Shear resistance evolution of geogrid–aggregate interfaces under direct shear: insights from 3D DEM simulations
Authors: Jia Yafei , Zhang Jun , Ngo Trung , Zheng Yewei
Published: February 2024

This paper presents a mesoscopic evaluation of the shear resistance evolution of geogrid–aggregate interfaces subjected to direct shear loading. A three-dimensional discrete element method model was developed based on experimental data. The tensile response of geogrid were simulated through a series of calibration tests. Aggregate with complex particle shapes were simulated to accurately capture the interlocking effect among aggregates based on the real particle surface. The individual shear resistance components were quantified based on particle displacement field and contact distribution characteristics. The influences of aperture–aggregate size ratio and geogrid stiffness on the shear resistance components are discussed. The results indicate that the peak value of shear resistance component follows a descending order from frictional resistance of aggregate, to passive resistance of transverse rib, and to geogrid–aggregate interface frictional resistance. During the shear process, the frictional resistance of aggregate becomes active first, followed by the geogrid–aggregate interface frictional resistance, and then the development of passive resistance of transverse ribs starts with a certain lag. Optimizing the geogrid–aggregate size ratio and utilizing geogrids with higher rib stiffness could enhance the passive resistance of transverse ribs but would not significantly affect the geogrid–aggregate interface frictional resistance and frictional resistance of aggregate.

Published: February 2024

While the topic of investigating user experience with immersive services, such as Social Virtual Reality (VR), is starting to gain traction in the research community, the unique case of multiplayer VR games requires a more specific approach. Attempts to investigate user experiences with this complex, multidimensional service are hindered by the absence of specific standards and guidelines going beyond what we know about non-immersive gaming. In this article, we present the results of a user study (N = 32) exploring participants’ experience of playing two competitive VR games of different genres (shooter, sports game), as we focus on three distinct facets of multiplayer VR gaming—network, interpersonal competitiveness, and social interaction. Furthermore, approaching the issue from the perspective of Quality of Experience researchers looking to conduct future user studies on the topic, we also present our findings as a way to shed light on factors that need further consideration, especially in the context of participant recruitment and methodology design, such as the choice of access network to be used for testing, and the issue of matchmaking study participants based on skill and prior relationship.

Published: February 2024

We combined invasive estimates of left atrial pressure with noninvasive left atrial volume measurements made at rest and during exercise in healthy humans. Left atrial pressure and volume both increased with exercise, though the pressure increase was relatively greater, and calculated compliance decreased modestly while estimated peak wall stress nearly doubled. Our results demonstrate left atrial loading during exercise in healthy older adults and provide insight into how the left atrium mediates cardiopulmonary interactions.

Application of Dayak Onion (Eleutherine bulbosa Urb.) as a Preservative for Animal Protein: Chicken Meat
Authors: Riadh Dellysa Naomi , Paramita Swandari , Yadi
Published: February 2024

The adoption of chicken meat as the primary protein source remains limited in Indonesia due to restrictions on its shelf life. Marinating chicken meat with Dayak onion, known for its antibacterial and antioxidant characteristics, can prolong the meat's shelf life. This research evaluates the efficacy of Dayak onion as a natural preservative for animal protein, specifically chicken meat. The study used a qualitative experimental design featuring both control and treatment groups. The experiment involved testing the pH value and cooking loss value of chicken meat that has been marinated with Dayak onion powder (treatment) and chicken meat that had not been marinated (control). The process of data analysis commenced with the application of the Saphiro-Wilk Test to ascertain the nature of the distribution. If the distribution is found to be normal, the subsequent step involves conducting the Independent-T test. Conversely, if the distribution is determined to be non-normal, the Mann-Whitney Test is employed instead. The research findings indicated that Dayak onion has a notable effect on maintaining the pH level of chicken flesh after 9 hours, as opposed to untreated chicken meat (p0.05). The overall findings demonstrate the capacity of Dayak onion as an organic preservative for chicken meat.

