石景山制铁所相关数据考

本文通过考证,修正日本侵略者统治石景山制铁所时的三项重要数据。这些数据曾长期被广泛使用,具体为1944年3月发生31812起事故,是由于读错了文献,将当月所有员工的事假统计当作事故来理解;日本统治下的石景山制铁所占石景山地区的土地面积应该是1676228平方米(1.676228平方公里),为有关出版物所述的35000亩(23.331平方公里)的7.18%;石景山制铁所员工最多时是1944年10月,为2.4万人,不是有关出版物所述的5.9万人。     

关于农民土地权益若干问题的思考

通过对我国改革开放以来仅靠政策支持和财政投入并未使农业落后状况得到根本改变的历史事实的阐述,文章提出将土地权益关系的改革作为增加农民收入、加快农业发展的重要途径,并提出加强土地立法、明确土地制度中的权益关系、规范土地交易、加快土地权益证券化等与土地权益相关的政策建议,以期为实现社会主义新农村的目标提供必要的思路。     

土地征用制度改革探析

土地问题是城镇发展建设和城市化过程中的热点问题,土地使用制度的改革关系到城市的发展和土地使用者的切身利益。通过对当前土地征用过程中存在的问题和原因的分析,进而提出了一种新的土地使用制度———土地征购制。     

字母词在当代汉语中使用状况的分析

随着科学技术的迅猛发展以及国际交流的日益加深,加之互联网的促动,当代汉语与外语特别是英语的接触进入了前所未有的深广阶段。当代汉语中出现了大量的字母词。字母词是一个原型概念,根据字母词的概念原型,求证出字母词的4个形式指标,由此我们可以得出字母词的15种基本形式。外文原词不具有字母词的任何形式指标,不是字母词。六百万字样本语料库共出现字母词6068词次;平均每种报纸每天出现144.48词次字母词。新闻语体中字母词的平均使用密度为0.711。科技领域的使用密度最高,其次是教育领域;再次是经济领域,军事领域和政法领域使用密度最低。字母词的使用密度和文章领域相关,和地域及报纸性质不相关。     

试论劳动价值与效用价值的数量关系

劳动价值论和效用价值论是关于价值决定的两个最具代表性的理论,一般认为二者是互不相容的。文章从不易产生歧义的“使用价值”概念出发,把自然界和人类劳动对价值的贡献区别开来,进一步澄清了价值相关概念,并发现劳动价值与人工效用在数量上总是相等的。如果把劳动价值论和效用价值论融合起来,价值决定理论可能更为完整。     

Purpose and life satisfaction during adolescence: the role of meaning in life,social support,and problematic digital use

This study examined the characteristics of youth with different types of purpose in life, as well as the associations between adolescents’ life satisfaction, purpose in life, meaning in life, social support, and problematic digital use. The sample included 193 participants aged 14–18 who completed self-report questionnaires on life satisfaction, purpose in life, meaning in life, social support, and problematic digital use. The following purpose in life clusters were found: (1) other-oriented goals (n?=?33); (2) self-oriented goals (n?=?42); and (3) both other- and self-oriented goals (n?=?107). Adolescents with both self- and other-oriented goals had significantly higher life satisfaction, meaning in life, and social support compared to the other groups. Meaning in life and greater support from parents and teachers were significantly associated with greater life satisfaction. In addition, having other-oriented goals was associated with lower life satisfaction. Finally, support from parents (p?=?0.05) mediated the association between problematic digital use and life satisfaction. Findings are discussed in light of previous research and the theoretical and practical implications are examined.     

Using a community-created multisite evaluation to promote evaluation use across a sector

Multisite evaluation has been cited as a strategy for building knowledge about a program's success and enhancing evaluation capacity and evaluation use. Even so, the extent to which data from these efforts are made available to individual project participants varies. This article describes a community-created multisite evaluation that was designed to overcome this limitation. Based on the negotiated centralized evaluation model and implemented within the context of a community of practice, the EvalFest community-created multisite evaluation has used shared measures to collect data from 30,000 participants from partner sites across the community over three years. This article describes the design characteristics of the community-created multisite approach, and presents results related to partners’ evaluation use that demonstrate the early success of this method. We conclude by considering how this strategy might be applied to other sectors.     

Patterns of alcohol use and marijuana use among students at 2- and 4-year institutions

Objective: The objective of this study was to understand substance use patterns of alcohol, marijuana, and simultaneous alcohol and marijuana (SAM) use among 2- and 4-year college students. Participants: Participants were 526 young adults aged 18–23 (n?=?355 4-year students; n?=?171 2-year students) recruited from February 2015 to January 2016 who were participating in a larger longitudinal study. Methods: Latent class analysis (LCA) was used to identify past-month classes of alcohol, marijuana, and SAM use. Results: Among both 2- and 4-year students, a four-class solution yielded the best-fitting model, with 2-year classes tending to include greater marijuana use and less alcohol use and 4-year classes tending to include heavy alcohol use. Demographic characteristics were largely similar across classes. Conclusions: Classes of alcohol, marijuana, and SAM use differed by education status. Screening and prevention efforts for 4-year students may need to be tailored for the needs of 2-year students.     

Sexual Health Services for Homeless Youth: A Qualitative Analysis of their Experiences

The sexual health problems experienced by homeless youth bring into question their use of available sexual health services. Using a qualitative typological analysis, this study aims to identify sexual health services utilization profiles for homeless youth, and to understand the role of the homeless experience on the utilization of sexual health services. Individual interviews were conducted with 33 homeless youth (17 men, 16 women) between 18 and 25?years of age. Typological analysis identified four profiles: (1) a targeted use of sexual health services to determine one’s serological status following a relational change during the homeless experience; (2) a limited use of sexual health services to manage sexual emergencies that arise during the homeless experience; (3) a regular use of sexual health services to avoid the risks associated with the homeless experience; (4) a frequent use of sexual health services to obtain support when engaging in prostitution during the homeless experience. This study shows that the precarious and unstable conditions within the homeless experience incite youth to utilize sexual health services in different ways. These findings point to the importance of rethinking sexual health services to better adapt them to the different utilization profiles of homeless youth.     

Building inclusion,maintaining marginality: how social and health services act as capital for young substance users

This paper draws on Bourdieusian concepts to examine the social mechanisms driving service ‘choices’ for marginalised young substance users. In doing so, it problematises the individualised understandings of ‘choice-making’ common in the existing literature. The paper uses interview data collected from 26 young substance users to describe the resources they bring to their service encounters, the capitals that they acquire through these interactions, and the ways in which these are mobilised within the fields in which they operate. The analysis finds that services acted as capital-building settings – participants acquired material resources and opportunities for skill-building, and they built relationships that contributed to a positive sense of identity and belonging. But the exchange potentials attached to these capitals were restricted by the logics of service fields that cast them as deficit and limited their opportunities to build productive forms of social capital. By revealing the social mechanisms behind service ‘choices’, the analysis suggests that the most effective services are those that maximise the opportunities for their young clients to build ‘weak ties’, such as with a diverse range of adults who themselves possess resources, and those that acknowledge the identities that young people already possess as rational and self-managing.
