Publications and Research

Background

People belonging to sexual minority groups have higher levels of suicidality than heterosexuals. However, findings regarding suicide death are sparse. Using unique national data from two countries, we investigated whether individuals entering a same-sex marriage (SSM), a proxy group of sexual minority individuals, had higher suicide rates than those entering opposite-sex marriage (OSM).

Methods

A cohort study of all males and females who entered an SSM (n=28 649) or OSM (n=3 918 617) in Denmark and Sweden during 1989–2016 was conducted. Incidence rate ratios (IRRs) for suicide were calculated using adjusted Poisson regression models.

Results

In total, 97 suicides …

Sensitivity Comparison Of Open-Circuit Airgap Flux Between Surface-Mounted Permanent Magnet And Spoke-Type Permanent Magnet Machines Considering Manufacturing Tolerances, Cha-Seung Jun, Ohbong Kwon, Byung-Il Kwon

Publications and Research

The study compares the sensitivities of open-circuit airgap flux (OCAF) between a surface-mounted permanent magnet (SPM) machine and a spoke-type PM machine based on variations in airgap length including additional airgaps between permanent magnets and rotor core and between segmented stator cores to achieve high quality electric machines. Analytical equations deduced from magnetic equivalent circuits (MECs) are used to directly compare natural-born characteristics of the OCAF of the two machines. First, the MEC of each machine is modeled by considering two additional airgaps between the PMs and rotor core and between the segmented stator cores. Second, the OCAF equation of …

Scythes, Sickles And Other Blades: Defining The Diversity Of Pectoral Fin Morphotypes In Pachycormiformes, Jeff J. Liston, Anthony E. Maltese, Paul H. Lambers, Dominique Delsate, William E.H. Harcourt-Smith, Anneke H. Van Heteren

Publications and Research

The traditional terminology of ‘scythe’ or ‘sickle’ shaped is observed to be flawed as an effective descriptor for pectoral fin shape in pachycormids. The diversity of pachycormid pectoral fin shapes is assessed across the 14 recognised genera that preserve complete pectoral fins, and improved terms are defined to more effectively describe their form, supported by anatomical observation and aspect ratio analysis of individual fins, and corroborated by landmark analysis. Three clear and distinct pectoral fin structural morphotypes emerge (falceform, gladiform, falcataform), reflecting a diversity of pachycormid lifestyles throughout the Mesozoic, from agile pursuit predator to slow-cruising suspension feeder.

Publications and Research

The origins of spin lifetimes in quantum systems is a matter of importance in several areas of quantum information. Spectrally mapping spin relaxation processes provides insight into their origin and motivates methods to mitigate them. In this paper, we map nuclear relaxation in a prototypical system of ¹³C nuclei in diamond coupled to Nitrogen Vacancy (NV) centers over a wide field range (1 mT-7 T). Nuclear hyperpolarization through optically pumped NV electrons allows signal measurement savings exceeding million-fold over conventional methods. Through a systematic study with varying substitutional electron (P1 center) and ¹³C concentrations, we identify the operational …

Public Health Research Priorities To Address Female Genital Mutilation Or Cutting In The United States, Holly G. Atkinson, Deborah Ottenheimer, Ranit Mishori

Publications and Research

Female genital mutilation or cut- ting (FGM/C), an age-old tradition that is still widely practiced around the world, is gaining recognition as an important public health issue in the United States. Increasingly, because of migration, women and girls affected by FGM/C have become members of host communities where the practice is not culturally acceptable.

According to recent conservative estimates, more than 513 000 immigrant women and girls living in the United States have undergone or are at risk for FGM/C, a significant increase from the 1990 estimate of 168 000. The arrests of physicians in Michigan in 2017 for performing …

“We Cannot Imagine”: Us Preservice Teachers’ Othering Of Trans And Gender Creative Student Experiences, Elizabeth E. Blair, Sherry L. Deckman

Publications and Research

Research suggests that teachers are not meeting the needs of trans and gender creative students. Thus, we ask: How do US preservice teachers (PSTs) discursively construct the experiences of trans and gender creative students? How are these constructions informed by and reinscribe broader gender normativities in educational contexts? We analyzed 549 PST authored, online discussion posts from an educational foundations course, finding PSTs lacked familiarity with and engaged in rhetorical distancing from trans and gender creative student experiences suggesting barriers to empathy that may obstruct teacher-student relationships and promotion of equity, which teacher education is called to address.

