A multi-dimensional analysis on how different types of innovations impact SMEs business performance

This paper examines the impact of innovation decisions on business performance for small and medium-sized enterprises based on a multi-dimensional analytical approach. With this aim, the impact of the firm’s innovation decisions (in terms of the introduction of product, process, and/or organisational innovation) on four alternative performance indicators (two financial indicators: sales increase and cost reduction; and two operational indicators: increase of productive capacity and improvement in quality) is analysed. Additionally, an array of potential moderating determinants (such as firm and entrepreneur characteristics) are controlled for. Our findings highlight the existence of positive impacts of innovation decisions on both dimensions of business performance (financial and operational), but these impacts significantly differ depending on the type of innovation and the performance indicator considered. Thus, in order to study the multifaceted effects of innovation decisions made by the firm, results point out that the relationship between innovation (product, process, or organisational) and business performance should be analysed from a multi-dimensional approach. These findings imply significant implications for the design and implementation of innovation strategies in SMEs, since these should be tailored according to the business performance sought by the firm

The effects of innovation on the decisions of exporting and/or importing in SMEs: empirical evidence in the case of Spain

This paper analyses the involvement of small firms in international trade activities by identifying the comprehensive impact of innovation. Specifically, we study how innovation introduced by these firms determines entrepreneurial decision-making process regarding whether to engage in exporting and/or importing. Moreover, we account for several innovation outputs (product, process, and organisational/managerial innovation) when estimating the potentially interrelated decisions of whether to export and/or import. Results confirm the simultaneity of firms’ exporting and importing decisions and consequently these two decisions should be estimated together when analysing the influence incurred by the introduction of alternative types of innovation on said decisions. Furthermore, findings show complementarity between types of innovation to be relevant in explaining export and import decisions made by SMEs. Specifically, cumulative effects as a result of combining product and process innovation, as well as of product, process and organisational innovation, are highly significant in explaining export decisions, while in the case of imports, the combination of product and organisational innovation is shown to be significant. These findings lead to major policy and managerial implications regarding the promotion of SMEs’ participation in international trade flows through alternative innovation strategies

Analyzing and testing viewability methods in an advertising network

Many of the current online businesses base completely their revenue models in earnings from online advertisement. A problematic fact is that according to recent studies more than half of display ads are not being detected as viewable. The International Advertising Bureau (IAB) has defined a viewable impression as an impression that at least 50% of its pixels are rendered in the viewport during at least one continuous second. Although there is agreement on this definition for measuring viewable impressions in the industry, there is no systematic methodologies on how it should be implemented or the trustworthiness of these methods. In fact, the Media Rating Council (MRC) announced that there are inconsistencies across multiple reports attempting to measure this metric. In order to understand the magnitude of the problem, we conduct an analysis of different methods to track viewable impressions. Then, we test a subset of geometric and strong interaction methods in a webpage registered in the worldwide ad-network ExoClick, which currently serves over 7 billion geo-targeted ads a day to a global network of 65000 web/mobile publisher platforms. We find that the Intersection Observer API is the method that detects more viewable impressions given its robustness towards the technological constraints that face the rest of implementations available. The motivation of this work is to better understand the limitations and advantages of such methods, which can have an impact at a standardisation level in online advertising industry, as well as to provide guidelines for future research based on the lessons learned.This work was possible thanks to the support of “Plan de Doctorados Industriales de la Secretaría de Universidades e Investigación del Departamento de Empresa y Conocimiento de la Generalitat de Catalunya” and the Spanish Ministry of Economy and Competitiveness through the Juan de la Cierva Formación program (FJCI-2017-34926).

Selection of internal control genes for quantitative real-time RT-PCR studies during tomato development process

