There is less geographic variation in the commitment rate of juvenile offenders than is commonly assumed. Apparently, judges across the country develop a similar standard of what percentage of youths they face should be committed. This standard may be similar across the country because it represents broadly shared ideals. However, there is much…

Are "part-time" general practitioners workforce idlers or committed professionals?

Dwan, Kathryn M; Douglas, Kirsty A; Forrest, Laura E

2014-09-19

The traditional view of general practice holds that only general practitioners (GPs) in full-time clinical practice can provide quality patient care. Nevertheless, increasing numbers of GPs are choosing to work sessionally, that is, ostensibly "part-time". There are concerns about the health workforce's ability to meet demand and also fears that patient care may be compromised. We sought answers to a) what activities do GPs undertake when not consulting patients, b) why do they choose to work sessionally, and c) does sessional general practice reflect a lack of commitment to patients and the profession? Semi-structured interviews were conducted with GPs who worked sessionally, (i.e. six or fewer sessions a week in clinical general practice, where a session comprises four consecutive hours of patient care). These data were analysed qualitatively and saturation was reached. The majority of participants were in full-time paid employment, while part-time in clinical general practice. They reported that consultations increasingly required the management of patients with complex, chronic conditions who also required psychological management. Coupled with unrealistic patient expectations, these factors led GPs to be concerned about maintaining the quality patient care they considered professionally desirable. Many diversified their work activities to ensure that they retained their professional standards. "Part-time" general practice is a misnomer that masks the contribution these GPs make as part of the health workforce. Sessional practice more accurately describes the nature of our participants' clinical work. Their choice of sessional work is a professional response to the increasing demands within the consultation. It enables GPs to maintain their commitment to quality patient care and their profession, while attenuating the challenges of demanding consultations. Sessional general practitioners demonstrate strong commitment to their patients and the profession.

Part-time work and job sharing in health care: is the NHS a family-friendly employer?

Science.gov (United States)

Branine, Mohamed

2003-01-01

This paper examines the nature and level of flexible employment in the National Health Service (NHS) by investigating the extent to which part-time work and job sharing arrangements are used in the provision and delivery of health care. It attempts to analyse the reasons for an increasing number of part-timers and a very limited number of job sharers in the NHS and to explain the advantages and disadvantages of each pattern of employment. Data collected through the use of questionnaires and interviews from 55 NHS trusts reveal that the use of part-time work is a tradition that seems to fit well with the cost-saving measures imposed on the management of the service but at the same time it has led to increasing employee dissatisfaction, and that job sharing arrangements are suitable for many NHS employees since the majority of them are women with a desire to combine family commitments with career prospects but a very limited number of employees have had the opportunity to job share. Therefore it is concluded that to attract and retain the quality of staff needed to ensure high performance standards in the provision and delivery of health care the NHS should accept the diversity that exists within its workforce and take a more proactive approach to promoting a variety of flexible working practices and family-friendly policies.

Organizational commitment is employees’ strength of bond for the organization which they work for. There should be shared values for mentioned about commitment. If those values are adopted by a large number of people and if they are strong, the level of commitment will increase. The main purpose of this study is to determine  the impact of organizational culture on commitment and the relationship. This study composed of two main parts. The first part consists of theoretical framework which explains organizational culture and commitment’s relationship. The second part is devoted to empirical analysis. Survey study was made in this part which held on 189 employees in the province of İzmir.

Global health governance as shared health governance.

Science.gov (United States)

Ruger, Jennifer Prah

2012-07-01

With the exception of key 'proven successes' in global health, the current regime of global health governance can be understood as transnational and national actors pursuing their own interests under a rational actor model of international cooperation, which fails to provide sufficient justification for an obligation to assist in meeting the health needs of others. An ethical commitment to providing all with the ability to be healthy is required. This article develops select components of an alternative model of shared health governance (SHG), which aims to provide a 'road map,' 'focal points' and 'the glue' among various global health actors to better effectuate cooperation on universal ethical principles for an alternative global health equilibrium. Key features of SHG include public moral norms as shared authoritative standards; ethical commitments, shared goals and role allocation; shared sovereignty and constitutional commitments; legitimacy and accountability; country-level attention to international health relations. A framework of social agreement based on 'overlapping consensus' is contrasted against one based on self-interested political bargaining. A global health constitution delineating duties and obligations of global health actors and a global institute of health and medicine for holding actors responsible are proposed. Indicators for empirical assessment of select SHG principles are described. Global health actors, including states, must work together to correct and avert global health injustices through a framework of SHG based on shared ethical commitments.

Sachs, L

2001-01-01

Offering employment structures other than traditional full-time positions in your practice can help you draw excellent job applicants and also can enable you to increase morale, job satisfaction, and productivity. However, there are many decisions you must make when offering a part-time, flex-time, or job-sharing position. This article explores the pros and cons of offering alternative job structures. It suggests ways to make part-time, flex-time, or job-sharing positions work most effectively, both for the employee and for your practice. In addition, this article suggests which positions are best suited to alternative structures.

2009-01-01

Medical practices are in a complex industry and require the expertise of both physician and business leaders to be successful. Sharing the leadership between these two professionals brings with it challenges that are best met if the environment is supportive. This support comes in the form of external aspects such as selection, role definition, organizational hierarchy, time, and process. Critical to shared leadership is communication, both frequency and quality. Conflicts are likely to occur, and how they are resolved is what determines the strength of a shared governance relationship. Reality is that finding the balance in shared governance is diffcult, but with effort and commitment, it can provide the organization with the performance it hopes to achieve.

Modeling of the time sharing for lecturers

E. Yu. Shakhova

2017-01-01

Full Text Available In the context of modernization of the Russian system of higher education, it is necessary to analyze the working time of the university lecturers, taking into account both basic job functions as the university lecturer, and others.The mathematical problem is presented for the optimal working time planning for the university lecturers. The review of the documents, native and foreign works on the study is made. Simulation conditions, based on analysis of the subject area, are defined. Models of optimal working time sharing of the university lecturers («the second half of the day» are developed and implemented in the system MathCAD. Optimal solutions have been obtained.Three problems have been solved:1 to find the optimal time sharing for «the second half of the day» in a certain position of the university lecturer;2 to find the optimal time sharing for «the second half of the day» for all positions of the university lecturers in view of the established model of the academic load differentiation;3 to find the volume value of the non-standardized part of time work in the department for the academic year, taking into account: the established model of an academic load differentiation, distribution of the Faculty number for the positions and the optimal time sharing «the second half of the day» for the university lecturers of the department.Examples are given of the analysis results. The practical application of the research: the developed models can be used when planning the working time of an individual professor in the preparation of the work plan of the university department for the academic year, as well as to conduct a comprehensive analysis of the administrative decisions in the development of local university regulations.

Expressions of commitment and independence: Exploring men’s emotional responsibility in heterosexual couple relationships

Directory of Open Access Journals (Sweden)

Tove Thagaard

2014-02-01

Full Text Available This paper examines men’s contributions to the division of emotional labour in heterosexual couple relationships by exploring the dimensions of commitment and independence, and how couples deal with challenges. The study is based on individual interviews with each of the partners in ten urban middle-class couples in Norway. The results indicate diversity in middle-class men’s approaches to emotional responsibility, which is expressed through three models. The model of shared responsibility implies that the man’s contributions in the relationship represent expressions of responsive commitment. The man finds a balance between giving priority to his personal interests and considering shared interests; a pattern we refer to as collaborative independence, and he shares the responsibility for coping with challenges with his partner. The model of gendered responsibility implies that the man’s contributions in the relationship are characterized by non-responsive commitment. The man gives priority to his personal interests in a way we refer to as conflicting independence, and refrains from sharing the responsibility for coping with challenges with his partner. Finally, a third model, termed partial responsibility, is also evident in the data. This model is a combination of collaborative independence and non-responsive commitment, and may represent a phase of transition towards collaboration on an equal basis. A discussion of interpretations of the diversity in men’s approaches to commitment and independence concludes the paper.

This report contains the model documentation and user instructions of the FAIR model (Framework to Assess International Regimes for differentiation of commitments). FAIR is an interactive - scanner-type - computer model to quantitatively explore a range of alternative climate policy options for international differentiation of future commitments and link these to targets for global climate protection. The model includes three different approaches for evaluating international commitment regimes: (1) Increasing participation: in this mode the number of parties involved and their level of commitment gradually increase according to participation and differentiation rules, such as per capita income, per capita emissions, or contribution to global warming; (2) Convergence: in this mode all parties participate in the burden-sharing regime, with emission rights converging to equal per capita levels over time; (3) Triptych: different burden sharing rules are applied for different sectors (e.g. convergence of per capita emissions in the domestic sector, efficiency and de-carbonisation targets for the industry sector and the power generation sector). The first two modes are representatives of top-down methodologies, so from global emission ceilings to regional emission budgets, whereas the triptych approach is more bottom-up in character, although it can be combined with specific emission targets (as illustrated in the case of the EU). In order to construct and evaluate global emission profiles, the FAIR model also has the mode: Scenario construction. In this mode the impacts in terms of the main climate indicators can be scanned of a constructed or well-defined global emissions profile

The Role of Minority Stressors in Lesbian Relationship Commitment and Persistence over Time.

Barrantes, Renzo J; Eaton, Asia A; Veldhuis, Cindy B; Hughes, Tonda L

2017-06-01

The Investment Model of relationship commitment uses interpersonal investment, relationship satisfaction, quality of alternatives, and commitment to predict relationship longevity (Rusbult, 1980, 1983). Although ample support for the Investment Model has been found in heterosexual couples, it appears to be less powerful in predicting stability in same-sex relationships (Beals, Impett, & Peplau, 2002), potentially because the model does not account for factors unique to same-sex relationships, such as anti-gay discrimination. However, no research has tested the nature and power of sexual minority stress factors in predicting same-sex relationship stability over time. Using secondary, longitudinal data collected from a diverse sample of lesbian women in relationships ( N = 211), we examined how internalized homonegativity, sexual identity disclosure, and workplace discrimination affected the Investment Model antecedents of relationship persistence: satisfaction, quality of alternatives, and investment. We tested the influence of sexual minority stressors on Investment Model processes using structural equations modeling and found that sexual identity disclosure was positively associated with satisfaction and investment, internalized homonegativity was only negatively associated with satisfaction and investment, while workplace discrimination was negatively associated with alternatives. Moreover, both relationship satisfaction and investment influenced commitment which predicted persistence in these relationships over about seven years' time, demonstrating support for the Investment Model. Our findings support the addition of sexual minority stress variables to the Investment Model when examining same-sex relationships and implications are discussed.

Must developing countries commit quantified targets? Time flexibility and equity in climate change mitigation

International Nuclear Information System (INIS)

Sugiyama, Taishi; Deshun, Liu

2004-01-01

Equity and efficiency dimensions of global time flexibility in GHG emission reduction are analyzed with an integrated assessment model. Global time flexibility is justifiable to some extent as found in previous studies by Wigley et al. Nevertheless, it does not necessarily serve as a rationale to delay emission reduction commitment and efforts of developed countries as they suggested. The time flexibility can be saved for developing countries, and it must be so in equity consideration; early reduction by developed countries eases burden of developing countries in both time and emission quantity dimensions. This equity-oriented argument is robust against time and spatial efficiency consideration, since the apparent benefits that might accrue to developed countries from delaying reductions will by no means be transferred to far distant future developing countries for mitigation of and adaptation to climate change. The analysis thus support entry into force of the Kyoto Protocol without participation of key low income developing countries such as China and India with legally binding quantified targets in the First Commitment Period from 2008 to 2012

Gender and the construction of intimacy among committed couples with children.

Science.gov (United States)

Reynolds, Conroy; Knudson-Martin, Carmen

2015-06-01

This study began with curiosity regarding how long-term couples with children manage their relationships in view of changing societal demands and ideals. Couples interviewed for this study described the intersection of time and intimacy as a core issue. Thus, this analysis focused on how couples construct intimacy in shared time. The diverse sample included 17 heterosexual working and professional class couples in the United States who had been committed for at least 10 years and whose oldest child was aged 6-16. Analysis identified four types of shared time experiences: gender divided, elusive, growing, and emotionally connected. Four factors influenced these types: (a) negotiated gendered differences, (b) intentionality, (c) mutual attending, and (d) dyadic friendship. The most emotionally connected couples reported that time together reinforced satisfaction and pleasure from their relationships. Results help explain different ways couples successfully negotiate changing expectations for heterosexual relationships and why some couples struggle. Findings suggest that therapists help couples intentionally develop habits of friendship and mutual attending. © 2014 Family Process Institute.

Little research exists regarding how real-time continuous glucose monitoring (RT-CGM) data sharing plays a role in the relationship between patients and their care partners. To (1) identify the benefits and challenges related to RT-CGM data sharing from the patient and care partner perspective and (2) to explore the number and type of individuals who share and follow RT-CGM data. This qualitative content analysis was conducted by examining publicly available blogs focused on RT-CGM and data sharing. A thematic analysis of blogs and associated comments was conducted. A systematic appraisal of personal blogs examined 39 blogs with 206 corresponding comments. The results of the study provided insight about the benefits and challenges related to individuals with diabetes sharing their RT-CGM data with a care partner(s). The analysis resulted in three themes: (1) RT-CGM data sharing enhances feelings of safety, (2) the need to communicate boundaries to avoid judgment, and (3) choice about sharing and following RT-CGM data. RT-CGM data sharing occurred within dyads (n = 46), triads (n = 15), and tetrads (n = 2). Adults and children with type 1 diabetes and their care partners are empowered by the ability to share and follow RT-CGM data. Our findings suggest that RT-CGM data sharing between an individual with diabetes and their care partner can complicate relationships. Healthcare providers need to engage patients and care partners in discussions about best practices related to RT-CGM sharing and following to avoid frustrations within the relationship.

Full Text Available Changes in the external environment in the world of education, ranging from the social, economy, technology, and politics, require a rethinking of these influences as an institution and  their interactions. Islamic University has more challenges than other high education. The challenges are linked to the human resource improvement in science and technology. Islamic University has also been bonded to a commitment in leading the core mission of university; therefore, Islamic University has to hold strong commitment and needs to be attached by a self-image which bolds life values in leading the commitment. This research is based on the theory of reasoned action and the theory of planned behavior, which develops other theories related to knowledge-sharing behavior such as covering information technology and Islamic teachings. Data are analyzed using Structural Equation Modeling with Analysis of Moment Structures application program. The research objectives are to test and analyze direct and indirect effects of information technology covering variables, Islamic teachings, attitude, subjective norm and perceived behavior control and knowledge-sharing behavior.The result shows that technology, religion taught, and theory of planned behavior insignificantly influence knowledge-sharing behavior.

From controlled to committed.

Hess, J C

1996-02-01

Most of us agree that people are our most important resource. Yet we spend a minimal amount of time learning more about human behavior, communication, and how our attitudes and behavior impact employee performance. Instead we rely on traditional methods of negative reinforcement in an attempt to control our areas of responsibility. While these methods can render some short-term success, managers and organizations that succeed during these times of change and fierce competition will be those that take the time to understand and capture the power of a committed workforce. The committed workforce is energized, not simply compliant, as a result of having basic human needs for achievement satisfied, belonging to a group, and receiving recognition for its contributions. Committed workers typically describe the manager as one who has the ability to give them a great degree of control over their area of influence. We all know that we don't change our leadership style like we change clothes. Old habits die hard. it takes a personal commitment and lots of practice to rid outselves of habits and behavior that no longer serve our departments and facilities. This commitment, however, is crucial to survival. As managers, we must cope with increasing ambiguity and uncertainty in the workplace. To survive these challenges, we must improve our interpersonal skills and ability to successfully bring out the best in others. I believe that success will continue for managers who not only increase their knowledge and technical ability, but who also inspire their workers to move forward with a collective sense of enthusiasm and purpose.

The purpose of this study is to explore and examine, specific to the restaurant industry, two important constructs emerging from the safety climate literature: employee perceptions of safety training and management commitment to safety. Are these two separate constructs? Are there both individual- and shared group-level safety perceptions for these two constructs? What are the relationships between these two constructs and future injury outcomes? A total of 419 employees from 34 limited-service restaurants participated in a prospective cohort study. Employees' perceptions of management commitment to safety and safety training and demographic variables were collected at the baseline. The survey questions were made available in three languages: English, Spanish, and Portuguese. For the following 12 weeks, participants reported their injury experience and weekly work hours. A multivariate negative binomial generalized estimating equation model with compound symmetry covariance structure was used to assess the association between the rate of self-reported injuries and measures of safety perceptions. Even though results showed that the correlation between employees'perceived safety training and management commitment to safety was high, confirmatory factor analysis of measurement models showed that two separate factors fit the model better than as two dimensions of a single factor. Homogeneity tests showed that there was a shared perception of the factor of management commitment to safety for the restaurant workers but there was no consistent perception among them for the factor of perceived safety training. Both individual employees'perceived management commitment to safety and perceptions of safety training can predict employees' subsequent injuries above and beyond demographic variables. However, there was no significant relationship between future injury and employees' shared perception of management commitment to safety. Further, our results suggest that the

The logic of job-sharing in the provision and delivery of health care.

Science.gov (United States)

Branine, M

1998-01-01

By definition the practice of job-sharing starts from the premiss that there is a full-time job to be shared by those who want to balance their work with other commitments. In a public sector institution, such as the National Health Service (NHS), where most employees are female, it seems logical to believe that a job-sharing policy would be able to promote equal opportunities, to increase employee job satisfaction and to reduce labour costs. Hence, this paper attempts to discuss the advantages and disadvantages of having a job-sharing policy, and to analyse the reasons for the limited number of job-sharers in the NHS despite the apparent benefits of job-sharing to both the employees and the employer. This study was carried out in 15 NHS Trusts in northern England and Scotland, by the use of questionnaires and interviews, and found that most NHS managers did not see the practice of job-sharing as a major cost-saving opportunity or as a working pattern that would enhance employee satisfaction and commitment. They saw job-sharing as just a routine equal opportunities request which did not deserve such managerial attention or long-term strategic thinking. It is argued in this paper that job-sharing is a potentially useful option against a background of demographic and other social and economic changes which require the development and use of long-term strategic policies. Therefore, it is concluded that, in the NHS, there is a need for a more active and creative approach to job-sharing, rather than the reactive and passive approach that has dominated the practice so far.

This study was carried out in 15 NHS Trusts in northern England and Scotland, by the use of questionnaires and interviews, and found that most NHS managers did not see the practice of job-sharing as a major cost-saving opportunity or as a working pattern that would enhance employee satisfaction and commitment. They saw job-sharing as just a routine equal opportunities request which did not deserve such managerial attention or long-term strategic thinking. It is argued in this paper that job-sharing is a potentially useful option against a background of demographic and other social and economic changes which require the development and use of long-term strategic policies. Therefore it is concluded that, in the NHS, there is a need for a more active and creative approach to job-sharing rather than the reactive and passive approach that has dominated the practice so far.

24-Hour Relativistic Bit Commitment.

Bit commitment is a fundamental cryptographic primitive in which a party wishes to commit a secret bit to another party. Perfect security between mistrustful parties is unfortunately impossible to achieve through the asynchronous exchange of classical and quantum messages. Perfect security can nonetheless be achieved if each party splits into two agents exchanging classical information at times and locations satisfying strict relativistic constraints. A relativistic multiround protocol to achieve this was previously proposed and used to implement a 2-millisecond commitment time. Much longer durations were initially thought to be insecure, but recent theoretical progress showed that this is not so. In this Letter, we report on the implementation of a 24-hour bit commitment solely based on timed high-speed optical communication and fast data processing, with all agents located within the city of Geneva. This duration is more than 6 orders of magnitude longer than before, and we argue that it could be extended to one year and allow much more flexibility on the locations of the agents. Our implementation offers a practical and viable solution for use in applications such as digital signatures, secure voting and honesty-preserving auctions.

Timing and Commitment of Environmental Policy, Adoption of New Technology, and Repercussions on R and D

International Nuclear Information System (INIS)

Requate, T.

2005-01-01

We investigate the interplay between environmental policy, incentives to adopt new technology, and repercussions on R and D. We study a model where a monopolistic upstream firm engages in R and D and sells advanced abatement technology to polluting downstream firms. We consider four different timing and commitment regimes of environmental tax and permit policies: ex post taxation (or issuing permits), interim commitment to a tax rate (a quota of permits) after observing R and D success but before adoption, and finally two types of ex antecommitment before R and D activity, one with a unique tax rate (quota of permits), the other one with a menu of tax rates (permit quotas). We study the second best tax and permit policies and rank these with respect to welfare. In particular, we find that commitment to a menu of tax rate dominates all other policy regimes

Universal algorithm of time sharing

Timesharing system algorithm is proposed for the wide class of one- and multiprocessor computer configurations. Dynamical priority is the piece constant function of the channel characteristic and system time quantum. The interactive job quantum has variable length. Characteristic recurrent formula is received. The concept of the background job is introduced. Background job loads processor if high priority jobs are inactive. Background quality function is given on the base of the statistical data received in the timesharing process. Algorithm includes optimal trashing off procedure for the jobs replacements in the memory. Sharing of the system time in proportion to the external priorities is guaranteed for the all active enough computing channels (back-ground too). The fast answer is guaranteed for the interactive jobs, which use small time and memory. The external priority control is saved for the high level scheduler. The experience of the algorithm realization on the BESM-6 computer in JINR is discussed

A simple tool for neuroimaging data sharing

Christian eHaselgrove

2014-05-01

Full Text Available Data sharing is becoming increasingly common, but despite encouragement and facilitation by funding agencies, journals, and some research efforts, most neuroimaging data acquired today is still not shared due to political, financial, social, and technical barriers to sharing data that remain. In particular, technical solutions are few for researchers that are not a part of larger efforts with dedicated sharing infrastructures, and social barriers such as the time commitment required to share can keep data from becoming publicly available.We present a system for sharing neuroimaging data, designed to be simple to use and to provide benefit to the data provider. The system consists of a server at the International Neuroinformatics Coordinating Facility (INCF and user tools for uploading data to the server. The primary design principle for the user tools is ease of use: the user identifies a directory containing DICOM data, provides their INCF Portal authentication, and provides identifiers for the subject and imaging session. The user tool anonymizes the data and sends it to the server. The server then runs quality control routines on the data, and the data and the quality control reports are made public. The user retains control of the data and may change the sharing policy as they need. The result is that in a few minutes of the user’s time, DICOM data can be anonymized and made publicly available, and an initial quality control assessment can be performed on the data. The system is currently functional, and user tools and access to the public image database are available at http://xnat.incf.org/.

Optimal Taxation in a Limited Commitment Economy

2012-01-01

This article studies optimal Ramsey taxation when risk sharing in private insurance markets is imperfect due to limited enforcement. In a limited commitment economy, there are externalities associated with capital and labour because individuals do not take into account that their labour and saving decisions affect aggregate labour and capital supply and wages, and thus the value of autarky. Therefore, a Ramsey government has an additional goal, which is to internalize these externalities of l...

Commit* to change? A call to end the publication of the phrase 'commit* suicide'.

Nielsen, Emma; Padmanathan, Prianka; Knipe, Duleeka

Background. Countering stigma is a fundamental facet of suicide prevention efforts.  Integral to this is the promotion of accurate and sensitive language.  The phrase 'commit* suicide' has prompted marked opposition primarily due to the connotations of immorality and illegality.  Methods. The study investigated the frequency of the use of the wordstem 'commit', in relation to self-harm and suicidal behaviours, in the three leading suicide-specific academic journals between 2000 and 2015.  Results. One third (34%) of articles published since the year 2000 used the word 'commit*' when describing an act of self-harm or suicide. Over half of these articles (57%) used the phrase on more than one occasion, with 6% using it more than 10 times in the same manuscript. The percentage of papers utilising the word 'commit*' has fluctuated over time, but there is a promising downward trend in the use of this phrase from 33% in 2000 to 13% in 2015 ( p suicide. Whilst we call for collective responsibility amongst academics and clinicians, editors hold a unique position in ensuring that outdated, inaccurate and stigma-laden terms are expunged from the scientific literature.

An experiment is described which examined the benefits of distributing the input demands of two tracking tasks as a function of task integrality. Visual and auditory compensatory tracking tasks were utilized. Results indicate that presenting the two tracking signals in two input modalities did not improve time-sharing efficiency. This was attributed to the difficulty insensitivity phenomenon.

Career commitment and job performance of Jordanian nurses.

Mrayyan, Majd T; Al-Faouri, Ibrahim

2008-01-01

Career commitment and job performance are complex phenomena that have received little attention in nursing research. A survey was used to assess nurses' career commitment and job performance, and the relationship between the two concepts. Predictors of nurses' career commitment and job performance were also studied. A convenience sample of 640 Jordanian registered nurses was recruited from 24 teaching, governmental, and private hospitals. Nurses "agreed" on the majority of statements about career commitment, and they reported performing "well" their jobs. Using total scores, nurses were equal in their career commitment but they were different in their job performance; the highest mean was scored for nurses in private hospitals. Using the individual items of subscales, nurses were willing to be involved, on their own time, in projects that would benefit patient care. The correlation of the total scores of nurses' career commitment and job performance revealed the presence of a significant and positive relationship (r = .457). Nurses' job performance, gender, and marital status were the best predictors of nurses' career commitment: they explained 21.8% of variance of nurses' career commitment. Nurses' career commitment, time commitment, marital status, and years of experience in nursing were the best predictors of nurses' job performance: they explained 25.6% of variance of nurses' job performance. The lowest reported means of nurses' job performance require managerial interventions.

Schizophrenia—Time to Commit to Policy Change

2014-01-01

Care and outcomes for people with schizophrenia have improved in recent years, but further progress is needed to help more individuals achieve an independent and fulfilled life. This report sets out the current need, informs policy makers and all relevant stakeholders who influence care quality, and supports their commitment to creating a better future. The authors recommend the following policy actions, based on research evidence, stakeholder consultation, and examples of best practice worldwide. (1) Provide an evidence-based, integrated care package for people with schizophrenia that addresses their mental and physical health needs. (2) Provide support for people with schizophrenia to enter and to remain in their community, and develop mechanisms to help guide them through the complex benefit and employment systems. (3) Provide concrete support, information, and educational programs to families and carers on how to enhance care for an individual living with schizophrenia in a manner that entails minimal disruption to their lives. (4) All stakeholders, including organizations that support people living with schizophrenia, should be consulted to regularly revise, update, and improve policy on the management of schizophrenia. (5) Provide support, which is proportionate to the impact of the disease, for research and development of new treatments. (6) Establish adequately funded, ongoing, and regular awareness-raising campaigns that form an integral part of routine plans of action. Implementation of the above recommendations will require engagement by every stakeholder, but with commitment from all, change can be achieved. PMID:24778411

Three-year-olds' understanding of the consequences of joint commitments.

Directory of Open Access Journals (Sweden)

Maria Gräfenhain

Full Text Available Here we investigate the extent of children's understanding of the joint commitments inherent in joint activities. Three-year-old children either made a joint commitment to assemble a puzzle with a puppet partner, or else the child and puppet each assembled their own puzzle. Afterwards, children who had made the joint commitment were more likely to stop and wait for their partner on their way to fetch something, more likely to spontaneously help their partner when needed, and more likely to take over their partner's role when necessary. There was no clear difference in children's tendency to tattle on their partner's cheating behavior or their tendency to distribute rewards equally at the end. It thus appears that by 3 years of age making a joint commitment to act together with others is beginning to engender in children a "we"-intentionality which holds across at least most of the process of the joint activity until the shared goal is achieved, and which withstands at least some of the perturbations to the joint activity children experience.

Time-Varying Transition Probability Matrix Estimation and Its Application to Brand Share Analysis.

Directory of Open Access Journals (Sweden)

Tomoaki Chiba

Full Text Available In a product market or stock market, different products or stocks compete for the same consumers or purchasers. We propose a method to estimate the time-varying transition matrix of the product share using a multivariate time series of the product share. The method is based on the assumption that each of the observed time series of shares is a stationary distribution of the underlying Markov processes characterized by transition probability matrices. We estimate transition probability matrices for every observation under natural assumptions. We demonstrate, on a real-world dataset of the share of automobiles, that the proposed method can find intrinsic transition of shares. The resulting transition matrices reveal interesting phenomena, for example, the change in flows between TOYOTA group and GM group for the fiscal year where TOYOTA group's sales beat GM's sales, which is a reasonable scenario.

Bit commitment is a fundamental cryptographic primitive in which Bob wishes to commit a secret bit to Alice. Perfectly secure bit commitment between two mistrustful parties is impossible through asynchronous exchange of quantum information. Perfect security is however possible when Alice and Bob split into several agents exchanging classical and quantum information at times and locations suitably chosen to satisfy specific relativistic constraints. Here we report on an implementation of a bit commitment protocol using quantum communication and special relativity. Our protocol is based on [A. Kent, Phys. Rev. Lett. 109, 130501 (2012)] and has the advantage that it is practically feasible with arbitrary large separations between the agents in order to maximize the commitment time. By positioning agents in Geneva and Singapore, we obtain a commitment time of 15 ms. A security analysis considering experimental imperfections and finite statistics is presented.

