Traditional Values and Modernization Challenges in Forming Urban and Rural Culture. 25. When, on the other hand, we face the nondialectic conception of tradition, when we become witnesses of its abuse, then it takes over traditionalism significances, by getting a predominantly negative connotation. Then the contemporary sense of culture becomes passive and completely captured in disciplines of the past, patriarchal and conservative times. It can usually be recognized in the absolution of past, myths, prejudices, outdated ideologies, and values in firm concepts of understanding and social behav.

The broad cultural heritage of a society-Protestant, Roman Catholic, Orthodox, Confucian, or Communist-leaves an imprint on values that endures despite modernization. Moreover, the differences between the values held by members of different religions within given societies are much smaller than are cross-national differences. Once established, such cross-cultural differences become part of a national culture transmitted by educational institutions and mass media.

Earth construction is an appropriate method for building houses in arid and semi-arid areas in Ghana due to its low environmental impact and responsible use of on-site resources.
TRADITIONAL CULTURES AND MODERNIZATION: Several Problems in the Case of Japan. HIRAI Naofusa. It is known that modernization, as far as technology and science are concerned, emerged after the Industrial Revolution, which was triggered by the invention of spinning machinery in England during the late eighteen century. In Japan as well as in other Asian countries modernization has often been confused with Westernization. This is because modernization, when it occurred in these countries, quite often meant accepting Western culture and resulted in great changes of everyday life. However, Prof. . *4 Josefa M.

As for modernization in India, we find a growing trend that traditional role-structures are giving way to modern ones. But persons following these roles often retain categorical values of tradition instead of those of modernity. We have mentioned how caste itself is adopting many functions which properly belong to rational corporate groups. Generally, ritual order and religion which are essentially based on categorical values of a traditional nature do not show evidence of decline, nor is there an easy possibility of their disappearance in the near future.

Modernization theory is used to explain the process of modernization within societies. Modernization refers to a model of a progressive transition from a 'pre-modern' or 'traditional' to a 'modern' society. Modernization theory originated from the ideas of German sociologist Max Weber (1864–1920), which provided the basis for the modernization paradigm developed by Harvard sociologist Talcott Parsons (1902–1979). The theory looks at the internal factors of a country while assuming that with assistance.

Redox economy in organic synthesis Academic Article

Total synthesis of marine natural products without using protecting groups, Nature, 2007, 446, 404-408.

This Review brings to attention another form of economy which should be considered in the planning and evaluation of a multistep synthesis: redox economy.

Use of the recently developed direct indole coupling enabled an efficient, practical, scalable, and protecting-group-free synthesis of each of these natural products.

Redox economy in organic synthesis ..

Several guidelines and examples are included to illustrate the logic of this approach and to stimulate the design of syntheses.

While any sort of economy will help to streamline the effort of total synthesis, redox economy addresses a particularly weak area in present-day total synthesis.

It is not enough to point out the present deficiencies, rather the purpose of this Review is to serve as a teaching tool for all practitioners of the field by giving and illustrating guidelines to increase redox economy in multistep organic synthesis.

Protecting-group-free synthesis as an opportunity for invention, Nature Chemistry, 2009, 1, 193 – 205.

Redox Economy in Organic Synthesis

Biochemistry may be described as the study of living systems, using the methods of chemistry and physics. Life is a complex of interrelated chemical reactions. Even the structural features on which taxonomic classifications are mainly based are the products of chemical reactions. In any case, structure, since it survives nearly intact when a cell or organism dies, is clearly not life, although a high degree of structure is probably required for life. Disruption of the interrelated chemical activities of an organism is death; by the same token, these chemical activities, collectively, are life.”

Principles for designing economical multistep organic synthesis

A concise and highly enantioselective synthesis of colchicine (>99% ) in eight steps and 9.3% overall yield, without the need for protecting groups, was developed. A unique Wacker oxidation was used for enabling regioselective construction of the highly oxidized and synthetic challenging tropolone C-ring. Furthermore, asymmetric syntheses of β-lumicolchicine and -acetylcolchinol--methyl ether (NCME) were achieved. Notably, NCME was synthesized from β-lumicolchicine by an unusual decarbonylation and electrocyclic ring-opening cascade reaction.

The polyketide natural product (+)-SCH 351448, a macrodiolide ionophore bearing 14 stereogenic centers, is prepared in 14 steps (LLS). In eight prior syntheses, 22–32 steps were required. Multiple chemoselective and redox-economic functional group interconversions collectively contribute to a step-change in efficiency.
