A Conceptual Model of Trust, Perceived Risk, and Reliance on AI Decision Aids

There is increasing interest in the use of artificial intelligence (AI) to improve organizational decision-making. However, research indicates that people’s trust in and choice to rely on “AI decision aids” can be tenuous. In the present paper, we connect research on trust in AI with Mayer, Davis, and Schoorman’s (1995) model of organizational trust to elaborate a conceptual model of trust, perceived risk, and reliance on AI decision aids at work. Drawing from the trust in technology, trust in automation, and decision support systems literatures, we redefine central concepts in Mayer et al.’s (1995) model, expand the model to include new, relevant constructs (like perceived control over an AI decision aid), and refine propositions about the relationships expected in this context. The conceptual model put forward presents a framework that can help researchers studying trust in and reliance on AI decision aids develop their research models, build systematically on each other’s research, and contribute to a more cohesive understanding of the phenomenon. Our paper concludes with five next steps to take research on the topic forward.
Development of an Equivalent Circuit Model for the Design of Arrays of Electrically Small Antennas

In this paper, we present a fully parameterized circuit model of an array antenna that relates antenna performance and field coupling to the physical parameters of the elements as represented through a circuit model. We demonstrate that the simplified model can be used as a surrogate for full-wave modeling during the initial optimization steps in array design. The model accounts for mutual coupling between array elements both through the feeding network and through free space. We present a method to calculate the mutual coupling between elements in the array antenna that is parameterized in terms of the size and location of the individual elements, and these circuit models provide excellent agreement with the scattering parameters calculated by the full-wave numerical model. The model is applied to the analysis of a specific built array configuration, and we demonstrate that the simplified circuit model can have strong predictive effects for designing arrays of electrically small antennas and predicting their ultimate performance by comparing with numerical and limited experimental measurements. The study is motivated by high power electromagnetic applications, where arrays of densely space elements can help reduce the antenna size necessary to radiate extremely large power signals.
Near Infrared LEDs-Based Non-Invasive Blood Sugar Testing for Detecting Blood Sugar Levels on Diabetic Care

Diabetes Mellitus, with its rapid development and various complications that have caused it, has become one of the deadliest diseases in the world. Early detection efforts to raise blood sugar levels can help to avoid a variety of complications. Measuring devices are needed to find out blood sugar levels detect how much sugar is in the blood. The blood sugar measuring device is invasive by taking blood from capillaries tested both in the lab and using portable testing instruments. The use of this tool results in discomfort, pain, and trauma for the patient. The purpose of this study was to determine the degree of sensitivity of the NIR LED sensor on the thumb to the little finger to the reading of light reflections coming out of body tissues. Currently, the index finger is often used as a medium to find out how much blood sugar is in non-invasive blood sugar measurements. The other four fingers' sensitivity is unknown at this time. Because the use of the index finger, which is located in the middle, can make activities difficult at times, information on the sensitivity level of the other fingers is required. This paper discusses the sensitivity of placing the NIR LED sensor on the five fingers to determine the most sensitive finger with the best response. Based on the testing results of 15 samples, Although the index finger receives the most significant stress, the correlation and linear regression tests show that the thumb has the closest relationship with the R2 = 0.6841. With this research, a test instrument with higher sensitivity for Diabetes can be developed by placing the sensor in a comfortable area. The implication is that the results of this study can be recommended to use the thumb as an alternative to the placement of the NIR LED sensor to measure blood sugar levels non-invasively in DM patients.
Prognostic Factors in Patients with Breast Cancer Liver Metastases Undergoing Liver Resection: Systematic Review and Meta-Analysis

Simple Summary Robust predictive and prognostic tools are needed in the management of breast cancer liver metastases (BCLMs). Until now, surgery has not been the gold standard of treatment of patients with BCLMs. The present manuscript highlights several predictive factors related to the primary tumor and the BCLM that may help to identify candidates for surgery with favorable outcomes in a large cohort of patients. Abstract Background: The role of surgical resection of liver metastases in patients with breast cancer liver metastasis (BCLM) remains controversial. A systematic review and meta-analysis of prognostic factors related to survival after BCLM resection was performed. Methods: An electronic search of relevant publications was performed. Pooled outcome measures were expressed as hazard ratios (HRs), including 95% confidence interval values (95% CIs), and calculated through a random-effects model. Heterogeneity was tested through the I2 index. Results: Thirty-five publications reported analyses on prognostic factors and survival. A total of 2782 patients who underwent liver resection for BCLM were included. Positive axillary lymph nodes at breast cancer diagnosis were an unfavorable survival factor (HR 1.74, 95% CI 1.25 to 2.41, I2 = 0%). Cumulative predictive factor HRs (multiple liver metastases, size of the metastases, short interval between primary tumor and onset of liver disease) related to the BCLM pattern were 1.32 (95% CI 1.17 to 1.48, I2 = 71%) and 1.51 (95% CI 1.15 to 1.98, I2 = 76%) for surgical and pathological features (resection margin and presence of extrahepatic disease), respectively. Conclusion: Resection of BCLM may provide a survival benefit for selected patients. For better long-term results, surgical selection should consider both primary tumor and BCLM features such as negative axillary lymph nodes at breast resection, a single hepatic lesion, a time longer than 24 months between breast and hepatic diagnosis, and a realizable R0 liver resection. However, the high heterogeneity among studies suggests the need for an RCT to validate the present findings.
Does Entry Remedy Collusion? Evidence from the Generic Prescription Drug Cartel

