Project management and circular economy in agribusiness: A systematic literature review
Authors: Dalto José Luis , Silva Luciano Ferreira da , Penha Renato , Bizarrias Flavio Santino
Published: December 2023

This article aims to identify how project management can enable the introduction of circular economy (CE) in agribusiness. The methodological strategy used was the systematic literature review. The research corpus consisted of 70 articles selected from the Web of Science and Scopus databases. For screening, the Rayyan platform was used, and the analysis process was carried out by categorization and grouping of terms and concepts with the help of Excel software. The evidence shown the efforts to reduce agro-waste and how to transform them into by-products. Barriers, challenges, benefits and opportunities for making the CE viable in agribusiness are presented. Three ways of projecting the CE in agribusiness are identified: (1) project management processes in the integration of the CE in agribusiness, (2) innovative projects and new business models as drivers of the CE in agribusiness and (3) 4.0 technologies integrating the CE in agribusiness based on project management methodologies. Results are limited to terms used in search mechanisms. This research contributes towards identifying project management processes that can enable the CE in agribusiness, particularly by identifying the impacts of the CE in different business areas. The research also contributes in a practical way by providing insights on ways to make the CE viable in agribusiness through project management.
Process and Content in Performance Management: How Consistency and Supervisor Developmental Feedback Decrease Emotional Exhaustion Via High-Quality LMX
Authors: Van Strydonck Isabeau , Decramer Adelien , Peccei Riccardo , Audenaert Mieke
Published: December 2023

Performance Management (PM) is often criticized for undermining employee emotional exhaustion. To avoid such unintended consequences, this study investigates how PM can be of benefit to employee emotional exhaustion by integrating both process and content aspects of PM. Results show that a consistent PM process, in which the same performance expectations are maintained across the different practices of performance planning, monitoring, and evaluation, is negatively related to employees’ emotional exhaustion, indirectly via the development of high-quality Leader-Member Exchange (LMX) relationships. Second, we found that, in terms of the content, supervisor developmental feedback acts as a moderator, determining the need to implement PM as a consistent process. A consistent PM process was especially important when the feedback provided throughout the PM process involved a lesser developmental content. When employees already received a large amount of developmental feedback, the degree to which the PM process was characterized by consistency made no difference to outcomes.
Situational Orders: Interaction Patterns and the Standards for Evaluating Public Discourse
Authors: Marom Oded
Published: December 2023

How do civic groups judge what issues are appropriate for public discourse? And how do they know what kinds of arguments to use where? Cultural sociologists identify varying “orders of worth,” that is, historically defined systems of typification and evaluation people draw on to evaluate public arguments. Yet it remains unclear how these take form in ongoing group practices. This article theorizes how groups’ ongoing interaction patterns, or “style,” typify social scenes to steer members toward distinct orders of worth in varying situations. As I argue, different typifications of public and private scenes condition the type of arguments members deem appropriate for public discourse, with meaningful implications for their politics. Combining style and orders of worth allows us to ask how ostensibly similar groups may publicly define different political goals and value varying forms of civic engagement. I illustrate this theoretical framework with an ethnographic study of two culturally distinct groups of libertarians in the United States.
The link between gender discrimination and work satisfaction between female journalists in Chile: Comparing data from 2016 and 2022
Authors: Leiva Ricardo , Riveros Alejandra
Published: December 2023

We conducted two surveys (in 2016 and 2022) to measure the work satisfaction of Chilean female journalists and applied a face-to-face version of the questionnaire to 146 male journalists. Conducting t-tests to compare means, we found that during these 6 years, work satisfaction by Chilean female journalists decreased soundly and was significantly smaller than that of male journalists. We also found that female journalists are more willing than men to quote sources of their gender and feature them as newsmakers in the news media. Conducting a regression analysis, we found that three independent variables were highly significant as they had a clear effect on the work satisfaction declared by female journalists. They were “perceived autonomy,” “gender equality at work” “and having enough female editors or supervisors in their newsrooms.” On the contrary, annual wage, work promotion, marital status, age and job status did not appear as relevant variables for women to assess their work satisfaction. Our results confirm that women are more satisfied when they work in an equal workplace, with a low perception of gender discrimination and having enough female editors or supervisors in their newsrooms.

