The “Gospel” of Pentecostalism and Entrepreneurship
Authors: Ojo Sanya
Published: March 2017

Sieving through the avalanche of dissertations on the Pentecostal movements this chapter attempts to analyze the African Pentecostalism's structural arrangement to generate a deeper understanding of its operations and how the movement is re-inventing itself in contemporary epoch. This was done by appraising in-depth knowledge in concrete terms rather than in abstraction through the combination of notions of the market, entrepreneurship, diaspora, and development. Thus, the chapter develops a new sociological understanding of the differences and similarities between religion and the market in ethnic/diaspora entrepreneurship market space. It argues that the success of African Pentecostalism, both in Africa and the diaspora, is predicated on its ability to smoothly connect the past with the present. Whilst synthesis of African culture in the movement's liturgy is a proficient engagement with the past, inculcating the efficiency ethos of the market economy in its operations signifies a commitment to the present.

This chapter describes the overview of entrepreneurship; corporate entrepreneurship and sustainable entrepreneurship; entrepreneurship and pro-market institutions; entrepreneurship, technological innovation, and Intellectual Property Rights (IPRs); the important aspects of diaspora entrepreneurship; entrepreneurship education, knowledge transfer, and technology transfer; and migration, employment, brain drain, and brain gain. The objectives of industrial development, regional growth, and employment generation depend on entrepreneurial development concerning entrepreneurship and diaspora entrepreneurship. Entrepreneurs and diaspora entrepreneurs play the crucial roles in accelerating the pace of economic development of countries by discovering the new uses of available resources and maximizing their utilization in global business. The works of entrepreneurs and diaspora entrepreneurs involve the utilization of managerial skills which they develop while planning, organizing, staffing, directing, controlling, and coordinating the activities of business.
Role of Entrepreneurship in Networked Indian Economy
Authors: Baporikar Neeta
Published: March 2017

Historically, all societies may have a constant supply of entrepreneurial activity, but that activity is distributed unevenly. Urban areas are favourable for innovative entrepreneurship, as a result of economies of density and the opportunities created by the city as a nucleus of a broader network. Thus, a modem entrepreneur tends to become increasingly a network operator and manager. The purpose of this chapter is to contribute to our understanding on entrepreneurship in networked economy of India; thereto the literature is summarized from the perspective of geographical seedbed conditions and network constellations. It focuses on the role played by small firms and entrepreneurship. The constraints are identified, and the areas that need action are highlighted. It is also suggested that in the age of liberalization and globalization, any attempt at creation of a competitive environment in the country would need to explicitly note the emerging global production and knowledge networks.
Diaspora and Transnational Entrepreneurship
Authors: Ojo Sanya , Nwankwo Sonny
Published: March 2017

The dynamic development in the field of Diaspora and Transnational entrepreneurship reveals a wide range of challenges and perspectives. These intensely tense up ‘conventional wisdom', stretch knowledge frontiers, and simultaneously expose fundamental paradoxes in the characterization of ethnic minorities' diaspora and transnational groups in the context of their entrepreneurship. Prior efforts at researching and advancing knowledge in this sphere have been hugely complicated, not less by the problematic of nomenclature but by researchers' application of terms. Against this background, this chapter aims to expand current understandings on the dialectic, dilemma, and paradoxical signals emitted by the events of diaspora and transnational entrepreneurship's economic activities both theoretically and practically. The significance resides in its capacity to enlarge our understanding of the dynamic process of individual agency in cross-border entrepreneurial relations.
Social Entrepreneurship and Social Innovation
Authors: Cunha Jorge , Benneworth Paul , Oliveira Pedro
Published: March 2017

In the last two decades, a renewed interest on the concepts of social innovation and social entrepreneurship has emerged. In fact, a large body of theoretical developments that occurred in the fields of innovation, territorial development, social economics, and public governance (among others) have emphasised the need to adopt new approaches to new (or emerging) problems, such as: climate change; chronic diseases; increasing inequalities in income distribution; high rates of unemployment (particularly among young people); the impact of ageing population; and mass urbanisation and social exclusion phenomenon. This chapter aims at contributing to this literature by making an attempt to distinguish both concepts: social innovation and social entrepreneurship. For that purpose, the definition of each of these concepts, their main features as well as their major differences are presented. Finally, the role that HEIs might play in promoting social innovation and social entrepreneurship initiatives is also discussed.

