Social Media Influencers and Purchase Intention amongst Social Media Users in developing African economy

Background: Internet disruption has unprecedentedly made social media a global village and global digital market where business and customers interacts boundlessly. People’s interaction has far gone beyond boundary and businesses are seeing and harnessing these opportunities. Objective: This study investigated the effect of social media influencers on purchase intention among social media users. Method: The population of this study consist of active social media users in Anambra state. Sample size of 220 was arrived at using convenience sampling for infinite population. Reliability and validity test were done through construct Reliability and Discriminant validity respectively through smart- pls. Data was computed with SPSS version 24 and analysed with SEM via Smart-Pls. Result: The finding of this investigation showed that trustworthiness, attractiveness and influencer product match up has positive and significant effect on purchase intention respectively. Conclusion: More so, expertise does not influence purchase intentions. Finally, if there is need social media influencer, organizations should painstakingly seek influencers with high trust level among audience, highly attractive and it’s congruity with the intended promoted product.

Weakly-Interacting Bose-Bose Mixtures from the Functional Renormalisation Group

We provide a detailed presentation of the functional renormalisation group (FRG) approach to weakly-interacting Bose-Bose mixtures, including a complete discussion on the RG equations. To test this approach, we examine thermodynamic properties of balanced three-dimensional Bose-Bose gases at zero and finite temperatures and find a good agreement with related works. We also study ground-state energies of repulsive Bose polarons by examining mixtures in the limit of infinite population imbalance. Finally, we discuss future applications of the FRG to novel problems in Bose-Bose mixtures and related systems.

Dampak Usia, Struktur Keluarga, dan Tingkat Pendidikan Terhadap Perilaku Konsumen (Pengunjung) Destinasi Wisata di Kabupaten Tangerang

One of the important issues as a generator of the world economy is the tourism sector. It can reflected in fluctuations in the number of visitors to tourist destinations that tend to increase, so it becomes a discussion material by both researchers and policy makers. This study investigate the determinants of consumer behavior in determining tourist destinations in Tangerang Regency, namely age, family structure, and education level. This study used a cross-sectional survey approach and analyzed it with a binary probit regression model. Sample sizes were 395 respondents from an infinite population. The sampling technique used an accidental sampling technique. The primary data was obtained using questionnaires that had been tested for validity and reliability. Probit regression analysis showed that the age and level of education have a significant effect on consumer behaviour (visitors) in the selection of tourist destinations, while the family structure was not significant. The contribution of this research provides an alternative model of analysis and improves the consistency of the results of previous research. The current study also contributed to the importance of managing tourist destinations, in order to provide greater benefits for visitors and increased regional revenues from the retribution.

An Investigation of Cognizance and Approval of Green Advertising by Adolescents in Lucknow City

Today the major concern in the world is the environment. Corporate and government is trying to create awareness about the green environment among young consumers by using various tools. One of the important tools used to create awareness about the green environment is green advertising. The study is conducted with two objectives. The first objective of the study is to explore the awareness about green advertising among young consumers of Lucknow city and the second objective is to analyze the impact of green advertising on the behavior of young consumers in Lucknow city. The literature was collected using different databases such as EBSCO and Jstor. The sample size determined for the study is 384 respondents using the formula of an infinite population. Only 223 responses were received out of the targeted sample size of 384 respondents. The primary data collected using a structured questionnaire. The questionnaire was filled using convenience sampling. The statistical tool used for the analysis is descriptive statistics and one-way ANOVA. The results indicate that young consumers are aware of the green advertising in Lucknow city and green advertising has a significant impact on the behavior of young consumers of Lucknow City.

On inferring evolutionary stability in finite populations using infinite population models

Models of evolution by natural selection often make the simplifying assumption that populations are infinitely large. In this infinite population limit, rare mutations that are selected against always go extinct, whereas in finite populations they can persist and even reach fixation. Nevertheless, for mutations of arbitrarily small phenotypic effect, it is widely believed that in sufficiently large populations, if selection opposes the invasion of rare mutants, then it also opposes their fixation. Here, we identify circumstances under which infinite-population models do or do not accurately predict evolutionary outcomes in large, finite populations. We show that there is no population size above which considering only invasion generally suffices: for any finite population size, there are situations in which selection opposes the invasion of mutations of arbitrarily small effect, but favours their fixation. This is not an unlikely limiting case; it can occur when fitness is a smooth function of the evolving trait, and when the selection process is biologically sensible. Nevertheless, there are circumstances under which opposition of invasion does imply opposition of fixation: in fact, for the $$n$$ n -player snowdrift game (a common model of cooperation) we identify sufficient conditions under which selection against rare mutants of small effect precludes their fixation—in sufficiently large populations—for any selection process. We also find conditions under which—no matter how large the population—the trait that fixes depends on the selection process, which is important because any particular selection process is only an approximation of reality.

