Individual Differences in the Impostor Phenomenon and its relevance in Higher Education
The impostor phenomenon is often viewed as a dysfunctional personality style with important implications for university students. An earlier investigation made by Leonhardt et al. (2017) has shown that different types of impostors can be distinguished based on their underlying characteristics. However, no study examined the association between Perfectionistic Self-presentation and the Dark Triad and its relation to this existing typology. We employed Latent class analysis (LCA) to investigate if different impostors can be distinguished based on the levels of IP, Perfectionistic self-presentation and Dark Triad (e.g., narcissism, machiavellianism, psychopathy). This analysis was further used to explore if some impostors are more prone to encounter academic-related difficulties (e.g., burnout, anxiety, and fear of failure) compared to others

The effect of husbandry system information on consumer willingness to pay for dairy products from cow-calf-contact systems
In modern dairy farming, separating the mother cow from the calf shortly after birth is common. This practice seems inevitable from a production economic perspective, but the dairy sector is subject to public concerns about whether this cow-calf separation meets sufficient levels of animal welfare.
Previous studies explored consumer attitudes towards common practices in conventional dairy husbandry but consumer willingness to pay (WTP) for avoiding contentious practices has not been established. We investigate the effectiveness of different information strategies on WTP for dairy products from cow-calf-contact systems, which avoid the common practice of separating the calve from its mother shortly after birth
Impact of Weight Development Because of Corona among Indonesian Adolescents
Obesity cases in Asia, including Indonesia currently have increased. In Indonesia, obesity or overweight is more prevalent in high Socio-Economic Position (SEP) groups and often tend to be perceived as a sign of affluence in a family (Rachmi et al., 2017; Roemling & Qaim, 2012). Many studies about obesity in Indonesia were among adults (i.e. Rachmi et al., 2017; Nurwanti et al., 2018). Little was known in Indonesia about obesity status among children and adolescents. Adolescence itself is a particularly vulnerable period for the development of overweight (Tsiros, 2008). Any changes in this period, most probably will affect in the next period. As such, it is important to understand weight development (and weight increases) during adolescence, particularly among adolescents from higher SEP.
In 2020, all of the world experienced hard covid pandemic and pressured most of the people to stay at home. Because of the restriction to stay at home, people got many health consequences (i.e. weight increasing). Weight increases are generally the consequence of the balance between the ‘Big two (i.e., energy expenditure versus intake). Many studies showed that people gain weight during COVID-19 lockdown (Rundle et al., 2020; Dun et al., 2021; Seok et al., 2021). This could be explained by the restrictions and the time available at home, having more possibilities for eating snack or junk food or calorie dense food (Poelman et al., 2021; Guzek et al., 2021). However, previous studies have been limited by cross-sectional designs. Some longitudinal studies supported weight increases over time, but these studies have been mostly performed among adult populations (e.g. Dicken et al., 2021). Less is known about weight changes among adolescent populations, particularly those from developing countries, such as Indonesia.
In Indonesia, the first COVID 19 case was confirmed in March 2020 and emergency response status was implemented with Pembatasan Sosial Berskala Besar (PSBB) or lock down from March to August 2020 (first lock down). Indonesia enforced a mandatory cordon sanitaire to curb the chain of COVID 19 transmission. Communities in all regions of Indonesia were encouraged to limit their mobility. (PP No. 21 of 2020). Schools were also closed from March 2020. There was a period after first lock down, that Indonesia began to have a new normal live and entertainments were opened again. However, schools still stayed close during these times. The new beta variants of COVID 19 arrived in Indonesia in June 2021 and caused many death cases (the highest peak of cases). From June until October 2021, Indonesia was in the peak lock down (second lock down) and the rules were even stricter than before (i.e., group activities were not available even for outside, limited people in the supermarket or public market). Such lockdown restrictions are likely to have wide-ranging consequences for public health, as they invariably change movement, work, social and leisure time activities ((Robinson et al., 2020)). As such, our longitudinal study compared the situation before COVID19 lockdown (autumn 2019) and during the second COVID 19 lockdown (autumn 2021) with respect to zBMI changes among adolescents from higher SEP.
Moreover, understanding who is more or less vulnerable to weigh gain during the pandemic is critical to further target public health interventions. Our previous cross-sectional study before COVID-19 found that boys from urban areas had the highest overweight prevalence (Sarintohe et al., 2022). Previous studies have similarly reported about gender and urban/rural areas as potential predictors of zBMI among children and adolescents in Indonesia (Nurwanti et al, 2019; Rachmi et al., 2017). Some previous studies explained that people with overweight and obesity status before pandemic have more chance to gain weight during COVID 19 compared to people that have normal weight or less (Poelman et al., 2021; Maltoni et al., 2021; Khan et al., 2022). The current longitudinal study will examine whether boys from urban areas are also the ones gaining most zBMI during COVID-19. We also will examine whether adolescents with higher z-BMI or have overweight or obesity status before pandemic will gain weight during COVID-19.
