Decomposing the dynamics of heterogeneous delayed networks with applications to connected vehicle systems

Delay-coupled networks are investigated with nonidentical delay times and the effects of such heterogeneity on the emergent dynamics of complex systems are characterized. A simple decomposition method is presented that decouples the dynamics of the network into node-size modal equations in the vicinity of equilibria. The resulting independent components contain distributed delays that map the spatiotemporal complexity of the system to the time domain. We demonstrate that this new approach can be used to reveal new physical phenomena in heterogenous vehicular traffic when vehicles are linked via vehicle-to-vehicle (V2V) communication.Comment: The paper has been updated in response to referee comments. 5 pages, 2 figure

Social representation of competition and fraud

Good citizenship includes fair competitive strategies. Dishonest competitive behaviour – such as fraud – can reflect the absence of one main characteristic of good citizenship as mindfulness of laws and social rules. This article investigates the social representation of competition and fraud with two samples of students from business schools in France and in Hungary. Two complementary studies were carried out with P. Vergès’ associative method and C. Flament and M. L. Rouquette’s tools. The purpose of the first study (NFrench=104, NHungarian=107) is to characterize the central core of the respondents’ representation of both competition and fraud. On the basis of different cultural, historical and economic backgrounds, it was expected that the concepts of fraud and competition would overlap more extensively among Hungarian students than among French students. Results from the first study suggest only slight differences regarding the content of the representations; moreover, in both samples the representations of competition and fraud lacked significant overlap. Hungarian representations of competition and fraud are characterized by a lower level of coherence. Furthermore, academic cheating is mentioned more frequently by Hungarian students than by French students. Following the methodological guidelines of social representations, in order to confirm the results of the first study, a second investigation was carried out (NFrench=115, NHungarian=127) with an alternative associative method. These results confirmed the first study in terms of the content of the social representations and differences regarding coherence. Finally, in the case of Hungarian students a higher prevalence of reference to academic cheating, and links between fraud and competition were found. Hungarians’ competitive result orientation, linked social representations of competition and fraud via a higher prevalence of academic cheating which can refer to the weaker inclination of Hungarians in terms of rule keeping behaviours, which is one of the hallmarks of a good citizen

Are competition and extrinsic motivation reliable predictors of academic cheating?

Previous studies suggest that extrinsic motivation and competition are reliable predictors of academic cheating. The aim of the present questionnaire study was to separate the effects of motivation- and competition-related variables on academic cheating by Hungarian high school students (N = 620, M = 264, F = 356). Structural equation modeling showed that intrinsic motivation has a negative effect, and amotivation has a positive indirect effect on self-reported academic cheating. In contrast, extrinsic motivation had no significant effect. Indirect positive influence on cheating, based on some characteristics of hypercompetition, was also found, whereas attitudes toward self-developmental competition had a mediated negative influence. Neither constructive nor destructive competitive classroom climate had a significant impact on academic dishonesty. Acceptance of cheating and guilt has significant and direct effect on self-reported cheating. In comparison with them, the effects of motivational and competition-related variables are relatively small, even negligible. These results suggest that extrinsic motivation and competition are not amongst the most reliable predictors of academic cheating behavior

