Global narratives of fatherhood. Fathering and masculinity on the Internet

There is currently an increasing amount of research on online fatherhood. In this article, we have used international blogs as our empirical data, in order to investigate and create an in-depth picture of fatherhood as it is expressed in various men’s stories about their everyday lives. Three distinct conceptions of fatherhood and masculinity emerge. The first of these positions could be described as a nostalgic position in relation to hegemonic masculinity. The second position is referred to here as complicity. This position indicates a changing landscape of fatherhood and family politics, moving towards gender-equal conditions. Thirdly, we have an inclusive position that reflects a gender-neutral position, and are understood less in terms of masculinity, heteronormativity and gender-divided responsibilities.     

Palm Distributions for Log Gaussian Cox Processes

This paper establishes a remarkable result regarding Palm distributions for a log Gaussian Cox process: the reduced Palm distribution for a log Gaussian Cox process is itself a log Gaussian Cox process that only differs from the original log Gaussian Cox process in the intensity function. This new result is used to study functional summaries for log Gaussian Cox processes.     

Geometric Anisotropic Spatial Point Pattern Analysis and Cox Processes

We consider spatial point processes with a pair correlation function, which depends only on the lag vector between a pair of points. Our interest is in statistical models with a special kind of ‘structured’ anisotropy: the pair correlation function is geometric anisotropic if it is elliptical but not spherical. In particular, we study Cox process models with an elliptical pair correlation function, including shot noise Cox processes and log Gaussian Cox processes, and we develop estimation procedures using summary statistics and Bayesian methods. Our methodology is illustrated on real and synthetic datasets of spatial point patterns.     

On the Complexity of Constructing Evolutionary Trees

In this paper we study a few important tree optimization problems with applications to computational biology. These problems ask for trees that are consistent with an as large part of the given data as possible. We show that the maximum homeomorphic agreement subtree problem cannot be approximated within a factor of , where N is the input size, for any 0 in polynomial time unless P = NP, even if all the given trees are of height 2. On the other hand, we present an O(N log N)-time heuristic for the restriction of this problem to instances with O(1) trees of height O(1) yielding solutions within a constant factor of the optimum. We prove that the maximum inferred consensus tree problem is NP-complete, and provide a simple, fast heuristic for it yielding solutions within one third of the optimum. We also present a more specialized polynomial-time heuristic for the maximum inferred local consensus tree problem.     

When do Public Managers Imitate Each Other? Mimetic Decision Making in Contracting Decisions of Danish Municipalities

Using organizational new institutional theory, this paper explores a core mechanism underlying contracting decisions in public organizations. A central proposition of this branch of institutional theory is that uncertainty leads to organizational isomorphism. The present study investigates this proposition by asking: When does perceived uncertainty lead public managers to imitative behavior in contracting out decisions? Contrary to most previous studies, we apply an individual level approach and relate different types of perceived uncertainty of decision makers to mimetic decision making. We define mimetic decision making as when decision makers deliberately obtain information about other organizations in order to possibly imitate them. In a survey of Danish municipal managers facing important and complex contracting decisions, we test our hypotheses about three types of perceived uncertainty and mimetic decision making. The results show that technological uncertainty is strongly related to mimetic decision making among public managers. However, we do not find significant results for either volume uncertainty or performance uncertainty. The paper illustrates how uncertainty, through mimetic decision making, is connected to organizational isomorphism. It further highlights that future studies should pay attention to the multidimensionality of uncertainty and its consequences.     

Income Inequality and Subjective Well-being: A Cross-National Study on the Conditional Effects of Individual and National Characteristics

In this study we raise the question how a nation’s income inequality affects subjective well-being. Using information on 195,091 individuals from 85 different countries from the World Value Surveys and the European Value Surveys, we established that in general, people living in more unequal countries report higher well-being than people from more equal countries. This association however does not apply to all people similarly. First, the positive effect of a nation’s income inequality is weaker when individuals express more social and institutional trust, and underscore egalitarian norms to a larger extent. Second, the positive association between national income inequality and subjective well-being is less strong for people from countries with high levels of social and institutional trust. So, our research predominantly indicates that there are far-reaching effects of an individual’s and a nation’s trust on people’s well-being.     

Modelling columnarity of pyramidal cells in the human cerebral cortex

For modelling the location of pyramidal cells in the human cerebral cortex, we suggest a hierarchical point process in that exhibits anisotropy in the form of cylinders extending along the z-axis. The model consists first of a generalised shot noise Cox process for the xy-coordinates, providing cylindrical clusters, and next of a Markov random field model for the z-coordinates conditioned on the xy-coordinates, providing either repulsion, aggregation or both within specified areas of interaction. Several cases of these hierarchical point processes are fitted to two pyramidal cell data sets, and of these a final model allowing for both repulsion and attraction between the points seem adequate. We discuss how the final model relates to the so-called minicolumn hypothesis in neuroscience.     

Space-time Multi Type Log Gaussian Cox Processes with a View to Modelling Weeds

Log Gaussian Cox processes as introduced in Moller et al. (1998) are extended to space-time models called log Gaussian Cox birth processes. These processes allow modelling of spatial and temporal heterogeneity in time series of increasing point processes consisting of different types of points. The models are shown to be easy to analyse yet flexible enough for a detailed statistical analysis of a particular agricultural experiment concerning the development of two weed species on an organic barley field. Particularly, the aspects of estimation, model validation and intensity surface prediction are discussed.     

Anthony Giddens and public relations: A third way perspective

In the article, the main theories of Anthony Giddens (structuration and late modernity theory) are presented and applied upon public relations. A review shows that there have been few attempts to use these theories in public relations. The analysis states that using Giddens leads to a questioning of the dichotomy between instrumental agency-oriented theories that neglects power structures as well as critical theories that only views public relations as hidden strategic action used by elites to dominate the public sphere. The conclusion is that there are two major arguments for applying Giddens to public relations: (1) the theory of late modernity may enhance our understanding of public relations as an evolving practice in socio-historical and spatial terms; (2) the structuration theory enhances the holistic understanding of how public relations communication, interpreted as a process, may be used both as a reproductive and a transforming social instrument. Giddens theory may in other words be used as a “third way public relations theory”.
