The aim of project was to estimate relationship between physical activity, socio-economic conditions and BMI in sample of youth. A group consisted of 177 youth aged 14-16 years from two Warsaw junior high schools. The research included questionnaire information (socio-economic condition, lifestyle), measurements and tests of strength, agility, endurance, flexibility, and reaction time. To determinate the relationship between fitness and five factors stepwise multiple regression was used. The results showed that higher stress level had negative influence on grip strength of hand and agility of shuttle run. Exposure to smoking had a negative impact on result in grip strength of hand, endurance, and explosive power of the lower extremities. The number of people in family had negative effect on grip strength of hand, however lifestyle had a positive influence on number of sit-ups (abdominal muscular strength and endurance). In case of youth characterized by lower BMI category, weaker handgrip and increased spine flexibility were observed. Socio-economic conditions mentioned above had small influence on physical activity

<p>GIS-APPROACH application has allowed establishing that usual wheels of machine-tractor units carry out considerable influence on soil which exceeds visible borders of a track of wheels on the dimensions. This influence shows in augmentation of soil penetration resistance at 100-155 % in comparison with the control on depth of 0-10 cm and on 20-30 % on depth of 45-50 %. It is impossible to exclude that influence of wheels proceeds more deeply, than tests have been conducted. Critical for cultivated plants value of soil penetration resistance in 3 MPa under the influence of usual wheels of agricultural machinery comes nearer practically to a surface. Character of profile changes of hardness in various regions influences of wheels allows assuming the long season of a relaxation of soil for achievement of background values of soil penetration resistance. The further researches are necessary for an establishment of concrete indicators of dynamics. Negative influence of an overstocking does not confine only deterioration of conditions of growth of assemblages of rootlets of plants. Infringement of processes of moving of moisture in the soil, the accelerated evaporation and the slowed down processes of a filtration and an infiltration, destruction of modular frame, activization of erosive processes is possible. The understanding of these processes will give the chance volume understanding of real influence of running systems of machine-tractor devices on bedrock. Region intensive influence of dual wheels is circumscribed by the top soil layers (0-15 cm). The major feature of influence of dual wheels is absence of an overstocking above critical levels. It is impossible to exclude possible positive influence of moderate inspissations of soil under the influence of dual wheels for growth of agricultural crops and moisture conservation in soil. The cumulative negative effect on soil crossed vehicles traces is probable. The long season of a relaxation of soil after anthropogenic transformation can create a network of traces of vehicles in the field. In region crossings of traces negative effects considerably increase.</p> <p><em>Keywords: hardness of bedrock, GIS-TECHNOLOGY, technique influence</em></p>

The objective of this study was to analyze the effects of enterprise risk management (ERM) disclosure, leverage, firm size and profitability on firm value, which is proxied by Tobin’s Q. High corporate value can reflect the shareholders’ wealth. This study used the Indonesian Capital Market Directory (ICMD). The sample included 32 companies, chosen with nonprobability purposive sampling. This study used a quantitative approach with descriptive analysis methods and panel data regression to test hypotheses using the Eviews 10 application. ERM disclosure, leverage and profitability had a positive and significant influence on firm value, while firm size had a negative influence on firm value. The implication of this research is that where ERM has a positive influence on firm value, it is good for companies to increase ERM disclosure, because the company will be considered to have managed its risks well. Debt policy variables that are proxied by the Debt to Equity Ratio (DER) and profitability proxied by ROA had a positive effect on firm value. That is, a higher value of DER was followed by an increase in the percentage of Return On Assets (ROA), which increased the firm’s value. However, the company’s size variable which was proxied by Ln Total Assets had a negative effect on the value of the company, which indicated that investors dislike company assets that are too high and that are not offset by high profits. Keywords: enterprise risk management, leverage, firm size, profitability, firm value

This article examines the influence of populism on democratic quality in Latin America. It draws on findings of qualitative work on this question as well as a theoretical framework by Cas Mudde and Cristóbal Rovira Kaltwasser to test whether the assumptions and results of both are applicable in a comparative study. It is expected that populist actors have a negative impact on democratic quality when they are in government, but that they positively influence democratic quality when they are in opposition, where they can function as a corrective. Further, it is expected that these effects vary depending on the level of consolidation. A linear mixed-effects model and data from eighteen Latin American countries in the period 1995–2009 was used to evaluate the hypotheses. Generally, it was found that populist actors in opposition have a large positive influence on democratic quality and that populist actors in government have a negative influence.

