Heavy competition in India in almost all product categories, due to diversification by large and medium companies and increased entry of multinationals, has restricted the growth of domestic companies. Previously, large companies enjoyed high profit margins by targeting premium priced products in the upper strata of Indian society. High levels of competition from equally reputed brands have not only decreased the companies' market share but also created price wars, reducing profit margins and limiting market growth. This has motivated companies to consider the lower classes and the rural segments, which they had previously ignored. By targeting these segments with products in small packs at lower price points, companies have experienced great success. At the same time, small packs also pose some challenges for the companies. This paper explains the importance of small packs for market expansion in various product categories within the Indian market, drawing on several examples to support the views of the authors.

利用中国综合社会调查和中国社会状况综合调查重复截面数据,通过年龄-时期-队列模型对居民公平感的时代变化进行分析。研究发现公平感在年龄上呈“J”型趋势;从时期效应看, 2008年公平感较高, 2010~2013年在低谷徘徊,2015年以后又开始回升;从队列视角看,建国前出生队列公平感偏低,建国后初期的队列相对较高,“50”后有所下滑,从“60”后开始公平感持续走低,到“80”后跌入低谷,但“90”后又开始升高。从1949年前后“寡且不均”到建国初期阶段的“寡且均”,再到改革开放40年快速经济增长下“不寡但不均”的社会变迁过程影响了居民的公平感。 相似文献

Abstract The debate about global distributive justice is characterized by an often stark opposition between universalistic approaches, advocating an egalitarian global redistribution of wealth (Beitz, Pogge, Barry, Tan), and particularistic positions, aiming to justify a restriction of redistribution to the domestic community (D. Miller, R. Miller, Blake, Nagel, Rawls). I argue that an approach starting from the deliberative model of democracy (Habermas) can overcome this opposition. On the one hand, the increasingly global scope of economic interactions implies that the range of individuals concerned with the redistribution of wealth should also be increasingly universal. On the other hand, the need for democratic deliberation refers to the fact that demands of justice should be contextual and should take into account the particular circumstances, needs and values of the people concerned. Both concerns can be realized simultaneously only within a multi‐layered democratic system in which redistribution is a concern at the domestic, the international and the global level. 相似文献

The analysis of reaction time (RT) distributions has become a recognized standard
in studies on the stimulus response correspondence (SRC) effect as it allows
exploring how this effect changes as a function of response speed. In this
study, we compared the spatial SRC effect (the classic Simon effect) with the
motion SRC effect using RT distribution analysis. Four experiments were
conducted, in which we manipulated factors of space position and motion for
stimulus and response, in order to obtain a clear distinction between positional
SRC and motion SRC. Results showed that these two types of SRC effects differ in
their RT distribution functions as the space positional SRC effect showed a
decreasing function, while the motion SRC showed an increasing function. This
suggests that different types of codes underlie these two SRC effects. Potential
mechanisms and processes are discussed. 相似文献

现在,等值越来越受到各考试测验机构及测量学研究人员的重视,特别是项目反应理论等值的优越性更使他们有了信心。然而,很多人却没有注意到被试能力分布形态可能给等值结果带来的影响效果及程度。本研究以项目反应理论两级记分模型的项目参数等值在不同被试能力分布形态下的结果差异作为重点,探讨被试抽样偏差可能给项目特征曲线等值带来的误差问题。研究结果表明,被试能力分布形态会显著地影响项目参数等值的系数,特别地,能力分布的偏态系数与等值方程的截距存在显著的线性相关关系,但能力分布形态的变化对等值方程中斜率的影响并不明显 相似文献

Subjects lived in a laboratory apartment for up to 30 days, engaging in ordinary activities such as reading, sewing, and artwork. The amount of time devoted to each activity was recorded and compared with periodic verbal ratings of the amount of time devoted to the activities. The verbal and observational assessments of the time distribution were very similar, but there were some discrepancies. Based on self-reports and on observation of time actually devoted to the activities, contingencies were arranged in which time devoted to one activity produced time available for a second activity. When the contingency relation was based on behavioral assessment, predictions of time redistribution were more accurate than when the relations were based on verbal assessment. The close correspondence between observed distributions of time and verbally assessed distributions was probably due to the well-specified situation and rigorous assessment methods. Contrary to some cognitive-behavioral accounts, the contingency results suggest that verbal assessment is not necessarily preferable to observation when the two make discrepant predictions. It is suggested that verbal reports might be used more often in behavior analysis in place of lengthy or difficult observations, and attention is drawn to a personality model that parallels important components of behavior analysis. 相似文献

The Journal of the Experimental Analysis of Behavior at fifty 总被引:1,自引:0,他引:1
Laties VG 《Journal of the experimental analysis of behavior》2008,89(1):95-109
The Journal of the Experimental Analysis of Behavior was founded in 1958 by a group of male psychologists, mainly from the northeastern USA and connected with either Harvard or Columbia. Fifty years later about 20% of both editors and authors reside outside this country and almost the same proportion is made up of women. Other changes in the journal include having its own website for more than a decade and now publishing online as well as on paper. A recent connection with PubMed Central of the National Library of Medicine has made possible the completely free electronic presentation of the entire archive of about 3,800 articles. 相似文献
