description: Introduction: Despite legal protections for young workers in Canada, youth aged 15–24 are at high risk of traumatic occupational injury. While many injury prevention initiatives targeting young workers exist, the challenge faced by youth advocates and employers is deciding what aspect(s) of prevention will be the most effective focus for their efforts. A review of the academic and grey literatures was undertaken to compile the metrics—both the indicators being evaluated and the methods of measurement—commonly used to assess injury prevention programs for young workers. Metrics are standards of measurement through which efficiency, performance, progress, or quality of a plan, process, or product can be assessed. Methods: A PICO (population, intervention, comparison, outcome) framework was used to develop search terms. Medline, PubMed, OVID, EMBASE, CCOHS, PsychINFO, CINAHL, NIOSHTIC, Google Scholar and the grey literature were searched for articles in English, published between 1975-2015. Two independent reviewers screened the resulting list and categorized the metrics in three domains of injury prevention: Education, Environment and Enforcement. Results: Of 174 acquired articles meeting the inclusion criteria, 21 both described and assessed an intervention. Half were educational in nature (N=11). Commonly assessed metrics included: knowledge, perceptions, self-reported behaviours or intentions, hazardous exposures, injury claims, and injury counts. One study outlined a method for developing metrics to predict injury rates. Conclusion: Metrics specific to the evaluation of young worker injury prevention programs are needed, as current metrics are insufficient to predict reduced injuries following program implementation. One study, which the review brought to light, could be an appropriate model for future research to develop valid leading metrics specific to young workers, and then apply these metrics to injury prevention programs for youth.

description: We investigate experimentally the statistical properties of a wind-generated wave field and the spontaneous formation of rogue waves in an annular flume. Unlike many experiments on rogue waves where waves are mechanically generated, here the wave field is forced naturally by wind as it is in the ocean. What is unique about the present experiment is that the annular geometry of the tank makes waves propagating circularly in an unlimited-fetch condition. Within this peculiar framework, we discuss the temporal evolution of the statistical properties of the surface elevation. We show that rogue waves and heavy-tail statistics may develop naturally during the growth of the waves just before the wave height reaches a stationary condition. Our results shed new light on the formation of rogue waves in a natural environment.

A study of the Clausius equation of state.

Subjects: subject: Engineering, Chemical.

description: The purpose of this work is to present an approach and its limitations as applied to the Clausius equation of state to calculate the volume and the heat of mixing. The investigation was begun to continue the research into volume and heat of mixing, specifically through an evaluation of the latest modification of the Clausius equation of state, simply by considering the three parameters as temperature dependent. The results of the evaluation indicate that the proposed approach is good for predicting volumes of mixing but not entirely adequate for predicting heats of mixing. Thus, an alternative approach has been investigated by considering two of the parameters as temperature dependent which appears more adequate and versatile for predicting these thermodynamic properties.
Wake of slot jet studies.

Subjects: subject: Engineering, Chemical.

description: Flow patterns developed by the inclined slot air jets, injected in a main air stream flowing at different velocities from 132.5--208 feet per second in a four0inch square duct, were studied from numerous pressure probe readings. Velocity profiles across the width of the duct at various positions were obtained from the readings on a recorder chart, given by the travelling probe. An elliptical shaped zone of air recirculation was indicated from the velocity readings at different points. Several correlations were obtained to preduct the area and the position of the zone of recirculation, when the fluid properties in the jet stream and the main stream are known. From the date obtained in this experiment, the similarity drawn between the jet fluid obstruction and the bluff-body obstruction, seemed to be somewhat questionable.

