Investigating the factors affecting educators’ adoption of learning analytics using the UTAUT model
Authors: El Alfy Shahira , Kehal Mounir 
Published: June 2024

PurposeThe research aims at examining educators’ perceptions, attitudes and behavioral intentions toward learning analytics (LA) and the role of self-instruction within the proposed model for LA adoption.Design/methodology/approachA quantitative approach is utilized in which a questionnaire is designed as a tool for data collection and partial least squares structural equation modeling (PLS-SEM) is used for data analysis and model testing.FindingsResults show that performance expectancy and effort expectancy have a significant effect on educators’ attitudes, which in turn significantly affect educators’ behavioral intentions. Self-instruction mediates the relationship between educators’ attitudes and behavioral intentions. The attitude towards LA mediates the relationship between LA performance expectancy and educators’ self-instruction. The research model explains 54% of the variance in learning analysis adoption.Originality/valueFindings open a path for research on pedagogical factors affecting LA adoption and guide education managers toward facilitating LA adoption. The tested model contributes to LA and teaching and learning literature by highlighting the role of educators’ self-instruction in LA adoption.

Published: June 2024

PurposeA risk-based method is proposed to identify the dominant influencing factors of secondary lining cracking in an operating mountain tunnel with weak surrounding rock.Design/methodology/approachBased on the inspection data from a mountain tunnel in Southwest China, a lognormal proportional hazard model is established to describe the statistical distribution of secondary lining cracks. Then, the model parameters are obtained by using the Bayesian regression method, and the importance of influencing factors can be sorted based on the absolute values of the parameters.FindingsThe results show that the order of importance of the influencing factors of secondary lining cracks is as follows: location of the crack on the tunnel profile, rock mass grade of the surrounding rock, time to completion of the secondary lining, and void behind the secondary lining. Accordingly, the location of the crack on the tunnel profile and rock mass grade of the surrounding rock are the two most important influencing factors of secondary lining cracks in the investigated mountain tunnel, and appropriate maintenance measures should be focused on these two aspects.Originality/valueThis study provides a general and effective reference for identifying the dominant influencing factors of secondary lining cracks to guide the targeted maintenance in mountain tunnels.
Crowdsourcing-based social linkage and organizational innovation competence: knowledge transfer effectiveness and absorptive capacity as serial mediators
Authors: Mishra Divya , Maheshwari Nidhi 
Published: June 2024

Purpose
The purpose of this research is to examine the impact of crowdsourcing-based social connections on the development of innovation competence (IC). The conflicting results in existing studies regarding the influence of crowdsourcing-based social linkage on IC necessitate a thorough investigation into this relationship.

Design/methodology/approach
The research uses a sample of 300 senior managers from various industries in India. The data is analyzed using partial least squares (PLS), a component-based approach to structural equation modeling.

Findings
The results of the analysis indicate that knowledge transfer effectiveness and absorptive capacity (ABC) play a significant role as mediators in the relationship between social linkages based on crowdsourcing and IC. This suggests that the effectiveness of knowledge transfer and the organization’s ability to absorb and apply new knowledge are crucial factors in leveraging crowdsourcing-based social connections for enhanced innovation capabilities.

Practical implications
The findings of this study hold crucial implications for managerial practices. The research highlights that successful crowdsourcing outcomes necessitate more than mere establishment of external social linkages. Managers must recognize that internal organizational readiness plays an equally critical role. This study offers two key managerial insights: first, exclusive focus on external linkages is inadequate; internal capabilities such as ABC and optimized knowledge transfer processes must be actively nurtured. Second, the concept of “crowdsourcing maturity” is introduced, emphasizing the evolving dynamic capabilities over time. Managers are urged to adopt a balanced approach, aligning external partnerships with internal adaptability, to fully optimize IC.

Originality/value
This research contributes to the existing body of knowledge by shedding light on the mediating variables that influence the conversion of crowdsourcing-based social linkage into improved IC. By considering the role of knowledge transfer effectiveness and ABC, the study provides insights into the mechanisms through which social linkages based on crowdsourcing can impact innovation capabilities. These findings offer valuable implications for organizations seeking to leverage crowdsourcing for innovation purposes and enhance their overall IC.

