The Symbiosis of Sacred Space and Secular Experience-Reflecting on Ethnographic Filming

Based on the experience of ethnographic filming,this article outlines the dynamic process of the protection and development of Baima Tibetan traditional villages with the help of iconic descriptions of Baima Tibetans’daily lives and sacrificial activities,and explores how Baima Tibetans inherit their culture while adapting to social development with imagery means during rural revitalization,and how the locals integrate sacred space and secular experience in order to construct their own cultural symbols for the sake of embracing the new era.As far as anthropology-ethnographic descriptions of embodiment are concerned,traditional text research has limitations.In comparison,video graphic anthropology has natural advantages.Its advantages not only lie in the means of images,but also lie in the ability to connect the“sense of things”,mind and nature,realizing the interaction between mind and things,and mentality and object.The visual ethnography is an important research method for anthropological research to enter the world of his other.This is also an important way to describe the integration and symbiosis of local subjectivity,local sacred space,and secular experience.

Secular Change in Stature of Urban Chinese Children and Adolescents, 1985-2010

Objective Research evidence shows a secular trend in Chinese physical growth in recent years.The aim of this study was to analyze and assess changes in stature of children and adolescents during the 25 years from 1985‐2010,using national data.Methods Data came from successive cycles of the Chinese National Survey on Students＇ Constitution and Health（CNSSCH）.Subjects were 7‐ to 18‐year‐old children and adolescents.Results An overall positive secular trend occurred in urban China during 1985‐2010.The overall average rates of increment were 2.4 and 1.7 cm/decade for boys and girls,respectively.Total increases in adult stature for boys and girls were 2.6 and 1.7 cm,yielding rates of 1.0 and 0.7 cm/decade,respectively.Cities with different socioeconomic levels had different characteristic trends.Mean stature increases in big cities were larger than those in moderate and small cities,and boys and girls in moderate and small cities showed greater potential for growth in stature.Conclusion An overall positive secular growth trend was associated with socioeconomic progress and differed with area socioeconomic levels.School policies and strategies should be developed based on increased stature,and should continue narrowing the inequity between different socioeconomic populations.

Secular Changes of Stature in Rural Children and Adolescents in China, 1985-2010

Objective To analyze and assess secular change in stature in rural children and adolescents in China from 1985 to 2010. Methods Data were obtained from the 6 rounds of the Chinese National Survey on Student＇s Constitution and Health. The subjects enrolled in the study were children and adolescents aged 7-18 years in rural areas of provincial capitals. Results An overall positive secular trend in stature occurred in rural areas of provincial capitals in China from 1985 to 2010. The overall average increase rates were 3.1 and 2.4 cm/decade for boys and girls, respectively. The total body height increases for grown up boys and girls were 3.6 and 2.3 cm and the increase rates were 1.4 and 0.9 cm/decade, respectively. There were differences in body height increase among eastern, central and western regions. The average body height of the children or adolescents in eastern region was highest, followed by central region and western region. The overall increase rates in central region were highest among the three regions. The difference between eastern/central region and western region was obvious. 〈br〉 Conclusion Positive secular trend in stature of children or adolescents has occurred in rural area of China, and rural boys and girls showed a great potential for continuous growth. More attention should be paid to the differences in children＇s body height between western region and eastern/central region.

Secular Changes on the Distribution of Body Mass Index among Chinese Children and Adolescents, 1985-2010

