Assessing a hyperspectral image analysis system to study tumor and immune cell spatial organizations within lung tumor microenvironments
Creators: name: Kung, Sonia H.Y.
Publisher: name: University of British Columbia
Year: 2018

description: Lung cancer is the leading cause of cancer-associated death worldwide. To improve clinical management, biological discovery underlying disease pathogenesis and improved sensitivity of early detection imaging modalities are required. Presently, therapeutic targeting immune components of the tumor microenvironment led to immunotherapies, potent therapeutic agents revolutionizing clinical practice. Increasingly recognized, the native spatial organization of tumor microenvironment immune cells could potentially serve as a surrogate for predicting prognosis and stratifying tumor immunogenicity. However, conventional methods, including histopathology and genomic profiling, are limited in measuring such parameters. Image analysis systems are being tested for these applications, but further development and optimization is required before clinical adoption. Dr. Calum MacAulay and Dr. Martial Guillaud’s research team at the British Columbia Cancer Research Centre (BCCRC) developed a novel hyperspectral image analysis system capable of spatially profiling tumor microenvironments in situ. Herein, this thesis reports the workflow optimization of this system prototyped with the lung adenocarcinoma (AC) microenvironment. This study was conducted with 21 primary lung AC. Adjacent tumor sections were stained for nuclei with hematoxylin and markers of tumor-infiltrating lymphocytes (CD3, CD79a, CD8) or adaptive immune resistance (PD1, PDL1, CD8) by multiplex immunohistochemistry. After a lung pathologist identified areas of interest on tissue sections, five representative regions within each area were imaged. Image stacks of sixteen different illumination wavelengths (from 420 to 720 nm) were then processed by spectral unmixing, segmented, and immunohistochemical marker positivity thresholds applied. Processed two-dimensional images were quantified for cell types and neighboring cell type spatial correlations. Additionally, three lung AC within this cohort were selected to test workflow of image registration software to interpolate cell spatial distributions between sections. The system was able to determine immune cell-to-cell spatial correlations and distribution within and across sections. Furthermore, technical factors were identified that affected the workflow of this system, including staining, image acquisition, segmentation, specialized equipment, and sampling strategy. Here we describe a valuable platform to quantitatively and spatially profile tumor heterogeneity that could then be used to correlate with lung cancer prognosis and treatment outcomes, although further optimization of this method is required.

description: We analyse the properties of the host galaxy of the optically dark gamma-ray burst (GRB) 020819 (z = 0.41) and discuss the possible implications in the context of "dark" GRBs. We present g'r'i'z'JHK photometry of the host galaxy and fit the broad spectral energy distribution including the public Spitzer IRAC data using stellar population models. The broad spectral energy distribution (SED) indicates a high extinction, A_V ~ 1.8 - 2.6 mag, for this relatively massive galaxy. This is the highest global extinction for a GRB host galaxy with a robust spectroscopic redshift. The properties of the host galaxy are indicative of dusty, intense star-formation, which differ from those of the current sample of GRB hosts. This implies that the dust extinction is one of the main reasons for the darkness of low-redshift bursts and that the long GRB host population is far more diverse than previously anticipated.

description: Spitzer Space Telescope Infrared Array Camera (IRAC) imaging provides an opportunity to study all known morphological types of galaxies in the mid-IR at a depth significantly better than ground-based near-infrared and optical images. The goal of this study is to examine the imprint of the de Vaucouleurs classification volume in the 3.6 micron band, which is the best Spitzer waveband for galactic stellar mass morphology owing to its depth and its reddening-free sensitivity mainly to older stars. For this purpose, we have prepared classification images for 207 galaxies from the Spitzer archive, most of which are formally part of the Spitzer Survey of Stellar Structure in Galaxies (S^4G), a Spitzer post-cryogenic ("warm") mission Exploration Science Legacy Program survey of 2,331 galaxies closer than 40 Mpc. For the purposes of morphology, the galaxies are interpreted as if the images are {\it blue light}, the historical waveband for classical galaxy classification studies. We find that 3.6 micron classifications are well-correlated with blue-light classifications, to the point where the essential features of many galaxies look very similar in the two very different wavelength regimes. Drastic differences are found only for the most dusty galaxies. Consistent with a previous study by Eskridge et al. (2002), the main difference between blue light and mid-IR types is an approximately 1 stage interval difference for S0/a to Sbc or Sc galaxies, which tend to appear "earlier" in type at 3.6 microns due to the slightly increased prominence of the bulge, the reduced effects of extinction, and the reduced (but not completely eliminated) effect of the extreme population I stellar component. We present an atlas of all of the 207 galaxies analyzed here, and bring attention to special features or galaxy types that are particularly distinctive in the mid-IR.

