description: Afin d'examiner les effets d'une réduction de cas sur les coûts par dossier et le taux de sortie, le conseil municipal a accordé trois postes supplémentaires à temps plein. Les services sociaux de la ville de Winterthur ont chargé le département du travail social de la ZHAW de fournir un accompagnement scientifique pour le projet pilote de septembre 2015 à février 2017. En mai 2015, trois anciens travailleurs sociaux du service de conseil social de Winterthur ont été tirés au sort pour former le groupe expérimental de septembre 2015 à février 2017. Ces trois travailleurs sociaux ont eu une charge maximale de 75 cas par poste à 100 % pendant la période expérimentale de 18 mois, tandis que les autres travailleurs sociaux ont eu une charge initiale de 124 cas (15 septembre 2015) à 143 cas (17 février 2017) par poste de travail à 100 %. Le groupe expérimental a cédé certains de ses cas précédents au hasard lors du lancement de l'expérience. Les nouveaux cas ont également été attribués de manière aléatoire. La présente étude a examiné si l'utilisation d'un plus grand nombre de ressources en matière de travail social pourrait être bénéfique et si des économies sur les coûts d'assistance sociale pouvaient être réalisées avec une charge de travail réduite. Si on calcule les coûts moyens des cas dans les deux groupes en comparaison, il apparaît que le groupe expérimental peut faire état d'une économie moyenne d'environ 1’452 Fr. par cas et par an. Si l'on considère ce montant sur le nombre total de 2'903 cas (pendant la phase expérimentale) de conseil à long terme, cela donne un total de 4'195’000 Fr. de potentiel de réduction des coûts pour la ville de Winterthur, si tous les travailleurs sociaux de l'aide à long terme travaillaient dans le même cadre avec un maximum de 75 cas par poste de travail à 100 %.

description: In the EU there is an increasing need for regulatory agencies to derive health based threshold limits based on human inhalation studies with airborne particles. A necessary prerequisite for such projects is the development of a suitable generator system to produce nanoparticle test aerosols for human whole-body inhalation studies. We decided to use a generator with flame-based heating of aqueous precursor solutions. Validation of the test system was done by generating zinc oxide (ZnO) nanoparticles with minimal contamination of trace gases, i.e., nitric oxides or carbon monoxide that could confound the effects seen in exposed subjects. ZnO was selected based on the uncertainties surrounding its health effects after exposure at the workplace. The generation process of the developed flame generator yields ZnO nanoparticles with monomodal size distribution and very good temporal stability. The maximum target exposure mass concentration of 2 mg/m3 ZnO, with a resulting median particle diameter of 57 nm, is attainable in our human exposure laboratory. The morphological examination shows typical agglomerates and aggregates formed by high temperature processes. Overall, the performed experiments confirm that a constant exposure can be provided for all subjects at all times. Copyright 2014 American Association for Aerosol Research

description: In this study, we describe systematic preparation of a series of aryl-substituted pyridine derivatives. The 1,5-dicarbonyls (3a–i) were prepared in the solvent-free conditions starting from chalcone derivatives (1a–i). The target compounds, 4-aryl-2-(thiophen-3-yl)-6,7-dihydro-5H-cyclopenta[b]-pyridine derivatives (5a–i), were synthesized by a cyclization reaction of the 1,5-dicarbonyls (3a–i) with ammonium acetate (NH4OAc) in acetic acid. The characterization of synthesized compounds was proved by elemental analyses, infrared, mass spectrometry, and 1H and 13C NMR spectroscopy. [Supplementary materials are available for this article.

description: The effect of varying seed rate and screening o f insecticides were done in Kulumsa Agricultural Research Center by sowing Yellow Dodolla mustard in year 2011. The experiments were laid-out in a randomized complete block design (RCBD) with four replications. Two rows o f lm length were used fo r sampling o f flea beetles and their damage. Yield was obtained from 1.5m x 2m area o f each plot and expressed in kg/ha. The six seed rates revealed no significant difference in mean number of flea beetles but the mean number o f damaged plants was found to be decreased from plots sown with the lowest to the highest seed rates fo r all phonological stages o f the crop. Productive plants and plant population reduction were maximum fo r plots o f the highest seed rate (10.8g) and minimum fo r the lowest (2.7g) seed rate. Maximum mean seed yield (1917.8kg/ha) was obtained from plots sown with seed rate of 5.4g (lOkg/ha). The higher rate of Carbaryl, Maiathion and the two rates o f Fenitrothion reduced significantly the mean number of flea beetles and the damage (P<0.05) they caused to the plant. Productive plants and yield (kg/ha) were higher fo r plots treated with higher rate o f Carbaryl, Maiathion and lower rate o f Fenitrothion. This study generally revealed that the recommended rate of seed rate and Fenitrothion at its recommended rate can be used in cabbage flea beetle management.

