Preschool Aged Children

This study explores the relationship between word learning and conceptual organization for preschool-aged children. We proposed a bidirectional model in which increases in word learning lead to increases in taxonomic organization, which, in turn, leads to further increases in word learning. In order to examine this model, we recruited 104 4-year olds from Head Start classrooms; 52 children participated in a two-week training program, and 52 children were in a control group. Results indicated that children in the training program learned more words and were more likely to sort taxonomically than children in the control condition. Furthermore, the number of words learned over the training period predicted the extent to which children categorized taxonomically. Additionally, this ability to categorize taxonomically predicted the number of words learned outside the training program, over and above the number of words learned in the program. These results suggest a bi-directional relationship between conceptual organization and word learning.

Abstract We examined the effects of a morphological awareness (MA) training program on the enhancement of word and pseudo-word reading and phonological awareness in Arabic-speaking children with dyslexia. We compared two groups of children with dyslexia from Grade 3, an experimental group (n = 12; mean age = 112.4 months) with a control group (n = 13; mean age = 111.61 months). The training program focused on morphological analysis, derivational morphology and inflexional morphology. Results revealed that the experimental group outperformed controls on all post-training measures for MA, reading words and pseudo-words as well as phonological awareness. Also, the post-training measures were better achieved in the experimental group than pre-training ones, which confirm the efficacy of the morphological training program. We discuss these findings in light of the relationship between morphological awareness and word reading and phonological awareness, and the Arabic orthographic features as a morphological based language.

7 severely disturbed neuropsychiatric inpatients participated in a 12-session assertion training program as well as the normal hospital milieu therapy program. A matched group participated in only the normal hospital milieu therapy routine. All Ss were compared on the dependent measures of personal space and the Spielberger Self-evaluation Questionnaire 1 wk. before and 1 wk. after the assertion training program. The experimental group showed a significant reduction in both personal space and self-reported anxiety while the matched control group shewed no significant reduction. Small rhos indicate the need for further research examining the relationship between personal space and anxiety.

Abstract Background Although pain-related avoidance is mainly intended to reduce the accompanying anticipatory fear, avoidance behavior may paradoxically increase fear when a previous avoidance response is no longer available, suggesting that there is a bidirectional relationship between pain-related fear and avoidance. Purpose We hypothesized that avoidance can serve as a source of information that fuels irrational pain-related threat appraisals, which, in turn, increases pain-related fear. Methods Participants (N = 66) were exposed to a painful heat stimulus and randomly assigned to the avoidance or control group. They were instructed to avoid the full heat intensity by pressing a stop button in the presence of a stop cue. Only avoidance group participants received a stop cue and were allowed to press the stop button, while control group participants received the same instructions but never had the opportunity to avoid the full heat intensity. In reality and unknown to participants, the intensity and duration of the heat stimulus was independent of the avoidance response. In the subsequent test phase, the avoidance response was unavailable for both groups. We measured pain-related fear, threat appraisals/harmfulness, and pain intensity. Results In line with our expectations, pain-related fear levels were higher when the avoidance response was no longer available compared to those when the avoidance response was available. Increased threat appraisals mediated the relationship between avoidance behavior and increased pain-related fear. Conclusions The perceived opportunity to avoid increased pain-related fear through threat appraisals, suggesting a more complicated relationship between pain-related fear, threat appraisals, and avoidance behavior than the unidirectional relationships proposed in the fear-avoidance model. Clinical implications are discussed.

ABSTRACTThe purpose of this study was to assess the effect of short-term resistance training and two weeks of tapering on physical performances in handball players. Following a ten-week progressive resistance training program, subjects were divided between an experimental (n = 10) and a control group (n = 10). The experimental group completed a resistance training program, followed by a two-week period when the training intensity was tapered by 60%, while the control group maintained their typical pattern of training. Muscle power (force–velocity test and squat and counter-movement jump tests), sprinting ability (10m and 30m), ability to change direction (T-half test) and throwing velocity (a 3-step throw with a run, and a jump throw) were evaluated before training, at the end of training and after tapering. The experimental group showed significantly larger interaction effects for the 10-week training period (12/15, 80%), than for the following 2 weeks of tapering (10/15, 67%), with the largest gains being in 15 m sprint times (d=3.78) and maximal muscular strength in the snatch (d=3.48). Although the performance of the experimental group generally continued to increase over tapering, the mean effect size for the training period was markedly higher (d=1.92, range: 0.95-3.78) than that seen during tapering (d=1.02, range:−0.17-2.09). Nevertheless the ten weeks of progressive resistance training followed by two weeks of tapering was an effective overall tactic to increase muscle power, sprint performance and ball throwing velocity in handball players.

