Human Interest: Usury from Luther to Bentham
Authors: Bradley Arthur
Published: November 2023

This article revisits a set of classic political, theological and economic scenes in the (early) modern debate on usury from Luther to Bentham. To summarize, I argue that this theory of usury – which polemically mobilizes counter-Aristotelian tropes of the breeding, reproduction and husbandry of money – might also be read as a theory of what Foucault famously calls pastoral power. If this debate nominally concerns the ‘repeal’ of the ancient prohibition against money-lending at interest, I argue that what is really at stake here is the pastoral production of a new theory of the subject as ‘human interest’: a self whose allegedly intrinsic self-interest expresses itself paradigmatically through financial interest. In conclusion, I situate this genealogy of human interest within the larger history of the self-interested, capitalist and indebted subject from Hirschman, through Foucault, to Lazzarato.
Repairability as a Condition of the World: Ernesto Oroza’s Archive of Dis/repair
Authors: Benjamin Lucy
Published: November 2023

In an age of apparent disrepair as the climate crisis takes hold and neoliberalism fails to liberate, as the cost of living rises and rights are retracted, the need for a reparative turn is overdue. But what is repair? If repair is contained in moments of total breakdown, then the reparative acts of care that sustain the world are denied. Countering these forces and the urgency prescribed by the crisis of disrepair and in what too often appears as the proprietary epistemology of repair, in this paper I offer an account of ‘repairability’. Structured in relation to the reparative gaze of feminist theory and poetic thinking, repairability assumes a material trace, I contend, through the vernacular archive of Cuban artist-ethnographer Ernesto Oroza. Oroza’s work offers a compelling case study through which to think the possibility of repair as an act of worldly becoming.

Published: November 2023

Introduction

Thrombotic and haemorrhagic complications have been reported following transcatheter aortic valve implantation (TAVI). However, few reports have studied perioperative changes in coagulation and platelet function after TAVI. Furthermore, there are no clear guidelines for antithrombotic therapy. This study aimed to examine the perioperative changes in coagulation and platelet contribution to clot strength after TAVI using thromboelastography (TEG 6s; Hemonetics).

Methods

This prospective observational study included 15 patients scheduled to undergo TAVI for severe aortic stenosis. TEG 6s global haemostasis was used to record three measurements: on the day of surgery (immediately before the operation) and postoperative days 1 and 3. The reaction time R to thrombosis; K and α, which represent the rate of thrombosis; and the maximum amplitude (MA) were measured from the kaolin thromboelastography (TEG) curves. The coagulation index (CI) was calculated from the measurement results to assess thrombotic tendency. In addition, MA was converted to elastic clot strength, and platelet function was assessed by the difference, Gp, in elastic strength depending on platelet activation.

Results

R and K decreased, and α tended to increase in kaolin TEG on days 1 and 3 after TAVI, indicating elevated coagulation function compared with the preoperative period, but MA and CI did not show significant changes. Gp decreased significantly on days 1 and 3, suggesting a decrease in the platelet contribution to clot strength.

Conclusions

Compared with the preoperative period, coagulation tended to increase, and platelet contribution to clot strength decreased from days 1 to 3 after TAVI.
Forced convective heat transfer in vegetation by measuring liquid water evaporation
Authors: Sung Kunhyuk , Mueller Eric , Hamins Anthony
Published: November 2023

A series of experiments was conducted to develop a method to estimate the convective heat transfer in vegetative fuels with a complex geometry through the measurement of liquid water evaporation. A water mist was sprayed onto vegetative test specimens, coating their entire surface with a thin water layer. The water evaporation rate was measured using a load cell in a wind tunnel under controlled conditions while an infrared camera tracked the surface temperatures. Convective heat transfer was calculated by the difference between the free stream and surface temperatures and the measured evaporation rate, considering the energy balance of the water layer at steady state. The method was verified through evaporation tests using a wood cylinder array. Experiments were conducted using nominally 30 cm branches of a typical conifer, Norway Spruce ( Picea abies), yielding the conventional form of the Nusselt number–Reynolds number power–law relationship: Nu=C Ren Pr1/3 with coefficients C = 0.69 ± 0.25 and n = 0.34 ± 0.06.

