  1. Contrasting academic and lay press print coverage of the 2013-2016 Ebola Virus Disease outbreak.

    Directory of Open Access Journals (Sweden)

    Mark D Kieh

    Full Text Available Under a traditional paradigm, only those with the expected background knowledge consume academic literature. The lay press, as well as government and non-government agencies, play a complementary role of extracting findings of high interest or importance and translating them for general viewing. The need for accurate reporting and public advising is paramount when attempting to tackle epidemic outbreaks through behavior change. Yet, public trust in media outlets is at a historic low. The Crisis and Emergency Risk Communication (CERC model for media reporting on public health emergencies was established in 2005 and has subsequently been used to analyze media reporting on outbreaks of influenza and measles as well as smoking habits and medication compliance. However, no media analysis had yet been performed on the 2013-2016 Ebola Virus Disease (EVD outbreak. This study compared the EVD information relayed by lay press sources with general review articles in the academic literature through a mixed-methods analysis. These findings suggest that comprehensive review articles could not serve as a source to clarify and contextualize the uncertainties around the EVD outbreak, perhaps due to adherence to technical accuracy at the expense of clarity within the context of outbreak conditions. This finding does not imply inferiority of the academic literature, nor does it draw direct causation between confusion in review articles and public misunderstanding. Given the erosion of the barriers siloing academia, combined with the demands of today's fast-paced media environment, contemporary researchers should realize that no study is outside the public forum and to therefore consider shifting the paradigm to take personal responsibility in the process of accurately translating their scientific words into public policy actions to best serve as a source of clarity.

    The employment of professional interviewers from academic survey centers to conduct surveys has been standard practice. Because one goal of community-engaged research is to provide professional skills to community residents, this paper considers whether employing locally trained lay interviewers from within the community may be as effective as employing interviewers from an academic survey center with regard to unit and item nonresponse rates and cost. To study a nutrition-focused intervention, 1035 in-person household interviews were conducted in East Los Angeles and Boyle Heights, 503 of which were completed by lay community interviewers. A chi-square test was used to assess differences in unit nonresponse rates between professional and community interviewers and Welch's t tests were used to assess differences in item nonresponse rates. A cost comparison analysis between the two interviewer groups was also conducted. Interviewers from the academic survey center had lower unit nonresponse rates than the lay community interviewers (16.2% vs. 23.3%; p < 0.01). However, the item nonresponse rates were lower for the community interviewers than the professional interviewers (1.4% vs. 3.3%; p < 0.01). Community interviewers cost approximately $415.38 per survey whereas professional interviewers cost approximately $537.29 per survey. With a lower cost per completed survey and lower item nonresponse rates, lay community interviewers are a viable alternative to professional interviewers for fieldwork in community-based research. Additional research is needed to assess other important aspects of data quality interviewer such as interviewer effects and response error.

    The current work builds a definition of irritability from both academic definitions and lay perspectives. In Study 1, a quantitative content analysis of academic definitions resulted in eight main content categories (i.e., behaviour, emotion or affect, cognition, physiological, qualifiers, irritant, stability or endurance, and other). In Study 2, a community sample of 39 adults participated in qualitative interviews. A deductive thematic analysis resulted in two main themes. The first main theme dealt with how participants positioned irritability in relation to other negative states. The second dealt with how participants constructed irritability as both a loss of control and as an experience that should be controlled. The discussion integrates the findings of both studies and provides a concise, but comprehensive definition.

    Innovation and entrepreneurship in health care can help solve the current health care crisis by creating products and services that improve quality and convenience while reducing costs. To effectively drive innovation and entrepreneurship within the current health care delivery environment, academic institutions will need to provide education, promote networking across disciplines, align incentives, and adapt institutional cultures. This article provides a general review of entrepreneurship and commercialization from the perspective of academic radiology departments, drawing on information sources in several disciplines including radiology, medicine, law, and business. Our review will discuss the role of universities in supporting academic entrepreneurship, identify drivers of entrepreneurship, detail opportunities for academic radiologists, and outline key strategies that foster greater involvement of radiologists in entrepreneurial efforts and encourage leadership to embrace and support entrepreneurship.

    Universities, as subjects of the academic environment, are institutions with the priority of education and research. The task of the marketing concept in the academic field is to communicate with all important target groups to support a stronger position and their perception of the school. The aim of the intervention is to increase the prestige, improve awareness, support positive attitudes, and present successful results in all areas of activity. This means creation and protection of a positive image, which enables higher interest of all target groups and secures better awareness about it.

    2009-01-01

    Full Text Available Abstract This study compares laying performances between two environments of dwarf laying hen lines segregating for the naked neck mutation (NA locus, a selected dwarf line of brown-egg layers and its control line. Layers with one of the three genotypes at the NA locus were produced from 11 sires from the control line and 12 sires from the selected line. Two hatches produced 216 adult hens in Taiwan and 297 hens in France. Genetic parameters for laying traits were estimated in each environment and the ranking of sire breeding values was compared between environments. Laying performance was lower, and mortality was higher in Taiwan than in France. The line by environment interaction was highly significant for body weight at 16 weeks, clutch length and egg number, with or without Box-Cox transformation. The selected line was more sensitive to environmental change but in Taiwan it could maintain a higher egg number than the control line. Estimated heritability values in the selected line were higher in France than in Taiwan, but not for all the traits in the control line. The rank correlations between sire breeding values were low within the selected line and slightly higher in the control line. A few sire families showed a good ranking in both environments, suggesting that some families may adapt better to environmental change.

    Dental education is regarded as a complex, demanding and often stressful pedagogical procedure. Undergraduates, while enrolled in programmes of 4-6 years duration, are required to attain a unique and diverse collection of competences. Despite the major differences in educational systems, philosophies, methods and resources available worldwide, dental students' views regarding their education appear to be relatively convergent. This paper summarizes dental students' standpoint of their studies, showcases their experiences in different educational settings and discusses the characteristics of a positive academic environment. It is a consensus opinion that the 'students' perspective' should be taken into consideration in all discussions and decisions regarding dental education. Moreover, it is suggested that the set of recommendations proposed can improve students' quality of life and well-being, enhance their total educational experience and positively influence their future careers as oral health physicians. The 'ideal' academic environment may be defined as one that best prepares students for their future professional life and contributes towards their personal development, psychosomatic and social well-being. A number of diverse factors significantly influence the way students perceive and experience their education. These range from 'class size', 'leisure time' and 'assessment procedures' to 'relations with peers and faculty', 'ethical climate' and 'extra-curricular opportunities'. Research has revealed that stress symptoms, including psychological and psychosomatic manifestations, are prevalent among dental students. Apparently some stressors are inherent in dental studies. Nevertheless, suggested strategies and preventive interventions can reduce or eliminate many sources of stress and appropriate support services should be readily available. A key point for the Working Group has been the discrimination between 'teaching' and 'learning'. It is suggested that

    Laying hens are chronically exposed to high levels of ammonia (NH3), one of the most abundant aerial pollutants in poultry houses. Tests for aversion to NH3 in laying hens have used artificially sourced NH3/air mixtures (i.e., from a gas cylinder) showing that birds prefer fresh air to NH3. However, artificially sourced NH3/air mixtures may not accurately reflect barn air conditions, where manure emits a variety of gases. Herein, we investigated whether laying hens differentiate between artificially and naturally sourced NH3/air mixtures and how exposure to NH3 affects foraging and aversive behavior. A total of 20 laying hens was exposed to artificially sourced [A] (from an anhydrous NH3 cylinder) and naturally sourced [N] (from conspecific laying hen excreta) gas mixtures. Hens were exposed to A and N mixtures with NH3 concentrations of 25 and 45 ppm, as well as fresh air [FA]. During the experiment, all birds were exposed to each treatment 3 times using a custom-built polycarbonate chamber, containing a foraging area (containing raisins, mealworms, and feed mix) and a gas delivery system. All testing sessions were video recorded, analyzed with INTERACT® software, and subjected to a GLIMMIX procedure in SAS. Our results showed that the laying hens spent less time foraging overall (P hens were more likely to forage for a longer time (with fewer interruptions) in N than in A treatments (P hens also reacted with greater aversion towards treatment A compared to treatment N (P hens of our study preferred fresh to ammoniated air and that they behaved differently in artificially and naturally sourced NH3/air mixtures, possibly due to the presence of familiar stimuli from the excreta. These findings have implications for new developments in methodological approaches for behavioral testing and for recommendations regarding NH3 levels inside poultry barns. © 2017 Poultry Science Association Inc.

    This article presents a historical review, from an ethic standpoint, of the national legislation that rules the practice of Medicine in Colombia; ity also refers to the deontological code and the Colombian psychiatric code as well as to the commitment of the Health Faculty of the Universidad del Valle regarding ethical conducts. Ethics is introduced as an original innate faculty, resulting from cognitive development and learning while being also a manifestation of underlying biological processes or a result of the interaction of different models. The teaching-learning process is a situation in which teachers and students get together in order to acquire competences that are to be ethically expressed. Empirical studies have shown transgressive forms of behavior in teachers, students and academic administrators throughout the world; in addition, the mass media expose transgressions committed by other social groups such as politicians, financiers, clergymen, researchers, etc. Firstly proposed as a problem-solving strategy is the acceptance of the very existence of transgressions, followed by the conformation of a committee aimed at principle-identification for, subsequently, undertaking eductional and following-up actions, while administering sanctions when necessary. The proposal for adopting problem-solving strategies for the Faculty of Health of the Universidad del Valle is also presented. Copyright © 2012 Asociación Colombiana de Psiquiatría.

    Full Text Available Digital library is a term for a library of the present and of the future challenging the traditional libraries. Authors are interested mostly in the digital space of Slovene academic instutions. In the research, the digital collections of most of the University of Ljubljana faculties are examined. A questionnaire was used to obtain information about the users' (students' needs and their acquaintance with the concept of the digital library. Two things were expected: the research was aimed at finding the positive effect of digital libraries on studies, and the questionnaire as an incentive in the library profession for further research. The questionnaire was made in the end of 1999 at the Faculty of Arts in Ljubljana (FF. It included 275 students of FF. The results showed that the students of librarianship had a better understanding of the term digital library than the students of other courses. A personal computer is used frequently and with pleasure by most questioned students. The term digital library is known to 71,1% of the students of librarianship, and only to 43,8% of others. Most of the students chose the correct definition of the digital library (the digital library is a collection of disparate systems and resources, accessible on the net, but that was, by the authors' opinion, mostly a lucky guess. According to the findings of the research, the authors believe that future development will improve and accelerate a wider use of digital libraries, in Slovenia as well.

    Productive faculty are key to generating new knowledge and advancing pharmacy practice. The work environments of academic pharmacists are critical to their vitality, commitment, and longevity. To (1) identify correlates of faculty scholarly productivity and teaching effectiveness, considering personal and environmental characteristics; (2) determine the relationship between a faculty's perception of organizational citizenship behaviors they witness with the organizational culture of their employing college/school of pharmacy; and (3) describe the relationship between organizational climate, job satisfaction, and commitment of academic pharmacists. A self-administered survey was disseminated to a random sample of U.S. academic pharmacists acquired from AACP list-servs. The survey measured perceptions of their organization's culture, the organizational citizenship behaviors they witness at their institution, their job satisfaction, teaching load and productivity, and scholarly productivity based upon peer-reviewed scholarly papers accepted. Both bivariate and multivariate (regression) procedures were employed to identify factors most responsible for explaining academic pharmacist's work environment. Responses were received from 177 of 600 survey recipients. Faculty reported having had accepted 10.9 ± 13.6 papers in peer-reviewed journals during the previous 5 years, with most of those in journals with relatively low Impact Factor scores. Faculty productivity was related to type of academic institution employed, teaching effectiveness, job satisfaction, and other factors. Organizational citizenship behaviors and organizational culture was seen similarly by faculty of varied ranks and experience levels. Commitment to remain at the current college/school of pharmacy was highly associated with culture, climate, and job satisfaction conditions. The results provided evidence for a strong connection or nexus between teaching and research effectiveness. Organizational

  8. Evolution Trends Of The Leadership In The Romanian Academic Environment

    2013-05-01

    Full Text Available The purpose of this paper is to analyze the trends that mark the evolution of leadership in the Romanian academic environment from a systemic perspective to integrate the past, present and future. In our approach we start from an analysis of how the multiple transformations that took place within the Romanian society in its whole has influenced the academic environment, emphasizing especially the moments of rupture caused by the numerous reforms started and never completed and the problems of chronic underfunding faced by the system. Starting from the observation that globally there are many voices questioning the level of adaptation of the current educational system to the realities of the contemporary world, we shall briefly present a couple of views on how the European and the American education of the future might look and also the way in which the academic leadership should manage this process of change. Since any vulnerability may represent in certain circumstances an opportunity, based on an existent analysis, as well as on some personal opinions we shall present the way in which the Romanian academic environment could develop. Believing that nowadays the exchange of experience and the know-how between different branches of the society are the key to obtaining a booster effect that will allow the occurrence of a synergy between them, we are proposing a vision through which the academic environment can take advantages, seizing on the experiences of the business environment, the effect of “leapfrogging” to eliminate the distance between the academic environment and similar systems in other countries with tradition.Such an approach would be not a benchmarking process, but a process of identifying the challenges of the future and discovering through creative means the most adequate methods to support them. After all, if there is a resource of which we can say with certainty that it is abundant in Romania, that resource is creativity. The

    2007-01-01

    Aim: To investigate interpretative accuracy and reporting time for radiologists performing computed tomography (CT) colonography in day-to-day non-academic clinical practice. Materials and methods: Thirteen radiologists from seven centres, who were reporting CT colonography in non-academic daily clinical practice, interpreted a dataset of 15 colonoscopically validated cases in a controlled environment. Ten cases had either a cancer or polyp >10 mm; one case had a medium polyp and four were normal. Correct case categorization and interpretation times were compared using analysis of variance to aggregated results obtained from both experienced observers and observers recently trained using 50 cases, working in an academic environment. The effect of experience was determined using Spearman's rank correlation. Results: Individual accuracy was highly variable, range 53% (95% CI 27-79%) to 93% (95% CI 68-100%). Mean accuracy overall was significantly inferior to experienced radiologists (mean 75 versus 88%, p = 0.04) but not significantly different from recently trained radiologists (p = 0.48). Interpretation time was not significantly different to experienced readers (mean 12.4 min versus 11.7, p = 0.74), but shorter than recently trained radiologists (p = 0.05). There was a significant, positive, linear correlation between prior experience and accuracy (p < 0.001) with no plateau. Conclusion: Accuracy for sub-specialist radiologists working in a non-academic environment is, on average, equivalent to radiologists trained using 50 cases. However, there is wide variability in individual performance, which generally falls short of the average performance suggested by meta-analysis of published data. Experience improves accuracy, but alone is insufficient to determine competence

  12. Corporate knowledge repository: Adopting academic LMS into corporate environment

    The growth of Knowledge Economy has transformed human capital to be the vital asset in business organization of the 21st century. Arguably, due to its white-collar nature, knowledge-based industry is more favorable than traditional manufacturing business. However, over dependency on human capital can also be a major challenge as any workers will inevitably leave the company or retire. This situation will possibly create knowledge gap that may impact business continuity of the enterprise. Knowledge retention in the corporate environment has been of many research interests. Learning Management System (LMS) refers to the system that provides the delivery, assessment and management tools for an organization to handle its knowledge repository. By using the aspirations of a proven LMS implemented in an academic environment, this paper proposes LMS model that can be used to enable peer-to-peer knowledge capture and sharing in the knowledge-based organization. Cloud Enterprise Resource Planning (ERP), referred to an ERP solution in the internet cloud environment was chosen as the domain knowledge. The complexity of the Cloud ERP business and its knowledge make it very vulnerable to the knowledge retention problem. This paper discusses how the company's essential knowledge can be retained using the LMS system derived from academic environment into the corporate model.

    The built environment is important for children׳s health and development. Qualitative research in four communities in Scotland explored with groups of parents of young children their lay perceptions of their local environment with specific reference to its impact upon their children׳s health. Valuing most strong supportive communities; good quality public spaces and social housing, parents׳ key concerns included anti-social behaviour, incivility and a range of locally-specific concerns. As knowledgeable key gatekeepers to children׳s use of home environments and public spaces, parent׳s qualitative lay input is important for the development of children׳s effective use of outdoor spaces and the built environment over the long term.

Schlüchter / Institut für Geologie, Univ. Bern, CH Climate change as seen by a geologist Glaciers are an integrated part of the high altitudes and the high latitudes of our planet. They are sensitive to temperature and moisture changes and adjust their mass balances accordingly. By doing so they interact with their substratum, the geological basement and they produce characteristic imprints of their presence, their variability and their disappearance. In glacial geology and paleoglaciology such imprints of former glaciers are carefully recorded, mapped and, hopefully, dated in order to obtain amplitude and periodicity records of their changes - as forced by changing climate, as we believe. In the upcoming lectures three aspects will be discussed: the last glaciation in the Swiss Alps. A reconstruction is shown based on fieldwor...

    Full Text Available A new research model for simulation software evaluation is proposed consisting of three main categories of criteria: modeling and simulation capabilities of the explored tools, and tools’ input/output analysis possibilities, all with respective sub-criteria. Using the presented model, two discrete event simulation tools are evaluated in detail using the task-centred scenario. Both tools (Arena and ExtendSim were used for teaching discrete event simulation in preceding academic years. With the aim to inspect their effectiveness and to help us determine which tool is more suitable for students i.e. academic purposes, we used a simple simulation model of entities competing for limited resources. The main goal was to measure subjective (primarily attitude and objective indicators while using the tools when the same simulation scenario is given. The subjects were first year students of Master studies in Information Management at the Faculty of Economics in Split taking a course in Business Process Simulations (BPS. In a controlled environment – in a computer lab, two groups of students were given detailed, step-by-step instructions for building models using both tools - first using ExtendSim then Arena or vice versa. Subjective indicators (students’ attitudes were collected using an online survey completed immediately upon building each model. Subjective indicators primarily include students’ personal estimations of Arena and ExtendSim capabilities/features for model building, model simulation and result analysis. Objective indicators were measured using specialised software that logs information on user's behavior while performing a particular task on their computer such as distance crossed by mouse during model building, the number of mouse clicks, usage of the mouse wheel and speed achieved. The results indicate that ExtendSim is well preferred comparing to Arena with regards to subjective indicators while the objective indicators are

    Heat stress is one of the main factors affecting egg production. One way to improve egg production is physical processing of the feed ingredients, allowing for better utilization of nutrients. In this study, the relationship between the corn particle size, measured as the geometric mean diameter (GMD), and thermoregulation was evaluated by determining the effect of the GMD on performance, egg quality, and physiological responses. Feed intake, eggshell quality (weight and thickness), rectal temperature ( T R), respiratory rate ( R R), and surface temperature ( T S) were recorded in sixty 20-week-old naked neck laying hens that were fed corn of different particle sizes. Ambient temperature ( T A) was also recorded during the trial. The GMD of corn particles was determined using a screens granulometer, resulting in sizes of 605, 1,030, and 2,280 μm. The analysis of variance (ANOVA) of a completely randomized design showed a significant effect ( P birds increase their respiratory rate to dissipate excess metabolic heat. This increase in the respiratory rate causes a decrease in the eggshell quality.

    In the longitudinal study presented here, we tested the theoretical assumption that children's task-focused behavior in learning situations mediates the associations between supportive interpersonal environments and academic performance. The sample consisted of 2,137 Finnish-speaking children. Data on supportive interpersonal environments (characterized by authoritative parenting, positive teacher affect toward the child, and peer acceptance) were gathered in Grade 1. The children's task-focused behavior was measured in Grades 2 and 3, and academic performance was measured in Grades 1 and 4. The results supported our assumption by showing that all three supportive environments were positively associated with children's subsequent academic performance via increased task-focused behavior in learning situations. These findings suggest that students' academic performance can be promoted by increasing the support they receive from peers, parents, and teachers because such increased support leads to better task focus in learning tasks.

    Objectives This study was conducted to characterize the relative strength of associations of learning environment perception with academic performance and with personal growth. Methods In 2012-2014 second and third year students at Johns Hopkins University School of Medicine completed a learning environment survey and personal growth scale. Hierarchical linear regression analysis was employed to determine if the proportion of variance in learning environment scores accounted for by personal growth was significantly larger than the proportion accounted for by academic performance (course/clerkship grades). Results The proportion of variance in learning environment scores accounted for by personal growth was larger than the proportion accounted for by academic performance in year 2 [R2Δ of 0.09, F(1,175) = 14.99,  p environment scores shared a small amount of variance with academic performance in years 2 and 3.  The amount of variance between learning environment scores and personal growth was small in year 2 and large in year 3. Conclusions Since supportive learning environments are essential for medical education, future work must determine if enhancing personal growth prior to and during the clerkship year will increase learning environment perception.

    The online learning environment not only affords accessibility to education for health sciences students, but also poses challenges to academic integrity. Technological advances contribute to new modes of academic dishonesty, although there may be a lack of clarity regarding behaviors that constitute academic dishonesty in the online learning environment. To evaluate an educational intervention aimed at increasing knowledge and improving attitudes about academic integrity in the online learning environment among health sciences students. A quasi-experimental study was conducted using a survey of online learning knowledge and attitudes with strong reliability that was developed based on a modified version of a previously developed information technology attitudes rating tool with an added knowledge section based on the academic integrity statement. Blended-learning courses in a university health sciences center. 355 health sciences students from various disciplines, including nursing, pre-medical, and exercise physiology students, 161 in the control group and 194 in the intervention group. The survey of online learning knowledge and attitudes (SOLKA) was used in a pre-post test study to evaluate the differences in scores between the control group who received the standard course introduction and the intervention group who received an enhanced educational intervention about academic integrity during the course introduction. Post-intervention attitude scores were significantly improved compared to baseline scores for the control and intervention groups, indicating a positive relationship with exposure to the information, with a greater improvement among intervention group participants (pacademic integrity in the online environment. Emphasis should be made about the importance of academic integrity in the online learning environment in preparation for professional behavior in the technologically advancing health sciences arena.

    Terrell, Pamela; Watson, Maggie

    2018-04-05

    As part of this clinical forum on curriculum-based intervention, the goal of this tutorial is to share research about the importance of language and literacy foundations in natural environments during emergent literacy skill development, from infancy through preschool. Following an overview of intervention models in schools by Powell (2018), best practices at home, in child care, and in preschool settings are discussed. Speech-language pathologists in these settings will be provided a toolbox of best emergent literacy practices. A review of published literature in speech-language pathology, early intervention, early childhood education, and literacy was completed. Subsequently, an overview of the impact of early home and preschool literacy experiences are described. Research-based implementation of best practice is supported with examples of shared book reading and child-led literacy embedded in play within the coaching model of early intervention. Finally, various aspects of emergent literacy skill development in the preschool years are discussed. These include phonemic awareness, print/alphabet awareness, oral language skills, and embedded/explicit literacy. Research indicates that rich home literacy environments and exposure to rich oral language provide an important foundation for the more structured literacy environments of school. Furthermore, there is a wealth of evidence to support a variety of direct and indirect intervention practices in the home, child care, and preschool contexts to support and enhance all aspects of oral and written literacy. Application of this "toolbox" of strategies should enable speech-language pathologists to address the prevention and intervention of literacy deficits within multiple environments during book and play activities. Additionally, clinicians will have techniques to share with parents, child care providers, and preschool teachers for evidence-based literacy instruction within all settings during typical daily

    Past practices of informal sample collections and spreadsheets for data and sample management fall short of best-practice models for biobanking, and are neither cost effective nor efficient to adequately serve the needs of large research studies. The biobank of the Sydney Brenner Institute for Molecular Bioscience serves as a bioresource for institutional, national and international research collaborations. It provides high-quality human biospecimens from African populations, secure data and sample curation and storage, as well as monitored sample handling and management processes, to promote both non-communicable and infectious-disease research. Best-practice guidelines have been adapted to align with a low-resource setting and have been instrumental in the development of a quality-management system, including standard operating procedures and a quality-control regimen. Here, we provide a summary of 10 important considerations for initiating and establishing an academic research biobank in a low-resource setting. These include addressing ethical, legal, technical, accreditation and/or certification concerns and financial sustainability.

    1999-06-01

    This research investigates the impact of managed health care on academic medical centers in the United States. Academic medical centers hold a unique position in the U.S. health care system through their missions of conducting cutting-edge biomedical research, pursuing clinical and technological innovations, providing state-of-the-art medical care and producing highly qualified health professionals. However, policies to control costs through the use of managed care and limiting resources are detrimental to academic medical centers and impede the advancement of medical science. To survive the threats of managed care in the health care environment, academic medical centers must rely on their upper level managers to derive successful strategies. The methods used in this study include qualitative approaches in the form of key informants and case studies. In addition, a survey questionnaire was sent to 108 CEOs in all the academic medical centers in the U.S. The findings revealed that managers who perform the liaison, monitor, entrepreneur and resource allocator roles are crucial to ensure the survival of academic medical centers, so that academic medical centers can continue their missions to serve the general public and promote their well-being.

    The aim of this study was to evaluate the regional differences in the surface temperature of Naked Neck hens that were subjected to different temperatures in a semi-arid environment. The surface temperature was measured in four body regions (face, neck, legs and feathered area) of 60 Naked Neck hens. The following environmental variables were measured at the center of the shed: the black globe temperature (T G ), air temperature (T A ), wind speed (U) and relative humidity (R H ). The T A was divided into three classes: 1 (24.0-26.0 °C), 2 (26.1-28.9 °C) and 3 (29.0-31.0 °C). An analysis of variance was performed by the least squares method and a comparison of the means by the Tukey-Kramer test. The results showed a significant effect of T A class, the body region and the interaction between these two effects on the surface temperature. There was no significant difference between the T A classes for the face and neck. The legs and feathered area showed significant differences between the T A classes. Regarding the effect of body regions within each T A class, there was a significant difference among all regions in the three T A classes. In all T A classes the neck had the highest average followed by the face and legs. The feathered area showed the lowest average of the different T A classes. In conclusion, this study showed that there are regional differences in the surface temperature of Naked Neck hens, with the legs acting as thermal windows.

  5. Social environment during egg laying: Changes in plasma hormones with no consequences for yolk hormones or fecundity in female Japanese quail, Coturnix japonica.

    Directory of Open Access Journals (Sweden)

    Esther M A Langen

    Full Text Available The social environment can have profound effects on an individual's physiology and behaviour and on the transfer of resources to the next generation, with potential consequences for fecundity and reproduction. However, few studies investigate all of these aspects at once. The present study housed female Japanese quail (Coturnix japonica in pairs or groups to examine the effects on hormone concentrations in plasma and yolk and on reproductive performance. Circulating levels of androgens (testosterone and 5-α-dihydrotestosterone and corticosterone were measured in baseline samples and after standardised challenges to assess the responsiveness of the females' endocrine axes. Effects of the social environment on female fecundity were analysed by measuring egg production, egg mass, fertilization rates, and number of hatched offspring. Counter to expectation, females housed in pairs had higher plasma androgen concentrations and slightly higher corticosterone concentrations than females housed in groups, although the latter was not statistically significant. Pair vs. group housing did not affect the females' hormonal response to standardised challenges or yolk testosterone levels. In contrast to previous studies, the females' androgen response to a gonadotropin-releasing hormone challenge was not related to yolk testosterone levels. Non-significant trends emerged for pair-housed females to have higher egg-laying rates and higher fertility, but no differences arose in egg weight or in the number, weight or size of hatchlings. We propose that our unexpected findings are due to differences in the adult sex ratio in our social treatments. In pairs, the male may stimulate female circulating hormone levels more strongly than in groups where effects are diluted due to the presence of several females. Future studies should vary both group size and sex composition to disentangle the significance of sexual, competitive and affiliative social interactions for

    2017-01-01

    Abnormal activity detection plays a crucial role in surveillance applications, and a surveillance system that can perform robustly in an academic environment has become an urgent need. In this paper, we propose a novel framework for an automatic real-time video-based surveillance system which can simultaneously perform the tracking, semantic scene learning, and abnormality detection in an academic environment. To develop our system, we have divided the work into three phases: preprocessing phase, abnormal human activity detection phase, and content-based image retrieval phase. For motion object detection, we used the temporal-differencing algorithm and then located the motions region using the Gaussian function. Furthermore, the shape model based on OMEGA equation was used as a filter for the detected objects (i.e., human and non-human). For object activities analysis, we evaluated and analyzed the human activities of the detected objects. We classified the human activities into two groups: normal activities and abnormal activities based on the support vector machine. The machine then provides an automatic warning in case of abnormal human activities. It also embeds a method to retrieve the detected object from the database for object recognition and identification using content-based image retrieval. Finally, a software-based simulation using MATLAB was performed and the results of the conducted experiments showed an excellent surveillance system that can simultaneously perform the tracking, semantic scene learning, and abnormality detection in an academic environment with no human intervention.

    Organizational effects on job satisfaction, burnout, work-life balance, and perceived support have not been studied in the context of the clinical learning environment. We evaluated the relationship between academic resources and resident well-being, the clinical learning environment, and in-service examination performance of surgical residents. Residents of general surgery and surgical specialty programs were recruited from March 2016 through June 2016 across the Southeast, Mid-Atlantic, and Northeast regions. Program directors were asked to allow distribution of a paper survey or to forward an electronic survey link onto residents. Five dichotomous questions were asked regarding access to academic resources. Validated measures were obtained assessing resident well-being and perceived clinical learning environment. Data were analyzed through t-tests and chi-squared test of independence. We received 276 respondents across 50 programs. Residents perceiving adequate support to succeed had less burnout (P = 0.008), better resilience (P = 0.009), better job satisfaction (P workplace climate (P < 0.001), better organizational support (P < 0.001), and were more likely to have high performance on the in-service examination (P = 0.001). Specific resources including educational stipends, review questions, in-service board prep, and support for poor performers correlated with improved well-being and perceived clinical learning environment. Provision of academic resources has implications beyond in-service examination performance, correlating with improved resident well-being and perceptions of the clinical learning environment.

    Full Text Available Outside an academic setting, telecommuting has become fairly popular in recent years. However, research on telecommuting practices within a higher education environment is fairly sparse, especially within the higher distance education sphere. Drawing on existing literature on telecommuting and the outcome of a valuation study on the success of an experimental telecommuting programme at the largest distance education institution in South Africa, this article presents discerning findings on telecommuting practices. In fact, the research builds on evolutionary telecommuting assessment methods of the direct or indirect effect (work based and affective impact (emotional on multiple stakeholder groups. This holistic approach allowed for comparative analysis between telecommuting and nontelecommuting academics with regard to the impact of telecommuting practices. The research reveals high levels of support for telecommuting practices that are associated with high levels of work productivity and satisfaction, lower levels of emotional and physical fatigue, and reduced work stress, frustration, and overload. The study also reveals higher levels of student satisfaction with academic support from telecommuters than nontelecommuters. Overall, the critique presents insightful findings on telecommuting practices within an academic setting, which clearly signal a potential for a shift in the office culture of higher distance education institutions in the years to come. The study makes a significant contribution to a limited collection of empirical research on telecommuting practices within the higher distance education sector and guides institutions in refining and/or redefining future telecommuting strategies or programmes.

    Harmon, Rebecca B; DeGennaro, Gina; Norling, Meg; Kennedy, Christine; Fontaine, Dorrie

    In 2005 the American Association of Critical Care Nurses defined six Healthy Work Environment (HWE) standards for the clinical setting (AACN, 2005), which were reaffirmed and expanded in 2016 (AACN, 2016). These clinical standards were adapted for use in the academic setting by Fontaine, Koh, and Carroll in 2012. The intention of this article is threefold: to present a revised version of the academic workplace standards which are appropriate for all School of Nursing (SON) employees, staff as well as faculty; to proposes the addition of a seventh standard, self-care, which provides the foundation for all standards; and to describe the continuing implementation of these seven standards at the University of Virginia School of Nursing (UVA SON).

    This study examined how the family environment predicts long-term academic and behavioral functioning in school following traumatic brain injury (TBI) in early childhood. Using a concurrent cohort, prospective design, 15 children with severe TBI, 39 with moderate TBI, and 70 with orthopedic injury (OI) who were injured when they were 3-7 years of age were compared on tests of academic achievement and parent and teacher ratings of school performance and behavior on average 6.83 years postinjury. Soon after injury and at the longer term follow-up, families completed measures of parental psychological distress, family functioning, and quality of the home environment. Hierarchical linear regression analyses examined group differences in academic outcomes and their associations with measures of the early and later family environment. The severe TBI group, but not the moderate TBI group, performed worse than did the OI group on all achievement tests, parent ratings of academic performance, and teacher ratings of internalizing problems. Higher quality early and late home environments predicted stronger academic skills and better classroom behavior for children with both TBI and OI. The early family environment more consistently predicted academic achievement, whereas the later family environment more consistently predicted classroom functioning. The quality of the home environment predicted academic outcomes more strongly than did parental psychological distress or family functioning. TBI in early childhood has long-term consequences for academic achievement and school performance and behavior. Higher quality early and later home environments predict better school outcomes for both children with TBI and children with OI. (PsycINFO Database Record (c) 2017 APA, all rights reserved).

    The culture of academic medical institutions impacts trainee education, among many other faculty and patient outcomes. Disrespectful behavior by faculty is one of the most challenging and common problems that, left unattended, disrupts healthy work and learning environments. Conversely, a respectful environment facilitates learning, creates a sense of safety, and rewards professionalism. The authors developed surveys and an intervention in an effort to better understand and improve climate concerns among health sciences faculty at the University of California, San Diego (UCSD), a research-intense, public, academic medical center. An online "climate survey" of all UC San Diego health sciences faculty was conducted in 2011-2012. A strategic campaign to address the behavioral issues identified in the initial survey was subsequently launched. In 2015, the climate was re-evaluated in order to assess the effectiveness of the intervention. A total of 478 faculty members (223 women, 235 men, 35 % of faculty) completed the baseline survey, reporting relatively low levels of observed sexual harassment (7 %). However, faculty reported concerning rates of other disruptive behaviors: derogatory comments (29 %), anger outbursts (25 %), and hostile communication (25 %). Women and mid-level faculty were more likely to report these behavioral concerns than men and junior or senior colleagues. Three years after an institutional strategy was initiated, 729 faculty members (50 % of the faculty) completed a follow-up survey. The 2015 survey results indicate significant improvement in numerous climate factors, including overall respectful behaviors, as well as behaviors related to gender. In order to enhance a culture of respect in the learning environment, institutions can effectively engage academic leaders and faculty at all levels to address disruptive behavior and enhance positive climate factors.

