Estimation of Tuberculosis Risk and Incidence under Upper Room Ultraviolet Germicidal Irradiation in a Waiting Room in a Hypothetical Scenario

Environmental control measures (ventilation, high-efficiency particulate air filtration, and upper room ultraviolet germicidal irradiation [UVGI]) are recommended to effectively control tuberculosis (TB) transmission from unsuspected TB patients in high-risk settings, but the effectiveness of their use is not often clear. This study presents a simulation model for a hypothetical hospital waiting room, in which the number of susceptible immunocompetent people in the waiting room follows a Poisson distribution (M = 5) in either low (annual number of TB patients = 5) or high TB risk settings (annual number of TB patients = 50), and used the model to evaluate the reduction of TB transmission risk by upper room UVGI. An exponential dose-response model was used for TB transmission and a two-zone model was used for evaluating the effect of upper room UVGI. Upper room UVGI reduced TB risk by 1.6-fold at 3 microW/cm2 UV irradiance in the upper room in the low TB risk setting and by 4.1-fold at 15 microW/cm2 UV irradiance in the upper room in the high TB risk setting. Use of upper room UVGI also reduced the mean annual new infection rate from 2.2 to 1.3 infections per year at 3 microW/cm2 and to 0.6 infections per year at 15 microW/cm2 in our hypothetical high-risk settings. The effect of upper room UVGI was sensitive to both vertical air velocity (air mixing) and UV irradiance level. Results from partitioning variability indicate that most variability of TB transmission risk came from waiting time in our hypothetical hospital.     

Methodological standards for randomised controlled trials of interventions for preventing recurrence of child physical abuse and neglect

Despite the significant financial and human resources invested in child protection services (CPS), it is unknown whether these services are effective in preventing recurrence of child physical abuse and neglect. This paper reviews available studies evaluating the effectiveness of these interventions and identifies methodological limitations and factors that may contribute to these limitations. We searched databases to identify randomised controlled trials published in peer‐reviewed journals in the past five decades that evaluated interventions to reduce recurrence of physical abuse and neglect. We outlined ten methodological standards that are important for rigorous testing of psychosocial interventions and applied them in critically appraising identified studies. Thirteen randomised controlled trials were reviewed. This review identified methodological limitations (e.g. small sample size, lack of standardisations, contamination) that made it difficult to draw reliable conclusions as to the effectiveness of interventions. Field‐specific factors that contributed to methodological limitations (e.g. heterogeneity of sample, multiple family problems, psychosocial nature of interventions) were identified and recommendations were provided for improvement. It was concluded that it is possible to implement high‐quality trials that are ethical and feasible in the child welfare field. Copyright © 2009 John Wiley & Sons, Ltd.     

Imaginary friends: migrants' emotional accounts about friends outside Australia

Migration can have emotional costs for migrants, whose face‐to‐face friendships are ruptured. This article explores the ways that migrants managed their emotions towards old friends after migration. Excerpts from semi‐structured interviews with 20 skilled migrants are analysed to show the stoic, fantasy and disengagement accounts used to deal with ruptured relationships. Each account demonstrates a different type of emotion work, which assisted migrants to cope with the loss of friends. The article discusses how the ways that migrants thought about their friends were affected by structural aspects such as geographic and temporal distance, and normative expectations such as the obligation for the migrant to return home. The article provides insight into the personal costs of migration and highlights the loss and coping that can follow, whilst demonstrating the complexity of friendship over time and geographic distance.     

Future challenges for parenting education and support

The authors of this special edition of Child Welfare have shared current shifts in perspective about parenting and parenting education that are raising some interesting challenges. We will first briefly review the shifts identified in the articles presented here. Second, we will raise questions about the implications of these shifts for the field of parenting education.     

Parenting: a relationship-oriented and competency-based process

Parents have a complex task of guiding a specific child to maturity by using the opportunities offered by the environment, while avoiding its detrimental aspects. This article develops a theory of the parenting process that describes components of the parental role; situations where development and, thus, parenting occurs; the responsibility of parents in those situations; the attributes parents use to fulfill their role; and implications for professionals.     

Angst, Depression und die Verleugnung von Abh?ngigkeit

In this text I try to describe the intra-psychic consequences caused by internalisation of external heightened demands in today??s working situation. There has been a change from modernity??s super-ego-centered subjects to the increased ego-ideal-demands in today??s postmodern society of self-control. As a consequence of the rhetorics and ideology of permanent self-improvement, of ??positive thinking?? there is a denial of any intra-psychic conflict, any dependence. This may lead to self-exploitation, exhaustion and ??burnout?? as a self-diagnosis. People apply different strategies for coping with this situation: Application of defense mechanism like projection and splitting can only bring short-term relief. Acceptance of intra-psychic conflict, ambivalence and personal weaknesses as a form of ??intra-psychic democracy?? is a way to long-term improvements and increased tolerance for problems of the self and others.     

Charles Tilly and American Pragmatism

Charles Tilly’s work on repertoires of contention and social mechanisms was pathbreaking. In this article, I argue that his understanding of both concepts overlaps with social-theoretical work informed by the philosophical tradition of classical American pragmatism. There is no evidence that Tilly was influenced by pragmatism, but I argue that the overlap is substantial enough that large portions of his oeuvre can serve as illustrations of the explanatory power of pragmatist social science—and that Tilly’s theorization of mechanisms in particular would have been even stronger had he engaged pragmatism directly.
