A grounded theory qualitative study was developed to explore how grandparents perceive their role as socializing agents. Forty‐two grandparents with grandchildren aged from 6 to 12 years old participated in this study. Data were collected through focus groups, which were conducted until reaching data saturation and analyzed using the constant comparative method. Four general conclusions emerged from the study: (i) grandparents recognized the importance of getting involved in the socialization of grandchildren as supporters of parents' socializing role, and the need to adapt to social changes; (ii) they emphasized traditional value that were perceived in decline, and combination of warmth and involvement were considered the best way to help grandchildren internalize values; (iii) interaction with grandchildren helped grandparents to feel active and useful, increased their life purpose and gave them a second chance to enjoy what they could not with their own children; and (iv) grandparents also accused burden and role ambiguity. These results show the importance of developing family policies that recognize grandparents' socializing role. Also, interventions that promote strategies that enable grandparents to perform their role more successfully and to cope with possible family conflicts should be developed. 相似文献

This paper explores the relationship between governance and social innovation in the area of organizations. In order to understand that relationship, we offer a model that links the absorptive capacity of knowledge [Cohen and Levinthal 1990. “Absorptive Capacity: A new Perspective on Learning and Innovation.” Administrative Science Quarterly 35 (1): 128–152] with open innovation [Chesbrough and Di Minin 2014. “Open Social Innovation.” In New Frontiers in Open Innovation, edited by H. Chesbrough, W. Vanhaverbeke, and J. West, 169–187. Oxford: Oxford University Press]. On the basis of the pilot study Regional Social Innovation Index carried out in the Basque Country (Spain), we empirically explore three types of governance (social, inter-organizational, and sustainable) in social innovation projects propelled by four types of key agents at a regional level: profit and non-profit organizations, universities, and technology centers. The proposed governance Index in Social Innovation contributes to discussions about governance and social innovation at a micro level and, and to the debate about the production of indicators in social innovation. 相似文献

What can local public sociology look like, and what does it accomplish? This essay tracks the origins, makings and impacts of the book Invisible in Austin to evaluate its model of public sociology: as a collective enterprise with a local aim. Invisible in Austin: Life and Labor in an American City, the culmination of a three-year collaborative qualitative research project between a professor and twelve graduate students, depicts social suffering as lived for 11 individuals in Austin, Texas—a booming, highly segregated city with one of the country’s highest levels of income inequality. In its design, production, and effects, it envisions public sociology in a two-fold sense—in its joint, horizontal making, and in its intent to intervene in the local public sphere to make visible the daily lived experience of social marginality for those whose labor allows Austin to survive and thrive as a hip, creative technopolis—house cleaners, office machine repairers, cab drivers, restaurant cooks and dish washers, exotic dancers, musicians, and roofers, among them. Reflecting on the origins of the book, its joint assembling, and its outcomes thus far, we take stock of the lessons learned. In so doing, we provide a rubric for evaluating the wide spectrum of possible impacts of a public sociological intervention: through direct and indirect audience engagements, on the project’s subjects, and on local public policy. This reflection concludes with three suggestions: to approach public sociology as collective enterprise, to take narrative seriously, and to seek wide exposure. 相似文献

Research on the risk of motor vehicle injuries and their relationship with the amount of travel has been only partially analyzed. The few individual exposure assessments are related to very specific subsets of the driving and traveling populations. This study analyzes the relationship between kilometers traveled and hospitalization due to motor vehicle injuries. Twelve thousand three hundred and sixty nine Spanish university graduates from the Seguimiento Universidad de Navarra multipurpose cohort study were evaluated. They had not been hospitalized due to motor vehicle injuries at baseline and were followed up to eight years. Biannual questionnaires allowed for self‐reporting of kilometers traveled in motor vehicles, together with incidence of hospitalization. Covariates in the Cox regression models included age and gender and baseline use of safety belt while driving, driving a vehicle with driver‐side airbag, driving a motorcycle, and drinking and driving. There were 49,766 participant‐years with an average yearly travel of 7,828 km per person‐year. Thirty‐six subjects reported a first hospitalization event during this time. The adjusted hazard ratio per additional kilometer traveled was 1.00005 (95% confidence interval 1.000013 to 1.000086). Even the smallest of reductions in the amount of kilometers traveled (from an average of 3,250 km per year to 1,000) has a statistically significant protective effect on the likelihood of sustaining hospitalization due to motor vehicle injury (aHR 0.9, 95% CI 0.78 to 0.98). In light of current policies aimed to reduce motorized traffic due to environmental concerns, it may be appropriate to consider the additional health benefit related to reductions in injuries. 相似文献

