Accommodating Machine Learning Algorithms in Professional Service Firms
Authors: Faulconbridge James R. , Sarwar Atif , Spring Martin
Published: April 2024

Machine learning algorithms, as one form of artificial intelligence, are significant for professional work because they create the possibility for some predictions, interpretations and judgements that inform decision-making to be made by algorithms. However, little is known about whether it is possible to transform professional work to incorporate machine learning while also addressing negative responses from professionals whose work is changed by inscrutable algorithms. Through original empirical analysis of the effects of machine learning algorithms on the work of accountants and lawyers, this paper identifies the role of accommodating machine learning algorithms in professional service firms. Accommodating machine learning algorithms involves strategic responses that both justify adoption in the context of the possibilities and new contributions of machine learning algorithms and respond to the algorithms’ limitations and opaque and inscrutable nature. The analysis advances understanding of the processes that enable or inhibit the cooperative adoption of artificial intelligence in professional service firms and develops insights relevant when examining the long-term impacts of machine learning algorithms as they become ever more sophisticated.
Three-year follow-up analysis of automated microfoam preparation system for great saphenous vein incompetence and varicose veins sclerotherapy treatment
Authors: Alongi Giovanni , Bissacco Daniele , Cervi Edoardo
Published: April 2024

Background

To describe the treatment of patients with great saphenous vein (GSV) incompetence and varicose veins (VVs), utilizing an Automated Microfoam Preparation System (AMPS, Varixio®, VB Devices, Barcelona, Spain).

Methods

Adults between January and June 2021 were included. The AMPS system was used for foam preparation. Sclerotherapy treatment followed international recommendations. The primary endpoint was GSV closure rate after 36 months.

Results

164 patients were enrolled. During the 7-day follow-up period, all GSVs showed complete closure, which was maintained at the 1-year mark. No major complications were reported. A cumulative complete GSV recanalization rate of 6.1% and a partial recanalization rate of 26.8% after 36 months were noted. Some patients (9.7%) required additional treatment. A higher BMI was associated with complete recanalization.

Conclusion

The AMPS offers an easy-to-use and standardized procedure, potentially enhancing treatment outcomes if compared with manual preparation. Caution is advised when treating obese patients.
A qualitative systematic review of trust in technology
Authors: Schuetz Sebastian , Kuai Le , Lacity Mary C. , Steelman Zach
Published: April 2024

Although many information systems (IS) scholars have researched the antecedents and consequences of trust in technology, the sheer amount of work published, authors’ use of inconsistent construct terms, and variations in conceptualization and measurement make it difficult to compare and aggregate findings across studies. To provide scholars with an overview of the literature, we performed a systematic qualitative review of the IS literature. The goal of our review was to identify the antecedents and consequences of trust in technology that have received frequent empirical support, as well as those for which the evidence is not yet conclusive. To that end, we curated a glossary of unique construct terms and summarized the results of 241 relationships tested in 62 empirical research articles (both quantitative and qualitative) from the AIS “Basket of Eight” journals. From these, we identified 62 unique relationships: 22 are well-supported, 6 are supported by suggestive evidence, and 34 have received little support. These relationships summarize what is well-known and less well-known within the literature. By taking stock, we prepare a path for future research on the phenomenon of trust in the context of emerging technologies (e.g., artificial intelligence and blockchain). We conclude the paper with opportunities and directions for future research.

Authors: Menzella Francesco , Munari Sara , Corsi Lorenzo , Tonin Silvia , Cestaro Walter , Ballarin Andrea , Floriani Ariel , Dartora Cristina , Senna Gianenrico
Published: April 2024

Asthma is a disease characterised by heterogeneous and multifaceted airway inflammation. Despite the availability of effective treatments, a substantial percentage of patients with the type 2 (T2)-high, but mainly the T2-low, phenotype complain of persistent symptoms, airflow limitation, and poor response to treatments. Currently available biologicals target T2 cytokines, but no monoclonal antibodies or other specific therapeutic options are available for non-T2 asthma. However, targeted therapy against alarmins is radically changing this perspective. The development of alarmin-targeted therapies, of which tezepelumab (TZP) is the first example, may offer broad action on inflammatory pathways as well as an enhanced therapeutic effect on epithelial dysfunction. In this regard, TZP demonstrated positive results not only in patients with severe T2 asthma but also those with non-allergic, non-eosinophilic disease. Therefore, it is necessary to identify clinical features of patients who can benefit from an upstream targeted therapy such as anti-thymic stromal lymphopoietin. The aims of this narrative review are to understand the role of alarmins in asthma pathogenesis and epithelial dysfunction, examine the rationale underlying the indication of TZP treatment in severe asthma, summarise the results of clinical studies, and recognise the specific characteristics of patients potentially eligible for TZP treatment.
Iran’s water policy: Environmental injustice and peripheral marginalisation
Authors: Hassaniyan Allan
Published: April 2024

