Abstract
The requirements for the performance of a ground-penetrating radar (GPR) system for detecting subsurface cavities are analyzed by numerical modeling of the GPR problem. The algorithm used to solve the forward GPR problem is approximated to a real experiment with regard to the design of the GPR system, the parameters of the source and receiver, and their position relative to the medium under study and its inhomogeneity. We calculated the spatiotemporal distribution of the field of the detected signal from a pulse source located at the interface between the medium and a cavity anomaly of a given geometry. The results were used to estimate the dynamic range of the GPR system necessary for determining the anomaly. We also performed GPR surveys of low-contrast inhomogeneities (cavities in mines) using GROT 12 GPR systems and analyzed the survey results by numerical modeling. It is shown that the GPR performance required to detect and locate inhomogeneities of interest at a certain sounding depth can be estimated in the experiment design phase.

Abstract
Fractures and vugs were used as the primary dolomite reservoir space in the study area, which improved the reservoir’s physical properties and influenced the distribution pattern of oil and water that were developed in the Upper Tenger Formation, Lower Cretaceous, Baiyinchagan sag, Erlian Basin. Based on the core observation data, thin slice analysis, and image logging, the cave-fractured reservoir was primarily developed in the actic region near the side of a depositional fault. Tectonic and diagenetic fractures were the primary types of fractures. High-angle tectonic fractures in the closure and open status were developed well in dolomitic mudstone, while a low-angle fracture and reticulate fractures were developed in the tectonic-hydrothermal hybrid process and were filled with hydrothermal minerals. The reservoir was located in low-lying land; therefore, detrital grain pressolution fractures were formed by burial diagenesis. Intergranular and intrangranular dissolved pores, which were formed by hydrothermal activity, were developed primarily in the highly dolomite lithology. According to the diagenesis temperature of dolomite from a carbon–oxygen isotope analysis, multiple hydrothermal fluid injection events occurred, and dolomitization ensued before massive hydrocarbon migration. The dissolution of organic acids formed by hydrocarbon charges after dolomitization and inorganic acid produced by burial diagenesis for soluble minerals effectively promoted the reservoir properties. Strong heterogeneity due to lithology and fracture–vug systems led to intricate oil–water relationships. Four statuses occurred, including cave-fracture oil, isolated oil, stored oil, isolated water, and stored water. The oil–water distribution patterns were established based on the core observation.

Authors: Kaplun V.B. 
Published: April 2018

Abstract
The paper describes the results of magnetotelluric sounding (MTS) carried out in the Zeya block of the Stanovoi megablock, in the area of its junction with the Aldan Shield. The border between them runs along the Stanovoi fault. Based on the results of interpretation of MTS curves and the gravity, magnetic, and geological data, geological/geophysical sections have been constructed to a depth of 7 km along two ~ 20 km long profiles running across the Stanovoi fault. About 1 km thick and approximately 2 km long conductivity zone has been distinguished beneath the Okonon plateau of Quaternary basalts with electrical resistivity of &lt; 100 Ohm·m. This anomaly is associated with ore mineralization in Early Proterozoic gabbro intrusion. A 3D density modeling was performed. High-density bodies of NW strike dip to the northeast to a depth of 25 km in the area of the Okonon basalt plateau.
WHAT EXPLAINS SPECIALTY COFFEE QUALITY SCORES AND PRICES: A CASE STUDY FROM THE CUP OF EXCELLENCE PROGRAM
Authors: TRAORE TOGO M. , WILSON NORBERT L.W. , FIELDS DEACUE 
Published: April 2018

AbstractThis study investigates the effects of material and symbolic quality attributes on the Cup of Excellence specialty coffee quality scores and prices. The estimates from the quality score equations suggest that material attributes are important determinants, but symbolic attributes have a greater explanatory power. The hedonic price estimations show that specialty coffee prices are mainly determined by symbolic attributes and market conditions such as the number of coffees in the auction. Overall, the study reveals that fruity, floral, sweet, spice, and sour acid are cuppers' and buyers' most favorite coffee flavors and aromas.

