Vibration Characteristics and Control Algorithms for Semi-Active Suspension of Space Exploration Vehicles
Authors: Shenvi Mohit , Gorantiwar Anish , Sandu Corina , Taheri Saied
Published: May 2023

Suspension systems are an integral part of land vehicles and contribute significantly to the vehicle performance in terms of its ride comfort and road holding characteristics. In the case of Space Exploration Vehicles (SEVs), the requirement of these unmanned vehicles is to rove, collect pictures and transmit data back to the earth. This is generally performed with the help of exteroceptive, and proprioceptive sensors mounted on the main chassis of the SEV. The design of various components of such vehicles is dictated by the assumption of extreme terrain and environmental conditions that it might face. The Mars Exploration Rovers (MERs) have incorporated the use of the “Rocker-Bogie” mechanism for the suspension system which provides relative stability to the MER for various maneuvers. In this work, the “Rocker-Bogie” mechanism is modeled and simulated as a planar kinematic model using parameters of the Perseverance rover. It is found that the Rocker-Bogie tends to nullify the effects of uneven terrain by maintaining the chassis at a relatively fixed location with respect to the ground reference frame. Further, an attempt is made to replace the mechanism with a passive and semi-active suspension module at four corner wheels to study the effects that the semi-active suspension would have on the chassis dynamics of the MER. Lastly, a comparative analysis of the vertical acceleration of the chassis using different suspensions was performed. This concluded that the rocker-bogie mechanism does help to stabilize the chassis dynamic behavior to a greater extent. Future work could include an attempt to utilize the rocker-bogie chassis dynamics as the ideal condition to develop control strategies that can improve the chassis dynamics if individual semi-active suspension systems were employed.
Improving HALT Testing and Quantification with FDS Analysis
Authors: Stoll Cherie , Vande Kamp Jade , Quellet Ryan
Published: May 2023

Highly accelerated life testing (HALT) identifies potential failure modes and operating limits in a brief timeframe. Generally, engineers control the vibration portion of a HALT test using overall acceleration (gRMS) as the sole metric. gRMS is a broad-spectrum intensity measurement that allows engineers to make decisions with a simplified version of their product’s response. A more comprehensive and accurate metric that considers relative fatigue is needed to improve confidence when setting HALT test durations and determining when to remove a test item from the table or stop the test. This paper presents an approach that improves the quantification of the vibration portion of a HALT test using fatigue damage spectrum (FDS) analysis. The FDS allows engineers to analyze the vibratory environment from a HALT machine and compare it to a desired accrued fatigue level. Applications of the new approach include 1) analyzing variations in relative fatigue due to a change in mass, position on the HALT table, or orientation, and 2) comparing the accrued fatigue for multiple samples while monitoring critical components and known or suspected failure locations. This paper provides example applications that support the proposed method over the standard gRMS metric.
The Effect of the Awareness of the Importance of Liberal Education on the Wage and Job Satisfaction in the Labor Market
Authors: Choi Kang Shik , Park Cheolsung
Published: May 2023

This paper conducted an empirical analysis of the effect of awareness of the importance of liberal arts education on individual wages, job satisfaction, and non-cognitive ability using data from the 11th and 18th supplementary surveys of the 「Korea Labor and Employment Panel Survey」. The main findings were as follows: First, individuals who recognized that liberal arts education in college was important received approximately 9% to 13% higher hourly wages in the labor market after graduation than individuals who did not. Second, individuals who recognized that liberal arts education was helpful in their work life had higher overall job satisfaction than individuals who did not, and highly valued the work they were doing. Third, individuals with a positive perception of liberal arts education showed a locus of control score (one of the measures of non-cognitive ability) of about 0.15 standard deviation points higher than those who did not. This accounts for about one-tenth of the wage gaps generated by the differences in the degrees of perception regarding liberal arts education This result is presumed to be because liberal arts education cultivates both cognitive and non-cognitive abilities, and at the same time, liberal arts education is more effective in an uncertain environment than in a stable one.

