Most demographic studies use 2,500 grams of birth weight and 37 weeks of gestation as cutpoints for evaluating the effects of adverse birth outcomes on infant mortality. We propose an alternative strategy, which relies on continuous measures of birth outcomes, identifies an optimal combination of birth weight and gestational age for infant survival, and estimates the effects of adverse birth outcomes in terms of their departure from this "optimal point." We illustrate the advantages of this approach by estimating a logistic model using data from the 1989-1991 NCHS linked birth/infant death files. Finally, we discuss future applications and methodological issues to be resolved in subsequent research. 相似文献

ABSTRACTDrawing on my experience as a queer, genderqueer, Puerto Rican counselor educator, this article considers how LGBTQAI+ studies and academia can expand to better include people with multiple marginalized identities. This article highlights some of the contradictions that educators face when engaging in the liberatory praxis that connects and creates a sense of belonging during these tumultuous times. This reflection suggests a decolonizing approach to intersectionality and highlights the importance of transcending binary discourse to engage in deconstructing the multiple layers of colonization in our internal and external spaces that is necessary for liberatory praxis. Finally, a few recommendations for how LGBTQAI+ studies and academia can support scholars with multiple marginalized identities are identified. 相似文献

This study aimed to examine the gender-related differences in demographics, gambling measures, psychological functioning,
and motivation for therapy in an outpatient sample of pathological gamblers seeking treatment. Participants in this multisite
study included 103 adult outpatients (51 women and 52 men) meeting current DSM-IV-TR criteria for PG. Logistic regression
was used to examine if gender was related together to categorical and continuous independent variables. Female gamblers were
older than men and more likely to be divorced or widowed and to have a lower annual income. Women became more dependent on
bingo and men on slot machines. Gambling motivation and the course of illness for both sexes were also different. Female gamblers
were more anxious and with a poorer self-esteem than male gamblers and more affected by depressive symptoms; in turn, men
were more impulsive and higher sensation seekers than women and more affected by drug/alcohol abuse. The 68.6% of female gamblers
reported being victims of intimate partner violence. There were no gender differences about the motivation for treatment.
Future research should examine gambling behaviors and psychological functioning and suggest treatment approaches to address
specific goals according to these gender-related differences. 相似文献

This paper contributes to the literature on the effect of venture capital (VC) on the economic development of areas in which those specialized investors are active. The work focuses on the separate consideration of two effects that are supposed to explain the superior performance of a large sample of Spanish VC-backed firms, namely funding and value-added services provided by VC managers to their investee firms. The results show that funding is significant regardless of the stage of development of the investee firm. The value added, however, is only significant for the subsample of firms at the expansion stage. 相似文献

This study analysed, from a social justice perspective, how students from two Chilean public schools evaluate, legitimise and delegitimise processes and social actors associated with classroom well-being. Using a participatory qualitative design, fifty-nine (59) seventh grade students were asked to take and then select photographs about their school experience, and later participated in semi-structured interviews and a group workshop. Findings regarding the classroom context showed that children legitimised active learning methodologies, teachers to whom they feel close, and the use of technology for learning. They delegitimised punishment and teachers who ignored minority students or those with learning difficulties. 相似文献

We introduce a new centrist or intermediate inequality concept, between the usual relative and absolute notions, which is
shown to be a variant of the α-ray invariant inequality measures in Pfingsten and Seidl (1997). We say that distributions
x and y have the same (x, π)-inequality if the total income difference between them is allocated among the individuals as follows: 100π% preserving
income shares in x, and 100(1−π)% in equal absolute amounts. This notion can be made as operational as current standard methods in Shorrocks
(1983).

We present here a direct elementary construction of continuous utility functions on perfectly separable totally preordered
sets that does not make use of the well-known Debreu’s open gap lemma. This new construction leans on the concept of a separating
countable decreasing scale. Starting from a perfectly separable totally ordered structure, we give an explicit construction
of a separating countable decreasing scale, from which we show how to get a continuous utility map.

Innovation is nowadays a fundamental determinant of value creation in business companies and economic growth. Therefore, the measurement of innovation has become a significant concern both for business companies and governments. Traditionally, attempts to measure innovation have adopted a macroeconomic approach, as they have been largely based on broad surveys. However, no attempt has been made to date in order to complement the information provided by such surveys with aggregated data obtained from the financial reports of individual companies. This paper analyses the conceptual and methodological problems underlying the measurement of business innovation by means of surveys and discusses the lack of ability of accounting standards to accurately reflect innovative activities in the financial statements of business firms.In the light of the evidence provided by the empirical studies published to date, we analyse the Spanish situation by reviewing innovation studies conducted by the National Institute of Statistics (INE), and assessing the relationship between the value relevance of accounting information and the firm's technological level. Our results suggest that both, micro- and macroeconomic approaches towards the measurement of innovation have significant shortcomings. Thus, a joint effort seems to be needed in order to overcome the methodological limitations affecting innovation studies based on surveys and those relying on financial accounting information. Despite their limitations, surveys provide a sound basis for the identification of trends, key factors and explanatory variables. On the other hand, financial statements could provide a sound basis for the measurement of innovation if they included more relevant information on the intangible determinants of the value of companies. This has obvious implications for the standard setting process. 相似文献
