Résumé :

The purposes of the study were to develop a theoretical model to explain the relationships between immigration transition and midlife women’s physical activity and test the relationships among the major variables of the model. A theoretical model, which was developed based on transitions theory and the midlife women’s attitudes toward physical activity theory, consists of 4 major variables, including length of stay in the United States, country of birth, level of acculturation, and midlife women’s physical activity. To test the theoretical model, a secondary analysis with data from 127 Hispanic women and 123 non-Hispanic (NH) Asian women in a national Internet study was used. Among the major variables of the model, length of stay in the United States was negatively associated with physical activity in Hispanic women. Level of acculturation in NH Asian women was positively correlated with women’s physical activity. Country of birth and level of acculturation were significant factors that influenced physical activity in both Hispanic and NH Asian women. The findings support the theoretical model that was developed to examine relationships between immigration transition and physical activity; it shows that immigration transition can play an essential role in influencing health behaviors of immigrant populations in the United States. The NH theoretical model can be widely used in nursing practice and research that focus on immigrant women and their health behaviors. Health care providers need to consider the influences of immigration transition to promote immigrant women’s physical activity.

Résumé :

Background: Despite the frequency and negative impact of low physical activity among patients with chronic obstructive pulmonary disease (COPD), little is known about how it persists and remits over time or the factors predicting new states of low physical activity. The aim of the study was to determine the probability of a transition between states of low and nonlow physical activity in a cohort of patients with stable COPD followed for 2 years. We also investigated different potentially modifiable factors to determine whether they can predict new states of low physical activity. Methods: We prospectively included 137 patients with stable COPD (mean age 66.9 ± 8.3 years). Physical activity was measured at baseline and at 1 and 2 years of follow up. Low physical activity was defined according to energy expenditure by cut-off points from the Fried frailty model. The likelihood of annual transition towards new states and recovery was calculated. We evaluated demographic, frailty, nonrespiratory, and respiratory variables as potential predictors, using generalized estimating equations. Results: At baseline, 37 patients (27%) presented with low physical activity. During the study period, a total of 179 annual transitions were identified with nonlow physical activity at the beginning of the year; 17.5% transitioned to low physical activity. In contrast, 34.3% of the 67 transitions that started with low physical activity recovered. Predictors of transition to new states of low physical activity were dyspnea ⩾2 (odds ratio = 3.21; 95% confidence interval: 1.20–8.61) and poor performance on the five sit-to-stand test (odds ratio = 4.75; 95% confidence interval: 1.30–17.47). Conclusions: The change between levels of low and nonlow physical activity is dynamic, especially for recovery. Annual transitions toward new states of low physical activity are likely among patients with dyspnea or poor performance on the five sit-to-stand test.

Résumé :

PurposeIn this study, the authors offer a practice theory framing of school physical activity transition with conceptual and managerial contributions to whole school approaches (WSAs).Design/methodology/approachBased on a literature overview of the limitations of WSA, ecological and systems theorisation and a practice theory framing of physical activity, the authors introduce a model that identifies signs of practice transition and conceptualises the relationship between signs and practice reconfigurations. To exemplify insights from the model, the authors provide illustrations from three cases from the national Estonian “Schools in Motion” programme.FindingsThe signs of practitioner effort, resistance and habituation indicate how practice ecosystem transition is unfolding across a spectrum from practice differentiation to routinisation. Several signs of transition, like resistance, indicate that reconfigured practices are becoming established. Also, there are signs of habituation that seemingly undermine the value of the programme but should instead be celebrated as valuable evidence for the normalisation of new practices.Practical implicationsThe article provides a model for WSA programme managers to recognise signs of transition and plan appropriate managerial activities.Originality/valueThe practice theory framing of school physical activity transition advances from extant theorizations of WSAs that have failed to account for the dynamic ways that socio-cultural change in complex school settings can unfold. A model, based on a practice ontology and concepts from theories of practice, is proposed. This recognises signs of transition and can help with the dynamic and reflexive management of transition that retains the purpose of systemic whole school change.

Résumé :

AbstractObjective:Socio-economic development influences many factors that affect health, especially diet and nutrition. This investigation proposes that a system of transitions occur as societies develop, with socio-economic, physical activity, dietary, nutrition and body weight transitions operating in relationship with each other. This model of transitions was examined empirically using South Korea as an example of a nation that has undergone considerable changes.Design:Data were drawn from published government reports: the Korean National Nutrition Survey and annual reports at the national level for the years between 1969 and 1993. The socio-economic transition was assessed by gross national product. The physical activity transition was assessed using annual proportions of the population involved in primary, secondary and tertiary industries, as well as the number of cars and driver's licences. The dietary transition was measured by plant and animal food consumption. The nutrition transition was assessed by percentages of energy from carbohydrate, protein and fat. The body weight transition was measured by body mass index calculated from the average height and weight of adolescents.Results:Results revealed that the transitions were highly correlated as expected, with the socio-economic transition exhibiting major changes. South Koreans tended to decrease their physical activity and plant food consumption, and to increase animal food consumption, percentage of energy from dietary fat and body weight, in relationship to the socio-economic transition.Conclusion:Examining a system of transitions on a national level in one country that has undergone rapid economic development may provide a strategy for examining how such transitions operate in other nations.

