Lawyers＇ Perceptions and Attitudes Towards the New Information and Communication Technologies （ICTs）： A Case Study of the Southern Professional Institute （IPReS） From the Federal State University of Morelos （UAEM）

A quantitative, non-experimental, and cross-sectional descriptive study was conducted to analyze the perceptions and attitudes of attorney teachers, from the Southern Professional Institute （IPReS） of the Federal State University of Morelos （UAEM）, towards the new information and communication technologies （ICTs）. The investigation was conducted by the method of survey and gathering information through the application of teachers＇ Attitudes Questionnaire to Computers derived from the instrument ＂Teachers＇ Attitudes Toward Computers＂ of Christensen and Knezek （1996） to the total teachers with a law degree who work at the institute. The dimensions involved in the questionnaire were： liking/utility, email, frustration/anxiety, learning/productivity, and negative impact. The results projected in the study reflected that teachers have a positive attitude （medium to favorable） with respect to computers and emails. In addition, the results showed the absence of teachers＇ feelings of anxiety, nervousness, or fear towards using computers.

Some Remarks on the Role of Tamil Literary Tradition in Siva Satakam of Narayana Guru

The paper presents an analysis of the selected stanzas of Siva Satakam （One Hundred Verses on Siva）--the most important hymn devoted to Siva composed in Malayalam by Narayana Guru. The analysis shows that there is a tendency in the hymn to emphasise the equal status of Sanskrit and Dravidian literary tradition. Several stanzas are constructed on the basis of Sanskrit stories or myths; however, this ＂classical＂ scheme is filled with Tamil or Malayalam concepts, ideas, and key words. What is more, Narayana Guru employs so called twilight language used by authors of Tamil philosophical works in order to provide a receiver of the poem with the opportunity to interpret some stanzas in accordance with Sanskrit as well as Dravidian tradition. The introduction of a person belonging to lower caste of South India as the one who is able to attain liberation, as well as presentation of the welt-known philosophical concepts as equal or even subordinated to the Dravidian ideas could become a significant contribution to the social activity of Guru comprising among others the concern for spiritual and social uplift of the lower caste people of Kerala.

Urban Utopia and Building Experimentations： The Rural Villages of the Sicilian Latifundium

The colonization of Sicilian latifundium was an attempt of regeneration of the rural areas. It was carried out by Benito Mussolini, called II Duce, who governed Italy by a regime with an absolute and conservative approach for 20 years since 1922. According to this plan, there were some rural villages （with a school, a church, a police station and a doctor＇s surgery） and a number of rural homes, spread in the landscape, that formed one of the most important achievements of the agrarian reform in Italy. The author has been conducting scientific research on this topic for several years. He started with the archive ＂Ente per la Colonizzazione del Latifondo Siciliano＂ （now called Ente Sviluppo Agricolo） to review the original designs and contracts with companies, ledgers and other administrative documents. Lately, he has been reviewing the personal archives of designers involved in the building program, where he has found original drawings, letters, sketches, etc.. He has also conducted some architectonic and technical surveys of the sites. We have to consider that nowadays the mentioned rural villages are a strategic resource for the development of the neighboring areas, as it may become a network for the sustainable tourism and the promotion of the local agro food specialties. On this purpose, the local authority is going to promote some plans for the requalification of these sites. The particular achievement of this article is to show a number of possibilities for the reuse of these places.

Breeding biology of the Spot-billed Pelican(Pelecanus philippensis)in Karaivetti Bird Sanctuary,Tamil Nadu,India

The breeding biology of the Spot-billed Pelican(Pelecanus philippensis)was investigated from September 2007 to September 2010 in Karaivetti Lake,Tamil Nadu,India.The Spot-billed Pelican breeds between November and April at the Karaivetti Lake.It also breeds roughly during the same period at other breeding sites in Tamil Nadu,except for the Vedanthangal and Karikili bird sanctuaries,where pelicans arrives much earlier and their breeding activities start and end to some extent ahead of the other sites,i.e.,from September to March.In essence,the breeding season starts after the onset of the northeast monsoon in Tamil Nadu.A few days after their arrival,pelicans perform courtship display,form pairs,start nest construction and lay eggs.Courtship display is not as attractive and impressive as in other waterbirds.The clutch size varies from two to three eggs and the incubation period from 25 to 36 days.The fledging period varies from a minimum of 90 to a maximum of 102 days.The nest success rate of the Spot-billed Pelican at Karaivetti was 90.28% during the study period.

