Blame Attributions Among Child Sexual Abuse Survivors and Disclosure of the Abuse

Child sexual abuse (CSA) disclosure is critical for survivor´s psychosocial adjustment later in life. The aim of the present study was to analyze the relationship between attributions of blame for child sexual abuse by the victim and the disclosure of the abuse to parents or caregivers while controlling for characteristics of the abuse. Female college students between 17 and 24 years of age (M = 19.44, SD = 1.64) from a southern Spanish University were surveyed. Of 1547 respondents, 153 (9.90%) reported having suffered some form of CSA before the age of 15. Information about the characteristics of abuse (age of onset, type of abuse suffered, continuity of abuse, and relationship with and age of the perpetrator) and the existence of abuse disclosure by the survivor was obtained from a self-reported questionnaire developed for the present study. The Attributions of Responsibility and Blame Scale (McMillen & Zuravin, 1997) was used to assess attributions made about CSA (self-blame, perpetrator blame and family blame). The results of a logistic regression model was statistically significant, χ² (9) = 43.856, p < .001. The model explained 41% (Nagelkerke R²) of the variance of abuse disclosure and correctly classified 85.6% of cases. Survivor disclosure was 5.50 times more likely to occur when the perpetrator was not a family member (Wald = 8.14, p < .01) and 3.95 times more likely to occur when there was not physical contact with the perpetrator (Wald = 4.30, p < .05). The occurrence of disclosure was also related to increased perpetrator age (Wald = 4.83, p < .05). With regard to the attributions of blame, the occurrence of disclosure was related to lower scores on self-blame (Wald = 6.78, p < .01) and higher scores on family blame (Wald = 9.67, p < .001). However, no relationship was found between perpetrator blame and disclosure of abuse. The results confirm the idea that not only self-blame attributions, but also family blame attributions are critical to the decision of a CSA victim to disclose abuse. The possibility that children who do not disclose abuse have a greater need to deny the occurrence of abuse, or have more confusion about being abused is discussed. Attributions of blame should be taken into serious consideration when evaluating children for possible sexual abuse.Universidad de Málaga. Campus de Excelencia Internacional Andalucía Tec

A Physical Layer Model for G3-PLC Networks Simulation

This work presents a model of the G3-PLC physical (PHY) layer tailored for network simulations. It allows simulating frequency selective channels with non-stationary colored noise. Collisions with other frames are modeled taking into account the length and the power of the interfering frames. Frame errors are estimated using the effective signal-to-interference-and-noise ratio mapping (ESM) function. The proposed PHY layer has been integrated into a distributed event-based simulator developed by Microchip. The layer 2+ stack of the simulator uses the same code that actual Microchip G3-PLC devices. Validation has been accomplished by comparing its results to a test network deployed in the laboratory. The latter consists of a coordinator and one hundred meters distributed in 5 levels. Faster-than-real-time simulations and an excellent agreement between the simulated and the measured performance indicators at the application layer have been obtained.Universidad de Málaga.

Pathways from Childhood Sexual Abuse to Trait Anxiety.

Background Children exposed to sexual abuse are at risk for developing several psychological and behavioral difficulties during adulthood. Here, direct and indirect effects of family conflict, insecurity within the family system (manifested as disengagement and/or preoccupation), and negative feelings provoked by childhood sexual abuse (CSA) on trait anxiety scores were analyzed with structural equation modeling. Both Finkelhor and Browne’s traumagenic dynamics model and Davies and Cummings Emotional Security Theory were applied. Methods A total of 168 female college student survivors of CSA participated in this study. Information regarding each participant’s abuse was obtained from a self-reported questionnaires. Emotional security was assessed with the Security in the Family System scale. To assess negative feelings regarding abuse and trait anxiety, Children’s Impact of Traumatic Events Scale-Revised and State-Trait Anxiety Inventory were applied, respectively. Results Level of family conflict was found to directly relate to emotional insecurity and trait anxiety. In addition, preoccupation strategies were found to be directly related to trait anxiety. Conversely, disengagement strategies were indirectly related to anxiety through the negative feelings provoked by abuse. Experience with other types of abuse and/or neglect was also related to emotional insecurity and feelings provoked by CSA. Meanwhile, continuity of abuse only correlated with feelings provoked by abuse. Conclusions Strong relationships between family conflict, emotional insecurity, negative feelings provoked by CSA and trait anxiety were observed. These results suggest that treatment of CSA survivors should focus on improving security within the survivors’ family system and reducing negative feelings provoked by abuse

