A Perspective on Frugality in Growing Economies: Triggering a Virtuous Cycle between Consumption Propensity and Growth

The relationship between Growing economies have recovered from the global financial crisis faster than many developed economies and increased the consumption significantly over the past years. In light of the role of their consumption growth in global sustainability, this paper analyzes the decisive factors leading to a virtuous cycle between consumption propensity and investment in growing economies. An empirical analysis was conducted to identify the contributing factors to such a cycle in 40 countries. They could be divided into three economic groups by the marginal propensity to consume. The results suggest that growing economies suffer from an autarky cycle between consumption and GDP due to insufficient investment elasticity against consumption elasticity while advancing and advanced economies allow GDP growth to induce investment efficiently. A possible trigger for inducement of investment by growth in growing economies can be 'frugality'

A Transition from Consumption-Dependent Development to Investment-Driven Development: A Comparison of 40 Countries

Following up the contrasting behaviors that growing economies suffer from an autarky cycle between consumption and economic growth. Advancing and advanced economies allow GDP growth for inducing investments efficiently. An empirical analysis was conducted in 40 countries, inspired by Samuelson’s multiplier-accelerator model, to examine a mechanism for switching from an autarky cycle to an investment-inducing virtuous cycle. The results suggest that a correlation between consumption growth and investment intensity is crucial to enable a shift from an autarky cycle to a virtuous cycle. The transition dynamism of economic cycles in these countries in the last three decades is also analyzed

Catalyst Role of Government R&D Inducing Hybrid Management in Japan: Lessons for Emerging Economies

Japan has achieved conspicuous technology advancement and subsequent productivity increase by overcoming threats and constraints of sustainable development of economy and society. The achievement can be attributed to a sophisticated combination of industrial efforts and government stimulation. This paper analyzes the government role in inducing industrial strength in Japan. Empirical analyses were conducted focusing on technology driven development trajectory between Japan and the US over the last two decades. The results reveal that Japan incorporates sophisticated mechanism enabling the hybrid management of technology fusing indigenous strength and learning ability. While the combination of government and industry stagnated in the 1990s, a swell of reactivation emerged in the early 2000s. This can largely be attributed to revitalization of the mutual interaction between government and industry. Such a catalyst role of government R&D inducing the hybrid management demonstrated by Japan would provide a new insight in emerging economies

Dual Hybrid Management of Technology: Co-evolution with Growing Economies

Given the increasing significance of the co-evolution between advanced and growing economies for problem-solving innovation that aims at solving global critical issues, this paper attempts an empirical analysis to identify the optimal co-evolutionary trajectory, which could benefit both advanced and growing economies. While Japan has succeeded to develop the hybrid management of technology fusing indigenous strength and learning ability, it has revealed some limitations during the global simultaneous economic stagnation. The analysis suggests that the dual hybrid management of technology coevolving also with growing economies is decisive to the problem-solving innovation of the nation. This benefits nations in growing economies as well. This paper provides new insights into the problem-solving innovation, and also inducing strategy of growing economies for global sustainability

Measurements of the atmospheric neutrino flux by Super-Kamiokande: energy spectra, geomagnetic effects, and solar modulation

A comprehensive study on the atmospheric neutrino flux in the energy region from sub-GeV up to several TeV using the Super-Kamiokande water Cherenkov detector is presented in this paper. The energy and azimuthal spectra of the atmospheric ${\nu}_e+{\bar{\nu}}_e$ and ${\nu}_{\mu}+{\bar{\nu}}_{\mu}$ fluxes are measured. The energy spectra are obtained using an iterative unfolding method by combining various event topologies with differing energy responses. The azimuthal spectra depending on energy and zenith angle, and their modulation by geomagnetic effects, are also studied. A predicted east-west asymmetry is observed in both the ${\nu}_e$ and ${\nu}_{\mu}$ samples at 8.0 {\sigma} and 6.0 {\sigma} significance, respectively, and an indication that the asymmetry dipole angle changes depending on the zenith angle was seen at the 2.2 {\sigma} level. The measured energy and azimuthal spectra are consistent with the current flux models within the estimated systematic uncertainties. A study of the long-term correlation between the atmospheric neutrino flux and the solar magnetic activity cycle is also performed, and a weak indication of a correlation was seen at the 1.1 {\sigma} level, using SK I-IV data spanning a 20 year period. For particularly strong solar activity periods known as Forbush decreases, no theoretical prediction is available, but a deviation below the typical neutrino event rate is seen at the 2.4 {\sigma} level.Comment: 30 pages, 31 figure

Search for dinucleon decay into pions at Super-Kamiokande

A search for dinucleon decay into pions with the Super-Kamiokande detector has been performed with an exposure of 282.1 kiloton-years. Dinucleon decay is a process that violates baryon number by two units. We present the first search for dinucleon decay to pions in a large water Cherenkov detector. The modes $^{16}$O$(pp) \rightarrow$ $^{14}$C$\pi^{+}\pi^{+}$, $^{16}$O$(pn) \rightarrow$ $^{14}$N$\pi^{+}\pi^{0}$, and $^{16}$O$(nn) \rightarrow$ $^{14}$O$\pi^{0}\pi^{0}$ are investigated. No significant excess in the Super-Kamiokande data has been found, so a lower limit on the lifetime of the process per oxygen nucleus is determined. These limits are: $\tau_{pp\rightarrow\pi^{+}\pi^{+}} > 7.22 \times 10^{31}$ years, $\tau_{pn\rightarrow\pi^{+}\pi^{0}} > 1.70 \times 10^{32}$ years, and $\tau_{nn\rightarrow\pi^{0}\pi^{0}} > 4.04 \times 10^{32}$ years. The lower limits on each mode are about two orders of magnitude better than previous limits from searches for dinucleon decay in iron.Comment: 20 pages, 17 figures.

Solar Neutrino Measurements in Super-Kamiokande-IV

Upgraded electronics, improved water system dynamics, better calibration and analysis techniques allowed Super-Kamiokande-IV to clearly observe very low-energy 8B solar neutrino interactions, with recoil electron kinetic energies as low as 3.49 MeV. Super-Kamiokande-IV data-taking began in September of 2008; this paper includes data until February 2014, a total livetime of 1664 days. The measured solar neutrino flux is (2.308+-0.020(stat.) + 0.039-0.040(syst.)) x 106/(cm2sec) assuming no oscillations. The observed recoil electron energy spectrum is consistent with no distortions due to neutrino oscillations. An extended maximum likelihood fit to the amplitude of the expected solar zenith angle variation of the neutrino-electron elastic scattering rate in SK-IV results in a day/night asymmetry of (-3.6+-1.6(stat.)+-0.6(syst.))%. The SK-IV solar neutrino data determine the solar mixing angle as sin2 theta_12 = 0.327+0.026-0.031, all SK solar data (SK-I, SK-II, SK III and SKIV) measures this angle to be sin2 theta_12 = 0.334+0.027-0.023, the determined mass-squared splitting is Delta m2_21 = 4.8+1.5-0.8 x10-5 eV2.Comment: Submitted to Physical Review D; 23 pages, 40 figure
