Safety driven intelligent autonomous vehicle for smart cities using IoT
Authors: Balachander K. , Venkatesan C. , R. Kumar 
Published: December 2021

Purpose
Autonomous vehicles rely on IoT-based technologies to take numerous decisions in real-time situations. However, added information from the sensor readings will burden the system and cause the sensors to produce inaccurate readings. To overcome these issues, this paper aims to focus on communication between sensors and autonomous vehicles for better decision-making in real-time. The system has unique features to detect the upcoming and ongoing vehicles automatically without intervention of humans in the system. It also predicts the type of vehicle and intimates the driver.

Design/methodology/approach
The system is designed using the ATmega 328 P and ESP 8266 chip. Information from ultrasonic and infrared sensors are analyzed and updated in the cloud server. The user can access all these real-time data at any point of time. The stored information in cloud servers is used for integrating artificial intelligence into the system.

Findings
The real-time sensor information is used to predict the surrounding environment and the system responds to the user according to the situation.

Practical implications
The system is implemented on embedded platform with IoT technology. The sensor information is updated to the cloud using the Blynk application for the user in real time.

Originality/value
The system is proposed for smart cities with IoT technology where the user and the system are aware of the surrounding environment. The system is mainly concerned with the accuracy of sensors and the distance between the vehicles in real-time environment.
A social epidemiological perspective on local tennis league participation: a multigroup moderated-mediation structural analysis using PLS-SEM
Authors: Kim Amy Chan Hyung , Du James , James Jeffrey 
Published: December 2021

Purpose The purpose of the current research was to examine the different relationships between individuals' sense of community in sport (SCS) cultivated by participating in local sport leagues, social support and health-related psychological outcomes (i.e. depressive symptoms and happiness) based on the participants' involvement level in the tennis league.Design/methodology/approach Using participants (n = 150) from local tennis leagues in the Southeastern region of the USA, the authors first conducted an instrument validation procedure to assess the psychometric properties of the included measures, and second, the authors analyzed the proposed multigroup moderated-mediation structural model using component-based partial least squares structural equation modeling with SmartPLS 3 (Ringle et al., 2015).Findings The results provide adequate evidence of reliability and validity for both the included reflective and formative constructs. Further, the findings of the proposed moderated-mediation structural model indicated that SCS was positively and significantly associated with social support and happiness while negatively related with depressive symptoms. Social support only mediated the relationship between SCS and happiness. The multigroup analysis results showed significant differences in the relationship between social support and happiness between the least involved group and more involved groups.Originality/valueThe findings of this study indicated that SCS experienced through participation in local sport leagues can develop both the extent and quality of supportive social relationships with other engaging members. One conclusion from the findings is recognizing a need to develop interventions to enhance SCS, social support and health-related psychological outcomes through local sport league participation.
Determinants of health and education equality: evidence from post-Soviet states
Authors: Panaro Angelo Vito 
Published: December 2021

PurposeThis article examines the determinants of social equality in the education and healthcare sectors in the 15 post-Soviet states. Focussing on regime type and civil society organisations (CSOs), it argues that countries where liberal principles of democracy are achieved or have a stronger civil society deliver a more equitable social policy.Design/methodology/approachThe empirical analysis rests upon a time-series cross-sectional (TSCS) analysis from 1992 to 2019. Data are collected from the Quality of Government (QoG) Dataset 2020 and the Variates of Democracy (V-DEM) Dataset 2020.FindingsThe findings demonstrate that while regime type only partially accounts for social equality, as electoral autocracies do not have more equitable social policy than close regime types and democracy weakly explains equality levels, the strength of CSOs is associated with more equality.Originality/valueThe article challenges dominant approaches that consider electoral democracy to be related to more equal social policy and demonstrates that de-facto free and fair elections do not impinge on social equality, while the strength of liberal and civil liberties and CSOs correlate with more equitable social policy.
To track or not to track: examining perceptions of online tracking for information behavior research
Authors: Makhortykh Mykola , Urman Aleksandra , Gil-Lopez Teresa , Ulloa Roberto 
Published: December 2021