    Full Text Available While the organizational culture and the professional culture are centered on serving the customer, the accounting and audit culture are focused on helping all accounting users. Mainly, culture operates with information that is prepared, disclosed and, in the same time, interpreted by its receivers and senders. The way each of us interprets the information or offers judgments and opinions, depends on our referential framework, that is a combination of our educational, developmental intellectual culture and work related experiences. The present study tries to point out how these concepts are understood by students from the academic environment and how knowledge gathered during their educational cycle can be transferred into practice.

    In the U.S., enrollment and graduation rates of baccalaureate nursing programs are slowly increasing. Rigorous program requirements can be overwhelming for students who may have difficulty adjusting to curriculum demands. Faculty who help students to adjust may also build a supportive learning environment that promotes autonomous motivation, improves engagement, and strengthens academic performance. Students may also experience well-being and autonomy when they feel supported and when their needs are met. The aim of this study was to investigate nursing students' autonomy support environments and autonomous motivation (measured as spirituality), and the influence on engagement and academic performance. A cross-sectional correlational design using a convenience sample of 150 nursing students in the last year of a baccalaureate nursing program was used. Participants were recruited from four universities in Florida and data collection occurred over three months. All participants were enrolled in the last year of their baccalaureate nursing program with an average Grade Point Average (GPA) of 3.36. The learning climate alone was moderately supportive of student motivation (M=70.60, SD=18.99). No significant relationship between the autonomy support environment and autonomous motivation (r=.034, p=.676) was found. Correlations and regression analysis of autonomous motivation and work engagement were significant (F (2, 147)=28.28, p=.000). Comparison of participant groups from each university independently revealed supportive learning environments. Strategies to promote autonomy must be developed and implemented as a means of ensuring a favorable learning environment. Future research may include the investigation of spirituality and autonomous motivation as two separate variables. Copyright © 2016 Elsevier Ltd. All rights reserved.

    Objective Learning environment has a significant role in determining students’ academic achievement and learning. The aim of this study is to investigate the viewpoints of undergraduate medical sciences students on the learning environment using the Dundee Ready Education Environment Measure (DREEM) at Rafsanjan University of Medical Sciences (RUMS). Methods The descriptive cross-sectional study was performed on 493 medical sciences students in the following majors: nursing, midwifery, radiology, operating room nursing, laboratory sciences, medical emergency, and anesthesia. The DREEM questionnaire was used as a standard tool. Data were analyzed using SPSS (v17) software. Student’s t-tests and analysis of variance (ANOVA) statistical tests were used. Results The mean of the achieved scores in the five domains was 113.5 out of 200 (56.74%), which was considered to be more positive than negative. The total mean scores for perception of learning, teaching, and atmosphere were 27.4/48 (57.24%), 24.60/44 (55.91%), and 26.8/48 (55.89%), respectively. Academic and social self-perceptions were 20.5/32 (64.11%) and 15.7/28 (56.36%), respectively. The total DREEM scores varied significantly between courses (Penvironment. The differences between courses and their study pathway should be further investigated by analysis of specific items. Our results showed that it is essential for faculty members and course managers to make more efforts toward observing principles of instructional designs, to create an appropriate educational environment, and to reduce deficits in order to provide a better learning environment with more facilities and supportive systems for the students.

    Full Text Available Task based design is considered one of the effective ways of designing functional software. It is generally accepted that tasks play an important role in system and user interface design. Identifying the user's tasks enables the designer to construct user interfaces reflecting the tasks' properties, including efficient usage patterns, easy-to-use interaction sequences, and powerful assistance features. In this paper, we present a prototype of a Digital Work Environment (DWE to support a task-oriented design to information access in a typical community of academic users. The resources in DWE are organized according to specific tasks performed by the research students and staff in the Division of Information Studies of Nanyang Technological University, Singapore. The tasks and resources were elicited based on the needs of faculty and students through interviews and focus groups. Examples of these tasks include preparation of a new course outline, setting of examination papers, preparation of reading lists and assignments, conducting literature reviews and writing dissertations. This paper discusses the problems of digital library users in an academic environment, highlights task oriented projects and focuses on the task of preparing and writing a Master dissertation. It highlights the importance of task based design in assisting and helping students and instructors from the time of selecting the research project to the time of submitting the final bound copies of the dissertation.

    Documentation of research data plays a key role in the biomedical engineering innovation processes. It makes an important contribution to the protection of intellectual property, the traceability of results and fulfilling the regulatory requirement. Because of the increasing digitalization in laboratories, an electronic alternative to the commonly-used paper-bound notebooks could contribute to the production of sophisticated documentation. However, compared to in an industrial environment, the use of electronic laboratory notebooks is not widespread in academic laboratories. Little is known about the acceptance of an electronic documentation system and the underlying reasons for this. Thus, this paper aims to establish a prediction model on the potential preference and acceptance of scientists either for paper-based or electronic documentation. The underlying data for the analysis originate from an online survey of 101 scientists in industrial, academic and clinical environments. Various parameters were analyzed to identify crucial factors for the system preference using binary logistic regression. The analysis showed significant dependency between the documentation system preference and the supposed workload associated with the documentation system (plaboratory notebook before implementation.

    Media can influence aspects of a child's physical, social, and cognitive development; however, the associations between a child's household media environment, media use, and academic achievement have yet to be determined. To examine relationships among a child's household media environment, media use, and academic achievement. During a single academic year, data were collected through classroom surveys and telephone interviews from an ethnically diverse sample of third grade students and their parents from 6 northern California public elementary schools. The majority of our analyses derive from spring 2000 data, including academic achievement assessed through the mathematics, reading, and language arts sections of the Stanford Achievement Test. We fit linear regression models to determine the associations between variations in household media and performance on the standardized tests, adjusting for demographic and media use variables. The household media environment is significantly associated with students' performance on the standardized tests. It was found that having a bedroom television set was significantly and negatively associated with students' test scores, while home computer access and use were positively associated with the scores. Regression models significantly predicted up to 24% of the variation in the scores. Absence of a bedroom television combined with access to a home computer was consistently associated with the highest standardized test scores. This study adds to the growing literature reporting that having a bedroom television set may be detrimental to young elementary school children. It also suggests that having and using a home computer may be associated with better academic achievement.

    Full Text Available The realisation of the advantages offered by e-learning accompanied by the use of various emerging information technologies has resulted in a noticeable shift by academia towards e-learning. An analysis of the use, knowledge and adoption of emerging technologies by academics in an Open Distance Learning (ODL environment at the University of South Africa (UNISA was undertaken in this study. The aim of the study was to evaluate the use, knowledge and adoption of emerging e-learning technologies by the academics from the selected schools. The academics in the Schools of Arts, Computing and Science were purposively selected in order to draw on views of academics from different teaching and educational backgrounds. Questionnaires were distributed both electronically and manually. The results showed that academics in all the Schools were competent at the use of information technology tools and applications such as emailing, word-processing, Internet, myUnisa (UNISA’s online teaching platform, and Microsoft PowerPoint and Excel. An evaluation of the awareness of different emerging technological tools showed that most academics were aware of Open Access Technologies, Social Networking Sites, Blogs, Video Games and Microblogging Platforms. While the level of awareness was high for these technologies, the use by the academics was low. At least 62.3% of the academics indicated willingness to migrate to online teaching completely and also indicated the need for further training on new technologies. A comparison of the different schools showed no statistically significant difference in the use, knowledge and willingness to adopt technology amongst the academics.

    The aim was to investigate the prevalence of health problems and work environment problems and how these are associated with subjective production loss among women and men at an academic workplace. An additional aim was to investigate whether there were differences between women and men according to age group, years at current workplace, academic rank or managerial position. A questionnaire was sent in 2011 to all employees at a Swedish university (n = 5144). Only researchers and teachers were included in the study (n = 3207). Spearman correlations were performed to investigate differences in health and work environment problems. Employees who reported having experienced work environment or health problems in the previous seven days (n = 1475) were included in the analyses in order to investigate differences in subjective production loss. This was done using Student's t-test, One-way Anova and generalized linear models. The response rate was 63% (n = 2022). A total of 819 academic staff (40% of the population) reported experiencing either health problems, work environment problems or both during the previous seven days. The prevalence of health problems only or a combination of work environment and health problems was higher among women than men (p-value ˂0.05). This was especially the case for younger women, those in lower academic positions and those who had worked for fewer years at their current workplace. No difference was found for work environment problems. The majority of the employees who reported problems said that these problems affected their ability to perform at work (84-99%). The average production loss varied between 31 and 42% depending on the type of problem. Production loss due to health-related and work-environment related problems was highest among junior researchers and managers. No significant difference between men and women was found in the level of production loss. Subjective production loss in academia can be associated

    The aim of the study is to ascertain the level of depression among university students across gender, academic stream, semesters, perception of family environment and relationship with parents, academic performance, and family income. In addition, the study examines the association between students' perceived university academic environment, living arrangements, personal issues, and depression. Seven hypotheses were formulated for verification. A total of 717 students were recruited following the multistage cluster sampling method, and data were collected by a specially designed structured questionnaire, academic achievement record and a standardized University Students Depression Inventory. Findings disclosed that 37.7%, 13.1%, and 2.4% of the students were suffering from moderate, severe, and extremely severe depression. A significant difference was found across semester, that is, semester II students reported a higher level of depression than semester III students. So far as academic stream is concerned, students from humanities and social science were found to be suffering from more depression compared to students from science and management streams. The study further disclosed that the students who reported positive views about the university academic environment and living arrangements had lower level of depression compared to their counterparts. Personal resilience's such as being able to sharing personal problems with others and doing regular exercise were found to be associated with positive mental health. The findings of the study emphasize the need for immediate mental health support services for about 15.6% of the students who were either suffering from severe or extremely severe depression at the University.

    Food-insecure (FIS) adolescents struggle in school and with health and mental health more often than food-secure (FS) adolescents. Rural communities experience important disparities in health, but little is known about rural FIS adolescents. This study aims to describe select characteristics of rural adolescents by food-security status. Baseline analysis using data from a randomized trial to increase school breakfast participation (SBP) in rural Minnesota high schools. Students completed a survey regarding food security, characteristics, and home and school environments. Schools provided academic data and staff measured height and weight. Food security was dichotomized as FS vs FIS. Bivariate analysis, multivariate linear/logistic regression, and testing for interaction of food security and sex were performed. Food-insecure adolescents reported poorer health, less exercise, had lower grades, and higher SBP (p breakfast (p = .05). All associations except reported benefits remained significant after adjustment. Interactions were identified with girls' grade point average and with boys' caloric and added sugar intake. Negative associations among food insecurity and positive youth development are identified in our sample. Policy and environmental strategies should address the complexities of these associations, including exploration of the role of school meals. © 2016, American School Health Association.

    2011-01-01

    In recent years, the administration of Meharry Medical College, School of Medicine (SOM), Nashville, Tennessee, recognized the need to modify the curriculum to help improve student academic performance especially on the National Board of Medical Examiners (NBME) US Medical Licensing Examination (USMLE) steps 1 and 2. Thus, a number of changes occurred with respect to the traditional curriculum in the SOM, resulting in an integrated organ system-based curriculum design. The change in the learning environment was studied to determine the impact on performance after the introduction of the integrated organ system-based curriculum as compared to that of the traditional curriculum. With the utilization of a cadre of variables, it was believed that the strategic impact anticipated would provide a predictive validity profile to assist in the identification of students "at risk" of failure so that proactive intervention methodology could be made available to facilitate the students' successful progression during matriculation in the SOM. The purpose of this study was to analyze whether students trained with the integrated organ systems curriculum perform better than students trained with the traditional medical school curriculum on the medical education preclinical subject board examinations, and the NBME USMLE steps 1 and 2 examinations. From the 584 students studied in the control group (graduation classes for years 2005, 2006, and 2007) and the intervention group (graduation classes for years 2008, 2009, and 2010), significant improvement in performance on the NBME USMLE steps 1 and 2 examinations was noted following the introduction of the integrated organ system-based curriculum particularly among "at-risk" students. Data access availability from the School of Medicine of Meharry Medical College automatically gave reason for a preferential comparative relationship and study of the resulting strategic impact on cohorts graduating in years 2005-2010.

    This study investigated academic achievement among adolescents exposed to violence, sexual abuse and bullying. Moreover, we sought to determine the individual and contextual influence of the adolescents' school environment in terms of bullying, classmate relationships and teacher support on academic achievement. Finally, we wished to assess whether school-level influence is different for the adolescents exposed to violence and sexual abuse versus the adolescents not exposed to these forms of abuse. This is a cross-sectional study of a sample of 7,343 adolescents between the ages of 15 and 16 from 56 schools in Oslo, Norway. We investigated associations between violence, sexual abuse, bullying, classmate relationships, teacher support and academic achievement. Linear regression was used to investigate associations on the individual level. Multilevel analyses were conducted to test for school level differences while controlling for both individual and contextual factors. On the individual level, all combinations of violence and sexual abuse categories were significantly associated with lower grades. This was also true for bullying, while teacher support resulted in better grades. At the school level, the analysis showed that students in schools with higher levels of bullying performed worse academically. Each unit of increment in bullying in school corresponded to an average 0.98 point decrease in grades (pschool environment and adolescent exposure to violence, indicating that the school environment affects all students. Factors on both levels can contribute to reduced grades. This stresses the need to investigate individual and contextual factors simultaneously when examining academic achievement. Our results indicated that students attending schools with higher levels of bullying may show poorer school performance. This was true for all students regardless of previous exposure to violence and sexual abuse. This emphasizes the need for preventive efforts that focus

  20. Public awareness of testicular cancer and testicular self-examination in academic environments: a lost opportunity

    Full Text Available BACKGROUND: Although testicular cancer is the most common cancer among 18- to 50-year-old males, healthcare providers seldom teach testicular self-examination techniques to clients, thus potentially missing opportunities for early detection. This form of cancer is easily diagnosable by testicular self-examination and is 96% curable if detected early. Periodic self-examination must be performed for early detection. Knowledge deficits and sociocultural norms contribute to low levels of health-related knowledge in most patients, resulting in undue delays before seeking medical advice. OBJECTIVE: Our aim is to assess the level of awareness of testicular cancer and the prevalence of the practice of testicular self-examination in academic environments to enable appropriate interventions. METHOD: A cross-sectional survey was administered to 750 consecutive males aged 18-50 years in three tertiary institutions in Port Harcourt from October 2008 to April 2009. RESULT: Knowledge or awareness of testicular cancer was poor. Almost all of the respondents were unaware that testicular lumps may be signs of cancer. A lump was typically construed as a benign carbuncle or something that could resolve spontaneously. The main factor contributing to respondents' lack of knowledge of testicular cancer was that few reported that they were "ever taught about testicular self-examination." CONCLUSION: Young adult men are unaware of their risk for testicular cancer, which is the most common neoplasm in this age group. Healthcare providers are not informing them of this risk, nor are they teaching them the simple early detection technique of self-examination of the testes.

  1. Nurture net of nature: Re-evaluating the role of shared environments in academic achievement and verbal intelligence.

    Prominent authors in the behavioral genetics tradition have long argued that shared environments do not meaningfully shape intelligence and academic achievement. However, we argue that these conclusions are erroneous due to large violations of the additivity assumption underlying behavioral genetics methods - that sources of genetic and shared and nonshared environmental variance are independent and non-interactive. This is compounded in some cases by the theoretical equation of the effective and objective environments, where the former is defined by whether siblings are made more or less similar, and the latter by whether siblings are equally subject to the environmental characteristic in question. Using monozygotic twin fixed effects models, which compare outcomes among genetically identical pairs, we show that many characteristics of objectively shared environments significantly moderate the effects of nonshared environments on adolescent academic achievement and verbal intelligence, violating the additivity assumption of behavioral genetic methods. Importantly, these effects would be categorized as nonshared environmental influences in standard twin models despite their roots in shared environments. These findings should encourage caution among those who claim that the frequently trivial variance attributed to shared environments in behavioral genetic models means that families, schools, and neighborhoods do not meaningfully influence these outcomes.

    Full Text Available Based on the concept of adaptive hypermedia, the webCT platform was used to design a learning virtual environment that would allow students’ interaction of different support materials with their usual styles of learning. GA Latin Square design was used to determine the role that environment and learning styles, along with intrinsic motivation, played on academic performance, navigation patterns, and number of visits to the support materials. The study showed an important difference in academic performance in favor of the Balanced group. Intrinsic motivation was the main explicative factor for the differences found beyond learning styles. The conclusion was that there are differences in the way of using the objects of learning, and that there are differentiated patterns to access the support material, depending on the students’ learning styles.

    African American students are overrepresented in special education. Ecological systems theory, social cognitive theory, and a literature review demonstrate that children's environments, particularly school, and self-efficacy impact the educational outcomes of African American children. Interventions have aimed to improve children's environmental resources and efficacy. The aim of this study was to assess the impact of environment, efficacy beliefs, and the Nurse-Family Partnership intervention on the educational achievements of African American children in special education. A secondary data analysis of 126 African American children in special education found that self-efficacy and the number of hours spent in special education were associated with their academic achievement.

    Corrosion in power plant equipment is to a large extent a result of poor lay-up procedures. This applies for all equipment on the water and steam side e.g. condensers, boilers, turbines, heat exchangers etc. In theory, lay-up procedures are quite straightforward. The main objective is to avoid a combination of water and oxygen on the steel surfaces within the system. When using dry lay-up procedure, a totally dry environment is essential. The corrosion of steel cannot take place if there is no humidity; in spite of the abundance of oxygen i.e. air. As an alternative the steam side system can be purged with nitrogen so that no air ingress can take place. When using wet lay-up procedures it is important to achieve an oxygen free environment. Creating a slight over-pressure thus avoiding air in leakage can achieve this. Oxygen scavengers might be used as an alternative. Usually problems of maintaining the above mentioned conditions are rarely of technical art. More likely it is due to a lack of knowledge and commitment or short sighted economical considerations. This report summarises the experiences gathered at several visits at plants and discussions with vendors, users and consultants in the power industry. In addition to that, guidelines from well-reputed organisations, international and domestic, have been studied. In many cases the power plant managers believe they have proper lay-up routines but often the routines just regard long time lay-up. This may be regarded as the most important case. However, a number of shorter plant outages in combination with poor lay-up routines can result in severe damages. There is a consensus that a proper lay-up can only be achieved by plant specific lay-up procedures. Each unit is unique in terms of needs and requirements. In order to have as low corrosion as possible a systematic review to evaluate and revise lay-up procedures is preferred. A high in-house knowledge of the power plant enhances the possibility to maintain the

    Full Text Available The major aim of this study was to investigate the effect of insecurity of school environment on the academic performance of secondary school students in Imo state, Nigeria. A total of 1000 made up of 500 each of male and female students responded to a self-structured validated questionnaire designed for the study. Two research questions and two hypotheses were formulated to guide the study. Means and standard deviations were calculated to answer the research questions and independent samples t-tests were used for testing the hypotheses. Major findings revealed that insecurity of school environment significantly affects the academic performance of secondary school students while students’ gangsterism, smoking of Indian hemp, abusing other hard drugs, cult and related violent activities were some of the factors that constituted insecurity of the school environment which eventually cause boys to leave school and join trading while leading girls to drop out and settle for marriage. Based on the findings, it was recommended that owners of schools and other stakeholders in education should take bold steps to fence and protect school environments from intruders to ensure safety of the students.

  7. Safety-technical lay-out of the operational environment of a high-power spallation target system of the megawatt class with mercury as target material

    Butzek, M.

    2005-06-01

    This thesis is concerning the safety relevant layout of the environment of a mercury based 5-Megawatt-spallation target. All safety relevant aspects related to construction, operation and dismantling as well as economical issues were taken into account. Safety concerns are basically driven by the toxic and radioactive inventory as well as the kind and intensity of radiation produced by the spallation process. Due to significant differences in inventory and radiation between a spallation source and a fission reactor, for the design of the spallation source mentioned above the safety philosophy of a fission reactor must not be used unchanged. Rather than this a systematic study of all safety related boundary conditions is necessary. Within this thesis all safety relevant boundary conditions for this specific type of machine are given. Beside the spatial distribution of different areas inside the target station, influence of medias to be used as well as arising radiation and handling requirements are discussed in detail. A general layout of the target station is presented, serving as a basis for all further component and system development. An enclosure concept for the target station was developed, taking into account the safety relevant issues concerning the mercury used as target materials, the water cooling loops containing massive amounts of tritium as well as the materials used for the moderators potentially forming explosive mixtures. Concept and detailed technical layout of the enclosure system was chosen to guarantee safe operation of the source as well as taking care of requirement arising for handling needs. For design of the shielding different suitable materials have been discussed. A design for assembling the shielding is shown taking into account the safety relevant requirements during operation as well as during dismantling. The neutron beam shutters, buried inside the shielding were designed to optimize handling and positioning issued of the inner part

    Parker, Mary Jo

    This study investigated the effects of a shared, Intranet science environment on the academic behaviors of problem-solving and metacognitive reflection. Seventy-eight subjects included 9th and 10th grade male and female biology students. A quasi-experimental design with pre- and post-test data collection and randomization occurring through assignment of biology classes to traditional or shared, Intranet learning groups was employed. Pilot, web-based distance education software (CourseInfo) created the Intranet learning environment. A modified ecology curriculum provided contextualization and content for traditional and shared learning environments. The effect of this environment on problem-solving, was measured using the standardized Watson-Glaser Critical Thinking Appraisal test. Metacognitive reflection, was measured in three ways: (a) number of concepts used, (b) number of concept links noted, and (c) number of concept nodes noted. Visual learning software, Inspiration, generated concept maps. Secondary research questions evaluated the pilot CourseInfo software for (a) tracked user movement, (b) discussion forum findings, and (c) difficulties experienced using CourseInfo software. Analysis of problem-solving group means reached no levels of significance resulting from the shared, Intranet environment. Paired t-Test of individual differences in problem-solving reached levels of significance. Analysis of metacognitive reflection by number of concepts reached levels of significance. Metacognitive reflection by number of concept links noted also reach significance. No significance was found for metacognitive reflection by number of concept nodes. No gender differences in problem-solving ability and metacognitive reflection emerged. Lack of gender differences in the shared, Intranet environment strongly suggests an equalizing effect due to the cooperative, collaborative nature of Intranet environments. Such environments appeal to, and rank high with, the female

    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.

    2016-10-01

    Full Text Available Orientation: Institutions of higher learning in South Africa are fast embracing performance management system (PMS as a mechanism for the achievement of teaching excellence and enhancement of research productivity. However, literature provided evidence to show that application of PMS in the private sector had failed to drive competition, efficiency and productivity. Research purpose: The main purpose of this article was to evaluate the perception of academic staff members of an open distance learning institution regarding the implementation of a PMS. Motivation for the study: PMS as a mechanism through which performance of academics is measured has been described as inconsistent with the long tradition of academic freedom, scholarship and collegiality in the academy. Moreso, previous research on the implementation of PMS was limited to private sector organisations, thus resulting in the dearth of empirical literature relating to its practice in service-driven public sector institutions. Research design, approach and method: The article adopted a quantitative research approach using census survey methodology. Data were collected from 492 academic staff from the surveyed institution using a self-developed questionnaire that was tested for high content validity with a consolidated Cronbach’s alpha value of 0.83. Data were analysed using a onesample t-test because of the one-measurement nature of the variable under investigation. Main findings: Major findings of the study indicated that respondents were satisfied with the implementation of the PMS by management. However, the payment of performance bonuses was not considered as sufficiently motivating, thus necessitating a pragmatic review by management. Practical/managerial implications: The findings of this article provided a practical guide to managers on the implementation and management of PMS as an employee performance reward mechanism in non-profit and service-oriented organisations

    This article addresses survival strategies of academic health centers (AHCs) in responding to market pressures and government reforms. Using six case studies of AHCs, the study links strategic changes in structure and management to managerial role performance. Utilizing Mintzberg's classification of work roles, the roles of liaison, monitor, entrepreneur, and resource allocator were found to be used by top-level managers as they implement strategies to enhance the viability of their AHCs. Based on these new roles, the study recommends improving management practices through education and training as well as changing organizational culture to support management decision making and foster the continued growth of managers and their AHCs.

    Nursing education is a process that includes theoretical and practical learning and requires the acquisition of theoretical knowledge and skill. Nursing students need a good clinical practice environment in order to apply their knowledge and skills due to the fact that the clinical practice settings play an important role in the nursing profession. This study was carried out in an effort to explore nursing students' perception of the clinical learning environment and its association with academic motivation and clinical decision making. A descriptive survey design was used. This study was conducted in Giresun University in Turkey. Participants were second-, third- and fourth-year undergraduate students (n=222) in the Bachelor of Nursing Science Degree in the academic spring term of 2014-2015. The data was collected using the 'Clinical Learning Environment Scale', the 'Academic Motivation, and the 'The Clinical Decision Making in Nursing Scale'. Of the respondents in this study, 45% of the students were second class, 30.6% of the students were third class and 24.3% of the students were fourth class. There was a statistically significant positive correlation found between the clinical learning environment and the nursing students' academic motivation (r=0.182, pdecision making (r=0.082, p>.05). One of the prerequisites for the training of qualified students is to provide nursing students with a qualified clinical environment. It was found that nursing students' academic motivation increased as the quality of their clinical learning environment improved. Copyright © 2015 Elsevier Ltd. All rights reserved.

    The persistence of academic difficulties from childhood through adulthood has led researchers to focus on the identification of the early factors influencing children's subsequent achievement in order to improve the efficient screening of children who might be at risk of school failure. The foundations of academic achievement can be accurately traced back to the preschool years prior to children's entry in formal schooling and are largely influenced by environmental determinants. Importantly, some environmental conditions act as early risk factors undermining children's later academic achievement due to the well-established relation between underachievement and exposure to moderate to high levels of environmental risk. In the present study, we aimed to investigate the longitudinal effects of environment-level factors (sociodemographic and family characteristics) and early risk exposure at kindergarten on children's subsequent academic achievement at the end of middle school (grade 9). The sample of analysis comprised 654 kindergarteners aged 5-6 years (2001-2002 school year) followed through the end of middle school when they were aged 14-15 years (2010-2011 school year). At kindergarten, assessment included questionnaire-based measures of sociodemographic and family background characteristics. These included an original set of information pertaining to family background including parental nationality, education level, history of reading difficulties, type of early childcare, family situation, family size, and language-based bedtime routines, as well as individual-level factors such as children's first language, medical history, language delay, birth weight, age of walking onset, and gestation period. At grade 9, outcome measures were composed of children's results in the national evaluations performed at the end of middle school ("Diplôme National du Brevet"), or history of repetition for a second year of the same class. The results indicated that all family

    Full Text Available Introduction: The purpose of this cross sectional study is to gain insight into the students and clinical instructors’ perception of learning environments at Yazd medical University in 2012. Various aspects of environment are compared between courses, gender and age. Students and instructors’ perspectives are reported. Methods: The sample consisted of 158 undergraduate students in their final year of graduation in the nursing, anesthesia, operating room, laboratory, radiology, midwifery courses and their 20 clinical instructors at Yazd University. Data were obtained using the Dundee Ready Education Environment Measure (DREEM. Scores were compared across grouping variables identified via demographic information. Results: Scores were fairly high for both students and clinical instructors (M=110.0; SD=21.2 and M=93.1; SD=10.3 respectively, indicating an overall positive perception of learning environments between both groups. The perception of atmosphere subscale (PA received the highest mean grade by both groups. Total DREEM scores didn’t vary significantly between courses (p>0.05 but the results of ANOVA test showed significant differences only for perception of teaching and perception of atmosphere domains. There was not a significant association between females and males regarding total DREEM score (p>0.05. Conclusions: The more positive than negative perception held by the Yazd University health science students and instructors is hopefully indicative of a favorable teaching-learning environment. Overall; teachers’ attention to principles of educational design and setting a favorable environment to promote better learning is recommended.

Completed phase III RCTs evaluating new drugs in common cancers between January 2005 and October 2016 were identified from ClinicalTrials.gov. Lay media reporting was identified by searching LexisNexis Academic. Scientific reporting was defined as presentation at an academic conference or publication in full. Associations between reporting in the lay media before scientific reporting and study design and sponsorship were evaluated using logistic regression. Of 180 RCTs identified, 52% were reported in the lay media and in 27%, lay media reporting occurred before scientific reporting with an increasing trend over time (p = 0.009). Reporting in the lay media before scientific reporting was associated with positive results (OR: 2.10, p = 0.04), targeted therapy compared to chemotherapy (OR: 4.75, p = 0.006), immunotherapy compared to chemotherapy (OR: 7.60, p = 0.02), and prostate cancer compared to breast cancer (OR: 3.25, p = 0.02). Over a quarter of all RCTs in common cancers are reported in the lay media before they are reported scientifically with an increasing proportion over time. Positive trials, studies in prostate cancer, and trials of immunotherapy are associated with early reporting in the lay media. © 2017 S. Karger AG, Basel.

    Uncertainty remains concerning how children's reading and academic self-concept are related and how these are differentially affected by social disadvantage and home learning environments. To contrast the impacts of early socio-economic risks and preschool home learning environments upon British children's reading abilities and academic self-concept between 7 and 10 years. n = 3,172 British children aged 3-10 years and their families. A secondary analysis of the nationally representative UK EPPE database. Multilevel structural equation modelling calculated the direct, indirect, and total impacts of early socio-economic risks (0-3 years) and preschool home learning environments (3-5 years) upon children's reading ability and academic self-concept between 7 and 10 years. Early socio-economic risk had different effects upon children's reading ability and academic self-concept. Early socio-economic risks affected children's reading at ages 7 and 10 both directly and indirectly via effects upon preschool home learning environments. By contrast, early socio-economic risks had only indirect effects upon children's academic self-concept via less stimulating home learning environments in the preschool period and by limiting reading abilities early on in primary school. Although the impacts of early socio-economic risks are larger and more easily observed upon reading than upon academic self-concept, they can impact both by making it less likely that children will experience enriching home learning environments during the preschool period. This has implications for social policymakers, early educators, and interventionists. Intervening early and improving preschool home learning environments can do more than raise children's reading abilities; secondary benefits may also be achievable upon children's self-concept. © 2017 The British Psychological Society.

    2018-06-01

    Adding value in a university-based academic health care system provides unique challenges when compared to other health care delivery models. Herein, we describe our experience in adding value to joint arthroplasty care at the University of Utah, where the concept of value-based health care reform has become an embraced and driving force. To improve the value, new resources were needed for care redesign, physician leadership, and engagement in alternative payment models. The changes that occurred at our institution are described. Real-time data and knowledgeable personnel working behind the scenes, while physicians provide clinical care, help move clinical pathway redesigns. Engaged physicians are essential to the successful implementation of value creation and care pathway redesign that can lead to improvements in value. An investment of money and resources toward added infrastructure and personnel is often needed to realize large-scale improvements. Alignment of providers, payers, and hospital administration, including by means of gainsharing programs, can lead to improvements. Although significant care pathway redesign efforts may realize substantial initial cost savings, savings may be asymptotic in nature, which calls into question the likely sustainability of programs that incentivize or penalize payments based on historical targets.

    The purpose of this research study was to examine, for undergraduate women of various Asian American ethnic backgrounds, the influence of background contextual and college environment factors on their sense of academic self-efficacy and achievement in science, technology, engineering, and mathematics (STEM) majors. Social cognitive career theory and its critiques provided a theoretical foundation for relationships from past performance, socioeconomic status, acculturation, and college environment variables (compositional diversity, racial climate, gendered climate, academic peer support), to academic self-efficacy and achievement. Data were collected through an online survey. Instrumentation included the scales of Language, Identity, and Behavioral Acculturation; Gender Discrimination; Faculty and Classroom Behavior; Interactions with Peers; and Academic Milestones Self-efficacy. The participants were 228 Asian American undergraduate women in STEM at a large public, doctoral research extensive university on the east coast; the response rate was 51%. In three MANOVAs for nine social cognitive career variables, four ethnic groups (East, South, Southeast, and Multi-ethnic Asian American) significantly differed only on socioeconomic status. In path analysis, the initial model was not a good fit and was rejected. The model was respecified through statistical and theoretical evaluation, tested in exploratory analysis, and considered a good fit. The respecified model explained 36% of semester GPA (achievement) and 28% of academic self-efficacy. The academic achievement of Asian American women in STEM was related to past performance, background contextual factors, academic self-efficacy, academic peer support, and gendered climate. The strongest direct influence on achievement was academic self-efficacy followed by past performance. The total effect of Asian acculturation on achievement was negative and the total effect of American acculturation on achievement was not

    Alotaibi, Khaled N

    2016-01-01

    There has been some ground-breaking research on self-directed learning (SDL) in nursing education which reveals the superiority of SDL to traditional learning methods in terms of students' academic performance and the development of positive attitudes toward the learning process on the part of both students and teachers. The relationship between students' self-directed learning readiness (SDLR) and students' academic performance, and the mediating role of students' perceptions of the learning environment needs further investigation. In this study, it is proposed that students' perceptions of their learning environment could enhance their SDLR and thus boost their academic performance (in terms of their GPA). A descriptive design was used to examine the relationships between the domains of SDLR, which are self-management, desire to learn and self-control and students' perceptions of the learning environment (SPLE) and students' GPA. A survey involving 342 [Corrected] Saudi students from nursing and emergency medical services undergraduate programs in King Saud University was used for this research. The results showed that SDLR level positively influenced students' academic performance positively, and that students' perceptions of their learning environment played a significant role in determining their level of SDLR and academic performance. It is recommended that nursing and emergency medical services educators provide a supportive learning environment in terms of good teaching, clear goals and standards, appropriate assessment, appropriate workload, and emphasis on independence to encourage students to engage in the process of SDL which can, in turn, enhance their academic performance.

