Predicting Severity of Foreign Body Injuries in Children in Upper Airways: An Approach Based on Regression Trees

The entry of a small item into the upper airways is one of the leading causes of injuries in children up to 14 years old. The aim of this study is to characterize types of objects causing choking along with the features of the children involved in the accident and compare results with current standards. The European Survey on Foreign Bodies Injuries Study (ESFBI) collected data on foreign body injuries from 19 European countries. The data from ESFBI were selected according to the ICD-9-CM codes 933 (foreign body in the pharynx and larynx) and 934 (foreign body in the trachea, bronchi, and lungs). Both a classification tree and a linear discriminant analysis (LDA) have been set up to predict the probability that an injured child experiences a hospitalization. The classification tree provides flowchart-type decision rules and allows for analyzing the impact of the item features, the children characteristics, and the circumstances of the accidents on the severity of the foreign body injuries. Results showed that children younger than 3.5 who are involved in an accident have a high probability to experience a hospitalization.     

Multisystemic therapy project in Sweden: what factors affect the tendency of social workers to refer subjects to the research project?

This article examines some of the factors that may have affected the tendency for social workers to refer adolescents to a randomised controlled study of multisystemic therapy (MST). If we are to improve integration between researchers and the clinical setting in the future, it is important to consider those factors that affect implementation of research projects and evidence-based treatment methods. Evidence-based methods that lack the support of clinicians will have problems surviving in clinical practice. In the present study, we found that social workers' treatment ideology was associated with referral rate. Social workers who sympathised with the ideology on which MST is based referred patients to the project to a greater extent. Moreover, we found that the perception of a good work climate and good social support correlated positively with the referral rate from the unit. The results suggest that when implementing evidence-based methods, or research projects on treatment methods, researchers should consider whether the method is consistent with the current treatment ideology within the unit. Working conditions in the unit should also be considered.     

Family Disruption and Support in Later Life: A Comparative Study Between the United Kingdom and Italy

Global population aging has led to considerable disquiet about future support for frail older people; however, the determinants are poorly understood. Moreover, most industrialized societies have witnessed considerable changes in family behavior (e.g., rises in divorce and declining fertility). Such trends may have adversely affected the support systems of older people; nonetheless, only recently has research begun to address this issue. Employing data from the longitudinal British Household Panel Survey (1991–2003) and the 1998 Indagine Multiscopo sulle Famiglie "Famiglia, soggetti sociali e condizione dell'infanzia," we investigated the association between family disruptions due to divorce, separation, or death and three key dimensions of informal support: (i) frequency of contact with unrelated friends (among all respondents aged 65 years and over); (ii) co-residence with children (among unmarried mothers aged 65 years and over); and (iii) regular or frequent help received from children (e.g., household assistance including care) among parents aged 65 years and over. In addition, we conducted a comparative investigation of the relationship between family disruptions and the use of home care services (i.e., health visitor or district nurse; home help; meals-on-wheels) among parents aged 65 years and over. Our findings suggest that in a culture like the U.K.'s, where relations between kin are primarily influenced by individualistic values, support in later life appears to be primarily related to need, whereas in societies with a strong familistic culture (like Italy's), support is received irrespective of the older person's individual characteristics.     

Critical Discourse,Applied Inquiry and Public Health Action with Urban Middle School Students: Lessons Learned Engaging Youth in Critical Service-Learning

The Nuestro Futuro Saludable partnership designed a critical service-learning intervention focused on health equity and action. The 10-week afterschool intervention was implemented in a Boston middle school. Youths who took part in the intervention were knowledgeable about the social determinants of health in their communities, as well as to the barriers to health. Our findings indicate that engaging young people in a meaningful way will be critical if health improvement efforts are to be realized. We found that a critical service-learning framework that incorporates elements of applied inquiry and critical pedagogy was effective as a health intervention and provided opportunities for action.     

