This paper reviews constraints to crop production, the status of technology development and future research needs of the smallholder farms in the semi-arid areas of Zimbabwe. ZIMBABWE'S agricultural industry consists of two major sectors; the large-scale commercial and the smallholder (communal) sectors. Prior to 1980 production from the communal sector was largely for subsistence requirements....

• Highly communal people experienced low communion work environments as aversive. • They were also unlikely to accept a high status promotion in such an environment. • In contrast, low communal people were unconstrained by work environment communion. • On average, women scored higher in communion than men. • This may contribute to the underrepresentation of women in high status positions. a b s...

There is a well-known formula due to Andrews that counts the number of incongruent triangles with integer sides and a fixed perimeter. In this note, we consider the analagous question counting the number of k-tuples of nonnegative integers none of which is more than 1/(k−1) of the sum of all the integers. We give an explicit function for the generating function which counts these k-tuples in th...

the right to terminate and dissolution of administrative contracts is used because of two reasons: misconducts of contractors and maintaining the requisite of public interests. in the first, the causes of it have been noted explicitly in the article of 46 of the general terms of contracts. but about the second, it is necessary to note that the article of 48 of the general terms of contracts giv...

1. The behavior of a single bacterial cell toward gentian violet differs fundamentally from that of a small group of cells (thirty). 2. The explanation of this phenomenon is not purely quantitative; thirty cells accomplish much more than thirty times what one cell can accomplish.

This paper reports the findings of a national study of Black suicide. The main purpose of the analysis is to suggest a suitable explanation for the increasing suicide rate among young Blacks. I examined the possibility of a link between a weakening of communal and family ties and Black suicide, focusing on the "isolating effect" of inmigration and living alone. These variables were viewed as li...

INTRODUCTION A growing proportion of the global population rely on shared sanitation facilities, despite their association with adverse health outcomes. We sought to explore differences between neighbour-shared and communal latrines in terms household demographics, accessibility, facilities and use. METHODS We conducted surveys among 295 households relying on shared sanitation in 30 slums in ...

Parkinson's disease is a chronically developing neurodegenerative disease showing typical motor symptoms of the following triad: resting tremor, freezing of gait, and bradykinesia-hypokinesia. In the present study, we investigated the effects of a communal exercise program, using the visual and auditory feedback provided by a smart application, to assess gait ability, fear of falling, and fall ...

Systematic, well-designed research provides the most effective approach to the solution of many problems facing highway administrators and engineers. Often, highway problems are of local interest and can best be studied by highway departments individually or in cooperation with their state universities and others. However, the accelerating growth of highway transportation develops increasingly ...
