In this paper the authors examine the theoretical framework of the set of laws, provisions, regulations, recommendations and pronouncements that embody the active employment policies in Europe. They illustrate that the theoretical framework is influenced in its attribution of meaning and significance to its subject matter by its relationship with the definitions of employment. To do this they provide an analysis of: the collective agencies, the courses of action, the recipient groups, the relations between the collective agencies, the courses of action decided upon and their recipient subjects, the supporting measures by which these courses of action will be implemented.  相似文献

Worldwide modern organisation is continuously crossed by a great number of information but frequently information is not accurate, the needed information is not generated or it cannot be easily identified and, more, the information cannot flow through the whole organisation. This paper proposes the application of lean thinking in the field of information management. In the areas of manufacturing and production, the lean thinking is well known but usually the importance of a holistic approach is neglected and the improvement involves only the production and logistic areas and there is not a specific focus on the lean information management. We applied lean thinking to information management in order to improve the performance of an automotive company. We analysed the as-is company condition, we identified the present muda and we introduced the necessary changes. Then, we verified the modification efficiency through the calculation of a performance index. The paper proposes an interesting and exhaustive case of lean information management application and it highlights the possible improvement of such approach. The results of this study are not sector specific: they are not only applicable by other automotive industries, but they can also be extended to many other sectors.  相似文献

University drop-out is a topic of increasing concern in Italy as well as in other countries. In empirical analysis, university drop-out is generally measured by means of a binary variable indicating the drop-out versus retention. In this paper, we argue that the withdrawal decision is one of the possible outcomes of a set of four alternatives: retention in the same faculty, drop out, change of faculty within the same university, and change of institution. We examine individual-level data collected by the administrative offices of “Sapienza” University of Rome, which cover 117 072 students enrolling full-time for a 3-year degree in the academic years from 2001/2002 to 2006/2007. Relying on a non-parametric maximum likelihood approach in a finite mixture context, we introduce a multinomial latent effects model with endogeneity that accounts for both heterogeneity and omitted covariates. Our estimation results show that the decisions to change faculty or university have their own peculiarities, thus we suggest that caution should be used in interpreting results obtained without modeling all the relevant alternatives that students face.  相似文献

Background

Gait variability can be considered an indirect measure of gait stability, in particular regarding temporal or spatial variability assessment. Physical activity, such as walking, is advised for the elderly and can be improved by gait stability. The aim of this study was to investigate the associations between gait stability and physical activity in women of different age ranges.

Methods

Forty-two healthy women of different age ranges (18-40 yrs. and 65-75 yrs.) were recruited in the study. To assess physical activity, the subjects wore a multi-sensor activity monitor for a whole week, inferring the time spent in moderate to vigorous physical activity (MVPA). MVPA were analysed in bouts of at least 10 subsequent minutes (MVPAbouts) and in overall minutes (MVPAtot). A kinematic analysis was performed with an optoelectronic system to calculate gait variability - expressed as standard deviation (SD) and coefficient of variability (CV) of step width, stride length, stance and swing time (during treadmill walking at different speeds).

Results

Elderly women, with high walking speed (5 km/h), and moderate step width variability (CV = 8–27%), met the recommended levels of physical activity (MVPAtot and MVPAbouts). Furthermore, gait variability, adjusted for age and number of falls, was significantly and negatively associated with MVPAtot only at 3.5 km/h, and with MVPAbouts only at 4 km/h.

Conclusions

In a population of healthy elderly women, gait variability was significantly and negatively associated with the level of physical activity. Healthy elderly women, with moderate gait variability (step width variability), and high preferred walking speed, seem to be able to meet the recommended levels of physical activity.

For human factors (HF) to avoid being considered of "side-car" status, it needs to be positioned within the organization in such a way that it affects business strategies and their implementation. Tools are needed to support this effort. This paper explores the feasibility of applying a technique from operational research called cognitive mapping to link HF to corporate strategy. Using a single case study, a cognitive map is drawn to reveal the complex relationships between human factors and achieving an organization's strategic goals. Analysis of the map for central concepts and reinforcing loops enhances understanding that can lead to discrete initiatives to facilitate integration of HF. It is recommended that this technique be used with senior managers to understand the organizations` strategic goals and enhance understanding of the potential for HF to contribute to the strategic goals.  相似文献

This paper explores key Internet search trends for electoral information vis-à-vis the broader media ecology in the UK and the US. An innovative methodology is introduced that maps the informational trajectories of key election events by combining Google Trends data linked to significant news events during the campaigns. While the research found spikes of search that suggested a seemingly trivial event in the US could drive voters to search out deeper information on related policy issues, the study did not find the same phenomenon in the UK. This invites a reflection on the opportunities available to Internet users/voters in the changing informational landscape and how scholars can leverage Google Trends records to better understand how voters seek information in new and evolving media ecologies.  相似文献

Development aid is commonly advocated as one of the most effective instruments to reduce international migration. Nevertheless, empirical evidence shows that push factors do not automatically result in massive migrations and that aid policies systematically fail to meet their stated objectives. Recently, several contributions have argued that an increase in sending countries’ wealth may lead to a rise in migration, rather than to a reduction, because it enables people to assume the costs and risks of migrating. However, despite the growing number of studies on this phenomenon, the role played by Official Development Assistance (ODA) has not received attention yet. This paper aims at providing empirical evidence on this specific issue. In particular, we investigate the relation between ODA and international migration rates of sub‐Saharan countries. We argue that ODA may have a positive effect on migration decisions for two reasons. First, ODA improves workers’ ability to cover the costs of migration, by providing new job opportunities and in turn increasing incomes in the recipient country. Second, ODA, which is often associated with development programs in education, communication services, and business opportunities, may also stimulate mobility aspirations of potential migrants. We develop an econometric analysis in order to investigate this hypothesis. Specifically, we perform a three‐stage least square estimation on a sample of 48 sub‐Saharan countries. We build a two‐equation model, so as to allow for endogeneity of ODA, and find that ODA has a positive and statistically significant effect on migration outflows. Thus, as our main contribution, we argue that development aids are not substitute for migration and that the traditional aid policies (such as those of the European Union), aimed at curbing migration by providing international financial aids, might need to be reconsidered.  相似文献

The question of how to achieve greater levels of sustainable development is intrinsically linked with the discussion concerning new forms of governance. Structural funds have become most influential in promoting sustainable development and appropriate forms of governance across the EU. They have been very important in introducing new innovative forms of co‐ordination in many countries and have encouraged the mobilization of new political actors. Structural Funds can be considered as a most interesting laboratory for the development of new governance patterns, which are urgently needed for coping with accelerated change and increasing complexity. Multi‐level governance in the spirit of subsidiarity will not be possible without flexible objective‐oriented management approaches instead of the rigid attribution of competences. This requires new conceptual approaches, procedures, and instruments. ‘SQM—Sustainable Quality Management®’ is a coherent system for the conception, support, monitoring and evaluation of sustainable development processes. A series of pilot projects in the last five years have shown its potential and utility. The SQM system includes concepts, methods and operational tools that have proved to be applicable and comprehensible in different European cultures. Internet‐based SQM software tools support every step in the policy cycle. Sustainable development is conceived as an overarching principle that governs the management of processes and covers all policy principles postulated by the EU. In the use of a common framework over the whole policy cycle and the coherent implementation of basic principles there is the promise of achieving better orientation towards sustainable development and considerable efficiency gains.  相似文献