This article provides a critical overview over the situation of female entrepreneurship in the region, which takes into consideration challenges and opportunities on the level of the individual entrepreneurs, as well as on the macro environmental level. We finally discuss constructive solutions in order to increase the number of women business founders.
The management of the patient with non-variceal upper gastrointestinal bleeding: from evidence to clinical practice
Authors: Zippi Maddalena , Frualdo Mariella , Mucci Luciano , Zanon Marta , Marzano Chiara , Cassieri Claudio , Gnerre Paola , Crispino Pietro
Published: March 2017

A multidisciplinary group of 7 experts developed this update and expansion of the recommendations on the management of acute non-variceal upper gastrointestinal bleeding (NVUGIH) from guidelines published from 2013. The Appraisal of Guidelines for Research and Evaluation (AGREE) process and independent ethics protocols were used. Sources of data included original and published systematic reviews. Recommendations emphasize early risk stratification, by using validated prognostic scales, and early endoscopy (within 24 hours). Endoscopic hemostasis remains indicated for high-risk lesions, whereas data support attempts to dislodge clots with hemostatic, pharmacologic, or combination treatment of the underlying stigmata. Clips or thermo-coagulation, alone or with epinephrine injection, are effective methods. Second-look endoscopy may be useful in selected high-risk patients, but is not routinely recommended. Intravenous high-dose PPI therapy after successful endoscopic hemostasis decreases both rebleeding and mortality in patients with high-risk stigmata. Although selected patients can be discharged promptly after endoscopy, high-risk patients should be hospitalized for at least 72 hours after endoscopic hemostasis. For patients with UGIH who require a nonsteroidal anti-inflammatory drug, a PPI is preferred to reduce the rebleeding. Patients with NVUGIH needing secondary cardiovascular prophylaxis should start receiving acetylsalicylic acid (ASA) again as soon as cardiovascular risks outweigh gastrointestinal risks (usually within 7 days).
NT-proBNP correlates with the illness scores pneumonia severity index and CURB-65 in patients with pneumonia
Authors: Martolini Dario , Pistella Eleonora , Carmenini Enrico , Santini Claudio
Published: March 2017

Pneumonia severity index (PSI) and CURB-65 (confusion, urea, respiratory rate, blood pressure, age ≥65) are used to estimate the severity and prognosis of patients with pneumonia. NT-proBNP is a marker of myocardial stress and of sepsis-induced myocardial depression and might be used to predict short and long-term survival in patients with pneumonia. Twenty-three patients [age 79±15 standard deviation (SD); M/F 8/15, CURB-65 2.2±0.9 SD, PSI 118±38 SD, procalcitonin 3.9±5 SD] with pneumonia hospitalized in our Internal Medicine Unit were retrospectively evaluated. NT-proBNP was measured in the first 72 h of hospitalization. CURB-65 and PSI were calculated and correlation with biomarkers investigated. NT-proBNP showed a moderate statistically significant correlation with both PSI and CURB-65 (NT-proBNP vs PSI, r=0.42, P<0.05, NT-proBNP vs CURB-65, r=0.46, P<0.05). These correlations were confirmed also when patients with a diagnosis of heart failure where excluded from the analysis, even if the correlation did not reach the statistical significance. NT-proBNP seems to well correlate with the illness scores PSI and CURB-65 and might be a reliable predictor of severity and survival in patients with pneumonia.
Reconnaissance U-Pb geochronology of the crystalline core of the Boothia Uplift, District of Franklin, Northwest Territories
Authors: Frisch T , Hunt P A
Published: March 2017

Granulite facies ortho- and paragneisses and felsic intrusive rocks from the crystalline core of the Boothia Uplift, which extends northward from Boothia peninsula into the Arctic Archipelago. The rocks dated come from northern Boothia Peninsula, western
Somerset Island, and eastern Prince of Wales Island, between 71°N and 74°N. Zircon ages of protoliths of orthogneissic rocks range from 2.48 to ca. 2.2 Ga. A major thermal event, involving syenitic magmatism and high-grade metamorphism, occurred in the interval 1.94-1.92 Ga; magmatism may
have preceded metamorphism by 10 or 20 Ma. A massive, porphyritic rapakivi granite in northern Somerset Island intruded 1.71 Ga ago. Metamorphic and intrusive ages in the 1.9-2.0 Ga range in the Boothia Uplift are similar to those in the Thelon Tectonic Zone on the mainland to the southwest.
Compared with the Thelon zone, however, crystallization ages of gneissic protoliths are, in general, older and the nature of the intrusive suite is significantly different in the Boothia Uplift.
Geological and geophysical signatures of a large polymetallic exploration target at Lou Lake, southern Great Bear magmatic zone, Northwest Territories
Authors: Gandhi S S , Prasad N , Charbonneau B W
Published: March 2017