    Full Text Available Thousands of young researchers come from different parts of the world every year to take up postdoctoral (postdoc research fellowship positions in the developed countries. In the US alone, there were 48,601 postdocs in the year 2005 working in different labs in the fields of science, health and engineering. Many pursue this option for lack of other alternatives. Expectedly, these individuals face a lot of difficulties in making this transition from being a student to becoming an employee of an institution. Many institutions are prepared to make this transition and period of stay easy for their fellows while others are not equipped at all. The presence of a postdoc office (established by an institution or an association (formed by the fellows can be of immense help to postdocs. Additionally, the availability of institutional professional development and leadership programs can also help to nurture and polish postdoc fellows into future faculty members and valuable members of the community at large. To name a few, these professional development programs can focus on communication and presentation skills, medical education, teaching and learning, bioethics and mentorship. There is an urgent need to address some or all of these issues so that better training environment and opportunities are available to this group of postdoc fellows.

    2006-01-01

    Using the data from the French Environment Barometer EDF-RD 2004 (national representative sample of French citizens aged over 15) and surveys by ADEME between 2000 and 2005, the paper investigates lay perceptions of the causes and consequences of the greenhouse effect, which may be considered as archetypical of contemporary environmental risks. Beyond lay lack of knowledge, the greenhouse effect gives rise to coherent and meaningful cognitions, including causal explanations, shaped by the pre-existing cognitive framework. This cognitive work, based on analogic rather than scientific thought, strings together the greenhouse effect, ozone depletion, air pollution and even nuclear power. The cognitive process is also fed by the individuals' general conceptions of Nature and of the rights and duties of humankind towards Nature. People are not greatly worried about the unseen and controversial consequences of the greenhouse effect: such worry could be one of those 'elite fears' mentioned by Beck. Finally, while the efficiency of public policies to counter the greenhouse effect requires extensive societal involvement, low confidence towards both political and scientific authorities may prevent the population from becoming aware of the environmental stakes tied to the greenhouse effect.

    Lay consultations can facilitate or impede healthcare. However, little is known about how lay consultations for symptom evaluation affect treatment decision-making. The purpose of this study was to explore the role of lay consultations in symptom evaluation prior to hospitalization among patients with heart failure. Semi-structured interviews were conducted with 60 patients hospitalized for acute decompensated heart failure. Chi-square and Fisher's exact tests, along with logistic regression were used to characterize lay consultations in this sample. A large proportion of patients engaged in lay consultations for symptom evaluation and decision-making before hospitalization. Lay consultants provided attributions and advice and helped make the decision to seek medical care. Men consulted more often with their spouse than women, while women more often consulted with adult children. Findings have implications for optimizing heart failure self-management interventions, improving outcomes, and reducing hospital readmissions.

  11. The supplemental instruction program: Student perceptions of the learning environment and impact on student academic achievement in college science at California State University, San Marcos

    Hizer, Suzanne Elizabeth

    Higher education in science has been criticized and calls to increase student learning and persistence to degree has been recognized as a national problem by the Department of Education, the National Science Foundation, the National Research Council, and the National Academy of Sciences. One mode of academic assistance that may directly address this issue is the implementation of Supplemental Instruction (SI) in science courses. SI is a specific model of academic assistance designed to help students in historically difficult science classes master course content, thus increasing their academic achievement and retention. This study assessed the SI program at California State University, San Marcos, in supported science courses. Specifically, academic achievement based on final course grades were compared between SI participating and nonparticipating students, multiple affective factors were measured at the beginning and end of the semester, and students' perceptions of the classroom and SI session learning environments recorded. Overall, students who attended five or more SI sessions achieved higher final course grades. Students who chose to participate in SI had higher initial levels of responsibility and anxiety. Additionally, SI participants experienced a reduction in anxiety over the semester whereas nonparticipants experienced an increase in anxiety from beginning to the end of the semester. The learning environment of SI embodies higher levels of constructivist principles of active learning such as cooperation, cohesiveness, innovation, and personalization---with one exception for the physics course, which is a based on problem-based learning. Structural equation modeling of variables indicates that high self-efficacy at the end of the semester is directly related to high final course grades; this is mediated by cohesion in the classroom and the cooperation evidenced in SI sessions. These findings are elaborated by student descriptions of what happened in SI

A control diet based on corn – soybean meal was formulated to meet nutrient requirement of ISA Brown laying hens. Two treatments, the control diet (C and C + 1000 g Avizyme/tonne diet were tested. Each diet was fed to 80 birds (20 replicates of 4 birds from 20 to 72 weeks of age, and performances of birds (feed intake, egg production, egg size, egg mass, feed conversion ratio, and egg quality were measured. All data were subject to analyses of variance following the t-test. Results showed that the addition of Avizyme 1500 to the feed reduced feed intake by 4% (P < 0.01, mortality by 75 % or from 15% to 3.75% (P < 0.01 and improved the feed conversion ratio by 3 % (P < 0.05. The high mortality of the control treatment (15% is explained by an E.coli infection that was observed following the post-mortem examination of dead birds. The egg production (HD and HH, egg size and egg mass however were not significantly affected by the Avizyme supplementation. Egg quality (HU, yolk colour score, yolk weight and shell thickness was not significantly affected by Avizyme supplementation. It can be concluded that the supplementation of 1000 g Avizyme /tonne of diet improved feed efficiency and this was mediated via a reduction in feed intake.

    2014-06-01

    For the past decade, and expected for the next decade, Australia faces a significant health workforce shortage and an acute maldistribution of health workforce. Against this background the governments at both national and state level have been increasing the training places for all health practitioners and trying to redress the imbalance through a strong regional focus on these developments. Dentistry has been an active participant in these workforce initiatives. This study examines the increasing demand for academics and discusses the existing pathways for increase, and also examines in detail the advantages of a sustainable, shared-model approach, using dentistry as a model for other disciplines. Three non-exclusive pathways for reform are considered: importation of academics, delayed retirement and the shared resource approach. Of the various solutions outlined in this review a detailed explanation of a cost-effective shared model of senior academic leadership is highlighted as a viable, sustainable model for ameliorating the shortage.

    Full Text Available Education is a learnt behaviour, which shapes and moulds the nature of a human being by transforming him/her into a human resource and helps in social progress. Children start learning in the lap of their parents. They are bought up by accumulating the knowledge gained from the interaction with the family members. This interaction varies from one family to another. Even when they start going to an institution for the formal education, home environment leaves an influence on his/her attitude towards education. In addition to institutional influence, proper understanding of the impact of home environment is essential for taking due care in development of human resource. Backwardness of the female students in different hierarchies of the educational sector is a major concern in India as well as in West Bengal since a very long period. In spite of ample efforts to increase the rate of enrolment and to develop the quality of education in both national and state level, the progress in terms of actual involvement in educational activities is not up to the mark in many cases. In the light of this background, a grass-root level study has been conducted to understand the role of home environment on determining the academic involvement of the female students belonging to different hierarchies of tribe-caste continuum in a rural context of Bankura District, West Bengal. It aims to identify the major components of home environment, which determine the level of cohort specific academic involvement in the type of families from different social background. In order to retrieve various perspectives on their home environment, we surveyed female students reading in VIII —XII and belonging to the age group 13 to 18 years. From the micro level analysis, it has been found that caste and tribal identity based disparity as well as family type wise differences in level of academic involvement (LAI is profound in the study area.

    Full Text Available Introduction. In the conditions of the modern globalization, one of the most significant indicators of competitiveness of the universities is the academic mobility of students, graduate students, teachers and research associates that implies their free and competent enough foreign language skills, first of all English. Yet, until recently, comparatively little attention has been paid to foreign language skills of the Russian academic teaching staff. However, in recent years, with regard to the process acceleration of internationalization of the higher education to provide own effective functioning and remain a demanded one in education and training market, domestic higher education institutions are forced to quickly fill in the gaps of foreign language knowledge among academic teaching staff. The aim of this article is to analyse and describe the tuition outcomes for academic teaching staff based on the official exam results from Cambridge English Language Assessment for three years (2015–2017. Methodology and research methods. The research, which is grounded in interdisciplinary approach and lies at the intersection of psychology, linguistics and pedagogics, was conducted on the basis of the statistical analysis and generalization of mean scores of English language testing results, taking into account qualitative and quantitative standards of speech skills: reading, writing, listening, speaking and use of English (for levels B2, C1.

    The aim of this paper was to investigate the effect of heat stress on the regulation of appetite-associated genes in laying hens. Forty eight laying hens were randomly divided into two circumstances: high (31 ± 1.5°C; relative humidity, 82.0 ± 2.2%) or normal (20 ± 2°C, control; relative humidity, 60.1 ± 4.5%) ambient environment. Heat stress decreased body weight gain (P feed intake (P feed efficiency (P feed intake in laying hens under high ambient temperature.

    Recent reports suggest that the Government of India is favourably inclined to change policy and enable establishments employing less than 1,000 workers to lay-off employees and undertake retrenchments or closures without prior permission. Corporate lay-offs in the U.S. indicate an ever-increasing trend and do not make a comforting reading. The year 2001 for example, saw the highest number of job cuts in the Fortune 500 companies than in any year ever since the survey of lay-offs were launched...

    Full Text Available The purpose of this study was to investigate the welfare of laying hens Moravia SSL housed in small-scale hen house with free range, behavior, egg production and selected physical indicators of eggs and chemical indicators of egg mass. The laying hens were kept in a hen house on deep litter. Breeding facility of hen house was within the meaning of recommendation for applying the principles of welfare, i.e. the space and breeding facility within the meaning of enriched breeding environment. Stocking density of the laying hens corresponded with recommendations for unrestricted movement and implementing natural activities. The hen house was equipped with the perch, nest, feeder and drinker. The commercial feed mixture was used for feeding, which is intended for laying hens. The kitchen remains were added to feed mixture, as are wet bread, the non-edible remains of foodstuffs. A feed mixture was served to laying hens 825 g per day. The laying hens had free access to drinking water, grazing, ground pecking, ground scratching and dust-bathing and in the free range. We focused investigation of on the egg laying intensity, selected parameters of physical egg quality and chemical egg contents. Time to relax of laying hens was adjusted according to the summer and winter breeding seasons. The main activities of free-range hens are grazing, ground pecking, ground scratching and dust-bathing. The main activities of free-range hens are grazing, ground pecking, ground scratching and dust-bathing. These activities were investigated in laying hens too in dependent of year period, more in the summer. Housing of the hens was equipped with the perch. The laying hens regularly used a perch. A beginning of occupation the perch was at the time of time growing dark, at the end of the light day. A nesting material was selected regular, monthly exchange.

    Today, EDF plants face a new release permit after a steam generators (SGs) wet lay-up, so that the legal authorizations for wastes release to the environment, renewed or being renewed by the safety authorities, allow smallest quantities of wastes than earlier. In this context, EDF studies the optimization of SGs lay-up conditions, and especially of the hydrazine concentration, in order to reduce the liquid wastes releases to the environment, while keeping low corrosion conditions. At the same time, EDF examines a treatment for hydrazine elimination in liquid wastes before their releases. An experimental study has been conducted in order to evaluate the efficiency of hydrazine to control materials corrosion and of nitrogen gas phase to deaerate water. The consequences of lay-up conditions on carbon steel corrosion has also been studied. In the absence of an efficient alternative reagent, hydrazine remains necessary but implies a great care due to its carcinogenic risks and to its toxicity for aquatic organisms. This choice implies studying a method for hydrazine elimination before its release to the environment. The hydrazine elimination from SGs lay-up wastes could be achieved within about one day, by adding about 700 to 800 liters of 30% hydrogen peroxide solution to eliminate 100 kg hydrazine. Copper sulfate would have to be added if copper is not present in the wastes; the copper content in the wastes should be around 100 to 200 μg/kg for the reaction to be fast enough, which is consistent with the legal authorization for copper release to the environment. The nuclear power plants would have to adjust the quantity of hydrogen peroxide to add to the wastes to be treated, based on the quantity of hydrazine to eliminate, in order to avoid any excess of hydrogen peroxide in the wastes at the end of the treatment, since this species is not allowed to be released to the environment. Moreover, the hydrogen peroxide treatment should not have any significant impact on

    Full Text Available The international assessment studies of key competences, such as the PISA report of the OECD, have revealed that the academic performance of Spanish students is significantly below the OECD average; in addition, it has also been confirmed that the results of immigrant students are consistently lower than those of their native counterparts. Given the context, the first objective of this work is to observe the variables (support, control, school satisfaction and learning environment which distinguish between native and immigrant students with high and low academic performance; the second objective is to check, by comparing the native and immigrant students with high and low performance and separating the two levels, to find out which of the selected variables clearly differentiate the two groups. To this end, a sample of 1359 students was used (79.8% native students and 20.2% immigrant students of Latin American origin, who were enrolled in the 5th and 6th year of Primary Education (aged 10-11 years and in the 1st and 2nd year of Secondary Education (aged 12-13 years. The origin and the fact of being a retained student or not were estimated as independent variables, whereas their responses to the variables of perceived family support and control (paternal and maternal separately, their school satisfaction and assessment of the learning environment were taken into account as dependent variables. Considering that the reliability of the scales used is adequate, along with the optimal factorization in a series of coherent constructs, it was revealed that the main differences consisted of individual dimensions (perception of family support and control and, to a lesser extent, of dimensions related to the context (assessment of the school and learning environments. Given the results obtained, our intention is to provide solid evidence that would facilitate the design of family involvement programs, helping to improve students' educational performance.

  5. We Are Going to Name Names and Call You Out! Improving the Team in the Academic Operating Room Environment.

    2017-05-01

    Communication failures between multidisciplinary teams can impact efficiency, performance, and morale. Academic operating rooms (ORs) often have surgical, anesthesia, and nursing teams, each teaching multiple trainees. Incorrectly identifying name and "rank" (postgraduate year [PGY]) of resident trainees can disrupt performance evaluations and team morale and even potentially impair delivery of quality care when miscommunication errors proliferate. Our OR-based survey asked 50 participants (18 surgeons, 14 anesthesiologists, and 18 nursing members), to recall basic identification data including provider names and PGY levels from their recent collaborating OR teams. Participants also weighed in on the importance of using accurate "names and ranks" for all OR participants. Each service reliably knew their own team members' names and rank. However, surgery and anesthesia teams displayed decreased knowledge about their lower level trainees, whereas nursing teams performed best, identifying all level nurses present. Deficits occurred whenever participants tried recalling basic identifying data about contributors from any other collaborating team. Typically, misidentified participants were lower level PGY residents working on other teams' services. All survey respondents desired improving systems to better remember "names and ranks" identifications among OR participants, citing both safety and team morale benefits. Many fail to know the names and ranks of contributors among members of different OR teams. Even our most reliable nursing team was inconsistent at identification information from collaborating practitioners. Despite universally acknowledged benefits, participants rarely learned basic background identification data beyond their own team. Those surveyed all desired improving identifications with suggestions including sterile name and rank tags and proper notification of entry and exit from the OR. Because successful collaborations require appropriate level task

  9. What are lay theories of social class?

    Science.gov (United States)

    Varnum, Michael E W

    2013-01-01

    Numerous studies have documented the effects of social class on psychological and behavioral variables. However, lay beliefs about how social class affects these dimensions have not been systematically tested. Studies 1 and 2 assessed lay beliefs about the association between social class and 8 variables (including psychological and behavioral tendencies and cognitive ability). Study 3 assessed lay beliefs about the Big five personality traits and social class, and study 4 reframed the 8 variables from study 1 in opposite terms and yielded similar results. Study 5 contained the variables framed as in both studies 1 and 4, and replicated those results suggesting that framing effects were not responsible for the effects observed. Interestingly, for the most part lay beliefs about social class did not differ as a function of participants' own social class. In general people held relatively accurate and consistent stereotypes about the relationship between social class and well-being, health, intelligence, and neuroticism. In contrast lay beliefs regarding social class and reasoning styles, as well as relational, social, and emotional tendencies were less consistent and coherent. This work suggests that on the whole people's beliefs about social class are not particularly accurate, and further that in some domains there are contradictory stereotypes about the consequences of social class.

    2004-01-01

    Use of digital medical images has become common over the last several years, coincident with the release of inexpensive, mega-pixel quality digital cameras and the transition to digital radiology operation by hospitals. One problem that clinicians, medical educators, and basic scientists encounter when handling images is the difficulty of using business and graphic arts commercial-off-the-shelf (COTS) software in multicontext authoring and interactive teaching environments. The authors investigated and developed software-supported methodologies to help clinicians, medical educators, and basic scientists become more efficient and effective in their digital imaging environments. The software that the authors developed provides the ability to annotate images based on a multispecialty methodology for annotation and visual knowledge representation. This annotation methodology is designed by consensus, with contributions from the authors and physicians, medical educators, and basic scientists in the Departments of Radiology, Neurobiology and Anatomy, Dermatology, and Ophthalmology at the University of Utah. The annotation methodology functions as a foundation for creating, using, reusing, and extending dynamic annotations in a context-appropriate, interactive digital environment. The annotation methodology supports the authoring process as well as output and presentation mechanisms. The annotation methodology is the foundation for a Windows implementation that allows annotated elements to be represented as structured eXtensible Markup Language and stored separate from the image(s).

  14. Building an open academic environment - a new approach to empowering students in their learning of anatomy through 'Shadow Modules'.

    Scott, Jonathan L; Moxham, Bernard J; Rutherford, Stephen M

    2014-03-01

    Teaching and learning in anatomy is undertaken by a variety of methodologies, yet all of these pedagogies benefit from students discussing and reflecting upon their learning activities. An approach of particular potency is peer-mediated learning, through either peer-teaching or collaborative peer-learning. Collaborative, peer-mediated, learning activities help promote deep learning approaches and foster communities of practice in learning. Students generally flourish in collaborative learning settings but there are limitations to the benefits of collaborative learning undertaken solely within the confines of modular curricula. We describe the development of peer-mediated learning through student-focused and student-led study groups we have termed 'Shadow Modules'. The 'Shadow Module' takes place parallel to the formal academically taught module and facilitates collaboration between students to support their learning for that module. In 'Shadow Module' activities, students collaborate towards curating existing online open resources as well as developing learning resources of their own to support their study. Through the use of communication technologies and Web 2.0 tools these resources are able to be shared with their peers, thus enhancing the learning experience of all students following the module. The Shadow Module activities have the potential to lead to participants feeling a greater sense of engagement with the subject material, as well as improving their study and group-working skills and developing digital literacy. The outputs from Shadow Module collaborative work are open-source and may be utilised by subsequent student cohorts, thus building up a repository of learning resources designed by and for students. Shadow Module activities would benefit all pedagogies in the study of anatomy, and support students moving from being passive consumers to active participants in learning. © 2013 Anatomical Society.

    2013-06-01

    Full Text Available Since thermal environment affects production, egg quality and laying hens’ mortality rates, it is highly relevant to control the thermal environment within poultry houses so that the best financial profits could be obtained. Three commercial poultry houses with different climatization systems are analyzed in current research: a poultry house with tunnel-like ventilation and pad cooling; a poultry house with natural ventilation and nebulization; a poultry house with simple natural ventilation. Their thermal environment, production, egg quality and laying hens’ mortality rates among different poultry houses and at different areas of the same poultry house are compared. Economic profits based on difference in electric energy consumption by climatization systems and on the laying hens’ productivity of each poultry house are calculated. Electricity meters were installed within the electrical circuits of the climatization and light systems of the three poultry houses. Data were registered between December 2011 and March 2012 and results showed that all the poultry houses featured heterogeneity in internal thermal environment with faults in the climatization systems. Important differences were reported in egg production and quality caused by overheating. The poultry house with tunnel-like ventilation and pad cooling had the best thermal isolation from the external environment that resulted in a 12.04% improvement in production, decrease between 30 and 40% in laying hens’ mortality rates and the best economic result.

    Full Text Available The present study was based on the examination of the natural egg laying habits of domestic geese. The authors studied Grey Landes geese during the summer laying period. On the day of arrival of the birds a TyniTalk II artificial egg was placed in each nest. These eggs contain a microchip which detects and records data on the temperature of the surroundings. The results obtained demonstrate that after laying a certain number of eggs females laying under natural conditions sit on the nest not only when laying new eggs, but also to warm the eggs in it. The time devoted to warming increases with the laying period.

  20. Control room lay-out

    2004-01-01

    TRIUMF (Tri-University Meson Facility) is Canada's national laboratory for particle and nuclear physics. There are 6 accelerators and 3 Control Rooms at TRIUMF. The main control room serves the big cyclotron, the 500 MeV, and the adjacent experiment. The 42 MeV and two 32 MeV ones are production dedicated. These cyclotrons belong to a private company but are operated by TRIUMF staff from ATG (Applied Technology Group) Control Room. The last is ISAC (Isotope Acceleration and Separation) Control Room, from which the LINAC is controlled. Research areas cover theoretical (2 subjects), pure (5 subjects) and applied (8 subjects) physics. In the early '70s, as the 500 MeV was being completed, the first Control Room was built in the main accelerator building. The recent topics covered by this paper are proton and pion therapy, what are the operator's duties?, the CP42, TR30 and TR13 cyclotron control rooms, the ISAC control systems including control room modification. Due to the nature of an operator's job, the Control Room layout is pretty important. This is true for any work environment, but when working shifts it becomes essential. Lots of time and effort, not to mention money, were spent to figure out the optimum configuration. It seems to me that the key factor in the control room layout is versatility, and this is because it has to keep happy a group of people with different inclinations, which have a tendency to become quite moody after the second night shift. No matter what, there will still be unhappy people, but we are trying our best. (Y. Tanaka)

    2013-01-01

    This study examined lay theories regarding gender identity disorder (GID). Pilot interviews were completed with participants (n = 10) regarding their views on possible causes and treatments of GID. Participants (mainly young British people and students; n = 124) then completed a questionnaire that was based on the interviews and a review of the salient literature on lay theories. As hypothesized, participants believed most in biomedical causes and treatments of GID. Factor analysis (with varimax rotation) identified 4 factors in relation to causes of GID: upbringing and personal factors, pregnancy and brain abnormalities, environmental factors, and biomedical causes. Five factors that were identified in relation to the cure/treatment of GID were psychological assistance and personal factors, extreme medical and behavioral changes, alternative therapies, external factors, and medical treatments. The results indicated that participants neither agreed nor strongly disagreed about causes and cures regarding GID, but that these beliefs were logically related. Limitations, particularly of sampling, were considered.

    2005-01-01

    As in many other areas, there is a divide between lay and expert perceptions of risk within the food sector, and this can lead to disagreement over priorities in food risk management. The risk perception literature tends to stress that the parties involved in this disagreement have different...... concepts of risk and hence are bound more or less to talk at cross-purposes. This paper suggests an alternative analysis: In the light of moral theory, the conflicting perspectives can be understood as a genuine moral conflict. When this conflict is conceptualised, a rational dialogue becomes possible....... The paper reports a series of qualitative interviews with lay people and experts on zoonotic food risks. The interviews are used to reconstruct the values underlying some of the dominant perspectives. The conflict between these stylised perspectives is then analysed with the help of moral theory.

    Full Text Available From 2007–2008, data on animal health and welfare and farm management during rearing and laying periods were collected from 49 flocks of organic laying hens in the Netherlands. Our aim was to investigate how organic egg farms performed in terms of animal health and welfare and which farm factors affected this performance. The flocks in our study were kept on farms with 34 to 25,000 hens (average 9,300 hens. Seventy-one percent of the flocks consisted of ‘silver hybrids’: white hens that lay brown eggs. Fifty-five percent of the flocks were kept in floor-based housing and 45% of the flocks in aviaries. No relation was found between the amount of time spent outdoors during the laying period and mortality at 60 weeks. Flocks that used their outdoor run more intensively had better feather scores. In 40% of the flocks there was mortality caused by predators. The average feed intake was 129 g/day at 30 weeks and 133 g/day at 60 weeks of age. The average percentage of mislaid eggs decreased from three at 30 weeks to two at 60 weeks. The average mortality was 7.8% at 60 weeks. Twenty-five percent of the flocks were not treated for worms in their first 50 weeks. Flubenol© was applied to the flocks that were treated. Ten percent of the flocks followed Flubenol© instructions for use and were wormed five or more times. The other 65% percent were treated irregularly between one and four times. Sixty-eight percent of the flocks showed little or no feather damage, 24% showed moderate damage and 8% showed severe damage. The feather score was better if the hens used the free-range area more intensely, the laying percentage at 60 weeks was higher, and if they were allowed to go outside sooner after arrival on the laying farm. In 69% of the flocks, hens had peck wounds in the vent area: on average this was 18% of the hens. Keel bone deformations were found in all flocks, on average in 21% of the birds. In 78% of the flocks, an average of 13% of the hens

    The international assessment studies of key competences, such as the PISA report of the OECD, have revealed that the academic performance of Spanish students is significantly below the OECD average. In addition, it has also been confirmed that the results of immigrant students are consistently lower than those of their native counterparts. Given the context, the first objective of this work is to observe the variables (support, control, school satisfaction, and learning environment) which distinguish between retained and non-retained native and immigrant students. The second objective is to check, by comparing the retained and non-retained native and immigrant students and separating the two levels, in order to find out which of the selected variables clearly differentiate the two groups. A sample of 1359 students was used (79.8% native students and 20.2% immigrant students of Latin American origin), who were enrolled in the 5th and 6th year of Primary Education (aged 10-11 years) and in the 1st and 2nd year of Secondary Education (aged 12-13 years). The measurement scales, which undergo a psychometric analysis in the current work, have been developed in a previous research study (Lorenzo et al., 2009). The construct validity and reliability are reported (obtaining alpha indices between 0.705 and 0.787). Subsequently, and depending on the results of this analysis, inferential analyses are performed, using as independent variables the ethno-cultural origin and being retained or not, whereas, as dependent variables, the indices referring to students' perception of family support and control, as well as the assessment of the school and learning environment. Among other results, the Group × Being retained/Not being retained [ F (1, 1315) = 4.67, p family support. Given the results obtained, our intention is to provide solid evidence that would facilitate the design of family involvement programs, helping to improve students' educational performance.

  13. Chlorinated drinking water for lightweight laying hens

    A.F. Schneider

    Full Text Available ABSTRACT The study aimed to evaluate the effect of different levels of chlorine in drinking water of laying hens on zootechnical performance, eggs shell quality, hemogasometry levels and calcium content in tibia. 144 Hy-Line laying hens, 61 weeks old, were used distributed in 24 metabolism cages. They were subjected to water diets, for a period of 28 days, using sodium hypochlorite as a chlorine source in order to obtain the following concentrations: 5ppm (control, 20ppm, 50ppm, and 100ppm. Their performance was evaluated through water consumption, feed intake, egg production and weight, egg mass, feed conversion. Shell quality was measured by specific gravity. At the end of the experiment, arterial blood was collected for blood gas level assessment and a poultry of each replicate was sacrificed to obtain tibia and calcium content measurement. There was a water consumption reduction from 20ppm of chlorine and feed intake reduction in poultry receiving water with 100ppm of chlorine. The regression analysis showed that the higher the level of chlorine in water, the higher the reduction in consumption. There were no differences in egg production and weight, egg mass, feed conversion, specific gravity, tibia calcium content, and hemogasometry levels (hydrogenionic potential, carbon dioxide partial pressure, oxygen partial pressure, sodium, potassium, chloride, bicarbonate, carbon dioxide total concentration, anion gap and oxygen saturation. The use of levels above 5ppm of chlorine is not recommended in the water of lightweight laying hens.

    Full Text Available A research was conducted to investigate the effects of vaccination protocols for Infectious Bronchitis (IB on egg production, egg quality, and IB antibody titres of laying hens. Different initial vaccination (Control, VicS eye, VicS spray, VicS water, A3 eye, A3 spray, and A3 water for IB were administered to day-old Isa Brown hens. Half the hens were revaccinated regularly during lay whereas the other hens were not vaccinated. Results showed that initial vaccination treatment had significant effects on hen day egg production and egg quality of egg weight, shell reflectivity, shell breaking strength, shell thickness, albumen height, Haugh Units, and IB antibody titre levels, but had no effect on percentage of shell and yolk colour. Egg weight and shell reflectivity were less favourable in the control hens. In contrast, shell breaking strength and shell thickness were highest for the group that initially received A3 vaccine in water. However, regular revaccination had some deleterious effects on egg production and egg quality. There were no significant effects of revaccination on IB antibody titres. It is concluded that there was little advantage in regularly revaccinating laying hens for IB virus, since they had received appropriate initial vaccination.

    The development of the hydrocarbon resources of the North Sea has resulted in both offshore and onshore environmental repercussions, involving the existing physical attributes of the sea and seabed, the coastline and adjoining land. The social and economic repercussions of the industry were equally widespread. The dramatic and speedy impact of the exploration and exploitation of the northern North Sea resources in the early 1970s, on the physical resources of Scotland was quickly realised together with the concern that any environmental and social damage to the physical and social fabric should be kept to a minimum. To this end, a wide range of research and other activities by central and local government, and other interested agencies was undertaken to extend existing knowledge on the marine and terrestrial environments that might be affected by the oil and gas industry. The outcome of these activities is summarized in this paper. The topics covered include a survey of the marine ecosystems of the North Sea, the fishing industry, the impact of oil pollution on seabirds and fish stocks, the ecology of the Scottish coastline and the impact of the petroleum industry on a selection of particular sites.

  1. Review of rearing-related factors affecting the welfare of laying hens

    Science.gov (United States)

    Janczak, Andrew M.; Riber, Anja B.

    2015-01-01

    Laying hens may face a number of welfare problems including: acute and chronic pain caused by beak trimming; exaggerated fearfulness that may cause stress and suffocation; difficulties in locating resources, resulting potentially in emaciation and dehydration; frustration and boredom, caused by an environment that is barren; feather pecking; cannibalism; foot lesions; and bone fractures. In Europe, a greater proportion of laying hens are housed in non-cage systems compared to the rest of the world. The extent of the different welfare problems may therefore vary between countries as the type of housing system influences the risk of suffering. More generally, many of these welfare problems are influenced by the rearing environment of the pullets. This article therefore focuses on welfare problems in laying hens that can be traced back to rearing. Factors that have been studied in relation to their effects on bird welfare include beak trimming, housing type, furnishing, enrichment, feeding, stocking density, flock size, sound and light levels, concentration of gasses, age at transfer from rearing to production facilities, similarity between rearing and production facilities, competence of staff, and interactions between bird strain and environment. The present review aims to summarize rearing-related risk factors of poor welfare in adult laying hens housed according to European Union legislation. It aims to identify gaps in current knowledge, and suggests strategies for improving bird welfare by improving rearing conditions. Two main conclusions of this work are that attempts should be made to use appropriate genetic material and that beak trimming should be limited where possible. In addition to this, the rearing system should provide constant access to appropriate substrates, perches, and mashed feed, and should be as similar as possible to the housing system used for the adult birds. Finally, young birds (pullets) should be moved to the production facilities before

    There are many factors affecting pilots' +Gz-tolerance. Recently, attention of the aviation community has been focused on lay-off and it's impact on +Gz-tolerance. Pilots of the Polish Air Force (PAF) have dealt with that problem for several years now. The aim of the study was to provide insight on how lay-off periods with different duration impact +Gz-tolerance. 95 male jet pilots from the PAF participated in the study. Every one had at least two weeks lay-off period (non-medical reasons). Subjects were divided into four groups according to the length of lay-off period (2-4 weeks; 5-13 weeks; 14-26 weeks; 27-154 weeks), All pilots were subjected to a centrifuge exposure in GOR (0.1 G/s) or ROR (1.0 G/s) profiles, depending on the pre-lay-off exposure. Post-lay-off exposures were carried out directly after lay-off. 18 jet pilots without any lay-off constituted the control group. The difference between pre- and post-lay-off G-tolerance limit (-0,93 +/- 0,53) was statistically significant (p<0.01) only for one group, where lay-off period ranged between two and four weeks. No statistically significant differences were found where influence of other factors like total and yearly flight hours, heart rate gain (AHR) or physical activity measured as maximal oxygen intake were considered. 2-4 weeks of lay-off period decreases +Gz tolerance is statistically significant manner. Subsequent increase of lay-off period does not result in mean tolerance changes for group, however in certain individuals critical decrement of +Gz tolerance occurs. Total and last year flying hours, physical fitness does not modify impact of lay-off period on +Gz tolerance.

    Stressful environments can affect not only egg production and quality but also gene and protein abundance in the ovary and oviduct in laying hens. The oviductal magnum of laying hens is the organ responsible for the synthesis and secretion of egg white proteins. The objective of this study was to investigate the effects of dietary corticosterone as a stress model on the abundance of proteins in the egg white and of mRNA and proteins in the magnum in laying hens. After a 14-day acclimation, 40 laying hens were divided into two groups which were provided for the next 14 days with either control (Control) or corticosterone (Stress) diet containing at 30 mg/kg. Corticosterone treatment resulted in increased feed intake (P ≤ 0.05) and decreased egg production. Two-dimensional electrophoresis (2DE) with MALDI-TOF/TOF MS/MS using eggs obtained on days 0 and 5 revealed differential abundance of egg white proteins by Stress: transiently expressed in neural precursors (TENP), hemopexin (HPX), IgY-Fcυ3-4, and extracellular fatty acid-binding protein (Ex-FABP) were decreased while ovoinhibitor and ovalbumin-related protein X (OVAX) were increased on days 5 vs 0 (P ≤ 0.05). Expression of mRNAs and proteins was also significantly modulated in the magnum of hens in Stress on day 14 (P ≤ 0.05). In conclusion, the current study provides the first evidence showing that dietary corticosterone modulates protein abundance in the egg white in laying hens, and it suggests that environmental stress can differentially modify expression of egg white proteins in laying hens.

