This cross-sectional, secondary analysis study utilizes data from a prior study of intergenerational substance use among Latina women (n = 316). We explored the influence of substance use frequency and type, as well as cultural and socioeconomic factors on attributions about addiction among a predominantly immigrant sample of Latina women. Women who were less proficient in English (an indicator of adoption of the receiving culture in the acculturation process) and more proficient in Spanish (an indicator of heritage-culture retention) endorsed more spiritual model attributions than women who were more proficient in English and less proficient in Spanish. Women were more proficient in Spanish more frequently endorsed the disease attribution model. Alcohol, marijuana use and non-medical sedative use were linked with spiritual, moral /character and disease attribution models respectively. Participants reporting higher education levels indicated less agreement with the moral/character model of addiction. Implications for culturally tailored social work interventions for Latina women are discussed. 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

Adoption in Brazil has long been related to practices of not disclosing the child's history and origins, which become a family secret. As a consequence, most couples who apply for adoption prefer newborns. Late adoption is still an uncommon practice and requires a 'family project' which accepts a different family model, new meanings of motherhood and fatherhood, and different ways of building affectionate bonds. It is important to investigate how a man and a woman become parents under those circumstances. This study aimed to follow up the emergence of adoption, motherhood and fatherhood meanings, in the discursive practices involved in the construction of adoptive parenthood in the Brazilian setting. This paper presents important meanings regarding parenthood produced by a couple who adopted two sisters, aged 4 and 5 years. Analysis revealed that to better understand the late adoption process, the meanings that emerge in the discursive practices should be considered. Those meanings pervade and circumscribe the family relationships, influencing how the individuals constitute their roles in the family. It is through the analysis of this dialogical process of construction that it is possible to identify the challenges in late adoption and to unravel the process of constructing affectionate relationships. 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

Industrial statistics plays a major role in the areas of both quality management and innovation. However, existing methodologies must be integrated with the latest tools from the field of Artificial Intelligence. To this end, a background on the joint application of Design of Experiments (DOE) and Machine Learning (ML) methodologies in industrial settings is presented here, along with a case study from the chemical industry. A DOE study is used to collect data, and two ML models are applied to predict responses which performance show an advantage over the traditional modeling approach. Emphasis is placed on causal investigation and quantification of prediction uncertainty, as these are crucial for an assessment of the goodness and robustness of the models developed. Within the scope of the case study, the models learned can be implemented in a semi-automatic system that can assist practitioners who are inexperienced in data analysis in the process of new product development. 相似文献

This article follows on from our previous one about the armed conflict in Colombia and its relationship with disability. We seek here to explore the ways in which people with disabilities are starting to be involved in the peace process with the Revolutionary Armed Forces of Colombia – People’s Army (FARC-EP), and the avenues there are for representative organizations of disabled people to have a louder voice in Colombia. Currently, while legal and human rights approaches are important, people with disabilities in Colombia do not generally have the resources to fight for their own rights. However, there could be opportunities in the negotiations currently with the National Liberation Army (ELN) to include a specific focus on the rights of people with disabilities. 相似文献