Authors: Nour Hussameldin M , Magsi Abdul Malik , Abdalla Hashim E Elmansi , Mcwhirter Alexandra , Gadoura Ahmed , Sajid Muhammad S
Published: May 2023

Background: Pain is a very important factor in patient recovery and satisfaction. Following incision and drainage of perianal abscess, wound packing has been found to be very painful. The aim of this study is to compare packing the wound and not packing the wound after incision and drainage (I&D) of perianal abscess, taking into account recurrence rate, rate of occurrence of perianal fistula as well as post-operative pain.

Materials and Method: Standard medical electronic databases were searched with the help of a local librarian and relevant published randomised controlled trials (RCT) were shortlisted according to the inclusion criteria. The summated outcome of post-operative pain score, recurrence rate, and rate of occurrence of perianal fistula was evaluated using the principles of meta-analysis on RevMan 5 statistical software.

Result: Three RCTs on 490 patients undergoing I&D of perianal abscess were found suitable for this meta-analysis. In the random effects model analysis, the post operative pain score was statistically lower in NPG [risk ratio 0.66, 95%, CI (0.36, 0.97), Z=4.25, P=0.0001]. There was no heterogeneity [Tau2=0.15; chi2=9.32; df=6; I2=36 %; p=0.16] between the studies, however, statistically it was not significant. In addition, there was no statistical difference between the 2 groups in terms of recurrence of perianal abscess or the occurrence of perianal fistula [risk ratio 0.64, 95%, CI (0.31, 1.31), Z=1.23, P=0.22], [risk ratio 1.41, 95%, CI (0.89, 2.23), Z=1.47, P=0.14] respectively.

Conclusion: Not packing the wound post I&D of perianal abscess is associated with significantly reduced VAS pain scores, which may result in improved recovery and patient satisfaction and has no effect on recurrence rate or the occurrence of perianal fistula. However, more RCTs recruiting a greater number of patients are required to endorse these findings.
Warts, hypogammaglobulinemia, infections, and myelokathexis (WHIM) syndrome and tetralogy of fallot; Case report and literature review
Authors: Khojah Amer , Alshareef Hadeel , Alzahrani Lujain , Binhussein Mohammad , Bukhari Ameera , Khojah Imad
Published: May 2023

WHIM (Warts, Hypogammaglobulinemia, Infections, and Myelokathexis) syndrome is a rare primary immunodeficiency disorder characterized by susceptibility to human papillomavirus (HPV) infections, neutropenia, and hypogammaglobulinemia. WHIM syndrome is caused by a gain-of-function mutation CXCR4, leading to increased responsiveness of neutrophils and lymphocytes to CXCL12. This results in an accumulation of atypical hypersegmented mature neutrophils in the bone marrow and peripheral blood neutropenia. This case report discusses a 10-year-old girl who was diagnosed with WHIM syndrome at the age of four years following Haemophilus influenzae meningitis. She was found to have Tetralogy of Fallot at birth, which was surgically repaired when she was one year old. She was also found to have significant neutropenia during surgery and received multiple doses of G-CSF with a good response. She presented to the hospital at the age of four years with fever, neck stiffness, lethargy, and headache and was diagnosed with H. influenzae meningitis. Her immunology workup revealed significant neutropenia and hypogammaglobulinemia, as well as low antibody levels to H. influenza type B, tetanus toxoid, and Streptococcus pneumonia, despite up-to-date vaccination. Furthermore, decreased levels of T cells and B cells were detected. The patient was started on IgG replacement therapy and Bactrim prophylaxis. Bone marrow biopsy revealed granulocytic hyperplasia and occasional hypersegmented neutrophils, suggesting myelokathexis. Genetic testing revealed a heterozygous CXCR4 mutation with a premature stop codon (p.Ser338Ter), confirming the diagnosis of WHIM syndrome. This case report highlights the association of WHIM syndrome with congenital heart defects, such as Tetralogy of Fallot. A literature review revealed three other cases of congenital heart defects in patients with WHIM syndrome, indicating a potential role for CXCR4 and CXCL12 in septum formation. The rarity of the disorder and the lack of a universal screening tool makes the diagnosis of WHIM syndrome difficult. Therefore, physicians should consider WHIM syndrome in patients with congenital heart defects, particularly if they have recurrent HPV infections, neutropenia, and hypogammaglobulinemia.