  5. Affective cognition: Exploring lay theories of emotion.

    Humans skillfully reason about others' emotions, a phenomenon we term affective cognition. Despite its importance, few formal, quantitative theories have described the mechanisms supporting this phenomenon. We propose that affective cognition involves applying domain-general reasoning processes to domain-specific content knowledge. Observers' knowledge about emotions is represented in rich and coherent lay theories, which comprise consistent relationships between situations, emotions, and behaviors. Observers utilize this knowledge in deciphering social agents' behavior and signals (e.g., facial expressions), in a manner similar to rational inference in other domains. We construct a computational model of a lay theory of emotion, drawing on tools from Bayesian statistics, and test this model across four experiments in which observers drew inferences about others' emotions in a simple gambling paradigm. This work makes two main contributions. First, the model accurately captures observers' flexible but consistent reasoning about the ways that events and others' emotional responses to those events relate to each other. Second, our work models the problem of emotional cue integration-reasoning about others' emotion from multiple emotional cues-as rational inference via Bayes' rule, and we show that this model tightly tracks human observers' empirical judgments. Our results reveal a deep structural relationship between affective cognition and other forms of inference, and suggest wide-ranging applications to basic psychological theory and psychiatry.

    Full Text Available The objective of this study was to evaluate the potassium requirement for laying Japanese quails. Two hundred and forty quails were distributed in a randomized block design, with five treatments and six replicates, with eight birds each. The treatments consisted of a basal diet deficient in potassium (K (2.50 g/kg, supplemented with potassium carbonate, to replace the inert, to reach levels of 2.50, 3.50, 4.50, 5.50 and 6.50 (g/kg of K in the diet. There was a quadratic effect of K levels on feed intake, egg production, egg mass and feed conversion per egg mass and per egg dozen, estimating the requirements of 4.26, 4.41, 4.38, 4.43 and 4.48 (g/kg of K diet, respectively. There was no significant effect on the levels of K in the diet on egg weight, albumen weight, percentage of yolk or shell and yolk color. However, yolk and shell weights reduced and the albumen percentage increased linearly with increasing levels of K in the diet. Despite the reduction of shell weight, the increased levels of K did not influence the specific gravity and shell thickness. The use of 4.41 g/kg of potassium is recommended in the diet for laying Japanese quails.

    The effect of shrimp meal (SM) was measure in commercial laying hen diets. Pleuroncodes planipes was used in Costa Rica, from April to September 2013, to obtain a meal (SM) with a yield of 15%, particle size of 256 μg and negative for Salmonella sp. Proximate analysis was performed to the SM: crude protein (40,67%), ether extract (11,05%), crude fiber (7,12%), ash (27,48%), calcium (9,03%), phosphorus (2,66%), amino acid profile, pepsin digestibility (84%) and acidity (8,34). Subsequently, a trial was performed with 140 40-week-old Hy-Line Brown laying hens, fed with four different diets containing increasing levels of inclusion of SM (0%, 5%, 10%, and 15%) during four weeks; and formulated according to the ideal protein and digestible amino acids concepts; being isocaloric and isoproteic. The variables experimentally evaluated were: production percentage, feed intake, body weight, mortality, egg weight and feed conversion ratio. Only egg weight changed significantly between treatments in the third week (p [es

    1. A 3-year trial was carried out of cages for laying hens, occupying a full laying house. The main cage designs used were 5000 cm2 in area, 50 cm high at the rear and furnished with nests and perches. F cages had a front rollaway nest at the side, lined with artificial turf. FD cages also had a dust bath containing sand over the nest. H cages had two nest hollows at the side, one in front of the other. They were compared with conventional cages 2500 cm2 in area and 38 cm high at the rear. 2. Cages were stocked with from 4 to 8 ISA Brown hens per cage, resulting in varied allowances of area, feeder and perch per bird. No birds were beak trimmed. In F and FD cages two further treatments were applied: nests and dust baths were sometimes fitted with gates to exclude birds from dust baths in the morning and from both at night; elevated food troughs, with a lip 33 cm above the cage floor, were compared with standard troughs. 3. Management of the house was generally highly successful, with temperature control achieved by ventilation. Egg production was above breeders' standards and not significantly affected by cage design. More eggs per bird were collected when there were fewer birds per cage but food consumption also then tended to be higher. 4. The number of downgraded eggs was variable, with some tendency for more in furnished cages. Eggs laid in dust baths were often downgraded. Those laid at the back of the cage were frequently dirty because of accumulation of droppings. H nests were unsuccessful, with less than 50% of eggs laid in the nest hollows. However, up to 93% of eggs were laid in front rollaways, and few of these were downgraded. 5. Feather and foot damage were generally less in furnished than in conventional cages, greater where there were more birds per cage. With an elevated food trough there was less feather damage but more overgrowth of claws. In year 2, mortality was greater in cages with more birds. 6. Pre-laying behaviour was mostly settled in

    To function effectively within the multifaceted environment of the academic medical center, academic physicians need to heighten their understanding of the economics of the health care system, and further develop their leadership and managerial skills. A literature base on organizational development and management education now exists that addresses the unique nature of the professional organization, including academic medical centers. This article describes an administration development curriculum for academic physicians. Competency statements, instructional strategies and references provide the academic physician with guidelines for expanding their professional expertise to include organizational and management skills. The continuing success of the academic medical center as a responsive health care system may depend upon the degree to which academic physicians gain sophistication in self-management and organizational administration.

    Levels of social support are strongly associated with health outcomes and inequalities. The use of lay health workers (LHWs) has been suggested by policy makers across the world as an intervention to identify risks to health and to promote health, particularly in disadvantaged communities. However, there have been few attempts to theorize the work undertaken by LHWs to understand how interventions work. In this article, the authors present the concept of 'synthetic socialsupport' and distinguish it from the work of health professionals or the spontaneous social support received from friends and family. The authors provide new empirical data to illustrate the concept based on qualitative, observational research, using a novel shadowing method involving clinical and non-clinical researchers, on the everyday work of 'pregnancy outreach workers' (POWs) in Birmingham, UK. The service was being evaluated as part of a randomized controlled trial. These LHWs provided instrumental, informational, emotional and appraisal support to the women they worked with, which are all key components of social support. The social support was 'synthetic' because it was distinct from the support embedded in spontaneous social networks: it was non-reciprocal; it was offered on a strictly time-limited basis; the LHWs were accountable for the relationship, and the social networks produced were targeted rather than spontaneous. The latter two qualities of this synthetic form of social support may have benefits over spontaneous networks by improving the opportunities for the cultivation of new relationships (both strong and weak ties) outside the women's existing spontaneous networks that can have a positive impact on them and by offering a reliable source of health information and support in a chaotic environment. The concept of SSS can help inform policy makers about how deploying lay workers may enable them to achieve desired outcomes, specify their programme theories and evaluate

  12. The lay concept of conduct disorder: do nonprofessionals use syndromal symptoms or internal dysfunction to distinguish disorder from delinquency?

    Conduct disorder (CD) must be distinguished from nondisordered delinquent behaviour to avoid false positives, especially when diagnosing youth from difficult environments. However, the nature of this distinction remains controversial. The DSM-IV observes that its own syndromal CD diagnostic criteria conflict with its definition of mental disorder, which requires that symptoms be considered a manifestation of internal dysfunction to warrant disorder diagnosis. Previous research indicates that professional judgments tend to be guided by the dysfunction requirement, not syndromal symptoms alone. However, there are almost no data on lay conceptualizations. Thus it remains unknown whether judgments about CD are anchored in a broadly shared understanding of mental disorder that provides a basis for professional-lay consensus. The present study tests which conception of CD, syndromal-symptoms or dysfunction-requirement, corresponds most closely to lay judgments of disorder or nondisorder and compares lay and professional judgments. We hypothesized that lay disorder judgments, like professional judgments, tend to presuppose the dysfunction requirement. Three lay samples (nonclinical social workers, nonpsychiatric nurses, and undergraduates) rated their agreement that youths described in clinical vignettes have a mental disorder. All vignettes satisfied DSM-IV CD diagnostic criteria. Vignettes were varied to present syndromal symptoms only, symptoms suggesting internal dysfunction, and symptoms resulting from reactions to negative circumstances, without dysfunction. All lay samples attributed disorder more often to youths whose symptoms suggested internal dysfunction than to youths with similar symptoms but without a likely dysfunction. The dysfunction requirement appears to reflect a widely shared lay and professional concept of disorder.

  13. The Role of Academic Science

    1996-02-01

    Increasingly, new science and technology are expected to solve the nation's current economic malaise. Unfortunately, virtually no industrial laboratories are devoted to anything close to basic research, which, historically, has been the source of many of the innovations on which industry has flourished in the past. For example, a number of industrial laboratories contributed significantly to our basic understanding of polymer science and, in the course of doing so, made better and more useful plastics. The strength of the American system of higher education has always been basic research, which is also the cornerstone of the process of graduate education. Before World War II, academic research was the vehicle by which advanced students learned advanced skills--both cognitive and manipulative. It was the structure devised to produce exemplary scientists who could then apply their skills in a number of different kinds of environments; the research results produced were generally of only secondary interest. Now, the academic research establishment has evolved into the source of the "strategic," "relevant," or "targeted" research that will solve the nation's economic problems. As expectations in this regard grow higher, guidelines are bound to become even more specific. Excessive over-direction of basic research activities can have the effect of throttling down the very industry-building discoveries that are so eagerly sought. From one point of view, targeted academic research often goes in the wrong direction. While it is true that most academic research starts off in some direction, it often does not finish going in that direction. The work that stands behind theses and dissertations often bears little resemblance to the problem that was defined when the student began his/her research.

    2011-03-01

    We describe a geometrical property of helical structures and show how it accounts for the early art of rope-making. Helices have a maximum number of rotations that can be added to them — and it is shown that this is a geometrical feature, not a material property. This geometrical insight explains why nearly identically appearing ropes can be made from very different materials and it is also the reason behind the unyielding nature of ropes. Maximally rotated strands behave as zero-twist structures. Hence, under strain they neither rotate in one direction nor in the other. The necessity for the rope to be stretched while being laid, known from Egyptian tomb scenes, follows straightforwardly, as does the function of the top, an old tool for laying ropes.

  15. Optimization of wet lay-up conditions for steam generators hydrazine chemical treatment

    Since a long time, hydrazine is used as a chemical agent to prevent corrosion of unalloyed steels. This is a conventional treatment widely used by nuclear power plant operators. But its application in SG lay-up at French nuclear power plants has, however, lead to some drawbacks. Effluent releases: Due to regulation relative to release of hydrazine and alkaline chemical compounds, some plant operators limit the concentrations of reagents to levels that could lead to insufficient protection of materials. Safety hazards associated with SG nitrogen blanketing: Prohibiting use of nitrogen blankets for SG wet lay-up due to associated safety hazards could likewise jeopardize corrosion protection at normally specified hydrazine levels. As the exact limits of hydrazine action against corrosion during SG lay-up are not well known, it is sometimes difficult to evaluate the risk associated to low dosage of N 2 H 4 . In order to answer to these problems, Framatome ANP (France) decided to carry out a test program aimed to determine the limit conditions for use of hydrazine in a wet lay-up environment. (authors)

  8. Lay health advisers: scoping the role and intervention landscape.

    Science.gov (United States)

    Carr, Susan M; Lhussier, Monique; Forster, Natalie

    2017-01-01

    The use of lay health advisers has become an established approach within public health, in particular for impact on health inequalities and engaging socially excluded groups. Evidence on how differences in terms of the multiple role dimensions impact the outcomes of programs is limited. This creates ambiguity for decision makers on which roles should be implemented in different contexts for different needs. This paper applies realist logic to an inquiry to explore the mechanisms that may operate in lay-led intervention models and understand how, why, and in what respect these lead to particular outcomes. It draws on a project focusing on health-related lifestyle advisers and further insights gained from a subsequent related project about outreach with traveler communities. Analysis highlights multiple and potentially interacting aspects of lay health-adviser roles that may influence their success, including characteristics of lay health advisers, characteristics of target populations, purpose or intent of interventions, and how advice is given. A model is proposed from which to examine the contexts and mechanisms of lay health advisers that may impact outcomes, and is subsequently applied to two examples of reported lay health-adviser interventions. The combination of skills and characteristics of lay health advisers must be considered when planning which interventions might be appropriate when targeting specific needs or target populations. Focus only on the peer/layperson distinction may overlook other potentially important skills and mechanisms of action integral to lay health-adviser roles.

  10. Whistleblowing in academic medicine.

    Rhodes, R; Strain, J J

    2004-02-01

    Although medical centres have established boards, special committees, and offices for the review and redress of breaches in ethical behaviour, these mechanisms repeatedly prove themselves ineffective in addressing research misconduct within the institutions of academic medicine. As the authors see it, institutional design: (1) systematically ignores serious ethical problems, (2) makes whistleblowers into institutional enemies and punishes them, and (3) thereby fails to provide an ethical environment. The authors present and discuss cases of academic medicine failing to address unethical behaviour in academic science and, thereby, illustrate the scope and seriousness of the problem. The Olivieri/Apotex affair is just another instance of academic medicine's dereliction in a case of scientific fraud and misconduct. Instead of vigorously supporting their faculty member in her efforts to honestly communicate her findings and to protect patients from the risks associated with the use of the study drug, the University of Toronto collaborated with the Apotex company's "stalling tactics," closed down Dr Olivieri's laboratory, harassed her, and ultimately dismissed her. The authors argue that the incentives for addressing problematic behaviour have to be revised in order to effect a change in the current pattern of response that occurs in academic medicine. An externally imposed realignment of incentives could convert the perception of the whistleblower, from their present caste as the enemy within, into a new position, as valued friend of the institution. The authors explain how such a correction could encourage appropriate reactions to scientific misconduct from academic medicine.

    Brock, Laura L; Nishida, Tracy K; Chiong, Cynthia; Grimm, Kevin J; Rimm-Kaufman, Sara E

    2008-04-01

    This study examines the contribution of the Responsive Classroom (RC) Approach, a set of teaching practices that integrate social and academic learning, to children's perceptions of their classroom, and children's academic and social performance over time. Three questions emerge: (a) What is the concurrent and cumulative relation between children's perceptions of the classroom and social and academic outcomes over time? (b) What is the contribution of teacher's use of RC practices to children's perceptions and social and academic outcomes? (c) Do children's perceptions of the classroom mediate the relation between RC teacher practices and child outcomes? Cross-lagged autoregressive structural equation models were used to analyze teacher and child-report questionnaire data, along with standardized test scores collected over 3 years from a sample of 520 children in grades 3-5. Results indicate a significant positive relation between RC teacher practices and child perceptions and outcomes over time. Further, children's perceptions partially mediated the relation between RC teacher practices and social competence. However, the models did not demonstrate that child perceptions mediated the relation between RC practices and achievement outcomes. Results are explained in terms of the contribution of teacher practices to children's perceptions and student performance.

  15. Training Lay Interventionists to Support Tobacco Cessation among Teachers in India.

    2016-01-01

    Despite the rapidly increasing burden of tobacco-related morbidity and mortality in low- and middle-income countries, tobacco control initiatives - especially cessation - receive little emphasis. This is true despite low-cost methods that have potential for widespread dissemination. The purpose of this paper is to provide a case study example of how lay interventionists may be trained and supported to facilitate tobacco use cessation, based on the successful Tobacco Free Teachers-Tobacco Free Society program (TFT-TFS) implemented in Bihar, India. This school-based program included multiple components, with lay interventionists having a crucial role. The lay interventionists included health educators and lead teachers, both of whom were selected based on formative research, underwent extensive training and received continuing support. We emphasized encouraging and supporting teachers to quit tobacco use and engaging both tobacco users and nonusers to create a supportive environment for cessation. We also stressed that neither the health educators nor lead teachers were being trained as counselors or as cessation experts. We focused on the importance of respecting teachers as individuals and identifying locally relevant methods of cessation. Although we cannot isolate the precise contribution of the lay interventionists to the successful TFT-TFS intervention, the abstinence findings in favor of the intervention at follow up are highly encouraging. Teachers have been neglected as lay interventionists for tobacco cessation despite the fact that they tend to be highly respected and credible. The approach used for TFT-TFS could be disseminable in multiple low- and middle-income country contexts through train-the-trainer programs targeted to teachers.

  16. Lay perspectives on lay health worker roles, boundaries and participation within three UK community-based health promotion projects.

    Science.gov (United States)

    South, J; Kinsella, K; Meah, A

    2012-08-01

    This paper examines lay interpretations of lay health worker roles within three UK community-based health promotion projects. It argues that understanding lay health worker roles requires critical analysis of the complex interrelationships between professionals, lay workers and the communities receiving a programme. Findings are presented that are drawn from a qualitative study of lay engagement in public health programme delivery where a key objective was to examine the perspectives of community members with the experience of receiving services delivered by lay health workers. Interviews and focus groups were conducted with 46 programme recipients from three case study projects; a breastfeeding peer support service, a walking for health scheme and a neighbourhood health project. The results show how participants interpreted the function and responsibilities of lay health workers and how those roles provided personalized support and facilitated engagement in group activities. Further insights into community participation processes are provided revealing the potential for active engagement in both formal and informal roles. The paper concludes that social relationships are core to understanding lay health worker programmes and therefore analysis needs to take account of the capacity for community members to move within a spectrum of participation defined by increasing responsibility for others.

    One of the objectives of the National Waste Terminal Storage (NWTS) Program is to provide terminal storage facilities for commercial radioactive wastes in various geologic formations at multiple locations in the United States. The activities performed under the NWTS Program will affect regional, state, and local areas, and widespread public interest in this program is expected. Since a large part of the NWTS Program deals with technical information it was considered desirable to initiate a study dealing with possible methods of effectively transmitting this technical information to the general public. This study has the objective of preparing a state-of-the-art report on the communication of technical information to lay audiences. The particular task of communicating information about the NWTS Program to the public is discussed where appropriate. The results of this study will aid the NWTS Program in presenting to the public the quite diverse technical information generated within the program so that a widespread, thorough public understanding of the NWTS Program might be achieved.

    Marin, Sorin

    2017-11-01

    This article describes the first stage in the history of Romanian astronomy represented by the events, processes and evolution which led to the formation of great scientific personalities, development drives and the creation of the material base for the contemporary Romanian astronomy, having a focus point on the activity of Bucharest Observatory. The article discusses the roots of an evolution pathway determined and inspired by the activity of several scientific personalities of Romania such as Stefan Hepites, Spiru Haret, Nicolae Coculescu and others. It also underlines that a great importance for the astronomical research in Romania was given by the outstanding technical value of the main instruments used at the Observatory in the first decades of activity and, consequentially, by their longevity in service: in the Equatorial Dome - the impressive 6 m. Prin-Mertz telescope and in the Meridian Hall - the GautierPrin telescope. This determined the formation of a powerful astrometry division and a research drive which led over time to important scientific works such as the ultraprecise stellar catalogues developed in Romania at Bucharest Observatory, which were appreciated and awarded nationally and internationally. Therefore, the article includes the moments and the people which determined the success of laying the foundations of the Observatory in 1908 and then having completed the initial scientific infrastructure in 1912 when the construction work was finished, and briefly presents the features, scientific utilisation and outputs of its telescopes, some of the best in the world in their golden years.

  20. The conspiratorial style in lay economic thinking

    Science.gov (United States)

    2017-01-01

    This study investigates patterns of lay perception of economics, and in particular the place of conspiratorial thinking regarding the economic domain. We devised four types of accounts in the economic domain, over a range of questions regarding different aspects of the economy: the classical neo-liberal economic view (which we labeled Econ101), and the Conspiracy view (the destructive outcomes of economy are due to small and powerful groups who are manipulating the markets), to which we added the Government malfunction view (failures in the economy are due to the authorities), and the Bad Invisible Hand view (the invisible hand may go wrong, and the equilibrium reached by its doings may be undesirable). The last two views are the ones most strongly endorsed by our respondents, in the US, Israel and Switzerland. The pattern of inter-correlations between the four accounts, and that between each and the psycho-social variables we examined, exhibits two clusters, Econ101 vs. the other three views of economy. This corresponds to a general opposition between people who trust the neoliberal economic system, and those opposed to it. What sets economic conspiratorial thinking apart are its links with other conspirational beliefs and with paranormal beliefs. PMID:28257506

    Jago, Arthur S; Laurin, Kristin

    2017-03-01

    Modern conceptions of corporate personhood have spurred considerable debate about the rights that society should afford business organizations. Across eight experiments, we compare lay perceptions of how corporations and people use rights, and also explore the consequences of these judgments. We find that people believe corporations, compared to humans, are similarly likely to use rights in protective ways that prevent harm but more likely to use rights in nonprotective ways that appear independent from-or even create-harm (Experiments 1a through 1c and Experiment 2). Because of these beliefs, people support corporate rights to a lesser extent than human rights (Experiment 3). However, people are more supportive of specific corporate rights when we framed them as serving protective functions (Experiment 4). Also as a result of these beliefs, people attribute greater ethical responsibility to corporations, but not to humans, that gain access to rights (Experiments 5a and 5b). Despite their equitability in many domains, people believe corporations and humans use rights in different ways, ultimately producing different reactions to their behaviors as well as asymmetric moral evaluations.

    2018-04-01

    Underground cable laying is an alternative for overhead cable laying of telecommunication and power transmission lines. It is becoming very popular in recent times because of some of its advantages over overhead cable laying. This type of cable laying is mostly practiced in developed countries because it is more expensive than overhead cable laying. Underground cable laying is more suitable when land is not available, and it also increases the aesthetics. This paper implements the automation on a manually operated cable pulling winch machine using programmable logic controller (PLC). Winch machines are useful in underground cable laying. The main aim of the project is to replace all the mechanical functions with electrical controls which are operated through a touch screen (HMI). The idea is that the machine should shift between parallel and series circuit automatically based on the pressure sensed instead of manually operating the solenoid valve. Traditional means of throttling the engine using lever and wire is replaced with a linear actuator. Sensors such as proximity, pressure and load sensor are used to provide the input to the system. The HMI used will display the speed, length and tension of the rope being winded. Ladder logic is used to program the PLC.

    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.

    Full Text Available 1. Universities are the institutions where all the opinions, various truth claims as well as social and political problems are discussed in a liberal and civilized way and the complicated problems are expressed clearly without any oppression and prevention. 2. Academic freedom includes first and foremost the right of freedom of research and thus freedom of using the essential knowledge methods, the right of possessing the necessary tools and conditions required for the research and the rights of scientific production, informing, learning and dissemination. 3. Academics possess the rights to benefit from the academic freedom without any limitation, to research and investigate according to their own preferences and interests, and to teach these without being exposed to any oppression and prevention. 4. This freedom of teaching that the academics have should not be used in a manner restricting students' freedom of learning; academics should avoid from being dogmatic in the research and education processes and respect students' rights of thinking differently and expressing themselves. 5. Academics accordingly should lead the students to evaluate and understand the new thoughts as a whole and to be tolerant to the thoughts they do not agree and to think in various ways. Also, academics should encourage the students to create their own opinions based on evidences and enable them to express these opinions freely and respect their freedom of expression. 6. Campuses should be safe environments where the students can express their own opinions freely. Suppressing the intellectual diversity and the plurality of viewpoints will decrease the productivity of teaching and learning process, restrict students' freedom of learning, and constrain the chance of formation of critical and in-depth thinking. 7. Critical thinking develops only in the campuses where various thoughts are expressed in a liberal way. Students should feel that they would not be prevented

  7. Early Onset of Laying and Bumblefoot Favor Keel Bone Fractures

    Science.gov (United States)

    Gebhardt-Henrich, Sabine G.; Fröhlich, Ernst K. F.

    2015-01-01

    Simple Summary Numerous studies have documented a high prevalence of keel bone fractures in laying hens. In this longitudinal study, 80 white and brown laying hens were regularly checked for keel bone deviations and fractures while egg production was individually monitored. About 62% of the hens had broken keel bones at depopulation. More new fractures occurred during the time when laying rates were highest. Hens with broken keel bones at depopulation had laid their first egg earlier than hens with intact keel bones. All birds with bumblefoot on both feet had a fracture at depopulation. Abstract Numerous studies have demonstrated influences of hybrid, feed, and housing on prevalence of keel bone fractures, but influences of behavior and production on an individual level are less known. In this longitudinal study, 80 white and brown laying hens were regularly checked for keel bone deviations and fractures while egg production was individually monitored using Radio Frequency Identification (RFID) from production until depopulation at 65 weeks of age. These focal birds were kept in eight pens with 20 hens per pen in total. About 62% of the hens had broken keel bones at depopulation. The occurrence of new fractures was temporally linked to egg laying: more new fractures occurred during the time when laying rates were highest. Hens with fractured keel bones at depopulation had laid their first egg earlier than hens with intact keel bones. However, the total number of eggs was neither correlated with the onset of egg laying nor with keel bone fractures. All birds with bumblefoot on both feet had a fracture at depopulation. Hens stayed in the nest for a longer time during egg laying during the ten days after the fracture than during the ten days before the fracture. In conclusion, a relationship between laying rates and keel bone fractures seems likely. PMID:26633520

    2012-01-01

    Gregarious nesting can be defined as a behaviour that occurs when a laying hen (Gallus gallus domesticus) given the choice between an occupied and an unoccupied nest site chooses the occupied nest site.

    Full Text Available The principles for the formation of forest typological classification and outlines promising areas for development, allowing to solve problems of not only inventory and forest management, but also mapping forest types are discussed in the paper. The analysis is performed by interpreting the concept of «natural regularity» proposed by D. L. Armand (1975. It is shown when the left side of the pattern is a set of indicators of site condition, structure of forest typological constructions will take into account not only the static indicators of the stands, but also their location, the origin and direction of the succession. For relatively similar climatic conditions, the indicators of the lay of land mainly limit the environment of formation of vegetation cover. The method of mapping forest types provides for consideration of site condition and indicators of stands of forest types. Testing is conducted on a test axis West-Sayan forest district, located in the mountains of southern Siberia. Conjugation types of forests, indicators of the topography revealed through the analysis of literary sources and characteristics of forest types accompanying diagnostic table (Smagin et al., 1980. The work is done in a GIS environment using DEM SRTM and Landsat space images. For indexing locations, the inputs are accepted: altitude (gradation 100 m, flat location, slope up to 20° and 20° slopes with northern and southern exposure. Classification of pixels of satellite images is conducted by the method of unsupervised classification separately for each scene, the high-altitude zone and location, which allows increase of the quality of interpretation, because the types of forests are confined to the topography. However completely avoiding mistakes is not possible. The main reasons are an inaccuracy of the DEM and the hit in one class of spectral brightness of different objects of interpretation.

    2016-09-20

    Happiness is a topic that ignites both considerable interest and considerable disagreement. Thus far, however, there has been little attempt to characterize people's lay theories about happiness or explore their consequences. We examined whether individual differences in lay theories of happiness would predict empathy. In Studies 1a and 1b, we validated the Lay Theories of Happiness Scale (LTHS), which includes three dimensions: flexibility, controllability, and locus. In Study 2, higher dispositional empathy was predicted by the belief that happiness is flexible, controllable, and internal. In Studies 3 and 4, higher empathy toward a specific target was predicted by the belief that happiness is flexible, uncontrollable, and external In conjunction, Studies 2, 3, and 4 provide evidence that trait and state empathy are separable and can have opposing relationships with people's lay theories. Overall, these findings highlight generalized beliefs that may guide empathic reactions to the unhappiness of others. © 2016 by the Society for Personality and Social Psychology, Inc.

    This paper seeks to empirically explore the claim that translated Danish Patient Information Leaflets (PILs) are less lay-friendly than their English source texts. The last two decades have seen an increased focus on providing patients with lay-friendly, easily understood information, enabling them...... to make informed decisions concerning their health. For this purpose, many new genres have been created, one such genre being the PIL, a mandatory text which in an EU context has to accompany all medication informing patients about dosage, side effects etc. Legally, the PIL genre is required to ensure lay......-friendly information as it must be “written and designed to be clear and understandable, enabling the users to act appropriately” (Article 63(2) of EU Directive 2001/83/EC).

  15. Medullary bone and humeral breaking strength in laying hens

    International Nuclear Information System (INIS)

    Fleming, R.H.; McCormack, H.A.; McTeir, L.; Whitehead, C.C.

    1998-01-01

    To test the hypothesis that large amounts of medullary bone in the humeral diaphysis may increase breaking strength, various parameters of bone quality and quantity were examined in two large flocks of hens near end of lay. We conclude that the amount of medullary bone in the humerus of hens during the laying period influences bone strength. This medullary bone may not have any intrinsic strength, but may act by contributing to the fracture resistance of the surrounding cortical bone. Using a quantitative, low dose, radiographic technique, we can predict, from early in the laying period, those birds which will develop large amounts of medullary bone in their humeri by the end of the laying period. The formation of medullary bone in the humeral diaphysis is not at the expense of the surrounding radiographed cortical bone

    This article deals with virtual tools based on principles of open source philosophy in implementation area of composite lay-up technology. It describes virtual software and hardware elements that are necessary for work in augmented reality environment. In the beginning it focuses on general problems of applications of virtual components and in composite lay-up process. It clarifies the fundamental philosophy of new created application and the process called visual scripting that was used for program development. Further it provides closer view on particular logical sections, where necessary data are harvested and compared with values from virtual arrays. Also the new device is described with adjustment of operating desk, what enables detailed control of any realized manufacturing process. This positioning table can determine and set the position of the working plane using the commands in computer interface or manual changes. Information about exact position of individual layers are obtained in real time thanks to the built-in sensors. One of them manages the data change of the desk position (X, Y, Z), other checks the rotation around main axis situated in the center of the table. New software consists of 4 main logical areas with data packets comming from internal computer components as well as from external devices. In the end the displaying section is able to realize the movement process of virtual item (composite layer) according to its trajectory. Article presents new attitude in realization of composite lay-up process. Finally it deals with possible future improvements and other application possibilities.

    2018-03-28

    The oversupply of dietary phosphorus (P) leads to increased feed costs and discharge of excessive P to the environment, thus directly impacting the sustainability of egg production practices. The present study was conducted to better define the minimal available P needs of laying hens. Fifty-six Lohmann white laying hens were individually caged and fed one of 7 diets with graded levels of available P (0.15, 0.20, 0.25, 0.30, 0.35, 0.40, or 0.45%) for 12 weeks. Records were maintained for body weight, feed intake, and egg production during the experimental period. Blood and egg samples were collected and digestibility studies conducted at wk 6 and 12 of the experiment. At the end of the experiment, tibia characteristics and expression of the P transporters in the small intestine and kidney were determined. Lowering dietary available P from 0.45 to 0.15% generally reduced plasma P concentrations (P data indicate that reducing dietary available P up to 0.15% is adequate to maintain health and performance of layers. As such, this minimal available P estimate should serve as a benchmark for the assessment of P contents of commercial laying hen rations, with the goal of enhancing the sustainability of egg production.

  3. South Asian participation in clinical trials: the views of lay people and health professionals.

    2006-07-01

    There is little UK-based empirical research on South Asian participation in clinical trials. The predominantly US literature rarely engages with mainstream debates about ethnicity, diversity and difference. This study was prompted by a lack of knowledge about how South Asian people perceive trial involvement and the risks and benefits involved. Face to face interviews were conducted with 25 health professionals (consultants, GPs, nursing staff, academics, non-medically trained trial co-ordinators, LREC and MREC members) and 60 South Asian lay people (20 Indians, 20 Pakistanis and 20 Bangladeshis) who had not taken part in a trial. The study took place in the Leeds and Bradford areas of England. It was found that lay South Asian attitudes towards clinical trial participation focused on similarities rather than differences with the general UK population, suggesting that the relevance of ethnicity should be kept in perspective. There was no evidence of antipathy amongst South Asians to the concept of clinical trials, and awareness was a correlate of social class, education and younger age. Lay factors that might affect South Asian participation in clinical trials included: age; language, social class; feeling of not belonging/mistrust; culture and religion. Approachable patients (of the same gender, social class and fluent in English) tended to be 'cherry picked' to clinical trials. This practice was justified because of a lack of time, resources and inadequate support. South Asian patients might be systematically excluded from trials due to the increased cost and time associated with their inclusion, particularly in relation to the language barrier. Under-representation might also be due to passive exclusion associated with cultural stereotypes. The paper concludes by applying the theoretical framework of institutional racism as a means of making sense of policy and practice. At the same time, caution is advocated against using ethnicity as the only form of

    A 42-d study with 384 Hy-line brown laying hens was conducted to assess the effects of dietary octacosanol supplementation on laying performance, egg quality and blood metabolites of laying hens. Hens were randomly allocated into 4 dietary groups of 8 cages each, which were fed basal diet supplemented with 0 (Control), 9 (OCT9), 18 (OCT18), and 27 (OCT27) mg/kg diet of octacosanol isolated from rice bran, respectively. The experiment was conducted in an environmental controlled house and hens were fed twice daily for ad libitum intake. Laying performance was determined over the 42-d period, and egg quality as well as blood metabolites were estimated on d 21 and d 42. Diets in OCT18 and OCT27 increased (pfeed conversion rate and levels of total cholesterol, triglyceride and low density lipoprotein cholesterol in the serum as compared to those of Control. Feed intake, yolk color, yolk diameter, eggshell thickness and high density lipoprotein cholesterol were similar (p>0.05) among treatments. Results demonstrate that supplementing 18 to 27 mg/kg diet of rice bran octacosanol can improve laying rate and egg quality and reduce blood lipid of laying hens.

    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.

