Risky business: Covering slow‐onset hazards as rapidly developing news

The emerging field of risk communication has yet to thoroughly grapple with how the mass media report risk. Through a content analysis of five newspapers noted for their science reporting, newspaper coverage of four environmental hazards is compared to media coverage of more traditional risky events. In general, these slow‐to‐develop stories are reported in much the same way as more traditional disaster stories. News accounts emphasized an event orientation, framed risks in terms of human activity rather than social and political contexts, described risk in terms of harms and benefits, and relied on traditional sources. The authors then explore how this version of mass‐mediated risk might change current definitions of risk communication and how a mediated construction of risk may influence public perception of the political choices these issues raise.     

Media and the institutional perspective: U.S. and Canadian coverage of terrorism

Abstract

This paper reports data from a content analysis of television news coverage of terrorism. A proposed typology of terrorism and media coverage is tested with stories from network news in the United States and Canada. The typology posits that media coverage of terrorism depends on the act's relation to institutional power bases. The two types of terrorism outlined either seek out or avoid media coverage, depending on whether they challenge or reinforce institutional power. Because of media's interrelationship with the economic and political institutions, coverage of terrorism will take on the flavor of these institutions’ perspective. The data show that although media cover terrorist acts that are linked to U.S. institutional interests, the tone of such coverage casts uncritical perspective. The implications for the general message system of news, with particular regard to the media's contribution to international understanding, are explored.     

Notes on recent articles

An increasing number of studies in political communication focus on the “sentiment” or “tone” of news content, political speeches, or advertisements. This growing interest in measuring sentiment coincides with a dramatic increase in the volume of digitized information. Computer automation has a great deal of potential in this new media environment. The objective here is to outline and validate a new automated measurement instrument for sentiment analysis in political texts. Our instrument uses a dictionary-based approach consisting of a simple word count of the frequency of keywords in a text from a predefined dictionary. The design of the freely available Lexicoder Sentiment Dictionary (LSD) is discussed in detail here. The dictionary is tested against a body of human-coded news content, and the resulting codes are also compared to results from nine existing content-analytic dictionaries. Analyses suggest that the LSD produces results that are more systematically related to human coding than are results based on the other available dictionaries. The LSD is thus a useful starting point for a revived discussion about dictionary construction and validation in sentiment analysis for political communication.     

mtDNAprofiler: A Web Application for the Nomenclature and Comparison of Human Mitochondrial DNA Sequences,

Mitochondrial DNA (mtDNA) is a valuable tool in the fields of forensic, population, and medical genetics. However, recording and comparing mtDNA control region or entire genome sequences would be difficult if researchers are not familiar with mtDNA nomenclature conventions. Therefore, mtDNAprofiler, a Web application, was designed for the analysis and comparison of mtDNA sequences in a string format or as a list of mtDNA single‐nucleotide polymorphisms (mtSNPs). mtDNAprofiler which comprises four mtDNA sequence‐analysis tools (mtDNA nomenclature, mtDNA assembly, mtSNP conversion, and mtSNP concordance‐check) supports not only the accurate analysis of mtDNA sequences via an automated nomenclature function, but also consistent management of mtSNP data via direct comparison and validity‐check functions. Since mtDNAprofiler consists of four tools that are associated with key steps of mtDNA sequence analysis, mtDNAprofiler will be helpful for researchers working with mtDNA. mtDNAprofiler is freely available at http://mtprofiler.yonsei.ac.kr .     

Ultrafast Amplification of DNA on Plastic Microdevices for Forensic Short Tandem Repeat Analysis

The majority of microfluidic devices used as a platform for low‐cost, rapid DNA analysis are glass devices; however, microchip fabrication in glass is costly and laborious, enhancing the interest in polymeric substrates, such as poly (methyl methacrylate) (PMMA), as an inexpensive alternative. Here, we report amplification in PMMA polymerase chain reaction (PCR) microchips providing full short tandem repeat profiles (16 of 16 loci) in 30–40 min, with peak height ratios and stutter percentages that meet literature threshold requirements. In addition, partial profiles (15 of 16 loci) were generated using an ultrafast PCR method in 17.1 min, representing a ~10‐fold reduction in reaction time as compared to current amplification methods. Finally, a multichamber device was demonstrated to simultaneously amplify one positive, one negative, and five individual samples in 39 min. Although there were instances of loci dropout, this device represents a first step toward a microfluidic system capable of amplifying more than one sample simultaneously.     

