Single‐Atom Nanozyme Based on Nanoengineered Fe–N–C Catalyst with Superior Peroxidase‐Like Activity for Ultrasensitive Bioassays
Authors: Cheng Nan , Li Jin‐Cheng , Liu Dong , Lin Yuehe , Du Dan 
Published: May 2019

AbstractSingle‐atom catalysts are becoming a hot research topic owing to their unique characteristics of maximum specific activity and atomic utilization. Herein, a new single‐atom nanozyme (SAN) based on single Fe atoms anchored on N‐doped carbons supported on carbon nanotube (CNT/FeNC) is proposed. The CNT/FeNC with robust atomic Fe–Nx
moieties is synthesised, showing superior peroxidase‐like activity. Furthermore, the CNT/FeNC is used as the signal element in a series of paper‐based bioassays for ultrasensitive detection of H2O2, glucose, and ascorbic acid. The SAN provides a new type of signal element for developing various biosensing techniques.

Published: May 2019

AbstractThe ability of living systems to self‐sort different cells into separate assemblies and the ability to independently regulate different structures are one ingredient that gives rise to their spatiotemporal complexity. Here, this self‐sorting behavior is replicated in a synthetic system with two types of colloidal particles; where each particle type independently self‐assembles either under blue or red light into distinct clusters, known as narcissistic self‐sorting. For this purpose, each particle type is functionalized either with the light‐switchable protein VVDHigh or Cph1, which homodimerize under blue and red light, respectively. The response to different wavelengths of light and the high specificity of the protein interactions allows for the independent self‐assembly of each particle type with blue or red light and narcissistic self‐sorting. Moreover, as both of the photoswitchable protein interactions are reversible in the dark; also, the self‐sorting is reversible and dynamic. Overall, the independent blue and red light controlled self‐sorting in a synthetic system opens new possibilities to assemble adaptable, smart, and advanced materials similar to the complexity observed in tissues.

Published: May 2019

AbstractThe di (2‐ethylhexyl) phthalate (DEHP) is a plasticizer used in the polyvinyl chloride industry. Human exposure to this plasticizer is inevitable and contributes to several side effects. In this study, we examined whether DEHP induces apoptosis and oxidative stress in embryonic kidney cells (HEK‐293) and whether the nuclear factor E2‐related factor 2 (Nrf‐2)/heme oxygenase‐1 (HO‐1) antioxidant pathway is involved in the pathogenesis of this process. We demonstrated that DEHP is cytotoxic to HEK‐293 cells. It causes oxidative damage through the generation of free radicals, induces lipid peroxidation, and alters superoxide dismutase and catalase activities. Simultaneously, DEHP treatment decreases the expression and the protein level of Nrf‐2 and HO‐1. Inhibition of the Nrf‐2/HO‐1 pathway is related to the mitochondrial pathway of apoptosis. This apoptotic process is characterized by a loss of mitochondrial transmembrane potential (ΔΨm) and upregulation of the expression of caspase‐3 mRNA as well as its protein level.

Published: May 2019

ABSTRACT
In the present study, geologic lineaments have been extracted by automatic lineament extraction algorithm of Geomatica software, using digital elevation model (DEM) derived shaded relief images being illuminated with multiple illumination directions. Fieldwork has been carried out for ground truth and in search of any possible evidence of movement along the extracted lineaments in the Kandiah valley in Kohistan district. A regional lineament (possible fault) has been inferred in recent a geological study (e.g. Zeilinger, 2002) that has been found to cross the Kandiah valley. The analysis and ground verification of automatic extracted geologic lineaments revealed that Kandiah valley is in one block without having any regional geological lineament. However, a good correlation was found among the predominant orientations of extracted geologic lineaments and the measured trends of rock features such as rock foliation, drainage pattern and linear ridges. Based on extracted lineaments, no pronounced lineament or fault with the regional extension was identified. This finding is consistent with the field observations as no defenite evidence of fault was found in the study area.
Stressful life events and well‐being among rural‐to‐urban migrant adolescents: The moderating role of the stress mindset and differences between genders
Authors: Jiang Ying , Zhang Jing , Ming Hua , Huang Silin , Lin Danhua 
Published: May 2019

