A new genus of the tribe Ephippigerini, Dinarippiger Skejo, Kasalo, Fontana et Tvrtković gen. nov., is described based on the characters of occiput coloration, tegmina coloration, cerci and pronotum shape. The new genus is morphologically intermediate between the genera Ephippiger Berthold, 1827 and Uromenus Bolívar, 1878, and presently includes only Dalmatian Saddle Bush Cricket, Dinarippiger discoidalis (Fieber, 1853) comb. nov., hitherto known as Ephippiger discoidalis Fieber, 1853. The species inhabits NE Italy (mainly Carso Triestino), SW Slovenia, Croatia, Bosnia & Herzegovina, and Montenegro, i.e., islands and karst habitats along the eastern Adriatic coast, with isolated findings in Albania and Italy. Its prominent variation in size and coloration has already produced many synonyms (= limbata Fischer, 1853, = limbata var. major Krauss, 1879, = limbata var. minor Krauss, 1879, = selenophora Fieber, 1853, = sphacophila Krauss, 1879), which may suggest that what is currently regarded as a single species could represent a complex of distinct species with restricted distributions. This study also presents an annotated distribution map and a bioacoustic analysis of D. discoidalis comb. nov. Further research, especially adopting molecular methods, is necessary to assess possible cryptic diversity within the genus Dinarippiger gen. nov. and elucidate its evolutionary history.
A conspicuously coloured new species of the Alpheus macrocheles group from the central Indian Ocean (Decapoda: Alpheidae)
Authors: ANKER ARTHUR
Published: April 2023

A new snapping shrimp species of the Alpheus macrocheles (Hailstone, 1835) group is described based on a single adult male specimen collected on an exposed forereef near Magoodhoo Island, Faafu Atoll, Maldives. Alpheus dingabadi sp. nov. is one of several species of the A. macrocheles group characterised by the presence of a stout distoventral tooth on the merus of the third pereiopod, but can be separated from all of them by several morphological features, including the unusually long appendix masculina on the second pleopod, as well as by its conspicuous and highly diagnostic colour pattern.

Impact of ENSO on Wintertime Land Surface Variables in Northern Hemisphere Extratropics: Role of Atmospheric Moisture Processes
Authors: Sun Linyuan , Yang Xiu-Qun , Tao Lingfeng
Published: April 2023

El Niño–Southern Oscillation (ENSO) is the strongest interannual signature in the tropical air–sea system and can affect global atmospheric variables, but ENSO’s climatic impact on land surface variables such as skin temperature, snow cover, and soil moisture that can serve as seasonal climate predictors remains relatively little known. Here we examine ENSO’s impact on the three land surface variables in Northern Hemisphere extratropics by regression analysis, using a combination of ERA5 reanalysis, GLDAS, satellite-based observations, and CESM2 simulations. Our results show that during El Niño winters anomalous land surface warming occurs in Northern Hemisphere midlatitudes, accompanied by snow cover reduction, especially in northern North America and eastern Europe, while anomalous cooling occurs in southern North America and the Tibetan Plateau, accompanied by increased snow cover. Meanwhile, increased soil moisture is observed in southern North America, central Asia, and southeast China. Further analysis indicates that atmospheric moisture processes dominate the formation of the land surface anomalies, for which the changes in water vapor and precipitation induced by the ENSO-related large-scale atmospheric teleconnection are critical. The anomalous land surface warming in midlatitudes mainly results from the increased downward longwave radiation due to the increase of water vapor, whereas the physical pathway causing water vapor anomalies is different over North America and Eurasia. Controlled by ENSO-induced changes in atmospheric circulation and moisture transport, anomalous precipitation explains most of the snow cover and soil moisture anomalies, which play a certain role in shaping the skin temperature anomalies in some regions through snow–albedo feedback and evaporation, respectively.
Perceived stress, anxiety and depression : Living along the border in Jammu and Kashmir
Authors: Pandey Shreyashee , Saxena Sakshi , Joshi Pooran C , Mahajan Chakraverti
Published: April 2023

Background:

Conflicts adversely affect psychological well-being and are associated with mental disorders.

Aim:

The study aims to assess the levels of perceived stress, anxiety and depression and their association with demographic factors among the youth in the border villages of Jammu and Kashmir (J&K).

