Published: January 2023

Introduction

Fluctuations in the numbers of patient consultations in hand trauma emergency units are challenging in terms of both scheduling and the provision of sufficient resources. Trauma consultations in general are affected by both temporal and meteorological variables. As the genesis and epidemiology of hand trauma have their own characteristics, this study aimed to identify the influence of temporal and meteorological factors on hand trauma consultations.

Materials and methods

All patients treated for hand trauma in our level one trauma center in 2019 were included in the study population and the data were analyzed in retrospect. The daily weather data, including temperature, sunshine duration, precipitation, humidity and wind speed, as well as temporal factors such as time of day, weekday and public holidays were considered and correlated with patient consultations. Gender differences were studied as well.

Results

We included 4787 hand trauma patients (66.4% male, mean age 38.4 ± 19.3 years, 31.7% occupational injuries). Significantly more consultations occurred on Saturdays as compared to weekdays (14.8 ± 0.6, n = 52 vs. 13.0 ± 0.2, n = 261; p = 0.028), and fewer occurred on official holidays (11.8 ± 0.5, n = 63 vs. 13.4 ± 0.2, n = 302; p = 0.0047). We found a significant positive correlation between daily consultations, sunshine duration (r = 0.14, p = 0.0056) and the mean temperature (r = 0.20, p < 0.0001); in contrast, a significant negative correlation between daily consultations and humidity (r = − 0.17, p = 0.001) was observed. Furthermore, fewer consultations were seen on days with precipitation (12.7 ± 0.3, n = 219 vs. 13.8 ± 0.3, n = 146; p = 0.009). The variation was considerably stronger in men.

Conclusions

Hand trauma consultations increased with increasing temperatures, duration of sunshine, and decreasing humidity. Peak admissions were seen on Fridays and Saturdays. These findings can assist in predicting days with peak admissions to allocate resources appropriately.

Published: January 2023

Purpose

Overweight and obesity are major risk factors for perinatal morbidity and mortality, and the need for bariatric surgery (BS) among fertile-aged women is increasing. This study evaluates the outcome of post-BS pregnancies and deliveries.

Methods

All 20–45-year-old patients delivering between 2004 and 2016 in Finland were included. Patients with previous BS were identified from the hospital discharge register, and the medical birth register was queried for data on pregnancies, deliveries, and perinatal outcomes. The data were matched using personal identification codes, and the outcomes of women with previous BS were compared with those of other pregnancies.

Results

Women with previous BS (n = 314) constituted the bariatric group. When compared with the non-bariatric group (n = 750,019), they were older (p < 0.001), heavier (p < 0.001) and had more previous pregnancies (p < 0.001). The overall incidence of pregnancy-induced hypertension (p = 0.002), gestational diabetes (GDM) (p = 0.018), pre-term contractions (p = 0.023), pre-term delivery (p = 0.003), labour induction (p < 0.001), planned (p = 0.001) and unplanned (p = 0.036) caesarean sections and low birthweight infants (p < 0.001) were significantly higher in the bariatric group. When compared with body mass index–specific categories, the main outcomes were increased incidence of GDM and small for gestational age (SGA) newborns in the bariatric group.

Conclusion

BS can be considered a safe and advisable treatment for obesity among fertile-aged women. The pregnancy outcome is associated with post-BS weight, but the risk for GDM and small for gestational-age newborns is increased.

Published: January 2023

Purpose

Peripheral neuropathy (PN) is common in multiple myeloma (MM) patients. More insight has been gained concerning the role of vitamin D in preventing PN. However, studies evaluating the effects of vitamin D3 supplementation on PN are lacking. The aims of this study are to (1) evaluate the effectiveness of a vitamin D3 regimen on achieving adequate vitamin D levels in deficient MM patients and to (2) exploratively evaluate the effect of vitamin D3 supplementation on PN.

Methods

Thirty-nine MM patients with inadequate (< 75 nmol/L [= 30 ng/mL]) 25-hydroxyvitamin D (25(OH)D) levels were included in this multicenter, prospective, single-arm study, of whom 35 patients completed the study. They received oral vitamin D3 for 6 months according to a dose escalation regimen that consisted of one or two loading doses of 200,000 international units (IU), and maintenance doses of 800, 1600, or 3200 IU/day depending on the 25(OH)D level. A validated questionnaire was used to measure PN.

Results

Median 25(OH)D increased from 38 (IQR 32–52) nmol/L at baseline to 77 (IQR 72–87) nmol/L after 6 months (P < 0.001). Adequate 25(OH)D levels were achieved by 66% of the subjects, and 34% were within the range of 50–75 nmol/L. Furthermore, in 37% of the participants, PN severity decreased (P = 0.007).

