We consider Web services defined by orchestrations in the Orc language and two natural quality of services measures, the number of outputs and a discrete version of the first response time. We analyse first those subfamilies of finite orchestrations in which the measures are well defined and consider their evaluation in both reliable and probabilistic unreliable environments. On those subfamilies in which the QoS measures are well defined, we consider a set of natural related problems and analyse its computational complexity. In general our results show a clear picture of the difficulty of computing the proposed QoS measures with respect to the expressiveness of the subfamilies of Orc. Only in few cases the problems are solvable in polynomial time pointing out the computational difficulty of evaluating QoS measures even in simplified models. 相似文献

Using data from the Fragile Families and Child Well being Study (N= 2,656), we examined the association between intergenerational relationships and parents' union stability five years after a baby's birth. Results showed that more amiable relationships between parents and each partner's parents, and more time children spent with paternal grandparents, were associated with increased odds that parents were co-residing by the time their focal child was age five. More time that children spent with maternal grandparents reduced union stability, although this result was not robust to methods that better address selection. These findings underscore the importance of the broader social contexts affecting couple stability. Findings further suggest that even amidst changing demographic conditions, intergenerational family ties are important for couples-and by extension-their children. 相似文献

This article argues that key values of child protection work are not the appropriate point of departure for contemplating the welfare of children in professional care. Central values, such as ‘comfort’, ‘recognition’ or ‘appreciation’ say very little about the social practices of residential care. Using data from an ethnographic study in Denmark, the article demonstrates that ideas about the needs of troubled children are realised in dissimilar ways, creating highly different living environments for institutionalised children. The principles behind these construction processes are explored, and the profound ambiguity of values in childcare is discussed as an effect of residential care’s being an ‘institutional’ or ‘human service’ type of organisation. 相似文献

The purpose of this study was to evaluate whether a 12-wk functional circuit-training program (FCT) could alter markers of physical frailty in a group of frail community-dwelling adults. Fifty-one individuals (31 women, 20 men), mean age (± SD) 84 (± 2.9) yr, met frailty criteria and were randomly assigned into groups (FCT = 26, control group [CG] = 25). FCT underwent a 12-wk exercise program. CG met once a week for health education meetings. Measures of physical frailty, function, strength, balance, and gait speed were assessed at Weeks 0, 12, and 36. Physical-frailty measures in FCT showed significant (p < .05) improvements relative to those in CG (Barthel Index at Weeks 0 and 36: 73.41 (± 2.35) and 77.0 (± 2.38) for the FCT and 70.79 (± 2.53) and 66.73 (± 2.73) for the CG. These data indicate that an FCT program is effective in improving measures of function and reducing physical frailty among frail older adults. 相似文献

In this paper we introduce a new tool, the mobile phone, for use in diary research. We demonstrate, with reference to two family studies conducted in Finland, how daily family dynamics can be captured by using the mobile diary. In both studies family members sent text messages (SMSs) in answer to structured diary questions three times a day over a one-week period. The participants kept also paper-and-pencil diaries. Two mobile diary items measuring mood (stressfulness and feelings of competence) both at home and at work are reported here as examples. For both items we found statistically significant daily and weekly variation as well as individual fluctuation. The data gathered by the mobile diary were congruent but not identical with the data gathered by the paper-and-pencil diary. The mobile phone method of data collection facilitated participants’ answers at the agreed times and the participants reported that answering was easy and did not take too much time. The main limitation is the lack of space for answers; therefore, the few questions that are used have to be reliable and valid. 相似文献

The cultural diversity now evident in Greek society creates educational challenges and opportunities. Space to address these is provided by the multicultural awareness aspects of the discourse of the Cross‐Thematic Curriculum Framework (CTCF). For English language classes, multicultural direction is provided through the disciplinary discussion of new teaching paradigm possibilities. In particular, these discussions encourage us to explore the repositioning of English teaching in Greek state schooling from a foreign language orientation towards a multicultural one. In this article, having set the context, we present the Multicultural Awareness Through English (MATE) paradigm. We conclude by illustrating the MATE paradigm in action.

The aim of this article is to analyse the role of the legal representative in therapeutic law, specifically in Swedish administrative court hearings relating to compulsory care. Data are collected from three types of cases where a health or social welfare authority argues that it is necessary to apply coercion to a citizen: the Care of Young Persons (Special Provisions) Act, the Care of Alcohol and Drug Abusers (Special Provisions) Act and the Compulsory Psychiatric Care Act. The data consist of audio-recordings from 39 hearings, supplemented by 28 interviews with participants in these hearings, and court documents. Three primary roles of the legal representatives are identified: defender, spokesperson and therapist. We show how the primary role of the attorney becomes that of the spokesperson, but also that the role of the therapist takes precedence over that of the defender. 相似文献
