In 2004 a new working time law for physicians in hospitals was introduced, which has up until now been rarely researched in theory and is implemented in practice partially in form of new working time models, partially by relying on allowed variation rules within the law. Meanwhile, there are new discussions about changes of working time directives on the European level. This article aims to analyze the desired effects of the new working time law to decrease the workload, improve the possibilities of patient care and increase the working time satisfaction of physicians. To this end, a primary data collection is conducted in 15 hospitals and 35 hospital departments, generating 261 questionnaires, in order to empirically assess the theoretical model with the constructs working time model, workload, working time satisfaction, and possibilities of patient care using regression analyses. It can be shown that the new working time models decrease workload and enhance working time satisfaction of hospital physicians, but have no significant influence on the possibilities of patient care. These results are consistent for different ownerships and sizes of hospitals as well as for most services. No significant differences in the answers between various physician groups exist either. 相似文献

The goal of this study is to give a comprehensive empirical account of push and pull factors, situated at various societal levels, which may influence people's early retirement. Factors in two contrasting European countries have been analysed and compared: Denmark, where the rate of early exit/retirement is relatively low, and The Netherlands, where this rate is relatively high. Our analysis, looking into possible explanations for the difference in rates, includes factors that operate at the macro or institutional level of the labour market and the social security system, at the meso level of firms and companies, and at the micro level of individual workers. In addition, we not only look into the effects of structural, objective factors, which impacts are usually analysed from an incentive perspective, but also into the effects of cultural factors, i.e. of preferences, attitudes and values. Cultural factors related to early exit have not been the object of much international comparison thus far, although their possible significance is readily acknowledged. The differences in retirement behaviour in Denmark and The Netherlands are explained by the fact that Danish workers, at all three levels, are less experiencing structural and cultural factors pushing them out of the labour market, as well as experiencing factors pulling them into retirement, compared to workers in The Netherlands. 相似文献

Little information exists on the specific reflective processes that precede therapists' choice of including or not including a structured feedback procedure in their established practice. In the present study, we aim to describe and explore experienced couple and family therapists' expectations for how the comprehensive therapy feedback procedure Systemic Therapy Inventory of Change might influence their practices. Through a thematic analysis of six focus group interviews, two main themes were elicited. The first main theme involved values embedded in current practice, with the following subthemes: (1) balance between the therapist's expert knowledge and the client's experience‐based knowledge; and (2) making time to build alliances. The second main theme concerned the presumed influence on current practice, with the following subthemes: (1) ‘Systemic Therapy Inventory of Change will disturb the therapist's capacity to stay present’; (2) ‘Systemic Therapy Inventory of Change will shape conversations’; and (3) ‘Systemic Therapy Inventory of Change will contribute to increased qualitative depth’. We discuss these results in relation to the notion of Systemic Therapy Invention of Change as a ‘third party in the room’. We also discuss the results in relation to implications for collaborative practices, and for client and therapist autonomy. 相似文献

The diamond market has recently experienced important structural changes moving from a monopolistic market to a more liberalised and competitive one. As a result, diamonds are being discussed as a new investment asset class, with possible valuable portfolio contributions. The aim of this paper is to analyse their potential role within an investment framework, using previously unpublished data. We use the GemShares and NASDAQ OMX patented license and Polished Prices proprietary Price Reporting Agency (PRA) database to build our own standardized financial polished diamond basket indices (DBIs), using actual reported data of traded prices, adjusted for liquidity by traded volume. The impact of adjusting for traded volume of investment grade (only) diamonds is sufficient to develop a unique subset different to that captured and reported by the PRA. We first construct an index for High-Quality (HQ) and a second one for Medium-Quality (MQ) diamonds so we can study both of their dynamics and investment features. We further analyse the relationship the two indices have with major macroeconomic and financial variables, as well as other precious commodities to investigate their role as safe haven or hedge. We find that the DBIHQ Index returns are, on average, positively correlated with major macroeconomic variables—in particular with the Euro and Chinese Interest rates. The DBIMQ Index returns are largely uncorrelated with the same macroeconomic variables—with the exception of Euro Interest rates and the Israeli Exchange rate. When we compare our Diamond Indices returns with major financial variables and other precious commodities, we find a broad lack of correlation between their returns, and significant difference between the DBIHQ and DBIMQ Indices. We may conclude that diamonds are broadly a poor hedge for any of the portfolios we considered, with a few important exceptions—especially gold. Using Bauer and Lucey’s (Financ Rev 45(2):217–229. doi: 10.2139/ssrn.952289, 2010) approach we further tested the “safe haven value” and “hedging usefulness” of the two Indices. In contrast with previous studies we believe the unique data we accessed allowed us to demonstrate that diamonds represent a strong hedge for gold investors, and in addition exhibit features of a safe haven for stock markets during periods of financial stress. 相似文献

