Published: December 2019

AbstractWe evaluated the effects of air exposure on Yellowstone Cutthroat Trout Oncorhynchus clarkii bouvieri caught and released in a cold-water stream with elevated water temperatures (i.e., &gt; 14°C) in southeastern Idaho. Anglers caught fish in a 2.3-km section of Fall Creek, Idaho, during August 2018. Sampled fish remained underwater while we measured and then tagged them with T-bar anchor tags. We exposed fish to air for 0, 30, or 60 s and then released them at the point of capture. We continuously monitored temperature during the study period. Water temperatures during the study varied from 10.0 to 19.7°C and averaged 14.9°C (SE = 0.08). In total, anglers caught 161 Yellowstone Cutthroat Trout over 10 d. Of those fish, we did not expose 54 to air; we exposed 54 to air for 30 s, and 53 for 60 s. We used electrofishing to recapture tagged fish and estimate relative survival. Relative survival was highest for fish exposed to air for 60 s (0.40 [SE = 0.25]) followed by 0 s (0.35 [SE = 0.25]) and 30 s (0.30 [SE = 0.27]), but differences were not statistically significant. Results from this study are consistent with other air-exposure studies suggesting that air exposure of 60 s or less is not likely a concern in Yellowstone Cutthroat Trout fisheries. Releasing fish as quickly as possible is always encouraged, but management regulations restricting air exposure seem unnecessary given the collective body of field-based research on air exposure. Nevertheless, similar studies on other systems and species are warranted.
Developing Rigorous Monitoring Programs: Power and Sample Size Evaluations of a Robust Method for Monitoring Bird Assemblages

Published: December 2019

AbstractWildlife population monitoring programs are useful for identifying ecological impacts such as those from local management actions and broader scale influences such as climate change. Increasing the number of species monitored improves robustness of the program towards meeting monitoring objectives. In addition, monitoring at multiple spatial scales should increase the sensitivity of the monitoring program. We developed a monitoring program using unbiased estimates of occupancy at both local and regional scales, and unbiased estimates of density for multiple species of birds with a single protocol. We used transects for sampling ∼1,000-ha pastures that consisted of twelve 200-m radius sampling points. We conducted 10-min point counts and recorded distance to each observation using two independent observers, and resampled each of 30 transects over two study sites in South Texas, for a total of four visits in each of 2015 and 2016. We estimated occupancy at two scales using the multiscale model in Program MARK and estimated density using the Distance package in R. We predicted that it would be possible to detect a 50% decline over 25 y with a power of 0.90 in regional occupancy, local occupancy, and density for 36, 37, and 30 species, respectively, on our larger study site, and for 29, 33, and 12 species, respectively, on our smaller study site using two independent observers and four visits. Our work shows it is possible to monitor numerous species within a complex bird assemblage with a simple field protocol. For those interested in implementing a long-term monitoring program that is sensitive to a wide range of potential stressors at local and regional scales, we suggest considering multiscale occupancy and density monitoring for multiple species of birds.
Sampling the Central Channel Provides Additional Information on Fish Assemblages in a Large Boatable River in the U.S. Midwest
Authors: Cao Yong , Parker Jerrod , Edison Tim , Epifanio John 
Published: December 2019

Abstract
It is a challenge to adequately characterize the fish assemblages of large rivers because of their sizes and high spatial–temporal habitat heterogeneity. Multiple sampling methods are often needed, but their uses increase cost and present difficulty for data standardization. In this study, we examined how much new information central-channel electrofishing sampling could add to typical shoreline electrofishing in a large and relatively shallow river, the lower Wabash River, in the U.S. Midwest. We found that the two types of samples differed markedly in species composition, and each was strongly associated with a subset of species. Shoreline samples captured more fish individuals and species, and reached higher functional diversity, but central-channel samples often captured several large benthivore and migratory species such as Redhorse and Shovelnose Sturgeon. Central-channel electrofishing appears to be a quick and low-cost method to supplement shoreline sampling in monitoring and assessing large shallow rivers.
Temporal Trends in Body Condition of Arctic Geese Wintering in the Mississippi Alluvial Valley