During COVID 19, people tend to consume comfort food, such as snacks andfast food, in order to decrease anxiety and stress symptoms, also boredom from the lockdown (Guzek et al., 2021; Pujia et al., 2021). One of the determinants of food preferences or choices are appetitive traits (Carnell et al., 2013). Appetitive traits are defined as persistent predispositions toward food (Guzek et al., 2020). They include food approach traits (such as, food responsiveness, emotional overeating). Food responsiveness is the urge to eat when you see, smell or taste palatable food and emotional overeating is the practice of consuming large quantities of food -- usually "comfort" or junk foods -- in response to feelings instead of hunger. Some studies during the lockdown have shown individual appetitive traits may explain overweight and increases in zBMI (Guzek et al., 2021; Sadler, 2021; Phillipe et al., 2021). The previous study was cross sectional and among adults. It is important to examine weight increases with longitudinal study. As adolescents were important phase, we will examine whether these appetitive traits will also explain zBMI development during COVID-19 among adolescents, also in combination with previously mentioned demographic variables (i.e., boys * food responsiveness). As boys from urban areas had the highest weights, they might also be the ones that are most vulnerable for weight increases during COVID-19, but probably only when they exhibit certain appetitive traits that make them vulnerable for consuming energy-dense (snack) foods during COVID-19 times. We also assumed that adolescents with higher zBMI before COVID 19 might also more vulnerable for weight increase during COVID 19, particularly when it combine with higher appetitive traits.
Taking into account the COVID 19 lock down, it must be noted that the present global situation may change some of weight status. Therefore, it is important to examine whether COVID 19 may have affected weight status among adolescents and factors that were correlated (i.e., demographic factors, appetitive traits). We performed a longitudinal study, to establish the order of association between demographic factors (sex and school area), emotional overeating and food responsiveness, and follow up z-BMI while controlling for baseline overweight status (z-BMI). We will either examine the combination between sex and emotional overeating or food responsiveness as moderator of the relation between z-BMI before and during the lockdown of COVID 19
Costly Boasting? The Effects of Self-Promotion on Cooperation
In general, self-promotion is considered socially unlikable. People perceive self-promoters as socially insensitive and less likable and therefore monitor themselves carefully to avoid being perceived as ‘braggart’ and risk social exclusion. Nevertheless, although self-promotion appears to be socially costly, other findings reveal a two-folded picture. This suggests that self-promoters may gain benefits in particular circumstances. In the present work, we review findings to common norms in self-presentation and the effect of self-promotion. In a proposed investigation, we aim to test how self-promotion affects interpersonal cooperation under distinct conditions. This involves two proposed studies, where participants evaluate individual profiles as coalition partners for a joint task. We expect self-promoters to be rated less preferential under favorable conditions. However, we expect this effect to flip under uncertain and high risk conditions. From the expected results we assume that unfavorable circumstances promote self-promoters in their perceived qualities as coalition partners

Continuing Health Education as a strategy to address the pandemic of COVID-19: A Scoping Review
To analyze the actions of permanent health education conducted at a distance for the qualification of professionals in response to the pandemic of COVID-19
Paying to Take
This project uses a modified dictator game to analyze the crowding-out effect within subjects.
Participants play multiple rounds of the dictator game with different endowments. In one block, the participants play the regular game. In another block of rounds, the participant faces a small monetary punishment to take money.
There are two monetary punishments, a fine and a fee. The fine reduces the outcome after the behavior. The fee has to be paid before the behavior.
The project further analysis the norms, beliefs, and "entitlement" associated with the behavior to further identify the mechanism behind any behavior change
Rhetorical Effectiveness of Insinuations - Experiment 2 (Perceived persuasiveness)
The ad hominem fallacy (henceforth, AH) "occurs when one party in a discussion criticises or attempts to refute the other party's argument by directly attacking that second party personally" (Walton, 1998, p. 2). This definition of AH is close to Bell (1997)'s definition of innuendoes (and, by extension, insinuations) with the difference that the latter is a negative ascription that must be implicitly conveyed without necessarily being part of an argumentative structure.
In line with the literature on the subject, the implicitness of insinuations offers many rhetorical advantages over asserted personal attacks: (i) as the attack is not explicitly stated, it must be inferred by the hearers, and the insinuators can deny that interpretation, (ii) the implicitness of a personal attack may allow the speaker to be perceived as less malevolent or dishonest, and (iii) since implicit meaning is less likely to be critically questioned than explicit meaning, a fallacious argument implicitly conveyed is less likely to be spotted.
This experiment is the second in the series of experiments investigating this difference in rhetorical effectiveness between asserted and insinuated AH. These experiments will consist of dialogues between two characters: the first one presenting a fact, a value or a policy proposal, and the second one answering that he or she is wrong by justifying his or her disagreement either by an asserted (i.e., explicit) AH, its insinuated (i.e., implicit) counterpart, or a neutral argument without personal attack.
This second experiment will investigate how persuasive participants find the second character's statement (as a whole, claim and argument, without any particular distinction), whether this statement is an assertive attack, an insinuated attack or a neutral (i.e., free of personal attack) argument. In contrast to the first experiment, the question of the statement's persuasiveness is not specific to one or other of the rhetorical facets (i.e., ethos [perceived image of the speaker], logos [composition of the speech], and pathos [emotion induced to the audience]) but rather a combined effect of them