Résumé :

Gender Specific Developmental Dynamics between Physical Education Task Values and Physical Activity during Junior High School This study investigated the gender specific developmental dynamics of students' physical education task values and physical activity across junior high school. A total of 812 (430 boys, 382 girls, Mage = 12.31, age range = 11 to 13) students' were examined three times during their transition from Grade 7 to Grade 9. Furthermore, their physical activity at Grade 6 was measured. Multivariate simplex-model analyses found degreasing pattern of student' physical education task motivation and physical activity. The decrease of students' task values leveled off at Grades 8 and 9, whereas students' physical activity for both genders continued to decrease across Grades 7 to 9. In addition, students' physical education task values predicted their subsequent physical activity when previous levels of values and activity as well as physical activity at Grade 6 were controlled. Although boys' valued physical education more and they were more physically active, there were no gender differences in the pattern of development of physical education task values and physical activity. These findings indicate that the development of students' physical activity might be affected by fostering their values toward physical education.

Résumé :

Background. The transtheoretical model (TTM) views individual behavioral change as a nonlinear, dynamic process, which is consistent with the complex nature of physical activity (PA) in children and adolescents. However, within this theoretical framework, the elements that facilitate the behavioral change in PA in children and adolescents need to be further explored. Objective. A systematic review of research related to TTM-based exploration of the elements of behavioral change in PA in children and adolescents, an analysis of the strengths and weaknesses in practice, and an outlook for future research. Materials and Methods. After computer searches of the CNKI, Wan-Fang, VIP, WOS, PubMed, and EBSCO databases, two researchers independently screened articles, extracted information, and evaluated the quality of the articles. Results. A total of 25 articles (26 studies) of medium- to high-quality were included in the systematic review. The meta-analysis included 30,106 children and adolescents aged 11.24 to 17.7 years. The counter-conditioning and self-liberation of the process of change, self-efficacy and decisional balance are key elements that facilitate the transition of the PA stage in children and adolescents. Extramodel psychological variables such as exercise motivation play a moderate to large role in the PA stage transition. In addition, VPA is an important discriminator of PA stage transition in children and adolescents. Conclusion. It is recommended that interventions be designed according to the key elements of behavioral change in order to better facilitate the PA stage transition of children and adolescents.

Résumé :

Immigrants to Canada are less likely to be physically active compared with non-immigrants, and the interrelations between personal and environmental factors that influence physical activity for immigrants are largely unexplored. The goal of this qualitative descriptive study was to understand how the experience of being new to Canada impacts opportunities and participation in physical activity. Two focus group interviews with immigrants to Canada were conducted. The first group ( n=7) included multicultural health brokers. The second group ( n=14) included English as a second language students. Qualitative content analysis was used to determine three themes consistent with the research question: transition to Canadian life, commitments and priorities, and accessibility. Discussion was framed using a social ecological model. Implications for practice and policy are suggested including enhanced community engagement, and organizational modifications. Overall, the development and implementation of physical activity policies and practices for newcomers to Canada should be centered on newcomers’ perspectives and experiences.

Résumé :

Abstract Objective The objective of this study is to characterize the dynamic structure of primary care consultations by identifying typical activities and their inter-relationships to inform the design of automated approaches to clinical documentation using natural language processing and summarization methods. Materials and Methods This is an observational study in Australian general practice involving 31 consultations with 4 primary care physicians. Consultations were audio-recorded, and computer interactions were recorded using screen capture. Physical interactions in consultation rooms were noted by observers. Brief interviews were conducted after consultations. Conversational transcripts were analyzed to identify different activities and their speech content as well as verbal cues signaling activity transitions. An activity transition analysis was then undertaken to generate a network of activities and transitions. Results Observed activity classes followed those described in well-known primary care consultation models. Activities were often fragmented across consultations, did not flow necessarily in a defined order, and the flow between activities was nonlinear. Modeling activities as a network revealed that discussing a patient’s present complaint was the most central activity and was highly connected to medical history taking, physical examination, and assessment, forming a highly interrelated bundle. Family history, allergy, and investigation discussions were less connected suggesting less dependency on other activities. Clear verbal signs were often identifiable at transitions between activities. Discussion Primary care consultations do not appear to follow a classic linear model of defined information seeking activities; rather, they are fragmented, highly interdependent, and can be reactively triggered. Conclusion The nonlinearity of activities has significant implications for the design of automated information capture. Whereas dictation systems generate literal translation of speech into text, speech-based clinical summary systems will need to link disparate information fragments, merge their content, and abstract coherent information summaries.

Résumé :

Recent developments in sensor technologies enable physical activity recognition (PAR) as an essential tool for smart health monitoring and for fitness exercises. For efficient PAR, model representation and training are significant factors contributing to the ultimate success of recognition systems because model representation and accurate detection of body parts and physical activities cannot be distinguished if the system is not well trained. This paper provides a unified framework that explores multidimensional features with the help of a fusion of body part models and quadratic discriminant analysis which uses these features for markerless human pose estimation. Multilevel features are extracted as displacement parameters to work as spatiotemporal properties. These properties represent the respective positions of the body parts with respect to time. Finally, these features are processed by a maximum entropy Markov model as a recognition engine based on transition and emission probability values. Experimental results demonstrate that the proposed model produces more accurate results compared to the state-of-the-art methods for both body part detection and for physical activity recognition. The accuracy of the proposed method for body part detection is 90.91% on a University of Central Florida’s (UCF) sports action dataset and, for activity recognition on a UCF YouTube action dataset and an IM-DailyRGBEvents dataset, accuracy is 89.09% and 88.26% respectively.

