    2012-01-01

    Leadership and how it is developed have become a top priority for almost all organisations, particularly schools and business organisations, to survive and secure growth (Bolden, 2004). Equally, the concept of partnership has become a panacea for solving complex and ‘wicked’ problems in diverse organisations (Armistead, 2007). This study therefore investigates how school-business partnerships could serve as alternative means for organisational leadership development. The study is principally ...

  5. Stretching between learning and accountability: Experiences of South African non-governmental organisations

    While learning and accountability are two fundamental purposes of M&E, in practice NGOs often perceive donor accountability as the only function of their organisation’s M&E system. Learning through meaningful monitoring of actions is a necessary process to satisfy effective functioning of organisations working on social change. The article is based on action research, which included qualitative methods such as case studies, focus group interview(s, semi-structured interviews and questionnaires with participating organisations from an 18-month Monitoring and Evaluation Capacity Development Programme of the Community Development Resource Association, which involved nine South African NGOs. Organisations benefited from the programme through peer learning, consulting and research linked to the programme. The research revealed that NGOs have a perception of M&E as an accountability procedure that has been imposed on them by donor communities and are resistant to it as well as to rigid data collection.Organisations require specific capacities to realise their power and to be able to negotiate more developmental approaches to M&E within their organisations and with donors. The model is suggested that fosters learning in M&E systems and includes two interlinked processes: self-awareness (a sense of core organisational values and intuitive ability and awareness about the outside world and the effects of organisations’ work. The model for M&E systems can be explored further and help those organisations who are working towards better balance between learning and accountability.

  8. Development of the school organisational health questionnaire: a measure for assessing teacher morale and school organisational climate.

    2000-06-01

    A growing body of empirical evidence suggests that organisational factors are more important than classroom specific issues in determining teacher morale. Accordingly, it is necessary to have available measures that accurately assess morale, as well as the organisational factors that are likely to underpin the experience of morale. Three studies were conducted with the aim of developing a psychometrically sound questionnaire that could be used to assess teacher morale and various dimensions of school organisational climate. A total of 1,520 teachers from 18 primary and 26 secondary schools in the Australian state of Victoria agreed to participate in three separate studies (N = 615, 342 and 563 in Studies 1, 2 and 3, respectively) that were used to develop the questionnaire. The demographic profile of the teachers was similar to that found in the Department as a whole. All teaching staff in the participating schools were asked to complete a self-report questionnaire as part of the evaluation of an organisational development programme. A series of exploratory and confirmatory factor analyses were used to establish the questionnaire's factor structure, and correlation analyses were used to examine the questionnaire's convergent and discriminant validity. The three studies resulted in the 54-item School Organisational Health Questionnaire that measures teacher morale and 11 separate dimensions of school organisational climate: appraisal and recognition, curriculum coordination, effective discipline policy, excessive work demands, goal congruence, participative decision-making, professional growth, professional interaction, role clarity, student orientation, and supportive leadership.

    Full Text Available The paper presents some organisational outcomes in school management that are strongly interrelated, and leadership which has a significant impact on them. Considering the fact that the school is a non-profit organisation with a specific social significance, the aim of the research was to determine how to improve the results of the school management, or to determine how to improve the management of the school by the school principal, and thus to improve key organisational outcomes: school quality, job satisfaction, organisational (school culture and work motivation. The survey was conducted during the first half of 2014 (January, February, March in 23 secondary schools in Una-Sana Canton (B and H, by the method of survey and interviewing, using the questionnaire as an instrument of scientific research. The above outcomes significantly affect key organisational outcomes of the educational process, pupils' achievement, which are measured by their success in learning and behaviour.

  11. [Subtainable health promotion via organisational development--a model project for teachers in professional training schools].

    Science.gov (United States)

    Schumacher, L; Nieskens, B; Bräuer, H; Sieland, B

    2005-02-01

    The goal of this project is the development, implementation and evaluation of a concept designed for sustainable health promotion among occupational and trade school teachers. We assume that for sustainable health promotion -- along with a behavioral prevention program -- a change is necessary in the structure, as well as, the working and communication processes within schools. The realization of early teacher participation and self regulated cooperative groups initiates comprehensive and goal-oriented developmental processes in the project schools. The organizational development process was accomplished in the following way: At the beginning we conducted a diagnosis of school-specific and individual health risks and the resources available to the project schools. The results were reported for both the individual and for the teacher group. This was intended to clarify the potential for improvement and, thus, strengthen the teachers' motivation toward processes of change. Following the diagnosis, the teachers chose areas of stress-related strain and then worked in groups to develop and implement behaviour and working condition-oriented intervention strategies for health promotion. The diagnosis results confirm the necessity of school-specific health promotion: the schools demonstrate very different demand and resource profiles. Furthermore, is has become evident that the central success factor for health promotion in schools is the teachers' willingness for change. The individual and group reports of the diagnosis results seem to have made clear how essential individual and organisational changes are.

  13. Educators and the quality of their work environment: an analysis of the organisational climate in primary schools

    Directory of Open Access Journals (Sweden)

    D Vos

    2012-01-01

    Full Text Available The prevalent organisational climate in primary schools in the North West Province was determined in order to formulate management strategies to increase the organisational climate. For this purpose, a quantitative research method, founded in post-positivistic points of departure, was applied. In the process, the Organizational Climate Description Questionnaire - Rutgers Elementary (OCDQ-RE was applied in order to determine the behaviour of principals and school educators. The investigation indicated that the behaviour of the principals and that of the educators contributed only to an average degree to the establishment of a more effective organisational climate in the primary schools investigated. Furthermore the exploratory and confirmatory factor analyses indicated that certain items in the original climate questionnaire, which were grouped in the directive behaviour of the principal, were viewed by the respondents in South Africa as supportive but, in some instances, also as restrictive.

    Full Text Available Abstract Background Many countries have recently expanded their childhood immunisation programmes. Schools are an increasingly attractive setting for delivery of these new immunisations because of their ability to reach large numbers of children in a short period of time. However, there are organisational challenges to delivery of large-scale vaccination programmes in schools. Understanding the facilitators and barriers is important for improving the delivery of future school-based vaccination programmes. Methods We undertook a systematic review of evidence on school-based vaccination programmes in order to understand the influence of organisational factors on the delivery of programmes. Our eligibility criteria were studies that (1 focused on childhood or adolescent vaccination programmes delivered in schools; (2 considered organisational factors that influenced the preparation or delivery of programmes; (3 were conducted in a developed or high-income country; and (4 had been peer reviewed. We searched for articles published in English between 2000 and 2015 using MEDLINE and HMIC electronic databases. Additional studies were identified by searching the Cochrane Library and bibliographies. We extracted data from the studies, assessed quality and the risk of bias, and categorised findings using a thematic framework of eight organisational factors. Results We found that most of the recent published literature is from the United States and is concerned with the delivery of pandemic or seasonal flu vaccination programmes at a regional (state or local level. We found that the literature is largely descriptive and not informed by the use of theory. Despite this, we identified common factors that influence the implementation of programmes. These factors included programme leadership and governance, organisational models and institutional relationships, workforce capacity and roles particularly concerning the school nurse, communication with parents and

    A proportion of newly qualified doctors report feeling unprepared to manage patients with palliative care and end-of-life needs. This may be related to barriers within their institution during undergraduate training. Information is limited regarding the current organisation of palliative care teaching across UK medical schools. To investigate the evolution and structure of palliative care teaching at UK medical schools. Anonymised, web-based questionnaire. Settings/participants: Results were obtained from palliative care course organisers at all 30 UK medical schools. The palliative care course was established through active planning (13/30, 43%), ad hoc development (10, 33%) or combination of approaches (7, 23%). The place of palliative care teaching within the curriculum varied. A student-selected palliative care component was offered by 29/30 (97%). All medical schools sought student feedback. The course was reviewed in 26/30 (87%) but not in 4. Similarly, a course organiser was responsible for the palliative care programme in 26/30 but not in 4. A total of 22 respondents spent a mean of 3.9 h (median 2.5)/week in supporting/delivering palliative care education (organisers received titular recognition in 18/27 (67%; no title 9 (33%); unknown 3 (11%)). An academic department of Palliative Medicine existed in 12/30 (40%) medical schools. Funding was not universally transparent. Palliative care teaching was associated with some form of funding in 20/30 (66%). Development, organisation, course evaluation and funding for palliative care teaching at UK medical schools are variable. This may have implications for delivery of effective palliative care education for medical students.

  12. Knotting in stretched polygons

    Rensburg, E J Janse van; Orlandini, E; Tesi, M C; Whittington, S G

    2008-01-01

    The knotting in a lattice polygon model of ring polymers is examined when a stretching force is applied to the polygon. By examining the incidence of cut-planes in the polygon, we prove a pattern theorem in the stretching regime for large applied forces. This theorem can be used to examine the incidence of entanglements such as knotting and writhing. In particular, we prove that for arbitrarily large positive, but finite, values of the stretching force, the probability that a stretched polygon is knotted approaches 1 as the length of the polygon increases. In the case of writhing, we prove that for stretched polygons of length n, and for every function f(n)=o(√n), the probability that the absolute value of the mean writhe is less than f(n) approaches 0 as n → ∞, for sufficiently large values of the applied stretching force

    Background: In Sweden, as in many other countries, there has been a succession of trends in the organisation of health care and other welfare services. These trends have had different implications for the integration of services in the health and welfare system. Aims: One aim is to discuss...... the implications of different organisational trends for the integration of health and welfare services. Another aim is to introduce a Swedish model of financial coordination as a flexible way to organise integration. Organisational trends: In the 1960’s there was an expansion of health and welfare services leading...... an increasing lack of integration in the health and welfare system. In the 2000’s, there has been a re-centralisation through mergers of hospitals, regions and state agencies. It has become clear, however, that mergers do not promote integration but rather increase the bureaucratisation of the system. Model...

    To assess the extent to which participation in organised physical activity in the school or community outside school hours and neighbourhood play was associated with children's physical activity and sedentary time. Cross-sectional study. Children were recruited from 47 state-funded primary schools in South West England. 1223 children aged 8-9 years old. Accelerometer-assessed moderate-to-vigorous-intensity physical activity (MVPA) and sedentary time. Children wore an accelerometer, and the mean minutes of MVPA and sedentary time per day were derived. Children reported their attendance at organised physical activity in the school or community outside school hours and neighbourhood play using a piloted questionnaire. Cross-sectional linear and logistic regression were used to examine if attendance frequency at each setting (and all settings combined) was associated with MVPA and sedentary time. Multiple imputation methods were used to account for missing data and increase sample size. Children who attended clubs at school 3-4 days per week obtained an average of 7.58 (95% CI 2.7 to 12.4) more minutes of MVPA per day than children who never attended. Participation in the three other non-school-based activities was similarly associated with MVPA. Evidence for associations with sedentary time was generally weaker. Associations were similar in girls and boys. When the four different contexts were combined, each additional one to two activities participated in per week increased participants' odds (OR: 1.18, 95% CI 1.12 to 1.25) of meeting the government recommendations for 60 min of MVPA per day. Participating in organised physical activity at school and in the community is associated with greater physical activity and reduced sedentary time among both boys and girls. All four types of activity contribute to overall physical activity, which provides parents with a range of settings in which to help their child be active. © Article author(s) (or their employer

  19. Educating for Peace: The Role and Impact of International Organisations in Interwar and Post-War Danish School Experiments, 1918–1975

    2015-11-01

    Full Text Available In the aftermath of the two world wars, strong international networks and organisations manifested themselves with promotion of peace through education on their agenda. Danish pedagogical experiments and experimental schools were strongly influenced by these trends and played a role in subsequent school practices and policies. Drawing on the notions of “the transnational” and “trading spaces” as well as the theoretical concepts of transfer, translation, and transformation, this article addresses the following research question: How were international ideas, knowledge and practice of promoting peace through education transferred, translated, and transformed in Danish school experiments in interwar and post-war scenarios? In exploring this question, the article uses transnational and Danish archival sources as well as journals and reports linked to the Danish progressive education movement. Thus, the article contributes to our understanding of the entanglements of educational ideas and to how trends of internationalisation and globalisation work.

    Full Text Available A vast array of economical, social, political, cultural and other factors influences the transformed role of learning and education in the society, as well as the functioning of local community and its social and communication patterns. The influences which are manifested as global problems can only be successfully solved on the level of local community. Analogously with the society in general, there is a great need of transforming a local community into a learning, flexible and interconnected environment which takes into account different interests, wishes and needs regarding learning and being active. The fundamental answer to changes is the strategy of lifelong learning and education which requires reorganisation of all walks of life (work, free time, family, mass media, culture, sport, education and transforming of organisations into learning organisations. With learning society based on networks of knowledge individuals are turning into learning individuals, and organisations into learning organisations; people who learn take the responsibility of their progress, learning denotes partnership among learning people, teachers, parents, employers and local community, so that they work together to achieve better results.

    2016-04-01

    Full Text Available Background: Healthy individuals, to ease and accomplish their activities of daily living they need flexible body without any tightness in the muscles, particularly those used for a definite function. Cooling soft tissues in a lengthened position after stretching has been shown to promote more lasting increases in soft tissue length and minimize post stretch muscle soreness. There are less documented studies which compared modified proprioceptive neuromuscular facilitation (PNF stretch over passive manual stretch with cold application commonly after the interventions. Methods: Thirty high school going healthy students were divided into two groups- Group I received Passive Manual stretching (n=15 and Group II received modified PNF stretching (n=15 and both groups received cold application after the interventions for 10 minutes commonly for 5 days. ROM was taken on day 1, day 5 and day 7. Results: After day 7, Group II with Modified PNF stretching along with cold application showed a significant increase in range of motion tested with active knee extension test (AKET. Conclusion: Modified PNF stretching is considered to be the effective intervention in increasing and maintaining ROM in AKET over passive manual stretching with cold applications commonly after the interventions.

    Barton, Michael; Kosinka, Jin; Calo, Victor M.

    2015-01-01

    We study the problem of finding stretch-minimising stream surfaces in a divergence-free vector field. These surfaces are generated by motions of seed curves that propagate through the field in a stretch minimising manner, i.e., they move without stretching or shrinking, preserving the length of their arbitrary arc. In general fields, such curves may not exist. How-ever, the divergence-free constraint gives rise to these 'stretch-free' curves that are locally arc-length preserving when infinitesimally propagated. Several families of stretch-free curves are identified and used as initial guesses for stream surface generation. These surfaces are subsequently globally optimised to obtain the best stretch-minimising stream surfaces in a given divergence-free vector field. Our algorithm was tested on benchmark datasets, proving its applicability to incompressible fluid flow simulations, where our stretch-minimising stream surfaces realistically reflect the flow of a flexible univariate object. © 2015 Elsevier Inc.

    2016-05-01

    Full Text Available Background: In 2007, the Tanzanian government called for improvements in its primary health care services. Part of this initiative was to accelerate the training rate for nurses qualified to work in rural areas. The aim of this study was to reflect on the issues experienced whilst establishing and implementing a faith-based organisation (FBO nursing school and make recommendations for other similar initiatives. Design: This paper describes an auto-ethnographic case study design to identify the key difficulties involved with establishing and implementing a new nursing school, and which factors helped the project achieve its goals. Results: Six themes emerged from the experiences that shaped the course of the project: 1 Motivation can be sustained if the rationale of the project is in line with its aims. Indeed, the project's primary health care focus was to strengthen the nursing workforce and build a public–private partnership with an FBO. All these were strengths, which helped in the midst of all the uncertainties. 2 Communication was an important and often underrated factor for all types of development projects. 3 Managing the unknown and 4 managing expectations characterised the project inception.

  5. Efficacy of hamstring stretching programs in schoolchildren. A systematic review

    Directory of Open Access Journals (Sweden)

    Carlos-Alberto BECERRA FERNANDEZ

    2017-03-01

    Full Text Available The main purpose of the present review was to examine the scientific literature on the effects of physical education-based stretching programs on hamstring extensibility in schoolchildren aged 6-11 years. For this purpose relevant studies were searched from ten electronic databases dated up through May 2015. Of the 25 potentially relevant articles identified and retrieved for more detailed evaluation, only eight studies were included in the present review because they met the inclusion criteria. The overall results showed that incorporating hamstring stretching as a part of physical education classes produces a significant improvement in the scores of the tests: straight leg raise and classic sit-and-reach, for the experimental groups, but not for control groups. Stretching programs can be included in Physical Education classes, specifically during the warm-up and the cool down periods in order to improve hamstring extensibility. Although it seems that the stretching exercises in the warm-up period could be less effective in gaining flexibility in school children. Studies that use a stretching volume between 4 and 7 minutes per session and 2-4 training classes per week, obtain statistically significant improvements on the levels of hamstring flexibility in the experimental groups. However, after a five-week detraining period, children revert back to their initial flexibility levels. Therefore, it seems appropriate that physical education teachers should implement stretching programs to improve the students´ flexibility during the Physical Education classes.

    The purpose of this study was to explore the relationship between organisational support, organisational identification, and organisational citizenship behaviour and the predictors of organisational citizenship behaviour in Taiwanese male nurses. The turnover rate among male nurses is twice that of female nurses. Organisational citizenship behaviour is the predictor of turnover intention. Little information is available on the relationship between organisational support, organisational identification and organisational citizenship behaviour, particularly for male nurses. Data were collected in 2010 from a questionnaire mailed to 167 male nurses in Taiwan. A cross-sectional survey with simple sampling was used in this study. The results showed that organisational identification and organisational support were correlated with organisational citizenship behaviour. Organisational distinctiveness, organisational support of work conditions and the type of organisation were the main predictors of organisational citizenship behaviour. Together they accounted for 40.7% of the total variation in organisational citizenship behaviour. Organisational distinctiveness was the most critical predictor, accounting for 29.6% of the variation. Organisational support and organisational identification have positive relationships with organisational behaviour. Organisational distinctiveness is an important factor in explaining organisational citizenship behaviour in male nurses. This finding provides concrete directions for managers to follow when providing organisational identification, in particular, the organisational distinctiveness will help male nurses to display increasingly more organisational citizenship behaviour. © 2012 John Wiley & Sons Ltd.

    Beardsley, Brooke; Rassl, Doris

    2013-10-01

    Organising pneumonia (otherwise referred to as bronchiolitis obliterans organising pneumonia) is characterised histologically by plugs of granulation tissue, which are present predominantly within small airways, alveolar ducts and peri-bronchiolar alveoli. This pattern is not specific for any disorder or cause, but is one type of inflammatory response to pulmonary injury, which may be seen in a wide variety of clinical conditions. Typically, organising pneumonia responds very well to corticosteroid treatment; however, a small percentage of patients appear to develop progressive fibrosis.

    Observing non-repetitive and statistically rare signals that occur on short timescales requires fast real-time measurements that exceed the speed, precision and record length of conventional digitizers. Photonic time stretch is a data acquisition method that overcomes the speed limitations of electronic digitizers and enables continuous ultrafast single-shot spectroscopy, imaging, reflectometry, terahertz and other measurements at refresh rates reaching billions of frames per second with non-stop recording spanning trillions of consecutive frames. The technology has opened a new frontier in measurement science unveiling transient phenomena in nonlinear dynamics such as optical rogue waves and soliton molecules, and in relativistic electron bunching. It has also created a new class of instruments that have been integrated with artificial intelligence for sensing and biomedical diagnostics. We review the fundamental principles and applications of this emerging field for continuous phase and amplitude characterization at extremely high repetition rates via time-stretch spectral interferometry.

    2011-03-01

    Despite more than a decade of experiments on single biomolecule manipulation, mechanical properties of only several scores of proteins have been measured. A characteristic scale of the force of resistance to stretching, Fmax , has been found to range between ~ 10 and 480 pN. The Biomolecule Stretching Data Base (BSDB) described here provides information about expected values of Fmax for, currently, 17 134 proteins. The values and other characteristics of the unfolding proces, including the nature of identified mechanical clamps, are available at www://info.ifpan.edu.pl/BSDB/. They have been obtained through simulations within a structure-based model which correlates satisfactorily with the available experimental data on stretching. BSDB also lists experimental data and results of the existing all-atom simulations. The database offers a Protein-Data-Bank-wide guide to mechano-stability of proteins. Its description is provided by a forthcoming Nucleic Acids Research paper. Supported by EC FUNMOL project FP7-NMP-2007-SMALL-1, and European Regional Development Fund: Innovative Economy (POIG.01.01.02-00-008/08).

    Undesirable detachment or stretching of coils within the parent artery during aneurysm embolization can be related with thrombus formation, which can be caused occlusion of parent artery or embolic event(s). To escape from this situation, several rescue methods have been reported. A case with undesirably stretched coil in which another rescue method was used, is presented. When the stretched coil is still located in the coil delivery microcatheter, the stretched coil can be removed safely using a snare and a handmade monorail microcatheter. After a snare is lodged in the handmade monorail microcatheter, the snare is introduced over the coil delivery micorcatheter and located in the distal part of the stretched coil. After then, the handmade monorail microcatheter captures the stretched coil and the snare as one unit. This technique using a handmade monorail microcatheter and a snare can be a good rescue modality for the undesirably stretched coil, still remained within the coil delivery microcatheter.

    2009-04-01

    While this article mainly applies to practitioners who have responsibilities for leading teams or supervising practitioners, many of the skills and tools described here may also apply to students or junior practitioners. The purpose of this article is to highlight some of the main points about organisation, some of the organisational skills and tools that are available, and some examples of how these skills and tools can be used to make practitioners more effective at organising their workload. It is important to realise that organising work and doing work are two completely different things and shouldn't be mixed up. For example, it would be very difficult to start organising work in the middle of a busy operating list: the organisation of the work must come before the work starts and therefore preparation is often an important first step in organising work. As such, some of the tools and skills described in this article may need to be used hours or even days prior to the actual work taking place.

During the last decade various techniques have emerged allowing micromanipulation of single molecules and simultaneous measurements of their elasticity. Using such techniques, it has been possible to investigate some of the interactions playing a role in biology. We shall first review the simplest case of a non-interacting polymer and then present the structural transitions in DNA, RNA and proteins that have been studied by single-molecule techniques. We shall explain how these techniques permit a new approach to the protein folding/unfolding transition

    Full Text Available Organisational culture discourse mandates a linear approach of diagnosis, measurement and gap analysis as standard practice in relation to most culture change initiatives. Therefore, a problem solving framework geared toward “fixing�? and/or realigning an organisation’s culture is usually prescribed. The traditional problem solving model seeks to identify gaps between current and desired organisational cultural states, inhibiting the discovery of an organisation’s unique values and strengths, namely its cultural capital. In pursuit of discovering and leveraging organisational cultural capital, a descriptive case study is used to show how an Appreciative Inquiry process can rejuvenate the spirit of an organisation as a system-wide inquiry mobilises a workforce toward a shared vision.

    2017-11-01

    The surface energy of solid interfaces plays a central role in wetting, as they dictate the liquid contact angle. Yet, it has been challenging to measure the solid surface energies independently, without making use of Young's law. Here we present Molecular Dynamics (MD) simulations by which we measure the surface properties for all interfaces, including the solids. We observe change in contact angles upon stretching the solid substrates, showing that the surface energy is actually strain dependent. This is clear evidence of the so-called Shuttleworth effect, making it necessary to distinguish surface energy from surface tension. We discuss how this effect gives rise to a new class of elasto-capillary phenomena. ERC Consolidator Grant No. 616918.

