Surface Drift Currents Induced by Waves and Wind in a Large Tank

The empirical features of surface drift currents induced by both mechanical and wind waves are presented. The measurements were made by using surface floats in a large tank with dimensions of 32.5 × 1 × 2 m3. Three cases were studied: (i) regular (narrowband) mechanical waves, (ii) irregular (wideband) mechanical waves, and (iii) wind waves. The measured surface drift currents induced by mechanical waves Ud are compared with the Stokes drift at the surface USt estimated by a well-known formula with an integral over the wave spectrum. In this case, the ratio Ud/USt varies in the range of 0.5–0.93 and slightly increases with decreasing wave steepness. No visible dependence on the breaking intensity is observed. In the case of wind waves, the wind-induced part of the surface drift Udw is compared with the friction velocity u*. In our measurements, the ratio Udw/u* varies systematically in the range of 0.65–1.2. Considering the percentage of wave breaking Br, the wave age A, and the wave steepness Ϭ, the parameterization of Udw was obtained in the form Udw = (Br + ϬA)u*, which corresponds to the observations with a mean error of 10%. For the first time, this ratio provides the dependence of wind-induced drift on the surface wave parameters. The obtained results and problems related to measuring surface drift currents are discussed.
Delving into the Role of Celebrity Chefs and Gourmets in Culinary Destination Marketing

This paper aims to explore the role of celebrity chefs and gourmets in culinary destination marketing based on the perceptions of celebrity chefs and gourmets. Drawing on qualitative data collected through 20 semi-structured interviews with celebrity chefs and gourmets in Turkey, the findings highlight the role of these celebrities in culinary destination marketing. This role is shaped through three key interconnected dimensions; namely, provocativeness, credibility, and supportiveness. The study is among the first attempts to explore, in an integrated manner, the role of celebrity chefs and gourmets from a destination marketing perspective. The study makes several theoretical contributions and proposes practical implications for practitioners in both destinations and firm levels.
Movilización pasiva continua en pacientes con artroplastia de rodilla

Introduccion: La artroplastia total de rodilla es el recurso terapeutico para pacientes con artrosis severa y gran incapacidad fisica. Sin embargo, muchos evolucionan con dolor y deficit funcional. En este estudio, se utiliza un tratamiento con movilizacion pasiva continua a partir de los 10 dias de la cirugia. Materiales y Metodos: Se incluyo a 60 pacientes que fueron asignados, en forma aleatoria, a 2 grupos (30 en cada grupo). Al grupo 1 (G1, 23 mujeres) se le aplico un protocolo de tratamiento convencional y, al grupo 2 (G2, 17 mujeres), el mismo programa y la adiccion de un equipo de movimiento pasivo continuo a los 10 dias de la intervencion. Se evaluaron el dolor, la movilidad articular, la fuerza muscular y la funcion (WOMAC y prueba TUG). Resultados: No se observaron diferencias estadisticamente significativas en los parametros estudiados, aunque si una tendencia a la mejoria en el G2. En este grupo, la fuerza de extension de la rodilla fue mayor y tambien hubo una correlacion basal entre la fuerza y la prueba TUG. Conclusiones: El uso diferido de la movilizacion pasiva continua mejoro la fuerza de extension de la rodilla y el rendimiento en la prueba TUG, aunque sin diferencias significativas entre ambos grupos. No se observaron efectos adversos. Nivel de Evidencia: I
Sustainability implementation challenges in food supply chains: a case of UK artisan cheese producers

