A Qualitative Study of the Status of Children’s Play From the Viewpoints of Experts and Suggestions for Promotion Interventions

Background: The latest national census reports the population of Iranian children (1 - 8 years old) about 11 millions. On the other hand, the latest population policies approved by supreme cultural revolution council (SCRC) will make this population increase faster. Childhood development is one of the social determinants of health, of which “child’s play” is a part. Objectives: This study is an effort to identify difficulties and challenges of the plays influential on Iranian children’s health nationwide, in order to present enhancive strategies by utilizing the views of stakeholders and national studies. Patients and Methods: Analyzing children’s play stakeholders, main organizations were identified and views of 13 informed people involved in the field were investigated through deep semi-structured interview. A denaturalized approach was employed in analyzing the data. In addition to descriptions of the state, interventions development, and designing the conceptual model, national reports and studies, and other countries’ experiences were also reviewed. Results: Society’s little knowledge of “children’s plays”, absence of administrators for children’s play, shortage of public facilities for children’s play and improper geographical and demographic availability, absence of policies for Iranian “toy”, and little attention of media to the issue are the five major problems as stated by interviewees. Conclusions: The proposed interventions are presented as “promoting the educational levels of parents and selected administrators for children’s play”, “approving the play and toy policy for Iran 2025”, and “increasing public facilities for children’s play with defined distribution and availability”.

Environmental influence on commercial fishery landings of small pelagic fish in Portugal

Small pelagic fishes are particularly abundant in areas with high environmental variability (zones of coastal upwelling and areas of tidal mixing and river discharge), and because of this, their abundance suffers large inter-annual and inter-decadal fluctuations. In Portugal, the most important species in terms of landings are European sardine, Atlantic horse mackerel and Atlantic chub mackerel. Small pelagic fish landings account for 62.8 % of the total fish biomass and represent 32.7 % of the economical value of all catches. We have investigated trends in landings of these small pelagic fishes and detected the effects of environmental factors in this fishery. In order to explain the variability of landings of small pelagic fishes, we have used official landings (1965-2012) for trawling and purse seine fisheries and applied generalized linear models, using the North Atlantic Oscillation index (NAO) (annual and winter NAO index), sea surface temperature (SST), wind data (strength and North-South and East-West wind components) and rainfall, as explanatory variables. Regression analysis was used to describe the relationship between landings and SST. The models explained between 50.16 and 51.07 % of the variability of the LPUE, with the most important factors being winter NAO index, SST and wind strength. The LPUE of European sardine and Atlantic horse mackerel was negatively correlated with SST, and LPUE of Atlantic chub mackerel was positively correlated with SST. The use of landings of three important species of small pelagic fishes allowed the detection of variations in landings associated with changes in sea water temperature and NAO index.

Towards a full cosmological exploitation of cosmic voids

A stately fraction of the Universe volume is dominated by almost empty space. Alongside the luminous filamentary structures that make it up, there are vast and smooth regions that have remained outside the Cosmology spotlight during the past decades: cosmic voids. Although essentially devoid of matter, voids enclose fundamental information about the cosmological framework and have gradually become an effective and competitive cosmological probe. In this Thesis work we present fundamental results about the cosmological exploitation of voids. We focused on the number density of voids as a function of their radius, known as void size function, developing an effective pipeline for its cosmological usage. We proposed a new parametrisation of the most used theoretical void size function to model voids identified in the distribution of biased tracers (i.e. dark matter haloes, galaxies and galaxy clusters), a step of fundamental importance to extend the analysis to real data surveys. We then applied our built methodology to study voids in alternative cosmological scenarios. Firstly we exploited voids with the aim of breaking the degeneracies between cosmological scenarios characterised by modified gravity and the inclusion of massive neutrinos. Secondly we analysed voids in the perspective of the Euclid survey, focusing on the void abundance constraining power on dynamical dark energy models with massive neutrinos. Moreover we explored other void statistics like void profiles and clustering (i.e. the void-galaxy and the void-void correlation), providing cosmological forecasts for the Euclid mission. We finally focused on the probe combination, highlighting the incredible potential of the joint analysis of multiple void statistics and of the combination of the void size function with different cosmological probes. Our results show the fundamental role of the void analysis in constraining the fundamental parameters of the cosmological model and pave the way for future studies on this topic.

