A Milliped New to Michigan (Pselaphognatha: Polyxenus)

The authors wish to report the finding of representatives of the genus Polyxenus for the first time in Michigan (Fig. 1). In Bert M. Johnson\u27s survey (1954) of the millipedes of Michigan, no members of the subclass Pselaphognatha were reported. During the period of September through October 1970, the authors collected over 40 specimens of Polyxenus and observed over 100 in the field. All of the specimens were found in a mature pine stand in Ypsilanti Township

Brain Activation During Passive and Volitional Pedaling After Stroke

Background: Prior work indicates that pedaling-related brain activation is lower in people with stroke than in controls. We asked whether this observation could be explained by between-group differences in volitional motor commands and pedaling performance. Methods: Individuals with and without stroke performed passive and volitional pedaling while brain activation was recorded with functional magnetic resonance imaging. The passive condition eliminated motor commands to pedal and minimized between-group differences in pedaling performance. Volume, intensity, and laterality of brain activation were compared across conditions and groups. Results: There were no significant effects of condition and no Group × Condition interactions for any measure of brain activation. Only 53% of subjects could minimize muscle activity for passive pedaling. Conclusions: Altered motor commands and pedaling performance are unlikely to account for reduced pedaling-related brain activation poststroke. Instead, this phenomenon may be due to functional or structural brain changes. Passive pedaling can be difficult to achieve and may require inhibition of excitatory descending drive

Indigenous Healing in New Zealand: An Anthropological Analysis of Traditional and Modern Approaches to Well-Being

Drawing on contemporary anthropological approaches used by scholars of well-being and medical anthropology (i.e. Michael Jackson and Lisa Stevenson), I explore how indigenous healers in New Zealand blend “traditional” and “modern” elements to establish a creative and inclusive system. Specifically, I explore the use of herbal treatments, ritual chanting, and ceremonies that encapsulate Māori cultural values. I also explore the impact of biomedicine and New-Age wellness approaches on indigenous healing. I argue that Māori healing moves beyond the binary of “tradition” and “modern” as healers merge the past and present and combine the foreign and native. My research is based on published scholarly literature, participant observation I conducted during my semester abroad in Dunedin, New Zealand in Spring 2019, and semi-structured recorded interviews with tohunga (indigenous Māori healers). During my five-month stay, I spoke with tohunga, experienced indigenous ceremonies and karakia (ritual chanting) first-hand, and attended the Christchurch Healing Expo where I shadowed a Māori healer during a mirimiri (sacred ritual massage). My research demonstrates that it is impossible to fully separate Māori healing from other wellness systems because “indigenous” healing has always incorporated healing practices from other cultures. My honors thesis addresses the historical and cultural origins of Māori healing practices, how these practices integrate in contemporary society, as well as how the indigenous population perceives health. This research contributes to the anthropological study of wellness by reevaluating the meaning of “indigenous” healing and identity in contemporary New Zealand

The Experiences of Transgender and Gender Diverse Individuals Seeking Mental Health Treatment

Transgender and Gender Diverse (TGD) individuals are underserved in communities despite experiencing disproportionately higher rates of mental health distress. The cisheteronomativity of society creates chronic stressors that impact the mental health outcomes of TGD individuals. TGD individuals face the highest rates of discrimination in healthcare settings. Yet, little is known about the population\u27s specific experiences seeking mental health care. Using a phenomenological approach, this study interviewed eight TGD individuals to understand the experience of seeking mental health care. There were six themes: facilitation of seeking behaviors, barriers, type of care, characteristics of providers, identity disclosure, and burden of advocacy and education. Participants reported they look for providers who at the minimum are competent, respectful, and safe. Participants want providers willing to educate themselves on TGD identities and issues. In congruence with previous research, this study found that TGD individuals are experiencing significant discrimination while seeking mental health care. The current findings illuminate that there is a substantial gap in the education provided to counselors in training and training for those working in the field

Reliability and Validity of Ratings of Perceived Exertion in Persons With Multiple Sclerosis

Objective: To test the reliability and validity of using the Borg rating of perceived exertion (RPE) scale (ratings 6e20) in persons with multiple sclerosis (PwMS). Design: Nonrandomized repeated measures. Setting: Research laboratory. Participants: Volunteer sample (N=27) comprised of 16 PwMS (10 women) and 11 age-matched persons without multiple sclerosis (MS) (6 women). Clinical measures included symptomatic fatigue, depression, and MS functional capacity. Interventions: A submaximal cycling test was performed to estimate maximal capacity. Participants then pedaled for 2 minutes at 50% and 60% of predicted maximal oxygen consumption per unit time (V̇O2), and physiological measures and RPE were obtained (week 1: response protocol). One week later, participants replicated the prescribed V̇O2 using the RPE range from week 1 (week 2: reproduction protocol). V̇O2, heart rate, and respiratory quotient were measured continuously; RPE and workload were measured every minute; and blood lactate and mean arterial pressure were measured after exercise. Main Outcome Measures: RPE, workload, V̇O2, and heart rate from week 1 to week 2. Results: PwMS had greater fatigue (P2, and heart rate were similar between groups. Both groups had an intraclass correlation coefficient \u3e.86 for RPE, workload, and V̇O2. The intraclass correlation coefficient was comparatively lower for heart rate for both groups (MS group: .72, non-MS group: .83). RPE was highly correlated with V̇O2(rZ.691, P Conclusions: Results suggest that RPE can be reliably reproduced, is valid, and may be used in exercise prescription in mildly to moderately impaired PwMS during cycling exercise

The Effect of Topographic Factors on the Productivity of Mountain Grasslands in Northwestern Benin

