Bimodal issues,the median voter model,Legislator's ideology,and abortion

The median voter model is widely used in the public choice literature to explain legislator's behavior. According to the model, if voter preferences are unimodal, a vote-maximizing legislator should mirror the position of the median voter. However, the median voter model has not been tested on bimodal issues. This paper fills this critical void by empirically testing the applicability of the median voter model on an issue which clearly meets the criteria for being bimodal: abortion. Using a variety of attitudinal measures from large sample public opinion polls and constituency demographics, this study finds that Senate voting on the 1994 Freedom of Abortion Access bill was highly related to the senator's personal characteristics—especially ideology—and not to constituent opinion or demographics.     

Contextual marketing--the real business of the Internet

The painful truth is that the Internet has been a letdown for most companies--largely because the dominant model for Internet commerce, the destination Web site, doesn't suit the needs of those companies or their customers. Most consumer product companies don't provide enough value or dynamic information to induce customers to make the repeat visits--and disclose the detailed information--that make such sites profitable. In this article, David Kenny and John F. Marshall suggest that companies discard the notion that a Web site equals an Internet strategy. Instead of trying to create destinations that people will come to, companies need to use the power and reach of the Internet to deliver tailored messages and information to customers. Companies have to become what the authors call "contextual marketers." Delivering the most relevant information possible to consumers in the most timely manner possible will become feasible, the authors say, as access moves beyond the PC to shopping malls, retail stores, airports, bus stations, and even cars. The authors describe how the ubiquitous Internet will hasten the demise of the destination Web site--and open up scads of opportunities to reach customers through marketing "mobilemediaries," such as smart cards, e-wallets, and bar code scanners. The companies that master the complexity of the ubiquitous Internet will gain significant advantages: they'll gain greater intimacy with customers and target market segments more efficiently. The ones that don't will be dismissed as nuisances, the authors conclude. They suggest ways to become welcome additions--not unwelcome intrusions--to customers' lives.

Meanings of Food among Polish and American Young Women

Food carries different meanings across cultures and times. This study aimed to explore the meanings of food among young women in Poland and the United States using a qualitative approach. The findings show that, in both countries, women associate food with health, pleasure, and socializing, but overall Polish women are less emotional about food. More specifically, in the United States, women associate food with love, their identities, and have more conflictual feelings about food, whereas in Poland women associate food with creativity. The study discusses marketing implications of the results.     

Time series momentum and moving average trading rules

We compare and contrast time series momentum (TSMOM) and moving average (MA) trading rules so as to better understand the sources of their profitability. These rules are closely related; however, there are important differences. TSMOM signals occur at points that coincide with a MA direction change, whereas MA buy (sell) signals only require price to move above (below) a MA. Our empirical results show MA rules frequently give earlier signals leading to meaningful return gains. Both rules perform best outside of large stock series which may explain the puzzle of their popularity with investors, yet lack of supportive evidence in academic studies.     

Indigenous livelihoods, slash-and-burn agriculture, and carbon stocks in Eastern Panama

Improved crop–fallow systems in the humid tropics can simultaneously sequester atmospheric carbon emissions and contribute to sustainable livelihoods of rural populations. A study with an indigenous community in eastern Panama revealed a considerable biophysical potential for carbon offsets in small-scale slash-and-burn agriculture through longer fallow periods, improved fallow management, secondary forest development, and agricultural intensification. Based on soil and biomass carbon measurements, estimated annual sequestration rates amount to 0.3−3.7 t C ha^− 1 yr^− 1. Despite such potential, the economic benefits of initiatives aimed at sequestration of carbon in the community are likely to be rather unequally distributed within the community. Heterogeneity in livelihood strategies and uneven asset endowments among households – factors often overlooked in the ongoing carbon and sustainable development debate – are expected to strongly affect household participation. Indeed, only the better-endowed households that have also managed to diversify into more lucrative farm and non-farm activities are likely to be able to participate in and thus benefit from improved crop–fallow systems that capture carbon. Economic, ethical, institutional, and technical concerns need to be taken into account when designing community carbon management and investment plans.     

Tourism development and behavioural changes: evidences from Ratanakiri province,Kingdom of Cambodia

This research paper presents the findings of a research undertaken in Ratanakiri province, Kingdom of Cambodia (Under the RETA 6190 ADB TA project on ‘Preventing the Trafficking of Women and Children and Promoting Safe Migration in the GMS’), with the aim to evaluate the impact of an airport rehabilitation project. It highlights the role that infrastructure development, with a focus on tourism-related projects, can play in a remote rural area and its consequences on local population, especially ethnic minorities. For remote areas, tourism is considered as an accelerating influence on globalisation and in-migration, which, in turn, are seen as the main factors affecting remote local communities to modify behaviours changing from valuing utility to valuing exchange. The rapidity of these cultural changes increase rural depopulation and the vulnerability of human beings to a range of negative situational factors, including loss of land, erosion of community structures and coping mechanisms, and as well as exploitative practices such as debt bondage, prostitution and human trafficking.
