A survey of bat communities in Grand Teton National Park in relation to anthropogenic structures and light
Authors: Cole Hunter J. 
Published: July 2020

Bats (order Chiroptera) are increasingly recognized as critical in diverse ecosystems around the world. However, there have been relatively few studies of bats in Grand Teton National Park (GRTE), such that a great deal remains to be learned about bat communities in the region. We recorded bat echolocation calls with acoustic monitoring device and analyzed recordings with species identification software to characterize bat communities in GRTE. These data, along with data on human-made structures and lightscapes around the park will be used to analyze relationships between bat communities and anthropogenic infrastructure within the park.

Investigating movement and population genetic structure of Parnassius clodius butterflies in Grand Teton National Park
Authors: Debinski Diane M. , McCombs Audrey L. 
Published: July 2020

Numerous species are responding to warming climate by shifting distributions northward and poleward. Butterflies have been instrumental in documenting such climate-induced range shifts. Parnassius clodius is a montane butterfly found throughout the Greater Yellowstone Ecosystem in metapopulations of disconnected dry, gravelly sagebrush meadows. Dispersal among metapopulations will likely strongly determine whether the species can move in response to changing climate. We collected P. clodius in 41 study sites spread throughout the GYE for which we also have occupancy data. Future analysis of genotyping-by-sequencing data for these 209 samples will help describe population structure across the landscape and identify potential landscape features that are barriers to movement for this species.

Authors: Sprayberry Jordanna D. H. , DeFino Rachel , Dillon Michael E. 
Published: July 2020

From late May through late June we monitored flowering phenology of all plants in four transects in Grand Teton National Park. We identified and collected blooming data on 25 species. In addition, we assessed both bumblebee species composition and foraging activity in the same transects. We captured queens from five different bumblebee species in vane traps. Observations of transects for forager activity yielded little data, and we recommend future studies employ walking transects.

Understanding and managing wildlife jams in national parks: An evaluation in Grand Teton National Park
Authors: Monz Christopher , Kidd Abigail M. 
Published: July 2020

As recreation and tourism in parks and protected areas continues to increase, managers face rising concerns of degradation of natural resources and the visitor experience. Many park visitors are seeking opportunities to view or photograph wildlife. Visitor behavior in prime wildlife-viewing areas often involves visitors parking along roadways and exiting their cars to view wildlife. This creates a phenomenon known as a “wildlife jam”, as visitors park informally along a roadway, often becoming pedestrians as they view wildlife, while other motorists attempt to drive through. To date, no studies have comprehensively investigated this phenomenon. Our study characterizes the nature of wildlife jams on the Moose-Wilson Road in Grand Teton National Park. Global Positioning System (GPS) technology was used to collect high-accuracy data on location and duration of the jams. Observations during jams characterize size (how many visitors and cars were involved) and visitor behaviors during jams. Preliminary results suggest that jam characteristics including presence of park staff, species involved, and location, can affect the duration, extent, and visitor behaviors that occur. Understanding the nature of these jams will enable park managers to minimize the potential negative effects of jams on wildlife and the visitor experience.

Using LiDAR imagery to locate historic-era homesteads and irrigation features of the Mormon Row, Antelope Flats, and dry farms historic landscapes, Grand Teton National Park, Teton County, Wyoming
Authors: Schroeder William 
Published: July 2020

GIS analysis of LiDAR imagery facilitated a modified NHPA Section 110 Class II survey and inventory performed in the summer of 2016 resulting in the identification of hundreds of fragmentary, relict, and extant cultural resources located in the vicinity of the Mormon Row Historic District (MRHD; 48TE1444) between June 6 and August 10, 2016. Correct identification and association of newly located cultural resources with persons, historic-era homesteads, and historic events is a complex and lengthy process requiring thorough artifact analysis and substantial background, ethnologic, and archival (contextual) research to make recommendations of significance, eligibility, and/or inclusion as contributing elements or not to the MRHD. Moving from the artifact scale to the site, feature, or historic district scale is a scalar process. Once at the site or historic district scale, it may be appropriate to ask whether the cultural resources can be addressed at a landscape scale, and ask new research questions such as: What if one were to consider all the cultural resources–prehistoric, historic, and natural–together? Are there theories and/or methodologies that can accommodate multiple layers of cultural resources and time frames and result in interpretations that are meaningful for present and future cultural resources management praxis?

