Constituting American Masculinity

"Constituting American Masculinity" analyzes the tensions among competing discourses on modes of manhood during the Constitutional period that lay the ground for the move toward political independence. In particular, the essay takes up the debate over the Constitution to demonstrate how it reframes manhood, deploying insecurity as its engine to catch the confederated states in a masculine double bind. This double bind enlists male citizens into a mandatory political dependency that they can only name independence. The Constitutional moment thus becomes, among other things, a mechanism of democratic imposture that promises equalitarian social and political relations, but that, in a kind of leger-de-main, works to install a hierarchical relation in the name of democracy

Sport Discontinuation: An Assessment of Goal Achievement via Empirical Measures

Collegiate athletic teams are being eliminated at an alarming rate; however, empirical research of athletic spending and participation after these cuts occur is lacking. This study compared whether the proffered rationales for discontinuing teams were consistent with the measurable budgetary and participation outcomes. From a sample of NCAA Division I institutions that discontinued at least one team between the academic years 2000-01 and 2008-09 (N = 125), a total of 49 schools with documented cut rationales were identified. The EADA cutting tool was then used to examine athletic revenues, expenses, and participation numbers from the year prior and the year after the cuts to determine, via descriptive statistics and paired t-tests, if the stated objectives were met. The three reasons primarily cited for the program elimination included: reducing athletic spending (44.9%), reallocating resources (42.9%), and Title IX compliance (18.4%). Statistical analysis revealed that only institutions citing reallocation of athletic resources were able to achieve their stated goals. Institutions citing efforts to reduce athletic spending had significant increases in athletic expenses and none of the institutions citing Title IX compliance achieved substantial proportionality. These results show a troubling disconnection between the elimination rationale and the budgetary and participation outcomes that is worthy of additional investigation

Wideband propagation measurement system using spread spectrum signaling and TDRS

In this paper, a wideband propagation measurement system, which consisted of a ground-based transmitter, a mobile receiver, and a data acquisition system, was constructed. This system has been employed in a study of the characteristics of different propagation environments, such as urban, suburban and rural areas, by using a pseudonoise spreading sequence transmitted over NASA's Tracking and Data Relay Satellite System. The hardware and software tests showed that it met overall system requirements and it was very robust during a 3-month-long outdoor data collection experiment

Channel fading for mobile satellite communications using spread spectrum signaling and TDRSS

This paper will present some preliminary results from a propagation experiment which employed NASA's TDRSS and an 8 MHz chip rate spread spectrum signal. Channel fade statistics were measured and analyzed in 21 representative geographical locations covering urban/suburban, open plain, and forested areas. Cumulative distribution Functions (CDF's) of 12 individual locations are presented and classified based on location. Representative CDF's from each of these three types of terrain are summarized. These results are discussed, and the fade depths exceeded 10 percent of the time in three types of environments are tabulated. The spread spectrum fade statistics for tree-lined roads are compared with the Empirical Roadside Shadowing Model

Advanced S-Band studies using the TDRSS communications satellite

This report will describe the design, implementation, and results of a propagation experiment which used TDRSS to transmit spread signals at S-Band to an instrumented mobile receiver. The results consist of fade measurements and distribution functions in 21 environments across the Continental United States (CONUS). From these distribution functions, some idea may be gained about what system designers should expect for excess path loss in many mobile environments. Some of these results may be compared against similar measurements made with narrowband beacon measurements. Such comparisons provide insight into what gains the spread signaling system may or may not have in multipath and shadowing environments

Articular cartilage surface roughness as an imaging‐based morphological indicator of osteoarthritis: A preliminary investigation of osteoarthritis initiative subjects

