Sex Talk: A Multiple Case Study to Explore and Understand Parent-Child Sexual Health Communication in Chinese Immigrant Families

Parent-child sexual health communication can be beneficial. Many factors affect such communication in Chinese immigrant families. This qualitative study explored the influences of acculturation, parenting, and parental participation in the Raising Sexually Healthy Children Program (RSHC) on such communication. With a hermeneutic framework, the purpose was to develop understanding based on the topic, context, and researcher interpretations. Twelve interviews elicited data from six parent-child dyads, three from the RSHC. Analysis involved coding processes; data were compared repeatedly and organized into themes. Perceived personality differences between generations were confounded with cultural communicative differences. Parents used implicitness observed in Chinese culture to establish "open" communication; children expected explicitness observed in Western culture. Post- RSHC, parents perceived themselves as more open to talking about sex; children did not perceive such parental changes. Future research should include joint interviews and longitudinal program evaluation. Future practice should focus on cross-cultural communication and involving children in RSHC.

“I thought I’d be safe there”:pre-empting blame in the talk of women reporting rape

One routine “common sense” means of explaining sexual violence is the ideologically facilitated tendency to blame the victim, and previous research has identified patterns of victim-blaming in the talk of perpetrators of rape, and also in that of the professionals who deal with rape in their day-to-day work. This article focuses on the discursive resources drawn on in police interviews by rape victims themselves as they attempt to account for their own behaviour in relation to the attack. It identifies and describes points within interviewees’ talk where they produce “accounts” (Potter and Wetherell, 1987), and considers what these tell us about the participants’ shared understanding of what is relevant to the on-going talk. Occasions when there is evidence of a mis-match in the understanding of the participants will also be discussed. The analyses illustrate that for the accounts of interviewees to be heard as relevant, a number of prevalent and problematic themes of victim-blaming must be assumed. Interviewees anticipate and pre-empt implications that various aspects of their own behaviour contributed to their attack, and interviewers vary in the level of skill they display at negotiating these shared understandings.

No right to sext? A critical examination of media and legal debates about teenage girls' sexual agency in the digital age

Advances in digital photography and distribution technologies enable many people to produce and distribute images of their sex acts. When teenagers do this, the photos and videos they create can be legally classified as child pornography since the law makes no exception for youth who create sexually explicit images of themselves. The dominant discussions about teenage girls producing sexually explicit media (including sexting) are profoundly unproductive: (1) they blame teenage girls for creating private images that another person later maliciously distributed and (2) they fail to respect—or even discuss—teenagers’ rights to freedom of expression. Cell phones and the internet make producing and distributing images extremely easy, which provide widely accessible venues for both consensual sexual expression between partners and for sexual harassment. Dominant understandings view sexting as a troubling teenage trend created through the combination of camera phones and adolescent hormones and impulsivity, but this view often conflates consensual sexting between partners with the malicious distribution of a person’s private image as essentially equivalent behaviors. In this project, I ask: What is the role of assumptions about teen girls’ sexual agency in these problematic understandings of sexting that blame victims and deny teenagers’ rights? In contrast to the popular media panic about online predators and the familiar accusation that youth are wasting their leisure time by using digital media, some people champion the internet as a democratic space that offers young people the opportunity to explore identities and develop social and communication skills. Yet, when teen girls’ sexuality enters this conversation, all this debate and discussion narrows to a problematic consensus. The optimists about adolescents and technology fall silent, and the argument that media production is inherently empowering for girls does not seem to apply to a girl who produces a sexually explicit image of herself. Instead, feminist, popular, and legal commentaries assert that she is necessarily a victim: of a “sexualized” mass media, pressure from her male peers, digital technology, her brain structures or hormones, or her own low self-esteem and misplaced desire for attention. Why and how are teenage girls’ sexual choices produced as evidence of their failure or success in achieving Western liberal ideals of self-esteem, resistance, and agency? Since mass media and policy reactions to sexting have so far been overwhelmingly sexist and counter-productive, it is crucial to interrogate the concepts and assumptions that characterize mainstream understandings of sexting. I argue that the common sense that is co-produced by law and mass media underlies the problematic legal and policy responses to sexting. Analyzing a range of nonfiction texts including newspaper articles, talk shows, press releases, public service announcements, websites, legislative debates, and legal documents, I investigate gendered, racialized, age-based, and technologically determinist common sense assumptions about teenage girls’ sexual agency. I examine the consensus and continuities that exist between news, nonfiction mass media, policy, institutions, and law, and describe the limits of their debates. I find that this early 21st century post-feminist girl-power moment not only demands that girls live up to gendered sexual ideals but also insists that actively choosing to follow these norms is the only way to exercise sexual agency. This is the first study to date examining the relationship of conventional wisdom about digital media and teenage girls’ sexuality to both policy and mass media.

