Models of economic planning under uncertainty: A selective survey and appraisal

Uncertainty and risk have played significant roles in policy making, at the micro and macro levels, from formulation of policy models to their actual implementation in several countries. The impact of risk aversion on policy making has differedm however, both in magnitude and intensity. Thus, for less developed countries with large commodity exports, stabilization policies have played a role as important as those for income growth and employment; for centrally planned economies, the investment cycles leading to large-scale divergences of actual from planned targets in strategic sectors have led policy makers to consider the need for building adequate safety margins in the planning process. Finally, for developed economies, the applied theory of indicative planning and decentralization has stressed the various informational gaps and competing risks that may impede an efficient and cooperative solution between private and public sectors. A selective survey and appraisal of the planning methods as they relate to risk and uncertainty is attempted here for less developed, centrally planned, and developed market economies.     

Masstige model and measure for brand management

The purpose of this article is to reconceptualize the term “masstige” (Mass Prestige) marketing, develop a masstige model for brand management, and extend the use of the Masstige Mean Scale (MMS). The study was conducted based on the data from 600 individuals living in the United States, France, and India using a structured questionnaire consisting of different factors/sources of brand equity, such as mass prestige, brand knowledge, and perceived quality. On the basis of the findings, we establish that the greater the brand's Masstige Mean Index (MMI) value (“MMIV”), the higher the potential customers' top-of-mind brand awareness. Low MMIVs imply that firms have a long way to go to build their brands. We argue that MMI may allow firms to measure brand equity in different regions, within a country or in foreign countries, to derive insights into the popularity of their brands. We posit three theoretical propositions and develop two theoretical models (i) a hexagon model and (ii) a three-stage model for masstige marketing to define, reconceptualize, and explain the phenomenon.     

Input-output technologies and the effects of tariff reductions

Using input-output (IO) tables from several developed countries (United States, EEC, and Japan) and one developing country (Brazil), we calculate the effects of tariff removal using various combinations of these tables to represent technologies for the countries included in the Michigan Computational Model of World Production and Trade. Among the IO tables, Brazil's reflected unusually high shares of value added, low labor shares, and small supply elasticities. Supply elasticities for the developed countries were somewhat lower than for the United States. Using the Michigan model, our calculated effects of tariff reductions are overstated using the U.S. IO table to represent technologies for other developed countries. Further, for developing countries that use import licensing, the model shows considerable sensitivity to IO table specification. It is especially important, therefore, for computational purposes to obtain the most accurate information possible about IO structures of developing countries.     

Aspects of a new world development strategy II: Factors affecting the long-term prospects of developing nations

This paper explores some quantitative dimensions of the interdependence of rich and poor regions in the context of the United Nations World Model. It extends the original work on that model in three ways: (1) by updating some of the key parameters and exogenous variables in the light of recent data; (2) by developing a “control” solution to be used as a point of reference in policy simulations; and (3) by exploring the sensitivities of each of two groups of regions— developed and developing—to changes in one another's growth rates. Goals of closing the income gap between developed and developing regions and of increasing income levels in the latter are discussed.     

What Changes MSW Students' View on the Mission of Social Work?

Little is known about how professional social work education affects students' view on the social work mission. Using a secondary analysis of larger longitudinal data collected from masters in social work (MSW) students in California, USA, this study sought to explore the relationship among the students' demographic characteristics, their primary reasons for pursuing an MSW degree, and their view on the mission of social work at the time of entering an MSW program, whether the students' view on the mission of social work changed in the course of an MSW education, and factors contributing to a change of MSW students' view on the social work mission—individual adaptation vs societal change—between the beginning and the end of the MSW program. The results showed that students' degree of social action involvement, type of field practicum, and ideological variables predicted students' view changes or adherence between entering the MSW program and graduating.     

Everyday people: public identities in contemporary hip-hop culture

As scholars on culture have suggested elsewhere, cooption through consumption by the music culture industry has forced those who want to be part of the hip-hop subculture to go back underground. But to label all of these individuals in the underground merely ‘hip-hop’ would be as equally uninformative as labeling anyone who wears baggy blue jeans and can rhyme words together as being hip-hop. My year of field research in Chicago revealed that five major identities emerged: Professional Headz, Refugee Headz, Hip-Hop Fundamentalists, Black Headz and Tech Headz. These identities were characterized by the personal values that my participants indicated were most reaffirmed through hip-hop culture. This article contributes to the literature on hip-hop by providing an ethnographic study on how the Hip-Hop Nation defines itself, while examining some of the tensions that these identities provide within the Hip-Hop Nation. It also reinforces the view that subculture must still be experienced in the flesh and is not fully experienced by being able to engage in the culture industry of hip-hop through purchasing records, watching videos or buying hip-hop fashions. This article also provides a more complex qualitative understanding of what values constitute being hip-hop and which ones do not.     

美国独霸世界的合纵连横战略初探 ——基于地缘政治的视角

冷战后的美国,凭借其独一无二的超强实力,大胆颠覆之前麦金德的“大陆中心说”,并借助马汉、斯皮克曼的地缘政治学说为其独霸世界谋篇布局,分别把亚欧大陆的俄罗斯、中国、欧盟和印度等新兴大国或组织假想为潜在威胁,并想方设法在全球范围内寻求盟友以遏制这些国家。美国独霸世界的合纵连横战略对当今国际社会产生了重要影响,今天的巴以冲突、乌克兰危机、“伊斯兰国”恐怖主义的大肆蔓延以及日本安保法案的通过,都与美国独霸世界的合纵连横战略有直接的关系。     

Parental military service and adolescent well‐being: mental health,social connections and coping among youth in the USA

The association between parental military work factors and adolescent's well‐being was examined. Data were collected from 1036 military youth. Using a within‐group design, we examined adolescent's well‐being related to parental absence, school and neighbourhood transitions, paygrade/rank and participation in military‐sponsored activities, and differentiated outcomes by sex and age. Two parental work factors primarily influenced adolescent's well‐being, parental paygrade/rank and engagement in military‐sponsored activities. Parental paygrade/rank was the only factor uniformly related to poorer well‐being, and this variable likely represents a more complex set of family circumstances. Engaging in military‐sponsored activities served as a resource and was related to enhanced well‐being. Individual‐level differences and implications for social workers are discussed.     

Coaching in den USA

Coaching in the USA. Executive Coaching has in the USA emerged as a major developmental tool in many organizations. At the same time the domain of what coaching compasses are now so diverse that it is more difficult to put boundaries around the construct. In the current coaching literature, coaching is something of a “black box”. We know it can work but often we do not know why it works. Without empirical research and especially a stronger theoretical foundation, coaching runs the risk of failing into a passing trend.