Entry represents a fundamental threat to cartels engaged in price fixing. Starc and Wollmann study the extent and effect of this behavior in the largest price fixing case in US history, which involves generic drugmakers. To do so, the researchers link information on the cartel’s internal operations to regulatory filings and market data. They find that collusion induces significant entry, which in turn reduces prices. However, regulatory approvals delay most entrants by 2-4 years. They then estimate a structural model to assess counterfactual policies. The authors find that reducing regulatory delays by just 1-2 years equates to consumer compensating variation of $597 million-$1.52 billion.
Assessing Prevalence and Transmission Rates of Malaria through Simultaneous Profiling of Antibody Responses against Plasmodium and Anopheles Antigens

Reliably assessing exposure to mosquitoes carrying malaria parasites continues to be a challenge due to the lack of reliable, highly sensitive diagnostics with high-throughput potential. Here, we describe an approach that meets these requirements by simultaneously measuring immune responses to both disease vector and pathogen, using an electro-chemiluminescence-based multiplex assay platform. While using the same logistical steps as a classic ELISA, this platform allows for the multiplexing of up to ten antigens in a single well. This simple, reproducible, quantitative readout reports the magnitude, incidence, and prevalence of malaria infections in residents of malaria-endemic areas. By reporting exposure to both insect vectors and pathogen, the approach also provides insights into the efficacy of drugs and/or other countermeasures deployed against insect vectors aimed at reducing or eliminating arthropod-borne diseases. The high throughput of the assay enables the quick and efficient screening of sera from individuals for exposure to Plasmodium even if they are taking drug prophylaxis. We applied this assay to samples collected from controlled malaria infection studies, as well as those collected in field studies in malaria-endemic regions in Uganda and Kenya. The assay was sensitive to vector exposure, malaria infection, and endemicity, demonstrating its potential for use in malaria serosurveillance.
Determination of stature from hand dimensions

Background: Due to increase events of mass disaster and brutal murders, dismembered body parts are sent to postmortem examination every now and then. Determination of stature from dismembered body parts can play vital role for identification of person. This study can be helpful there to determine stature from Hand length and Hand breadth. Aims and Objectives: To derive Regression formula and multiplication factor to determine stature from Hand length and Hand breadth for population in and around Rajkot region of Gujarat. Study Design: Cross Sectional Study. Materials and Methods: This study was carried out on 100 male cases and 100 female cases randomly selected from cadavers brought for post-mortem examination at mortuary of P. D. U. Govt. Medical College and Hospital, Rajkot. Stature was measured with measuring tape and Hand dimensions were measured by Sliding caliper after breaking Rigor mortis, if developed. Statistics: Collected data were statistically analysed using software like Epi info 7 and Microsoft excel. Results: Hand length and Hand breadth of right as well as left sides were positively and significantly correlated to stature (r ranging from 0.423 to 0.639, p<0.001). No significant difference was observed in Hand length of both sides (p>0.05), however Hand breadth of right side wassignificantly higher than left side (p<0.05). Stature, Hand length and Hand breadth of male were significantly greater than of female (p<0.05). Regression formula were showing standard error of estimate (SEE) ranging from ±4.70 to ±5.99. Hand length was showing less SEE than Hand breadth, making it more useful for determination of stature. Conclusion: Hand length and Hand breadth are showing good correlation with stature. It was found from the study that regression formula can measure stature more precisely than multiplication factor, moreover regression formula derived from Hand length predicts stature more accurately than from Hand breadth. Regression formula and multiplication factor derived by present study for population in and around Rajkot region can be used for identification purpose in medico-legal cases.
Impact of Workplace Spirituality on Organizational Commitment with the Mediating Role of Organizational Culture

