Heuristic biases and investment decisions: multiple mediation mechanisms of risk tolerance and financial literacy—a survey at the Tanzania stock market
Authors: Kasoga Pendo Shukrani 
Published: October 2021

PurposeThe purpose of this research is to examine the effect of heuristic biases on investment decisions through multiple mediation mechanisms of risk tolerance and financial literacy in the Tanzanian stock market.Design/methodology/approachA sample of 316 individual investors in the Tanzanian stock market was obtained through questionnaires. The data were analyzed using structural equation modeling (SEM).FindingsThe findings show that financial literacy mediates insignificantly the effects of overconfidence, availability, anchoring and representativeness heuristics on investment decisions. Further, financial literacy does not influence the effect of risk tolerance and investment decisions. Risk tolerance is confirmed as a positive mediator of overconfidence, availability, anchoring and representativeness heuristics in investment decisions. Also, the study shows that overconfidence exerts a stronger influence on investment decisions, followed by availability, representativeness, risk tolerance, anchoring and financial literacy.Research limitations/implicationsThe study deals with real investors. Therefore, it uses fewer items to measure the constructs in order to avoid respondent bias. Further research could examine the effects of heuristic biases on investment decisions by adding or modifying the items of particular constructs and studying institutional investors.Practical implicationsThe findings can help individual investors to analyze and evaluate their behavior toward stock selection. Securities institutions can use this research to understand investors' behavior, evaluate future market trends and provide advice to the investors.Originality/valuePrevious studies have examined the impact of heuristics on the investment decisions of individual investors. The unique empirical analysis developed in this paper is that it examines the multiple mediation mechanisms of risk tolerance and financial literacy with respect to heuristic biases and investment decisions in the Tanzanian stock market.

Published: October 2021

PurposeAlthough academics and retail managers share a common belief that crowded stores generate more sales, there is a growing concern about the negative impact of retail crowding on customer relationship management (CRM). This research aims to understand the underlying processes driving the effect, and it explores potential moderators that may mitigate the negative effects on consumer satisfaction.Design/methodology/approachThis research employs a meta-analysis on retail crowding effects and potential moderators.FindingsThe integrative model of retail crowding reveals that social needs, crowd similarity, crowd expectation and uncertainty avoidance mitigate the negative retail crowding effects on satisfaction.Research limitations/implicationsThe authors advance the retailing literature by synthesizing recent studies on retail crowding. The findings also provide a clearer understanding of the mediating role of negative emotions in the relationship between retail crowding and satisfaction.Practical implicationsThis research offers guidance for retail managers on how to mitigate the harmful effects of crowding on customer satisfaction.Originality/valueThis research contributes to the retailing literature and offers guidance for retailers on how to mitigate the harmful effects of crowding on cvustomer satisfaction. Our moderation analyses provide insights into how and when crowding drives consumer satisfaction.

PurposeThe purpose of this paper is to investigate the impact of e-government usage on citizen engagement during the COVID-19 crisis in China, in relation to the mediating role of how citizens perceive the government. A model was also proposed to explain the relationship between e-government usage during the COVID-19 crisis and the mediating role that different perceptions of government play in influencing citizens level of engagement.Design/methodology/approachThe research model was tested empirically through a survey conducted online with 866 research participants, comprising of Chinese citizens from three large cities, which include Hefei, Shanghai and Nanjing.FindingsThe results in structural equation modeling showed that e-government usage has a significant positive influence on citizens' perception about trust in government, government transparency and government reputation but not significant influence on citizens' engagements. However, an indirect relationship was found out in the mediation analysis. There was also a significant relationship between the different perceptions of government. Mediation analysis showed that all the different perceptions of government mediate the relationship between e-government usage and citizens' engagements during the COVID-19 crisis. The single mediation pathways were found to be most effective mediators, identifying citizens' perception about trust in government to be the most effective mediator.Originality/valueThis study filled the gap in literature by examining how e-government usage by Chinese citizens during the COVID-19 crisis helped influence their attitude and behavior. Specifically, this study is one of the first to integrate citizens' usage of e-government and citizens' engagement through the different citizens' perceptions of government such as trust in government, transparency of government and government reputation in a non-liberal country.
Cracks in the mirror hypothesis: High specularity does not reduce detection or predation risk

Abstract

Some animals, including certain fish, beetles, spiders and Lepidoptera chrysalises, have such shiny or glossy surfaces that they appear almost mirror‐like. A compelling but unsubstantiated hypothesis is that a highly specular or mirror‐like appearance enhances survival by reflecting the surrounding environment and reducing detectability.

