广西右江盆地利周-河口剖面极低级变质带的伊利石结晶度与粘土矿物光谱标志对比研究

为了检验高光谱遥感技术划分极低级变质带的应用潜力,进行了广西田林利周-河口剖面粘土矿物成分和伊利石结晶度Kubler指数XRD测量以及泥岩可见光-短波红外反射光谱测量.运用伊利石结晶度Kubler指数将下三叠统罗楼群和中三叠统百逢组下段划归浅变质带;将中三叠统百逢组上段和河口组划归近变质带,中三叠统百逢组上段为高级近变质带;将中三叠统上部河口组划归低级近变质带.基于1个K.I△2θ°0.43的测量值,不排除局部为成岩带的可能.在地层柱上自下向上,伊利石结晶度Kubler指数由小变大,变质程度由高变低,而且变质作用级别与岩层在地层柱中位置协调以及变质带边界与地层线趋于一致,证明为区域埋藏极低级变质作用.从地层柱下部到上部,新鲜岩石粘土矿物2200 nm附近吸收峰向短波方向移动.伊利石也有同样的吸收光谱迁移规律.这表明,随变质温度的升高,矿物光谱吸收峰向长波方向迁移.风化岩石和黑色岩石不适于极低级变质带的航天、航空遥感技术划分.但是,根据新鲜岩石吸收光谱迁移规律,可以用便携式野外光谱仪沿地质剖面,由新鲜岩石光谱划分地层单元和极低级变质带.

Effect of Land Use Conversion from Rice Paddies to Vegetable Fields on Soil Phosphorus Fractions

Excess phosphorus （P） from agricultural soils contributes to eutrophication in water bodies. Samples （n = 60） were taken from sites where rice paddies have been converted to vegetable fields for 0, 〈 10, 10-20, and 〉 20 years and analyzed for five inorganic P （Pi） fractions, three organic P （Po） fractions, and several soil parameters to investigate how land use conversion affects Pi and Po fractions in a peri-urban area of China with soils characteristic of many agricultural areas of Asia. Significant increases of 33, 281, 293, and 438 mg kg-i were found for soluble and loosely bound Pi （SL-Pi）, aluminum-bound Pi （Al-Pi）, calcium-bound Pi （Ca-Pi）, and iron-bound Pi （Fe-Pi）, respectively, after conversion from rice paddies to vegetable fields. Most of the increase in Pi was in the form of Fe-Pi, which increased from 8% of total P （TP） on paddy soil to 31% on the soil with 〉 20-year vegetable cultivation, followed by Al-Pi, which increased from 2% to 19% of TP. For Po fractions, there was no significant change in P concentrations. The conversion of land use from paddy fields to high intensity vegetable fields was causing significant changes in soil P fractious. Management practices were causing a buildup of soil P, primarily in the Fe-Pi fraction, followed by Ca-Pi and Al-Pi fractions. If current trends continue, a 30%-70% increase in TP could be expected in the next 20 years. Farmers in the area should reduce P application and use to maximize P uptake.

Does Working Capital Cause Profitability？ --The Nigerian Experience

The paper investigates the long run relationship and causality issues between working capital and profitability in 66 firms in Nigeria by using the panel cointegration method for the period 1999-2007. The empirical results show that there is long run steady-state relationship between working capital and profitability. However, the short run causal relationship runs from working capital to profitability suggesting that inefficient working capital management may harm profitability.

An Overview of the Feasibility of Achieving Level 2 Building Information Modeling by 2016 in the UK

The aim of this study is to investigate the current status and feasibility of achieving Level 2 BIM （building information modeling） usage that is to be made mandatory by the UK govermnent on its projects by the year 2016. This study assesses the level at which organizational and practitioner knowledge of BIM is currently positioned. The UK government, being the largest public stakeholder client, has realized the benefits and advantages of BIM when used in procuring projects across their lifecycle in the built environment. A critical review of the BIM literature was carried out and the evidence base was created in relation to government targets for 2016. At the current stage, Level 2 BIM adoption is achievable by 2016 for large construction firms but not for SMEs （small medium enterprise）. Also, from evidence in this study, the technology needs to be properly tailored to meet SME variables if Level 2 status is to be achieved for the entire industry.

Discussion on the problems and countermeasures in the financial management of the small and micro-sized enterprises

The survival problems are always the core problems of the small and micro-sized enterprises in our country, and the financial management, as the important key factor influencing the small and micro-sized enterprises, has more and more impact on its survival and development. However, the important problem existing presently is that the significance of the financial management is mostly ignored in the small and micro-sized enterprises, pursuing the short-term economic benefit blindly, which decreases the risk resistance of the small and micro-sized enterprises severely, so that a mass of the small and micro-sized enterprises with poor survivability and extremely short life cycle are occurred. This text analyzes the problems existing in the financial management of the small and micro-sized enterprises around the above several prominent problems, and discusses the corresponding suggestions to promote the sound development of the small and micro-sized enterprises in our country.

