The study of national or national history has achieved comprehensive development in social science research，Where，Focus National Chronicle Research has been highly respected in many research fields in recent years。Associate Professor of the Institute of Labor Research, Barcelona, ​​Spain, Joan Miquel Verd and others recently published in the "field method" journal，Combining the focus of focus ethnic aspect with case research，It will produce better research effects。This combination can not only improve data quality and comparative research ability，It will also improve the transformation of the research results。

Beld and others think，Focus ethnic history can be understood as a specific type of ethnic evaluation method or evaluation program。In literature research，This method is also called mini nationality、Micro bet365 best casino games -ethnic Chronicle, etc.。

The fields where the focus of the nation is infiltrated is becoming more and more extensive。For example，In Nutrition and Health Anthropology，People are committed to determining the economy that affects diseases and nutrition、Social and cultural factors，Design more effective intervention measures。In terms of health care，People from different cultures and social groups integrate health concepts and practice into their own life。

Focus National Chronicle does not conflict with mainstream national ideas。Beld and others think，Focus ethnic methods are sometimes alternative to other traditional national ideas，Sometimes it can be used as a supplement。In traditional national methods，Data is usually obtained through direct contact with the research group。Researchers will carry out field survey projects for a long time，Through interview、Participate in observation、Literature analysis and other methods to make detailed and accurate descriptions。Comparison of comparison，Traditional national history pays more attention to the overall judgment of the cultural values ​​and Bet365 lotto review common behaviors of a certain group;、Similar questions，Ru exchanges、Feeding behavior、Technical use, etc.。

Beld and others think，If you want to obtain high -quality research results with the focus of the national history，The research focuses on the several variables that start to be determined。On the process，Focus on the field survey of researchers for national history is mainly short -term stay，But pay more attention to the strict collection of data。Focus in the field of health is mostly for data collection through interviews，And anthropology or sociological scholars mainly use direct observation methods。This method stripped away the strong personal immersion of researchers in the traditional national history method of research group or community，Therefore, pay more attention to in -depth analysis of large amounts of data。other，During the data collection or data analysis phase，Compared to the individual independent work commonly used in traditional national ideas，Focus ethnic history adopts a collective work method。

　　Case Study Method Optimize Focus National Chronicle Research

Focus ethnic methods bet365 Play online games and case research methods are usually separated in existing research，Dan Beld and others think，From the definition or practice of nationality，Both can have a closer combination。

Case Study，Design phase before data collection，Researchers need to establish an open basic theoretical proposition based on existing theoretical knowledge。Propositions need to predict the vision of the problem research on the problem、Determine which data can respond to research problems，and ensure that the selected cases or analysis units are as correlated as possible。So，Use existing theoretical knowledge，You can ensure the representativeness of the sample in advance，Therefore, it is found to be found to the selected specific case。At the same time，When involving multiple cases，Theoretical knowledge is often used in the selection of comparative cases or control cases。

Beld and others proposed in the text，Case research method has interpretation or traceability，This means that theoretical knowledge plays an important role in it。The integration of the methodology level will introduce a research concept in the focus national bet365 Play online games history，The choice and comparison of the case will be driven by the existing theoretical knowledge，This will bring a series of benefits。

Focus National Chronicle Research usually goes with expansion or improvement of a theory，Demand with theoretical innovation。Studies currently using the focus of the focus of the national history do not attach importance to the basis of the theoretical knowledge as the case selection，Do not pay attention to the concept of obtaining comparative cases or control cases。

Case Studies The characteristics of method design can strengthen the many advantages of the focus of the national chronth。Beld and others said，When the case studies are selected and compared with the case based on the theoretical goals in the design stage，The focus of the focus of the national aspirations included in it is a clarity、Focus on the research departure，This integration may bring a series of benefits。Researchers can get enough theoretical information，Determine the key elements required by the institute in advance。

Beld and others summarize the role of integration as follows: First of all，bet365 best casino games Decisions driven by theory ensure that the selected case is not isolated or special，Ensure that their representativeness of the research objects。Next，The theoretical correlation of the collected data is guaranteed。other，Case comparison makes the effect of the explanatory factors be controlled，Make research can provide strong conclusions。Last，Optimized due to the analysis of the research results，Therefore, the realization of the research results in external promotion or transformation。