Published: May 2023

The purpose of this study to contribute to the existing literature by investigating at the impact of remittances on Pakistan’s poverty, both in the long run and over the short run over the period from 1980 to 2018. Poverty is the dependent variable, and independent variables are inflation, education, trade openness, domestic growth product per capita, and remittance. For this purpose, ARDL bound testing technique is used to examine the effect of remittances on Pakistan’s poverty in multidimensional form. To confirm the results' robustness, this study used two proxies of poverty. For Model 1, consumption of household (HHC) used as poverty's proxy. For 2nd model, the rate of infant mortality (IMR) is taken as a proxy of poverty. Unit roots' outcomes indicate appropriateness to apply the ARDL bond testing to conclude on co-integration and (ARDL) regression analysis. Co-integration test results indicate that relationships of long run are present among the study variables of models 1 and 2 because both models' the value of F-statistics is greater than the serious value. In model 1 (long-run and short-run), results represent the impact of remittance (REM) is negative on poverty (HHC). From previous studies, remittance has an adverse influence on poverty. In model 2 (long-run), results represent the impact of remittance (REM) is negative on poverty (IMR). However, short-run results represent that remittance (REM) is positive on poverty (IMR). The negative relationship between remittances and poverty implies that remittance increases can decrease the poverty level in Pakistan. The results show that remittances have an important role in reducing poverty in the country.

AN INVESTIGATION OF THE FACTORS ENHANCING WOMEN EMPOWERMENT IN PAKISTANI SOCIETY
Authors: Razzaq Saadia , Mehmood Sheikh Tariq
Published: May 2023

Woman empowerment is an important issue of the 21st century. Women are an important part of any society who contribute to the development process. Since the creation of Pakistan women's empowerment has been neglected. According to the constitution of Pakistan, education is the basic right of every female living in Pakistan but the actual situation is different (Khan, 2020). In many areas women are deprived of social development processes such as education, health, decision making in family matters and access to technology. They even don’t know what their right are and they don’t get equal opportunities of living respectful human life. Many plans and policies have been developed for women development but no one could be implemented. The National Policy 2002 aimed to ensure female participation in economic growth and decision making. Moreover, a bill ‘Criminal Law Act 2004’ against the honor killing of females was also approved by the Parliament of Pakistan (Bushra & Wajiha 2013). Similarly, many laws have been formulated regarding women's empowerment but the issue of women's development is still there and needs to be focused on the well-being of women and ultimately the development and prosperity of society. The determinants of low woman empowerment are socio-cultural issues, economic issues, poverty, lack of awareness, and gender discrimination. The scope of this study is to investigate factors that increase women's empowerment.

Authors: Shahid Rimshah , Ahmed Bilal
Published: May 2023

The United Nations Agenda 2030 for achieving Sustainable Development Goals (SDGs) requires a concrete approach for effective implementation of SDGs as these global goals provide a blueprint to achieve a prosperous, better, and more sustainable future. However, SDG-11 – sustainable cities and communities – holds an imperative place among all the seventeen goals as it targets social, economic, and ecological sustainability and development, and this can be achieved through building community resilience. Resilience is the capacity to prevent, mitigate, absorb, and adapt in pre and post-disaster or crises, and a resilient community – having all the said capacities and capabilities – can sustain any kind of uncertainty. The objective of this paper is to highlight the significance of resilience in making cities and communities sustainable and to identify the possible outcomes of embedding the four indicators of resilience – healthy and active community resources, elevated priority to lifeline functions, resilience measurement and risk management, and partnership and executive management – in the development framework and policy structure of Pakistan. The findings and results have been supported through past pieces of literature such as research papers, annual reports, project documents, journal articles, websites, policy frameworks, and other documents on SDGs, resilience building, community resilience, and the importance of resilience in achieving SDG-11. The findings reveal that integrating the four indicators of resilience can increase risk knowledge at the local level to make the public well-prepared, enhance connectedness and cohesion to make healthy community networks, ensure availability and fair distribution of community resources and lifeline functions, and create an appropriate governing structure for effective and expeditious execution of policies and strategies.