This study delves into the crucial theme of enhancing income-generating capacity, recognizing its pivotal role in meeting basic human needs and catalyzing prosperity within communities. The motivation behind this research lies in addressing this significant issue through the lens of microfinancing, a viable solution to the identified problem. Focusing on a group of microfinancing units strategically located in North Cotabato, Philippines, this study follows the experiences of personnel within these units. The integration of digitization into their operational procedures aimed to elevate service efficiency, providing a contemporary solution to the challenges faced. The research methodology employed was qualitative, utilizing purposive sampling to gain in-depth insights. Observations, interviews, and informal conversations with key informants, including loan officers, branch managers, and an area monitor, were integral to the inquiry. Both physical and electronic documents played a crucial role in enriching the data collected. Specifically, the study aimed to identify both digitized and non-digitized operational procedures, elucidate the experiences of microfinancing employees concerning these procedures, observe the effects of digitization, and pinpoint immediate improvements resulting from digitization. Key conclusions emerged from the study. Notably, loan processing was identified as the sole procedure yet to undergo digitization. The digitized procedures, encompassing data management, loan disbursement, repayment tracking, and financial reporting, demonstrated notable advantages, characterized by increased speed and reduced errors. Importantly, personnel satisfaction with digitized operational procedures witnessed a positive upturn. Identified improvements that underscore these findings include digitizing loan processing, optimization of loan officers' client-handling capacity, and fortifying institutional data security.

Kidney Function Trajectories and Right Heart Failure Following LVAD Implantation
Authors: Walther Carl P. , Civitello Andrew B. , Lamba Harveen K. , Mondal Nandan K. , Navaneethan Sankar D.
Published: February 2024

Background

Preoperative kidney dysfunction is a risk factor for right heart failure (RHF) after implantation of a left ventricular assist device (LVAD). However, characteristic kidney function trajectories before and after post‐LVAD RHF are uncertain, so we investigated this.

Methods and Results

We identified individuals who received primary continuous‐flow LVAD implantation from July 1, 2014 to December 31, 2017 in the Interagency Registry for Mechanically Assisted Circulatory Support (INTERMACS) data set. Incident RHF was ascertained using the INTERMACS definition at 1 and 3 months and classified as transient or persistent. Kidney function trajectories before and after RHF onset, and relationships of baseline kidney function with RHF risk at the different time points, were assessed. We identified 8076 LVAD recipients who met inclusion criteria. Incident RHF was present at 1 month in 26.4%. There were 4850 individuals with follow‐up at 3 months, with incident RHF in 4.2%. Kidney function trajectories differed from pre‐LVAD implantation to 1‐month follow‐up by RHF category, with those developing persistent RHF having no improvement in baseline kidney function. For trajectories before the 3‐month RHF ascertainment time, the shape was similar for those with and without RHF, with lower estimated glomerular filtration rate levels among those who developed RHF. Baseline estimated glomerular filtration rate levels below the normal range were associated with higher risk of RHF at 1 and 3 months.

Conclusions

In LVAD recipients, preimplantation kidney function and subsequent kidney function trajectories differed substantially by RHF at 1 and 3 months postimplantation, even after adjustment for several confounders. This may demonstrate bidirectional associations between kidney function and right ventricular function in LVAD recipients.
Schizophrenia and Types of Stroke: A Mendelian Randomization Study
Authors: Nakada Shinya , Ho Frederick K. , Celis‐Morales Carlos , Pell Jill P.
Published: February 2024

Background

Previous studies suggest an association between schizophrenia and stroke, but no studies have investigated stroke subtypes. We examined potential causal associations between schizophrenia and a range of atherosclerotic, embolic, and hemorrhagic stroke outcomes.

Methods and Results

Two‐sample Mendelian randomization analyses were conducted. The summary‐level data (restricted to European ancestry) were obtained for schizophrenia and stroke: ischemic stroke, large‐artery stroke, small‐vessel stroke, cardioembolic stroke, and intracerebral hemorrhage. The associations between schizophrenia and each outcome were analyzed by an inverse variance weighting method primarily and Mendelian randomization Egger, weighted median, and weighted mode subsequently. The presence of pleiotropy was also tested by Cochran
Q
statistic,

index, and Mendelian randomization Egger intercept with scatter and funnel plots. We found associations between schizophrenia and cardioembolic stroke (odds ratio [OR], 1.070 [95% CI, 1.023–1.119]) and intracerebral hemorrhage (OR, 1.089 [95% CI, 1.005–1.180]) using inverse variance weighting. Little evidence of associations with the other stroke subtypes was found. Different Mendelian randomization methods corroborated the association with cardioembolic stroke but not intracerebral hemorrhage.