PurposeThis study investigates perceptions of the use of online tracking, a passive data collection method relying on the automated recording of participant actions on desktop and mobile devices, for studying information behavior. It scrutinizes folk theories of tracking, the concerns tracking raises among the potential participants and design mechanisms that can be used to alleviate these concerns.Design/methodology/approachThis study uses focus groups composed of university students (n = 13) to conduct an in-depth investigation of tracking perceptions in the context of information behavior research. Each focus group addresses three thematic blocks: (1) views on online tracking as a research technique, (2) concerns that influence participants' willingness to be tracked and (3) design mechanisms via which tracking-related concerns can be alleviated. To facilitate the discussion, each focus group combines open questions with card-sorting tasks. The results are analyzed using a combination of deductive content analysis and constant comparison analysis, with the main coding categories corresponding to the thematic blocks listed above.FindingsThe study finds that perceptions of tracking are influenced by recent data-related scandals (e.g. Cambridge Analytica), which have amplified negative attitudes toward tracking, which is viewed as a surveillance tool used by corporations and governments. This study also confirms the contextual nature of tracking-related concerns, which vary depending on the activities and content that are tracked. In terms of mechanisms used to address these concerns, this study highlights the importance of transparency-based mechanisms, particularly explanations dealing with the aims and methods of data collection, followed by privacy- and control-based mechanisms.Originality/valueThe study conducts a detailed examination of tracking perceptions and discusses how this research method can be used to increase engagement and empower participants involved in information behavior research.
Understanding online review behaviors of patients in online health communities: an expectation-disconfirmation perspective
Authors: Chen Qin , Jin Jiahua , Yan Xiangbin 
Published: December 2021

PurposeAlthough online health communities (OHCs) and online patient reviews can help to eliminate health information asymmetry and improve patients' health management, how patients write online reviews within OHCs is poorly understood. Thus, it is very necessary to determine the factors influencing patients' online review behavior in OHCs, including the emotional response and reviewing effort.Design/methodology/approachBased on expectation-disconfirmation theory, this study proposes a theoretical model to analyze the effects of service quality perception (i.e. outcome quality and process quality perceptions) and disconfirmation (i.e. outcome quality and process quality disconfirmations) on patients' emotional response and reviewing effort. The authors test the research model by using empirical data collected from a popular Chinese OHC and applying ordinary least squares (OLS) regression and zero-truncated negative binomial (ZTNB) regression models.FindingsBoth service quality perception and disconfirmation have a positive effect on patients' positive emotional intensity in textual reviews, and disease severity enhances these relationships of process quality. Moreover, there is an asymmetric U-shaped relationship among service quality perception, disconfirmation and reviewing effort. Patients who perceive low service quality have higher reviewing effort, while service quality disconfirmation has the opposite relationship. Specifically, patients' effort in writing textual reviews is lowest when perceived outcome quality is 3.5 (on a five-point scale), perceived process quality is 4 or outcome quality and process quality disconfirmations are −1.Originality/valueThis study is the first to examine patients' online review behavior and its motivations and contributes to the literature on online reviews and service quality. In addition, the findings of this study have important management implications for service providers and OHC managers.

Authors: Giampaoli Daniele , Sgrò Francesca , Ciambotti Massimo , Bontis Nick 
Published: December 2021

Purpose
This study aims to provide empirical evidence on the linkage between knowledge management (KM), intellectual capital (IC), planning effectiveness (PE) and innovation performance in Italian small and medium-sized enterprises (SMEs).

Design/methodology/approach
Survey data from 172 Italian SMEs was collected through an online questionnaire and analyzed using structural equation modeling (partial least square).

Findings
Results show that KM practices have a positive direct impact on each IC component which influences PE. Finally, structural capital and PE have a positive direct impact a firm’s ability to innovate.

Research limitations/implications
For researchers, this paper fills an important gap in the academic literature by conceptualizing and empirically testing the link between IC and PE. The main practical implication of this study is that developing intangible resources is of particular importance for strategic decision-making in SMEs. The focus on Italian SMEs limits the generalizability of the results.

