Generalization of the Kermack-McKendrick SIR Model to a Patchy Environment for a Disease with Latency

In this paper, with the assumptions that an infectious disease has a fixed latent pe- riod in a population and the latent individuals of the population may disperse, we reformulate an SIR model for the population living in two patches (cities, towns, or countries etc.), which is a generalization of the classic Kermack-McKendrick SIR model. The model is given by a system of delay differential equations with a fixed delay accounting for the latency and non-local terms caused by the mobility of the individuals during the latent period. We analytically show that the model preserves some properties that the classic Kermack-McKendrick SIR model possesses: the disease always dies out, leaving a certain portion of the susceptible population untouched (called final sizes). Although we can not determine the two final sizes, we are able to show that the ratio of the final sizes in the two patches is totally determined by the ratio of the dispersion rates of the susceptible individuals between the two patches. We also explore numerically the patterns by which the disease dies out, and find that the new model may have very rich patterns for the disease to die out. In particular, it allows multiple outbreaks of the disease before it goes to extinction, strongly contrasting to the classic Kermack-McKendrick SIR model.
Efficient Multimedia Transmission over Scalable IoT Architecture

Today the new technology concept, called “Internet of Things” (IoT), presents a significant field of research, due to the fact that it promises many advantages to the users worldwide. Besides this, multimedia file streaming tends to be a daily user habit, as a result of the evolution of the internet and the capabilities of devices, such as mobile phones and computers. This tendency has established Cloud Computing (CC) as a vital technology due to the fact that it reduces economic costs, improves accessibility and flexibility, while it increases the total network performance too. This paper demonstrates a new technological approach for IoT architecture, where a layered implementation with the use of many cloud servers can offer optimized streaming and download, because of the significant reduction of the transfer time costs and the storage space of the Main Cloud Server (MCS). Moreover, users will have the ability to choose or adapt to their devices’ restrictions, between low up to Ultra-High Definition (UHD) quality for multimedia access and downloading, thanks to a new quality scalability feature which is introduced and is based on the new High-Efficiency Video Coding (HEVC) compression standard. Experimental results show the efficiency of the proposed approach with math formulas and graphs.
Computation of Risk Measures using Importance Sampling

Estimation of Value-at-Risk and expected shortfall using standard Monte Carlo can result in high computational cost. We make a review of importance sampling, a common method to make estimations more efficient. A “direct” approach to compute risk measures from simulations drawn from an importance sampling density is described in detail. We explain how to select an efficient importance sampling distribution for loss probability estimations in the case of normally distributed risk factor changes. Some algorithms for efficient risk measure computations are presented explicitly. By considering numerical examples, we analyze the effect of regularly updating the importance sampling density during the simulation process.

Seroprevalence of foot and mouth disease (FMD) and associated economic impact on Central Ethiopian cattle feedlots

The study was conducted in central part of Ethiopia in 2011 with the objectives to determine seroprevalence and associated economic impact on cattle feedlots. From the total of 38,187 bulls examined for foot and mouth disease (FMD) antibody, 5,536 (14.5%) was found positive and subsequently rejected from international market. The seropositivity of FMD varied from site to site and the variations were statistically significant (χ 2 = 3.28, df = 9, p < 0.001). Similarly, there was statistically significant (χ 2 = 4.55, df = 9, p < 0.001) difference between months of the year. The total annual (2011) economic loss due to bulls rejection from international market was estimated to be 3,322,269 USD which is equivalent to 56,345,682.24 ETB (1 USD = 16.96 ETB). This study indicates that FMD resulted in bulls’ rejection from international market which affect livelihood of actors in the value chain and have a major threat to national economies as they tend to affect the international trade. Therefore, directing surveillance and controlling activities at pastoral production system where FMD risk arise and appropriate intervention measures along the market chain are critical factors necessary to prevent the
Intolerance in Faith: An Investigation of the Character of Wahhabism and its Potential Role in the Radicalization of Muslim Youth

Islamic ideologies have been, in the recent decades, spread widely across the world, mainly by Muslim immigrants to the West. This has been achieved through means of scholars and preachers, books and mosques. Some individuals and groups have adopted worldviews and ideologies which have not always met eye to eye with their surrounding societies. We find in a very few, however increasing, situations that some individuals have attempted to aggravate any non-conformity that exists between their own ideology and that which surrounds them. In the most extreme cases, we have seen the use of violence and terror against innocent citizens. Research upon this phenomenon has been carried out mostly in Middle-Eastern countries or America, UK and France. Only in recent years do we find this same discussion within other countries and areas, such as Belgium, Germany and Scandinavia. This thesis has aimed to understand the concept of radicalization within the Muslim context, and thereby focused upon literature which is used and quoted by those who identify with a radical, extreme and even violent notion. The research has been carried out in three main stages. Firstly, understanding and identifying the concept of radicalization. Secondly, the existing literature was examined to determine whether any specific faith or ideology was mentioned. Lastly, the role of Wahhabism as a potentially radicalizing ideology was thoroughly explored. The main research tool for this thesis was books and articles written by established contemporary Wahhabi personalities which explain and expand the Wahhabi creed. The first step of this thesis recognized various shortcomings and problematic issues with the method of defining and applying the term 'radical'. Existing literature by prominent scholars and researchers did outline certain notions of faith which can be determined as radicalizing. These notions are specifically upheld and propagated by Wahhabi and Salafi groups, whom in certain cases also use them to justify the use of extremism and violence. Furthermore, the writings of contemporary Wahhabi scholars, widely available in European languages, seemed to allow, at the very least level, intolerance towards others and in some cases radical and extreme behavior and rhetoric.
Resveratrol, phenolic antioxidants, and saccharides in South American red wines

