Authors: Hua Nan , Li Bin , Zhang Tingting(Christina) 
Published: April 2020

Purpose
The purpose of this study is to present a holistic literature review on crime research in the hospitality and tourism field.

Design/methodology/approach
This literature review included 109 crime-related academic papers in seven primary sources, namely, ScienceDirect, EBSCOhost’s hospitality and tourism complete, Emerald Management eJournals, Sage Journals, Google Scholar, Scopus and Web of Science.

Findings
From the exploration and synthesis of 109 articles, the following categories of crime research in the hospitality and tourism field emerged as follows: classification of crime research in the hospitality and tourism field; diversity of tourists, crime and risk perceptions; the impacts of crime on the hospitality and tourism industry; and crime control from stakeholders’ papers. In addition, this study advances crime research by proposing six research priorities for future investigation.

Practical implications
Tourism stakeholders are advised to achieve better cooperation in crime control under the guidance of the crime prevention model. High-technology tools are encouraged to be applied to detect and track criminal activities. Meanwhile, diverse applications of the media should be used as useful tools to control criminal activities in the hospitality and tourism industry.

Originality/value
This paper fills a gap by presenting the first comprehensive overview of crime research in the hospitality and tourism field in the past few decades and proposing six priorities for this research stream.

Authors: Borg Ellul Duncan , Wond Tracey 
Published: April 2020

PurposeThe present study aims to conduct a critical review of an existing set of practices within the Maltese public sector.Design/methodology/approachThis study is based on interpretivism (people-centred approach) embedded in a pragmatic research paradigm (the use of mixed methods).FindingsMisconceptions about the role and practice of executive coaching in Malta relates to the similar roles ascribed to mentoring, supervision, therapy, consultation, coaching, audit and watchdog under the misnomer of “coaching”.Research limitations/implicationsThe main contribution of this research is to the community of professional practitioners as well as to the Maltese central government to improve managerial effectiveness in the Maltese public sector with several endorsed policy-level recommendations presented in the study.Practical implicationsThe results suggest a restructuring of a well-defined, structures, systems and dynamics within the Maltese public administration, the ability by senior management including senior public officers (SPOs) to recognise high-potential talents, the need to expand leadership capacity, the establishment of a professional coaching body and a national coaching network framework.Originality/valueTo the best of the authors’ knowledge, this is the first study that investigates the role and impact of executive coaching in the Maltese public sector using quantitative and qualitative empirical data.
Envisioning reciprocal and sustainable HBCU-LIS pipeline partnerships
Authors: Ndumu Ana V. , Rollins Tina 
Published: April 2020

Purpose
After the closing of four of the five historically Black college and university (HBCU)–based library and information science (LIS) graduate programs (leaving only that of North Carolina Central University), there is a need to revitalize HBCU-LIS degree program pathways to increase racial diversity in LIS education.

Design/methodology/approach
This mixed-methods study entails survey and interview research with HBCU librarians. The researchers explored participants’ professional experiences and perspectives on creating partnerships between HBCU institutions and LIS graduate programs.

Findings
Participants demonstrated substantial experience, expressed high levels of job satisfaction, viewed pipeline programs favorably and believed that LIS can be strengthened through the inclusion of HBCU educational practices and students.

Practical implications
This study provides recommendations and a model for forging culturally competent and reciprocal HBCU–LIS degree program partnerships.

Social implications
Community-led knowledge of HBCUs can disrupt rescue and deficiency narratives of these institutions. Such prejudices are detrimental to HBCU-LIS degree program partnerships.

Originality/value
Past HBCU-LIS degree program pipeline partnerships did not culminate in research or published best practices. This paper presents literature-derived and community-sourced guidelines along with a model for future initiatives.
Momentum return volatility, uncertainty, and energy prices: evidence from major international equity markets
Authors: Spyrou Spyros 
Published: April 2020

