The impact of a workplace terrorist attack on employees' perceptions of leadership: A longitudinal study from pre- to postdisaster

A terrorist attack targeting a workplace represents an organizational crisis that requires the leaders to manage emerging threats. The changing roles and expectations of the leaders are reflected in the employees' perceptions of them over time. The purpose of this study was to determine whether the 2011 Oslo bombing attack affected the targeted employees' perceptions of the leadership behaviors of their immediate superiors or the organizational managers' interest in the health and well-being of their workers. Ministerial employees (n ≈ 180) completed questionnaires on fair, empowering, and supportive leadership, in addition to human resource primacy, on two occasions several years prior to the terrorist attack. Assessments were then repeated one, two, and three years after the attack. Changes in the course of perceived leadership from predisaster to postdisaster were examined using bootstrapped t-tests and latent growth curve models. Furthermore, the general course of perceived leadership was compared with a nonexposed control sample of matched employees. Results showed that employees with high levels of posttraumatic stress perceived their immediate leader to be less supportive. However, overall perceptions of leadership were remarkably stable, which suggests that the effects of critical incidents on perceptions of leadership may be negligible.     

The t-information and its use in multivariate problems and time-series analysis

The second moment of recently introduced scalar inference function can be viewed as generalized Fisher information of the continuous probability distributions. In this paper we call it the t-information and give some possible applications of the new concept.     

Your position in society matters for how happy you are

This article shows that people's perception of their position in society is strongly correlated with their level of happiness, and thus that differences in happiness levels among countries in different welfare state clusters are influenced by people's perceptions of their relative position in society (subjective position). The study drew on data from the European Social Survey. Two important findings emerged from the analysis. First, an individual's subjective position in society is a more important predictor of happiness than objective measures such as income, education and labour market position. Second, the link between individuals’ perceived position in society and their level of happiness is moderated by the welfare state. In the Nordic countries, people's perceptions of their position in society have less influence on happiness whereas in Eastern European countries we found a strong connection between subjective position and happiness.     

Sexuality in Older Adults (65+)—An Overview of the Literature,Part 1: Sexual Function and its Difficulties

Objectives: The aim of the current article was to provide an overview of literature on sexual function and sexual difficulties in older adults. Method: The authors conducted a narrative review of papers published in English between January 2005 and July 2015 based on an extensive search in PsycINFO. Results: The review showed that although common biological changes may adversely affect sexual function in old age, sexual experience seems to also be affected by psychological and interpersonal factors. Conclusions: Greater life expectancy and better medical care will result in older individuals with chronic diseases living longer. The need for help to cope with changes in sexual health is likely to increase in older adults, as sexuality may be negatively affected through several pathways.     

Fourier–type tests involving martingale difference processes

We develop testing procedures which detect if the observed time series is a martingale difference sequence. Furthermore, tests are developed that detect change–points in the conditional expectation of the series given its past. The test statistics are formulated following the approach of Fourier–type conditional expectations first proposed by Bierens (1982 Bierens, H. J. (1982). Consistent model speci?cation tests. J. Econometr. 20:105–134.[Crossref], [Web of Science ®] , [Google Scholar]) and have the advantage of computational simplicity. The limit behavior of the test statistics is investigated under the null hypothesis as well as under alternatives. Since the asymptotic null distribution contains unknown parameters, a bootstrap procedure is proposed in order to actually perform the test. The performance of the bootstrap version of the test is compared in finite samples with other methods for the same problem. A real–data application is also included.     

Placement characteristics and stability: a longitudinal analysis of Norwegian children in foster homes

This paper investigates how enhanced support for foster parents, such as covering fees and providing consultants and relief, may reduce the number of replacements experienced by children in foster care. It also investigates the extent to which replacements are associated with family (kin) vs. non‐family foster parents, or with legal characteristics of the placement (i.e. forced administrative decisions vs. relief measures agreed upon by the parents). Statistical analyses of administrative data from Norway investigated the longitudinal relationships between these characteristics and the number of replacements at two levels – children (N = 16 109) and municipalities (N = 418) – over 5 years (2007–2011). The results reveal modest associations between enhanced support and fewer replacements; for example, replacement rates are lower for children placed in homes of kin than in non‐family homes. Replacements also tend to be fewer when the placement is forced rather than consensual.     

Profile of the Present Slovak Society and its Regional Differences

The article is the first attempt in assessment of the development and the present situation of social structure and stratification in Slovakia. Its principal aim is to develop the profile of the present society in Slovakia, which reflects the pace and complexity of the transformation process and its impact on society. Processing of Micro census data from 2003 led to creation of the profile of society in Slovakia at the national level based on income distribution but also knowledge on regional societies and differences between them were obtained. It was found out that the present profile of the society in Slovakia is pear-shaped which means strong representation of lower strata and weaker representation of higher middle and high strata. The profile disclosed some specific features and inconsistencies in the present society of Slovakia, which were, and still are determined by many non standard past and present phenomena and processes often disguised by reforms. The information drawn in regions has facilitated identification of the basic nature and structure of regional societies, some of their specific features and negative elements and to demonstrate their highly differentiated character.

How the host nation's boundary drawing affects immigrants’ belonging

Across Western democracies, the place for newcomers in the host society is debated, involving often a questioning of immigrants’ belonging to their new nation. This article argues that immigrants’ feeling of host national belonging depends on how the host nation imagines its community and its concomitant boundaries. Utilising survey and country level data in multilevel regressions, immigrants’ belonging is found to vary significantly across the 19 countries included. A central contribution is the finding that citizenship policies do not explain this cross-national variation. Instead, what matters is the informal boundary drawing produced in the majority population's conception of what is important for being part of the national ‘us'. Thus, immigrants’ belonging is significantly greater when the majority population prioritises attainable criteria of national membership. In addition, these priorities are shown to have deep historical roots as immigrants’ belonging is greater in settler countries and in nations which democratised early. By showing that national imageries have consequences for a country's welcoming capacities, and by showing that these welcoming capacities are historically path dependent, the study contributes to the debate within nationalism studies about national identity's causal significance.     

Modified minimax estimation of regression coefficients

Working with the linear regression model (1.1) and having the extraneous information (1.2) about regression coefficients the problem exists how to build estimators (1.3) with the risk (1.4) which enable to utilize the known information in order to reduce their risk as compared with the risk (1.6) of the LSE (1.5). Solution of this problem is known for the positive definite matrix T, namely in form for estimators (1.8) and (1.10).First, it is shown that the proposed estimators (2.6),(2.9) and (2.16) based on psedoinversions of the matrix L represent the solution of the problem of the positive semidefinite matrix T=L'L.Further, the problem of interpretability of estimators in the sense of the inequality (3.1) exists; it is shown that all mentioned estimators are at least partially interpretable in the sense of requirements (3.2) or (3.10).     

Fertility Decline in Czechoslovakia During the Last Two Centuries

The decline of fertility in Czechoslovakia on the territory of the Czech Socialist Republic began with a rise in the age at marriage; the decline of marital fertility began only after 1860. On the territory of the Slovak Socialist Republic marital fertility began to decline after 1900 without previous significant changes in the age at marriage. The differences between the demographic behaviour in the two parts of Czechoslovakia have persisted, although they are now gradually disappearing. There are other significant regional differences in the fertility decline caused by the overall process of economic and social development. The end of the demographic transition in the Czech Socialist Republic came during the 1930's and in the Slovak Socialist Republic during the 1960's.