Résumé :

Physical inactivity likely plays a role in the development of insulin resistance and obesity; however, direct evidence is minimal and mechanisms of action remain unknown. Studying metabolic outcomes that occur after transitioning from higher to lower levels of physical activity is the best tool to answer these questions. Previous studies have successfully used more extreme models of inactivity, including bed rest, or the cessation of exercise in highly trained endurance athletes, to provide novel findings. However, these models do not accurately reflect the type of inactivity experienced by a large majority of the population. Recent studies have used a more applicable model in which active (∼10,000 steps/day), healthy young controls are asked to transition to an inactive lifestyle (∼1,500 steps/day) for a 14-day period. The transition to inactivity resulted in reduced insulin sensitivity and increased central adiposity. This review will discuss the outcomes of these studies, their implications for the cause/effect relationship between central adiposity and insulin resistance, and provide rationale for why inactivity induces these factors. In addition, the experimental challenges of directly linking acute responses to inactivity to chronic disease will also be discussed.

Résumé :

Rapid advancement in the field of Artificial Intelligence, to be more specific in Machine Learning and Nanotechnology, strengthens hopes to better understand human mind. Ubiquitous Computing helped in the creation of intelligent environments pervaded by these visible and invisible devices, which are affecting and improving all aspects of human life. So, as a consequence, smart environments work on the behalf of humans for ease of comfort. The ultimate goal is to monitor humans without any awareness by them of computer interaction. The understanding of how humans will interact and make use of such systems is however largely unresolved and often not addressed collectively from both scientific and medical aspects in current research. A key to understanding such systems and their use is the observation that humans implicitly interact with their environment. The task of making this context information available to components in computer systems has become a prerequisite to move forward in human- computer interaction. Context awareness or more specifically how to create applications that are context aware is a central issue to Ubiquitous Computing research. Such research raises questions on context acquisition, context representation, distribution and abstraction, as well as programming paradigms, development support, and implications on human-computer interaction in general. The aim of this thesis is to develop part of a ubiquitous care system to monitor elderly basic daily life activities; stand, sit, walk, lay and transitional activities. This thesis investigates the use of a wearable sensor (tri-axial accelerometer) to develop and evaluate the activity classification scheme with reliable accuracy in the real-world situations. The recognition of these activities is challenging because activities with similar posture are hard to discriminate (e.g. stand and sit). Moreover, this high similarity among activities is not uniform throughout the whole dataset which raises the question of how much training data would be required. Furthermore, the activity classification schemes proposed in literature are typically subject-independent; however there is lack of evidence that such subject-independent schemes have been successfully validated with elderly in uncontrolled situations.

Résumé :

The present study tested (1) the validity of the transtheoretical model [TTM] and its prediction that stage-matched interventions are more effective than stage-mismatched interventions at promoting stage transition, and (2) the hypothesized theoretical mediators of regular physical activity and adjacent stage progression. Sedentary or insufficiently active adults (N = 190) recruited through corporate email newsletters were randomized to receive either a stage-matched, stage-mismatched, or standard care intervention. Stage-matched interventions were designed to alter hypothesized theoretical mediators of adjacent stage progression for regular moderate-intensity physical activity through print-based materials. This experimental study focused on two stage transitions, from contemplation to preparation and from preparation to action. Physical activity behavior, stage transition, and hypothesized theoretical mediators of physical activity participation and forward transition between adjacent stages were assessed at baseline and 8-week follow-up (83% retention rate). Based on results from a preliminary cross-sectional study (N = 1,172) that examined patterns of differences between adjacent stages (discontinuity patterns) on theoretical constructs hypothesized by the TTM to differ across stages, it was hypothesized that an increase in the perceived benefits and a decrease in the perceived costs of regular physical activity mediated progression from contemplation to preparation whereas an increase in self-efficacy and behavioral processes of change were hypothesized to mediate progression from preparation to action. Results revealed significant increase in physical activity behavior and stage progression across all conditions. Stage-matched, stage-mismatched, and standard care interventions produced equivalent results in terms of adjacent stage progression, physical activity participation, and proportion of individuals meeting CDC/ACSM guidelines at post-intervention follow-up. Behavioral processes of change were the only theoretical constructs to consistently predict progression to the next stage in the sequence for individuals in the preparation stage and increase in physical activity behavior for individuals in the contemplation and preparation stage. None of the theoretical constructs predicted adjacent stage progression for individuals in the contemplation stage. Preliminary evidence does not support the matching of interventions to stage in the context of regular physical activity and challenges the notion that stages of change, or at least a subset of them, are qualitatively distinct.

Résumé :

The purpose of this thesis was to explore socially constructed discursive barriers to physical activity for people with physical disabilities. This research was informed by a critical disability studies framework. Eight interviews were conducted, split between end-users and stakeholders. The end-user article discusses their perspectives with regard to their own PA participation, their use of PA resources, and their views of how disability is constructed. The stakeholder article deals with their views with regard to Canada’s progress in creating inclusive PA guidelines, the research process as it effects people with physical disabilities, and how disability is constructed. The results showed awareness among both groups of the social model of disability, but that the medical model is still firmly rooted. Work is needed to create inclusive promotional materials and disseminate them effectively. An effective advocacy and lobbying effort was suggested as one avenue towards a possible solution to this issue.

