Can organizational commitment be experienced by indivuals pursuing contemporary career paths?

In a context in which organizations can no longer promise life-time employment and individuals increasingly experience inter-organizational mobility, this study tackles the question of whether organizational commitment is no longer related to new career orientations. To this end, it analyzes the relation between the underlying dimensions of protean (self direction and values driven) and boundaryless (boundaryless mindset and organizational mobility preference) career attitudes (Briscoe et al., 2006) and organizational commitment, within today's unstable and uncertain business scenario. Research results suggest that protean career attitudes contribute significantly to individuals emotional attachment to their employing organization. Furthermore, organizational mobility preference was found to be significant in predicting both affective and continuance commitment. Finally, future research suggestions and practical implications associated with the current study are provided.

Content validation of the dimensions constituting non-adherence to treatment of arterial hypertension

The objective of the study was to validate the content of the dimensions that constituted nonadherence to treatment of arterial systemic hypertension. It was a methodological study of content validation. Initially an integrative review was conducted that demonstrated four dimensions of nonadherence: person, disease/treatment, health service, and environment. Definitions of these dimensions were evaluated by 17 professionals, who were specialists in the area, including: nurses, pharmacists and physicians. The Content Validity Index was calculated for each dimension (IVCi) and the set of the dimensions (IVCt), and the binomial test was conducted. The results permitted the validation of the dimensions with an IVCt of 0.88, demonstrating reasonable systematic comprehension of the phenomena of nonadherence.

The State of the Immigrant Body and the Body of the State: Negotiations at the Interface

Using an ethnographic analysis of the social interfaces between state agents and Cape Verdean students in Portugal, observed through participant observation in medical appointments, social work, immigration services and legal support to immigrants, this article aims to examine disciplinary state practices and the negotiations and power struggles that take place. The ethnographic cases discussed demonstrate how the idea of a fair and neutral state is simultaneously reproduced and denied in practice, thus elucidating the state as a symbol of union of an effective disunity. The ethnographic examples also indicate other dimensions of state practice, besides micro-disciplinary powers, which create room for flexibility and adaptation. And it is in this sense that ethnographies of interfaces between state and citizen offer a more relative perspective of excessively systematic interpretations of governmentality, illustrating how the effects of contradictory state practices are as unpredictable as human action itself.

Secular changes of spinal canal dimensions in Western Switzerland: a narrowing epidemic?

STUDY DESIGN: Computed tomography-based anatomical study. OBJECTIVE: To study the secular changes in lumbar spinal canal dimensions. SUMMARY OF BACKGROUND DATA: Development of symptomatic lumbar spinal stenosis, among other factors, is related to the dimensions of the bony canal. The canal reaches its adult size early on in life. Several factors, including protein intake, may influence its final dimensions. As with increases in human stature from improvements of socioeconomic conditions, we hypothesized that adult bony canal size has also grown larger in recent generations. METHODS: This study analyzes computed tomographic reconstructions from 184 subjects performed for either trauma (n = 81) or abdominal pathologies (n = 103) and born either between 1940 and 1949 (n = 88) or 1970 and 1979 (n = 96). The cross-sectional area of the bony canal was digitally measured at the level of the pedicle (i.e., at a level not influenced by degenerative changes) for each lumbar vertebra. Intra- and interobserver reliability was assessed. RESULTS: Intra- and interobserver measurement reliability were excellent (interclass correlation coefficient = 0.87) and good (interclass correlation coefficient = 0.61), respectively. Contrary to our hypothesis, the 1940-1949 generation patient group exhibited larger lumbar canals at all levels as compared with the 1970-1979 group. Statistically this difference was highly significant (P < 0.001) and particularly pronounced in the trauma subgroup. CONCLUSION: Given that human stature evolution has stabilized and adult height is established during the first 2 years of long bone growth, it is possible that antenatal factors are responsible for this surprising finding. Maternal smoking and age may be possible explanations. This finding may have significant implications. An increasing number of patients may emerge with lumbar spinal stenosis as degenerative changes develop, putting a strain on health resources. Further studies in different population groups and countries will be important to further confirm this trend. LEVEL OF EVIDENCE: 3.

Gender, age, and body surface area are the major determinants of ascending aorta dimensions in subjects with apparently normal echocardiograms.

