Background

Explosive outbursts occur in 25%–70% of children with Tourette syndrome (TS) and may cause more distress than the tics themselves. Previous studies have indicated that a comorbid diagnosis of attention‐deficit/hyperactivity disorder (ADHD) is associated with emotional dysregulation in TS; however, this relationship has almost exclusively been studied using parent‐reported questionnaires.

Methods

We examined emotion regulation (ER) with an observational measure in 150 medication‐naïve children aged 7–12 allocated to four groups: Forty‐nine children with TS, 23 children with ADHD, 16 children with TS + ADHD, and 62 typically developing controls. We assessed participants’ ER ability, as well as parent–child interactions in the context of a complex puzzle task, and coded the observed behavior with the Tangram Emotion Coding Manual (TEC‐M). We examined group differences in ER, as well as associations between ER and severity of symptoms pertaining to TS and ADHD.

Results

Children with TS did not differ from controls in their ER ability. However, children with ADHD and TS + ADHD had more problems with ER than those with TS only and controls. Finally, parents of children with ADHD displayed more tension during the experimental task. ER ability was not associated with tic severity nor premonitory urges; however, better ER ability was associated with less severe symptoms of ADHD.

Conclusions

This study is the first to evaluate ER with an observational, clinician‐rated measure in a controlled social setting in children with TS. Our findings support earlier questionnaire‐based studies by showing impaired ER in children with TS + ADHD, but not in children with TS without comorbidity. These findings inform our understanding of the phenomenology of emotional dysregulation in TS and the role of comorbid disorders.
Sharing the value‐at‐risk under distributional ambiguity
Authors: Chen Zhi , Xie Weijun
Published: December 2020

This paper considers the problem of risk sharing, where a coalition of homogeneous agents, each bearing a random cost, aggregates their costs, and shares the value‐at‐risk of such a risky position. Due to limited distributional information in practice, the joint distribution of agents' random costs is difficult to acquire. The coalition, being aware of the distributional ambiguity, thus evaluates the worst‐case value‐at‐risk within a commonly agreed ambiguity set of the possible joint distributions. Through the lens of cooperative game theory, we show that this coalitional worst‐case value‐at‐risk is subadditive for the popular ambiguity sets in the distributionally robust optimization literature that are based on (i) convex moments or (ii) Wasserstein distance to some reference distributions. In addition, we propose easy‐to‐compute core allocation schemes to share the worst‐case value‐at‐risk. Our results can be readily extended to sharing the worst‐case conditional value‐at‐risk under distributional ambiguity.
Do positive interactions between marine invaders increase likelihood of invasion into natural and artificial habitats?
Authors: Firth Louise B. , Duff Lois , Gribben Paul E. , Knights Antony M.
Published: December 2020

Positive species interactions such as facilitation are important for enabling species to persist, especially in stressful conditions, and the nature and strength of facilitation varies along physical and biological gradients. Expansion of coastal infrastructure is creating hotspots of invasive species which can spillover into natural habitats, but the role of positive species interactions associated with biological invasions remains understudied. Theory suggests that stronger biotic pressure in natural habitats inhibits invasion success. In space‐limited marine systems, sessile organisms can overcome this limiting resource by settling as an epibiont on a substrate organism – basibiont. Using a series of spatially extensive surveys, we explored the role of invasive and native basibionts in providing habitat for other invasive and native epibionts, and tested whether environmental context (i.e. if the receiving habitat was natural or artificial), altered ecological outcomes. Overall, provision of space by basibionts was more important for invasive epibionts than for native epibionts but was dependent on the environmental context. Invasive basibionts facilitated invasive epibionts in natural habitats, and appeared to be more important for native epibionts in artificial habitats respectively. Native basibionts facilitated invasive, but not native epibionts in both natural and artificial habitats. These results advance our understanding of facilitation and highlight the idiosyncratic nature of biofouling and epibiosis, and the potentially important influence of environmental context. The degree to which native habitat‐forming species versus invasive habitat‐forming species either do or do not facilitate other native or non‐native species is a rich area for investigation. Experimental work is required to disentangle the processes underpinning these patterns.
The Effect of Administrative Burden on Farmers’ Perceptions of Cross‐Compliance‐Based Direct Payment Policy
Authors: Mack Gabriele , Ritzel Christian , Heitkämper Katja , El Benni Nadja
Published: December 2020

