Name complexity, cognitive fluency, and asset prices
Authors: Fang Chenjun , Zhu Ning 
Published: February 2019

AbstractWe document three interesting phenomena in the Chinese stock market related to the complexity of stock tickers: Companies with more complex stock tickers are (1) held by fewer investors; (2) witness a lower turnover; and (3) experience lower returns during post‐IPO period. The change‐in‐change analysis based on ticker‐changing events generates consistent results. Such results are strong among companies with a higher level of individual investor ownership and stronger information asymmetry. Our findings confirm and extend Green and Jame (Journal of Financial Economics, 2013, 109:813–834) and support that cognitive fluency and name recognition influence investor behavior and asset prices.
Is tetherin a true antiviral: The influenza a virus controversy
Authors: Sharma Anshika , Lal Sunil K. 
Published: February 2019

SummaryTetherin, an interferon‐inducible gene was first discovered to be an antiviral factor in 2008. A vast range of viruses, such as influenza A virus (IAV), dengue virus, Ebola virus, HIV, and RSV, have been reported to be susceptible to the antiviral activity of tetherin. Multiple reports have been published encompassing the role of tetherin in the IAV life cycle. To date, nine reports have been published regarding the role of tetherin in the IAV life cycle, with four reports supporting tetherin as an antiviral factor while five other reports suggesting no effect. To this end, this review summarizes the list of viruses currently known to be inhibited by tetherin and describes mechanisms used by viruses to overcome the antiviral potential of tetherin. Further, using IAV as disease model, we provide existing evidence in favor and against tetherin being considered as an antiviral candidate. Subsequent analysis of the experimental procedures across IAV‐tetherin published reports revealed that the experimental setup (ie, cell lines, transfection reagents, and multiplicity of infection), strain‐specific activity of NS1, and differing roles of NS1 in different cell lines may add up to the contributing factors leading to the discrepancies observed.
Coupling O2 and K2S2O8 Dual Co‐reactant with Fe‐N‐C Modified Electrode for Ultrasensitive Electrochemiluminescence Signal Amplification

Published: February 2019

AbstractThe sensitivity of electrochemiluminescence (ECL) sensor relies on the co‐reactant and the electrode modification materials. Herein, dual co‐reactants (O2 and K2S2O8) and porous carbon with doped N and Fe3O4 (Fe‐N−C) materials modified electrode were proposed for ECL signal amplification in a quantum dots (QDs) ECL system. Firstly, Fe‐N−C materials were synthesized and the effect of pyrolysis temperature on Fe‐N−C materials was evaluated towards ECL intensity. The developed ECL sensor exhibited high sensitivity and specificity towards oxytetracycline (OTC) detection with a detection limit of 0.27 pM (≈ 0.12 ng L−1). Doped N in porous Fe‐N−C materials not only promoted the O2 reduction reaction (ORR) but also accelerated the conversion of Fe2+/Fe3+ in Fe3O4, which catalyzed co‐reactants to their relevant free radicals (SO4⋅− and ⋅OH). Moreover, the decomposition efficiency of K2S2O8 and generation of free radical were promoted through the reaction between OH⋅ and K2S2O8, as well as SO4⋅− and H2O. Therefore, the amounts of excited QDs were increased via the energy and electron transfer process between QDs and free radicals, resulting in a highly enhanced ECL signal. The proposed signal amplification strategy offered an efficient way to improve the catalytic activity of ECL reagents and to boost the sensitivity of ECL sensors.
Overcoming Biological Barriers in Neuroblastoma Therapy: The Vascular Targeting Approach with Liposomal Drug Nanocarriers

Published: February 2019

AbstractNeuroblastoma is a rare pediatric cancer characterized by a wide clinical behavior and adverse outcome despite aggressive therapies. New approaches based on targeted drug delivery may improve efficacy and decrease toxicity of cancer therapy. Furthermore, nanotechnology offers additional potential developments for cancer imaging, diagnosis, and treatment. Following these lines, in the past years, innovative therapies based on the use of liposomes loaded with anticancer agents and functionalized with peptides capable of recognizing neuroblastoma cells and/or tumor‐associated endothelial cells have been developed. Studies performed in experimental orthotopic models of human neuroblastoma have shown that targeted nanocarriers can be exploited for not only decreasing the systemic toxicity of the encapsulated anticancer drugs, but also increasing their tumor homing properties, enhancing tumor vascular permeability and perfusion (and, consequently, drug penetration), inducing tumor apoptosis, inhibiting angiogenesis, and reducing tumor glucose consumption. Furthermore, peptide‐tagged liposomal formulations are proved to be more efficacious in inhibiting tumor growth and metastatic spreading of neuroblastoma than nontargeted liposomes. These findings, herein reviewed, pave the way for the design of novel targeted liposomal nanocarriers useful for multitargeting treatment of neuroblastoma.

