annual Mimulus guttatus on visitation by pollinators (Bombus impatiens in greenhouse experiments. Previous studies of M. guttatus have shown that inbreeding reduced corolla size, flower number, and pollen quantity and quality. Using controlled crosses, we produced inbred and outbred families from three different M. guttatus populations. We recorded the plant genotypes that bees visited and the number of flowers probed per visit. In our first experiment, bees were 31% more likely to visit outbred plants than those selfed for one generation and 43% more likely to visit outbred plants than those selfed for two generations. Inbreeding had only a small effect on the number of flowers probed once bees arrived at a genotype. These differences were explained partially by differences in mean floral display and mean flower size, but even when these variables were controlled statistically, the effect of inbreeding remained large and significant. In a second experiment we quantified pollen viability from inbred and self plants. Bees were 37-54% more likely to visit outbred plants, depending on the population, even when controlling for floral display size. Pollen viability proved to be as important as floral display in predicting pollinator visitation in one population, but the overall explanatory power of a multiple regression model was weak. Our data suggested that bees use cues in addition to display size, flower size, and pollen reward quality in their discrimination of inbred plants. Discrimination against inbred plants could have effects on plant fitness and thereby reinforce selection for outcrossing. Inbreeding in plant populations could also reduce resource quality for pollinators, potentially resulting in negative effects on pollinator populations.

  1. Innovative Practice in Advancement of Academic Nurse Educator Careers: Developing Scholarship From Program Grants.

    Eddy, Linda L; Hoeksel, Renee; Fitzgerald, Cindy; Doutrich, Dawn

    We describe an innovative practice in advancing careers of academic nurse educators: demonstrating scholarly productivity from program grants. Scholarly productivity is often narrowly defined, especially in research-intensive institutions. The expectation may be a career trajectory based on the traditional scholarship of discovery. However, nurse educators, especially at the associate and full professor ranks, are often involved in leadership activities that include writing and managing program grants. We encourage the academy to value and support the development of program grants that include significant scholarly components, and we offer exemplars of associate and full professor scholarship derived from these projects.

  2. Assessment of inbreeding depression in Nellore cows (Bos indicus) through high-density SNP genotypes

    Inbreeding is widely believed to negatively affect reproductive performance. Indeed, in some species, high levels of inbreeding are thought to be the major cause of poor semen quality. It is, however, not clear whether inbreeding affects fertility in horses. In this study, the relationship between

    Academic health sciences libraries in the United States and Canada were surveyed regarding collection development trends, including their effect on approval plan and blanket order use, and use of outsourcing over the past four years. Results of the survey indicate that serials market forces, budgetary constraints, and growth in electronic resources purchasing have resulted in a decline in the acquisition of print items. As a result, approval plan use is being curtailed in many academic health sciences libraries. Although use of blanket orders is more stable, fewer than one-third of academic health sciences libraries report using them currently. The decline of print collections suggests that libraries should explore cooperative collection development of print materials to ensure access and preservation. The decline of approval plan use and the need for cooperative collection development may require additional effort for sound collection development. Libraries were also surveyed about their use of outsourcing. Some libraries reported outsourcing cataloging and shelf preparation of books, but none reported using outsourcing for resource selection. The reason given most often for outsourcing was that it resulted in cost savings. As expected, economic factors are driving both collection development and outsourcing practices.

    1989-07-21

    Academic medical centers are facing the need to expand their primary care referral base in an increasingly competitive medical environment. This study describes the medical care provided during a 1-year period to 6304 patients registered with a family practice clinic located in an academic medical center. The relative distribution of primary care, secondary referrals, inpatient admissions, and their associated costs are presented. The multiplier effect of the primary care clinic on the academic medical center was substantial. For every $1 billed for ambulatory primary care, there was $6.40 billed elsewhere in the system. Each full-time equivalent family physician generated a calculated sum of $784,752 in direct, billed charges for the hospital and $241,276 in professional fees for the other specialty consultants. The cost of supporting a primary care clinic is likely to be more than offset by the revenues generated from the use of hospital and referral services by patients who received care in the primary care setting.

    Full Text Available The study of inbreeding depression is important for breeding strategies such as use of inbred progenies or extraction of inbreed lines. A diallel of 28 maize open-pollinated varieties was evaluated in 10 environments in the early 1990s. At the same time, S1 populations for each of the 28 varieties were evaluated in the same 10 experiments (environments. Yield reductions of the populations from S0 to S1 (mean of the 10 environments, varied from 34.6% (CMS-01 to 59.2% (CMS-30, with an average of 49.1%. Inbreeding depression was greater in populations with a wider genetic base, which had never been exposed to inbreeding (CMS-30, BR-107, PH4, Cunha, Saracura, Nitrodent, and Nitroflint. Inbred lines with greater yield means should be obtained from the BR-105, BR-111, CMS-01, CMS-03, BR-106, CMS-14c, and CMS-28 populations. The use of parameter estimates generated by analysis of inbreeding depression, allow to make inferences about frequencies of deleterious alleles in the population. The frequencies of favorable alleles in the parents can be obtained by diallel analysis. The association of these two types of information, can provide a better interpretation of the genetic parameters and also can improve the process of selection of parents for either an intra- or an inter-populational breeding program.

    Echevarria, Mercedes

    A knowledge translation project involving an academic-practice partnership and guided by action-oriented research was used for exploring barriers that impact management of homebound heart failure patients. The intervention process followed an action research model of interaction, self-reflection, response, and change in direction. External facilitators (academia) and internal facilitators (practice) worked with clinicians to identify a topic for improvement, explore barriers, locate the evidence compare current practice against evidence-based practice recommendations, introduce strategies to "close the gap" between actual practice and the desired practice, develop audit criteria, and reevaluate the impact.

  18. Mating system and ploidy influence levels of inbreeding depression in Clarkia (Onagraceae).

    Science.gov (United States)

    Barringer, Brian C; Geber, Monica A

    2008-05-01

    Inbreeding depression is the reduction in offspring fitness associated with inbreeding and is thought to be one of the primary forces selecting against the evolution of self-fertilization. Studies suggest that most inbreeding depression is caused by the expression of recessive deleterious alleles in homozygotes whose frequency increases as a result of self-fertilization or mating among relatives. This process leads to the selective elimination of deleterious alleles such that highly selfing species may show remarkably little inbreeding depression. Genome duplication (polyploidy) has also been hypothesized to influence levels of inbreeding depression, with polyploids expected to exhibit less inbreeding depression than diploids. We studied levels of inbreeding depression in allotetraploid and diploid species of Clarkia (Onagraceae) that vary in mating system (each cytotype was represented by an outcrossing and a selfing species). The outcrossing species exhibited more inbreeding depression than the selfing species for most fitness components and for two different measures of cumulative fitness. In contrast, though inbreeding depression was generally lower for the polyploid species than for the diploid species, the difference was statistically significant only for flower number and one of the two measures of cumulative fitness. Further, we detected no significant interaction between mating system and ploidy in determining inbreeding depression. In sum, our results suggest that a taxon's current mating system is more important than ploidy in influencing levels of inbreeding depression in natural populations of these annual plants.

    This systematic review was designed to assess the importance of academic literacy for undergraduate nursing students and its relationship to future professional clinical practice. It aimed to explore the link between academic literacy and writing in an undergraduate nursing degree and the development of critical thinking skills for their future professional clinical practice. A systematic review of qualitative studies and expert opinion publications. A systematic literature search was undertaken of the following databases: ERIC, PubMed, CINAHL, MEDLINE and Scopus. All papers reviewed were from 2000 to 2016 and were written in English. We identified 981 studies and expert opinion papers from the selected databases. After reviewing key words and abstracts for the inclusion and exclusion criteria, 48 papers were selected for review. These were read and reread, with 22 papers, including one thesis, selected for quality appraisal. One paper was discarded due to the exclusion criteria. Three major themes were evident from this study. First, students need assistance to develop tertiary level academic literacy skills when they commence their undergraduate nursing degree. Second, that teaching practices need to be consistent in both designing assessments and in giving feedback to students, in order to assist improvement of academic literacy skills. And finally, academic literacy can facilitate critical thinking when students are assessed using discipline specific genres that relate to their future professional nursing practice. This review highlights the importance of critical thinking in clinical nursing practice and its strong relationship with academic writing skills. It has shown critical thinking is discipline specific and nursing students need to be taught discipline specific literacy genres in undergraduate nursing degrees. Nursing has a diverse educational and cultural mix of students, and educators should not assume academic literacy skills upon commencement of an

    The effects of increased pedigree inbreeding in dairy cattle populations have been well documented and result in a negative impact on profitability. Recent advances in genotyping technology have allowed researchers to move beyond pedigree analysis and study inbreeding at a molecular level. In this study, 5,853 animals were genotyped for 54,001 single nucleotide polymorphisms (SNP); 2,913 cows had phenotypic records including a single lactation for milk yield (from either lactation 1, 2, 3, or 4), reproductive performance, and linear type conformation. After removing SNP with poor call rates, low minor allele frequencies, and departure from Hardy-Weinberg equilibrium, 33,025 SNP remained for analyses. Three measures of genomic inbreeding were evaluated: percent homozygosity (FPH), inbreeding calculated from runs of homozygosity (FROH), and inbreeding derived from a genomic relationship matrix (FGRM). Average FPH was 60.5±1.1%, average FROH was 3.8±2.1%, and average FGRM was 20.8±2.3%, where animals with larger values for each of the genomic inbreeding indices were considered more inbred. Decreases in total milk yield to 205d postpartum of 53, 20, and 47kg per 1% increase in FPH, FROH, and FGRM, respectively, were observed. Increases in days open per 1% increase in FPH (1.76 d), FROH (1.72 d), and FGRM (1.06 d) were also noted, as well as increases in maternal calving difficulty (0.09, 0.03, and 0.04 on a 5-point scale for FPH, FROH, and FGRM, respectively). Several linear type traits, such as strength (-0.40, -0.11, and -0.19), rear legs rear view (-0.35, -0.16, and -0.14), front teat placement (0.35, 0.25, 0.18), and teat length (-0.24, -0.14, and -0.13) were also affected by increases in FPH, FROH, and FGRM, respectively. Overall, increases in each measure of genomic inbreeding in this study were associated with negative effects on production and reproductive ability in dairy cows.

    Pressure on physicians to increase productivity is rising in parallel with administrative tasks, regulations, and the use of electronic health records (EHRs). Physician extenders and clinical pathways are already in use to increase productivity and reduce costs and burnout, but other strategies are required. We evaluated whether implementation of medical scribes in an academic urology clinic would affect productivity, revenue, and patient/provider satisfaction. Six academic urologists were assigned scribes for 1 clinic day per week for 3 months. Likert-type patient and provider surveys were developed to evaluate satisfaction with and without scribes. Matched clinic days in the year prior were used to evaluate changes in productivity and physician/hospital charges and revenue. After using scribes for 3 months, providers reported increased efficiency (p value = 0.03) and work satisfaction (p value = 0.03), while seeing a mean 2.15 more patients per session (+ 0.96 return visits, + 0.99 new patients, and + 0.22 procedures), contributing to an additional 2.6 wRVUs, $542 in physician charges, and $861 in hospital charges per clinic session. At a gross collection rate of 36%, actual combined revenue was + $506/session, representing a 26% increase in overall revenue. At a cost of $77/session, the net financial impact was + $429 per clinic session, resulting in a return-to-investment ratio greater than 6:1, while having no effect on patient satisfaction scores. Additionally, with scribes, clinic encounters were closed a mean 8.9 days earlier. Implementing medical scribes in academic urology practices may be useful in increasing productivity, revenue, and provider satisfaction, while maintaining high patient satisfaction.

    results in more sires having progeny at each generation and thus this breeding practice is likely the major reason for the remarkable levels of genetic diversity retained within these populations. The fact that the EV population is regionally restricted and its small census size of herd-book cows explain its high level of genomic inbreeding.

    2010-11-01

    The development and implementation of a new pharmacy practice model at an academic medical center are described. Before the model change, decentralized pharmacists responsible for order entry and verification and clinical specialists were both present on the care units. Staff pharmacists were responsible for medication distribution and sterile product preparation. The decentralized pharmacists handling orders were not able to use their clinical training, the practice model was inefficient, and few clinical services were available during evenings and weekends. A task force representing all pharmacy department roles developed a process and guiding principles for the model change, collected data, and decided on a model. Teams consisting of decentralized pharmacists, decentralized pharmacy technicians, and team leaders now work together to meet patients' pharmacy needs and further departmental safety, quality, and cost-saving goals. Decentralized service hours have been expanded through operational efficiencies, including use of automation (e.g., computerized provider order entry, wireless computers on wheels used during rounds with physician teams). Nine clinical specialist positions were replaced by five team leader positions and four pharmacists functioning in decentralized roles. Additional staff pharmacist positions were shifted into decentralized roles, and the hospital was divided into areas served by teams including five to eight pharmacists. Technicians are directly responsible for medication distribution. No individual's job was eliminated. The new practice model allowed better alignment of staff with departmental goals, expanded pharmacy hours and services, more efficient medication distribution, improved employee engagement, and a staff succession plan.

  4. Evaluation of Optimum Genetic Contribution Theory to Control Inbreeding While Maximizing Genetic Response

    2012-03-01

    Full Text Available Inbreeding is the mating of relatives that produce progeny having more homozygous alleles than non-inbred animals. Inbreeding increases numbers of recessive alleles, which is often associated with decreased performance known as inbreeding depression. The magnitude of inbreeding depression depends on the level of inbreeding in the animal. Level of inbreeding is expressed by the inbreeding coefficient. One breeding goal in livestock is uniform productivity while maintaining acceptable inbreeding levels, especially keeping inbreeding less than 20%. However, in closed herds without the introduction of new genetic sources high levels of inbreeding over time are unavoidable. One method that increases selection response and minimizes inbreeding is selection of individuals by weighting estimated breeding values with average relationships among individuals. Optimum genetic contribution theory (OGC uses relationships among individuals as weighting factors. The algorithm is as follows: i Identify the individual having the best EBV; ii Calculate average relationships ( r j ¯ between selected and candidates; iii Select the individual having the best EBV adjusted for average relationships using the weighting factor k, E B V * = E B V j ( 1 - k r j ¯ . iv Repeat process until the number of individuals selected equals number required. The objective of this study was to compare simulated results based on OGC selection under different conditions over 30 generations. Individuals (n = 110 were generated for the base population with pseudo random numbers of N~ (0, 3, ten were assumed male, and the remainder female. Each male was mated to ten females, and every female was assumed to have 5 progeny resulting in 500 individuals in the following generation. Results showed the OGC algorithm effectively controlled inbreeding and maintained consistent increases in selection response. Difference in breeding values between selection with OGC algorithm and by EBV only was 8

    2016-01-01

    Full Text Available This study investigates academic employees' perceptions and experiences of work–life balance (WLB in private Universities in Ogun State. A descriptive research design involves in-depth interviews among 129 academic employees in private Universities in Ogun State. Specifically, the main objectives are to critically examine the practices of work-life balance in the Universities. The study assesses the types of WLB policies and practices within the Universities and factors which influence the employee’s perception of work-life balance within the framework of employment relationship in the various Universities in Nigeria. Using spill-over theory, the findings reveal various dimensions in the academic employees' concept of WLB and show that academic employee experience the strain of work intensification and long hours of work. There is a wide gap between corporate WLB practices and the academic employee understanding of WLB. The paper suggests policy implications which would aid the implementation of WLB policies within Private Universities and suggests directions for future research.

  6. Constitutions of Nature by Teacher Practice and Discourse in Ontario Grade 9 and 10 Academic Science

    Science.gov (United States)

    Hoeg, Darren Glen

    This thesis presents an ethnographic study, based broadly on principles and methods of institutional ethnography, on the constitution of nature by nine Ontario Grade 9 and 10 Academic Science teachers. The intent of this methodological approach is to examine how the daily practice of participants works toward constituting nature in specific ways that are coordinated by the institution (Ontario public school and/or school science). Critical Discourse Analysis and general inductive analysis were performed on interview transcripts, texts related to teaching science selected by participants, and policy documents (i.e. curriculum; assessment policy) that coordinate science teacher practice. Findings indicate specific, dominant, and relatively uniform ontological and epistemological constitutions of nature. Nature was frequently constituted as a remote object, distant from and different than students studying it. More complex representations included constituting nature as a model, machine, or mathematical algorithm. Epistemological constitutions of nature were enacted through practices that engaged students in manipulating nature; controlling nature, and dominating nature. Relatively few practices that allow students to construct different constitutions of nature than those prioritized by the institution were observed. Dominant constitutions generally assume nature is simply the material to study, from which scientific knowledge can be obtained, with little ethical or moral consideration about nature itself, or how these constitutions produce discourse and relationships that may be detrimental to nature. Dominant constitutions of nature represent a type of objective knowledge that is prioritized, and made accessible to students, through science activities that attain a position of privilege in local science teacher cultures. The activities that allow students to attain the requisite knowledge of nature are collected, collated, and shared among existing science teachers

    Full Text Available Objective – To investigate the perceived alignment between academic library services and high-impact practices (HIPs that affect student retention. Design – Survey questionnaire. Setting – Public comprehensive universities in the United States of America with a Carnegie classification of master’s level as of January 2013. Subjects – 68 library deans or directors out of the 271 who were originally contacted. Methods – The author used Qualtrics software to create a survey based on the HIPs, tested the survey for reliability, and then distributed it to 271 universities. Library services were grouped into 1 of 3 library scales: library collection, library instruction, or library facilities. The survey consisted of a matrix of 10 Likert-style questions addressing the perceived level of alignment between the library scales and the HIPs. Each question provided an opportunity for the respondent to enter a “brief description of support practices” (p 477. Additional demographic questions addressed the years of experience of the respondent, undergraduate student enrollment of the university, and whether librarians held faculty rank. Main Results – The author measured Pearson correlation coefficients and found a positive correlation between the library scales and the HIPs. All three library scales displayed a moderately strong positive correlation between first-year seminars and experiences (HIP 1, common intellectual experiences (HIP 2, writing-intensive courses (HIP 4, undergraduate research (HIP 6, diversity and global learning (HIP 7, service learning and community-based learning (HIP 8, internships (HIP 9, and capstone courses and projects (HIP 10.

    2015-10-01

    Full Text Available The paper presents an over view of a new type of degree program that is rapidly emerging and gaining acceptance in the U.S.: the business doctorate for executives. Roughly a dozen of these programs currently exist at institutions accredited by AACSB International, the nation's premier accrediting agency. Although they are research-focused, like their Ph.D counterparts, they are quite different in a number of ways. Among the most important of these: they target applicants with substantial executive experience, they are part time and assume their participants will continue working while in the program, they are interdisciplinary in focus and their emphasis is generally on applying research methods to practical business problems, as opposed to producing published research articles. As a consequence, they are well-positioned to serve as a bridge that increases partnering between academic research and practice. After summarizing the general nature of these programs, the paper considers the structure and objectives of the new Doctor of Business Administration (DBA program being offered by the Muma College of Business at the University of South Florida.

  9. CITATION PRACTICES AND ACADEMIC PLAGIARISM IN THE TEXTUAL ELABORATION OF UNIVERSITY STUDENTS

    Directory of Open Access Journals (Sweden)

    Rubén Comas Forgas

    2011-04-01

    Full Text Available Locate, evaluate, manage and communicate information in writing academic essays have become basic skills that university students should possess. This article presents the results of a descriptive study developed by survey with a sample of 1.025 under-graduate students at the University of the Balearic Islands on the prevalence in the practice of citation and plagiarism when preparing essays. It should be highlighted from the results obtained, on the one hand, the fact that much of the students or directly do not quote resources used in the preparation of their work or do so sporadically or infrequently. Concerning the commission of plagiarism, the percentage of students who admitted carrying out this type of practice is certainly high. Based on these data, as well as those of other studies with similar characteristics, the authors propose, first, the need for increased research efforts to assess and understand the causes of the situation described and, secondly, advocate for the provision and implementation of training initiatives to improve the situation described.

  10. An inbreeding model of associative overdominance during a population bottleneck.

    Science.gov (United States)

    Bierne, N; Tsitrone, A; David, P

    2000-08-01

    Associative overdominance, the fitness difference between heterozygotes and homozygotes at a neutral locus, is classically described using two categories of models: linkage disequilibrium in small populations or identity disequilibrium in infinite, partially selfing populations. In both cases, only equilibrium situations have been considered. In the present study, associative overdominance is related to the distribution of individual inbreeding levels (i.e., genomic autozygosity). Our model integrates the effects of physical linkage and variation in inbreeding history among individual pedigrees. Hence, linkage and identity disequilibrium, traditionally presented as alternatives, are summarized within a single framework. This allows studying nonequilibrium situations in which both occur simultaneously. The model is applied to the case of an infinite population undergoing a sustained population bottleneck. The effects of bottleneck size, mating system, marker gene diversity, deleterious genomic mutation parameters, and physical linkage are evaluated. Bottlenecks transiently generate much larger associative overdominance than observed in equilibrium finite populations and represent a plausible explanation of empirical results obtained, for instance, in marine species. Moreover, the main origin of associative overdominance is random variation in individual inbreeding whereas physical linkage has little effect.

    2017-04-01

    According to the majority of our respondents, financial disincentives (i.e. income at risk, financial clawbacks appear to be most effective as a mechanism to motivate physicians within an academic APP to submit their billings. However, key barriers to successful implementation and delivery of academic APPs include a lack of alignment between government stakeholders, academic leadership and APP physician members and differences in the organizational and accountability structures of APP plans between academic facilities. It is necessary in moving forward to achieve commonly defined standards and frameworks between the various APP models across provinces and academic institutions.

Design – Mixed methods online survey and semi-structured interviews. Setting – Public research university in Australia. Subjects – The survey included responses from 81 postgraduate students. Semi-structured interviews were conducted with 8 postgraduate students and 13 faculty members. Methods – The researchers distributed an 18-item survey via email to approximately 800 people who previously registered for EndNote training sessions. Survey participants were also recruited via a website advertisement. The researchers recruited postgraduate student interview participants from the list of survey respondents. Librarians invited faculty members to participate in the semi-structured interviews. Interview audio recordings were transcribed and coded for data analysis. Main Results – The survey found that 71.4% (n=55 of respondents used reference management software (RMS and 29% (n=22 did not. Over half of the students who did not use an RMS described other ad hoc or “manual” (p. 255 methods for organizing and tracking references.

    Home environmental assessments and interventions delivered via academic practice partnerships (APP) between clinics and schools of nursing may be a low or no cost delivery model of pediatric asthma care and professional education. Patients receive enhanced clinical resources that can improve self-management and healthcare utilization. Additionally, students can practice chronic disease management skills in actual patient encounters. To describe outcomes of the implementation of an APP between a school of nursing and a pediatric asthma specialty clinic (PASC) to deliver a home visit program (HVP). The HVP was designed to reduce emergency department visits and asthma related hospitalizations in PASC patients and provide clinical experiences for nursing students. PASC referred patients to the HVP based on their level of asthma control. Students provided an individualized number of home visits to 17 participants over a nine month period. A 12-month pre- and post-HVP comparison of emergency department visits and asthma related hospitalizations was conducted. Additional information was gathered from stakeholders via an online survey, and interviews with APP partners and HVP families. Children had fewer asthma related hospitalizations post HVP. Findings suggest a reduction in exposure to environmental triggers, improved patient and family management of asthma, and increased PASC knowledge of asthma triggers in the home and increased student knowledge and skills related to asthma management. Multiple clinical and educational benefits may be realized through the development of APPs as an infrastructure supporting targeted interventions in home visits to pediatric asthma patients and their families.

    1. Conservation biologists are concerned about the interactive effects of environmental stress and inbreeding because such interactions could affect the dynamics and extinction risk of small and isolated populations, but few studies have tested for these interactions in nature. 2. We used data from the long-term population study of song sparrows Melospiza melodia on Mandarte Island to examine the joint effects of inbreeding and environmental stress on four fitness traits that are known to be affected by the inbreeding level of adult birds: hatching success, laying date, male mating success and fledgling survival. 3. We found that inbreeding depression interacted with environmental stress to reduce hatching success in the nests of inbred females during periods of rain. 4. For laying date, we found equivocal support for an interaction between parental inbreeding and environmental stress. In this case, however, inbred females experienced less inbreeding depression in more stressful, cooler years. 5. For two other traits, we found no evidence that the strength of inbreeding depression varied with environmental stress. First, mated males fathered fewer nests per season if inbred or if the ratio of males to females in the population was high, but inbreeding depression did not depend on sex ratio. Second, fledglings survived poorly during rainy periods and if their father was inbred, but the effects of paternal inbreeding and rain did not interact. 6. Thus, even for a single species, interactions between the inbreeding level and environmental stress may not occur in all traits affected by inbreeding depression, and interactions that do occur will not always act synergistically to further decrease fitness.

    Evidence suggests that teamwork is essential for safe, reliable practice. Creating health care teams able to function effectively in patient-centered medical homes (PCMHs), practices that organize care around the patient and demonstrate achievement of defined quality care standards, remains challenging. Preparing trainees for practice in interprofessional teams is particularly challenging in academic health centers where health professions curricula are largely siloed. Here, the authors review a well-delineated set of teamwork competencies that are important for high-functioning teams and suggest how these competencies might be useful for interprofessional team training and achievement of PCMH standards. The five competencies are (1) team leadership, the ability to coordinate team members' activities, ensure appropriate task distribution, evaluate effectiveness, and inspire high-level performance, (2) mutual performance monitoring, the ability to develop a shared understanding among team members regarding intentions, roles, and responsibilities so as to accurately monitor one another's performance for collective success, (3) backup behavior, the ability to anticipate the needs of other team members and shift responsibilities during times of variable workload, (4) adaptability, the capability of team members to adjust their strategy for completing tasks on the basis of feedback from the work environment, and (5) team orientation, the tendency to prioritize team goals over individual goals, encourage alternative perspectives, and show respect and regard for each team member. Relating each competency to a vignette from an academic primary care clinic, the authors describe potential strategies for improving teamwork learning and applying the teamwork competences to academic PCMH practices.

    This paper looks at the opinions of 241 European academics (who provide pharmacy education), and of 258 European community pharmacists (who apply it), on competences for pharmacy practice. A proposal for competences was generated by a panel of experts using Delphi methodology. Once finalized, the proposal was then submitted to a large, European-wide community of academics and practicing pharmacists in an additional Delphi round. Academics and community pharmacy practitioners recognized the importance of the notion of patient care competences, underlining the nature of the pharmacist as a specialist of medicines. The survey revealed certain discrepancies. Academics placed substantial emphasis on research, pharmaceutical technology, regulatory aspects of quality, etc., but these were ranked much lower by community pharmacists who concentrated more on patient care competences. In a sub-analysis of the data, we evaluated how perceptions may have changed since the 1980s and the introduction of the notions of competence and pharmaceutical care. This was done by splitting both groups into respondents 40 years old. Results for the subgroups were essentially statistically the same but with some different qualitative tendencies. The results are discussed in the light of the different conceptions of the professional identity of the pharmacist. PMID:28970385

    This study examined adolescents' perceptions of parenting practices and extended kinship support in relation to academic adjustment for 104 African American and 60 European American 9th and 10th graders (14 and 15 year olds). For African-American teens, parental acceptance was associated with school values, teacher bonding, and work orientation. Higher levels of behavioral control and lower levels of psychological control were associated with a stronger work orientation. After accounting for the demographic variables and the three parenting practices, higher levels of extended kinship support related to stronger school values, higher teacher bonding, and a stronger work orientation. For European-American teens, parental acceptance related to academic adjustment, including stronger school values, higher teacher bonding, and a stronger work orientation. European-American adolescents with stronger extended kinship networks reported higher teacher bonding and a stronger work orientation. Results indicate the importance of extended kinship support for both African-American and European-American adolescents.

    Inbreeding has been associated with the impairment of reproductive performance in many cattle breeds. Although the usage of reproductive biotechnologies has been increasing in bovine populations, not much attention has been given to the impact of inbreeding over cow's performance on artificial reproduction. The objective of this study was to estimate the impact of inbreeding on in vitro embryo production in a Guzerá breed population. The inbreeding coefficient (F), calculated as half of the co-ancestry of the individual's parents, was used as an estimate of inbreeding. The inbreeding coefficients of the donor, sire (used on in vitro fertilization) and of the embryos were included, separately, in the proposed models either as classificatory or continuous variables (linear and quadratic effects). The percentage of non-inbred individuals (or embryos) and mean F of donors, embryos and sires were 29.38%; 35.76%; 42.86% and 1.98±2.68; 1.32±3.13; 2.08±2.79, respectively. Two different models were considered, one for oocyte production traits and other for embryo production traits. The increase of F of the donor significantly (P0.05) effects were observed for the sire (father of the embryos) inbreeding coefficient over the traits analysed. Embryo's F influenced (Ptechnology. High levels of inbreeding should be avoided when selecting Guzerá female donors and planning in vitro fertilization mating.

