Disclosure in lesbian, gay and bisexual cancer care: towards a salutogenic healthcare environment

open access articleBackground: The literature on sexual orientation disclosure is arguably one of the most developed in the field of lesbian, gay and bisexual (LGB) people in healthcare in English speaking countries however, relatively little research has been conducted into disclosure in cancer care. Studies have been mainly undertaken in primary care where distinct circumstances pertain and where the benefits of disclosure include obtaining appropriate health information, treatment advice and avoiding misdiagnosis. Methods: We conducted an in-depth qualitative study primarily recruiting patients through oncology care in hospital settings and through LGB community cancer support groups. Data were gathered through semi-structured interviews with 30 LGB patients with different cancer types. Results: Data were analysed using thematic analysis and interpreted and interrogated through salutogenesis theory which offers a useful lens through which to consider the health promoting effects of sexual orientation disclosure in cancer care. We present three themes as part of the analysis: Authenticity as a driver for disclosure in cancer care, Partners as a (potential) salutogenic resource and Creating safe, healing environments conducive to disclosure. The findings are reported and discussed in relation to three inter-related concepts from current salutogenesis theorising including a sense of coherence, generalised resistance resources and healing environments which can facilitate sexual orientation disclosure. Conclusion: Our findings enable a more nuanced approach to understanding disclosure in this context. This study contributes to the literature through its articulation of the salutogenic potential of disclosure (if responded to appropriately) for LGB patients as individuals, in relationship to their partners or carers and the role of creating a visible healing-oriented optimal environment to promote quality of life and recovery

PEDAGOGY OF PITCH IN L2 BLACKFOOT

Pitch in Blackfoot is characterized by the raising of relative pitch on a syllable in a word. Pitch is not a consciously recognized piece of information among native speakers or teachers. However, pitch is important as it impacts the meaning of words. This study looks at the efficacy of visual guides for Blackfoot pronunciation of pitch by second language learners. I hypothesized that use of visual assistance would improve pitch pronunciation in second language learners. Subjects were nine Blackfoot learners recruited on campus. Participants were shown 15 words with images and asked to pronounce them. Subjects were then given pitch art, a visual tool mapping pitch, and asked to pronounce the words again with the visual aid. The recordings were analyzed in a phonetic program called Praat, and the measurements were inputted and organized in an excel file for further analysis. Their pronunciation was compared to that of a native speaker. One participants results were deemed unusable due to creaky voice. Results showed four of the remaining eight learners improved pronunciation overall, but the remaining participants did not. Three conclusions were drawn from these results: (i) the immediate use of images without instruction does not significantly improve pronunciation, (ii) complexity and familiarity of words impact second language pronunciation, and (iii) when words are simple and/or familiar, learners perform better with pitch, and when words are complex or unfamiliar learners struggle with pitch. This study contributes to the field of second language acquisition, especially regarding Blackfoot and other languages with pitch. In addition, language in the Blackfeet community plays a significant role in identity and pride, and, as such, speakers desire to sound authentic and as “native-like” as possible. This study hopes to improve education of Blackfoot language and help learners’ pronouncing Blackfoot words

Lithium abundances in nearby FGK dwarf and subgiant stars: internal destruction, Galactic chemical evolution, and exoplanets

We derive atmospheric parameters and lithium abundances for 671 stars and include our measurements in a literature compilation of 1381 dwarf and subgiant stars. First, a "lithium desert" in the effective temperature (Teff) versus lithium abundance (A_Li) plane is observed such that no stars with Teff~6075 K and A_Li~1.8 are found. We speculate that most of the stars on the low A_Li side of the desert have experienced a short-lived period of severe surface lithium destruction as main-sequence or subgiant stars. Next, we search for differences in the lithium content of thin-disk and thick-disk stars, but we find that internal processes have erased from the stellar photospheres their possibly different histories of lithium enrichment. Nevertheless, we note that the maximum lithium abundance of thick-disk stars is nearly constant from [Fe/H]=-1.0 to -0.1, at a value that is similar to that measured in very metal-poor halo stars (A_Li~2.2). Finally, differences in the lithium abundance distribution of known planet-host stars relative to otherwise ordinary stars appear when restricting the samples to narrow ranges of Teff or mass, but they are fully explained by age and metallicity biases. We confirm the lack of a connection between low lithium abundance and planets. However, we find that no low A_Li planet-hosts are found in the desert Teff window. Provided that subtle sample biases are not responsible for this observation, this suggests that the presence of gas giant planets inhibit the mechanism responsible for the lithium desert.Comment: ApJ, in press.