Recent metallogenic studies and a multiparameter airborne geophysical survey have revealed a potentially large polymetallic exploration target in southern Great Bear magmatic zone. Its geological setting comprises an early Proterozoic metasedimentary platform
sequence, intruded by granitic plutons and overlain unconformably by a gently dipping rhyolitic volcanic assemblage, which was emplaced during the Great Bear magmatic activity ca. 1865 Ma. The metasedimentary and volcanic rocks form a northwest-trending belt, and host numerous Bi-Cu-Co-Au-As-bearing
arsenopyrite-pyrite-magnetite veins and disseminations, localized mainly at the unconformity. This hydrothermal mineralization is characterized by strong potassium enrichment over a 3 x 4 km area, coincident with high magnetic and low eTh/K ratio anomalies, detected by the airborne survey. Follow-up
exploration by industry has revealed a coincident gravity anomaly that enhances potential for a large deposit of the type related to the giant Olympic Dam deposit in South Australia.
Groundwater prospects in the Oak Ridges Moraine area, southern Ontario: application of regional geological models

Published: March 2017

A geological model is presented for the glacial deposits of the Oak Ridges Moraine area of southern Ontario. The model contains four units as well as incised channels dissecting the strata. Channels eroded through the Newmarket Till, a regional aquitard, provide
hydraulic connection between the aquifers of the overlying Oak Ridges Moraine and those of the underlying lower drift. Buried channels filled with silt, sand, and gravel, and preferentially oriented north-northeast-south-southwest, are indicated by drill core and seismic reflection profiles. The
model, with two successful case studies, has significant implications for groundwater resource development in the Greater Toronto Area. Groundwater flow to the lower drift may occur through channels so that groundwater resources in the lower drift may be more productive than previously suggested.
Gravel sequences within channels may be targets for high yield wells. Further investigations are required to examine buried channel locations, distribution, and sediment fill.

Authors: Whalen J B , Struik L C , Hrudey M G
Published: March 2017

The Endako map area (93K/3) is underlain by two main bedrock assemblages translated and tilted by Tertiary strike-slip and extension faulting. A Mesozoic complex, consisting of various Cretaceous and Jurassic granitic to dioritic phases, has been subdivided, from
oldest to youngest, into the Boer, Stag Lake, and Francois Lake suites. The youngest suite, which hosts the Endako molybdenum mine, consists of granodioritic to granitic units that grade into aplitic phases containing miarolitic cavities. A Tertiary complex consists of Eocene Ootsa Lake Group
dacite, rhyolite, andesite, and basalt, and Eocene and Oligocene Endako Group basalt. The Ootsa Lake Group is dominated by intermediate crystal tuffs and includes interlayered mafic and felsic volcanic rocks.
Overview of science program, JAPEX/JNOC/GSC Mallik 2L-38 gas hydrate research well
Authors: Dallimore S R , Collett T S , Uchida T
Published: March 2017

The JAPEX/JNOC/GSC Mallik 2L-38 gas hydrate research well was drilled in February and March, 1998, in the Mackenzie Delta, Northwest Territories, Canada, to a depth of 1150 m. The scientific program was conducted through a collaborative agreement between the
Japan National Oil Corporation and the Geological Survey of Canada with key participation by the Japan Petroleum Exploration Company and the United States Geological Survey. A primary objective of the well was to undertake a comprehensive scientific research program to study an arctic gas hydrate
accumulation. Field research conducted as part of the Mallik 2L-38 program included collection of permafrost and gas-hydrate-bearing core samples, downhole geophysical logging, and a vertical seismic profile survey. Laboratory and modelling studies undertaken during the field program, and
subsequently as part of a post-field research program, documented the sedimentology, biostratigraphy, physical/petrophysical properties, pore-water and gas geochemistry, geophysics, and reservoir characteristics of the Mallik field gas hydrate accumulation.
Cryo-electron microscopic studies of structures and composition of Mallik gas-hydrate-bearing samples
Authors: Techmer K S , Heinrichs T , Kuhs W F
Published: March 2017