Sustainable exploitation of offshore renewable energy sources

Energy transition is the response of humankind to the concerning effects of fossil fuels depletion, climate change and energy insecurity, and calls for a deep penetration of renewable energy sources (RESs) in power systems and industrial processes. Despite the high potentials, low impacts and long-term availability, RESs present some limits which need to be overcome, such as the strong variability and difficult predictability, which result in scarce reliability and difficult applicability in steady-state processes. Some technological solutions relate to energy storage systems, equipment electrification and hybrid systems deployment, thus accomplishing distributed generation even in remote sites as offshore. However, all of these actions cannot disregard sustainability, which represents a founding principle for any project, bringing together economics, reliability and environmental protection. To entail sustainability in RESs-based innovative projects, previous knowledge and tools are often not tailored or miss the novel objectives. This research proposes three methodological approaches, bridging the gaps. The first contribute adapts literature-based indicators of inherent safety and energy efficiency to capture the specificities of novel process plants and hybrid systems. Minor case studies dealing with novel P2X processes exemplify the application of these novel indicators. The second method guides the conceptual design of hybrid systems for the valorisation of a RES in a site, by considering the sustainability performances of alternative design options. Its application is demonstrated through the comparison of two offshore sites where wave energy can be valorised. Finally, “OHRES”, a comprehensive tool for the sustainable optimisation of hybrid renewable energy systems is proposed. “OHRES” hinges on the exploitation of multiple RESs, by converting ex-post sustainability indicators into discrimination markers screening a large number of possible system configurations, according to the location features. Five case studies demonstrate “OHRES” versatility in the sustainable valorisation of multiple RESs.

Neo-commodification of persons: exploitation of personal data and impact on the sharing economy

The notion of commodification is a fascinating one. It entails many facets, ranging from subjective debates on desirability of commodification to in depth economic analyses of objects of value and their corresponding markets. Commodity theory is therefore not just defined by a single debate, but spans a plethora of different discussions. This thesis maps and situates those theories and debates and selects one specific strain to investigate further. This thesis argues that commodity theory in its optima forma deals with the investigation into what sets commodities apart from non-commodities. It proceeds to examine the many given answers to this question by scholars ranging from the mid 1800’s to the late 2000’s. Ultimately, commodification is defined as a process in which an object becomes an element of the total wealth of societies in which the capitalist mode of production prevails. In doing so, objects must meet observables, or indicia, of commodification provided by commodity theories. Problems arise when objects are clearly part of the total wealth in societies without meeting established commodity indicia. In such cases, objects are part of the total wealth of a society without counting as a commodity. This thesis examines this phenomenon in relation to the novel commodities of audiences and data. It explains how these non-commodities (according to classical theories) are still essential elements of industry. The thesis then takes a deep dive into commodity theory using the theory on the construction of social reality by John Searle.

Privacidad e intimidad en las interacciones virtuales

El presente trabajo es una revisión de la literatura de investigación en Ciberpsicología centrada en las categorías de privacidad, intimidad, identidad y vulnerabilidad, y en la forma como estas se desarrollan en las redes sociales virtuales. Los principales hallazgos indicaron que son los jóvenes quienes dedican gran parte de su tiempo a interactuar en dichas redes, y a su vez, dado el manejo que les dan, tienen mayor exposición ante los posibles riesgos de estas, como el matoneo, las conductas auto lesivas, la explotación sexual y los trastornos de la alimentación. Se describen estos riesgos y se proponen posibles soluciones.

