The Relationship

Assessment of semantic processing capacities often relies on verbal tasks which are, however, sensitive to impairments at several language processing levels. Especially for persons with aphasia there is a strong need for a tool that measures semantic processing skills independent of verbal abilities. Furthermore, in order to assess a patient’s potential for using alternative means of communication in cases of severe aphasia, semantic processing should be assessed in different nonverbal conditions. The Nonverbal Semantics Test (NVST) is a tool that captures semantic processing capacities through three tasks—Semantic Sorting, Drawing, and Pantomime. The main aim of the current study was to investigate the relationship between the NVST and measures of standard neurolinguistic assessment. Fifty-one persons with aphasia caused by left hemisphere brain damage were administered the NVST as well as the Aachen Aphasia Test (AAT). A principal component analysis (PCA) was conducted across all AAT and NVST subtests. The analysis resulted in a two-factor model that captured 69% of the variance of the original data, with all linguistic tasks loading high on one factor and the NVST subtests loading high on the other. These findings suggest that nonverbal tasks assessing semantic processing capacities should be administered alongside standard neurolinguistic aphasia tests.

One of the most important factors of management in obtaining organization targets is effectiveness of financial management structures, and user of the financial management structures have more important role in the effectiveness of the structures. The purpose of this research is to study the influence of human factors including personal and individual characteristics of user of financial management structures based on effectiveness PC. For this target, a sample includes 2354 offices, organizations, private companies and organizations than apply financial management structure based-PC. Has been selected randomly and the investigative data has been counting using questionnaires. In order to find personal characteristics of users, the particular questionnaires which are designed according to four factor model of personality, has been done. In order to research the relation between effectiveness of the structure and personality, four hypotheses based on four features of personality. Moreover, in order to find the relationship between expertise (educational level, educational field and amount of training curriculum of PC knowledge), job satisfaction and experience of users, and effectiveness of the accountancy management structure based-PC, some hypotheses have been studied and written. The study results indicates that personal characteristics including Agreeableness, openness, Conscientiousness and experience working , is efficient on the financial management structures based-PC.

The Relationship

This study examines the relationship between self-perceived emotional intelligence (EI) measured by the Emotional Intelligence Scale (EIS) [1] and other personality measures including the five-factor-model. The EI construct has lately been re-defined as the ability to think intelligently about emotions and to use them to enhance intelligent thinking [2]. Two studies provide support that self-reported EI is mainly associated with personality traits (extraversion, agreeableness, conscientiousness, self-perceived creativity), life satisfaction and thinking styles with only a low relation to verbal intelligence. Furthermore, persons higher in the EI dimension “emotional efficacy” produced more creative performances than persons low in this domain. These findings suggest that self-reported EI cannot be considered as a rational form of intelligence so that it does qualify to fit into the framework of personality traits.

The present study investigates whether social support mediates the relationship between personality traits and physical functioning among African Americans over 2.5 years. Data were collected from a national probability sample of African American adults (analytic sample N = 312). Telephone surveys included measures of the five-factor model personality traits, social support, and physical functioning. Personality traits were assessed at Time 1 (T1), and social support and physical functioning were assessed 2.5 years later at Time 2 (T2). Physical functioning was assessed using the SF-12 at T2. Results indicated that T2 social support mediated the relationship between T1 personality traits and T2 physical functioning for the traits of conscientiousness, extraversion, agreeableness, and neuroticism, but not for openness to experience. This information may be useful to healthcare providers and community members in developing strategies targeting personality traits in cultivating social support for health promotion.

Abstract The identification of talent in soccer is critical to various programs. Although many research findings have been presented, there have been only a few attempts to assess their validity. The aim of this study was to determine the relationship between talent and achievement variables in the Vienna Test System. The participants were 91 Czech soccer players, representing four youth soccer teams, who were born in the year 2000. These boys were divided into two groups according to their coaches’ assessments using a TALENT questionnaire. A two-factor model (component 1: “kinetic finesse”; component 2: “mental strength”) was designed to interpret the responses of the coaches on the questionnaire. The Vienna Test System was used to determine the level of players’ cognitive abilities. In total, the subjects performed seven tests in the following order: Raven’s Standard Progressive Matrices (SPM), a reaction test (RT), a determination test (DT), a visual pursuit test (LVT), a Corsi Block-Tapping Test (CORSI), a time/movement anticipation test (ZBA), and a peripheral perception test (PP). To analyze the relationship between talent and achievement variables within the Vienna Test System, correlation analyses were performed. The results revealed that the talented group attained significantly better results on only 1 of the 16 variables, which was ZBA2: movement anticipation - deviation of movement median (r = .217, p = .019). A comparison of the two talent components showed that component 1 (“kinetic finesse”) was a more significant factor than component 2 (“mental strength”). Although we observed statistically significant correlations, their actual significance remains questionable; thus, further research is required.

