Effect Of Age

This study intends to validate the Multigenerational Interconnectedness Scale among Arab adolescents. The Arabic version of the scale was administered to 224 male and 294 female Arab students in Grades 10 and 12. Principal factor analysis with a priori three factors and varimax rotation was conducted. This showed good convergence of the items into three subscales: Emotional, Financial, and Functional. Coefficient alpha was .80, indicating good internal consistency. Adolescent girls scored significantly higher on Connectedness to their families than the boys. Given the restricted age range, the effect of age was not significant. Further validation studies are needed with an external criterion for construct validity and a larger sample to cover the older age range of adolescence.

Objectives. To discuss the characteristics of the amount of urinary total antioxidants in tumor diseases and the possibility of utilizing the changing regulation of urinary antioxidants to diagnose tumor diseases.Method. Urine and serum specimens from 130 healthy people were used to investigate the variation of antioxidant capacity against age. Urine and serum specimens from 44 unselected patients with tumors and 44 healthy people with same age background were used to explore the significance of urinary antioxidant capacity in clinic to diagnose tumor diseases. Potassium permanganate agar method and iodine starch method were used to determine the amount of total antioxidants.Results. In healthy people, more antioxidants in urine were measured in older people, while the results were opposite in serum. More antioxidants were found in urine of tumor patients than in healthy people with same age-range.Conclusions. According to the results of 130 measurements, the amount of antioxidants in urine varies by age. By using agar methods to measure antioxidants, the effect of age is required to be considered. Antioxidants levels from tumor patients were significantly higher than healthy individuals in urine. The combination of urine and serum to determine total antioxidants can better diagnose tumor diseases based on iodine starch method, with area under the receiver operating characteristics curve at 0.787.

To establish the psychometric properties of the personality scale in assessed on personality attributes for adult population. Survey type research and correlational design were use. The personality scale was administered on the adult population (N=200, Age group 30-60 years) of Raipur City, Chhattisgarh, India. The psychometric properties of the scale were established by computing Exploratory Factors analysis, reliability (Cronbach’s Alpha) and validity. The result of the exploratory factor analysis in varimax rotation model reveals that 29 items were significantly loaded in three factors out of 30 items. Each items of the scale were highly discriminate. The reliability of personality scale Cronbach’s Alpha is 0.84.The psychometric properties of the personality trigun scale confirm that it is reliable and valid measure of personality attribute (e.g. sat, raj and tam) among adult with age range of 30-60 years.

100 adults, selected for cosmetic dental treatment in a general dental practice, completed a 42-item questionnaire designed, on the basis of previous research and the author's clinical experience, to measure concern for dental appearance. This had high internal consistency and was reduced to a questionnaire of 23 items with internal consistency shown by a standardised Cronbach alpha of .84. An exploratory factor analysis with varimax rotation identified six factors, the main one appearing to be a measure of concern for dental appearance. The high internal consistency suggests that the total score for the revised questionnaire is a measure of a construct, concern for dental appearance. Although the simplest measure of that may be contained in the items for the first factor, a much larger sample would be necessary to confirm the complex factor structure and so the questionnaire's total score is probably the more reliable measure at present. A study is summarised showing that the total score provides a measure that, in statistical regression analysis, may predict the intentions of adults to take care of the appearance of their teeth.

Coffee Brewing

The Specialty Coffee Association Brewing Control chart has been used for the past 50 years, and is intended to assist the coffee brewer by stating the brew ratio and TDS (total dissolved solids) value needed to brew an “ideal” cup of coffee. Since coffee is a common and popular beverage that is consumed among populations ranging from children to elders, the objective of this study was to find out whether taste preferences in coffee vary based on age and whether these preferences match the current brewing control chart standard. Data collected in this study was based on a taste test with 32 total participants selected randomly. Of these participants, 10 fell into the 10-19 years old age range, 5 in the 20-29 range, 4 in the 30-39 range, 7 in the 40-49 range, and 6 in the 50-59 range. Based on the data from these respondents, no obvious trend between age range and coffee preference was observed; but, this is subject to change with larger sample sizes.Overall taste preferences, however, do generally fit the current standard ideal range on the coffee brewing control chart.

By setting out from similar studies, this study falls within international literature. The intention is to measure, in connection with Turkey’s consumer market, in order to understand the behaviors of the Turkish consumers that are different in terms of cultural variables. The operability of this international theory is achieved by taking advantage of mental accounting. In seeking the essential objective of the research, a working group formed from two subgroups in order to manifest the decisiveness in the purchasing decisions of individuals, as well as the effects of the mental accounting theories. The first subgroup is formed by 100 university students whose ages are varied between 18 and 30. The second group forms from the same number of students at the same age range. According to the results of analysis carried out in the direction of the collected data from the sub groups, the consequences of this study support the results of the other a priori study in the literature. The greatest consequence of this research is the reactions developed in the expenditures and savings of the consumers subsequent to the formed sunk costs become varied with in terms of the independent “budget” variable.