Health Care Providers' Training Needs Related to Human Trafficking: Maximizing the Opportunity to Effectively Screen and Intervene

Human trafficking is a complex and multifaceted problem that takes the form of economic, physical and sexual exploitation of people, both adults and children, who are reduced to simple products for commerce. Human trafficking in the United States also has both a domestic and an international aspect. Health care providers are in a unique position to screen for victims of trafficking and may provide important medical and psychological care for victims while in captivity and thereafter. Trafficked persons are likely to suffer a wide spectrum of health risks that reflect the unique circumstances and experiences in a trafficked victim’s life. Although trafficked victims typically have experienced inadequate medical care, once contact is made by the victim with the health care professionals, the opportunity then exists to identify, treat, and assist such victims. The range of services and supports required to appropriately respond to human trafficking victims once identified is broad and typically goes beyond just what is immediately provided by the health care professional and includes safe housing, legal advice, income support, and, for international victims, immigration status related issues. An informed and responsive community is necessary to serve both the international and domestic victims of human trafficking, and needs assessments demonstrated a number of barriers that hindered the delivery of effective services to human trafficking victims. One of the consistent needs identified to combat these barriers was enhanced training among all professionals who might come in contact with human trafficking victims. We highlight the efforts of the Houston Rescue and Restore Coalition (HRRC), a local grassroots non-profit organization whose mission focuses on raising awareness of human trafficking in the Greater Houston Metropolitan area. HRRC responded to the consistent recommendation from various community needs assessments for additional training of front line professionals who would have the opportunity to identify human trafficking victims and supported the design and pilot testing of a health professions training program around human trafficking. Dissemination of this type of training along with careful evaluation and continued refinement will be one way for health care professionals to engage in a positive manner with human trafficking victims.

Expertise and decision making among clinicians in investigations of alleged child sexual abuse

The purpose of the present thesis was to explore different aspects of decision making and expertise in investigations of child sexual abuse (CSA) and subsequently shed some light on the reasons for shortcomings in the investigation processes. Clinicians’ subjective attitudes as well as scientifically based knowledge concerning CSA, CSA investigation and interviewing were explored. Furthermore the clinicians’ own view on their expertise and what enhances this expertise was investigated. Also, the effects of scientific knowledge, experience and attitudes on the decision making in a case of CSA were explored. Finally, the effects of different kinds of feedback as well as experience on the ability to evaluate CSA in the light of children’s behavior and base rates were investigated. Both explorative and experimental methods were used. The purpose of Study I was to investigate whether clinicians investigating child sexual abuse (CSA) rely more on scientific knowledge or on clinical experience when evaluating their own expertise. Another goal was to check what kind of beliefs the clinicians held. The connections between these different factors were investigated. A questionnaire covering items concerning demographic data, experience, knowledge about CSA, selfevaluated expertise and beliefs about CSA was given to social workers, child psychiatrists and psychologists working with children. The results showed that the clinicians relied more on their clinical experience than on scientific knowledge when evaluating their expertise as investigators of CSA. Furthermore, social workers possessed stronger attitudes in favor of children than the other groups, while child psychiatrists had more negative attitudes towards the criminal justice system. Male participants held less strong beliefs than female participants. The findings indicate that the education of CSA investigators should focus more on theoretical knowledge and decision making processes as well as the role of beliefs In Study II school and family counseling psychologists completed a Child Sexual Abuse Attitude and Belief Scale. Four CSA related attitude and belief subscales were identified: 1. The Disclosure subscale reflecting favoring a disclosure at any cost, 2. The Pro-Child subscale reflecting unconditional belief in children's reports, 3. The Intuition subscale reflecting favoring an intuitive approach to CSA investigations, and 4. The Anti Criminal Justice System subscale reflecting negative attitudes towards the legal system. Beliefs that were erroneous according to empirical research were analyzed separately. The results suggest that some psychologists hold extreme attitudes and many erroneous beliefs related to CSA. Some misconceptions are common. Female participants tended to hold stronger attitudes than male participants. The more training in interviewing children the participants have, the more erroneous beliefs and stronger attitudes they hold. Experience did not affect attitudes and beliefs. In Study III mental health professionals’ sensitivity to suggestive interviewing in CSA cases was explored. Furthermore, the effects of attitudes and beliefs related to CSA and experience with CSA investigations on the sensitivity to suggestive influences in the interview were investigated. Also, the effect of base rate estimates of CSA on decisions was examined. A questionnaire covering items concerning demographic data, different aspects of clinical experience, self-evaluated expertise, beliefs and knowledge about CSA and a set of ambiguous material based on real trial documents concerning an alleged CSA case was given to child mental health professionals. The experiment was based on a 2 x 2 x 2 x 2 (leading questions: yes vs no) x (stereotype induction: yes vs no) x (emotional tone: pressure to respond vs no pressure to respond) x (threats and rewards: yes vs no) between-subjects factorial design, in which the suggestiveness of the methods with which the responses of the child were obtained were varied. There was an additional condition in which the material did not contain any interview transcripts. The results showed that clinicians are sensitive only to the presence of leading questions but not to the presence of other suggestive techniques. Furthermore, the clinicians were not sensitive to the possibility that suggestive techniques could have been used when no interview transcripts had been included in the trial material. Experience had an effect on the sensitivity of the clinicians only regarding leading questions. Strong beliefs related to CSA lessened the sensitivity to leading questions. Those showing strong beliefs on the belief scales used in this study were even more prone to prosecute than other participants when other suggestive influences than leading questions were present. Controversy exists regarding effects of experience and feedback on clinical decision making. In Study IV the impact of the number of handled cases and of feedback on the decisions in cases of alleged CSA was investigated. One-hundred vignettes describing cases of suspected CSA were given to students with no experience with investigating CSA. The vignettes were based on statistical data about symptoms and prevalence of CSA. According to the theoretical likelihood of CSA the children described were categorized as abused or not abused. The participants were asked to decide whether abuse had occurred. They were divided into 4 groups: one received feedback on whether their decision was right or wrong, one received information about cognitive processes involved in decision making, one received both, and one did not receive feedback at all. The results showed that participants who received feedback on their performance made more correct positive decisions and participants who got information about decision making processes made more correct negative decisions. Feedback and information combined decreased the number of correct positive decisions but increased the number of correct negative decisions. The number of read cases had in itself a positive effect on correct positive decision.