Published: April 2018

We hypothesized that a computerized clinical decision support tool for Clostridium difficile testing would reduce unnecessary inpatient tests, resulting in fewer laboratory-identified events. Census-adjusted interrupted time-series analyses demonstrated significant reductions of 41% fewer tests and 31% fewer hospital-onset C. difficile infection laboratory-identified events following this intervention.Infect Control Hosp Epidemiol 2018;39:737–740
OBEAH, VAGRANCY, AND THE BOUNDARIES OF RELIGIOUS FREEDOM: ANALYZING THE PROSCRIPTION OF “PRETENDING TO POSSESS SUPERNATURAL POWERS” IN THE ANGLOPHONE CARIBBEAN
Authors: Boaz Danielle N. 
Published: April 2018

AbstractThe practice of obeah, a term used to refer to a variety of African derived spiritual practices, remains proscribed in at least fourteen countries or territories in the Anglophone Caribbean today. This article examines the historical development of these laws and the significance of the continued prohibition of obeah. Although obeah laws were initially modeled on British statutes banning vagrancy and witchcraft, and were passed during a period when it was common for nations in the Western Hemisphere to prohibit the practice of African diaspora faiths, these statutes stand in stark contrast to the religious freedoms guaranteed in other parts of the Atlantic world in the twenty-first century. Obeah laws proscribe the mere performance of certain spiritual rituals, while other countries modified their policies in the mid-twentieth century to require evidence of intentional fraud and financial gain to convict occult practitioners. This article links the continued proscription of obeah to nineteenth century assertions that African peoples were animists and fetishists, as well as to long-standing hierarchies in the Western world placing theistic religions above those centered on spirit conjuring, divination, and the manipulation of supernatural forces.

Published: April 2018

ABSTRACTCalving plays a key role in the recent rapid retreat of glaciers around the world. However, many processes related to calving are poorly understood since direct observations are scarce and challenging to obtain. When calving occurs at a glacier front, surface-water waves arise over the ocean or a lake in front of glaciers. To study calving processes from these surface waves, we performed field observations at Glaciar Perito Moreno, Patagonia. We synchronized time-lapse photography and surface waves record to confirm that glacier calving produces distinct waves compared with local noise. A total of 1074 calving events were observed over the course of 39 d. During austral summer, calving occurred twice more frequently than in spring. The cumulative distribution of calving-interevent time interval followed exponential model, implying random occurrence of events in time. We further investigated wave properties and found that source-to-sensor distance can be estimated from wave dispersion within ~20% error. We also found that waves produced by different calving types showed similar spectra in the same frequency range between 0.05–0.2 Hz, and that the amplitude of surface waves increased with the size of calving. This study demonstrates the potential of surface-wave monitoring for understanding calving processes.
How Domestic Firms Absorb Spillovers: A Routine-Based Model of Absorptive Capacity View
Authors: Tzeng Cheng-Hua 
Published: April 2018

ABSTRACTExtant spillover literature explains domestic firms' productivity change mainly by the presence and attributes of foreign direct investment. In contrary, this paper, by adopting a routine-based model of absorptive capacity, intends to explore how domestic firms absorb spillovers over time. Based on a qualitative study of a domestic firm in China's silicone adhesive industry, the findings show that unbounded by geographical constraints, domestic firms enact their external absorptive capacity routines to actively search for spillovers from multinational enterprises (MNEs) at both national and international levels. Moreover, rather than searching for what is available, domestic firms are selective for spillovers that are coherent with their business strategies. The most unexpected finding is that domestic firms diligently acquire spillovers from MNEs and from local competitors in combination. Spillovers acquired from local competitors are used to increase the inferential accuracy of spillovers acquired from MNEs about strategic successes. Further, instead of absorbing spillovers from MNEs which pose moderate technology gaps, domestic firms target at MNEs which exhibit wider technology gaps, and undertake organizational learning and develop complementary assets to enhance their internal absorptive capacity routines. Socially enabling mechanisms are found to facilitate domestic firms' absorption of spillovers by employee turnover.

