Usability in product design--the importance and need for systematic assessment models in product development--Usa-Design Model (U-D) ©

In product design, human factors are considered as an element of differentiation given that today's consumer demands are increasing. Safety, wellbeing, satisfaction, health, effectiveness, efficiency, and other aspects must be effectively incorporated into the product development process. This work proposes a usability assessment model that can be incorporated as an assessment tool. The methodological approach is settled in two stages. First a literature review focus specifically on usability and developing user-centred products. After this, a model of usability named Usa-Design (U-D?) is presented. Consisted of four phases: understanding the use context, pre-preliminary usability assessment (efficiency/effectiveness/satisfaction); assessment of usability principles and results, U-D? features are modular and flexible, allowing principles used in Phase 3 to be changed according to the needs and scenario of each situation. With qualitative/quantitative measurement scales of easy understanding and application, the model results are viable and applicable throughout all the product development process.     

Positive Identity Experiences of Young Bisexual and Other Nonmonosexual People: A Qualitative Inquiry

The majority of LGBTQ psychological research focuses on dysfunction. The exclusion of strengths-based perspectives in LGBTQ psychology limits the understanding of LGBTQ mental health. In this article we report experiences that young bisexual and other nonmonosexual people perceive as affirming of their sexual identity. A 28-day, daily diary study was used to investigate whether bisexual-identified participants encountered positive experiences related to their sexual identity, and which type of experiences they perceived to be positive. Using a constructivist grounded theory approach, participants’ experiences were organized according to a social ecological model. Experiences were reported at the intrapersonal, interpersonal, and institutional levels, but most positive sexual identity experiences occurred at the interpersonal level. Implications for positive health outcome research and the integration of positive psychology with LGBTQ psychology are discussed, as well as study limitations.     

Post-Traumatic Stress Disorder,Dissociation, and Neuropsychological Performance in Latina Victims of Childhood Sexual Abuse

This study compared the memory, attention/concentration, and executive functioning of 12 women with histories of child sexual abuse with a control group of 12 women without childhood abuse. Participants completed a neuropsychological test battery and various instruments assessing post-traumatic stress disorder and dissociation. The child sexual abuse group had lower performance than the control group on long- and short-term visual and verbal memory and presented more limited performance on executive functioning tasks. Functioning in these areas showed a negative correlation with post-traumatic stress disorder and dissociative symptoms. These findings suggest that child sexual abuse is associated with memory and executive functioning deficits and supports the idea that people with trauma histories and increased post-traumatic stress disorder and dissociation symptoms may have alterations in neuropsychological functioning.     

All I Need is Shoe: An Investigation into the Obligatory Aspect of Sexual Object Fetishism

Using a mixed-methods approach, the authors explored whether individuals reporting sexual object fetishism require the presence of their fetish for sexual activity. In Study 1 (n = 63), a qualitative study, the majority of participants reported enjoying sexual activity without the fetishized object. However, sexual activities involving their fetish were preferred. In Study 2 (n = 195), the majority of participants reported having engaged in both fetish and nonfetish sexual activities, and that the fetish was not required for sexual arousal. On average, both fetish and nonfetish sexual activity were rated as sexually satisfying, although fetish sex was rated as more satisfying.     

Fostering democracy through social media: Evaluating diametrically opposed nonprofit advocacy organizations’ use of Facebook,Twitter, and YouTube

Nonprofit organizations contribute to a democratic society by allowing those with diverse opinions to assemble and voice these ideas. Social media has provided an extensive new marketplace in which such organizations can give voice to their ideas. Thus the purpose of this study was to explore and assess the use of social media (Facebook, Twitter, and YouTube) for advocacy by nonprofit organizations with diametrically opposed points-of-view on two social issues, the pro-gun/gun control issue and the pro-choice/pro-life issue. Results of this study indicate that nonprofit advocacy organizations are using social media to ethically persuade people to their point of view, for the most part through use of one-way communication. Moreover, organizations are using the various social media for different purposes, providing thanks and recognition on Twitter, and soliciting feedback and other two-way communication with stakeholders on Facebook. Use of authority figures to communicate messages is generally reserved for YouTube.     

Genetic diversity and relatedness of a recently established population of eastern coyotes (Canis latrans) in New York City

Little is known about the relatedness structure of carnivores living in urban areas, where green spaces may vary in size and resource availability. We examined the minimum population size, relatedness structure, and genetic diversity of a recently established population of eastern coyotes (Canis latrans) inhabiting New York City (NYC). The population has been established for approximately 25 years, and sample collection for genetic analysis has been ongoing since 2010. We genotyped 234 scat, eight tissue, and three blood samples at nine microsatellite loci. We identified 45 individual coyotes with a male-biased sex ratio of 2.2:1. We also found moderate to high levels of genetic diversity, with average observed heterozygosity of 0.779 and mean number of alleles per locus of 7.8. Most of the green spaces surveyed supported a single group of closely related coyotes in each. Relatedness comparisons between parks also indicated that coyotes compared across different parks were also closely related. We identified two unrelated mated pairs and found no support for polygamy. The high incidence of relatedness suggests that the coyote population is descended from a small number of founding individuals. Additionally, we genetically recaptured several coyotes, including one individual sampled in the Bronx and in Queens, with a median of 103 days between resampling. This result indicates that the coyotes are persisting in some of the isolated greenspaces of New York City and able to move successfully between them.
