Space Booking with Multistage Online VCG Mechanism: A Simulation Study Toward Practical Application
Authors: Du Bingxin , Nishino Nariaki , Kimita Koji 
Published: November 2023

Most current reservation systems include only time slots as reservation information. Customers need only to make a reservation by choosing a proper time. The value generated by a reservation is unknown until the customers are served. Therefore, an important shortcoming of current reservation systems is that they require limited information from customers, engendering a loss of social welfare. We surmise that an innovative reservation system including space value can produce more desired outcomes by considering various factors, such as social distancing during a pandemic. Based on that supposition, we adopt the Vickrey–Clarke–Groves (VCG) mechanism to achieve social welfare maximization and strategy-proofness. To offset VCG mechanism shortcomings in practical applications, we converted the VCG mechanism to a multistage online VCG mechanism that can do timely processing of customers’ reservations and can thereby maximize social welfare. The multistage online VCG mechanism generates higher social welfare than most current reservation systems, which use a first-come, first-served mechanism. Additionally, we demonstrate that, by adjusting the VCG mechanism bid number to a practical level, the reservation process can be improved considerably with a probability of more than 99% for satisfying the strategy-proofness of the VCG mechanism.

Published: November 2023

An athermal 360∘×(30∘−100∘) and F/3.5 panoramic annular lens (PAL) system is designed. Through the optical mechanical thermal analysis results based on finite element analysis (FEA), it is expected that the system will have excellent performance under extreme temperature fluctuations. Simulation shows that the system is thermally insensitive in the temperature range from −40∘C to 60°C, consistently providing great imaging capability with the modulation transfer function (MTF) value at 133 lp/mm greater than 0.3. The proposed design and analysis workflow contains an evaluation of thermal optical performance with a higher accuracy, thus having significance in future athermal optical design. We expect the designed PAL system to have a broad application prospect in the field of outdoor applications, including automatic navigation of vehicles and all-weather surveillance systems.

Published: November 2023

Background
The COVID-19 pandemic has led to substantial interruptions in critical health services, with 90% of countries reporting interruptions in routine vaccinations, maternal health care and chronic disease management. The use of non-pharmaceutical interventions (NPIs) such as lockdowns and self-isolation had implications on the provision of essential health services (EHS). We investigated exemplary COVID-19 outbreak control strategies and explored the extent to which the adoption of these NPIs affected the provision of EHS including immunization coverage and facility-based deliveries. Finally, we document core health system strategies and practices adopted to maintain EHS during the early phase of the pandemic.

Methods
This study used an explanatory sequential study design. First, we utilized data from routine health management information systems to quantify the impact of the pandemic on the provision of EHS using interrupted time series models. Second, we explored exemplary strategies and health system initiatives that were adopted to prevent the spread of COVID-19 infections while maintaining the provision of EHS using in-depth interviews with key informants including policymakers and healthcare providers.

Results
The COVID-19 pandemic and the interventions that were implemented disrupted the provision of EHS. In the first month of the COVID-19 pandemic, Oral Polio and pentavalent vaccination coverage reduced by 15.2% [95% CI = -22.61, -7.87, p<0.001] and 12.4% [95% CI = 17.68, -7.13; p<0.001] respectively. The exemplary strategies adopted in maintaining the provision of EHS while also responding to the spread of infections include the development of new policy guidelines that were disseminated with modified service delivery models, new treatment and prevention guidelines, the use of telemedicine and medical drones to provide EHS and facilitate rapid testing of suspected cases.

Conclusion
The implementation of different NPIs during the peak phase of the pandemic disrupted the provision of EHS. However, the Ministry of Health leveraged the resilient health system and deployed efficient, all-inclusive, and integrated infectious disease management and infection prevention control strategies to maintain the provision of EHS while responding to the spread of infections.

Published: November 2023

Introduction
The sudden transition from face-to-face teaching to virtual remote education and the need to implement it during COVID-19 initially posed specific challenges to educational institutions. Identifying and understanding teachers’ experiences pave the way for discovering and meeting educational needs. This study explored faculty members’ teaching experiences during the COVID-19 pandemic.

Materials and methods
The qualitative descriptive design via conventional content analysis was used. It was conducted from January 13, 2020, to May 10, 2022. In-depth interviews (online and in-person) of ten faculty members, three managers, and one staff from Lorestan University of Medical Sciences were conducted. They were purposefully selected with maximum variation. Simultaneously with data collection, analysis was performed using the approach Graneheim and Lundman proposed (2004). Lincoln and Goba’s criteria were used to obtain the study’s rigor.