Published: February 2019

AbstractLow‐dimensional semiconductors have attracted considerable attention due to their unique structures and remarkable properties, which makes them promising materials for a wide range of applications related to electronics and optoelectronics. Herein, the preparation of 1D Sb2Se3 nanowires (NWs) with high crystal quality via chemical vapor deposition growth is reported. The obtained Sb2Se3 NWs have triangular prism morphology with aspect ratio range from 2 to 200, and three primary lattice orientations can be achieved on the sixfold symmetry mica substrate. Angle‐resolved polarized Raman spectroscopy measurement reveals strong anisotropic properties of the Sb2Se3 NWs, which is also developed to identify its crystal orientation. Furthermore, photodetectors based on Sb2Se3 NW exhibit a wide spectral photoresponse range from visible to NIR (400–900 nm). Owing to the high crystallinity of Sb2Se3 NW, the photodetector acquires a photocurrent on/off ratio of about 405, a responsivity of 5100 mA W−1, and fast rise and fall times of about 32 and 5 ms, respectively. Additionally, owing to the anisotropic structure of Sb2Se3 NW, the device exhibits polarization‐dependent photoresponse. The high crystallinity and superior anisotropy of Sb2Se3 NW, combined with controllable preparation endows it with great potential for constructing multifunctional optoelectronic devices.

A survey on UML model smells detection techniques for software refactoring
Authors: Mumtaz Haris , Alshayeb Mohammad , Mahmood Sajjad , Niazi Mahmood 
Published: February 2019

AbstractBad smells tend to have a negative impact on software by degrading its quality. It is beneficial to detect model smells to avoid their propagation to later stages of software development. The objective of this paper is to present the state‐of‐the‐art research on techniques for detecting UML model bad smells. The detection techniques are compared and evaluated using a proposed evaluation framework. The framework consists of two parts. The first part of the framework compares the techniques in terms of the implemented approach, the investigated model, and the explored model smells, while the experimental design is explored in the second part of the framework. We found that the detection of bad smells in class and sequence diagrams is accomplished via design patterns, software metrics, and predefined rules, while model smells in use cases are detected using metrics and predefined rules. We also found that the class diagram is the most investigated UML model in the context of model smell detection, whereas there is a lack of work on other UML models. In addition, there is a scarcity of independent studies on sequence diagrams. Furthermore, the studies investigating class diagrams are mostly validated, whereas use case diagrams and sequence diagrams are rarely validated.
Modular forms in the spectral action of Bianchi IX gravitational instantons

Published: February 2019

AbstractWe prove a modularity property for the heat kernel and the Seeley-deWitt coefficients of the heat kernel expansion for the Dirac-Laplacian on the Bianchi IX gravitational instantons. We prove, via an isospectrality result for the Dirac operators, that each term in the expansion is a vector-valued modular form, with an associated ordinary (meromorphic) modular form of weight 2. We discuss explicit examples related to well known modular forms. Our results show the existence of arithmetic structures in Euclidean gravity models based on the spectral action functional.

ABSTRACT

Background:
The satisfaction of surgical residents with their training programs is a key indicator for program effectiveness. This survey was conducted to assess the level of perceived satisfaction of surgical residents with the current training programs in Eastern Saudi Arabia.

Materials and methods:
Resident satisfaction was measured by questionnaire in 119 selected participants at 9 training centers in Eastern Saudi Arabia, as part of the general surgery residency program of Saudi Commission for Health Specialties.

Results:
The survey response rate was 69.7% (83/119) resident participants. A total of 37 (44.6%) residents expressed dissatisfaction with their current training programs. The residents were least satisfied with research opportunities (78.3%), followed by faculty didactic involvement (59%), mentorship (51.8%), and case volume (41%) offered in their programs.

Conclusion:
The general low level of satisfaction among surgical residents in Eastern Saudi Arabia warrants a national review of the current programs. Resident satisfaction should be considered as a potent factor while conferring accreditation to surgical training programs across the country.

National Action Plans on Business and Human Rights: Progress or Mirage?
Authors: CANTÚ RIVERA Humberto 
Published: February 2019

AbstractAs of October 2018, 21 states have adopted National Action Plans on Business and Human Rights (NAPs), with several more in different phases of development. This is an important political step to raise awareness of the importance of intragovernmental policy coherence and of the need to move forward to prevent human rights abuses linked to business activity. However, despite the global intergovernmental support to such policy strategies, the actual effectiveness of NAPs needs to be called into question: do they represent progress, or are they a mirage to block possible avenues of development? Currently existing NAPs have done little (yet) to ensure more effective protection in key policy areas, including trade and investment, state-owned enterprises, and particularly in relation to legislative developments and access to remedy. This contribution seeks to analyse the merits of developing NAPs, the importance of ensuring they become only the very first step towards a more effective protection of human rights, and to question whether their importance needs to be adjusted to what they really are: policy tools with limited effects and with a politically linked time frame.
Personnel Politics: Elections, Clientelistic Competition and Teacher Hiring in Indonesia
Authors: Pierskalla Jan H , Sacks Audrey 
Published: February 2019

