Deep Participation in Underserved Communities: A Quantitative Analysis of Hearken’s Model for Engagement Journalism

ABSTRACT

Hearken is a proprietary news engagement platform growing in popularity. Under the Hearken approach, audience members are invited to participate in the newsmaking process. Hearken strives to assist news organizations in providing local and hyperlocal content that meets audience needs and demands while preserving elements of the journalist’s role as gatekeeper. Hearken has also worked to help news organizations reach underrepresented populations with mixed results per its own anecdotal analyses. This study employs a quantitative content analysis comparing one year’s worth of coverage at four different local NPR affiliates in the United States to provide a breakdown of Hearken content versus traditional reporter-driven content in the following four categories: emphasis on hyperlocal coverage, story topic prevalence within local and hyperlocal coverage, emphasis on coverage of underrepresented communities, and story topic prevalence within coverage of underrepresented communities. Findings reveal listener-driven Hearken content favors hyperlocal news on lifestyle issues while reporter-driven stories emphasize state-level governance and politics as well as local crime. These indicate a stark contrast between the content audiences want and that which journalists tend to report. The nuanced normative implications, possibilities and limitations of Hearken’s model of “deep participation” are addressed in some detail.     

QTL analysis for some quantitative traits in bread wheat

Quantitative trait loci (QTL) analysis was conducted in bread wheat for 14 important traits utilizing data from four different mapping populations involving different approaches of QTL analysis. Analysis for grain protein content (GPC) sug- gested that the major part of genetic variation for this trait is due to environmental interactions. In contrast, pre-harvest sprouting tolerance (PHST) was controlled mainly by main effect QTL (M-QTL) with very little genetic variation due to environmental interactions; a major QTL for PHST was detected on chromosome arm 3AL. For grain weight, one QTL each was detected on chromosome arms 1AS, 2BS and 7AS. QTL for 4 growth related traits taken together detected by different methods ranged from 37 to 40; nine QTL that were detected by single-locus as well as two-locus analyses were all M-QTL. Similarly, single-locus and two-locus QTL analyses for seven yield and yield contributing traits in two populations respectively allowed detection of 25 and 50 QTL by composite interval mapping (CIM), 16 and 25 QTL by multiple-trait composite interval mapping (MCIM) and 38 and 37 QTL by two-locus analyses. These studies should prove useful in QTL cloning and wheat improvement through marker aided selection.     

Investigating populations via penguins and their poo!

We describe an activity that introduces students to population modelling, enables them to use estimates obtained from a sample to infer back to the population, and understands how the findings are translatable via penguins and their poo!     

Evidence-based digital literacy class for older,low-income African-American adults

Based on our community engagement project involving 47 older, low-income African-American adults from a senior community center, this study analyzes how an underserved population acquires knowledge and skills related to digital technologies. We discuss the conceptualization, implementation, and evaluation of a weekly, four-month long computer class for members of the senior community center. Our mixed-method research shows the importance of taking into account both the multidimensional nature of adult learning and the social and cultural contexts in which learning occurs when working with underserved adult populations. Findings from our formative and evaluative research offer insights into changes in the computer class participants’ attitudes toward and perspectives on key digital literacy issues including security and privacy online and online information verification. Scholarly and policy implications are discussed in the context of digital competency and adult learning for marginalized populations.

Sexually Dimorphic Tridimensionally Preserved Pterosaurs and Their Eggs

<正>The pterosaur record is generally poor,with little information about their populations,and pterosaur eggs are even more rare,with only four isolated and flattened eggs found to date.Dr.WANG Xiaolin,Institute of Vertebrate Paleontology and Paleoanthropology(IVPP)of the Chinese Academy of Sciences(CAS),and his team revealed a new pterosaur-rich area with potentially thousands of bones,including tridimensionally preserved male and female skulls and eggs discovered together for the fi rst time in the Early Cretaceous deposit of the TurpanHami Basin,south of the Tian Shan Mountains in Xinjiang Uygur Autonomous Region,northwestern China.On June 6,the researchers reported online a population of a new sexually dimorphic pterosaur species(Hamipterus tianshanensis gen.et sp.nov.),with five exceptionally well-preserved three-dimensional eggs in Current Biology,providing new and important evidence regarding male and     

对当前我国城市少数民族流动人口问题的思考

城市少数民族流动人口问题是一个综合性的社会问题,它已经成为我国城市化进程中必须认真研究的重大课题。城市要强调民族多元文化存在的不可避免性,采取多种形式构建不同民族、不同文化互相沟通的平台;要落实国家民族平等政策,使少数民族流动人口融入城市社区化管理;要解决少数民族流动人口在城市生活中的难题,保障其合法权益;要培育各民族对祖国的认同感和凝聚力,以达到各民族之间互相包容、和谐共处、共同发展之目的。     

Long Distance Relationships: Assessing the Library Service Needs of Rural Students in eLearning Courses

ABSTRACT

In states with limited road accessibility, rural students can feel isolated from library services. This article explores the creation, implementation, and results of an on-going longitudinal study assessing the library service needs of rural students in eLearning courses. To align with current practices in online pedagogies, including the Association of College and Research Libraries' Standards for Distance Learning Library Services and recent revisions to the Framework for Information Literacy for Higher Education, this survey has been designed to help the library identify and improve services to enhance rural student success.     

Moving Beyond the Lecture: Inspiring Social Justice Engagement through Counter-Story Using Case Study Pedagogy

Abstract

The paper examines participant perceptions of the effectiveness of using case studies with college students (undergraduate – doctoral) to teach social justice and educational equity. Findings indicate that participants who identified with the characters in the cases were able to draw connections between the case and their own personal experiences. They felt the cases broadened their understanding of the topics and increased their sense of empathy and their commitment to principles of social justice.
