These essays are fundamentally a credo and partly a manifesto. The author identifies problems in the college teaching of the Humanities, and after description, analysis, and illustration, he makes brief recommendations. He uses "Humanities" to englobe Philosophy and Religion, and largely neglects the fine and performing arts. Throughout, his emphasis is on reading skills. The sections are numbered through six chapters and a Prologue, implying one unfolding argument, which is largely the case.

This brilliant and provocative study centers on the philosophical bases of style, and especially the use of metaphor in narrative fiction. Wicker has taken as his premise the importance of the polarization of language between metaphor and analogy; in his first section on the nature of metaphor, he argues for a balance or "marriage" of the two. He observes that since the Renaissance the Thomistic sense of analogy was lost and not replaced. Wicker’s two basic assumptions about metaphor are that (...) it is endemic in language, and that it is never innocent: it always implies a subterranean metaphysic. The first half of this book is devoted to exploring the implications of these two points; chapters relating metaphor to analogy, to fiction, to nature, and to God form the theoretical basis for the second half, a systematic application of these preliminary developments.

Three experiments explore the role of working memory in motor skill acquisition and performance. Traditional theories postulate that skill acquisition proceeds through stages of knowing, which are initially declarative but later procedural. The reported experiments challenge that view and support an independent, parallel processing model, which predicts that procedural and declarative knowledge can be acquired separately and that the former does not depend on the availability of working memory, whereas, the latter does. The behaviour of these two processes was manipulated (...) by providing or withholding visual (and auditory) appraisal of outcome feedback. Withholding feedback was predicted to inhibit the use of working memory to appraise success and, thus, prevent the formation of declarative knowledge without affecting the accumulation of procedural knowledge. While the first experiment failed to support these predictions, the second and third experiments demonstrated that procedural and declarative knowledge can be acquired independently. It is suggested that the availability of working memory is crucial to motor performance only when the learner has come to rely on its use. (shrink)

This paper responds to the recent situationist critique of practical rationality and decision-making. According to that critique, empirical evidence indicates that our choices are governed by morally irrelevant situational factors and not durable character traits, and rarely result from overt rational deliberation. This critique is taken to indicate that popular moral theories in the Western tradition are descriptively deficient, even if normatively plausible or desirable. But we believe that the situationist findings regarding the sources of, or influences over, our moral (...) agency do not reflect durable features of human nature, and claim that these findings are a byproduct of a deficient approach to moral education. Existing models of moral education, which are “positive” in nature, do a poor job of developing virtuous people. Instead, we argue that a “negative” approach to moral education, traceable to Locke, Smith, and Rousseau, would be more successful. This strategy represents something of a compromise between the strategies adopted by thinkers like Rachana Kamtekar : 458–491 2004), who argues that traditional moral categories escape largely untouched by findings in social psychology, and John Doris :504–530 1998) and Gilbert Harman : 87–94 2003), who argue that findings in psychology prove our traditional moral theories are defective.

The metabolic organization of both normal and malignant prostate cellular phenotypes involves some unusual and surprising features. In particular, both conditions exhibit ratios of NADH/NAD+ and NADPH/NADP+ charactersitic of high oxidative states despite a chronic shortage of O2 in both conditions. In this paper, we observe that, in prostate cancer cells, the oxidizing power of the fatty acid synthesis (FAS) pathway is so large that redox is stabilized more favorably (more oxidized) than in normal prostate cells. This FAS‐facilitated redox improvement (...) occurs despite the fact that malignant cells are more O2 limited and therefore express more hypoxia inducible factor 1 (HIF1) and express hypoxia‐regulated genes more robustly. This unusual metabolic situation clearly separates direct regulatory effects of redox balance from secondary effects of hypoxia per se. The physiological significance of the FAS pathway is thus the harnessing of its oxidizing power for improving redox balance despite conditions of more extreme hypoxia. Similar hypoxia defense strategies are found in animal species that are unusually tolerant to oxygen lack. Our hypothesis is that the metabolic organization in the “low zinc, low citrate” phenotype reflects an hypoxia‐defense adaptation geared toward redox balance, with prostate cancer cells being relatively more oxidized, even if more hypoxic, than normal prostate cells. Recognition and understanding of these redox balancing and hypoxia defense functions may lead to new intervention strategies by developing new intracellular targets for prostate cancer therapy.