High‐Throughput STR Analysis for DNA Database Using Direct PCR,

Since the Korean criminal DNA database was launched in 2010, we have focused on establishing an automated DNA database profiling system that analyzes short tandem repeat loci in a high‐throughput and cost‐effective manner. We established a DNA database profiling system without DNA purification using a direct PCR buffer system. The quality of direct PCR procedures was compared with that of conventional PCR system under their respective optimized conditions. The results revealed not only perfect concordance but also an excellent PCR success rate, good electropherogram quality, and an optimal intra/inter‐loci peak height ratio. In particular, the proportion of DNA extraction required due to direct PCR failure could be minimized to <3%. In conclusion, the newly developed direct PCR system can be adopted for automated DNA database profiling systems to replace or supplement conventional PCR system in a time‐ and cost‐saving manner.     

Analysis and counter‐policies on elderly criminals in Korea

The second counter‐policy is an establishment of a proper network of legal systems, including the establishment of accurate statistical data and well‐structured criminal law and defense systems for the elderly — comparable to the currently operative systems established to process and to deal with crimes of teenage and female offenders.

Research on indigence, health, recreation, housing and other welfare areas of the elderly is common in Korea, but research on elderly criminals is rare. Projecting that their crime rates will rise, this preliminary research was conducted in order to understand their crime status and to establish proper counter‐policies.

This research focuses on the analysis of the present elderly population and changes of their status, in addition to criminal theories and criminal trends. Analysis on criminal statistics is done through classifying criminal offenses and special offenses according to the present governmental criminal classification methods of Korea. Criminal offenses are further separated into serious and estate‐related offenses.

The result of analysis on elderly criminals in Korea indicates that the most common crimes are assaults and related offenses, including battery and bodily injuries. Most assaults or related charges were, however, not decidedly serious. Among estate‐related offenses, misappropriation and property‐damage were the most common. Among special offenses, constructional violations have the highest rate. The majority of estate related offenses were less serious and produced less than W‐ 1,000,000 (approximately $1150 US dollars) in damages.

Destruction of traditional society is the major source of criminal activities. While younger generations demand less authoritarian and more interdependent relationships, the elderly insist upon adhering to their traditional ways of thinking. The elderly commit crimes out of the animosity and exasperation created from a perceived incompatibility with modern society. Their diminishing social and family hierarchies, along with carelessness and lack of recreation, lead the elderly into feeble or fatuous life styles, eventually leading to various offenses.

There is no simple solution to prevent the elderly from committing crimes since complex social and/or personality problems cause these deviant behaviors. The government needs to understand the overall problems and establish necessary counter‐policies with regard to the elderly. Even if their present crime rates seem insignificant now, the numbers are growing rapidly.

Conclusively, the first counter‐policy is to eliminate the source of the problems. Some specific policies that can be adopted to eliminate these sources include the expansion of employment and related educational opportunities to improve their economic conditions; realignment of medical benefit systems; broader access to effective recreational activities through volunteer and other civic programs; and social adjustment programs that can guide the elderly to better adjust to the evolving social changes.     

Crime and punishment in the soviet union and the united states: 1986–19901

A relatively recent development in the comparative criminology literature concerns cross‐national comparisons of criminal sentencing practices (e.g., Lynch, 1993). While there are now several studies comparing sentencing practices and lengths, there is a particular shortage of studies that examine the disposition of serious criminal cases through several stages of the criminal justice process. Specifically, there is a shortage of information concerning this issue in Russia and the former Soviet Union. To address this limitation, we present data on the police and court disposition of violent criminal cases in the former Soviet Union during the period of 1986 to 1990. For comparative purposes, comparable data from recent studies of criminal case dispositions in the United States are presented. Implications of the findings are discussed.