BACKGROUND: Limited data have been published on the normal size of the ascending aorta (AA) measured using transthoracic echocardiography (TTE). METHODS: AA diameters were measured in 1799 patients with normal cardiac findings on TTE and compared with the diameters of the sinus of Valsalva (SoV). RESULTS: Mean diameters in men and women, respectively, were 3.4 and 3.1 cm for the SoV and 3.2 and 3.0 cm for the AA. The sizes of the SoV and the AA showed strong correlations with age, age squared, and body surface area. The 5th and 95th percentile curves for the SoV and AA showed faster growth of diameters in early adulthood compared with old age. The dimensions of the SoV were larger than those of the AA (mean differences, 0.19 cm in men and 0.08 cm in women), and the difference between the SoV and AA was negatively correlated with age. CONCLUSION: The findings of this study stress the importance of indexing dimensions of the SoV and the AA to age and body surface area separately for men and women.

Involuntary treatment of alcohol-dependent patients: a study of 17 consecutive cases of civil commitment.

AIM: To investigate the baseline and follow-up characteristics of a group of alcohol-dependent patients being treated under civil commitment. METHODS: This study involved a cross-sectional comparative analysis of baseline characteristics and a follow-up survey of a group of committed alcoholic patients. The study was undertaken in the Alcohol Unit of a 1,000-bed general and university hospital. The study included 17 consecutive cases of civil commitment (representing 15 patients, of whom 2 were committed twice) and a comparative group of 34 randomly selected age- and sex-matched patients. Baseline characteristics of the cases (at the time of commitment) and of patients from the comparative group were collected from medical records, including sociodemographic data, medical condition, patterns of drinking and number and dates of previous treatments for alcohol-related problems. A structured follow-up interview of the cases provided information on their medical condition, social status, patterns of alcohol use, type and duration of residential treatment as well as their perceptions of commitment. RESULTS: During a 4-year period, our Unit referred 23 cases of alcohol-dependent patients (out of 367) to the Guardianship Authority, requesting civil commitment. On 17 occasions, patients were committed to residential treatment, including 2 patients who underwent commitment on two separate occasions, thus representing a total of 15 different patients. In comparison with age- and sex-matched patients seen at the Unit, the cases were characterized by multiple medical, social and psychological alcohol-related impairments. At the time of follow-up, 14 out of 15 patients were alive, among whom 10 agreed to be interviewed. Eight of these reported complete abstinence, whereas 9 considered their alcohol problem as less severe than before. The average duration of commitment was 29 weeks. The majority of patients retrospectively considered the measure as having been justified and useful. The patients' satisfaction with the decision to commit was higher among women than among men. Health-related quality of life at the time of follow-up, as assessed by the MOS 36-Item Short Form Health Survey questionnaire, was good on average and better than that usually reported by other cohorts of alcoholics undergoing treatment. CONCLUSIONS: The usefulness of residential civil commitment of certain severely impaired alcohol-dependent patients is underscored. This study suggests that civil commitment not only may save the lives of endangered patients but could also be a health-promoting measure that may sometimes allow for recovery from dependence. Unexpectedly, this measure was retrospectively well accepted by many patients, who considered the commitment decision as having been justified and useful.

Deposits of the sandy braided South Saskatchewan River: Implications for the use of modern analogs in reconstructing channel dimensions in reservoir characterization

Estimation of the dimensions of fluvial geobodies from core data is a notoriously difficult problem in reservoir modeling. To try and improve such estimates and, hence, reduce uncertainty in geomodels, data on dunes, unit bars, cross-bar channels, and compound bars and their associated deposits are presented herein from the sand-bed braided South Saskatchewan River, Canada. These data are used to test models that relate the scale of the formative bed forms to the dimensions of the preserved deposits and, therefore, provide an insight as to how such deposits may be preserved over geologic time. The preservation of bed-form geometry is quantified by comparing the Alluvial architecture above and below the maximum erosion depth of the modem channel deposits. This comparison shows that there is no significant difference in the mean set thickness of dune cross-strata above and below the basal erosion surface of the contemporary channel, thus suggesting that dimensional relationships between dune deposits and the formative bed-form dimensions are likely to be valid from both recent and older deposits. The data show that estimates of mean bankfull flow depth derived from dune, unit bar, and cross-bar channel deposits are all very similar. Thus, the use of all these metrics together can provide a useful check that all components and scales of the alluvial architecture have been identified correctly when building reservoir models. The data also highlight several practical issues with identifying and applying data relating to cross-strata. For example, the deposits of unit bars were found to be severely truncated in length and width, with only approximately 10% of the mean bar-form length remaining, and thus making identification in section difficult. For similar reasons, the deposits of compound bars were found to be especially difficult to recognize, and hence, estimates of channel depth based on this method may be problematic. Where only core data are available (i.e., no outcrop data exist), formative flow depths are suggested to be best reconstructed using cross-strata formed by dunes. However, theoretical relationships between the distribution of set thicknesses and formative dune height are found to result in slight overestimates of the latter and, hence, mean bankfull flow depths derived from these measurements. This article illustrates that the preservation of fluvial cross-strata and, thus, the paleohydraulic inferences that can be drawn from them, are a function of the ratio of the size and migration rate of bed forms and the time scale of aggradation and channel migration. These factors must thus be considered when deciding on appropriate length:thickness ratios for the purposes of object-based modeling in reservoir characterization.

