In sexually reproducing organisms maintenance of germ stem cell immortality is fundamental for transmitting genetic material to future generations. While previous research has mainly considered intrinsic regulatory mechanisms in the germline, our recent study has found a direct contribution of somatic cells in preserving germline immortality via the somatically expressed endoribonuclease ENDU‐2 in Caenorhabditis elegans. We have identified ENDU‐2 as a secreted protein that can be taken up by the germline. Here, we discuss how ENDU‐2 might uncouple its RNA‐binding and (...) RNA‐cleavage activities to control gene expression via either an endoribonuclease dependent or an independent way. We also speculate on a possible functional conservation of its mammalian homologs in mediating cell‐cell communication as well as its potential significance in understanding human pathogenesis such as cancer development.

Merleau-Ponty’s essay about Cézanne’s doubt from 1945 is still de- bated. Merleau-Ponty tries to explain the peculiarities of Cézanne’s pictorial lan- guage, for instance his abandonment of the geometrical perspective, as the expression of, what he calls, the “primordial perception”, which is free from the distortions of metaphysical dualism and modern sciences. There are two main problems here. First, primordiality remains an obscure notion, which may be explained by Cézanne’s work, rather than reversely. Secondly, Merleau-Ponty tends to forget that Cézanne’s (...) perception is first of all a painter’s perception, inspired by the idea of what a painting should be and by a conception of the physical performances by which it comes into being. Cézanne tries to liberate painting from the Albertinian idea that a work is like a window, opening a view on a section of reality. Contrary to this, Cézanne stresses the autonomy of the work, its presence as painted – without giving up its contact to the reality depicted. (shrink)

ZusammenfassungDer Beitrag befasst sich mit der Mathematisierung in der praktisch-technischen Ausbildung im letzten Drittel des 18. und ersten Drittel des 19. Jahrhunderts. Anhand von zwei Fällen werden Variantenreichtum und Problemlagen des praktisch-mathematischen Wissens in der Zeit um 1800 herausgearbeitet. Nach einer Einführung zu institutionellem Rahmen und sozialem Status der praktischen Mathematiker (eigentlich mathematischen Praktiker) in den deutschen Gebieten, beschäftigt sich der erste Teil mit dem Bergmeister Johann Andreas Scheidhauer (1718–1784). Die Biographie dieses bislang wenig beachteten Praktikers führt zu einer Analyse (...) seiner Handschriften und deren Rezeption, in erster Linie durch Johann Friedrich Lempe (1757–1801), Professor für Mathematik an der Bergakademie Freiberg. Ein Praktiker der nachfolgenden Generation steht im Fokus des zweiten Teils. Carl Friedrich Steiner (1774–1840) war ein Baumeister im Weimar der Goethezeit. Gewissermaßen reflektiert sein Lehrbuch zur Geometry descriptive die Folgen der fortlaufenden Mathematisierung und den Stellenwert mathematischen Wissens in der Ausbildung junger Praktiker und Künstler. Beide Teilstudien geben Aufschluss zum historischen Verständnis praktischer Mathematik. (shrink)

Notwithstanding the appeal of the “one size fits all” approach that Baumeister et al. propose, we argue that there is no panacea for improving group performance. The concept of “differentiation of selves” constitutes an umbrella term for similar seeming but actually different constructs. Even the same type of “differentiation of selves” can be beneficial for some and harmful for other tasks.

Four studies measured or manipulated beliefs in free will to illuminate how such beliefs are linked to other aspects of personality. Study 1 showed that stronger belief in free will was correlated with more gratitude, greater life satisfaction, lower levels of perceived life stress, a greater sense of self-efficacy, greater perceived meaning in life, higher commitment in relationships, and more willingness to forgive relationship partners. Study 2 showed that the belief in free will was a stronger predictor of life satisfaction, (...) meaning in life, gratitude, and self-efficacy than either locus of control or implicit person theory. Study 3 showed that experimentally manipulating disbelief in free will caused a reduction in the perceived meaningfulness of life. Study 4 found that inducing a stronger belief in free will caused people to set more meaningful goals for themselves. The possible concern that believers in free will simply claim all manner of positive traits was contradicted by predicted null finding.. (shrink)

What makes us human? Why do people think, feel and act as they do? What is the essence of human nature? What is the basic relationship between the individual and society? These questions have fascinated both great thinkers and ordinary humans for centuries. Now, at last, there is a solid basis for answering them, in the form of accumulated efforts and studies by thousands of psychology researchers. We no longer have to rely on navel-gazing and speculation to understand why people (...) are the way they are - we can instead turn to solid, objective findings. This book, by an eminent social psychologist at the peak of his career, not only summarizes what we know about people - it also offers a coherent, easy-to-understand, though radical, explanation. Turning conventional wisdom on its head, the author argues that culture shaped human evolution. Contrary to theories that depict the individual's relation to society as one of victimization, endless malleability, or just a square peg in a round hole, he proposes that the individual human being is designed by nature to be part of society. Moreover, he argues that we need to briefly set aside the endless study of cultural differences to look at what most cultures have in common - because that holds the key to human nature. Culture is in our genes, although cultural differences may not be. This core theme is further developed by a powerful tour through the main dimension of human psychology. What do people want? How do people think? How do emotions operate? How do people behave? And how do they interact with each other? The answers are often surprising, and along the way the author explains how human desire, thought, feeling, and action are connected. (shrink)

Do philosophic views affect job performance? The authors found that possessing a belief in free will predicted better career attitudes and actual job performance. The effect of free will beliefs on job performance indicators were over and above well-established predictors such as conscientiousness, locus of control, and Protestant work ethic. In Study 1, stronger belief in free will corresponded to more positive attitudes about expected career success. In Study 2, job performance was evaluated objectively and independently by a supervisor. Results (...) indicated that employees who espoused free will beliefs were given better work performance evaluations than those who disbelieve in free will, presumably because belief in free will facilitates exerting control over one’s actions.