Originality/value
This study provides empirical evidence on how KM and IC interact and mutually drive PE. Second, results shed light on the importance of IC to enhance a firm’s ability to reach its goals. Finally, the focus on SMEs enriches the extant literature in the field confirming the vital role of KM and IC in managerial decision-making.
Factors affecting the frequency and contents of routine antenatal care in remote rural China in 2009–2016: An observational study
Authors: Feng Xing Lin , Wang Ying , Chen Zhengchao , Ronsmans Carine 
Published: December 2021

AbstractObjectiveWe assessed factors associated with the frequency and contents of antenatal care (ANC) in remote rural China, including the province of residence and individual‐level factors.DesignSurvey‐based cross‐sectional study.SettingFive provinces in remote rural China: Guizhou, Hunan, Jilin, Ningxia and Shaanxi.SampleA cohort of 3918 women with a live birth in 2009–2016.MethodsPoisson regression.Main Outcome MeasuresANC frequency: five or more visits, starting in the first trimester. ANC contents: coverage of six care components and overuse of ultrasound.ResultsThree‐quarters (72.9%) of women had five or more ANC visits, starting in the first trimester; 68.8% received all six care components and 94.5% had three or more ultrasounds. Only 30.9% of women sought ANC from township hospitals, paying between $3.80 and $25.80 per visit. ANC frequency and contents were associated with the socio‐economic characteristics of the women, but provincial effects were much greater, even after adjusting for individual factors. Women living in Guizhou and Ningxia, the two poorest provinces, with high proportions of ethnic minorities, were particularly underserved. Compared with women in Shaanxi, women in Guizhou were 33% (adjusted RR 0.67, 95% CI 0.61–0.74) less likely to receive five or more ANC visits, starting in the first trimester; women in Ningxia were 17% less likely (adjusted RR 0.83, 95% CI 0.76–0.90) to receive all six care components.ConclusionsThe province of residence was a stronger predictor of ANC frequency and contents than the individual characteristics of women in China, suggesting that strengthening the decentralised system of the financing and organisation of ANC at the province level is crucial for achieving success. Future efforts are warranted to engage subregional administrations.Tweetable AbstractThe province of residence was a stronger predictor of ANC frequency and contents than the individual characteristics of women.

Published: December 2021

AbstractObjectiveTo reweight the Agency for Healthcare Research and Quality Patient Safety for Selected Indicators Composite (Patient Safety Indicator [PSI] 90) from weights based solely on the frequency of component PSIs to those that incorporate excess harm reflecting patients' preferences for outcome‐related health states.Data SourcesNational administrative and claims data involving hospitalizations in nonfederal, nonrehabilitation, acute care hospitals.Study DesignWe estimated the average excess aggregate harm associated with the occurrence of each component PSI using a cohort sample for each indicator based on denominator‐eligible records. We used propensity scores to account for potential confounding in the risk models for each PSI and weighted observations to estimate the “average treatment effect in the treated” for those with the PSI event. We fit separate regression models for each harm outcome. Final PSI weights reflected both the disutilities and the frequencies of the harms.Data Collection/Extraction MethodsWe estimated PSI frequencies from the 2012 Healthcare Cost and Utilization Project State Inpatient Databases with present on admission data and excess harms using 2012–2013 Centers for Medicare & Medicaid Services Medicare Fee‐for‐Service data.Principal FindingsIncluding harms in the weighting scheme changed individual component weights from the original frequency‐based weighting. In the reweighted composite, PSIs 11 (“Postoperative Respiratory Failure”), 13 (“Postoperative Sepsis”), and 12 (“Perioperative Pulmonary Embolism or Deep Vein Thrombosis”) contributed the greatest harm, with weights of 29.7%, 21.1%, and 20.4%, respectively. Regarding reliability, the overall average hospital signal‐to‐noise ratio for the reweighted PSI 90 was 0.7015. Regarding discrimination, among hospitals with greater than median volume, 34% had significantly better PSI 90 performance, and 41% had significantly worse performance than benchmark rates (based on percentiles).ConclusionsReformulation of PSI 90 with harm‐based weights is feasible and results in satisfactory reliability and discrimination, with a more clinically meaningful distribution of component weights.
Lactobacillus alleviated obesity induced by high‐fat diet in mice
Authors: Song Wei , Song Chen , Li Li , Wang Tianyi , Hu Jinhong , Zhu Lina , Yue Tianli 
Published: December 2021