Abstract Food supply chains are receiving increased attention due to rapid depletion of natural resources, increasing quality standards and rising food safety and security concerns. Implementing sustainability practices in food supply chains is believed to overcome such emerging challenges. However, limited studies address sustainability implementation concerns, particularly in cold food supply chains. Thus, this study attempts to identify factors hindering sustainability implementation in cold food chain networks by considering a case of UK artisan cheese producers. Survey data is utilised to identify and prioritise barriers for implementing sustainability following fuzzy analytic hierarchy process and sensitivity analysis. The analysis identified several key barriers, including initial investment cost, firm size and unawareness of government regulations. The internal barriers significantly dominate the implementation of sustainability practices in comparison to external barriers. Lack of consensus regarding the concept of sustainability by different stakeholders is observed to be an issue negatively affecting the level of integration in SMEs. Findings will help food and dairy SME's in gaining competitive advantage through the successful implementation of sustainability practices.
The exhaustion of the herding effect in peer-to-peer accommodation

A significant reason for the concentration of demand in a subset of the supply in the peer-to-peer market for tourist accommodation is herding behavior, by which the decisions of the first guests are imitated by those who follow. This article proposes a profit- and utility-maximization microeconomic model and implements it with data of Airbnb listings corresponding to 10 European cities. Results show that the influence of each additional review is positive but decreasing, inducing a more balanced distribution of demand among offered accommodation and thus dampening the herding effect. Moreover, reservation policy—specifically, enabling the instant booking option—is a key to explain the initial push that accommodations need to be demanded now and, hence, to increase their possibilities of being demanded in the future.
Do Spatially Explicit Wildlife Exposure Models Improve the Estimation of Risk for Small Mammals? Case Study: Application of SEEM to Small Mammal Exposures to Lead in Heterogeneous Landscapes.

Understanding risks to terrestrial wildlife species from exposure to chemicals in the environment requires knowledge of how species make habitat decisions and how subsequent exposure events occur. Heterogeneity of chemical distribution and of habitat quality can influence exposure. Previous studies in birds have shown that individually-based, spatially-explicit models can be useful in predicting exposure and risk; however, studies investigating these influences in small mammals with limited ranges have been lacking. Here we test a spatially explicit, individually-based exposure model (Spatially Explicit Exposure Model; SEEM) where model predictions based on life history traits, habitat preferences, and varying soil lead concentrations are used and compared those with field-collected blood or tissue lead (Pb) concentrations in small (e.g., Peromyscus, Blarina spp.) and medium-sized mammalian species (e.g., Lepus spp) at three Pb-contaminated sites. These species were chosen as they were expected to be present in suitable habitat and Pb was modelled when adequate tissue-based toxicity thresholds were available. Oral exposure estimates from SEEM were compared with a traditional deterministic model and with field-collected tissue Pb concentrations using ecological hazard quotients (EHQs) to normalize between oral and real-time tissue Pb concentrations. EHQs at the 90% population effect level (for SEEM) and at the 95% upper confidence level (assuming a single lead concentration with no consideration of habitat quality in the deterministic model) were compared with maximum EHQs developed from blood/tissue Pb concentrations. SEEM and deterministic estimates were similar for small mammal species, yet slightly over-predicted risk compared to field tissue/blood Pb data. Estimates for hares (medium sized mammal) using SEEM provided more accurate predictions compared with field tissue data. These data suggests that spatially explicit models may be sensitive to grain size, as small mammals experience the environment in limited spatial contexts; a scale at which habitat may not change significantly.

Investigating the effects of handedness on the consistency of lateralization for speech production and semantic processing tasks using functional transcranial Doppler sonography

ABSTRACT The left hemisphere is dominant for language in most people, but lateralization strength varies between different tasks and individuals. A large body of literature has shown that handedness is associated with lateralization: left handers have weaker language lateralization on average, and a greater incidence of atypical (right hemisphere) lateralization; but typically, these studies have relied on a single measure of language lateralization. Here we consider the relationships between lateralization for two different language tasks. We investigated the influence of handedness on lateralization using functional transcranial Doppler sonography (fTCD), using an existing dataset (N = 151 adults, 21 left handed). We compared a speech production task (word generation) and a semantic association task. We demonstrated stronger left-lateralization for word generation than semantic association; and a moderate correlation between laterality indices for the two tasks (r = 0.59). Laterality indices were stronger for right than left handers, and left handers were more likely than right handers to have atypical (right hemisphere) lateralization or inconsistent lateralization between the two tasks. These results add to our knowledge of individual differences in lateralization and support the view that language lateralization is multifactorial rather than unitary.
Prevalence and Effect of Obesity on Mobility According to Different Criteria in Polio Survivors

