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.     

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.     

台湾的大学生对《两岸服务贸易协议》的看法

2014年3月18日,台湾的学生以及社会团体因为反对两岸服贸协议,进而占领“立法院”,并发起一连串的示威与抗议活动。本研究运用定群追踪数据,以网络民调方式访问台湾地区大三的学生对两岸服贸协议的看法。初步发现：大学生对于服贸协议的态度,受到其政党倾向、统“独”立场以及“台湾人认同”的影响。不过,本研究运用政治情绪的测量也发现：台湾的大学生对于台湾的愤怒与对中国大陆的愤怒,让他们反对两岸服贸协议,但当他们对中国大陆抱持希望时,仍然支持两岸服贸协议。因此,中国大陆的崛起及繁荣与发展,既让台湾的大学生对于台湾的现况感到愤怒,确也对中国大陆充满憧憬。     

Examining Space–Time Interaction in City-Level Homicide Data: Crack Markets and the Diffusion of Guns Among Youth

This paper examines the linkage between crack market activity and gunhomicide suggested by Blumstein (1995), who argues that the arrival ofcrack stimulated an increased availability of guns among juveniles. Thisgreater availability of guns, the argument continues, is responsible for thesharp upswing in juvenile homicide experienced in the United States in themid-1980s. Using city-level data on crack arrests and gun-related juvenilehomicide, we fit a change-point version of the Bass (1969) model ofinnovation diffusion. We find that, in most large American cities, thediffusion process for crack cocaine experienced an onset of dramatic growththat was followed by a similar, slightly slower growth in gun homicidescommitted by juveniles. We further use cluster analysis to find that thespatial patterning of the two processes is similar, starting on the East andWest Coasts and working their way toward other regions of the nation. Gunuse in homicide among slightly older offenders (ages 18–24) alsoexperienced a change at roughly the same time as the juveniles, but the rateof diffusion was considerably milder than for the younger group; offendersages 25 or older generally show no growth in gun-related homicide whatsoever. In addition, there is no detectable surge in juvenile nongun homicide activity. Based on these findings, we conclude that the crack cocaine markets–gun availability linkage is highly plausible, and we suggest directions for future research in clarifying the dynamics of the late-1980s surge in juvenile homicide.
