Online Illegal Cryptomarkets
Authors: Haynie Dana L. , Duxbury Scott W.
Published: May 2024

Cryptomarkets—online markets for illegal goods—have revolutionized the illegal drug trade, constituting about 10% of all drug trades and attracting users to a greater variety of and more addictive substances than available in offline drug markets. This review introduces the burgeoning area of sociology research on illegal cryptomarkets, particularly in the realm of drug trade. We emphasize the expanding role of illicit online trade and its relevance for understanding broader exchange challenges encountered in all illegal trade settings. Examining the effects of online illegal trade on consumption and supply-side policing, we also discuss the harm and potential benefits of moving drug exchange from offline to online markets. We argue for a network perspective's efficacy in this research domain, emphasizing its relevance in assessing trade and discussion networks, technical innovation, and market evolution and vulnerabilities. Concluding, we outline future research areas, including market culture, failure, and the impact of online illegal trade on stratification.

Chromatin Condensation Delays Senescence in Human Mesenchymal Stem Cells by Safeguarding Nuclear Damages during In Vitro Expansion
Authors: Joshi Rohit , Suryawanshi Tejas , Mukherjee Sourav , Shukla Shobha , Majumder Abhijit
Published: May 2024

Human mesenchymal stem cells (hMSCs) are multipotent cells that differentiate into adipocytes, chondrocytes, and osteoblasts. Owing to their differentiation potential, hMSCs are among the cells most frequently used for therapeutic applications in tissue engineering and regenerative medicine. However, the number of cells obtained through isolation alone is insufficient for hMSC-based therapies and basic research, which necessitates in vitro expansion. Conventionally, this is often performed on rigid surfaces such as tissue culture plates (TCPs). However, during in vitro expansion, hMSCs lose their proliferative ability and multilineage differentiation potential, rendering them unsuitable for clinical use. Although multiple approaches have been attempted to maintain hMSC stemness during prolonged expansion, finding a suitable culture system remains an unmet need. Recently, a few research groups have shown that hMSCs maintain their stemness over long passages when cultured on soft substrates. In addition, it has been shown that hMSCs cultured on soft substrates have more condensed chromatin and lower levels of histone acetylation compared to those cultured on stiff substrates. Furthermore, it has also been shown that condensing/decondensing chromatin by deacetylation/acetylation can delay replicative senescence in hMSCs during long-term expansion on TCPs. However, the mechanism by which chromatin condensation/decondensation influences nuclear morphology and DNA damage, which are strongly related to the onset of senescence, remains unknown. To answer this question, we cultured hMSCs for long duration in the presence of epigenetic modifiers, histone acetyltransferase inhibitor (HATi), which promotes chromatin condensation by preventing histone acetylation, and histone deacetylase inhibitor (HDACi), which promotes chromatin decondensation, and investigated their effects on various nuclear markers related to senescence. We found that consistent acetylation causes severe nuclear abnormalities, whereas chromatin condensation by deacetylation helps to safeguard the nucleus from damage caused by in vitro expansion.

Published: May 2024

The study was conducted to determine the most suitable soil amendment for germination and early seedling growth of selected indigenous multipurpose agroforestry tree species, viz., Cordia africana, Fiadherbia albida, Millettia ferruginea, and Moringa stenopetala at Haramaya University, Ethiopia. Seedlings were raised in polythene tubes having 10 cm diameter and 15 cm height and the experimental plots were laid out with eight treatments (i.e., potting soil mixture of, A = agricultural soil, M = manure, S = sand, D = DAP, and U = Urea) and three replications. The morphological attributes of seedlings such as shoot and root height, root collar diameter, leaf area were measured to assess tree seedlings vigor and robustness. Analysis of variance indicated that the shoot height of C. africana, F. albida, and M. ferruginea were significantly different (P<0.05) whereas shoot height of M. stenopetala was highly significant (P<0.01). Actual leaf area (cm2) of F. albida and M. stenopetala were significantly different (P<0.05) and estimated leaf area (cm2) of the four species were highly significant at (P<0.01). Treatment 8 (3A: 2M: 1S) for C. africana, treatment 5 (3A: 2M: 1S: 23U) for F. albida and treatment 2 (2A: 2M: 2S: 25D) for both M. stenopetala and M. ferruginea exhibited the lowest sturdiness quotient, which indicates that they are good-quality seedling for plantation. The shoot-to-height ratio indicated positive correlation with most seedling growth parameters whereas root collar diameter and sturdiness quotient showed negative correlation for all species. Treatment 3 (3A: 2M: 1S: 75D) is recommended as the best pot soil mix and fertilization compared to all other treatments, though it needs further study.