Conclusion

The use of substantially higher vitamin D3 doses than recommended in current guidelines resulted in a significant increase in vitamin D levels in MM patients. Furthermore, evaluation of PN showed a significant decrease in PN grading. However, this exploratory evaluation needs further confirmatory research.
Transformer transfer learning emotion detection model: synchronizing socially agreed and self-reported emotions in big data
Authors: Lee Sanghyub John , Lim JongYoon , Paas Leo , Ahn Ho Seok
Published: January 2023

Tactics to determine the emotions of authors of texts such as Twitter messages often rely on multiple annotators who label relatively small data sets of text passages. An alternative method gathers large text databases that contain the authors’ self-reported emotions, to which artificial intelligence, machine learning, and natural language processing tools can be applied. Both approaches have strength and weaknesses. Emotions evaluated by a few human annotators are susceptible to idiosyncratic biases that reflect the characteristics of the annotators. But models based on large, self-reported emotion data sets may overlook subtle, social emotions that human annotators can recognize. In seeking to establish a means to train emotion detection models so that they can achieve good performance in different contexts, the current study proposes a novel transformer transfer learning approach that parallels human development stages: (1) detect emotions reported by the texts’ authors and (2) synchronize the model with social emotions identified in annotator-rated emotion data sets. The analysis, based on a large, novel, self-reported emotion data set (n = 3,654,544) and applied to 10 previously published data sets, shows that the transfer learning emotion model achieves relatively strong performance.
Structuring Life After Death: Plant Leachates Promote CO2 Uptake by Regulating Microbial Biofilm Interactions in a Northern Peatland Ecosystem

Published: January 2023

Shifts in plant functional groups associated with climate change have the potential to influence peatland carbon storage by altering the amount and composition of organic matter available to aquatic microbial biofilms. The goal of this study was to evaluate the potential for plant subsidies to regulate ecosystem carbon flux (CO2) by governing the relative proportion of primary producers (microalgae) and heterotrophic decomposers (heterotrophic bacteria) during aquatic biofilm development in an Alaskan fen. We evaluated biofilm composition and CO2 flux inside mesocosms with and without nutrients (both nitrogen and phosphorus), organic carbon (glucose), and leachates from common peatland plants (moss, sedge, shrub, horsetail). Experimental mesocosms were exposed to either natural sunlight or placed under a dark canopy to evaluate the response of decomposers to nutrients and carbon subsidies with and without algae, respectively. Algae were limited by inorganic nutrients and heterotrophic bacteria were limited by organic carbon. The quality of organic matter varied widely among plants and leachate nutrient content, more so than carbon quality, influenced biofilm composition. By alleviating nutrient limitation of algae, plant leachates shifted the biofilm community toward autotrophy in the light-transparent treatments, resulting in a significant reduction in CO2 emissions compared to the control. Without the counterbalance from algal photosynthesis, a heterotrophic biofilm significantly enhanced CO2 emissions in the presence of plant leachates in the dark. These results show that plants not only promote carbon uptake directly through photosynthesis, but also indirectly through a surrogate, the phototrophic microbes.
RbQE: An Efficient Method for Content-Based Medical Image Retrieval Based on Query Expansion
Authors: Rashad Metwally , Afifi Ibrahem , Abdelfatah Mohammed
Published: January 2023

Systems for retrieving and managing content-based medical images are becoming more important, especially as medical imaging technology advances and the medical image database grows. In addition, these systems can also use medical images to better grasp and gain a deeper understanding of the causes and treatments of different diseases, not just for diagnostic purposes. For achieving all these purposes, there is a critical need for an efficient and accurate content-based medical image retrieval (CBMIR) method. This paper proposes an efficient method (RbQE) for the retrieval of computed tomography (CT) and magnetic resonance (MR) images. RbQE is based on expanding the features of querying and exploiting the pre-trained learning models AlexNet and VGG-19 to extract compact, deep, and high-level features from medical images. There are two searching procedures in RbQE: a rapid search and a final search. In the rapid search, the original query is expanded by retrieving the top-ranked images from each class and is used to reformulate the query by calculating the mean values for deep features of the top-ranked images, resulting in a new query for each class. In the final search, the new query that is most similar to the original query will be used for retrieval from the database. The performance of the proposed method has been compared to state-of-the-art methods on four publicly available standard databases, namely, TCIA-CT, EXACT09-CT, NEMA-CT, and OASIS-MRI. Experimental results show that the proposed method exceeds the compared methods by 0.84%, 4.86%, 1.24%, and 14.34% in average retrieval precision (ARP) for the TCIA-CT, EXACT09-CT, NEMA-CT, and OASIS-MRI databases, respectively.
The SWADE model for landslide dating in time series of optical satellite imagery
Authors: Fu Sheng , de Jong Steven M. , Deijns Axel , Geertsema Marten , de Haas Tjalling
Published: January 2023