In this study, we test the hypothesis that farmers’ experienced administrative burden affects their policy perceptions. Based on survey data from 808 randomly chosen Swiss farmers, a latent class approach is used to depict the heterogeneity of farmers' policy perceptions. We find that 20 percent of farmers are grumpy with the current direct payment policy, 23 percent are supporters, and 57 percent are indifferent, meaning that the latter group of farmers neither agree nor disagree with the direct payment policy. Regression results indicate that the higher the perceived administrative burden, the higher the probability of belonging to the grumpy class of farmers. Additionally, our results show that grumpy farmers have less social exchange than their peers and exhibit lower environmental awareness. Our findings show that the bureaucracy involved in agricultural policy matters not only because it increases private and public administrative costs but also because it negatively shapes farmers' view of agricultural policy.
Diversifying the bench: Applying social cognitive theories to enhance judicial diversity
Authors: Carroll Ellen M. , Walker Tammi D. , Croft Alyssa
Published: December 2020

White men remain overrepresented in the American judiciary (i.e., the bench) despite increasing demographic diversity among law students and lawyers. Augmenting efforts to tackle systemic barriers, a social cognitive process model integrating Goal Congruity and Cultural Mismatch Theories to partially explain why women, first‐generation, and underrepresented racial minority (URM) lawyers are less likely to pursue and thrive in judicial roles was proposed. The unexplored misalignment between the goals and values typically endorsed by eligible underrepresented judicial candidates and their perceptions of judgeship was addressed. Specifically, women, first‐generation, and URMs tend to endorse primarily communal/interdependent goals and values, while judgeship is viewed as a stereotypically agentic/independent profession. Thus, judicial diversity could be enhanced by (1) highlighting role attributes that are aligned with communal/interdependent values and (2) increasing appreciation for existing judicial communality/interdependence. It was concluded by providing hypothesized interventions to target key psychological mechanisms along the “leaky pipeline” to the judiciary.

Topology Optimization of Interactive Visual Communication Networks Based on the Non-Line-of-Sight Congestion Control Algorithm
Authors: Liu Boya , Zhou Xiaobo
Published: December 2020

In this paper, an in-depth study of interactive visual communication of network topology through non-line-of-sight congestion control algorithms is conducted to address the real-time routing problem of adapting to dynamic topologies, and a delay-constrained stochastic routing algorithm is proposed to enable packets to reach GB within the delay threshold in the absence of end-to-end delay information while improving network throughput and reducing network resource consumption. The algorithm requires each sending node to select an available relay set based on the location of its neighbor nodes and channel state and computes transfer probabilities for each node in the relay set combining the remaining delay of the packet with the distance from the relay node to GB. Based on the obtained transfer probability and local channel state, the sending node passes the packet to the relay node. The convergence of the algorithm is proved and its performance is verified by simulation. The first part of the algorithm is based on the greedy algorithm to deploy and locate the network flying platform nodes with the goal of efficient coverage of the network flying platform nodes, considering the ground base station services. As the delay on each link varies due to the change of channel state, the source and relay nodes asynchronously update the data generation rate and the pairwise parameters based on the received local information and use the obtained optimal values to pass the packets to GB.
B7‐H3‐Induced Signaling in Lung Adenocarcinoma Cell Lines with Divergent Epidermal Growth Factor Receptor Mutation Patterns
Authors: Ding Meng , Liao Haixiu , Zhou Nannan , Yang Ying , Guan Shihe , Chen Liwen
Published: December 2020

