The Role of Habit, Childhood Consumption, Familiarity and Attitudes Across Seafood Consumption Segments in Australia

Australian consumers hold very favorable attitudes toward seafood, with key drivers to consumption being taste, convenience, diet variety, and health benefits. Nevertheless, despite these positive attitudes, seafood consumption remains below many other countries. In this article, we investigate the influence of habit including regular childhood consumption, familiarity with seafood, and attitudes toward seafood on seafood consumption and consumption occasions. Habit and lack of familiarity with seafood were found to lead to lower levels of seafood consumption, whereas positive attitudes toward seafood were associated with more regular seafood consumption. People who consumed seafood on a regular basis as a child were more likely to be more familiar with seafood and be in the habit of consuming seafood in adulthood. Patterns of childhood consumption occasions were found to be associated with adult consumption occasions. Based on these findings, we discuss possible strategies and behavioral interventions for further investigation, which are grounded in habit theory and are aimed at changing seafood eating habits, increasing childhood consumption, and reducing the lack of familiarity with seafood

Invariants of Lie algebras extended over commutative algebras without unit

We establish results about the second cohomology with coefficients in the trivial module, symmetric invariant bilinear forms and derivations of a Lie algebra extended over a commutative associative algebra without unit. These results provide a simple unified approach to a number of questions treated earlier in completely separated ways: periodization of semisimple Lie algebras (Anna Larsson), derivation algebras, with prescribed semisimple part, of nilpotent Lie algebras (Benoist), and presentations of affine Kac-Moody algebras.Comment: v3: added a footnote on p.10 about a wrong derivation of the correct statemen

Rural Teachers’ Burnout, Well-Being, and COVID-19 Related Stress During the Pandemic

To date, researchers have not explored the impact of the COVID-19 pandemic on the well-being of rural teachers specifically. Rural schools already faced long-standing issues of lower salaries, professional isolation, teacher shortages, and technology challenges, suggesting rural teachers may have experienced even higher levels of distress due to the pandemic. Overall, however, teachers from one rural county school system in the southeastern United States reported moderate COVID-19 concerns, low distress, and moderate well-being. Results could reflect responses characteristic of rural resilience. Further study is needed to explore teachers’ unique coping strategies

General massive one-loop off-shell three-point functions

In this work we compute the most general massive one-loop off-shell three-point vertex in D-dimensions, where the masses, external momenta, and exponents of propagators are arbitrary. This follows our previous paper in which we have calculated several new hypergeometric series representations for massless and massive (with equal masses) scalar one-loop three-point functions, in the negative dimensional approach.Comment: 16 pages, 2 figures, 4 table

Warm Molecular Hydrogen Emission in Normal Edge-On Galaxies NGC 4565 and NGC 5907

We have observed warm molecular hydrogen in two nearby edge-on disk galaxies, NGC 4565 and NGC 5907, using the Spitzer high-resolution infrared spectrograph. The 0-0 S(0) 28.2 micron and 0-0 S(1) 17.0 micron pure rotational lines were detected out to 10 kpc from the center of each galaxy on both sides of the major axis, and in NGC 4565 the S(0) line was detected at r = 15 kpc on one side. This location lies beyond a steep drop in the radio continuum emission from cosmic rays in the disk. Despite indications that star formation activity decreases with radius, the H2 excitation temperature and the ratio of the H2 line and the far-IR luminosity surface densities, Sigma_L(H2}/Sigma_L(TIR}, change very little as a function of radius, even into the diffuse outer region of the disk of NGC 4565. This suggests that the source of excitation of the H2 operates over a large range of radii, and is broadly independent of the strength and relative location of UV emission from young stars. Although excitation in photodissociation regions is the most common explanation for the widespread H2 emission, cosmic ray heating or shocks cannot be ruled out. The inferred mass surface densities of warm molecular hydrogen in both edge-on galaxies differ substantially, being 4(-60) M_solar/pc^2 and 3(-50) M_solar/pc^2 at r = 10 kpc for NGC 4565 and NGC 5907, respectively. The higher values represent very unlikely point-source upper limits. The point source case is not supported by the observed emission distribution in the spectral slits. These mass surface densities cannot support the observed rotation velocities in excess of 200 km/s. Therefore, warm molecular hydrogen cannot account for dark matter in these disk galaxies, contrary to what was implied by a previous ISO study of the nearby edge-on galaxy NGC 891.Comment: Accepted for publication in the Astronomical Journal (20 pages, 17 figures, 7 tables

The significance of 'the visit' in an English category-B prison: Views from prisoners, prisoners' families and prison staff

A number of claims have been made regarding the importance of prisoners staying in touch with their family through prison visits, firstly from a humanitarian perspective of enabling family members to see each other, but also regarding the impact of maintaining family ties for successful rehabilitation, reintegration into society and reduced re-offending. This growing evidence base has resulted in increased support by the Prison Service for encouraging the family unit to remain intact during a prisoner’s incarceration. Despite its importance however, there has been a distinct lack of research examining the dynamics of families visiting relatives in prison. This paper explores perceptions of the same event – the visit – from the families’, prisoners’ and prison staffs' viewpoints in a category-B local prison in England. Qualitative data was collected with 30 prisoners’ families, 16 prisoners and 14 prison staff, as part of a broader evaluation of the visitors’ centre. The findings suggest that the three parties frame their perspective of visiting very differently. Prisoners’ families often see visits as an emotional minefield fraught with practical difficulties. Prisoners can view the visit as the highlight of their time in prison and often have many complaints about how visits are handled. Finally, prison staff see visits as potential security breaches and a major organisational operation. The paper addresses the current gap in our understanding of the prison visit and has implications for the Prison Service and wider social policy

