Chronically stressed female rats show increased anxiety but no behavioral alterations in object recognition or placement memory: a preliminary examination

Stress, depending on intensity and duration, elicits adaptive or maladaptive physiological effects. Increasing evidence shows those patterns of advantageous versus deleterious physiologic stress effects also exist for some brain functions, including learning and memory. For example, short stress enhances, while chronic stress impairs, performance on numerous cognitive tasks in male rats. In contrast, performance of female rats is enhanced, or not altered, following both short-term and long-term stress exposure on the same behavioral tasks. The current study was designed to better characterize the behavioral effects of sustained chronic restraint stress in female rats. Female Sprague Dawley rats were assigned to a stress (restraint, 6 h/day, 35 days) or control (no stress) condition, weighed weekly, and then tested on open field (OF), object recognition (OR) and object placement (OP) tasks. Stressed females gained less weight during stress than controls. On the OF, there were no group differences in locomotor activity, but stressed females made fewer inner visits than controls, indicating increased anxiety. Both groups successfully performed the OP and OR tasks across all inter-trial delays, indicating intact non-spatial and spatial memory in both control and stress females. The current results provide preliminary evidence that the commonly used chronic restraint stress model may not be an efficient stressor to female rats.     

The Good Immigrant Worker: 2013 US Senate Bill 744, Color-Blind Nativism and the Struggle for Comprehensive Immigration Reform

We explore immigration politics in the contemporary USA through analysis of the political framing of 2013 US Senate Bill 744, especially among its supporters. SB 744 is a bipartisan comprehensive immigration reform proposal that called for the largest overhaul of the immigration system in more than 25 years; it was passed in June 2013 by the US Senate but blocked in the House. Through analysis of the 2012–2013 textual content of the official websites and blogs of six US immigration lobby organizations from across the political spectrum, we offer a typology of political framings of comprehensive immigration reform. Drawing on popular anti-immigrant rhetoric, organizations with an agenda of immigration restriction and deterrence battled against the bill. On the other side, supporters of the bill ranged from business coalitions to immigrant rights groups, an assortment of interests that was reflected in the variety of arguments advanced in favor of the bill. Despite the far more fragmented character of pro-SB 744 discourse in comparison to that advanced by the opposition, our investigation suggests the ongoing and contested formation of a strategic pro-SB 744 framing that centered on the “good immigrant worker,” a “race-blind” trope that melds US nationalist narratives of immigration with an ethos of neoliberalism that upholds individual merit and market value to create a notion of “deservingness” that affirms the worth of immigrants as diligent workers.     

Incremental validity of mindfulness-based attention in relation to the concurrent prediction of anxiety and depressive symptomatology and perceptions of health

This investigation evaluated the role of mindfulness-based attention in concurrently predicting anxiety and depressive symptomatology and perceived health functioning in a community sample of 170 young adults (95 females; mean age (Mage) = 22.2 years, SD = 7.6). Partially consistent with prediction, results indicated that, relative to negative and positive affectivity and emotional expression and processing associated with approach-oriented coping, mindfulness-based attention incrementally predicted anhedonic depressive, but not anxious arousal, symptoms. Additionally, consistent with prediction, mindfulness-based attention demonstrated incremental validity in relation to perceived health, and the degree of impairment of health in terms of physical and mental functioning. Results are discussed in relation to the construct development of mindfulness-based attention, and specifically, the role(s) of this factor in emotional and physical health processes.     

Determination of problems in patients with post‐laryngectomy

The purpose of this study is the determination of the physical and psychosocial problems of total and partial laryngectomies. A total of 25 patients, who were operated with the diagnosis of larynx carcinoma in 2010 at Gazi University Faculty of Medicine Otolaryngology Department, were included in the study. They were evaluated with the help of the Personal Information Form (PIF) and the Determination Form of Post Laryngectomy Problem (DFPLP) for the problems they encountered after the operation. Total laryngectomy (TL) was performed on 76% of patients. It was determined that patients undergoing total laryngectomy experienced some physical and psycho‐social problems such as problems in sleep (31.6%), smell (52.6%), taste (36.8%), and difficulty in swallowing solid foods (36.8%). Furthermore in patients with TL surgery whilst 47.4% of them think that their sexual lives were affected rather negatively, this rate was determined as 33.3% in patients with partial laryngectomy surgery (PL). The psychosocial score averages of the patients who had smell and taste disorders were significantly lower (p < 0.05). The patients, who underwent a laryngectomy operation, experienced many physical, social, and psychological problems. Thus, medical personnel also need to pay attention to these concomitant problems that occur during the treatment of the primary disease and the application of necessary supplementary treatments such as voice prosthesis, pre‐op and post‐op counseling, and anti‐depressants seems significant in terms of increasing the life quality of the patients.     

Anticipating the Societal Challenges of Nanotechnologies

“In this article we sketch out the landscape for this Special Issue on anticipating and embedding the societal challenge of nanotechnologies. Tools that actors may choose to employ for these processes are articulated, and further explored through the introduction of the seven articles which comprise this Issue. Taken together, these articles create a cogent narrative on the societal challenges posed by nanotechnologies. They are drawn together by three distinct themes, each of which is briefly considered within this context of this Introductory article”.     

Cognitive flexibility in hypnosis: response to change communication from the hypnotist.

It was predicted that modification of response as it indexes cognitive flexibility in the hypnotic subject is related to susceptibility to hypnosis and the difficulty of the hypnotic task attempted. Experiment 1 isolated two distinct hypnotic tasks (easy and difficult); alternative forms of each item conveyed either clear or unclear structure concerning the response that was perceived as most appropriate. In Experiment 2, 101 subjects were administered hypnotic induction procedures and tested for modification of response on both items; for each subject, the hypnotist posed a conflict in communication by plausibly requesting an alteration in response from the behavior that the subject had chosen to indicate previously. Change data demonstrated that hypnotic subjects modified their behavior in hypnosis, but their cognitive flexibility was much more relevant to easy than to difficult tasks. Results highlight a further dimension of role enactment as well as the special role cognitive skills in play in our understanding of performance on hypnotic test items.
