Despite the growing visibility and acceptance of transgender and gender nonconforming (TGNC) individuals, TGNC older adults experience many barriers in accessing competent and affirming health and ...social services due to anti-TGNC prejudice, discrimination, and lack of competent healthcare training on the part of healthcare workers. Clinical gerontologists and geriatricians will likely encounter TGNC adults in their practice given population aging and greater numbers of TGNC people who are living in their affirmed gender identities. The American Psychological Association recently published its Guidelines for Psychological Practice with Transgender and Gender Nonconforming People, which document the unique needs of TGNC individuals and outlines approaches for competent and affirming service provision (APA, 2015). We interpret these Guidelines using a gerontological lens to elucidate specific issues faced by the TGNC older adult along with the practice and policy implications for this population.
Transgender and gender nonconforming (TNGC) clients have complex mental health concerns, and are more likely than ever to seek out treatment. Written by a team of psychologists and TNGC specialists, ...this comprehensive resource outlines the latest research and recommendations to provide clinicians with the requisite knowledge, skills, and awareness to treat these clients with competent and affirming care.
In this article, the authors discuss the unique considerations that psychologists may keep in mind when working with transgender and gender nonconforming (TGNC) clients of color. These considerations ...are informed by the Guidelines for Psychological Practice with Transgender and Gender Nonconforming Clients (American Psychological Association, 2015). The major components of TGNC-affirmative psychological practice with TGNC people of color are described, including (a) interrogating psychologist race/ethnicity and gender identity, (b) addressing the intersectionality of race/ethnicity and gender identity, (c) challenging assumptions about TGNC experiences and the experiences of people of color, (d) building rapport and acknowledging differences within the therapeutic dyad, (e) assessing client strengths and resilience in navigating multiple oppressions, and (f) providing a variety of resources that are affirming to TGNC people of color. A case vignette is provided that explores these components and brings them to life.
By using unique individual-level data, this study investigates information asymmetry in reinsurance contracts ceded by commercial fire insurance contracts in Taiwan. The significantly negative ...conditional correlation between the ceded portion and claim probability in reinsurance contracts indicates no information asymmetry in the reinsurance market. However, when analyzing reinsurance through various ceding methods and ceding layers, there is evidence of information asymmetry in reinsurance contracts ceded through treaty agreements emerges when claims reach higher ceding layers. In lower ceding layers, the evidence of information asymmetry does not emerge, but the force of adverse selection and/or moral hazard are stronger in facultative reinsurance than in treaty reinsurance. When the ceding layer increases, this relative force alternates between treaty agreement and facultative agreement. These results indicate that information asymmetry effects exist but may be attenuated by various factors. For example, insurers may be strongly motivated to maintain long-term good relationships with reinsurers, and reinsurers may possess superior information that enables them to underwrite and audit effectively. Our findings also align with those in the literature, indicating that multilayer reinsurance treaties can mitigate information asymmetry.
•This paper is the first study using individual level data to explore the problem of information asymmetry for the single line of the reinsurance of commercial fire insurance by the conditional relationship between the ceded portion and risk of reinsurance contracts after the observable information are controlled for.•Information asymmetry may differ across reinsurance agreements and reinsurance layers. Only individual contract data can provide information regarding ceding agreements and information regarding ceding layer in each ceded contract, and support our empirical investigation of whether information asymmetry differs between facultative and treaty reinsurance agreements and between reinsurance layers.•Although we found no information asymmetry in the reinsurance market, the force of adverse selection and/or moral hazard are stronger in facultative reinsurance than in treaty reinsurance in lower ceding layers, and there is evidence of information asymmetry in reinsurance contracts ceded through treaty agreements emerges when claims reach higher ceding layers.•Our empirical findings also have several implications for insurance practice. To address the problem of information asymmetry in the reinsurance market, reinsurers should focus on treaty agreements. First, the long-term relationships between insurers and reinsurers play a key role in mitigating the information asymmetry in reinsurance market, and treaty agreements are highly suitable for forming such relationships. Second, information asymmetry can also be alleviated through multilayer reinsurance treaties. Information asymmetry does not exist in lower layers but emerges in higher layers, which may the layers above the optimal layer.