AbstractBackgroundPlatelet transfusions are frequently used in the intensive care unit (ICU), but current practices including used product types, volumes, doses and effects are unknown.Study design and methodsSub‐study of the inception cohort study ‘Thrombocytopenia and Platelet Transfusions in the ICU (PLOT‐ICU)’, including acutely admitted, adult ICU patients with thrombocytopenia (platelet count <150 × 109/L). The primary outcome was the number of patients receiving platelet transfusion in ICU by product type. Secondary outcomes included platelet transfusion details, platelet increments, bleeding, other transfusions and mortality.ResultsAmongst 504 patients with thrombocytopenia from 43 hospitals in 10 countries in Europe and the United States, 20.8% received 565 platelet transfusions; 61.0% received pooled products, 21.9% received apheresis products and 17.1% received both with a median of 2 (interquartile range 1–4) days from admission to first transfusion. The median volume per transfusion was 253 mL (180–308 mL) and pooled products accounted for 59.1% of transfusions, however, this varied across countries. Most centres (73.8%) used fixed dosing (medians ranging from 2.0 to 3.5 × 1011 platelets/transfusion) whilst some (mainly in France) used weight‐based dosing (ranging from 0.5 to 0.7 × 1011 platelets per 10 kg body weight). The median platelet count increment for a single prophylactic platelet transfusion was 2 (−1 to 8) × 109/L. Outcomes of patients with thrombocytopenia who did and did not receive platelet transfusions varied.ConclusionsAmong acutely admitted, adult ICU patients with thrombocytopenia, 20.8% received platelet transfusions in ICU of whom most received pooled products, but considerable variation was observed in product type, volumes and doses across countries. Prophylactic platelet transfusions were associated with limited increases in platelet counts.
Laparoscopic herniorrhaphy for inguinal hernia with thanatophoric dysplasia: A case report
Authors: Tanaka Keiichiro , Abe Kumpei , Koizumi Masato , Takahashi Toshiaki , Sugiura Hiroshi 
Published: June 2024

AbstractThanatophoric dysplasia (TD) is a rare and severe type of skeletal dysplasia. Typical clinical findings include macrocephaly, shortening of the four limbs, underdeveloped lungs, and thoracic hypoplasia. Neonates with TD develop severe respiratory problems due to thoracic hypoplasia and require respiratory management for survival. Despite the resolution of respiratory problems, long‐term survival cases are rare. Previous studies have reported that surgical procedures in patients with TD are limited to those necessary for survival, including tracheostomy, laminectomy, and ventricular shunt. A 1‐year‐old boy with TD was treated with laparoscopic herniorrhaphy. To the best of our knowledge, this is the first report of TD treated with laparoscopic procedure.
Giant symptomatic splenic cyst treated with laparoscopic fenestration using single‐incision plus one‐port laparoscopic surgery: A case report

Published: June 2024

AbstractLaparoscopic fenestration is the preferred treatment for symptomatic splenic cysts because it is curative and spleen‐sparing. We report a case of a 25‐year‐old female who underwent laparoscopic fenestration for a giant splenic cyst using a single‐incision plus one‐port approach. She presented to our hospital with repeated vomiting. Imaging showed a 23 × 18 cm splenic cyst with no solid components, strongly compressing the stomach to the right side. Laparoscopic fenestration was initiated through a 2.5‐cm umbilical incision, and a 5‐mm port was added in the left abdomen intraoperatively. The drain placement was deemed necessary to prevent abscess formation and post‐operative bleeding because of a thick cyst component and unexpectedly thick wall. Splenic cysts are typically benign and commonly develop in young people, hence, organ preservation and cosmetic results are crucial. Laparoscopic fenestration using single‐incision plus one‐port is considered to be an appropriate procedure for giant splenic cysts with non‐serous contents.
Integrating science‐based and local ecological knowledge: a case study of mangrove restoration and rehabilitation projects in the Philippines
Authors: Marquez Gian Powell B. , Olavides Ronald Dionnie 
Published: June 2024

AbstractMangrove forest is an ecosystem‐based solution for disaster risk reduction in the Philippines, but its historical deforestation has hampered its capacity to protect coastal communities. With the increasing occurrence of storm surge in the Philippines, mangrove reforestation projects have received renewed attention, but many have failed. Community participation was deemed to be essential in those projects that did well. Hence, this paper examines successful mangrove restoration and rehabilitation projects in the Philippines to find out how community participation contributed to the accomplishments. The study found that while the transfer of science‐based ecological knowledge from project managers to the community is an important factor in ensuring successful initial planning and implementation, its integration into existing local ecological knowledge—‘localisation’ of science‐based ecological knowledge or hybrid ecological knowledge formation—helped to facilitate long‐term community‐based mangrove management beyond project duration by empowering community members and enabling project acceptance and ownership. Still, continuous local institutional support is a necessary anchor for community resilience.
Human perception of flicker‐fused letters that are luminance balanced
Authors: Greene Ernest , Morrison Jack 
Published: June 2024

AbstractThe Talbot–Plateau law specifies what combinations of flash frequency, duration, and intensity will yield a flicker‐fused stimulus that matches the brightness of a steady stimulus. It has proven to be remarkably robust in its predictions, and here we provide additional support though the use of a contrast discrimination task. However, we also find that the visual system can register flicker‐fused letters when the combination of frequency and duration is relatively low. The letters are recognized even though they have the same physical luminance as background. We hypothesize that the letters elicit synchronous oscillations that encode for stimulus attributes, which prevents the letter from blending into the background.

