In non-experimental research, data on the same population process may be collected simultaneously by more than one instrument.
For example, in the present application, two sample surveys and a population birth registration system all collect observations
on first births by age and year, while the two surveys additionally collect information on women’s education. To make maximum
use of the three data sources, the survey data are pooled and the population data introduced as constraints in a logistic
regression equation. Reductions in standard errors about the age and birth-cohort parameters of the regression equation in
the order of three-quarters are obtained by introducing the population data as constraints. A halving of the standard errors
about the education parameters is achieved by pooling observations from the larger survey dataset with those from the smaller
survey. The percentage reduction in the standard errors through imposing population constraints is independent of the total
survey sample size. 相似文献

Attitudes of Italian heterosexual men and women toward gay men, both HIV positive and negative, are poorly investigated. Italian culture is still extremely conservative and provides limited support to the gay community (e.g., lack of same-sex marriage recognition). Consequently, gay men experience social exclusion and disparities. The present study explores the association between homophobia and closeness with sexual orientation and HIV status. 261 heterosexual Italian men and women were assessed for feelings of closeness and homophobia after reading a vignette where the character was C1: heterosexual and HIV negative; C2: gay and HIV negative; or C3: gay and HIV positive. Experiences of homophobia and closeness varied depending on gender of participant and condition assigned, and higher levels of homophobia were correlated with lower levels of closeness regardless of HIV status. Implications and future directions are discussed. 相似文献
ABSTRACT The subject of this paper is the relationship between female labour force participation, fertility decisions and marital instability and pursues a two-fold objective: to explain the nature of the interdependences between participation and procreation decisions; and to look for, through empirical evidence, an explanation for women's labour force participation and fertility dynamics over the last 20 years. The empirical evidence, based on a panel of 19 countries over the period 1965–1989, shows that variables representing marital instability have an important role in woman's labour supply and fertility dynamics during this period. 相似文献
We study the impact of emotions on real-world decisions made by loan officers by analyzing the loan conditions of loans granted immediately after a bank branch robbery. We find significant differences between the conditions of loans granted after a robbery and changes in loan conditions that occur contemporaneously at unaffected branches. In general, loan officers seem to adopt so-called avoidance behavior. In accordance with the literature on posttraumatic stress, their avoidance behavior is halved within 2 weeks following the robbery and the effect further varies depending on the presence, or absence, of a firearm during the robbery.

This paper uses recent multidimensional well-being measurements to examine multidimensional well-being and inequality across the European regions in 2000 and 2014 with the use of eleven well-being indicators from the OECD Better Life Index. We use generalized mean aggregation method with alternative parameters to allow different substitutability and complementarity levels between well-being dimensions, which range between perfect substitutability and some degree of complementarity between the dimensions, to examine well-being and inequality across the European regions. Accounting for the interactions between the well-being dimensions matters for the multidimensional well-being and inequality across the European regions. The results show that the multidimensional well-being across the European regions are relatively lower when the dimensions are more seen as complements compared to the case when they are considered to be perfect substitutes. Furthermore, there is also a higher degree of multidimensional inequality across the European regions when the dimensions are considered to have some complementarity. Changes in well-being dimensions between 2000 and 2014 indicates that multidimensional well-being improved and inequality decreased in the personal and community well-being categories, but remained unchanged in material well-being category across the European regions irrespective of interaction levels between well-being dimensions. Policy implications of these multidimensional well-being indices are also evaluated by using these indices to determine the eligible regions for the European Union structural funds where the number eligible regions shows some variation depending on whether the dimensions are perfect substitutes or more of complements.
Partial Order Theory has been recently more and more employed in applied science to overcome the intrinsic disadvantage hidden
in aggregation, if a multiple attribute system is available. Despite its numerous positive features, there are many practical
cases where the interpretation of the partial order can be rather troublesome. In these cases the analysis of underlying dimensions
could be useful to uncover particular data structures. The paper shows a way of addressing the problem with the help of an
actual case study, which deals with European opinions on services of general interest. In particular, a partial order of countries
is firstly provided and then a method to detect dimensions is discussed and applied. The analysis stems directly from the
Partially Order Set (poset) and Lattice theory with particular references to dimension theory and Formal Concept Analysis.
The study is eventually able to pinpoint role and relevance of different attributes characterizing EU countries which are
used to define the partial order.
Even though the millennium development goals (MDGs) tackle the main economic and social problems in developing countries,
nutrition is not addressed adequately despite its important role in achieving the MDGs. It is therefore crucial to mainstream
nutrition by strengthening public-private partnerships, increased political and technical capacity and by achieving food security.
The paper aims to discuss how strong partnerships bringing public and private efforts together are important to the success
of increasing nutritional programs by providing a redesign and marketing of products and services, other services, and funding.
The report explores the need to assess the setting of pertinent nutritional policies and to increase technical capacity. The
study found that the relation between agriculture and nutrition is a key component for achieving food safety in order to mainstream
nutrition into the MDGs. The three main topics considered in this analysis are biotechnology, food trade policies, and bioenergy
products as they have a strong impact on prices. Mainstreaming Nutrition for better development outcomes.
This study investigated the development of the pointing–vocal coupling system. We were interested in the infants’ behavior to attune prosody with pointing intentions. Twenty‐five children were involved at 12, 15, and 18 months of age in an experimental procedure devised to elicit imperative and declarative pointing. Pointing, vocality associated with pointing, and the prosody of that vocality were analyzed. A significant increase in the coupling of pointing and vocality was observed from 12 to 15 months, and in the ability to differentiate prosody with respect to the intention of the gesture from 15 to 18 months. Also, the infants who pointed declaratively at 12 months were likely to couple declarative pointing with vocality at 15 months, and the infants who coupled at 15 months were likely to differentiate prosody by the pointing intention at 18 months. Results suggest that the match between prosody and pointing intentions emerges gradually during the first half of the second year of life. They also show a relationship between earlier and later pointing–vocal coupling, and a role for declarative communication in promoting that progression. Overall, our study supports the view of intentional communication as a time‐based and context‐based developmental process. 相似文献
