Superior Knowledge, Price Discrimination, and Customer Inspection
Authors: Li Xi , Xu Zibin 
Published: March 2022

Firms in many industries obtain superior knowledge of customer preferences through industry experience or data analytics, whereas customers often need costly efforts to learn their match values. In this paper, we examine the situations under which a customer chooses whether to inspect upon observing her personalized price from a firm with superior knowledge. On the surface, it seems that the firm can use personalized prices to directly communicate the customers’ match value, and thus there is no need for customers to expend inspection efforts. However, we find that in equilibrium the firm may trick low-preference customers into overpaying more than their match value, even when the inspection cost is low. The opportunistic incentives induce customer suspicions, which may lead to excessive customer inspection that would be avoided if the firm were not capable of price discrimination. Therefore, personalized pricing cannot obviate customer inspection. Since inspection cost raises a deadweight loss in social welfare, public policies that prevent firms from price-discriminating against customers may benefit both firms and customers.

Entrepreneurial Learning and Disincentives in Crowdfunding Markets
Authors: Xu Yan , Ni Jian 
Published: March 2022

Reward-based crowdfunding has enabled entrepreneurs to interact with consumers even before product launches. However, this market persistently suffers from a high failure rate; that is, entrepreneurs fail to launch and deliver their products as promised. We investigate the extent to which this high failure rate is because of information distortion—entrepreneurs have uncertainty about consumers’ evaluation of the new products. We model the product launch decisions of different types of entrepreneurs who raise funds through preselling on reward-based crowdfunding platforms and subsequently decide whether to continue with the product launch. To do so, we collect structured and unstructured data from Kickstarter’s digital video game category and classify attributes using supervised learning methods. We develop and estimate an integrated model of crowdfunding demand and entrepreneurs’ product launch decisions. We find that the information entrepreneurs gather from crowdfunding sales has sizable impacts on the product launch decisions of entrepreneurs with low managerial capital or new to the crowdfunding platform. Our counterfactual simulations suggest that platform policy regulating overfunded projects can reduce the product launch failure rate by about 13%. This paper was accepted by Matthew Shum, marketing.
Online Pricing with Offline Data: Phase Transition and Inverse Square Law
Authors: Bu Jinzhi , Simchi-Levi David , Xu Yunzong 
Published: March 2022

This paper investigates the impact of pre-existing offline data on online learning in the context of dynamic pricing. We study a single-product dynamic pricing problem over a selling horizon of T periods. The demand in each period is determined by the price of the product according to a linear demand model with unknown parameters. We assume that before the start of the selling horizon, the seller already has some pre-existing offline data. The offline data set contains n samples, each of which is an input-output pair consisting of a historical price and an associated demand observation. The seller wants to use both the pre-existing offline data and the sequentially revealed online data to minimize the regret of the online learning process. We characterize the joint effect of the size, location, and dispersion of the offline data on the optimal regret of the online learning process. Specifically, the size, location, and dispersion of the offline data are measured by the number of historical samples, the distance between the average historical price and the optimal price, and the standard deviation of the historical prices, respectively. For both single-historical-price setting and multiple-historical-price setting, we design a learning algorithm based on the “Optimism in the Face of Uncertainty” principle, which strikes a balance between exploration and exploitation and achieves the optimal regret up to a logarithmic factor. Our results reveal surprising transformations of the optimal regret rate with respect to the size of the offline data, which we refer to as phase transitions. In addition, our results demonstrate that the location and dispersion of the offline data also have an intrinsic effect on the optimal regret, and we quantify this effect via the inverse-square law.