AbstractLung adenocarcinoma (LUAD) is the most prevalent subtype of lung cancer, and the early detection and diagnosis of this disease are crucial in reducing mortality rates. The timely diagnosis of LUAD is essential for controlling tumour development and enabling early surgical treatment. GPR56 is a vital G protein‐coupled receptor and its role in T lymphocytes has received considerable attention. However, its function in B cells remains unclear. This study aimed to investigate the significance of GPR56 in LUAD. We found that GPR56 exhibited a significant increase in circulating plasmablasts and a decrease in new memory B cells. GPR56 expression in B cells was significantly reduced after LPS stimulation and the proportion of HLA‐DR+ and CD40+ proportions were also decreased in GPR56+ B cells after stimulation. Additionally, GPR56 exhibited significant down‐regulation in circulating B cell subsets of early‐stage LUAD patients, and there were significant correlations between GPR56+ B cell subsets and tumour markers. In conclusion, GPR56 could reflect the hypoactivation state of B cells and the decreased proportion of GPR56+ B cell subset in LUAD patients can signify the active humoral immunity in vivo. The expression of GPR56 in B cells could potentially hold value in the early diagnosis of LUAD.

Authors: Wu Chunyan , Yan Jiali , Wu Yun 
Published: June 2024

AbstractAimAngiogenesis inhibitor apatinib targets vascular endothelial growth factor receptors and improves the outcomes of patients with gynecologic malignancy. This study aimed to evaluate the efficacy and safety of angiogenesis inhibitor apatinib plus chemotherapy in recurrent platinum‐resistant ovarian cancer (RPR‐OC) patients.MethodsThis study retrieved 67 RPR‐OC patients who received apatinib plus chemotherapy or chemotherapy alone and divided them into apatinib + chemo (N = 30) and chemo alone (N = 37) groups according to the actual medication.ResultsObjective response rate (36.7% vs. 16.2%, p = 0.056) and disease control rate (80.0% vs. 59.5%, p = 0.072) showed an increased trend in apatinib + chemo group versus chemo alone group. The progression‐free survival (PFS) (p = 0.010) and overall survival (OS) (p = 0.042) were prolonged in apatinib + chemo group versus chemo alone group. The median (95%confidence interval [CI]) PFS was 5.9 (5.5–6.3) months in apatinib + chemo group and 3.8 (2.0–5.6) months in chemo alone group. The median (95%CI) OS was 20.5 (16.5–24.5) months in apatinib + chemo group and 13.6 (8.6–18.6) months in chemo alone group. Apatinib plus chemotherapy was independently related with better PFS (hazard ratio [HR]: 0.354, p < 0.001) and OS (HR: 0.116, p < 0.001). Subgroup analyses indicated that patients with a more serious disease condition might benefit more from apatinib plus chemotherapy. No difference was found in adverse events of all grade or grade ≥3 between the two groups (all p > 0.05).ConclusionAngiogenesis inhibitor apatinib plus chemotherapy shows better treatment efficacy than chemotherapy alone with controllable safety profile in RPR‐OC patients.

Published: June 2024

AimThe current study aims to investigate the association of serum brain‐derived neurotrophic factor (BDNF) levels with symptoms of depression in adults with and without prevalent cardiovascular disease (CVD), an often burdensome comorbidity.MethodsThis cross‐sectional study included participants from FHS (Framingham Heart Study) who had available serum BDNF levels. Depressive symptoms were assessed using the Center for Epidemiological Studies–Depression Scale (CES‐D) with a score ≥16 indicating mild to moderate and ≥21 severe depression. Participants taking antidepressant medications were excluded from the study.ResultsAltogether 3716 FHS participants were included in the final analysis (mean age, 64.3 ± 11.5 years; 55% women). After adjusting for potential confounders, greater BDNF levels were associated with reduced severe depression risk (odds ratio [OR], 0.78 [95% CI, 0.64–0.96]; P = 0.016). Among participants with CVD, greater BDNF levels were related to lower risk of depressive symptoms (CES‐D ≥ 16 OR, 0.63 [95% CI, 0.45–0.89], P = 0.008; CES‐D ≥ 21 OR, 0.49 [95% CI, 0.31–0.76], P = 0.002). The inverse relationship between BDNF and depressive symptom risk was present in women with CVD (CES‐D ≥ 16 OR, 0.63 [95% CI, 0.40–0.99], P = 0.047; CES‐D ≥ 21 OR, 0.38 [95% CI, 0.21–0.70], P = 0.002) but not in men.ConclusionLower serum BDNF levels are associated with a higher risk of depressive symptoms in CVD, particularly among women. These findings implicate BDNF in the complex biological mechanisms that underlie prior associations observed between CVD and depression. To reduce the burden of depression in the large proportion of midlife and older adults with CVD, a better understanding of how BDNF may modify these pathways is merited.
Latine children's attributions of cultural and structural discrimination and the role of neighborhood context