Research on the energy-saving and revenue sharing strategy of ESCOs under the uncertainty of the value of Energy Performance Contracting Projects

International Nuclear Information System (INIS)

Qian, Dong; Guo, Ju’e

2014-01-01

Under the uncertainty of the value of Energy Performance Contracting Projects (EPCPs), this paper develops a revenue-sharing bargaining model between an Energy Service Company (ESCO) and an Energy-Using Organization (EU). Based on the model the paper analyzes the impacts of energy prices, risk-adjusted discount rates and accidents on the ESCO’s bargaining strategies. The research shows that the greater the probability of adverse circumstances is, the higher is the revenue share (of the EU), and the more disadvantageous is the ESCO’s position in the game. Furthermore, we design a forecast–commitment contract between an ESCO and an EU and analyze the optimal product’s energy savings commitment strategy of the ESCO to cope with uncertain energy savings and contract risk. The research illustrates that by introducing penalties and commitments, the contract can eliminate the impact of the uncertain energy savings on the contract execution to a certain extent; when the EU takes a greater commitment risk, the ESCO is willing to provide a higher commitment, thus enhancing the strategy value of the bilateral relationship and reducing the contract risk. Finally, the policy recommendations about improving shared savings contract standard, third-party energy savings measurement and verification mechanism and arbitration mechanism of EPCs are provided. - Highlights: • We provide a method for determining the revenue-sharing bargaining strategy space in a finite bargaining game of the ESCO. • The increase of the probability of adverse circumstances will increase the revenue share (of the EU). • We design a forecast–commitment contract between an ESCO and an EU. • The forecast–commitment contract can eliminate the impact of the uncertain energy savings on the contract execution to a certain extent. • When the EU takes a greater commitment risk, the ESCO is willing to provide a higher commitment

Milek, Anne; Butler, Emily A; Bodenmann, Guy

2015-12-01

Theoretically, spending time together should be central for couples to build intimacy and should be associated with less relationship stress; however, few empirical studies have examined these links. The present study used 14 days of diary data from 92 women to investigate the interplay between the amount of time they spent with their partner (shared time), intimacy, and daily stress originating inside the relationship (intradyadic stress) on a within- and between-personal level. Multilevel analyses revealed moderation patterns: For example, when women spent more time with their partners than usual on a weekday with low levels of intradyadic stress, they reported higher intimacy. These associations varied substantially between women and were weaker on the weekend or on days with high levels of intradyadic stress. At the between-person level, higher average shared time appeared to buffer the negative association between intradyadic stress and intimacy. Our results suggest that daily fluctuations in intradyadic stress, intimacy, and shared time may have different implications compared with aggregated amounts of those variables. Spending more time together on a weekday with low intimacy might be linked to more intradyadic stress, but aggregated over the long run, spending more time together may provide opportunities for stress resolution and help couples to maintain their intimacy.

A Temporal Analysis of the Relation between Organisational Commitment and Work Motivation

Directory of Open Access Journals (Sweden)

Marylène Gagné

2008-06-01

Full Text Available Meyer, Becker, and Vandenberghe (2004 recently proposed a model linking work motivation to organisational commitment. Two studies tested these links prospectively with employees from a Canadian telecommunications company and from an Italian autoparts company. Self-determination theory provided the framework to measure work motivation, such that measures of external, introjected and identified regulation, and intrinsic motivation were linked to Allen and Meyer's (1990 and to O'Reilly and Chatman's (1986 tripartite models of organisational commitment. We hypothesised that Time 1 motivation would be related to changes in commitment over time, but that Time 1 commitment would not be related to motivational changes over time. Results supported hypotheses for affective and normative commitment, but not for continuance commitment.

[Culture and cultural gaps in work teams: implications for organisational commitment].

Sánchez, José C; Lanero, Ana; Yurrebaso, Amaia; Tejero, Blanca

2007-05-01

Some theoreticians of organisational commitment have proposed that culture is an important determinant of organisational commitment. Nevertheless, very few studies have examined the role that work teams culture (subculture) and their cultural gaps play in commitment. This study is an attempt to overcome this lack. Using a sample of 375 work teams from various public and private organisations, it was found that the results confirmed our proposals. Cultural gaps were negatively related to commitment; the teams subculture was positively related to commitment, and more highly to commitment to values than to commitment to continuing. Contrary to the results of other studies, the demographic variables (age, time on the team, time in the company) were not significant, except that educational level was related to the commitment to continue. The implications of these results are analysed.

Information-sharing tendency on Twitter and time evolution of tweeting

Kwon, H. W.; Kim, H. S.; Lee, K.; Choi, M. Y.

2013-03-01

While topics on Twitter may be categorized according to their predictability and sustainability, some topics have characteristics depending on the time scale. Here we propose a good measure for the transition of sustainability, which we call the information-sharing tendency, and find that the unpredictability on Twitter is provoked by the exposure of Twitter users to external environments, e.g., mass media and other social network services. In addition, it is demonstrated that the numbers of articles and comments on on-line newspapers serve as plausible measures of exposure. From such measures of exposure, the time evolution of tweeting can be described, when the information-sharing tendency is known.

Transcriptional regulation of lineage commitment--a stochastic model of cell fate decisions.

Directory of Open Access Journals (Sweden)

Jose Teles

Full Text Available Molecular mechanisms employed by individual multipotent cells at the point of lineage commitment remain largely uncharacterized. Current paradigms span from instructive to noise-driven mechanisms. Of considerable interest is also whether commitment involves a limited set of genes or the entire transcriptional program, and to what extent gene expression configures multiple trajectories into commitment. Importantly, the transient nature of the commitment transition confounds the experimental capture of committing cells. We develop a computational framework that simulates stochastic commitment events, and affords mechanistic exploration of the fate transition. We use a combined modeling approach guided by gene expression classifier methods that infers a time-series of stochastic commitment events from experimental growth characteristics and gene expression profiling of individual hematopoietic cells captured immediately before and after commitment. We define putative regulators of commitment and probabilistic rules of transition through machine learning methods, and employ clustering and correlation analyses to interrogate gene regulatory interactions in multipotent cells. Against this background, we develop a Monte Carlo time-series stochastic model of transcription where the parameters governing promoter status, mRNA production and mRNA decay in multipotent cells are fitted to experimental static gene expression distributions. Monte Carlo time is converted to physical time using cell culture kinetic data. Probability of commitment in time is a function of gene expression as defined by a logistic regression model obtained from experimental single-cell expression data. Our approach should be applicable to similar differentiating systems where single cell data is available. Within our system, we identify robust model solutions for the multipotent population within physiologically reasonable values and explore model predictions with regard to

Time-resolved echo-shared parallel MRA of the lung: observer preference study of image quality in comparison with non-echo-shared sequences

Fink, C.; Puderbach, M.; Zaporozhan, J.; Plathow, C.; Kauczor, H.-U.; Ley, S.

2005-01-01

The aim of this study was to evaluate the image quality of time-resolved echo-shared parallel MRA of the lung. The pulmonary vasculature of nine patients (seven females, two males; median age: 44 years) with pulmonary disease was examined using a time-resolved MRA sequence combining echo sharing with parallel imaging (time-resolved echo-shared angiography technique, or TREAT). The sharpness of the vessel borders, conspicuousness of peripheral lung vessels, artifact level, and overall image quality of TREAT was assessed independently by four readers in a side-by-side comparison with non-echo-shared time-resolved parallel MRA data (pMRA) previously acquired in the same patients. Furthermore, the SNR of pulmonary arteries (PA) and veins (PV) achieved with both pulse sequences was compared. The mean voxel size of TREAT MRA was decreased by 24% compared with the non-echo-shared MRA. Regarding the sharpness of the vessel borders, conspicuousness of peripheral lung vessels, and overall image quality the TREAT sequence was rated superior in 75-76% of all cases. If the TREAT images were preferred over the pMRA images, the advantage was rated as major in 61-71% of all cases. The level of artifacts was not increased with the TREAT sequence. The mean interobserver agreement for all categories ranged between fair (artifact level) and good (overall image quality). The maximum SNR of TREAT did not differ from non-echo-shared parallel MRA (PA: TREAT: 273±45; pMRA: 280±71; PV: TREAT: 273±33; pMRA: 258±62). TREAT achieves a higher spatial resolution than non-echo-shared parallel MRA which is also perceived as an improved image quality. (orig.)

Changes in commitment to change among leaders in home help services.

Westerberg, Kristina; Tafvelin, Susanne

2015-07-06

The purpose of the this study was to explore the development of commitment to change among leaders in the home help services during organizational change and to study this development in relation to workload and stress. During organizational change initiatives, commitment to change among leaders is important to ensure the implementation of the change. However, little is known of development of commitment of change over time. The study used a qualitative design with semi-structured interviews with ten leaders by the time an organizational change initiative was launched and follow-up one year later. Thematic content analysis was used to analyze the interviews. Commitment to change is not static, but seems to develop over time and during organizational change. At the first interview, leaders had a varied pattern reflecting different dimensions of commitment to change. One year later, the differences between leaders' commitment to change was less obvious. Differences in commitment to change had no apparent relationship with workload or stress. The data were collected from one organization, and the number of participants were small which could affect the results on workload and stress in relation to commitment to change. It is important to support leaders during organizational change initiatives to maintain their commitment. One way to accomplish this is to use management team meetings to monitor how leaders perceive their situation. Qualitative, longitudinal and leader studies on commitment to change are all unusual, and taken together, this study shows new aspects of commitment.

Commitment Without Marriage

Science.gov (United States)

Reczek, Corinne; Elliott, Sinikka; Umberson, Debra

2011-01-01

The majority of Americans will marry in their lifetimes, and for many, marriage symbolizes the transition into long-term commitment. However, many Americans cannot legally marry. This article analyzes in-depth interviews with gays and lesbians in long-term partnerships to examine union formation and commitment-making histories. Using a life course perspective that emphasizes historical and biographical contexts, the authors examine how couples conceptualize and form committed relationships despite being denied the right to marry. Although previous studies suggest that commitment ceremonies are a way to form same-sex unions, this study finds that because of their unique social, historical, and biographical relationship to marriage and ceremonies, long-term same-sex couples do not follow normative commitment-making trajectories. Instead, relationships can transition more ambiguously to committed formations without marriage, public ceremony, clear-cut act, or decision. Such an understanding of commitment making outside of marriage has implications for theorizing alternative forms of union making. PMID:21814298

First, we investigate in what ways commitments to these four sets of values are correlated to trust and solidarity at the individual level and, then, whether the belief that others share one’s values is correlated to these aspects of social cohesion for individuals committed...... for a number of socio-economic factors and ideology (on a left-right scale). Finally, individuals who believe that others share their values do not, in general, have higher levels of trust and solidarity. Rather, this belief works in different ways when associated with different sets of community values....

Human embryonic stem cells (hESCs) share an identical genome with lineage-committed cells, yet possess the remarkable properties of self-renewal and pluripotency. The diverse cellular properties in different cells have been attributed to their distinct epigenomes, but how much epigenomes differ remains unclear. Here, we report that epigenomic landscapes in hESCs and lineage-committed cells are drastically different. By comparing the chromatin-modification profiles and DNA methylomes in hESCs and primary fibroblasts, we find that nearly one-third of the genome differs in chromatin structure. Most changes arise from dramatic redistributions of repressive H3K9me3 and H3K27me3 marks, which form blocks that significantly expand in fibroblasts. A large number of potential regulatory sequences also exhibit a high degree of dynamics in chromatin modifications and DNA methylation. Additionally, we observe novel, context-dependent relationships between DNA methylation and chromatin modifications. Our results provide new insights into epigenetic mechanisms underlying properties of pluripotency and cell fate commitment.

PARTICULARITIES OF ORGANIZATIONAL COMMITMENT IN THE SPECIFIC CULTURE OF THE ROMANIAN COMPANIES

Directory of Open Access Journals (Sweden)

Oprea-Valentin BUȘU

2017-08-01

Full Text Available Organizational culture and organizational commitment represent two of the most important concepts to be considered în an well-functioning organization, having a direct influence over employees` lives in that company. Organizational culture, a scientific concept appeared in the field literature at the end of 1980`, in an increasingly unstable business environment, could be defined as a defined series of collective attitudes, ideas, beliefs, symbols and meanings, values and ideologies, rules and norms, feelings or behaviors, as a model and structure of stable practices shared by all the members of that organization and which, by being implemented, come to merge with the structure of organization and its control systems, with the purpose of producing behavioral norms, this way keeping  the unit of organization. In the same time, organizational commitment represents the feeling of membership, of belonging felt by the employee toward the company he/she works in, reflecting the degree to which those characteristics and organizational perspectives are internalized and adopted in his behavior by the subject. Commitment could be also seen as a model of thinking of an employee taking into consideration the level to which personal values and goals are congruent with those of the company. On the other hand, behavioral commitment refers to the process of one employee becoming committed or even stacked into the organization and the way he manage the situation. Our motivation for choosing the theme of this research lays on one hand in the desire to understand the construct of organizational culture and the organizational development, field which I`m interested in,  and on the other hand because the lack of similar research regarding the Romanian companies. The research We have made revealed that there are many studies linking the two concepts with the organizational development in companies from other countries, but only two studies realized in our country

Commit* to change? A call to end the publication of the phrase ‘commit* suicide’

Science.gov (United States)

Nielsen, Emma; Padmanathan, Prianka; Knipe, Duleeka

2016-01-01

Background. Countering stigma is a fundamental facet of suicide prevention efforts.  Integral to this is the promotion of accurate and sensitive language.  The phrase ‘commit* suicide’ has prompted marked opposition primarily due to the connotations of immorality and illegality.  Methods. The study investigated the frequency of the use of the wordstem ‘commit’, in relation to self-harm and suicidal behaviours, in the three leading suicide-specific academic journals between 2000 and 2015.  Results. One third (34%) of articles published since the year 2000 used the word ‘commit*’ when describing an act of self-harm or suicide. Over half of these articles (57%) used the phrase on more than one occasion, with 6% using it more than 10 times in the same manuscript. The percentage of papers utilising the word ‘commit*’ has fluctuated over time, but there is a promising downward trend in the use of this phrase from 33% in 2000 to 13% in 2015 ( p suicide. Whilst we call for collective responsibility amongst academics and clinicians, editors hold a unique position in ensuring that outdated, inaccurate and stigma-laden terms are expunged from the scientific literature.

2017-08-01

Teleoperation could be used in space on-orbit serving missions, such as object deorbits, spacecraft approaches, and automatic rendezvous and docking back-up systems. Teleoperation rendezvous and docking in lunar orbit may encounter bottlenecks for the inherent time delay in the communication link and the limited measurement accuracy of sensors. Moreover, human intervention is unsuitable in view of the partial communication coverage problem. To solve these problems, a shared control strategy for teleoperation rendezvous and docking is detailed. The control authority in lunar orbital maneuvers that involves two spacecraft as rendezvous and docking in the final phase was discussed in this paper. The predictive display model based on the relative dynamic equations is established to overcome the influence of the large time delay in communication link. We discuss and attempt to prove via consistent, ground-based simulations the relative merits of fully autonomous control mode (i.e., onboard computer-based), fully manual control (i.e., human-driven at the ground station) and shared control mode. The simulation experiments were conducted on the nine-degrees-of-freedom teleoperation rendezvous and docking simulation platform. Simulation results indicated that the shared control methods can overcome the influence of time delay effects. In addition, the docking success probability of shared control method was enhanced compared with automatic and manual modes.

Beninson, D.

1977-01-01

The concepts of collective dose and collective dose commitment are discussed, particularly regarding their use to compare the relative importance of the exposure from several radiation sources and to predict future annual doses from a continuing practice. The collective dose commitment contributions from occupational exposure and population exposure due to the different components of the nuclear power fuel cycle are evaluated. A special discussion is devoted to exposures delivered over a very long time by released radionuclides of long half-lives and to the use of the incomplete collective dose commitment. The maximum future annual ''per caput'' doses from present and projected nuclear power programmes are estimated

How do different types of community commitment influence brand commitment? The mediation of brand attachment.

Science.gov (United States)

Zhang, Ning; Zhou, Zhi-min; Su, Chen-ting; Zhou, Nan

2013-11-01

Although previous research indicates that participation in a brand community may foster consumer loyalty to the brand in question, research has seldom examined the mediating effect of community commitment on brand commitment. Drawing from the typologies of organizational commitment, we divide community commitment into three components: continuance community commitment (continuance CC), affective community commitment (affective CC), and normative community commitment (normative CC). We then assess the mediating role of brand attachment in the relationship between these three components and brand commitment. We test the hypotheses using a sample of online mobile phone brand communities in China. The empirical results reveal that brand attachment exerts an indirect (but not mediated) effect on the relationship between continuance CC and brand commitment and on the relationship between normative CC and brand commitment. We also find that it exerts a partial mediating effect on the relationship between affective CC and brand commitment. The findings contribute to the branding literature and have important implications for brand community management.

1999-10-01

This study surveys pregnant women to examine the individual and organizational factors related with organizational commitment, planned timing of maternity leaves and return to work after childbirth. The survey was conducted on 86 pregnant women; among them, 73% were White, 8% were Asian, 7% were African-American, 6% were Hispanic, and 1% were Native-American respondents. The findings revealed that women whose organizations offered guaranteed jobs after childbirth planned to work later into their pregnancies and to return to work sooner after childbirth. Also, women who perceived supportive work-family cultures were more committed to their organizations and planned to return more quickly after childbirth than women who perceived less supportive cultures. Furthermore, women with less traditional attitudes towards parenting planned to work later into their pregnancies and return to work sooner after childbirth.

Psychological reality and the role of the teacher in early-education sharing time

Science.gov (United States)

Alsafi, Abdullah T.

1994-01-01

The study of children's language development has been strongly influenced since the 1950s by linguistic research. How well, however, has the education of young children incorporated the concept of psychological reality, which interrelates the child's perceptual and cognitive development with linguistic and non-linguistic events in his/her environment? In reply to this question, the paper concentrates on"sharing time", known also as"show and tell", which has both affective and cognitive value. Although sharing time is a student-centered activity, the teacher plays a pivotal role in establishing its context, structure and norms. Feedback from the teacher and peers promotes language development, and the growth of curiosity and inquisitiveness. The article is derived from experience in teaching kindergarten teachers to conduct sharing time periods in Saudi Arabia. Practical suggestions are made for the implementation of the activity, in the interests of encouraging spontaneous and personalized language rather than focusing on evaluation of students' competence in the formal aspects of language development.

Griffin, Brooke; Vest, Kathleen; Pohl, Shaunte; Mazan, Jennifer; Winkler, Susan

2014-04-17

Part-time and job-share policies may allow pharmacy practice faculty members to achieve work/life balance while pursuing their professional goals. Precedent for alternative work schedules within the health professions community can be found throughout the literature; however, little is known about part-time roles in academic pharmacy. The design and implementation of 3 different alternative faculty appointments are described and department chair and faculty perspectives are shared. Teaching, service, and scholarship responsibilities, as well as outcomes before and after changes in appointment, are described. Advantages and disadvantages, including advice for other colleges of pharmacy, are presented. Alternate appointments may be a key factor in retaining highly qualified faculty members who continue to bring their expertise to teaching, precepting, and scholarship within a college or school of pharmacy.

Policy Uncertainty, Investment and Commitment Periods

Energy Technology Data Exchange (ETDEWEB)

NONE

2007-07-01

Today's investment decisions in key sectors such as energy, forestry or transport have significant impacts on the levels of greenhouse gas (GHG) emissions over the coming decades. Given the economic and environmental long-term implications of capital investment and retirement, a climate mitigation regime should aim to encourage capital investment in climate-friendly technologies. Many factors affect technology choice and the timing of investment, including investor expectations about future prices and policies. Recent international discussions have focused on the importance of providing more certainty about future climate policy stringency. The design of commitment periods can play a role in creating this environment. This paper assesses how the length of commitment periods influences policy uncertainty and investment decisions. In particular, the paper analyses the relationship between commitment period length and near term investment decisions in climate friendly technology.

Advance market commitments for vaccines against neglected diseases: estimating costs and effectiveness.

Science.gov (United States)

Berndt, Ernst R; Glennerster, Rachel; Kremer, Michael R; Lee, Jean; Levine, Ruth; Weizsäcker, Georg; Williams, Heidi

2007-05-01

The G8 is considering committing to purchase vaccines against diseases concentrated in low-income countries (if and when desirable vaccines are developed) as a way to spur research and development on vaccines for these diseases. Under such an 'advance market commitment,' one or more sponsors would commit to a minimum price to be paid per person immunized for an eligible product, up to a certain number of individuals immunized. For additional purchases, the price would eventually drop to close to marginal cost. If no suitable product were developed, no payments would be made. We estimate the offer size which would make revenues similar to the revenues realized from investments in typical existing commercial pharmaceutical products, as well as the degree to which various model contracts and assumptions would affect the cost-effectiveness of such a commitment. We make adjustments for lower marketing costs under an advance market commitment and the risk that a developer may have to share the market with subsequent developers. We also show how this second risk could be reduced, and money saved, by introducing a superiority clause to a commitment. Under conservative assumptions, we document that a commitment comparable in value to sales earned by the average of a sample of recently launched commercial products (adjusted for lower marketing costs) would be a highly cost-effective way to address HIV/AIDS, malaria, and tuberculosis. Sensitivity analyses suggest most characteristics of a hypothetical vaccine would have little effect on the cost-effectiveness, but that the duration of protection conferred by a vaccine strongly affects potential cost-effectiveness. Readers can conduct their own sensitivity analyses employing a web-based spreadsheet tool. Copyright (c) 2006 John Wiley & Sons, Ltd.

Assessing Knowledge Sharing Among Academics: A Validation of the Knowledge Sharing Behavior Scale (KSBS).

Science.gov (United States)

Ramayah, T; Yeap, Jasmine A L; Ignatius, Joshua

2014-04-01

There is a belief that academics tend to hold on tightly to their knowledge and intellectual resources. However, not much effort has been put into the creation of a valid and reliable instrument to measure knowledge sharing behavior among the academics. To apply and validate the Knowledge Sharing Behavior Scale (KSBS) as a measure of knowledge sharing behavior within the academic community. Respondents (N = 447) were academics from arts and science streams in 10 local, public universities in Malaysia. Data were collected using the 28-item KSBS that assessed four dimensions of knowledge sharing behavior namely written contributions, organizational communications, personal interactions, and communities of practice. The exploratory factor analysis showed that the items loaded on the dimension constructs that they were supposed to represent, thus proving construct validity. A within-factor analysis revealed that each set of items representing their intended dimension loaded on only one construct, therefore establishing convergent validity. All four dimensions were not perfectly correlated with each other or organizational citizenship behavior, thereby proving discriminant validity. However, all four dimensions correlated with organizational commitment, thus confirming predictive validity. Furthermore, all four factors correlated with both tacit and explicit sharing, which confirmed their concurrent validity. All measures also possessed sufficient reliability (α > .70). The KSBS is a valid and reliable instrument that can be used to formally assess the types of knowledge artifacts residing among academics and the degree of knowledge sharing in relation to those artifacts. © The Author(s) 2014.

2017-11-01

Eradication of poliovirus from endemic countries relies on vaccination of children with oral polio vaccine (OPV) many times a year until the age of 5 years. We aimed to determine caregivers' commitment to OPV in districts of Afghanistan at high risk for polio transmission and to examine what knowledge, attitudes, or experiences could threaten commitment. We designed and analysed a poll using face-to-face interviews among caregivers of children under 5 years of age. The sample was drawn via a stratified multistage cluster design with random route household selection. We calculated the percentage of committed and uncommitted caregivers. All percentages were weighted. We then compared percentages of uncommitted caregivers among those with varying knowledge, attitudes, and experiences, using logistic regression to control for possible demographic confounders. Between Dec 19, 2014, and Jan 5, 2015, we interviewed 1980 caregivers, 21% of whom were "uncommitted" to accepting OPV. Multiple measures of knowledge, attitudes, and experiences are associated with lack of commitment. For example, compared with their relevant counterparts, caregivers are more likely to be uncommitted if they did not trust vaccinators "a great deal" (54% vs 9%), if they do not know that polio spreads through contaminated water (41% vs 14%), or if they believe rumours that OPV is not halal (50% vs 21%). To enhance OPV commitment, it might be useful to consider a multifactorial approach that highlights building trust in vaccinators, providing facts about transmission, sharing positive messages to overcome key rumours, and strengthening community support for vaccination.

Competition with Variety Seeking and Habitual Consumption: Price Commitment or Quality Commitment?

Directory of Open Access Journals (Sweden)

Liyang Xiong

2017-01-01

Full Text Available This paper investigates price and quality competition in a market where consumers seek variety and habit formation. Variety seeking is modeled as a decrease in the willingness to pay for product purchased on the previous occasion while habitual consumption may increase future marginal utility. We compare two competing strategies: price commitment and quality commitment. With a three-stage Hotelling-type model, we show that variety seeking intensifies while habitual consumption softens the competition. With price commitment, firms supply lower quality levels in period 1 and higher quality levels in period 2, while, with quality commitment, firms charge higher prices in period 1 and lower prices in period 2. However, the habitual consumption brings the opposite effect. In addition, with quality commitment variety seeking leads to a lower profit and a higher consumer surplus, while habitual consumption leads to the opposite results. On the other side, with price commitment these behaviors have no effect on the consumer surplus, although they still lower down the firm profits. Finally, we also identify conditions under which one strategy outperforms the other.

Synchronization resources in heterogeneous environments: Time-sharing, real-time and Java

International Nuclear Information System (INIS)

Pereira, A.; Vega, J.; Pacios, L.; Sanchez, E.; Portas, A.

2006-01-01

The asynchronous event distribution system (AEDS) was built to provide synchronization resources within the TJ-II local area network. It is a software system developed to add 'soft synchronization' capabilities to the TJ-II data acquisition, control and analysis environments. 'Soft synchronization' signifies that AEDS is not a real-time system. In fact, AEDS is based on TCP/IP over ETHERNET networks. However, its response time is adequate for practical purposes when synchronization requirements can support some delay between event dispatch and message reception. Event broadcasters (or synchronization servers in AEDS terminology) are Windows computers. Destination computers (or synchronization clients) were also Windows machines in the first version of AEDS. However, this fact imposed a very important limitation on synchronization capabilities. To overcome this situation, synchronization clients for different environments have been added to AEDS: for time-sharing operating systems (Unix and Linux), real-time operating systems (OS-9 and VxWorks) and Java applications. These environments have different synchronization primitives, requiring different approaches to provide the required uniform functionality. This has been achieved with POSIX thread library synchronization primitives (mutex and condition variables) on Unix/Linux systems, IPC mechanisms for concurrent processes on OS-9 and VxWorks real-time operating systems, and 'synchronized-wait/notify' primitives on Java virtual machines

Bevers, K; Nauta, S; Stuyt, P M

2004-02-14

Due to various factors such as social changes, an increasing number of couples with two incomes, and a growing proportion of female doctors, there has been a growing demand for part-time work in recent years. This is also true for resident physicians. Objections such as a discontinuity in care and the decline in the quality of education frequently prevent resident physicians from working part-time. Over the past two years, the University Medical Centre Nijmegen, the Netherlands, has experimented with job-sharing on clinical wards for resident physicians in internal medicine. This approach works well in practice, as long as a number of conditions, including the proper transfer of medical information and good communication, are satisfied. Job-sharing is one means of satisfying the growing demand for part-time work among resident physicians and specialists.

Exercisers' identities and exercise dependence: the mediating effect of exercise commitment.

2012-10-01

The purpose of this study was to examine the associations of exercise identity, exercise commitment, exercise dependence, and, particularly, the mediating effects of exercise commitment on the relationship between exercise identity and exercise dependence. 253 Taiwanese regular exercisers completed measures, including the Exercise Dependence Scale-Revised, the Exercise Identity Scale, the Exercise Commitment Scale, and the Godin Leisure Time Exercise Questionnaire. Results showed that exercise identity, exercise dependence, and two types of exercise commitment were moderately to highly correlated. Furthermore, structural equation modelling indicated that a "have to" commitment partially mediated the relationship between exercise identity and exercise dependence. Based on the mediating role of a "have to" commitment, the findings are particularly informative to exercise instructors and for exercise program managers.

However, at the same time, independent directors commonly engage in numerous outside activities potentially reducing their time and commitment with the particular firm. Using Tobin's Q as an approximation of market valuation and controlling for endogeneity, our empirical analysis reveals that neither is independence positively related to firm performance nor are outside activities negatively related t...

as the commitment protocol by Garay \\emph{et al.} from Eurocrypt 2014. A main technical improvement over the scheme mentioned above, and other schemes based on using error correcting codes for UC commitment, we develop a new technique which allows to based the extraction property on erasure decoding as opposed...... to error correction. This allows to use a code with significantly smaller minimal distance and allows to use codes without efficient decoding. Our scheme only relies on standard assumptions. Specifically we require a pseudorandom number generator, a linear error correcting code and an ideal oblivious......, we manage to add the additive homo- morphic property, while at the same time reducing the constants. In fact, when opening a large enough batch of commitments we achieve an amor- tized communication complexity converging to the length of the message committed to, i.e., we achieve close to rate 1...

The general purpose of this work is to analyze the overlap between organizational identification and commitment. Specifically, our study focuses on the analysis of the differences and similarities between sense of belonging (a dimension of organizational identification) and affective commitment (a dimension of organizational commitment). In order to do this, we analyzed their discriminant validity and raised their relationship with variables that previous research had showed like precedent and subsequent variables of them: value congruence, perceived support, organizational citizenship behavior, and intention to continue in the organization. A total of 292 people at one organization completed surveys measuring the variables previously described. The results showed that sense of belonging and affective commitment are different concepts and they have different relationships with relation to precedent and subsequent variables. Affective commitment seems to be more useful than sense of belonging to predict organizational citizenship behavior aimed at the organization and intention to continue. Some practical implications are described.

The asynchronous event distribution system (AEDS) was built to provide synchronization resources within the TJ-II local area network. It is a software system developed to add 'soft synchronization' capabilities to the TJ-II data acquisition, control and analysis environments. 'Soft synchronization' signifies that AEDS is not a real-time system. In fact, AEDS is based on TCP/IP over ETHERNET networks. However, its response time is adequate for practical purposes when synchronization requirements can support some delay between event dispatch and message reception. Event broadcasters (or synchronization servers in AEDS terminology) are Windows computers. Destination computers (or synchronization clients) were also Windows machines in the first version of AEDS. However, this fact imposed a very important limitation on synchronization capabilities. To overcome this situation, synchronization clients for different environments have been added to AEDS: for time-sharing operating systems (Unix and Linux), real-time operating systems (OS-9 and VxWorks) and Java applications. These environments have different synchronization primitives, requiring different approaches to provide the required uniform functionality. This has been achieved with POSIX thread library synchronization primitives (mutex and condition variables) on Unix/Linux systems, IPC mechanisms for concurrent processes on OS-9 and VxWorks real-time operating systems, and 'synchronized-wait/notify' primitives on Java virtual machines.