  11. Strategy as stretch and leverage.

    Science.gov (United States)

    Hamel, G; Prahalad, C K

    1993-01-01

    Global competition is not just product versus product or company versus company. It is mind-set versus mind-set. Driven to understand the dynamics of competition, we have learned a lot about what makes one company more successful than another. But to find the root of competitiveness--to understand why some companies create new forms of competitive advantage while others watch and follow--we must look at strategic mind-sets. For many managers, "being strategic" means pursuing opportunities that fit the company's resources. This approach is not wrong, Gary Hamel and C.K. Prahalad contend, but it obscures an approach in which "stretch" supplements fit and being strategic means creating a chasm between ambition and resources. Toyota, CNN, British Airways, Sony, and others all displaced competitors with stronger reputations and deeper pockets. Their secret? In each case, the winner had greater ambition than its well-endowed rivals. Winners also find less resource-intensive ways of achieving their ambitious goals. This is where leverage complements the strategic allocation of resources. Managers at competitive companies can get a bigger bang for their buck in five basic ways: by concentrating resources around strategic goals; by accumulating resources more efficiently; by complementing one kind of resource with another; by conserving resources whenever they can; and by recovering resources from the market-place as quickly as possible. As recent competitive battles have demonstrated, abundant resources can't guarantee continued industry leadership.(ABSTRACT TRUNCATED AT 250 WORDS)

    2015-01-01

    Definitions of social accountability describe the obligation of medical schools to direct education, research and service activities towards addressing the priority health concerns of the population they serve. While such statements give some direction as to how the goal might be reached, it does not identify what factors might facilitate or hinder its achievement. This study set out to identify and explore enablers and barriers influencing the incorporation of social accountability values into medical schools. Semi structured interviews of fourteen senior staff in Bar Ilan and Leeds medical schools were undertaken following a literature review. Participants were recruited by purposive sampling in order to identify factors perceived to play a part in the workings of each institution. Academic prestige was seen as a key barrier that was dependent on research priorities and student selection. The role of champions was considered to be vital to tackle staff perceptions and facilitate progress. Including practical community experience for students was felt to be a relevant way in which the curriculum could be designed through engagement with local partners. Successful adoption of social accountability values requires addressing concerns around potential negative impacts on academic prestige and standards. Identifying and supporting credible social accountability champions to disseminate the values throughout research and education departments in medical and other faculties is also necessary, including mapping onto existing work streams and research agendas. Demonstrating the contribution the institution can make to local health improvement and regional development by a consideration of its economic footprint may also be valuable.

    Research supports the use of preactivity warm-up and stretching, and the purpose of this study was to determine whether college football programs follow these guidelines. Questionnaires designed to gather demographic, professional, and educational information, as well as specific pre- and postactivity practices, were distributed via e-mail to midwestern collegiate programs from NCAA Division I and III conferences. Twenty-three male coaches (12 from Division IA schools and 11 from Division III schools) participated in the study. Division I schools employed certified strength coaches (CSCS; 100%), whereas Division III schools used mainly strength coordinators (73%), with only 25% CSCS. All programs used preactivity warm-up, with the majority employing 2-5 minutes of sport-specific jogging/running drills. Pre stretching (5-10 minutes) was performed in 19 programs (91%), with 2 (9%) performing no pre stretching. Thirteen respondents used a combination of static/proprioceptive neuromuscular facilitation/ballistic and dynamic flexibility, 5 used only dynamic flexibility, and 1 used only static stretching. All 12 Division I coaches used stretching, whereas only 9 of the 11 Division III coaches did (p = 0.22). The results indicate that younger coaches did not use pre stretching (p = 0.30). The majority of the coaches indicated that they did use post stretching, with 11 of the 12 Division I coaches using stretching, whereas only 5 of the 11 Division III coaches used stretching postactivity (p = 0.027). Divisional results show that the majority of Division I coaches use static-style stretching (p = 0.049). The results of this study indicate that divisional status, age, and certification may influence how well research guidelines are followed. Further research is needed to delineate how these factors affect coaching decisions.

  15. Stretch due to Penile Prosthesis Reservoir Migration

    Full Text Available A 43-year old patient presented to the emergency department with stretch, due to impossible deflation of the penile prosthesis, 4 years after successful implant. A CT-scan showed migration of the reservoir to the left rectus abdominis muscle. Refilling of the reservoir was inhibited by muscular compression, causing stretch. Removal and replacement of the reservoir was performed, after which the prosthesis was well-functioning again. Migration of the penile prosthesis reservoir is extremely rare but can cause several complications, such as stretch.

    2018-04-01

    Different stretching strategies and protocols are widely used to improve flexibility or maintain health, acting on the muscle tendon-unit, in order to improve the range of motion (ROM) of the joints. This review aims to evaluate the current body of literature in order to understand the relation between stretching typology and ROM, and secondly to evaluate if a relation exists between stretching volume (either as a single training session, weekly training and weekly frequency) and ROM, after long-term stretching. Twenty-three articles were considered eligible and included in the quantitative synthesis. All stretching typologies showed ROM improvements over a long-term period, however the static protocols showed significant gains (p<0.05) when compared to the ballistic or PNF protocols. Time spent stretching per week seems fundamental to elicit range of movement improvements when stretches are applied for at least or more than 5 min, whereas the time spent stretching within a single session does not seem to have significant effects for ROM gains. Weekly frequency is positively associated to ROM. Evaluated data indicates that performing stretching at least 5 days a week for at least 5 min per week using static stretching may be beneficial to promote ROM improvements. © Georg Thieme Verlag KG Stuttgart · New York.

    2000-01-01

    Cellular solids can deform by either the bending or stretching of the cell walls. While most cellular solids are bending-dominated, those that are stretching-dominated are much more weight-efficient for structural applications. In this study we have investigated the topological criteria that dictate the deformation mechanism of a cellular solid by analysing the rigidity (or otherwise) of pin-jointed frameworks comprising inextensional struts. We show that the minimum node connectivity for a special class of lattice structured materials to be stretching-dominated is 6 for 2D foams and 12 for 3D foams. Similarly, sandwich plates comprising of truss cores faced with planar trusses require a minimum node connectivity of 9 to undergo stretching-dominated deformation for all loading states. (author)

    Full Text Available Virtual organisation is a strategic paradigm that is centred on the use of information and ICT to create value. Virtual organisation is presented as a metamanagement strategy that has application in all value oriented organisations. Within the concept of Virtual organisation, the business model is an ICT based construct that bridges and integrates enterprise strategic and operational concerns. Firms try to ameliorate the impacts of risk and product complexity by forming alliances and partnerships with others to spread the risk of new products and new ventures and to increase organisational competence. The result is a networked virtual organization.

The study was carried out on pupils between 5-15 years old in a school and kindergarden belonging to the Turkish Chamber of Commerce and Stock Exchange Organization in Van City between November-December 2007. The hair of 863 pupils (especially the neck and the back of head areas), 385 girls and 478 boys, were examined for eggs, nymphs and adults of P. h. capitis. A questionnaire was given to the pupils, which was collected the following day. Lice and their eggs/nits, which were removed from the head of children were transferred to a bottle containing 5% glycerin in 70% ethyl alcohol. Later they were sent to the Parasitology Laboratory of the Health Research and Training Hospital of Yüzüncü Yıl University. Eggs/nits were found in 164 (42.6%) of the girls and in 34 (7.1%) of the boys (overall 198 (22.9%) infested pupils). The prevalence of P. h. capitis was high, especially in girls. The infestation rates observed and the evaluation of the questionnaire showed that there is a statistically significant relationships between pediculosis capitis and sex, level of family income, education level of the mother, number of baths taken per weekly, number of family members living in the same home, room number per capita, and hair length (p0.05).

    We examine the topological entanglements of polygons confined to a lattice tube and under the influence of an external tensile force f. The existence of the limiting free energy for these so-called stretched polygons is proved and then, using transfer matrix arguments, a pattern theorem for stretched polygons is proved. Note that the tube constraint allows us to prove a pattern theorem for any arbitrary value of f, while without the tube constraint it has so far only been proved for large values of f. The stretched polygon pattern theorem is used first to show that the average span per edge of a randomly chosen n-edge stretched polygon approaches a positive value, non-decreasing in f, as n {yields} {infinity}. We then show that the knotting probability of an n-edge stretched polygon confined to a tube goes to one exponentially as n {yields} {infinity}. Thus as n {yields} {infinity} when polygons are influenced by a force f, no matter its strength or direction, topological entanglements, as defined by knotting, occur with high probability.

  20. Influence of the stretch wrapping process on the mechanical behavior of a stretch film

    Klein, Daniel; Stommel, Markus; Zimmer, Johannes

    2018-05-01

    Lightweight construction is an ongoing task in packaging development. Consequently, the stability of packages during transport is gaining importance. This study contributes to the optimization of lightweight packaging concepts regarding their stability. A very widespread packaging concept is the distribution of goods on a pallet whereas a Polyethylene (PE) stretch film stabilizes the lightweight structure during the shipment. Usually, a stretch wrapping machine applies this stretch film to the pallet. The objective of this study is to support packaging development with a method that predicts the result of the wrapping process, based on the mechanical characterization of the stretch film. This result is not only defined by the amount of stretch film, its spatial distribution on the pallet and its internal stresses that result in a containment force. More accurate, this contribution also considers the influence of the deformation history of the stretch film during the wrapping process. By focusing on similarities of stretch wrappers rather than on differences, the influence of generalized process parameters on stretch film mechanics and thereby on pallet stability can be determined experimentally. For a practical use, the predictive method is accumulated in an analytic model of the wrapping process that can be verified experimentally. This paves the way for experimental and numerical approaches regarding the optimization of pallet stability.

    Innovations in optical microscopy have opened new windows onto scientific research, industrial quality control, and medical practice over the last few decades. One of such innovations is optofluidic time-stretch quantitative phase microscopy - an emerging method for high-throughput quantitative phase imaging that builds on the interference between temporally stretched signal and reference pulses by using dispersive properties of light in both spatial and temporal domains in an interferometric configuration on a microfluidic platform. It achieves the continuous acquisition of both intensity and phase images with a high throughput of more than 10,000 particles or cells per second by overcoming speed limitations that exist in conventional quantitative phase imaging methods. Applications enabled by such capabilities are versatile and include characterization of cancer cells and microalgal cultures. In this paper, we review the principles and applications of optofluidic time-stretch quantitative phase microscopy and discuss its future perspective. Copyright © 2017 Elsevier Inc.

    The rise of stretching tectonics is established on the basis of recent structural geology theory, the establishment of metamorphic nucleus complex structural model on one hand plays an important promoting art to the development of stretching structure, on the other hand, it needs constant supplement and perfection in practice. Metamorphic nucleus complex is the carrier of comparatively deep geological information in vertical section of the crust and has wide distribution in the era of south China. Evidently, it can be taken as the 'key' to understanding the deep and studying the basement, Strengthening the study will play the important promoting role to the deep prospecting. The study of stretching tectonics is not only limited within the range of structure and metamorphism, but combine with the studies of sedimentation, magmatism, metamorphism and mineralization, thus form a new field of tectonic geology of self-developing system

    A simple one-dimensional lattice model is suggested to describe the experimentally observed plateau in force-stretching diagrams for some macromolecules. This chain model involves the nearest-neighbor interaction of a Morse-like potential (required to have a saturation branch) and a harmonic second......-neighbor coupling. Under an external stretching applied to the chain ends, the intersite Morse-like potential results in the appearance of a double-well potential within each chain monomer, whereas the interaction between the second neighbors provides a homogeneous bistable (degenerate) ground state, at least...... stretched bonds with a double-well potential. This case allows us to explain the existence of a plateau in the force-extension diagram for DNA and α-helix protein. Finally, the soliton dynamics are studied in detail....

    Flow cytometry is an indispensable method for valuable applications in numerous fields such as immunology, pathology, pharmacology, molecular biology, and marine biology. Optofluidic time-stretch microscopy is superior to conventional flow cytometry methods for its capability to acquire high-quality images of single cells at a high-throughput exceeding 10,000 cells per second. This makes it possible to extract copious information from cellular images for accurate cell detection and analysis with the assistance of machine learning. Optofluidic time-stretch microscopy has proven its effectivity in various applications, including microalga-based biofuel production, evaluation of thrombotic disorders, as well as drug screening and discovery. In this review, we discuss the principles and recent advances of optofluidic time-stretch microscopy.

Besides the fractal dimension of the foam, we have observed the logistic growth for the soap film length. The stretching and folding mechanism is present during the foam formation, and this mechanism is observed even after the foam has reached its respective maximum fractal dimension. Observing the motion of bubbles inside the foam, large bubbles present power spectrum associated with random walk motion in both directions, while the small bubbles are scattered like balls in a Galton board

Besides the fractal dimension of the foam, we have observed the logistic growth for the soap film length. The stretching and folding mechanism is present during the foam formation, and this mechanism is observed even after the foam has reached its respective maximum fractal dimension. Observing the motion of bubbles inside the foam, large bubbles present power spectrum associated with random walk motion in both directions, while the small bubbles are scattered like balls in a Galton board.

  11. The law of international organisations

    CERN Document Server

    White, Nigel D

    2017-01-01

    This book provides a concise account of the principles and norms of international law applicable to the main-type of international organisation - the inter-governmental organisation (IGO). That law consists of principles and rules found in the founding documents of IGOs along with applicable principles and rules of international law. The book also identifies and analyses the law produced by IGOs, applied by them and, occasionally, enforced by them. There is a concentration upon the United Nations, as the paradigmatic IGO, not only upon the UN organisation headquartered in New York, but on other IGOs in the UN system (the specialised agencies such as the World Health Organisation).

Even though we assume in this article that schools have got some specificities in relation to other organizations, we also recognize that the studies in the education field cannot remain immune to the contributions of other areas. Due to this reason we refer here to the model of Management by Values as a proposal that by breaking away from the more technical-instrumental branches of traditional theories of management, could contribute to a shared reflection with the leadership of educational organisations, specially taking into account the conceptualisation of leadership as a dialogue on values.

    We present the first video-EEG documentation, with ECG and EMG features, of stretch syncope of adolescence in a young, healthy 16-year-old boy. Stretch syncope of adolescence is a rarely reported, benign cause of fainting in young patients, which can be confused with epileptic seizures. In our patient, syncopes were self-induced to avoid school. Dynamic transcranial Doppler showed evidence of blood flow decrease in both posterior cerebral arteries mimicking effects of a Valsalva manoeuvre. Dynamic angiogram of the vertebral arteries was normal. Hypotheses concerning the physiopathology are discussed. [Published with video sequences].

    Blood clots, whose main structural component is a mesh of microscopic fibrin fibers, experience mechanical strain from blood flow, clot retraction and interactions with platelets and other cells. We developed a transparent, striated and highly stretchable substrate made from fugitive glue (a styrenic block copolymer) to investigate how mechanical strain affects lysis of single, suspended fibrin fibers. In this suspended fiber assay, lysis manifested itself by fiber elongation, thickening (disassembly), fraying and collapse. Stretching single fibrin fibers significantly hampered their lysis. This effect was seen in uncrosslinked and crosslinked fibers. Crosslinking (without stretching) also hampered single fiber lysis. Our data suggest that strain is a novel mechanosensitive factor that regulates blood clot dissolution (fibrinolysis) at the single fiber level. At the molecular level of single fibrin molecules, strain may distort, or hinder access to, plasmin cleavage sites and thereby hamper lysis. Fibrin fibers are the major structural component of a blood clot. We developed a highly stretchable substrate made from fugitive glue and a suspended fibrin fiber lysis assay to investigate the effect of stretching on single fibrin fibers lysis. The key findings from our experiments are: 1) Fibers thicken and elongate upon lysis; 2) stretching strongly reduces lysis; 3) this effect is more pronounced for uncrosslinked fibers; and 4) stretching fibers has a similar effect on reducing lysis as crosslinking fibers. At the molecular level, strain may distort plasmin cleavage sites, or restrict access to those sites. Our results suggest that strain may be a novel mechanobiological factor that regulates fibrinolysis. Copyright © 2017 Acta Materialia Inc. Published by Elsevier Ltd. All rights reserved.

    Full Text Available Purpose: The aim of this article is to analyse the theoretical views and results of empirical research concerning the relation between organisational learning (OL and organisational performance (OP. Methodology: The study was carried out through extensive literature research, including relevant literature review from databases such as ProQuest, Elsevier, Emerald and EBSCO (the phrases: “organisational learning”, “learning organisation” and “organisational performance” were searched in the keywords, titles or abstracts. Findings: From a theoretical point of view, the relation between OL and OP is neither obvious nor clear, but the analysis of the empirical studies allows one to assume that OL has an essential impact on OP. However, differences in the strength of the relation were shown and some contradictions related to the presence of the relation between OL and selected (mostly financial performance aspects identified. Furthermore, the article discusses the significant differences and inconsistencies in the methods of measuring OL, measuring OP, selecting contextual factors and adopted methods of data analysis. Implications: Inconsistencies and gaps found in the studies of the relationship between OL and OP made it possible to designate the direction for promising further research. Value: The article presents valuable insight through its in-depth, critical analysis of the organisational learning and organisational outcomes. First and foremost, this indicates that the formula of the previous empirical studies does not allow for the development of precise solutions pertaining to organisational learning management for the benefit of OP improvement.

    2015-06-01

    Full Text Available Background: Flexibility helps with injury prevention, the reduction of soreness following a workout, and a general sense of well-being. There are different stretching techniques and protocols for improvements in calf extensibility and flexibility. The purpose of the study was to investigate the effectiveness of two techniques i.e. CYCLIC and PNF stretching which improves calf flexibility. This study was done to find the effectiveness of calf Cyclic and PNF stretching technique to improve calf flexibility. Methods: 30 subjects with age group 21-22 years were randomly allocated to 2 groups equally. Group 1(n=15 were given CYCLIC and group 2(n=15 were given PNF stretching technique. Plantar flexion was used to measure the calf tightness which was done before and after the treatment. Treatment was given for 7 days and on the 7th day the calf tightness was again measured. Results: The mean difference of the CYCLIC is 4.6 and mean difference of PNF is 4.7 which indicate that CYCLIC and PNF both are effective to improve calf flexibility but PNF is more effective than CYCLIC to improve calf flexibility. Conclusion: The neurophysiological basis of PNF, stating that the excitatory efficient of the neuromuscular spindle or the inhibitory afferent of the Golgi tendon organ (GTO or both are responsible for the effects. During PNF stretch and isometric contraction of stretched agonists for extended period may cause activation of its neuromuscular spindle. The increase in tension created during the isometric contraction of the pre – lengthened agonist contracts concentrically. Both the fascia & the spindle of the agonist adjust to the nearly lengthened position. These impulses travel via causing post synaptic inhibition of the motor neuron to agonist increasing the tension from the GTO. These impulses can override the impulses coming from the neuromuscular spindles arousing the muscle to reflexly resist to the change in length, thus helping in lengthening

    Neck pain is one of the most common and painful musculoskeletal conditions. Point prevalence ranges from 6% to 22% and up to 38% of the elderly population, while lifetime prevalence ranges from 14,2% to 71%. Up till now no randomized study showed the effect between controversy of active and passive stretch on intervertebral movement. The purpose: the current study was to investigate the effect of the passive and active stretch on intervertebral movement in non - specific neck pain. Material and methods: Forty five subjects from both sexes with age range between 18 and 30 years and assigned in three groups, group I (15) received active stretch, ultrasound and TENS. Group II (15) received passive stretch, ultrasound and TENS. Group III (15) received ultrasound and TENS. The radiological assessment was used to measure rotational and translational movement of intervertebral movement before and after treatment. Results: MANOVA test was used for radiological assessment before and after treatment there was significant increase in intervertebral movement in group I as p value =0.0001. Conclusion: active stretch had a effect in increasing the intervertebral movement compared to the passive stretch

    2014-12-01

    Full Text Available This article uses the case of a regional intermediary organisation to investigate organisational memory (OM and its contribution to knowledge management and activities in evaluations. Understanding of, and accessing OM is critical for participatory evaluations. The aim of the article is to reflect on the OM of a non-governmental organisation (NGO and what implicationsthe structural changes in OM over the organisation’s life cycle have for evaluators. It further aims to advocate an awareness of OM and explains how evaluators can access and utilise it more effectively. Evaluators need to have an understanding of OM, and to take more responsibility for disseminating results to enhance it. This case study reflects on a retrospective case example of a regional NGO. The report reflects the development and structure of the life cycle of the organisation. The data collection included in-depth interviews with staff members and other key stakeholders, engagement with beneficiary organisations and donors, and analyses of documents, electronic files and audio-visual material. Since OM survives after the demise of an organisation, and is accessible through directories, it is important for the evaluator to include historical information. Specific implications for evaluators include the ability to access OM through directories and networks of the organisation. As evaluators hold OM of all the organisations they have engaged with, they also have a responsibility to share knowledge. The key findings of this study illustrate the importance of accessing the memory and historical information of the organisation. Understanding OM enhances the in-depth comprehension of the activity, project or programme under investigation, and the collective knowledge generated as a result of it.

    Full Text Available This study explores the empirical link between different dimensions of organizational commitment and turnover intentions on Nigeria paramilitary organisation. A literature review of organizational commitment and employee turnover provides the basis for the research hypotheses. Four research hypotheses were formulated and tested at 95% and 99% confidence level. The study adopted a survey research design. A self-administered questionnaire was used, involving 144 respondents from selected paramilitary organisation in Akure, Nigeria to collect data and testing the existing theory. Data collected were analysed using both descriptive and inferential statistical techniques. In contrary to theory, the study revealed a weak positive relationship between organizational commitment dimensions (affective, continuance and normative and turnover intentions. The relationships are statistically significant expect the one between turnover intention and normative commitment which is statistically insignificant. The study concluded that the commitment of an employee to organisational goals, missions, and values is not enough to predict his/her stay in the organisation. There are other variables apart from organisational commitment that are predictor of employees’ intentions to quit. Thus, organisations should look beyond forces in their internal environment, when considering reduction in employee’s turnover intentions and the actual employee’s turnover.

