Authors: Badr Elsayed Metwalli , Elgendy Horia
Published: May 2020

Groundwater sustainability is the development and use of groundwater resources to meet current and future beneficial uses without causing unacceptable environmental or socioeconomic consequences. This study is the first time to apply the hybrid optimization technique for solving of managing underground water aquifers, the confined steady flow problems, where a hybrid water cycle - particle swarm optimization WCA-PSO is proposed. In particular, we introduce a novel hybrid algorithm using water cycle algorithm (WCA) and particle swarm Optimization (PSO). The performance of the novel hybrid algorithm WCA-PSO is evaluated to solve 10 benchmark problems chosen from literature. The simulation results and comparison with pure WCA and PSO algorithms confirm the effectiveness of the proposed algorithm WCA-PSO for solving various benchmark optimization functions. Finally, we solve the problem of managing underground water aquifers by WCA, PSO and the hybrid optimization WCA-PSO. The experimental results analysis and statistical tests prove that the hybrid algorithm WCA-PSO overcomes the pure algorithms.

Published: May 2020

The congestion of road traffic is one of the most problems facing the ambulance transportation to provide fast healthcare service for patient. In this work, ambulance tracking with messages transfer system has been designed and implemented such that a central monitoring and tracking unit can observe ambulance using MQTT IoT protocol. Where each vehicle is occupied with an intelligent embedded system (Raspberry Pi) unit. When an ambulance is being in the road, it will communicate with other vehicle or road traffic by means of CoAP IoT protocol as a direct device to device communication. The proposed system has been designed such that driver use voice chat and the system are completely hand free. The voice message is being transfer into text by using speech recognition based Google API library, and then the received text message is converted again to speech by using text to speech algorithm. An encryption–decryption process-based stream cipher has been used. The message between IoT nodes has been encrypted using One Time Pad (OTP) and DNA computing. Furthermore, the required key sequence was generated using a linear feedback shift register (LFSR) as a pseudo number key generator. This key sequence was combined to generate a unique key for each message.

Published: May 2020

The fast development of mobile apps and its usage has led to increase the risk of exploiting user privacy. One method used in Android security mechanism is permission control that restricts the access of apps to core facilities of devices. However, that permissions could be exploited by attackers when granting certain combinations of permissions. So, the aim of this paper is to explore the pattern of malware apps based on analyzing permissions by proposing framework utilizing feature selection based on ensemble extra tree classifier method and machine learning classifier. The used dataset had 25458 samples (8643 malware apps & 16815 benign apps) with 173 features. Three dataset with 25458 samples and 5, 10 and 20 features respectively were generated after using the proposed feature selection method. All the dataset was fed to machine learning. Support Vector machine (SVM), K Neighbors Classifier, Decision Tree, Naïve bayes and Multilayer Perceptron (MLP) classifiers were used. The classifiers models were evaluated using true negative rate (TNR), false positive rate (FNR) and accuracy metrics. The experimental results obtained showed that Support Vector machine and KNeighbors Classifiers with 20 features achieved the highest accuracy with 94 % and TNR with rate of 89 % using KNeighbors Classifier. The FNR rate is dropped to 0.001 using 5 features with support vector machine (SVM) and Multilayer Perceptrons (MLP) classifiers. The result indicated that reducing permission features improved the performance of classification and reduced the computational overhead.

Comparison between amiodarone and lidocaine for ventricular fibrillation treatment during cardiopulmonary resuscitation
Authors: Shin Yoon Ji , Borges Victor André , Souza Heraldo Possolo de
Published: May 2020

Cardiac arrest is a condition in which the heart mechanical functioning is compromised and usually it is due an electrical dysfunction of the cardiac cells and this can result in disorganization of cardiac rhythm and even heart failure, a situation of medical emergency in which seconds can make the difference between life and death. In cardiac arrest, it’s necessary to perform cardiopulmonary resuscitation (CPR) maneuver and, if there are shockable rhythms (such as ventricular fibrillation and pulseless ventricular tachycardia), defibrillation should be administered on the patient. Even if the cardiac rhythm is reestablished, the condition is still serious due to the risk of recurrent electrical alteration of the heart. With the intent of avoiding a new rhythmic alteration of the heart, it’s ministered antiarrhythmic drugs, such as amiodarone or lidocaine. Eventhough the use of one of these drugs is recommended, there are no consensuses about which one has higher survival rate of patients or which has the highest rate of return of spontaneous circulation. Thus, this systematic review aims to clarify which one of these two drugs is more efficient at preventing new electrical alterations of patients post cardiorespiratory arrest.