The importance of Workplace spirituality is gaining fame among scholars. In the recent past, management’s scholars have successfully found its affiliation with different variables. The aim of this study is to add knowledge in literature and provide suggestion for practical implementation, regarding the subject. All the results are based on empirical analysis of the data collected in Higher Education Institutions of Pakistan. The study investigated the causal affiliation between workplace spirituality and organizational commitment of faculty members with the mediating variable of organizational culture. Research was conducted in the public sector universities of Khyber Pakhtunkhwa, Pakistan. Four universities were selected randomly out of 29 universities. Questionnaire was used for the collection of data with 7-point Likert scale. Two hundred questionnaires were distributed among the selected universities out of which one hundred and ninety questionnaires were received. The study used Barron and Kenny’s method and hypothesis were confirmed with multiple regression analysis. Results indicate that workplace spirituality (WPS) has positive and significant association with organizational culture and the later significantly mediates the impact of WPS on organizational commitment. Those employees who are spiritually motivated coupled with a positive organizational culture leads to enhanced commitment of employee.
Workplace relationships in Europe: An analysis by occupation and employment status

Purpose: This article analyses the extent to which two objective attributes of work – employment status, and occupation – influence workplace relationships in Europe. Employing a quantitative and transnational approach, we explore how far the segmentation of the labour market is reflected in the non-material dimensions of working life, seeing the nature of work and the stabilisation of employment as resources that help explain broader dynamics of job quality.Design/methodology/approach: Based on three indicators from the European Working Conditions Survey (support from colleagues; support from managers; and the quality of relationships), we performed a two-way ANOVA to test both the primary effects of the variables ‘employment status’ and ‘occupation’ on support and quality of workplace relationships, and their interaction effect. Additionally, we carried out a descriptive analysis of the mean scores of each of the dependent variables in the various groups of the independent variables.Findings: The results show that workers with more stable jobs, and those who occupy positions at the top of the occupational hierarchy, enjoy more support and better interpersonal relationships, thus suggesting the need to extend labour market segmentation discussions to the relational spheres of work.Research limitations/implications: The statistical indicators used need a more robust operationalisation, able to provide greater empirical validity. Other independent variables, such as the perceptions of job security or the country of work should be considered in future analysis to control for institutional and policy specificities.Originality/value: Research on workplace relationships tends to emphasise the effects that such relationships have on both organisations and individuals, usually based on case studies and individual narratives of relationships formed in stable work contexts. In this article, we shift the focus from the effects of workplace relationships, to the ways in which they vary in accordance with the nature of work and the objective employment conditions.
The topological arrangements of Nijmegen’s ‘Walk of the World’: from a military march to ‘martial entrepreneurialism’

ABSTRACT Since 1916, the Dutch city of Nijmegen annually organizes the Four-Day Marches, the world’s largest international walking event, shaping the city along the way. This paper studies the ‘coeval becoming’ of the March and city through the lens of ‘glocal’ topological arrangements, drawing on a ‘wheeling’ racialized assemblage perspective. This wheeling, we argue, scripts Nijmegen and its March through four topological arrangements: Nijmegen as Host, Nijmegen as Global Node, Nijmegen as Haunted Body, and Nijmegen as Empty Green. In conclusion, we find a strong emphasis on able-bodies and branding, yielding a characterization of ‘martial entrepreneurialism’.
Effects of Nature-Based Intervention in Occupational Health Care on Stress – A Finnish Pilot Study Comparing Stress Evaluation Methods

Purpose To assess methodology and its limitations for measuring effects of nature-based intervention (NBI). Patients and Methods Participants were 11 middle-aged female health care workers with lowered capacity to work. NBI included six group appointments in six months study period. Heart rate variability (HRV) and self-reported pain and work exhaustion were measured pre-post study period. Salivary α-amylase samples were collected immediately before and after three individual interventions. Salivary cortisol samples were collected on the same three interventions, on three consecutive days starting from the day of intervention, to assess (a) month effect (pre-post study period) and (b) day effect (intervention day vs non-intervention day). Results Individual interventions resulted in increase in α-amylase activity. However, the average fold increase decreased from the 3.05 ± 1.20 of the first intervention to 1.91 ± 1.00 and 1.46 ± 0.77 in the second and third intervention, respectively (p < 0.001). Cortisol concentrations were lower on intervention days vs non-intervention days, the difference being indicative (p = 0.050). Pain and work exhaustion decreased during the study period, as well as HRV, although any of these changes was not statistically significant. Conclusion For a large-scale study, it would be ideal to select assays for both major pathways: hypothalamic-pituitary-adrenal axis can be measured by cortisol, whereas response via autonomic nervous system can be measured by HRV, when roles of sympathetic and parasympathetic nervous systems can be pinpointed separately. Salivary α-amylase can be used when continuous monitoring is not possible. Psychological well-being of participants should be surveyed, as well as their activities and moods on sampling days recorded.
Ethics Position of Brazilian Workers: An International Comparative View

