Thriving in a self‐made niche: how to create a successful academic career in organizational behavior

Granting that organizational behavior may be a field with a weak paradigm, this can be viewed as an advantage rather than as a nemesis that makes success in an academic career nearly impossible for neophytes to the field. The weak paradigm allows many niches to emerge. A niche is an identifiable, circumscribed area of scholarly inquiry that can provide a good match with the individual's qualifications, interests, and career aspirations. Within these niches individual scholars can thrive. There a newcomer can find colleagues with similar interests, form partnerships, exchange information, and, in general, derive support for a career. Characteristics of niches are described and examples are provided. How niches evolve and the notion of creating one's own niche are discussed. The implications of the niche composition of organizational behavior for developing a successful academic career, and advice how to go about doing it, are provided. Tyros will fare much better if they adopt a niche strategy rather than seeing themselves as sitting ducks in a shooting gallery due to the role of chance factors in career advancement.

Using non-equilibrium biosorption column modelling for improved process efficiency

An unsteady-state biosorption column model in one space variable is considered in this paper. The theoretical study is motivated by the need for predicting the dependent variables of biosorption columns for removal of heavy metals from wastewater, which is potentially an important technology in cleaner production. Pollutant concentrations in the bulk phase, in the liquid filling the pores and in the solid biomass along the axial coordinate of the column were evaluated for a wide range of physical and chemical parameters of the global process. In particular, the assumption of instantaneous chemical reactions is replaced by a more realistic expression taking into account chemical kinetics and fluid advection time scales separately. The resulting system of partial differential equations was solved by means of a reliable numerical algorithm based on the method of lines. The data obtained using the model described in this paper are compared with published experimental data and an estimation of the increased efficiency is made.     

Work and nonwork relations: The conical structure of work and home life relationship

The major objective of the present study was to analyze the structure of work-nonwork relations. A definitional framework of the work-nonwork domain was first suggested, based on the extant literature. The definition was then empirically tested by applying Similarity Structure Analysis to analyze the data, collected from a sample of 106 Israeli workers. The results support the hypotheses of the study. An empirical double ordered conceptual system was obtained, reflecting the two facets of the definition: behavior modality (instrumental, affective and cognitive) and social environment (work and home). A general lawfulness of a conical type was found that relates the definitional framework with the empirical structure. The facet approach applied in this study suggests that the various aspects of the domain may be characterized by different patterns of relationships. The results showed a clear distinction between the work and home regions. Further analysis revealed a compensation type of relationship between home and work in the instrumental and cognitive items and segmentation in the affective items. The results thus support the facet approach rather than the conventional approaches which consider work and non-work as unitary concepts and attempt to establish which of three proposed patterns: compensation, spillover or segmentation, best characterizes their relationships.     

Improving construction site safety through leader-based verbal safety communication

Background

The construction industry is one of the most injury-prone industries, in which production is usually prioritized over safety in daily on-site communication. Workers have an informal and oral culture of risk, in which safety is rarely openly expressed. This paper tests the effect of increasing leader-based on-site verbal safety communication on the level of safety and safety climate at construction sites. Method: A pre-post intervention-control design with five construction work gangs is carried out. Foremen in two intervention groups are coached and given bi-weekly feedback about their daily verbal safety communications with their workers. Foremen-worker verbal safety exchanges (experience sampling method, n = 1,693 interviews), construction site safety level (correct vs. incorrect, n = 22,077 single observations), and safety climate (seven dimensions, n = 105 questionnaires) are measured over a period of up to 42 weeks. Results: Baseline measurements in the two intervention and three control groups reveal that foremen speak with their workers several times a day. Workers perceive safety as part of their verbal communication with their foremen in only 6-16% of exchanges, and the levels of safety at the sites range from 70-87% (correct observations). Measurements from baseline to follow-up in the two intervention groups reveal that safety communication between foremen and workers increases significantly in one of the groups (factor 7.1 increase), and a significant yet smaller increase is found when the two intervention groups are combined (factor 4.6). Significant increases in the level of safety are seen in both intervention groups (7% and 12% increases, respectively), particularly in regards to 'access ways' and 'railings and coverings' (39% and 84% increases, respectively). Increases in safety climate are seen in only one of the intervention groups with respect to their 'attention to safety.' No significant trend changes are seen in the three control groups on any of the three measures. Conclusions: Coaching construction site foremen to include safety in their daily verbal exchanges with workers has a significantly positive and lasting effect on the level of safety, which is a proximal estimate for work-related accidents. It is recommended that future studies include coaching and feedback at all organizational levels and for all involved parties in the construction process. Building client regulations could assign the task of coaching to the client appointed safety coordinators or a manager/supervisor, and studies should measure longitudinal effects of coaching by following foremen and their work gangs from site to site.     