To examine the impact of financial incentives on physician goal commitment to guideline-recommended hypertension care. Clinic-level cluster-randomized trial with 4 arms: individual, group, or combined incentives, and control. A total of 83 full-time primary care physicians at 12 Veterans Affairs medical centers completed web-based surveys measuring their goal commitment to guideline-recommended hypertension care every 4 months and telephone interviews at months 8 and 16. Intervention arm participants received performance-based incentives every 4 months for 5 periods. All participants received guideline education at baseline and audit and feedback every 4 months. Physician goal commitment did not vary over time or across arms. Participants reported patient nonadherence was a perceived barrier and consistent follow-up was a perceived facilitator to successful hypertension care, suggesting that providers may perceive hypertension management as more of a patient responsibility (external locus of control). Financial incentives may constitute an insufficiently strong intervention to influence goal commitment when providers attribute performance to external forces beyond their control.

Huang, Meiju; Chen, Mei-Yen

2013-08-01

Associations among internal marketing, customer orientation, and organizational commitment were examined, particularly with regard to the moderating effects of work status on the relationships between internal marketing and customer orientation or organizational commitment, in a cross-sectional design with structural equation modeling. Two studies (Ns = 119 and 251) were conducted among full- and part-time service employees at Taipei Sports Centers. Internal marketing was associated with organizational commitment and customer orientation. Customer orientation was associated with organizational commitment and partially mediated the relation between internal marketing and organizational commitment. Furthermore, work status significantly moderated the relationships between internal marketing and customer orientation but not between internal marketing and organizational commitment. Implications and directions for future research were discussed.

The purpose of this paper is to develop a causal model that explains the antecedents and mediating factors predicting the organizational commitment of healthcare employees in different work roles. This study tests an integrative causal model that consists of a number of direct and indirect relationships for antecedents of organizational commitment. It is proposed that the relationship between job satisfaction and organizational commitment is best understood by focusing on the three interrelated facets of job satisfaction, i.e. satisfaction with career advancement, satisfaction with supervisor, and satisfaction with co-workers. However, the model also advances that these job satisfaction facets have different mediating effects for other antecedents of organizational commitment. The Structural Equation Modeling (SEM) path analysis showed that the job satisfaction facets of career advancement and satisfaction with supervisor had a direct impact on organizational commitment. Employee empowerment, job-motivating potential, effective leadership, acceptance by co-workers, role ambiguity and role conflict were also important determinants of organizational commitment. Interestingly, post hoc analyses showed that satisfaction with co-workers only had an indirect impact on organizational commitment. While there has been extensive research on organizational commitment and its antecedents in healthcare organizations, most previous studies have been limited either to a single employee group or to a single time frame. This study proposes a practical causal model of antecedents of organizational commitment that tests relationships across time and across different healthcare employee groups.

Health professions depend on their faculties to prepare new practitioners, conduct research and provide essential services. Organizational commitment is an important aspect of faculty effectiveness and job performance, and may impact on turnover, absenteeism and interpersonal trust. A survey of organizational commitment, including faculty demographics and workplace variables, was conducted. Respondents were full- and part-time chiropractic faculty working in the United States and Canada. More than 54% of the study population (n = 609) completed and returned the instrument. A large majority of the respondents were male (68.4%) and employed full-time (81.6%). Almost half (47.5%) of the respondents were assigned to the area of patient care at their institutions. This study provides an initial assessment of organizational commitment among chiropractic faculty. Tenure in higher education, gender and age were found to be the most important predictors of organizational commitment.

An individual's loyalty or bond to his or her employing organization, referred to as organizational commitment, influences various organizational outcomes such as employee motivation, job satisfaction, performance, accomplishment of organizational goals, employee turnover, and absenteeism. Therefore, as in other sectors, employee commitment is crucial also in the healthcare market. This study investigates the effects of organizational factors and personal characteristics on organizational commitment of military physicians using structural equation modeling (SEM) on a self-report, cross-sectional survey that consisted of 635 physicians working in the 2 biggest military hospitals in Turkey. The results of this study indicate that professional commitment and organizational incentives contribute positively to organizational commitment, whereas conflict with organizational goals makes a significantly negative contribution to it. These results might help develop strategies to increase employee commitment, especially in healthcare organizations, because job-related factors have been found to possess greater impact on organizational commitment than personal characteristics.

The effect of occupational meaningfulness on occupational commitment

2014-11-01

Full Text Available Existing research lacks a scholarly consensus on how to define and validly measure ‘meaningful work’ (e.g., Rosso, Dekas & Wrzesniewski, 2010. The following correlational study highlights the value of investigating meaningfulness in the context of occupational commitment. The study hypothesizes that occupational commitment is positively correlated with occupational meaningfulness, where meaningfulness is defined as the extent to which people’s occupations contribute to personal meaning in life. One-hundred and fifty-six full-time office based UK workers completed an online questionnaire including 18 questions measuring levels of occupational commitment (Meyer, Allen & Smith, 1993, in addition to six novel items measuring occupational meaningfulness. The results supported the hypothesis and also showed that the affective sub-type of occupational commitment had the highest correlation with occupational meaningfulness. Such results exhibit the importance of finding meaning at work, as well as the relevance of this to one’s level of commitment to his or her job. This paper argues that individuals should consider OM before choosing to take a specific role, whereas organizations ought to consider the OM of their potential candidates before recruiting them into a role. Possible directions for future research directions are also discussed.

Full Text Available The objective of this paper is to investigate the effect of the ethical climate on the organizational commitment, professional commitment and job satisfaction of Malaysian auditors. Using a survey questionnaire comprising instruments about the ethical climate, organizational commitment, professional commitment and job satisfaction, 263 usable responses were received. To achieve the objectives, mean scores, standard deviations, correlations and multiple regressions were performed. The study revealed that a significant positive influence of a caring ethical climate on professional and organizational commitment as well as job satisfaction existed. There was also a positive significant association between the law and code ethical climate and professional commitment. On the other hand, the study discovered that the instrumental ethical climate type had a significant negative relationship with organizational commitment and job satisfaction. A significant negative relationship was also revealed between the independent ethical climate type and organizational and professional commitment. A significant negative relationship between the rules ethical climate and job satisfaction was also discovered.

Antecedents of Corporate Environmental Commitments: The Role of Customers.

The management of natural environments has become a fundamental issue for companies in recent years. A firm’s environmental commitment affects all levels of its operation. In this study, we investigated whether having an effective and constant relationship with customers over time (customer capital) makes a difference to firms with a high environmental commitment compared with less environmentally committed firms. We found support for our idea by using original survey data from 149 small and medium-sized enterprises (SMEs) in Iran (2016⁻2017). Furthermore, we found that customer capital enhances environmental collaboration with customers which, in turn, has a positive impact on the firm’s environmental commitments. These findings provide empirical evidence for the important role of “getting closer to customers” as a way of enhancing corporate environmental responsibility in developing countries with weak institutional environments.

Petitioning for Involuntary Commitment for Chemical Dependency by Medical Services.

Science.gov (United States)

Lamoureux, Ian C; Schutt, Paul E; Rasmussen, Keith G

2017-09-01

Patients who have chemical dependency (CD) are commonly encountered on medical and surgical wards, often for illnesses and injuries sustained as a direct result of their substance abuse. When these patients are repeatedly admitted to the hospital in certain states that provide a legal framework to commit chemically dependent persons to a treatment facility, clinicians often wonder whether they should initiate that process. Should consulting psychiatrists choose to initiate the commitment process, they put into motion a resource-intensive, time-consuming mechanism, with uncertain outcomes, both in the courtroom and at the bedside. Petitioning for involuntary commitment to chemical dependency treatment of a patient from medical and surgical services is poorly understood. In this study, we examined a series of patients for whom petitions for judicial commitment in the state of Minnesota were entered over a 12-month period, and evaluated the likelihood of commitment to treatment, the demographics of patients involved, and the outcomes for this series of patients. Three vignettes are presented to illustrate the severity of these patients' illnesses and potential outcomes of the process. We further describe potential limitations of the commitment system and alternatives to CD commitment that could be explored further. © 2017 American Academy of Psychiatry and the Law.

Shared use agreements and leisure time physical activity in North Carolina public schools.

2017-02-01

Although increasing community access to public schools through shared use agreements (SUAs) has been a recommended strategy for promoting physical activity (PA) among national, state and local organizations, empirical evidence examining the efficacy of SUAs is limited. This study examined the degree of usage and production of PA among schools with shared use, and how variation in PA output is related to characteristics of the school, type of activity, facility type, and when activity occurs. Data were collected in 20 schools across North Carolina using System for Observing Play and Recreation in Communities (SOPARC) and Structured Physical Activity Surveys (SPAS) to assess PA in school athletic facilities during out of school time. Findings indicated that although schools had a policy of shared or open use, most facilities were empty during non-school hours. Hierarchal linear regression models also showed that formal programming was positively associated with both use and PA levels. Given the abundance of empty facilities, community groups in need of space to facilitate structured PA programs should pursue avenues of sharing facilities with public schools. Furthermore, to increase the efficacy of shared use, structured physical activity programs may be needed. Future studies are encouraged to further explore the effects of the specific types of shared use programs on PA production as well other aspects of the built environment surrounding schools.

Positive Feedback of NDT80 Expression Ensures Irreversible Meiotic Commitment in Budding Yeast

Science.gov (United States)

Tsuchiya, Dai; Yang, Yang; Lacefield, Soni

2014-01-01

In budding yeast, meiotic commitment is the irreversible continuation of the developmental path of meiosis. After reaching meiotic commitment, cells finish meiosis and gametogenesis, even in the absence of the meiosis-inducing signal. In contrast, if the meiosis-inducing signal is removed and the mitosis-inducing signal is provided prior to reaching meiotic commitment, cells exit meiosis and return to mitosis. Previous work has shown that cells commit to meiosis after prophase I but before entering the meiotic divisions. Since the Ndt80 transcription factor induces expression of middle meiosis genes necessary for the meiotic divisions, we examined the role of the NDT80 transcriptional network in meiotic commitment. Using a microfluidic approach to analyze single cells, we found that cells commit to meiosis in prometaphase I, after the induction of the Ndt80-dependent genes. Our results showed that high-level expression of NDT80 is important for the timing and irreversibility of meiotic commitment. A modest reduction in NDT80 levels delayed meiotic commitment based on meiotic stages, although the timing of each meiotic stage was similar to that of wildtype cells. A further reduction of NDT80 resulted in the surprising finding of inappropriately uncommitted cells: withdrawal of the meiosis-inducing signal and addition of the mitosis-inducing signal to cells at stages beyond metaphase I caused return to mitosis, leading to multi-nucleate cells. Since Ndt80 enhances its own transcription through positive feedback, we tested whether positive feedback ensured the irreversibility of meiotic commitment. Ablating positive feedback in NDT80 expression resulted in a complete loss of meiotic commitment. These findings suggest that irreversibility of meiotic commitment is a consequence of the NDT80 transcriptional positive feedback loop, which provides the high-level of Ndt80 required for the developmental switch of meiotic commitment. These results also illustrate the

2008-04-01

Few studies focused on nurses' career commitment and nurses' job performance. This research aimed at studying variables of nurses' career commitment and job performance, and assessing the relationship between the two concepts as well as their predictors. A survey was used to collect data from a convenient sample of 640 Registered Nurses employed in 24 hospitals. Nurses 'agreed' to be committed to their careers and they were performing their jobs 'well'. As a part of career commitment, nurses were willing to be involved, in their own time, in projects that would benefit patient care. The highest and lowest means of nurses' job performance were reported for the following aspects: leadership, critical care, teaching/collaboration, planning/evaluation, interpersonal relations/communications and professional development. Correlating of total scores of nurses' career commitment and job performance revealed the presence of a significant and positive relationship between the two concepts. Stepwise regression models revealed that the explained variance in nurses' career commitment was 23.9% and that in nurses' job performance was 29.9%. Nurse managers should promote nursing as a career and they should develop and implement various strategies to increase nurses' career commitment and nurses' job performance. These strategies should focus on nurse retention, staff development and quality of care. Nurses' career commitment and job performance are inter-related complex concepts that require further studies to understand, promote and maintain these positive factors in work environments.

Full Text Available The hospitality industry is facing major challenges, among them the new competition from novel forms of supply in the sharing economy. Airbnb, Homeaway, and Niumba, among other websites offering accommodations, are having an important impact in the sector, changing existing conditions and the market for the traditional hospitality industry. In this context, a strategy based in differentiation can help to prevent drops in revenues and profitability. The main objective of this paper is analyse if commitment towards sustainability has a positive impact on financial performance and can be considered a positive strategy in this new environment. The empirical data refer to a sample of hotels in Barcelona, one of the most important tourist cities in Europe. Our results suggest that there is no clear relationship between sustainability and better financial performance; however, sustainability commitment is associated with a minimum size, which can also have positive effects in terms of economies of scale and finally affect profitability. Hotels more committed to environmental issues are located in areas with a lower density of Airbnb apartments, and this geographical distribution can be more positive than a situation of massive tourist concentration in specific areas with negative externalities for neighbours.

2016-07-01

Nurse practitioners (NPs) deliver a wide array of healthcare services in a variety of settings. The purpose of this study was to examine the practice patterns and organizational commitment of inpatient NPs. A quantitative design was used with a convenience sample (n = 183) of NPs who attended the American Association of Nurse Practitioners (AANP) national conference. The NPs were asked to complete a demographic questionnaire, the Practice Patterns of Acute Nurse Practitioners tool and the Organizational Commitment Questionnaire. Over 85% of inpatient practice time consists of direct and indirect patient care activities. The remaining nonclinical activities of education, research, and administration were less evident in the NP's workweek. This indicates that the major role of inpatient NPs continues to be management of acutely ill patients. Moderate commitment was noted in the Organizational Commitment Questionnaire. Supportive hospital/nursing leadership should acknowledge the value of the clinical and nonclinical roles of inpatient NPs as they can contribute to the operational effectiveness of their organization. By fostering the organizational commitment behaviors of identification, loyalty, and involvement, management can reap the benefits of these professionally dedicated providers. ©2015 American Association of Nurse Practitioners.

Alcohol myopia and goal commitment

A. Timur Sevincer

2014-03-01

Full Text Available According to alcohol-myopia theory, acute alcohol consumption leads people to disproportionally focus on the salient rather than the peripheral aspects of a situation. We summarize various studies exploring how myopic processes resulting from acute alcohol intake affect goal commitment. After consuming alcohol student participants felt strongly committed to an important personal goal even though they had low expectations of successfully attaining the goal. However, once intoxicated participants were sober again (i.e., not myopic anymore they failed to act on their goal commitment. In line with alcohol-myopia theory, strong goal commitment as a result of alcohol intake was mediated by intoxicated (vs. sober participants disproportionally focusing on the desirability rather than the feasibility of their goal. Further supporting alcohol-myopia theory, when the low feasibility of attaining a particular goal was experimentally made salient (either explicitly or implicitly by subliminal priming, intoxicated participants felt less committed than those who consumed a placebo. We discuss these effects of acute alcohol intake in the context of research on the effects of chronic alcohol consumption on goal commitment.

Analysis on Time Window of Shared Parking in Hospitals Based on Parking Behaviors

Directory of Open Access Journals (Sweden)

Qin Chen

2017-01-01

Full Text Available Hospitals are essential components of a city; huge traffic demand is generated and attracted, causing contradiction between parking supply and demand. By sharing parking berths, limited space can serve more demand which is beneficial to alleviating parking problems. Aimed at improving the capacity of shared parking, the paper analyzes four parking groups in typical hospitals, which are medical staff, outpatients, emergency patients, and visiting groups. The parking demand of medical staff is rigid. For outpatients and visiting groups, longer walking distance is acceptable and more attention is paid to parking fee. By contrast, emergency patients can accept shorter walking distance and focus more on convenience due to urgency. Under this circumstance, parking behaviors selection models are established by means of Multinomial Logit Model. On this basis, time value is adopted to calculate the tolerance of alterative parking time. Moreover, this paper explores the variation of time window, under different parking impedance. A case study is conducted and suggests that start and end point of a certain time window can be influenced by external factors.

Cahoon, Peter; Forsey, David R.; Hutchison, Susan

1999-03-01

During the past five years a high speed ATM network has been developed at UBC that provides a campus testbed, a local testbed to the hospitals, and a National testbed between here and the BADLAB in Ottawa. This testbed has been developed to combine a commercial shared audio/video/whiteboard environment coupled with a shared interactive 3-dimensional solid model. This solid model ranges from a skull reconstructed from a CT scan with muscles and an overlying skin, to a model of the ventricle system of the human brain. Typical interactions among surgeon, radiologist and modeler consist of having image slices of the original scan shared by all and the ability to adjust the surface of the model to conform to each individuals perception of what the final object should look like. The purpose of this interaction can range from forensic reconstruction from partial remains to pre-maxillofacial surgery. A joint project with the forensic unit of the R.C.M.P. in Ottawa using the BADLAB is now in the stages of testing this methodology on a real case beginning with a CT scan of partial remains. A second study underway with the department of Maxiofacial reconstruction at Dalhousie University in Halifax Nova Scotia and concerns a subject who is about to undergo orthognathic surgery, in particular a mandibular advancement. This subject has been MRI scanned, a solid model constructed of the mandible and the virtual surgery constructed on the model. This model and the procedure have been discussed and modified by the modeler and the maxillofacial specialist using these shared workspaces. The procedure will be repeated after the actual surgery to verify the modeled procedure. The advantage of this technique is that none of the specialists need be in the same room, or city. Given the scarcity of time and specialists this methodology shows great promise. In November of this last year a shared live demonstration of this facial modeler was done between Vancouver and Dalhousie University in

Decision of special monitoring time to minimize the difference of the committed effective dose evaluated from the different AMAD

International Nuclear Information System (INIS)

Lee, J. I.; Lee, T. Y.; Jang, S. Y.; Lee, J. K.

2003-01-01

The Committed Effective Doses (CEDs) per measured unit of activity in the bioassay compartments at any time (t) after an acute intake by the inhalation of a radionuclide with a different particle size (AMAD) were calculated and compared. As a result, the relative difference between the CEDs evaluated from the different AMAD is affected by the radionuclide, bioassay compartment, and the time (t) after intake. Therefore a special monitoring time to exclude or reduce the effect of AMAD was decided and presented in the evaluation for the CEDs following an acute intake by the inhalation of a radionuclide. If special monitoring is performed during this presented special time after intake, the relative difference of the evaluated CEDs resulted from AMAD can be excluded or reduced

Pledges of Commitment and Cooperation in Partnerships

Directory of Open Access Journals (Sweden)

Lachlan Deer

2016-01-01

Full Text Available We use experimental methods to investigate whether pledges of commitment can improve cooperation in endogenously-formed partnerships facing a social dilemma. Treatments vary in terms of the individual’s: (1 opportunity to commit to their partner; (2 the cost of dissolving committed partnerships; and (3 the distribution of these dissolution costs between partners. Our findings show that pledges of commitment alone can increase cooperation and welfare in committed partnerships. The introduction of relatively large and equally split costs yields similar gains. In contrast, when costs to dissolve committed partnerships fall solely on the individual choosing to break up, pledges of commitment fail to improve cooperation and welfare.

INPO and the industry: a commitment to excellence

International Nuclear Information System (INIS)

Colvin, J.F.

1985-01-01

Utilities in the United States have undergone major changes in their attitudes and methods of operating nuclear stations in the 6 yr since the accident at Three Mile Island. These changes reflect a strong commitment by the US utility industry to excellence in nuclear plant operations. Fundamental in this commitment was the formation of the Institute of Nuclear Power Operations (INPO), an organization created by the industry in the United States to serve as a focus and catalyst for these changes. With membership in INPO, nuclear utilities make a commitment to strive for excellence in the construction and operation of their nuclear plants. INPO has programs to help utilities in their efforts to achieve excellence. The most visible are the INPO evaluation programs. By the end of 1985, INPO will have evaluated most operating plants at least four times. Construction project evaluations are also being conducted. Twenty-one construction evaluations will have been conducted by the end of the year. Through each of its programs, INPO seeks to promote excellence and to help those operating and building nuclear plants in their commitment to excellence

Perceptions of internal marketing and organizational commitment by nurses.

Chang, Ching Sheng; Chang, Hae Ching

2009-01-01

This paper is a report of a study to determine whether a favourable perception of internal marketing is associated with increased organizational commitment. The role of nurses in healthcare treatment is expanding, and becoming more important as time progresses. Therefore, the primary concern of business of health care is to use internal marketing strategies effectively to enhance and develop nurses' organizational commitment and reduce turnover to promote competitive advantages for the organization. A cross-sectional design was used. Questionnaires were distributed in 2006 to a convenience sample of 450 Registered Nurses in two teaching hospitals in Taiwan, and 318 questionnaires were returned. Eighteen were excluded because of incomplete answers, which left 300 usable questionnaires (response rate 66.7%). Validity and reliability testing of the questionnaire proved satisfactory and Structural Equation Modeling was used to analyse the data. A favourable perception of internal marketing was associated with increased organizational commitment. Communication management had the greatest influence on organizational commitment and external activity had the smallest impact. Hospital managers need to recognize the importance of internal marketing for staff retention and the survival of their organizations as competitive pressure increases. As a great deal of time and costs are involved in educating nurses, the best way to retain outstanding nurses and reduce turnover costs and personnel problems is for employers to understand the needs and expectations of their nursing staff.

Global mean sea level has been steadily rising over the last century, is projected to increase by the end of this century, and will continue to rise beyond the year 2100 unless the current global mean temperature trend is reversed. Inertia in the climate and global carbon system, however, causes the global mean temperature to decline slowly even after greenhouse gas emissions have ceased, raising the question of how much sea-level commitment is expected for different levels of global mean temperature increase above preindustrial levels. Although sea-level rise over the last century has been dominated by ocean warming and loss of glaciers, the sensitivity suggested from records of past sea levels indicates important contributions should also be expected from the Greenland and Antarctic Ice Sheets. Uncertainties in the paleo-reconstructions, however, necessitate additional strategies to better constrain the sea-level commitment. Here we combine paleo-evidence with simulations from physical models to estimate the future sea-level commitment on a multimillennial time scale and compute associated regional sea-level patterns. Oceanic thermal expansion and the Antarctic Ice Sheet contribute quasi-linearly, with 0.4 m °C(-1) and 1.2 m °C(-1) of warming, respectively. The saturation of the contribution from glaciers is overcompensated by the nonlinear response of the Greenland Ice Sheet. As a consequence we are committed to a sea-level rise of approximately 2.3 m °C(-1) within the next 2,000 y. Considering the lifetime of anthropogenic greenhouse gases, this imposes the need for fundamental adaptation strategies on multicentennial time scales.

CERN Confirms commitment to Open Access

CERN Multimedia

2005-01-01

The CERN Library Information desk.At a meeting on the Wednesday before Easter, the Executive Committee endorsed a policy of open access to all the laboratory's results, as expressed in the document ‘Continuing CERN action on Open Access' (http://cds.cern.ch/record/828991/files/open-2005-006.pdf), released by its Scientific Information Policy Board (SIPB) earlier in the month. "This underlines CERN's commitment to sharing the excitement of fundamental research with as wide an audience as possible", said Guido Altarelli, current SIPB chairman. Open Access to scientific knowledge is today the goal of an increasing component of the worldwide scientific community. It is a concept, made possible by new electronic tools, which would bring enormous benefits to all readers by giving them free access to research results. CERN has implicitly supported such moves from its very beginning. Its Convention (http://cds.cern.ch/record/330625/files/cm-p00046871.pdf), adopted in 1953, requires openness, stipulating that "......

Absolute symbolic addressing, a structure making time-sharing easier

International Nuclear Information System (INIS)

Debraine, P.

1968-08-01

Time-sharing of computers asks for a certain number of conditions, particularly, an efficient dynamic loading of programs and data. This paper indicates a paging method making linkages with a minimum of table-looking operations. The principle is to use associative memory registers for calling blocks of physical memory, the block address being given by the concatenation of a file number (located in a base register) and a page number (located in the instruction proper). The position within the block is given by a displacement located in the instruction. A second associated base register contains the local part (page number + displacement) of the base address. This extended base register system allows executing programs in a very large programming complex without loss of time. The addresses are fixed at assembly time and the blocks can be loaded anywhere without modification for execution. The various problems associated with the execution of complex programs are presented in this context and shown to be easily solved by the proposed system, the realization of which would be very easy starting from the computer structures existing now.

Commitment devices may be better characterised as a signal of some innate motivation at the time of take up, rather than a substantive instrument for behaviour change, on average. However, heterogeneity of treatment effects may play an important part in explaining how and when commitment devices are most effective. If commitment devices can work well for identifiable sub-groups, there may yet be a targeted role for them in the public policy toolkit.

Bamberg, Richard; Akroyd, Duane; Moore, Ti'eshia M

2008-01-01

To assess the predictive ability of various aspects of the work environment for organizational commitment. A questionnaire measuring three dimensions of organizational commitment along with five aspects of work environment and 10 demographic and work setting characteristics was sent to a national, convenience sample of clinical laboratory professionals. All persons obtaining the CLS certification by NCA from January 1, 1997 to December 31, 2006. Only respondents who worked full-time in a clinical laboratory setting were included in the database. Levels of affective, normative, and continuance organizational commitment, organizational support, role clarity, role conflict, transformational leadership behavior of supervisor, and organizational type, total years work experience in clinical laboratories, and educational level of respondents. Questionnaire items used either a 7-point or 5-point Likert response scale. Based on multiple regression analysis for the 427 respondents, organizational support and transformational leadership behavior were found to be significant positive predictors of affective and normative organizational commitment. Work setting (non-hospital laboratory) and total years of work experience in clinical laboratories were found to be significant positive predictors of continuance organizational commitment. Overall the organizational commitment levels for all three dimensions were at the neutral rating or below in the slightly disagree range. The results indicate a less than optimal level of organizational commitment to employers, which were predominantly hospitals, by CLS practitioners. This may result in continuing retention problems for hospital laboratories. The results offer strategies for improving organizational commitment via the significant predictors.

Claude-Hélène Mayer

2015-08-01

Full Text Available Objective: This study focuses on an assessment of managerial job satisfaction and commitment in the context of a vibrant and rapidly changing public utility from a positive organisational behaviour (POB perspective. It aims at contributing towards an in-depth understanding of positive micro-organisational behaviour. Problem investigated: The aim of this study was to gain deeper insights into the relationship between job satisfaction (JS and organisational commitment (OC in terms of the ‘how and why’ at a selected public utility in the Eastern Cape Province. Design: This single case study uses a mixed-method approach within the pragmatism research paradigm. Findings: Findings show that managers across cultures share a positive organisational psychology approach on JS and OC. The JS of managers is mainly influenced by their satisfaction with working with colleagues and supervisors, and with strategies of motivation, as well as their dissatisfaction with the use of power, pay and promotion. OC was mainly influenced by positive collegial relationships, the organisation’s positive influence on the environment and on others, the enabling work environment and the location of the organisation. Originality/value: The article introduces new ideas in positive organisational behaviour research and reconstructs the image of South African organisational behaviour based on qualitative and quantitative data. Conclusion: This article shows that post-modern African organisations are opening new frontiers to building positive-oriented organisational cultures whilst creating constructive and future-orientated mindsets, which may spill over into society.

Radiographers' commitment to continuing professional development: A single-centre evaluation

International Nuclear Information System (INIS)

Stevens, Barry J.

2016-01-01

Purpose: This study aimed to examine radiographers' commitment to continuing professional development (CPD), and to ascertain what types of activities are preferred so a model for provision of departmental activities could be developed. Methods: An online survey was used to obtain information from all departmental radiographers regarding their commitment to CPD. Statistical analysis, using Spearman's Rho and Chi-Square test, was utilised to investigate any associations. Results: All radiographers (n = 57) were invited via email. A response rate of 67% (n = 38) prevailed. Radiographers feel CPD is important and a positive correlation existed with feelings regarding compulsory CPD (r value = .718, P value = .001). Thirty-four percent had logged the SOR-recommended twelve or more pieces of CPD in the last 2 years. One to three hours a month is the preferred amount of own time radiographers are willing to dedicate. Negative correlations exist between the amount of own time radiographers are willing to commit to CPD activities and their feelings regarding compulsory CPD (r value = −.419, P value = .009), and HCPC audit (r value = −.509, P value .001). Conclusion: Although radiographers recognise the importance of CPD many spend less than four hours of their own time a month on CPD. Departmental activities should be free, short lasting, lunchtime presentations with theory presentation that encourage interaction and discussion with inclusion of practical elements. Further research investigating the barriers that prevent radiographers from partaking in CPD and the causes for insufficient CPD records is recommended. - Highlights: • The large majority of radiographers feel CPD is important or very important to them. • The majority had positive opinions regarding compulsory CPD and HCPC audit. • 50% of radiographers commit less than 4 h of their own time to CPD. • As radiographers get older they log less CPD and commit less time to CPD. �

Organizational Commitment, Psychological Contract Fulfillment and Job Performance: A Longitudinal Quanti-qualitative Study

Directory of Open Access Journals (Sweden)

Leticia Gomes Maia

2015-07-01

Full Text Available The goals of this study are to contribute to the understanding of the development of organizational commitment and to explore the relations among psychological contract fulfillment, organizational commitment, and job performance. This paper reports the findings of a longitudinal quanti-qualitative study conducted with newcomers over three years. We identified four trajectories of commitment development: Learning to Love, High Match, Honeymoon Hangover and Learning to Hate. The last one is originally proposed in this study, and it is represented by individuals who began work highly committed to the organization, but then their commitment levels decreased dramatically over time. We discuss some characteristics associated with these trajectories. Our results corroborate the assumption that psychological contract fulfillment is positively related to commitment. Nevertheless, our findings about the relationship between commitment and job performance were different according to the trajectories. The trajectories Learning to Love and Learning to Hate support the assumption that higher commitment levels would lead to better performance, and vice versa; however, the trajectories High Match and Honeymoon Hangover contradict it. We offer and discuss some possible explanations for these findings.

Committed dose equivalent in the practice of radiological protection

International Nuclear Information System (INIS)

Nenot, J.C.; Piechowski, J.

