In the study metric characteristics of children aberrant behavior questionnaire were analyzed. The analysis was performed on the sample of 1.165 children, aged 4-7, in preschool institutions in several towns of Vojvodina. The questionnaire contained 36 items of the Likert-type scale and was filled in by one parent of each child. The authors examined main metric characteristics of the complete questionnaire, as well as individual items under the Rasche?s measurement model. Generally, parents seldom notice aberrant behavior in their children. Most frequently they notice stubbornness, while very rarely torturing of animals. The item discrimination, on the whole, was found satisfying. The reliability of the questionnaire is 0.84., and all indicators of misfit are within satisfactory ranges. According to differential functioning of the items, the authors found gender and age specificities of parents? evaluation of aberrant behavior of their children. Parents often notice stubbornness and moldiness in girls, and aggression in boys. According to the parent?s observations, younger children are characterized by nail nibbling, ticklishness, and fearfulness, whereas older children show a tendency to force their way by crying, waywardness and bed-wetting. By means of factor analysis of the items, three principal facets of aberrant behavior were determined: overindulgence, shyness and quarrelsomeness. Cross validation (hold out) showed that these three facets were robust in relation to the selection of the sample.

The sample included 712 preschool boys and girls at the age of 4 to 7 years (mean 5.96 decimal years and standard deviation .96) from preschool institutions in Novi Sad, Sombor, Sremska Mitrovica and Backa Palanka. Information concerning 36 indicators of aberrant behavior of the children were supplied by their parents, whereas their cognitive ability was tested by Raven?s progressive colored matrices. Based on factor analysis (promax method), four factors i.e. generators of aberrant behavior in children were singled out: aggression, anxiousness, dissociation, and hysteria, whose relations with cognitive functioning and age were also analyzed by factor analysis. Aberrant behavior and cognitive abilities show significant interrelatedness. Owing to orderly developed cognitive abilities, a child understands essence and reality of problems, realizes possibilities and manners of solving them, and succeeds in realizing successful psycho-social functioning. Developed cognitive abilities enable a child to recognize and understand her/his own reactions in different situations and develop manners of reacting, which leads to strengthening psycho-social safety and adapting behavior in accordance with her/his age and abilities.

Comprehension Deficit

Tests to measure comprehension, formulation, and repetition of certain phonologic, syntactic, and semantic aspects of language were administered to 47 children who had developmental language disorders. A factor analysis of the resultant scores indicated that three factors were present in the data. These factors are presented as six patterns of language performance, one for high loadings on the factor and one for low loadings. The six patterns are (1) repetition strength (Factor I, high); (2) nonspecific formulation-repetition deficit (Factor I, low); (3) generalized low performance (Factor II, high); (4) phonologic comprehension-formulation-repetition deficit (Factor II, low); (5) comprehension deficit (Factor III, high); and (6) formulation-repetition deficit (Factor III, low). Possible relations among these patterns and nonlinguistic measures (sex, race, age, nonverbal intelligence, socioeconomic status, and status of the peripheral speech mechanism) were investigated. Two of the patterns of language performance were found to be related significantly to age. On Factor II, the younger children tended to get high loadings (generalized low performance) while the older children tended to get low loadings (phonologic comprehension-formulation-repetition deficit).

The purpose of the current study was to investigate the preliminary development and validation of the Subjective Academic Wellbeing Measure (SAWM), which is a six-item self-report rating measure intended for use as a screening tool to assess the positive academic functioning of young people within the elementary and high school context. Exploratory factor analysis was performed with Sample 1 (N= 161), indicating that the SAWM was characterized by a unidimensional measurement model and had strong factor loadings. Results from confirmatory factor analysis, which was carried out with Sample 2 (N= 199), confirmed the measurement model by yielding good data-model fit statistics that were characterized by strong latent construct and internal reliability estimates. Further analyses showed that the scale had good convergent validity considering scores from several self-reported scales of student mental health problems and positive school functioning. Further analyses also showed that configural, metric, and scalar measurement invariance were observed across gender groups. These results provide initial evidence suggesting that the SAWM is a reliable and valid measure that can be used to assess the positive academic functioning of students within the school context. Implications are discussed, and some suggestions are provided for future research and practice