    Full Text Available To measure the role of anxiety and non-clinical depression as predictors of academic stress. In this study, supplementary objective had been gauging the prevalence of anxiety and depression among medical students of first year and final year, sought from six major medical colleges of Punjab. Almost all health professionals, no matter to which part of the world they belong to, face anxiety, depression and stress due to the nature of services they have to extend in medical profession such as time-pressures, workload, multiple roles and emotional issues. Quantitative research designed was employed; and cross sectional research design was used to lay out the research. The data was collected from first year and final year medical students. The duration of data collection was from Sep, 2014 to Sep, 2015. In Faculty of Medicine of five leading medical colleges, with total number of 650 students, the prevalence of anxiety and depression was found to be 83.9% and 67.9%, from first year to fourth year respectively, based on the cut-off points of both questionnaires. There was significant association among anxiety, depression and academic stress as computed through Pearson Product Moment Correlation. The regression analyses revealed that depression was significant predictor of academic stress but this was not the same for anxiety. Females were more anxiety and depression prone and reported greater academic stress than males. The study revealed significant distress among medical students, in terms of both anxiety and depression. It was inferred that the depression acts as pertinent predictor of academic stress. Furthermore, it was noticed that the prevalence of symptoms was higher among females. The findings carry significant implications for highlighting the addressing the need for psychological wellbeing of medical students in order to establish conducive environment of learning for medical professionals.

  9. Civil Justice: Lay Judges in the EU Countries

    Full Text Available Lay judges fulfill important functions for the justice system of a country. In the European Union member states, scholars have analysed the use of lay judges in criminal cases. However, little is known about lay participation in civil justice. The paper introduces commonly cited reasons to have lay judges as well as the principal forms of lay participation and then surveys the EU countries for its implementation in civil cases. Mixed tribunals, involving lay judges under the leadership of a professional judge, are relatively frequent. Several countries have special labour courts or commercial courts with lay members and others have single lay judges, or all-lay judge panels. Roughly a third of the 28 EU member states have no lay participation in civil justice but only three of those have no lay judges in any branch of the courts. Almost all the reasons for including lay decision makers are served somehow by the existing forms, including providing different experiences and perhaps expert knowledge. The article concludes, citing non-EU states and lay participation in criminal and administrative courts as further evidence, that lay judges in one form or another are an element of European legal systems. Los jueces legos cumplen funciones importantes para el sistema de justicia de un país. En los Estados miembro de la Unión Europea, académicos han analizado el uso de jueces legos en casos criminales.

    This article describes the process our community-academic partnership used to lay the groundwork for successful implementation of an adolescent-focused, evidence-based HIV/AIDS prevention curriculum in two Black churches. We highlight the challenges encountered and lessons learned in building a relationship with two churches, garnering the pastor's support, and implementing the curriculum within church youth groups. We engaged a Community Advisory Board (CAB) made up of youth, parents, and diverse faith leaders to ensure community relevance and guide project development, implementation, and evaluation. Using a community-based participatory research (CBPR) approach helped us to (1) engage diverse, intergenerational community members, (2) initiate a "culturally humble" process to build relationships with faith leaders, (3) remain responsive to stakeholder concerns, and (4) open the door to HIV prevention in the Black church. Finding effective and responsive ways to implement HIV/AIDS prevention in faith settings is facilitated by engaging diverse partners throughout the research process.

    The author's purpose through this study was to document and analyze health provider perceptions of their social work environment and the state of pediatric care at Los Angeles County King/Drew Hospital and Medical Center in 2000, after the restructuring and downsizing of the hospital and its community clinics. The research results showed nurses and physicians reporting that both the quality of pediatric care and the provider social work environment were poor. Negative factors in the social work environment included: low employee morale, poorly staffed clinical teams, lack of professional autonomy, perceptions of low quality of care for pediatric patients, and interpersonal issues of poor communication and collaboration among providers. Providers also perceived a non-supportive work environment, sense of powerlessness, poor quality of work, lack of goal clarity from leadership, lack of fairness in leadership behavior, and an organizational leadership that is abandoning its core mission and values, thereby making it difficult for providers to carry out their professional functions. The author's findings in this study suggest a relationship between intra-role conflict, social employment environment and quality of care at King/Drew Medical Center in 2000. Lessons for practice are presented.

Na análise da qualidade dos ovos, foram avaliados o peso, a unidade Haugh, a gravidade específica, a espessura, a integridade e a limpeza da casca dos ovos. Não foram observadas diferenças no desempenho produtivo entre sistemas de criação e linhagens. O sistema de criação em cama, quando devidamente projetado, pode ser compatível ao de criação em gaiolas quanto ao desempenho produtivo e à qualidade de ovos produzidos. Além disso, quando em condições menos favoráveis ao conforto térmico, esse sistema de criação pode propiciar melhores resultados de qualidade da casca, com menores perdas de ovos, no entanto, pode resultar em maior porcentagem de ovos sujos, principalmente para a linhagem semipesada.This work aimed to evaluate the effect of two different rearing systems (cages and litter on productive performance and egg quality of laying hens.

    The HIV testing, treatment and care programme of the South African public healthcare system depends on HIV counselling and testing (HCT) that is primarily delivered by lay counsellors. Lay counsellors are expected to educate clients about HIV/AIDS, advocate behaviour change, convey test results and support those infected and affected to cope with the emotional and social challenges associated with HIV/AIDS. This research focuses on the emotional wellbeing of lay HCT counsellors because this influences the quality of services they provide. A mixed methods approach was used. The emotional wellbeing, level of burnout, depression and coping style of 50 lay HCT counsellors working at the City of Tshwane clinics were assessed. Additionally, five focus group discussions were conducted. The results showed that HCT counsellors reported average emotional wellbeing, high levels of emotional exhaustion and depression. They had a sense of personal accomplishment and positive coping skills. The results revealed that they may have difficulty dealing with clients' emotional distress without adequate training and supervision. This creates a dilemma for service delivery. In the light of the important role they play in service delivery, the role of the lay HCT counsellor needs to be reconsidered. HCT should develop as a profession with specific training and supervision to develop their emotional competencies to conduct effective counselling sessions.

    Lay navigators in the Patient Care Connect Program support patients with cancer from diagnosis through survivorship to end of life. They empower patients to engage in their health care and navigate them through the increasingly complex health care system. Navigation programs can improve access to care, enhance coordination of care, and overcome barriers to timely, high-quality health care. However, few data exist regarding the financial implications of implementing a lay navigation program. To examine the influence of lay navigation on health care spending and resource use among geriatric patients with cancer within The University of Alabama at Birmingham Health System Cancer Community Network. This observational study from January 1, 2012, through December 31, 2015, used propensity score-matched regression analysis to compare quarterly changes in the mean total Medicare costs and resource use between navigated patients and nonnavigated, matched comparison patients. The setting was The University of Alabama at Birmingham Health System Cancer Community Network, which includes 2 academic and 10 community cancer centers across Alabama, Georgia, Florida, Mississippi, and Tennessee. Participants were Medicare beneficiaries with cancer who received care at participating institutions from 2012 through 2015. The primary exposure was contact with a patient navigator. Navigated patients were matched to nonnavigated patients on age, race, sex, cancer acuity (high vs low), comorbidity score, and preenrollment characteristics (costs, emergency department visits, hospitalizations, intensive care unit admissions, and chemotherapy in the preenrollment quarter). Total costs to Medicare, components of cost, and resource use (emergency department visits, hospitalizations, and intensive care unit admissions). In total, 12 428 patients (mean (SD) age at cancer diagnosis, 75 (7) years; 52.0% female) were propensity score matched, including 6214 patients in the navigated group and 6214

    The concept of lay worker health literacy is created by concurrently analyzing and synthesizing two intersecting concepts, lay workers and health literacy. Articulation of this unique intersection is the result of implementing a simplified Wilson's Concept Analysis Procedure. This process incorporates the following components: a) selecting a concept, b) determining the aims/purposes of analysis, c) identifying all uses of the concept, d) determining defining attributes, e) identifying a model case, f) identifying borderline, related, contrary, and illegitimate cases, g) identifying antecedents and consequences, and h) defining empirical referents. Furthermore, as current literature provides no operational definition for lay worker health literacy, one is created to contribute cohesion to the concept. © 2017 Wiley Periodicals, Inc.

    Nowadays the phenomenon of academic misconduct (such as plagiarism, fabrication, falsification, etc.) is very frequent. The reasons for academic misconduct are involved in the problems in graduate education system, social environment and students themselves. Therefore, colleges and universities should place great emphasis on constructing a healthy school environment and academic atmosphere for failure tolerance with the help of high-tech modern means. It also needs to improve the academic supervision and evaluation system, strengthen the punishments for academic misconduct and enhance the mentor's exemplary role in education. The eventual goal for our education is to obtain innovative talents who are integrity, respect science and truth, and are good samples for academic performances.

    A novel neutron shielding fibre metal laminates (NSFMLs) with different lay-ups, composed of stacking layers of AA6061 plates, neutron shielding composite and carbon fibre reinforced polyimide (CFRP), were fabricated using hot molding process in atmospheric environments. The microstructure, mechanical properties and neutron transmission of the NSFMLs were evaluated, respectively. The results indicated that the NSFMLs possessed good mechanical properties owing to the good interfacial adhesion of the components. Tensile strength and elastic modulus of the NSFMLs increased with the numbers of lay-ups, while the elongation to fracture exhibited obvious declining tendency. Flexural strength and modulus of the NSFMLs were improved obviously with the increasing of stacking layers. Neutron transmission of the NSFMLs decreased obviously with increasing the number of lay-ups, owing to the increase of "1"0B areal density. Besides, the effect of carbon fibres on the neutron shielding performance of the NSFMLs was also taken into consideration. - Highlights: • A novel neutron shielding fibre metal laminates (NSFMLs) with different lay-ups was successfully fabricated using hot molding process. • Mechanical properties of the NSFMLs were performed in accordance with relative standards. • Neutron transmission of the NSFMLs was conducted according to the testing results. • The effect of carbon fibres on the neutron transmission of the NSFMLs was also investigated.

    Racial and ethnic minorities have disproportionately higher cancer incidence and mortality than their White counterparts. In response to this inequity in cancer prevention and care, community-based lay health advisors (LHAs) may be suited to deliver effective, culturally relevant, quality cancer education, prevention/screening, and early detection services for underserved populations. APPROACH AND STRATEGIES: Consistent with key tenets of community-based participatory research (CBPR), this project engaged community partners to develop and implement a unique LHA training curriculum to address cancer health disparities among medically underserved communities in a tricounty area. Seven phases of curriculum development went into designing a final seven-module LHA curriculum. In keeping with principles of CBPR and community engagement, academic-community partners and LHAs themselves were involved at all phases to ensure the needs of academic and community partners were mutually addressed in development and implementation of the LHA program. Community-based LHA programs for outreach, education, and promotion of cancer screening and early detection, are ideal for addressing cancer health disparities in access and quality care. When community-based LHAs are appropriately recruited, trained, and located in communities, they provide unique opportunities to link, bridge, and facilitate quality cancer education, services, and research.

  7. In search of the cancer candidate: can lay epidemiology help?

    Science.gov (United States)

    Macdonald, Sara; Watt, Graham; Macleod, Una

    2013-05-01

    First published in 1991, the ideas embedded in 'Lay epidemiology and the prevention paradox' offered a novel and rational explanation for the lay public's failure to fully engage with the lifestyle messages offered by health educators. During the course of a large ethnographic study in South Wales, Davison and colleagues described the emergence of what they termed the coronary candidate. Candidacy provides a 'cultural mechanism' that facilitates the estimation of risk for coronary heart disease. The model has rarely been applied to other major illnesses. This article presents findings from a study that sought to explore the lay epidemiology model, candidacy and cancer. In a series of in-depth individual interviews, members of the lay public discussed their ideas about cancer, and what emerged was an explanatory hierarchy to account for cancer events. Yet the random and unpredictable nature of cancer was emphasised as well as a general reluctance to accept the idea of cancer candidacy. © 2012 The Authors.

  8. Coupled dynamic analysis of subsea pipe laying operations

    2009-12-19

    It is recognized that deep water offshore oil exploitation activities requires the use of sophisticated computational tools to predict the behavior of floating offshore systems under the action of environmental loads. These computational tools should be able to perform coupled dynamic analyses, considering the non-linear interaction of the hydrodynamic behavior of the platform with the structural/hydrodynamic behavior of the mooring lines and risers, represented by Finite Element models. The use of such a sophisticated computational tool becomes mandatory not only for the design of production platforms, but also for the simulation of offshore installation operations. For instance, in the installation of submarine pipelines, the wall thickness design may not be governed by the pressure containment requirements of the pipeline during the operation, but by the installation process, specifically the combined action of bending, tension and hydrostatic pressure acting on the pipeline, that is also submitted to the motions of the lay barge. Therefore, the objective of this work is to present the results of numerical simulations of S-lay installation procedures using a computational tool that performs dynamic analysis coupling the structural behavior of the pipe with the hydrodynamic behavior of the vessel motions under environmental conditions. This tool rigorously considers the contact between the pipeline and its supports (lay barge, stinger, seabed). The results are compared to traditional pipe laying simulations based on RAO motions.

    2016-01-01

    Pigs and poultry are by far the most omnivorous of the domesticated farm animals and it is in their nature to be highly explorative. In the barren production environments, this motivation to explore can be expressed as abnormal oral manipulation directed toward pen mates. Tail biting (TB) in pigs and feather pecking (FP) in laying hens are examples of unwanted behaviors that are detrimental to the welfare of the animals. The aim of this review is to draw these two seemingly similar abnormalities together in a common framework, in order to seek underlying mechanisms and principles. Both TB and FP are affected by the physical and social environment, but not all individuals in a group express these behaviors and individual genetic and neurobiological characteristics play an important role. By synthesizing what is known about environmental and individual influences, we suggest a novel possible mechanism, common for pigs and poultry, involving the brain–gut–microbiota axis.

    Traditionally Academics and citizens have contributed to each other lives but friction has always existed between the two. When there is a hostile relationship between community members and Academics, the collection of data suffers, which in returns hurts the potential solutions to community problems. Combining Community Based Participatory Research and the BISCO Community Organizing Model, {Listens, Identify, Research, offer solution}, these frictions can be limited, creating better working environments, and producing better data. Helping create and participating in workgroups, including NGO's, Academics and Citizens leaders, have produce better working environments. Using these methods within the work groups I observed, relationships being form between Academics and Citizens. Some of the relationships were both public and private. The workgroups that created space for professional and personal stories telling produced the most relationships. Listening and understand each other, before research have proven to be successful in producing trust between Academics and Citizens. When Academics and Citizens developed trust between themselves, each party respects the other limitation. Knowing each limitation is perhaps the most key element in working together, which eliminates over promises and culture hindrance within the community. It's amazing like getting the answers to the test before you take it. The project becomes richer in design, when there is trust in the process before it begins. Working together to eliminating potential road blocks ahead of time, enhance the project chances to produce, richer data.Academics cannot produce good data if citizens withhold information and citizens cannot solve their social ills if they do not have good data, in short we need each other.

  18. Lay theories of suicide among Austrian psychology undergraduates.

    Voracek, Martin; Loibl, Lisa Mariella; Lester, David

    2007-01-01

    Lester and Bean's (1992) Attribution of Causes to Suicide Scale gauges lay theories of suicide including intrapsychic problems, interpersonal conflicts, and societal forces as causes. Results obtained with its German form (n=165 Austrian psychology undergraduates) showed no sex differences and no social-desirability effects. Intriguingly, all three subscales were moderately intercorrelated, thereby indicating respondents' general agreement (or disagreement) with all three theories. Thus, the critical dimension of lay theories of suicide appears to be the belief that suicide has definite causes (regardless of type) versus that it is without causes (unpredictable). In addition, religiosity was positively associated (and overall knowledge about suicide negatively associated) with belief in intrapsychic causes, whereas liberal political views were negatively associated with belief in interpersonal causes.

    Full Text Available The teaching of the Second Vatican Council develops an understanding of the Church as an integral entirety, present in the world and operating in accordance with its nature and purpose. Every personal commitment of a lay faithful, every effort made and each achievement has an impact on others and the whole Church. However, the commitment of adult Catholics to the world requires their appropriate preparation. Therefore, this article will first present the ecclesiological foundations of the lay faithful’s earthly commitment, and then, the process of their preparation, taking into consideration their personal and religious development. Finally it will also explore the meaning of the community as the place of their permanent formation.

  1. Nonlinear and hysteretic twisting effects in ocean cable laying

    Armored ocean cable unlays under the action of installation tensions and restraining moments applied by the ocean bottom and the ship's bow sheave. The process of elongation and twist is nonlinear and hysteretic. This process has often been assumed linear and reversible. The equations describing the moment which is developed in laying cable on the ocean bottom are worked out, without assuming linearity and reversibility. These equations are applied to some cases likely to arise. For a typical armored coaxial cable laid in 3700m (2,000 fathoms) depth without bottom tension, a steady-state laying-up moment of 134Nm (99 lbs. ft.) is developed. For the reversible case, no moment is developed. If the bottom tension is increased from zero to 33,375N (7500 lbs.) and then returned to zero, a peak moment of 198Nm (146 lbs. ft.) is developed

    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.

    Investigation into local peoples' perceptions can produce useful information that could be incorporated into the decision-making process to help resolve environmental problems. Within the arena of land degradation, a number of studies have also been conducted to explore local peoples' views of the problem. However, the perceptions of land-degrading practices of the general public have so far not been actively solicited. This study aimed to contribute to this area of research by adopting the psychometric scaling technique to empirically explore the lay public's ecological risk perceptions of land-degrading activities in Minqin County in Gansu Province, northern China. The primary data were collected via a questionnaire survey (n=1,138) administered between 14 and 31 December 2002. The major findings of the survey were: (1) Respondents perceived the ecological risks posed by different land-degrading activities to be different. (2) There was a considerable incongruence in the way in which mining of groundwater was conceived by experts and laymen, respectively. (3) Respondents were pretty unsure of expert knowledge. (4) Respondents' ecological risk perceptions were significantly affected by their personal attributes. As far as the policy implications of these findings are concerned, this study accentuates that we must be aware of, and involved in, the environmental perceptions of the lay public in order to succeed in guiding any human-environment tensions along more sustainable trajectories and navigating the transition to sustainability.

    2006-10-15

    Using the data from the French Environment Barometer EDF-RD 2004 (national representative sample of French citizens aged over 15) and surveys by ADEME between 2000 and 2005, the paper investigates lay perceptions of the causes and consequences of the greenhouse effect, which may be considered as archetypical of contemporary environmental risks. Beyond lay lack of knowledge, the greenhouse effect gives rise to coherent and meaningful cognitions, including causal explanations, shaped by the pre-existing cognitive framework. This cognitive work, based on analogic rather than scientific thought, strings together the greenhouse effect, ozone depletion, air pollution and even nuclear power. The cognitive process is also fed by the individuals' general conceptions of Nature and of the rights and duties of humankind towards Nature. People are not greatly worried about the unseen and controversial consequences of the greenhouse effect: such worry could be one of those 'elite fears' mentioned by Beck. Finally, while the efficiency of public policies to counter the greenhouse effect requires extensive societal involvement, low confidence towards both political and scientific authorities may prevent the population from becoming aware of the environmental stakes tied to the greenhouse effect.

    1. The relationship between the behavioural responses of laying hens to humans and productivity was determined at 16 commercial sheds from 14 farms. 2. A number of behaviour variables were moderately to highly correlated with production variables; for example, the proportion of birds that moved away from an approaching experimenter in an unfamiliar environment ('shute test') was negatively correlated with peak hen day production, (PKHDP). 3. Behavioural responses to humans accounted for between 23 and 63% of the variation in a number of production variables, including PKHDP and the duration of a high level of production. 4. Inclusion of farm factor variables increased the amount of variation accounted for by the behaviour variables. For example, adding the variable 'time/day spent in the shed by stockpeople' to the behaviour variables 'the proportion of birds that moved away from an approaching human' in the shute test and 'the number of times birds in cages adopted an erect posture' in response to an approaching human increased the variation accounted for in PKHDP from 53 to 61%. 5. The results suggest that fear of humans may be a factor that limits the productivity of commercial laying hens.

    Full Text Available The research was aimed to evaluate the performance of laying hens fed different calcium sources. Two hundreds of Isa Brown laying hens were used in this study. The hens were raised in individual battery cages units for 12 weeks. Four calcium source (limestone as a control, 5% limestone + 2.5% eggshells waste, 2.5% limestone + 5% eggshells waste and 7.5% eggshell waste were used in feed experiment. A completely randomized design was applied, with 4 treatments and 5 replications. Each experimental unit consisted of 10 laying hens. The parameters measured were feed intake, protein intake, calcium intake, phosphorus intake, egg production, egg weight and feed conversion ratio. Results of the research showed that the calcium source had significantly effect on performance productions. The use of eggshell waste 7.5% significantly increased the feed intake, calcium intake, phosphorus intake, egg production and egg weight except for feed conversion ratio. The conclusion of this research was that the use of eggshell waste as calcium source of feed resulted in better performance than using limestone or mixed limestone with eggshell waste.

    Full Text Available The use of alternative foods to replace conventional foods is becoming a source of research for many researchers. The cashew nut meal (CNM has high energy and protein value, may be a partial substitute for corn and soybean meal for poultry feed. In this context, this research was conducted to evaluate the effect of inclusion of CNM on the utilization of nutrients in the ration for laying hens, as well as the performance and characteristics of the eggs. The study used 180 Dekalb Brown laying hens 27 weeks of age, distributed in a completely randomized design with six treatments and five replicates of six birds. Treatments consisted of a control diet without CNM and others with the inclusion of this food at levels of 5, 10, 15, 20 and 25%. Upon regression analysis, a linear increase in nitrogen metabolism, crude energy and apparently metabolizable energy was seen. The dry matter digestibility and metabolizable energy corrected for rations were not affected by the inclusion of the CNM. Feed intake and egg weight were not affected by the inclusion of the CNM; however, egg production, egg mass, feed conversion, and yolk color worsened linearly with inclusion of CNM. Compared to control diet, the inclusion of CNM worsened the egg mass and feed conversion from 15%, and yolk color from 20%. As a result, it is recommended the inclusion of the CNM in the diet of laying hens at a maximum level of 10%.

    Lay beliefs about schizophrenia are an important factor associated with treatment-seeking behavior. This study was conducted to investigate the lay beliefs about the causes and treatments of schizophrenia in South Korea. A total of 654 adults (mean age, 35.96 ± 11.33 years) completed two questionnaires assessing their views on the causes and cures of schizophrenia. The factor structures of lay beliefs about the causes and treatments of schizophrenia were then analyzed and the correlations between the resultant factors investigated. From the cause items, four factors were extracted: Health/Lifestyle, God/Fate, Social/Environmental and Biological. Four factors were also extracted from the treatment items: Self-Help/Stress Management, Physical Treatment/Health Management, Religious Help and Mental Health Service Utilization. Notably, most participants believed that items in the Social/Environmental and Biological factors were the causes of schizophrenia, while they believed that items in the Mental Health Service Utilization and Self-Help/Stress Management factors were the treatments. Participants' beliefs about the causes and treatments of schizophrenia were systematically correlated. Overall, laypeople have reasonably accurate beliefs and a multidimensional view of the causes and treatments of schizophrenia. Nevertheless, our results suggest that public education about the etiology and treatment of schizophrenia are necessary to increase actual usage of mental health services and treatments for schizophrenia.

    Full Text Available The objective of this trial was to evaluate the effect of sunflower seed inclusion (0, 1.4, 2.8, 4.2 and 5.6% in a laying hen diet containing corn, soybean meal, wheat meal and soybean oil as main ingredients on performance and egg quality. The evaluated variables were daily feed intake, average egg weight, feed conversion (kg.kg-1 and kg.dz-1, eggshell percentage, yolk color and Haugh unit. One hundred and sixty 25 week-old Lohmann laying hens were used in a completely randomized design with five treatments and four replications of eight birds per experimental unit. Four periods of 28 days were evaluated during 112 days. The inclusion of sunflower seed in the diet had no effect on production parameters during the experimental period. Thus, can be concluded that sunflower seed might be used at concentrations up to 5.6% in laying hen diets without affecting performance and egg quality.

    Three studies were conducted with birds dubbed at hatch vs. dubbed and dewattled at 118 days or 255 to 260 days of age or with normal hens. In the first, involving 5928 pullets of four strains housed 1 per cage, dubbing and dewattling at 255 to 260 days caused small adverse effects on egg numbers as compared with nondubbed controls. Body size was reduced, and both egg weight (EW) and shell strength were increased slightly. In the second study, involving 8180 pullets of nine strains housed 1 per cage, dubbing and dewattling at 118 days slightly increased survivor egg production (SEP) and laying house mortality, and reduced age at first egg, 240-day EW, and 450-day Haugh units (HU), as compared with dubbing only at hatch. There were significant strain by dubbing treatment interactions for hen-day rate of lay (HDR) and SEP. In the third study, involving 1824 pullets of three strain crosses housed 2 and 3 birds per cage (three different cage sizes), there were no significant differences between birds dubbed at hatch and those not dubbed. Variation in age at 50% production, SEP, and HDR was reduced for the dubbed groups. These studies show that the older the birds are when dubbed, the greater the negative effects of dubbing. Hens dubbed at hatch exhibit no effects with the early dubbing or adverse effects in the laying house.

  11. Context-Dependent Plastic Response during Egg-Laying in a Widespread Newt Species.

    Directory of Open Access Journals (Sweden)

    Zoltán Tóth

    Full Text Available Previous research on predator-induced phenotypic plasticity mostly focused on responses in morphology, developmental time and/or behaviour during early life stages, but the potential significance of anticipatory parental responses has been investigated less often. In this study I examined behavioural and maternal responses of gravid female smooth newts, Lissotriton vulgaris, in the presence of chemical cues originating from invertebrate predators, Acilius sulcatus water beetles and Aeshna cyanea dragonfly larvae. More specifically, I tested the extent of oviposition preference, plasticity in egg-wrapping behaviour and plasticity in egg size when females had the possibility to lay eggs at oviposition sites with and without predator cues during overnight trials. I found that individuals did not avoid laying eggs in the environment with predator cues; however, individuals that deposited eggs into both environments adjusted the size of the laid eggs to the perceived environment. Females deposited larger eggs earlier in the season but egg size decreased with time in the absence of predator cues, whereas individuals laid eggs of average size throughout the investigated reproductive period when such cues were present. Also, egg size was found to be positively related to hatching success. Individuals did not adjust their wrapping behaviour to the presence of predator cues, but females differed in the extent of egg-wrapping between ponds. Females' body mass and tail depth were also different between ponds, whereas their body size was positively associated with egg size. According to these results, female smooth newts have the potential to exhibit activational plasticity and invest differently into eggs depending on temporal and environmental factors. Such an anticipatory response may contribute to the success of this caudate species under a wide range of predator regimes at its natural breeding habitats.

    Full Text Available The aim of this study was to monitor the concentration of antibodies against Newcastle disease after vaccination of laying hens at the beginning and in the end of the laying period. The study was carried out in one commercial flock of laying hens in Opatovice in the Czech Republic in the years 2008-2010. A total of 280 samples of blood sera were taken from laying hens coming from four poultry houses. The sera were tested by the haemagglutination inhibition test according to the OIE Manual. Virological testing was conducted as a consequence of atypical results of serological testing. Newcastle disease virus RNA was proved by the RT-nested PCR method in the pooled tissue samples of 5 hens, in the samples of intestines with ileocaecal tonsila, in trachea and also in one swab sample from the environment of one house. Based on sequencing analysis and subsequent phylogenetic analysis, the virus was identified as a low pathogenic strain of paramyxovirus (PMV-1. This low pathogenic strain did not have any impact on the health of laying hens.

    Full Text Available The objective of this study was to estimate the sodium (Na requirements of semi-heavy laying hens reared in a hot climate after peak lay. A total of 120 Hisex Brown hens, 48 weeks of age, were used. The birds were allocated in a completely randomized design consisting of five treatments, six replicates and four animals per experimental unit. The experimental diets were formulated with corn and soybean meal and the treatments consisted of five levels of sodium (0.12, 0.17, 0.22, 0.27 and 0.32% derived from common salt. The following parameters were evaluated: feed intake (g, egg production (%, egg weight (g, egg mass (g, feed conversion (kg per kilogram of eggs and per dozen eggs, specific gravity (g/cm3, shell thickness (mm, egg components including egg yolk (g and %, albumin (g and % and shell (g and %, viability (%, and variation in body weight (g of the birds. There was no effect (P>0.05 of sodium levels on egg yolk weight (g or albumin percentage. A decreasing linear effect (P<0.01 was observed for feed intake, which decreased with increasing sodium level in the diet. A quadratic effect (P<0.05 was found for egg production, egg weight, feed conversion per kilogram of eggs and dozen eggs, albumin and shell weight, specific gravity, shell thickness, and percentage of shell and egg yolk. A sodium level higher than 0.27% negatively influenced egg components and zootechnical performance of the birds. The inclusion of 0.20% sodium in the diet after peak lay is recommended for semi-heavy laying hens reared in a hot climate to increase egg quality and productive performance.

    Full Text Available Egg laying is an important phase of the life cycle of the nematode Caenorhabditis elegans (C. elegans. Previous studies examined egg-laying events manually. This paper presents a method for automatic detection of egg-laying onset using deformable template matching and other morphological image analysis techniques. Some behavioral changes surrounding egg-laying events are also studied. The results demonstrate that the computer vision tools and the algorithm developed here can be effectively used to study C. elegans egg-laying behaviors. The algorithm developed is an essential part of a machine-vision system for C. elegans tracking and behavioral analysis.

    Phytosterols are intended for use as a novel food ingredient with plasma cholesterol-lowering activity. Although phytosterols are naturally present in the normal diet, daily consumption is insufficient to ensure plasma cholesterol-lowering levels. Therefore, phytosterols may be added to the diets to achieve the desired cholesterol-lowering activity. A subchronic laying hen safety study was conducted to examine if high-dose phytosterols could affect the safety of hens. Three hundred sixty 21-wk-old Hy-Line Brown laying hens were randomly assigned to 5 groups with 6 replicates of 12 birds each; after 3 wk, birds were fed diets supplemented with 0, 20, 80, 400, and 800 mg/kg of phytosterols for 12 wk. Throughout the study, clinical observations and laying performance were measured. At the end of the study, birds were subjected to a full postmortem examination: blood samples were taken for clinical pathology, selected organs were weighed, and specified tissues were taken for subsequent histological examination. No treatment-related changes that were considered to be of toxicological significance were observed. Therefore, a nominal phytosterol concentration of 800 mg/kg was considered to be the no-observed-adverse-effect level.

    2009-05-01

    Independent populations subjected to similar environments often exhibit convergent evolution. An unresolved question is the frequency with which such convergence reflects parallel genetic mechanisms. We examined the convergent evolution of egg-laying behavior in the seed-feeding beetle Callosobruchus maculatus. Females avoid ovipositing on seeds bearing conspecific eggs, but the degree of host discrimination varies among geographic populations. In a previous experiment, replicate lines switched from a small host to a large one evolved reduced discrimination after 40 generations. We used line crosses to determine the genetic architecture underlying this rapid response. The most parsimonious genetic models included dominance and/or epistasis for all crosses. The genetic architecture underlying reduced discrimination in two lines was not significantly different from the architecture underlying differences between geographic populations, but the architecture underlying the divergence of a third line differed from all others. We conclude that convergence of this complex trait may in some cases involve parallel genetic mechanisms.

  2. Air Quality in Alternative Housing Systems may have an Impact on Laying Hen Welfare. Part II—Ammonia

    Directory of Open Access Journals (Sweden)

    Bruce David

    2015-09-01

    Full Text Available The EU ban on conventional barren cages for laying hens from 2012 has improved many aspects of laying hen welfare. The new housing systems allow for the expression of highly-motivated behaviors. However, the systems available for intensive large-scale egg production (e.g., aviaries, floor housing systems, furnished cages may cause other welfare challenges. We have reviewed the literature regarding the health, behavior, production characteristics, and welfare of laying hens when exposed to ammonia in their housing environment. Concentrations of ammonia gas are commonly high in aviaries and floor housing systems in which manure is not regularly removed, whereas they are usually lower in furnished cages. High levels are found during the cold season when ventilation flow is often reduced. Ammonia is a pungent gas, and behavioral studies indicate chickens are averse to the gas. High concentrations of gaseous ammonia can have adverse health effects and, when very high, even influence production performance. The most profound effects seen are the occurrence of lesions in the respiratory tract and keratoconjunctivitis. There is also evidence that high ammonia concentrations predispose poultry to respiratory disease and secondary infections. We conclude that there are animal welfare challenges related to high ammonia levels, and that immediate actions are needed. Development of improved systems and management routines for manure removal and ventilation will be important for the reduction of ammonia levels and hence will contribute to safeguarding hen welfare.

    2017-01-01

    This experiment aimed to examine how skill lay-off and system reliability would affect operator behaviour in a simulated work environment under wide-range and large-choice adaptable automation comprising six different levels. Twenty-four participants were tested twice during a 2-hr testing session, with the second session taking place 8 months after the first. In the middle of the second testing session, system reliability changed. The results showed that after the retention interval trust increased and self-confidence decreased. Complacency was unaffected by the lay-off period. Diagnostic speed slowed down after the retention interval but diagnostic accuracy was maintained. No difference between experimental conditions was found for automation management behaviour (i.e. level of automation chosen and frequency of switching between levels). There were few effects of system reliability. Overall, the findings showed that subjective measures were more sensitive to the impact of skill lay-off than objective behavioural measures.

    Full Text Available Feeding management of laying hens has been focused on the direct influence of nutrient intake on weight gain, especially at growing phase. This study evaluates nutrient digestibility, performance, development of the digestive tract, body composition, and bone quality of two strains of laying hens fed with different levels of neutral detergent fiber (NDF during the growing phase from the 7th to the 12th week of age. A total of 1,296 birds were distributed in a completely randomized design in a 2 x 3 factorial arrangement (two strains x three levels of NDF with four replicates of 54 birds per treatment. Semi-heavy (Hy Line Brown and light-strain (Lohman LSL pullets were allotted to dietary treatments consisting of 14.50, 16.50, and 18.50% NDF. An interaction between strains and NDF levels was observed only for feed/gain ratio and light-strain pullets had lower performance with 18.50% NDF. The increasing levels of NDF in the diet reduced the coefficients of digestibility of dry matter, nitrogen and gross energy, and the values of metabolizable energy. Higher levels of NDF in the diet increased the relative weight of liver and intestines and reduced gizzard weight. It was also observed differences between bone quality and composition of the femur and tibia of light and semi-heavy hens. The increase in NDF level in ration for growing phase laying hens above 14.50% decreases the nutrient digestibility and the metabolizable energy of the diet; however, it does not affect the carcass composition, bone quality, feed intake, and weight gain, although it may impair feed conversion of light-strain pullets.