Ultrashort inverted tapered silicon ridge-to-slot waveguide coupler at 1.55  µm and 3.392  µm wavelength
Authors: Butt M. A. , Khonina S. N. , Kazanskiy N. L. 
Published: July 2020

Herein, a compact and efficient inverted tapered ridge-to-slot
waveguide coupler design based on the
silicon-on-insulator platform is presented. The proposed device
consists of three segments such as ridge waveguide, inverted taper
segment, and slot waveguide. The coupling segment resembles a V shape,
which provides good mode-matching between the ridge and slot
waveguide. Two significant aspects of the proposed coupler design are
discussed. In the first part of the paper, the coupler design
optimized at 1.55 µm is suggested for optical interconnect. The
propagation loss and coupling efficiency of 1.69 dB/µm and 91% are
obtained for the 100 nm long tapered segment introduced between the
ridge waveguide and slot waveguide, respectively. This propagation
loss of the device includes the loss suffered by the ridge waveguide,
tapered segment, and slot waveguide. Our proposed device design can be
used in integrated optical platforms, where the efficient coupling of
light to slot waveguides is required. Whereas, in the second part, the
coupler design is optimized at the mid-infrared of 3.392 µm for an
evanescent field absorption methane gas sensor. Slot waveguide offers
excessive light–matter interaction due to its strong mode confinement
in the low index material. The evanescent field ratio of

∼

0.73

is obtained for the optimized
waveguide geometry. As a result, 3 dB decay in the transmitted power
can be obtained at 60% of gas concentration present in the ambient
medium.
In vivo imaging of the depth-resolved optic axis of birefringence in human skin
Authors: Li Qingyun , Sampson David D. , Villiger Martin 
Published: July 2020

Recent progress has enabled the reconstruction of the local
(i.e., depth-resolved) optic axis (OAx) of biological tissue from
measurements made with polarization-sensitive optical coherence
tomography (PS-OCT). Here we demonstrate local OAx imaging in healthy
human skin in vivo. The images reveal
dense, weaving patterns that are imperceptible in OCT intensity
tomograms or conventional PS-OCT metrics and that suggest a mesh-like
tissue organization, consistent with the morphology of dermal
collagen. Using co-registered polarization-sensitive optical coherence
microscopy, we furthermore investigated the impact of spatial
resolution on the recovered OAx patterns and confirmed their
consistency. OAx orientation as a contrast mechanism merits further
exploration for applications in dermatology.
India at the Venice Biennale: Collateral Events From and Beyond the Nation
Authors: Querol Nuria 
Published: July 2020

Abstract

iCon: India Contemporary (2005) was not only the first collateral event of India at the Venice Biennale, but it also began as a bid to become a national pavilion – an ambition that was ultimately unsuccessful. Drawing on original research and interview data surrounding the exhibition, this article examines the collaborations and conflicts between private art institutions, artists and the state in the context of India’s participation in the Venice Biennale since the 2000s. The article foregrounds a transversal approach – that is, an analytical framework that unsettles the conventional dichotomy between national pavilions and collateral events – and demonstrates how commercial galleries and private art institutions have acquired an important role in the production and exhibition of Indian contemporary art in global biennial circuits.
Possessing Nature: The Mexican Pavilion as a Site of Critical Analysis
Authors: González Rueda Ana Sol 
Published: July 2020

Abstract
This article examines the complexities of sustaining a critical curatorial approach in the context of the national pavilions at the Venice Biennale. It discusses Possessing Nature, the 2015 Mexican pavilion, from the author’s insider perspective as Project Coordinator. Curated by Karla Jasso, the exhibition presented an installation by Tania Candiani and Luis Felipe Ortega, and was conceived as a site of critical analysis focused on Venice’s and Mexico City’s environmental crises. This case study sheds light on the contradictory politics of the Biennale by exploring the challenges of introducing an experimental approach to mediation and of constructing the exhibition as a site of active research.
The impact of market drops is different for investors before and after retirement
Authors: Samsa Greg 
Published: July 2020

