Reciprocal Prospective Associations Between Depressive Symptoms and Perceived Relationship With Parents in Early Adolescence

Objective: Adolescent depressive symptoms are associated with difficult family relationships. Family systems and interpersonal theories of depression suggest that this association could reflect a circular process in which symptoms and family functioning affect each other over time. Few longitudinal studies have tested this hypothesis, and the results of these studies have been equivocal. In this study, we examine reciprocal prospective associations in early adolescence between depressive symptoms and 2 important aspects of parent–child relationships: communication and conflict. Methods: Participants were 3862 students who annually filled out self-reports. Path analysis was used to examine prospective associations between depressive symptoms and perceived communication and conflict with parents from the age of 12 to 13 and 14 to 15 years. Independence of these associations was assessed by controlling for family context (parental separation and family socioeconomic status) and adolescent behaviour problems (delinquent behaviours and substance use). Sex differences were evaluated with multiple group analysis. Results: Reciprocal prospective associations were found between depressive symptoms and perceived conflict with parents, but not between depressive symptoms and communication with parents. Depressive symptoms were found to predict poorer communication with parents over time, but communication was not predictive of lower depressive symptoms in subsequent years. All paths were sex-invariant and independent from family context and behaviour problems. Conclusion: This study highlights the importance of considering the potential impact of adolescent symptomatology on parent–child relationships and suggests that reciprocity may characterize the association between depressive symptoms and negative aspects of parent–child relationships. The role of adolescent perceptions in the interplay between depressive symptoms and family relationships remains to be clarified.

Masculinity-femininity as a national characteristic and its relationship with national agoraphobic fear levels: Fodor's sex role hypothesis revitalized

Hofstede's dimension of national culture termed Masculinity-Femininity [Hofstede (1991). Cultures and organizations: software of the mind. London: McGraw-Hill] is proposed to be of relevance for understanding national-level differences in self-assessed agoraphobic fears. This prediction is based on the classical work of Fodor [Fodor (1974). In: V. Franks & V. Burtle (Eds.), Women in therapy: new psychotherapies for a changing society. New York: Brunner/Mazel]. A unique data set comprising 11 countries (total N = 5491 students) provided the opportunity of scrutinizing this issue. It was hypothesized and found that national Masculinity (the degree to which cultures delineate sex roles, with masculine or tough societies making clearer differentiations between the sexes than feminine or modest societies do) would correlate positively with national agoraphobic fear levels (as assessed with the Fear Survey Schedule-III). Following the correction for sex and age differences across national samples, a significant and large effect-sized national-level (ecological) r = +0.67 (P = 0.01) was found. A highly feminine society such as Sweden had the lowest, whereas the champion among the masculine societies, Japan, had the highest national Agoraphobic fear score. (C) 2003 Elsevier Science Ltd.

Tumor progression in hepatocellular carcinoma: Relationship with tumor stroma and parenchymal disease

Background: Encapsulation in hepatocellular carcinoma is associated with decreased invasiveness and improved survival in several series. Although active fibrogenesis by myofibroblasts has been demonstrated in the capsule, it is unclear if the capsule results from a general increase in peritumoral fibrosis, or an inherently less invasive tumor phenotype. The relationship between collagen deposition within tumor stroma, presence of cirrhosis and invasiveness also needs clarification. Methods: We performed immunohistochemistry for collagens I, III, IV and VI on sections of encapsulated and non-encapsulated hepatocellular carcinoma, arising in cirrhotic and non-cirrhotic livers. Staining was graded semi-quantitatively in tumor stromal elements and adjacent parenchymal sinusoids. The relationship of this staining with encapsulation, cirrhosis, and vascular invasion was analyzed. Results: Formation of a discrete capsular layer was associated with reduced vascular invasion, but not with a pervasive increase in peritumoral fibrosis. Increased collagen I content of tumor stroma and adjacent parenchymal sinusoids was associated with non-encapsulated tumors and vascular invasion. The presence of cirrhosis had little effect on capsule composition. Conclusions: Encapsulation of hepatocellular carcinoma reflects reduced invasiveness, rather than increased peritumoral collagen synthesis, which may instead enhance invasion. Increased intratumoral collagen I protein is also associated with increased tumor invasiveness. Pre-existing cirrhosis has little effect on tumor progression, possibly because the characteristics of cirrhosis are overwhelmed by tumor-induced changes in the adjacent parenchyma.(C) 2003 Blackwell Publishing Asia Pty Ltd.

