In this paper, we aim to study the impact of the shift in herding tendency on the diffusion of internet investment products in modular social networks. The epidemic spreading mechanism is applied and numerical analyses are conducted. The results suggest that the increase in herding tendency slows down the diffusion process and postpones the outbreak time of the diffusion, but such negative effects can be compromised when the independent acceptance willingness is high. When independent acceptance willingness is low, the limited extent of the herding tendency increases the diffusion scope. In addition, the expansion of the propagation lifetime or the increase of the clustering coefficient increases the threshold so that the herding tendency has an effect on outbreak size. Further, the growth of the herding propensity tends to magnify the positive influence of the clustering coefficient and the negative effect of the modularity.

The Impact

The impact of the Information and Technology (IT) sector on the countries’ innovation development has been recognized as crucial in prior and recent research studies. Moreover, firms’ innovativeness affects positively countries’ economies. Nevertheless, the global economic crisis of the last decade constituted a significant barrier to the development of country economies and had a negative effect on firms’ performance. Specifically, the negative consequences of the global crisis became harder for Southern Europe Countries. More specifically the Greek economy was suffered by an extended period of crisis with harder consequences than those of other European countries. The main purpose of this study was to examine the financial performance of Greek IT firms in the early years of crisis. Our findings have been relevant to those of previous studies which observed negative effects of the financial recession on firms profitability.

<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 aim of this paper is not only to determine and compare the nature of capital structure but also its effect on company performance of engineering industry of USA and Bangladesh. We utilize a panel data methodology based on a sample of 34 listed engineering companies of Bangladesh on Dhaka Stock Exchange (DSE) and a mixture of 34 (small, medium and large) engineering companies listed in NASDAQ in USA during the period of study from 2012 to 2019. Our empirical results indicate that the capital structure of engineering industry of USA and that of Bangladesh is different. Also, we demonstrate that capital structure has negative effect on company profitability of engineering industry of USA. Capital structure presents a negative effect on Earning per Share and Return on Assets (ROA) and positive influence on Return on Equity (ROE) and Tobin’s Q of engineering industry of Bangladesh. We conclude that the impact of capital structure on company’s profitability by only one sector and then compare the findings to know the real picture of the link. Investors, auditors, analysts and practitioners should consider many factors to examine the banking performance. Our results from this study may relate to Asian countries with similarities in engineering industry to that in Bangladesh.

Impact Of Pesticides

In recent decades an increase in the use of pesticides to protect plants from pests, diseases and weeds has been observed. There are many studies on the effects of various pesticides on non-target organisms. This review aims to analyze and summarize published scientific data on the effects of pesticides on the animal microbiome. Pesticides can affect various parameters of the animal microbiome, such as the taxonomic composition of bacteria, bacterial biodiversity, and bacterial ratios and modify the microbiome of various organisms from insects to mammals. Pesticide induced changes in the microbiome reducing the animal’s immunity. The negative effects of pesticides could pose a global problem for pollinators. Another possible negative effect of pesticides is the impact of pesticides on the intestinal microbiota of bumblebees and bees that increase the body’s sensitivity to pathogenic microflora, which leads to the death of insects. In addition, pesticides can affect vitality, mating success and characteristics of offspring. The review considers methods for correcting of bee microbiome.

Positive Effect

Recently, negative effects of the blasting operations and quantification of the seismic safety are regarded as very important technical problem in quarries. The impact of blasting operations is accompanied by both positive and negative seismic effects. For example, vibrations generated by explosion create very positive effect − when help to break the rocks, but, on the other hand, also result in negative effect − when affect constructions and natural environment in the vicinity of a blasting works site. If the vibrations are large enough, then the nearby objects could be damaged or destroyed. This article highlights the results of the blasting operation monitoring in limestone Lopušné Pažite quarry on Slovakia, which based on the rule that the negative effects depend on their range and strength. This method is applied in all quarries in Slovakia, which are close to settlements.

Social networks are a way of creating a virtual identity and entering into relationships with strangers in a series of interactions that were not known to a man before the existence of the Internet. Mobile phones and the virtual world often create a personality of a person that is not the same in the real world. It can be said that technology has changed the course of humanity and human consciousness and contributed to many changes in the mentality of society, especially among the youth. Children are often overwhelmed by materialism and jealousy, which further encourages them to become an unconscious, immoral and unambitious population. One of the negative effects of social networks is the abuse of privacy, which is also becoming a growing problem everywhere in the world and should not be ignored. However, a positive attitude should be maintained when it comes to social networks, because they facilitate communication, access to information and learning, greater availability of services and free advertising of some products or services. High school students use the Internet intensively every day, and the work raises the question of whether they use it constructively or destructively. The research was conducted in 2019, the population of high school students was observed and 100 students were included on the territory of Belgrade, Niš and Vitina.

Day By Day

Protein supplements are one of the most commonly consumed nutritional supplements, whether by professional athletes or amateurs, even by those who use them for aesthetic purposes instead of sporting ones. The thirst for becoming better is increasing day by day and so is the quest for competition. Sports have been one of the greatest of platforms to showcase one’s talent, thus leading to constant hustle for getting better day by day. To improve the performance, diet and physical appearance of the body i.e. muscle growth of athletes, sports nutrient products are developed. The use of these protein supplements in diet has increased the physiological requirement of protein but whether the use of these supplements is having positive or negative effect on the host is still a topic of debate for many. Large amount of protein derived constituents end up in the large intestine in case of high protein diets as compared to medium or low protein diets, leading to more bacterial amino acid metabolism in colon having positive as well as negative effects on the host. We, here, will try to summarize the impact of protein diet supplements on athletes.