Published: December 2023

Adults’ ability to accurately evaluate children’s statements can have far-reaching consequences within the legal system. This study examined the evaluations of police officers (“experts”) and laypersons (“nonexperts”) when presented with videotaped interviews of children aged 3 and 5 years who provided either true or false reports or denials. Participants were drawn from several counties in the eastern United States. Children’s interview statements fell within four statement types: accurate reports, false reports, accurate denials, and false denials. Both groups of participants displayed overbelief in false denials. Several control variables predicted accuracy, including children’s age and children’s race. A significant interaction emerged: Experts (vs. nonexperts) had greater odds of being accurate when judging false reports (vs. false denials). These findings highlight the challenges adults face when distinguishing between various types of children’s statements. The results have important implications for legal contexts, emphasizing that fact finders need to be mindful of the risks associated with both overaccepting false denials and accepting false reports.
Patterns of Avoidance Behavior in Response to Fear of Victimization in the Mexican Context: A Latent Class Analysis
Authors: Borja Sharon , Storer Heather , De La Cruz Pedro Isnardo , Mark Eddy J.
Published: December 2023

Fear of victimization (FOV) is a powerful determinant of behavior and prompts behavioral responses such as avoidance, associated with a decline in health-promoting activities and quality of life. Avoidance behaviors, which include constraining activities to perceived safe areas and avoiding areas regarded as unsafe, are of particular interest due to their high prevalence as a coping response to FOV and their link to adverse physical and mental health. Most research on FOV-related avoidance treats it as a single construct and have yet to elucidate the potential heterogeneity within this set of behaviors. We argue that such approach could mask potential heterogeneity among people who respond to FOV through avoidance and how they adapt to manage perceived risk. Our analysis extends the foundational knowledge regarding FOV-related avoidance using a person-centered approach. We attempted to capture distinct profiles across avoidance behaviors and how they are shaped by physical and social vulnerabilities. Data from the 2021 Mexico’s National Survey of Victimization and Perception of Security Survey ( n = 83,696) was analyzed using Latent Class Analysis focusing on 15 avoidance behaviors (e.g., stopped using public transportation). We conducted multinomial logistic regression to test whether age, gender, education, and neighborhood deprivation significantly predicted class membership. Findings revealed three classes: avoidant (most behavioral adjustments across the board), cautious (only adapted some behaviors), and protective (least behavioral adjustments, but more concerned about minors in their households). The results supported the hypothesized associations between age, gender, education, and neighborhood deprivation with group membership, but the significance differed by group. This research underscores the role of environmental context in shaping individual perceptions of safety and avoidance behavior. Finally, contrary to the approach of treating avoidance behavior as a single category, these findings present a more complex picture as distinct and meaningful patterns emerged across the three groups.

Published: December 2023

Depressive symptoms and delinquent behaviors that emerge during adolescence pose both short- and long-term negative outcomes. Though there is growing evidence that exposure to teen dating violence is also associated with a greater likelihood of depressive symptoms and delinquent behaviors such as engaging in peer violence and substance use, less is known about the effects of specific forms of electronic dating violence (i.e., electronic harassment, electronic coercion, and electronic monitoring) across adolescence on depressive symptoms and delinquent behaviors. Data were drawn from a 4-year prospective longitudinal study of two cohorts of youth followed from age 12 to 15 ( n = 526, 52% female) and age 15 to 18 ( n = 592, 53% female). Two mixed-effects models (stratified by cohort) were employed to evaluate depressive symptoms and delinquent behavior outcomes by exposure to electronic harassment, electronic coercion, and electronic monitoring, while accounting for verbal dating violence, physical dating violence, sexual dating violence, exposure to threat-based adverse childhood experiences, exposure to deprivation-based adverse childhood experiences, and gender across all four waves of data collection. Higher exposure to electronic sexual coercion was predictive of increased depression (β = .015, p = .018). Increased exposure to electronic sexual coercion (β = .007, p = .004) and electronic monitoring (β = .008, p = .045) were both predictive of more delinquency across adolescence. By delineating the effects of in-person verbal, physical, and sexual dating violence with unique electronic domains, we found unique additional risk from domains of electronic dating violence, which was particularly pronounced for youth who reported electronic sexual coercion. Electronic sexual coercion heightens the risk of depressive symptoms and delinquent behaviors in males and females beyond the risk presented by in-person forms of dating violence and should be accounted for in prevention and intervention programs. Future research should explore the effect of perceived normativity on the prevalence of electronic harassment and subsequent influence on outcomes.

Published: December 2023

Background:

Although many mothers initiate breastfeeding, supplementation with human-milk substitutes (formula) during the birth hospitalization is common and has been associated with early breastfeeding cessation. Colostrum hand expressed in the last few weeks before birth, known as antenatal colostrum expression (ACE), can be used instead of human-milk substitutes. However, evidence is lacking on the efficacy of ACE on breastfeeding outcomes and in non-diabetic mothers.

