Job quality,industrial relations and the crisis in Europe

This paper reports results from recent Eurofound research on the impact of the crisis on industrial relations and working conditions in Europe, based on the output of Eurofound's European Working Conditions Observatory and European Industrial Relations Observatory and data from the European Working Conditions Survey. Overall, the crisis – even if it is sometimes difficult to separate the effect of the crisis from megatrends in working conditions and industrial relations – seems to have had an impact on both domains. With reference to industrial relations, the impact of the crisis has influenced actors, processes, and outcomes. Regarding working conditions, the results appear to be in line with the literature on the topic, which relates the crisis to an increase in job insecurity, a decrease in work intensity, in working hours, and in anti-social working time arrangements, and a general improvement in terms of health risks and related outcomes.     

Flexible pair-copula estimation in D-vines using bivariate penalized splines

The paper presents a new method for flexible fitting of D-vines. Pair-copulas are estimated semi-parametrically using penalized Bernstein polynomials or constant and linear B-splines, respectively, as spline bases in each knot of the D-vine throughout each level. A penalty induce smoothness of the fit while the high dimensional spline basis guarantees flexibility. To ensure uniform univariate margins of each pair-copula, linear constraints are placed on the spline coefficients and quadratic programming is used to fit the model. The amount of penalizations for each pair-copula is driven by a penalty parameter which is selected in a numerically efficient way. Simulations and practical examples accompany the presentation.     

‘How to be a Happy Homosexual?!’ Non‐monogamy and Governmentality in Relationship Manuals for Gay Men in the 1980s and 1990s

This article explores discourses on non‐monogamy in relationship manuals published in the 1980s and 1990s for gay men from a perspective of governmentality. A distinctive feature of relationship manuals for gay men is the presentation of (non‐) monogamy as a matter of choice and negotiation. However, within this paradigm, most manuals problematise recreational, casual, or non‐relational sex or relationships with multiple partners through a set of discourses around the concepts intimacy, maturity, addiction and compulsion. The normative ideal of a successful gay male partnership is fleshed out in the provision of narrative schemata based on stage model theories which naturalise white middle class relationship experiences and concerns. Governmental rationality thereby enfolds itself in an interplay of several strategies including psychologisation, individualisation, normalisation, problematisation, and responsibilisation.     

Bewertung intertemporaler Abh?ngigkeiten zwischen IT-Projekten

Companies often decide in favour of IT investments (especially IT infrastructure investments) only because these investments build the foundation for more lucrative follow-up investments. Those intertemporal interdependencies among IT projects have to be considered within the scope of a value-based IT portfolio management. Therefore, current literature suggests the use of real options analysis??and therefore the application of option pricing models such as the binomial model or the Black-Scholes model. Both models require a complete market. However, because IT projects are characterized by project specific risks, which cannot be duplicated on a capital market, the forthright application of these models is problematic. This issue has been addressed within the scope of the discrete binomial model so far. In this paper we transfer these findings to the Black-Scholes model. Furthermore, we apply this approach to a real case and illustrate how a correct consideration of project specific risks using the Black-Scholes model can affect investment decisions.     

Cross-country determinants of life satisfaction: exploring different determinants across groups in society

This paper explores a wide range of cross-country determinants of life satisfaction exploiting a database of 90,000 observations in 70 countries. We distinguish four groups of aggregate variables as potential determinants of satisfaction: political, economic, institutional, and human development and culture. We use ordered probit to investigate the importance of these variables on individual life satisfaction and test the robustness of our results with Extreme Bounds Analysis. The results show that only a small number of factors, such as openness, business climate, postcommunism, the number of chambers in parliament, Christian majority, and infant mortality, robustly influence life satisfaction across countries while the importance of many variables suggested in the previous literature is not confirmed. This remains largely true when the analysis splits national populations according to gender, income, and political orientation also.

加拿大采矿业注重培养技术工人

采矿业面临着内外因素困扰,前进路上步履艰难,外部矿产品价格低迷,内部作业条件与环境恶劣.在这种严峻的情况下,矿业要千方百计克服矿产品开采与加工中的各种困难(挖掘深度加大、矿种品位降低、环保要求严格等等),除了提高生产效率、降低成本,最重要的是加快人才培养,改善人力资源管理.要达到上述目的,依靠传统办法,无法实现.所幸的是,进入21世纪后,以微电子技术为核心的科技进步为此提供了可靠的技术保证.这种需要与可能相结合就会诱导出一场变革,即技术革新,其中矿山自动化是这场变革中的主角.     

Tests of serial independence based on Kendall's process

The authors propose new rank statistics for testing the white noise hypothesis in a time series. These statistics are Cramér‐von Mises and Kolmogorov‐Smirnov functionals of an empirical distribution function whose mean is related to a serial version of Kendall's tau through a linear transform. The authors determine the asymptotic behaviour of the underlying serial process and the large‐sample distribution of the proposed statistics under the null hypothesis of white noise. They also present simulation results showing the power of their tests.
