毛泽东和农民:一个革命战略形成中的阶级和力量(下)

毛泽东的革命战略经常得不到全面、辩证的阐释。通常的研究不仅过于狭隘地关注于毛泽东对农民的重视,而且也很少考虑他在国家形成过程中的贡献,而这一点其实是内蕴于毛泽东革命战略中的重要维度。毛泽东对农民的重视主要是一种战略和策略的需要,毛泽东从未否认工人阶级在革命中的领导地位,毛泽东是真正的马克思主义者。     

'Mingling together': promoting the social inclusion of disabled children and young people during the school holidays

The promotion of social inclusion of disabled children and their families is currently high on the UK political agenda. Research shows that disabled children and their families are highly disadvantaged, both economically and socially. This paper reports some of the findings of a qualitative study, entitled On Holiday! , which involved analysing the views of 297 people across six local authority research sites in England including 86 disabled children and young people. The study showed that many disabled children and their families experienced high levels of social isolation and exclusion during out-of-school periods and during the school holidays in particular. The paper recounts some of the experiences of disabled young people and their families and ways in which local authorities can promote their social inclusion. We argue that disabled young people and their families can only be truly socially included and empowered when all levels of the local authority (managers, officers and elected members) recognize the rights and entitlements of disabled children and have the political will and commitment to implement them.     

Is Hypersexuality Dimensional or Categorical? Evidence From Male and Female College Samples

The recent attempt to introduce hypersexual disorder into the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5), has increased empirical scrutiny of the construct. Consensus on its definition and underlying structure remains elusive. Whereas some conceptualizations favor a categorical latent structure, others speculate that hypersexual behavior is dimensional. Research on the latent structure of hypersexual behavior, however, has been sparse. This is unfortunate, because determination of the latent structure can contribute to more accurate assessment, diagnosis, and understanding of etiological process. To date the only study on hypersexuality's latent structure found consistent evidence of a dimensional structure for males but less clear results for females. In the present study the Multidimensional Inventory of Development, Sex, and Aggression (MIDSA), a self-report, contingency-based inventory, was administered to 1,146 college students. Four indices of hypersexual behavior and six indices of sexual compulsivity were analyzed, using three taxometric methods (mean above minus below a cut [MAMBAC], maximum covariance [MAXCOV], and latent mode factor analysis [L-Mode]). Evidence supported a dimensional latent structure for hypersexuality in male and female samples. Future assessments of hypersexuality must focus on adequate reliability and discriminant validity across the continuum of sexual behavior rather than on attempts to differentiate between arbitrarily developed diagnostic categorizations.     

Rural versus urban residence as an influence on grandparent caregivers’ needs for service

The present study explored the impact of rural (n = 26) versus urban (n = 49) environments on perceived needs for services among grandparent caregivers, wherein persons participated in focus groups targeting their needs and concerns and/or completed a mailed survey. While findings suggested substantial similarity across rural and urban persons in unmet needs, areas of difficulty, and service barriers, rural grandparents who reported their health to be fair or poor reported the greatest unmet needs and experienced the widest array of problem areas, while the opposite was true for urban grandparent caregivers. With few exceptions, sociodemographic factors failed to predict unmet needs, array of problem areas, and barriers. The practice and policy implications of these findings are discussed.     

Soil health as a predictor of lettuce productivity and quality: A case study of urban vacant lots

Urban agriculture offers a framework for local self-reliance and resilience in cities. However, there is a concern over the capacity of urban soil to provide sustainable and safe food production. We tested the effectiveness of several soil health indicators to predict food crop productivity and quality in vacant lots in a disadvantaged neighborhood in the city of Cleveland, Ohio. We defined soil health as a state of composite well being in terms of biological, chemical, and physical properties of the soil as they relate to crop productivity. Twelve city-owned vacant lots, three close to each of the four city schools, were selected for soil properties and plant growth analyses. Soil samples were analyzed for pH, moisture content (θv), soil texture, soil organic matter (SOM), active carbon (AC), ammonium (NH₄-N), nitrate (NO₃-N), microbial biomass N (MBN), and nematode community parameters including total (TNN), bacteria-feeding (BFN), fungal-feeding (FFN), and plant-parasitic (PPN) nematodes, number of nematode genera (NNG), and nematode food web enrichment index (EI) and structure index (SI). Lettuce was planted in the selected vacant lots and its growth was documented through measures of dry biomass, numbers of leaves/plant, and complementary subjective appearance scores related to physiological status. All measured parameters varied considerably among vacant lots except soil pH. Principal components analysis revealed that among the primary soil physical, chemical, and biological parameters, soil clay, NO₃-N, MBN, SOM, AC, TNN, BFN, FFN, and PPN contributed most to the variance of the entire dataset. There were also several positive correlations among these key soil health predictor variables: AC was positively correlated with clay, SOM, MBN, TNN, BFN, FFN and PPN, and TNN was positively correlated with AC, SOM, MBN, BFN, FFN and PPN. Of the identified primary soil health indicators, only clay, SOM, and MBN positively correlated with lettuce dry biomass, which was also positively correlated with a secondary soil health indicator, the nematode food web EI. Lettuce leaf necrosis was negatively correlated with clay, AC, SOM, MBN, TNN, FFN, and PPN, and the proportion of withered leaves was negatively correlated only with SOM. It is concluded that AC, PPN, TNN, SOM, MBN, clay, and nematode food web EI can serve as important soil health indicators that have potential for predicting crop productivity and quality in urban soils. It is also concluded that lettuce can serve as an important indicator of soil health with respect to crop productivity and quality in vacant lots.     

Towards a Diagnostic Toolkit for the Language of Agency

Agency—broadly, the capacity to produce effects—is a critical aspect of human activity, yet its multifaceted character makes analysis difficult. Drawing from functional linguistics, we propose a linguistic toolkit for analyzing the degree to which and manner in which speakers represent themselves as acting intentionally and autonomously. After a brief review of relevant agency literature, we propose three sets of grammatical tools, demonstrating their efficacy with a brief case study of 4 adult secondary learners’ educational narratives. We find that our toolkit offers insight both across contexts within an individual and across individuals in a single context.     

Field Note—Developing Suicide Risk Assessment Training for Hospital Social Workers: An Academic–Community Partnership

This article describes 1 large urban pediatric hospital's partnership with a university to provide suicide assessment and management training within its social work department. Social work administrators conducted a department-wide needs assessment and implemented a 2-session suicide assessment training program and evaluation. Respondents (97.8%) indicated that the training was either helpful or very helpful in 8 suicide assessment skill-based domains. All attendees reported positive changes in perceived competence in 6 of 8 skill-based domains. A brief and time-efficient in-service training can be instrumental in augmenting hospital social worker competence in suicide risk assessment practice. This model of training program development, implementation, and evaluation is feasible, evidence-informed, and may be replicated.     

The Use of a Workshop on Group Work for Field Instructors to Enhance Students' Experience with Group Work in the Field Practicum

To enhance student's learning about group work in the field practicum, one undergraduate program provided a continuing education workshop to field instructors in which core group work content was identified as were suggestions for how they could provide appropriate learning opportunities for their students. Results suggest that such training may positively affect students' opportunities to practice group work. The findings also are consistent with previous research that has demonstrated that social work students often have only limited opportunities to practice group work in the field.
