Many researches have revealed that inappropriate and unhealthy institutional environment has resulted in to teacher’s increased level of alienation, low morale and job dissatisfaction affecting their professional commitment adversely. Psychologists emphasized that human working environment is extremely important. It depends on teacher’s own perception as to what will make him unhappy or dissatisfied. Rewarding and supporting, good achievement, organizational involvement influence teacher’s professional commitment. All the hypotheses were tested statistically by applying t-test on the dependent variable, professional commitment. Two groups defined as above mean and below mean were formed. High professional commitment emerged 170 college teachers while low professional commitment have 80 college teachers. Overall generalization is that these environment specific factors significantly affect college teacher’s professional commitment. Quality of environment plays an important role in the development of college teacher’s professional development. In order to improve the quality and standards of higher education the Education Commission (1964-66) made a number of recommendations. The National Policy on Education (1968) was a significant step in this direction. While the achievement of these policies were impressive, the system of higher education remained weak and grew weaker year after year. The Government of India, then, formulated and issued another policy in 1986 which considered higher education a “crucial factor for survival”. This policy hinted upon improving and strengthening the organizational behaviour of college and universities and made several suggestions for making the system work” emphasizing that “All teachers should teach and all students study”. Not much could come out of this also. College teacher’s organizational behaviour ditched still further. This necessitated investigation into the determinants of the quality and standards of higher education. Undoubtedly, there can be a number of such factors and conditions. But, the teacher and his organizational behaviour may be considered the most basic factor. Quite a large number of college teachers and academicians in their informal talks express that since long professional commitment of teachers has been missing in colleges and universities for several reasons. This has rendered all efforts of government on qualitative improvement of higher education ineffective. This may or may not be correct. But, it seems imperative to establish the current status of college teachers’ professional commitment and also to identify factors and conditions that determine its high and low status. This may help administrators and policy makers to be more knowledgeable in this regards. This may also enable them to take appropriate action for boosting status of teachers’ professional commitment. Many concerned people in the field, quite frequently, ascribe the reason for this lack of commitment to various factors ranging from government’s inappropriate policies and administrative decisions to institutional environment and lack of teachers’ competence. Many researches have revealed that inappropriate and unhealthy institutional environment has resulted into teachers’ increased level of alienation, low morale and job-dissatisfaction affecting their professional commitment adversely. Hence, it is emphasized by psychologists and social scientists that understanding of human working-environment is extremely important if effective human functioning is to be ensured. Environment is a highly elusive concept and may include any condition that affects teachers’ professional commitment. It depends on teachers’ own perception as to what will make him unhappy or dissatisfied. But, some environment-specific factors may be commonly perceived as derogatory to their professional commitment. It is proposed to find out how the following environment-specific factors influence teachers’ professional commitment. 1. Rewarding and supporting environment. 2. Emphasis on goal-achievement. 3. Organizational involvement. It is hypothesized that presence or absence or emphasis on these in the environment of college may be linked in some way with college teachers’ professional commitment.

In Ivory Coast, the majority of uncontrolled dumpsites are open-air. The aim of this work is to study the lateral and vertical distribution of heavy metals or metalloids in soils surrounding the open dumpsite of M’Ploussoue Park in Bonoua, which has a wet tropical climate and located at upper topographical position. The physical and chemical parameters, such as the particle size, pH, exchangeable cations, CEC and contents of heavy metals, were studied using various analytical techniques. The vertical and lateral distribution of heavy metals or metalloids in soil samples collected from the M’Ploussoue dumpsite in Bonoua were found to be in the following order: Zn > Pb > Cr > Ni > Cd > As > Cu > Se, regardless of the topographical position of the soil profile. Ours results indicate that there are high levels of heavy metals (Cr, Pb, Cd, Zn, Ni) that exceed the CCME permissible limits in agricultural and industrial soils in both the top soil layers and in soil located below the dumpsite, probably due to the migration and infiltration of dumpsite leachate. The vertical and lateral distributions of metals or metalloids at dumping sites can pose potential ecological risks if these elevated concentrations of metals migrate into soil, plants and groundwater, where they present a danger to humans. Thus, it appears to be necessary to apply proper remediation techniques.

This paper focuses on geological-genetic peculiarities of Goshian deposit formation. Considerable elements of corresponding conditions of gold-ore mineralization localization can be emphasized here, subvolcanic body and joined high-angle faults are the more typical among them. Sequence and stages of mineral formation process are studied and also distribution of precious metals in ores and sulfide concentrations. Ore bodies refer to vein-disseminated type and are confined to inside part of metasomatic aureole which is represented by quartz-sericite facies of secondary quartzites. It is expected during ore-formation process physic-chemical conditions varied from midwater (quartz-pyritic stage, early-ore) to shallow (quartz-arsenic pyrite-polymetallic with “hidden” gold) up to near-surface (quartz-gold-telluride, quartz-gold goethite-hydrogoethite stage). Formation of Gosha deposit occurred in relatively narrow temperature interval from homogeneous fluids of mainly Na-chloride composition with moderate and low salinity. It is established the temperature of ore-formation studied by homogenization method of gas-liquid inclusions in transparent minerals (quartz) of different mineral associations varies 140-390° C. Pressure of ore-forming medium calculated by isotherms cross in system H2O-CO2 and isochors CO2 is 0,7-2,0 Kbar.