  6. Oramics to electronica: investigating lay understandings of the history of technology through a participatory project

    Directory of Open Access Journals (Sweden)

    Dr Tim Boon

    2014-10-01

    Full Text Available Oramics to Electronica was a 2011 Science Museum project designed to put the tools of museum participation in the service of research into public history, taking the history of electronic music as our example. The primary output was a temporary exhibition. Whereas the term ‘public history’ is often used to denote popularisation of academic history, in this inflection we are primarily concerned with how lay people like our visitors think about the past in general, and about the past of science and technology in particular. Taking the opportunities that arose, we worked with two ‘expert’ groups – of original 1960s participants in electronic music and of 12 recruited present-day music enthusiasts. We also enrolled a group of theatre students and another of writers to respond to the themes of the project and, in particular, to the ‘Oramics Machine’ a unique sound synthesizer created by Daphne Oram. In this essay, an account of our practice is bookended with consideration of related practice and reflections on the implications of the project. It is suggested that the project demonstrated the virtues of proceeding by way of engagement with micro-audiences to understand the ‘cognitive exclusion’ of potential visitors who do not see their interests represented in museum displays.

  8. Reflections on academic video

    Directory of Open Access Journals (Sweden)

    Thommy Eriksson

    2012-11-01

    Full Text Available As academics we study, research and teach audiovisual media, yet rarely disseminate and mediate through it. Today, developments in production technologies have enabled academic researchers to create videos and mediate audiovisually. In academia it is taken for granted that everyone can write a text. Is it now time to assume that everyone can make a video essay? Using the online journal of academic videos Audiovisual Thinking and the videos published in it as a case study, this article seeks to reflect on the emergence and legacy of academic audiovisual dissemination. Anchoring academic video and audiovisual dissemination of knowledge in two critical traditions, documentary theory and semiotics, we will argue that academic video is in fact already present in a variety of academic disciplines, and that academic audiovisual essays are bringing trends and developments that have long been part of academic discourse to their logical conclusion.

  9. Gender-related academic and occupational interests and goals.

    Petersen, Jennifer; Hyde, Janet Shibley

    2014-01-01

    This chapter reviews the theories and empirical evidence concerning whether gender differences in academic and occupational goals and interests exist, and if so, why those differences may be present. Expectancy-value theory, stereotype threat, sociocultural theory, and the gender similarities hypothesis lay the theoretical framework for this chapter. Following a brief review of these theories, we describe the evidence for gender differences in academic ability and occupational interests and goals, using meta-analytic reviews wherever possible. Although there are few gender differences in academic ability, some gender differences in occupational goals and interests persist, particularly in science and mathematics. These gender differences may be due to parental or cultural expectations, changes in developmental trends, stereotypes and discrimination, or gendered-expectations to achieve work-family balance. Overall, the pathways to adult occupations are complex, involving many factors that affect occupational goals, interests, and self-concept.

    The study was conducted to investigate whether high-dose zinc methionine (Zn-Met) affected the safety of laying hens, including laying performance, hematological parameters, serum chemical parameters, organ index, and histopathology. A total of 540 20-week-old Hy-Line White laying hens was randomly allocated to 6 groups with 6 replicates of 15 birds each. Birds were fed diets supplemented with 0 (control), 70, 140, 350, 700, or 1,400 mg Zn/kg diet as Zn-Met. The experiment lasted for 8 wk after a 2-week acclimation period. Results showed that dietary supplementation with 70 or 140 mg Zn/kg diet as Zn-Met significantly increased average daily egg mass (ADEM), laying rate (LR), and feed conversion ratio (FCR) (P hens fed with 0, 350, or 700 mg Zn/kg as Zn-Met (P > 0.05); hens administered 1,400 mg Zn/kg showed a significant increase in BSER and remarkable decreases in ADEM, LR, and FCR (P hens receiving 0, 70, 140, 350, or 700 mg Zn/kg as Zn-Met in serum chemical parameters (P > 0.05); supplementation with 1,400 mg Zn/kg as Zn-Met remarkably elevated the concentrations of serum total bilirubin (TBILI), glucose (GLU), uric acid (UA), and creatinine (CRE) (P hens administered 0, 70, 140, 350, or 700 mg Zn/kg as Zn-Met, while significant histological lesions were observed in the heart, liver, lung, and kidney tissues of hens receiving 1,400 mg Zn/kg as Zn-Met. No significant differences were detected in hematological parameters or organ index (P > 0.05). In conclusion, a nominal Zn concentration of 700 mg/kg as Zn-Met is considered to be no-observed-adverse-effect level following daily administration to hens for 56 days.

    1995-01-01

    Nuclear Power Plant Procedures can be seen from essentially two viewpoints: the process and the information management. From the first point of view, it is important to supply the knowledge apt to solve problems connected with the control of the process, from the second one the focus of attention is on the knowledge representation, its structure, elicitation and maintenance, formal quality assurance. These two aspects of procedure representation can be considered and solved separately. In particular, methodological, formal and management issues require long and tedious activities, that in most cases constitute a great barrier for procedures development and upgrade. To solve these problems, Ansaldo is developing DIAM, a wide integrated tool for procedure management to support in procedure writing, updating, usage and documentation. One of the most challenging features of DIAM is AUTO-LAY, a CASE sub-tool that, in a complete automatical way, structures parts or complete flow diagrams. This is a feature that is partially present in some other CASE products, that, anyway, do not allow complex graph handling and isomorphism between video and paper representation AUTO-LAY has the unique prerogative to draw graphs of any complexity, to section them in pages, and to automatically compose a document. This has been recognized in the literature as the most important second-generation CASE improvement. (author). 5 refs., 9 figs

    Dietary intake of lycopene has been associated with a reduced risk of ovarian cancer, suggesting its chemopreventive potential against ovarian carcinogenesis. Lycopene's molecular mechanisms of action in ovarian cancer have not been fully understood. Therefore, in the present study, we investigated the effects of lycopene on the ovarian cancer formation using the laying hen model, a biologically relevant animal model of spontaneous ovarian carcinogenesis due to high incidence rates similar to humans. In this study, a total of 150 laying hens at age of 102 weeks were randomized into groups of 50: a control group (0 mg of lycopene per kg of diet) and two treatment groups (200 mg or 400 mg of lycopene per kg of diet, or ~26 and 52 mg/d/hen, respectively). At the end of 12 months, blood, ovarian tissues and tumors were collected. We observed that lycopene supplementation significantly reduced the overall ovarian tumor incidence ( P Lycopene also significantly decreased the rate of adenocarcinoma, including serous and mucinous subtypes ( P lycopene-fed hens compared to control birds ( P lycopene reduced the expression of NF-κB while increasing the expression of nuclear factor erythroid 2 and its major target protein, heme oxygenase 1. In addition, lycopene supplementation decreased the expression of STAT3 by inducing the protein inhibitor of activated STAT3 expression in the ovarian tissues. Taken together, our findings strongly support the potential of lycopene in the chemoprevention of ovarian cancer through antioxidant and anti-inflammatory mechanisms.

  15. Egg-laying substrate selection for optimal camouflage by quail.

    2013-02-04

    Camouflage is conferred by background matching and disruption, which are both affected by microhabitat. However, microhabitat selection that enhances camouflage has only been demonstrated in species with discrete phenotypic morphs. For most animals, phenotypic variation is continuous; here we explore whether such individuals can select microhabitats to best exploit camouflage. We use substrate selection in a ground-nesting bird (Japanese quail, Coturnix japonica). For such species, threat from visual predators is high and egg appearance shows strong between-female variation. In quail, variation in appearance is particularly obvious in the amount of dark maculation on the light-colored shell. When given a choice, birds consistently selected laying substrates that made visual detection of their egg outline most challenging. However, the strategy for maximizing camouflage varied with the degree of egg maculation. Females laying heavily maculated eggs selected the substrate that more closely matched egg maculation color properties, leading to camouflage through disruptive coloration. For lightly maculated eggs, females chose a substrate that best matched their egg background coloration, suggesting background matching. Our results show that quail "know" their individual egg patterning and seek out a nest position that provides most effective camouflage for their individual phenotype. Copyright © 2013 Elsevier Ltd.

    Laying hens housed in free-range systems have access to an outdoor range, and individual hens within a flock differ in their ranging behaviour. Whether there is a link between ranging and laying hen welfare remains unclear. We analysed the relationships between ranging by individual hens on a commercial free-range layer farm and behavioural, physiological and health measures of animal welfare. We hypothesised that hens that access the range more will be (1) less fearful in general and in response to novelty and humans, (2) have better health in terms of physical body condition and (3) have a reduced physiological stress response to behavioural tests of fear and health assessments than hens that use the range less. Using radio frequency identification tracking across two flocks, we recorded individual hens' frequency, duration and consistency of ranging. We also assessed how far hens ventured into the range based on three zones: 0 to 2.4, 2.4 to 11.4 or >11.4 m from the shed. We assessed hen welfare using a variety of measures including: tonic immobility, open field, novel object, human approach, and human avoidance (HAV) behavioural tests; stress-induced plasma corticosterone response and faecal glucocorticoid metabolites; live weight, comb colour, and beak, plumage, footpad, and keel bone condition. Range use was positively correlated with plasma corticosterone response, faecal glucocorticoid metabolites, and greater flight distance during HAV. Hens that used the range more, moved towards rather than away from the novel object more often than hens that ranged less. Distance ranged from the shed was significantly associated with comb colour and beak condition, in that hens with darker combs and more intact beaks ranged further. Overall the findings suggest that there is no strong link between outdoor range usage and laying hen welfare. Alternatively, it may be that hens that differed in their ranging behaviour showed few differences in measures of welfare because

    Retention of academic Mohs surgeons is important for the growth of this specialty and teaching of residents and students. To examine factors that influence retention of Mohs surgeons in academics and to better understand reasons for their departure. A survey was electronically distributed to academic Mohs surgeons in the American College of Mohs Surgery, asking them to rate the importance of several variables on their decision to remain in academia. Private practice Mohs surgeons who had left academics were also surveyed. Two hundred thirty-six dermatologic surgeons completed the survey. Twenty-nine percent work full time in academics, and approximately 7% work part time. The top reasons for practicing in the academic setting are intellectual stimulation, teaching opportunities, and collaboration with other university physicians and researchers. Seventy-one percent of respondents reported they would stay in academics, 7% indicated they would not, and 22% were unsure. Unfair compensation, inadequate support staff, poor leadership, increased bureaucracy, and decreased autonomy were top reasons that may compel a Mohs surgeon to leave. Opportunities for intellectual stimulation, collaboration, and teaching remain the main draw for academic Mohs surgeons. A supportive environment, strong leadership, and establishing fair compensation are imperative in ensuring their stay.

    This study investigated the relationship between lay theories of cigarette smoking and expectations to smoke. An incremental lay theory of smoking entails the belief that smoking behavior can change; an entity theory entails the belief that smoking behavior cannot change. Undergraduate nonsmokers and smokers completed a survey that assessed lay theories of smoking and smoking expectations. Results demonstrated that lay theories of smoking were differentially associated with smoking expectations for nonsmokers and smokers: stronger incremental beliefs were associated with greater expectations of trying smoking for nonsmokers but lower expectations of becoming a regular smoker for smokers. Implications for interventions are discussed. © The Author(s) 2013.

  3. Egg-laying butterflies distinguish predaceous ants by sight.

    Sendoya, Sebastián F; Freitas, André V L; Oliveira, Paulo S

    2009-07-01

    Information about predation risks is critical for herbivorous insects, and natural selection favors their ability to detect predators before oviposition and to select enemy-free foliage when offspring mortality risk is high. Food plants are selected by ovipositing butterflies, and offspring survival frequently varies among plants because of variation in the presence of predators. Eunica bechina butterflies oviposit on Caryocar brasiliense, an ant-defended plant. Experiments with dried Camponotus and Cephalotes ants pinned to leaves revealed that butterflies use ant size and form as visual cues to avoid ovipositing on plant parts occupied by ants more likely to kill larval offspring. Presence of sap-sucking bugs did not affect butterfly oviposition. This is the first demonstration that visual recognition of predators can mediate egg-laying decisions by an insect herbivore and that an insect will discriminate among different species of potential predators. This unusual behavioral capability permits specialization on a risky, ant-defended food plant.

Randomized, community-based study comparing In-person or Web-based training, with mailed materials. In-person and Web-training groups had significant post-training cessation knowledge and self-efficacy gains. All groups increased the proportion of individuals reporting BIs at follow-up, with no significant between-group differences. Irrespective of participants' prior intervention experience, 80%-86% reported BIs within the past 90 days; 71%-79% reported >1 in the past 30. Web and In-person training significantly increase health influencer cessation knowledge and self-efficacy. With minimal prompting and materials, even persons without BI experience can be activated to encourage tobacco cessation.

    Full Text Available Egg laying site selection by a host plant specialist leaf miner moth at two intra-plant levels in the northern Chilean Atacama Desert. The spatial distribution of the immature stages of the leaf miner Angelabella tecomae Vargas & Parra, 2005 was determined at two intra-plant levels (shoot and leaflet on the shrub Tecoma fulva fulva (Cav. D. Don (Bignoniaceae in the Azapa valley, northern Chilean Atacama Desert. An aggregated spatial pattern was detected for all the immature stages along the shoot, with an age dependent relative position: eggs and first instar larvae were clumped at apex; second, third and fourth instar larvae were mostly found at intermediate positions; meanwhile the spinning larva and pupa were clumped at basis. This pattern suggests that the females select new, actively growing leaflets for egg laying. At the leaflet level, the immature stages were found more frequently at underside. Furthermore, survivorship was higher for larvae from underside mines. All these results highlight the importance of an accurate selection of egg laying site in the life history of this highly specialized leaf miner. By contrast, eventual wrong choices in the egg laying site selection may be associated with diminished larval survivorship. The importance of the continuous availability of new plant tissue in this highly human modified arid environment is discussed in relation with the observed patterns.

    Purpose Despite recent efforts to understand the complex process of physician career development, the medical education community has a poor understanding of why, how, and when women physicians embark on a career in academic medicine. Method In 2010, the authors phone-interviewed women physicians in academic medicine regarding why, how, and when they chose an academic medicine career. Project investigators first individually and then collectively analyzed transcripts to identify themes in the data. Results Through analyzing the transcripts of the 53 interviews, the investigators identified five themes related to why women choose careers in academic medicine: fit, aspects of the academic health center environment, people, exposure, and clincial medicine. They identified five themes related to how women make the decision to enter academic medicine: change in specialty, dissatisfaction with former career, emotionality, parental influence, and decision-making styles. The authors also identified four themes regarding when women decide to enter academic medicine: as a practicing phyisican, fellow, resident, or medical student. Conclusions Choosing a career in academic medicine is greatly influenced by the environment in which one trains and by people—be they faculty, mentors, role models, or family. An interest in teaching is a primary reason women choose a career in academic medicine. Many women physicians entering acadmic medicine chose this after or during fellowship, which is when they became more aware of academic medicine as a possible career. For many women, choosing academic medicine was not necessarily an active, planned decision; rather it was serendipitous or circumstantial. PMID:22104052

    This study was conducted to evaluate the effects of zinc methionine (Zn-Met) supplementation on the performance, egg quality, antioxidant status and some biochemical parameters of blood serum in laying hens from 22 to 34 weeks of age. A total of 120 Hisex Brown laying hens of 22-week-old were randomly allocated into five treatments with six cage replicates for each (four hens/replicate). Dietary treatments consisted of the basal diet with no Zn-Met supplementation (control group) and basal diet supplemented with 25, 50, 75 or 100 mg Zn-Met/kg diet. No significant differences were observed on body weight, body weight gain or feed conversion ratio due to dietary Zn-Met supplementation. However, highly significant impact was observed on daily feed intake. Egg number, egg weight and egg mass were increased in the group fed diet supplemented with the highest level of Zn-Met (100 mg/kg of diet) as compared to other groups. All egg quality traits were statistically (p > .05 or .01) affected as a response to dietary Zn-Met supplementation except egg shape index, shell percentage and yolk index. In comparison with the control group, dietary supplementation of 25, 50, 75 or 100 mg Zn-Met/kg decreased serum triglyceride and LDL-cholesterol levels. Serum cholesterol level was increased with all dietary levels of Zn-Met in comparison with the control group. Dietary Zn-Met supplementation increased the serum content of zinc, where the highest values were recorded with 50 and 100 mg Zn-Met/kg diet. Dietary Zn-Met levels did not affect the antioxidant indices in blood serum except for the activity of copper-zinc superoxide dismutase (Cu-Zn-SOD). The activity of Cu-Zn-SOD was increased with Zn-Met supplementations with no differences among supplemental zinc levels. It is concluded that dietary Zn-Met supplementation reduced serum triglyceride, LDL-cholesterol and increased Zn status and resulted in promoting antioxidant ability of laying hens, and the addition of 100 mg Zn

    There is a consensus that patients and the public should be involved in research in a meaningful way. However, to date, lay people have been mostly involved in developing research ideas and commenting on patient information.We previously published a paper describing our experience with lay partners conducting observations in a study of how patients in hospital are involved with their medicines. In a later part of the same study, lay partners were also involved in analysing interviews that a researcher had conducted with patients, carers and healthcare professionals about patient and carer involvement with medicines in hospital. We therefore wanted to build on our previous paper and report on our experiences with lay partners helping to conduct data analysis. We therefore interviewed the lay members and researchers involved in the analysis to find out their views.Both lay members and researchers reported that lay partners added value to the study by bringing their own perspectives and identifying further areas for the researcher to look for in the interviews. In this way researchers and lay partners were able to work together to produce a richer analysis than would have been possible from either alone. Background It is recognised that involving lay people in research in a meaningful rather than tokenistic way is both important and challenging. In this paper, we contribute to this debate by describing our experiences of lay involvement in data analysis. Methods We conducted semi-structured interviews with the lay partners and researchers involved in qualitative data analysis in a wider study of inpatient involvement in medication safety. The interviews were transcribed verbatim and coded using open thematic analysis. Results We interviewed three lay partners and the three researchers involved. These interviews demonstrated that the lay members added value to the analysis by bringing their own perspectives; these were systematically integrated into the analysis by the

    Evidence supports the implementation of task shifting to address health worker shortages that are common in resource-limited settings. However, there is need to learn from established programs to identify ways to achieve the strongest, most sustainable impact. This study examined the Botswana lay counselor cadre, a task shifting initiative, to explore effectiveness and contribution to the health workforce. This evaluation used multiple methods, including a desk review, a national lay counselor survey (n = 385; response = 94%), in-depth interviews (n = 79), lay counselors focus group discussions (n = 7), lay counselors observations (n = 25), and client exit interviews (n = 47). Interview and focus group data indicate that lay counselors contribute to essentially all HIV-related programs in Botswana and they conduct the majority of HIV tests and related counseling at public health facilities throughout the country. Interviews showed that the lay counselor cadre is making the workload of more skilled health workers more manageable and increasing HIV acceptance in communities. The average score on a work-related knowledge test was 74.5%. However for 3 questions, less than half answered correctly. During observations, lay counselors demonstrated average competence for most skills assessed and clients (97.9%) were satisfied with services received. From the survey, lay counselors generally reported being comfortable with their duties; however, some reported clinical duties that extended beyond their training and mandate. Multiple factors affecting the performance of the lay counselors were identified, including insufficient resources, such as private counseling space and HIV test kits; and technical, administrative, and supervisory support. Lay counselors are fulfilling an important role in Botswana's healthcare system, serving as the entry point into HIV care, support, and treatment services.

    Osteoporosis in laying hens has been a production and welfare concern for several decades. The objective of this study was to determine whether differing opportunities for exercise during pullet rearing influences long-term bone quality characteristics in end-of-lay hens. A secondary objective was to assess whether differing opportunities for exercise in adult housing systems alters bone quality characteristics in end-of-lay hens. Four flock replicates of 588 Lohmann Selected Leghorn-Lite pullets were reared in either conventional cages (Conv) or an aviary rearing system (Avi) and placed into conventional cages (CC), 30-bird furnished cages (FC-S), or 60-bird furnished cages (FC-L) for adult housing. Wing and leg bones were collected at the end-of-lay to quantify bone composition and strength using quantitative computed tomography and bone breaking strength (BBS). At the end-of-lay, Avi hens had greater total and cortical cross-sectional area (P lay. © The Author 2017. Published by Oxford University Press on behalf of Poultry Science Association.

    A non-profit organization was formed in 2009 by lay citizens of Nagahama, Japan in response to a community-based genome-epidemiologic study, the 'Nagahama Zero(0)-ji Prevention Cohort Project (N0PCP)'. This organization aims to promote health by taking advantage of citizens' social networks. The Ottawa Charter for Health Promotion affirms the importance of creating supportive environments and coordinating social relationships. Supportive environments (infrastructure) and social relationships (resources) work together as aspects of social capital. This study sought to examine the association between self-rated health and social capital, at both individual and neighborhood levels, and to discuss suitable health promotion strategies for local circumstances.A cross-sectional survey was conducted in 2011, using a self-administered postal questionnaire. Social capital indicators included aspects of support in the environment (social support, neighborhood connectedness, informal social controls, neighborhood trust, general trust, and attachment to place) and social relationships (number of activities; participation in neighborhood activities; participation in recreational activities; and social leverage regarding physical health, mental health, and acquisition of health information). Neighborhood-level social capital was calculated as the percentage of individuals in a neighborhood in the 'high social capital' category. At the individual level, participation in recreational activities, high general trust, and discussion regarding mental health problems with family members were associated with self-rated health positively, whereas discussion of mental health problems with acquaintances had a negative correlation. At the neighborhood level, a highly supportive environment did not contribute to good health, whereas aggregated attachment to place had a positive correlation. There were no significant inter-regional health differences.The results of this study suggest that

    A proper lay-up can only be achieved by plant specific lay-up procedures. The lay-up control practices are necessary to prevent corrosion damage during shut down and are an important part of the life extension of a nuclear power plant. EDF operational experience in this area confirms that damage to plant equipment from improper lay-up procedures is a cause of reduced plant reliability and availability and can increase the corrosion products ingress into the SG during start-up. This article presents the EDF lay-up program and the improvement of lay-up practices. It provides information on the lay-up procedures, best practices and recommendations, operating experience, considerations for different durations of outages; the implementation of a preservation working group, the selection of the systems that will be included in the lay-up program and the material damage characterization in some auxiliary systems. Finally, future developments will be presented, such as the development of a 'convective model' to determine air requirements (humidity, flow rate...) and the drying rate to dry a heat exchanger.

    Full Text Available The experiment was done in the experimental station ÚKZÚZ Havlíčkův Brod. There were four experimental groups (N1, N2, N3, N4 of laying hens and weekly laying intensity was observed. Hybrid ISA BROWN was used in the experiment, 405 hens in each group. The laying intensity was observed from the start of laying for 44 weeks. During laying four different diets were fed to laying hens (N1 – control group with fish meal, N2 – control group containing only of plant protein sources, N3 – experimental group with higher content of rapeseed, N4 – experimental group containing treated rapeseed. Yang model was used for the evaluation of laying curves and we found following parameters of the curves:Yang model N1: y = 97.28 * e – 0.004 * t / [1 + e – 2.054 (t – 2.549]\tR2 = 0.97Yang model N2: y = 98.29 * e – 0.006 * t / [1 + e – 2.071 (t – 2.668]\tR2 = 0.96Yang model N3: y = 98.49 * e – 0.005 * t / [1 + e – 1.856 (t – 2.568]\tR2 = 0.97Yang model N4: y = 98.55 * e – 0.005 * t / [1 + e – 2.251 (t – 2.615].\tR2 = 0.97The results document that experimental treatments had small effect on the parameters of laying curves. It means that rapeseed had only small effect on the laying intensity and also the elimination of animal protein from the diet for laying hens had not effect on laying intensity. On the base of our results we estimated the standard equation for evaluation of laying curve:Yang model: y = 98.15 * e – 0.005 * t / [1 + e – 2.058 (t – 2.601].\tR2 = 0.99This equation can be used as standard for evaluation of laying intensity after experimental treatments or for evaluation of laying intensity of different hybrids.

    We analyzed gender disparities in patenting by country, technological area, and type of assignee using the 4.6 million utility patents issued between 1976 and 2013 by the United States Patent and Trade Office (USPTO). Our analyses of fractionalized inventorships demonstrate that women's rate of patenting has increased from 2.7% of total patenting activity to 10.8% over the nearly 40-year period. Our results show that, in every technological area, female patenting is proportionally more likely to occur in academic institutions than in corporate or government environments. However, women's patents have a lower technological impact than that of men, and that gap is wider in the case of academic patents. We also provide evidence that patents to which women--and in particular academic women--contributed are associated with a higher number of International Patent Classification (IPC) codes and co-inventors than men. The policy implications of these disparities and academic setting advantages are discussed.

  5. Assessing Lay Understanding of Common Presentations of Earthquake Hazard Information

    Thompson, K. J.; Krantz, D. H.

    2010-12-01

    The Working Group on California Earthquake Probabilities (WGCEP) includes, in its introduction to earthquake rupture forecast maps, the assertion that "In daily living, people are used to making decisions based on probabilities -- from the flip of a coin (50% probability of heads) to weather forecasts (such as a 30% chance of rain) to the annual chance of being killed by lightning (about 0.0003%)." [3] However, psychology research identifies a large gap between lay and expert perception of risk for various hazards [2], and cognitive psychologists have shown in numerous studies [1,4-6] that people neglect, distort, misjudge, or misuse probabilities, even when given strong guidelines about the meaning of numerical or verbally stated probabilities [7]. The gap between lay and expert use of probability needs to be recognized more clearly by scientific organizations such as WGCEP. This study undertakes to determine how the lay public interprets earthquake hazard information, as presented in graphical map form by the Uniform California Earthquake Rupture Forecast (UCERF), compiled by the WGCEP and other bodies including the USGS and CGS. It also explores alternate ways of presenting hazard data, to determine which presentation format most effectively translates information from scientists to public. Participants both from California and from elsewhere in the United States are included, to determine whether familiarity -- either with the experience of an earthquake, or with the geography of the forecast area -- affects people's ability to interpret an earthquake hazards map. We hope that the comparisons between the interpretations by scientific experts and by different groups of laypeople will both enhance theoretical understanding of factors that affect information transmission and assist bodies such as the WGCEP in their laudable attempts to help people prepare themselves and their communities for possible natural hazards.

    New strategies for HIV testing services (HTS) are needed to achieve UN 90-90-90 targets, including diagnosis of 90% of people living with HIV. Task-sharing HTS to trained lay providers may alleviate health worker shortages and better reach target groups. We conducted a systematic review of studies evaluating HTS by lay providers using rapid diagnostic tests (RDTs). Peer-reviewed articles were included if they compared HTS using RDTs performed by trained lay providers to HTS by health professionals, or to no intervention. We also reviewed data on end-users' values and preferences around lay providers preforming HTS. Searching was conducted through 10 online databases, reviewing reference lists, and contacting experts. Screening and data abstraction were conducted in duplicate using systematic methods. Of 6113 unique citations identified, 5 studies were included in the effectiveness review and 6 in the values and preferences review. One US-based randomized trial found patients' uptake of HTS doubled with lay providers (57% vs. 27%, percent difference: 30, 95% confidence interval: 27-32, p lay providers. Studies from Cambodia, Malawi, and South Africa comparing testing quality between lay providers and laboratory staff found little discordance and high sensitivity and specificity (≥98%). Values and preferences studies generally found support for lay providers conducting HTS, particularly in non-hypothetical scenarios. Based on evidence supporting using trained lay providers, a WHO expert panel recommended lay providers be allowed to conduct HTS using HIV RDTs. Uptake of this recommendation could expand HIV testing to more people globally.

  7. Timing of the calcium intake and effect of calcium deficiency on behaviour and egg laying in captive great tits, Parus major.

    1997-01-01

    The calcium demand of egg-laying birds is much higher than in other vertebrates during reproduction. We showed elsewhere that a low level of calcium availability can greatly affect the eggshell quality and reproduction of free-living passerines. However, there are few data on calcium demand and calcium intake in relation to egg laying and behaviour and egg-laying performance under conditions of calcium shortage in nondomesticated birds. We examined these aspects in an experiment with captive great tits, Parus major, on a diet deficient in calcium, with or without snail shells as an additional calcium source. More than 90% of the calcium intake for egg production took place during the egg-laying period. Females ingested about 1.7 times as much calcium as they deposited in eggshells. Removing the snail shells after the first egg resulted in eggshell defects and interruptions of laying after 1-3 d. Females without snail shells doubled their searching effort and started to burrow in the soil and to eat sand, small stones, and their own eggs. Most calcium was consumed in the evening, probably to supplement the calcium available from the medullary bone with an additional calcium source in the gut during eggshell formation. The results demonstrated that eggshell formation requires accurate timing of the calcium intake and that obtaining sufficient calcium is time-consuming, even in calcium-rich environments. These factors pertaining to calcium intake greatly affect the ability of birds to collect sufficient calcium for eggshell formation in calcium-poor areas.

This tactic transferred to the university level means providing systems to teachers and managers in order to support decision making in their teaching activity (Guitart and Conesa, 2014. Despite the advantages that has led to the use of these systems and the difficulties encountered with treatment and how the data are used to support decisions on the academic level, it has not seen a systematic use of the same. Due to the increased volume of stored data, teachers and administrators face an environment of uncertainty and increasing complexity. Generally it not has the necessary tools to manipulate these data and turn it into valuable information. This study aimed to develop a business based on intelligence that enables capture, store, process, analyze and display efficiently, the data generated in the educational process. The proposal was used with data from the first year of a faculty of the University of Information Science in 2012-2013, 2013-2014 and first semester of courses in 2014 and 2015 from which useful information was obtained for decision making. Finally a set of organizational elements for the proper use of the system was proposed.

    Bird eggs are commonly used in contaminant monitoring programs and toxicological risk assessments, but intraclutch variation and sampling methodology could influence interpretability. The authors examined the influence of egg-laying sequence on egg mercury concentrations and burdens in American avocets, black-necked stilts, and Forster's terns. The average decline in mercury concentrations between the first and last eggs laid was 33% for stilts, 22% for terns, and 11% for avocets, and most of this decline occurred between the first and second eggs laid (24% for stilts, 18% for terns, and 9% for avocets). Trends in egg size with egg-laying order were inconsistent among species, and overall differences in egg volume, mass, length, and width were eggs laid. Despite the strong effect of egg-laying sequence, most of the variance in egg mercury concentrations still occurred among clutches (75-91%) rather than within clutches (9%-25%). Using simulations, the authors determined that accurate estimation of a population's mean egg mercury concentration using only a single random egg from a subset of nests would require sampling >60 nests to represent a large population (10% accuracy) or ≥14 nests to represent a small colony that contained <100 nests (20% accuracy).

    Full Text Available This paper studies the cultural change in science from academic science to post-academic science by the use of documentary studying and analytical reasoning. The aim of this study is determining the direction of cultural change in science and comparing it with cultural change in society.The knowledge production which surrounds academy has little relationship with the values of society and epistemological norms regulate scientists' behavior from within the scientific system. But in post-academic science the relationship between science and society operates in the same line with market and government and science produce within the social context and scientists' behavior controlled by the norms out of the scientific system. So the culture of science has changed because science applied to meet the requirements of market and industry. The result is that contrary to cultural change in society that goes from materialism to post-materialism, cultural change in science moves from post-materialism to materialism.

  13. Performance of Commercial Laying Hen Submitted to Different Debeaking Methods

    Full Text Available ABSTRACT Among the several factors required in breeding laying hens, debeaking is a factor that interferes with batch performance and affects animal welfare. Thus, the objective of this study was to evaluate three different debeaking procedures and to verify the best technique to be used. For this, the performance of the birds, the incidence of cannibalism, and in rearing phase, the quality of the eggs were evaluated. Dekalb White birds were distributed in a completely randomized design with three treatments, T1 (infrared radiation debeaking T2 (hot blade debeaking and T3 (V debeaking.The data was submitted to Analysis of Variance and compared by Tukey’s test (95%, using statistical software R. The frequencies of mortality and cannibalism were submitted to the Chi-Square test (Software R. It was observed that mortality was lower with IR debeaking in the breeding phase. Already in the rearing phase, the mortality was similar between the debeaking techniques and the cannibalism was null. The final mean weight (g, mean weight gain (g and average daily weight gain in the rearing and egg quality variables were higher for V debeaking when compared to other techniques. It is concluded that V-debeaking provides better bird performance, resistance and shell thickness when compared to the infrared radiations and hot blade debeaking, in addition to subjecting the birds to less stress.

    This study examined perceptions of healthy eating styles among US respondents to determine whether eating styles are defined as a distinct set of people's healthy eating beliefs and how different aspects of eating styles are perceived to affect health. In-person pile sort activities were used to identify key dimensions of healthy eating beliefs, and online surveys were used to confirm these dimensions and examine perceived health benefits of healthy eating styles. The pile-sorting activity recruited 48 US participants in the Phoenix metropolitan area via social media and snowball sampling. Online surveys recruited US participants via Amazon Mechanical Turk (survey 1, n = 70; survey 2, n = 283). The researchers used an exploratory visualizing technique (multidimensional scaling) to analyze pile sort data; Property Filling (PROFIT) analysis was used to analyze online survey 1; paired sample t test and repeated-measures ANOVA were used to analyze online survey 2. Eating styles are a distinct set of beliefs within lay models of healthful diets (P management. In addition to educating the public about choosing healthy food characteristics, health and nutrition professionals may need to address people's beliefs regarding healthy eating styles to identify gaps and misconceptions. Future research is needed to examine the relationships between such beliefs and corresponding behaviors, as well as whether these behaviors result in any health benefits.

