The Crowding-out Effect of Homeownership on Fertility

Mulder (Demogr Res 15:401–412, 2006) argues that homeownership has influences on a household’s fertility decision; however, literatures have concluded different findings regarding whether homeownership promotes or delays a family’s reproduction behavior. In this study, we construct the regional-based panel data comprising 23 counties and cities from 1994 to 2007 in Taiwan to investigate how and to what extent homeownership will affect fertility. Our empirical results show that the private homeownership rate is negatively related to the birthrate in Taiwan. It indicates that, under limited budget resources available in each household, the homeownership and reproduction decisions seem to compete and crowd out each other; however, from the results of the lagged models, the crowding-out effect diminishes as time goes by.     

Effect of regulatory modes on work performance: the moderating role of job familiarity and job complexity / El efecto del modo de regulación en el rendimiento laboral: el rol moderador de la familiaridad con el trabajo y la complejidad de la tarea

Prior research has shown that the combination of assessment and locomotion regulatory modes leads to the best performance-related outcomes. The aim of the current study was to analyse how familiarity and complexity moderate this relationship between the two regulatory modes and job performance. Participants’ locomotion and assessment tendencies were measured, and they were asked to rate the familiarity and complexity of their daily work tasks, as well as their job performance over the last year. Results showed that when job tasks were unfamiliar and more complex, high locomotion and high assessment were both needed for optimal performance. However, when both familiarity and job complexity were low, high locomotion alone led to the best performance. A similar result was obtained when task familiarity was high: regardless of task complexity, the best performance was shown by employees high in locomotion, no matter the assessment. In conclusion, the present study furnishes useful suggestions for employers who wish to maximize employees’ performance.     

Tablet assessment of word comprehension reveals coarse word representations in 18–⁠20-month-old toddlers

The present study explores the viability of using tablets in assessing early word comprehension by means of a two-alternative forced-choice task. Forty-nine 18–20-month-old Norwegian toddlers performed a touch-based word recognition task, in which they were prompted to identify the labeled target out of two displayed items on a touchscreen tablet. In each trial, the distractor item was either semantically related (e.g., dog–cat) or unrelated (e.g., dog–airplane) to the target. Our results show that toddlers as young as 18 months can engage meaningfully with a tablet-based assessment, with minimal verbal instruction and child–administrator interaction. Toddlers performed better in the semantically unrelated condition than in the related condition, suggesting that their word representations are still semantically coarse at this age. Furthermore, parental reports of comprehension, using the Norwegian version of the MacArthur–Bates Communicative Development Inventories, predicted toddlers’ performance, with parent–child agreement stronger in the semantically unrelated condition, indicating that parents declare a word to be known by their child if it is understood at a coarse representational level. This study provides among the earliest evidence that remote data collection in 18-20 month-old toddlers is viable, as comparable results were observed from both in-laboratory and online administration of the touchscreen recognition task.     

Histogram estimation of radon-nikodym derivatives for strong mixing data

Nonparametric inference for point processes is discussed by way of histograms, which provide a nice tool for the analysis of on-line data. The construction of histograms depends on a sequence of partitions, which we take tc be nonenibedded to allow partitions with sets of equal measure. This presents some theoretical problems, which are addressed with an assumption on the decomposition of second order moments. In another direction, we drop the usual independence assumption on the sample, replacing it by a strong mixing assumption. Under this setting, we study the convergence of the histogram in probability, which depends on approximation conditions between the distributions of random pairs and the product of their marginal distributions, and^almost completely, which is based on the decomposition of the second order moments. This last convergence is stated on two versions according to the assumption of Laplace transforms or the Cramer moment conditions. These are somewhat stronger, but enable us to recover the usual condition on the decrease rate of sets on each partition. In the final section we prove that the finite dimensional distributions converge in distribution to a Gaussian centered vector with a specified covariance.     

Strategien des Konfliktmanagements

Strategies of conflict management. Coaching, supervision and organisational development in comparisonHow do different kinds of professional consultants engage in conflict management and what do they concentrate on most in their consulting work? This article explores and compares the approaches of professional coaches, supervisors and organisational consultants, focussing on the central differences and commonalities of the consulting approaches that emerge from three case studies of conflict resolution. Whereas coaching, relying on the idea that conflicts in a business are best addressed by leaders and a top-down strategy, trains executives in conflict resolution, supervision and organisational consulting emphasize a participatory model that involves all the affected parties in conflict resolution. The author considers the various consequences these approaches have for those seeking help, as well as the substantive and methodological differences become evident in the course of consulting sessions.     

Wie Organisationsmediation mit Macht in Konflikten umgehen kann

The author distinguishes different forms of influence from power and is describing analytical models to be used for diagnosis and for conflict resolution interventions in meso-social systems like corporate organizations, NGOs, public administration, hospitals, schools, associations etc. The given models are useful for external consultants or mediators who are aiming at changing power aspects. During a process of escalation various forms of influence and power are applied which require specific approaches for interventions.     

The effect of tapering on the semiparametric estimators for nonstationary long memory processes

In this paper, we study, by a Monte Carlo simulation, the effect of the order p of “Zhurbenko-Kolmogorov” taper on the asymptotic properties of semiparametric estimators. We show that p  =  [d + 1/2] + 1 gives the smallest variances and mean squared errors. These properties depend also on the truncation parameter m. Moreover, we study the impact of the short-memory components on the bias and variances of these estimators. We finally carry out an empirical application by using four monthly seasonally adjusted logarithm Consumer Price Index series.