In this study, we investigate whether mobile device use in surveys can be predicted. We aim to identify possible motives for device use and build a model by drawing on theory from technology acceptance research and survey research. We then test this model with a Structural Equation Modeling approach using data of seven waves of the GESIS panel. We test whether our theoretical model fits the data by focusing on measures of fit, and by studying the standardized effects of the model. Results reveal that intention to use a particular device can predict actual use quite well. Ease of smartphone use is the most meaningful variable: if people use a smartphone for specific tasks, their intention to use a smartphone for survey completion is also more likely. In conclusion, investing in ease of use of mobile survey completion could encourage respondents to use mobile devices. This can foremost be established by building well-designed surveys for mobile devices. 相似文献

In this paper we argue that the new availability of digital data sets allows one to revisit Gabriel Tarde's (1843–1904) social theory that entirely dispensed with using notions such as individual or society. Our argument is that when it was impossible, cumbersome or simply slow to assemble and to navigate through the masses of information on particular items, it made sense to treat data about social connections by defining two levels: one for the element, the other for the aggregates. But once we have the experience of following individuals through their connections (which is often the case with profiles) it might be more rewarding to begin navigating datasets without making the distinction between the level of individual component and that of aggregated structure. It becomes possible to give some credibility to Tarde's strange notion of ‘monads’. We claim that it is just this sort of navigational practice that is now made possible by digitally available databases and that such a practice could modify social theory if we could visualize this new type of exploration in a coherent way. 相似文献

This article aims to study the importance of the attributes of usability and attractiveness for the semi-public spaces of Shopping Centers considering the elderly users, the psycho-cognitive and bio-physiological changes resulting from the aging process, as well as their expectations of the built space. Through a qualitative study of theoretical review with a multidisciplinary focus in architecture, ergonomics, gerontology, environmental psychology and management, the conditions of the elderly users were identified, and also the attributes related to usability and attractiveness, collected in order to understand and organize their interrelationships, to suggest recommendations about the drafting of Shopping Centers, aiming to generate projects and environments that should promote the efficient and satisfactory use for elderly and may also create a competitive advantage for these enterprises. 相似文献

With the advent of technology, the computer became a working tool increasingly present in companies. Its purpose is to increase production and reduce the inherent errors in manual production. The aim of this study was to analyze the usability of 2D graphics software in creating clothing designs by a professional during his work. The movements of the mouse, keyboard and graphical tools were monitored in real time by software Camtasia 7? installed on the user's computer. To register the use of mouse and keyboard we used auxiliary software called MouseMeter?, which quantifies the number of times they pressed the right, middle and left mouse's buttons, the keyboard and also the distance traveled in meters by the cursor on the screen. Data was collected in periods of 15 minutes, 1 hour and 8 hours, consecutively. The results showed that the job is considered repetitive and high demands physical efforts, which can lead to the appearance of repetitive strain injuries. Thus, the goal of minimizing operator efforts and thereby enhance the usability of the examined tool, becomes imperative to replace the mouse by a device called tablet, which also offers an electronic pen and a drawing platform for design development. 相似文献
