The Impact of the internet on Hungarian food consumers' ways of seeking information from the aspect of health awarness

One of the main components of healthy lifestyle is proper diet. When putting together one’s diet, lots of information are needed in order to be able to pick from various foods which contribute to converting to a healthier lifestyle and maintaining it. The main purpose of this study is to determine and show examples of the characteristics of online marketing which could help consumers in the conscious conversion to healthy lifestyle. Of the various factors, great emphasis is placed on online health-related information. Based on the research findings, it can be concluded that healthy lifestyle-related information has a significant role in online sources. Consequently, Internet can be regarded as a preferred source of information in terms of the conscious converting to healthy lifestyle

Képalapú közösségi média bejegyzések optimalizálási lehetőségei szemkamerás vizsgálattal az üdítőital-piacon = Optimizing options for image-based social media posts with eye camera testing in the soft drink market

A tanulmány az üdítőital-ipar két piacvezető vállalatának egy-egy Facebook bejegyzését veti alá szemkamerás vizsgálatnak. Az előre kiválasztott bejegyzések hasonló képi elemeket tartalmaztak: emberi arc, termék, márkajelzés és szöveg. A vizsgálathoz a Tobii Pro Fix szemkamerát használtuk. A kutatási minta elemszáma ideálisan 30 fő volt. A vizsgálatba bevont végzős középiskolai tanulók a Z-generáció tagjai, akik digitális bennszülötteknek tekinthetők. Így attitűdjük különösen fontos az online promóciók vizsgálata során. A kutatásba bevont tanulók a szemkamerás vizsgálatot követően részt vettek egy rövid kérdőíves megkérdezésben is, mely során a korábban látottakat kellett spontán és segítséggel visszaidézniük. Az önbevalláson alapuló megkérdezés alapján három csoportot alakítottunk ki a válaszadókból: „egészségtudatos”, „részben egészségtudatos” és „nem egészségtudatos”. A kutatás célja feltárni miként optimalizálható egy adott közösségi média platformon megjelenő üdítőitalokkal kapcsolatos bejegyzés. A kutatás eredményei közé sorolható az arc szerepének és irányának fontossága a tekintetvezetés szempontjából. Szintén érdemes kiemelni a „részben egészségtudatos” csoport nagyfokú figyelemét a képeken szereplő termékek frontoldali információi – a cukormentesség – iránt. Az említett elemek helyes alkalmazása kulcsfontosságú tényező lehet az optimális promóció létrehozásában. The study examines one Facebook post each from two leading companies in the soft drinks industry. The preselected posts contained similar visual elements: human face, product, branding and text. The Tobii Pro Fix eye camera was used for the study. The ideal number of items in the research sample was 30. The senior high school students included in the study are members of Generation Z, i.e. Internet natives. Thus, their attitudes are especially important when studying online promotions. The participating students also took part in a short questionnaire after the eye-camera study, during which they had to recall spontaneously and with help what they had seen before. Based on the self-report questionnaire, three groups of respondents were formed: 'health conscious', 'partially health conscious' and 'not health conscious'. The aim of the research is to explore how to optimise a soft drinks-related post on a given social media platform. The results of the research include the importance of the role and direction of the face in guiding the gaze. It is also worth highlighting the high level of attention paid by the "partially health-conscious" group to the front-page information - sugar-free - of the products featured in the images

Disappearance of stretch-induced wrinkles of thin sheets: a study of orthotropic films

A recent paper [Healey et al., J. Nonlin. Sci., 2013, 23, 777-805.] predicted the disappearance of the stretch-induced wrinkled pattern of thin, clamped, elastic sheets by numerical simulation of the Föppl-von Kármán equations extended to the finite in-plane strain regime. It has also been revealed that for some aspect ratios of the rectangular domain wrinkles do not occur at all regardless of the applied extension. To verify these predictions we carried out experiments on thin (20 µm thick adhesive covered) elastomer sheets with different aspect ratios under displacement controlled pull tests. We found that the wrinkled shapes are strongly influenced by the emerging orthotropy during the extension. To carry out quantitative comparisons we abandoned the assumption about material isotropy and derived the governing equations for an orthotropic medium. In this way we found good agreement between numerical simulations and experimental data. Analysis of the negativity of the second Piola-Kirchhoff stress tensor showed that the critical stretch for a bifurcation point at which the wrinkles disappear must be finite for any aspect ratio. On the other hand, there is no such a bound for the aspect ratio as a bifurcation parameter. Physically this manifests as complicated wrinkled patterns with more than one highly wrinkled zones on the surface in case of elongated rectangles. These arrangements have been found both numerically and experimentally. These findings also support the new, finite strain model, since the Föppl-von Kármán equations based on infinitesimal strains do not exhibit such a behavior