Conclusions

We have provided evidence of a potentially causal association between schizophrenia and cardioembolic stroke. Our findings suggest that cardiac evaluation should be considered for those with schizophrenia.
Growth and reproduction of the shrimp population in a lagoon system in southern Benin (West Africa)

Published: February 2024

The aim of this work was to characterize the growth and reproduction dynamics of shrimp in the Lac Nokoué-Chenal de Cotonou complex. The results of one year’s sampling from five stations (North, South, East, Central and West) of the lagoon complex revealed that linear growth in size in Lake Nokoué is decreasing over time in Macrobrachium macrobrachion (the most representative species of the genus Macrobrachium), but positive in Penaeus notialis (the most representative species of the genus Penaeus). Size-weight relationships indicate that the lowest growth coefficient () is obtained in immature males of Macrobrachium felicinum, while the highest growth coefficient () is obtained in mature females of Macrobrachium vollenhovenii, with an average of 2.84 for all shrimp species over both sexes considered. The test indicated that only the species Macrobrachium vollenhovenii has a significant sexual imbalance in favour of females in Lake Nokoué. Fisher’s Least Significant Difference test indicated that the estimated first sexual maturity sizes in Macrobrachium vollenhovenii and M. macrobrachion are significantly different from those estimated in M. felicinum at the threshold. However, the same test indicates that there is not enough evidence to differentiate the sizes of first sexual maturation in M. vollenhovenii and M. macrobrachion. This work revealed that Penaeus monodon was the only species to show better positive growth within all its groups in Lake Nokoué while exposed to anthropogenic effects. A gradual average increase in the size of Penaeus notialis in Lake Nokoué is found between the beginning and end of the saline intrusion (which confirms the life cycle of the species presented). Species of the genus Macrobrachium showed good reproductive capacity, with the absence of sexually mature Penaeus in this lagoon.
The impact of an abiotic variable, temperature, on larvae of the blue crab, Callinectes sapidus Rathbun, 1896 (Brachyura, Portunidae)
Authors: Gencer Övgü
Published: February 2024

Reductions in the size of mature blue crabs, Callinectes sapidus, which are commercially harvested, are of concern to the aquaculture industry. Through their role in the production of viable offspring, aquaculturists focus their attention in particular on female crabs, although the phenomenon will, of course, also affect the males. Meanwhile, decreases in size at maturity throughout the crab population may be the result of temperature alterations, at present also due to global climate change. Temperature-based shifts in growth can lead to changes in reproductive efficiency, as well as in size and age at maturity. In this study, the effects of temperature on the moulting frequency of blue crabs were investigated and survival rates have been calculated. The purpose of this study was to investigate the temperature dependence of survival and of the moulting processes for blue crab larvae, and to determine the effect of increasing temperature on moulting. The stages from zoea-1 to zoea-5 were examined at 16, 22, 26 and 30°C. The results show that there is a significant difference in growth and moulting, depending on the rearing temperature. As the temperature increases, the interval between moulting days can be seen to be shortened, and increasingly so with the progress in the growth of the crabs. Moulting-interval days became less with the growth of the crabs. The effect of a rise in temperature on growth per moult is also significant, and along the temperature range tested the optimum temperature was found to be 26°C. A reduction in the length of the intermoult period was observed from the lowest to the optimum temperature, while a sudden, sharp increase in the intermoult period above 26°C was observed as well.

A body mass index of more than 23 kg/m2 refers to being overweight. When overweight is not treated well, it can lead to obesity which is the condition of accumulation of excess adipose tissue. Obesity increases the risk of metabolic disease and physical activity has been known to prevent it. Irisin has been established to have a positive correlation with body fat burning. The purpose of this study is to analyse the acute effect of high intensity interval exercise on irisin level and body fat percentage in overweight sedentary women. Subjects were divided into 2 groups, the experimental (EXP) group (n = 10) and the control (CON) group (n = 10). The EXP group was using an ergo cycle of 10 sets, consisting of 60 s at 80-90% HRmax (cycling ∼120 rpm) and 60 s of active resting (cycling ∼40 rpm), intermittently. Blood serum and body fat percentage were measured before treatment and after 60 min of treatment. The results showed the serum irisin level was insignificant differences between EXP and CON groups. However, there was a significant decrease of irisin level between pre- and post-data in both EXP and CON, and the significant decrease of it between pre and post was in control group (EXP 6.65 ± 0.767 vs 5.76 ± 0.825, ; CON 7.46 ± 1.659 vs 5.80 ± 0.935 ng/ml, ). The change in body fat percentage was significant lower in EXP compared to CON (0.30 ± 0.217; 0.23 ± 0.118%; ). The conclusion is that the acute effect of HIIE can maintain the irisin level, and may also maintain the burning of body fat, which will lead to the reduction of body fat.

