Mapping the Social Organization of Labour in Moscow: Beyond the Formal/informal Labour Dualism
The starting point of this paper is recognition that the depiction of a formal/informal labour dualism, which views formal and informal labour as separate and hostile realms, is inappropriate for capturing the range of labour practices in societies. This is because labour practices cannot be neatly separated into discrete formal and informal realms, the differences within the formal and informal spheres are as great as the differences between the two realms, and formal and informal labour are not always embedded in different economic relations, values and motives. Here, an alternative more nuanced conceptual lens is proposed that resolves these problems and in so doing captures the multifarious labour practices in societies, namely the total social organization of labour (TSOL) perspective. This depicts labour practices as existing along a spectrum from more formal-oriented to more informal-oriented practices and cross-cuts this with a further spectrum from non-monetized, through in-kind and reciprocal labour, to monetized labour. Applying this conceptual lens, the results of a survey of the anatomy of labour practices in an affluent, mixed and deprived district of Moscow, comprising 313 face-to-face interviews, are then analysed. This reveals that socio-spatial variations in the organisation of labour are not solely about the degree of formalization of working life. Instead, this study unravels that populations range from relatively affluent \'work busy\' populations undertaking, and voluntarily selecting from, a multiplicity of labour practices, to relatively disadvantaged \'work deprived\' populations engaged in a narrower range of practices and more commonly out of necessity and in the absence of alternatives. The outcome is call for both the wider application and refinement of this TSOL approach when mapping the social organisation of labour and evaluations of whether the findings from Moscow are more widely valid in other societal contexts.Informal Sector; Labour Practices; Livelihoods; Household Work Practices; Economic Sociology; Uneven Development; Eastern Europe; Russia; Moscow
Varieties of context and informal entrepreneurship: Entrepreneurial activities of migrant youths in rural Ghana
Purpose
The purpose of this paper is to examine the multi-faceted contexts, which influence the motives, decisions and actions that underpin the mundane and lively entrepreneurial practice of migrant youth entrepreneurs (MYEs) within a developing economy context. Moreover, the paper explores the under-researched linkages between migration and informal entrepreneurship.
Design/methodology/approach
Inductive, qualitative field data from a migrant destination, the Ashanti Region in Ghana are analysed, comprising 15 interviews with MYEs who hail from 12 communities in the three Northern Regions of Ghana. The authors introduce a narrative-based approach, which has previously been under-employed within empirical studies of informal entrepreneurship.
Findings
The findings showcase the complex array of opportunities and challenges, which influence individual decisions to engage in informal entrepreneurship. The findings highlight the importance of not only economic rationales but also non-economic rationales for engaging in informal entrepreneurship. Such rationales emerge from the legitimation of informal practices, the social embeddedness of migrant youth within family and community networks and the precarious nature of informal entrepreneurship.
Originality/value
The fine-grained discussion of the findings contributes explicitly to theory by underscoring the diversity of informal entrepreneurship activities. Theoretically, the article demonstrates the need to look beyond narrow economic explanations for why individuals engage in informal entrepreneurship. Taking a more holistic approach to explaining motivations for engaging in informal entrepreneurship, enables more nuanced understandings of the importance of non-economic rationales for individuals, located in specific contextual settings
Costs and clinical benefits of enhanced recovery after surgery (ERAS) in pancreaticoduodenectomy:An updated systematic review and meta-analysis
An investigation into the psychometric properties of the Hospital Anxiety and Depression Scale in patients with breast cancer
BACKGROUND: To determine the psychometric properties of the Hospital Anxiety and Depression Scale (HADS) in patients with breast cancer and determine the suitability of the instrument for use with this clinical group. METHODS: A cross-sectional design was used. The study used a pooled data set from three breast cancer clinical groups. The dependent variables were HADS anxiety and depression sub-scale scores. Exploratory and confirmatory factor analyses were conducted on the HADS to determine its psychometric properties in 110 patients with breast cancer. Seven models were tested to determine model fit to the data. RESULTS: Both factor analysis methods indicated that three-factor models provided a better fit to the data compared to two-factor (anxiety and depression) models for breast cancer patients. Clark and Watson's three factor tripartite and three factor hierarchical models provided the best fit. CONCLUSION: The underlying factor structure of the HADS in breast cancer patients comprises three distinct, but correlated factors, negative affectivity, autonomic anxiety and anhedonic depression. The clinical utility of the HADS in screening for anxiety and depression in breast cancer patients may be enhanced by using a modified scoring procedure based on a three-factor model of psychological distress. This proposed alternate scoring method involving regressing autonomic anxiety and anhedonic depression factors onto the third factor (negative affectivity) requires further investigation in order to establish its efficacy
Enhanced recovery after surgery (ERAS) reduces hospital costs and improve clinical outcomes in liver surgery:A systematic review and meta-analysis
Protective effect of small molecule analogues of the Acanthocheilonema viteae secreted product ES-62 on oxazolone-induced ear inflammation
ES-62 is the major secreted protein of the rodent filarial nematode Acanthocheilonema viteae. The molecule contains covalently attached phosphorylcholine (PC) residues, which confer anti-inflammatory properties on ES-62, underpinning the idea that drugs based on this active moiety may have therapeutic potential in human diseases associated with aberrant inflammation. Here we demonstrate that two synthetic small molecule analogues (SMAs) of ES-62 termed SMA 11a and SMA 12b are protective in the oxazolone-induced acute allergic contact dermatitis mouse model of skin inflammation, as measured by a significant reduction in ear inflammation following their administration before oxazolone sensitisation and before oxazolone challenge. Furthermore, it was found that when tested, 12b was effective at reducing ear swelling even when first administered before challenge. Histological analysis of the ears showed elevated cellular infiltration and collagen deposition in oxazolone-treated mice both of which were reduced by treatment with the two SMAs. Likewise, the oxazolone-induced increase in IFNγ mRNA in the ears was reduced but no effect on other cytokines investigated was observed. Finally, no influence on the mast cell populations in the ear was observed

Feasibility and acceptability of autism adapted safety plans: an external pilot randomised controlled trial.
