Empirical Measurement (empirical + measurement)
Selected AbstractsMarching toward a Harmonious Society: Happiness, Regime Satisfaction, and Government Performance in Contemporary Urban ChinaASIAN POLITICS AND POLICY, Issue 3 2009Diqing Lou This study examined the happiness of citizens in urban China. Empirical measurements were made of the relationship of reported happiness to economic variables, as well as to citizens' satisfaction with government policies. Employing the 2002 Asian Barometer Survey and the Amelia statistical software package, I found that happiness is strongly correlated both to absolute economic conditions and to relative economic status. Furthermore, citizens who perceived government policies as being responsive to their needs were more likely to report a high level of personal well-being. This empirical analysis confirms the direction of Chinese leader Hu Jintao's development strategy, which seeks to promote widespread economic prosperity among Chinese citizens. The study results indicate that a healthy and balanced economy is essential in improving urban happiness in China. Based on these results, I argue that the Chinese government can further improve citizen happiness by providing ample employment opportunities and promoting progressive housing policies. [source] Explaining isotope trophic-step fractionation: why herbivorous fish are differentFUNCTIONAL ECOLOGY, Issue 6 2007A. C. MILL Summary 1An assumed constant trophic fractionation of 15N/14N between consumer and diet (usually 3·4 for diet,muscle tissue differences) allows inferences to be made about feeding interactions and trophic level in food web studies. However, considerable variability surrounds this constant, which may conceal subtle differences about the trophodynamics of consumers. 2The feeding ecologies of herbivores and carnivores differ in terms of diet quality (in C : N terms) and food processing mechanisms, which may affect fractionation. 3We present a new model that explores how consumer feeding rates, excretion rates and diet quality determine the 15N/14N ratios in the consumer's tissues and hence influence the magnitude of trophic fractionation. 4Three herbivorous reef fish Acanthurus sohal, Zebrasoma xanthurum and Pomacentrus arabicus were chosen as study organisms. Empirical estimates of diet,tissue stable isotope fractionation were made in the field, and model parameters were derived from feeding observations and literature data. 5The trophic fractionation values of A. sohal, Z. xanthurum and P. arabicus were 4·69, 4·47 and 5·25, respectively, by empirical measurement, and 4·41, 4·30 and 5·68, respectively, by model, indicating that herbivores have a higher trophic fractionation than the currently accepted value of 3·4. 6The model was most sensitive to the excretion rate, which may differ between herbivores and carnivorous animals. This model is the first to determine stable isotope signatures of a consumer's diet mixture without applying a constant fractionation value. [source] The Dynamics of Ethnic FragmentationAMERICAN JOURNAL OF ECONOMICS AND SOCIOLOGY, Issue 2 2005A Proposal for an Expanded Measurement Index This paper identifies problems associated with the current empirical measurement of ethnic diversity in economic development literature. An expanded index of ethnic diversity is proposed to include variables such as religion and race, and the results are compared to the prevailing index utilized in empirical literature. The mean of the proposed index is significantly larger and the standard deviation is significantly smaller than that of the prevailing index. This would suggest that disparities in ethnic diversity among countries are not as wide as previously assumed. Further, these results confirm that a comprehensive and more accurate measure of ethnic diversity requires more than a linguistic measurement, which is the primary factor utilized in the prevailing index. [source] Unmet Need for Family Planning in Developing Countries and Implications for Population PolicyPOPULATION AND DEVELOPMENT REVIEW, Issue 4 2000John B. Casterline Unmet need for family planning has been a core concept in international population discourse for several decades. This article reviews the history of unmet need and the development of increasingly refined methods of its empirical measurement and delineates the main questions that have been raised about unmet need during the past decade, some of which concern the validity of the concept and others its role in policy debates. The discussion draws heavily on empirical research conducted during the 1990s, much of it localized, in-depth studies combining quantitative and qualitative methodologies. Of the causes of unmet need other than those related to access to services, three emerge as especially salient: lack of necessary knowledge about contraceptive methods, social opposition to their use, and health concerns about possible side effects. The article argues that the concept of unmet need for family planning, by joining together contraceptive behavior and fertility preferences, encourages an integration of family planning programs and broader development approaches to population policy. By focusing on the fulfillment of individual aspirations, unmet need remains a defensible rationale for the formulation of population policy and a sensible guide to the design of family planning programs.