This article discusses the relationship of Sibylla Schwarz’ poem Verachtung der Welt and its Dutch source: passages from Jacob Cats’ book Houwelyck (1625), a kind of guide to marriage for the Dutch bourgeoisie. Previous research was not able to identify this source, partly because Schwarz takes a very unique approach with her adaptation. A comparative analysis of the texts brings Schwarz’ translation strategies into the foreground, which in turn demands a reevaluation of conclusions and assumptions about her work that until now have gone mostly unquestioned. The comparative analysis also reveals how skillfully Schwarz was able to make use of the Early Modern ‘spaces’ of translation, as she inscribes a new poetic dimension into Cats’ text.

Published: February 2024

During grass surveys across the islands of Hawai‘i in 2022, two novel hybrids among non-native Poaceae were found growing on roadsides. Spontaneous hybridization was observed among Chloris barbata and C. divaricata on O‘ahu and among Cenchrus clandestinus and C. setaceus on Hawai‘i island. Morphological evidence initially suggested these plants may be hybrids and molecular analysis using the ITS and rpl32-trnL regions confirmed that the plants are hybrids and identified their parentage. These hybrids are named Chloris × pseudosagrana nothosp. nov. and Cenchrus × peregrinus nothosp. nov. No developed seeds could be found on either of these hybrids and they are suspected to be sterile F1 hybrids. The occurrence of hybridization events among other non-native species are also discussed.
A fuzzy adaptive complementary filter for attitude estimation based on norm judgment
Authors: Jiang Pengcheng , Liu Chang , Cong Hua , Zhang Fuqiang
Published: February 2024

Unmanned aerial vehicle (UAV) has great application prospect because of its capability of three-dimensional space operation. The reliability of attitude and heading reference system (AHRS) for UAV attitude estimation is crucial for the application of UAV. When a UAV is subjected to unknown electromagnetic interference and force interference in flight, its attitude detection system can suffer from reduced accuracy or even failure. In this paper, a fuzzy adaptive complementary filter (CF) for attitude estimation based on norm judgment is proposed to solve the problem that the sensor is easily disturbed by the complex flight environment and the fixed filter parameters are difficult to obtain the UAV attitude accurately under different flight states. Firstly, the correction model of the gyroscope, which includes four filter parameters, namely accelerometer weight, magnetometer weight, proportional gain P and integral gain I, is established. Secondly, the influence of the four parameters on the estimation accuracy is analyzed. Finally, the adaptive adjustment rules are designed to adjust the filter parameters online and thus achieve the accurate and reliable measurement of UAV attitude. The feasibility of the proposed algorithm is verified through static, dynamic and interference experiments with the specially designed AHRS test platform. And the results show that the attitude estimation algorithm designed in this paper can ensure the high accuracy of the system in both steady state and high-speed rotation, shield the pitch and roll angles from the acceleration of motion, and keep the yaw angle from the external magnetic field.
Gearbox fault diagnosis method based on improved semi-supervised MTDL and GAF
Authors: Zhao Peng , Pang Xinyu , Li Feng , Lu Kaibo , Hu Shouxin
Published: February 2024

Aiming at the problem that it takes a long time and high cost to obtain complete labeled data under intelligent fault diagnosis and unlabeled data is not used. This paper proposes an improved semi-supervised mean teacher deep learning (MTDL) and Gramian angle field (GAF) fusion diagnostic method. This method fully utilizes a small number of labeled samples and a large number of unlabeled samples to deeply mine invisible fault features and potential physical correlations. At the same time, it solves the problem of losing the inter-data correlation structure when one-dimensional time series signals are used as inputs for neural networks. The GAF-MTDL method uses consistency regularization and modifies the network structure in the mean teacher algorithm into a semi-supervised deep learning model enhanced by WideResNet. The experimental results show that the proposed GAF-MTDL method saves a lot of manual labeling costs, improves the recognition accuracy and generalization ability, and can achieve excellent prediction accuracy with very little labeled data. In the end, the accuracy of planetary gear fault identification reached 98.22% under the labeling rate of 20%, and the accuracy of fault identification reached 99.98% through the verification of the bearing data set of Case Western Reserve University. The value of this research is to bring an efficient and low-cost technology to the field of industrial intelligent fault diagnosis, which can significantly improve the accuracy of fault identification.
Investigation of seaming performance of dyed and finished polyester/viscose fabrics
Authors: Şevkan Macit Ayşe
Published: February 2024

