Transmen and transwomen in China: darkness and resilience

2021 Spring.Includes bibliographical references.Anthropologists have studied transgenderism in various cultures and societies; however, few of these studies investigate the topics of identity development, family lives, and transgender community engagement, and their interwoven relationships in a socialist society. In this research, I look at the lives of Chinese transgender people and aim to understand what roles the government, family and domestic transgender community institutions play in their identity development trajectory. I approach this main research question through a contextualized cultural perspective, analyze it within a critical-interpretive medical anthropological framework, and draw from both anthropological and non-anthropological literature that focus on these three themes. Research data is collected through a mixed qualitative methodology, including online and offline participant observation and semi-structured interviews of ten Chinese transwomen, ten Chinese transmen, and three key informants. Findings suggest that for Chinese transgender respondents, their trajectory of realizing, exploring, and living as their identified gender, which is different from their assigned sex/gender, is commonly repressed and stigmatized on an everyday basis within the cisgender male-female binary system in Chinese society. During these processes, acquiring family recognition and building community connection are respondents' vital sources of resilience, which not only consolidate their (trans)gender identification but also facilitate their transitions. Nevertheless, this is not to say that the family and community institutions are immune to the sexist ideology and cisgender prejudice circulating in Chinese society, which can generate distress mixed with their empowering influences on Chinese transgender respondents. Therefore, throughout their identity development trajectory, respondents always have to resort to their own agency to protect and emancipate themselves from both structural discrimination and transnormative discipline that operate within the institutions which are commonly expected to enhance the resiliency of transgender people

Constraints on the Asymptotic Baryon Fractions of Galaxy Clusters at Large Radii

While X-ray measurements have so far revealed an increase in the volume-averaged baryon fractions $f_b(r)$ of galaxy clusters with cluster radii $r$, $f_b(r)$ should asymptotically reach a universal value $f_b(\infty)=f_b$, provided that clusters are representative of the Universe. In the framework of hydrostatic equilibrium for intracluster gas, we have derived the necessary conditions for $f_b(\infty)=f_b$: The X-ray surface brightness profile described by the $\beta$ model and the temperature profile approximated by the polytropic model should satisfy $\gamma\approx2(1-1/3\beta)$ and $\gamma\approx1+1/3\beta$ for $\beta1$, respectively, which sets a stringent limit to the polytropic index: $\gamma<4/3$. In particular, a mildly increasing temperature with radius is required if the observationally fitted $\beta$ parameter is in the range $1/3<\beta<2/3$. It is likely that a reliable determination of the universal baryon fraction can be achieved in the small $\beta$ clusters because the disagreement between the exact and asymptotic baryon fractions for clusters with $\beta>2/3$ breaks down at rather large radii (\ga30r_c) where hydrostatic equilibrium has probably become inapplicable. We further explore how to obtain the asymptotic value $f_b(\infty)$ of baryon fraction from the X-ray measurement made primarily over the finite central region of a cluster. We demonstrate our method using a sample of 19 strong lensing clusters, which enables us to place a useful constraint on $f_b(\infty)$: $0.094\pm0.035 \leq f_b(\infty) \leq 0.41\pm0.18$. An optimal estimate of $f_b(\infty)$ based on three cooling flow clusters with $\beta = 0.142\pm0.007$ or $\Omega_M = 0.35\pm0.09$.Comment: 6 pages + 4 figures; accepted for publication in MNRA

Document generality: its computation for ranking

The increased variety of information makes it critical to retrieve documents which are not only relevant but also broad enough to cover as many different aspects of a certain topic as possible. The increased variety of users also makes it critical to retrieve documents that are jargon free and easy-to-understand rather than the specific technical materials. In this paper, we propose a new concept namely document generality computation. Generality of document is of fundamental importance to information retrieval. Document generality is the state or quality of docu- ment being general. We compute document general- ity based on a domain-ontology method that analyzes scope and semantic cohesion of concepts appeared in the text. For test purposes, our proposed approach is then applied to improving the performance of doc- ument ranking in bio-medical information retrieval. The retrieved documents are re-ranked by a combined score of similarity and the closeness of documents’ generality to that of a query. The experiments have shown that our method can work on a large scale bio-medical text corpus OHSUMED (Hersh, Buckley, Leone & Hickam 1994), which is a subset of MEDLINE collection containing of 348,566 medical journal references and 101 test queries, with an encouraging performance

Breakthrough Cancer Pain

Breakthrough cancer pain has attracted more and more attentions recently because it has become the biggest obstacle to control cancer pain. Pain can occur at any stage of cancer. Despite the aggressive treatment, some patients still experience high-intensity pain in the short term, which is commonly referred to as breakthrough pain. Typical breakthrough pain has clinical features such as rapid onset and short duration, and it has uncontrollable and unpredictable characteristics, which impact the overall life quality of patients and the therapeutic effect of cancer pain. It has always been a puzzle and difficult in clinical treatment of breakthrough cancer pain. This paper aims to provide a more detailed review of the definition, assessment tools, classification and characteristics, epidemiology, and mechanism and treatment of breakthrough cancer pain, in order to facilitate the future development of this work in clinical treatment