Year: 2023

description: Parasitic plants are widely distributed across all continents except Antarctica. The competition for food nutrients and water by these plants has harmful effect on the physiological activities of the host plant. A survey on the occurrence of parasitic plants was conducted in 2011 in and around Bonga and Yayu natural forests of southwestern Ethiopia. This study was aimed at determining the distribution of parasitic plants on economically and ecologically important trees species in the two forests. Foui" species of parasitic plants were recorded associated with ten host plants. Higher rate infection was observed in the fragmented forests located around homesteads and margin of the forests than in dense forests. Further geographical variation and percent of infection were evident
between the forests and host plants. For the first time, Coffea arabica was observed to be infected by Viscum congolense. This infection imparted negative effects on coffee bean production in Bonga forest. Similar infections were also recorded in several coffee shade trees. Therefore, future research works need to address forest situated in the lower administrative levels and analyze the impacts of parasitic plant in economically important tree species

description: The study was conducted for three consecutive years (2011/12 to 2013/14) at Debre Zeit and Chefe Donsa to generate information on the morph and age structure o f pea aphid population in lentil. The data were generated from pea aphid management trial on two lentil genotypes Alemaya and ILL7664. There were 12 plots per genotype and from each plot aphid sample was collected by beating the plant three times onto a counting board of 20cm x 39cm. Aphids dropped on the counting board were put in a labeled plastic bag, brought to laboratory and separated in to alate, adult apterae and nymphs. Morph and age composition were not affected
by lentil genotypes. Thus, the pattern of morph and age structure was similar on both genotypes in any one year and location. At Debre Zeit, depending on season and sampling date pea aphid population was composed of 0.0 to 10.0% alate, 6.6 to 34.4% adult apterae and 62.3 to 92.7% nymphs. The corresponding values for ILL7664 were 0.3 to 14.8%, 3.7 to 29.3%, and 68.9 to 92.9%. Similarly, at Chefe Donsa out of the total pea aphid population on Alemaya 0.0 to 10.2% were alate, 8.3 to 38.1% were adult apterae and 57.1 to 88.9% were nymphs. On ILL7664 the population constituted of 0.0 to 11.2% alate, 9.1 to 37.0% adult apterae and 59.3 to 89.9% nymphs. The presence o f larger proportion of nymph indicates either the population is at an increasing rate or the survival rate i.e. the number of nymphs reaching adult stage is low. Therefore, the generated information will enable to understand the population dynamics of pea aphid and helps to develop effective integrated pest management program.

description: Rate and frequency determination o f seed extracts of physic nut (Jatropha curcas) against Chilo partellus (Swinhoe) on maize at Melkassa was studied at the rates of 22.2,44.4, 66.7 and 88.6 kg per ha, and frequencies o f two times, three times and four times at weekly interval starting from two weeks after crop emergence. Stand count, lower leaf damage percent, and leaf damage score, larval density, percent dead larvae and grain yield were the parameters considered to evaluate the treatments. The result obtained clearly indicates that C. partellus infestation was significantly higher and lower in the highest and lowest rate, respectively with four times application. In conclusion, application o f seed powders o f Physic nut at the rate of 88.6 kg per/ha with four times application at weekly interval starting from two weeks after crop emergence was found to be effective in the control o f C. partellus on maize which could be recommended to be used by small scale maize producers in Ethiopia and beyond.