Published: December 2019

AbstractMidcontinent populations of arctic nesting geese (hereafter, arctic geese), including greater white-fronted geese Anser albifrons frontalis, lesser snow geese Anser caerulescens caerulescens, and Ross's geese Anser rossii, have increased in abundance and shifted their winter distribution in recent decades. Consequently, the number of arctic geese wintering in the Mississippi Alluvial Valley (MAV) has increased since the 1980s. Stored endogenous nutrients are critically important to the life cycle of arctic geese as the geese use these stored nutrients to complete long-distance migration events, survive harsh winters, and supplement nutrients needed for reproduction. This study tracked temporal changes in body condition of arctic geese during the wintering period. We collected arctic geese from October–February 2015–2016 and 2016–2017 in eastern Arkansas. We used proximate analysis to determine size of lipid and protein stores as an index of body condition. Protein stores were more stable through time than lipids, but we observed a slight increase in all species as winter progressed. Mean lipid stores were dynamic and were highest in November and lowest in February. Greater white-fronted geese arrived earliest to the MAV and experienced an increase in endogenous lipid stores during early winter when high-energy food resources were most abundant. Conversely, snow and Ross's geese arrived to the MAV later and did not appear to increase their lipid stores upon arrival. All three species experienced a decline in stored lipid mass as winter progressed; a combination of factors such as resource depletion, a shift in dietary needs, physiological factors, hunting pressure, and increased energetic demands may have driven the decline. An improved understanding of the role that “nontraditional” wintering grounds exert on the nutrient dynamics of arctic geese may aid in the management of growing and shifting populations.
Effect of Habitat Management on Duck Behavior and Distribution During Spring Migration in Indiana

Published: December 2019

Abstract
Spring migration is an important life stage for ducks because their ability to find and acquire nutrients can affect subsequent reproductive success. Therefore, providing sufficient habitat to support the energetic needs of ducks and facilitate efficient feeding is a goal of habitat management and restoration. The rapid, unpredictable flood events that regularly occur in highly modified landscapes can make habitat management challenging and justify diverse management strategies. We examined the effect of habitat management on dabbling duck behavior and distribution during spring migration in southwest Indiana. We investigated three management options for wetlands: active management, passive management, and unmanaged agricultural food plots. We assessed duck behavior and density on 14 wetlands at Patoka River National Wildlife Refuge and Management Area. The agricultural food-plot areas had the lowest estimates of food availability followed by the actively managed areas; the passively managed wetlands had the greatest estimate. Dabbling duck density was greatest on the actively managed wetlands followed by food plots coming in second and passively managed wetlands third. Most dabbling ducks fed more intensively while on the passively managed wetlands followed by the actively managed and food-plot wetlands. Conservation prioritization of passively managed areas would provide larger areas for dabbling ducks to feed, but active management provides habitat regardless of climatic variability. Moving forward, wetland complexes encompassing diverse wetland management approaches would be the best option for spring-migrating waterfowl as these complexes can provide high-quality habitats and buffer against uncontrollable climactic conditions.

Abstract
Computationally optimized broadly reactive Ags (COBRA) targeting H1 elicit a broad cross-reactive and cross-neutralizing Ab response against multiple H1N1 viral strains. To assess B cell breadth, Mus musculus (BALB/c) Ab-secreting cells elicited by a candidate COBRA hemagglutinin (HA) (termed P1) were compared with Ab-secreting cells elicited by historical H1N1 vaccine strains. In addition, to evaluate the Ab response elicited by P1 HA at increased resolution, a panel of P1 HA-specific B cell hybridomas was generated following immunization of mice with COBRA P1 and the corresponding purified mAbs were characterized for Ag specificity and neutralization activity. Both head- and stem-directed mAbs were elicited by the P1 HA Ag, with some mAbs endowed with Ab-dependent cell-mediated cytotoxicity activity. P1 HA-elicited mAbs exhibited a wide breadth of HA recognition, ranging from narrowly reactive to broadly reactive mAbs. Interestingly, we identified a P1 HA-elicited mAb (1F8) exhibiting broad hemagglutination inhibition activity against both seasonal and pandemic H1N1 influenza strains. Furthermore, mAb 1F8 recognized an overlapping, but distinct, epitope compared with other narrowly hemagglutination inhibition–positive mAbs elicited by the P1 or wild-type HA Ags. Finally, P1 HA-elicited mAbs were encoded by distinct H chain variable and L chain variable gene segment rearrangements and possessed unique CDR3 sequences. Collectively, the functional characterization of P1 HA-elicited mAbs sheds further insights into the underlying mechanism(s) of expanded Ab breadth elicited by a COBRA HA-based immunogen and advances efforts toward design and implementation of a more broadly protective influenza vaccine.

