    The Asian Five Dragons: What’s the Relationship of Confucianism and Gender Inequality?

    Get PDF
    Confucianism is not only a historically important belief system, but it also continues to be rooted in many societies today, particularly in East and Southeast Asia. The growing influence of some of these Confucian-ingrained societies on the international stage justifies expanding the limited literature present on Confucianism and its societal implications. Using a conceptualization of heavily influenced Confucian societies previously set out by earlier research, this paper evaluates the validity of the common age-old assumption that Confucianism is correlated with greater gender inequality, as determined by the World 2016 dataset. Specifically, research suggests that the opposite correlation might just as equally be present in Confucian influenced societies today. This study tests the hypothesis that Confucian influence leads to lower gender inequality today compared to other influence systems. While the results cannot fully support the proposed hypothesis, the findings contribute considerable value to the limited Confucian literature by presenting strong statistical reasoning to doubt the common assumption of Confucianism being correlated with greater gender inequality

    Zero Entropy Interval Maps And MMLS-MMA Property

    Full text link
    We prove that the flow generated by any interval map with zero topological entropy is minimally mean-attractable (MMA) and minimally mean-L-stable (MMLS). One of the consequences is that any oscillating sequence is linearly disjoint with all flows generated by interval maps with zero topological entropy. In particular, the M\"obius function is orthogonal to all flows generated by interval maps with zero topological entropy (Sarnak's conjecture for interval maps). Another consequence is a non-trivial example of a flow having the discrete spectrum.Comment: 12 page

    Foodborne illness prevention in Debre Berhan, Ethiopia: Preliminary efforts to understand household agricultural practices

    Get PDF
    While strategies to mitigate risks for foodborne illness and childhood diarrhea via sanitation and behavioral interventions have been explored, there is a dearth of knowledge about household practices regarding food production and use, livestock, and other sources of risk for foodborne illness in urban and peri-urban areas. The objective of this research was to increase understanding of household agricultural practices in Debre Berhan, Ethiopia in order to design targeted behavioral interventions to improve food safety and decrease diarrheal disease. A convenience sample of 21 teachers and parents were recruited for a mixed-methods pilot survey. The survey covered topical areas such as methods for growing, washing, and cooking produce, specifically focusing on practices in home vegetable gardens. Participants were also asked about fertilizers and manures used, animals on the property, and irrigation water sources. Descriptive statistics were calculated, and data were analyzed with SAS 9.2. The majority ofparticipants (76.2%) reported growing some or all of their own food, and many used compost (62.5%) and manure (62.5%) as fertilizer. Uncomposted manure was used as fertilizer by half (50.0%) of respondents who reported the use of manure. Respondents most commonly reported raising chickens (23.8%), yet among those using manure, they most commonly reported using sheep or lamb manure as fertilizer (50%). Most (93.7%) respondents used municipal water to irrigate their crops, while none of the respondents reported using surface water to irrigate. Nearly all (95.2%) reported always washing their produce before eating it. Respondents most commonly requested education regardinghow to more effectively grow produce. This study suggests that children and adults in Debre Berhan may have a high risk of exposure to pathogens via contact with uncomposted manure and multiple species of animals. Findings identify an opportunity for increased education in the topical areas of urban agriculture and diarrheal disease prevention. In particular, education regarding the safe utilization of manure as fertilizer could be included in agricultural extension programs. Additional research is needed to understand the extent of exposure via common household sources to pathogens that cause diarrheal disease

    Offspring of parents with recurrent depression: which features of parent depression index risk for offspring psychopathology?

    Background: Parental depression is associated with an increased risk of psychiatric disorder in offspring, although outcomes vary. At present relatively little is known about how differences in episode timing, severity, and course of recurrentdepression relate to risk in children. The aim of this study was to consider the offspring of parents with recurrentdepression and examine whether a recent episode of parental depressionindexesrisk for offspringpsychopathology over and above these other parental depressionfeatures. <p/>Methods: Three hundred and thirty seven recurrently depressed parents and their offspring (aged 9–17) were interviewed as part of an ongoing study, the ‘Early Prediction of Adolescent Depression Study’. The Child and Adolescent Psychiatric Assessment was used to assess two child outcomes; presence of a DSM-IV psychiatric disorder and number of DSM-IV child-rated depression symptoms. <p/>Results: Children whose parents had experienced a recent episode of depression reported significantly more depression symptoms, and odds of child psychiatric disorder were doubled relative to children whose parents had not experienced a recent episode of depression. Past severity of parental depression was also significantly associated with child depression symptoms. <p/>Limitations: Statistical analyses preclude causal conclusions pertaining to parental depression influences on offspringpsychopathology; several features of parental depression were recalled retrospectively. <p/>Conclusions: This study suggests that particular features of parental depression, specifically past depression severity and presence of a recent episode, may be important indicators of risk for child psychiatric disorder and depressive symptoms
