Show moreIrrespective of discipline, the publication of null or non-significant findings is rare in the social sciences. For burgeoning fields like terrorism research, this is particularly problematic. As well as increasing the likelihood of Type II errors, the selective reporting of significant findings ultimately impedes progression, hindering comprehensive syntheses of evidence and enabling ill-supported lines of scientific enquiry to persist. This manuscript discusses several structural and individual-level variables which failed to produce significant, linear associations with involvement in terrorist violence in a dataset (N = 206) of right-wing and jihadist extremists active in Europe and North America. After considering methodological factors such as non-random distributions of missing data, we illustrate how certain variables are significantly associated with involvement in terrorist violence at particular periods in a radicalizing individual’s lifespan, but not others (i.e., pre- or post-radicalization onset). Moreover, we demonstrate that while some static, binary constructs (such as whether or not a radicalizing individual was exposed to diverse viewpoints) are not associated with terrorist violence, their influence over time produces different associations. We conclude that radicalization may be less about individuals having pre-disposing risk factors, such as biographical stressors, and more about cognitive changes that allow individuals to re-evaluate their lives through the lens of an extremist ideology. We also underline the importance of taking a temporal, rather than static, perspective to better understand the variables associated with the outcomes of radicalization trajectories. Show less

Show moreSelf-ageism has a significant negative impact on older people's ageing experiences and health outcomes. Despite ample evidence on cross-cultural ageism, studies have rarely looked into the way cultural contexts affect self-ageism. In this article, we compare expressions of self-ageism and its possible predictors across four European countries based on two questionnaires in a study sample of 2,494 individuals aged 55 and older. We explore how predictors of self-ageism are moderated by cultural values in a comparative fixed-effects regression model. We empirically show that similarly to ageism, self-ageism is not present in the same way and to the same extent in every country. Moreover, the level to which cultures value hierarchy and intellectual autonomy significantly moderates the association between self-ageism and individual predictors of self-ageism. Our study adds to the small existing body of work on self-ageism by confirming empirically that certain expressions of self-ageism and individual predictors are susceptible to change in different cultural contexts. Our research results suggest that self-ageism interventions may benefit from a culturally sensitive approach and imply that more culturally diverse comparisons of self-ageism are necessary to figure out fitting ways to reduce self-ageism.

Show moreIn recent years, a multitude of intergenerational contact programmes and interventions has emerged to counteract ageism among young adults. Research on these programmes and its supposed effect on ageism often start from the assumption that intergenerational contact follows a largely linear process in which a high level of encounters, in the right setting, decreases ageism and negative stereotyping. The purpose of this article is to critically examine this assumption by focussing on the underlying process of intergenerational contact, rather than examining the positive or negative outcome. Using in-depth interviews with 35 young adults, we found that although conditions and mediating factors during the contact do play a role in the outcome of intergroup contact, the process of contact is rather varied and does not follow a linear path. The results reveal that whether or not a positive contact experience translates into a changed group image of older people is related to the positioning of such experience within the young adults? personal frame of reference. We found that this has to do with the young adults having diverse and both positive and negative previous experiences, their grandparent-grandchild relationship, stories from others and personal characteristics. With this study, we point to the complexity of intergenerational contact and highlight potential pathways leading to varying group images of ?the old?. Show less

Show moreIn recent years, the use of primary data in terrorism research has increased. In order to maximise the benefits of this trend, we want to encourage terrorism scholars to implement open science practices more systematically. This article therefore presents different avenues towards open and reproducible terrorism studies. After introducing the open science movement and advantages of open science, we report an online survey study (N = 75) that shows that terrorism researchers have favourable attitudes towards and are keen to engage in open science activities. Findings, however, also point to key challenges that might prevent the implementation of open science in terrorism studies. Survey respondents were particularly concerned about sharing sensitive data, the risk of malicious practices, publishing in low-impact open access outlets, and indicated that open science seemed mainly targeted at quantitative research. To illustrate how researchers from different backgrounds and with potential resource restrictions can adopt open science practices, we propose practical solutions to address and reflect on these barriers.