Published: November 2023

This study examined how well people can recognize and relate to animated pedagogical agents of varying ethnicities/races and genders. For both Study 1 (realistic-style agents) and Study 2 (cartoon-style agents), participants viewed brief video clips of virtual agents of varying racial/ethnic categories and gender types and then identified their race/ethnicity and gender and rated how human-like and likable the agent appeared. Participants were highly accurate in identifying Black and White agents but were less accurate for Asian, Indian, and Hispanic agents. Participants were accurate in recognizing gender differences. Participants rated all types of agents as moderately human-like, except for White agents. Likability ratings were lowest for White and male agents. The same pattern of results was obtained across two independent studies with different participants and different onscreen agents, which indicates that the results are not solely due to one specific set of agents. Consistent with the Media Equation Hypothesis and the Alliance Hypothesis, this work shows that people are sensitive to the race/ethnicity and gender of onscreen agents and relate to them differently. These findings have implications for how to design animated pedagogical agents for improved multimedia learning environments in the future and serve as a crucial first step in highlighting the possibility and feasibility of incorporating diverse onscreen virtual agents into educational computer software.

Published: November 2023

The biosafety and degradability of nanocarriers have always been an important factor restricting their entry into the clinic. In this work, a new nano-system was prepared by coating the photothermal effect of dopamine-doped mesoporous silica nanoparticles with carboxymethyl chitin through electrostatic interaction, and is further anchored with folic acid on the surface for targeted delivery of anti-cancer the drug doxorubicin (DOX). The nano-system (DOX@PDA/MSN-CMCS-FA) is simply modified CMCS after being loaded with DOX and has good dispersibility, and the drug loading is 10.6%. In vitro release studies have shown that the release rate of PDA/MSN-CMCS-FA is 40% in pH 5.5. Effective degradation is debris in 14 d acidic environments. Due to the anti-infrared photothermal effects of PDA doping and DOX chemotherapy, the semi-lethal concentration (IC50) of nanoparticles (NPS) was 14.95 μg/mL, which can inhibit tumor cell growth by photochemical synergistic treatment, and have certain degradation performance.

Published: November 2023

Background and Purpose

Structuring scaffold with both osteogenic and angiogenesis capabilities is a challenge for bone tissue engineering. Powder structured Si-CaP materials have shown excellent osteogenic properties and induction of stem cell differentiation. Our research group have successful produced 3D printed Si-CaP scaffolds by DLP technology. This study aims to explore the angiogenic effects of SiO32- and Ca2+ released by 3D printed Si-CaP scaffold, and whether there is a synergistic effect between the two ions.

Methods

The 3D printed Si-CaP scaffolds were immersed in endothelial cell medium solution for 24 h. The Si, Ca ion released was detected by Inductively coupled plasma–optical emission spectrometry. We used detected data as a standard to prepare the simulated solution to investigate the effect of SiO32-, Ca2+ separately. Experiment was divided into control group, Si ion group, Ca ion group and Si + Ca ion group. We evaluated different ionic effect on HUVECs viability, proliferation, migration, gene expression, and tube formation on different groups.

Results

The concentration of SiO32- was detected as 15.71 ± 0.04 μg/mL, Ca2+ as 67.14 ± 0.95 μg/mL. Na2SiO3 and CaCl2 were used to prepare the simulated solution. There were no statistically difference between simulated solution from ion released by scaffold. Si + Ca group promoted the gene expression significantly compared with the control group, p < .01. Expression of vascular-associated protein in Si + Ca ion group was higher than that in Si ion group, Ca ion group and control group. Si + Ca ion group significantly enhanced endothelial cell on migration and tube formation assay.

Conclusion

The 3D printed Si-CaP scaffold can release effective physiological concentrations of Si, Ca ions. Si and Ca ions have a synergistic effect on promoting angiogenesis of HUVECs. 3D printed Si-CaP scaffold is promising in vascularized bone tissue engineering application.
A comparative study on the machinability of Mg-based composites: Cemented carbide and cubic boron nitride tools performance
Authors: Asgari Ali , Sedighi Mohammad , Delavar Hassan
Published: November 2023

Machining of metal matrix composites (MMC) is a challenging process as they are difficult to cut and cutting tools get worn out in a short time. In this paper, the performance of two industrial carbide grades and a cubic boron nitride (CBN) tool are assessed when machining of AZ91/SiC composites. Mg-based composites with different volume fractions and particle sizes are machined at various cutting conditions to evaluate the tools wear resistance and finished surface. The surface of the worn-out tools and machined samples are analyzed by scanning electron microscope (SEM), energy-dispersive X-ray spectroscopy (EDS), and roughness tester. Results revealed that the tool wear increased for composites reinforced by smaller particles regardless of the tool type. Additionally, tool grade TH1000 resulted in longer tool life when machining of Mg-based composites compared to the CP500 grade so that at a cutting speed of 70 m/min and feed rate of 0.1 mm/rev, tool life improved nearly 250%. CBN tools showed the best performance when machining of Mg-based composites as tools became worn out after 255 s which is considerable compared to carbide tools. Also, the finished surface caused by cemented carbide CP500 indicated the worst quality.
An experimental investigation into finite similitude for concrete structures

