Labour Law, now in its third edition, is a well established text which offers a comprehensive and critical account of the subject by a team of prominent labour lawyers. It examines both collective labour relations and individual employment rights, including equality law, and does so while having full regard to the international labour standards as well as the implications of Brexit. Case studies and reports from government and other public agencies illuminate the text to show how the law works in practice, ensuring that students acquire not only a sophisticated knowledge of the law but also an appreciation of its purpose and the complexity of the issues which it addresses.
Today, India is widely celebrated as the world's largest democracy. However, not all groups experience India's political institutions the same way. This book draws on extensive interviews with longtime Dalit (ex-Untouchable) activists and original archives of party documents to explore the democratic transformation of one of India's most prominent Dalit-led parties, the Viduthalai Chiruthaigal Katchi (VCK; Liberation Panthers Party). Through a historical and ethnographic account of the VCK's transition from boycotts to ballots, this book provides a novel perspective on India's democratic trajectory, as well as its limits. Whereas VCK leaders initially viewed elections as an instrument to spur development and contest power asymmetries, they would come to recognize that democratic institutions can equally function as a means of containment, and control. The research shows how democratic politics opened new space for Dalit political advancement while simultaneously imposing unique constraints on these leaders that would reconfigure very nature of their politics.
The over consumption of high fat, sugar, and salt foods increases population risk of overweight, obesity and diet-related noncommunicable diseases. The food environment mediates consumer food choices and thus plays an important role in diet quality and related health outcomes. The built food environment, where most people in high income countries access their food, has been found to be obesogenic. The aim of this review was to investigate the healthfulness of the supermarket food environment. Supermarkets are an important source of healthy foods in the built food environment. However, there are disparities in access to supermarkets, and in several countries, supermarkets located in areas of higher deprivation have an unhealthier consumer food environment. This double burden limits access to healthy foods amongst lower socio-economic groups, contributing to widening disparities in food-related ill health. There is a strong body of evidence supporting improved purchase of healthy foods by increasing the healthfulness of the supermarket consumer food environment. Voluntary measures co-designed with retailers to improve the healthfulness of the supermarket consumer food environment through restriction of product placement and private label reformulation have led to an increase in healthier food purchases. However, evidence also shows that mandatory, structural changes are most effective for improving disparities in relation to access to healthy food and diet-related ill health. Future research and policy related to the supermarket food environment should consider equitable access to healthy sustainable foods in the context of growth in online supermarkets.
It is a real pleasure for Mrs Seitz and me to come to Melbourne, one of the truly great cities of the world. I am especially gratified to be speaking in the city where Prime Minister Robert Menzies resided.
I express my gratitude to the University of Virginia for affording me the opportunity and honour of delivering the first Menzies lectures in Australia. By the same token, I thank the Australian National University and the Sir Robert Menzies Memorial Trust for their support of a lecture program designed to further enhance the understanding of our legal systems.
I have read a good deal of material about your country over the past few months. Much of it stressed that we share the English language. That is certainly true but, if Australia is anything like the United States, while we share the same general vocabulary, the younger generation has its own unique language. Fortunately, our legal language is largely interchangeable.
Despite high levels of depression and anxiety, there is relatively little attention to psychological treatment approaches to mental health issues for older adults living in nursing homes. Recent studies support the use of cognitive behaviour therapy (CBT) in this population and here we aim to highlight how CBT can be successfully adapted and implemented with beneficial results. The ELders AT Ease (ELATE) program is a unique service delivery model illustrating delivery of CBT with older adults living in nursing homes. The six modules forming the program, based on CBT, are described. A systems wide approach to delivery is emphasised and illustrated through two clinical case descriptions. Innovative mental health programs can have positive benefits for both residents and staff and support the use of CBT in this vulnerable and under-served client group.
Key learning aims
(1) Knowledge of the content and application of CBT for older adults living in nursing homes.
(2) Understanding of CBT session structure as applied to older adults living in nursing homes.
(3) Recognising and utilising specific strategies to highlight a systemic approach as central to implementing CBT strategies, such as behavioural activation and reminiscence, with considered involvement by staff and family.
Rules of origin under the African Continental Free Trade Area (AfCFTA) Agreement constitute a vital trade instrument that forestalls freeriding by ensuring that only originating products and services benefit from preferential treatment within the free trade area. Functional rules of origin in design and implementation foster the sourcing of value content by producers, manufacturers and enterprises within Africa in accordance with the governing treaty. The sourcing of value content by producers, manufacturers and enterprises within Africa promotes economic activities, measured industrialization and socio-economic development. While the AfCFTA Agreement recognizes the capacities of both rules of origin and regional value chains, each standing alone or acting in a complementary manner to promote African development, a successful outcome will be determined by a critical adjustment that improves capacity and capability. Arguably, state parties to the AfCFTA Agreement should implement strategies for upscaling preference utilization and value chain growth, infrastructural investment and interventions that stimulate value chain trade.