Spatially explicit modeling of overstory manipulations in young forests: Effects on stand structure and light

Young forests can be manipulated in diverse ways to enhance their ecological values. We used stem maps from two dense, second-growth stands in western Washington and a spatially explicit light model (tRAYci) to simulate effects of five silvicultural manipulations on diameter distribution, species composition, spatial patterning, and light availability. Each treatment removed 30% of the basal area, but differed in how trees were selected for removal. Three primary treatments were thin from below (removing the smallest trees), random thin (removing trees randomly), and gap creation (removing all trees in circles ∼1 tree height in diameter). Two additional treatments combined elements of these approaches: random ecological thin (a mixture of thin from below and random thin) and structured ecological thin (a mixture of thin from below and gap creation).     

The use of supervisory practices as leverage to improve safety behavior: a cross-level intervention model

Introduction: The paper presents three intervention studies designed to modify supervisory monitoring and rewarding of subordinates' safety performance. Method: Line supervisors received weekly feedback concerning the frequency of their safety-oriented interactions with subordinates, and used this to self-monitor progress toward designated improvement goals. Managers higher up in the organizational hierarchy received the same information, coupled with synchronous data concerning the frequency of workers' safety behaviors, and highlighting co-variation of supervisory action and workers' behavior. Results: In all the companies involved, supervisory safety-oriented interaction increased significantly, resulting in significant changes in workers' safety behavior and safety climate scores. Continued improvement during the post-intervention period suggests the inclusion of workers' safety behavior as in-role supervisory responsibility. Applied and theoretical implications are discussed.     

Achievement motive and entrepreneurial orientation: a structural analysis

In this study we have attempted to assess the achievement motive of students of small business, considered as having high entrepreneurial orientations, and students of business and economics, considered as having lower entrepreneurial orientations. Based on a facet definition of achievement motive we analyzed the structure of achievement motive for both samples. As hypothesized, results reflected the three facets of achievement motive: type of confrontation, time perspective related to task performance, and behavior modality. As hypothesized, small business students were found to score higher than their business and economics colleagues on most of the achievement items. Considerable differences between the samples were found on four achievement components: the readiness to face uncertainty, calculating risk, undertaking personal responsibility, and solving problems. The discussion focused on the advantages of the multifaceted approach to achievement motive and implications for assessing it in various settings. Copyright © 1999 John Wiley & Sons, Ltd.     

Dry land tree management for improved household livelihoods: farmer managed natural regeneration in Niger

Farmer Managed Natural Regeneration (FMNR), a set of practices farmers use to foster the growth of indigenous trees on agricultural land, has drawn substantial attention as a contributing factor to a trend of increasing vegetation greenness in the Republic of Niger. This paper identifies drivers of FMNR adoption and assesses its impacts on rural households in the Region of Maradi, Niger, an area covering 42,000 square kilometers. The results show that 26% of households practice a form of FMNR involving both pruning and protecting woody vegetation. Adoption is strongly linked to soil type, market access, and the education level of the head of household. FMNR raises household income and increases crop diversity, household migration rates, and the density and diversity of trees on farmland. It is estimated that FMNR raises the annual gross income of the region by between 17 and 21 million USD and has contributed an additional 900,000 to 1,000,000 trees to the local environment. These findings support the value of continued promotion of FMNR as an inexpensive means of enhancing rural livelihoods and an attractive alternative to reforestation efforts relying on tree planting.