Water exhibits various politico-economic dynamic. Water scarcity can lead to conflicts, and it lies at the core of Iran’s environmental crises. The literature on Iran’s water crisis indicates the effects of this issue in terms of multidimensional environmental degradation, community disintegration, and state-society and intercommunal conflict. Approximately 28 million of Iran’s 85 million residents reside in water-stressed areas, a situation identified as ‘water bankruptcy’. The water shortage is experienced differently across the country. The plateau’s central regions, home to Iran’s major industries, are where the worst water deficit is occurring. However, regions with abundant water resources have also been impacted. These regions – known as ‘donor basins’ – due to intensive and disproportional inter-basin water transfer and other engineering interventions deployed by the Government to deal with the water shortage of the central regions, suffer from a different form of water crisis. A condition of asymmetrical and conflictual power relations between the state and subaltern communities in Iran’s peripheral regions has been created. This paper argues that this constitutes environmental racism, characterised by multilayered impoverishment and unsustainable development among communities in the donor regions.
CLOCK gene circannual expression in cluster headache
Authors: Oliveira Renato , Neves-Costa Ana , Pedroso Dora , Paixão Tiago , Barros André B. , Moita Luís F. , Gil-Gouveia Raquel
Published: April 2024

Background

Cluster headache is a primary headache disorder characterized by bouts with circadian and circannual patterns. The CLOCK gene has a central role in regulating circadian rhythms. Here, we investigate the circannual CLOCK expression in a population of cluster headache patients in comparison to matched controls.

Methods

Patients with cluster headache were sampled two to four times over at least one year, both in or outside bouts, one week after each solstice and equinox. The expression of CLOCK was measured by quantitative real-time polymerase chain reaction (RT-PCR) in the peripheral blood.

Results

This study included 50 patients and 58 matched controls. Among the patient population, composed of 42/50 males (84%) with an average age of 44.6 years, 45/50 (90%) suffered from episodic cluster headache. Two to four samples were collected from each patient adding up to 161 samples, 36 (22.3%) of which were collected within a bout. CLOCK expression for cluster headache patients was considerably different from that of the control population in winter (p-value mean = 0.006283), spring (p-value mean = 0.000006) and summer (p-value mean = 0.000064), but not in autumn (p-value mean = 0.262272). For each season transition, the variations in CLOCK expression were more pronounced in the control group than in the cluster headache population. No statistically significant differences were found between bout and non-bout samples. No individual factors (age, sex, circadian chronotype, smoking and coffee habits or history of migraine) were related to CLOCK expression.

Conclusions

We observed that CLOCK expression in cluster headache patients fluctuates less throughout the year than in the control population. Bout activity and lifestyle factors do not seem to influence CLOCK expression.
Progress in adhesive-bonded composite joints: A comprehensive review
Authors: Karthikeyan N. , Naveen Jesuarockiam
Published: April 2024

Among the myriad joining techniques, the adhesive bonding technique is widely used to join complex large-scale composite structures because of its numerous advantages compared to traditional joining techniques. This article profusely analysed the various techniques for ameliorating the performance of composite joints, such as bonding methods (secondary bonding, co-bonding, co-curing, and multi-material bonding), surface modification techniques (plasma, laser surface treatment, surface grinding, etc.), additional reinforcement techniques (Z pin, wire mesh, nanofiller, etc), and different joint geometries (stepped joints, half-stepped joints, balanced joints, and scarf joints). Also, the effect of various adhesives and fabrication techniques on the static and dynamic performance of CFRP and GFRP-based joints was studied in detail. Moreover, this review addresses the finite element modelling and optimisation techniques on adhesively bonded joints. It has been observed that the bonding methods, surface modification to enhance the roughness of the adherend, addition of nanofillers, and variations in joint geometry greatly influence the shear strength, fracture toughness, fatigue, and vibration behaviour of FRP composite joints.
The Purpose of Internet Use and Face-To-Face Communication With Friends and Acquaintances Among Older Adults: A JAGES Longitudinal Study
Authors: Chishima Iwao , Nakagomi Atsushi , Ide Kazushige , Shioya Ryunosuke , Saito Masashige , Kondo Katsunori
Published: April 2024