Problems in the Field of Systematics and Investigation of Conifers in Russia

The largest and most important family in Russian conifers is Pinaceae （27-29 species）. The most important problems in the field of systemitics concern some critical taxa. In the result of author＇s research, the new signs of vegetative and reproductive organs have been checked out and elaborated. It leads to the clarifying of new taxonomic status and geographical distribution of certain critical taxa. A set of species are threatened and need special measures which are included into the Red Data Book of Russian Federation. for their conservation. There are 13 species and one variety

Radiation-Chemical Situation of the Waters of the Middle Reach of the River Yenisei （Russian Federation）

The results of monitoring the radiation-chemical situation in the middle reach of the Yenisei River located in the nearest zone of the influence of the Mining and Chemical Combine of Rosatom have been described in the paper. Using different physico-chemical methods, it has been found that uranium and tritium content in the water exceeds the background values of the flood plain of the River Yenisei. It has been shown that a wide range of radionuclides of different genesis flows into the waters of the Yenisei River. It has been demonstrated that radionuclides are transported by the water flow in the form of molecular solution or with suspended matter. In this case, the suspended matter consists of pelitic finely dispersed mineral particles, plant and organic detritus and living biological objects （for example, worms）. It has been shown that the main contribution to radionuclide and metal accumulation is made by humic substances covering the panicles of the suspended matter and actively participating in the formation of complexes with radionuclides and heavy metals. As a result of this work, the artificial radionuclide inflow into the ecosystem of the River Yenisei has been evidenced.

The Concept of the Higher/the Lower Energy in the Atmopadesa Satakam of Narayana Guru

The paper presents an analysis of the concept of the higher/the lower energy （para-apara maya/prakrti/sakti） in the Atmopadesa Satakam （＂One Hundred Verses of Self-instruction＂）, the most important philosophical work of Narayana Guru composed in Malayalam. In order to better understand the issue, the same pair of opposites is discussed at length on the basis of Narayana＇s earlier Malayalam poems--devotional hymns （Siva Satakarn--＂One Hundred Verses on Siva＂, Kah Natakam--＂Dance of Kali＂, and Janani Nava Ratna Manjari--＂Nine Gemmed Bouquet to Mother＂） as well as later Sanskrit philosophical work [Darsuna Mala--＂Garland of Visions＂）. The comparative analysis of these texts demonstrates that--whereas Darsana Mala reflects more or less accurately Vedantic concepts, Atrnopadesa Satakam presents deeply syncretic formation, influenced to a large extent by philosophical systems related to bhakti （devotion）, like Sata or Saiva Siddhanta. The reason for such a state of affairs could be the purpose of Malayalam work destined to become vehicle for instructions given to lower caste people in Kerala. The paper offers an analysis of the relevant passages of the texts accompanied with explanatory notes extracted from the commentarial literature.

A Fast Federated Learning-based Crypto-aggregation Scheme and Its Simulation Analysis

To solve the problem of increased computation and communication costs caused by using homomorphic encryption(HE) to protect all gradients in traditional cryptographic aggregation(cryptoaggregation) schemes,a fast crypto-aggregation scheme called RandomCrypt was proposed.RandomCrypt performed clipping and quantization to fix the range of gradient values and then added two types of noise on the gradient for encryption and differential privacy(DP) protection.It conducted HE on noise keys to revise the precision loss caused by DP protection.RandomCrypt was implemented based on a FATE framework,and a hacking simulation experiment was conducted.The results show that the proposed scheme can effectively hinder inference attacks while ensuring training accuracy.It only requires 45%~51% communication cost and 5%~23% computation cost compared with traditional schemes.