Incentives, Wages, and Retention Among Direct Support Professionals: National Core Indicators Staff Stability Survey
Authors: Pettingell Sandra L. , Houseworth James , Tichá Renáta , Kramme Julie E. D. , Hewitt Amy S. 
Published: March 2022

AbstractDirect support professionals (DSPs) provide a range of supports in a variety of settings to people with intellectual and developmental disabilities (IDD) who count on these supports to live, work, and contribute in their communities. Despite this, high annual DSP turnover rates are problematic. DSP turnover is disruptive to people who receive supports as the lack of stable, reliable supports can negatively impact their important day-to-day outcomes (e.g., safety, community participation, and choice). Turnover also comes at a cost to provider organization in the hiring and training of new employees. To retain DSPs, organizations offer incentives (e.g., bonuses, retirement plans, health insurance). This study utilized National Core Indicators® (NCI®) Staff Stability Survey 2018 data to examine the relationships between wages, different types of incentives, including benefits (e.g., paid time off, access to health insurance, disability insurance, wage bonuses, health incentives programs, etc.) to annual turnover in participating states in the United States. Results indicated that incentives were not positively associated with DSP retention. Staff wages were the most notable factor associated with differences in DSP retention rates, along with the state in which the organization was located as well as organization vacancy rates.

Authors: Aleman-Tovar Janeth , Rios Kristina , Burke Meghan M. 
Published: March 2022

Abstract
Due to systemic barriers, Latinx parents of youth with intellectual and developmental disabilities (IDD) report having limited involvement in transition planning. To facilitate parent involvement in transition planning, it is critical to solicit feedback from Latinx families to inform the content and mode of a transition planning intervention. The purpose of this study was to explore Latinx parents' knowledge and preferred mode for a transition planning intervention. Twenty-eight Latinx parents of transition-aged youth with IDD completed surveys and focus groups. Participants reported wanting an intervention to focus on school-based transition planning and adult services; to a lesser extent, participants wanted information about natural supports. Regarding modality, participants desired in-person or online training (versus a brochure). Implications for research and practice are discussed.
Improving the mental health of women intimate partner violence survivors: Findings from a realist review of psychosocial interventions
Authors: Paphitis Sharli Anne , Bentley Abigail , Asher Laura , Osrin David , Oram Sian 
Published: March 2022

Background
Intimate partner violence (IPV) is highly prevalent and is associated with a range of mental health problems. A broad range of psychosocial interventions have been developed to support the recovery of women survivors of IPV, but their mechanisms of action remain unclear.

Methods
Realist review following a prospectively published protocol in PROSPERO (CRD42018114207) and reported using the Realist and Meta-narrative Evidence Synthesis: Evolving Standards (RAMSES) guidelines.

Results
Evidence was extracted from 60 reviews and triangulated in expert consultations. Mechanisms of action were categorised as either associated with intervention design and delivery or with specific intervention components (access to resources and services; safety, control and support; increased knowledge; alterations to affective states and cognitions; improved self-management; improved family and social relations).

Conclusions
Findings suggest that psychosocial interventions to improve the mental health of women survivors of IPV have the greatest impact when they take a holistic view of the problem and provide individualised and trauma-informed support.
Maternity waiting homes utilization and associated factors among childbearing women in rural settings of Finfinnee special zone, central Ethiopia: A community based cross-sectional study