They have claimed that their protocol is secure against adversarial attacks and also provides forward secrecy. In this paper we will show that the proposed protocol does not have proper security features. A powerful and practical attack is presented on this protocol whereby the whole security of the protocol is broken. Furthermore, Yeh et al. protocol does not assure the untraceabilitiy and backward untraceabilitiy aspects. Namely, all past and next transactions of a compromised tag will be traceable by an adversary.

Food Security and Poverty

description: The Food and Agriculture Organization (FAO) projects the global population to reach 9.7 billion by 2050. As such, food demand is expected to increase by 70% to meet food and nutritional security of the expanding population. Globally hunger is widely prevalent in the Africa, South Asia and in some Oceania islands. Therefore, population expansion and rapid urbanisation, coupled with the effects of the three Cs – COVID-19, climate change, and conflicts – are impacting food security in most of these regions. By 2050, 68% of the global population is anticipated to live in cities resulting in rising food prices, unemployment, and environmental degradation through massive accumulation of organic wastes, with only a very small proportion of it appropriately recycled in developing countries. Increasing income of urban dwellers has significantly increased the demand for crop and animal products, while lack of cost-efficient inputs such as fertilisers and feeds is constraining crop and livestock productivity. Ironically 33% of the food produced globally never manages to feed the people due to various post-harvest losses. These diverse and interlinked developmental challenges call for innovative solutions to address them. Use of insects such as black soldier fly, Hermetia illucens, for recycling organic wastes into nutrient-rich organic fertilisers for crop productivity, while also supplying high-quality insect biomass which is rich in crude proteins, fats, gross energy, well-balanced amino acids and vitamins for the feed sector to enhance livestock productivity, is one of these approaches. This is an innovative, eco-friendly and circular solution that contributes to environmental sustainability (mitigation of waste), food security (enhanced crop and livestock production) and has the potential to contribute to critically needed employment for youth and women in Africa, South Asia and the Pacific Islands. Furthermore, the high quality and locally produced insect protein and insect-based organic fertilisers can be excellent substitutes for often imported feed protein additives and synthetic fertilisers, and have the potential to reduce the import bills of several developing and underdeveloped nations.

description: The purpose of this study is to examine the opinions of students who study at Balıkesir University Faculty of Sports Sciences against violence and misconduct in sport and to determine their level of interest in sporty events. Students studying at Balıkesir University Faculty of Sport Sciences participated in the research in the 2020-2021 academic year. A total of 385 students, 50.4% (n=194) male and 49.6% (n=191) female, participated in the research. A questionnaire developed by Şeker (2011) was used to determine the views of the students participating in the research on violence and undesirable behaviors in sports. The obtained data were analyzed with (SPSS) 26.0 for Windows and presented in tables. Personal information variables (age, gender, etc.), frequency and standard deviation, arithmetic mean and chi-square analyzes were used in the analysis of the data. The level of significance in the analyzes was set as 0.05. As a result of this study; It was found that the majority of male and female students studying at Balıkesir University Faculty of Sports Sciences did not approve of violent acts and undesirable behaviors in sports. It can be said that male students have a higher tendency towards violence and unwanted behaviors in sports than female students.

description: We are carrying out a detailed 2D spectroscopic study of the central 210 pc X 130 pc of the blue compact dwarf (BCD) galaxy NGC5253. This contribution presents the ionization conditions and chemical abundance patterns for the different kinematic components of the ionized gas detected in our previous work. All the kinematic components present an excess in nitrogen abundance. In particular, the broad velocity component has larger excess than the narrow one by a factor of ~1.4+-0.4 which is consistent with a scenario for the Giant HII Region where the broad component of the emission lines traces the material expelled by the two central Super Star Clusters while the narrow one is associated to previously existing ionized gas.

