Recruitment, Job Choice, and Post-Hire Consequences: A Call For New Research Directions

Abstract: Excerpt] "Technology in employee selection is more highly developed than in recruiting or placement; therefore, the major emphasis is on selection Recruiting or placement are not less important processes; to the contrary, they probably are more vital and more profitable to the organization. An organization's success in recruiting defines the applicant population with which it will work; selection is more pleasant, if not easier, when any restriction of range or skewness of distribution is attributable to an overabundance of well-qualified applicants... Unfortunately,the contributions and confusions of the literature, the central social pressures, and the facts of contemporary practice conspire to place the emphasis on selection" (pp. 777779)

The Discipline of Rankings: Tight Coupling and Organizational Change.

Abstract: This article demonstrates the value of Foucault's conception of discipline for understanding organizational responses to rankings. Using a case study of law schools, we explain why rankings have pe...

The Effect of SOX Internal Control Deficiencies and Their Remediation on Accrual Quality

Abstract: This paper investigates the effect of internal control deficiencies and their remediation on accrual quality. We first document that firms reporting internal control deficiencies have lower quality accruals as measured by accrual noise and absolute abnormal accruals relative to firms not reporting internal control problems. Second, we find that firms that report internal control deficiencies have significantly larger positive and larger negative abnormal accruals relative to control firms. This finding suggests internal control weaknesses are more likely to lead to unintentional errors that add noise to accruals than intentional misstatements that bias earnings upward. Third, we document that firms whose auditors confirm remediation of previously reported internal control deficiencies exhibit an increase in accrual quality relative to firms that do not remediate their control problems. Finally, we find firms that receive different internal control audit opinions in successive years exhibit changes in accrual quality consistent with changes in internal control quality. Collectively, our cross-sectional and inter-temporal change tests provide strong evidence that the quality of internal control affects the quality of accruals.

Vitamin D intake is inversely associated with rheumatoid arthritis: results from the Iowa Women's Health Study

Abstract: Objective Vitamin D is a potent regulator of calcium homeostasis and may have immunomodulatory effects. The influence of vitamin D on human autoimmune disease has not been well defined. The purpose of this study was to evaluate the association of dietary and supplemental vitamin D intake with rheumatoid arthritis (RA) incidence. Methods We analyzed data from a prospective cohort study of 29,368 women of ages 55-69 years without a history of RA at study baseline in 1986. Diet was ascertained using a self-administered, 127-item validated food frequency questionnaire that included supplemental vitamin D use. Risk ratios (RRs) and 95% confidence intervals (95% CIs) were estimated using Cox proportional hazards regression, adjusting for potential confounders. Results Through 11 years of followup, 152 cases of RA were validated against medical records. Greater intake (highest versus lowest tertile) of vitamin D was inversely associated with risk of RA (RR 0.67, 95% CI 0.44-1.00, P for trend = 0.05). Inverse associations were apparent for both dietary (RR 0.72, 95% CI 0.46-1.14, P for trend = 0.16) and supplemental (RR 0.66, 95% CI 0.43-1.00, P for trend = 0.03) vitamin D. No individual food item high in vitamin D content and/or calcium was strongly associated with RA risk, but a composite measure of milk products was suggestive of an inverse association with risk of RA (RR 0.66, 95% CI 0.42-1.01, P for trend = 0.06). Conclusion Greater intake of vitamin D may be associated with a lower risk of RA in older women, although this finding is hypothesis generating.