    A maternal effect is a causal influence of the maternal phenotype on the offspring phenotype over and above any direct effects of genes. There is abundant evidence that maternal effects can have a major impact on offspring fitness. Yet, no previous study has investigated the potential role of maternal effects in influencing the severity of inbreeding depression in the offspring. Inbreeding depression is a reduction in the fitness of inbred offspring relative to outbred offspring. Here, we tested whether maternal effects due to body size alter the magnitude of inbreeding depression in the burying beetle Nicrophorus vespilloides We found that inbreeding depression in larval survival was more severe for offspring of large females than offspring of small females. This might be due to differences in how small and large females invest in an inbred brood because of their different prospects for future breeding opportunities. To our knowledge, this is the first evidence for a causal effect of the maternal phenotype on the severity of inbreeding depression in the offspring. In natural populations that are subject to inbreeding, maternal effects may drive variation in inbreeding depression and therefore contribute to variation in the strength and direction of selection for inbreeding avoidance. © 2016 The Author(s).

    Inbreeding depression is a key factor affecting the persistence of natural populations, particularly when they are fragmented. In species with mixed mating systems, inbreeding depression can be estimated at the population level by regressing the average progeny fitness by the selfing rate of their mothers. We applied this method using simulated populations to investigate how population genetic parameters can affect the detection power of inbreeding depression. We simulated individual selfing rates and genetic loads from which we computed fitness values. The regression method yielded high statistical power, inbreeding depression being detected as significant (5 % level) in 92 % of the simulations. High individual variation in selfing rate and high mean genetic load led to better detection of inbreeding depression while high among-individual variation in genetic load made it more difficult to detect inbreeding depression. For a constant sampling effort, increasing the number of progenies while decreasing the number of individuals per progeny enhanced the detection power of inbreeding depression. We discuss the implication of among-mother variability of genetic load and selfing rate on inbreeding depression studies.

    The concept of neuromodulation via the use of spinal cord stimulators (SCS) was first established over forty years ago. Since then, its popularity has grown as numerous studies have demonstrated its utility to reduce chronic pain, improve patient function, and reduce long-term health care costs. The aim of this study was to update the pain medicine community on the evolution of SCS practice trends in academic centers. Ninety-three pain medicine fellowship programs in the United States were identified from the Accreditation Council for Graduate Medical Education Website and were contacted to participate in an internet survey. A 37-item questionnaire was inspired by a previous study performed by Fanciullo et al. Questions focused on three main themes regarding SCS clinical application, namely demographics, education, and technical matters. Completed surveys were received from 50 institutions, all of which reported performing SCS interventions. Annual implants ranged from 0 to 150. Fellowship training was cited as the most valuable modality for learning implantation. Nearly all programs reported manufacturer representative participation during SCS procedures, with a minority of program directors discouraging their involvement in fellow education. SCS trials were performed exclusively on an outpatient basis. The average length for trials was 4-7 days. The most common indication for SCS implantation was failed back surgery syndrome, which also had the highest 2-year success rate. Post procedure, patients generally were followed up every 2-4 weeks for device reprogramming, which was performed by company representatives 92% of the time. Standardized SCS training is imperative as the implementation of neuromodulation therapy continues to increase. Wiley Periodicals, Inc.

    Background Iron deficiency is a common problem in primary care and is usually treated with oral iron substitution. With the recent simplification of intravenous (IV) iron administration (ferric carboxymaltose) and its approval in many countries for iron deficiency, physicians may be inclined to overutilize it as a first-line substitution. Objective The aim of this study was to evaluate iron deficiency management and substitution practices in an academic primary care division 5 years after ferric carboxymaltose was approved for treatment of iron deficiency in Switzerland. Methods All patients treated for iron deficiency during March and April 2012 at the Geneva University Division of Primary Care were identified. Their medical files were analyzed for information, including initial ferritin value, reasons for the investigation of iron levels, suspected etiology, type of treatment initiated, and clinical and biological follow-up. Findings were assessed using an algorithm for iron deficiency management based on a literature review. Results Out of 1,671 patients, 93 were treated for iron deficiency. Median patients’ age was 40 years and 92.5% (n=86) were female. The average ferritin value was 17.2 μg/L (standard deviation 13.3 μg/L). The reasons for the investigation of iron levels were documented in 82% and the suspected etiology for iron deficiency was reported in 67%. Seventy percent of the patients received oral treatment, 14% IV treatment, and 16% both. The reasons for IV treatment as first- and second-line treatment were reported in 57% and 95%, respectively. Clinical and biological follow-up was planned in less than two-thirds of the cases. Conclusion There was no clear overutilization of IV iron substitution. However, several steps of the iron deficiency management were not optimally documented, suggesting shortcuts in clinical reasoning. PMID:27445502

With the recent simplification of intravenous (IV iron administration (ferric carboxymaltose and its approval in many countries for iron deficiency, physicians may be inclined to overutilize it as a first-line substitution.Objective: The aim of this study was to evaluate iron deficiency management and substitution practices in an academic primary care division 5 years after ferric carboxymaltose was approved for treatment of iron deficiency in Switzerland.Methods: All patients treated for iron deficiency during March and April 2012 at the Geneva University Division of Primary Care were identified. Their medical files were analyzed for information, including initial ferritin value, reasons for the investigation of iron levels, suspected etiology, type of treatment initiated, and clinical and biological follow-up. Findings were assessed using an algorithm for iron deficiency management based on a literature review.Results: Out of 1,671 patients, 93 were treated for iron deficiency. Median patients’ age was 40 years and 92.5% (n=86 were female. The average ferritin value was 17.2 μg/L (standard deviation 13.3 μg/L. The reasons for the investigation of iron levels were documented in 82% and the suspected etiology for iron deficiency was reported in 67%. Seventy percent of the patients received oral treatment, 14% IV treatment, and 16% both. The reasons for IV treatment as first- and second-line treatment were reported in 57% and 95%, respectively. Clinical and biological follow-up was planned in less than two-thirds of the

  7. Rational accountability and rational autonomy in academic practice: An extended case study of the communicative ethic of interdisciplinary science

    Robertson, Susan Margaret

    The dissertation investigates the interaction of rational accountability and rational autonomy in interdisciplinary science within the lifeworld of the university. It focuses on the cultural, social and motivational forces that university researchers draw on, and develop, to constitute and regulate interdisciplinary science. Findings are analyzed within an applied critical social theory framework that attends to the interaction of instrumental and communicative rational action within the public spaces that constitute the lifeworld of the university as a public sphere in society. The research raises questions of how academics practice interdisciplinary science and how these practices relate to the reproduction of the regulative ideal of the university as a community that practices public reason. The conceptual framework informing the research is Habermas' (1984) theory of communicative action. Using Burawoy's (1991) extended case study method as an operational strategy, two modes of constituting and regulating interdisciplinary science were found. Instrumental rational modes dominated in social contexts of interdisciplinary science where consensus on the normative goals and purposes of rational academic action were pre-existing and pre-supposed by participants. Communicative rational modes dominated in social contexts of interdisciplinary science where the normative goals and purposes of rational academic action entered a contested domain. Endorsements for interdisciplinary science policies are coinciding with demands for increased accountability and relevance of Canada's university system. At the same time that the university system must respond to external demands, it must reproduce itself as a public institution open to the discursive redemption of factual and normative validity claims. The study found that academics participate in, but also contest the instrumental regulation of academic inquiry and conduct by using their constitutional autonomy and freedom to

    Full Text Available Based on statistical data, contemporary trends within academic libraries in the Republic of Slovenia are presented. The substantially slow increase of library materials, along with lesser increase of staff, contradicts the growing number of library visits and circulation. The paper elaborates on outstanding differences regarding personnel, financial, and spatial issues of the libraries concerned. The comparison between the professional and govemmental standards and norms is presented. At a time when academic libraries are faced with the dilemma of growing demand from users at the same time as budgetary constraint there is an urgent need to develop a list of performance indicators and to modernize professional standards and norms for academic libraries.The elaboration of new standards must be based on empirical studies. Only realistic and clearly defined norms would enable the implementation of standards and improve the quality and efficiency of academic libraries.

  9. Current Understandings of the Research-Practice Gap From the Viewpoint of Complementary Medicine Academics: A Mixed-Method Investigation.

    Leach, Matthew J; Tucker, Basil

    Research plays an important role in advancing health and healthcare. However, much research evidence is not reflected in contemporary complementary and alternative medicine (CAM) practice. Understanding and addressing the reasons for this research-practice gap may have positive implications for quality of care. To shed light on the gap between research and CAM practice. Descriptive cross-sectional, mixed-method study. A total of 126 senior CAM academics across Australasia, Europe, UK, and North America. Participants completed a 30-item online survey and a semi-structured interview; both of which explored the research-practice gap in CAM. A total of 43 (34%) academics completed the survey, with 29 (67%) respondents undergoing an interview. There was general agreement among respondents that CAM research should be informed by practice, and practice informed by research; however, most agreed that this did not reflect the current situation. Translational issues were perceived to be the primary reason for the research-practice gap in CAM. Suggested strategies for closing the gap focussed mostly around improving CAM student/practitioner education and training, and researcher-practitioner engagement and collaboration. Study findings point toward the presence of a research-practice gap in CAM, with several factors likely to be instrumental in sustaining this gap. Attention now needs to focus on understanding the views of CAM clinicians on this issue. Insights gained from this research will help inform the development of a multi-modal strategy that will effectively target the barriers to change in order to bring CAM research and practice closer together.

  10. The environmental dependence of inbreeding depression in a wild bird population.

    2007-10-01

    Full Text Available Inbreeding depression occurs when the offspring produced as a result of matings between relatives show reduced fitness, and is generally understood as a consequence of the elevated expression of deleterious recessive alleles. How inbreeding depression varies across environments is of importance for the evolution of inbreeding avoidance behaviour, and for understanding extinction risks in small populations. However, inbreeding-by-environment (IxE interactions have rarely been investigated in wild populations.We analysed 41 years of breeding events from a wild great tit (Parus major population and used 11 measures of the environment to categorise environments as relatively good or poor, testing whether these measures influenced inbreeding depression. Although inbreeding always, and environmental quality often, significantly affected reproductive success, there was little evidence for statistically significant I x E interactions at the level of individual analyses. However, point estimates of the effect of the environment on inbreeding depression were sometimes considerable, and we show that variation in the magnitude of the I x E interaction across environments is consistent with the expectation that this interaction is more marked across environmental axes with a closer link to overall fitness, with the environmental dependence of inbreeding depression being elevated under such conditions. Hence, our analyses provide evidence for an environmental dependence of the inbreeding x environment interaction: effectively an I x E x E.Overall, our analyses suggest that I x E interactions may be substantial in wild populations, when measured across relevant environmental contrasts, although their detection for single traits may require very large samples, or high rates of inbreeding.

    Population isolates are an important tool in identifying and mapping genes of Mendelian diseases and complex traits. The geographical identification of isolates represents a priority from a genetic and health care standpoint. The purpose of this study is to analyze the spatial distribution of consanguinity by random isonymy (F ST) in Argentina and its relationship with the isolates previously identified in the country. F ST was estimated from the surname distribution of 22.6 million electors registered for the year 2001 in the 24 provinces, 5 geographical regions, and 510 departments of the country. Statistically significant spatial clustering of F ST was determined using the SaTScan V5.1 software. F ST exhibited a marked regional and departamental variation, showing the highest values towards the North and West of Argentina. The clusters of high consanguinity by random isonymy followed the same distribution. Recognized Argentinean genetic isolates are mainly localized at the north of the country, in clusters of high inbreeding. Given the availability of listings of surnames in high-capacity storage devices for different countries, estimating F ST from them can provide information on inbreeding for all levels of administrative subdivisions, to be used as a demographic variable for the identification of isolates within the country for public health purposes.

    Orthopaedic residents and attending physicians who report having a supportive spouse show lower levels of burnout and psychological distress than those without supportive spouses. However, little is known about the experiences of the spouses. This nationwide study examines burnout, psychological distress, and marital satisfaction of the spouses and significant others (collectively referred to hereafter as spouses) of orthopaedists in training and in orthopaedic practice in an academic setting. Employing previously reported methodology, 259 spouses of orthopaedic residents and 169 spouses of full-time orthopaedic faculty completed a voluntary, anonymous survey. The survey included three validated instruments (the Maslach Burnout Inventory, the General Psychological Health Questionnaire-12, and the Revised Dyadic Adjustment Scale) and three novel question sets addressing demographic information, relationship issues, stress, and work/life balance. Psychological distress was noted in 18% of resident spouses compared with only 10% of faculty spouses (p = 0.014). Resident spouses reported greater loneliness (p < 0.0009) and stress (p = 0.03) than faculty spouses. Among working spouses, 30% of resident spouses and 13% of faculty spouses showed high levels of emotional exhaustion (p < 0.003). Twenty-eight percent of employed resident spouses and 5% of employed faculty spouses showed problematic levels of depersonalization (p < 0.0001). Twenty-six percent of employed resident spouses and 12% of employed faculty spouses showed a diminished sense of personal accomplishment (p = 0.012). Marital satisfaction was high for both resident and faculty spouses. Decreased satisfaction correlated with excessive mate irritability and fatigue that precluded their mate's involvement in family activities. A gratifying sex life, full-time work outside the home, and spending more than ninety minutes a day with their mate correlated significantly with marital satisfaction. Many orthopaedic

    Full Text Available Although it hasn’t much been considered as such, the Digital Humanities movements (or at least the most theoretically informed parts of it offers a critique “from within” of the recent mutation of the higher education and research systems. This paper offers an analysis, from a Critical Theory perspective, of a key element of this critique: the theory vs. practice debate, which, in the Digital Humanities, is translated into the famous “hack” versus “yack” motto, where DHers usually call for the pre-eminence of the former over the latter. I show how this debate aims to criticize the social situation of employment in academia in the digital age and can further be interpreted with the Cultural industry theoretical concept, as a continuance of the domination of the intellectual labour (ie. yack in this case over the manual labour (hack. Nevertheless, I argue that, pushing this debate to its very dialectical limit in the post-industrial academic labour situation, one realizes that the two terms aren’t in opposition anymore: the actual theory as well as the actual practice are below their very critical concepts in the academic labour. Therefore, I call for a reconfiguration of this debate, aiming at the rediscovering of an actual theory in the academic production, as well as a rediscovering of a praxis, the latter being outside of the scientific realm and rules: it is political.

    Latin America has one of the highest rates of health disparities in the world and is experiencing a steep increase in its number of medical schools. It is not clear if medical school authorities consider social responsibility, defined as the institutional commitment to contribute to the improvement of community well-being, as a priority and if there are any organizational strategies that could reduce health disparities. To study the significance and relevance of social responsibility in the academic training of medical schools in Latin America. The study combined a qualitative thematic literature review of three databases with a quantitative design based on a sample of nine Latin American and non-Latin American countries. The thematic analysis showed high agreement among academic groups on considering medical schools as 'moral agents', part of a 'social contract' and with an institutional responsibility to reduce health disparities mainly through the implementation of strong academic primary care programs. The quantitative analysis showed a significant association between higher development of academic primary care programs and lower level of health disparities by country (P = 0.028). However, the data showed that most Latin American medical schools did not prioritize graduate primary care training. The study shows a discrepancy between the importance given to social responsibility and academic primary care training in Latin America and the practices implemented by medical schools. It highlights the need to refocus medical education policies in the region. © The Author 2014. Published by Oxford University Press. All rights reserved.

  16. Effects of inbreeding on potential and realized immune responses in Tenebrio molitor.

    2011-06-01

    Although numerous studies on vertebrates suggest that inbreeding reduces their resistance against parasites and pathogens, studies in insects have found contradictory evidence. In this study we tested the effect of 1 generation of brother-sister mating (inbreeding) on potential and realized immune responses and other life-history traits in Tenebrio molitor. We found that inbreeding reduced adult mass, pre-adult survival and increased development time, suggesting that inbreeding reduced the condition of the adults and thus potentially made them more susceptible to physiological stress. However, we found no significant effect of inbreeding on the potential immune response (encapsulation response), but inbreeding reduced the realized immune response (resistance against the entomopathogenic fungi, Beauveria bassiana). There was a significant family effect on encapsulation response, but no family effect on the resistance against the entomopathogenic fungi. Given that this latter trait showed significant inbreeding depression and that the sample size for the family-effect analysis was small it is likely that the lack of a significant family effect is due to reduced statistical power, rather than the lack of a heritable basis to the trait. Our study highlights the importance of using pathogens and parasites in immunoecological studies.

    As populations decline to levels where reproduction among close genetic relatives becomes more probable, subsequent increases in homozygous recessive deleterious expression and/or loss of heterozygote advantage can lead to inbreeding depression. Here, we measure how inbreeding across replicate lines of the flour beetle Tribolium castaneum impacts on male reproductive fitness in the absence or presence of male–male competition. Effects on male evolution from mating pattern were removed by enforcing monogamous mating throughout. After inbreeding across eight generations, we found that male fertility in the absence of competition was unaffected. However, we found significant inbreeding depression of sperm competitiveness: non-inbred males won 57 per cent of fertilizations in competition, while inbred equivalents only sired 42 per cent. We also found that the P2 ‘offence’ role in sperm competition was significantly more depressed under inbreeding than sperm ‘defence’ (P1). Mating behaviour did not explain these differences, and there was no difference in the viability of offspring sired by inbred or non-inbred males. Sperm length variation was significantly greater in the ejaculates of inbred males. Our results show that male ability to achieve normal fertilization success was not depressed under strong inbreeding, but that inbreeding depression in these traits occurred when conditions of sperm competition were generated.

    Full Text Available Evaluated was effect of mating (random vs. maximum avoidance of inbreeding under BLUP EBV selection strategy. Existing population structure was under Monte Carlo stochastic simulation analyzed from the point to minimize increase of inbreeding. Maximum avoidance of inbreeding under BLUP selection resulted into comparable increase of inbreeding then random mating in average of 10 generation development. After 10 generations of simulation of mating strategy was observed ΔF= 6,51 % (2 sires, 5,20 % (3 sires, 3,22 % (4 sires resp. 2,94 % (5 sires. With increased number of sires selected, decrease of inbreeding was observed. With use of 4, resp. 5 sires increase of inbreeding was comparable to random mating with phenotypic selection. For saving of genetic diversity and prevention of population loss is important to minimize increase of inbreeding in small populations. Classical approach was based on balancing ratio of sires and dams in mating program. Contrariwise in the most of commercial populations small number of sires was used with high mating ratio.

    There is mounting evidence that inbreeding can have complex effects on social interactions among inbred and outbred individuals. Here, we investigate effects of offspring and maternal inbreeding on parent-offspring communication in the burying beetle Nicrophorus vespilloides. We find effects of the interaction between offspring and maternal inbreeding on maternal behavior. Outbred females provided more direct care toward inbred larvae, while inbred females provided similar levels of direct care toward inbred and outbred larvae. Furthermore, we find direct and indirect effects of offspring inbreeding on offspring begging and maternal behavior, respectively. Inbred larvae spent less time begging than outbred larvae, and (outbred) females provided more direct care and less indirect care toward inbred larvae. Finally, we find effects of the interaction between offspring and maternal inbreeding on larval body mass. Inbred and outbred offspring grew to a similar size when the female was outbred, while inbred offspring were of a smaller size when the female was inbred. Our results suggest that outbred females provided more care toward inbred offspring to compensate for their poor genetic quality. Our study advances our understanding of inbreeding by showing that inbreeding can have direct effects on the behavior of inbred individuals and indirect effects on the behavior of outbred individuals and that indirect effects on outbred individuals may in turn influence the fitness of inbred individuals.

    2017-10-01

    Full Text Available Inbreeding can potentially be used for the development of inbred lines containing alleles of interest, but the genetic causes that control inbreeding depression are not completely known, and there are few studies found in the literature. The present study aimed to obtain estimates of inbreeding depression for eight traits in seven tropical maize populations, analyze the effects of inbreeding over generations and environments, and predict the behavior of inbred lines in future generation S? through linear regression methods. It was found that regardless of the base population used, prediction values could vary when the model was based on only 2 generations of inbreeding due to the environmental component. The influence of the environment in this type of study could be reduced when considering 3 generations of inbreeding, allowing greater precision in predicting the phenotypes of inbred lines. The use of linear regression was effective for inbred line prediction for the different agronomic traits evaluated. The use of 3 levels of inbreeding minimizes the effects of the environmental component in inbred line prediction for grain yield. GO-S was the most promising population for inbred line extraction.

    2008-01-01

    Full Text Available Abstract Background Solanum carolinense (horsenettle is a highly successful weed with a gametophytic self-incompatibility (SI system. Previous studies reveal that the strength of SI in S. carolinense is a plastic trait, associated with particular S-alleles. The importance of this variation in self-fertility on the ability of horsenettle to found and establish new populations will depend, to a large extent, on the magnitude of inbreeding depression. We performed a series of greenhouse and field experiments to determine the magnitude of inbreeding depression in S. carolinense, whether inbreeding depression varies by family, and whether the estimates of inbreeding depression vary under field and greenhouse conditions. We performed a series of controlled self- and cross-pollinations on 16 genets collected from a large population in Pennsylvania to obtain progeny with different levels of inbreeding. We grew the selfed and outcrossed progeny in the greenhouse and under field conditions and recorded various measures of growth and reproductive output. Results In the greenhouse study we found (1 a reduction in flower, fruit and seed production per fruit in inbred (selfed progeny when compared to outbred (outcrossed progeny; (2 a reduction in growth of resprouts obtained from rhizome cuttings of selfed progeny; and (3 an increase in the ability to self-fertilize in the selfed progeny. In the field, we found that (1 outcrossed progeny produced more leaves than their selfed siblings; (2 herbivory seems to add little to inbreeding depression; and (3 outcrossed plants grew faster and were able to set more fruits than selfed plants. Conclusion Solanum carolinense experiences low levels of inbreeding depression under greenhouse conditions and slightly more inbreeding depression under our field conditions. The combined effects of low levels of inbreeding depression and plasticity in the strength of SI suggest that the production of selfed progeny may play an

    The authors conducted 2 studies of 9th-grade Israeli adolescents (169 in Study 1, 156 in Study 2) to compare the parenting practices of conditional positive regard, conditional negative regard, and autonomy support using data from multiple reporters. Two socialization domains were studied: emotion control and academics. Results were consistent with the self-determination theory model of internalization, which posits that (a) conditional negative regard predicts feelings of resentment toward parents, which then predict dysregulation of negative emotions and academic disengagement; (b) conditional positive regard predicts feelings of internal compulsion, which then predict suppressive regulation of negative emotions and grade-focused academic engagement; and (c) autonomy support predicts sense of choice, which then predicts integrated regulation of negative emotions and interest-focused academic engagement. These findings suggest that even parents' use of conditional positive regard as a socialization practice has adverse emotional and academic consequences, relative to autonomy support.

    The number of women entering medicine has increased significantly, yet women are still under-represented at senior levels in academic medicine. To support the gender equality action plan at one School of Medicine, this study sought to (1) identify the range of viewpoints held by staff on how to address gender inequality and (2) identify attitudinal barriers to change. Q methodology. 50 potential interventions representing good practice or positive action, and addressing cultural, organisational and individual barriers to gender equality, were ranked by participants according to their perception of priority. The School of Medicine at the University of Leeds, UK. Fifty-five staff members were purposively sampled to represent gender and academic pay grade. Principal components analysis identified six competing viewpoints on how to address gender inequality. Four viewpoints favoured positive action interventions: (1) support careers of women with childcare commitments, (2) support progression of women into leadership roles rather than focus on women with children, (3) support careers of all women rather than just those aiming for leadership, and (4) drive change via high-level financial and strategic initiatives. Two viewpoints favoured good practice with no specific focus on women by (5) recognising merit irrespective of gender and (6) improving existing career development practice. No viewpoint was strongly associated with gender, pay grade or role; however, latent class analysis identified that female staff were more likely than male to prioritise the setting of equality targets. Attitudinal barriers to the setting of targets and other positive action initiatives were identified, and it was clear that not all staff supported positive action approaches. The findings and the approach have utility for those involved in gender equality work in other medical and academic institutions. However, the impact of such initiatives needs to be evaluated in the longer term.

    Problems in communication among the government, enterprise, experts and so on and the society and people, now confront us in several areas of science and technology. In order to be accepted by the society, each area of science and technology has experienced common processes such as beginnings, business, society introduction, problem renovation and maturity. Each area can be positioned based on the degree of maturity, which helps to find solutions of the problems. Arrangement and analysis of academic findings and practical cases on risk communications in nuclear energy are described. (T. Tanaka)

    Studies in the United States have shown that physicians commonly use brand names when documenting medications in an outpatient setting. However, the prevalence of prescribing and documenting brand name medication has not been assessed in a clinical teaching environment. The purpose of this study was to describe the use of generic versus brand names for a select number of pharmaceutical products in clinical documentation in a large, urban academic family practice centre. A retrospective chart review of the electronic medical records of the St. Michael's Hospital Academic Family Health Team (SMHAFHT). Data for twenty commonly prescribed medications were collected from the Cumulative Patient Profile as of August 1, 2014. Each medication name was classified as generic or trade. Associations between documentation patterns and physician characteristics were assessed. Among 9763 patients prescribed any of the twenty medications of interest, 45% of patient charts contained trade nomenclature exclusively. 32% of charts contained only generic nomenclature, and 23% contained a mix of generic and trade nomenclature. There was large variation in use of generic nomenclature amongst physicians, ranging from 19% to 93%. Trade names in clinical documentation, which likely reflect prescribing habits, continue to be used abundantly in the academic setting. This may become part of the informal curriculum, potentially facilitating undue bias in trainees. Further study is needed to determine characteristics which influence use of generic or trade nomenclature and the impact of this trend on trainees' clinical knowledge and decision-making.

    Full Text Available Academic web search engines have become central to scholarly research. While the fitness of Google Scholar for research purposes has been examined repeatedly, Microsoft Academic and Google Books have not received much attention. Recent studies have much to tell us about the coverage and utility of Google Scholar, its coverage of the sciences, and its utility for evaluating researcher impact. But other aspects have been woefully understudied, such as coverage of the arts and humanities, books, and non-Western, non-English publications. User research has also tapered off. A small number of articles hint at the opportunity for librarians to become expert advisors concerning opportunities of scholarly communication made possible or enhanced by these platforms. This article seeks to summarize research concerning Google Scholar, Google Books, and Microsoft Academic from the past three years with a mind to informing practice and setting a research agenda. Selected literature from earlier time periods is included to illuminate key findings and to help shape the proposed research agenda, especially in understudied areas.

    Studies have shown that women in emergency medicine (EM) lag behind their male counterparts in academic productivity. We compared the proportion of female attending physicians from EM academic programs to the proportion of female first or second authors of original scientific manuscripts and case reports from four major EM journals in a single year. We used a retrospective cross-sectional design. Original scientific manuscripts and case reports from four major EM journals published in 2005: Academic Emergency Medicine, Annals of Emergency Medicine, American Journal of Emergency Medicine, and Journal of Emergency Medicine were reviewed to determine genders of first and second authors. The proportion of female first or second authorship was then compared to the proportion of female EM attending physicians from 134 academic EM programs in the United States. Data were analyzed using Pearson's chi-squared and Clopper-Pearson binomial confidence intervals as appropriate. A p-value of ≤ 0.05 was considered significant. The percentage of female faculty; 940/3571 (26.32%, 95% confidence interval [CI] 24.9-27.8%) vs. the percentage of female first or second authorship 289/1123 (25.73%, 95% CI 23.3-28.4%) was not statistically significant (p = 0.562). There was no difference in the proportion of male and female authors with multiple manuscripts (p = 0.889). As measured by first and second authorship, there was no discrepancy between the proportion of female EM faculty and the proportion of female authorship in EM literature from 2005.

Analysis of conditional lethal effects can reveal some of the loci that are sensitive to inbreeding. We performed a QTL (quantitative trait locus) mapping study...

  4. The Self-Regulation Effect of Fertility Status on Inbreeding Aversion: When Fertile, Disgust Increases more in Response to Descriptions of One's Own than of Others' Inbreeding

    Full Text Available The ovulatory shift modulates emotions related to female sexuality. Because fertility status only affects the individual's own opportunity cost, the adaptive value of this shift is expected to stem from self-regulation. To test this assumption we asked women to contemplate various inbreeding descriptions: 1 they themselves having sex with male relatives; 2 their sister having sex with their common male relatives; and 3 an unrelated woman having sex with her male relatives (in 1, but not 2 and 3, negative fitness consequences are affected by the participant's fertility. We dichotomized the dependent variable disgust (ceiling vs. non-ceiling and analyzed the interaction between fertility status and description type. The ovulatory shift was stronger in descriptions where they themselves were described as engaging in inbreeding. A smaller increase was also found in reactions to others engaging in inbreeding. We explain the latter effect as due to self-reflection.

    Full Text Available This paper describes a new social networking site, Cloudworks, which has been developed to enable discussion and sharing of learning and teaching ideas/designs and to promote reflective academic practice. The site aims to foster new forms of social and participatory practices (peer critiquing, sharing, user-generated content, aggregation, and personalisation within an educational context. One of the key challenges in the development of the site has been to understand the user interactions and the changing patterns of user behaviour as it evolves. The paper explores the extent to which four frameworks that have been used in researching networked learning contexts can provide insights into the patterns of user behaviour that we see in Cloudworks. The paper considers this within the current debate about the new types of interactions, networking, and community being observed as users adapt to and appropriate new technologies.

    Using data from parish records from 1712 to 1982 in a Spanish Pyrenean village, Ansó, the effects of the raw nuptiality, the types of consanguineous marriages and the rate and evolution of inbreeding on the mating structure have been studied. This structure has been modified in the course of time mostly through the secular variations in the frequency of consanguineous marriages. Recent inbreeding decrease in Ansó is related to the population diminution and cultural changes associated with isolate breakdown.