Landslides are destructive natural hazards that cause substantial loss of life and impact on natural and built environments. Landslide frequencies are important inputs for hazard assessments. However, dating landslides in remote areas is often challenging. We propose a novel landslide dating technique based on Segmented WAvelet-DEnoising and stepwise linear fitting (SWADE), using the Landsat archive (1985–2017). SWADE employs the principle that vegetation is often removed by landsliding in vegetated areas, causing a temporal decrease in normalized difference vegetation index (NDVI). The applicability of SWADE and two previously published methods for landslide dating, harmonic modelling and LandTrendr, are evaluated using 66 known landslides in the Buckinghorse River area, northeastern British Columbia, Canada. SWADE identifies sudden changes of NDVI values in the time series and this may result in one or more probable landslide occurrence dates. The most-probable date range identified by SWADE detects 52% of the landslides within a maximum error of 1 year, and 62% of the landslides within a maximum error of 2 years. Comparatively, these numbers increase to 68% and 80% when including the two most-probable landslide date ranges, respectively. Harmonic modelling detects 79% of the landslides with a maximum error of 1 year, and 82% of the landslides with a maximum error of 2 years, but requires expert judgement and a well-developed seasonal vegetation cycle in contrast to SWADE. LandTrendr, originally developed for mapping deforestation, only detects 42% of landslides within a maximum error of 2 years. SWADE provides a promising fully automatic method for landslide dating, which can contribute to constructing landslide frequency-magnitude distributions in remote areas.
The Effects of Vibratory and Acoustic Stimulations on Postural Control in Healthy People: A Systematic Review

Published: January 2023

Research on human posture and balance control has grown in recent years, leading to continued advances in their understanding. The ability to maintain balance is attributed to the interplay of the visual, vestibular, and somatosensory systems, although an important role is also played by the auditory system. The lack or deficit in any of these systems leads to a reduced stability that may be counterbalanced by the integration of all the remaining sensory information. Auditory and vibratory stimulation have been found to be useful to enhance balance alongside daily activities either in healthy or pathological subjects; nevertheless, while widely investigated, the literature relating to these approaches is still fragmented. This review aims at addressing this by collecting, organising, and discussing all the literature to date on the effects of the various acoustic and vibratory stimulation techniques available on static upright posture in healthy subjects. In addition, this review intends to provide a solid and comprehensive starting point for all the researchers interested in these research areas. A systematic search of the literature was performed and a total of 33 articles (24 on vibratory stimulation and 9 on acoustic stimulation) were included in our analysis. For all articles, several elements were highlighted including: the study sample, the characteristics of the stimulations, the recording instruments, the experimental protocols, and outcomes. Overall, both stimulations analysed were found to have a positive effect on balance but more research is needed to align those alternative approaches to the traditional ones.
Cuticular Hydrocarbon Polymorphism in a Parasitoid Wasp
Authors: Pokorny Tamara , Ruther Joachim
Published: January 2023

Cuticular hydrocarbons (CHCs) are major constituents of the cuticular lipid layer of insects. They serve not only as a barrier to desiccation, but often additionally mediate communication at close range. The compositions of the CHC profiles, i.e., the specific compounds and their relative amounts, usually differ between species. Additional intraspecific variability can be found between different populations, between colonies and castes of social insects, and between the sexes. Thus, such groups can often be distinguished based on distinctive compounds and/or specific compound ratios. The CHC profile may further be influenced by biotic and abiotic factors, which therefore can impact, e.g., nestmate recognition or mate choice. However, consistent intrasexual variation seems to be rare. Here, we investigated a case of intrasexual CHC variability within a single population of a parasitoid wasp. While wasps of both sexes produced the same set of compounds, the relative amounts of specific compound classes revealed the presence of intrasexual chemical phenotypes. This is, to our knowledge, the first report of three distinct female CHC profile patterns within a population of a solitary insect that uses CHCs for mate recognition. Additionally, male CHC profiles, while overall very similar, could be separated into two chemotypes by multivariate analysis. The study of species exhibiting such intraspecific and intrasexual CHC variation will advance our understanding of the effects of CHC variability on both, desiccation resistance and intraspecific communication.
The Activity of Vossia cuspidata Polysaccharides-Derived Monometallic CuO, Ag, Au, and Trimetallic CuO-Ag-Au Nanoparticles Against Cancer, Inflammation, and Wound Healing

