Abstract. The paper deals with present, demographically-based problems in highly-developed labour markets, with special reference to the Belgian and Dutch experience. Both sluggish inflow by young cohorts and early retirement by senior workers are analysed. The first of these phenomena can be explained by the falling birth rate and increasing educational levels; the second phenomenon is the result of technological changes in the labour market and a social security system which offers attractive opportunities for early outflow. For companies, this trend translates into a loss of experience and a loss of corporate culture. On top of this, the social security system is coming under heavy pressure and scarcity symptoms are likely to develop on the supply side of the labour market. 相似文献

Post-crisis, macro-prudential ideas have challenged the epistemic authority of private risk management technologies, declaring them to be pro-cyclical contributors to systemic risk. This discursive challenge has been most critical of the shadow banking system, where private risk management instruments are central. This challenge, however, has not been translated into regulatory tools which reflect these convictions. This paper studies this process of discursive challenge to (failed) regulatory intervention for the case of the repo-market, the heart of the current shadow banking system. It traces regulatory efforts on the global and EU level from regulatory statements to (lack of) action, documenting both the persistent articulation of macro-prudential ideas challenging private risk-management systems and timid to no regulatory intervention. It links this hiatus to international coordination problems, the need for macro-prudential action to span regulatory communities, involving banking and financial market authorities and disagreements between micro- and macro-prudentially oriented regulators. The lack of evidence and the difficulty to generate it are identified as major impediments for regulatory consensus, further aggravated by ambiguities about the goals of anti-cyclical regulation. Beyond governance problems and the persistent appeal of private risk-management systems, the paper thus points to difficulties operationalizing macro-prudential ideas as a major explanatory factor. 相似文献

A simple connected graph G with 2n vertices is said to be k-extendable for an integer k with \(0<k<n\) if G contains a perfect matching and every matching of cardinality k in G is a subset of some perfect matching. Lakhal and Litzler (Inf Process Lett 65(1):11–16, 1998) discovered a polynomial algorithm that decides whether a bipartite graph is k-extendable. For general graphs, however, it has been an open problem whether there exists a polynomial algorithm. The new result presented in this paper is that the extendability problem is co-NP-complete. 相似文献

Most studies that have examined whether a child’s death influences parental relationship stability have used small-scale data sets and their results are inconclusive. A likely reason is that child loss affects not only the risk of parental separation, but also the risk of having another child. Hence parity progression and separation must be treated as two competing events in relation to child loss. The analysis in this paper used Finnish register data from 1971 to 2003, covering over 100,000 married couples whose durations of both first marriage and parenthood could be observed. We ran parity-specific Cox regressions in which process time started from the birth of each additional child. All marriages included women of childbearing age, none of whom had experienced any child death on entering the analysis. We find that child loss only modestly influences the divorce risk, whereas its effect on the risk of parity progression is considerable. 相似文献

Theory suggests that the field of study may be at least as consequential for fertility behavior as the duration and level
of education. Yet, this qualitative dimension of educational achievement has been largely neglected in demographic studies.
This article analyzes the mechanisms relating the field of study with the postponement of motherhood by European college-graduate
women aged 20–40. The second round of the European Social Survey is used to assess the impact of four features of study disciplines
that are identified as key to reproductive decision making: the expected starting wage, the steepness of the earning profile,
attitudes toward gendered family roles, and gender composition. The results indicate that the postponement of motherhood is
relatively limited among graduates from study disciplines in which stereotypical attitudes about family roles prevail and
in which a large share of the graduates are female. Both the level of the starting wage and the steepness of the earning profile
are found to be associated with greater postponement. These results are robust to controlling for the partnership situation
and the age at entry into the labor market. 相似文献

This paper takes the theory of value change as developed by Inglehart as a point of departure and tests its implications for
the determinants of human happiness. It investigates whether the importance of post-material concerns for happiness, relative
to that of materialist concerns, is indeed higher in rich post-industrial societies. Personal autonomy and job creativity
serve as indicators for post-materialist concerns, the income domain as an indicator for materialist concerns. The main assumption
is put against data for 48 countries from wave 5 of the World Values Survey, the most recent survey, which covers the full
range from poor agrarian to rich post-industrial societies. Employing a multi-level design, the paper indeed reveals a quite
consistent pattern towards post-materialist happiness as we move from poor to rich societies. This pattern seems to be driven
by both a devalorization of material concerns and a valorization of post-materialist concerns, although the evidence suggests
that the former trend is stronger and more linear than the latter. 相似文献

This article applies research on paradox, semantics, and theories of groups and logical types to public relations, particularly the concept of relationship management. Paradoxes create tension and are often produced by semantic disturbances resulting from errors in logical typing. Communication is inherently paradoxical. The article contends that progress in public relations practice and scholarship has been inhibited by a failure to recognize or reconcile paradoxes associated with popular concepts, such as relationship management, mutually beneficial relationships, and symmetrical communication. Such concepts breach levels of communication to create logical fallacies and place practitioners into a double bind of promising more than they can deliver without resorting to coercion and manipulation. The article introduces Group Theory and the Theory of Logical Types, and suggests that public relations reframe relationship management with relating management, a practices more consistent with Kant's humanity imperative. 相似文献

This study proposes theoretical and practical frameworks to systematically examine mediated public relations in social media spaces. We applied a social network conceptual framework to identify and characterize social mediators that connect the US State Department with its international public. The results showed that social mediators vary in terms of their formality and interdependence. Formal social mediators were primarily US government agencies while informal social mediators were nongovernmental organizations (NGOs) and individuals. Notably, relationships with populations in the Middle East and North Africa were mediated primarily by informal actors, and formal mediators played a key role in connecting the public with everywhere else in the world. Government-related formal mediators and informal social mediators showed similar levels of bilateral relationships. In contrast, news media, the most traditional public relations mediators, were rarely found as social mediators and demonstrated the most unilateral relationships. 相似文献
