The Effect of Negotiation Practices on the Relationship between Suppliers and Customers

This article examines the effects of negotiation practices, such as coercion and contract formality, on how suppliers and customers perceived the resulting business relationship. We conducted a purchasing negotiation simulation with students in a classroom setting in which participants competed for resources in a mock supply-chain context. The participants were surveyed at key stages of the ongoing negotiation in order to measure their behaviors as a customer–supplier relationship developed. The data were used to test several hypotheses developed from the marketing and purchasing literature. The hypotheses were analyzed using structural equation modeling.
Results demonstrated that the use of coercive techniques by negotiators during negotiation had a negative effect on satisfaction. In addition, the findings showed that, as expected, negotiators entering a negotiation with a cooperative orientation would tend to avoid the use of coercive practices during negotiation. The cooperative orientation also exhibited an unexpected positive effect on the formalization of the design of the contract between the parties. This study contributes to the current knowledge base focusing on the creation of agreements between companies and will, we hope, encourage the integration of suppliers and customers in an operating context within a supply-chain setting.     

Federal policy mandating safer cigarettes: a hypothetical simulation of the anticipated population health gains or losses.

If manufacturing a safer cigarette is technically possible--an open question--then mandating that tobacco manufacturers improve the safety of cigarettes would likely have both positive and negative implications for the nation's health. On the one hand, removing toxins may reduce the incidence of smoking-related diseases and premature mortality in smokers. On the other hand, smokers might be less inclined to quit, those who have quit might resume the habit, and youth who have never smoked will have one less reason to avoid tobacco use. To assess the expected population health impacts of a legislative or regulatory mandate, we created the Tobacco Policy Model, a system dynamics computer simulation model. The model relies on secondary data and simulates the U.S. population over time spans as long as 50 years. Our simulation results reveal that even if requiring cigarettes to be safer makes smoking more attractive and increases tobacco use, a net gain in population health is still possible.     

Perceptions of control,depressive symptomatology,and self-esteem of women in transition from abusive relationships

The relation between women’s histories of experiencing violence and current psychological health were examined. Locus of control, feelings of personal power, depressive symptomatology, self-esteem, and judgments of control over a contingently responsive computer display were investigated in groups of 21 abused women and 18 comparison women. Within the sample of abused women, relationships between severity of abuse and the psychological variables were also examined. The group of abused women had lower beliefs in self-efficacy, were more depressed, and had lower self-esteem than the comparison women. There were no differences found, however, between the two groups in perceptions of control on the computer task. Severity of physical abuse among the abused women was positively correlated with depression scores. Verbal abuse was found to contribute significantly to many of the between-group differences. Empirical evidence of the positive impact of transition house residence on the abused women’s mental health was also presented. The importance of future research into both the differential effects of verbal and physical abuse on women and the role of the transition house in empowering abused women were discussed.     

Interrogating genomic diversity of E. coli O157:H7 using DNA tiling arrays

Here, we describe a novel microarray-based approach for investigating the genomic diversity of Escherichia coli O157:H7 in a semi-high throughput manner using a high density, oligonucleotide-based microarray. This microarray, designed to detect polymorphisms at each of 60,000 base-pair (bp) positions within an E. coli genome, is composed of overlapping 29-mer oligonucleotides specific for 60 equally spaced, 1000-bp loci of the E. coli O157:H7 strain EDL933 chromosome. By use of a novel 12-well microarray that permitted the simultaneous investigation of 12 strains, the genomes of 44 individual isolates of E. coli O157:H7 were interrogated. These analyses revealed more than 150 single nucleotide polymorphisms (SNPs) and several deletions and amplifications in the test strains. Pyrosequencing was used to confirm the usefulness of the novel SNPs by determining their allelic frequency among a collection of diverse isolates of E. coli O157:H7. The tiling DNA microarray system would be useful for the tracking and identification of individual strains of E. coli O157:H7 needed for forensic investigations.     

The Olympics: 64 years on

In just over a month's time London will be the centre of international focus as athletes from over 200 countries arrive for the Olympic Games. The last Olympic Games held in London was in 1948 – in the same month the National Health Service (NHS) was established. It is a tragic coincidence that the Olympics returns to London in the same year as the Health and Social Care Act was passed, legislation the chairman of the British Medical Association described as likely to be ‘irreversibly damaging to the NHS as a public service, converting it into a competitive marketplace that will widen health inequalities and be detrimental to patient care’ (Buckman, 2012).     

Housing Upkeep and Public Good Provision in Residential Neighborhoods

Neighborhood condition is a public good in part provided by neighborhood residents’ private property maintenance. Considering neighborhood condition as an impure public good provides a theoretical basis for understanding how the level of neighborhood quality may affect residents’ home maintenance decisions. Empirical results in a low-income neighborhood, where formulating public policy to improve neighborhoods is of significant concern, indicate a positive substitution effect. When neighborhoods improve, residents respond by increasing exterior home upkeep. This result is robust to both changes in the neighborhood condition generated by other neighbors’ increase in maintenance and exogenous public investment in the neighborhood.
