Obscenity on the Internet: Nationalizing the Standard to Protect Individual Rights
This note was written in response to the Ninth Circuit Court of Appeals\u27 2009 decision in United States v. Kilbride. The Court\u27s opinion called for the application of a national obscenity standard when evaluating speech transmitted online or through e-mail. This note seeks to address some of the practical issues raised by a national standard, including identifying the relevant national community, the need for empirical research on community standards for obscenity, implications for free speech under a national standard and mechanisms to ensure consistent application of a national standard in a diverse country
Identifying individual, partner, household, and neighborhood predictors of intimate partner violence among poor Ecuadorian and Colombian refugee women: A multi-level analysis
Intimate partner violence (IPV) effects a third of South American women and results in significant health and social consequences. Previous research on IPV has relied heavily on cross-sectional data and focused almost exclusively on the characteristics of the woman, ignoring important contextual factors. South America has experienced mass migration due to the recently-ended internal conflict in Colombia, and current instability in Venezuela. The region has simultaneously undergone rapid shifts regarding women’s rights. Using multilevel logistic regression on a longitudinal sample of 1312 poor Ecuadorian and Colombian women living in northern Ecuador, I explored predictors of recent emotional and physical and/or sexual IPV through two related theoretical lenses—social disorganization theory (aim 1) and feminist theory (aim 2). In the sample, 29.4% and 15.6% of women reported recent emotional and physical and/or sexual IPV, respectively. In the Aim 1 analysis, neighborhood social disorganization was marginally, positively associated with emotional IPV (AOR: 1.17, 95% CI: 0.99, 1.38) and trended in the same direction for physical and/or sexual IPV (AOR: 1.20, 95% CI: 0.96, 1.51). Mediation analysis suggest that higher social disorganization is associated with lower neighborhood-level civic engagement (AOR: 0.94, 95% CI: 0.91, 0.98) and higher neighborhood-level civic engagement is associated with lower odds of emotional IPV (AOR: 0.35, 95% CI: 0.13, 0.93). In the Aim 2 analysis, females' increasing participation in household decision-making between time 1 and time 2, at both the household and neighborhood-level, was negatively associated with emotional and physical and/or sexual IPV at time 2, respectively. Having lower education than their partner was a risk factor for IPV (emotional: AOR: 1.71, 95% CI: 1.22, 2.42; physical and/or sexual IPV: AOR: 1.57, 95% CI: 1.08, 2.28). Indicators of economic empowerment were not associated with IPV outcomes in the expected direction. Results support investing in strategies to increase women’s participation and achievement in higher education, and shifting gender norms to create more equitable households and neighborhoods. As South America, and other parts of the world, experience unprecedented mass migration, this research also underscores the importance of integrating IPV prevention and response programs into services in conflict-affected areas and host communities.Doctor of Philosoph
A Mixed-Methods Systematic Review: Infidelity, Romantic Jealousy and Intimate Partner Violence against Women.
Infidelity and romantic jealousy (RJ) are commonly cited relational level drivers of intimate partner violence (IPV) but remain undertheorized and underutilized in IPV research and prevention. This global systematic review aims to characterize the existing research on real or suspected infidelity and RJ in relation to IPV and inform future research and programming. We systematically searched 11 databases for peer-reviewed research, published between April 2009 and 2019, that provided data on the prevalence or a measure of association (quantitative), or pathway (qualitative), between real or suspected infidelity or RJ, and IPV. Fifty-one papers from 28 countries were included and the evidence showed a consistent association between real or suspected infidelity, RJ and IPV. Our findings identify three overarching mechanisms and six pathways between infidelity, RJ and IPV. These provide support for prominent theories in the field related to patriarchal culture, threatened masculinities and femininities and a lack of emotional regulation and conflict resolution skills, but not evolutionary theories. Our findings suggest that researchers should use standardized measurement tools that make the distinction between RJ and suspected, confirmed and accusations of infidelity. Policy and programming should aim to transform traditional gender roles, accounting for infidelity and RJ and improving couple's communication and trust

Intimate partner violence against women on the Colombia Ecuador border: a mixed-methods analysis of the liminal migrant experience.
