Beating the bounds: how does ‘open source’ become a seed commons?

In response to ongoing plant genetic enclosures, the Open Source Seed Initiative (OSSI) is creating a ‘protected commons’ for seed. It is a project, I argue, that reflects characteristics of a growing transnational commoning movement. From the Zapatistas to seed wars, such movements draw attention to commons not simply as a resource, but as a dynamic and evolving social activity: commoning. In the US, OSSI includes 38 plant breeders, 48 seed companies and 377 crop varieties. Yet challenges remain for OSSI to gain wider legitimacy for ‘freed seed’, to build trust in a moral pledge, and to establish fair guidelines for which people and which seed can participate in making the commons. Using the metaphor of ‘beating the bounds’ – a feudal practice of contesting enclosures – I ask how OSSI defends the commons in intersecting arenas. The first way is legal, as OSSI negotiates a move from contract law toward moral economy law. Next is epistemic, as an informal breeder network revitalizes farmer knowledge, while proving more structurally able and culturally equipped to lead commoning efforts. Finally, I reflect on the nature of boundary beating itself, aided by Global South movements. Seed sovereignty perspectives suggest room for a pluriverse of commons to grow.     

Measuring subnational democracy: toward improved regime typologies and theories of regime change

Social scientists have been limited in their work by the paucity of global time series data about subnational institutions and practices. Such data could help scholars refine regime typologies, improve theories of democratization and regime change, better understand subnational democracy, and illuminate issues of development, conflict, and governance. This article addresses the lack of data by introducing 22 subnational measures from a new dataset, Varieties of Democracy. Validity tests demonstrate that the measures’ strengths outweigh their weaknesses. The measures excel in covering all subnational levels for most countries, capturing different elements of subnational elections, and including a variety of dimensions of elections and civil liberties. The measures also offer unmatched global and temporal coverage. The article demonstrates how these strengths can provide scholars with the benefits described above.     

Intra-Campaign Changes in Voting Preferences: The Impact of Media and Party Communication

An increasing number of citizens change and adapt their party preferences during the electoral campaign. We analyze which short-term factors explain intra-campaign changes in voting preferences, focusing on the visibility and tone of news media reporting and party canvassing. Our analyses rely on an integrative data approach, linking data from media content analysis to public opinion data. This enables us to investigate the relative impact of news media reporting as well as party communication. Inherently, we overcome previously identified methodological problems in the study of communication effects on voting behavior. Our findings reveal that campaigns matter: Especially interpersonal party canvassing increases voters’ likelihood to change their voting preferences in favor of the respective party, whereas media effects are limited to quality news outlets and depend on individual voters’ party ambivalence.     

Negotiating a New Social Contract for Work: An Online,Distributed Approach

A massive open online course (MOOC) entitled “Shaping the Future of Work” (offered through MITx, the Massachusetts Institute of Technology's online learning division) has been the context for a multiparty simulation designed to produce classroom negotiation results that will have social impacts. After running the course in the MOOC context three times and in face‐to‐face settings eight times, we noticed that key themes emerged. Participants have brought their own workforce perspectives to their simulation roles as employers, worker representatives, elected officials, and educators. They have called for reciprocal agreements centered on fair treatment and representation in the workplace, improved organizational performance, investments in skills and capabilities, aligned rewards and benefits for workers, and work–life balance in communities. We continue to use the simulation in the classroom and are exploring ways to expand its use. In the meantime, in this article, we discuss how the insights gleaned from this simulation could be used to crystallize and advance a new social contract at a time when the public policies, institutions, and organizational practices governing employment relations have not kept up with the dramatic changes taking place in the workforce, nature of work, and overall economy.     

Speaking Like Statesmen or Scientists: Differentiating Congressional and Administrative Views on Data

ABSTRACT

Do legislators and executives speak of data the same way when speaking about public sector data? Public management scholarship and public performance policies often emphasize data-driven decision making as the path to making government efficient and effective. Whether the public policy makers mean the same thing when they speak about data in discussions of data-driven performance and decision making is unknown. In this article, the authors present an analysis of the language of data in conversations about government performance. Two frameworks are identified for the role of data in public performance—the statesman’s and the scientist’s. A corpus-level analysis of over 30 years of government documents is used to demonstrate the differences between these two approaches. This research builds consciously on the work of previous scholars seeking to map the nuances of data-driven performance management policies in the U.S. federal government.     

Opening up to OERs: Electronic Original Sourcebook Versus Traditional Textbook in the Introduction to American Government Course

Traditional American Government textbooks are expensive and often unpopular with students. New technologies and Open Educational Resources (OERs) open up the potential for change, but questions of quality are ever present: can OERs really help students learn better, or are they just cheaper? I developed an OER based on original sources and compared student learning outcomes with the OER section to those in a free digital textbook section. While the OER I created did not work as well as I had hoped, I nonetheless developed a redesign of my course and my approach to teaching, which is the true benefit of adopting OERs.     

Data Analysis and Data Visualization as Active Learning in Political Science

While data analysis and the related skills of data management and data visualization are important skills for undergraduates in the field of political science, the process of learning these skills can also be used to develop critical thinking, encourage active and collaborative learning, and to apply knowledge gained in the classroom. Drawing on our experiences using data work in upper-level courses in International Relations and American Politics, we discuss how data work and quantitative analysis can be incorporated into subject-based (i.e., nonmethods specific) courses, and how it can also enhance critical reasoning skills. An evaluation of this approach using direct and indirect assessment is included.     

Sectoral linkages at the beginning of the 21st century: The role of Polish economy in global production structures

This paper provides a first attempt in analyzing the role of Polish economy in the production structure of the global economy in the early years of the 21st century. For the purpose of this analysis, we propose a new approach in which two most important aspects of interindustry linkages in a global input-output model are examined. Contrary to previous studies focused on output-oriented key sector analyses in post-communist CEE economies, we focus on a fundamental policy target variable – income per gross output. In order to analyze the issues in question in a dynamic framework, the empirical results are based on the 2000 and 2014 global intercountry input-output tables for the 28 EU countries as well as 15 other major countries in the world.     

Managing governance complexity and knowledge networks in transparency initiatives: the case of police open data

Public organisations are often described as being subject to types of complexity that result from the interorganisational structure of governance networks. Transparency programmes add another level of complexity due to increased information openness. However, neither the nature of this complexity nor the network management approaches needed for transparency programmes has been conceptually developed. To address this gap, this article brings together governance complexity theory and knowledge management theory. An empirical model is tested using the case of police open data with regression analysis and 22 expert interviews. The results show that institutional and environmental complexity such as budget pressures, legal-normative constraints, and task complexity exert a negative influence on police information openness. However, network knowledge management practices including developing mission focus on people and communication and overcoming organisational boundaries through interorganisational collaboration can counteract these problems of complexity.