Beyond Europeanization: The Politics Of Scale And Positionality In Lithuania’S Alternative Food Networks, Renata Blumberg, Diana Mincyte

Publications and Research

This article brings geographical insights to understanding the Europeanization of agri-food politics in new European Union member states. Most literature on agri-food policy and law in the European Union has conceptualized policy making and implementation as an institutional process involving multiple levels of governance. In this perspective, Europeanization is understood as a process through which stakeholders formulate, negotiate, and implement legal principles and procedures across various institutions at different levels of governance. By employing the conceptual tools developed in geographical research, we contribute a spatial and historical dimension to these studies. Our analysis shows how the politics of scale and …

Publications and Research

Pakistan is among the top ten countries adversely affected by climate change. More specifically, there is concern that climate change may cause longer and severer spells of droughts. To quantify the change in the characteristics of droughts in Pakistan over the years, we have evaluated spatio-temporal trends of droughts in Pakistan over the period 1902–2015 using Standardized Precipitation Evapotranspiration Index (SPEI). Additionally, the Spatial “K” luster Analysis using Tree Edge Removal (SKATER) method was employed to regionalize droughts into five contiguous zones. The run theory was then applied to each zone to identify drought events and characterize them in terms …

The Concurrent Decline Of Soil Lead And Children’S Blood Lead In New Orleans, Howard W. Mielke, Christopher R. Gonzales, Eric T. Powell, Mark A. S. Laidlow, Kenneth J. Berry, Paul W. Mielke Jr., Sara Perl Egendorf

Publications and Research

Lead (Pb) is extremely toxic and a major cause of chronic diseases worldwide. Pb is associated with health disparities, particularly within low-income populations. In biological systems, Pb mimics calcium and, among other effects, interrupts cell signaling. Furthermore, Pb exposure results in epigenetic changes that affect multigenerational gene expression. Exposure to Pb has decreased through primary prevention, including removal of Pb solder from canned food, regulating lead-based paint, and especially eliminating Pb additives in gasoline. While researchers observe a continuous decline in children’s blood lead (BPb), reservoirs of exposure persist in topsoil, which stores the legacy dust from leaded gasoline and …

Venom Diversity And Evolution In The Most Divergent Cone Snail Genus Profundiconus, Guilia Fassio, Maria Vittoria Modica, Lou Mary, Paul Zaharias, Alexander E. Fedosov, Juliette Gorson, Yuri I. Kantor, Mandë E. Holford, Nicolas Puillandre

Publications and Research

Profundiconus is the most divergent cone snail genus and its unique phylogenetic position, sister to the rest of the family Conidae, makes it a key taxon for examining venom evolution and diversity. Venom gland and foot transcriptomes of Profundiconus cf. vaubani and Profundiconus neocaledonicus were de novo assembled, annotated, and analyzed for differential expression. One hundred and thirty-seven venom components were identified from P. cf. vaubani and 82 from P. neocaledonicus, with only four shared by both species. The majority of the transcript diversity was composed of putative peptides, including conotoxins, profunditoxins, turripeptides, insulin, and prohormone-4. However, there were also …

Racial And Ethnic Disparities In Palliative Care: A Systematic Scoping Review, Daniel Gardner, Meredith Doherty, Gleneara Bates, Aliza Koplow, Sarah C. Johnson

Publications and Research

Despite the advances and spread of palliative care programs, communities of color remain significantly underserved. Although these disparities are widely known, there is a marked lack of empirical evidence. The authors conducted a systematic scoping review that synthesized the literature since 2000 about racial and ethnic disparities in palliative and end-of-life care. We searched PubMed, Medline, SocIndex, CINAHL, Social Work Abstracts, and PsycINFO, using search terms including palliative care or end-of-life care, disparities or barriers or utilization, and race or ethnicity or African American or Hispanic. Findings lend support to extant literature that social environmental barriers and disparities distinctly affect …

Innovative Collaborations: Social Work Student Interns At Public Libraries, Sarah C. Johnson