Internet use influences social interactions in society. However, there is no consensus on whether and what kind of Internet use increases face-to-face communication (FFC). This study investigated the mode of Internet use that increases FFC among older adults after three years. Participants were 8734 adults aged 65 or older who responded to the Japan Gerontological Evaluation Study (JAGES) surveys in 2016 and 2019. The exposures were the purposes of Internet use in 2016. The outcome was the frequency of FFC with friends or acquaintances in 2019. The confounders included 13 demographic, socioeconomic, and psychological variables. We performed modified Poisson regression analyses and found that Internet use for communication in 2016 increased FFC in 2019, especially for low-frequency FFC in 2016. Internet-based non-FFC may help promote FFC and prevent social isolation among older adults who are less likely to interact with others.
The Role of Late-Life Work Among Widowed Adults in Korea: A Buffer or Burden for Widow(er)s’ Health?
Authors: Cho Hyeonji , Kim Nahyun , Kim Kyungmin
Published: April 2024

To examine the role of work in the bereavement process, we focused on health changes among widowed adults. We analyzed a sample of 518 adults (aged 52–95) from the Korean Retirement and Income Study (2011–2019) who experienced spousal loss during the study period. The widowed participants provided data on their employment status and perceived health at both pre-loss and post-loss. Widowed participants reported worse physical and mental health after the bereavement, but the significant health deterioration was not observed among employed participants. Adjusting for pre-loss health status and other covariates, employed widow(er)s showed a smaller decrease in physical and mental health, compared to their counterparts. The effect of employment on physical health changes was more pronounced for economically vulnerable widow(er)s. Work might serve as a restoring coping strategy for widowed individuals; economic benefits from the job may also contribute to their health and well-being.

Authors: Daikeler Jessica , Fröhling Leon , Sen Indira , Birkenmaier Lukas , Gummer Tobias , Schwalbach Jan , Silber Henning , Weiß Bernd , Weller Katrin , Lechner Clemens
Published: April 2024

While survey data has long been the focus of quantitative social science analyses, observational and content data, although long-established, are gaining renewed attention; especially when this type of data is obtained by and for observing digital content and behavior. Today, digital technologies allow social scientists to track “everyday behavior” and to extract opinions from public discussions on online platforms. These new types of digital traces of human behavior, together with computational methods for analyzing them, have opened new avenues for analyzing, understanding, and addressing social science research questions. However, even the most innovative and extensive amounts of data are hollow if they are not of high quality. But what does data quality mean for modern social science data? To investigate this rather abstract question the present study focuses on four objectives. First, we provide researchers with a decision tree to identify appropriate data quality frameworks for a given use case. Second, we determine which data types and quality dimensions are already addressed in the existing frameworks. Third, we identify gaps with respect to different data types and data quality dimensions within the existing frameworks which need to be filled. And fourth, we provide a detailed literature overview for the intrinsic and extrinsic perspectives on data quality. By conducting a systematic literature review based on text mining methods, we identified and reviewed 58 data quality frameworks. In our decision tree, the three categories, namely, data type, the perspective it takes, and its level of granularity, help researchers to find appropriate data quality frameworks. We, furthermore, discovered gaps in the available frameworks with respect to visual and especially linked data and point out in our review that even famous frameworks might miss important aspects. The article ends with a critical discussion of the current state of the literature and potential future research avenues.
Finding modernity in England's past: Social anthropology and the remaking of social history in Britain, 1959–77
Authors: Foks Freddy
Published: April 2024

British historians drew on anthropological exemplars to remake social history between 1959 and 1977. Eric Hobsbawm's ‘primitive rebels’, Peter Laslett's World We Have Lost, Keith Thomas’s studies of witchcraft, and E. P. Thompson's ‘moral economy’ were all inspired by contemporary social anthropology, and they transformed historians’ understanding of the past. Reconstructing this moment of cross-disciplinary research contributes to our understanding of broader changes in the mid-century human sciences. This was a moment of grand theorizing about ‘modernization’, capitalism, and industrialization. Social historians responded to these concerns by drawing analogies between the past and the ethnographic present. The result was a number of hugely influential studies of social change that posed new questions to those seeking to create abstract models of modernization out of the English past.
Experimental study on abrasive flow finishing of narrow inner cavity of alumina-dispersed copper absorber

Published: April 2024

Given the difficulties in processing and detecting the narrow and deep inner cavities of the diffusive copper absorber used by the High Energy Photon Source (HEPS), a regression equation prediction model for surface roughness and material removal depth based on abrasive flow machining was proposed through mixed-level orthogonal experiments. The influences of machining area pressure, machining cycle number, and abrasive mesh number on surface roughness and material removal were revealed. Subsequently, abrasive flow machining verification experiments were conducted on the narrow and deep inner cavities of the absorber, showing that the experimental results were within 15% error compared to the model predictions. After abrasive flow machining, the roughness decreased from about 4.4 μm to around 0.6 μm, significantly improving the surface quality of the workpiece. These research findings can provide a theoretical basis and technical support for the optical finishing of workpieces with narrow and deep variable cross-section inner cavities.
Bayesian analysis of joint quantile regression for multi-response longitudinal data with application to primary biliary cirrhosis sequential cohort study
Authors: Tian Yu-Zhu , Tang Man-Lai , Wong Catherine , Tian Mao-Zai
Published: April 2024

