The Atomistic Study on Thermal Transport of the Branched Cnt
Authors: Chen Wei-Jen , Chang I-Ling
Published: August 2020

In this research, the thermal transport behavior of the branched carbon nanotube (CNT) with T-junction was investigated using non-equilibrium molecular dynamics simulation. Both symmetric and asymmetric temperature-controlled simulations were imposed to evaluate how the heat flowed inside the branched CNT with three branches of equal length and same chirality. The branch length and strain effects on the heat flow were examined. In addition, the simulated heat flow was compared with the prediction made by conventional thermal circuit calculation based on diffusive phonon transport. The heat was observed to flow straight rather than sideway inside the branched CNT with T-junction under the asymmetric temperature setup; this finding contradicts the conventional thermal circuit calculation. There are two possible explanations for this phenomenon. One is ballistic phonon transport and the other is phonons have different interactions or scattering with the defective atomic configurations at the T-junction. Moreover, the tensile strain could tune the heat flow, a finding that might be useful in thermal management applications.
The wicked problem of climate change and interdisciplinary research: Tracking management scholarship's contribution
Authors: Wohlgezogen Franz , McCabe Angela , Osegowitsch Tom , Mol Joeri
Published: August 2020

Taking urgent action to combat climate change is a pivotal Sustainable Development Goal (SDG). Since it is closely intertwined with the other 16 goals, it is frequently characterized as a ‘wicked problem par excellence.’ Interdisciplinary research, i.e., research crossing disciplinary boundaries, offers promise for grappling with wicked problems, but also entails significant challenges to researchers. In this study, we use bibliometric methods to understand how management scholars have, over the course of four decades, straddled disciplinary boundaries and what impact their efforts have had on top-tier climate change research appearing in Science and Nature. We find that management scholarship on climate change (1) has grown significantly since the mid-2000s, (2) features substantial engagement with an interdisciplinary knowledge base, and (3) fails to attract the attention of climate change research within top-tier interdisciplinary journals. We discuss these findings with reference to the ongoing discourse on raising management scholarship's relevance and impact.
Movilidad y explotación de recursos terrestres por cazadores-recolectores costeros de Bahía Moat, costa sureste de Tierra del Fuego, Argentina
Authors: Alunni Daniela Verónica , Tivoli Angélica Montserrat , Zangrando Atilio Francisco
Published: August 2020

En este trabajo se discute la movilidad y uso del espacio terrestre por parte de los grupos cazadores-recolectores costeros que habitaron la Bahía Moat, en la costa sureste de Tierra del Fuego, Argentina. Para ello, se analizan las pautas de explotación del guanaco (Lama guanicoe), único animal terrestre que tuvo un rol significativo para la subsistencia y requirió planificación en términos logísticos para su aprovechamiento. Los conjuntos estudiados corresponden al Holoceno tardío y los restos óseos se analizan en función de distintos modelos y marcos de referencia que evalúan las modalidades de búsqueda, transporte y procesamiento de camélidos. Los resultados alcanzados permiten plantear que la organización espacial de las prácticas de subsistencia pudo haberse desarrollado a partir de un alto dinamismo entre la costa y el interior. El elevado consumo de guanacos, junto con los patrones de selección y transporte, sugiere que las partidas de caza hacia el interior y las zonas ecológicas adyacentes al litoral pudieron haber estado integradas logísticamente dentro de un sistema de movilidad residencial localizado geográficamente en la costa.
Early weaning: new insights on an ever-persistent problem in the dairy industry
Authors: Mikuš Tomislav , Marzel Rok , Mikuš Ornella
Published: August 2020

It is common practice in the dairy industry to separate the calf from the cow immediately after parturition, and in most parts of the world calves are housed individually during the milk-feeding period. Early and abrupt separation has major implications for the calf's physical and psychological development. In this Research Reflection short review we present and discuss the main housing systems and management practices regarding early weaning in today's dairy industry. Main benefits and disadvantages are critically addressed, and possible future research suggested. Furthermore, major policy issues related to consumers, scientific recommendations and economic performance of farms have been identified, as well as future drivers for more viable housing solutions for neonatal calves. This review serves as an introduction and preamble to the second section of this Special Issue, which is dedicated to cow-calf contact management systems.
Comparison of the efficacy of tea tree (Melaleuca alternifolia) oil with other current pharmacological management in human demodicosis: A Systematic Review
Authors: Lam Nelson Siu Kei , Long Xin Xin , Li Xuegang , Yang Li , Griffin Robert C , Doery James CG
Published: August 2020