title: Attitude-behaviour Gap in Green Consumerism among Men: An Exploratory Analysis
Creators: name: Gajewski, Jessica
Publisher: name: The University of East London
Year: 2018

description: 2018 dissertation for MSc. International Business Management. Selected by academic staff as a good example of a masters level dissertation. Purpose – Firstly, the purpose of the paper is to investigate adult male consumer’s attitude towards the environment and green products. Furthermore, it aims to explore the relationship between a positive environmental attitude and green purchase behaviour. Ultimately it aims to explore the factors affecting the attitude-behaviour gap in green consumerism in the context of adult male consumers. 
Design/Methodology/Approach – The research design is exploratory in nature and an interpretivist approach was followed. The primary data and qualitative approach of the study has enabled the researcher to get insight into participant’s attitudes and behaviours.  A total of eleven in-depth semi-structured interviews were conducted to successfully answer the research questions guiding the research. 
Findings – Findings show that adult male consumers show a positive attitude towards the environment and green products. Notwithstanding, the study showed that participants did not purchase green products. Factors found to impede green purchase behaviour were: lack of trust, cynicism, consumer effectiveness, price, availability/accessibility, information, time, convenience, and habit/familiarity.
Research Implications – The study has found that there is an attitude-behaviour gap in green consumerism amongst male consumers and further identified key barriers, offering a plausible explanation as to what factors influence the inconsistency. 
Practical Implications – The results have practical implications for policy makers, executives and marketing professionals to frame and implement strategies to promote and encourage green purchasing among adult male consumers.  
Originality/Value – The study addresses a gap in the literature. While the attitude-behaviour gap has been studied previously, this study is context-specific as it focusses on adult male consumers and contemporary.

description: Scatterer induced modal coupling and the consequent mode splitting in a whispering gallery mode resonator is demonstrated in aqueous environment. The rate of change in splitting as particles enter the resonator mode volume strongly depends on the concentration of particle solution: The higher is the concentration, the higher is the rate of change. Polystyrene nanoparticles of radius 50nm with concentration as low as 5x10^(-6)wt% have been detected using the mode splitting spectra. Observation of mode splitting in water paves the way for constructing advanced resonator based sensors for measuring nanoparticles and biomolecules in various environments.

Sub-Keplerian accretion onto circumstellar disks

description: Models of the formation, evolution and photoevaporation of circumstellar disks are an essential ingredient in many theories of the formation of planetary systems. The ratio of disk mass over stellar mass in the circumstellar phase of a disk is largely determined by the angular momentum of the original cloud core from which the system was formed. While full 3D or 2D axisymmetric hydrodynamical models of accretion onto the disk automatically treat all aspects of angular momentum, this is not so trivial for 1D and semi-2D viscous disk models. Since 1D and semi-2D disk models are still very useful for long-term evolutionary modelling of disks with relatively little numerical effort, we investigate how the 2D nature of accretion affects the formation and evolution of the disk in such models. A proper treatment of this problem requires a correction for the sub-Keplerian velocity at which accretion takes place. We develop an update of our semi-2D time-dependent disk evolution model to properly treat the effects of sub-Keplerian accretion. The new model also accounts for the effects of the vertical extent of the disk on the accretion streamlines from the envelope. The disks produced with the new method are smaller than those obtained previously, but their mass is mostly unchanged. The new disks are a few degrees warmer in the outer parts, so they contain less solid CO. Otherwise, the results for ices are unaffected. The 2D treatment of the accretion results in material accreting at larger radii, so a smaller fraction comes close enough to the star for amorphous silicates to be thermally annealed into crystalline form. The lower crystalline abundances thus predicted correspond more closely to observed abundances than did earlier model predictions. We argue that thermal annealing followed by radial mixing must be responsible for at least part of the observed crystalline material.

description: Recently much attention has being attracted to the problem of limitations on the attainable intensity of high power lasers [A.M. Fedotov {\it et al.} Phys. Rev. Lett. \textbf{105}, 080402 (2010)]. The laser energy can be absorbed by electron-positron pair plasma produced from a seed by strong laser field via development of the electromagnetic cascades. The numerical model for self-consistent study of electron-positron pair plasma dynamics is developed. Strong absorption of the laser energy in self-generated overdense electron-positron pair plasma is demonstrated. It is shown that the absorption becomes important for not extremely high laser intensity $I \sim 10^{24}$ W/cm$^2$ achievable in the nearest future.