Exploitation sexuelle à des fins commerciales en Inde : expériences de femmes prostituées à la gare de Varanasi

L’exploitation sexuelle à des fins commerciales fait de plus en plus de victimes en Inde. Compte tenu de l’ampleur constatée du phénomène et de la gravité de ses multiples conséquences, notre recherche vise à mieux connaître et comprendre l’expérience vécue par les femmes se livrant à des activités sexuelles contre rémunération. Plus précisément, elle a comme objectifs de décrire le cheminement ayant conduit ces femmes à se livrer à de telles pratiques ainsi que leur réalité quotidienne et comment elles perçoivent leur situation pour ensuite être en mesure de formuler des propositions d’interventions préventives ou s’adressant aux femmes se livrant déjà à des activités sexuelles à des fins commerciales. Nous avons choisi de nous intéresser aux femmes vivant et se prostituant à la gare de Varanasi. Une approche qualitative a été privilégiée dans la réalisation de la recherche. Huit entrevues ont été réalisées avec des femmes et fillettes qui se prostituent à la gare, trois avec des intervenants sociaux y travaillant et l’observation in situ a permis d’enrichir le matériel recueilli. Ces prostituées sont souvent issues d’un milieu familial dysfonctionnel. C’est en situation de fuite ou d’abandon familial qu’elles s’installent à la gare. Il s’agit d’un endroit où les femmes sont en situation d’extrême vulnérabilité et où les conditions de vie sont misérables. Exposées aux dangers de la vie à la gare et accessibles aux proxénètes, la prostitution devient une option pour y survivre. Les besoins d’intervention auprès de ces femmes sont multiples et y répondre est complexe. Une approche favorisant la réduction des méfaits et la prévention paraît être les avenues à privilégier.