Background: Experiences that a child or adolescent goes through play a critical role in their development as an individual. To understand the world of adolescents and their mental health and well-being, it would be important to be able to access their experiences. Therefore, an objective measure to assess experiences is necessary. The study aimed to develop a scale to assess experiences and establish their psychometric properties. Materials and methods: My Experiences Scale (MES) is a newly developed 50-item, multiple-choice, self-report measure. Various steps involved in developing the MES and establishing its psychometric properties have been elaborated. The study was carried out across four phases, and the sample consisted of 1,260 school-going children and adolescents. The participants were representative of both genders, a wide age range, and diverse socioeconomic backgrounds. Results: MES was found to have good internal consistency (Alpha 0.85) and test–retest reliability (0.96). MES was found to have significant correlations with Strengths and Difficulties Questionnaire and global self-worth. Conclusions: The newly developed experiences scale shows promising psychometric properties and a wide scope for application.

Effect Of Age

The association between the age of a horse and their capacity for learning is understudied despite the large age range of horses used for both competition and leisure purposes in the UK and the considerable number of horses that swap over between different disciplines; for instance 4000 racehorse retire from racing each year and many go on to other careers including 900 each year going on to be polo ponies. A negative correlation between age and learning performance has been reported in test species to-date (Yagi et al., 1988); however relatively few studies have addressed this issue in equines (Madder & Price, 1980; Williams et al., 2004). The aim of the present study therefore was to investigate the association between a horse’s age and gender and the time taken to reach a pre-determined criterion during an operant learning task.

Children’s disclosures of sexual abuse during forensic interviews are fundamental to the investigation of cases. Research examining the relationship between age and disclosure has shown mixed results; the aim of the current study was to clarify and extend our knowledge by modeling linear, quadratic, and interaction effects of age on disclosure. Child sexual abuse reports made by children, their caregivers, or mandated reporters over a 12-month period to police in one state of Australia were examined. Of the 527 children (age range 3–16 years) offered a forensic interview, 81% disclosed abuse during it. The other 19% did not disclose or refused the interview. Age had both linear and quadratic effects, whereby disclosure increased with age until 11 years, after which disclosure decreased with age to 16 years. The effect of age on disclosure was moderated by five variables: abuse severity, the child–suspect relationship, suspects’ violence histories, delay of report to police, and children’s previous disclosures. Particular groups of children had lower likelihoods of disclosing abuse in forensic interviews than others, such as adolescents who alleged abuse against suspects with histories of violent offending. By identifying these groups, targeted strategies may be developed to help increase their disclosure rates.

IntroductionThe Hewitt and Flett Multidimensional Perfectionism Scale (H&F-MPS) is one of the most used measures of perfectionism. Their 45-items evaluate self-Oriented (SOP), Self-Prescribed (SPP), and Other Oriented (OOP) perfectionism.ObjectivesTo study the internal consistency and convergent validity of the H&F-MSP13.MethodsOne hundred and ninety-two university students (78.1% females), aged 19.74 years (sd = 2.10; range: 17–28) completed the Portuguese versions of H&F-MPS (Soares et al., 2003) and of Frost et al. MPS (F-MPS) (Amaral et al., 2013). Thirteen items were selected from the Portuguese version of the H&F-MPS, based on their loading in the factor (0.60 and over) (Soares et al., 2003).ResultsThe H&FMPS13 revealed good internal consistency (α = 0.816). The corrected item-total subscale Spearman's correlations were high (from 0.418 to 0.820). The principal component analysis with factors varimax rotation produced three factors, which revealed acceptable/good internal consistency (SOP: explained variance/EV = 35.4%, α = .900; SPP: EV = 16.3%, α = 0.695; OOP: EV = 10.8%, α = 0.709). The correlations between the H&F-MSP13 scores and the matching scores of the H&F-MPS were high (from r = 0.745 to r = 0.945, all P < .01), suggesting that both scales measure similarly the constructs. The H&F-MSP13 and the H&F-MPS total scores demonstrate good convergent validity with the total score of F-MPS, as indicated by the correlations (r = 0.581/r = 0.636, respectively). The correlations similarities between the H&F-MSP13 and H&F-MSP dimensions and the F-MPS dimensions and total scores were also considerable.ConclusionsThe H&F-MSP13 is a valid instrument to measure perfectionism that reveals convergent validity with the F-MPS, retaining the adequate psychometric properties of the H&F-MPS and its administration is less time consuming.Disclosure of interestThe authors have not supplied their declaration of competing interest.

Aim of this research was to identify and analyse relative age effect (RAE) on sample composed of young Croatian taekwondo competitors. In order with aim of research, for medal winners (n1=72) and other competitors (n2=187) who competed at Croatian taekwondo cadet championship 2015, date of birth, weight category and sport success were extracted. By conducting of Chi-square test on all competitors (n=259) it is proven there is non-significant difference (χ2=12.28; p=0.34) between expected and observed frequencies according to month of birth. Furthermore, significant difference between observed and expected frequencies according to year of birth of medal winners (χ2=45.31; p<0.01) is confirmed. Results of this research are pointing on presence of RAE which could lead to mistakes in selection of young athletes. Authors are suggesting to minimize allowed age range for competition, or to separate competitors in more age categories, which would enable more equal competitions and reduce effect of age on sport success.