AbstractThe aim of this study is to analyse the efficacy rate of folate for the treatment of hyperhomocysteinaemia (HHcy) and to explore how folate metabolism-related gene polymorphisms change its efficacy. This study also explored the effects of gene–gene and gene–environment interactions on the efficacy of folate. A prospective cohort study enrolling HHcy patients was performed. The subjects were treated with oral folate (5 mg/d) for 90 d. We analysed the efficacy rate of folate for the treatment of HHcy by measuring homocysteine (Hcy) levels after treatment. Unconditioned logistic regression was conducted to analyse the association between SNP and the efficacy of folic acid therapy for HHcy. The efficacy rate of folate therapy for HHcy was 56·41 %. The MTHFR rs1801133 CT genotype, TT genotype and T allele; the MTHFR rs1801131 AC genotype, CC genotype and C allele; the MTRR rs1801394 GA genotype, GG genotype and G allele; and the MTRR rs162036 AG genotype and AG+GG genotypes were associated with the efficacy of folic acid therapy for HHcy (P<0·05). No association was seen between other SNP and the efficacy of folic acid. The optimal model of gene–gene interactions was a two-factor interaction model including rs1801133 and rs1801394. The optimal model of gene–environment interaction was a three-factor interaction model including history of hypertension, history of CHD and rs1801133. Folate supplementation can effectively decrease Hcy level. However, almost half of HHcy patients failed to reach the normal range. The efficacy of folate therapy may be genetically regulated.

AbstractThis study systematised and synthesised the results of observational studies that were aimed at supporting the association between dietary patterns and cardiometabolic risk (CMR) factors among adolescents. Relevant scientific articles were searched in PUBMED, EMBASE, SCIENCE DIRECT, LILACS, WEB OF SCIENCE and SCOPUS. Observational studies that included the measurement of any CMR factor in healthy adolescents and dietary patterns were included. The search strategy retained nineteen articles for qualitative analysis. Among retained articles, the effects of dietary pattern on the means of BMI (n 18), waist circumference (WC) (n 9), systolic blood pressure (n 7), diastolic blood pressure (n 6), blood glucose (n 5) and lipid profile (n 5) were examined. Systematised evidence showed that an unhealthy dietary pattern appears to be associated with poor mean values of CMR factors among adolescents. However, evidence of a protective effect of healthier dietary patterns in this group remains unclear. Considering the number of studies with available information, a meta-analysis of anthropometric measures showed that dietary patterns characterised by the highest intake of unhealthy foods resulted in a higher mean BMI (0·57 kg/m²; 95 % CI 0·51, 0·63) and WC (0·57 cm; 95 % CI 0·47, 0·67) compared with low intake of unhealthy foods. Controversially, patterns characterised by a low intake of healthy foods were associated with a lower mean BMI (−0·41 kg/m²; 95 % CI −0·46,−0·36) and WC (−0·43 cm; 95 % CI −0·52,−0·33). An unhealthy dietary pattern may influence markers of CMR among adolescents, but considering the small number and limitations of the studies included, further studies are warranted to strengthen the evidence of this relation.
Judicial Support for Arbitration in Nigeria: On Interpretation of Aspects of Nigeria's Arbitration and Conciliation Act
Authors: Bamodu ’Gbenga 
Published: April 2018