    The research was conducted to evaluate the performance of S1 lines for inbreeding depression regarding different parameters, using maize variety Azam. The maize variety was self-pollinated for one generation in spring season and in the next sowing season 99 S1 lines obtained from selfing was sown with a parental line. Days to silking, pollen-shedding, plant height , ear-height, ear-length, ear-diameter, number of ears/row, kernel rows/ear and 100 kernel weight showed inbreeding depression with varying degrees while yield kg/ha showed severe inbreeding depression with an average of 362.08 kg/ha. Average value of inbreeding depression for days to silking and pollen-shedding was calculated as 2.02 and 2.21 days, respectively. Average values of inbreeding depression for plant height and ear-height were recorded as 21.50 cm and 4.87 cm, respectively. While, for earlength, ear-diameter, number of ears/row, kernel rows/ear and 100 grain weight, the average value of inbreeding depression was recorded as 1.80 cm, 0.2 cm, 2.5, 2.11 and 3.89 g, respectively. Grain yield was positively and significantly correlated with plant height, ear height and yield components. Maturity traits were positively and significantly linked with each other. It is concluded that by subjecting the maize to self-pollination nearly all the lines were affected; however, some lines were affected severely and others tolerated inbreeding to some extent. The lines showing tolerance against inbreeding depression was selected for further maize breeding. (author)

  8. Better Fitness in Captive Cuvier's Gazelle despite Inbreeding Increase: Evidence of Purging?

    Directory of Open Access Journals (Sweden)

    Eulalia Moreno

    Full Text Available Captive breeding of endangered species often aims at preserving genetic diversity and to avoid the harmful effects of inbreeding. However, deleterious alleles causing inbreeding depression can be purged when inbreeding persists over several generations. Despite its great importance both for evolutionary biology and for captive breeding programmes, few studies have addressed whether and to which extent purging may occur. Here we undertake a longitudinal study with the largest captive population of Cuvier's gazelle managed under a European Endangered Species Programme since 1975. Previous results in this population have shown that highly inbred mothers tend to produce more daughters, and this fact was used in 2006 to reach a more appropriate sex-ratio in this polygynous species by changing the pairing strategy (i.e., pairing some inbred females instead of keeping them as surplus individuals in the population. Here, by using studbook data we explore whether purging has occurred in the population by investigating whether after the change in pairing strategy a inbreeding and homozygosity increased at the population level, b fitness (survival increased, and c the relationship between inbreeding and juvenile survival, was positive. Consistent with the existence of purging, we found an increase in inbreeding coefficients, homozygosity and juvenile survival. In addition, we showed that in the course of the breeding programme the relationship between inbreeding and juvenile survival was not uniform but rather changed over time: it was negative in the early years, flat in the middle years and positive after the change in pairing strategy. We highlight that by allowing inbred individuals to mate in captive stocks we may favour sex-ratio bias towards females, a desirable managing strategy to reduce the surplus of males that force most zoos to use ethical culling and euthanizing management tools. We discuss these possibilities but also acknowledge that many

A line selected for large litter size for 124 generations (H and a control line (K maintained without selection for the same number of generations were crossed (HK and used as a basis for the experiment. Within the HK cross, full sib, cousin or random mating were practised for two generations in order to create new inbreeding (IBF at a fast rate. In the first generation of systematic mating, old inbreeding was regenerated in addition to creation of new inbreeding from the mating design giving total inbreeding (IBT. The number of pups born alive (NBA and body weights of the animals were then analysed by a model including both IBT and IBF. The IBT of the dam was in the present study found to reduce the mean NBA with -0.48 (± 0.22 (p F was -0.42 (± 0.27. For the trait NBA per female mated, the effect of IBT was estimated to be -0.45 (± 0.29 per 10% increase in the inbreeding coefficient and the effect of IBF was -0.90 (± 0.37 (p F of the dam could be found on sex-ratio and body weights at three and six weeks of age in a population already adjusted for IBT.

  11. Mitigation of inbreeding while preserving genetic gain in genomic breeding programs for outbred plants.

    Heuristic genomic inbreeding controls reduce inbreeding in genomic breeding schemes without reducing genetic gain. Genomic selection is increasingly being implemented in plant breeding programs to accelerate genetic gain of economically important traits. However, it may cause significant loss of genetic diversity when compared with traditional schemes using phenotypic selection. We propose heuristic strategies to control the rate of inbreeding in outbred plants, which can be categorised into three types: controls during mate allocation, during selection, and simultaneous selection and mate allocation. The proposed mate allocation measure GminF allocates two or more parents for mating in mating groups that minimise coancestry using a genomic relationship matrix. Two types of relationship-adjusted genomic breeding values for parent selection candidates ([Formula: see text]) and potential offspring ([Formula: see text]) are devised to control inbreeding during selection and even enabling simultaneous selection and mate allocation. These strategies were tested in a case study using a simulated perennial ryegrass breeding scheme. As compared to the genomic selection scheme without controls, all proposed strategies could significantly decrease inbreeding while achieving comparable genetic gain. In particular, the scenario using [Formula: see text] in simultaneous selection and mate allocation reduced inbreeding to one-third of the original genomic selection scheme. The proposed strategies are readily applicable in any outbred plant breeding program.

    Full Text Available Pedigree records of 17250 Thalli sheep with 17030 lambings maintained at the Livestock Experiment Station, Rakh Ghulaman, Distt. Bhakkar, Pakistan during the period from 1975 to 2004 were utilized in the present study. Average values for birth weight, weights at 60 and 90 days of age, weaning weight and pre-weaning average daily gain were 4.11 ± 0.82, 11.58 ± 3.57, 14.92 ± 4.56, 18.95 ± 4.56 and 0.12 ± 0.04 kg, respectively. Coefficients of inbreeding ranged from 10.15 to 37.50 percent for 295 animals, being 1.70 percent of the flock. Inbreeding significantly (P<0.01 affected birth and 60 days weight. Birth weight and 60 days weight decreased by 0.051 and 0.048 kg for each 1 percent increase in the level of inbreeding. However, inbreeding had non significant effect on weight at 90 days of age, weaning weight and pre-weaning average daily gain. The regression values for these traits were 0.010, 0.083 and 0.105, respectively. It was concluded that inbreeding showed deleterious effects only in early stages of life but as the lambs grew older the effect of inbreeding on pre-weaning traits diminished.

    A pilot study of two academic training programs revealed concerning levels of resident burnout and psychological dysfunction. The purpose of the present study was to determine the quality of life of orthopaedic residents and faculty on a national scale and to identify risk factors for decompensation. Three hundred and eighty-four orthopaedic residents and 264 full-time orthopaedic faculty members completed a voluntary, anonymous survey consisting of three validated instruments (the Maslach Burnout Inventory, the General Health Questionnaire-12, and the Revised Dyadic Adjustment Scale) and question sets assessing demographic information, relationship issues, stress reactions/management, and work/life balance. High levels of burnout were seen in 56% of the residents and 28% of the faculty members. Burnout risk was greatest among second-postgraduate-year residents and residents in training programs with six or more residents per postgraduate year. Sixteen percent of residents and 19% of faculty members reported symptoms of psychological distress. Sleep deprivation was common among the residents and correlated positively with every distress measure. Faculty reported greater levels of stress but greater satisfaction with work and work/life balance. A number of factors, such as making time for hobbies and limiting alcohol use, correlated with decreased dysfunction for both residents and faculty. Despite reporting high levels of job satisfaction, orthopaedic residents and faculty are at risk for burnout and distress. Identification of protective factors and risk factors may provide guidance to improve the quality of life of academic orthopaedic surgeons in training and beyond.

    The purpose of this paper is to link external political strategy theory to a specific health care setting-that of the academic medical center (AMC). Political strategy encompasses those activities undertaken by AMCs to acquire, develop, and use power (clout, influence, and credibility) to gain an advantage in situations of conflict. It should be differentiated from internal politics, a topic that will not be dealt with in this review. Political strategy should also be distinguished from but not divorced from competitive strategy. As political and social action can change the competitive landscape and the rules of competition, AMCs must become adept in issues management and stakeholder management. The focus on political strategy is a reflection of the enormous changes in the external environment that have impacted AMCs in recent years. These changes have often emerged out of political and social action and they impact significantly on the organization's more traditional business strategies. We suggest that a tighter alignment between political and business strategies in the future will help ensure organizational survival and success. This article reviews the literature and theory in corporate political strategy and illustrates the application of political strategy with examples of issues and problems faced by AMCs. Models of political strategy are well crafted, and this article concludes with succinct observations on the use of political strategies to enhance the business-based strategies of AMCs. Although the focus is on AMCs, the use of political strategies is applicable to any health care institution. Copyright 2001 Academic Press.

Recently, the effects of inbreeding on reproductive traits such as sperm quality have become a subject of particular interest for conservation...... biology, evolutionary ecology, and management of captive populations. This study investigated the effects of inbreeding on sperm quality in a captive population of experimentally inbred and outbred lake trout, Salvelinus namaycush. It was found for moderately to highly inbred males (males with half......‐sib and full‐sib parents, respectively), that sperm quality traits (velocity, motility, linearity, longevity, spermatocrit and morphology) showed no apparent inbreeding depression. The apparent lack of inbreeding effects on sperm quality traits may be due to several factors including (i) no inbreeding...

    Full Text Available Abstract Background Given that no influence of inbreeding on life expectancy could be demonstrated in Irish Wolfhounds in a previous study, it was decided to test the influence of inbreeding and other parameters on fertility in this breed. Methods The study was based on all Irish Wolfhound litters registered in Sweden between 1976 and 2007 (n = 822 litters as provided by the Swedish Kennel Club (SKK and combined with a pedigree database going back to 1862. Analyses were performed using linear regression in a Generalised Linear Model and other tests in the SAS system®. Results Mean number of pups per litter was 6.01 ± 2.65, with a maximum of 13. There were no significant differences in either the number of litters or the number of pups between years of birth. Males were used for breeding at a significantly earlier age than females. Mean number of litters per parent was 2.96 ± 3.14 for males and 1.59 ± 0.87 for females. No influence of Wright's inbreeding coefficients over 5, 10, 20 and 30 generations and/or Meuwissen's inbreeding coefficients on litter size was detected. In the Generalised Linear Model, highly significant, but weak (coefficient of determination (R2 = 0.0341 influences were found for maternal age at mating as well as maternal inbreeding measured by Wright's inbreeding coefficient over 30 generations and Meuwissen's inbreeding coefficient. Paternal inbreeding coefficients over 5, 10, 20 and 30 generations and calculated after Meuwissen, as well as maternal inbreeding coefficients over 5, 10 and 20 generations did not have significant effects on litter size. Conclusion The low coefficient of determination (R2 value of the Generalised Linear Model indicates that inbreeding does not have a strong influence on fertility in Irish Wolfhounds, which is consistent with earlier results and the breed's genetic history. These results likely reflect the aforementioned genetic history and should not be extrapolated to other breeds without

    Intensive care medicine is a relatively young discipline that has rapidly grown into a full-fledged medical subspecialty. Intensivists are responsible for managing an ever-increasing number of patients with complex, life-threatening diseases. Several factors may influence their performance, including age, training, experience, workload, and socioeconomic context. The aim of this study was to examine individual- and work-related aspects of the Latin American intensivist workforce, mainly with academic appointments, which might influence the quality of care provided. In consequence, we conducted a cross-sectional study of intensivists at public and private academic and nonacademic Latin American intensive care units (ICUs) through a web-based electronic survey submitted by email. Questions about personal aspects, work-related topics, and general clinical workflow were incorporated. Our study comprised 735 survey respondents (53% return rate) with the following country-specific breakdown: Brazil (29%); Argentina (19%); Chile (17%); Uruguay (12%); Ecuador (9%); Mexico (7%); Colombia (5%); and Bolivia, Peru, Guatemala, and Paraguay combined (2%). Latin American intensivists were predominantly male (68%) young adults (median age, 40 [IQR, 35-48] years) with a median clinical ICU experience of 10 (IQR, 5-20) years. The median weekly workload was 60 (IQR, 47-70) h. ICU formal training was between 2 and 4 years. Only 63% of academic ICUs performed multidisciplinary rounds. Most intensivists (85%) reported adequate conditions to manage patients with septic shock in their units. Unsatisfactory conditions were attributed to insufficient technology (11%), laboratory support (5%), imaging resources (5%), and drug shortages (5%). Seventy percent of intensivists participated in research, and 54% read scientific studies regularly, whereas 32% read no more than one scientific study per month. Research grants and pharmaceutical sponsorship are unusual funding sources in Latin

    The decision of radiation oncology residents to pursue academic versus private practice careers plays a central role in shaping the present and future of the field, but factors that are potentially predictive of this decision are lacking. This study was performed to examine the role of several factors publicly available before residency on postresidency career choice, including preresidency peer-reviewed publications (PRPs), which have been associated with resident career choice in comparably competitive subspecialties such as neurosurgery. Using a combination of Internet searches, telephone interviews, and the 2015 Association of Residents in Radiation Oncology directory, a list of 2016 radiation oncology resident graduates was compiled, along with their postresidency career choice. PRP was defined as the number of PubMed publications encompassing the end of the calendar year (2010) in which residency applications were due; this number was then correlated with career choice. A total of 163 residents from 76 Accreditation Council for Graduate Medical Education-certified programs were examined: 78% were male, 22% were MDs/PhDs, and 79 graduates (48%) chose academic careers. Fifty-two percent of graduates had at least 1 PRP at the time of application to radiation oncology residency; 35% had more than 1 PRP. Regarding career choice, the difference between 0 and 1+ PRP was statistically significant (odds ratio, 3.3; P 1 PRP. Sex, PhD, or non-PhD dual degree status were not associated with career choice. Radiation oncology residency graduates with 1 or more PRPs at the time of residency application were roughly 2 times more likely to choose an academic career as their initial career choice than graduates with no preresidency PRPs. This information may prove useful to medical students, medical school advisors, and residency program directors and deserves further prospective investigation.

    Full Text Available During the past few years, there have been some changes on traditional training methodologies in the world, specially, in elementary schools. Many schools have decided to perform their assessments in elementary schools based on qualitative methods compared with traditional quantitative techniques. This paper performs an empirical investigation to find out whether the new evaluation technique has been able to improve student teacher’s cognitive abilities and skills on evaluation of academic achievement practices. These student-teacher people taught at elementary schools while they also were studying at university. There are two types of questionnaires: The first one measures cognitive capabilities in four categories including levels of learning and educational objectives, designing paper and pencil test, functional test design and analysis and interpretation of results. The second test is associated with measuring functional skills in the evaluation of academic progress. The information were analyzed based on t-student test as well as two-way analysis of variance. The result of t-statistics was significant only for the last item, analysis and interpretation. In addition, the results of ANOVA test have indicated that there were some differences on cognitive capabilities between two methods of assessments but gender did not make any meaningful difference on functional skills.

    A correlation exists between people who engage in academic dishonesty as students and unethical behaviors later as professionals. Academic dishonesty has been assessed among medical students, but not among general surgery residents. We sought to describe the attitudes of general surgery residents with regard to ethical practices in test taking. A survey with 4 scenarios describing activities related to examination taking that may or may not be considered unethical was administered. Participants were asked about participation in the activities-either personally or any knowledge of others-and whether the activities were unethical. Fifty-seven of 62 residents (92%) participated. For each scenario, >70% indicated that neither they nor anyone else they knew had participated in the activities. Behaviors deemed unethical included memorizing or using memorized questions to prepare for future tests (52%), selling questions for financial gain (90%), and purchasing previously used questions (57%). No difference in attitudes was seen among incoming interns, junior-level (postgraduate year [PGY]1-3), or senior-level (PGY4-6) residents. Overall, general surgery residents indicated that they had not participated in activities they felt to be unethical. Defining what is unethical was less clear.

    Through the collection of Practice of acupuncture and moxibustion written by CHEN Jingwen, the acupuncture master in the Republic of China, the academic characteristics on acupuncture and moxibusiton were analyzed. The literature comparison method was adopted to compare the works of LUO Zhaoju, ZENG Tianzhi and LI Wenxian, etc. at the same period. It was discovered that CHEN Jingwen was the medical master who systematicly brought up the theory of acupoint properties earlier in the modern times. Classifying drugs based on acupoints was his academic feature. Additionally, the compatibility therapy of Chinese medicine was introduced to explain the essential ideas on the acupoints combination. The treatment was determined on the basis of zangxiang theory and the reinforcing and reducing therapy of acupuncture was emphasized in the determination of treatment and prescription. CHEN Jingwen's theory of acupoint property had been stressed and spread among the medical scholars in the Republic of China and he had made the beneficial exploration for the development of modern acupuncture and moxibustion therapy.

    2009-01-01

    A digital repository is a web accessible database, aimed at preserving the research material of an institution or scientific community. A digital repository serves as a tool for dissemination of research material and can increase the impact of the research by making it freely accessible. Digital repositories are often mentioned as a possible aid in relation to the Open Access debate; how research material should be freely accessible to anyone, anywhere at any time. However, for a digital repository to fully unleash its potential as a crucial component of Open Access, it is reliant on the ability to successfully collect and organize content. To a large extent this involves initiating self-archiving of research material by scientists throughout the academic world. This is not a trivial task, and many current repositories are inadequate in this respect, remaining empty, unvisited shelves. This thesis explores best practices for content recruitment to digital repositories, through the review of literature, and an...

    Full Text Available Introduction The mating of related individuals produces an inbred offspring and leads to an increased homozygosity in the progeny, genetic variance decrease within families and increase between families. The ration of homozygosity for individuals was calculated by inbreeding coefficient. Inbred individuals may carry two alleles at a locus that are replicated from one gene in the previous generations, called identical by descent. The inbreeding coefficient should be monitored in a breeding program, since it plays an important role at decreasing of homeostasis, performance, reproduction and viability. The trend of inbreeding is an indicator for determining of inbreeding level in the herd. Inbreeding affects both phenotypic means of traits and genetic variances within population, thus it is an important factor for delimitations of genetic progress in a population. Reports showed an inbreeding increase led to decrease of phenotypic value in some of the productive and reproductive traits. Materials and Methods In the current study, the pedigree data of 14030 and 6215 records of Baluchi and Iranblack lambs that collected from 1984 to 2011 at the Abbasabad Sheep Breeding Station in Mashhad, Iran, 3588 records of Makoei lambs that collected from 1994 to 2011 at the Makoei sheep breeding station and 6140, records of Zandi lambs that collected from 1991 to 2011 at the Khejir Sheep Breeding Station in Tehran, Iran were used to estimating the inbreeding coefficient and its effects on lamb survival in these breeds. Lamb survival trait was scored as 1 and 0 for lamb surviving and not surviving at weaning weight, respectively. Inbreeding coefficient was estimated by relationship matrix algorithm (A=TDT' methodology using the CFC software program. Effects of inbreeding coefficient on lamb survival were estimated by restricted maximum likelihood (REML method under 12 different animal models using ASReml 3.0 computer programme.

    Full Text Available The monitoring process is based on a strategy which propitiates interdisciplinary and gathering theory and practice, apart from teaching assistance, easing and increasing students learning, awakening the academic discipline’s interest and importance. The developed task held over the course of two academic consecutive semesters in 2014 on Biology Science Major at Federal University of Uberlândia had as a goal the use of diverse methodological alternatives in Biochemistry such as: basic bibliography’s comprehension support, approaching and integration mechanism from the content to learner’s reality, meetings to feedback pre-assessment valuation, constructive debates, conceptual issues and questioning in order to clarify any doubts from the content discussed, besides the supervisor’s assistance in practical classes. The resources used to this approach were the student’s analysis to monitoring, their performances on the subject and the approval, retention and evasion levels at the end of the semesters. The obtained results have shown a high level of approval on both semesters, combined to decreasing level of evasion and retention. It was possible to clarify that on the discipline´s development the increasing search for monitoring as much as the complexity´s raise from some contents as the interest and curiosity in knowing certain methods used in monitoring. Improving on student´s performance and arguing on written evaluation also were noticed. The obtained results also proved that diverse methodological alternatives in Biochemistry are potential strategies in maximizing the approval levels in that discipline and bring the student close to the content in a dynamic way, supporting to a better knowledge development in the subject. Monitoring can also be a mean to stimulate the interest in teaching.

    Full Text Available BACKGROUND: Studies that use electronic health databases as research material are getting popular but the influence of a single electronic health database had not been well investigated yet. The United Kingdom's General Practice Research Database (GPRD is one of the few electronic health databases publicly available to academic researchers. This study analyzed studies that used GPRD to demonstrate the scientific production and academic impact by a single public health database. METHODOLOGY AND FINDINGS: A total of 749 studies published between 1995 and 2009 with 'General Practice Research Database' as their topics, defined as GPRD studies, were extracted from Web of Science. By the end of 2009, the GPRD had attracted 1251 authors from 22 countries and been used extensively in 749 studies published in 193 journals across 58 study fields. Each GPRD study was cited 2.7 times by successive studies. Moreover, the total number of GPRD studies increased rapidly, and it is expected to reach 1500 by 2015, twice the number accumulated till the end of 2009. Since 17 of the most prolific authors (1.4% of all authors contributed nearly half (47.9% of GPRD studies, success in conducting GPRD studies may accumulate. The GPRD was used mainly in, but not limited to, the three study fields of "Pharmacology and Pharmacy", "General and Internal Medicine", and "Public, Environmental and Occupational Health". The UK and United States were the two most active regions of GPRD studies. One-third of GRPD studies were internationally co-authored. CONCLUSIONS: A public electronic health database such as the GPRD will promote scientific production in many ways. Data owners of electronic health databases at a national level should consider how to reduce access barriers and to make data more available for research.

    Full Text Available We intended to identify the features and pedagogical trends of the school practices proposed and implemented in thesis and dissertations directed to science education at elementary school level from 1972 to 2005. Thirty studies were analysed regarding the teaching methodology, instructional resources, teacher-student relationships, evaluation, theoretical framework, and educational model (traditional, rediscovery, constructivist, technicist, STS, socio-cultural. We found that the constructivist model was dominant (63%, followed by the socio-cultural (20% and the rediscovery one (10%, and that the pedagogical practices were elaborated by researchers, applied by teachers and performed by students, showing a vertical hierarchy between university and school. However, the implemented practices (actual level usually were quite distant from the researchers discourse (proposed level. We also observed that the researchers didn’t find many difficulties in designing and applying a pedagogical proposal with innovative features, but to make changes in the school and social relations, as well as in the evaluation practices, is a barrier difficult to overcome.

    To measure the effect of electronic health record (EHR) implementation on productivity and efficiency in the pediatric ophthalmology division at an academic medical center. Four established providers were selected from the pediatric ophthalmology division at the Oregon Health & Science University Casey Eye Institute. Clinical volume was compared before and after EHR implementation for each provider. Time elapsed from chart open to completion (OTC time) and the proportion of charts completed during business hours were monitored for 3 years following implementation. Overall there was an 11% decrease in clinical volume following EHR implementation, which was not statistically significant (P = 0.18). The mean OTC time ranged from 5.5 to 28.3 hours among providers in this study, and trends over time were variable among the four providers. Forty-four percent of all charts were closed outside normal business hours (30% on weekdays, 14% on weekends). EHR implementation was associated with a negative impact on productivity and efficiency in our pediatric ophthalmology division.

  16. Categories of difference in science and policy: Reflections on academic practices, conceptualizations and knowledge production

    2012-09-01

    Full Text Available Categories of difference have a crucial position in academic research as well as policy-making. They serve to distinguish and differentiate between groups in society. They can appear in the shape of crude dichotomies or in complex and sophisticated forms resting on constructivist and intersectionalist perspectives. Nevertheless, using categories of difference also creates something into existence and there may be implications through the particular application of specific categories. This article reflects on how categories of difference are constructed and employed in research, legislation and policy discourse. By looking at different approaches used by qualitative and quantitative researchers, as well as at how specific concepts enter policy-making and legislation, I want to address a number of questions about how we as researchers understand and work with categories of differences. The article will mainly consist of a theoretical discussion, but will use two main empirical examples of race and religion. The article aims to provide tentative answers about what the consequences of particular uses of categories and concepts could be.

    Academic medical centers (AMCs) could advance the science of health care delivery, improve patient safety and quality improvement, and enhance value, but many centers have fragmented efforts with little accountability. Johns Hopkins Medicine, the AMC under which the Johns Hopkins University School of Medicine and the Johns Hopkins Health System are organized, experienced similar challenges, with operational patient safety and quality leadership separate from safety and quality-related research efforts. To unite efforts and establish accountability, the Armstrong Institute for Patient Safety and Quality was created in 2011.The authors describe the development, purpose, governance, function, and challenges of the institute to help other AMCs replicate it and accelerate safety and quality improvement. The purpose is to partner with patients, their loved ones, and all interested parties to end preventable harm, continuously improve patient outcomes and experience, and eliminate waste in health care. A governance structure was created, with care mapped into seven categories, to oversee the quality and safety of all patients treated at a Johns Hopkins Medicine entity. The governance has a Patient Safety and Quality Board Committee that sets strategic goals, and the institute communicates these goals throughout the health system and supports personnel in meeting these goals. The institute is organized into 13 functional councils reflecting their behaviors and purpose. The institute works daily to build the capacity of clinicians trained in safety and quality through established programs, advance improvement science, and implement and evaluate interventions to improve the quality of care and safety of patients.

    Inbreeding and loss of genetic variation are considered to be major threats to small and endangered populations. The reduction of fitness due to inbreeding is believed to be more severe under stressful environmental conditions. We generated nine strains of the ecotoxicological model organism Chironomus riparius of different inbreeding levels in order to test the hypothesis that the inbreeding level and thus the degree of genome-wide homozygosity influences the life-history under cadmium exposure. Therefore, midge populations were exposed to a gradient of sediment-bound cadmium. The level of genetic variation in the used strains was assessed using microsatellite markers. In the life-cycle tests, inbreeding reduced fitness within C. riparius populations both under control and stressed conditions. However, differences between genetically diverse and impoverished strains were greatest at high cadmium exposure. Overall, inbreeding effects were not only dependent on cadmium concentrations in the sediment, but also on the life-history trait investigated. While some parameters where only affected by inbreeding, others were altered by both, inbreeding and cadmium. For the larval developmental time, a significant interaction was found between inbreeding and cadmium stress. While all strains showed a similar developmental time under control conditions, high rates of inbreeding led to a significantly delayed emergence time under high cadmium concentrations, resulting in longer generation periods and reduced population growth rates as population-relevant effects. The results show, that bioassays with C. riparius are affected by the level of inbreeding within Chironomus test strains. Pollution stress is therefore likely to affect the survival of rare and endangered populations more severe than that of large and genetically diverse ones

    Mifepristone offers internal medicine doctors the opportunity to greatly expand access to abortion for their patients. Almost 70% of pregnancy terminations, however, still occur in specialized clinics. No studies have examined the preferences of Internal Medicine patients specifically. Determine whether patient preference is a reason for the limited uptake of medication abortion among internal medicine physicians. Women aged 18-45 recruited from the waiting room in an urban academic internal medicine clinic. A semi-structured questionnaire was used to determine risk of unintended pregnancy and attitudes toward abortion. Support for provision of medication abortion in the internal medicine clinic was assessed with a yes/no question, followed by the open-ended question, "Why do you think this clinic should or should not offer medication abortion?" Subjects were asked whether it was very important, somewhat important, or not important for the internal medicine clinic to provide medication abortion. Of 102 women who met inclusion criteria, 90 completed the survey, yielding a response rate of 88%. Twenty-two percent were at risk of unintended pregnancy. 46.7% had had at least one lifetime abortion. Among those who would consider having an abortion, 67.7% responded yes to the question, "Do you think this clinic should offer medication abortions?" and 83.9% stated that it was "very important" or "somewhat important" to offer this service. Of women open to having an abortion, 87.1% stated that they would be interested in receiving a medication abortion from their primary care doctor. A clinically significant proportion of women in this urban internal medicine clinic were at risk of unintended pregnancy. Among those open to having an abortion, a wide majority would consider receiving it from their internal medicine doctor. The provision of medication abortion by internal medicine physicians has the potential to greatly expand abortion access for women.

    This study assesses the prevalence of use of the most commonly used social media sites among private radiology groups (PRGs) and academic radiology departments (ARDs). The 50 largest PRGs and the 50 ARDs with the highest level of funding from the National Institutes of Health were assessed for presence of a radiology-specific social media account on Facebook, Twitter, Instagram, Pinterest, YouTube, and LinkedIn. Measures of organizational activity and end-user activity were collected, including the number of posts and followers, as appropriate; between-group comparisons were performed. PRGs adopted Facebook 12 months earlier (P = .02) and Twitter 18 months earlier (P = .02) than did ARDs. A total of 76% of PRGs maintained ≥1 account on the social media sites included in the study, compared with 28% of ARDs (P Instagram, 2%. The prevalence of radiology-specific social media accounts for ARDs was: Facebook, 18%; LinkedIn, 0%; Twitter, 24%; YouTube, 6%; Pinterest, 0%; and Instagram, 0%. There was no significant difference between ARDs and PRGs in measures of end-user or organizational activity on Facebook or Twitter. Use of social media in health care is emerging as mainstream, with PRGs being early adopters of Facebook and Twitter in comparison with ARDs. Competitive environments and institutional policies may be strong factors that influence how social media is used by radiologists at the group and department levels.