Methods and Planned Analysis:

This multicenter stepped-wedge cluster (nested) randomized controlled trial aims to recruit 945 nulliparous pregnant individuals. The trial is conducted in two phases. During Phase 1, control group participants are under standard care. During Phase 2, participants are randomized to ACE instruction via a pre-recorded online video or a one-on-one session with a midwife. Adjusted logistic regression analysis will be used to examine the relationship between ACE instruction and breastfeeding outcomes.

Research Aims and Questions:

Primary aim: (1) Does advising pregnant individuals to practice ACE and providing instruction improve exclusive breastfeeding rates at 4 months postpartum? Secondary research questions: (2) Do individuals who practice ACE have higher rates of exclusive breastfeeding during the initial hospital stay after birth? (3) Is teaching ACE via an online video non-inferior to one-on-one instruction from a midwife? (4) Does expressing colostrum in pregnancy influence time to secretory activation, or (5) result in any differences in the composition of postnatal colostrum?

Discussion:

Trial findings have important implications for maternity practice, with the online video providing an easily accessible opportunity for ACE education as part of standard antenatal care.
The Climate Crisis and Breastfeeding: Opportunities for Resilience
Authors: Cerceo Elizabeth , Saxer Karen , Grossman Lauren , Shapley-Quinn Kathleen , Feldman-Winter Lori
Published: December 2023

The climate crisis is an emerging global challenge that poses potential risks to breastfeeding practices and outcomes. There are multifaceted effects of climate change affecting the breastfeeding dyad across environmental, societal, and human health dimensions. Breastfeeding support in the face of climate change will require solutions at the structural level—healthcare, community, and workplace settings—and at the mother-infant dyad level. Breastfeeding can additionally be an adaptive response to crisis situations and can mitigate some of the environmental challenges associated with climate change. Despite the undeniable significance of climate change on breastfeeding (and vice versa), our perspective as experts in the field is that this topic has not been systematically addressed. Although we highlight some of the challenges, potential solutions, and co-benefits of breastfeeding in the context of climate change, there are numerous issues that could be further explored and necessitate additional preparedness planning.
Analytical model of low-velocity impact penetration of sandwich panels with metal foam core and nanocomposite face sheets
Authors: Bahrami Mohammad Amin , Feli Saeed
Published: December 2023

This paper investigates the low-velocity penetration dynamic response of metal foam core sandwich panels with composite face sheets reinforced by nanoparticles. Based on the experimental results, an energy model is developed to predict contact force, impactor displacement, energy absorption, mechanisms of impact damage, and failure modes. An elastic–plastic–rigid (E–P–R) model is used to derive the energy absorbed by the metal foam. A stress function in terms of density ratio and strain is considered to predict the compression behavior of metal foam. The effect of nanoparticles investigated by the Halpin Tsai model. The analytical prediction is compared with the results of the experimental test and a reasonable agreement has been observed. The tested sandwich panel consisted of an aluminum foam core and an epoxy/carbon fiber face sheet reinforced with reduced graphene oxide (RGO). This model is useful for improving the design of sandwich panels with carbon fiber composite face sheet reinforced with nanoparticles and aluminum foam core. The results of impact test showed the addition of reduced oxide graphene increased the value of the first peak load by about 15%, the second peak load by about 36% and the amount of energy absorption in sandwich panel by about 18%. The radios of delamination and debonding reduced by 47% and 17.5%, respectively, compared to the sample without nanoparticles.
Research on error compensation method of topography dynamic reconstruction of chattering thin-walled parts based on structured light detection
Authors: Li Maoyue , Lv Hongyu , Liu Shuo , Liu Zelong , Zhang Minglei
Published: December 2023

In order to achieve visual measurement error compensation for the surface of thin-walled components with chatter, a new real-time adaptive correction method for chatter motion error is proposed in this paper. Firstly, according to the mechanism of the chatter effect, an error analysis model of the dynamic structured light phase principal value is derived. Then, a real-time optimization method for the motion phase error in the frame of structured light projection is proposed. Meanwhile, a compensation method based on an adaptive grating projection period is proposed to eliminate the cumulative error of inter-frame chatter motion. Finally, a structured light visual inspection system and an experimental platform for chattering thin-walled parts are established for experimental verification. The experimental results under slight and severe chatter conditions indicate that the proposed method can optimize the phase errors within the projected frame in real time under any scenario, compensate for the cumulative errors between projected frames, and improve the point cloud accuracy of real-time 3D reconstruction.
Automatic feedthrough cancellation methods for MEMS gyroscopes
Authors: Fan Chongyang , Wu Yuting , Gu Liutao , Wang Zijie , Liu Wu , Cui Feng
Published: December 2023

