Across the Martian Frontier? Thoughts on Planet B,a Martian Safety Valve,and the Earth as Our Body

Even though we are on the precipice of a “bad Anthropocene,” humankind should not colonize Mars. Mars is often depicted as our “Planet B”—an evacuation plan for Earth. But in this time of ecological crisis, theologian Sallie McFague suggests that we think of the Earth as God’s body and take our obligation to care for our common home seriously. Likewise, in contrast to calls for colonization, I contend that two American historical anecdotes—the safety valve theory and the Yellowstone—illustrate why humanity should think less about becoming Martians and instead find meaning and purpose in remaining Earthlings.     

ON THE ANALYST'S IDENTIFICATION WITH THE PATIENT: THE CASE OF J.‐B. PONTALIS AND G. PEREC

The writer Georges Perec was in psychoanalysis with Jean‐Bertrand Pontalis for four years in the early 1970s. In this essay, the author presents the exceptional interest this analyst took in this patient and the ways in which that interest manifested itself in his work, psychoanalytic and otherwise. Many correlative factors suggest that identificatory processes persisted beyond the treatment and were maintained into Pontalis's later life. While this paper is primarily intended to provide evidence to support this view of a specific case, the author closes by reflecting that this may be a more general phenomenon and the reasons for this.     

The Other Shoe: An Early Operant Conditioning Chamber for Pigeons

We describe an early operant conditioning chamber fabricated by Harvard University instrument maker Ralph Gerbrands and shipped to Japan in 1952 in response to a request of Professor B. F. Skinner by Japanese psychologists. It is a rare example, perhaps the earliest still physically existing, of such a chamber for use with pigeons. Although the overall structure and many of the components are similar to contemporary pigeon chambers, several differences are noted and contrasted to evolutionary changes in this most important laboratory tool in the experimental analysis of behavior. The chamber also is testimony to the early internationalization of behavior analysis.     

Attentional Predictors of 5‐month‐olds' Performance on a Looking A‐not‐B Task

In the first year of life, the ability to search for hidden objects is an indicator of object permanence and, when multiple locations are involved, executive function (i.e. inhibition, cognitive flexibility and working memory). The current study was designed to examine attentional predictors of search in 5‐month‐old infants (as measured by the looking A‐not‐B task), and whether levels of maternal education moderated the effect of the predictors. Specifically, in a separate task, the infants were shown a unique puppet, and we measured the percentage of time attending to the puppet, as well as the length of the longest look (i.e., peak fixation) directed towards the puppet. Across the entire sample (N = 390), the percentage of time attending to the puppet was positively related to performance on the visual A‐not‐B task. However, for infants whose mothers had not completed college, having a shorter peak looking time (after controlling for percentage of time) was also a predictor of visual A‐not‐B performance. The role of attention, peak fixation and maternal education in visual search is discussed. Copyright © 2015 John Wiley & Sons, Ltd.     

难治性丙型肝炎研究新进展

随着聚乙二醇化干扰素（IFN）的普及应用和慢性丙型肝炎规范化治疗的开展,其治愈率不断提高.但疗效不佳的慢性丙型肝炎患者不断积累,难治性慢性丙型肝炎患者成为临床医生必须面对的挑战.难治性丙型肝炎患者应当分为两类,第一类为“难治疗”性慢性丙型肝炎患者,该类患者由于宿主条件限制,不能耐受IFN联合利巴韦林（RBV）的标准治疗,如儿童和老年人、慢性肾功能衰竭患者等.第二类为“难治愈”性慢性丙型肝炎患者,该类患者可以耐受标准治疗方案,但按照应答指导的治疗原则（RGT）治疗后,效果仍然不佳或复发.本文就近年关于难治性丙型肝炎的研究进展,从难治性丙型肝炎的定义、机制、治疗诸方面作一综述.     

Differential cerebral involvement in the cognitive functioning of bilinguals

The cognitive processing strategies of two groups of French-English bilinguals were studied by means of an auditory Stroop test designed to evaluate cerebral hemispheric involvement. An “early bilingual” group were bilingual before the age of 5, and a “late bilingual” group were bilingual after the age of 10. Stimuli were words uttered in pitches that were related to word meanings either congruently (as in the word “high” uttered in a high pitch) or incongruently (the word “haute” uttered in a low pitch). In one condition, subjects were to differentiate low from high pitches, disregarding meaning, while in a second condition, they were to disregard pitch and respond to word meanings. Measures of field independence were also taken. Results of data analyses suggest that male early bilinguals—the most field independent subgroup—process meaning efficiently in both cerebral hemispheres, but process pitch better in the right hemisphere. However, male late bilinguals and female bilinguals, both early and late, process meaning more rapidly in the right cerebral hemisphere and pitch equally rapidly in both hemispheres. The findings are interpreted as reflecting hemisphere-based strategy and sex differences in information-processing by the two bilingual groups.     

Personality,age, and fluid intelligence

A total of 383 participants (aged 19 to 66 years) completed the Raven's Progressive Matrices, the Myers‐Briggs Type Indicator (MBTI), the Fundamental Interpersonal Relations Orientation‐Behavior (FIRO‐B), and the California Psychological Inventory‐434 (CPI‐434). Results showed that IQ was positively correlated with perceiving (MBTI), control (FIRO‐B), intellectual efficiency (CPI‐434), achievement via independence (CPI‐434), and negatively correlated with sensing (MBTI), internality (CPI‐434) and norm‐favouring (CPI‐434), supporting the majority of the hypotheses. Participants' age was correlated with many measures, particularly intelligence and accounted for a third of the variance in IQ scores. Limitations are considered.     

B. F. Skinner and G. H. Mead: on biological science and social science.

Skinner's contributions to psychology provide a unique bridge between psychology conceptualized as a biological science and psychology conceptualized as a social science. Skinner focused on behavior as a naturally occurring biological phenomenon of interest in its own right, functionally related to surrounding events and, in particular (like phylogenesis), subject to selection by its consequences. This essentially biological orientation was further enhanced by Skinner's emphasis on the empirical foundations provided by laboratory-based experimental analyses of behavior, often with nonhuman subjects. Skinner's theoretical writings, however, also have affinity with the traditions of constructionist social science. The verbal behavior of humans is said to be subject, like other behavior, to functional analyses in terms of its environment, in this case its social context. Verbal behavior in turn makes it possible for us to relate to private events, a process that ultimately allows for the development of consciousness, which is thus said to be a social product. Such ideas make contact with aspects of G. H. Mead's social behaviorism and, perhaps of more contemporary impact in psychology, L. Vygotsky's general genetic law of cultural development. Failure to articulate both the biological and the social science aspects of Skinner's theoretical approach to psychology does a disservice to his unique contribution to a discipline that remains fragmented between two intellectual traditions.
