Toward this end, we conducted a targeted meta-analysis of recent hiring experiments that manipulated both candidate gender and qualifications to couch our investigation within ongoing debates surrounding the impact of small amounts of bias in otherwise meritocratic hiring contexts.

The emergence of mobile health (mHealth) products has created a capability of monitoring and managing the health of patients with chronic diseases. These mHealth technologies would not be beneficial unless they are adopted and used by their target users. This study identifies key factors affecting the usage of mHealth apps based on user usage data collected from an mHealth app.

Design/methodology/approach
Using a data set collected from an mHealth app named mPower, developed for patients with Parkinson{\textquoteright}s disease (PD), this paper investigated the effects of disease diagnosis, disease progression, and mHealth app difficulty level on app usage, while controlling for user information. App usage is measured by five different activity counts of the app.

Findings
The results across five measures of mHealth app usage vary slightly. On average, previous professional diagnosis and high user performance scores encourage user participation and engagement, while disease progression hinders app usage.

Research limitations/implications
The findings potentially provide insights into better design and promotion of mHealth products and improve the capability of health management of patients with chronic diseases.

Originality/value
Studies on the mHealth app usage are critical but sparse because large-scale and reliable mHealth app usage data are limited. Unlike earlier works based solely on survey data, this research used a large user usage data collected from an mHealth app to study key factors affecting app usage. The methods presented in this study can serve as a pioneering work for the design and promotion of mHealth technologies.}, keywords = {Business Analytics}, author = {Li,Jiexun and Chang,Xiaohui} } @article {1969931, title = {Modeling and Regionalization of China{\textquoteright}s PM2.5 Using Spatial-Functional Mixture Models}, journal = {Journal of the American Statistical Association}, volume = {116}, year = {2020}, month = {2020}, pages = {116{\textendash}132}, keywords = {Business Analytics}, author = {Liang,Decai and Zhang,Haozhe and Chang,Xiaohui and Huang,Hui} } @article {1969946, title = {Noise Accumulation in High Dimensional Classification and Total Signal Index}, journal = {Journal of Machine Learning Research}, volume = {21}, year = {2020}, month = {2020}, pages = {1-23}, abstract = {Great attention has been paid to Big Data in recent years.

conduct simulations by varying sample size, signal strength, signal strength proportional to the number predictors, and signal magnitude with random forest classifiers.

Social support denotes to the interaction/communication with others, verbal or nonverbal, reducing the uncertainty or enhancing the self-perception of in control of one{\textquoteright}s own life (Albrecht and Adelman 1987). All participants of online communities are motivated by their desire of seeking social support. And such support occurs when community members form relational links among them and have interactions that intend to help (Heaney and Israel 2002). A network member can receive/send different types of social supports from/to others. Informational support transmits information and provides guidance related to the task/question a community member has (Krause 1986); emotional support expresses understanding, encouragement, empathy affection, affirming, validation, sympathy, caring and concern (House 1981; Wang et al. 2014); companionship or network support gives the recipient a sense of belonging (Keating 2013; Wang et al. 2014); and appraisal support enhances the self-evaluation of the recipient (House 1981). Studies have shown that people are usually motivated by their desire of seeking one or more types of social supports to participate in an online community (Goswami et al. 2010; Kanayama 2003; Pfeil 2007; Pfeil and Zaphiris 2009; Wright 2000; Xie 2008). And such social support can only be acquired during the interaction with others. For senior citizens, even though they can be greatly benefited from the social support received through participation, the obstacles they need to overcome in order to feel engaged could be larger than that of younger people (Charness and Boot 2009; Lee et al. 2011), especially when they come to the community for the first time. They could be easily overwhelmed by the content that has been generated by other existing members, finding it difficult to identify an appropriate member to initiate a meaningful interaction. It therefore is critical for an online community system to help senior participants identify other existing members who are more likely to supply the type of support they are seeking. While many previous studies have uncovered the variety factors, contextual (Pfeil and Zaphiris 2009; Wang et al. 2015; Xie 2008) or individual (Wang et al. 2014, 2015, 2012; Wright 1999), that impact the degree to which a senior citizen receives social support needed from an online community, it remains unclear what the characteristics of existing community members who are more likely to provide a new comer the kind of support, informational, emotional, companionship, or appraisal are. And the answer to this question may have significant academic and practical implications. This study thus proposes to fulfil the gap by utilizing data collected from a senior community website to investigate the links between the characteristics of existing senior members and the amount and the type of support they provided to new comers. }, keywords = {BIS, Business Analytics}, author = {Wang,Changyu and Zhu,Bin and Zuo,Meiyun} } @article {1970876, title = {Overview of business innovations and research opportunities in blockchain and introduction to the special issue}, journal = {Financial Innovation}, volume = {2}, year = {2016}, month = {2016}, keywords = {BIS, Business Analytics}, author = {Zhao,J.