description: Flavour isolation is critical for the flavour industry. Isolation methods, such as extraction, are used to prepare samples for chemical analysis, ensuring a product’s safety and authenticity. Extraction is also used to create natural flavourings that are used to impart an enjoyable smell and taste to foods. This work evaluates the extraction efficiency (EE) of two small-scale sample preparation techniques. Using this data, a machine learning model predicting the extraction efficiency of odorants was built using their physical-chemical properties, i.e. vapour pressure (VP) and the octanol:water partition coefficient (LogP), as well as the sample matrix composition. The model gives the analyst the ability to select the most appropriate extraction technique for their purpose. Historical work showed that there is no one perfect technique for flavour extraction [1]. This conclusion still holds true for the more modern techniques investigated here. For example, there is a considerable decrease in extraction efficiency for Solvent Assisted Flavour Evaporation (SAFE) when lipid is present in the extraction matrix. In fact, SAFE and Solid Phase Microextraction (SPME) both have low recoveries for volatile, hydrophilic compounds when used for sample preparation. Adapting the machine learning workflow to predicting the extraction efficiency of – potentially – any raw material would be a useful tool for the flavour industry. To test the application of this model to real-world raw material analysis, data on the extraction efficiency of ginger root using one of three isolation methods (CO2 extraction, vacuum distillation, percolation) is currently being gathered.

description: Der Beitrag präsentiert die Ergebnisse einer Studie, die sich mit der Integration von Online-Self-Assessments (OSAs) in den Beratungsalltag befasst. Trotz vorhandener Empfehlungen zur Einbindung von OSAs in die Beratungspraxis besteht bisher Unklarheit darüber, ob und wie Beratungspersonen OSAs tatsächlich nutzen und welche Vor- und Nachteile mit ihrer Anwendung im Beratungskontext verbunden sind. In einem ersten qualitativen Teil beschäftigt sich die Studie in mehreren Fokusgruppendiskussionen mit den Erfahrungen und Perspektiven von Beratungspersonen im Umgang mit OSAs. Die Ergebnisse zeigen, dass OSAs von den Beratungspersonen als wertvolle Ressource wahrgenommen werden, die vielfältige unterstützende Funktionen wie beispielsweise zur Anregung der Selbstreflexion oder zur Unterstützung der Entscheidungsfindung bieten und in Form von sehr unterschiedlichen Nutzungsszenarien in die Beratungspraxis eingebunden werden. Durch die Nutzung von OSAs erhalten Beratungspersonen zusätzliche Informationen über ihre Klient*innen, die eine differenziertere und gezieltere Beratung ermöglichen oder können Informationen z.B. über Studiengänge individualisiert für Klient*innen aufbereitet zur Verfügung stellen. Dabei zeigen sich Unterschiede in der zeitlichen und thematischen Einbindung von OSAs in der Beratungspraxis abhängig von Zielgruppe, Beratungsanlass und individueller Präferenzen der Beratungsperson. Jedoch stehen Beratungspersonen auch vor Herausforderungen bei der Einbindung von OSAs in ihren Beratungsalltag. So stellen OSAs oft durch ihre lange Bearbeitungszeit hohe Anforderungen an die Motivation der Nutzer*innen oder lassen sich häufig nicht modular bearbeiten. Gerade die Einbindung einzelner Module und Teilaufgaben in Abstimmung mit den Anliegen der Ratsuchenden stellt aber ein attraktives Nutzungsszenario für viele Berater*innen dar. Aus den berichteten Herausforderungen lassen sich wichtige Gestaltungsempfehlungen für die Entwicklung oder Überarbeitung von OSAs ableiten. Der zweite quantitativen Teil der Studie untersucht, inwieweit sich die in den Fokusgruppen erarbeiteten Ergebnisse zur Integration von OSAs in die Beratungspraxis generalisieren lassen und untersucht zudem, welche Gestaltungsempfehlungen sich für OSAs aus Sicht von Beratungspersonen als zentral herausstellen. Die Ergebnisse der Studie liefern wertvolle Erkenntnisse für die Praxis der Beratung. Sie verdeutlichen die Potenziale von OSAs als unterstützendes Instrument für Beratungspersonen und stellen verschiedene mögliche Nutzungsszenarien für die Beratungspraxis vor. Gleichzeitig zeigen sie jedoch auch Herausforderungen bei der Integration von OSAs in den Beratungsalltag.

