Preemergence Herbicides

A field and greenhouse study was conducted to determine the relative effectiveness of preemergence herbicides applied at low volume (9.35 to 37.4 L/ha) and conventional volume (187 L/ha). In the field study 11 preemergence herbicides were applied to plots seeded with seven weed species. Five herbicides were used in the greenhouse study each applied at five rates and two volumes. Both field and greenhouse results indicated that water soluble materials and emulsifiable concentrates which need not be incorporated can be applied at low volume with results comparable to conventional volume application. Field results suggested wettable powders can be applied low volume with success; however, greenhouse results indicated that with present equipment and technique wettable powders are not well suited for low volume application. Incorporated materials were included only in the field study and gave irregular results.

Achievement Motive

Abstract. Explicit motives are well-studied in the field of personality and motivation psychology. However, the statistical overlap of different explicit motive measures is only moderate. As a consequence, the Unified Motive Scales (UMS; Schönbrodt & Gerstenberg, 2012 ) were developed to improve the measurement of explicit motives. The present longitudinal field study examined the predictive validity of the UMS achievement motive subscale. Applicants of a police department ( n = 168, Mage = 25.11, 53 females and 115 males) completed the UMS and their performance in the selection process was assessed. As expected, UMS achievement predicted success in the selection process. The findings provide first evidence for the predictive validity of UMS achievement in an applied setting.

Positive Effect

Abstract. This study uses implicit voice theory to examine the influence of employees’ critical thinking and leaders’ inspirational motivation on employees’ voice behavior via voice efficacy. The results of a pretest of 302 employees using critical thinking questionnaires and a field study of 273 dyads of supervisors and their subordinates revealed that both employees’ critical thinking and leaders’ inspirational motivation had a positive effect on employees’ voice and that voice efficacy mediates the relationships among employees’ critical thinking, leaders’ inspirational motivation, and employees’ voice. Implications for research and practice are discussed.