description: Background: Prior qualitative research on gout has focused primarily on barriers to disease management. Our objective was to use patients’ perspectives to construct an explanatory framework to understand how patients become engaged in the management of their gout. Methods: We recruited a sample of individuals with gout who were participating in a proof-of-concept study of an eHealth-supported collaborative care model for gout involving rheumatology, pharmacy, and dietetics. Semistructured interviews were used. We analyzed transcripts using principles of constructivist grounded theory involving initial coding, focused coding and categorizing, and theoretical coding. Results: Twelve participants with gout (ten males, two females; mean age, 66.5 ± 13.3 years) were interviewed. The analysis resulted in the construction of three themes as well as a framework describing the dynamically linked themes on (1) processing the diagnosis and management of gout, (2) supporting management of gout, and (3) interfering with management of gout. In this framework, patients with gout transition between each theme in the process of becoming engaged in the management of their gout and may represent potential opportunities for healthcare intervention. Conclusions: Findings derived from this study show that becoming engaged in gout management is a dynamic process whereby patients with gout experience factors that interfere with gout management, process their disease and its management, and develop the practical and perceptual skills necessary to manage their gout. By understanding this process, healthcare providers can identify points to adapt care delivery and thereby improve health outcomes.

description: Background The mammalian target of rapamycin (mTOR) is a regulator of cell proliferation, cell growth and apoptosis working through two distinct complexes: mTORC1 and mTORC2. Although much is known about the activation and inactivation of mTORC1, the processes controlling mTORC2 remain poorly characterized. Experimental and modeling studies have attempted to explain the regulation of mTORC2 but have yielded several conflicting hypotheses. More specifically, the Phosphoinositide 3-kinase (PI3K) pathway was shown to be involved in this process, but the identity of the kinase interacting with and regulating mTORC2 remains to be determined (Cybulski and Hall, Trends Biochem Sci 34:620-7, 2009). Method We performed a literature search and identified 5 published hypotheses describing mTORC2 regulation. Based on these hypotheses, we built logical models, not only for each single hypothesis but also for all combinations and possible mechanisms among them. Based on data provided by the original studies, a systematic analysis of all models was performed. Results We were able to find models that account for experimental observations from every original study, but do not require all 5 hypotheses to be implemented. Surprisingly, all hypotheses were in agreement with all tested data gathered from the different studies and PI3K was identified as an essential regulator of mTORC2. Conclusion The results and additional data suggest that more than one regulator is necessary to explain the behavior of mTORC2. Finally, this study proposes a new experiment to validate mTORC1 as second essential regulator.

description: Motor neurons in the spinal cord are found grouped in nuclear structures termed pools, whose position is precisely orchestrated during development. Despite the emerging role of pool organization in the assembly of spinal circuits, little is known about the morphogenetic programs underlying the patterning of motor neuron subtypes. We applied three-dimensional analysis of motor neuron position to reveal the roles and contributions of cell adhesive function by inactivating N-cadherin, catenin, and afadin signaling. Our findings reveal that nuclear organization of motor neurons is dependent on inside-out positioning, orchestrated by N-cadherin, catenin, and afadin activities, controlling cell body layering on the medio-lateral axis. In addition to this lamination-like program, motor neurons undergo a secondary, independent phase of organization. This process results in segregation of motor neurons along the dorso-ventral axis of the spinal cord, does not require N-cadherin or afadin activity, and can proceed even when medio-lateral positioning is perturbed.

description: L’objectif de ce travail est d’étudier l’impact des inégalités sociales sur la croissance économique au Maroc durant la période 1990-2021 en utilisant une démarche économétrique basée sur le modèle ARDL. Le phénomène des inégalités touche plusieurs pays du monde, et selon les rapports nationaux et internationaux le Maroc est affecté par ce phénomène qui exerce des influences sur l’économie est surtout sur la croissance économique du pays.

Les résultats de l'analyse ARDL indiquent une relation significative et négative entre les inégalités sociales et la croissance économique au Maroc. Une augmentation des inégalités sociales est associée à une réduction de la croissance économique à long terme. Cela suggère que les inégalités sociales peuvent agir comme un frein à la croissance économique du pays.