Seaming performance of a fabric is an important property because seams on a garment play a major role in determining the quality of the garment. Seam efficiency is calculated by the ratio of seam strength to fabric tensile strength. Seam strength and fabric strength are affected by the fabric-related properties and the stitch-related parameters. Therefore, as well as the effects of seaming parameters, dyeing, finishing, and laundering processes that the fabric is exposed to before the seaming processes have an effect on the seam efficiency. Polyester/viscose blended fabrics, which are frequently preferred in textiles, are used in this study, and the effects of bleaching, dyeing, finishing, laundering, and seaming processes on seam strength and seam efficiency, fabric tensile strength and fabric tensile elongation, air permeability, and thickness properties of these fabrics are examined. After the processes, there will be an increase or decrease in the properties depending on which process is examined in detail. The results are evaluated statistically. According to the results obtained, it has been observed that the mentioned processes are effective on seam efficiency. It can be said that seam strength and seam efficiency values are affected by the processes in different ways, and also that seam parameters are effective on seam strength values. Different effects of fabric direction on tensile strength and seam strength values were also observed. As explained in the study, these processes affect the other features differently.
Platform urbanisation, infrastructures and techno-politics: The turn towards urban citizenship
Authors: Bignami Filippo , Hanakata Naomi Clara
Published: February 2024

This article analyses how digital platforms challenge and redefine the way in which urban forms of citizenship are shaped. What we call ‘platform urbanisation’ accelerated during the COVID-19 pandemic when digital platforms penetrated with increasing rapidity into every aspect of urban life. While these digital platforms have facilitated new possibilities for engagement, access to services, efficiency in processing data, and customising responses to people online and offline, they also pose political challenges related to inequality, privacy, exclusion and social polarisation. Developing a techno-political urban environment built upon inclusion, equality, and respect for the rights of users, necessitates leveraging the potential of digital platforms to empower citizens and acknowledging and incorporating the political nature of this new urban environment. Furthermore, the intersection between the political influence of platforms on the governance of citizens and everyday life has a biopolitical dimension, since the power of platforms is exercised through policies and practices that affect individuals and collectivities. The article clarifies two essential facets of platform urbanisation: (1) the political nature of such a process, which requires a reframing of citizenship and (2) the role of both material and immaterial infrastructures in this process, which serve thus to constitute it as a new biopolitical territory. This conceptual expansion allows us to interpret digital platforms as an inextricable merging of political rationality, administrative techniques and technology.
Taking the Pulse of Georgia Local Election Officials After Senate Bill 202
Authors: (Trey) Hood M. V. , McKee Seth C.
Published: February 2024

In the aftermath of Republicans’ stinging losses in 2020 and 2021, which contributed to relinquishing the presidency and U.S. Senate majority, respectively, Georgia’s GOP lawmakers passed comprehensive electoral reform in Senate Bill (SB) 202. In this Field Note, we outline SB 202’s major provisions, and then present results of a survey querying Georgia local election officials (LEOs) to assess how SB 202 affected administrative performance in the 2022 midterm elections. Unquestionably, SB 202’s raft of reforms greatly altered Georgia’s administrative apparatus, but it is anything but clear that these changes in the aggregate either improved or detracted from the system it replaced. Indeed, the most credible judgment rendered from LEOs, is that administrative performance is case-specific, and therefore highly contingent upon the reform of interest.