A Structural Equation Model of Depression Risk in Young Women with a History of Child Sexual Abuse

This study aimed to propose and empirically test a model of the role of beliefs and emotions, self-destructive coping, and anxious attachment in the etiology of depression among a sample of 217 female survivors of child sexual abuse (CSA). The structural equation model showed a direct path from feelings of betrayal, self-destructive coping, and major anxious attachment to depression. The model also showed an indirect path (via self-destructive coping and anxious attachment) from feelings of powerlessness—particularly self-blame/stigma—to depression. The present results confirmed the existence of an explanatory model of depression risk in young adult women

SOA4 All Integrated Ranking: a Preference-Based, Holistic Implementation

There exist many available service ranking implementations, each one providing ad hoc preference models that offer different levels of expressiveness. Consequently, applying a single implementation to a particular scenario constrains the user to define preferences based on the underlying formalisms. Furthermore, preferences from different ranking implementation’s model cannot be combined in general, due to interoperability issues. in this article we present an integrated ranking implementation that enables the combination of three different ranking implementations developed within the EU FP7 SOA4All project. Our solution has been developed using PURI, a Preference-based Universal Ranking Integration framework that is based on a common, holistic preference model that allows to exploit synergies from the integrated ranking implementations, offering a single user interface to define preferences that acts as a façade to the integrated ranking implementation

Improving Semantic Web Services Discovery Using SPARQL-Based Repository Filtering

Semantic Web Services discovery is commonly a heavyweight task, which has scalability issues when the number of services or the ontology complexity increase, because most approaches are based on Description Logics reasoning. As a higher number of services becomes available, there is a need for solutions that improve discovery performance. Our proposal tackles this scalability problem by adding a preprocessing stage based on two SPARQL queries that filter service repositories, discarding service descriptions that do not refer to any functionality or non-functional aspect requested by the user before the actual discovery takes place. This approach fairly reduces the search space for discovery mechanisms, consequently improving the overall performance of this task. Furthermore, this particular solution does not provide yet another discovery mechanism, but it is easily applicable to any of the existing ones, as our prototype evaluation shows. Moreover, proposed queries are automatically generated from service requests, transparently to the user. In order to validate our proposal, this article showcases an application to the OWL-S ontology, in addition to a comprehensive performance analysis that we carried out in order to test and compare the results obtained from proposed filters and current discovery approaches, discussing the benefits of our proposal

On User Preferences and Utility Functions in Selection: A Semantic Approach

Discovery tasks in the context of Semantic Web Services are generally performed using Description Logics. However, this formalism is not suited when non-functional, numerical parameters are involved in the discovery process. Furthermore, in selection tasks, where an optimization algorithm is needed, DLs are not capable of computing the optimum. Although there are DLs extensions that can handle numerical parameters, they bring decidability problems. Other solutions, as hybrid approaches which use DLs in functional discovery and other formalisms in non-functional selection, do not provide a semantic framework to describe user preferences based on non-functional properties. In this work, we propose to semantically describe user preferences, so they can be used to perform selection within a hybrid solution. By using semantically described utility functions in order to define user preferences, our proposal enables interoperability between service offers and demands, while providing a high level of expressiveness in these preferences and including them within SWS descriptions.Comisión Interministerial de Ciencia y Tecnología TIN2006-0047