Various treatments are found to be moderately effective in managingDemodex-related diseases except tea tree oil (TTO) and terpinen-4-ol (T4O), which showed superior miticidal and anti-inflammatory effects in numerous clinical studies. Their possible effects include lowering mite counts, relievingDemodex-related symptoms, and modulating the immune system. This review summarizes the current clinical topical and oral treatments in human demodicosis, their possible mechanisms of action, side-effects and resistance in treating this condition. TTO (especially T4O) is found to be the most effective followed by metronidazole, ivermectin and permethrin in managing the disease. This is because TTO has anti-parasitic, anti-bacterial, anti-fungal, anti-inflammatory and wound-healing effects. Furthermore, nanoTTO can even release its contents into fungus andPseudomonasbiofilms. Combinations of different treatments are occasionally needed for refractory cases, especially for individuals with underlying genetic predisposal or are immuno-compromised. Although the current treatments show efficacy in controlling theDemodexmite population and the related symptoms, further research needs to be focused on the efficacy and drug delivery technology in order to develop alternative treatments with better side-effects profiles, less toxicity, lower risk of resistance and are more cost-effective.
Mental health disorders and alcohol misuse among UK military veterans and the general population: a comparison study
Authors: Rhead Rebecca , MacManus Deirdre , Jones Margaret , Greenberg Neil , Fear Nicola T , Goodwin Laura
Published: August 2020

Background

For a small minority of personnel, military service can have a negative impact on their mental health. Yet no studies have assessed how the mental health of UK veterans (who served during the recent operations in Afghanistan or Iraq) compares to non-veterans, to determine if they are at a disadvantage. We examine the prevalence of mental disorders and alcohol misuse in UK veterans compared to non-veterans.

Methods

Veteran data were taken from the third phase of the King's Centre for Military Health Research cohort study (n = 2917). These data were compared with data on non-veterans taken from two large general population surveys: 2014 Adult Psychiatric Morbidity Survey (n = 5871) and wave 6 of the UK Household Longitudinal Study (UKHLS, n = 22 760).

Results

We found that, overall, UK veterans who served at the time of recent military operations were more likely to report a significantly higher prevalence of common mental disorders (CMD) (23% v. 16%), post-traumatic stress disorder (PTSD) (8% v. 5%) and alcohol misuse (11% v. 6%) than non-veterans. Stratifying by gender showed that the negative impact of being a veteran on mental health and alcohol misuse was restricted to male veterans. Being ill or disabled was associated with a higher prevalence of CMD and PTSD for both veterans and non-veterans.

Conclusion

Whilst the same sociodemographic groups within the veteran and non-veteran populations seemed to have an increased risk of mental health problems (e.g. those who were unemployed), male veterans, in particular, appear to be at a distinct disadvantage compared to those who have never served.
Exploring the dynamics of flagellar dynein within the axoneme with Fluctuating Finite Element Analysis
Authors: Richardson Robin A. , Hanson Benjamin S. , Read Daniel J. , Harlen Oliver G. , Harris Sarah A.
Published: August 2020

Flagellar dyneins are the molecular motors responsible for producing the propagating bending motions of cilia and flagella. They are located within a densely packed and highly organised super-macromolecular cytoskeletal structure known as the axoneme. Using the mesoscale simulation technique Fluctuating Finite Element Analysis (FFEA), which represents proteins as viscoelastic continuum objects subject to explicit thermal noise, we have quantified the constraints on the range of molecular conformations that can be explored by dynein-c within the crowded architecture of the axoneme. We subsequently assess the influence of crowding on the 3D exploration of microtubule-binding sites, and specifically on the axial step length. Our calculations combine experimental information on the shape, flexibility and environment of dynein-c from three distinct sources; negative stain electron microscopy, cryo-electron microscopy (cryo-EM) and cryo-electron tomography (cryo-ET). Our FFEA simulations show that the super-macromolecular organisation of multiple protein complexes into higher-order structures can have a significant influence on the effective flexibility of the individual molecular components, and may, therefore, play an important role in the physical mechanisms underlying their biological function.
A long view of cumulative technological culture
Authors: O'Brien Michael J. , Bentley R. Alexander
Published: August 2020

We agree that the emergence of cumulative technological culture was tied to nonsocial cognitive skills, namely, technical-reasoning skills, which allowed humans to constantly acquire and improve information. Our concern is with a reading of the history of cumulative technological culture that is based largely on modern experiments in simulated settings and less on phenomena crucial to the long-term dynamics of cultural evolution.
Refining our understanding of the “elephant in the room”
Authors: Whiten Andrew
Published: August 2020

The authors do the field of cultural evolution a service by exploring the role of non-social cognition in human cumulative technological culture, truly neglected in comparison with socio-cognitive abilities frequently assumed to be the primary drivers. Some specifics of their delineation of the critical factors are problematic, however. I highlight recent chimpanzee–human comparative findings that should help refine such analyses.
Shared intentionality shapes humans' technical know-how
Authors: Moll Henrike , Nichols Ryan , Pueschel Ellyn
Published: August 2020