A reanimação cardiopulmonar (RCP) precoce e eficaz realizada por espectadores é um preditor importante da sobrevida em vítimas de parada cardiorrespiratória fora de hospitais. Nesse sentido, a OMS preconiza o treinamento em RCP em escolas desde 12 anos. Este estudo objetiva avaliar a efetividade do treinamento de crianças em suporte básico de vida. Para isso, foi realizada uma revisão sistemática da literatura na base indexadora MedLine, com frase de pesquisa construída com as palavras “Cardiopulmonary Resuscitation” “Education” e “Child” e suas variações obtidas no MeSH. Foram critérios de inclusão estudos publicados em até cinco anos com abordagem do treinamento de RCP para crianças em ambiente escolar. Foram excluídos estudos de revisão sem descrição dos métodos de treinamento e com resultados incompletos. Foram selecionados 13 adequados aos métodos deste estudo. Em todos houve um treinamento teórico e prático seguidos da aplicação de um questionário avaliativo. Os resultados demonstram a inefetividade das compressões de crianças menores atribuída ao baixo peso, altura e IMC, e um maior interesse de crianças menores em relação às maiores e adultos. Treinamentos de RCP para crianças antes mesmo dos 12 anos são efetivos. Apesar da RCP ineficaz, o conhecimento adquirido propicia a solidificação das técnicas no futuro.

Study Design: Cross-sectional. Objective: Estimating the prevalence of hypovitaminosis D in a group of severely obese subjects referred to bariatric surgery. Methods: This study evaluated severely obese patients aged ≥18 years assisted by a specialized team in bariatric surgery. Clinical, anthropometric, and laboratory data were obtained from patient records. Plasma 25 (OH) D was determined by chemiluminescence and levels ≤ 20 ng/mL was considered as Hypovitaminosis D. The data were analyzed using the Statistical Package for Social Sciences® (SPSS) 20.0. Variables were described using descriptive statistics. For the comparison of the three groups, ANOVA, Kruskal-Wallis, and Pearson's chi-square tests were used. Spearman correlation test was performed to assess correlations between 25(OH)D and the other variables. P-values <0.05 were considered to be significant. Results: The study included 400 individuals, 71% were female with the mean age (SD) and BMI (SD) of 35.6 (9.1) years and 41.4 (5.1) kg/m², respectively. The vitamin D ranged from 4.5 to 62.4 ng/mL and the mean (SD) was 24.7 (7.9) ng/mL. In this sample, 117 (29.3%) individuals had hypovitaminosis D. There was a negative correlation between 25(OH)D and BMI (r= -0.110; p=0.028) and parathormone (r= -0.152; p=0.006) and positive correlation with serum calcium (r= 0.132; p=0.013) and phosphorus (r= 0.116; p=0.027). Conclusion: Severely obese subjects had a high prevalence of hypovitaminosis D even living in a sunny state.

Published: May 2020

Usualmente colocadas em oposição ao território, as redes digitais que conformam o ciberespaço são analisadas neste artigo a partir de sua ancoragem espacial. A territorialidade do ciberespaço é aqui restituída em sua relação com o espaço jurisdicional dos Estados nacionais, como um objeto técnico com características espaciais concomitantemente opostas e complementares, produzindo dinâmicas transfronteiriças ao mesmo passo em que se nacionaliza dentro dos limites westfalianos. Investigamos essa oposição complementar com base em casos concretos que nos permitem verificar o movimento do ciberespaço não apenas como gerador de dinâmicas transnacionais, mas como um espaço que permite o exercício de uma multiterritorialidade jurisdicional, com a qual determinados Estados atuam extraterritorialmente, normatizando outras soberanias. Com alicerce em tal exploração, examinamos as implicações das redes digitais sobre as configurações territoriais westfalianas, assim como o impacto desta tecnologia sobre o conceito de território, reiterando, afinal, a pertinência desta categoria geográfica para o estudo do ciberespaço.
Localized Antileptin Therapy Prevents Aortic Root Dilatation and Preserves Left Ventricular Systolic Function in a Murine Model of Marfan Syndrome
Authors: Fisch Sudeshna , Bachner‐Hinenzon Noa , Ertracht Offir , Guo Liang , Arad Yhara , Ben‐Zvi Danny , Liao Ronglih , Schneiderman Jacob
Published: May 2020

Background

Marfan syndrome (
MFS
) is a genetically transmitted connective tissue disorder characterized by aortic root dilatation, dissection, and rupture. Molecularly,
MFS
pathological features have been shown to be driven by increased angiotensin
II
in the aortic wall. Using an angiotensin
II
–driven aneurysm mouse model, we have recently demonstrated that local inhibition of leptin activity restricts aneurysm formation in the ascending and abdominal aorta. As we observed de novo leptin synthesis in the ascending aortic aneurysm wall of patients with MFS, we hypothesized that local counteracting of leptin activity in
MFS
may also prevent aortic cardiovascular complications in this context.

