Why not all young firms invest in R&D

This article aims to analyze the different impact that some factors may exert on the probability that a small young firm invests intensively in R&D. Recently, an increasing amount of the literature makes reference to the vital role played by a small number of young firms in generating jobs and increasing efficiency levels. However, not all new firms invest in R&D. Departing from the definition of YICs (firms younger than 6 years old, fewer than 250 employees and with more than 15% of their revenues invested in R&D activities), and with an extensive sample of the Spanish Community Innovation Survey between 2004- 2010, we try to determine: i) those factors that cause firms to become YICs (innovative young small firms) or YNICs (moderately innovative young small firms); ii) what is the difference in the impact of those factors between YICs and YNICs. Our results show that factors such as initial innovation capacity and cooperation in R&D projects enhance the probability of becoming a YIC. Nevertheless, factors such as export potential and market uncertainty may influence the decision to invest moderately and become a YNIC. Keywords: Innovation, Policy, YICs.

New EBG solutions for mutual coupling reduction

Electromagnetic Band Gap (EBG) based on Frequency Selective Surfaces (FSS) [1] are one type of metamaterials [2] with electrical properties [3]. This EBG are used in mutual coupling reduction, back lobe radiation reduction, etc. In this work not only new shapes for the mushroom-type are presented, but also multilayered configurations were studied in order to reduce the patch size and the necessary number of elements.

Evaluating new interaction paradigms in SEN teaching: defining the experiment

New devices have made their way into everyday life in recent years, opening the doors to new ways of interacting with computers, providing different, and potentially better, solutions to some problems. But this raises the question of if there is any way of measuring whether or not these new devices are suitable. This paper presents a strategy for evaluating the suitability of new interaction devices in the context of teaching children with special educational needs

Review of "Comorbidity, disability and the need for treatment for DSM-IV psychiatric disorders in an insured population"

Background: This study presents estimates of 12 month and current prevalences of DSM-IV disorders, and the related comor-bidity, disability and service utilization, derived from a national probability sample in Australia. Methods: The DSM-IV psychiatric disorders among persons aged 18 and over in the Australian population were assessed with data collected by lay interviewers using the Composite International Diagnostic Interview, other screening interviews and measures of disability and service utilization. The response rate was 78.1% and the final sample size was 10,641 adults. Results: Close to 20% reported at least one twelve month disorder and 13% a disorder current within the past 30 days. ICD-10 diagnoses were also derived, DSM-IV was the more conservative classification whether or not the new clinical significance criteria was applied. Major depression, any personality disorder, and alcohol dependence were the three most common twelve month disorders, generalized anxiety disorder replaced alcohol dependence as the third most common current disorder. The sexes has similar rates of any disorder, but women had higher rates of affective and anxiety disorders, men higher rates of substance use disorders. Prevalence of most disorders declined with age and education, and were lower among those employed or married. Respondents whose symptoms met criteria for three or more disorders in the past year had greatly increased rates of disability and of mental health consultations. The affective and somatoform disorders were associated with the highest rates of disability. Only 36% of people with a mental disorder this year had consulted for a mental problem, and most had seen a general practitioner. We identified those with a current disorder who were disabled or multiply comorbid - only half had consulted and of those who had not, more than half said they did not need treatment. Conclusions: The 12 month prevalence was lower than reported in the US National Comorbidity Survey but method factors might account for this. The relationships between prevalence and demographic variables, and between comorbidity, disability and service utilization were similar to those found in the US survey. Australia has a national health insurance scheme with total coverage and access to medical help is available to all, commonly at little or no cost. We identify the high rate of not consulting among those with a current disorder, and additional disability or multiple comorbidity, as an important public health problem. Kessler argued for more research on barriers to professional help seeking. This report reinforces his conclusion and shows that economic barriers are not the dominant issue.

Modern scientific methods and their potential in wastewater science and technology

Application of novel analytical and investigative methods such as fluorescence in situ hybridization, confocal laser scanning microscopy (CLSM), microelectrodes and advanced numerical simulation has led to new insights into micro-and macroscopic processes in bioreactors. However, the question is still open whether or not these new findings and the subsequent gain of knowledge are of significant practical relevance and if so, where and how. To find suitable answers it is necessary for engineers to know what can be expected by applying these modern analytical tools. Similarly, scientists could benefit significantly from an intensive dialogue with engineers in order to find out about practical problems and conditions existing in wastewater treatment systems. In this paper, an attempt is made to help bridge the gap between science and engineering in biological wastewater treatment. We provide an overview of recently developed methods in microbiology and in mathematical modeling and numerical simulation. A questionnaire is presented which may help generate a platform from which further technical and scientific developments can be accomplished. Both the paper and the questionnaire are aimed at encouraging scientists and engineers to enter into an intensive, mutually beneficial dialogue. (C) 2002 Elsevier Science Ltd. All rights reserved.

