The “Ages” of Ogden Nash

This essay looks at the way Ogden Nash, America's Genius of Light Verse, saw his life and times in the 30's, 40's, and 50's. It focuses on a group of poems in which the author mentions his age at the time of writing and explores their insights. They move from young adulthood to retirement and thus become Nash's equivalent of Shakespeare's Ages of Humanity. The author notes how his study of Nash has provided insights in living and illustrates this through poems of his own. In following this particular journey through the stages of life, we might well discover ways of mining the gold in our own experience.     

Relative Importance and Utility of Positive Worker States: A Review and Empirical Examination

Our purpose was to identity the unique contribution, relative importance, and utility of positive worker states. Using Luthans et al.'s (2007) five positive organizational behavior criteria, a variety of positive worker states were reviewed and then empirically tested to establish if they met these criteria. Data were collected from 724 restaurant employees. Positive worker states included: job involvement, perceived organizational support, engagement, and vigor. Criteria were self-reported performance, customer service, turnover intention, satisfaction, and quality of life. Our review indicated consistency between predictor adequacy of meeting the criteria and their empirical relationship with key outcomes. This research found the positive worker states to be independent constructs that had differential effects depending on the focused outcome. Regression and relative weights analyses showed involvement was a weak predictor of outcomes, while perceived organizational support was the most consistent predictor. Vigor was most useful when predicting job performance. Quality of life was poorly explained.     

Analyzing the Dynamics of Affective Dyadic Interactions Using Patterns of Intra- and Interindividual Variability

There are many compelling accounts of the ways in which the emotions of 1 member of a romantic relationship should influence and be influenced by the partner. However, there are relatively few methodological tools available for representing the alleged complexity of dyad level emotional experiences. In this article, we present an algorithm for examining such affective dynamics based on patterns of variability. The algorithm identifies periods of stability based on length of time and amplitude of emotional fluctuations. The patterns of variability and stability are quantified at the individual and dyadic level, and the approach is illustrated using data of the daily emotional experiences of individuals in romantic couples. With this technique, we examine the fluctuations of the emotions for each person and inspect the overlap fluctuations between both individuals in the dyad. The individual and dyadic indices of variability are then used to predict the status of the dyads (i.e., together, apart) 1 year later.     

White matter maturation supports the development of reasoning ability through its influence on processing speed

The structure of the human brain changes in several ways throughout childhood and adolescence. Perhaps the most salient of these changes is the strengthening of white matter tracts that enable distal brain regions to communicate with one another more quickly and efficiently. Here, we sought to understand whether and how white matter changes contribute to improved reasoning ability over development. In particular, we sought to understand whether previously reported relationships between white matter microstructure and reasoning are mediated by processing speed. To this end, we analyzed diffusion tensor imaging data as well as data from standard psychometric tests of cognitive abilities from 103 individuals between the ages of 6 and 18. We used structural equation modeling to investigate the network of relationships between brain and behavior variables. Our analyses provide support for the hypothesis that white matter maturation (as indexed either by microstructural organization or volume) supports improved processing speed, which, in turn, supports improved reasoning ability.     

Stimulus equivalence and arbitrarily applicable relational responding.

Subjects' responses to nonarbitrary stimulus relations of sameness, oppositeness, or difference were brought under contextual control. In the presence of the SAME context, selecting the same comparison as the sample was reinforced. In the presence of the OPPOSITE context, selecting a comparison as far from the sample as possible on the physical dimension defined by the set of comparisons was reinforced. Given the DIFFERENT context, selecting any comparison other than the sample was reinforced. Subjects were then exposed to arbitrary matching-to-sample training in the presence of these same contextual cues. Some subjects received training using the SAME and OPPOSITE contexts, others received SAME and DIFFERENT, and others received SAME, OPPOSITE, and DIFFERENT. The stimulus networks established allowed testing for a wide variety of derived relations. In two experiments it was shown that derived performances were consistent with relational responding brought to bear by the contextual cues. In contexts relevant to the relation of sameness, stimulus equivalence emerged. Other kinds of relational networks emerged in the other contexts. Arbitrarily applicable relational responding may give rise to a very wide variety of derived stimulus relations. The kinds of performances seen in stimulus equivalence do not appear to be unique.     

Testimony as Evidence: More Problems for Linear Pooling

This paper considers a special case of belief updating??when an agent learns testimonial data, or in other words, the beliefs of others on some issue. The interest in this case is twofold: (1) the linear averaging method for updating on testimony is somewhat popular in epistemology circles, and it is important to assess its normative acceptability, and (2) this facilitates a more general investigation of what it means/requires for an updating method to have a suitable Bayesian representation (taken here as the normative standard). The paper initially defends linear averaging against Bayesian-compatibility concerns raised by Bradley (Soc Choice Welf 29:609?C632, 2007), as well as problems associated with multiple testimony updates. The resolution of these issues, however, requires an extremely nuanced interpretation of the parameters of the linear averaging model??the so-called weights of respect. We go on to propose a role that the parameters of any ??shortcut?? updating function should play, by way of minimal interpretation of these parameters. The class of updating functions that is consistent with this role, however, excludes linear averaging, at least in its standard form.     

WHEN THINKING HESITATES: PHILOSOPHY AS PROSTHESIS AND TRANSFORMATIVE VISION

In this essay, I draw on Henri Bergson and Maurice Merleau‐Ponty to interrogate what philosophy is and how it can continue to think. Though my answer is not reducible to the views of either philosopher, what joins them is an attempt to elaborate philosophy as a different way of seeing. In this light, I propose a view of philosophy as prosthesis—as a means and a way for seeing differently. Rather than a simple tool, philosophy as prosthesis is a transformative supplement, one that our bodily perception calls for and wherein that perception is recast. Rather than a fixed or assured view, this prosthesis holds open the interval in which thinking can take place. Philosophy, I argue, must wait. It sees and thinks hesitatingly, for the temporality it inscribes is not a foreseeable development but the unfolding of life as tendency, as that which creates its own possibility as it comes into existence.     

Maternal perceptions of the infant: Relationship to maternal self‐efficacy during the first six weeks' postpartum

Mothers' perceptions of their infants and their own levels of self‐efficacy contribute to developing maternal‐infant attunement. The purpose of this investigation was to examine the associations between maternal perceptions of their own infants relative to other infants and maternal self‐efficacy in a group of ethnically diverse, low‐income, first‐time mothers during the first six weeks postpartum. By employing a structural equation model approach, we explored relationships between the predictor (maternal neonatal perceptions) and dependent variable (maternal self‐efficacy). Changes in maternal perceptions of their own infants significantly contributed to self‐reported levels of self‐efficacy while controlling for concurrent self‐esteem. Maternal perceptions of her infant as less difficult than the average infant at six weeks postpartum predicted increased levels of maternal self‐reported self‐efficacy. The present study supports further exploration of the first six weeks postpartum as a sensitive period for targeting intervention and support, particularly for mothers and infants at highest risk.