BACKGROUND: Intimate partner violence (IPV) has serious long-term health and psychological consequences and is highly prevalent in Latin America and among displaced populations. Liminality - the ambiguous in-between state of individuals completing a migratory journey - represents a state of legal, economic, and physical insecurity. Through the framework of liminality, this analysis seeks to understand the unique challenges faced by displaced Colombian women in Ecuador including their experience of IPV. METHODS: We performed a secondary analysis of 15 in-depth interviews and 319 longitudinal surveys, conducted on the border of Ecuador and Colombia, following a sequential explanatory mixed-methods design. We analysed interviews thematically and mapped the main themes onto complementary quantitative variables. We conducted logistic regression with identified risk and protective factors (measured at time 1) and recent IPV (measured at time 2), controlling for demographic characteristics and IPV at time 1. RESULTS: Our mixed-methods analysis revealed four main mechanisms by which displacement influenced the social and economic realities of Colombian women years after crossing the border, compounding their risk of IPV and limiting their ability to escape it. Lack of legal residence and documentation, violence experienced along life course and migratory continuums which increased their risk for later revictimisation, social isolation including loss of support networks and restricted mobility and lastly, financial stress. CONCLUSIONS: This research highlights the critical importance of supporting the economic and social integration of migrants and refugees in host communities, as well as the need to carefully consider migration-related vulnerabilities in IPV prevention and response interventions. As the regional refugee crisis grows, policy makers must consider how the long-term marginalisation of refugee women contributes to their victimisation. This research also supports the idea of incorporating gender synchronised, transformative IPV prevention and response programmes into migration-related and poverty alleviation international development efforts
The role of gender and romantic jealousy in intimate partner violence against women, a mixed-methods study in Northern Ecuador.
Male romantic jealousy is a commonly cited driver of intimate partner violence against women. An in-depth, contextualised understanding of the pathways and mechanisms from jealousy to intimate partner violence is, however, needed to inform programmes and interventions. We triangulated data from 48 interviews, eight focus groups and 1216 survey findings from low-income married women and men in northern Ecuador. Male jealousy was associated with controlling behaviours (aOR: 14.47, 95% CI: 9.47, 22.12) and sexual intimate partner violence (aOR: 2.4, 95% CI: 1.12, 5.12). Controlling behaviours were associated with physical and sexual intimate partner violence (aOR: 2.16, 95% CI: 1.21, 3.84). Qualitatively we found that most respondents framed jealousy within a discourse of love, and three triggers of male jealousy leading to intimate partner violence were identified: (1) community gossip, which acted as a mechanism of community control over women's movements and sexuality; (2) women joining the labour force, which was quantitatively associated with intimate partner violence and partially mediated by jealousy; and (3) women's refusal to have sex, which could lead husbands to coerce sex through accusations of infidelity. Gender-transformative interventions at the individual, couple and community level providing models of alternative masculinities and femininities may offer promise in reducing intimate partner violence in Ecuador. Importantly, future economic empowerment interventions should address jealousy to mitigate potential intimate partner violence backlash
Preferential Generation of 15-HETE-PE Induced by IL-13 Regulates Goblet Cell Differentiation in Human Airway Epithelial Cells
Type 2–associated goblet cell hyperplasia and mucus hypersecretion are well known features of asthma. 15-Lipoxygenase-1 (15LO1) is induced by the type 2 cytokine IL-13 in human airway epithelial cells (HAECs) in vitro and is increased in fresh asthmatic HAECs ex vivo. 15LO1 generates a variety of products, including 15-hydroxyeicosatetraenoic acid (15-HETE), 15-HETE-phosphatidylethanolamine (15-HETE-PE), and 13-hydroxyoctadecadienoic acid (13-HODE). In this study, we investigated the 15LO1 metabolite profile at baseline and after IL-13 treatment, as well as its influence on goblet cell differentiation in HAECs. Primary HAECs obtained from bronchial brushings of asthmatic and healthy subjects were cultured under air–liquid interface culture supplemented with arachidonic acid and linoleic acid (10 μM each) and exposed to IL-13 for 7 days. Short interfering RNA transfection and 15LO1 inhibition were applied to suppress 15LO1 expression and activity. IL-13 stimulation induced expression of 15LO1 and preferentially generated 15-HETE-PE in vitro, both of which persisted after removal of IL-13. 15LO1 inhibition (by short interfering RNA and chemical inhibitor) decreased IL-13–induced forkhead box protein A3 (FOXA3) expression and enhanced FOXA2 expression. These changes were associated with reductions in both mucin 5AC and periostin. Exogenous 15-HETE-PE stimulation (alone) recapitulated IL-13–induced FOXA3, mucin 5AC, and periostin expression. The results of this study confirm the central importance of 15LO1 and its primary product, 15-HETE-PE, for epithelial cell remodeling in HAEC

Which outcomes are most important to people with aphasia and their families? an international nominal group technique study framed within the ICF
PURPOSE: To identify important treatment outcomes from the perspective of people with aphasia and their families using the ICF as a frame of reference.
