New Challenges

China's socioeconomic accumulation in the last 30 years has been probably one of the most outstanding global developments and has resulted in massive new challenges for core and periphery countries. The article examines how China's rapid and massive integration to the world market has posed new challenges for countries such as Mexico - and most of Latin America - as a result of China's successful exportoriented industrialization. China's accumulation and global integration process does, however, not only question and challenges the export-possibilities in the periphery, but also the global inability to provide energy in the medium term.

Stimulation Of

In 2019, a textbook “Macroeconomics” was published in London, on the pages of which the authors presented a new monetary doctrine — Modern Monetary Theory, MMT, — an unorthodox concept based on the postulates of Post-Keynesianism, New Institutionalism, and the theory of Marxism. The attitude to this scientific concept in the scientific community is ambiguous. A smaller part of scientists actively support this doctrine, which is directly related to state monetary and fiscal stimulation of full employment, public debt servicing and economic growth. Others, the majority of economists, on the contrary, strongly criticize MMT, arguing that the new theory hides simple left-wing populism, designed for a temporary and short-term effect. This article considers the origins and the main provisions of MMT, its discussions with the mainstream, criticism of the basic tenets of MMT, and also assesses possible prospects for the development of MMT in the medium term.

This study aims to explore the factors of the implementation of Midterm-term Change Project proposed by alumni of Leadership Development Program (Diklatpim) Level held in 2017 in the Riau Province. Data was collected using interview technique and review of related documents. The informants included three parties namely the alumni as the owner of the change project, the alumni superior as the mentor and organizer of the Training. The results showed, from the perspective of implementation, there were internal factors (low willingness, seriousness and motivation, as well as alumni communication with limited work teams) and external (unavailability of IT staff, lack of support for infrastructure and budget facilities, inequality of perception between participants and stakeholders to supporting data, as well as the lack of direct attention of superiors as mentors) which is the cause of the suboptimal implementation of medium-term change projects. This research contributes to efforts to improve the implementation of medium- term change projects through an understanding of the factors that cause the low level of implementation of the project term change in 2017 Riau Province Diklatpim IV alumni.Keywords: leadership development, change project, training evaluation, Riau.

ABSTRACT Activities of various hydrolases and dehydrogenases were studied during the formation, development and involution of cyclic corpora lutea and in the corpora lutea of early pregnancy. At 24 hours postovulation the luteal cells, whether of granulosal or thecal origin, contained demonstrable levels of Δ5-3β-hydroxysteroid dehydrogenase and the NADP and NADPH2 diaphorases. During the period of proliferation and cellular growth, enzymic activities in the luteal cells were moderate at first, and then increased. In the mature corpus luteum, activities of the dehydrogenases occurred in all luteal cells but were most intense in the large polymorphic luteal cells. Activities of hydrolytic enzymes, low in the immediate postovulatory period, increased with the development of the vascular system. Enzymic characteristics of corpora lutea of gestation were similar to those of cyclic corpora, except for phosphorylase activity which was observed in luteal cells in gestational corpora, but confined to the vascular walls in cyclic corpora. No increase in activities of 17β- and 20β-hydroxysteroid dehydrogenases (above those seen in pre-ovulatory follicles) were observed after incubation of sections of either mature cyclic or gestational corpora. Involution of cyclic corpora lutea began with degenerative changes in the blood vessels: pyknosis of the endothelial cell nuclei and a sudden decline in activities of hydrolytic enzymes in the vascular walls. Subsequently, the luteal cells showed a sharp decrease in activities of the dehydrogenases as well as other signs of regressive change. The cytochemical findings are discussed in relation to biochemical observations on steroid synthesis by the bovine corpus luteum.

<p><b>Objectives:</b> Despite increasing recognition that off-pump coronary artery bypass surgery and sequential grafting strategy individually are associated with improved outcomes, concerns persist regarding the safety and efficacy of combining these 2 techniques. We compared in-hospital and midterm outcomes for off-pump multivessel sequential and conventional coronary artery bypass grafting.</p><p><b>Methods:</b> From September 1998 to September 2008, 689 consecutive patients received off-pump multivessel sequential coronary artery bypass grafting performed by a single surgeon. These patients were propensity matched to 689 patients who underwent off-pump coronary artery bypass grafting without sequential anastomoses. A retrospective analysis of prospectively collected perioperative data was performed. In addition, medical notes and charts of all the study patients were reviewed. The mean duration of follow-up was 5.1 � 2.0 years.</p><p><b>Results:</b> The major in-hospital clinical outcomes in the sequential and control groups were found to be similar. After adjusting for clinical covariates, sequential grafting was not an independent predictor of in-hospital adverse events (odds ratio [OR], 1.18; 95% confidence interval [CI], 0.86-1.50; <i>P</i> = .31), medium-term mortality (hazard ratio [HR], 1.26; 95% CI, 1.06-1.32; <i>P</i> = .92), and readmission to hospital (HR, 1.12; 95% CI, 0.96-1.20; <i>P</i> = .80). Sequential grafting was an independent predictor of receiving more than 3 distal anastomoses (OR, 7.46; 95% CI, 4.27-11.45; <i>P</i> < .0001). Risk-adjusted survival was 89% for sequential grafting patients and 88% for conventional grafting patients (<i>P</i> = .96) during the medium-term follow-up.</p><p><b>Conclusion:</b> Our analysis confirms the short- and midterm safety and efficacy of off-pump sequential coronary artery bypass grafting.</p>
