The organizational structure of online academic advising

Academic advising is a key element for learning success in virtual environments that has received little attention from researchers. This paper focuses on the organizational arrangements needed for the delivery of academic advising in online higher education. We present the general dimensions of organizational structures (division of labor, hierarchy of authority and formalization) and their possible forms when applied to academic advising. The specific solution adopted at the Open University of Catalonia is described and assessed in order to draw general conclusions of interest for other institutions.

Mucoviscidose: illustration de la complexité du dépistage génétique. [The example of cystic fibrosis to highlight the complexity of genetic screening].

Différentes organisations et différents pays aboutissent souvent à des conclusions différentes quant à la pertinence d'introduire un test de dépistage génétique dans la population générale. Cet article décrit la complexité du dépistage basé sur des tests génétiques. Utilisant l'exemple de la mucoviscidose - pour laquelle un groupe de travail national est en train d'évaluer la pertinence d'un dépistage génétique - les auteurs relèvent les situaions où les recommandations de dépistage sont parfois basées sur l'émergence de nouvelles technologies (par exemple, test génétique) et d'opinion publique plutôt que sur la base d'évidences. Ils présentent également les enjeux éthiques et économiques du dépistage génétique de la mucoviscidose. [Abstract] Various institutions and countries often reach different conclusions about the utility of introducing a newborn screening test in the general population. This paper highlights the complexity of population screening including genetic tests. Using the example of cystic fibrosis genetic screening, for which a Swiss Working Group for Cystic Fibrosis is currently evaluating the pertinence, we outline that screening recommendations are often based more on expert opinion and emerging new technologies rather than on evidence. We also present some ethical and economic issues related to cystic fibrosis genetic screening.

A programming environment having three levels of complexity for mobile robotics = Entorno de programación con tres niveles de complejidad para robótica móvil

This paper presents a programming environment for supporting learning in STEM, particularly mobile robotic learning. It was designed to maintain progressive learning for people with and without previous knowledge of programming and/or robotics. The environment was multi platform and built with open source tools. Perception, mobility, communication, navigation and collaborative behaviour functionalities can be programmed for different mobile robots. A learner is able to programme robots using different programming languages and editor interfaces: graphic programming interface (basic level), XML-based meta language (intermediate level) or ANSI C language (advanced level). The environment supports programme translation transparently into different languages for learners or explicitly on learners’ demand. Learners can access proposed challenges and learning interfaces by examples. The environment was designed to allow characteristics such as extensibility, adaptive interfaces, persistence and low software/hardware coupling. Functionality tests were performed to prove programming environment specifications. UV BOT mobile robots were used in these tests

Pienten tuotekehityshankkeiden erityispiirteet konepajateollisuuden yrityksessä

Tutkimuksessa on tarkasteltu pienten tuotekehityshankkeiden tehokkuutta suuressa paperikoneita valmistavassa yrityksessä. Tutkimuksen osana on selvitetty sisäisen lanseerauksen kehitystarpeita oman myyntihenkilöstön aktivoinnissa, joka onolennainen osa uuden tuotteen onnistunutta markkinalanseerausta. Tuotekehityksen ja projektin johtamisen teoreettisen tutkimuksen esittelyn jälkeen tutkimuksessa on selvitetty liiketoimintaympäristön asettamia vaatimuksia yrityksen pienille tuotekehityshankkeille. Luodun teoreettisen viitekehikon avulla on tarkasteltu neljää tuotekehitysprojektia ja niiden onnistumiseen vaikuttaneita fundamentteja. Paras kilpailukyky case-liiketoiminnassa saavutetaan korkean teknologian tuotteilla, joiden kehittäminen yrityksen sisällä on strategisesti perusteltua. Matalan teknologian tuotteet tulisi hankkia pienemmiltä kilpailijoilta. Pienten kehitysprojektien nopeampi läpivienti tuoteyksiköissä vaatii yhtenäistä osaamista vaativien tuoteryhmien muodostamista sekä nykyistä selkeämpiä rooleja tuotteiden ja tuotekehityshenkilöstön välille. Organisaatiomuutoksesta johtuen tuoteyksiköiden tulee kehittää kontaktit Service-liiketoimintalinjan alaiseen myyntiverkostoon myynnin tukemiseksi. Sisäisen lanseerauksen laajuus tulee heijastaa uuden tuotteen monimutkaisuutta. Lisäksi tuotetietomyyntiverkostossa ei ole halutulla tasolla ja vaatii kehitystoimenpiteitä jatkossa.