Disclosure of Child Sexual Abuse : Impact of Interviewers’ Attitudes & Children's Collaboration during Forensic Interviews

L’agression sexuelle (AS) commise envers les enfants est un sujet complexe à enquêter et les allégations reposent souvent exclusivement sur le témoignage de l’enfant. Cependant, même quand l’enfant divulgue une AS, il peut être réticent à révéler certains détails personnels et gênants de l’AS à un étranger. Étant donné qu’il n'est pas toujours possible d'obtenir le consentement de filmer et qu’il est relativement difficile de mesurer l’attitude non verbale de l’enfant et celui de l’enquêteur au cours des entrevues d’investigations, cette recherche a été novatrice dans sa création d’échelles verbales de telles attitudes. Afin de déterminer la corrélation de l’attitude des enquêteurs et la collaboration des enfants, 90 entrevues d’enfants âgés de 4 à 13 ans ont été analysées. Les entrevues ont été enregistrées sur bande audio, transcrites et codifiées à l'aide des sous-échelles verbales d'attitudes soutenantes et non-soutenantes des enquêteurs ainsi que d’attitudes de résistance et de coopération de la part de l'enfant. La proportion des détails sur l’AS fournie par les enfants a également été calculée. Afin de comparer les entrevues avec et sans le protocole du National Institute of Child Health and Human Development (NICHD), une MANCOVA, contrôlant pour l’âge de l’enfant et la proportion de questions ouvertes, démontre tel qu’attendu que les entrevues avec le protocole obtiennent plus de détails fournis à la suite des questions ouvertes que les entrevues sans le protocole. Cependant, aucune différence ne ressort quant aux attitudes de l’enfant et celle de l’enquêteur. Afin de trouver le meilleur prédicteur de la quantité de détails dévoilés par les enfants, une analyse de régression multiple hiérarchique a été faite. Après avoir contrôlé pour l'âge de l’enfant, l’utilisation du protocole et la proportion de questions ouvertes, la résistance de l’enfant et l’attitude non-soutenante de l’enquêteur expliquent 28 % supplémentaire de la variance, tandis que la variance totale expliquée par le modèle est de 58%. De plus, afin de déterminer si la collaboration de l’enfant et l’attitude de l’enquêteur varient en fonction de l’âge des enfants, une MANOVA démontre que les enquêteurs se comportent similairement, quel que soit l'âge des enfants. Ceci, malgré le fait que les jeunes enfants sont généralement plus réticents et coopèrent significativement moins bien que les préadolescents. Finalement, une régression multiple hiérarchique démontre que le soutien de l'enquêteur est le meilleur prédicteur de la collaboration des enfants, au-delà des caractéristiques de l'enfant et de l’AS. Bien que l’utilisation du protocole NICHD ait permis des progrès considérables dans la manière d’interroger les enfants, augmentant la proportion de détails obtenus par des questions ouvertes/rappel libre et amplifiant la crédibilité du témoignage, l’adhésion au protocole n’est pas en soi suffisante pour convaincre des jeunes enfants de parler en détail d’une AS à un inconnu. Les résultats de cette thèse ont une valeur scientifique et contribuent à enrichir les connaissances théoriques sur les attitudes de l'enfant et de l'enquêteur exprimées lors des entrevues. Même si les enquêteurs de cette étude offrent plus de soutien aux enfants résistants, indépendamment de leur âge, pour promouvoir la divulgation détaillée de l’AS, de meilleures façons de contrer les attitudes de résistance exprimées par les jeunes enfants et une minimisation des attitudes non-soutenantes lors des entrevues sont nécessaires.

Graceful remedies: understanding grace in the Catholic Church's treatment of clerical child sexual abuse

This article examines advocacy of Catholic restorative justice for clerical child sexual abuse from the standpoint of feminist criminological critiques of the use of restorative mediation in sexual offence cases. In particular, it questions the Catholic invocation of grace and forgiveness of survivors of abuse in light of critical feminist concerns about the exploitation of emotions in restorative practices, especially in regard to sexual and other gender-based offences. In the context of sexual abuse, the Catholic appeal to grace has the potential for turning into an extraordinary demand made of victims not only to rehabilitate offenders and the church in the eyes of the community, but also to work towards the spiritual absolution of the abuser. This unique feature of Catholic-oriented restorative justice raises important concerns in terms of feminist critiques of the risk of abuses of power within mediation, and is also incompatible with orthodox restorative justice theory, which, although it advocates a ‘spiritual’ response to crime, is concerned foremost with the rights, needs and experiences of victims.