1985-01-01

In the case of internal exposure, the dose is not received at the moment of exposure, as happens with external exposure, since the incorporated radionuclide irradiates the various organs and tissues during the time it is present in the body. By definition, the committed dose equivalent corresponds to the received dose integrated over 50 years from the date of intake. In order to calculate it, one has to know the intake activity and the value of the committed dose equivalent per unit of intake activity. The uncertainties of the first parameter are such that the committed dose equivalent can only be regarded as an order of magnitude and not as a very accurate quantity. The use of it is justified, however, for, like the dose equivalent for external exposure, it expresses the risk of stochastic effects for the individual concerned since these effects, should they appear, would do so only after a latent period which is generally longer than the dose integration time. Moreover, the use of the committed dose equivalent offers certain advantages for dosimetric management, especially when it is simplified. A practical problem which may arise is that the annual dose limit is apparently exceeded by virtue of the fact that one is taking account, in the first year, of doses which will actually be received only in the following years. These problems are rare enough in practice to be dealt with individually in each case. (author)

This report discusses three main issues pertaining to burden sharing in the context of climate change policies: (1) The handling of a mix of climate gases and the influence on the cost-effective choice of policy measures, (2) The concept of measurement of emission reduction costs and compares these costs across countries, and (3) The climate protocol negotiations, including ethical principles. The final chapter compares national circumstances in different countries and identifies groups of countries having similar interests in the negotiations. It is found that: (1) The Global Warming Potential method is the only realistic tool for comparison of different greenhouse gases, (2) The available methodologies for comparing the effects of greenhouse gases restrict the gases to be included in negotiations, (3) A moderate climate policy is beneficial, (4) In terms of cost-effectiveness and fairness, an agreement which emphasises measures like removal of subsidies on fossil fuels or minimum fossil fuel taxes, might have advantages over agreements which rely mainly on quantified national reduction commitments, (5) The burden sharing rules that could be defined based on available data may have quite different burden sharing and welfare implications for different OECD countries, (6) The achievable outcome of the negotiations in terms of a common OECD target is likely to be determined by countries with relatively low concern for climate change and either low or high abatement costs, (7) The achievable common target for OECD depends on the incorporation into the agreements of elements that reduce the cost share of high abatement cost countries, thus moving from `emission reduction sharing` to `cost sharing`. 95 refs., 52 figs., 22 tabs.

Virtual machine migration in an over-committed cloud

KAUST Repository

Zhang, Xiangliang

2012-04-01

While early emphasis of Infrastructure as a Service (IaaS) clouds was on providing resource elasticity to end users, providers are increasingly interested in over-committing their resources to maximize the utilization and returns of their capital investments. In principle, over-committing resources hedges that users - on average - only need a small portion of their leased resources. When such hedge fails (i.e., resource demand far exceeds available physical capacity), providers must mitigate this provider-induced overload, typically by migrating virtual machines (VMs) to underutilized physical machines. Recent works on VM placement and migration assume the availability of target physical machines [1], [2]. However, in an over-committed cloud data center, this is not the case. VM migration can even trigger cascading overloads if performed haphazardly. In this paper, we design a new VM migration algorithm (called Scattered) that minimizes VM migrations in over-committed data centers. Compared to a traditional implementation, our algorithm can balance host utilization across all time epochs. Using real-world data traces from an enterprise cloud, we show that our migration algorithm reduces the risk of overload, minimizes the number of needed migrations, and has minimal impact on communication cost between VMs. © 2012 IEEE.

Factors Affecting Organizational Commitment in Navy Corpsmen.

2017-07-01

Organizational commitment is a psychological state that has a strong impact on the likelihood that employees will remain with an organization. Among military personnel, organizational commitment is predictive of a number of important outcomes, including reenlistment intentions, job performance, morale, and perceived readiness. Because of the unique challenges and experiences associated with military service, it may be that organizational commitment is even more critical in the military than in civilian populations. Despite the essential role that they play in protecting the health of other service members, little is known about the factors that influence Navy Corpsmen's organizational commitment. This study investigated demographic and psychosocial factors that may be associated with organizational commitment among Corpsmen. Surveys of organizational commitment and possible demographic and psychosocial correlates of organizational commitment were completed by 1,597 male, active duty Navy Corpsmen attending Field Medical Training Battalion-West, Camp Pendleton, California. Bivariate correlations and hierarchical multiple regression analyses were used to determine significant predictors of organizational commitment. Of the 12 demographic and psychosocial factors examined, 6 factors emerged as significant predictors of organizational commitment in the final model: preservice motivation to be a Corpsman, positive perceptions of Corpsman training, confidence regarding promotions, occupational self-efficacy, social support for a Corpsman career, and lower depression. Importantly, a number of the factors that emerged as significant correlates of organizational commitment in this study are potentially modifiable. These factors include confidence regarding promotions, positive perceptions of Corpsman training, and occupational self-efficacy. It is recommended that military leaders and policy-makers take concrete steps to address these factors, thereby strengthening

2015-12-17

Factors associated with family commitment among pharmacists in the south central U.S. are explored. In 2010, a cross-sectional mailed self-administered 70 item survey of 363 active licensed pharmacists was conducted. This analysis includes only 269 (74%) participants who reported being married. Outcome measures were family commitment (need for family commitment, spouse's family commitment), work-related characteristics (work challenge, stress, workload, flexibility of work schedule), and job and career satisfaction. Married participants' mean age was 48 (SD = 18) years; the male to female ratio was 1:1; 73% worked in retail settings and 199 (74%) completed the family commitment questions. Females reported a higher need for family commitment than males ( p = 0.02) but there was no significant difference in satisfaction with the commitment. Work challenge and work load were significantly associated with higher need for family commitment ( p work status, and practice setting. Higher work challenge was associated with higher career satisfaction. Higher job related stress was associated with lower job satisfaction. High work challenge and work load may negatively impact family function since married pharmacists would need higher family commitment from their counterparts. The impact of work-family interactions on pharmacy career satisfaction should be further investigated.

Functional Flexibility in Women's Commitment-Skepticism Bias

Directory of Open Access Journals (Sweden)

Christina M. Brown

2015-04-01

Full Text Available If a woman overestimates her romantic partner's commitment, the cost to her fitness—reproduction without an investing partner—can be considerable. Error Management Theory predicts that women have an evolved bias to be skeptical of men's commitment in a relationship, which reduces the likelihood of making a costly false positive error. However, because error probabilities are inversely related, this commitment-skepticism bias simultaneously increases the likelihood of missed opportunities, or false negatives. False positives when gauging a partner's commitment are the more costly error for women, but missing an opportunity to secure a genuinely high-quality mate can also be quite costly. We predicted and found that women's mating cognitions are functionally flexible, such that women do not exhibit the commitment-skepticism bias when faced with behavioral evidence that a male partner is willing to commit (Study 1. This suggests that relationship-enhancing behaviors are one contextual cue that may lessen the bias. However, not all relationship-enhancing behaviors are equally diagnostic of a person's true commitment intent. When comparing men and women's commitment thresholds, we found that women require more behavioral evidence than men do to feel certain of their partner's commitment to them (Study 2.

Work challenge and work load were significantly associated with higher need for family commitment (p < 0.01, when controlled for age, gender, number of dependents, work status, and practice setting. Higher work challenge was associated with higher career satisfaction. Higher job related stress was associated with lower job satisfaction. High work challenge and work load may negatively impact family function since married pharmacists would need higher family commitment from their counterparts. The impact of work-family interactions on pharmacy career satisfaction should be further investigated.

The Effects of Abandonment Options on Investment Timing and Profit Sharing of FDI

Full Text Available The paper incorporates cooperative game theory into a real option method in a foreign direct investment setting and examines the operational decisions of a multinational corporation in a cooperative framework, where the corporation is endowed with an abandonment option and shares its profit with the host country. In particular, we investigate how the abandonment options affect the optimal investment timing and the optimal profit share of a foreign direct investment using a real option game method. We show that the flexibility of the abandonment option induces the corporation to investment earlier, which indicates the negative effects on investment trigger. The result is consistent with intuition since the abandonment option provides insurance and thus reduces the overall risk of the project. We also find that the introduction of the abandonment option reduces the optimal profit share in a cooperative framework and in turn the lower profit share increases the investment trigger, thereby having a positive effect on the investment threshold to hinder the investment. By numerical analysis, we find that the overall effect of the abandonment options is inversely related to the investment trigger. These findings provide quantitative analysis about the decisions regarding cooperation in international investment extraction projects.

Full Text Available Organizational commitment is an important issue and organization attitude has become an area of study among many researchers in the fields of organizational behavior. In fact, there are many studies on human resource management where the effects of organizational commitment on other issues have been investigated and the purpose of this research is to find critical factors influencing on organizational commitment. Based on an exploration of the literature review and interviews, the proposed study of this paper extracts 24 variables and using factor analysis, we select the most important factors, which are grouped in four categories. The implementation of our factor analysis has revealed Affective commitment, Continuous commitment, Moral commitment and Enduring commitment are the most important factors influencing organizational commitment.

Validating Teacher Commitment Scale Using a Malaysian Sample

Directory of Open Access Journals (Sweden)

Lei Mee Thien

2014-05-01

Full Text Available This study attempts to validate an integrative Teacher Commitment scale using rigorous scale validation procedures. An adapted questionnaire with 17 items was administered to 600 primary school teachers in Penang, Malaysia. Data were analyzed using exploratory factor analysis (EFA and confirmatory factor analysis (CFA with SPSS 19.0 and AMOS 19.0, respectively. The results support Teacher Commitment as a multidimensional construct with its four underlying dimensions: Commitment to Student, Commitment to Teaching, Commitment to School, and Commitment to Profession. A validated Teacher Commitment scale with 13 items measured can be proposed to be used as an evaluative tool to assess the level to which teachers are committed to their students’ learning, teaching, school, and profession. The Teacher Commitment scale would also facilitate the identifications of factors that influence teachers’ quality of work life and school effectiveness. The practical implications, school cultural influence, and methodological limitations are discussed.

The post-2012 climate policy framework needs a global commitment to deep greenhouse gas emission cuts. This paper analyzes reaching ambitious emission targets up to 2050, either -10% or -50% from 1990 levels, and how the economic burden from mitigation efforts could be equitably shared between countries. The scenarios indicate a large low-cost mitigation potential in electricity and industry, while reaching low emission levels in international transportation and agricultural emissions might prove difficult. The two effort sharing approaches, Triptych and Multistage, were compared in terms of equitability and coherence. Both approaches produced an equitable cost distribution between countries, with least developed countries having negative or low costs and more developed countries having higher costs. There is, however, no definitive solution on how the costs should be balanced equitably between countries. Triptych seems to be yet more coherent than other approaches, as it can better accommodate national circumstances. Last, challenges and possible hindrances to effective mitigation and equitable effort sharing are presented. The findings underline the significance of assumptions behind effort sharing on mitigation potentials and current emissions, the challenge of sharing the effort with uncertain future allowance prices and how inefficient markets might undermine the efficiency of a cap-and-trade system.

Sharing family and household:

DEFF Research Database (Denmark)

Winther, Ida Wentzel

Keynote: Family relationships are normatively assumed to be characterized by ‘sharing’, such as living together in the same home, occupying the same place, sharing stuff, blood and biology, spending special and ordinary time together, and consequently creating shared biographical experiences....... In that way, families are thrown into togetherness. At the same time, we see families in varying forms where 'sharing' is lived and contested differently. In Denmark, many children live in nuclear families, and many live in different variations of more than one household. For those who share household...... and family, 'sharing' will be a basic condition. No matter what, they should share life circumstances, more stories, more places and spaces, more households families with both kin and non-kin. This keynote addresses the particular of children’s experiences of living apart and/or living together in sharing...

Sharing as risk pooling in a social dilemma experiment

Directory of Open Access Journals (Sweden)

Todd L. Cherry

2015-03-01

Full Text Available In rural economies with missing or incomplete markets, idiosyncratic risk is frequently pooled through informal networks. Idiosyncratic shocks, however, are not limited to private goods but can also restrict an individual from partaking in or benefiting from a collective activity. In these situations, a group must decide whether to provide insurance to the affected member. We describe results of a laboratory experiment designed to test whether a simple sharing institution can sustain risk pooling in a social dilemma with idiosyncratic risk. We tested whether risk could be pooled without a commitment device and, separately, whether effective risk pooling induced greater cooperation in the social dilemma. We found that even in the absence of a commitment device or reputational considerations, subjects voluntarily pooled risk, thereby reducing variance in individual earnings. In spite of effective risk pooling, however, cooperation in the social dilemma was unaffected.

Effectiveness of shared leadership in Wikipedia.

Zhu, Haiyi; Kraut, Robert E; Kittur, Aniket

2013-12-01

The objective of the paper is to understand leadership in an online community, specifically, Wikipedia. Wikipedia successfully aggregates millions of volunteers' efforts to create the largest encyclopedia in human history. Without formal employment contracts and monetary incentives, one significant question for Wikipedia is how it organizes individual members with differing goals, experience, and commitment to achieve a collective outcome. Rather than focusing on the role of the small set of people occupying a core leadership position, we propose a shared leadership model to explain the leadership in Wikipedia. Members mutually influence one another by exercising leadership behaviors, including rewarding, regulating, directing, and socializing one another. We conducted a two-phase study to investigate how distinct types of leadership behaviors (transactional, aversive, directive, and person-focused), the legitimacy of the people who deliver the leadership, and the experience of the people who receive the leadership influence the effectiveness of shared leadership in Wikipedia. Our results highlight the importance of shared leadership in Wikipedia and identify trade-offs in the effectiveness of different types of leadership behaviors. Aversive and directive leadership increased contribution to the focal task, whereas transactional and person-focused leadership increased general motivation. We also found important differences in how newcomers and experienced members responded to leadership behaviors from peers. These findings extend shared leadership theories, contribute new insight into the important underlying mechanisms in Wikipedia, and have implications for practitioners who wish to design more effective and successful online communities.

Dependence on age at intake of committed dose equivalents from radionuclides

International Nuclear Information System (INIS)

Adams, N.

1981-01-01

The dependence of committed dose equivalents on age at intake is needed to assess the significance of exposures of young persons among the general public resulting from inhaled or ingested radionuclides. The committed dose equivalents, evaluated using ICRP principles, depend on the body dimensions of the young person at the time of intake of a radionuclide and on subsequent body growth. Representation of growth by a series of exponential segments facilitates the derivation of general expressions for the age dependence of committed dose equivalents if metabolic models do not change with age. The additional assumption that intakes of radionuclides in air or food are proportional to a person's energy expenditure (implying age-independent dietary composition) enables the demonstration that the age of the most highly exposed 'critical groups' of the general public from these radionuclides is either about 1 year or 17 years. With the above assumptions the exposure of the critical group is less than three times the exposure of adult members of the general public. Approximate values of committed dose equivalents which avoid both underestimation and excessive overestimation are shown to be obtainable by simplified procedures. Modified procedures are suggested for use if metabolic models change with age. (author)

The purpose of this study was to examine the main and interaction effects of perceived organisational support, span of control and leadership rank on novice nurse leaders' organisational commitment. As nurse leaders' organisational commitment is eroded at times of healthcare restructuring, it is important to study factors associated with organisational commitment. Cross-sectional data from 69 novice nurse leaders, collected via mailed surveys at two time points, were analysed using hierarchical regression. The findings supported our hypotheses about the positive effect of perceived organisational support, the positive effect of leadership rank and the negative effect of span of control on novice nurse leaders' organisational commitment. In addition, perceived organisational support was shown to moderate the negative effect of span of control on novice nurse leaders' organisational commitment at time 2. Organisational strategies aimed at supporting nurse leaders, and attention to span of control, are required to enhance the organisational commitment of novice nurse leaders. Nurse leaders with a wide span of control, in particular those with little leadership experience, need to adopt leadership strategies that maximise their effectiveness, such as organising smaller work groups or teams within their wide span of control. © 2013 John Wiley & Sons Ltd.

The influence of organizational commitment and health on sickness absenteeism: a longitudinal study.

Science.gov (United States)

Schalk, René

2011-07-01

The prevention of sickness absenteeism of nurses is an important issue for organizations in health care as well as for nurses. The role of work-related attitudes, such as organizational commitment, as a cause of absenteeism is still unclear. To examine the influence over time of organizational commitment, health complaints, and visits to a general practitioner on sickness absenteeism. This was a longitudinal, three-wave study in two nursing homes in the Netherlands among 224 nurses. Questionnaire data (self reports of organizational commitment, health complaints, visits to a general practitioner), as well as absenteeism data retrieved from personnel files was used. Health complaints and visits to a general practitioner were found to predict absenteeism behaviour. Commitment was related to health complaints at the same point in time, but did not predict future sickness absenteeism. With respect to managing sickness absenteeism of nurses it should be acknowledged by managers that nurses call in sick when they perceive that there is a real health problem, not because of negative work attitudes. It is important, however, for managers to signal signs of decreasing organizational commitment because this is associated with increases in health complaints. This can eventually result in increases in absenteeism. © 2011 The Author. Journal compilation © 2011 Blackwell Publishing Ltd.

  Professional commitment, or one's affinity and loyalty to a career, has become a topic of interest in athletic training. The expanding research on the topic, however, has omitted newly credentialed athletic trainers (ATs). For an impressionable group of practitioners, transitioning to clinical practice can be stressful.   To explore the professional commitment of newly credentialed ATs in the secondary school setting.   Secondary school.   Qualitative study.   A total of 31 newly credentialed ATs (6 men, 25 women; mean age = 24 ± 3 years) participated. Of these, 17 ATs (4 men, 13 women; mean age = 25 ± 4 years) were employed full time in the secondary school setting, and 14 ATs (2 men, 12 women; mean age = 23.0 ± 2.0 years) were graduate assistant students in the secondary school setting.   All participants completed semistructured interviews, which focused on their experiences in the secondary school setting and transitioning into the role and setting. Transcripts were analyzed using the phenomenologic approach. Creditability was established by peer review, member checks, and researcher triangulation.   Four main findings related to the professional commitment of newly credentialed ATs in the secondary school setting were identified. Work-life balance, professional relationships formed with the student-athletes, enjoyment gained from working in the secondary school setting, and professional responsibility emerged as factors facilitating commitment.   Affective commitment is a primary facilitator of professional commitment. Newly credentialed ATs who enjoy their jobs and have time to engage in nonwork roles are able to maintain a positive professional commitment. Our findings align with the previous literature and help strengthen our understanding that rejuvenation and passion are important to professional commitment.

Ng, Thomas W H; Feldman, Daniel C; Lam, Simon S K

2010-07-01

This study examined the relationships among psychological contract breaches, organizational commitment, and innovation-related behaviors (generating, spreading, implementing innovative ideas at work) over a 6-month period. Results indicate that the effects of psychological contract breaches on employees are not static. Specifically, perceptions of psychological contract breaches strengthened over time and were associated with decreased levels of affective commitment over time. Further, increased perceptions of psychological contract breaches were associated with decreases in innovation-related behaviors. We also found evidence that organizational commitment mediates the relationship between psychological contract breaches and innovation-related behaviors. These results highlight the importance of examining the nomological network of psychological contract breaches from a change perspective.

This paper presents a new approach to solve the short-term unit commitment problem using an evolutionary programming based simulated annealing method. The objective of this paper is to find the generation scheduling such that the total operating cost can be minimized, when subjected to a variety of constraints. This also means that it is desirable to find the optimal generating unit commitment in the power system for the next H hours. Evolutionary programming, which happens to be a global optimisation technique for solving unit commitment Problem, operates on a system, which is designed to encode each unit's operating schedule with regard to its minimum up/down time. In this, the unit commitment schedule is coded as a string of symbols. An initial population of parent solutions is generated at random. Here, each schedule is formed by committing all the units according to their initial status (''flat start''). Here the parents are obtained from a pre-defined set of solution's, i.e. each and every solution is adjusted to meet the requirements. Then, a random recommitment is carried out with respect to the unit's minimum down times. And SA improves the status. The best population is selected by evolutionary strategy. The Neyveli Thermal Power Station (NTPS) Unit-II in India demonstrates the effectiveness of the proposed approach; extensive studies have also been performed for different power systems consists of 10, 26, 34 generating units. Numerical results are shown comparing the cost solutions and computation time obtained by using the Evolutionary Programming method and other conventional methods like Dynamic Programming, Lagrangian Relaxation and Simulated Annealing and Tabu Search in reaching proper unit commitment.

China's renewable energy policy: Commitments and challenges

International Nuclear Information System (INIS)

Wang Feng; Yin Haitao; Li Shoude

2010-01-01

The passing of the Renewable Energy Law (REL) in 2005 demonstrated China's commitment to renewable energy development. In the 3 years after the REL, China's renewable electricity capacity grew rapidly. From 2006 to 2008, China's wind capacity installation more than doubled every year for 3 years in a row. However, three facts prevent us from being optimistic about China's renewable electricity future. First, considered as a share of total capacity, renewable electricity capacity is decreasing instead of increasing. This is due simply to the rapid growth of fossil fuel capacity. Second, a significant amount of renewable generation capacity is wasted because it is not connected to the electricity grid. Finally, renewable electricity plants are running at a low level of efficiency. Based on an in-depth analysis of China's existing renewable energy policy, we suggest that these challenges should be dealt with by introducing a market-based mandatory renewable portfolio requirement coupled with strong regulatory monitoring of grid enterprises.

Escalation of Commitment in the Surgical ICU.

Braxton, Carla C; Robinson, Celia N; Awad, Samir S

2017-04-01

Escalation of commitment is a business term that describes the continued investment of resources into a project even after there is objective evidence of the project's impending failure. Escalation of commitment may be a contributor to high healthcare costs associated with critically ill patients as it has been shown that, despite almost certain futility, most ICU costs are incurred in the last week of life. Our objective was to determine if escalation of commitment occurs in healthcare settings, specifically in the surgical ICU. We hypothesize that factors previously identified in business and organizational psychology literature including self-justification, accountability, sunk costs, and cognitive dissonance result in escalation of commitment behavior in the surgical ICU setting resulting in increased utilization of resources and cost. A descriptive case study that illustrates common ICU narratives in which escalation of commitment can occur. In addition, we describe factors that are thought to contribute to escalation of commitment behaviors. Escalation of commitment behavior was observed with self-justification, accountability, and cognitive dissonance accounting for the majority of the behavior. Unlike in business decisions, sunk costs was not as evident. In addition, modulating factors such as personality, individual experience, culture, and gender were identified as contributors to escalation of commitment. Escalation of commitment occurs in the surgical ICU, resulting in significant expenditure of resources despite a predicted and often known poor outcome. Recognition of this phenomenon may lead to actions aimed at more rational decision making and may contribute to lowering healthcare costs. Investigation of objective measures that can help aid decision making in the surgical ICU is warranted.

Physician as partner or salesman? Shared decision-making in real-time encounters.

Karnieli-Miller, Orit; Eisikovits, Zvi

2009-07-01

The results of recent research have led to the increased advocacy of shared decision-making regarding medical treatment. Nonetheless, only a limited number of studies have focused on the process of decision-making in real-time encounters. The present paper aims to document and analyze this process. Specifically, we assess whether these decisions are the result of partnership or of persuasive tactics based on power and hierarchical relationships. We will describe and analyze different strategies used by pediatric gastroenterologists in breaking bad news encounters, as well as their consequences. The analysis is based on a multi-method, multi-participant phenomenological study on breaking bad news to adolescents and their families regarding a chronic illness. It included 17 units of analysis (actual encounters and 52 interviews with physicians, parents and adolescents). Data were collected from three hospitals in Northern Israel using observations and audiotapes of diagnosis disclosure encounters and audio-taped interviews with all participants. The analysis identified eight different presentation tactics used in actual encounters during which physicians made various use of language, syntax and different sources of power to persuade patients to agree with their preferred treatment choice. The tactics included various ways of presenting the illness, treatment and side effects; providing examples from other success or failure stories; sharing the decision only concerning technicalities; and using plurals and authority. The findings suggest that shared decision-making may be advocated as a philosophical tenet or a value, but it is not necessarily implemented in actual communication with patients. Rather, treatment decisions tend to be unilaterally made, and a variety of persuasive approaches are used to ensure agreement with the physician's recommendation. The discussion is focused on the complexity of sharing a decision, especially in the initial bad news encounter

Commitment tracking in the licensing renewal process: A perspective

International Nuclear Information System (INIS)

Gurican, Gregory M.; Breslauer, Stephen K.

1991-01-01

The NRC's proposed 10 CFR 54 defines 'Current licensing basis' as inclusive of all licensee commitments. During the last five years, the regulatory commitment tracking group (RCTG) has been developing guidance for member utilities to track such commitments. The RCTG guidance for commitment tracking assists utilities in developing a system to store and maintain commitments related to the CLB. But a majority believe it unlikely that any one commitment tracking system will capture all commitments contained in the proposed definition of a 'Current Licencing Basis'. For future renewal applications the NRC proposes that utilities must identify and compile all licensing basis commitments. In addition, utilities 'shall maintain...(them) in an auditable and retrievable form'. Some utilities are already compiling and tracking licensing basis commitments; others are not. (author)

Commitment and Switching Intentions: Customers and Brands

Juliana Werneck Rodrigues

2012-12-01

Full Text Available This study aims to evaluate the relationship between a customer’s brand switching intentions and his commitment to a brand. Based on a literature review, constructs related to customer brand commitment were identified (affective and continuance commitment, trust, satisfaction, switching costs and alternative attractiveness and their roles in the formation of brand switching intentions hypothesized. Through a cross-sectional survey, a sample of 201 smartphone users was collected to test the proposed relationships. Data analysis was carried out via structural equations modeling, with direct effects of trust, satisfaction, switching costs and alternative attractiveness upon the different kinds of commitment being verified. Furthermore, both types of brand commitment (affective and continuance were found to negatively impact a customer’s intention to switch brands. Regarding enterprise customer strategies, the research findings suggest that, if firms are able to track customer brand commitment, they could use such knowledge to develop better relationship strategies, minimizing customer defection and further developing customer value to the company.

The purpose of this study was to examine the impact of selected organizational factors and the leadership behavior of supervisors on radiation therapists' commitment to their organizations. The population for this study consists of all full time clinical radiation therapists registered by the American Registry of Radiologic Technologists (ARRT) in the United States. A random sample of 800 radiation therapists was obtained from the ARRT for this study. Questionnaires were mailed to all participants and measured organizational variables; managerial leadership variable and three components of organizational commitment (affective, continuance and normative). It was determined that organizational support, and leadership behavior of supervisors each had a significant and positive affect on normative and affective commitment of radiation therapists and each of the models predicted over 40% of the variance in radiation therapists organizational commitment. This study examined radiation therapists' commitment to their organizations and found that affective (emotional attachment to the organization) and normative (feelings of obligation to the organization) commitments were more important than continuance commitment (awareness of the costs of leaving the organization). This study can help radiation oncology administrators and physicians to understand the values their radiation therapy employees hold that are predictive of their commitment to the organization. A crucial result of the study is the importance of the perceived support of the organization and the leadership skills of managers/supervisors on radiation therapists' commitment to the organization.

Mattingly, Brent A; Clark, Eddie M; Weidler, Daniel J; Bullock, Melinda; Hackathorn, Jana; Blankmeyer, Katheryn

2011-01-01

Individuals with an unrestricted sociosexual orientation (SO) are less committed to their romantic relationships and more likely to engage in infidelity. Furthermore, commitment is negatively associated with tendencies to cheat. However, no previous research has examined the possible mediating role of commitment in the relationship between SO and infidelity. The current study examined whether commitment mediated the relationship between SO and willingness to engage in three types of cheating behaviors (Ambiguous, Deceptive, and Explicit). Results suggested that commitment partially mediated the relationship between SO and infidelity, such that unrestricted individuals had lower commitment, which in turn led to a greater likelihood of cheating. Implications of this association and directions for future research are discussed.

Work-Family Conflict, Perceived Organizational Support and Professional Commitment: A Mediation Mechanism for Chinese Project Professionals.

Science.gov (United States)

Zheng, Junwei; Wu, Guangdong

2018-02-15

Projects are characterized by long working hours, complex tasks and being a kind of temporary organization. As such, work-family conflict is particularly prominent for project employees. This research examined whether and how work-family conflict affects professional commitment among Chinese project professionals. Research hypotheses were developed to explore the relationship between work-family conflict, professional commitment to the project and the mediating effects of perceived organizational support. Data were collected from 327 project managers or professionals working in construction enterprises in China; data were analyzed using structural equation modeling, applying the bootstrapping method. Results showed that there were three dimensions of work-family conflict: time-based conflict, strain-based conflict and behavior-based conflict. There were two dimensions of perceived organizational support: emotional support and instrumental support. The study also tested the negative effect of work-family conflict on professional commitment and the positive effect of perceived organizational support on professional commitment. Specifically, time-based conflict and emotional support had positive effects on professional commitment. Perceived organizational support had a total mediating effect between work-family conflict and professional commitment. The strain-based conflict dimension of work-family conflict had negative impacts on professional commitment through perceived emotional support and instrumental support. Overall, our findings extend a better understanding of work-family conflict and professional commitment in the project setting and verify the importance of social support in balancing work and family and improving employee mobility.

Projects are characterized by long working hours, complex tasks and being a kind of temporary organization. As such, work-family conflict is particularly prominent for project employees. This research examined whether and how work-family conflict affects professional commitment among Chinese project professionals. Research hypotheses were developed to explore the relationship between work-family conflict, professional commitment to the project and the mediating effects of perceived organizational support. Data were collected from 327 project managers or professionals working in construction enterprises in China; data were analyzed using structural equation modeling, applying the bootstrapping method. Results showed that there were three dimensions of work-family conflict: time-based conflict, strain-based conflict and behavior-based conflict. There were two dimensions of perceived organizational support: emotional support and instrumental support. The study also tested the negative effect of work-family conflict on professional commitment and the positive effect of perceived organizational support on professional commitment. Specifically, time-based conflict and emotional support had positive effects on professional commitment. Perceived organizational support had a total mediating effect between work-family conflict and professional commitment. The strain-based conflict dimension of work-family conflict had negative impacts on professional commitment through perceived emotional support and instrumental support.

2013-12-01

Full Text Available This paper presents an empirical investigation on the effects of job burnout and emotional intelligence on organizational commitment in an Iranian Carbon producer. There are 300 full time employees and the study chooses a sample of 169 people. The proposed study adopts three well-known questionnaires for measuring job burnout, emotional intelligence and organizational commitment and Cronbach alphas are 0.766, 0.877 and 0.802, respectively. The study chooses regression analysis and other statistical observation to examine different hypotheses and the results indicate that there were meaningful relationships among different components of the survey. In other words, when there was an increase on job burnout, we could expect less organizational commitment and while there was an increase on emotional intelligence, we may expect higher level of organizational commitment.