METHODS: The nominal group technique was used with people with aphasia and their family members in seven countries to identify and rank important treatment outcomes from aphasia rehabilitation. People with aphasia identified outcomes for themselves; and family members identified outcomes for themselves and for the person with aphasia. Outcomes were analysed using qualitative content analysis and ICF linking.
RESULTS: A total of 39 people with aphasia and 29 family members participated in one of 16 nominal groups. Inductive qualitative content analysis revealed the following six themes: (1) Improved communication; (2) Increased life participation; (3) Changed attitudes through increased awareness and education about aphasia; (4) Recovered normality; (5) Improved physical and emotional well-being; and (6) Improved health (and support) services. Prioritized outcomes for both participant groups linked to all ICF components; primary activity/participation (39%) and body functions (36%) for people with aphasia, and activity/participation (49%) and environmental factors (28%) for family members. Outcomes prioritized by family members relating to the person with aphasia, primarily linked to body functions (60%).
CONCLUSIONS: People with aphasia and their families identified treatment outcomes which span all components of the ICF. This has implications for research outcome measurement and clinical service provision which currently focuses on the measurement of body function outcomes. The wide range of desired outcomes generated by both people with aphasia and their family members, highlights the importance of collaborative goal setting within a family-centred approach to rehabilitation. These results will be combined with other stakeholder perspectives to establish a core outcome set for aphasia treatment research. Implications for Rehabilitation Important outcomes for people with aphasia and their families span all components of the ICF. The relevancy and translation of research findings may be increased by measuring and reporting research outcomes which are important to people living with aphasia. The results of this study indicate that important treatment outcomes for people living with aphasia most frequently link to the activity/participation and body function components of the ICF. The outcomes identified in this study suggest a broad role for clinicians working in aphasia rehabilitation. The categories of identified outcomes may be used clinically as a starting point in goal-setting discussions with clients and their families
Estimating actual foot size from a static bare foot print in a White British Population
In forensic intelligence-gathering it would be useful to be able to estimate the size of a perpetrator's foot from a standing bare footprint found at the scene of crime. Currently, the advice is to add a fixed amount to the length of the footprint (typically 1.5 or 2.0 cm), but there is little evidence for this approach. This study used measured footprint and actual foot lengths from 146 participants from the white British student population of a University in the UK. Data were analysed using multiple regression with foot length as the dependent (outcome) variable and footprint length and sex as the independent variable/factor respectively. Sex was not a significant predictor. The regression equation for the best estimate of the foot length is 19.89 + 0.95 × print length ± 8 mm
Organic electrode coatings for next-generation neural interfaces
Traditional neuronal interfaces utilize metallic electrodes which in recent years have reached a plateau in terms of the ability to provide safe stimulation at high resolution or rather with high densities of microelectrodes with improved spatial selectivity. To achieve higher resolution it has become clear that reducing the size of electrodes is required to enable higher electrode counts from the implant device. The limitations of interfacing electrodes including low charge injection limits, mechanical mismatch and foreign body response can be addressed through the use of organic electrode coatings which typically provide a softer, more roughened surface to enable both improved charge transfer and lower mechanical mismatch with neural tissue. Coating electrodes with conductive polymers or carbon nanotubes offers a substantial increase in charge transfer area compared to conventional platinum electrodes. These organic conductors provide safe electrical stimulation of tissue while avoiding undesirable chemical reactions and cell damage. However, the mechanical properties of conductive polymers are not ideal, as they are quite brittle. Hydrogel polymers present a versatile coating option for electrodes as they can be chemically modified to provide a soft and conductive scaffold. However, the in vivo chronic inflammatory response of these conductive hydrogels remains unknown. A more recent approach proposes tissue engineering the electrode interface through the use of encapsulated neurons within hydrogel coatings. This approach may provide a method for activating tissue at the cellular scale, however, several technological challenges must be addressed to demonstrate feasibility of this innovative idea. The review focuses on the various organic coatings which have been investigated to improve neural interface electrodes