Published: May 2024

Someone who could only move his/her head and could not move his/her limbs needs a wheelchair and robotic arms which could be controlled by the head. Gyro sensor is a sensor that could be controlled according to the tilt in the x, y coordinates which then implemented to measure the tilt of the user’s head. This paper would explain the head detector application to control wheelchairs and robotic arms. They could be controlled using Arduino microcontroller which uses C programming language. Gyro sensor that is put on the head could control wheelchair to move left, right, forward, and backward according to the tilt of the head. It is the same with controlling robotic arms. It could rotate left, right, and move up and down. The x and y coordinates are used to determine the tilt of the head for controlling the wheelchair as well as robotic arms’ movements. It is discovered that wheelchairs and robotic arms could be controlled by the head by the use of gyro sensor.

Numerical approach for extraction of photovoltaic generator single-diode model parameters
Authors: Abdelaaziz Benahmida  , Noureddine Maouhoub  , Hassan Sahsah
Published: May 2024

In this work, a numerical approach has been proposed to estimate the five single-diode circuit model physical parameters of photovoltaic generators from their experimental current-voltage characteristics. Linear least square method has been used to solve the system of three linear equations to express the shunt resistance, the saturation current and the photocurrent as a function of the series resistance and the ideality factor. Two key points have been used to solve the system of two nonlinear equations to extract values of series resistance and ideality factor. The advantage of the proposed method with respect of existing numerical techniques is that use only two key points of the experimental characteristic and need only two initial guesses and does not use any approximation. To evaluate the proposed method, three PV generators data have been used to compare the experimental and the theoretical curves. The application of the proposed method provides a good agreement with the experimental.

Authors: Ali K. Nahar  , Mohammed A. Hussein
Published: May 2024

The orthogonal frequency division multiplexing (OFDM)-4G and 5G filter technology suffer a drawback that represents the direction of the peak average to power ratio (PAPR) in orthogonal frequency division multiplexing due to the nonlinear nature of the transmitter. There are a lot of traditional and hybrid methods of these traditional methods to reduce the harmful high PAPR value. Newly, several new hybrid methods have been adopted to reduce PAPR but it faces an increasing level of computational complexity in the system. In this paper, two important and effective conventional methods for reducing PAPR are studied, analyzed, and investigated for the hybrid pathway which is the incorporation of selective mapping (SLM) method and partial transport sequencing (PTS) method, which achieve increased efficiency of PAPR reduction while computing the computational complexity of each method. The method depends and balances with computational complexity. The search is based on multi-carrier connections such as multi carrier-code division multiple access (MC-CDMA) and OFDM.

There is a vast collection of data for consumers due to tremendous development in digital marketing. For their ads or for consumers to validate nearby services which already are upgraded to the dataset systems, consumers are more concerned with the amount of data. Hence there is a void formed between the producer and the client. To fill that void, there is the need for a framework which can facilitate all the needs for query updating of the data. The present systems have some shortcomings by a vast number of information that each time lead to decision tree-based approach. A systematic solution to the automated incorporation of data into a Hadoop distributed file system (HDFS) warehouse (Hadoop file system) includes a data hub server, a generic data charging mechanism and a metadata model. In our model framework, the database would be able to govern the data processing schema. In the future, as a variety of data is archived, the datalake will play a critical role in managing that data. To order to carry out a planned loading function, the setup files immense catalogue move the datahub server together to attach the miscellaneous details dynamically to its schemas.