Results
Six categories emerged from the data: education in the shadow of the crisis, Challenges related to the teaching-learning process, Blurred boundaries between personal and professional lives, Positive consequences of e-learning, Trying to deal with the crisis, And dealing with the crisis.

Conclusions
Initially, teachers faced several challenges in the teaching-learning process and even in their personal life. However, with time, the actions of the teachers and the managers caused an increase in the quality of education. However, planning and foresight are needed in developing countries, including Iran, to appropriately face and optimally manage similar crises and move towards blended learning.
Competitive integrated employment for youth with disabilities: Aligning measurement with conceptualization using latent growth curve modeling
Authors: Mostafa Sayed , Wang Yudan Chen 
Published: November 2023

Purpose
Although existing research has generated a wealth of information related to employment for individuals with disabilities, a major limitation is that common measurements of employment do not fully capture the scope of the optimal outcome specified in public policies, namely, competitive integrated employment. Therefore, we aimed to describe the change and stability in multiple aspects of employment for youth with disabilities from high school age to mid-30s under the structural equation modeling framework.

Methods
We identified a sample of 1,921 youth with disabilities who were at least 18 years old in 2003 from the National Longitudinal Survey of Youth– 1997. We estimated a series of latent growth curve models to assess trajectories of job quality, indicated by hourly pay, and stability, indicated by weekly work hours, over a period of 15 years.

Results
Trajectories of job quality and stability did not covary or load on a common factor, but there was substantial variability within the sample in both the intercept and slope of these two constructs, which were best captured by a cubic growth curve, and partially explained by health condition and several demographic variables.

Conclusions
Competitive integrated employment comprises of multiple components which should ideally be considered along a time dimension. Future studies need to assess validity of the measurement model with a different sample and incorporate another important component of competitive integrated employment, that is, whether work is carried out at an integrated setting.

Published: November 2023

Background
The endothelial angiopoietin/Tie2 system is an important regulator of endothelial permeability and targeting Tie2 reduces hemorrhagic shock-induced organ edema in males. However, sexual dimorphism of the endothelium has not been taken into account. This study investigated whether there are sex-related differences in the endothelial angiopoietin/Tie2 system and edema formation.

Methods
Adult male and female heterozygous Tie2 knockout mice (Tie2+/−) and wild-type controls (Tie2+/+) were included (n = 9 per group). Renal and pulmonary injury were determined by wet/dry weight ratio and H&E staining of tissue sections. Protein levels were studied in plasma by ELISA and pulmonary and renal mRNA expression levels by RT-qPCR.

Results
In Tie2+/+ mice, females had higher circulating angiopoietin-2 (138%, p<0.05) compared to males. Gene expression of angiopoietin-1 (204%, p<0.01), angiopoietin-2 (542%, p<0.001) were higher in females compared to males in kidneys, but not in lungs. Gene expression of Tie2, Tie1 and VE-PTP were similar between males and females in both organs. Renal and pulmonary wet/dry weight ratio did not differ between Tie2+/+ females and males. Tie2+/+ females had lower circulating NGAL (41%, p<0.01) compared to males, whereas renal NGAL and KIM1 gene expression was unaffected.
Interestingly, male Tie2+/- mice had 28% higher renal wet/dry weight ratio (p<0.05) compared to Tie2+/+ males, which was not observed in females nor in lungs. Partial deletion of Tie2 did not affect circulating angiopoietin-1 or angiopoietin-2, but soluble Tie2 was 44% and 53% lower in males and females, respectively, compared to Tie2+/+ mice of the same sex. Renal and pulmonary gene expression of angiopoietin-1, angiopoietin-2, estrogen receptors and other endothelial barrier regulators was comparable between Tie2+/- and Tie2+/+ mice in both sexes.

Conclusion
Female sex seems to protect against renal, but not pulmonary edema in heterozygous Tie2 knock-out mice. This could not be explained by sex dimorphism in the endothelial angiopoietin/Tie2 system.
Factors associated with maternal health services utilization in Pakistan: Evidence from Pakistan maternal mortality survey, 2019
Authors: Midhet Farid , Hanif Mubashir , Khalid Samina Naeem , Khan Raheel Shahab , Ahmad Ikhlaq , Khan Shahzad Ali 
Published: November 2023

Background
This study investigates the factors associated with maternal health services utilization in Pakistan using two outcome indicators, ideal antenatal care (IANC), defined as the pregnant woman receiving all the essential services included in standard antenatal care, and skilled birth attendance (SBA).

Methods
This study used the Pakistan Maternal Mortality Survey 2019 data. The study utilized binary logistic regression models to investigate the adjusted association between the outcome variables, separately for IANC and SBA, and the independent variables, education, wealth, parity, and residence.

