Roll Out

Network slicing is a powerful paradigm for network operators to support use cases with widely diverse requirements atop a common infrastructure. As 5G standards are completed, and commercial solutions mature, operators need to start thinking about how to integrate network slicing capabilities in their assets, so that customer-facing solutions can be made available in their portfolio. This integration is, however, not an easy task, due to the heterogeneity of assets that typically exist in carrier networks. In this regard, 5G commercial networks may consist of a number of domains, each with a different technological pace, and built out of products from multiple vendors, including legacy network devices and functions. These multi-technology, multi-vendor and brownfield features constitute a challenge for the operator, which is required to deploy and operate slices across all these domains in order to satisfy the end-to-end nature of the services hosted by these slices. In this context, the only realistic option for operators is to introduce slicing capabilities progressively, following a phased approach in their roll-out. The purpose of this paper is to precisely help designing this kind of plan, by means of a technology radar. The radar identifies a set of solutions enabling network slicing on the individual domains, and classifies these solutions into four rings, each corresponding to a different timeline: (i) as-is ring, covering today’s slicing solutions; (ii) deploy ring, corresponding to solutions available in the short term; (iii) test ring, considering medium-term solutions; and (iv) explore ring, with solutions expected in the long run. This classification is done based on the technical availability of the solutions, together with the foreseen market demands. The value of this radar lies in its ability to provide a complete view of the slicing landscape with one single snapshot, by linking solutions to information that operators may use for decision making in their individual go-to-market strategies.

Exercises programs that are customized and tailored according to the need of the individual is the focus of various international organizations. Today the concept of long and continuous form of exercises has seen a paradigm shift towards the concept of exercises as medicine where health care professional are focusing towards designing and prescribing exercises that fits the need of individual and that could be discontinued once the desired goals are achieved. Evidences in favor of tailored exercises programs have further strengthen this concept where various literatures have suggested that customized and tailored exercise programs does not only provides short term benefits but certainly found to be helpful in improving agility, cardiovascular fitness, lung compliance, weight management and improving social life in long run as well.

Hematological Changes

Hematological changes are commonly observed following prolonged exposure to hypoxia and bed rest. Typically, such responses have been reported as means and standard deviations, however, investigation into the responses of individuals is insufficient. Therefore, the present study retrospectively assessed individual variation in the hematological responses to severe inactivity (bed rest) and hypoxia. The data were derived from three-bed rest projects: two 10-d (LunHab project: 8 males; FemHab project: 12 females), and one 21-d (PlanHab project: 11 males). Each project comprised a normoxic bed rest (NBR; PIO2=133mmHg) and hypoxic bed rest (HBR; PIO2=91mmHg) intervention, where the subjects were confined in the Planica facility (Rateče, Slovenia). During the HBR intervention, subjects were exposed to normobaric hypoxia equivalent to an altitude of 4,000m. NBR and HBR interventions were conducted in a random order and separated by a washout period. Blood was drawn prior to (Pre), during, and post bed rest (R1, R2, R4) to analyze the individual variation in the responses of red blood cells (RBC), erythropoietin (EPO), and reticulocytes (Rct) to bed rest and hypoxia. No significant differences were found in the mean ∆(Pre-Post) values of EPO across projects (LunHab, FemHab, and PlanHab; p>0.05), however, female EPO responses to NBR (Range - 17.39, IQR – 12.97 mIU.ml−1) and HBR (Range – 49.00, IQR – 10.91 mIU.ml−1) were larger than males (LunHab NBR Range – 4.60, IQR – 2.03; HBR Range – 7.10, IQR – 2.78; PlanHab NBR Range – 7.23, IQR – 1.37; HBR Range – 9.72, IQR – 4.91 mIU.ml−1). Bed rest duration had no impact on the heterogeneity of EPO, Rct, and RBC responses (10-d v 21-d). The resultant hematological changes that occur during NBR and HBR are not proportional to the acute EPO response. The following cascade of hematological responses to NBR and HBR suggests that the source of variability in the present data is due to mechanisms related to hypoxia as opposed to inactivity alone. Studies investigating hematological changes should structure their study design to explore these mechanistic responses and elucidate the discord between the EPO response and hematological cascade to fully assess heterogeneity.

