We define some variations of the Scott rank for countable models and obtain some inequalities involving the ranks. For mono-unary algebras we prove that the game rank of any subtree does not exceed the game rank of the whole model. However, similar questions about linear orders remain unresolved.

An inclusive vision of mathematics-- its beauty, its humanity, and its power to build virtues that help us all flourish. For mathematician Francis Su, a society without mathematical affection is like a city without museums. To miss out on mathematics is to live without experiencing some of humanity's most beautiful ideas. In this profound book, written for a diverse audience but especially for those disenchanted by their past experiences, an award-winning mathematician and educator weaves personal reflections, puzzles, and stories to (...) show how mathematics meets basic human desires and cultivates virtues essential for human flourishing. Readers will explore mathematical concepts-- and see how mathematical thinking can even fulfill such longings as for love, play, freedom, justice, and community. Some lessons come from those who have struggled, including philosopher Simone Weil, whose own mathematical contributions were overshadowed by her brother's, and Christopher Jackson, who discovered mathematics as an inmate in a federal prison. Christopher Jackson's letters to the author appear throughout the book and show how this intellectual pursuit can-- and must-- be open to all. (shrink)

Enterprise philanthropy is practiced in a very unique and rudimentary form in China. Based on a unique random survey data on 3837 Chinese private enterprises conducted in 31 provinces of China in 2006, I find the significant positive relationship between enterprise philanthropy donation and enterprise profitability, and the result supports the political and institutional power view of enterprise philanthropy in the latest development of China. Simply put, Chinese private enterprises carried out philanthropy activities to better protect property rights and nurture (...) political connections, which in turn, leads to better enterprise profitability. The␣result is even stronger in institutions weaker provinces. (shrink)

Gender segregation in baccalaureate degree fields declined rapidly in the first half of the period from 1971 to 2002; at the same time, women's representation among baccalaureate degree recipients increased most rapidly relative to men's. The desegregation of the early period resulted mainly from women's increased entry into business-related fields and declining proportions of women majoring in traditional fields such as education and English. Men did not contribute to integration by moving toward fields numerically dominated by women. Fixed-effects regression models (...) suggest that feminization of fields discourages later cohorts of men from entering them, as predicted by the devaluation perspective. The stalling of desegregation came from a combination of men's disinclination to enter fields that are “too” filled with women, and the slowdown in women making less traditional choices. (shrink)

The aim of this study was to investigate factors associated with seriously ill patients’ preferences for their family and physicians making resuscitation decisions on their behalf. Using SUPPORT II data, the study revealed that, among 362 seriously ill patients who were experiencing pain, 277 (77%) answered that they would want their family and physicians to make resuscitation decisions for them instead of their own wishes being followed if they were to lose decision-making capacity. Even after controlling for other variables, patients (...) who preferred the option of undergoing cardiopulmonary resuscitation (CPR) in the future were twice as likely, and those who had had ventilator treatment were four-fifths less likely, to rely on their family and physicians than those who did not want CPR (odds ratio (OR)-2.28; 95% confidence interval (CI) 1.18-4.38) or those who had not received ventilator treatment (OR-0.23; 95% CI 0.06-0.90). Psychological variables (anxiety, quality of life, and depression), symptomatic variables (severity of pain and activities of daily living) and the existence of surrogates were not significantly associated with patients’ preferences for having their family and physicians make resuscitation decisions for them. Age was not a significant factor for predicting the decision-making role after controlling for other variables. (shrink)

Dieses Buch verteidigt die These, dass bis auf leicht ausgrenzbare Ausnahmen die Ersetzung von Synonyma in einem Satz die Wahrheit oder Falschheit des Satzes nicht beeinflusst. Maik Sühr liefert eine sorgsame Formulierung der These, indem er sie aus dem im Allgemeinen akzeptierten Prinzip der Kompositionalität ableitet. Er konfrontiert sie im Anschluss mit zum Teil noch weithin unbekannten augenscheinlichen Gegenbeispielen und macht eine Reihe von neuen Vorschlägen, um diese zu entkräften. In diesem Zusammenhang setzt sich Sühr mit verschiedenen Themen innerhalb der (...) Sprachphilosophie und der Philosophie des Geistes auseinander. So bespricht er u.a. Freges Sinnhierarchie, kognitive Äquivalenz sowie verschiedene Aspekte der Semantik von Allquantifikationen und weil-Sätzen. Ferner nimmt er mit neuen Argumenten Stellung zur Debatte zwischen Externalisten und Internalisten in Bezug auf mentalen Gehalt und plädiert für eine grundsätzliche Unterscheidung zwischen semantischen und mentalen Gehalt. Im Schlussteil wendet er die Ersetzbarkeits-These auf das sogenannte Paradox der Analyse an. Im Zuge seiner kritischen Diskussion verschiedener Theorien über Begriffsanalysen entwickelt er dabei seine eigene Konzeption von Analysen als Erklärungen. (shrink)