Published: March 2022

BackgroundMaternity waiting home (MWH) is one of the strategies designed for improved access to comprehensive obstetric care for pregnant women living far from health facilities. Hence, it is vital to promote MWHs for pregnant women in Ethiopia, where most people reside in rural settings and have a high mortality rate. Therefore, this study aimed to assess MWHs utilization and associated factors among women who gave birth in the rural settings of Finfinnee special zone, central Ethiopia.MethodsA community-based cross-sectional study was conducted from 15thOctober to 20thNovember 2019 among women who gave birth in the last six months before data collection. Multistage random sampling was employed among 636 women from six rural kebeles to collect data through a face-to-face interview. Multivariable logistic regression analysis was fitted, and a 95% confidence level with a p-value <0.05 was used to determine the level and significance of the association.ResultsOverall, MWHs utilization was 34.0% (30.3% - 37.7%). The higher age (AOR: 4.77; 95% CI: 2.76–8.24), career women (AOR: 0.39 95% CI: 0.20–0.74), non-farmer husband (AOR: 0.28; 95% CI: 0.14–0.55), rich women (AOR:1.84; 95% CI: 1.12–3.02), living greater than 60 minutes far from a health facility (AOR: 1.80; 95% CI: 1.16–2.80), and four and more livebirths (AOR: 5.72; 95% CI: 1.53–21.35) significantly associated with MWHs utilization. The common services provided were latrine, bedding, and health professional checkups with 98.2%, 96.8%, and 75.4%, respectively. Besides, feeding service was provided by 39.8%. The primary reason not to use MWHs was the absence of enough information on MWHs.ConclusionOne-third of the women who delivered within the last six months utilized MWHs in the Finfinnee special zone. Our results support the primary purpose of MWHs, that women far from the health facility are more likely to utilize MWHs, but lack of adequate information is the reason not to use MWHs. Therefore, it is better to promote MWHs to fill the information gap among women with geographical barriers to reach health facilities.
The use of early warning system scores in prehospital and emergency department settings to predict clinical deterioration: A systematic review and meta-analysis
Authors: Guan Gigi , Lee Crystal Man Ying , Begg Stephen , Crombie Angela , Mnatzaganian George 
Published: March 2022

Background
It is unclear which Early Warning System (EWS) score best predicts in-hospital deterioration of patients when applied in the Emergency Department (ED) or prehospital setting.

Methods
This systematic review (SR) and meta-analysis assessed the predictive abilities of five commonly used EWS scores (National Early Warning Score (NEWS) and its updated version NEWS2, Modified Early Warning Score (MEWS), Rapid Acute Physiological Score (RAPS), and Cardiac Arrest Risk Triage (CART)). Outcomes of interest included admission to intensive care unit (ICU), and 3-to-30-day mortality following hospital admission. Using DerSimonian and Laird random-effects models, pooled estimates were calculated according to the EWS score cut-off points, outcomes, and study setting. Risk of bias was evaluated using the Newcastle-Ottawa scale. Meta-regressions investigated between-study heterogeneity. Funnel plots tested for publication bias. The SR is registered in PROSPERO (CRD42020191254).

Results
Overall, 11,565 articles were identified, of which 20 were included. In the ED setting, MEWS, and NEWS at cut-off points of 3, 4, or 6 had similar pooled diagnostic odds ratios (DOR) to predict 30-day mortality, ranging from 4.05 (95% Confidence Interval (CI) 2.35–6.99) to 6.48 (95% CI 1.83–22.89), p = 0.757. MEWS at a cut-off point ≥3 had a similar DOR when predicting ICU admission (5.54 (95% CI 2.02–15.21)). MEWS ≥5 and NEWS ≥7 had DORs of 3.05 (95% CI 2.00–4.65) and 4.74 (95% CI 4.08–5.50), respectively, when predicting 30-day mortality in patients presenting with sepsis in the ED. In the prehospital setting, the EWS scores significantly predicted 3-day mortality but failed to predict 30-day mortality.

Conclusion
EWS scores’ predictability of clinical deterioration is improved when the score is applied to patients treated in the hospital setting. However, the high thresholds used and the failure of the scores to predict 30-day mortality make them less suited for use in the prehospital setting.
Does grandchild care affect ageing satisfaction? Findings based on a nationally representative longitudinal study
Authors: Quirke Eleanor , König Hans-Helmut , Hajek André 
Published: March 2022

Objective
This study seeks to explore the association between grandchild care and Attitudes Towards Own Ageing, assessing whether the commencement of, or ceasing, grandchild care is associated with changes in grandparents’ perspectives on ageing.