Long Term Impact

This article examines customers’ short-term attitudinal and long-term behavioral responses to service failures and recovery efforts. Our data from a tracking study of casual dining restaurants customers indicate that those who did not experience any failure were more satisfied than those who experienced successful recovery following a failure. The satisfactory recovery group, in turn, was more satisfied than customers who either did not complain or were not successfully recovered following their complaints. Importantly, the pattern of brand patronage over the medium and long run differed substantially from the short-term variation in satisfaction levels across the four customer groups. In the medium term, the brand visitation frequency for those who never experienced failure was similar to those of customers who were successfully recovered. The visitation frequencies of customers who did not complain or were not successfully recovered were lower. However, over the long run, the visitation pattern changed substantially, and those who never experienced failure had higher brand patronage frequency than all the three remaining groups that behaved relatively similarly. These results suggest that customers make a distinction between the qualities of the core service and the recovery effort. Although successful recovery temporarily compensates for core failure, its positive influence dissipates over time. In the longer term, customers’ complaining behavior and the firm’s recovery efforts matters less and customers’ brand patronage depends largely on whether or not they experienced core service failure. Nevertheless, firms can recover their investments in service recovery because of increased brand patronage in the medium term.

This article argues that an effective way to analyse the macroeconomic effects of business-to-business electronic commerce is to regard it as a decline in the cost of information to producers. Calculations based on input-output tables and the IMF's Multimod macroeconomic model show that current estimates of such savings translate into about a 5 per cent long-run increase in output in the major industrialised economies. In the medium term, although the deflationary effects of the shock would provide greater room to central banks to keep interest rates low, the simulation results also hint at short-term inflation risks if current demand outstrips supply in anticipation of higher future incomes.

This study estimates long run and short run association between inflation, government expenditure, and economic growth in Indonesia from 1981 to 2018. This study run diagnostic and specification test on time-series datasets in the model. This study employs Engel-Granger Cointegration Test and Error Correction Model (ECM) to estimate the long run and short run association in the model. This study further disaggregates government expenditure data in Indonesia into routine and development expenditure to analyse the individual and combined effect of the variable in the model. Result of the study suggested that the association between inflation and economic growth is negative, while the association between government expenditure and economic growth is positive. Moreover, routine expenditure has insignificant effect. Finally, ECM concluded that short-term adjustment in the model is less than one percent and specifically stable in all regression models.

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 chapter addresses the sustainability of debt. A systematic analysis based on the International Monetary Fund's (IMF) methodology to evaluate fiscal sustainability shows that Castile was able to service its debts in the long run. While liquidity was scarce during periods of intense warfare, years of relative peace brought large surpluses. The data collected from Castile's annual fiscal accounts produced new yearly series of revenue, military expenditure, short-term debt issues, and short-term debt service. The resulting database spans a full 31-year period—enough to employ modern quantitative techniques. This analysis provides strong evidence that Castile's fiscal position in the second half of the sixteenth century was on a solid footing. The chapter then assesses whether the events that led to major downturns in Castile's financial fortunes could have been anticipated.

The Impact

Until now the government and private sector have not been able to address the backlog of 13.5 million housing units for ownership status and 7.6 million units for residential status. The high price of land has led to the high price of the house so that low-income communities (MBR) is not able to reach out to make a home purchase. In addition to the high price of land, tax factors also contribute to the high price of the house. The government plans to issue a policy for the provision of tax incentives, ie abolish VAT on home-forming material transaction. This policy is expected to house prices become cheaper, so the demand for housing increases, and encourage the relevant sectors to intensify its role in the construction of houses. It is expected to replace the lost tax potential and increase incomes. Analysis of the impact of tax incentives housing to potential state revenue and an increase in people's income, especially in Papua province is using the table IO because in addition to looking at the role each sector can also see the impact on taxes (income tax 21 Pph 25 Pph, VAT), and incomes (wage). Although in the short-term impact is still small, but very rewarding in the long run. Keywords: Backlog, Gross Input, Primary Input, Intermediate Input

Psychological Capacities

Chapter 9 presents the idea that Literalism undermines current social and moral boundaries for moral status. Possession of psychological capacities, moral standing, and respectful treatment are a standard package deal. So either many more beings enjoy moral status than we now think, or the relative superiority of human moral status over other beings is diminished. It introduces the role of psychological ascriptions in drawing social and moral boundaries by examining dehumanization and anthropomorphism. It argues that in the short term Literalism does not motivate us to do more than make minor adjustments to current moral boundaries. We can distinguish the kinds of psychological capacities that matter for moral status from the kinds that best divide nature at its joints. In the long run, however, Literalism prompts us to reconsider the anthropocentric standards that govern current moral boundaries.