description: Genome-wide association studies identified a 5' APOC1 single nucleotide polymorphism (SNP), rs4420638 (minor allele frequency (MAF)=0.18) at 19q13.2, with a CAD risk odds ratio (OR) of 1.17 (1.08-1.28) in linkage disequilibrium with apoE4 risk SNP rs429358 (r 2=0.70; OR=1.06 (0.99-1.13), MAF=0.15). Differing OR and MAF led to the hypothesis that rs4420638 risk is partially independent to rs429358. Additional SNPs not in HapMap were genotyped by sequencing, however no strong linkage existed. Genotypically associated traits include serum apoE, as determined by ELISA (rs4420638 AA: 25.5+/-4.8; AB: 44.8+/-3.1; BB: 69.9+/-3.7ug/ml; p=7.27E-07, rs429358 AA: 14.8+/-3.4; AB: 40.1+/-3.1; BB: 67.0+/-3.4ug/ml; p=1.73E-08) and LDL (linear regression rs4420638 p=0.0007; rs429358 p=0.003) but not apoC1. Haplotype analysis indicated that rs429358 risk allele confers a greater CAD risk than rs4420638: rs4420638 risk allele alone is 6% in cases and 4% in controls; rs429358 risk allele is 3% in cases and 0.3% in controls. Likelihood ratio test confirms this conclusion.

description: Understanding and interpreting classification decisions of automated image classification systems is of high value in many applications, as it allows to verify the reasoning of the system and provides additional information to the human expert. Although machine learning methods are solving very successfully a plethora of tasks, they have in most cases the disadvantage of acting as a black box, not providing any information about what made them arrive at a particular decision. This work proposes a general solution to the problem of understanding classification decisions by pixel-wise decomposition of nonlinear classifiers. We introduce a methodology that allows to visualize the contributions of single pixels to predictions for kernel-based classifiers over Bag of Words features and for multilayered neural networks. These pixel contributions can be visualized as heatmaps and are provided to a human expert who can intuitively not only verify the validity of the classification decision, but also focus further analysis on regions of potential interest. We evaluate our method for classifiers trained on PASCAL VOC 2009 images, synthetic image data containing geometric shapes, the MNIST handwritten digits data set and for the pre-trained ImageNet model available as part of the Caffe open source package.
Theoretical study of polymers: Flow-induced deformation in nanochannels and reptation dynamics in heterogeneous gels

description: In 1992, B. Smith, L. Finzi and C. Bustamante were the first to directly observe the behaviour of a single DNA molecule with the help of video fluorescence microscopy. Their results greatly improved our understanding of the static and dynamic properties of a single isolated chain which represents the foundation of polymer physics. A series of experimental results and theoretical models followed the work of Smith et al. Current theoretical approaches to study polymers involve many techniques: thermodynamic analysis, field theory, scaling, renormalization group theory and computer simulations. In Chapter 2, we present a Molecular Dynamics study of the effect of strong lateral confinement on the properties of a tethered polymer pulled at constant velocity. Our results are compared with recent theoretical predictions and experimental results. One can also ask questions about the behaviour of dilute polymer solutions, or even concentrated solutions such as melts or gels, where the interactions among the polymers are important. For instance, gel electrophoresis (GE) is one of the most common analytical tools used in biology. Since the introduction of GE in 1937, molecular biology has grown substantially. Indeed, GE has shown to be an excellent separation method for DNA molecules since in free solution, the electrophoretic mobility of a DNA molecule is independent of its size. Because of that, most of the theoretical developments in the field have been aimed at improving DNA electrophoretic separation tools. In 1993, Zimm and Lumpkin proposed a new reptation model to explain gel electrophoresis of polyelectrolytes in irregular matrices. Following this work, we propose in Chapter 3 a more detailed model of this problem where the well-known memory effects of the standard reptation theory are taken into account. Our results are in qualitative agreement with available experimental results and disagree with those of Zimm and Lumpkin. In Chapter 4, we examine the reptation of a polymer in a static environment with quenched random energies that are correlated over a finite length scale lambda based on the algorithm detailed in Chapter 3. The results obtained differ from our previous model (Chapter 3) and are compared with those of Zimm and Lumpkin.