Naturaleza de los abusos sexuales a menores y consecuencias en la salud mental de las víctimas

ResumenObjetivoDeterminar la prevalencia, la naturaleza y las consecuencias de los abusos sexuales sufridos durante la infancia o la adolescencia.Métodos2.159 estudiantes de la Universidad de Granada respondieron voluntariamente y de forma anónima a un cuestionario sobre abuso sexual. Establecido el grupo de víctimas, se formó otro de comparación con estudiantes sin antecedentes de abusos. En una segunda sesión se evaluó la salud mental de ambos grupos.Resultados269 (12,5%) estudiantes manifestaron haber sufrido abusos sexuales antes de los 18 años de edad. El 62,8% de los abusos consistió en tocamientos y la edad media de inicio fue a los 8,8 años. Los perpetradores, mayoritariamente varones y un 44% menores de edad, solían cometer los abusos en el hogar de la víctima o en el suyo, aprovechándose de las visitas o de su estrecha vinculación. Alrededor del 50% se sirvió del engaño o del juego. En cuanto a la salud mental de las víctimas, las universitarias con antecedentes de abusos sexuales tenían menor autoestima y asertividad, y puntuaciones más altas en actitud vital negativa, depresión y ansiedad, que las del grupo de comparación. Las víctimas varones, sin embargo, sólo diferían de los universitarios sin antecedentes de abusos en su mayor nivel de ansiedad.ConclusionesLos resultados demuestran la gravedad del problema de los abusos sexuales a menores y sus consecuencias, así como las circunstancias en que se producen y el perfil de los agresores y de las víctimas; unos resultados relevantes para la planificación de programas de detección y prevención de los abusos.AbstractObjectiveTo analyze the prevalence, nature and consequences of sexual abuse during childhood or adolescence.MethodsA total of 2,159 college students from the University of Granada anonymously completed a questionnaire on sexual abuse. A group of sexual abuse survivors was established and a comparison group without a history of abuse was selected. In a second session, the socio-affective adjustment of both groups was assessed.ResultsSexual abuse before the age of 18 was reported by 269 (12.5%) students. In 62.8%, the abuse consisted of the perpetrator touching the victim and/or the victim touching the perpetrator. The average age at which the sexual abuse started was 8.8 years old. The vast majority of perpetrators were males and 44% were under-age minors. The perpetrators usually committed the sexual abuse in the victim's home or in their own homes, taking advantage of visits and/or close relationships. Almost half the perpetrators made use of deception or games. Female college students with a history of sexual abuse had lower self-esteem, were less assertive, had a more negative attitude toward life, and higher depression and anxiety scores than women in the comparison group. Male survivors, however, differed from non-survivors only in having higher anxiety levels.ConclusionsOur study demonstrates the severity of the problem of sexual abuse of minors and its consequences, the circumstances in which this abuse occurs, and the profiles of perpetrators and victims. These results are relevant for the planning of abuse detection and prevention programs

QoS-Aware Semantic Service Selection: An Optimization Problem

In order to select the best suited service among a set of discovered services, with respect to QOS parameters, a user have to state his or her preferences, so services can be ranked according to these QOS parameters. Current Se- mantic Web Services ontologies do not support the defini- tion of QOS-aware user preferences, though there are some proposals that extend those ontologies to allow selection based on those preferences. However, their selection algo- rithms are very coupled with user preferences descriptions, which are defined without semantics or at a different seman- tic level than service functionality. In this work, we present a service selection framework that transforms user prefer- ences into an optimization problem where the best service is selected. This framework is based on an ontology that conceptualizes these user preferences. Thus, we use a very expressive solution decoupled with the concrete selection technique by using XSL transformations, while describing QOS-aware user preferences at the same semantic level of functional preferences.Comisión Interministerial de Ciencia y Tecnología TIN2006-00472Junta de Andalucía TIC-253