This article proposes a Bayesian approach for jointly estimating marginal conditional quantiles of multi-response longitudinal data with multivariate mixed effects model. The multivariate asymmetric Laplace distribution is employed to construct the working likelihood of the considered model. Penalization priors on regression parameters are incorporated into the working likelihood to conduct Bayesian high-dimensional inference. Markov chain Monte Carlo algorithm is used to obtain the fully conditional posterior distributions of all parameters and latent variables. Monte Carlo simulations are conducted to evaluate the sample performance of the proposed joint quantile regression approach. Finally, we analyze a longitudinal medical dataset of the primary biliary cirrhosis sequential cohort study to illustrate the real application of the proposed modeling method.
“We Wanted to Get Her Help”: Child-Welfare-Involved Caregivers’ Perceptions of Decision-Making When Accessing Residential Treatment
Authors: McCarthy Lauren Pryce
Published: April 2024

Despite increased research and policy interest in reducing the use of residential treatment settings (RTS), there have been few studies of caregivers’ experiences accessing these settings. This study aimed to explore how caregivers perceive their role in decision-making when accessing RTS for youth using interpretive phenomenological analysis. Themes included gaining a voice, losing power as services intensified, challenging journey, and inflection point. Findings suggest providers act as gateways to RTS for youth for those parents who currently do not have access to these settings. Implications for practice include increasing caregiver knowledge about how to navigate mental health service systems may improve their sense of empowerment to make decisions and that more resources are needed for caregivers.
Posterior Positioning of Levator Veli Palatini with Intact Nasal Layer and Side-by-Side Bilateral Buccinator Flaps: Modified Approach for Palatal Lengthening
Authors: Hoghoughi Mohammad Ali , Kamran Hooman , Shahriarirad Reza , Salimi Maryam , Hosseinpour Hamidreza
Published: April 2024

Objective

To introduce a modified surgical method using bilateral buccinator flaps with posterior positioning of levator veli palatini muscles to treat velopharyngeal insufficiency.

Design

Cross-sectional clinical study

Patients

Non-syndromic patients with velopharyngeal insufficiency

Intervention

We performed a modified surgical method using posterior positioning of levator veli palatini muscles and side-by-side bilateral buccinator flaps.

Main outcome measures

Patients’ characteristics, severity of hypernasality, palatal lengthening size, and operative complications were recorded and described. The severity of hypernasality was determined by a speech therapist before and after the operation.

Results

A total of 26 non-syndromic patients, with a median age of 8.5 years, were enrolled. All patients presented with severe hypernasality. Following the operation and during the follow-up period, 12 patients showed a complete resolution of hypernasality, while 9, 3, and 2 patients exhibited mild, moderate, and severe hypernasality, respectively. In addition, the mean palatal lengthening was measured to be 25.3 ± 3.5 mm. Overall, three patients experienced partial flap loss in one flap, which was successfully repaired with a secondary intention without the development of a fistula. In five cases, complete closure of the donor sites couldn’t be achieved and thus were treated with secondary intention. Additionally, postoperative food restrictions were observed in seven cases but were resolved within one month. No other complications were noted in the remaining patients.

Conclusion

This modified palatal lengthening technique results in a significant lengthening of the palate while maintaining favorable speech outcomes. Future randomized clinical trials are warranted to validate our findings.
A framework for visual-based adaptive object-robot interaction of a mobile service robot
Authors: Soisudarat Puchong , Tothong Tanyatep , Tiraborisute Kawee , Dilokthanakul Nat , Manoonpong Poramate
Published: April 2024

The COVID-19 pandemic (hereinafter “the pandemic”) necessitated social distancing measures and limited physical contact, prompting the exploration of alternative methods for tasks like object delivery. Mobile service robots emerged as a potential solution, offering a bridge between humans and various tasks. While existing techniques have been introduced to enable robots to deliver objects in an end-to-end manner, they come with limitations. Grippers, for instance, can deliver only one object per round, cabinet robots require manual speed tuning to keep the object in place, and object holders lack generalizability. Inspired by the idea of human nature to use a tray to deliver the object, we developed the Visual-Based Adaptive Interaction System (hereinafter “VAIS”), a novel learning system, to improve service delivery using visual information and a fast neural learning mechanism. Within this system, the robot learns the optimal angular rotational and linear translational moving speeds to effectively transport objects placed on a tray without an extra holder. The robot validates these learnt movements by successfully completing multiple-object delivery tasks along designated routes. The results exhibit that the robot can utilize online learning after a few attempts to determine its proper moving speed and deliver different objects to a given location.
High and Dry: Rental Markets After Flooding Disasters
Authors: Brennan Mark , Srini Tanaya , Steil Justin
Published: April 2024