The cosignal molecule B7‐H3 is gaining attention due to its abnormal expression and abundant signal transduction in many types of malignancies. B7‐H3‐induced signaling includes at least three cascades: PI3K/AKT, JAK2/STAT3, and Raf/MEK/ERK1/2, which are also involved in epidermal growth factor receptor‐ (EGFR‐) triggered signaling in lung adenocarcinoma cells. However, the correlation between B7‐H3‐induced signaling and EGFR signaling, and between B7‐H3‐targeted immunotherapy and EGFR‐targeted therapy in lung adenocarcinoma, remains to be elucidated. Herein we find that knockout of B7-H3 gene decreased cell survival and increased EGFR‐tyrosine kinase inhibitor gefitinib susceptibility of both H3255 and HCC827 cells, two lung adenocarcinoma cell lines harboring EGFR L858R (exon 21) and Del E746‐A750 (exon 19) mutations, respectively. B7-H3 deletion resulted in dramatic reduction of phosphorylation level of AKT and STAT3 in H3255 cells while having mild‐to‐moderate suppression on AKT, STAT3, and ERK1/2 in HCC827 cells. Gefitinib had similar effects with B7-H3 deletion both in H3255 and HCC827 cells. Furthermore, B7-H3 ablation had significant synergistic effects with gefitinib in HCC827 cells. Collectively, our study reveals B7‐H3‐induced signaling in lung adenocarcinoma cell lines with divergent EGFR mutations, and a translational potential of combined targeted therapy of B7‐H3 and EGFR in lung adenocarcinoma with EGFR Del E746‐A750 mutation.
Diurnal Variation of Seasonal Precipitation over the CONUS: A Comparison of Gauge Observations with TRMM Data
Authors: Zhu Liming , Zhao Yu , Rui Xiaoping , Wei Qingwei
Published: December 2020

Diurnal variation of precipitation is a fundamental periodic signal of local climate. Comprehensive study of diurnal variation of precipitation is helpful in studying the formation of local climate and validating satellite precipitation products. In this study, a comparison is drawn between precipitation gauge observations and Tropical Rainfall Measuring Mission (TRMM) 3B42 data on diurnal variation of precipitation. First, using the K-means clustering algorithm, stations with gauge observations and pixels with TRMM data are divided into different groups according to the diurnal variation of precipitation, respectively. In each group, the stations have similar diurnal variation of precipitation. Then maps of diurnal variation of precipitation for gauge observations and TRMM data are obtained. According to these maps, the diurnal variation of precipitation over the contiguous United States (CONUS) presents seasonal variability in both gauge observations and TRMM data. In addition, the diurnal variation of precipitation shows clustered features in space. However, the spatial patterns of the obtained maps do not match, and the TRMM satellite data perform poorly in capturing the hourly precipitation event. Finally, the possible mechanism behind the prevailing nocturnal precipitation over the middle of the CONUS is discussed, with the prevailing nocturnal precipitation judged likely to be strongly related to the mountain-plains solenoid (MPS) circulation.
Ritual Purity in Daily Life after 70 CE: The Chalk Vessel Assemblage from Shuʿafat as a Test Case
Authors: Adler Yonatan
Published: December 2020

Chalk vessels became common at Jewish sites throughout the Southern Levant beginning in the late first century BCE, apparently because Jews considered stone to be impervious to ritual impurity. It is commonly thought that a drastic decline in the phenomenon occurred after 70 CE as a direct result of the temple’s destruction—on the assumption that the central motivation for Jews’ observance of the purity regulations was the temple cult. These notions are reconsidered here in light of an impressive assemblage of chalk vessels recently unearthed at Shuʿafat, occupied during the brief 70–132 CE interwar period. The character of this assemblage, presented here preliminarily, suggests that both use and production of chalk vessels continued unabated for decades after 70 CE, contradicting the notion that the chalk vessel industry was reliant on a functioning temple and that observance of the purity laws was inexorably linked with the Jerusalem cult.

Research progress on the prediction of post-stroke epilepsy
Authors: Zou Shangnan , Chen Yangmei
Published: December 2020

