Mobile Telephony in Emerging Markets: The Importance of Multi-Simming Customers

2015

Rapidly increasing sales of multi-SIM phones, mobile penetration rates above 100% and reported customer behavior all point to the fact that a signicant share of mobile customers in emerging markets tend to use more than one SIM card. A primary motive for this is to avoid making expensive o-net calls. We add a segment of exible prepaid customers, who choose to "multi-sim" in equilibrium, to the seminal model of competing telephone networks a la Laont,

Wear modelling in mild steel orthogonal cutting when using uncoated carbide tools

2007

Abstract Wear prediction in machining has been recently studied by FEM although the use of numerical methods for such applications is still a very challenging research issue. In fact, wear phenomenon involves many aspects related to process mechanics which require a very accurate modelling. In other words, only a very punctual code set-up can help the researchers in order to obtain consistent results in FE analysis. The high relative velocity between chip and tool requires effective material models as well as friction modelling at the interface. Moreover the prediction of temperature distribution is another critical task; in the paper some different procedures are discussed. Subsequently a …

Application of point-to-point matching algorithms for background correction in on-line liquid chromatography–Fourier transform infrared spectrometry …

2009

A new background correction method for the on-line coupling of gradient liquid chromatography and Fourier transform infrared spectrometry has been developed. It is based on the use of a point-to-point matching algorithm that compares the absorption spectra of the sample data set with those of a previously recorded reference data set in order to select an appropriate reference spectrum. The spectral range used for the point-to-point comparison is selected with minimal user-interaction, thus facilitating considerably the application of the whole method. The background correction method has been successfully tested on a chromatographic separation of four nitrophenols running acetonitrile (0.08…

Research on Evolution and the Global History of Pulp and Paper Industry: An Introduction

2012

The underlying assumption in the economic history of industries is the deterministic nature of the industry life cycle. That is, industries are assumed to follow a specific life cycle characterized by stages of nascence, growth, maturity and decline apparent in firm numbers, production volume and technological activity. This introduction gives an overview to the theme of this volume: the analysis of the birth, growth, maturity, and finally the decline of the mechanized pulp and paper industry from its inception in the early nineteenth century Europe to its current situation and future prospects in developing markets in Southern America and other regions.

Contractual Satisfaction: The Polish and Tanzanian Perspectives

2013

Purpose: Interfirm satisfaction has been studied at the aggregate level, which has limited use in terms of understanding specific dimensions. Contractual satisfaction relates to the specific level of analyzing interfirm satisfaction. This study contributes towards understanding contractual satisfaction and the contextual nature of the concept. To achieve the latter, two heterogeneous emerging markets were used (Poland and Tanzania). Methodology: The study was conducted in Poland and Tanzania, focusing on manufacturing firms. The sample included 201 Polish firms and 240 Tanzanian firms. Findings: The major findings suggest that ex ante costs and ex post specifications have a significant posi…

The Challenges Underlying Firm Revival and Resilience in the Post-COVID-19 Phase

2022

Covid-19 is an exogenous shock that has deeply modified the basic building blocks and the micro-mechanisms on which socio-economic systems and organizations rest. The vast majority of both factor markets and final markets have been significantly disrupted on a worldwide scale. As all factors that determine severe crises, the Covid-19 pandemic is a low probability and high impact shock which has significantly changed the environment in which firms operate (Grewal and Tansuhaj 2001, Hudecheck et al. 2020). Such changes have nonetheless been asymmetric, whilst they have menaced the survival of a huge number of firms and have brought to their knees many key industries, it has also ignited rapid…

A novel method to predict dark diversity using unconstrained ordination analysis

2019

[Questions] Species pools are the product of complex ecological and evolutionary mechanisms, operating over a range of spatial scales. Here, we focus on species absent from local sites but with the potential to establish within communities — known as dark diversity. Methods for estimating dark diversity are still being developed and need to be compared, as well as tested for the type, and amount, of reference data needed to calibrate these methods. [Location] South Bohemia (48°58′ N, 14°28′ E) and Železné Hory (49°52′ N, 15°34′ E), Czech Republic. [Method] We compared a widely accepted algorithm to estimate species pools (Beals smoothing index, based on species co-occurrence) against a nove…

The Interactions between COVID-19 Cases in the USA, the VIX Index and Major Stock Markets

2021

With this study, we aimed to determine (1) the effect of the daily new cases and deaths due to the COVID-19 pandemic in the United States on the CBOE volatility index (VIX index) and (2) the effect of the VIX index on the major stock markets during the early stage of the pandemic period. To do this, we collected and analysed the daily new cases and death numbers during the COVID-19 pandemic period in the United States and the country indexes of the USA (DJI), Germany (DAX), France (CAC40), England (FTSE100), Italy (MIB), China (SSEC) and Japan (Nikkei225) to determine the impact of the VIX index on the major stock markets. We then subjected this data to the Johansen co-integration test and …

Is There Real Freedom of School Choice?: An Analysis from a Study in Chile1

2018

Between 1981 and 1990, Chile began to implement an education reform based on school choice and a financing system through vouchers. In theory, the system ensures complete freedom of choice of school by families. This article attempts to identify the existence of factors that conditioned the enrollment process in different types of schools existing nowadays in the Chilean educational system, the largest quasi-market of Latin America. Results show a social stratification and separation by schools and indicate how geographical distance and social composition are the most critical factors for families when choosing a school.
