Within the so‐called normal society one can observe again and again symptoms of reluctance to being closely associated with people with physical disabilities. The general opinion is that this group of people is characterised by specific psychological and physical functioning and they are thought to have distinct needs and expectations as regards family life. To verify and confirm the above, comparative research was undertaken to find out how young able‐bodied, blind and persons using wheelchairs evaluate marriage. The subject of the research was the importance ascribed to the hierarchy of values related to marriage and family, and the types of needs satisfied through these institutions of social life. The participants were asked to evaluate such phenomena as love, sexual life and parenthood as well as expressing their attitude and opinion on conjugal infidelity. The results obtained do not indicate any significant differences in attitudes and views presented between the groups under consideration. All valued marriage and family life very highly and had similar expectations, however, not all will be able to fulfil their needs and aspirations in these areas. It will be quite complicated, especially so for those who are disabled. All possible failures are caused by, first of all, negative attitudes of the society towards erotic activities of people with disabilities.  相似文献

In December 2000, five Polish state institutions of higher education in economics established the Foundation for the Promotion and Accreditation of Economics Programmes. Its mission, as stated in its charter, is to improve the quality of economics and management education by disseminating and supporting its best models. This mission takes on particular importance on the eve of the inclusion of Polish higher education institutions into the European Higher Education Area. This article serves as a case study based on the experience of the Poznan´ University of Economics and what it gained from its accreditation in early 2003.  相似文献

The aim of this article is to demonstrate the key role of public relations in increasing the competitive advantages of higher education institutions. It identifies and describes the mechanism of the shift in interest from advertising to public relations that results from the increasing complexity of the environment of a private higher education institution. Moreover, the authors conduct an analysis of the main target groups of public relations activities, referring to the conceptual model of the “two markets” according to which a private higher education institution “sells” access to education to potential candidates and then “sells” its graduates on the labour market. The practical example of the marketing and public relations activities undertaken by the authors at the School of Banking in Poznan´ since 1994 are presented and elucidated.  相似文献

Dual-task effect on postural control in high-level competitive dancers   总被引:1,自引:0,他引:1  
We investigated balance in 33 competitive dancers (17 females, 16 males) and 22 controls (17 females, 5 males) (age 16-27 years) on a force plate in two conditions: single task (quiet stance) and dual task (with a concurrent mental task). Balance was evaluated using centre-of-pressure shift (sway) variability, mean speed, frequency, and sample entropy. The effect of the dual task in the medio-lateral plane was comparable in both groups, decreasing sway variability (P < 0.05) and increasing mean speed (P < 0.001), frequency, and sample entropy (P < 0.001), showing that the participants effectively increased the level of automaticity. In the antero-posterior plane, the dual task also increased sway frequency and sample entropy (P < 0.01) in dancers without affecting their standing performance. In contrast, postural control in non-dancers was vulnerable to reduced cognitive investment, which adversely interfered with baseline performance. There were very high correlations between sway sample entropy and frequency in each group, plane, and task (r = 0.92-0.98, P < 0.001), indicating that both parameters may measure the same characteristic of postural control and that higher sway frequency may play an important role in protecting stability in dual tasking. The postural control of dancers and non-dancers appears to be similar, although dancing seems to facilitate the increased level of automatic control in the antero-posterior plane.  相似文献

This paper proposes a benefit of the doubt (BoD) approach to assess the research performance of 37 public Australian universities based on data from 2015. The primary activities of Higher Education institutions are teaching and research, but the prestige of a university depends mainly on the results of its research activities. The BoD method is rooted in the data envelopment analysis methodology, which enables the flexible and data‐based assignment of weights to aggregated variables. Full weighting flexibility, however, allows zero weights, which can lead to unrealistic results. For this reason, the proposed model has been supplemented with additional weight restrictions. The assessment considers key performance factors: number of publications and citations; number of completed doctoral degrees; amount of research grants; and percentage of science graduates. Unlike earlier research on Australian universities, this study uses the number of publications and citations from the Web of Science database. The results provide a ranking of universities and recommendations for decision makers regarding the direction of future improvement actions for the worst‐performing universities.  相似文献

This paper argues that evolutionary thinking and modeling can contribute to the emerging research on sustainability transitions and their management. Evolutionary theory provides a range of concepts and mechanisms that are useful in making existing theorizing about transitions more precise and complete. In particular, we will discuss how the multi-level, multi-phase, co-evolutionary, and social learning dynamics underlying transitions can be addressed in evolutionary models. In addition, evolutionary theorizing offers suggestions for extending current theoretical frameworks of transitions. Group selection provides a good example. We review the small set of formal evolutionary models of sustainability transitions, and show that existing formal evolutionary models of technological, social and institutional change can provide useful inputs to transition research and management.  相似文献

In this paper, a new reaching law based sliding mode control strategy for discrete time systems is introduced. Contrary to most existing approaches, the new strategy uses a sliding variable with relative degree two. It is demonstrated that the new reaching law drives the sliding variable to a narrower quasi-sliding mode band than its relative degree one equivalent, while simultaneously ensuring the desired dynamic properties of the system. Furthermore, it is shown that the smaller quasi-sliding mode band width is reflected in reduced magnitude of all state variables in the sliding mode.  相似文献

The Multilevel Information System (MLIS), extension of typical Information Retrieval System towards more complete data processing, is discussed. MLIS integrates functions typical for data base management systems and retrieval-oriented systems. Several levels of data accessing are provided, each level developed for a different class of users. End-user level is based on simple query language, trained user level on a relational model, and application programmer level on a Data Manipulation Language nested in high level programming language. The last two levels are discussed in detail.  相似文献
