The Impact

The article renders findings of the study of the development of school children’s reading skills and motor development (n=61). Pedagogical and psychological literature considers visual, auditory, and cognitive impairments as primary causes of difficulties in devel-oping reading skills. It is generalized an idea that all types of perception (visual, auditory, etc.) are of afferent-efferent nature: each of these sensory processes is based on its own motor components. Thepurposeof the research is to analyze the impact of student’s motor skills disorders on mastering reading skills; to find the root of the disorders using neuropsychological tests; to differentiate errors and identify effective correction methods. Researchmethodsareasfollows:O. Luria Neuropsychological Battery adapted to school children by Glozman J.; child dyslexia test by O. Korniev & O. Ishymova. Research results have been processed through mathematical statistics, i.e., Pearson correlation coefficient and point-biserial correlation coefficient. Results. It has been identified the most significant indices of the functioning of the motor system of a child, which influence the progress of mastering reading skills in two age groups of school children (aged 7-9 and 10-12). The research has found the most fundamental errors made by school children while per-forming tests that are a ground for basic neuropsycho-logical correction. Conclusions.It has been substantiated that reading is a multi-factor process, and helping a pupil under some reading difficulties. It cannot be lim-ited to monotonous methods. The research states that neuropsychological diagnostics contributes to finding poorly-developed elements, which affect a child’s learning, discovering errors, and developing an effective intervention plan. The first step of the correction should comprise the work with the child motor system, as proved by this research. It is noted that a sensorimotor correction based on M. Bernstein’s construction of movements may underly the program.Keyw ords: neuropsychological diagnostics, dyslexia, learning difficulties, sensorimotor correction. У статті представлені результати дослідження сформованості навичок читання школярів та їхнього рухового розвитку (n=61). У педагогічній та психологічній літературі основними причинами труднощів формування навичок читання найчастіше визначають зорові, слухові та когнітивні проблеми. Розглянуто черговий чинник у структурі розвитку дитини – руховий розвиток. Узагальнено думку, що всі види сприйняття (зорове, слухове тощо) мають аферентно-еферентний характер, в основі кожного з цих сенсорних процесів беруть участь свої рухові компоненти. Метою дослідження є визначення впливу рухових проблем школяра у оволодіння навичками читання; розуміння причини цих проблем за допомогою нейропсихологічних проб; диференціація помилок і визначення ефективних методів корекції. Методидослідження: класична батарея нейропсихологічних тестів О.Лурії, адаптована до дітей шкільного віку Ж.Глозман; методика діагностики дислексії у дітей О.Корнєва і О.Ішимової. Здійснено обробку результатів методами математичної статистики, а саме – кореляційний аналіз за Пірсоном та точково-бісеріальних коефіцієнтів кореляції. Результати.Визначено найбільш значущі показники роботи рухової системи дитини, які мають вплив на успішність оволодіння навичками читання у двох вікових групах школярів (7-9 та 10-12 років). З’ясовано найбільш значущі помилки при виконанні проб школярами, що є підставою для базових напрямків нейропсихологічної корекції. Висновки.Обґрунтовано, що читання – багаточинниковий процес і допомога дитині при труднощах з ним не може обмежуватися одноманітними методами. Констатовано, що нейропсихологічна діагностика допомагає встановити чинники, які є несформованими і впливають на навчання дитини, диференціювати помилки і побудувати ефективний корекційний маршрут. Першим кроком корекції має бути робота з руховою сферою дитини, що доведено нашим дослідженням. Зазначено, що основою програми може бути сенсомоторна корекція на базі теорії про побудову і біомеханіку рухів М.Бернштейна. Ключовіслова: нейропсихологічна діагностика, дислексія, труднощі навчання, сенсомоторна корекція.