Published: May 2024

This study investigates the impact of data scaling techniques on the performance of the k-nearest neighbor (KNN) algorithm using ten different datasets from various domains. Three commonly used data scaling techniques, min-max normalization, Z-score, and decimal scaling, are evaluated based on the KNN algorithm's performance in terms of accuracy, precision, recall, F1-score, runtime, and memory usage. The study aims to provide insights into the applicability and effectiveness of different scaling techniques in different contexts, aid in the design and implementation of machine learning systems, and help identify the strengths and weaknesses of each technique and their suitability for specific types of data. The results show that data scaling significantly affects the performance of the KNN algorithm, and the choice of scaling method can have significant implications for practical applications. Moreover, the performance of the three scaling techniques varies across different datasets, suggesting that the choice of scaling technique should be made based on the specific characteristics of the data. Overall, this study provides a comprehensive analysis of the impact of data scaling techniques on the KNN algorithm's performance and can help practitioners and researchers in the machine learning community make informed decisions when designing and implementing machine learning systems.

Published: May 2024

A transition to democratic rule is considered the first step down a long road towards Libya’s recovery and prosperity. Thus, it strives to improve the country’s elections by introducing new technologies. A blockchain is a distributed ledger that is characterised by independence and security. Therefore, it has been widely applied in various fields ranging from credit encryption and digital currency. With the development of internet technology, electronic voting (E-voting) systems have been greatly popularised. However, they suffer from various security threats, which create a sense of distrust among existing systems. Integrating blockchain with online elections is a promising trend, which could lead to make an election transparent, immutable, reliable, and more secure. In this paper, we present a literature review and a case analysis of blockchain technology. Moreover, a framework for an E-voting system based on blockchain is proposed. The methodology is adopted on the basis of three activities, they are identification of the relevant literature about E-voting, system modelling, and the determination of suitable technological tools. The framework is secure and reliable. Thus, it could help increase the number of voters and ensure a high level of participation, as well as facilitate free and fair electoral processes.

Published: May 2024

Achieving success in information system and technology (IS/IT) projects is a complex and multifaceted endeavour that has proven difficult. The literature is replete with project failures, but identifying the critical success factors contributing to favourable outcomes remains challenging. The triad of Time-Cost-Quality is widely accepted as key to achieving project success. While time and cost can be quantified and measured, quality is a more complex construct that requires different metrics and measurement approaches. Utilizing the PRISMA Methodology, this study initiated a comprehensive search across literature databases and identified 142 relevant articles pertaining to the specified keywords. A subset of ten articles was deemed suitable for further examination through rigorous screening and eligibility assessments. Notably, a primary finding indicates that despite recognizing usability as a critical element, there is a tendency to neglect usability enhancements due to time and resource constraints. Regarding the influence of usability on project success, the active involvement of end-users emerges as a pivotal factor. Moreover, fostering the enhancement of Human-Computer Interaction (HCI) knowledge within the development team is essential. Failure to provide good usability can lead to project failure, undermining user satisfaction and adoption of the technology.

Published: May 2024

Background: Non-perforated Polytetrafluoroethylene (PTFE) membranes are effectively utilized in guided bone regeneration (GBR) but may hinder cell migration due to limited interaction with the periosteum. This study compared bone regeneration using occlusive or perforated membranes combined with acellular collagen sponge (ACS) and recombinant human bone morphogenic protein-2 (rhBMP-2) in a canine mandibular model. Material and Methods: Male beagle dogs (n=3) received two mandibular defects each to compare ACS/rhBMP-2 with experimental (perforated group) and control (non-perforated group) membranes (n=3 defects/group). Tissue healing was assessed histomorphologically, histomorphometrically and through volumetric reconstruction using microcomputed tomography. Results: The perforated group showed increased bone formation and reduced soft tissue formation compared to the non-perforated group. For the primary outcome, histomorphometric analysis revealed significantly greater total regenerated bone in the perforated group (67.08 ± 6.86%) relative to the nonperforated group (25.18 ± 22.44%) (p = 0.036). Perforated membranes had less soft tissue infiltration (32.91 ± 6.86%) compared to non-perforated membranes (74.82 ± 22.44%) (p = 0.036). Conclusion: The increased permeability of membranes in the perforated group potentially enabled periosteal precursor cells greater accessibility to rhBMP-2. The availability may have accelerated their differentiation into mature bone-forming cells, contributing to the stimulation of new bone production, relative to the non-perforated group.

