Rate efficient estimation of realized Laplace transform of volatility with microstructure noise

In this paper, we consider the problem of estimating the Laplace transform of volatility within a fixed time interval [0,T] using high‐frequency sampling, where we assume that the discretized observations of the latent process are contaminated by microstructure noise. We use the pre‐averaging approach to deal with the effect of microstructure noise. Under the high‐frequency scenario, we obtain a consistent estimator whose convergence rate is , which is known as the optimal convergence rate of the estimation of integrated volatility functionals under the presence of microstructure noise. The related central limit theorem is established. The simulation studies justify the finite‐sample performance of the proposed estimator.

从“轻武”与“尚武”看中日两国传统文化的差异

近代以前,中日两国的封建统治阶级的性格不同,中国的统治者是文人,以“文”人仕立朝,以儒学作为封建统治的道德基础;日本的统治者是武士,以“武”扬名人仕,以武士道作为封建统治的道德基础。因此,“轻武”与“尚武”成为中日两国在传统文化上的一个重要差异。     

韩国全罗南道岁时风俗研究

Seasonal customs, also called“performances that take place within a one year cycle”, refer to a series of customs, patterns or norms practiced periodically and habitually on spe-cific days within the regular cycle of the four sea-sons. Seasonal customs are found in every month, such as the Spring Festival in the first month, Laborers’ Day in the second month, The 3rd day in the third month, the birthday of Sakyamuni in the fourth month, the Dano Festival in the fifth month, etc. ( all dates mentioned in this paper are in the lunar calendar) . As the years go by, the seasonal customs change constantly. Many of them have been faded as society has changed, and they have been replaced by National Holidays or other legal holidays which regulate people’s lives. In addition, as western and other cultures filter in, holidays like Valentine’s Day, and Christmas have stepped into people’s lives. Because these festivals are no longer linked with traditional religious meanings found in the old customs, and place more emphasis on entertainment, they have been accepted almost instantly, taking up social space, and changing people’s activities and behaviors. Apart from these, festivals in some particular areas became popular and spread nationwide as the result of na-tional policies. As an important constituent, seasonal customs can reveal the cultural state and spiritual world of a country or region. Jeollanam-do in South Korea, known as the treasure house of customs, possesses rich customs and heritage and various annual cus-toms can be seen here. This paper, by making a general investigation of the customs in Jeollanam-do, can help us further understand the state of this region’s history and ideology, and the cultural im-plications hidden within it. In the first month of the lunar calendar, the primary festivals are the Spring Festival, the First Day of the First Lunar Month, and the Fifteenth Day of the First Lunar Month. 1 ) In the Spring Festival, the most important activities are offering sacrifices to gods and ancestors, sweeping tombs, and paying New Year’s visits. People also believe that this is the proper time to avoid the“three dis-asters”, keep away night ghosts, burn hair, and go to fortune tellers, etc. There are also games played in this period, such as the see-saw and board-turning. 2) the First Day of the First Lunar Month cannot be counted as a traditional festival. However, a day’s rest is taken in the countryside when every house sticks spring couplets on their doors or pillars. These are pairs of long strips of paper on which auspicious words or sayings are written. 3 ) In traditional society, when farming dominated, people observed the Fifteenth Day of the First Lunar Month with grand ceremony, main-ly through engaging in entertaining activities. In Jeollanam-do, the festival atmosphere is warmly created by playing folk or peasant music, flying kites, playing tug-of-war games, or Gohssaum, and so on. In addition to the group activities, indi-vidual families might offer sacrifices in their hou-ses. Each village also offers sacrifices together, known as the Tangshan Sacrifice and Dragon King Sacrifice. There are various superstitions related to this day. For example, many people will buy a strainer and hang it at home, believing that it will bring blessings. Or, on the eve of this day people might set fires on field ridges, believing that this will bring a good harvest. People might also set up