Surveying the field of the economics of the household, the second edition of this text reviews the theory of the consumer at the intermediate undergraduate level. It then applies and extends it to consumer demand and expenditures, consumption and saving, time allocation among market work, home work, and leisure, human capital emphasizing investment in education, children and health, fertility, marriage, and divorce. Influenced by Gary Becker and his associates, the models developed are used to help explain modern U.S. trends in (...) family behavior. Topics are discussed with the aid of geometry and a little algebra. For those with calculus, mathematical endnotes provide the models on which the text discussions are based and interesting applications beyond the scope of the text. (shrink)

Shors & Matzel's conclusion that LTP is not related to learning is similar to one we reached several years ago. We discuss some methodological advances that have relevance to the issue and applaud the authors for challenging existing dogma.

Public discourse is often caustic and conflict-filled. This trend seems to be particularly evident when the content of such discourse is around moral issues (broadly defined) and when the discourse occurs on social media. Several explanatory mechanisms for such conflict have been explored in recent psychological and social-science literatures. The present work sought to examine a potentially novel explanatory mechanism defined in philosophical literature: Moral Grandstanding. According to philosophical accounts, Moral Grandstanding is the use of moral talk to seek social (...) status. For the present work, we conducted six studies, using two undergraduate samples (Study 1, N = 361; Study 2, N = 356); a sample matched to U.S. norms for age, gender, race, income, Census region (Study 3, N = 1,063); a YouGov sample matched to U.S. demographic norms (Study 4, N = 2,000); and a brief, one-month longitudinal study of Mechanical Turk workers in the U.S. (Study 5, Baseline N = 499, follow-up n = 296), and a large, one-week YouGov sample matched to U.S. demographic norms (Baseline N = 2,519, follow-up n = 1,776). Across studies, we found initial support for the validity of Moral Grandstanding as a construct. Specifically, moral grandstanding motivation was associated with status-seeking personality traits, as well as greater political and moral conflict in daily life. (shrink)

In this paper we address the question of when a researcher is justified in describing his or her artificial agent as demonstrating ethical decision-making. The paper is motivated by the amount of research being done that attempts to imbue artificial agents with expertise in ethical decision-making. It seems clear that computing systems make decisions, in that they make choices between different options; and there is scholarship in philosophy that addresses the distinction between ethical decision-making and general decision-making. Essentially, the qualitative (...) difference between ethical decisions and general decisions is that ethical decisions must be part of the process of developing ethical expertise within an agent. We use this distinction in examining publicity surrounding a particular experiment in which a simulated robot attempted to safeguard simulated humans from falling into a hole. We conclude that any suggestions that this simulated robot was making ethical decisions were misleading. (shrink)

Carruthers has proposed a novel and quite interesting hypothesis for the role of language in conceptual integration, but his treatment does not acknowledge work in cognitive science on metaphor and analogy that reveals how diverse knowledge structures are integrated. We claim that this body of research provides clear evidence that cross-domain conceptual connections cannot be driven by syntactic processes alone.

In June 2020, representatives of eight photography organizations addressed ongoing challenges to the industry by introducing the “Photo Bill of Rights,” asserting “the rights of all lens-based workers and defining actions that build a safer, healthier, more inclusive, and transparent industry.” The bill centers what “lens-based workers” are owed by the media organizations that employ them. This study analyzes the bill’s contents and the explicit and implicit values within it, finding that the bill presents a normative view of the work (...) environment lens-based workers should expect as a baseline. In so doing, the bill connects what lens-based workers owe their respective publics to what their employers owe those same workers. The bill highlights the enabling environment that these workers need to satisfy their obligations to the public. The bill reminds employers of their duty to create an equitable environment that can enable the fulfillment of public responsibility. (shrink)

