Hebrew version of the Jansari assessment of Executive Functions for Children (JEF-C©): translation, adaptation and validation

The Jansari assessment of Executive Functions for Children (JEF-C©) is a non-immersive computerized assessment of executive functions (EFs). This study aimed to create a cross-culturally adapted Hebrew version, JEF-C(H)© and to assess reliability and validity in the Israeli context. Forty typically developing Israeli children and adolescents, aged 11–18 years, were assessed with JEF-C(H)©. In addition, participants and their parents filled in the Behaviour Rating Inventory of Executive Function (BRIEF). JEF-C(H)© was found to be feasible in Israeli children and adolescents. The internal consistency was acceptable (Cronbach’s alpha = 0.79). Most of the JEF-C(H)© subtests and the Average score showed significant positive moderate to high correlations with age, ranging from 0.40 to 0.78 demonstrating construct validity. Multiple significant correlations were also found between the JEF-C(H)© Average score and the BRIEF indices as well as total score in the Parent and Self-report questionnaires. These preliminary findings support the reliability and validity of this version. Current findings demonstrate the potential clinical utility of JEF-C(H)© as an ecologically valid tool for Israeli children and adolescents in the assessment of EFs

Investigating the impact of nicotine on executive functions using a novel virtual reality assessment

Aims Nicotine is known to enhance aspects of cognitive functioning in abstinent smokers but the effects on specific areas of executive functions, and in non-smokers are inconclusive. This may be due in part to the poor sensitivity of tests used to assess executive functions. This study used a new virtual reality assessment of executive functions known as JEF (the Jansari assessment of Executive Functions) to address this issue. Design 2x2 design manipulating group (smokers and never-smokers) and drug (nicotine [4mg for smokers; 2mg for never smokers] vs placebo gum). Setting School of Psychology; University of East LondonParticipants 72 participants (aged 18 to 54). 36 minimally-deprived (2 hr) smokers and 36 never-smokers.Measurements Components of executive function were measured using the virtual reality paradigm JEF, which assesses eight cognitive constructs simultaneously as well as providing an overall performance measure. Results Univariate ANOVAs revealed that nicotine improved overall JEF performance, time-based prospective memory and event-based prospective memory in smokers (p < 0.01) but not in never-smokers. Action-based prospective memory was enhanced in both groups (p < 0.01) and never-smokers out-performed smokers on selective thinking and adaptive thinking (p < 0.01). Conclusions. Overall executive functioning and prospective memory can be enhanced by nicotine gum in abstinent smokers. That smokers were only minimally deprived suggests that JEFis a sensitive measure of executive functioning and that prospective memory is particularly susceptible to disruption by abstinence

Editorial

The current volume starts a new journal. The Journal of Ethnology and Folkloristics (JEF) is a multidisciplinary forum for scholars. In the first place we aim to combine the efforts of Estonian anthropologists, ethnologists and folklorists. JEF will be published twice a year jointly by the Estonian Folklore Archives at the Estonian Literary Museum (EFA), the Estonian National Museum (ENM), the Department of Estonian and Comparative Folklore and the Department of Ethnology at the University of Tartu (UT). JEF is a successor to the journals Pro Ethnologia (19 volumes, published by the Estonian National Museum between 1993 and 2005) and Studies in Folk Culture (5 volumes, published by the Department of Estonian and Comparative Folklore and the Department of Ethnology at UT between 2003 and 2005)

Sequential trials and the English rule

The allocation of trial costs and the way a trial progresses are two important issues in civil procedure. The combination of these two elements has received relatively little attention in the law and economics literature. The prior literature has only compared unitary litigation (e.g. liability and damage issues are litigated, after which the court decides on both issues) under the American rule with sequential litigation (e.g. the parties first litigate the liability issue after which the court makes a decision, and then if still necessary the parties litigate the damages issue) under the American rule. In this article, I examine the influence of sequential litigation when the loser at trial pays all the litigation costs and compare the results with (a) the situation in which litigation is unitary and the loser pays all the litigation costs and (b) the situation in which litigation is sequential and each party bears her own costs. I focus on the incentive to sue, the incentive to settle (or to litigate) and on the settlement amount. Some interesting differences with the previous literature are discussed in detail

The UK Joint Expeditionary Force (JEF)

The JEF is a flexible and NATO compatible national British contingency force incorporating contributions from eight smaller allies and partners. It was conceived as part of the UK’s post-Iraq and post-Afghanistan strategic reset, to rebuild a contingency force and maintain relations with the smaller countries the British forces had operated in conjunction with.Initially focused mainly at operations outside Europe, the JEF has since 2014 also prepared for larger operations in the European theatre to re-assure allies and deter Russia
