Lighting Systems

The development of technologies associated with energy efficiency and use in lighting systems, arise as problems in the application of smart devices in different places such as: houses, buildings, industries, companies and public and private institutions. The objective of the study was to validate the instrument and the information obtained on the use of intelligent devices such as automatic control in a lighting system and its improvement in energy efficiency in the public sector. As a research methodology, a field study was conducted, based on a survey applied to 231 employees (bosses and workers) who work in 17 public institutions located in 6 cantons of the province of Manabí, Republic of Ecuador. To validate this instrument, an exploratory and confirmatory factorial analysis of the data obtained was carried out. As a result of the principal component analysis, a factor transformation matrix (0.870) was obtained and the reliability analysis was obtained (0.880) in relation to the reagents that describe three dimensions established in knowledge, application and technology management. It is concluded that the factor analysis applied through the KMO test, Bartlett's sphericity and Cronbach's alpha coefficient, with a correlation range ≥ 0.5 between reactants was feasible, which allows to certify the reliability and validity applied in this instrument.

Bullying among children and adolescents can have detrimental effects on their physical and mental health. The first step in the identification of bullying is the detection of relevant signs and behaviours, with the use of appropriate instruments. The widely used Peer Relation Questionnaire (PRQ)has been developed to measure bullying behaviour in children and adolescents. The aim of this study was to translate and validate this instrument in the Greek language in a school sample of children and adolescents. Α sample of 193 students (mean age ± SD 11.44 ± 1.26 years, girls 49.7%), was recruited from elementary and junior high schools of the public and private sector, in the capital of Athens, Greece. Along with the Peer Relation Questionnaire, the Stress in Children questionnaire and a structured inquiry regarding satisfaction from various aspects of life were used to assess the criterion validity of the Peer Relation Questionnaire. Results revealed good psychometric properties of the questionnaire in the Greek language. The principal component analysis resulted in two subscales that demonstrated an adequate internal consistency and a significant correlation with stress and satisfaction parameters, suggesting satisfying criterion validity. Meaningful associations between demographic characteristics and the subscales were also found. The Greek version of the Peer Relation Questionnaire-short form can be used as a valid tool to measure bullying behaviour in children and adolescents.

Trust Scale

<div><p><em>A The Employee Trust Scale is developed for a study that examines employees’ trust towards their supervisors. This 49-item measure is a newly created scale by the researchers based on the findings of their previous study “Exploring the Concept of Trust in Malaysia Society”. Through the result of exploratory factor analysis, Chua et al. (2015) was able to extract three factors, labeled ‘trustworthiness, ‘position status’and ‘relationship’ which accounted for 62.49% of the total variance and the scale provided reliable assessment. Considering the existing assumptions of three dimensions of employee trust toward their supervisor as established by Chua et al. (2015), in this paper, a confirmatory factor analysis was conducted to test the dimensionality of the Employee Trust Scale. This analysis was conducted with Structural Equation Modelling which was used to assess the fit of the model. In addition, reliability and validity of the model was measured. A total of 514 (274 males and 228 females) employees who were selected randomly from public and private organization sectors in Kota Kinabalu, Sabah, Malaysia were involved in this study. Their ages ranged from 21 to 59 years old with an average of 34.34 years old and their average tenure with their current organization was 8.46 years (with s.d. = 8.11 years). Finding of the present research can help in enhancing productivity within an organization by improving trust and relationship building between employees and employer.</em></p></div>

Abstract. Varimax rotated principal component scores (VRPCS) have previously been offered as a possible solution to the non-orthogonality of scores for the Big Five factors. However, few researchers have examined the reliability and validity of VRPCS. To address this gap, we use a lab study and a field study to investigate whether using VRPCS increase orthogonality, reliability, and criterion-related validity. Compared to the traditional unit-weighting scoring method, the use of VRPCS enhanced the reliability and discriminant validity of the Big Five factors, although there was little improvement in criterion-related validity. Results are discussed in terms of the benefit of using VRPCS instead of traditional unit-weighted sum scores.

The aged population of the world is increasing by a large factor due to the availability of medical and other facilities. As the number grows rapidly, requirements of this segment of age (65+) are increasing rapidly as well as the percentage of aged persons living alone is also increasing with the same rate due to the inevitable socio-economic changes. This situation demands the solution of many problems like loneliness, chronic conditions, social interaction, transportation, day-to-day life and many more for independent living person. A large part of aged population may not be able to interact directly with new technologies. This sought some serious development towards the use of intelligent systems i.e. smart devices which helps the people with their inability to use the available as well future solutions. Ambient Assisted Living (AAL) is the answer to these problems. In this paper, issues related to AAL systems are studied. Study of challenges and limitations of this comparatively new field will help the designers to remove the barriers of AAL systems.