When people are asked “Do you have the time?” they can answer in a variety of ways, such as “It is almost 3”, “Yeah, it is quarter past two”, or more precisely as in “It is now 1:43”. We present the results of four experiments that examined people’s real-life answers to questions about the time. Our hypothesis, following previous research findings, was that people strive to make their answers optimally relevant for the addressee, which in many cases allows people to (...) give rounded, and not exact, time responses. Moreover, analyses of the non-numeral words, hesitations, and latencies of people’s verbal responses to time questions reveal important insights into the dynamics of speaking to achieve optimal relevance. People include discourse markers, hesitation marks, like “uh” and “um”, and pauses when answering time questions to maximize the cognitive effects (e.g., a rounded answer is adequate) listeners can infer while minimizing the cognitive effort required to infer these effects. This research provides new empirical evidence on how relevance considerations shape collaborative language use. (shrink)

Estimates of unknown quantities are influenced by both self-generated anchors (SGAs) and externally provided anchors (EPAs; e.g., the advice of others). It was hypothesised that people use the degree of similarity between these anchors to render final responses. Thus we tested predictions drawn from metacognitive accounts of anchoring using procedures similar to the traditional anchoring paradigm. In a single experiment we manipulated SGA–EPA similarity, EPA level, and EPA source credibility. Results showed that the relationship between SGA–EPA similarity and the decision (...) weight given to the EPA, relative to the weight given to the SGA, depended on source credibility. Bolstering the metacognitive framework, participants were most confident about their final responses when their SGA was similar to the EPA and the EPA came from a highly credible source. These results support a metacognitive account of the anchoring heuristic. (shrink)

The genetic stability of living cells is continuously threatened by the presence of endogenous reactive oxygen species and other genotoxic molecules. Of particular threat are the thousands of DNA single-strand breaks that arise in each cell, each day, both directly from disintegration of damaged sugars and indirectly from the excision repair of damaged bases. If un-repaired, single-strand breaks can be converted into double-strand breaks during DNA replication, potentially resulting in chromosomal rearrangement and genetic deletion. Consequently, cells have adopted multiple pathways (...) to ensure the rapid and efficient removal of single-strand breaks. A general feature of these pathways appears to be the extensive employment of protein–protein interactions to stimulate both the individual component steps and the overall repair reaction. Our current understanding of DNA single-strand break repair is discussed, and testable models for the architectural coordination of this important process are presented.

In their important paper “Autonomous Agents”, Floridi and Sanders use “levels of abstraction” to argue that computers are or may soon be moral agents. In this paper we use the same levels of abstraction to illuminate differences between human moral agents and computers. In their paper, Floridi and Sanders contributed definitions of autonomy, moral accountability and responsibility, but they have not explored deeply some essential questions that need to be answered by computer scientists who design artificial agents. One such question (...) is, “Can an artificial agent that changes its own programming become so autonomous that the original designer is no longer responsible for the behavior of the artificial agent?” To explore this question, we distinguish between LoA1 (the user view) and LoA2 (the designer view) by exploring the concepts of unmodifiable, modifiable and fully modifiable tables that control artificial agents. We demonstrate that an agent with an unmodifiable table, when viewed at LoA2, distinguishes an artificial agent from a human one. This distinction supports our first counter-claim to Floridi and Sanders, namely, that such an agent is not a moral agent, and the designer bears full responsibility for its behavior. We also demonstrate that even if there is an artificial agent with a fully modifiable table capable of learning* and intentionality* that meets the conditions set by Floridi and Sanders for ascribing moral agency to an artificial agent, the designer retains strong moral responsibility.

This book addresses identity-formation as it relates to social inclusivity. The stigmatized Other have long been marginalized in their social relations with the mainstream. This book reconstitutes the thinking which displaces social exclusiveness, replacing it with new ideas promoting social cohesiveness, reciprocity, and social inclusivity.

ABSTRACT:This manuscript develops the concept of organizational virtue orientation (OVO) and examines differences between family and non-family firms on the six organizational virtue dimensions of Integrity, Empathy, Warmth, Courage, Conscientiousness, and Zeal. Using content analysis of shareholder letters fromS&P 500companies, our analyses find that there are significant differences between family and non-family firms in their espoused OVO, with family firms generally being higher. Specifically, family firms were significantly higher on the dimensions of Empathy, Warmth, and Zeal, but lower on Courage. (...) Based on these findings we further develop the OVO concept through the discussion of implications and areas for future research. (shrink)