Published: May 2024

Background

The EXPLORE (Evaluating Xience and Left Ventricular Function in PCI on Occlusions After STEMI) trial was the first and only randomized trial investigating chronic total occlusion (CTO) percutaneous coronary intervention (PCI) early after primary PCI for ST‐segment–elevation myocardial infarction, compared with medical therapy for the CTO. We performed a 10‐year follow‐up of EXPLORE to investigate long‐term safety and clinical impact of CTO PCI after ST‐segment–elevation myocardial infarction, compared with no‐CTO PCI.

Methods and Results

In EXPLORE, 302 patients post‐ST‐segment–elevation myocardial infarction with concurrent CTO were randomized to CTO PCI within ≈1 week or no‐CTO PCI. We performed an extended clinical follow‐up for the primary end point of major adverse cardiac events, consisting of cardiovascular death, coronary artery bypass grafting, or myocardial infarction. Secondary end points included all‐cause death, angina, and dyspnea. Median follow‐up was 10 years (interquartile range, 8–11 years). The primary end point occurred in 25% of patients with CTO PCI and in 24% of patients with no‐CTO PCI (hazard ratio [HR], 1.11 [95% CI, 0.70–1.76]). Cardiovascular mortality was higher in the CTO PCI group (HR, 2.09 [95% CI, 1.10–2.50]), but all‐cause death was similar (HR, 1.53 [95% CI, 0.93–2.50]). Dyspnea relief was more frequent after CTO PCI (83% versus 65%,
P
=0.005), with no significant difference in angina.

Conclusions

This 10‐year follow‐up of patients post‐ST‐segment–elevation myocardial infarction randomized to CTO PCI or no‐CTO PCI demonstrated no clinical benefit of CTO PCI in major adverse cardiac events or overall mortality. However, CTO PCI was associated with a higher cardiovascular mortality compared with no‐CTO PCI. Our long‐term data support a careful weighing of effective symptom relief against an elevated cardiovascular mortality risk in CTO PCI decisions.

Agreement of Fractional Flow Reserve Estimated by Computed Tomography With Invasively Measured Fractional Flow Reserve: A Systematic Review and Meta‐Analysis
Authors: Faulder Thomas I. , Prematunga Kurundeniya , Moloi Soniah B. , Faulder Lauren E. , Jones Rhondda , Moxon Joseph V.
Published: May 2024

Background

Fractional flow reserve (FFR) is the ratio of blood pressure measured distal to a stenosis and pressure proximal to a stenosis. FFR can be estimated noninvasively using computed tomography (CT) although the usefulness of this technique remains controversial. This meta‐analysis evaluated the agreement of FFR estimated by CT (FFR‐CT) with invasively measured FFR. The study also evaluated the diagnostic accuracy of FFR‐CT, defined as the ability of FFR‐CT to classify lesions as hemodynamically significant (invasive FFR ≤0.8) or insignificant (invasive FFR >0.8).

Methods and Results

Forty‐three studies reporting on 7291 blood vessels from 5236 patients were included. A moderate positive linear relationship between FFR‐CT and invasively measured FFR was observed (Spearman correlation coefficient: 0.67). Agreement between the 2 measures increased as invasively measured FFR values approached 1. The overall diagnostic accuracy, sensitivity and specificity of FFR‐CT were 82.2%, 80.9%, and 83.1%, respectively. Diagnostic accuracy of 90% could be demonstrated for FFR‐CT values >0.90 and <0.49. The diagnostic accuracy of off‐site tools was 79.4% and the diagnostic accuracy of on‐site tools was 84.1%.

Conclusions

The agreement between FFR‐CT and invasive FFR is moderate although agreement is highest in vessels with FFR‐CT >0.9. Diagnostic accuracy varies widely with FFR‐CT value but is above 90% for FFR‐CT values >0.90 and <0.49. Furthermore, on‐site and off‐site tools have similar performance. Ultimately, FFR‐CT may be a useful adjunct to CT coronary angiography as a gatekeeper for invasive coronary angiogram.

