What aspects of the job have most effect on nurses?

The study reported here compared the influences of psychological constructs (job demands and scheduling control) and objective work characteristics (shiftwork, night‐work and hospital department type) on job satisfaction, organisational commitment, burnout and withdrawal intentions. Our hypothesis was that psychological constructs have a higher influence on work‐related attitudes than objective characteristics of work schedules. In addition to the main effects, we proposed an interactive hypothesis: poor attitudes would result from high demands and low control rather than from other combinations of both psychological variables. Using a sample of 153 hospital nurses in Israel, the hypotheses were generally supported. As night‐work, shiftwork and working in intensive care units are unavoidable characteristics of the modern medical environment, these findings are meaningful for improving the personal adjustment of hospital nurses.     

The religious factor in private education

We quantify the religious factor in private education in the United States by calibrating a political economy model of school choice—among public, private-nonsectarian and subsidized religious schools—in which parents differ in their incomes and in their preferences for religious education. This shows strong latent demand for religious schooling, conditioned on current subsidized tuition levels in parochial schools, which is suppressed by the need to “pay twice” for private education. Applying the results of the calibration to gauge the effect of means-tested school voucher programs on religious and nonsectarian private enrollment, we find that when the amount of the voucher is relatively small, including subsidized religious schools in such programs is necessary for providing low-income families effective access to private education.     

A proposal for a more objective measure of de facto constitutional constraints

In this paper we propose two new indicators of de facto constitutional constraints. The indicators are based on the presence or the absence of easily observable political events. This makes the proposed measures relatively objective and easy to verify relative to the most widely used indicators of de jure and de facto constitutions. This paper describes the indicators and demonstrates their usefulness for research on economic development.     

Counterfactual analysis of bank mergers

We introduce a counterfactual analysis of banks mergers, combining the pre-merger equilibrium setting with post-merger environmental characteristics, while accounting for endogenously propagated changes in market structure. Using this procedure we are able to estimate the effects on loan flows and interest rates that would have been observed if the pre-merger equilibrium was not altered. Results are obtained for firms, households, and banks inside and outside the merging circles separately. We find that mergers increased firms’ access to credit, but had an opposite effect on households and led to a widespread decrease in interest rates.     

Ethno‐cultural considerations in negotiation: pretense,deception and lies in the Greek workplace

A retrospect into ethos, this study examines the impact of individualism, collectivism, ethical idealism and interpersonal trust on negotiators' attitudes toward questionable negotiation tactics in Greece. A thousand survey questionnaires were administered to Greek employees, of which 327 usable responses were collected. Our findings empirically corroborated a classification of three groups of negotiation tactics, namely, pretense, deception and lies. Individualism–collectivism and ethical idealism were found to be related, and interpersonal trust was found to be unrelated, to attitudes toward questionable negotiation tactics. Emphasizing the non‐US and non‐Western European nature of the empirical data collected, the originality of this research further stems from the development of a comprehensive research framework about questionable negotiation tactics in Greece.     

Optimization of the machining economics problem under the failure replacement strategy

This paper presents a model for calculating the optimal cutting feed rate and spindle speed in a stand-alone cutting machine. The optimal cutting conditions are determined for three different objective functions—minimum expected cycle time, minimum expected cost per unit, and maximum expected profit-rate—under the failure replacement strategy, taking into account cutting tool constraints and machine limitations. We also examine the relationships between the optimal solutions, and present the efficiency range of feed rate.     

Teamwork in Modern Organizations: Implications for Technology Education

Characteristics of teamwork in modern organizations and workplaces are examined, in order to extrapolate the means for imparting teamwork skills within technology education. Goals and tasks for the team, team composition, team-player styles, phases of team development, communication and interpersonal skills, decision making, leadership, and evaluation of team performance are discussed. Teamwork skills are acquired gradually as a result of experience. Mere provision of a joint task to a group of people does not produce teamwork spontaneously. In order to promote teamwork, technological tasks at school need to include considerable degrees of freedom and decision-making by pupils. When the teacher becomes a facilitator of the process, instead of being primarily a source of knowledge and a decision-maker, team members can determine the assignment of roles in the group by themselves. Evaluation of teamwork in technology education is an integral part of alternative assessment.     

k-Price Auctions

In this paper we analyze the equilibria structure of k-price auctions, k ≥ 3, under the independent-private-value assumption. We discuss agents with an arbitrary attitude toward risk. That is, agents may be risk averse or risk seeking, or they may have an alternating attitude toward risk. We provide a characterization of a continuous symmetric equilibrium, prove that there exists at most one such equilibrium, and show that every such equilibrium is differentiable and increasing. We also show some additional general properties of the equilibrium strategies in these auctions. Journal of Economic Literature Classification Numbers: C72, C73, D83.     

Economical evaluation of greenhouse layout design

This paper offers mutual exchange of knowledge and expertise between agriculture and production-economy by economical evaluation of greenhouses. Greenhouses are Hi-Tech horticulture farms, in which advanced technological infrastructure increase production efficiency by providing optimal growing conditions. However, this infrastructure involves high capital investments. There are other cost sources, of which labor is dominant, generally in horticulture and in greenhouses in particular. Efficient use of space and labor are often conflicting goals in greenhouse layout design. In this paper, these conflicts are presented and illustrated, and tools are developed to evaluate layout design by the resultant annual operational profit, thus enable comparison of alternative layouts. To increase accessibility, spreadsheet software is used for the calculations. Further, the spreadsheet is designed to support WHAT-IF analyses. The applicability of the proposed approach is demonstrated via numerical analyses of layout design of an actual greenhouse for pepper growing using the Holland method. Evidently, the layout design can have significant effect on the economical efficiency of the greenhouse—annual profit increases by, at least 12%, and up to 40%! The tradeoff between space utilization and resource utilization; e.g., labor, is common to all greenhouses, whether vegetables, flowers or other plants are grown in them and the tools presented herein can be easily modified to any desired case.
