In this article we discuss the emergence of ‘youth unemployment regimes’ in Europe, that is, a set of coherent measures and policies aimed at providing state responses to the problem of unemployment and, more specifically, youth unemployment. We classify these measures and policies along two main dimensions: unemployment regulations and labour market regulations. Using original data, we show how seven European countries locate on these two dimensions as well as within the conceptual space resulting from the combination of the two dimensions. Our findings show cross‐national variations that do not fit the traditional typologies of comparative welfare studies. At the same time, however, the findings allow for reflecting upon possible patterns of convergence across European countries. In particular, we show some important similarities in terms of flexible labour market regulations. In this regard, the recent years have witnessed a trend towards a flexibilisation of the labour market, regardless of the prevailing welfare regime. 相似文献

This paper combines Alfred Shultz and Herbert Simon's theories of action in order to understand the grey area between dynamic and completely unstructured decision making better. As a result I have put together a specific scheme of how choice elements are represented from an agent's personal experience, so as to create a bridge between the phenomenological and cognitive‐procedural approaches of decision making. I first look at the key points of their original models relating Alfred Schutz's “provinces of meaning” and Herbert Simon's “satisficing” mechanism. I then consider the particular concept of intentionality and reasoning by analogy for different choice settings. Finally I have suggested a perspective based on creative behaviour and sense‐making for ill‐structured conditions. 相似文献

Family structure and children's achievements 总被引:2,自引:2,他引:0
In this paper we estimate the relationships between several outcomes in early adulthood (educational attainment, economic inactivity, early childbearing, distress and smoking) and experience of life in a single-parent family during childhood. The analysis is performed using a special sample of young adults, who are selected from the first five waves of the British Household Panel Survey (1991–95) and can be matched with at least one sibling over the same period. We also perform level (logit) estimation using another sample of young adults from the BHPS. We find that: (i) experience of life in a single-parent family is usually associated with disadvantageous outcomes for young adults; (ii) most of the unfavourable outcomes are linked to an early family disruption, when the child was aged 0–5; and (iii) level estimates, whose causal interpretation relies on stronger assumptions, confirm the previous results and show that, for most outcomes, the adverse family structure effect persists even after controlling for the economic conditions of the family of origin.

Erectile dysfunction is a common disease characterized by endothelial dysfunction. The aetiology of ED is often multifactorial but evidence is being accumulated in favor of the proper function of the vascular endothelium that is essential to achieving and maintaining penile erection. Uric acid itself causes endothelial dysfunction via decreased nitric oxide production. This study aims to evaluate the serum uric acid (SUA) levels in 180 ED patients, diagnosed with the International Index of Erectile Function-5 (IIEF-5) and 30 non-ED control. Serum uric acid was analyzed with a commercially available kit using ModularEVO (Roche, Monza, Italy). Within-assay and between-assay variations were 3.0% and 6.0%, respectively. Out of the ED patients, 85 were classified as arteriogenic (A-ED) and 95 as non-arteriogenic (NA-ED) with penile-echo-color-Doppler. Uric acid levels (median and range in mg/dL) in A-ED patients (5.8, 4.3–7.5) were significantly higher (p?.001) than in NA-ED patients (4.4, 2.6–5.9) and in control group (4.6, 3.1–7.2). There was a significant difference (p?.001) between uric acid levels in patients with mild A-ED (IIEF-5 16–20) and severe/complete A-ED (IIEF-5?≤?10) that were 5.4 (range 4.3–6.5) mg/dL and 6.8 (range 6.4–7.2) mg/dL, respectively. There was no difference between the levels of uric acid in patients with different degree of NA-ED. Our findings reveal that SUA is a marker of ED but only of ED of arteriogenic aetiology. 相似文献

The study investigated the relationship between patterns of attachment and emotional competence at the beginning of middle childhood in a sample of 122 seven‐year‐olds. A new battery of tasks was developed in order to assess two facets of emotional competence (emotion recognition and knowledge of regulation strategies). Attachment was related to the choice of emotion regulation strategies in hypothetical situations; secure children produced the highest frequency of cognitive engagement strategies (e.g., reappraisal), and disorganized children the lowest. Insecure children produced more behavioral engagement strategies and fewer behavioral diversion ones. There was a minor effect of attachment on emotion recognition, with disorganized children scoring lower in the discrimination of facial expression. Consistent sex differences were also apparent in the direction of a female advantage in emotional competence: Girls scored higher in emotion recognition than boys, and in the regulation knowledge task, they produced fewer helpless answers and more cognitive engagement strategies. 相似文献

Trust has been shown as a crucial factor for the adoption of new technologies. Surprisingly, trust literature offers very little guidance for systematically integrating the vast amount of behavioral trust results into the development of computing systems. The aim of this article is to develop a method for deriving trust supporting components for ubiquitous computing systems. The method is used to derive four trust supporting components for a ubiquitous restaurant recommendation system. Afterwards, the system is evaluated using a laboratory experiment with 166 undergraduate students. The results show that the users’ trust as well as their intention to use the system could be significantly increased. To the best of our knowledge, this is the first article developing and evaluating a method for systematically integrating the behavioral trust results into the development of a computing system and its value. 相似文献

In this note, we propose some comments and some extensions of the inoperability input-output model (IIOM), as recently proposed by Santos and Haimes (2004). In particular, we propose the use of some analytic tools capable of providing information on the reaction of sectors subsequent to a terrorist attack on infrastructure service sectors. These tools, namely, the field of influence and the multiplier product matrix, provide information on the way sectors react to a shock on the aggregate demand and/or to a (temporary or permanent) change of production function coefficients. Finally, using the 2003 65 sectors input-output matrix for the U.S. economy, a simple empirical example is presented. 相似文献

The origin of gambling disorders is uncertain; however, research has shown a tendency to focus on specific types of games as a potential important risk factor. The principal aim of this study is to examine the relationships between types of gambling practices and gambling disorder. The data were extracted from IPSAD-Italia® 2010–2011 (Italian Population Survey on Alcohol and other Drugs), a survey among the Italian general population which collects socio-cultural information, information about the use of drugs, legal substances and gambling habits. In order to identify the “problem gambler” we used the Problem Gambling Severity Index. Three groups are considered in this analysis: no-risk gamblers, low-risk gamblers, moderate-risk/problem gamblers. Type of gambling practice was considered among two types of gambler: one-game players and multi-games players. 1.9 % of multi-game players were considered problem gamblers, only 0.6 % of one-game players were problem gamblers (p < 0.001). The percentage of players who were low and moderate-risk gamblers was approximately double among multi-game players, with 14.4 % low-risk and 5.8 % moderate-risk; compared with 7.7 % low-risk and 2.5 % moderate risk among one-game players. Results of ordinal logistic regression analysis confirmed that higher level of gambling severity was associated with multi-game players (OR = 2.23, p < 0.0001). Video-poker/slot-machines show the highest association with gambling severity among both one-game players and multi-game players, with scores of OR equal to 4.3 and 4.5 respectively. These findings suggest a popular perception of risk associated with this type of gambling for the development of gambling problems. 相似文献
