Improving demand forecasting accuracy using nonlinear programming software

2006

We address the problem of forecasting real time series with a proportion of zero values and a great variability among the nonzero values. In order to calculate forecasts for a time series, the model coefficients must be estimated. The appropriate choice of values for the smoothing parameters in exponential smoothing methods relies on the minimization of the fitting errors of historical data. We adapt the generalized Holt–Winters formulation so that it can consider the starting values of the local components of level, trend and seasonality as decision variables of the nonlinear programming problem associated with this forecasting procedure. A spreadsheet model is used to solve the problems o…

Do firms benefit from interactions with public research organisations beyond innovation? An analysis of small firms

2021

Abstract In this paper we argue that there is an extensive number of studies examining how firms obtain new products from their interactions with scientific agents, but other type of benefits has been overlooked. Specifically, we add to previous literature by considering not only product innovation, but also exploratory (long-term) and exploitative (short-term) results. We administer a tailored survey to firms collaborating with the Spanish National Research Council (CSIC) and data was completed with secondary sources. Results based on a sample of 756 firms suggest that firms consider all types of result as moderately important to them. Moreover, we observe that small firms report higher be…

Zooming into firm’s location, capabilities and innovation performance: does agglomeration foster incremental or radical innovation?

2022

[EN] This study answers the question on whether areas of agglomeration or high industry specialization constitute supportive prone-to-innovation environments for the generation of radical innovation. By drawing on the CIS distinction between incremental vs radical innovation, we disentangle the effect of industry specialization on the occurrence of radical innovations, a phenomenon mostly overlooked. By analysing a large dataset of 3,602 firms from CIS and other geographic datasets, results show that a firm's location in high industry specialization areas primarily trims incremental but not radical innovation. Firms' internal knowledge bases do matter more for radical innovation to occur, r…

Determinants of website traffic: the case of European fashion apparel retailers

2014

The globalization process together with the extraordinary growth in the use of Internet offer firms new growth opportunities. Retail firms are using a multichannel approach, involving the Internet, in their internationalization strategies. Website traffic as measured by unique users and online awareness is among the measures for assessing the success of the online channel. There is little evidence, however, linking website traffic and the characteristics of the retail multichannel internationalization process. In order to fill this gap, this paper analyses the factors explaining the retailer's international website traffic. Website traffic data for a sample of European fashion apparel retai…

Standard and non-standard neutrino properties

2002

I review the interpretation of solar and atmospheric neutrino data in terms neutrino oscillations and describe some ways to account for the required neutrino masses and mixing angles from first principles, both within top-down and bottom-up approaches. I also discuss non-oscillation phenomena such as nu-less double beta which may probe the absolute scale of neutrino mass, and also reveal its Majorana nature. I note that leptonic CP violation induced by ``Majorana'' phases drop from oscillations but play a role in the leptogenesis scenario for the baryon asymmetry of the Universe. Direct tests of leptonic CP violation in oscillation experiments, such as neutrino factories, will be a tough ch…

Assessing the impact of operating lease capitalization with dynamic Monte Carlo simulation

2019

Abstract The European Commission has recently adopted a new accounting standard for leases that will be implemented in 2019, which requires operating lease contracts to be included in the balance sheet, affecting key ratios, leverage and profitability. We simulate the impact of IFRS 16 using Monte Carlo method, which incorporates the uncertainty of the future value of variables when making predictions. Unlike prior studies based on historical data, our study considers a five-year forecast horizon and, more importantly, contemplates several probable scenarios. Based on the STOXX All Europe 100, our results confirm that, in 2019, liability maturity, liquidity and return on assets will decreas…

Exploring Integrated Marketing Communications, Brand Awareness, and Brand Image in Hospitality Marketing: A Cross-Cultural Approach

2016

Purpose – The purpose of this paper is to assess customer perceptions of integration of marketing communications, brand awareness, and brand image in hospitality. Moreover, cross-cultural differences are considered when evaluating all the concepts, since national culture can have a considerable impact on customer behavior. Design/Methodology/Approach – After a literature review of the examined concepts, the results of an empirical study are presented and discussed. The empirical investigation was carried out by approaching 475 guests of upscale Croatian hotels. The SPSS software was employed for data analysis. Findings and implications – The results indicate that hotel guests assessed integ…

Intentions to use mobile services: Antecedents and cross-service comparisons

2005

- This article develops and tests a model to explain consumers' intention to use mobile services. Through triangulating theories from the diverse fields of information systems research, uses and gratification research, and domestication research, the authors put forth an integrated model that explains intention to use mobile services. The model proposes four overall influences on usage intention: motivational influences, attitudinal influences, normative pressure, and perceived control. The authors study the type of interactivity and process characteristics associated with the service that moderate the effects on the relationship between the proposed antecedents and usage intention. The res…

Mobile Semantics: Defining Concepts and their Interrelationships

2006

Abstract As service offerings and technologies constantly develop there seems to be confusion over what we are actually talking about when we talk about mobile services. A requirement for constructing an organized body of knowledge in a specific area of research is the clarity of its basic concepts. Often, we are not specifically interested in defining things but to examine and discuss the subjects of our primary interest we need unambiguous and shared definitions of our key concepts. Although many relevant concepts undoubtedly have clear definitions in the minds of experienced scholars working in the field of mobile offerings, for some reason these definitions are not well articulated or e…