The feedthrough effect can significantly affect the performance of MEMS gyroscopes and even lead to device failure. In order to address the inevitable problem of feedthrough capacitance caused by microfabrication process and circuit structure, two automatic feedthrough cancellation solutions are proposed based on the analysis of the feedthrough effect. Firstly, an equivalent feedthrough model is established for MEMS gyroscopes. Then, through theoretical derivation and model simulation, various influences of feedthrough effect are analysed, and the critical value of feedthrough capacitance is calculated to achieve better compensation effects. For feedthrough capacitance greater than the critical value, a feedthrough cancellation method utilizing AD5231 digital potentiometer for generating an inverse signal is designed. For the situation of feedthrough capacitance less than the critical value, a feedthrough cancellation method based on pure digital circuit calculation is proposed. The experimental results show that the method of utilizing digital potentiometer effectively reduces the feedthrough level from −17.46 dB to −32.75 dB, and the method of utilizing pure digital circuit calculation compensates the feedthrough signal of 100.04 mV to almost zero (2.44 mV) within the range of ADC sampling accuracy. These two methods can accurately and quickly suppress feedthrough signal to improve the detection performance of MEMS gyroscopes, and are expected to meet the needs of future mass production. In addition, they can be widely applied to various MEMS devices that require feedthrough cancellation.
A novel conservative dynamics envelope of vehicle lateral stability under different tire characteristics
Authors: Li Jialin , Lu Jianwei , Lu Hangyu , Wei Heng , Wu Bofu , Jiang Ping
Published: December 2023

This paper proposes a dynamic stability envelope based on safety maneuver margin to estimate the lateral stability of nonlinear vehicle systems with different tire characteristics (i.e. understeering (UN) and oversteering (OV) vehicles). Firstly, this study employs phase portraits and handling diagrams to investigate the number of equilibrium points and the evolution trend of state variables under various manipulation conditions. Subsequently, the nonlinear bifurcation theory is applied to analyze the characteristics of the vehicle equilibrium, aiming to derive the safe maneuver margin of the vehicle and restrict the vehicle instability. Within this proposed margin, the stability of each point of the nonlinear system is analyzed using the local linearization method. Simultaneously, a more conservative estimate of the vehicle handling stability is further obtained by applying stability criteria, resulting in the dynamic stability envelope, which ensures vehicle stability. Finally, the reliability of the dynamic stability envelope results based on the safety maneuver margin is validated under sine-with-dwell conditions (SDC) and steady-state cornering driving scenarios (SSC). The simulation results indicate that maintaining an appropriate understeering range keeps the vehicle stable.
Seeking and sharing information about the threat of nuclear war
Authors: Savolainen Reijo
Published: December 2023

The present study contributes to information behavior research by examining how people seek and share information related to the threat of nuclear war. To achieve this, a sample of 1279 posts submitted to Quora—a social Q&A site—were scrutinized by means of qualitative content analysis. The analysis was based on identification of three question types indicative of attempts to seek information and five answer types expressive of information sharing. The findings indicate that the online participants mainly presented opinion questions, while the role of fact questions remained marginal. While sharing threat-related information, the participants primarily offered opinion answers. To a lesser extent, the repertoire of answers also included explanation, prediction, fact, action directive and encouragement answers. The predominance of opinion answers is understandable because there is no recent experience about the use of nuclear weapons against civil targets. Therefore, much of threat-related information shared in online discussion necessarily originates from people’s personal views of what a nuclear war and its effects could be like. The findings highlight that people mainly seek opinions of other people, rather than factual information about the threat of nuclear war.

Published: December 2023

Background:

Acupuncture is a potentially effective non-pharmacological treatment for insomnia.

Objective:

We observed the responses of patients with insomnia to acupuncture in routine clinical practice. In addition, we explored patient characteristics that might affect the treatment response to acupuncture for insomnia.

Methods:

Medical records of patients with insomnia in a Korean medicine clinic with baseline Insomnia Severity Index (ISI) scores ⩾8 and Pittsburgh Sleep Quality Index (PSQI) scores ⩾5 were reviewed. Acupuncture was applied at ST43, GB41, ST41, SI5, HT3, KI10, HT7 and ST3, for 1–2 months. The ISI and PSQI were measured monthly to assess insomnia severity. The effect of acupuncture over time was analyzed using a multilevel linear model for repeated measures. In addition, logistic regression was used to explore predictors of treatment response.

