A time series of urban forestry in Los Angeles

There has been an increasing interest in the evolution of urban forests. This research uses historic and digital aerial photography to quantify changes in tree density in Los Angeles, California since the 1920’s. High-resolution geographic information system analysis (4 to 6 time periods) of three regions (San Fernando Valley, Hollywood, Los Angeles Basin) of Los Angeles reveals that there has not always been an increase in tree density with time. Tree densities on public and private land were highest in the 1940’s in Hollywood, while the San Fernando Valley and Los Angeles Basin experienced a near linear increase in tree density on both private and public land since the 1920’s. When historic tree density reconstructions were examined for the 15 Los Angeles city council districts from the 1920’s, 1950’s and 2006, most districts in Los Angeles have experienced a significant increase in tree density, however, there has been wide variation in tree densities among city council districts. Trees densities have generally been higher on private land since the 1920’s and currently tree densities on private land are significantly higher than on public land. Results suggest the evolution of urban forests in Los Angeles mirrors the dynamics of urban forests in desert and grassland cities. It is possible to reconstruct the development of urban forests in sections of cities using historic and contemporary aerial photography. We estimated that Los Angeles averages approximately 104 trees per hectare (82 private land, 22 public land) based on 2006 imagery at 0.3 m resolution, however, field validation suggests that we identified only 73% of trees. Although there is still space to plant trees on public land, private land owners will need to be heavily involved in order to achieve the goals of Los Angeles’ Million Tree Initiative.     

Facilitating intercultural education in majority student groups in higher education

ABSTRACT

The present article critically analyses the pedagogical efforts of two teachers to promote values education and intercultural reflection in their own educational practice. They teach in higher education in Norway and most of their students have majority backgrounds. Based on their teaching experiences with VaKE (Values and Knowledge education), the article discusses opportunities and challenges when working with values education in majority student groups. It concludes that discussing values is difficult but can be eye opening. It also raises the question of which dilemmas can prevent stereotyping and foster more complex intercultural thinking and shows that intercultural education requires a discussion of one’s own cultural position. The article highlights the teacher’s crucial role in the VaKE-process regarding the aims of intercultural values education.     

Analyzing public sentiments online: combining human- and computer-based content analysis

Recent technological developments have created novel opportunities for analyzing and identifying patterns in large volumes of digital content. However, many content analysis tools require researchers to choose between the validity of human-based coding and the ability to analyze large volumes of content through computer-based techniques. This study argues for the use of supervised content analysis tools that capitalize on the strengths of human- and computer-based coding for assessing opinion expression. We begin by outlining the key methodological issues surrounding content analysis as performed by human coders and existing computational algorithms. After reviewing the most popular analytic approaches, we introduce an alternative, hybrid method that is aimed at improving reliability, validity, and efficiency when analyzing social media content. To demonstrate the usefulness of this method, we track nuclear energy- and nanotechnology-related opinion expression on Twitter surrounding the Fukushima Daiichi accident to examine the extent to which the volume and tone of tweets shift in directions consistent with the expected external influence of the event. Our analysis revealed substantial shifts in both the volume and tone of nuclear power-related tweets that were consistent with our expectations following the disaster event. Conversely, there was decidedly more stability in the volume and tone of tweets for our comparison issue. These analyses provide an empirical demonstration of how the presented hybrid method can analyze defined communication sentiment and topics from large-scale social media data sets. The implications for communication scholars are discussed.     

Development of a Culturally Specific Career Exploration Group for Urban Chinese Immigrant Youth

A rapid increase in the number of Chinese immigrants and the specific challenges faced by low‐income Chinese immigrant youth attending urban schools warrant culturally sensitive school‐based interventions and services. However, research and services are limited for this population because of cultural biases in traditional career theories and the “model minority” myth suggesting that Asian students are excelling. The authors developed and implemented a culturally specific career exploration group for low‐income Chinese immigrant youth to address their career concerns with respect to multiple social and cultural factors and to provide social support. Implications for future program development and research are provided.     

