The recent upsurge of the desert locust Schistocerca gregaria (Forskål, 1775) has had an impact on East Africa and the Middle East as far as India. It has affected and slowed down many aspects of the Pakistani economy. Swarms of locusts have infested many areas and caused immense damage to all types of crops. Both farmers and economists are concerned and are trying to get the most up-to-date information on the best strategy to manage this pest. This paper is an attempt to (i) provide insight into the dynamics of this upsurge internationally as well as in the various regions of Pakistan, (ii) briefly assess its local impact and locust control measures, and (iii) clarify the role of the various stakeholders in the management, both nationally and internationally, suggesting various improvements for the future.

1. The permeability of perfused intimal sacs to fourteen non-ionic, hydrophilic molecules of graded molecular size was estimated by radioisotope flux. 2. The rectal cuticle acts as a molecular sieve severely restricting the rate of penetration of molecules with increasing hydrated size. 3. The penetration of test molecules was as predicted by the Renkin equation for a uniform population of water-filled pores having radii of 6.5 Å. 4. The properties of cuticles from the rectum and the integument are compared and the role of the rectal intima in the excretory process in the desert locust is discussed.

Insight Into

This chapter proposes to explore the writing of Gertrude Bell through a few prisms: first, her interest in history and archaeology, and second, her private letters. It will examine how Bell’s interest in archaeology mirrored her interest in politics: just as in her political role, in which she was building a state, Bell attempted through her archaeological work and photography to create a mythology about the Orient. Bell’s private letters also provide an insight into how she interacted with men and the role of this interaction in realising her political aims and in shaping her life. The chapter will examine how these interactions were informed by attitudes towards women in the Victorian world she inhabited, whether in England or the Middle East.

Business ethics in business training: Oratory or the actuality. This article is the culmination of an in-depth literature study. On the one hand an attempt is made to incorporate the views of different authors, while on the other hand an attempt is made to take part in the debate which is initiated by the current renewal of interest in the subject Business Ethics. Within this framework attention is paid to the question of whether business ethics can be taught and if so, to what extent it's influence will be felt. Secondly, an insight into the teaching of business ethics in the future is provided. Within this context the approach to the teaching, the content, the role of the student and the responsibility of the educator in particular are addressed. Opsomming Hierdie artikel is die resultaat van 'n indringende literatuurstudie. Daar word gepoog om enersyds verskillende skrywers se standpunte saam te vat, maar andersyds ook kritiese kommentaar te lower en deel te neem aan die debat wat deur die huidige opiewing in die belangstelling in Bestuursetiek bestaan. Binne die raamwerk sal aandag aan die volgende geskenk word: Die beantwoording van die vraag of Bestuursetiek onderrig kan word en indien wel die trefwydte daarvan. Tweedens 'n toekomsblik op die onderrig van Bestuursetiek.

Blind Spots

This project comes out of a conversation between Mohaiemen and Pajović, about the relative absence of Non-Aligned Movement co-founder Josip Broz Tito, from the three-channel film Two Meetings and a Funeral (2017, dir: Mohaiemen). In the film, a series of conversations between Vijay Prashad, Samia Zennadi, Atef Berredjem, Amirul Islam, and Zonayed Saki sketch out the shadow play of warring forces inside the Non-Aligned Movement, especially around the decolonizing nations of the Middle East, Africa, and Asia that found an option to look toward an "Islamic" supra-national identity. Because of that focus, the role of Central and Eastern Europe, especially that of Yugoslavia under Tito, is absent from the film. Pajović's text re-integrates the Yugoslav bloc into Two Meetings and a Funeral. While Pajović's text concludes with a hopeful view of the potential of the Non-Aligned Movement, Mohaiemen's images and superimposed quote from Tito express an ironic doubling back. Indira Gandhi's Indian coalition of 1971, while maneuvering for Bangladesh independence from Pakistan, encountered Tito's confident comment that such problems of “tribalism” were only happening in Asia. Yugoslavia had solved the “Balkan problem”– this was spoken confidently twenty years before Tito's nation would split apart during the Yugoslav Wars. The geopolitical struggles that Tito fails to see in 1971 are harbingers for the blind spots that would cause Non-Alignment's collapse.

The aim is to open the discussion of the concept of education and school that emerged as a result of the changes in information technologies and to provide insight into the future educational institutions. Firstly, the effects of changes in the world on educational institutions were discussed. The skills needed by the world were introduced and finally the 21st century Web 1.0, 2.0, 3.0, and 4.0 technologies, which are information sharing methods that enable data sharing over the internet. In the conclusion part, a school structure where principles such as personalized ways and methods of access to information, development of creativity, acquisition of necessary methods for reasoning, integration of information with systematic attitude is proposed. For the schools of the future, it has been concluded that the elements of education such as classrooms, technique, methods, tools, and materials, and the role of the teacher should be reconsidered, and the school should be designed in a way that individuals can establish their own knowledge sphere within the boundaries of the school buildings.

AbstractThe population dynamics of the desert locust, Schistocerca gregaria* (Forsk.), in Africa, the Middle East and Asia from 1966 to 1969 have been analysed to determine the causes of the beginning and the abrupt end of the plague of 1968. Evidence indicates that in 1966 there were no persistent sequences of breeding by gregarious populations, but in 1967 and early 1968 there were four sequences of breeding by initially solitary behaving locusts, each resulting in a substantial increase in numbers and density. These events led to a plague that ended by mid-1969.The threshold rainfall requirement for successful breeding, defined as an increase in numbers from mature adults of the parent generation to filial fledglings, has been related to the rainfall required for the germination of ephemerals and their growth to sizes that can provide food and shelter for hoppers throughout their development. It is suggested that the minimum quantity of rainfall required initially over a large area is 25 mm. This requirement is usually met in the summer breeding areas. Rainfall in the winter-spring breeding areas is more variable, and falls exceeding the threshold are most commonly associated with deep troughs in the mid- and upper-tropospheric westerly winds in winter and spring. A season in which many such troughs occur may be essential for plague development. It is also suggested that the timing of successive periods of rainfall allowing successful breeding is critical in determining the occurrence of upsurges.Control against non-gregarious infestations failed to contain the upsurge, but later control measures against hopper bands and swarms contributed to the plague decline. The most economical strategy for plague prevention might be one of upsurge elimination, that is to say control in selected areas against gregarious locusts only. The implications of adopting such a strategy are discussed.
