This article extends psychoanalytic theories of “holding” and “psychic skin” to examine the containing function of romantic love. It argues that love can function to organize our inner world, helping our lives feel coherent and protecting us from what feels externally threatening, whether projected elements of our own psyches, the risk of breakdown, or true dangers existing in reality. The containing function of love is looked at through instances where it fails, and loss of love precipitates psychic disintegration. Through clinical examples and studies of two novels, Elena Ferrante’s Days of Abandonment and Doris Lessing’s The Golden Notebook, this article proposes that living and loving without illusions of certainty opens possibilities for integrated love with whole and imperfect objects. 相似文献

The objective of this article is to find out why immigrants intend to stay in or leave their initial destination. The insight into such factors could help develop policy measures to deal with potential out‐migration, especially from the regions that view international migration as a solution to their demographic and economic difficulties. The study uses multinomial logistic regression to estimate the strength of association between migrants' intention to move and immigration category, human capital, economic and social factors. The data come from the Longitudinal Survey of Immigrants to Australia. The findings show that different groups of migrants have different propensities to move or stay in their initial destination. Employer‐sponsored migrants are even less likely to intend to relocate than family class. Highly educated and skilled migrants tend to be more likely to express the intention to move or have doubts. Satisfactory employment has a positive impact on retention. 相似文献

This article examines some difficulties associated with the Haynes–Stone model and attempts to clarify how the model can be justified as representing the hypothesis that “quantity is demand determined and price is supply determined.” It also argues that the applications of such a model as was done by Haynes and Stone might not have resolved the controversies related to the Phillips curve and the supply function of exports (or imports). 相似文献

Chemical Health Effects Assessment Methodology (CHEM) is a new procedure for assessing hazardous properties of airborne toxic contaminants. CHEM evaluates substances for four major health effect categories: carcinogenicity, mutagenicity, reproductive/developmental toxicity, and toxic effects other than the first three. Three elements are considered in the assessment: weight of evidence, potency, and severity of effect. This approach produces a profile of toxic properties of chemicals which preserves their unique multidimensional character and highlights data gaps. 相似文献

Cross-cultural researches on the Ryff’s Psychological Well-being (PWB) Scales are currently not available. The aim of the paper was to investigate the measurement invariance of the 18-item version of the PWB Scales across 1,114 high school and undergraduate Italian and Belarusian students. After identifying the six correlated first-order factors and one second-order factor model of the Ryff’s PWB Scales, as baseline model for each sample, multi-groups confirmatory factor analyses were subsequently performed. All analyses were performed using the Robust Diagonally Weighted Least Squares estimation procedures, entering a polychoric correlation matrix. Multi-groups analyses showed that factor structure of the preferred model did not change across the Italian and Belarusian samples. Although the obtained results provided a preliminary support for cross-cultural structural invariance of the PWB Scales, further investigations are required to ensure its generalizability and applicability. Limitations and suggestions for future researches as well as psychosocial applications for educational context were discussed. 相似文献

Nonparametric estimation of the cumulative intensities in an interval censored competing risks model 总被引:1,自引:0,他引:1
The nonparametric maximum likelihood estimation (NPMLE) of the distribution function from the interval censored (IC) data has been extensively studied in the extant literature. The NPMLE was also developed for the subdistribution functions in an IC competing risks model and in an illness-death model under various interval-censoring scenarios. But the important problem of estimation of the cumulative intensities (CIs) in the interval-censored models has not been considered previously. We develop the NPMLE of the CI in a simple alive/dead model and of the CIs in a competing risks model. Assuming that data are generated by a discrete and finite mixed case interval censoring mechanism we provide a discussion and the simulation study of the asymptotic properties of the NPMLEs of the CIs. In particular we show that they are asymptotically unbiased; in contrast the ad hoc estimators presented in extant literature are substantially biased. We illustrate our methods with the data from a prospective cohort study on the longevity of dental veneers. 相似文献

Objectives: To assess sex hormones, leptin and insulin-resistance in men with prostate cancer (PCa) and benign prostatic hyperplasia (BPH) and to study associations between androgens and histologic score of prostate tissue in PCa.Subjects and methods: Two hundred ten men older than 45 years selected from 2906 participants of a population screening for PCa were studied: 70 with PCa, 70 with BPH and 70 controls (CG), matched by body mass index and age. Insulin, IGF-1, PSA, leptin, total, free (fT) and bioavailable testosterone (bT) and estradiol were measured. Each group was subdivided into two subgroups considering the presence of metabolic syndrome (MS); androgens and leptin levels were analyzed in the subgroups.Results: Prostate cancer and BPH patients presented higher total, fT and bT levels than CG. IGF-1, insulin and HOMA index were higher in BPH than in the other two groups. PCa presented higher leptin [median (range) 6.5 (1.3–28.0) versus 4.8 (1.1–12.3) ng/ml; p?0.01] and estradiol [median (range) 37.0 (20–90) versus 29.0 (20–118) pg/ml; p?=?0.025] levels than CG. After dividing men considering the presence of MS, leptin was higher and total testosterone was lower in MS patients in all the groups.Conclusions: It was observed a coexistence of an altered hormone profile with increased sex hormones and leptin in PCa patients, in accordance with the new perspective of PCa pathogenesis. 相似文献

Population health and its determinants are one of the major challenges to social and economic policy. The aim of this study was to investigate the relationship between occupational activity and biological condition in adult working Polish men. The participants of the study were 300 men (30–65 years), healthy inhabitants of the city of Wroclaw, Poland. Seventeen measures of biological condition were examined. The subjects were divided into three different occupational groups: professionals, soldiers and skilled workers. A comparison of biological age profiles of three occupational groups showed that in the majority of characteristics, professionals had the youngest biological age, whereas skilled workers had the highest biological age. The results for soldiers were not as unambiguous, but biological parameters were generally closer to those for professionals. Inborn biological predispositions and long-term impact of the working environment can influence on the biological condition of various professional groups. Knowledge of the determinants of biological condition might result in efficient use of predisposition to work or may be of help in extending their time of work ability. 相似文献