PurposeThis paper examines the impact of macroeconomic and risk factors on the profitability and volatility of professional momentum portfolios for the US, the UK, Japan and Germany, for the period 1998–2018. Many of the factors employed, such as energy price changes and economic policy uncertainty, have been largely neglected in the relevant literature.Design/methodology/approachRegression analysis, VECTOR AUTOREGRESSION (VAR), Panel-VAR, Variance Decomposition AnalysisFindingsThe results indicate that, since the financial crises in the US and the EU, energy prices and economic-policy uncertainty have become important return determinants, along with market-related uncertainty that seems to have a stable impact over time, especially for the U.S. and U.K. portfolios.Research limitations/implicationsEconomic policy uncertainty significantly affects contemporaneous momentum returns in the US, UK and Japan, mainly between 2007 and 2018, while market-related uncertainty affects all markets during all subperiods. In addition, the variance of market-related uncertainty (VIX) explains a large percentage of the variance in the momentum returns for the US, UK and Germany.Practical implicationsThe main implication of the findings for portfolio managers is that a manager may increase (decrease) exposure to the momentum factor during optimistic (pessimistic) periods and during periods of rising energy prices (high economic policy and market-related uncertainty).Originality/valueThe paper examines the impact of factors, such as energy prices and economic policy uncertainty, which have been largely neglected in the relevant literature on the possible drivers of the momentum strategies. It employs professional portfolios that are often used in practice as benchmark indexes.

Published: April 2020

SummaryFetal and neonatal alloimmune thrombocytopenia (FNAIT) is the consequence of platelet destruction by maternal alloantibodies against fetal human platelet antigens (HPA). This may result in intracranial haemorrhages (ICH) or even fetal death. Currently, fetal HPA genotyping is performed using invasive procedures. Here, we carried out a proof‐of‐concept study for non‐invasive prenatal diagnosis of fetal platelet genotyping in four HPA systems (HPA‐1, ‐3, ‐5 and‐15) by droplet digital polymerase chain reaction (ddPCR) using cell‐free DNA extracts from the plasma of 47 pregnant women with suspected, or history of, FNAIT. Results showed that 74% (35/47) of pregnant women presented incompatibility in at least one HPA system, and 38% (18/47) of cases presented HPA‐1 incompatibility, including nine women with multiple incompatibilities. ICH occurred in one case of profound fetal thrombocytopenia with HPA‐15 incompatibility, confirming the need for non‐invasive prenatal genotyping in systems other than HPA‐1. Fetal HPA genotypes predicted by ddPCR were confirmed in all FNAIT cases after amniocentesis or delivery. Fetal HPA genotyping on maternal plasma based on ddPCR is a fast, safe and reliable non‐invasive method. This technique will be useful for the early identification of pregnancies at high risk of FNAIT requiring antenatal management to minimize the risk of fetal/neonatal haemorrhage.

Published: April 2020

Pada bencana Lumpur Sidoarjo, pembangunan tanggul merupakan salah satu penanggulangan untuk membatasi dampak terjadinya Lumpur Sidoarjo. Tanggul bagian utara Lumpur Sidoarjo merupakan salah satu segmen yang pernah mengalami keruntuhan. Sebenarnya risiko keruntuhan tanggul dapat diminimalkan dengan mengevaluasi faktor keamanan (FK) dari segmen tanggul yang rutin. Penelitian ini bertujuan untuk mengevaluasi FK di tanggul utara dan menentukan rekomendasi peningkatan FK. Metode penelitian mencakup analisis evaluasi stabilitas lereng dengan menggunakan parameter geometri lereng tanggul dari lapangan dan dari hasil uji laboratorium. Daerah penelitian tersusun dari satuan tanah asli berupa endapan aluvium berukuran pasir-lempung dan satuan tanah urugan berupa material pasir-kerakal. Pada kondisi tampungan normal dan tanpa gempa, FK di bagian hilir tanggul P74 dan P75 tergolong aman (1,572 dan 1,580). Tanggul P79 tergolong rentan karena memiliki FK 0,840 dengan kondisi tampungan normal dan tanpa gempa. Rekomendasi untuk peningkatan nilai FK adalah pemadatan tanah, membuat kawat pada bagian hulu, pelandaian lereng tubuh tanggul dan penutupan rekahan, serta pembuataan drainase pada hilir tanggul.
Finite-Size Scaling of Typicality-Based Estimates
Authors: Schnack Jürgen , Richter Johannes , Heitmann Tjark , Richter Jonas , Steinigeweg Robin 
Published: April 2020

Abstract
According to the concept of typicality, an ensemble average can be accurately approximated by an expectation value with respect to a single pure state drawn at random from a high-dimensional Hilbert space. This random-vector approximation, or trace estimator, provides a powerful approach to, e.g. thermodynamic quantities for systems with large Hilbert-space sizes, which usually cannot be treated exactly, analytically or numerically. Here, we discuss the finite-size scaling of the accuracy of such trace estimators from two perspectives. First, we study the full probability distribution of random-vector expectation values and, second, the full temperature dependence of the standard deviation. With the help of numerical examples, we find pronounced Gaussian probability distributions and the expected decrease of the standard deviation with system size, at least above certain system-specific temperatures. Below and in particular for temperatures smaller than the excitation gap, simple rules are not available.

