Task-based language teaching (TBLT), an instructional approach for promoting real world communicative language use, has gained substantial attention among researchers and educators of additional languages, traditionally referred to as second languages (L2) and foreign languages (FL). Existing research on TBLT and tasks, predominantly conducted with adult learners, has primarily examined how meaning-focused tasks enhance (or do not enhance) learners’ communicative abilities in the target language and how different task implementations yield different outcomes (Ellis, 2017).

Clinical toxoplasmosis is a rare but often fatal disease that impacts several medical fields, including obstetrics, ophthalmology, transplantation, oncology and the context of the AIDS pandemic. The prognosis for patients with toxoplasmosis largely depends on timely treatment, which makes early diagnosis a priority for clinicians. However, diagnosing toxoplasmosis is a significant challenge due to the lack of specific clinical symptoms. This issue is further complicated by the high seroprevalence of Toxoplasma in the general population, which is far higher than the incidence of the disease. There are currently no clinically useful predictors for toxoplasmosis. Epidemiological studies and host–parasite interactions suggest that the incidence of toxoplasmosis depends on a combination of host and parasite factors. Significant risk factors include immunodeficiency, in utero exposure, genetic predisposition, anti-Toxoplasma antibody levels, older age, virulence of the strain, parasite burden and the infectious form of the parasite. Understanding these risk factors is important for clarifying the uncertainties regarding the incidence of toxoplasmosis and improving patient outcomes. In this review, we discuss the significance of these factors and current measurements for parasite-related factors. Additionally, we discuss potential preventive strategies that focus on screening as well as control of modifiable risk factors.

Oxidative stress is an important pathomechanism in psoriasis, and the oxidative balance score (OBS) serves as a standardised metric for assessing systemic oxidative status, but its association with psoriasis is unclear. This study included 18 023 adults from the National Health and Nutrition Examination Survey to investigate the relationship between OBS and psoriasis. After using a complex sampling weighting method, we performed multi-model logistic regression and stratified analysis with OBS as the exposure and psoriasis as the outcome for the primary analysis. Restricted cubic spline (RCS) plots were used to evaluate potential non-linear associations between OBS and psoriasis. In addition, we performed replication analyses using two 24-h dietary records data as a sensitivity test to ensure robustness of the results. Multi-model logistic regression analyses revealed no statistically meaningful link between OBS and psoriasis prevalence when accounting for all confounders (P > 0·05), but in stratified analyses, OBS demonstrated a significant association with reduced risk of psoriasis in individuals aged 60–80 years (OR = 0·27–0·35, P < 0·05). As part of the overall OBS, moderate dietary OBS demonstrated an association with reduced psoriasis risk in 60- to 80-year-olds (OR = 0·39–0·43, P < 0·05). Lifestyle OBS (LOBS) indicates a significant negative correlation with psoriasis risk among the ‘Other Hispanic’ group. (Q3 OR = 0·23, P < 0·05). The RCS showed a non-linear relationship between LOBS and psoriasis (non-linear P = 0·013). This study provides the first systematic confirmation of an association between OBS and a reduced risk of psoriasis in elderly populations and specific ethnic groups. These findings offer new insights and directions for the prevention and treatment of psoriasis.

Prominent theories claim that young Europeans are increasingly socialist as well as divided from their elders on non‐economic issues. This paper asks whether age‐based polarisation is really growing in Europe, using new estimates of the ideological positions of different age groups in 27 European countries across four issue domains from 1981 to 2018. The young in Europe turn out to be relatively libertarian: more socially liberal than the old in most countries but also more opposed to taxation and government spending. These age divides are not growing either: today's differences over social issues and immigration are similar in size to the 1980s, and if anything are starting to fall. Analysis of birth cohorts points to persistent cohort effects and period effects as the explanation for these patterns; there is little evidence that European cohorts become uniformly more right‐wing or left‐wing with age. Hence age‐based polarisation need not be a permanent or natural feature of European politics but is dependent on the changing social, political and economic climate.

This research analyzes how gender equality influences the participation of European senior citizens in a range of volunteering activities (Social Awareness, Professional and Political, Education, and Religion). The main contribution is the simultaneous consideration of different levels of data aggregation: individual, national and welfare system. This allows conclusions to be drawn on the effects of variables linked to sociodemographic characteristics, gender equality and welfare systems. The empirical estimation utilised microdata from the World Values Survey (2005/09 and 2010/14) and the United Nations Development Programme. Results suggest that the European senior citizens appear to believe that they are more equal than the official statistics of their countries indicate. Men are more likely to participate in professional and education activities; women are more likely to be involved in religious organisations. Welfare systems influence volunteering behaviours. The promotion of macro-policies for gender equality could be important for increasing participation in non-profit organisations.

The breach of psychological contract is the perception by the members of an organization that it has reneged on promises made when they began their relationship with it. This perception generates intense negative emotions and is an effective predictor of future behavior in the work setting. In this investigation, we explore the relations between breach of contract and organizational citizenship behaviors (OCBs) in volunteers. We also explore the mediator role of negative affect in the relationship between breach and citizenship behaviors and the moderator role of age. This study was carried out using a two-wave design, with 419 socio-assistential volunteers. The results support a direct effect of breach of contract on OCB and an indirect effect of breach through negative affect. Moreover, age moderates the relation between breach of psychological contract and negative affect. Lastly, the conditional effect of breach of contract on negative affect is greater in younger volunteers but loses its power in older volunteers. The implications are discussed in order to comprehend volunteers’ activity and design interventions.