    Differences in the initial management of pediatric eosinophilic esophagitis (EoE) by practice setting have not been well characterized. We aimed to characterize these differences for sites in the Carolinas EoE Collaborative (CEoEC), a multicenter network of academic and community practices. We performed a retrospective cohort study of pediatric EoE patients at five CEoEC sites: University of North Carolina (UNC) Hospital, Charlotte Asthma and Allergy Specialists, Greenville Health Systems, Wake Forest Baptist Medical Center, and the Medical University of South Carolina Hospital. Cases of EoE were defined by consensus guidelines. Data were extracted from electronic medical records. We tested for differences among sites and used a multinomial model (polytomous regression) to assess associations between treatment and site, adjusting on patient factors. We identified 464 children with EoE across the CEoEC sites. The median age was highest at Wake Forest (11.4 years), the median eosinophil count was highest at UNC (69 eos/hpf), and UNC had the most male patients (82%). UNC used topical steroids for initial treatment in 86% of cases, compared with <1% in Greenville ( P < 0.01). Greenville used dietary elimination more frequently than UNC (81% vs 2%, P < 0.01). Differences in treatment approach held after adjusting for potential baseline confounders. There was no significant association between patient factors and initial treatment approach. Significant differences in EoE patient factors and treatment approaches were identified across CEoEC sites and were not explained by patient or practice factors. This suggests that institutional or provider preferences drive initial treatment approaches, and that more data are needed to drive best practice decisions.

  3. Balancing Bologna: opportunities for university teaching that integrates academic and practical learning outcomes

    2014-05-01

    In the course of the Bologna Process, the quality of university teaching has become more prominent in the discourse on higher education. More attention is now paid to didactics and methods and learner-oriented modes of teaching are introduced. The application of knowledge, practical skills and in consequence the employability of university graduates have become requirements for university teaching. Yet, the lecture-style approach still dominates European universities, although empirical evidence confirms that student-centred, interdisciplinary and experiential learning is more effective. Referring to the learning taxonomy introduced by Bloom, we argue that standard approaches rarely move beyond the learning level of comprehension and fail to reach the levels of application, analysis, synthesis and evaluation. Considering the rapid changes and multiple challenges society faces today, responsible practitioners and scientists who can improve the current management of natural resources are urgently needed. Universities are expected to equip their graduates with the necessary skills to reflect and evaluate their actions when addressing 'real world' problems in order to improve impact and relevance of their work. Higher education thus faces the challenge of providing multi-level learning opportunities for students with diverse practical and theoretical learning needs. In this study, we reflect on three cases of university teaching attempting to bridge theory and practice and based on the principles of systemic, problem based learning. The described courses focus on organic farming, rural development and landscape planning and take place in Uganda, Nicaragua and Italy. We show that being part of a real-world community of stakeholders requires hands-on learning and the reflection and evaluation of actions. This prepares students in a more effective and realistic way for their future roles as responsible decision makers in complex social, economic and ecological systems. We

  4. How do veterinary students' motivation and study practices relate to academic success?

    2011-01-01

    The aim of the present study was to explore the factors associated with veterinary students' study success. All veterinary students who began their studies at the University of Helsinki in 2005 participated in this qualitative longitudinal study (N=52). The data consisted of assignments that the students completed at the beginning of their studies and again after three years of studying. The focus was on differences in motivation and study practices as well as possible changes in these over the three-year period. The students were divided into three groups according to their study success (grade point average and study progress). These groups were compared according to group-level differences in the categorized data. The most successful students already described themselves using more positive words than other students at the beginning of their veterinary studies. In addition, they seemed more adaptive in relation to the study's demands. However, there were drops in both the most and least successful students' motivation during their studies. The findings suggest that it is possible to predict forthcoming study problems by analyzing students' study practices and their own descriptions of themselves as learners. In addition, the results show that veterinary students' high motivation cannot be taken for granted. The comparative and longitudinal perspective of the present study can be useful in the development of curricula and in student support.

The lowest measurements of metabolic rate in our study are always associated with the low activity period of the diurnal cycle and these measurements therefore serve as good estimates...... of standard metabolic rate. Due to the potentially added costs of genetic stress in inbred lines we hypothesized that inbred individuals have increased metabolic rate compared to outbred controls and that this is more pronounced at stressful temperatures due to synergistic inbreeding by environment...... interactions. Contrary to our hypothesis we found no significant difference in metabolic rate between inbred and outbred lines and no interaction between inbreeding and temperature. Inbreeding however effected the variance; the variance in metabolic rate was higher between the inbred lines compared...

    Full Text Available An observed case of inbreeding in a pack ot wild dogs Lycaon pictus in the Kruger National Park, Republic of South Africa, provides evidence for the phenomenon of dominance reversal in this species. This is believed to be the first recorded instance of inbreeding in Lycaon. Emigration of subordinate females from established packs of wild dogs has been documented in the Serengeti National Park and Ngorongoro Conservation Area in northern Tanzania, as well as in the Kruger National Park. However, the newly subordinate (ex-dominant female in the pack in which inbreeding has occurred has not emigrated in the 16 months since the change in her status. A possible explanation for this behaviour is given. As a result of this reversal, the pack contains at least two females capable of breeding, the subordinate of which is at least two years older than the dominant. This is considered the first record of such a breeding structure in Lycaon.

    Inbreeding depression is the reduction in fitness caused by mating between related individuals. Inbreeding is expected to cause a reduction in offspring fitness when the offspring themselves are inbred, but outbred individuals may also suffer a reduction in fitness when they depend on care from inbred parents. At present, little is known about the significance of such intergenerational effects of inbreeding. Here, we report two experiments on the burying beetle Nicrophorus vespilloides, an insect with elaborate parental care, in which we investigated inbreeding depression in offspring when either the offspring themselves or their parents were inbred. We found substantial inbreeding depression when offspring were inbred, including reductions in hatching success of inbred eggs and survival of inbred offspring. We also found substantial inbreeding depression when parents were inbred, including reductions in hatching success of eggs produced by inbred parents and survival of outbred offspring that received care from inbred parents. Our results suggest that intergenerational effects of inbreeding can have substantial fitness costs to offspring, and that future studies need to incorporate such costs to obtain accurate estimates of inbreeding depression. © 2013 The Authors.

    Navigating the regulations to protect human subjects and private health information for Doctor of Nursing Practice (DNP) projects can be a formidable task for students, faculty, and the institutional review board (IRB). Key stakeholders from the University of Iowa College of Nursing and the Human Subjects Office developed a standardized process for DNP students to follow, using a decision algorithm, a student orientation to the human subjects review process conducted by faculty and IRB chairs and staff, and a brief Human Subjects Research Determination form. Over 2 years, 109 students completed the process, and 96.3% of their projects were deemed not to be human subjects research. Every student submitted documentation of adherence to the standardized process. Less time was spent by students, faculty, and the IRB in preparing and processing review requests. The interprofessional collaboration resulted in a streamlined process for the timely review of DNP projects. Copyright 2015, SLACK Incorporated.

    Full Text Available The reflections contained in this essay seek to the call attention of professionals, professors and students of Social Work to the importance of research in the various contexts of activity in this field, despite the challenges and difficulties presented in its realization. It offers possibilities for conducting research from a critical professional intervention, in keeping with the concrete reality - the context of professional practice. It also highlights the importance for the preparation of a history of Social Work based on theoretical-methodological postures that consider the wealth, complexity and essence of reality, breaking with the 'pseudoconcreticity', with the utilitarian, manipulative praxis that is constructed in the dimension of a 'common consciousness'. Despite the importance attributed to research, it sought to avoid separating it from human-social reality, given that it is in this context that research acquires meaning, becomes accepted and considers the needs of Social Work as a historic profession.

    The Black Forest Draught horse (BFDH) is an endangered German coldblood breed with its origin in the area of the Black Forest in South Germany. In this retrospective study, the influence of the inbreeding coefficient on foaling rates was investigated using records from ten breeding seasons. Due to the small population size of BFDH, the level of inbreeding is increasing and may have an effect on foaling rates.The data of the present study included all coverings reported for 1024 BFDH mares in the years 2001-2009. These mares were covered by 32 BFDH stallions from the State Stud Marbach. Data from 4534 estrus cycles was used to calculate per cycle foaling rate (CFR). Pedigree data contained all studbook data up to the foundation of the breed as early as 1836. The level of inbreeding of the mare, stallion and expected foal along with other systematic effects on CFR were analysed using a generalized linear mixed model approach. Stallion was employed as a random effect. Systematic fixed effects were month of mating, mating type, age of the mare and stallion, reproductive status of the mare and stallion line of the mare. Inbreeding coefficients of the stallion, mare and expected foal were modelled as linear covariates. The average CFR was 40.9%. The mean inbreeding coefficients of the mares, stallions and expected foals were 7.46, 7.70 and 9.66%. Mating type, age of the mare, reproductive status of the mare and stallion line of the mare had a significant effect. The results showed that the mating type, stallion line of the mare, sire, age and reproductive status of the mare exerted the largest influences on CFR in BFDH. Inbreeding coefficients of the stallion, mare and expected foal were not significantly related with CFR.

    Due to consistent increases of inbreeding of on average 0.95% per generation in layer populations, selection tools should consider both genetic gain and genetic relationships in the long term. The optimum genetic contribution theory using official estimated breeding values for egg production was applied for 3 different lines of a layer breeding program to find the optimal allocations of hens and sires. Constraints in different scenarios encompassed restrictions related to additive genetic relationships, the increase of inbreeding, the number of selected sires and hens, and the number of selected offspring per mating. All these constraints enabled higher genetic gain up to 10.9% at the same level of additive genetic relationships or in lower relationships at the same gain when compared with conventional selection schemes ignoring relationships. Increases of inbreeding and genetic gain were associated with the number of selected sires. For the lowest level of the allowed average relationship at 10%, the optimal number of sires was 70 and the estimated breeding value for egg production of the selected group was 127.9. At the highest relationship constraint (16%), the optimal number of sires decreased to 15, and the average genetic value increased to 139.7. Contributions from selected sires and hens were used to develop specific mating plans to minimize inbreeding in the following generation by applying a simulated annealing algorithm. The additional reduction of average additive genetic relationships for matings was up to 44.9%. An innovative deterministic approach to estimate kinship coefficients between and within defined selection groups based on gene flow theory was applied to compare increases of inbreeding from random matings with layer populations undergoing selection. Large differences in rates of inbreeding were found, and they underline the necessity to establish selection tools controlling long-term relationships. Furthermore, it was suggested to use

    Aim of study Person-centered medicine (PCM) with its focus on humanistic-biographical-oriented medicine and integrated, positive-salutogenic health is a central aspect in the patient-physician relationship in general practice. The objective of this analysis is to assess the prevalence and type of research project in academic institutions of general practice in Germany (Ger) and Austria (At) and the thematic priorities of the projects in the areas PCM, health promotion (HP), prevention (PRE) and conventional medicine (CM). Methods A search was conducted (September-December 2015) on the websites of 30 institutes and divisions of general medicine for their current research projects. The retrieved projects were assigned to five categories: PCM, HP, PRE, CM and others. Subsequently, we identified the targeted patient groups of the projects as well as the thematic focus in the categories PCM, HP, PRE and CM with focus on PCM and HP. Results 541 research projects were identified, 452 in Germany and 89 in Austria. Research projects were only included if they were explicitly indicated as research-oriented. Seventy projects addressed PCM aspects, 15 projects HP aspects, 32 projects PRE aspects and 396 projects CM aspects. The most frequently target groups in the categories PCM (24 of 70) and HP (7 of 15) were chronically ill patients. The most common thematic focus in PCM was communication (13 of 70) and in HP, physical activity (6 of 15). Conclusion The vast majority of research projects investigated conventional medical topics. The percentage of research activities in the field of PCM (13%) or PCM including HP (16%) in Ger and At is below the European average of 20%. From our point of view, PCM and HP need to be implemented to a greater extent in general practice. © Georg Thieme Verlag KG Stuttgart · New York.

    While there is growing awareness of the risk of harm in ambulatory health care, most patient safety efforts have focused on the inpatient setting. The Comprehensive Unit-based Safety Program (CUSP) has been an integral part of highly successful safety efforts in inpatient settings. In 2014 CUSP was implemented in an academic primary care practice. As part of CUSP implementation, staff and clinicians underwent training on the science of safety and completed a two-question safety assessment survey to identify safety concerns in the practice. The concerns identified by team members were used to select two initial safety priorities. The impact of CUSP on safety climate and teamwork was assessed through a pre-post comparison of results on the validated Safety Attitudes Questionnaire. Ninety-six percent of staff completed science of safety training as part of CUSP implementation, and 100% of staff completed the two-question safety assessment. The most frequently identified safety concerns were related to medications (n = 11, 28.2), diagnostic testing (n = 9, 25), and communication (n = 5, 14). The CUSP team initially prioritized communication and infection control, which led to standardization of work flows within the practice. Six months following CUSP implementation, large but nonstatistically significant increases were found for the percentage of survey respondents who reported knowledge of the proper channels for questions about patient safety, felt encouraged to report safety concerns, and believed that the work setting made it easy to learn from the errors of others. CUSP is a promising tool to improve safety climate and to identify and address safety concerns within ambulatory health care. Copyright © 2017 The Joint Commission. Published by Elsevier Inc.

  3. How Much Does Inbreeding Reduce Heterozygosity? Empirical Results from Aedes aegypti

    2017-01-01

    Deriving strains of mosquitoes with reduced genetic variation is useful, if not necessary, for many genetic studies. Inbreeding is the standard way of achieving this. Full-sib inbreeding the mosquito Aedes aegypti for seven generations reduced heterozygosity to 72% of the initial heterozygosity in contrast to the expected 13%. This deviation from expectations is likely due to high frequencies of deleterious recessive alleles that, given the number of markers studied (27,674 single nucleotide polymorphisms [SNPs]), must be quite densely spread in the genome.

    Full Text Available Cognitive ability tests are widely assumed to measure maximal intellectual performance and predictive associations between intelligence quotient (IQ scores and later mental health problems. Very few epidemiologic studies have been done to demonstrate the relationship between familial inbreeding and modest cognitive impairments in children.We aimed to estimate the effect of inbreeding on children's cognitive behavior in comparison with non-inbred children.A cohort of 408 children (6 to 15 years of age was selected from inbred and non-inbred families of five Muslim populations of Jammu region. The Wechsler Intelligence Scales for Children (WISC was used to measure the verbal IQ (VIQ, performance IQ (PIQ and full scale IQ (FSIQ. Family pedigrees were drawn to access the family history and children's inbred status in terms of coefficient of inbreeding (F.We found significant decline in child cognitive abilities due to inbreeding and high frequency of mental retardation among offspring from inbred families. The mean differences (95% C.I. were reported for the VIQ, being -22.00 (-24.82, -19.17, PIQ -26.92 (-29.96, -23.87 and FSIQ -24.47 (-27.35,-21.59 for inbred as compared to non-inbred children (p<0.001 [corrected].The higher risk of being mentally retarded was found to be more obvious among inbred categories corresponding to the degree of inbreeding and the same accounts least for non-inbred children (p<0.0001. We observed an increase in the difference in mean values for VIQ, PIQ and FSIQ with the increase of inbreeding coefficient and these were found to be statistically significant (p<0.05. The regression analysis showed a fitness decline (depression for VIQ (R2 = 0.436, PIQ (R2 = 0.468 and FSIQ (R2 = 0.464 with increasing inbreeding coefficients (p<0.01.Our comprehensive assessment provides the evidence for inbreeding depression on cognitive abilities among children.

  6. Conservation Biology and Traditional Ecological Knowledge: Integrating Academic Disciplines for Better Conservation Practice

    2006-12-01

    Full Text Available Conservation biology and environmental anthropology are disciplines that are both concerned with the identification and preservation of diversity, in one case biological and in the other cultural. Both conservation biology and the study of traditional ecoloigcal knowledge function at the nexus of the social and natural worlds, yet historically there have been major impediments to integrating the two. Here we identify linguistic, cultural, and epistemological barriers between the two disciplines. We argue that the two disciplines are uniquely positioned to inform each other and to provide critical insights and new perspectives on the way these sciences are practiced. We conclude by synthesizing common themes found in conservation success stories, and by making several suggestions on integration. These include cross-disciplinary publication, expanding memberships in professional societies and conducting multidisciplinary research based on similar interests in ecological process, taxonomy, or geography. Finally, we argue that extinction threats, be they biological or cultural/linguistic are imminent, and that by bringing these disciplines together we may be able to forge synergistic conservation programs capable of protecting the vivid splendor of life on Earth.

    Full Text Available Abstract Background Association studies consist in identifying the genetic variants which are related to a specific disease through the use of statistical multiple hypothesis testing or segregation analysis in pedigrees. This type of studies has been very successful in the case of Mendelian monogenic disorders while it has been less successful in identifying genetic variants related to complex diseases where the insurgence depends on the interactions between different genes and the environment. The current technology allows to genotype more than a million of markers and this number has been rapidly increasing in the last years with the imputation based on templates sets and whole genome sequencing. This type of data introduces a great amount of noise in the statistical analysis and usually requires a great number of samples. Current methods seldom take into account gene-gene and gene-environment interactions which are fundamental especially in complex diseases. In this paper we propose to use a non-parametric additive model to detect the genetic variants related to diseases which accounts for interactions of unknown order. Although this is not new to the current literature, we show that in an isolated population, where the most related subjects share also most of their genetic code, the use of additive models may be improved if the available genealogical tree is taken into account. Specifically, we form a sample of cases and controls with the highest inbreeding by means of the Hungarian method, and estimate the set of genes/environmental variables, associated with the disease, by means of Random Forest. Results We have evidence, from statistical theory, simulations and two applications, that we build a suitable procedure to eliminate stratification between cases and controls and that it also has enough precision in identifying genetic variants responsible for a disease. This procedure has been successfully used for the beta-thalassemia, which is

  8. Demographic mechanisms of inbreeding adjustment through extra-pair reproduction.

    Reid, Jane M; Duthie, A Bradley; Wolak, Matthew E; Arcese, Peter

    2015-07-01

    One hypothesis explaining extra-pair reproduction is that socially monogamous females mate with extra-pair males to adjust the coefficient of inbreeding (f) of extra-pair offspring (EPO) relative to that of within-pair offspring (WPO) they would produce with their socially paired male. Such adjustment of offspring f requires non-random extra-pair reproduction with respect to relatedness, which is in turn often assumed to require some mechanism of explicit pre-copulatory or post-copulatory kin discrimination. We propose three demographic processes that could potentially cause mean f to differ between individual females' EPO and WPO given random extra-pair reproduction with available males without necessarily requiring explicit kin discrimination. Specifically, such a difference could arise if social pairings formed non-randomly with respect to relatedness or persisted non-randomly with respect to relatedness, or if the distribution of relatedness between females and their sets of potential mates changed during the period through which social pairings persisted. We used comprehensive pedigree and pairing data from free-living song sparrows (Melospiza melodia) to quantify these three processes and hence investigate how individual females could adjust mean offspring f through instantaneously random extra-pair reproduction. Female song sparrows tended to form social pairings with unrelated or distantly related males slightly less frequently than expected given random pairing within the defined set of available males. Furthermore, social pairings between more closely related mates tended to be more likely to persist across years than social pairings between less closely related mates. However, these effects were small and the mean relatedness between females and their sets of potential extra-pair males did not change substantially across the years through which social pairings persisted. Our framework and analyses illustrate how demographic and social structuring within

    A global nursing leadership shortage is projected by the end of this decade. There is an urgent need to begin developing emerging nurse leaders now. This article describes the work of an academic-practice partnership collaborative of nurse leaders. The goal of the partnership is to develop and promote an innovative enhanced nursing administration master's program targeted to young emerging nurse leaders, who have not yet moved into formal leadership roles. An action research design is being used in program development and evaluation. Qualities needed by emerging leaders identified through research included a need to be politically astute, competency with business skills required of nurse leaders today, comfort with ambiguity, use of a caring approach, and leadership from a posture of innovation. The current curriculum was revised to include clinical immersion with a nurse leader from the first semester in the program, a change from all online to online/hybrid courses, innovative assignments, and a strong mentorship component. Eighteen young emerging nurse leaders began the program in January 2012. Early outcomes are positive. The emerging nurse leaders may be uniquely positioned, given the right skills sets, to be nurse leaders in the new age.

    Full Text Available Purpose. To examine financial and clinical work productivity outcomes associated with the use of the electronic health record (EHR. Methods. 191,360 billable clinical encounters were analyzed for 12 clinical providers over a 9-year study period during which an EHR was implemented. Main outcome measures were clinical revenues collected per provider and secondary outcomes were charge capture, patient visit coding levels, transcription costs, patient visit volume per provider, digital drawing, and digital imaging volume. Results. The difference in inflation adjusted net clinical revenue per provider per year did not change significantly in the period after EHR implementation (mean = $404,198; SD = $17,912 than before (mean = $411,420; SD = $39,366 (P=0.746. Charge capture, the proportion of higher- and lower-level visit codes for new and established patients, and patient visits per provider remained stable. A total savings of $188,951 in transcription costs occurred over a 4-year time period post-EHR implementation. The rate of drawing the ophthalmic exam in the EHR was low (mean = 2.28%; SD = 0.05% for all providers. Conclusions. This study did not show a clear financial gain after EHR implementation in an academic ophthalmology practice. Ophthalmologists do not rely on drawings to document the ophthalmic exam; instead, the ophthalmic exam becomes text-driven in a paperless world.

    The primary aim was to evaluate institutional anesthetic techniques utilized for postpartum tubal ligation (PPTL). Secondarily, academic institutions were surveyed on their clinical practice for PPTL. An institutional-specific retrospective review of patients with ICD-9 procedure codes for PPTL over a 2-year period was conducted. Obstetric anesthesia fellowship directors were surveyed on anesthetic management of PPTL. Labor and delivery unit. Internet survey. 202 PPTL procedures were reviewed. 47 institutions were surveyed; 26 responses were received. Timing of PPTL, anesthetic management, postoperative pain and length of stay. There was an epidural catheter reactivation failure rate of 26% (18/69 epidural catheter reactivation attempts). Time from epidural catheter insertion to PPTL was a significant factor associated with failure: median [IQR; range] time for successful versus failed epidural catheter reactivation was 17h [10-25; 3-55] and 28h [14-33; 5-42], respectively (P=0.028). Epidural catheter reactivation failure led to significantly longer times to provide surgical anesthesia than successful epidural catheter reactivation or primary spinal technique: median [IQR] 41min [33-54] versus 15min [12-21] and 19min [15-24], respectively (P8h and >24h post-delivery, respectively. Epidural catheter reactivation failure increases with longer intervals between catheter placement and PPTL. Failed epidural catheter reactivation increases anesthetic and operating room times. Our results and the significant variability in practice from our survey suggest recommendations on the timing and anesthetic management are needed to reduce unfulfilled PPTL procedures.

    The Hymenoptera have arrhenotokous haplodiploidy in which males normally develop from unfertilized eggs and are haploid, while females develop from fertilized eggs and are diploid. Multiple sex determination systems are known to underlie haplodiploidy, and the best understood is single-locus complementary sex determination (sl-CSD) in which sex is determined at a single polymorphic locus. Individuals heterozygous at the sex locus develop as females; individuals that are hemizygous (haploid) or homozygous (diploid) at the sex locus develop as males. sl-CSD can be detected with inbreeding experiments that produce diploid males in predictable proportions as well as sex ratio shifts due to diploid male production. This sex determination system is considered incompatible with inbreeding because the ensuing increase in homozygosity increases the production of diploid males that are inviable or infertile, imposing a high cost on matings between close relatives. However, in the solitary hunting wasp Euodynerus foraminatus, a species suspected of having sl-CSD, inbreeding may be common due to a high incidence of sibling matings at natal nests. In laboratory crosses with E. foraminatus, we find that sex ratios and diploid male production (detected as microsatellite heterozygosity) are consistent with sl-CSD, but not with other sex determination systems. This is the first documented example of sl-CSD in a hymenopteran with an apparent natural history of inbreeding, and thus presents a paradox for our understanding of hymenopteran genetics.

  15. Feral Pigeons (Columba livia Prefer Genetically Similar Mates despite Inbreeding Depression.

    Directory of Open Access Journals (Sweden)

    Gwenaël Jacob

    Full Text Available Avoidance of mating between related individuals is usually considered adaptive because it decreases the probability of inbreeding depression in offspring. However, mating between related partners can be adaptive if outbreeding depression is stronger than inbreeding depression or if females gain inclusive fitness benefits by mating with close kin. In the present study, we used microsatellite data to infer the parentage of juveniles born in a French colony of feral pigeons, which allowed us to deduce parent pairs. Despite detectable inbreeding depression, we found that pairwise relatedness between mates was significantly higher than between nonmates, with a mean coefficient of relatedness between mates of 0.065, approximately half the theoretical value for first cousins. This higher relatedness between mates cannot be explained by spatial genetic structure in this colonial bird; it therefore probably results from an active choice. As inbreeding but not outbreeding depression is observed in the study population, this finding accords with the idea that mating with genetically similar mates can confer a benefit in terms of inclusive fitness. Our results and published evidence suggest that preference for related individuals as mates might be relatively frequent in birds.

    We describe a large genealogy data base, which can be searched by computer, of 295,095 Amish and Mennonite individuals. The data base was constructed by merging our existing Anabaptist Genealogy Database 2.0 containing approximately 85,000 individuals with a genealogy file containing approximately 242,000 individuals, kindly provided by Mr. James Hostetler. The merging process corrected thousands of inconsistencies and eliminated hundreds of duplicate individuals. Geneticists have long been interested in Anabaptist populations because they are closed and have detailed written genealogies. The creation of an enlarged and unified data base affords the opportunity to examine inbreeding trends and correlates in these populations. We show the following results. The frequency of consanguineous marriages shows steady increase over time and reached approximately 85% for individuals born in 1940-1959. Among consanguineous marriages, the median kinship coefficient stayed stable in the 19th century, but rose from 0.0115 to 0.0151 in the 20th century. There are statistically significant associations (p < 0.0001) between inbreeding and family size and interbirth intervals in the 20th century. There is an association (p < 0.0005) between inbreeding and early death for individuals born in 1920-1959. However, this association reverses dramatically (p < 0.0005 in the opposite direction) for individuals born in 1960-1979. We tested for an association between inbreeding and being the mother of twins, but found none.

  17. Early-acting inbreeding depression and reproductive success in the highbush blueberry, Vaccinium corymbosum L.

    Krebs, S L; Hancock, J F

    1990-06-01

    Tetraploid Vaccinium corymbosum genotypes exhibit wide variability in seed set following self- and cross-pollinations. In this paper, a post-zygotic mechanism (seed abortion) under polygenic control is proposed as the basis for fertility differences in this species. A pollen chase experiment indicated that self-pollen tubes fertilize ovules, but are also 'outcompeted' by foreign male gametes in pollen mixtures. Matings among cultivars derived from a pedigree showed a linear decrease in seed number per fruit, and increase in seed abortion, with increasing relatedness among parents. Selfed (S1) progeny from self-fertile parents were largely self-sterile. At zygotic levels of inbreeding of F>0.3 there was little or no fertility, suggesting that an inbreeding threshold regulates reproductive success in V. corymbosum matings. Individuals below the threshold are facultative selfers, while those above it are obligate outcrossers. Inbreeding also caused a decrease in pollen viability, and reduced female fertility more rapidly than male fertility. These phenomena are discussed in terms of two models of genetic load: (1) mutational load - homozygosity for recessive embryolethal or sub-lethal mutations and (2) segregational load - loss of allelic interactions essential for embryonic vigor. Self-infertility in highbush blueberries is placed in the context of 'late-acting' self-incompatibility versus 'early-acting' inbreeding depression in angiosperms.

