Carino BV 《The International migration review》1987,21(4):1,265-1,269
The author reviews migration data sources and government collection agencies in the Philippines. He finds that "despite the importance of international migration for national policy, efforts to correct the serious data limitations in the area of migration statistics have been limited and uncoordinated. In fact, most estimates of emigration levels from the Philippines still rely heavily on the data gathered by receiving countries." 相似文献

This study examines the impact of race and ethnic group on the integration of immigrants into the labor force in Canada. A distinction is made between migrants who are free to change jobs at will and those bound by legal and other constraints from so doing. The examples of agricultural and domestic workers are chosen to illustrate how the different types of migrants are incorporated into the country's production relations. (SUMMARY IN FRE AND SPA) 相似文献

This paper considers the application of Stein-type estimation procedure for the coefficients in a linear regression model when data are available from replicated experiment. Two families of estimators characterized by a single scalar are proposed and their large sample asymptotic properties are derived. These are utilized for comparing the performances of the two estimators along with the conventional estimator and conditions for the superiority of one estimator over the other are deduced. 相似文献

Barry V. Johnston 《The American Sociologist》1998,29(3):26-42
The history of sociology is marked by periods of theoretical pluralism and hegemony. Their interplay has resulted in the slow
and uneven development of the discipline. Today, however, bodies of theory and practice have become so diverse that many scholars
worry that sociology is in a state of disintegration. The theoretical career of Talcott Parsons provides a microcosm in which
to explore similar processes. Building on the success of The Structure of Social Action, Parsons led a movement that transformed Harvard's Department of Sociolgy into the Department of Social Relations. There
he attempted a grander, but failed synthesis in Toward A General Theory of Action. His case provides a situation in which to explore features of disciplinary integration and fragmentation. The comparison
stimulates one to fashion an informed sense of whether sociology is now facing its latest crisis or may be in the process
of decomposition as a corpus of study.
This research was supported by grants from the American Sociological Association's Fund for the Advancement of the Discipline
and by Indiana University Northwest through a sabbatical leave. 相似文献

Mindanao is the second largest island in the Philippines. Once considered the greenest spot on earth, it has since been highly exploited. This paper discusses the changing ecosystem of the island as a result of rapid population growth since the early 1900s. Not much is known about Mindanao before 1900. From 1913, however, population grew on Mindanao as the American colonial government established agricultural colonies to open up the south for trade and development. Colonial settlement together with migration and natural population increase led to environmental resource degradation and the displacement of indigenous communities such as the Moros and Lumads. Legal and illegal logging and rampant kaingin agriculture have also stressed the environment. The opening of the Mindanao frontier, Philippine development, the Great Migration, incursion of the Mindanao upland, deforestation, the displacement of indigenous communities, and the possible maintenance and rehabilitation of the ecosystem are discussed. 相似文献

Rethinking assimilation theory for a new era of immigration 总被引:6,自引:0,他引:6
"We argue that assimilation theory has not lost its utility for the study of contemporary immigration to the United States. In making our case, we review critically the canonical account of assimilation provided by Milton Gordon and others; we refer to Shibutani and Kwan's theory of ethnic stratification to suggest some directions to take in reformulating assimilation theory. We also examine some of the arguments frequently made to distinguish between the earlier mass immigration of Europeans and the immigration of the contemporary era and find them to be inconclusive. Finally, we sift through some of the evidence about the socioeconomic and residential assimilation of recent immigrant groups. Though the record is clearly mixed, we find evidence consistent with the view that assimilation is taking place, albeit unevenly." 相似文献

The validity of a survey's findings is dependent upon the clarity and lack of ambiguity contained in each individual item yet minimal attention has been directed to this issue in most prevalence studies. Researchers have shown a tendency to accept the uncritical assumption that respondents interpret seemingly simple and straightforward items such as 'how much do you spend gambling?' in a consistent manner. No attempt is made to confirm the uniformity of responses by clarifying the mathematical formulae used by respondents to derive their answers. The purpose of this paper was to examine the consistency shown by a sample of 181 medical undergraduate subjects in estimating the level of gambling expenditure in a series of five case vignettes describing various scenarios of wins and losses during a session of gambling. Results revealed a wide variation in calculated figures depending upon whether or not subjects interpreted the item to mean net expenditure or turnover. Only two thirds or less of subjects calculated the figure to be the difference between the initial amount risked and the residual at the conclusion of the session. It is suggested that more attention be paid in prevalence and clinical studies to providing subjects with clear instructions on how to calculate expenditure estimates. 相似文献

Research guidelines are proposed for the study of long-term marriages based on a critical review of existing studies. Current problems in the collection and analysis of the data include the lack of agreement about the minimum length of a long-term relationship, the failure to make couple comparisons, or to follow samples longitudinally. In addition, the response rate is uniformly low and the variables studied are not consistent. Future research should gather data about couples, not just individuals, and should utilize standardized measures. It is important to begin to build a comprehensive and comparable data base of long-term marital relationships. 相似文献