Published: January 2023

The biosynthesis of metal nanoparticles using plant extracts is an eco-friendly and inexpensive solution that has strong potential and applications in science and industry. This study aims to synthesize Cu, Ag, and Au monometallic and trimetallic nanoparticles (NPs) using the extracted polysaccharides (PS) of Vossia cuspidata (Roxb.) Griff. leaves. Besides, the anti-cancer, anti-inflammatory, and wound healing potentials of the synthesized NPs were tested. The synthesized NPs were characterized using standard technological methods. We succeeded in green synthesizing CuO, Ag, Au, monometallic, and CuO-Ag-Au trimetallic NPs. The synthesized NPs had weak cytotoxicity at low concentrations (6.5 µg/ml), but the viability of cancer cells was reduced by increasing the concentration, suggesting that the synthesized NPs have potent anti-cancer properties against the cells. The synthesized NPs had 19.44–45.9 μg/ml cytotoxic activity (IC50) against the MCF-7 cell line, 16.50–51.92 μg/ml against A549, and 115.90–165.9 μg/ml for normal lung cells (WI-38). TMNPs were the most effective cytotoxic agents against all the tested cell lines, followed by AuNPs on MCF-7 and CuONPs on A549. The cotton fabric-treated TMNPs and CuONPs exhibited anti-inflammatory properties greater than fabric-treated AgNPs and AuNPs and showed the highest odema inhibition (84.61% and 79.28%, respectively). In the wound healing assay, CuONPs and TMNPs caused the highest percentages of inhibition (87.82% and 61.98%, respectively) for the wound compared to AgNPs and AuNPs. TMNPs and CuONPs were more efficient in restoring the tissue integrity of wounds than AgNPs and AuNPs. Accordingly, we recommend using TMNPs and CuONPs in the wound healing dressings.

Published: January 2023

At household level, clothes washing has been recognised as an emitter of microplastics (MPs) into the environment and it is supposed that dishwashing is also a source of MPs, although little attention has been paid so far. In this work, the emission of MPs released from dishwashing procedures at household level has been studied. The effect of different parameters such as time, temperature and type of detergent has been analysed. In addition, the MP content of tap water has been evaluated in order to determine its contribution to the MPs in dishwasher effluent. Results showed that when the dishwasher was operated empty with a pre-wash programme (15 min and room water temperature), between 207 and 427 MPs were released per load (3 L), whereas this value increased notably with an intensive programme (164 min and water at 70 °C) (1025–1370 MPs per load, 15 L), which highlighted the effect of temperature and time on MP release. Additionally, when a polypropylene lunch box was washed, the number of MPs released increased by 14 ± 3 MPs and 166 ± 12 MPs of total. Finally, the influence of the use of detergent with the dishwasher empty and containing lunch boxes has been studied. With detergent, 35–54% more MPs were released from dishwasher accessories, whereas no additional release took place from lunch boxes. This work shows for the first time the important contribution of domestic dishwashing to MP pollution and the environmental benefits of using more environmentally friendly materials in both dishwashing machine accessories and food utensils.

Opinion statement

Although chimeric antigen receptor T cell immunotherapy has been successfully applied in patients with hematological malignancies, several obstacles still need to be overcome, such as high relapse rates and side effects. Overcoming the limitations of CAR-T cell therapy and boosting the efficacy of CAR-T cell therapy are urgent issues that must be addressed. The exploration of small-molecule compounds in combination with CAR-T cell therapies has achieved promising success in pre-clinical and clinical studies in recent years. Protein kinase inhibitors, demethylating drugs, HDAC inhibitors, PI3K inhibitors, immunomodulatory drugs, Akt inhibitors, mTOR inhibitors, and Bcl-2 inhibitors exhibited potential synergy in combination with CAR-T cell therapy. In this review, we will discuss the recent application of these combination therapies for improved outcomes of CAR-T cell therapy.

Published: January 2023

Arterial gas embolism following pulmonary barotrauma occurs in 13–24% of cases of diving deaths. The study aimed to evaluate the usefulness of a histomorphometric digital analysis in the detection of air space over-distension due to pulmonary barotrauma. The study was performed on lung parenchyma specimens of 12 divers: six had died due to arterial gas embolism following pulmonary barotrauma (mean age at death of 54 years, range of 41–61 years), and six had drowned in saltwater without a diagnosis of pulmonary barotrauma (mean age at death of 54 years, range of 41–66 years) (positive controls). For negative controls, six cases of non-SCUBA divers (mean age of death of 42 years, range of 23–55 years) who died of intracerebral haemorrhage were evaluated. No significant differences were observed in the characteristics of the air spaces between control groups (positive and negative). However, differences were observed in the area occupied by air spaces and the percentage of air space area when we compared the case group to the controls (p < 0.01); and there was a slight difference in the maximum and minimum diameters of air space (p < 0.05). The mean area occupied by air spaces and the mean percentage of air space were the most useful for discriminating pulmonary barotrauma from other causes of death (100% sensitivity and 91.7% specificity). Based on our study, inclusion of an increased pattern of air spaces as a possible diagnostic criterion for pulmonary barotrauma would be useful in discerning the cause of diving death.
Why increase in telework may have affected employee well-being during the COVID-19 pandemic? The role of work and non-work life domains
Authors: Kaltiainen Janne , Hakanen Jari J.
Published: January 2023