Recent disasters across the United States highlight the devastating effect of climate-change on individuals and households. The effects of these disasters on access to housing and housing stability are pressing issues of social equity and urban policy. How, if at all, do disasters affect rents? We find that severe floods are associated with significant increases in rents for households renting units priced at the bottom of the rent distribution, but not the middle or the top. Second, is there a relationship between federal rental assistance to affected households and any price changes in the market? We find that disaster rental assistance is not associated with changes in rents after flooding disasters. These findings raise important questions about how policy should support low-income renters after disasters, including those not directly displaced by the disaster who are facing increased rents after a disaster but unable to access federal post-disaster rental assistance.
Connecting weakly nonlinear elasticity theories of isotropic hyperelastic materials
Authors: Du Yangkun , Hill Nicholas A , Luo Xiaoyu
Published: April 2024

Soft materials exhibit significant nonlinear geometric deformations and stress–strain relationships under external forces. This paper explores weakly nonlinear elasticity theories, including Landau’s and Murnaghan’s formulations, advancing understanding beyond linear elasticity. We establish connections between these methods and extend strain-energy functions to the third and fourth orders in power of [Formula: see text], where [Formula: see text] and [Formula: see text], and [Formula: see text] is the perturbation to the deformation gradient tensor [Formula: see text]. Furthermore, we address simplified strain-energy functions applicable to incompressible materials. Through this work, we contribute to a comprehensive understanding of nonlinear elasticity and its relationship to weakly nonlinear elasticity, facilitating the study of moderate deformations in soft material behavior and its practical applications.
Investigation of the effects of corn flour, Spirulina powder, and buffalo yogurt on the quality characteristics of gluten-free muffins
Authors: Erem Fundagül
Published: April 2024

This study aimed to investigate the properties of buckwheat flour-based gluten-free muffins formulated by using corn flour (CF), Spirulina powder (SP), and buffalo yogurt (BY) levels as the factors in the Box-Behnken experimental design. The color values, total soluble polyphenol content (TPC), radical scavenging activity (RSA), specific volume, moisture content, and baking loss results were evaluated as the response variables in the design. The buckwheat flour in the control sample was substituted with CF and SP. Cow yogurt was used in the control muffin instead of milk and was substituted with BY at different levels in other samples. Among the response variables, TPC and RSA values were selected for the optimization studies. Decreasing the CF and SP levels in the formulations resulted in observing higher TPC and RSA values. Three optimal formulations were obtained by response surface methodology. Both cow and buffalo yogurt did not change the properties of the muffins adversely compared to milk. Increasing the SP content made the muffins firmer and caused a decrease in the L*, a*, b*, and browning index values of the muffins. However, sensory scores of SP-containing muffins were also satisfactory.
Disrupting the Obligation of Objective Knowledge in Dance Science Research
Authors: Petts Louisa , McGill Ashley
Published: April 2024

Background:

Through pressure from funding and governing bodies, an audit culture invades the rhetoric of the dance medicine and science research community, leading to undue focus on justifying and legitimizing the holistic benefits of dancing. This paper critiques this hierarchical value system which disproportionately favors objective, generalizable, and quantitative research approaches still dominant in dance medicine and science, existing since the founding of the International Association for Dance Medicine and Science (IADMS) in 1990.

Purpose:

Whilst this may mean studies are generalizable when applied to broader contexts, objective outcomes lack granularity and do not automatically lead to appropriate, meaningful, inclusive, or accessible dance experiences for everyone. Subjective, idiographic, ethnographic, embodied, phenomenological, and transdisciplinary approaches to dance medicine and science research have great potential to broaden, deepen, and enrich the field.

Conclusions:

This paper highlights the tensions between qualitative and quantitative methodologies, advocating that researchers can rigorously embrace their positionality to contribute toward ontological and epistemological clarity with any researcher bias, assumption, or expectation transparently disclosed. The writing draws on research examples from Dance for Health (DfH) as a part of dance science and medicine field of study, including but not limited to Dance for Parkinson’s. This paper provides resourceful recommendations, encouraging researchers to remain imaginative and curious through application of arts-based, person-centered, collaborative mixed methods within their own studies.
Postcolonialism, culture, and values in evaluating scientific collaborations with minority-serving institutions
Authors: Stone Courtney , Albrechtsen Caitlin J. , Boyce Ayesha S.
Published: April 2024

