Utilizing Bayesian predictive power in clinical trial design

The Bayesian paradigm provides an ideal platform to update uncertainties and carry them over into the future in the presence of data. Bayesian predictive power (BPP) reflects our belief in the eventual success of a clinical trial to meet its goals. In this paper we derive mathematical expressions for the most common types of outcomes, to make the BPP accessible to practitioners, facilitate fast computations in adaptive trial design simulations that use interim futility monitoring, and propose an organized BPP-based phase II-to-phase III design framework.     

“I Really Belong Here”: Civic Capacity-Building among Returning Citizens

This article focuses on unlikely movement actors whose civic engagement has been understudied: people with criminal records (“returning citizens”). We present findings from 18 months of ethnographic research with members (leaders) of Fighting to Overcome Records and Create Equality (FORCE), a civic group led by returning citizens. FORCE leaders received institutional support from Community Renewal Society (CRS), a larger faith and community-based organization, to lead a rights reform movement in Chicago. Findings suggest that FORCE leaders constructed notions of kinship, recognition, and power through civic capacity-building efforts—and that social belonging was core to such capacity-building efforts. While bonding social belonging occurred as FORCE leaders formed kinship with people facing similar social and economic marginality, bridging social belonging emerged as leaders felt recognized by CRS staff organizers, affiliates, and elected officials. Bonding and bridging social belonging enabled FORCE leaders, who faced constant social exclusion in society, to experience much needed kinship, recognition, and power. Future studies should continue to uncover how local capacity-building processes have life-changing relational effects on movement participants from socially and economically marginalized groups.     

BIG DATA AND BIG CITIES: THE PROMISES AND LIMITATIONS OF IMPROVED MEASURES OF URBAN LIFE

New, “big data” sources allow measurement of city characteristics and outcome variables at higher collection frequencies and more granular geographic scales than ever before. However, big data will not solve large urban social science questions on its own. Big urban data has the most value for the study of cities when it allows measurement of the previously opaque, or when it can be coupled with exogenous shocks to people or place. We describe a number of new urban data sources and illustrate how they can be used to improve the study and function of cities. We first show how Google Street View images can be used to predict income in New York City, suggesting that similar imagery data can be used to map wealth and poverty in previously unmeasured areas of the developing world. We then discuss how survey techniques can be improved to better measure willingness to pay for urban amenities. Finally, we explain how Internet data is being used to improve the quality of city services. (JEL R1, C8, C18)

Death and the Penguin: modularity,alienation and organising

ABSTRACT

The originality of this paper lies in the ways in which it explores how the depiction of organised crime within Andrey Kurkov’s novel Death and the Penguin can inform our understanding of organisational modularity. This non-orthodox approach might open up new avenues of thought in the study of organisational modularity while further illustrating how novelistic worlds can inform accounts of organisational realities. Two main research questions underlie the paper. How can Andrey Kurkov’s novel further our understanding of the complexity of organisational worlds and realities by focusing our attention on different landscapes of organising? How does Kurkov’s novel help us grasp the concept of modularity by drawing attention to new forms of modular organisation? Drawing from our reading of Kurkov’s novel, we primarily explore organisational modularity through Kurkov’s depiction of organised crime and consider the themes of alienation and isolation in the context of modular organising.     

Technical and vocational education and training in Uganda: A critical analysis

This article undertakes a diagnostic study of the Technical and Vocational Education and Training (TVET) sub‐sector in Uganda, with a view to characterizing the sub‐sector and identifying its potential strengths and weakness. We undertook a cross‐sectional pre‐survey of purposively selected key stakeholders in the TVET sub‐sector. We selected performance indicators following their importance in influencing the TVET reform process. Both qualitative and quantitative data was solicited from the stakeholders. Quantitative data was collected through stakeholder‐specific structured questionnaires, whilst qualitative data was collected through desk review and field visits, individual focused interviews and focus group discussions. Our findings indicate that financing and planning constraints have resulted in poor quality equipment, under‐ and ill‐trained staff, limited adoption of a competence‐based education and training (CBET) curriculum, not to mention the supervision inadequacies of TVET institutions. Besides, the limited TVET sub‐sector interaction with the private sector has incapacitated TVET curriculum development to nurture skills demanded by the private sector. Furthermore, backward technology use in the private sector has equally inhibited the success of student attachment programmes. Finally, legal ambiguities have perpetuated a qualification jungle and overlapping curricula.     

Forced Sexual Experiences and Sexual Situation Self‐Efficacy Among South African Youth

Nearly 20% of South African youth experience forced or coerced sexual intercourse. Understanding the factors associated with forced sex is important for informing prevention programs aimed at reducing sexual violence and HIV and AIDS. Multilevel regression models test the association between sexual situation self‐efficacy and forced sex among 2,893 South African adolescents. Findings suggest that youth are more likely to experience forced sex after periods of time when their levels of self‐efficacy are lower than their average levels of self‐efficacy. Furthermore, youth who are lower on their self‐efficacy compared to their peers are more likely to experience forced sex. Implications for prevention research are discussed.     

“It’s a generosity loop”: Religious and spiritual motivations of volunteers who glean produce to reduce food insecurity

Food insecurity is a common social issue and households look to assistance from food pantries, which often have difficulty supplying fresh or nutritious food. A substantial amount of produce is left in the fields, which can be collected through gleaning. In a focus group with volunteer gleaners at a faith-based nonprofit organization that attempts to fill the gaps of food insecurity, the motivations, challenges, and benefits of volunteering were examined. Volunteering in gleaning generated a sense of collective purpose and community; it addressed deeply held religious and spiritual impulses; and it puts volunteers directly in contact with nature.     

Friends in Old Age

Psychoanalysis has long recognized the vital role that relationships between people play in human development and in the maintenance of sense of well being throughout life. While the internalization of representations of significant others and their interactions with each other, the achievement of object constancy, makes it possible to gain support from the realization that we live in the minds of others and they in ours’, it is “not enough.” We need people “in the flesh” from “cradle to grave.” Unfortunately, this need is more difficult to meet in our later years. Parents, siblings, mates, love partners die. Children move away. No longer do we have daily contact with our work colleagues. Old friends are lost, never to be replaced, making the ability to form and maintain additional friendships as well as the opportunity to do so critical in the life of the elderly. This paper considers the roles that friends play in old age, the developmental achievements that contribute to the capacity for friendship, some of the factors that may impede doing so, and finally the ways in which psychoanalytic treatment may foster an individual’s ability to be a friend and make friends.