Microstructures of gas hydrate samples from the Mallik 2002 Gas Hydrate Production Research Well Program were studied using a field-emission scanning electron microscope equipped with a nitrogen-cooled cold stage. All samples investigated came from varying depths
of the main production research well, JAPEX/JNOC/GSC et al. Mallik 5L-38. They consist of sedimentary silicate particles embedded in gas hydrate. Besides a dense type of methane hydrate, numerous submicrometre- to micrometre-sized, porous regions of gas hydrate were found. Single tube pores with
diameters of a few micrometres and lengths of up to several hundreds of micrometres were abundant.

Similar porous microstructures were also found in laboratory experiments as well as in seafloor gas hydrate from Hydrate Ridge offshore Oregon. From the authors' experiments it appears that such porous gas hydrate deposits are formed when free gas is available.

A reduction theorem for Dade’s projective conjecture
Authors: Späth Britta
Published: March 2017

In this paper, we propose a strengthening of Dade’s Conjecture. This version, called the Character Triple conjecture, once assumed for quasisimple groups, is shown to imply Dade’s Projective Conjecture for all finite groups. In particular Dade’s Projective Conjecture holds for a group whose nonabelian simple sections have only covering groups satisfying the Character Triple Conjecture. We verify the new conjecture for some classes of quasisimple groups.
Mirror symmetry for exceptional unimodular singularities
Authors: Li Changzheng , Li Si , Saito Kyoji , Shen Yefeng
Published: March 2017

In this paper, we prove the mirror symmetry conjecture between the Saito–Givental theory of exceptional unimodular singularities on the Landau–Ginzburg B-side and the Fan–Jarvis–Ruan–Witten theory of their mirror partners on the Landau–Ginzburg A-side. On the B-side, we develop a perturbative method to compute the genus-0 correlation functions associated to the primitive forms. This is applied to the exceptional unimodular singularities, and we show that the numerical invariants match the orbifold-Grothendieck–Riemann–Roch and WDVV calculations in FJRW theory on the A-side. The coincidence of the full data at all genera is established by reconstruction techniques. Our result establishes the first examples of LG-LG mirror symmetry for weighted homogeneous polynomials of central charge greater than one (i.e. which contain negative degree deformation parameters).
Étale twists in noncommutative algebraic geometry and the twisted Brauer space
Authors: Antieau Benjamin
Published: March 2017

This paper studies étale twists of derived categories of schemes and associative algebras. A general method, based on a new construction called the twisted Brauer space, is given for classifying étale twists, and a complete classification is carried out for genus 0 curves, quadrics, and noncommutative projective spaces. A partial classification is given for curves of higher genus. The techniques build upon my recent work with David Gepner on the Brauer groups of commutative ring spectra.

The aim of this paper is to design a diffractive optical element based on the laser junction numerical model. We assumed a ?long? laser junction emitting quasi-monochromatic, spatially incoherent light that corresponds to the high power laser. Diffractive optics approach can be used due to the narrowband illumination. The especially designed numerical junction model was experimentally verified. Then a numerically designed diffractive focusing element was manufactured and tested in the experimental setup.

Semiconductor photorefractive quantum wells belong to materials with strong optical nonlinearity. One of the parameters that may affect the course of nonlinear phenomena in these materials is the electron and hole trapping coefficient. We present the results of a numerical analysis aimed to find out, how electric field-dependent trapping coefficients affect the process of space-charge field formation in multiple quantum wells in the phenomenon of photorefractive two-wave mixing.

Meaningful Use of an Electronic Personal Health Record (ePHR) among Pediatric Cancer Survivors
Authors: Williamson Rebecca S , Cherven Brooke O , Marchak Jordan Gilleland , Edwards Paula , Palgon Michael , Escoffery Cam , Meacham Lillian R , Mertens Ann C
Published: March 2017

Background and Objectivs: Survivors of pediatric and adolescent cancer are at an increased risk of chronic and debilitating health conditions and require life-long specialized care. Stand-alone electronic personal health records (ePHRs) may aid their self-management. This analysis characterizes young adult survivors and parents who meaningfully use an ePHR, Cancer SurvivorLinkTM, designed for survivors of pediatric and adolescent cancer.