Pre-diagnosis morbidity related to health care utilization in young women with breast cancer : a matched case-control study
Creators: name: Dunn, Julia
Publisher: name: University of British Columbia
Year: 2018

description: Background- Early-onset breast cancer is the leading cause of cancer deaths in Canadian women aged 30-39. There is much that is not known about what causes this disease. Many of the potential risk factors associated with this disease have strong hormonal, inflammatory or immunologic mechanisms, and may be reflected in morbidity prior to diagnosis. Research Question- This study addresses the question: Is morbidity in the five years prior to diagnosis associated with an increased risk of early-onset breast cancer? The primary objective of this study is to describe the extent and patterns of non-cancer morbidity in women diagnosed with breast cancer by age 40, and to compare them with similarly-aged women without a breast cancer by that age. Methods- A total of 1132 female breast cancer patients diagnosed in British Columbia from 1999 to 2008 inclusive were identified through the provincial cancer registry; 1302 female birth year-matched comparators were randomly selected from the provincial health insurance registry. Linked provincial registry, clinical, and healthcare administrative data were used to examine the morbidity experience of subjects for five years before the breast cancer diagnosis or matched date among controls. Morbidity was measured using Johns Hopkins ACG System Aggregated Diagnostic Group (ACG) codes. A multivariate conditional logistic regression model estimated the association between ACG grouping and breast cancer incidence using a one-tailed significance level of α = 0.05. Results- Five (pregnancy, prevention, signs and symptoms/major, unstable orthopedic and stable eye) of 32 ACGs were statistically significantly higher among women with breast cancer than the population sample in at least two of the five years prior to diagnosis. The ACG for asthma produced results of interest. The majority of significant results were observed two to three years preceding diagnosis. Discussion- The increased rate of major signs and symptoms, and asthma, in particular, among young women with breast cancer may point to important underlying risks in this population. Given the number of breast cancer risk factors that have strong associations with hormonal mechanisms, such as reproductive health, hormonal conditions may determine whether lifestyle and other risk factors lead to carcinogenesis.

description: This paper is part of a multi-species survey of line emission from the molecular gas in the circum-nuclear disk (CND) of the Seyfert 2 galaxy NGC1068. Single-dish observations have provided evidence that the abundance of silicon monoxide(SiO) in the CND of NGC1068 is enhanced by 3-4 orders of magnitude with respect to the values typically measured in quiescent molecular gas in the Galaxy. We aim at unveiling the mechanism(s) underlying the SiO enhancement. We have imaged with the IRAM Plateau de Bure interferometer the emission of the SiO(2-1) and CN(2--1) lines in NGC1068 at 150pc and 60pc spatial resolution, respectively. We have also obtained complementary IRAM 30m observations of HNCO and methanol (CH3OH) lines. SiO is detected in a disk of 400pc size around the AGN. SiO abundances in the CND of (1-5)xE-09 are about 1-2 orders of magnitude above those measured in the starburst ring. The overall abundance of CN in the CND is high: (0.2-1)xE-07. The abundances of SiO and CN are enhanced at the extreme velocities of gas associated with non-circular motions close to the AGN (r<70pc). Abundances measured for CN and SiO, and the correlation of CN/CO and SiO/CO ratios with hard X-ray irradiation, suggest that the CND of NGC1068 has become a giant X-ray dominated region (XDR). The extreme properties of molecular gas in the circum-nuclear molecular disk of NGC1068 result from the interplay between different processes directly linked to nuclear activity. Whereas XDR chemistry offers a simple explanation for CN and SiO in NGC1068, the relevance of shocks deserves further scrutiny. The inclusion of dust grain chemistry would help solve the controversy regarding the abundances of other molecular species, like HCN, which are under-predicted by XDR models.

description: This document comprises a literature review, in the form of a
      meta-ethnography, a research paper, using Grounded Theory methodology and
      a Critical Appraisal of the research process. Muslims may be considered to
      hold a unique worldview, with regards to the existence of the physical and
      metaphysical world. It was of interest to explore this epistemology within
      the context of therapy, specifically in relation to practitioners’
      conceptualisations of, and processes used to alleviate emotional distress
      experienced by Muslims.