Epilepsy is a common neurological disease that not only causes difficulties in the work and life activities of patients, but also brings complex social problems. Cerebrovascular disease is currently the main cause of epilepsy in the elderly. With the increased survival rate of patients after stroke, the incidence of epilepsy after stroke has also increased. Effective prediction of epilepsy after stroke is extremely crucial for the prognosis of patients, the initiation of antiepileptic therapy and the reduction of epileptic seizures. In this review, we summarize and compare the current models for the prediction of epilepsy after stroke, including the SeLECT prediction model, Post-Stroke Epilepsy Risk Scale (PoSERS), CAVE score, electroencephalogram (EEG) prediction model, and Scandinavian Stroke Scale (SSS) score, in order to provide reference for clinical practice and future research. Prediction models can be selected based on the clinical classification of cerebrovascular events. The SeLECT score prognostic model is a better choice for ischemic stroke, especially for the exclusive prediction of mild post stroke epilepsy. The CAVE score model is suitable for intra-cerebral hemorrhage patients. It is simple and offers high correlation between the risk factors and epilepsy. The PoSERS score simultaneously predicts ischemic and hemorrhagic stroke, and is superior to other methods in specificity as well as positive and negative prediction rate. The SSS score, which only measures stroke severity, is not strictly considered as a mature predictor, but it can be used as a first step screening tool. A growing number of large studies are under the way to identify risk factors of poststroke epilepsy (PSE) and to improve the inclusion of predictive indicators. New and advanced findings by EEG recordings may further improve the prediction of PSE.

Published: December 2020

Hierarchical spinel NiCo2O4 microflowers have been successfully designed and synthesized by a successive mild spray-thermal treatment method via bimetallic NiCo-metal-organic framework formation. Remarkably, NiCo2O4 microflowers can serve as a novel and efficient electrocatalytic active material, showing excellent performance for a non-enzymatic glucose sensor. The obtained NiCo2O4 flower-like structure is composed of two-dimensional nanosheets, and the nanosheet surface is fully exposed to facilitate the diffusion of electrolyte. In the glucose sensing system, the NiCo2O4 microflower-modified glassy carbon electrode exhibits a wide detection range from 0.001 mM to 7.8 mM, a low detection limit of 0.48 µM and a fast response time (3 s). Furthermore, the non-enzymatic glucose sensor shows a considerable anti-interference ability and long-term stability. This work opens up an avenue for the synthesis of hierarchical bimetallic microflower material by a mild spray-thermal treatment method, which also provides a promising strategy for the real-time glucose sensing.

Türkiye’de 1960’lı yılların sonları; büyük öğrenci hareketlerinin başlayıp yayıldığı, ülke gündemini uzun süre meşgul eden dönem olmuştur. Türkiye’de köyden kente göç ile birlikte sosyal hareketliliğin ve kültür değişimlerin/çatışmaların arttığı bu dönemde üniversite ve öğrenci sayıları da hızla artmıştır. Bu artış oranına paralel bir şekilde eğitim öğretim altyapı gelişmemişti. Büyük umutlarla yükseköğretime başlayan gençlerin bir kısmı; okulların fiziksel yetersizlikleri, araç-gereç ve ders kaynağı eksikliği, kredi yetersizliği, ekonomik sıkıntılar ve gelecek kaygıları nedeniyle çeşitli çözüm arayışı içerisine girmişlerdir. Eğitim şartlarının yeniden düzenlenmesi amacıyla yola çıkan gençler, mevcut olumsuz şartların bir türlü değişmemesi nedeniyle ülke yönetimini sorgulamaya başlamışlardır. Bu dönemde çeşitli ideolojik sol akımların da etkisiyle giderek marjinalleşmeye ve şiddete yönelmeye başladılar. Başlangıç dönemindeki eğitimde reform ve şartlarının düzeltilmesi taleplerinin yerine, zamanla ideolojik örgütlerin de yönlendirmesiyle zor kullanarak ülke siyasal rejimini değiştirmeye yöneldiler.

Bu yüzden bugünün olabileceği gibi geleceğin de mükellefleri olabilecek öğrenciler için çalışmalar yapılması önem arz etmektedir. Öğrencilerin mali bilinçlerinin geliştirilmesi için kamu harcaması bilinçlerinin de geliştirilmesi gerekmektedir. Buna göre bu çalışmanın amacı öğrencilerin kamu harcaması bilinçlerinin tespit edilmesi ve geliştirilmesidir. Bu bağlamda öğrencilere açık uçlu soru yöneltilmiştir. Daha sonra öğrencilerin kamu harcaması bilinçlerini geliştiren bir deney yapılmıştır. Deney sonrasında öğrencilere açık uçlu soru tekrar yöneltilmiş ve kamu harcaması bilinçleri tespit edilmiştir. Deney öncesinde öğrencilerin kamu harcaması bilinçlerinin çok düşük olduğu, sonrasında öğrencilerin kamu harcaması bilinçlerinin yüksek olduğu ve böylelikle geliştirilebildiği tespit edilmiştir. Bu çalışmada elde edilen bulgularla gelecek çalışmalarda kullanılmak üzere öğrencilerin kamu harcaması bilinçlerini tespit eden Likert ölçekli bir soru geliştirilmiştir.