People make trait inferences based on facial appearance, and these inferences guide social approach and avoidance. Here, we investigate the effects of textural features on trait impressions from faces. In contrast to previous work, which exclusively manipulated skin smoothness, we manipulated smoothness and the presence of skin blemishes independently (Study 1) and orthogonally (Study 2). We hypothesized that people are particularly sensitive to skin blemishes because blemishes potentially indicate poor health and the presence of an infectious disease. We therefore predicted that the negative effect of blemished skin is stronger than the positive effect of smoothed skin. The results of both studies are in line with this reasoning. Across ratings of trustworthiness, competence, maturity, attractiveness, and health, the negative influence of skin blemishes was stronger and more consistent than the positive influence of skin smoothness (Study 1). Moreover, the presence of skin blemishes diminished the positive effect of skin smoothness on attractiveness ratings (Study 2). In sum, both facial skin blemishes and facial skin smoothness influence trait impression, but the negative effect of blemished skin is larger and more salient than the positive effect of smooth skin.

The effect of money supply in enhancing economic growth in Nigeria and Ghana is investigated in this study. The major objectives of the study are to establish the joint and individual influences of money supply mechanisms on economic growth in Nigeria and Ghana. The study employs data from 2009 to 2018 and uses Ordinary Least Squares regression technique for analysis of the data. The findings reveal that broad money supply (M2) has an insignificant negative influence on RGDP in Nigeria, but in Ghana the impact is significant and positive. Broad money supply (M3) exerts insignificant positive influence on RGDP in Nigeria, but significant negative impact on RGDP in Ghana while credit to private sectors (CPS) has insignificant positive influence on RGDP in both Nigeria and Ghana. The study among others suggests that the Monetary Authorities in the two countries should come up with monetary policy strategies that will help drive the economy better and such policies should consider M2 and CPS more as their contributions are necessary for economic expansion that lead to more output and employment.

Systematic sport practice at younger ages positively influences body composition and maximum oxygen uptake (VO2max). On the other hand, its influence on maturation is still not consensual, and some studies claim a negative effect. Few studies have approached the differences in this influence according to different sport practices. The present study aims to analyse and compare the influence of karate and swimming practices, and the non-practice of sports, on body composition, VO2max and maturation in children and youth. Data were collected in 126 youth, 54 karate athletes, 36 swimming athletes and 36 participants with no sport practice (M=11.56±2.06 years). The type of sport practice had a different influence on body composition and VO2max, no negative influence was verified on maturation. In general, the sport practices revealed a positive influence in children and youth’s body composition. The karate practice provided significant lower body fat mass and higher lean mass in males. Swimming athletes revealed a significant higher VO2max compared to all other groups, while karate didn´t differed from no-practice group. The different influence of sport practices verified highlighted the importance of a multilateral development of children and youth by practising several sports.  Resumen: La práctica deportiva sistemática a edades más tempranas influye positivamente en la composición corporal y la absorción máxima de oxígeno (VO2max). Por otro lado, su influencia en la maduración aún no es consensuada, y algunos estudios afirman un efecto negativo. Pocos estudios se han acercado a las diferencias en esta influencia según las distintas prácticas deportivas. El presente estudio tiene como objetivo analizar y comparar la influencia de las prácticas de kárate y natación, y la no práctica de deportes, sobre la composición corporal, el VO2máx y la maduración en niños y jóvenes. Los datos fueron recolectados en 126 jóvenes, 54 atletas de kárate, 36 atletas de natación y 36 participantes sin práctica deportiva (M = 11.56 ± 2.06 años). El tipo de práctica deportiva influyó de manera diferente en la composición corporal y el VO2max, no se verificó influencia negativa en la maduración. En general, las prácticas deportivas revelaron una influencia positiva en la composición corporal de niños y jóvenes. La práctica del karate proporcionó una masa grasa corporal significativamente más baja y una masa magra más alta en los hombres. Los atletas de natación revelaron un VO2max significativamente más alto en comparación con todos los demás grupos, mientras que el karate no difirió del grupo sin práctica. La diferente influencia de las prácticas deportivas verificada resaltó la importancia de un desarrollo multilateral de la niñez y la juventud a través de la práctica de varios deportes.