Cross talk Initiated by Endothelial Cells Enhances Migration and Inhibits Anoikis of Squamous Cell Carcinoma Cells through STAT3/Akt/ERK Signaling

It is well known that cancer cells secrete angiogenic factors to recruit and sustain tumor vascular networks. However, little is known about the effect of endothelial cell-secreted factors on the phenotype and behavior of tumor cells. The hypothesis underlying this study is that endothelial cells initiate signaling pathways that enhance tumor cell survival and migration. Here, we observed that soluble mediators from primary human dermal microvascular endothelial cells induce phosphorylation of signal transducer and activator of transcription 3 (STAT3), Akt, and extracellular signal-regulated kinase (ERK) in a panel of head and neck squamous cell carcinoma (HNSCC) cells (OSCC-3, UM-SCC-1, UM-SCC-17B, UM-SCC-74A). Gene expression analysis demonstrated that interleukin-6 (IL-6), interleukin-8 (CXCL8), and epidermal growth factor (EGF) are upregulated in endothelial cells cocultured with HNSCC. Blockade of endothelial cell-derived IL-6, CXCL8, or EGF by gene silencing or neutralizing antibodies inhibited phosphorylation of STAT3, Akt, and ERK in tumor cells, respectively. Notably, activation of STAT3, Akt, and ERK by endothelial cells enhanced migration and inhibited anoikis of tumor cells. We have previously demonstrated that Bcl-2 is upregulated in tumor microvessels in patients with HNSCC. Here, we observed that Bcl-2 signaling induces expression of IL-6, CXCL8, and EGF, providing a mechanism for the upregulation of these cytokines in tumor-associated endothelial cells. This study expands the contribution of endothelial cells to the pathobiology of tumor cells. It unveils a new mechanism in which endothelial cells function as initiators of molecular crosstalks that enhance survival and migration of tumor cells.

Formal caregivers of older adults: reflection about their practice

OBJECTIVE To understand the job function of caregivers of older adults and contribute to the debate on the consolidation of this professional practice. METHODOLOGICAL PROCEDURES This is a descriptive, qualitative, and exploratory study. Four focal group sessions were performed in 2011 with 11 elderly companions, formal caregivers of older adults in the Programa Acompanhante de Idosos (Program for Caregivers of Older Adults), Sao Paulo, SP, Southeastern Brazil. These sessions, guided by a semi-structured script, were audio-recorded and fully transcribed. Data were analyzed using the Content Analysis technique, Thematic Modality. RESULTS In view of considering the caregivers of older adults as a new category of workers, it was difficult to define their duties. The elderly companions themselves as well as the care receivers, their families, and the professionals that comprised the team were unclear about their duties. The professional practice of these formal caregivers has been built on the basis of constant discussions and negotiations among them and other team members in Programa Acompanhante de Idosos during daily work. This was achieved via a recognition process of their job functions and by setting apart other workers’ exclusive responsibilities. CONCLUSIONS The delimitation of specific job functions for elderly companions is currently one of the greatest challenges faced by these workers to develop and consolidate their professional role as well as improve Programa Acompanhante de Idosos.