Abstract
During prolonged exposure to Ags, such as chronic viral infections, sustained TCR signaling can result in T cell exhaustion mediated in part by expression of programmed cell death–1 (PD-1) encoded by the Pdcd1 gene. In this study, dynamic changes in histone H3K4 modifications at the Pdcd1 locus during ex vivo and in vivo activation of CD8 T cells suggested a potential role for the histone H3 lysine 4 demethylase LSD1 in regulating PD-1 expression. CD8 T cells lacking LSD1 expressed higher levels of Pdcd1 mRNA following ex vivo stimulation as well as increased surface levels of PD-1 during acute, but not chronic, infection with lymphocytic choriomeningitis virus (LCMV). Blimp-1, a known repressor of PD-1, recruited LSD1 to the Pdcd1 gene during acute, but not chronic, LCMV infection. Loss of DNA methylation at Pdcd1’s promoter-proximal regulatory regions is highly correlated with its expression. However, following acute LCMV infection, in which PD-1 expression levels return to near baseline, LSD1-deficient CD8 T cells failed to remethylate the Pdcd1 locus to the levels of wild-type cells. Finally, in a murine melanoma model, the frequency of PD-1–expressing tumor-infiltrating LSD1-deficient CD8 T cells was greater than in wild type. Thus, LSD1 is recruited to the Pdcd1 locus by Blimp-1, downregulates PD-1 expression by facilitating the removal of activating histone marks, and is important for remethylation of the locus. Together, these data provide insight into the complex regulatory mechanisms governing T cell immunity and regulation of a critical T cell checkpoint gene.

Published: December 2019

Background Neighborhood crime may be an important factor contributing to cardiovascular health disparities, and these relations may vary by race and sex. The present investigation evaluated (a) potential differential associations between neighborhood crime and cardiovascular disease (CVD) risk factors within subgroups of African American (AA) and White men and women, and (b) potential mediation by negative affect. Design and methods Participants were 1,718 AAs and Whites (58% AA; 54% female; 59% above poverty; ages 30-64 years) living Baltimore, Maryland who completed the first wave of the Healthy Aging in Neighborhoods of Diversity across the Life Span study from 2004-2009. CVD risk factors included body mass index, total serum cholesterol, glucose, and systolic and diastolic blood pressure. A negative affect composite was comprised of self-reported depression, anxiety, anger, vigilance, and perceived stress. Hierarchical multiple regression analyses were used to examine associations between per capita overall and violent crime rates, negative affect, and CVD risk factors. Results There were significant associations of greater overall crime rate with higher fasting glucose ( b=.192, P<0.05), and greater violent crime rate with higher systolic ( b=86.50, P<0.05) and diastolic ( b=60.12, P<0.05) blood pressure in AA women, but not men. These associations were not explained by negative affect. In Whites, there were no significant associations of overall or violent crime rates with cardiovascular risk factors. Conclusions AA women may be particularly vulnerable to the negative impact of crime on cardiovascular risk. Preventative efforts aimed toward this group may help to deter the detrimental effects that living in a high crime area may have on one's cardiovascular health.
Toward a cognitive science of markets: economic agents as sense-makers
Authors: Johnson Samuel G.B. 
Published: December 2019

Abstract
Behavioral economics aspires to replace the agents of neoclassical economics with living, breathing human beings. Here, the author argues that behavioral economics, like its neoclassical counterpart, often neglects the role of active sense-making that motivates and guides much human behavior. The author reviews what is known about the cognitive science of sense-making, describing three kinds of cognitive tools—hypothesis-inference heuristics, stories, and intuitive theories—that people use to structure and understand information. He illustrates how these ideas from cognitive science can illuminate puzzles in economics, such as decision under Knightian uncertainty, the dynamics of economic (in)stability, and the voters’ preferences over economic policies. He concludes that cognitive science more broadly can enhance the explanatory and predictive quality of behavioral economic theories.
Assessment and Faculty Support: Fostering Collegial Community to Strengthen Professional Practice
Authors: Carpenter Rowanna L. , Fitzmaurice Celine 
Published: December 2019

Abstract
At its best, the assessment process can inspire meaningful and authentic conversations among faculty about their practice as teachers, about their students as learners, and about their hopes and frustrations with both. However, in the literature on assessment there is little attention given to how departments or universities can foster these conditions. In the experience of the authors, assessment's potential will not be realized without faculty support, and faculty support is most effective when guided by assessment. The success of both relies on a culture that respects faculty expertise and encourages inquiry and vulnerability. This article describes the history and current practice of assessment and faculty support in University Studies, a general education program at Portland State University. It reflects on the tension between authentic, faculty-engaged inquiry and approaches that call for quick change and accountability. It also considers the challenges of practicing assessment and faculty support with faculty representing a range of professional ranks and spanning multiple colleges and departments. Finally, it offers examples of assessment and faculty support efforts that foster collegial communities and critical reflection on individual and program-level practices.