AbstractThe quality of judicial support and respect for the principle of minimum intervention are crucial factors in assessing whether a jurisdiction is attractive for arbitration. While there have been efforts to present Nigeria as an arbitration-friendly jurisdiction and an attractive arbitration venue, questions remain about the adequacy, effectiveness and certainty of legal rules concerning arbitration in Nigeria. There are also questions about the quality and efficiency of judicial support for arbitration in light of some judicial decisions affecting arbitration that have generated controversy. Through a careful analysis of key statutory provisions and judicial decisions, this article analyses support for arbitration in Nigeria in respect of selected topics, including party autonomy, upholding arbitration agreements (especially concerning the stay of judicial proceedings), the stay of arbitration proceedings and third party intervention. The article identifies scope for improvement in statutory and judicial approaches. It makes suggestions concerning both judicial approaches and reform of the statutory regimes.
Gametogony ofEimeria macusaniensisGuerrero, Hernandez, Bazalar and Alva, 1971 in llama (Lama glama)
Authors: Dubey J P. 
Published: April 2018

AbstractCamelids (llama, alpaca, vicunãs, guanacos) are important for the economy of South America andEimeriainfections are an important cause of mortality in camelids. Of the six species ofEimeriain camelids,Eimeria macusaniensis, considered the most pathogenic, is distinctive; its oocysts are the largest among allEimeriaspecies in animals, its prepatent period is more than 1 month, and its oocysts have been found in mummies from prehistoric times. Although,E. macusaniensisgametogonic stages are found associated with enteritis in naturally infected camelids, the schizogonic stages are unknown and clinical disease has been reported in some camelids with no oocysts in feces. Described herein are morphological details of gametogonic development and oocyst formation ofE. macusaniensisin a naturally infected llama (Lama lama), solely infected with this parasite. Microgamonts, macrogamonts and oocysts were located in large (up to 300µm diameter) parasitophorous vacuoles of enterocytes in the ileum. Schizonts were not found. Review of previous reports suggests that multinucleated microgamonts have been mistaken for schizonts. Gametogonic development described in the present study can serve as a guide for differential diagnosis ofEimeriaspecies in the histological sections of intestines.
PREOPERATIVE MAGNETIC RESONANCE IMAGING DIAGNOSTIC FEATURES OF UTERINE LEIOMYOSARCOMAS: A SYSTEMATIC REVIEW
Authors: Kaganov Helen , Ades Alex , Fraser David Stuart 
Published: April 2018

Objectives:There are no current established pathognomonic diagnostic features for uterine leiomyosarcomas in the pre- or perioperative setting. Recent inadvertent upstaging of this rare malignancy during laparoscopic morcellation of a presumed fibroid has prompted widespread debate among clinicians regarding the safety of current surgical techniques for management of fibroids. This study aims to conduct a systematic review investigating significant diagnostic features in magnetic resonance imaging (MRI) of uterine leiomyosarcomas.Methods:A comprehensive database search was conducted guided by PRISMA recommendations for peer-reviewed publications to November 2017. Parameters available in MRI were compared for reliability and accuracy of diagnosis of leiomyosarcomas. A decision tree algorithm classifier model was constructed to investigate whether T1 and T2 MRI signal intensities are useful indicators.Results:Nine eligible studies were identified for analysis. There appears to be a significant relationship between histopathological type and T1 and T2 intensity signals (p< .05). A decision tree model analyzing T1 and T2 signal intensity readings supports this trend, with a diagnostic specificity of 77.78 percent for uterine leiomyosarcomas. The apparent diffusion coefficient (ADC) values were not observed to have a significant relationship with tumor pathology (p= .18).Conclusions:Various studies have investigated pre- and perioperative techniques in differentiating uterine leiomyosarcoma from benign fibroids. Given the rarity of the malignancy and lack of pathognomonic diagnostic parameters, there is difficulty in establishing definitive criteria. A decision tree model is proposed to aid diagnosis based on MRI signal intensities.
SUCCESSFUL IMPLEMENTATION OF LEAN AS A MANAGERIAL PRINCIPLE IN HEALTH CARE: A CONCEPTUAL ANALYSIS FROM SYSTEMATIC LITERATURE REVIEW
Authors: Maijala Riikka , Eloranta Sini , Reunanen Tero , Ikonen Tuija S. 
Published: April 2018

