Friendship Work on Facebook: Young Adults' Understandings and Practices of Friendship

Young adults use social networking sites (SNSs) such as Facebook to engage as friends, yet there has been little systematic research that has investigated their sense‐making of friendship in relation to their uses of Facebook, as well as how Facebook as a socio‐technical system interacts with their friendship practices. Twelve friendship discussion groups were conducted in urban and non‐urban New Zealand, with 26 women and 25 men aged 18–25 years, in same and mixed‐gender groups. Our social constructionist thematic analysis showed the young adults made sense of friendship through themes of ‘fun times together’, an ‘investment’, ‘protection’ and ‘self‐authenticity’, and these meanings were enacted in particular ways within Facebook. This SNS was used primarily for enjoying friendship and ‘investing in’ friendships, and friendship protection was required to maintain friends' online privacy. Facebook provided a way to demonstrate self‐authenticity within friendship relationships through censored ‘show off’ self‐displays and favoured friendship activities. Facebook supported, disrupted and modified these particular friendship understandings by broadening the audience for friendship actions and intensifying friends' responses through 24/7 accessibility and instantaneous activity notifications. These interactions between friendship understandings and Facebook as a socio‐technical system demonstrate how friendship was reinforced, negotiated and re‐worked through this online context.

Dissociable effects of basolateral amygdala lesions on decision making biases in rats when loss or gain is emphasized

Individuals switch from risk seeking to risk aversion when mathematically identical options are described in terms of loss versus gains, as exemplified in the reflection and framing effects. Determining the neurobiology underlying such cognitive biases could inform our understanding of decision making in health and disease. Although reports vary, data using human subjects have implicated the amygdala in such biases. Animal models enable more detailed investigation of neurobiological mechanisms. We therefore tested whether basolateral amygdala (BLA) lesions would affect risk preference for gains or losses in rats. Choices in both paradigms were always between options of equal expected value—a guaranteed outcome, or the 50:50 chance of double or nothing. In the loss-chasing task, most rats exhibited strong risk seeking preferences, gambling at the risk of incurring double the penalty, regardless of the size of the guaranteed loss. In the betting task, the majority of animals were equivocal in their choice, irrespective of bet size; however, a wager-sensitive subgroup progressively shifted away from the uncertain option as the bet size increased, which is reminiscent of risk aversion. BLA lesions increased preference for the smaller guaranteed loss in the loss-chasing task, without affecting choice on the betting task, which is indicative of reduced risk seeking for losses, but intact risk aversion for gains. These data support the hypothesis that the amygdala plays a more prominent role in choice biases related to losses. Given the importance of the amygdala in representing negative affect, the aversive emotional reaction to loss, rather than aberrant estimations of probability or loss magnitude, may underlie risk seeking for losses.     

NEUROMEDIA,EXTENDED KNOWLEDGE AND UNDERSTANDING

Imagine you had the functions of your smartphone miniaturized to a cellular level and accessible by your neural network. Reflection on this possibility suggests that we should not just concern ourselves with whether our knowledge is extending “out” to our devices; our devices are extending in, and with them, possibly the information that they bring. If so, then the question of whether knowledge is “extended” becomes wrapped up with the question of whether knowing is something we do, or something we can share with, or outsource to, instruments. And that in turn raises the two questions of this paper: First, to what extent does such technology put pressure on the idea that we might have more than one conception of knowledge (or types of knowledge)? And second, what is the value of states that fit these conceptions (or types) of knowledge?     

Aspirin Use is Associated with Lower Prostate Cancer Risk in Male Carriers of BRCA Mutations

Previous studies have shown that male BRCA mutation carriers stand at increased risk of developing prostate cancer and have concerns about developing cancer. Genetic counseling practitioners often discuss strategies for reducing the risk of cancer for patients at high risk due to their genetic background. Addressing modifiable health habits is one such strategy. Unfortunately, modifiable risk factors for prostate cancer have only been documented in the general population and have not yet been studied in the BRCA carrier subpopulation. Therefore, this study aimed to identify modifiable risk factors for prostate cancer in BRCA carriers. We examined prostate cancer risk factors in 74 men who were part of families with a BRCA mutation. This study examined nine dichotomous variables including: exercise, history of vasectomy, smoking history, alcohol use, finasteride use, statin use, aspirin use, coffee use, and vitamin use. The survey was sent to all cases of prostate cancer in the Hereditary Cancer Center Database at Creighton University with a known BRCA status. This study confirmed the protective benefits of daily aspirin use, which have been observed in previous studies of the general population, and suggests its benefit in BRCA carriers. Protective benefits from regular vigorous exercise and daily coffee use trended towards significance, but neither factor withstood the Bonferroni Correction for multiple comparisons.     

Distinguishing among disruptive behaviors to help predict high school graduation: Does gender matter?

