ADOPTING IDENTITIES: ASSOCIATIONS BETWEEN ADOPTION, RACIAL-ETHNIC, AND SEXUAL MINORITY PARENT SOCIALIZATION AND CHILDREN’S ATTACHMENT, GLOBAL SELF-WORTH, AND UNDERSTANDING OF IDENTITY

Utilizing a sample of lesbian, gay, and heterosexual adoptive parent families with school-age children, results suggested that parents engage in adoption communication less but racial-ethnic socialization more when a child is transracially adopted. No differences were found in lesbian and gay parents socialization practices for adoptive or racial-ethnic identity. Further, lesbian and gay parents engaged in sexual minority parent socialization less than adoptive or racial-ethnic socialization. Children’s self-worth was related to sex but not socialization practices such that girls reported lower self-worth, and no significant associations were present for children’s closeness. Children’s age, sex, and transracial adoptive status were predictive of their understanding of adoption and only children’s age was predictive of their recognition of sexual minority parent socialization. Children’s sex and transracial adoptive status as predictors of understanding of adoption have not yet been reported on in the literature. Further, no work has reported on associations between parent and child socialization practices in the context of sexual minority parent socialization. The implications of differences emerging in parent socialization frequency (i.e., racial-ethnic communication higher than adoptive communicative openness), as well as how children’s sex and transracial adoptive status contribute to children’s understanding of adoption will be discussed

How are normal sleeping controls selected? A systematic review of cross-sectional insomnia studies, and a standardised method to select healthy controls for sleep research

There appears to be some inconsistency in how normal sleepers (controls) are selected and screened for participation in research studies for comparison with insomnia patients. The purpose of the current study is to assess and compare methods of identifying normal sleepers in insomnia studies, with reference to published standards. We systematically reviewed the literature on insomnia patients which included control subjects. The resulting 37 articles were systematically reviewed with reference to the five criteria for normal sleep specified by Edinger et al. (2004). In summary, these criteria are: evidence of sleep disruption; sleep scheduling; general health; substance/medication use; and other sleep disorders. We found sleep diaries, PSG, and clinical screening examinations to be widely used with both control subjects and insomnia participants. However, there are differences between research groups in the precise definitions applied to the components of normal sleep. We found that none of reviewed studies applied all of the Edinger et al. criteria, and 16% met four criteria. In general, screening is applied most rigorously at the level of a clinical disorder, whether physical, psychiatric, or sleep. While the Edinger et al. criteria seem to be applied in some form by most researchers, there is scope to improve standards and definitions in this area. Ideally, different methods such as sleep diaries and questionnaires would be used concurrently with objective measures to ensure normal sleepers are identified, and descriptive information for control subjects would be reported. Here, we have devised working criteria and methods to be used for assessment of normal sleepers. This would help clarify the nature of the control group, in contrast to insomnia subjects and other patient groups

Social interactions, emotion and sleep: a systematic review and research agenda

Sleep and emotion are closely linked, however the effects of sleep on socio-emotional task performance have only recently been investigated. Sleep loss and insomnia have been found to affect emotional reactivity and social functioning, although results, taken together, are somewhat contradictory. Here we review this advancing literature, aiming to 1) systematically review the relevant literature on sleep and socio-emotional functioning, with reference to the extant literature on emotion and social interactions, 2) summarize results and outline ways in which emotion, social interactions, and sleep may interact, and 3) suggest key limitations and future directions for this field. From the reviewed literature, sleep deprivation is associated with diminished emotional expressivity and impaired emotion recognition, and this has particular relevance for social interactions. Sleep deprivation also increases emotional reactivity; results which are most apparent with neuro-imaging studies investigating amygdala activity and its prefrontal regulation. Evidence of emotional dysregulation in insomnia and poor sleep has also been reported. In general, limitations of this literature include how performance measures are linked to self-reports, and how results are linked to socio-emotional functioning. We conclude by suggesting some possible future directions for this field

The Sleep Condition Indicator: a clinical screening tool to evaluate insomnia disorder

Objective: Describe the development and psychometric validation of a brief scale (the Sleep Condition Indicator (SCI)) to evaluate insomnia disorder in everyday clinical practice.<p></p> Design: The SCI was evaluated across five study samples. Content validity, internal consistency and concurrent validity were investigated.<p></p> Participants: 30 941 individuals (71% female) completed the SCI along with other descriptive demographic and clinical information.<p></p> Setting: Data acquired on dedicated websites.<p></p> Results: The eight-item SCI (concerns about getting to sleep, remaining asleep, sleep quality, daytime personal functioning, daytime performance, duration of sleep problem, nights per week having a sleep problem and extent troubled by poor sleep) had robust internal consistency (α≥0.86) and showed convergent validity with the Pittsburgh Sleep Quality Index and Insomnia Severity Index. A two-item short-form (SCI-02: nights per week having a sleep problem, extent troubled by poor sleep), derived using linear regression modelling, correlated strongly with the SCI total score (r=0.90).<p></p> Conclusions: The SCI has potential as a clinical screening tool for appraising insomnia symptoms against Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) criteria.<p></p&gt

