The aim of the present study was to provide preliminary normative data for ECochG among Asian adults. The influences of ethnicity(Malay versus Chinese) and gender on ECoch G results were also studied.Methods: Twenty-two Malay adults(10 men and 12 women) and twenty Chinese participants(10 men and 10 women) aged between 20 and 49 years participated in this study. Extratympanic ECoch G(ET-ECochG) was recorded according to standard non-invasive procedure. Summating potential(SP) amplitude, action potential(AP) amplitude and SP/AP ratio were analyzed accordingly.Results: ET-ECoch G results were found to be comparable between left and right ears(p > 0.05). No notable differences in ET-ECochG results were found between Malay and Chinese groups(p > 0.05). No significant influence of gender on ET-ECochG outcomes was also noted(p > 0.05). The derived normative data for Asian adults(84 ears) are consistent with previous reports.Conclusion: The present study provides preliminary normative data for ET-ECochG among Asian adults. The ECoch G components do not appear to be influenced by either ethnicity or gender. The derived normative data can be used for clinical applications and as the reference for future studies involving Asian population. 展开更多

Background: Although the standing long jump (SLJ) is a popular physical fitness assessment, it lacks an updated criterion-reference standard. This study generated the first normative SLJ test data for Chinese aged 8 - 18. Methods: From September 2005 to December 2011, comprehensive physical fitness assessments were conducted on 12,712 school students. The SLJ performances were significantly different between boys and girls (all age groups, p < 0.01). Results: The boys performed better than the girls in each age group. The mean difference increased as the age increased, depicting a prominent variance in muscular strength between boys and girls at age 12, and the variances became larger at age 18. Girls in the 70th percenttile performed similarly to boys performing in the 10th percentile. The onset of muscle strength for boys found in this study corresponded to the onset age of testosterone maturation of Chinese boys investigated in previous studies. Linear regression found age and BMI predicting SLJ significantly for boys and girls, explaining better SLJ results in older boy and the effect of their heavy body size. Conclusions: This study indicated a muscular strength difference between genders during growth and added supporting evidence to the hormonal influence of muscle growth during puberty. 展开更多

The purpose of this study is to design a Moroccan Trail Making Test B;explore the effects of age, education and gender on the performance of the Trail Making Test (TMT);and provide normative information in Moroccan subjects. Our normalization study was conducted on 348 subjects (156 female and 192 male). The subjects were classified into four groups based on age (18 - 39 years, 40 - 59 years, 60 - 69 years and ≥70 years), and three groups based on educational level (3 - 6 years, 7 - 10 years and ≥11 years). The data were analyzed using descriptive statistics through SPSS. The results displayed that increasing age and decreasing levels of education significantly result in a decreased performance on the Trail A, Moroccan Trail B and English Trail B. Only 229 bilingual subjects among the 348 initial subjects completed both versions of Trail B. There was no significant difference on performance between Moroccan Trail B and English Trail B for these subjects. 展开更多

Background: Computed Tomography Angiography (CTA) is a new and promising type of imaging to evaluate cardiac structure and function. Although it does require injection of contrast material and some radiation exposure, it is much less invasive than conventional catheter based on angiography. It has been already shown to correlate well with echocardiography images, but normative values have yet to be established. Objectives: To publish the first known data on CTA measurements for all four chambers of the heart. Methods: We conducted a retrospective chart review study of around 3000 patients over a three-year period (2006-2008) from a private cardiology practice in Phoenix, Arizona. Patients were screened for any preexisting conditions that might contribute to abnormal cardiac structures. A “normal” population of 226 patients’ CTA’s was reviewed and 29 different measurements were taken cardiac anatomy. Patients were then categorized based on sex and BMI and the cardiac measurements were compared. Results: The values obtained were similar to already established normal measurement values from echocardiography. There was good correlation between body mass index (BMI) and the sexes. Conclusion: This study serves to establish normative data for cardiac CTA while also proves to show good correlation with already established normative values for echocardiography and justifies these CTA measurements as an alternative means of cardiac evaluation. Further study regarding the variations between data for specific measurements will be addressed in future studies. 展开更多