Authors: Bernard Hanish Dr. Shak
Published: May 2023

The Social Movements and Political Violence: An International Case paper will define political violence in a general and theoretical sense. It will classify major types of political violence and concentrate on major four types of political violence. Then, it will apply a particular one to an international case of social movement, specifically in Iraq where a popular uprising took place in October 2019 and is currently affecting politics in Iraq. Iraq has witnessed a new wave of protests, but it was unprecedented and almost unique and has distinctive characteristics. These protests included the masses of protesters who felt the flaws of the system and the corruption of the authority, and they realized that the political elite as a whole is unable and/or unwilling to implement their demands. Protesters practiced a variety of methods in expressing their demands, ranging between peaceful demonstrations, civil disobedience, and armed clash. They were accompanied by bloody violent incidents that killed over 800 people and injured tens of thousands. The paper will examine the reasons for the protest, and how and why the government and some armed pro-government groups used violence and assassinations against activists. What was the reaction to the violence? What was the result of the uprising? Did it reach its goals? and what are the prospects of repeated demonstrations and the possibility of regime change? The paper will analyze that and present a future outlook of such a social movement.

ASSESSING THE IMPACT OF OVERFISHING ON AFRICA AND SUSTAINABLE FISHING PRACTICES
Authors: Xitong Zhang Chloe Zhang
Published: May 2023

n this study, we investigated the problem of overfishing along the African coastlines, using two entities of South Africa and Central Africa Republic for data analysis, concentrating on the causes of overfishing and potential preventative measures. In order to understand the current overfishing problem in Africa, we first looked at the high local and global demand for seafood, the financial incentives for overfishing, and the ineffective government regulations and enforcement of sustainable fishing techniques. Through our analysis, we were able to pinpoint several important elements that contribute to overfishing in Africa, such as ineffective fisheries management regulations, lax law enforcement, a lack of alternatives for fishing communities to earn a living, and a lack of knowledge of sustainable fishing methods. We suggested several potential solutions to address these problems, such as implementing and enforcing sustainable fishing laws, encouraging alternative livelihoods for fishing communities, enhancing fisheries management through community-based methods, and raising awareness of sustainable fishing methods. Also, we offered pertinent academic references to back up our suggestions.
Extended Scope Physiotherapists are Effective and Safe in the Emergency Department: A Systematic Review and Meta-Analysis
Authors: Souter Brittany , Jones Anne , Sheppard Lorraine , Crowe Michael
Published: May 2023

Purpose: Extended scope physiotherapists (ESPs) are an innovative approach to service delivery that have emerged in response to increasing pressures on emergency departments (EDs). While previous systematic reviews have suggested that ESPs have a positive impact on ED outcomes, clinical practice recommendations based on limited evidence highlight a pressing need for evaluation studies to truly determine their effectiveness and safety in this setting. Therefore, the objective of this systematic review and meta-analysis was to evaluate the clinical effectiveness and safety of ESPs when delivering services in EDs. Method: Systematic literature searches were conducted using the online databases: Medline (Ovid), CINAHL (EBSCOhost), Scopus, PEDro, Cochrane Library and Informit in October, 2019. Randomised controlled trials (RCTs) or cohort studies investigating the clinical effectiveness and safety of ESPs in EDs in comparison with usual ED medical care providers were eligible for inclusion. Data extraction was completed using a form specifically developed for the study. The quality of each study was assessed using the Crowe Critical Appraisal Tool (CCAT) as well as a subjective assessment of bias, and the level of evidence was graded using the National Health and Medical Research Council (NHMRC) evidence hierarchy. Random-effects model meta-analyses were conducted using Stata (version 16.1). Results: Eleven studies met the inclusion criteria for the systematic review. These studies provided III-1 to III-3 evidence, with quality scores ranging from 50% to 93%. Consistent positive results were found regarding ESP clinical effectiveness and safety with meta-analyses demonstrating significant reductions in wait time (Cohen’s d effect size: -0.54; 95% confidence interval [CI]: -0.64 to -0.45) and length of stay (Cohen’s d effect size: -0.79; 95% CI: -0.86 to -0.72) for patients managed by ESPs. Although, confounding of results by treatment urgency made it difficult to establish a clear causal link between ESP services and outcomes. Conclusion: Although it was not able to be suggested that ESPs are an appropriate substitute for usual ED medical care due to the presence of bias and confounding, the results highlighted that ESPs, as an additional staff member in EDs, improve throughput and access to care for patients in lower urgency triage categories.
Investigating Doctor of Physical Therapy Student Stress During Pandemic Related Curricular Changes
Authors: Halle KeithAnn , Hastings Jennifer
Published: May 2023