Purpose:The aim of this study was to identify and analyze the characteristics of leadership and management associated with a successful Lean thinking adaptation in healthcare.Design:A systematic literature review was undertaken using electronic databases: PubMed, PubMed Systematic Review, ABI/INFORM, Business Source Complete, Emerald, JBI, and Cinahl. Inclusion criteria were: (i) a description of Lean management or leadership in health care, (ii) a reference to Lean thinking, (iii) a peer-reviewed original research article or a literature review, and (iv) a full text article available in English. Among the 1,754 peer-reviewed articles identified, nine original articles and three systematic reviews met the inclusion criteria. Data on informants, methods, and settings were extracted and collated. Content analysis was used to conduct a review of the nine original studies describing and analyzing the success factors of Lean adaptation. The characteristics of leadership and management were analyzed by using the concept of a managerial windshield that divides leadership and management into four ontological dimensions: activities, style, focus, and purpose, each with typical developmental stages of skills and capabilities. The current study has some limitations: some papers from the journals not indexed in the searched databases may have been overlooked and the literature searches were carried out only for a 5-year period.Findings:Considering the results using the windshield concept emphasizes the philosophy, principles, and tools of Lean thinking. Lean leadership and management factors in health care were mainly conceptualized as skills and capabilities such as problem solving, making changes occur, empowering, communicating, coaching, supporting, facilitating, being democratic, organizational learning, and organizational success, all of which represented middle-stage or advanced managerial skills and capabilities.Practical Implications:A conceptual analysis of systematically reviewed studies of Lean leadership and management point to certain traits as being typical when adapting Lean thinking to health care. The concept of a managerial windshield is useful when categorizing and analyzing essential managerial skills and capabilities for Lean implementation. Findings are beneficial when learning and educating the skills required for Lean transformation in healthcare organizations.
Domestic Flying Geese: Industrial Transfer and Delayed Policy Diffusion in China
Authors: Ang Yuen Yuen 
Published: April 2018

AbstractThis study illuminates the important yet under-studied phenomenon of industrial transfer in China: the migration of capital and investment from wealthy coastal areas into poorer central and western provinces, beginning in the 2000s. By 2015, the value of domestic investment in five central provinces alone was 2.5 times that of foreign investment throughout China. Compared to the original “flying geese” model of tiered production in Asia, China's experience is distinct in three ways: (1) industrial transfer occurred domestically, rather than across nations; (2) sub-national transfer followed cross-national transfer; and (3) industrial migration is accompanied by a delayed replication of government policies and practices. While coastal locales today resolve to expel low-end industries, inland governments cannot afford to be selective and have only recently adopted the aggressive investment promotion tactics that coastal cities abandoned years ago. Policy diffusion is delayed as policy adoption depends on economic conditions, which vary widely across China and change over time.
Explaining the Trump Vote: The Effect of Racist Resentment and Anti-Immigrant Sentiments
Authors: Hooghe Marc , Dassonneville Ruth 
Published: April 2018

ABSTRACTThe campaign leading to the 2016 US presidential election included a number of unconventional forms of campaign rhetoric. In earlier analyses, it was claimed that the Trump victory could be seen as a form of protest voting. This article analyzes the determinants of voters’ choices to investigate the validity of this claim. Based on a sample of the 2016 Cooperative Congressional Election Survey, our analyses suggest that a Trump vote cannot be explained by a lack of trust in politics or low levels of satisfaction with democracy, as would be assumed given the extant literature on protest voting. However, indicators of racist resentment and anti-immigrant sentiments proved to be important determinants of a Trump vote—even when controlling for more traditional vote-choice determinants. Despite ongoing discussion about the empirical validity of racist resentment and anti-immigrant sentiments, both concepts proved to be roughly equally powerful in explaining a Trump vote.