Envelhecimento ativo, capacidade funcional e atividade física: análise de fatores que contextualizam o processo de envelhecimento e sua percepção por parte de pessoas idosas

RESUMO: O envelhecimento populacional saudável ocupa parte da agenda do processo do envelhecimento humano, retratando uma preocupação social com repercussões nas economias societárias. O processo de envelhecimento, quando abordado fora do paradigma do envelhecimento saudável, desconsidera socialmente o potencial humano das pessoas idosas, promovendo a segregação e motivando atitudes de preconceito e discriminação, além de desperdiçar a experiência, o saber, a cultura e a capacidade de participação da pessoa idosa como contributo para a sociedade a que ela está inserida. O foco central da Política Nacional de Saúde do Idoso brasileira se inscreve na promoção de um envelhecimento saudável, nomeadamente por meio da manutenção da capacidade funcional ao valorizar a autonomia, a independência física e a integridade mental da pessoa idosa. O desafio para a viabilização do processo de envelhecimento ativo e bem-sucedido consiste na maximização das capacidades, potencialidades e recursos pessoais, comunitários e políticos. Pressupõe, também, uma concepção ampliada de viver, contextualizada no contínuo da vida, capaz de externar a preocupação com a saúde e o bem-estar, integrando as pessoas em fase de envelhecimento no contexto do ciclo de vida. Diante do exposto, a presente investigação objetivou conhecer os determinantes de envelhecimento ativo e bem-sucedido, numa população em processo de envelhecimento e relacioná-los com as ―práticas/conteúdos‖ e representações / significados‖ sobre o envelhecimento, as atividades físicas e a capacidade funcional. A investigação foi estruturada em três estudos: no primeiro foi criado e testado o instrumento ―Envelhecimento ativo, capacidade funcional e atividade física‖, na cidade de Lisboa, Portugal, e posteriormente realizada sua adaptação cultural e linguística do português de Portugal para o do Brasil. No segundo foi feita uma pesquisa observacional do tipo survey, descritiva e exploratória com o objetivo de conhecer as relações esteabelecidas entre o envelhecimento bem-sucedido, ativo, a atividade física e a capacidade funcional de uma população em processo de envelhecimento; e no terceiro momento foi realizado um estudo de cariz qualitativo com o objetivo de captar as percepções e comportamentos dos entrevistados diante do fato de se sentirem ou não pessoas idosas ou envelhecidas. Foram adotados os seguintes referenciais teóricos: envelhecimento ativo, envelhecimento bem sucedido, concepção muldidimensional do processual do envelhecimento (determinantes pessoais, familiares, sociais, psicocomunicacionais, econômicos e de saúde), atividade física e capacidade funcional e abordados à luz do perfil demográfico e da experiência das realidades européias, americana e brasileira. Foram triagulados métodos e técnicas (entrevista individual gravada, mensurações e questionário). Participaram pessoas com 60 anos de idade ou mais vinculadas que frequentam dois programas públicos destinados às pessoas idosas na cidade de Juiz de Fora, Minas Gerais, Brasil e foram excluidas as participações de pessoas com dependência para atividades da vida diária, para as atividades instrumentais da vida diária e com alteração do nível de consciência. Amostra aleatória estratificada composta por 326 participantes na qual foram realizadas mensurações e amostra por tipicidade construída a partir da base amostral composta de 87 participantes na qual foi realizada entrevista individual gravada. Atendidos todos os requisitos éticos e legais de pesquisa envolvendo seres humanos, segundo legislação brasileira. Aplicada Análise Fatorial e selecionados 11 fatores com 31 variáveis que contemplaram os determinantes do processo de envelhecimento ativo. Realizado reajustamento da análise fatorial,por questão de coerência conceptual, sendo selecionado oito fatores nomeados de acordo com o referencial teórico adotado que resultou em 25 variáveis que abordaram a participação em atividades e acesso aos serviços de saúde; à atividade física; à convivência, interação e avaliação do contato social; à escolaridade e renda; à saúde percebida e ao voluntariado. Utilizado como marcador para a atividade aeróbia o perfil da sobrecarga da atividade física semanal em consonância com diretrizes e recomendações de atividades aeróbias de intensidade moderada para as pessoas idosas. Identificado que 60,7% dos entrevistados realizam atividade física insuficiente. Os indicadores antropométricos utilizados evidenciaram índices de sobrepeso e de obesidade tanto entre os homens quanto entre as mulheres. Houve correlação do índice de massa corporal (IMC) com as medidas efetuadas segundo as faixas etárias. A análise inferencial possibilitou relacionar os determinantes do envelhecimento ativo, as medidas antropométricas e as variáveis sociodemográficas (escolaridade e idade), sendo obtidos os seguintes destaques: 1) à medida em que a idade aumenta, diminuem os níveis de prática da atividade física, dos contatos com as pessoas para conversar (das relações de convivência), dos trabalhos de voluntariado e das relações familiares e intergeracionais; 2) foi identificado um alinhamento conceptual dos diferentes determinantes concorrentes para um envelhecimento ativo à luz da prática da atividade física com a convivência e interação com os familiares e com auto-avaliação positiva da saúde percebida e atividade física; 3) quanto maior a idade menor os anos de escolaridade; 4) a diminuição da área transversa do braço e do IMC à medida que a idade aumenta, retratou diminuição da adiposidade corporal que está associada à perda da massa magra. A categorização do discurso dos 87 entrevistados permitiu captar a percepção do processo de envelhecimento por dois critérios antagônicos: preservação da autonomia e presença da deterioração. Foi caracterizado o sistema de crenças dos participantes com 1090 emissões de crenças. Houve tendência do sistema de crenças à centralidade com 638 (58,6%) crenças retratando concepções e situações difíceis de serem modificadas por processos educacionais. Os resultados obtidos diagnosticaram e reiteraram a tendência de incremento numérico de pessoas com 60 anos de idade ou mais na cidade brasileira de Juiz de Fora. Embora o estatuto do idoso esteja alicerçado em princípios do envelhecimento saudável e ativo ficou evidenciado a necessidade de estratégias para implementá-la com vistas a impactos sociais, econômicas e de saúde na perspectiva da prática de atividade física e da preservação da capacidade funcional. Constituem contribuição da presente investigação: 1) fundamentos teóricos e informação sobre juiz-foranos com 60 anos de idade ou mais segundo dimensões social, econômica, cultural e espiritual numa concepção ampliada de saúde; 2) abordagem do envelhecimento de forma processual e integrada, multidimensional e articulada com o ciclo da vida; 3) diagnóstico do grau de autonomia dos participantes permitindo subsidiar decisões para melhorar a capacidade funcional dos mesmos; 4) processo investigativo utilizando modelos teóricos que permitiram estabelecer um diagnóstico local e contextualizar o processo de envelhecimento para os participantes e 5) sobrecarga semanal de atividade física e os indicadores antropométricos dos participantes a ponto de subsidiar parâmetros de indicação terapêutica para manutenção da capacidade funcional.-------- ABSTRACT: The populational healthy aging holds part of the process of the human aging agenda, portraying a social concern with the repercussion in societary economies. The aging process when addressed out of the healthy aging paradigm socially disregard the human potential of the elderly, promoting segregation and motivating acts of prejudice and discrimination, in addition to the waste of experience, knowledge, culture and the participatory capacity of an older person in contributting to the society they are a part of. The Brazilian National Health Policy for the Elderly has its main focus in promoting the healthy aging, namely through the maintenance of the functional capacity by valuing the autonomy, physical independence and the mental integrity of the elderly person. The challenge of enabling the process of a successful and active aging lays in maximazing the capabilities, potencialities and personal, communitary and political resources. It infers additionaly a broad view of living, contextualized in the continuum of life, able to express concern with health and well-being, integrating the people in aging phase to the context of the life cycle. Hence, this research aimed to learn the determinants of active and successful aging in a population in aging process and relate them with the "practices/contents" and "representations/meanings" about aging, the physical activities and functional capacity. The investigation was structured in three studies: in the first it was developed and tested the instrument "Active Aging, Functional Capacity and Physical Activity" in the city of Lisboa, Portugal, and afterwards it was culturally and linguistically adapted from Portugal Portuguese to Brazilian Portuguese. The second study was an observational research with survey, descriptive and exploratory methods which aimed to learn the relations established between the successful aging, active aging, the physical activity and the functional capacity of a population in aging process; and the