Authors: Wang Zhijun , Chen Lijia , Wu Bin , Chen Chongyang , Sun Benshuang , Meng Jiang , Liu Bingning , He Jilin
Published: February 2024

Herein, titanium or thin doped indium zinc oxide (IZO) ceramic targets, composed of TiO2/SnO2, In2O3 and ZnO were prepared. The preparation of composite powders, microstructure evolution, densification and photoelectric properties of these ceramic targets were systematically in detail. The results indicated that doping of SnO2 was more conducive to the density of IZO targets than the doping of TiO2, while they all were beneficial for optimizing electrical performance of IZO ceramic targets due to the solid solution of TiO2/SnO2 in phases, thus the doped IZO ceramic targets had lower resistivity than nondoped IZO targets. In addition, 1wt% SnO2 doped in IZO ceramic targets performed the best (relative density > 99%, resistivity < 1.1 mΩ·cm, average grain size < 2 µm).

Background:

Regular cannabis is known to impact higher-order cognitive processes such as attention, but far less is known regarding cognitive flexibility, a component of executive function. Moreover, whether such changes are related to aberrations in the neural oscillatory dynamics serving flexibility remains poorly understood.

Aims:

Quantify the neural oscillatory dynamics serving cognitive flexibility by having participants complete a task-switching paradigm during magnetoencephalography (MEG). Probe whole-brain maps to identify alterations in chronic cannabis users relative to nonusers and determine how these alterations relate to the degree of cannabis use involvement.

Methods:

In all, 25 chronic cannabis users and 30 demographically matched nonuser controls completed neuropsychological testing, an interview regarding their substance use, a urinalysis, and a task switch paradigm during MEG. Time-frequency windows of interest were identified using a data-driven statistical approach and these were imaged using a beamformer. Whole-brain neural switch cost maps were computed by subtracting the oscillatory maps of the no-switch condition from the switch condition per participant. These were examined for group differences.

Results:

Cannabis users had weaker theta switch cost responses in the dorsolateral and dorsomedial prefrontal cortices, while nonusers showed the typical pattern of greater recruitment during switch relative to no switch trials. In addition, theta activity in the dorsomedial prefrontal cortex was significantly correlated with cannabis use involvement.

Conclusions:

Cannabis users exhibited altered theta switch cost activity compared to nonusers in prefrontal cortical regions, which are critical for cognitive flexibility. This activity scaled with cannabis use involvement, indicating a link between cannabis use and aberrant oscillatory activity underlying cognitive flexibility.
A nomogram to predict the risk of surgery-related pressure ulcers in patients undergoing cardiovascular surgery
Authors: Wei Xin , Xu Xiaoqing , Chen Yuan
Published: February 2024

Objective

In this study, we aimed to establish a new nomogram score to predict the occurrence of surgery-related pressure ulcers (SRPU) in patients undergoing cardiovascular surgery.

Methods

We conducted a retrospective study among patients who underwent cardiovascular surgery between February 2016 and November 2020.

Results

We established a prediction model based on a logistic regression model and tested the calibration and discrimination. We included 1163 patients who had undergone cardiovascular surgery. We formulated the logistic regression model, with Logit(P) = −11.745 + 0.024 preoperative hemoglobin value + 0.118 serum sodium value − 0.014 prealbumin value − 0.213 intraoperative mean temperature − 0.058 minimum mean arterial pressure + 0.646 preoperative blood potassium value + 0.264 smoking frequency + 0.760 hypertension history + 0.536 age ≥70 years. In this model ,“+” indicates that the factor is positively related to the occurrence risk of SRPU and “−” indicates that the factor is negatively associated with SRPU risk. The predictive model and nomogram had good accuracy in estimating the risk of SRPU, with a C-index of 0.755 (95% confidence interval: 0.719–0.792).

Conclusions

The present model can be used to effectively screen patients with a high risk of SRPU to devise targeted nursing intervention strategies and ultimately reduce the incidence rate of SRPU.
The Effect of Peer Influence and Neighborhood Quality on Incarcerated Fathers’ Attachment

Commonly referred to as the “hidden victims” of incarceration, children with a parent who is intermittently or repeatedly incarcerated face various challenges that exacerbate behavioral and psychological development. Using a baseline adaptation of the Multi-site Family Study on Incarceration, Parenting and Partnering (MFS-IP), we sought to clarify how peer influence and neighborhood quality can predict the extent of an incarcerated father’s attachment to the focal child and partner. Results showed a negative association between negative peer influence and poor neighborhood quality. Conversely, incarcerated fathers’ relationship with their biological mother and fathers produced a significant positive association. These findings propose that risk and protective factors can directly influence attachment levels with the focal child, as suggested by Social Control Theory. This article provides a basis for a more comprehensive understanding of clinical support that can be offered to children and families who bear the systemic societal mechanisms of incarceration.

