Leveraging Entrepreneurial Ambition and Innovation : A Global Perspective on Entrepreneurship, Competitiveness and Development

The study described in this report combines two unique datasets, the World Economic Forum’s Global Competitiveness Index data, which ranks the economic competitiveness of 144 economies, and Global Entrepreneurship Monitor’s assessment of entrepreneurial activity across 70 economies. Using five years of data from both sets, the study analyses a sample of 44 economies by first examining three aspects of entrepreneurial activity, then grouping economies into five types of entrepreneurial clusters, and finally developing a deeper understanding of each type of cluster. Lastly, the study delves into what policymaking best benefits the unique characteristics of different economies

Effects of an Online Visual Procedure on Task Completion, Time, and Attitude

Although substantial literature exists regarding learning with visuals, most consider text the primary channel with varying amounts of visuals explored as a secondary channel. This study considered the effectiveness of visuals-only procedural guides versus visuals plus added text, using visuals as the primary channel and using visuals developed from screen shots to eliminate the need to create a visual, stand-in vocabulary. There was no difference in the level of successful task completion between treatment groups. The time required to complete the task was measured and there were significant differences in the amount of time required by treatment group, age, and sex. Both treatment groups responded favorably to the procedures on a follow-up attitude questionnaire. Implications of the study and suggestions for further research are discussed.Yeshttps://us.sagepub.com/en-us/nam/manuscript-submission-guideline

Modification of Al Current Collector/Active Material Interface for Power Improvement of Electrochemical Capacitor Electrodes

This paper presents results about carbon nanofibers (CNFs) synthesis and their use as surface treatments for Al current collector for carbon electrochemical capacitors in organic electrolyte. CNFs have been successfully synthesized on a pretreated Al substrate; the pretreatment of Al consists of an etching followed by a carbonaceous sol-gel deposit. Performances of cells assembled with pretreated Al and pretreated Al coated by CNFs have been compared by using galvanostatic cycling measurements. Internal resistances as low as 0.4 Omega cm2 are obtained for cells using CNF-treated Al. The increase of the surface contact and interface conductivity between the Al and the active material are responsible for this internal resistance decrease. The capacitance obtained for the two cells is the same (95 F g–1 of activated carbon). Performances [both equivalent series resistance (ESR) and capacitance] are stable over 10 000 cycles, proving the great efficiency of surface treatments

The practices of apartheid as a war crime: a critical analysis

The human suffering caused by the political ideology of apartheid in South Africa during the Apartheid era (1948-1994) prompted worldwide condemnation and a variety of diplomatic and legal responses. Amongst these responses was the attempt to have apartheid recognised both as a crime against humanity in the 1973 Apartheid Convention as well as a war crime in Article 85(4)(c) of Additional Protocol I. This article examines the origins, nature and current status of the practices of apartheid as a war crime and its possible application to the Israeli-Palestinian conflict

Direct observation of active material concentration gradients and crystallinity breakdown in LiFePO4 electrodes during charge/discharge cycling of lithium batteries

The phase changes that occur during discharge of an electrode comprised of LiFePO4, carbon, and PTFE binder have been studied in lithium half cells by using X-ray diffraction measurements in reflection geometry. Differences in the state of charge between the front and the back of LiFePO4 electrodes have been visualized. By modifying the X-ray incident angle the depth of penetration of the X-ray beam into the electrode was altered, allowing for the examination of any concentration gradients that were present within the electrode. At high rates of discharge the electrode side facing the current collector underwent limited lithium insertion while the electrode as a whole underwent greater than 50% of discharge. This behavior is consistent with depletion at high rate of the lithium content of the electrolyte contained in the electrode pores. Increases in the diffraction peak widths indicated a breakdown of crystallinity within the active material during cycling even during the relatively short duration of these experiments, which can also be linked to cycling at high rate

Morel_Moreau_Morella. The Metamorphoses of Adolfo Bioy Casares Invention in a (Re) Animating Universe

Adolfo Bioy Casares short novel The Invention of Morel (La invención de Morel, 1940) envisioned the wish of human beings to define themselves through technology, indeed to reanimate the human as a technological double in an environment that gradually becomes virtual. This article develops the relationships connecting The Invention of Morel with three animating forms: the phantasmagoria, the automaton, and the machine-environment, to stress the privileged association they make between invention and (re)animation. With this purpose, the paper examines key contributions to our understanding of simulation and automata in the field of animation theory, such as Alan Cholodenko s Speculations on the Animation Automaton , but also Joubert-Laurencin s La lettre volante. Quatre essais sur le cinema d animation, which directly addresses Bioy Casares story as a metaphor of animated cinema. Sigmund Freud s psychoanalytical approach to the field of aesthetics in The Uncanny , and subsequent theories like Masahiro Mori s The Uncanny Valley , are also taken into consideration.Lorenzo Hernández, MC.