    Dependence on car use has a number of broad health implications, including contributing to physical inactivity, road traffic injury, air pollution and social severance, as well as entrenching lifestyles that require environmentally unsustainable energy use. Travel plans are interventions that aim to reduce single-occupant car use and increase the use of alternatives such as walking, cycling and public transport, with a variety of behavioural and structural components. This review focuses on organisational travel plans for schools, tertiary institutes and workplaces. These plans are closely aligned in their aims and intervention design, having emerged from a shared theoretical base. To assess the effects of organisational travel plans on health, either directly measured, or through changes in travel mode. We searched the following electronic databases; Transport (1988 to June 2008), MEDLINE (1950 to June 2008), EMBASE (1947 to June 2008), CINAHL (1982 to June 2008), ERIC (1966 to June 2008), PSYCINFO (1806 to June 2008), Sociological Abstracts (1952 to June 2008), BUILD (1989 to 2002), Social Sciences Citation Index (1900 to June 2008), Science Citation Index (1900 to June 2008), Arts & Humanities Index (1975 to June 2008), Cochrane Database of Systematic Reviews (to August 2008), CENTRAL (to August 2008), Cochrane Injuries Group Register (to December 2009), C2-RIPE (to July 2008), C2-SPECTR (to July 2008), ProQuest Dissertations & Theses (1861 to June 2008). We also searched the reference lists of relevant articles, conference proceedings and Internet sources. We did not restrict the search by date, language or publication status. We included randomised controlled trials and controlled before-after studies of travel behaviour change programmes conducted in an organisational setting, where the measured outcome was change in travel mode or health. Both positive and negative health effects were included. Two authors independently assessed eligibility, assessed trial

  9. Spontaneous bending of pre-stretched bilayers.

    We discuss spontaneously bent configurations of pre-stretched bilayer sheets that can be obtained by tuning the pre-stretches in the two layers. The two-dimensional nonlinear plate model we use for this purpose is an adaptation of the one recently obtained for thin sheets of nematic elastomers, by means of a rigorous dimensional reduction argument based on the theory of Gamma-convergence (Agostiniani and DeSimone in Meccanica. doi:10.1007/s11012-017-0630-4, 2017, Math Mech Solids. doi:10.1177/1081286517699991, arXiv:1509.07003, 2017). We argue that pre-stretched bilayer sheets provide us with an interesting model system to study shape programming and morphing of surfaces in other, more complex systems, where spontaneous deformations are induced by swelling due to the absorption of a liquid, phase transformations, thermal or electro-magnetic stimuli. These include bio-mimetic structures inspired by biological systems from both the plant and the animal kingdoms.

  10. Dynamics and structure of stretched flames

    Energy Technology Data Exchange (ETDEWEB)

    Law, C.K. [Princeton Univ., NJ (United States)

    1993-12-01

    This program aims to gain fundamental understanding on the structure, geometry, and dynamics of laminar premixed flames, and relate these understanding to the practical issues of flame extinction and stabilization. The underlying fundamental interest here is the recent recognition that the response of premixed flames can be profoundly affected by flame stretch, as manifested by flow nonuniformity, flame curvature, and flame/flow unsteadiness. As such, many of the existing understanding on the behavior of premixed flames need to be qualitatively revised. The research program consists of three major thrusts: (1) detailed experimental and computational mapping of the structure of aerodynamically-strained planar flames, with emphasis on the effects of heat loss, nonequidiffusion, and finite residence time on the flame thickness, extent of incomplete reaction, and the state of extinction. (2) Analytical study of the geometry and dynamics of stretch-affected wrinkled flame sheets in simple configurations, as exemplified by the Bunsen flame and the spatially-periodic flame, with emphasis on the effects of nonlinear stretch, the phenomena of flame cusping, smoothing, and tip opening, and their implications on the structure and burning rate of turbulent flames. (3) Stabilization and blowoff of two-dimensional inverted premixed and stabilization and determining the criteria governing flame blowoff. The research is synergistically conducted through the use of laser-based diagnostics, computational simulation of the flame structure with detailed chemistry and transport, and mathematical analysis of the flame dynamics.

  12. A typology of organisational cultures.

    Westrum, R

    2004-12-01

    There is wide belief that organisational culture shapes many aspects of performance, including safety. Yet proof of this relationship in a medical context is hard to find. In contrast to human factors, whose contributions are many and notable, culture's impact remains a common-sense, rather than a scientific, concept. The objectives of this paper are to show that organisational culture bears a predictive relationship with safety and that particular kinds of organisational culture improve safety, and to develop a typology predictive of safety performance. Because information flow is both influential and also indicative of other aspects of culture, it can be used to predict how organisations or parts of them will behave when signs of trouble arise. From case studies and some systematic research it appears that information culture is indeed associated with error reporting and with performance, including safety. Yet this relationship between culture and safety requires more exploration before the connection can be considered definitive.

    Hopkin, Paul

    There have been many high-profile incidents in recent times that have affected both individual organisations and large parts of society. In response to these disasters and their consequences, there has been increasing focus on the concept of 'resilience'. Airmic worked with Cranfield School of Management to investigate the features of resilient organisations and whether common characteristics could be identified. The research summarised in this paper discovered five principles that increase an organisation's level of resilence. The paper also reports on the actions taken by organisations to embed these resilience principles into four main business enablers. These business enablers in combination represent the business model of the organisation. The overall conclusion of the research was that, in order to achieve a state of enhanced resilience, organisations need to be aware of risks and threats they face and then combine the actions required to be 'risk compliant' with the ability to be 'risk responsive'.

    This study aimed to compare the effect of different static stretching durations followed by dynamic stretching on repeated sprint ability (RSA) and change of direction (COD). Twenty-five participants performed the RSA and COD tests in a randomized order. After a 5 min aerobic warm up, participants performed one of the three static stretching protocols of 30 s, 60 s or 90 s total duration (3 stretches x 10 s, 20 s or 30 s). Three dynamic stretching exercises of 30 s duration were then performed (90 s total). Sit-and-reach flexibility tests were conducted before the aerobic warm up, after the combined static and dynamic stretching, and post- RSA/COD test. The duration of static stretching had a positive effect on flexibility with 36.3% and 85.6% greater sit-and-reach scores with the 60 s and 90 s static stretching conditions respectively than with the 30 s condition (p ≤ 0.001). However there were no significant differences in RSA and COD performance between the 3 stretching conditions. The lack of change in RSA and COD might be attributed to a counterbalancing of static and dynamic stretching effects. Furthermore, the short duration (≤ 90 s) static stretching may not have provided sufficient stimulus to elicit performance impairments.

  18. To Stretch and Search for Better Ways

    There's a lot to do to get each issue of this Journal ready for publication, and there's a lot that can go awry during that process. We the editorial staff do our utmost to make certain that each issue is the best it can possibly be, but, of necessity, a lot of our effort is focused on solving problems, correcting errors, and avoiding pitfalls. It is not surprising that we sometimes lose sight of the bigger picture--all of the things that came out as well as or better than we hoped they would. Therefore it gives us great pleasure when a reader applauds (and thereby rewards) our efforts. One such communication inspired this editorial. I have appreciated the extra effort put forward by the staff to make the Journal really come alive. The high quality of the Journal serves as an incentive to chemical educators to stretch and search for better ways to inspire our students. I fervently hope that we do encourage you "to stretch and search for better ways", not only to inspire students but in everything you do. Stretching and searching for better ways is what life, science, chemistry, and teaching are all about, and it is a wonderfully stimulating and exciting way to approach anything and everything. Sometimes, though, one's ability to stretch is akin to that of a rubber band exposed too long to sunlight. Change becomes a threat or a burden instead of an opportunity. This often happens in one area but not others, as in the case of someone doing original research but whose lecture notes are yellow with age, or someone who experiments with new teaching approaches but neglects the latest chemical discoveries. Whatever its manifestation, failure to stretch and search for better ways is a great loss, both for the individual directly involved and for others. Fortunately there are many who continually stretch and search, often in conjunction with JCE. For example, some time ago the Chair of the Board of Publication, Jerry Bell, challenged Journal readers to become Journal

  19. Stretched horizons, quasiparticles, and quasinormal modes

    We propose that stretched horizons can be described in terms of a gas of noninteracting quasiparticles. The quasiparticles are unstable, with a lifetime set by the imaginary part of the lowest quasinormal mode frequency. If the horizon arises from an AdS-CFT style duality the quasiparticles are also the effective low-energy degrees of freedom of the finite-temperature CFT. We analyze a large class of models including Schwarzschild black holes, nonextremal Dp-branes, the rotating BTZ black hole and de Sitter space, and we comment on degenerate horizons. The quasiparticle description makes manifest the relationship between entropy and area

    2017-01-01

    This authored monograph provides a detailed discussion of the boundary layer flow due to a moving plate. The topical focus lies on the 2- and 3-dimensional case, considering axially symmetric and unsteady flows. The author derives a criterion for the self-similar and non-similar flow, and the turbulent flow due to a stretching or shrinking sheet is also discussed. The target audience primarily comprises research experts in the field of boundary layer flow, but the book will also be beneficial for graduate students.

  1. Phylogenetic Origins of Brain Organisers

    Directory of Open Access Journals (Sweden)

    Ellen Robertshaw

    2012-01-01

    Full Text Available The regionalisation of the nervous system begins early in embryogenesis, concomitant with the establishment of the anteroposterior (AP and dorsoventral (DV body axes. The molecular mechanisms that drive axis induction appear to be conserved throughout the animal kingdom and may be phylogenetically older than the emergence of bilateral symmetry. As a result of this process, groups of patterning genes that are equally well conserved are expressed at specific AP and DV coordinates of the embryo. In the emerging nervous system of vertebrate embryos, this initial pattern is refined by local signalling centres, secondary organisers, that regulate patterning, proliferation, and axonal pathfinding in adjacent neuroepithelium. The main secondary organisers for the AP neuraxis are the midbrain-hindbrain boundary, zona limitans intrathalamica, and anterior neural ridge and for the DV neuraxis the notochord, floor plate, and roof plate. A search for homologous secondary organisers in nonvertebrate lineages has led to controversy over their phylogenetic origins. Based on a recent study in hemichordates, it has been suggested that the AP secondary organisers evolved at the base of the deuterostome superphylum, earlier than previously thought. According to this view, the lack of signalling centres in some deuterostome lineages is likely to reflect a secondary loss due to adaptive processes. We propose that the relative evolutionary flexibility of secondary organisers has contributed to a broader morphological complexity of nervous systems in different clades.

    Purpose - The purpose of this paper is to fill an apparent gap in the literature addressing issues of leadership and change - the development and activities of constructing and leading sports sciences and medicine professions, and similarly, the construction and leadership of multidisciplinary/inter-disciplinary organisations that practice sports sciences and medicine. Design/methodology/approach - This study incorporated explorations through conducting both interviews and survey questionnaires with members of Sports Medicine Australia (SMA). The interviews (qualitative) were semi-structured and asked questions addressing what changed, why change and how change was implemented. Findings - The health sciences and medicine professions moving to specialised sports sciences and medicine disciplines and SMA, evolved through forces driving the need for change (legitimacy, resource dependency, positioning and core competencies). Practical implications - The knowledge developed from understanding activities of change that traditional professions conducted to become specialised Disciplines and parallel changes in a single Discipline organisation evolving to an umbrella organisation (SMA), comprised a membership of specialised Disciplines, can act as a catalyst for inquiry by other professional and organisational groups. Originality/value - The findings of this study contributes to the literature investigating change in professional and organisations fields. More specifically, this study promotes inquiry into leadership practices of sports sciences and medicine, as contributors to the field of health services.

    Kwong Wah Hospital was founded by the charity organisation Tung Wah Group of Hospitals some 88 years ago, with management transfer to the Hong Kong Hospital Authority in 1991. Capitalizing both from the traditional caring culture of its founder, as well as opportunities in the new management environment, the hospital has scored remarkable successes in service quality, community partnership, organisational effectiveness, and staff development. Underpinning these transformations were Structure, Process, People, and Culture strategies. The learning imperative is heavily mandated or the success of each of these strands of development. Indeed, the embodiment of a learning organisation culture provides the impetus in sustaining the change momentum, towards achieving the Vision of becoming a 'Most Preferred Hospital' in Hong Kong.

  6. Twist-stretch profiles of DNA chains

    Zoli, Marco

    2017-06-01

    Helical molecules change their twist number under the effect of a mechanical load. We study the twist-stretch relation for a set of short DNA molecules modeled by a mesoscopic Hamiltonian. Finite temperature path integral techniques are applied to generate a large ensemble of possible configurations for the base pairs of the sequence. The model also accounts for the bending and twisting fluctuations between adjacent base pairs along the molecules stack. Simulating a broad range of twisting conformation, we compute the helix structural parameters by averaging over the ensemble of base pairs configurations. The method selects, for any applied force, the average twist angle which minimizes the molecule’s free energy. It is found that the chains generally over-twist under an applied stretching and the over-twisting is physically associated to the contraction of the average helix diameter, i.e. to the damping of the base pair fluctuations. Instead, assuming that the maximum amplitude of the bending fluctuations may decrease against the external load, the DNA molecule first over-twists for weak applied forces and then untwists above a characteristic force value. Our results are discussed in relation to available experimental information albeit for kilo-base long molecules.

    A universal feature of glasses is the stretched exponential relaxation, f (t) = exp[ - t / τ ] β . The model of diffusion of excitations to randomly distributed traps in a glass by Phillips1 yields the stretched exponent β = d[d +2] where d, the effective dimensionality. We have measured the enthalpy of relaxation ΔHnr (tw) at Tg of Se glass in modulated DSC experiments as glasses age at 300K and find β = 0.43(2) for tw in the 0

    2014-03-01

    Sensing motion of the human body is a difficult task. From an engineers' perspective people are soft highly mobile objects that move in and out of complex environments. As well as the technical challenge of sensing, concepts such as comfort, social intrusion, usability, and aesthetics are paramount in determining whether someone will adopt a sensing solution or not. At the same time the demands for human body motion sensing are growing fast. Athletes want feedback on posture and technique, consumers need new ways to interact with augmented reality devices, and healthcare providers wish to track recovery of a patient. Dielectric elastomer stretch sensors are ideal for bridging this gap. They are soft, flexible, and precise. They are low power, lightweight, and can be easily mounted on the body or embedded into clothing. From a commercialisation point of view stretch sensing is easier than actuation or generation - such sensors can be low voltage and integrated with conventional microelectronics. This paper takes a birds-eye view of the use of these sensors to measure human body motion. A holistic description of sensor operation and guidelines for sensor design will be presented to help technologists and developers in the space.

  9. Curved Piezoelectric Actuators for Stretching Optical Fibers

    Science.gov (United States)

    Allison, Sidney G.; Shams, Qamar A.; Fox, Robert L.

    2008-01-01

    Assemblies containing curved piezoceramic fiber composite actuators have been invented as means of stretching optical fibers by amounts that depend on applied drive voltages. Piezoceramic fiber composite actuators are conventionally manufactured as sheets or ribbons that are flat and flexible, but can be made curved to obtain load-carrying ability and displacement greater than those obtainable from the flat versions. In the primary embodiment of this invention, piezoceramic fibers are oriented parallel to the direction of longitudinal displacement of the actuators so that application of drive voltage causes the actuator to flatten, producing maximum motion. Actuator motion can be transmitted to the optical fiber by use of hinges and clamp blocks. In the original application of this invention, the optical fiber contains a Bragg grating and the purpose of the controlled stretching of the fiber is to tune the grating as part of a small, lightweight, mode-hop-free, rapidly tunable laser for demodulating strain in Bragg-grating strain-measurement optical fibers attached to structures. The invention could also be used to apply controllable tensile force or displacement to an object other than an optical fiber.

  10. The effect of organisational context on organisational development (OD interventions

    2012-05-01

    Research purpose: This article examines national and international OD practices. It assesses the effect of diverse cultures and cultural values for determining the effectiveness of OD interventions. Motivation for the study: Most organisational change and development programmes fail and only a few result in increased competitiveness, improvements and profitability. This emphasises the need for change interventions to give sufficient attention to leadership, cultures, managing change and adopting context-based OD interventions. Research design, approach and method: This article is a literature review of the current trends and research in the area of OD interventions. It synthesises the influence that cultures and cultural orientations have on determining which OD intervention strategies organisations should adopt in different cultures. Main findings: The analysis emphasises how important it is to achieve congruence between the OD interventions organisations select and their local cultures. Practical/managerial implications: It is important to note the evolving nature of the political and economic climates that influence national cultures and that they emphasise that interventions that reflect OD values, which are tailor-made and shaped to the needs of local cultures, are necessary. Contribution/value-add: This study links various OD interventions to Hofstede’s dimensions for differentiating national cultures. It provides guidelines for aligning the practices and techniques of OD to the values and cultures of the organisations and societies in which they are to be implemented.

    Implementing the World Health Organisation (WHO) Framework Convention on Tobacco Control (FCTC) relies heavily on enforcement. Little is known of the way different enforcement agencies operate, prioritise or network. A questionnaire was sent to representatives of the International Federation of Environmental Health (IFEH) in 36 countries. Tobacco control was given low priority. Almost two thirds did not have any tobacco control policy. A third reported their organisation had worked with other agencies on tobacco control. Obstacles to addressing tobacco control included a lack of resources (61%) and absence of a coherent strategy (39%).

    2014-05-01

    To examine the association between perceived organisational values and organisational commitment among Israeli nurses in relation to their ethno-cultural background. Differences and the discrepancy between individuals' organisational values and those of their organisational culture are a potential source of adjustment difficulties. Organisational values are considered to be the bond of the individual to their organisation. In multicultural societies, such as Israel, the differences in perception of organisational values and organisational commitment may be reflected within workgroups. Data were collected using a questionnaire among 106 hospital nurses. About 59.8% of the sample were Israeli-born. A positive correlation was found between organisational values and organisational commitment. Significant differences were found in organisational values and organisational commitment between Israeli-born-, USSR-born- and Ethiopian-born nurses. The socio-demographic profile modified the effect of organisational values on organisational commitment: when the nurse was male, Muslim, religiously orthodox and without academic education, the effect of organisational values on organisational commitment was higher. Findings confirm the role of culture and ethnicity in the perception of organisational values and the level of organisational commitment among nurses. Assessing ethno-cultural differences in organisational values and organisational commitment provides a fuller understanding of nurses' ability to adjust to their work environment and helps nurse managers devise means to increase nurses' commitment. © 2012 John Wiley & Sons Ltd.

    Science.gov (United States)

    Matsudaira, Yoshito

    This paper examines knowledge creation in relation to improvements on the production line in the manufacturing department of Nissan Motor Company and aims to clarify embodied knowledge observed in the actions of organisational members who enable knowledge creation will be clarified. For that purpose, this study adopts an approach that adds a first, second, and third-person's viewpoint to the theory of knowledge creation. Embodied knowledge, observed in the actions of organisational members who enable knowledge creation, is the continued practice of 'ethos' (in Greek) founded in Nissan Production Way as an ethical basis. Ethos is knowledge (intangible) assets for knowledge creating companies. Substantiated analysis classifies ethos into three categories: the individual, team and organisation. This indicates the precise actions of the organisational members in each category during the knowledge creation process. This research will be successful in its role of showing the indispensability of ethos - the new concept of knowledge assets, which enables knowledge creation -for future knowledge-based management in the knowledge society.

    The success of organisational change is often thwarted by leaders' failure to consider staff feelings. Managers must communicate a clear vision for the future, even though they may be facing great professional uncertainty themselves. It is important to deal with post-merger issues such as helping staff to new roles and 'unlearning' old ways.

Aerospace performed preliminary analysis: a) Potential savings; b) Cost of implementation; c) Performance or other impact/penalties; d) Roadblocks; e) Unintended consequences; f) Bottom line. Significant work ahead for a "Stretch Goal"to become a good, documented requirement: 1) As a group, the relative "value" of goals are uneven; 2) Focused analysis on each goal is required: a) Need to ensure that a new requirement produces the desired consequence; b) It is not certain that some goals will not create problems elsewhere. 3) Individual implementation path needs to be studied: a) Best place to insert requirement (what level, which document); b) Appropriate wording for the requirement. Many goals reflect "best practices" based on lessons learned and may have value beyond near-term CxP requirements process.

  2. LABOR GYMNASTICS: STRETCHING EXERCISE X FLEXIONAMENT

    Full Text Available Nowadays, there are many opportunities for the society to live a healthful and long life. At the same time, never people was so sedentary and without harmony. Without a healthy body and with “an occupied mind” the human loses exactly what more it needs: the disposal to produce, to coexist and to live a good life. In this context, the present research aimed to revise some terms related to labor gymnastics, which is focused in the prevention of risks related to hours of working and in the reduction of muscular tension levels that may be originated during a day of work. Thus, the present study will make a differentiation between the use of stretching and flexionament during labor gymnastic sessions.

    to measure both linear and nonlinear dynamics on a single apparatus. With a software modification to the FSR motor control, we show that linear viscoelasticity can be measured via small amplitude squeeze flow (SASF). Squeeze flow is a combination of both shear and extensional flow applied by axially......Traditionally, linear viscoelasticity is measured using small amplitude oscillatory shear flow. Due to experimental difficulties, shear flows are predominately confined to the linear and mildly nonlinear regime. On the other hand, extensional flows have proven more practical in measuring...... viscoelasticity well into the nonlinear regime. Therefore at present, complete rheological characterization of a material requires two apparatuses: a shear and an extensional rheometer. This work is focused on developing a linear viscoelastic protocol for the filament stretching rheometer (FSR) in order...

    Thin glass sheets are used in smartphone, battery and semiconductor technology, and may be manufactured by producing a relatively thick glass slab and subsequently redrawing it to a required thickness. The resulting sheets commonly possess undesired centerline ripples and thick edges. We present a mathematical model in which a viscous sheet undergoes redraw in the direction of gravity, and show that, in a sufficiently strong gravitational field, buckling is driven by compression in a region near the bottom of the sheet, and limited by viscous resistance to stretching of the sheet. We use asymptotic analysis in the thin-sheet, low-Reynolds-number limit to determine the centerline profile and growth rate of such a viscous sheet.

  5. Loads applied to fixations for chain stretching

    1985-06-01

    The chains of scraper chain conveyors must be pre-stretched during standstill in order to compensate the elongations occurring during operation. They require frequent retensiening in order to meet the varying operational requirements. During tensioning, the chains are fixed in a point in the top run by means of fixation elements. The authors present a method for calculating the retaining force needed in the fixations. There are three different initial conditions of the chain before trensioning: Tensionsfree chain, pretensioned chain (stressed chain), slack chain. In all three cases, it is important to find out whether or nor the tensioning drive reaches full speed. The method of calculation is illustrated by the example of a scraper chain conveyor; it enables the establishment of rules for tensioning without damaging the chain and is a good basis for the dimensioning of new types of fixation elements.

  6. Aerothermodynamic properties of stretched flames in enclosures

    Science.gov (United States)

    Rotman, D. A.; Oppenheim, A. K.

    Flames are stretched by being pulled along their frontal surface by the flow field in which they reside. Their trajectories tend to approach particle paths, acquiring eventually the role of contact boundaries, -interfaces between the burnt and unburnt medium that may broaden solely as a consequence of diffusion. Fundamental properties of flow fields governing such flames are determined here on the basis of the zero Mach number model, providng a rational method of approach to the computational analysis of combustion fields in enclosures where, besides the aerodynamic properties flow, the thermodynamic process of compression must be taken into account. To illustrate its application, the method is used to reveal the mechanism of formation of a tulip-shape flame in a rectangular enclosure under nonturbulent flow conditions.

  7. Correlation between structure and conductivity in stretched Nafion

    2008-03-01

    We have used coarse-grained simulation methods to investigate the effect of stretching-induced structure orientation on the proton conductivity of Nafion-like polyelectrolyte membranes. Recent experimental data on the morphology of ionomers describe Nafion as an aggregation of polymeric backbone chains forming elongated objects embedded in a continuous ionic medium. Uniaxial stretching of a recast Nafion film causes a preferential orientation of these objects in the direction of stretching. Our simulations of humid Nafion show that this has a strong effect on the proton conductivity, which is enhanced along the stretching direction, while the conductivity perpendicular to the stretched polymer backbone is strongly reduced. Stretching also causes the perfluorinated side chains to orient perpendicular to the stretching axis. The sulphonate multiplets shrink in diameter as the stretching is increased and show a spatially periodic ordering in their distribution. This in turn affects the distribution of contained water at low water contents. The water forms a continuous network with narrow bridges between small water clusters absorbed in head-group multiplets. We find the morphological changes in the stretched Nafion to be retained upon removal of the uniaxial stress.

