Levels of depression in transgender people and its predictors: results of a large matched control study with transgender people accessing clinical services

Background: Depression is a serious disorder which significantly impacts wellbeing and quality of life. Studies exploring mental wellbeing in the transgender population are mostly limited by small, non-homogenous samples and lack of matched controls. This study aimed to address these limitations and explore depression rates in a large sample of transgender people, compared with matched controls from the general population, as well as factors predicting depression in those taking cross-sex hormone treatment (CHT) compared to those not. Methods: Transgender individuals (n=913) completed a measure of depression, measures which predict psychopathology (self-esteem, victimization, social support, interpersonal problems), and information regarding CHT use. Participants were matched by age and experienced gender with adults from the general population who had completed the measure of depression. Results: Individuals were categorized as having no, possible or probable depressive disorder. Transgender individuals not on CHT had a nearly four-fold increased risk of probable depressive disorder, compared to controls. Older age, lower self-esteem, poorer interpersonal function and less social support predicted depressive disorder. Use of CHT was associated with less depression. Limitations: Participants were attending a national gender identity service and therefore represent only a sub-group of transgender people. Due to the cross-sectional design, longitudinal research is required to fully confirm the finding that CHT use reduces depression. Conclusion: This study confirms that non-treated transgender individuals have an increased risk of a depressive disorder. Interventions offered alongside gender affirming treatment to develop interpersonal skills, increase self-esteem and improve social support may reduce depression and prepare individuals for a more successful transition

Structural Design for a Neptune Aerocapture Mission

A multi-center study was conducted in 2003 to assess the feasibility of and technology requirements for using aerocapture to insert a scientific platform into orbit around Neptune. The aerocapture technique offers a potential method of greatly reducing orbiter mass and thus total spacecraft launch mass by minimizing the required propulsion system mass. This study involved the collaborative efforts of personnel from Langley Research Center (LaRC), Johnson Space Flight Center (JSFC), Marshall Space Flight Center (MSFC), Ames Research Center (ARC), and the Jet Propulsion Laboratory (JPL). One aspect of this effort was the structural design of the full spacecraft configuration, including the ellipsled aerocapture orbiter and the in-space solar electric propulsion (SEP) module/cruise stage. This paper will discuss the functional and structural requirements for each of these components, some of the design trades leading to the final configuration, the loading environments, and the analysis methods used to ensure structural integrity. It will also highlight the design and structural challenges faced while trying to integrate all the mission requirements. Component sizes, materials, construction methods and analytical results, including masses and natural frequencies, will be presented, showing the feasibility of the resulting design for use in a Neptune aerocapture mission. Lastly, results of a post-study structural mass optimization effort on the ellipsled will be discussed, showing potential mass savings and their influence on structural strength and stiffnes

Conservatism Between Theory and Practice: The Case of Migration to Europe

This paper explores the neglected relationship between conservatism as a political theory, and conservatism as political practice, using the example of recent immigration to Europe. A cursory glance at how European politicians have responded to migration challenges suggests that they roughly divide into a leftist ‘liberal’ and a rightist ‘conservative’ camp, between those that favour some form of an open-arms policy and those who prefer to close borders. The situation, however, is more complex. This article engages with the resources of conservative theory to argue that there are many distinct conservative-theoretical positions for any one policy point. Using contemporary migration patterns as a case-study, we suggest that Conservative parties have not borrowed much from conservative theory in its variety of incarnations. In fact, conservative theory can buttress a course of action that is generous toward migrants and at odds with the claims of right-wing populist movements. While certain strands of conservatism imagine a homogenous people, there are others that are no less propluralization than liberal theory, and sometimes more so