Authors: Kruzhkova Olga V. , Vorobyeva Irina V. , Matveeva Alena I. , Zhdanova Natalia E.
Published: May 2024

Background. Modern digital urban environment, as a representation of real urban environment, functions according to the rules of living environment, including its being a real source of stress. The solution of practical tasks to improve the quality of life in the conditions of modern urban environment determine the relevance of research on stress factors of digital urban environment and the study of their possible determinants. Objectives. The study aims to assess the role of personal characteristics of young people, determining subjectively faster reaction to stress factors of digital urban environment. Study Participants. The study involved 619 participants aged from 17 to 25 years (41% males, 59% females), students of colleges and universities of Ekaterinburg. Methods. To study the subjective significance of stress factors of the digital environment, the authors created a specialised questionnaire, which involved the assessment of the 34 proposed stress factors on a scale from 0 to 4 points. The psychodiagnostic techniques HEXACO and “Dark Triad” were used to study personal characteristics of the respondents. Factor analysis, Cronbach's alpha, and linear regression analysis were used to process quantitative data. Results. As a result of factorization, 4 groups of stress factors in the digital urban environment as perceived by young people were identified: imperfection of urban digital services and applications; information coercion and security risks; aggressive behaviour and low culture of interaction of subjects in the Internet; aesthetic unattractiveness of urban digital space. Regression analysis made it possible to build statistically significant models for each of the four identified factors. It was found that the main predictors for sensitivity to stressors of the digital urban environment are negative personality traits. Conclusions. The materials of the conducted research indicate the importance of personality characteristics in determining stress reactions of young people to negative factors of digital urban space, but reflect the variability of their impact on stress: weakening the effect of some types of stressors, but at the same time enhancing the effect of other stressors.

An Efficient Design of a Three-Layer Magnitude Comparator for Nano-Scale IoT Applications Based on QCA Technology
Authors: Chen Hao , Abnoosian Karlo , Salih Mohammed Amin
Published: May 2024

The difficulty of further downscaling CMOS technology arises from the restriction of feature size reduction. Quantum-dot cellular automata (QCA) emerges as a paradigm-shifting successor to CMOS, heralding a new era of effective digital design at the nanoscale. It stands as an enticing
frontier in nanoscale computing, with limited exploration into the realms of smaller QCA cells, elevated processing speeds, and more compact area requirements across diverse circuits. Within the intricate landscape of decoding circuits and process controllers, the binary comparator assumes
a role of paramount significance. On the other hand, the quickly developing Internet of Things (IoT) market aims to produce high-speed, low-power gadgets. A comparator is a crucial component in the analog-to-digital conversion process used by IoT devices. In order to meet the power and latency
requirements of IoT devices, a high-speed, low-power comparator is greatly required. Consequently, the strategic design of comparators within the QCA framework has ascended to a position of heightened importance in cutting-edge research. This study undertakes the formidable task of conceiving
QCA-centric designs for MV32, the majority gate, and the inverter gate, thereby contributing to the development of a sophisticated multi-layered comparator architecture for IoT devices. In the realization of a three-layer comparator implemented in QCA, we attain an impressive feat—a
minimal clock zone demanding only a singular clock pulse coupled with exceptional compaction (measuring at a mere 0.03 μm2). Experimental revelations corroborate the substantial advancement of the proposed design over traditional methodologies, particularly in terms of
circuit area, cell count, and clock efficiency.

The chemical bath deposition approach was used to prepare Cd1−xNixSe thin film photoelectrodes on a substrate made of stainless-steel plate. The constructed cell has the configuration: p-CdNiSe | NaOH (1M)+S (1M)+Na2S (1M) | C (graphite). Studying
current-voltage characteristics in the dark, capacitance–voltage in the dark, barrier-height measurements, power output, photo response, and spectral response are all part of characterizing the photoelectrochemical cell of the photoelectrodes. For the composition of Cd0.7Ni0.3Se,
the junction ideality factor was determined to be minimal. It was discovered that the flat band potential and barrierheight was 710 mV and 0.181 eV respectively. The power output characteristic reveals that, for composition x = 0.3, the short circuit current, open circuit voltage, conversion
efficiency and fill factor are respectively, 161 μA/cm2, 260 mV, 0.64% and 48.11%. The greatest current recorded at 725 nm is displayed in the spectral response.