Methods Nine hundred Longyan ducks aged 17 wk were assigned randomly to the six dietary treatments, where each treatment comprised six replicate pens with 25 ducks per pen. Results Increasing the Thr level enhanced egg production, egg weight, egg mass, and the feed conversion ratio (FCR (linearly or quadratically; p<0.05. The Haugh unit score, yolk color, albumen height, and the weight, percentage, thickness, and breaking strength of the eggshell did not response to increases in the Thr levels, but the albumen weight and its proportion increased significantly (p<0.05, whereas the yolk weight and its proportion decreased significantly as the Thr levels increased. Conclusion According to a regression model, the optimal Thr requirement for egg production, egg mass, and FCR in Longyan ducks is 0.57%, while 0.58% is the optimal level for egg weight from 17 to 45 wk of age.

    Yesterday saw the publication of the latest P5 report in the United States. Shorthand for Particle Physics Project Prioritisation Panel, the P5 report is the US equivalent of the European Strategy update that was published last year, and it’s good to see that the two reports present a common vision of the direction our field should take over the coming years.   P5 was charged with developing a 10-year plan for US particle physics, identifying compelling scientific opportunities. Its approach was similar to the European one, based on a broad consultation among the particle physics community. For the energy frontier, the report is clear. The LHC will be the focus for the US particle physics community for the immediate and short-term future. The report goes on to lay out a bold vision for development of a unique world-class neutrino programme in the US, with the long-term focus being a reformulated Long Baseline Neutrino Facility (LBNF) hosted at Fermilab.

    Declaring and thinking about heroes are common human preoccupations but surprisingly aspects of heroism that reinforce these behaviors are not well-understood. In four thematically consistent studies, we attempt to identify lay perspectives about the psychological functions served by heroes. In Study 1, participants (n = 189) freely generated open-ended descriptions of hero functions, which were then sorted by independent coders into 14 categories (e.g., instill hope, guide others). In Study 2, in an attempt to identify the most important functions associated with heroes, participants (n = 249) rated how each function corresponded with their personal views about heroes. Results from a confirmatory factor analysis suggested that a three-factor model of hero functions fit the data well: participants thought that heroes enhanced the lives of others, promoted morals, and protected individuals from threats. In Study 3 (n = 242), participants rated heroes as more likely to fulfill a protecting function than either leaders or role models. In Studies 4A (n = 38) and 4B (n = 102), participants indicated that thinking about a hero (relative to a leader or an acquaintance) during psychological threat fulfilled personal enhancement, moral modeling, and protection needs. In all, these findings provide an empirical basis to spur additional research about the social and psychological functions that heroes offer.

In Studies 4a (N = 38 and 4b (N = 102, participants indicated that thinking about a hero (relative to a leader or an acquaintance during psychological threat fulfilled personal enhancement, moral modelling, and protection needs. In all, these findings provide an empirical basis to spur additional research about the social and psychological functions that heroes offer.

  19. Lay writings in the debate on nuclear energy in Switzerland

    International Nuclear Information System (INIS)

    Amey, Patrick

    2002-01-01

    The author proposes an analysis of the content of the letters to the editor published in the Swiss press as elements of debate on nuclear energy before voting in 1984 and 1990. He aims at describing how the person who writes this letter and is not an expert in nuclear energy, sets himself as a legitimate interlocutor. Thus he identifies various strategies used by these persons to make their statements with this non-expert posture, or, in other words how these persons proceed to an identity building. He notably identifies different types of lay-person: the self-declared one, the generic or typical one, or the self educated one or autodidact. He outlines how these people quote proverbs or common sayings, refer to a collective identity (by saying we) or to scientific or charismatic persons. He identifies various postures adopted by these persons to appear as non-expert, or as a person belonging to the general public, or how they deal with opposite opinions. In a last part, the author discusses how the acknowledged legitimacy may change from one debate to the other

    Clinical and epidemiological investigations have indicated that there may be substantial human cardiovascular benefits associated with increased consumption of n-3 fatty acids commonly found in fish oils. Recent studies have indicated that egg yolk n-3 fatty acid content is significantly increased when hens are fed diets enriched with selected fish oils such as menhaden oil (MO). In the present study, reproductively active females but not males exhibited increased hepatic lipidosis following 6 mo of feeding 3% MO. Hens fed 3% animal-vegetable oil (AV) did not exhibit hepatic lipid accumulation. Serum triglyceride and cholesterol concentrations were reduced (P < or = .05) in hens fed MO. Subsequently, yolk and total egg weights of hens fed MO were decreased as compared with those of hens fed AV. A significant interaction of dietary MO and exogenous 17 beta-estradiol was noted among chick liver and gallbladder weights. These data suggest that dietary MO and estradiol may interact in a manner that enhances the lipogenic activity of the liver, thereby inducing hepatic lipidosis in laying hens.

    In 1997, a prototype of the LHC dipole magnet, with the two beampipes running through the centre. Even before digging the LEP tunnel, in the early eighties CERN scientists began laying the plans for the second-generation collider to go in the tunnel. From the beginning, physicists had their eyes fixed on certain goals such as finding the Higgs boson and signs of supersymmetric particles. To reach the desired energies within the LEP tunnel, instead of LEP's electrons and positrons, the next collider would need to use more massive particles that radiate away less energy as they travel around the circular tunnel. Also, since the United States was planning the Superconducting Super Collider (SSC) with a circumference even larger than LEP's, CERN scientists conceived of their next collider as a "high-luminosity" machine that would excel at producing a high number of collisions. But since making a strong antiproton beam is laborious, this collider would have to smash together two proton beams. Thus the LHC project ...

    Threonine (Thr) may be a limiting amino acid for laying hens fed diets with lowered protein level. An experiment was conducted to examine laying performance, and the intestinal immune function of laying hens provided diets varying in digestible Thr levels. Lohmann Brown laying hens (n = 480), 28 weeks of age, were allocated to six dietary treatments, each of which included five replicates of 16 hens. Dietary crude protein (CP) 16.18% diet was offered as the positive control diet. L-Thr was added to the negative diet (14.16% CP) by 0, 1.0, 2.0, 3.0 and 4.0 g/kg, corresponding 0.44%, 0.43%, 0.49%, 0.57%, 0.66% and 0.74% digestible Thr. At 40 weeks, a reduction in CP level decreased laying performance (p hens fed 0.66% Thr showed the lowest value (p feed conversion ratio (FCR). Serum level of uric acid showed the lowest values (p hens fed the low-CP diet compared with hens fed CP (16.18%) and hens fed 0.57-0.66%.

    Full Text Available Huoyan goose is a Chinese local breed famous for its higher laying performance, but the problems of variety degeneration have emerged recently, especially a decrease in the number of eggs laid. In order to better understand the molecular mechanism that underlies egg laying in Huoyan geese, gene profiles in the pituitary gland of Huoyan geese taken during the laying period and ceased period were investigated using the suppression subtractive hybridization (SSH method. Total RNA was extracted from pituitary glands of ceased period and laying period geese. The cDNA in the pituitary glands of ceased geese was subtracted from the cDNA in the pituitary glands of laying geese (forward subtraction; the reverse subtraction was also performed. After sequencing and annotation, a total of 30 and 24 up and down-regulated genes were obtained from the forward and reverse SSH libraries, respectively. These genes mostly related to biosynthetic process, cellular nitrogen compound metabolic process, transport, cell differentiation, cellular protein modification process, signal transduction, small molecule metabolic process. Furthermore, eleven genes were selected for further analyses by quantitative real-time PCR (qRT-PCR. The qRT-PCR results for the most part were consistent with the SSH results. Among these genes, Synaptotagmin-1 (SYT1 and Stathmin-2 (STMN2 were substantially over-expressed in laying period compared to ceased period. These results could serve as an important reference for elucidating the molecular mechanism of higher laying performance in Huoyan geese.

    2017-05-01

    Full Text Available From the dawn of Vatican Council II, lay Catholics have been encouraged to actively participate to the life and mission of the Church. Many lay faithful have responded to this call and dispensed their service in various church ministries. However, many other lay men and wo men have not demonstrated a visible participation, especially in the mission of promoting priestly and religious vocations. In its attempt to advocate for a more active collaboration of Vietnamese lay people in vocation promotion, this paper will accomplis h three goals. It will stress once again that lay Christians in Vietnam need to share the responsibility entrusted to each by the Church in encouraging vocations. The paper then argues that lay presence in this ministry enhances its dynamic and effectivene ss. It finally explores ways lay faithful can employ to raise awareness in youth of the call to priesthood and religious life in their context and culture. As such, the study hopes to inspire all baptized to extend their participatory presence in vocation promotion with zeal and confidence.

    Full Text Available The aim of work was to follow up and statistically evaluate the damage and dirty eggs and egg weight, depending on two different breeding systems and different ages of laying hens. Object of investigation were table eggs, their damage and dirty in the laying hens of the final hybrid ISA Brown reared in enriched cage system, and the free range system.  In both rearing systems were ensured the conditions for laying hens in accordance with legislation establishing minimum standards for the laying hens minimum standards for the protection of laying hens, protection of animals kept for farming purposes in accordance with the principles of the so-called five freedoms. That was used to feed a complete feed mixture HYD 10 in both breeding systems. The feeders were supplemented with feed by hand every day and the same day were supplemented water to drinking troughs.  Egg collection was hand in both breeding systems. This paper is a contribution to the solution of optimal breeding hens and production of high quality and safe of table eggs. Based on the results was formulated conclusion, which shows that to the damage and dirty eggs are not affected by the age of the breeding system and age of laying hens. Statistically significant difference     (p ≤ 0.05 in the egg weight was observed between breeding cage system and breeding free range system and   between age 30 and 40 weeks of laying hens.

    Counselling has been identified as a promising strategy to reduce stigma. Lay and peer counsellors have provided counselling in various fields, but this has not yet been studied in the field of leprosy. The Stigma Assessment and Reduction of Impact (SARI) project in Cirebon District, Indonesia took up this endeavour. This paper describes the initial experiences based on the perspectives of the lay and peer counsellors and aims to provide lessons learnt for future initiatives. The selection of lay and peer counsellors was based upon pre-defined criteria such as completed junior high school and level of confidence. This study draws on the notes of seven monitoring and evaluation meetings and 21 group discussions the main researcher facilitated with the lay and peer counsellors and the notes written by the lay and peer counsellors on the sessions with their clients. In total, 198 people affected by leprosy were offered counselling by the 11 lay and 12 peer counsellors; 145 accepted this offer. The other 53 either did not need counselling or did not want to participate for example due to worries about disclosure. Effective communication skills such as listening and asking effective questions were important, but also difficult to acquire for the lay and peer counsellors. Sharing personal experiences was highly appreciated by clients and stimulated a deepened reflection. Challenges related to concealment and effective skills exist, but some people affected by leprosy and others can become effective counsellors making it at the outset a challenging but nevertheless promising intervention.

    2009-01-01

    Full Text Available Abstract Background The husbandry systems for laying hens were changed in Sweden during the years 2001 – 2004, and an increase in the number of submissions for necropsy from laying hen farms was noted. Hence, this study was initiated to compare causes of mortality in different housing systems for commercial laying hens during this change. Methods Based on results from routine necropsies of 914 laying hens performed at the National Veterinary Institute (SVA in Uppsala, Sweden between 2001 and 2004, a retrospective study on the occurrence of diseases and cannibalism, i.e., pecking leading to mortality, in different housing systems was carried out. Using the number of disease outbreaks in caged flocks as the baseline, the expected number of flocks with a certain category of disease in the other housing systems was estimated having regard to the total number of birds in the population. Whether the actual number of flocks significantly exceeded the expected number was determined using a Poisson distribution for the variance of the baseline number, a continuity correction and the exact value for the Poisson distribution function in Excel 2000. Results Common causes of mortality in necropsied laying hens included colibacillosis, erysipelas, coccidiosis, red mite infestation, lymphoid leukosis and cannibalism. Less common diagnoses were Newcastle Disease, pasteurellosis and botulism. Considering the size of the populations in the different housing systems, a larger proportion of laying hens than expected was submitted for necropsy from litter-based systems and free range production compared to hens in cages (P P P Conclusion The results of the present study indicated that during 2001–2004 laying hens housed in litter-based housing systems, with or without access to outdoor areas, were at higher risk of infectious diseases and cannibalistic behaviour compared to laying hens in cages. Future research should focus on finding suitable prophylactic

    The use of lay people to deliver education programmes for people with chronic conditions is a potential method of addressing healthcare staff capacity and increasing the cost efficiency of delivering education. This qualitative substudy is embedded within an equivalence trial (2008-2011 including development stage). In the qualitative substudy, we aimed to elicit the views of key stakeholders (patients, educators) about using lay people to deliver education to people recently diagnosed with type 2 diabetes, alongside a healthcare professional educator with an equal role. In this way, we sought to explore perceptions about acceptability and also contribute to understanding the reasons underlying positive or negative quantitative findings from main trial. We conducted 27 telephone interviews with a purposive sample of patients, lay educators and healthcare professional educators involved in the main trial. Thematic analysis of transcribed data was underpinned by the constant comparative approach and structured using Framework methodology. Overall, the data suggested that the use of lay educators was acceptable to educators and patients. Perceived difference in knowledge levels between lay and healthcare professional educators did not appear to have an impact on perceived acceptability or the effectiveness of the education received. Additional themes explored were related to peer status of educators and feasibility. Some concerns were raised about lay educators with diabetes, transferring personal issues and about the impact of healthcare professional time taken up by mentoring and supporting lay educators. Positive perceptions about the use of lay educators support the positive quantitative findings from the main trial. Acceptability is an important consideration in relation to implementation of the model of delivery studied. Concerns raised within the interviews should be considered in the design of training for lay educators. ISRCTN 99350009. Published by the BMJ

  3. Arrested embryonic development: a review of strategies to delay hatching in egg-laying reptiles

    Rafferty, Anthony R.; Reina, Richard D.

    2012-01-01

    Arrested embryonic development involves the downregulation or cessation of active cell division and metabolic activity, and the capability of an animal to arrest embryonic development results in temporal plasticity of the duration of embryonic period. Arrested embryonic development is an important reproductive strategy for egg-laying animals that provide no parental care after oviposition. In this review, we discuss each type of embryonic developmental arrest used by oviparous reptiles. Environmental pressures that might have directed the evolution of arrest are addressed and we present previously undiscussed environmentally dependent physiological processes that may occur in the egg to bring about arrest. Areas for future research are proposed to clarify how ecology affects the phenotype of developing embryos. We hypothesize that oviparous reptilian mothers are capable of providing their embryos with a level of phenotypic adaptation to local environmental conditions by incorporating maternal factors into the internal environment of the egg that result in different levels of developmental sensitivity to environmental conditions after they are laid.

    2018-03-01

    Full Text Available This study designed a radio-frequency identification (RFID-based Internet of Things (IoT platform to create the core of a smart nest box. At the sensing level, we have deployed RFID-based sensors and egg detection sensors. A low-frequency RFID reader is installed in the bottom of the nest box and a foot ring RFID tag is worn on the leg of individual hens. The RFID-based sensors detect when a hen enters or exits the nest box. The egg-detection sensors are implemented with a resistance strain gauge pressure sensor, which weights the egg in the egg-collection tube. Thus, the smart nest box makes it possible to analyze the laying performance and behavior of individual hens. An evaluative experiment was performed using an enriched cage, a smart nest box, web camera, and monitoring console. The hens were allowed 14 days to become accustomed to the experimental environment before monitoring began. The proposed IoT platform makes it possible to analyze the egg yield of individual hens in real time, thereby enabling the replacement of hens with egg yield below a pre-defined level in order to meet the overall target egg yield rate. The results of this experiment demonstrate the efficacy of the proposed RFID-based smart nest box in monitoring the egg yield and laying behavior of individual hens.

    Full Text Available Introduction Apple is one of the most important fruits that is produced in the large amount in Iran. It is a good source of vitamins and minerals and active fiber. Most of the apples that product in Iran are use in food industry for producing different kinds of apple juices. After Juicing, more than 20% of apple, remain as waste. The remained matter contain considerable amount of vitamins and minerals that usually found in fresh apple, moreover it is rich source of pectin and crude fiber. Generally this byproduct discharge to environment and cause some serious environmental problems. It is thought that use of apple pulp as a part of apple waste in laying hens diets not only prevent some environmental problems, but also can improve their performance, egg quality traits, and blood biochemical parameters and reduce the production cost. The current study has been designed to investigate these traits. Materials and Methods This experiment was carried out on 192 Hi-line (W36 laying hens in a completely randomized design as (2*2 factorial arrangement with two levels of apple pulp (0 and 4% and two levels of probiotic (protexin (0 and 0.005% in 4 treatments, 4 replicates and 12 birds per replicate for 12 weeks (65-76 weeks. Results and Discussion Using apple pulp and probiotic in diets improved the egg production performance, egg quality traits and blood parameters of laying hens (P0.05. Probiotic improved egg weight, egg production percentage, egg mass, feed conversion ratio and Haugh unit. In interaction effects, using apple pulp and probiotic improved the performance and egg quality traits of laying hens. The highest egg weight, egg production, egg mass and the best feed conversion were obtained with diet containing 4% apple pulp and 0.005% probiotic. Also the highest amount of albumin, eggshell thickness and Haugh unit were observed with 4% apple pulp and 0.05% probiotic. Apple pulp decreased the blood levels of triglyceride, cholesterol and albumin

    Full Text Available With rising public concern for animal welfare, many major food chains and restaurants are changing their policies, strictly buying their eggs from non-cage producers. However, with the additional space in these cage-free systems to perform natural behaviours and movements comes the risk of injury. We evaluated the ability to maintain balance in adult laying hens with health problems (footpad dermatitis, keel damage, poor wing feather cover; n = 15 using a series of environmental challenges and compared such abilities with those of healthy birds (n = 5. Environmental challenges consisted of visual and spatial constraints, created using a head mask, perch obstacles, and static and swaying perch states. We hypothesized that perch movement, environmental challenges, and diminished physical health would negatively impact perching performance demonstrated as balance (as measured by time spent on perch and by number of falls of the perch and would require more exaggerated correctional movements. We measured perching stability whereby each bird underwent eight 30-second trials on a static and swaying perch: with and without disrupted vision (head mask, with and without space limitations (obstacles and combinations thereof. Video recordings (600 Hz and a three-axis accelerometer/gyroscope (100 Hz were used to measure the number of jumps/falls, latencies to leave the perch, as well as magnitude and direction of both linear and rotational balance-correcting movements. Laying hens with and without physical health problems, in both challenged and unchallenged environments, managed to perch and remain off the ground. We attribute this capacity to our training of the birds. Environmental challenges and physical state had an effect on the use of accelerations and rotations to stabilize themselves on a perch. Birds with physical health problems performed a higher frequency of rotational corrections to keep the body centered over the perch, whereas, for both

Laying hens with and without physical health problems, in both challenged and unchallenged environments, managed to perch and remain off the ground. We attribute this capacity to our training of the birds. Environmental challenges and physical state had an effect on the use of accelerations and rotations to stabilize themselves on a perch. Birds with physical health problems performed a higher frequency of rotational corrections to keep the body centered over the perch, whereas, for both health categories

    The purpose of this study was to consider the influence of simple and cheap environmental enrichment such as porous concrete on the behavior of laying hens in conventional cages. Forty brown laying hens were housed in individual wire mesh cages: 20 in experimental cages with porous concrete block provided for pecking and 20 in a control group without concrete block provided. Porous concrete block (5 cm length x 5 cm width x 5 cm height) was mounted on the side wall at the height of the hen's head. Behavior was studied from 42 to 48 wk of age. A group of 8 hens was filmed for 24 h, and the camera was moved each day so that all 40 hens were recorded over 5 d each wk. Videotaping was performed in wk 1, 3, 5, and 7 of the experiment. States (long-term behavior) were observed with 5-min interval recording (feeding, preening, resting, and remaining inactive), whereas events (short-term activities) were observed with instantaneous recording (drinking, pecking concrete, pecking neighbors, pecking cage, and attempting to escape). Data were analyzed with generalized linear mixed model with binomial distribution for states, and Poisson distribution for events. Monte Carlo Markov Chain methods were used to estimate model parameters. Because posterior distributions of quantities of interest were skewed, medians and standard errors are reported. Hens in experimental cages were more active in long-term behavior than controls (64.9 +/- 1.9 and 59.3 +/- 1.9% of the light period, respectively). Correspondingly, hens in the control group showed more long-term inactivity. In addition to pecking the porous concrete block, hens in experimental cages also showed other short-term activities with greater frequency (4.10 +/- 0.31 and 3.51 +/- 0.25 events per h, respectively). Our hypothesis that hens in enriched cages would have a greater level of activity was confirmed. Provision of a piece of porous concrete block as a pecking substrate enriched the environment of the birds at negligible

    The effects of stocking density on the performance, egg quality, leukocyte concentration, blood biochemistry, corticosterone levels, bone mineral density, and noxious gas emission of laying hens were investigated. Eight hundred 34-week-old Hy-Line Brown laying hens (Gallus gallus domesticus) were randomly assigned to one of 4 treatments, each of which was replicated 4 times. Four stocking densities, including 5, 6, 7, and 10 birds/m2, were compared. A commercial-type basal diet was formulated to meet or exceed nutrient recommendations for laying hens from the National Research Council. The diet was fed to the hens ad libitum for 8 wk. Results indicated that hen-day egg production, egg mass, and feed intake were less for (P hens. PMID:27578881

    Full Text Available The mission is generic expression of reason for the existence of an organization. Organizational mission ensure continuity of existence beyond the objectives and targets of activities. It is the expression of an organization's responsibilities towards the environment in which it belongs. As the organization grows and its activities or environmental conditions change, managers adapt their strategies, but stated mission will remain valid for a period of time or unchanged throughout the life of the organization. All managerial elements of the organization are aligned with stated mission, starting from the organization structure, management behavior or specific business processes. The focus of the mission of an higher education institution on a need or several integrated needs, on customers who manifest this need and on how they can be met, that really means defining of its strategic domanin, as a sphere of influence of the organization in their environment. In this sphere of influence, three components integrate on three levels of the mission: to establish needs; identify the customer type to which an organization adress and key competencies that differentiate it from the rest competitors. To that context identifies four specific forms of academic institutions starting from their mission and strategic area: autocratic academic institutions, meritocrate academic institutions, democratic academic institutions, bureaucrats academic institutions.

    Immigration to the United States presents both challenges and opportunities that affect students' academic achievement. Using a 5-year longitudinal, mixed-methods approach, we identified varying academic trajectories of newcomer immigrant students from Central America, China, the Dominican Republic, Haiti, and Mexico. Latent class growth curve analysis revealed that although some newcomer students performed at high or improving levels over time, others showed diminishing performance. Multinomial logistic regressions identified significant group differences in academic trajectories, particularly between the high-achieving youth and the other groups. In keeping with ecological-developmental and stage-environment fit theories, School Characteristics (school segregation rate, school poverty rate, and student perceptions of school violence), Family Characteristics (maternal education, parental employment, and household structure), and Individual Characteristics (academic English proficiency, academic engagement, psychological symptoms, gender, and 2 age-related risk factors, number of school transitions and being overaged for grade placement) were associated with different trajectories of academic performance. A series of case studies triangulate many of the quantitative findings as well as illuminate patterns that were not detected in the quantitative data. Thus, the mixed-methods approach sheds light on the cumulative developmental challenges that immigrant students face as they adjust to their new educational settings. 2010 APA, all rights reserved

    We studied the process of offspring production in queenless colonies of Acromyrmex subterraneus brunneus, and particularly evaluated the ovary development of workers as a function of their age. For this, subcolonies were set up and evaluated at different periods of isolation from the queen (2, 4 and 6 months), besides individually labeled age groups. The subcolonies were assessed according to offspring production and ovaries containing oocytes or not. The evaluations showed worker oviposition and development of males originating from worker-laid eggs. At 2 months' absence ofthe queen, eggs and larvae were found, with eggs in a higher proportion than larvae. After 4 months, the proportion of eggs had reduced while larvae had increased, and a pupa was found in one subcolony. At 6 months, besides a higher share of larvae, one pupa and one adult male were found. Dissection of workers revealed ovaries containing oocytes during the periods of evaluation. Only a group of medium-sized and large workers, 23.3%, 20.9% and 37.5% of the population from each period assessed in queenless subcolonies respectively, presented developed oocytes in the ovary. The same was observed in colonies with a queen, with 17.6%, 19.6% and 7.8% of the group of dissected workers from each time period, respectively. With respect to worker age, we observed by dissection of the ovary, that the greatest percentage of individuals with ovarioles containing oocytes occurred at 45 days (6 weeks) up to 90 days (12 weeks). These results probably are associated with the workers reproduction and the laying of trophic and reproductive eggs in colonies with and without a queen; these eggs have distinct functions in each situation.

  17. 'The Lay of the Trilobite': Rereading May Kendall

    Full Text Available The impact of Darwin theory of evolution by natural selection on the culture of late Victorian England and on the development of Western thought at large is at once widely acknowledged and hotly contested. In this essay, I revisit the question of what difference an understanding of Darwin’s ideas, their reception and their afterlife within evolutionary biology makes to how we read Victorian poetry. I suggest that there are three distinct ways of approaching poetry after Darwin. The first is to examine poems in their own cultural context, considering how they respond to the scientific discourses of their time in the light of internal and external evidence as to the specific sources of each poet's knowledge of those discourses. The second is to ground an interpretative framework in Darwinism’s insights into human biology itself. The third is to explore how a given poem’s responses to the philosophical issues raised by Darwin’s thinking, including questions of ethics and theology, give its readers a possible model for their own responses to the same concerns today. I suggest too that the limitations of each approach may be best overcome by bringing them together. I go on to explore the potential of the first and third approaches through a reading of May Kendall’s poem ‘The Lay of the Trilobite’ in a series of different contexts, from its first appearance in ‘Punch’, through her first collection 'Dreams to Sell', to her essays on Christian ethics from the 1880s and 1890s.

    To determine allergenic food proteins, one of the most used tests is the immunoassays such as ELISA (enzyme linked immunosorbent assay), where the antibody recognizes the antigen and this connection is showed by an enzymatic system, in other words, optical density. The aim of this study was to determine the polyclonal antibody efficiency, produced in laboratory, to identify the presence the ovomucoid antigen in treated eggs by gamma irradiation for its inactivation. To evaluate the treatments, polyclonal antibody was produced in female rabbits immunized with bioconjugated ovomucoid. Was used Freund Complete Adjuvant at first immunization and PBS Buffer at four subsequently immunizations every fifteen days, plus a booster 48 hours before the blood retreated. The blood serum was tittered by PTA-ELISA (Plate trapped antigen). All procedures were according to European Norms for ethical and animal welfare. It was used, in nature, commercial laying eggs. So the samples were submitted to the gamma radiation coming from a source of Co 60 , type Multipurpose, under a dose rate of 19.4 and 31.8 Gy/hour, in the doses: 0 (control); 10 KGy; 20 KGy and 30 KGy, in all rates. By the ELISA.s test we can find the egg allergen ovomucoid and the radiation treatment do not showed considerable changes. So we can concluded that the antibody produced is capable of identify the ovomucoid allergenic protein and the gamma irradiation in such rates does not shows changes in that protein, therefore showed some changes in the color and visual viscosity of the egg samples.

    Hospital Information Systems (HIS) are used for easy access to information, improvement of documentation and reducing errors. Nonetheless, using these systems is faced with some barriers and obstacles. This study identifies the challenges and the obstacles of using these systems in the academic and non-academic hospitals in Kerman. This is a cross-sectional study which was carried out in 2015. The statistical population in this study consisted of the nurses who had been working in the academic and non-academic hospitals in Kerman. A questionnaire consisting of two sections was used. The first section consisted of the demographic information of the participants and the second section comprised 34 questions about the challenges of HIS use. Data were analyzed by the descriptive and statistical analysis (t-test, and ANOVA) using SPSS 19 software. The most common and important challenges in the academic hospitals were about human environment factors, particularly "negative attitude of society toward using HIS". In the non-academic hospitals, the most common and important challenges were related to human factors, and among them, "no incentive to use system" was the main factor. The results of the t-test method revealed that there was a significant relationship between gender and the mean score of challenges related to the organizational environment category in the academic hospitals and between familiarity with HIS and mean score of human environment factors (pinformation systems are the factors related to the human environment and the human factors. The results of this study can bring a good perspective to the policy makers and the managers regarding obstacles of using HISs from the nurses' perspective, so that they can solve their problems and can successfully implement these systems.

  3. The academic radiography workforce: Age profile, succession planning and academic development

    Introduction: Academia is one area of practice in which radiographers can specialise; they compile approximately 2% of the total radiography profession in the UK, but are highly influential and essential for the education and development of the workforce in addition to undertaking research. However, the academic environment is very different to clinical practice and a period of transition is required. Methods: Data were collated to explore the age and retirement profile of the academic radiography workforce in the UK; to understand the research time allocated to this workforce; the time required to develop a clinical radiographer into an academic and the mentorship and succession planning provisions nationally. An online UK wide survey was conducted and sent to all 24 Universities delivering radiography education within the UK. Results: Eighteen out of 24 Universities in the UK responded to the survey. Approximately 30% of radiography academics are due to retire over the next 10 years, with over 25% of radiographers who currently hold a doctorate qualification included within this figure. Those entering academia have notably lower qualifications as a group than those who are due to retire. Developing clinical radiographers into academics was thought to take 1–3 years on average, or longer if they are required to undertake research. Conclusion: There is vulnerability in the academic radiography workforce. Higher education institutions need to invest in developing the academic workforce to maintain research and educational expertise, which is underpinned by master's and doctorate level qualifications. - Highlights: • Approximately 30% of radiography academics are due to retire over the next 10 years. • Over 25% of radiographers who currently hold a doctorate qualification included due to retire within 10 years. • Those entering academia have significantly lower qualifications as a group than those who are due to retire. • There is vulnerability in the

  4. The academic prince.

    McGregor, Maurice

    2002-12-01

    The author presents advice to deans and chairs of academia by imagining what Machiavelli might recommend were he to write a modern version of The Prince for academics. "Machiavelli" cautions that since modern academic "princes" have little power (except, perhaps, over teaching and laboratory space), the success of their rule depends upon respect. Regarding the choice of an academic prince, find someone who can be a good role model, set standards, and reward academic excellence, and who will, above all, be respected. Avoid choosing a prince who is a nice, nonthreatening candidate with "good human relations" and "good executive skills." Choose candidates who are already successful and fulfilled and who will see the new post not as a promotion or a balm for their insecurity, but as an intrusion into their academic lives. Fill empty positions as quickly as possible-better a weak prince than no prince at all. Seek short terms for princes, both because respected academics will want to return to their normal lives as soon as possible, and because with short mandates, greater chances can be taken with young, unproved, but promising candidates. At the same time, the appointment of aging administrators who have lost their academic skills is to be avoided. Above all, respect the throne-i.e., the position of chair or dean-even if the person holding the position may not deserve the respect, since when the prince retires with honor, the position becomes more attractive to future good candidates.

    Full Text Available Despite the increase in Latin America of Higher Education coverage, grave dropout problems persist that question the role of educational experiences to foster students’ academic engagement. This study was carried out in Colombia and sought to establish the relationship between the five benchmarks that compose academic engagement and the academic performance of a group of Colombian university students. The transversal and correlational study used the Spanish version of the National Survey of Student Engagement (NSSE that measures students’ level of participation in five dimensions: Academic challenge, active and collaborative learning, student-faculty interaction, enriching educational experiences, and supportive campus environment and its relationship to academic performance. The findings of 1906 students from 7 universities indicate that there are statistically significant, but weak correlations between the items that compose the benchmarks and students’ academic performance, which lead to reflect upon key aspects to strengthen the education experiences offered to university students.

    This paper introduces adult basic life support (BLS) guidelines for lay rescuers of the resuscitation council of Asia (RCA) developed for the first time. The RCA BLS guidelines for lay rescuers have been established by expert consensus among BLS Guidelines Taskforce of the RCA on the basis of the 2015 International Consensus on Cardiopulmonary Resuscitation (CPR) and Emergency Cardiovascular Care Science with Treatment Recommendations. The RCA recommends compression-only CPR for lay rescuers and emphasizes high-quality CPR with chest compression depth of approximately 5cm and chest compression rate of 100-120min(-1). Role of emergency medical dispatchers in helping lay rescuers recognize cardiac arrest and perform CPR is also emphasized. The RCA guidelines will contribute to help Asian countries establish and implement their own CPR guidelines in the context of their domestic circumstances. Copyright © 2016 Elsevier Ireland Ltd.

    Promoting wellness and providing reliable health information in the community present serious challenges. Lay health educators, also known as community health workers, may offer a cost-effective solution to such challenges. This is a retrospective observational study of graduates from the Lay Health Educator Program (LHEP) at Johns Hopkins Bayview Medical Center from 2013 to 2014. Students were enrolled from the surrounding community congregations and from the hospital's accredited clinical pastoral education program. There were 50 events implemented by the lay health educators during the 2014-2015 time period, reaching a total of 2004 individuals. The mean time from date of graduation from the LHEP to implementation of their first health promotional event was 196 ± 76 days. A significant number of lay health educators implemented events within the first year after completing their training. Ongoing monitoring of their community activity and the clinical impact of their efforts should be a priority for future studies.

