Abstract
We have used the upgraded Giant Metrewave Radio Telescope to carry out a deep (117 on-source hours) L-band observation of the Extended Groth Strip, to measure the average neutral hydrogen (H i) mass and median star formation rate (SFR) of star-forming galaxies, as well as the cosmic H i mass density, at 0.2 < z < 0.4. This was done by stacking the H i 21 cm emission and the rest-frame 1.4 GHz radio continuum from 445 blue star-forming galaxies with M
B ≤ −17 at z
mean ≈ 0.34. The stacked H i 21 cm emission signal is detected at ≈7σ significance, implying an average H i mass of

H i
= (≈9) Gyr, consistent with values in star-forming galaxies in the local universe. This indicates that the star formation efficiency does not change significantly over the redshift range 0–0.4. We used the detection of the stacked H i 21 cm emission signal to infer the normalized cosmic H i mass density (ρ

Published: September 2019

ABSTRACTThe tongue is an important oral structure that affects speech, position of teeth, periodontal tissues, nutrition, swallowing, nursing, and certain social activities. Ankyloglossia or tongue-tie, is a congenital anomaly characterized by an abnormally short lingual frenulum, which restricts mobility of the tongue. Though the ankyloglossia is not a serious condition, it may lead to a host of problems including infant feeding difficulties, speech disorders, and various mechanical and social issues related to the inability of the tongue to protrude. Hence, management of ankyloglossia should be considered at any age considering the risk-benefit evaluation. Tongue being highly vascular and mobile structure, laser-assisted lingual frenectomy is the simplest, safest and less traumatic of all the treatment modalities available, with most promising results in minimally invasive dentistry. Here, a case of ankyloglossia is reported with its management by diode laser.

Variation of the latissimus dorsi
Authors: Shah Ishani P , Yadav Amit , Mehta Rujuta , Thatte Mukund 
Published: September 2019

ABSTRACTA typical muscle variation of latissimus dorsi - the axillary arch is represented by the muscular or fibromuscular slip detached from the anteroinferior border of the musculus latissimus dorsi passing over the axilla under the axillary fascia crossing the medial side of the brachial plexus to continue as a septum intermusculare mediale brachii distally to the medial epicondyle of humerus. The full extent of the muscle is rarely present. Slips of muscle extend from the latissimus dorsi at the inferior angle of scapula to insert into pectoralis major (Langer), coracobrachilis, biceps or coracoid process forming what is described as a common variant - the muscular axillary arch. We report three cases of variants of latissimus dorsi, one of which has not been reported in the literature before.
A pregnant patient with fetal distress with severe post burn contracture of anterior trunk and perineum: A surgeon’s nightmare!
Authors: Vathulya Madhubari , Joshi Meenakshi 
Published: September 2019

ABSTRACT
Introduction: A case report of a pregnant lady in the third trimester, presenting in the emergency with absent fetal movements is being described. A multi-speciality expertise was involved and a full term female baby was delivered. Presentation: The patient presented in a Government hospital, Dehradun, India. At the time of presentation the fetal heart sounds were absent and subsequently the severe post-burn deformity involving the anterior trunk, perineum and thighs were discovered. Management: Immediately a multi-speciality approach involving the plastic, obstetrics and pediatrics field were called for and an emergency caesarean with simultaneous contracture release with split skin grafts were performed after optimizing the patient for surgery. Conclusion: This is one of the first case reports reporting this rare combination of post burn contracture of trunk and perineum with fetal distress requiring emergency caesarean section along with release of abdominal and perineal post-burn contracture. This case interestingly reinforces that in such complicated cases a systematic and a combined multi-speciality approach still holds the key to patient’s treatment even in district hospitals.

ABSTRACTTongue plays a pivotal role in both physiological and functional life of human beings. Structural and developmental abnormalities of the tongue in various forms have been reported in isolation or in combination with various syndromes. Though cases of bifid tongues have been mentioned in literature, no reports of pentafid tongue have been reported till date. Here we describe a unique case of congenital pentafid tongue along with bilateral polydactyly and its surgical management.
The Category of Ordered Bratteli Diagrams
Authors: Amini Massoud , Elliott George A. , Golestani Nasser 
Published: September 2019

AbstractA category structure for ordered Bratteli diagrams is proposed in which isomorphism coincides with the notion of equivalence of Herman, Putnam, and Skau. It is shown that the natural one-to-one correspondence between the category of Cantor minimal systems and the category of simple properly ordered Bratteli diagrams is in fact an equivalence of categories. This gives aBratteli–Vershik modelfor factor maps between Cantor minimal systems. We give a construction of factor maps between Cantor minimal systems in terms of suitable maps (called premorphisms) between the corresponding ordered Bratteli diagrams, and we show that every factor map between two Cantor minimal systems is obtained in this way. Moreover, solving a natural question, we are able to characterize Glasner and Weiss’s notion of weak orbit equivalence of Cantor minimal systems in terms of the corresponding C*-algebra crossed products.
Low-cost eddy covariance: a case study of evapotranspiration over agroforestry in Germany
Authors: Markwitz Christian , Siebicke Lukas 
Published: September 2019