Omaksujaluokkien välillä tunnistettiin lukuisia eroja eri ominaisuuksien suhteen.

Making Sense of Shared Leadership. A case study of leadership processes and practices without formal leadership structure in the team context

Leadership is essential for the effectiveness of the teams and organizations they are part of. The challenges facing organizations today require an exhaustive review of the strategic role of leadership. In this context, it is necessary to explore new types of leadership capable of providing an effective response to new needs. The presentday situations, characterized by complexity and ambiguity, make it difficult for an external leader to perform all leadership functions successfully. Likewise, knowledge-based work requires providing professional groups with sufficient autonomy to perform leadership functions. This study focuses on shared leadership in the team context. Shared leadership is seen as an emergent team property resulting from the distribution of leadership influence across multiple team members. Shared leadership entails sharing power and influence broadly among the team members rather than centralizing it in the hands of a single individual who acts in the clear role of a leader. By identifying the team itself as a key source of influence, this study points to the relational nature of leadership as a social construct where leadership is seen as social process of relating processes that are co-constructed by several team members. Based on recent theoretical developments concerned with relational, practice-based and constructionist approaches to the study of leadership processes, this thesis proposes the study of leadership interactions, working processes and practices to focus on the construction of direction, alignment and commitment. During the research process, critical events, activities, working processes and practices of a case team have been examined and analyzed with the grounded theory –approach in the terms of shared leadership. There are a variety of components to this complex process and a multitude of factors that may influence the development of shared leadership. The study suggests that the development process of shared leadership is a common sense -making process and consists of four overlapping dimensions (individual, social, structural, and developmental) to work with as a team. For shared leadership to emerge, the members of the team must offer leadership services, and the team as a whole must be willing to rely on leadership by multiple team members. For these individual and collective behaviors to occur, the team members must believe that offering influence to and accepting it from fellow team members are welcome and constructive actions. Leadership emerges when people with differing world views use dialogue and collaborative learning to create spaces where a shared common purpose can be achieved while a diversity of perspectives is preserved and valued. This study also suggests that this process can be supported by different kinds of meaning-making and process tools. Leadership, then, does not reside in a person or in a role, but in the social system. The built framework integrates the different dimensions of shared leadership and describes their relationships. This way, the findings of this study can be seen as a contribution to the understanding of what constitutes essential aspects of shared leadership in the team context that can be of theoretical value in terms of advancing the adoption and development process of shared leadership. In the real world, teams and organizations can create conditions to foster and facilitate the process. We should encourage leaders and team members to approach leadership as a collective effort that the team can be prepared for, so that the response is rapid and efficient.

An analogue of the logistic map in two dimensions

This is a sequel to our earlier work on the modulated logistic map. Here, we first show that the map comes under the universality class of Feigenbaum. We then give evidence for the fact that our model can generate strange attractors in the unit square for an uncountable number of parameter values in the range μ∞<μ<1. Numerical plots of the attractor for several values of μ are given and the self-similar structure is explicity shown in one case. The fractal and information dimensions of the attractors for many values of μ are shown to be greater than one and the variation in their structure is analysed using the two Lyapunov exponents of the system. Our results suggest that the map can be considered as an analogue of the logistic map in two dimensions and may be useful in describing certain higher dimensional chaotic phenomena.