Modeling and measuring organizational renewal capability

Globalization and new information technologies mean that organizations have to face world-wide competition in rapidly transforming, unpredictable environments, and thus the ability to constantly generate novel and improved products, services and processes has become quintessential for organizational success. Performance in turbulent environments is, above all, influenced by the organization's capability for renewal. Renewal capability consists of the ability of the organization to replicate, adapt, develop and change its assets, capabilities and strategies. An organization with a high renewal capability can sustain its current success factors while at the same time building new strengths for the future. This capability does not only mean that the organization is able to respond to today's challenges and to keep up with the changes in its environment, but also that it can actas a forerunner by creating innovations, both at the tactical and strategic levels of operation and thereby change the rules of the market. However, even though it is widely agreed that the dynamic capability for continuous learning, development and renewal is a major source of competitive advantage, there is no widely shared view on how organizational renewal capability should be defined, and the field is characterized by a plethora of concepts and definitions. Furthermore,there is a lack of methods for systematically assessing organizational renewal capability. The dissertation aims to bridge these gaps in the existing research by constructing an integrative theoretical framework for organizational renewal capability and by presenting a method for modeling and measuring this capability. The viability of the measurement tool is demonstrated in several contexts, andthe framework is also applied to assess renewal in inter-organizational networks. In this dissertation, organizational renewal capability is examined by drawing on three complimentary theoretical perspectives: knowledge management, strategic management and intellectual capital. The knowledge management perspective considers knowledge as inherently social and activity-based, and focuses on the organizational processes associated with its application and development. Within this framework, organizational renewal capability is understood as the capacity for flexible knowledge integration and creation. The strategic management perspective, on the other hand, approaches knowledge in organizations from the standpoint of its implications for the creation of competitive advantage. In this approach, organizational renewal is framed as the dynamic capability of firms. The intellectual capital perspective is focused on exploring how intangible assets can be measured, reported and communicated. From this vantage point, renewal capability is comprehended as the dynamic dimension of intellectual capital, which consists of the capability to maintain, modify and create knowledge assets. Each of the perspectives significantly contributes to the understanding of organizationalrenewal capability, and the integrative approach presented in this dissertationcontributes to the individual perspectives as well as to the understanding of organizational renewal capability as a whole.

Task complexity, the Cognition Hypothesis and second language learning and performance

In this paper we describe a taxonomy of task demands which distinguishes between Task Complexity, Task Condition and Task Difficulty. We then describe three theoretical claims and predictions of the Cognition Hypothesis (Robinson 2001, 2003b, 2005a) concerning the effects of task complexity on: (a) language production; (b) interaction and uptake of information available in the input to tasks; and (c) individual differences-task interactions. Finally we summarize the findings of the empirical studies in this special issue which all address one or more of these predictions and point to some directions for continuing, future research into the effects of task complexity on learning and performance.

Measuring organizational capabilities in the engineering and consulting industry

Tämän työn tarkoituksena oli tutkia kuinka organisaation kyvykkyyksiä voidaan mitata engineering- ja konsultointialalla käyttämällä ns. kyvykkyysauditointimenetelmää. Päämotiivit aineettoman omaisuuden mittaamiseksi tunnistettiin kirjallisuuskatsauksen pohjalta. Erilaisten menetelmien etuja ja haittoja tutkittiin, jotta kyvykkyysauditoinnin suorittamiseen liittyvät haasteet ja vaatimukset tulisivat tunnistetuiksi. Kyvykkyysauditoinnin rakentaminen vaati teollisuudenalan erityispiirteiden tunnistamista. Niiksi havaittiin tietointensiivisyys ja projektikeskeisyys. Auditoinnin implementaatioprosessi koostui neljästä osasta, joista kolmen ensimmäisen suorittamiseen case-yritys antoi merkittävän panoksensa. Kriittisten menestystekijöiden selvittämisen jälkeen voitiin niihin vaikuttavat organisaation kyvykkyydet tunnistaa ja arviointi suorittaa. Arvioinnit kerättiin sisäisiltä ja ulkoisilta arvioijilta, ja ne muodostivat pohjan analyysille, joka selvitti yrityksen kehittämistarpeita. Kyvykkyysauditoinnin hyödyiksi laskettiin kasvanut tietämys yrityksen vahvuuksista ja heikkouksista sekä mahdollisuus tarkkailla säännöllisesti sen kokonaissuorituskykyä ja parantaa sitä.

