Relational demography in supervisor- subordinate dyads: Impact on subordinate job satisfaction, burnout, and perceived procedural justice

Abstract: Summary Although research has shown that demographic dissimilarity within groups is negatively associated with organizational attachment-orientated variables, few studies have investigated its relations with other job-related variables. Focusing on relational demographics within the context of superior-subordinate dyads, associations between relational demographic characteristics and subordinate job attitudes and perceptions were examined using polynomial regression. Relational race was found to correlate with perceptions of procedural justice and job satisfaction, but not job burnout. The implications of these findings for future relational demographic research are discussed. ? 1997 by John Wiley & Sons, Ltd. J. Organiz. Behav. 18: 351-362 (1997)

Disabuse of the drug metaphor: Psychotherapy process-outcome correlations.

Abstract: The drug metaphor suggests that if a process component (e.g., interpretation) is an active ingredient of a successful psychotherapy, then administering a relatively high level of it should yield a relatively positive outcome, and levels of the process component and the outcome should be correlated across clients. Measures of 5 theoretically relevant, reliably measured verbal process components were compared with the rate of change in 3 standard symptom intensity measures across the brief treatments of 39 (mainly depressed) psychotherapy clients. The expected significant process-outcome correlations were not found. These results are discussed as they illuminate some misleading assumptions that underlie many conventional studies of psychotherapy process and outcome.

Postural instability and motion sickness in a fixed-base flight simulator

Abstract: We evaluated the prediction that postural instability would precede the subjective symptoms of motion sickness in a fixed-base flight simulator Participants sat in a cockpit in a video projection dome and were exposed to optical flow that oscillated in the roll axis with exposure durations typical of flight simulation The frequencies of oscillation were those that characterize spontaneous postural sway during stance Head motion was measured prior to and during exposure to imposed optical flow Of 14 participants, 6 were classified as motion sick, either during or after exposure to the optical oscillation Prior to the onset of subjective symptoms, head motion among participants who later became sick was significantly greater than among participants who did not become motion sick We argue that the results support the postural instability theory of motion sickness Actual or potential applications include the prevention or mitigation of motion sickness in virtual environments

Earthquakes Induced by Hydraulic Fracturing in Poland Township, Ohio

Abstract: Felt seismicity induced by hydraulic fracturing is very rare, with only a handful of reported cases worldwide. Using an optimized multistation cross‐correlation template‐matching routine, 77 earthquakes were identified in Poland Township, Mahoning County, Ohio, that were closely related spatially and temporally to active hydraulic fracturing operations. We identified earthquakes as small as local magnitudes ( M L) ∼1 up to 3, potentially one of the largest earthquakes induced by hydraulic fracturing in the United States. These events all occurred from 4 to 12 March 2014, and the rate decayed once the Ohio Department of Natural Resources issued a shutdown of hydraulic fracturing at a nearby well on 10 March. Using a locally derived velocity model and double‐difference relocation, the earthquakes occurred during six stimulation stages along two horizontal well legs that were located ∼0.8 km away. Nearly 100 stimulation stages in nearby wells at greater distances from the earthquake source region did not coincide with detected seismicity. During the sequence, hypocenters migrated ∼600 m along an azimuth of 083°, defining a vertically oriented plane of seismicity close to the top of the Precambrian basement. The focal mechanism determined for the M L 3 event had a vertically oriented left‐lateral fault plane consistent with the earthquake distribution and the regional stress field. The focal mechanism, orientation, and depth of hypocenters were similar to those of the 2011 Youngstown earthquake sequence that occurred 18 km to the northwest and was correlated with wastewater injection instead of hydraulic fracturing. Considering the relatively large magnitude of the Poland Township events and the b ‐value of 0.89, it appears the hydraulic fracturing induced slip along a pre‐existing fault/fracture zone optimally oriented in the regional stress field.

Identifying the Drivers of Social Entrepreneurial Impact: Theoretical Development and an Exploratory Empirical Test of SCALERS

Abstract: The scaling of social entrepreneurial impact is an important issue in the field of social entrepreneurship. While researchers have focused relatively little theoretical and empirical attention on scaling, a recently proposed set of drivers of scaling – incorporated into what has been labeled the SCALERS model – may provide guidance for new theoretical and empirical work on scaling of social impact. In this study, prior work on the drivers of scaling is extended by adding to the theoretical foundations upon which the SCALERS model is developed and by providing an initial empirical test of the SCALERS model. Initial empirical support is found for the SCALERS model of scaling social entrepreneurial impact.