Current imaging‐based morphometric indicators of osteoarthritis (OA) using whole‐compartment mean cartilage thickness (MCT) and volume changes can be insensitive to mild degenerative changes of articular cartilage (AC) due to areas of adjacent thickening and thinning. The purpose of this preliminary study was to evaluate cartilage thickness‐based surface roughness as a morphometric indicator of OA. 3D magnetic resonance imaging (MRI) datasets were collected from osteoarthritis initiative (OAI) subjects with Kellgren–Lawrence (KL) OA grades of 0, 2, and 4 (n = 10/group). Femoral and tibial AC volumes were converted to two‐dimensional thickness maps, and MCT, arithmetic surface roughness (Sa), and anatomically normalized Sa (normSa) were calculated. Thickness maps enabled visualization of degenerative changes with increasing KL grade, including adjacent thinning and thickening on the femoral condyles. No significant differences were observed in MCT between KL grades. Sa was significantly higher in KL4 compared to KL0 and KL2 in the whole femur (KL0: 0.55 ± 0.10 mm, KL2: 0.53 ± 0.09 mm, KL4: 0.79 ± 0.18 mm), medial femoral condyle (KL0: 0.42 ± 0.07 mm, KL2: 0.48 ± 0.07 mm, KL4: 0.76 ± 0.22 mm), and medial tibial plateau (KL0: 0.42 ± 0.07 mm, KL2: 0.43 ± 0.09 mm, KL4: 0.68 ± 0.27 mm). normSa was significantly higher in KL4 compared to KL0 and KL2 in the whole femur (KL0: 0.22 ± 0.02, KL2: 0.22 ± 0.02, KL4: 0.30 ± 0.03), medial condyle (KL0: 0.17 ± 0.02, KL2: 0.20 ± 0.03, KL4: 0.29 ± 0.06), whole tibia (KL0: 0.34 ± 0.04, KL2: 0.33 ± 0.05, KL4: 0.48 ± 0.11) and medial plateau (KL0: 0.23 ± 0.03, KL2: 0.24 ± 0.04, KL4: 0.40 ± 0.10), and significantly higher in KL2 compared to KL0 in the medial femoral condyle. Surface roughness metrics were sensitive to degenerative morphologic changes, and may be useful in OA characterization and early diagnosis. © 2017 Orthopaedic Research Society. Published by Wiley Periodicals, Inc. J Orthop Res 35:2755–2764, 2017.A custom algorithm was used to create two‐dimensional articular cartilage thickness maps of patients from the Osteoarthritis Initiative. Thickness maps demonstrate significantly increased surface roughness as a function of increasing Kellgren–Lawrence (KL) osteoarthritis (OA) grade, particularly in the medial femoral condyle, though mean cartilage thickness was not found to differ significantly between KL grades. Surface roughness‐based metrics have potential utility as morphological indicators of OA.Peer Reviewedhttps://deepblue.lib.umich.edu/bitstream/2027.42/141486/1/jor23588_am.pdfhttps://deepblue.lib.umich.edu/bitstream/2027.42/141486/2/jor23588.pd

'I don't want anyone to know': Experiences of obtaining access to HIV testing by Eastern European, non-European Union sex workers in Amsterdam, the Netherlands.

Historically, the Netherlands has hosted a large number of migrant sex workers. Since sex work is considered a legal profession it might serve as an example of better access to health services, including HIV testing, at least for those working within the legal framework. However, migrant sex workers, especially non-European Union (EU) nationals, might not be eligible to register for official employment and thus face obstacles in obtaining access to health services, becoming essentially invisible. This study examined context-specific vulnerabilities of migrant female sex workers (FSWs) from Belarus, Moldova, Russia and Ukraine, whether and how they have access to HIV testing compared to other EE, non-EU migrant FSWs in Amsterdam in the Netherlands. We conducted a multi-stakeholder perspective study from November 2015 to September 2017 in Amsterdam. The study comprised 1) semi-structured interviews with key stakeholders (N = 19); 2) in-depth interviews with Eastern European, non-EU migrant FSWs (N = 5) and field observations of the escort agency working with them; and 3) in-depth interviews with key stakeholders (N = 12). We found six key barriers to HIV testing: 1) migration and sex-work policies; 2) stigma, including self-stigmatization; 3) lack of trust in healthcare providers or social workers; 4) low levels of Dutch or English languages; 5) negative experience in accessing healthcare services in the home country; and 6) low perceived risk and HIV-related knowledge. Having a family and children, social support and working at the licensed sex-work venues might facilitate HIV testing. However, Internet-based sex workers remain invisible in the sex-work industry. Our findings indicate the importance of addressing women's diverse experiences, shaped by intrapersonal, interpersonal, community, network and policy-level factors, with stigma being at the core. We call for the scaling up of outreach interventions focusing on FSWs and, in particular, migrant FSWs working onlin

Unfrustrated Qudit Chains and their Ground States

We investigate chains of 'd' dimensional quantum spins (qudits) on a line with generic nearest neighbor interactions without translational invariance. We find the conditions under which these systems are not frustrated, i.e. when the ground states are also the common ground states of all the local terms in the Hamiltonians. The states of a quantum spin chain are naturally represented in the Matrix Product States (MPS) framework. Using imaginary time evolution in the MPS ansatz, we numerically investigate the range of parameters in which we expect the ground states to be highly entangled and find them hard to approximate using our MPS method.Comment: 5 pages, 5 figures.