The Impact of Turnover Ratios on Jordanian Services Sectors＇ Performance

Profitability ratios are a group of financial ratios that indicate how much profit a business is earning within a certain context, while asset utilization ratios indicate how efficient a business is in operating its assets to generate cash. The difference between profitability ratios and turnover ratios is the fact that turnovers are more specific. While profitability ratios measure overall performance in terms of profits, asset utilization ratios focus on specific measurements within the business） We conduct this study to verify the impact of turnover ratios on Jordanian services sectors＇ performance during the period from 2009 to 2012. The study showed that there is no significant impact of turnover ratios on Jordanian services sectors＇ profitability, and by testing the main and sub hypotheses, the study revealed that there is no significant impact of turnover ratios on Jordanian services sectors＇ return on assets （ROA）, there is no significant impact of working capital turnover on Jordanian services sectors＇ ROA, there is no significant impact of total asset turnover on Jordanian services sectors＇ ROA, and there is no significant impact of fixed asset turnover on Jordanian services sectors＇ ROA. Also, the study showed that there is no significant impact of turnover ratios on Jordanian services sectors＇ return on equity （ROE）, there is no significant impact of working capital turnover on Jordanian services sectors＇ ROE, there is no significant impact of total asset turnover on Jordanian services sectors＇ ROE, and there is no significant impact of fixed asset turnover on Jordanian services sectors＇ ROE. Moreover, the study concluded that the educational services sector has the lowest working capital turnover and healthcare services sector has the highest. In addition, we find that the hotels and tourism sector has the lowest total asset turnover ratio, while the utilities and energy sector has the highest and that the hotels and tourism sector has the lowest fixed asset turnover, while the utilities and energy sector has the highest. The transportation sector has the lowest ROA and technology and communication sector has the highest. Finally, we find that transportation sector has the lowest ROE and the technology and communication sector has the highest.

Thales of Miletus, Archimedes and the Solar Eclipses on the Antikythera Mechanism

Thales of Miletus （640？-546 BC） is famous for his prediction of the total solar eclipse in 585 BC. In this paper, the author demonstrate how Thales may have used the same principle for prediction of solar eclipses as that used on the Antikythera Mechanism. At the SEAC conference in Alexandria in 2009, the author presented the paper ＂Ten solar eclipses show that the Antikythera Mechanism was constructed for use on Sicily.＂ The best defined series of exeligmos cycles started in 243 BC during the lifetime of Archimedes （287-212 BC） from Syracuse. The inscriptions on the Antikythera Mechanism were made in 100-150 BC and the last useful exeligmos started in 134 BC. The theory for the motion of the moon was from Hipparchus （ca 190-125 BC）. A more complete investigation of the solar eclipses on the Antikythera Mechanism reveals that the first month in the first saros cycle started with the first new moon after the winter solstice in 542 BC. Four solar eclipses 537-528 BC, from the first saros cycle, and three one exeligmos cycle later, 487-478 BC, are preserved and may have been recorded in Croton by Pythagoras （ca 575-495 BC） and his school.

Lake-margin ecosystems of saline lakes of the Borzya group(Zabaikalsky Krai, Russia) during the initial filling phase

This article presents the results of hydrochemical and hydrobiological studies of shallow saline lakes of the Borzya group(Zabaikalsky Krai, Russia) at the initial filling phase. The lake-margin ecosystems of the studied lakes are characterized by varying degrees of salinity from polyhaline to brine water. Cyclical variations of meteorological conditions and high salinity determined that the compositions of the aquatic organisms are specific, mostly between stenohaline and euryhaline species, the quantities are low, and the community structures are simple.

Shakespeare＇ s Sonnets Dated

By using echoes in some sonnets to lines in certain plays, emphasizing those echoes which were not later repeated, and by applying dates to those plays, in 1926 Elizabeth Beckwith tentatively dated a third of the 154 in the entire sonnets cycle. Her belief was that an unintentional authorial pattern of usage would be less subjective than other approaches to dating the sonnets. Yet, by use of dates from external allusions later applied by Prof. Leslie Hotson and other scholars, this author suggests that it may be possible to extend the total number of datable sonnets to over half of the cycle. However, Beckwith did not use dates for the plays which were later to become a standard dating scheme accepted by most scholars today, and so adjustments of her dates would change the dates she awarded to many of her selected sonnets. This author suggests that even the standard dating scheme is flawed, particularly if Shakespeare was dead when the Sonnets were published in 1609. He suggests another dating regime that meshes quite well with both Beckwith＇s 52 and an additional 27. Thus, the result for the 79 sonnets is to avoid certain problems in the distribution that Beckwith＇s method generated. The net result is what Beckwith termed ＂a skeleton around which the remaining sonnets can be safely built＂, but for over half rather than only a third of the cycle. This author suggests a half＂skeleton＂ is more indicative of the chronology for the whole sonnets cycle than only a third.