ABSTRACTIntroductionRecent empirical studies have shown that the stress mindset is an implicit belief about stress and that the stress‐is‐enhancing mindset attenuates the negative effects of stressful life events on psychological and behavioral outcomes. Migrant adolescents experience more adverse life events, which are potential risk factors that can decrease their well‐being. This study first explored the relationship between stressful life events and well‐being (depression and life satisfaction) among Chinese rural‐to‐urban migrant adolescents. Furthermore, we examined the protective role of the enhancing stress mindset in this relationship and the moderating effect of gender.MethodsIn total, 396 Chinese rural‐to‐urban migrant adolescents aged between 10 and 14 years (M = 11.75 years,SD = 1.16) completed a battery of self‐report questionnaires concerning their stressful life events, stress mindsets, depression and life satisfaction.ResultsThe hierarchical multiple regressions showed that stressful life events were positively associated with depression and negatively associated with life satisfaction. Compared to the adolescents with the stress‐is‐debilitating mindset, the adolescents with the stress‐is‐enhancing mindset were less prone to depression when faced with more stressful life events. Furthermore, the stress mindset was positively linked to life satisfaction among the girls but not the boys.ConclusionsThese findings suggest that the stress‐is‐enhancing mindset is a protective factor that may help migrant adolescents mitigate adversity and improve their well‐being.
The Social Dimension of EU State Aid Law and Policy
Authors: FERRI Delia , PIERNAS LÓPEZ Juan Jorge 
Published: May 2019

AbstractTraditionally, EU state aid law has been attached to the goals of maintaining free competition and preventing the distortionary effects of Member States’ economic intervention, while social considerations have been considered immaterial to state aid control. However, in more recent years, EU state aid law has acquired a clearer ‘social dimension’, indirectly streamlining national subsidies towards social goals. The entry into force of the Treaty of Lisbon, and particularly of Articles 3(3) TEU and 9 TFEU, has had an impact on the way in which social goals have been taken into account in the application of the state aid provisions. In the last decade, the European Commission has sought out a more appropriate balance between the main objective of preserving competition in the internal market on the one hand, and social objectives, also enshrined nowadays in the Treaties, on the other. This ‘social dimension’ is still underdeveloped, but emerges to varying degrees when looking respectively at the definition of state aid under Article 107(1) TFEU, at the scope of the derogations under Articles 107(2) and 107(3) TFEU and at the secondary legislation adopted for their implementation.
The European Pillar of Social Rights: An Assessment of its Meaning and Significance
Authors: GARBEN Sacha 
Published: May 2019

AbstractThe European Pillar of Social Rights is a high-profile political reaffirmation of twenty social rights and principles. Its implementation deploys the full EU governance arsenal: regulations, directives, recommendations, communications, new institutions, funding actions, and country-specific recommendations. As such, the static imagery evoked by a ‘pillar’ does not capture the true nature of the initiative, which is dynamic and fluid, wide-ranging, and permeating. An equation of the Pillar with the set of twenty rights and principles it proclaims similarly fails to capture its true significance, which lies in its programmatic nature. Several important measures have already been proposed as part of this new social action plan for Europe, some of which are close to adoption. This Article analyses the meaning of the Pillar and its potential significance, by considering its contentsensu largo, and its broader context. It argues that even if the Pillar cannot address all the EU's social failings, it has put a surprising social spin on the Better Regulation Agenda that was threatening to erode the socialacquis, it has rekindled the EU's relationship with the International Labour Organization and Council of Europe, and it helps rebalance the EU's output by reviving the use of the Treaty's Social Title.