Published: June 2024

AbstractWe investigated first‐and second‐generation Latine immigrant children's attributions for cultural and structural discrimination, and how this differed based on their own neighborhood composition. Participants were recruited from 19 elementary schools (N = 101 girls, 101 boys), and ranged in age from 8 to 12 years old (M = 9.22; SD = 11.98 months). All children were either first‐generation (40%) or second‐generation (60%) immigrants from Mexico, South America, and Central America. Mixed ANCOVAs analyzed how attributions of structural and cultural discrimination differed based on children's perceptions of ethnic residential composition. The findings indicated that elementary school‐aged Latine children, regardless of neighborhood composition, were aware of the biased cultural narrative that Latine immigrants are “criminals.” This seems to be the most salient form of cultural discrimination for children in middle childhood and echoes much of the political rhetoric around immigration reform. Children's own neighborhood composition predicted their understanding of residential segregation. Children who lived in predominantly White neighborhoods perceived segregation to be due to White people's biases, whereas children who lived in predominantly Latine neighborhoods perceived segregation to be due to Latine families’ economic disadvantage or both groups’ mutual preferences. These findings suggest that Latine children, by middle childhood, are aware of biased cultural narratives in the U.S., and their understanding of structural inequalities are related to the neighborhood context in which they live.
The geography of Hispanic political behavior in Texas, 2012–2022
Authors: Hood M. V. , McKee Seth C. 
Published: June 2024

AbstractObjectiveWe make use of multiple data sources to examine whether there has been geographical polarization in the political behavior of Texas Hispanics from 2012 to 2022. It is widely known that partisan divisions in the American electorate continue to cleave along geographic lines. However, much of this literature on the urban–rural divide does not focus on a specific racial group, and if it does, then it typically highlights differences among non‐Hispanic white voters (Anglos).MethodsMaking use of aggregate‐ and individual‐level data, we assess Texas Hispanics’ party affiliation, participation, and vote choice according to geographic location.ResultsWe find notable evidence of geographic‐based partisan polarization among Texas’ burgeoning Hispanic population.ConclusionsAlthough the movement of rural/small town Texas Hispanics toward the Republican Party from 2012 to 2022 pales in comparison to this shift among Texas Anglos, a similar partisan dynamic manifests among the former group. We abstain from using the word realignment to characterize these changes in Texas Hispanics’ political behavior according to geographic location, but, nevertheless, it is clear that the Democratic Party's hold on this potentially pivotal group in the Lone Star State's electorate has loosened, and especially among rural/small town Latinos since the rise of Donald Trump.
Ethnical incomes’ gap in Spain. The case of Roma
Authors: Pinto Fernando , Malo Miguel Ángel , Martínez Rosa 
Published: June 2024

AbstractBackgroundDiscrimination against Roma individuals is a prevalent issue across Europe, presenting significant socio‐economic challenges. Spain, holding the highest concentration of Roma in Western Europe, serves as a focal point for investigating such disparities.ObjectivesThis study aims to explore the wage gap between the Roma and non‐Roma populations in Spain, assessing the extent to which this disparity may be attributed to potential discriminatory practices. The objective is to provide a detailed analysis of wage inequalities to inform more effective anti‐discrimination policies.MethodsThe analysis utilizes data from the 2018 Survey on Social Integration and Social Needs, employing statistical and econometric techniques. This approach helps in quantifying the wage gap and in examining the factors contributing to the observed disparities between the two groups.ResultsThe findings indicate a substantial wage gap between the Roma and non‐Roma populations. Approximately 43.5 percent of the wage difference remains unexplained by the standard variables included in the econometric model, suggesting that factors beyond educational and professional qualifications might contribute to these inequalities.ConclusionThe significant unexplained portion of the wage gap likely points to the existence of ethnic discrimination by employers. This study underscores the urgent need for nuanced, targeted anti‐discrimination interventions specifically designed for the Roma community in Spain. The results advocate for policy adjustments that address these disparities at their core, ensuring equity and social integration.
