Getting off on the right foot: Subjective value versus economic value in predicting longitudinal job outcomes from job offer negotiations.

Although negotiation experiences can affect a negotiator's ensuing attitudes and behavior, little is known about their long-term consequences. Using a longitudinal survey design, the authors tested the degree to which economic and subjective value achieved in job offer negotiations predicts employees' subsequent job attitudes and intentions concerning turnover. Results indicate that subjective value predicts greater compensation satisfaction and job satisfaction and lower turnover intention measured 1 year later. Surprisingly, the economic outcomes that negotiators achieved had no apparent effects on these factors. Implications, limitations, and future directions are discussed.

What do people value when they negotiate? Mapping the domain of subjective value in negotiation.

Four studies support the development and validation of a framework for understanding the range of social psychological outcomes valued subjectively as consequences of negotiations. Study 1 inductively elicited and coded elements of subjective value among students, community members, and practitioners, revealing 20 categories that theorists in Study 2 sorted into 4 underlying subconstructs: Feelings About the Instrumental Outcome, Feelings About the Self, Feelings About the Negotiation Process, and Feelings About the Relationship. Study 3 proposed a new Subjective Value Inventory (SVI) and confirmed its 4-factor structure. Study 4 presents convergent, discriminant, and predictive validity data for the SVI. Indeed, subjective value was a better predictor than economic outcomes of future negotiation decisions. Results suggest the SVI is a promising tool to systematize and encourage research on subjective outcomes of negotiation. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

A prospective study of dietary calcium and other nutrients and the risk of symptomatic kidney stones

BACKGROUND: A high dietary calcium intake is strongly suspected of increasing the risk of kidney stones. However, a high intake of calcium can reduce the urinary excretion of oxalate, which is thought to lower the risk. The concept that a higher dietary calcium intake increases the risk of kidney stones therefore requires examination. METHODS: We conducted a prospective study of the relation between dietary calcium intake and the risk of symptomatic kidney stones in a cohort of 45,619 men, 40 to 75 years of age, who had no history of kidney stones. Dietary calcium was measured by means of a semiquantitative food-frequency questionnaire in 1986. During four years of follow-up, 505 cases of kidney stones were documented. RESULTS: After adjustment for age, dietary calcium intake was inversely associated with the risk of kidney stones; the relative risk of kidney stones for men in the highest as compared with the lowest quintile group for calcium intake was 0.56 (95 percent confidence interval, 0.43 to 0.73; P for trend, < 0.001). This reduction in risk decreased only slightly (relative risk, 0.66; 95 percent confidence interval, 0.49 to 0.90) after further adjustment for other potential risk factors, including alcohol consumption and dietary intake of animal protein, potassium, and fluid. Intake of animal protein was directly associated with the risk of stone formation (relative risk for men with the highest intake as compared with those with the lowest, 1.33; 95 percent confidence interval, 1.00 to 1.77); potassium intake (relative risk, 0.49; 95 percent confidence interval, 0.35 to 0.68) and fluid intake (relative risk, 0.71; 95 percent confidence interval, 0.52 to 0.97) were inversely related to the risk of kidney stones. CONCLUSIONS: A high dietary calcium intake decreases the risk of symptomatic kidney stones.     

Thin slices of negotiation: Predicting outcomes from conversational dynamics within the first 5 minutes.

In this research the authors examined whether conversational dynamics occurring within the first 5 minutes of a negotiation can predict negotiated outcomes. In a simulated employment negotiation, microcoding conducted by a computer showed that activity level, conversational engagement, prosodic emphasis, and vocal mirroring predicted 30% of the variance in individual outcomes. The conversational dynamics associated with success among high-status parties were different from those associated with success among low-status parties. Results are interpreted in light of theory and research exploring the predictive power of "thin slices" of behavior (N. Ambady & R. Rosenthal, 1992). Implications include the development of new technology to diagnose and improve negotiation processes. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Dietary calcium, dietary protein, and kidney stone formation

Kidney stone disease is common and is a major cause of morbidity involving the urinary tract. Rising incidence rates of calcium oxalate stone disease, the most common type of kidney stone, have focused attention on dietary habits and their potential role in the development of nephrolithiasis. Traditionally, calcium restriction had been recommended to reduce the likelihood of calcium stone formation, but recent evidence suggests that dietary calcium restriction may actually increase the risk. Observational and experimental data suggest that restriction of animal protein may lower the risk of stone formation, but a randomized trial did not confirm this finding. Dietary modification may play an important role in reducing the likelihood of stone recurrence. Notably, dietary calcium restriction should be avoided in patients who have had a calcium oxalate kidney stone.     

Epidemiology of interstitial cystitis: a population based study

Mycobacterium sp. strain CH1 was isolated from polycyclic aromatic hydrocarbon (PAH)-contaminated freshwater sediments and identified by analysis of 16S rDNA sequences. Strain CH1 was capable of mineralizing three- and four-ring PAHs including phenanthrene, pyrene, and fluoranthene. In addition, strain CH1 could utilize phenanthrene or pyrene as a sole carbon and energy source. A lag phase of at least 3 days was observed during pyrene mineralization. This lag phase decreased to less than 1 day when strain CH1 was grown in the presence of phenanthrene or fluoranthene. Strain CH1 also was capable of using a wide range of alkanes as sole carbon and energy sources. No DNA hybridization was detected with the nahAc gene probe, indicating that enzymes involved in PAH metabolism are not related to the well-characterized naphthalene dioxygenase gene. DNA hybridization was not detected when the alkB gene from Pseudomonas oleovorans was used under high-stringency conditions. However, there was slight but detectable hybridization under low-stringency conditions. This suggests a distant relationship between genes involved in alkane oxidation.     

Negotiators who give too much: Unmitigated communion, relational anxieties, and economic costs in distributive and integrative bargaining.

A series of studies found that the personality dimension of unmitigated communion (H. L. Fritz & V. S. Helgeson, 1998) leads negotiators to make concessions to avoid straining relationships. Results indicate that even within the population of successful business executives, this dimension of relational anxiety can be identified distinctly from more general relational orientations, such as agreeableness, and that it distinctly predicts accommodating tendencies in everyday conflicts. In economic games, unmitigated communion predicts giving in contexts in which the relational norm of reciprocity applies, but not in contexts tapping instrumental or altruistic motives for cooperation. In distributive negotiations, the effect of unmitigated communion in lowering a negotiator's outcome is mediated by prenegotiation anxieties about relational strain and plans to make large concessions if needed to avoid impasse (lower reservation points). In integrative negotiations, high unmitigated communion on both sides of the negotiation dyad results in relational accommodation, evidenced by decreased success in maximizing economic joint gain but increased subjective satisfaction with the relationship.

Prospective study of beverage use and the risk of kidney stones

We have analysed the replication of the heterochromatic megachromosome that was formed de novo by a large-scale amplification process initiated in the centromeric region of mouse chromosome 7. The megachromosome is organized into amplicons approximately 30 Mb in size, and each amplicon consists of two large inverted repeats delimited by a primary replication initiation site. Our results suggest that these segments represent a higher order replication unit (megareplicon) of the centromeric region of mouse chromosomes. Analysis of the replication of the megareplicons indicates that the pericentric heterochromatin and the centromere of mouse chromosomes begin to replicate early, and that their replication continues through approximately three-quarters of the S-phase. We suggest that a replication-directed mechanism may account for the initiation of large-scale amplification in the centromeric regions of mouse chromosomes, and may also explain the formation of new, stable chromosome segments and chromosomes.