Résumé :

The purpose of this study was to investigate to what extent university students are regularly physically active, what motives and barriers they perceive towards exercise and the relationship between motivational profile, self-efficacy and exercise behaviors. A questionnaire including the instruments Physical Activity Stages of Change, BARSE, BREQ-2 and Exercise Adherence Questionnaire was distributed at a university in southern Sweden. The respondents (n = 251) were Men (n = 104) and Women (n = 147). For analysis and processing of the gathered data SPSS was used with One-Way ANOVA, Pearson's r and Regression Analysis. The study showed that 70 percent of the students were regularly physically active. The most common motives for exercise were to improve health and increase physical strength whilst the most frequent barriers were lack of motivation and lack of energy/fatigue. The results also revealed positive correlations between identified regulation, intrinsic regulation, barrier self-efficacy and physical activity.

Résumé :

Physical inactivity is one of the major public health problems of the 21st Century. In England it is reported that two thirds of adults ( > 16 yr) and one third of children ( < 16 yr) do not do sufficient physical activity to gain the health benefits that leading a physically active lifestyle has to offer. The benefits of physical activity and dangers of a sedentary lifestyle to health outcomes are well documented and numerous studies have investigated physical activity participation. Indeed, many interventions have been trialled to increase engagement in physical activity; however results are weak and generally do not correlate to sustained physical activity participation. Furthermore, much debate exists on how best to encourage both children and adults alike to engage in sufficient physical activity to maintain a healthy lifestyle. The purpose of this research was to address this important research gap and to assess the physical activity levels and other factors for promoting engagement in physical activity of school aged children in Devon aged 7-15 years in order to assess the feasibility of using social marketing within the school setting to increase sustained physical activity participation. A mixed methods approach was adopted to gather data and consisted of both quantitative and qualitative methods, in two phases. The initial phase was quantitative in nature and utilised a self-report survey based on the theory of planned behaviour (TPB) (Azjen, 1991) and social cognitive theory (SCT) (Bandura, 1977) to measure the participants’ physical activity levels; it also measured their beliefs and attitudes, subjective norms, perceived behavioural control and self-efficacy pertaining to physical activity participation. The second phase utilised qualitative methods adopting the socio-ecological model (McLeroy et al., 1988) to identify opportunities to promote participation in physical activity in recognising the multiple factors (individual, social environment, physical environment and policy) that influence an individual’s behaviour. This phase consisted of a series of interviews with the students, teachers and head-teachers to enable the researcher to gain in depth information into physical activity patterns and beliefs. During phase two, ethnographic research was also conducted across a number of schools in Devon to complement and enhance the data collected in the survey. The results revealed that of the 1124 participants (‘students’) surveyed, 48% were not sufficiently active to meet the government guidelines. Males were 30% more active than females. Physical activity decreased with age (e.g. 15 yr olds on average taking part in 3 hours less activity than 7 yr olds). Lifestyle/recreational activities were the most regularly participated activities (e.g. walking – 52%, running – 31%, football – 29%, outdoor play – 28%). Moreover, attitudes, subjective norms and perceptions of behavioural control affected physical activity participation both in and out of the school setting. Self-efficacy also played a role in physical activity participation. The results of the thesis show that interview and ethnographic data produced a rich source of evidence. Physical activity provision within schools played a major role in students’ physical activity. Overwhelmingly the qualitative data revealed that students want greater choice in the physical activities they participate in and suggest that the focus of PE lessons should be on having fun and enjoyment rather than skills and rules. Transition from primary to secondary school affected physical activity participation and therefore experiences in schools, may affect children’s general views on physical activity which it is suggested may impact on physical activity participation beyond the school gates and also in adulthood. This thesis provides substantial evidence to support the link between the school environment and participation in physical activity in children and adolescents. More specifically it highlights a need to incorporate a ‘whole school approach’ to physical activity participation. This research has demonstrated that there is an urgent need to combine theory based physical activity research in schools with that of social marketing. Physical activity researchers and social marketers should combine their knowledge to bring together social marketing campaigns within schools to enhance the health and wellbeing of the whole school environment for both staff and students. An innovative school based social marketing campaign should encourage physical activity both within and outside the school environment and lead to sustained levels of physical activity participation across the life stages.