Postcolonial theory can be paired with a values-engaged educative evaluation approach to resist imperialism and colonialism in evaluation spaces, de-Westernize conceptualizations of diversity, equity, and inclusion, and extend the capacity of culturally responsive evaluation. Beyond the joining of the values-engaged educative approach and postcolonial theory, Collaboration Research Network theories offer another distinct but complementary avenue for exploring structural power imbalance and invisible hierarchies in science, technology, engineering, and mathematics evaluation contexts. Using these three theories, values-engaged educative, Collaboration Research Network, and postcolonial theory, this qualitative study examined the perceptions and experiences of faculty and students at three minority-serving institutions participating in a science, technology, engineering, and mathematics Center. This study aims to bridge theories traditionally used in research with evaluation frameworks to reconceptualize concepts of diversity, equity, and inclusion.
A Narrative Review of LGBTQ+ Marketing Scholarship
Authors: Lewis Clifford , Mehmet Michael , Reynolds Nina
Published: April 2024

Marketing research on LGBTQ+ people has increased over the past two decades, entering mainstream marketing discourse – aligning with greater societal acceptance. This paper provides a contemporary review of marketing scholarship on LGBTQ+ communities published in Q1, and Q2 ranked Scimago marketing journals. Taking a social justice lens, this review examined whose voices were represented and how those voices were represented. The finding suggests samples studied were skewed towards heterosexual samples and those from the Global North. Where LGBTQ+ samples have been included, these were predominantly gay men. Three theoretical perspectives were adopted: attitudes and identity, meaning and interpretation and critical perspectives. In addition, the focus of the studies centred on four main themes: LGBTQ+ imagery in advertising, consumer behaviour of LGBTQ+ people, brand positioning and LGBTQ+ as a consumer market segment. Based on the findings, future scholarship should consider nuancing the multidimensional nature of the LGBTQ+ markets and investigates LGBTQ+ consumers as individuals with real and unique needs in their own rights.

Published: April 2024

At present, most of the turbofan engine use the articulated link mount to connect the engine to the wing. The mechanical modeling, analysis and experimental research of articulated link mount are important means in the development of engine mount. In this paper, multibody dynamics method is used to establish the dynamic theory equation for a certain type of turbofan engine mount, and the low-frequency approximation method of the MNF file is proposed, which greatly improves the calculation speed on the basis of ensuring the calculation accuracy. In addition, a full-scale engine mounting system vibration isolation performance test platform was developed, and the vibration isolation efficiency of a certain type of engine mount at the high and low pressure rotor frequency was obtained. The results show that the simulation and test results agree well, the error is within 15% at the low-frequency, and 5% at the high-frequency. This work provides theoretical method and test evaluation means for the design and improvement of large passenger aircraft engine installation devices.
A green but also just transition? Variations in social and industrial policy responses to industrial decarbonisation in EU member states
Authors: Im Zhen Jie , de la Porte Caroline , Heins Elke , Prontera Andrea , Szelewa Dorota
Published: April 2024

The EU aims for net carbon neutrality by 2050. Since industry contributes substantially to carbon emissions, reforms to decarbonise industry are necessary to achieve this goal. However, these reforms may entail labour market costs in the form of unemployment, which may necessitate social policies to mitigate them. Our article provides a novel contribution to the existing literature by developing a framework to classify how these policy responses may vary across EU Member States and it also suggests sources for these variations. We analyse the planned social policy responses of four countries – Denmark, Germany, Spain and Poland – by comparing the emphasis on social investment relative to compensation; the emphasis on social relative to industrial policy; and the extent to which social policy is targeted. Our findings suggest that Danish plans will rely primarily on social investment, whereas Poland will rely on compensation. In Germany, there is a greater emphasis on industrial policy, and Spain’s planned responses differ between policies targeted at coal miners and policies for other workers.
Marcel Mauss, MAUSS and Maussology: The productive reception of the Essay on the Gift in France
Authors: Vandenberghe Frédéric
Published: April 2024

Alain Caillé, the founder of the Mouvement du MAUSS, presents an influential interpretation of Marcel Mauss’s classic Essay on the Gift as a foundational text of and for an anti-utilitarian theory of action. This article returns to Mauss’s seminal essay and presents the paradigm of the gift by resituating the MAUSSian reading within the French field of Maussology. While the article is largely sympathetic to the anti-utilitarian project, it also develops critiques and theoretical suggestions of its own.
Using organizational theory components to improve the structure of blended/flipped classes: Understanding the impact of design choices
Authors: Matherne Brett P , Roth Wendy Swenson
Published: April 2024