Combining Food Frequency and Survey Data to Quantify Long-Term Dietary Exposure: A Methyl Mercury Case Study 总被引:2,自引:0,他引:2
Twenty-four-hour recall data from the Continuing Survey of Food Intake by Individuals (CSFII) are frequently used to estimate dietary exposure for risk assessment. Food frequency questionnaires are traditional instruments of epidemiological research; however, their application in dietary exposure and risk assessment has been limited. This article presents a probabilistic method of bridging the National Health and Nutrition Examination Survey (NHANES) food frequency and the CSFII data to estimate longitudinal (usual) intake, using a case study of seafood mercury exposures for two population subgroups (females 16 to 49 years and children 1 to 5 years). Two hundred forty-nine CSFII food codes were mapped into 28 NHANES fish/shellfish categories. FDA and state/local seafood mercury data were used. A uniform distribution with minimum and maximum blood-diet ratios of 0.66 to 1.07 was assumed. A probabilistic assessment was conducted to estimate distributions of individual 30-day average daily fish/shellfish intakes, methyl mercury exposure, and blood levels. The upper percentile estimates of fish and shellfish intakes based on the 30-day daily averages were lower than those based on two- and three-day daily averages. These results support previous findings that distributions of "usual" intakes based on a small number of consumption days provide overestimates in the upper percentiles. About 10% of the females (16 to 49 years) and children (1 to 5 years) may be exposed to mercury levels above the EPA's RfD. The predicted 75th and 90th percentile blood mercury levels for the females in the 16-to-49-year group were similar to those reported by NHANES. The predicted 90th percentile blood mercury levels for children in the 1-to-5-year subgroup was similar to NHANES and the 75th percentile estimates were slightly above the NHANES. 相似文献

Structure and composition of woody plants in urban forest remnants with different adjacent land-use and slope aspect 总被引:1,自引:0,他引:1
The plant community in the karst forest is influenced by mesoclimatic conditions, such as temperature and humidity and these
conditions are in turn influenced by topographic features. Urban areas adjacent to karstic forest remnants also have the potential
to influence mesoclimatic variables and may serve as a source of exotic species. We described the temperature and relative
humidity of karstic forest remnants at slopes with combinations of either southeast (SE) or northwest (NW) aspect, and adjacent
to either urban (URB) or secondary forest (SF). We also compared forest structure and composition on these slopes to understand
the interaction between forest aspect and adjacent land use on the plant community. URB-SE slopes had highest temperature
and lowest humidity among all adjacent land use-aspect combinations. Understory species in SE slopes had similar richness
and diversity independently of adjacent land use, however within NW aspect, slopes adjacent to urban areas showed higher values
than slopes adjacent secondary forest. Canopy trees species in slopes adjacent to secondary forest were more diverse and rich
in SE than in NW, although no differences between aspects were detected within URB-adjacent slopes. Understory species composition
was different among the four land use-aspect combinations. However, composition of canopy trees species was different only
between aspect types. Most exotic species in the sites were associated with previous agricultural practices and not with current
land use. Our results show a temporal and spatial influence of anthropogenic systems on the plant community in karstic forest
remnants at a suburban area of Puerto Rico. 相似文献

This article studies robustification strategies for the linear model in the presence of outliers. The advantages of an internal analysis of the robustness of least squares for a given sample are pointed out. The application of this methodology is illustrated by building an explicit model of the determinants of rental housing values in the Madrid Metropolitan Area. 相似文献

This paper provides an analysis of the Minimal Overlap Rule, a solution for bankruptcy problems introduced by O’Neill (1982). We point out that this rule can be understood as a composition
of Ibn Ezra’s proposal and the recommendation given by the Constrained Equal Loss Rule. Following an interpretation of bankruptcy problems in terms of TU games, we show that the Minimal Overlap Value is the unique solution for bankruptcy games which satisfies Anonymity and Core Transition Responsiveness. 相似文献