    Competency in evidence-based practice (EBP) is a requirement for graduate nurses. Despite a growing body of research exploring the EBP profiles of students, little research has explored the EBP profiles of nurse educators. To explore: the differences/similarities in the EBP profiles of US and UK clinical and academic faculty; the barriers nurse educators experience when teaching EBP; the impact of postgraduate education on EBP profile and; what nurse educators perceive "success" in implementing and teaching EBP to be. A cross-sectional online survey design was employed. Two Universities delivering undergraduate nursing education in the US and UK, in partnership with large hospital systems, small community hospitals, community settings, and independent sector health organisations. Eighty-one nurse educators working in academic and clinical contexts in the US and UK (US academic=12, US clinical=17, UK academic=9, UK clinical=43) were recruited opportunistically. Participants were emailed a weblink to an online survey, comprising demographic questions, the Evidence-Based Practice Questionnaire and open-ended questions about EBP barriers, facilitators and successes. Quantitative results indicated that academic faculty scored significantly higher on knowledge and skills of EBP, than clinical faculty, but revealed no other significant differences on EBP use or attitudes, or between US and UK professionals. Participants with postgraduate training scored significantly higher on EBP knowledge/skills, but not EBP attitudes or use. Qualitative findings identified key themes relating to EBP barriers and facilitators, including: Evidence-, organisational-, and teaching-related issues. Perceptions of successes in EBP were also described. Nurse educators working in the UK and US face similar EBP barriers to teaching and implementation, but view it positively and use it frequently. Clinical staff may require extra support to maintain their EBP knowledge and skills in

    Full Text Available In the 20th century, Tuvan music culture has undergone dramatic upheaval and a number of transformations. Today we face an acute need to rethink the achievements and losses incurred over that period of time. The objective of this article is to reconsider some basic parameters of Tuvan music culture that are responsible for preserving the integrity of its sound structure. The relevance of the topic is due to a current conceptual rift between the musical practices and their scholarly interpretations. In the Soviet period, culture throughout the entire USSR was solely driven by the European model of musical development with no reliance on practices typical for ethnical cultures. We are currently witnessing a decline in the numbers of those representing oral and audial traditional culture, while the numbers of music college graduates, those who studied at conservatoires, universities, academies of culture and arts, and thus come as bearers of values lying outside of the tradition. Tuvan musical practice is experiencing an invasion of academic vocabulary and non-relevant appraisal criteria. However, Tuvan musical culture, having always been primarily oral, has developed its own acoustic structure, as well as mechanisms and methods for non-scriptory transfer of knowledge. But these vernacular methods are still insufficiently explored. The author postulates that the system of Tuvan instrumental music organization is unique and acts as a basis for unconventional sound of musical instruments and xöömei (throat singing. Distinctive timbre and inimitable flair of the sound is achieved by original system of bourdon-overtone sound coordination. Music is created for audial enjoyment. But musicologists (mainly in Russia are still analyzing the notation they keep making of performed folk instrumental pieces and xöömei. Such an approach drastically narrows the entire panorama of traditional instrumental music. A positive factor is that contemporary Tuvan

    Full Text Available Much scholarly attention has been given to the English writing and publishing practices of the academics in non-Anglophone countries, but studies on such practices in the humanities and social sciences (HSS have in general been limited. The case of Mainland Chinese HSS academics is potentially interesting. On the one hand, international publications in these disciplines have been on the increase, which are also encouraged by the national research policy of “going-out”. On the other hand, unlike those in science and technology (S&T, such practices in the HSS are still much less institutionalized at the local level. In the study reported in this article, semi-structured interviews were conducted with nine academics in economics, sociology and archaeology from the Chinese Academy of Social Sciences (CASS, and all nine participants had prior experience in international publishing. With a focus on participants’ experiences and perceptions, findings from this study demonstrated the relatively passive role participants played in their international publications, the importance of various resources in bringing forth these publications, and the relations between participants’ alignments with the local or international community and their voluntary investment in participating in their practices. Implications of the study were also discussed.

    2013-10-01

    Although inbreeding is commonly known to depress individual fitness, the severity of inbreeding depression varies considerably across species. Among the factors contributing to this variation, family interactions, life stage and sex of offspring have been proposed, but their joint influence on inbreeding depression remains poorly understood. Here, we demonstrate that these three factors jointly shape inbreeding depression in the European earwig, Forficula auricularia. Using a series of cross-breeding, split-clutch and brood size manipulation experiments conducted over two generations, we first showed that sib mating (leading to inbred offspring) did not influence the reproductive success of earwig parents. Second, the presence of tending mothers and the strength of sibling competition (i.e. brood size) did not influence the expression of inbreeding depression in the inbred offspring. By contrast, our results revealed that inbreeding dramatically depressed the reproductive success of inbred adult male offspring, but only had little effect on the reproductive success of inbred adult female offspring. Overall, this study demonstrates limited effects of family interactions on inbreeding depression in this species and emphasizes the importance of disentangling effects of sib mating early and late during development to better understand the evolution of mating systems and population dynamics. © 2013 The Authors.

  7. Genome-wide estimates of coancestry and inbreeding in a closed herd of ancient Iberian pigs.

    Directory of Open Access Journals (Sweden)

    María Saura

    Full Text Available Maintaining genetic variation and controlling the increase in inbreeding are crucial requirements in animal conservation programs. The most widely accepted strategy for achieving these objectives is to maximize the effective population size by minimizing the global coancestry obtained from a particular pedigree. However, for most natural or captive populations genealogical information is absent. In this situation, microsatellites have been traditionally the markers of choice to characterize genetic variation, and several estimators of genealogical coefficients have been developed using marker data, with unsatisfactory results. The development of high-throughput genotyping techniques states the necessity of reviewing the paradigm that genealogical coancestry is the best parameter for measuring genetic diversity. In this study, the Illumina PorcineSNP60 BeadChip was used to obtain genome-wide estimates of rates of coancestry and inbreeding and effective population size for an ancient strain of Iberian pigs that is now in serious danger of extinction and for which very accurate genealogical information is available (the Guadyerbas strain. Genome-wide estimates were compared with those obtained from microsatellite and from pedigree data. Estimates of coancestry and inbreeding computed from the SNP chip were strongly correlated with genealogical estimates and these correlations were substantially higher than those between microsatellite and genealogical coefficients. Also, molecular coancestry computed from SNP information was a better predictor of genealogical coancestry than coancestry computed from microsatellites. Rates of change in coancestry and inbreeding and effective population size estimated from molecular data were very similar to those estimated from genealogical data. However, estimates of effective population size obtained from changes in coancestry or inbreeding differed. Our results indicate that genome-wide information represents a

    The present paper examines consanguineous marriages occurring between 1874 and 1975 in three valleys (Tormes, Alberche, and Tiétar) in the Sierra de Gredos mountain range, Avila province, Spain. Information was obtained from parish registers of 42 localities, corresponding to a total of 41,696 weddings. Consanguineous marriages were defined as those up to the third degree of consanguinity (second cousins). From 1874 to 1975 the percentage of related mates was 4.45% and the inbreeding coefficient was 0.0011868 (for 1874 to 1917 corresponding figures up to the fourth degree were 16.44% and 0.00 19085, respectively). In order to ascertain the characteristics and evolution of mating patterns in Gredos, the contribution of each degree of kinship was analyzed as a whole and then for each valley separately. Regarding total consanguineous marriages in Gredos, there is a low frequency of uncle-niece matings (0.21%) and a first-second cousin mating ratio (C22/C33) of 0.23 (up to the third degree of consanguinity). Before 1918 multiple matings (i.e., those involving more than a single relationship) accounted for 19.16% of consanguineous marriages (up to the fourth degree). The observed frequencies of multiple consanguineous marriages was, on average, about twice that expected at random, and the proportion of such marriages to total inbreeding was 34.65%. The temporal change of the Gredos inbreeding pattern was characterized by a recent decrease; the highest inbreeding levels correspond to the period from 1915 to 1944. Finally, intervalley differences (maximum inbreeding coefficient in the Tormes, minimum in the Tiétar) are interpreted considering the geography, population size, and population mobility for each valley

  9. Inbreeding avoidance influences the viability of reintroduced populations of African wild dogs (Lycaon pictus.

    Full Text Available The conservation of many fragmented and small populations of endangered African wild dogs (Lycaon pictus relies on understanding the natural processes affecting genetic diversity, demographics, and future viability. We used extensive behavioural, life-history, and genetic data from reintroduced African wild dogs in South Africa to (1 test for inbreeding avoidance via mate selection and (2 model the potential consequences of avoidance on population persistence. Results suggested that wild dogs avoided mating with kin. Inbreeding was rare in natal packs, after reproductive vacancies, and between sibling cohorts (observed on 0.8%, 12.5%, and 3.8% of occasions, respectively. Only one of the six (16.7% breeding pairs confirmed as third-order (or closer kin consisted of animals that were familiar with each other, while no other paired individuals had any prior association. Computer-simulated populations allowed to experience inbreeding had only a 1.6% probability of extinction within 100 years, whereas all populations avoiding incestuous matings became extinct due to the absence of unrelated mates. Populations that avoided mating with first-order relatives became extinct after 63 years compared with persistence of 37 and 19 years for those also prevented from second-order and third-order matings, respectively. Although stronger inbreeding avoidance maintains significantly more genetic variation, our results demonstrate the potentially severe demographic impacts of reduced numbers of suitable mates on the future viability of small, isolated wild dog populations. The rapid rate of population decline suggests that extinction may occur before inbreeding depression is observed.

    Purpose: To determine what factors US radiation oncology residents consider when choosing academic or nonacademic careers. Methods and Materials: A 20-question online survey was developed and sent to all US radiation oncology residents to assess factors that influence their career interest. Residents were asked to rate their interest in academics (A) versus private practice (PP) on a 0 (strong interest in A) to 100 (strong interest in PP) scale. Responses were classified as A (0-30), undecided (40-60), and PP (70-100). Residents were also asked to rank 10 factors that most strongly influenced their career interest. Results: Three hundred thirty-one responses were collected, of which 264 were complete and form the basis for this analysis. Factors that correlated with interest in A included having a PhD (P=.018), postgraduate year level (P=.0006), research elective time (P=.0003), obtaining grant funding during residency (P=.012), and number of publications before residency (P=.0001), but not number of abstracts accepted in the past year (P=.65) or publications during residency (P=.67). The 3 most influential factors for residents interested in A were: (1) baseline interest before residency; (2) academic role models; and (3) research opportunities during residency. The 3 most influential factors for residents interested in PP were: (1) baseline interest before residency; (2) academic role models; and (3) academic pressure and obligations. Conclusions: Interest in A correlated with postgraduate year level, degree, and research time during residency. Publications before but not during residency correlated with academic interest, and baseline interest was the most influential factor. These data can be used by residency program directors to better understand what influences residents' career interest

  14. The association of genotype-based inbreeding coefficient with a range of physical and psychological human traits.

    Karin J H Verweij

    Full Text Available Across animal species, offspring of closely related mates exhibit lower fitness, a phenomenon called inbreeding depression. Inbreeding depression in humans is less well understood because mating between close relatives is generally rare and stigmatised, confounding investigation of its effect on fitness-relevant traits. Recently, the availability of high-density genotype data has enabled quantification of variation in distant inbreeding in 'outbred' human populations, but the low variance of inbreeding detected from genetic data in most outbred populations means large samples are required to test effects, and only a few traits have yet been studied. However, it is likely that isolated populations, or those with a small effective population size, have higher variation in inbreeding and therefore require smaller sample sizes to detect inbreeding effects. With a small effective population size and low immigration, Northern Finland is such a population. We make use of a sample of ∼5,500 'unrelated' individuals in the Northern Finnish Birth Cohort 1966 with known genotypes and measured phenotypes across a range of fitness-relevant physical and psychological traits, including birth length and adult height, body mass index (BMI, waist-to-hip ratio, blood pressure, heart rate, grip strength, educational attainment, income, marital status, handedness, health, and schizotypal features. We find significant associations in the predicted direction between individuals' inbreeding coefficient (measured by proportion of the genome in runs of homozygosity and eight of the 18 traits investigated, significantly more than the one or two expected by chance. These results are consistent with inbreeding depression effects on a range of human traits, but further research is needed to replicate and test alternative explanations for these effects.

    The magnitude and variation of inbreeding depression (ID) within populations is important for the evolution and maintenance of mixed mating systems.

    Twelve crosses of aromatic rice utilizing four γ-ray induced mutants 88-8-3 and 33-9-15 of Tulaipanja and 124-17-4 and 21-6-1 of Gobindabhog and three basmati varieties were evaluated for heterosis and inbreeding depression for different panicle characters. All the hybrids except the two hybrids of 124-17-4 with Pakistan Basmati and Pusa Basmati I manifested significantly positive heterosis for grain yield panicle -1 . High magnitude of heterosis coupled with positive inbreeding depression for panicle length, secondary branches panicle -1 , spikelet number panicle -1 , panicle weight and grain yield panicle -1 in several crosses indicating the presence of nonadditive gene action. The results indicate the scope of exploiting heterosis in aromatic rice. (author)

    The isonymic method has been amply used to assess the approximate genetic structure of human communities. The objective of the study was to evaluate the magnitude of genetic isolation and inbreeding customs in 57 communities from three rural municipalities of Honduras using isonymy techniques. The list of 408 different surnames from 20712 voters registered in the national electoral organism, residing in the 57 Honduran communities, was used for this study. For each community, random (IR), non-random (IN), and total (IT) isonymy values were calculated in order to assess inbreeding coefficients FST, FIS and FIT. High consanguinity due to isolation and to endogamous customs was unveiled in many communities. Significant deviation from the exogamous behavior typical of many human populations was observed in the three studied municipalities, when compared to other Honduran populations. The studied communities present high consanguinity due to isolation, ethnic segregation and/or endogamous customs.

    This is the first research into preparation for multicultural clinical psychology practice in Europe. It applies the theory of multicultural counselling competency (MCC) to a case study in the Netherlands. It was hypothesized that cross-cultural practice experience, identification as a cultural minority, and satisfaction with cultural training was associated with MCC. The Multicultural Awareness Knowledge and Skills Survey was completed by 106 participants (22 students, 10 academics, 74 alumni) from clinical psychology masters’ programs. MANOVA detected a main effect of cross-cultural experience on MCC for all groups and universities. The data were enriched with exploratory qualitative data from 14 interviews (5 students, 5 academics, 4 alumni). Interpretative Phenomenological Analysis revealed three themes: limitations of clinical psychology, strategies for culturally competent practice, and strategies for cultural competency development. These outcomes suggest that cultural competency continues to require attention in master’s programs. The paper makes recommendations for further research enquiry related to training clinical psychologists to practice in Europe’s multicultural societies. PMID:29899800

  19. Heterosis at Allozyme Loci under Inbreeding and Crossbreeding in PINUS ATTENUATA

    1986-01-01

    The dependence of heterosis at isozyme loci on inbreeding and crossbreeding was studied in 10-yr-old trees of knobcone pine (Pinus attenuata Lemm.). Heterozygosity was determined at 24 polymorphic isozyme loci and related to the rate of vegetative growth and cone production. The inbreds, created by selfpollination, had 46% of the heterozygosity of their mothers; the crossbreds, created by interpopulation crossing, had 155% of the heterozygosity of their mothers. Within the crossbreds, hetero...

    The number and size of tiger populations continue to decline owing to habitat loss, habitat fragmentation and poaching of tigers and their prey. As a result, tiger populations have become small and highly structured. Current populations have been isolated since the early 1970s or for approximately seven generations. The objective of this study is to explore how inbreeding may be affecting the persistence of remaining tiger populations and how dispersal, either natural or artificial, may reduce the potentially detrimental effect of inbreeding depression. We developed a tiger simulation model and used published levels of genetic load in mammals to simulate inbreeding depression. Following a 50 year period of population isolation, we introduced one to four dispersing male tigers per generation to explore how gene flow from nearby populations may reduce the negative impact of inbreeding depression. For the smallest populations, even four dispersing male tigers per generation did not increase population viability, and the likelihood of extinction is more than 90% within 30 years. Unless habitat connectivity is restored or animals are artificially introduced in the next 70 years, medium size wild populations are also likely to go extinct, with only four to five of the largest wild tiger populations likely to remain extant in this same period without intervention. To reduce the risk of local extinction, habitat connectivity must be pursued concurrently with efforts to increase population size (e.g. enhance habitat quality, increase habitat availability). It is critical that infrastructure development, dam construction and other similar projects are planned appropriately so that they do not erode the extent or quality of habitat for these populations so that they can truly serve as future source populations. © 2014 The Author(s) Published by the Royal Society.

    The coffee berry borer beetle #Hypothenemus hampei$ (Ferrari) (#Curculionidae$ : #Scolytinae$) is the major insect pest of coffee and has spread to most of the coffee-growing countries of the world. This beetle also displays an usual life cycle, with regular sibling mating. This regular inbreeding and the population bottlenecks occuring on colonization of new regions should lead to low levels of genetic diversity. We were therefore interested in determining the level of nucleotide variation i...

  2. Inbreeding coefficients and degree of consanguineous marriages in Spain: a review.

    Fuster, Vicente; Colantonio, Sonia Edith

    2003-01-01

    The contribution of consanguineous marriages corresponding to uncle-niece or aunt-nephew (C12), first cousin (C22), first cousin once removed (C23), and second cousin (C33) to the inbreeding coefficient (alpha) was analyzed from a sample of Spanish areas and periods. Multiple regressions were performed taking as independent variables the different degrees of consanguinity previously selected (C12, C22, C23, and C33) and as dependent variable the inbreeding coefficient (alpha). According to the results obtained for any degree and period, rural frequencies always surpass urban. However, the pattern is similar in both areas. In the period where consanguinity was more elevated (1890-1929) the C22/C33 ratio increased. Its variation is not due to C22 and C33 changes in the same way. In rural areas, this ratio surpasses the expected value by a factor of 2-3, but in urban areas it was 7-10 times larger, in some cases due to migration. While in rural Spain the C33 frequency was approximately 1.5 times C22, in cities C22 was 1.5 times C33. The best fit among the various types of consanguineous matings and alpha involves a lineal relationship. Regardless of the number of variables contributing significantly to alpha, C22 matings are always present. Moreover, their standardized (beta) coefficients are the highest. The above indicates that this consanguineous relationship conditions the inbreeding coefficient the most. In the period of greater consanguinity, close relationships, uncle-niece C12, and first cousin once removed (C23) make a significant contribution to alpha. In rural Spain second cousins (C33) always significantly determined alpha; however, in cities the inbreeding variation was mainly due to C12 and C23. Copyright 2003 Wiley-Liss, Inc.

    Full Text Available The accumulation of inbreeding and the loss of genetic diversity is a potential problem in the modern swine breeds in China. Therefore, the purpose of this study was to analyze the pedigrees of Chinese Duroc (CD, Landrace (CL and Yorkshire (CY swine to estimate the past and current rates of inbreeding, and to identify the main causes of genetic diversity loss. Pedigree files from CD, CL and CY containing, 4529, 16,776 and 22,600 records, respectively, were analyzed. Pedigree completeness indexes of the three breeds, accounting for one generation back, were 83.72, 93.93 and 93.59%, respectively. The estimated average annual inbreeding rates for CD, CL and CY in recent three years were 0.21, 0.19 and 0.13%, respectively. The estimated average percentage of genetic diversity loss within each breed in recent three years was about 8.92, 2.19, and 3.36%, respectively. The average relative proportion of genetic diversity loss due to unequal contributions of founders in CD, CL and CY was 69.09, 57.95 and 60.57%, and due to random genetic drift was 30.91, 42.05 and 39.43%, respectively. The estimated current effective population size for CD, CL and CY was 76, 117 and 202, respectively. Therefore, CD has been found to have lost considerable genetic diversity, demanding priority for optimizing the selection and mating to control future coancestry and inbreeding. Unequal contribution of founders was a major cause of genetic diversity loss in Chinese swine breeds and random genetic drift also showed substantial impact on the loss of diversity.

    1. The genetic constitution of populations may significantly affect demography. Founder populations or isolated remnants may show inbreeding depression, while established populations can be strongly adapted to the local environment. Gene exchange between populations can lead to better performance if heterozygosity levels are restored (heterosis), or to reduced performance if coadapted gene complexes are disrupted (outbreeding depression). 2. Five populations of the self-incompatible perennial Arnica montana (Asteraceae) were analysed for the demographic consequences of inbreeding and of intra- and interpopulation outcrossing, using both small and large populations as donors for the latter. We analysed seed production and seed weight and monitored growth, survival and flowering of offspring introduced as seeds and as 4-week-old seedlings in a 4-year field experiment. 3. Reduced seed set after selfing was probably due to the self-incompatibility system rather than to inbreeding depression. There was a significant increase for seed set after interpopulation crosses, which resulted from the alleviation of low mate availability in one of the small populations. 4. Significant inbreeding depression was observed for growth rates of plants introduced as seedlings. We found significant heterosis for flowering probability of plants introduced as seeds, but for plants introduced as seedlings, heterosis for seedling size and flowering probability was only marginally significant. Outbreeding depression was not observed. 5. The results of this study are important for reinforcement measures in small, remnant populations. Significant differences among populations for all measured fitness components suggest that reinforcement is best achieved using material from several populations. 6. The observed higher survival of seedlings as compared with seeds suggests that it is better to plant individuals than to sow. Sowing, however, is easier and cheaper, and was more likely to eliminate

  6. Understanding the psychology of seeking support to increase Health Science student engagement in academic support services. A Practice Report

    Full Text Available Increasing student engagement within higher education academic support services is a constant challenge. Whilst engagement with support is positively associated with successful retention, and non-engagement connected to attrition, the most vulnerable students are often the least likely to engage. Our data has shown that Health Science students are reluctant to engage with academic support services despite being made aware of their academic deficiencies. The “psychology of seeking support” was used as a lens to identify some of the multifaceted issues around student engagement. The School of Health Sciences made attendance at support courses compulsory for those students who were below the benchmark score in a post entrance literacy test. Since the policy change was implemented, there has been a 50% reduction in the fail rate of “at risk” students in a core literacy unit. These findings are encouraging and will help reduce student attrition in the long term.

  7. So, You Think You Have an Idea: A Practical Risk Reduction-Conceptual Model for Academic Translational Research

    Directory of Open Access Journals (Sweden)

    2017-04-01

    Full Text Available Translational research for new drugs, medical devices, and diagnostics encompasses aspects of both basic science and clinical research, requiring multidisciplinary skills and resources that are not all readily available in either a basic laboratory or clinical setting alone. We propose that, to be successful, “translational” research ought to be understood as a defined process from basic science through manufacturing, regulatory, clinical testing all the way to market. The authors outline a process which has worked well for them to identify and commercialize academic innovation. The academic environment places a high value on novelty and less value on whether, among other things, data are reproducible, scalable, reimbursable, or have commercial freedom to operate. In other words, when investors, strategic companies, or other later stage stakeholders evaluate academic efforts at translational research the relative lack of attention to clinical, regulatory, reimbursement, and manufacturing and intellectual property freedom to operate almost universally results in more questions and doubts about the potential of the proposed product, thereby inhibiting further interest. This contrasts with industry-based R&D, which often emphasizes manufacturing, regulatory and commercial factors. Academics do not so much choose to ignore those necessary and standard elements of translation development, but rather, they are not built into the culture or incentive structure of the university environment. Acknowledging and addressing this mismatch of approach and lack of common language in a systematic way facilitates a more effective “translation” handoffs of academic project concepts into meaningful clinical solutions help translational researchers more efficiently develop and progress new and better medical products which address validated needs. The authors provide an overview and framework for academic researchers to use which will help them define the

    The coffee berry borer beetle Hypothenemus hampei (Ferrari) (Curculionidae: Scolytinae) is the major insect pest of coffee and has spread to most of the coffee-growing countries of the world. This beetle also displays an unusual life cycle, with regular sibling mating. This regular inbreeding and the population bottlenecks occurring on colonization of new regions should lead to low levels of genetic diversity. We were therefore interested in determining the level of nucleotide variation in nuclear and mitochondrial genomes of this beetle worldwide. Here we show that two nuclear loci (Resistance to dieldrin and ITS2) are completely invariant, whereas some variability is maintained at a mitochondrial locus (COI), probably corresponding to a higher mutation rate in the mitochondrial genome. Phylogenetic analysis of the mitochondrial data shows only two clades of beetle haplotypes outside of Kenya, the proposed origin of the species. These data confirm that inbreeding greatly reduces nucleotide variation and suggest the recent global spread of only two inbreeding lines of this bark beetle.

  9. Inbreeding affects sexual signalling in males but not females of Tenebrio molitor.

    In many species of animals, individuals advertise their quality with sexual signals to obtain mates. Chemical signals such as volatile pheromones are species specific, and their primary purpose is to influence mate choice by carrying information about the phenotypic and genetic quality of the sender. The deleterious effects of consanguineous mating on individual quality are generally known, whereas the effect of inbreeding on sexual signalling is poorly understood. Here, we tested whether inbreeding reduces the attractiveness of sexual signalling in the mealworm beetle, Tenebrio molitor, by testing the preferences for odours of inbred and outbred (control) individuals of the opposite sex. Females were more attracted to the odours produced by outbred males than the odours produced by inbred males, suggesting that inbreeding reduces the attractiveness of male sexual signalling. However, we did not find any difference between the attractiveness of inbred and outbred female odours, which may indicate that the quality of females is either irrelevant for T. molitor males or quality is not revealed through female odours.

  10. The Relationship between Runs of Homozygosity and Inbreeding in Jersey Cattle under Selection.

    Directory of Open Access Journals (Sweden)

    Eui-Soo Kim

    Full Text Available Inbreeding is often an inevitable outcome of strong directional artificial selection but on average it reduces population fitness with increased frequency of recessive deleterious alleles. Runs of homozygosity (ROH representing genomic autozygosity that occur from mating between selected and genomically related individuals may be able to reveal the regions affecting fitness. To examine the influence of genomic autozygosity on fitness, we used a genome-wide association test to evaluate potential negative correlations between ROH and daughter pregnancy rate (DPR or somatic cell score (SCS in US Jersey cattle. In addition, relationships between changes of local ROH and inbreeding coefficients (F were assessed to locate genomic regions with increased inbreeding. Despite finding some decreases in fertility associated with incremental increases in F, most emerging local ROH were not significantly associated with DPR or SCS. Furthermore, the analyses of ROH could be approximated with the most frequent haplotype(s, including the associations of ROH and F or traits. The analysis of the most frequent haplotype revealed that associations of ROH and fertility could be accounted for by the additive genetic effect on the trait. Thus, we suggest that a change of autozygosity is more likely to demonstrate footprints of selected haplotypes for production rather than highlight the possible increased local autozygosity of a recessive detrimental allele resulting from the mating between closely related animals in Jersey cattle.

  11. Mutual mate choice: when it pays both sexes to avoid inbreeding.

    Directory of Open Access Journals (Sweden)

    Mathieu Lihoreau

    Full Text Available Theoretical models of sexual selection predict that both males and females of many species should benefit by selecting their mating partners. However, empirical evidence testing and validating this prediction is scarce. In particular, whereas inbreeding avoidance is expected to induce sexual conflicts, in some cases both partners could benefit by acting in concert and exerting mutual mate choice for non-assortative pairings. We tested this prediction with the gregarious cockroach Blattella germanica (L.. We demonstrated that males and females base their mate choice on different criteria and that choice occurs at different steps during the mating sequence. Males assess their relatedness to females through antennal contacts before deciding to court preferentially non-siblings. Conversely, females biased their choice towards the most vigorously courting males that happened to be non-siblings. This study is the first to demonstrate mutual mate choice leading to close inbreeding avoidance. The fact that outbred pairs were more fertile than inbred pairs strongly supports the adaptive value of this mating system, which includes no "best phenotype" as the quality of two mating partners is primarily linked to their relatedness. We discuss the implications of our results in the light of inbreeding conflict models.

    The Thoroughbred horse has played an important role in both sporting and economic aspects of society since the establishment of the breed in the 1700s. The extensive pedigree and phenotypic information available for the Thoroughbred horse population provides a unique opportunity to examine the effects of 300 years of selective breeding on genetic load. By analysing the relationship between inbreeding and racing performance of 135,572 individuals, we found that selective breeding has not efficiently alleviated the Australian Thoroughbred population of its genetic load. However, we found evidence for purging in the population that might have improved racing performance over time. Over 80% of inbreeding in the contemporary population is accounted for by a small number of ancestors from the foundation of the breed. Inbreeding to these ancestors has variable effects on fitness, demonstrating that an understanding of the distribution of genetic load is important in improving the phenotypic value of a population in the future. Our findings hold value not only for Thoroughbred and other domestic breeds, but also for small and endangered populations where such comprehensive information is not available.

    To investigate the possible effects of the Food and Drug Administration (FDA) Public Health Notifications in 2008 and 2011 regarding surgical trends in transvaginal mesh (TVM) placement for stress urinary incontinence (SUI) and related mesh revision surgery in Female Pelvic Medicine & Reconstructive Surgery (FPMRS) practice in tertiary care academic medical centers in the United States. Surgical volume for procedures performed primarily by FPMRS surgeons at eight academic institutions across the US was collected using Current Procedural Terminology (CPT) codes for stress urinary incontinence repair and revision surgeries from 2007 to 2013. SAS statistical software was used to assess for trends in the data. There was a decrease in the use of synthetic mesh sling for the treatment of SUI at academic tertiary care centers over the past 7 years; however, this was not statistically significant. While the total number of surgical interventions for SUI remained stable, there was an increase in the utilization of autologous fascia pubovaginal slings (AFPVS). The number of mesh sling revision surgeries, including urethrolysis and removal or revision of slings, increased almost three-fold at these centers. These observed trends suggest a possible effect of the FDA Public Health Notifications regarding TVM on surgical practice for SUI in academic centers, even though they did not specifically warn against the use of synthetic mesh for this indication. Indications for surgery, complications, and outcomes were not evaluated during this retrospective study. However, such data may provide alternative insights into reasons for the observed trends.

    2009-01-01

    Full Text Available This paper investigated the relations between social competence, parental practices and academic performance in adolescents. 66 adolescents took part in the study and they were divided in two groups: high and low academic performance. The tools used in this research were CBCL and YSR (Achenbach, 1991, and IEP (Gomide, 2006. The results showed that adolescents of high academic achievements are perceived by the parents as socially competent and are raised with more positive parental practices. The data indicated that academic performance is also influenced by the social competence and the way the adolescents are educated by the parents. Those aspects should be considered in interventions that aim at promoting the improvement of academic performance and development of a behavior adjusted to the school.