Published: November 2023

Currently, available conventional scaling methodologies are suffering from many deficiencies, which the most important ones can be listed as: (i) the inability to systematically capture the different material properties of full- and small-scale models, (ii) the inability to simultaneously fix two parameters having the same unit, and (iii) a limited number of independent degrees of freedom. To overcome these issues, a new theory called finite similitude has recently been developed. This paper aims to employ the recently introduced finite similitude theory for the scaled analysis of concrete structures. By conducting static three-point bending test on concrete beams at distinct scales, it is revealed that the response behavior of the prototype can be predicted to a good accuracy using small-scale trial models. Scaled-down models are designed based on the zeroth-order finite similitude theory and made from same and different granulations than the prototype. Also, the developed zeroth-order based scaling methodology enables us to experiment scaled-down plaster-rock structures rather than concrete structures. It is found that small-scale plaster-rock models, which can be prepared in much less time and at a lower cost, predict both local and global response behavior of the full-scale concrete structure with a high accuracy. Moreover, using the first-order finite similitude theory to take into account the elastic behavior and considering the scaled-down plaster-rock models as the second trial models, predictions of small-scale concrete models from the local response behavior of the full-scale model are significantly enhanced.

Published: November 2023

The Bolted joint loosening is challenging to describe with an accurate mathematical model. Therefore, a prediction model of bolted joint loosening was proposed based on a deep learning network. Firstly, the loosening experiments of the bolted joint were carried out with an orthogonal test. And the nonlinear and uncertain characteristics of bolted joint loosening process were further analyzed. Furthermore, a prediction model of bolted joint loosening based on a deep learning network was established. The proposed model was trained and verified using the experimental data. The results showed that compared with the traditional mathematical and regression models, the model could not only obtain the change of the mean value of preload but also describe the confidence interval of the change of preload in the sense of probability synchronously. The experiment data and prediction data are in good agreement, which can be used to validate the rationality of the model.

Published: November 2023

Manipulators applied to polishing can avoid the harm of dust and noise to workers’ health in manual polishing, and can significantly increase productivity. The degrees of freedom (DOF) of the existing end-effector for manipulator polishing is insufficient, and then it is difficult to adapt to complex surfaces. A passive compliant end-effector (PCEE) with 4-DOF employing pneumatic floating was designed to solve that problem in this article. According to the included angle between the floating spindle and the plunger, the supporting force functions of floating amount were constructed. Considering the characteristics of the supporting force and the operating modes comprehensively, an appropriate number of plungers was selected. Based on the equilibrium principle of spatial force system, a PCEE was designed by using the floating scheme at both ends, and then a physical model and a simplified model were provided. Eventually, the performances of 4-DOF PCEE are compared with those of the existing 2-DOF compliant end-effector (CEE). The results show that The PCEE can float with 4-DOF; when the number of plungers is 9, all performances meet the design requirements; the polishing force can adapt to the local bulges and overcome the error reflection; the 4-DOF PCEE can adaptively fit the surface to reduce its geometric error.

Published: November 2023

Butt joints made of 6061-T6 Al and AZ31B Mg dissimilar materials were fabricated using friction stir welding (FSW). Three welding techniques were used in the experimental process: method 1-Mg on the advancing side (AS), method 2-(Al on the AS), and method 3-(Mg was placed on the AS for the first welding experiment, and then the plate was rotated horizontally by 180° so that Al was placed on the AS for the second welding). Focus on the comparative analysis of the second welding and primary welding on the microstructure and mechanical properties of the joint. The results show that the joints with the secondary welding method have the characteristics of onion rings in the stirred zone (SZ), where there is a serious mixture of Al and Mg, and the degree of mechanical bonding is significantly increased. At the same time, the enhanced mechanical effect of secondary welding on the weld led to a change in the microhardness of the SZ. In the tensile tests, the strength of the secondary welded joint was increased to 120 MPa compared to the primary welded joint strength of 89 and 95 MPa due to the increase in the degree of mechanical bonding of the secondary welded joints and the increase in the level of mixing of plastic materials in the SZ. In addition, the type of fracture of the joint in all three welding methods is a brittle fracture.

Published: November 2023

Natural fiber based composites are gaining increased interest in industrial applications because of less weight, cheap and harmless. In this research work, natural composite was manufactured using Indian almond fiber by conventional hand layup process. The effect of fiber length (10, 20, and 30 mm) on the properties of composites was analyzed. Results showed that the composite made with 10 mm fiber length (C10) showed the utmost tensile strength (58 MPa). Further, the C10 composite was reinforced with Indian Jujube Fruit Seed (IJFS) particles and the effect of particles loading on composite’s behavior was examined. Results indicated that adding up IJFS particles assisted in progress of composite’s properties. Further, the C10/10 wt% IJFS composite showed the better mechanical properties (14% increase in tensile, 23% increase in flexural & impact strengths than C10 composite). Furthermore, the same composite showed least water absorption and bio-degradation characteristics. Hence, it is concluded from this research that the C10/10 wt% IJFS composite is best suited for structural applications as showed improved performance with low weight.

