    Intangible investments and voluntary delisting

    Drawing on a cost-benefit perspective, this paper explores the relation between information asymmetry and the decision to delist from stock exchanges during periods of uncertainty. Specifically, it investigates the role of firms’ intangible investments and the availability of alternative sources of finance on the decision to delist from foreign stock markets. There is a significant positive relationship between investments in intangible assets and firms’ decision to delist. Moreover, the evidence suggests that the positive intangibles-delisting nexus is accentuated by the availability of alternative sources of financing. Collectively, the results are consistent with the theoretical argument that the higher information asymmetry associated with intangible assets may increase the cost of staying listed on stock exchanges, particularly, in periods of uncertainty (captured in this study by accounting fraud allegations targeting cross-listed firms). The results have important implications for corporate managers, capital market participants, and policy makers

    Location Advantages, Governance Quality, Stock Market Development and Firm Characteristics as Antecedents of African M&As

    This study explores firm- and country-specific antecedents of African M&As. We use one of the largest datasets to-date consisting of 1,490 unique African firms (11,183 firm-year observations) from 1996 to 2012. Our results suggest that improvements in time-varying country-level factors, including location advantages (market size, human capital and efficiency opportunities), national governance quality, and stock market development are associated with an increase in the volume of M&A activity. Consistent with the resource-curse paradox, high resource endowments are not associated with increased levels of M&A. In support of the management inefficiency but contrary to the traditional firm size hypotheses, African targets are generally characterised by declining stock returns and accounting profitability but are more likely to be larger firms; suggesting the presence of information asymmetry concerns in their selection. Notwithstanding, we find evidence of heterogeneity across countries with inconsistent support for established target prediction hypotheses. A model which combines firm- and country- specific factors better explains observed variations in African M&A activity

    Whether mindfulness-guided therapy can be a new direction for the rehabilitation of patients with Parkinson’s disease: a network meta-analysis of non-pharmacological alternative motor-/sensory-based interventions

    BackgroundThe treatment for Parkinson’s disease (PD) consumes a lot of manpower and financial resources. Non-pharmacological alternative motor-/sensory-based interventions are optimized for the rehabilitation of PD patients. Mindfulness-based therapy shows ideal efficacy, but the diversity of the therapy brings difficulties to the selection of clinicians and patients.MethodsNetwork meta-analysis in the Bayesian framework was used to evaluate the efficacy of non-pharmacological alternative motor-/sensory-based interventions in improving motor and non-motor symptoms in PD patients.ResultsA total of 58 studies (2,227 patients) were included. Compared with the non-intervention group, qigong was associated with improved outcomes in the Timed Up and Go (TUG) test (mean difference (MD) −5.54, 95% confidence interval (CI) −8.28 to −2.77), and UPDRS-I (MD −15.50, 95% CI −19.93 to −7.63). Differences between non-pharmacological alternative motor-/sensory-based interventions were not significant for PDQ-39, UPDRS-I, or UPDRS-II; however, qigong was superior to dance (MD −3.91, 95% CI −6.90 to −0.95), Tai Chi (MD −3.54, 95% CI −6.53 to −0.69), acupuncture (MD −6.75, 95% CI −10.86 to −2.70), music (MD -3.91, 95% CI −7.49 to −0.48), and exercise (MD −3.91, 95% CI −6.49 to −1.33) in the TUG test.ConclusionThis network meta-analysis supports mindfulness-based therapy (e.g., qigong, yoga, and Tai Chi) as a preferred non-pharmacological alternative motor-/sensory-based intervention for PD rehabilitation.Systematic review registrationhttps://inplasy.com/inplasy-2022-10-0109/, INPLASY2022100109

    BackgroundMany studies have investigated the efficacy of acupuncture in treating depression, but the mechanism of acupuncture for depression is still controversial and there is a lack of meta-analysis of mechanisms. Consequently, we investigated acupuncture’s efficacy and mechanism of depression.MethodsWe searched the Cochrane Library, PubMed, EMBASE, Web of Science. The SYRCLE Risk of Bias Tool was used to assess bias risk. Meta-analysis was performed using Stata 15.0 for indicators of depression mechanisms, body weight and behavioral tests.ResultsA total of 22 studies with 497 animals with depressive-like behaviors were included. Meta-analysis showed that acupuncture significantly increased BDNF [SMD = 2.40, 95% CI (1.33, 3.46); I2 = 86.6%], 5-HT [SMD = 2.28, 95% CI (1.08, 3.47); I2 = 87.7%] compared to the control group (p 2 = 86.8%] (p 2 = 84.5%], forced swimming test [SMD = −1.89, 95% CI (−2.55, −1.24); I2 = 76.3%], open field test (crossing number [SMD = 3.08, 95% CI (1.98, 4.17); I2 = 86.7%], rearing number [SMD = 2.53, 95% CI (1.49, 3.57); I2 = 87.0%]) (p ConclusionAcupuncture may treat animals of depressive-like behaviors by regulating neurotrophic factors, neurotransmitters, inflammatory cytokines, neuroendocrine system.Systematic review registrationhttps://www.crd.york.ac.uk/prospero/display_record.php?ID=CRD42023403318, identifier (CRD42023403318).</p