Succession of bacterial and fungal communities within biofilms of a chlorinated drinking water distribution system

Understanding the temporal dynamics of multi-species biofilms in Drinking Water Distribution Systems (DWDS) is essential to ensure safe, high quality water reaches consumers after it passes through these high surface area reactors. This research studied the succession characteristics of fungal and bacterial communities un der controlled environmental conditions fully representative of operational DWDS. Microbial communities were observed to increase in complexity after one month of biofilm development but they did not reach stability after three months. Changes in cell numbers were faster at the start of biofilm formation and tended to decrease over time, despite the continuing changes in bacterial community composition. Fungal diversity was markedly less than bacterial diversity and had a lag in responding to temporal dynamics. A core-mixed community of bacteria including Pseudomonas, Massillia and Sphingomonas and the fungi Acremonium and Neocosmopora were present constantly and consistently in the biofilms over time and conditions studied. Monitoring and managing biofilms and such ubiquitous core microbial communities are key control strategies to ensuring the delivery of safe drinking water via the current ageing DWDS infrastructure

Algorithmic Collusion by Large Language Models

The rise of algorithmic pricing raises concerns of algorithmic collusion. We conduct experiments with algorithmic pricing agents based on Large Language Models (LLMs), and specifically GPT-4. We find that (1) LLM-based agents are adept at pricing tasks, (2) LLM-based pricing agents autonomously collude in oligopoly settings to the detriment of consumers, and (3) variation in seemingly innocuous phrases in LLM instructions ("prompts") may increase collusion. These results extend to auction settings. Our findings underscore the need for antitrust regulation regarding algorithmic pricing, and uncover regulatory challenges unique to LLM-based pricing agents

Noether's second theorem in a general setting. Reducible gauge theories

We prove Noether's direct and inverse second theorems for Lagrangian systems on fiber bundles in the case of gauge symmetries depending on derivatives of dynamic variables of an arbitrary order. The appropriate notions of reducible gauge symmetries and Noether's identities are formulated, and their equivalence by means of certain intertwining operator is proved.Comment: 20 pages, to be published in J.

Teaching Excellence: A Reaction to the Smith Commission Report and its Effects

This paper has been written partially in response to the Smith Commission Report, and partially in response to the reactions the report has elicited already. The Smith Commission Report voiced many valid concerns about teaching excellence; however, many of the so-called "innovations" that have been developed in answer to Stuart Smith's call for teaching excellence are, in fact, little different from those techniques implemented under the auspices of the Ontario Universities Program for Institutional Development (OUPID) in the 1960's and early 1970's. This being the case, the authors feel that the most likely result will be a similar lack of success. It is, therefore, our suggestion that an attempt ought to be made to change the infrastructure of the university sys- tem so that it supports good teaching and research with equal measure. This, above all else, should lead to real improvements in the quality of teaching

Understanding variation in men’s help-seeking for cancer symptoms: a semi-structured interview study

Men appear more likely to delay seeking medical advice for cancer symptoms, resulting in later stage at diagnosis and poorer health outcomes. Limited research has investigated variation in men’s experiences of and responses to cancer symptoms. This study examined the psychosocial aspects of men’s help-seeking for cancer symptoms, as well as potential variation across men residing in urban and rural Australia. Semi-structured interviews were conducted with men recently diagnosed with cancer (n=13). Participants’ partners (n=8) were recruited to enable data triangulation. Interview schedules addressed participants’ pathway to cancer treatment, cancer knowledge, masculinity, and rural living. A theoretical thematic analysis approach was used. Medical help-seeking behaviour was similar for participants residing in urban and rural areas. Five key themes and one sub-theme were identified, including: symptom factors, traditional masculine norms (sub-theme: women’s health-related responsibilities), level of concern, conflicting responsibilities and access, and trust in medical professionals. Participants from rural Australia experienced greater access difficulties and noted optimism regarding symptoms. Results highlight important within-gender differences in the psychosocial barriers to help-seeking for cancer symptoms. Future research should further explore variation between men and test the predictive strength of factors

Interpretation and the Constraints on International Courts

This paper argues that methodologies of interpretation do not do what they promise – they do not constrain interpretation by providing neutral steps that one can follow in finding out a meaning of a text – but nevertheless do their constraining work by being part of what can be described as the legal practice