Authors: Asgari Ali , Sousanabadi Amin , Sedighi Mohammad
Published: November 2023

Metal matrix composites (MMC) introduced special features such as resistance to wear and high strength to weight ratio and these characteristics categorized them as difficult-to-cut materials in the field of machining. In the current paper, a novel study on the cutting fluid emulsion 5% role in the machinability of a magnesium-based metal matrix composite reinforced by silicon carbide (SiC) particles is presented. AZ91 magnesium alloy, with nominal composition Mg-9Al-1Zn, composites were made using stir casting method. Then, the composite samples were machined and the cutting parameters such as cutting speed, feed rate and side cutting edge angle were varied to assess their effects on the wear and surface roughness. To measure and analyze the wear, optical and scanning electron microscope (SEM) were used. Also, elemental analysis through energy-dispersive X-ray spectroscopy (EDS) was accomplished. Surface roughness of machined samples were measured by a profilometer and 3D surface topography. Results of SEM and EDS images indicated that SiC particles included in the composites act as grinders and remove the surface of tool even in a short time because of the severe abrasion. Additionally, surface of machined MMCs contains some defects such as cracks, broken SiC, and unwanted deformations. Using cutting fluid emulsion 5% enhanced the tool life as well as the surface quality remarkably for different cutting speeds, feed rates and cutting edge angles although finished surface of the samples were oxidized. Also, the cutting fluid considerably reduced the amount of adhered materials on the flank face.

Published: November 2023

The combustion of gasoline engines running on blends of compressed natural gas and hydrogen fuels was investigated using the quasi-dimensional and two-zone model. This model could investigate and predict the combustion characteristics, emissions, and performance parameters of petrol engines using MATLAB software. The impact of hydrogen inclusion to compressed natural gas on the cylinder temperature, pressure, cumulative work done, and heat transfer related to compressed natural gas was investigated. The engine’s thermal efficiency and output power were increased while specific fuel consumption was decreased when hydrogen was blended up to 20%. The highest decline in specific fuel consumption of 20% hydrogen was 25.1% for compressed natural gas. The torque values are 4.25, 4.34, 4.42, 4.51, and 4.60 N·m for compressed natural gas, hydrogen with compressed natural gas HCNG 5%, HCNG 10%, HCNG 15%, and HCNG 20%, respectively, at rated speed of 2500 r/min. The peak decreases in peak cylinder temperature and pressure for HCNG 20% compared to compressed natural gas are 5.9% and 5.2%, respectively. For HCNG 20%, the greatest cylinder pressure, temperature, and cumulative work done were 7.9 MPa, 2309.97 K, and 190.88 J, respectively. NO x emissions were increased for hydrogen-compressed natural gas blends but hydrocarbon emissions were decreased. In comparison to compressed natural gas, the highest hydrocarbon emission reduction is up to 2.64% for HCNG 20%. The model's validity was examined in comparison to the findings from the literature and the Diesel RK program. The results show that the MATLAB code is appropriate. Several alternative fuels can be used using this mathematical model.
Effect of tooltip profile and tilt angle on Al8090-TiH2/Al2O3 foam and its mechanical characterization
Authors: Mishra Smriti , Kumar Jatinder , Singh Hari
Published: November 2023

Metal foams are used for industrial purposes because of their lightweight structure, high specific modulus of elasticity, and excellent energy-absorbing capacity. Various techniques have been used for the development of metal foam. In the present study, Al8090 foam is fabricated by the uniform mixing of TiH2/Al2O3 particles with the help of the stirring action of the tool probe. The groove cutting method is used to prepare the Al metal matrix and friction stir processing is performed over the grooves for even dispersion of the blowing powder to produce the precursor of the localized aluminium (Al) foam. Special purpose inclined fixtures with different angles are fabricated to produce tilt on the three-axis vertical machining centre. Three different tip profiles, namely plane cylindrical, threaded cylindrical and square are selected for processing along with the fixture plate angle set at three levels of 1°, 1.5° and 2.5°. Tool rotational and traversing speed rate is kept constant and its influence has been assessed on the foam's porosity, hardness and compressive strength. Scanning electron microscopy and energy-dispersive X-ray spectroscopy tests have also been performed to analyse the foam's morphology and found that the square tip pin with 1.5° fixture plate angle has the best mechanical properties.
Influence of tool plunge depth and multiple passes on the microstructure, texture evolution and hardness of age-hardenable aluminium 7075 alloy
Authors: Girish G.
Published: November 2023