Objective To analyze the change in Body Mass Index （BMI） distribution among Chinese children and adolescents for the development of more effective intervention for childhood obesity. Methods Data on the national students＇ constitution and health survey between 1985 and 2010 was used for this study. Subjects were students aged 7-18 randomly selected from 30 provinces in China. BMI for-age curves were developed by LMS method, and the trend of BMI distribution was determined by comparing the upper BMI percentiles and analyzing the skew shift of distribution between 2985 and 2010. Results An overall positive swift trend of BMI between 1985 and 2010 was observed among the Chinese school-age children and adolescents. The average median of the BMI increased from 16.8 and 17.0 ks/m2 to 18.2 and 17.9 kg/m2 in 25 years, with increments 0.56 and 0.36 kg/m2 per decade for males and females, respectively. The more obvious increments were found at the high BMI. The total increments of BMI in this period were 4.03 and 2.20 kg/m2 at the 85th, 6.24 and 3.57 kg/m2 at the 95th, and 6.99 and 4.27 kg/m2 at the 97th percentiles, for males and females, respectively. Conclusion Obvious increments were observed at high BMI of the Chinese children and adolescents. More effective interventions should be taken for control and prevention of obesity and its health consequence for these subgroups. It is necessary to establish a risk-complex system consisting of the identification of BMI scope, the screen of the disease risk factors and the assessment of excessive adiposity.

Secular trends in incidence of lung cancer by histological type in Beijing, China, 2000-2016

Objective: The objective of this study was to characterize secular trends in the sex-specific, age-standardized incidence of lung cancer by histological type in Beijing, China, from 2000 to 2016 based on data from a populationbased cancer registry.Methods: Data on the incidence of cancer from 2000 to 2016 were obtained from the Beijing Cancer Registry.We examined trends in the sex-specific, age-standardized incidence of lung cancer by histological type using a Joinpoint regression model.Results: A total of 117,409 cases of lung cancer were diagnosed from 2000 to 2016. Overall, 73,062(62.23%)patients were males. The most common histological type among both sexes was adenocarcinoma; however, the proportion of adenocarcinoma differed significantly between males and females(45.36% vs. 77.14%, respectively,P<0.0001). The age-standardized incidence of total lung cancer increased from 2000 to 2010 with an annual percent change(APC) of 2.2% [95% confidence interval(95% CI), 1.5% to 2.9%] and stabilized thereafter. Among males, the incidence of total lung cancer peaked in 2008 and then decreased slightly, with an APC of-1.1%(95%CI,-2.1% to-0.1%). Among females, the incidence increased continuously during the study period, with an APC of 1.4%(95% CI, 0.9% to 1.9%). The incidence of squamous cell carcinoma decreased significantly in recent years among both sexes, with APCs of-2.6%(95% CI,-4.5% to-0.6%) from 2007 to 2016 for males and-5.4%(95%CI,-7.2% to-3.6%) from 2004 to 2016 for females. In contrast, the incidence of adenocarcinoma increased continuously throughout the study period, by APCs of 4.0%(95% CI, 2.6% to 5.4%) for males and 6.2%(95% CI,4.8% to 7.6%) for females. The incidence of small cell carcinoma peaked in 2007 and stabilized thereafter among males, whereas it peaked in 2012 and then decreased with an APC of-14.7%(95% CI,-25.3% to-2.6%) among females. The incidence of large cell carcinoma and other specified malignant neoplasm did not change much,whereas the incidence of unspecified type decreased among both sexes during the study period.Conclusions: Although the incidence of squamous cell carcinoma decreased significantly among both sexes in recent years in Beijing, China, adenocarcinoma increased continuously throughout the study period among both sexes. Knowledge of differences in trends is useful for surveillance and control of lung cancer. However, the reason for the increase in adenocarcinoma remains unclear and warrants investigation.

On the correlation of nonlinear variables containing secular trend variations： numerical experiments

Due to global warming, the general circulation, underlying surfaces characteristics, and geophysical and meteorological elements all show evident secular trends. This paper points out that when calculating the correlation of two variables containing their own obvious secular trends, the interannual correlation characteristics between the two variables may be distorted （overestimated or underestimated）. Numerical experiments in this paper show that if two variables have opposite secular trends, the correlation coefficient between the two variables is reduced （the positive correlation is underestimated, or the negative correlation is overestimated）; and if the two variables have the same sign of secular trends, the correlation coefficient between the two variables is increased （the positive correlation is overestimated, or the negative correlation is underestimated）. Numerical experiments also suggest that the effect of secular trends on the interannual correlation of the two variables is interchangeable, that is to say, as long as the values of the two trends are not changed, the two variables interchange their positions, and the effect of the secular trends on the interannual correlation coefficient of the two variables remains the same. If the two variables have the same-（opposite-） sign trends, the effect of secular trends on the interannal correlation coefficient is more （less） distinctive. A meteorological example is given.