Osiurak and Reynaud argue that cumulative technological culture is made possible by a “non-social cognitive structure” (sect. 1, para. 1) and they offer an account that aims “to escape from the social dimension” (sect. 1, para. 2) of human cognition. We challenge their position by arguing that human technical rationality is unintelligible outside of our species' uniquely social form of life, which is defined by shared intentionality (Kern & Moll 2017, Philosophical Psychology30(3):319–37; Tomasello 2019a, Becoming human: A theory of ontogeny. Cambridge, MA: Belknap Press).
New Caledonian crows afford invaluable comparative insights into human cumulative technological culture
Authors: Rutz Christian , Hunt Gavin R.
Published: August 2020

The New Caledonian crow may be the only non-primate species exhibiting cumulative technological culture. Its foraging tools show clear signs of diversification and progressive refinement, and it seems likely that at least some tool-related information is passed across generations via social learning. Here, we explain how these remarkable birds can help us uncover the basic biological processes driving technological progress.

Published: August 2020

Garra gotyla is an indigenous coldwater fish of the cyprinid family and has wide geographical distribution in India as well as in other countries of Asia and Africa. Induced breeding in G. gotyla was carried out successfully for the first time and an attempt has been made to document developmental stages chronologically from the first minute of fertilization, through all stages of embryonic development until the fifth day post hatching. This experiment was carried out at 22–24°C water temperature at the Directorate of Coldwater Fisheries Research, Bhimtal, India. During the breeding trial, the fertilization rate was observed as 70–75% and hatching rate was 85–90%. The mature fertilized ova were measured as 0.8–1.0 mm in diameter and the perivitelline membrane became thick soon after fertilization and formation of the germ pole. The periods taken for complete developmental stages were recorded; cleavage stage 111 min (min post fertilization (pf)), blastulation stage 580 min (pf), neurulation and segmentation 1250 min (pf) and hatching was completed after 1420 min. The sac fry was measured as 3 mm in length and took almost 3 days for complete absorption of the yolk content. The major structural and differential changes observed are in head, tail, fins, alimentary canal, rudiments of each organ and appearance of melanophore pigmentation in the whole body. The 5-day-old larvae were measured as 6 mm in length with almost every organ fully differentiated. The present study will be utilized for large-scale production of fingerlings for stock enhancement in rivers, lakes and possibilities of genetic improvement and manipulation at the embryonic stage.
Developmental potential of somatic and germ cells of hybrids betweenCarassius auratusfemales andHemigrammocypris rasborellamales

Published: August 2020

The cause of hybrid sterility and inviability has not been analyzed in the fin-fish hybrid, although large numbers of hybridizations have been carried out. In this study, we produced allo-diploid hybrids by cross-fertilization between female goldfish (Carassius auratus) and male golden venus chub (Hemigrammocypris rasborella). Inviability of these hybrids was due to breakage of the enveloping layer during epiboly or due to malformation with serious cardiac oedema around the hatching stage. Spontaneous allo-triploid hybrids with two sets of the goldfish genome and one set of the golden venus chub genome developed normally and survived beyond the feeding stage. This improved survival was confirmed by generating heat-shock-induced allo-triploid hybrids that possessed an extra goldfish genome. When inviable allo-diploid hybrid cells were transplanted into goldfish host embryos at the blastula stage, these embryos hatched normally, incorporating the allo-diploid cells. These allo-diploid hybrid cells persisted, and were genetically detected in a 6-month-old fish. In contrast, primordial germ cells taken from allo-diploid hybrids and transplanted into goldfish hosts at the blastula stage had disappeared by 10 days post-fertilization, even under chimeric conditions. In allo-triploid hybrid embryos, germ cells proliferated in the gonad, but had disappeared by 10 weeks post-fertilization. These results showed that while hybrid germ cells are inviable even in chimeric conditions, hybrid somatic cells remain viable.
Assessment of binder of sperm protein 1 (BSP1) and heparin effects on in vitro capacitation and fertilization of bovine ejaculated and epididymal sperm

Published: August 2020

The present study evaluated the effect of binder of sperm protein 1 (BSP1) and/or heparin on in vitro bovine capacitation and fertilization rates using epididymal and ejaculated bovine sperm. Frozen–thawed sperm were selected and used in the following treatments. Control group: Fert-TALP medium without heparin; heparin (HEP) group: Fert-TALP with heparin (10 UI/ml); BSP1 group: Fert-TALP medium with BSP1 (10 µg/ml for ejaculated sperm; 40 µg/ml for epididymal sperm); HEP + BSP1 group: Fert-TALP medium with heparin (5 UI/ml) and BSP1 (5 µg/ml for ejaculated sperm; 20 µg/ml for epididymal sperm) and determined in vitro capacitation rates in different interval times (0, 15, 30 and 60 min) using the chlortetracycline ﬂuorescence (CTC) method. Also, we evaluated the development rates of oocytes fertilized with ejaculated or epididymal sperm into the same treatments. Capacitation was greater and faster when ejaculated sperm were treated for 60 min with heparin compared with other treatments. However, developmental rates were similar in all treatments. For epididymal sperm, the treatments with BSP1 presented higher capacitation and fertilization rates compared with heparin (P < 0.05). The effects of heparin + BSP1 on capacitation and developmental rates did not cause any increase in capacitation or blastocyst rates compared with other groups for ejaculated or epididymal sperm. In conclusion, this study confirmed that either BSP1 and heparin can be used as capacitator agents for bovine ejaculated sperm during IVF. However, BSP1 seems to be more efficient compared with heparin for epididymal sperm. Furthermore, BSP1 and heparin have no synergic effects on sperm capacitation.

