Hegemonic Masculinities and Heteronormativities in Contemporary Books on Fathering and Raising Boys

Books published on fathering and raising boys are becoming increasingly popular. These books claim simply to describe boys and fathers. However we suggest that they make only specific identities available. We make this suggestion on the basis of a critical analysis of six books published since an initial study by Riggs (2008). In this article we extend Riggs’s analysis by identifying how the books analyzed draw upon hegemonic masculine ideals in constructing boys’ and fathers’ identities. The analysis also suggests that biological essentialism is used to justify the identities constructed. Five specific implications are drawn from the findings, focusing on understandings of males as well as females, the uptake of dominant modes of talking about males, and the ramifications of biological essentialism. The findings emphasize the need to pay ongoing attention to popular parenting books since, rather than offering improved strategies for raising boys, these books present assertions of what boys and fathers should be

Maternal exposure to dibutyl phthalate (Dbp) or diethylstilbestrol (des) leads to long-term changes in hypothalamic gene expression and sexual behavior

Xenobiotic exposure during pregnancy and lactation has been linked to perinatal changes in male reproductive outcomes and other endocrine parameters. This pilot study wished to assess whether brief maternal exposure of rats to xenobiotics dibutyl phthalate (DBP) or diethylstilbestrol (DES) might also cause long-term changes in hypothalamic gene expression or in reproductive behavior of the resulting offspring. Time-mated female Sprague Dawley rats were given either DBP (500 mg/kg body weight, every second day from GD14.5 to PND6), DES (125 µg/kg body weight at GD14.5 and GD16.5 only), or vehicle (n = 8–12 per group) and mild endocrine disruption was confirmed by monitoring postnatal anogenital distance. Hypothalamic RNA from male and female offspring at PND10, PND24 and PND90 was analyzed by qRT-PCR for expression of aromatase, oxytocin, vasopressin, ER-alpha, ER-beta, kisspeptin, and GnRH genes. Reproductive behavior was monitored in male and female offspring from PND60 to PND90. Particularly, DES treatment led to significant changes in hypothalamic gene expression, which for the oxytocin gene was still evident at PND90, as well as in sexual behavior. In conclusion, maternal xenobiotic exposure may not only alter endocrine systems in offspring but, by impacting on brain development at a critical time, can have long-term effects on male or female sexual behavior

Knife seizure imagery project report

The urgency to reduce knife crime and knife carrying has remained a primary issue for policy makers and police authorities across Scotland. Young people, particularly those living in the most deprived areas, have been identified as those most at risk of being exposed to higher levels of knife crime and assault related sharp-force injuries. Sharing images of recovered/seized knives in police campaigns and across media outlets (e.g., newspapers, online articles and social media) has been one strategy used to help deter knife carrying. The intention behind the use of knife seizure images is to warn the public of the dangers of knives and to show the success of police efforts in seizing weapons off the streets. However, little empirical research has been conducted to explore whether the use of knife seizure images is an effective deterrent. The aim of this study was to explore the views of young people living in areas of high and low rates of knife crime areas across Glasgow, to gain their perspectives concerning the use of knife seizure images as a crime-deterrent. Between January 2021 and April 2021, a group of 20 young people were invited to take part in online interviews. They were spilt into two equal groups, those living in higher or in lower areas of knife crime around Glasgow (determined by the Scottish Indicator of Multiple Deprivation). A collection of knife images obtained from published articles by the UK news media and from stock images produced by No Knifes Better Lives were shown to the participants

TU Tau B: The Peculiar 'Eclipse' of a possible proto-Barium Giant

TU Tau (= HD 38218 = HIP 27135) is a binary system consisting of a C-N carbon star primary and an A-type secondary. We report on new photometry and spectroscopy which tracked the recent disappearance of the A-star secondary. The dimming of the A-star was gradual and irregular, with one or more brief brightenings, implying the presence of nonhomogeneities in the carbon star outflow. We also present evidence that the A-star is actively accreting s-process enriched material from the carbon star and suggest that it will therefore eventually evolve into a Barium giant. This is an important system as well because the A-type star can serve as a probe of the outer atmosphere of the carbon star.Comment: 9 pages, 9 figures, 4 tables, a number of amateur observatories made significant contributions to this research.

Are images of seized knives an effective crime deterrent? A comparative thematic analysis of young people’s views within the Scottish context

The urgency to reduce knife carrying has been recognised by police services within Scotland and has been addressed by initiatives such as the sharing of knife seizure images on media outlets. This study sought to explore young peoples’ views on the use of knife seizure images as a deterrent to carrying knives by using comparative individual interviews (N = 20) with photo elicitation. Three themes were discovered: (1) negative reactions towards images of seized knives, (2) images of knives may encourage rather than deter knife carrying, and (3) reinforcement of existing beliefs, stereotypes and stigma. These findings highlight the limitations of using knife seizure images as a deterrent and the importance of involving young people in developing preventative and non-discriminatory approaches to tackling knife crime.</p

A Genotype-First Approach for the Molecular and Clinical Characterization of Uncommon De Novo Microdeletion of 20q13.33

Background: Subtelomeric deletions of the long arm of chromosome 20 are rare, with only 11 described in the literature. Clinical features of individuals with these microdeletions include severe limb malformations, skeletal abnormalities, growth retardation, developmental and speech delay, mental retardation, seizures and mild, non-specific dysmorphic features. Methodology/Principal Findings: We characterized microdeletions at 20q13.33 in six individuals referred for genetic evaluation of developmental delay, mental retardation, and/or congenital anomalies. A comparison to previously reported cases of 20q13.33 microdeletion shows phenotypic overlap, with clinical features that include mental retardation, developmental delay, speech and language deficits, seizures, and behavior problems such as autistic spectrum disorder. There does not appear to be a clinically recognizable constellation of dysmorphic features among individuals with subtelomeric 20q microdeletions. Conclusions/Significance: Based on genotype-phenotype correlation among individuals in this and previous studies, we discuss several possible candidate genes for specific clinical features, including ARFGAP1, CHRNA4 and KCNQ2 and neurodevelopmental deficits. Deletion of this region may play an important role in cognitive development

Integrating inland and coastal water quality data for actionable knowledge

Water quality measures for inland and coastal waters are available as discrete samples from professional and volunteer water quality monitoring programs and higher-frequency, near-continuous data from automated in situ sensors. Water quality parameters also are estimated from model outputs and remote sensing. The integration of these data, via data assimilation, can result in a more holistic characterization of these highly dynamic ecosystems, and consequently improve water resource management. It is becoming common to see combinations of these data applied to answer relevant scientific questions. Yet, methods for scaling water quality data across regions and beyond, to provide actionable knowledge for stakeholders, have emerged only recently, particularly with the availability of satellite data now providing global coverage at high spatial resolution. In this paper, data sources and existing data integration frameworks are reviewed to give an overview of the present status and identify the gaps in existing frameworks. We propose an integration framework to provide information to user communities through the the Group on Earth Observations (GEO) AquaWatch Initiative. This aims to develop and build the global capacity and utility of water quality data, products, and information to support equitable and inclusive access for water resource management, policy and decision making.Additional co-authors: Anders Knudby, Camille Minaudo, Nima Pahlevan, Ils Reusen, Kevin C.