    Good management and the best possible direction of affairs are concepts which have to be striven for constantly and unremittingly within a business. The strategy of organisation development provides a framework for our times to achieve these aims. Seven criteria are discussed, which provide ways and means of managing a mine with as little red tape as possible and of constantly and flexibly adapting to human, technical and ambient changes. Much is demanded from everyone in the organisation, and everyone demands much from himself. The employees evolve into ''men of enterprise within the enterprise'' and are motivated and keen. Their qualifications and competence increase in the measure in which their projects to improve the work situation in the widest sense are successful.

    The process of reaction to system failures and security attacks is strongly influenced by its infrastructural, procedural and organisational settings. Analysis of reaction procedures and practices from different domains (Air Traffic Management, Response to Computer Security Incident, Response to emergencies, recovery in Chemical Process Industry) highlight three key requirements for this activity: smooth collaboration and coordination among responders, accurate monitoring and management of resources and ability to adapt pre-established reaction plans to the actual context. The SERENITY Reaction Mechanisms (SRM) is the subsystem of the SERENITY Run-time Framework aimed to provide SERENITY aware AmI settings (i.e. socio-technical systems with highly distributed dynamic services) with functionalities to implement applications specific reaction strategies. The SRM uses SERENITY Organisational S&D Patterns as run-time models to drive these three key functionalities.

    2015-01-01

    Organising pneumonia is one of the responses of the lung to injury and can mimic bacterial pneumonia but importantly it does not respond to antibiotic therapy. We present the case of a 67-year-old male who was diagnosed with organising pneumonia secondary to dronedarone. Drug reactions are a common cause and early identification of the culprit is mandatory to prevent further morbidity and ensure a favourable outcome. On chest radiography there may be fleeting peripheral consolidation, while computed tomography can show a range of stereotyped patterns including perilobular consolidation. Bronchoscopic biopsy may not always be possible but response to steroids is often rapid following removal of the culprit drug. Dronedarone should be included in the list of possible drugs and the Pneumotox database remains a useful resource for the clinician when acute drug-related pneumotoxicity is suspected.

  19. Feminine leadership and organisational culture

    Full Text Available People in general, leaders especially, are influenced by the organisational culture and the other way around. Organisational culture represents a determining factor regarding the display of leadership, since these two processes create each other, adding value and consistency to one another. Moreover, organisational culture can be created and developed in a fluctuant business environment, in which the external factors influence its progress. The development of society has incessantly been emphasized by the relationship between the sexes, by their individual evolution, but also by the interdependency between them. Although there is increasingly more talk about gender equality, in many countries, the social as well as economical chances and opportunities are not equal for women and men. Gradually, women have been through a series of changes related to education, rights and obligations. However, the number of women leaders has always been much lower than the number of men leaders. The personality traits of leaders significantly influence the leadership style and the way in which they are perceived by their subordinates, all this having a major impact on the overall performances of the organisation. In this manner, depending on the gender (masculine/feminine, we can state that one could observe certain personality traits that are characteristic to women and others specific to men, leaving their mark on the leadership method and on the leadership style adopted of each of them. Considering the fact that, in the current turbulent economic environment, certain qualities such as flexibility, intuition, development of communication networks and motivating the employees represent values that are considered to be “feminine”, one can assert that, in this case, gender is an opportunity. However, if we should take into consideration the impact of culture, of certain mentalities and misconceptions that are still present, regarding the woman’s standing in

  3. Communication in third sector organisations

    Directory of Open Access Journals (Sweden)

    Patricia Durán-Bravo, M.A.

    2010-01-01

    Full Text Available Third sector organisations favour the social development due to their capacity to produce human and social capital in society (Putman, 2001. In order to achieve social welfare third sector organisations need to produce a positive change in the relations among individuals, groups and institutions in a society. The expectations about the third sector organisations’ transparency and capacity to tackle social problems are increasing worldwide. In Mexico, this problematic is more complex because there is a low level of professionalism, transparency, accountability and participation culture in the organized civil society (ITAM, 2010. The development of the organized civil society in Mexico will depend to a great extent on its capacity to communicate its values to society and achieve a cultural and social change. Therefore, the third sector organisations must adopt strategic initiatives to reinforce their credibility and reputation, because the public and private donors are increasingly more demanding in their criteria to grant resources to social projects; and because the Mexican society has a low participation level and faces increasingly more complex social problems.

  4. The stretch reflex and the contributions of C David Marsden

    Directory of Open Access Journals (Sweden)

    Kalyan B Bhattacharyya

    2017-01-01

    Full Text Available The stretch reflex or myotatic reflex refers to the contraction of a muscle in response to its passive stretching by increasing its contractility as long as the stretch is within physiological limits. For ages, it was thought that the stretch reflex was of short latency and it was synonymous with the tendon reflex, subserving the same spinal reflex arc. However, disparities in the status of the two reflexes in certain clinical situations led Marsden and his collaborators to carry out a series of experiments that helped to establish that the two reflexes had different pathways. That the two reflexes are dissociated has been proved by the fact that the stretch reflex and the tendon reflex, elicited by stimulation of the same muscle, have different latencies, that of the stretch reflex being considerably longer. They hypothesized that the stretch reflex had a transcortical course before it reached the spinal motor neurons for final firing. Additionally, the phenomenon of stimulus-sensitive cortical myoclonus lent further evidence to the presence of the transcortical loop where the EEG correlate preceded the EMG discharge. This concept has been worked out by later neurologists in great detail , and the general consensus is that indeed, the stretch reflex is endowed with a conspicuous transcortical component.

    Polymer thin films have irregular transient current characteristics under constant voltage. In hydrophilic and hydrophobic polymers, the irregularity is also known to depend on the humidity absorbed by the polymer sample. Different stretched exponential models are studied and it is shown that the absorption of humidity as a function of time can be adequately modelled by a class of these stretched exponential absorption models.

  7. Bruxism: Is There an Indication for Muscle-Stretching Exercises?

    Science.gov (United States)

    Gouw, Simone; de Wijer, Anton; Creugers, Nico Hj; Kalaykova, Stanimira I

    Bruxism is a common phenomenon involving repetitive activation of the masticatory muscles. Muscle-stretching exercises are a recommended part of several international guidelines for musculoskeletal disorders and may be effective in management of the jaw muscle activity that gives rise to bruxism. However, most studies of muscle-stretching exercises have mainly focused on their influence on performance (eg, range of motion, coordination, and muscle strength) of the limb or trunk muscles of healthy individuals or individuals with sports-related injuries. Very few have investigated stretching of the human masticatory muscles and none muscle-stretching exercises in the management of (sleep) bruxism. This article reviews the literature on muscle-stretching exercises and their potential role in the management of sleep bruxism or its consequences in the musculoskeletal system.

Eleven young male subjects with strength training experience, performed 3 tests with a 48h interval between them, randomly selected, where each one subject carried out all procedures: a hand grip without stretching; b hand grip preceded by static stretching of wrist flexors muscles; c hand grip preceded by PNF stretching of wrist flexors muscles. The Shapiro-Wilk test verified the normality of data, and a one-way ANOVA with repeated measures, followed by Tukey’s post hoc test, evaluated the differences between the groups. The significance was set at p 0.05. In conclusion, both stretching methods had caused negative effects on isometric strength, reducing its levels.

    Full Text Available Abstract Background Among youth, participation in extracurricular physical activities at school and organised physical activities in the community is associated with higher physical activity levels. The objective was to determine if participation in organised physical activities during early adolescence protects against declines in physical activity levels during adolescence. Methods Every 3 months for 5 years, students initially in grade 7 (aged 12–13 years completed a 7-day physical activity recall and provided data on the number and type of (extracurricular physical activities organised at school and in the community in which they took part. To study rates of decline in physical activity, only adolescents who reported an average of ≥5 moderate-vigorous physical activity sessions per week in grade 7 (n = 1028 were retained for analyses. They were categorised as to whether or not they were involved in organised physical activities in grade 7. We used generalized estimating equation Poisson regression to compare the rate of decline in number of moderate-vigorous physical activity sessions per week during adolescence between initially physically active students who participated in organised physical activity in grade 7 and those who did not. Results In grade 7, about 87% of physically active adolescents reported taking part in at least one organised physical activity. Compared to active adolescents not involved in organised physical activities, baseline involvement in physical activity was 42% (95% CI 26–59% higher among those involved in organised physical activity (mean number of moderate-vigorous physical activity sessions per week = 14.6 ± 13.1 vs 10.4 ± 9.0. Physical activity declined by 8% per year in both groups. Results were similar in analyses that examined the effect of school or community-based physical activities separately.

    Directory of Open Access Journals (Sweden)

    Criscione John C

    2008-01-01

    Full Text Available Abstract Background Much of the experimental work in soft tissue mechanics has been focused on fitting approximate relations for specific tissue types from aggregate data on multiple samples of the tissue. Such relations are needed for modeling applications and have reasonable predictability – especially given the natural variance in specimens. There is, however, much theoretical and experimental work to be done in determining constitutive behaviors for particular specimens and tissues. In so doing, it may be possible to exploit the natural variation in tissue ultrastructure – so to relate ultrastructure composition to tissue behavior. Thus, this study focuses on an experimental method for determining constitutive behaviors and illustrates the method with analysis of a porcine pulmonary artery strip. The method characterizes the elastic part of the response (implicitly in terms of stretch and the inelastic part in terms of short term stretch history (i.e., stretch-rate Ht2, longer term stretch history Ht1, and time since the start of testing T. Methods A uniaxial testing protocol with a random stretch and random stretch-rate was developed. The average stress at a particular stretch was chosen as the hyperelastic stress response, and deviation from the mean at this particular stretch is chosen as the inelastic deviation. Multivariable Linear Regression Analysis (MLRA was utilized to verify if Ht2, Ht1, and T are important factors for characterizing the inelastic deviation. For acquiring Ht2 and Ht1, an integral function type of stretch history was employed with time constants chosen from the relaxation spectrum of an identical size strip from the same tissue with the same orientation. Finally, statistical models that characterize the inelasticity were developed at various, nominal values of stretch, and their predictive capability was examined. Results Inelastic deviation from hyperelasticity was high (31% for low stretch and declined

    Using magnetic micromanipulation techniques [Strick 96]( uc(T.R.) Strick, J.-F. Allemand, D. Bensimon, A. Bensimon) and uc(V.) Croquette, "The elasticity of a single supercoiled DNA molecule", Science, 271, 1835 (1996)., we have studied the mechanical properties (force versus extension) of single DNA molecules under a wide range of torsional stresses (supercoiling). We show that unwinding the DNA double helix leads to a phase separation between regular B-DNA and denaturation bubbles. The fraction of denatured molecule increases linearly with the degree of unwinding, beginning at a value of 1% unwinding. We have confirmed this denatured state by hybridization of homologous single-stranded DNA probes and by a chemical attack of the exposed bases. Surprisingly, when we overwind the molecule, the elasticity curves we obtain may also be interpreted by the coexistence of two phases, B-DNA and a new phase which we note P-DNA. The fraction of this new phase increases smoothly with overwinding, beginning at 3 % and continuing up to 300 %. Our results indicate that this new phase is four times more twisted that the standard B-DNA and is 1.75 times longer. Although the structure of this phase is not yet known, such a high twisting can only be attained if the sugar-phosphate backbones of the two strands are twisted closely while the bases are expelled outside of the molecule's core, in a structure reminiscent of the one proposed by Pauling. Indeed we have shown that this new phase is sensitive to chemical attack whereas the B-DNA is not. This new phase begins to appear on a molecule overwound by 3 % and stretched by a force of 5 pN, conditions typically encountered in vivo during gene transcription. This new phase may thus play a biological role (for more details).

    Mechanical cues modulate fibroblast tractional forces and remodeling of extracellular matrix in healthy tissue, healing wounds, and engineered matrices. The goal of the present study is to establish dose-response relationships between stretch parameters (magnitude and duration per day) and matrix remodeling metrics (compaction, strength, extensibility, collagen content, contraction, and cellularity). Cyclic equibiaxial stretch of 2-16% was applied to fibroblast-populated fibrin gels for either 6 h or 24 h/day for 8 days. Trends in matrix remodeling metrics as a function of stretch magnitude and duration were analyzed using regression analysis. The compaction and ultimate tensile strength of the tissues increased in a dose-dependent manner with increasing stretch magnitude, yet remained unaffected by the duration in which they were cycled (6 h/day versus 24 h/day). Collagen density increased exponentially as a function of both the magnitude and duration of stretch, with samples stretched for the reduced duration per day having the highest levels of collagen accumulation. Cell number and failure tension were also dependent on both the magnitude and duration of stretch, although stretch-induced increases in these metrics were only present in the samples loaded for 6 h/day. Our results indicate that both the magnitude and the duration per day of stretch are critical parameters in modulating fibroblast remodeling of the extracellular matrix, and that these two factors regulate different aspects of this remodeling. These findings move us one step closer to fully characterizing culture conditions for tissue equivalents, developing improved wound healing treatments and understanding tissue responses to changes in mechanical environments during growth, repair, and disease states.

    Hole expansion tests are commonly used to characterize the edge stretching limit of a material. Traditionally, a conical punch is used to expand a punched hole until a through-thickness crack appears. However, many automotive stretch flanging operations involve in-plane edge stretching that is best captured with a flat punch. In this paper, hole expansion tests were carried out on two different hot-rolled multiphase steels using both flat and conical punches. The fracture mechanisms for both punch types were investigated using scanning electron microscopy (SEM)

    An aspect of proactive safety management is learning lessons from unforeseen events. As BNFL has expanded and extended its nuclear services to many more sites, the potential for organisational learning has grown, but sharing through informal networking has become progressively harder. This potential problem has been solved by implementing formalised company-wide arrangements to turn incidents and accidents into organisational learning opportunities through a system called 'Learning from Experience' (LFE). LFE enables event causes and corrective actions to be identified and shared across all BNFL's sites, initially in the UK but ultimately throughout the world. The result is prevention of events having similar causes, and development of a learning culture which breaks down the barriers to adopting best practice'. Key aspects of the system are: Applying root cause analysis to all significant events; Logging all events, their causes and corrective actions onto a Company-wide database; Screening the database regularly by locally appointed Feedback Co-ordinators trained in identifying learning opportunities and knowledgeable of their own business area, and; Placing and tracking actions to prevent similar events at local Event Review Meetings. The paper describes the implementation and initial experience in operation of the LFE system, which is seen as a significant step towards becoming an expanding and learning company with no accidents or incidents.

    Acute fibrinous and organising pneumonia (AFOP) is a rare histological pattern of interstitial lung disease. The authors describe a 60-year-old woman admitted to the hospital for sustained fever, presenting with an alveolar opacity on chest X-ray, with the presumed diagnosis of community-acquired pneumonia and the onset of antibiotics. Since serological results suggested that Legionella pneumophila was the infectious agent, she was discharged on levofloxacin. A week later, she was again admitted with fever. CT scan showed opacities with crescentic morphology and a central ground-glass area suggestive of cryptogenic organising pneumonia. Microbiological, serological and autoimmunity tests were negative. She underwent surgical lung biopsy that revealed inflammatory infiltrate, macrophage desquamation, fibroblasts proliferation and fibrin deposition in the alveolar spaces, consistent with AFOP. She started corticotherapy with good response. Disease relapsed after prednisolone discontinuation, 10 months later. Currently, the patient is on prednisolone 5 mg/day without clinical and radiological recurrence. © BMJ Publishing Group Ltd (unless otherwise stated in the text of the article) 2017.

    Full Text Available The paper discusses the impact of organisational polities on IT strategy formulation and implementation in an organisation. The objective is to determine the extent of organisational polities on strategy implementation in an organisation. The paper considered the interplay between stakeholders in influencing IT strategy formulation and implementation in an organisation as a socially constructed phenomenon. Thus, the phenomenon can be interpreted and understood by using social theories such Structuration Theory. Hence the paper adopted ANT as a lens through which to understand and interpret the sociotechnical processes associated with IT strategy formulation and implementation in an organisation. Through IT strategy, many organisations attempt to set out key directions and objectives for the use and management of information, communication and technologies. A shared view among these organisations is that IT strategy allows all parts of the organisation to gain a shared understanding of priorities, goals and objectives for both current and future states as defined in the organisational strategy. It is therefore arguable that IT strategy, for the foreseeable future will remain a key aspect of development within organisations. As a result, there has been more focus on how IT strategy is formulated and articulated. What is missing though, is less attention to the implementation of it. Using interpretive research philosophy and employing semi-structured interviews as data collection instrument, this paper attempts to suggest a matrix that will assist organisation to comprehend and deal with organisational politics to reduce its negative impact on IT strategy formulation and implementation in an organisation

    2015-12-01

    In ancient times as well as in the Middle Ages treatment options for discogenic nerve compression syndrome were limited and usually not very specific because of low anatomical and pathophysiological knowledge. The stretch rack (scamnum Hippocratis) was particularly prominent but was widely used as a therapeutic device for very different spinal disorders. Since the beginning of the nineteenth century anatomical knowledge increased and the advances in the fields of asepsis, anesthesia and surgery resulted in an increase in surgical interventions on the spine. In 1908 the first successful lumbar discectomy was initiated and performed by the German neurologist Heinrich O. Oppenheim (1858-1919) and the surgeon Fedor Krause (1857-1937); however, neither recognized the true pathological condition of discogenic nerve compression syndrome. With the landmark report in the New England Journal of Medicine in 1934, the two American surgeons William Jason Mixter (1880-1958) and Joseph Seaton Barr (1901-1963) finally clarified the pathomechanism of lumbar disc herniation and furthermore, propagated discectomy as the standard therapy. Since then interventions on intervertebral discs rapidly increased and the treatment options for lumbar disc surgery quickly evolved. The surgical procedures changed over time and were continuously being refined. In the late 1960s the surgical microscope was introduced for spinal surgery by the work of the famous neurosurgeon Mahmut Gazi Yasargil and his colleague Wolfhard Caspar and so-called microdiscectomy was introduced. Besides open discectomy other interventional techniques were developed to overcome the side effects of surgical procedures. In 1964 the American orthopedic surgeon Lyman Smith (1912-1991) introduced chemonucleolysis, a minimally invasive technique consisting only of a cannula and the proteolytic enzyme chymopapain, which is injected into the disc compartment to dissolve the displaced disc material. In 1975 the Japanese orthopedic

    We experimentally study spreading of the Belousov-Zhabotinsky reaction behind a bluff body in a laminar flow. Locations of reacted regions (i.e., regions with high product concentration) correlate with a moderate range of Lagrangian stretching and that range is close to the range of optimal stretching previously observed in topologically different flows [T. D. Nevins and D. H. Kelley, Phys. Rev. Lett. 117, 164502 (2016)]. The previous work found optimal stretching in a closed, vortex dominated flow, but this article uses an open flow and only a small area of appreciable vorticity. We hypothesize that optimal stretching is common in advection-reaction-diffusion systems with an excitation threshold, including excitable and bistable systems, and that the optimal range depends on reaction chemistry and not on flow shape or characteristic speed. Our results may also give insight into plankton blooms behind islands in ocean currents.

    2005-01-01

    Advanced High Strength Steels (AHSS) are currently being considered for use in closure and structural panels in the automotive industry because of their high potential for affordable weight reduction and improved performance. AHSS such as dual phase steels are currently being used in some vehicle platforms. From a manufacturing perspective, stretch flanging during stamping is an important deformation mode requiring careful consideration of geometry and the die process. This paper presents some geometric and process guidelines for stretch flanging AHSS. Hole expansion experiments were conducted to determine the failure limit for a sheared edge condition. Effects of punching clearance, prestrain and prior strain path on hole expansion were explored in these experiments. In addition, dynamic explicit FE calculations using LS-DYNA were also conducted for a typical stretch flange by varying some key geometric parameters. The experimental and FEA results were then analyzed to yield process and geometric guidelines to enable successful stretch flanging of AHSS

    2005-12-01

    A multi-scale finite element (FE)-damage percolation model was employed to simulate stretch flange forming of aluminum alloys AA5182 and AA5754. Material softening and strain gradients were captured using a Gurson-based FE model. FE results were then fed into the so-called damage percolation code, from which the damage development was modelled within measured microstructures. The formability of the stretch flange samples was predicted based upon the onset of catastrophic failure triggered by profuse void coalescence within the measured second-phase particle field. Damage development is quantified in terms of crack and void areal fractions, and compared to metallographic results obtained from interrupted stretch flange specimens. Parametric study is conducted on the effect of void nucleation strain in the prediction of formability of stretch flanges to "calibrate" proper nucleation strains for both alloys.

    Organisational change occurs when an organisation makes a transition from its current state to some desired future state in minimising employee resistance and cost to the organisation while simultaneously maximising the effectiveness of the change effort. This paper, aims at appraising the change management of organisation in Malaysia since limited research has been done to examine readiness for change by the employees in the organisation. This paper is materialising its objectives of (1) investigating the current practice of organisation and employees in the organisation towards change management and (2) assessing the factors influencing readiness of organisation and employees in the organisation towards change management. It is found via literature review that change management is a structured approach for ensuring that changes are thoroughly and smoothly implemented to transitioning individuals, teams, and organisations to a desired future state by focusing on the wider impacts of change, particularly on people, where change does not happen in isolation and it impacts the whole organisation. Furthermore, it is found that current practice of organisation and employees in the organisation towards change management involved in three main factors, namely trust in management, communication and organisational commitment; with the factor for trust in management is the positive vision for the future by management team, meanwhile for communication, it is found that there is good communication between supervisors and employees about the organisation's policy toward the changes. The factor found in organisational commitment is employees enjoying discussing about their organisation with outsiders. The findings of this paper provide a positive impact on change management planning, which ultimately help in ensuring more effective change programme implementation in the organisation in Malaysia.