Given that millions of employees switched to mandatory telework during COVID-19, and as teleworking practices are likely to continue, it is essential to understand the potential impact of mandatory and non-flexible teleworking practices on employee well-being. Drawing on Conservation of Resources theory, we find support for resource gains as increase in job control mediates the link between increases in teleworking and improvements in well-being (increases in work engagement and decreases in burnout and job boredom). Conversely, the findings indicate resource losses as loss of social support and higher work-non-work interference explain the deterioration in well-being for those whose teleworking increased since the COVID-19 outbreak. By coupling role depletion and role enrichment theories, we find that employees who had children living at home experienced greater work-non-work interference due to increased teleworking. However, having children also buffered the negative impact of work-non-work interference on well-being. The findings are based on a Finnish population sample collected three months before and after the COVID-19 outbreak in March 2020 (N = 996 of matched respondents) and latent change score analyses of within-person changes. Our results provide new insights regarding the potential impact of teleworking on employee well-being in a context where teleworking is not flexible and self-selected by the employees. Notably, our results draw bridges (rather than burn them) between role depletion and enrichment frameworks as having children may simultaneously be “a burden” and “a gift”.
Prediction via Similarity: Biomedical Big Data and the Case of Cancer Models
Authors: Boniolo Fabio , Boniolo Giovanni , Valente Giovanni
Published: January 2023

In recent years, the biomedical field has witnessed the emergence of novel tools and modelling techniques driven by the rise of the so-called Big Data. In this paper, we address the issue of predictability in biomedical Big Data models of cancer patients, with the aim of determining the extent to which computationally driven predictions can be implemented by medical doctors in their clinical practice. We show that for a specific class of approaches, called k-Nearest Neighbour algorithms, the ability to draw predictive inferences relies on a geometrical, or topological, notion of similarity encoded in a well-defined metric, which determines how close the characteristics of distinct patients are on average. We then discuss the conditions under which the relevant models can yield reliable and trustworthy predictive outcomes.
Sources of knowledge in the firm: a review on influential, internal and contextual factors in innovation dynamics
Authors: Pinto Hugo , Guerreiro Jorge André , Fernández-Esquinas Manuel
Published: January 2023

The sources of knowledge are diverse, as each firm interacts with multiple actors in pursuing its mission: partners and strategic allies, suppliers, customers, competitors, specialist organizations such as knowledge-intensive business services, universities, technology centres, public research organizations, innovation intermediaries and public administration bodies. Different kinds of knowledge, both tacit and codified, are relevant for firms. Nevertheless, knowledge needs to be translated into the capacity to act. Hence, knowledge generation and absorption can be understood as two sides of the same coin and it is necessary to take factors that shape both facets into account, in addition to the relationship between the production, transfer and valorisation of knowledge. This article reviews crucial factors for knowledge in firms, aggregated as influential, contextual and internal. Influential factors are associated with knowledge tacitness and the existing knowledge base, whereas the internal characteristics of the firm are also crucial and concern aspects such as the existing innovation culture, leadership attributes and internal research and development capabilities. Finally, contextual factors, such as the territorial dynamics, are essential as environmental enablers for generating and absorbing knowledge. Together, these factors reinforce the dynamic capabilities of the firm and influence the decision to either engage in open innovation strategies or prioritize actions that protect and codify knowledge, thus affecting the firms’ competitiveness.
Prototypical approach for an individualized standardization process in the context of intelligent construction and automation
Authors: Albus Jutta , Hollmann-Schröter Kirsten Elisabeth
Published: January 2023

Strategies based on an optimal balance between standardization and individualization must be implemented to successfully overcome the current low level of automation in building construction. Project-specific adaptability can be ensured by a combination of automated machine technology and digital planning tools available today. In addition to achieving economic advantages, the focus is on improving sustainability factors, which concern both material consumption and functionality and improved use of resources and energy for building production and operation. The results of research into “lightweight aerogel concrete technology” has shown that an innovative liquid material mixture with insulating properties can be successfully implemented in an automated production process. An adaptive system for standardized wall, ceiling, and floor panels was developed, which can adapt to specific functionality needs and thus address the requirements of individual building tasks while keeping economic as well as architectural factors in mind. The advanced mono-material complies with current European regulations for insulated wall structures, considering the requirements for load-bearing capacity. Due to its homogeneous insulation effect across the entire element section, the aero lightweight concrete allows for intelligent detailing and connection principles and prevents the formation of thermal bridges. The relationship between material composition, material production, construction method, and building operation is essential for a circular planning process. Robotization as a multiple fabrication technology may facilitate these parameters in one cycle. The new technology allows for the crucial transition from research to an end-to-end construction workflow that maps the entire process chain, from concept planning to design and joining principles up to fabrication and assembly.
The Domestication of Competition
Authors: Hearn Jonathan
Published: January 2023