Published: April 2020

Abstract
Background: There is a dearth of literature on predictive models estimating under-five mortality risk in Ethiopia. In this study, we develop a spatial map and predictive models to predict the sociodemographic determinants of under-five mortality in Ethiopia. Methods: The study data were drawn from the 2016 Ethiopian Demographic and Health Survey. We used three predictive models to predict under-five mortality within this sample. The three techniques are random forests, logistic regression, and k-nearest neighbors For each model, measures of model accuracy and Receiver Operating Characteristic curves are used to evaluate the predictive power of each model. Results: There are considerable regional variations in under-five mortality rates in Ethiopia. The under-five mortality prediction ability was found to be moderate to low for the models considered, with the random forest model showing the best performance. Maternal age at birth, sex of a child, previous birth interval, water source, health facility delivery services, antenatal and post-natal care checkups, breastfeeding behavior and household size have been found to be significantly associated with under-five mortality in Ethiopia. Conclusions: The random forest machine learning algorithm produces a higher predictive power for under-five mortality risk factors for the study sample. There is a need to improve the quality and access to health care services to enhance childhood survival chances in the country.

Abstract
Background: Endometritis adversely affects the ability of cattle to reproduce, and significantly reduces milk production. Consequently, it has great influence on the economic value of dairy cows. The endometrium is mainly composed of epithelial and stromal cells and they produce the first immune response to invading pathogens. Epithelial cells are the first cellular barrier through which bacteria enter the uterine endometrium. However, most of the epithelial cells are disrupted and stromal cells are exposed to an inflammatory environment when endometritis occurs, especially postpartum. A loss of the protective epithelium allows bacteria or toxins to access the underlying stromal cells. The activation of Toll-like receptor（TLRs）on stromal cells induces increased production of cytokines. Understanding the genome-wide characterization of the bovine endometritis will be beneficial for prevention and treatment of endometritis. In this study, whole-transcriptomic gene changes in bovine stromal cells treated with LPS were compared with those treated with PBS (control group) and were analyzed by RNA sequencing (RNA-seq). This was done in a cell culture model in vitro.Results: Compared with the control group, a total of 366 differentially expressed genes (DEGs) were identified in LPS-induced group (234 upregulated and 132 downregulated genes), with an adjusted P-value＜0.05 by DESeq. Gene ontology (GO) enrichment analysis revealed DEGs were most enriched in lymphocyte activation, interleukin-1 receptor binding, regulation of cell activation, and lymphocyte-activated interleukin-12 production. Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analysis revealed DEGs were most enriched in TNF signaling pathway, Toll-like receptor signaling pathway, cytokine-cytokine receptor interaction, nucleotide-binding oligomerization domain-like (NOD-like) receptor signaling pathway, NF-κB signaling pathway, and chemokine signaling pathway.Conclusion: The results of this study unraveled bovine endometrial stromal cells affected with LPS transcriptome profile alterations，which may have a significant effect on the treatment inflammation by comprehending molecular mechanisms and authenticating unique genes related to endometritis.
NCAM and attached polysialic acid affect behaviors of breast epithelial cells through differential signaling pathways
Authors: Cao Lin , Wang Xin , Yang Juhong , Guo Jia , Li Xiang , Yang Xiaomin , Tan Zengqi , Guan Feng 
Published: April 2020