  20. Protein domain organisation: adding order

    Full Text Available Abstract Background Domains are the building blocks of proteins. During evolution, they have been duplicated, fused and recombined, to produce proteins with novel structures and functions. Structural and genome-scale studies have shown that pairs or groups of domains observed together in a protein are almost always found in only one N to C terminal order and are the result of a single recombination event that has been propagated by duplication of the multi-domain unit. Previous studies of domain organisation have used graph theory to represent the co-occurrence of domains within proteins. We build on this approach by adding directionality to the graphs and connecting nodes based on their relative order in the protein. Most of the time, the linear order of domains is conserved. However, using the directed graph representation we have identified non-linear features of domain organization that are over-represented in genomes. Recognising these patterns and unravelling how they have arisen may allow us to understand the functional relationships between domains and understand how the protein repertoire has evolved. Results We identify groups of domains that are not linearly conserved, but instead have been shuffled during evolution so that they occur in multiple different orders. We consider 192 genomes across all three kingdoms of life and use domain and protein annotation to understand their functional significance. To identify these features and assess their statistical significance, we represent the linear order of domains in proteins as a directed graph and apply graph theoretical methods. We describe two higher-order patterns of domain organisation: clusters and bi-directionally associated domain pairs and explore their functional importance and phylogenetic conservation. Conclusion Taking into account the order of domains, we have derived a novel picture of global protein organization. We found that all genomes have a higher than expected

    Eighteen healthy male adults were assigned to either an intervention or control group. Isogai dynamic therapy (IDT) is one of Japanese stretching interventions and has been practiced for over 70 years. However, its scientific quantitative evidence remains unestablished. The objective of this study was to determine whether IDT could modify lumbar curvature in healthy young adults compared with stretching exercises used currently in clinical practice. None of previous studies have provided data that conventional stretching interventions could modify spinal curvatures. However, this study provides the first evidence that a specific form of a Japanese stretching intervention can acutely modify the spinal curvatures. We compared the effects of IDT, a Japanese stretching intervention (n=9 males), with a conventional stretching routine (n=9 males) used widely in clinics to modify pelvic tilt and lumbar lordosis (LL) angle. We measured thoracic kyphosis (TK) and LL angles 3 times during erect standing using the Spinal Mouse before and after each intervention. IDT consisted of: (1) hip joint correction, (2) pelvic tilt correction, (3) lumbar alignment correction, and (4) squat exercise stretch. The control group performed hamstring stretches while (1) standing and (2) sitting. IDT increased LL angle to 25.1 degrees (±5.9) from 21.2 degrees (±6.9) (P=0.047) without changing TK angle (pretest: 36.8 degrees [±6.9]; posttest: 36.1 degrees [±6.5]) (P=0.572). The control group showed no changes in TK (P=0.819) and LL angles (P=0.744). IDT can thus be effective for increasing LL angle, hence anterior pelvic tilt. Such modifications could ameliorate low back pain and improve mobility in old adults with an unfavorable pelvic position.

    In the area of business continuity management, a preliminary review of the literature reveals extensive knowledge, expertise and experience concerning organisations in the private and public sectors. It is interesting to note, however, that there is little literature about business continuity management in international organisations, although these entities are complex and particularly prone to threats. This apparent absence of literature suggests that business continuity management has not yet hit the agenda of international organisations. In recent years, member states have encouraged senior management to design and implement business continuity strategies to minimise the mishandling of an internal crisis and build organisational resilience, but very few of them have actually been able to design and implement comprehensive business continuity programmes. Based on actual experience working in international organisations, this paper outlines some of the challenges faced by international organisations in developing and implementing business continuity activities and attempts to make suggestions for further improvement.

    Understanding the effects of the mechanical environment on wound healing is critical for developing more effective treatments to reduce scar formation and contracture. The aim of this study was to investigate the effects of dynamic mechanical stretch on cell-mediated early wound remodeling independent of matrix alignment which obscures more subtle remodeling mechanisms. Cyclic equibiaxial stretch (16% stretch at 0.2 Hz) was applied to fibroblast-populated fibrin gel in vitro wound models for eight days. Compaction, density, tensile strength, and collagen content were quantified as functional measures of remodeling. Stretched samples were approximately ten times stronger, eight-fold more dense, and eight times thinner than statically cultured samples. These changes were accompanied by a 15% increase in net collagen but no significant differences in cell number or viability. When collagen crosslinking was inhibited in stretched samples, the extensibility increased and the strength decreased. The apparent weakening was due to a reduction in compaction rather than a decrease in ability of the tissue to withstand tensile forces. Interestingly, inhibiting collagen crosslinking had no measurable effects on the statically cultured samples. These results indicate that amplified cell-mediated compaction and even a slight addition in collagen content play substantial roles in mechanically induced wound strengthening. These findings increase our understanding of how mechanical forces guide the healing response in skin, and the methods employed in this study may also prove valuable tools for investigating stretch-induced remodeling of other planar connective tissues and for creating mechanically robust engineered tissues.

    The expected positive link between diversity management and organisational efficiency is often used as a reason for pursuing diversity management and equal employment opportunity programmes. However, this positive link is only supported to a limited degree by in-depth empirical research...... and therefore it is often based on normative expectations. Recent research has further indicated that the link between diversity and efficiency may be more complex and cannot a priori be taken for granted. This article argues that some theoretical rethinking of the issues is necessary and suggests...... that the combination of more theoretical cross fertilisation and in-depth research may be the way forward. Based on our own empirical research, barriers preventing a positive link between diversity and efficiency can come in different forms and our case studies illustrate situations where both containing...

The single case being a Defence School of Health Care Studies (DSHCS) and the multiple units of analysis: student nurses, the lecturers and Student Standing Orders. An in depth three dimensional picture was achieved using multiple data collection methods: interview, survey, observation and document analysis. The findings suggest that the DSHCS is perceived to be a sub-culture within a dominant civilian learning culture. Generally, the students and staff believed that the DSHCS is an excellent learning environment and that the defence students overall are high achievers. The common themes that appeared from the data were image, ethos, environment, discipline, support, welfare and a civilian versus military way of thinking. The learning experience of defence student nurses is very positive and enhanced by the positive learning culture of the civilian Higher Educational Institution. The factors influencing a positive learning experience that can be impacted by the overarching culture are discipline, image, ethos of adult learning, support and welfare.

    2013-09-01

    Full Text Available The primary goal of all organisations is efficiency of human resources. Therefore activities as HR controlling, performance management but also cutting costs are the main theme. Current organisations need to monitor human resources to keep their competitiveness. Thus paper describes the key factor of organisational efficiency - employee education, talent management and the necessity to retain skilled employees. The aim of the paper is to reveal the current approach in organisations to education and learning based on primary survey of employees. The data were collected using quantitative primary survey in Czech organisations across sectors. The questionnaire was compiled based on the theoretical background. The paper has been processed based on the analysis of secondary sources, outcome synthesis and the evaluation of results of a questionnaire survey. The data were analysed using descriptive statistic, correlation analysis and factor analysis. The SPSS programme was used for the analyses. The outcomes were categorized and the analyses revealed the main factors affecting organisational approach to employee learning and development. The results identify three possible approaches in organisations to employee learning and development. The first type of organisations educates employees by their own rules, second type does not support education of employees in any way, it is only an interest of employees themselves and thirdly knowledgeable employees were identified as those employees do as much as possible to learn and grow and they choose job position in order to develop constantly. The results can be taken into account in further analysis and in organisation of adult education.

    A survey of nurses working with older adults across three NHS trusts was conducted to explore how perceptions of the workplace affect nurse wellbeing. Standardised validated measures were used to assess burnout, perceived organisational support and organisational culture. Significant associations were found between innovative organisational culture and nurses' sense of personal accomplishment, which reduce the likelihood of burnout. Multiple regression showed experience of burnout to be predicted by the nature of organisational culture. It seems therefore that nurses' wellbeing may be affected by their perceptions of the working environment. Applications of this knowledge and suggestions for future research are discussed.

  13. Organisational Learning: Theoretical Shortcomings and Practical Challenges

    Directory of Open Access Journals (Sweden)

    Jon Aarum Andersen

    2014-05-01

    Full Text Available This paper addresses two problems related to learning and the use of knowledge at work. The first problem is the theoretical shortcomings stemming from the controversy between three different concepts of ‘organisational learning.’ In order to enhance scholarship in this field the notion that organisations - as organisations - can learn need to be rejected for theoretical and empirical reasons. The metaphorical use of ‘organisational learning’ creates only confusion. Learning is a process and knowledge is the outcome of that process. It is argued that learning and knowledge is only related to individuals. Knowledge is thus the individual capability to draw distinctions, within a domain of action, based on an appreciation of context or theory. Consequently, knowledge becomes organisational when it is created, developed and transmitted to other individuals in the organisation. In a strict sense knowledge becomes organisational when employees use it and act based on generalisations due to the rules and procedures found in their organisation. The gravest problem is practical challenges due to the fact that the emphasis on learning, knowledge and competence of the working force do not materialize in the application of the knowledge acquired. It is evident that employees do not use their increased knowledge. However, we do not know why they do not use it. An enormous waste of money is spent on learning and knowledge in organisations which does not yield what is expected. How can managers act in order to enhance the application of increased knowledge possessed by the workforce?

    1976-01-01

    SBARMO (Scientific Ballooning and Radiations Monitoring Organisation), known as SPARMO (Solar Particles and Radiations Monitoring Organisation) until 1973, was established in 1961, mainly for the purpose of coordinating balloon-borne measurements of solar energetic particles. The study of auroral X-rays has gradually replaced the study of energetic solar particles as the prime interest of the organisation. The change of name, as adopted during the 1972 Meeting in Graz (Austria) is a logical consequence of the more general orientation of the organisation. The international status of SBARMO is emphasized by its membership of the Federation of Astronomical and Geophysical Services (FAGS) of the International Council of Scientific Unions

    Full Text Available Orientation: Understanding cyberloafing, organisational justice, work engagement and organisational trust will lead organisations to develop strategies to counter the consequences of cyberloafing. Research purpose: This research explored the relationships between cyberloafing, organisational justice, work engagement and organisational trust among South African office workers in the retail and manufacturing industry. Motivation for the study: Cyberloafing, a prevalent way for office employees to engage in non-work-related activities during work time, is considered harmful to organisations. Limited research exists about the relationship between cyberloafing and organisational justice, organisational trust and work engagement within South Africa. Research design, approach and method: A quantitative research design was followed. Questionnaires were administered in the South African retail and manufacturing industry; a convenient sample of N = 224 was obtained. Descriptive statistics, Cronbach’s alpha coefficients, structural equation modelling and bootstrapping were used for data analysis. Main findings: Organisational justice was positively related to organisational trust while organisational trust was positively related to work engagement; work engagement related negatively to cyberloafing. Organisational trust mediated the relationship between organisational justice and work engagement while work engagement mediated the relationship between organisational trust and cyberloafing. Practical and managerial implications: Strategies can be developed to enhance and warrant perceptions of organisational justice and fairness that will increase trust levels, leading to higher work engagement and decreased cyberloafing behaviour and resulting in higher productivity. Contribution or value-add: The research revealed that when employees perceive their organisations as being fair, organisational trust will increase, leading to heightened work

  18. The effect of warm-up, static stretching and dynamic stretching on hamstring flexibility in previously injured subjects.

    2009-01-01

    BACKGROUND: Warm-up and stretching are suggested to increase hamstring flexibility and reduce the risk of injury. This study examined the short-term effects of warm-up, static stretching and dynamic stretching on hamstring flexibility in individuals with previous hamstring injury and uninjured controls. METHODS: A randomised crossover study design, over 2 separate days. Hamstring flexibility was assessed using passive knee extension range of motion (PKE ROM). 18 previously injured individuals and 18 uninjured controls participated. On both days, four measurements of PKE ROM were recorded: (1) at baseline; (2) after warm-up; (3) after stretch (static or dynamic) and (4) after a 15-minute rest. Participants carried out both static and dynamic stretches, but on different days. Data were analysed using Anova. RESULTS: Across both groups, there was a significant main effect for time (p < 0.001). PKE ROM significantly increased with warm-up (p < 0.001). From warm-up, PKE ROM further increased with static stretching (p = 0.04) but significantly decreased after dynamic stretching (p = 0.013). The increased flexibility after warm-up and static stretching reduced significantly (p < 0.001) after 15 minutes of rest, but remained significantly greater than at baseline (p < 0.001). Between groups, there was no main effect for group (p = 0.462), with no difference in mean PKE ROM values at any individual stage of the protocol (p > 0.05). Using ANCOVA to adjust for the non-significant (p = 0.141) baseline difference between groups, the previously injured group demonstrated a greater response to warm-up and static stretching, however this was not statistically significant (p = 0.05). CONCLUSION: Warm-up significantly increased hamstring flexibility. Static stretching also increased hamstring flexibility, whereas dynamic did not, in agreement with previous findings on uninjured controls. The effect of warm-up and static stretching on flexibility was greater in those with reduced

    This study investigated exercise-induced effects of static stretching and playing soccer on anterior tibial translation (ATT) of the knee joint. Randomized controlled trial. University biomechanics laboratory. Thirty-one athletes were randomly assigned into a stretching (26.9 ± 6.2 years, 1.77 ± 0.09 m, 67.9 ± 10.7 kg) and a control group (27.9 ± 7.4 years, 1.75 ± 0.08 m, 72.0 ± 14.9 kg). Thirty-one amateur soccer players in an additional soccer group (25.1 ± 5.6 years, 1.74 ± 0.10 m, 71.8 ± 14.8 kg). All participants had no history of knee injury requiring surgery and any previous knee ligament or cartilage injury. The stretching group performed 4 different static stretching exercises with a duration of 2 × 20 seconds interspersed with breaks of 10 seconds. The soccer group completed a 90-minute soccer-specific training program. The control group did not perform any physical activity for approximately 30 minutes. Anterior tibial translation was measured with the KT-1000 knee arthrometer at forces of 67 N, 89 N, and maximal manual force (Max) before and after the intervention. There was a significant increase in ATT after static stretching and playing soccer at all applied forces. Maximal manual testing revealed a mean increase of ATT after static stretching of 2.1 ± 1.6 mm (P soccer of 1.0 ± 1.5 mm (P = 0.001). The ATT increase after static stretching at 67 and 89 N is significantly higher than in controls. At maximum manual testing, significant differences were evident between all groups. Static stretching and playing soccer increase ATT and may consequently influence mechanical factors of the anterior cruciate ligament. The ATT increase after static stretching was greater than after playing soccer. The observed increase in ATT after static stretching and playing soccer may be associated with changes in kinesthetic perception and sensorimotor control, activation of muscles, joint stability, overall performance, and higher injury risk.

    Mari Huhtala

    2016-04-01

    Full Text Available Following the Job Demands-Resources model’s motivational process, this study investigates the role of person-organisation fit and work engagement as mediating processes between ethical culture and employee commitment, where ethical culture is seen as an organisational resource. It was expected that the stronger the ethical values and practices are experienced to be, the more compatible employees feel with the organisation. A good person-organisation fit was further hypothesised to act as a personal job resource for the employees, who would consequently experience higher work engagement leading to stronger affective commitment and less turnover intentions. The study used questionnaire data gathered from 270 Finnish school psychologists. The analyses were performed by using SEM and mediation modelling with the bootstrapping method. Ethical organisational culture had a significant positive association with experienced person-organisation fit, which in turn was related to higher work engagement. Both person-organisation fit and work engagement were associated with higher affective commitment and with lower turnover intentions. This study contributes to understanding the mechanisms through which ethical culture affects employee commitment by integrating the concept of person-organisation fit with the Job Demands-Resources model. Organisations can retain committed and motivated workforce through fostering a strong ethical culture, which can support employees’ affective commitment to the organisation.

    Directory of Open Access Journals (Sweden)

    Jürgen Rausch

    2007-01-01

    Full Text Available For 1500 years, the monastic life of the Benedictines has been defined by rules dating from the time of the first foundation of the order, suggesting an organizational structure that has outlasted historical upheavals and changes. Starting from a new understanding of organisational development as organisational learning, Karin REIBER has looked for clues to organisational formation and learning through a hermeneutic textual analysis of the Regula Benedicti of the 6th Century. Within a theoretical framework, REIBER develops three dimensions of organisational formation and three stages of organisational learning. In a historical reconstruction, the author analyses the text of the Regula Benedicti. In a second section, REIBER adapts and interprets the results of the hermeneutic analysis through a double three-stage theoretical model. She works out interesting aspects for organisational learning, which relate individual learning to organisational learning in favour of members of the organisation, for which consideration for individuality forms a part of the leadership concept and as a framework for social relationships, establishing an informal organisational structure beside the formal one. This illuminating work leads to an integrated concept of organisational learning, which extends the notion of tradition as a characteristic feature of an innovative organisation and which, through continuity and topicality, can hence guarantee the continued existence of modern organisations in the future.

    Strategies to implement evidence-based practice have highlighted the bidirectional relationship of organisational change on organisational culture. The present study examined changes in perceptions of organisational culture in two community mental health services implementing cognitive therapies into routine psychosis care over 3 years. During the time of the study there were a number of shared planned and unplanned changes that the mental health services had to accommodate. One service, Metro South, had the additional challenge of embarking on a major organisational restructure. A survey of organisational culture was administered to clinical staff of each service at yearly intervals over the 3 years. At baseline assessment there was no significant difference between the two services in organisational culture. At the midpoint assessment, which was conducted at the time the Metro South restructure was operationalized, there were less positive ratings of organisational culture recorded in Metro South compared to the other service. Organisational culture returned to near-baseline levels at endpoint assessment. These findings are consistent with the literature that organisational culture is relatively robust and resilient. It is also consistent with the literature that, at any one time, a service or organisation may have a finite capacity to absorb change. Consequently this limitation needs to be taken into account in the timing and planning of major service reform where possible. The results also extend the literature, insofar as external factors with a high impact on the operation of an organisation may impact upon organisational culture albeit temporarily.

  17. A Model of Project and Organisational Dynamics

    Directory of Open Access Journals (Sweden)

    Jenny Leonard

    2012-04-01

    Full Text Available The strategic, transformational nature of many information systems projects is now widely understood. Large-scale implementations of systems are known to require significant management of organisational change in order to be successful. Moreover, projects are rarely executed in isolation – most organisations have a large programme of projects being implemented at any one time. However, project and value management methodologies provide ad hoc definitions of the relationship between a project and its environment. This limits the ability of an organisation to manage the larger dynamics between projects and organisations, over time, and between projects. The contribution of this paper, therefore, is to use literature on organisational theory to provide a more systematic understanding of this area. The organisational facilitators required to obtain value from a project are categorised, and the processes required to develop those facilitators are defined. This formalisation facilitates generalisation between projects and highlights any time and path dependencies required in developing organisational facilitators. The model therefore has the potential to contribute to the development of IS project management theory within dynamic organisational contexts. Six cases illustrate how this model could be used.

  7. Cyclic Stretch Alters Vascular Reactivity of Mouse Aortic Segments

    Directory of Open Access Journals (Sweden)

    2017-10-01

    Full Text Available Large, elastic arteries buffer the pressure wave originating in the left ventricle and are constantly exposed to higher amplitudes of cyclic stretch (10% than muscular arteries (2%. As a crucial factor for endothelial and smooth muscle cell function, cyclic stretch has, however, never been studied in ex vivo aortic segments of mice. To investigate the effects of cyclic stretch on vaso-reactivity of mouse aortic segments, we used the Rodent Oscillatory Tension Set-up to study Arterial Compliance (ROTSAC. The aortic segments were clamped at frequencies of 6–600 bpm between two variable preloads, thereby mimicking dilation as upon left ventricular systole and recoiling as during diastole. The preloads corresponding to different transmural pressures were chosen to correspond to a low, normal or high amplitude of cyclic stretch. At different time intervals, cyclic stretch was interrupted, the segments were afterloaded and isometric contractions by α1-adrenergic stimulation with 2 μM phenylephrine in the absence and presence of 300 μM L-NAME (eNOS inhibitor and/or 35 μM diltiazem (blocker of voltage-gated Ca2+ channels were measured. As compared with static or cyclic stretch at low amplitude (<10 mN or low frequency (0.1 Hz, cyclic stretch at physiological amplitude (>10 mN and frequency (1–10 Hz caused better ex vivo conservation of basal NO release with time after mounting. The relaxation of PE-precontracted segments by addition of ACh to stimulate NO release was unaffected by cyclic stretch. In the absence of basal NO release (hence, presence of L-NAME, physiological in comparison with aberrant cyclic stretch decreased the baseline tension, attenuated the phasic contraction by phenylephrine in the absence of extracellular Ca2+ and shifted the smaller tonic contraction more from a voltage-gated Ca2+ channel-mediated to a non-selective cation channel-mediated. Data highlight the need of sufficient mechanical activation of endothelial and

    Full Text Available This study aimed to examine the effect of different stretching exercises on vertical jump performance. A total of 14 national male athletes sporting in the elite level took part in the study. The age average of the participants was 20.25±1.03 year, the average height was 1.80±.08 m, the average body weight was 77.14±18.91 kg, average of sporting age was 9.87±3.31 year and the average number of participation in international games was 10.0±3.31. As stretching protocol: Method 1 (5 minutes of jogging and 2 minutes of active rest followed by Method 2 (static stretching for 4 different muscle groups 3 repetitions for 15 seconds of static stretching, rest for 10 seconds between groups and then consecutively, Method 3 (Dynamic stretching exercises with 3 repetitions for 15 seconds and 10 seconds rest between different muscle groups were applied in the study. The vertical jump performance before and after different stretching exercises of the participants was determined by means of the vertical jump test using the smart speed lite system. Before and after the training of all athletes, HR was recorded with a heart rate monitor (RS 800, Polar Vantage NV, Polar Electro Oy, Finland with 5 seconds intervals. Before the study, the chest band of the heartbeat monitor was placed on the chest of the athlete and the HR was recorded from the monitor. SPSS 15.0 statistical package program was used for evaluation and calculation of the data. In this study in addition to descriptive statistics (mean and standard deviation paired samples t-test was used to determine the difference between the vertical jump performance of the participants before and after different stretching exercises. As a result, this study showed that; applying the dynamic and static stretching exercises consecutively affected the vertical jump performance 4.5 cm positively (p<.05. It is suggested that different dynamic and static stretching exercises should be included in the vertical jump.

    Full Text Available The purpose of this study was to examine the acute and chronic effects of static & dynamic stretching protocols on agility performance in amateur handball players. Twelve male amateur handball players (age: 19.66 ± 4.02 years old, weight: 67.12 ± 8.73 kg, height: 178.29 ± 7.81 cm participated in this study. The athletes were randomly allocated into two groups: static stretching or dynamic stretching. All of them underwent an initial evaluation and were submitted to the first intervention. They were evaluated once again and at the end of 12 training sessions. The results analyzed using ANOVA showed that there was a significant decrease in agility time after dynamic stretching against no stretching in the acute phase; but, there were no significant differences between dynamic stretching and no stretching in the chronic phase. In addition, there was no a significant difference between no stretching and static stretching in the acute phase; while, There was a significant decrease in agility time after no stretching against static stretching in the chronic phase. It was concluded that acute dynamic stretching as part of a warm-up may decrease agility time performance, whereas static stretching seems to increase agility time performance. Consequently, the acute and chronic static stretching should not be performed prior to an explosive athletic performance. Keywords: Handball, Agility, Dynamic stretching, Static stretching

    2015-08-01

    In spastic paresis, stretch applied to the antagonist increases its inappropriate recruitment during agonist command (spastic co-contraction). It is unknown whether antagonist stretch: (1) also affects agonist recruitment; (2) alters effort perception. We quantified voluntary activation of ankle dorsiflexors, effort perception, and plantar flexor co-contraction during graded dorsiflexion efforts at two gastrocnemius lengths. Eighteen healthy (age 41 ± 13) and 18 hemiparetic (age 54 ± 12) subjects performed light, medium and maximal isometric dorsiflexion efforts with the knee flexed or extended. We determined dorsiflexor torque, Root Mean Square EMG and Agonist Recruitment/Co-contraction Indices (ARI/CCI) from the 500 ms peak voluntary agonist recruitment in a 5-s maximal isometric effort in tibialis anterior, soleus and medial gastrocnemius. Subjects retrospectively reported effort perception on a 10-point visual analog scale. During gastrocnemius stretch in hemiparetic subjects, we observed: (1) a 25 ± 7 % reduction of tibialis anterior voluntary activation (maximum reduction 98 %; knee extended vs knee flexed; p = 0.007, ANOVA); (2) an increase in dorsiflexion effort perception (p = 0.03, ANCOVA). Such changes did not occur in healthy subjects. Effort perception depended on tibialis anterior recruitment only (βARI(TA) = 0.61, p hemiparesis, voluntary ability to recruit agonist motoneurones is impaired--sometimes abolished--by antagonist stretch, a phenomenon defined here as stretch-sensitive paresis. In addition, spastic co-contraction increases effort perception, an additional incentive to evaluate and treat this phenomenon.