We tested this hypothesis by asking human participants to wear a mobile eye‐tracking device and locate highly realistic mirror‐green and diffuse‐green replica beetles against a variety of backgrounds in a natural forest environment. We also tested whether a mirror‐like appearance enhances survival to wild predators by monitoring the survival of mirror‐green and diffuse‐green replica beetles in a forested habitat and an open habitat.

Human participants showed no difference in the detection probability or detection latency of mirror versus diffuse replica beetles, indicating that mirror‐like appearance does not impair prey capture. The field predation experiment found no difference in survival between the mirror and diffuse replica beetles in forested environments. Similarly, there was no difference in survival when beetles were deployed in the open habitat where there is no background to reflect, indicating that predators detect and do not actively avoid mirror‐like beetles.

Our results suggest that a mirror‐like appearance does not reduce attack by predators. Instead, highly specular, mirror‐like surfaces may have evolved for an alternate visual function or as a secondary consequence of selection for a non‐visual function, such as thermoregulation.

Oral immunotherapy in children with a food allergy—Where do we stand? – Review
Authors: Pulik Kaja , Ruszczyński Marek , Krenke Rafał 
Published: October 2021

AbstractThe number of hospitalisations due to an anaphylactic reaction to food is continuously increasing. Therefore, there is an urgent need to seek effective therapy. Currently, the only way to treat food allergies is to avoid allergens and to administer intramuscular adrenaline if an accidental allergen intake occurs. The only causal therapeutic strategy is specific oral immunotherapy. An increasing amount of data confirms this therapy's effectiveness and safety, but the results remain inconclusive due to the lack of long‐term follow‐up. In this state‐of‐the‐art review, we briefly summarise the latest placebo‐controlled randomised controlled trials on oral immunotherapy (OIT) to treat food allergy. During the paper's review, we asked the following questions: does the therapy permanently increase the amount of allergen consumed without symptoms? Does it significantly increase or decrease the occurrence of severe systemic reactions – requiring the administration of adrenaline or hospitalisation? Many authors describe outcomes such as an increase in the amount of allergen that can be safely ingested; however, significant clinical benefits such as decreased hospitalisations or anaphylaxis incidence are rarely included in the results. To date, there is no unified protocol of therapy, which makes comparisons between studies difficult because of significant differences in types, doses, and routes of administration of the allergen, timeline for up‐dosing and maintenance, duration of the therapy, and primary outcomes of OIT.

AbstractObjectiveTo test whether there were fewer missed medical appointments (“no‐shows”) for patients and clinics affected by a significant public transportation expansion.Study settingA new light rail line was opened in a major metropolitan area in June 2014. We obtained electronic health records data from an integrated health delivery system in the area with over three million appointments at 97 clinics between 2013 and 2016.Study designWe used a difference‐in‐differences research design to compare whether no‐show appointment rates differentially changed among patients and clinics located near versus far from the new light rail line after it opened. Models included fixed effects to account for underlying differences across clinics, patient zip codes, and time.Data extraction methodsWe obtained data from an electronic health records system representing all appointments scheduled at 97 outpatient clinics in this system. We excluded same‐day, urgent care, and canceled appointments.Principal findingsThe probability of no‐show visits differentially declined by 0.5 percentage points (95% confidence interval [CI]: −0.9 to −0.1), or 4.5% relative to baseline, for patients living near the new light rail compared to those living far from it, after the light rail opened. The effects were stronger among patients covered by Medicaid (−1.6 percentage points [95% CI: −2.4 to −0.8] or 9.5% relative to baseline).ConclusionsImprovements to public transit may improve access to health care, especially for people with low incomes.
Blueberry juice: Bioactive compounds, health impact, and concentration technologies—A review