third comprised a qualitative study with the objective to collect the understanding and behavior of the interviewees based on the fact of either they saw themselves as elder or aged person or not. As theoretical framework were explored: active aging, successful aging, multidimensional concept of aging process (personal, familial, social, psycho-communicational, economic determinants), physical activity and functional capacity and explored based in demographic profile and in the European, American a Brazilian realities. Performed triangulation of methods and tecniques (recorded individual interviews, measurements and questionnaires). Participants were aged 60 or older included in two public services for the elderly population in the city of Juiz de Fora, Minas Gerais, Brazil and were excluded persons with dependency in both daily activities and instrumental daily activities and the persons with altered level of conciousness. Stratified ramdon sample of 326 participants in which were performed the measurements and typicality sample constructed from the sample basis of 87 participants whereupon the recorded individual interview was performed. Conforming to all the ethical and legal requirements of research with human beings according to the Brazilian legislation. Applied Factor Analysis and selected 11 factors and 31 variables that convey the determinants of the active aging process. Executed reajustment of factor analysis, for conceptual coherence, being selected eight factors named accordingly to the theoretical framework that resulted in 25 variables which approached the participation in activities and access to health care services; to physical activity; to coexistence, interaction and evaluation of social contact; to scholarity and income; to perceived health and volunteering. Used as marker to aerobic activity the profile of weekly physical activity overload in accordance with guidelines and reccomendations for moderate-intensity aerobic activities for older people. Identified that 60,7% of interviewees practice enough physical activity. Anthropometric markers evidence overweight and obesity levels both within men and women. There was correlation between body mass index (BMI) and measures carried out according to age ranges. The inferential analysis allowed relating the active aging determinants, the anthropometric measurements and sociodemographic variables (scholarity and age), obtaining the following highlights: 1) to the extent that age increases, lowers the levels of physical activity practice, of contact with people to talk to (social relationships), of volunteering work and familial and intergenerational relationships; 2) it was identified a conceptual alignment of diferent determinants concurrent to an active aging in light of the physical activity practice with the relationship and interaction of family and with positive self-assessment of perceived health and physical activity; 3) the older the person, lower are scholarity levels; 4) the decrease of the cross-sectional area of the arm and BMI as the age increases portrayed decreased adiposity of the body that is associated with loss of lean body mass. The categorization of the speech of 87 interviewees allowed to collect the understanding of the aging process by two opposite criteria: preservation of autonomy and existance of decline. It marked the belief system of participants with 1090 beliefs expressed. With tendency of the belief system to centrality with 638(58,6%) beliefs showing concepts and dificult situations to be changed through educational processes. The results diagnosed and reiterated the tendency of increase in the number of people aged 60 or older in the Brazilian city of Juiz de Fora. Although the elderly statute is built upon principles of healthy and active aging it was evident the need of strategies to implement it aiming at social, economic and health impacts in the perspective of physical education and preservation of the functional capacity. Constitute contributions of this study: 1) theoretical fundaments and data about Juiz de Fora citizens aged 60 or more according to social, economic, cultural and spiritual dimensions in a broad concept of health; 2) approach of aging in a procedural and integrative, multidimensional manner, articulated with the life cycle; 3) diagnosis of degree of autonomy of participants enabling decisions on how to improve their functional capacities; 4) investigative process using theoretical models which permit to stablish a local diagnosis and contextualize the aging process of participants and 5) weekly overload of physical activity and anthropometric indexes of participants as to subsidize parameters to therapeutic indication to the maintainence of functional capacity.