Guanxi (literally interpersonal connections) is in essence a network of resource coalition-based stakeholders sharing resources for survival, and it plays a key role in achieving business success in China. However, the salience of guanxi stakeholders varies: not all guanxi relationships are necessary, and among the necessary guanxi participants, not all are equally important. A hierarchical stakeholder model of guanxi is developed drawing upon Mitchell et al.’s (1997) stakeholder salience theory and Anderson’s (1982) constituency theory. As an application of instrumental stakeholder (...) theory, the model dimensionalizes the notion of stakeholder salience, and distinguishes between and among internal and external guanxi, core, major, and peripheral guanxi, and primary and secondary guanxi stakeholders. Guanxi management principles are developed based on a hierarchy of guanxi priorities and management specializations. The goal of this application of instrumental stakeholder theory is to construct, for Western business firms in China, a means to reliably identify guanxi partners by employing the principles of effective guanxi. These principles are described in the form of testable propositions that advance social scientific research in this area of international business ethics. (shrink)

Although Korean society has begun to seek a way of utilizing advance directives, there is not much known about the factors influencing the average Korean person’s preference toward advance directives. The purpose of this study was to examine factors, in addition to demographic variables, influencing preferences regarding advance directives. These include: to what extent people’s awareness of advance directives, preferences of extending their life at the end of life, experience of illness and medical care, and family functioning independently influence the (...) preferences toward advance directives. The participants were 382 community-dwelling Korean people. The data analysis was performed using hierarchical multiple logistic regression analysis. The findings showed that a majority of Korean people had a positive preference on advance directives and the factors influencing their preferences for advance directives were the preferences against the use of life-sustaining treatment at the end of life, a good self-rated heath status, and an unsatisfactory family functioning.

Partner selection is the primary aspect of the formation of knowledge collaboration teams. We propose a method of partner selection for KCTs based on a weighted social network analysis method in which the individual knowledge competence and the collaboration performance of candidates are both considered. To select the desired partners, a biobjective 0-1 model is built, integrating the knowledge competence and collaboration performance, which is an NP-hard problem. Then, a multiobjective genetic algorithm is developed to solve the proposed model. Finally, (...) a real-world example is provided to illustrate the applicability of the model, and the MOGA is implemented to search for Pareto solutions of partner selection for KCT in this case. Moreover, some simulation examples are used to test the efficiency of the algorithm. The results suggest that the proposed method can support effective and practical partner selection. (shrink)

This study explores the linear logic between consumer ethical beliefs (CEBs) and consumer unethical behavior (CUB) in a Chinese context. A relational view helps fill the belief–behavior gap by exploring the moderating role of relationship quality in reducing CUBs. Specifically, when consumers are more receptive to a set of actions that may be deemed inappropriate by moral principles, they are more likely to engage in unethical behaviors. However, when consumers perceive their misconduct as possibly damaging to the relationship developed with (...) the seller, they tend to refrain from unethical behaviors. CEBs and relationship quality also combine to affect unethical behaviors. Although consumers find the misconduct acceptable according to their ethical beliefs, they become less likely to conduct the behavior if they have a close relationship with the seller. The results contribute to a better understanding of the simplistic logic that connects CEBs and their unethical behaviors and shed light on how close relationships with consumers help contain CUBs.

Pylyshyn's effort in establishing the cognitive impenetrability of early vision is welcome. However, his view about the role of attention in early vision seems to be oversimplified. The allocation of focal attention manifests its effect among multiple stages in the early vision system, it is not just confined to the input and the output levels.

Strengthening a theorem of D.W. Kueker, this paper completely characterizes which countable structures do not admit uncountable L ω 1 ω -elementarily equivalent models. In particular, it is shown that if the automorphism group of a countable structure M is abelian, or even just solvable, then there is no uncountable model of the Scott sentence of M. These results arise as part of a study of Polish groups with compatible left-invariant complete metrics.