    In France, community pharmacy students performed a hospital pharmacy practice experience during the 5th year of the university curriculum. The purpose of a part of the content of the academic teaching program delivered before this practice experience is to prepare the students for their future hospital activities. It should enable them for the practical use of knowledge in order to improve pharmacotherapy, laboratory diagnosis and monitoring of patients' care. The aim of this study was to show if there are gaps in this program. Fourteen students performing their clerkship in a teaching hospital were invited to highlight these gaps when they were gradually immersed in the pharmaceutical care. They did so under the careful observation of hospital pharmacist preceptors. These practitioners referred to professional guidelines, documentary tools used in daily clinical practice and publications supporting their pharmaceutical care practices. Shortcomings and gaps identified were: how to communicate with other healthcare professionals and the content of verbal exchanges, how to conduct a patient-centered consultation, documentation tools required for relevant pharmacist' interventions, codification of pharmacist's interventions, risks related to drug packaging and benefit risk assessment of health information technologies. These gaps represent a handicap by delaying the process that led to move from student to healthcare professional. Hospital pharmacist preceptors have to fill in these gaps before engaging students in pharmaceutical care. These results invite to revise partly the content of the academic teaching program delivered before the 5th year hospital pharmacy practice experience.

    2000-01-01

    A questionnaire was mailed to 148 publicly and privately supported academic health sciences libraries affiliated with Association of American Medical Colleges (AAMC-accredited medical schools in the United States and Canada to determine level of access and services provided to the general public. For purposes of this study, "general public" was defined as nonaffiliated students or health care professionals, attorneys and other nonhealth-related professionals, patients from affiliated or other hospitals or clinics, and general consumers. One hundred five (71%) libraries responded. Results showed 98% of publicly supported libraries and 88% of privately supported libraries provided access to some or all of the general public. Publicly supported libraries saw greater numbers of public patrons, often provided more services, and were more likely to circulate materials from their collections than were privately supported libraries. A significant number of academic health sciences libraries housed a collection of consumer-oriented materials and many provided some level of document delivery service, usually for a fee. Most allowed the public to use some or all library computers. Results of this study indicated that academic health sciences libraries played a significant role in serving the information-seeking public and suggested a need to develop written policies or guidelines covering the services that will be provided to minimize the impact of this service on primary clientele.

    The epidemiology of football-related concussions has been extensively examined. However, although football players experience more at-risk exposure time during practices than competitions, there is a dearth of literature examining the nature of the activities or equipment worn during practice. In particular, varying levels of equipment worn during practices may place players at varying levels of risk for concussion. To describe the epidemiology of NCAA men's football concussions that occurred during practices from the 2004-2005 to 2008-2009 academic years by amount of equipment worn. Descriptive epidemiology study. Men's collegiate football data from the National Collegiate Athletic Association Injury Surveillance System (NCAA ISS) during the 5-year study period were analyzed. Injury rates and injury rate ratios (RRs) were reported with 95% confidence intervals. During the study period, 795 concussions were reported during practices, resulting in an injury rate of 0.39 per 1000 athlete-exposures (AEs) (95% CI, 0.36-0.42). Among NCAA divisions, Division III had the highest concussion rate (0.54/1000 AEs), followed by Division I (0.34/1000 AEs) and Division II (0.24/1000 AEs) (all P values for RRs comparing divisionsconcussions in practice occurred when players were fully padded (69.9%), followed by wearing shells (23.5%) and helmets only (1.9%). The practice concussion rate was higher in fully padded practices (0.66/1000 AEs) compared with practices when shells were worn (0.33/1000 AEs; RR=1.99 [95% CI, 1.69-2.35]; Pconcussion rate of the preseason (0.76/1000 AEs) was higher than that of the regular season (0.18/1000 AEs; RR=4.14 [95% CI, 3.55-4.83]; Pconcussion rate were scrimmages (1.55/1000 AEs). Although only 3 concussions were sustained during scrimmage practices in which players wore shells, the concussion rate (2.84/1000 AEs) was higher than all other reported rates. Practice concussion rates are highest during fully padded practices, preseason practices, and

    Full Text Available Milk yield records (305d, 2X, actual milk yield of 123,639 registered first lactation Holstein cows were used to compare linear regression (y = β0 + β1X + e ,quadratic regression, (y = β0 + β1X + β2X2 + e cubic regression (y = β0 + β1X + β2X2 + β3X3 + e and fixed factor models, with cubic-spline interpolation models, for estimating the effects of inbreeding on milk yield. Ten animal models, all with herd-year-season of calving as fixed effect, were compared using the Akaike corrected-Information Criterion (AICc. The cubic-spline interpolation model with seven knots had the lowest AICc, whereas for all those labeled as "traditional", AICc was higher than the best model. Results from fitting inbreeding using a cubic-spline with seven knots were compared to results from fitting inbreeding as a linear covariate or as a fixed factor with seven levels. Estimates of inbreeding effects were not significantly different between the cubic-spline model and the fixed factor model, but were significantly different from the linear regression model. Milk yield decreased significantly at inbreeding levels greater than 9%. Variance component estimates were similar for the three models. Ranking of the top 100 sires with daughter records remained unaffected by the model used.

    Academic service learning (ASL) is an active teaching-learning approach to engage students in meaningful hands-on activities to serve community-based needs. Nine health professions students from a private college and a private university in the northeastern United States volunteered to participate in an ASL trip to Morocco. The participants were interviewed to reflect on their experiences. This article discusses the lessons learned from students' ASL experiences regarding integrating ASL into educational programs. The authors recommend a paradigm shift in nursing and dental hygiene curricula to appreciate diversity and promote cultural competency, multidisciplinary teamwork, and ethics-based education.

  12. The use (or misuse) of microsatellite allelic distances in the context of inbreeding and conservation genetics.

    Science.gov (United States)

    Hansson, Bengt

    2010-03-01

    In line with inbreeding theory, genetic diversity at a set of molecular markers may explain variation in fitness-associated traits in partially inbred populations, and such associations will appear as 'genotype-fitness correlations'. An individual genetic diversity index specifically used for microsatellites is 'mean d(2)', i.e. the mean squared distance between alleles. The original hypothesis for mean d(2)-fitness correlations assumes that mean d(2) captures fitness effects at both ends of the inbreeding-outbreeding spectrum. This hypothesis received strong criticism from work showing that even a plain diversity estimate such as multi-locus heterozygosity (MLH) outperforms mean d(2) as a predictor of the inbreeding coefficient and fitness in most realistic situations. Despite this critique, the mean d(2)-approach is still used frequently in ecological and evolutionary research, producing results suggesting that mean d(2) sometimes provides a stronger prediction of fitness than does MLH. In light of the critique, such results are unexpected, but potential explanations for them may exist (at least hypothetically), including scenarios based on close linkage and recent admixture. Nevertheless, a major caveat is that it is very difficult to predict a priori if mean d(2) will improve the genotype-fitness correlation, which in turn makes objective interpretations difficult. Mean d(2)-fitness associations are potentially interesting, but the fact that we cannot easily understand them is problematic and should be thoroughly addressed in each study. Therefore, instead of hastily reached interpretations of mean d(2)-fitness correlations, conclusions need support from complementary analyses, e.g. verifying admixture of genetically structured populations.

  14. Pedigrees or markers: Which are better in estimating relatedness and inbreeding coefficient?

    Science.gov (United States)

    Wang, Jinliang

    2016-02-01

    Individual inbreeding coefficient (F) and pairwise relatedness (r) are fundamental parameters in population genetics and have important applications in diverse fields such as human medicine, forensics, plant and animal breeding, conservation and evolutionary biology. Traditionally, both parameters are calculated from pedigrees, but are now increasingly estimated from genetic marker data. Conceptually, a pedigree gives the expected F and r values, FP and rP, with the expectations being taken (hypothetically) over an infinite number of individuals with the same pedigree. In contrast, markers give the realised (actual) F and r values at the particular marker loci of the particular individuals, FM and rM. Both pedigree (FP, rP) and marker (FM, rM) estimates can be used as inferences of genomic inbreeding coefficients FG and genomic relatedness rG, which are the underlying quantities relevant to most applications (such as estimating inbreeding depression and heritability) of F and r. In the pre-genomic era, it was widely accepted that pedigrees are much better than markers in delineating FG and rG, and markers should better be used to validate, amend and construct pedigrees rather than to replace them. Is this still true in the genomic era when genome-wide dense SNPs are available? In this simulation study, I showed that genomic markers can yield much better estimates of FG and rG than pedigrees when they are numerous (say, 10(4) SNPs) under realistic situations (e.g. genome and population sizes). Pedigree estimates are especially poor for species with a small genome, where FG and rG are determined to a large extent by Mendelian segregations and may thus deviate substantially from their expectations (FP and rP). Simulations also confirmed that FM, when estimated from many SNPs, can be much more powerful than FP for detecting inbreeding depression in viability. However, I argue that pedigrees cannot be replaced completely by genomic SNPs, because the former allows for

    Full Text Available The complex analysis of the pedigree records of Czech Landrace (CLA, Czech Large White-dam line (CLWd, Czech Large White-sire line (CLWs, Duroc (DC, and Pietrain (PN was performed to determine trends of genetic diversity (GD, and to find the main sources of the GD loss. The total size of the pedigree was 132,365, 391,151, 32,913, 13,299, and 7,160 animals in CLA, CLWd, CLWs, DC, and PN, respectively. Animals born in the years 2011 through 2013 were assumed as the reference population. The average pedigree completeness index for one generation back was 95.9%, 97.4%, 91.2%, 89.8%, and 94.2% for appropriate breeds. Number of ancestors explaining 100% of gene pool was 186, 373, 125, 157, and 37 in CLA, CLWd, CLWs, DC, and PN, respectively. The relative proportion of inbred animals (58%, 58%, 54%, 47%, and 25%, the average inbreeding (2.7%, 1.4%, 2.5%, 3.6%, and 1.3% and the average co-ancestry (3.1%, 1.6%, 3.3%, 4.2%, and 3.3% were found over the past decade in analysed breeds. The expected inbreeding under random mating increased during the last 10 years in CLWs and PN and varied from 1.27% to 3.2%. The effective population size computed on the basis of inbreeding was 76, 74, 50, 35, and 83 in 2012 in CLA, CLWd, CLWs, DC, and PN, respectively. The shortest generation interval (1.45 was observed for CLWd in sire to son selection pathway. The longest generation interval obtained PN (1.95 in sire to daughter pathway. The average relative GD loss within last generation interval was 7.05%, 4.70%, 9.81%, 7.47%, and 10.46%, respectively. The relative proportion of GD loss due to genetic drift on total GD loss was 85.04%, 84.51%, 89.46%, 86.19%, and 83.68% in CLA, CLWd, CLWs, DC, and PN, respectively. All breeds were characterized by a high proportion of inbred animals, but the average inbreeding was low. The most vulnerable breeds to loss of GD are DC and PN. Therefore, a breeding program should be more oriented to prevent the increase of GD loss in these

    Full Text Available This Analysis and Design of Algorithm is considered as a compulsory course in the field of Computer Science. It increases the logical and problem solving skills of the students and make their solutions efficient in terms of time and space.  These objectives can only be achieved if a student practically implements what he or she has studied throughout the course. But if the contents of this course are merely studied and rarely practiced then the actual goals of the course is not fulfilled. This article will explore the extent of practical implementation of the course of analysis and design of algorithm. Problems faced by the computer science community and major barriers in the field are also enumerated. Finally, some recommendations are made to overcome the obstacles in the practical implementation of analysis and design of algorithms.

    Conservation management in the North Sea is often motivated by the population size of marine mammals, like harbor porpoises Phocoena phocoena. In the Dutch part of the North Sea, sighting and stranding data are used to estimate population sizes, but these data give little insight into genetic structuring of the population. In this study we investigated genetic structure among animals stranded at different locations and times of year. We also tested whether there is a link between stranding and necropsy data, and genetic diversity. We made use of both mitochondrial (mtDNA) and microsatellite DNA analysis of samples from dead stranded porpoises along the Dutch coast during 2007. mtDNA analysis showed 6 variable positions in the control region, defining 3 different haplotypes. mtDNA haplotypes were not randomly distributed along the Dutch coastline. However, microsatellite analysis showed that these mtDNA haplotypes did not represent separate groups on a nuclear level. Furthermore, microsatellite analysis revealed no genotypic differences between seasons, locations or genders. The results of this study indicate that the Dutch population is panmictic. In contrast, heterozygosity levels were low, indicating some level of inbreeding in this population. However, this was not corroborated by other indices of inbreeding. This research provided insight into genetic structuring of stranded porpoises in 2007, but data from multiple years should be included to be able to help estimate population sizes.

    The aim of the study is to obtain more insight into the possible association between consanguinity and the incidence of deliberate self-burning. Data were obtained by analysis of medical records of patients hospitalized in two referral burn centers: Chormy Burn Center (Bushehr Province, south of Iran) from March 21, 1998, through March 20, 2004, and Shahid Sadoqi Center of Burns and Injuries (Yazd Province, center of Iran) from March 21, 2000, through March 20, 2004. The incidence of suicidal burns was 6.51 and 2.32/100,000 person-years for Bushehr and Yazd Provinces, respectively. The observed sex ratio of patients in both centers indicated there was a female predominance in patients with self-inflicted burns. Using patients' home addresses, patients were sorted into 16 cities. The incidence of suicide by self-burning ranged from 0.80 (for Tabas, located in Yazd Province) to 12.60/100,000 person-years (for Dilam, located in Bushehr Province). The coefficient of inbreeding defines the probability that an individual received both alleles of a pair from an identical ancestral source. There was a significant correlation between incidences of suicidal burns and mean coefficient of inbreeding (r = 0.782, df = 14, p < 0.001). In addition to other factors, consanguineous marriage may be a risk factor that influences the incidence of suicidal burns in a population.

  2. Fitness consequences of outcrossing in a social spider with an inbreeding mating system.

    2014-02-01

    Inbreeding mating systems are uncommon because of inbreeding depression. Mating among close relatives can evolve, however, when outcrossing is constrained. Social spiders show obligatory mating among siblings. In combination with a female-biased sex ratio, sib-mating results in small effective populations. In such a system, high genetic homozygosity is expected, and drift may cause population divergence. We tested the effect of outcrossing in the social spider Stegodyphus dumicola. Females were mated to sib-males, to a non-nestmate within the population, or to a male from a distant population, and fitness traits of F1s were compared. We found reduced hatching success of broods from between-population crosses, suggesting the presence of population divergence at a large geographical scale that may result in population incompatibility. However, a lack of a difference in offspring performance between inbred and outbred crosses indicates little genetic variation between populations, and could suggest recent colonization by a common ancestor. This is consistent with population dynamics of frequent colonizations by single sib-mated females of common origin, and extinctions of populations after few generations. Although drift or single mutations can lead to population divergence at a relatively short time scale, it is possible that dynamic population processes homogenize these effects at longer time scales. © 2013 The Author(s).

    1978-01-01

    In order to establish relationships among immigration, inbreeding, and age at marriage in urban and rural zones in Chile, and to formulate an endogamy index, ecclesiastical and civil data on consanguinity from 1865-1914 were analyzed, and a random mating deviation index was developed, with resulting values indicating deviation toward endogamy in both zones. Data grouped by zones and decades include means of population and density, nuptiality, consanguineous marriages (number, types, frequencies, and inbreeding coefficients), and frequencies of immigrants among consanguineous and nonconsanguineous couples. All of these values differ markedly between zones, with values in the rural zone double those in the urban zone. In the 2 zones, there are no clear differences in age at marriage between consanguineous and nonconsanguineous couples, and this is an important finding. From the point of view of fertility, one can expect a similar length period of fertility for both groups of couples. In this case, lower fertility might be expected in consanguineous marriages, only because of a higher probability of homozygosis of deleterious genes.

    The Hirsch index (h-index) has been shown to correlate with radiation oncology residents' having a first job in academics versus private practice, but it is limited by its inability to distinguish between the differing significance of coauthor roles in articles. A list of 2016 radiation oncology resident graduates and their postresidency career choices was compiled. The Scopus bibliometric citation database was then searched to collect h-index data for articles limited to first author only (h f ) and first or second-author only (h s ) for each resident. Mean h f was 2.06 for all resident graduates, and mean h s was 2.77. Residents with PhDs had significantly higher h f (3.11 versus 1.76, P gender. Only 10% of graduates without any first- and/or second-author articles cited at least once secured academic jobs. These findings indicate that stratifying publications by first or second authorship when developing benchmarks for evaluating resident productivity and postresidency career type may be useful.

    Shifts in weed species composition and richness resulting from near-exclusive reliance on herbicides in glyphosate-resistant (GR) cropping systems has necessitated the implementation of alternative weed management tactics to reduce selection pressures of herbicides. We contrasted the response of the weed soil seedbank to effects of weed management strategy, comparing grower practices with academic recommendations for best management practices (BMPs) over 6 years and across five weed hardiness zones in the US Midwest at sites subject to GR cropping systems. Total weed population density and species richness varied according to cropping system, location and prior year's crop, but less so to weed management strategy. The seedbank population density for 11 of the 14 most frequent weed species was affected by weed management strategy either alone or in an interaction with hardiness zone or year, or both. In only 29% of comparisons was weed population density lower following academic recommendations, and this depended upon prior crop and cropping system. The population density of high-risk weed species was reduced by academic recommendations, but only in two of six years and under continuous GR maize. Overall, the weed population density was decreasing in field halves subject to the BMPs in the academic recommendations relative to grower practices. The soil seedbank is slow to respond to academic recommendations to mitigate glyphosate-resistant weeds, but represents a biological legacy that growers need to keep in mind even when management practices reduce emerged field weed population densities. © 2015 Society of Chemical Industry.

    2011-01-01

    We studied inbreeding depression, growth context and maternal influence as constraints to fitness in the self-compatible, protandrous Dianthus guliae Janka, a threatened Italian endemic. We performed hand-pollinations to verify outcomes of self- and cross-fertilisation over two generations, and grew inbred and outbred D. guliae offspring under different conditions - in pots, a common garden and field conditions (with/without nutrient addition). The environment influenced juvenile growth and flowering likelihood/rate, but had little effect on inbreeding depression. Significant interactions among genetic and environmental factors influenced female fertility. Overall, genetic factors strongly affected both early (seed mass, seed germination, early survival) and late (seed/ovule ratio) life-history traits. After the first pollination experiment, we detected higher mortality in the selfed progeny, which is possibly a consequence of inbreeding depression caused by over-expression of early-acting deleterious alleles. The second pollination induced a strong loss of reproductive fitness (seed production, seed mass) in inbred D. guliae offspring, regardless of the pollination treatment (selfing/crossing); hence, a strong (genetic) maternal influence constrained early life-history traits of the second generation. Based on current knowledge, we conclude that self-compatibility does not prevent the detrimental effects of inbreeding in D. guliae populations, and may increase the severe extinction risk if out-crossing rates decrease. © 2010 German Botanical Society and The Royal Botanical Society of the Netherlands.

    Full Text Available The protected cultivation technology, through which the various inbred generations with the combination of economic valuable traits and different level of sterility can be produced, is used in order to accelerate the breeding program. However, there is a negative effect of inbreeding depression and self-incompatibility can often occur and cause the loss of valuable breeding forms. The aim of the work was to study the influence of steroidal glycosides capsicoside (SGC on exhibition of CMS, and morphobiological parameters of 13 inbred generations that were produced from fertile plant and partly sterile plants with level of sterility 10% and 50%. The seeds were soaked for 24 hours in water solution of SGC with concentration 10-3%, and in water control. Then the seeds were dried up and sown in the greenhouse. The stecklings and roots obtained were vernalized at 3-5Co. Mother plants were grown under 18 hour photoperiod in greenhouse with supplementary lighting. Inbreeding seeds were obtained in individual cloth isolators. It was shown that for all generations the treatment with SGC improved the seed germination (4-8% more, increased the root index and its length (12-24% more, decreased betanin content (22-48% less in comparison with control. The action of SGC on the other morphological and biochemical traits such as height of leaf rosette, leaf number, plant and root weight, head size, number of generative buds, and nitrate content was defined by the level of sterility of mother plant. The most expressed effect for all traits mentioned was seen in inbreeding generations of sterile plants with high level of sterility. After action effect of seed treatment with SGC on development of seed plants from inbreeding generations, not depending on sterility level of mother plants, showed the positive influence on plant habitus of seed mother plants, decreasing the plant height, but increasing stem number and functional parameters of microgametophyte in fertile

    Full Text Available Abstract Background Understanding the mechanisms that control species genetic structure has always been a major objective in evolutionary studies. The association between genetic structure and species attributes has received special attention. As species attributes are highly taxonomically constrained, phylogenetically controlled methods are necessary to infer causal relationships. In plants, a previous study controlling for phylogenetic signal has demonstrated that Wright's FST, a measure of genetic differentiation among populations, is best predicted by the mating system (outcrossing, mixed-mating or selfing and that plant traits such as perenniality and growth form have only an indirect influence on FST via their association with the mating system. The objective of this study is to further outline the determinants of plant genetic structure by distinguishing the effects of mating system on gene flow and on genetic drift. The association of biparental inbreeding and inbreeding depression with population genetic structure, mating system and plant traits are also investigated. Results Based on data from 263 plant species for which estimates of FST, inbreeding (FIS and outcrossing rate (tm are available, we confirm that mating system is the main influencing factor of FST. Moreover, using an alternative measure of FST unaffected by the impact of inbreeding on effective population size, we show that the influence of tm on FST is due to its impact on gene flow (reduced pollen flow under selfing and on genetic drift (higher drift under selfing due to inbreeding. Plant traits, in particular perenniality, influence FST mostly via their effect on the mating system but also via their association with the magnitude of selection against inbred individuals: the mean inbreeding depression increases from short-lived herbaceous to long-lived herbaceous and then to woody species. The influence of perenniality on mating system does not seem to be related to

    The distribution of genetic variability from the interior towards the periphery of a species' range is of great interest to evolutionary biologists. Although it has been long presumed that population genetic variation should decrease as a species' range is approached, results of empirical investigations still remain ambiguous. Knowledge regarding patterns of genetic variability as well as affected factors is particularly not conclusive in plants. To determine genetic divergence in peripheral populations of the wild rice Oryza rufipogon Griff. from China, genetic diversity and population structure were studied in five northern & northeastern peripheral and 16 central populations using six microsatellite loci. We found that populations resided at peripheries of the species possessed markedly decreased microsatellite diversity than those located in its center. Population size was observed to be positively correlated with microsatellite diversity. Moreover, there are significantly positive correlations between levels of microsatellite diversity and distances from the northern and northeastern periphery of this species. To investigate genetic structure and heterozygosity variation between generations of O. rufipogon, a total of 2382 progeny seeds from 186 maternal families were further assayed from three peripheral and central populations, respectively. Peripheral populations exhibited significantly lower levels of heterozygosities than central populations for both seed and maternal generations. In comparisons with maternal samples, significantly low observed heterozygosity (HO) and high heterozygote deficit within populations (FIS) values were detected in seed samples from both peripheral and central populations. Significantly lower observed heterozygosity (HO) and higher FIS values were further observed in peripheral populations than those in central populations for seed samples. The results indicate an excess of homozygotes and thus high inbreeding depression in

    To study the genetic potential, heterotic effects and inbreeding depression, 8 X 8 F/sub 2/diallel populations with parental lines of upland cotton were grown during crop season 2010 in a randomized complete block design at Khyber Pakhtunkhwa Agricultural University Peshawar, Pakistan. Highly significant ( p = 0.01 ) variations were noticed among parental lines and F/sub 2/ populations for all the traits. According to genotypes mean performance for various traits, plant height varied from 101.60 to 126.30 cm and 98.60 to 140.60 cm, bolls plant/sup -1/ (12.87 to 19.53; 12.13 to 22.60), boll weight (3.80 to 5.01 g; 3.04 to 5.38 g) and seed cotton yield plant/sup -1/ varied from 55.74 to 85.47 g and 45.57 to 96.05 g in parental cultivars and their F/sub 2/ populations, respectively. However, 12 and 7 F/sub 2/ populations manifested significant heterosis over mid and better parents for plant height, 7 and 3 for bolls plant/sup -1/, 13 and 9 for boll weight and 13 and 5 F/sub 2/ populations for seed cotton yield plant/sup -1/, respectively. F/sub 2/ populations i.e. CIM-554 X CIM-473, CIM-554 X CIM-499, CIM-496 X SLH-284, CIM-473 X CIM-446 and CIM-554 X SLH-284 with low mean values for plant height performed better and manifested highly significant heterotic values over mid and better parents for bolls per plant, boll weight and seed cotton yield. By comparing F/sub 2/ mean values with F/sub 1/s, inbreeding depression was observed for plant height (0.66 to 23. 99%), bolls per plant (5.00 to 63.16%), boll weight (0.20 to 23.24%) and seed cotton yield (0.44 to 75.52%). However, 62% of F/sub 2/ populations revealed negative values for inbreeding depression, 14% for bolls per plant, 77% for boll weight and 21% for yield, revealed that these F/sub 2/ populations were more stable and performed better than F/sub 1/s even after segregation. Although, F/sub 2/ populations may display less heterosis as compared to F/sub 1/, but still better than high parents and can be used as

    In this paper, the structure of a southeastern Spanish population was studied for the first time with respect to its inbreeding patterns and its relationship with demographic and geographic factors. Data on consanguineous marriages (up to second cousins) from 1900 to 1969 were taken from ecclesiastic dispensations. Our results confirm that the patterns and trends of inbreeding in the study area are consistent with those previously observed in most non-Cantabrian Spanish populations. The rate of consanguineous marriages was apparently stable between 1900 and 1935 and then sharply decreased since 1940, which coincides with industrialization in Spain. A marked departure from Hardy-Weinberg expectations (0.25) in the ratio of first cousin (M22) to second cousin (M33) marriages in the study population (0.88) was observed. The high levels of endogamy (>80%) and its significant steadiness throughout the twentieth century is noteworthy. Accordingly, our results show that exogamous marriages were not only poorly represented but also that this reduced mobility (relationships between population size and consanguinity rates and inbreeding fit power-law distributions. A significant positive correlation was observed between inbreeding and elevation. Many Spanish populations have experienced a prolonged and considerable isolation across generations, which has led to high proportions of historical and local endogamy that is associated, in general, with high [Formula: see text] values. Thus, assessing genomic inbreeding using runs of homozygosity (ROH) in current Spanish populations could be an additional pertinent strategy for obtaining a more refined perspective regarding the population history inferred from the extent and frequency of ROH regions.

    Documentation should ideally occur in real time immediately after completion of a service. Although electronic records often do not print the time that documentation notes were entered on the medical record, automated anesthesia record keeping systems store an audit trail that time stamps events entered by all anesthesia providers. As more lawyers become aware of this fact and requisition audit trails, prospective charting of necessary documentation may undermine the integrity of an anesthesia care team accused of malpractice, with potentially significant medicolegal consequences. We changed existing documentation practices of a large academic practice via a three-step process. Educational sessions increased the percentage of cases with correct timing of emergence documentation from 25% to 60% over a 2-mo period. Automated email performance feedback further increased correct note timing to 70%. When combined with personal contact by a member of the billing office and email copy notification of the chair, the percentage increased to >99.5%. The behavioral change was seen in all individuals, as 95% of attendings had < or = 2 records/mo with untimely documentation at the end of the study period. Once the habits were ingrained, further input was rarely necessary over the next 9 mo. This suggests physician behavioral change related to work process flow, unlike that related to patient care, is easily sustained.

  20. Strong inbreeding depression and individually variable mating system in the narrow endemic Erodium cazorlanum (Geraniaceae

    2013-06-01

    Full Text Available Angiosperms evolved different systems to attract effective pollinators while reducing selfing in hermaphroditic flowers. Selfing ability can be advantageous when pollinators and/or mates are scarce, although inbreeding depression may largely reduce those advantages. Recent comparative analyses suggested endemic species tend to evolve self-compatibility but a better understanding of the associated reproductive and genetic tradeoffs is required. Experimental hand-pollinations under greenhouse conditions were conducted to investigate the selfing ability and estimate inbreeding depression up to the offspring’ first reproductive event in Ero dium cazorlanum, a narrow endemic species restricted to dolomite outcrops in SE Spanish mountains. We found autonomous selfing ineffective. Further, when experimentally applied, pollen of the same flower produced significantly fewer fruits and seeds compared to geitonogamous and cross pollinations. The number of seeds per fruit was significantly higher after cross pollinations and strong inbreeding depression accumulated through the life-cycle. Interestingly, individual plants exhibited broad variation in selfing ability with six out of 14 individuals producing no seed after geitonogamy. Understanding the consequences of individual variation in self compatibility deserves further investigation in the field now that we know that strong inbreeding depression may limit recruitment of selfed progeny.Las Angiospermas han desarrollado diversos sistemas para atraer polinizadores eficientes y al mismo tiempo reducir la posibilidad de autopolinización asociada al hermafroditismo. La capacidad de autopolinización puede ser ventajosa en situaciones de escasez de polinizadores y/o individuos reproductores, beneficios que pueden reducirse ampliamente a causa de la depresión por endogamia. Análisis filogenéticos recientes indicaron que las especies endémicas tienden a presentar sistemas de autocompatibilidad, por tanto

    There are a number of sources available to prescribers to stay up to date about medicines. Prescribers in rural areas in developing countries however, may not able to access some of them. Interventions to improve prescribing can be educational, managerial, and regulatory or use a mix of strategies. Detailing by the pharmaceutical industry is widespread. Academic detailing (AD) has been classically seen as a form of continuing medical education in which a trained health professional such as a physician or pharmacist visits physicians in their offices to provide evidence-based information. Face-to-face sessions, preferably on an individual basis, clear educational and behavioural objectives, establishing credibility with respect to objectivity, stimulating physician interaction, use of concise graphic educational materials, highlighting key messages, and when possible, providing positive reinforcement of improved practices in follow-up visits can increase success of AD initiatives. AD is common in developed countries and certain examples have been cited in this review. In developing countries the authors have come across reports of AD in Pakistan, Sudan, Argentina and Uruguay, Bihar state in India, Zambia, Cuba, Indonesia and Mexico. AD had a consistent, small but potentially significant impact on prescribing practices. AD has much less resources at its command compared to the efforts by the industry. Steps have to be taken to formally start AD in Nepal and there may be specific hindering factors similar to those in other developing nations.