Entrepreneurial Activities

Entrepreneurial orientation (EO) refers to entrepreneurial activities of established and existing firms. It is different from individual entrepreneurial orientation (Popov et al., 2019, Education + Training, vol. 61, pp. 65–78). EO refers to the processes, practices, and decision-making activities that lead to new venture creation (Walter et al., 2006, Journal of Business Venturing, vol. 21, pp. 541–567). The EO scale by Lumpkin and Dess (1996, Academy of Management Review, vol. 21, pp. 135–172) consists of innovativeness, proactiveness, risk-taking, competitive aggressiveness, and autonomy. This scale is widely used in literature with major drawback of it being developed and evaluated in a developed economy (the USA) on large corporations. Very little literature is available with reference to validation of EO scales in developing economies, particularly India where firms are generally small. New Comprehensive Entrepreneurial Orientation Scale (CENTORES) has been developed and validated by adding additional dimension of strategic flexibility, which is the novelty of the present study. Data were collected using a survey instrument comprising of 19 items. The scientific scale development procedure as suggested by Schwab, (1980) was followed, first an exploratory factor analysis (EFA) was done to explore factors and later confirmatory factor analysis (CFA) was done to confirm factors (using SPSS and Amos). Six stable factors emerged from EFA which were subsequently confirmed through CFA. The measurement model confirmed the factors with good model fit indices as suggested by Hair et al. (2014). The model has CMIN/df = 2.237, CFI = 0.917, GFI = 0.928, NFI = 0.882, and RMSEA = 0.052

This paper presents a new gender and age classification system based on Electroencephalography (EEG) brain signals. First, Continuous Wavelet Transform (CWT) technique is used to get the time-frequency information of only one EEG electrode for eight distinct emotional states instead of the ordinary neutral or relax states. Then, sequential steps are implemented to extract the improved grayscale image feature. For system evaluation, a three-fold-cross validation strategy is applied to construct four different classifiers. The experimental test shows that the proposed extracted feature with Convolutional Neural Network (CNN) classifier improves the performance of both gender and age classification, and achieves an average accuracy of 96.3% and 89% for gender and age classification, respectively. Moreover, the ability to predict human gender and age during the mood of different emotional states is practically approved.

The investigation reported here was concerned with the application of the factor analytic method to identify the factors which define oral communication abilities in older children. A study population of 143 preadolescent subjects was evaluated on 40 speech and language measures by classroom teachers and by speech specialists. An intercorrelation matrix of the 40 measures was computed and submitted to a factor analysis by means of the principal axes method. Seven factors were extracted which represent the human abilities underlying the dimensions of speech and language behavior studied. The factors were identified as follows: Factor 1—General Speaking Ability as Assessed by Speech Specialists; Factor 2—Motor Skill in Speaking; Factor 3—Speech Dominance; Factor 4—Non-distracting Speech Behavior; Factor 5—Voice Quality; Factor 6— Language Maturity; and Factor 7—General Speaking Ability as Assessed by Teachers.

