Social representation of global climate change: an exploratory study focusing on emotion
No full textClimate change is a complex, emerging concept, and emotions seem to play a vital role in its social construction. We aimed to explore social representations of global climate change, especially from the perspective of emotions. We investigated emotions as representational components and, by applying anxiety, as psychological anchors affecting the organization and contents of representations. Free associations to the inductor “global climate change” were collected from 287 Hungarian respondents (Mage = 32.7, SD = 12.1 years). They were submitted to specificities, prototypical and similarity analyses (IRaMuTeQ software). Anxiety was measured with STAI, using the Trait subscale. Results show an integrated representation of natural and human-related aspects. Fear and anxiety were the most frequently mentioned emotions. Fear was a prominent concept, as part of the representation was organized around it. More anxious participants tended to anchor climate change as more ominous and unavoidable. Less anxious participants had a distanced view, while actions were central for participants with medium anxiety. We discuss how these results compare to previous findings and what might be the sources and implications of group differences, especially from a climate communication view

Sound and Fury: McCloskey and Significance Testing in Economics
No full textFor about twenty years, Deidre McCloskey has campaigned to convince the economics profession that it is hopelessly confused about statistical significance. She argues that many practices associated with significance testing are bad science and that most economists routinely employ these bad practices: “Though to a child they look like science, with all that really hard math, no science is being done in these and 96 percent of the best empirical economics. . .” (McCloskey 1999). McCloskey’s charges are analyzed and rejected. That statistical significance is not economic significance is a jejune and uncontroversial claim, and there is no convincing evidence that economists systematically mistake the two. Other elements of McCloskey’s analysis of statistical significance are shown to be ill-founded, and her criticisms of practices of economists are found to be based in inaccurate readings and tendentious interpretations of their work. Properly used, significance tests are a valuable tool for assessing signal strength, for assisting in model specification, and for determining causal structure.statistical significance, economic significance, significance testing, regression analysis, econometric methodology, Deirdre McCloskey, Neyman-Pearson testing

Iskolai demokrácia és részvételiség
No full textInternational literature shows that school practices are perceived by students as democratic. Also, based on the opinions and participation of students, these have many positive effects. Examples include higher engagement, cohesion, learning motivation, and improved academic performance. However, practical implementation is greatly hindered by the fact that, due to lack of time, financial constraints, and general overload, school workers often refrain from listening to students’ opinions and incorporating them into decision-making processes. This study examined the practice and impact of involving young people in participation processes among Hungarian adolescents. It was hypothesized that those who experience participation report higher collective efficiency and trust in decision-makers, just as community identification will be more typical among them compared to those young people who are not involved in other decision-making processes at school. Data were collected in 2023 (N=841). Using Jamovi statistical program version 2.3.28, and implementing the Mann-Whitney U test, differences between groups were examined and, in addition to our hypotheses being confirmed, the descriptive data showed that nearly 40-70% of the students felt that the students are not involved in situations of school life such as the establishment of house rules, disciplinary matters involving students and the settlement of teacher-student conflicts. Based on the responses of the participants, the most common form of participation is the involvement of student governments in making decisions about school event organization, which is in line with what is found in the literature.A nemzetközi szakirodalom azt mutatja, hogy a diákok által demokratikusnak érzékelt, a diákok véleményére és részvételére építő iskolai gyakorlatok számos pozitív hatással járnak. Ilyen például a magasabb elkötelezettség, kohézió, tanulási motiváció és a javuló akadémiai teljesítmény. Azonban a gyakorlati implementációt nagyban hátráltatja, hogy az iskolai dolgozók időhiány, anyagi korlátok és általános túlterheltség miatt sok esetben eltekintenek a diákok véleményének meghallgatásától és a döntéshozatali