PurposeThis paper is an attempt to explore the fact that whether the literature-promised value premium has any sector orientation. The paper tests the relationship between the value premium and Indian sectors: fast-moving consumer goods (FMCG), financials, healthcare, information technology (IT), manufacturing and miscellaneous.Design/methodology/approachThe paper analyses around 210–480 companies listed on BSE-500 for the period of the recent 18 years ranging from March 1999 to March 2017. The paper employed Welch's ANOVA to examine whether the price-to-book market ratio is significantly different across sectors. Two prominent asset pricing models – single factor market model and Fama–French three-factor model – were used to examine the existence of value premium within sectors for full period and two sub-periods.FindingsThe empirical results of the paper suggest that the difference in the P/B ratio both between sectors and within sectors is statistically significant. The results further suggest that the value premium exists within the sectors irrespective of their value-growth orientation.Research limitations/implicationsThe paper is not free from certain limitations. Firstly, due to the non-availability of data in the public domain, the time period before 1999 could not be considered. Secondly, the study has used data pertaining to the Indian stock market only. To add to it, our study has concentrated on BSE-500 companies only; however, the future researchers can include both NSE and BSE companies.Practical implicationsThe paper has important implications for portfolio managers and retail investors following a top-down approach of investing. The portfolio manager can strategically build up the portfolios to concentrate more on the companies belonging to sectors like healthcare, manufacturing and FMCG. Investors following the top-down approach should avoid the underperforming growth stocks belonging to the growth sectors and allocate their funds to value stocks in the growth sector.Originality/valueThe paper is first of its kind to study the relationship between the value premium and Indian sectors. The paper contributes to portfolio management and asset pricing literature for an emerging market.

Positive And Negative Symptoms

BackgroundControversy surrounds the relationship between tardive dyskinesia (TD) and symptoms of schizophrenia. While some studies reported that negative symptoms of schizophrenia may be a risk factor for TD, others reported a relationship between TD and positive symptoms.MethodEighty-four patients were studied, of whom 47 met criteria for TD. Clinical and instrumental procedures were used to increase the sensitivity of our assessments of the presence and severity of TD. Stepwise logistic and linear regression procedures were used to identify demographic variables, psychopathology, and motor parameters associated with the presence and severity of TD.ResultsA 3-factor model consisting of age, clinical tremor, and negative symptoms explained 25% of the variance in clinical TD severity. A 6-factor model consisting of female gender, instrumental and clinical measures of parkinsonism, positive, and negative symptoms explained 49% of the variance in severity of instrumentally derived dyskinesia.ConclusionsThese results suggest that the presence of TD may be associated with positive symptoms; that the severity of TD may be related to negative symptoms; and that the relationship between negative symptoms and TD severity may be influenced by the presence of parkinsonism.

The Relationship

Orientation: Organisational climate and job satisfaction are distinct but related constructs, and both appear to influence employees’ understanding of the work environment and their level of job satisfaction.Research purpose: The objective of this study was to explore the relationship between organisational climate and job satisfaction to determine whether employees’ perceptions of the work environment influence their level of job satisfaction.Motivation for the study: Organisations are facing more challenges than ever before. These challenges are not unique to any specific organisation or industry, but affect all organisations.Organisational climate in particular is constantly challenged by changes impacting organisations today.Research design, approach and method: An organisational climate questionnaire was administered to a convenience sample of 696 employees from a population of 1453 employees working in three regions in which the organisation was operational. Confirmatory and exploratory factor analyses were used to investigate the structure of the climate model.Main findings: The revised 12-factor model (after the confirmatory factor analysis) fitted the data best and the researchers therefore decided to proceed with the revised 12-factor model (11 dimensions) for further analysis. A stepwise regression was conducted and nine dimensions of organisational climate were found to predict job satisfaction. The results indicated a strong positive correlation (r = 0.813, p< 0.01) between organisational climate and the dependent variable of job satisfaction.Practical implications: This study provided support for the view that line managers and human resource practitioners should be aware that different biographical groups have different needs that can influence their job satisfaction levels and different perceptions of the climate within the organisation and that this impacts on their behaviour.Contribution: The findings of this study indicated a positive relationship between organisational climate scores and job satisfaction scores and thus, regardless of how the dimensions are perceived, organisational climate has an influence on job satisfaction.

Rule Out

In the framework of a two-good, two-factor model it is evident that the pattern of trade can be inferred from the change in commodity prices resulting from the opening of trade. Thus, if trade increases the relative price of a commodity, we expect that commodity to be exported, while the good whose relative price decreases will be imported. Under certain circumstances however, it may be possible to observe a country importing a commodity even though its free trade relative price is higher than under autarky. The purpose of this paper is to point out that a similar paradox can be established even if we rule out distributional effects of changes in commodity prices on the demand for goods attributable to different tastes. In particular, we focus our attention on a simple three-good, two-factor model with fixed production coefficients. It is well known that when the number of goods exceeds the numbers of factors, a basic indeterminacy exists in the relationship between output levels and relative commodity prices. Our interest lies in establishing that one application of this indeterminacy is that technological characteristics—in particular, the factor intensity ranking of commodities and a country's factor endowment—may result in the reversal of the expected pattern of trade.