description: Survey was carried out to study the distribution, composition and economic importance of diseases and insect pests of castor and mulberry plants between 2009 and 2011 in some parts of Ethiopia. From the surveyed areas, insect pests and diseased plants were observed and distinguished at their station. In addition, sample pests and infected plant parts were taken and examined in Melkassa Agricultural Research Center. The result showed that Mealy bugs (Paracoccussp.), Scale insects (Aonidiella sp. and Coccus sp.), Semi looper (Achoea sp.), Common bugs (Acrosternum sp.), Jassids (Empoasca sp. and Eurymela sp.), Hairy caterpillar (Euproctis sp.), Stinkbug (Nezara sp.), and grass hoppers (Ornithacris sp.) were observed as insect pests on castor with different rate of infestation and damage level. Very high infestation and damage level were found from mealy bugs, scale insects and common bugs. The most widely distributed insect pests were common bugs, jassids and Semi looper which were recorded from most of the surveyed areas. Mulberry borer (Apriona sp.), common jassid (Eurymela sp.), soft scale insects (Pulvinaria sp.) were recorded as insect pests on mulberry plant. Among castor diseases Alternaria sp., Fusarium sp., Melampsora sp.. Cercospora sp. and Xanthomonas sp. were recorded. Incidence and severity were high when castor plant was infected with Alternaria sp., Cercospora sp. and Melampsora sp. All causal organisms of castor diseases were distributed in the surveyed areas. Among diseases Cercospora sp., Phyllactinia sp. (powdery mildew), and Pseudomonas sp. was found to infect mulberry cultivars. The major and widely distributed disease in mulberry was Cercospora sp.

description: Following the outbreak of a spider mite infestation on the main season of 2014 on
potato at Haramaya district, field surveys were undertaken in August 2014 and 2015.
The field surveys covered the districts Fedis, Grawa, Haramaya, Jarso, Kersa,
Kombolcha and Meta of eastern Ethiopia. The 2014 result revealed that the pest was
confined only in Haramaya district. A similar survey conducted in August 2015
revealed the geographic expansion of the pest to other areas of eastern Ethiopia, viz.,
Dire Dawa Administration, Kersa. Kombolcha and Fedis districts. The spider mite,
which is commonly known as red spider mite, was identified as Tetranychus utrtcae
Koch (Acari: Tetranychidae). This is the first record of the pest infesting potato
(Solatium tuberosum L.) in Ethiopia. In addition to potato, the pest infested tomato,
cucumber and other Solanaceous weeds growing within and around potato fields. It
was observed that the pest causes quantitative crop damage by sucking the plant fluids.
The pest develops very rapidly on potato plants causing quick leaf-fall and death of the
infested plants. Farmers were unable to manage the pest with the con\entional
agricultural pesticides available on the local markets. This preliminary field survey
warrants that the red spider mite would be a threat to potato production in Ethiopia
unless apt research efforts are made and management strategies are developed to fight
against this devastating pest.

High atom economy, good yield, simple procedure, no expensive column chromatography, shorter reaction time, and metal-free and mild reaction conditions are some of the important features of this protocol. The current methodology provides an alternative approach for not only highly substituted tetrahydropyridines (THPs) but also fully substituted tetrahydropyridines (FTHPs) in moderate to good yields. The plausible mechanism for the formation of THPs was greatly promoted by the H+ ion coming from acetic acid. [Supplementary materials are available for this article.

While the preparation of numerous functional groups has been efficiently demonstrated employing the Mitsunobu reaction, our methodology represents the first application of the Mitsunobu reaction for the construction of benzamides using benzoic acid and amine starting materials. Moreover, this synthetic transformation is believed to proceed via a nonclassical mechanism involving the existence of an acyloxyphosphonium ion.

description: In Ethiopia maize suffers serious postharvest losses in storage due to different factors
among which insect pests are the most important. To address this problem, Sasakawa
Global 2000 - Ethiopia (SG 2000) in collaboration with the International Maize and
Wheat Improvement Center (CIMMYT) introduced and demonstrated hermetically
sealed metal silo as maize grain storage device to farmers in Amhara, Oromia and
SNNP regions in a participatory approach. This study was conducted to evaluate the
performance of the technology at six months of storage and assess farmers’
perception on the technology in order to decide whether the technology can be
disseminated for wide scale use. Farmers reported that weevils and moths followed
by rodents were the major storage problems and cause much loss. Physical analysis
of samples revealed that the metal silo provided complete protection with only 0.6 %
weight loss while the control treatment (polypropylene bag) did not protect the maize
grain from infestation by storage insect pests leading to 5.2 % weight loss. After
evaluating the treatments farmers also unanimously concluded that the metal silo was
very effective in addition to its merits of avoiding chemical hazard, saving of money
and increasing income. As a result farmers showed interest in using the metal silo
technology. Metal silo technology can, therefore, help farmers safely store their
produce and is worth demonstrating and disseminating.

