In Bangladesh, Adivasi, the indigenous people are of the poorest sections of the society due to their vulnerable    livelihoods with lack of resources. Cage based fish fingerling production (CBFFP) was promoted with Adivasi households in the north-east and north-west regions of Bangladesh. A structured questionnaire based survey was    conducted with a sample size of 150 CBFFP adopting households to assess the livelihood impacts of CBFFP on the    Adivasi households. Geographically, the study represents Sherpur and Netrakona districts from north-east and    Dinajpur, Rangpur, and Joypurhat districts from north-west regions of Bangladesh. In terms of socio-economic    characteristics, the average household size of Adivasi households was 4.21± 1.28 with day labour (40%) based    primary occupation. Majority (64%) of households heads were found illiterate and the remaining with low level    education attainment. Most of the Adivasi households depended on a single person’s (household head) income. The    average size of ponds in which the cages were set was about 1.2±1.4 hectare with the depth of 1.5-3 m. The cage    provided with Adivasi farmer was of 1 m3 in size and made of locally available materials, mainly bamboo made frame,    net and plastic bottles as floats. The average cost of a cage construction was about BDT 400±85.2 (USD 5.71±1.2).    The fry of tilapia (Oreochromis niloticus), silver carp (Hypophthalmichthys molitrix), rui (Labeo rohita), mrigal    (Cirrhinus cirrhosus), bighead carp (Aristichthys nobilis), common carp (Cyprinus carpio), Thai sarpunti (Barbonymus    gonionotus) were stocked in the cages for fingerling production. The average stocking density was about 875±507    fry/cage (about 3.4cm in length). In average, fingerling production cost was about BDT 268±129.2/cage (USD    3.83±1.8/cage) and selling value was about BDT 431±509.1/cage (USD 6.16±7.2/cage). The major impacts of    CBFFP include increased household level income (1.7%), use of this income to buy livestock for rearing further.    Moreover, CBFFP impacted positively on other aspects of livelihoods such as purchasing food in lean period, saving    money and paying credit. The large size fingerlings produced in the cages were used as food fish for household level    consumption. The main constrains of Adivasi households to adopt CBFFP were poaching of fish from cages and    variable access to ponds for cage installation.   DOI: http://dx.doi.org/10.3329/jbau.v9i2.11047     J.

It is shown that the leading role in the aquaculture of Iraq belongs to Cyprinids, which account for over 80 % of all fish farming production. The most widespread in the country are four main world species of carp aquaculture: common carp (Cyprinus carpio), grass carp (Ctenopharyngodon idella), silver carp (Hypophthalmichthys molitrix) and bighead carp (Aristichthys nobilis). Basically, the traditional technology of growing Cyprinids in ponds is used, which includes the main fish farming processes: care of broodstock to prepare them for spawning, collecting eggs and milt, eggs fertilization and incubation of embryos, raising juveniles and marketable fish. Currently, there are about 2 thousand private fish farms, which have ponds of various sizes from 4 to 100 hectares. Cultivation of Cyprinids in Iraq is carried out mainly by extensive methods: the use of the natural food base of reservoirs with low fish stocking density in polyculture. The fish productivity of ponds varies greatly in different fish farms from 1,5 to 6 t/ha, which is due to economic reasons. The data on changes in the temperature of pond water during the year and hydrochemical indicators are given, which shows favorable conditions for Cyprinids rearing. Information on the use of compound feeds for growing carp in ponds is provided, and data on the composition and nutritional value of the feed used. The fish culture indicators for the main biotechnical processes of the rearing of four Cyprinid species in Iraq are described in detail. In the conclusion, it is indicated that for the effective development of aquaculture in Iraq, government support is needed in the form of a developed long-term program and legislative acts.

Geology of Greenland Survey Bulletin, 186, 35-41. https://doi.org/10.34194/ggub.v186.5213 _______________ Mapping and regional geological studies in northern Greenland were carried out during the project Kane Basin 1999 (see Dawes et al. 2000, this volume). During ore geological studies in Washington Land by one of us (B.T.), finds of erratics of banded iron formation (BIF) directed special attention to the till, glaciofluvial and fluvial sediments. This led to the discovery that in certain parts of Daugaard-Jensen Land and Washington Land volcanic rocks form a common component of the surficial deposits, with particularly colourful, red porphyries catching the eye. The presence of BIF is interesting but not altogether unexpected since BIF erratics have been reported from southern Hall Land just to the north-east (Kelly & Bennike 1992) and such rocks crop out in the Precambrian shield of North-West Greenland to the south (Fig. 1; Dawes 1991). On the other hand, the presence of volcanic erratics was unexpected and stimulated the work reported on here.

Set Up

Early in 1963 much of the land occupied by the Roman building at Fishbourne was purchased by Mr. I. D. Margary, M.A., F.S.A., and was given to the Sussex Archaeological Trust. The Fishbourne Committee of the trust was set up to administer the future of the site. The third season's excavation, carried out at the desire of this committee, was again organized by the Chichester Civic Society.1 About fifty volunteers a day were employed from 24th July to 3rd September. Excavation concentrated upon three main areas; the orchard south of the east wing excavated in 1962, the west end of the north wing, and the west wing. In addition, trial trenches were dug at the north-east and north-west extremities of the building and in the area to the north of the north wing. The work of supervision was carried out by Miss F. Pierce, M.A., Mr. B. Morley, Mr. A. B. Norton, B.A., and Mr. J. P. Wild, B.A. Photography was organized by Mr. D. B. Baker and Mrs. F. A. Cunliffe took charge of the pottery and finds.