The aim of this study was to provide normative data of the Moroccan Arabic version of the 10/66 Dementia Research Group cognitive test battery and to explore the effects of age, education/illiteracy, and gender on the performance of these tests. One hundred healthy subjects (67 illiterates and 33 semi-illiterates) participated in this study. None of the participants had serious medical, psychiatric, or neurological disorders including dementia. The protocol included the administration of three components of the 10/66 Dementia Research Group cognitive test battery;Community Screening Instrument for Dementia (CSI “D”, generating the COGSCORE measure of global function), and the Consortium to Establish a Registry for Alzheimer’s Disease (CERAD) verbal fluency (VF), word list memory (WLM, immediate recall) tests. All the test scores were not significantly influenced by sex and age. There was no significant effect of education/illiteracy on the CERAD verbal fluency (VF) and Word List Memory (immediate recall) test scores, but a weakly significant (p < 0.05) effect on the CSI “D” COGSCORE performance. These normative data will be useful for clinical interpretations of the three components of the 10/66 Dementia Research Program protocol in illiterate and semi-illiterate Moroccan subjects with cognitive disorders. 展开更多

The purpose of this descriptive study was to collect quantitative, normative data for the Barnett Balance Assessment-Sitting (BBA-SIT), a newly-developed dynamic sitting balance assessment tool based on the Barnett Balance Assessment (BBA). The BBA-SIT was administered to a total of 180 participants (30 people in each of the following age categories: 18 - 29, 30 - 39, 40 - 49, 50 - 59, 60 - 69, and 70+) who did not have any current balance deficits. A review of normative data collected indicated no variation in the total assessment scores within and between groups. Future research on the BBA-SIT is needed with balance-impaired populations to determine if the BBA-SIT is sensitive enough to identify subtle differences in dynamic sitting balance in individuals with various levels of balance impairment. 展开更多

Objective: We introduce Utena’s Brief Objective Measures of 4 Axes for Psychic Function and Energy (UBOM-4), a new brief test battery for evaluating psychic function concerning intellect, emotion, volition, and imagination. To date, insufficient general population data on the UBOM have been collected. This study aimed to establish the normative values for the general population in UBOM-4 and examine the effects of age, sex, and mental health status on the values. Methods: The General Health Questionnaire, 12-item version (GHQ-12) and UBOM-4 were administered to 149 individuals working in or attending professional schools or universities (73 males, 76 females;age: 19 - 65 years). Participants were classified as healthy based on their GHQ-12 responses and psychiatrist interviews. Results: UBOM-4 measures (mean ± SD) were: pulse rate difference (PRD or UBOM-pulse), &minus;0.72 ± 4.31 beats/min;ruler catching time (RCT or UBOM-ruler), 18.42 ± 3.73 cm;degree of randomness (DOR or UBOM-random), 0.94 ± 0.18;mean randomizing time (MRT or UBOM-time), 0.60 ± 0.31 sec. The Baum Test drawings were classified as usual (86%) and unusual patterns (14%). Sex effects were observed for RCT (UBOM-ruler) and DOR (UBOM-random), but not for PRD (UBOM-pulse) and MRT (UBOM-time). Therefore, the normative values for RCT (UBOM-ruler) (males: 17.37 ± 3.25 cm;females: 19.42 ± 3.90 cm) and DOR (UBOM-random) (males: 0.92 ± 0.18;females: 0.95 ± 0.18) should be differentiated by sex. The patterns of the Baum Test drawings were affected by age, with individuals over 51 years showing the unusual pattern more frequently (42%). Discussion: Compared to previous results for healthy individuals, the present results were similar for RCT (UBOM-ruler), DOR (UBOM-random), MRT (UBOM-time), and the drawing pattern, but different for PRD (UBOM-pulse). This difference is probably because PRD is sensitive to test situation habituation, sex of examiner, order of subtests, etc. Thus, PRD (UBOM-pulse) should be measured after the subject-examiner relationship stabilizes. Conclusion: Our results suggest that UBOM-4 can be widely used in clinical settings, utilizing the present results as a reference. 展开更多