Four experiments supported the hypothesis that ordinary people understand free will as meaning unconstrained choice, not having a soul. People consistently rated free will as being high unless reduced by internal constraints (i.e., things that impaired people’s mental abilities to make choices) or external constraints (i.e., situations that hampered people’s abilities to choose and act as they desired). Scientific paradigms that have been argued to disprove free will were seen as reducing, but usually not eliminating free will, and the reductions (...) were because of constrained conscious choice. We replicated findings that a minority of people think lacking a soul reduces free will. These reductions in perceived free will were fully explained by reductions in people’s perceived abilities to make conscious decisions. Thus, some people do think you need a soul to have free will—but it is because they think you need a soul to make conscious decisions. (shrink)

What does free will mean to laypersons? The present investigation sought to address this question by identifying how laypersons distinguish between free and unfree actions. We elicited autobiographical narratives in which participants described either free or unfree actions, and the narratives were subsequently subjected to impartial analysis. Results indicate that free actions were associated with reaching goals, high levels of conscious thought and deliberation, positive outcomes, and moral behavior (among other things). These findings suggest that lay conceptions of free will (...) fit well with the view that free will is a form of action control. (shrink)

When making decisions, humans can observe many kinds of information about others' activities, but their effects on performance are not well understood. We investigated social learning strategies using a simple problem-solving task in which participants search a complex space, and each can view and imitate others' solutions. Results showed that participants combined multiple sources of information to guide learning, including payoffs of peers' solutions, popularity of solution elements among peers, similarity of peers' solutions to their own, and relative payoffs from (...) individual exploration. Furthermore, performance was positively associated with imitation rates at both the individual and group levels. When peers' payoffs were hidden, popularity and similarity biases reversed, participants searched more broadly and randomly, and both quality and equity of exploration suffered. We conclude that when peers' solutions can be effectively compared, imitation does not simply permit scrounging, but it can also facilitate propagation of good solutions for further cumulative exploration.

Our recent work suggests that (1) the purpose of human conscious thought is participation in social and cultural groups, and (2) logical reasoning depends on conscious thought. These mesh well with the argument theory of reasoning. In broader context, the distinctively human traits are adaptations for culture and inner processes serve interpersonal functions.

Expert opinions have yielded a wide and controversial assortment of conceptions of free will, but laypersons seem to associate free will more simply with making choices. We found that the more strongly people believed in free will, the more they liked making choices, the higher they rated their ability to make decisions (Study 1), the less difficult they perceived making decisions, and the more satisfied they were with their decisions (Study 2). High free will belief was also associated with more (...) spontaneous associating of choice with freedom, and with the perception of actions as choices. Recalling choices (Study 3) and making choices (Study 4) led to a stronger endorsement of the belief in free will, with an additional effect for the level of choice involved. These findings suggest that the everyday social reality of beliefs about free will is a matter of how people think and feel about choice. (shrink)

For courses in Business Ethics A fresh approach to the assumptions that underlie business practices Two recent events — the 2008 economic meltdown and the ongoing concentration of the nation's wealth in the hands of a very small percentage of the population — have led many people to question a number of basic assumptions about business, corporations, and the workings of contemporary free-market capitalism in a global economy. Written as a dialogue between Socrates and a hypothetical contemporary CEO,Socrates Comes to (...) Wall Street leads students to think critically about perspectives and practices that are taken as “givens” in most American business schools and corporations. Employing this original and provocative approach, author Thomas White seeks to encourage the next generation of business leaders to be more astute about the implications of their actions, and to act more prudently and more fairly than we have seen in the recent past.

Some actions are freer than others, and the difference is palpably important in terms of inner process, subjective perception, and social consequences. Psychology can study the difference between freer and less free actions without making dubious metaphysical commitments. Human evolution seems to have created a relatively new, more complex form of action control that corresponds to popular notions of free will. It is marked by self-control and rational choice, both of which are highly adaptive, especially for functioning within culture. The (...) processes that create these forms of free will may be biologically costly and therefore are only used occasionally, so that people are likely to remain only incompletely self-disciplined, virtuous, and rational.

This interdisciplinary volume questions one of the most fundamental tenets of social theory by focusing on detachment, an important but neglected aspect of social life. Going against the grain of recent theoretical celebrations of engagement, this book challenges us to re-think the relational basis of social theory. In so, doing it brings to light the productive aspects of disconnection, distance and detachment. Rather than treating detachment simply as the moral inversion of compassion and engagement, the volume brings together empirical studies (...) and theoretical comments by leading anthropologists, sociologists and science studies scholars. Taken together, these illustrate the range of contexts within which distance and disconnection can offer meaningful frameworks for action. Positioned at the cutting edge of social theory, this landmark volume will be of great interest to students and academics across the social sciences and humanities. (shrink)