description: Microbial biological pest control agents such as entomopathogenic fungi (EPF) can
be an effective alternative for the control of sorghum chafer, Pachnoda interrupta,
an important pest in Ethiopia. Production of inoculums of high quality with
reasonable quantity on mass production substrates is important for its use as
mycoinsecticides. Three liquid phase media viz. sucrose /waste brewer’s yeast
(SWBY), molasses/yeast extract (MYE) and lennoux broth base (LB) were evaluated
for effects on mass production characteristics of three M. anisopliae isolates viz.
PPRC51, PPRC2 and IC69 using rice as a solid substrate in the diphasic mass
production technique. Effects of liquid media on shelf-life and virulence of the
isolates against P interrupta was also evaluated. Weight of spores/kg of rice
substrate, number of spores/g of spore powder and viability of spores varied
significantly across the three isolates (P<0.0001). There was no significant difference
among liquid phase media and their interactions with isolates (P > 0.05). The highest
weight of spores (119.72g/kg) was obtained from IC69 mass produced by using
MYE as a liquid phase medium. PPRC2 produced the highest number of spores
(4.57x1010 spores/g) when using LB as liquid phase medium. Using MYE as liquid
phase medium, the virulence of the three isolates of M. anisopliae did not vary
significantly. Using either of the liquid media does not significantly affect all the
quality variables for mass production, virulence and shelf life of the isolates selected
for control of P. interrupta. Therefore any of the liquid phase media can be used for
mass production of the selected isolates on rice without significantly affecting
virulence and shelf life.

description: Berberis is a genus o f many species of deciduous and evergreen shrubs. Two species
of Berberis are present in Africa, Berberis vulgaris in northwest Africa and B. holstii
in the mountains o f eastern and southern Africa. The presence of B. holstii in Ethiopia
is reported in a book o f Ethiopian and Eritrean flora; however, there is no information
indicating that the plant serves as an alternate host of wheat stem rust (Puccinia
graminis). Since 2009, Ambo Plant Protection Research Center has initiated studies
on distribution o f Barberry shrubs in the northern part o f the country and collection of
aeciospores from the shrub and inoculation of different small cereal crops to confirm
whether the aeciospores are function stem rust or not.To meet these objectives,
surveys were carried out in the northern part o f Ethiopia and identified 19 localities
where the shrub is grown. O f these, 12 were in north Shewa, three in Wello zones of
Amhara region and four in south Tigray zone. The shrub is habitat o f altitudes
ranging from 2500 to 3000 masl and grows on hilly and rocky land rich in black
organic soil. In north Shewa. the survey was carried out once in a month for the
whole year. Thus, aecial infections o f the plants were not observed from February to
June. In July, August and December, traces of aecia were noted, but from September
to November aecial infections were abundant. The aecial samples collected were
inoculated on seedlings of susceptible wheat, barley, rye and oat crops. Alter two
weeks of incubation o f aeciospores, stem rust (P. graminis) infections were recorded
on wheat, barley, rye and rarely on oat crops. P. graminis that infected wheat, barley
and rye have formae speciales tritici/secalis, while that of oat was formae speciale
avenae. Moreover, some of the stem rust pustules found on these seedlings were
inoculated on the sets of 20 wheat stem rust differential hosts and resulted in races
avirulent to all/majority of the Sr. genes. The study indicated that B. holstii is an
alternate host o f stem rust. This report is the first of its kind in Ethiopia and further
studies are recommended to determine the role of B. holstii in the epidemiology of
wheat rusts in Ethiopia.

Lesbians' right-to-choose, children's 'right-to-know'
Creators: name: Dempsey, Deborah
Publisher: name: Swinburne
Year: 2024

description: During the second wave of feminism many lesbians seeking pregnancy preferred to use anonymous donor insemination as a means of avoiding patriarchal interference in their families. In the years since, there has been greater interest in what is seen as the more child-friendly alternative: finding an identifiable sperm donor with whom the child can seek contact. In this chapter, I consider the relative influence of the Women’s Liberation ‘right-to-choose’ and the more recent ‘right-to-know drawing on the stories of three lesbian mothers: Trish Williams, Karen Bell and Gale Attard. Trish Williams, who conceived and gave birth to daughter Sarah in 1988, was a member of a Melbourne-based lesbian feminist self- insemination group. Trish was influenced by a lesbian separatist-inspired commitment to donor anonymity that became tempered by exposure to arguments in support of children’s right to know. By the time Karen Bell and Gabe Attard had their children in 2000, the ideologically inspired use of unidentifiable donors had all but disappeared among lesbian prospective parents. But the struggle to balance right-to-choose with right- to-know remains just as important. These women’s stories serve to illustrate the political and social shifts over the past twenty years between lesbians’ own sense of reproductive and familial autonomy, and their awareness of the significance of biological fathers to children’s understanding of family and identity.