In this study, the surface properties of AA7075 were modified through the solid-state friction stir processing technique using a hexagonal-shaped H13 pin. Single pass friction stir processing was conducted at two different shoulder plunge depths at constant tool rotation and linear speeds with the resulting cross-sections being examined using optical macroscopy. Six friction stir processing passes were then carried out intermittently at optimal shoulder plunge depth and the corresponding microstructural evolution along the nugget was investigated using advanced microstructural characterization techniques such as electron backscatter diffraction and high-resolution transmission electron microscopy. Bulk texture examination was conducted using the neutron diffraction method, while hardness measurements were taken using Vicker's hardness testing machine. Single pass friction stir processing conducted at a shoulder plunge depth of 0.25 mm produced defect-free material consolidation with a refined grain structure along the nugget. Minimum grain size averaging 3.78 μm was observed at the top, while slightly increased grain sizes were noticed at the middle and bottom regions of the nugget. After 6 friction stir processing passes, grain size was reduced significantly averaging 1.84 μm at the top, while size at the pin-driven zone exhibited an increasing trend due to heat input and strain rate variations. Both, single-pass and 6 pass specimens exhibited a weaker texture along the nugget due to randomness in grain orientation and the effect of particle-stimulated nucleation mechanism. In the single-pass specimen, hardness decreased along the nugget, with a maximum of 85.2 HV at the top, while 6-pass specimen exhibited an improved hardness of 133.5 HV due to the strengthening caused by grain refinement, precipitates and dislocations.
Pyogenic spondylodiscitis in HIV-positive patients under antiretroviral therapy: A case series
Authors: Kitchen Maria , Gasslitter Irina , Gisinger Martin , Deeg Johannes , Rieger Armin , Sarcletti Mario
Published: November 2023

Background: The incidence of pyogenic spondylodiscitis has been increasing in countries of Europe and North America, probably due to an increasing number of persons with risk factors for this infection. It is unclear whether HIV infection in the era of antiretroviral therapy (ART) increases the risk for spondylodiscitis. Method: We present 7 cases of pyogenic spondylodiscitis of the cervical, thoracic, and lumbar spine in six individuals living with HIV under ART with suppressed viral load. Results: All patients presented with severe non-radicular pain and elevated inflammatory markers. Diagnosis was confirmed by magnetic resonance imaging (MRI) scan and isolation of the pathogen. Staphylococcus aureus was the causative pathogen in five patients. One patient suffered from an infection with Klebsiella pneumoniae followed by a mixed infection with Cutibacterium acnes and Bacillus circulans 18 months later. All patients needed surgical intervention, and the mean duration of antibiotic treatment was 17 weeks (range 12–26). Five patients recovered fully, including two persons who also suffered from endocarditis. One patient died from multi-organ failure. Conclusion: Spondylodiscitis may be seen more frequently in persons living with HIV as they grow older and suffer from comorbidities which put them at risk for this infection. HIV physicians should be aware of the infection and its risk factors.

Published: November 2023

This study aims to identify current offerings of research support services (RSS) by Pakistani university libraries to their research community at various phases of the research lifecycle. It also offers data on the future planning of libraries about RSS and compares the results with international studies to gauge the progress of Pakistani university libraries in this direction. This study used a quantitative design to collect data from 138 reference/head librarians of university libraries across four research lifecycle stages. The Cronbach alpha reliability of the questionnaire was 0.95, and the data were analyzed through Statistical Package for Social Sciences (SPSS). Frequency analysis and the Chi-square test were used to draw inferences. The results indicated that more than 50% of university libraries in Pakistan were providing most of the research support services associated with all stages of the research lifecycle. The majority of libraries offer traditional research support services as compared to advanced services which have been developed in recent times across the globe. The results of the study further indicated that private-sector university libraries were offering a higher level of research support services than public-sector university libraries. Furthermore, libraries associated with public sector universities showed more inclination toward offering these services as a part of their future planning. This study examined the current status of Pakistani university libraries’ research support services, grouped according to each stage of the research lifecycle. The study is an amalgamation of traditional and advanced research support services in order to give new dimensions to this area and the structured instrument designed for this study may be used by other researchers to conduct similar studies in their social setting. The findings will aid public sector university libraries in their efforts to provide their research communities with greater research support services. The results will be valuable to university and library administrators for strategic planning to meet the community’s need for research-based services.