Methods: This was a retrospective observational study of patients seen at a pediatric survivor clinic for annual survivor care. Young adult survivors and/or parent proxies for survivors <18 years old who completed ePHR registration prior to their appointment or within 90 days were classified as registrants. Registrants who uploaded or downloaded a document and/or shared their record were classified as meaningful users.

Results: Overall, 23.7% (148/624) of survivors/parents registered and 38% of registrants used SurvivorLink meaningfully. Young adult registrants who transferred to adult care during the study period were more likely to be meaningful users (aOR: 2.6 (95% CI: 1.1, 6.1)) and used the ePHR twice as frequently as those who continued to receive care in our institution’s pediatric survivor clinic. Among survivors who continued to receive care at our institution, being a registrant was associated with having an annual follow-up visit (aOR: 2.6 (95% CI: 1.2, 5.8)).

Conclusions: While ePHRs may not be utilized by all survivors, SurvivorLink is a resource for a subset and may serve as an important bridge for patients who transfer their care. Using SurvivorLink was also associated with receiving recommended annual survivor care.

Abstract. Recent research in large-scale hydroclimatic variability is surveyed, focusing on five topics: (i) variability in general, (ii) droughts, (iii) floods, (iv) land-atmosphere interactions, and (v) hydroclimatic prediction. Each surveyed topic is supplemented by illustrative examples of recent research, as presented at a 2016 symposium honoring the career of Professor Eric Wood. Taken together, the recent literature and the illustrative examples clearly show that research into hydroclimatic variability continues to be strong, vibrant, and multifaceted.
General design equations for the rotational stiffness, maximal angular deflection and rotational precision of various notch flexure hinges
Authors: Linß Sebastian , Schorr Philipp , Zentner Lena
Published: March 2017

Abstract. Notch flexure hinges are often used as revolute joints in high-precise compliant mechanisms, but their contour-dependent deformation and motion behaviour is currently difficult to predict. This paper presents general design equations for the calculation of the rotational stiffness, maximal angular elastic deflection and rotational precision of various notch flexure hinges in dependence of the geometric hinge parameters. The novel equations are obtained on the basis of a non-linear analytical model for a moment and a transverse force loaded beam with a variable contour height. Four flexure hinge contours are investigated, the semi-circular, the corner-filleted, the elliptical, and the recently introduced bi-quadratic polynomial contour. Depending on the contour, the error of the calculated results is in the range of less than 2 % to less than 16 % for the suggested parameter range compared with the analytical solution. Finite elements method (FEM) and experimental results correlate well with the predictions based on the comparatively simple and concise design equations.
General, regional or local anesthesia for successful radial cephalic arteriovenous fistula
Authors: Shemesh David , Raikhinstein Yefim , Goldin Ilya , Olsha Oded
Published: March 2017

Autogenous fistulas and in particular radiocephalic fistulas are recommended as the first vascular access for hemodialysis. Unfortunately, the rates of early failure and non-maturation are very high. For more than a decade, brachial plexus block has been proposed as the anesthesia of choice for fistula creation due to its beneficial sympathectomy-like effect, causing vasodilation and attenuation of spasm. Until recently, there was not a single randomized clinical study supporting this proposition. Because performing regional anesthesia is time-consuming and requires expertise, many surgeons prefer local or general anesthesia for vascular access surgery. However, in August 2016 a randomized clinical trial was published showing that regional anesthesia significantly reduces early failure and improves primary and functional patency at 3 months compared to local anesthesia. The aging of the dialysis population, with their attendant morbidity and increased risk for general anesthesia, makes it clear that regional anesthesia is the recommended approach for fistula creation. The excess time required for this approach will decrease with increasing expertise along the learning curve, and will be compensated by a reduction in time that would otherwise be needed for new access construction due to failure of fistulas constructed under local anesthesia.