<p>Abstract</p> <p>Background</p> <p>The elucidation of gene expression patterns leads to a better understanding of biological processes. Real-time quantitative RT-PCR has become the standard method for in-depth studies of gene expression. A biologically meaningful reporting of target mRNA quantities requires accurate and reliable normalization in order to identify real gene-specific variation. The purpose of normalization is to control several variables such as different amounts and quality of starting material, variable enzymatic efficiencies of retrotranscription from RNA to cDNA, or differences between tissues or cells in overall transcriptional activity. The validity of a housekeeping gene as endogenous control relies on the stability of its expression level across the sample panel being analysed. In the present report we describe the first systematic evaluation of potential internal controls during tomato development process to identify which are the most reliable for transcript quantification by real-time RT-PCR.</p> <p>Results</p> <p>In this study, we assess the expression stability of 7 traditional and 4 novel housekeeping genes in a set of 27 samples representing different tissues and organs of tomato plants at different developmental stages. First, we designed, tested and optimized amplification primers for real-time RT-PCR. Then, expression data from each candidate gene were evaluated with three complementary approaches based on different statistical procedures. Our analysis suggests that SGN-U314153 (<it>CAC</it>), SGN-U321250 (<it>TIP41</it>), SGN-U346908 ("<it>Expressed</it>") and SGN-U316474 (<it>SAND</it>) genes provide superior transcript normalization in tomato development studies. We recommend different combinations of these exceptionally stable housekeeping genes for suited normalization of different developmental series, including the complete tomato development process.</p> <p>Conclusion</p> <p>This work constitutes the first effort for the selection of optimal endogenous controls for quantitative real-time RT-PCR studies of gene expression during tomato development process. From our study a tool-kit of control genes emerges that outperform the traditional genes in terms of expression stability.</p

Use-wear and residue analysis of pounding tools used by wild capuchin monkeys (Sapajus libidinosus) from Serra da Capivara (Piauí, Brazil)

Bearded capuchin monkeys (Sapajus libidinosus) from Serra da Capivara National Park (Brazil), perform the widest range of activities using stone tools of all the non-human tool-using primates. The behaviours behind this range of tool-use have been closely documented, but little is known about the characteristics of the tools themselves. Here we redress this imbalance and adopt an archaeological perspective to the analysis of capuchin pounding tools. We apply, for the first time, systematic microscopic techniques to the analysis of capuchin stone tools used for digging, cracking cashew nuts and seed processing to characterise their damage patterns combined with residue spatial distribution and micro-remains analysis. This work presents a standardized methodology for future primate archaeological use-wear studies as well as forming a reference collection which can be used to identify different activities within the primate archaeological record. Furthermore, understanding the archaeologically visible traces of primate percussive behaviours represents an initial step in developing a methodology to investigate if similar activities were practiced by early hominins and to help identify these activities in the Plio-Pleistocene archaeological record

Sartre and the Aristotelian power and freedom

El objeto de este artículo es precisar el posicionamiento de Sartre ante la potencia y la libertad aristotélicas a la hora de dar cuenta de la efabilidad general del ser. Sartre toma como punto de partida la tesis de la opacidad del ser-en-sí, la cual determina que todo lo decisivo en lo que se refiere a posibilidad, sentido, fines quede del lado de la conciencia, la libertad, la responsabilidad y la acción del hombre.The aim of this article is to clarify the position of Sartre dissenting of Aristotelian power and freedom when it comes to accounting for the general effiability of being. For this, Sartre takes as its starting point the thesis of the opacity of being-in-itself, which determines that everything decisive meaning as possibility, sense, purposes are on the side of consciousness, freedom, responsibility and the action of man

Changes in dip and frictional properties of the basal detachment controlling orogenic wedge propagation and frontal collapse: the External central Betics case

Thin-skinned fold-and-thrust belts (FTBs) have been extensively studied through both field examples and modelling. The overall dynamics of FTBs are, therefore, well understood. One less understood aspect is the combined influence of across-strike changes in the detachment properties and the basement topography on the behaviour of an orogenic wedge. In this paper, we use field data together with reflection seismic interpretation from the External Zones of the Central Betics FTB, S Spain, to identify a significant increase in the wedge basal dip (a basement "threshold") coinciding with the pinch-out of a weak substrate. This induced both changes to the wedge geometry and to the basal friction, which in turn influenced the wedge dynamics. The changing dynamics led to a transient “stagnation” of the FTB propagation, topographic build-up and subsequent collapse of the FTB front. This in turn fed an important Langhian depocenter made up of mass transport deposits. Coevally with the FTB propagation, extension took place both parallel and perpendicular to the orogenic trend. This case study illustrates how across-strike changes in wedge basal properties can control the detailed behaviour of a developing FTB front, but questions remain regarding the time-space interaction and relative importance of the basal parameters