Authors: Lingaswamy Dasana , Koepcke Louisa , Krishna Mani Ram , Kottayil Brijesh P. , Sunil Gopalraj S. , Moynihan Katie , Seshadri Balaji , Kumar Raman Krishna
Published: August 2020

Background:

The optimal management of symptomatic tetralogy of Fallot in neonates and younger infants with unfavourable anatomy is unclear and is further constrained by resource limitations in low and middle income countries.

Methods:

Retrospective medical record review of infants with tetralogy of Fallot undergoing corrective or palliative procedures between January 2016 and June 2019.

Results:

The study included 120 infants; of whom 83 underwent primary complete repair, four underwent surgical palliation, and 33 underwent catheter-based palliation, including balloon pulmonary valvuloplasty (n = 18), right ventricular outflow tract stenting (n = 14), and stenting of the patent arterial duct (n = 1). Infants undergoing catheter-based procedures were younger in age (median 32 days; inter-quartile range (IQR) 7–144 versus 210 days; IQR 158–250), with lower baseline saturation (65 ± 12% versus 87 ± 7%) and had smaller pulmonary artery z-scores compared to the complete repair cohort. Follow-up was available for 31/33 (94%) infants (median 7 months [IQR 4–11]) who underwent trans-catheter palliation; 12 underwent complete repair, 10 are well, awaiting repair, eight required further palliation (catheter: 6; surgical: 2), and one died post-discharge from non-cardiac causes.

Conclusion:

Catheter-based palliation is a safe and effective alternative in infants with tetralogy of Fallot who are at high risk for primary surgical repair.
Qualitative Replication as a Pedagogical Approach to Teaching Research Methods
Authors: Becker Megan
Published: August 2020

The importance of replication has been a major matter of discussion among political scientists for decades. However, in the past five years, the issue has gained greater traction, with many major journals adopting official standards for Data Access and Research Transparency (DA-RT). At the same time, scholars suggest the pivotal role that replication might play in methods training for students. Unfortunately, these conversations have been limited in that they emphasize quantitative methods and training of graduate students. This article seeks to fill this gap by offering commentary on the author’s experience in introducing a qualitative replication project in an upper-division undergraduate course. The students in the course replicated Ross’s (2004) influential article on the “resource curse,” but the assignment framework can be adopted for various topics and contexts.
Conceptualizing, Measuring, and Explaining Youths’ Relative Absence in Legislatures
Authors: Sundström Aksel , Stockemer Daniel
Published: August 2020

This article conceptualizes the relative absence of youth in legislatures, a feature we perceive as a democratic deficit with detrimental consequences. It introduces a new operationalization: the Youth Representation Index. Rather than calculating youths’ representation by the percentage of Members of Parliament 35 or 40 years old and younger or legislatures’ median age, we argue that scholars should assess youths’ parliamentary presence relative to their proportion of the voting-age population. We contribute by assessing the magnitude of youths’ underrepresentation across countries, finding that adults 35 years old and younger are generally underrepresented in legislatures by a factor of three and those 40 years old and younger by a factor of two. We illustrate that youths’ presence increases under proportional representation electoral systems and with candidate age requirements set at 18 years. Finally, our results illustrate that countries with a younger population display a stronger discrepancy in youth representation.
Munchausen syndrome by proxy (MSBP): a review regarding perpetrators of factitious disorder imposed on another (FDIA)
Authors: Abdurrachid Nuzhat , Gama Marques João
Published: August 2020

Munchausen syndrome by proxy (MSBP) is well-known to clinicians, but its usage is discouraged now in favor of other terms placing emphasis on the victim. This study aims to determine the most common characteristics of perpetrators but only in case reports labeled as MSBP, published in PubMed literature in the past 15 years. MSBP has been described as a rare form of abuse due to illness falsification, where the perpetrator usually receives the diagnosis of factitious disorder imposed on another (FDIA). We extracted data from 108 articles, including 81 case reports. Almost all perpetrators were female (91% female, 1% female and male, 7% unreported). Twenty-three cases (28%) had a perpetrator with psychiatric diagnosis: factitious disorder imposed on self (10%), depression (9%), and personality disorders (7%). In more than one-third (36%) there was familial conflict or abuse. Fourteen cases (17%) had perpetrators working in healthcare. The most common type of falsification was induction (74%); however, 15% of cases had more than one type of falsification. The most common outcomes were: separation (37%); no follow-up (22%); imprisonment (14%); death of victim (12%); treatment of the perpetrator (10%); continued living together (4%); and suicide of perpetrator (1%). Recurrence was present in more than three quarters of cases. Our results reiterate that awareness of the most common findings in MSBP allows physicians to identify them in a clinical context.
The Effectiveness of Item-Specific Encoding and Conservative Responding to Reduce False Memories in Patients with Mild Cognitive Impairment and Mild Alzheimer’s Disease Dementia
Authors: Malone Christopher , Turk Katherine W. , Palumbo Rocco , Budson Andrew E.
Published: August 2020