Sources of Status and Influence in All Female and Mixed Sex Groups*

Hollander's (1958) theory on conformity, status, and idiosyncrasy credits was tested using female rather than male groups. Each group contained either one male or one female confederate who broke procedual norms early, in the middle, late, or never during the 15 trials of an experimental game task. For some groups the task was described as a quasi-mathematical task; for others it was described as a common game. The quasi-mathematical definition of the task and male sex of the confederate resulted in greater conformity to the confederate's choice. Contrary to Hollander's theory, previous conformity was not related to influence. The results were interpreted in terms of traditional sex role expectations and in terms of the perceptual marker function that nonconformity plays in small groups. The marker function was related to perception in Hollander's original theoretical formulation.     

Affective Interaction as a Determinant of Musical Involvement*

Music may be understood as a structural representation, or symbolic “model,” of social interaction processes. Since music is a readily available expressive system in our society, individuals may use it as a socially meaningful symbolic medium within which they manage conflicting affective associations with interaction. Music listening then becomes one means by which individuals may maintain psychological well-being while adapting to complex social structures. Three initial points in this argument were examined, using high and low music listeners. High listeners were found to have more conflicting positive and negative affective associations with interaction than low or medium listeners, as measured by a TAT-type technique. The effect of role playing an affective interaction situation in an experimental design increased listening absorption in music for high but not for low listeners. High listeners were also more likely to describe musical effects in terms of symbolic participation in group processes.     

A comparison of self-perceived physical and psycho-social worker profiles of people with direct work injury, chronic low back pain, and cumulative trauma

This study investigated the psycho-social factors among injured workers and the influence of their psycho-social profile on the readiness of return to work. Sixty-four subjects with injuries on the upper limbs or lower limbs, low back pain, or cumulative trauma disorder were recruited. The workers' profiles (self-perceived physical health, mental health, and work readiness) together with the impact and types of work injury on the workers' perceived wellness were measured. The regression model of work readiness was constructed to develop a theoretical background for predicting work readiness based on different factors. The results showed that injured workers with chronic injury such as low back pain or cumulative trauma had poorer self-perception of physical health and psycho-social/mental health compared to those with direct trauma. The regression analysis further affirmed that self-perceived pain and physical functioning were significant factors influencing the readiness for returning to work. Workers with low back pain were found to have lower motivation for returning to work. Other factors such as the non-verbal intelligence of the injured workers, their anxiety level, and the support they received from family members were found to have some indirect impact on their ability to return to work, but this was not statistically proven.     

Female executives and the glass ceiling in Spain

This paper examines the findings of a survey of the personal, educational and professional profiles of a sample of male and female senior executives of companies operating in Spain. The women were found to be younger; they had fewer children, resorted to more domestic help, and earned less than the men, although they often had higher qualifications. Yet cultural patterns and institutional barriers still prevent them from making full use of their capabilities. In spite of recent legislative efforts to promote gender equity at work, more than nine out of ten senior executives are still men.     

Leveraging risk assessment for foodborne outbreak investigations: The Quantitative Risk Assessment-Epidemic Curve Prediction Model

Root cause analysis can be used in foodborne illness outbreak investigations to determine the underlying causes of an outbreak and to help identify actions that could be taken to prevent future outbreaks. We developed a new tool, the Quantitative Risk Assessment-Epidemic Curve Prediction Model (QRA-EC), to assist with these goals and applied it to a case study to investigate and illustrate the utility of leveraging quantitative risk assessment to provide unique insights for foodborne illness outbreak root cause analysis. We used a 2019 Salmonella outbreak linked to melons as a case study to demonstrate the utility of this model (Centers for Disease Control and Prevention [CDC], 2019). The model was used to evaluate the impact of various root cause hypotheses (representing different contamination sources and food safety system failures in the melon supply chain) on the predicted number and timeline of illnesses. The predicted number of illnesses varied by contamination source and was strongly impacted by the prevalence and level of Salmonella contamination on the surface/inside of whole melons and inside contamination niches on equipment surfaces. The timeline of illnesses was most strongly impacted by equipment sanitation efficacy for contamination niches. Evaluations of a wide range of scenarios representing various potential root causes enabled us to identify which hypotheses, were likely to result in an outbreak of similar size and illness timeline to the 2019 Salmonella melon outbreak. The QRA-EC framework can be adapted to accommodate any food–pathogen pairs to provide insights for foodborne outbreak investigations.
