Challenges in recruiting parents to participate in child welfare research: implications for study design and research practice

Although research with hard‐to‐reach populations is necessary to deepen the social work knowledge base and improve services to these groups, recruiting members of hard‐to‐reach populations for research projects is often a challenging process. Frequently, non‐probability sampling is used to obtain participants. However, the difficulties and limitations associated with this process in quantitative research are rarely discussed in depth in the literature. Sampling issues can significantly impact a research project, delaying it, extending it or even causing the premature termination of a project. Challenges to recruitment can limit the type of research that is completed, impact the knowledge base or introduce threats to validity through sampling bias. Using a preliminary quantitative study on parental engagement with child protective services as an illustration for the discussion, the challenges of non‐probability sampling with a hard‐to‐reach population and the implications for research practice are explored and discussed. Implications for future research practice are considered.     

社区治理创新中的软法之治

相对于硬法之治,软法之治更为注重协商与民主、对话与互动,在本质上同社区治理创新的理念相契合。将软法之治引入社区治理创新中需要培育多元主体共治合作、社区行政管理组织指导服务、社区治理主体民主协商等软法治理理念。社区治理创新中的软法之治具有侧重反映社区多元治理主体共同意志,制定形式多样、简易、灵活、高效,实施依靠“利益诱导-柔性惩罚”机制,制定程序具有更高程度的民主协商性等特征。社区治理创新中法治体系的构建需要从单一的硬法治理模式转向“软硬并举”的混合法治理模式。     

‘(What's so funny ‘bout) peace,love & understanding’: rock culture and the rebuilding of civic identity in the post-conflict Balkans

The article examines current rock culture in the Balkans as a potential vehicle for rebuilding the broken sociocultural bonds between the different post-Yugoslav societies and for creating a constructive cultural space for articulating new forms of civic and post-nationalist identities. The argument offered is that, after the sociocultural exile during the war years, rock culture in the post-conflict Balkans has considerable potential to establish itself as a popular-cultural force of ‘utopian transcendence’ of the current ethno-nationalist sociopolitical moment, and as a catalyst of the new post-Yugoslav spirit of openness, tolerance and peaceful coexistence.     

利用岩电实验确定Archie公式参数变化规律的研究

针对大庆油田高含水后期开发,油层内岩性、物性、含水性都已发生变化的特点,给测井资料确定水淹层饱和度参数带来很大困难,提出用岩电实验,进行地层岩电机理分析研究,确定不同注水矿化度下岩石电阻率变化以及Archie公式参数变化规律,从而提高解释精度.     

硬质景观的色彩冥想

在园林硬质景观设计中,色彩是重要的表达方式之一。本文基于园林硬质景观的范畴,阐述了与色彩表达相关的物质性及非物质性因素,分析了园林硬质景观中色彩与光、形体之间的相关性。色彩承载了一个地域的文化内涵和其他传统意义上的痕迹,是传统园林文化中重要的表现元素。文章阐述了色彩心理学对硬质景观设计的影响,并结合典型景观实例详细分析了如何运用硬质景观的色彩划分空间、强调空间,以表达特定的场所精神。     

林伯渠与延安精神

为了分析林伯渠的人格魅力及其在延安精神建构过程中的重要贡献,运用文献分析法考察相关历史文献。研究认为,作为陕甘宁边区政府主席的林伯渠,政治方向坚定正确,是一位德高望重的革命“老战士”;注重调查研究,能够灵活地坚持原则,无私无畏地坚持实事求是的“真理卫士”;在极其困难的条件下保持革命的乐观主义精神,克勤克俭艰苦奋斗的“普通老百姓”;切实为人民谋实实在在利益的“老勤务员”;和其他优秀的战友一样,他以自己的丰富思想和实际行动为延安精神的形成做出了重要贡献,诠释了延安精神的丰富内涵,是延安精神的人格化身。     

宽严相济刑事政策的时代意义——从“严打”到宽严相济刑事政策演变角度分析

改革开放初期,为了遏制快速增长的犯罪率,我国提出了"严打"刑事政策,不仅未取得明显效果,反而出现了一些消极因素。我国宽严相济刑事政策的提出,其实质就是对纷繁复杂的刑事犯罪情况区别对待,既要做到有力打击,震慑犯罪;又要做到宽严相济,尽可能减少社会对抗,变消极因素为积极因素,实现法律效果和社会效果的统一。

Survey of feral rock doves (Columba livia) in Amsterdam, a bird-human association

We carried out a survey of the feral rock doves (Columba livia) visible in the public areas of the fourteen Town Councils in Amsterdam. The objectives were to detect the preferential locations of the feral pigeons and to obtain reference values of their population sizes in order to be able to evaluate the effect of possible control measures. We registered 354 locations were twenty or more feral pigeons were visible during feeding. In these locations, averaged over ten to twelve counts, we counted 10,056 pigeons. Moreover we observed that at another 541 locations at least once five pigeons were visible during feeding. In all 894 locations we counted, averaged over four counts, 11,885 pigeons. By Town Council, we calculated strong positive correlations between the average number of pigeons per hectare, the human population density, the number of houses and the yearly number of kilos organic waste per hectare.