Objective:

Patients with mild Alzheimer’s disease dementia are more susceptible to false memories than healthy older adults. Evidence that these patients can use cognitive strategies to reduce false memory is inconsistent.

Method:

In the present study, we examined the effectiveness of conservative responding and item-specific deep encoding strategies, alone and in combination, to reduce false memory in a categorized word list paradigm among participants with mild Alzheimer’s disease dementia (AD), amnestic single-domain mild cognitive impairment (MCI), and healthy age-matched older controls (OCs). A battery of clinical neuropsychological measures was also administered.

Results:

Although use of conservative responding alone tended to reduce performance in the MCI and OC groups, both deep encoding alone and deep encoding combined with conservative strategies led to improved discrimination for both gist memory and item-specific recollection for these two groups. In the AD group, only gist memory benefited from the use of strategies, boosted equally by deep encoding alone and deep encoding combined with conservative strategies; item-specific recollection was not improved. No correlation between the use of these strategies and performance on neuropsychological measures was found.

Conclusions:

These results suggest that further evaluation of these strategies is warranted as they have the potential to reduce related and unrelated memory errors and increase both gist memory and item-specific recollection in healthy older adults and individuals with amnestic MCI. Patients with AD were less able to benefit from such strategies, yet were still able to use them to reduce unrelated memory errors and increase gist memory.
Validation of the Virtual Reality Everyday Assessment Lab (VR-EAL): An Immersive Virtual Reality Neuropsychological Battery with Enhanced Ecological Validity
Authors: Kourtesis Panagiotis , Collina Simona , Doumas Leonidas A.A. , MacPherson Sarah E.
Published: August 2020

Objective:

The assessment of cognitive functions such as prospective memory, episodic memory, attention, and executive functions benefits from an ecologically valid approach to better understand how performance outcomes generalize to everyday life. Immersive virtual reality (VR) is considered capable of simulating real-life situations to enhance ecological validity. The present study attempted to validate the Virtual Reality Everyday Assessment Lab (VR-EAL), an immersive VR neuropsychological battery, against an extensive paper-and-pencil neuropsychological battery.

Methods:

Forty-one participants (21 females) were recruited: 18 gamers and 23 non-gamers who attended both an immersive VR and a paper-and-pencil testing session. Bayesian Pearson’s correlation analyses were conducted to assess construct and convergent validity of the VR-EAL. Bayesian t-tests were performed to compare VR and paper-and-pencil testing in terms of administration time, similarity to real-life tasks (i.e., ecological validity), and pleasantness.

Results:

VR-EAL scores were significantly correlated with their equivalent scores on the paper-and-pencil tests. The participants’ reports indicated that the VR-EAL tasks were significantly more ecologically valid and pleasant than the paper-and-pencil neuropsychological battery. The VR-EAL battery also had a shorter administration time.

Conclusion:

The VR-EAL appears as an effective neuropsychological tool for the assessment of everyday cognitive functions, which has enhanced ecological validity, a highly pleasant testing experience, and does not induce cybersickness.
A Multidimensional Assessment of Metacognition Across Domains in Multiple Sclerosis
Authors: Mazancieux Audrey , Moulin Chris J.A. , Casez Olivier , Souchay Céline
Published: August 2020

Objective:

In neurological diseases, metacognitive judgements have been widely used in order to assess the degree of disease awareness. However, as yet little research of this type has focused on multiple sclerosis (MS).

Method:

We here focused on an investigation of item-by-item metacognitive predictions (using feeling-of-knowing judgements) in episodic and semantic memory and global metacognitive predictions in standard neuropsychological tests pertinent to MS (processing speed and verbal fluency). Twenty-seven relapsing–remitting MS (RR-MS) patients and 27 comparison participants took part.

Results:

We found that RR-MS patients were as accurate as the group of comparison participants on our episodic and semantic item-by-item judgements. However, for the global predictions, we found that the MS group initially overestimated their performance (ds= .64), but only on a task on which performance was also impaired (ds= .89; processing speed). We suggest that MS patients, under certain conditions, show inaccurate metacognitive knowledge. However, postdictions and item-by-item predictions indicate that online metacognitive processes are no different from participants without MS.

