Spectacle design preferences among Chinese primary and secondary students and their parents: A qualitative and quantitative study

Purpose: To identify the specific characteristics making glasses designs, particularly those compatible with adjustable glasses, more or less appealing to Chinese children and their parents. Patients and Methods: Primary and secondary school children from urban and rural China with < = -1.00 diopters of bilateral myopia and their parents ranked four conventional-style frames identified by local optical shops as popular versus four child-specific frames compatible with adjustable spectacles. Scores based on the proportion of maximum possible ranking were computed for each style. Selected children and their parents also participated in Focus Groups (FGs) discussing spectacle design preference. Recordings were transcribed and coded by two independents reviewers using NVivo software. Results: Among 136 urban primary school children (age range 9-11 years), 290 rural secondary school children (11-17 years) and 16 parents, all adjustable-style frames (scores on 0-100 scale 25.7-62.4) were ranked behind all conventional frames (63.0-87.5). For eight FGs including 12 primary children, 26 secondary children and 16 parents, average kappa values for NVivo coding were 0.81 (students) and 0.70 (parents). All groups agreed that the key changes to make adjustable designs more attractive were altering the round lenses to rectangular or oval shapes and adding curved earpieces for more stable wear. The thick frames of the adjustable designs were considered stylish, and children indicated they would wear them if the lens shape were modified. Conclusions: Current adjustable lens designs are unattractive to Chinese children and their parents, though this study identified specific modifications which would make them more appealing.

RAIN EVENTS INFLUENCE SHORT-TERM FEEDING PREFERENCES IN THE SNAIL CEPAEA NEMORALIS

Terrestrial gastropods are both herbivores and detritivores, but the ratio between these two modes of feeding can be highly variable over time. While previous studies have examined long-term seasonal patterns in the consumption of fresh material, mechanisms explaining short-term variation in dietary preferences have not been explored. We used faecal analysis to determine how short-term variation in weather affects the ratio of herbivory to detritivory in the land snail Cepaea nemoralis. Averaged across sampling dates, c. 9% of the faeces were composed of fresh plant material, with the remainder consisting of plant litter and soil. Temperature, relative humidity and soil moisture did not affect the proportional consumption of fresh material; however, snails consumed more soil with increasing temperature. If there had not been a recent precipitation event, the mean proportion of fresh material in the faeces more than doubled on average; however, this increase only occurred in areas of low herbaceous cover. Our results suggest that an increased proportion of snails consume fresh material during dry periods to compensate for water losses. Moreover, our study highlights that studies of dietary composition in the field need to account for short-term variation in feeding
preferences caused by weather.

The perceived impact of interprofessional information sharing on young people about their sexual health care

This article presents the results from an analysis of data from service providers and young adults who were formerly in state care about how information about the sexual health of young people in state care is managed. In particular, the analysis focuses on the perceived impact of information sharing between professionals on young people. Twenty-two service providers from a range of professions including social work, nursing and psychology, and 19 young people aged 18–22 years who were formerly in state care participated in the study. A qualitative approach was employed in which participants were interviewed in depth and data were analysed using modified analytical induction (Bogdan & Biklen, 2007). Findings suggest that within the care system in which service provider participants worked it was standard practice that sensitive information about a young person’s sexual health would be shared across team members, even where there appeared to be no child protection issues. However, the accounts of the young people indicated that they experienced the sharing of information in this way as an invasion of their privacy. An unintended outcome of a high level of information sharing within teams is that the privacy of the young person in care is compromised in a way that is not likely to arise in the case of young people who are not in care. This may deter young people from availing themselves of the sexual health services.

Sexual Abuse in Malawi: Patterns of Disclosure

Potential human immunodeficiency virus transmission makes prompt disclosure of child sexual abuse in Africa critical. The pattern of disclosure of 133 children presenting to the largest hospital in Malawi were analyzed. Eighty percent presented early enough for effective use of HIV postexposure prophylaxis. Seventy-five percent of children made a disclosure of child sexual abuse; 29% spontaneously and 47% after prompting. Disclosures were most commonly made to a parent, and age did not affect the pattern of disclosure. The number of children reporting child sexual abuse is increasing, possibly because of increasing awareness, availability of services, and fear of HIV. Although prompt disclosure rates were relatively high, facilitating easier disclosure of child sexual abuse by a free telephone help-line and better training of teachers may be helpful. 