Introduction: Stress level in physical therapy students has been a focus of research due to multiple documented effects related to physical health, mental health, and ability to learn. Self-reflection has also been a focus of education research, relating it to personal learning, critical thinking, and demonstrable development of professional behaviors and skills. The aim of this study is to investigate student stress in response to programmatic changes wrought by the pandemic and whether stress impacted student self-reflection. Review of literature: Self-reflection is positively associated with growth of professional behavior and academic performance. Student level of self-reflection has been shown to be negatively impacted by stress. Subjects: A convenience sample of 35 students entering the program fall 2019 made up the participants. Methods: Outcome measures were collected six times over two academic years. The Self-Reflection Insight Scale (SRIS) consists of 20 statements rated on a 5-point Likert scale with 3 subscales: need for reflection (N), engaging in reflection (E), and insight (I), scoring from 10 to 100. The Perceived Stress Scale (PSS-10) is a 10-item questionnaire rated on a 4-point Likert scale, scoring from 0 to 40. Results: SRIS scores increased significantly from time 1 to 2, prior to the campus closure; no significant change for times 3 through 6. PSS scores indicated a higher percentage of students reporting a high level of stress at time 3 in the months after campus closure, decreasing significantly from time 3 to 4 during virtual/hybrid learning and increasing from time 5 to 6 as students prepared for clinical internship. No correlation was seen between SRIS and PSS, however a negative correlation was observed between SRIS subscale I and PSS at time 4 and 5. Discussion: Student perceived stress decreased during the study despite a universally stressful time. Student stress increased as students prepared for their first clinical internship experience, consistent with prior research. Initial gains in student self-reflection did not significantly change during the 1.5 years of the pandemic indicating that despite multiple academic and social challenges, students were able to maintain, but not grow, their level of professional self-reflection. Research is needed to further describe the relationship between stress and insight. Conclusion: The Program’s response to pandemic mandates may have positively influenced student stress.

Purpose: Paramedics are routinely called to patients presenting with mental health concerns. Previous literature suggests paramedics find this patient group challenging. However, no study has investigated whether paramedics find mental health presentations (MHP) more challenging relative to other patient presentations, or whether certain paramedic variables relate to their perceived ability to manage MHP. This study investigates differences in paramedics’ perceived ability to attend to MHP compared to other patient presentations, and whether their perceived ability is related to their level of experience or location of work (metropolitan or rural). The study also explores paramedic’s experiences and perspectives of MHP. Method: Operational paramedics in Australia (n = 138) completed a survey assessing their perceived ability to respond to mental health, cardiac, respiratory, and trauma-related presentations. A repeated measures ANOVA tested differences in perceived ability between these patient presentations. T-tests and Pearson’s correlations were conducted to determine whether years of experience or location of work related to their perceived ability for MHP. Nine paramedics were also interviewed, and a thematic analysis conducted to gain insight into paramedic’s experiences and perspectives of MHP. Results: Paramedics reported a significantly lower perceived ability to respond to MHP relative to each other patient presentation measured. No relationships were found between a paramedic’s perceived ability to respond to MHP and their length of work experience or location of work. Interviews with paramedics revealed four superordinate themes: 1) inconsistent conceptualization of their role, 2) feelings of helplessness and frustration, 3) stigmatized views of patients with a mental illness, and 4) inconsistent views of knowledge and learning relating to MHP. Conclusions: Paramedics believe they have a significantly poorer ability to respond to MHP relative to other patient presentations. Education and training focused on defining a paramedic’s role for MHP as well as reducing stigmatized views of patients with a mental illness may improve paramedic’s care of this cohort of patients.