description: Dans Therese Raquin (1867) et La Bete humaine (1890), Zola met en scene des personnages qui, en principe, tuent sans remords. Le lien entre ces deux romans naturalistes est bien documente, grace aux commentaires de Zola dans "l'Ebauche" de La Bete humaine. Exemples des "romans noirs" zoliens, Therese Raquin et La Bete humaine racontent des histoires de meurtre et d'adultee. Dans les deux cas, les meurtres sont inevitables, Therese Raquin raconte une fatalite physiologique et La Bete humaine, une fatalite genetique. Pour representer le reel dans ses romans, Zola s'inspire des faits tires de l'actualite, mais, aussi, des discours sociaux, philosophiques et surtout scientifiques de son epoque. Afin de repeer ces differents discours du Second Empire et de la Troisieme Republique, nous aurons recours aux travaux de Marc Angenot 1889 Un Etat du discours social et Henri Mitterand, "l'Introduction" a Therese Raquin pour repondre a la question: est-ce que les criminels de Therese Raquin et La Bete humaine sont vraiment des criminels sans remords?

description: Bien que le mouvement en soins palliatifs pédiatriques ait pris de l'ampleur en Amérique du Nord, il demeure que l'expérience vécue par les infirmières suivant le décès d'un enfant semble très peu explorée. Une approche phénoménologique a été utilisée dans le but de décrire l'expérience de deuil telle que vécue par des infirmières suivant le décès d'un enfant. Les données ont été recueillies au cours d'entrevues semi-structurées effectuées auprès de six infirmières autorisées travaillant dans un établissement de soins palliatifs pédiatriques. Les enregistrements ont été transcrits verbatim et analysés suivant la méthode de Colaizzi (1978). Trois thèmes majeurs ont émergé soit le rôle de l'infirmière durant l'accompagnement, la réflexion envers son deuil et la reconnaissance de son deuil. Les résultats démontrent que les infirmières comprennent clairement leur rôle et accordent beaucoup d'importance et d'attention aux besoins de la famille et de l'enfant. Elles ont décrit leur deuil comme étant unique et personnel et qui doit être reconnu afin qu'elles puissent le surmonter. Elles soulignent aussi l'importance de s'occuper de soi-même et de s'offrir un soutien entre collègues afin de continuer leur travail en soins palliatifs. Les résultats de cette étude apportent une contribution majeure sur l'expérience de deuil telle que vécue par des infirmières en soins palliatifs pédiatriques et peuvent servir de guide dans la prestation des soins à cette population.
Magneto-tunneling of holes in Si/Si1-xGex/Si double barrier structures.
Creators: name: Low, Robert C. D.
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 1991
Subjects: subject: Physics, Condensed Matter.

description: Resonant and non-resonant tunneling processes in p-type Si/Si$\sb{\rm 1-x}$Ge$\sb{\rm x}$/Si double barrier structures were investigated at cryogenic temperatures in both planar and perpendicular magnetic fields. A differential conductance measurement technique was devised to observe non-resonant tunneling features superimposed on a rapidly increasing current background. An additional resonant feature was observed at high bias voltage and is attributed to tunneling of holes from the two-dimensional heavy hole subband in the emitter to a third quasi-bound state in the quantum well. Experimental evidence for non-resonant tunneling processes is presented for the first time in p-type double barrier structures. Inter-Landau level transitions between the emitter and the quantum well occur either elastically by scattering from impurities or inelastically with the emission of optical phonons. Both processes have been observed in our samples. Data above 4.2 K suggest that tunneling processes also take place from the three-dimensional valence band edge states in the emitter. A novel spectroscopy of the quasi-bound states in the well was performed by measuring the shift in energy of the resonant tunneling features as a function of applied planar magnetic field.
Premature witch hunt? The Amerasia case in context
Creators: name: Girard, Timothy J

Subjects: subject: History, United States.
subject: Law.