Solar Influence

In this paper the author investigates the periodical variations of the winds, rain and temperature, corresponding to the conditions of the moon’s declination, in a manner similar to that he has already followed in the case of the barometrical variations, on a period of years extending from 1815 to 1832 inclusive. In each case he gives tables of the average quantities for each week, at the middle of which the moon is in the equator, or else has either attained its maximum north or south declination. He thus finds that a north-east wind is most promoted by the constant solar influence which causes it, when the moon is about the equator, going from north to south; that a south-east wind, in like manner, prevails most when the moon is proceeding to acquire a southern declination ; that winds from the south and west blow more when the moon is in her mean degrees of declination, going either way, than with a full north or south declination ; and that a north-west wind, the common summer and fair weather wind of the climate, affects, in like manner, the mean declination, in either direction, in preference to the north or south, and most when the moon is coming north. He finds the average annual depth of rain, falling in the neighbourhood of London, is 25’17 inches.

Academic Review

Looking at two smaller-scale systemic school improvement projects implemented in selected district circuits in the North West and Eastern Cape by partnerships between government, JET Education Services, and private sector organisations, this book captures and reflects on the experiences of the practitioners involved. The Systemic School Improvement Model developed by JET to address an identified range of interconnected challenges at district, school, classroom and household level, is made up of seven components. In reflecting on what worked and what did not in the implementation of these different components, the different chapters set out some of the practical lessons learnt, which could be used to improve the design and implementation of similar education improvement projects. Many of the lessons in this field that remain under-recorded to date relate to the step-by-step processes followed, the relationship dynamics encountered at different levels of the education system, and the local realities confronting schools and districts in South Africa's rural areas. Drawing on field data that is often not available to researchers, the book endeavours to address this gap and record these lessons. It is not intended to provide an academic review of the systemic school improvement projects. It is presented rather to offer other development practitioners working to improve the quality of education in South African schools, an understanding of some of the real practical and logistical challenges that arise and how these may be resolved to take further school improvement projects forward at a wider district, provincial and national scale.

The Cyclopean Terrace Building lies to the north-west of the Lion Gate on the northern end of the Panagia Ridge and faces almost due west across the valley of the Kephissos and modern main road from Corinth to Argos. It lies just below the 200 m. contour line, and one terrace below the houses excavated in 1950–51 by Dr. Papadimitriou and Mr. Petsas to the east at the same end of the ridge. The area contains a complex of buildings, both successive and contemporary, and in view of the discovery of structures both to the south-west and, by the Greek Archaeological Service, to the north-east it is likely that this whole slope was covered by a portion of the outer town of Mycenae. This report will deal only with the structure to which the name Cyclopean Terrace Building was originally given, the so-called ‘North Megaron’, supported by the heavy main terrace wall.The excavation of this structure was begun in 1923. The main terrace wall was cleared and two L.H. IIIC burials discovered in the top of the fill in the south room. In 1950 it was decided to attempt to clear this building entirely in an endeavour to find out its date and purpose. The clearing was not, however, substantially completed until the close of the 1953 excavation season, and this report presents the available evidence for the date as determined by the pottery found beneath the building; the purpose is still a matter for study, though various tentative conclusions can be put forward.

Causative Factors

In the Mississippi River Basin of North America, invasive bigheaded carp (silver carpHypophthalmichthys molitrixand bighead carpH. nobilis, also referred to as Asian carp) have spread rapidly over the past several decades. In the Illinois River, an important tributary of the Upper Mississippi River, reproduction appears to be sporadic and frequently unsuccessful, yet bigheaded carp densities in this river are among the highest recorded on the continent. Understanding the causative factors behind erratic recruitment in this commercially-harvested invasive species is important for both limiting their spread and managing their harvest. We analyzed weekly catch records from 15 years of a standardized monitoring program to document the emergence of age-0 bigheaded carp in relation to environmental conditions. The appearance of age-0 fish was generally linked to hydrographic attributes, which probably serve as a cue for spawning. However, we found profound differences in the number of age-0 fish among years, which varied by as much as five orders of magnitude in successive years. The strong link between summer flooding and age-0 fish production we observed emphasizes the importance of understanding the hydrologic context in which sustained invasions occur. Despite evidence of sporadic recruitment, bigheaded carp populations in the Illinois River appear to be consistent or increasing because of particularly strong, episodic year classes.

The study explores the spatial patterns of poverty in Pakistan through two dimensions: asset accumulation and basic needs. For this purpose Pakistan Standard of Living Measurement 08-09 is employed to construct an Asset Index and a Basic Needs index, at a district level, through the use of household level indicators. The study finds a clear north south divide, with particular concentration of better off districts in the north east of the country. Additionally, regression analysis is carried out to help identify the macro level factors contributing towards the observed pattern. Results reveal infrastructural and industrial development to be significant factors behind a district‘s well-being. This indicates that public policy directed towards developing deprived districts should be cantered on these factors, specifically expanding road networks, and incentives for industrial development in those districts.
