Leadership styles,mentoring functions received,and job‐related stress: a conceptual model and preliminary study

This research examined linkages between mentor leadership behaviors (laissez‐faire, transactional contingent reward, and transformational), protégé perception of mentoring functions received (career development and psychosocial support) and job‐related stress of 204 mentor–protégé dyads. Results of Partial Least Squares analysis revealed that mentor transformational behavior was more positively related to mentoring functions received than transactional contingent reward behavior, while mentor laissez‐faire behavior was negatively related to mentoring functions received. Both mentor transformational behavior and mentoring functions received were negatively related to protégé job‐related stress. The relationship between mentor transformational behavior and protégé job‐related stress was moderated by the level of mentoring functions received. Results are discussed as they relate to researchers and practitioners who are becoming interested in finding ways to develop organizational members and allay job‐related stress.

Prioritization of Ecosystem Services Research: Tampa Bay Demonstration Project

The Tampa Bay Ecosystem Services Demonstration Project (TBESDP) is part of the U.S. Environmental Protection Agency’s Ecosystem Services Research Program. The principal objectives of TBESDP are to (1) quantify the ecosystem services of the Tampa Bay watershed, (2) determine the value of ecosystem services to society, (3) predict the supply of ecosystem services under future scenarios of population growth and climate change, and (4) apply this knowledge through models and tools that will support the best informed environmental decisions possible. The scope and complexity of this project required intensive effort to establish which services can be quantified by applying existing models, data, and scientific literature and which services will require supporting research. Research priorities were assessed by: (1) developing and refining conceptual models of major ecosystems in the Tampa Bay region, (2) gathering input from stakeholders about the relative importance and values of various ecosystem services, (3) preparing and reviewing a bibliometric analysis of the volume of scientific literature relevant to the ecosystems and services of interest, and (4) evaluating an integrated analysis of importance, value, and availability of scientific information. This analysis led us to focus on two research priorities, seagrass-habitat functions as support for fishery production, and wetlands as regulators of water quality.     

The nomological and predictive validity of time urgency

The present study developed a nomological network that theoretically linked time urgency to related variables. To test the proposed relationships, time urgency, achievement strivings (AS), and impatience/irritability (II) were utilized as predictors of health and performance 18 months later. Multivariate canonical correlation analyses provided support for a complex nomological network among the predictors and the outcome measures. Redundancy coefficients and a rotated structure matrix were employed to identify two significant dimensions, labeled crammers and organizers, that linked the predictors with the outcome measures. The results also indicated that the time urgency subcomponents were differentially related to several health outcomes. These findings provide further validity evidence for the time urgency construct, and they suggest that time urgency variables should be considered as important predictors of both health and performance outcomes. Directions for future research on time urgency are discussed. © 1998 John Wiley & Sons, Ltd.     

Work-related commitment and job performance: it's also the nature of the performance that counts

This study tested the proposition that relationships among the various types of work-related commitment and job performance are affected by both the form of commitment and the facet of performance under consideration. Results provided some support for this view. As hypothesized, job involvement was related only to performance tied to intrinsically rewarding elements of work, and career commitment was positively related to overall performance effectiveness. Unexpectedly, however, organizational commitment (both affective and continuance) was unrelated to job performance. The discussion is centered on practical implications of these findings and on directions for future research. © 1998 John Wiley & Sons, Ltd.     

Perceived support in a dual organizational environment: Union participation in a university setting

There is extensive research on employee attitudes regarding employers and unions, but these studies have underemphasized social and affective forces. Most studies also examine attitudes toward either the union or the employer without considering how these attitudes might relate to one another. The present study of faculty (N = 306) at a large public research university demonstrated that perceptions of union support were positively related to union participation and perceptions of administration support were negatively related to union participation. Subjective norms and general union attitudes were related to perceptions of union support, and subjective norms were related to perceived organizational support. Taken together, an individual's participation in a union recognition effort depends not only on union instrumentality, but also upon social relationships with the union and administration.

Total quality management and performance appraisal: an experimental study of process versus results and group versus individual approaches

This study investigated the effect of a process versus a results focus as well as a group versus individual‐based approach to performance appraisals. Four experimental conditions were investigated, with dependent variables of appraisal satisfaction, perceived accuracy of the performance appraisal, expectations of performance improvement, and actual performance. The results showed that a process focus appraisal had a more positive impact than an exclusively results‐oriented appraisal on ratee appraisal satisfaction, perceived appraisal accuracy, and expectations of performance improvement. Subjects receiving process appraisal feedback also showed a greater improvement in actual performance during a subsequent trial compared to subjects that did not receive process feedback. No differences were found between the group‐ and the individual‐based performance appraisal conditions. Implications of these findings for appraisal processes in general, and total quality initiatives in particular, are discussed. Copyright © 1999 John Wiley & Sons, Ltd.

Identification of a floral-derived kairomone for currant clearwing, <Emphasis Type="Italic">Synanthedon tipuliformis</Emphasis>

The currant clearwing Synanthedon tipuliformis (Clerck) (Sesiidae) is a worldwide pest of black currants, Ribes nigrum. This moth has been observed to feed on nectar of inflorescences of Canada thistles, Cirsium arvense (L.) Scop. This work was undertaken to identify floral compound(s) produced by Canada thistles inflorescences that mediate the response of the currant clearwing. Floral volatiles were collected during the day and analysed by coupled gas chromatography/electroantennographic detection (GC/EAD) and gas chromatography/mass spectrometry (GC/MS). Three compounds consistently elicited EAD response from moth antennae and were identified by GC/MS as phenylacetaldehyde, methyl salicylate and dimethyl salicylate. When the compounds were tested individually or in various combinations in field trapping experiments, a 3-component blend attracted the largest number of female and male currant clearwings. Subsequent field trapping experiments were conducted to determine the optimal attraction dose for the ternary blend using three loadings of 1, 10 and 100 mg loaded into a polyethylene sachet. The highest catches were in traps baited with the 100 mg loading. In all trials, males and mated females were caught in significant numbers, while very low numbers of virgin females were found in the traps. In recent years the efficacy of mating disruption against currant clearwing has been reported as declining. The new kairomone blend identified in this study can be used with the sex pheromone to provide an effective control option for this important pest.