folyamatokba beépítésétől. Jelen tanulmány a fiatalok részvételi folyamatokba bevonásának gyakorlatát és hatását vizsgálta magyar serdülők körében. Feltételeztük, hogy a részvételiséget megtapasztalók magasabb kollektív hatékonyságról, döntéshozókkal kapcsolatos bizalomról számolnak be, és körükben jellemzőbb lesz a közösségi azonosulás azokhoz a fiatalokhoz képest, akiket nem vonnak be az iskola egyéb döntési folyamataiba. Az adatok felvételére 2023-ban került sor (N = 841). A Jamovi statisztikai program 2.3.28 verziójával, Mann–Whitney U-próba segítségével vizsgáltuk a csoportok közötti különbségeket, és amellett, hogy hipotéziseink megerősítést nyertek, a leíró adatok azt mutatták, hogy a diákok közel 40-70%-a úgy tapasztalja, hogy a diákokat nem vonják be az iskolai élet olyan helyzeteibe, mint a házirend kialakítása, a diákokat érintő fegyelmi ügyek és a tanár-diák konfliktusok rendezése. A résztvevők válaszai alapján a leggyakoribb részvételi forma a diákönkormányzatok bevonása az iskolai rendezvényszervezéssel kapcsolatos döntések meghozatalába, ami összhangban van a szakirodalomban találtakkal
Iskolai bántalmazás a diákok perspektívájából
No full textPeer harassment is common during the school years, and causes long-term difficulties for students on the periphery of the group and for the whole class. Systems approach puts the community in the focus of attention: bystander is treated as an active agent instead of a passive one, which has the power to reinforce or prevent power imbalances. The research has focused on examining students mentalization processes through their narratives. In present study the responses of a total of 138 ninth-graders from three Hungarian schools (Budapest, Martfű and Barcs) were analysed. Questionnaire package included Ken Rigby’s Bullying Prevalence Questionnaire and an instruction which allowed the collection of school bullying stories. Based on the results obtained, members of the class community attribute mental states to their peers to different degrees depending on the role they perceive themselves in the dynamics of bullying.A kortársak zaklatása gyakori jelenség az iskolai évek során, hosszú távú nehézségeket okozva a csoport perifériájára szorult diákok és az egész osztályközösség számára. A probléma rendszerszemléletű megközelítése a figyelem fókuszába helyezi az egész közösséget, a szemlélőket passzív helyett aktív ágensként kezeli, és a zaklató-áldozat hatalmi dinamikáját megerősítő vagy hátráltató erőként vizsgálja. Jelen kutatás a diákok mentalizációjának vizsgálatára fókuszált iskolai bántalmazásról szóló narratíváikon keresztül. Három magyarországi iskola (Budapest, Martfű és Barcs) összesen 138 kilencedikes diákjának válaszai kerültek elemzésre. Az eszközök között szerepelt Ken Rigby Iskolai Zaklatás Kérdőíve, illetve egy iskolai bántalmazásról szóló történet felidézését szolgáló instrukció. A kapott eredmények alapján elmondható, hogy az osztályközösség tagjai eltérő mértékben tulajdonítanak mentális állapotokat társaiknak attól függően, hogy milyen szerepben észlelik magukat a bullying dinamikájában
Encapsulation of an Organic Phase Change Material in Wheat Straw Derived Cellulose by Spray Drying
No full textPhase change materials (PCMs) have the potential to provide valuable thermal energy storage. However, PCMs are not widely used due to challenges with their implementation. Factors including leakage, high-cost materials, energy-intensive processes, and the presence of potentially toxic chemicals are barriers to the widespread use of PCMs. A promising approach is to use biomass derived materials for the encapsulation of PCMs, providing inexpensive and non-toxic wall materials. Spray drying processes are more favorable for large scale production than other encapsulation methods. Many studies have used cellulose or cellulose derivatives to encapsulate PCMs, however most of these methods pose significant challenges to scale up, either due to costs, toxicity, or difficulties with the method itself. This work aims to develop a process for the microencapsulation of a PCM using biomass derived wall materials and a spray drying process. This involved the isolation of cellulose from wheat straw, size reduction of cellulose, design and testing of a laboratory scale spray dryer, and spray drying of a cellulose stabilized PCM emulsion. It was found that cellulose could effectively be isolated from wheat straw, and several methods for size reduction were promising for encapsulation. In addition, two spray dryer prototypes were developed, which were able to successfully spray dry during testing, however they had low solids recovery. Successful microencapsulation of the PCM in cellulose by spray drying appears to have occurred based on SEM analysis. Further work is needed to improve cellulose size reduction, emulsion formation for encapsulation, spray dryer performance and operation, as well as rigorous evaluation of the produced microcapsules
