Twenty essays based on papers delivered at the International Symposium on the Varieties of Marxism held at the VanLeer Jerusalem Foundation 16-19 June 1974 and dedicated to the memory of George Lichtheim, an eminent historian of Marxism. The overall message is that, far from being a monolithic, crystal clear explanation of the universe, Marxism continues to be a multi-faceted ideology with diverse expressions in diverse cultures, spawning a wide spectrum of "official" prophets, each sincerely convinced that he or she is (...) correct and all others are wrong. Kamenka in his contribution, while somewhat too easily chiding Marx for being too absolute in his prescriptive ethics, suggests that the varieties of Marxism stem from "ambiguities and tensions at the very heart of Marx’s thought," and that it "speaks to us, like Christianity, with many voices and in accents that are at best suggestive and at worst deliberately seductive rather than precise". Eight of the articles, including that of Kamenka, can be described as being theoretical, concerned about clarification of such questions as the methodology of Marx, the place of Engels in Marxism, Marxian Ethics, Totality in Lukacs and Adorno, Sartrean Marxism, the transformation of the concept of practice from Kant via Marx to Lukacs, and the reawakened interest in the "Asiatic Mode of Production" as a stage in the evolution towards Socialism. Ten articles discuss the manifestations of Marxism in Western Europe, Russia, Italy, Zionism, the Arab world, Czechoslovakia, Poland, Latin America, and the radical student movements of the 1960s in the United States, France, and Israel. Two other articles examine the differences and reasons for differences with Marx expressed by two major commentators, Trotsky and Mao. (shrink)

This study comparatively examines the dividends behavior in state-controlled firms versus family-controlled firms. With the sample of large industrial firms listed on the Main Board of Hong Kong Stock Exchange, we investigate the dividends payment rates, stability of dividends payment, the effects of firm size, profitability and growth opportunity on likelihood to pay dividends, as well as the concentration of dividend in state-controlled versus family-controlled firms. Based on the findings, we derive some ethical implications of dividends policy regarding the differences (...) in business ethical behavior, corporate social responsibility, corporate governance, business sustainability, and shareholder activism in state-controlled versus family-controlled firms, as well as the improvement in these respects through cross-listing in Hong Kong.

Using electromagnetic levitation in combination with the oscillating drop technique and drop calorimeter method, the surface tensions and specific heats of undercooled liquid Co-10 wt% Mo, Co-26.3 wt% Mo, and Co-37.6 wt% Mo alloys were measured. The containerless state during levitation produces substantial undercoolings up to 223 K , 213 K and 110 K respectively for these three alloys. In their respective undercooling ranges, the surface tensions were determined to be 1895 m 0.31, 1932 m 0.33, and 1989 m 0.34 (...) mN m m 1 . According to the Butler equation, the surface tensions of these three Co-Mo alloys were also calculated, and the results agree well with the experimental data. The specific heats of these three alloys are determined to be 41.85, 43.75 and 44.92 J mol m 1 K m 1 . Based on the determined surface tensions and specific heats, the changes in thermodynamics functions such as enthalpy, entropy and Gibbs free energy are predicted. Furthermore, the crystal nucleation, dendrite growth and Marangoni convection of undercooled Co-Mo alloys are investigated in the light of these measured thermophysical properties. (shrink)

Gravitational decoherence (GD) refers to the effects of gravity in actuating the classical appearance of a quantum system. Because the underlying processes involve issues in general relativity (GR), quantum field theory (QFT), and quantum information, GD has fundamental theoretical significance. There is a great variety of GD models, many of them involving physics that diverge from GR and/or QFT. This overview has two specific goals along with one central theme:(i) present theories of GD based on GR and QFT and explore (...) their experimental predictions;(ii) place other theories of GD under the scrutiny of GR and QFT, and point out their theoretical differences. We also describe how GD experiments in space in the coming decades can provide evidence at two levels:(a) discriminate alternative quantum theories and non-GR theories;(b) discern whether gravity is a fundamental or an effective theory.