Conclusion:

We conclude that there is no monitoring deficit in RR-MS and as such these patients should benefit from adaptive strategies and symptom education.
Consumer confusion about wholegrain content and healthfulness in product labels: a discrete choice experiment and comprehension assessment
Authors: Wilde Parke , Pomeranz Jennifer L , Lizewski Lauren J , Zhang Fang Fang
Published: August 2020

Objective:

Using a legal standard for scrutinising the regulation of food label claims, this study assessed whether consumers are misled about wholegrain (WG) content and product healthfulness based on common product labels.

Design:

First, a discrete choice experiment used pairs of hypothetical products with different amounts of WG, sugar and salt to measure effects on assessment of healthfulness; and second, a WG content comprehension assessment used actual product labels to assess respondent understanding.

Setting:

Online national panel survey.

Participants:

For a representative sample of US adults (n 1030), survey responses were collected in 2018 and analysed in 2019.

Results:

First, 29–47 % of respondents incorrectly identified the healthier product from paired options, and respondents who self-identified as having difficulty in understanding labels were more likely to err. Second, for actual products composed primarily of refined grains, 43–51 % of respondents overstated the WG content, whereas for one product composed primarily of WG, 17 % of respondents understated the WG content.

Conclusions:

The frequency of consumer misunderstanding of grain product labels was high in both study components. Potential policies to address consumer confusion include requiring disclosure of WG content as a percentage of total grain content or requiring disclosure of the grams of WG v. refined grains per serving.
Maternal perspectives on infant feeding practices in Soweto, South Africa
Authors: Wrottesley Stephanie V , Prioreschi Alessandra , Slemming Wiedaad , Cohen Emmanuel , Dennis Cindy-Lee , Norris Shane A
Published: August 2020

Objective:

To (i) describe the infant feeding practices of South African women living in Soweto and (ii) understand from the mothers’ perspective what influences feeding practices.

Design:

Semi-structured focus group discussions (FGD) and in-depth interviews (IDI) were conducted, and data were analysed using thematic analysis.

Setting:

Soweto, South Africa.

Participants:

Nineteen mothers were stratified into three FGD according to their baby’s age as follows: 0–6-month-olds, 7–14-month-olds and 15–24-month-olds. Four mothers from each FGD then attended an IDI.

Results:

Although mothers understood that breast-feeding was beneficial, they reported short durations of exclusive breast-feeding. The diversity and quality of weaning foods were low, and ‘junk’ food items were commonly given. Infants were fed using bottles or spoons and feeding commonly occurred separately to family meal times. Feeding practices were influenced by mothers’ beliefs that what babies eat is important for their health and that an unwillingness to eat is a sign of ill health. As such, mothers often force-fed their babies. In addition, mothers believed that feeding solid food to babies before 6 months of age was necessary. Family matriarchs were highly influential to mothers’ feeding practices; however, their advice often contradicted that of health professionals.

Conclusions:

In South Africa, interventions aimed at establishing healthier appetites and eating behaviours in early life should focus on: (i) fostering maternal self-efficacy around exclusive breast-feeding; (ii) challenging mixed feeding practices and encouraging more responsive feeding approaches and (iii) engaging family members to promote supportive household and community structures around infant feeding.
Does Item Difficulty Affect the Magnitude of the Retrieval Practice Effect? An Evaluation of the Retrieval Effort Hypothesis
Authors: Lima Marcos Felipe Rodrigues de , Venâncio Sebastião , Feminella Júlia , Buratto Luciano Grüdtner
Published: August 2020

Retrieving information by testing improves subsequent retention more than restudy, a phenomenon known as theretrieval practice effect.According to theretrieval effort hypothesis(REH), difficult items require more retrieval effort than easier items and, consequently, should benefit more from retrieval practice. In two experiments, we tested this prediction. Participants learned sets of easy and difficult Swahili–Portuguese word pairs (study phase) and repeatedly restudied half of these items and repeatedly retrieval practiced the other half (practice phase). Forty-eight hours later, they took a cued-recall test (final test phase). In both experiments, we replicated both the retrieval practice and the item difficulty effects. In Experiment 1 (N= 51), we found a greater retrieval practice effect for easy items,MDifference= .26,SD= .17, than for difficult items,MDifference= .19,SD= .19,t(50) = 2.01,p= .05,d= 0.28. In Experiment 2 (N= 28), we found a nonsignificant trend—F(1, 27) = 2.86,p= .10,$$ {\upeta}_{\mathrm{p}}^2 $$= .10—toward a greater retrieval practice effect for difficult items,MDifference= .28,SD= .22, than for easy items,MDifference= .18,SD= .21. This was especially true for individuals who benefit from retrieval practice (difficult:MDifference= .32,SD= .18; easy:MDifference= .20,SD= .20),t(24) = –2.08,p= .05,d= –0.42. The results provide no clear evidence for the REH and are discussed in relation to current accounts of the retrieval practice effect.
Patriotism without Patriots? Perm΄-36 and Patriotic Legitimation in Russia
Authors: Goode J. Paul
Published: August 2020