Exploring the metamorphic consequences of secular change in the siliciclastic compositions of continental margins

Shale and greywacke compositions from the Archean to Phanerozoic record a secular change in the siliciclastic material that comprises much of Earth＇s continental margins, past and present. This study explores the metamorphic consequence of these compositional changes, by comparing phase equilibrium models constructed for average Archean, Proterozoic, and Phanerozoic shale and greywacke compositions equilibrated along two Barrovian-type geotherms： 1330℃/GPa（A） and 800 ℃/GPa（B）. Our models show that Archean siliciclastic rocks can retain up to 4 vol.% water at middle to lower crustal conditions, nearly twice that of Proterozoic and Phanerozoic compositions. The increased ferromagnesium content of Archean siliciclastic rocks stabilizes chlorite to higher temperatures and results in a biotite-rich assemblage at solidus temperatures. Accordingly, water-absent biotite dehydration melting is predicted to play a greater role in the generation of melt in the metamorphism of Archean aged units,and water-absent muscovite dehydration melting is of increasing importance through the Proterozoic and Phanerozoic. This secular variation in predicted mineral assemblages demonstrates the care with which metamorphic facies diagrams should be applied to Archean compositions. Moreover, secular changes in the composition of shale and greywacke is reflected in the evolution of anatectic melt towards an increasingly less viscous, Ca-rich, and Mg-poor monzogranite.

The Influence of Secular Trends in Body Height and Weight on the Prevalence of Overweight and Obesity among Chinese Children and Adolescents

Objective To explore the influence of secular trends in body height and weight on the prevalence of overweight and obesity among Chinese children and adolescents. Methods The data were obtained from five cross-sectional Chinese National Surveys on Students＇ Constitution and Health. Overweight/obesity was defined as BMI-for-age Z-score of per the Wold Health Organization （WHO） reference values. Body height and weight for each sex and age were standardized to those reported in 1985 （standardized height＂ SHY, standardized weight： SWY） and for each sex and year at age 7 （standardized height： SHA; standardized weight： SWA） using the Z-score method. Results The prevalence of overweight/obesity in Chinese children was 20.2% among boys and 10.7% among girls in 2010 and increased continuously from 1985 to 2010. Among boys and girls of normal weight, SHY and SHA were significantly greater than SWY and SWA, respectively （P 〈 0.001）. Among boys and girls with overweight/obesity, SHY was significantly lower than SWY （P 〈 0.001）, and showed an obvious decreasing trend after age 12. SHA was lower than SWA among overweight boys aged 7-8 years and girls aged 7-9 years. SHY/SHW and SHA/SWA among normal-weight groups were greater than among overweight and obese groups （P 〈 0.001）. Conclusion The continuous increase in the prevalence of overweight/obesity among Chinese children may be related to a rapid increase in body weight before age 9 and lack of secular increase in body height after age 12.

Secular trends of intrahepatic cholangiocarcinoma in a high endemic area:A population-based study

BACKGROUND Intrahepatic cholangiocarcinoma(ICC)is one of the most aggressive malignancies.However,because of its scarcity there are limited population-based data available for investigations into its epidemiologic characteristics.In Taiwan,we have a national cancer registry database that can be used to evaluate the secular trends of ICC.AIM To evaluate secular trends of ICC according to age,sex,and risk factors in Taiwan.METHODS In this population-based study,we used the national Taiwan Cancer Registry database.Age-standardized and relative percent changes in incidence rates were used to describe secular trends in incidence rates and sex ratios of ICC in Taiwan.RESULTS The age-standardized ICC incidence rate among males increased from 1.51 per 100000 in 1993-1997 to 4.07 per 100000 in 2013-2017 and among female from 1.73 per 100000 to 2.95 per 100000.The incidence in females tended to plateau after 2008-2012.For males,the ICC incidence increased as age increased.In the long-term incidence trend of ICC in females,the incidence of the four age groups(40-44,45-49,50-54 and 55-59 years)remained stable in different years;although,the incidence of the 60-64 group had a peak in 2003-2007,and the peak incidence of the 65-69 and 70-74 groups occurred in 2008-2012.Among males,beginning at the age of 65,there were increases in the incidence of ICC for the period of 2003-2017 as compared with females in the period of 2003-2017.CONCLUSION Increased incidence of ICC occurred in Taiwan over the past two decades.The increased incidence has progressively shifted toward younger people for both males and females.