Breast cancer screening guidelines vary for women at intermediate risk (15%-20% lifetime risk) for developing breast cancer across jurisdictions. Currently available risk assessment models have differing strengths and weaknesses, creating difficulty and ambiguity in selecting the most appropriate model to utilize. Clarifying which model to utilize in individual circumstances may help determine the best screening guidelines to use for each individual.
Welfare Euroscepticism and socioeconomic status
Authors: Eick Gianna M
Published: February 2024

While the European Union (EU) increasingly strengthens its social integration, opposition towards this process can also be observed, here defined as ‘welfare Euroscepticism’. To better understand this newly defined policy paradigm, this article aims to explain longstanding cleavages in both social policy and EU research: socioeconomic status (SES) divides. Contrary to the literature on public support for European integration, this article argues that higher SES groups are more likely to be welfare Eurosceptics than lower SES groups. This argument and its underlying explanations are examined through a multilevel approach using European Social Survey data from 18 EU member states, using the example of a potential EU-wide minimum income scheme. First, the results demonstrate that welfare Euroscepticism is indeed more prevalent among higher SES groups than lower SES groups (measured through occupation, education, income, and employment). The results indicate robust self-interest patterns among higher SES groups that do not want to carry (perceived) financial burdens of EU social policies. The opinion patterns also emphasize the multidimensionality of attitudes towards EU policies since the SES cleavages can reverse, depending on the policy in focus. Overall, the results indicate much potential to mobilize the larger proportion of the public to support EU social policies, that is, lower SES groups. However, potential conflicts may arise when the EU expands on policies that their traditional supporters – higher SES groups – are more likely to oppose. The article also shows that welfare solidarity on the individual and the country level can mitigate such conflicts. This is because higher levels of welfare generosity and lower levels of welfare chauvinism on the individual and the country level are related to smaller SES cleavages.

Political representation, the environment, and Edmund Burke: A re-reading of the Western canon through the lens of multispecies justice
Authors: Rutledge-Prior Serrin , Handby Edmund
Published: February 2024

A major puzzle in contemporary political theory is how to extend notions of justice to the environment. With environmental entities unable to communicate in ways that are traditionally recognised within the political sphere, their interests have largely been recognised instrumentally: only important as they contribute to human interests. In response to the multispecies justice project's call to reimagine our concepts of justice to include other-than-human beings and entities, we offer a novel reading of Edmund Burke's account of political representation that, we argue, can be applied to the environment. Burke claimed that interests are ‘unattached’ to any actual class or group, and that it is the duty of the representative to represent these unattached interests. Beyond providing an original application of Burke's work, the paper offers an alternative to the ‘allure’ of authoritarian environmentalism, an alternative which conservative thinkers may use as an entryway into debates on environmental justice.

Published: February 2024

Introduction. The likelihood of developing a diabetic foot ulcer (DFU) during one's lifetime for individuals with diabetes mellitus is around 19% to 34%. Continuous and repetitive loading on soft tissues are the major causative factors for DFU. This paper introduces an air cell array insole designed for cyclically offloading pressure from plantar regions to reduce repetitive stress and loading on foot. Materials and Methods. The insole comprises an air cell array insole and a pneumatic control unit. The interface pressure was evaluated in static and dynamic conditions at 3 different air cell internal pressures (6.9, 10.3, and 13.8 kPa). Plantar interface pressure was measured using a commercial pressure system, and data were analyzed using paired t test. Average interface pressure and peak pressure (PP) were studied to evaluate the functionality and effectiveness of the insole. Results. The analysis of static pressure data revealed that cyclic offloading significantly ( p < .05) reduced PP in 4 tested cells corresponding to big toe, metatarsal heads, and heel areas with the maximum mean difference of 12.9 kPa observed in big toe region. Similarly, dynamic pressure data analysis showed that cyclic offloading significantly ( p < .05) reduced PP in these areas, with the highest mean PP reduction of 36.98 kPa in the big toe region. Discussion. Results show the insole's capability to reduce plantar pressure through cyclic offloading. Internal pressure of air cells significantly affects the overall pressure reduction and must be chosen based on the user's weight. Conclusion. Results confirm that the insole with offloading capabilities has the potential to reduce the risk of developing DFUs by alleviating the plantar stress during both static and dynamic conditions.
