Young Children Are Wishful Thinkers: The Development of Wishful Thinking in 3- to 10-Year-Old Children

Previously, research on wishful thinking has found that desires bias older children’s and adults’ predictions during probabilistic reasoning tasks. In this article, we explore wishful thinking in children aged 3- to 10-years-old. Do young children learn to be wishful thinkers? Or do they begin with a wishful thinking bias that is gradually overturned during development? Across five experiments, we compare low- and middle-income United States and Peruvian 3- to 10-year-old children (N = 682). Children were asked to make predictions during games of chance. Across experiments, preschool-aged children from all backgrounds consistently displayed a strong wishful thinking bias. However, the bias declined with age.     

Recording the war effort: immigrant communities in Latin America and the memory of the Great War

ABSTRACT

This paper aims to analyse the initiatives undertaken by some immigrant communities residing in Latin America to record their mobilisation around the First World War. After the armistice, European communities in Argentina, Bolivia, Brazil, Chile, Mexico, Paraguay, Peru, Uruguay and other countries gathered detailed information about their activities during the conflict, published as profusely illustrated books of remembrance, offered to their governments as proof of their loyalty. The article intends to establish the peculiar nature of these publications as records of the war effort, and analyse the agents and processes of their elaboration, and their role as commemorative but also as archival documents.     

Limitations on the human capital transferability of adult migrants in Spain: Incentive or barrier for a new investment in education?

Many empirical studies on immigrant integration document the benefits of an education acquired in the country of destination. In this article; we study how the degree of human capital transferability affects an immigrant's chances of studying in Spain. We used data from the Spanish Labour Force Survey (2008–2015) for a sample of adults aged 18–55 who had left the educational system. The main findings show that natives are the ethnic group with the highest likelihood of re-enrolling in education. Amongst immigrants, those with fewer limitations on human capital transferability also invest more. These results question the predictions of the Immigrant Human Capital Investment model which expect that immigrants whose human capital depreciates upon arrival and those who can obtain a higher return on a new investment in education are therefore more likely to study. Moreover, the effect of skill transferability differs depending on the type of obstacle and the kind of education. Immigrants with less linguistic and cultural familiarity with the host country are less likely to undertake non-formal education than formal education. However, when the transferability obstacles are related to administrative requirements and legal restrictions, the probability of investing in non-formal education is higher. We conclude that immigrants with low skill transferability are not only less well integrated in the labour market upon arrival, but are also less able to redress that disadvantage through a new investment in education.     

Impact of Web 2.0 on national libraries

Web 2.0 has had an impact on library web sites making them more interactive with users, giving rise to the term Library 2.0. What is meant by Web 2.0 tools is generally understood but the degree of implementation of these tools in libraries is largely unknown. This study reports on the implementation of these tools in national libraries all over the world in order to give an objective measure of the impact of Web 2.0 on library web sites.     

A deep vein thrombosis caused by 20209C>T mutation in homozygosis of the prothrombin gene in a Caucasian patient

Introduction:

Additional nucleotide substitutions in the 3′-untranslated region of prothrombin gene could explain some thrombotic events and also adverse pregnancy outcomes. We describe the first case of a homozygous 20209C>T mutation as the cause of deep vein thrombosis in a Spanish patient.

Case and methods:

The 56-year-old male patient with a partial tear of the Achilles tendon developed calf (tibial) deep vein thrombosis after immobilization and was treated with an anticoagulant. To determine if the deep vein thrombosis was of genetic origin, a peripheral blood DNA sample was analysed for the presence of the three most frequent mutations associated with thrombotic events: factor V Leiden (1691G>A), prothrombin (20210G>A) and methylene tetrahydrofolate reductase (677C>T). The presence or absence of the normal allele of prothrombin could not be determined using the PTH-FV-MTHFR StripAssay (Vienna Lab).

Results:

Comprehensive analysis showed that the patient had a variant interfering with the polymerase chain reaction product, we sequenced the entire prothrombin gene and found that the patient had a homozygous C>T mutation at position 20209; this interfered with the polymerase chain reaction product, which needs a C at this position to be able to bind to the wild-type probe present in the test strip.

Conclusion:

The homozygous 20209C>T mutation and the presence of the mutation 677C>T in heterozygosity explained the patient’s deep vein thrombosis because the combination of mutations would increase the risk of thrombosis. Suitable genetic counselling should be provided to the patient and first-degree relatives as it important to detect prothrombin gene variants that could increase risk for thrombotic events.     

Hard Cash and Soft Skills: Experimental Evidence on Combining Scholarships and Mentoring in Argentina

Abstract

We evaluate a long-standing program run by one of the largest education foundations in Argentina that offers scholarships and nonacademic mentoring to secondary school students. We randomly assigned 408 grade 6 students within 10 public schools in the Province of Buenos Aires to either receive the program throughout secondary school or not to receive it. After three years, the program improved students’ academic behaviors (e.g., studying before an exam or catching up on missed work), but we find little evidence that these changes translated into broader improvements in students’ academic mindsets (e.g., self-beliefs about performance and efficacy), perseverance (e.g., grit), or learning strategies (e.g., metacognition). The program also improved students’ performance in school during the first year (e.g., grades, attendance, and passing rates), but we do not find similar gains in subsequent years. This may be due to a large share of treatment students being expelled from the program for not meeting its requirements. The program did not improve student learning or personality traits (e.g., conscientiousness). Finally, we find some heterogeneous effects for female students and students from low-income families.     

Teachers’ enactments of curriculum: Fidelity to Procedure versus Fidelity to Goal for scientific argumentation

Fidelity of implementation (FOI) has received attention in calls for funding and research; however, there are numerous ways of conceptualising and measuring this construct. We argue that this conceptualisation is important for recent reform efforts focused on science practices. Consequently, we explored FOI in the context of the enactment of a middle-school curriculum focused on one particular science practice, argumentation. We coded videos of five teachers’ enactments of argumentation lessons using two different fidelity coding schemes. First, Fidelity to Procedure targeted teachers’ adherence to the order and types of procedures. Second, Fidelity to Goal examined teachers’ adherence to the overarching argumentation goals. This analysis resulted in case studies that illustrate distinct patterns in the teachers’ curriculum enactments. One case in particular, Ms Newbury, received a low score for Fidelity to Procedure, but a high score for Fidelity to Goal. She altered procedures to provide her students, all of whom were English Language Learners, with different linguistic supports, but maintained the overarching argumentation goals. Consequently, we argue that FOI for goals may better capture whether teachers’ enactments are supporting students in the science practices. Furthermore, the results suggest the importance of educative curriculum including rationales for the curricular goals.