Wine is an important beverage with a long tradition, and its moderate consumption may be considered beneficial for human health. Although there are many studies regarding phenolic compounds in wines, there is a lack of information about antioxidants and phenolic content in South American wines. In this study, 35 South American red wines from four different countries, vintages 2004–2013, purchased at retail stores in La Paz, Bolivia, were studied. Resveratrol content, total antioxidant capacity (TAC) by the 2,2′-azino-bis(3-ethylbenzotiazoline-6-sulfonic acid) (ABTS) and ferric-reducing antioxidant power (FRAP) methods, total phenolic content (TPH), total flavonoids (TF), and main saccharides were assessed using the well-established spectrophotometric and high-performance liquid chromatography methods. The results ranged from 4 to 24 mmol/L for TAC determined by ABTS method and 14 to 43 mmol/L for TAC determined by FRAP method, 1600 to 3500 mg gallic acid equivalents/L for TPH, and 2 to 6 mmol catechin equivalents /L for TF. The resveratrol content ranged from 0.1 to 8 mg/L. Saccharides, glucose, and fructose content ranged from 0.4 to 10 g/L, 1.4 to 8.6 g/L, and 0.2 to 12 g/L, respectively. There was a high correlation among the different methods. The results showed that some wines growing at high altitude (>1500 meters above the sea level) have higher amounts of TAC and phenolic content, including resveratrol, while non-varietal wines showed the lowest values. It was also observed that the saccharose content in some wines was surprisingly high, suggesting saccharose dosing after fermentation.

Commissioning and performance of the Advanced Light Source

The Advanced Light Source (ALS) at the Lawrence Berkeley Laboratory is the first of the lower energy (1 to 2 GeV) third-generation synchrotron radiation facilities to come into operation. Designed with very small electron beam emittances, to operate with long insertion devices to produce very high brightness beams of synchrotron radiation in the VUV and soft X-ray regions of the spectrum, these facilities are complementary to the higher energy (6 to 9 GeV) facilities designed for harder X-radiation. From the earliest periods of their design it was recognized that the performance of the required low-emittance lattices would be dominated by nonlinear particle dynamics caused by the strong lattice sextupoles required for chromatic correction, the effects of undulators and wigglers, and the requirement for very narrow-gap vacuum vessels. Commissioning of the ALS storage ring began early in 1993. In this paper we will briefly review the main characteristics of the storage ring design, describe our commissioning experiences, and review the present performance and performance limitations of the facility. <<ETX>>
CULTURAL CAPITAL: ALLUSIONS, GAPS AND GLISSANDOS IN RECENT THEORETICAL DEVELOPMENTS*

The concept of cultural capital has been increasingly used in American sociology to study the impact of cultural reproduction on social reproduction. However, much confusion surrounds this concept. In this essay, we disentangle Bourdieu and Passeron's original work on cultural capital, specifying the theoretical roles cultural capital plays in their model, and the various types of high status signals they are concerned with. We expand on their work by proposing a new definition of cultural capital which focuses on cultural and social exclusion. We note a number of theoretical ambiguities and gaps in the original model, as well as specific methodological problems. In the second section, we shift our attention to the American literature on cultural capital. We discuss its assumptions and compare it with the original work. We also propose a research agenda which focuses on social and cultural selection and decouples cultural capital from the French context in which it was originally conceived to take into consideration the distinctive features of American culture. This agenda consists in 1) assessing the relevance of the concept of legitimate culture in the U.S.; 2) documenting the distinctive American repertoire of high status cultural signals; and 3) analyzing how cultural capital is turned into profits in America.