Methods:

A cross-sectional study was conducted among youth aged 18 to 25 years. The sample consisted of 300 individuals from the border villages of J&K. Of these, 150 individuals were from the villages located near the International Border (IB) in the Jammu district, and 150 individuals were from the villages near the Line Of Control (LOC) in the Rajouri district. Perceived Stress scale (PSS), Generalised Anxiety Disorder (GAD7), and Public Health Questionnaire (PHQ9) scales were used to determine the levels of perceived stress, depression, and anxiety. Mann Whitney, Chi-square and Odds ratio analysis were performed to assess the levels of the indicators and their association with demographic factors.

Results:

94% of the respondents had perceived stress, 34.46% anxiety and 31% depression. Perceived stress, anxiety and depression were significantly higher among the LOC youth than IB youth ( p < .00*). The LOC youth with an educational status below graduation level were found to be more anxious ( p = .034) and more depressed ( p = .003) than those with the educational status of graduation and above. The youth whose main activity was that of a student were found to be more depressed than the employed and unemployed youth ( p = .000).

Conclusion:

Perceived stress, anxiety, and depression were prevalent among the youth in border villages. These were found to be significantly higher among youth in border villages on the LOC. The findings suggest that education level has a significant impact on the mental health of the youth.
Natural Experiments of the Rally 'Round the Flag Effects Using Worldwide Surveys
Authors: Seo TaeJun , Horiuchi Yusaku
Published: April 2023

The “rally 'round the flag” effect—a short-term boost in a political leader’s popularity during an interstate political dispute—was first proposed by Mueller (1970) more than half a century ago. However, there is no scholarly consensus on its empirical validity and the circumstances under which the effect becomes most prominent. In this paper, based on a natural experimental design, we analyze large-scale worldwide surveys of 34,118 responses and causally identify the effects of 46 militarized interstate disputes (MIDs) on the approval ratings of political leaders in 27 countries. We find that MIDs, on average, decrease public support for national leaders. However, the public backlash could be attenuated depending on theoretically relevant contexts. Our finding implies that political leaders cannot rely on MIDs for public support increases, as they are generally penalized for such decisions.
Bottom-up cluster branding through boundary spanners: The case of the Jingdezhen ceramics cluster in China
Authors: Wu Di , Coe Neil M.
Published: April 2023

It is increasingly recognised that for clusters to evolve and initiate new developmental paths, they need to bring in various external resources, especially external human capital. However, external talent often has imperfect knowledge regarding distant places; hence, a key challenge for clusters is to overcome this lack of knowledge and unfamiliarity to ensure that external talent becomes aware of the cluster’s local assets and the possibilities for (re)locating there. It is thus important for clusters to engage in cluster branding: that is, to promote its assets ‘outwards’ and to build-up a positive, renowned brand-name. While place branding is already an established theme in urban geography, cluster branding has hitherto been under-examined in the extant cluster literature in economic geography. Moreover, both the well-researched place-branding literature and the limited cluster-branding literature tend to be primarily concerned with official, top-down branding, initiated by government agencies. This article, instead, shows that branding can also involve organic, bottom-up processes driven by the agency of diverse individual actors, working in tandem with governmental actors. Through a case study of an arts and creative cluster, the Jingdezhen ceramics cluster in China, it unpacks how resourceful individual actors – conceptualised as boundary spanners – have become powerful agents in increasing the cluster’s legitimacy and visibility in the relevant industries through their personal networks and mobility, thereby contributing to attracting external talent into the cluster. More specifically, the study identifies three bottom-up cluster branding mechanisms, namely: convening temporary clusters locally; participating in external temporary clusters; and representing through digital media.
What if autonomous vehicles had been introduced into cities? A counterfactual analysis
Authors: Zhong Haotian , Li Wei
Published: April 2023

The impact of autonomous vehicles on the spatial size of cities remains ambiguous, as the future is highly uncertain. This paper uses counterfactual analysis techniques to examine the effects of autonomous vehicles on urban expansion for metropolitan areas in the United States if autonomous vehicles had been introduced before. We argue that distance cost and congestion cost, which are the two components of transportation cost with different effects on urban expansion, should be addressed in autonomous vehicle research. By coupling historical data with hypothetical scenarios of introducing autonomous vehicles to cities, we find that urban expansion, rather than urban densification, would have been the dominant effect if autonomous vehicles had been introduced into cities. The finding indicates that if autonomous vehicles are widely adopted in the future, they are likely to have similar, or even larger, effects on future urban expansion than in the counterfactual past.
Do Most Students Need in-Person Lectures? A Study of a Large Statistics Class
Authors: Fireman Ellen S. , Donnini Zachary S. , Weissman Michael B. , Eck Daniel J.
Published: April 2023

