This study explores linkages between what Chinese managers generally know about environmental issues, how strongly they value environmental protection, and different types of behaviours/actions they may take within their organizations on behalf of the environment. From a sample of 305 managers in Guangzhou and Beijing, it was found that both environmental knowledge and values are more predictive of more personal managerial behaviours, such as keeping informed of relevant company issues and working within the system to minimize environmental impacts, than more (...) overt behaviours. Moreover, for these more personal actions, environmental knowledge and values were found to have both main and interactive effects. By comparison, it was found that both environmental values and knowledge had additive effects on managerial tendencies to initiate new programs within their domain of responsibility. Only environmental values was found to have a modest influence environmental advocacy. (shrink)

This paper investigates the characteristics of firms which have underrepresented groups in top management positions and those which do not. It is argued that profiles of these characteristics will be different for firms with minorities vs. women and that these profiles will be different depending on whether representation is by board membership or through officerships. A discriminant analysis found both similarities and differences in variables that were associated with these different forms of representation. It was found, for example, that size (...) is associated with representation for both minorities and women, whereas high advertising intensity is associated with firms with women on board, but not as officers. Other findings and the implications of the study are discussed. (shrink)

This study investigates the relationship between workers'' perceptions of distributive and procedural justice afforded by a grievance system and their more general belief in an underlying moral order in the workplace. Using samples representing five ocupationally distinct groups, the presence of any moderating effects of occupation received only weak support. Consistent with previous work, however, workers'' perceptions of procedural justice (i.e., fairness in the process) were a stronger predictor of workers'' belief in workplace justice than were perceptions of distributive justice (...) (i.e., fairness of outcomes). (shrink)

This study examines the relationship between corporate diversification strategy and the pollution activity of subsidiaries within the U.S. chemical industry using TRI data (EPA's Toxic Release Inventory). The subsidiaries of conglomerates were found to exhibit higher pollution levels for direct emissions than those of firms pursuing more related diversification strategies. Additionally, the subsidiaries of conglomerates exhibited more variance in overall pollution emissions compared to related diversified firms.

Various corporate social activities were regressed on self-report measures of stakeholder-orientations from 220 CEOs from large Fortune 500 industrial and service firms. Overall, the relationship between who CEOs say is important and corporate activities toward those stakeholders is much weaker than anticipated. Of the expected relationships, only corporate philanthropy was positively related to CEO community orientation. The few other significant findings were less straightforward. Return on equity (ROE) of the company was related to the CEO's customer orientation rather than the (...) CEO's stockholder orientation, and liberal HRM programs were positively associated with a CEO's stockholder orientation rather than employee orientation. (shrink)

Collectively, institutions own an increasing proportion of outstanding corporate equities. As an emergent force in shaping corporate America, the linkages between institutional ownership and corporate social performance (CSP) require empirical examination. Not only do corporate policy makers need to know those areas where social performance may lure or inhibit capital infusions, lawmakers also need a better understanding of the social forces guiding corporate policy. As anticipated, this study found a positive relationship between the amount of institutional ownership of corporate stock (...) and a company's social responsiveness as measured by the representation of women on its board of directors; however, no statistically significant relationship with social responsibility as measured by charitable giving was found. The exemplar of social issues management — compliance with the Sullivan principles — showed an unexpected, negative relationship with the level of institutional ownership. (shrink)

Corporate political action committees (PACs) play a prominent role in the political strategies of U.S. organizations, and the ability of firms to influence political outcomes is highly controversial. To the extent that PACs enable groups of firms to pursue corporate agendas at the expense of the social good, they promote socially suboptimal outcomes. This study examines the impact of corporate PACs on entry restriction in manufacturing industries and finds a negative relationship between corporate PAC spending and the entry of new (...) firms. Results suggest that PACs are used to shape industry structure to the economic benefit of incumbents. (shrink)

Since locke, introspection has been generally defined as a form of observation. this is true, for example, of the classical tradition in psychology exemplified by wundt and titchener. recent experimental work by cognitive psychologists continues to treat introspection as a mode of observation while denying its alleged success in identifying cognitive processes. besides psychologists, philosophers such as james, ryle, and quinton are discussed, and they, too, define introspection as a type of observation analogous to perception. the present article calls attention (...) to other concepts of introspection that are important but that have figured less prominently in the history of philosophy and psychology. it is agreed here that, so far as the goals of self-knowledge and self-control are concerned, a concept of introspection other than that of observation is the significant one. explicating the nature of this alternative concept of introspection and its relevance for self-knowledge is the major aim of the article.