Context. Super-luminous supernovae (SLSNe) are rare events defined as being significantly more luminous than normal terminal stellar explosions. The source of the additional power needed to achieve ...such luminosities is still unclear. Discoveries in the local Universe (i.e. z < 0.1) are scarce, but afford dense multi-wavelength observations. Additional low-redshift objects are therefore extremely valuable. Aims. We present early-time observations of the type I SLSN ASASSN-18km/SN 2018bsz. These data are used to characterise the event and compare to literature SLSNe and spectral models. Host galaxy properties are also analysed. Methods. Optical and near-IR photometry and spectroscopy were analysed. Early-time ATLAS photometry was used to constrain the rising light curve. We identified a number of spectral features in optical-wavelength spectra and track their time evolution. Finally, we used archival host galaxy photometry together with H II region spectra to constrain the host environment. Results. ASASSN-18km/SN 2018bsz is found to be a type I SLSN in a galaxy at a redshift of 0.0267 (111 Mpc), making it the lowest-redshift event discovered to date. Strong C II lines are identified in the spectra. Spectral models produced by exploding a Wolf-Rayet progenitor and injecting a magnetar power source are shown to be qualitatively similar to ASASSN-18km/SN 2018bsz, contrary to most SLSNe-I that display weak or non-existent C II lines. ASASSN-18km/SN 2018bsz displays a long, slowly rising, red “plateau” of >26 days, before a steeper, faster rise to maximum. The host has an absolute magnitude of –19.8 mag (r), a mass of M⋆ = 1.5−0.33+0.08 × 109 M⊙ M ⋆ = 1.5 − 0.33 + 0.08 × 10 9 M ⊙ $ M_\star=1.5_{-0.33}^{+0.08}\times10^9M_\odot $ , and a star formation rate of = 0.50−0.19+2.22 M⊙ yr −1 = 0.50 − 0.19 + 2.22 M ⊙ yr − 1 $ =0.50_{-0.19}^{+2.22}M_\odot\text{yr}^{-1} $ . A nearby H II region has an oxygen abundance (O3N2) of 8.31 ± 0.01 dex.

We describe the protocol through which we identify and characterize dynein subunit genes in the ciliated protozoan Tetrahymena thermophila. The gene(s) of interest is found by searching the ...Tetrahymena genome, and it is characterized in silico including the prediction of the open reading frame and identification of likely introns. The gene is then characterized experimentally, including the confirmation of the exon-intron organization of the gene and the measurement of the expression of the gene in nondeciliated and reciliating cells. In order to understand the function of the gene product, the gene is modified-for example, deleted, overexpressed, or epitope-tagged-using the straightforward gene replacement strategies available with Tetrahymena. The effect(s) of the dynein gene modification is evaluated by examining transformants for ciliary traits including cell motility, ciliogenesis, cell division, and the engulfment of particles through the oral apparatus. The multistepped protocol enables undergraduate students to engage in short- and long-term experiments. In our laboratory during the last 6 years, more than two dozen undergraduate students have used these methods to investigate dynein subunit genes.
Genetic gain and diversity (status number) were estimated in a 12-year-old
Quercus accutissima seedling seed orchard under three thinning scenarios. These scenarios were based on linear (ranged from ...the removal of individuals within families to the removal of entire families based on the family genetic values generated from conventional progeny test trials), systematic (removal of every second row), and truncation (families with genetic values below the specific threshold value were totally removed) thinning. Both genetic gain and diversity of each scenario were estimated and compared to those of before thinning. Truncation thinning produced the highest genetic gain that was coupled with the lowest diversity, while linear thinning produced the moderate balance between genetic gain and diversity. Systematic thinning, on the other hand, produced the lowest genetic gain and the highest diversity. Under the linear thinning option, the number of family completely removed was minimized to keep up options for further genetic evaluation and selection. This linear thinning was accomplished by applying within family thinning regime that was proportionate to the reverse of every family genetic gain (i.e., low numbers of trees removed from high genetic value families and higher numbers of trees removed from lower genetic value families).
