An Intricate Dance: Life Experience,Multisystem Resiliency,and Rate of Telomere Decline Throughout the Lifespan

Accumulation of life stressors predicts accelerated development and progression of diseases of aging. Telomere length, the DNA‐based biomarker indicating cellular aging, is a mechanism of disease development, and is shortened in a dose response fashion by duration and severity of life stressor exposures. Telomere length captures the interplay between genetics, life experiences and psychosocial and behavioral factors. Over the past several years, psychological stress resilience, healthy lifestyle factors, and social connections have been associated with longer telomere length and it appears that these factors can protect individuals from stress‐induced telomere shortening. In the current review, we highlight these findings, and illustrate that combining these ‘multisystem resiliency’ factors may strengthen our understanding of aging, as these powerful factors are often neglected in studies of aging. In naturalistic studies, the effects of chronic stress exposure on biological pathways are rarely main effects, but rather a complex interplay between adversity and resiliency factors. We suggest that chronic stress effects can be best understood by directly testing if the deleterious effects of stress on biological aging processes, in this case the cell allostasis measure of telomere shortening, are mitigated in individuals with high levels of multisystem resiliency. Without attending to such interactions, stress effects are often masked and missed. Taking account of the cluster of positive buffering factors that operate across the lifespan will take us a step further in understanding healthy aging. While these ideas are applied to the telomere length literature for illustration, the concept of multisystem resiliency might apply to aging broadly, from cellular to systemic health.     

Key Accounts and Team Selling: A Review,Framework, and Research Agenda

As sales organizations increase their reliance on sales teams, they must learn how organizational and interpersonal relationships influence sales teams, how sales teams play a learning role for organizations, and what makes sales teams effective. Presenting a model of interrelationships among members of the selling firm and between the selling and buying firms, we identify five key team selling relationships between (1) members of the same team, (2) members of different teams within the firm, (3) the selling team and the buying center, (4) the selling team and other groups in the selling firm, and (5) the selling team and the firm’s strategy. This model leads to a conceptual framework highlighting relationship drivers, factors, and outcomes instrumental to team selling success. After presenting propositions for future research, theoretical and methodological suggestions are included to facilitate research in this area. We conclude with perspectives on the future of research and practice in key accounts and team selling.     

The Need for Speed: Agility Selling

In turbulent business times, organizations have sought to become more agile. Organizational agility has been asserted to require workforce agility, but thus far, little focus has been given to workers. Traditionally, salespeople have sought ways to differentiate themselves and create advantage for customers. This paper asserts that, in order to continue this tradition of differentiation and advantage, salespeople must engage in agility thinking. Agility has been studied as it applies to manufacturing processes and other firm activities. Agile salespeople have a mental dexterity at the point of customer contact. They are quick to observe opportunities and are able to anticipate customers’ ever-changing needs, wants, and preferences. This paper presents a framework for agility selling, applying concepts from the agility manufacturing literature and proffering distinct characteristics of sales force agility.     

Perceived,not actual,similarity predicts initial attraction in a live romantic context: Evidence from the speed‐dating paradigm

The “similarity‐attraction” effect stands as one of the most well‐known findings in social psychology. However, some research contends that perceived but not actual similarity influences attraction. The current study is the first to examine the effects of actual and perceived similarity simultaneously during a face‐to‐face initial romantic encounter. Participants attending a speed‐dating event interacted with ～12 members of the opposite sex for 4 min each. Actual and perceived similarity for each pair were calculated from questionnaire responses assessed before the event and after each date. Data revealed that perceived, but not actual, similarity significantly predicted romantic liking in this speed‐dating context. Furthermore, perceived similarity was a far weaker predictor of attraction when assessed using specific traits rather than generally.     

Beyond Data Collection: Ethical Issues in Minority Research

This article examines ethical concerns surrounding research on minority issues. Specifically, it addresses whether researchers have an obligation to consider (a) the impact that minority research can have on vulnerable populations and (b) their own backgrounds before conducting or assessing minority research for publication. The article argues for such an obligation mainly from a consequentialist perspective and then explores possible strategies for assessing and meeting that obligation. Finally, it explores the possible negative secondary effects of those strategies and censorship concerns.     

Comparing Online Adjustments to Distance and Direction in Fast Pointing Movements

It has been suggested that movements are planned in terms of direction and distance. If so, online adjustments to changes in the direction and distance of the movements may also differ. The authors therefore investigated whether fast online movement adjustments are the same for perturbations of the direction and of the distance. While subjects made fast pointing movements, the authors perturbed either target direction or distance or both shortly after movement initiation. Both kinds of perturbations resulted in accurate online adjustments. The latency and intensity of corrections for distance and direction perturbations were quite similar. This suggests that there might be one mechanism controlling both distance and direction perturbations.     

Generalized Schedule Following in a Youth with Autism

Abstract

Photographic activity schedules were used to increase on-task behaviour in a youth with autism. The multiple probe design included baseline, training, tests for training effects, resequencing of photographs, generalization to new photographs, and maintenance. The results showed that the participant was able to carry out four different chains (photographic activity schedules) without any prompts from the staff, even when the photographs were resequenced, and new photographs were included. On the other hand, there was no reduction of training trials to reach criterion from the first to the fourth chain. The results are discussed with reference to different aspects of generalization.     

Color Illusion

As standardly conceived, an illusion is an experience of an object o appearing F where o is not in fact F. Paradigm examples of color illusion, however, do not fit this pattern. A diagnosis of this uncovers different sense of appearance talk that is the basis of a dilemma for the standard conception. The dilemma is only a challenge. But if the challenge cannot be met, then any conception of experience, such as representationalism, that is committed to the standard conception is false. Perhaps surprisingly, naïve realism provides a better account of color illusion.
