Migration data collection within Russia has significantly improved in recent years. A set of laws and administrative decrees launched in 2002-2010 have updated the system of migrant registration and have improved communication channels between data collecting administrative bodies (Ministry of Interior, Federal Migration Service, Border Service, etc.) and the Federal Statistical Service of the Russian Federation (Rosstat). In 2009, the elaboration of the Integrated System of Migration Data (Gosudarstvennaya Informatsionnaya Systema Migratsionnogo Ucheta - GISMU) was finalized. Its core is the Centralized databank on foreign nationals (Centralny bank dannykh ucheta inostrannykh grajdan - CBDUIG) that carries both personal and statistical information. Collection of migration data focuses mainly on migrants' flows, while data on migrant stocks are an object for population censuses only. Russian statistical sources usually separate data on migration exchange with the post-Soviet countries (CIS & Baltic countries and Georgia) (novoye zarubejye) from data on all other countries (staroye zarubejye). This division is fundamental because of differences in migration flows between Russia and the two groups of countries in terms of nature, scale, structure, as well as the migration regulations applied. ; Consortium for Applied Research on International Migration (CARIM-East) is co-financed by the European University Institute and the European Union

This book contains twelve selected papers presented at the International Workshop on Traffic Data Collection and its Standardization held on September 8-9th 2008 in Barcelona. Organized and chaired by Barcelo and Kuwahara, the workshop was intended to examine the purposes and quality of data and how it is collected and used in traffic analysis, with the overall intent of improving and standardizing the practice. Traffic data is the cornerstone to everything from the most classical traffic control analysis to the most advanced real-time control and management implementing modern Intelligent Transportation Systems (ITS) applications. These applications are primarily based on the availability of traffic data supplied by a Data Collection System which, equipped with more or less sophisticated technologies, provides measurements on the fundamental traffic variables, ideally with the required level of temporal aggregation, and perhaps, when the technology allows it, additional measurements on other variables of interest, depending on the type of application in which they will be used. The applications are in turn supported by models, and in fact the primary use of the data is to provide the input to traffic models whose quality depends on the quality, consistency, robustness, completion and other characteristics of the data.

The national recording system for international migration in Georgia is essentially unregulated. This is due both to the complexity of migration registration and by the grave situation in the country at the time of statistics reform in Georgia. Unfortunately, in the post-Soviet years, with economic collapse and political chaos statistical registration in the country was disrupted and even if social and economic recovery started only recently there, statistics were not relevant to the contemporary situation. As to migration flows, the strict registration of people?s movement was still in effect in the first years of the post-Soviet period. Statistical services received tags from so-called ?registration sheets.? Migrants could not change their place of residence without applying to the passport service of the Ministry of Internal Affairs. Liberalization of people?s movement given the absence of a population register made the process of registration unmanageable. Today, few changes have been implemented to improve the data collection system. The legal basis of official statistics is extremely weak. The current law on statistics is a copy of other countries? laws. It is imperfect and does not provide the necessary information, not allowing that information to be obtained or processed properly. The abolition of statistical services in administrative regions in order to ?economize? on staff and to reduce expenses on statistics substantially worsened the obtaining of primary statistical information being Georgia characterized by sharp regional differences. It is unfortunate that current statistical service is more oriented to the demands of consumers outside the country. The statistics reflecting the situation inside the country does not come close to the demands of scientists Linkages between the Department of Statistics of Georgia and academic circles are very weak. Against a background of general reforms, the reforms made in the system of statistics are ineffective. Its personnel are few and frequently poorly motivated. It is obvious that the statistical service is in need of legal, organizational and structural reform with functional expansion and better human resources. ; Consortium for Applied Research on International Migration (CARIM-East) is co-financed by the European University Institute and the European Union

Modernizing Financial Data Collection with XBRL

Sensor nodes have limited processing power, small storage capacity and limited energy. These constraints make classical security algorithms unsuitable for WSNs (Wireless Sensor Networks). Therefore, new techniques that consider these limitations are needed. WSNs have a wide range of applications, including military field surveillance, healthcare, homeland security, industrial control, and intelligent green aircraft. Therefore, network security has become increasingly important. There are various types of attacks that may cause security problems, such as modification attacks and selective forwarding attacks. This thesis investigates three security problems in WSNs. Firstly, we investigate the problem of minimizing the failure rate of packet delivery in the presence of modification attacks and selective forwarding attacks in a static WSN with one base station without using expensive encryption/decryption algorithms. We propose a novel heuristic approach to this problem. Our approach is based on randomized multipath routing. Secondly, we investigate the problem of constructing a shortest path overhearing tree with the maximum lifetime for data collection. We propose three approaches for homogeneous WSNs and heterogeneous WSNs. The first one is a polynomial-time heuristic approach. The second one uses ILP (Integer Linear Programming) to iteratively find a monitoring node and a parent for each sensor node. The last one optimally solves the problem by using MINLP (Mixed- Integer Non-Linear Programming). Lastly, we investigate the reliable and secure end-to-end data aggregation problem considering selective forwarding attacks and modification attacks in homogeneous cluster-based WSNs, and propose three data aggregation approaches which can defend against both modification attacks and selective forwarding attacks. Our approaches use secret sharing and signatures to allow aggregators to aggregate the data without understanding the contents of messages and the base station to verify the aggregated data and retrieve the ...

National statistics (official data) in Ukraine on migration issues include state statistics, such as information collected by the State Statistics Service of Ukraine and ministerial statistics, and data collected by the ministries and state agencies on given aspects of migration. Here and below all the institutional establishments in Ukraine are listed under their current names: in April 2011 a complete reorganisation of these authorities was made, and a number of establishments were renamed or combined with other establishments. In 2012, the Ministry of Revenue and Duties of Ukraine was established by a merging of the State Tax Service and the State Customs Service of Ukraine. In 2013, the Ministry of Education and Science, Youth and Sports of Ukraine was divided into the Ministry of Education and Science of Ukraine and the Ministry of Youth and Sports of Ukraine. ; Consortium for Applied Research on International Migration (CARIM-East) is co-financed by the European University Institute and the European Union

Data collections and acquisitions in the electronic age are increasingly unique globally. But the growing equity in access to data for effective information service delivery and global relevance is a serious import of this study. Therefore, the effect of current economic and political challenges in Nigeria to the community of data, and the need to bridge the gap in literature is imperative. The purpose of the study is to determine the extent to which health libraries in the South-West, Nigeria have formalized data collections and acquisitions in the electronic age and to highlight the guidelines and policies used for collection and acquisition in the electronic age as against the traditional purchasing models. And, to determine the extent of current challenges on collection development and acquisitions for improve access to relevant data. There are scores of medical/health libraries in the south west of Nigeria but the guidelines for collections and acquisitions for effective information service delivery is underdeveloped. Giving the growing importance of this study, a questionnaire and interview approach will be explored to gather data from the Sectional heads and the Medical/Health Library Directors.

This article provides an innovative meta-framework comprising strategies designed to guide qualitative data collection in the 21st century. We present a meta-framework comprising strategies for collecting data from interviews, focus groups, observations, and documents/material culture. We present a template for collecting nonverbal data during interviews and discuss the concept of debriefing the interviewer. We identify types of data that can be collected in focus groups in addition to the actual statements made by the participants and provide templates for categorizing these data. Also, we outline the role that social networking websites can play in focus group interviews. Further, we provide models for observations that include photographs and videos. Finally, we outline ways of accessing and collating documents/material culture that can be used for document analyses.
