Under the skin: Exploring 2-month-olds' thermal reactions in different social interactions with mother and stranger

Physiological adaptations to external stressors can reveal socio-cognitive health in infancy. With the use of thermal imaging and behavioural analyses, the current study examined the arousal markers accompanying infants’ interactions with a familiar and an unfamiliar person. To address the current research question, the mother and a complete stranger interacted with 2 to 3 month-old infants (N= 10, 2 boys)in three different conditions: Neutral, Play, and Compliment. Behavioral analyses showed that overall gaze was longer to the Stranger compared to the Mother independent of condition. Physiological findings showed that skin temperature was significantly higher with the stranger independent of condition. The regions of the face that passed the significance threshold included the maxillary area, the nose, and the forehead. Both behavioral and physiological findings emphasize the ability of the infant to distinguish between a familiar and an unfamiliar person. Most importantly, however thermal imaging has proven to be a promising tool in physiologically differentiating between variable social conditions in very young infants opening up a new experimental portal for identifying healthy physiological development.     

Detection of elder abuse: Exploring the potential use of the Elder Abuse Suspicion Index© by law enforcement in the field

There are no known instruments to aid law enforcement officers in the assessment of elder abuse (EA), despite officers’ contact with older adults. This study aimed to identify: 1) officers’ perceptions and knowledge of EA, 2) barriers in detecting EA in the field, 3) characteristics officers value in a detection tool, and to explore 4) the potential for officers to use the Elder Abuse Suspicion Index (EASI)©. Data was collected from 69 Connecticut officers who confirmed that barriers to effectively detecting EA included a lack of EA detection instruments, as well as a lack of training on warning signs and risk factors. Officers indicated that the important elements of a desirable tool for helping to detect EA included ease of use, clear instructions, and information on follow-up resources. Approximately 80% of respondents could see themselves using the EASI© in the field, and a modified version has been developed for this purpose.     

Partial logistic relevance vector machines in survival analysis

The use of relevance vector machines to flexibly model hazard rate functions is explored. This technique is adapted to survival analysis problems through the partial logistic approach. The method exploits the Bayesian automatic relevance determination procedure to obtain sparse solutions and it incorporates the flexibility of kernel-based models. Example results are presented on literature data from a head-and-neck cancer survival study using Gaussian and spline kernels. Sensitivity analysis is conducted to assess the influence of hyperprior distribution parameters. The proposed method is then contrasted with other flexible hazard regression methods, in particular the HARE model proposed by Kooperberg et al. [16]. A simulation study is conducted to carry out the comparison. The model developed in this paper exhibited good performance in the prediction of hazard rate. The application of this sparse Bayesian technique to a real cancer data set demonstrated that the proposed method can potentially reveal characteristics of the hazards, associated with the dynamics of the studied diseases, which may be missed by existing modeling approaches based on different perspectives on the bias vs. variance balance.     

Winning a Race: Narratives of Healing and Psychotherapy in Children and Adolescents Who Have Been Sexually Abused

This article explores the process of recovering from sexual abuse according to children and adolescents who have been sexually abused and have successfully completed psychotherapy. In this qualitative study, interviews were conducted with 20 participants from 8 to 18 years of age and then subject to narrative analysis. Results show that participants’ narratives of recovery involve an improvement of psychological well-being. Moreover, they feel better equipped to overcome future challenges, feeling empowered and able to retake control of their lives. Factors that support and inhibit recovery are examined, as are developmental differences. Discussion underlines the valuable role of psychotherapy in helping children and adolescents in their healing process, changing the meaning of the abusive experience, and developing new capacities.
