Networks as Resources, Organizational Logic, and Change Mechanism: The Case of Private Business Schools in Post-Socialism

The paper differentiates between three conceptualizations of organizational networks: as resources, as organizational logic, and as a change mechanism. We integrate and apply these conceptualizations in one of the first comprehensive studies of private business schools in post-socialism. Using case studies, content analysis of websites, and an open-ended survey of administrators, we show how East-West networks helped in establishing a new type of organization at the end of socialism, how schools use networking as a core organizational principle to enhance efficacy and legitimacy, and how their activities help build capitalism from the bottom up by transmitting market-based knowledge to post-socialist economic actors.

The characterization of Monte Carlo errors for the quantification of the value of forensic evidence

Recent developments in forensic science have lead to a proliferation of methods for quantifying the probative value of evidence by constructing a Bayes Factor that allows a decision-maker to select between the prosecution and defense models. Unfortunately, the analytical form of a Bayes Factor is often computationally intractable. A typical approach in statistics uses Monte Carlo integration to numerically approximate the marginal likelihoods composing the Bayes Factor. This article focuses on developing a generally applicable method for characterizing the numerical error associated with Monte Carlo integration techniques used in constructing the Bayes Factor. The derivation of an asymptotic Monte Carlo standard error (MCSE) for the Bayes Factor will be presented and its applicability to quantifying the value of evidence will be explored using a simulation-based example involving a benchmark data set. The simulation will also explore the effect of prior choice on the Bayes Factor approximations and corresponding MCSEs.     

Bibliometric Network Analysis and Visualization for Serials Librarians: An Introduction to Sci2

ABSTRACT

Bibliometric data have the potential to inform collection development, describe institutional scholarship strengths and citation patterns, and suggest potential areas of research collaboration. This article introduces methods of using data from citation databases to generate bibliometric analyses of journal titles, subject matter, and coauthorship networks using the open software tool Science of Science (Sci2). These analyses can be used to enhance responsive institutional and network collecting and to connect users to additional research and publication partners.     

Indigenous perspectives for strengthening social responses to global environmental changes: A response to the social work grand challenge on environmental change

ABSTRACT

The “Grand Challenges for Social Work,” is a call to action for innovative responses to society’s most pressing social problems. In this article, we respond to the “Grand Challenge” of Creating Social Responses to a Changing Environment from our perspective as Indigenous scholars. Over the last several decades, diminishing natural resources, pollution, over-consumption, and the exploitation of the natural environment have led to climate change events that disproportionately affect Indigenous peoples. We present how environmental changes impact Indigenous peoples and suggest culturally relevant responses for working with Indigenous communities. We propose a decolonizing cyclical, iterative process grounded in Indigenous Ways of Knowing.     

Single-Stop Ebook Reader “SimplyE”: Is It APPlicable for Academic Libraries?

Accessing ebooks from different vendors often requires switching between multiple platforms, which can be unwieldy for library users. To offer readers a coherent and seamless reading experience, the New York Public Library (NYPL) initiated a project called SimplyE (or LibrarySimplified). The end user deliverable of this project is an application (Android, iOS) that enables users to read ebooks from multiple vendors through a single interface, thereby delivering a Netflix-style experience for searching, browsing, and checking out ebooks. The back end consists of applications that manage ebook collections, circulation, and metadata for libraries. This column explores the viability of implementing SimplyE in an academic library setting.     

Forced migrations and Externalization of European Union Border Control: Serbia on the Balkan Migration Route

The article argues that the recent “migration crisis” has been constructed as a security threat to the European Union, which conceals both the multiple causes of forced migrations, and the inability of the Union to respond to the massive influx of people in need of protection. Serbia had taken up a “refugee-friendly” policy, which implied a humanitarian approach. However, due to a change of political discourse in connection with the EU accession, a shift towards the security position occurred. This article sheds light on the actual status of migrants and asylum seekers in Serbia, as well as the state response to the growing challenges in the area of acceptance and protection, following the official closure of the Balkan route. In the conclusion, the authors tentatively plead for return to a balanced humanitarian approach, since there is clear evidence that mixed migration flows will resume in the times to come.     

On the radius of centrality in evolving communication networks

In this article, we investigate how the choice of the attenuation factor in an extended version of Katz centrality influences the centrality of the nodes in evolving communication networks. For given snapshots of a network, observed over a period of time, recently developed communicability indices aim to identify the best broadcasters and listeners (receivers) in the network. Here we explore the attenuation factor constraint, in relation to the spectral radius (the largest eigenvalue) of the network at any point in time and its computation in the case of large networks. We compare three different communicability measures: standard, exponential, and relaxed (where the spectral radius bound on the attenuation factor is relaxed and the adjacency matrix is normalised, in order to maintain the convergence of the measure). Furthermore, using a vitality-based measure of both standard and relaxed communicability indices, we look at the ways of establishing the most important individuals for broadcasting and receiving of messages related to community bridging roles. We compare those measures with the scores produced by an iterative version of the PageRank algorithm and illustrate our findings with three examples of real-life evolving networks: the MIT reality mining data set, consisting of daily communications between 106 individuals over the period of 1 year, a UK Twitter mentions network, constructed from the direct tweets between \(12.4\) k individuals during 1 week, and a subset of the Enron email data set.     

Trajectory Discrimination and Peripersonal Space Perception in Newborns

The ability to discriminate the trajectories of moving objects is highly adaptive and fundamental for physical and social interactions. Therefore, we could reasonably expect sensitivity to different trajectories already at birth, as a precursor of later communicative and defensive abilities. To investigate this possibility, we measured newborns' looking behavior to evaluate their ability to discriminate between visual stimuli depicting motion along different trajectories happening within the space surrounding their body. Differently from previous studies, we did not take into account defensive reactions, which may not be elicited by impending collision as newborns might not categorize approaching stimuli as possible dangers. In two experiments, we showed that newborns display a spontaneous visual preference for trajectories directed toward their body. We found this visual preference when visual stimuli depicted motion in opposite directions (approaching vs. receding) as well as when they both moved toward the peripersonal space and differed only in their specific target (i.e., the body vs. the space around it). These findings suggest that at birth human infants seem to be already equipped with visual mechanisms predisposing them to perceive their presence in the environment and to adaptively focus their attention on the peripersonal space and their bodily self.
