Ways To Improve The Use Of Fiscal Policy To Reduce Poverty
We all know that today in the regions of the Republic, especially in rural areas, the majority of the population does not have a sufficient source of income. As in other parts of the world, Uzbekistan is poor. The country is implementing short-term and long-term strategic measures to reduce poverty. Shortterm measures are mainly aimed at eliminating the risk of the population moving from poverty to poverty. This article outlines fiscal policy priorities and implementation strategies for poverty reduction
Hero-making as ontological security practice: Tajikistan's identity politics and relations with Uzbekistan
Remembering national heroes is one of the most important aspects
of the politics of national identity. Due to their exemplary
lives and deeds, the national heroes get portrayed as the role
models for the nation. How do states choose the heroes? What are
the ‘selection criteria’? What is the role of commemorating
the heroes in defining the relations between the national
‘self’ and ‘other’? Using the case of the ‘Heroes of
Tajikistan’ and this nation’s problematic relations with
neighbouring Uzbekistan, this thesis attempts to find the answers
to these questions. In doing so, it relies on the
poststructuralist theories of IR. The study reveals that the
discursive construction of the national ‘self’ and
‘other’ through commemorating the ‘Heroes of Tajikistan’
is a correlative of Uzbekistan’s threatening behaviour in
relations with Tajikistan. In other words, remembering the heroes
in particular, and the identity politics in general, are not the
simple matters of domestic affairs, but rather can be the crucial
factors in studying international relations.
As this research revealed, the national identity discourses in
Tajikistan honour the ‘Heroes’ for their leadership in
achieving national independence from Uzbekistan in the 1920s
(Makhsum and Shotemur), and defending the Tajik language and
literary traditions from the discriminatory attitude of the Uzbek
nationalists in the late 1920s (Aini),as well as writing the
history of Tajiks throughout the Soviet period in a way that
represents Tajiks as the indigenous people of Central Asia and
Uzbeks as the occupants (Ghafurov). Uzbekistan’s interference
in the Tajik civil war (1992-1997) and its hostile position
towards the construction of the Roghun hydroelectric power
station in Tajikistan (since 2004) triggered the negative
memories about the traditional Uzbek ‘other.’ At the same due
to the predominance of the narratives about the traditionally
negative image of Uzbeks, the behaviour of Uzbekistan in the
post-Soviet period appears as a self-fulfilling prophecy. In the
light of ever-growing Tajik-Uzbek tension, literary, academic and
journalistic discourses in Tajikistan portray the President of
Tajikistan Emomali Rahmon, another officially recognised ‘Hero
of Tajikistan’, as continuing the struggle of the past heroes
against Uzbeks
Features of Construction of Systems of Railway Automatics and Telemechanics at the Organization of High-Speed Traffic in the Republic of Uzbekistan
AbstractThe most effective way to intensify the work of railway transport, improve the use of its main complex and costly technical means of transportation process management automation is using complex systems of interval control of train traffic and ensure its security. In the Republic of Uzbekistan decided to modernize its railways, where the priority is to increase the speed of passenger trains. A number of activities were undertaken to ensure the safety of high-speed trains such as the strengthening of railway tracks, update the dimensions of buildings, changing the configuration of the switches. In some areas, replaced antiquated systems of interval train traffic management with focus on devices automatic locomotive signaling
Evaluation of the effectiveness of blood-drop agglutination test for chicken tuberculosis diagnosis
Due to the increased role of opportunistic infections, mycobacterioses, parasitocenoses, etc. the detectability of nonspecific reactions to PPD-tuberculin has sharply increased, which makes it difficult to make a diagnosis and brings laboratory test methods to the fore. The aim of the study was to determine practical significance of blood-drop agglutination test in comparison with allergy test, and frequency of avian tuberculosis lesions on internal organs. For comparative assessment of these techniques 4,086 chickens were tested, including 2,000 young chicks aged 6–9 months and 2,086 adult poultry. In order to compare the results of allergy and serological tests, necropsy was performed for reacting chickens, identified using blood-drop agglutination test and demonstrating positive results using both methods. Low effectiveness of the allergy