Over 1100 students over four semesters were given the option of taking an introductory undergraduate statistics class either by in-person attendance in lectures or by taking exactly the same class (same instructor, recorded lectures, homework, blind grading, website, etc.) without the in-person lectures. Roughly, equal numbers of students chose each option. The online students did slightly better on computer-graded exams. The causal effect of choosing only online lectures was estimated by adjusting for measured confounders using four standard methods. The four nearly identical point estimates remained positive but were small and not statistically significant at the 95% confidence level. Sensitivity analysis indicated that unmeasured confounding was unlikely to be large but might plausibly reduce the point estimate to zero. No statistically significant differences were found in preliminary comparisons of effects on females/males, U.S./non-U.S. citizens, freshmen/non-freshman, and lower-scoring/higher-scoring math ACT groups.
A Dynamic Perspective on Collaborative Innovation for Smart City Development: The role of uncertainty, governance, and institutional logics
Authors: Dolmans Sharon A. M. , van Galen Wouter P. L. , Walrave Bob , den Ouden Elke , Valkenburg Rianne , Romme A. Georges L.
Published: April 2023

Collaborative innovation is at the heart of smart city development, yet also notoriously challenging due to fundamental differences between public and private sector actors that need to collaborate, while dealing with high levels of uncertainty. Whereas existing practice-based work on collaborative innovation describes various relevant antecedents, barriers and success factors, this prior work potentially underestimates the true complexity of collaborative innovation initiatives. Therefore, scholars have increasingly called for a more dynamic, theoretical understanding of collaborative innovation. In response to these calls, our study draws on institutional theory to build a dynamic understanding of collaborative innovation for smart city development. Specifically, we conduct a longitudinal in-depth case study to develop a causal loop model, grounded in rich qualitative data, to capture and theorize the key behavioural patterns of a collaborative innovation initiative for smart city development. The model describes how the dynamic interplay between uncertainty, adherence to own institutional logics and governance complexity can both enable and undermine collaborative initiatives. We contribute by developing a dynamic theoretical perspective on collaborative innovation, one that promotes cross-fertilization at the intersection of the smart city theory, organization theory and collaborative innovation literature. Moreover, our findings highlight the important role of organization theory, specifically institutional logics, in explaining the collaborative dynamics of smart city development.
Digitalization, new business Startups, information and Communication Technologies and product innovation: Evidence From China in the lens of sustainability
Authors: Bai Jiawen , Bai Tianyu , Zhang Chengyun
Published: April 2023

The global economies and international organizations are inclined towards sustainable growth, technological advancements and product innovations. China is the leading economy in information and communication technologies and among the major industrially expanded economies covering a substantial share of the global market in exports. The prime objective of this study is to explore the role of digitalization and Information and communication technologies (ICT) for product innovation (PIN). In doing so, the study also attempts to draw some novel implications regarding business, entrepreneurship, and product innovation in the lens of sustainability. This current study use the annual data of China from 1990–2020. The empirical analysis was conducted using the stationarity testing and the Johansen cointegration test. In addition, due to the data’s asymmetrical distribution, the non-parametric “quantile regression” is used. For robustness, this study employs the Fully Modified Ordinary Least Square, Canonical Cointegration, and Dynamic Ordinary Least Square methods. The empirical results reveal that economic progress and financial development are substantial factors of product innovation. The robust analysis reveals that medium and high-tech industries and information and communication technology adversely affect product innovation. Further, the presence of financial development transforms the negative influence of information and communication technology into a positive. The current study concludes more investments in the technological industry are required to encourage product innovation in China. The study discusses some policy-related implications in the context of business sustainability and product innovation.

Published: April 2023

Practices that strengthen nurse work environments and enable them to have control over nursing practices have gained importance in recent years as they increase nurses’ retention and patient care quality. This study aimed to examine the relationships between structural empowerment and nurse and patient-reported outcomes and the mediating role of control over nursing practices in these relationships. This correlational and cross-sectional study was carried out from September 2018 to May 2019 at two public hospitals in Turkey. We recruited staff nurses ( n = 319) working in the inpatient units of these hospitals and their patients ( n = 319). Data were collected using self-report measures from staff nurses and patients. It was determined that structural empowerment and control over nursing practices had a positive relationship with job satisfaction and nursing care quality, as well as a negative relationship with intention to turnover; however, there was no relationship with patient-reported outcomes. Control over nursing practices partially mediated the relationship between structural empowerment and outcomes of job satisfaction and nursing care quality. This study indicates that promoting the structural empowerment of nurses and ensuring that they have control over practice will increase job satisfaction and quality of care. Nurse managers can increase nurses’ job satisfaction and quality of care by creating supportive work environments and ensuring they have control over nursing practices.