As applied to investing for and during retirement, the popular financial press has promulgated two memes about the impact of market drops: (1) for those investing for retirement market drops aren’t problematic; and (2) for those in retirement market drops are. We use simulation to illustrate the logic behind these memes, to demonstrate that they are mostly but not entirely true, and finally to restate them more precisely. Although sequence of returns risk is not present during the accumulation phase as an investor plans for retirement, it can have a significant (and perhaps underestimated) impact during retirement. This, however, can place the retiree in a predicament – namely, settle for lower returns and lower distributions during retirement or gamble on stocks. However, it does not necessarily imply that retirees must abandon the expected returns associated with stocks, because of the ability to write deep-in-the-money covered call options, which harvest the expected market return (but no more than this) with limited variability.
PPI inflation rate from 1% to 6% – Mathematical Reasoning of Economic Intervening Principle Based on Yin Yang Wu Xing Theory in Traditional Chinese Economics (II)
Authors: Zhang Yingshan 
Published: July 2020

PPI (Producer Price Index) is useful in understanding industry economic disease. By using mathematical reasoning based on Yin Yang Wu Xing Theory in Traditional Chinese Economics (TCE) or Traditional Chinese Science (TCS), this paper demonstrates that for the PPI inflation rate of industry economic society, the normal range of theory is nearly to . The first or second transfer law of economic diseases changes according to the different PPI inflation rate whether in the normal range or not. The treatment principle:“Don’t have economic disease cure cure non-ill” () is abiding by the first or second transfer law of economic diseases. Assume that the range of PPI inflation rate is divided into four parts from small to large. Both second and third are for a healthy economy. Our works are the prevention or treatment for a more serious relation economic disease which comes from the first transfer law. And both first and fourth are for an unhealthy economy. Our works are the prevention or treatment for a more serious relation economic disease which comes from the second transfer law. Economic disease treatment should protect and maintain the balance of two incompatibility relations: the loving relationship and the killing relationship.

Published: July 2020

Stunting is a condition of nutritional deficiencies caused by insufficient long-term nutritional intake. It is estimated that one in four children under the age of five fails to grow along the optimal trajectory set in the World Health Organization's Child Growth Standards. This study aims to find a model of reducing the prevalence of stunting in children under five in the city of Palembang through processing household waste. This research was an analytic observational study through a quantitative approach and cross-sectional study design. In this study, the population is all mothers who have children under five (0-59 months) who check the condition of their children in the working area of ​​Palembang city health center. Each increase in 1 unit of perception of seriousness increases 0.074 units of Securing Household Waste Behavior (p value = 0.024) On the perception of benefits obtained every increase of 1 unit it will increase 0.135 units of Securing household waste behavior (p value = 0.001). Every increase of 1 unit of perception of eating problems will decrease 0.067 units of Securing Household Waste Behavior (p value = 0.049). Cue unit to act increases 0.078 units of CTPS behavior (p value = 0.023) Every increase of 1 unit of ability / efficacy increases 0.518 units of Securing household waste behavior (p value = 0.001). Each increase of 1 unit of Securing Household Waste Behavior will decrease stunting of 0.071 units (p-value = 0.039) From this study conclusions can be drawn from the perception of vulnerability, perception of seriousness, perceived usefulness, gestures to act, ability / self-efficacy has influence uh positive about household waste management behavior, but the perception of obstacles has a negative influence on Securing household waste. The most influential component of gesture for action is family support.

Authors: Saraee Soheila , Shabani Somayeh , Pasnak Robert 
Published: July 2020

A life skills questionnaire was developed based on existing theories. The content validity of the questions was evaluated by educational experts. The resulting life skills questionnaire had 83 questions and ten subscales: empathy, emotion regulation, self-awareness, problem solving, effective communication, interpersonal communication, stress and critical thinking, creative thinking and decision making. It had good reliability (r = .91) and validity. The confirmatory factor analysis confirmed the proposed ten factor model of the questionnaire. Given its reliability and validity, this scale of life skills can be used as a tool by researchers.
Operational alteration of the Labor Capacity Index measurement model for qualitative work
Authors: Linke Knut 
Published: July 2020

The Marx term Labour capacity contains the ability to handle change, imponderables and complexity and is personal part of an employee. The Labour Capacity Index (LCI) is developed to measure the use of labour capacity at work places and from employee itself. The index helps to understand the handling and dealing of complexity and imponderables at work. For the index itself is assumed that the index itself news small adjustment to be more valuable.
A critic point of the LCI seems to be the existing scale and the used values, do to limitations on the available record set. This paper displays the results of a hopeful useful change in the operationalization of the measurement of labour capacity to increase the understanding of workers and their personal and experienced input to work. The comparison of the results is based on a survey with the working environment of IT employees.
From the analysis of the results and out of the following comparison between the new and the old approach for the LCI, it can be displayed that the change in the operationalization can be done successfully. The including of new variable values also allowed a more detailed and distributes view on the labour market and the research labor capacity.
Collective Teacher Efficacy: A Critical Review of Education's Top Influence
Authors: Hoogsteen T.J. 
Published: July 2020