Résumé :

In my thesis I explain patterns and developments of current participation in sport and physical activity among a group of men and women in the transition to early mid-life (38-43 years of age). I examine their perceptions of the activity and sense of sporting identity over their lives. There is limited research on mid-life experiences of sport and physical activity and more often this takes a social survey approach. The interpretive research on mid-life is still an emerging field, previous research has often focused on a single sport sub-culture, those who are heavily involved in sport, or women only. In depth, topical life history interviews and written timelines were completed with a group of sixteen individuals in this life stage, with varied experiences of sport and physical activity. The data was analysed using Brown and Gilligan's (1992, 1993) `voice centred relational method' of analysis, followed by 'constant comparison' (Glaser and Strauss, 1967) and coding (Strauss and Corbin, 1998). The major theme identified in this study was the complex construction of sport and participation, understood as it relates to the participants lives as a whole and its impact on their participation decision making. Sub-themes included; the different meaning and value of sport and self definition in relation to this, and changes in these across the life course (particularly the transition to midlife) and in relation to the ageing process and relationships. The research demonstrates the relationship between sport and the needs at this life stage, highlighting identity management, and values placed on the ethic of care and sport and physical activity as leisure. Conflicting feelings are experienced in relation to sport and physical activity due to constraints on and into participation. Further to this the thesis provides a grounded theory model of the construction of these activities in the transition to early midlife. The findings were interpreted with theoretical perspectives from: structuration (Giddens, 1979, 1984), dramaturgical (Goffman, 1971, 1972a), relational (Gilligan, 1993), role (Kelly, 1983; Turner, 1956, 1978; Zurcher, 1970, 1979), life cycle (Levinson et al, 1978, 1996), family life cycle (Rapoport & Rapoport, 1975), and role transition (Kelly, 1983) theories.

Résumé :

The role of innovation in the economy development is extremely significant. Within the framework of this work, the innovative activity of enterprises and its relation to corporate social responsibility (CSR) is of particular interest. This study is aimed at modeling the project management of corporate innovation activity on the basis of CSR. The results obtained by the author for the Russian economy suggest that there is a positive relationship between the level of innovative development and CSR, both in general and in terms of investments in the transformation of human capital. In this regard, the model of project management of corporate innovation activity based on CSR is proposed. Author suggests, that this model's implementation for companies is promising, since transition to such a model should be resulted in an increase in the innovation activity of companies, regions and the whole country, as well as an increase in the economic, social and organizational effectiveness of innovative activity.

Résumé :

Obesity is a highly visible yet neglected chronic health problem affecting developed and developing nations, particularly nations undergoing nutritional transition. The term ‘globesity’ has been coined to describe this international phenomenon, which primarily results from persistent energy imbalance typically characterized as reduced energy expenditure relative to energy intake. Conversely, disordered eating characterized by low energy intake, which is often paired with high levels of energy expenditure, are features of the opposite extreme to obesity and can manifest as eating disorders like anorexia nervosa or bulimia nervosa. Identification, treatment, and management of young people along the spectrum from frank eating disorders represents a persistent and growing health challenge. This chapter provides an overview of the range of factors contributing to inappropriate eating and activity disorders in childhood and adolescence, and how these problems might be managed.

Résumé :

Maintaining a healthy weight and engaging in regular physical activity are two health behaviors that can provide significant benefit to individuals with chronic pain. However, adhering to lifestyle programs that promote weight loss and/or physical activity can be challenging. A socioecological model of adherence to healthy lifestyle behaviors in individuals with pain can assist providers in understanding the physiological, intrapersonal/behavioral, and social/environmental factors that influence adherence. Providers can optimize adherence to weight loss by facilitating an effective patient–provider relationship, tailoring intervention approaches to meet a patient’s specific needs, and applying the Five A’s model of behavior change. Providers can support long-term engagement in physical activity by developing patient-centered exercise prescriptions based on an assessment of physical limitations, comorbidities, and age and to engage in shared decision-making to best account for patient preferences and barriers to exercise.

Résumé :

The school-to-work transition (STWT) is a major life event for those who must leave behind their lives as full-time students and begin new lives as a full-time employees. Although much has been written about the STWT, the role and importance of job search has often been neglected. At the same time, research on job search has tended to treat the job-search process as an independent and isolated activity. In this chapter, I describe an integrated model of job search within the context of the STWT. It shows that job search is preceded by a career-planning and development stage and followed by a work-adjustment stage. A successful STWT requires students to engage in a number of behaviors at each stage which should result in numerous outcomes that are necessary for a successful transition to the next stage. The model shows that job search is a critical part of the STWT that connects the career-planning and development stage to the work-adjustment stage. The chapter concludes with a discussion of the implications of the model for job search and STWT research and practice.

Résumé :

This chapter addresses the unique difficulties that disabled athletes face upon leaving sport. For instance, because athletes with disabilities tend to have less social connectedness than that of able-bodied athletes, further reducing it upon leaving a team may be problematic. Retiring athletes also experience numerous barriers to fitting in lifestyle physical activity and formal exercise. Hence they are at risk for overweight, obesity, and associated hypokinetic diseases. Athletes with disabilities are often intensely committed to sport, have strong and sometimes exclusive athletic identities, and disregard other important aspects of life. As a result, upon leaving sport they might experience a range of negative emotions, such as loss of self-esteem. At the same time, many athletes make the transition out of sport with relatively minor anguish. In some cases athletes look forward to leaving daily hard practices behind and embrace the opportunity to have more time to pursue other interests. For some athletes the difficulty of a transition is eased by remaining in sport as a coach or manager. Government programs are being developed for elite-level athletes , such as career assistance programs, to help athletes’ successful transition out of sport and into careers.