Supplemental digital content is available in the text. Objective Obesity is a major and functionally important problem in polio survivors. The aim of this study was to investigate the prevalence of obesity using body mass index and percentage body fat in polio survivors and to analyze the relationship between obesity and mobility. Design Eighty-four polio survivors were included. Anthropometric parameters, knee extensor strength, and the Short Physical Performance Battery were evaluated. A questionnaire was used to explore the late effects of poliomyelitis. Obesity was determined using both body mass index and percentage body fat. Results The prevalence of obesity in polio survivors was 39.3% and 81.5% using the body mass index and percentage body fat criteria, respectively. The Short Physical Performance Battery scores were significantly different between the obese and nonobese groups as determined by percentage body fat (P < 0.05). Only percentage body fat was significantly associated with mobility after controlling for the confounding variables in obese polio survivors (P < 0.05). Conclusions Obesity in polio survivors was underestimated when the body mass index criteria were used. Percentage body fat was a significantly associated factor for mobility in obese polio survivors. Obesity determined by percentage body fat criteria is useful to address obesity-related problems in polio survivors.
Public Library as a Source of Business Information for Small-Scale Business Enterprises in Nigeria

ABSTRACT The study investigated public library as a source of business information for small-scale business enterprises in Nigeria. Six states in the Southwest region of Nigeria were used for the study, while purposive sampling was used to select forty small-scale businesses from each of the states, which brought the population of the study to 240. As a survey research, a questionnaire was used for data collection. The findings of the study revealed that information on sources of business funding was the major information need of small-scale businesses, while books were the most available information sources in the public library. Based on the findings, the study recommends among others, that government should provide more funding to support small-scale businesses; and that public libraries should acquire more information sources particularly those on sources of business funding, to complement available ones. The study contributes to literature and its empirical data will be useful to policymakers on how to reposition public libraries for effective provision of business information to small-scale business people.
The Stromal Cell-derived Factor-1/CXCL12 3’A-gene Polymorphism is Related to the Increased Risk of Coronary Artery Disease: A Systematic Review and Meta-analysis

BACKGROUND: Single-nucleotide polymorphism in the stromal cell-derived factor-1 (SDF-1)/CXCL12 gene had been associated with an increased risk of coronary artery disease (CAD). However, several published studies have shown inconsistent results. AIM: A meta-analysis was assessed to evaluate the association between SDF-1 3’A-gene polymorphism and CAD in the literature. METHODS: A systematic review was conducted in accordance with PRISMA guidelines and adhering to the Cochrane Handbook for Systematic Reviews. The literature search strategy was carried out on April 3, 2019, from PubMed, EBSCO, Google Scholar, and DOAJ during 2013–2018 period using various keywords related to SDF-1, CXCL12, polymorphism, and CAD. Original data from the group, case-control study, English full-text, and DNA polymorphism assessment using polymerase chain reaction were enrolled. Gene polymorphism in A-base nucleotide among patients with CAD and healthy subjects were evaluated. All data were analyzed using Review Manager 5.3 (Cochrane, Denmark) for meta-analysis. RESULTS: Five eligible studies extracted for data analysis (2013–2018) based on the assessment of 2-independent reviewers. Several studies have been excluded due to irrelevant criteria evaluated. A significant result was found between SDF-1 3’A gene polymorphism with the increased risk of CAD in the overall effect evaluation using a fixed-effects model (odds ratio [OR]: 2.02; 95% confidence interval 1.54-2.65; I2: 34%; p<0.001) on the forest plot. CONCLUSION: Our meta-analysis suggests that gene polymorphism in A-base nucleotide of SDF-1/CXCL-12 was associated with the susceptibility of CAD. However, a bigger-scale and well-design of case-control study should be conducted to clarify these conclusions.
A NOVEL AND EFFICIENT TECHNIQUE FOR PREVENTION OF XSS ATTACKS USING KNAPSACK BASED CRYPTOGRAPHY

