Precise vs General Feedback in Reducing Field-Dependence
1980
Summary.-To investigate the effect of feedback on performance of the Rod-and-frame Test the standard test procedure mas altered. The result of the alteration was a procedure which was called the Rod-and-frame Test as a Learning Task. On this task the subiect has to adjust the rod to the vertical twice in succession from each tilting position, whereby he is permitred a maximum of 10 trials in each tilting position and a range of tolerance of elo. After each trial the subject is given feedback about his performance. An experiment was conducted with 30 male and 30 female students to investigate whether a precise feedback giving both the direction and the degree of the rod's deviation from the …
Emotional intelligence intervention in older adults to improve adaptation and reduce negative mood.
2020
AbstractObjectives:Emotional intelligence (EI) is a strong predictor of negative mood. Applying emotional skills correctly can help to increase positive emotional states and reduce negative ones. This study aims to implement EI intervention designed to improve clarity, repair EI dimensions and coping strategies, and reduce negative mood in older adults.Design:Participants were randomly assigned to the treatment or control group.Setting:Participants were evaluated individually before and after the intervention.Participants:Participants included 111 healthy older adults; 51 in the treatment group and 60 in the control group.Intervention:An EI program was implemented. The program was administe…
The Effects of Mindfulness and Self-Compassion on Improving the Capacity to Adapt to Stress Situations in Elderly People Living in the Community
2015
ABSTRACTObjectives: This study aimed to show the effectiveness of mindfulness and self-compassion therapy in improving coping ability and adaptation to stressful situations in the elderly.Methods: Forty-five elderly non-institutionalized adults were randomized to either treatment or a treatment waiting list. A pre- and post-treatment assessment was performed, consisting of the Brief Resilient Coping Scale (BRCS), Depression Anxiety Stress Scales (DASS), and Coping Strategies Questionnaire. The program was developed over 10 sessions lasting 120 minutes each.Results: Analysis of variance for repeated measures showed significant differences in the time-group interaction for the treatment’s eff…
Echo cancellation system for iso-frequency repeaters : contribution to the development of a new generation digital repeater
2014
On-frequency repeaters are a cost-effective solution to extend coverage and enhance wireless communications, especially in shadow areas. However, coupling between the receiving antenna and the transmitting antenna, called radio frequency echo, increases modulation errors and creates oscillations in the system when the echo power is high. According to the communication standards, extremely weak echoes decrease the transmission rate, while strong echoes damage electroni ccircuits because of power peaks. This thesis aims at characterizing the echo phenomenon under different modulations, and proposing an optimized solution directly integrated to industry. We have turned to digital solutions esp…
ASSESSMENT OF THE IMPACT OF VERMICOMPOST AND PEAT EXTRACTS ON NUTRIENT ACCUMULATION IN TUBERS AND POTATO YIELD
2018
Investigations on the potential beneficial effect of humic substances on crop plant cultivation under extremely diverse soil and climatic conditions is of global character, thereby knowledge obtained on the basis of local investigations are of great importance world-wide. The aim of the research was to evaluate the effect of different application methods (seed tuber treatment and foliar application) of commercially-produced peat and vermicompost extracts on nutrient uptake in tubers and yield of potato ( Solanum tuberosum L.) using field experiments in organic farming system with potato variety ‘Borodjanskij Rozovij’. The tested extracts from the organic products included: peat extract (K45…
Repeatability and reliability of the diabetic foot self-care questionnaire in Arabic patients: A transcultural adaptation.
2022
Abstract Purpose The diabetic foot self-care questionnaire is considered a self-care evaluation tool with 16 questions for assessing diabetic foot health disorders. To date, the DFSQ has been validated in different languages, but an Arabic version was lacking. Consequently, the purpose of this study was to translate and validate the Arabic version of the DFSQ (DFSQ-AR). Method A suitable method was developed for the translation protocol and cross-cultural validation from Spanish to Arabic. Regarding the total marks from each sub-scale, agreement degrees and confidence were analyzed using Cronbach's α and intraclass correlation coefficient (ICC), respectively. In addition, the mean ± standar…
STR analysis of artificially degraded DNA--results of a collaborative European exercise.
2003
Degradation of human DNA extracted from forensic stains is, in most cases, the result of a natural process due to the exposure of the stain samples to the environment. Experiences with degraded DNA from casework samples show that every sample may exhibit different properties in this respect, and that it is difficult to systematically assess the performance of routinely used typing systems for the analysis of degraded DNA samples. Using a batch of artificially degraded DNA with an average fragment size of approx. 200 bp a collaborative exercise was carried out among 38 forensic laboratories from 17 European countries. The results were assessed according to correct allele detection, peak heig…
Alterations of DNA Repair in Melanoma Cell Lines Resistant to Cisplatin, Fotemustine, or Etoposide
2000
Resistance to chemotherapy is a common phenomenon in malignant melanoma. In order to assess the role of altered DNA repair in chemoresistant melanoma, we investigated different DNA repair pathways in one parental human melanoma line (MeWo) and in sublines of MeWo selected in vitro for drug resistance against four commonly used drugs (cisplatin, fotemustine, etoposide, and vindesine). Host cell reactivation assays with the plasmid pRSVcat were used to assess processing of different DNA lesions. With ultraviolet-irradiated plasmids, no significant differences were found, indicating a normal (nucleotide excision) repair of DNA photoproducts. With singlet oxygen-treated plasmid, the fotemustine…
The molecular characterization of a depurinated trial DNA sample can be a model to understand the reliability of the results in forensic genetics
2014
The role of DNA damage in PCR processivity/fidelity is a relevant topic in molecular investigation of aged/forensic samples. In order to reproduce one of the most common lesions occurring in postmortem tissues, a new protocol based on aqueous hydrolysis of the DNA was developed in vitro. Twenty-five forensic laboratories were then provided with 3.0 μg of a trial sample (TS) exhibiting, in mean, the loss of 1 base of 20, and a molecular weight below 300 bp. Each participating laboratory could freely choose any combination of methods, leading to the quantification and to the definition of the STR profile of the TS, through the documentation of each step of the analytical approaches selected. …
Effect of intensive exercise in early adult life on telomere length in later life in men
2015
A career as an elite-class male athlete seems to improve meta-bolic heath in later life and is also associated with longer life expectancy. Telomere length is a biomarker of biological cellu-lar ageing and could thus predict morbidity and mortality. The main aim of this study was to assess the association between vigorous elite-class physical activity during young adulthood on later life leukocyte telomere length (LTL). The study partici-pants consist of former male Finnish elite athletes (n = 392) and their age-matched controls (n = 207). Relative telomere length was determined from peripheral blood leukocytes by quantita-tive real-time polymerase chain reaction. Volume of leisure-time phy…