AEDs at Your Fingertips: Automated External Defibrillators on College Campuses and a Novel Approach for Increasing Accessibility

Abstract. The use of automated external defibrillators (AEDs) increases survival in cardiac arrest events. Due to the success of previous efforts and free, readily available mobile mapping software, the discussion is to emphasize the importance of the use of AEDs to prevent sudden cardiac arrest–related deaths on college campuses and abroad, while suggesting a novel approach to aiding in access and awareness issues. A user-friendly mobile application (a low-cost iOS map) was developed at Florida State University to decrease AED retrieval distance and time. The development of mobile AED maps is feasible for a variety of universities and other entities, with the potential to save lives. Just having AEDs installed is not enough—they need to be easily locatable. Society increasingly relies on phones to provide information, and there are opportunities to use mobile technology to locate and share information about relevant emergency devices; these should be incorporated into the chain of survival.     

Interpersonal Amplification of Risk? Citizen Discussions and Their Impact on Perceptions of Risks and Benefits of a Biological Research Facility

Much risk communication research has demonstrated how mass media can influence individual risk perceptions, but lacks a comprehensive conceptual understanding of another key channel of communication: interpersonal discussion. Using the social amplification of risk as a theoretical framework, we consider the potential for discussions to function as amplification stations. We explore this possibility using data from a public opinion survey of residents living in potential locations for a new biological research facility in the United States. Controlling for a variety of key information variables, our results show that two dimensions of discussion—frequency and valence—have impacts on residents’ perceptions of the facility's benefits and its risks. We also explore the possibility that an individual's overall attitude moderates the effect of discussion on their perceptions of risks and benefits. Our results demonstrate the potential for discussions to operate as amplifiers or attenuators of perceptions of both risks and benefits.     

Factors associated with undertreatment of medical student depression

The authors measured factors associated with under-treatment of medical students' depression. They administered a cross-sectional Beck Depression Inventory and sociodemographic questionnaire to students at 1 medical school, defining their outcome measure as the use of counseling services or antidepressant medication. Of an estimated 450 available student participants in the study, 322 (71.6%) completed the questionnaire. Forty-nine students (15.2%) were classified as depressed and 10 (20.4%) reported experiencing suicidal ideation during medical school, but only 13 (26.5%) of the depressed students reported treatment. The researchers observed no difference in treatment by year in school, completion of psychiatric requirement, race, or depression severity. Treatment for depression was significantly associated with older age and personal and family histories of depression. Despite the availability of effective medications and confidential mental health services, medical students with depression are undertreated. The authors' findings support the need for targeted messages to help medical students recognize their depression and refer themselves for appropriate treatment.     

The demographic evolution of rural France (1968-1982)

"After more than a century of decline, noticeable increases in the rural population of France became apparent in the 1982 census. The spatial patterns of these changes are interpreted by comparing a set of demographic variables in the 1968-1975 and 1975-1982 intercensal periods. Migration to rural areas near many of the major cities (rurbanization) and to the southern part of France is the main demographic explanation. Using factor analysis and a hierarchical classification system the underlying demographic associations are established and the nation is differentiated into seven types. A method for estimating the probabilities of any one type occurring is also demonstrated. The timing of the demographic changes and the fundamental societal forces which have influenced them suggest that government policy has played a minor part in the evolution."     

The Polls Trends: Public Reactions to Global Health Threats and Infectious Diseases

Over the past two decades, newly emerging infectious diseaseshave developed into major global health concerns, sparking intensemedia coverage, and triggering fears of a global outbreak amongpublic health experts and authorities. This article focuseson trends in American attitudes toward these newly emerged infectiousdiseases by analyzing poll data over the past 6 years aboutissues relating to avian flu, severe acute respiratory syndrome,West Nile virus, and anthrax. The polls show that Americans’attention to news coverage seemed to be event driven, peakingwhen there were new human or animal cases, and decreasing rapidlywhen the diseases seemed to have been contained. Americans’perceptions of threats were usually the highest in the earlystages of major outbreaks. The public became more complacentwhen the outbreaks seemed to be under control. Both behavioralchanges and general knowledge remained largely constant, suggestinga limited impact of the various informational and awarenesscampaigns by governmental agencies in the wake of these pandemics.

“Where’s the human dignity in that?”: LGBTQIA + people with intellectual disability exploring sexual lives and respectful relationships

Abstract

For people with disabilities, sexuality remains a contested and restricted space. This research investigated how the Sexual Lives & Respectful Relationships (SL&RR) program might be adapted for people with intellectual disabilities who identify as LGBTQIA+. The program included co-developed materials and specifically curated narratives. It was received positively. The facilitators identifying as members of the LGBTQIA+ community was also reported as positive. While an inclusive program might be ideal, participants expressed the view that community attitudes (including those of other people with intellectual disability) might not yet be conducive to integrated human relationships programs.
