Evaluation of two physical guidance procedures in the treatment of pediatric feeding disorder

Children with pediatric feeding disorder may refuse to consume an adequate variety and/or volume of food to maintain expected growth. They can consume food but may actively or passively refuse, resulting in escape or avoidance of eating. Behavioral interventions like positive reinforcement with escape extinction can increase consumption. However, sometimes these interventions are insufficient, especially in treating passive refusal. In these cases, physical guidance may be used to prompt an open mouth to deposit food. Research indicates open-mouth prompts are effective and rated as acceptable. This study replicated an existing physical guidance procedure, the finger prompt, and compared its efficacy and acceptability with that of a spoon prompt. This study extended research by defining and measuring passive refusal as a dependent variable and assessing social validity among different stakeholders and times. Both prompts were effective in treating food refusal, and caregivers rated the finger prompt as more preferred.     

Consumer complaints and recovery through guaranteeing self‐service technology

Self‐service technologies are shaping the future of consumer behaviour, yet consumers often experience service failure in this context. This conceptual paper focuses on self‐service technology failure and recovery. A consumer perspective is taken. Recovering from self‐service technology failure is fraught with difficulty, mainly because of the absence of service personnel. The aim of this paper is to present a theoretical framework and associated research propositions in respect to the positive role that service guarantees can play in the context of self‐service technology failure and recovery. It contributes to the consumer behaviour domain by unifying the theory pertaining to consumer complaint behaviour, service recovery, specifically consumers' perceptions of justice, and service guarantees, which are set in a distinctive self‐service technology context. It is advanced that service guarantees, specifically multiple attribute‐specific guarantees, are associated with consumer voice complaints following self‐service technology failure, which is contingent on the attribution of blame in the light of consumers' production role. Service guarantees are argued to be associated with consumers' perceptions of just recovery in the self‐service technology context when they promise to fix the problem, compensate only when the problem cannot be remedied, offer a choice of compensation that is contingent on failure severity, afford ease of invocation and collection, and provide a personalised response to failures. Previous classifications of SSTs are used to highlight the applicability of guarantees for different types of SSTs. Managerial implications based on the theoretical framework are presented, along with future research directions. Copyright © 2011 John Wiley & Sons, Ltd.     

Neuroendocrine influences in psychoimmunology and neoplasia: A review

Much recent work has focused on the interrelationships among environmental. psychological and physiological phenomena involved in immune-related disorders. with special emphasis being given to neoplastic processes. The present review looks first at the physiological pathways involved in the body's assorted and alternating responses to stressful environmental and psychological conditions and the immune system sequelae following each of two distinct psychophysiological coping responses—active coping and passive coping/helplessness reaction. Psychoimmunological findings about stressful life events. bereavement and mental depression as stressors the integrated with current psychoneuroimmunological postulates. A framework is outlined that may have utility for understanding the relationship among chronic psychological emotional stress in its many forms, accompanying neurohormonal changes. and increased susceptibility to immune-mediated neoplastic growth. Finally, the recently evolved concepts of hyper-adaptosis and cancrophilia are employed to further integrate theoretical pathways with clinical findings in the hopes of presenting a fertile base on which others may plan and conduct empirical research and intervention strategies.     

Two alternative models of health behaviour and recovery from activity limitations due to acute injury: A prospective study

Cognitions influence recovery from activity limitations. In this study we aimed to independently test, compare and combine the common sense self-regulation model (CS-SRM) and social cognitive theory (SCT) in predicting recovery from activity limitations due to acute injury. Measures were gathered at two time points 5–6 weeks apart. The sample consisted of 146 university students (Mean age: 21.86, SD: 4.83, 62% female) with a heterogeneous range of injuries that limited their participation in physical activity. The dependent variable was recovery from activity limitations (Physical Functioning?–?Short Form-36). The predictor variables were measured using the Brief Illness Perception Questionnaire and SCT items designed according to theoretical recommendations. Time-line (TL) and self-efficacy (SE) were significant predictors of recovery in a multivariate analysis, controlling for reported pain at Time 1. A combined model including the best predictors from both models, TL (β = ?0.25, p < 0.05, R ² change = 0.17, p < 0.01) and SE (β =0.31, p < 0.05, R ² change = 0.05, p < 0.05), accounted for a significant amount of the variance in recovery from activity limitations. A combination of key variables from both models may be particularly useful for understanding the cognitive factors that influence recovery from activity limitations.     