Results:

A total of 91 patients with insomnia aged 59.2 ± 12.5 years (mean ± standard deviation (SD)) (90.1% female) were included in the analysis. After the acupuncture treatment, ISI scores were significantly reduced by −3.75 (95% confidence interval (CI) = −4.99, −2.50) and −4.69 (95% CI = −6.22, −3.16) after the first and second month, respectively. The PSQI global scores also improved, and sleep duration showed a tendency to increase by 0.35 h (95% CI = −0.17, 0.86) after acupuncture treatment. Three cases of mild fatigue were reported. In addition, higher baseline pain/discomfort predicted a greater likelihood of response after acupuncture treatment (odds ratio (OR) = 1.66, 95% CI = 1.10, 2.60).

Conclusion:

In a real-world setting, the insomnia of outpatients in a clinic was slightly alleviated after acupuncture treatment. These findings require validation by randomized controlled trials.
Accounting Knowledge: A Tool for the Success of Females in Small-scale Enterprises in the Post-COVID-19 Era
Authors: Adeosun Oluwaseun Titi
Published: December 2023

Despite the fact that the pandemic has made entrepreneurs out of people, especially females who venture into diverse small-scale enterprises to cope with the residue of the pandemic, the majority of the enterprises seem to be dwindling and stagnant. The knowledge of accounting will provide a platform for the effective administration and management of these enterprises. This study specifically probes the methods used in the management of finances, inquires about the continuity plan and explores the contribution of entity theory to the success of females in small-scale enterprises in the post-COVID-19 era. The study adopts an exploratory research design. A mixed-method sampling technique was adopted (multi-stage and judgemental). In-depth interviews were used to collect data from 36 participants who commence their business during and after the ease of the lockdown in southwestern, Nigeria. Findings revealed that females in small-scale enterprises lack accounting knowledge. This, coupled with the motivation of the establishment of their businesses has predominantly affected its administration and management which has led to their lack of strategic plan for the continuity of their businesses. Despite their lack of knowledge of entity theory, some of them have been applying it in the administration of their businesses. It is therefore recommended that irrespective of the motivation behind the establishment of their businesses, a proper book-keeping record should be maintained. This will enable them to track their profit and growth over time, enlighten them to be conservative with their finances and assist them to develop a strategic plan for their business continuity.
The Development and Psychometric Testing of the Scale of Cultural Sensitivity of Health Care Professionals in Japan
Authors: Tanaka Hiroko , Arakida Mikako
Published: December 2023

Introduction:

The development of cultural sensitivity is essential for health care professionals but there are few tools to measure this quality in Japan. The purpose of this study was to develop a scale of cultural sensitivity for Japanese health care professionals and examine its reliability and validity.

Method:

A draft scale was created through conceptual analysis and a questionnaire was completed by 515 health care professionals and 1,322 college students. Exploratory and confirmatory factor analyses were used to determine suitable scale items and examine model fitness.

Results:

The four-factor 18-item scale showed acceptable model fitness. Cronbach’s α coefficient exceeded .90 and correlation coefficients for criterion-related validity were over .29. Construct validity was confirmed by the significantly higher score of the cross-culturally experienced groups. The intraclass correlation coefficient was .642 (professionals) and .722 (students).

Discussion:

This reliable and valid scale for Japanese health professionals and college students may be used to evaluate training programs to increase their cultural sensitivity.

Published: December 2023

Despite increasing father involvement in rearing their children, research on the determinants of parenting stress has focused on mothers, ignoring the mutual influence between the two parents—fathers and mothers. Using the actor–partner interdependence model, we examined fathers’ and mothers’ reciprocal influences on parenting stress, with a focus on interparental relationship and co-parenting. Data from 174 couple dyads from the Dads Matter-HV© program were analyzed. Findings showed that both mothers’ and fathers’ co-parenting directly reduced their own parenting stress. Fathers’ co-parenting significantly mediated the association between their own interparental relationship and parenting stress and the association between their own interparental relationship and mothers’ parenting stress. Findings suggest fathers’ perceptions of co-parenting are an important protective factor to be targeted by early child and family programs among parents at risk for chronic and parenting stress.
Health monitoring of steel structures using surface mountable and detachable PZT sensor
Authors: Singh Sachin Kumar , Shanker Rama , Ranjan Achint
Published: December 2023