Methods
Longitudinal data were drawn from a population-based sample of community-dwelling individuals aged ≥40 years in Germany. The Attitudes Toward Own Ageing subscale of the Philadelphia Geriatric Center Moral Scale (PGCMS) was used to measure Attitudes Towards Own Ageing. To determine whether respondents provided grandchild care, respondents were asked “I’d now like to go on to learn more about your activities and pastimes. Do you supervise other people’s children privately, e.g. your grandchildren, or the children of siblings, neighbors, friends or acquaintances?” Symmetric and asymmetric linear fixed effects regressions were used to assess within-person changes longitudinally.

Results
No statistically significant association between providing care for grandchildren and Attitudes Towards Own Ageing was found. Significant associations were found between Attitudes Towards Own Ageing and employment status. Namely, retirement was associated with more positive Attitudes Towards Own Ageing (β = 0.57, p < .001), as was not being employed (β = 0.57, p < .001). A significant association between self-rated health and Attitudes Towards Own Ageing was also found (β = -0.06, p < .001), with poorer self-rated health associated with more negative Attitudes Towards Own Ageing.

Conclusion
Our findings suggest that undertaking grandchild care does not shape Attitudes Towards Own Ageing. As our findings did not align with existing evidence on the associations between grandchild caregiving and measures of subjective ageing, further research is required.

Published: March 2022

Background
Menstrual products are necessary goods for women and people who menstruate to manage menstruation. Understanding the use and perceptions of menstrual products is key to promote menstrual equity and menstrual health. This study aimed at assessing the use and perceptions on menstrual products among women and people who menstruate aged 18–55 in Spain.

Methods
A mixed-methods study was conducted, including a cross-sectional study (N = 22,823), and a qualitative study (N = 34).

Results
Participants used a combination of products. Non-reusable products were the most used, while over half used reusable products. Usage changed when data were stratified by age, gender identification, completed education, country of birth and experiencing financial issues. It also varied between trans and cis participants. Menstrual products’ use also shifted based on experiences of menstrual poverty and access to information and products. Overall, reusable products were perceived to be more acceptable than non-reusable. Barriers to use the menstrual cup were also identified, including experiences of menstrual inequity (e.g., menstrual poverty, lack of access to information or menstrual management facilities).

Conclusion
Perceptions and choices of menstrual products need to be acknowledged, especially when designing and implementing menstrual policies to address menstrual inequity and menstrual health.

Published: March 2022

Masalah kemiskinan merupakan persoalan yang umum dihadapi oleh hampir semua wilayah di dunia termasuk Indonesia. Hasil kajian beberapa penelitian menunjukkan masalah kemiskinan umumnya berhubungan dengan beberapa faktor seperti kualitas sumber daya manusia dan pertumbuhan ekonomi. Dimana menurunnya kualitas sumber daya manusia dan pertumbuhan ekonomi pada suatu wilayah akan berdampak negatif naiknya tingkat kemiskinan, begitupula sebaliknya. Berdasarkan data dari BPS diketahui bahwa pertumbuhan ekonomi dan indeks pembangunan manusia di Indonesia terus meningkat, namun angka kemiskinan tidak turun secara signifikan. Oleh karena itu penelitian ini dilakukan dengan tujuan untuk mengetahui dan mendeskripsikan hubungan antara pertumbuhan ekonomi dan indeks pembangunan manusia dengan kemiskinan. Penelitian deskriptif ini menggunakan pendekatan kualitatif dengan mengumpulkan dan menganalisis data terkait kemiskinan, indeks pembangunan manusia dan pertumbuhan ekonomi di beberapa wilayah di Indonesia dan menjadikannya sebagai rujukan untuk memahami hubungan pertumbuhan ekonomi dan indeks pembangunan manusia dengan kemiskinan di Indonesia. Hasil penelitian menunjukkan bahwa meskipun angka pertumbuhan ekonomi dan indeks pembangunan manusia semakin baik, namun masih banyak indikator kemiskinan di Indonesia yang belum membaik. Hal tersebut berdampak lambatnya proses menurunkan angka kemiskinan di Indonesia. Untuk itu pendekatan multidimensi dalam mengukur kemiskinan diharapkan dapat mengatasi kekurangan tersebut dan mendukung terciptanya kebijakan yang lebih baik dalam mengatasi kemiskinan di Indonesia.
An empirical formula development to predict suspended sediment load for Khour Al-Zubair port, South of Iraq
Authors: Dakheel Ahmed A. , Al-Aboodi Ali H. , Abbas Sarmad A. 
Published: March 2022