This article examines the takeover of the Perm’-36 Gulag museum as emblematic of the dynamics of patriotic legitimation in Russia. The museum was dedicated to preserving the memory of the victims of Soviet political repression and it grew in popularity into the 2000s, emerging as an opposition platform and target for self-styled patriots who accused it of distorting Soviet history. The regional government soon joined the battle, finally forcing the museum's takeover and transforming it into a site honoring the Gulag rather than its victims. Drawing on interviews conducted with the museum's former director and scientific directors in 2015 and extensive local press materials, this analysis of the struggle over Perm’-36 demonstrates the significance of patriotism in sustaining the regional government's attacks even in the absence of federal patronage. The findings thus challenge prevailing understandings of authoritarian regime politics as driven primarily by patronage and power-maximizing elites.

We examined the item properties of the Two Peas Questionnaire (TPQ) among a sample of same-sex twin pairs from the Washington State Twin Registry. With the exception of the ‘two peas’ item, three of the mistakenness items showed differential item functioning. Results showed that the monozygotic (MZ) and dizygotic (DZ) pairs may differ in their responses on these items, even among those with similar latent traits of similarity and confusability. Upon comparing three classification methods to determine the zygosity of same-sex twins, the overall classification accuracy rate was over 90% using the unit-weighted pair zygosity sum score, providing an efficient and sufficiently accurate zygosity classification. Given the inherent nature of twin-pair similarity, the TPQ is more accurate in the identification of MZ than DZ pairs. We conclude that the TPQ is a generally accurate, but by no means infallible, method of determining zygosity in twins who have not been genotyped.
Women Want an Answer! Field Experiments on Elected Officials and Gender Bias
Authors: Magni Gabriele , Ponce de Leon Zoila

Are elected officials more responsive to men than women inquiring about access to government services? Women face discrimination in many realms of politics, but evidence is limited on whether such discrimination extends to interactions between women and elected officials. In recent years, several field experiments have examined public officials’ responsiveness. The majority focused on racial bias in the USA, while the few experiments outside the USA were usually single-country studies. We explore gender bias with the first large-scale audit experiment in five countries in Europe (France, Germany, Ireland, Italy, and Netherlands) and six in Latin America (Argentina, Brazil, Chile, Colombia, Mexico, and Uruguay). A citizen alias whose gender is randomized contacts members of parliament about unemployment benefits or healthcare services. The results are surprising. Legislators respond significantly more to women (+3% points), especially in Europe (+4.3% points). In Europe, female legislators in particular reply substantially more to women (+8.4% points).
Diagnostik und Therapie der Adnexitis (Pelvic Inflammatory Disease)
Authors: Siegenthaler Franziska , Krause Elke , Mueller Michael D.

Zusammenfassung. Die Adnexitis, im anglo-amerikanischen Sprachgebrauch hat sich der Sammelbegriff Pelvic Inflammatory Disease (PID) durchgesetzt, stellt ein häufiges medizinisches Problem dar. Die Diagnose einer PID kann schwierig sein, da die klinischen Manifestationen unspezifisch sind und sie andere Becken- und Bauchprozesse imitieren können. Infektionen im Bereich der Adnexen können schwerwiegend sein und Langzeitkomplikationen (chronische Unterbauchschmerzen, Infertilität) verursachen, weshalb eine rasche Diagnosestellung und der frühzeitige Beginn einer adäquaten Antibiotika Therapie von grosser Wichtigkeit sind. Unkomplizierte PID haben meistens einen günstigen Verlauf, bei komplizierten Formen mit Tuboovarialabzess ist meist eine operative Exploration notwendig.

Transit time distributions (TTDs) exert important controls on biogeochemical processes in watershed systems. TTDs are often assumed to follow time‐invariant exponential, lognormal, or heavy‐tailed power law distributions in headwater or low‐order streams. However, under dynamic hydrological forcing, transit time could exhibit more complex distribution patterns with strong spatial and temporal variability. In this study, we used a numerical particle tracking approach to characterize TTDs along the Hanford Reach of the Columbia River under the influences of river stage fluctuations and evaluate the associated effects on biogeochemical reaction potentials within the river corridor. Particle tracking was conducted using velocity fields simulated by high‐resolution three‐dimensional groundwater flow models that capture both the river stage fluctuations and physical heterogeneity. Our results revealed that multifrequency flow variations led to multimodal TTDs that varied in time and space. Such characteristics can only be captured by multiyear numerical simulations supported by multiyear field monitoring. Dam‐induced high‐frequency (subweekly) flow variations increased additional hydrologic exchange flows with short (subweekly) transit times, which accounted for up to 44% of reactant consumption in the river corridor along the Hanford Reach. The dam‐induced river stage fluctuations have more significant impacts on faster biogeochemical reactions because they cause a larger fraction of shorter transit times. Numerical particle tracking provides an efficient alternative for characterizing TTDs for large complex systems where in situ field experiments are not feasible. Such a numerical approach is thus essential for improving large‐scale biogeochemical modeling from watersheds to basins.
Future Warming and Intensification of Precipitation Extremes: A “Double Whammy” Leading to Increasing Flood Risk in California
Authors: Huang Xingying , Stevenson Samantha , Hall Alex D.
Published: August 2020