Published: May 2019

ABSTRACT:Background: Advances in multiple sclerosis (MS) disease modifying therapy (DMT) have increased laboratory monitoring requirements. Our goal was to survey existing practices and perceptions of risk in laboratory monitoring throughout Canada and assess whether opportunities to improve patient care and safety exist. Methods: A web-based survey assessing prescriber demographics, current infrastructure, and concerns for lab monitoring was sent to the Canadian Network of MS Clinics (CNMSC) listserv, inviting MS clinicians across the country to participate. Results: Respondents included 32/65 CNMSC-affiliated neurologists (49%), 6 registered nurses (RN), 2 nurse practitioners (NP), and 2 non-neurologist physicians from 8/10 provinces. For some questions, analysis was limited to 34 DMT-prescribing clinicians only. Despite broad implementation of electronic medical records (25/34, 74%), many prescribers (15/34, 44%) still receive laboratory results in paper form. In terms of lab monitoring infrastructure, we noted regional variability in the employment of nursing to monitor patient compliance with required laboratory monitoring. There is also a gap in laboratory surveillance, as less than 5% of respondents reported regularly reviewing results on weekends. Providers’ length of practice and volume of MS patients were not associated with different perception of DMT laboratory monitoring risk. Conclusions: This nation-wide survey showed variability in infrastructure used in laboratory monitoring and regional variation in nursing involvement. Providers’ level of concern for laboratory monitoring for DMTs did not vary by years of experience or volume of MS patients followed, suggesting that improved systems, rather than education, could ameliorate perceptions of risk.

Streamwise velocity and wall-shear stress are acquired simultaneously with a hot-wire and an array of azimuthal/spanwise-spaced skin friction sensors in large-scale pipe and boundary layer flow facilities at high Reynolds numbers. These allow for a correlation analysis on a per-scale basis between the velocity and reference skin friction signals to reveal which velocity-based turbulent motions are stochastically coherent with turbulent skin friction. In the logarithmic region, the wall-attached structures in both the pipe and boundary layers show evidence of self-similarity, and the range of scales over which the self-similarity is observed decreases with an increasing azimuthal/spanwise offset between the velocity and the reference skin friction signals. The present empirical observations support the existence of a self-similar range of wall-attached turbulence, which in turn are used to extend the model of Baarset al.(J. Fluid Mech., vol. 823, p. R2) to include the azimuthal/spanwise trends. Furthermore, the region where the self-similarity is observed correspond with the wall height where the mean momentum equation formally admits a self-similar invariant form, and simultaneously where the mean and variance profiles of the streamwise velocity exhibit logarithmic dependence. The experimental observations suggest that the self-similar wall-attached structures follow an aspect ratio of$7:1:1$in the streamwise, spanwise and wall-normal directions, respectively.
Does group cohesion moderate associations between attachment, caregiving, and OCB?

Published: May 2019

AbstractThis research focused on the role of group cohesion as moderating the psychological manifestations of attachment and caregiving in performing organizational citizenship behaviors (OCBs). Data were collected from 147 employees, who took part in a 9-week training course. Participants completed questionnaires assessing their attachment and caregiving dimensions as well as group cohesion. Participant OCB levels were assessed by their trainers at the end of the course. Anxious individuals tended to express higher levels of OCB-individual under high levels of group cohesion. However, compulsive caregivers tended to perform OCBI under low levels of group cohesion. The results highlight the contribution of Bowlby's relational perspective in work settings and the importance of contextual factors in predicting OCB.
Charismatic leadership: Beyond love and hate and toward a sense of belonging?
Authors: Parry Ken , Cohen Michael , Bhattacharya Sukanto , North-Samardzic Andrea , Edwards Gareth 
Published: May 2019

AbstractDeveloping previous work on charismatic leadership by Boas Shamir and Ken, we investigate the contention that followers of charismatic leaders have an emotional connection with that leader in the form of a ‘sense of belonging’ and links to community. We, therefore, investigate whether there is any evidence of a sense of belonging when people describe those they judge to be charismatic. Using a mixed-methods aesthetic narrative approach, we are able to supply empirical support for the existence of such a relationship and to extend the findings of previous studies by incorporating the connection that the leader has with the community, in general, as an important factor in the leader–follower relationship.

