Learning in manufacturing organizations: what factors predict effectiveness?

This paper argues that it is possible to identify factors which pre-dispose organizations to adopt effective learning strategies and processes. It is hypothesized that effective OL is associated with: profitability, environmental uncertainty, structure, approach to HRM and quality orientation. The study focuses on forty-four manufacturing organizations, and draws on longitudinal data gathered through interviews. The findings suggest that two of these variables - approach to HRM and quality orientation - are particularly strongly correlated with measures of OL. It is concluded that effective learning mechanisms, with the potential to improve the quality of OL processes, are more likely to be established in businesses where HRM and quality initiatives are well established.     

From Natural Variation to Optimal Policy? The Importance of Endogenous Peer Group Formation

We take cohorts of entering freshmen at the United States Air Force Academy and assign half to peer groups designed to maximize the academic performance of the lowest ability students. Our assignment algorithm uses nonlinear peer effects estimates from the historical pre‐treatment data, in which students were randomly assigned to peer groups. We find a negative and significant treatment effect for the students we intended to help. We provide evidence that within our “optimally” designed peer groups, students avoided the peers with whom we intended them to interact and instead formed more homogeneous subgroups. These results illustrate how policies that manipulate peer groups for a desired social outcome can be confounded by changes in the endogenous patterns of social interactions within the group.     

Barriers to completion of advance care directives among African Americans ages 25-84: a cross-generational study

Prior studies conducted in the area of Advance Care Directive document completion in African Americans have primarily targeted the elderly who are either institutionalized in skilled nursing facilities or are members of faith communities. Few studies have been done concerning barriers to Advance Care Directive document completion that include non-elderly African Americans. The purpose of this study was to identify the common barriers to advance care directive document completion across generations of African Americans ages 25-84. Using convenience sampling among various Baptist denominations of the African-American faith community of Buncombe County, North Carolina, 40 individuals ranging in age from 25-84 participated in multiple focus group sessions. Findings revealed participants shared three common barriers: 1) surrogate decision-making, 2) lack of education concerning advance care directive discussions and completion, and 3) fear and denial. Also revealed were barriers that varied across generations: 1) fatalism, 2) mistrust of the health care system, 3) spirituality, and 4) economics.     

Infant locomotion shapes proximity to adults during everyday play in the U.S.

Learning to walk expands infants’ access to the physical environment and prompts changes in their communicative behaviors. However, little is known about whether walking also shapes infants’ proximity to their adult social partners during everyday activities at home. Here we followed 89 infants (42 boys, 47 girls; 92% White, not Hispanic or Latino) longitudinally and documented connections between infant locomotion and infant-adult proximity on two timescales: (1) across developmental time, by comparing data from a session when infants could only crawl to a later session when they could walk (M walk onset = 12.15 months, range = 8-15); and (2) in real time, by testing whether the amount of time that infants spent in motion (regardless of their locomotor status) related to their interpersonal distance to adults. The developmental transition to walking corresponded to a significant, but modest, decrease in infant-adult proximity. Infants’ moment-to-moment locomotion, however, was strongly related to patterns of interpersonal distance: infants who spent more time in motion spent less time near adults and instigated more proximity transitions, resulting in shorter and more dispersed bouts of proximity throughout sessions. Findings shed new light on how infants’ motor achievements can reverberate across other domains of development, and how changes in infant development that researchers often observe over months arise from infants’ moment-to-moment experiences.     

Like a River: The Million Man March and the Black Nationalist Tradition in the United States

This article examines the Million Man March in the wider context of black nationalism, a persistent, though inconsistent, factor in African American life, enjoying wider currency at some historical junctures than others. Those periods when black nationalism resonated strongly among African Americans are called black nationalist moments, four of which are identified here. The Million Man March, with its heavy inflection of patriarchy and black capitalism, is seen as the iconic event of the fourth moment. The subsequent Million Woman March is pivoted as a more radical and activist rejoinder to the Million Man March, a response continued by the even more recent Black Radical Congress.