    The objective of this study was to analyse genetic diversity for the three scent-hound breeds Bavarian mountain hound (BMH), Hanoverian hound (HH) and Tyrolean hound (TH) using all available pedigree information from scent-hound kennel clubs for these three breeds throughout Europe. The pedigree data of the BMH and the HH date back to 1912 and 1894, respectively. Pedigree data of the TH were available from the 1960s onwards. The reference populations included all BMH (n = 3231), HH (n = 1371) and TH (n = 1167) dogs registered between 1992 and 2004. Average generation intervals were 5.3 years for the BMH and 5.0 years for the HH and TH. Average inbreeding coefficients for the reference populations were 4.5%, 6.8% and 9.5% for the BMH, HH and TH. The effective numbers of founders, ancestors and founder genomes were lowest for the TH and highest for the BMH. The effective numbers of founder genomes were 10.9, 5.6 and 4.3 for the BMH, HH and TH. Effective population size was largest for the BMH with 72.7 effective breeding animals, followed by the HH with 50.9 and TH with 26.5. The most important ten ancestors had genetic contributions to the reference populations of 54.4%, 65.2% and 77.9% in the BMH, HH and TH. The results of our study indicate the need for careful breed management in these highly specialized hound breeds to maintain genetic diversity. European stud books should be established for these dog breeds in order to avoid inbreeding due to missing pedigree records.

The present study used simulation to investigate the level of genetic gain and inbreeding obtained from GS breeding strategies compared with traditional breeding strategies for key traits (persistency, yield, and flowering time. Base population genomes were simulated through random mating for 60,000 generations at an effective population size of 10,000. The degree of linkage disequilibrium (LD in the resulting population was compared with that obtained from empirical studies. Initial parental varieties were simulated to match diversity of current commercial cultivars. Genomic selection was designed to fit into a company breeding program at two selection points in the breeding cycle (spaced plants and miniplot. Genomic estimated breeding values (GEBVs for productivity traits were trained with phenotypes and genotypes from plots. Accuracy of GEBVs was 0.24 for persistency and 0.36 for yield for single plants, while for plots it was lower (0.17 and 0.19, respectively. Higher accuracy of GEBVs was obtained for flowering time (up to 0.7, partially as a result of the larger reference population size that was available from the clonal row stage. The availability of GEBVs permit a 4-yr reduction in cycle time, which led to at least a doubling and trebling genetic gain for persistency and yield, respectively, than the traditional program. However, a higher rate of inbreeding per cycle among varieties was also observed for the GS strategy.

    Inefficient patient throughput in a surgery practice can result in extended new patient backlogs, excessively long cycle times in the outpatient clinics, poor patient satisfaction, decreased physician productivity, and loss of potential revenue. This project assesses the efficacy of multiple throughput interventions in an academic, plastic surgery practice at a public university. We implemented a Patient Access and Efficiency (PAcE) initiative, funded and sponsored by our health care system, to improve patient throughput in the outpatient surgery clinic. Interventions included: (1) creation of a multidisciplinary team, led by a project redesign manager, that met weekly; (2) definition of goals, metrics, and target outcomes; 3) revision of clinic templates to reflect actual demand; 4) working down patient backlog through group visits; 5) booking new patients across entire practice; 6) assigning a physician's assistant to the preoperative clinic; and 7) designating a central scheduler to coordinate flow of information. Main outcome measures included: patient satisfaction using Press-Ganey surveys; complaints reported to patient relations; time to third available appointment; size of patient backlog; monthly clinic volumes with utilization rates and supply/demand curves; "chaos" rate (cancellations plus reschedules, divided by supply, within 48 hours of booked clinic date); patient cycle times with bottleneck analysis; physician productivity measured by work Relative Value Units (wRVUs); and downstream financial effects on billing, collection, accounts receivable (A/R), and payer mix. We collected, managed, and analyzed the data prospectively, comparing the pre-PAcE period (6 months) with the PAcE period (6 months). The PAcE initiative resulted in multiple improvements across the entire plastic surgery practice. Patient satisfaction increased only slightly from 88.5% to 90.0%, but the quarterly number of complaints notably declined from 17 to 9. Time to third

    This article assesses parental confidence and current behavioral techniques used by mostly African American caregivers of young children in an urban Southeastern setting, including their use and attitudes toward corporal punishment (CP). Two hundred and fifty parental participants of children aged 18 months to 5 years completed a survey on factors affecting their behavioral management and views on CP. Statistical analysis included χ 2 test and logistic regression with confidence interval significance determined at P <.05. Significant associations of CP usage were found in parents who were themselves exposed to CP and parental level of frustration with child disobedience. A total of 40.2% of respondents answered that they had not received any discipline strategies from pediatricians and 47.6% were interested in receiving more behavioral strategies. Clear opportunities exist for pediatricians to provide information on evidence-based disciplinary techniques, and these discussions may be facilitated through the creation of a No Hit Zone program in the pediatric practice.

    Sepsis is a potentially life-threatening condition that requires urgent management in an Emergency Department (ED). Evidence-based guidelines for managing sepsis have been developed; however, their integration into routine practice is often incomplete. Care maps may help clinicians meet guideline targets more often. To determine if electronic clinical practice guidelines (eCPGs) improve management of patients with severe sepsis and septic shock (SS/SS). The impact of an eCPG on the management of patients presenting with SS/SS over a 3-year period at a tertiary care ED was evaluated using retrospective case-control design and chart review methods. Cases and controls, matched by age and sex, were chosen from an electronic database using physician sepsis diagnoses. Data were compared using McNemar tests or paired t-tests, as appropriate. Overall, 51 cases and controls were evaluated; the average age was 62 years, and 60% were male. eCPG patients were more likely to have a central venous pressure and central venous oxygen saturation measured; however, lactate measurement, blood cultures, and other investigations were similarly ordered (all p > 0.05). The administration of antibiotics within 3 h (63% vs. 41%; p = 0.03) and vasopressors (45% vs. 20%; p = 0.02) was more common in the eCPG group; however, use of corticosteroids and other interventions did not differ between the groups. Overall, survival was high and similar between groups. A sepsis eCPG experienced variable use; however, physicians using the eCPG achieved more quality-of-care targets for SS/SS. Strategies to increase the utilization of eCPGs in Emergency Medicine seem warranted. Copyright © 2013 Elsevier Inc. All rights reserved.

    In 2008, the Centers for Medicare and Medicaid Services (CMS) established nonpayment policies resulting from costliness of hospital-acquired pressure ulcers (HAPUs) to hospitals. This prompted hospitals to adopt quality improvement (QI) interventions that increase use of evidence-based practices (EBPs) for HAPU prevention. To evaluate the longitudinal impact of CMS policy and QI adoption on HAPU rates. We characterized longitudinal adoption of 25 QI interventions that support EBPs through hospital leadership, staff, information technology, and performance and improvement. Quarterly counts of HAPU incidence and inpatient characteristics were collected from 55 University HealthSystem Consortium hospitals between 2007 and 2012. Mixed-effects regression models tested the longitudinal association of CMS policy, HAPU coding, and QI on HAPU rates. The models assumed level-2 random intercepts and random effects for CMS policy and EBP implementation to account for between-hospital variability in HAPU incidence. Controlling for all 25 QI interventions, specific updates to EBPs for HAPU prevention had a significant, though modest reduction on HAPU rates (-1.86 cases/quarter; P=0.002) and the effect of CMS nonpayment policy on HAPU prevention was much greater (-11.32 cases/quarter; P<0.001). HAPU rates were significantly lower after changes in CMS reimbursement. Reductions are associated with hospital-wide implementation of EBPs for HAPU prevention. Given that administrative data were used, it remains unknown whether these improvements were due to changes in coding or improved quality of care.

    Needlestick injury prevalence, protection practices, and attitudes were assessed. Current medical students were compared with 2003 data to assess any changes that occurred with engineered safety feature implementation. Risk of occupational exposure to bloodborne pathogens is elevated in the operating room particularly with surgeons in training and nurses. A cross-sectional survey was distributed to medical students (n = 358) and Department of Surgery staff (n = 247). The survey response rate was 24.8%. Needlestick injuries were reported by 38.7% of respondents (11% high risk), and the most common cause was "careless/accidental." Needlestick injury prevalence increased from medical students to residents and fellows (100%). Thirty-three percent of injured personnel had at least one unreported injury, and the most common reason was "inconvenient/too time consuming." Needlestick injury prevalence and double-glove use in medical students did not differ from 2003, and 25% of fellows reported always wearing double gloves. The true seroconversion rate for bloodborne pathogens was underestimated or unknown. The concern for contracting a bloodborne pathogen significantly decreased (65%) compared to 2003, and there were significantly less medical students with hepatitis B vaccinations (78.3%). Level of concern for contracting a bloodborne pathogen was predictive of needlestick injury. Needlestick injury and occupational exposure to bloodborne pathogens are significant hazards for surgeons and nurses. Attitudes regarding risk are changing, and the true seroconversion risk is underestimated. Educational efforts focused on needlestick injury prevalence, seroconversion rates, and double-glove perforation rates may be effective in implementing protective strategies.

    genetically diverse female lines of sunflower were crossed with male testers to get heterotic hybrids. studies were carried-out during 2008-2010 at experiment filed of agriculture research institute, tandojam, sindh, pakistan. six female lines like t-4-0319, pac-0505, ho-i, hysun-33, peshawar-93 and cms-03 and three testers i.e., pac-0306, pac-64-a and sf-187 were crossed in a line * tester mating design, thus 18 f1 and f2 hybrids were developed for evaluation of heterosis and inbreeding depression for days to initial flowering, days to maturity, leaves/plant, plant height (cm), head diameter (cm), 1000-achene weight (g), seed yield kg/ha and oil yield kg/ha. the experiment was conducted in a randomised completeb lock design with four replications. the analysis of variance revealed significant differences among parents, f1s and f2 hybrids for all the traits studied. the existence of significant genetic variability among the plant traits is particularly useful because variations in these traits would allow further improvement in sunflower seed yield and oil traits. the f1 hybrids ho-i * pac-0306 and ho-i pa * c-64-a exhibited desirable negative mid and better parent heterosis for days to initial flowering, days to maturity and plant height. these hybrids also manifested desirable positive heterotic effects for leaves/plant, head diameter, 1000-achene.s weight, seed yield and oil yield. inbreeding depression for phenological, seed yield and oil traits showed that desirable high inbreeding depression was observed in hybrids ho-i * p*ac-64-a, ho-i * pac-0306 and ho-i * sf-187 for days to initial flowering, similarly t-4-0319 * pac-0306, pac-0505 ± sf-187 and ho-i * pac-64-a explicated maximum but rewarding inbreeding depression for days to maturity. the f2 hybrids hysun-33 * sf-187 and peshawer-93 * pac-64-a may be the most desirable ones in the sense that they recorded comparatively moderate inbreeding depression with enough number of leaves to be productive if f2

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

  13. The ABCs of an evolutionary education science: The academic, behavioral, and cultural implications of an evolutionary approach to education theory and practice

    Kauffman, Rick, Jr.

    Calls for improving research-informed policy in education are everywhere. Yet, while there is an increasing trend towards science-based practice, there remains little agreement over which of the sciences to consult and how to organize a collective effort between them. What Education lacks is a general theoretical framework through which policies can be constructed, implemented, and assessed. This dissertation submits that evolutionary theory can provide a suitable framework for coordinating educational policies and practice, and can provide the entire field of education with a clearer sense of how to better manage the learning environment. This dissertation explores two broad paths that outline the conceptual foundations for an Evolutionary Education Science: "Teaching Evolution" and "Using Evolution to Teach." Chapter 1 introduces both of these themes. After describing why evolutionary science is best suited for organizing education research and practice, Chapter 1 proceeds to "teach" an overview of the "evolutionary toolkit"---the mechanisms and principles that underlie the modern evolutionary perspective. The chapter then employs the "toolkit" in examining education from an evolutionary perspective, outlining the evolutionary precepts that can guide theorizing and research in education, describing how educators can "use evolution to teach.". Chapters 2-4 expand on this second theme. Chapters 2 and 3 describe an education program for at-risk 9th and 10th grade students, the Regents Academy, designed entirely with evolutionary principles in mind. The program was rigorously assessed in a randomized control design and has demonstrated success at improving students' academic performance (Chapter 2) and social & behavioral development (Chapter 3). Chapter 4 examines current teaching strategies that underlie effective curriculum-instruction-assessment practices and proposes a framework for organizing successful, evidence-based strategies for neural

    Correlation exists between people who engage in academic dishonesty as students and unethical behavior once in practice. Previously, we assessed the attitudes of general surgery residents and ethical practices in test taking at a single institution. Most residents had not participated in activities they felt were unethical, yet what constituted unethical behavior was unclear. We sought to verify these results in a multi-institutional study. A scenario-based survey describing potentially unethical activities related to the American Board of Surgery In-training Examination (ABSITE) was administered. Participants were asked about their knowledge of or participation in the activities and whether the activity was unethical. Program directors were surveyed about the use of ABSITE results for resident evaluation and promotion. Ten programs participated in the study. The resident response rate was 67% (186/277). Of the respondents, 43% felt that memorizing questions to study for future examinations was unethical and 50% felt that using questions another resident memorized was unethical. Most felt that buying (86%) or selling (79%) questions was unethical. Significantly more senior than junior residents have memorized (30% vs 16%; p = 0.04) or used questions others memorized (33% vs 12%; p = 0.002) to study for future ABSITE examinations and know of other residents who have done so (42% vs 20%; p = 0.004). Most programs used results of the ABSITE in promotion (80%) and set minimum score expectations and consequences (70%). Similar to our single-institution study, residents had not participated in activities they felt to be unethical; however the definition of what constitutes cheating remains unclear. Differences were identified between senior and junior residents with regard to memorizing questions for study. Cheating and unethical behavior is not always clear to the learner and represents an area for further education. © 2013 Association of Program Directors in Surgery

    In 2008, the U.S. Centers for Medicare and Medicaid Services enacted a nonpayment policy for stage III and IV hospital-acquired pressure ulcers (HAPUs), which incentivized hospitals to improve prevention efforts. In response, hospitals looked for ways to support implementation of evidence-based practices for HAPU prevention, such as adoption of quality improvement (QI) interventions. The objective of this study was to quantify adoption patterns of QI interventions for supporting evidence-based practices for HAPU prevention. This study surveyed wound care specialists working at hospitals within the University HealthSystem Consortium. A questionnaire was used to retrospectively describe QI adoption patterns according to 25 HAPU-specific QI interventions into four domains: leadership, staff, information technology (IT), and performance and improvement. Respondents indicated QI interventions implemented between 2007 and 2012 to the nearest quarter and year. Descriptive statistics defined patterns of QI adoption. A t-test and statistical process control chart established statistically significant increase in adoption following nonpayment policy enactment in October 2008. Increase are described in terms of scope (number of QI domains employed) and scale (number of QI interventions within domains). Fifty-three of the 55 hospitals surveyed reported implementing QI interventions for HAPU prevention. Leadership interventions were most frequent, increasing in scope from 40% to 63% between 2008 and 2012; "annual programs to promote pressure ulcer prevention" showed the greatest increase in scale. Staff interventions increased in scope from 32% to 53%; "frequent consult driven huddles" showed the greatest increase in scale. IT interventions increased in scope from 31% to 55%. Performance and improvement interventions increased in scope from 18% to 40%, with "new skin care products . . ." increasing the most. Academic medical centers increased adoption of QI interventions

    The constructs of academic entitlement and student consumerism refer to students' attitudes toward education as a commodity and the underlying belief that as consumers, they should be catered to and given the opportunity to participate in the education process according to their preferences. Most discussions regarding these attitudes are anecdotal, but the pervasiveness of these accounts and the troubling effects that ensue warrant attention. Grade inflation, student incivility, altered classroom practices, and decreased faculty morale are all potential aftereffects of teaching students who hold academic entitlement beliefs. Numerous factors are posited as attributing to academic entitlement including personal issues, societal pressures, and broad academic practices. This paper discusses these factors and offers faculty members and administrators recommendations regarding practices that may curb or alleviate issues associated with academically entitled students.

    Full Text Available A total of 1551 normal lactation records of Egyptian buffaloes, Kept at Mehallet Mousa Farm, belonging to Ministry of Agriculture, during the period from 1960 to 2001 were used. Milk yield, lactation period and age at first calving were studied in order to determine the presence of inbreeding in the herd and to evaluate it is effects as well as the effects of some environmental factors on these traits. In addition, genetic parameters of these traits are also studied. Milk yield, lactation period and age at first calving averaged 1193 ± 522 kg, 282±125 and 39 ± 3 mo, respectively. Among all three traits, only age at first calving was affected by inbreeding. Month of calving and year of calving had a significant effect on all traits studied, while age at first calving had no significant effect on milk yield and lactation period.

    We tested the hypothesis that sex-biased natal dispersal reduces close inbreeding in American black bears, a solitary species that exhibits nearly complete male dispersal and female philopatry. Using microsatellite DNA and spatial data from reproductively mature bears (>or= 4 years old), we examined the spatial genetic structure of two distinct populations in New Mexico from 1993 to 2000. As predicted, relatedness (r) and the frequency of close relationships (parent-offspring or full siblings) decreased with distance among female dyads, but little change was observed among male or opposite-sex dyads. Neighbouring females were more closely related than neighbouring males. The potential for inbreeding was low. Most opposite-sex pairs that lived sufficiently close to facilitate mating were unrelated, and few were close relatives. We found no evidence that bears actively avoided inbreeding in their selection of mates from this nearby pool, as mean r and relationship frequencies did not differ between potential and actual mating pairs (determined by parentage analysis). These basic patterns were apparent in both study areas despite a nearly two-fold difference in density. However, the sex bias in dispersal was less pronounced in the lower-density area, based on proportions of bears with male and female relatives residing nearby. This result suggests that male bears may respond to reduced competition by decreasing their rate or distance of dispersal. Evidence supports the hypothesis that inbreeding avoidance is achieved by means of male-biased dispersal but also indicates that competition (for mates or resources) modifies dispersal patterns.

    Introduction Fatigue is a common symptom in RA and used as an outcome measure in RA clinical trials. We studied a large academic clinical practice to estimate the minimally important difference (MID) for a fatigue visual analog scale using patient-reported anchors (fatigue, pain and overall health). Methods RA patients (N=307) had clinic visits at 2 time points at a median of 5.9 months apart. They completed fatigue visual analog scale (VAS; 0–10) and retrospective anchor items, “How would you describe your overall fatigue/pain/overall health since the last visit?” Much worsened, Somewhat worsened, Same, Somewhat better, or Much better. The fatigue anchor was used for primary analysis and the pain/ overall health anchors for sensitivity analyses. The minimally changed group was defined by those reporting they were somewhat better or somewhat worsened. Results The mean (SD) age was 59.4 (13.2) years, disease duration was 14.1 (11.5) years, and 83% of patients were women. The baseline mean (SD) HAQ-DI score was 0.84 (0.75). The baseline fatigue VAS score was 4.2 (2.9) and at follow up was 4.3 (2.8) (mean change of −0.07 [2.5], p=NS). The fatigue change score (0–10 scale) for somewhat better and somewhat worsened for fatigue anchor averaged −1.12 and 1.26, respectively. Using pain anchor, the fatigue changed score for somewhat better and somewhat worsened averaged −0.87 and 1.13 and using global anchor, the fatigue changed score for somewhat better and somewhat worsened averaged −0.82 and 1.17, respectively. Effect size (ES) estimates using 3 anchors were small for somewhat better (range: 0.27 to 0.39) and somewhat worsened (range: 0.40 to 0.44) groups but larger than the no-change group (range: 0.03 to 0.08). Conclusions The MID for fatigue VAS is between −0.82 to −1.12 for improvement and 1.13 to 1.26 for worsening on 0–10 scale in a large RA clinical practice and similar to that seen in RA clinical trials. This information can aid in

  5. Inbreeding avoidance, patch isolation and matrix permeability influence dispersal and settlement choices by male agile antechinus in a fragmented landscape.

    2014-03-01

    Animal dispersal is highly non-random and has important implications for the dynamics of populations in fragmented habitat. We identified interpatch dispersal events from genetic tagging, parentage analyses and assignment tests and modelled the factors associated with apparent emigration and post-dispersal settlement choices by individual male agile antechinus (Antechinus agilis, a marsupial carnivore of south-east Australian forests). Emigration decisions were best modelled with on data patch isolation and inbreeding risk. The choice of dispersal destination by males was influenced by inbreeding risk, female abundance, patch size, patch quality and matrix permeability (variation in land cover). Males were less likely to settle in patches without highly unrelated females. Our findings highlight the importance of individual-level dispersal data for understanding how multiple processes drive non-randomness in dispersal in modified landscapes. Fragmented landscapes present novel environmental, demographic and genetic contexts in which dispersal decisions are made, so the major factors affecting dispersal decisions in fragmented habitat may differ considerably from unfragmented landscapes. We show that the spatial scale of genetic neighbourhoods can be large in fragmented habitat, such that dispersing males can potentially settle in the presence of genetically similar females after moving considerable distances, thereby necessitating both a choice to emigrate and a choice of where to settle to avoid inbreeding. © 2013 The Authors.

  6. Variation in parent–offspring kinship in socially monogamous systems with extra‐pair reproduction and inbreeding

    Female extra‐pair reproduction in socially monogamous systems is predicted to cause cuckolded socially‐paired males to conditionally reduce paternal care, causing selection against extra‐pair reproduction and underlying polyandry. However, existing models and empirical studies have not explicitly considered that cuckolded males might be related to their socially‐paired female and/or to her extra‐pair mate, and therefore be related to extra‐pair offspring that they did not sire but could rear. Selection against paternal care, and hence against extra‐pair reproduction, might then be weakened. We derive metrics that quantify allele‐sharing between within‐pair and extra‐pair offspring and their mother and her socially‐paired male in terms of coefficients of kinship and inbreeding. We use song sparrow (Melospiza melodia) paternity and pedigree data to quantify these metrics, and thereby quantify the joint effects of extra‐pair reproduction and inbreeding on a brood's total allelic value to its socially‐paired parents. Cuckolded male song sparrows were almost always detectably related to extra‐pair offspring they reared. Consequently, although brood allelic value decreased substantially following female extra‐pair reproduction, this decrease was reduced by within‐pair and extra‐pair reproduction among relatives. Such complex variation in kinship within nuclear families should be incorporated into models considering coevolutionary dynamics of extra‐pair reproduction, parental care, and inbreeding.

  8. Multiple Convergent Origins of Workerlessness and Inbreeding in the Socially Parasitic Ant Genus Myrmoxenus.

    The socially parasitic ant genus Myrmoxenus varies strongly in fundamental life history traits, such as queen-worker ratio, the timing of sexual production, and mating behavior. Myrmoxenus queens generally take over nests of Temnothorax ants, kill the resident queen by throttling, and force the workers to take care of the social parasite's brood. Young queens of M. ravouxi and other species produce large numbers of workers, which during "slave-raids" pillage host pupae from neighboring Temnothorax colonies to increase the workforce in their own nests. Other species, such as M. corsicus, have lost caste polyphenism and rear only male and female sexual offspring. Using sequences of the genes CO I/CO II and wingless we reconstruct the phylogeny of Myrmoxenus and document that the worker caste was lost convergently at least three times. Furthermore, mating in the nest and inbreeding obviously also evolved in parallel from ancestors whose sexuals presumably mated during nuptial flights. Myrmoxenus might thus provide a suitable model to investigate caste differentiation and the plasticity of mating behavior in Hymenoptera.

    A homozygous self-compatible almond, originated from self-fertilization of a self-compatible genotype and producing a reasonable yield following open pollination, exhibited a very high fruit drop rate when self-pollinated. To investigate whether fruit dropping in this individual is related to an abnormal development of the embryo sac following self-fertilization, histological sections of ovaries from self and cross-pollinated flowers were observed by light microscopy. Additionally, the presence of pollen tubes in the ovary and fruit set were determined for both types of pollination. Despite pollen tubes reached the ovary after both pollinations, differences in embryo sac and endosperm development after fertilization were found. Thus, while for cross-fertilized ovules a pro-embryo and an endosperm with abundant nuclei were generally observed, most self-fertilized ovules remained in a previous developmental stage in which the embryo sac was not elongated and endosperm nuclei were absent. Although 30 days after pollination fruit set was similar for both pollination types, at 60 days it was significantly reduced for self-pollination. These results provide evidence that the high fruit drop in this genotype is the consequence of a disrupted development of the endosperm, what could be an expression of its high level of inbreeding.

    The purpose of this study is to evaluate the performance of a natural language processing (NLP) system in classifying a database of free-text knee MRI reports at two separate academic radiology practices. An NLP system that uses terms and patterns in manually classified narrative knee MRI reports was constructed. The NLP system was trained and tested on expert-classified knee MRI reports from two major health care organizations. Radiology reports were modeled in the training set as vectors, and a support vector machine framework was used to train the classifier. A separate test set from each organization was used to evaluate the performance of the system. We evaluated the performance of the system both within and across organizations. Standard evaluation metrics, such as accuracy, precision, recall, and F1 score (i.e., the weighted average of the precision and recall), and their respective 95% CIs were used to measure the efficacy of our classification system. The accuracy for radiology reports that belonged to the model's clinically significant concept classes after training data from the same institution was good, yielding an F1 score greater than 90% (95% CI, 84.6-97.3%). Performance of the classifier on cross-institutional application without institution-specific training data yielded F1 scores of 77.6% (95% CI, 69.5-85.7%) and 90.2% (95% CI, 84.5-95.9%) at the two organizations studied. The results show excellent accuracy by the NLP machine learning classifier in classifying free-text knee MRI reports, supporting the institution-independent reproducibility of knee MRI report classification. Furthermore, the machine learning classifier performed well on free-text knee MRI reports from another institution. These data support the feasibility of multiinstitutional classification of radiologic imaging text reports with a single machine learning classifier without requiring institution-specific training data.

    Professionalism is now recognized as a core competency for graduate medical education and maintenance of certification. However, few models exist in plastic surgery that define, teach, and assess professionalism as a competency. The purpose of this project was to evaluate the effectiveness of a professionalism curriculum in an academic plastic surgery practice. We created and conducted a 6-wk, 12-h course for health care professionals in plastic surgery (faculty, residents, nurses, medical students). Teaching methods included didactic lectures, journal club, small group discussions, and book review. Topics included: (1) Professionalism in Our Culture, (2) Leadership Styles, (3) Modeling Professional Behavior, (4) Leading Your Team, (5) Managing Oneself, and (6) Leading While You Work. Using Kirkpatrick methodology to assess perception of the course (level 1 data), learning of the material (level 2 data), effect on behavior (level 3 data), and impact on the organization (level 4 data), we compiled participant questionnaires, scores from pre- and post-tests, and such metrics as incidence of sentinel events (defined as infractions requiring involvement by senior administrators), number of patient complaints reported to Patient Relations, and patient satisfaction (Press Ganey surveys), for the 6 mo before and after the course. Thirty health care professionals participated in a 6-wk course, designed to improve professionalism in plastic surgery. Level 1 data: Although only 56.5% of respondents felt that the course was a "good use of my time," 73.9% agreed that the course "will help me become a better professional" and 82.6% "would recommend the course to others." Level 2 data: Post-test scores increased from 48% to 70% (P teaching, and influencing professionalism in plastic surgery are very valuable and should be pursued by educators to help satisfy Graduate Medical Education/Maintenance of Certification requirements and to improve the performance of the organization

    Full Text Available In this study, the concept ‘academic freedom’ is discussed, its implications and value for the academics, institutions of higher education, and the society are focused, and a few suggestions for the Turkish higher education are made. Academic freedom is defined as the freedom of the academic staff to look for and to find the truth in their scientific field, to publish the findings, and to teach these findings to their students without any external intervention. The concept has gained a further definition with inclusion of research activities into academic freedom as part of the reform attempts started in the German higher education in the 19th century. Therefore, academic freedom is at the very core of the missions of the institutions of higher education; that is, teaching-learning and research. On the point of academic staff and their academic activities of the academic freedom, the subjects such as the aim of the course, choosing the teaching materials and textbooks, the lecturer, and the criteria for the measurement and evaluation of the course take place. And he point of research covers the aim of the study, academicians can’t be imposed the involve in an academic and artistic studies that conflict their values and beliefs; researchers should comply with codes of ethical principles and practices during the process of researching; and research outputs should be reported accurately and honestly without any misleading manipulation. Academic freedom does not provide any exemption from accountability in academic activities of the faculty, nor does it provide any right to act against the well-being of the society, current laws and regulations, and codes of ethical principles and practices.