Methods and Results

Fbn1

C1039G/+

mice underwent periaortic application of low‐dose leptin antagonist at the aortic root. Treatment abolished medial degeneration and prevented increase in aortic root diameter (
P
<0.001). High levels of leptin, transforming growth factor β1, Phosphorylated Small mothers against decapentaplegic 2, and angiotensin‐converting enzyme 1 observed in saline‐treated
MFS
mice were downregulated in leptin antagonist–treated animals (
P
<0.01,
P
<0.05,
P
<0.001, and
P
<0.001, respectively). Leptin and angiotensin‐converting enzyme 1 expression levels in left ventricular cardiomyocytes were also decreased (
P
<0.001) and coincided with prevention of left ventricular hypertrophy and aortic and mitral valve leaflet thickening (
P
<0.01 and
P
<0.05, respectively) and systolic function preservation.

Conclusions

Local, periaortic application of leptin antagonist prevented aortic root dilatation and left ventricular valve remodeling, preserving left ventricular systolic function in an
MFS
mouse model. Our results suggest that local inhibition of leptin may constitute a novel, stand‐alone approach to prevent
MFS
aortic root aneurysms and potentially other similar angiotensin
II
–driven aortic pathological features.
Oxidative Stress Is Associated With Diastolic Dysfunction in Women With Ischemia With No Obstructive Coronary Artery Disease
Authors: Raad Mohamad , AlBadri Ahmed , Wei Janet , Mehta Puja K. , Maughan Jenna , Gadh Adit , Thomson Louise , Jones Dean P. , Quyyumi Arshed A. , Pepine Carl J. , Bairey Merz C. Noel
Published: May 2020

Background

Women with signs and symptoms of ischemia and no obstructive coronary artery disease often have evidence of diastolic dysfunction. Oxidative stress (
OS
) is associated with cardiovascular risk factors and adverse outcomes. The relationship between systemic
OS
and diastolic dysfunction is unknown.

Methods and Results

A subgroup of women (n=75) with suspected ischemia and no obstructive coronary artery disease who had both cardiac magnetic resonance imaging and
OS
measurements were enrolled in the
WISE
‐
CVD
(Women Ischemia Syndrome Evaluation—Coronary Vascular Dysfunction) study. Left ventricular end‐diastolic pressure was measured invasively. Left ventricular end‐diastolic volume and peak filling rate were assessed using cardiac magnetic resonance imaging. Aminothiol levels of plasma cystine and glutathione were measured as markers of
OS
. Spearman correlation and linear regression analyses were conducted. The group mean age was 54±11 years, and 61% had a resting left ventricular end‐diastolic pressure >12 mm Hg. Cystine levels correlated negatively with the peak filling rate (
r
=−0.31,
P
=0.007) and positively with left ventricular end‐diastolic pressure (
r
=0.25;
P
=0.038), indicating that increased
OS
was associated with diastolic dysfunction. After multivariate adjustment including multiple known risk factors for diastolic dysfunction and cardiovascular medications, cystine levels continued to be associated with peak filling rate (β=−0.27,
P
=0.049) and left ventricular end‐diastolic pressure (β=0.25;
P
=0.035). Glutathione levels were not associated with indices of diastolic function.

Conclusions

OS
, measured by elevated levels of cystine, is associated with diastolic dysfunction in women with evidence of ischemia and no obstructive coronary artery disease, indicating the role of
OS
in patients with ischemia and no obstructive coronary artery disease. Its role in the progression of heart failure with preserved ejection fraction should be explored further.
A Geometric Characterization of Population Coding in the Prefrontal Cortex and Hippocampus during a Paired-Associate Learning Task
Authors: Liu Yue , Brincat Scott L. , Miller Earl K. , Hasselmo Michael E.
Published: May 2020