'Virus Carriers' and HIV testing: navigating Ukraine's HIV policies and programming for female sex workers

Background: There are an estimated 80,100 female sex workers (FSWs) in Ukraine, of whom 7% are living with HIV. Early HIV diagnosis continues to be a public health priority in Ukraine as only approximately 54% of people living with HIV are diagnosed nationwide. This study aims to analyse the content, context and discourse of HIV testing policies among female sex workers in Ukraine and how these policies are understood and implemented in practice. Methods: To analyse past and current national policies, we searched the database of the Ukrainian Parliament and the Ministry of Health for relevant policy documents (e.g. legislation and orders). To analyse the day-to-day practice of those involved in the implementation of these HIV programmes, we conducted face-to-face semi-structured interviews with key stakeholders. All data were coded using deductive thematic analysis initially guided by the Policy Triangle, a framework which addresses policy content, the process of policy-making, the health policy context, actors involved in policy formulation and implementation. Results: HIV testing policies are formed and implemented in the post-Soviet context through a vertical system of AIDS clinics, resulting in the separation of key affected populations from the rest of the health system. Successive testing policies have been strongly influenced by international donors and non-governmental organisations. Furthermore, a lack of government funding for HIV prevention created a gap that international donors and local non-governmental organisations covered to ensure the implementation of testing policies. Their role, however, had limited influence on the Ukrainian government to increase funding for prevention, including testing of FSWs. Since the early 1990s, when stigmatising and discriminatory forced/mandatory HIV testing was applied, these approaches were slowly replaced with voluntary testing, self-testing and assisted HIV testing, yet stigma was found to be a barrier among FSWs to access testing. Conclusion: Poor governance and the fragmentation of the health system, ongoing health sector reforms, shrinking international funding, and persisting stigma towards people living with HIV and sex workers might impede the continuity and sustainability of HIV testing programmes. Local civil society may now have the opportunity to contribute to the development and further implementation of HIV testing policies in Ukraine

Proton- and ammonium-sensing by histaminergic neurons controlling wakefulness

The histaminergic neurons in the tuberomamillary nucleus (TMN) of the posterior hypothalamus are involved in the control of arousal. These neurons are sensitive to hypercapnia as has been shown in experiments examining c-Fos expression, a marker for increased neuronal activity. We investigated the mechanisms through which TMN neurons respond to changes in extracellular levels of acid/CO2. Recordings in rat brain slices revealed that acidification within the physiological range (pH from 7.4 to 7.0), as well as ammonium chloride (5 mM), excite histaminergic neurons. This excitation is significantly reduced by antagonists of type I metabotropic glutamate receptors and abolished by benzamil, an antagonist of acid-sensing ion channels (ASICs) and Na+/Ca2+ exchanger, or by ouabain which blocks Na+/K+ ATPase. We detected variable combinations of 4 known types of ASICs in single TMN neurons, and observed activation of ASICs in single dissociated TMN neurons only at pH lower than 7.0. Thus, glutamate, which is known to be released by glial cells and orexinergic neurons, amplifies the acid/CO2-induced activation of TMN neurons. This amplification demands the coordinated function of metabotropic glutamate receptors, Na+/Ca2+ exchanger and Na+/K+ ATPase. We also developed a novel HDC-Cre transgenic reporter mouse line in which histaminergic TMN neurons can be visualized. In contrast to the rat, the mouse histaminergic neurons lacked the pH 7.0-induced excitation and displayed only a minimal response to the mGluR I agonist DHPG (0.5 μM). On the other hand, ammonium-induced excitation was similar in mouse and rat. These results are relevant for the understanding of the neuronal mechanisms controlling acid/CO2-induced arousal in hepatic encephalopathy and obstructive sleep apnoea. Moreover, the new HDC-Cre mouse model will be a useful tool for studying the physiological and pathophysiological roles of the histaminergic system