A study on the organisational commitment of professionals with respect to various aspects of organisational socialisation

Organisational commitment of various groups of professionals seems to be moderated by the differences of the groups as well as of the socialisation experiences Demographic variable ‘age’ and the semi-structural variable ‘experience’ cause a difference in the level of commitment. Similarly, the professional and organisational differences moderate the level of commitment. From the point of view of the organisations, the socialisation experiences if differ can be used as tool to process and enhance the level of commitment of professionals of various groups.The ‘Socialisation effect’ does not depend on the professional or demographic differences. Socialisation level is moderated only by the organisational specialities. It is purely an organisational variable. However, the difference in the socialisation levels as found among the professionals can cause a significant difference in the levels of organisational commitment of professionals

Psychometric properties of the scale NBAS applied to preterm or low birth weight

Objective: to assess, in a randomized sample of measurements made with the NBAS scale, in preterm and / or low birth weight babies, some psychometric characteristics of the same as her construct validity and internal consistency. Materials and methods: we designed a study of assessment of Psychometric properties. From a study of cross-sectional measurements, there were made assessment of the statistic behavior of the items, individually and in their internal consistency, then, there were carried out, type exploratory and confirmatory factor analysis. Results: we find that, in the analysis of preterm or low birth weight babies, the scale remains largely, the overall structure of factors proposed since 1982, in relation to the dimensions of habituation, social interactive and complementary. The items that make up the dimensions of SNA and motor systems are integrated. Also, we found Cronbach alpha values for internal consistency, which reflects higher to medium correlation levels in the behavioral and reflex items. Conclusion: the NBAS scale reflects characteristics of construct validity and internal consistency, which credits it as a useful tool in clinical assessment of neurodevelopmental effects of preterm or low birth weight babies. It is necessary to analyze the structure of the scale when used for purposes of scientific research.

Health system context and implementation of evidence-based practices-development and validation of the Context Assessment for Community Health (COACH) tool for low- and middle-income settings

Background: The gap between what is known and what is practiced results in health service users not benefitting from advances in healthcare, and in unnecessary costs. A supportive context is considered a key element for successful implementation of evidence-based practices (EBP). There were no tools available for the systematic mapping of aspects of organizational context influencing the implementation of EBPs in low- and middle-income countries (LMICs). Thus, this project aimed to develop and psychometrically validate a tool for this purpose. Methods: The development of the Context Assessment for Community Health (COACH) tool was premised on the context dimension in the Promoting Action on Research Implementation in Health Services framework, and is a derivative product of the Alberta Context Tool. Its development was undertaken in Bangladesh, Vietnam, Uganda, South Africa and Nicaragua in six phases: (1) defining dimensions and draft tool development, (2) content validity amongst in-country expert panels, (3) content validity amongst international experts, (4) response process validity, (5) translation and (6) evaluation of psychometric properties amongst 690 health workers in the five countries. Results: The tool was validated for use amongst physicians, nurse/midwives and community health workers. The six phases of development resulted in a good fit between the theoretical dimensions of the COACH tool and its psychometric properties. The tool has 49 items measuring eight aspects of context: Resources, Community engagement, Commitment to work, Informal payment, Leadership, Work culture, Monitoring services for action and Sources of knowledge. Conclusions: Aspects of organizational context that were identified as influencing the implementation of EBPs in high-income settings were also found to be relevant in LMICs. However, there were additional aspects of context of relevance in LMICs specifically Resources, Community engagement, Commitment to work and Informal payment. Use of the COACH tool will allow for systematic description of the local healthcare context prior implementing healthcare interventions to allow for tailoring implementation strategies or as part of the evaluation of implementing healthcare interventions and thus allow for deeper insights into the process of implementing EBPs in LMICs.

Participação Cidadã na Gestão Pública: Estudo de Caso do Programa Favela-Bairro do Município do Rio de Janeiro

In the Brazilian political history, the power of the State was always associated to the classes that hold the production means. The state intervention to solve the lacks of the population induced the cooptation of the less favored classes, guaranteeing the continuity of the elites in the power and discouraging initiatives of the bases participation. The citizen participation is one of the analysis dimensions of the public power decision process and it must consist in a key dimension at the identification of solutions for the development. Through the evaluation of a municipal program addressed to the resident population in slums of medium load in Rio de Janeiro - the Programa Favela-Bairro - the study aims to verify, at the present time, if the participation remain an expression of the theoretical speech of the public administration or if it is understood as a social right. It intends to evaluate the mechanisms and the spaces of the communities dialogue with the public municipal managers. The field research consisted of interviews with social actors of the executive and municipal legislative, as well as with members of the organized civil society (inhabitants associations), community leaders and beneficiaries of the program, residents in the slum. The work raises the discussion about the necessary conditions to the public politics produce effective results, in terms of the human satisfaction, and to lead the social subjects to the understanding and learning of the active citizenship and democracy. It also intends to identify an evaluation methodology whose produced knowledge acts in the transformation of the society, reinforcing the critical researcher's paper, whose commitment is to study the reality and to point the roads that lead to the change in the social practice.