Excess Deaths

AbstractIn some chikungunya epidemics, deaths are not completely captured by traditional surveillance systems, which record case and death reports. We evaluated excess deaths associated with the 2014 chikungunya virus (CHIKV) epidemic in Guadeloupe and Martinique, Antilles. Population (784 097 inhabitants) and mortality data, estimated by sex and age, were accessed from the Institut National de la Statistique et des Études Économiques in France. Epidemiological data, cases, hospitalisations and deaths on CHIKV were obtained from the official epidemiological reports of the Cellule de Institut de Veille Sanitaire in France. Excess deaths were calculated as the difference between the expected and observed deaths for all age groups for each month in 2014 and 2015, considering the upper limit of 99% confidence interval. The Pearson correlation coefficient showed a strong correlation between monthly excess deaths and reported cases of chikungunya (R= 0.81,p< 0.005) and with a 1-month lag (R= 0.87,p< 0.001); and a strong correlation was also observed between monthly rates of hospitalisation for CHIKV and excess deaths with a delay of 1 month (R= 0.87,p< 0.0005). The peak of the epidemic occurred in the month with the highest mortality, returning to normal soon after the end of the CHIKV epidemic. There were excess deaths in almost all age groups, and excess mortality rate was higher among the elderly but was similar between male and female individuals. The overall mortality estimated in the current study (639 deaths) was about four times greater than that obtained through death declarations (160 deaths). Although the aetiological diagnosis of all deaths associated with CHIKV infection is not always possible, already well-known statistical tools can contribute to the evaluation of the impact of CHIKV on mortality and morbidity in the different age groups.

The aim of the study was to assess the value of multiparametric ultrasound in atherosclerotic cardiovascular disease risk screening of the carotid artery. We performed ultrasonography of carotid arteries in 96 adults in 3 age groups: senior (age ≥65 years, n = 44), middle age (age 45-64 years, n = 31), and young adults (age 20-44 years, n = 21). The senior group was then divided into subgroups: athletes (n = 21) and non-athletes (n = 23). Ultrasound parameters included carotid intima-media thickness, distensibility coefficient, and presence of plaque(s). Statistical analyses included one-way analysis of variance with post hoc to analyze the differences in ultrasound parameters among the age groups; unpaired t-test to examine differences between hypertensive and normotensive participants, between seniors with and without plaque(s), and between senior athletes and non-athletes; Pearson correlation coefficient to analyze correlations of ultrasound parameters to age and blood pressure; and intraclass correlation coefficient to test intra- and inter-observer reliability in performing multiparametric ultrasound. Carotid intima-media thickness and distensibility coefficient significantly differed among the 3 age groups and between athletes and non-athletes ( P < .001). Senior athletes had greater distensibility than non-athletes (all Ps < .05). Carotid intima-media thickness was increased and distensibility was reduced with age and hypertension. Age and blood pressure positively correlated with carotid intima-media thickness (Pearson correlation coefficient, r > .21) and negatively with distensibility coefficient (Pearson correlation coefficient, r < –.48). Inter- and intra-observer reliability in performing multiparametric ultrasound was good (intraclass correlation coefficient, r > .81). Multiparametric ultrasound is a useful tool to assess carotid artery function and morphology comprehensively.

ObjectivesTo assess the impact of a biplanar ascending opening-wedge high tibial osteotomy (OWHTO) on the alignment of the knee extensor mechanism and patellar height using preoperative and postoperative MRI.MethodsMedical records of all patients submitted to ascending biplanar OWHTO between July 2008 and March 2017 were retrospectively assessed. Five parameters of the patellofemoral joint—tibial tubercle–trochlear groove distance (TT-TG), patellofemoral (PF) axial engagement index, lateral patellar tilt, Blackburne-Peel index (BPI) and Caton-Deschamps index (CDI)—were measured by two blinded independent observers on both preoperative and postoperative MRIs. Interobserver reliability was assessed with the intraclass correlation coefficient (ICC). Paired t-test was performed to compare preoperative and postoperative measurements. The association of the amount of HTO opening and the assessed PF joint parameters was also investigated with Pearson correlation coefficient.Results26 patients who underwent ascending biplanar OWHTO were enrolled in this imaging analysis (63.4%) with a mean follow-up of 16.3 months (SD, 16.9). ICC for all measurements ranged between 73.3% and 89.3%. Postoperatively, TT-TG distance significantly increased by 2.0 mm±2.3 mm (p<0.001). Patellar height significantly decreased when evaluated by the BPI (p<0.001) and CDI (p=0.001). The amount of osteotomy opening significantly correlates with the postoperative BPI (p=0.023) and CDI (p=0.013).ConclusionThis study comprehensively reports significant increase on TT-TG distance after an ascending biplanar OWHTO using MRI. Small but significant decreases in patellar height were also observed and are correlated to the amount of axis correction.Level of evidenceLevel IV, retrospective case study.