    Stretching of porcine carotid arterial muscle increased the phosphorylation of the 20 kDa myosin light chain from 0.23 to 0.68 mol [32P]phosphate/mol light chain, whereas stretching of phorbol dibutyrate treated muscle increased the phosphorylation from 0.30 to 0.91 mol/mol. Two-dimensional gel electrophoresis followed by two-dimensional tryptic phosphopeptide mapping was used to identify the enzyme involved in the stretch-induced phosphorylation. Quantitation of the [32P]phosphate content of the peptides revealed considerable light chain phosphorylation by protein kinase C only in the phorbol dibutyrate treated arterial muscle, whereas most of the light chain phosphorylation was attributable to myosin light chain kinase. Upon stretch of either the untreated or treated muscle, the total increment in [32P]phosphate incorporation into the light chain could be accounted for by peptides characteristic for myosin light chain kinase catalyzed phosphorylation, demonstrating that the stretch-induced phosphorylation is caused by this enzyme exclusively

    A number of potassium channels including members of the KCNQ family and the Ca(2+) activated IK and SK, but not BK, are strongly and reversibly regulated by small changes in cell volume. It has been argued that this general regulation is mediated through sensitivity to changes in membrane stretch...... was not affected by membrane stretch. The results indicate that (1) activation of BK channels by local membrane stretch is not mimicked by membrane stress induced by cell swelling, and (2) activation of KCNQ1 channels by cell volume increase is not mediated by local tension in the cell membrane. We conclude....... To test this hypothesis we have studied the regulation of KCNQ1 and BK channels after expression in Xenopus oocytes. Results from cell-attached patch clamp studies (approximately 50 microm(2) macropatches) in oocytes expressing BK channels demonstrate that the macroscopic volume-insensitive BK current...

  17. Directional Cell Migration in Response to Repeated Substratum Stretching

    Science.gov (United States)

    Okimura, Chika; Iwadate, Yoshiaki

    2017-10-01

    Crawling migration plays an essential role in a variety of biological phenomena, including development, wound healing, and immune system function. Migration properties such as anterior-posterior polarity, directionality, and velocity are regulated not only by the reception of a chemoattractant but also by sensing mechanical inputs from the external environment. In this review, we describe the mechanical response of migrating cells, particularly under repeated stretching of the elastic substratum, highlighting the fact that there appear to be two independent mechanosensing systems that generate the polarity needed for migration. Cells that have no stress fibers, such as Dictyostelium cells and neutrophil-like differentiated HL-60 cells, migrate perpendicular to the stretching direction via myosin II localization. Cells that do possess stress fibers, however, such as fish keratocytes, migrate parallel to the stretching via a stress-fiber-dependent process.

  18. Probabilistic model of ligaments and tendons: Quasistatic linear stretching

    Science.gov (United States)

    Bontempi, M.

    2009-03-01

    Ligaments and tendons have a significant role in the musculoskeletal system and are frequently subjected to injury. This study presents a model of collagen fibers, based on the study of a statistical distribution of fibers when they are subjected to quasistatic linear stretching. With respect to other methodologies, this model is able to describe the behavior of the bundle using less ad hoc hypotheses and is able to describe all the quasistatic stretch-load responses of the bundle, including the yield and failure regions described in the literature. It has two other important results: the first is that it is able to correlate the mechanical behavior of the bundle with its internal structure, and it suggests a methodology to deduce the fibers population distribution directly from the tensile-test data. The second is that it can follow fibers’ structure evolution during the stretching and it is possible to study the internal adaptation of fibers in physiological and pathological conditions.

  19. Stretching of red blood cells at high strain rates

    Mancuso, J. E.; Ristenpart, W. D.

    2017-10-01

    Most work on the mechanical behavior of red blood cells (RBCs) in flow has focused on simple shear flows. Relatively little work has examined RBC deformations in the physiologically important extensional flow that occurs at the entrance to a constriction. In particular, previous work suggests that RBCs rapidly stretch out and then retract upon entering the constriction, but to date no model predicts this behavior for the extremely high strain rates typically experienced there. In this Rapid Communication, we use high speed video to perform systematic measurements of the dynamic stretching behavior of RBCs as they enter a microfluidic constriction. We demonstrate that both the Kelvin-Voigt and Skalak viscoelastic models capture the observed stretching dynamics, up to strain rates as high as 2000 s-1. The results indicate that the effective elastic modulus of the RBC membrane at these strain rates is an order of magnitude larger than moduli measured by micropipette aspiration or other low strain rate techniques.

    Simulations of stretch flange forming operations are undertaken using explicit dynamic finite element calculations incorporating anisotropic yield criteria. Simple circular stretch flanges utilizing a single circular punch to expand the cut-out were considered. Experiments were performed using 101mm diameter tooling on AA 5754 and AA 5182 aluminum alloy sheets, with varying cut-out and gauge size. Metallurgical aspects of the formability of these aluminum alloys and damage mechanisms were studied. Both optical and Scanning Electron Microscopy (SEM) were used to study ductile fracture behaviour in these materials during the forming operation. The limit strains obtained from the circular stretch flange formability experiments are compared to forming limit diagram (FLD) data from hemispherical dome specimens. (author)

  1. The Living Cell as a Multi-agent Organisation: A Compositional Organisation Model of Intracellular Dynamics

    Science.gov (United States)

    Jonker, C. M.; Snoep, J. L.; Treur, J.; Westerhoff, H. V.; Wijngaards, W. C. A.

    Within the areas of Computational Organisation Theory and Artificial Intelligence, techniques have been developed to simulate and analyse dynamics within organisations in society. Usually these modelling techniques are applied to factories and to the internal organisation of their process flows, thus obtaining models of complex organisations at various levels of aggregation. The dynamics in living cells are often interpreted in terms of well-organised processes, a bacterium being considered a (micro)factory. This suggests that organisation modelling techniques may also benefit their analysis. Using the example of Escherichia coli it is shown how indeed agent-based organisational modelling techniques can be used to simulate and analyse E.coli's intracellular dynamics. Exploiting the abstraction levels entailed by this perspective, a concise model is obtained that is readily simulated and analysed at the various levels of aggregation, yet shows the cell's essential dynamic patterns.

    2012-01-01

    Crisis management teams (CMT) are necessary to ensure adequate and appropriate crisis management planning and response to unforeseen, adverse events. This study investigated the existence of CMTs, the membership of CMTs, and the degree of training received by CMTs in Australian health and allied health organisations. This cross-sectional study draws on data provided by executive decision makers in a broad selection of health and allied health organisations. Crisis management teams were found in 44.2 per cent of the health-related organisations surveyed, which is ten per cent lower than the figure for business organisations. Membership of these CMTs was not ideal and did not conform to standard CMT membership profiles. Similarly, the extent of crisis management training in health-related organisations is 20 per cent lower than the figure for business organisations. If organisations do not become pro-active in their crisis management practices, the onus is on government to improve the situation through regulation and the provision of more physical, monetary and skill resources to ensure that the health services of Australia are sufficiently prepared to respond to adverse events.

    Prætorius, Thim

    2016-01-01

    The purpose of this paper is to systematically apply theory of organisational routines to standardised care pathways. The explanatory power of routines is used to address open questions in the care pathway literature about their coordinating and organising role, the way they change and can be replicated, the way they are influenced by the organisation and the way they influence health care professionals. Theory of routines is systematically applied to care pathways in order to develop theoretically derived propositions. Care pathways mirror routines by being recurrent, collective and embedded and specific to an organisation. In particular, care pathways resemble standard operating procedures that can give rise to recurrent collective action patterns. In all, 11 propositions related to five categories are proposed by building on these insights: care pathways and coordination, change, replication, the organisation and health care professionals. Research limitations/implications - The paper is conceptual and uses care pathways as illustrative instances of hospital routines. The propositions provide a starting point for empirical research. The analysis highlights implications that health care professionals and managers have to consider in relation to coordination, change, replication, the way the organisation influences care pathways and the way care pathways influence health care professionals. Originality/value - Theory on organisational routines offers fundamental, yet unexplored, insights into hospital processes, including in particular care coordination.

    Joyce, Pauline

    2009-05-01

    The aim of this paper is to present findings of a case study on organisational effectiveness in an education setting and draw similarities with a healthcare setting, focusing on the school principal and nurse leader. The study was carried out in a primary school setting and focuses on a principal (as leader). The school, which will be named St Senan's for the case study, is a typical tall structure, has a staff of 30 (teachers and special needs' assistants) and a student number of 117. A case study methodology was used. Data was collected by interviewing the principal, two teachers, two students and a parent, in this order. In addition, a Parents' Council meeting was observed and document analysis was carried out on measurements which reflected some critical success factors for the school. Interviews from students and teachers in addition to observation notes indicate that the principal's leadership impacts on organisational effectiveness in the school. The findings are located in the context of education with similarities being drawn from nursing. It is how the leader leads in the context of the organisation setting which is paramount. In other words it is not possible to take a set of general critical success factors for a school or healthcare setting and apply these widely. The paper concludes by proposing the use of a quality framework to contextualise the findings of the case and promote further discussion in the context of nurse leaders. The paper suggests that comparisons can be made between school principals and nurse leaders.

    2010-05-01

    Research purpose: The objective of this study was to explore the relationship between organisational climate and job satisfaction to determine whether employees’ perceptions of the work environment influence their level of job satisfaction. Motivation for the study: Organisations are facing more challenges than ever before. These challenges are not unique to any specific organisation or industry, but affect all organisations.Organisational climate in particular is constantly challenged by changes impacting organisations today. Research design, approach and method: An organisational climate questionnaire was administered to a convenience sample of 696 employees from a population of 1453 employees working in three regions in which the organisation was operational. Confirmatory and exploratory factor analyses were used to investigate the structure of the climate model. Main findings: The revised 12-factor model (after the confirmatory factor analysis fitted the data best and the researchers therefore decided to proceed with the revised 12-factor model (11 dimensions for further analysis. A stepwise regression was conducted and nine dimensions of organisational climate were found to predict job satisfaction. The results indicated a strong positive correlation (r = 0.813, p< 0.01 between organisational climate and the dependent variable of job satisfaction. Practical implications: This study provided support for the view that line managers and human resource practitioners should be aware that different biographical groups have different needs that can influence their job satisfaction levels and different perceptions of the climate within the organisation and that this impacts on their behaviour. Contribution: The findings of this study indicated a positive relationship between organisational climate scores and job satisfaction scores and thus, regardless of how the dimensions are perceived, organisational climate has an influence on job satisfaction.

    Santos, Ana L; Preta, Giulio

    2018-06-01

    Lipids are fundamental building blocks of all cells and play important roles in the pathogenesis of different diseases, including inflammation, autoimmune disease, cancer, and neurodegeneration. The lipid composition of different organelles can vary substantially from cell to cell, but increasing evidence demonstrates that lipids become organised specifically in each compartment, and this organisation is essential for regulating cell function. For example, lipid microdomains in the plasma membrane, known as lipid rafts, are platforms for concentrating protein receptors and can influence intra-cellular signalling. Lipid organisation is tightly regulated and can be observed across different model organisms, including bacteria, yeast, Drosophila, and Caenorhabditis elegans, suggesting that lipid organisation is evolutionarily conserved. In this review, we summarise the importance and function of specific lipid domains in main cellular organelles and discuss recent advances that investigate how these specific and highly regulated structures contribute to diverse biological processes.

    Full Text Available The study presents the implementation of projects in organisations that achieve business objectives through the imple-mentation of repetitive actions. Projects in these organisations are, on the one hand, treated as marginal activities, while the results of these projects have significant impact on the delivery of main processes, e.g. through the introduction of new products. Human capital and solutions in this field bear impact on the success of projects in these organisations, which is not always conducive to smooth implementation of projects. Conflict results from the nature of a project, which is a one-time and temporary process, so organisational solutions are also temporary. It influences on attitudes and com-mitment of the project contractors. The paper identifies and analyses factors which affect the success of the projects.

    Bellomo, R; Finlay, M; McLaughlin, P; Tai, E

    1991-01-01

    Cryptogenic organising pneumonitis (bronchiolitis obliterans organising pneumonia) is an uncommon condition that often responds to steroids. It is characterised clinically by constitutional symptoms, pathologically by intra-alveolar organising fibrosis, and radiologically by patchy pulmonary infiltrates. Its full clinical spectrum and course are only partially described and understood. Six patients are described, seen over three years, with considerably diverse clinical and radiological presentations (two had diffuse lung infiltrates, two had peripheral lung infiltrates, and two had localised lobar involvement) and with very varying severity of disease (two with a life threatening illness, three with appreciable subacute constitutional symptoms, and one with mild symptoms). It is concluded that cryptogenic organising pneumonitis can present in various ways. A set of diagnostic criteria are proposed which will help in the recognition of this syndrome, which is probably underdiagnosed. Images PMID:1926023

  9. Flow of viscous fluid along an exponentially stretching curved surface

    Directory of Open Access Journals (Sweden)

    N.F. Okechi

    Full Text Available In this paper, we present the boundary layer analysis of flow induced by rapidly stretching curved surface with exponential velocity. The governing boundary value problem is reduced into self-similar form using a new similarity transformation. The resulting equations are solved numerically using shooting and Runge-Kutta methods. The numerical results depicts that the fluid velocity as well as the skin friction coefficient increases with the surface curvature, similar trend is also observed for the pressure. The dimensionless wall shear stress defined for this problem is greater than that of a linearly stretching curved surface, but becomes comparably less for a surface stretching with a power-law velocity. In addition, the result for the plane surface is a special case of this study when the radius of curvature of the surface is sufficiently large. The numerical investigations presented in terms of the graphs are interpreted with the help of underlying physics of the fluid flow and the consequences arising from the curved geometry.

  10. Contact of a spherical probe with a stretched rubber substrate

    Frétigny, Christian; Chateauminois, Antoine

    2017-07-01

    We report on a theoretical and experimental investigation of the normal contact of stretched neo-Hookean substrates with rigid spherical probes. Starting from a published formulation of surface Green's function for incremental displacements on a prestretched, neo-Hookean, substrate [J. Mech. Phys. Solids 56, 2957 (2008), 10.1016/j.jmps.2008.07.002], a model is derived for both adhesive and nonadhesive contacts. The shape of the elliptical contact area together with the contact load and the contact stiffness are predicted as a function of the in-plane stretch ratios λx and λy of the substrate. The validity of this model is assessed by contact experiments carried out using an uniaxally stretched silicone rubber. For stretch ratio below about 1.25, a good agreement is observed between theory and experiments. Above this threshold, some deviations from the theoretical predictions are induced as a result of the departure of the mechanical response of the silicone rubber from the neo-Hokeean description embedded in the model.

    The equilibrium of a stretched string in curved space is studied. The problem is first formulated without detailed assumptions, then the force of gravity on the string is calculated from general relativity with a static metric. Apart from the latter calculation everything is done in ordinary space rather than in space-time. A number of simple cases are worked out explicitly. (author)

    Full Text Available Although yoga is an effective treatment for chronic low back pain, little is known about the mechanisms responsible for its benefits. In a trial comparing yoga to intensive stretching and self-care, we explored whether physical (hours of back exercise/week, cognitive (fear avoidance, body awareness, and self-efficacy, affective (psychological distress, perceived stress, positive states of mind, and sleep, and physiological factors (cortisol, DHEA mediated the effects of yoga or stretching on back-related dysfunction (Roland-Morris Disability Scale (RDQ. For yoga, 36% of the effect on 12-week RDQ was mediated by increased self-efficacy, 18% by sleep disturbance, 9% by hours of back exercise, and 61% by the best combination of all possible mediators (6 mediators. For stretching, 23% of the effect was mediated by increased self-efficacy, 14% by days of back exercise, and 50% by the best combination of all possible mediators (7 mediators. In open-ended questions, ≥20% of participants noted the following treatment benefits: learning new exercises (both groups, relaxation, increased awareness, and the benefits of breathing (yoga, benefits of regular practice (stretching. Although both self-efficacy and hours of back exercise were the strongest mediators for each intervention, compared to self-care, qualitative data suggest that they may exert their benefits through partially distinct mechanisms.

  18. Theory of high-force DNA stretching and overstretching.

    Storm, C; Nelson, P C

    2003-05-01

    Single-molecule experiments on single- and double-stranded DNA have sparked a renewed interest in the force versus extension of polymers. The extensible freely jointed chain (FJC) model is frequently invoked to explain the observed behavior of single-stranded DNA, but this model does not satisfactorily describe recent high-force stretching data. We instead propose a model (the discrete persistent chain) that borrows features from both the FJC and the wormlike chain, and show that it resembles the data more closely. We find that most of the high-force behavior previously attributed to stretch elasticity is really a feature of the corrected entropic elasticity; the true stretch compliance of single-stranded DNA is several times smaller than that found by previous authors. Next we elaborate our model to allow coexistence of two conformational states of DNA, each with its own stretch and bend elastic constants. Our model is computationally simple and gives an excellent fit through the entire overstretching transition of nicked, double-stranded DNA. The fit gives the first value for the bend stiffness of the overstretched state. In particular, we find the effective bend stiffness for DNA in this state to be about 12 nm k(B)T, a value quite different from either the B-form or single-stranded DNA.

  5. Force encoding in muscle spindles during stretch of passive muscle.

    Full Text Available Muscle spindle proprioceptive receptors play a primary role in encoding the effects of external mechanical perturbations to the body. During externally-imposed stretches of passive, i.e. electrically-quiescent, muscles, the instantaneous firing rates (IFRs of muscle spindles are associated with characteristics of stretch such as length and velocity. However, even in passive muscle, there are history-dependent transients of muscle spindle firing that are not uniquely related to muscle length and velocity, nor reproduced by current muscle spindle models. These include acceleration-dependent initial bursts, increased dynamic response to stretch velocity if a muscle has been isometric, and rate relaxation, i.e., a decrease in tonic IFR when a muscle is held at a constant length after being stretched. We collected muscle spindle spike trains across a variety of muscle stretch kinematic conditions, including systematic changes in peak length, velocity, and acceleration. We demonstrate that muscle spindle primary afferents in passive muscle fire in direct relationship to muscle force-related variables, rather than length-related variables. Linear combinations of whole muscle-tendon force and the first time derivative of force (dF/dt predict the entire time course of transient IFRs in muscle spindle Ia afferents during stretch (i.e., lengthening of passive muscle, including the initial burst, the dynamic response to lengthening, and rate relaxation following lengthening. Similar to acceleration scaling found previously in postural responses to perturbations, initial burst amplitude scaled equally well to initial stretch acceleration or dF/dt, though later transients were only described by dF/dt. The transient increase in dF/dt at the onset of lengthening reflects muscle short-range stiffness due to cross-bridge dynamics. Our work demonstrates a critical role of muscle cross-bridge dynamics in history-dependent muscle spindle IFRs in passive muscle

  6. Stretching skeletal muscle: chronic muscle lengthening through sarcomerogenesis.

    Directory of Open Access Journals (Sweden)

    Alexander M Zöllner

    Full Text Available Skeletal muscle responds to passive overstretch through sarcomerogenesis, the creation and serial deposition of new sarcomere units. Sarcomerogenesis is critical to muscle function: It gradually re-positions the muscle back into its optimal operating regime. Animal models of immobilization, limb lengthening, and tendon transfer have provided significant insight into muscle adaptation in vivo. Yet, to date, there is no mathematical model that allows us to predict how skeletal muscle adapts to mechanical stretch in silico. Here we propose a novel mechanistic model for chronic longitudinal muscle growth in response to passive mechanical stretch. We characterize growth through a single scalar-valued internal variable, the serial sarcomere number. Sarcomerogenesis, the evolution of this variable, is driven by the elastic mechanical stretch. To analyze realistic three-dimensional muscle geometries, we embed our model into a nonlinear finite element framework. In a chronic limb lengthening study with a muscle stretch of 1.14, the model predicts an acute sarcomere lengthening from 3.09[Formula: see text]m to 3.51[Formula: see text]m, and a chronic gradual return to the initial sarcomere length within two weeks. Compared to the experiment, the acute model error was 0.00% by design of the model; the chronic model error was 2.13%, which lies within the rage of the experimental standard deviation. Our model explains, from a mechanistic point of view, why gradual multi-step muscle lengthening is less invasive than single-step lengthening. It also explains regional variations in sarcomere length, shorter close to and longer away from the muscle-tendon interface. Once calibrated with a richer data set, our model may help surgeons to prevent muscle overstretch and make informed decisions about optimal stretch increments, stretch timing, and stretch amplitudes. We anticipate our study to open new avenues in orthopedic and reconstructive surgery and enhance

    As healthcare organisations seek to enhance safety and quality in a changing environment, organisational learning practices can help to improve existing skills and knowledge and provide opportunities to discover better ways of working together. Leadership at executive, middle management, and local levels is needed to create a sense of shared purpose. This shared vision should help to build effective relationships, facilitate connections between action and reflection, and strengthen the desirable elements of the healthcare culture while modifying outdated assumptions, procedures, and structures.

  10. Organisational Pathologies Under Conditions of Economic Downswing

    Directory of Open Access Journals (Sweden)

    Pasieczny Jacek

    2017-06-01

    Full Text Available The topic of organisational pathology is surprisingly absent in literature on management, especially when bearing in mind the theoretical and practical import of such questions. The intention of the author is to fill in this gap, at least partially. The paper is based on an analysis of literature and an empirical research conducted by the author. The research applied partially structured interviews as its method. These interviews were conducted with entrepreneurs and managers of various levels. They made possible the drawing of conclusions relating to conditions behind the genesis and growth of selected organisational pathologies in a situation of economic downswing. The article briefly presents the concept and influence of pathology on the functioning of an organisation. The author concentrates on the causes of the phenomenon and presents them from various perspectives. It is during times of economic downswing that an increase in unethical behaviour, including corruption, mobbing as well as others, becomes particularly visible. Also noticeable is concentrating on limiting costs, which can sometimes reach pathological scale. This can lead to a permanent loss of pro-development potential by the organisation. Moreover, numerous pathological phenomena emerge at the tangent point of the organisation and its surroundings. The source of many undesirable phenomena in the organisation and in its relations with its surroundings is a fall in trust, which makes its appearance in crisis situations. More often than not, managers facing a situation in which they have no choice perpetuate organisational pathologies, whilst, at the same time, being aware of the lack of validity of their actions. However, a more frequent source of problems is the differences in perspective in perceiving organisational phenomena by various actors and stakeholders.

