A fuzzy symmetric threshold (ST) function is defined to be a fuzzy set over the set of functions. All ST functions have full memberships in this fuzzy set. For n variables, there are (2n+2) ST functions. A distance measure between a nonsymmetric threshold function and the set of all ST functions is defined and investigated. An explicit expression for the membership function of a fuzzy ST function is defined through the use of this distance measure. An algorithm for obtaining this distance measure is presented with illustrative examples. It is also shown that any function and its complement always have the same grade of membership in the class of fuzzy ST functions. Applications to concise function representation and simple function implementation are also presented with examples. In addition, most inseparable unsymmetric functions are defined and investigated. Fuzzy ST functions are relevant to the development of practical applications of fuzzy methods and might contribute to the state of the art in the implementations of fuzzy methods in the areas requiring utilization of ST functions.

The authors generalize the standard linear-in-means model to allow for multiple types with between and within-type interactions. The authors provide a set of identification conditions of peer effects and consider a two-stage least squares estimation approach. Large sample properties of the proposed estimators are derived. Their performance in finite samples is investigated using Monte Carlo simulations.

Regression discontinuity designs have become popular in empirical studies due to their attractive properties for estimating causal effects under transparent assumptions. Nonetheless, most popular procedures assume i.i.d. data, which is unreasonable in many common applications. To fill this gap, we derive the properties of traditional local polynomial estimators in a fixed- G setting that allows for cluster dependence in the error term. Simulation results demonstrate that accounting for clustering in the data while selecting bandwidths may lead to lower MSE while maintaining proper coverage. We then apply our cluster-robust procedure to an application examining the impact of Low-Income Housing Tax Credits on neighborhood characteristics and low-income housing supply.

This paper presents an analysis of interview data and field notes from participant observation collected during a four‐month period to discover different work‐related cultural assumptions between Chinese and American co‐workers in a multicultural organization. The paper also addresses how those different cultural assumptions which guide the ways Chinese and American workers conceptualize their jobs and job behaviors lead to conflict as the employees go about their daily business. The contrasting cultural assumptions discussed in the paper are (1) Chinese and American views of the role of manager and the practice of “managing,” (2) Chinese and American conceptualizations of good service, and (3) Chinese and American perspectives of compensation. Finally, the paper discusses some theoretical and methodological implications of the current study and its research method for future studies of cultural and conflict in multicultural contexts.

This paper explores the nonlinear interactions of research and development (R&D) and advertising and their synergistic effect on firm performance using Tobin's Q. This study also aims to investigate differential synergy patterns under varying levels of exports with a precision impact on performance.

Unlike a conventional statistical approach, this study uniquely presents a neural network approach to explore the dynamic interplay of strategic factors. A multilayer perceptron neural network (MPNN) is designed to capture complex interaction patterns through a predictive analytic process.

This study finds that the impact of R&D and advertising is positive, with a greater effect on high-export firms. Moreover, the experiment results show that the synergy of R&D and advertising goes beyond the formatted positive/negative frame and actually has a reinforcing effect.

This study not only conveys the significant nexus of R&D and advertising for firm performance but also provides industry managers' practical means to assess the joint effect of R&D and advertising on firm performance. The proposed analytic mechanism in particular provides pragmatic decision support to managers in harmonizing their R&D and advertising efforts for a foreseeable impact.

This paper presents an innovative analytic process using the MPNN to explore the synergy between R&D and advertising. In addition to offering new perspectives on R&D and advertising, this study presents pragmatic implications for managing those strategic resources to meet performance targets.

John Buckley is something of a corporate knight, coming to the rescue of companies in distress. Having masterminded the recovery of Davy International, Buckley has been reviving one of the best known names in the machine tool business. The task, he tells Ken Gooding, is like “performing surgery without anaesthetic”.

One of the basic problems hindering effective implementation of the physical distribution management (PDM) concept in many companies today is organisational rigidity. By this is meant the inability and unwillingness of management to respond to the changing demands of new concepts and new techniques inherent in the successful adoption of PDM in existing corporate organisations. This rigidity manifests itself in two related ways: firstly, in the relationships structure within an organisation, and the place of physical distribution relative to other functional areas in management, such as marketing, production, finance, etc., and secondly, in the characteristics of distribution executives and their perceived role within an organisation.

This chapter describes, both from a personal and historical perspective, the ascendancy and incumbency of Leroy D. Baca as sheriff of Los Angeles County, comparing and contrasting his leadership, ensconced in new age terminology, with that of his predecessors, Sherman Block and Peter J. Pitchess. Of immediate concern were his personal decisions, in particular the appointment of Paul Tanaka to be his undersheriff after many years serving as his campaign treasurer. What was considered a marginally functional merit-based promotional system was transformed into a political patronage model, with the attendant loss of organizational legitimacy and tarnished public reputation. The chapter will compare and contrast life within the “car,” as the term is commonly used within the Los Angeles County Sheriff’s Department, and life outside the car, through first-hand accounts, testimony from the Citizen’s Commission on Jail Violence, depositions, and published reports. Using the concept of representative bureaucracy, I will track organizational diversity as a performance measure, using the relative inclusion of all employee groups in the rank structure of the department and how each group fared under the Baca/Tanaka administration. In conclusion, this chapter will present different coping mechanisms utilized by employees confronting serious corruption issues that impacted them directly, and indirectly through the organization.

The purpose of this paper is to contrast conventional economists' belief that human needs are optimally satisfied by the market, with Marx's view that capitalism has a narrow focus on money making, where satisfying human needs is at most a by‐product of the system's restricted purpose.

The paper explores conventional economics, then Marx's economics, focusing on the issue of saving the environment, as the most basic human need is having a viable environment.

Economists' focus on use‐value and optimality is explored. Marx's alternative explanation of capitalism is then introduced. The author explains why Marx thinks capitalism has a tendency to boom and slump and to produce rising levels of inequality and considers how, under capitalism, the environment could be saved, and concludes that both human needs and the environment are best secured in a more advanced social system than capitalism.

To properly understand capitalism, one must look to Marx's unsurpassed analysis of capitalism, rather than conventional economists' attempts to justify, but not actually explain, capitalism.

Saving the environment is likely to be far more difficult and disruptive to the economy than conventional economists imagine.

For society to actually focus on satisfying human needs, including, crucially, saving the environment, there needs to be a move to a more advanced social system than capitalism.

The paper challenges orthodox views by applying Marx's deeper understanding of the economy to the question of human needs/the environment.