Este artigo pretende, primeiro, fundamentar a existência de uma crisemundial como fenômeno único, caracterizado como crise civilizacional, pormeio do diálogo de diversos autores de diferentes áreas do conhecimentocujas constatações e reflexões conduzem ao mesmo sentido: há de fato umasituação emergente cujos sintomas se manifestam nos mais diversos segmentosda atuação humana no planeta. A partir daí, busca-se, então, a existência deuma relação de causalidade entre a crise já constatada e a sociedade moderna(científica, racionalista, industrial). Em seguida, e o tanto que cabe nas dimensõesdeste artigo, busca-se responder a boa pergunta: a partir de quando e como sedeu a construção dessa mentalidade que por sua vez engendrou um paradigma,uma visão de mundo, uma base de pressupostos científicos tacitamente aceitose que subjazem na cultura e no estilo de vida ocidental dominante que por tudose mostra insustentável. Em seguida, por meio de quatro autores, arautos denovas abordagens científicas, busca-se mostrar como a própria ciência está adesvelar um novo paradigma que amplia essa visão dominante e abre novoshorizontes para nossa compreensão da natureza e do homem numa perspectivade práticas sustentáveis na qual a cultura e a natureza não estejam emposições contraditórias. Complexidade, pensamento sistêmico, visão holística etransdisciplinaridade são as portas que se abrem e nos conduzem a essa novapossibilidade do homem ante o impasse que ele mesmo criou.

Os veículos são a principal fonte dos poluentes atmosféricos nos centrosurbanos. As tecnologias mais importantes para a redução dos poluentes emveículos automotores foram o controle eletrônico da injeção de combustíveise a utilização de catalisador no sistema de exaustão dos veículos. O objetivodeste trabalho foi avaliar se a renovação da frota de veículos alterou aqualidade do ar em Curitiba. Foi realizado o levantamento do histórico dasconcentrações dos poluentes do ar, no período de 2003 a 2014, e do históricoda frota de veículos de Curitiba – com base em dados do Departamentode Trânsito do Paraná (DETRAN-PR). Verificou-se um aumento de 65% nonúmero de veículos, que não resultou no aumento da concentração dospoluentes. As concentrações de poluentes apresentaram queda ao longo doperíodo avaliado. Conclui-se que a renovação da frota proporcionou umamelhoria na qualidade do ar em Curitiba.

Predicting Intentions to Purchase Sustainable Apparel in China: A Structural Equation Modeling Approach
Authors: Han Yan
Published: March 2017

The present study aims at exploring psychological determinants of intention to purchase sustainable apparel within the framework of the Theory of Planned Behavior (TPB). A convenience sample of 784 university students studying in three major cities (Beijing, Shanghai, and Dalian) of China completed the anonymous surveys. All antecedents included in this study were significantly related to intention of sustainable apparel purchasing. Among them, the most important predictor of Intention to purchase sustainable apparel was individuals’ Attitude towards buying sustainable apparel, followed by Perceived Behaviour Control and Subjective Norm. The TPB was proved to be a reliable predictive model of intention to purchase sustainable apparel in the Chinese context. Findings from this study give readers an understanding of the magnitude and significance of relationships between antecedents and intention in the sustainable apparel consumption domain. These results lead to suggestions for policy makers, marketers and stakeholders involved in the sustainable apparel market.

Violence against police officers: perception and justifications of suspects

This paper tries to answer the question why defendants use violence against police officers and whether, and if so how, they construct justifications for their own behavior. The study consists of an analysis of the situational aspects of violence against police officers and the characteristics of suspects. In addition, some suspects were interviewed about the incident in which they were involved. They were asked what their perception of the situation was, and what the background of the violence was. They were also asked for their opinion on the image of the police in general, and for their knowledge and perception of the relevant laws and regulations. The conclusion is that the motives for violence against a police officer lie in their belief that all men, police officer or not, are equal and should be treated with respect. Suspects feel treated unfairly and disrespectfully by police officers. Suspects feel that in such cases they are entitled to use force. Suspects are not aware of the differences between their own rights and responsibilities in such a situation and the authority that police officers legally have to use of force in order to perform their legal tasks.