Résumé :

According to the visions and conceptualizations from philosophers to design thinkers such as Habermas, Maturana & Varela or Levin, the design applied to digital artifacts, products and services —due to the convergence of media, communication, deceives and technologies— is becoming even more a a bio-sphere —or better to say with the words of Vernadskij— a Noosphere. The cultural shifting is represented both in the process side and in the approach to the whole design materials and outcomes. On one hand, the organizational structure is moving from an “industrial” approach characterized by a waterfall-process —organized in subsequent of well-structured phases— to an iterative activity —that cycle among ideation, prototyping, testing assessing and redesign phases before to implement and release a project— to the agile and lean approach of the information-era in which the project itself persist constantly in a work-in-progress status —where upgrades and updates have replaced new releases. On the other hand, the object of the project itself is deeply changing according to a vision of a digital ecosystem and consequently to the design approach that is moving from a fixed —a two-dimensional page borrowed-model— to a liquid, then fluid solutions beside the divergences of media and devices and the convergence of user context and experience. Paraphrasing Maldonando we’re moving from virtual to real, from intangible to tangible, from the web to intelligent environment, both digital and physical. In this hybrid space the design process gambles his challenge to change process and purpose embracing both a traversal and a deep vertical approach to single elements of the eco-system and the eco-system in its wide complexity. Nevertheless this transition implies design to face with the challenges of emerging and upcoming phenomena: the designer education —skills, competences, methods— in an hybrid context, the anthropological mutation brought up by the new generation of digital natives and finally the social impact and emotional implication of the confluence of virtual and real experience —mediated by technologies— that people live in their daily life.DOI: http://dx.doi.org/10.4995/IFDP.2016.3013

Résumé :

A boundary layer transition model is presented which relates the near wall velocity fluctuations to the formation of turbulent spots. This model is used to determine the turbulent intermittency within a boundary layer integral code. Comparisons are made between the code predictions and established empirical correlations for the adverse pressure gradient transition experiments performed by Gostelow and co-workers. Similarly good accuracy was achieved by both the model and empirical correlation for start of transition. However, empirical correlations were less reliable than the model for predicting end of transition. The model was also able to predict the evolution of the measured intermittency considerably more accurately than the Narasimha empirical correlation. The current modelling approach is thus demonstrated to be more reliable than empirical correlation for the modelling of transitional boundary layers.

Texte intégral

Résumé :

Because many patients reduce exercise following outpatient cardiac rehabilitation (CR), we developed an intervention to assist with the transition and evaluated its feasibility and preliminary efficacy using a one-group pretest–posttest design. Five CR patients were enrolled ~1 month prior to CR discharge and provided an activity tracker. Each week during CR they received a summary of their physical activity and steps. Following CR discharge, participants received an individualized report that included their physical activity and step history, information on specific features of the activity tracker, and encouraging messages from former CR patients for each of the next 6 weeks. Mixed model trajectory analyses were used to test the intervention effect separately for active minutes and steps modeling three study phases: pre-intervention (day activity tracking began to CR discharge), intervention (day following CR discharge to day when final report sent), and maintenance (day following the final report to ~1 month later). Activity tracking was successfully deployed and, with weekly reports following CR, may offset the usual decline in physical activity. When weekly reports ceased, a decline in steps/day occurred. A scaled-up intervention with a more rigorous study design with sufficient sample size can evaluate this approach further.

The US Army Corps of Engineers, Louisville District, requested the support and assistance of the US Army Engineer Research and Development Center, Coastal and Hydraulics Laboratory (CHL), in the evaluation of the hydraulic performance of the replacement Outlet Works for Rough River Dam. To support the design effort, CHL constructed a 1:25.85 scale physical model. The proposed features of the model in the domain are the curved approach channel, intake structure, transition, curved conduit, stilling basin, concrete apron, and retreat channel. Tests performed to evaluate the hydraulic performance illuminated a few design concerns. To address these issues, several key design changes were made. These included the retreat channel slope, end sill design, and transition design.

Texte intégral

Résumé :

The present study analyzes the relation between energy transition and the job creation potential in Latin America. It capitalizes on companies' characteristics to infer potential hiring process drivers in forthcoming years. The analysis is based on an econometric model on cross-sectional data to explain the dependent variable "potential hiring rate" depending on the firm's size (based on the number of clients), area of activity or technology, employees' level of education, and the existence of labor policies. The data came from 338 companies interviewed, including generation, transmission, distribution, energy transition services, oil and gas, and construction companies in six Latin American Countries (Bolivia, Chile, Costa Rica, Mexico, Panama, and Uruguay). The econometric study focused on 135 companies that declared hiring new employees in the next year concerning the time they were interviewed. The results show that the smaller energy companies with a larger participation of a qualified workforce will tend to have a higher expected hiring rate in the forthcoming year, implying an inverse relationship between a firm's size and potential hiring rate. The model findings convey that as the workforce is compounded with more qualified employees, the higher the expansion of the company's labor force will be, particularly in renewable generation companies. There is an additional aspect worth considering about the factors behind the company's potential hiring rate, and it is the question of job quality. The results suggest that firms hiring more are those with a lower number of policies in place. It can be explained by the fact that more traditional companies tend to have better-established policies, such as hydrocarbon and utilities. These are not the companies with the highest increase in the workforce. This takeaway raises a discussion about whether a change in the job's quality is associated with the energy transition or if it is just associated with new entrants that will become traditional in the following years. Moreover, it also helps to explain some of the political economies of the labor market that may play a role in the energy transition process. Therefore, one of the present study's main takeaways is the need to analyze deeper and promote job quality in smaller energy companies.