STC12C5A60S2 single chip microcomputer as the control module, and integrates MAX810 special reset circuit, 2-channel PWM and 8-channel 10-bit A/D converter, thus simplifying the peripheral circuit. During the test, the single chip microcomputer is initialized, the intelligent control part
is embedded with data analysis technology, and the modular debugging method is adopted, and the illumination brightness value meets the expectations under different conditions. The ambient temperature is compared with the test temperature to keep consistent. Based on PWM method, dimming is
carried out, and two environments are set (the first one is to maintain the ambient light illumination of 300lx, and the other one is to maintain the ambient light illumination of 100lx). The results show that the designed system is suitable for different lighting environments and can adjust
the indoor lighting brightness adaptively.
Persistent Severe Headache After Removal of Fungus Ball From the Sphenoid Sinus: A Case Report
Authors: Kim Tae Hoon , Kim SungHee
Published: May 2024

Objective:

Granulomatous invasive fungal sinusitis (GIFS) is a rare and life-threatening disease, whereas fungus ball (FB) is the most common form of noninvasive fungal sinusitis. Both GIFS and FB primarily develop in immunocompetent patients, with the former associated with higher mortality and morbidity.

Methods:

A chart review and review of the literature.

Results:

We present the case of a 77-year-old woman with mixed fungal sinusitis who was successfully treated with voriconazole.

Conclusions:

GIFS and FB can coexist in extremely rare cases, known as mixed fungal sinusitis; however, the diagnosis and subsequent treatment of mixed fungal sinusitis can be delayed because of a lack of awareness of the underlying concept. Therefore, it is crucial for clinicians to recognize the concept of mixed fungal sinusitis.
The genesis of Suket Satyagraha and the birth of Himachal Pradesh
Authors: Thakur Laxman S.
Published: May 2024

This article is primarily based on a study of more than a thousand documents consulted in the Integrated Library of the Tribune Trust, Chandigarh. These documents, largely comprising news items, special reports by staff correspondents or representatives, feature articles, editorials, and letters to the editor, have escaped the attention and scrutiny of researchers and historians of modern Himachal Pradesh. What is fascinating to note is that the word ‘Himachal Pradesh’ was coined at the Solan conclave held during 26–28 January 1948, 2 years before India became a democratic republic; however, Himachal Day is celebrated since 15 April 1948. This article discusses the genesis of and the circumstances that led to the participation of the masses of the Western Himalayan princely states in the Suket Satyagraha, and describes how subsequent events in the ‘Himalayan Prant’ culminated in the creation of what a Tribune correspondent called a new star on India’s firmament—the present-day state of Himachal Pradesh.
Using an Equity-Centered Framework to Guide Family Engagement: Supporting Children’s Lifewide Music-Making through Reciprocal Partnerships
Authors: Culp Mara E. , Grimsby Rachel
Published: May 2024

Engaging families in partnerships that promote student learning and build trust between music educators and the community can be challenging. Therefore, the purpose of this article is to provide suggestions to help music teachers engage families to support children’s lifewide music-making. We share research and scholarship on family musical practices, family composition in the United States, family-inclusive practices, as well as some families’ views of and hopes for music education. We use this literature and an equity-centered framework of family engagement to provide suggestions to build reciprocally beneficial family partnerships, as well as sample materials teachers can use.
Factors Contributing to the Resilience of Sub-Saharan African Widows: A Scoping Review
Authors: Akinduyo Tosin Emmanuel , Theron Linda C.
Published: May 2024

This scoping review aims to synthesize the factors contributing to the resilience of African widows, a topic that has been overlooked. This oversight is concerning, considering the substantial population of African widows, as well as the increasing number of young widows in Africa. We conducted a comprehensive search across various databases (including Academic Search Complete, Africa-wide, PsycARTICLES, PsychINFO, Humanities Sources Worldwide, Proquest, Pubmed, Scopus, Wiley Online, and Taylor & Francis) to identify studies of the resilience of widows living in Africa. From an initial pool of 124 records, we carefully evaluated 19 papers for inclusion. Employing a narrative synthesis approach, we synthesized the findings from the eight selected studies. This analysis revealed that the resilience of African widows is a multifaceted socio-ecological process, primarily facilitated by personal and relational resilience factors. Notably, there is a limited emphasis on the role of cultural resources, which may be attributed to the prevalence of dehumanizing cultural practices experienced by African widows. In conclusion, our findings underscore the need for greater attention to macrosystemic resources, including culturally supportive practices, to bolster the resilience of African widows.
“I Know That Goes Against My Religion”: Explaining Intrafaith Religious Dissent in Latter-Day Saint Views on Abortion with Religious Reflexivity
Authors: Gull Bethany , Cragun Ryan T.
Published: May 2024