This study examined unique predictive associations of aggressive and hyperactive–inattentive behaviors in elementary school with high school graduation. The current study also investigated whether these associations were moderated by gender. At Time 1, 745 children in the 3rd through 5th grades completed peer ratings on their classmates’ disruptive behaviors. At Time 2, school records were reviewed to determine whether students graduated within four years of entering high school. Results showed that gender and hyperactivity-inattention are uniquely associated with high school graduation, but childhood aggression is not. Results also indicated that gender moderated associations between hyperactivity–inattention and graduation. Among boys, hyperactive–inattentive behaviors were not significantly associated with graduation, above and beyond aggression. In contrast, among girls, hyperactive–inattentive behaviors in childhood were significantly associated with graduation even after controlling for aggression. These findings suggest that in middle childhood, hyperactive–inattentive behaviors may be a more meaningful predictor of high school graduation than other forms of early disruptive behavior (e.g., aggression), especially for girls. Such findings could have significant implications for prevention and intervention programs designed to target children at risk for dropping out of school.     

The Vagaries of Psychoanalytic Interpretation: An Investigation into the Causes of the Consensus Problem in Psychoanalysis

Though the psychoanalytic method of interpretation is seen by psychoanalysts as a reliable scientific tool for investigating the unconscious mind, its reputation has long been marred by what’s known as the consensus problem: where different analysts fail to reach agreement when they interpret the same phenomena. This has long been thought, by both practitioners and observers of psychoanalysis, to undermine its claim to scientific status. The causes of this problem, however, are dimly understood. In this paper I attempt to illuminate one important cause of the consensus problem by investigating the role which reliance on ‘associative evidence’ has in generating consensus failures. Various options for overcoming the difficulties with this form of clinical evidence are then examined. It is argued that these problems can be mitigated by the notion of overall associative fit, though they are exacerbated by certain loose standards used for what counts as acceptable associative evidence. The possibility of using more rigorous standards is discussed.     

The execution of planned detours by spider‐eating predators

Many spiders from the salticid subfamily Spartaeinae specialize at preying on other spiders and they adopt complex strategies when targeting these dangerous prey. We tested 15 of these spider‐eating spartaeine species for the capacity to plan detours ahead of time. Each trial began with the test subject on top of a tower from which it could view two boxes: one containing prey and the other not containing prey. The distance between the tower and the boxes was too far to reach by leaping and the tower sat on a platform surrounded by water. As the species studied are known to avoid water, the only way they could reach the prey without getting wet was by taking one of two circuitous walkways from the platform: one leading to the prey (‘correct’) and one not leading to the prey (‘incorrect’). After leaving the tower, the test subject could not see the prey and sometimes it had to walk past the incorrect walkway before reaching the correct walkway. Yet all 15 species chose the correct walkway significantly more often than the incorrect walkway. We propose that these findings exemplify genuine cognition based on representation.     

The biochemistry of memory: The 26year journey of a 'new and specific hypothesis'

This Special Issue of Neurobiology of Learning and Memory dedicated to Dr. Richard Thompson to celebrate his 80th birthday and his numerous contributions to the field of learning and memory gave us the opportunity to revisit the hypothesis we proposed more than 25years ago regarding the biochemistry of learning and memory. This review summarizes our early 1980s hypothesis and then describes how it was tested and modified over the years following its introduction. We then discuss the current status of the hypothesis and provide some examples of how it has led to unexpected insights into the memory problems that accompany a broad range of neuropsychiatric disorders.     

Developing physical activity interventions for youth with cystic fibrosis and congenital heart disease: Learning from their parents

Despite the benefits of physical activity for youth with cystic fibrosis (CF) and congenital heart disease (CHD), most are insufficiently active. More information is required on how to facilitate physical activity in these populations. Although there are no studies that provide information about participation in CF and CHD youth from the perspective of parents, the involvement of caregivers may be an important facilitator to physical activity in youth with chronic diseases.

Objective

This qualitative study explored how the parents of youth with CF and CHD experience physical activity, and parents commented on both their own and their child’s physical activity.

Methods

Twenty-nine parents from a CHD and CF clinic participated in a semi-structured interview, and a thematic analysis of the transcribed data was undertaken.

Results

Parents discussed the numerous benefits and barriers associated with physical activity for both child and self. Role modeling was a critical social process to overcoming barriers. Parents experiences were situated within the broader family context characterized by a prevailing sense of stress and complexity.

Conclusion

By illustrating how the parents of youth with CF and CHD understand the role of physical activity in their and their child’s life, this study provides valuable information regarding the development of interventions to increase physical activity among children with CF and CHD.     

Communication of Genetic Information by Other Health Professionals: The Role of the Genetic Counsellor in Specialist Clinics

Many children with chronic genetic diseases are followed by specialty clinics that provide genetic information as part of the care. Health services restrictions in the Republic of Ireland (ROI) can make the wait for an appointment with a genetic counsellor long. We examined whether genetic information was being adequately understood when presented by medical, but non-genetics staff to long term patients, using our national metabolic service as an example. The aim was to inform health professionals about the need or role of a genetic counsellor in a specialist setting. A questionnaire was used to assess knowledge among parents and patients affected by galactosaemia and Maple Syrup Urine Disease (MSUD). Twenty seven families with galactosemia and 10 with MSUD were interviewed in clinic. Comparative analysis showed significant differences in knowledge between parents of children with galactosemia and adult patients (p = 0.001) and between ethnicities (p > 0.05). While parents are well informed, the majority expressed a wish for more information about the condition and its transmission. Adult patients with galactosemia and parents from certain ethnic backgrounds could especially benefit from genetic counselling. This study highlights the need for a genetic counsellor in specialist clinics.