The apolipoprotein E gene plays an important role in the pathogenesis of Alzheimer's disease , and amyloid plaque comprised mostly of the amyloid-beta peptide ) is one of the major hallmarks of AD. However, the relationship between these two important molecules is poorly understood. We examined how A treatment affects APOE expression in cultured cells and tested the role of the transcription factor NF-B in APOE gene regulation. To delineate NF-B's role, we have characterized a 1098 nucleotide segment containing the (...) 5'-flanking region of the human APOE gene . Sequence analysis of this region suggests the presence of two potential NF-B elements. To demonstrate promoter activity, the region was cloned upstream of a promoterless luciferase gene. This segment was able to drive expression of luciferase in transient transfections of human fetal glial cells. Promoter activity was stimulated twofold by A treatment. Pretreatment with double-stranded DNA decoy oligonucleotides against NF-B reduced A stimulation. Deletion and mutagenetic analyses demonstrated that the distal NF-B element was functional and showed a strong DNA-protein complex band in gel shift analysis, similar to that from control NF-B consensus element. An anti-inflammatory and anti-NF-B drug, sodium salicylate, significantly blocked A-induced APOE promoter function. Our data provide evidence that upregulation of APOE by A in astroglial cells is mediated by an NF-B-element present in the 5'-flanking region of the APOE gene. (shrink)

This study aims to provide an integrated perspective on job crafting and its antecedents through the exploration of the joint effects of individual-level and team-level job crafting on employee work engagement. Drawing on conservation of resources (COR) theory, we propose that engaging in job crafting behaviors is promoted by the presence of job-related resources. In turn, job crafting is expected to result in higher levels of work engagement. We expect this reasoning to hold for the individual as well as the (...) team/collective levels. The hypotheses were tested using data from 287 medical professionals from 21 hospital units of a Chinese public hospital. Findings from two-level Bayesian structural equation modeling supported the idea that at the individual level, individual job crafting behaviors partially mediated the relationship from individual resources to individual work engagement. Further, collective crafting mediated the relationship from team resources to individual work engagement. In addition, a positive cross-level relation between collective crafting and individual crafting was found. We conclude that stimulated by resources, both job crafting processes at the individual-level and team-level can promote individual work engagement in Chinese employees. (shrink)

We present a framework for analyzing black hole backreaction from the point of view of quantum open systems using influence functional formalism. We focus on the model of a black hole described by a radially perturbed quasi-static metric and Hawking radiation by a conformally coupled massless quantum scalar field. It is shown that the closed-time-path (CTP) effective action yields a non-local dissipation term as well as a stochastic noise term in the equation of motion, the Einstein–Langevin equation. Once the thermal (...) Green's function in a Schwarzschild background becomes available to the required accuracy, the strategy described here can be applied to obtain concrete results on backreaction. We also present an alternative derivation of the CTP effective action in terms of the Bogolyubov coefficients, thus making a connection with the interpretation of the noise term as measuring the difference in particle production in alternative histories.

Abstract. There is an ongoing debate in the philosophical and jurisprudential literature regarding the nature and possibility of Contract theory. On one hand, are those who argue (or assume) that there is, or should be, a single, general, universal theory of Contract Law, one applicable to all jurisdictions and all times. On the other hand, are those who assert that Contract theory should be localized to particular times and places, perhaps even with different theories for different types of agreements. This (...) article considers one facet of this debate: evaluating the relevance of the fact that the remedies available for breach of contract can vary significantly from one jurisdiction to another. This wide variation in remedies for breach of a (contractual) promise is one central difference between promises in morality and enforceable agreements in law. The article asserts that variation of remedies strongly supports the conclusion that there is (and can be) no general, universal theory of Contract Law. (shrink)

This article proposes a moderated mediation model of emotional dissonance. In the model, emotional leadership negatively affects emotional dissonance, which, in turn, negatively affects helping behavior. Furthermore, the negative effect of emotional dissonance is assumed to be moderated by work-family conflict. Direct effects from both emotional leadership and work-family conflict to helping other behavior are also considered. Previous studies have neglected the mechanism of emotional dissonance, but this paper fills the gap with a moderated mediation model of emotional dissonance. This (...) article not only provides an incremental contribution to the emotional dissonance literature but also suggests means by which companies might enhance employe helping behaviors in order to achieve greater organizational efficiency.