Competition is deeply built into the structures of modern life. It can improve policies, products and services, but is also seen as a divisive burden that pits people against one another. This book seeks to go beyond such caricatures by advancing a new thesis about how competition came to shape our society. Jonathan Hearn argues that competition was 'domesticated', harnessed and institutionalised across a range of institutional spheres in the late eighteenth and early nineteenth centuries. Responding to crises in traditional forms of authority (hereditary, religious), the formalisation of competition in the economy, politics, and diverse new forms of knowledge creation provided a new mode for legitimating distributions of power in the emerging liberal societies. This insightful study aims to improve our ability to think critically about competition, by better understanding its integral role, for good and ill, in how liberal forms of society work.
Animal sheltering: A scoping literature review grounded in institutional ethnography
Authors: Koralesky Katherine E , Rankin Janet M , Fraser David
Published: January 2023

A diverse research literature now exists on the animals, staff and organisations involved in animal sheltering. We reviewed this research through the lens of institutional ethnography, a method of inquiry that focuses on the actual work that people do within institutions. The main topics, identified through a larger ethnographic study of animal sheltering, were: (i) research about shelter staff and officers; (ii) the relinquishment of animals to shelters; and (iii) animals’ length of stay in shelters. After reviewing the literature, we held focus groups with shelter personnel to explore how their work experiences are or are not represented in the research. The review showed that stress caused by performing euthanasia has attracted much research, but the decision-making that leads to euthanasia, which may involve multiple staff and potential conflict, has received little attention. Research on ‘compassion fatigue’ has also tended to focus on euthanasia but a granular description about the practical and emotional work that personnel undertake that generates such fatigue is missing. Published research on both relinquishment and length of stay is dominated by metrics (questionnaires) and often relies upon shelter records, despite their limitations. Less research has examined the actual work processes involved in managing relinquishment as well as monitoring and reducing animals’ length of stay. Institutional ethnography’s focus on people’s work activities can provide a different and more nuanced understanding of what is happening in animal sheltering and how it might better serve the needs of the animals and staff.
Challenges in farmed insect welfare: Beyond the question of sentience
Authors: Barrett Meghan , Fischer Bob
Published: January 2023

The global Insects as Food and Feed (IAFF) industry currently farms over a trillion individual insects a year and is growing rapidly. Intensive animal production systems are known to cause a range of negative affective states in livestock; given the potential scale of the IAFF industry, it is urgent to consider the welfare of the industry’s insect livestock. The majority of the literature on farmed insect welfare has focused on: (i) establishing that insect welfare ought to be of concern; or (ii) extending vertebrate welfare frameworks to insects. However, there are many overlooked challenges to studying insect welfare and applying that knowledge in IAFF industry contexts. Here, we briefly review five of these challenges. We end with practical recommendations for the future study of insect welfare.
Cats just want to have fun: Associations between play and welfare in domestic cats
Authors: Henning Julia , Nielsen Torben , Fernandez Eduardo , Hazel Susan
Published: January 2023

Play is often considered an indicator and promotor of animal welfare and may facilitate closer cat-human relationships. However, few studies have empirically investigated these associations. The current study aimed to investigate play-related factors associated with four welfare outcome measures in cats (Felis catus) including: cat quality of life; cat-guardian relationship quality; problem behaviour prevalence; and behavioural changes. An online survey was developed using demographic information, questions related to play and resources, free text sections and the following validated measures: cat quality of life (QOL), the cat owner relationship scale, and the adult playfulness trait scale. Responses were completed by 1,591 cat guardians from 55 countries. Higher cat playfulness scores and a greater number of games played were significantly associated with higher cat QOL scores while longer amounts of daily play, greater number of games, both cat and guardian initiating play and higher guardian playfulness scores were all significantly associated with higher cat-guardian relationship scores. Exclusively indoor housing was significantly associated with both higher cat QOL and higher cat-guardian relationships scores compared to cats with outdoor access. Behavioural changes associated with distress in cats were reported when play was absent. Play may be an important factor in assessing and maintaining cat welfare. Further research into the mechanisms of how play impacts welfare and cat-guardian relationships is needed.
On higher-order Fourier analysis in characteristic p
Authors: CANDELA PABLO , GONZÁLEZ-SÁNCHEZ DIEGO , SZEGEDY BALÁZS
Published: January 2023