Full Text Available Signcryption is a cryptographic primitive which offers the functionality of both digital signature and encryption with lower combined computational cost. On the other hand, commitment scheme allows an entity to commit to a value, where the entity reveals the committed value later during a decommit phase. In this paper, we explore the connection between commitment schemes, public key encryption, digital signatures and signcryption. We establish formal relationship between commitment and the other primitives. Our main result is that we show signcryption can be used as a commitment scheme with appropriate security notions. We show that if the underlying signcryption scheme is IND-CCA2 secure, then the hiding property of the commitment scheme is satisfied. Similarly, we show that if the underlying signcryption scheme is unforgeable, then the relaxed biding property of the commitment scheme is satisfied. Moreover, we prove that if the underlying signcryption scheme is NM-CCA2, then the commitment scheme is non-malleable.

2017-01-01

Full Text Available Introduction. Nowadays, the problems of motivation of modern teachers and their valuable relation to the profession are actively being discussed in the scientific and pedagogical community. The changes in the relations between an employer and a teacher have been caused by the introduction of professional standards of the teacher and the extending practice of the conclusion of the socalled "effective contracts" between educational institutions and teachers. The aim of the present publication is to consider a phenomenon of professional commitment of teachers as a criterion of their psychological readiness for acceptance of new realities caused by the changed qualification competences having been imposed by the professional standard. Methodology and research methods. Comparative analysis and synthesis of the approaches to studying of a phenomenon of professional commitment existing in foreign psychology have been used. The empirical research of commitment of the Russian teachers to the profession was conducted on the basis of the authors’ method “The Questionnaire of Professional Commitment”. Statistical processing of the data obtained during the survey was carried out on the basis of the Statistica 7.0 program. The method of the factor analysis was applied. Results and scientific novelty. Yet, most studies in the field of the problematics of professional commitment have predominantly been carried out by foreign scholars. The attempt to describe the research experience on studying of professional commitment of the Russian teachers has been made for the first time ever. The proposed models of professional commitment are compared. It is proved that the structure of each model depends on professional and cultural diversity of a target group of a specific study. The specific features of psychological content of professional commitment of the Russian teachers are designated. Based on the systematized results of survey, the key structural

Research with substance-abusing samples suggests that eliciting commitment language during treatment may improve motivation to change, increase treatment engagement, and promote positive treatment outcomes. However, the relationship between in-session client language and treatment success is not well-understood for youth offender populations. This study evaluated the relationship between commitment language, treatment engagement (i.e., homework completion), and weekly employment outcomes for six gang-affiliated juvenile offenders participating in an employment counseling intervention. Weekly counseling sessions were audio-recorded, transcribed, and coded for commitment language strength. Multilevel models were fit to the data to examine the relationship between commitment language and counseling homework or employment outcomes within participants over time. Commitment language strength predicted subsequent homework completion but not weekly employment. These findings imply that gang-affiliated delinquent youth who express motivation to change during employment counseling will be more likely to comply with counselor-initiated homework. Further research on counselor techniques for promoting commitment language among juvenile gang offenders is needed. © The Author(s) 2013.

Understanding of the genetic regulation of puberty timing has come largely from studies of rare disorders and population-based studies in women. Here, we report the largest genomic analysis for puberty timing in 55,871 men, based on recalled age at voice breaking. Analysis across all genomic variants reveals strong genetic correlation (0.74, P=2.7 × 10(-70)) between male and female puberty timing. However, some loci show sex-divergent effects, including directionally opposite effects between sexes at the SIM1/MCHR2 locus (Pheterogeneity=1.6 × 10(-12)). We find five novel loci for puberty timing (Ppuberty, LEPR and KAL1. Finally, we identify genetic correlations that indicate shared aetiologies in both sexes between puberty timing and body mass index, fasting insulin levels, lipid levels, type 2 diabetes and cardiovascular disease.

2007-01-01

The study of the organizational commitment has risen interest within the organization's researchers, who have been trying to understand the intensity and stability of the individual's dedication to the organization. The interest that this construct has raised is based on the idea of the existence of an association of the organizational commitment with variables considered important to the increase of the organizational effectiveness and productivity. The aim of this article is to describe organizational commitment, in its affective, normative, and continuance dimensions, from nurse practitioners, and to analyze the differences of that commitment regarding gender. Data were collected by questionnaire. The sample is constituted by nurse practitioners who develop their professional activity in 6 Portuguese hospitals. Data were analyzed using means, standard deviation, and independent samples t test. The sample consists of 1201 nurses. The organizational commitment of the studied nurses is, on average, 2.87+/-0.69 (in 5-point scale). When we make an analysis regarding gender, we verify that the organizational commitment is higher in women, being the difference statistically significant (t = -2.07; P commitment in male and female nurses, and it is higher in all dimensions in female nurses; however, the difference is only significant to the organizational and continuance commitment.

Committed CO2 Emissions of China's Coal-fired Power Plants

Science.gov (United States)

Suqin, J.

2016-12-01

The extent of global warming is determined by the cumulative effects of CO2 in the atmosphere. Coal-fired power plants, the largest anthropogenic source of CO2 emissions, produce large amount of CO2 emissions during their lifetimes of operation (committed emissions), which thus influence the future carbon emission space under specific targets on mitigating climate change (e.g., the 2 degree warming limit relative to pre-industrial levels). Comprehensive understanding of committed CO2 emissions for coal-fired power generators is urgently needed in mitigating global climate change, especially in China, the largest global CO2emitter. We calculated China's committed CO2 emissions from coal-fired power generators installed during 1993-2013 and evaluated their impact on future emission spaces at the provincial level, by using local specific data on the newly installed capacities. The committed CO2 emissions are calculated as the product of the annual coal consumption from newly installed capacities, emission factors (CO2emissions per unit crude coal consumption) and expected lifetimes. The sensitivities about generators lifetimes and the drivers on provincial committed emissions are also analyzed. Our results show that these relatively recently installed coal-fired power generators will lead to 106 Gt of CO2 emissions over the course of their lifetimes, which is more than three times the global CO2 emissions from fossil fuels in 2010. More than 80% (85 Gt) of their total committed CO2 will be emitted after 2013, which are referred to as the remaining emissions. Due to the uncertainties of generators lifetime, these remaining emissions would increase by 45 Gt if the lifetimes of China's coal-fired power generators were prolonged by 15 years. Furthermore, the remaining emissions are very different among various provinces owing to local developments and policy disparities. Provinces with large amounts of secondary industry and abundant coal reserves have higher committed

The Developing Countries Vaccine Manufacturers' Network (DCVMN) held its fifteenth annual meeting from October 27-29, 2014, New Delhi, India. The DCVMN, together with the co-organizing institution Panacea Biotec, welcomed over 240 delegates representing high-profile governmental and nongovernmental global health organizations from 36 countries. Over the three-day meeting, attendees exchanged information about their efforts to achieve their shared goal of preventing death and disability from known and emerging infectious diseases. Special praise was extended to all stakeholders involved in the success of polio eradication in South East Asia and highlighted challenges in vaccine supply for measles-rubella immunization over the coming decades. Innovative vaccines and vaccine delivery technologies indicated creative solutions for achieving global immunization goals. Discussions were focused on three major themes including regulatory challenges for developing countries that may be overcome with better communication; global collaborations and partnerships for leveraging investments and enable uninterrupted supply of affordable and suitable vaccines; and leading innovation in vaccines difficult to develop, such as dengue, Chikungunya, typhoid-conjugated and EV71, and needle-free technologies that may speed up vaccine delivery. Moving further into the Decade of Vaccines, participants renewed their commitment to shared responsibility toward a world free of vaccine-preventable diseases. Copyright © 2015 The Authors.

Job Satisfaction and Organizational Commitment: Affective Commitment Predictors in a Group of Professionals

Science.gov (United States)

Ferretti, Maria Santa

Job satisfaction and organizational commitment have long been identified as relevant factors for the well-being of individuals within an organization and the success of the organization itself. As the well-being can be, in principle, considered as emergent from the influence of a number of factors, the main goal of a theory of organizations is to identify these factors and the role they can play. In this regard job satisfaction and organizational commitment have been often identified with structural factors allowing an organization to be considered as a system, or a wholistic entity, rather than a simple aggregate of individuals. Furthermore, recent studies have shown that job satisfaction has a significant, direct effect on determining individuals' attachment to an organization and a significant but indirect effect on their intention to leave a company. However, a complete assessment of the role of these factors in establishing and keeping the emergence of an organization is still lacking, due to shortage of measuring instruments and to practical difficulties in interviewing organization members. The present study aims to give a further contribution to what is currently known about the relationship between job satisfaction and affective commitment by using a group of professionals, all at management level. A questionnaire to measure these constructs, following a pilot study, was designed and administered to 1042 participants who were all professionals and had the title of industrial manager or director. The factors relating to job satisfaction and the predictive value of these factors (to predict an employee's emotional involvement with their organization) were simultaneously tested by a confirmative factorial model. The results were generalized with a multi-sample procedure by using models of structural equations. This procedure was used to check whether these factors could be considered or not as causes producing the measured affective commitment. The results

The Impact of Trust on Organization Commitment

Science.gov (United States)

Robinson, Kimberly; Stinson, Thomas N. (Technical Monitor)

2002-01-01

As the global economy continues to spawn competitive forces, organizations have sought to become more competitive by cutting costs, eliminating non-value added work, and using more automation. Jobs have become broader and more flexible leading to a leaner workforce with higher-level knowledge and skills and more responsibility for day-to-day decisions. More than ever, organizations depend on employees as the innovators and designers of products and processes and as a source of strategic advantage. Therefore employee commitment among knowledge workers is needed to maintain organizational viability. It would seem that stronger relationships due to greater dependency, involvement, and investment would develop between employers and high-technology workers resulting in more committed employees. However, the opposite has been evidenced as key knowledge workers are changing jobs frequently. This may be due to a perceived lack of commitment by management to its employees. The notion of exchange may dominate the development of organizational commitment whereby an individual decides what to give a firm (commitment, extra effort, better performance, etc.) based on what the firm gives them (e.g., trust and security). It is the relationship between an employee's organizational commitment and the responding level of trust in the organization that is examined in this paper. An experiment is described that will seek to identify this relationship. Preliminary results are expected to show a positive relationship whereby employee commitment is positively correlated with organizational trust.

Model to estimate radiation dose commitments to the world population from the atmospheric release of radionuclides (LWBR development program)

Rider, J.L.; Beal, S.K.

1978-02-01

The equations developed for use in the LWBR environmental statement to estimate the dose commitment over a given time interval to a given organ of the population in the entire region affected by the atmospheric releases of a radionuclide are presented and may be used for any assessment of dose commitments in these regions. These equations define the dose commitments to the world resulting from a released radionuclide and each of its daughters and the sum of these dose commitments provides the total dose commitment accrued from the release of a given radionuclide. If more than one radionuclide is released from a facility, then the sum of the dose commitments from each released nuclide and from each daughter of each released nuclide is the total dose commitment to the world from that facility. Furthermore, if more than one facility is considered as part of an industry, then the sum of the dose commitments from the individual facilities represents the total world dose commitment associated with that industry. The actual solutions to these equations are carried out by the AIRWAY computer program. The writing of this computer program entailed defining in detail the specific representations of the various parameters such as scavenging coefficients, resuspension factors, deposition velocities, dose commitment conversion factors, and food uptake factors, in addition to providing specific numerical values for these types of parameters. The program permits the examination of more than one released nuclide at a time and performs the necessary summing to obtain the total dose commitment to the world accrued from the specified releases

A storage-based model of heterocyst commitment and patterning in cyanobacteria

International Nuclear Information System (INIS)

Brown, Aidan I; Rutenberg, Andrew D

2014-01-01

When deprived of fixed nitrogen (fN), certain filamentous cyanobacteria differentiate nitrogen-fixing heterocysts. There is a large and dynamic fraction of stored fN in cyanobacterial cells, but its role in directing heterocyst commitment has not been identified. We present an integrated computational model of fN transport, cellular growth, and heterocyst commitment for filamentous cyanobacteria. By including fN storage proportional to cell length, but without any explicit cell-cycle effect, we are able to recover a broad and late range of heterocyst commitment times and we observe a strong indirect cell-cycle effect. We propose that fN storage is an important component of heterocyst commitment and patterning in filamentous cyanobacteria. The model allows us to explore both initial and steady-state heterocyst patterns. The developmental model is hierarchical after initial commitment: our only source of stochasticity is observed growth rate variability. Explicit lateral inhibition allows us to examine ΔpatS, ΔhetN, and ΔpatN phenotypes. We find that ΔpatS leads to adjacent heterocysts of the same generation, while ΔhetN leads to adjacent heterocysts only of different generations. With a shortened inhibition range, heterocyst spacing distributions are similar to those in experimental ΔpatN systems. Step-down to non-zero external fN concentrations is also investigated. (paper)

This paper discusses how New York's approach to developing a new low-level radioactive waste disposal facility demonstrates a commitment to responsibility for waste generated within its borders. There is a strong, legislated commitment to meeting federal milestones and starting from scratch to select a suitable site and disposal method. Equally strong is the state's commitment to meaningful public participation. A statewide program is underway, including public information and education and interactive techniques. The public participation program is fully integrated with the technical and policy activities of the New York State Low-Level Radioactive Waste Siting Commission at all levels. The program is designed to progressively tailor techniques and coverage to the steps in site and method selection, and will focus most intensively on the communities where four sites are selected for full characterization

The study is to check the specialty of radiotherapists working in the department of radiation oncology and find job satisfaction, organizational commitment and job commitment having an effect on professional parts. After making analysis of the mutual relation, it is to provide radiotechnologists with making progress in the future. From March 2 to March 30, we had carried out a survey with email. It is possible to have 272 questionnaires answered in the survey. We make use of SPSS 13.0 for Windows to analyze the data collected for study. Frequency and a percentage are meant to show general characteristics, and t-test and ANOVA to do the difference between general properties and professionalism. Pearson's correlation coefficient also is meant to do the correlation of professionalism, organizational job commitment and job satisfaction, and multiple regression analysis to do the factor for a relevant variable to affect professionalism. There are subdivisions in the professionalism informing us of the self-regulation 17.74{+-}2.32/3.55{+-}46, a sense of calling 17.58{+-}2.63/3.52{+-}53, reference of the professional 17.14{+-}2.39/3.43{+-}48, service to the public 15.97{+-}2.48/3.19{+-}50, and autonomy 15.68{+-}2.28/3.14{+-}46.

Full Text Available During the past few years, organizational commitment has been a major concern in different types of business activities including banking industry. In this paper, we present an empirical investigation to study the relationship between social entrepreneurship and organizational commitment. The proposed study of this paper adapts a standard questionnaire developed by Meyer and Allen [Meyer, J. P., & Allen, N. J. (1991. A three-component conceptualization of organizational commitment. Human resource management review, 1(1, 61-89]. Cronbach alpha has been calculated for affective commitment, employee engagement and normative commitment as 0.77, 0.79 and 0.61, respectively. The results of survey indicate that affective commitment, employee engagement and normative commitment have positively influenced organizational commitment, significantly. In addition, Freedman test has indicated that normative commitment is number one priority with mean rank of 2.85 followed by affective commitment with mean rank of 2.47 and employee engagement with the mean rank of 2.26.

​​​The current study examined the influence of social identity for individual perceptions of self-worth, commitment, and effort in school-based youth athletes. Using a prospective research design, 303 athletes (M age  = 14.89, SD = 1.77; 133 female) from 27 sport teams completed questionnaires at 2 time points (T1 - demographics, social identity; T2 - self-worth, commitment, effort) during an athletic season. Multilevel analyses indicated that at the individual level, the social identity dimension of in-group ties (IGT) predicted commitment (b = 0.12, P = .006) and perceived effort (b = 0.14, P = .008), whereas in-group affect (IGA) predicted commitment (b = 0.25, P = .001) and self-worth (b = 2.62, P = .006). At the team level, means for IGT predicted commitment (b = 0.31, P < .001) and self-worth (b = 4.76, P = .024). Overall, social identity accounted for variance at both levels, ranging from 4% (self-worth) to 15% (commitment). Identifying with a group to a greater extent was found to predict athlete perceptions of self-worth, commitment, and effort. More specifically, at the individual level, IGT predicted commitment and effort, and IGA predicted commitment and self-worth. At the team level, IGT predicted commitment and self-worth.

The aim of this study was to explore the correlation of hope and self-efficacy with job satisfaction, job stress, and organizational commitment for correctional officers in the Taiwan prison system while controlling for the shared effects of the nature of the institution (i.e., for male or female inmates) and personal characteristics of the officers (i.e., gender, age, and years of work experience). Hope in the context of this study refers to a cognitive set and motivational state that involves reciprocal interaction between goal-directed energy (agency) and planned pathways to meet the goals (pathway). It is a personality trait of hopefulness, rather than having hope for the prisoners restructuring their future. Self-efficacy refers to the belief that individuals have regarding their ability to perform necessary tasks to achieve goals. Although they share similar constructs, hope theory places emphasis on cross-situational goal-directed thought, whereas the concept of self-efficacy focuses on situation-specific goals. The participants were 133 correctional personnel from two correctional institutions, one with male inmates and the other with female inmates, in central Taiwan. The results of ordinary least squares regression analysis indicated that hope had a significant positive association with job satisfaction and a significant negative association with job stress. Self-efficacy had a significant positive association with job satisfaction and organizational commitment. Finally, job satisfaction had a significant positive association with organizational commitment. © The Author(s) 2015.

One-way shared memory

Standard multicore processors use the shared main memory via the on-chip caches for communication between cores. However, this form of communication has two limitations: (1) it is hardly time-predictable and therefore not a good solution for real-time systems and (2) this single shared memory...... is a bottleneck in the system. This paper presents a communication architecture for time-predictable multicore systems where core-local memories are distributed on the chip. A network-on-chip constantly copies data from a sender core-local memory to a receiver core-local memory. As this copying is performed...... in one direction we call this architecture a one-way shared memory. With the use of time-division multiplexing for the memory accesses and the network-on-chip routers we achieve a time-predictable solution where the communication latency and bandwidth can be bounded.

Hallam, Larissa

2007-08-01

Little research has examined how, or if, involuntary commitment has impacted on the burden experienced by the family. This paper reports a qualitative study which explored how involuntary commitment under the Mental Health Act (MHA) 2000 in Queensland, Australia impacted on families of people with mental illness. Family members of a person with a mental illness, under involuntary commitment at the time or in the previous 12 months, participated in focus groups. Thematic analysis was used to determine the themes. It was apparent from the views of the family that the use of the involuntary commitment was influenced greatly by the pressures experienced by the mental health services (MHS). The MHA did little to assist the family in gaining access to MHS. It was not until after the family made repeated attempts that they were taken seriously. Often the family had few options other than to use deceit and threats to obtain the necessary treatment required. In view of this, the inherit nature of what involuntary commitment implies for persons under it, such as refusing treatment and management difficulties, indicates the family with such an individual experience more hardship in trying to obtain assistance for that person. Thus, the MHA in Queensland has not met its goals of increasing access to MHS. Family members perceive that they were not being listened to and their concerns were not acted upon. The current culture of the MHS appears to serve, to a large degree, to estrange the family from the consumer making relationships difficult and time-consuming to repair. The mental health profession is urged to consider the culture within their workplace and move towards constructive involvement of the family.

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 Philanthropic commitment in the form of waqf is important particularly among younger working adults in ensuring sustainable flow of funds for charitable purposes. One of the vital usages of such funds is funding for higher education. A question is raised on the commitment of younger adults in such giving. This study examines waqf commitment traits among waqif (waqf contributors for higher education funding. The specific objective of this study is to measure the factors that influence the waqif to contribute their property or income into waqf for higher education fund. For the purpose of this study, 400 questionnaires have been distributed to working young adult respondents in the Klang Valley area. Waqf commitment attributes comprising of Religiosity, Trust, Altruism, Personal Characteristics, SelfImage, Psychological Benefits, Social Norms and Personal Satisfaction are examined. The findings reveal that Religiosity, Altruism, Personal Satisfaction and Commitment are significant attributes in explaining waqf commitment. However, Trust and Social Norm are not significant.

Full Text Available This study aims to examine the effect of government internal auditors moral levels and situational pressures on the tendency to commit fraud when conducting audit. Based on the hypothesis, despite the situational pressures, the government internal auditors who have a high moral level will not commit fraud at the time of auditing. Meanwhile, the government internal auditors who have a low moral level will com-mit fraud at the time of auditing when there is situational pressure. To test the hypothesis, a 22 factorial experiment is conducted involving 68 students of STAR-BPKP of Jenderal Soedirman University. The results indicate that the government internal auditors who have a high moral level will not commit fraud in the time of auditing despite some situational pressures. Meanwhile, the government internal auditors who have a low moral level will commit fraud at the time of auditing either there is a situational pressure or not. The implications of this study are to streng-then the supervisory system for the internal auditors at the time of auditing, to provide protection for whistle- blowers who report the presence of fraud committed by auditors, and to be consistent in giving reward to professional auditors and pu-nishment to auditors who are convicted of fraud at the time of auditing.

Voice, (inter-)subjectivity, and real time recurrent interaction.

Cummins, Fred

2014-01-01

Received approaches to a unified phenomenon called "language" are firmly committed to a Cartesian view of distinct unobservable minds. Questioning this commitment leads us to recognize that the boundaries conventionally separating the linguistic from the non-linguistic can appear arbitrary, omitting much that is regularly present during vocal communication. The thesis is put forward that uttering, or voicing, is a much older phenomenon than the formal structures studied by the linguist, and that the voice has found elaborations and codifications in other domains too, such as in systems of ritual and rite. Voice, it is suggested, necessarily gives rise to a temporally bound subjectivity, whether it is in inner speech (Descartes' "cogito"), in conversation, or in the synchronized utterances of collective speech found in prayer, protest, and sports arenas world wide. The notion of a fleeting subjective pole tied to dynamically entwined participants who exert reciprocal influence upon each other in real time provides an insightful way to understand notions of common ground, or socially shared cognition. It suggests that the remarkable capacity to construct a shared world that is so characteristic of Homo sapiens may be grounded in this ability to become dynamically entangled as seen, e.g., in the centrality of joint attention in human interaction. Empirical evidence of dynamic entanglement in joint speaking is found in behavioral and neuroimaging studies. A convergent theoretical vocabulary is now available in the concept of participatory sense-making, leading to the development of a rich scientific agenda liberated from a stifling metaphysics that obscures, rather than illuminates, the means by which we come to inhabit a shared world.

Chappas, W.J.; Adams, V.G.

1998-01-01

The Department of Energy University Reactor Sharing Program at University of Maryland, College Park (UMCP) has, once again, stimulated a broad use of the reactor and radiation facilities by undergraduate and graduate students, visitors, and professionals. Participants are exposed to topics such as nuclear engineering, radiation safety, and nuclear reactor operations. This information is presented through various means including tours, slide presentations, experiments, and discussions. Student research using the MUTR is also encouraged. In addition, the Reactor Sharing Program here at the University of Maryland does not limit itself to the confines of the TRIGA reactor facility. Incorporated in the program are the Maryland University Radiation Effects Laboratory, and the UMCP 2 x 4 Thermal Hydraulic Loop. These facilities enhance and give an added dimension to the tours and experiments. The Maryland University Training Reactor (MUTR) and the associated laboratories are made available to any interested institution six days a week on a scheduled basis. Most institutions are scheduled at the time of their first request--a reflection of their commitment to the Reactor Sharing Program. The success of the past years by no means guarantees future success. Therefore, the reactor staff is more aggressively pursuing its outreach program, especially with junior colleges and universities without reactor or radiation facilities; more aggressively developing demonstration and training programs for students interested in careers in nuclear power and radiation technology; and more aggressively up-grading the reactor facilities--not only to provide a better training facility but to prepare for relicensing in the year 2000

Building upon Deci's and Ryan (1985) Self-determination theory as well as the sportive behavioral correlates of the model of Commitment (Scanlan et al., 1976), this study tries to establish the relationship between motivation and commitment in youth sport. For this purpose 454 young competitive soccer players answered the Sport Motivation Scale (SMS) and the Sport Commitment Questionnaire (SCQ) during the regular season. The SMS measures the three dimensions of the Motivational continuum (the Amotivation, the Extrinsic Motivation and the Intrinsic Motivation). The SCQ measures the Sportive Commitment and its composing factors such as the Enjoyment, the Alternatives to the sport, and the Social Pressure. Our findings provided a clear pattern of the influence of motivation in sport enjoyment and commitment, outlining the positive contribution of intrinsic and extrinsic motivation to enjoyment and commitment. Amotivation, contributes positively to alternatives to sport and negatively to enjoyment and commitment, It should be noted that extrinsic motivation has a higher contribution to enjoyment whereas intrinsic motivation has a higher contribution to commitment.

Full Text Available The study of employee’s commitment is capturing the attention of managers and researchers. Besides being one of the most effective alternatives for achieving the organizational goals, the importance of organizational commitment (OC lies in its ability to influence the efficiency and the wellbeing of members of an organization. The article examines the relationships between personal values and components of OC. Participants were selected from twelve Argentinean organizations. Subjects completed a questionnaire of personal data, and two scales to measure individualism- collectivism (vertical and horizontal, and organizational commitment, respectively. All subjects were classified into eight subgroups, after dichotomizing by median each dimensions of values (HI: horizontal individualism; VI: vertical individualism; HC: horizontal collectivism, and HV: vertical collectivism. The four most representative subgroups (N= 162 were selected, that is, who exhibited high scores in one of the four dimensions and lows in the remaining three. In such subgroups were calculated analysis of variance, post-hoc comparison tests, and correlation analysis. The more significant findings can be summarized in the following items: a collectivists (HC or VC show a higher level of affective commitment, while individualists relate to their companies through normative or continuance commitment; b women and senior employees exhibit greater levels of affective and normative commitment; c managers, employees with higher academic degree, and employees of large companies, feel attached to their organizations through normative commitment; d continuance commitment seems to work differently than affective and normative commitment because it has no associations with any of the socio-demographic variables studied. Strengths and limitations of the study are discussed, and suggestions are made for future research. 

Factors Contributing to Personal Commitment in Chinese Interethnic Couples

Full Text Available Interethnic relationships are increasingly common in many societies, yet interethnic couples have a higher divorce rate compared to intraethnic couples. Given these facts and the dearth of research, this study aimed to identify factors that contribute to couples’ commitment in interethnic relationships. This study investigated the personal commitment of Chinese interethnic couples in the United Kingdom and the United States. Specifically, whether love, dyadic adjustment and “couple cultural identity” (i.e. acculturation to the partner and couple’s similarity on individualism/collectivism would predict personal commitment and whether each variable would account for unique variance in personal commitment of the participants. Thirty-seven Chinese/non-Chinese heterosexual couples participated in the study and significant relationships between love and personal commitment, dyadic adjustment and personal commitment were found. Also, couple cultural identity was important for women’s personal commitment. Multiple regression and structural equation modelling showed that partners in interethnic relationships defined personal commitment in different ways with men emphasizing love and dyadic adjustment, and women emphasizing love and acculturation to their partner. The discovery of the importance of couple cultural identity in contributing to personal commitment, besides love and dyadic adjustment, helps researchers to gain a greater understanding of such relationships and to extend the research on interethnic relationships.

Time to consider sharing data extracted from trials included in systematic reviews

Full Text Available Abstract Background While the debate regarding shared clinical trial data has shifted from whether such data should be shared to how this is best achieved, the sharing of data collected as part of systematic reviews has received little attention. In this commentary, we discuss the potential benefits of coordinated efforts to share data collected as part of systematic reviews. Main body There are a number of potential benefits of systematic review data sharing. Shared information and data obtained as part of the systematic review process may reduce unnecessary duplication, reduce demand on trialist to service repeated requests from reviewers for data, and improve the quality and efficiency of future reviews. Sharing also facilitates research to improve clinical trial and systematic review methods and supports additional analyses to address secondary research questions. While concerns regarding appropriate use of data, costs, or the academic return for original review authors may impede more open access to information extracted as part of systematic reviews, many of these issues are being addressed, and infrastructure to enable greater access to such information is being developed. Conclusion Embracing systems to enable more open access to systematic review data has considerable potential to maximise the benefits of research investment in undertaking systematic reviews.

The purpose of this study was to examine the impact of selected organizational factors and the leadership behavior of supervisors on radiation therapists' commitment to their organizations. The population for this study consists of all full time clinical radiation therapists registered by the American Registry of Radiologic Technologists (ARRT) in the United States. A random sample of 800 radiation therapists was obtained from the ARRT for this study. Questionnaires were mailed to all participants and measured organizational variables; managerial leadership variable and three components of organizational commitment (affective, continuance and normative). It was determined that organizational support, and leadership behavior of supervisors each had a significant and positive affect on normative and affective commitment of radiation therapists and each of the models predicted over 40% of the variance in radiation therapists organizational commitment. This study examined radiation therapists' commitment to their organizations and found that affective (emotional attachment to the organization) and normative (feelings of obligation to the organization) commitments were more important than continuance commitment (awareness of the costs of leaving the organization). This study can help radiation oncology administrators and physicians to understand the values their radiation therapy employees hold that are predictive of their commitment to the organization. A crucial result of the study is the importance of the perceived support of the organization and the leadership skills of managers/supervisors on radiation therapists' commitment to the organization.

Multicore processors usually communicate via shared memory, which is backed up by a shared level 2 cache and a cache coherence protocol. However, this solution is not a good fit for real-time systems, where we need to provide tight guarantees on execution and memory access times. In this paper, we...... propose a shared scratchpad memory as a time-predictable communication and synchronization structure, instead of the level 2 cache. The shared on-chip memory is accessed via a time division multiplexing arbiter, isolating the execution time of load and store instructions between processing cores....... Furthermore, the arbiter supports an extended time slot where an atomic load and store instruction can be executed to implement synchronization primitives. In the evaluation we show that a shared scratchpad memory is an efficient communication structure for a small number of processors; in our setup, 9 cores...

Finally, we show that our strong RSA based construction can be used to improve the most efficient known UC commitment scheme so it can work with a CRS of size independent of the number of players, without loss of efficiency....