Proper selection of donor’s blood group is essential to prevent transfusion hazards. It is known that ABO antigen is fully developed at birth but the newborn baby does not produce ABO antibodies until 3 to 6 months of age. The ABO antibodies present in the serum of newborn babies are derived from mother’s blood due to placental transfer. So the blood group of the newborn baby is done by ABO antigen grouping (forward grouping) only, antibody grouping (reverse grouping) is not required. In case of transfusion of blood in newborn under 4 months of age, cross-matching of donor’s blood is done with the mother’s blood if it is available. We know, recipient’s same group of blood is always preferable in case of transfusion in adults or older children. But selection of blood for transfusion in the infants under 4 months of age depends on the mother’s blood group as well. If the mother’s blood group differs from the infant’s blood group, the infant’s same group of blood may not be selected for transfusion. For example, if the mother’s blood group is “O” and the newborn blood group is “A” or “B”, infant’s same group “A” or “B” group blood could not be transfused, because the anti-A & anti-B antibodies can be derived in the infant’s serum from mother’s blood which may react with the “A” or “B” antigen of the donor’s blood. In this case “O” group packed RBCs should be selected for transfusion. “O” group whole blood may contain IgG anti-A and anti-B antibodies in the plasma which can react with the “A” or “B” antigen of the infant’s blood. So to avoid anti-A & anti-B antibodies in “O” group, plasma should be discarded and the packed RBCs should be transfused. In case of Rh-negative mother with Rh positive baby, Rh antibody may develop in mother’s blood and Rh antibody may enter into baby’s circulation, in this case the infant should be transfused with Rh-negative blood to avoid Rh antigen & antibody reaction. So for the selection of blood for transfusion in newborn baby up to the age of 4 months mother’s blood group is important to select the appropriate blood.

Abstract Background There is a dearth of instruments that have been developed and validated for use with children living with HIV under the age of 17 years in the Kenyan context. We examined the psychometric properties and measurement invariance of a short version of the Berger HIV stigma scale administered to perinatally HIV-infected adolescents in a rural setting on the Kenyan coast. Methods A cross-sectional study was conducted among 201 perinatally HIV-infected adolescents aged 12–17 years between November 2017 and October 2018. A short version of the Berger HIV stigma scale (HSS-40) containing twelve items (HSS-12) covering the four dimensions of stigma was evaluated. The psychometric assessment included exploratory factor analysis, confirmatory factor analysis (CFA), and multi-group CFA. Additionally, scale reliability was evaluated as internal consistency by calculating Cronbach’s alpha. Results Evaluation of the reliability and construct validity of the HSS-12 indicated insufficient reliability on three of the four subscales. Consequently, Exploratory Factor Analysis (EFA) was conducted to identify problematic items and determine ways to enhance the scale’s reliability. Based on the EFA results, two items were dropped. The Swahili version of this new 10-item HIV stigma scale (HSS-10) demonstrated excellent internal consistency with a Cronbach alpha of 0.86 (95% confidence interval (CI) 0.84–0.89). Confirmatory Factor Analysis indicated that a unidimensional model best fitted the data. The HSS-10 presented a good fit (overall Comparative Fit Index = 0.976, Tucker Lewis Index = 0.969, Root Mean Square Error of Approximation = 0.040, Standardised Root Mean Residual = 0.045). Additionally, multi-group CFA indicated measurement invariance across gender and age groups at the strict invariance level as ΔCFI was ≤ 0.01. Conclusion Our findings indicate that the HSS-10 has good psychometric properties and is appropriate for evaluating HIV stigma among perinatally HIV-infected adolescents on the Kenyan coast. Further, study results support the unidimensional model and measurement invariance across gender and age groups of the HSS-10 measure.

Speech in noise tests that measure the perception of speech in presence of noise are now an important part of audiologic tests battery and hearing research as well. There are various tests available to estimate the perception of speech in presence of noise, for example, connected sentence test, hearing in noise test, words in noise, quick speech-in-noise test, bamford-kowal-bench speech-in-noise test, and listening in spatialized noise-sentences. All these tests are different in terms of target age, measure, procedure, speech material, noise, normative, etc. Because of the variety of tests available to estimate speech-in-noise abilities, audiologists often select tests based on their availability, ease to administer the test, time required in running the test, age of the patient, hearing status, type of hearing disorder and type of amplification device if using. A critical appraisal of these speech-in-noise tests is required for the evidence based selection and to be used in audiology clinics. In this article speech-in-noise tests were critically appraised for their conceptual model, measurement model, normatives, reliability, validity, responsiveness, item/instrument bias, respondent burden and administrative burden. Selection of a standard speech-in-noise test based on this critical appraisal will also allow an easy comparison of speech-in-noise ability of any hearing impaired individual or group across audiology clinics and research centers. This article also describes the survey which was done to grade the speech in noise tests on the various appraisal characteristics.