Wrinkling patterns of thin films under finite membrane strain

There is a wide interest in understanding phenomena related to thin and ultrathin surfaces, such as wrinkling, cresting or folding. The classical Föppl-von Kármán plate theory is extensively used to model such phenomena. Significant in-plane strains demand the extension of the classical FvK model. The extended theory predicts the disappearance of wrinkling in the case of rectangular, clamped, stretched sheets, which was verified on thin, polyurethane sheets. In this talk we further develop the model for curved surfaces and present problems, where the extension to the finite tangential strains is essential to investigate the arising wrinkling pattern. By numerical simulation of the governing nonlinear system of PDEs, we investigate the effect of the curvature of the reference configuration on the emerging wrinkling pattern and demonstrate that disappearance of wrinkles takes place on curved surfaces, as well

Comment on ``Magnetoresistance Anomalies in Antiferromagnetic YBa2_2Cu3_3O6+x_{6+x}: Fingerprints of Charged Stripes''

In a recent Letter Ando et al (cond-mat/9905071) discovered an anomalous magnetoresistance(MR) in hole doped antiferromagnetic YBa$_2$Cu$_3$O$_{6+x}$, which they attributed to charged stripes, i.e., to segregation of holes into lines. In this Comment we show that the experiments, albeit being interesting, do not prove the existence of stripes. In our view the anomalous behavior is due to an (a,b) plane anisotropy of the resistivity in the bulk and to a magnetic field dependent antiferromagnetic (AF) domain structure. It is unlikely that domain walls are charged stripes.Comment: 1 page, Accepted to PRL, Reply exists by authors of original pape

The online marketing possibilities and judgment of the domestic food-sector

The theme of my PhD research is the online marketing possibilities and judgment of the domestic food-sector. This article is based on the important bibliography of my research theme. I show the new categorization of the tools of marketing communication. I examine the recent years’ changes of the social approach and the interactivity. Based on the meeting of the Internet I separate our ages’ generations. Furthermore I examine the transformation of consumers into users in the digital environment. I prove the changes of the Internet’s penetration and the presence of enterprises in the Internet with statistic data. I touch the tendency of information searching in online environment. I present new methods to measure the online marketing activities’ return. Finally, I define my objectives of research based on my own experience and bibliography overview over and above I draw up my concrete future’s research which I separate seconder and primer section

A digitális élelmiszer-fogyasztó jellemzői = The characteristic of digital food consumer

The age of Internet had an especially great impact on consumers who represent one of the main actors on the market. Digitalization and the way of healthy lifestlye are the most important trends in our modern age. My main objectives of the research the mapping of the domestic digital food consumer relevance about online food behaviour depending on information gathering and shopping. I used two main methods of marketing research in the article: the primary and secondary ones. I analysed about the characteristic of one of my main cluster (expert internet users) of my previous representative research (1000 samples about attitudes of Internet using) in details with an online representative survey with 305 samples. The main viewpoint was the online food consumer attitudes. The elements of the pattern were chosen with the help of a filtering question, so the members of the final pattern were the representatives of the Generation Y (between 20 and 35), who have already been a majority in an survey as well in comparison with other age groups. I examined two validated model’s and my own statements. The first one is the Internet Information Search Model (ISM) and the second one is Online Consumer Style Inventory (O-CSI). I used various types of descripting statistics, cross-chart analyses, then made a factor- and cluster analysis. I created five well-differentiated segments. I can say that in a small pattern (305 samples), but minding the relevant statistical methods in a maximum way, I could define groups of consumers who – based on their features and content – represent the information search and the offline and online shopping in a quite new way

Pl\"ucker formulas using equivariant cohomology of coincident root strata

We give a new method to calculate the universal cohomology classes of coincident root loci. We show a polynomial behavior of them and apply this result to prove that generalized Pl\"ucker formulas are polynomials in the degree, just as the classical Pl\"ucker formulas counting the bitangents and flexes of a degree $d$ generic plane curve. We establish an upper bound for the degrees of these polynomials, and we calculate the leading terms of those whose degrees reach this upper bound. We believe that the paper is understandable without detailed knowledge of equivariant cohomology. It may serve as a demonstration of the use of equivariant cohomology in enumerative geometry through the examples of coincident root strata. We also explain how the equivariant method can be "translated" into the traditional non-equivariant method of resolutions.Comment: 29 pages; abstract made more precise, reference adde