Changsheng or Changganzi, along the borders or milestones separating villages from each other, which are known as the patron gods protecting their territory. On this day the staple food is supposed to be“Wugufan”, literally“Rice with Five Grains”, which actually includes more than five kinds of va-rious grains. It is so-called because all the main grains are collectively called “five grains”. In ad-dition, people also cook the“Eight Treasures Rice Soup” which contains glutinous rice, Chinese dates, chestnut, honey, pine nuts, an beans, etc. In the second lunar month, there are the Laborers’ Day and the Yongdung Festival. On the 1st of the second month, Laborers’ Day, laborers used to be given a day’s rest when people made a kind of dessert known as “Agecake”. However, because no one hires laborers nowadays, this cus-tom has actually disappeared. It is said that on 1st day of the second month, Yongdung Halmoni de-scends from the sky, and returns there on the 15th or 20th day. Yongdung Halmoni is said to be the goddess in charge of wind, so, in fishing areas where wind matters a lot, people will offer sacri-fices to her. It is said that if Yongdung Halmoni descends with her daughter-in-law, the wind throughout the whole year will be too strong to guarantee a good harvest, but good sailings can be counted on if she descends with her daughter. On the 3rd day of the third month, women in Jeollanam-do bring simple cooking equipment to the riverside, and pass a pleasant day there. They mix glutinous rice powder with rhododendron petals to make pancakes which they call “flower pan-cakes”. While they eat, they sing songs about flower pancakes or other folk songs. Around 3 rd day of the third month, butterflies start to appear and “dance”. It is believed that if yellow butter-flies are seen first, the coming year will be smooth, but if white butterflies are seen first, there will be many funerals or other inauspicious things. On the 8 th day of the fourth month the birthday of Sakyamuni, many people go to the temples and hang Buddhist lanterns. The display of lanterns on that day is truly grand. It is attended mainly by women who pray for happiness, safety, good health, success and prosperity for their family members. In the temples, people perform the ritu-al of“circumambulating the stupas”, spending the entire night sleepless walking around the stupas, praising gods’ merits and credits, and repeating their wishes in their hearts. While circling the stu-pas, people usually listen to Buddhist chants,some places may play the traditional music with tradi-fional instrument. On the 5th day of the fifth month, on the Dano Festival, the following activities are found in Jeol-lanam-do. 1 ) wrestling, a competitive game played mainly by males; 2 ) swinging, played mainly by females; 3 ) washing hair with acorus calamus. It is believed that hair becomes smooth and shiny if washed with water boiled with acorus calamus. Therefore, many women wash their hair in this way on the 5th day of the fifth month. 4) imbibing herbal medicine. During the Dano Festi-val, all things on the earth are said to be suitable for medicine. There are drinkable herbal juices made from Leonurus heterophyllus, or Ay Tsao. People pluck all kinds of herbs and dry them for future use. The 15 th day of the sixth lunar month is Yudu Day. It is believed that if you wash your hair with clear stream water on this day, bad luck is kept a-way and you will not suffer heatstroke in summer. According to local folklore, the Dragon God and God of the field ditches check on the crops on this day, so no fieldwork is allowed, and a day’s rest is required. If people insist on going to work, it is said they will not have a good harvest. Rice cakes are also prepared on this day and placed in the crop fields as simple offerings to the Dragon God for a good harvest. In June, which has the hottest days in the year, the month is divided into the ini-tial, middle and final hottest days. In order to build up their health, people cook delicious gin-seng chicken soup by putting ginseng, jujubes and glutinous rice into the chicken’s abdomen. Or, for the sake of vitality, some men may drink a body-protecting soup, the so-called dog meat soup. The 7 th day of the seventh month is the Chilseok Festival. Since Chilseok is closely con-nected with the Chilseok God, every family will pray to the Chilseok God for blessings, or go to temples to offer sacrifices. In