A lot of collapse in the infrastructure were reported in the last decades, hence the need for monitoring the health of the structures also arises. There are various techniques available to monitor the health of the structure, in which Electromechanical impedance (EMI) technique is one of them. In EMI technique, the PZT sensor is bonded to/embedded in the structure using epoxy. The thickness of epoxy layer used as an adhesive should be maintained as thin as possible, which cannot be achieved ideally, which introduces shear lag effect such that is, complete strain transfer cannot take place between PZT and host structure. The shear lag effect caused is one of the major drawbacks in the EMI technique and due to this effect, the damage detection sensitivity decreases. To overcome this drawback, in this study a new sensor named Surface Mounted PZT Sensor (SMPS) is proposed for the steel structure. Along with this, the performance of other sensor configurations such as conventionally bonded PZT with epoxy that is Surface Bonded PZT Sensor (SBPS) and Adhesive Covered Surface Bonded PZT Sensor (ACSBPS) are also been compared. The results show that, SMPS was working effectively and was more sensitive compared to SBPS and ACSBPS.

Authors: Pu Huayan , Fu Shibo , Wang Min , Fang Xuan , Cai Yi , Ding Jiheng , Sun Yi , Peng Yan , Xie Shaorong , Luo Jun
Published: December 2023

With the increasing requirements for vibration isolation in multiple degrees of freedom (multi-DOFs), active control strategy is becoming more meaningful. However, the vibration isolation performance is limited by the time delay of feedback control, and cannot meet higher requirements. Therefore, this paper proposes a multi-DOFs active vibration hybrid control (AVHC) strategy based on a piezoelectric platform. The AVHC integrates the adaptive feedforward control based on the modified recursive least squares (MRLS) algorithm, and the feedback control based on the integral force feedback (IFF) algorithm. To achieve advanced response, the ground-based vibration signal is offset by the MRLS algorithm. To further reduce the coupling of multi-DOFs, the feedback and feedforward coordinates are fused through the matrix transformation, and the signals are linearly superimposed by the AVHC. The experimental results show that the AVHC can further reduce the resonance peaks of the three translational directions ( X/ Y/ Z) compared with the feedback (FB) control. The resonance peaks are reduced from 14.6 dB (FB) to 3.11 dB (AVHC), from 14.56 dB (FB) to 5.14 dB (AVHC), and from 12.44 dB (FB) to 3.78 dB (AVHC) in X/ Y/ Z directions, respectively. The attenuation rates are improved by 73.36%, 66.19%, and 63.10% in X/ Y/ Z directions, respectively.

Authors: Musiałek Ireneusz , Kesy Andrzej , Olszak Artur , Choi Seung-Bok
Published: December 2023

This article concerns the identification of a transfer function which contains principal design and dynamic parameters of a hydraulic viscous disc clutch operated and controlled by an electrorheological (ER) fluid as a working fluid. A mathematical model of clutch dynamics is created as part of the clutch identification. It is considered that the changes in torque over time are described by transfer function represented by the first-order system with time delay. A prototypic clutch and a test bench are constructed, and tests are performed. A high voltage step input is used to trigger the torque changes. Constant parameters of the first-order system with time delay are identified on the basis of bench tests. According to the values of these parameters, a proportional-integral (PI) controller is selected for the closed-loop control system. It is found that operation of such a control system utilizing the identified design parameters is acceptable with high accuracy under external disturbances.

Authors: Alassaf Muath S. , Hasubah Saad M. , Sharbib Shadan H. , Alhammad Reem , Othman Ahmad A. , Alsulaimani Mahmoud A. , Qazali Ahmad A.
Published: December 2023

Objective

The aim of this study is to evaluate the quality and readability of the Arabic web-based information about cleft lip and/or palate (CL/P). Materials and Method: Searching in three engines and checking eligibility for the first 300 websites. The quality of the included websites (72) was assessed using the DISCERN questionnaire, JAMA benchmarks, and HON code. The readability of the websites was assessed using three readability tests: FKGL, SMOG, and FRE. Then, data analysis was done.

Results

All checked websites were partly related to CL/P and contained medical facts. The affiliation of most of the websites was commercial 33 (45.8%). The mean overall DISCERN score was 2.87 (± 1.61). The maximum score was not achieved by any website, and only one (1.4%) website had the minimum score. For JAMA benchmarks, the currency was the most achieved item in 39 (54.2%) websites, and none of the websites achieved the four items. Only one website had the HON code. Based on the FRE scale, the level was very easy for most of the websites 57 (79.2%).