Quantum secret sharing based on modulated high-dimensional time-bin entanglement

International Nuclear Information System (INIS)

Takesue, Hiroki; Inoue, Kyo

2006-01-01

We propose a scheme for quantum secret sharing (QSS) that uses a modulated high-dimensional time-bin entanglement. By modulating the relative phase randomly by {0,π}, a sender with the entanglement source can randomly change the sign of the correlation of the measurement outcomes obtained by two distant recipients. The two recipients must cooperate if they are to obtain the sign of the correlation, which is used as a secret key. We show that our scheme is secure against intercept-and-resend (IR) and beam splitting attacks by an outside eavesdropper thanks to the nonorthogonality of high-dimensional time-bin entangled states. We also show that a cheating attempt based on an IR attack by one of the recipients can be detected by changing the dimension of the time-bin entanglement randomly and inserting two 'vacant' slots between the packets. Then, cheating attempts can be detected by monitoring the count rate in the vacant slots. The proposed scheme has better experimental feasibility than previously proposed entanglement-based QSS schemes

Background Violence that leads to homicide results in an extreme financial and emotional burden on society. Juveniles who commit homicide are often tried in adult court and typically spend the majority of their lives in prison. Despite the enormous costs associated with homicidal behavior, there have been no serious neuroscientific studies examining youth who commit homicide. Methods Here we use neuroimaging and voxel-based morphometry to examine brain gray matter in incarcerated male adolescents who committed homicide (n = 20) compared with incarcerated offenders who did not commit homicide (n = 135). Two additional control groups were used to understand further the nature of gray matter differences: incarcerated offenders who did not commit homicide matched on important demographic and psychometric variables (n = 20) and healthy participants from the community (n = 21). Results Compared with incarcerated adolescents who did not commit homicide (n = 135), incarcerated homicide offenders had reduced gray matter volumes in the medial and lateral temporal lobes, including the hippocampus and posterior insula. Feature selection and support vector machine learning classified offenders into the homicide and non-homicide groups with 81% overall accuracy. Conclusions Our results indicate that brain structural differences may help identify those at the highest risk for committing serious violent offenses. PMID:24936430

Caregivers' commitment to personal values is linked to caregivers' well-being, although the effects of personal values on caregivers' guilt have not been explored to date. The goal of this study is to analyze the relationship between caregivers´ commitment to personal values and guilt feelings. Participants were 179 dementia family caregivers. Face-to-face interviews were carried out to describe sociodemographic variables and assess stressors, caregivers' commitment to personal values and guilt feelings. Commitment to values was conceptualized as two factors (commitment to own values and commitment to family values) and 12 specific individual values (e.g. education, family or caregiving role). Hierarchical regressions were performed controlling for sociodemographic variables and stressors, and introducing the two commitment factors (in a first regression) or the commitment to individual/specific values (in a second regression) as predictors of guilt. In terms of the commitment to values factors, the analyzed regression model explained 21% of the variance of guilt feelings. Only the factor commitment to family values contributed significantly to the model, explaining 7% of variance. With regard to the regression analyzing the contribution of specific values to caregivers' guilt, commitment to the caregiving role and with leisure contributed negatively and significantly to the explanation of caregivers' guilt. Commitment to work contributed positively to guilt feelings. The full model explained 30% of guilt feelings variance. The specific values explained 16% of the variance. Our findings suggest that commitment to personal values is a relevant variable to understand guilt feelings in caregivers.

This paper presents the Time Shared Optical Network (TSON) as metro mesh network architecture for guaranteed, statistically-multiplexed services. TSON proposes a flexible and tunable time-wavelength assignment along with one-way tree-based reservation and node architecture. It delivers guaranteed sub-wavelength and multi-granular network services without wavelength conversion, time-slice interchange and optical buffering. Simulation results demonstrate high network utilization, fast service delivery, and low end-to-end delay on a contention-free sub-wavelength optical transport network. In addition, implementation complexity in terms of Layer 2 aggregation, grooming and optical switching has been evaluated. © 2011 Optical Society of America

Full Text Available The prevalence of civil disorder and cultism in higher institutions of learning in Nigeria and the apparent inability of security operatives to stem the tide has continued to be a source of concern to both the Government and Individuals in recent times. This study examines the effect of organisational commitment on job satisfaction among security operatives working in Nigeria universities. In this study a sample of three hundred (300 security operatives were selected from both public and private universities in Kwara State. Data were collected through self-administered questionnaire and analysed through Descriptive, Comparative, Regression analysis and Spearman Rank Correlation. The findings revealed that these security operatives, a positive relationship exists between organisational commitment and job satisfaction with affective commitment having little or no significant relationship and continuance commitment having significant positive relationship. The study also found that the level of affective commitment was significantly lower than the other components. The study thus concludes that there is a significant positive relationship between organisation commitment and job satisfaction amongst the security operatives. Based on the findings, it was recommended that the selected Universities should focus on improving affective and normative commitment among security operatives in order to be able to deal with the problem of high job turnover and poor performance.

Full Text Available Background: The employees' satisfaction from their job and their commitment to the organization appears to be one of the most determinants factors of organizational effectiveness.Aim: The aim of this study was the research of commitment to the organization of employees' working at Sparta General Hospital, as well as the correlation between job satisfaction and social, economic, demographic or other factors.Methodology: The research’s sample included 121 employees from all departments of a public district hospital. For research purposes, the Organizational Commitment Questionnaire was used. Data specially designed for the research’s purposes.Results: The largest sample’s proportion, declared moderate to very satisfy by their job at that Hospital. The particular job demands, exhausting timetables, stress and organizational weaknesses of the Greek Health System seem to have been key components of the problem. Also, for a large sample proportion, the job demands affect negatively the time and energy that Sparta General Hospital employees’ dedicate to themselves and to their families. Almost half of the participants replied that they are not at all satisfied with their payroll. Regarding the rates of emotional, standing and exemplary commitment, showed that gender, education level, marital status, age and total years of professional seniority correlated with the level of emotional commitment. To higher affective commitment is positively correlated with age of employees and years of service.Conclusions: The research of commitment to the organization can contribute substantially in improving the hospital’s and health system’s effectiveness, the increment of job’s satisfaction, the employees’ efficiency.

Population dose commitments due to radioactive releases from nuclear power plant sites in 1987

International Nuclear Information System (INIS)

Baker, D.A.

1990-08-01

Population radiation dose commitments have been estimated from reported radionuclide releases from commercial power reactors operating during 1987. Fifty-year dose commitments for a one-year exposure from both liquid and atmospheric releases were calculated for four population groups (infant, child, teen-ager and adult) residing between 2 and 80 km from each of 70 reactor sites. This report tabulates the results of these calculations, showing the dose commitments for both water and airborne pathways for each age group and organ. Also included for reach of the sites is a histogram showing the fraction of the total population within 2 to 80 km around each site receiving various average dose commitments from the airborne pathways. The site average individual dose commitment from all pathways ranged from a low of 2 x 10 -6 mrem to a high of 0.009 mrem. No attempt was made in this study to determine the maximum dose commitment received by any one individual from the radionuclides released at any of the sites. However, licensee calculation of doses to the maximally exposed individual at some sites indicated values of up to approximately 100 times average individual doses (on the order of a few millirem per year). 2 refs., 2 figs., 7 tabs

Introduction: Time-resolved contrast-enhanced magnetic resonance (MR) angiography (CEMRA) of the intracranial vasculature has proved its clinical value for the evaluation of cerebral vascular disease in cases where both flow hemodynamics and morphology are important. The purpose of this study was to evaluate a combination of view-sharing with keyhole imaging to increase spatial and temporal resolution of time-resolved CEMRA at 3.0 T. Methods: Alternating view-sharing was combined with randomly segmented k-space ordering, keyhole imaging, partial Fourier and parallel imaging (4DkvsMRA). 4DkvsMRA was evaluated using varying compression factors (80-100) resulting in spatial resolutions ranging from (1.1 x 1.1 x 1.4) to (0.96 x 0.96 x 0.95) mm 3 and temporal resolutions ranging from 586 ms/dynamic scan - 288 ms/dynamic scan in three protocols in 10 healthy volunteers and seven patients (17 subjects). DSA correlation was available in four patients with cerebral arteriovenous malformations (cAVMs) and one patient with cerebral teleangiectasia. Results: 4DkvsMRA was successfully performed in all subjects and showed clear depiction of arterial and venous phases with diagnostic image quality. At the maximum view-sharing compression factor (=100), a 'flickering' artefact was observed. Conclusion: View-sharing in keyhole imaging allows for increased spatial and temporal resolution in time-resolved MRA.

The practice of sustainable facilities management (FM) is rapidly evolving with the increasing interest in the discourse of sustainable development. This paper examines a recent survey of the experiences of facilities managers in the rapidly growing and evolving industry in regard to the barriers and their commitment to the sustainability agenda. The survey results show that time constraints, lack of knowledge and lack of senior management commitment are the main barriers for the implementation of consistent and comprehensive sustainable FM policy and practice. The paper concludes that the diversity of the FM role and the traditional undervaluation of the contribution it makes to the success of organisations are partially responsible for lack of success in achieving sustainable facilities. The overwhelming barrier for sustainable FM practice is the lack of understanding, focus and commitment of senior executives in appreciating the opportunities, threats and need for strategic leadership and direction in driving essential change, and hence further the sustainability agenda.

Also included for each of the sites is a histogram showing the fraction of the total population within 2 to 80 km around each site receiving various average dose commitments from the airborne pathways. The total dose commitments (from both liquid and airborne pathways) for each site ranged from a high of 73 person-rem to a low of 0.011 person-rem for the sites with plants operating throughout the year with an arithmetic mean of 3 person-rem. The total population dose for all sites was estimated at 200 person-rem for the 110 million people considered at risk. The site average individual dose commitment from all pathways ranged from a low of 5 /times/ 10/sup /minus/6/ mrem to a high of 0.02 mrem.

A Comprehensive Optimization Strategy for Real-time Spatial Feature Sharing and Visual Analytics in Cyberinfrastructure

Science.gov (United States)

Li, W.; Shao, H.

2017-12-01

For geospatial cyberinfrastructure enabled web services, the ability of rapidly transmitting and sharing spatial data over the Internet plays a critical role to meet the demands of real-time change detection, response and decision-making. Especially for the vector datasets which serve as irreplaceable and concrete material in data-driven geospatial applications, their rich geometry and property information facilitates the development of interactive, efficient and intelligent data analysis and visualization applications. However, the big-data issues of vector datasets have hindered their wide adoption in web services. In this research, we propose a comprehensive optimization strategy to enhance the performance of vector data transmitting and processing. This strategy combines: 1) pre- and on-the-fly generalization, which automatically determines proper simplification level through the introduction of appropriate distance tolerance (ADT) to meet various visualization requirements, and at the same time speed up simplification efficiency; 2) a progressive attribute transmission method to reduce data size and therefore the service response time; 3) compressed data transmission and dynamic adoption of a compression method to maximize the service efficiency under different computing and network environments. A cyberinfrastructure web portal was developed for implementing the proposed technologies. After applying our optimization strategies, substantial performance enhancement is achieved. We expect this work to widen the use of web service providing vector data to support real-time spatial feature sharing, visual analytics and decision-making.

Meaningful Share Generation for Increased Number of Secrets in Visual Secret-Sharing Scheme

Directory of Open Access Journals (Sweden)

Mustafa Ulutas

2010-01-01

Full Text Available This paper presents a new scheme for hiding two halftone secret images into two meaningful shares created from halftone cover images. Meaningful shares are more desirable than noise-like (meaningless shares in Visual Secret Sharing because they look natural and do not attract eavesdroppers' attention. Previous works in the field focus on either increasing number of secrets or creating meaningful shares for one secret image. The method outlined in this paper both increases the number of secrets and creates meaningful shares at the same time. While the contrast ratio of shares is equal to that of Extended Visual Cryptography, two secrets are encoded into two shares as opposed to one secret in the Extended Visual Cryptography. Any two natural-looking images can be used as cover unlike the Halftone Visual Cryptography method where one cover should be the negative of the other cover image and can only encode one secret. Effectiveness of the proposed method is verified by an experiment.

On Commitments and Other Uncertainty Reduction Tools in Joint Action

Directory of Open Access Journals (Sweden)

Michael John

2015-01-01

Full Text Available In this paper, we evaluate the proposal that a central function of commitments within joint action is to reduce various kinds of uncertainty, and that this accounts for the prevalence of commitments in joint action. While this idea is prima facie attractive, we argue that it faces two serious problems. First, commitments can only reduce uncertainty if they are credible, and accounting for the credibility of commitments proves not to be straightforward. Second, there are many other ways in which uncertainty is commonly reduced within joint actions, which raises the possibility that commitments may be superfluous. Nevertheless, we argue that the existence of these alternative uncertainty reduction processes does not make commitments superfluous after all but, rather, helps to explain how commitments may contribute in various ways to uncertainty reduction.

2012-01-01

Aim: Professional commitment has been widely discussed during the last decade. There is no comprehensive definition about “professional commitment in Iranian nurses.” Hence, this study was conducted with the aim of analyzing the concept of professional commitment in Iranian nurses. Materials and Methods: Hybrid model was used in three phases. Firstly, in the theoretical phase, data were retrieved from the CINHAl, MEDLINE, PubMed, OVID, Google scholar, and SID databases. The literature search used the keywords “professional commitment” and “nursing.” The final sample included 27 papers published in English between 2001 and 2011.Secondly, in the fieldwork phase, deep interviews with five clinical nurses were carried out, and thirdly, in the final analytical phase, the obtained data from theoretical and fieldwork phases were combined and a comprehensive analysis was conducted. Results: Loyalty and tendency to remain in the profession and responsibility to the professional issues were extracted in theoretical phase. Commitment to promote caring abilities, satisfying of being a nurse, and belonging to the nursing profession were obtained in fieldwork phase. Finally, two main themes including “commitment to offering the best nursing care” and “commitment to promotion of the nursing profession” were extracted. Conclusion: Nursing is a humanistic profession; it has some particular characteristics due to the profession’s nature. In this paper, a definition composed of two main dimensions of professional commitment in nursing has been introduced. PMID:23922592

The organizational commitment of emergency physicians in Spanish public hospitals

Noval de la Torre, A; Bulchand Gidumal, J; Melián González, S

2016-12-30

Background. There are not too many studies that deal with the organizational commitment of emergency physicians. This commitment has been shown to impact organizational performance. The aim of this paper is to analyse the degree of commitment of the emergency physicians in Spanish public hospitals and the factors that may influence it. Method. Online survey using SurveyMonkey to emergency physicians in Spanish public hospitals. Results. Two hundred and five questionnaires were received, 162 from physicians and 43 from heads of the emergency service. Results show an intermediate level of commitment, with affective commitment showing the lowest level and continuance commitment showing the highest level. The capabilities of the physician have an influence on their affective commitment; specific training in emergency procedures and seniority has an influence on their continuance commitment; and the opinion they hold about the organization of their service influences affective commitment. Conclusions. Emergency physicians show an average involvement in the hospital in which they work (average 3.8 on a range of 1 to 5), feel an average affection for it (3.4), and have a high intention to keep working there (4.0). The resources the hospital has due to its level do not have an influence on this commitment, while the training and perceptions of the service do have an influence.

Sardanelli, Francesco; Alì, Marco; Hunink, Myriam G; Houssami, Nehmat; Sconfienza, Luca M; Di Leo, Giovanni

2018-06-01

The aims of this paper are to illustrate the trend towards data sharing, i.e. the regulated availability of the original patient-level data obtained during a study, and to discuss the expected advantages (pros) and disadvantages (cons) of data sharing in radiological research. Expected pros include the potential for verification of original results with alternative or supplementary analyses (including estimation of reproducibility), advancement of knowledge by providing new results by testing new hypotheses (not explored by the original authors) on pre-existing databases, larger scale analyses based on individual-patient data, enhanced multidisciplinary cooperation, reduced publication of false studies, improved clinical practice, and reduced cost and time for clinical research. Expected cons are outlined as the risk that the original authors could not exploit the entire potential of the data they obtained, possible failures in patients' privacy protection, technical barriers such as the lack of standard formats, and possible data misinterpretation. Finally, open issues regarding data ownership, the role of individual patients, advocacy groups and funding institutions in decision making about sharing of data and images are discussed. • Regulated availability of patient-level data of published clinical studies (data-sharing) is expected. • Expected benefits include verification/advancement of knowledge, reduced cost/time of research, clinical improvement. • Potential drawbacks include faults in patients' identity protection and data misinterpretation.

Defining progressive stages in the commitment process leading to embryonic lens formation

Jin, Hong; Fisher, Marilyn; Grainger, Robert M.

2013-01-01

Summary The commitment of regions of the embryo to form particular tissues or organs is a central concept in development, but the mechanisms controlling this process remain elusive. The well-studied model of lens induction is ideal for dissecting key phases of the commitment process. We find in Xenopus tropicalis, at the time of specification of the lens, i.e. when presumptive lens ectoderm (PLE) can be isolated, cultured and will differentiate into a lens, that the PLE is not yet irreversibly committed, or determined, to form a lens. When transplanted into the posterior of a host embryo lens development is prevented at this stage, while approximately 3 hr later, using the same assay, determination is complete. Interestingly, we find that specified lens ectoderm, when cultured, acquires the ability to become determined without further tissue interactions. Further, we show that specified PLE has a different gene expression pattern than determined PLE, and that determined PLE can maintain expression of essential regulatory genes (e.g. foxe3, mafB) in an ectopic environment while specified PLE cannot. These observations set the stage for a detailed mechanistic study of the genes and signals controlling tissue commitment. PMID:22566346

Fluctuations of the experience of togetherness within the team over time: task-cohesion and shared understanding throughout a sporting regular season.

Bourbousson, Jérôme; Fortes-Bourbousson, Marina

2017-06-01

Based on a diagnosis action research design, the present study assessed the fluctuations of the team experience of togetherness. Reported experiences of 12 basketball team members playing in the under-18 years old national championship were studied during a four-month training and competitive period. Time series analysis (Auto-Regressive Integrated Moving Average procedures) served to describe temporal properties of the way in which the fluctuations of task-cohesion and shared understanding were step-by-step experienced over time, respectively. Correlations, running-correlations and cross-lagged correlations were used to describe the temporal links that governed the relationships between both phenomena. The results indicated that the task-cohesion dimensions differed mainly for shared understanding dynamics in that their time fluctuations were not embedded in external events, and that the variations in shared understanding tend to precede 'individual attractions to the task' variations with seven team practical sessions. This study argues for further investigation of how 'togetherness' is experienced alternatively as a feeling of cohesion or shared understanding. Practitioner Summary: The present action research study investigated the experience that the team members have to share information during practice, and the subsequent benefices on team cohesion. Results call for specific interventions that make team members accept the fluctuating nature of team phenomena, to help them maintaining their daily efforts.

Noelia Belando Pedreño

2016-03-01

Full Text Available The aim of this study was to contribute to the postulates of the self-determination theory, the hierarchical model of intrinsic and extrinsic motivation by Vallerand, and social goals. A structural regression model was estimated to analyze the relations between social goals (responsibility and relationships, praise for autonomous behavior, satisfaction of the basic psychological needs and intrinsic motivation in commitment to sport. A sample of 264 young Spanish soccer players aged between 14 and 16 (M =14.74, SD =.77 participated in the study. Structural Equation Modeling results showed that the social responsibility goal, the social relationship goal and praise for autonomous behavior predicted perceived competence. Furthermore, the relationship goal also predicted the need for relatedness. Satisfaction of the basic psychological needs for competence and relatedness predicted intrinsic motivation. Intrinsic motivation positively predicted future commitment to sport. These results highlighted the importance of social goals, praise for autonomous behavior and psychological mediators in encouraging greater commitment in young soccer players. Future research should focus on the coach’s role in generating greater commitment to sport through the development of intervention methodologies based on social goals.

Commitment to Cooperation and Peer Punishment: Its Evolution

Directory of Open Access Journals (Sweden)

Tatsuya Sasaki

2015-11-01

Full Text Available Theoretical and empirical studies have generally weighed the effect of peer punishment and pool punishment for sanctioning free riders separately. However, these sanctioning mechanisms often pose a puzzling tradeoff between efficiency and stability in detecting and punishing free riders. Here, we combine the key aspects of these qualitatively different mechanisms in terms of evolutionary game theory. Based on the dilemmatic donation game, we introduce a strategy of commitment to both cooperation and peer punishment. To make the commitment credible, we assume that those willing to commit have to make a certain deposit. The deposit will be refunded as long as the committers faithfully cooperate in the donation game and punish free riders and non-committers. It turns out that the deposit-based commitment offers both the efficiency of peer punishment and the stability of pool punishment and that the replicator dynamics lead to transitions of different systems: pool punishment to commitment to peer punishment.

The high turnover of nurses has become a universal issue. The manner in which nurses view their organization's ethical climate has direct bearing on their organizational commitment. The aim of this study was to determine the correlation between nurses' perception of ethical climate and organizational commitment in teaching hospitals in the southeastern region of Iran. A descriptive analytical design was used in this study. The sample consisted of 275 nurses working in four teaching hospitals in the southeastern region of Iran. The instruments used in this study included a demographic questionnaire, Ethical Climate Questionnaire, and Organizational Commitment Questionnaire. Data analysis was carried out using Pearson's correlation, t-test, and descriptive statistic through Statistical Package for Social Science, version 16. The result of this research indicated a positive correlation among professionalism, caring, rules, independence climate, and organizational commitment. Therefore, findings of this study are a guideline for researchers and managers alike who endeavor to improve organizational commitment.

These lead to different ways of entering into the commitment, with differing consequences on how the individual functions. Copyright © 2017 Elsevier Masson SAS. All rights reserved.

Predicting multiprocessing efficiency on the Cray multiprocessors in a (CTSS) time-sharing environment/application to a 3-D magnetohydrodynamics code

International Nuclear Information System (INIS)

Mirin, A.A.

1988-01-01

A formula is derived for predicting multiprocessing efficiency on Cray supercomputers equipped with the Cray Time-Sharing System (CTSS). The model is applicable to an intensive time-sharing environment. The actual efficiency estimate depends on three factors: the code size, task length, and job mix. The implementation of multitasking in a three-dimensional plasma magnetohydrodynamics (MHD) code, TEMCO, is discussed. TEMCO solves the primitive one-fluid compressible MHD equations and includes resistive and Hall effects in Ohm's law. Virtually all segments of the main time-integration loop are multitasked. The multiprocessing efficiency model is applied to TEMCO. Excellent agreement is obtained between the actual multiprocessing efficiency and the theoretical prediction

Hidden power system inflexibilities imposed by traditional unit commitment formulations

Highlights: • Quality and accuracy of traditional-energy- and power-based UCs are evaluated. • Real-time performance evaluation simulating “perfect” stochastic UCs. • Ideal energy-based stochastic UC formulations impose hidden system inflexibilities. • A deterministic power-based UC may outperform an ideal energy-based stochastic UC. • Power-based UC overcomes flaws of energy-based UC: lower cost and wind curtailment. - Abstract: Approximations made in traditional day-ahead unit commitment model formulations can result in suboptimal or even infeasible schedules for slow-start units and inaccurate predictions of actual costs and wind curtailment. With increasing wind penetration, these errors will become economically more significant. Here, we consider inaccuracies from three approximations: the use of hourly intervals in which energy production from each generator is modeled as being constant; the disregarding of startup and shutdown energy trajectories; and optimization based on expected wind profiles. The results of unit commitment formulations with those assumptions are compared to models that: (1) use a piecewise-linear power profiles of generation, load and wind, instead of the traditional stepwise energy profiles; (2) consider startup/shutdown trajectories; and (3) include many possible wind trajectories in a stochastic framework. The day-ahead hourly schedules of slow-start generators are then evaluated against actual wind and load profiles using a model real-time dispatch and quick-start unit commitment with a 5 min time step. We find that each simplification usually causes expected generation costs to increase by several percentage points, and results in significant understatement of expected wind curtailment and, in some cases, load interruptions. The inclusion of startup and shutdown trajectories often yielded the largest improvements in schedule performance.

Every year, research specimens are shipped from one institution to another as well as across national boundaries. A significant proportion of specimens move from poor to rich countries. Concerns are always raised on the future usage of the stored specimens shipped to research institutions from developing countries. Creating awareness of the processes is required in all sectors involved in biomedical research. To maintain fairness and respect in sharing biomedical specimens and research products requires safeguarding by Ethics Review Committees in both provider and recipient institutions. Training in basic ethical principles in research is required to all sectors involved in biomedical research so as to level up the research playing field. By agreeing to provide specimens, individuals and communities from whom samples are collected would have placed their trust and all ensuing up-keep of the specimens to the researchers. In most collaborative set-up, laid down material transfer agreements are negotiated and signed before the shipment of specimens. Researchers, research ethics committees (RECs) and institutions in the countries of origin are supposed to serve as overseers of the specimens. There is need to advocate for honesty in sample handling and sharing, and also need to oversee any written commitments by researchers, RECs and institutions at source as well as in recipient institution. Commitments from source RECs and Institutional Review Boards (IRBs) and in the receiving institution on overseeing the future usage of stored specimens are required; including the ultimate confirmation abiding by the agreement. Training in ethical issues pertaining to sample handling and biomedical research in general is essential at all levels of academic pursuit. While sharing of biological specimens and research data demands honesty and oversight by ethical regulatory agents from both institutions in developing country and recipient institutions in developed countries.

Soors, Werner; De Paepe, Pierre; Unger, Jean-Pierre

2014-01-01

Maintained dedication to primary care has fostered a public health delivery system with exceptional outcomes in Costa Rica. For more than a decade, management commitments have been part of Costa Rican health reform. We assessed the effect of the Costa Rican management commitments on access and quality of care and on compliance with their intended objectives. We constructed seven hypotheses on opinions of primary care providers. Through a mixed qualitative and quantitative approach, we tested these hypotheses and interpreted the research findings. Management commitments consume an excessive proportion of consultation time, inflate recordkeeping, reduce comprehensiveness in primary care consultations, and induce a disproportionate consumption of hospital emergency services. Their formulation relies on norms in need of optimization, their control on unreliable sources. They also affect professionalism. In Costa Rica, management commitments negatively affect access and quality of care and pose a threat to the public service delivery system. The failures of this pay-for-performance-like initiative in an otherwise well-performing health system cast doubts on the appropriateness of pay-for-performance for health systems strengthening in less advanced environments.

Global collective dose commitments from release of long-lived radionuclides. Differential cost-benefit considerations

International Nuclear Information System (INIS)

Gjoerup, H.L.

1977-01-01

The concept of global collective dose commitment as a measure of total detriment from the release of radioactivity to the environment is outlined. Estimates are given of global collective dose commitments resulting from the release of 14 C and uranium daughter products from the nuclear fuel cycle. Comparisons are made with similar estimates of global collective dose commitments resulting from the use of fossil fuels and certain fertilizers due to their content of uranium and its daughter products. In the case of long-lived radionuclides that remain in circulation in the biosphere, it is shown that the use of global collective dose commitments in differential cost-benefit analysis can lead to questionable results. In differential cost-benefit analysis it is suggested that population exposures should not simply be integrated irrespective of their time of occurrence, but that a certain discount rate should be applied for future doses. This suggestion is examined. (author)

Cases in which people use fire when attempting or committing suicide are not common but nevertheless constitute a cause of admission to burns units worldwide. Usually these people are suffering from stress and have been diagnosed as mentally ill. Schizophrenia, depression, and personality disorders are the most frequently diagnosed conditions. The psychological problems appear to have been overlooked by the family or not to have been presented to them. The aim of this study is to present the clinical features, characteristics, and outcomes of patients burned during a suicide attempt. The role of the psychiatrist is important, starting in the emergency room. The incidence of patients committing self-injury by burning appears to be higher in women burn patients. Deceased patients usually have a larger extent of burns and a higher incidence of other injuries and require more surgical procedures and longer hospitalization times. The problems for burn unit staff and qualified psychiatric care are discussed.

2017-05-01

Full Text Available Background This article is focused on the entitlement attitude in an organizational context. Its purpose was to examine the relationship of entitlement and its 3 components (active, passive and revengefulness with job satisfaction and organizational commitment. Participants and procedure Two independent studies were conducted to examine the discussed relationships. In study 1 and study 2 there participated respectively 110 and 95 full-time employees from both genders working in public and private organizations. The 30-item Bulgarian version of the Entitlement Questionnaire was used. Job satisfaction measurement included employees’ affective response to their overall job and to various aspects of their job. The three aspects of organizational commitment (affective, instrumental and normative were measured. Results Active entitlement had a positive effect on satisfaction with results, satisfaction with supervisor, pay satisfaction and overall job satisfaction. It was not related to organizational commitment. Passive entitlement had a positive effect on satisfaction with tasks, but it correlated negatively with pay satisfaction. Higher level of passive entitlement predicted instrumental commitment. Revengefulness was negatively related to task satisfaction, satisfaction with supervisor and overall satisfaction, and had a negative effect on affective commitment. Conclusions Different forms of entitlement have a diverse influence on the various aspects of job satisfaction and components of organizational commitment. Active and passive types of entitlement are more adaptive, whereas revengefulness is a maladaptive and dysfunctional attitude.

Device-independent bit commitment based on the CHSH inequality

International Nuclear Information System (INIS)

Aharon, N; Massar, S; Pironio, S; Silman, J

2016-01-01

Bit commitment and coin flipping occupy a unique place in the device-independent landscape, as the only device-independent protocols thus far suggested for these tasks are reliant on tripartite GHZ correlations. Indeed, we know of no other bipartite tasks, which admit a device-independent formulation, but which are not known to be implementable using only bipartite nonlocality. Another interesting feature of these protocols is that the pseudo-telepathic nature of GHZ correlations—in contrast to the generally statistical character of nonlocal correlations, such as those arising in the violation of the CHSH inequality—is essential to their formulation and analysis. In this work, we present a device-independent bit commitment protocol based on CHSH testing, which achieves the same security as the optimal GHZ-based protocol, albeit at the price of fixing the time at which Alice reveals her commitment. The protocol is analyzed in the most general settings, where the devices are used repeatedly and may have long-term quantum memory. We also recast the protocol in a post-quantum setting where both honest and dishonest parties are restricted only by the impossibility of signaling, and find that overall the supra-quantum structure allows for greater security.