Published: April 2023

Background:

Although the infection rates for bone–patellar tendon–bone autograft (BTB), hamstring tendon autograft (HT), and allograft have been reported previously, there are limited data available for a large cohort of individuals undergoing anterior cruciate ligament (ACL) reconstruction (ACLR) using quadriceps tendon autograft (QT).

Purpose:

The aims of this study are (1) to compare rates of septic arthritis after primary and revision ACLR with QT, BTB, HT, and allograft and (2) to evaluate the association between an infection after ACLR and potential risk factors in a large single-system analysis.

Study Design:

Cohort study; Level of evidence, 3.

Methods:

All ACLR cases performed by 10 high-volume sports medicine fellowship–trained ACL surgeons between January 2000 and January 2022 were retrospectively analyzed. Minimum follow-up was 90 days after ACLR, and all multiligament reconstructions were excluded. Demographic information, surgical variables, infection characteristics, and rate of ACL graft retention were collected for all included patients. Independent samples t test, chi-square test, or Fisher exact tests with adjusted Benjamini-Hochberg post hoc procedure were used for group comparisons.

Results:

In total, 6652 patients were included in this study. The most commonly used graft was allograft (n = 2491; 37.4%), followed by HT (n = 1743; 26.2%), BTB (n = 1478; 22.2%), and QT (n = 940; 14.1%). The overall postoperative rate of septic arthritis was 0.34% (n = 23). Septic arthritis rates based on graft type were 0.74% (n = 13) for HT, 0.24% (n = 6) for allograft, 0.20% (n = 3) for BTB, and 0.10% (n = 1) for QT. While a statistically significant difference with regard to graft type ( P = .01) was observed, no significant relationships were found between postoperative septic arthritis and age, sex, revision ACLR, ACLR surgical technique, and accompanying intra-articular procedures for all septic arthritis patients ( P > .05). The average time from the onset of the symptoms of infection to surgical irrigation and debridement (I&D) was 2 days (minimum, 0; maximum, 6). ACL grafts were retained during I&D procedures in all patients with postoperative septic arthritis.

Conclusion:

The postoperative rate of septic arthritis was 0.1% after use of the QT autograft. While graft choice may affect rates of septic arthritis after ACLR, patient characteristics, ACLR technique, revision ACLR, and accompanying intra-articular procedures during ACLR were not associated with postoperative septic arthritis with the numbers available for analysis.
Autoclave process parameters affecting mechanical and thermomechanical properties of CFRP laminates using response surface methodology
Authors: Baghad Abd , El Mabrouk Khalil
Published: April 2023

Autoclave curing is a manufacturing process for high-performance parts based on carbon fiber–reinforced polymers (CFRPs) used for large aircraft parts. Today, this manufacturing process is the reference in terms of quality and, therefore, the manufactured parts’ mechanical performance and robustness. However, several parameters can impact the quality of the parts resulting from this process, which requires optimizing key manufacturing parameters. In this study, the effect of autoclave process parameters (i.e., temperature, pressure, and vacuum-pressure) on the glass transition temperature (Tg), laminate compressive modulus (LCM), laminate compressive strength (LCS), and interlaminar shear strength (ILSS) was investigated using three factors, three-level Box–Behnken design (BBD) and response surface methodology (RSM). In addition, the interactions of processing parameters with Tg, LCM, LCS, and ILSS were investigated, making this study an essential investigation for accurately selecting processing parameters. Thus, there is a functionally non-linear relationship between the interaction of the autoclave process parameters. Therefore, these parameters were optimized using RSM with the maximum Tg, LCM, LCS, and ILSS. The optimization and validation of the obtained models were carried out with an average relative error below 3% for all thermomechanical and mechanical properties, indicating that the BBD and optimization were correct. Because of this, the established regression models can accurately predict the Tg, LCM, LCS, and ILSS in autoclaved epoxy/carbon composite laminates.