An interplay between attraction and repulsion in infinite populations

We propose and study a model describing an infinite population of point entities arriving in and departing from $$X=\mathbb {R}^d$$ X = R d , $$d\ge 1$$ d ≥ 1 . The already existing entities force each other to leave the population (repulsion) and attract the newcomers. The evolution of the population states is obtained by solving the corresponding Fokker-Planck equation. Without interactions, the evolution preserves states in which the probability $$p(n,\Lambda )$$ p ( n , Λ ) of finding n points in a compact vessel $$\Lambda \subset X$$ Λ ⊂ X obeys the Poisson law. As we show, for pure attraction the decay of $$p(n,\Lambda )$$ p ( n , Λ ) with $$n\rightarrow +\infty $$ n → + ∞ may be essentially slower. The main result is the statement that in the presence of repulsion—even of an arbitrary short range—the evolution preserves states in which the decay of $$p(n,\Lambda )$$ p ( n , Λ ) is at most Poissonian. We also derive the corresponding kinetic equation, the numerical solutions of which can provide more detailed information on the interplay between attraction and repulsion. Further possibilities in studying the proposed model are also discussed.

The Influence of Social Media Sites on Consumer Buying Behavior in Shoprite Nigeria Limited

Business organizations are continually searching for new ways to reach out to their consumers. Before, television, radio, and print are usually used by businesses to advertise their products. The coming of social media has shifted the way organizations interacting with their targeted audience. It has made social media an important tool for maintaining and creating a competitive advantage. Businesses today embrace the use of social media without paying adequate attention to silent issues concerning the usage of sites that can influence consumer buying behavior. The research aimed to examine the influence of social media sites on consumer buying behavior in Shoprite Nigeria Limited. The examined social media sites included Twitter, Facebook, Google+, blogs, and YouTube. The research was a descriptive design. The population was made up of consumers of Shoprite Nigeria Limited in Ibadan and Lagos. The sample size was 384 using Cochran's 1977 sample size formula for the infinite population. However, only 321 respondents filled and returned the questionnaires. A structured questionnaire was designed using a five-point Likert scale of agreement. Then, a hypothesis was tested using multiple regression analysis. The result shows that the null hypothesis is rejected. It implies that social media sites influence consumer buying behavior in Shoprite Nigeria Limited. It concludes that social media sites are important tools that can influence consumer buying behavior. It is recommended that the organization should invest more in social media sites to get in touch with their targeted audience.

INVESTIGATING THE EFFECT OF PRIDE, MINDFULNESS, GENERAL SELF-AWARENESS, EMOTIONAL SATISFACTION ON CUSTOMER CITIZENSHIP BEHAVIOR AMONG GREEN CUSTOMERS

Purpose of the study: The purpose of this study is to investigate the effect of pride, mindfulness, general self-awareness, emotional satisfaction on customer citizenship behavior among green customers. Methodology: The present study is descriptive research in terms of applied purpose and duration of data collection. Structural equation modeling with Warp PLS software was used for analysis. Due to the survey and the lack of research, a questionnaire was used to collect data. The statistical population included customers of Cinere green products. Since their number is unknown, the infinite population was considered, and Cochran's formula for the endless population was estimated at 384 people. Principal Findings: The results showed that pride has a positive and significant effect on the general self-awareness of green customers. Mindfulness has a substantial direct impact on the general self-awareness of green customers. The immediate effect of public awareness on the citizenship behavior of green customers was confirmed, and emotional satisfaction has a significant impact on the citizenship behavior of green customers. Finally, the mediating result of emotional satisfaction on the relationship between public self-awareness and citizenship behavior of green customers was confirmed. Applications of this study: This research can be used in psychology and sociology areas. Novelty/Originality of this study: to investigate the effect of pride, mindfulness, general self-awareness, emotional satisfaction on customer citizenship behavior among green customers.

Phase transition and universality of the three-one spin interaction based on the majority-rule model

In this work, we study the opinion dynamics of majority-rule model on a complete graph with additional social behavior namely anticonformity. We consider four spins with three-one interaction; three spins persuade the fourth spin in the population. We perform analytical and numerical calculations to find the critical behavior of the system. From both, we obtained the agreement results, e.g. the system undergoes a second-order phase transition and the critical point of the system only depends on the population number. In addition, the critical point decays exponentially as the number population increases. For the infinite population, the obtained critical point is [Formula: see text], which agrees well with that of the previous work. We also obtained the critical exponents [Formula: see text] and [Formula: see text] of the model, thus, the model is in the same universality class with the mean-field Ising.