AbstractWhat is the effect of increased electoral competition on patronage politics? If programmatic appeals are not credible, institutional reforms that move politics from an elite- to a mass-focused and more competitive environment increase patronage efforts. This leads to an overall surge and notable spike in discretionary state hiring in election years. The study tests this prediction in the context of Indonesia’s decentralized education sector. The authors exploit the exogenous phasing in and timing of elections in Indonesian districts for causal identification. They find evidence of election-related increases in the number of contract teachers on local payrolls and increases in civil service teacher certifications, which dramatically increases salaries. These effects are particularly pronounced for districts in which the former authoritarian ruling party is in competition with new entrants.

Published: February 2019

AbstractBackgroundSimulation-based training has a fundamental role in medical education as it allows the learner to gain experience managing emergencies in a safe, controlled environment.MethodsThis 1-day course consisted of eight high-fidelity simulation scenarios, followed by a video-assisted debrief focusing on the technical and non-technical (communication skills, teamwork, leadership and situational awareness) aspects of managing ENT and head and neck emergencies.ResultsEight courses have run since June 2014. Post-course questionnaires demonstrated that candidates’ confidence scores in managing airway and head and neck emergencies increased following completion of the course (p < 0.0001).ConclusionThis was the first fully immersive ENT simulation course developed in the region. The learning objectives for each scenario were mapped to the ENT Intercollegiate Surgical Curriculum Programme. Feedback from the course indicated a continued demand for this style of training, leading to its inclusion in the training calendar.
Developmental cascades to children's conduct problems: The role of prenatal substance use, socioeconomic adversity, maternal depression and sensitivity, and children's conscience

Published: February 2019

AbstractThis study investigated the longitudinal associations among prenatal substance use, socioeconomic adversity, parenting (maternal warmth, sensitivity, and harshness), children's self-regulation (internalization of rules and conscience), and conduct problems from infancy to middle childhood (Grade 2). Three competing conceptual models including cascade (indirect or mediated), additive (cumulative), and transactional (bidirectional) effects were tested and compared. The sample consisted of 216 low-income families (primary caretaker and children; 51% girls; 74% African American). Using a repeated-measures, multimethod, multi-informant design, a series of full panel models were specified. Findings primarily supported a developmental cascade model, and there was some support for additive effects. More specifically, maternal prenatal substance use and socioeconomic adversity in infancy were prospectively associated with lower levels of maternal sensitivity. Subsequently, lower maternal sensitivity was associated with decreases in children's conscience in early childhood, and in turn, lower conscience predicted increases in teacher-reported conduct problems in middle childhood. There was also a second pathway from sustained maternal depression (in infancy and toddlerhood) to early childhood conduct problems. These findings demonstrated how processes of risk and resilience collectively contributed to children's early onset conduct problems.
Caregiver–adolescent co-reminiscing and adolescents’ individual recollections of a devastating tornado: Associations with enduring posttraumatic stress symptoms

Published: February 2019

AbstractAlthough disaster-related posttraumatic stress symptoms (PTSS) typically decrease in intensity over time, some youth continue to report elevated levels of PTSS many years after the disaster. The current study examines two processes that may help to explain the link between disaster exposure and enduring PTSS: caregiver emotion socialization and youth recollection qualities. One hundred and twenty-two youth (ages 12 to 17) and their female caregivers who experienced an EF-4 tornado co-reminisced about the event, and adolescents provided independent recollections between 3 and 4 years after the tornado. Adolescent individual transcripts were coded for coherence and negative personal impact, qualities that have been found to contribute to meaning making. Parent–adolescent conversations were coded for caregiver egocentrism, a construct derived from the emotion socialization literature to reflect the extent to which the caregiver centered the conversation on her own emotions and experiences. Egocentrism predicted higher youth PTSS, and this association was mediated by the coherence of adolescents’ narratives. The association between coherence and PTSS was stronger for youth who focused more on the negative personal impacts of the tornado event during their recollections. Results suggest that enduring tornado-related PTSS may be influenced in part by the interplay of caregiver emotion socialization practices and youth recollection qualities.
The effectiveness of dietary workplace interventions: a systematic review of systematic reviews
Authors: Schliemann Désirée , Woodside Jayne V 
Published: February 2019