  15. The relationship between organisational communication and perception.

    Science.gov (United States)

    Marynissen, H M F

    2011-01-01

    Both researchers and managers search for the most appropriate form of organisational communication. The aim of such an organisational communication is to influence the receivers' perception to confirm, adapt or change behaviour according to the sender's intention. This paper argues that to influence the receivers' perception, a specific form of communication that is embedded in a specific organisational culture is required. It also demands prior knowledge of the existing organisational schemata and the current perception concerning the topic that has to be communicated. The rationale is that three obstacles hinder the objectives of traditional communication strategies to influence perception according to the sender's objectives. The first challenge is that a receiver of a certain message never garners one single, clearly pronounced message conveyed by one single person. Yet, few studies are based on multiple messages from various sources. This makes most of the communication strategies in use obsolete. The second strain is the dual mode of thinking that forms organisational members' perceptions: the heuristic and the cogitative (Taleb, 2010). Most organisational communication theories are based on the paradigm in which receivers of information process this information in a rational way, while research in the field of neurobiology (Lehrer, 2009) indicates that rationality is dominated by emotions. The third difficulty is that organisational members constrain to well-established, ingrained schemas (Labianca et al., 2000; Balogun and Johnson, 2004). Based on these existing schemas, the scattered information from multiple sources, and the inability to process that information through cognitive reasoning, organisational members construct perceptions that are not in line with the objectives of the sender's communication. This article reviews different communication theories, points out key concepts in the literature on individual and collective perceptions, and suggests

    Research purpose: The aim of the study was to investigate the relationships amongst psychological meaningfulness, work engagement and organisational commitment and to test for a possible mediation effect of work engagement on the relationship between psychological meaningfulness and organisational commitment. Motivation for the study: Managers have to rethink ways of improving productivity and performance at work, due to the diverse, and in some instances escalating, needs of employees (e.g. financial support to uphold their interest in and enjoyment of working. Research approach, design and method: A quantitative approach was employed to gather the data for the study, utilising a cross-sectional survey design. The sample (n = 415 consisted of working employees from various companies and positions in Gauteng, South Africa. Main findings: The results confirmed a positive relationship between psychological meaningfulness, work engagement and organisational commitment. Further, psychological meaningfulness predicts work engagement, whilst psychological meaningfulness and work engagement predict organisational commitment. Practical/managerial implications: Employers identifying their employees’ commitment patterns and mapping out strategies for enhancing those that are relevant to organisational goals will yield positive work outcomes (e.g. employees who are creative, seek growth or challenges for themselves. Contribution/value-add: This study contributes to the literature through highlighting the impact that meaningful work has on sustaining employee commitment to the organisation.

    Full Text Available The purpose of this study is to identify the correlation between the corporate social responsibility performance and the Organisational Social Capital. Inductively, through grounded theory, this paper uses secondary data to develop a theoretical model which presents the relationship between the following concepts: business codes, stakeholders, Corporate Social Performance (CSP and Organisational Social Capital (OSC. This study brings together two main areas of research, namely: Organisational Social Capital and business ethics. This represents a gap in the literature, to which this research will address. Three propositions are put forward and discussed using secondary data collection methods. The findings suggest that there is a strong correlation between the characteristics which improve the quality of organisation-stakeholders relationship and the effectiveness of implementing business codes and, therefore, the increasing Corporate Social Performance. The proposed ethical framework has, at the same time, a similar effect by incrementing Organisational Social Capital, because it shares similar features with the relation between organisation-stakeholders, business codes and CSP.

The proposed ethical framework has, at the same time, a similar effect by incrementing Organisational Social Capital, because it shares similar features with the relation between organisation-stakeholders, business codes and CSP.

    Full Text Available Those organisations which do not change according to environmental pressures, suffer from organisational inertia. The purpose of this study is to explore the manifestation of organisational inertia in the target organisation. The target population for this study was a group of trainees, representing the geographic and demographic levels of a particular state department. In South Africa, surveys of this nature were only executed in the corporate sector. The results indicate that organisational inertia is a phenomenon that affects both corporate and governmental organisations. Opsomming Organisasies wat nie ooreenkomstig omgewingsdruk verander nie, ly aan organisasietraagheid. Die doel van die studie is om organisasietraagheid te konseptualiseer en die manifestasie daarvan in die teikenorganisasie te ondersoek. Die teikenpopulasie bestaan uit ’n groep kursusgangers wat die demografiese en geografiese samestelling van ‘n tipiese staatsdepartement verteenwoordig. In Suid -Afrika is navorsing van hierdie aard nog net in die korporatiewe sektor uitgevoer. Die resultate toon aan dat organisasietraagheid ‘n faktor is wat beide die korporatiewe omgewing en staatsorganisasies beïnvloed.

    Full Text Available The vast research on organisational justice has focused on the organisation and the supervisor. This study aims to further this line of research by integrating two trends within organisational justice research: the overall approach to justice perceptions and the multifoci perspective of justice judgments. Specifically, this study aims to explore the effects of two additional sources of justice, coworker-focused justice and customer-focused justice, on relevant employees’ outcomes—burnout, turnover intentions, job satisfaction, and workplace deviance— while controlling the effect of organisation-focused justice and supervisor-focused justice. Given the increased importance attributed to coworkers and customers, we expect coworker-focused justice and customer-focused justice to explain incremental variance in the measured outcomes, above and beyond the effects of organisation-focused justice and supervisor-focused justice. Participants will be university students from Austria and Germany employed by service organisations. Data analysis will be conducted using structural equation modeling.

    Since different types of stretching exercises may alter athletic performance, we compared the effects of three types of stretching exercises on badminton jump smash. Sixteen male collegiate badminton players performed one of three different stretching exercises in a counterbalanced order on different days. Static stretching had seven typical stretches, while dynamic stretching involved nine dynamic movements, and resistance dynamic stretching was performed with weighted vests and dumbbells. Before and after each stretching exercise, subjects performed 20 trials of jump smashes. Dependent measurements were the jump heights during jump smashes, velocities of jump-smashed shuttlecocks, and drop point of jump-smashed shuttlecocks. To test the effects of each stretching exercise, we performed mixed model ANOVAs and calculated between-time effect sizes (ES). Each stretching exercise improved the jump heights during jump smashes (type main effect: F(2,75)=1.19, P=0.31; static stretching: 22.1%, Pjump-smashed shuttlecocks (type main effect: F(2,75)=2.18, P=0.12; static stretching: 5.7%, P=0.61, ES=0.39; dynamic stretching: 3.4%, P=0.94, ES=0.28; resistance dynamic stretching: 6%, P=0.50, ES=0.66). However, there were no differences among the stretching exercises for any measurement. The drop point of jump-smashed shuttlecocks did not change (interaction: F(2,75)=0.88, P=0.42). All stretching exercises improved badminton jump smash performance, but we could not determine the best protocol. Since badminton requires high-speed movement and explosive force, we suggest performing dynamic stretching or resistance dynamic stretching.

  7. The Effect of Static Stretch on Elastin Degradation in Arteries

    2013-01-01

    Previously we have shown that gradual changes in the structure of elastin during an elastase treatment can lead to important transition stages in the mechanical behavior of arteries [1]. However, in vivo arteries are constantly being loaded due to systolic and diastolic pressures and so understanding the effects of loading on the enzymatic degradation of elastin in arteries is important. With biaxial tensile testing, we measured the mechanical behavior of porcine thoracic aortas digested with a mild solution of purified elastase (5 U/mL) in the presence of a static stretch. Arterial mechanical properties and biochemical composition were analyzed to assess the effects of mechanical stretch on elastin degradation. As elastin is being removed, the dimensions of the artery increase by more than 20% in both the longitude and circumference directions. Elastin assays indicate a faster rate of degradation when stretch was present during the digestion. A simple exponential decay fitting confirms the time constant for digestion with stretch (0.11±0.04 h−1) is almost twice that of digestion without stretch (0.069±0.028 h−1). The transition from J-shaped to S-shaped stress vs. strain behavior in the longitudinal direction generally occurs when elastin content is reduced by about 60%. Multiphoton image analysis confirms the removal/fragmentation of elastin and also shows that the collagen fibers are closely intertwined with the elastin lamellae in the medial layer. After removal of elastin, the collagen fibers are no longer constrained and become disordered. Release of amorphous elastin during the fragmentation of the lamellae layers is observed and provides insights into the process of elastin degradation. Overall this study reveals several interesting microstructural changes in the extracellular matrix that could explain the resulting mechanical behavior of arteries with elastin degradation.

    2006-01-01

    In a recent paper (J. Bredenbeck, J. Helbing, J.R. Kumita, G.A. Woolley, P. Hamm, α-helix formation in a photoswitchable peptide tracked from picoseconds to microseconds by time resolved IR spectroscopy, Proc. Natl. Acad. Sci USA 102 (2005) 2379), we have investigated the folding of a photo-switchable α-helix with a kinetics that could be fit by a stretched exponential function exp(-(t/τ) β ). The stretching factor β became smaller as the temperature was lowered, a result which has been interpreted in terms of activated diffusion on a rugged energy surface. In the present paper, we discuss under which conditions diffusion problems occur with stretched exponential kinetics (β 1). We show that diffusion problems do have a strong tendency to yield stretched exponential kinetics, yet, that there are conditions (strong perturbation from equilibrium, performing the experiment in the folding direction) under which compressed exponential kinetics would be expected instead. We discuss the kinetics on free energy surfaces predicted by simple initiation-propagation models (zipper models) of α-helix folding, as well as by folding funnel models. We show that our recent experiment has been performed under condition for which models with strong downhill driving force, such as the zipper model, would predict compressed, rather than stretched exponential kinetics, in disagreement with the experimental observation. We therefore propose that the free energy surface along a reaction coordinate that governs the folding kinetics must be relatively flat and has a shape similar to a 1D golf course. We discuss how this conclusion can be unified with the thermodynamically well established zipper model by introducing an additional kinetic reaction coordinate

    Highlights: → Endothelin-1 expression by adult rat astrocytes correlates with cell proliferation. → Stretch-induced ET-1 is inhibited by GsMtx-4, a specific inhibitor of Ca 2+ permeant SACs. → The less specific SAC inhibitor streptomycin also inhibits ET-1 secretion. → Stretch-induced ET-1 production depends on a calcium influx. → SAC pharmacology may provide a new class of therapeutic agents for CNS pathology. -- Abstract: The expression of endothelins (ETs) and ET-receptors is often upregulated in brain pathology. ET-1, a potent vasoconstrictor, also inhibits the expression of astrocyte glutamate transporters and is mitogenic for astrocytes, glioma cells, neurons, and brain capillary endothelia. We have previously shown that mechanical stress stimulates ET-1 production by adult rat astrocytes. We now show in adult astrocytes that ET-1 production is driven by calcium influx through stretch-activated ion channels (SACs) and the ET-1 production correlates with cell proliferation. Mechanical stimulation using biaxial stretch ( 2+ threshold. This coupling of mechanical stress to the astrocyte endothelin system through SACs has treatment implications, since all pathology deforms the surrounding parenchyma.

    2014-01-01

    This book addresses human and organisational factors which are present at different moments of the lifetime of an at-risk installation (from design to dismantling). At-risk organisations are considered as firstly human systems, and the objective is then to highlight individual and collective mechanisms in these organisations. Several questions are addressed, notably the origins of at-risk behaviour, and the reasons of the repetition of errors by these organisations. A first chapter, while referring to examples, addresses the human dimension of safety: human and organisational factors as obstacles, normal accidents (Three Mile Island), accidents in high-reliability organisations (Chernobyl), identification of root causes (Tokai-mura), and social-technical approach to safety (Fukushima). By also referring to examples, the second chapter addresses how to analyse at-risk organisations: individual behaviours (case of naval and air transport accidents), team coordination (a fire, the Challenger accident), and organisational regulation (organisations forms and routines, explosion of BP Texas City, explosion of Columbia)

    To identify relationships among variables affecting nurses' performance and productivity, namely professional attitudes, organisational culture, organisational justice and exposure to mobbing. The determination of the factors affecting performance and productivity is important for providing efficient nursing services. These factors have been investigated in the literature independently, but the relationship among them has not been clearly identified. This cross-sectional questionnaire study included 772 nurses working in a University Hospital accredited by Joint Commission International. The professional attitude score of the nurses was high (4.35 ± 0.63). However, their organisational justice (2.22 ± 1.26) and organisational culture (2.47 ± 0.71) scores were low. Nurses were subjected to mobbing at a high level (0.82 ± 0.78). As the organisational justice increased, the organisational culture increased and the mobbing decreased. As the organisation culture decreased, the mobbing increased. There was a positive correlation between organisation culture and organisational justice of the nurses and a negative correlation with mobbing. The results of the study are essential for improving nurses' performance and productivity. © 2016 John Wiley & Sons Ltd.

    Patient safety has been high on the agenda for more than a decade. Despite many national initiatives aimed at improving patient safety, the challenge remains to find coherent and sustainable organisation-wide safety-improvement programmes. In the UK, the Safer Patients' Initiative (SPI) was established to address this challenge. Important in the success of such an endeavour is understanding 'readiness' at the organisational level, identifying the preconditions for success in this type of programme. This article reports on a case study of the four NHS organisations participating in the first phase of SPI, examining the perceptions of organisational readiness and the relationship of these factors with impact by those actively involved in the initiative. A mixed-methods design was used, involving a survey and semistructured interviews with senior executive leads, the principal SPI programme coordinator and the four operational leads in each of the SPI clinical work areas in all four organisations taking part in the first phase of SPI. This preliminary work would suggest that prior to the start of organisation-wide quality- and safety-improvement programmes, organisations would benefit from an assessment of readiness with time spent in the preparation of the organisational infrastructure, processes and culture. Furthermore, a better understanding of the preconditions that mark an organisation as ready for improvement work would allow policymakers to set realistic expectations about the outcomes of safety campaigns.

    Full Text Available Abstract Background Plantar heel pain is a commonly occurring foot complaint. Stretching is frequently utilised as a treatment, yet a systematic review focusing only on its effectiveness has not been published. This review aimed to assess the effectiveness of stretching on pain and function in people with plantar heel pain. Methods Medline, EMBASE, CINAHL, AMED, and The Cochrane Library were searched from inception to July 2010. Studies fulfilling the inclusion criteria were independently assessed, and their quality evaluated using the modified PEDro scale. Results Six studies including 365 symptomatic participants were included. Two compared stretching with a control, one study compared stretching to an alternative intervention, one study compared stretching to both alternative and control interventions, and two compared different stretching techniques and durations. Quality rating on the modified Pedro scale varied from two to eight out of a maximum of ten points. The methodologies and interventions varied significantly between studies, making meta-analysis inappropriate. Most participants improved over the course of the studies, but when stretching was compared to alternative or control interventions, the changes only reached statistical significance in one study that used a combination of calf muscle stretches and plantar fascia stretches in their stretching programme. Another study comparing different stretching techniques, showed a statistically significant reduction in some aspects of pain in favour of plantar fascia stretching over calf stretches in the short term. Conclusions There were too few studies to assess whether stretching is effective compared to control or other interventions, for either pain or function. However, there is some evidence that plantar fascia stretching may be more effective than Achilles tendon stretching alone in the short-term. Appropriately powered randomised controlled trials, utilizing validated outcome

    2016-10-01

    Full Text Available Background: Innovation is recognised as one of the most important determinant of organisational performance. Yet, the results of studies that investigate the relationship between innovation and organisational performance are inconclusive. The inconsistency has been attributed to a number of factors, which include, among others, the measures used to evaluate organisational performance. Aim: This study was set out to identify, categorise and critically analyse the instruments used to assess organisational performance when investigating the relationship between innovation and organisational performance. Setting: The study focuses on all scientific publications reporting on organisational performance, inclusive of both financial and non-financial indicators of performance, and are not limited to any specific country or industry. Methods: The systematic literature review methodology was used to identify studies which investigated the relationship between innovation and organisational performance. Once identified, articles were analysed on the way organisational performance was measured. Classification was done with reference to financial and non-financial indicators, accounting and market-based, as well as objective and subjective measures. Results: The findings show that profitability, sales growth and return on assets (ROA are the most preferred accounting-based financial measures of organisation performance. In addition, Tobin’s Q was found to be the most favoured market-based financial measure of organisational performance. The study further reveals that market share, customer satisfaction and productivity are the most popular non-financial-based measures of organisational performance. Conclusion: The use of measures of organisational performance is often left to the discussion of the researcher, which is not implicitly wrong, but does little to contribute to the body of knowledge on this important topic. Researchers are firstly urged to

    2016-01-01

    Inter-organisational communication failures during times of real-world disasters impede the collaborative response of agencies responsible for ensuring the public's health and safety. In the best of circumstances, communications across jurisdictional boundaries are ineffective. In times of crisis, when communities are grappling with the impact of a disaster, communications become critically important and more complex. Important factors for improving inter-organisational communications are critical thinking and problem-solving skills; inter-organisational relationships; as well as strategic, tactical and operational communications. Improving communication, critical thinking, problem-solving and decision-making requires a review of leadership skills. This discussion begins with an analysis of the existing disaster management research and moves to an examination of the importance of inter-organisational working relationships. Before a successful resolution of a disaster by multiple levels of first responders, the group of organisations must have a foundation of trust, collegiality, flexibility, expertise, openness, relational networking and effective communications. Leaders must also be prepared to improve leadership skills through continual development in each of these foundational areas.

    This study was undertaken to examine the role of interset stretching on the time course of acceleration portion AP and mean velocity profile during the concentric phase of 2 bench-press sets with a submaximal load (60% of the 1 repetition maximum). Twenty-five college students carried out, in 3 different days, 2 consecutive bench-press sets leading to failure, performing between sets static stretching, ballistic stretching, or no stretching. Acceleration portion and lifting velocity patterns of the concentric phase were not altered during the second set, regardless of the stretching treatment performed. However, when velocity was expressed in absolute terms, static stretching reduced significantly (p velocity during the second set compared to the first one. Therefore, if maintenance of a high absolute velocity over consecutive sets is important for training-related adaptations, static stretching should be avoided or replaced by ballistic stretching.

  3. Strategic Orientation and Organisational Culture in Polish Public Organisations: Insights from the Miles and Snow Typology

    Directory of Open Access Journals (Sweden)

    Wronka-Pośpiech Martyna

    2016-05-01

    Full Text Available Polish public organisations are often perceived as having strong bureaucratic orientation, avoiding both change and risk. However, in the last decade a distinct change in the management model of public organisations can be noticed. Public sector becomes an open ground for mergers and partnerships, entrepreneurial leadership, diversified services and commercialization (Golensky and DeRuiter 1999; Zimmerman and Dart, 1998; Pollitt and Bouckaert, 2004; Walker, 2013]. Public organisations embrace these strategies from the for-profit sector in order to manage change and to be effective. Most importantly, public organisations are adopting these frameworks in order to survive the changing operating environment, including changes in the level of government funding. Our paper draws on the Miles and Snow (1978 typology of generic strategies - prospectors, defenders, analysers, and reactors - to identify different organisational strategies within public organisations providing social services in Poland. In order to assess organisational culture we used the most widespread and used in many empirical studies Cameron and Quinn’s model (2003, the Competing Values Framework (CVF, from which four cultures - adhocracy, clan, market and hierarchy - emerge. The choice of these two providers of social services was dictated by our conviction, that these organisations are critical both for the national economy and for mitigating, counteracting and preventing social exclusion.

    2011-07-01

    Full Text Available Contrast Stretching is an important part in medical image processing applications. Contrast is the difference between two adjacent pixels. Fuzzy statistical values are analyzed and better results are produced in the spatial domain of the input image. The histogram mapping produces the resultant image with less impulsive noise and smooth nature. The probabilities of gray values are generated and the fuzzy set is determined from the position of the input image pixel. The result indicates the good performance of the proposed fuzzy based stretching. The inverse transform of the real values are mapped with the input image to generate the fuzzy statistics. This approach gives a flexible image enhancement for medical images in the presence of noises.

    1990-01-01

    An economical assessment of Angra 1 fuel cycle stretch-out is performed by means of NUCOST 1.0, a PWR power cost calculation code. International basic costs and an interest rate of 10%a were utilized. During the natural part of the fuel cycle an hypothetical capacity factor of 70% and in the stretch-out part a decrease in Plant's thermal efficiency have also been taken into account. The neutronic data were generated by FASER, MULTIMEDIUM, MEDIUM and PINPOW code system, simulating Angra 1 in the CAOC (constant Axial-Offset Control) operation. Assumming no proplems in the Plant's strecth-out phase, an optimum extension pont of 1 MWd/kg would be attained, what affords an US$700,000 savings by cycle when fuel and operation and maintenance costs are considered.

  7. Anomalies in the coil-stretch transition of flexible polymers

    Ghosal, Aishani; Cherayil, Binny J.

    2018-03-01

    The flow-induced coil-stretch transition of high molecular weight polymers has generally been held to be of first order. But evidence of significant slowing down in the rate at which the polymers relax to equilibrium in the vicinity of the transition suggests that the thermodynamic character of the transition may be less clear-cut. The above slowing down effect is actually characteristic of a second-order transition, and it points to the existence of a broad spectrum of conformational states in the transition region, analogous to the existence of fluctuations of all length scales at a critical point. In this paper, using a path integral approach based on a free-draining finitely extensible chain model, we calculate various polymer properties as a function of elongational flow as a way of exploring different statistical mechanical details of the coil-stretch transition. These properties include the molecular weight dependence of the flow-extension curve of the polymer, the distribution of its steady-state end-to-end distances, and the characteristic relaxation time τR of these distances. Among other findings, our calculations indicate that the coil-stretch transition is discontinuous in the N → ∞ limit, that the effective free energy of the chain is unimodal at all values of the flow, becoming broad and flat in the immediate vicinity of the transition, and that the ratio of τR to the Rouse relaxation time increases abruptly at the transition before eventually reaching a plateau value at large flow strengths. These aspects of the coil-stretch transition place it among a larger class of unconventional nominally first-order single chain transitions that include the adsorption transition of surface-tethered polymers and the escape transition of compressed polymers.

    Head, D. A.; Rodgers, G. J.

    1999-02-01

    We introduce a model for granular surface flow which exhibits both stretched exponential and power law avalanching over its parameter range. Two modes of transport are incorporated, a rolling layer consisting of individual particles and the overdamped, sliding motion of particle clusters. The crossover in behaviour observed in experiments on piles of rice is attributed to a change in the dominant mode of transport. We predict that power law avalanching will be observed whenever surface flow is dominated by clustered motion.