Children’s literature: sexual identity, gender and childhood

On the twenty-third of May 2015, Ireland became the first country to legalise same-sex marriage by popular vote. This event reversed a large part, if not all, of Ireland’s reputation for a Catholic-led conservatism concerning sexual and gender identities. I argue in this article that we can see a parallel-in-miniature to this momentous shift in something of a reversal of children’s literature’s views in this respect too, and I will concentrate on exploring what is at stake in the ways that childhood, sexual and gender identities are constructed in some recent children’s literature criticism in the light of these shifts. My interest is to consider: what is the ever-burgeoning interest in the gay, queer, cross-dressing, transsexual or transgender child precisely about? I ask this question on the grounds of not assuming that this interest in these identities arises necessarily simply out of a self-evident, progressive, liberatory impulse, and, alongside this, I also do not assume that ‘identities’ are essential, self-organised traits awaiting revelation and liberation.

Social determinants of sexual satisfaction in Spain considered from the gender perspective

Aims: To describe gender- and social class-related inequalities in sexual satisfaction and analyze their relationship with self-perceived health status. Methods: This population-based, cross-sectional study included 7384 sexually active people aged 16 years and over residing in Spain in 2009 (3951 men and 3433 women). The explanatory variables were gender, age, social class, share in performing domestic tasks, spend time looking after oneself, collaborate economically in supporting the family, caring for children, self-perceived health status, and the desire to increase or decrease frequency of having sexual relations. Bivariate and multivariate logistic regression models were fitted. Results: Among women, sexual satisfaction declines progressively after age 45. Sexual satisfaction is 1.7 times higher among women who look after themselves and who feel good compared with those who do not. The odds of wanting to increase sex is 3.3 times higher for women who are satisfied compared with women who desire a lower frequency of sexual intercourses; and good perceived health was associated with sexual satisfaction. In satisfied men, the corresponding odds is 1.9 times that of men desiring to reduce their frequency of sex. Conclusions: Gender and social class inequalities are found in sexual satisfaction. This is associated with perceived health status, adding evidence in support of the World Health Organization definition of sexual health.

The influence of simulated exploitation onPatella vulgatapopulations: protandric sex change is size-dependent

Grazing mollusks are used as a food resource worldwide, and limpets are harvested commercially for both local consumption and export in several countries. This study describes a field experiment to assess the effects of simulated human exploitation of limpets Patella vulgata on their population ecology in terms of protandry (age-related sex change from male to female), growth, recruitment, migration, and density regulation. Limpet populations at two locations in southwest England were artificially exploited by systematic removal of the largest individuals for 18 months in plots assigned to three treatments at each site: no (control), low, and high exploitation. The shell size at sex change (L50: the size at which there is a 50:50 sex ratio) decreased in response to the exploitation treatments, as did the mean shell size of sexual stages. Size-dependent sex change was indicated by L50 occurring at smaller sizes in treatments than controls, suggesting an earlier switch to females. Mean shell size of P. vulgata neuters changed little under different levels of exploitation, while males and females both decreased markedly in size with exploitation. No differences were detected in the relative abundances of sexual stages, indicating some compensation for the removal of the bigger individuals via recruitment and sex change as no migratory patterns were detected between treatments. At the end of the experiment, 0–15 mm recruits were more abundant at one of the locations but no differences were detected between treatments. We conclude that sex change in P. vulgata can be induced at smaller sizes by reductions in density of the largest individuals reducing interage class competition. Knowledge of sex-change adaptation in exploited limpet populations should underpin strategies to counteract population decline and improve rocky shore conservation and resource management.