End-user perceptions of safety and security of online banking

In today’s society, full use is made of online banking. This makes safety and security of online banking an important issue. Two significant threats to users of online banking in The Netherlands are phishing and malware attacks. In this study, an end-user perspective is adopted to study customers’ perceptions regarding safety and security of online banking. A unique feature to this study is that we explore – besides other predictor variables – the relationship between online banking fraud victimization and risk perception. We have made a distinction between three types of victimization: 1) self-experienced victimization, 2) victimization of acquaintances, such as family and friends, and 3) having heard of stories in the media about online banking fraud victimization. Based on a secondary analysis of data from 1200 Dutch users of online banking, collected through an online survey, we conclude that participants perceive their risk of online banking fraud to be small. In general, participants have little experience with victimization, both themselves (2.3%) and in social settings (29.6%). Three quarters of the respondents (75.6%) are aware of victimization of online banking fraud by means of media coverage. Direct and indirect victimization, however, have almost no influence on risk perception regarding online banking fraud. Risk perception is mainly determined by perceived vulnerability, that is, the estimated probability of becoming a victim of online banking fraud. Furthermore, perceived severity or impact of online banking fraud and the degree of trust in online banking contribute to some extent to risk perception. In total, 64.0% of variance in risk perception was explained by the predictors perceived vulnerability, perceived severity, locus of control, trust in online banking, (in)direct experiences with victimization (self, acquaintances and media) and demographic variables (gender, age, educational level and work status). The results of this study may help to improve communication about risks regarding online banking.
[Eosinophilic pancreatitis and autoimmune pancreatitis: comparison, differential diagnosis, and treatment]
Authors: Turrin Mauro , Martinelli Sergio
Published: March 2017

Among the rarest causes of acute pancreatitis, there are eosinophilic pancreatitis (EP) and autoimmune pancreatitis (AIP). They share some features, such as the low frequency and the association with systemic disorders. Their diagnostic criteria, mainly clinical and laboratory, are different, but both require histological confirmation in most cases: in fact, pancreas is enlarged at CT scan, with tumor-like appearance.Here we discuss the importance of hypereosinophilia in EP and IgG increase in type 1 AIP (included in IgG-related systemic diseases). Differential diagnosis with pancreatic neoplasms and therapy schedules are discussed as well.
Breeding behavior of female white‐tailed deer relative to conception: Evidence for female mate choice
Authors: Sullivan Jeffery D. , Ditchkoff Stephen S. , Collier Bret A. , Ruth Charles R. , Raglin Joshua B.
Published: March 2017

Female white‐tailed deer (Odocoileus virginianus) are thought to choose between two behavioral strategies to maximize the quality of potential mates: sit and wait, characterized by concentrating activity within a restricted area, and excursive behavior, characterized by increased activity and excursions outside the home range. As movement patterns may influence conception, our goal was to examine the patterns of female white‐tailed deer movements to evaluate which breeding strategy was employed. We equipped 36 female white‐tailed deer with GPS collars from August 2013 to December 2015. We found that movement rate and probability of activity were greatest near the peak of the breeding season, and we observed increases in both metrics during the 40 days prior to estimated conception. Peak size of home range and core area occurred in the days surrounding conception. We found that 11 deer performed an excursion, ranging from 43 days before until 36 days after conception, with the peak probability of being outside of an individual home range occurring 1 day prior to conception. Our results suggest that female white‐tailed deer may attempt to maximize the quality of their mates by advertising availability for breeding through excursive behaviors just prior to entering estrus.
The Gravity of High-Skilled Migration Policies
Authors: Czaika Mathias , Parsons Christopher R.
Published: March 2017

Combining unique, annual, bilateral data on labor flows of highly skilled immigrants for 10 OECD destinations between 2000 and 2012, with new databases comprising both unilateral and bilateral policy instruments, we present the first judicious cross-country assessment of policies aimed to attract and select high-skilled workers. Points-based systems are much more effective in attracting and selecting high-skilled migrants than requiring a job offer, labor market tests, and shortage lists. Offers of permanent residency, while attracting the highly skilled, overall reduce the human capital content of labor flows because they prove more attractive to non-high-skilled workers. Bilateral recognition of diploma and social security agreements foster greater flows of high-skilled workers and improve the skill selectivity of immigrant flows. Conversely, double taxation agreements deter high-skilled migrants, although they do not alter overall skill selectivity. Our results are robust to a variety of empirical specifications that account for destination-specific amenities, multilateral resistance to migration, and the endogeneity of immigration policies.
JEŚMANOWICZ’ CONJECTURE ON PYTHAGOREAN TRIPLES

Published: March 2017

In 1956, Jeśmanowicz conjectured that, for any positive integers $m$ and $n$ with $m>n$, $\gcd (m,n)=1$ and $2\nmid m+n$, the Diophantine equation $(m^{2}-n^{2})^{x}+(2mn)^{y}=(m^{2}+n^{2})^{z}$ has only the positive integer solution $(x,y,z)=(2,2,2)$. In this paper, we prove the conjecture if $4\nmid mn$ and $y\geq 2$.