Autistic people are a high-risk group for self-harm and suicide. There are no evidence-based suicide prevention interventions developed specifically for autistic people. We undertook a pilot feasibility randomised controlled trial of autism adapted safety plans (AASP) to reduce self-harm and suicide for autistic people. This study took place in the United Kingdom and followed a randomised, two-arm, controlled design. Autistic adults (n=53, mean age=39, gender=49% female, 29% not male or female) were recruited via third sector organisations and self-referral between 11.8.21 and 19.10.22. Participants were randomised without stratification to usual care with or without AASP. The AASP was completed by the autistic adults together with someone trained to support them. Research staff who completed follow-up assessments were blind to participant allocation. Primary outcomes were feasibility and acceptability. Participants were assessed at baseline, 1 and 6 months. Primary data were analysed under the intention to treat principle. Study protocol is published. The trial is closed to new participants. This study is registered with the ISRCTN registry, ISRCTN70594445. 53 participants consented, 49 were randomised to either AASP with usual care (n=25) or usual care (n=24). 68% of participants in the AASP arm were satisfied with the AASP and 41% rated it as useable. Feedback on the AASP and research methods were positive with suggested adaptations to some outcome measures. Retention and completion of outcomes measures in both arms was excellent, as was fidelity of delivery of the AASP. Study progression criteria were met, suggesting that the parameters of a future definitive trial of clinical and cost effectiveness of AASP to reduce self-harm and suicide in autistic adults are achievable, with minor recommended adaptions to outcome measures and AASP. Future research should explore the use of AASP in routine clinical practice. This study is funded by the NIHR [Public Health Research Programme (NIHR129196)]. [Abstract copyright: © 2024 The Authors.
Identification and quantification of <i>Acanthamoeba</i> spp. within seawater at four coastal lagoons on the east coast of Australia
Acanthamoeba is an opportunistic free-living heterotrophic protist that is the most predominant amoeba in diverse ecological habitats. Acanthamoeba causes amoebic keratitis (AK), a painful and potentially blinding corneal infection. Major risk factors for AK have been linked to non-optimal contact lens hygiene practices and Acanthamoeba contamination of domestic and recreational water. This study investigated the incidence and seasonal variation of Acanthamoeba spp. within coastal lagoons located on the eastern coast of Australia and then examined the association between Acanthamoeba and water abiotic factors and bacterial species within the water.Water samples were collected from four intermittently closed and open lagoons (ICOLLs) (Wamberal, Terrigal, Avoca and Cockrone) every month between August 2019 to July 2020 except March and April. qPCR was used to target the Acanthamoeba 18S rRNA gene, validated by Sanger sequencing. Water abiotic factors were measured in situ using a multiprobe metre and 16S rRNA sequencing (V3-V4) was performed to characterise bacterial community composition. Network analysis was used to gauge putative associations between Acanthamoeba incidence and bacterial amplicon sequence variants (ASVs).Among 206 water samples analysed, 79 (38.3%) were Acanthamoeba positive and Acanthamoeba level was significantly higher in summer compared with winter, spring, or autumn (p = 0.008). More than 50% (23/45) water samples of Terrigal were positive for Acanthamoeba which is a highly urbanised area with extensive recreational activities while about 32% (16/49) samples were positive from Cockrone that is the least impacted lagoon by urban development. All sequenced strains belonged to the pathogenic genotype T4 clade except two which were of genotype clades T2 and T5. Water turbidity, temperature, intl1 gene concentration, and dissolved O2 were significantly associated with Acanthamoeba incidence (p < 0.05). The ASVs level of cyanobacteria, Pseudomonas spp., Candidatus spp., and marine bacteria of the Actinobacteria phylum and Acanthamoeba 18S rRNA genes were positively correlated (Pearson's r ≥ 0.14). The presence of Acanthamoeba spp. in all lagoons, except Wamberal, was associated with significant differences in the composition of bacterial communities (beta diversity).The results of this study suggest that coastal lagoons, particularly those in urbanised regions with extensive water recreational activities, may pose an elevated risk to human health due to the relatively high incidence of pathogenic Acanthamoeba in the summer. These findings underscore the importance of educating the public about the rare yet devastating impact of AK on vision and quality of life, highlighting the need for collaborative efforts between public health officials and educators to promote awareness and preventive measures, especially focusing lagoons residents and travellers
Small Earth Imaging Spectrometer
Advances in several key sensor technologies make it possible now to build a high performance, very compact and low cost imaging spectrometer for spacebourne terrestrial remote sensing. We describe an instrument based on a highly innovative optical design that incorporates state of the art focal plane arrays, electronics, focal plane cooling and dimensionally stable ceramics for the optical elements and structure. The instrument is optimized for viewing the earth\u27s solid surface and adjacent coastal oceans. It has very high signal-to-noise performance over the full spectral range covered, from 400 to 2450 nanometers (nm). Spectral sampling is in 200 10-nm wide, contiguous bands. The instrument combines a high spatial resolution panchromatic imaging system with a modest spatial resolution imaging spectrometer. It weighs 25 kg, requires less than 100 watts of power, and is approximately 30 by 20 by 10 cm in dimension, fitting well within the capacity of Pegasus-class small spacecraft missions. The instrument is well suited to support studies in earth system science as well as commercial remote sensing. Several applications in these areas will be highlighted to set in context the performance requirements that were used to define the sensor design and choice of sensor technologies