James argued that time is a sensation, and the main point of this paper is to deny that claim. The concept of the specious present is explained, indicating how it clarifies the concept of "the present moment." But neither it nor an argument used by Mach and James show time to be a sensation. The analysis presented here requires distinguishing concepts of sensation from concepts of temporal relations. James' view is really a theory that time-as-duration is sensed. But this assumes (...) that the description of time as sensed is also a description of time as an objective property of independent events. This is nowhere established, and making it plausible is a recurrent problem for philosophies like neutral monism and radical empiricism. (shrink)

Over many centuries, the homing pigeon has been selectively bred for returning home from a distant location. As a result of this strong selective pressure, homing pigeons have developed an excellent spatial navigation system. This system passes through the hippocampal formation, which shares many striking similarities to the mammalian hippocampus; there are a host of shared neuropeptides, interconnections, and its role in the storage and manipulation of spatial maps. There are some notable differences as well: there are unique connectivity patterns (...) and spatial encoding strategies. This review summarizes the comparisons between the avian and mammalian hippocampal systems, and the responses of single neurons in several general categories: location and place cells responding in specific areas, path and goal cells responding between goal locations, context-dependent cells that respond before or during a task, and pattern, grid, and boundary cells that increase firing at stable intervals. Head-direction cells, responding to a specific compass direction, are found in mammals and other birds but not to date in pigeons. By studying an animal that evolved under significant adaptive pressure to quickly develop a complex and efficient spatial memory system, we may better understand the comparative neurology of neurospatial systems, and plot new and potentially fruitful avenues of comparative research in the future.

The notion of a weakly scattered theory T is defined. T need not be scattered. For each a model of T, let sr() be the Scott rank of . Assume sr() ≤ ω\sp A \sb 1 for all a model of T. Let σ\sp T \sb 2 be the least Σ₂ admissible ordinal relative to T. If T admits effective k-splitting as defined in this paper, then θσ\cal Aθ\cal A$ a model of T.

This almost self-contained introduction to higher recursion theory is essential reading for all researchers in the field.

Problems with the conceptual foundations of quantum mechanics date back to attempts by Max Born, Niels Bohr, Werner Heisenberg, as well as many others in the 1920s to continue to employ the classical concept of a particle in the context of the quantum world. The experimental observations at the time and the assumption that the classical concept of a particle was to be preserved have led to an enormous literature on the foundations of quantum mechanics and a great deal of (...) confusion then and now among non-physicists and students in any field that involves quantum theory. It is the historical approach to the teaching of quantum mechanics that is at the root of the problem. Spacetime is the arena within which quantum mechanical phenomena take place. For this reason, several Appendices are devoted to the nature of spacetime as well as to topics that can help us understand it such as vacuum fluctuations, the Unruh effect and Hawking radiation. Because of the success of quantum mechanical calculations, those who wish to understand the foundations of the theory are often given the apocryphal advice, "just ignore the issue and calculate". It is hoped that this book will help dispel some of the dismay, frustration, and confusion among those who refuse to take to heart this admonition. (shrink)

Charge, like mass in Newtonian mechanics, is an irreducible element of electromagnetic theory that must be introduced ab initio. Its origin is not properly a part of the theory. Fields are then defined in terms of forces on either masses—in the case of Newtonian mechanics, or charges in the case of electromagnetism. General Relativity changed our way of thinking about the gravitational field by replacing the concept of a force field with the curvature of space-time. Mass, however, remained an irreducible (...) element. It is shown here that the Reissner-Nordström solution to the Einstein field equations tells us that charge, like mass, has a unique space-time signature. (shrink)

As fundamentalist religious thought strengthens its hold on U.S. politics and increases its role in politics around the world, enlightened values that form the very foundation of modern society are coming under attack. This essay explores some ramifications of these current conflicts.

This is the first comprehensive interpretive and critical analysis of the thought of one of America's foremost phiolosophers and psychologists- William James.

, a notion of forcing over E, the E-closure of L, is said to be effective if every sideways -generic extension preserves E-closure. There are set notions of forcing in E that do not preserve E-closure. The main theorem below asserts that is effective if and only if it is locally proper, a weak variant of Shelah's notion of proper.

Our ultimate purpose is to give an axiomatic treatment of recursion theory sufficient to develop the priority method. The direct or abstract approach is to keep in mind as clearly as possible the methods actually used in recursion theory, and then to formulate them explicitly. The indirect or experimental approach is to look first for other mathematical theories which seem similar to recursion theory, to formulate the analogies precisely, and then to search for an axiomatic treatment which covers not only (...) recursion theory but also the analogous theories as particular cases.The first approach is more general because it does not depend on the existence of analogues. A concrete mathematical theory, it seems, need have no such analogues and still be important, as e.g. classical number theory. In such a case, an axiomatic treatment may still be useful for exhibiting the mathematical structure of the theory considered and the assumptions on which it rests. However, it will lack one of the most heavily advertised advantages of the axiomatic method, namely, the “economy of thought” which results from an uniform theory for several different and interesting cases: we cannot hope for this if, by hypothesis, we know of only one particular case. In contrast, the second approach, if successful at all, is bound to achieve such “economy” because we start out with several interesting particular cases. Another possible virtue of the second approach is that of field work over insight: the abstract pattern that we are looking for and hoping to formalize in axioms, may not be evident in any one mathematical theory, but may spring to the eye if one happens to look simultaneously at several theories which happen to realize the pattern.

The lambda model of servocontrol seems superior to the alpha model in terms of dealing with the mechanical complexities of nonlinear and multiarticular muscles. Both, however, can be trivialized by noting that the “control variable” may simply be the sum of descending influences at propriospinal interneurons in the case of the lambda model or in the muscles themselves in the case of the alpha model. The notion that the brain explicitly computes output in terms of any such control variables may (...) be an engineering metaphor, useful for conceptual understanding but not for generating predictive hypotheses about higher motor circuitry.
