BFT Hamiltonian embedding for SU(3) Skyrmion

We newly apply the Batalin, Fradkin and Tyutin (BFT) formalism to the SU(3) flavor Skyrmion model to investigate the Weyl ordering correction to the structure of the hyperfine splittings of strange baryons. On the other hand, the Berry phases and Casimir effects are also discussed.Comment: 14 pages, modified titl

TWINLATIN: Twinning European and Latin-American river basins for research enabling sustainable water resources management. Combined Report D3.1 Hydrological modelling report and D3.2 Evaluation report

Water use has almost tripled over the past 50 years and in some regions the water demand already exceeds supply (Vorosmarty et al., 2000). The world is facing a “global water crisis”; in many countries, current levels of water use are unsustainable, with systems vulnerable to collapse from even small changes in water availability. The need for a scientifically-based assessment of the potential impacts on water resources of future changes, as a basis for society to adapt to such changes, is strong for most parts of the world. Although the focus of such assessments has tended to be climate change, socio-economic changes can have as significant an impact on water availability across the four main use sectors i.e. domestic, agricultural, industrial (including energy) and environmental. Withdrawal and consumption of water is expected to continue to grow substantially over the next 20-50 years (Cosgrove & Rijsberman, 2002), and consequent changes in availability may drastically affect society and economies. One of the most needed improvements in Latin American river basin management is a higher level of detail in hydrological modelling and erosion risk assessment, as a basis for identification and analysis of mitigation actions, as well as for analysis of global change scenarios. Flow measurements are too costly to be realised at more than a few locations, which means that modelled data are required for the rest of the basin. Hence, TWINLATIN Work Package 3 “Hydrological modelling and extremes” was formulated to provide methods and tools to be used by other WPs, in particular WP6 on “Pollution pressure and impact analysis” and WP8 on “Change effects and vulnerability assessment”. With an emphasis on high and low flows and their impacts, WP3 was originally called “Hydrological modelling, flooding, erosion, water scarcity and water abstraction”. However, at the TWINLATIN kick-off meeting it was agreed that some of these issues resided more appropriately in WP6 and WP8, and so WP3 was renamed to focus on hydrological modelling and hydrological extremes. The specific objectives of WP3 as set out in the Description of Work are

Job crafting, employee well-being, and quality of care

The main objective is to study the effects of job crafting activities of elder care and nursing home employees on their perceived well-being and quality of care in two European countries, Spain and Sweden. The Job Crafting, the General Health, and the Quality of Care questionnaires were administered to 530 employees. Correlations and hierarchical regression analyses were performed. Results confirm the effects of job crafting on quality of care (r = .291, p < .01; β = .261, p < .01; ΔR 2 = .065, p < .01) and employees' well-being (r = .201, p < .01; β = .171, p < .01; ΔR 2 = .028, p < .01). A positive linear relationship was found between job crafting and well-being in Spain and Sweden and with quality of care in Spain. On the contrary, in Sweden, the relationship between job crafting and well-being was not linear. Job crafting contributes significantly to employees' and residents' well-being. Management should promote job crafting to co-create meaningful and productive work. Cultural effects are proposed to explain the differences found

Spanish and Swedish eldercare managers' influence on employees

Purpose - Hierarchical and flat organizational types are predominant in Spain and Sweden, respectively. To study how managers' commitment and work overcommitment (WOC) affect employee well-being, and job perception in these different countries can shed insight on how to improve eldercare organization. The purpose of this paper was to study the association between eldercare employee exposure to managers' commitment and WOC, and employee mental well-being and job perception and how these associations differed between Spain and Sweden. Design/methodology/approach - A questionnaire with validated questions on commitment, WOC, mental well-being and job perception, operationalized as the perception of quality of care and turnover intent, was sent out to eldercare managers and employees in Spain and Sweden. t-Tests, χ2 and linear regression were applied to study the associations and differences between the countries. Findings - Interaction analyses revealed that Spanish employees' mental well-being and job perception were influenced by their managers' commitment and WOC in that manager commitment improved and WOC impaired well-being and job perception. However, the Swedish eldercare employees were not influenced by their managers on these parameters. Practical implications - The impact of managerial commitment and WOC differed between employees in Spain and Sweden, possibly because the preconditions for leadership varied due to differences in organizational type. Originality/value - This study compares the managers' impact on employee health and job perception in two countries with different organizational prerequisites. Moreover, managers' commitment and WOC were estimated by the managers themselves and did not rely on the employees' perception, which improved ecological validit

