As in other federal-like countries, intergovernmental relations in Spain are characterised by a series of conflicts between central and regional governments. But, which factors explain this dynamic of contention? This investigation operationalises intergovernmental conflicts through a specific dataset constituted by the volume of contestations between regional and central executives (and vice versa) in Spain before the Constitutional Court. This research demonstrates that from 1984 to 2014 the periods of absolute majority at the Congress and the victory of peripheral nationalist parties at the head of autonomous communities increased the level of intergovernmental contestations. 相似文献

We explore the intrinsic ambiguity of speaking up in a multinational healthcare subsidiary. A culture change initiative, emphasizing learning and agility through encouraging employees to speak up, gave rise to paradoxical effects. Some employees interpreted a managerial tool for improving effectiveness as an invitation to raise challenging points of difference rather than as something ‘beneficial for the organization’. We show that the process of introducing a culture that aims to encourage employees to speak up can produce tensions and contradictions that make various types of organizational paradoxes salient. Telling people to ‘speak up!’ may render paradoxical tensions salient and even foster a sense of low PsySafe. 相似文献

This paper studies how consumers' reported practices related to food, energy use in housing, daily mobility, and tourism are combined and structured. Social practice theories are the main theoretical framework of this research. Data are drawn from a sensitisation campaign run by the WWF-Belgium and the methods developed to attempt to translate the theoretical focus to practices. Results show that both the low number of ‘green’ practices reported and the multiplicity of combinations of practices indicate a rather important compartmentalisation of ‘green’ practices and seem to refute the hypothesis of vast domino effects in these four different areas. In addition, a wider openness to information on environmentally friendlier practices is associated with a larger number of such practices, which raises questions about the design of such campaigns. Finally, there is no conventionalised way of linking practices and commitments taken by the respondents to reduce their environmental impact. A few policy recommendations are derived for sensitisation campaigns that often assume domino effects between ‘green’ practices, and for tools dealing with personal carbon awareness. 相似文献

Stimulus generalization and contextual control affect the development of equivalence classes. Experiment 1 demonstrated primary stimulus generalization from the members of trained equivalence classes. Adults were taught to match six spoken Icelandic nouns and corresponding printed words and pictures to one another in computerized three-choice matching-to-sample tasks. Tests confirmed that six equivalence classes had formed. Without further training, plural forms of the stimuli were presented in tests for all matching performances. All participants demonstrated virtually errorless performances. In Experiment 2, classifications of the nouns used in Experiment 1 were brought under contextual control. Three nouns were feminine and three were masculine. The match-to-sample training taught participants to select a comparison of the same number as the sample (i.e., singular or plural) in the presence of contextual stimulus A regardless of noun gender. Concurrently, in the presence of contextual stimulus B, participants were taught to select a comparison of the same gender as the sample (i.e., feminine or masculine), regardless of number. Generalization was assessed using a card-sorting test. All participants eventually sorted the cards correctly into gender and number stimulus classes. When printed words used in training were replaced by their picture equivalents, participants demonstrated almost errorless performances. 相似文献

This paper gives an overview of a participatory ergonomic intervention aimed at reducing low back pain cases in the dispatch department of a catalogue and e-commerce retail company. Based on the findings of the ergonomic analysis and design committee, the company's own employees redesigned the assembly line's layout. As a result of these changes two job tasks that involved manual material handling of boxes, identified by the revised NIOSH equation as posing an increased risk for lifting-related low back pain, were totally eliminated, and the employees responsible for moving boxes from the end of the assembly line to pallets on the ground were given more control over their jobs, and these jobs were also enriched with a new, less heavy task. These results demonstrate that participatory ergonomic interventions are a viable and effective strategy to reduce the exposure to work-related physical and psychosocial risk factors for low back pain. 相似文献

Occupational cold exposure is an important risk factor that increases stress at work and can induce many health effects like diseases and symptoms related to cold, including work-related musculoskeletal disorders. The methodological procedures were performed to measure these environmental variables as recommended by the ISO 7726/85. For the analysis of repetitiveness was used the OCRA checklist and evaluation of musculoskeletal morbidity conducted by the Nordic Musculoskeletal Questionnaire. So the objective of this study was to investigate the correlation between cold environmental variables and prevalence of musculoskeletal morbidity in the repetitive work. Was found association between work in cutting and boning sector (occupational cold and repetitive work) and the presence of musculoskeletal morbidity, with a significance of 99%. 相似文献

In the workplace there are risk factors that can overwhelm the health of the worker causing physical and psychological disorders. Among these disorders, is occupational stress. Thus, this research proposes to measure the mental workload of job stress from the identification of demand, control and social support. It is an observational cross-sectional epidemiological character, performed with the Rectory office workers at the State University of West Paraná (Unioeste). Data collection was due to the application of the "Job Stress Scale" (JSS) and in its reduced version adapted to Portuguese. The survey sample consisted of 44 individuals. Statistical analysis was correlated inversely with medium intensity (r = -0.404) between age and social support. For males was found between control and age (r = 0.603). According to the data obtained, we conclude that most workers are exposed to passive work, leading to loss of skills or disinterest in the job. This study highlights the importance of research in the area and the need for new actions that change the conditions of stress at work. 相似文献

The aim of the study was to obtain anthropometric data of adult wheelchair users at Mexico. This study count with 108 disabled people (56 men and 52 women) using the wheelchair and having the upper extremities sufficiently efficient to perform professional activities. The subjects were aged 18-60. From the measurements obtained, it can be said that in each of these measures was observed that men have larger dimensions than women, except for body depth, in which women had a slightly greater difference. When comparing the data in this study against other studies it shows that there is a significant difference between the averages of these studies. Similar results were obtained when comparing our data against data of standard population. Anthropometric data obtained through this study appear to be the only of this kind in Mexico and showed significant differences between measures of disabled persons and standard persons. the use of these data may be helpful for the proper design of workstations designed for use by adults who use. 相似文献

Due to the lack of anthropometric information in northwest Mexico, we did an anthropometric study that represents the population physical characteristics and that is reliable for the design or redesign of workstations. The study was divided in two phases. The first one was the anthropometric study of 2900 automotive industry workers in northwest of Mexico. The study includes 40 body dimensions of 2345 males and 555 females personalized to be used in future researches. Second phase includes compared anthropometric characteristics of population reported in four Mexican studies and a Colombian study against the current study. Benefits of this project are: a reliable database of anthropometric characteristic of automotive industry population for workstations design or redesign that match with the users, increase product quality and reduce economic, medical and union complains. 相似文献
