On Twitch.tv, the gaming-oriented live streaming platform, users interact by sharing and viewing gameplay and participating in live chats. Negativity in online gaming is often explored on a large scale using broad categories. This study offers a nuanced look at Twitch.tv communities dedicated to the Dark Souls game series to examine the descriptive and injunctive community norms surrounding both aggressive negativity and ambiguous negativity, which involves interactions where the valence is not obvious and must be interpreted based on community-specific meanings and rules. This study systematically analyzed excerpts of chats and stream recordings of 22 live streamed sessions. It found ambiguous negativity was prevalent in cases of cursing, game jargon, banter, spam, and sarcasm. Aggressive negativity was rare but manifested in exclusionary language and banter gone too far. The response of community members and collective acceptance or rejection of such negativity was not clearly defined.

The family described in this article provides an unusual opportunity to relate findings from genetic, histological, electrophysiological, psychophysical, and rehabilitative investigation. Although the total number evaluated is large (49), the known, living affected population is smaller (14), and these are spread from age 20 to age 59. As a result, the findings described above are those of a large-scale case study. Clearly, more data will be available through longitudinal study of the individuals documented in the course of this investigation but, given the slow nature of the progression in this disease, such studies will be undertaken after an interval of several years. The general picture presented to the audiologist who must rehabilitate these cases is that of a progressive cochlear degeneration that affects only thresholds at first, and then rapidly diminishes speech intelligibility. The expected result is that, after normal language development, the patient may accept hearing aids well, encouraged by the support of the family. Performance and satisfaction with the hearing aids is good, until the onset of the speech intelligibility loss, at which time the patient will encounter serious difficulties and may reject hearing aids as unhelpful. As the histological and electrophysiological results indicate, however, the eighth nerve remains viable, especially in the younger affected members, and success with cochlear implantation may be expected. Audiologic counseling efforts are aided by the presence of role models and support from the other affected members of the family. Speech-language pathology services were not considered important by the members of this family since their speech production developed normally and has remained very good. Self-correction of speech was supported by hearing aids and cochlear implants (Case 5’s speech production was documented in Perkell, Lane, Svirsky, & Webster, 1992). These patients received genetic counseling and, due to the high penetrance of the disease, exhibited serious concerns regarding future generations and the hope of a cure.

The University

This paper traces the partnership between the University of Toronto and the non-profit Local Food Plus (LFP) to bring local sustainable food to its St. George campus. At its launch, the partnership represented the largest purchase of local sustainable food at a Canadian university, as well as LFP’s first foray into supporting institutional procurement of local sustainable food. LFP was founded in 2005 with a vision to foster sustainable local food economies. To this end, LFP developed a certification system and a marketing program that matched certified farmers and processors to buyers. LFP emphasized large-scale purchases by public institutions. Using information from in-depth semi-structured key informant interviews, this paper argues that the LFP project was a disruptive innovation that posed a challenge to many dimensions of the established food system. The LFP case study reveals structural obstacles to operationalizing a local and sustainable food system. These include a lack of mid-sized infrastructure serving local farmers, the domination of a rebate system of purchasing controlled by an oligopolistic foodservice sector, and embedded government support of export agriculture. This case study is an example of praxis, as the author was the founder of LFP, as well as an academic researcher and analyst.

Untargeted Profiling

A viral development of statistical data processing, computing capabilities, chromatography-mass spectrometry, and omics technologies (technologies based on the achievements of genomics, transcriptomics, proteomics, metabolomics) in recent decades has not led to formation of a unified protocol for untargeted profiling. Systematic errors reduce the reproducibility and reliability of the obtained results, and at the same time hinder consolidation and analysis of data gained in large-scale multi-day experiments. We propose an algorithm for conducting omics profiling to identify potential markers in the samples of complex composition and present the case study of urine samples obtained from different clinical groups of patients. Profiling was carried out by the method of liquid chromatography mass spectrometry. The markers were selected using methods of multivariate analysis including machine learning and feature selection. Testing of the approach was performed using an independent dataset by clustering and projection on principal components.

Secondary School Level

The study sought to explore students' views on the utility of non-formal education in addressing the school dropout phenomenon at secondary school level. Qualitative research approach was adopted and a case study design was utilised. The population consisted of all the students in the non-formal programme at the school from which a sample of 11 students (2 male and 9 female) was selected through purposive stratified sampling technique. Data were gathered through structured in-depth interviews and focus group discussions. Non-formal education was seen to address the school dropout phenomenon by providing school drop outs with an opportunity to continue their education and hence becomes a form of empowerment. A number of challenges such as lack of adequate tuition in some subjects, lack of conducive learning environment as well as negative perception of non-formal education held by pupils in the formal stream and community members were identified. The study recommends that the Ministry of Primary and Secondary Education should review the staffing situation in schools to ensure the availability of teachers in the various subjects in the non-formal stream. Schools should make an effort to provide appropriate learning facilities for students in the nonformal stream. Furthermore, schools should conscientise their communities on the importance of non-formal education.