Published: April 2023

Background:Vitamin B12 deficiency causes serious neurologic problems among infants. However, its neuroradiologic correlate is still largely obscure. Methodology: This prospective study was conducted on patients aged 6 months to 2 years. All children with proven vitamin B12 deficiency were planned to undergo magnetic resonance imaging (MRI) and magnetic resonance spectroscopy of the brain. Results: A total of 35 patients (63% female) were enrolled. Twenty-six (74%) patients had significant findings on brain MRI scan, commonest of which were thinning of corpus callosum and prominence of extra-axial spaces in 28.6% children, cerebral atrophy in 17%, and diffuse symmetrical hyperintensity of white matter in 5.7% patients. Using logistic regression, it was found that odds of abnormal neuroimaging findings were higher in children below 12 months, in females, and in patients with developmental regression, but none of them were statistically significant. Conclusion: Most of the infants with vitamin B12 deficiency have abnormal neuroimaging findings.
EU employment policy and social citizenship (2009–2022): an inclusive turn after the Social Pillar?
Authors: Huguenot-Noël Robin , Corti Francesco
Published: April 2023

When does the EU employment growth agenda also serve social progress? Scholars concerned with the equality/efficiency trade-off generally look at the EU as an agenda-setter. Little attention has yet been paid to its role as direct provider of social rights. Building on a data set of 71 EU measures and 317 judgments of the Court of Justice of the EU, this article evaluates the extent to which EU employment policies helped to advance social citizenship by assessing the scope and distribution of individual entitlements over time (2009–2022). Our findings show that, after almost two decades of silence, the EU not only expanded the scope of its influence over individual social rights but also took an inclusive turn, driven by more ‘universalising’ and ‘capacitating’ initiatives. Looking ahead, better monitoring of the distributive profile of EU initiatives indirectly affecting rights production (such as SURE or the Recovery and Resilience Facility) would help to ensure that this shift increasingly benefits those needing it the most.
Metamaterial beam with dual-action absorbers for tunable and multi-band vibration absorption
Authors: Althamer Saeed
Published: April 2023

This paper presents a new class of metamaterial beams of tunable and multi-band vibration absorption. The metamaterial beam is composed of uniform and periodic beam cells with locally resonant substructure called dual-action vibration absorber, DA. A DA vibration absorber comprising of three locally resonant subsystems, 3-DOF spring-mass-damper subsystems, is utilized to generate frequency stopbands to stop elastic wave propagation. The governing equations of motion for a periodic beam cell are derived. Several distinct mass and stiffness configurations for the metamaterial beam with DA vibration absorber are proposed. The dispersion relations and presence of three frequency stopbands are studied. A finite element method based on Timoshenko beam theory is used to model and analyze the introduced metamaterial beam with DA vibration absorber. The frequency response simulations agree well with the projected stopbands of the developed dispersion relations of the mass and stiffness configurations. The concept of the presented metamaterial beam with tunable and multi-stopbands is promising for wave propagation attenuation and control applications.
Aggressive Lymphoplasmacytic Neoplasm With an Unusual In-frame Deletion of MYD88 Associated With TRAF3 and TP53 Mutations and Complex Karyotype

Published: April 2023

Lymphoplasmacytic lymphoma often needs to be differentiated from other B-cell lymphomas with plasmacytic differentiation, especially marginal zone cell lymphoma. Molecular detection of MYD88 p.L265P hotspot mutation supports the diagnosis of lymphoplasmacytic lymphoma since it is seen in about 90% of such lymphoma, which is much higher than other B-cell lymphomas. MYD88 p.L265P is a gain-of-function mutation that enhances the activity of the NF-κB signaling pathway and therefore drives lymphomagenesis. Other mutations in MYD88 are rarely reported. This study aims to report an unusual MYD88 in-frame deletion in an aggressive lymphoplasmacytic neoplasm. This is an IgM-positive, CD5- and CD10-negative mature B-cell lymphoma with prominent plasmacytic differentiation and aggressive features. The clinical and pathologic findings were most consistent with lymphoplasmacytic lymphoma. Next-generation sequencing identified an unusual MYD88 in-frame deletion in the absence of the hotpot p.L265P mutation. Other concurrent pathogenic mutations also include truncating mutations of TRAF3, which is a negative regulator of the NF-κB signaling pathway, and a missense mutation of TP53. Karyotype analysis showed complex karyotypes, including chromosome 6q deletion. By searching literature and online cancer databases, we identified only 8 other mature B-cell lymphomas with MYD88 in-frame deletions, but none of them was diagnosed with lymphoplasmacytic lymphoma. Recognizing such in-frame deletions is necessary to help understand the mutational spectrum of MYD88 in B-cell lymphomas. It remains to be further investigated whether such MYD88 in-frame deletions are also overrepresented in lymphoplasmacytic lymphoma among other B-cell lymphomas.