Large-scale neuronal recording techniques have enabled discoveries of population-level mechanisms for neural computation. However, it is not clear how these mechanisms form by trial-and-error learning. In this article, we present an initial effort to characterize the population activity in monkey prefrontal cortex (PFC) and hippocampus (HPC) during the learning phase of a paired-associate task. To analyze the population data, we introduce the normalized distance, a dimensionless metric that describes the encoding of cognitive variables from the geometrical relationship among neural trajectories in state space. It is found that PFC exhibits a more sustained encoding of the visual stimuli, whereas HPC only transiently encodes the identity of the associate stimuli. Surprisingly, after learning, the neural activity is not reorganized to reflect the task structure, raising the possibility that learning is accompanied by some “silent” mechanism that does not explicitly change the neural representations. We did find partial evidence on the learning-dependent changes for some of the task variables. This study shows the feasibility of using normalized distance as a metric to characterize and compare population-level encoding of task variables and suggests further directions to explore learning-dependent changes in the neural circuits.
Memory of Others' Disclosures Is Consolidated during Rest and Associated with Providing Support: Neural and Linguistic Evidence
Authors: Collier Eleanor , Meyer Meghan L.
Published: May 2020

Social scientists have documented the power of being heard: Disclosing emotional experiences to others promotes mental and physical health. Yet, far less is known about how listeners digest the sensitive information people share with them. We combined brain imaging and text analysis methods with a naturalistic emotional disclosure paradigm to assess how listeners form memories of others' disclosures. Neural and linguistic evidence support the hypothesis that listeners consolidate memories for others' disclosures during rest after listening and that their ability to do so facilitates subsequently providing the speakers with support. In Study 1, brain imaging methods showed that functional connectivity between the dorsomedial subsystem of the default network and frontoparietal control network increased during rest after listening to others' disclosures and predicted subsequent memory for their experiences. Moreover, graph analytic methods demonstrated that the left anterior temporal lobe may function as a connector hub between these two networks when consolidating memory for disclosures. In Study 2, linguistic analyses revealed other-focused thought increased during rest after listening to others' disclosures and predicted not only memory for the information disclosed but also whether listeners supported the speakers the next day. Collectively, these findings point to the important role of memory consolidation during rest in helping listeners respond supportively to others' disclosures. In our increasingly busy lives, pausing to briefly rest may not only help us care for ourselves but also help us care for others.

Messages from the Expressive Nature of icc Reparations: Complex-victims in Complex Contexts and the Trust Fund for Victims
Authors: Fisher Kirsten J.
Published: May 2020

There are great hopes for the International Criminal Court’s (icc’s) reparative aspirations, which are regarded as an answer to demands for more victim-centric approaches to the pursuit of justice for atrocity crimes. Reparations are recognised as a right of victims, and it seems appropriate that the icc should attempt to combine reparations with its retributive approach to addressing grave human right abuses. However, the potential negative communicative value of icc reparations must not be overlooked. For one, icc reparations have the potential to relieve some suffering but also the potential to exacerbate tensions and compound the challenges of reintegration and acceptance of complex-victims because of their expressive nature. This article argues that it is precisely because of the unique nature of the Court as retributive, as a voice of international condemnation, and as an intervener in complex contexts that the expressive value of its reparations may make it ill-suited to award reparations tied to convictions.
Digital Technology and Pilgrimage: Shiʿi Rituals of Arbaʿin in Iraq
Authors: Rahimi Babak , Amin Mohsen
Published: May 2020

Since the collapse of the Baʿathist regime after the U.S.-led invasion of Iraq in 2003, Shiʿi Muslim rituals, in particular the annual commemorations of Arbaʿin, have seen a revival in popularity. Based on two fieldwork studies conducted during Arbaʿin in 2016 and 2017, the present study attempts to examine the changing characteristics of the rituals. It does so by studying the increasing digitization of Arbaʿin as a commemorative pilgrimage to Karbala, Iraq, to the shrine of the Prophet’s grandson, Imam Husayn. This ethnographic study argues for a mediated conception of Arbaʿin pilgrimage in that digital technologies serve as an embodied site of interaction in shaping shared experiences based on networked sociability. Examining the intimate connections between “physical” and “virtual” spaces, as in the case of Mawakib or gatherings shaped in the form of temporary lodgings in the course of walking processions, the study argues that various uses of digital technologies for pilgrimage are less about means of devotional expression than a series of experiences of digital significance. The paper makes the final argument that the digital practices embedded in ritual processions are acted upon to enhance experience, which increasingly fuses technology with ritual action.
The Experience Megachurch: Lakewood, Hillsong, and The Pragmatics and Semiotics of “Inspiration”
Authors: Goh Robbie B. H.
Published: May 2020