The Atacora mountains range in northern Benin (660 m altitude) is a special ecosystem in the sudanian zone because of the overriding importance of topographic factors and shallow soils. The vegetation over this mountain range consists of shrub and tree savannas, woodlands and fallows. More and more cattle herds graze on this range. But the functioning of this ecosystem is still unknown like many others in the tropical zone (Sene & Zingari, 2001). This study aims to determine the impact of topography and mountain side exposure on the productivity of the Atacora mountains grasslands in the Atacora mountains

The First and the Last: A Confluence of Factors Leading to the Integration of Carver School of Missions and Social Work, 1955

The Carver School of Missions and Social Work, affiliated with the Southern Baptist Theological Seminary in Louisville, Kentucky, was an all-female social work program that eventually became the first seminary-affiliated social work program accredited by the Council on Social Work Education. This article examines Carver\u27s efforts towards racial integration during the late 1950s, which was a time of heightened racial tensions across the United States. This article is informed by a series of oral histories of the two African American women who integrated Carver in 1955

Instrument Bias Correction With Machine Learning Algorithms: Application to Field-Portable Mass Spectrometry

In situ sensors for environmental chemistry promise more thorough observations, which are necessary for high confidence predictions in earth systems science. However, these can be a challenge to interpret because the sensors are strongly influenced by temperature, humidity, pressure, or other secondary environmental conditions that are not of direct interest. We present a comparison of two statistical learning methods—a generalized additive model and a long short-term memory neural network model for bias correction of in situ sensor data. We discuss their performance and tradeoffs when the two bias correction methods are applied to data from submersible and shipboard mass spectrometers. Both instruments measure the most abundant gases dissolved in water and can be used to reconstruct biochemical metabolisms, including those that regulate atmospheric carbon dioxide. Both models demonstrate a high degree of skill at correcting for instrument bias using correlated environmental measurements; the difference in their respective performance is less than 1% in terms of root mean squared error. Overall, the long short-term memory bias correction produced an error of 5% for O2 and 8.5% for CO2 when compared against independent membrane DO and laser spectrometer instruments. This represents a predictive accuracy of 92–95% for both gases. It is apparent that the most important factor in a skillful bias correction is the measurement of the secondary environmental conditions that are likely to correlate with the instrument bias. These statistical learning methods are extremely flexible and permit the inclusion of nearly an infinite number of correlates in finding the best bias correction solution

Numerical investigation of the Arctic ice–ocean boundary layer and implications for air–sea gas fluxes

The definitive version was published in Ocean Science 13 (2017): 61-75, doi:10.5194/os-13-61-2017.In ice-covered regions it is challenging to determine constituent budgets – for heat and momentum, but also for biologically and climatically active gases like carbon dioxide and methane. The harsh environment and relative data scarcity make it difficult to characterize even the physical properties of the ocean surface. Here, we sought to evaluate if numerical model output helps us to better estimate the physical forcing that drives the air–sea gas exchange rate (k) in sea ice zones. We used the budget of radioactive 222Rn in the mixed layer to illustrate the effect that sea ice forcing has on gas budgets and air–sea gas exchange. Appropriate constraint of the 222Rn budget requires estimates of sea ice velocity, concentration, mixed-layer depth, and water velocities, as well as their evolution in time and space along the Lagrangian drift track of a mixed-layer water parcel. We used 36, 9 and 2 km horizontal resolution of regional Massachusetts Institute of Technology general circulation model (MITgcm) configuration with fine vertical spacing to evaluate the capability of the model to reproduce these parameters. We then compared the model results to existing field data including satellite, moorings and ice-tethered profilers. We found that mode sea ice coverage agrees with satellite-derived observation 88 to 98 % of the time when averaged over the Beaufort Gyre, and model sea ice speeds have 82 % correlation with observations. The model demonstrated the capacity to capture the broad trends in the mixed layer, although with a significant bias. Model water velocities showed only 29 % correlation with point-wise in situ data. This correlation remained low in all three model resolution simulations and we argued that is largely due to the quality of the input atmospheric forcing. Overall, we found that even the coarse-resolution model can make a modest contribution to gas exchange parameterization, by resolving the time variation of parameters that drive the 222Rn budget, including rate of mixed-layer change and sea ice forcings.Funding for this research was provided by the NSF Arctic Natural Sciences program through Award # 1203558

Mid-infrared signatures of hydroxyl containing water clusters: Infrared laser Stark spectroscopy of OH–H2O and OH(D2O)n (n = 1-3)

Small water clusters containing a single hydroxyl radical are synthesized in liquid helium droplets. The OH–H2O and OH(D2O)n clusters (n = 1-3) are probed with infrared laser spectroscopy in the vicinity of the hydroxyl radical OH stretch vibration. Experimental band origins are qualitatively consistent with ab initio calculations of the global minimum structures; however, frequency shifts from isolated OH are significantly over-predicted by both B3LYP and MP2 methods. An effective Hamiltonian that accounts for partial quenching of electronic angular momentum is used to analyze Stark spectra of the OH–H2O and OH–D2O binary complexes, revealing a 3.70(5) D permanent electric dipole moment. Computations of the dipole moment are in good agreement with experiment when large-amplitude vibrational averaging is taken into account. Polarization spectroscopy is employed to characterize two vibrational bands assigned to OH(D2O)2, revealing two nearly isoenergetic cyclic isomers that differ in the orientation of the non-hydrogen-bonded deuterium atoms relative to the plane of the three oxygen atoms. The dipole moments for these clusters are determined to be approximately 2.5 and 1.8 D for “up-up” and “up-down” structures, respectively. Hydroxyl stretching bands of larger clusters containing three or more D2O molecules are observed shifted approximately 300 cm−1 to the red of the isolated OH radical. Pressure dependence studies and ab initio calculations imply the presence of multiple cyclic isomers of OH(D2O)3.Fil: Hernández, Federico Javier.