Abstract. Heterogeneous land surfaces require multiple measurement units for spatially adequate sampling and representative fluxes. The complexity and cost of traditional eddy covariance (EC) set-ups typically limits the feasible number of sampling units. Therefore, new low-cost eddy covariance systems provide ideal opportunities for spatially replicated sampling. The aim of this study was to test the performance of a compact, low-cost pressure, temperature and relative humidity sensor for the application of evapotranspiration measurements by eddy covariance over agroforestry and conventional agriculture in Germany. We performed continuous low-cost eddy covariance measurements over agroforestry and conventional agriculture for reference at five sites across northern Germany over a period of 2 years from 2016 to 2017. We conducted side-by-side measurements using a roving enclosed-path eddy covariance set-up to assess the performance of the low-cost eddy covariance set-up. Evapotranspiration measured with low-cost eddy covariance compared well with fluxes from conventional eddy covariance. The slopes of linear regressions for evapotranspiration comparing low-cost and conventional eddy covariance set-ups ranged from 0.86 to 1.08 for 5 out of 10 sites, indicating a 14 % flux underestimation and a 8 % flux overestimation relative to the conventional eddy covariance set-up, respectively. Corresponding coefficients of determination, R2, ranged from 0.71 to 0.94 across sites. The root-mean-square error for differences between latent heat fluxes obtained by both set-ups were small compared to the overall flux magnitude, with a mean and standard deviation of 34.23±3.2 W m−2, respectively, across sites. The spectral response characteristics of the low-cost eddy covariance set-up were inferior to the eddy covariance set-up in the inertial sub-range of the turbulent spectrum. The water vapour flux co-spectrum of the low-cost eddy covariance set-up underestimated the theoretical slope of -4/3, stronger than the conventional eddy covariance set-up. This underestimation was mainly caused by the limited response time of the low-cost thermohygrometer being longer than 1 s. We conclude that low-cost eddy covariance sensors are an alternative to conventional eddy covariance sensors when, first, replicates are required and, second, the spatial variability of fluxes of the ecosystems of interest is larger than above-reported set-up-specific differences in fluxes.
How can geologic decision-making under uncertainty be improved?
Authors: Wilson Cristina G. , Bond Clare E. , Shipley Thomas F. 
Published: September 2019

Abstract. In the geosciences, recent attention has been paid to the influence of uncertainty on expert decision-making. When making decisions under conditions of uncertainty, people tend to employ heuristics (rules of thumb) based on experience, relying on their prior knowledge and beliefs to intuitively guide choice. Over 50 years of decision-making research in cognitive psychology demonstrates that heuristics can lead to less-than-optimal decisions, collectively referred to as biases. For example, the availability bias occurs when people make judgments based on what is most dominant or accessible in memory; geoscientists who have spent the past several months studying strike-slip faults will have this terrain most readily available in their mind when interpreting new seismic data. Given the important social and commercial implications of many geoscience decisions, there is a need to develop effective interventions for removing or mitigating decision bias. In this paper, we outline the key insights from decision-making research about how to reduce bias and review the literature on debiasing strategies. First, we define an optimal decision, since improving decision-making requires having a standard to work towards. Next, we discuss the cognitive mechanisms underlying decision biases and describe three biases that have been shown to influence geoscientists' decision-making (availability bias, framing bias, anchoring bias). Finally, we review existing debiasing strategies that have applicability in the geosciences, with special attention given to strategies that make use of information technology and artificial intelligence (AI). We present two case studies illustrating different applications of intelligent systems for the debiasing of geoscientific decision-making, wherein debiased decision-making is an emergent property of the coordinated and integrated processing of human–AI collaborative teams.
In Search of Pedigrees: Why Do We Harm the Dogs We Love?
Authors: Lockwood Randall 
Published: September 2019

Abstract
Michael Brandow provides a unique analysis of the rise of the “dog fancy” in the United States and the United Kingdom. He attributes much of the motivation to acquire, breed, and show prestigious pure-bred dogs to a human need for status at the cost of serious detriment to the health and welfare of the many breeds developed to meet these needs. Although the many problems associated with the production of such dogs have been increasingly recognized by the veterinary and animal welfare communities, such concerns have had relatively little impact on the popularity of these dogs. It is hoped that greater awareness of the harm to dogs caused by human vanity and greed may help foster a more humane human-canine relationship.
Free, Prior, and Informed Consent: The Olympic Movement’s International Responsibilities to Indigenous Peoples in Canada and across the Globe
Authors: O’Bonsawin Christine 
Published: September 2019

AbstractOver the last half-century, the rights of Indigenous peoples have been recognized and engraved within international practice and law. Throughout this same period, the International Olympic Committee (IOC) has not expressed its readiness, or its willingness, to observe such developing ethical and legal principles. Subsequently, through the hosting of the Olympic Games, the IOC continues to move freely throughout the world and onto Indigenous lands. This paper argues that the IOC has legal and moral obligations—as an international organization with far-reaching powers and stated commitments to social responsibility, ethical principles, and the preservation of human dignity—to uphold international practices and laws concerning universal standards for the survival, dignity, well-being, and rights of Indigenous peoples. If the IOC accepts these responsibilities, it may begin to fulfill truthfully its mandate and start to make meaningful contributions to the advancement of the rights of Indigenous peoples in Canada and around the world.

