Balanced difficulty task finder: an adaptive recommendation method for learning tasks based on the concept of state of flow

2020

An adaptive task difficulty assignment method which we reckon as balanced difficulty task finder (BDTF) is proposed in this paper. The aim is to recommend tasks to a learner using a trade-off between skills of the learner and difficulty of the tasks such that the learner experiences a state of flow during the learning. Flow is a mental state that psychologists refer to when someone is completely immersed in an activity. Flow state is a multidisciplinary field of research and has been studied not only in psychology, but also neuroscience, education, sport, and games. The idea behind this paper is to try to achieve a flow state in a similar way as Elo’s chess skill rating (Glickman in Am Ches…

Anxiety in Older Adolescents at the Time of COVID-19

2020

Corona Virus Disease-19 (COVID-19) is a catastrophic health risk, with psychological, emotional, social, and relational implications. From the early stages of the virus spread, the elderly population was identified as the most vulnerable, and health authorities have rightly focused on this frailer population. Conversely, less attention was given to the emotional and psychological dimensions of children and adolescents. Moreover, even though they were the subjects whose lives and health were at low risk, they, nevertheless, had to face a reality full of anxiety, fears, and uncertainties. The current study investigated the state of anxiety and emotional awareness in a sample of healthy older …

Prediction of user action in moving-target selection tasks

2015

Selection of moving targets is a common, yet complex task in human–computer interaction (HCI), and more specifically in virtual reality (VR). Action prediction has proven to be the most comprehensive enhancement to address moving-target selection challenges. Current predictive techniques, however, heavily rely on continuous tracking of user actions, without considering the possibility that target-reaching actions may have a dominant pre-programmed component—this theory is known as the pre-programmed control theory.Thus, based on the pre-programmed control theory, this research explores the possibility of predicting moving-target selection prior to action execution. Specifically, three level…

L'adozione nel contesto e co-testo scuola. Literature review su adozione-scuola con Atlas.ti

Our research wants to be a meta-analysis work; its purpose is to focus on adoption and to analyse the “textual-semantic correlates” through which this topic has been understood and interpreted by international literature. In particular, the aim is to describe and codify the semantic-linguistic treatment of “adoption of children” theme with reference to school adjustment issue. In the title of the following thesis, “Adoption in the school context and co-text”, the term co-text (stemming from linguistics) points out the inquiry function in texts and the purpose of meta-reflective comparison among texts of articles coming from the journals with a high impact factor. After selecting those journ…

Trudności w szkolnej adaptacji dzieci sześcioletnich

2016

Jedną z istotniejszych idei ostatniej reformy edukacji w Polsce było obniżenie wieku obowiązku szkolnego z siedmiu do sześciu lat. We wrześniu 2015 roku wszystkie dzieci sześcioletnie rozpoczęły naukę w klasie pierwszej. Objęcie dzieci sześcioletnich obowiązkiem szkolnym wzbudziło wiele kontrowersji i liczne protesty społeczne, których efektem jest dzisiaj zapowiedź cofnięcia reformy. Celem opracowania jest próba oceny obecnej sytuacji - przedstawienie argumentów za i przeciw rozpoczęciu szkolnej edukacji dzieci sześcioletnich. Autorka zamieszcza także uwagi skierowane do najbliższego otoczenia dziecka - rodziców i nauczycieli, które mogą złagodzić trudy związane ze szkolną adaptacją.

Considerations regarding the alleged association between Herbalife products and cases of hepatotoxicity: a rebuttal.

2014

We thank Dr. K Appelhans et al. for their comments [1] on our paper [2], published online first in April 2012. In our review, we aimed to draw the attention of physicians to the uncontrolled and increasingly alarming use of herbal products and dietary supplements in the general population. In fact, in Italy this phenomenon, though still limited, has rapidly increased over the last few years. Here, use of herbal medicine products has increased to 3.7 %, while in other countries consumption is higher, reaching 20 % in the UK, and 40 % in the USA. Young non-smoking women with a high level of education appear to be the most common consumers [3]. It seems that women use these products more than …

The Mediating Role of C-Reactive Protein and Handgrip Strength Between Obesity and Walking Limitation

2008

OBJECTIVES: To study the association between different obesity indicators and walking limitation and to examine the role of C-reactive protein (CRP) and handgrip strength in that association. DESIGN: A cross-sectional, population-based study. SETTING: The Health 2000 Survey with a representative sample of the Finnish population. PARTICIPANTS: Subjects aged 55 and older with complete data on body composition, CRP, handgrip strength, and walking limitation (N=2,208). MEASUREMENTS: Body composition, anthropometrics, CRP, medical conditions, handgrip strength, and maximal walking speed were measured in the health examination. Walking limitation was defined as maximal walking speed less than 1.2…

The precursors of double dissociation between reading and spelling in a transparent orthography.

2016

Research and clinical practitioners have mixed views whether reading and spelling difficulties should be combined or seen as separate. This study examined the following: (a) if double dissociation between reading and spelling can be identified in a transparent orthography (Finnish) and (b) the cognitive and noncognitive precursors of this phenomenon. Finnish-speaking children (n = 1963) were assessed on reading fluency and spelling in grades 1, 2, 3, and 4. Dissociation groups in reading and spelling were formed based on stable difficulties in grades 1–4. The groups were compared in kindergarten phonological awareness, rapid automatized naming, letter knowledge, home literacy environment, a…