description: The diastereoselective formation of δ-hydroxyalkyl butenolide oxindoles has been achieved via a vinylogous Mukaiyama aldol reaction. The reaction was performed using various (N-alkyl)isatins 1 with 2-(trimethylsilyloxy)furan 2 catalyzed by quinine in tetrahydrofuran (THF). The reaction proceeds rapidly and affords the corresponding 3-hydroxy-(5-oxo-2,5-dihydrofuran-2-yl)indolin-2-ones in good yields with high diastereoselectivities (anti/syn ratio up to 96:4).

description: Ethanol extracted three botanicals (Azadirachta mdtca. Chenopodium ambrosoides
& Maesa lanceolata) and diatomaceous earth (DA) were tested to evaluate their
effectiveness against maize weevil, Sitophilus zeamais M. They were applied at three
rates of 0.3, 0.4 and 0.5 ml/g per 250 g of grain and compared with untreated control,
ethanol treated control and Malathion super dust as a standard check. The study was
laid-out in completely randomized design with three replications. Data were
collected on cumulative adult mortality, median lethal concentration, median lethal
time, F| progeny emergency, and grain damage. The results revealed that, higher
mortality of S. zeamais was observed from ethanol extracts of C ambrosoides
(98.3% with LT50 of 1.13 days), A. indica (97.5% with LT50 of 1.26 days), and
diatomaceous earth (100% with LT50 of 1.33 days) at 0.5ml/g after 21 days of
exposure periods. Apart from the untreated and ethanol treated controls, the lowest
cumulative adult mortality of S. zeamais was recorded from extracts of M. lanceolata
(58.4% with LT50 of 17.62 days) at 0.3ml. The LC5(, indicated that C. ambrosoides
extracts (0.23g/250g of maize) was the most toxic at minimum concentration while
M. lanceolata extracts and diatomaceous earth (0.27g) was the least potent to weevil
at lower concentration. No F| progeny emerged from the grains treated with the
former three treatments similar to the standard chemical leading to no seed with hole,
no weight loss and maximum germination percentage (93.50- 95.2%). The study
demonstrated that the extracts and DE at their higher concentration/dosage can be
used as components of maize weevil integrated management option.

description: Excerpts from the report Introduction: This supplement is designed for use with the Poultry and Egg Situation, a report issued periodically by the Economic Research Service. It augments and replaces many of the historical series previously carried in the situation report. Most of these statistical series originate within the Statistical Reporting Service of USDA. A number of series were developed by other USDA agencies including the Economic Research Service, Consumer and Marketing Service, and Foreign Agricultural Service. Non-USDA agencies contributing series are the Bureau of the Census and the Bureau of Labor Statistics. A summary table containing data designed to keep the monthly statistics of this supplement up to date appears in the Poultry and Egg Situation, along with other special tables. Most tables in this supplement provide space for posting data through 1965. Since this publication mainly features information for the United States as a whole, users of poultry and egg statistics may wish to supplement this information with data from the following reports which contain annual data by States: (1) Chickens and Eggs--Farm Production, Cash Receipts, and Gross Income, and (2) Turkeys--Farm Production, Disposition, and Gross Income.

description: Field experiment was conducted in randomized block design in 2012 and 2013 on
the role of soil and water conservation terraces on managing Kutcrotennes and
Microtermes pest species o f termite using wooden baits between adjacent terraces in
Ghimbi district o f Western Ethiopia. The zero gradient terraces range from 5 m to 20
m in length. Some o f the terraces are said to be closed when the ends o f adjacent
terraces were connected by vertical right and left terraces. Ten wooden baits o f 10
cm diameter had been inserted in the holes dug in the ground for this purposes
between each of the terraces that was inspected by taking out five o f the baits
randomly at three months intervals. Terraces ionger than 15 m protected termite
damage and damage severity to the baits starting from six months after application o f
the treatments and significantly differed from the rest o f the treatments. In
conclusion, soil and water conservation terraces should be considered as one
component of integrated termite management especially in areas where multiple
species are involved in causing damage. Further investigation is also required on
lengths and widths o f level terraces as well as on the duration o f the effectiveness of
the terraces.