    Full Text Available The aim of work was to follow up and statistically evaluate the selected quality indicators of egg shell according to two different breeding systems and different age of laying hens. An object of investigation were shell weight, share of the shell, strength and thickness of the shell for table eggs. There were used the laying hens of final hybrid ISA Brown reared in enriched cage system, and free range system. In both breeding systems were ensured the conditions with application of the welfare principles. There was used to feed a complete feed mixture HYD 10 in the both breeding systems.  The feeders were supplemented with feed by hand, daily and the same day was supplemented water to drinking troughs. Egg collection was hand in both breeding systems. This paper is a contribution to the solution of optimal breeding laying hens and production of high quality and safe production of table eggs. From the evaluation of the results was formulated conclusion, which shows that statistically significant (p ≤ 0.05 higher egg shell thickness was observed in the breeding free range system compared to the thickness of the egg shell in the breeding cage system, and in age 40 weeks of laying hens in both breeding systems compared to the thickness of the egg shell in age 30 weeks of laying hens. No statistically significant difference (p ≥ 0.05 was observed in egg shell weight between breeding cage system and free range system. Statistically significant (p ≤ 0.05 higher egg shell weight was observed in the age 40 weeks of laying hens in both breeding  systems compared to age 30 weeks of laying hens. There no statistically significant difference (p ≥ 0.05 was observed in the share of egg shell and egg shell strength between breeding cage system and free range system, nor between age 30 and 40 weeks of laying hens.

    2011-12-01

    In primary care, leaflets are often used to communicate health information. Increasingly, primary healthcare practitioners need to provide dietary advice. There is limited research exploring how nutrition information leaflets are used in primary care. The present study explored practitioner and lay experiences with respect to providing and receiving nutrition information in primary care, focusing in particular on the use of leaflets for nutrition information. A qualitative design was used incorporating focus groups with 57 practitioners based at seven general practitioner practices and a purposive sample of 30 lay participants attending six Consumer Health Organisations within one primary care trust. Focus groups were taped and transcribed verbatim and data were analysed thematically, assisted by computer software n6® (QSR International Pty Ltd, Melbourne, Australia). Practitioners discussed barriers to giving nutritional advice, access to leaflets, lay receptiveness to advice and their perceptions about the value of leaflets to lay people. Food was not considered in terms of its nutritional components by lay participants and the need for nutritional information was not perceived to be relevant until they had received a medical diagnosis. Lay participants discussed the importance of receiving nutritional advice relating to their medical diagnosis and the altered status of written information that was delivered personally. Practitioner and lay groups suggested improvements to ensure that nutritional advice be supported by relevant and appropriate written information. This research has underlined the continuing importance of nutrition information leaflets and concludes that there is particular value in involving lay participants in the development of nutrition information leaflets. © 2011 The Authors.

    The effect of volunteer lay leaders on availability and sustainability of strength-training programs for older adults has not been well explored. We describe implementation of the StrongWomen strength training program by the Arkansas Cooperative Extension Service, and report on the relationship between delivery approach (agent-led, lay-led, or combination of agent- and lay-led) and program access and sustainability. All state Extension agents (n = 66) were surveyed on program implementation, continuance, and use of lay leaders. Program records were used to identify the number of trained lay leaders. Regression models were used to examine the relationship between delivery approach and group availability. Counties using lay leaders had twice as many groups as counties using only agents. There was a significant, positive relationship between the number of lay leaders and the number of groups. Counties using lay leaders were 8.3 times more likely to have continuing groups compared with counties not using lay leaders. Program continuance was significantly and positively associated with lay leader use. Lay delivery expanded access to strength training programs and increased the likelihood that programs would continue. This approach can be used to increase access to and sustainability of strength training programs, particularly in resource-constrained areas.

  3. Machiavellian Ways to Academic Cheating: A Mediational and Interactional Model

    2018-05-01

    Full Text Available Academic cheating has become a pervasive practice from primary schools to university. This study aims at investigating this phenomenon through a nomological network which integrates different theoretical frameworks and models, such as trait and social-cognitive theories and models regarding the approaches to learning and contextual/normative environment. Results on a sample of more than 200 Italian university students show that the Amoral Manipulation facet of Machiavellianism, Academic Moral Disengagement, Deep Approach to Learning, and Normative Academic Cheating are significantly associated with Individual Academic Cheating. Moreover, results show a significant latent interaction effect between Normative Academic Cheating and Amoral Manipulation Machiavellianism: “amoral Machiavellians” students are more prone to resort to Academic Cheating in contexts where Academic Cheating is adopted as a practice by their peers, while this effect is not significant in contexts where Academic Cheating is not normative. Results also show that Academic Moral Disengagement and Deep Approach to learning partially mediate the relationship between Amoral Manipulation and Academic Cheating. Practical implications of these results are discussed.

    Borelli, A.; Perinet, D. [ETPM International (International organizations without location)

    1997-05-01

    The aim of this paper is to study the evolution of conventional pipeline laying barges. The past and todays capacities of some barges are presented in order to follow the evolution of their equipments with time to answer the market needs. The second part outlines the main characteristics of todays market needs. Different analyses are made according to the different means of pipeline laying: conventional, flexible pipes and rigid pipes using unrolling technique. Market trends in these 3 domains show a sensible growth from 1996 to 1997 and are assumed to keep a sustained level during the following years. However, the tendency shows an evolution towards smaller diameter pipes and greater depths. The last part concerns the evolution of laying barges. The most important improvements in pipeline laying industry concern the dynamic positioning, the laying techniques (`S` laying technique), and the rate of laying using real-time control techniques.

    Full Text Available The development of selected haematological and biochemical parameters during the laying period was monitored in common pheasant hens housed in an enhanced cage system. The cages were enhanced by the addition of two perches and a shelter formed by strips of cloth hanging in the corner of the cage. The results showed significant changes in the haematological and biochemical parameters monitored during egg laying. At the time when laying capacity approached a maximum, a decrease was observed (P<0.05 in haematocrit, erythrocytes, and haemoglobin values, whereas monocytes, eosinophils, the heterophil/lymphocyte ratio, phosphorus, and calcium exhibited an increase (P<0.05. At the end of the laying period, an increase (P<0.05 was recorded in the count of leukocytes, heterophils, lymphocytes and basophils, the heterophil to lymphocyte ratio, and the concentrations of aspartate aminotransferase, cholesterol, phosphorus, and calcium, whereas lower values (P<0.05 were recorded for haematocrit and plasma total protein in comparison with the values of the indicators at the beginning of the laying period. The results provide new information about dynamic changes in selected haematological and biochemical parameters in clinically healthy common pheasant hens during the laying period.

    The peptide hormone ghrelin is suggested to be involved in food intake regulation in young growing chicken. Whether ghrelin is involved in the regulation of energetic balance associated with laying performance in adult laying hens was studied by use of 4 chicken lines that differ in laying performance and phylogeny (4 lines; 16 hens per line). As housing conditions are also known to affect energy demand, half of the hens per line were housed in single cages and the other half of hens were maintained in a floor housing system. Plasma samples were collected at 17 to 19, 33 to 35, 49 to 51, and 72 wk of age and analyzed with a chicken ghrelin ELISA Kit. From caged hens, individual food consumption and laying performance additionally was recorded. Due to its function in growth and its relationship with ghrelin, also GH plasma concentrations were analyzed. Ghrelin concentrations did not differ between the 4 lines at any of the test periods (all P > 0.05). Ghrelin was negatively related to food consumption only in the growing period of the high-performing lines (both P ghrelin concentrations compared with caged hens (P ghrelin is not involved in regulating energy intake related to laying performance but rather seems to be related to body growth and housing condition before start of lay, the latter possibly due to differences in hens' behavioral activity.

    α-Hexachlorocyclohexane (α-HCH) is a chiral organochlorine pesticide that is often ubiquitously detected in various environmental matrices and may be absorbed by the human body via food consumption, with serious detriments to human health. In this study, enantioselective degradation kinetics and residues of α-HCH in laying hens were investigated after a single dose of exposure to the pesticide, whereas enantioselectivity and residues of α-HCH in eggs, droppings, and various tissues were investigated after long-term exposure. Meanwhile, montmorillonite (MMT), a feed additive with high capacity of adsorption, was investigated for its ability to remove α-HCH from laying hens. Most non-brain tissues enantioselectively accumulated (-)-α-HCH, while (+)-α-HCH was preferentially accumulated in the brain. The enantiomer fractions (EFs) in most tissues gradually decreased, implying continuous depletion of (+)-α-HCH in laying hens. After 30 days of exposure and 31 days of elimination, the concentration of α-HCH in eggs and tissues of laying hens with MMT-containing feed was lower than that with MMT-free feed, indicating the removal effects of MMT for α-HCH in laying hens. The findings presented herein suggest that modified MMT may potentially be useful in reducing the enrichment of α-HCH in laying hens and eggs, thus lowering the risk of human intake of α-HCH.

  9. Growing Fixed With Age: Lay Theories of Malleability Are Target Age-Specific.

    Neel, Rebecca; Lassetter, Bethany

    2015-11-01

    Beliefs about whether people can change ("lay theories" of malleability) are known to have wide-ranging effects on social motivation, cognition, and judgment. Yet rather than holding an overarching belief that people can or cannot change, perceivers may hold independent beliefs about whether different people are malleable-that is, lay theories may be target-specific. Seven studies demonstrate that lay theories are target-specific with respect to age: Perceivers hold distinct, uncorrelated lay theories of people at different ages, and younger targets are considered to be more malleable than older targets. Both forms of target-specificity are consequential, as target age-specific lay theories predict policy support for learning-based senior services and the rehabilitation of old and young drug users. The implications of target age-specific lay theories for a number of psychological processes, the social psychology of aging, and theoretical frameworks of malleability beliefs are discussed. © 2015 by the Society for Personality and Social Psychology, Inc.

    Communal egg-laying is widespread among animals, occurring in insects, mollusks, fish, amphibians, reptiles, and birds, just to name a few. While some benefits of communal egg-laying may be pervasive (e.g., it saves time and energy and may ensure the survival of mothers and their offspring), the remarkable diversity in the life histories of the animals that exhibit this behavior presents a great challenge to discovering any general explanation. Reptiles and amphibians offer ideal systems for investigating communal egg-laying because they generally lack parental care--a simplification that brings nest site choice behavior into sharp focus. We exhaustively reviewed the published literature for data on communal egg-laying in reptiles and amphibians. Our analysis demonstrates that the behavior is much more common than previously recognized (occurring in 481 spp.), especially among lizards (N = 255 spp.), where the behavior has evolved multiple times. Our conceptual review strongly suggests that different forces may be driving the evolution and maintenance of communal egg-laying in different taxa. Using a game theory approach, we demonstrate how a stable equilibrium may occur between solitary and communal layers, thus allowing both strategies to co-exist in some populations, and we discuss factors that may influence these proportions. We conclude by outlining future research directions for determining the proximate and ultimate causes of communal egg-laying.

  11. Understanding Lay Assessments of Alcohol Use Disorder: Need for Treatment and Associated Stigma.

    Three-quarters of people with an alcohol use disorder in the USA never receive treatment. Our understandings of who receives care are informed by sociological perspectives, theories and models, each of which discuss the role of lay people's understanding of illness. However, comparatively little work has been done to unpack the cognitive processes underlying lay assessment. In the context of the Framework Integrating Normative Influences on Stigma (FINIS), we aim to understand key factors guiding lay people's stigmatizing attitudes, perceptions and assessments of alcohol use disorder behaviors. Lay people read a vignette depicting a male or female adult with a diagnosable alcohol use disorder, along with either a causal life-event explanation for the alcohol use disorder behaviors or no explanation. They then made judgments of the need for treatment, psychological abnormality and the stigma they felt toward the person depicted. Causal life-event explanations decreased lay judgments of the need for treatment, psychological abnormality and stigma. The results suggest that the availability of a causal life-event explanation may have a complex effect on lay judgments, decreasing the likelihood of recommending treatment for alcohol use disorders, yet simultaneously reducing stigmatizing perceptions (and presumably social distance). © The Author 2015.

    To evaluate and compare the impact of altered smile characteristics on the perception of smile esthetics between Moroccan dentists and lay people. Thirty-four digital smile photographs displaying alterations in crown length and width, lateral incisor gingival margin position, gingival exposition, midline diastema, and upper midline deviation were presented to a sample of 30 dentists and 30 lay people. The ratings were assessed with a visual analog scale. Compared to that of lay people, Moroccan dentists' evaluation of the gingival smile was more critical when the decrease in central incisor crown length was 2.5 mm ( p  lay people similarly evaluated irregularities in the incisor gingival margin position. Increases in the midline diastema were judged critically by both Moroccan dentists and lay people. In this sample, Moroccan dentists evaluate smile esthetic alterations more critically than Moroccan lay people. This difference in perception of smile discrepancies must be taken into account during the finishing phases of orthodontic treatment and restoration of the anterior teeth in Moroccan patients.

    To analyze gender differences in levels of psychological distress, financial strain, lay off experiences and job search activity among unemployed and re-employed individuals who were laid-off due to the collapse of the financial sector in Iceland in 2008. The study is based on questionnaires distributed to 759 former financial sector employees; 426 responses were received giving a 62.6% response rate. The groups of unemployed and re-employed woman and men are compared using separate multivariate binary models to control for mediating factors. The analysis reveals gender differences in demographic factors and jobs held prior to lay-off. More women than men were psychologically or finically distressed and claimed being shocked by the lay-off. A higher proportion of men than women were re-employed at the time of this study. The main difference between those re-employed and unemployed was lower financial strain among those re-employed for both men and women in this sample. The study does not support the traditional view of men having more difficulties in the lay-off process than women. This calls for a rethinking regarding gender in lay-off and unemployment. A gender-based analysis is needed when considering the ramifications of losing a job and job search activity in the lay-off process.

    Only an estimated 54% of people living with HIV are aware of their status. Despite progress scaling up HIV testing services (HTS), a testing gap remains. Delivery of HTS by lay providers may help close this testing gap, while also increasing uptake and acceptability of HIV testing among key populations and other priority groups. 50 National HIV testing policies were collated from WHO country intelligence databases, contacts and testing program websites. Data regarding lay provider use for HTS was extracted and collated. Our search had no geographical or language restrictions. This data was then compared with reported data from the Global AIDS Response Progress Reporting (GARPR) from July 2015. Forty-two percent of countries permit lay providers to perform HIV testing and 56% permit lay providers to administer pre-and post-test counseling. Comparative analysis with GARPR found that less than half (46%) of reported data from countries were consistent with their corresponding national HIV testing policy. Given the low uptake of lay provider use globally and their proven use in increasing HIV testing, countries should consider revising policies to support lay provider testing using rapid diagnostic tests.

    To evaluate and compare the perceptions of Saudi dentists and lay people to altered smile features. Thirty-six digital smile photographs with altered features were used. Altered features included the following: crown length, width, gingival level of the lateral incisors, gingival display, midline diastema, and upper midline shift. The photographs were presented to a sample of 30 dentists and 30 lay people with equal gender distribution. Each participant rated each picture with a visual analogue scale, which ranged from 0 (very unattractive) to 100 (very attractive). Dentists were more critical than lay people when evaluating symmetrical crown length discrepancies. Compared to lay people, Saudi dentists gave lower ratings to a crown length discrepancy of >2 mm (P 1 mm (P lay people towards alterations in the gingival level of the lateral incisors or towards a space between the central incisors. No significant sex difference was seen across the groups. In this sample, Saudi dentists gave significantly lower attractiveness scores to crown length and crown width discrepancies, midline deviations, and changes in gingiva to lip distance compared to Saudi lay people.

    To conduct a qualitative systematic review on the use of lay counsellors in South Africa to provide lessons on optimizing their use for psychological and behavioural change counselling for chronic long-term care in scare-resource contexts. A qualitative systematic review of the literature on lay counsellor services in South Africa. Twenty-nine studies met the inclusion criteria. Five randomized control trials and two cohort studies reported that lay counsellors can provide behaviour change counselling with good outcomes. One multi-centre cohort study provided promising evidence of improved anti-retroviral treatment adherence and one non-randomized controlled study provided promising results for counselling for depression. Six studies found low fidelity of lay counsellor-delivered interventions in routine care. Reasons for low fidelity include poor role definition, inconsistent remuneration, lack of standardized training, and poor supervision and logistical support. Within resource-constrained settings, adjunct behaviour change and psychological services provided by lay counsellors can be harnessed to promote chronic care at primary health care level. Optimizing lay counsellor services requires interventions at an organizational level that provide a clear role definition and scope of practice; in-service training and formal supervision; and sensitization of health managers to the importance and logistical requirements of counselling.

    The egg is the most complete natural food; it has all the necessary nutrients such as vitamins, aminoacids and essential minerals to maintain a life. However, although, has several proteins that promote allergies in considerable part of the world population. To determine allergenic food proteins, one of the most used tests is the immunoassays such as ELISA (enzyme linked immunosorbent assay), where the antibody recognizes the antigen and this connection is showed by an enzymatic system, in other words, optical density. The aim of this study was to determine the polyclonal antibody efficiency, produced in laboratory, to identify the presence the ovo mucoid antigen in treated eggs by gamma irradiation for its inactivation. To evaluate the treatments, polyclonal antibody was produced in four New Zealand female rabbits, at 45 days old, immunized with bio conjugated ovo mucoid. Was used Freund Complete Adjuvant at first immunization and PBS Buffer at four subsequently immunizations every fifteen days, plus a booster 48 hours before the blood retreated. The blood serum was tittered by PTA ELISA (Plate trapped antigen). All procedures were approved by Institute of Animal Science and Pastures (IZ)'s Committee of Ethical and Animal Experimentation and preceded according to European Norms for ethical and animal welfare. It was used, in nature, commercial laying eggs, from the Genetic Department of Agricultural University Luiz de Queiroz ESALQ/USP. So the samples were submitted to the gamma radiation coming from a source of 60 Co, type Multipurpose at the Energetically Researches and Nuclear Institute (IPEN), under a dose rate of 19.4 and 31.8Gy/hour, in the doses: 0 (control); 10KGy; 20KGy and 30KGy, in all rates. By the ELISA s test we can find the egg allergen ovo mucoid and the radiation treatment do not showed considerable changes. So we can concluded that the antibody produced is capable of identify the ovo mucoid allergenic protein and the gamma irradiation in such

    In this study, the range use and behaviour of laying hens in commercial free-range flocks was explored. Six flocks were each visited on four separate days and data collected from their outdoor area (divided into zones based on distance from shed and available resources). These were: apron (0-10 m from shed normally without cover or other enrichments); enriched belt (10-50 m from shed where resources such as manmade cover, saplings and dust baths were provided); and outer range (beyond 50 m from shed with no cover and mainly grass pasture). Data collection consisted of counting the number of hens in each zone and recording behaviour, feather condition and nearest neighbour distance (NND) of 20 birds per zone on each visit day. In addition, we used techniques derived from ecological surveys to establish four transects perpendicular to the shed, running through the apron, enriched belt and outer range. Number of hens in each 10 m × 10 m quadrat was recorded four times per day as was the temperature and relative humidity of the outer range. On average, 12.5% of hens were found outside. Of these, 5.4% were found in the apron; 4.3% in the enriched zone; and 2.8% were in the outer range. This pattern was supported by data from quadrats, where the density of hens sharply dropped with increasing distance from shed. Consequently, NND was greatest in the outer range, least in the apron and intermediate in the enriched belt. Hens sampled in outer range and enriched belts had better feather condition than those from the apron. Standing, ground pecking, walking and foraging were the most commonly recorded activities with standing and pecking most likely to occur in the apron, and walking and foraging more common in the outer range. Use of the outer range declined with lower temperatures and increasing relative humidity, though use of apron and enriched belt was not affected by variation in these measures. These data support previous findings that outer range areas tend to be

    The development of an academic surgical career can be an overwhelming prospect, and one that is not intuitive. Establishing a structured plan and support structure is critical to success. Starting a successful academic surgical career begins with defining one's academic goals within several broad categories: personal goals, academic goals, research goals, educational goals, and financial goals. Learning the art of self-promotion is the means by which many of these goals are achieved. It is important to realize that achieving these goals requires a delicate personal balance between work and home life, and the key ways in which to achieve success require establishment of well thought-out goals, a reliable support structure, realistic and clear expectations, and frequent re-evaluation.

    In medicine, the challenges faced by female faculty members who are attempting to achieve academic advancement have been well described. Various strategies have been proposed to increase academic productivity to aid the promotion of women in medicine. We propose an innovative collaboration strategy that encourages completion of an academic writing project. This strategy acknowledges the challenges inherent in achieving work-life balance and utilizes a collaborative work style with a group of peer physicians. The model is designed to encourage the completion and collation of independently prepared sections of an academic paper within a setting that emphasizes social networking and collaboration. This approach has many similarities to the construction of a quilt during a "quilting bee."

    Chinese Americans have low colorectal cancer (CRC) screening rates. Evidence-based interventions to increase CRC screening in this population are lacking. This study aims to compare the efficacy of two interventions in increasing CRC screening among Chinese Americans. Cluster randomized comparative trial. From 2010 to 2014, a community-academic team conducted this study in San Francisco, CA with Chinese Americans aged 50-75 years who spoke English, Cantonese, or Mandarin. Lay health worker (LHW) intervention plus in-language brochure (LHW+Print) versus brochure (Print). LHWs in the LHW+Print arm were trained to teach participants about CRC in two small group sessions and two telephone calls. Change in self-reports of ever having had CRC screening and being up to date for CRC screening from baseline to 6 months post-intervention. Statistical analysis was performed from 2014 to 2015. This study recruited 58 LHWs, who in turn recruited 725 participants. The average age of the participants was 62.2 years, with 81.1% women and 99.4% foreign born. Knowledge increase was significant (pPrint group and six in the Print group. Both groups had increases in having ever been screened for CRC (LHW+Print, 73.9%-88.3%, pPrint, 72.3%-79.5%, p=0.0003) and being up to date for CRC screening (LHW+Print, 60.0%-78.1%, pPrint, 58.1%-64.1%, p=0.0003). In multivariable analyses, the intervention OR for LHW+Print versus Print was 1.94 (95% CI=1.34, 2.79) for ever screening and 2.02 (95% CI=1.40, 2.90) for being up to date. Both in-language print materials and LHW outreach plus print materials increased CRC screening among Chinese Americans. The combination of LHW+Print was more effective than Print alone. These findings can guide clinicians and policymakers in choosing appropriate interventions to increase CRC screening among Chinese American immigrants.

    Academic incivility can increase student stress, jeopardize learning, damage relationships, and negatively impact the academic environment. This 3-year longitudinal study measured a cohort of prelicensure nursing students' progressive perceptions of stress, coping, student-student and faculty-student relationships, and levels of academic civility. While civility scores remained mild to moderately high overall, there was a slightly declining trend over the 3-year period. Perceived stressors and coping strategies and ways to improve academic civility are identified and discussed.

    Academic medical centers have responded to health care reform initiatives by launching a series of strategic plans designed to maintain patient flow and reduce hospital expenditures. Thought is also being given to processes by which the faculty can individually and collectively adjust to these changes and maintain morale at a time when reductions in the labor force and pay cuts are virtually certain. Physicians are concerned because managed care threatens their autonomy and jeopardizes the traditional ways in which they have carried out their multiple missions. Some doctors believe that it will become increasingly difficult to obtain genuine satisfaction from their job. The strategies that academic medical centers have begun to use to address the numerous challenges posed by a system of health care based on managed competition are reviewed. Potential mechanisms by which academic departments can continue to find fulfillment in an environment that threatens their traditional missions and values are discussed. A study of the social and historical origins of medicine in the United States reveals that the introduction of corporate medicine in the United States was destined to happen. Strategies implemented by academic medical centers in response to managed care include building an integrated delivery network, the acquisition of primary care practices, increasing cost-effectiveness, and creating physician-hospital organizations. Emphasis must be placed on integrating traditional core values (excellence, leadership, and innovation) with newer values such as patient focus, accountability, and diversity. A shift from rugged individualism to entrepreneurial teamwork is crucial. These reforms, although frightening at the onset, can serve to reaffirm our commitment to academic medicine and preserve our mission. The evolving managed care environment offers unique opportunities for academic medical centers to shape and positively impact health care delivery in the twenty

  12. Outsourcing of Academic Clinical Laboratories

    American hospitals are increasingly turning to service outsourcing to reduce costs, including laboratory services. Studies of this practice have largely focused on nonacademic medical centers. In contrast, academic medical centers have unique practice environments and unique mission considerations. We sought to elucidate and analyze clinical laboratory outsourcing experiences in US academic medical centers. Seventeen chairs of pathology with relevant experience were willing to participate in in-depth interviews about their experiences. Anticipated financial benefits from joint venture arrangements often eroded after the initial years of the agreement, due to increased test pricing, management fees, duplication of services in support of inpatients, and lack of incentive for utilization control on the part of the for-profit partner. Outsourcing can preclude development of lucrative outreach programs; such programs were successfully launched in several cases after joint ventures were either avoided or terminated. Common complaints included poor test turnaround time and problems with test quality (especially in molecular pathology, microbiology, and flow cytometry), leading to clinician dissatisfaction. Joint ventures adversely affected retention of academically oriented clinical pathology faculty, with adverse effects on research and education, which further exacerbated clinician dissatisfaction due to lack of available consultative expertise. Resident education in pathology and in other disciplines (especially infectious disease) suffered both from lack of on-site laboratory capabilities and from lack of teaching faculty. Most joint ventures were initiated with little or no input from pathology leadership, and input from pathology leadership was seen to have been critical in those cases where such arrangements were declined or terminated.

  14. Evaluation of Hand Lay-Up and Resin Transfer Molding in Composite Wind Turbine Blade Manufacturing

    The majority of the wind turbine blade industry currently uses low cost hand lay-up manufacturing techniques to process composite blades. While there are benefits to the hand lay-up process, drawbacks inherent to this process along with advantages of other techniques suggest that better manufacturing alternatives may be available. Resin Transfer Molding (RTM) was identified as a processing alternative and shows promise in addressing the shortcomings of hand lay-up. This report details a comparison of the RTM process to hand lay-up of composite wind turbine blade structures. Several lay-up schedules and critical turbine blade structures were chosen for comparison of their properties resulting from RTM and hand lay-up processing. The geometries investigated were flat plate, thin and thick flanged T-stiffener, I-beam, and root connection joint. It was found that the manufacturing process played an important role in laminate thickness, fiber volume, and weight for the geometries investigated. RTM was found to reduce thickness and weight and increase fiber volumes for all substructures. RTM resulted in tighter material transition radii and eliminated the need for most secondary bonding operations. These results would significantly reduce the weight of wind turbine blades. Hand lay-up was consistently slower in fabrication times for the structures investigated. A comparison of mechanical properties showed no significant differences after employing fiber volume normalization techniques to account for geometry differences resulting from varying fiber volumes. The current root specimen design does not show significant mechanical property differences according to process and exceeds all static and fatigue requirements.

    Full Text Available Abstract Background The human resource shortage in Zambia is placing a heavy burden on the few health care workers available at health facilities. The Zambia Prevention, Care and Treatment Partnership began training and placing community volunteers as lay counsellors in order to complement the efforts of the health care workers in providing HIV counselling and testing services. These volunteers are trained using the standard national counselling and testing curriculum. This study was conducted to review the effectiveness of lay counsellors in addressing staff shortages and the provision of HIV counselling and testing services. Methods Quantitative and qualitative data were collected by means of semistructured interviews from all active lay counsellors in each of the facilities and a facility manager or counselling supervisor overseeing counseling and testing services and clients. At each of the 10 selected facilities, all counselling and testing record books for the month of May 2007 were examined and any recordkeeping errors were tallied by cadre. Qualitative data were collected through focus group discussions with health care workers at each facility. Results Lay counsellors provide counselling and testing services of quality and relieve the workload of overstretched health care workers. Facility managers recognize and appreciate the services provided by lay counsellors. Lay counsellors provide up to 70% of counselling and testing services at health facilities. The data review revealed lower error rates for lay counsellors, compared to health care workers, in completing the counselling and testing registers. Conclusion Community volunteers, with approved training and ongoing supervision, can play a major role at health facilities to provide counselling and testing services of quality, and relieve the burden on already overstretched health care workers.

    Survival rates after out-of-hospital cardiac arrest (OHCA) vary considerably among regions. The chance of survival is increased significantly by lay rescuer cardiopulmonary resuscitation (CPR) before Emergency Medical Services (EMS) arrival. It is well known that for bystanders, reasons for not providing CPR when witnessing an OHCA incident may be fear and the feeling of being exposed to risk. The aim of this study was to gain a better understanding of why barriers to providing CPR are overcome. Using a semi-structured interview guide, 10 lay rescuers were interviewed after participating in eight OHCA incidents. Qualitative content analysis was used. The lay rescuers were questioned about their CPR-knowledge, expectations, and reactions to the EMS and from others involved in the OHCA incident. They also were questioned about attitudes towards providing CPR in an OHCA incident in different contexts. The lay rescuers reported that they were prepared to provide CPR to anybody, anywhere. Comprehending the severity in the OHCA incident, both trained and untrained lay rescuers provided CPR. They considered CPR provision to be the expected behavior of any community citizen and the EMS to act professionally and urgently. However, when asked to imagine an OHCA in an unclear setting, they revealed hesitation about providing CPR because of risk to their own safety. Mutual trust between community citizens and towards social institutions may be reasons for overcoming barriers in providing CPR by lay rescuers. A normative obligation to act, regardless of CPR training and, importantly, without facing any adverse legal reactions, also seems to be an important factor behind CPR provision.

    While increasing evidence suggests that observers discount high-severity chronic pain, factors that occasion such discounting are poorly understood, particularly regarding health provider vs lay perspectives. This study examined the effects of supporting medical evidence and comorbid psychological distress (pain behavior) on medical student and lay clinical judgments of increasingly severe patient pain reports. In a 2 × 2 × 2 × (7) mixed between- and within-subject design, participants (medical students vs lay) made clinical judgments after reading vignettes describing a hypothetical patient that varied in levels of medical evidence and pain behavior (low vs high) and pain severity (4/10-10/10). Fourth-year medical students (N = 115) and lay persons in the community (N = 300) participated in this research. While both medical student and lay judgments plateaued at high levels of pain severity, judgments regarding cause (medical vs psychological), treatment (opioid prescription), and disability showed growing divergence as levels of reported pain severity increased. Divergence relative to medical and psychological causes of pain was found irrespective of the level of supporting medical evidence; divergence relative to opioid treatment and support for a disability claim was found when supporting medical evidence was low. The results indicate differing expectations of chronic pain treatment for health care providers relative to the lay public that could impact clinical care, especially at high pain severity levels, where lay expectations diverge significantly from those of health professionals. © 2015 American Academy of Pain Medicine.

  18. Vaunting the independent amateur: Scientific American and the representation of lay scientists.

    Science.gov (United States)

    Johnston, Sean F

    2018-04-01

    This paper traces how media representations encouraged enthusiasts, youth and skilled volunteers to participate actively in science and technology during the twentieth century. It assesses how distinctive discourses about scientific amateurs positioned them with respect to professionals in shifting political and cultural environments. In particular, the account assesses the seminal role of a periodical, Scientific American magazine, in shaping and championing an enduring vision of autonomous scientific enthusiasms. Between the 1920s and 1970s, editors Albert G. Ingalls and Clair L. Stong shepherded generations of adult 'amateur scientists'. Their columns and books popularized a vision of independent non-professional research that celebrated the frugal ingenuity and skills of inveterate tinkerers. Some of these attributes have found more recent expression in present-day 'maker culture'. The topic consequently is relevant to the historiography of scientific practice, science popularization and science education. Its focus on independent non-professionals highlights political dimensions of agency and autonomy that have often been implicit for such historical (and contemporary) actors. The paper argues that the Scientific American template of adult scientific amateurism contrasted with other representations: those promoted by earlier periodicals and by a science education organization, Science Service, and by the national demands for recruiting scientific labour during and after the Second World War. The evidence indicates that advocates of the alternative models had distinctive goals and adapted their narrative tactics to reach their intended audiences, which typically were conceived as young persons requiring instruction or mentoring. By contrast, the monthly Scientific American columns established a long-lived and stable image of the independent lay scientist.

    Full Text Available The aim of this study was to evaluate PM10 concentration in three different laying hens houses (traditional battery cages with aerated open manure storage, aviary system and vertical tiered cages with manure belts with forced air drying and to evaluate particulate matter emission into atmosphere during one year of observation. Internal and external temperature and relative humidity, ventilation rate, PM10 concentration have been continuously monitored in order to evaluate particulate matter concentration changes during the day and the season and to define PM10 emission factors. PM10 concentration was corrected by gravimetric technique to lower measurements error. In the aviary system house, TSP and fine particulate matter (particles smaller than 2.5 micron concentration was measured. Average yearly PM10 concentration was remarkably higher in the aviary system house with 0.215 mg m-3 vs 108 mg m-3 for the ventilated belt house and vs 0.094 mg m-3 for the traditional battery cages house. In the Aviary system housing, TSP concentration was 0.444 mg m-3 and PM2.5 was 0.032 mg m-3, highlighting the existence of a severe working environment for men and animals. Recorded values for PM10 emission were 0.433 mg h-1 hen-1 for battery cages housing type, 0.081 mg h-1 hen-1 for ventilated belt cages house, values lower than those available in literature, while the aviary system housing type showed the highest PM10 emission (1.230 mg h-1 hen-1 with appreciable peaks during the morning, together with the increased animal activity and daily farmer operations, as feed administration, cleaning and droppings removal.

  20. Whistleblowing in academic medicine

    2004-01-01

    The authors present and discuss cases of academic medicine failing to address unethical behaviour in academic science and, thereby, illustrate the scope and seriousness of the problem. The Olivieri/Apotex affair is just another instance of academic medicine's dereliction in a case of scientific fraud and misconduct. Instead of vigorously supporting their faculty member in her efforts to honestly communicate her findings and to protect patients from the risks associated with the use of the study drug, the University of Toronto collaborated with the Apotex company's "stalling tactics," closed down Dr Olivieri's laboratory, harassed her, and ultimately dismissed her. The authors argue that the incentives for addressing problematic behaviour have to be revised in order to effect a change in the current pattern of response that occurs in academic medicine. An externally imposed realignment of incentives could convert the perception of the whistleblower, from their present caste as the enemy within, into a new position, as valued friend of the institution. The authors explain how such a correction could encourage appropriate reactions to scientific misconduct from academic medicine. PMID:14872069
