The Impact of Cash Flow Statement of Listed Firms on the Decision of Investors

This resarch is conducted for investigating the impact of cash flow statements on investors' decisions in an inefficient information market like Vietnam. Data were collected from the opinion of 150 investors in the stock market in which 75 investors received information on cash flow statement and 75 investors did not receive information of cash flow statement. We employ descriptive statistics and T-tests to examine the impact of cash flow statements on investors' decisions as well as investor confidence in the lack of information of cash flow statement. The results show that cash flow statement had no effect on investors' decisions but the lack of information on the cash flow statement reduced the confidence in making decisions. Based on the findings, some recommendations are given to investors who need to pay more attention to the cash flow statement in making decisions, and for firms that need to pay more attention to the supply information on cash flow statement.Keywords: Cash flow statement, Decision of the Investor, Inefficient marketDOI: 10.7176/RJFA/10-8-10Publication date: April 30th 201

Asymmetric Impacts of Public Debt on Economic Growth: Empirical Evidence From Vietnam

Purpose: The objective studies the influence of government debt on the expansion of the Vietnamese economy was the subject of the research presented in this article.   Theoretical framework: Most governments in developing nations have budget deficits due to excessive spending and inadequate revenue. When the government chooses to pay the budget deficit through borrowing, it incurs a liability known as public debt and public debt on economic growth.   Design/methodology/approach: In regression analysis involving time series data, if the regression model contains the variables' present values and the lagged values (past values), this model is known as the lagged distribution model. If the model's explanatory variables include one or more lagged values of the dependent variable, the model is called the autoregressive model. Nonlinear Auto Regressive Distributed Lag regression was applied.   Findings: The findings reveal that government debt has a considerable and disproportionate effect on sustained economic growth in the short and long run using a Nonlinear Autoregressive Distributed Lag (NARDL) model with quarterly data over twenty years beginning in 2000.   Research, Practical & Social implications: The results indicate a disproportional association between public sector debt levels and short- and long-term economic growth. The results are consistent with recent empirical studies showing a nonlinear relationship between some nations' public debt and economic development.   Originality/value: Government debt should support short- and long-term economic growth through funding production. Consequently, government debt should not burden the economy when the high amount of debt exceeds the capacity to repay

A secure image steganography based on JND model

Minimizing distortion produced by embedding process is very important to improve the security of hidden message and maintain the high visual quality of stego images. To achieve these objectives, an effective strategy is to perform pixel selection which is well-known as a channel selection rule. In this approach, a pixel associated with the smallest image degradation is chosen to carry secret bits. From these facts, in this paper, a new secure channel selection rule for digital images in spatial domain is designed and proposed. In this new approach, the modified matrix embedding method is utilized as data hiding method because it introduces more than one embedding change to be performed. This enables us to select a suitable pixel to embed message bits with less degradation yielded in a stego-image. In pixel selection of the proposed method, a just noticeable difference value and gradient value of a considering pixel are employed together. The experimental results (which were conducted on 10,000 uncompressed images) indicate that stego images of the proposed approach achieve a higher perceptual quality and security than those of the stego-images created by the previous approaches

Opening Sequences of Vietnamese Police-driver Traffic Enforcement Interactions

This paper examines the opening sequence of police-driver encounters at traffic stops when the police officers state the reasons for the stop, or request documents. Data include 30 video-recorded encounters between Vietnamese police officers and drivers, and are analysed using the methodology of Conversation Analysis. The findings have shown that police officers wield their judicial authority and institutional power right at the outset of the interactions by leading the interaction in a narrowly focused policing agenda, and taking different conversational paths. We argue that these differences in interactional orders may decrease driver co-operation and compliance with police officer directions, and be highly likely to increase recidivism. The present study may give police officers some new ideas about how to behave towards drivers during traffic stops, thus improving police-driver interactions in the Vietnamese policing context as well as in other cultural contexts in some respects

Evaluate the Results at Minimum 2-Years of Treating Rotator Cuff Tear by Arthroscopic Surgery

BACKGROUND: Rotator cuff tear (RCT) is a common injury of the shoulder, especially middle-aged people. Nonoperative treatment, cortisone injections are only effective at an early stage. Open surgery causes postoperative atrophy of the deltoid muscle, so results are limited. Arthroscopic rotator cuff repair surgery has been performed in Vietnam for about ten years, with many advantages such as the ability to accurately assess the lesions and less invasive procedure. In order to have a clearer view, we performed a mid-term assessment of the effectiveness of this surgery. AIM: Evaluate results over 2 years of patients with rotator cuff tears treated with arthroscopic surgery and their quality of life. METHOD: A group of 30 patients were diagnosed with RCT and surgery by arthroscopy to treat at Hanoi Medical University Hospital and Saint Paul Hospital between Jun 2015 and April 2017. The results of the surgeries were assessed by the degree of pain, muscle power, motion of the shoulder joint according to UCLA shoulder score. Evaluate the quality of life through the Rotator Cuff-Quality of Life (RC-QoL) index. RESULTS: The average age was 60.7 years. Female / male ratio was 1.3. Thirty-six months ± 6.41 was the average follow-up time (min 27 – max 50 months). The shoulder function is recorded according to UCLA has an average score of 30.9, therein good and excellent result were 90 %. The mean RC-QoL index was 91.5%. CONCLUSION: Treatment of RCT by arthroscopic surgery that has been evaluated for a minimum of 2 years follow-up showed good results and high quality of patient’s life