Published: October 2021

AbstractBlueberries are a popular fruit with an attractive flavor and color, as well as health benefits. These health benefits have been attributed to the important number of bioactive compounds in blueberries with activities such as antioxidant, antitumor, antimutagenic, and antidiabetic effects and the prevention of cardiovascular diseases. Despite these advantages, blueberries are only obtained fresh in certain seasons; therefore, the food and beverage industry transforms them into jelly, puree, or juice. However, the concentration process could help preserve the bioactive compounds of blueberry byproducts. Concentration technologies focus on the removal of excess water to increase the product stability and reduce storage and transportation costs by causing them to take up less space or as a pretreatment before dehydration. These technologies include evaporation, reverse osmosis, and freeze concentration, and each one has different effects on the efficiency, quality, and nutritional value of the final concentrates. However, freeze concentration and reverse osmosis produce a higher‐final quality concentrate than evaporation due to the use of low temperatures, which prevents the loss of thermolabile components such as bioactive compounds. Therefore, this review summarizes the impact of concentration technologies on the bioactive compounds and health benefits of blueberry juice.

ObjectivesWe aimed to evaluate the incidence, predisposing factors and impacts of polysubstance use (PSU) (ie, the concurrent use or abuse of two or more drugs or substances) in inflammatory bowel disease (IBD).MethodsData of patients enrolled between 1 January 2015 and 31 August 2019 from a single tertiary care referral center were retrospectively collected. Patients’ baseline and clinical characteristics and their antidepressant and/or anxiolytic medications were abstracted. Associations between PSU and patients’ characteristics were analyzed. Multivariate logistic regression models were fit, incorporating significant clinical factors.ResultsAltogether 315 patients with IBD (166 women, 149 men; 214 with Crohn's disease and 101 ulcerative colitis) were enrolled. Of them, 66 (21.0%) exhibited PSU (CD 21.5%, UC 19.8%); 37.5% had moderate to severe disease activity, 34.3% with extraintestinal manifestations (EIM), 41.6% with an anxious or depressed state and 69.8% had used healthcare resources in the prior 12 months. Moreover, 71.2% used two substances, while 27.3% used three substances. In the total cohort, EIM (odds ratio [OR] 1.97, 95% confidence interval [CI] 1.14‐3.34, P = 0.019) and antidepressant or anxiolytic use (OR 2.51, 95% CI 1.45‐4.39, P < 0.001) were positively associated with PSU on multivariate analysis. PSU was associated with increased rate of IBD‐associated imaging (57.6% vs 47.0%, P < 0.05).ConclusionsPSU is common in IBD. EIM, antidepressant and/or anxiolytic use and imaging studies were independently associated with PSU. This study reinforces the importance of screening patients with IBD for substance use, particularly those with EIM and using antidepressants and/or anxiolytics.

AbstractBackgroundThe adjusted‐Global Antiphospholipid Syndrome Score (aGAPSS) has been validated and used to predict antiphospholipid antibodies (aPL) related to vascular thrombosis (VT).ObjectiveTo validate aGAPSS for predicted aPL‐related VT and pregnancy complications (PC) in Thai systemic lupus erythematosus (SLE) patients.MethodsA cross‐sectional study was performed among Thai SLE patients with clinical manifestations; history of VT and PC, cardiovascular risk factors, and aPL profiles were collected. The aGAPSS was calculated from the sum of the risk factors (hyperlipidemia = 3.0, arterial hypertension = 1.0, anti‐cardiolipin antibody = 5.0, anti‐b2 glycoprotein I antibody = 4.0, and lupus anticoagulant = 4.0).ResultsOf 132 SLE patients, 12 (9.1%) had VT and 5 (4.1%) had PC. When comparing the aGAPSS (median; interquartile range [IQR]) of patients with events (VT and/or PC) (6.5; IQR 3.3‐9.0), VT (8.0; IQR 4.0‐9.0), arterial thrombosis (3.5; IQR 1.0‐5.8), and PC (9.0; IQR 8.0‐11.5), and the aGAPSS of patients without an event (3.0; IQR 0‐4.0), aGAPSS of patients with events was significantly higher, except in patients with arterial thrombosis. An aGAPSS of 4.5 or more was associated with risk of aPL‐related VT (sensitivity 71.4%, specificity 76.7%), and an aGAPSS of 6.0 or more was associated with risk of aPL‐PC (sensitivity 100%, specificity 84.0%).ConclusionThe aGAPSS could predict the risk of aPL‐PC and aPL‐related VT in Thai SLE patients.
Emerging role of TWEAK‐Fn14 axis in lupus, a disease related to autoimmunity and fibrosis
Authors: Xu Yuan , Wei Hui‐Ting , Jing Hao‐Yue , Tan Xiao‐Yang , Zhou Xiao‐Tao , Ma Yue‐Rong 
Published: October 2021