Conclusion

The available content about CL/P is readable but with moderate to poor quality and trustfulness. Undoubtedly, there is a serious need to increase and improve the quality of the web-based Arabic population's knowledge about CL/P, especially by governmental institutions and universities. Establishing specialized websites for CL/P is also needed.
“We Are All Teachers Here”: Identity Construction in a 4-Year Lab Choir
Authors: Adams Kari
Published: December 2023

The purpose of this intrinsic case study was to examine how preservice music teachers’ participation in a 4-year lab choir setting contributed to their teacher identity construction. This lab choir represents an uncommon case of peer teaching because preservice teachers enroll in the course each semester of their undergraduate career and participate as singers for multiple semesters before taking on the teacher role, at which point they are teaching an ensemble made up largely of younger students. The eight participants in this study were choral music education majors who had been members of the lab choir since their first semester at the university. Three themes emerged from the data: culture of identity construction, evolution through coursework, and peers as future selves. Participants felt the lab choir experience contributed positively to their identity construction and skill acquisition. Implications for music teacher education are discussed.

Published: December 2023

The built environment communicates value and belief structures to users. Research on gendered messaging in designed classroom spaces has shown its impact on students; thus, we sought to determine how classroom designs can have different gendered perceptions between those who use the space and those working in the design industry. In two studies, we collected survey data from undergraduates ( n = 97), and then employees at design firms ( n = 88) reacting to masculine versus feminine design patterns in classroom renders. The two groups exhibited strong, opposite correlations between their perceptions of femininity and sense of belonging, plus differences within the femininity scale itself. These findings show the importance of closer examinations of masculinity and femininity as gender constructs, and the need to further study how perceptions of designers differ from the perceptions of users.

The prevalence of atrial fibrillation (AF) in acute coronary syndrome (ACS) patients is increasing. Data on outcomes of anticoagulation in ACS patients with AF are lacking.

The aim of our study was to investigate the prevalence of stroke, myocardial infarction, bleeding complications, and all-cause mortality in this population.

PL-ACS and AMI-PL registries gather an all-comer population of ACS patients in Poland, exceeding half a million records. We have selected ACS survivors with concomitant AF on admission, divided them into subgroups with regard to the administered anticoagulation, and followed up with them for a 12-month period ( n = 13,973). Subsequently, groups were propensity score matched for age, sex, ejection fraction, diabetes, heart failure, renal impairment, and type of ACS.

The study population was divided with regard to the administration of anticoagulation. Anticoagulation was prescribed in 2,466 patients (17.6%). The (D)OAC+ patients were younger; however, comorbidities were more prevalent in this group. The 12-month follow-up showed that the (D)OAC+ patients had significantly lower rates of all-cause mortality, myocardial infarction, and ischemic stroke, with no significant increase in bleeding events. After matching, the study groups consisted of 2,194 patients each and showed no differences in baseline characteristics. The outcomes of the 12-month observation were similar to the findings before matching.

This all-comer national registry analysis shows that the use of guideline-recommended therapy and anticoagulation in ACS survivors with AF is associated with a lower rate of all-cause mortality, recurrent myocardial infarction, and ischemic stroke.

This article reflects the perspectives of journalism educators responsible for preparing journalists for careers in the Middle East and North Africa region, which has received little attention in trauma education research. A survey with quantitative and qualitative questions is used to reflect opinions of 101 journalism educators from Algeria, Sudan, and Palestine on journalism trauma-focused education and to elicit their attitudes toward incorporating trauma education into their institutions’ journalism curricula. The findings revealed that journalism educators are particularly cognizant of the role of trauma in journalism practice and the relevance of incorporating trauma education elements into journalism curricula. Journalism educators have identified a number of barriers to incorporating trauma into their institutions’ journalism curricula, as well as various perspectives on how to incorporate trauma-focused education into journalism curricula, which could call for changing how journalism is taught in their respective institutions. The study establishes a methodological foundation for other scholars to use when investigating triangulation (or the lack thereof) among educators, students, and practitioners in their own communities.

Due to demographic changes and structural developments in the healthcare system, an increasing number of patients receive home care nursing in Denmark. Little is known about the complexity of home care. The aim of this paper was to investigate the challenges that home care nurses experience in their clinical practice by studying factors related to home care nurses’ experiences of encounters with patients as burdensome. A population-based survey was undertaken involving all nurses in homecare services in one municipality in Denmark. The participating nurses registered all home care contacts by the patients during the daytime for 1 week. A registration form was used including a series of items designed to identify factors related to the perceived burden of each visit. Statistical frequency analyses were used to examine factors related to the home care nurses’ experiences of encounters with patients as burdensome, and to investigate the challenges that home care nurses meet in their clinical practice. Home care nurses estimated 7.6% of 941 representative homecare visits as burdensome. Assessment of burden was associated with patients being below 60 years of age, time consumption and unexpected problems during the visit, especially of a psychosocial nature. Even though <10% of the encounters were considered burdensome, there is reason to believe that an increase can be expected due to ongoing emphasis on achieving greater efficiency in the healthcare system.
Maintenance Effects for Preschool Students Participating in First Step Next