The internet plays an important part in our daily lives. In this paper, we ask whether internet use is negatively related to civic life when focusing specifically on formal volunteering. Furthermore, we account for group-specific and activity-specific internet effects. Using a representative population sample of Switzerland, we show that internet use decreases the probability of undertaking voluntary work. This result is qualified in two respects: First, we find that the negative relationship between internet use and volunteering is more powerful among young people than older adults who are more likely to volunteer when they use the internet. Second, the use of social networking sites seems to mitigate the negative influence of internet use on volunteering.

This article examines the unexpected defeat of the Child Labor Amendment (CLA) by focusing on gender’s central role in the arguments of both its proponents and opponents. In foregrounding the plight of teenage girls toiling in factories, those supporting the CLA capitalized on widespread concerns with protecting future mothers. Meanwhile, opponents focused on the allegedly disempowered teenage boy, who would supposedly lose his right to work and become a “self-made man.” Arguments about gender regularly intersected with those around childhood, age, and race. This article augments the existing literature on the CLA’s downfall, which largely points to the post-World War I Red Scare as a primary culprit. By analyzing the rhetoric of both sides through the lens of gender, it becomes evident that even arguments about governmental overreach were often framed through gendered images, myths, and stories. Moreover, by analyzing state-level child labor laws rather than focusing only on the more prominent federal ones, we gain additional insight into how labor regulations in this era aimed to delineate distinct roles for boys and girls in the workplace—and outside of it.

Age has long been understood as a strong demographic determinant of volunteering. However, to date, limited literature exists on the episodic volunteer experience of different age groups, the impact of such episodic volunteer experiences, and why some individuals are motivated to volunteer episodically. Given this scarcity of research on age and episodic volunteering, the paper presents research examining age and episodic volunteering. Specifically, we studied age differences in three different aspects of episodic volunteering: the motivation to volunteer at a one-time event; the volunteer experience; and the volunteer post-event evaluation. In each of these aspects, we examined similarities and differences among six different age groups in a population of 2270 episodic volunteers from six countries. The research contributes to a better understanding of the significance of age in episodic volunteering, the ways in which people perform episodic volunteering at different ages, and the impact of these volunteer activities.

Age is often found to be associated with a plenitude of socioeconomic, politico-administrative, biological and thanatological variables. Much less attention has been paid by scholars, however, to explaining ‘age’. In this paper we address this unfortunate scientific lacuna by developing a model of ‘age’ as a function of several factors suggested by (post)rational choice and social constructionist theories. Using state-of-the-art multilevel statistical techniques, our analysis allows the determinants of age to vary with the institutional characteristics of European countries. Our findings convincingly show that generalized trust in strangers, support for incumbent extremist political parties in provincial elections held in the month of January, and the percentage of overqualified women in the cafeterias of national parliaments are all statistically significant explanations of ‘age’. Our findings have obvious implications for conspiracy theorists, organizational advisors, spin doctors and ordinary charlatans.

While intersectionality is a recurrent theme in the literature on women's political representation, few studies empirically disentangle who are the women who get elected to parliaments. An argument on biases in recruitment practices suggests that those who are members of more than one outgroup, such as young women, benefit from an ‘outgroup advantage’. In elections, a candidate with two outgroup features might attract more voter support than a candidate with just one outgroup feature. Hence, nominating a candidate that is both young and female could be a rational move by (male) elites in political parties that allows them to open fewer seats to newcomers. These expectations are tested on data for all members of the European Parliament since 1979. Not only is it found that women's presence increased steadily throughout the parliament's history, but also that women's representation is consistently highest among the group of young representatives, lower among middle‐aged Members of the European Parliament and lowest among older representatives.

This study examines the elicited production of Spanish infinitives versus gerunds among Spanish/English bilingual children and adolescents in the United States. We focus on three contexts: infinitives in subject position, infinitives with the phrasal verb parar de (“to stop doing something”), and infinitives with the prepositional verb parar a (“to stop to do something”). Results showed that children and adolescents produced fewer infinitives than their Spanish-dominant parents in subject position and with parar de, often overextending the gerund. By contrast, all groups performed more accurately with parar a, where English and Spanish align structurally. Language dominance and Spanish experience significantly predicted more target-like infinitive use, while chronological age and English dominance were associated with increased gerund overextension. These findings support the Bilingual Alignment Hypothesis, showing that heritage Spanish morphosyntactic development is gradual and context-sensitive, with greater accuracy in areas of crosslinguistic convergence.

In this study, we investigate the impact of the age of prime ministers and ministers on the stability of governments across 21 democracies. We examine this issue by using Cox survival analysis, leveraging an original dataset and adopting a comparative perspective. The findings of the study document that younger prime ministers face a lower risk of government discretionary termination compared to their older counterparts. This effect does not appear to be statistically significant for cabinet ministers. By shedding light on this uncharted relationship, we contribute to the flourishing literature on youth representation in politics and the established research agenda on the factors affecting the survival in office of democratic governments. We conclude the study by discussing the implications of the findings for democracy and suggesting avenues for future research.

Efficient coordination is a major source of efficiency gains. We study in an experimental coordination game with 727 children and teenagers, aged 9 to 18 years, the strategies played in pre-adulthood. In our one-shot, experimental coordination game, we vary the incentives for reaching the more efficient equilibrium and the number of subjects within a group. Looking at strategy choices dependent on age, we do not find robust age effects in the aggregate. Yet, we see that smaller group sizes and larger incentives increase the likelihood of choosing the efficient strategy. The larger strategic uncertainty in larger groups is obviously harmful for overall efficiency. Regarding incentives, we find that increasing the profits in the efficient equilibrium seems to work better than providing a cushion in case of miscoordination. Beliefs play an important role as well, as subjects are more likely to play the efficient strategy when they expect others to do so as well. Our results are robust to controlling for individual risk-, time-, and social preferences.