Megachurches, although differing in terms of denominational affiliation (or relative lack thereof), spatial logic, liturgy, teaching, and congregational demographics, share the common trait of size and are often fast-growing churches as well. This is particularly true of what might be called (following scholarship on the “experience economy”) the “experience megachurch”: those with a broad attractive appeal, large and growing congregations, and relative freedom from traditional Christian spatial-architectural constraints, rituals, and denominational histories. Such experience megachurches share an emphasis on offering their congregations an “inspiring” experience of the reality of God’s existence and presence in the church. Applying theories of pragmatics, semiotics, and bodily discipline, this article examines two experience megachurches (Lakewood in Houston, U.S.A., and Hillsong, headquartered in Sydney, Australia) to offer a taxonomy of megachurch praxis.
Periclimenes laevimanus sp. nov. from Vietnam, with a review of the Periclimenes granulimanus species group (Crustacea: Decapoda: Palaemonidae: Pontoniinae)
Authors: ĎURIŠ ZDENĚK
Published: May 2020

A new, hydroid-associated representative of the genus Periclimenes from Vietnam is described and illustrated. P. laevimanus sp. nov. is most similar to P. granulimanus Bruce, 1978, but differs from it by the more slender and smooth, not granulated, major second pereiopod and the non-dentate cutting edges of the minor second pereiopod. A new host is reported for P. granulimanus. Mouth parts are described and illustrated for P. brucei Ď uriš, 1990. This species is easily distinguished by its extremely elongate second pereiopods, with the carpus longer than the chela, and the walking legs lacking simple spines proximally from the distoventral series of paired spines. Periclimenes tonga Bruce, 1990 differs from other members of the species group by having only a single pair of dorsal telson spines. A key for the identification of species of the herein established P. granulimanus species group is provided. Types and/or museum specimens of some other Periclimenes species (P. hongkongensis Bruce, 1969, P. nomadophila Berggren, 1994, P. ruber Bruce, 1982, and P. toloensis Bruce, 1969) were examined to evaluate their relationship with the P. granulimanus species complex.
Two crested and colourful new species of Lebbeus (Crustacea: Caridea: Hippolytidae) from the continental margin of Western Australia
Authors: McCALLUM ANNA W. , POORE GARY C. B.
Published: May 2020

Two new species of hippolytid shrimp are described from the continental margin of Western Australia, Lebbeus clarehannah sp. nov. from one female specimen collected off Bald Island, WA, at depths of 408–431 m and Lebbeus cristagalli sp. nov. from ten specimens collected off north-western Australia at depths of 397–458 m. Both species belong to the group of Lebbeus species possessing epipods on only the first two pairs of pereopods. Within this group, they are similar to L. yaldwyni Kensley, Tranter & Griffin, 1987 from NSW, Australia, and L. compressus Holthuis, 1947 from Japan in possessing a high crest on the carapace. These crested species of Lebbeus are reviewed. They can be distinguished from one another by the shape of the carapace crest, the number of spines on maxilliped 3 and by colour pattern. A key to all crested species and colour photos of the Australian species are provided.
Additions to the genus Phycomenes Bruce, 2008 (Crustacea: Decapoda: Pontoniinae)
Authors: BRUCE A. J.
Published: May 2020

The genus Phycomenes was recently described by Bruce (2008)) for a small sea-grass inhabiting shrimp, Phycomenes zostericola Bruce, 2008, from south-east Queensland, Australia. The close similarity of this species to Periclimenes indicus (Kemp 1915) was noted. Subsequently specimens of Kemp’s species from the type locality, Chilka Lake, Orissa, India, were examined and the most characteristic features of the genus Phycomenes were found to be present, i.e., a transverse triangular median process on the fourth thoracic sternite and the greatly reduced size of the second pereiopods in comparison with other Periclimenes species, with a very well developed ocular ocellus. Periclimenes indicus is therefore transferred to the genus Phycomenes Bruce. Periclimenes cobourgi Bruce & Coombes, 1995 has also been noted as closely similar to Periclimenes indicus, showing the same major features and should also be considered as congeneric with Phycomenes zostericola. Similarly, examination of specimens of Periclimenes sulcatus Ďuriš, Horká, & Marin, 2008, and P. siankaanensis Martínez-Mayén, & Román-Contreras, 2006, kindly donated by Dr Zdenek Ďuriš and Dr Mario Martinez-Mayén to the Queensland Museum, Brisbane, show the same features and should be similarly placed in the genus Phycomenes. Martínez-Mayén and Román-Contreras (2006) considered P. siankaanensis to be a member of the “iridescens” species complex, including also P. iridescens Lebour, 1949, P. platalea Holthuis, 1951, P. antipathophilus Holthuis & Eibl-Eibesfeldt, 1964, P. patae Heard & Spotte, 1991, and P. mclellandi Heard & Spotte, 1997. Periclimenes platalea has recently been removed from this complex and placed in the genus Rapipontonia Marin by Marin (2007). No examples of these species have been examined but it seems likely that some may possibly be better placed in Phycomenes. Some of these taxa have been reported as associates of coelenterate hosts rather than from sea-grass habitat, but such a coelenterate association has also been reported in the case of the holotype specimen of P. cobourgi found on a gorgonian host. The specimens of P. indicus were kindly donated by the Zoological Survey of India, Calcutta (ZSI). The specimens examined are deposited in the collections of the Northern Territory Museum, Darwin (NTM) and Queensland Museum, Brisbane (QM).

