Productive Development Partnership in Brazil

Brazil was one of the first countries to adopt significant health policies to better attend people with HIV. The integrated analysis of the high cost of medicines, public health, and access to medicines comprises an extremely complex task, and Productive Development Partnerships (PDP) was the mechanism used by the Brazilian government, with a view to technological development and training of national production complex. The PDP of atazanavir was formalized in late 2011, and the agreement includes the transfer of technology, manufacturing, and distribution of the drug. The PDP emerges as a solution found by the government to minimize the Ministry of Health drug spending and encourage the local production. However, one should not ignore that there are risks associated with regulatory barriers and problems in negotiations with the holders of technology. Thus, this chapter presents a case study of the successes the management information of the productive development partnerships in Brazil as a collaborative tool for global health.

EFFECT OF LOCAL HONEY PRODUCTION AREAS ON ITS CONTENT OF SOME HEAVY METALS

This study was conducted to estimate some heavy metals cadmium, lead, nickel and iron in 15 samples of Iraqi honey with 3 replicates for each sample which were collected from apiaries near potential contamination areas in five Iraqi governorates, including Baghdad, Karbala, Babylon, Diyala and Salah al-Din. The atomic absorption technique was used to estimate the concentrations of heavy metals, the results showed that there were significant differences at (P≤0.05) between the concentrations of these elements in the honey samples, the highest concentrations of cadmium 0.123 mg/kg were recorded in Baghdad, near the petrochemical production complex, lead 4.657 mg/kg and nickel 0.023 mg/kg in Babylon near the power plant, iron was 1.863 mg/kg in Karbala near the waste collection and incineration plant, and all the concentrations of cadmium and lead in the studied honey samples were higher than the acceptable limits set by the European Commission Regulation.

Just How They Drew It Up: How In-House Reporters Fit Themselves Into the Sports Media System

This paper explores how in-house sports reporters—those who write for team- and league-branded websites—locate themselves within the sports media production complex. It builds from perspectives on professionalism that view it as a dynamic process of defining boundaries and building relationships between systemic stakeholders. The interview data presented here find that in-house reporters accentuate professional similarities to beat reporters and use this identity to build unique roles in sports organizations’ corporate structures. This push to define themselves as a distinct job category within the constellation of sports media professions speaks to the active work occupational groups engage in, and is reshaping the media system. The paper argues for a broader reconsideration of professional definitions, actors, and relationships within the sports media system as digital technology and other changes have altered preexisting relationships.

Results of clinical trials of a trivalent vaccine for horses

We have developed a trivalent vaccine made from the SV/69 strain of the Rhinopneumonia virus (RHIV), the bacteria strains of Salmonella abortus equi BN-12 - the causative agent of Salmonella abortion and Streptococcus equi N-34 - the causative agent of the horse strangles. Preclinical laboratory studies of the immunogenicity of the vaccine in linear and outbred mice showed that the preparation protects against experimental infection with the Rhinopneumonia virus by 88.8%, from the causative agents of Salmonella abortion and horse strangles by 100%. There were carried out clinical trials of a trivalent inactivated vaccine with a centrifuge strain Bacillus subtilis TNP-3 as an immunomodulator in order to specifically prevent salmonella abortion, rhinopneumonia and horse strangles. Clinical trials were carried out on horses in the Central regions of Yakutia. The business output of foals was 50.2% in the republic. The business yield in immunized mares was 76,0 % and in unvaccinated mares only 38,0 % in a controlled production trial at the "Uyruye" agricultural production complex. Consequently, immunization of mares with trivalent vaccine increased the reproduction rate by 38,0 %. Results of extensive production tests on 2,568 heads of herd horses confirmed the data of preclinical laboratory studies of immunogenicity in linear and outbred mice. The trivalent vaccine against rhinopneumonia, salmonella abortion and horse strangles stimulates immunobiological reactivity, induces the synthesis of specific antibodies in high titers and increases the business yield of foals from 18,0 to 38,0 %. The vaccine is highly effective and can provide recovery of disadvantaged settlements.

ANTI-CRISIS MANAGEMENT OF THE COMPETITIVE ADVANTAGES OF THE FOOD INDUSTRY PRODUCTION COMPLEX UNDER THE CONDITIONS OF INNOVATIVE TRANSFORMATION

Разработана модель антикризисного управления конкурентными преимуществами предприятий производственной сферы пищевой промышленности, учитывающая взаимовлияние факторов внутреннего и внешнего контуров воздействий, определяющих характер и масштаб реструктуризационных изменений. The influence of the state of the Russian economy and the food industry on the solution of problems in strengthening the competitiveness of the domestic commodity producer is indicated. The accumulation of resource potential by industrial sectors is becoming the key in the implementation of restructuring and modernization transformations in the face of crisis processes and expanding constraints. The development of marketing networks presupposes differentiated management of resource adaptation to market challenges in the manufacturing sector, increasing investment in the production and technological base of industries and accumulating the innovative and creative potential of human resources for its implementation in innovative solutions. It is proposed to build a restructuring loop, forming an anti-crisis component as a decompensator of crisis manifestations in the economic space and as a tool for weakening the manifestation of marketing-behavioral myopathy in the business environment. The resource deflector is configured to accumulate resources for various purposes and provides for their involvement in the processes of marketing mimicry in the development of projects for innovative transformations. A model of anti-crisis management of the competitive advantages of enterprises in the production sector of the food industry has been developed, taking into account the mutual influence of factors of the internal and external contours of impacts that determine the nature and scale of restructuring changes.
