Generativity as a heuristic for impact-driven scholars addressing grand challenges.

In this contribution, we theorize generativity as a heuristic for impact-driven management scholars seeking to address grand challenges through research. We use generativity to connote the engagement of diverse actors in pluralistic inquiry to create conditions for future flourishing. Our theorization applies a pragmatist worldview and builds on insights from the multidisciplinary literature on generativity to envisage researchers as agents of care, collective learning, and transformative change.

The impact of vacation and job stress on burnout and absenteeism.

Abstract The purpose of the present study was to test the hypothesis that vacation relief decreases psychological and behavioral strains caused by job stressors. We examined the impact of job stress and vacation on strain on 87 blue-collar employees in an industrial enterprise in central Israel. Whereas former respite research focused on the impact of vacation only on psychological strains such as burnout and job and life satisfaction, the current study also examined a behavioral strain, absenteeism.

Optical properties of Nannochloropsis sp and their application to remote estimation of cell mass.

The absorption and scattering coefficients and reflectance spectra of ultra-high density Nannochloropsis occulata cultures were investigated in detail to identify the optical properties of the cultures and devise algorithms for remote estimation of dry cell mass in ultra-high cell density cultures. High-spectral resolution measurements of apparent absorption and attenuation as well as reflectance from 400 to 900 nm were carried out in relation to the dry weight, cell count, and pigment concentration in outdoor cultures. Indices calculated as (R(NIR) - R(red))/(R(NIR) + R(red)) and R(NIR)/R(red), in which R(NIR) is reflectance in the range from 750 to 800 nm and R(red) is reflectance in the range 670-680 nm, were used for remote assessment of dry cell mass.