Two studies were conducted in 2022 and 2023 near Rocky Mount and Clayton, NC, to determine the optimal granular ammonium sulfate (AMS) rate and application timing for pyroxasulfone-coated AMS. In the rate study, AMS rates included 161, 214, 267, 321, 374, 428, and 481 kg ha-1, equivalent to 34, 45, 56, 67, 79, 90, and 101 kg N ha-1, respectively. All rates were coated with pyroxasulfone at 118 g ai ha-1 and top-dressed onto 5- to 7-leaf cotton. In the timing study, pyroxasulfone (118 g ai ha-1) was coated on AMS and top-dressed at 321 kg ha-1 (67 kg N ha-1) onto 5- to 7-leaf, 9- to 11-leaf, and first bloom cotton. In both studies, weed control and cotton tolerance to pyroxasulfone-coated AMS was compared to pyroxasulfone applied postemergence (POST) and postemergence-directed (POST-directed). The check in both studies received non-herbicide-treated AMS (321 kg ha-1). Before treatment applications, all plots (including the check) were maintained weed-free with glyphosate and glufosinate. In both studies, pyroxasulfone applied POST was most injurious (8 to 16%), while pyroxasulfone-coated AMS resulted in ≤ 4% injury. Additionally, no differences in cotton lint yield were observed in both studies. With the exception of the lowest rate of AMS (161 kg ha-1; 79%), all AMS rates coated with pyroxasulfone controlled Palmer amaranth ≥ 83%, comparable to pyroxasulfone applied POST (92%) and POST-directed (89%). In the timing study, the application method did not affect Palmer amaranth control; however, applications made at the mid- and late timings outperformed early applications. These results indicate pyroxasulfone-coated AMS can control Palmer amaranth comparable to pyroxasulfone applied POST and POST-directed, with minimal risk of cotton injury. However, the application timing could warrant additional treatment to achieve adequate late-season weed control.
Academic-community research partnerships focusing on addressing the social determinants of health and reducing health disparities have grown substantially in the last three decades. Early-stage investigators (ESIs), however, are less likely to receive grant funding from organizations like the National Institutes of Health, and we know little about the facilitators and barriers they face on their career journeys or the best ways to support them and their community research partnerships. This study examines ESIs’ experiences with a program that funded and supported their community-partnered pilot health disparities research.
Methods:
Fourteen ESIs from five cohorts of pilot investigators participated in in-depth focus groups between April 2020 and February 2024. Two reviewers independently identified significant quotes and created codes. Thematic analysis was used to develop relevant themes.
Results:
The overarching theme was that the program was a launch pad for the ESIs’ research careers. Four distinct sub-themes contributing to the launch pad theme were: (1) ESI Growth & Adaptation; (2) Community and Support; (3) The Value of Collaboration and Partnership; (4) Need for Effective Mentorship. The results suggest the program offered ESIs and community partners substantial, unique support and resources, but challenges remained.
Conclusions:
Future programs helping ESIs who conduct community-engaged research to launch their research careers should consider implementing tailored support while offering strategies to eliminate or reduce institutional barriers, including strengthening mentoring.
To compare the incidence of surgical site infection (SSI) between cefazolin 3 g and 2 g surgical prophylaxis in patients weighing ≥120 kg that undergo elective colorectal surgery.
Methods:
A multicenter, retrospective cohort study was performed utilizing a validated database of elective colorectal surgeries in Michigan acute care hospitals. Adults weighing ≥120 kg who received cefazolin and metronidazole for surgical prophylaxis between 7/2012 and 6/2021 were included. The primary outcome was SSI, which was defined as an infection diagnosed within 30 days following the principal operative procedure. Multivariable logistic regression was used to identify variables associated with SSI; the exposure of interest was cefazolin 3 g surgical prophylaxis.
Results:
A total of 581 patients were included; of these, 367 (63.1%) received cefazolin 3 g, while 214 (36.8%) received 2 g. Patients who received cefazolin 3 g had less optimal antibiotic timing (324 [88.3%] vs 200 [93.5%]; P = .043) and a higher receipt of at least 1 of the prophylaxis antibiotics after incision (22 [6%] vs 5 [2.3%]; P = .043). There was no SSI difference between cefazolin 3 g and 2 g cohorts (23 [6.3%] vs 16 [7.5%], P = .574). When accounting for age, smoking status, and surgical duration, cefazolin 3 g was not associated with a reduction in SSI (adjOR, .64; 95%CI, .32–1.29).
Conclusions:
Surgical prophylaxis with cefazolin 3 g, in combination with metronidazole, was not associated with decreased SSI compared to 2 g dosing in obese patients undergoing elective colorectal surgery.