    The mechanical performance of materials reinforced by cellulose nanofibrils is highly affected by the orientation of these fibrils. This paper investigates the nanofibril orientation distribution of films of partly oriented cellulose nanofibrils. Stripes of hydrogel films were subjected to different amount of strain and, after drying, examined with X-ray diffraction to obtain the orientation of the nanofibrils in the films, caused by the stretching. The cellulose nanofibrils had initially a random in-plane orientation in the hydrogel films and the strain was applied to the films before the nanofibrils bond tightly together, which occurs during drying. The stretching resulted in a reorientation of the nanofibrils in the films, with monotonically increasing orientation towards the load direction with increasing strain. Estimation of nanofibril reorientation by X-ray diffraction enables quantitative comparison of the stretch-induced orientation ability of different cellulose nanofibril systems. The reorientation of nanofibrils as a consequence of an applied strain is also predicted by a geometrical model of deformation of nanofibril hydrogels. Conversely, in high-strain cold-drawing of wet cellulose nanofibril materials, the enhanced orientation is promoted by slipping of the effectively stiff fibrils

    A new method is developed for representing the magnetospheric field B as a distorted dipole field. Because delxB = 0 must be maintained,such a distortion may be viewed as a transformation of the vector potential A. The simplest form is a one-dimensional ''stretch transformation'' along the x axis, a generalization of a method introduced by Voigt. The transformation is concisely represented by the ''stretch function'' f(x), which is also a convenient tool for representing features of the substorm cycle. Onedimensional stretch transformations are extended to spherical, cylindrical, and parabolic coordinates and then to arbitrary coordinates. It is next shown that distortion transformations can be viewed as mappings of field lines from one pattern to another: Euler potentials are used in the derivation, but the final result only requires knowledge of the field and not of the potentials. General transformations in Cartesian and arbitrary coordinates are then derived,and applications to field modeling, field line motion, MHD modeling, and incompressible fluid dynamics are considered. copyrightAmerican Geophysical Union 1987

  13. Longitudinal Stretching for Maturation of Vascular Tissues Using Magnetic Forces

    Full Text Available Cellular spheroids were studied to determine their use as “bioinks” in the biofabrication of tissue engineered constructs. Specifically, magnetic forces were used to mediate the cyclic longitudinal stretching of tissues composed of Janus magnetic cellular spheroids (JMCSs, as part of a post-processing method for enhancing the deposition and mechanical properties of an extracellular matrix (ECM. The purpose was to accelerate the conventional tissue maturation process via novel post-processing techniques that accelerate the functional, structural, and mechanical mimicking of native tissues. The results of a forty-day study of JMCSs indicated an expression of collagen I, collagen IV, elastin, and fibronectin, which are important vascular ECM proteins. Most notably, the subsequent exposure of fused tissue sheets composed of JMCSs to magnetic forces did not hinder the production of these key proteins. Quantitative results demonstrate that cyclic longitudinal stretching of the tissue sheets mediated by these magnetic forces increased the Young’s modulus and induced collagen fiber alignment over a seven day period, when compared to statically conditioned controls. Specifically, the elastin and collagen content of these dynamically-conditioned sheets were 35- and three-fold greater, respectively, at seven days compared to the statically-conditioned controls at three days. These findings indicate the potential of using magnetic forces in tissue maturation, specifically through the cyclic longitudinal stretching of tissues.

  14. Stretching Diagnostics and Mixing Properties In The Stratosphere

    Science.gov (United States)

    Legras, B.; Shuckburgh, E.

    The "finite size Lyapunov exponent" and the "effective diffusivity" are two diagnos- tics of mixing which have been recently introduced to investigate atmospheric flows. Both have been used to successfully identify the barriers to transport, for instance at the edge of the stratospheric polar vortex. Here we compare the two diagnostics in detail. The equivalent length has the advantage of arising as a mixing quantification from a rigid theoretical framework, however it has the disadvantage of being an aver- age quantity (the average around a tracer contour). The finite size Lyapunov exponent may be defined at any point in the flow, and quantifies the stretching properties expe- rienced by a fluid parcel both in its past and future evolution. In particular, the lines of maximum stretching at any time delineate the building blocks of the chaotic stirring. However the interpretation of the finite size Lyapunov exponent as a mixing time is less direct and depends on the alignment of tracer contours with the stretching lines.

  15. A Novel Stretch Sensor to Measure Venous Hemodynamics

    Directory of Open Access Journals (Sweden)

    2018-07-01

    Full Text Available Chronic venous insufficiency is a debilitating condition causing varicose veins and venous ulcers. The pathophysiology includes reflux and venous obstruction. The diagnosis is often made by clinical examination and confirmed by Venous Doppler studies. Plethysmography helps to quantitatively examine the reflux and diagnose the burden of deep venous pathology to better understand venous hemodynamics, which is not elicited by venous duplex examination alone. However, most of these tests are qualitative, expensive, and not easily available. In this paper, we demonstrate the potential use of a novel stretch sensor in the assessment of venous hemodynamics during different maneuvers by measuring the change in calf circumference. We designed the stretch sensor by using semiconductor strain gauges pasted onto a small metal bar to form a load cell. The elastic and Velcro material attached to the load cell form a belt. It converts the change in limb circumference to a proportional tension (force of distension when placed around the calf muscle. We recorded the change in limb circumference from arrays of stretch sensors by using an in-house data acquisition system. We calculated the venous volume (VV, venous filling index (VFI, ejection fraction (EF and residual venous volume (RVV on two normal subjects and on two patients to assess venous hemodynamics. The values (VV > 60 ml, VFI 60%, RVV 2ml/s, EF 35% in patients were comparable to those reported in the literature.

    The report presents an overview of Emergency Preparedness Organisations (EPO) in Sweden, Finland and Norway and presentations of insights from a study of the staff positions' work instructions in the command centre in an emergency situation. The results indicate potential for improvement in several areas. A number of the improvements are related to introduction of new technology and they should be seen in connection with ensuring safe and reliable communication lines and power supply. Analysis of the data identified four main categories where further studies could contribute to improvement: 1) Communication and exchange of information. 2) Tools and technology. 3) Staffing and organisation. 4) Procedures. The usefulness of the Man Technology and Organisation method in analysing the emergency management decision-making process within the authorities was considered as an interesting issue for continuation of the project. The interface between utility and authorities was pointed out as an important area for continuation. (Author)

  17. Organisational socialisation in a crisis context.

    Science.gov (United States)

    Lalonde, Carole

    2010-04-01

    The objective of this paper is to highlight the dimensions characterising the socialisation process in a crisis context. Based on the definition of organisational socialisation advanced by Van Maanen and Schein (1979) and employed later by Jones (1986), a crisis is presented as a passage from a 'normal' situation to an 'exceptional' situation. A crisis represents a socialisation context in the sense that it is a novel state in which actors must develop a different way of mobilising their knowledge, utilising their skills, and practicing their trade or profession. The paper discusses certain findings that have emerged from the literature on organisational socialisation, as well as from the testimony of actors who participated in efforts to manage the Quebec ice-storm crisis of early 1998. It is hoped that this exploratory study's data will give rise to fruitful interaction between the field of organisational socialisation and that of crisis management.

    This study examined the association between five-factor model personality traits and perceptions of organisational justice. The sample for the study comprised 903 participants (35-50 years old; 523 women) studied in 2007 and 2012. Measures used were the Neuroticism, Extraversion, Openness, Five-Factor Inventory questionnaire and the short organisational justice measure. The results showed that high neuroticism was associated with low distributive, procedural and interactional justice. Furthermore, high agreeableness was associated with high procedural and interactional justice and high openness with high distributive justice. This study suggests that neuroticism, agreeableness and openness are involved in perceptions of organisational justice and that personality should be considered in research and in practices at the workplace. © 2018 International Union of Psychological Science.

    Effective collaboration has always been one of the foundations of CERN's success. An essential ingredient for collaboration is communication and a new body EIROFORUM has just held its first meeting in Brussels with the aim of developing greater cross fertilization of ideas and projects. Seven organisations, CERN, EMBL (molecular biology), ESA (space activities), ESO (astronomy and astrophysics), ESRF (synchrotron radiation), ILL (neutron source) and EFDA (fusion) are currently members of EIROFORUM. Common interest between the organisations in computational grid development, materials science, instrumentation, public outreach and technology transfer has made EIROFRUM an essential group for maximising these European research organisations' resources. Increasing involvement in the Sixth Framework Programme, Europe's research guidelines for the next four years, is also one of the goals of the group. CERN takes over the chair of EIROFORUM in July 2001 and the next meeting will be held on site on 24 October .

    Full Text Available The implementation of lean manufacturing is one of the main tools for attaining a higher performance level in the Romanian organisations. The study uses data collected at middle management level from organisations located in Transylvania. The organisations come from different fields of activity and are in different stages of lean implementation. The article makes use of quantitative and qualitative instruments for the evaluation of lean in the above mentioned companies. Characteristics as waste reduction, cost, quality, product design have different approaches in the companies. Their way of approach gives useful information regarding the type of company from the point of view of lean manufacturing implementation. This knowledge provides a useful support at different managerial levels in the process of decision making.

  4. Carbon footprinting. An introduction for organisations

    International Nuclear Information System (INIS)

    2007-08-01

    To some degree or other, every person and every organisation, either directly or indirectly, is responsible for producing carbon dioxide gas which finds its way into the atmosphere and therefore contributes to the greenhouse effect. The amount of carbon dioxide produced by a person, an organisation, a company, an industry, an event, or even a population can be quantified in what is now described as a carbon footprint. Gases other than carbon dioxide are also released to the atmosphere through man's activities and these can also be evaluated in terms of the carbon footprint. This document explains the meaning of the expression 'carbon footprint' and aims to assist businesses and organisations to determine collective and individual carbon footprints

  7. Information in organisations: directions for information management

    Directory of Open Access Journals (Sweden)

    Joyce Kirk

    1999-01-01

    Full Text Available The work of managers in small and medium-sized enterprises is very information-intensive and the environment in which it is done is very information rich. But are managers able to exploit the wealth of information which surrounds them? And how can information be managed in organisations so that its potential for improving business performance and enhancing the competitiveness of these enterprises can be realised? Answers to these questions lie in clarifying the context of the practice of information management by exploring aspects of organisations and managerial work and in exploring the nature of information at the level of the organisation and the individual manager. From these answers it is possible to suggest some guidelines for managing the integration of business strategy and information, the adoption of a broadly-based definition of information and the development of information capabilities.

    2013-01-01

    Full Text Available Due to negative demographic trends that primarily took hold of rural areas in the Republic of Serbia as early as at the end of the twentieth century - a decline in birth-rate and migrations from rural to urban areas, the question of ever growing number of combined classes and their organisation is being raised. Combined classes in schools do not represent a desirable model that should be aspired to in the organising of educational work in primary education. In fact it is a necessity and practical need in certain social rural areas. Combined classes are increasingly becoming a reality. Village schools make 60 percent of the total number of schools and are attended by only 8 percent of pupils. The larger number of grades a classroom teacher works with in a classroom, the more numerous teaching organisation problems there are. The Educational Strategy of the Republic of Serbia 2011-2120 says that small village schools should be saved since their number will increase in the coming years considering demographic trends. This paper depicts main didactic problems that occur in the process of simultaneous work with students of different ages, in the same room, by one class teacher, as well as the possibility of their solution. Methods used in this paper include theoretical analysis of the existing literature as well as conversations with primary school teachers who teach combined classes.

  9. Developing organisational ethics in palliative care.

    Palliative carers constantly face ethical problems. There is lack of organised support for the carers to handle these ethical problems in a consistent way. Within organisational ethics, we find models for moral deliberation and for developing organisational culture; however, they are not combined in a structured way to support carers' everyday work. The aim of this study was to describe ethical problems faced by palliative carers and develop an adapted organisational set of values to support the handling of these problems. Ethical problems were mapped out using focus groups and content analysis. The organisational culture were developed using normative analysis and focus group methodology within a participatory action research approach. Main participants and research context: A total of 15 registered nurses and 10 assistant nurses at a palliative unit (with 19 patient beds) at a major University Hospital in Sweden. Ethical considerations: The study followed standard ethics guidelines concerning informed consent and confidentiality. We found six categories of ethical problems (with the main focus on problems relating to the patient's loved ones) and five categories of organisational obstacles. Based on these findings, we developed a set of values in three levels: a general level, an explanatory level and a level of action strategies. The ethical problems found corresponded to problems in other studies with a notable exception, the large focus on patient loved ones. The three-level set of values is a way to handle risks of formulating abstract values not providing guidance in concrete care voiced in other studies. Developing a three-level set of values adapted to the specific ethical problems in a concrete care setting is a first step towards a better handling of ethical problems.

    Weise, Louis D; Panfilov, Alexander V

    2013-01-01

    We introduce an electromechanical model for human cardiac tissue which couples a biophysical model of cardiac excitation (Tusscher, Noble, Noble, Panfilov, 2006) and tension development (adjusted Niederer, Hunter, Smith, 2006 model) with a discrete elastic mass-lattice model. The equations for the excitation processes are solved with a finite difference approach, and the equations of the mass-lattice model are solved using Verlet integration. This allows the coupled problem to be solved with high numerical resolution. Passive mechanical properties of the mass-lattice model are described by a generalized Hooke's law for finite deformations (Seth material). Active mechanical contraction is initiated by changes of the intracellular calcium concentration, which is a variable of the electrical model. Mechanical deformation feeds back on the electrophysiology via stretch-activated ion channels whose conductivity is controlled by the local stretch of the medium. We apply the model to study how stretch-activated currents affect the action potential shape, restitution properties, and dynamics of spiral waves, under constant stretch, and dynamic stretch caused by active mechanical contraction. We find that stretch conditions substantially affect these properties via stretch-activated currents. In constantly stretched medium, we observe a substantial decrease in conduction velocity, and an increase of action potential duration; whereas, with dynamic stretch, action potential duration is increased only slightly, and the conduction velocity restitution curve becomes biphasic. Moreover, in constantly stretched medium, we find an increase of the core size and period of a spiral wave, but no change in rotation dynamics; in contrast, in the dynamically stretching medium, we observe spiral drift. Our results may be important to understand how altered stretch conditions affect the heart's functioning.

    The paper deals with the abandonment of offshore wells. Decommissioning of offshore installations is a complex multi-disciplined issue, which raises a number of technical, organisational and environmental challenges. The success of a planned decommissioning operation depends on the development of a clear understanding of the complex blend of drivers which control the decommissioning process and their inter-relationship. Due to the complexity of the inter-relationship between the primary drivers one cannot separate the technological, organisational and environmental issues raised by the decommissioning of offshore installations. The optimal solution will be a compromise between all the decommissioning drivers mentioned in this paper. 5 figs., 3 tabs.

    Mannion and Davies’ article recognises whistleblowing as an important means of identifying quality and safety issues in healthcare organisations. While ‘voice’ is a useful lens through which to examine whistleblowing, it also obscures a shifting pattern of uncertain ‘truths.’ By contextualising cultures which support or impede whislteblowing at an organisational level, two issues are overlooked; the power of wider institutional interests to silence those who might raise the alarm and changing ideas about what constitutes adequate care. A broader contextualisation of whistleblowing might illuminate further facets of this multi-dimensional problem. PMID:27239870

    2014-01-01

    In the field of business continuity management, organisations commit sums of money (often very large sums) to develop and maintain their continuity capability. Despite this, there is almost no measurement of whether this expense offers value for money, or whether it is targeted in the right areas. This paper will explain some methods of measuring components of a business continuity programme. The important outputs from this measurement activity are to demonstrate that an organisation's continuity capability is improving over time, and to identify areas of weakness that should be targeted during future work.

    Progress in health care integration is largely linked to changes in processes and ways of doing. These changes have knowledge management and learning implications. For this reason, the use of the concept of organisational learning is explored in the field of integrated care. There are very limited contributions that have connected the fields of organisational learning and care integration in a systematic way, both at the theoretical and empirical level. For this reason, hybridization of both perspectives still provides opportunities for understanding care integration initiatives from a research perspective as well as potential applications in health care management and planning.

  6. Micropatterning stretched and aligned DNA for sequence-specific nanolithography

    Science.gov (United States)

    Petit, Cecilia Anna Paulette

    Techniques for fabricating nanostructured materials can be categorized as either "top-down" or "bottom-up". Top-down techniques use lithography and contact printing to create patterned surfaces and microfluidic channels that can corral and organize nanoscale structures, such as molecules and nanorods in contrast; bottom-up techniques use self-assembly or molecular recognition to direct the organization of materials. A central goal in nanotechnology is the integration of bottom-up and top-down assembly strategies for materials development, device design; and process integration. With this goal in mind, we have developed strategies that will allow this integration by using DNA as a template for nanofabrication; two top-down approaches allow the placement of these templates, while the bottom-up technique uses the specific sequence of bases to pattern materials along each strand of DNA. Our first top-down approach, termed combing of molecules in microchannels (COMMIC), produces microscopic patterns of stretched and aligned molecules of DNA on surfaces. This process consists of passing an air-water interface over end adsorbed molecules inside microfabricated channels. The geometry of the microchannel directs the placement of the DNA molecules, while the geometry of the airwater interface directs the local orientation and curvature of the molecules. We developed another top-down strategy for creating micropatterns of stretched and aligned DNA using surface chemistry. Because DNA stretching occurs on hydrophobic surfaces, this technique uses photolithography to pattern vinyl-terminated silanes on glass When these surface-, are immersed in DNA solution, molecules adhere preferentially to the silanized areas. This approach has also proven useful in patterning protein for cell adhesion studies. Finally, we describe the use of these stretched and aligned molecules of DNA as templates for the subsequent bottom-up construction of hetero-structures through hybridization

    This study compared the effects of 3 weeks of upper-body vibration training, vibration and stretching, and stretching alone on shoulder flexibility in college-aged men. Twenty-one men were randomly assigned to vibration-stretching (VS; n = 8), vibration only (VO; n = 6), or stretching only (SO; n = 7) groups that trained 3 times per week for 3 weeks. All 3 groups performed 9 total sets of 30-second stretches. The VS group performed four 30-second upper-body vibration exercises and five 30-second upper-body stretching exercises. The VO group performed nine 30-second upper-body vibration exercises. The SO group performed nine 30-second upper-body stretching exercises. Shoulder flexion (SF), shoulder extension (SE), and shoulder transverse extension (STE) were assessed by a Leighton Flexometer and back scratch tests bilaterally (BSR, BSL) were measured via tape measure. A 1-way analysis of variance (ANOVA) evaluated groups at baseline and a 2-way repeated-measures ANOVA evaluated the interventions over time. At baseline, there were no group differences in age, height, or weight. There was a significant (p alone or combined with stretching, is a viable alternative to a standard stretching routine when attempting to increase shoulder flexibility. Adding vibration training to a flexibility regimen may improve the likelihood of regularly performing flexibility sessions because of increased variety.

    Highlights: • Uniaxial stretching activates Ca 2+ signaling in human lung fibroblasts. • Stretch-induced intracellular Ca 2+ elevation is mainly via Ca 2+ influx. • Mechanical strain enhances ATP release from fibroblasts. • Stretch-induced Ca 2+ influx is not mediated by released ATP or actin cytoskeleton. - Abstract: One cause of progressive pulmonary fibrosis is dysregulated wound healing after lung inflammation or damage in patients with idiopathic pulmonary fibrosis and severe acute respiratory distress syndrome. The mechanical forces are considered to regulate pulmonary fibrosis via activation of lung fibroblasts. In this study, the effects of mechanical stretch on the intracellular Ca 2+ concentration ([Ca 2+ ] i ) and ATP release were investigated in primary human lung fibroblasts. Uniaxial stretch (10–30% in strain) was applied to fibroblasts cultured in a silicone chamber coated with type I collagen using a stretching apparatus. Following stretching and subsequent unloading, [Ca 2+ ] i transiently increased in a strain-dependent manner. Hypotonic stress, which causes plasma membrane stretching, also transiently increased the [Ca 2+ ] i . The stretch-induced [Ca 2+ ] i elevation was attenuated in Ca 2+ -free solution. In contrast, the increase of [Ca 2+ ] i by a 20% stretch was not inhibited by the inhibitor of stretch-activated channels GsMTx-4, Gd 3+ , ruthenium red, or cytochalasin D. Cyclic stretching induced significant ATP releases from fibroblasts. However, the stretch-induced [Ca 2+ ] i elevation was not inhibited by ATP diphosphohydrolase apyrase or a purinergic receptor antagonist suramin. Taken together, mechanical stretch induces Ca 2+ influx independently of conventional stretch-sensitive ion channels, the actin cytoskeleton, and released ATP

    Full Text Available Organisations have difficulty retaining employees who have the necessary talent, skills and knowledge to give the company a competitive edge in a global market, thus emphasising the need for organisational commitment. The objective of the study was to explore the relationship between corporate social responsibility and organisational commitment within a South African retail organisation. Corporate social responsibility has a positive influence on consumer behaviour and can contribute to corporate success because CSR activities enhance an organisation’s image. Research has indicated that corporate social responsibility is related to an employee’s commitment. The Corporate Social Responsibility Scale and the Organisational Commitment Scale were administered to a non-probability sample of 171 employees from a population of 268 employees in the human resources department of a retail company. Person’s correlation analysis was used to determine the relationship between corporate social responsibility and organisational commitment. This study provided insight into the corporate social responsibility of the organisation. Managers and practitioners in the human resources may use these findings for the development of corporate social responsibility policies and practices in order to build employee commitment

    Full Text Available A necessary condition of effective functioning of human resources management in an organisation is the creation of adequate organisational conditions including the existence of a human resources management department, its size, composition and responsibility, which are formed following particular conditions of the given organisation. Competitive environment of organisations operating in Slovakia and Czech Republic is growing with the process of world economy globalisation, and it brings the need of flexibility in management, and therefore we have to get used to changes also in the sphere of human resources management, and learn to cope with new impulses and situations. At present, that predominantly includes spreading effects of global financial and economic crisis, influencing all spheres of life in Slovakia and in Czech Republic too. Handling this situation presupposes flexibility in assessment of changes in environment where organisations operate, ability to detect all positive as well as negative impacts and situations, and formulation of measures to enhance their own position sensibly and cautiously. Due to the need of focusing of organisations on comprehensive arrangement of human resources management, in questionnaire researches, we focused on finding out whether and to what extent organisations operating in Slovakia (n = 340 and in Czech Republic (n = 109 focus on human resources management arrangement. The objective of the article is to compare results in the sphere of human resources in organisations operating in Slovak and Czech Republics. The results show that 67% organisations in Slovakia and only 43% in the Czech Republic had a human resources management department which realised followed human resources management functions and personnel strategy.

    Few studies have assessed regional variation in the organisation of stroke services, particularly health care resourcing, presence of protocols and discharge planning. Our aim was to compare stroke care organisation within middle- (MIC) and high-income country (HIC) hospitals participating in the Head Position in Stroke Trial (HeadPoST). HeadPoST is an on-going international multicenter crossover cluster-randomized trial of 'sitting-up' versus 'lying-flat' head positioning in acute stroke. As part of the start-up phase, one stroke care organisation questionnaire was completed at each hospital. The World Bank gross national income per capita criteria were used for classification. 94 hospitals from 9 countries completed the questionnaire, 51 corresponding to MIC and 43 to HIC. Most participating hospitals had a dedicated stroke care unit/ward, with access to diagnostic services and expert stroke physicians, and offering intravenous thrombolysis. There was no difference for the presence of a dedicated multidisciplinary stroke team, although greater access to a broad spectrum of rehabilitation therapists in HIC compared to MIC hospitals was observed. Significantly more patients arrived within a 4-h window of symptoms onset in HIC hospitals (41 vs. 13%; Porganisation and treatment. Future multilevel analyses aims to determine the influence of specific organisational factors on patient outcomes. Copyright © 2016 Elsevier B.V. All rights reserved.