Recovery Capacity of the Finance System of Italian Municipalities After the Currency Crisis of 1992

This paper is a first pioneering attempt to apply the concept of resilience to the analysis of the public finance systems of local governments, a concept already used and ＂abused＂ in various disciplines and fields of science. In particular, it proposes an attempt to estimate the recovery capacity of Italian Municipalities in a crucial period of our country＇s financial history, between 1992 and 2000, or between the currency crisis and the introduction of the Euro. However, the analysis also involved the subsequent trends, in order to demonstrate that the current vulnerability of the municipal public finance system, in particular of the Municipalities of Southern Italy, depends not only on the economic cycle but also on the continuous and incessant changes in the financing mechanisms of local governments established by the central government. The analysis showed a lower financial resilience of the Municipalities of the Mezzogiorno （island and continental） compared to those of the Center-North. The determinants of this phenomenon were found, for one part, through the analysis of the financial data of the Italian Municipalities - as presented by the SVIMEZ in its annual reports on the economy of the Mezzogiomo - and, for another part, through the critical synthesis of significant economic events which occurred during the period examined.

Recovery Planning and Management Control System in Company Crisis

The main goal of this paper is to analyze situations of financial crisis in Italian companies. The analysis has also been focused on the company＇s attitude to overcome the financial crisis. Secondly, the authors have analyzed if the recovery project has required the introduction of a new management control system or changes to the existing management control system. The methodology is composed of several steps. First of all, the authors have analyzed the existing literature. Secondly, the authors have referred to a sample of 98 Italian recovery projects formalized by Italian private companies. The analysis of the literature and the recovery projects permits to achieve some provisional results, which have been tested through surveys. The methodology approach is inspired by the grounded theory. The findings have been several： （1） The crisis is a usual event in the lifecycle of a firm, due to a deterioration of its strength and a change of the context; （2） The timing factor has played a fundamental role in managing the crisis situation, because a late identification of the symptoms or a minimization of them can generate an irreversible situation; and （3） In addition, a recovery project includes the introduction of a new management control system or changes to the existing management control system. These new or modified management control systems use ＂feed-forward＂ mechanisms, which make early predictions about the changes in the characteristics of the competitive framework.

Central and Peripheral Cultures and the Problem of Social Conflict in Vietnam

This article deals with relationship between cultural globalization and local cultures, seen mostly as conflict between centre and peripheries on the world scale and also as conflict among ethnicities in the societies. It also suggests some solutions to the problem of conflict on the global scale in general and in Vietnam in particular. In the era of globalization, there exists a risk of cultural imperialism rising as a cultural centre. Nevertheless, the cultural imperialism always bears the economic and political motives. This is the very cause which leads to politico-cultural conflict. Therefore, in essence, cultural hegemony is also the very economic hegemony and it serves the economy. Thus, in fact, social conflicts are often the contradictions, but these contradictions could lead to conflict only when they are pushed to political and economic interests level, and then they are the truly economic and political conflicts and not cultural ones. Therefore, in essence, there are not purely cultural conflicts, but culture is only the medium for politico-economic conflict. There may be various kinds of solutions for the problem of conflict： the economic solutions, the social solutions, the political solutions, and the cultural ones. Vietnarrv--as a multi-ethnic natiorv--is not a country without social conflict. To solve the problem of conflict is to solve the contradictions in economic interests and to overcome the lack of democracy. Therefore, the most important solutions for the problem of conflict are the cultural and political solutions. Especially, the article emphasizes the democracy and the rule of law as the critical points in solving the problem of social conflict.

United States and France： Imprisonment and Torture From the End of WWII to the Algerian War

Mistreatment and violation of international laws are recurrent events during Second World War （WWII） and torture is a frequent method used in the Algerian War. This paper investigates the escalation of violence which, in some cases, degenerates into torture and offers a comparison between the situation of Axis Prisoners of War （1943-1946） and the imprisonment’s conditions in Algeria （1954-1962）. In spite of the temporal interval and different political contexts, in some cases there’s a strange “continuity”.
