Complementarity between technology make and buy in innovation strategies: Evidence from Belgiam manufacturing firms

This paper characterizes the innovation strategy of manufacturing firms andexamines the relation between the innovation strategy and importantindustry-, firm- and innovation-specific characteristics using Belgiandata from the Eurostat Community Innovation Survey. In addition to importantsize effects explaining innovation, we find that high perceived risks andcosts and low appropriability of innovations do not discourage innovation,but rather determine how the innovation sourcing strategy is chosen. Withrespect to the determinants of the decision of the innovative firm toproduce technology itself (Make) or to source technology externally (Buy),we find that small firms are more likely restrict their innovation strategyto an exclusive make or buy strategy, while large firms are more likely tocombine both internal and external knowledge acquisition in their innovationstrategy. An interesting result that highlights the complementary nature ofthe Make and Buy decisions, is that, controlled for firm size, companies forwhich internal information is an important source for innovation are morelikely to combine internal and external sources of technology. We find thisto be evidence of the fact that in-house R&D generates the necessaryabsorptive capacity to profit from external knowledge acquisition. Also theeffectiveness of different mechanisms to appropriate the benefits ofinnovations and the internal organizational resistance against change areimportant determinants of the firm's technology sourcing strategy.

Trends in hours, balanced growth and the role of technology in the business cycle

The present paper revisits a property embedded in most dynamic macroeconomic models: the stationarity of hours worked. First, I argue that, contrary to what is often believed, there are many reasons why hours could be nonstationary in those models, while preserving the property of balanced growth. Second, I show that the postwar evidence for most industrialized economies is clearly at odds with the assumption of stationary hours per capita. Third, I examine the implications of that evidence for the role of technology as a source of economic fluctuations in the G7 countries.

External technology sources: Embodied or disembodied technology acquisition

This paper analyzes the choice between different innovationactivities of a firm. In particular, we study the technologyacquisition decision of the firm, i.e. its technology BUYdecision as part of the firm's innovation strategy. We take a closer look at the different types of external technologyacquisition where we distinguish two broad types of technologybuy decisions. On the one hand, the firm can acquire new technology which is embodied in an asset that is acquired suchas new personnel or (parts of) other firms or equipment. On the other hand, the firm can obtain new technology disembodiedthrough a licensing agreement or by outsourcing the technologydevelopment from an R&D contractor or consulting agency. Through a series of Probit regressions, we discuss variables that might affect external technology acquisition choices of the firm andpay special attention to the firm's abilities to scan the market for technology and to absorb the technology acquired. Furthermore, we analyze the effect of different appropriationregimes on the decision of the firm to source technology.

Metabolic labeling and protein linearization technology allow the study of proteins secreted by cultured cells in serum-containing media.

Supernatants from cell cultures (also called conditioned media, CMs) are commonly analyzed to study the pool of secreted proteins (secretome). To reduce the exogenous protein background, serum-free media are often used to obtain CMs. Serum deprivation, however, can severely affect cell viability and phenotype, including protein secretion. We present a strategy to analyze the proteins secreted by cells in fetal bovine serum-containing CMs, which combines the advantage of metabolic labeling and protein concentration linearization techniques. Incubation of CMs with a hexapeptide ligand library was used to reduce the dynamic range of the samples and led to the identification of 3 times more proteins than in untreated CM samples. Labeling with a deuterated amino acid was used to distinguish between cellular proteins and homologous bovine proteins contained in the medium. Application of the strategy to two breast cancer cell lines led to the identification of proteins secreted in different amounts and which could correlate with their varying degree of aggressiveness. Selected reaction monitoring (SRM)-based quantitation of three proteins of interest in the crude samples yielded data in good agreement with the results from concentration-equalized samples.

Characterization of intonation in Karṇāṭaka music by parametrizing context-based Svara Distributions

Intonation is a fundamental music concept that has a special relevance in Indian art music. It is characteristic of the rāga and intrinsic to the musical expression of the performer. Describing intonation is of importance to several information retrieval tasks like the development of rāga and artist similarity measures. In our previous work, we proposed a compact representation of intonation based on the parametrization of the pitch histogram of a performance and demonstrated the usefulness of this representation through an explorative rāga recognition task in which we classified 42 vocal performances belonging to 3 rāgas using parameters of a single svara. In this paper, we extend this representation to employ context-based svara distributions, which are obtained with a different approach to find the pitches belonging to each svara. We quantitatively compare this method to our previous one, discuss the advantages, and the necessary melodic analysis to be carried out in future.