Résumé :

The article studies the results of the research aimed at the improvement of the methodology of develop- ment of the health-preserving competence of a Physical Education teacher in conditions of post-graduate education on the basis of Nikolai Bernstein’s theory of movement construction using virtual reality technologies. Based on the use of AR/VR technologies a software application “Virtual Model Illustrating Nikolai Bernstein’s Theory of Movement Construction” was developed. The stated model is one of the tools of the “Methodology of development of the health preserving competence of a Physical Educa- tion teacher on the basis of Nikolai Bernstein’s theory of the levels of movement construction”. The experimental study determines that the application of the virtual model within the stated methodology is an effective tool for the development of the health preserving competence of a Physical Education teacher. The application of the virtual model allows the actualization of the health preserving, conceptual, gnoseological, biomechanical, inclusive, corrective potentials of Nikolai Bernstein’s theory of movement construction. The use of the virtual model presents the ways of targeted and meaningful use of Nikolai Bernstein’s theory of the levels of movement construction by a Physical Education teacher and the improvement of physical and recreational technologies and concrete physical exercises and movement modes. Due to the application of virtual reality tools, health-preserving, preventative, corrective and developmental strategies are being formed among which the significant ones are: “Application of syner- gistic movements to adaptation to movement activity, and recreation”, “Application of spatial movements for actualization of the orientation and search activities and development of spatial thinking”, “Use of movements with a complicated algorithm for intellect development”.

Texte intégral

Résumé :

Vegetation is believed to increase the stability of dunes during wave attack, but limited data is available. A physical model study was performed to evaluate changes in the dune stability with and without biomass, both above and belowground. The above and belowground biomass was modeled using wooden dowels and coir fibers, respectively. For both the collision and overwash storm impact regimes, the results of this study clearly demonstrate that the inclusion of biomass in the model dune reduces the erosion and overwash. The combination of both above and belowground biomass was the most effective at reducing erosion followed by belowground biomass, with aboveground biomass providing the smallest benefit regardless of the wave condition and water level. Additionally, the overwash of sediment and water was decreased with the inclusion of biomass, following the same trends as the erosion. As the dune eroded, the storm impact regime transitioned from collision to overwash. The inclusion of biomass delays this transition in storm impact regime, providing greater protection to coastal communities. This study highlights the need to consider dune vegetation for dune construction and coastal planning.

Résumé :

Objectives. To evaluate the effectiveness and harms of pain management programs that are based on the biopsychosocial model of care, particularly in the Medicare population. Data sources. Electronic databases (Ovid® MEDLINE®, PsycINFO®, CINAHL®, Cochrane Central Register of Controlled Trials, and Cochrane Database of Systematic Reviews) from 1989 to May 24, 2021; reference lists; and a Federal Register notice. Review methods. Given lack of consensus on terminology and program definition for pain management, we defined programs as integrated (based in and integrated with primary care) and comprehensive (referral based and separate from primary care) pain management programs (IPMPs and CPMPs). Using predefined criteria and dual review, we selected randomized controlled trials (RCTs) comparing IPMPs and CPMPs with usual care or waitlist, physical activity, pharmacologic therapy, and psychological therapy in patients with complex acute/subacute pain or chronic nonactive cancer pain. Patients needed to have access to medication support/review, psychological support, and physical function support in programs. Meta-analyses were conducted to improve estimate precision. We classified the magnitude of effects as small, moderate, or large based on predefined criteria. Strength of evidence (SOE) was assessed for the primary outcomes of pain, function, and change in opioid use. Results. We included 57 RCTs; 8 evaluated IPMPs and 49 evaluated CPMPs. Compared with usual care or waitlist, IPMPs were associated with small improvements in pain in the short and intermediate term (SOE: low) and in function in the short term (SOE: moderate), but there were no clear differences at other time points. CPMPs were associated with small improvements in pain immediately postintervention (SOE: moderate) but no differences in the short, intermediate, and long term (SOE: low); for function, improvements were moderate immediately postintervention and in the short term; there were no differences in the intermediate or long term (SOE: low at all time points). CPMPs were associated with small to moderate improvements in function and pain versus pharmacologic treatment alone at multiple time frames (SOE: moderate for function intermediate term; low for pain and function at all other times), and with small improvements in function but no improvements in pain in the short term when compared with physical activity alone (SOE: moderate). There were no differences between CPMPs and psychological therapy alone at any time (SOE: low). Serious harms were not reported, although evidence on harms was insufficient. The mean age was 57 years across IPMP RCTs and 45 years across CPMP RCTs. None of the trials specifically enrolled Medicare beneficiaries. Evidence on factors related to program structure, delivery, coordination, and components that may impact outcomes is sparse and there was substantial variability across studies on these factors. Conclusions. IPMPs and CPMPs may provide small to moderate improvements in function and small improvements in pain in patients with chronic pain compared with usual care. Formal pain management programs have not been widely implemented in the United States for general populations or the Medicare population. To the extent that programs are tailored to patients’ needs, our findings are potentially applicable to the Medicare population. Programs that address a range of biopsychosocial aspects of pain, tailor components to patient need, and coordinate care may be of particular importance in this population.

