The generation of doctorates and their feedback into higher education

The dynamic effects of alternative manpower policies and programs can be “pretested” in a computer based simulation. It is generally recognized that the production of Doctorates depends to a large degree on the Doctorate-holding faculty. Because the doctorate holders are in great demand by the other sectors of the economy, a circular or a “feedback” situation exists. The problem is further complicated by the availability of developed student talent and by various socioeconomic conditions existing at different periods of time within two or three decades prior to the time a study is made.

This paper attempts to develop a conceptual and a mathematical model to study the production of Doctorates, Masters' and Baccalaureate degrees and their feedback into higher education. The model consisting of over 200 non-linear difference equations is programmed for computer simulation and validation against historical data. Currently simulation is used to describe what has happened in the past. Once this phase is accomplished, the model can be used to prescribe what will happen in the future with a fair level of confidence.

Following the story: narrative mapping as a mobile method for tracking and interrogating spatial narratives

Museums and heritage tourism sites are highly curated places of memory work whose function is the assembling and ordering of space and narrative to contour visitors’ experiences of the past. Variations in such experiences within and between sites, however, necessitates a method that: (1) captures how guides, visitors, and exhibits interact within spaces when representing and performing history and (2) allows researchers to document those variations. We developed narrative mapping, a mobile and geographically sensitive form of participant observation, to enable museum scholars and professionals to systematically capture, visualize, and interpret tendencies and variations in the content, affective qualities, and spatial arrangements of museum narratives over multiple sites and across multiple tours at the same site. Two antebellum plantation museum case studies, Laura Plantation in Louisiana and Virginia’s Berkeley Plantation, demonstrate the method’s utility in documenting how stories are spatially configured and materially enlivened in order to analyze the ways enslaved persons are placed within these narratives.     

Enhancing green product and process innovation: Towards an integrative framework of knowledge acquisition and environmental investment

Despite the increasing interest in green innovation literature, little is known on how and under what conditions firms' knowledge transfer activities affect green innovation. There is lack of research that on how particular organizational capabilities are seen more useful and how it influences on green innovation performance. To address this research gap, we examine a mediation model in which we explore whether a firm's knowledge acquisition capability and investment in environmental management mediate the impact of buyer-driven knowledge transfer activities on green product innovation and green process innovation. On the basis of an analysis of a sample of 239 manufacturing firms, we find that buyer-driven knowledge activities have a greater positive impact on green product innovation than green process innovation. Investment in environmental management fully mediates the relationship between buyer-driven knowledge transfer activities and green process innovation, and knowledge acquisition capability partially mediates the relationship between buyer-driven knowledge transfer activities and green product innovation. The current study provides evidence that internal competencies and the role of buyers in knowledge transfer are critical for explaining the green product innovation and green process innovation. Our results suggest that buyer involvement pushes firms to develop resource acquisition capability to enhance green product innovation. Our results also highlight the importance of investment in environmental management for overcoming the environmental challenges in the manufacturing firms.

Managerial Discretion and Task Interdependence in Teams

This study investigates whether task interdependence in teams alters the effectiveness of managerial discretion in motivating team performance. Teams are particularly useful when employees' tasks are interdependent—that is, when the degree to which the increase in team performance resulting from a team member's effort depends on the effort and skills of the other team members. The reason is that the more interdependent tasks are, the more employees need to coordinate their actions and help one another to achieve their objectives. Prior research analyzing settings where task interdependence is absent suggests that providing managers with discretion over team bonus allocation can improve team performance relative to equal team bonus allocations because it strengthens the link between contributions to team output and rewards. Economic theory suggests that managerial discretion will also improve team performance when task interdependence is present and information is efficiently used. However, we use behavioral theory to predict that managerial discretion is less effective in the presence of task interdependence, because managers do not fully incorporate all relevant information into bonus decisions and because managerial discretion hurts coordination and helping, which is particularly problematic under task interdependence. We find that while discretion over compensation has a positive effect on team performance relative to equal bonus allocation when task interdependence is absent, it has a negative effect when task interdependence is present. Additional analyses provide support for our underlying theory. Results of our study contribute to both theory and practice by suggesting that, ironically, managerial discretion may be most useful when the potential benefits of employing teams are lowest and least useful when the potential benefits are highest. Our results help explain why firms often grant managers only partial or no discretion over team members' compensation.     

A Note on the Interdependence between Hypothesis Generation and Information Search in Conducting Analytical Procedures*

This study examines the linkage among the initial hypothesis set, the information search, and decision performance in performing analytical procedures. We manipulated the quality of the initial hypothesis set and the quality of the information search to investigate the extent to which deficiencies (or benefits) in either process can be remedied (or negated) by the other phase. The hypothesis set manipulation entailed inheriting a correct hypothesis set, inheriting an incorrect hypothesis set, or generating a hypothesis set. The information search was manipulated by providing a balanced evidence set to auditors (i.e., evidence on a range of likely causes including the actual cause ‐ analogous to a standard audit program) or asking them to conduct their own search. One hundred and two auditors participated in the study. The results show that auditors who inherit a correct hypothesis set and receive balanced evidence performed better than those who inherit a correct hypothesis set and did their own search, as well as those who inherited an incorrect hypothesis set and were provided a balanced evidence set. The former performance difference arose because auditors who conducted their own search were found to do repeated testing of non‐errors and truncated their search. This suggests that having a correct hypothesis set does not ensure that a balanced testing strategy is employed, which, in turn, diminishes part of the presumed benefits of a correct hypothesis set. The latter performance difference was attributable to auditors' failure to generate new hypotheses when they received evidence about a hypothesis that was not in the current hypothesis set. This demonstrates that balanced evidence does not fully compensate for having an initial incorrect hypothesis set. These findings suggest the need for firm training and/or decision aids to facilitate both a balanced information search and an iterative hypothesis generation process.