An approach for linking score and audio recordings in Makam music of Turkey

The main information sources to study a particular piece of music are symbolic scores and audio recordings. These are complementary representations of the piece and it isvery useful to have a proper linking between the two of the musically meaningful events. For the case of makam music of Turkey, linking the available scores with the correspondingaudio recordings requires taking the specificities of this music into account, such as the particular tunings, the extensive usage of non-notated expressive elements, and the way in which the performer repeats fragmentsof the score. Moreover, for most of the pieces of the classical repertoire, there is no score written by the original composer. In this paper, we propose a methodology to pair sections of a score to the corresponding fragments of audio recording performances. The pitch information obtained from both sources is used as the common representationto be paired. From an audio recording, fundamental frequency estimation and tuning analysis is done to compute a pitch contour. From the corresponding score, symbolic note names and durations are converted to a syntheticpitch contour. Then, a linking operation is performed between these pitch contours in order to find the best correspondences.The method is tested on a dataset of 11 compositions spanning 44 audio recordings, which are mostly monophonic. An F3-score of 82% and 89% are obtained with automatic and semi-automatic karar detection respectively,showing that the methodology may give us a needed tool for further computational tasks such as form analysis, audio-score alignment and makam recognition.

Menestystarinoilla maailmalle : Music Export Finland musiikkialan yrittäjien tukena kansainvälistymisessä

Opinnäytetyö on kirjallinen selvitys, jossa kartoitetaan musiikkialan ammattilaisten näkemyksiä musiikkialan vientiorganisaatio Music Export Finlandin vienninedistämistyön palveluista. Työn tarkoituksena on selvittää, minkälaiseksi vientityötä jo jonkin aikaa tehneet yrittäjät kokevat ja määrittelevät yhdistyksen roolin sekä sen palveluiden tarpeellisuuden omassa käytännön vientityössään. Teoreettinen viitekehys muodostettiin vientitoiminnan käsikirjoista sekä asiantuntijaorganisaatio Finpron kansainvälistymisstrategian mallista, jonka pohjalta tehtiin myös kuuden asiantuntijan haastattelut. Musex tarjoaa palveluita lähinnä vientitoiminnan käytännön toteutusvaiheeseen. Musexin olemassaolo koetaan alalla yleisesti positiiviseksi asiaksi, vaikka vientityötä jo jonkin aikaa tehneet yrittäjät eivät välttämättä hyödykään yhdistyksen palveluista käytännön tasolla. Musex näyttäytyy heille lähinnä alan yleisen tiedottajan roolissa, musiikkialan yhteisenä äänitorvena, jonka tehtävä on ylläpitää toimivia suhteita valtiovaltaan, lisätä toimialan näkyvyyttä ja edesauttaa toimialan rakenteiden kehittämistä alan intressien mukaisesti. Heille on tärkeää, että musiikkitoimialan tunnettuus ja arvostus lisääntyvät julkisen vallan edustajien joukossa, mitä kautta tarvittavaa rakennemuutosta voidaan viedä konkreettisesti eteenpäin. Musiikkialalla menestyy se, joka hallitsee koko laajan liiketoiminnallisen paketin sekä pystyy tarjoamaan faneilleen jotain ainutlaatuista ja eksklusiivista. Musiikkialan yrityksissä harjoitetaan ammattimaista vientitoimintaa alalle ominaisilla tavoilla ja strategioilla, jotka useinkin poikkeavat monen muun alan menettelytavoista. Vientityön tekeminen edellyttää yrityksiltä halua ja kykyä ajatella liiketoiminnallisesti koko toimintaa, sekä paljon työtä. Yhteistyö koko alan kesken on kansainväliselle toiminnalle ehdotonta. Musiikkitoimialan suurin kompastuskivi yhä edelleen on yleisen arvostuksen ja uskottavuuden puute tai sen vähäisyys, sekä rahoitus. Opinnäytetyö on hankkeistettu sekä Musexin kanssa että Stadian t&k -hankkeeseen Suomalaisten musiikkialan pienyrittäjien vientivalmiuksien kehittäminen.

From radiobiology to technology: what is changing in radiotherapy for prostate cancer.

In the last decades, new technologies have been introduced in the daily clinical practice of the radiation oncologist: 3D-Conformal radiotherapy (RT) became almost universally available, thereafter, intensity modulated RT (IMRT) gained large diffusion, due to its potential impact in improving the clinical outcomes, and more recently, helical and volumetric arc IMRT with image-guided RT are becoming more and more diffused and used for prostate cancer patients. The conventional dose-fractionation results to be the best compromise between the efficacy and the safety of the treatment, but combining new techniques, modern RT allows to overcame one of the major limits of the 'older' RT: the impossibility of delivering higher total doses and/or high dose/fraction. The evidences regarding radiobiology, clinical and technological evolution of RT in prostate cancer have been reported and discussed.
