Facebook moms help! What to buy for teething? The impact of social proof on consumer decisions of young mothers

Young mothers often look for solutions to problems related to childcare in groups associating other mothers on Facebook. One can find there not only numerous advice on, among others, nutrition, care or even treatment of infants, but also learn about various consumer trends. The aim of the article is to determine the role of social proof on groups of young mothers on Facebook in making consumer decisions. The research method used was the content analysis on a selected Polish group for young mothers on Facebook. It was hypothesized that social proof on Facebook groups is important in making consumer decisions of young mothers regarding their children. This applies to all products intended for young children, from care products, food products, toys, accessories for children, to medicinal products. Young mothers are often influenced by the prevailing trends and opinions of other members of the group for young mothers, who may be real mothers or – which one may not be aware of - representatives of various brands.

MODEL FOR EVALUATING THE INFLUENCE OF SOCIOLOGICAL INFORMATION ON HUMAN BEHAVIOR IN THE CONTEXT OF ITS INFORMATION SECURITY

Informational and psychological security is defined as a state of protection of an individual against influences capable of changing an individual's mental state and psychological characteristics against his will and desire, modifying his behavior and limiting the freedom to form his own position. In many cases, a person, having certain beliefs, acts "like everyone else" as a result. To explain this paradoxical phenomenon, it is necessary to investigate the mechanism underlying such behavior. For this purpose, the article considers a mathematical model of such a mechanism and evaluates its adequacy on individual real examples. The article examines the construction of a model of individual behavior under the influence of information, investigates a mathematical model of an individual's behavior by introducing quantitative assessments of his attitude to this state, investigates how an individual's behavior changes depending on the results of sociological research. The model of individual behavior under the influence of sociological information was considered, using the example of presidential elections, which provided an opportunity to investigate the developed model and analyze its reliability. The set of mutual influences on the personality, in which the problem of choice is solved, was studied, the social center that influences the making of the main decisions was considered, and the assessment of the role of television in the election campaign was determined. The provision of information security of the individual under the influence of sociological information, as well as the indicator of the dependence of family members on the opinions of other members and television, were studied, and the conditions under which it is possible to talk about the provision of information security of the individual were determined.

Coordinated Influence on the Opinions of Social Network Members

This paper studies a model of coordinated influence in a social network in which several members, called players, can jointly affect the opinions of other members, called agents, during a finite period of time. The model is treated as a cooperative dynamic game. The influence of players is expressed by declaring their opinions which are then considered and weighted by the agents to form their own opinions. The goal is to find the declared opinions of players focusing only on associated costs as well as on the average deviation of agents beliefs from the desired ones. Under coordination, the total costs of players are distributed using the Shapley value. If there is no information about the degrees of trust of agents to each other, these degrees are estimated using a centrality measure. Numerical simulation is performed for a well-known social network of a university karate club and for a lattice graph often used for modeling of spatial networks.

Анализ механизма коллективного поведения на основе нечеткой логики

In this paper an elementary mechanism of collective behaviour has been examined. This collective is considered as number of persons. Each member of the group makes a certain decision based on his own relation and the relations of other members. For instance, whether to engage in certain activity, whether to join to public organisation, whether to participate in the arrangements, to vote affirmatively etc. These cases can be united into one: the person should decide whether to go into certain state. Personal opinion of each member of the group and opinions of other members according to the problem can be inaccurate or fuzzy. In this paper this fuzziness is considered according the theory of fuzzy sets and modeling. The behaviour of several types of collectives is researched.