The Impact

Explanations about the surrounding world are of particular significance for children since it is a way for them to learn and cognise the environment. However, Legare (2014) maintains that little is known about the impact of explanations on learning. For the past decade, explanations have been one of the major themes in the studies of cognitive psychology. They aim at answering the key questions: what is the nature of the phenomenon (explanation), what is it composed of, what are its quality criteria, how is it constructed and perceived by children (Lombrozo, 2006). Hence, the aim of the current paper is to explore the ability of pre-school and primary school children to assess the quality of explanations. The aforesaid aim was posed in accordance with the methodology developed by the authors (the methodology was designed with reference to the study of Baum, Danovitch, and Keil (Baum et al., 2008). The research involved 61 children: 20 pre-school children, and 41 primary school children (21 children of the second grade, and 20 children of the fourth grade respectively). The main conclusions of this research are: – children’s ability to assess the quality of explanations increases from pre-school age to the second grade of primary school, yet at this period, it remains unchanged (from the second to fourth grade); – despite that the ability to assess the quality of explanations on familiar and unfamiliar topics differs in both age groups (pre-school and primary school), the differences are not statistically significant. It has been determined that, assessing explanation on familiar and unfamiliar topics, pre-school children and fourth grade pupils are able to distinguish circular explanations on familiar topics in a more similar way than assessing explanations on unfamiliar topics. Moreover, older primary learners are more precise in assessing explanations on familiar rather than unfamiliar topics; – the oldest children (fourth grade learners) choose a noncircular explanation as a better one more knowingly and reasonably. Meanwhile, children of pre-school age and second grade pupils cannot often point out why they have chosen a noncircular explanation; – only older children (mostly fourth grade pupils and several second grade learners) are able to recognise and identify the structure of a circular explanation. The conducted research provides insights into the ability of small children to assess the acquired information. It is noteworthy that the assessment and creation of explanations is one of the mechanisms of learning and development (Bonawitz et al., 2008; Legare, & Lombrozo, 2014). Hence, their impact is obvious: explanations give a basis for learning, whereas prior knowledge is fundamental for explanations (Williams, & Lombrozo, 2013).

This chapter contributes to the study of uncertainty of signal dimensions within a microscopic image of blood sample. Appropriate colocalization indicator classifies the leukocytes in the region of interest having ragged boundaries. Signal transduction has been interpreted using correlation function determined fluorescence intensity in proposed work using just another colocalization plugin (JaCoP). Dependence between the channels in the colocalization region is being analysed in a linear fashion using Pearson correlation coefficient. Manders split, which gives intensity, is represented in a channel by co-localizing pixels. Overlap coefficients are also being analysed to analyse coefficient of each channel. Li's intensity correlation coefficient is being used in specific cases to interpret the impact of staining.