Dizziness and unsteadiness following whiplash injury: Characteristic features and relationship with cervical joint position error

Dizziness and/or unsteadiness are common symptoms of chronic whiplash-associated disorders. This study aimed to report the characteristics of these symptoms and determine whether there was any relationship to cervical joint position error. Joint position error, the accuracy to return to the natural head posture following extension and rotation, was measured in 102 subjects with persistent whiplash-associated disorder and 44 control subjects. Whiplash subjects completed a neck pain index and answered questions about the characteristics of dizziness. The results indicated that subjects with whiplash-associated disorders had significantly greater joint position errors than control subjects. Within the whiplash group, those with dizziness had greater joint position errors than those without dizziness following rotation (rotation (R) 4.5degrees (0.3) vs 2.9degrees (0.4); rotation (L) 3.9degrees (0.3) vs 2.8degrees (0.4) respectively) and a higher neck pain index (55.3% (1.4) vs 43.1% (1.8)). Characteristics of the dizziness were consistent for those reported for a cervical cause but no characteristics could predict the magnitude of joint position error. Cervical mechanoreceptor dysfunction is a likely cause of dizziness in whiplash-associated disorder.

Australia's relationship with the United States: The case for greater independence

A number of recent events-especially attempts to negotiate a bilateral trade agreement and Australia's participation in the conflicts in Afghanistan and Iraq(1)-have thrown Australia's relationship with the United States into sharp relief. While this relationship has historically enjoyed strong bilateral endorsement, such uncritical support is beginning to unravel. At the very least, the relationship is being subjected to a renewed, more critical scrutiny. This paper argues that a dispassionate analysis of the relationship is appropriate and overdue. Not only are the benefits that accrue to 'Australia' from the relationship debateable, even when judged within the limited calculus of the 'national interest', but Australia's uncritical support for US foreign policy is also helping to entrench potentially damaging aspects of American foreign policy and somewhat ironically-undermining the legitimacy of its pre-eminent 'hegemonic' position.

Ross River virus disease clusters and spatial relationship with mosquito biting exposure in Redland Shire, southern Queensland, Australia

The spatial heterogeneity in the risk of Ross River virus (family Togaviridae, genus Alphavirus, RRV) disease, the most common mosquito-borne disease in Australia, was examined in Redland Shire in southern Queensland, Australia. Disease cases, complaints from residents of intense mosquito biting exposure, and human population data were mapped using a geographic information system. Surface maps of RRV disease age-sex standardized morbidity ratios and mosquito biting complaint morbidity ratios were created. To determine whether there was significant spatial variation in disease and complaint patterns, a spatial scan analysis method was used to test whether the number of cases and complaints was distributed according to underlying population at risk. Several noncontiguous areas in proximity to productive saline water habitats of Aedes vigilax (Skuse), a recognized vector of RRV, had higher than expected numbers of RRV disease cases and complaints. Disease rates in human populations in areas which had high numbers of adult Ae. vigilax in carbon dioxide- and octenol-baited light traps were up to 2.9 times those in areas that rarely had high numbers of mosquitoes. It was estimated that targeted control of adult Ae. vigilax in these high-risk areas could potentially reduce the RRV disease incidence by an average of 13.6%. Spatial correlation was found between RRV disease risk and complaints from residents of mosquito biting. Based on historical patterns of RRV transmission throughout Redland Shire and estimated future human population growth in areas with higher than average RRV disease incidence, it was estimated that RRV incidence rates will increase by 8% between 2001 and 2021. The use of arbitrary administrative areas that ranged in size from 4.6 to 318.3 km2, has the potential to mask any small scale heterogeneity in disease patterns. With the availability of georeferenced data sets and high-resolution imagery, it is becoming more feasible to undertake spatial analyses at relatively small scales.

Aflatoxins and their relationship with sugars in peanut (Arachis hypogaea L.)

Aspergillus spp. produce aflatoxins in peanut, which poses a health risk to humans and animals, as well as affecting the marketability of peanuts. The current research found that more aflatoxin is produced under rain fed (RF) compared to irrigated (IRR) conditions, and was more predominant in juvenile (R3-5 stage) compared to older (R6-8 stage) pods. No aflatoxin was recorded in marketable pods of the Streeton cultivar in either of the growing conditions, whereas the cultivar NC-7 produced aflatoxin under RF conditions only. Sugars such as glucose, fructose and sucrose were positively correlated with total aflatoxins. It appears that Aspergillus utilises these simple carbohydrates as substrates in biosynthesis of aflatoxins.