Published: May 2023

There is a shortage of Black men pursuing and or entering the pre-K-12 teaching profession. Some of the causes for the lack of Black men in the teaching profession stems from burnout, the school-to-prison pipeline, bad experiences as students, and a myriad of other reasons. We believe that Black men having a criminal record has not been fully explored or brought to the forefront as a major issue amongst the teaching profession and teacher preparation programs. To highlight this issue, we highlight and center the experience of one Black male who wanted to become an elementary reading teacher but was unable to due to his criminal record via a case study approach and a layered textual analysis. Specifically, we investigate what inspired a Black man’s interest in pursuing a teaching career and what factors altered or contributed to his deviation from pursuing the teaching profession. We then offer suggestions for research, practice, and policy with hopes that these suggestions provide teacher preparation programs and the teaching profession at-large with tangible tangles goals and task to address the Black male shortage in the pre-K-12 profession.

In qualitative research, there is a growing interest in understanding the use of timelines in combination with other qualitative methods. In this paper, we will address how the creation of timelines facilitated and informed the process of semi-structured interviews. We used an interpretive descriptive qualitative study to understand the perceptions and experiences of developing sexuality among female adolescents of Pakistani descent, and timelines were used as a part of the semi-structured interview process. Timelines were created in a participatory way in which girls were asked to recount significant events related to their sexuality. We found that the methodological combinations within qualitative research such as semi-structured interviews and timelines have the potential to advance knowledge regarding the experience of immigrant female adolescents’ sexuality. Using the timeline strategy to collect data helped in building rapport with the participants, allowed the participants to become active partners and navigate the process, and helped them to think about future resolutions through reflection.

Oncology nurses are essential in palliative care for cancer patients, especially at end-of-life stages. Caring for terminally ill cancer patients is stressful, accompanied by negative and positive feelings, but oncology nurses have an unavoidable responsibility. However, little is known about oncology nurses' experience in the Kingdom of Bahrain caring for terminally ill cancer patients in their final weeks or days. This study aimed to explore the experience of oncology staff nurses in providing care for terminally ill patients in the Kingdom of Bahrain, and the research answered those questions: (a) What is the experience of oncology staff nurses in providing care for terminally ill patient? And (b) How does the experience of oncology nurses in providing care to terminally ill patients impact the quality of care provided to patients? A qualitative descriptive, interpretive exploratory research design was utilized for this study to explore the experience of oncology staff nurses with terminally ill patients, conducted in two hospital settings at Salmaniya medical complex (inpatient & outpatient) oncology department. The data were collected using a purposive sampling to include 15 oncologist nurses whose experiences were across various characteristics with different professional roles and qualifications. The data were collected through 15 semi-structured interviews guided by a semi-structured interview protocol. Data were analyzed using Braun and Clarke's 2006 thematic analysis model without pretexting. The research findings revealed three key themes that emerged from thematic analysis: (1) exhausting versus rewarding experienced feelings; (2) Factors influencing Nursing care; (3) Moral Distress. End-of-life care in the Kingdom of Bahrain reflects and has been influenced by primary total nursing care. Oncology nurses reported suffering but also benefiting from their experiences. End-of-life cancer care training is needed and urged by oncology nurses, especially those younger and less experienced. Also, future studies are mandated to explore interventions to help overcome the challenges that are impeding nurses from providing high-quality care for terminally ill patients in the kingdom of Bahrain.