Results
Wealth showed a positive association with utilization of IANC (adjusted odds ratio [AOR] = 11.48, 95% CI = 7.76, 16.99) and SBA (AOR = 4.37, 95% CI = 3.30,5. 80). Maternal age was associated only with IANC for women aged 35 or more years (AOR = 1.31, 95% CI = 1.06, 1.62). Increased likelihood of utilization of IANC and SBA services was also observed for women with formal education. Women who had 3–5 previous live births had higher odds of using IANC and SBA than women who had 1–2 or more than five previous live births. Urban residency was not correlated with either IANC or SBA.

Conclusion
When compared to the wealthy and educated quintile, women in the lower wealth quintile and those without any formal education were less likely to utilize ANC and SBA services. A comprehensive and multipronged approach from the health and education sectors is needed to improve maternal health in Pakistan.
Is there a relationship between isometric hamstrings-to-quadriceps torque ratio and athletes’ plyometric performance?
Authors: Babakhani Farideh , Hatefi Mohamadreza , Balochi Ramin 
Published: November 2023

BackgroundThe application of the modified reactive strength index (RSImod) and isometric hamstrings to quadriceps (H:Q) torque ratio to monitoring the athletes’ performance is well established, but their relationship to each other still remains unknown. Therefore, the purpose of this investigation was to clarify whether there is a relationship between RSImodand the isometric H:Q torque ratio.MethodsTwenty-one male recreational athletes (age, 24.89 ± 4.46 years; weight, 74.11 ± 8.66 kg; height, 179.78 ± 6.76 cm) volunteered to participate in this research. Their isometric H:Q torque ratio via hand-held dynamometer and jumping performance variables during the stop jump (STJ), double leg-drop vertical jump (DL-DVJ), and single leg-drop vertical jump (SL-DVJ) tasks were measured. Also, the RSImodwas calculated by dividing the vertical jump height by the time to take-off. Pearson correlation coefficients were used to determine the relationship between the RSImodand jumping performance variables.ResultsThe result showed a significant strong positive relationship between the H:Q torque ratio and STJ performance based on the RSImod(p= .027, r = .724). Although, there was a moderate positive relationship between the H:Q torque ratio and jumping height of the STJ task, but it wasn’t statistically significant (p= .096, r = .588). Also, no significant relationship was found between the H:Q torque ratio and all jumping performance variables of the DL-DVJ and SL-DVJ tasks (p≥ .05).ConclusionThe current study exhibited that the isometric H:Q torque ratio correlates to STJ performance based on RSImodbut not to SL-DVJ and DL-DVJ. Notably, the difference in results between jumping tasks can be attributed to the complexity of the movement, which means that the RSImodis probably related to other factors. Therefore, the isometric H:Q torque ratio used to monitor the athletes’ performance couldn’t independently represent the jumping performance that is determined by RSImod.
Impact of opioid law on prescriptions and satisfaction of pediatric burn and orthopedic patients: An epidemiologic study
Authors: Armstrong Megan , Groner Jonathan I. , Samora Julie , Olbrecht Vanessa A. , Tram Nguyen K. , Noffsinger Dana , Boyer Edward W. , Xiang Henry 
Published: November 2023

Objectives
The objective of this study was to determine the reduction in prescribed opioid pain dosage units to pediatric patients experiencing acute pain and to assess patient satisfaction with pain control 90-day post discharge following the 2017 Ohio opioid prescribing cap law.

Methods
The retrospective chart review included 960 pediatric (age 0–18 years) burn injury and knee arthroscopy patients treated between August 1, 2015-August 31, 2019. Prospectively, legal guardians completed a survey for a convenience sample of 50 patients. Opioid medications (days and morphine milligram equivalents (MMEs)/kg) prescribed at discharge before and after the Ohio law implementation were collected. Guardians reported experience and satisfaction with their child’s opioid prescription at 90-days post discharge.

Results
From pre-law to post-law, there was a significant decrease (p<0.001) within the burn and knee cohorts in the median days (1.7 to 1.0 and 5.0 to 3.8, respectively) and median total MMEs prescribed (15.0 to 2.5 and 150.0 to 90.0, respectively). An interrupted time series analysis revealed a statistically significant decrease in MMEs/kg and days prescribed at discharge when the 2017 Ohio opioid prescription law went into effect, with an abrupt level change. Prospectively, more than half of participants were satisfied (72% burn and 68% knee) with their pain control and felt they received the right amount of medication (84% burn and 56% knee). Inpatient opioid use was not changed pre- and post-law.

Conclusions
Discharge opioids prescribed for pediatric burn and knee arthroscopy procedures has decreased from 2015–2019. Caregivers varied greatly in their satisfaction with pain control and the amount of opioid prescribed.