Technological advancements and market pressures are driving the development of pedagogical course design approaches. By using organizational design research into structuring organizations and work processes to improve effectiveness and efficiency, we focus on two structural constructs from organizational design research: standardization (of coordination including active learning components) and centralization (of decisions making for course implementation). This paper examines the impact of changes to these constructs during the conversion of a course from a traditional (face-to-face) to a blended/flipped modality. Findings show that structuring a course based on standardization and centralization can affect the student outcomes in the course. Specifically, revealing no statistical difference in short-term student performance from the traditional lecture approach to the blended/flipped approach; however, lower variability in performance occurred across sections. In addition, a lagged learning effect derived from an exit exam in students’ last semester, revealed a statistical difference with students from the blended/flipped approach achieving higher long-term learning scores. We offer this as an argument for the effectiveness of the standardized active learning components embedded within the new course structure.
Multi-bolt looseness positioning using multivariate recurrence analytic active sensing method and MHAMCNN model
Authors: Chen Yixuan , Zhu Lei , Gao Zhennan , Li Weijie , Wu Jianchao
Published: April 2024

The piezoelectric active sensing method has been proven to be an effective, nondestructive approach for bolt looseness monitoring. The conventional damage index relies on the energy index of the wavelet packet. However, the method of wavelet packet could not identify the looseness location of the multi-bolt. Therefore, an innovative multi-bolt intelligent method combined the multivariate recurrence analytic active sensing method with an improved convolutional neural network (CNN) model was proposed for multi-bolt looseness positioning. In this method, the multivariate recurrence plots (RPs) are firstly constructed based on the received stress waves and then it is utilized to extract the recursive attributes presented within the stress wave signals. Secondly, a novel model, the CNN improved by the multi-head attention mechanism (MHAMCNN), is constructed to extract nonlinear features hidden in multivariate RPs. Repeated experiments demonstrate that the proposed method, which combines MHAMCNN and un-thresholded multivariate RPs (i.e., mean detection accuracy: 98.62%), outperformed other methods, including multivariate RPs (i.e., mean detection accuracy: 97.06%) and common RPs. Compared with traditional pattern recognition algorithms, MHAMCNN has higher classification accuracy. In summary, the suggested approach presents a promising opportunity for the real-time monitoring of multi-bolt looseness.
Innovative welding integration of acousto-ultrasonic composite transducers onto thermoplastic composite structures
Authors: Galiana Shankar , Moradi Morteza , Wierach Peter , Zarouchas Dimitrios
Published: April 2024

Acousto-ultrasonic composite transducers (AUCTs), comprising piezoceramic materials in a reinforced polymeric matrix, show promise for structural health monitoring in composite structures. Challenges arise when integrating AUCTs onto highly loaded thermoplastic composites, especially low-surface-energy materials like polyaryletherketone composites. To address this, the study explores the viability of attaching AUCTs to low-melting polyaryletherketone carbon fiber-reinforced thermoplastic composite structures using ultrasonic welding. This welding technique forms a joint where the interface material fuses with the AUCT embedment and the structure matrix, providing a reliable and automatable process. The investigation includes a comparative analysis of an ultrasonic welded joint with an external energy director and a reference AUCT system integrated using a vacuum bagging oven procedure. Results highlight the potential of AUCT configurations integrated by ultrasonic welding as an alternative solution, acknowledging challenges that persist for further development and increased reliability in structural health monitoring applications.
To what extent do lay people and healthcare providers differ in the allocation of scarce medical resources in the context of the COVID-19 pandemic?
Authors: Campbell-Hewson Cristina , Grover Simmy , Furnham Adrian , McClelland Alastair
Published: April 2024

Studying the most ethical way to allocate scarce medical resources has been of interest within the last year, due to shortages associated with the COVID-19 pandemic. This study aimed to establish differences between what healthcare providers (HCP) and laypeople consider to be the most ethical way to prioritise the distribution of scarce resources. Healthcare providers ( n = 100) and laypeople ( n = 102) were asked to rank ethical principles from most to least ethical for the allocation of ICU beds in a COVID-19 outbreak, COVID-19 vaccinations and organ transplantation, and the rankings from each scenario across the two groups were compared. Results indicated that HCPs preferred utilitarian principles informed by medical knowledge, such as ‘prognosis’, whereas laypeople preferred less situation-specific and prioritarian principles, such as ‘sickest first’, replicating pre-pandemic findings. Laypeople showed increased in-group agreement when ranking principles, potentially due to the collective experience of the pandemic. Demographic variables such as older age, identifying as Black, Asian or minority ethnic and greater experience with COVID-19, were also associated with a preference for ‘prognosis’.
History and memory beyond classroom in Croatia
Authors: Blanuša Nebojša , Ljubojević Ana
Published: April 2024