Published: May 2020

Microlaimus sergeevae sp. n. is described and illustrated from the Crimea shelf of the Black Sea. It is characterized by the 1301–1728 μm long body; cuticle with distinct annuli; spicules 34–37 μm long, curved; gubernacular apophyses 20–25 μm long, surrounding distal end of spicules; criptocyrcular amphidial fovea 7–8 μm in diameter; cervical setae present; four submedian rows of pores spreading along the whole body length, and eight precloacal supplements in males. The new species morphologically resembles M. gerlachi Wieser 1954, M. paraborealis Allgen 1940a and M. kaurii Wieser 1954, but differs from them by the length of cephalic setae, size of the body, presence of cervical setae, shape of the gubernacular apophyses, eight tubular precloacal supplements and submedian rows of pores spreading along the whole body length. M. sergeevae sp. n. differs from M. gerlachi by having a smaller amphidial fovea, shorter spicules and gubernacular apophyses. The new species differs from M. paraborealis by having larger value of c. It differs from M. kaurii by having longer spicules and larger values of c and b.
The Critical Role of Non-Normality in Partitioning Tropical and Extratropical Contributions to PNA Growth
Authors: Henderson Stephanie A. , Vimont Daniel J. , Newman Matthew
Published: May 2020

The Pacific–North American (PNA) teleconnection pattern has been linked both to tropical phenomena, including the Madden–Julian oscillation (MJO) and El Niño–Southern Oscillation (ENSO), and to internal extratropical processes, including interactions with the zonally varying basic state and synoptic eddies. Many questions remain, however, concerning how these various relationships act, both separately and together, to yield observed PNA variability. Using linear inverse modeling (LIM), this study finds that the development and amplification of PNA anomalies largely results from the interference of modes strongly coupled to sea surface temperatures (SST), such as ENSO, and modes internal to the atmosphere, including the MJO. These SST-coupled and “internal atmospheric” modes form subspaces that are not orthogonal, and PNA growth is shown to occur via non-normal interactions. An internal atmospheric space LIM is developed to examine growth beyond this interference by removing the SST-coupled modes, effectively removing ENSO and retaining MJO variability. Optimal PNA growth in the internal atmospheric space LIM is driven by MJO heating, particularly over the Indian Ocean, and a retrograding northeast Pacific streamfunction anomaly. Additionally, the individual contributions of tropical heating and the extratropical circulation on PNA growth are investigated. The non-normal PNA growth is an important result, demonstrating the difficulty in partitioning PNA variance into contributions from different phenomena. This cautionary result is likely applicable to many geophysical phenomena and should be considered in attribution studies.

Published: May 2020

Violent interaction detection is a hot topic in computer vision. However, the recent research works on violent interaction detection mainly focus on the traditional hand-craft features, and does not make full use of the research results of deep learning in computer vision. In this paper, we propose a new robust violent interaction detection framework based on multi-stream deep learning in surveillance scene. The proposed approach enhances the recognition performance of violent action in video by fusing three different streams: attention-based spatial RGB stream, temporal stream, and local spatial stream. The attention-based spatial RGB stream learns the spatial attention regions of persons that have high probability to be action region through soft-attention mechanism. The temporal stream employs optical flow as input to extract temporal features. The local spatial stream learns spatial local features using block images as input. Experimental results demonstrate the effectiveness and reliability of the proposed method on three violent interactive datasets: hockey fights, movies, violent interaction. We also verify the proposed method on our own elevator surveillance video dataset and the performance of the proposed method is satisfied.
Drought, Resilience, and Support for Violence: Household Survey Evidence from DR Congo

Published: May 2020

The effects of climate variability and change on security are debated. While this topic has received considerable attention in both policy circles and academia, the microlevel pathways and conditions under which climatic shocks increase conflict risks are poorly understood. We suggest that household resilience provides one key to understanding these relationships. Using novel household survey data from two conflict-affected regions in Eastern Democratic Republic of the Congo, we study variation in the support for violence related to reported exposure to drought and resilience metrics. Using comprehensive multifaceted objective and subjective indicators of resilience, we find that less resilient respondents who report having experienced drought and associated losses are more likely to be supportive of the use of political violence. In contrast, our findings suggest that there is no general association between reporting drought exposure and support for violence.

