Dynamic learning as entrepreneurial action in the context of open innovation:an instrumental case from a communities-of-practice perspective

Recent scholarly discussion on open innovation put forward the notion that an organisation's ability to internalise external knowledge and learn from various sources in undertaking new product development is crucial to its competitive performance. Nevertheless, little attention has been paid to how growth-oriented small firms identify and exploit entrepreneurial opportunities (i.e. take entrepreneurial action) related to such development, in an open innovation context, from a social learning perspective. This chapter, based on an instrumental case-firm, demonstrates analytically how learning as entrepreneurial action takes place, drawing on situated learning theory. It is argued that such learning is dynamic in nature and is founded on specific organising principles that foster both inter- and intracommunal learning. © 2012, IGI Global.

The influence of socio-cultural environments on the performance of nascent entrepreneurs:an instrumental variable approach

The importance of informal institutions and in particular culture for entrepreneurship is a subject of ongoing interest. Past research has mostly concentrated on cross-national comparisons, cultural values, and the direct effects of culture on entrepreneurial behavior, but in the main found inconsistent results. The present research adds a fresh perspective to this research stream by turning attention to community-level culture and cultural norms. We hypothesize indirect effects of cultural norms on venture emergence. Specifically that community-level cultural norms (performance-based culture and socially-supportive institutional norms) impact important supply-side variables (entrepreneurial self-efficacy and entrepreneurial motivation) which in turn influence nascent entrepreneurs’ success in creating operational ventures (venture emergence). We test our predictions on a unique longitudinal data set (PSED II) tracking nascent entrepreneurs venture creation efforts over a 5 year time span and find evidence supporting them. Our research contributes to a more fine-grained understanding of how culture, in particular perceptions of community cultural norms, influences venture emergence. This research highlights the embeddedness of entrepreneurial behavior and its immediate antecedent beliefs in the local, community context.

It is described tool ontology-controlled complex for research and developments of sensor systems. Some approaches to solution most frequently meeting tasks are considered for creation of the recognition procedures.

Hybrid sampling on mutual information entropy-based clustering ensembles for optimizations

In this paper, we focus on the design of bivariate EDAs for discrete optimization problems and propose a new approach named HSMIEC. While the current EDAs require much time in the statistical learning process as the relationships among the variables are too complicated, we employ the Selfish gene theory (SG) in this approach, as well as a Mutual Information and Entropy based Cluster (MIEC) model is also set to optimize the probability distribution of the virtual population. This model uses a hybrid sampling method by considering both the clustering accuracy and clustering diversity and an incremental learning and resample scheme is also set to optimize the parameters of the correlations of the variables. Compared with several benchmark problems, our experimental results demonstrate that HSMIEC often performs better than some other EDAs, such as BMDA, COMIT, MIMIC and ECGA. © 2009 Elsevier B.V.

Variables affecting the collection and preservation of human scent components through instrumental and biological evaluations

In certain European countries and the United States of America, canines have been successfully used in human scent identification. There is however, limited scientific knowledge on the composition of human scent and the detection mechanism that produces an alert from canines. This lack of information has resulted in successful legal challenges to human scent evidence in the courts of law. ^ The main objective of this research was to utilize science to validate the current practices of using human scent evidence in criminal cases. The goals of this study were to utilize Headspace Solid Phase Micro Extraction Gas Chromatography Mass Spectrometry (HS-SPME-GC/MS) to determine the optimum collection and storage conditions for human scent samples, to investigate whether the amount of DNA deposited upon contact with an object affects the alerts produced by human scent identification canines, and to create a prototype pseudo human scent which could be used for training purposes. ^ Hand odor samples which were collected on different sorbent materials and exposed to various environmental conditions showed that human scent samples should be stored without prolonged exposure to UVA/UVB light to allow minimal changes to the overall scent profile. Various methods of collecting human scent from objects were also investigated and it was determined that passive collection methods yields ten times more VOCs by mass than active collection methods. ^ Through the use of polymerase chain reaction (PCR) no correlation was found between the amount of DNA that was deposited upon contact with an object and the alerts that were produced by human scent identification canines. Preliminary studies conducted to create a prototype pseudo human scent showed that it is possible to produce fractions of a human scent sample which can be presented to the canines to determine whether specific fractions or the entire sample is needed to produce alerts by the human scent identification canines. ^

Toddlers' prosocial behavior: from instrumental to empathic to altruistic helping.

The study explored how the meaning of prosocial behavior changes over toddlerhood. Sixty-five 18- and 30-month-olds could help an adult in 3 contexts: instrumental (action based), empathic (emotion based), and altruistic (costly). Children at both ages helped readily in instrumental tasks. For 18-month-olds, empathic helping was significantly more difficult than instrumental helping and required greater communication from the adult about her needs. Altruistic helping, which involved giving up an object of the child's own, was the most difficult for children at both ages. Findings suggest that over the 2nd year of life, prosocial behavior develops from relying on action understanding and explicit communications to understanding others' emotions from subtle cues. Developmental trajectories of social-cognitive and motivational components of early helping are discussed.