Rehabilitating antisocial personalities: treatment through self-governance strategies

Offenders with antisocial personality disorder (ASPD) are widely assumed to reject psychotherapeutic intervention. Some commentators, therefore, argue that those with the disorder are better managed in the criminal justice system, where, following the introduction of indeterminate sentences, engagement with psychological treatment is coercively linked to the achievement of parole. By comparison, National Institute of Clinical Excellence guidelines on the management and treatment of ASPD recommend that those who are treatment seeking should be considered for admission to specialist psychiatric hospitals. The rationale is that prison-based interventions are underresourced, and the treatment of ASPD is underprioritised. The justification is that offenders with ASPD can be rehabilitated, if they are motivated. One problem, however, is that little is known about why offenders with ASPD seek treatment or what effect subsequent treatment has on their self-understanding. The aim of this paper is to address these unresolved issues. It draws on the findings of Economic and Social Research Council (ESRC) funded qualitative study examining the experiences of sentenced male offenders admitted to a specialist personality disorder ward within the medium secure estate and the medical practitioners who treat them. The data are analysed with reference to Michel Foucault’s work on governmentality and strategy in power relations. Two arguments are advanced: first, offenders with ASPD are motivated by legal coercive pressures to implement a variety of Foucauldian-type strategies to give the false impression of treatment progress. Second, and related, treatment does not result in changes in self-understanding in the resistive client with ASPD. This presupposes that, in respect of this group at least, Foucault was mistaken in his claim that resistive behaviours merely mask the effectiveness of treatment norms over time. Nevertheless, the paper concludes that specialist treatment in the hospital setting can effect changes in the resistive offender’s self-understanding, but not if the completion of treatment results, as is commonplace, in his prison readmission

Adverse drug reactions from psychotropic medicines in the paediatric population: analysis of reports to the Danish Medicines Agency over a decade

<p>Abstract</p> <p>Background</p> <p>The prescribing of psychotropic medicines for the paediatric population is rapidly increasing. In attempts to curb the use of psychotropic medicine in the paediatric population, regulatory authorities have issued various warnings about risks associated with use of these products in childhood. Little evidence has been reported about the adverse drug reactions (ADRs) of these medicines in practice. As spontaneous reports are the main source for information about previously unknown ADRs, we analysed data submitted to a national ADR database. The objective was to characterise ADRs reported for psychotropic medicines in the Danish paediatric population over a decade.</p> <p>Findings</p> <p>All spontaneous ADR reports from 1998 to 2007 for children from birth to 17 years of age were included. The unit of analysis was one ADR. We analysed the distribution of ADRs per year, seriousness, age and gender of the child, suspected medicine and type of reported ADR. A total of 429 ADRs were reported for psychotropic medicines and 56% of these were classified as serious. Almost 20% of psychotropic ADRs were reported for children from birth up to 2 years of age and one half of ADRs were reported in adolescents, especially for antidepressants and psychostimulants. Approximately 60% of ADRs were reported for boys. Forty percent of all ADRs were from the category 'nervous and psychiatric disorders'. All but one ADR reported for children below two years were serious and two of these were fatal. A number of serious ADRs reported in children from birth up to 2 years of age were presumably caused by mothers' use of psychotropic medicines during pregnancy.</p> <p>Conclusion</p> <p>The high number of serious ADRs reported for psychotropic medicines in the paediatric population should be a concern for health care professionals and physicians. Considering the higher number of birth defects being reported greater care has to be given while prescribing these drugs for pregnant women.</p

SPARTAN: a global network to evaluate and enhance satellite-based estimates of ground-level particulate matter for global health applications

Ground-based observations have insufficient spatial coverage to assess long-term human exposure to fine particulate matter (PM2.5) at the global scale. Satellite remote sensing offers a promising approach to provide information on both short-and long-term exposure to PM2.5 at local-to-global scales, but there are limitations and outstanding questions about the accuracy and precision with which ground-level aerosol mass concentrations can be inferred from satellite remote sensing alone. A key source of uncertainty is the global distribution of the relationship between annual average PM2.5 and discontinuous satellite observations of columnar aerosol optical depth (AOD). We have initiated a global network of ground-level monitoring stations designed to evaluate and enhance satellite remote sensing estimates for application in health-effects research and risk assessment. This Surface PARTiculate mAtter Network (SPARTAN) includes a global federation of ground-level monitors of hourly PM2.5 situated primarily in highly populated regions and collocated with existing ground-based sun photometers that measure AOD. The instruments, a three-wavelength nephelometer and impaction filter sampler for both PM2.5 and PM10, are highly autonomous. Hourly PM2.5 concentrations are inferred from the combination of weighed filters and nephelometer data. Data from existing networks were used to develop and evaluate network sampling characteristics. SPARTAN filters are analyzed for mass, black carbon, water-soluble ions, and metals. These measurements provide, in a variety of regions around the world, the key data required to evaluate and enhance satellite-based PM2.5 estimates used for assessing the health effects of aerosols. Mean PM2.5 concentrations across sites vary by more than 1 order of magnitude. Our initial measurements indicate that the ratio of AOD to ground-level PM2.5 is driven temporally and spatially by the vertical profile in aerosol scattering. Spatially this ratio is also strongly influenced by the mass scattering efficiency.Fil: Snider, G.. Dalhousie University Halifax; CanadáFil: Weagle, C. L..