Published: April 2023

It is important to understand how the composition and structure of proteins from other flours differ from proteins in wheat, in order to have a better option to substitute gluten products with gluten-free food products. The aim of this study was the characterization of gluten-free flours and comparison of their rheological and calorimetric properties against wheat flour, for its use as gluten-free alternative. Chemical composition analysis, water solubility index (WSI), water absorption index (WAI), texture and calorimetric profile were determined. The closest WAI to wheat flour (1.45 g gel/g sample) was corn flour (2.41 g gel/g sample), while the WSI of chickpea flour was 5.51% approaching that of wheat flour of 5.88%. The hardness and adhesiveness values closest to wheat (1.65 kgf and 0.03 mJ) were amaranth flour with 0.85 kgf and 0.01 mJ, respectively. The phenolic content and antioxidant capacity were higher in the corn and bean flours with 244.4 mg GAE/100 g, 148 mg GAE/100 g and 190 mg AAE/100 g and 170 mg AAE/100 g, respectively. The combination of these non-conventional flours can be an innovative source of gluten-free formulas.

Published: April 2023

Autosomal dominant hyper-IgE syndrome (AD-HIES) is linked to dominant negative mutations of the STAT3 protein whose molecular basis for dysfunction is unclear and presenting with a variety of clinical manifestations with only supportive treatment. To establish the relationship between the impact of STAT3 mutations in different domains and the severity of the clinical manifestations, 105 STAT3 mutations were analyzed for their impact on protein stability, flexibility, function, and binding affinity using in Silico approaches. Our results showed that 73% of the studied mutations have an impact on the physicochemical properties of the protein, altering the stability, flexibility and function to varying degrees. In particular, mutations affecting the DNA binding domain (DBD) and the Src Homology 2 (SH2) have a significant impact on the protein structure and disrupt its interaction either with DNA or other STAT3 to form a heterodomain complex, leading to severe clinical phenotypes. Collectively, this study suggests that there is a close relationship between the domain involving the mutation, the degree of variation in the properties of the protein and the degree of loss of function ranging from partial loss to complete loss, explaining the variability of clinical manifestations between mild and severe.
Subtle activism: Heterotopic principles for unsettling contemporary academia from within
Authors: Kjærgaard Annemette , Bergmann Rasmus , Blasco Maribel , Padan Tali , Elliott Carole , Callahan Jamie , Robinson Sarah , Wall Tony
Published: April 2023

Research on academic activism tends to foreground vociferous and explicit forms of activism that pursue predefined political agendas. Against this backdrop, this article proposes that academic activism can take more subtle forms. Writing as an academic activist collective, we unpack what subtle activism might look like within the context of contemporary academia. We use Foucault’s concept of heterotopia to argue that subtle activism can expand the space of what is possible in academia today by experimenting with quietly unsettling norms rather than overtly opposing or rejecting them. We offer a set of principles that might underpin a subtle activist agenda, extrapolated from practices from colleagues and from own activist collective. We hope that these principles may serve to inspire other academics wishing to engage in subtle activism by unsettling everyday practices that discreetly challenge the status quo, thereby contributing to gently shifting the agenda for how it is possible to conduct intellectual work in the contemporary neoliberal university context.
What behavioral beliefs could robot-served hotels focus on to attract potential consumers?
Authors: Zubizarreta-Barrenetxea Leire , Barrutia Jose M. , Marcos Aitor
Published: April 2023

Service robots could provide benefits for hotels in terms of productivity and even service quality. However, hotel managers in Spain (and Europe) have not implemented them as yet or are doing so only tentatively. This could be due to the fact that current literature is fragmented (i.e., dominated by hybrid models) and inconclusive and does not provide consistent guidelines for practitioners. This research narrows this gap by showing that a parsimonious application of the Theory of Planned Behavior is useful to predict attitude and buying intention toward robot-served hotels. Through an empirical analysis of 600 consumers in Spain, our findings indicate that hotel managers could focus on intrinsic motivations (enjoyment and challenge). They should also communicate the advantages of hybrid human–robot teams, in which the robots supplement humans instead of substituting them. The anthropomorphism of robots should not be emphasized as it seems to be perceived as a threat. Although utilitarian benefits matter, they seem to have a subordinate salience.
Socioeconomic, medical and demographic characteristics of early adopters of digital primary care
Authors: Dahlstrand Amanda , Farrokhnia Nasim
Published: April 2023

Aims:

In this paper, we investigated which socioeconomic and demographic groups first adopted digital primary care video consultations when they became accessible to the entire population in Sweden.

