The planning of a department store

A town or village attracts people from its hinterland to purchase goods by virtue of the amount and variety of goods on offer. Similarly, a department store attracts customers away from cempetitors by means of displays, staff expertise, stock holdings and numerous other parameters. The store is generally free to manipulate these parameters subject to certain restrictions; the manipulation will have a direct affect on the ultimate profitability of the store. This paper describes some current research that is being carried out in conjunction with a department store group. The ultimate aim is to link the corporate planning of the group and each store to detailed socioeconomic data describing the population. Some aspects of the problem have been investigated in depth, some are currently being discussed and some have not been considered at all as yet. The latest position will be reported and hopefully some feedback will be engendered.     

Sensitivity and Uncertainty Studies of the CRAC2 Computer Code

We have studied the sensitivity of health impacts from nuclear reactor accidents, as predicted by the CRAC2 computer code, to the following sources of uncertainty: (1) the model for plume rise, (2) the model for wet deposition, (3) the meteorological bin-sampling procedure for selecting weather sequences with rain, (4) the dose conversion factors for inhalation as affected by uncertainties in the particle size of the carrier aerosol and the clearance rates of radionuclides from the respiratory tract, (5) the weathering half-time for external ground-surface exposure, and (6) the transfer coefficients for terrestrial foodchain pathways. Predicted health impacts usually showed little sensitivity to use of an alternative plume-rise model or a modified rain-bin structure in bin-sampling. Health impacts often were quite sensitive to use of an alternative wet-deposition model in single-trial runs with rain during plume passage, but were less sensitive to the model in bin-sampling runs. Uncertainties in the inhalation dose conversion factors had important effects on early injuries in single-trial runs. Latent cancer fatalities were moderately sensitive to uncertainties in the weathering half-time for ground-surface exposure, but showed little sensitivity to the transfer coefficients for terrestrial foodchain pathways. Sensitivities of CRAC2 predictions to uncertainties in the models and parameters also depended on the magnitude of the source term, and some of the effects on early health effects were comparable to those that were due only to selection of different sets of weather sequences in bin-sampling.     

Decomposing culture: an analysis of gender,language, and labor supply in the household

Despite broad progress in closing many dimensions of the gender gap around the globe, recent research has shown that traditional gender roles can still exert a large influence on female labor force participation, even in developed economies. This paper empirically analyzes the role of culture in determining the labor market engagement of women within the context of collective models of household decision making. In particular, we use the epidemiological approach to study the relationship between gender in language and labor market participation among married female immigrants to the U.S. We show that the presence of gender in language can act as a marker for culturally acquired gender roles and that these roles are important determinants of household labor allocations. Female immigrants who speak a language with sex-based grammatical rules exhibit lower labor force participation, hours worked, and weeks worked. Our strategy of isolating one component of culture reveals that roughly two thirds of this relationship can be explained by correlated cultural factors, including the role of bargaining power in the household, and the impact of ethnic enclaves and that at most one third is potentially explained by language having a causal impact.     

Colleges’ and universities’ use of Twitter: A content analysis

This study explored how colleges and universities are employing Twitter, a popular micro-blogging tool. Using Kent and Taylor's principles of dialogic communication, a content analysis was performed on individual tweets (n = 1130) from 113 colleges and universities. Tweets were coded for whether or not they met each principle of dialogical communication and why. It was found that institutions are not employing Twitter in a dialogic way and they are, instead, employing it primarily as an institutional news feed to a general audience. The implications of this finding are discussed.     

MARRIAGE MARKET MATCHING AND CONSPICUOUS CONSUMPTION IN CHINA

Visible expenditures which convey higher socioeconomic status may help individuals differentiate themselves in the marriage market when there is competition for partners and imperfect information. We examine a unique dataset of automobile purchasers in China to investigate the extent to which skewed sex ratios influence expenditure decisions for this highly visible commodity. Using a triple difference approach, we show that unmarried male consumers who face an unfavorable sex ratio purchase more expensive, luxury vehicles than their married peers. Lower income borrowers and those residing in regions with the worst sex ratios exhibit the largest relative degree of conspicuous consumption. In addition to the direct cost of consumption signaling, we demonstrate that this behavior generates negative externalities in the form of lower average fuel economy and higher average vehicle weight. As it has worsened sex ratios, status competition and the associated negative repercussions we identify represent unintended consequences of China's one child policy. (JEL O12, E21, J12)     

WITHIN U.S. TRADE AND THE LONG SHADOW OF THE AMERICAN SECESSION

Using data from U.S. commodity flow survey, we show that the historical Union–Confederacy border lowers contemporaneous trade between U.S. states by about 13%. The finding is robust over econometric models, survey waves, or aggregation levels. Including contemporaneous controls, such as network or institutional variables, lowers the estimate only slightly. Historical variables, such as slavery, do not explain the effect. Adding U.S. states unaffected by the Civil War, we argue that the friction is not merely reflecting unmeasured North–South differences. Finally, the border effect is larger for differentiated than for homogeneous goods, stressing the potential role for cultural factors and trust. (JEL F15, N72, N92, Z10)     

Professionals' attitudes about victims of child sexual abuse: implications for collaborative child protection teams

In responding to victims of child sexual abuse, considerable attention has been given to multidisciplinary collaborative response teams. Recent evidence, however, suggests that team members may be divided by differences in attitudes towards victims and offenders and about the causes and consequences of abuse. This paper draws on a larger study of the various professionals who make up one child abuse response system in Newfoundland, Canada. In particular, the paper focuses on social workers, teachers and the police, and their views about the characteristics and credibility of sexual abuse victims, and the extent to which they attribute to the victim some responsibility for the abuse. Data for the study were collected in two stages: key informant interviews; and a survey of social workers, teachers and police. The analysis includes an interpretation of the role of gender, professional group membership and experience with cases. The most striking finding is the extent to which the child's age and behaviour appears to influence differentially attitudes about the victims' credibility. These differences complicate multidisciplinary collaborative initiatives since it would appear that those with the least real case experience, and the least knowledge about the relationship between abuse and behaviour, are the ones most likely to be the first point of contact for reports or disclosures.     

Storying transition-to-work for/and youth on the autism spectrum in the United States: a critical construct synthesis of academic literature

We explored how academic literature constructs the ‘worker with autism.’ Drawing on a systematic review of transition to work for youth with disabilities, we analyzed how 17 articles constructed ‘autism,’ ‘work,’ and the ‘worker with autism.’ We identified two argumentative approaches: the intervention story and the complex story. Intervention stories centered autism as a problem in need of treatment and work as a simple, positive endeavor. Complex stories offered various and more positive accounts of autism alongside broader notions of work. We recommend that academics experiment with writing which expands work (and career) possibilities for youth situated on the autism spectrum.