The Relationship

The aim of this study, which was carried out in the French-speacking part of Switzerland, was to examine the relationship between suicide attempts and self-mutilation by adolescents and young adults. The population, aged 14-25 years (N = 308), included a clinical sample of dependent subjects (drug abuse and eating disorders) compared to a control sample. On the basis of the Mini Neuropsychiatric Interview ( Sheehan et al., 1998 ), DSM-IV criteria were used for the inclusion of the clinical population. The results concerning the occurrence of suicide attempts as well as on self-mutilation confirm most of the hypotheses postulated: suicidal attempts and self-mutilation were more common in the clinical group compared to the control group, and there was a correlation between suicide attempts and self-mutilation. However, there was only a partial overlap, attesting that suicide and self-harm might correspond to two different types of behaviour.

The Relationship

The relationship and causality direction between electricity consumption and economic growth is an important issue in the fields of energy economics and policies towards energy use. Extensive literatures has discussed the issue, but the array of findings provides anything but consensus on either the existence of relations or direction of causality between the variables. This study extends research in this area by studying the long-run and causal relations between economic growth, electricity consumption, labour and capital based on the neo-classical one sector aggregate production technology mode using data of electricity consumption and real GDP for ASEAN from the year 1983 to 2012. The analysis is conducted using advanced panel estimation approaches and found no causality in the short run while in the long-run, the results indicate that there are bidirectional relationship among variables. This study provides supplementary evidences of relationship between electricity consumption and economic growth in ASEAN.

The Relationship

Background: Diabetes mellitus (DM) is a common metabolic disease worldwide and has many complications. The vascular events are the major complication of DM that have an important effect on mortality and disability. The physical activity (PA) enhances the vascular function by several pathways. The aim of this study was to evaluation of the relationship between PA and vascular diseases in patients with DM.Materials and Methods: This research was performed as the case-control study that was extracted from a prospective epidemiological research study in Iran (PERSIAN). The patients with type 2 DM more than six months defined as case group and the non-DM subjects in control group with ratio 1:2, and both groups were matched in the term of age and sex. The MET score was used to evaluate the level of PA and blood glucose, lipid profile, body mass index, overweight, dyslipidemia, glomerular filtration rate, myocardial infarction (MI), unstable angina, and stroke.Results: Overall, 1242 patients with DM were extracted, and 2484 non-diabetic subjects were investigated. In the case group, 355(28.6 %) and 887(71.4%) were men and women, respectively, the and 710 (28.6%) men and 1774(71.4%) women in control group. The mean MET score was 30 and 40.97 in the DM and non-DM groups, respectively (P˂0.001). The frequency of MI, stroke, and cardiac ischemia were 44 (3.5%), 37 (3%), and 267 (21.5%), respectively in DM group, and 54 (2.2%), 43 (1.7%), and 389 (15.7%), respectively in non-DM group.Conclusion: The incidence of vascular events associated with PA level in patients with DM and adherence to regular PA reduce the vascular events and DM complications.

The Relationship

We have explored the relationship between possible hemostatic changes and clinical manifestation of the systemic lupus erythematosus (SLE) as a function of greater or lesser disease activity according to Systemic Lupus Erythematosus Disease Activity Index-2000 (SLEDAI-2K) criteria. Endothelial injury and hypercoagulability were investigated in patients with SLE by measuring thrombomodulin (TM), D-dimer (DDi) and thrombin generation (TG) potential. A total of 90 participants were distributed into three groups: 1) women with SLE presenting with low disease activity (laSLE) (SLEDAI-2K ≤ 4), 2) women with SLE presenting with moderate to high disease activity (mhaSLE) (SLEDAI-2K > 4), and 3) a control group comprising healthy women. Levels of TM and DDi were higher both in the laSLE and mhaSLE groups compared to controls and in mhaSLE compared to the laSLE group. With respect to TG assay, lagtime and endogen thrombin potential, low concentrations of tissue factor provided the best results for discrimination among groups. Analysis of these data allow us to conclude that TM, DDi and TG are potentially useful markers for discriminating patients with very active from those with lower active disease. Higher SLE activity may cause endothelial injury, resulting in higher TG and consequently a hypercoagulability state underlying the picture of thrombosis common in this inflammatory disease.