Design/methodology/approach {\textendash} The authors investigate the price-volume relationship in the Chinese stock market before and after the Split Share Structure Reform using Shanghai Composite Index daily data from July 1994 to April 2013. Using a two-state Markov-switching autoregressive model and a modified two-state Markov-switching vector autoregression model, this study identifies bull or bear market and also examine the existence of regime-dependent Granger causality.

Findings {\textendash} Using a two-state Markov-switching autoregressive model, the authors detect structural changes in the market volatility due to the reform, and find evidence of a positive rather than an asymmetric price-volume contemporaneous correlation. There is a strong dynamic Granger causal relation from stock returns to trading volume before and after the reform regardless of the market conditions, but the causal effects of volume on returns are only seen in the bear markets before the reform. The model is robust when using different stock indices and time periods.

Originality/value {\textendash} The work is different from previous studies in the following aspects: most of the existing empirical literature focus on the well-developed economies, but our interest lies in the emerging Chinese market that has witnessed rapid growth in the past decade; in contrast to many works in the literature that examine the price-volume relationship during one market condition, the authors compare the relationship in a bull market with that in a bear market, using a two-state MS-AR model; the authors also employ a modified two-state Markov-switching vector autoregression model to examine the existence of regime-dependent Granger causality; as the most massive systematic reform for the Chinese stock market since its inception in 2005, the Split Share Structure Reform has a profound impact on the Chinese stock market, thus it is of vital importance to explore its effects on both the price-volume relationship and the market structure.}, keywords = {Business Analytics}, author = {Wang,Donghua and Lei,Man and Chang,Xiaohui} } @article {1970886, title = {Harnessing Internet finance with innovative cyber credit management}, journal = {Financial Innovation}, volume = {1}, year = {2015}, month = {2015}, keywords = {BIS, Business Analytics}, author = {Lin,Z. and Whinston,A.

Numerical air quality models are pivotal for the prediction and assessment of air pollution, but numerical model outputs may be systematically biased. An additive dynamic model is proposed to correct large-scale raw model outputs using data from other sources, including readings collected at ground monitoring networks and weather outputs from other numerical models. An additive partially linear model specification is employed for the nonlinear relationships between air pollutants and covariates. In addition, a multi-resolution basis function approximate is proposed to capture the different small-scale variations of biases, and a discretized stochastic
integro-differential equation is constructed to characterize the dynamic evolution of the random coefficients at each spatial resolution. An expectation-maximization algorithm is developed for parameter estimation and a multi-resolution ensemble-based scheme is embedded to accelerate the computation. For statistical inference, a conditional simulation technique is applied to quantify the uncertainty of parameter estimates and bias correction results. The proposed approach is used to correct the biased raw outputs of PM2.5 from the Community Multiscale Air
Quality (CMAQ) system for China{\textquoteright}s Beijing-Tianjin-Hebei region. Our method improves the root mean squared error and continuous rank probability score by 43.70\% and 34.76\%, respectively. Compared to other statistical methods under different metrics, our model has advantages in both correction accuracy and computational efficiency.}, keywords = {Business Analytics}, author = {Chang,Xiaohui and Chen,Yewen and Huang,Hui and Luo,Fangzhi} } @article {1984481, title = {$\#$SocialMediaWellness: Exploring a Research Agenda for Healthy Social Media Consumption}, journal = {Journal of Consumer Behaviour}, month = {2023 In Press}, keywords = {Business Analytics}, author = {Mertz,Breanne and Hass,Ashley and Anderson,Kelley Cours and Kaskela,Timothy and Zmich,Louis J.} } @article {1984486, title = {Special Purpose Mental Faculties Enable People to Effectively Answer Difficult Questions Using 3D Surface Graphs}, journal = {Decision Support Systems}, month = {2023 In Press}, keywords = {Business Analytics}, author = {Bina,Saman and Kaskela,Timothy and Jones,Donald and Walden,Eric and Graue,William} }