description: The Amerasia case concerned the theft of classified U.S. federal government documents by government officials and left-wing critics of U.S. foreign policy. The case did not result in serious criminal penalties and the failure of the prosecution has never been adequately explained. There is some superficial validity to the contention that the case was legally weak to begin with, but it is important to situate the Amerasia case in the context of the debate over the direction of U.S. foreign policy in the transition from World War II to the Cold War. Although conclusions on the subject at this point must remain tentative, there is persuasive evidence that the Truman administration ensured that the U.S. Justice Department did not prosecute the case vigorously because a committed prosecution of the Amerasia case had the potential to compromise or undermine U.S. foreign policy in the early months of the Truman presidency.
Influence of phosphorylation on caspase-3-mediated Akt1 cleavage

description: Caspase-3, an executioner of apoptosis, is negatively regulated by X-linked inhibitor of apoptosis protein (XIAP), a determinant of cisplatin resistance. XIAP down-regulation in ovarian cancer cells or treatment with cisplatin induces caspase-3-mediated AKT cleavage and apoptosis, while XIAP over-expression suppresses this cleavage and increases phospho-AKT content. The identity of the caspase-3 cleavage site(s) in AM and the possible dependence of caspase-3-mediated cleavage on its phosphorylation status are unknown. The objectives of this thesis were to determine the caspase-3 cleavage site(s) in Akt1 and to examine the influence of phosphorylation on Akt1 cleavage in vitro. Our results suggested presence of three non-consensus (EEEE 117, EEMD119, DAKE398) and one consensus (DQDD456) cleavage sites, and posphorylation of Akt1 influenced the pattern of cleavage in a site-specific manner: Whereas cleavage at site "EEEE117" was facilitated by phosphorylation, that at sites "EEMD119 and DAKE398'' were attenuated. The biological significance of these observations requires future investigation.
Social Networks for Social Change: Looking into Morality and Accountability during times of National Crises in the United States
Creators: name: Bresolin, Jenna

Subjects: subject: Web Studies.
subject: Mass Communications.

description: The thesis explores the ways in which Americans on two popular social network sites, Facebook and YouTube, conceptualize the issues of crises, specifically financial, health care, and war, in the name of achieving social change and investigates the two-way flow of communication between the government and its citizens through social network sites. The thesis epistemologically feeds from the works of Thomas Hobbes' (1651) theory of government responsibility to society, William James' (1910) theory on crisis and social change, and Hannah Arendt's (1958) theory on collective action and is further guided by the theoretical frameworks of Jurgen Habermas' (1976; 1989) undistorted communication and public sphere theories and Manuel Castells' (1996; 2007) network and mass self-communication theories. Qualitative content analysis through purposive, quota, and sequential sampling of the comments posted on the White House's social media pages is conducted to gauge citizens' sentiments and conceptualizations. The findings show that Americans desire change through increased citizen participation in both politics and the community in addition to higher standards of government accountability. Social network sites contribute by providing a method to facilitate government two-way communication through an unprecedented level of speed and accessibility, which is imperative for social change to occur in the new digital age. Social media sites are conducive to social change because they allow for near-universal access despite geographic limitations, promote government accountability and transparency, and provide a public sphere-like environment for debate and conversation, all of which allow for the betterment of society and provide the method through which crises can be assuaged.
Unplanned Hospital Readmissions in British Columbia

description: Unplanned hospital readmissions affect 9.1% of Canadian patients and cost more than $1.8 billion per year. Hospital readmission rates are publicly reported in Canada and often interpreted as a marker of health system performance. Regrettably, British Columbia has one of the highest 30-day readmission rates nationwide (9.7%). This should motivate clinicians, hospitals, and health authorities to institute programs that monitor and prevent unplanned hospital readmissions.