Un répertoire de musique brésilienne adapté à l’enseignement collectif du trombone

Cette thèse, complémentaire à deux récitals donnés dans le cadre de la réalisation d’un doctorat en études pédagogiques et pratiques musicales instrumentales, a comme fil conducteur l’enseignement collectif du trombone au Brésil et examine le trombone sous trois angles : historique, pédagogique et dans une perspective d’interprétation musicale. Bien que le sujet ne soit pas nouveau, le projet présente une réflexion, sur le trombone et son enseignement, encore inexplorée en raison principalement du répertoire sélectionné pour la présente étude. En effet, à notre connaissance, le répertoire populaire brésilien n’a jusqu’à maintenant pas fait l’objet d’arrangements musicaux écrits, en vue d’une exploitation non seulement en contexte de représentation publique, mais aussi avec des visées pédagogiques. Les morceaux choisis ont été retenus en raison de leur contenu, qui présente un vocabulaire musical lié à la culture régionale de quatre des cinq régions géographiques du Brésil. Dans le processus de réalisation du projet, les morceaux choisis ont fait l’objet d’arrangements dans la perspective qu’ils servent comme outil pédagogique pour la formation en trombone, en contexte de musique brésilienne. Les arrangements ont été conçus pour des ensembles réduits, où le trombone tient fréquemment le rôle de soliste. Ainsi, au-delà des concepts et techniques issus de la formation traditionnelle reçue, l’interprétation des arrangements a été une occasion pour le doctorant et soliste de présenter, à travers l’improvisation dans le langage de la musique populaire brésilienne, les résultats de processus développés au cours des deux dernières années. Les partitions sont annexées au texte de la thèse, afin d’illustrer certains propos et avec l’objectif de soutenir les recherches futures dans ce domaine. La thèse est divisée en quatre chapitres lesquels, bien que présentés séparément, possèdent entre eux d’étroites relations. Le premier chapitre donne un aperçu général de l’histoire de l’instrument, à travers les cinq siècles de son existence. Le deuxième chapitre s’articule autour de l’histoire de la musique brésilienne et de la présence du trombone au Brésil. Le troisième chapitre présente d’abord un aperçu de l’enseignement artistique et musical au Brésil au 20e et 21e siècle, poursuit en abordant la situation de l’enseignement du trombone au Brésil et aboutit à une proposition favorisant l’apprentissage du trombone en contexte d’enseignement musical collectif. Finalement, le quatrième chapitre fait un retour sur l’expérience musicale vécue dans le premier volet du projet, celui se rapportant à la pratique musicale instrumentale, établit des liens et trace des pistes dans une perspective d’enseignement et d’apprentissage du trombone.

Antonio Salieri's La calamita de' cuori (1774): Sources, Form, Context

Antonio Salieri’s La calamita de’ cuori (1774) warrants musicological attention for what it can tell us about Salieri’s compositional craft and what it reveals about the development of form in Viennese Italian-language comic opera of the mid- and late-eighteenth century. In Part I of this dissertation, I explore the performance history of La calamita, present the first plot synopsis and English translation of the libretto, and describe the variants between Carlo Goldoni’s 1752 libretto and the revised version created for Salieri’s opera. I have collated Salieri’s holograph score, Österreichische Nationalbibliothek, Vienna, Mus. Hs. 16.508, with four copies having different relationships to it, and I propose a stemma that represents the relationships between these five sources. The analyses in Part II contribute to our understanding of formal practices in eighteenth-century drammi giocosi. My study of Salieri’s La calamita reveals his reliance on a clearly defined binary structure, referred to in this dissertation as “operatic binary form,” in almost half of the arias, ensembles, and instrumental movements of this opera. Salieri’s consistent use of operatic binary form led me to explore its use in drammi giocosi by other prominent composers of this time, including Baldassare Galuppi’s La calamita de’ cuori (1752), Wolfgang Amadeus Mozart’s Il dissoluto punito, ossia Il Don Giovanni (1787), and selected arias by Pasquale Anfossi, Florian Leopold Gassmann, Giuseppe Gazzaniga, Franz Joseph Haydn, Giovanni Paisiello, and Niccolò Piccinni dating from 1760 to 1774. This study showed that Salieri and his peers adhered to a recognizable tonal plan and set of design elements in their operatic binary forms, and that their arias fall into three distinct categories defined by the tonality at the beginning of the second half of the binary structure. The analysis presented here adds to our present understanding of operatic form in mid- and late-century drammi giocosi and shows that in La calamita de’ cuori, Salieri was following the normative formal procedures of his time.
