Resistance and Cooperation: A Response to Conflict Over Job Performance

Research literature on job performance from bothmanagement oriented and industrial relations/sociologyof work models is synthesized to produce a morecomprehensive understanding of how supervisors manage employee performance problems. Two assumptionsare derived from the synthesis: (1) employees are activein accepting and resisting definitions of performanceissues made by supervisor; (2) informal interactions regarding the interpretation of performanceissues are pivotal in understanding how performanceproblems are resolved. In a study of university librarysupervisors we focus on the informal exchanges and characterize them as negotiations over thedefinition of job performance. We report results from aqualitative study of supervisors' interactions withemployees identified as having performance problems. Three types of interactions in informalnegotiations are found. We label the supervisors'interpretations of their interactions with employees asconformist, confrontational, or rebellious, designating how supervisors enact their role as agents ofthe organization.     

A randomized controlled trial of a 5-year marriage checkup booster session for a subsample of responder couples

This study examined maintenance and booster effects of a brief couple intervention, the Marriage Checkup (MC), across 5 years. A subsample of 63 couples who benefitted from two previous MCs (responder couples), were randomly assigned to a third MC or control. Before randomization (at 4-years-9-months), the responder sample had maintained small to medium effects on two measures of relationship functioning. After randomization, we found no significant between-group effects. Yet, within-group analyses revealed that while control couples showed flat trajectories in all outcomes after the 4-year-9-months baseline, couples receiving a third MC (at Year 5) reported small to medium improvements in three measures of relationship functioning and maintained follow-up effect in one measure. Findings indicate that couples who initially improved from the MC can maintain some of their improvements over long periods. The potential of boosting such improvements with recurrent MCs is a relevant target for further investigation in larger samples.     

Indian agricultural policy: An applied general equilibrium model

A ten-sector, sequential applied general equilibrium model is formulated, estimated, and stimulated for analyzing agricultural policy choices for India until year 2000. Ten groups of consumers (five of them rural), each with its own preferences and claims on output are recognized in the model, the groups distinguished by the range of their per capita household (real) consumption expenditure. The simulations compare: four policies with respect to the compulsory purchase and subsidized distribution to consumers of a limited amount of foodgrains and four foreign trade and aid scenarios. Procuring and freely distributing 100 kgs of grain per capita per year and financing the cost through additional taxation improves income distribution with no reduction in growth. On the other hand, the same distributional policy financed by reducing investment has a negative impact on growth.     

THE GENERALIZED INVERSE,WITH NONLINEAR REGRESSION AND MATHEMATICAL PROGRAMMING APPLICATIONS

This paper is a tutorial exposition on the generalized inverse of a matrix with typical applications to regression analysis and mathematical programming. The exposition contains examples exhibiting geometrical motivation and related facts useful in application of the generalized inverse. Some proofs are given to indicate a few of the theoretical aspects of the generalized inverse.

A Web-based review of sexual and reproductive health services available at colleges and universities in Georgia

Objective: Although two-thirds of graduating high school seniors attend college or university in the U.S., there is a paucity of national or state specific research regarding SRH services available on or near college and university campuses.

Methods: A review of websites for all colleges and universities in Georgia was conducted to evaluate sexual health services available on campuses and evidence of referral to community providers.

Results: Of 96 colleges in Georgia, 44 had campus-located health centers, with only 3 at two-year colleges. Overall SRH service provision was low, with great variation between colleges. Distances between colleges and Title X clinics ranged from 0.33 to 35.45 miles.

Conclusions: Many students lack access to campus health centers, and information on college websites regarding SRH service availability and referrals differs dramatically between campuses. In the absence of robust campus-located services, schools should highlight where students can obtain comprehensive SRH care in the community.