AbstractA new formula for determining the suspended sediment load in Khour Al-Zubair port has been proposed using dimensional analysis. Six cross-sections have been identified in Khour Al-Zubair port at Basrah province, South of Iraq for the purpose of conducting field measurements during the two tidal periods (Neap and Spring). The study involved taking field measurements of the hydraulic and fluid properties, and sediment sampling by section every 2 h to get effective parameters used for developing empirical formula. These parameters include the density of sediment (ρs), mean velocity (V), hydraulic radius (Rh), fall velocity of the particle (Ws), median grain size (d50), the salinity of water (S), water level (WL), the width of the estuary (B), specific gravity (Gs), maximum flow depth (Dmax), and kinematics viscosity (ν). The formula was developed using the statistical analysis using the SPSS program and dimensional analysis method. A good agreement between the loads computed by the suggested formula and the observed data has been attained based on the correlation coefficient value (R= 0.97). The results showed that the average total suspended sediment loads by using the proposed formula is 1288285.464 tons/year.
Future short-term estimation of flowrate of the Euphrates river catchment located in Al-Najaf Governorate, Iraq through using weather data and statistical downscaling model
Authors: Kareem Hayder H. , Alkatib Aseel A. 
Published: March 2022

Abstract
The issue of global warming has negatively affected the global climate, which caused a decrease in the amount of precipitation and a significant increase in temperatures and evaporation rates. Iraq suffers from poor rainfall, which exacerbates the problem of declining water levels in rivers and the drying up of some tributaries. The Euphrates river, which passes through the eastern side of the Al-Najaf Governorate, is the case study in the current research. A statistical downscaling model is created for rainfall data from 2010 to 2020 with the aim of predicting the future precipitation biennially from 2022 to 2028. The model is calibrated and reflects close results with observations with high accuracy and reliability. The future precipitation levels are transformed after multiplying these levels by the total surface areas of the Euphrates river and its tributaries, and the value of future flowrates to be added to the Euphrates river is estimated. The results showed that the Euphrates river will receive a flowrate of 1,535,945 m3 in 2026, which is the highest value when compared with the values of flowrate for the years 2022, 2024, and 2028, which are estimated at 1,475,072, 1,456,037, and 1,378,403 m3, respectively.
Cutting forces during drilling of a SiCp reinforced Al-7075 matrix composite
Authors: Ficici Ferit 
Published: March 2022

Abstract
In this study, an Al-7075 matrix alloy reinforced and by 5, 10, and 15 wt% silicon carbides were produced as a composite material using the stir casting method. An investigation of the hardness, density, and microstructure of the matrix alloy and the composite materials was conducted. The following instruments were used for the microstructure studies: optical microscope and scanning electron microscope (SEM). The machinability behavior of the produced composite materials was investigated by using the drilling method with a three-axis computer numerical controlled (CNC) milling center. High-speed steel (HSS) and titanium nitride (TN)-coated HSS drill bits were used in the machinability tests. As drilling process cutting conditions three different feed rates (FRs) of 0.05, 0.10, and 0.15 mm·rev−1 and three different cutting velocities (CVs) 15, 20, and 25 m·min−1 were applied. The effects of cutting conditions such as FR, CV, reinforcement phase ratio, and cutting tool type on cutting forces such as thrust force (TF) and torque (TQ) in the drilling process were studied in detail. According to the experimental results, TF and TQ decreased with the increase in the CV and increased with the increase in the FR.