In this paper, we document that corporate social responsibility (CSR) has a negative effect on brand value. Our results show that this negative relationship exists only in firms where investor interest and visibility is high. We show that the negative impact of CSR policies is experienced by firms with high analyst following, larger size, and high earnings. We argue that markets consider CSR activities as a form of corporate charity with no expectations of positive returns. As a result, CSR activities are unnecessary costs incurred by firms. These costs result is adversely affecting current and expected financial performances. Given that current and expected financial performances are important determinants of brand value, firms with more visible CSR activities experience decline in brand values. We also show that certain components of CSR policy – firms who audit their CSR report from external auditors, brands of firms who report their global CSR activities, and brands of firms who publish a separate CSR report – exert more negative influence on brand values than the other components. All of these components are also related to increasing visibility of CSR activities.

Social media is arguably the most influential force the 21st century has to offer more than the economy, politics, or anything in between; social media has greatly influenced everyone more than once. With a network of interconnected people so large over multiple platforms the force social media exerts over people has never been greater than now; social media has become the place where people share their opinions with the world for others to read, see, and hear. One example of its influence is the public perception on Covid-19, it increased the general fear of it and also decreased mental health among several users of social media; panic mostly spread among younger users, who expressed their concerns over social media (Ahmad & Murad, 2020). While social media applications have a positive influence, they also have a negative influence on their users, especially teenagers. A study conducted by Dr. Ghulam Shabir, Chairman of the Department of Media Studies at The Islamia University of Bahawalpur, found that out of 279 participants, 139 agreed and 85 strongly agreed that social media has a bad influence on the participants; however, they also found that 110 of the agreed and 63 strongly agreed that social media positively influenced them (2014). With many children trying to find who they are, this study stands to find whether social media has a positive or negative effect over the psychological well-being of students in Jose Marti Mast 6-12 Academy.

Live-stream shopping is developing rapidly, but the sales levels of live streaming products vary by different hosts. How to increase the sales volume of live streaming products has become a problem. Consumers’ purchase behavior in live streaming is determined by some subjective factors, and the persuasiveness of linguistic style affects this subjective judgment to a certain extent. Therefore, the persuasiveness of the hosts’ linguistic style will lead to changes in consumers’ purchase intentions, which will affect the sales volume of products sold in the live streaming. Based on Hovland’s persuasion model, Aristotle’s rhetoric skills, text analysis, Latent Dirichlet Allocation (LDA) topic extraction model and grounded theory, this study divides the host’s linguistic persuasive style in the social e-commerce environment into five types: appealing to personality, appealing to logic, appealing to emotion, appealing to reward, and appealing to exaggeration. Combined with the sales volume of the product, we establish a regression model, and obtain the influence results of the host’s various linguistic persuasive styles on the sales of live streaming products. The results show that: the linguistic persuasive style of appealing to personality has the greatest positive impact on the sales volume of live broadcast products, but the linguistic style of appealing to logic has a negative impact. Interestingly, the same linguistic style has different effects for different types of products: the linguistic style of appealing to exaggeration has a negative effect on the sales volume of apparel products, but it has a positive influence on the sales volume of digital electrical products. Therefore, different linguistic styles should be used for different product types.

Today the phenomenon of the influence of corruption to economic growth has been a fairly hot issue of debate, both theoretically and empirically. The research uses a data panel analysis with a Random Effect Model approach to determine if corruption has a negative impact on economic growth in 4 ASEAN countries over the period of 2004-2015. Analysis results show that variable corruption has a negative influence on economic growth despite being insignificant, while other variables that have a significant positive influence on economic growth are public investments. The results of this study confirm that the negative effects of corruption do not directly affect economic growth but rather lead to the inefficiencies of production processes and the misallocation of resources.