Abstract

Background
Neural cell adhesion molecule (NCAM), a common mammalian cell surface glycoprotein, is the major substrate of polysialic acid (polySia). Polysialylated NCAM occurs in many types of cancer, but rarely in normal adult tissues. Epithelial-mesenchymal transition (EMT) is an important process contributing to tumor metastasis. The functional role of NCAM hypersialylation in EMT is unclear.
Method
Expression of NCAM and polysialylated NCAM in breast cancer progression were evaluated by western blot (WB), immunohistochemistry, semi-quantitative PCR and immunoprecipitation (IP). Overexpression of NCAM-140 and ST8SiaII were performed to assess the functional role of NCAM hypersialylation by liposome transfection. Cell proliferation ability was investigated with MTT assay. Transwell and wound closure assay were conducted to evaluate cell migratory ability. Phagokinetic gold sol assay and cell adhesion assay were performed to assess cell motility ability and cell adhesion ability, respectively. Furthermore, WB and IP were used to reveal the activated signaling pathway.
Results
The present study indicates that NCAM and attached polysialic acid affect behaviors of breast epithelial cells through differential signaling pathways, based on the following observations: (i) NCAM and polysialylated NCAM were aberrantly regulated in breast cancer cells; (ii) NCAM and polysialylated NCAM expression were upregulated in normal breast epithelial cells undergoing EMT; (iii) NCAM overexpression induced EMT in breast epithelial cells; (iv) NCAM promoted cell proliferation and migration through activation of a β-catenin/slug signaling pathway; (v) modification of polySia attached to NCAM inhibited cell adhesion and promoted cell motility through activation of an EGFR/STAT3 pathway.
Conclusion
This study demonstrates that NCAM and polysialylated NCAM facilitate different signaling pathway and affect different cell behaviors. Switching between the NCAM-mediated pathways appeared to depend on polySia decoration.

Published: April 2020

Abstract
Background Lung cancer is one of the most frequently fatal cancers. The microRNA-21 (miR-21) has a known oncogenic function on immune cells in tumors, but its biological role and clinical significance in immunosuppression of lung cancer remains largely enigmatic. Our study aims to explore the role and molecular mechanisms of miR-21 in lung cancer. Methods We observed that miR-21 and YAP were highly expressed, while RUNX1 was poorly expressed in lung cancer tissues and cell lines. The loss- and gain- function approaches were performed to determine the roles of miR-21, RUNX1 or YAP in the immunosuppressive ability of myeloid-derived suppressor cells (MDSCs) in lung cancer. Results MiR-21 inhibition, YAP knockdown or RUNX1 overexpression reduced the proportion of MDSCs in lung cancer tissue and peripheral blood, but increased the proportion of T helper (Th) and CTL. Furthermore, miR-21 inhibition, YAP knockdown or RUNX1 overexpression increased apoptosis of MDSCs, more cells at G0/G1 phase, fewer cells at G2/M phase, but reduced IL-10, TGF-β and GM-CSF levels. The effect of miR-21 and RUNX1 on tumor growth was verified by xenograft tumors in nude mice. Conclusions Taken together, miR-21 upregulates YAP expression by inhibiting RUNX1 and consequently promotes the immunosuppressive ability of MDSCs against lung cancer.

Published: April 2020

Abstract The possibility of growing bulk (more than 7 μm thick) epitaxial semipolar AlN films on Si(001) and hybrid SiC/Si(001) substrates without cracks has been investigated. It is found that an AlN layer grown on the Si substrate is extended, whereas an AlN layer grown on the hybrid SiC/Si substrate is compressed. The limiting (critical) thickness of the semipolar AlN layer on the Si(001) substrate is determined to be ~7.5 μm. When the film thickness exceeds this value, an ensemble of cracks is formed in the film, leading to its total cracking and exfoliation from the substrate. The semipolar epitaxial AlN films with a thickness of more than 40 μm are grown on hybrid SiC/Si substrates without cracking and exfoliation from the substrate.

Published: April 2020

resumenEn este trabajo se evalúa críticamente el papel de la Teoría de las definiciones implícitas (y en concreto la teoría de boghossian) en la resolución de dos problemas en torno al conocimiento de la lógica: el problema de la explicación (explicar cómo obtenemos creencias sobre nuestras reglas de inferencia), y el problema de la justificación (justificar que nuestras creencias así obtenidas son conocimiento). Se fijan cinco resultados a alcanzar: aprioricidad, factualismo, normatividad, aplicabilidad y no circularidad viciosa. Se argumentará que, aunque dichos resultados se pueden alcanzar respecto al problema de la explciación, no se evita circularidad viciosa en el problema de la justificaciónPALABRAS CLAVELÓGICA, CONOCIMIENTO, DEFINICIÓN IMPLÍCITA, CIRCULARIDADABSTRACTThis paper examines the rol of implicit Definitions Theory (specially Boghossian's theory) in the solution of two related problems about the status of logical knowledge: the explanation problem (how do we obtain beliefs concerning our rules of inference) and the justification problem (how do we know our beliefs concerning rules of inferences are justified). Five goals are assigned to the Implicit Definition Theory: apriocism, factualism, normativity, aplicability and not vicious circularity. it will be argued that these five goals are reached for the explanation problem, but nt for the justification problem.
