The work of the goldsmiths consists in the manufacture of jewelry. The piece, be it an earring, bracelet or necklace, is hand-assembled. This task requires precision, skill, kindness and patience. In this work, we make use of tools such as cuticle clippers and rounded tip, beads or precious stones and also pieces of metal. This type of activity requires a biomechanical stress of hands and wrists. In order to quantify the biomechanical stress, we performed a case study to measure the movements performed by an assembly of pieces of jewelry. As method for research, filming was done during assembly of parts to a paste, using a Nikon digital camera, for 1 (one) hour. The film was edited by Kinovea software, and the task was divided into cycles, each cycle corresponds to a complete object. In one cycle, there are four two movements of supination and pronation movements of the forearm. The cycle lasts approximately sixteen seconds, totaling 1800 cycles in eight hours. Despite the effort required of the wrists, the activity shows no complaints from the employees, but this fact does not mischaracterizes the ability of employees to acquire repetitive strain injuries and work-related musculoskeletal disorders.  相似文献

We evaluated the effects of long-term testosterone replacement therapy (TRT) on the bone mineral density (BMD) in obese patients with metabolic syndrome (MS) and late-onset hypogonadism (LOH). Sixty men (mean age 57 ± 10) with low serum testosterone (T < 320 ng/dL) and MS regardless the presence of osteoporosis were enrolled. Forty men received intramuscular T-undecanoate (TU) four times/year for 36 months and 20 age-matched hypogonadal men with MS in whom T treatment was contraindicated were used as controls. Hormonal, biochemical markers, vertebral and femoral BMD by dual-energy x-ray absorptiometry were measured. At baseline, overall patients had mild osteopenia (lumbar BMD= 0.891 ± 0.097 g/cm(2); femoral BMD= 0.847 ± 0.117 g/cm(2)). TU induced a significant improvement of bone mass after 36 months (lumbar BMD=1.053 ± 0.145 g/cm(2); p < 0.002; femoral BMD=0.989 ± 0.109; p < 0.003 g/cm(2)) with a 5%/year increase and a significant reduction in hs-CRP without changes in body mass index. A direct relationship between serum T and BMD increments at the lumbar (r(2)?= 0.66, p < 0.0001) and femoral (r(2)?=0.52, p < 0.0001) sites was demonstrated. Study adherence was 50% without serious side effects. Long-term TRT in middle-aged men with LOH and MS determines a significant increase in both vertebral and femoral BMD related to increased serum T levels, probably independently from estradiol modifications.  相似文献

Inspired by the relational framework (Bassi, in: Franz, Hochgerner, Howaldt (eds) Challenge social innovation, Springer, Berlin, pp 325–350, 2012; Donati in Ital J Sociol Educ 5(1):19–35, 2013) and designed to integrate psychological and sociological aspects, a measure of social added value (SAV) was developed and validated. A study was conducted in the South of Italy on a sample of non-profit and voluntary organization members (N?=?394) to examine the statistical validity and psychometric properties of the SAV scale. Confirmatory factor analyses showed that a third-order factor model, saturated by two second-order variables (internal and external relational goods) and eight first-order variables (sense of organizational community, quality of internal relations, influence, social responsibility towards members of the organization, users and stakeholders, organizational identification, and quality of external relations) obtained good satisfactory fit indexes. Additional analyses revealed that shared member values were positively associated with SAV and that there were differences among organizations according to their legal forms and the organizational roles available. Theoretical, methodological, and practical implications of the findings are discussed.  相似文献

Patterns of consent: evidence from a general household survey   总被引:1,自引:0,他引:1  
Summary.  We analyse patterns of consent and consent bias in the context of a large general household survey, the 'Improving survey measurement of income and employment' survey, also addressing issues that arise when there are multiple consent questions. A multivariate probit regression model for four binary outcomes with two incidental truncations is used. We show that there are biases in consent to data linkage with benefit and tax credit administrative records that are held by the Department for Work and Pensions, and with wage and employment data held by employers. There are also biases in respondents' willingness and ability to supply their national insurance number. The biases differ according to the question that is considered. We also show that modelling questions on consent independently rather than jointly may lead to misleading inferences about consent bias. A positive correlation between unobservable individual factors affecting consent to Department for Work and Pensions record linkage and consent to employer record linkage is suggestive of a latent individual consent propensity.  相似文献

When the target variable exhibits a semicontinuous behavior (a point mass in a single value and a continuous distribution elsewhere), parametric “two-part models” have been extensively used and investigated. The applications have mainly been related to non negative variables with a point mass in zero (zero-inflated data). In this article, a semiparametric Bayesian two-part model for dealing with such variables is proposed. The model allows a semiparametric expression for the two parts of the model by using Dirichlet processes. A motivating example, based on grape wine production in Tuscany (an Italian region), is used to show the capabilities of the model. Finally, two simulation experiments evaluate the model. Results show a satisfactory performance of the suggested approach for modeling and predicting semicontinuous data when parametric assumptions are not reasonable.  相似文献

In the last decade, the European Union (EU) approach to genderequality has broadened to new concepts, such as gender mainstreaming,and new issues, such as "family policies", "domestic violence",and "gender inequality in politics". However, the frame analysisof policy documents in these new areas shows, first, that eachissue has developed its own particular features, and, secondly,that the broadening of the EU-political discourse on genderequality has not led to a deeper framing of the issues in termsof gender equality. The lack of EU competence in these areas,the status of the policy documents, and differences in the actorshaving a voice and being referred to in the documents are proposedas possible explanations for its framing.  相似文献

Background

The prevalence of fear of childbirth in pregnant women is described to be about 20–25%, while 6–10% of expectant mothers report a severe fear that impairs their daily activities as well as their ability to cope with labour and childbirth. Research on fear of childbirth risk factors has produced heterogeneous results while being mostly done with expectant mothers from northern Europe, northern America, and Australia.

Aims

The present research investigates whether fear of childbirth can be predicted by socio-demographic variables, distressing experiences before pregnancy, medical-obstetric factors and psychological variables with a sample of 426 Italian primiparous pregnant women.

Methods

Subjects, recruited between the 34th and 36th week of pregnancy, completed a questionnaire packet that included the Wijma Delivery Expectancy Questionnaire, the Edinburgh Postnatal Depression Scale, the State-Trait Anxiety Inventory, the Dyadic Adjustment Scale, the Multidimensional Scale of Perceived Social Support, as well as demographic and anamnestic information. Fear of childbirth was treated as both a continuous and a dichotomous variable, in order to differentiate expectant mothers as with a severe fear of childbirth.

Findings

Results demonstrate that anxiety as well as couple adjustment predicted fear of childbirth when treated as a continuous variable, while clinical depression predicted severe fear of childbirth.

Conclusions

Findings support the key role of psychological variables in predicting fear of childbirth. Results suggest the importance of differentiating low levels of fear from intense levels of fear in order to promote adequate support interventions.  相似文献

The study offers an alternative explanation for the role of trust in economic exchange, answering the critical research questions of how and under what conditions suppliers’ trust affects manufacturers’ innovation capability. The study adopts a transaction value approach suggesting combining strategy and organisational economic literature to fully investigate the processes through which joint value is generated and developed by interacting partners. Using survey data from a sample of 235 supplier–manufacturer relationships, we find broad support for the model hypotheses. The results confirm the mediating role of asset specificity and knowledge sharing as procedural dimensions in the relation between suppliers’ trust and manufacturers’ innovation capability. However, the direct path between trust and innovation capability was not confirmed. The study provides theoretical and practical implications for firms seeking to translate inter-firm trust into innovation-based competitive advantage.  相似文献
