Followership,deity and leadership

Two questions are addressed in this article: 1. Why are people attracted to leaders? 2. How are leaders' images construed? The first question is analyzed by using the concept of “deity” as a frame of reference for an “ideal model” of leadership. God as a “screen of projections” can satisfy the believer's fundamental needs and desires, as well as serving as a reference for causal attributions and a provider of transcendental meaning. Using Construal Level Theory (CLT) (Libermann & Trope, 1998), deity, as a frame of reference, also facilitates analysis of the second question. This analysis explains universal principles underlying the leadership construal, and the psychological principles and culture‐bound processes relevant to construing different images of leadership in different collectives.     

Simulation-Based Confidence Intervals for Functions With Complicated Derivatives

In many scientific problems, the quantity of interest is a function of parameters that index the model, and confidence intervals are constructed by applying the delta method. However, when the function of interest has complicated derivatives, this standard approach is unattractive and alternative algorithms are required. This article discusses a simple simulation-based algorithm for estimating the variance of a transformation, and demonstrates its simplicity and accuracy by applying it to several statistical problems.     

A relaxed approach to combinatorial problems in robustness and diagnostics

A range of procedures in both robustness and diagnostics require optimisation of a target functional over all subsamples of given size. Whereas such combinatorial problems are extremely difficult to solve exactly, something less than the global optimum can be ‘good enough’ for many practical purposes, as shown by example. Again, a relaxation strategy embeds these discrete, high-dimensional problems in continuous, low-dimensional ones. Overall, nonlinear optimisation methods can be exploited to provide a single, reasonably fast algorithm to handle a wide variety of problems of this kind, thereby providing a certain unity. Four running examples illustrate the approach. On the robustness side, algorithmic approximations to minimum covariance determinant (MCD) and least trimmed squares (LTS) estimation. And, on the diagnostic side, detection of multiple multivariate outliers and global diagnostic use of the likelihood displacement function. This last is developed here as a global complement to Cook’s (in J. R. Stat. Soc. 48:133–169, 1986) local analysis. Appropriate convergence of each branch of the algorithm is guaranteed for any target functional whose relaxed form is—in a natural generalisation of concavity, introduced here—‘gravitational’. Again, its descent strategy can downweight to zero contaminating cases in the starting position. A simulation study shows that, although not optimised for the LTS problem, our general algorithm holds its own with algorithms that are so optimised. An adapted algorithm relaxes the gravitational condition itself.     

The hidden curriculum of youth care interventions—A case study

Themes such as “effectiveness” and “evidence-based practice” currently dominate debates about the professional care of children and youth. Notwithstanding the importance of these themes, this rather narrow focus may leave the values and ideals underlying youth care interventions undiscussed. In this article we will present our case study of EQUIP as an example of the role of this “hidden curriculum” in youth care interventions. Qualitative research has been conducted, consisting of content analysis of documents, interviews and observations. For the analysis an existing theory on the content and structure of values is used (Schwartz, 1992). The results show that there are distinct differences in the way moral behavior is defined in a Dutch and American “version” of EQUIP. The results also suggest that a difference in value perspective might be related to the effectiveness of the program.     

Young people’s disillusionment with French education before 1968: sport,the school curriculum and social change

The quasi-revolutionary events of May 1968 have come to symbolize the generation gap between young people and their elders in France, and of contestation over social values, freedom and control. This article demonstrates that this discontent was apparent earlier in the decade, although politicians in charge of youth affairs either did not see it or chose not to publicize its existence. It focuses on debates relating to sport – and its incorporation into the teaching of physical education in lycées – because of its importance both within formal schooling and as an extra-curricular leisure activity. In 1966 François Missoffe, Minister of Youth Affairs and Sport, launched a huge inquiry into the problems facing young people, leading to the publication of an official report in 1967 which, perhaps surprisingly, had nothing to say about unrest among young people. This article aims to access the voices of young people in French lycées by mining the contents of over 2600 files of evidence that were collected during the course of the Missoffe inquiry. We argue that it is important to measure the gap between what the political and educational decision-makers presupposed about the sporting needs of young people and the views these same young people actually expressed. The article highlights examples of young people’s disillusionment with the teaching of sport and physical education, demonstrating that this not only conveyed signs of discontent with educational institutions as a whole but also a wider desire for social change that anticipated the views of angry lycéens (school pupils) in May 1968.     

Facing arrhythmia. Reconstructing time in the pandemic by the metropolitan creative classes in Poland

This paper shows how the metropolitan creative classes in Poland reacted to the changes in the organization of everyday life caused by the COVID-19 pandemic, especially its temporality and rhythmicity. The pandemic and lockdowns reorganized previous ways of experiencing and managing time. Based on our empirical research and research by other scholars, we have identified some of the most common disruptions of pandemic temporality. However, a vital element of the article is to specify how the social category we studied dealt with these disruptions. In doing so, we show that the response to the breakdown of the previous order of everyday life was to restore a sense of stability actively. We were also interested in the possible, also negative consequences of the findings for the social category under study. The empirical basis for the article are in-depth interviews conducted during the fourth phase of the ongoing research project [title anonymized], which began during the first weeks of the lockdown in Poland.     

Connectedness of complete block designs under an interference model

We consider an experiment with fixed number of blocks, in which a response to a treatment can be affected by treatments from neighboring units. For such experiment the interference model with neighbor effects is studied. Under this model we study connectedness of binary complete block designs. Assuming the circular interference model with left-neighbor effects we give the condition for minimal number of blocks necessary to obtain connected design. For a specified class of binary, complete block designs, we show that all designs are connected. Further we present the sufficient and necessary conditions of connectedness of designs with arbitrary, fixed number of blocks.     

A Euclidean Likelihood Estimator for Bivariate Tail Dependence

The spectral measure plays a key role in the statistical modeling of multivariate extremes. Estimation of the spectral measure is a complex issue, given the need to obey a certain moment condition. We propose a Euclidean likelihood-based estimator for the spectral measure which is simple and explicitly defined, with its expression being free of Lagrange multipliers. Our estimator is shown to have the same limit distribution as the maximum empirical likelihood estimator of Einmahl and Segers (2009 Einmahl , J. H. J. , Segers , J. ( 2009 ). Maximum empirical likelihood estimation of the spectral measure of an extreme-value distribution . Ann. Statist. 37 ( 5B ): 2953 – 2989 .[Crossref], [Web of Science ®] , [Google Scholar]). Numerical experiments suggest an overall good performance and identical behavior to the maximum empirical likelihood estimator. We illustrate the method in an extreme temperature data analysis.     

Leaders perceived as distant and close. Some implications for psychological theory on leadership

This paper deals with some principles derived from the concept of psychological distance, which are relevant to the differential view of distant and close leaders as perceived by the followers. The claim is that psychological distance is a subjective dimension that affects the manner of construal and attributions with regard to leaders. The more distant the leaders in the followers' perception the more they will be construed in abstract categories; more weight will be attributed to them in explaining occurrences of events; the followers will relate more to their traits and less to their behaviors, and will derive from their image more meaning for their own self worth. The theoretical and empirical significance of these arguments is discussed in the paper.