AbstractObjectiveTo summarise findings of systematic reviews that distinctively report dietary intervention components and their effects on diet-, health- and economic-related outcomes in the workplace setting.DesignMEDLINE, Embase, CINAHL, Web of Science, Cochrane Library and Google Scholar were searched in December 2014 and the search was updated in August 2017.ResultsThe search identified 1137 titles, of which nineteen systematic reviews from the initial search and two systematic reviews from the updated search met the inclusion criteria (twenty-one systematic reviews, published in twenty-two papers). Most systematic reviews were of moderate quality and focused on dietary behaviour change outcomes and some health-related biomarkers. Evidence was strongest for interventions to increase fruit and vegetable intake, reduce fat intake, aid weight loss and reduce cholesterol. Few reported workplace-related and evaluation outcomes.ConclusionsThese findings suggest that workplace dietary interventions can positively influence diet and health outcomes. Suggestions for effective interventions components have been made.
TOWARDS A NON-ARCHIMEDEAN ANALYTIC ANALOG OF THE BASS–QUILLEN CONJECTURE
Authors: Kerz Moritz , Saito Shuji , Tamme Georg 
Published: February 2019

We suggest an analog of the Bass–Quillen conjecture for smooth affinoid algebras over a complete non-archimedean field. We prove this in the rank-1 case, i.e. for the Picard group. For complete discretely valued fields and regular affinoid algebras that admit a regular model (automatic if the residue characteristic is zero) we prove a similar statement for the Grothendieck group of vector bundles$K_{0}$.
LOGIC FOR EXACT ENTAILMENT
Authors: FINE KIT , JAGO MARK 
Published: February 2019

AbstractAn exact truthmaker for A is a state which, as well as guaranteeing A’s truth, is wholly relevant to it. States with parts irrelevant to whether A is true do not count as exact truthmakers for A. Giving semantics in this way produces a very unusual consequence relation, on which conjunctions do not entail their conjuncts. This feature makes the resulting logic highly unusual. In this paper, we set out formal semantics for exact truthmaking and characterise the resulting notion of entailment, showing that it is compact and decidable. We then investigate the effect of various restrictions on the semantics. We also formulate a sequent-style proof system for exact entailment and give soundness and completeness results.
Entwicklung und erste Validierung eines Situational-Judgement-Instruments zur Erfassung von Kompetenzen im Bereich des Ressourcenmanagements (ReMI)

Published: February 2019

Zusammenfassung. Ein Studium stellt Lernende vor umfangreiche Herausforderungen im Bereich des selbstregulierten Lernens, insbesondere im Bereich des Ressourcenmanagements. Entsprechend sollte Ressourcenmanagement prädiktiv für Lernerfolg im Studium sein. Jedoch mangelt es bisher an validen Instrumenten zur Erfassung entsprechender Kompetenzen. Es wird daher ein neues Instrument vorgestellt, das Ressourcenmanagementkompetenzen in Form von konditionalem Strategiewissen als auch in Form von Defiziten bei der Strategieanwendung erfasst. Dieses Instrument wurde hinsichtlich seiner Validität mit einer Stichprobe von N = 198 Erstsemesterstudierenden überprüft. Konfirmatorische Faktorenanalysen bestätigen die theoretisch angenommene Faktorenstruktur. Zudem zeigen sich erwartungskonforme konvergente und diskriminante Korrelationen mit externen Kriterien. Prognostische Validität zeigt sich in der Form, dass Ressourcenmanagementkompetenzen, erfasst über das neue Instrument, Studienerfolg inkrementell zur Abiturnote und schlussfolgerndem Denken als Indikator für Intelligenz signifikant vorhersagen können.
Karriere-Ressourcen messen

Published: February 2019

Zusammenfassung. Die existierende Literatur schlägt eine Vielzahl von potentiellen Prädiktoren für Karriereerfolg vor, welche in ihrer Menge kaum auf eine ökonomische Art erhoben werden können. Um diesen Umstand anzugehen, haben Hirschi, Nagy, Baumeler, Johnston und Spurk (2018) den Karriere-Ressourcen Fragebogen (CRQ; Career Resources Questionnaire) entwickelt und in einer englischsprachigen Version validiert. Basierend auf einer Integration von theoretischer und metaanalytischer Forschung misst der Fragebogen 13 distinkte Faktoren, welche 4 übergeordnete Dimensionen repräsentieren: Wissen und Kompetenzen, Motivation, Umfeld und Aktivitäten bezüglich Karriere. In der vorliegenden Studie wird eine Validierung der deutschsprachigen Version mittels N = 1 666 Personen (Studierende und Berufstätige) vorgenommen. Die Ergebnisse bestätigen die Reliabilität sowie die Faktorstruktur des Fragebogens. Mittels Relative-Weight-Analysen konnte zudem die Wichtigkeit von verschiedenen Faktoren für unterschiedliche Arten von Karriereerfolg gezeigt werden. Das Messinstrument bietet Forschenden und Praktizierenden eine ökonomische, reliable und valide Möglichkeit, um Schlüsselfaktoren für Karriereerfolg zu erfassen.