This chapter considers two different ways of organizing revenue collection in statutory healthcare schemes: social health insurance and taxation. The two models are commonly referred to as ‘Bismarck vs Beveridge’ after the men associated with the origin of these systems: the first German chancellor Otto von Bismarck (1815–1898), and the British economist Lord William Beveridge (1879–1963). The differences between these two compulsory prepayment schemes are discussed and compared with private health insurance. Based on a simple diagram introduced by the World Health Organization, three dimensions of coverage are illustrated. Some policy dilemmas are highlighted when attempting to achieve universal health coverage. Finally, various combinations of public and private prepayment schemes are discussed.

This chapter examines how fiduciary principles apply to public offices, focusing on what it means for officeholders to comport themselves to their respective public roles appropriately. Public law institutions can operate in accordance with fiduciary norms even when they are enforced differently from the remedial mechanisms available in private fiduciary law. In the public sector, fiduciary norms are difficult to enforce directly and the fiduciary norms of public office do not overlap completely with the positive law governing public officials. Nevertheless, core fiduciary principles are at the heart of public officeholding, and public officers need to fulfill their fiduciary role obligations. This chapter first considers three areas of U.S. public law whose fiduciary character reinforces the tenet that public office is a public trust: the U.S. Constitution’s “Emoluments Clauses,” administrative law, and the law of judging. It then explores the fiduciary character of public law by looking at the deeper normative structure of public officeholding, placing emphasis on how public officeholders are constrained by the principles of loyalty, care, deliberation, conscientiousness, and robustness. It also compares the policy implications of the fiduciary view of officeholding with those of Dennis Thompson’s view before concluding with an explanation of how the application of fiduciary principles might differ between public and private law settings and how public institutions might be designed or reformed in light of fiduciary norms.

The Impact

Development of tourism affected the socio-cultural environment of many destinations. Previous studies have focused more on analyzing the impact of tourism on all three dimensions of sustainable development (economic, environment and socio-cultural); therefore, the present paper examines tourism development’s impact with regard to the socio-cultural benefits that enhance sustainable tourism development. A survey based on a questionnaire was employed in June 2018 in a mountain village in Cluj County, Romania. The collected data were analyzed using principal component analysis, and several statistical tests were conducted. The results indicated that the respondents have a positive attitude towards tourism development and socio-cultural perceived benefits. Older people and those running a business tend to perceive more positively the benefits of tourism development. The findings of the research could contribute to future development strategies, as it is well known that supporting local communities influences the success of tourism destination.

Objectives: Munich Functional Developmental Diagnosis (MFDD) is a scale for assessing the psychomotor development of children in the first months or years of life. The tool is based on standardized tables of physical development and is used to detect developmental deficits. It consists of eight axes on which the following skills are assessed: crawling, sitting, walking, grasping, perception, speaking, speech understanding, social skills. Methods: The study included 110 children in the first year of life examined with the MFDD by the same physician. The score obtained on a given axis was coded as a negative value (defined in months) below the child’s age-specific developmental level. Next, we examined the dimensionality of the scale and the intercorrelation of its axes using polychoric correlation and principal component analysis. Results: Correlation matrix analysis showed high correlation of MFDD axes 1–4, and MFDD 6–8. The PCA identified three principal components consisting of children’s development in the areas of large and small motor skills (axis 1–4), perception (axis 5), active speech, passive speech and social skills (axis 6–8). The three dimensions obtained together account for 80.27% of the total variance. Conclusions: MFDD is a three-dimensional scale that includes motor development, perception, and social skills and speech. There is potential space for reduction in the number of variables in the scale.

SYNOPSISA questionnaire concerned with dependency, mainly in the mother–child relationship, and intended for use in child psychiatry, is described. It was administered to the mothers of 116 randomly selected junior and secondary school children in the general population, stratified into age, sex, social class, and school groupings. Two meaningful dimensions were revealed by principal component factor analyses: one concerned with reliance on mother and the other reflecting sociability. Reliability and validity were found to be satisfactory.

Brand Associations

Researchers suggest quantification of qualitative data as an innovative approach to knowledge creation. Brand associations, a form of qualitative data, are common in measuring customer-based brand equity. The branding literature suggests that not all brand associations are equal. The strength, uniqueness and valence of brand associations need to be considered when assessing brand associations (Keller 1993). Although Keller's work is cited by many, no study has devised a method to quantify and integrate these three dimensions into a single index. This study provides an approach to address all three dimensions simultaneously. The approach first determines uniqueness of brand associations by coding associations into several mutually exclusive meaning categories. Then the serial order of free-association elicitation is used to assess association strength. The serial order, combined with a measure of valence, creates a quantification of open-ended brand associations called a ‘weighted valence index’ (WVI). In conclusion, the paper discusses the reliability and validity of the proposed measure.