Abstract This article explores Brazilian workers’ ethics position and compares it to those of other nations. We surveyed 410 Brazilian workers and used the Ethics Position Questionnaire (EPQ), with idealism and relativism scales. We translated, back-translated, and adapted the scales according to Sperber and conducted exploratory factor analyses together with confirmatory factor analyses to validate them. The results show that Brazilians present, on average, high idealism and low relativism. Therefore, Brazil appears to be a well-defined “absolutist” country compared to other nations, a surprising outcome, since Brazil ranks as one of the most corrupt countries on international scales.
Neuropharmacological and Antidiabetic Potential of Lannea coromandelica (Houtt.) Merr. Leaves Extract: An Experimental Analysis

The present study examines the neuropharmacological and antidiabetic properties of methanol leaves extract of Lannea coromandelica in animal models. This study is carried out by elevated plus-maze apparatus, motor coordination, thiopental sodium has an induction role in sleeping time, hole board, hole cross, open field, antidiabetic studies. Mice were treated doses of 100, 150, and 200 mg/kg body weight in elevated plus-maze apparatus and motor coordination; 100 and 200 mg/kg body weight in sleeping time, hole cross, hole board, and open field tests; and 200 and 400 mg/kg body weight in the antidiabetic activity test. Extraction specifies a significantly decreased time duration and sleeping time in a thiopental sodium-induced sleeping time test. The experimental extract decreased locomotor and exploratory behaviors of mice in the open-field and hole-cross tests compared to the effects of the control. Furthermore, the extract increased sleeping time with a dose-dependent onset of action. The hole-board test extract also demonstrated a reduced number of head dips. The findings showed that L. coromandelica has potential neuropharmacological effects. In addition, in alloxan-induced diabetic mice, leaves extract at 200 and 400 mg/kg body weight revealed significant antidiabetic properties and could be used to manage blood glucose levels with more research.
Infective Endocarditis by Moraxella Species: A Systematic Review

Moraxella catarrhalis is the most clinically relevant species among Moraxella spp. For decades, it was considered to be part of the normal human flora in the upper respiratory tract. However, since the late 1970s, considerable evidence has proposed that M. catarrhalis is an important pathogen in the human respiratory tract. Even though Infective Endocarditis (IE) is rarely caused by Moraxella spp. , these infections can be problematic due to the lack of experience in their management. The aim of this study was to systematically review all published cases of IE by Moraxella spp. A systematic review of PubMed, Scopus and Cochrane library (through 8 December 2021) for studies providing epidemiological, clinical, microbiological data as well as treatment data and outcomes of IE by Moraxella spp. was performed. A total of 27 studies, containing data for 31 patients, were included. A prosthetic valve was present in 25.8%. Mitral valve was the most commonly infected site. Fever, sepsis and embolic phenomena were the most common clinical presentations. Cephalosporins, aminoglycosides, aminopenicillins and penicillin were the most commonly used antimicrobials. Overall mortality was 12.9%.
National Culture Moderators of Pay for Individual Performance and the Financial Performance of Multinational Enterprises

We examined the effectiveness of pay for individual performance (PFIP) in companies operating in multiple cultures. With the use of data from 308 multinational enterprises (MNEs) collected by IBM's WorkTrends ™ project, we tested hypotheses regarding the moderating influence of the nine dimensions of the GLOBE country culture model on the relationship between PFIP and changes in financial performance over time. Multiple employees per firm (mean N = 24.7 employees) reported the extent there was a PFIP climate (PFIPc) in their firm. We matched these data at the firm level to changes in net income per employee over 4 years from the Wharton Research Data Service (WRDS). Consistent with predictions developed from contingency and cross-cultural theories, after including relevant controls, we found the positive relationship between PFIPc and subsequent MNE performance is greater in cultures higher in future orientation, institutional collectivism and uncertainty avoidance and also lower in in-group collectivism, power distance and humane orientation.
Effect of aging time on microstructural and mechanical properties of 6061 aluminum alloy

Aluminum alloy 6061 have moderate strength, good formability, and excellent corrosion resistance, it has a wide use in several engineering sectors. Age hardening is the main feature of this alloy. In this study, some mechanical characteristics of Aluminum 6061 samples aged to different times has been studied. The specimen’s mechanical properties were improved in general; best mechanical properties were achieved after 2 hours of heat treatment at 200oC. Ultimate tensile stress, yield stress, ductility and microhardness variation with aging time are discussed regarding to the microstructural alteration caused by heat treatment. We found that the Mg2Si initiation and growth was a function for aging time, which was the main cause for improvement of the alloy mechanical features.
