The Effect of Three Culture Methods on Intensive Culture System of Pacific White Shrimp (Litopenaeus vannamei)

Different culture methods may affect the intensive culture system of Pacific white shrimp(Litopenaeus vannamei) regarding water quality and growth and economic performance.This study evaluated the potential effects of three culture methods through cultivation of juvenile shrimps under consistent tank management conditions for 84 d.The three methods involved shrimp cultivation in different tanks,i.e.,outdoor tanks with cement bottom(mode-C),greenhouse tanks with cement bottom(mode-G) and outdoor tanks with mud-substrate(mode-M).Results showed that water temperature was significantly higher in mode-G than that in mode-C(P < 0.05).In contrast to the other two treatments,mode-M had stable pH after 50 d cultivation of shrimps.In the mid-late period,the average concentrations of TAN,NO2-N,DIP and COD were significantly lower in mode-M and mode-G compared with those in mode-C(P < 0.05).Despite lack of differences in the final shrimp weight among different treatments(P > 0.05),mode-M had significantly higher shrimp yield,survival rate and feed conversion rate(P < 0.05) than other modes.There were significant differences in revenue and net return among different treatments(P < 0.05).These demonstrated that the treatments of mode-G and mode-M were conductive to the intensive culture system of L.vannamei.

Effect of culture methods on individual variation in the growth of sea cucumber Apostichopus japonicus within a cohort and family

There is substantial individual variation in the growth rates of sea cucumber Apostiehopus japonicus individuals. This necessitates additional work to grade the seed stock and lengthens the production period. We evaluated the influence of three culture methods （free-mixed, isolated-mixed, isolated-alone） on individual variation in growth and assessed the relationship between feeding, energy conversion efficiency, and individual growth variation in individually cultured sea cucumbers. Of the different culture methods, animals grew best when reared in the isolated-mixed treatment （i.e., size classes were held separately）, though there was no difference in individual variation in growth between rearing treatment groups. The individual variation in growth was primarily attributed to genetic factors. The difference in food conversion efficiency caused by genetic differences among individuals was thought to be the origin of the variance. The level of individual growth variation may be altered by interactions among individuals and environmental heterogeneity. Our results suggest that, in addition to traditional seed grading, design of a new kind of substrate that changes the spatial distribution of sea cucumbers would effectively enhance growth and reduce individual variation in growth of sea cucumbers in culture.

The Way to Improve the Teaching Quality of the Special English Curriculum for Medical Laboratory Science

Phenomenon: Nowadays, with rapidly developing in medical laboratory science(MLS), new concepts, knowledge and technologies are constantly emerging, which requires medical students to continuously learn to grasp the new development trend and the latest research progress. To enable the students to learn and make use of scientific knowledge better, the Special English Curriculum for MLS has been set up, which is very important to non-English-speaking students. However, there are many problems in the course of teaching, so the improved teaching quality of the curriculum is in demand. Approach: In this paper these problems are described and the corresponding advices are proposed from the perspectives of staff room, teachers and students, which are supposed to develop the curriculum for education of the medical laboratory scientists. Findings: To improve the teaching quality of the Special English Curriculum for MLS, the textbook should be appropriately selected or compiled, the novel teaching methods can be applied, and the modern multimedia teaching materials can be adopted.The teachers of the curriculum should be proficient in professional knowledge, English as well as the systematic and scientific teaching methods. The students need to have the courage and determination to overcome the difficulties when they learn the curriculum, and the students who have not did well in their lessons should learn to study by themselves. Insights: The Special English Curriculum for MLS is very important to non-English-speaking students and is kind of difficult for them, the staff room, teachers and students should adjust themselves to teach and learn the curriculum better.

The Two Cultures of Science: Implications for University-Industry Relationships in the U.S. Agriculture Biotechnology

Partnerships between U.S. universities and industries have existed for several decades and in recent years have become generally more varied, wider in scope, more aggressive and experimental and higher in public visibility. In addition, in the last few decades, public and private interests have advocated for government policies and laws to globally promote the commercialization of university science. This paper examines the persistence or convergence of the two cultures of science and the implications of this commercialization for university-industry relationships in agriculture biotechnology. The perceptions and values of over 200 U.S. university and industry scientists, managers and administrators who participate in or oversee research collaborations in agricultural biotechnology were analyzed. The findings revealed that the participants in these research relationships continue to perceive very distinct cultures of science and identify a wide range of concerns and disadvantages of these partnerships. Several actions were discussed to ensure that the two cultures serve complementary roles and that they maximize the public benefits from these increasing collaborations.