The Secular Tendency of the Age at Menarche in a Representative Sample of Mexican Girls from an Urban Zone in Central Mexico

Objective: To investigate the age at menarche, pubarche and telarche in a representative sample of residents of an urban zone of Leon, Guanajuato, Central Mexico and to evaluate the secular change of the age at menarche between 1985 and 2000. Methods: Using status quo and retrospective methods, menarcheal, pubarcheal and telarcheal status of girls 8 - 17 years of age (n = 1093) were determined. Multiple regression analysis and logistic regression were used to determine factors that were related to or predictive of age at menarche. Results: Median ages for menarche, pubarche and telarche in our studied sample were: 11.9 ± 0.04;11.13 ± 1.25 and 10.84 ± 1.34 years, respectively. A direct correlation was found between the age of menarche of adolescents and that of their mother (p p p = 0.001), but an indirect correlation was found with the girls’ hip circumference (p = 0.004). We demonstrated a clear secular tendency towards an earlier onset of menarche by comparing our results (11.9 ± 0.04) with data from 1985 (12.8 ± 1.3) for adolescents from the same city. Conclusion: We demonstrated a clear reduction in age at menarche of approximately 0.75 year/decade, higher than Tanner’s finding in 1962, but similar than that of Malina et al. in 2004.

The Rise and Fall of the Secular Trend in Body Height in Sardinia:An Age-Period-Cohort Analysis

Objective Over the last century, a progressive rise in stature, known as the ‘secular trend’, was documented worldwide, and especially in Sardinia, it has reached a peak in Europe. However, this situation recently ceased in several populations. In this study, we tested the hypothesis that the stature secular trend has significantly leveled off in the Sardinian younger generations.Methods Height measurements were retrieved from a database of patients undergoing digestive endoscopy, spanning generations between 1920 and 1990. Sex-specific principal component regression models were fitted to decompose stature variation into the contribution of age, period, and birth cohort.Results A steady increase in stature was observed in generations born after 1920, with an upward surge in those born after 1950. However, a significant leveling off was observed among cohorts born after 1970 among both sexes, as mean heights stabilized at 171.1 cm with a standard error(SE) of 0.9 cm among men and a mean of 160.1 cm(SE = 0.9 cm) among women.Conclusion Our findings support a significant slowdown in the secular trend of stature among the latest Sardinian generations. Several factors, including the consumption of low-quality food, lack of physical activity, and late motherhood, among others, may explain the decline in the secular trend.

Secular evolution of continental crust: recorded from massif-type charnockites of Eastern Ghats belt, India

It is reasonably well established that the Earth has substantially cooled from the Archean to the pre-sent and hence the sites, rates and pro- cesses of crust formation must have changed through geo-logic time. Archean and Proterozoic granitic rocks are the principal record of such changes. Massif-type charnockites in the Eastern Ghats granulite belt, India, of Archean and Proterozoic ages mirror the changing conditions and/or processes of continental crust for- mation. Though both can be explained by dehydration melting of mafic rocks, the conditions differ. Potasium and rubidium rich Proterozoic charnockites have significant negative Eu ano- maly indicating melting at shallow depths in the stability field of plagioclase. In contrast, sodium and strontium rich Archean charnockites with less LREE enrichment and less depletion in Eu indicate melting at greater depths in the stability field of garnet or amphibole.

Secular change in earth processes： Preface

1.Introduction Uniformitarianism is a traditional approach used in many areas of geoscience that assumes the geologic processes observed today operated similarly throughout all of Earth history（Hutton,1788;Windley,1993）,with such an ideology commonly encapsulated by the maxim＂the present is the key to the past＂.This concept is closely associated with the philosophical principle of Occam’s razor.