Publications and Research

While the collaborative trend among professional social workers and librarians is garnering much-deserved attention, literature about social work students partnering with public libraries is virtually non-existent. In fact, there are at least 73 partnerships yet a scarcity of academic literature addresses social work interns within public libraries. While there are students at Canadian libraries, this research focuses on the bulk of known partnerships based in the United States. Emerging from a mix of interviews and public resources, the author’s inquiry fosters this call to action: Social work educators must initiate interagency collaboration with libraries in order for students to expand …

Mean Propulsive Velocity Is A Viable Method For Adjusting The Resistance-Training Load At Moderate Altitude, Lara Rodríguez-Zamora, Paulino Padial, Brad Jon Schoenfeld, Belén Feriche

Publications and Research

We examined the viability of using mean propulsive velocity (MPV) to adjust the load in the countermovement jump (CMJ) at moderate altitude. Twenty-four volunteers were assigned to a 4-week power-oriented resistance training (R_T) program in either normoxia (N, 690m) or intermittent hypobaric hypoxia (IH, 2,320m). The load was adjusted to maintain execution velocity of CMJ at 1m·s⁻¹ of MPV. Relative peak power output (P_rel), and percentage of velocity loss throughout the sets (VL) were determined for each session. The internal load was measured by the rating of perceived exertion (RPE). The absolute load lifted was …

From The Human To The Planetary: Speculative Futures Of Care, Miriam Ticktin

Publications and Research

This is largely a theoretical, speculative essay that takes on the question of what ‘care’ looks like at a moment when climate change is increasingly taking center stage in public and political discussions. Starting with two new practices, namely, humanitarian care for nonhumans and One Health collaborations, I seek to determine what forms of political care can incorporate the well-being of future generations and future iterations of the earth. After an exploration of One Health as an approach to planetary care, I ask what its parts enable us to think, despite its limitations; I focus on the new human-nonhuman assemblages …

Invertebrate Retinal Progenitors As Regenerative Models In A Microfluidic System, Caroline D. Pena, Stephanie Zhang, Robert Majeska, Tadmiri Venkatesh, Maribel Vazquez

Publications and Research

Regenerative retinal therapies have introduced progenitor cells to replace dysfunctional or injured neurons and regain visual function. While contemporary cell replacement therapies have delivered retinal progenitor cells (RPCs) within customized biomaterials to promote viability and enable transplantation, outcomes have been severely limited by the misdirected and/or insuffcient migration of transplanted cells. RPCs must achieve appropriate spatial and functional positioning in host retina, collectively, to restore vision, whereas movement of clustered cells differs substantially from the single cell migration studied in classical chemotaxis models. Defining how RPCs interact with each other, neighboring cell types and surrounding extracellular matrixes are critical to …

Specific Effects Of Antitumor Active Norspermidine On The Structure And Function Of Dna, Takashi Nishio, Yuko Yoshikawa, Chwen-Yang Shew, Naoki Umezawa, Tsunehiko Higuchi, Kenichi Yoshikawa

Publications and Research

We compared the effects of trivalent polyamines, spermidine (SPD) and norspermidine (NSPD), a chemical homologue of SPD, on the structure of DNA and gene expression. The chemical structures of SPD and NSPD are different only with the number of methylene groups between amine groups,[N-3-N-4-N] and [N-3-N-3-N], respectively. SPD plays vital roles in cell function and survival, including in mammals. On the other hand, NSPD has antitumor activity and is found in some species of plants, bacteria and algae, but not in humans. We found that both polyamines exhibit biphasic effect; enhancement and inhibition on in vitro gene expression, where SPD …

Snap At The Community Scale: How Neighborhood Characteristics Affect Participation And Food Access, Nevin Cohen

Publications and Research

Cities are spatially diverse, with enclaves of particular demo- graphic groups, clusters of businesses, and pockets of low-income individuals living amid affluence.

This essay presents data from New York City to illustrate the importance of measuring and addressing neighborhood characteristics that affect Sup- plemental Nutrition Assistance Program (SNAP) participation and the purchasing power of SNAP benefits: pockets of “eligible-but-not-enrolled” in- dividuals, proximity between SNAP participants and jobs, and variations in food prices across neighborhoods.

It concludes with 5 exam- ples of how addressing these community-scale issues can increase SNAP participation and food access.