This comparison is made form two aspects about clothing culture. One is the separate characteristics of the Chinese and British clothing. The other is the common features of the Chinese and British clothing.The paper aims at making the Chinese confidently promote the clothing culture of China to make efforts to realize the great rejuvenation of China and enrich the culture of all mankind.

An Evolutionary Approach to the Delineation of Functional Areas Based on Travel-to-work Flows

This paper presents a new approach to the delineation of local labor markets based on evolutionary computation. The aim of the exercise is the division of a given territory into functional regions based on travel-to-work flows. Such regions are defined so that a high degree of inter-regional separation and of intra-regional integration in both cases in terms of commuting flows is guaranteed. Additional requirements include the absence of overlap between delineated regions and the exhaustive coverage of the whole territory. The procedure is based on the maximization of a fitness function that measures aggregate intra-region interaction under constraints of inter-region separation and minimum size. In the experimentation stage, two variations of the fitness function are used, and the process is also applied as a final stage for the optimization of the results from one of the most successful existing methods, which are used by the British authorities for the delineation of travel-to-work areas （TTWAs）. The empirical exercise is conducted using real data for a sufficiently large territory that is considered to be representative given the density and variety of travel-to-work patterns that it embraces. The paper includes the quantitative comparison with alternative traditional methods, the assessment of the performance of the set of operators which has been specifically designed to handle the regionalization problem and the evaluation of the convergence process. The robustness of the solutions, something crucial in a research and policy-making context, is also discussed in the paper.

A Brief Study on Culture Shock over Overseas Students and the Solution to New Cultural Environments

Culture shock is one of the common experiences by students and people abroad. They may experience the feeling of anxiety, disorientation, confusion, and even hostility because of misunderstanding to each other."Culture shock"refers to the phenomenon in which people engage in the interaction feel depressed, discomfortable, etc. Culture shock may be caused by the conflict of various value systems when students and people enter a new culture and other value system. Culture shock is also a consequence of the influence of the negative life event. The changes in one's life and lack of support from family members,friends will make them more vulnerable and cause great discomfort in the new environment.

Attitudes of young scholars in Qingdao and Hamburg about climate changeand climate policy The role of culture for the explanation of differences

This article analyses differences in the attitudes related to climate change of young scholars in environmental science in Qingdao (China) and Hamburg (Germany). The main aim of the article is to evaluate the role of cultural differences for their explanation. We expect no significant differences in the attitudes related to the findings of climate research, since scientific principles are the joint basis of the scientific discourse wordwide. However, we expect that there are differences in the attitudes of the young scholars about the role of science, of the state and of the civil society for dealing with the challenge of climate change. We suggest that these can be explained with substantial cultural differences between both societies, with regard to the role of the state and the civil society for the solution of environmental problems. In order to evaluate these hypotheses, we have conducted a comparative survey among environmental science students in Qingdao (China) and Hamburg (Germany) about their attitudes towards climate change. The findings support our main hypotheses. The young scholars in Qingdao and Hamburg differ substantially in their views of the role of science in society and policymaking. Plausibly, these differences may mainly be explained with differences in the cultural ideas about the role of the state and of the civil society for the solution of environmental problems. Gradual differences in the share of young scholars who think that climate change has anthropogenic causes, may be explained with differences in the curriculum but also by cultural habits. This article makes a new contribution to the scientific debate by exploring the role of cultural differences for differences in the attitudes of young scholars in environmental science in connection with climate change and climate policy in different cultural contexts.