      Section one, the meta-ethnography considers Muslim practitioners’
      conceptualisations of emotional distress including both spiritual and
      non-spiritual explanatory models of emotional distress. Six papers were
      included for the review. Three themes emerged from the analysis: spiritual
      causes, non-spiritual causes and the impact on clinical work. Findings are
      presented with supporting first-order quotations and are discussed in
      terms of the clinical

      implications and limitations of the literature reviews. Suggestions for
      further research are made.

      Section two presents a Grounded Theory which shows and explains processes
      used by Muslim practitioners, in alleviating emotional distress of British
      Muslims, outside mainstream mental health services. 14 interviews took
      place with nine participants, who identified as holding a role in
      alleviating emotional distress within the British Muslim community. Three
      key components of the model are presented, practitioners’
      conceptualisation of Islam and wellbeing, engaging a diverse range of
      British Muslim individuals and therapeutic processes used to alleviate
      emotional distress. Findings are discussed in terms of the clinical
      implications of the model with an acknowledgement of the limitations of
      the research findings. Suggestions for future research are made.

      The third and final section, the Critical Appraisal, summarises the
      findings of the

      previous sections. Strengths and weaknesses of the overall paper are
      acknowledged, and the researcher offers a personal reflection upon the
      influence of their epistemic position on the conduct of the research.

description: Abstract
In a time when the world economy is undergoing unprecedented change and disruption, the role of market orientation, digital orientation or business agility becomes even more important and necessary, especially the relationship of these factors with the marketing performance of the business is a topic of great interest. This study aims to determine the impact of factors affecting marketing performance including market orientation, digital orientation. It also examines the mediating role of business agility in the relationship between market orientation, digital orientation and marketing performance. The study uses a linear structural model (SEM) regression analysis method based on data including 216 surveys from CEOs, directors and senior managers in enterprises. Research results show that market orientation and digital orientation have a direct and positive impact on marketing performance. Along with that, market orientation and digital orientation also positively affect business agility, and these two factors also indirectly affect marketing performance through the intermediary factor of business agility. These findings of the study are the basis for proposing a number of implications and solutions to help businesses improve marketing performance in order to optimize operational results.
Alpha effect due to buoyancy instability of a magnetic layer

description: A strong toroidal field can exist in form of a magnetic layer in the overshoot region below the solar convection zone. This motivates a more detailed study of the magnetic buoyancy instability with rotation. We calculate the alpha effect due to helical motions caused by a disintegrating magnetic layer in a rotating density-stratified system with angular velocity Omega making an angle theta with the vertical. We also study the dependence of the alpha effect on theta and the strength of the initial magnetic field. We carry out three-dimensional hydromagnetic simulations in Cartesian geometry. A turbulent EMF due to the correlations of the small scale velocity and magnetic field is generated. We use the test-field method to calculate the transport coefficients of the inhomogeneous turbulence produced by the layer. We show that the growth rate of the instability and the twist of the magnetic field vary monotonically with the ratio of thermal conductivity to magnetic diffusivity. The resulting alpha effect is inhomogeneous and increases with the strength of the initial magnetic field. It is thus an example of an "anti-quenched" alpha effect. The alpha effect is nonlocal, requiring around 8--16 Fourier modes to reconstruct the actual EMF based on the actual mean field.

Youth perspectives on cyberbullying and social media platforms : teen agency, interactivity, and social cognition
Creators: name: Chris-Iwuru, Kesiena
Publisher: name: University of British Columbia
Year: 2018