Year: 2020

description: In this paper, we discuss an assignment we developed whose goal was to “unsettle” settler consciousness and critically foster a grounded politics of location amongst our postsecondary students. We analyze some of the important and sundry risks of taking learning from the classroom to the land, focusing on some of the assignment’s assumptions, effects, contradictions and complications. Drawing upon Moten & Harney’s urging of a “studying with and for,” Stuart Hall’s “politics without guarantees,” and Leanne Simpson’s “land as pedagogy,”we present our experiment in teaching as an exciting opportunity for learning – one that though rooted in aspirations towards more decolonial presents in our classrooms, is still always also deeply implicated in who gets made as a subject with access to the goods and protections of the colonial present within and outside of the university.

Year: 2023

description: An experiment was conducted for three years (from 2013 to 2015) to determine the
critical period of weed control (CPWC) in soybean (Glycine max (L.) Merr.) at the
research farm of Assosa Agricultural Research Center in Assosa zone. Western
Ethiopia. CPWC is an estimate of a duration that weed control must be effective to
prevent weed interference from reducing yields or a time interval when it is essential
to maintain a weed free environment to prevent crop yield losses. The study included
two categories of treatments: WFO = weed interference season long (no weed control),
WF15, WF30, WF45, WF60, WF75, WF90 = weed free for 15, 30, 45, 60, 75 and 90
days after crop emergence (DACE), respectively; and WI0 = weed free season long
(no weed infestation), WII5, WI30, WI45, WI60, W175, WI90 = weed interference
for 15, 30, 45, 60, 75, and 90 DACE respectively. Seed yield and yield components of
soybean increased as the weed free period increased, and decreased as the weed
interference period increased. When weeds were allowed to compete with the soybean
for the whole growing season (WFO), the crop yield was reduced by 49.34%
compared to the whole season weed free treatment (WI0). Based on 20 % acceptable
yield loss (A Y L ) value model, results of this study revealed that the CPWC started at
15 DACE and ended at 60 DACE. Therefore, controlling weeds during this period,
possibly two weed removal operations at the beginning and end of the critical period,
is necessary to prevent a significant soybean yield loss.

description: The use of the Mitsunobu reaction for the synthesis of N,N-diethylbenzamides affords ortho-, meta-, and para-substituted benzamides containing both electron-donating and electron-withdrawing groups. While the preparation of numerous functional groups has been efficiently demonstrated employing the Mitsunobu reaction, our methodology represents the first application of the Mitsunobu reaction for the construction of benzamides using benzoic acid and amine starting materials. Moreover, this synthetic transformation is believed to proceed via a nonclassical mechanism involving the existence of an acyloxyphosphonium ion.

Corruption and Russia's transition to a market economy
Creators: name: Wells, Christian
Publisher: name: Swinburne
Year: 2024

description: This dissertation investigates Russia’s transition to a market economy and the high levels of corruption that accompanied the process. After some sixty years under Communism and a centrally planned economy, Russia began the transition to a market economy at the beginning of the 1990’s. After the dissolution of the USSR in 1991 a power vacuum emerged which was filled to a large extent by organised crime and corrupt government officials. High levels of corruption became a common feature of the transitional process and to this day Russia is still perceived to be one of the most corrupt countries in the world. The dissolution of the USSR in 1991 was followed by dramatic drops in Russian citizens standards of living, income and even life expectancy. The harsh climate of the early stages of the transition was characterised by mass unemployment and most Russian citizens living in poverty. However some segments of Russian society became extremely rich during the early stages of transition. This was illustrated by the increase in wealth disparity as those with the right connections to government, business and organised crime flourished while those who did not, found their standards of living decreasing and sliding further into poverty. This study will look at some of the reasons or factors contributing to the high levels of corruption in transitional Russia. Some of the contributory factors to be analysed are the inefficient and weak legal system, the large unregulated economy and the oligarchic networks controlling large portions of the Russian economy. To some degree the political and economic impact of corruption will also be analysed and assessed. The author has used material from texts, journal articles and organisational reports to generate an overall picture of the transitional experience of Russia and the high levels of corruption that have accompanied the process.