AbstractSystemic lupus erythematosus (SLE) is a chronic autoimmune disorder. Lupus nephritis (LN) is one of the severe clinical implications in SLE, and this was relates to fibrosis in the kidney. As an important marker in the tumor necrosis factor (TNF) superfamily, TNF‐like weak inducer of apoptosis (TWEAK) has been given much attention with respect to its role in regulating pro‐inflammatory immune response. Fibroblast growth factor‐inducible 14 (Fn14), the sole receptor for TWEAK, has been found expressed in different immune and non‐immune cells. TWEAK binds to Fn14, and then regulates inflammatory components production via downstream signaling pathways. To date, dysregulated expression of TWEAK, Fn14 has been reported in SLE, LN patients, and in vivo, in vitro studies have discussed the significant role of TWEAK‐Fn14 axis in SLE, LN pathogenesis, partly through mediating the fibrosis process. In this review, we will discuss the association of TWEAK‐Fn14 axis in lupus. Understanding the relationship will better realize the potential for making TWEAK‐Fn14 as a marker for the diseases, and will help to give many clues for targeting them in treatment of lupus in the future.

AbstractBackgroundThe benefits of mediastinal lymph node dissection (MLND) in colorectal cancer‐related pulmonary metastasectomy (PM) have been poorly reported. This study aimed to determine whether MLND affects survival in patients undergoing PM and to identify the prognostic factors for survival.MethodsWe retrospectively reviewed 275 patients who had undergone colorectal cancer‐related PM from January 2010 to December 2016. MLND was defined as the resection of at least six mediastinal lymph node stations according to the International Association for the Study of Lung Cancer criteria (N1, ≥3 stations; N2, ≥3 stations). The propensity score matching method was used to reduce bias.ResultsThirty‐three (12%) patients underwent MLND, and 13 (4.7%) patients had mediastinal lymph node involvement. This study showed no difference in 5‐year overall survival (no MLND, 52.7% vs. MLND, 53.5%; p = 0.81). On multivariable analysis, negative prognostic factors for overall survival were preoperative carcinoembryonic antigen (CEA) level (p < 0.001), a higher number of metastatic nodules (p < 0.001), metastatic nodule size ≥2 cm (p < 0.001), and lymph node involvement (p = 0.006).ConclusionsMediastinal lymph node involvement, preoperative CEA level, higher metastatic nodule number, and nodule size negatively affected survival whereas MLND in PM was not associated with survival.
The SEC Filing Review Process: A Survey and Future Research Opportunities*
Authors: Cunningham Lauren M. , Leidner Jacob J. 
Published: October 2021

ABSTRACTAs part of its goal to monitor and enhance the quality of information available to investors, the SEC reviews companies' filings to ensure compliance with applicable financial reporting and disclosure requirements. Increased public interest and the substantial costs for both the SEC in reviewing and the companies in responding have led to a rapidly growing body of accounting literature that examines the filing review process. We survey and comment on 80 published and unpublished academic research papers in this literature and identify significant gaps that future research should address. We also summarize the institutional features of the filing review process, aiming to inform future academic studies. Our survey should be of interest to both academics and market participants evaluating the effectiveness and efficiency of the filing review process.