Per-host DDoS mitigation by direct-control reinforcement learning

DDoS attacks plague the availability of online services today, yet like many cybersecurity problems are evolving and non-stationary. Normal and attack patterns shift as new protocols and applications are introduced, further compounded by burstiness and seasonal variation. Accordingly, it is difficult to apply machine learning-based techniques and defences in practice. Reinforcement learning (RL) may overcome this detection problem for DDoS attacks by managing and monitoring consequences; an agent’s role is to learn to optimise performance criteria (which are always available) in an online manner. We advance the state-of-the-art in RL-based DDoS mitigation by introducing two agent classes designed to act on a per-flow basis, in a protocol-agnostic manner for any network topology. This is supported by an in-depth investigation of feature suitability and empirical evaluation. Our results show the existence of flow features with high predictive power for different traffic classes, when used as a basis for feedback-loop-like control. We show that the new RL agent models can offer a significant increase in goodput of legitimate TCP traffic for many choices of host density

Family Conflict Observations and Outcomes among Adopted School-Age Children with Lesbian, Gay, and Heterosexual Parents

Children’s externalizing problems are associated with family conflict among children and their biological parents, yet these linkages have remained unexamined among adoptive or lesbian and gay parent families. Investigating family processes facilitative of adjustment among adoptees, who face unique developmental challenges, is warranted. This multimethod study of 96 (26 lesbian, 29 gay, 41 heterosexual parent) adoptive families examined observations of adoptive family conflict and associations with child adjustment and feelings about adoption (children’s Mage = 8 years). The sample was recruited from 5 private, domestic infant adoption agencies across the United States. Parents and children reported about children’s externalizing problems and feelings about adoption, respectively. Observations of family conflict interaction were rated from videotaped family discussions. Family interactions were associated with children’s behavioral and adoption-specific adjustment, yet analysis of variance and hierarchical linear modeling analyses revealed no differences by parental sexual orientation in family dynamics (i.e., negativity/conflict, positive affect, cohesiveness) or child outcomes. Parents generally reported children to have few externalizing behaviors. Children reported positive feelings, moderate preoccupation, and low negativity about their adoption. These findings extend the family systems literature about conflict and child development among diverse families with sexual minority parents and adopted children. Practitioners who work with adoptive and sexual minority parent families can encourage positive and cohesive family interactions in supporting children’s adjustment.

Sport Management Internship Quality and the Development of Political Skill: A Conceptual Model

Internships are a key component of sport organizations and the sport management curriculum. Due to the vastness of internships both in academia and the sport profession, it is imperative to understand the effectiveness of internships for both the organization and the intern. While previous research has focused on quality control, the agency’s perspective of internships, the student’s perspective, and how to link the theory to practice, scholars have yet to examine the effects of sport management internships on the development of essential professional skills and/or attributes. Given the political nature of obtaining and keeping a job in the sport business, the purpose of this paper is to propose a conceptual model that allows the effectiveness of a sport management internship to be evaluated according to its effect on the political skill of interns. Understanding the internship as one component of the sport management curricula, the conceptual model links sport management students’ developmental experiences, and internship quality to the development of political skill, and three secondary outcomes (i.e., domain-specific self-efficacy, sport industry identification, and future employment intentions). In doing so a comprehensive method for evaluating the effectiveness of internships that prioritizes the student’s growth is offered

Exploring Student Persistence in STEM Programs: A Motivational Model

To address continually decreasing enrollment and rising attrition in post-secondary STEM degree (science, technology, engineering, and mathematics) programs, particularly for women, the present study examines the utility of motivation and emotion variables to account for persistence and achievement in science in male and female students transitioning from high school to junior college. Consistent with self-determination theory (Deci & Ryan, 2012) and achievement-goal theory (Senko, Hulleman, & Harackiewicz, 2011),structural equation modelling based on data from 1,309 students from four English-language CEGEPs showed students’ achievement goals, self-efficacy, and perceived autonomy support to impact intrinsic motivation, emotions, and achievement that, in turn, predicted persistence in the science domain

Preventing Supply Chain Vulnerabilities in Java with a Fine-Grained Permission Manager

Integrating third-party packages accelerates modern software engineering, but introduces the risk of software supply chain vulnerabilities. Vulnerabilities in applications' dependencies are being exploited worldwide. Often, these exploits leverage features that are present in a package, yet unneeded by an application. Unfortunately, the current generation of permission managers, such as SELinux, Docker containers, and the Java Security Manager, are too coarse-grained to usefully support engineers and operators in mitigating these vulnerabilities. Current approaches offer permissions only at the application's granularity, lumping legitimate operations made by safe packages with illegitimate operations made by exploited packages. This strategy does not reflect modern engineering practice. we need a permission manager capable of distinguishing between actions taken by different packages in an application's supply chain. In this paper, we describe Next-JSM, the first fine-grained ("supply chain aware") permission manager for Java applications. Next-JSM supports permission management at package-level granularity. Next-JSM faces three key challenges: operating on existing JVMs and without access to application or package source code, minimizing performance overhead in applications with many packages, and helping operators manage finer-grained permissions. We show that these challenges can be addressed through bytecode rewriting; appropriate data structures and algorithms; and an expressive permission notation plus automated tooling to establish default permission. In our evaluation, we report that Next-JSM mitigates 11 of the 12 package vulnerabilities we evaluated and incurs an average 2.72% overhead on the Dacapobench benchmark. Qualitatively, we argue that Next-JSM addresses the shortcomings of the (recently deprecated) Java Security Manager (JSM).Comment: 15 pages, 5 figures, 5 table