test in comparison with the serological test was established. The blood-drop agglutination test made it possible to additionally identify 311 adult chickens seropositive for tuberculosis in poultry farms. The effectiveness of this serological method in young birds and poor matching of results in comparison with an allergy test have been shown. The necropsy findings confirmed the practical significance of the serological test; generalized tuberculosis process was noted in all birds positively reacting in blood-drop agglutination test. The dependence of internal organ lesions on poultry-keeping conditions was determined in tuberculosis-affected farms in the autumn and spring periods. Internal organ lesions were found in 835 birds out of 1,072 tested poultry. In the autumn period the intestines were affected in most cases (57.2%), lung lesions were found in the least cases (8.2%), and in the spring period tuberculosis lesions were more often detected in the lungs (43.8%), less often in the intestines (35.5%). In the winter period, the morbidity predominantly occurs due to dust infection, and in summer, birds become infected via alimentary route, which explains the results obtained. The identification of a significantly larger number of diseased chickens, both in advanced form and at an early stage, makes it possible to recommend a blood-drop agglutination test for the diagnosis of tuberculosis. The involvement of internal organs directly depends on the poultry keeping system and should be taken into account when veterinary and sanitary measures are performed
Nontuberculous mycobacterium occurrence in biological material and environmental samples covered by epidemiological surveillance in the Republic of Dagestan
An investigation for causes of tuberculosis occurrence and persistence on farms, as well as of continuous presence of tuberculin reactor animals on tuberculosis-free farms impeding allergy diagnosis revealed that the major cause is the persistence of pathogenic and nontuberculous acid-fast mycobacteria in the environment. To determine the occurrence of typical and atypical mycobacteria in samples covered by epidemiological surveillance, 222 biological material samples from cattle, 248 environmental samples (manure, soil, water from different sources, feedstuffs), 44 milk samples from tuberculosis-affected farms, 20 vaginal discharge samples from endometritis-affected cows and 405 sputum samples from tuberculosis-affected humans were tested. Isolation and identification were performed in accordance with the guidelines. Thirty-nine cultures were isolated from the pathological material; of these, 7 (17.9%) were identified as Mycobacterium bovis and 32 (82.1%) were identified as atypical mycobacteria. Among nontuberculous mycobacterium cultures, 16 (50.0%) were classified as belonging to group II, 2 (6.2%) – as belonging to group III and 14 (43.8%) – as belonging to group IV according to the Runyon classification. The following species were found to be predominant: group II – Mycobacterium scrofulaceum and Mycobacterium gordonae (scotochromogenous), group IV – Mycobacterium smegmatis and Mycobacterium fortuitum (rapidly growing). No mycobacteria were detected in milk samples and vaginal discharge samples from tuberculin reactor cows. From 405 sputum samples from tuberculosis-affected humans, 64 (15.8%) cultures were isolated, of which 55 (85.9%) were classified as Mycobacterium tuberculosis, 9 (14.1%) – as Mycobacterium bovis. Out of 248 environmental samples tested, mycobacteria were detected in 65 (26.2%) samples, of which 58 (89.2%) were atypical mycobacteria of groups II, III and IV; Mycobacterium bovis was isolated from 7 (10.8%) samples (soil and manure). The attempts to isolate Mycobacterium tuberculosis failed. The tests demonstrated the wide spread of nontuberculous acid-fast mycobacteria in the environment irrespective of the altitudinal zone. These findings constitute a basis for further monitoring of mycobacterium circulation in the environment in the Republic of Dagestan with a view of optimizing preventive measures
Conical decomposition and vector lattices with respect to several preorders
The decomposition set-valued mapping in a Banach space E with cones K i,i = 1,..., n describes all decompositions of a given element on addends, such that addend i belongs to the i-th cone. We examine the decomposition mapping and its dual. We study conditions that provide the additivity of the decomposition mapping. For this purpose we introduce and study the Riesz interpolation property and lattice properties of spaces with respect to several preorders. The notion of 2-vector lattice is introduced and studied. Theorems that establish the relationship between the Riesz interpolation property and lattice properties of the dual spaces are given.C