A BSTRACT . The problem is to protect cookies from cross-site scripting attacks (XSS). The major challenges with the cookies are user information, no randomness, no secure transportation and size etc. There is always very easy chance for attackers to attack. There are many XSS detection and prevention techniques available but have their own limitations. In this paper we propose a client side solution to protect the cookies from the XSS attacks. We propose a knapsack cryptographic local proxy with encryption and decryption capability. This approach encrypts the cookies value (session-ID) attribute in the cookie at cryptographic local proxy before sending it to the browser, Further the requests of client with encrypted cookie is sent to cryptographic local proxy where it de-crypts these requests and forward them to the web server. This technique will let Browser store the encrypted cookie which will not be useful for the attacker even if it is stolen.
Go the distance: left-right orientations, partisanship and the vote

ABSTRACT Do ideological orientations have different effects on citizens without party ties, citizens who identify with a particular party and citizens who identify with other parties? What conditional effects do partisan and ideological orientations have on the vote? Difficulties and controversies over definitions of partisanship and left-right ideology, their reciprocal effects and how these are overshadowed in analyses including both heuristics have discouraged scholars from conducting extensive comparative research on this topic. I test to what extent the effects of left-right orientations on voting differ depending on party attachments and how this relationship is influenced by party polarization. Results using data from 77 harmonized national studies in 17 European countries suggest that the effects of partisanship on vote choice are not additive to those of left-right orientations, while the latter are conditional on party identification. Thus, partisans, non-partisans and partisans of other parties respond differently to left-right distances. These differences are more pronounced when the degree of polarization is considered.
NVM-Shelf: Secure Hybrid Encryption with Less Flip for Non-Volatile Memory

The Non-Volatile Memory (NVM), such as PRAM or STT-MRAM, is often adopted as the main memory in portable embedded systems. The non-volatility triggers a security issue against physical attacks, which is a vulnerability caused by memory extraction and snapshots. However, simply encrypting the NVM degrades the performance of the memory (high energy consumption, short lifetime), since typical encryption causes an avalanche effect while most NVMs suffer from the memory-write operation. In this paper, we propose NVM-shelf: Secure Hybrid Encryption with Less Flip (shelf) for Non-Volatile Memory (NVM), which is hybrid encryption to reduce the flip penalty. The main idea is that a stream cipher, such as block cipher CTR mode, is flip-tolerant when the keystream is reused. By modifying the CTR mode in AES block cipher, we let the keystream updated in a short period and reuse the keystream to achieve flip reduction while maintaining security against physical attacks. Since the CTR mode requires additional storage for the nonce, we classify write-intensive cache blocks and apply our CTR mode to the write-intensive blocks and apply the ECB mode for the rest of the blocks. To extend the cache-based NVM-shelf implementation toward SPM-based systems, we also propose an efficient compiler for SA-SPM: Security-Aware Scratch Pad Memory, which ensures the security of main memories in SPM-based embedded systems. Our compiler is the first approach to support full encryption of memory regions (i.e., stack, heap, code, and static variables) in an SPM-based system. By integrating the NVM-shelf framework to the SA-SPM compiler, we obtain the NVM-shelf implementation for both cache-based and SPM-based systems. The cache-based experiment shows that the NVM-shelf achieves encryption flip penalty less than 3%, and the SPM-based experiment shows that the NVM-shelf reduces the flip penalty by 31.8% compared to the whole encryption.
Estimation of a Within-Herd Transmission Rate for African Swine Fever in Vietnam