The article concerns the normative value of truth in relation to lie. Based on arguments derived primarily from ancient philosophers (Eubulides, Plato, Aristotle), medieval philosophers (St. Augustine, St. Thomas Aquinas), the thinker of the Renaissance---Machiavelli, the main philosopher of the Enlightenment--Kant, the 19th-century author of Beyond Good and Evil (Nietzsche), and contemporary thinkers such as Derrida and Lacan, the author considers here truth as a normative value. Lying is relative to the truth, and it has no ontological legitimacy, even it cannot exist without truth itself. In the final part of the article, the author concludes that the truth, however, cannot lead to clearly had effects, be harmful or cause pain disproportionate to the effects caused by lie. Therefore, it must coexist with the good--the other parent value. Only when both values complement each other can we talk about the normative value of truth. The truth should be correlated with other values on which value systems are based, especially the good of a person or group of persons, avoiding harm towards others, and the protection of a person's health and life. Only then can the truth be appropriate to use. It is not an immovable foundation, but a dynamically functioning value, in which language and the ethical (active) dimensions provide the value of the specified situations. The truth can be a double-edged sword: It may hurt, but it can defend itself. The latter function seems to be the most important type of the normativity of truth. 展开更多

As the host country of the 26 th United Nations Climate Conference,the United Kingdom(UK)fully carried out climate diplomacy at the conference,and intended to promote the green concept in the international community through diplomatic means,which shows its greater ambition in international climate governance.However,the UK,as the source of the Industrial Revolution,has not always followed the so-called green norms in history.In the interaction with the EU norms after joining the European Community,the UK gradually developed from an"opponent"of green norms to an"advocate"of green norms.After"Brexit",the British government did not stop at the previous green norms of the EU,and further gave the green norms a special brand of the UK on this basis.At present,during the term of Boris Johnson's government,the green norms shaped by the UK have been basically formed and disseminated within a certain mechanism.In this paper,based on the normative power theory and relevant historical facts,how the UK has shaped international norms and obtained normative power through a series of climate policy will be discussed,and some enlightenment to China's participation in the construction of international norms system today will be obtained. 展开更多

This paper conducts analysis on the educational evaluation standard value based on the normative perspective. Systematic evaluation refers to the determination of the nature and state of a system by means of an effective standard, based on the clear system objective, structure, and system properties, and then compares it with a set of evaluation criteria and makes a judgment. The evaluation result is also the interaction of the product. The education evaluation which is constructed with the dialogue thinking is democratic, friendly, open, win-win, and the evaluation of creation. Educational evaluation is not a party to the other party as superior, judgment, conclusion, one-way row order, but both sides of the equality. Under this basis, this paper proposes the educational evaluation standard value based on the normative perspective. In the future, we will apply proposed method into the general applications to verify the effectiveness and systematic effectiveness. 展开更多

Greater attention has been paid to vintage-merge processing of seismic data and extracting more valuable information by the geophysicist. A match filter is used within many important areas such as splicing seismic data, matching seismic data with different ages and sources, 4-D seismic monitoring, and so on. The traditional match filtering method is subject to many restrictions and is usually difficult to overcome the impact of noise. Based on the traditional match filter, we propose the wavelet domain L1 norm optimal matching filter. In this paper, two different types of seismic data are decomposed to the wavelet domain, different detailed effective information is extracted for Ll-norm optimal matching, and ideal results are achieved. Based on the model test, we find that the L1 norm optimal matching filter attenuates the noise and the waveform, amplitude, and phase coherence of result signals are better than the conventional method. The field data test shows that, with our method, the seismic events in the filter results have better continuity which achieves the high precision seismic match requirements. 展开更多