Statements claiming that efforts of policy makers, system and school leaders, and staff developments toward education reforms might be better served by strategically and intentionally considering how to foster collective efficacy throughout the conceptualization, design, delivery, and assessment of change initiatives (Donohoo, 2018, p. 340) require continued attempts to provide critical reviews of the available literature, as does this review. Furthermore, Donohoo (2018) discussed the need for reviews of research to examine what is known about the causal directions amongst the outcomes of collective efficacy, and the current article does this as well. This is especially important and timely considering that collective teacher efficacy (CTE) is regarded by many as the top influence on student achievement. This review undertakes an examination of articles related to CTE and achievement, leadership, teacher outcomes, and professional learning communities. It draws attention to important future directions for collective efficacy research as well as valuable insights for school and district leaders responsible for determining school and system priorities.

Curves in the Lorentz-Minkowski plane with curvature depending on their position
Authors: Castro Ildefonso , Castro-Infantes Ildefonso , Castro-Infantes Jesús 
Published: July 2020

Abstract
Motivated by the classical Euler elastic curves, David A. Singer posed in 1999 the problem of determining a plane curve whose curvature is given in terms of its position. We propound the same question in the Lorentz-Minkowski plane, focusing on spacelike and timelike curves. In this article, we study those curves in

L

{{\mathbb{L}}}^{2}

whose curvature depends on the Lorentzian pseudodistance from the origin, and those ones whose curvature depends on the Lorentzian pseudodistance through the horizontal or vertical geodesic to a fixed lightlike geodesic. Making use of the notions of geometric angular momentum (with respect to the origin) and geometric linear momentum (with respect to the fixed lightlike geodesic), respectively, we get two abstract integrability results to determine such curves through quadratures. In this way, we find out several new families of Lorentzian spiral, special elastic and grim-reaper curves whose intrinsic equations are expressed in terms of elementary functions. In addition, we provide uniqueness results for the generatrix curve of the Enneper surface of second kind and for Lorentzian versions of some well-known curves in the Euclidean setting, like the Bernoulli lemniscate, the cardioid, the sinusoidal spirals and some non-degenerate conics. We are able to get arc-length parametrizations of them and they are depicted graphically.

Chelating polymers with valuable sorption potential for development of precious metal recycling technologies
Authors: Tofan Lavinia , Wenkert Rodica 
Published: July 2020

Abstract
A special attention is currently focused on the recovery of Au, Ag, Pt, Pd and Rh from both primary and secondary sources. From the wide range of sorbents that have been used in this respect, the required selectivity is proved only by the chelating polymers containing donor N, O and S atoms in their functional groups. This work presents the recent published researches on this topic, pointing out the capabilities of chelating sorbents based on organic synthetic polymers for a sustainable development. The chelating sorbents are differentiated and reviewed according to their synthesis strategy and compatibility with synthetic and real matrices. First, an overview on the novel functionalized polymers and impregnated resins with good selectivity for the recovery of most valuable precious metals from synthetic leach solutions is given. Subsequently, the performances of these materials in the selective and preconcentrative recovery of Au, Ag, Pt, Pd and Rh from simulated and real leachates are discussed. The viability of an integrated approach for the determination of precious metals from simulated solutions by solid phase spectrometry is highlighted. The transposition of chelating polymers’ potential in challenging technologies for precious metal recovery-reuse-recycling needs further research on directions that are proposed.
Practical Postexercise Recovery Strategies in Male Adult Professional Soccer Players: A Systematic Review
Authors: Ribeiro João , Sarmento Hugo , Silva Ana F. , Clemente Filipe M. 
Published: July 2020

ABSTRACT
The aim of this article was to systematically review and provide practical recommendations, where possible, for recovery strategies that are currently in use in soccer-specific practices among adult male professional players. A systematic search was conducted according to PRISMA guidelines on Web of Science, SPORTdiscus, Scopus, and PubMed databases. The effects of cold-based recovery techniques on performance recovery and attenuating the muscle soreness were evident. Complementarily, some evidence was found that favors foam rolling and massage and compression garments. The active recovery and electronic recovery instruments presented little evidence supporting their usefulness in accelerating the recovery process of soccer players.