description: This research examines how social media platforms have reconfigured traditional notions of social interaction and specifically how a sample of youth view these platforms in light of problems with cyberbullying. The research design included two primary questions: 1) How do social media platforms reconfigure social interaction and means by which youth perceive and understand these platforms? 2) What role does social cognition play in youth perspectives of online identities and interactions in relation to cyberbullying? The participants included nine Grades 10-12 students (4 males and 5 females), aged between 16-21 years. The research site was an independent high school located in the Lower Mainland of British Columbia, Canada. Actor-network theory and optimal distinctive theory (Brewer, 1991; Latour, 2005) formed the theoretical perspective for analyzing, discussing and the presentation of the research study findings. Data were collected through ethnographic techniques, including observations, artefacts (documents, etc.), and interviews (focus group). The following thematic findings were derived from data analysis: Interacting with and through content; Connectedness and reduced telepresence; Platform-culture; Growing up online; Assemblage: Self as assimilated; Assemblage: Identity as fluid and layered; External observer: Recalling social schema; Immersed-bystanders: Imposing social schema; and Aggressive coping to the self as target. Given a separate parallel state of identity, users are challenged to maintain acceptable or appropriate behaviour. The findings of this study provide helpful insights into why online antisocial behaviour and cyberbullying become pervasive and toxic. The implications and significance of the research findings have relevance for educators on how best to engage and understand teenagers in these spaces, with new and effective measures to examine instances of conflict and antisocial behaviour online. For social media companies and startups, it provides an insight into the nuanced mode and context of interaction prevalent within these platforms and the resulting impact on how individuals, the collective, and the platform itself all exert influence on each other.

description: Ecological communities exhibit pervasive patterns and inter-relationships between size, abundance, and the availability of resources. We use scaling ideas to develop a unified, model-independent framework for understanding the distribution of tree sizes, their energy use and spatial distribution in tropical forests. We demonstrate that the scaling of the tree crown at the individual level drives the forest structure when resources are fully used. Our predictions match perfectly with the scaling behaviour of an exactly solvable self-similar model of a forest and are in good accord with empirical data. The range, over which pure power law behaviour is observed, depends on the available amount of resources. The scaling framework can be used for assessing the effects of natural and anthropogenic disturbances on ecosystem structure and functionality.

ABRACADABRA : the effectiveness of a computer-based reading intervention program for students at-risk for reading failure, and students learning English as a second language
Creators: name: Flis, Ashley
Publisher: name: University of British Columbia
Year: 2018

description: This study examined the effectiveness of ABRACADABRA (ABRA). ABRA stands for A Balanced Reading Approach for CAnadians Designed to Achieve Best Results for All. This web-based literacy tool was used to target the literacy skills within two groups: grade 1 students who are at risk for reading failure (at-risk group), and students who speak English as a second language (ESL group). One hundred four students were selected to participate in the study within a school district in Ontario. In four elementary schools, students from ten grade 1 classrooms participated. Eighty-two of these students participated in the at-risk group and 22 students participated within the ESL group. Upon meeting eligibility through a screening process with the Dynamic Indicators of Basic Early Literacy Skills measure (DIBELS), participants were matched and assigned to one of two conditions: treatment (students received ABRA and regular literacy instruction) and control (students received regular literacy instruction) based on the students’ total DIBELS score. Literacy skills were assessed before and after the intervention program by six standardized assessments. Measures included: Word Attack and Letter Word Identification subtests from the Woodcock-Johnson III Tests of Achievement (Woodcock, McGrew, & Mather, 2001); Blending and Elision subtests from the Comprehensive Test of Phonological Processing (CTOPP: Wagner, Torgesen & Rashotte, 1999); and Sight Word Efficiency and Phonetic Decoding Efficiency subtests from the Test Of Word Reading Efficiency (TOWRE: Torgesen, Wagner, & Rashotte, 1999). These assessed: phonics, phonological awareness, and word reading skills. The intervention was conducted over a ten-week period, four days per week for twenty-minutes per day. For the at-risk group, the results from a 2x2 repeated measures analysis of variance (ANOVA) indicated that there were no significant interactions between time and condition on any of the measures. For the ESL group, there was a statistically significant interaction between the time and condition for the Word Attack, Blending, and Letter-Word Identification subtests indicating that the ABRA intervention was a direct contributor to the improvement of reading skills among ESL students. A discussion focuses on how findings are consistent with and divergent from previous research and offers implications for future research and practice.
Prospects for using integrated atom-photon junctions for quantum information processing

description: We investigate the use of integrated, microfabricated photonic-atomic junctions for quantum information processing applications. The coupling between atoms and light is enhanced by using microscopic optics without the need for cavity enhancement. Qubits that are collectively encoded in hyperfine states of small ensembles of optically trapped atoms, coupled via the Rydberg blockade mechanism, seem a particularly promising implementation. Fast and high-fidelity gate operations, efficient readout, long coherence times and large numbers of qubits are all possible.