description: Dans cette thèse qui se veut être une modeste contribution à la réflexion et à la recherche des voies et moyens pour que l'Église du Cameroun parvienne à l'autonomie financière, nous nous sommes proposé d'étudier les normes canoniques prévues par l'Église pour une administration saine et responsable des biens temporels, en particulier dans la paroisse. D'où le titre la thèse l'administration des biens temporels de la paroisse d'après le Code de droit canonique de 1983: application à l'Église du Cameroun. Dans le premier chapitre, nous resituons cette réalite ecclésiale qu'est la paroisse dans son évolution juridique et présentons brièvement l'administration de ses biens au cours de l'histoire. La paroisse n'a pas toujours été cette structure ecclésiale que nous connaissons aujourd'hui. Sa compréhension et même son organisation ont evolué au cours des siècles. Tout comme sa compréhension juridique, les structures permettant à la paroisse de mener à bien sa mission ont évolué au cours des siècles, notamment en ce qui concerne l'administration des biens temporels. Le deuxième chapitre est une étude de la structure de participation et de coresponsabilité des fidèles dans l'administration des biens de la paroisse. Il s'agit ici du Conseil paroissial pour les affaires économiques, organisme prévu par le nouveau Code pour aider l'administrateur des biens temporels de la paroisse dans sa charge. Comme tous les autres conseils dans l'Église, celui-ci trouve son fondement dans l'ecclésiologie de communion dont la conséquence est la participation et la coopération de tous les baptisés, dans l'échange et le dialogue, à la réalisation de la mission que le Christ a confiée a l'Église. Le troisième chapitre, qui est une étude de l'administration des biens d'Église au Cameroun dans les premières décennies de l'évangélisation dans ce pays, nous permet de découvrir que les difficultés qu'ont connus les premiers missionnaires au Cameroun, furent dans l'administration des biens temporels. Le quatrième chapitre est une présentation de la législation particulière actuelle en matière d'administration des biens dans les paroisses de quelques diocèses du Cameroun. Ce travail de législation particulière reste à parfaire, notamment dans le domaine de l'inculturation et de respect de certaines normes du droit civil.

description: This thesis deals with response compaction techniques of BIST of VLSI circuits which translates into a process of reducing the test response of the circuit under test (CUT) to a signature. Instead of comparing bit by bit the fault free responses to the observed outputs of the CUT as in conventional testing, here the observed signature is compared to the correct one, thereby reducing the storage requirements for the correct CUT responses. The thesis specifically deals with designing efficient space compaction techniques for BIST of VLSI circuits using nonexhaustive test sets. The developed techniques utilize the concepts of Hamming distance, sequence weights (generalized), and failure probabilities with multiplicities of errors at the CUT output in selecting specific gates for merger of a number of outputs streams from the CUT using a generalized mergeability criteria. The criteria are developed under conditions of both stochastic independence and stochastic dependence of line errors. Design algorithms are proposed in the thesis and the methods of implementation were demonstrated with many examples. (Abstract shortened by UMI.)

Monitoring

description: The chapter reviews progress in monitoring and modelling of atmospheric nitrogen (N) deposition at regional and global scales. The Working Group expressed confidence in the inorganic N wet deposition estimates in U.S., eastern Canada, Europe and parts of East Asia. But, long-term wet or dry N deposition information in large parts of Asia, South America, parts of Africa, Australia/Oceania, and oceans and coastal areas is lacking. Presently, robust estimates are only available for inorganic N as existing monitoring generally does not measure the complete suite of N species, impeding the closing of the atmospheric N budget. The most important species not routinely measured are nitrogen dioxide (NO2), ammonia (NH3), organic N and nitric acid (HNO3). Uncertainty is much higher in dry deposition than in wet deposition estimates. Inferential modelling (combining air concentrations with exchange rates) and direct flux measurements are good tools to estimate dry deposition; however, they are not widely applied. There is a lack of appropriate parameterizations for different land uses and compounds for input into inferential models. There is also a lack of direct dry deposition flux measurements to test inferential models and atmospheric model estimates. Quelle: http://link.springer.com