Methods:

We analysed data on all patients (378,000) who had a consultation with the largest provider of digital healthcare in Sweden – Kry – in the first years of national availability of the service, 2016–2018. We studied their income, education, demographics, and diagnosis backgrounds using matched registry data. Moreover, to compare users and non-users of digital primary care, we used data on all physical primary care users in one Swedish region: Skåne.

Results:

We found that this digital primary care was first used by young and higher-income adults, but not far from half of adult users had incomes below the national median. Digital care patients were more educated than the general population, reflecting that urban inhabitants were more likely than rural inhabitants to be users. First-generation immigrants were less represented among digital care users than in the population. However, second-generation immigrants with two foreign parents were slightly over-represented. The prevalence of some chronic diseases in pre-digital secondary (specialist and hospital) healthcare data among digital care users was similar to the population adjusted for age. Studying all physical primary care users in Skåne region, young digital care users had more primary care diagnoses and previous in-person primary care appointments than non-users, while the pattern was reversed for older users.

Conclusions:

When digital primary care became nationally available, younger, urban and more educated patients were the first to adopt the new technology. Regarding medical history, young users of digital care had a higher previous disease burden than young non-users, suggesting that these digital services were first adopted by young people with high primary care needs.
Performance assessment of steel cantilever beams based on connection behaviour using DIC technique and improved hybrid PSO algorithm
Authors: Khaloo Alireza , Amirahmadi Amirhossein
Published: April 2023

Cantilever beams can have various behaviour depending on the details of the connection. Partially-fixed connections have a different performance from conventionally-fixed connections, in which the exact information is not available. In this paper, using the finite element model updating (FEMU) of a steel cantilever beam, the support conditions of a partially-fixed connection and the behaviour of the beam are investigated. The FEMU is utilized as an appropriate technique for structural health monitoring, which requires the use of data acquisition methods from the structure. In this research, instead of using discrete sensors, displacement and strain information are continuously measured from the beam surface using the digital image correlation (DIC) method. The difference between the initial model and the data extracted from the DIC is determined by a cost function. A hybrid method called Powell particle swarm optimization is used to minimize the cost function. This method includes particle swarm optimization (PSO) as a global search technique and Powell optimization as a local search technique; the hybrid method achieves better performance by combining the two methods. A dynamic inertia weight is presented to improve the performance of the PSO algorithm. Abaqus software and Python programming have been used to carry out the FEMU process. Finally, the amount of rotation and displacement of support are calculated, and the dependency of beam behaviour on each of the variables is investigated. This method yields acceptable convergence of the results and can be extended to study other structural components.

Published: April 2023

To accurately diagnose the quayside container crane (QCC) gearbox faults, this article proposes a method that combines the frequency-domain Markov transformation field (FDMTF) and multi-branch residual convolutional neural network (MBRCNN). Firstly, the gearbox vibration signal is converted into the frequency domain to reveal the components and amplitude of signals stably and concisely. Then, the one-dimensional frequency signal is encoded into the two-dimensional image by the Markov transformation field to capture the dynamic characteristics of signals. Thirdly, the MBRCNN network is constructed, which can extract multi-scale features and alleviate the problems caused by the deep network structure. Finally, the FDMTF image is fed into the constructed MBRCNN model for pattern recognition. The effectiveness of the proposed FDMTF–MBRCNN method is verified by two case studies. In Case 1, the diagnosis results of a benchmark dataset achieve 100% accuracy, better than seven state-of-the-art methods published in recent 3 years. In Case 2, the diagnosis results of the dataset collected from a 1:4 scaled test rig achieve 98.85% accuracy, better than eleven encoding methods and four convolutional neural network methods. It also can obtain a recognition accuracy of more than 94% under the conditions of small sample, different network hyper-parameters, or variable loads, which verifies its robustness. These case studies show that the FDMTF–MBRCNN method is expected to be applied to the actual fault diagnosis of QCC gearboxes.