    Full Text Available Academic Marketing is an investment in a future dominated by The Forth Industrial Revolution and Globalization and not an expense. This aspect will basically alter our way to teach and to learn. In its dimensions, arguably changes will be like anything we has seen before. We try to assess how will be all unfold but, anyway, academic field response at this challenge should be integrated and comprehensive, involving all stakeholders both public and private sectors, because these changes herald upheaval of whole organizations. The educational service is a special one, delivered today but with effects in the future, the future of the individual, the future of generation, the future of nations. The educational service policy adapted to the requirements of time, brings to the front the opportunity of academic marketing. To analyze demand in a professional way, to measure trends and correlated university programs with the forecast demand for jobs, it is the subject. In the case of academic education, we are talking also about cost, distribution and promotion policies, but being a special service we also discuss about ethic boundaries. This work is an open chapter focusing studies on academic megamarketing, the work keeping up with the pace of change, students enrolment mobility, overtakes job market, and an imposed win-win-win formula, applied for students, local community and academic field.

  1. Inbreeding and building up small populations of stingless bees (Hymenoptera, Apidae

    2002-12-01

    Full Text Available A study of the viability of small populations of Hymenoptera is a matter of importance to gain a better zoological, ethological, genetical and ecological knowledge of these insects, and for conservation purposes, mainly because of the consequences to the survival of colonies of many species of bees, wasps, and ants. Based on the Whiting (1943 principle, Kerr & Vencovski (1982 presented a hypothesis that states that viable populations of stingless bees (Meliponini should have at least 40 colonies to survive. This number was later extended to 44 colonies by Kerr (1985. This would be necessary to avoid any substantial amount of homozygosis in the pair of chromosomic sexual loci, by keeping at least six different sexual gene alleles in a reproductive population. In most cases this would prevent the production of useless diploid males. However, several facts weigh against considering this as a general rule. From 1990 to 2001, 287 colony divisions were made, starting with 28 foundation colonies, in the inbreeding and population experiments with the Meliponini reported here. These experiments constitute the most extensive and longest scientific research ever made with Meliponini bees. In ten different experiments presented here, seven species (one with two subspecies of Meliponini bees were inbred in five localities inside their wide-reaching native habitats, and in two localities far away from these habitats. This was done for several years. On the whole, the number of colonies increased and the loss of colonies over the years was small. In two of these experiments, although these populations were far (1,000 km and 1,200 km from their native habitat, their foundation colonies were multiplied successfuly. It was possible to build up seven strong and three expanding medium populations, starting with one, two, three or even five colonies. However, in six other cases examined here, the Whiting (1943 principle and the hypothesis of Kerr & Vencovski (1982

    Correct annotation of the genetic relationships between samples is essential for population genomic studies, which could be biased by errors or omissions. To this end, we used identity-by-state (IBS) and identity-by-descent (IBD) methods to assess genetic relatedness of individuals within HapMap phase III data. We analyzed data from 1,397 individuals across 11 ethnic populations. Our results support previous studies (Pemberton et al., 2010; Kyriazopoulou-Panagiotopoulou et al., 2011) assessing unknown relatedness present within this population. Additionally, we present evidence for 1,657 novel pairwise relationships across 9 populations. Surprisingly, significant Cotterman's coefficients of relatedness K1 (IBD1) values were detected between pairs of known parents. Furthermore, significant K2 (IBD2) values were detected in 32 previously annotated parent-child relationships. Consistent with a hypothesis of inbreeding, regions of homozygosity (ROH) were identified in the offspring of related parents, of which a subset overlapped those reported in previous studies (Gibson et al. 2010; Johnson et al. 2011). In total, we inferred 28 inbred individuals with ROH that overlapped areas of relatedness between the parents and/or IBD2 sharing at a different genomic locus between a child and a parent. Finally, 8 previously annotated parent-child relationships had unexpected K0 (IBD0) values (resulting from a chromosomal abnormality or genotype error), and 10 previously annotated second-degree relationships along with 38 other novel pairwise relationships had unexpected IBD2 (indicating two separate paths of recent ancestry). These newly described types of relatedness may impact the outcome of previous studies and should inform the design of future studies relying on the HapMap Phase III resource. PMID:23185369

    2007-01-01

    Full Text Available A frequently addressed question in conservation biology is what is the chance of survival for a population for a given number of years under certain conditions of habitat loss and human activities. This can be estimated through an integrated analysis of genetic, demographic and landscape processes, which allows the prediction of more realistic and precise models of population persistence. In this study, we modeled extinction in stochastic environments under inbreeding depression for two canid species, the maned wolf (Chrysocyon brachiurus and the crab-eating fox (Cerdocyon thous, in southwest Goiás State. Genetic parameters were obtained from six microsattelite loci (Short Tandem Repeats - STR, which allowed estimates of inbreeding levels and of the effective population size under a stepwise mutation model based on heterozygosis. The simulations included twelve alternative scenarios with varying rates of habitat loss, magnitude of population fluctuation and initial inbreeding levels. ANOVA analyses of the simulation results showed that times to extinction were better explained by demographic parameters. Times to extinction ranged from 352 to 844, in the worst and best scenario, respectively, for the large-bodied maned wolf. For the small-bodied crab-eating fox, these same estimates were 422 and 974 years. Simulations results are within the expectation based on knowledge about species' life history, genetics and demography. They suggest that populations can persist through a reasonable time (i.e., more than 200 years even under the worst demographic scenario. Our analyses are a starting point for a more focused evaluation of persistence in these populations. Our results can be used in future research aiming at obtaining better estimates of parameters that may, in turn, be used to achieve more appropriate and realist population viability models at a regional scale.

    Full Text Available An assessment of reproductive behavior and inbreeding depression, if any, in critically endangered Eremostachys superba Royle ex Benth. (Labiatae was made to unveil the factors playing vital role in it’s reproductive biology and which may be responsible for the loss of fitness, viability and vigor of the species. Breeding experiments portrayed a failure of self-fertilization and a strong tendency towards out-breeding as seed set by xenogamy was highest (44.4%. However, the narrow restricted population of the type locality in Dehra Dun Siwaliks was just a ramet population sustained by clonal propagation of rhizomatous root stock, hence any out-crossing within these homozygous individuals also amounted to inbreeding. Further, there is no other population available within the range of normal seed dispersal mechanism or insect-pollinator-flight-range. The other populations reported are only from geographically distant region of Jammu and Kashmir state of India, which is too far a distance to be covered by the Nomia rustica West. and Ceratina heiroglyphica Sm., the oligophilic pollinators of E. superba, hence any crossing taking place also amounts to selfing in strict sense. Chances of induction of genetic variation by crossing between two different populations are remote. This was also supported by the data of seed production and germination experiments. Even the healthy seeds suffered from loss of fitness and failed to germinate under natural conditions. This strongly indicated prevalence of inbreeding depression and loss of fitness of the progeny right from the stage of germination, a phenomenon hazardous for sustenance and perpetuation of species leading to rarity.

    Populations with limited ranges can be highly vulnerable to changes in their environment and are, thus, of high conservation concern. Populations that experience human-induced range reductions are often highly inbred and lack genetic diversity, but it is unknown whether this is also the case for populations with naturally small ranges. The fishes Poecilia sulphuraria (listed as critically endangered) and Poecilia thermalis, which are endemic to small hydrogen sulphide-rich springs in southern Mexico, are examples of such populations with inherently small habitats. We used geometric morphometrics and population genetics to quantify phenotypic and genetic variation within and among two populations of P. sulphuraria and one population of P. thermalis. Principal component analyses revealed phenotypic and genetic differences among the populations. Evidence for inbreeding was low compared to populations that have undergone habitat reduction. The genetic data were also used to infer the demographic history of these populations to obtain estimates for effective population sizes and migration rates. Effective population sizes were large given the small habitats of these populations. Our results imply that these three endemic extremophile populations should each be considered separately for conservation purposes. Additionally, this study suggests that populations in naturally small habitats may have lower rates of inbreeding and higher genetic diversity than expected, and therefore may be better equipped to handle environmental perturbations than anticipated. We caution, however, that the inferred lack of inbreeding and the large effective population sizes could potentially be a result of colonization by genetically diverse ancestors. © 2017 John Wiley & Sons Ltd.

  7. Evidence of high inbreeding in a population of the endangered giant anteater, Myrmecophaga tridactyla (Myrmecophagidae, from Emas National Park, Brazil

    Full Text Available We report the genetic structure, relatedness and mating structure of a population of the endangered giant anteater Myrmecophaga tridactyla Linnaeus, 1758 in the Emas National Park, Brazil, based on variability at five microsatellite loci. Additionally, we addressed the hypothesis that the M. tridactyla population studied has low levels of polymorphism and high levels of inbreeding and relatedness and that animals with overlapping home range are highly related. All five microsatellite loci displayed low levels of polymorphism and of expected and observed heterozygosity. The low level of polymorphism and high inbreeding showed by the population studied may be the outcome of high mortality and reduction in population size due to recurrent fire events in the Emas National Park, as reported in 1994. The reduction in population size may have led to a higher frequency of mating between closely related animals, augmented by the isolation of the population in the park because of the expansion of agricultural land and fragmentation of the Cerrado environment. The natural history of M. tridactyla and the phylopatric (sex-biased dispersal behavior of females should increase the effects of isolation and bottlenecking, decreasing gene flow and increasing inbreeding. However, the low levels of polymorphism found in this population may simply be due to the natural history and evolution of M. tridactyla as reported for other species. The genetic structure and dynamics of this population needs to be investigated more profoundly in order to provide sound data for the design of conservation strategies for M. tridactyla in the Emas National Park.

  9. Are Australasian academic physicians an endangered species?

    Wilson, A

    2007-11-01

    It has been stated that academic medicine is in a worldwide crisis. Is this decline in hospital academic practice a predictable consequence of modern clinical practice with its emphasis on community and outpatient-based services as well as a corporate health-care ethos or does it relate to innate problems in the training process and career structure for academic clinicians? A better understanding of the barriers to involvement in academic practice, including the effect of gender, the role and effect of overseas training, expectation of further research degrees and issues pertaining to the Australian academic workplace will facilitate recruitment and retention of the next generation of academic clinicians. Physician-scientists remain highly relevant as medical practice and education evolves in the 21st century. Hospital-based academics carry out a critical role in the ongoing mentoring of trainees and junior colleagues, whose training is still largely hospital based in most specialty programmes. Academic clinicians are uniquely placed to translate the rapid advances in medical biology into the clinical sphere, by guiding and carrying out translational research as well as leading clinical studies. Academic physicians also play key leadership in relations with government and industry, in professional groups and medical colleges. Thus, there is a strong case to assess the problems facing recruitment and retention of physician-scientists in academic practice and to develop workable solutions.

    The primary goal of captive breeding programmes for endangered species is to prevent extinction, a component of which includes the preservation of genetic diversity and avoidance of inbreeding. This is typically accomplished by minimizing mean kinship in the population, thereby maintaining equal representation of the genetic founders used to initiate the captive population. If errors in the pedigree do exist, such an approach becomes less effective for minimizing inbreeding depression. In this study, both pedigree- and DNA-based methods were used to assess whether inbreeding depression existed in the captive population of the critically endangered Attwater's Prairie-chicken (Tympanuchus cupido attwateri), a subspecies of prairie grouse that has experienced a significant decline in abundance and concurrent reduction in neutral genetic diversity. When examining the captive population for signs of inbreeding, variation in pedigree-based inbreeding coefficients (f(pedigree)) was less than that obtained from DNA-based methods (f(DNA)). Mortality of chicks and adults in captivity were also positively correlated with parental relatedness (r(DNA)) and f(DNA), respectively, while no correlation was observed with pedigree-based measures when controlling for additional variables such as age, breeding facility, gender and captive/release status. Further, individual homozygosity by loci (HL) and parental rDNA values were positively correlated with adult mortality in captivity and the occurrence of a lethal congenital defect in chicks, respectively, suggesting that inbreeding may be a contributing factor increasing the frequency of this condition among Attwater's Prairie-chickens. This study highlights the importance of using DNA-based methods to better inform management decisions when pedigrees are incomplete or errors may exist due to uncertainty in pairings. © 2013 John Wiley & Sons Ltd.

    Este artículo sugiere que esta época es la mejor y peor para la labor académica. La mejor en cuanto hay más publicaciones académicas que nunca. Y la peor porque sobra mucho de estas publicaciones. Trabajando en las condiciones competitivas del capitalismo académico, los académicos se sienten en la necesidad de continuar publicando, independientemente de que tengan algo que decir. Las presiones de publicar continuamente y promover la propia perspectiva se reflejan en la manera en la que los científicos sociales están escribiendo. Y es que los académicos utilizan un lenguaje técnico basado en sustantivos, con una precisión menor a la del lenguaje ordinario. Los estudiantes de postgrado han sido educados en esta manera de escribir como una condición previa a iniciarse en las ciencias sociales. Así, la naturaleza misma del capitalismo académico no sólo determina las condiciones en las que los académicos trabajan, sino que también afecta su manera de escribir.


    This paper suggests that it is the best and worst of times for academic work. It is the best of times because there are more academics publishing than ever before. It is the worst of times because there is much unnecessary publication. Working in the competitive conditions of academic capitalism, academics feel impelled to keep publishing, whether or not they have anything to say. The pressures to publish continually and to promote one’s own approach are reflected in the way that social scientists are writing. Academics use a noun-based technical language, which is less precise than ordinary language. Postgraduates are taught this way of writing as a precondition for entering the social sciences. In this way, the nature of academic capitalism not only determines the conditions under which academics are working but it affects the way that they are writing.

  19. Sex linked versus autosomal inbreeding coefficient in close consanguineous marriages in the Basque country and Castile (Spain): genetic implications.

    1995-10-01

    Pedigree structures of 161 uncle/niece-aunt/nephew and 4420 first cousin consanguineous marriages registered during the 19th and 20th centuries in two large and very different Spanish regions have been analysed and their genetic consequences evaluated. The frequencies of the different pedigree subtypes within each degree of relationship were quite similar in both populations despite significant heterogeneity in inbreeding patterns. The mean X-linked inbreeding coefficient (Fx) for each type of cousin mating was calculated and compared to that expected for autosomal genes (F). The effect of genealogical structure on the Fx/F ratio was compared to different cultural populations worldwide. Preferentiality and avoidance of close consanguinity along with specific types of pedigrees are discussed on the basis of premarital migration and sociocultural rules still deeply rooted in certain human groups. By admitting that the observed Fx coefficient is usually higher than F in most human populations some remarks have been made in terms of population genetic risk.

    Selective logging may impact patterns of genetic diversity within populations of harvested forest tree species by increasing distances separating conspecific trees, and modifying physical and biotic features of the forest habitat. We measured levels of gene diversity, inbreeding, pollen dispersal and spatial genetic structure (SGS) of an Amazonian insect-pollinated Carapa guianensis population before and after commercial selective logging. Similar levels of gene diversity and allelic richness were found before and after logging in both the adult and the seed generations. Pre- and post-harvest outcrossing rates were high, and not significantly different from one another. We found no significant levels of biparental inbreeding either before or after logging. Low levels of pollen pool differentiation were found, and the pre- vs. post-harvest difference was not significant. Pollen dispersal distance estimates averaged between 75 m and 265 m before logging, and between 76 m and 268 m after logging, depending on the value of tree density and the dispersal model used. There were weak and similar levels of differentiation of allele frequencies in the adults and in the pollen pool, before and after logging occurred, as well as weak and similar pre- and post-harvest levels of SGS among adult trees. The large neighbourhood sizes estimated suggest high historical levels of gene flow. Overall our results indicate that there is no clear short-term genetic impact of selective logging on this population of C. guianensis.

    Full Text Available The ability to cite sources appropriately is an important feature of academic writing. Academic writers are expected to integrate ideas of others into their texts and take a stance towards the reported material as they develop their arguments. Despite this importance, research has shown that citation presents considerable difficulties for students, particularly non-native English speakers. Such difficulties include using citations effectively in writing and understanding them in reading, expressing one’s voice and signalling citations in writing so that there is a clear distinction between one’s ideas and those derived from source materials. This study investigates the types of reporting verbs used by students to refer to the work of others and the extent to which they evaluate the work of others in their writing. It draws from a corpus of approximately 80 000 words from essays written by students in two departments at the University of Botswana (Botswana. The findings show that students used more informing verbs, associated with the neutral passing of information from the source to the reader, without interpreting the information cited, compared with argumentative verbs (which signify an evaluative role. The results of the study underscore the importance of teaching reporting verbs in the English for academic purposes classroom and making students aware of their evaluative potential.

    Full Text Available Objective – To survey the current status of Web usability Policies/Standards/Guidelines (PSGs found in academic libraries of the Association of Research Libraries (ARL. Researchers sought to investigate whether PSGs are in place, the levels of difficulty surrounding implementation, the impact of PSGs on design, testing, and resource allocation, and the relationship between ARL ranking and usability practice or PSGs.Design – Survey.Setting – North America.Subjects – Academic libraries of the ARL.Methods – An 18‐question survey consisting of multiple choice, Likert scale, and open‐ended questions was sent to all 113 ARL libraries in November 2007. Survey recipients were selected as the person in charge of Web site usability by visiting library Web sites and phone inquiry. The survey was concluded in January 2008 with a response rate of 74% (84 institutions. The researchers used t‐test to detect any difference in ARL library ranking between libraries with and without PSGs. Pair‐wise t‐tests were conducted to identify gaps in difficulty implementing PSGs. In addition, they used Pearson’s Correlation to investigate any significant correlations between variables such as ARL rank and resource allocation.Main Results – Of the 84 respondents, 34 (40% have general library Web PSGs and 25 (30% have specific usability PSGs; 41 (49% have at least one type of in‐library PSG. Of the 43 (51% libraries that do not have PSGs, 30 (36% are at universities with institutional Web usability PSGs; 26 (87% follow those guidelines. There was no statistically significant relationship between ARL ranking and PSG status (see Table 1. The authors asked about difficulty in implementing PSGs. Of the 32 libraries responding to a question about general library Web PSGs, most had slight or moderate difficulty. Twenty‐three libraries with specific usability PSGs identified difficulty levels; some had no difficulty, but a majority had moderate difficulty

    We reasoned that mating animals by minimising the covariance between ancestral contributions (MCAC mating) will generate less inbreeding and at least as much genetic gain as minimum-coancestry mating in breeding schemes where the animals are truncation-selected. We tested this hypothesis by stoch...

    The aim of our study was to understand the relationship between consanguineous marriages and reproductive outcomes. A total of 999 families were recruited from five Muslim populations of Jammu region. Family pedigrees were drawn to access the family history and inbreeding status in terms of coefficient of inbreeding (F). Fertility, mortality, secondary sex ratio, selection intensity, and lethal equivalents were measured using standard methods. The significant differences for gross fertility was found to be higher among inbred groups as compared to the unrelated families (P consanguineous families of all populations in comparison with the non-consanguineous family groups. Moreover, the prenatal and postnatal child mortality rates (i.e., U5MR and U18MR) have presented a persuasive increase with an upsurge in the homozygosity level. The mortality rate was found to be maximum among families with the highest value of coefficient of inbreeding (F). The selection intensity (SI) also showed inflations among families with respect to their increasing inbreeding coefficients. The greater values of lethal equivalents per gamete (LEs/gamete) were observed for autosomal inheritance in comparison with sex-linked inheritance. Our conclusive assessment brings out the deleterious consequence of consanguineous marriages on reproductive outcomes.

    Adverse conditions may be the norm rather than the exception in natural populations. Many populations experience poor nutrition on a seasonal basis. Further, brief interludes of inbreeding can be common as population density fluctuates and because of habitat fragmentation. Here, we investigated the effects of poor nutrition and inbreeding on traits that can be very important to reproductive success and fitness in males: testes mass, sperm concentration, and sperm viability. Our study species was Narnia femorata, a species introduced to north-central Florida in the 1950s. This species encounters regular, seasonal changes in diet that can have profound phenotypic effects on morphology and behavior. We generated inbred and outbred individuals through a single generation of full-sibling mating or outcrossing, respectively. All juveniles were provided a natural, high-quality diet of Opuntia humifusa cactus cladode with fruit until they reached adulthood. New adult males were put on a high- or low-quality diet for at least 21 days before measurements were taken. As expected, the low-quality diet led to significantly decreased testes mass in both inbred and outbred males, although there were surprisingly no detectable effects on sperm traits. We did not find evidence that inbreeding affected testes mass, sperm concentration, and sperm viability. Our results highlight the immediate and overwhelming effects of nutrition on testes mass, while suggesting that a single generation of inbreeding might not be detrimental for primary sexual traits in this particular population.

    For the past 2 decades, the Spooner Agriculture Research Station (ARS) of the University of Wisconsin-Madison operated the only dairy sheep research flock in North America. The objectives of the present study were to 1) obtain estimates of genetic parameters for lactation and reproductive traits in dairy ewes, 2) estimate the amount of genetic change in these traits over time, and 3) quantify the level of inbreeding in this flock over the last 20 yr. Multiple-trait repeatability models (MTRM) were used to analyze ewe traits through their first 6 parities. The first MTRM jointly analyzed milk (180-d-adjusted milk yield [180d MY]), fat (180-d-adjusted fat yield [180d FY]), and protein (180-d-adjusted protein yield [180d PY]) yields adjusted to 180 d of lactation; number of lambs born per ewe lambing (NLB); and lactation average test-day somatic cell score (LSCS). A second MTRM analyzed 180d MY, NLB, LSCS, and percentage milk fat (%F) and percentage milk protein (%P). The 3 yield traits were moderately heritable (0.26 to 0.32) and strongly genetically correlated (0.91 to 0.96). Percentage milk fat and %P were highly heritable (0.53 and 0.61, respectively) and moderately genetically correlated (0.61). Milk yield adjusted to 180 d was negatively genetically correlated with %F and %P (-0.31 and -0.34, respectively). Ewe prolificacy was not significantly ( > 0.67) genetically correlated with yield traits, %P, or LSCS but lowly negatively correlated with %F (-0.26). Lactation somatic cell score was unfavorably genetically correlated with yield traits (0.28 to 0.39) but not significantly ( > 0.09) correlated with %F, %P, and NLB. Within-trait multiple-trait models through the first 4 parities revealed that 180d MY, 180d FY, 180d PY, %F, and %P were strongly genetically correlated across parity (0.67 to 1.00). However, the genetic correlations across parity for NLB and LSCS were somewhat lower (0.51 to 0.96). Regressing predicted breeding values for 180d MY, without and with

    Full Text Available The most common benchmarks for faculty productivity are derived from Medical Group Management Association (MGMA or Vizient-AAMC Faculty Practice Solutions Center ® (FPSC databases. The Association of Pathology Chairs has also collected similar survey data for several years. We examined the Association of Pathology Chairs annual faculty productivity data and compared it with MGMA and FPSC data to understand the value, inherent flaws, and limitations of benchmarking data. We hypothesized that the variability in calculated faculty productivity is due to the type of practice model and clinical effort allocation. Data from the Association of Pathology Chairs survey on 629 surgical pathologists and/or anatomic pathologists from 51 programs were analyzed. From review of service assignments, we were able to assign each pathologist to a specific practice model: general anatomic pathologists/surgical pathologists, 1 or more subspecialties, or a hybrid of the 2 models. There were statistically significant differences among academic ranks and practice types. When we analyzed our data using each organization’s methods, the median results for the anatomic pathologists/surgical pathologists general practice model compared to MGMA and FPSC results for anatomic and/or surgical pathology were quite close. Both MGMA and FPSC data exclude a significant proportion of academic pathologists with clinical duties. We used the more inclusive FPSC definition of clinical “full-time faculty” (0.60 clinical full-time equivalent and above. The correlation between clinical full-time equivalent effort allocation, annual days on service, and annual work relative value unit productivity was poor. This study demonstrates that effort allocations are variable across academic departments of pathology and do not correlate well with either work relative value unit effort or reported days on service. Although the Association of Pathology Chairs–reported median work relative

    To portray the professional experiences of men and women in academic general surgery with specific attention to factors associated with differing academic productivity and with leaving academia. A 131-question survey was mailed to all female (1,076) and a random 2:1 sample of male (2,152) members of the American College of Surgeons in three mailings between September 1998 and March 1999. Detailed questions regarding academic rank, career aspirations, publication rate, grant funding, workload, harassment, income, marriage and parenthood were asked. A five-point Likert scale measured influences on career satisfaction. Responses from strictly academic and tenure-track surgeons were analyzed and interpreted by gender, age, and rank. Overall, 317 surgeons in academic practice (168 men, 149 women) responded, of which 150 were in tenure-track positions (86 men, 64 women). Men and women differed in academic rank, tenure status, career aspirations, and income. Women surgeons had published a median of ten articles compared with 25 articles for men (p career satisfaction was high, but women reported feeling career advancement opportunities were not equally available to them as to their male colleagues and feeling isolation from surgical peers. Ten percent to 20% of surgeons considered leaving academia, with women assistant professors (29%) contemplating this most commonly. Addressing the differences between men and women academic general surgeons is critical in fostering career development and in recruiting competitive candidates of both sexes to general surgery.

    Personality–performance research typically uses samples of psychology students without questioning their representativeness. The present article reports two studies challenging this practice. Study 1: group differences in the Big Five personality traits were explored between students (N = 1067......) in different academic majors (medicine, psychology, law, economics, political science, science, and arts/humanities), who were tested immediately after university enrolment. Study 2: six and a half years later the students’ academic records were obtained, and predictive validity of the Big Five personality...... traits and their subordinate facets was examined in the various academic majors in relation to Grade Point Average (GPA). Significant group differences in all Big Five personality traits were found between students in different academic majors. Also, variability in predictive validity of the Big Five...

    Habitat fragmentation is extensive throughout the world, converting natural ecosystems into fragments of varying size, density and connectivity. The potential value of remnant trees in agricultural landscapes as seed sources and in connecting fragments has formed a fertile area of debate. This study contrasted the mating patterns of bat-pollinated Pachira quinata trees in a continuous forest to those in pasture through microsatellite-based paternity analysis of progeny. The breeding system was determined by analysis of pollen tube growth and seed production from controlled pollinations. Fitness of selfed and outcrossed seed was compared by germination and seedling growth. There was more inbreeding within pasture trees (outcrossing=0.828±0.015) compared with forest trees (0.926±0.005). Pasture trees had fewer sires contributing to mating events, but pollen dispersal distances were greater than those in the forest. Paternity analysis showed variation in outcrossing rates among pasture trees with high proportions of external and self pollen sources detected. A leaky self-incompatibility system was found, with self pollen having reduced germination on stigmas and slower growth rate through the style. Controlled pollinations also showed a varied ability to self among trees, which was reflected in the selfing rates among pasture trees shown by the paternity analysis (0-80% selfing). Self pollination resulted in lower seed set, germination and seedling growth compared with outcrossing. While remnant trees in agricultural landscapes are involved in broader mating patterns, they show increased but varied levels of inbreeding, which result in reduced fitness.

    Purpose: To build a world-class medical physics educational program that capitalizes on expertise distributed over several clinical, government, and academic centres. Few if any of these centres would have the critical mass to solely resource a program. Methods: In order to enable an academic program, stakeholders from five institutions made a proposal to Carleton University for a) a research network with defined membership requirements and a process for accepting new members, and b) a graduate specialization (MSc and PhD) in medical physics. Both proposals were accepted and the program has grown steadily. Our courses are taught by medical physicists from across the collaboration. Our students have access to physicists in: clinical radiotherapy (the Ottawa Cancer Centre treats 4500 new patients/y), radiology, cardiology and nuclear medicine, Canada’s primary standards dosimetry laboratory, radiobiology, and university-based medical physics research. Our graduate courses emphasize the foundational physics plus applied aspects of imaging, radiotherapy, and radiobiology. Active researchers in the city-wide volunteer-run network are appointed as adjunct professors by Physics, giving them access to national funding competitions and partial student funding through teaching assistantships while opening up facilities in their institutions for student thesis research. Results: The medical physics network has grown to ∼40 members from eight institutions and includes five full-time faculty in Physics and 17 adjunct research professors. The graduate student population is ∼20. Our graduates have proceeded to a spectrum of careers. Our alumni list includes a CCPM Past-President, the current COMP President, many clinical physicists, and the heads of at least three major clinical medical physics departments. Our PhD was Ontario’s first CAMPEP-accredited program. Conclusion: A self-governing volunteer network is the foundational element that enables an MSc/PhD medical

    Worldwide mobility of researchers is generally correlated with an enhancement of the continuous interchange of ideas and is therefore highly stimulated. Flemish universities have occasionally been criticized for providing limited career opportunities for foreign researchers. However, presently no reliable data is available on researchers’ mobility in Flanders. For the five Flemish universities a full dataset is available at the ECOOM Centre for R&D Monitoring, containing all academic appointments and PhD’s awarded since 1990-1991. This dataset allows for prospective analyses within the Flemish university system as well as retrospective analyses and provides information on international and interuniversity recruitment and academic inbreeding. The present results confirm that the academic system in Flanders is indeed recognized by a tradition of internal recruitment. However specific differences between the universities and the scientific disciplines are observed calling for a more complex study of researchers’ mobility and of the relationship between mobility and research excellence.