Defamatory publications may carry any number of related or distinct imputations. Complexities arise where a plaintiff selects one or more imputations for complaint, but ignores other imputations carried by the same publication. In England and Wales, the so-called Polly Peck principle permits defendants to plead and justify an imputation other than one complained of by the plaintiff but bearing a common sting with such an imputation. The Polly Peck principle has not been good law in Australia for more than 20 years. The statutory defence of contextual truth in Australia’s uniform defamation laws, however, permits a defendant to plead and justify imputations that are ‘in addition to’ those complained of by the plaintiff and affords a complete defence where, having regard to the substantial truth of those contextual imputations, the imputations complained of by the plaintiff do not further harm the reputation of the plaintiff. As enacted, the defence was infected with a serious drafting error. This article looks at the implications of the reformulation of the contextual truth defence effected by the recent amendments to Australia’s uniform defamation laws. It posits that those implications are considerably broader than have been recognised to date. It argues that the reformulated defence not only corrects the drafting error in the original defence of contextual truth but also resurrects the Polly Peck principle in Australia and substantially neuters 20 years of confused jurisprudence concerning the extent to which a defendant is or should be constrained by the imputations pleaded by the plaintiff.
The intraclass correlation, ρ, is a parameter featured in much psychological research. Two commonly used estimators of ρ, the maximum likelihood and least squares estimators, are known to be negatively biased. Olkin and Pratt (1958) derived the minimum variance unbiased estimator of the intraclass correlation, but use of this estimator has apparently been impeded by the lack of a closed form solution. This note briefly reviews the unbiased estimator and gives a FORTRAN 77 subroutine to calculate it.
In this paper the usual two-set Guttman simplex model is extended to three sets. The axiomatic foundations of this extention are presented. Two cases are discussed. In Case 1 there is a three-set joint order, while in Case 2 there is a two-set joint order consistent across all levels of the third set. Case 2 represents the first clear formulation of a longitudinal developmental scale. The model is discussed in terms of its most straightforward application, longitudinal developmental data, and in terms of other possible applications.
We present a re-discovery of G278.94+1.35a as possibly one of the largest known Galactic supernova remnants (SNRs) – that we name Diprotodon. While previously established as a Galactic SNR, Diprotodon is visible in our new Evolutionary Map of the Universe (EMU) and GaLactic and Extragalactic All-sky MWA (GLEAM) radio continuum images at an angular size of $3{{{{.\!^\circ}}}}33\times3{{{{.\!^\circ}}}}23$, much larger than previously measured. At the previously suggested distance of 2.7 kpc, this implies a diameter of 157$\times$152 pc. This size would qualify Diprotodon as the largest known SNR and pushes our estimates of SNR sizes to the upper limits. We investigate the environment in which the SNR is located and examine various scenarios that might explain such a large and relatively bright SNR appearance. We find that Diprotodon is most likely at a much closer distance of $\sim$1 kpc, implying its diameter is 58$\times$56 pc and it is in the radiative evolutionary phase. We also present a new Fermi-LAT data analysis that confirms the angular extent of the SNR in gamma rays. The origin of the high-energy emission remains somewhat puzzling, and the scenarios we explore reveal new puzzles, given this unexpected and unique observation of a seemingly evolved SNR having a hard GeV spectrum with no breaks. We explore both leptonic and hadronic scenarios, as well as the possibility that the high-energy emission arises from the leftover particle population of a historic pulsar wind nebula.
Weight loss results in obligatory reductions in energy expenditure (EE) due to loss of metabolically active fat-free mass (FFM). This is accompanied by adaptive reductions (i.e. adaptive thermogenesis) designed to restore energy balance while in an energy crisis. While the ‘3500-kcal rule’ is used to advise weight loss in clinical practice, the assumption that EE remains constant during energy restriction results in a large overestimation of weight loss. Thus, this work proposes a novel method of weight-loss prediction to more accurately account for the dynamic trajectory of EE. A mathematical model of weight loss was developed using ordinary differential equations relying on simple self-reported inputs of weight and energy intake to predict weight loss over a specified time. The model subdivides total daily EE into resting EE, physical activity EE, and diet-induced thermogenesis, modelling obligatory and adaptive changes in each compartment independently. The proposed model was tested and refined using commercial weight-loss data from participants enrolled on a very low-energy total-diet replacement programme (LighterLife UK, Essex). Mathematical modelling predicted post-intervention weight loss within 0.75% (1.07 kg) of that observed in females with overweight or obesity. Short-term weight loss was consistently underestimated, likely due to considerable FFM reductions reported on the onset of weight loss. The best model agreement was observed from 6 to 9 weeks where the predicted end-weight was within 0.35 kg of that observed. The proposed mathematical model simulated rapid weight loss with reasonable accuracy. Incorporated terms for energy partitioning and adaptive thermogenesis allow us to easily account for dynamic changes in EE, supporting the potential use of such a model in clinical practice.