AbstractObesity is closely related to dyslipidaemia, diabetes and other metabolic syndromes. Long‐term consumption of a high‐fat diet (HFD) is an important risk factor that can lead to obesity. In the current research, three Lactobacillus strains, namely, Loigolactobacillus coryniformis subsp. torquens T3 (T3), Lacticasebacillus paracasei subsp. paracasei M5 (M5), and Lacticaseibacillus paracasei subsp. paracasei X12 (X12), were tested to determine their inhibitory effects on HFD‐induced obesity. The results showed that M5, T3, and X12 significantly decreased the body weight gain, Lee's index and adipose index. T3 showed significant effects on reducing serum TG levels to 0.92 mmol/ml and increasing HDL‐C levels to 2.18 mmol/ml. The M5 treatment significantly reduced the serum TG level and leptin content to 1.11 mmol/ml and 3.7 ng/ml, respectively, and it increased the HDL‐C level and adiponectin content to 2.35 mmol/ml and 7 ng/ml, respectively. M5 and T3 dramatically ameliorated hepatic steatosis in HFD‐treated mice by reducing the liver index, lipid droplet number in the liver and TC levels in the liver. Gene expression of PPAR‐γ and TNF‐α was notably downregulated and FAS was upregulated by T3 and M5 treatment. Additionally, administration of M5 and T3 modified the diversity of the gut microbiota with increased OTU number, ACE index, and Chao1, and decreased the Shannon index and the Bacteroidetes /Firmicutes ratio. Overall, our results indicate that Lactobacillus may be used to prevent obesity and gut dysbiosis.Practical ApplicationLactobacillus from traditional Chinese foods showed strong anti‐obesity effects on high‐fat diet‐fed mice through the regulation of adipocytokines. Additionally, administration of certain Lactobacilli modified the diversity of the gut microbiota. The results indicate that Lactobacillus may be promising functional materials in healthy foods.
Private contracts in two‐sided platforms
Authors: Llanes Gastón , Ruiz‐Aliseda Francisco 
Published: December 2021

AbstractWe study a platform that signs private contracts with sellers. Contractual secrecy implies interrelated hold‐up problems for buyers and sellers that reduce platform profits and welfare. By increasing its control over sellers' prices, the platform is able to increase price transparency and commit to not behaving opportunistically, which increases profits and welfare. Thus, policy prescriptions for dealing with contractual secrecy are reversed in the case of two‐sided platforms. We also find a platform may benefit from an erosion of its market power on one side of the market because this erosion may raise the surplus it offers the other side.
Effects of interventions to combat tobacco addiction: Cochrane update of 2019 and 2020 reviews
Authors: Livingstone‐Banks Jonathan , Lindson Nicola , Hartmann‐Boyce Jamie , Aveyard Paul 
Published: December 2021