“How does it feel to be a problem?” Black German Girlhood and the Historical Entanglements of Nation
Authors: Donaldson Sonya 
Published: September 2019

AbstractIn this comparative reading of Doris McMillon’s Mixed Blessing and Ika Hügel-Marshall’s Invisible Woman, I examine the ways that the authors use the autobiographical form to engage notions of black girlhood in both Germany and the United States. By focusing on their fractured family relationships—and their desire for a return to family, race, and nation—the authors reveal the ways in which national and transnational discourses demarcate the boundaries of racial and national belonging. The narratives return us to scenes of fraught personal and national histories to articulate experiences of subject-making that echo transnationally, while making visible the black girl’s body as a pivotal site of nation-state transformation.
In the Life: On Black Queer Kinship
Authors: Green Kai M. 
Published: September 2019

Abstract
In this short piece, the author stages a poetic and performative conversation between himself and the black queer figures he imagines as his chosen-family tree. This piece is an attempt to linger in the black queer inventiveness that is as much tethered to a real and imagined past as it is to all possible radical black futures.
Three Acts of Resistance during the 2014–16 West Africa Ebola Epidemic
Authors: Marcis Frédéric Le , Enria Luisa , Abramowitz Sharon , Saez Almudena-Mari , Faye Sylvain Landry B. 
Published: September 2019

Abstract
Community engagement is commonly regarded as a crucial entry point for gaining access and securing trust during humanitarian emergencies. In this article, we present three case studies of community engagement encounters during the West African Ebola outbreak. They represent strategies commonly implemented by the humanitarian response to the epidemic: communication through comités de veille villageois in Guinea, engagement with NGO-affiliated community leadership structures in Liberia and indirect mediation to chiefs in Sierra Leone. These case studies are based on ethnographic fieldwork carried out before, during and after the outbreak by five anthropologists involved in the response to Ebola in diverse capacities. Our goal is to represent and conceptualise the Ebola response as a dynamic interaction between a response apparatus, local populations and intermediaries, with uncertain outcomes that were negotiated over time and in response to changing conditions. Our findings show that community engagement tactics that are based on fixed notions of legitimacy are unable to respond to the fluidity of community response environments during emergencies.
Past Practice into Future Policy
Authors: O’Sullivan Kevin , Ní Chéilleachair Réiseal 
Published: September 2019

Abstract
This article describes the results of a pilot project on using historical reflection as a tool for policy-making in the humanitarian sector. It begins by establishing the rationale for integrating reflection into humanitarian practice. It then looks at the growing interest in humanitarian history among practitioners and academics over the past decade and sets out the arguments for why a more formalised discussion about humanitarianism’s past could result in a better understanding of the contemporary aid environment. The main body of the article focuses on our efforts to translate that potential into practice, through a reflective workshop on Somalia since the 1990s, held at National University of Ireland, Galway, in June 2017. Drawing on our experience of that event, the article puts forward four principles on which a workable model of reflective practice might be developed: the importance of the workshop setting, how to organise the reflective process, the value of pursuing a single case study and the careful management of expectations and outcomes. This article is not intended to be prescriptive, however. Rather, our aim is to put forward some practical suggestions and to open a conversation about how a model of historical reflection for aid practitioners might be developed.
Outdoor workers’ perceptions of skin cancer risk and attitudes to sun-protective measures: A qualitative study
Authors: Rocholl Marc , Ludewig Michaela , John Swen Malte , Bitzer Eva Maria , Wilke Annika 
Published: September 2019

Abstract

Objectives
Since January 2015, squamous cell carcinoma or multiple actinic keratosis of the skin caused by natural ultraviolet irradiation (UVR) is recognized as occupational disease in Germany. Interventions which improve the sun protection behavior of outdoor workers are urgently needed. When developing preventive interventions, the attitudes of target groups need to be taken into consideration. Therefore, outdoor workers’ perceptions and attitudes were investigated.

Methods
Seven guided, problem-centered qualitative interviews with healthy male outdoor workers were conducted. A qualitative content analysis was used to analyze the data.

Results
We found an underestimation of the perceived skin cancer risk in the seven outdoor workers and heterogeneous attitudes toward the usage of sun-protective measures. Participants stated that the feasibility of technical sun-protective measures depends on the size of the working area. While using a headgear seemed common, none of the participants stated using additional neck protection. Wearing long-sleeved shirts and long trousers were considered problematic. The interviews revealed important requirements for sun-protective clothes, especially in terms of different materials. Although the usage of sunscreen was common, our interviewees seemed to apply it wrongly.

Conclusion
Risk perceptions of outdoor workers and their attitudes toward sun protection measures may influence the factual UV protection behavior in the workplace. Structures to facilitate the implementation of technical and organizational sun-protective measures seem to be necessary. Educational interventions and clear instructions which are tailored to the individual needs and attitudes of outdoor workers are required to improve the UV protection behavior and to avoid common mistakes.
