The latest financial crisis has stressed the need of understanding the world financial system as a network of interconnected institutions, where financial linkages play a fundamental role in the spread of systemic risks. In this paper we propose to enrich the topological perspective of network models with a more structured statistical framework, that of Bayesian Gaussian graphical models. From a statistical viewpoint, we propose a new class of hierarchical Bayesian graphical models that can split correlations between institutions into country specific and idiosyncratic ones, in a way that parallels the decomposition of returns in the well-known Capital Asset Pricing Model. From a financial economics viewpoint, we suggest a way to model systemic risk that can explicitly take into account frictions between different financial markets, particularly suited to study the ongoing banking union process in Europe. From a computational viewpoint, we develop a novel Markov chain Monte Carlo algorithm based on Bayes factor thresholding.

Donna L. Van Raaphorst provides a detailed statistical analysis of a large sample of Alcatraz Prison inmates using the Social Science Statistical Package. The data, drawn directly from the inmate files, is compared whenever possible with similar data provided by the Bureau of Prisons in order to determine if Alcatraz, often regarded as America's Devil's Island, really incarcerated the so-called “Worst of the Worst” in its time. The results would seem to indicate that Alcatraz inmates were, in fact, not remarkably different from those in any other Federal prison in the system.

This chapter seeks to increase our understanding of health care employees' perceptions of effective and ineffective leadership behavior within their organization.

Interviews were conducted with 59 employees working in a diversity of positions within the case study hospital. Interviewees were asked to cite behaviors of both an effective and an ineffective leader in their organization. They were also asked to clarify whether their example described the behavior of a formal or informal leader. Grounded theory data analysis techniques were used and findings were interpreting using existing leadership behavior theories.

(1) There was a consistent link between effective leadership and relationally oriented behaviors. (2) Employees identified both formal and informal leadership within their hospital. (3) There were both similarities and differences with respect to the types of behaviors attributed to informal versus formal leaders. (4) Informants cited a number of leadership behaviors not yet accounted for in the leadership behavior literature (e.g., ‘hands on’, ‘professional’, ‘knows organization’). (5) Ineffective leadership behavior is not simply the opposite of effective leadership.

Findings support the following ideas: (1) there may be a relationship between the type of job held by employees in health care organizations and their perceptions of leader behavior, and (2) leadership behavior theories are not yet comprehensive enough to account for the varieties of leadership behavior in a health care organization. This study is limited by the fact that it focused on only those leadership theories that considered leader behavior.

There are two practical implications for health care organizations: (1) leaders should recognize that the type of behavior an employee prefers from a leader may vary by follower job group (e.g., nurses may prefer relational behavior more than managerial staff do), and (2) organizations could improve leader development programs and evaluation tools by identifying ineffective leadership behaviors that they want to see reduced within their workplace.

Health care organizations could use these findings to identify informal leaders in their organization and invest in training and development for them in hopes that these individuals will have positive direct or indirect impacts on patient, staff, and organizational outcomes through their informal leadership role.

This study contributes to research and practice on leadership behavior in health care organizations by explicitly considering effective and ineffective leader behavior preferences across multiple job types in a health care organization. Such a study has not previously been done despite the multi-professional nature of health care organizations.

Applying sociological and developmental theoretical perspectives to educational policy issues, this study analyzed data from 7,710 children from low-income families in the Early Childhood Longitudinal Study-Kindergarten Cohort. The goal was to examine how much the association between phonics instruction in kindergarten classrooms and children’s reading achievement during the first year of school in the low-income population would depend on whether children had previously attended preschool as well as the socioeconomic composition of their elementary schools. Lagged linear models with a series of sensitivity tests revealed that this association was strongest among children from low-income families who had not attended preschool and then enrolled in socioeconomically disadvantaged elementary schools and among children from low-income families who had attended preschool and then enrolled in socioeconomically advantaged elementary schools. These findings demonstrate how insights into educational inequality can be gained by situating developing children within their proximate ecologies and institutional settings, especially looking to the match between children and their contexts. They are especially relevant to timely policy discussions of early childhood education programs, classroom instructional practices, and school desegregation.

Our paper discusses simulation-based Bayesian inference using information from previous draws to build the proposals. The aim is to produce samplers that are easy to implement, that explore the target distribution effectively, and that are computationally efficient and mix well.

Due to impressive market growth over several decades, consulting can today be regarded as an influential industry. In spite of this success, consulting is confronted with prejudices, which, to some extent, can be linked to difficulties in the evaluation of consulting services. By guaranteeing certain qualification levels, professionalism is generally considered useful for reducing this kind of uncertainty. In this chapter, using a German case as an example, we analyze professionalization efforts among consultants. We argue that these efforts will never be successful if the classical concept of professionalism is applied. However, seen from the perspective of the “new professionalism” that concentrates on work behaviour, consultants qualify as highly professional.

During the months leading up to and immediately following President Donald Trump’s election, the unique intersection of classroom academic freedom and teacher and students’ first amendment rights would be duly tested, as headlines reminded citizens, parents, and pundits that the reach of raw emotions and political viewpoints did not stop at the schoolhouse door. School and classroom-based events would eventually test the norms of community, the interpretation of legal precedents, the resolve of district and school leadership, and the rights or limits thereof of the teachers themselves. This analysis is grounded on case studies of eight such incidents, all of which occurred at the high school level in public school districts. These eight cases are analyzed in terms of the incidents, the teacher’s actions or speech, the consequences, the relevant legal precedents surrounding academic freedom, the parental, student, and community reaction, and the short- and long-term impacts moving forward.
