Effects of Orienteering Game on Directional Relationships and Inhibitory Control in Children 7-8 Aged

The spatial orientation, ability is very important for the child, for the development of its executive functions such as inhibitory control and directional skills. In fact, the role of play as a locomotive for learning and motivation is very imperative in this age group. Our methodological choice consists of offering a teaching program around the orientation game (OG) that takes place in the school playground. The aim of this study was to examine the effect of OG on directional skills and inhibitory control. The assessment was respectively conducted by Topological and Directional Relation (RTD) and Stroop Color-Word Test -Victoria version (SCWT). Primary school students (N = 40; 7.3 years) participated in this study. They were divided into two groups: an experimental group (20 students) and a control group (20 students). The first group followed a 12-week orienteering game (OG) program with 3 sessions of 40 minutes per week and the second a regular physical education program. The results of the experimental group show a clear improvement in most of the study variables.

The Heuristic of Directional Qualitative Semantic: A New Heuristic for Making Decisions about Spinning with Qualitative Reasoning

Multifunctional Robot On Topological Notions (MROTN) is a research program that has as one of its goals to develop qualitative algorithms that make navigation decisions. This article presents new research from MROTN that extends previous results by allowing an agent to carry out qualitative reasoning about direction and spinning. The main result is a new heuristic, the Heuristic of Directional Qualitative Semantic (HDQS), which allows for selecting a spinning action to establish a directional relation between an agent and an object. The HDQS is based on the key idea of encoding directional information into topological relations. The new heuristic is important to the MROTN because it permits the continued development of qualitative navigation methods based on topological notions. We show this by presenting a new version of the Topological Qualitative Architecture of Navigation that uses the HDQS to address situations that require spinning.

EMPIRICAL ANALYSIS OF INDIA’S FOREIGN TRADE AND ECONOMIC GROWTH

The present study is an attempt to examine long run relationship among India’s GDP, Exports and Imports for which yearly time series data from 1995 to 2018 has been collected. Data for India’s GDP has been collected from RBI website and India’s export and import data has been collected form Ministry of Commerce and Industry website. The Augmented Dickey-Fuller unit root test for stationarity found that studied variables become stationary at first order of difference. While, Johnson cointegration test revealed long run cointegration between India’s GDP, exports and imports. The results of VECM Granger causality test exhibited bi-directional relationship between India’s GDP and India’s exports, whereas uni-directional relation has been found between India’s GDP and India’s imports. These results have significant implication for India’s export import policy and to achieve a target of $5 trillion economy till 2024-2025.

An Empirical Investigation of the income share of the middle class

The scientific evaluation of the relationship between growth, redistribution, and the income share of the middle class is still in its infancy. This article aims to investigate how the drivers of economic growth impinge on market income distribution and how the middle class has a role in deciding the level of redistribution. Our strategy is to dodge the reverse causality problem, stemming from the bi-directional relation between income distribution and growth, by exploiting the peculiar feature of different indicators of income dispersion focused on the middle income group. The findings reveal that market forces and redistributive policies are both pivotal in shaping the evolution of income dispersion and in particular the income share of the middle class, over the growth process. The ability of redistributive policies to counteract the ongoing increase in income inequality seems to depend not only on the political pressure exerted by an impoverishing median voter but also on the expansion of fiscal revenues after sustained Gross Domestic Product (GDP) growth.

Short-term contrarian and sentiment by traders’ types on futures markets

Purpose The purpose of this paper is to investigate whether the interaction between sentiments and past prices can lead to higher abnormal profit in futures markets. Such examinations allow the authors to relate the paper to the debate that focuses on examining the behavior of different types of traders in futures market, and who among these traders destabilize the markets. Design/methodology/approach First, the authors develop new dynamic strategies in US futures market that combine sentiment by type of traders based on trader position provided by the Disaggregated Commitments of Traders with short-term contrarian signals. Next, the authors adjust the abnormal profits to the CAPM model and Miffre and Rallis’s (2007) model. Finally, the authors use the Du (2012) decomposition methodology. Findings The main findings are that the abnormal profit is more pronounced when the authors combine past returns with lagged high producer/merchant/processor/user or low managed money sentiment. The results from swap dealer or other reportable groups show that there is no pervasive directional relation between their sentiment and contrarian profit. A further investigation of the sources of abnormal profits demonstrates that these profits survive even after the adjustment of obtained return to risk. Instead, these profits are mainly due to the overreaction to the news by irrational traders. Originality/value Based on behavioral finance theories, the authors conclude that producer, merchant, processor and user behave like irrational traders, while managed money traders behave like rational ones. Given that current regulatory proposes the limitation of speculation, the policy implications of these results are important. Therefore, these findings suggest that policy distinctions on trading motives may be more challenging to construct than ever.