Sexual abuse of children in low-income settings:time for action

In this article, child sexual abuse in low-income settings is reviewed, including the extent of the problem, the way children present, and how they should be managed. Liaising with other agencies, training in all aspects of sexual abuse and creating an environment that is conducive to good care by all groups involved is essential. Technical details of medical examination are not covered as appropriate guidelines are accessible.

Explanations for child sexual abuse given by convicted offenders in Malawi:no evidence for "HIV cleansing"

OBJECTIVE: A commonly cited, but unproven reason given for the rise in reported cases of child sexual abuse in Sub-Saharan Africa is the "HIV cleansing myth"-the belief that an HIV infected individual can be cured by having sex with a child virgin. The purpose of this study was to explore in Malawi the reasons given by convicted sex offenders for child sexual abuse and to determine if a desire to cure HIV infection motivated their offence.

METHODS: Offenders convicted of sexual crimes against victims under the age of 18 were interviewed in confidence in Malawi's two largest prisons. During the interview the circumstances of the crime were explored and the offenders were asked what had influenced them to commit it. Each participant was asked the closed question "Did you think that having sex with your victim would cure or cleanse you from HIV?"

RESULTS: 58 offenders agreed to participate. The median (range) age of offenders and victims was 30 (16-66) years and 14 (2-17) years, respectively. Twenty one respondents (36.2%) denied that an offence had occurred. Twenty seven (46.6%) admitted that they were motivated by a desire to satisfy their sexual desires. Six (10.3%) stated they committed the crime only because they were under the influence of drugs or alcohol. None of the participants said that a desire to cure or avoid HIV infection motivated the abuse.

CONCLUSION: This study suggests that offenders convicted of a sexual crime against children in Malawi were not motivated by a desire to be cured or "cleansed" from HIV infection. A need to fulfil their sexual urges or the disinhibiting effect of drugs or alcohol was offered by the majority of participants as excuses for their behaviour.

Partially Ordered Preferences in Decision Trees: Computing Strategies with Imprecision in Probabilities

Partially ordered preferences generally lead to choices that do not abide by standard expected utility guidelines; often such preferences are revealed by imprecision in probability values. We investigate five criteria for strategy selection in decision trees with imprecision in probabilities: “extensive” Γ-maximin and Γ-maximax, interval dominance, maximality and E-admissibility. We present algorithms that generate strategies for all these criteria; our main contribution is an algorithm for Eadmissibility that runs over admissible strategies rather than over sets of probability distributions.

Ethics in sexual behavior assessment and support for people with intellectual disability

Sexuality is an issue of equality, rights, and ethics, especially when it comes to the sexuality of people with intellectual and developmental disabilities. This paper offers a discussion of ethics related to the assessment and intervention supports of sexual behavior in people with intellectual and developmental disabilities. A brief history of sexuality and disability is presented. Issues of sexual abuse of people with intellectual and developmental disabilities and the laws related to sterilization, pornography, sexual rights, and consent are explored. Finally, specific ethical concerns related to intervention by behavior analysts in the realm of sexual behavior are examined.

“Desde que eles não mostrem”: perspetivas de professores/as sobre orientação sexual e identidades LGBT.

Este estudo tem como principal objetivo compreender a complexidade da expressão de preconceitos por parte de professores/as em relação a gays e lésbicas, área em que a investigação parece ser limitada. Neste sentido, procurámos avaliar esta questão com recurso a uma amostra de 204 professores/as de 13 escolas públicas do Distrito de Évora. Na realização deste trabalho, foram aplicados três instrumentos: questionário de caracterização sociodemográfica, Questionário de Discriminação Preconceito Polimorfo (Massey, 2009) e a subescala do Heterossexismo Moderno da Escala Multidimensional de Atitudes em relação a Gays e Lésbicas (Gato, Fontaine & Carneiro, 2012). Os principais resultados encontrados sugerem que o sexo, idade, posicionamentos político e religioso dos/as participantes se encontram relacionados com a expressão de preconceitos em relação a gays e lésbicas.