In preschool settings, ample evidence has long existed that some administrators and educators rely heavily on exclusionary practices to address unwanted behaviors despite evidence they are ineffective. There is a need for evidence-based interventions that provide teachers with skills to foster positive student–teacher relationships, teach students skills that result in positive interactions with teachers and peers, and provide opportunities to practice new skills during daily classroom interactions. First Step Next (FSN) is a short-term, multi-component Tier 2 intervention that helps address these needs. The current study examines the extent to which the immediate post-intervention effects were maintained after the FSN intervention was delivered in U.S. preschool classrooms. Results provide evidence that initial, post-intervention gains reported for social skills, problem behavior, student–teacher conflict, and relational aggression domains were maintained for 2 months post-intervention. The current study adds to the evidence base suggesting that FSN is a promising alternative to exclusionary discipline as its’ implementation addresses several factors contributing to continued reliance on these ineffective approaches such as (a) the escalation of conflicts with students with challenging behavior, (b) failure to anticipate and defuse problem situations, (c) unclear communication of behavioral expectations, and (d) unskilled use of teacher directives.
What role should we play to be effective evaluators? – practitioner reflections
Authors: Donaldson-Murdoch Callum , Adler Rebecca , Jasinghe Dui
Published: December 2023

There is still widespread debate about the role that an evaluator could, should or even must play. Evaluations are often complex and require a broad array of interlinked roles and areas of expertise, making it difficult to generate a singular definition of an evaluator. Furthermore, an evaluator may be expected to change their responsibilities and actions throughout the stages of an evaluation, changing the role they play. As practitioners, we believe there is value in contributing to this discussion, providing our perspectives based on personal experience and data collected during the 2022 European Evaluation Society conference. In this article we seek to describe six evaluator traits which we believe to be the most influential to the roles which we play, and six evaluator roles which best illustrate the impact of changing these traits.
A qualitative feasibility and acceptability study of an acceptance and commitment-based bibliotherapy intervention for people with cancer

Self-directed bibliotherapy interventions can be effective means of psychological support for individuals with cancer, yet mixed findings as to the efficacy of these interventions indicate the need for further research. We investigated the experience of individuals with cancer after using a new self-help book, based on Acceptance and Commitment Therapy (ACT). Ten participants with cancer (nine females and one male, 40–89 years old) were given access to a bibliotherapy self-help ACT-based book and participated in post-intervention semi-structured interviews. Five themes were generated from reflexive thematic analysis: (1) The value of bibliotherapy (2) Timing is important (3) Resonating with cancer experiences (4) Tools of the book (5) ACT in action. The book was found to be acceptable (self-directed, accessible, understandable content, good responsiveness to exercises) and feasible (easy to use, ACT-consistent). Although not explicitly evaluated, participants’ reports indicated defusion, present moment awareness, and consideration of values, as the ACT processes that contributed to adjustment, via helping them to regain control over their lives and become more present within the moment. Findings also indicate that the intervention may be best accessed following completion of initial medical treatment.
Use of motivational regulation strategies and its relations to motivational beliefs in a college English course context
Authors: Luo Sha , Gan Zhengdong
Published: December 2023

While motivational regulation strategies (MRSs) both as a core facet of self-regulated learning and as a pedagogical issue have attracted increasing attention from researchers and practitioners, what motivational regulation strategies learners of English as a foreign language (EFL) or English as a second language (ESL) tend to use and how these strategies may be associated with learner motivational beliefs in English learning remain under-researched. To fill this research gap, this study aims to contribute to a holistic understanding of Chinese EFL students’ use of MRSs and its relations to English learning motivational beliefs. Data were collected from 638 non-English major undergraduate students through two self-report questionnaires in a College English Course context. Results showed that students reported high frequency use of performance-enhancement or interest-related strategies while reporting using other types of regulation strategies (e.g. performance-avoidance self-talk) to a lesser extent. Structural equation modeling (SEM) analyses suggested that among the four types of motivational beliefs investigated in this study, control of learning beliefs, intrinsic goal orientation, and extrinsic goal orientation were the top three most powerful predictors of the students’ use of MRSs in English learning. Pedagogical implications and directions for future research were also discussed.