In this paper, the nilspace approach to higher-order Fourier analysis is developed in the setting of vector spaces over a prime field
$\mathbb {F}_p$
, with applications mainly in ergodic theory. A key requisite for this development is to identify a class of nilspaces adequate for this setting. We introduce such a class, whose members we call p-homogeneous nilspaces. One of our main results characterizes these objects in terms of a simple algebraic property. We then prove various further results on these nilspaces, leading to a structure theorem describing every finite p-homogeneous nilspace as the image, under a nilspace fibration, of a member of a simple family of filtered finite abelian p-groups. The applications include a description of the Host–Kra factors of ergodic
$\mathbb {F}_p^\omega $
-systems as p-homogeneous nilspace systems. This enables the analysis of these factors to be reduced to the study of such nilspace systems, with central questions on the factors thus becoming purely algebraic problems on finite nilspaces. We illustrate this approach by proving that for
$k\leq p+1$
the kth Host–Kra factor is an Abramov system of order at most k, extending a result of Bergelson–Tao–Ziegler that holds for
$k< p$
. We illustrate the utility of p-homogeneous nilspaces also by showing that the structure theorem yields a new proof of the Tao–Ziegler inverse theorem for Gowers norms on
$\mathbb {F}_p^n$

G.A. Res. 76/262 on a Standing Mandate for a General Assembly debate when aveto is cast in the Security Council (U.N.)
Authors: Olabuenaga Pablo Arrocha
Published: January 2023

On April 26, 2022, the United Nations General Assembly (UNGA), without a vote, adopted resolution 76/262 entitled “Standing mandate for a General Assembly debate when a veto is cast in the Security Council.” Less than two months later, on June 8, 2022, for the first time in history, the UNGA held a debate specifically to address a veto cast by China and Russia in the Security Council (UNSC). This meeting, convened in accordance with resolution 76/262, represents a great step forward for accountability within the UN system and opens a new chapter regarding the balance of power among the principal organs of the organization. The power dynamics within the UNSC, the demands for a more efficient United Nations, the fact that a meaningful UNSC reform is not in sight, and the current polarization resulting from Russia's war of aggression against Ukraine set the context in which the resolution was adopted.
The Past Explains the Present: Dealing with Anfal in the Kurdistan Region
Authors: Saeed Nahwi
Published: January 2023

“Transitional justice” refers to a set of strategies for promoting reconciliation in societies that have been ravaged by conflict and human rights abuses in the recent past. In some cases, however, the political leaders of post-conflict societies choose not to pursue transitional justice, instead preferring to keep the status-quo peace. This essay explores the situation in the Kurdistan region of Iraq after the genocidal Anfal campaign of the late 1980s. The Kurdish political authorities at the time did not use any transitional justice measure against the Kurds who collaborated in the persecution and killing of their fellow Kurds. Instead, they declared a unilateral amnesty for all collaborators, without the consent of the victims’ families. This paper argues that this grant of “blanket amnesty,” which protected the accused from legal liability at the expense of victims’ right to justice, brought neither justice nor peace. Conversely, it negatively affected the process of democratization, rule of law, and social reconciliation in the region. The paper concludes that justice and lasting peace will not be realized in the region if the abuses of the past are left unaddressed.
Modern Family? The Gendered Effects of Marriage and Childbearing on Voter Turnout

Published: January 2023

In many democracies, gender differences in voter turnout have narrowed or even reversed. Yet, it appears that women participate more in some circumstances and men in others. Here we study how life trajectories – specifically, marriage and having children – will impact male and female turnout differently, depending on household-level context. To this end, we leverage a unique administrative panel dataset from Italy, an established democracy where traditional family structures remain important. Our within-individual estimates show that marriage increases men's participation to women's higher pre-marital levels, particularly so in low-income families. We also find that infants depress maternal turnout, especially among more traditional families, whereas primary school children stimulate paternal turnout. Exploring aggregate-level consequences, we show that demographic trends in marriage and fertility have contributed to recent shifts in the gender composition of the electorate. Together, our results highlight the importance of the family as a variable in political analyses.
“The Kurds Have Not Made Love Their Aim”: Love, Sexuality, Gender, and Drag in Ehmedê Xanî's Mem û Zîn
Authors: Leezenberg Michiel
Published: January 2023

This paper explores the concepts and norms of gender and sexuality in Ehmedê Xanî's 17th-century mathnawi poem Mem û Zîn, nowadays regarded as the Kurdish national epic. A reading of this poem with the aid of the conceptual tools of gender studies and the history of sexuality reveals how different its norms and concepts are not only from modern Kurdish ones, but also from those of classical Persian literature. Although the poem does not hint at any taboo concerning male love for beardless boys, it does display a remarkable asymmetry between male and female same-sex desire; it also displays distinct views of legitimate and transgressive sexuality. Thus, this poem encourages a more historicizing view of the gendered and sexual dimensions of modern (Kurdish and other) nationalism, and a greater attention for the distinct characteristics of vernacular literatures within the premodern ‘Persianate cosmopolitan.’
War Did Make States: Revisiting the Bellicist Paradigm in Early Modern Europe