Ciúme nas relações amorosas de adolescentes: Questões de género e orientação sexual

Este estudo tem como objetivo compreender as diferenças relativamente ao ciúme nas relações amorosas de adolescentes, tendo em conta o género e a orientação sexual. Para tal, foi criado um questionário (Questionário de Ciúme nas Relações Amorosas Adolescentes - QCRAA) que pretende avaliar aspetos do ciúme presentes em relações amorosas adolescentes - Preocupação, Controlo do Comportamento e Comportamentos de Investigação e Agressão. O QCRAA foi aplicado a 316 jovens, tendo sido comparados os resultados em função do género, da orientação sexual, do nível de ensino e da estabilidade da relação amorosa. Os resultados sugerem que as raparigas possuem mais comportamentos de investigação e agressão, e que os níveis de preocupação nas relações amorosas dos/as jovens variam conforme a estabilidade da relação, sendo mais elevados quando a relação não é estável. Neste estudo serão analisados e discutidos os principais resultados obtidos, bem como as suas implicações para a intervenção psicológica na prevenção da violência nas relações amorosas.

Educação sexual em contexto escolar: uma intervenção contra a vulnerabilidade na vivência da sexualidade adolescente

A sexualidade estando presente desde o nascimento, na adolescência assume novo significado. Descobre-se o primeiro amor através de uma relação de intimidade e partilha de afectos, o corpo adquire um novo sentido, o grupo torna-se importante enquanto fonte de suporte, partilha de angústias e confiança, contribuindo para o desenvolvimento do adolescente. Na adolescência, perscrutam alguns factores de risco, nomeadamente a vivência da sexualidade de forma não informada e responsável, com repercussões para a saúde física e psicológica, pelo que é imperioso intervir através de programas formativos no âmbito da sexualidade que promovam vivência desta de forma responsável. São objectivos do estudo: Promover um modelo de intervenção formativa baseado no debate e reflexão crítica sobre sexualidade em contexto de sala de aula; Construir e validar instrumentos que permitam avaliar as atitudes face à sexualidade e ainda os conhecimentos dos adolescentes sobre reprodução, planeamento familiar e infecções de transmissão sexual; Testar a eficácia de um programa de intervenção formativo a nível dos conhecimentos sobre planeamento familiar, infecções de transmissão sexual, reprodução e atitudes face à sexualidade; Testar a efectividade do programa de intervenção formativo numa amostra alargada de adolescentes, analisando também o papel das variáveis sociodemográficas, sociopsicológicas e sexuais. O trabalho de campo desenvolveu-se em três estudos distintos, no primeiro e terceiro participaram 840 adolescentes e no segundo 90. No primeiro estudo construímos e validamos os instrumentos para colheita de dados, no segundo, experimental de campo, validamos o modelo da intervenção formativa no âmbito da sexualidade e no terceiro, descritivo e correlacional, testamos a efectividade de um programa de intervenção numa amostra mais alargada. O protocolo de recolha de informação incluiu quatro escalas construídas para o efeito com o intuito de avaliar as atitudes face à sexualidade, os conhecimentos sobre planeamento familiar, infecções de transmissão sexual e reprodução e ainda a escala de insatisfação com a imagem corporal em adolescentes e a escala de satisfação com o suporte social. As raparigas e residentes na zona urbana são as que têm mais conhecimentos sobre planeamento familiar e possuem atitudes face à sexualidade mais favoráveis. Os interlocutores preferenciais sobre sexualidade são os amigos, seguidos da mãe. São os adolescentes com pouca ou moderada prática religiosa que já iniciaram a actividade sexual. São as raparigas que têm maior satisfação com o suporte social nas dimensões, satisfação com as amizades, intimidade, actividades sociais e suporte social total. Os adolescentes que já iniciaram a actividade sexual, revelam maior percepção de suporte social na dimensão satisfação com a amizade. O modelo de formação construído e aplicado influenciou as atitudes face à sexualidade, conhecimentos sobre reprodução, sobre infecções de transmissão sexual e sobre planeamento familiar. Do nosso ponto de vista, pensamos ser urgente a aplicação de programas de intervenção formativos em contexto escolar, ou outro, que integrem de uma forma harmoniosa as várias facetas da sexualidade humana, promovendo a aquisição de uma postura responsável, flexível e gratificante nos adolescentes enquanto seres sexuados.
