"This book provides a comprehensive review of the efforts put forth by China to prevent food safety concerns, including the abuse of food additives. Looking at food producers and operators, consumers, and government agencies as part of an organic system, the book examines the complete system of the food supply chain from multi-scientific systematic points of view. It begins with the production of agricultural products and investigates the changing track of food safety (including imported and exported products) in the key aspects of production, circulation, and consumption between 2006 and 2011"--

Steganography is the art of secret communication and steganalysis is the art of detecting the hidden messages embedded in digital media covers. One of the covers that is gaining interest in the field is video. Presently, the global IP video traffic forms the major part of all consumer Internet traffic. It is also gaining attention in the field of digital forensics and homeland security in which threats of covert communications hold serious consequences. Thus, steganography technicians will prefer video to other types of covers like audio files, still images or texts. Moreover, video steganography will be of more interest because it provides more concealing capacity. Contrariwise, investigation in video steganalysis methods does not seem to follow the momentum even if law enforcement agencies and governments around the world support and encourage investigation in this field. In this paper, we review the most important methods used so far in video steganalysis and sketch the future trends. To the best of our knowledge this is the most comprehensive review of video steganalysis produced so far.

Suicide is difficult to predict and prevent and remains a leading cause of death worldwide. Although soldiers historically have had a suicide rate well below that of the general population, Indian Army, being the largest among the three forces, witnessed the highest number of suicides has increased markedly over the past several years. As many as 116 army personnel committed suicide in 2010. The figure offers some respite for the army top brass and the Indian government as the number of suicidal deaths witnessed a decrease with 86 suicides reported in 2013. From an all-time high of 129 in 2006, the number of suicides by armed personnel had dipped to 86 in 2013 and rose again to 108 in 2014.

Onwuegbuzie and Frels (2015) provide the framework for evaluating current research and present seven steps for developing a Comprehensive Literature Review. Today a significant dilemma of research involves the sparse number of rigorous, empirical research studies to guide development of best practices of writing. The authors describe the purpose of their book as "a tool and guide for master's-level students, doctoral-level students, and new and experienced researchers" to approach writing a CLR in a through and investigative way. The thrust and challenge is for researchers to concentrate on improving their methods and practices when reviewing topics with strong potential for shaping long-term educational policies.

Since 1990 the number of glanders outbreaks in race, military and pleasure horses in Asia and South America is steadily increasing. Glanders, which is eradicated in Western Europe, Australia and Northern America, is currently considered a re-emerging disease. Consequently, the disease may be introduced into glanders-free regions by subclinical carriers at any time. The causative agent of glanders, Burkholderia (B.) mallei, is highly contagious and leads to chronic disease in horses whereas in donkeys and mules the disease is acute and often fatal. Occurrence of the disease leads to international trading restrictions and infected animals immediately have to be culled and safely disposed off. In humans B. mallei infection results in a severe clinical course, and is fatal without appropriate therapy. Its pathogenicity makes B. mallei a potential biological agent that may be used in bioterroristic attacks. Due to the eradication of glanders in the second half of the last century, veterinarians in western European countries are no longer familiar with its clinical presentation in solipeds. Having these facts in mind, this review describes the epidemiology, clinical signs, pathology and the current eradication strategy of this interesting zoonosis. Pictures of imported endurance horses infected with glanders taken during an eradication campaign in Dubai, United Arab Emirates, in 2004 illustrate most typical clinical findings

PurposeThe purpose of this paper is to provide a comprehensive literature review of enterprise content management (ECM) research, a conceptual framework of areas of concern regarding ECM, and an agenda for future ECM research, based on the review and conceptual framework.Design/methodology/approachTo gain an understanding of the ECM literature, a structured research approach is adopted, consisting of two phases. The first phase consists of identifying the relevant ECM research papers. In the second phase, the analysis phase, the current ECM research is categorized based on three structural pillars: system component dimensions, system lifecycle, and strategic managerial aspects.FindingsAfter a review and classification of 91 ECM publications, it is found that ECM involves several sophisticated and interacting technical, social, organizational, and business aspects. The current ECM literature can be grouped around three main pillars: the first pillar consists of the four ECM component dimensions (tools, strategy, process, and people). The second pillar is the enterprise system lifecycle (adoption, acquisition, evolution, and evaluation). The final pillar is the strategic managerial aspect (change management, and management commitment). Based on the review and a proposed conceptual framework, an agenda for future research around the aforementioned three pillars is suggested.Originality/valueThere is a lack of ECM meta‐analysis research that explains the current state of the field. This paper contributes to information systems research by describing and classifying the published literature in ECM and by pointing out the gaps where further research is most needed. Furthermore, the paper provides a framework that may provide a conceptual structure for future studies.

"This text aims to provide information for naturalists, concerning the biota of the Caucasus, through its biomes, amd refugial areas and habitats. The work is focused on supplying a datebase for the current presence and distribution of many speceis, with an emphasis on the keastone species, the existance and range of which face major challenges and threats today, caused primarily by human's direct and indirect activity, and global warming. The book incorporates the most recent taxonomic ranking of plants and animals species in the Caucasus, and the regularity and history of its biomes, among other topics. The monograph is also heavily illustrated with mostly original color photos, which reinforce the scientific quality of the text. This book will be of great interest to scholars of life and earth sciences and geographers. As an interdisciplinary work, the monograph provides students of all levels with valuable information on the environmental sciences, which may isnpire them to pursue this topic within natural science, stimulating their research and career choices"--