Reliable dynamic model of gear system with pitting can be utilized to investigate the effects of surface pitting on vibration response and to identify its severity. In this study, a dynamic model with pitting based on image processing is proposed, and pitting is simulated through the discrete tooth surface. The contact points are modeled by a network of linear springs with different stiffness in parallel. The revised mesh stiffness is calculated and a new mesh stiffness calculation method with surface pitting is proposed, which combines pixel matrix with mesh stiffness to improve the accuracy and efficiency of calculation. The dynamic model is validated by comparison with experimental test signals under different rotations and pitting states. As the Hilbert–Huang transform energy spectrum method has been applied for the detection of the vibration signals with small pitting areas, the signal characteristics caused by pitting can be well represented based on the statistical indicators and energy spectrum.

First year nursing students at a small public university participated in a longitudinal study following a bridge course to prepare them for the transition to college and rigorous nursing curriculum. The bridge course included activities to identify challenges and strategies for success, develop belonging with peers and faculty, and explore students’ capacity for resilience. Employing a mixed-methods approach, the four-year study tracked admission metrics and academic progression and gathered qualitative data through interviews and a focus group. Descriptive statistics examined the impact of success indicators at time of admission to the program, and qualitative responses explored ways the bridge program and subsequent supports may have influenced persistence. No single student attribute predicted success, and multiple supportive factors enabled on-time graduation. This study may offer valuable insights into effective strategies for retaining nursing students, enabling them to graduate in four years and become licensed to join the nursing workforce.

Mechanical ventilation (MV) is a lifesaving therapy for patients with acute or chronic respiratory failure. Despite, it can also cause lung injury by inducing or worsening inflammatory responses and oxidative stress. Several clinical approaches have protective effects on the lungs, including the prone position and exogenous surfactant; however, few studies have evaluated the association between the two strategies, especially in individuals without previous lung injury. We tested the hypothesis that the effects of the homogenization in lung aeration caused by the prone position in association with the anti-inflammatory properties of exogenous surfactant pre-treatment could have a cumulative protective effect against ventilator-induced lung injury. Therefore, Wistar rats were divided into four experimental groups: Mechanical Ventilation in Supine Position (MVSP), Mechanical Ventilation in Prone position (MVPP), Mechanical Ventilation in Supine Position + surfactant (MVSPS), and Mechanical Ventilation in Prone Position + Surfactant (MVPPS). The intranasal instillation of a porcine surfactant (Curosurf®) was performed in the animals of MVSPS and MVPPS 1 h before the MV, all the rats were subjected to MV for 1 h. The prone position in association with surfactant decreased mRNA expression levels of pro-inflammatory cytokines in ventilated animals compared to the supine position; in addition, the NfκB was lower in MVPP, MVSPS and MVPPS when compared to MVSP. However, it had no effects on oxidative stress caused by MV. Pre-treatment with exogenous surfactant was more efficient in promoting lung protection than the prone position, as it also reduced oxidative damage in the lung parenchyma. Nevertheless, the surfactant did not cause additional improvements in most parameters that were also improved by the prone position. Our results indicate that the pre-treatment with exogenous surfactant, regardless of the position adopted in mechanical ventilation, preserves the original lung histoarchitecture, reduces redox imbalance, and reduces acute inflammatory responses caused by mechanical ventilation in healthy adult Wistar rats.

With the rapid development of unmanned ground vehicle industry, how to achieve continuous, reliable, and high-accuracy navigation becomes very important. At present, the integrated navigation with global navigation satellite system and strapdown inertial navigation system is the most mature and effective navigation technology for unmanned ground vehicle. However, this technique depends on the signal accuracy of global navigation satellite system. When the receiver cannot capture four or more satellite signals for a long time or the satellite completely invalid, it cannot provide accurate navigation and positioning information for the unmanned ground vehicle. Therefore, this article combine the observation information of strapdown inertial navigation system, global navigation satellite system, and laser Doppler velocimeter to propose a high-precision seamless navigation technique of unmanned ground vehicle based on state transformation extended Kalman filter. Under different land vehicle driving environments and global navigation satellite system signal quality conditions, the seamless navigation technique is evaluated through global navigation satellite system interruption simulation and land vehicle experiments. The experimental results show that the strapdown inertial navigation system/global navigation satellite system/laser Doppler velocimeter tightly coupled integration seamless navigation has good environmental adaptability and reliability and can maintain high navigation accuracy under high frequency global navigation satellite system–signal blockage conditions in urban areas.