Encountering the Mukhabarat State

Chapter 2 provides guidelines for how to conduct field research in states that employ extensive intelligence apparatuses to spy on, intimidate, and harass citizens and researchers. The chapter provides advice on how to protect yourself and your data and, based on the authors’ personal experiences with the intelligence apparatus in Jordan, also on what to expect should researchers fall out of favor with intelligence services. While most scholars conduct research free of interference by the respective intelligence apparatuses of the countries of the region, this chapter gives advise on how to help ensure that this remains the case even as the region appears to be increasingly suspicious of researchers.
Is it a showstopper? Reliability assessment and criticality analysis for Wave Energy Converters

The reliability of wave energy converters (WECs) is a key issue that has to be addressed in order to make them a viable energy option. At this stage of early industrial development the reliability assessment of WECs is a challenging task. In this paper existing reliability methods, namely Reliability Block diagrams, have been applied to a notional configuration. It was found that omnipresent lack of failure rate data makes rather crude adjustments of often generic data necessary which generally lead to rather unfavourable and highly uncertain results. Reliability data is either not available due to sparse field experience or is kept confidential, within different project developments to secure competitive advantages and intellectual property. In order to foster the progress of the marine energy industry, the reliability of devices must be demonstrated and improved. This requires a joint effort between industry stakeholders to collect, share and disseminate existing failure knowledge and future operational experience.

Prevalence and Associated Factors of Attention Deficit Hyperactivity Disorder (ADHD) in a Rural Community, Central Thailand: A Mixed Methods Study

BACKGROUND: Attention Deficit Hyperactivity Disorder (ADHD) is one of the most common behavioral problems among children around the world including Thailand. The disease affects their life, parents and community when left untreated. Most information concerning ADHD in Thailand derives from hospital based studies. The present study aimed to determine the prevalence and associated factors of ADHD in a remote rural community.METHODS: A total of 495 primary school children were screened using the SNAP-IV. Positive screening cases were then diagnosed by pediatric psychiatrists according to the DSM-V criteria. Standardized questionnaires were used to collect demographic data and associated factors. A qualitative study using focus group discussions and indepth interviews was conducted to determine knowledge and perceptions regarding ADHD among teachers and main guardians.RESULTS: The prevalence of ADHD among children was 2.2%. Univariate and multivariate analysis showed that children with ADHD were associated with both familial and individual factors including being repeatedly inattentive or hyperactive in class, suspended from school, and changing school, a history of bullying and main guardians were not parents. Qualitative data showed that both main guardians and teachers had inadequate knowledge and misperceptions regarding children with ADHD. The local health care system could not detect this problem so the children with ADHD were not properly treated.CONCLUSION: Our data emphasized that ADHD was a problem in this remote rural community. Screening tests and referral systems for ADHD should be provided for rural communities.
Tailoring Software Development Methodologies for Reliability

In recent times, many organizations have sought ways of improving the quality of software products due to the complexity and continuous change in technological trends. These trends have given rise to more sophisticated software systems, which are required for proper functioning at all times. Most research literature proposes tailoring of standard development methodologies due to their inadequacies and inability to meet up with users’ needs and system requirements. Reliability engineering has become an approach towards addressing software systems complexity, and also serve as a guarantee towards quality conformance and assurance of software products. In this research paper, the importance of reliability and tailoring is discussed to lay the foundation for the integration of basic reliability engineering techniques into software development.
Examining the Effects of Decomposed Perceived Risk on Consumer's Online Shopping Behavior: A Field Study in China

Perceived risk research has drawn much attention in recent years. In investigating the roles that perceived risk plays in consumers’ online purchasing behavior, most of the studies viewed perceived risk as high-level surrogate construct, and a few focused on one or several risk facets. Few research, however, distinguished how different sources of perceived risk influence consumers’ purchase behavior. In this research, we propose to decompose online purchase perceived risk into three major source components: uncertainty of transaction cost, product performance and consumer’s individual anxiety. Empirical results from a field survey in China shows that different sources of perceived risk bring distinct effects to purchase behavior. Perceived risks from individual anxiety were found to have significant influences on consumers’ satisfaction and re-purchase intention, while risks from transaction cost affect only satisfaction. Moreover, risks perceived from product performance were even found to have positive impact on re-purchase intention. Our study provides insights into how different sources of perceived risk influence consumers’ purchase behavior DOI: http://dx.doi. org/10.5755/j01.ee. 26.3. 8420
Utilization of Value Stream Analysis to Implement Redefined Value: A Social Business Perspective

The premise of value focuses on the customer while the integration of social and environmental value along with customer value holistically is missing. This paper redefines the conceptualization of value as a three dimensional construct encapsulating customer, social and environmental (CSE) value. Furthermore, in operations management, value stream analysis (VSA) has been utilized as an implementation tool of customer value only. However, this study addresses a gap in the literature by employing VSA as an implementation tool to execute the redefined CSE value in a social business setting. An exploratory research driven by semi-structured interview sessions with the employees of a social business in Bangladesh were conducted while embracing a qualitative research strategy to build new insights and theories. In consequence, this study offers strategic suggestions to existing social businesses as to how the redefined conceptualization of value can be implemented for the betterment of customer, society and environment.
