Designing a comprehensive system for analysis of handwriting biomechanics in relation to neuromotor control of handwriting

A comprehensive system for investigation of biomechanical and neuromuscular processes involved with producing handwriting and drawing was developed. The system included a pen-like grip measuring device that enabled the variations of finger grip force associated with writing and drawing to be measured while holding the pen in tripod grip. The pen was integrated with a digitiser tablet for recording x,ycoordinates and pressure of the nib and a motion analysis system for recording the limb and hand kinematics. It was observed that for line drawing in the y-direction of the tablet, finger forces were directly related to pen tip movement and finger forces were modulated in a repeatable and predictable fashion, while this was not the case for line drawing in the x-direction. This was evidence for longstanding assumptions. Wrist rotation was required for production of lines in the x-direction without excessive deviation. For writing tasks, it was observed that no two tasks performed by one subject share an identical writing process, not even when the writing results are (nearly) identical. The neuromuscular control apparatus is highly flexible and works in a coordinated fashion that allows production of nearly equal end-results by means of different mechanical and therefore neuromuscular processes. For spiral drawing, tremor that originates from the fingers, hand and arm was quantified with the transducer pen. Limb joint kinematics were displayed in three dimensions with colour coding of coordinate sample numbers. This method can reveal the origin of some forms of limb tremor. Pen grip force patterns during signature writing were found to be characteristic for subjects, which relate to their individual pen-hand interaction, resulting from fine control of distal joints. Variation between trials of the same subject was observed, revealing adaptations of the computational processes during writing. The potential for signature verification by means of finger force recording was explored.A comprehensive system for investigation of biomechanical and neuromuscular processes involved with producing handwriting and drawing was developed.

Social media echo chambers create serious issues for organisations

When an organisation miscommunicates with its stakeholders, they can spread their anger through social media, write Madeline Toubiana and Charlene Zietsm

First, do no harm: Evaluating resources for teaching social entrepreneurship

We reviewed two key repositories of social entrepreneurship pedagogical resources: Ashoka.org and CasePlace.org. Each provides a set of useful resources, comprising videos, syllabi, cases, readings and other resources that make it easy for instructors to design social entrepreneurship courses, modules, or programs. We caution against what we see as overenthusiasm for the topic, however, since social entrepreneurship involves tinkering with social structures, sometimes with disastrous unintended effects. We advise instructors to teach their students to think critically about social entrepreneurship initiatives, since they include the potential for harm as well as good. © Academy of Management Learning & Education

Unobtrusive Maintenance: Temporal Complexity, Latent Category Control and the Stalled Emergence of the Cleantech Sector

© 2018 John Wiley & Sons Ltd and Society for the Advancement of Management Studies Disruptive innovation changes the basis of competition within an industry and poses substantial threats for market incumbents. While researchers have focused on whether incumbents can successfully adapt, we know little about how potentially disruptive innovation may be avoided. Studying clean technology in Canada, we examine incumbent resistance when potentially disruptive technologies are seen as socially beneficial. We identify actions taken by incumbents and other socio-technical regime actors to respond to the issue while simultaneously enacting legitimate stabilizing mechanisms within the regime’s institutional infrastructure. Specifically, temporal and resource-based actions led to temporal complexity for disruptive cleantech entrepreneurs, and evaluation structuring work led to latent control of the cleantech category, privileging incumbents and resulting in unobtrusive maintenance. Our findings contribute to the disruptive innovation and institutional theory literatures by showing how disruption may be stalled by the enactment of legitimate elements of the institutional infrastructure rather than direct institutional defence

Social Innovation: Integrating Micro, Meso, and Macro Level Insights From Institutional Theory

© The Author(s) 2018. Social innovations are urgently needed as we confront complex social problems. As these social problems feature substantial interdependencies among multiple systems and actors, developing and implementing innovative solutions involve the re-negotiating of settled institutions or the building of new ones. In this introductory article, we introduce a stylized three-cycle model highlighting the institutional nature of social innovation efforts. The model conceptualizes social innovation processes as the product of agentic, relational, and situated dynamics in three interrelated cycles that operate at the micro, meso, and macro levels of analysis. The five papers included in this special issue address one or more of these cycles. We draw on these papers and the model to stimulate and offer guidance to future conversations on social innovations from an institutional theory perspective

Field or fields? Building the scaffolding for cumulation of research on institutional fields

© Academy of Management, all rights reserved. The concept of an institutional field is one of the cornerstones of institutional theory, and yet the concept has been stretched both theoretically and empirically, making consolidation of findings across multiple studies more difficult. In this article, we review the literature and analyze empirical studies of institutional fields to build scaffolding for the cumulation of research on institutional fields. Our review revealed two types of fields: exchange and issue fields, with three subtypes of each. We describe their characteristics, and subsequently, review field conditions in the extant literature and develop a typology based on two dimensions: the extent of elaboration of institutional infrastructure and the extent to which there is an agreed-upon prioritization of logics. We discuss the implications of field types and conditions for isomorphism, agency, and field change, based on a review of the literature that revealed six pathways of field change and the factors affecting them. We outline a research agenda based on our review highlighting the need for consolidation of field studies and identify several outstanding issues that are in need of further research

Organizing sustainably: Introduction to the special issue

To confront the climate crisis requires fundamental system change in order to break the convention of relentless economic exploitation of nature. In this Special Issue we extend understanding of the opportunities for an organizing perspective on sustainability in order that organization studies might contribute more effectively to the challenges of organizing sustainably. This organizing perspective is particularly sensitive to (1) a variety of forms and practices of sustainable organizing in different societal spheres and on different levels, (2) the social institutions, logics and value systems in which these forms and practices are embedded, (3) the power and politics of promoting (or blocking) sustainable organization, and (4) the ways in which work, voice, participation, and inclusion are organized and contribute to developing societal capabilities. These features formed the basis of our original call for papers and we review selected literature on sustainability, including the contribution of organization studies and the articles in this Special Issue, through this organizing perspective. In so doing we identify four key themes of a future research agenda that builds from the foundations of existing research and addresses key current limitations in both theory and practice: sustainability requires social justice; connecting local and global scale shifts; democratizing governance; and acting collectively. We conclude with some implications for our own scholarship in organization studies if we are to meet the twin challenges of the need for new theorizing in combination with devising practically relevant support for change

Valtion aluehallintovirastot ja niiden ylijohtajat: Pohjoiseurooppalainen analogia Ranskan prefeikteille

This chapter examines the closest Finnish analogy to the French function of the prefect. In Finland, since 2010, this function has been vested in the institution of the State Regional Administrative Agency (SRAA, aluehallintovirasto, ‘AVI’). There are six SRAAs, each headed by a Chief Director (ylijohtaja) nominated by the government. The study had four main findings. First, despite ambiguity in institutional terminology, classifications, boundaries and identities concerning the SRAA, one can discern few true functional or structural deficiencies. Second, the SRAA is a hybrid between an institution of its own and a territorial representative of either government ministries or government agencies, to which is related the fact that each SRAA has both responsibilities concerning its territory and nationwide responsibilities. Third, tensions between performance and institutional legitimation prevail in the institution of the SRAA, but again without serious deficiencies. Fourth, the 2010 substitution of the SRAA for the former Province comprised a radical institutional change. The 2015–2019 Finnish government intended to abolish the SRAAs, but the subsequent government abandoned that reform, and ultimately by mid-2020 it became clear that the institution of the SRAA was here to stay after all.Peer reviewe