While there are a number of studies that note religious individuals do not adhere precisely to the formal doctrines and policies of their faith, few prior studies have attempted to explain why religious individuals dissent from their religion’s official positions. We draw on a religious reflexivity framework with a mixed-methods approach to data collection. The quantitative data is from a survey of Utah residents ( n = 1,909) and provides a rough estimate of the percentage of Mormons who do not hew perfectly to the official position of the religion. The qualitative interviews ( n = 20) illustrate that the members who hold more permissive attitudes toward abortion are aware of their dissent and articulate clear reasons for it. Members who hold more restrictive attitudes appear to be unaware that their views are more extreme than their religion’s teachings. Yet, both more and less restrictive groups tend to use their religion’s teachings—interpreted through varied moral systems—to justify their dissent.
Robust profiled carbon rovings made of multiple yarns for textile reinforcements in concrete and asphalt matrix

Published: May 2024

The load-bearing behavior and the performance of composites depends largely on the bond between the individual components. Conventional grid-like textile reinforcement structures with thin and smooth yarn structures transmit forces primarily by an adhesive bond with the surrounding matrix. A sufficient load transmission is not possible. Thick, pultruded rebars made of fiber-reinforced plastics can be profiled by subtractive (e.g. milling) or additive (e.g. wrapping) techniques in order to create a rip-like structure and increased shear bond. Yet the discontinuous fiber course results in material inefficiency. A newly developed profiling technique allows a tetrahedral profiling of the complete roving structure, yet considering its anisotropic properties. In the article, we present this approach, and the first results from single yarn tensile and pull-out tests of single, double and triple plied profiled rovings in concrete and asphalt matrix. Thus, the highest bond is achieved in the brittle concrete matrix. Plied rovings with strong tetrahedral profiles show up to 600% higher bond stress compared with rovings with circular profiles, while maintaining high tensile properties. However, splitting-induced failure of the reinforced test specimens occurs, making plied profiled rovings favorable for high concrete cover and less brittle matrixes; for example, asphalt. The reinforced asphalt specimens show at −10°C similar bond properties, but at 30°C the bond decreases by 80%. In summary, the study shows that bond properties of profiled rovings are superior to conventional circular rovings, and promise a high material efficiency for use in concrete and asphalt reinforcements.

Authors: Haunstrup Jørgen Skovhus
Published: May 2024

Public leadership is increasingly conducted through digital information technology, and dynamic leadership tools are offered as alternatives to static tools. As a first test of dynamic leadership tools in public leadership, this study focuses on leadership tools for visionary leadership. The study examines whether the positive effect on employee needs satisfaction of dynamic leadership tools based on persuasive information technology is stronger than for static leadership tools. The study involves a field experiment on leadership training combined with leadership tools and shows that dynamic tools indeed have a stronger impact than static tools on satisfying employee needs for meaning and employee perception of prosocial impact. This research contributes to the understanding of how information technology can be harnessed to support public leadership and highlights the potential benefits of dynamic leadership tools in supporting beneficial employee outcomes.
Experiential learning in the master of public administration classroom: An application of the family-friendly campus toolkit
Authors: Idika-Kalu Cecilia , Smith-Walter Aaron , Vinson Jenna
Published: May 2024

Public administrators can play a vital role in the articulation of demands emerging from the community and can serve to advance these demands by their position of authority, skills and knowledge to help facilitate the development of programs and projects to address public needs. This article describes the role that a small Master of Public Administration program and several of its faculty and students played to support a project which sought to aid the development of family-friendly policies and programs on the campus of the University of Massachusetts Lowell, a mid-sized, public university in the Northeastern United States. The article lays out the personal experience of the authors as they relate to their decision to participate in the program, a description of the project and the assistance that MPA students were able to render the initiative, the manner in which integrating the commitment to campus improvement for pregnant and parenting students influenced the content of several MPA courses, and the synergies which developed as students worked to develop skills in communication, focus-group moderation, qualitative data analysis, presentation delivery and report-writing.