Abstract This study investigates the impact of petrophysical rock properties on the velocity-pressure relationship in carbonates. It presents an approach to predict the changes in compressional velocity (Vp) as function of pressure in carbonates. The approach honors the complexity of carbonates by incorporating various petrophysical rock properties including bulk density, porosity, mineralogy and pore stiffness. The data used in this study consists of rock properties (density, porosity, mineralogy) and elastic velocity measured as function of confining pressure for 220 carbonate core plug samples from published literature. Pearson correlation coefficient was calculated to evaluate the significance of each property in predicting velocity-pressure relationship. A simple regression was formulated incorporating all significant input rock properties to predict Vp as function of pressure based on initial measured velocity at a given pressure. The predictions were compared with the measured Vp. The results show that the sensitivity of Vp to changes in pressure increases as the porosity and pore compressiblity increases. On the other hand, samples with higher bulk density and Vp / Vs ratio (at initial lowest pressure) show little Vp variations as function of increasing pressure. High Vp / Vs values are observed in samples that are well cemented and have less clay or silisiclastic fraction. Such characteristics reduce the compressibility of pores leading to non-variable velocity-pressure relationship. Incorporating the rock properties in regression analysis could successfully predict Vp as function of pressure with a correlation coefficient of 0.99 and average absolute error of less than 3%. Since all input parameters (rock properties) can be estimated from well logs, the presented approach can potentially be used to predict in-situ changes in Vp due to pressure changes. This can assist the interpretation of time lapse seismic, and in geomechanics-related applications.

IntroductionWorld studies show associations between social consequences of carers’ involvement and level of individuals’ met and unmet needs.ObjectivesIn Poland not much interest has been put to studies of psychiatric patients’ needs and carers’ burden. Due to this fact most of care programmes have been developed on the basis of authors’ personal experiences or academic knowledge.AimsTo obtain data regarding met and unmet patients’ needs and the impact on carers’ burden in Polish socioeconomic reality.Methods60 psychotic inpatients were examined with CSHI, BPRS and CANSAS. Their 60 direct carers’ personally completed IEQ, GHQ-12 and assessed own opinions about patients’ needs with CANSAS questionnaire. Patients unable to give informed consent, alcohol/drug dependent, mentally retarded/demented or with personality disorder were excluded along with patients below 18 and over 65 years of age.Statistics includedThe Pearson correlation coefficient, the Spearman’s rank correlation coefficient, Kendall’s tau coefficient.ResultsResults show significant relation between duration of the disorder and number of unmet needs assessed by individuals. Patients’ met needs are positively associated with carers IEQ results - subscales tension and worrying. Carers evaluation of patients’ unmet needs correlates with their IEQ results - subscales tension, worrying and urging. Overall number of patients’ needs indicated by carers correlates positively with carers’ results of IEQ subscale - urging.ConclusionsThe higher rate of patients’ unmet needs the higher burden they are imposed to. Results of the study are important in planning of interventions towards psychiatric patients and their direct carers.

In today's world, human capital is considered as the highest and most valuable asset of an organization, which affects the profits and losses of any company. The organizations that exist in these societies must be able to utilize human resources effectively. Job rotation is one of the management measures in the field of human resource management. It can create a creative, ideal, and secure organization that ensures commitment, knowledge transfer, skills acquisition, innovation, creativity, experience, job satisfaction, enthusiasm, exhaustion reduction, and human capital growth. The aim of this study is to investigate the effect of job rotation system on work motivation (studied in the region of two gas transfer operations). The present study is a correlation from the field and in terms of purpose and nature of application and in terms of descriptive-survey method and in terms of cross-sectional time. The statistical population of the study is 850 personnel (managers, experts and employees) of the region of two gas transmission operations. Using Cochran's formula, the sample size for limited communities is 285 people. The statistical population of the study consists of heterogeneous groups (formal and informal forces, managers and employees) using stratified random sampling method. In order to collect data, a researcher-made questionnaire with 20 items and a standard job motivation questionnaire with 17 items were used. The questionnaire is divided based on a five-point Likert scale. Reliability and validity were calculated and the value of 0.881 was obtained, which indicates the appropriate reliability of the questionnaires. To investigate the relationship and research hypotheses, Pearson correlation coefficient and regression, SPSS software and LISREL software were tested. The results show that the dimensions of job rotation such as human capital development and changes in human capital are related to work enthusiasm. Pearson correlation coefficient is 0.842 and 0.368, respectively, which indicates a good correlation. Also, the development and changes of human capital have a significant effect on job motivation and the standard beta value was 0.343 and 0.281, respectively, and all research hypotheses have been confirmed.