AbstractAimsTo summarize evidence on tobacco addiction interventions published by the Cochrane Tobacco Addiction Group (CTAG) from 2019 to 2020.MethodsNarrative summary of all new and updated Cochrane Reviews published by CTAG in 2019 and 2020, outlining key results and promising avenues for future research.ResultsCTAG published six new reviews and updated 15 reviews. There is high‐certainty evidence that combining fast‐acting nicotine replacement therapy (NRT) with transdermal patches helped more people to quit than single‐form NRT [risk ratio (RR) = 1.25, 95% confidence interval (CI) = 1.15–1.36, 14 studies, n = 11 356; I2 = 4%] and moderate‐certainty evidence that using NRT before quitting can increase quit rates more than using NRT from quit day onwards (RR = 1.25, 95% CI = 1.08–1.44, nine studies, n = 4395; I2 = 0%). Reducing smoking in order to quit completely results in similar quit rates to abrupt quitting (RR = 1.01, 95% CI= 0.87–1.17; I2 = 29%; 22 studies, n = 9219; moderate‐certainty). Electronic cigarettes may help more people quit than NRT (RR = 1.53, 95% CI = 1.21–1.93; I2 = 0%; four studies, n = 1924; moderate certainty), nicotine‐free electronic cigarettes (RR = 1.94, 95% CI = 1.21–3.13; I2 = 0%; five studies, n = 1447; moderate‐certainty) and behavioural/no support (RR = 2.61, 95% CI = 1.44–4.74; I2 = 0%; six studies, n = 2886; very low‐certainty). Varenicline may help prevent relapse in abstainers (RR = 1.23, 95% CI = 1.08–1.41; I2 = 82%; 11 studies, n = 1297; moderate‐certainty), but behavioural support did not prevent relapse (RR = 0.98, 95% CI = 0.87–1.11; I2 = 52%; 11 studies, n = 5523; moderate‐certainty). Financial incentives increased quit rates in the general population (RR = 1.49, 95% CI = 1.28–1.73; I2 = 33%; 30 studies, adjusted n = 20 097; high‐certainty) and during pregnancy (RR = 2.38, 95% CI = 1.54–3.69; I2 = 41%; nine studies, n = 2273; moderate‐certainty). This overview also provides detail on a wider range of interventions.ConclusionsThere is high certainty that using nicotine replacement therapy from quit day increases smoking abstinence and no further research is required. Evidence is less certain that nicotine replacement increases abstinence when used in higher doses tailored to particular groups of smokers or use prior to quit day, and further research would be helpful. There is moderate‐certainty evidence to support the use of e‐cigarettes as cessation aids, but research on their role in preventing relapse would be particularly helpful.

AbstractBackground and AimsManagement of alcohol use disorder (AUD) could be enhanced by effective remote treatments. This study tested whether supplementing intensive outpatient programs (IOPs) with continuing care delivered via (1) telephone, (2) smartphone or (3) their combination improves outcomes relative to (4) IOP only. Continuing care conditions were also compared.DesignRandomized controlled trial of four groups with 3‐, 6‐, 9‐, 12‐ and 18‐month follow‐ups.SettingUniversity research center in Philadelphia, PA, USA.ParticipantsParticipants (n = 262) met DSM‐V criteria for AUD, were largely male (71%) and African American (82%).Interventions and ComparatorTelephone monitoring and counseling (TMC; n = 59), addiction comprehensive health enhancement support system (ACHESS; n = 68) and TMC + ACHESS (n = 70) provided for 12 months. The control condition received IOP only (TAU; n = 65).MeasurementThe primary outcome was percentage of days heavy drinking (PDHD) in months 1–12. Secondary outcomes were any drinking, any drug use, drinking consequences and quality of life.FindingsMean PDHD in months 1–12 was 10.29 in TAU, 5.41 in TMC, 6.80 in ACHESS and 5.99 in TMC + ACHESS. PDHD was lower in TMC [Cohen's d = 0.35, P = 0.018, 95% confidence interval (CI) = (−1.42, −0.20)], ACHESS [d = 0.31, P = 0.031, 95% CI = (−1.27, −0.06)] and TMC + ACHESS [d = 0.36, P = 0.009, 95% CI = (−1.40, −0.20)] than in TAU. Differences between TMC + ACHESS, TMC and ACHESS were small (d ≤ 0.06) and non‐significant. Findings were inconclusive as to whether or not the treatment conditions differed on PDHD at 18 months. A significant effect was obtained on any drinking, which was higher in months 1–12 in TAU than in TMC [odds ratio (OR) = 3.02, standard error (SE) = 0.43, 95% CI = (1.30, 6.99), P = 0.01] and TMC + ACHESS [OR = 2.43, SE = 0.39, 95% CI = (1.12, 5.27), P = 0.025). No other significant effects were obtained on other secondary outcomes during or after treatment.ConclusionsA telephone‐delivered intervention and a smartphone‐delivered intervention, alone and in combination, provided effective remote continuing care for alcohol use disorder. The combination of both interventions was not superior to either alone and effects did not persist post‐treatment.