Authors: Román-Calderón Juan Pablo , Franco-Ruiz Camilo , Robledo-Ardila Cristina
Published: November 2023

Despite their innovation practices, Latin American companies seem to show low levels of corporate entrepreneurship. More research on corporate practices directed at infusing an entrepreneurial climate in the region is needed. This study draws on a recent theory that brings together configuration theory with prior corporate entrepreneurship conceptualizations. With this study, the authors test whether innovation training programs increase the entrepreneurial climate of multinational corporations from Latin American emerging markets. The authors of this study collected data from a sample of 2,796 employees of a Colombian multinational, divided into two groups of trained and untrained staff. They hypothesise that the corporate entrepreneurship climate would be higher in the trained group. They specify and validate a series of multigroup structural equation models to test their hypothesis. The results of this study suggest that some dimensions of entrepreneurial climate are higher when companies implement innovation programs.

Published: November 2023

The case highlights the bankruptcy case of Kwality Limited, a significant Indian dairy company. Haldiram Snacks submitted a final bid of ₹1.45 billion to the Committee of Creditors for Kwality Limited, which is currently undergoing bankruptcy proceedings LiveMint (2019). This bid, a slight increase from their earlier rejected bid of ₹1.42 billion, has raised concerns due to its inadequate coverage of the company’s substantial outstanding debt of ₹19 billion Despite extensions, Haldiram Snacks remains the sole bidder, presenting a resolution plan under the Indian Insolvency and Bankruptcy Code (2016).

The bankruptcy process was initiated in 2018 by financial creditors KKR India Financial and Punjab National Bank. The bid’s insufficiency, covering less than 10% of the debt, prompts reflections on overlooked warning signs and preventive strategies for the future.

The larger context of the Indian dairy industry is provided, highlighting significant production and consumption figures, the growing organized dairy sector and the demand for value-added products. Kwality’s growth and expanding farmer network are briefly touched upon.

The case overviews Kwality Limited’s bankruptcy, Haldiram Snacks’ bid, the company’s history and performance, and the broader Indian dairy industry landscape. It underlines the bid’s shortfall in comparison to the outstanding debt and raises pertinent questions about the company’s downfall and preventive measures moving forward.
Welfare Benefits and Personal Connections in a Democracy: The Case of Muslims in West Bengal
Authors: Bose Saheli , Mukherjee Vivekananda
Published: November 2023

We study the association between social connections of Muslim households and their access to welfare benefits distributed by local governments in rural West Bengal. Using household data from selected villages in West Bengal, we find that Muslim households with higher outdegree centrality are associated with 2 percentage points probability of receiving a higher fraction of benefits from the local government than Hindu households with similar networks. This association is positive and significant for the benefits under housing and toilets. However, for the allocation of work under the Mahatma Gandhi National Rural Employment Guarantee Scheme, Hindu households with larger networks obtain more benefits. The results show that poorer Muslim households with a larger spread of network are associated with receiving more benefits.
Navigating Temporary Organizations: A Narrative Perspective
Authors: Rajan Jothsna , Jha Srivardhini K , Naik Gopal
Published: November 2023

Temporary organizations (TOs) can be viewed as a collection of narratives about the past and the future that can potentially shape organizational outcomes. An in-depth, longitudinal study of a time-bound inter-organizational project that served rural India's educational needs shows how multi-authored narratives and practices in temporary organizations influence each other. When the narratives are coherent with respect to the past and the future, the actors engage in mitigative practices, and the project develops. If the narratives diverge, the actors engage in self-serving practices hindering the project. The narrative view affords us a novel lens to understand the dynamics that shape practices and outcomes within temporary organizations. Our findings also have practical implications for TO management—understanding the plurality of narratives and emphasizing the importance of aligning them.

Published: November 2023

The purpose of this study was to describe experiences of pain among students at upper secondary schools (adolescents aged 16–19 years) in Sweden. Focus group (n = 9) interviews with 41 adolescents were conducted in southern Sweden in 2021. The interviews were analyzed by qualitative content analysis, which identified four categories encompassing the theme how pain expressed itself: (1) a warning bell—the body's way of saying that something is wrong; (2) school- and work-related pain; (3) interpersonal physical and emotional pain; and (4) heartache—a sign of humanity; and four categories describing the theme ways of dealing with pain: (1) turn your attention elsewhere; (2) “bite the bullet” and endure the pain; and (3) use painkillers or complementary treatments; and (4) ask for help from others. Findings are linked to the crucial role of school nurses in supporting students who experience pain.
Combination of Rivaroxaban and Amiodarone Increases Bleeding in Patients With Atrial Fibrillation
Authors: Wang Zi , Li Xiaoyu , Zou Ye , Li Xiaoye , Lv Qianzhou
Published: November 2023

Background:

Rivaroxaban and amiodarone are commonly used for treating patients with atrial fibrillation. Drug-drug interactions between rivaroxaban and amiodarone may increase exposure to rivaroxaban. However, the clinical relevance of this drug-drug interaction is still not clear.