Simple Summary We describe results from a panel study in which pigs from a 17-sow African swine fever (ASF) positive herd in Thái Bình province, Vietnam, were followed over time to record the date of onset of ASF signs and the date of death from ASF. Our objectives were to (1) fit a susceptible-exposed-infectious-removed disease model to the data with transmission coefficients estimated using approximate Bayesian computation; (2) provide commentary on how a model of this type might be used to provide decision support for disease control authorities. Detailed datasets of epidemics afflicting smallholder herds are rare. This study provides insight into how ASF progresses in a small-scale semi-intensive pig herd in Vietnam and generated a dataset that facilitated the use of a modeling approach to describe the transmission dynamics in this frequently underreported sector. Abstract We describe results from a panel study in which pigs from a 17-sow African swine fever (ASF) positive herd in Thái Bình province, Vietnam, were followed over time to record the date of onset of ASF signs and the date of death from ASF. Our objectives were to (1) fit a susceptible-exposed-infectious-removed disease model to the data with transmission coefficients estimated using approximate Bayesian computation; (2) provide commentary on how a model of this type might be used to provide decision support for disease control authorities. For the outbreak in this herd, the median of the average latent period was 10 days (95% HPD (highest posterior density interval): 2 to 19 days), and the median of the average duration of infectiousness was 3 days (95% HPD: 2 to 4 days). The estimated median for the transmission coefficient was 3.3 (95% HPD: 0.4 to 8.9) infectious contacts per ASF-infectious pig per day. The estimated median for the basic reproductive number, R0, was 10 (95% HPD: 1.1 to 30). Our estimates of the basic reproductive number R0 were greater than estimates of R0 for ASF reported previously. The results presented in this study may be used to estimate the number of pigs expected to be showing clinical signs at a given number of days following an estimated incursion date. This will allow sample size calculations, with or without adjustment to account for less than perfect sensitivity of clinical examination, to be used to determine the appropriate number of pigs to examine to detect at least one with the disease. A second use of the results of this study would be to inform the equation-based within-herd spread components of stochastic agent-based and hybrid simulation models of ASF.
Does Talent Management Affect Employee Performance?: The Moderating Role of Work Engagement

The study aims to examine the relationship between talent management and work engagement and its impact on nurses’ performance in Indonesia. This study is also intended to understand the role of work engagement in moderating talent management and employee performance. This present study applied a quantitative method using path analysis to investigate the relationship between variables and the primary role of work engagement. The participants of the study were nurses both in privates and public hospitals in Indonesia, with a total of 376 respondents. Closed questionnaires were processed in this study with a Likert scale with five choices ranging from 1 (strongly disagree) to 5 (strongly agree). The questionnaires were entirely collected over almost five months using Google form. The results of the study confirmed that the nurse performance, both at government and private hospitals, are categorized as good, while the work engagement and talent management are also categorized as high. The findings confirmed that talent management positively influences work involvement and employee performance. In addition, this study suggests that work engagement plays an essential role in moderating between variables and provides a confirmation of the important role of talent management and work engagement for nurses’ performance.
A New 4D Four-Wing Memristive Hyperchaotic System: Dynamical Analysis, Electronic Circuit Design, Shape Synchronization and Secure Communication

In this paper, a simple four-wing chaotic attractor is first proposed by replacing the constant parameters of the Chen system with a periodic piecewise function. Then, a new 4D four-wing memristive hyperchaotic system is presented by adding a flux-controlled memristor with linear memductance into the proposed four-wing Chen system. The memristor mathematical structure model is simple and easy to implement. Dynamical analysis and numerical simulation of the memristive hyperchaotic system are carried out. Then, the electronic circuit of the hyperchaotic system is designed and implemented. The results of numerical simulation are in good agreement with the electronic circuit experiment. In addition, shape synchronization control for the 4D four-wing memristive hyperchaotic system is realized, and a communication system is designed by using the shape synchronization method. Finally, secure signal masking application is implemented on Matlab platform. In the developed secure communication scheme, the information signal overlaps with the chaotic masking signal, which improves the security of the system.