Although complicated grief (CG) following the death of a loved one has traditionally been viewed as avoidance-driven, recent research implicates approach behavior. Researchers have investigated how coping styles predict CG; however, emotional closeness remains unexamined. This study investigated the differential relationship of approach- and avoidance-focused coping on CG and depressive symptoms. Bereaved adults ( n = 340) completed questionnaires about their loss, coping styles, CG, and depression. Results suggest that approach-, but not avoidance-, focused coping mediates the relationship of emotional closeness on CG, while emotional closeness of the relationship had no direct impact on depressive symptoms. This suggests closeness of the relationship plays a unique role in CG.

Physical exercise declines during adolescence due to several factors, such as lack of intrinsic motivation or enjoyment, high physical exercise anxiety, and so on. The objectives of this study were to validate the psychometric structure of the Behavioral Regulation in Exercise Questionnaire-2 to confirm the existence of five levels of motivation toward physical exercise in adolescent population, as well as to analyze the differences in motivation according to sex and age, and the role of age and sex in the relationship between motivation and enjoyment. To do so, 666 students between 10 and 16 years old completed the Behavioral Regulation in Exercise Questionnaire-2 and questionnaires related to enjoyment and physical exercise anxiety. The confirmatory factor analysis of the Behavioral Regulation in Exercise Questionnaire-2 showed a five-factor structure. However, a more parsimonious four-factor structure with a single intrinsic-identified regulation emerged through an exploratory factor analysis. The more self-determined types of motivation were positively associated with enjoyment and negatively with anxiety, the type of physical exercise motivation fluctuated depending on age and sex, and the age moderated the relationship between motivation and enjoyment. This study highlights the importance of fostering specific types of motivation to improve the physical exercise and the relevance of age and sex when developing interventions.
Stability analysis of underground water-sealed oil storage caverns in China：A case study
Authors: Xingdong Zhao , Lei Deng , Shujing Zhang
Published: May 2020

The stability of underground water-sealed oil storage caverns is of great importance for safe excavation and operation. To analyze the scope of the failure zone and underground cavern stability accurately, a new method was developed that integrates the rock tunneling quality index Q-system and stability graph method with 3D laser scanning and numerical simulation. The point cloud data were obtained by 3D laser scanning, and the cavern model was built by using DIMINE software, which directly shows the 3D shape of the cavern. The rock mass physical and mechanical parameters and the corresponding stability coefficients were obtained based on Q-system and stability graph method. The plastic zone distribution and deformation characteristics of surrounding rock were analyzed through numerical simulation. Then, the corresponding relationship between caving zone and plastic zone was determined by comparing the numerical simulation results with the 3D laser scanning contour. The new method provides a reliable way to analyze the stability of the underground water-sealed oil storage cavern and also will helpful to design or optimize the subsequent support.
The Impact of Long-Term Care Policy on the Percentage of Older Adults With Disabilities Cared for by Family Members in China: A System Dynamics Simulation
Authors: Peng Rong , Wu Bei
Published: May 2020

This study examined the impact of current and future long-term care (LTC) policies on the family caregiving burden in China. System dynamics (SD) methodology was used to construct an LTC delivery system model that simulates the demand of LTC, living options, and LTC service use for disabled older adults. The model was based on three policy variables including the proportion of payment from LTC insurance, the growth rate of beds in LTC institutions, and the time to adjusting the capacity of community-based care. Results showed that the percentage of older adults with disabilities cared for by family members was projected to increase from 92.6% in 2015 to 97.8% in 2035, assuming no policy changes; under the mixed policy scenario, this percentage would reduce significantly to 63.8% in 2035. These findings illustrate that changes in LTC policy and delivery system have a significant impact on family care.
Freedom as critique: Foucault beyond anarchism
Authors: Schubert Karsten
Published: May 2020