Mafic Dyke Swarms: Their Temporality and Bearing on the Secular Evolution of the Earth

Pioneering U-Pb isotopic studies by a small group of workers in the mid-late 1980s demonstrated the feasibility of using rare accessory mineral chronometers in mafic(gabbroic)intrusive rocks.These examples showed that mafic layered intrusions and diabase/dolerite dyke swarms alike crystallized high-temperature

An Investigation of the Secular Acceleration of Psychiatric Disorders

Secular acceleration, for example an increase in height in groups of people over a period of time of more than a century, is a unique, perhaps “ecological” event. In the study presented here, historical patient files from the Jena Psychiatric Clinic were evaluated in relation to the problem of acceleration. A first sampling of 119 patient files for the years 1880-1890 revealed that, for children and adolescents up until the end of their twentieth year of life, the average age at the time of their first admission was 17 years. Compared to this, the first admission of a second sample of 132 patient records for the years 1985-1987 revealed a clearly younger average age at first admission of 11 years. This difference in age was found to be statistically significant. The heights of 14-year-old subjects from the city of Jena for the years 1880 to 1975 obtained from the literature showed a documented increase in height of almost 20 cm. The results of our investigation revealed that, in addition to physical acceleration, there was also an advancement of pathological mental processes in the course of a period of 100 years.

Neoteric Nationalism in India: Secular or Religious?

The nationalism in India emerged with the national movement as an urge of political independence,but it is not necessarily a derivative of nationalism.In this post-independence period,the concept took a drastic change from politico-cultural nationalism to particularistic nationalism of many groups and now essentially religious nationalism.The present blend of nationalism is interpreted as Hindu nationalism.It evolved from nationhood to nationalism.In this open world,Indian nationalism has been unrolled with a Hindu dominating policy due to which religion in India got politicized.The surge of religion is too high in India has become an important political agenda.It has shuttered the participation of the religious minority from the mainstream of politics.This paper is an endeavour to present this new discourse of Indian nationalism which emerged at the backdrop ofHinduism.

A Comparative Study on the Buddhist and Brahmanic Conceptions of the Relationship between the Secular World and the Emancipation Realm

Buddhism and Brahmanism were two important religions in ancient India and their religious philosophies continue to be the fundamental components of contemporary Indian culture. However, these religions share common theoretical problems like explanation of the relationship between the secular world and the emancipation realm. This article examines this issue.

Secular trend analysis of lung cancer incidence in Sihui city,China between 1987 and 2011

Background:With industrial and economic development in recent decades in South China,cancer incidence may have changed due to the changing lifestyle and environment.However,the trends of lung cancer and the roles of smoking and other environmental risk factors in the development of lung cancer in rural areas of South China remain unclear.The purpose of this study was to explore the lung cancer incidence trends and the possible causes of these trends.Methods:Joinpoint regression analysis and the age-period-cohort(APC) model were used to analyze the lung cancer incidence trends in Sihui,Guangdong province,China between 1987 and 2011,and explore the possible causes of these trends.Results:A total of 2,397 lung cancer patients were involved in this study.A 3-fold increase in the incidence of lung cancer in both sexes was observed over the 25-year period.Joinpoint regression analysis showed that while the incidence continued to increase steadily in females during the entire period,a sharp acceleration was observed in males starting in 2005.The full APC model was selected to describe age,period,and birth cohort effects on lung cancer incidence trends in Sihui.The age cohorts in both sexes showed a continuously significant increase in the relative risk(RR)of lung cancer,with a peak in the eldest age group(80-84 years).The RR of lung cancer showed a fluctuating curve in both sexes.The birth cohorts identified an increased trend in both males and females;however,males had a plateau in the youngest cohorts who were born during 1955-1969.Conclusions:Increasing trends of the incidence of lung cancer in Sihui were dominated by the effects of age and birth cohorts.Social aging,smoking,and environmental changes may play important roles in such trends.