Objective:

The aim was to investigate the risk of bleeding in patients receiving a combination of rivaroxaban and amiodarone.

Methods:

This was a prospective observational study in which we included atrial fibrillation patients treated with rivaroxaban. The patients were divided into the rivaroxaban group and the combination of rivaroxaban and amiodarone group (the combination group). Propensity score matching (PSM) and inverse probability of treatment weighting (IPTW) were performed to adjust between-group differences. The primary endpoint was defined as the time to the first occurrence of a composite of major, clinically relevant nonmajor, and minor bleeding.

Results:

In total, 481 atrial fibrillation patients were included in the analysis. After PSM, 154 patients in the rivaroxaban group were matched with 154 patients in the combination group. The bleeding events mainly consisted of clinically relevant nonmajor and minor bleeding. Only one patient experienced major bleeding. The primary outcome was recorded in 26.0% of patients in the combination group and 10.4% of patients in the rivaroxaban group (hazard ratio = 2.76, 95% CI = 1.55-4.93, P < 0.001). The bleeding risk was significantly higher in the combination group compared with that in the rivaroxaban group in the IPTW and stabilized IPTW analyses (hazard ratio = 2.17, 95% CI = 1.32-3.56, P = 0.002).

Conclusion and Relevance:

The combination of rivaroxaban and amiodarone increased the risk of bleeding in patients with atrial fibrillation, especially clinically relevant nonmajor and minor bleeding. Physicians prescribing rivaroxaban and amiodarone together should be concerned about an increase in the risk of nonmajor bleeding.
Does Emotion-Related Impulsivity Relate to Specific ADHD Symptom Dimensions, and Do the Effects Generalize Across Comorbid Internalizing and Externalizing Syndromes?

Published: November 2023

Background:

Recent work highlights the role of emotion dysregulation in the pathology of Attention-Deficit/Hyperactivity Disorder (ADHD). As such, emotion-related impulsivity (ERI), the trait-like tendency toward disinhibited thoughts (Pervasive Influence of Feelings, PIF) and actions (Feelings Trigger Action, FTA) during heightened emotional states, may be particularly relevant. We explored whether Inattention (IN) and Hyperactivity/Impulsivity (HI), two core symptom dimensions of ADHD, would relate to distinct facets of ERI, and whether externalizing and internalizing symptoms would moderate these relations.

Method:

Using structural equation modeling, we examined hypotheses among 364 adults recruited for high internalizing and externalizing symptoms.

Results:

We identified significant paths for FTA regressed on HI and PIF regressed on IN, supporting our hypotheses about main effects. Moderating paths were not significant.

Conclusions:

IN and HI correlate with distinct forms of ERI, These effects appear to generalize across co-occurring internalizing and externalizing symptoms. Theoretical and clinical implications are discussed.
A Review of Selected Dental Anomalies With Histologic Features in the Pediatric Patient
Authors: Schultz Kathleen M. , Penner Carla R.
Published: November 2023

Unique dental conditions in children include odontogenic cysts and tumors, hereditary dental diseases, developmental anomalies, and lesions associated with the eruption of the primary or permanent teeth. Many of these conditions have long lasting effects on the adult dentition in terms of affecting esthetics, function, and overall quality of life. Inherited dental syndromes affect the dental hard tissues specifically the enamel, dentin, and/or cementum in a generalized manner, involving both primary and permanent teeth. These conditions manifest in altered quality or quantity of the hard tissues, leading to fragility, tooth loss and dental diseases such as caries, periapical pathology, and periodontal disease. This category includes amelogenesis imperfecta, dentinogenesis imperfecta, dentin dysplasia, hypophosphatasia, and hypophosphatemia. Developmental defects such as regional odontodysplasia are defined by involvement of the primary and permanent dentition in a localized manner, identified in early childhood. This review will elaborate on the histologic findings in these selected dental conditions with a discussion on clinical and radiographic findings, as well as molecular features wherever appropriate.
A Vector Space Approach for Measuring Relationality and Multidimensionality of Meaning in Large Text Collections
Authors: Poschmann Philipp , Goldenstein Jan , Büchel Sven , Hahn Udo
Published: November 2023

In this article, we develop a methodological approach for organizational research regarding the construction of multidimensional and relational similarity measures by using the vector space model in natural language processing (NLP). Our vector space approach draws on the well-established premise in organizational research that texts provide a window into social reality and allow measuring theory-based constructs ( e.g., organizations’ self-representations). Using a vector space approach allows capturing the multidimensionality of these theory-based constructs and computing relational similarities between organizational entities ( e.g., organizations, their members, and subunits) in social spaces and with their environments, such as the organization itself, industries, or countries. Thus, our methodological approach contributes to the recent trend in organizational research to use the potential inherent in big (textual) data by using NLP. In an example, we provide guidance for organizational scholars by illustrating how they can ensure validity when applying our methodological contribution in concrete research practice.