Are vectors able to learn about their hosts? A case study with Aedes aegypti mosquitoes

The way in which vectors distribute themselves amongst their hosts has important epidemiological consequences. While the role played by active host choice is largely unquestioned, current knowledge relates mostly to the innate response of vectors towards stimuli signalling the presence or quality of their hosts. Many of those cues, however, can be unpredictable, and therefore prevent the incorporation of the appropriate response into the vector's behavioural repertoire unless some sort of associative learning is possible. We performed a wide range of laboratory experiments to test the learning abilities of the mosquito, Aedes aegypti. Mosquitoes were exposed to choice procedures in (1) an olfactomenter and (2) a 'visual arena'. Our goal was to determine whether the mosquitoes were able to associate unconditional stimuli (blood feeding, human breath, vibration and electrical shock) with particular odours (citral, carvone, citronella oil and eugenol) and visual patterns (horizontal or vertical black bars) to which they had been previously observed to be responsive. We found no evidence supporting the hypothesis that associative learning abilities are present in adult Ae. aegypti. We discuss the possibilities that the assays employed were either inappropriate or insufficient to detect associative learning, or that associative learning is not possible in this species.

Changing the future: experiencing adolescence in contemporary Ireland: sexual health and behaviour.

If we create the space in which children and young people can talk openly and in their own language even upon challenging subjects such as sex, then we are likely to learn more from what they tell usâ?T proposes the final UNICEF Ireland report which examines adolescent perspectives on sexual health and behaviour. Key findings in the report included: 63%, and 1 in 5 sixteen year old respondents, reported that they have had sex; 1 in 5 sexually active respondents reported that they did not use a condom the first time that they had sex; 2 in 5 girls who were sexually active reported that they had consumed alcohol before their first sexual experience, compared to 3 in 10 boys; The majority of respondents (54%) reported that they had watched pornography on the internet, and more than one third of the respondents who had watched pornography on the internet believed that it was accurate or educational; Only 1 in 5 respondents reported that they ever speak to their parents about sex. Noting â?~the broad spectrum from which young people living in Ireland draw down information about sexâ?T the UNICEF Ireland report concludes that â?~we must be sure that when a young person is making decisions about their sexual health and behaviour, every opportunity is afforded them in terms of open discussion, understanding, support, information and adviceâ?T Commenting on the Report, Amel Yucef a Youth Health Coordinator at the Base Youth Centre, Ballyfermot said â?oAs the participants in UNICEF Irelandâ?Ts survey have shown, many young people do not feel equipped with the information and support they need to make informed choices about their sexual health. Providing those supports is a priority for us at the Base.â? The Youth Health Programme, that Amel co-ordinates is a HSE funded initiative which was created to respond to the health needs of young people, as identified by the young people of the Dublin 10 area themselves. The Programme delivers community-based and youth-friendly health responses, based upon a harm-reduction model. The Youth Health Programme works towards building the capacity of young people to access health services, while also encouraging those services to deliver in an accessible and youth-friendly way.This resource was contributed by The National Documentation Centre on Drug Use.

More about the role of 2,6-dichlorophenol in tick courtship: identification and olfactometer bioassay in Amblyomma cajennense and Rhipicephalus sanguineus

This study aimed to identify 2,6-dichlorophenol (2,6-DCP) in Amblyomma cajennense and to evaluate its role in A. cajennense and Rhipicephalus sanguineus courtship. Hexanic extract from attractive females was purified by solid phase extraction and the phenol was identified by the single ion monitoring method using GC/MS. In an olfactometer, the responses of A. cajennense and R. sanguineus males to females, control rubber septa or rubber septa impregnated with 2,6-DCP at 50, 500, and 5000 ng, respectively, were studied. 2,6-DCP was identified in A. cajennense extract and the males oriented themselves toward the concentration of 500 ng. These septa and the females were recognized as copula partners. The septa treated with 2,6-DCP did not attract and were not even recognized by the R. sanguineus males, whereas the females were recognized. Due to the presence of 2,6-DCP in A. cajennense and the results of biological bioassays, it was concluded that this compound acts as an attractant and mounting sex pheromone in this tick, but it does not play any role in R. sanguineus courtship.