This article examines attitudes of the Croatian final grade high school students towards the burdensome legacy of the Second World War and Croatian war for independence (1991–1995). Following the theoretical framework of memory studies, and implementing the concept of postmemory, we have developed a structural model connecting ideology and legacy of the wars. In addition, we have further modelled postmemory and its reliance on democratic values, namely political attitudes, trust in state institutions and political knowledge. Individualised predictors offered more nuanced analysis away from the binary understanding of pro-collaborationist and anti-fascist divide, in line with wider European trends and political culture(s).
A Review of Evidence-Based Dating Violence Prevention Programs With Behavioral Change Outcomes for Adolescents and Young Adults

Adolescent dating violence (DV) is not only a social but also a public health problem, necessitating the development and scale-up of prevention strategies. We conducted a review of the literature to identify adolescent and young adult DV prevention programs that have shown promising behavioral outcomes. The literature search covered articles published from 1996 to 2022 and indexed in Medline, Cochrane, Scopus, PsycINFO, and Embase. The review focused on programs implemented and evaluated in the United States or Canada that included intervention and comparison groups, a baseline assessment, and at least one post-assessment conducted after the intervention exposure. Promising behavioral outcomes were defined as positive, statistically significant differences between intervention and comparison groups with respect to DV perpetration or victimization or bystander behavior in relation to DV. A total of 118 articles were screened by abstract and read in-depth. Eighteen programs that met the inclusion criteria were identified. Of these programs, one showed reductions in DV victimization, six showed reductions in DV perpetration, and nine showed behavioral reductions in both violence perpetration and victimization. The review highlighted that while multiple programs have demonstrated efficacy in preventing or reducing intimate partner violence in North American youth populations, more robust research on the replication of these programs outside researcher-controlled environments is needed. Furthermore, issues with program inclusivity, such as with sex and gender-minority individuals, should be considered in future intervention development and replication research.
Enhancing bra design for post-mastectomy patients: Incorporating MRI data and innovative textiles for optimal support and comfort

Published: April 2024

This study introduces an innovative approach to designing a customized bra to the specific needs of mastectomy patients, aiming to reduce the discrepancies in breast displacement and consequently alleviate associated pain. Through mastectomy patient interviews, recognizing the limitations of current mastectomy bras, which often fail to accommodate the unique body shapes and needs of breast cancer survivors, this research leverages Magnetic Resonance Imaging (MRI) and Three-Dimensional Surface Imaging (3D-SI) to develop a custom-fit bra prototype. The methodology involves the analysis of body shape changes post-mastectomy and the development of a prototype bra that effectively supports prostheses while minimizing common issues such as displacement, discomfort, and skin irritation. The results showcased a pronounced reduction in breast movement in all directions with the prototype bra, further enhanced using a novel cooling textile, improving the wearer’s overall comfort. Moreover, our investigation delved into the potential of integrating MRI and 3D-SI anthropometric data in bra design. By comparing two Prototype bras with differing dimensions but identical design features, we discerned marked differences in their performance. Crucially, the Prototype bra, shaped predominantly using MRI data, reduced breast displacement and evaluated better fit compared to the bra using 3D-SI data. Results from the study indicate that the prototype significantly improves fit and wearer comfort, suggesting a promising direction for future development of mastectomy bras. The findings highlight the potential of utilizing medical imaging data in garment design to create more inclusive and considerate solutions for post-surgical care.

Background

The aim of this study is to determine how guidewire selection impacts procedure time and success and analyze if the trend toward the adoption of larger diameter guidewires provides a quantifiable advantage over traditional 0.014″ guidewires.

Methods

A review of 494 consecutively performed acute ischemic stroke cases performed between 2018 and 2022 were reviewed and grouped into cases using a single 0.014″ outer diameter (OD) guidewire (195 cases) and cases using a single 0.018″ or 0.024″ OD guidewire (128 cases). These groups were compared for differences in average time to recanalization, average number of passes to achieve recanalization, and first pass success. Cases were compared overall, and further analyzed by region of occlusion to look at specific guidewire related differences for cases with M1, M2, and ICA occlusions.

Results

Procedures using a larger OD guidewire have an average 5 min and 30 s reduction in time from puncture to recanalization (p = 0.0201). ICA occlusion cases using a larger macrowire show a 20 min reduction in recanalization time (p = 0.0005), a reduction in average number of passes from 2.6 to 1.7 (p = 0.0058), and an increase in first pass success from 18.8% to 58.3% when compared to traditional guidewires.

Conclusion

Large 0.018″ or 0.024″ OD guidewires better fill the lumen of the catheter and help to center the thrombectomy system in the vessel and navigate to the clot face. This leads to a reduction in procedure time and number of passes, and an increase in first pass success, especially when treating occlusions in the ICA.