Charles Tilly's classical claim that “war made states” in early modern Europe remains controversial. The “bellicist” paradigm has attracted theoretical criticism both within and beyond its original domain of applicability. While several recent studies have analyzed the internal aspects of Tilly's theory, there have been very few systematic attempts to assess its logic with regard to the territorial expansion of states. In this paper, we test this key aspect of bellicist theory directly by aligning historical data on European state borders with conflict data, focusing on the period from 1490 through 1790. Proceeding at the systemic, state, and dyadic levels, our analysis confirms that warfare did in fact play a crucial role in the territorial expansion of European states before (and beyond) the French Revolution.
Transforming Familialistic Youth Welfare Policies in East Asia: A Comparative Analysis of Changes in Higher Education Support Policies in Korea and Japan
Authors: Park Hyewon , Sakai Kosuke
Published: January 2023

In East Asia, higher education support policies (HESPs), as the core of the social policies targeting young people, have undergone a significant transformation since the 2000s. The aim of this article is to articulate the reformation process of HESPs by focusing on the National Student Loan system and to investigate whether support for youth is still considered a family responsibility in the post-2000s environment. The findings offer a crucial clue in understanding the transformation of the familialistic East Asian welfare regime. The analysis reveals that Japan continues to respond to the expansion of youth support through family policy, but Korea is attempting to provide support for youth directly to individuals as an independent welfare target. This implies that HESPs are gradually losing their family-oriented characteristics, although these characteristics remain present in Japan, and that the familialistic East Asian welfare regime itself may transform in the future.
Mapping Shifts in Russian and European Welfare Polities: Explaining Policy Responses to Shared New Social Risks
Authors: Cook Linda J. , Titterton Mike
Published: January 2023

Since 2000, literature on West (EU15) and East-Central European (EU8) welfare states has focused on a set of ‘new social risks’ including insecure employment and income, population ageing, unsustainable social security systems, and large-scale international immigration. Our State-of-the-Art (SOTA) article brings Russia into the dialogue on ‘new social risks’. We show that broadly similar structural changes in industrial economies, labour markets and demographic patterns ended the post-World-War-Two (WWII) ‘Golden Age’ of welfare expansion in both the EU15 and communist states. Shared new social risks rose to the top of policy agendas. Governments responded mainly, though not exclusively, with liberalising, privatising and exclusionary policies. The SOTA compares their policy responses, specifically pension system reforms, demographic (pro-natalist and family) policies, and integration of immigrants. We find both convergence and divergence based on states’ differing welfare legacies. The conclusion considers path-departing ‘emergency Keynesian’ responses to the COVID-19 crisis, and renewed attention to Beveridge welfare models.

Summary: Vascular handlebar syndrome with blunt injury of the common femoral artery is a rare vascular trauma mechanism, with high possibility of being missed or delayed. We present two cases of vascular handlebar syndrome treated in our hospital and a systematic review of the literature using MEDLINE and SCOPUS databases. Literature review identified 20 similar cases. The median age of patients was 18 years, and in vast majority males in gender. In most cases, the common femoral artery injury was an intimal flap and lumen occlusion with intramural thrombosis followed by transection and intimal injury without occlusion or thrombosis. The median time between injury and diagnosis/treatment was half an hour. Clinical presentation ranged from asymptomatic to acute limb ischemia. The grade of acute ischemia was mostly Rutherford class I (n=14), while acute IIa (n=4), chronic ischemia (n=3), and no ischemia (n=1) were also noticed. The correct diagnosis was revealed by clinical examination only (n=1), or by the combination of clinical and imaging techniques including computed tomography angiography (n=7) and duplex ultrasonography (n=4) or both (n=10). Management of the handlebar trauma syndrome injuries was surgical in most cases. Outcome was favorable in all patients. Vascular handlebar syndrome is extremely rare and high suspicion is required for early diagnosis and definitive treatment, as the early management is effective and crucial for averting the devastating consequences. An individualized approach to the vascular trauma patient is to be applied with considerations taken to the age of the patient, the mechanism of the injury, the anatomy of the lesion, and symptomatology of the case.
Conducting Space Physics Research: Wind the Frog, Work Hard, and Be Nice

This report briefly summarizes the key mentors in my scientific career and some lessons learned from those influential people. My primary advice to others: it is okay to do something wrong. By doing science we are doing something hard that, by definition, has not been done before. I believe that impostor syndrome is a real threat to researcher wellbeing and we should acknowledge its presence and support each other to get through it. Regarding an approach to science, I encourage you to get started and make something bad. Also, take time for yourself, it really does help your productivity. To lead others, I recommend to be enthusiastic, actively listen, and make connections across disciplines. I think it is important to foster creativity in those around you. I advocate that you actively make the future that you want to have.