2016-03-01

Full Text Available In this quantitative research, we enhance understanding of psychological safety on employee voice behavior by examining mediating role of affective commitment and intrinsic motivation. We examined these relationships among 151 research assistants working full-time for universities. The results suggest that psychological safety is significantly associated with affective commitment whereas it does not significantly influence intrinsic motivation. Furthermore, employee voice behavior is affected by intrinsic motivation but not by affective commitment. Lastly, while affective commitment plays an important role as mediator in the relationship between psychological safety and employee voice although intrinsic motivation does not have a mediating effect. We discuss the implications of these findings for both theory and practice.

It was possible to rescue the responsibility concepts, social commitment and identify the elderly in the university, within the federal legislation, through bibliographical and documentary research. There was a survey of permanent education programs with at least 20 years, in 2016. It was carried out for the elderly in the 63 Brazilian Federal, and Public Universities and 17 cases were found. Thus, nine Pro-Rectors of Extension and a Unit Director accepted to participate in interviews by Skype or telephone, in the second semester of 2016, fulfilling the objective of describing the university authorities’ vision on the type of institutional support for such programs’ operation. Although it is possible to realize their relevance to the environment and the university, the institutional commitment is still far short of what is necessary.

Karsh, Ben-Tzion; Beasley, John W; Brown, Roger L

2010-04-01

Test a model of family physician job satisfaction and commitment. Data were collected from 1,482 family physicians in a Midwest state during 2000-2001. The sampling frame came from the membership listing of the state's family physician association, and the analyzed dataset included family physicians employed by large multispecialty group practices. A cross-sectional survey was used to collect data about physician working conditions, job satisfaction, commitment, and demographic variables. The response rate was 47 percent. Different variables predicted the different measures of satisfaction and commitment. Satisfaction with one's health care organization (HCO) was most strongly predicted by the degree to which physicians perceived that management valued and recognized them and by the extent to which physicians perceived the organization's goals to be compatible with their own. Satisfaction with one's workgroup was most strongly predicted by the social relationship with members of the workgroup; satisfaction with one's practice was most strongly predicted by relationships with patients. Commitment to one's workgroup was predicted by relationships with one's workgroup. Commitment to one's HCO was predicted by relationships with management of the HCO. Social relationships are stronger predictors of employed family physician satisfaction and commitment than staff support, job control, income, or time pressure.

Considerations in civil commitment of individuals with substance use disorders.

Science.gov (United States)

Cavaiola, Alan A; Dolan, David

2016-01-01

Several states currently have enacted laws that allow for civil commitment for individuals diagnosed with severe substance use disorders. Civil commitment or involuntary commitment refers to the legal process by which individuals with mental illness are court-ordered into inpatient and/or outpatient treatment programs. Although initially civil commitment laws were intended for individuals with severe mental illness, these statutes have been extended to cover individuals with severe substance use disorders. Much of the recent legislation allowing for civil commitment of individuals with substance use disorders has come about in response to the heroin epidemic and is designed to provide an alternative to the unrelenting progression of opioid use disorders. Civil commitment also provides an opportunity for individuals with opioid use disorders to make informed decisions regarding ongoing or continued treatment. However, civil commitment also raises concerns regarding the potential violation of 14th Amendment rights, specifically pertaining to abuses of deprivation of liberty or freedom, which are guaranteed under the 14th Amendment to the United States Constitution. This commentary examines these issues while supporting the need for effective brief civil commitment legislation in all states.

Motivated reconstruction: The effect of brand commitment on false memories.

Science.gov (United States)

Montgomery, Nicole Votolato; Rajagopal, Priyali

2018-06-01

Across 5 studies, we examine the effect of prior brand commitment on the creation of false memories about product experience after reading online product reviews. We find that brand commitment and the valence of reviews to which consumers are exposed, interact to affect the incidence of false memories. Thus, highly committed consumers are more susceptible to the creation of false experience memories on exposure to positive versus negative reviews, whereas low commitment consumers exhibit similar levels of false memories in response to both positive and negative reviews. Further, these differences across brand commitment are attenuated when respondents are primed with an accuracy motivation, suggesting that the biasing effects of commitment are likely because of the motivation to defend the committed brand. Finally, we find that differences in false memories subsequently lead to differences in intentions to spread word-of-mouth (e.g., recommend the product to friends), suggesting that the consequences of false product experience memories can be significant for marketers and consumers. Our findings contribute to the literatures in false memory and marketing by documenting a motivated bias in false memories because of brand commitment.

When will we be committed to crossing 1.5 and 2 °C temperature thresholds?

Science.gov (United States)

Armour, K.; Proistosescu, C.; Roe, G.; Huybers, P. J.

2017-12-01

The zero-emissions climate commitment is a key metric for science and policy. It is the future warming we face given only to-date emissions, independent of future human influence on climate. Following a cessation of emissions, future global temperature change depends on (i) the atmospheric lifetimes of aerosols and greenhouse gases (GHGs), and (ii) the physical climate response to radiative forcing (Armour and Roe 2011). The cooling effect of aerosols diminishes within weeks; GHG concentrations get drawn down on timescales ranging from months to millennia; and ocean heat uptake diminishes as climate equilibrates with the residual CO2 forcing. Whether global temperature increases, stays stable, or declines following emission cessation depends on these competing factors. There is substantial uncertainty in the zero-emissions commitment due to a combination of (i) correlated uncertainties in aerosol radiative forcing and climate sensitivity, (ii) uncertainty in the atmospheric lifetime of CO2, and (iii) uncertainty in how climate sensitivity will evolve in the future. Here we quantify climate commitment in a Bayesian framework of an idealized model constrained by observations of global warming and energy imbalance, combined with estimates of global radiative forcing. At present, our committed warming is 1.2°C (median), with a 25% chance that it already exceeds 1.5°C and a 5% chance that it exceeds 2°C; the range comes primarily from uncertainty in the degree to which aerosols currently mask GHG forcing. We further quantify how climate commitment, and its uncertainty, changes with emissions scenario and over time. Under high emissions (RCP8.5), we will reach a >50% risk of a 2°C zero-emission climate commitment by the year 2035, about two decades before that temperature would be reached if emissions continued unabated. Committed warming is substantially reduced for lower-emissions scenarios, depending on the mix of aerosol and GHG mitigation. For the next few

On Converting Secret Sharing Scheme to Visual Secret Sharing Scheme

Directory of Open Access Journals (Sweden)

Wang Daoshun

2010-01-01

Full Text Available Abstract Traditional Secret Sharing (SS schemes reconstruct secret exactly the same as the original one but involve complex computation. Visual Secret Sharing (VSS schemes decode the secret without computation, but each share is m times as big as the original and the quality of the reconstructed secret image is reduced. Probabilistic visual secret sharing (Prob.VSS schemes for a binary image use only one subpixel to share the secret image; however the probability of white pixels in a white area is higher than that in a black area in the reconstructed secret image. SS schemes, VSS schemes, and Prob. VSS schemes have various construction methods and advantages. This paper first presents an approach to convert (transform a -SS scheme to a -VSS scheme for greyscale images. The generation of the shadow images (shares is based on Boolean XOR operation. The secret image can be reconstructed directly by performing Boolean OR operation, as in most conventional VSS schemes. Its pixel expansion is significantly smaller than that of VSS schemes. The quality of the reconstructed images, measured by average contrast, is the same as VSS schemes. Then a novel matrix-concatenation approach is used to extend the greyscale -SS scheme to a more general case of greyscale -VSS scheme.

2015-04-01

This paper proposes a cheat-sensitive quantum bit commitment scheme based on single photons, in which Alice commits a bit to Bob. Here, Bob’s probability of success at cheating as obtains the committed bit before the opening phase becomes close to \\frac{1}{2} (just like performing a guess) as the number of single photons used is increased. And if Alice alters her committed bit after the commitment phase, her cheating will be detected with a probability that becomes close to 1 as the number of single photons used is increased. The scheme is easy to realize with present day technology.

2014-02-01

Full Text Available This paper presents an empirical investigation to study the relationship between social capital and organizational commitment. The study considers the relationship between social capital with three components of organizational commitment; namely, affective commitment, continuous and normative commitment. The study has been applied among a sample of 292 regular employees who worked for an Iranian bank located in city of Tehran, Iran. The implementation of Pearson correlation has indicated that there were positive and meaningful relationships between social capital and affective commitment (r = 0.197, Sig. = 0.01, continuous (r = 0.308, Sig. = 0.01 and normative commitment (r = 0.423, Sig. = 0.01. In addition, the study has detected that women had more commitment on their organization than men did. The proposed study of this paper has also considered a regression model where organizational commitment is dependent variable and trust and communication are considered as independent variables. According to the results of regression analysis, an increase of one unit in trust and social capital communication will increase organizational commitment by 0.189 and 0.204, respectively.

Attachment to God, religious tradition, and firm attributes in workplace commitment.

2017-01-01

Research on organizational commitment suggests there is an association between American theists' emotional attachment to God and their emotional commitment to the workplace. A sense of divine calling has been shown to partially mediate this association but, beyond that, little is known. The purpose of this study is to shed further light on the relationship between secure attachment to God and affective organizational commitment. I do so by testing whether the employee's religious tradition is associated with affective organizational commitment and whether the employee's firm attributes moderate the relationship between attachment to God and organizational commitment. Results suggest that: 1) Catholics evince higher levels of organizational commitment than Evangelicals, and 2) firm size significantly moderates the relationship between attachment to God and organizational commitment across religious affiliations.

When Sharing Is a Bad Idea: The Effects of Online Social Network Engagement and Sharing Passwords with Friends on Cyberbullying Involvement.

Science.gov (United States)

Meter, Diana J; Bauman, Sheri

2015-08-01

Every day, children and adolescents communicate online via social networking sites (SNSs). They also report sharing passwords with peers and friends, a potentially risky behavior in regard to cyber safety. This longitudinal study tested the hypotheses that social network engagement in multiple settings would predict more cyberbullying involvement over time, and that youth who reported sharing passwords would also experience an increase in cyberbullying involvement. Data were collected at two time points one year apart from 1,272 third through eighth grade students. In line with the first study hypothesis, participating in more online SNSs was associated with increased cyberbullying involvement over time, as well as sharing passwords over time. Cyberbullying involvement at T1 predicted decreases in sharing passwords over time, suggesting that youth become aware of the dangers of sharing passwords as a result of their experience. Sharing passwords at T1 was unrelated to cyberbullying involvement at T2. Although it seems that youth may be learning from their previous mistakes, due to the widespread use of social media and normality of sharing passwords among young people, it is important to continue to educate youth about cyber safety and risky online behavior.

Journey to a shared vision for nursing in a university hospital

Directory of Open Access Journals (Sweden)

Jacqueline S. Martin

2016-11-01

Full Text Available Background: Demographic and epidemiological shifts, as well as increasing quality control and greater emphasis on cost effectiveness are the challenges for today’s healthcare organisations. Against this background, institutions are undertaking reforming processes in order to adapt to this complex and unstable market. These transformations require innovative practice and highly effective leadership – leaders who are capable of conveying the need for change and creating a vision for the future. Despite its growing importance, the development process of such a vision is barely addressed in the literature. Aim: The aim of this article is to describe the process of a university hospital towards developing a shared vision for nursing practice. Methods: By means of the four phases of the evidence-based appreciative inquiry process (Discovery – Dream – Design – Destiny, a shared vision was developed. The main methods used were individual interviews, focus group interviews and SWOT analyses. The different datasets produced were synthesised and abstracted to form a vision and corresponding strategic objectives. Conclusions: Although the developmental process was rather time consuming and complex, it provided a systematic approach to change and enabled the leaders involved to commit to the strategic orientation. Implications for practice: A vision provides direction and meaning for leaders and their teams in complex transformation processes within healthcare organisations The approach of appreciative inquiry is well suited to facilitate the creative and innovative process of developing a vision Before initiating the process of developing a vision, it is important to consider the time factor and to plan accordingly so that the necessary creative thinking and reflection can take place

Full Text Available The entry of small businesses into international markets has intensified. However, despite the growing presence of small businesses in international markets, studies into their international behavior, particularly regarding the effect of international relationships on international outcomes, remain limited. This study investigates the cross-border relationships of Small and Medium Enterprises (SMEs by examining the effects of the dimensions of the key relationship on the competitive advantage and performance of SMEs in export markets. These dimensions include trust and commitment. Results indicate that trust is significantly related to commitment and export performance. Commitment is positively related to competitive advantage but not to export performance. Trust affects competitive advantage through commitment. The effect of commitment on export performance is mediated by competitive advantage. The methodology and results are presented. The conclusion, implications, and limitations of this study are also discussed.

Nursing care encompasses physical, emotional, mental and social needs, in order to improve a patient's health and wellbeing. Caring is the central core and the essence of nursing. The important issue of care is access to proper care and increasing patients' satisfaction. Job performance of nurses is affected by many factors including organizational commitment. This study aimed to determine the relationship between organizational commitment and nurses caring behavior. In this cross-sectional study, 322 nurses from selected Hospitals of Shahid Beheshti University of Medical Sciences in Tehran were randomly selected and enrolled in the study in 2015. The self-reported data by nurses were collected through demographic characteristics questionnaire, Meyer & Allen organizational commitment model and Caring Behavior Inventory (CBI). Data were analyzed with SPSS statistical software version 20, using t-test and ANOVA. The majority of nurses (63%) were female. The mean score and standard deviation of organizational commitment and caring behavior of nurses were 74.12±9.61 and 203.1±22.46, respectively. The results showed a significantly positive correlation between organizational commitment and caring behavior (p=0.001). In this study the caring behavior of nurses with higher organizational commitment were significantly better than the others. Managers and nurse leaders should pay more attention to improve organizational commitment of nurses, in order to improve nurses' performance.

While the impact of burnout on organisational commitment has been widely observed, its impact on nursing professional commitment has not previously been investigated. The literature has clarified that professional commitment has three distinct components: affective, continuance and normative. This study aims to investigate the relationships between burnout and the three components of nursing professional commitment. This was a cross-sectional study using questionnaires to collect data in one large medical centre. Responses from 571 nurses were used for regression analysis. Among the sampled nurses, 90.9% had professional commitment came from Meyer et al. (J Appl Psychol, 78, 1993 and 538) a formally validated instrument. Analytical results indicated that burnout is negatively related to affective and normative professional commitment (B ≤ -0.09, p professional commitment (B = 0.05, p > 0.05). Nurse managers aiming to improve nurses' professional commitment should consider reducing nurses' burnout, for example improving nursing optimism and reducing administrative tasks, as suggested by the literature. © 2017 Nordic College of Caring Science.

Mentally ill persons who commit crimes: punishment or treatment?

Science.gov (United States)

Melamed, Yuval

2010-01-01

In many countries, there continue to be conflicting opinions and mechanisms regarding the appropriateness of treatment and/or punishment for mentally ill individuals who commit crimes. The general population is concerned with public safety and often finds it difficult to accept the possibility that a mentally ill individual who commits a crime can be hospitalized and eventually discharged, sometimes after a relatively short time. In most countries the options of incarceration and hospitalization are available in concert. In some, incarceration occurs before hospitalization. In others, hospitalization is first, followed by a prison term. An additional option could be "treatment years." The court would determine the number of years of treatment required, according to the crime. This dilemma has no unequivocal solution. The goal is to reach a balance between the right of the patient to treatment and the responsibility of the courts to ensure public safety.

To measure the relationship between job satisfaction and the 3 components of organizational commitment. Most of the research conducted in the West has shown a positive relationship between organizational commitment and job satisfaction of nurses; however, the relationship between the components of organizational commitment and job satisfaction is not well established in Iranian samples. This study aimed to investigate the level of organizational commitment and job satisfaction of the hospital nurses in Iran and the interrelationship between the 3 components of commitment and job satisfaction among them. Using the organizational commitment questionnaire developed by Meyer et al (J Appl Psychol. 1993;78:538-551), the 3 components of commitment were measured through a descriptive correlational design. Seven hundred eighty-six licensed nurses working in 12 hospitals participated in the study. One hundred ninety-eight of 220 returned questionnaires were identified as appropriate for the analysis. Affective commitment was positively related to job satisfaction, normative commitment, and experience in nursing, but it was negatively related to continuance commitment. Continuance commitment was negatively related to job satisfaction and affective commitment. Normative commitment was positively related to job satisfaction and affective commitment. The 3 components of commitment are variously related to job satisfaction. Nursing managers should pay attention to different components of commitment variously to promote the appropriate type of commitment needed for specific situation in which they work.

Population dose commitments due to radioactive releases from nuclear power plant sites in 1988

Baker, D.A.

1992-01-01

Population radiation dose commitments have been estimated from reported radionuclide releases from commercial power reactors operating during 1988. Fifty-year commitments for a one-year exposure from both liquid and atmospheric releases were calculated for four population groups (infant, child, teen-ager and adult) residing between 2 and 80 km from each of 71 reactor sites. This report tabulates the results of these calculations, showing the dose commitments for both water and airborne pathways for each age group and organ. Also included for each of the sites is a histogram showing the fraction of the total population within 2 to 80 km around each site receiving various average dose commitments from the airborne pathways. The total collective dose commitments (from both liquid and airborne pathways) for each site ranged from a high of 16 person-rem to a low of 0.0011 person-rem for the sites with plants operating throughout the year with an arithmetic mean of 1.1 person-rem. The total population dose for all sites was estimated at 75 person-rem for the 150 million people considered at risk. The site average individual dose commitment from all pathways ranged from a low of 3 x 10 -7 mrem to a high of 0.02 mrem. No attempt was made in this study to determine the maximum dose commitment received by any one individual from the radionuclides released at any of the sites. However, licensee calculation of doses to the maximally exposed individual at some sites indicated values of up to approximately 100 times average individual doses (on the order of a few millirem per year)

2014-05-01

Full Text Available It has been argued that individuals’ employment commitment, that is, their commitment to work in general is crucial in today’s labor markets where life-long employment relationships are less frequently offered by organizations. In addition, employees’ organizational commitment, that is, their commitment to their own organization is also vital for organizations and firms, affecting many areas of importance to them. This article asks how Finnish employees rank in both employment commitment and affective organizational commitment compared with employees in 15 other European countries. The data were collected in 2005–2007 through the International Social Survey Program (ISSP, Work Orientation Module III. The results show Finnish employees scoring below European averages in both types of commitment when employee-level and organizationlevel factors are taken into account. Employment commitment was highest in Norway and affective organizational commitment highest in Portugal. The perceived intrinsic rewards of the job were the strongest predictor of employment and affective organizational commitment in most of the countries researched, increasing both these types of commitment. However, the perceived social relations between management and employees were found to be the most powerful determinant of affective organizational commitment in Finland, with perceived good relations adding to the affective organizational commitment of employees. The data were analyzed mainly by means of a general linear model procedure.

Commentary: civil commitment statutes--40 years of circumvention.

Fisher, William H; Grisso, Thomas

2010-01-01

There is a longstanding body of literature that describes how states' civil commitment statutes have been stretched or circumvented to accommodate institutional and systemic needs. The paper by Levitt and colleagues provides yet another example of this phenomenon: Arizona's use of its civil commitment statutes to detain unrestorable, incompetent criminal defendants for whom other provisions have not been developed. This commentary provides a brief overview of other examples of the stretching of commitment laws, providing a broader context for viewing the findings of Levitt and colleagues.

Shared Contract-Obedient Endpoints

Directory of Open Access Journals (Sweden)

Étienne Lozes

2012-12-01

Full Text Available Most of the existing verification techniques for message-passing programs suppose either that channel endpoints are used in a linear fashion, where at most one thread may send or receive from an endpoint at any given time, or that endpoints may be used arbitrarily by any number of threads. The former approach usually forbids the sharing of channels while the latter limits what is provable about programs. In this paper we propose a midpoint between these techniques by extending a proof system based on separation logic to allow sharing of endpoints. We identify two independent mechanisms for supporting sharing: an extension of fractional shares to endpoints, and a new technique based on what we call reflexive ownership transfer. We demonstrate on a number of examples that a linear treatment of sharing is possible.

Benefits from increased cooperation and energy trade under CO2 commitments - The Nordic case

International Nuclear Information System (INIS)

Unger, Thomas; Ekvall, Tomas

2001-01-01

In this paper, benefits from increasing cross-border cooperation under future CO 2 commitments in the Nordic countries are examined and evaluated. Cooperative strategies including border-free electricity trade, emission-permits trade and extending the natural gas transmission capacity considerably are valued separately and together under varying CO 2 commitments and three different scenarios for future energy demand. In conducting this analysis, the energy-systems engineering model MARKAL was used to model the Nordic energy system. It is shown that all cooperative strategies do lower the abatement costs considerably, especially if all three strategies mentioned are used simultaneously. Additional costs from meeting CO 2 commitments may be at least halved provided that all cooperative strategies are utilized at the same time. Benefits from cooperation are generally larger for scenarios including relatively high future energy demand, while they are lower for scenarios with relatively lower energy demand. In the model used, no specific trend connecting the size of the benefits from cooperation to the size of the CO 2 commitments could be observed

Full Text Available ABSTRACT OBJECTIVE: This study aimed at investigating whether there is a correlation between organizational commitment and narcissistic personalty traits. METHOD: In order to measure the GATA Occupation High School of Health Subordinate Officiers’ narcissistic personality traits Narcissistic Personality Inventory (NPI scala was used. In order to measure students’ organizational commitment Organizational Commitment Questionnaire was used. 229 questionnaire forms were distributed to the Occupation High School of Health Subordinate Officiers’ students, and 220 (%96 of them were returned. Totally 220 students were evaluated. FINDINGS: When students’ narcissistic scores were evaluated out of 16, it was found out that the highest narcissistic personality score (8,98 was taken by second year students, the highest score for organizational commitment (3,70 was taken by first year students, “exploitativeness” which is one of the sub-levels of narcissisim was observed at the highest level with an average of 0,73 out 1 full score, “entitlement” sub level was observed at the lowest level (0,29, “affective commitment” one of the sub-levels of commitment, had the highest average (3,84, “normative commitment” had the second highest average (3,71 and finally “continuance commitment” was observed at the lowest level (3,55. Statistically, there is no significant relationship found between narcissistic personality and organizational commitment. However, there is a significant relationship found between narcissistic personality and continuity commitment. There is a significant and opposite relationship found between organizational commitment and continuity commitment with superiority. There is similar relationship found between exploitation and continuity commitment. CONCLUSION: With respect to these findings, it is suggested that “Health Technicians” candidates’, who will be one of the indispensable constituents of health services

Full Text Available Presently, knowledge is considered as the most strategic resource of organizations. The literature on the subject often raises the issues of commitment. The purpose of the article was to discuss the associations between knowledge management and employee commitment. The article presents the stages of knowledge management and describes the category of commitment, taking account of several criteria. In the opinion of the authors, from the point of view of knowledge management particular importance can be attained to the way qualifications, skills, predispositions and knowledge of employees will be used, which, in turn, depends on "quality" of their commitment (its type, intensity, dimension and direction in achieving organizational goals.

The configural approach to organisational commitment: An application in Ghana

Edward O. Akoto

2014-12-01

Research purpose: To test the theory on profiles of commitment in an African context (Ghana. Motivation for the study: Although the three-component model of organisational commitment has been extended to several regions of Africa, there is a paucity of research on profiles of commitment on the continent. Research approach, design and method: Cross-sectional data from two studies, with samples of 187 and 218, were analysed using k-means clusters. Multivariate analysis of variance (MANOVA was then used to test the differences amongst profiles in their association with contextual variables, such as pay satisfaction, job security, strike propensity and two demographic factors. Main findings: In the k-means cluster analysis, a six-cluster solution emerged in both studies;the profiles include the highly committed and the uncommitted groups, as well as the profiles based on normative commitment and continuance commitment. Overall, the MANOVA post hoc outcome shows that the highly committed group reports higher mean scores on the positive outcome variables (e.g. job security than the uncommitted group. Conversely, the uncommitted group scored relatively higher on the negative organisational outcome (propensity to strike. Other mean differences were found in the respective studies on pay satisfaction, collectivism and the demographic factors. Practical/managerial implications: Employing the configural approach to the study of commitment in this region should increase our understanding of the patterns of attachment and their influence on behaviour. Different patterns of attachment exist within the organisation that may be beneficial or detrimental to behaviour on the job. It is, therefore, important for managers to identify these patterns and target organisational policy and resources appropriately. Contribution/value-add: This study applies the concept of commitment profiles to an untested region: an African context. It, therefore, adds to the literature on the

This study was designed to identify the level of nurses' job satisfaction, occupational commitment and intent to stay among mainland Chinese nurses, to explore the relationship among them.   Little is known about the magnitude of Chinese nurses' intent to stay. Understanding the association among demographic characteristics and job satisfaction, occupational commitment and intent to stay among Chinese nurses is most important in a time of nurse shortages. Methods.  A descriptive correlation design was used to examine the relationship among variables related to intent to stay. Data were collected by a self-administered survey questionnaire from 560 nurses working in four large hospital facilities in Shanghai in 2009. The mean scores for nurses' job satisfaction, occupational commitment and intent to stay were 3·25(0·48), 3·11(0·40) and 3·56(0·65), respectively. Job satisfaction and occupational commitment were significantly related to intent to stay. A statistically significant positive correlation was found between occupational commitment and job satisfaction. Age and job position were significantly related to job satisfaction, occupational commitment and intent to stay. Levels of job satisfaction, occupational commitment and intent to stay reported by nurses in this study can be improved. Suggested strategies for improvement are: increasing salaries, decreasing workloads, modifying task structure, cultivating work passion and creating more professional opportunity for nurses' personal growth development and promotion. Enhancing nurses' job satisfaction and occupational commitment are vital to improve nurses' intent to stay and for strategies to address the nursing shortage. © 2011 Blackwell Publishing Ltd.

Calculation of retention time tolerance windows with absolute confidence from shared liquid chromatographic retention data.

Science.gov (United States)

Boswell, Paul G; Abate-Pella, Daniel; Hewitt, Joshua T

2015-09-18

Compound identification by liquid chromatography-mass spectrometry (LC-MS) is a tedious process, mainly because authentic standards must be run on a user's system to be able to confidently reject a potential identity from its retention time and mass spectral properties. Instead, it would be preferable to use shared retention time/index data to narrow down the identity, but shared data cannot be used to reject candidates with an absolute level of confidence because the data are strongly affected by differences between HPLC systems and experimental conditions. However, a technique called "retention projection" was recently shown to account for many of the differences. In this manuscript, we discuss an approach to calculate appropriate retention time tolerance windows for projected retention times, potentially making it possible to exclude candidates with an absolute level of confidence, without needing to have authentic standards of each candidate on hand. In a range of multi-segment gradients and flow rates run among seven different labs, the new approach calculated tolerance windows that were significantly more appropriate for each retention projection than global tolerance windows calculated for retention projections or linear retention indices. Though there were still some small differences between the labs that evidently were not taken into account, the calculated tolerance windows only needed to be relaxed by 50% to make them appropriate for all labs. Even then, 42% of the tolerance windows calculated in this study without standards were narrower than those required by WADA for positive identification, where standards must be run contemporaneously.

2000-10-01

To assess public attitude, actual working commitment and the respective influence of demographic, psychological and sociological variables on voluntary help in psychiatry. Multiple logistic regression analysis of the results of a representative population survey in Switzerland. Public attitude is mostly positive, but the respective working commitment is small. Attitude depends on gender, psychological factors (social distance, stereotypes), and on attitude to community psychiatry. For the working commitment, clearly distinct predictors are found: age, emotions, participation, and perceived discrimination to the mentally ill. For both attitude and commitment, having a social profession and interest in mass media are predictors. Internationally compared, Switzerland has a positive attitude and a big commitment in lay helping in psychiatry. But attitude is different from actual commitment. Lay helpers' work must be limited to realizable tasks and they need professional recruitment, instruction, and supervision otherwise they tend to be over-burden. The unused potential of voluntary helpers has to be opened specifically, e.g. by involving mass media and opinion-makers.

The aim of this study was to differentiate between homicides committed by multiple offenders and homicides committed by lone offenders. Using data on homicide incidents that occurred in South Korea between 1985 and 2008, we compared 134 homicides committed by multiple offenders, with 369 homicides committed by lone offenders. A greater proportion of homicides committed by multiple offenders involved injuries to the victim's head compared to homicides by lone offenders. Homicides committed by multiple offenders were more likely to involve blunt instruments and ligatures, whereas homicides by lone offenders were more likely to involve sharp instruments. In addition, a majority of the homicides committed by multiple offenders were planned. The results of this study have practical implications for homicide investigations, as well as theoretical implications for homicide research on the difference in offense behaviors based on the number of offenders. © 2018 American Academy of Forensic Sciences.

The aim of this study is to investigate whether organizational justice climate at the workplace level is associated with individual staff members' perceptions of care quality and affective commitment to the workplace. The study adopts a cross-sectional multi-level design. Data were collected using an electronic survey and a response rate of 75% was obtained. Organizational justice climate and affective commitment to the workplace were measured by items from Copenhagen Psychosocial Questionnaire and quality of care by three self-developed items. Non-managerial staff working at dental clinics with at least five respondents (n = 900 from 68 units) was included in analyses. A set of Level-2 random intercept models were built to predict individual-level organizational affective commitment and perceived quality of care from unit-level organizational justice climate, controlling for potential confounding by group size, gender, age, and occupation. The results of the empty model showed substantial between-unit variation for both affective commitment (ICC-1 = 0.17) and quality of care (ICC-1 = 0.12). The overall results showed that the shared perception of organizational justice climate at the clinical unit level was significantly associated with perceived quality of care and affective commitment to the organization (p Organizational justice climate at work unit level explained all variation in affective commitment among dental clinics and was associated with both the individual staff members' affective commitment and perceived quality of care. These findings suggest a potential for that addressing organizational justice climate may be a way to promote quality of care and enhancing affective commitment. However, longitudinal studies are needed to support causality in the examined relationships. Intervention research is also recommended to probe the effectiveness of actions increasing unit-level organizational justice climate and test their impact on quality of care

Challenges and successes in developing a data sharing culture in the Gulf of Mexico following the Deepwater Horizon disaster.