Foucault’s theory of power and subjectification challenges common concepts of freedom in social philosophy and expands them through the concept of ‘freedom as critique’: Freedom can be defined as the capability to critically reflect upon one’s own subjectification, and the conditions of possibility for this critical capacity lie in political and social institutions. The article develops this concept through a critical discussion of the standard response by Foucault interpreters to the standard objection that Foucault’s thinking obscures freedom. The standard response interprets Foucault’s later works, especially The Subject and Power, as a solution to the problem of freedom. It is mistaken, because it conflates different concepts of freedom that are present in Foucault’s work. By differentiating these concepts, this article proposes a new institutionalist approach to solve the problem of freedom that breaks with the partly anarchist underpinnings of Foucault scholarship: As freedom as critique is not given, but itself a result of subjectification, it entails a demand for ‘modal robustness’ and must therefore be institutionalized. This approach helps to draw out the consequences of Foucault’s thinking on freedom for postfoundationalist democratic theory and the general social-philosophical discussion about freedom.
The effect of response order on candidate viewing behaviour and item difficulty in a multiple-choice listening test

Published: May 2020

Studies from various disciplines have reported that spatial location of options in relation to processing order impacts the ultimate choice of the option. A large number of studies have found a primacy effect, that is, the tendency to prefer the first option. In this paper we report on evidence that position of the key in four-option multiple-choice (MC) listening test items may affect item difficulty and thereby potentially introduce construct-irrelevant variance.

Two sets of analyses were undertaken. With Study 1 we explored 30 test takers’ processing via eye-tracking on listening items from the Aptis Test. An unexpected finding concerned the amount of processing undertaken on different response options on the MC questions, given their order. Based on this, in Study 2 we looked at the direct effect of key position on item difficulty in a sample of 200 live Aptis items and around 6000 test takers per item.

The results suggest that the spatial location of the key in MC listening tests affects the amount of processing it receives and the item’s difficulty. Given the widespread use of MC tasks in language assessments, these findings seem crucial, particularly for tests that randomize response order. Candidates who by chance have many keys in last position might be significantly disadvantaged.
Deplatforming: Following extreme Internet celebrities to Telegram and alternative social media
Authors: Rogers Richard
Published: May 2020

Extreme, anti-establishment actors are being characterized increasingly as ‘dangerous individuals’ by the social media platforms that once aided in making them into ‘Internet celebrities’. These individuals (and sometimes groups) are being ‘deplatformed’ by the leading social media companies such as Facebook, Instagram, Twitter and YouTube for such offences as ‘organised hate’. Deplatforming has prompted debate about ‘liberal big tech’ silencing free speech and taking on the role of editors, but also about the questions of whether it is effective and for whom. The research reported here follows certain of these Internet celebrities to Telegram as well as to a larger alternative social media ecology. It enquires empirically into some of the arguments made concerning whether deplatforming ‘works’ and how the deplatformed use Telegram. It discusses the effects of deplatforming for extreme Internet celebrities, alternative and mainstream social media platforms and the Internet at large. It also touches upon how social media companies’ deplatforming is affecting critical social media research, both into the substance of extreme speech as well as its audiences on mainstream as well as alternative platforms.
Differentiation between non-hypervascular pancreatic neuroendocrine tumors and mass-forming pancreatitis using contrast-enhanced computed tomography

Published: May 2020

Background

Non-hypervascular pancreatic neuroendocrine tumors (PNETs) showed slight or iso-enhancement in contrast-enhanced computed tomography (CE-CT), which shared similar imaging findings with mass-forming pancreatitis (MFPs).

Purpose

To explore the value of CT imaging features in differentiating the two diseases.

Material and Methods

Fifty-one patients with histologically proved MFPs (n = 27) or non-hypervascular PNETs (n = 24) were included. Two radiologists reviewed CT imaging findings and clinical features. Logistic regression analysis was performed to identify relevant features in differentiating non-hypervascular PNETs and MFPs. Receiver operating characteristic (ROC) curve analysis was used to show the performance of the optimal parameters in differentiating non-hypervascular PNETs and MFPs.

Results

A well-defined margin was more common in non-hypervascular PNETs ( P < 0.05) than that in MFPs. MFPs often occurred in older people ( P < 0.01) and the head–neck of the pancreas compared with non-hypervascular PNETs ( P < 0.05). Metastases only presented in non-hypervascular PNETs ( P < 0.05). CT values at venous phase and delay phase of MFPs were higher ( P = 0.010 and P = 0.029) than those in non-hypervascular PNETs. Logistic analysis showed gender, tumor margin, CT values at venous phase, and tumor components were independent predictors in differentiating the two lesions. The area under the curve (AUC) was 0.938 with a sensitivity of 87.5% and specificity of 92.6% for combined predicators.

Conclusion

Gender, tumor margin, CT values at venous phase, and tumor components were useful predicators in differentiating non-hypervascular PNETs and MFPs.