Background:

Cervical cancer is the fourth most common cancer among women globally, with quality of life (QOL) being a major concern for patients with cervical cancer, especially in low- and middle-income countries (LMICs). This is largely due to the advanced nature of the disease at presentation. Although there are a higher number of studies focusing on the QOL of high-income countries, the QOL of cervical cancer patients in LMICs is not available. The aim of this study is to evaluate QOL among women with cervical cancer in Nigeria using a 2-point assessment.

Methods:

A multi-center prospective cohort study will be conducted in 6 tertiary health facilities randomly selected from the 6 geopolitical zones of Nigeria and consisting of a 2-point assessment of the QOL of participants at the time of diagnosis of cervical cancer and after treatment. Women who were recently diagnosed with histologically confirmed cervical cancer (treatment naïve) will be included. QOL will be assessed using Quality of Life Questionnaire domains (EORTC QLQ30) as developed by the European Organization for Research and Treatment of Cancer (EORTC). In addition to the QOL assessment, relevant and clinicopathological variables will be obtained using a self-structured data extraction sheet designed for this study. All data will be anonymized and will be analyzed using SPSS version 25. Levels of QOL will be calculated using EORTC QLQ30. Ethical approval was obtained from National Health Research Ethics Committee (NHREC/01/01/2007-08/11/2021).

Discussion:

In view of the paucity of data on QOL in LMICs like Nigeria, where most women with cervical cancer present with advanced disease, this research was designed to help in formulating evidence-based interventions to improve the QOL and treatment outcomes provided to women with cervical cancer in Nigeria and other LMICs. The study is expected to fill these knowledge gaps.

The safety and effectiveness of remote guidance of percutaneous coronary interventions (PCI) have not been fully appraised in controlled studies. We hereby presented the results of a study on remote guidance (vs on-site guidance) of PCI to explore its feasibility, safety, and effectiveness. Patients were recruited from those who received PCI procedures from January 2018 to June 2019 in a secondary hospital (Jincheng, Shanxi, China), in collaboration with a tertiary medical center (Beijing, China) approximately 680 km away. According to the type of guidance during the procedure, the patients were assigned to two groups: the remote guidance group and the on-site guidance group. Remote guidance was assisted with an advanced commercial telemedicine system. Interventional strategies, procedural success rate, peri-procedural complications, procedural duration, radiation doses, and the amount of contrast medium were compared between the two groups. A total of 352 patients were included in this study, with a total of 411 PCI procedures and 446 target lesions. The baseline clinical characteristics, as well as the distribution and characteristics of coronary artery lesions, did not differ significantly between the two groups. No significant differences were noticed in procedural success rate, peri-procedural complications, procedural duration, radiation dose, and in-hospital major adverse cardiovascular events. However, the amount of contrast medium was slightly higher in the remote guidance group. The results of the present pilot study showed the feasibility of remotely guided PCI, with safety and effectiveness measures at acceptable levels comparable to the traditional on-site guidance. Randomized studies with long-term follow-up are warranted to further confirm our findings.
Applying data mining techniques to predict vitamin D deficiency in diabetic patients

Published: November 2023

Vitamin D is among the vitamins necessary for both adults’ and children’s health. It plays a significant role in calcium absorption, the immune system, cell proliferation and differentiation, bone protection, skeletal health, rickets, muscle health, heart health, disease pathogenesis and severity, glucose metabolism, glucose intolerance, varying insulin secretion, and diabetes. Because the 25-hydroxyvitamin D (25OHD) test, which is used to measure vitamin D is expensive and may not be covered in healthcare benefits in many countries, this study aims to predict vitamin D deficiency in diabetic patients. The prediction method is based on data mining techniques combined with feature selection by using historical electronic health records. The results were compared with a filter-based feature selection algorithm, namely relief-F. Non-valuable features were eliminated effectively with the relief-F feature selection method without any performance loss in classification. The performances of the methods were evaluated using classification accuracy (ACC), sensitivity, specificity, F1-score, precision, kappa results, and receiver operating characteristic (ROC) curves. The analyses have been conducted on a vitamin D dataset of diabetic patients and the results show that the highest classification accuracy of 97.044% was obtained for the support vector machines (SVM) model using radial kernel that contains 18 features.