This study focuses on quantifying future anthropogenic changes in surface runoff associated with extreme precipitation in California's Sierra Nevada. The method involves driving a land surface model with output from a high resolution regional atmospheric simulation of the most extreme atmospheric rivers (ARs). AR events were selected from an ensemble of global climate model simulations of historical and late 21st century climate under the “high‐emission” RCP8.5 scenario. Average precipitation during the future ARs increases by ~25% but a much lower proportion falls as snow. The resulting future runoff increase is dramatic—nearly 50%, reflecting both the precipitation increase and simultaneous conversion of snow to rain. The “double whammy” impact on runoff is largest in the 2,000–2,500 m elevation band, where the snowfall loss and precipitation increase are both especially large. This huge increase in runoff during the most extreme AR events could present major flood control challenges for the region.

The Parker Solar Probe successfully makes electric field measurements over the frequency range of DC‐100 Hz, thanks to the remarkable symmetry of the antennas with respect to sunlight and the mostly radial magnetic field. Calibration of the electric field measurement is described. Sampled electric and magnetic field data are utilized to determine wave modes of whistlers and Alfven‐ion‐cyclotron waves. In the course of such determinations, the electric field effective antenna length was found to vary with frequency from ~1 m at low frequencies to essentially the antenna half‐geometric length of 3.5 m above 20 Hz. Properties of the low‐frequency electric field power as functions of frequency and radial distance are determined. There is a plateau in the electric field power spectrum above ~10 Hz, which is due to the power in waves exceeding the turbulent cascade power above that frequency. This wave power decreases by one to two orders of magnitude from 35 to 50 solar radii.

The floating ice tongue of 79 North Glacier, a major outlet glacier of the Northeast Greenland Ice Stream, has thinned by 30% since 1999. Earlier studies have indicated that long‐term warming of Atlantic Intermediate Water (AIW) is likely driving increased basal melt, causing the observed thinning. Still, limited ocean measurements in 79 North Fjord beneath the ice tongue have made it difficult to test this hypothesis. Here we use data from an Ice Tethered Mooring (ITM) deployed in a rift in the ice tongue from August 2016 to July 2017 to show that the subannual AIW temperature variability is smaller than the observed interannual variability, supporting the conclusion that AIW has warmed over the period of ice tongue thinning. In July 2017, the AIW at 500 m depth in the ice tongue cavity reached a maximum recorded temperature of 1.5°C. Velocity measurements reveal weak tides and a mean overturning circulation, which is likely seasonally enhanced by subglacial runoff discharged at the grounding line. Deep inflow of AIW and shallow export of melt‐modified water persist throughout the record, indicating year‐round basal melting of the ice tongue. Comparison with a mooring outside of the cavity suggests a rapid exchange between the cavity and continental shelf. Warming observed during 2016–2017 is estimated to drive a 33 ± 20% increase in basal melt rate near the ice tongue terminus and a 14 ± 2% increase near the grounding line if sustained.
A Breakdown in Potential Vorticity Estimation Delineates the Submesoscale‐to‐Turbulence Boundary in Large Eddy Simulations
Authors: Bodner Abigail S. , Fox‐Kemper Baylor
Published: August 2020

Most submesoscale motions—fronts, eddies, filaments, and even large internal waves—are sufficiently rapidly rotating and stratified as to be strongly influenced by potential vorticity dynamics. Below the Ozmidov scale where turbulence overturns and isotropizes, potential vorticity is not commonly considered. Here, it is shown that in Large Eddy Simulations, the velocity gradients, buoyancy gradients, and potential vorticity are strongly influenced by grid‐scale processes. Grid‐scale processes in Large Eddy Simulations, as opposed to those in Direct Numerical Simulations, imply that spuriously noisy potential vorticity variance will become increasingly dominant as resolution increases—analogous to ultraviolet catastrophe. A solution, the prefiltered potential vorticity, is shown to be effective in linking the potential vorticity dynamics of the submesoscale to the nearly‐isotropic turbulent fluxes beyond the Ozmidov scale, and a derivation is provided for a set of closed conservation equations for use in interpreting potential vorticity dynamics in Large Eddy Simulations. This diagnostic approach is exceptional in that Large Eddy Simulation analysis and hydrostatic ocean modeling with parameterized turbulence analysis are harmonized.