Tensile behaviour of submicrocrystalline ferritic steel processed by large-strain deformation

Mechanical tests have been carried out on Fe–15%Cr ferritic stainless steel with various microstructures. Ultrafine-grained microstructures with grain sizes of 0.2–0.3 µm were developed by large-strain cold-working and light annealing. The effects of severe deformation on the mechanical behaviour of as-processed and recovered steel were evaluated with reference to the same material having conventional work-hardened and recrystallised microstructures. Despite the low dislocation density in the fine grain interiors in the as-processed state, the samples with strain-induced submicrocrystalline structure were characterised by high internal stresses that resulted in a higher strength than could be expected from simple grain-size strengthening. These internal stresses were associated with a non-equilibrium state of strain-induced grain boundaries after severe deformation.     

Initial sintering of cylindrical particles of different sizes by surface diffusion

Sintering of two cylindrical particles of different sizes by surface diffusion at the early stage is theoretically analysed. Formulae for the neck growth rate are derived using a variational principle and the continuity equation of vacancies. The size difference between two particles is found to influence the growth rate of the neck only when the difference is large.     

High-speed photography of low-velocity impact cracking of solid spheres

Results from a high-speed photographic study of low-velocity impact cracking of optically transparent acrylic resin and poly(methyl methacrylate) spheres of 12.7mm diameter are described. It is shown that, in a sphere undergoing an impact, cracking occurs after the sphere has been plastically deformed. The point of initiation of cracking is shown to be located at the circle of contact between the sphere and the impacting platen. The cracking then develops throughout the sphere, with cracks attaining velocities of 600-800ms^-1. It has been suggested that crack initiation at the contact circle is caused by the tensile circumferential stress, which is generated owing to the plastic flow of the sphere.     

Recovering from negative events by boosting implicit positive affect

Upregulation of implicit positive affect (PA) can act as a mechanism to deal with negative affect. Two studies tracked temporal changes in positive and negative affect (NA) assessed by self-report and the Implicit Positive and Negative Affect Test (IPANAT; Quirin, Kazén, & Kuhl, 2009). Study 1 observed the predicted increases in implicit PA after exposure to a threat-related film clip, which correlated positively with the speed of recognising a happy face among an angry crowd. Study 2 replicated increases in implicit PA after exposition to the same film clip, and showed that such increases were enhanced by priming self-referential stimuli. The findings are discussed against the background of personality systems interaction (PSI) theory (Kuhl, 2000, 2001), which emphasises the role of the implicit self in affect regulation.     

Multidimensional Assessment of Trauma Impact,Recovery, and Resilience

Abstract

This paper describes a recent effort to introduce Japanese clinicians to the Japanese language version of the Multidimensional Trauma Recovery and Resiliency (MTRR) measures. The MTRR was translated into Japanese and introduced to a group of Japanese clinicians to gather pilot data on trauma survivors in Japan. Although the sample size limits the generalizability of the results, the findings from a preliminary analysis of 27 cases provide promising results concerning the value of a Japanese version of the MTRR-99. Future psychometric studies of the MTRR-99, parallel to American studies of the English language version of the measure, remain to be conducted. The current investigation opens the door to a series of multicultural studies on trauma impact and resiliency.     

Interpersonal Violence,Recovery, and Resilience in Incarcerated Women

Abstract

Our first study focuses on interpersonal violence and characteristics of resilience (evaluated by the Multidimensional Trauma Resilience and Recovery [MTRR] interview and rating scales) in a sample of incarcerated women. The second study applies qualitative data analysis to a case study of one participant in group therapy for incarcerated women with a history of childhood sexual abuse. Despite extensive history of both frequent and severe abuse, the women displayed a high degree of resilience across multiple domains, including, in particular, the ability to derive meaning from traumatic events and to place the memories into context, ability to form meaningful relationships with others, and ability to regulate affect. These findings were replicated in study two, which illustrates the process of recovery from a poly-traumatic history.