Characterizing the timing behaviour of power-line communication by means of simulation

Although power-line communication (PLC) is not a new technology, its use to support communication with timing requirements is still the focus of ongoing research. Recently, a new infrastructure was presented, intended for communication using power lines from a central location to geographically dispersed nodes using inexpensive devices. This new infrastructure uses a two-level hierarchical power-line system, together with an IP-based network. Within this infrastructure, in order to provide end-toend communication through the two levels of the powerline system, it is necessary to fully understand the behaviour of the underlying network layers. The masterslave behaviour of the PLC MAC, together with the inherent dynamic topology of power-line networks are important issues that must be fully characterised. Therefore, in this paper we present a simulation model which is being used to study and characterise the behaviour of power-line communication.

Queuing and routing in a hierarchical powerline communication system

Although power-line communication (PLC) is not a new technology, its use to support data communication with timing requirements is still the focus of ongoing research. A new infrastructure intended for communication using power lines from a central location to dispersed nodes using inexpensive devices was presented recently. This new infrastructure uses a two-level hierarchical power-line system, together with an IP-based network. Due to the master-slave behaviour of the PLC medium access, together with the inherent dynamic topology of power-line networks, a mechanism to provide end-to-end communication through the two levels of the power-line system must be provided. In this paper we introduce the architecture of the PLC protocol layer that is being implemented for this end.

Transnational identities in the fiction of Monica Ali: In the Kitchen and Alentejo Blue

Monica Ali’s In the Kitchen shows London as a cosmopolitan and postmodern city, a locus of transnational identities. Although this is not a new theme in contemporary English writing, in this novel the topic of migration is detached from the usual postcolonial loci that feature in “immigrant” or “diasporic” literature. In the novel Alentejo Blue, set in the South of Portugal, Monica Ali had already approached the question of migration from the point of view of the exiled citizen, whose situation is part of globalization processes outside of the normal push/pull (centre/periphery, east/west, north/south) conceptions of migration. The focus in the article is, thus, on the ways the new world order of economic globalization relates to the processes of immigration and the dispersal of a stable sense of individual and national identity.

Dermatite verrucosa leprotica (Estudo de 3 casos)

The writer has discovered in Curupaity (National Leprosarium, Rio de Janeiro), three cases of verrucous dermatitis in C 3 type lepers. He suspected it to be an association of leprosy with Dermatilis verrucosa blastomycetica (Chromoblastocycosis) but various attempts to cultivate the fungus (Acrotheca or Hormodendrum Pedrosoi) responsible for the disease gave negative results and also the histopathologic aspect of the verrucous tissue proved it to be a leprotic granuloma without mycotic association. The writer's conclusion, based upon the cultural and histopathological studies, is that the verrucous dermatitis observed is due to leprosy alone, considering it as a new syndrome of the disease and not a new clinical form. He has called it « Dermatitis verrucosa leprotica » and made suggestions to all doctors of leprosaria to look for new cases and to study their etiology and pathogeny. Electrocoagulation improved the lesions.

Ramaderia extensiva com a eina de prevenció d'incendis i gestió del paisatge a Matadepera (Vallès Occidental)

Aquest es un estudi de la contribució d’un ramat mixt d’oví i cabrum a la gestió de les masses forestals per a la prevenció d’incendis al municipi de Matadepera. L’avaluació de l’acció del ramat s’ha efectuat mitjançant un estudi integrat a traves del coneixement local i l’estudi ecològic de les zones pasturades. La ramaderia extensiva i especialment els ramats d’ovelles i cabres han contribuït durant segles a la neteja del sotabosc mitjançant l’aprofitament productiu d’aquestes zones, per tant no es quelcom nou, sinó un reconeixement als serveis ecològics no productius de la ramaderia extensiva i com aquesta es eficaç en la prevenció d’incendis forestals.