We isolate two abstract determinacy theorems for games of length $\omega_1$ from work of Neeman and use them to conclude, from large-cardinal assumptions and an iterability hypothesis in the region of measurable Woodin cardinals thatif the Continuum Hypothesis holds, then all games of length $\omega_1$ which are provably $\Delta_1$ -definable from a universally Baire parameter are determined;all games of length $\omega_1$ with payoff constructible relative to the play are determined; andif the Continuum Hypothesis holds, then there is a model of (...) ${\mathsf{ZFC}}$ containing all reals in which all games of length $\omega_1$ definable from real and ordinal parameters are determined.

Although there is much research on the relationships of corporate social responsibility and employee-related outcomes, a systematic and quantitative integration of research findings is needed to substantiate and broaden our knowledge. A meta-analysis allows the comparison of the relations of different types of CSR on several different outcomes, for example to learn what type of CSR is most important to employees. From a theoretical perspective, social identity theory is the most prominent theoretical approach in CSR research, so we aim to (...) investigate identification as a mediator of the relationship between CSR and employee-related outcomes in a meta-analytical mediation model. This meta-analysis synthesizes research findings on the relationship between employees' perception of CSR (people, planet, and profit) and employee-related outcomes (identification, engagement, organizational attractiveness, turnover (intentions), OCB, commitment, and job satisfaction), thereby distinguishing attitudes and behavior. A total of 143 studies (N= 89,396) were included in the meta-analysis which was conducted according to the methods by Schmidt and Hunter (except of the meta-analytical structural equation model). Mean effect sizes for the relationship between CSR and employee-related attitudes and behaviors were medium-sized to large. For attitudes, the relationships were stronger than for behavior. For specific types of CSR, average effect sizes were large. Identification mediated the relation between CSR and commitment, job satisfaction, and OCB, respectively. Based on our results, we give recommendations concerning the design of CSR initiatives in a way that benefits employees. (shrink)

Early versions of satellite and radiosonde datasets suggested that the tropical surface had warmed more than the troposphere, while climate models consistently showed tropospheric amplification of surface warming in response to human-caused increases in greenhouse gases. We revisit such comparisons here using new observational estimates of surface and tropospheric temperature changes. We find that there is no longer a serious discrepancy between modeled and observed trends in the tropics. Our results contradict a recent claim that all simulated temperature trends in (...) the tropical troposphere are inconsistent with observations. This claim was based on the use of older radiosonde and satellite datasets and on two methodological errors: the neglect of observational trend uncertainties introduced by interannual climate variability and application of an inappropriate statistical “consistency test”.This emerging reconciliation of models and observations has two primary explanations. First, because of changes in the treatment of buoy and satellite information, new surface temperature datasets yield slightly reduced tropical warming relative to earlier versions. Second, recently developed satellite and radiosonde datasets now show larger warming of the tropical lower troposphere. In the case of a new satellite dataset from remote sensing systems, enhancedRSS warming is due to an improved procedure of adjusting for inter-satellite biases. When the RSS-derived tropospheric temperature trend is compared with four different observed estimates of surface temperature change, the surface warming is invariably amplified in the tropical troposphere, consistent with model results. Even if we use data from a second satellite dataset with smaller tropospheric warming than in remote sensing systems RSS, observed tropical lapse rates are not significantly different from those in all model simulations.Our results contradict a recent claim that all simulated temperature trends in the tropical troposphere and in tropical lapse rates are inconsistent with observations. This claim was based on the use of older radiosonde and satellite datasets and on two methodological errors: the neglect of observational trend uncertainties introduced by interannual climate variability and application of an inappropriate statistical “consistency test”.