Teaching mechatronics provides for the meaningful integration of various disciplines of professional and practical training bachelors of electromechanics based on the concept of modeling and technological integration of various organizational forms and teaching methods based on the concept of mobility. Within this approach, the leading learning tools of bachelors of electromechanics are mobile Internet devices (MID) – a multimedia mobile devices that provide wireless access to information and communication Internet services for collecting, organizing, storing, processing, transmitting, presenting all kinds of messages and data. The authors reveals the main possibilities of using MID in learning to ensure equal access to education, personalized learning, instant feedback and evaluating learning outcomes, mobile learning, productive use of time spent in classrooms, creating mobile learning communities, support situated learning, development of continuous seamless learning, ensuring the gap between formal and informal learning, minimize educational disruption in conflict and disaster areas, assist learners with disabilities, improve the quality of the communication and the management of institution, and maximize the cost-efficiency. Bachelor of electromechanics competency in modeling of technical objects is a personal and vocational ability, which includes a system of knowledge, skills, experience in learning and research activities on modeling mechatronic systems and a positive value attitude towards it; bachelor of electromechanics should be ready and able to use methods and software/hardware modeling tools for processes analyzes, systems synthesis, evaluating their reliability and effectiveness for solving practical problems in professional field. The competency structure of the bachelor of electromechanics in the modeling of technical objects is reflected in three groups of competencies: general scientific, general professional and specialized professional. The implementation of the technique of using MID in learning bachelors of electromechanics in modeling of technical objects is the appropriate methodic of using, the component of which is partial methods for using MID in the formation of the general scientific component of the bachelor of electromechanics competency in modeling of technical objects, are disclosed by example academic disciplines “Higher mathematics”, “Computers and programming”, “Engineering mechanics”, “Electrical machines”. The leading tools of formation of the general scientific component of bachelor in electromechanics competency in modeling of technical objects are augmented reality mobile tools (to visualize the objects’ structure and modeling results), mobile computer mathematical systems (universal tools used at all stages of modeling learning), cloud based spreadsheets (as modeling tools) and text editors (to make the program description of model), mobile computer-aided design systems (to create and view the physical properties of models of technical objects) and mobile communication tools (to organize a joint activity in modeling).

Résumé :

The COP9 signalosome (CSN) is an eight-subunit protein complex that is highly conserved among eukaryotes. Genetic analysis of the signalosome in the plant model species Arabidopsis thaliana has shown that the signalosome is a repressor of light dependent seedling development as mutant Arabidopsis seedlings that lack this complex develop in complete darkness as if exposed to light. These mutant plants die following the seedling stage, even when exposed to light, indicating that the COP9 signalosome also has a central role in the regulation of normal photomorphogenic development. The biochemical mode of action of the signalosome and its position in eukaryotic cell signaling pathways is a matter of controversy and ongoing investigation, and recent results place the CSN at the juncture of kinase signaling pathways and ubiquitin-mediated protein degradation. We have shown that one of the many CSN functions may relate to the regulation of translation through the interaction of the CSN with its related complex, eukaryotic initiation factor (eIF3). While we have established a physical connection between eIF3 subunits and CSN subunits, the physiological and developmental significance of this interaction is still unknown. In an effort to understand the biochemical activity of the signalosome, and its role in regulating translation, we originally proposed to dissect the contribution of "h" subunit of eIF3 (eIF3h) along the following specific aims: (i) Isolation and phenotypic characterization of an Arabidopsis loss-of-function allele for eIF3h from insertional mutagenesis libraries; (ii) Creation of designed gain and loss of function alleles for eIF3h on the basis of its nucleocytoplasmic distribution and its yeast-two-hybrid interactions with other eIF3 and signalosome partner proteins; (iii) Determining the contribution of eIF3h and its interaction with the signalosome by expressing specific mutants of eIF3h in the eIF3h- loss-of function background. During the course of the research, these goals were modified to include examining the genetic interaction between csn and eif3h mutations. More importantly, we extended our effort toward the genetic analysis of mutations in the eIF3e subunit, which also interacts with the CSN. Through the course of this research program we have made several critical scientific discoveries, all concerned with the apparent diametrically opposed roles of eIF3h and eIF3e. We showed that: 1) While eIF3e is essential for growth and development, eIF3h is not essential for growth or basal translation; 2) While eIF3e has a negative role in translational regulation, eIF3h is positively required for efficient translation of transcripts with complex 5' UTR sequences; 3) Over-accumulation of eIF3e and loss-of-function of eIF3h both lead to cop phenotypes in dark-grown seedlings. These results were published in one publication (Kim et al., Plant Cell 2004) and in a second manuscript currently in revision for Embo J. Are results have led to a paradigm shift in translation research – eIF3 is now viewed in all systems as a dynamic entity that contains regulatory subuits that affect translational efficiency. In the long-term agronomic outlook, the proposed research has implications that may be far reaching. Many important plant processes, including developmental and physiological responses to light, abiotic stress, photosynthate, and hormones operate in part by modulating protein translation [23, 24, 40, 75]. Translational regulation is slowly coming of age as a mechanism for regulating foreign gene expression in plants, beginning with translational enhancers [84, 85] and more recently, coordinating the expression of multiple transgenes using internal ribosome entry sites. Our contribution to understanding the molecular mode of action of a protein complex as fundamental as eIF3 is likely to lead to advances that will be applicable in the foreseeable future.
