Tariff Reductions

The study assesses the impact of tariff reductions on fluctuations in customs revenues in Vietnam. The collection of research data was based on the official sources, namely the Government’s Web Portal and the World Bank’s website, and took place between 2002 and 2017. This paper uses the LASSO (Least Absolute Shrinkage and Selection Operator) linear regression model to estimate and predict the relationship of data series, thereby drawing a regression equation to consider the impact of various factors on customs revenues. The results have proven that tariff reductions have no negative impact on customs revenues. When tariffs are reduced, import turnover increases, the level of compliance with tax laws by import-export enterprises increases, and smuggling and trade fraud decrease. Based on these conclusions, the paper proposes several policies aimed at ensuring future customs revenues in Vietnam. As follows from the findings provided below, in order to ensure customs revenues, the Vietnamese Government should introduce appropriate policies to improve the efficiency of customs management in Vietnam; envisage accurate planning and reasonable investment for the customs office in terms of facilities and human resources; establish reasonable non-tariff barriers to prevent fraud and abuse causing losses in customs revenues.

This paper examines the impact of the government and its agencies’ ownership on the effectiveness of one the main internal governance mechanisms, namely; board of directors, for a sample of 140 energy and petrochemical Saudi listed firms over 2012-2019. The Saudi Arabia provides an interesting context due to the domination of government-linked corporations’ ownership. This setting arranges for the impact of such ownership on the board of directors’ monitoring and advisory roles. The board of directors’ effectiveness is measured as an interaction term of the board size and meetings of the board of directors. The study finds that government-linked energy and petrochemical corporations’ ownerships are inversely related to the board of directors’ effectiveness. This result is sensitive to the measurement of the board of directors’ effectiveness as each variable consisting of the board of directors’ effectiveness was examined individually. The study also finds that government-linked corporations’ ownership had a strong negative impact on the board size. In contrast, the proposed model does not provide any evidence supporting the relationship of the government-linked corporations’ ownerships with board meetings. Overall, the evidence supports the substitution hypothesis on the relationship of government-linked corporations and board of directors’ effectiveness.

Abstract Administrators and supervisors face daily challenges over issues such as program funding, service fees, correct coding procedures, and the ever-changing healthcare regulations. Receiving equitable reimbursement for speech-language pathology and audiology services necessitates an understanding of federal coding and reimbursement systems. This tutorial provides information pertaining to two major healthcare coding systems and explains the relationship of these systems to clinical documentation, the Medicare Physician Fee Schedule and equitable reimbursement. An explanation of coding edits and coding modifiers is provided for use in those occasional atypical situations when the standard use of procedural coding may not be appropriate. Also included in this tutorial is a brief discussion of the impact that the Medicare Improvements for Patients and Providers Act of 2008 (HR 6331 Medicare Improvements for Patients and Providers Act [MIPPA], 2008) has had on the valuation of speech-language pathology procedure codes.

With the advent of the Internet and other digital technologies, contemporary businesses from all sectors are using social media for communication with consumers to engage them meaningfully with a brand. However, the use of social media for corporate social responsibility (CSR) communication is relatively new to the existing literature. Likewise, the impact of CSR communication through social media (CSR-S) on consumer emotions and behavior is, to date, underexplored. To address this, the present research aims to test the relationship of CSR-S on brand admiration and consumer purchase intention. The study proposes a direct relationship between CSR-S and purchase intention with a mediating effect of brand admiration. The data were collected from the banking consumers of Pakistan through a self-administered questionnaire. The authors distributed 800 questionnaires and received 463 questionnaires useful for data analysis, so the present research study response rate was around 59%. The data were analyzed using the structural equation modeling (SEM) technique in AMOS. The results revealed that CSR-S is positively related to purchase intention (β = 0.233). The results further showed that brand admiration partially mediates this relationship (β = 0.079). The survey respondents confirmed that their bank’s CSR communication helps enhance their purchase likelihood and their feelings of admiration for their bank. These findings will help policymakers at banking institutions better understand the importance of CSR communication on different social media platforms to achieve consumer-related outcomes.

AbstractObjective:This study aimed to determine the characteristics of tinnitus and tinnitus-related variables and explore their possible relationship with tinnitus-related handicap.Methods:Eighty-one patients with chronic tinnitus were included. The study protocol measured hearing status, tinnitus pitch, loudness, maskability and loudness discomfort levels. All patients filled in the Tinnitus Sample Case History Questionnaire, the Hyperacusis Questionnaire and the Tinnitus Handicap Inventory. The relationship of each variable with the Tinnitus Handicap Inventory score was evaluated by univariate and multivariate analyses.Results:Five univariables were associated with the Tinnitus Handicap Inventory score: loudness discomfort level, subjective tinnitus loudness, tinnitus awareness, noise intolerance and Hyperacusis Questionnaire score. Multiple regression analysis showed that the Hyperacusis Questionnaire score and tinnitus awareness were independently associated with the Tinnitus Handicap Inventory score.Conclusion:Hyperacusis and tinnitus awareness were independently associated with the Tinnitus Handicap Inventory score. Questionnaires on tinnitus and hyperacusis are especially suited to providing additional insight into tinnitus-related handicap and are therefore useful for evaluating tinnitus patients.

: Mitophagy plays an important role in maintaining mitochondrial quality and cell homeostasis through the degradation of damaged, aged, and dysfunctional mitochondria and misfolded proteins. Many human diseases, particularly neurodegenerative diseases, are related to disorders of mitochondrial phagocytosis. Exploring the regulatory mechanisms of mitophagy is of great significance for revealing the molecular mechanisms underlying the related diseases. Herein, we summarize the major mechanisms of mitophagy, the relationship of mitophagy with human diseases, and the role of traditional Chinese medicine (TCM) in mitophagy. These discussions enhance our knowledge of mitophagy and its potential therapeutic targets using TCM.