Cognitive job crafting as mediator between behavioral job crafting and quality of care in residential homes for the elderly

Extending previous studies on job crafting, the aim of the present study is to analyze the effect of job crafting on quality of care in residential homes for elderly people in two European countries (Spain and Sweden). We hypothesize that cognitive crafting could be a consequence of behavioral crafting and that it will mediate the relationship between behavioral crafting and the perception of quality of care. A correlational design was used, with two waves approximately 12 months apart (n = 226). Our results indicate that behavioral job crafting at T1 had an effect on cognitive job crafting at T2, relational job crafting at T1increases quality of care at T2, and the mediation effect of cognitive job crafting. These results indicate that we must differentiate between the two forms of crafting (behavioral and cognitive), not as indicators of the same latent construct, but as aggregates. Additionally, we point out two main implications for managerial practice. First, as relational job crafting has a direct effect on quality of care, it is important to assure an organizational culture oriented towards employees. Secondly, due to the mediation effect of cognitive job crafting, managers should facilitate meaningful work environments. To do so, jobs should be re-designed, increasing skills variety, identity and significance

Organizational change and commitment: Effects on well-being, turnover intent and quality of care in Spanish and Swedish eldercare

Frequent organizational changes have been a rule rather than an exception in many European countries for decades. The present study investigates how affective organizational commitment relates to and moderates the effects of having been exposed to organizational restructuring on employee well-being, quality of care and turnover intentions among 530 eldercare employees in Sweden and Spain. The results show that there was a main effect of employees' experiences of being affected by change on well-being and turnover intentions but not on quality of care. Restructuring changes were moderated by affective commitment on turnover intentions. However, the buffering effect of affective commitment in terms of protecting employees from turnover intentions was weak

Cold wind of change: Associations between organizational change, turnover intention, overcommitment and quality of care in Spanish and Swedish eldercare organizations

Aim: To examine the association between organizational change, turnover intentions, overcommitment, and perceptions of quality of care among nurses and nursing assistants employed in older people care organizations. Design: A longitudinal survey (baseline, 12 month follow-up) was used. Methods: A panel sample of 226 older people care employees in Spain and Sweden responded to survey questions concerning organizational change, turnover intentions, overcommitment, and perceptions of quality of care. The data was analysed using structural equational modelling. Results: We found a statistically significant positive relationship between organizational change, employees' turnover intention, and overcommitment. We also found a statistically significant negative relationship between organizational change and perceived quality of care

Job crafting and well-being in the elderly care sector: the effect of over-commitment

Purpose - The purpose of this paper is to analyze the moderation effect of over-commitment in the job crafting - well-being relationship, in the elderly care sector in Spain. Design/methodology/approach - A cross-sectional design was implemented and a final sample of 353 participants were assessed using the Job Crafting Questionnaire, an adaptation of the Over-commitment Scale from the Effort-Reward Imbalance Questionnaire, and the General Health Questionnaire (GHQ-12). Findings - A positive interaction between relational and task crafting and over-commitment is observed in the prediction of well-being levels. Specifically, the effect of over-commitment in the task crafting - well-being relationship proved to be statistically significant when opposed to low, medium and high levels of over-commitment. Additionally, the effect of over-commitment in the relational crafting - well-being relationship proved to be statistically significant only when opposed to medium and high levels of over-commitment. Finally, a direct and simple effect was observed between cognitive crafting and well-being, not moderated by over-commitment. Research limitations/implications - Implementation of non-behavioral measurements, and a non-longitudinal design are suggested. The development of behavioral measures for job crafting is encouraged, along with the implementation of longitudinal designs sensitive to changes in over-commitment. Possible over-commitment results are biased by an economically contracted environment. Practical implications - Job crafting training, over-commitment early detection and further research on job crafting strategies ' preferences are suggested. Originality/value - The moderating role of over-commitment in the job crafting - well-being relationship in the elderly care sector represents one of these attempts to better understand evidences of how work-related efforts modify a worker ' s psychological functioning and adaptation, which is the reason why, specially in contexts of uncertainty, its study becomes relevant

Kaon Condensation in the Bound-State Approach to the Skyrme Model

We explore kaon condensation using the bound-state approach to the Skyrme model on a 3-sphere. The condensation occurs when the energy required to produce a $K^-$ falls below the electron fermi level. This happens at the baryon number density on the order of 3--4 times nuclear density.Comment: LaTeX format, 15 pages. 3 Postscript figures, compressed and uuencode