Abstract
This article is an ethnodrama playscript that examines the role of positionality in an interdisciplinary general education program called University Studies at Portland State University. Drawing from both the literature and from the practice of critical reflection, the authors share their experiences as faculty members relative to their institutional and social positionalities. The authors perform this ethnodrama through the construction of this article for an audience of teaching faculty and administrators in higher education. Throughout the ethnodrama, the audience/readers are invited to interact with the playscript through prompted critical reflection on their own positionalities in their professional lives.
O fim inacabado do capitalismo: presos no emaranhado inevitável de contradições
Authors: Favoreto Ricardo Lebbos , Nogueira Arnaldo José França Mazzei 
Published: December 2019

Em "17 contradições e o fim do capitalismo", David Harvey estimula a dúvida quanto à naturalidade do capital e, ao mesmo tempo, desvenda mecanismos de funcionamento do capitalismo. A obra toma parte daquilo que o autor, em retrospecto, denomina “Projeto Marx”. Os trabalhos que o integram visam ampliar o acesso ao intricado pensamento marxista, cuja compreensão é prejudicada pela insipiência esteada na rejeição e nas distorções promovidas pela direita, pelo dogmatismo característico da esquerda sectária e pelo academicismo que o complica ainda mais. Na obra, Harvey escreve que se trata do “livro mais perigoso” que já escreveu.
Estimativa de potencial energético de biogás proveniente do aterro sanitário Tijuquinhas (município de Biguaçu/SC)
Authors: Fassoni-Andrade Alice César , Medeiros Rafael Basílio , Lisboa Henrique De Melo 
Published: December 2019

A maior parte dos resíduos sólidos urbanos (RSU) no Brasil é disposta de maneira inadequada, provocando impactos ambientais, sociais e de saúde pública. O metano, produto da degradação anaeróbia dos RSU, é considerado impactante por ser um gás de efeito estufa. Este gás, queimado ou aproveitado corretamente em aterros sanitários, para geração de energia, pode trazer retorno financeiro para a empresa administradora, além de minimizar impactos ambientais. O objetivo deste trabalho foi analisar o potencial energético do aterro sanitário de Biguaçu/SC utilizando as metodologias propostas pelo IPCC para estimativa teórica de produção de biogás. Constatou-se que o aterro de Biguaçu possui alta capacidade de geração de energia através do aproveitamento de metano, com potencial máximo de 5,26 MW em 2019, um ano após o encerramento do aterro.
Percepção ambiental dos estudantes jovens e adultos da educação básica (Programa EJA) de escolas públicas municipais
Authors: Costa Samuel 
Published: December 2019

A presente pesquisa objetivou avaliar a percepção ambiental dos estudantes jovens e adultos da educação básica (Programa EJA) das escolas da rede municipal da cidade de Araranguá (SC). Foi aplicado um questionário para 56 alunos do curso em questão. Para a análise referente às concepções de meio ambiente foram estabelecidas cinco categorias de concepções (romântica, utilitarista, abrangente, reducionista e sócio-ambiental). Para a análise das respostas das questões objetivas foi utilizado um padrão de contagem e para as objetivas com mais de uma resposta, foi utilizado o método de contagem/pontuação por incidência. Os resultados apontaram para a predominância de uma percepção ambiental pouco elaborada e de caráter “reducionista” e que os educandos apresentam grande interesse pelos temas ambientais. Além disso, há a disposição para participar de trabalhos e de ações de educação ambiental. Esses resultados reforçam a necessidade do envolvimento dos educandos da EJA por meio da inserção de práticas de educação ambiental no cotidiano escolar.

Danish dialogue particles in an interactional perspective
Authors: Steensig Jakob , Sørensen Søren Sandager 
Published: December 2019

In our paper, we give an overview over what is known about some of the most frequent interjections in Danish talk-in-interaction: ja (‘yes’), nej (‘no’), mm (‘mm’), nå (approximately ‘oh’), and okay (‘okay’). We review the CA/IL literature on these words, and we present our own exemplary analyses of single instances of these words in extracts from our corpus of recorded, naturally occurring Danish interactions. Based on this, we argue that sequential position, epistemics, and affiliation and alignment should be taken into account when describing and categorizing dialogue particles in talk-in-interaction. Prosody and other phonetic cues are important for the realization of the above dimensions and functions and we review what is known about prosodic and phonetic cues plus add some of our own observations, without launching a full phonetic and prosodic analysis.
Interjections, phonetics, and the body
Authors: Hougaard Tina Thode 
Published: December 2019

Emotive interjections are normally associated with the spoken language, but in this article, I will investigate the use of two interjections, åh ‘oh’ and puha ‘whew’ in written communication on Facebook – on the two Danish Facebook groups built around the illness and death of two young children in 2015: “Fighting for Magnus (Miv)” and “Commemorative site for Lærke Rønde Timm”. Interjections are understood as affective expressions because they reflect some of the bodily reactions and participatory investment of the followers of the two groups. The main argument in the article is that the participants write interjections as a way to deal with affective extraordinary experiences. Through phonetic analysis the interjections are seen as bodily felt and triggered reaction.
