从殖民和后殖民的角度看现代性问题

全球范围内殖民主义体系的崩溃，使现代性具有了多义性和混乱性。这证明了西方现代性本身存在着矛盾性和含混性，也说明了西方现代性的对立面——反殖民主义和现代性的效颦者——更加深了现代性本身的矛盾性和含混性，表现出对资本主义工业（或后工业）社会所设想的现代文明的质疑与抗议。     

An alternative to farmer age as an indicator of life-cycle stage: The case for a farm family age index

In studies of farming, the age of the principal decision-maker (PDM) has been associated with numerous farm structural and managerial features and has been widely accepted as a good indicator of the influence of life-cycle factors on decision-making. As such, it has become an important aspect of many quantitative studies of agricultural change. However, contemporary studies of family farming demonstrate that the concept of a single PDM in family farms is becoming an anachronism as alternative enterprises, pluriactivity and the scale of family farms force more diffuse management/operating systems. This raises questions concerning whether the age of the PDM can still be taken as representative of farm structure, strategy or life-cycle stage? Using a study conducted in the Grampian Mountains region of Scotland in 2003 this note investigates the impact of using an alternative index—compiled by averaging the age of family members working on the farm. It suggests that PDM age is a relatively poor indicator of farm structural and managerial features compared to a family age index and calls for researchers to think about alternative approaches to measuring ‘age’ as an indicator.     

An evaluation of the childhood family structure measures from the sixth wave of the British Household Panel Survey

Summary.  The paper performs an evaluation of the data that were collected in the sixth wave of the British Household Panel Survey (BHPS) on childhood family structure. After comparing such data with a large number of studies by using external sources, we find that the BHPS data overestimate the proportion of people who report an experience of life in a non-intact family during childhood by about 10%. Although an explanation based on recall error that deteriorates with the age of the BHPS respondents is possible, the overestimation is likely to be accounted for by non-ignorable attrition that may affect most of the comparison studies based on longitudinal data. Conversely, comparisons with other independent measurements from the BHPS itself reveal that the wave 6 data underestimate the proportion of young people who have lived at least part of their childhood in a non-intact family by about 8%. The probability of disagreement between these two sets of measures is strongly associated with poor interview characteristics, which may affect the comparison measure more than the wave 6 measure. Despite such differences, there is therefore a substantial degree of similarity between the family structure information that was collected in the sixth wave of the BHPS and the host of highly diverse records against which it has been compared.     

The ecosystem blueprint: How firms shape the design of an ecosystem according to the surrounding conditions

Ecosystems are formed by organisations that jointly create a value proposition that a single firm could not create in isolation. To deliver this value proposition, the partners need a focal firm, the orchestrator, to be align them towards the joint value proposition. Thus, how orchestrators design the alignment structure of an ecosystem is at the very heart of the ecosystem concept – yet it has not been sufficiently addressed by extant research. This is all the more true for the question of how the design of an ecosystem is shaped depending on surrounding conditions. This paper applies a qualitative study with ten cases and, based on the attention-based view of the firm, contributes to research on ecosystems in several ways. First, it explains which ecosystem designs are beneficial under which conditions. Second, it elucidates the structure and activities within ecosystems and shows that start-ups can be just as good ecosystem orchestrators as incumbents. Third, it explains the circumstances under which single vs. multi orchestrator ecosystems occur. Fourth, it presents the conditions when incumbents or start-ups make better orchestrators. Finally, it is among the first studies to apply the attention-based view to business ecosystems, and shows that doing so yields intriguing insights into this emerging field of research.     

身体缺场的个性化消费研究

通过网络平台,人们可以不受时空限制,在身体缺场的情况下进行消费。与传统线下消费相比,网络消费者的消费需求彰显出符合自身特点的个性化趋势。时空分离的缺场空间使得人们在实施某些社会行为时的心理产生了变化,由此,消费内容、消费选择及消费结构也必然发生相应的转变。身体缺场的个性化消费存在一些可能影响正常消费秩序的问题,因此,需要有针对性地建立完善的网络个性化消费监管办法和信息共享平台,健全有关法律制度体系,并加强相关技术创新。     

Family structure and child outcomes in the USA and Sweden

Previous research shows that living in a non-intact family is associated with educational disadvantages. This paper compares the relationships between childhood family structure, schooling, and earnings in Sweden and the USA. This comparison is interesting because both family structure and public policies differ significantly. We find a negative relationship between living in a non-intact family and child outcomes, and the estimates are remarkably similar in both countries. After using sibling-difference models, the correlation with family structure is no longer significant. These results cast doubt on the causal interpretation of the negative relationship between non-intact family structures and child outcomes.     

知识经济与人口发展

知识经济将是经济发展的主流 ,它要求社会对科技有巨大的投入 ,而这种投入对经济和社会有更大的回馈 ;知识产业将成为经济结构中的主导产业 ;知识经济以知识价值为核心 ;在知识经济时代世界经济将形成全球化的新格局 ,并对传统产业进行技术改造。知识经济时代对人口数量的制约因素将主要是环境的和空间的适度 ;对提高人口素质的要求更为迫切 ;人口的经济结构将发生重要变化 ,知识工人将成为社会的主导力量 ;人口分布与迁移也将出现集中化分散化的新特点。知识经济对人口学研究提出了更高要求 ,人口学研究手段要实现现代化和信息化 ;人口学要开放化

稳定低生育水平与中国家庭养老关系的再思考

稳定低生育水平不会对家庭养老功能带来负面影响。主要理由是 :1.衡量家庭养老功能的标准已经变化。2 .家庭养老的本质是国家性家庭养老。 3.稳定低生育水平与家庭养老的关系不是单因素对单因素的关系 ,而是系统与系统的关系     

吉林省城乡居民消费变化的特点及差异研究

随着城乡居民收入的提高 ,吉林省居民的消费水平有了显著变化 ,按可比价格计算的居民消费水平指数总体上呈上升趋势。进入 90年代以来 ,居民的消费构成也相应发生了很大的转变 ,但城乡之间仍然存在较大的差异。实践表明 ,在经济发展水平相对较高的条件下 ,居民消费的心理、水平、构成及其变化 ,对经济增长的影响力度势必呈现出越来越大的趋势