Organizational change - the personnel perpective Case: Nordea - Financial Institutions

Tutkimuksen tavoite Tutkimuksen tavoite oli kerätä FI:n johdolle tietoa henkilöstön suhtautumisesta organisaatiomuutokseen. Tutkimus toimii pohjana muutosprosessin kriittiselle tarkastelulle ja mahdollisille muutoksille resurssien kohdentamisessa. Tutkimusmenetelmä Organisaatiomuutosta käsittelevä kirjallisuus muodosti tutkielman teoriapohjan. Tutkimuksen aineisto kerättiin kyselylomakkeella FI:n henkilöstölle ja neljällä haastattelulla henkilöstön ja johdon kanssa. Johtopäätökset Yleisesti tuloksista on nähtävissä, että vastaajat ovat aluksi vastustaneet muutosta, vaikka muutos itsessään onkin nähty positiivisena kehityksenä. Vastarintaa ovat aiheuttaneet pääasiallisesti muutoksen johtamisen tyyli ja tiedotuksen kokeminen riittämättömänä.

A survey of transposable element classification systems--a call for a fundamental update to meet the challenge of their diversity and complexity.

The increase of publicly available sequencing data has allowed for rapid progress in our understanding of genome composition. As new information becomes available we should constantly be updating and reanalyzing existing and newly acquired data. In this report we focus on transposable elements (TEs) which make up a significant portion of nearly all sequenced genomes. Our ability to accurately identify and classify these sequences is critical to understanding their impact on host genomes. At the same time, as we demonstrate in this report, problems with existing classification schemes have led to significant misunderstandings of the evolution of both TE sequences and their host genomes. In a pioneering publication Finnegan (1989) proposed classifying all TE sequences into two classes based on transposition mechanisms and structural features: the retrotransposons (class I) and the DNA transposons (class II). We have retraced how ideas regarding TE classification and annotation in both prokaryotic and eukaryotic scientific communities have changed over time. This has led us to observe that: (1) a number of TEs have convergent structural features and/or transposition mechanisms that have led to misleading conclusions regarding their classification, (2) the evolution of TEs is similar to that of viruses by having several unrelated origins, (3) there might be at least 8 classes and 12 orders of TEs including 10 novel orders. In an effort to address these classification issues we propose: (1) the outline of a universal TE classification, (2) a set of methods and classification rules that could be used by all scientific communities involved in the study of TEs, and (3) a 5-year schedule for the establishment of an International Committee for Taxonomy of Transposable Elements (ICTTE).

Attitudes Toward Organizational Change among Public Middle Managers

Positive attitudes toward change (PATC) are an important current issue in public organizations facing profound financial and managerial reforms. This study aims to identify social and organizational antecedents of PATC. The investigated population is composed of middle managers working in Swiss public hospitals (N = 720), which are currently being confronted by major reforms. Partial mediation effects of organizational commitment (OC) in the relationships between independent variables and PATC are also controlled. The findings show that perceived social support (work relationships with colleagues and supervisors) as well as perceived organizational support (employee voice and participation, information and communication, work-life balance) are positively and significantly related to PATC. Stress perception is shown to have a negative impact on PATC. This article provides valuable contributions with respect to antecedents of attitudes toward change in a population of public middle managers.

Impact of model complexity on cross-temporal transferability in Maxent species distribution models: An assessment using paleobotanical data

Maximum entropy modeling (Maxent) is a widely used algorithm for predicting species distributions across space and time. Properly assessing the uncertainty in such predictions is non-trivial and requires validation with independent datasets. Notably, model complexity (number of model parameters) remains a major concern in relation to overfitting and, hence, transferability of Maxent models. An emerging approach is to validate the cross-temporal transferability of model predictions using paleoecological data. In this study, we assess the effect of model complexity on the performance of Maxent projections across time using two European plant species (Alnus giutinosa (L.) Gaertn. and Corylus avellana L) with an extensive late Quaternary fossil record in Spain as a study case. We fit 110 models with different levels of complexity under present time and tested model performance using AUC (area under the receiver operating characteristic curve) and AlCc (corrected Akaike Information Criterion) through the standard procedure of randomly partitioning current occurrence data. We then compared these results to an independent validation by projecting the models to mid-Holocene (6000 years before present) climatic conditions in Spain to assess their ability to predict fossil pollen presence-absence and abundance. We find that calibrating Maxent models with default settings result in the generation of overly complex models. While model performance increased with model complexity when predicting current distributions, it was higher with intermediate complexity when predicting mid-Holocene distributions. Hence, models of intermediate complexity resulted in the best trade-off to predict species distributions across time. Reliable temporal model transferability is especially relevant for forecasting species distributions under future climate change. Consequently, species-specific model tuning should be used to find the best modeling settings to control for complexity, notably with paleoecological data to independently validate model projections. For cross-temporal projections of species distributions for which paleoecological data is not available, models of intermediate complexity should be selected.