Published: December 2020

Civil Aviation Industry has entered into a great development trend, especially since the 1978 deregulation period. Strategies implemented by airlines are of great importance in this development trend. Although airline partnerships cause airlines to lose their brand values, more successes are achieved under operational and financial criteria. For this reason, airline partnerships have been a strategy used by both large and small scale airlines in European aviation for the last 10 years. When it is examined the 10 biggest airlines of Europe excluding low-cost carriers, it is seen that only Turkish Airlines have not in a partnership. The aim of this study is to analyze the impact of partnerships established on the airlines' operational and financial efficiency. While the number of revenue passengers and the total number of landings are operational inputs, the available seat kilometer and revenue passenger kilometer are financial outputs. While the results obtained from these data help to determine how efficient the biggest airlines in Europe are, on the other hand, it expresses how important it is in its different criteria.

Türkiye’de 1980’ler sonrası ortaya çıkan kentsel dönüşüm uygulamaları ilk zamanlar çöküntü alanlarına yönelik fiziki müdahale olarak algılanmıştır. Günümüzde bu algı değişmiş ve kentsel dönüşüm, ekonomik, sosyal ve mekânsal boyutuyla da incelenmesi gereken bir kentsel planlama aracı olarak ele alınmaya başlanmıştır. Türk hukukunda kentsel dönüşüm uygulamalarını düzenleyen tek bir kanun bulunmamakla birlikte, kentsel dönüşüm sürecinde yararlanılan, iş bölümünü düzenleyen, idareler ve mal sahipleri arasında koordinasyonu sağlayan, kamulaştırma sürecini içeren farklı kanunlardan yararlanıldığı bilinmektedir. Kentsel dönüşümün mevzuat kapsamının geniş olmasına rağmen, düzenlemeler arası farklılıkların olduğu sıklıkla tartışma konusu yapılmaktadır. Kentsel dönüşüm sürecinde hak sahipleri ile idareler arasında ortaya çıkan hukuki uyuşmazlıkların çoğunlukla kamulaştırma, değerleme ve planlama sürecine ilişkin olduğu tespit edilmiştir. Araştırmada incelenen mahkeme kararlarında, kamulaştırma işlemlerinin ve kentsel alana yönelik planlamanın yasal mevzuata uygun yürütülmesi ve mülkiyet hakkının korunması ön plana çıkarılmıştır.

Authors:   St. Petersburg Mining University, Tsiglianu P.
Published: December 2020

The oil fields development design presumes the availability of sufficient geological information about its accumulations. The time being Russian Federation there are no yet any institutionalized geological assessment targets of oil discovery, which will provide an optimal level of geological assessment of an oil field for the entire period of its development (including the stages of exploration and exploitation). The problem of the standardization of geological assessment level of oil accumulations is often brought up by petroleum engineers and some steps in this direction were made by a group of soviet geologists headed by A. Fursov and at the present time by A. Yanin. Basing on the actuality of this topic and accomplished research, the problem of justification of an optimal geological assessment level of oil accumulations in the process of oil fields development designing, especially of small and very small ones is studied in this article. As well, the geological assessment targets for evolved oil accumulations are suggested.

Programs and technologies for the prevention of social risks in the education system are concidered from the standpoint of an evidence-based approach. The article presents the results of approbation and analysis of the «Skillful class»-method effectiveness. This is a Russian adaptation of the Finnish Skilful Class solution-oriented program, which implements a creative and positive approach to teaching children with emotional and behavioral difficulties in the class / group. It was based on the Kids' Skills method of Ben Furman, his 15-step-program for developing children social skills. The technology has been tested at more than 20 regions platforms. Statistically significant indicators of the formation and dynamics of skills mastered by children were termed as well as other parameters that are significant for reducing risk factors of the deviant behavior. This method can serve as a tool for early prevention of social risks that appear in preschool and primary school age (school maladaptation, emotional and behavioral problems, deviations, ostracism, school bullying, conflicts).
