Lessons from the Niagara Movement: Prosopography and Discursive Protest

This article uses a case study of the Niagara Movement, which functioned from 1905–1910, to demonstrate that the use of prosopography (collective biographies) is a propitious methodological tool, particularly for those interested in the social-psychological analysis of movement actors within networks. I present a prosopography of the founders of the Niagara Movement. Learning more about the identity of political actors provides clues to the ways strategic choices are made and how collective action frames are developed. The prosopography of the Niagara Movement also provides theoretical insights into discursive processes that are often lost in studies of long movement trajectories. I analyze potential explanations for the absence of organizations such as the Niagara Movement from the civil rights canon, and, through an analysis of talk as a resource for mobilization, pinpoint directions for future researchers interested in micro theories of mobilization.     

Community exercise program for older adults recovering from hip fracture: a pilot study

Community-based rehabilitative exercise programs might be an effective means to improve functional outcomes for hip-fracture patients. The purpose of this study was to evaluate the effectiveness of a community exercise program (CEP) for older adults recovering from hip fracture. Twenty-five older adults (mean age 80.0 +/- 6.0 years; 24 women; 71 +/- 23 days post-hip fracture) participated in this pilot study (17 exercise, 8 control). The CEP involved functional stepping and lower extremity-strengthening exercises. Control participants received only standard outpatient therapy. Measures of functional mobility, balance confidence, falls efficacy, lower extremity strength, and daily physical activity were evaluated at baseline and at 16 weeks. Improvements for self-reported physical activity, mobility, balance, and knee-extensor strength were observed for the CEP group. This study demonstrated that a CEP is beneficial for community-dwelling older adults post-hip fracture.     

Stability of Men’s Interracial First Unions: A Test of Educational Differentials and Cohabitation History

Using the 2002 National Survey of Family Growth, this study examines how cohabitation and education affect marital dissolution for White, Black and Latino heterosexual males (N = 1,395) in their first same-race or interracial union. This research suggests that a history of cohabitation, plans of marriage and education may help explain the divergent divorce patterns of interracial and same-race unions. Life table analyses and hazard modeling reveal that cohabitation and education have independent effects on marital dissolution, but neither explains the difference between interracial and same-race unions. Measures traditionally associated with divorce attenuate this difference. Subsequent analyses by racial union pairing suggest that Black men with White women and Latino men with Black women have significantly high risks of divorce.     

A Bayesian latent spatial model for mapping the cortical signature of progression to Alzheimer's disease

Prior studies have shown that atrophy in vulnerable cortical regions is associated with an increased risk of progression to clinical dementia. In this work, we utilize the longitudinal structural magnetic resonance imaging (MRI) data from the Alzheimer's Disease Neuroimaging Initiative (ADNI) to investigate the relationship between the temporally changing spatial topography of cortical thickness and conversion from mild cognitive impairment to Alzheimer's disease (AD). We develop a novel Bayesian latent spatial model that employs the spatial information underlying the thickness effects across the cortical surface. The proposed method facilitates the development of imaging markers by reliably quantifying and mapping the regional vulnerability to AD progression across the cortical surface. Simulation results showed substantial gains in statistical power and estimation performance by accounting for the spatial structure of the association. Using MRI data from ADNI, we examined the topographic patterns of anatomic regions where cortical thinning is associated with an increased risk of developing AD.     

尼泊尔林布族的社会变迁——喜马拉雅山地文化的女性视角

林布族居住在尼泊尔东部,是喜马拉雅山地民族中人口数量相对较多的一个族群。由于历史上印度高种姓阶层不断迁徙到林布族人居住的地方,林布族人被迫抵押肥沃的土地,甚至离开原住地外出谋生。挣到钱的林布族人回到家乡,不仅赎回质押的土地,还开始从事其他贸易,取代往日的头人成了地方精英。林布族人对种姓制度的认识表明了他们具有民族主义情结,但社会结构的急剧变迁又让林布族文化逐渐与印度文化趋同。林布族妇女的权力在社会结构变迁中发生了很大变化,这是经济活动和文化接触等多种因素综合作用的结果。     

Projective (2n,n,λ,1)-designs

A projective (2n,n,λ,1)-design is a set $\text{D}$ of n element subsets (called blocks) of a 2n-element set V having the properties that each element of V is a member of λ blocks and every two blocks have a non-empty intersection. This paper establishes existence and non-existence results for various projective (2n,n,λ,1)-designs and their subdesigns.     

Assumptions of social mobility research in the U.S.: The case of occupational status

This paper examines the theoretical and empirical basis for common rank-orderings of occupational roles by raters throughout the world. From an illustrative comparison of occupational stratification in Australia and the United States we conclude tentatively that (1) commonalities in the socioeconomic characteristics of occupational roles provide the basis for interplace consistencies in “prestige” scores, (2) the structure of occupational mobility in the U.S. and Australia is largely similar, (3) this similar structure of occupational stratification manifests a common socioeconomic process which defines a (the?) major component of occupational mobility in capitalist, industrial (only?) societies. We infer that “prestige” scores for occupations are fallible estimates of the socioeconomic statuses of occupation, within the context of mobility processes in (at least) the U.S. and Australia.
