Reverse mortgages (RM) are an attractive tool to increase retirement incomes and to face the needs of health care for elderly people. The investor in the RM market faces several risks: longevity risk, as retirees’ life expectancy increases, interest rate risk, especially in the low-rate post-crisis period, property market risk, in the last stage of the current business cycle. In our pricing model we incorporate the overall risk of the RM, focusing on the feature of the developing Chinese market.

The article presents the data of the assessment of the physical development and functional state of highly qualified gymnasts engaged in rhythmic gymnastics. It was found that high-skilled gymnasts have heterogeneity of somatotypes determined according to the B. Heath-J. Carter scheme and heterogeneity of types of autonomous nervous regulation of heart rate variability, systolic, diastolic blood pressure and respiration, determined on the spiroarteriorhythmocardiograph device. Highly qualified gymnasts have vago- and normotonic types of regulation of heart rate variability; normal-sympathetic- and hypersympathicotonic types of regulation of the variability of systolic blood pressure and diastolic blood pressure, vagotonic type of regulation of the variability of the respiratory rhythm. Statistically significant differences gymnasts, successful in the medal standings at the international competitions and gymnasts participating, but not in high prizes in competitions, consist in the ability to resist fatigue while performing strenuous mental work (differences were revealed in 10-letter “Mental performance” at a constant speed (p > 0.0001), and 3-letter test (p > 0.001)), data stabilometric test “Target” indicator “Time stability on the left foot” (R > 0.039) with the advantage of a high performing gymnasts artists.

This paper presents a brief literature review of previous studies methodologies, models, and contexts in studying firms’ upgrading in Global Value Chains (GVCs). The key context of this paper is set within Fourth Industrial Revolution (4IR). Through the literature review, this paper offers to identify the opportunities of theoretical novelty and ways to elaborate on understanding firm dynamics in Global Value Chains in the context of 4IR. The approach based on Business Model (BM) innovations and new forms of organizing for business (such as platforms) is used to synthesize from previous research findings and build on to newer explanations of firms’ entry, learning, and upgrading within GVCs.

The Logit Model was employed to examine the impact of trade liberalization including the World Trade Organization (WTO) and ASEAN Economic Community (AEC) on SMEs performance. In addition, the second objective of this study is to investigate the factors affect the SMEs performance. The result shows that AEC awareness has significant impact on SMEs performance. In addition, there are various factors affect SMEs performance. Therefore, Lao government should promotion of implementation of AEC.

Chinese small towns are usually developed with single core industry, and the urban brand is the identity of a town that formed with the development of its industry. However, when the core industry representing its urban brand is facing a changing situation or market, will the brand be a motivation or an obstruction of the development of a town? The paper combined top-down and bottom-up research method to study the function of the urban brand in Wangqingtuo town in Tianjin, China. We studied over 400 samples (including government staff and town citizens) to make questionnaire investigation about the town’s branding. And we found that the solidified urban brand is a complicated emotional symbol for both government and citizens. The town has demand of exploring and developing new dominant industry, and it has the expectation to keep branding and upgrade its current core industry.

The introduction and implementation of finansijsko upravljanje i kontrola (FUK, financial management and control [FMC]) in Federation of Bosnia and Herzegovina (FBiH) aims to incorporate a modern public internal financial control (PIFC) system into traditional public resources management models. This area is one of the reform areas in which Bosnia and Herzegovina (BiH) is obliged to harmonize the legislative framework and practice with the good practices and regulations recommended by the European Commission. The establishment and development of the PIFC are also an obligation of Bosnia and Herzegovina established by the Stabilization and Association Agreement between the European Community and the member states, of the one part, and Bosnia and Herzegovina, of the other part. The public internal financial control (PIFC) system focuses on enhancing transparency, financial discipline, and dedicated use of public resources, that is, transparent, economical, efficient, and effective management of public resources, and control of the use of those resources. The topic of this paper is “financial management and control in the public sector” where the aim is to show, through the conducted theoretical research, the level of achievement of the establishment of this system in public sector institutions in BiH. The European Union wants to direct all potential member countries towards development of internal controls in the use of their own resources, but also to create a control environment that would ensure the dedicated use of EU funds. In Bosnia and Herzegovina, there is no single legal framework in terms of a single law governing public internal financial controls. The contents of the applicable legal provisions at all three levels (BiH, FBiH, and Republic of Srpska [RS]) are largely congruent thanks to the Coordination Committee of Central Harmonization Units (CHJs) in Bosnia and Herzegovina, through which the harmonization of regulations and practices in the development of public internal financial controls is ensured.
波斯尼亚和黑塞哥维那联邦(FBiH)引入和实施财务管理和控制(FUK, financial management and control [FMC])的目的是将现代公共内部财务控制(PIFC)系统纳入传统的公共资源管理模式。这一领域是波斯尼亚-黑塞哥维那(波黑)有义务使立法框架和做法与欧洲委员会建议的良好做法和条例相协调的改革领域之一。PIFC的建立和发展也是波斯尼亚-黑塞哥维那的一项义务，这是欧洲共同体与各成员国和波斯尼亚-黑塞哥维那之间的《稳定和联合协定》所规定的。公共内部财务控制(PIFC)制度侧重于提高公共资源的透明度、财务纪律和专用使用，即对公共资源进行透明、经济、高效和有效的管理，并对这些资源的使用进行控制。本文的主题是“公共部门的财务管理和控制”，其目的是通过进行的理论研究来展示波黑公共部门机构建立这一制度的成就水平。欧盟希望指导所有潜在成员国在使用本国资源时发展内部控制，但也要创造一种控制环境，确保专门使用欧盟资金。在波斯尼亚-黑塞哥维那，就管理公共内部财务控制的单一法律而言，没有单一的法律框架。得益于波斯尼亚和黑塞哥维那中央协调单位协调委员会(CHJs)，所有三个级别(波黑、波黑联邦和斯普斯卡共和国[RS])的适用法律条款的内容在很大程度上是一致的，通过该协调委员会，确保了公共内部财务控制发展中的法规和实践的协调。

In this paper, using data for the Bist 100 index, we investigate the presence of nonlinearities by employing several nonlinearity tests. The Brock, Dechert, and Scheinkman (BDS) and runs tests were first applied to the series to show an initial indication of nonlinearity. The findings for the BDS and runs test of randomness were followed by other sets of direct nonlinearity tests developed by White (1989), Terasvirta (1993), Keenan (1985), and Tsay (1986). Also, the Threshold Autoregression (TAR) test is employed as a final test to confirm the existence of nonlinearity in the Turkish stock exchange market. From the results of the nonlinearity test, it is concluded that the Bist 100 index is characterised by the presence of nonlinearities and cycles. This finding is in contrast with the efficient market hypothesis (EMH) implying that the Turkish stock exchange market is inefficient.
本文利用Bist 100指数的数据，通过几种非线性检验来研究非线性的存在性。首先将Brock, Dechert, and Scheinkman (BDS)和运行测试应用于该系列，以显示非线性的初始指示。在BDS和运行随机性检验的发现之后，White(1989年)、Terasvirta(1993年)、Keenan(1985年)和Tsay(1986年)开发了其他组直接非线性检验。此外，采用阈值自回归(TAR)检验作为最终检验，以确认土耳其证券交易所市场存在非线性。非线性检验结果表明，Bist 100指数具有非线性和循环的特征。这一发现与有效市场假说(EMH)相反，该假说暗示土耳其证券交易所市场效率低下。