Historical Course Follows Climate Change: Patterns of the Northern Hemisphere — From Peoples’ Migration until the Industrial Revolution (3^rd-18^thCentury)

This paper relates to the statement that the so-called “Little Ice Age” (RCC 6: 1.350-1.800 A.D.) represents—besides the 8k-Event (8.200-8.000 yr cal. B.P.)—the fastest and strongest onset in Holocene History [1]. Its intention focuses on the correlation of interplaying natural processes (i.e. solar energy variation, aerosols, oceanic currents, volcanism as part of plate tectonics, heat flow) with social/political evidence through the time-span of Peoples’ Migration until Industrial Revolution (3rd-18th Century). The time-span comprises the cool/wet/respectively dry climate phase of the P.M. (260-550), a Climate Optimum (600-1.100 A.D.) owning a final Thermal Maximum (1.100-1.260 A.D.) and the “little Ice Age” (1.350-1.800 A.D.), the latter intercalated by the Sp&#246;rer Minimum (1.460-1.550 A.D.) and the Maunder Minimum (1.650-1.720 A.D.). Thereby, an average temperature difference of 1.0&#176;C - 2.0&#176;C seems sufficient for incising climatic/cultural consequences [2]. It has become obvious that a Climate Optimum primarily provides constructive life conditions;however with a problematic final as the following “Effect-Chain” tells: balanced agricultural/cultural population growth → rich harvests → satisfying nourishment → health, encouragement → overpopulation under favorable materialistic conditions → increasing stress → lack of food, high prices → revolts → migration. In contrast, cool/wet/resp. dry conditions originate destructive/depressive conditions (see Peoples’ Migration) which initiate the following “Effect Chain”: bad agricultural conditions → poor/no harvesting → famine → disease, growing death rate → social, political revolts, wars → human cruelties with psychic/religious background (inquisition, witch-combustion → general chaos (30 yr-war) → death, migration (maritime endeavors, colonization). Furthermore, it should be stressed that volcanic aerosols play besides the solar influx variation—an important role on climate/cultural change [3]. However, the effects of oceanic currents’ heat flow of Mid-Oceanic Ridges and Hot Spots, as well as Earth-Magnetism and Sun/Earth Geometry are poorly understood in this context (Example: Iceland as hot spot situated on the Mid-Atlantic Ridge having been working since 40 Ma). The Chapter-introducing citations play a challenging role in regard to Science Criticism and touch the so-called 95% Confidence line (accepted realm of causal interrelation and according recommendation to Society [4]).

On the Cultural Contents and Settlements of Northern Taiwan’s Prehistoric Peoples

This paper makes use of the most recent archaeological data to examine and present the lifestyles at prehistoric settlements of northern Taiwan,in order to understand the developmental changes in the appearances of cultural contents and settlement patterns of these prehistoric cultures of northern Taiwan over several thousand years.On the basis of current archaeological data,it is clear that Shuntanpu Early Culture,Shuntanpu Late Culture,Yuanshan Culture,Botanical Garden Culture,and Shihsanhang Culture all had stilt-type(raised-platform)housing.Wooden pillars were erected in round holes of approximately 10-20 cm(though some are larger)dug into the earth,gravel layer,or sandstone bedrock,and it is surmised that these were then made more stable by packing small stones or ramming earth into the holes around the pillars.Coming to the long-standing controversy as to the origins of the Shihsanhang Culture,Shihsanhang Culture clearly inherited important content from the prehistoric cultures that inhabited northern Taiwan over the previous several thousand years and represents the developmental evolution of northern Taiwan archaeological cultures.One other aspect:Shihsanhang Culture has a stronger maritime character.Not only did it have frequent contacts with other contemporaneous archaeological cultures in Taiwan,but also conducted trading interactions with people in China and Southeast Asia,shaping Shihsanhang’s complex and unique cultural appearance.

Against the Authority of Books:Hobbes and the Invention of Political Science

In an age when political thinkers were writing books full of quotations of ancient and modern authors,Thomas Hobbes of Malmesbury(1588-1679)developed a philosophical system which was based on scientific method rather than on the authority of books.He emphasized that the absurdities that philosophers fall into are actually due precisely to a lack of method and to the habit of quoting other thinkers as if the truth was to be found in their words.It is certainly not inappropriate to read what philosophers,historians,and poets wrote,whether for pure amusement or to find intellectual spurs useful for one’s own research and speculation;but the written word should not be confused with the truth.In the investigation aimed at discovering the truth in political matters,the philosopher must use his own intellect,relying on the strength of reasoning.Thus,political philosophy becomes a science:the science of“consequences from the accidents of politic bodies”.With his reflections on scientia civilis,Thomas Hobbes may be considered the inventor of political science.