SZITUATÍV ÉS EGYÉNI TÉNYEZŐK HATÁSA EGY TESTMÓDOSÍTOTT MUNKATÁRS MEGÍTÉLÉSÉRE

A vizsgálat az arcon viselt testmódosítások munkahelyi megítélésére irányult. Arra kerestük a választ, hogy milyen tényezők hatnak egy az arcán testmódosítást viselő fiktív munkatárs megítélésére. A mintában 403 fő 206 férfi (kor M = 23,33; SD = 3,08) és 197 nő (kor M = 24,00; SD = 4,57) szerepelt. A vizsgálat során használt eszközök az Önbecsapás és Benyomáskeltés, a Big Five kérdőív udvariasság és nyitottság aldimenziójának tételei továbbá egy képzelt munkahelyi szituáció voltak. Az eredmények szerint az arcán testmódosított munkatársat kevésbé találják alkalmasnak olyan értékesítői munkára, amely megköveteli az ügyféllel való személyes kapcsolattartást. Azok a személyek, akik piercinget látható helyen viselnek, továbbá magasabb pontszámot értek el a benyomáskeltés, nyitottság és udvariasság skálákon jobban elfogadják az arcát testmódosításokkal díszítő személyt munkatársnak, mint az alacsonyabb pontszámot elérők és a piercinggel nem vagy kevésbé látható helyen rendelkezők. A jutalék elosztásának formája nem volt hatással a megítélésre. Annak ellenére, hogy a tetoválások és piercingek reneszánszukat élik mégis elmondható, hogy az arc testmódosítása kevésbé illik a professzionális vállalati szférába, abban az esetben, amikor az ügyféllel történő kapcsolattartás személyes interakciót követel meg

A Társas elutasításra való érzékenység kérdőív (Rejection Sensitivity Questionnaire) magyar nyelvre történő adaptációjának előzetes eredményei

Kutatásunk során magyar nyelvre adaptáltuk a Társas elutasításra való érzékenység (Rejection Sensitivity Questionannire, RSQ) kérdőívet. Célunk a kérdőív fak- torstruktúrájának feltárása és pszichometriai vizsgálata volt. Az RSQ kérdőív három faktorát különítettük el feltáró (EFA) és a konfirmatív (CFA) faktorelemzéssel: a Szülői elutasításra való érzékenység skálát, amely a szülőkkel kapcsolatos szituációkat tartalmaz, a Partner elutasítására való érzékenység skálát, amely a partner visszautasításától való szorongást méri és az Ismerősök elutasítására való érzékenység faktort, amely a távolabbi ismerősök elutasítására való érzékenység mérésére szolgál. A mérőeszköz struktúrája kiváló modell-illeszkedést mutatott, ezen kívül a kérdőív belső megbízhatósági mutatói szintén megfelelőnek bizonyultak. Az RSQ Magyarországon új mérőeszközt biztosít a társas elutasításra való érzékenység kutatására, valamint a kérdőív az iskola-, és szervezetpszichológiai munka, illetve klinikai felmérések során hozzájárulhat a gyakorlati munka eredményességéhez is

Career Indecision from the Perspective of Time Orientation

The present study focuses on the link between career indecision status and time perspective of high school students. Previous works mainly investigated the relationship between future orientation and career indecision, neglecting attitudes towards other time perspective dimensions, such as the past and the present. Therefore, our aim was to overcome this hiatus by using the Zimbardo Time Perspective Inventory (Zimbardo & Boyd, 1999) and Career Factor Inventory (Chartrand, Robbins, Morrill & Boggs, 1990) in a sample of 683 high school students. By considering variable-centered and person-centered analyses, results suggest that scores on TP factors are closely associated with the career indecision type that one can be classified into. “Path seeker” and “Ready to decide” students have a balanced time perspective; “Chronically indecisive” youngsters have a time perspective pattern which is dominated by the past negative factor and they are less future-oriented; “Choice anxious” students have scores lower on all TP factors (except Past-Negative TP) than any other group

“Branded, biased and it wants to sell a product”: typical ad representations influence the effect of ad recognition: a mixed-method research

In the present two-study mixed-method research, we aimed to explore how different ad representation dimensions influence the recognition of new advertising formats. Furthermore, we also investigated the effect of ad recognition on ad and brand liking. In line with the past applications of schema theory to advertising (Evans and Park 2015), as well as categorization theories, we found in both studies that ad representation dimensions influence ad recognition of new advertising formats, especially when the relevant feature is present in the ad. Ad representation dimensions such as branded, biased or selling facilitated ad recognition, while informative had a negative effect on ad recognition. The sponsored journal article represented an exception as both branded and biased representations hindered ad recognition. Furthermore, the effect of ad recognition on ad and brand liking varied across the tested messages. Theoretical and practical implications have been formulated. Future research might consider to further explore the effect of ad schemas on advertising and brand attitudes