Published: May 2019

AbstractAs part of comprehensive research on the ethical climate in the Serbian tourism industry, this study examines the effects of selected predictors (job department, individual values and employees’ perspective) on the perception of ethical climate types as well as the relationship between the type of ethical climate, and job satisfaction. Additionally, this study tests these goals for both managers and their subordinates. Research was conducted in 2013, on a sample of 258 employees in different small and medium tourism organizations in Serbia. The findings revealed new information on both ethical climate and job satisfaction-related factors in small and medium tourism enterprises in a non-Western, transitional economy, where ethical behavior is influenced by constant social and economic changes. Several theoretical and managerial implications and future research opportunities were derived from the findings.
Coherence and Continuity: A Study in Comparative Codification
Authors: Fassberg Celia Wasserstein 
Published: May 2019

The English common law is frequently referred to as a seamless web; continental lawyers tend rather to think of law in terms of internal coherence and consistency. This is not merely a linguistic fact, and the terms are not simply interchangeable. Each reflects the characteristic mode of thought and of development in its respective system: the common law constantly and gradually emerging as a cumulative historical process; continental law stemming from, and in every case ultimately resting on interpretation of, codes, the product of a moment in history. Thus, although they are both capable of denoting the same idea of wholeness, each term has a slightly different connotative emphasis, the one stressing historical coherence and the other emphasising conceptual coherence.This is but one example of the proposition that institutions can not be imported wholesale, that foreign legal provisions, and terms of thought and reference, have to be evaluated beyond their immediate superficial appearance before they may be adopted or used as measures for local purposes. All such institutions have both a historical and a contextual significance which makes comparison on the level of one-dimensional questions such as, “Which is the better rule or the more attractive term?” meaningless.

AbstractAssociations have been shown between father’s absence and menarcheal age, but most studies have focused on absence resulting from divorce, abandonment or death. Little research has been conducted to evaluate the effect on menarcheal age of paternal absence through migrant work. In a sample of 400 middle school students, this study examined the association between paternal migrant work and menarcheal age against a backdrop of extensive rural-to-urban migration in China. Data were collected through a self-reported questionnaire, including social-demographic characteristics, aspects of family relationships, information about father’s migrant work and age at menarche. After adjusting for BMI, parent marital status and perceived relationship with mother, lower self-perceived quality of father–daughter relationship (both ‘father present, relationship poor’ and ‘father absent, relationship poor’) and lower frequency of contact with the father were associated with higher odds for early menarche. These findings suggest that the assumption that father’s absence for work influences the timing of menarche needs to be examined in the context of the quality of the father–daughter relationship and paternal care, which appear to play a critical role in the timing of menarche. These findings also emphasize the importance of enhancing paternal involvement and improving father–daughter relationships in the development of appropriate reproductive strategy in daughters.
Effects of habitat alteration and disturbance by humans and exotic species on fosaCryptoprocta feroxoccupancy in Madagascar's deciduous forests

Published: May 2019

AbstractAnthropogenic habitat alteration and invasive species are threatening carnivores globally. Understanding the impact of these factors is critical for creating localized, effective conservation programmes. Madagascar's Eupleridae have been described as the least studied and most threatened group of carnivores. We investigated the effects of habitat degradation and the presence of people and exotic species on the modelled occupancy of the endemic fosaCryptoprocta ferox, conducting camera-trap surveys in two western deciduous forests, Ankarafantsika National Park and Andranomena Special Reserve. Our results indicated no clear patterns between habitat degradation and fosa occupancy but a strong negative association between catsFelissp. and fosas. Cat occupancy was negatively associated with birds and positively associated with contiguous forest and narrow trails. In contrast, dogCanis lupus familiarisoccupancy was best predicted by wide trails, degraded forest and exotic civets. Our results suggest fosas are capable of traversing degraded landscapes and, in the short term, are resilient to contiguous forest disturbance. However, high occupancy of cats and dogs in the landscape leads to resource competition through prey exploitation and interference, increasing the risk of transmission of potentially fatal diseases. Management strategies for exotic carnivores should be considered, to reduce the widespread predation of endemic species and the transmission of disease.