Showalter, L. M.

2017-12-01

The Gulf Research Program (GRP) was developed as part of legal settlements with the companies involved in the Deepwater Horizon (DWH) disaster. The Federal Government asked the National Academy of Sciences to establish a new program to fund and conduct activities to enhance offshore energy system safety and protect human health and the environment in the Gulf of Mexico and other regions along the U.S. outer continental shelf. An important part of the program is a commitment to open data and data sharing among the variety of disciplines it funds. The DWH disaster produced a major influx of funding for the Gulf region and various groups and organizations are collaborating to ensure that the science being conducted via these funding streams is not duplicative. A number of data focused sub groups have formed and are working to leverage existing efforts to strengthen data sharing and collaboration in the region. For its part, the GRP is developing a data program that encourages researchers to share data openly while providing avenues for acknowledgement of data sharing and research collaborations. A main problem with collaborative data sharing is often not the technologies available but instead the human component. The "traditional" path for scientific research has not generally involved making data widely or readily available in a short time frame. It takes a lot of effort to challenge this norm and change the way researchers view data sharing and its value for them and the world at large. The GRP data program aims to build a community of researchers that not only share their data but who also help show the value of this practice to the greater scientific community. To this end, the GRP will support a variety of education and training opportunities to help develop a base of researchers more informed on issues related to open data and data sharing and working to leverage the technology and expertise of others to develop a culture of data sharing in the Gulf of Mexico.

This study investigated how coach and teammates influence masters athletes' sport commitment, and the effect of functional and obligatory commitments on participation in masters swimming. The sample consisted of 523 masters swimmers (330 males and 193 females) aged between 22 and 83 years (M = 39.00, SD = 10.42). A bi-dimensional commitment scale was used to measure commitment dimensions and perceived influence from social agents. Structural equation modelling analysis was conducted to evaluate the influence of social agents on functional and obligatory commitments, and the predictive capabilities of the two types of commitment towards sport participation. Support provided by coach and teammates increased functional commitment, constraints from these social agents determined higher obligatory commitment, and coach constraints negatively impacted functional commitment. In addition, both commitment types predicted training participation, with functional commitment increasing participation in team training sessions, and obligatory commitment increasing the hours of individual training. The findings suggest that in order to increase participation in masters swimming teams and reduce non-supervised training, coach and teammates should exhibit a supportive attitude and avoid over expectation.

Time-dependent fiber bundles with local load sharing. II. General Weibull fibers.

Phoenix, S Leigh; Newman, William I

2009-12-01

Fiber bundle models (FBMs) are useful tools in understanding failure processes in a variety of material systems. While the fibers and load sharing assumptions are easily described, FBM analysis is typically difficult. Monte Carlo methods are also hampered by the severe computational demands of large bundle sizes, which overwhelm just as behavior relevant to real materials starts to emerge. For large size scales, interest continues in idealized FBMs that assume either equal load sharing (ELS) or local load sharing (LLS) among fibers, rules that reflect features of real load redistribution in elastic lattices. The present work focuses on a one-dimensional bundle of N fibers under LLS where life consumption in a fiber follows a power law in its load, with exponent rho , and integrated over time. This life consumption function is further embodied in a functional form resulting in a Weibull distribution for lifetime under constant fiber stress and with Weibull exponent, beta. Thus the failure rate of a fiber depends on its past load history, except for beta=1 . We develop asymptotic results validated by Monte Carlo simulation using a computational algorithm developed in our previous work [Phys. Rev. E 63, 021507 (2001)] that greatly increases the size, N , of treatable bundles (e.g., 10(6) fibers in 10(3) realizations). In particular, our algorithm is O(N ln N) in contrast with former algorithms which were O(N2) making this investigation possible. Regimes are found for (beta,rho) pairs that yield contrasting behavior for large N. For rho>1 and large N, brittle weakest volume behavior emerges in terms of characteristic elements (groupings of fibers) derived from critical cluster formation, and the lifetime eventually goes to zero as N-->infinity , unlike ELS, which yields a finite limiting mean.

To generate an Arabic version of the Organizational Commitment Questionnaire that would be easily understood by Arabic speakers and would be sensitive to Arabic culture. The nursing workforce in Saudi Arabia is undergoing a process of Saudization but there is a need to understand the factors that will help to retain this workforce. No organizational commitment tools exist in Arabic that are specifically designed for health organizations. An Arabic version of the organizational commitment tool could aid Arabic speaking employers to understand their employees' perceptions of their organizations. Translation and back-translation followed by factor analysis (principal components analysis and confirmatory factor analysis) to test the factorial validity and item response theory (Mokken scaling). A two-factor structure was obtained for the Organizational Commitment Questionnaire comprising Factor 1: Value commitment; and Factor 2: Commitment to stay with acceptable reliability measured by internal consistency. A Mokken scale was obtained including items from both factors showing a hierarchy of items running from commitment to the organization and commitment to self. This study shows that the Arabic version of the OCQ retained the established two-factor structure of the original English-language version. Although the two factors - 'value commitment' and 'commitment to stay' - repudiate the original developers' single factor claim. A useful insight into the structure of the Organizational Commitment Questionnaire has been obtained with the novel addition of a hierarchical scale. The Organizational Commitment Questionnaire is now ready to be used with nurses in the Arab speaking world and could be used a tool to measure the contemporary commitment of nursing employees and in future interventions aimed at increasing commitment and retention of valuable nursing staff. © 2018 International Council of Nurses.

Only a few general practitioners (GPs) are committed to screen their patients for alcohol consumption and, in case of excessive alcohol consumption conduct by a brief intervention according to WHO recommendations. Apart from inadequate compensation and work load, another barrier identified by the GPs was their uncertainty about how to deal with affected patients. Most German universities presently spend no more than 90minutes lecture time on addiction medicine teaching. Our research aims to investigate the question whether medical studies and advanced medical education increases the role security of medical students and physicians and their commitment to implementing alcohol screening and brief intervention. Moreover, we will explore whether lack of therapeutic commitment can be related to lack of role security. Questionnaires were administered to pre-clinical and clinical medical students as well as senior house officers. Role security and therapeutic commitment of students and senior house officers were assessed using the Alcohol and Alcohol Problems Questionnaire (SAAPPQ) subscales "Role Security" and "Therapeutic Commitment". Analysis was based on 367 questionnaires. As expected, senior house officers reported more Role Security than clinical medical students who showed a higher level of Role Security than pre-clinical medical students. No differences could be found for Therapeutic Commitment. An association between Role Security and Therapeutic Commitment was only revealed for clinical medical students. Medical studies and advanced medical education can increase students' and senior house officers' Role Security to treat patients with excessive alcohol consumption, but not Therapeutic Commitment. Moreover, no association between Role Security and Therapeutic Commitment could be found for senior house officers. Hence, it may be assumed that educational activities aiming to increase Role Security do not promote the development of motivational aspects such as

This study empirically examined the debate in the literature regarding the dimensionality of the Organizational Commitment Questionnaire. The sample comprised 803 employees from organizations in the information technology and hospitality industries. Confirmatory factor analysis showed that the Organizational Commitment Questionnaire appears to have a two-factor structure, with one factor consisting of positively worded items and the other factor, negatively worded items. Scores on both factors correlated significantly with job satisfaction, suggesting that both factors appear to be measuring a similar aspect of organizational commitment and that they present as two factors given as measurement artifacts of the item wording.

New Graduate Nurses' Professional Commitment: Antecedents and Outcomes.

Guerrero, Sylvie; Chênevert, Denis; Kilroy, Steven

2017-09-01

This study examines the factors that increase new graduate nurses' professional commitment and how this professional commitment in turn affects professional turnover intentions, anxiety, and physical health symptoms. The study was carried out in association with the nursing undergraduate's affiliation of Quebec, Canada. A three-wave longitudinal design was employed among nursing students. Nurses were surveyed before they entered the labor market, and then twice after they started working. Participants were contacted by post at their home address. The hypotheses were tested using structural equation modeling. Professional commitment explains why good work characteristics and the provision of organizational resources related to patient care reduce nurses' anxiety and physical symptoms, and increase their professional turnover intentions. Pre-entry professional perceptions moderate the effects of work characteristics on professional commitment such that when participants hold positive pre-entry perceptions about the profession, the propensity to develop professional commitment is higher. There is a worldwide shortage of nurses. From a nurse training perspective, it is important to create realistic perceptions of the nursing role. In hospitals, providing a good work environment and resources conducive to their professional ethos is critical for ensuring nurses do not leave the profession early on in their careers. © 2017 Sigma Theta Tau International.

Meara, Michael P; Schlitzkus, Lisa L; Witherington, Mitzi; Haisch, Carl; Rotondo, Michael F; Schenarts, Paul J

2010-01-01

The current recession has impacted all aspects of our economy. Some residency programs have experienced faculty salary cuts, furlough days, and cessation of funding for travel to academic meetings. This milieu forced many residency programs to reevaluate their commitment to resident education, particularly for those expenses not provided for by Direct Medical Education (DME) and Indirect Medical Education (IME) funds. The purpose of this study was to determine what price a Department of Surgery pays to fulfill its commitment to resident education. A financial analysis of 1 academic year was performed for all expenses not covered by DME or IME funds and is paid for by the faculty practice plan. These expenses were categorized and further analyzed to determine the funds required for resident-related scholarly activity. A university-based general surgery residency program. Twenty-eight surgical residents and a program coordinator. The departmental faculty provided $153,141 during 1 academic year to support the educational mission of the residency. This amount is in addition to the $1.6 million in faculty time, $850,000 provided by the federal government in terms of DME funds, and $14 million of IME funds, which are distributed on an institutional basis. Resident presentations at scientific meetings accounted for $49,672, and program coordinator costs of $44,190 accounted for nearly two-thirds of this funding. The departmental faculty committed $6400 per categorical resident. In addition to DME and IME funds, a department of surgery must commit significant additional monies to meet the educational goals of surgical residency.

Hendel, Tova; Kagan, Ilya

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.

INTRODUCE: The changes in the health area and the set of structural changes in the nursing profession and career interfere in the dynamics and stability of the future of the nurses. To study the influence of organizational and professional commitment of the nurses in the strategies of conflict resolution. This is a quantitative, transversal and non-experimental research, following a descriptive-correlational way. Non-probabilistic sample of 102 nurses to perform duties in Health Units, mostly female (82.4%) with a mean age of 39.33 years and standard deviation 9.226. The measuring instrument consists of three scales calibrated and validated for the portuguese population: Organizational Commitment Questionnaire, Professional Commitment Scale and Inventory Strategies for Conflict Resolution, which assesses how individuals deal with conflict situations before higher (Form A), subordinate (Form B) and colleagues (Form C). Nurses demonstrate a moderate organizational commitment and higher affective commitment and normative commitment to the instrumental. Nurses demonstrate a moderate professional commitment and the results show that nurses have higher values on the dimensions of that interest and challenge the relevance dimension of nursing as a profession. The organizational commitment influences the adoption of strategies of conflict resolution as a conflict situation arises with the boss, subordinates or colleagues. The higher the level of organizational commitment higher the level of professional commitment. Nurses more engaged professionally demonstrate strategies that use more integrative and compromise in conflict resolution whether against the boss, subordinates or colleagues. The results ensure the need to promote and stimulate the affective commitment by the positive consequences it entails the organization and the profession. The organizational performance benefits from the stimulation of the conflict under certain conditions and that the constructive

Objective Burnout syndrome can significantly reduce the performance of health workers. Although many factors have been identified as antecedents of burnout, few studies have investigated the role of organisational commitment in its development. The purpose of the present study was to examine the relationships between subdimensions of burnout syndrome (emotional exhaustion, depersonalisation and personal accomplishment) and subdimensions of organisational commitment (affective commitment, continuance commitment and normative commitment). Methods The present study was a cross-sectional survey of physicians and other healthcare employees working in the Ministry of Health Ordu University Education and Research Hospital. The sample consisted of 486 healthcare workers. Data were collected using the Maslach Burnout Inventory and the Organisation Commitment Scale, and were analysed using the canonical correlation approach. Results The first of three canonical correlation coefficients between pairs of canonical variables (Ui , burnout syndrome and Vi, organisational commitment) was found to be statistically significant. Emotional exhaustion was found to contribute most towards the explanatory capacity of canonical variables estimated from the subdimensions of burnout syndrome, whereas affective commitment provided the largest contribution towards the explanatory capacity of canonical variables estimated from the subdimensions of organisational commitment. Conclusions The results of the present study indicate that affective commitment is the primary determinant of burnout syndrome in healthcare professionals. What is known about the topic? Organisational commitment and burnout syndrome are the most important criteria in predicting health workforce performance. An increasing number of studies in recent years have clearly indicated the field's continued relevance and importance. Conversely, canonical correlation analysis (CCA) is a technique for describing the relationship

Employee commitment and motivation: a conceptual analysis and integrative model.

Science.gov (United States)

Myer, John P; Becker, Thomas E; Vandenberghe, Christian

2004-12-01

Theorists and researchers interested in employee commitment and motivation have not made optimal use of each other's work. Commitment researchers seldom address the motivational processes through which commitment affects behavior, and motivation researchers have not recognized important distinctions in the forms, foci, and bases of commitment. To encourage greater cross-fertilization, the authors present an integrative framework in which commitment is presented as one of several energizing forces for motivated behavior. E. A. Locke's (1997) model of the work motivation process and J. P. Meyer and L. Herscovitch's (2001) model of workplace commitments serve as the foundation for the development of this new framework. To facilitate the merger, a new concept, goal regulation, is derived from self-determination theory (E. L. Deci & R. M. Ryan, 1985) and regulatory focus theory (E. I. Higgins, 1997). By including goal regulation, it is acknowledged that motivated behavior can be accompanied by different mindsets that have particularly important implications for the explanation and prediction of discretionary work behavior. 2004 APA, all rights reserved

A model hypothesizing differential relationships among predictor variables and individual commitment to the organization and work team was tested. Data from 485 members of sewing teams supported the existence of differential relationships between predictors and organizational and team commitment. In particular, intersender conflict and satisfaction with coworkers were more strongly related to team commitment than to organizational commitment. Resource-related conflict and satisfaction with supervision were more strongly related to organizational commitment than to team commitment. Perceived task interdependence was strongly related to both commitment foci. Contrary to prediction, the relationships between perceived task interdependence and the 2 commitment foci were not significantly different. Relationships with antecedent variables help explain how differential levels of commitment to the 2 foci may be formed. Indirect effects of exogenous variables are reported.

Policy implications of considering pre-commitments in U.S. aggregate energy demand system

International Nuclear Information System (INIS)

Rowland, Christopher S.; Mjelde, James W.; Dharmasena, Senarath

2017-01-01

Linear approximations of the Generalized Almost Ideal Demand System and Almost Ideal Demand System for U.S. energy are compared to contrast the explicit inclusion and exclusion of pre-committed consumption levels. Results indicate that pre-commitment levels, the quantity of a good that is consumed in the short run with little regard for price, helps to better explain energy demand in the U.S. compared to the system that does not explicitly consider pre-commitments. Policy implications are if pre-commitments are a legitimate assumption, larger price changes are necessary to achieve a given policy objective than if there are no pre-commitments. - Highlights: • Pre-commitments are the quantity that is consumed with little regard for price. • Demand systems with pre-commitment levels better explain energy demand. • Elasticities from assuming pre-commitments are more elastic. • Estimated elasticities apply to discretionary and not pre-commitment consumption. • Pre-commitments require larger price changes to achieve a given policy objective.

Science.gov (United States)

Tsai, Yafang; Wu, Shih-Wang

2011-12-01

The purpose of this article was to explore the structural relationships among internal marketing, organizational commitment and service quality and to practically apply the findings. Internal marketing is a way to assist hospitals in improving the quality of the services that they provide while executing highly labour-intensive tasks. Through internal marketing, a hospital can enhance the organizational commitment of its employees to attain higher service quality. This research uses a cross-sectional study to survey nursing staff perceptions about internal marketing, organizational commitment and service quality. The results of the survey are evaluated using equation models. The sample includes three regional hospitals in Taiwan. Three hundred and fifty questionnaires were distributed and 288 valid questionnaires were returned, yielding a response rate of 82.3%. The survey process lasted from 1 February to 9 March 2007. The data were analysed with SPSS 12.0, including descriptive statistics based on demographics. In addition, the influence of demographics on internal marketing, organizational commitment and service quality is examined using one-way anova. The findings reveal that internal marketing plays a critical role in explaining employee perceptions of organizational commitment and service quality. Organizational commitment is the mediator between internal marketing and service quality. The results indicate that internal marketing has an impact on both organizational commitment and service quality. Internal marketing should be emphasized to influence frontline nursing staff, thereby helping to create better organizational commitment and service quality. © 2011 The Authors.

Full Text Available The research was done with the purpose of identifying the relationship between two conceptual structures which were organizational learning and organizational commitment. Main hypothesis was identified as “There is a positive correlation between employees’ organizational learning inclination and organizational commitment.” In order to identify the relation between two conceptual structures, Likert type scale was used by using the literature. Stated likert type scales were applied for 279 people including managers’ and employees’ and statistical analysis on gathered datas from 260 questionnaires was done. In the research, both the correlation between organizational learning and sub-dimensions of organizational commitment which classified as emotional, normative, continuance commitment and the correlation between employees’ age, level of education, position and working period variables and organizational commitment were examined. Regression analysis was used in order to identify the correlation between organizational learning and organizational commitment which was the main hypothesis. Other hypotheses were tested by one way analysis of variance. It was found that that there was a positive correlation between organizational learning and organizational commitment. Result of the analysis indicates that in order to increase organizational learning inclination of managers and employees for developing their organizational commitment, applications for organizational learning should be given importance in companies.

Job sharing: a retention strategy for nurses.

Kane, D

1999-01-01

Job sharing is a part-time employment alternative which offers advantages for employers interested in retaining experienced staff and nurses who are seeking a more equitable balance between work life and home life responsibilities. This quasi experimental, ex post facto research study was designed to determine if there are differences in job satisfaction, burnout, and desire to leave their position, in nurses who are employed in full-time, part-time, or job sharing positions. The sample (N = 269) was drawn from a large Canadian teaching and referral hospital. Three sample groups were developed, consisting of job sharing, full-time, and part-time nurses, respectively. Descriptive statistics were used to identify characteristics of the selected population. Analysis of variance was used to examine differences between the three employment groups on the outcome measures of job satisfaction, burnout, and desire to leave their position. The results of this study significantly support the belief that job sharing has a positive impact on job satisfaction and job retention. Implications for nursing administrators as well as individual nurses will be discussed.

The authors examined whether commitment to emotional display rules is a necessary condition for emotional display rules to affect behavior at work. Results using structural equation modeling revealed that display rule commitment moderated the relationships of emotional display rule perceptions with surface acting, deep acting, and positive affective delivery at work, such that the relationships were strong and positive when commitment to display rules was high and weak when commitment to display rules was low. These findings suggest that motivation plays a role in the emotional labor process in that individuals must be committed to display rules for these rules to affect behavior.

2016-08-01

Full Text Available Internet pornography has many adverse effects, especially to the relationship commitment. The use of pornography directly correlates to a decrease in sexual intimacy. Hence, this might lead to weakening of the relationship of their partner. To find out the relevance of the claim, the researchers aimed to explore the relationship of Internet pornography consumption to the relationship commitment of married individuals in the Philippines. Different factors such as level of satisfaction, investment, quality of alternatives, relationship stability and viewing habits were also considered in determining the relationship of watching online pornography and the relationship commitment of Filipino married individuals. The study used the descriptive-correlational design. A self-administered survey was distributed to 400.It is revealed that Internet pornography consumption has an adverse effect on the relationship commitment of married Filipino couples. Furthermore, watching porn online weakened the relationship commitment that leads to an unstable relationship. This investigation found out that internet pornography consumption has a nominal negative effect on the relationship commitment of Filipino married individuals. It is proven on this study that internet pornography consumption can weaken the relationship commitment of married individuals thus, it promotes knowledge about numerous effect of it, negatively and even positively.

Suppose that Alice and Bob define their coordinate axes differently, and the change of reference frame between them is given by a probability distribution μ over SO(3). We show that this uncertainty of reference frame is of no use for bit commitment when μ is uniformly distributed over a (sub)group of SO(3), but other choices of μ can give rise to a partially or even arbitrarily secure bit commitment

Talent is the core competitiveness of an enterprise, how to retain talent, inspire their creative, exert its advantages for the enterprise to bring profit maximization and value appreciation. It has always been the focus of enterprises and scholars. A great number of studies have shown that organizational commitment has an important impact on employees’ attitudes, thoughts and behaviors, and leadership style is also an important variable which affects the organizational commitment of employees. Through the questionnaire survey, the statistical software SPSS24.0 empirical analysis of the collected data shows that there is a positive correlation between the style of leadership and the commitment of the employee and the correlation with the employee’s normative commitment is not significant; The established leadership is negatively correlated with the employee’s emotional commitment and normative commitment, but it is not significant with the continuous commitment.

 The paper draws attention to: i) key considerations involving the confidentiality, privacy, and security of shared data; and ii) the requirements needed to build collaborative arrangements encompassing all stakeholders with the goal of ensuring safe, secure, and quality use of shared data.  A narrative review of existing research and policy approaches along with expert perspectives drawn from the International Medical Informatics Association (IMIA) Working Group on Technology Assessment and Quality Development in Health Care and the European Federation for Medical Informatics (EFMI) Working Group for Assessment of Health Information Systems.  The technological ability to merge, link, re-use, and exchange data has outpaced the establishment of policies, procedures, and processes to monitor the ethics and legality of shared use of data. Questions remain about how to guarantee the security of shared data, and how to establish and maintain public trust across large-scale shared data enterprises. This paper identifies the importance of data governance frameworks (incorporating engagement with all stakeholders) to underpin the management of the ethics and legality of shared data use. The paper also provides some key considerations for the establishment of national approaches and measures to monitor compliance with best practice. Data sharing endeavours can help to underpin new collaborative models of health care which provide shared information, engagement, and accountability amongst all stakeholders. We believe that commitment to rigorous evaluation and stakeholder engagement will be critical to delivering health data benefits and the establishment of collaborative models of health care into the future.

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.

Characteristics of a direct methanol fuel cell system with the time shared fuel supplying approach

International Nuclear Information System (INIS)

Na, Youngseung; Kwon, Jungmin; Kim, Hyun; Cho, Hyejung; Song, Inseob

2013-01-01

DMFC (direct methanol fuel cell) systems usually employ two pumps for supplying the methanol solution. The conventional system configuration, however, may bring about free flow from the methanol reservoir and malfunctions in the self-priming of the pumps. When instruments such as check valves and pressure regulators are applied, they result in excessive weight and control system malfunctions. In this paper, a light and robust DMFC system is proposed. By using the time sharing approach to supply fuel with a 3-way valve, free flow does not occur because only one inlet is opened at one time which means that both the circulation flow from gas liquid separator and the fuel flow from the methanol cartridge are not allowed to be opened at same time. As a result, back flow and self-priming problems do not occur. This makes the system stable and robust due to the removal of both the check valves and the fluctuation from unstable back pressure. Stabilized system doesn't need excessive battery buffering and recycling water any more, which are responsible for the heavy system. The proposed system performs the same level of power and efficiency with the conventional system. Adaptability is also carried out in various environmental temperature conditions. - Highlights: ►A light and robust DMFC system is proposed. ► The circulation pump is able to self-prime by itself after long term storage. ► The time sharing approach to supply fuel enables to control the methanol concentration precisely. ► The methanol concentration is controlled without free flow and the back flow from the fuel feeding pump. ► The excessive buffer of the batteries and the recycling water level are reduced

Maxwell, J.; Briscoe, F.; Suzuki, Tatsujiro; Lee, J.; Stewart, A.

1997-01-01

Large organizations often escalate their commitments to mega-project development, even after evidence becomes available of adverse environmental consequences or lack of economic feasibility. This escalation of commitment transcends both sectorial and national boundaries. Preeminent examples include controversial nuclear projects in the US, hydroelectric projects like the Three Gorges Dam in China, and transport projects like the Chunnel and the Concorde. In this article, the authors examine the experience of Hydro-Quebec with the Great Whale Project. They argue that Hydro-Quebec escalated its commitment even after serious questions emerged about its environmental impacts and economic feasibility, because of (1) its earlier success with large projects, (2) its engineering culture''s norms for consistency, and (3) its role in the government''s desire for economic and cultural autonomy. Finally, they discuss the changes that are necessary to break commitments to such projects

Real-time sharing of gaze data between multiple eye trackers-evaluation, tools, and advice.

Technological advancements in combination with significant reductions in price have made it practically feasible to run experiments with multiple eye trackers. This enables new types of experiments with simultaneous recordings of eye movement data from several participants, which is of interest for researchers in, e.g., social and educational psychology. The Lund University Humanities Laboratory recently acquired 25 remote eye trackers, which are connected over a local wireless network. As a first step toward running experiments with this setup, demanding situations with real time sharing of gaze data were investigated in terms of network performance as well as clock and screen synchronization. Results show that data can be shared with a sufficiently low packet loss (0.1 %) and latency (M = 3 ms, M A D = 2 ms) across 8 eye trackers at a rate of 60 Hz. For a similar performance using 24 computers, the send rate needs to be reduced to 20 Hz. To help researchers conduct similar measurements on their own multi-eye-tracker setup, open source software written in Python and PsychoPy are provided. Part of the software contains a minimal working example to help researchers kick-start experiments with two or more eye trackers.

Interrupting behaviour: Minimizing decision costs via temporal commitment and low-level interrupts

Dayan, Peter

2018-01-01

Ideal decision-makers should constantly assess all sources of information about opportunities and threats, and be able to redetermine their choices promptly in the face of change. However, perpetual monitoring and reassessment impose inordinate sensing and computational costs, making them impractical for animals and machines alike. The obvious alternative of committing for extended periods of time to limited sensory strategies associated with particular courses of action can be dangerous and wasteful. Here, we explore the intermediate possibility of making provisional temporal commitments whilst admitting interruption based on limited broader observation. We simulate foraging under threat of predation to elucidate the benefits of such a scheme. We relate our results to diseases of distractibility and roving attention, and consider mechanistic substrates such as noradrenergic neuromodulation. PMID:29338004

Full Text Available In the past three decades, organizational commitment has been of interest to researchers as one of the organizational attitudes. The aim of this study was to investigate the relationship of emotional intelligence and personality traits with organizational commitment among Iranian nurses. A total of 280 nurses were selected by multistage random sampling. Study tools included emotional intelligence inventory, Neo personality inventory and organizational commitment inventory. Results showed the positive and significant relationship of emotional intelligence and its dimensions (self-expression, self-regard, independence, social responsibility, problem solving, stress tolerance, impulse control, and optimism with organizational commitment. Also, organizational commitment showed a positive and significant relationship with extroversion and conscientiousness. Moreover, components of self-expression, problem solving and stress tolerance in emotional intelligence are able to predict organizational commitment. Thus, these results indicate the importance of emotional intelligence and personality traits in organizational commitment.

Full Text Available The article investigates the relationship between commitment to business ethics and nonfinancial business performance. Data of commitment to business ethics and nonfinancial business performance were collected from 100 participants through a questionnaire survey. The survey was conducted in 2015 in Croatian large and medium sized companies. The questionnaire for assessing commitment to business ethics contained nine different dimensions while the nonfinancial business performance contained three dimensions: client satisfaction, human resource management plus innovativeness and efficiency of business processes. Multiple regression methods were applied in the analysis. The empirical results of three multiple linear regression models show that certain dimension of commitment to business ethics had a positive influence on the nonfinancial performance of the companies. Motivation and rewarding policy for ethical behavior and responding to unethical behavior, as a dimension of commitment to business ethics, has distinctive effects on all three nonfinancial performance dimensions. It was also found that selecting suppliers based on the standards of ethics and compliance has a positive and strong influence on client satisfaction while using ethical criteria in the performance and efficiency evaluation of employees has a positive and significant influence on innovativeness and efficiency of business processes. This research leads to the conclusion that some dimensions of commitment to business ethics can be important predictors of nonfinancial business performance. Therefore, results of the research could be considered as valid motivation for further improvement of commitment to ethics in the business environment.

Employee commitment to the organization is a crucial issue in today's health-care market. In Iran, few studies have sought to evaluate the factors that contribute to forms of commitment. The aim of this study was to investigate the relationship between nurses' organizational commitment, work environment conditions, and life satisfaction. A cross-sectional design was utilized. Questionnaires were distributed to all the staff nurses who had permanent employment (with at least 2 years of experience in nursing) in the five hospitals affiliated to Birjand Medical Sciences University. Two hundred and fifty participants returned completed questionnaires. Most were female and married. The correlation of the total scores of nurses' affective organizational commitment and work environment conditions indicated a significant and positive relationship. Also, a statistically significant relationship was found between affective organizational commitment and life satisfaction. The implementation of a comprehensive program to improve the work conditions and life satisfaction of nurses could enhance their organizational commitment.

Many factors influence the organizational commitment of employees. One of these factors is job designing since it affects the attitude, beliefs, and feelings of the organization employees. We aimed to determine the relationship between job characteristics and organizational commitment among the employees of hospitals. In this descriptive and correlational study, 152 Iranian employees of the hospitals (physicians, nurses, and administrative staff) were selected through stratified random sampling. Data gathered using 3-part questionnaire of "demographic information", "job characteristics model," and "organizational commitment," in 2011. Study data were analyzed using SPSS v. 16. There was significant statistical correlation between organizational commitment and variables of educational level (P = 0.001) and job category (P = 0.001). Also, a direct and significant correlation existed between motivating potential score and job feedback on one hand and organizational commitment on the other hand (P = 0.014). According to the results, managers of the hospitals should increase staff's commitment through paying attention to proper job designing.

issues regarding the relationship of three concepts in the study. According to the findings, if the organizational climate scores of the employees are high, organizational commitment scores of the employees are high at the same time. In other words, if the employees in public hospitals of North Cyprus perceive the organizational climate in a positive way, they will have higher levels of organizational commitment. Findings suggested that organizational climate is an important factor in healthcare settings in terms of employee commitment and how employees perceive organizational performance, which would lead to significant results about the provision of service in healthcare organizations.