this festival some families may offer sacrifices to Chengzhu God as in other festivals, but not many offerings are required except for some rice and vegetable dishes. On the 15th day, the Baekjung Day, all kinds of fortune-telling activities prevail. All fieldwork stops and a day’s rest is taken. On this day people also prepare food to offer to the ancestors. The 15th day of the eight month, the Mid-Au-tumn Festival, is characterized by harvest and thanks-giving. Various activities can be seen in Je-ollanam-do, among which offering sacrifices and sweeping tombs are given priority, even more than during the Spring Festival. During the mid-autumn days everyone, rich or poor, makes Songbing, which is very much like a Chinese moon cake, and it is still the most representative festival food for the Mid-Autumn Festival Day. After finishing mak-ing the Songbing with newly harvested rice, people will carry them together with many fruits to offer sacrifices in the early morning and sweep tombs. Some people may go to the cemetery to pull weeds before sweeping tombs. At night, during the full moon, in order to liven up atmosphere, women will perform traditional dance . There is also a custom observed on the Mid-autumn day—married daugh-ters will meet with their own parents and relatives in a place located mid-way between the two homes. Sometimes, female neighbors may agree to meet with each other at a certain appointed place and bring food along to spend a pleasant day to-gether. The 9 th day of the ninth month is the Jungu Festival. It is no longer regarded as a particular festival, but it is still considered a lucky day. In the past, on this day, people would make wine, rice cakes and even medicine, out of chrysanthe-mums. Moreover, literati would appreciate poems as well as maple leaves, which were quite scenic. There are no special festivals during the 10 th lunar month, though this is considered a lucky month because many things forbidden in other months are permissible during this month. The 15th day is a day for some families to offer sacrifices to ancestors or drive away disasters. In rural areas, one of the family customs is for women to bathe and change their clothes before replacing the old rice in ancestor pot with newly harvested rice. This is re-garded as a recommended ritual to domestic gods of new rice. In the 11th lunar month, at the winter sol-stice, it is customary to have red bean soup, which is cooked with glutinous rice powder and red beans mixed together. Its red color is believed to protect people against evil spirits. People offer the red bean soup to their ancestors, and, splash it in front of doors, on walls, around the kitchen, and in their yards. This is all done in order to keep ghosts outside. The 30th day of the 12th month, New Year’s Eve, is the time to stay up late to see in the New Year. So, every house has lights on overnight. It is customary to visit elderly people and inquire a-bout their physical condition and to show care on this eve. This is called “paying an old year’s call”. In olden times, snow which fell in the 12 th month was put into bottles, and when the snow melted the water was believed to be a good medi-cine for curing heatstroke in summer. To sum up, seasonal customs in Jeollanam-do are multi-functional, including the following five aspects:1 ) worshipping the ancestors;2 ) praying for a good harvest and good fishing;3 ) keeping a-way bad luck and calling for blessings;4 ) sharing happiness and improving harmony;5 ) hygiene and health care. Folk customs in Jeollanam-do are diversified. While taken as the concrete outward representa-tions of seasonal customs, these folk scenarios car-ry distinctive features of local customs: 1 ) rural music is the most important factor constituting these seasonal customs by enriching the functions and connotations; 2 ) With its keen local charac-teristics, distinctive quality of including spells, and carrying a religious sensibility, games are part and parcel to seasonal customs; 3 ) Different cul-tural circles are accompanied by different customs and habits. So there are differences between inland and coastal or island areas, and even within the coastal area, differences can occur among particu-lar sea areas.

人权观念的工具理性与我国人权外交的合理选择

人权是一种自然属性和社会属性、普遍性和特殊性相结合的权利。人权外交也是人类在国际社会追求普遍道德原则的结果。但是,在人权外交领域,由于各国历史背景、经济文化、社会制度不同产生了诸多人权问题。中国在选择人权外交时应遵循国际法准则和国际社会公认的人权公约并以此为标准,在国际社会提倡以和平的方式解决人权冲突、化解人权危机,反对以人权为工具的“新干涉主义”行为。