description: Finding massive galaxies that stopped forming stars in the early Universe presents an observational challenge because their rest-frame ultraviolet emission is negligible and they can only be reliably identified by extremely deep near-infrared surveys. These surveys have revealed the presence of massive, quiescent early-type galaxies1, 2, 3, 4, 5, 6 appearing as early as redshift z ≈ 2, an epoch three billion years after the Big Bang. Their age and formation processes have now been explained by an improved generation of galaxy-formation models7, 8, 9, in which they form rapidly at z ≈ 3–4, consistent with the typical masses and ages derived from their observations. Deeper surveys have reported evidence for populations of massive, quiescent galaxies at even higher redshifts and earlier times, using coarsely sampled photometry. However, these early, massive, quiescent galaxies are not predicted by the latest generation of theoretical models7, 8, 9, 10. Here we report the spectroscopic confirmation of one such galaxy at redshift z = 3.717, with a stellar mass of 1.7 × 1011 solar masses. We derive its age to be nearly half the age of the Universe at this redshift and the absorption line spectrum shows no current star formation. These observations demonstrate that the galaxy must have formed the majority of its stars quickly, within the first billion years of cosmic history in a short, extreme starburst. This ancestral starburst appears similar to those being found by submillimetre-wavelength surveys11, 12, 13, 14. The early formation of such massive systems implies that our picture of early galaxy assembly requires substantial revision.

description: In this paper, we present a two-phase microfluidic system capable of incubating and quantifying microbead-based agglutination assays. The microfluidic system is based on a simple fabrication solution, which requires only laboratory tubing filled with carrier oil, driven by negative pressure using a syringe pump. We provide a user-friendly interface, in which a pipette is used to insert single droplets of a 1.25-µL volume into a system that is continuously running and therefore works entirely on demand without the need for stopping, resetting or washing the system. These assays are incubated by highly efficient passive mixing with a sample-to-answer time of 2.5 min, a 5–10-fold improvement over traditional agglutination assays. We study system parameters such as channel length, incubation time and flow speed to select optimal assay conditions, using the streptavidin-biotin interaction as a model analyte quantified using optical image processing. We then investigate the effect of changing the concentration of both analyte and microbead concentrations, with a minimum detection limit of 100 ng/mL. The system can be both low- and high-throughput, depending on the rate at which assays are inserted. In our experiments, we were able to easily produce throughputs of 360 assays per hour by simple manual pipetting, which could be increased even further by automation and parallelization. Agglutination assays are a versatile tool, capable of detecting an ever-growing catalog of infectious diseases, proteins and metabolites. A system such as this one is a step towards being able to produce high-throughput microfluidic diagnostic solutions with widespread adoption. The development of analytical techniques in the microfluidic format, such as the one presented in this work, is an important step in being able to continuously monitor the performance and microfluidic outputs of organ-on-chip devices.
The Effects of Flipped Classroom Instruction on Indonesian EFL Students' Speaking Ability in One Higher Learning Institution
Creators: name: Baskara, Risang
Publisher: name: Swinburne
Year: 2024

description: This study explores how a new teaching method called "flipped learning" can help Indonesian college students improve their English speaking skills. Flipped learning involves students watching lessons online before class and engaging in interactive activities during class time. Researchers used a mix of surveys, tests, and interviews with 40 students to see if this approach improved their speaking abilities. Results showed that students' speaking performance improved, and they enjoyed the personalized and engaging nature of the flipped learning method. The study also created a new teaching framework based on this approach that could be useful in other language-learning settings.

description: The present paper demonstrates how Structural Equation Modelling (SEM) can be used to formulate a test of the difference in means between groups on a number of dependent variables. A Monte Carlo study compared the Type I error rates of the Likelihood Ratio (LR) Chi-square ($\chi\sp2$) statistic (SEM test criterion) and Hotelling's two-sample T$\sp2$ statistic (MANOVA test criterion) in detecting differences in means between two independent samples. Seventy-two conditions pertaining to average sample size ((n$\sb1$ + n$\sb2$)/2), extent of inequality of sample sizes (n$\sb1$:n$\sb2$), number of variables (p), and degree of inequality of variance-covariance matrices ($\Sigma\sb1$:$\Sigma\sb2$) were modelled. Empirical sampling distributions of the LR $\chi\sp2$ statistic and Hotelling's T$\sp2$ statistic consisted fo 2000 samples drawn from multivariate normal parent populations. The actual proportion of values that exceeded the nominal levels are presented. The results indicated that, in terms of maintaining Type I error rates that were close to the nominal levels, the LR $\chi\sp2$ statistic and Hotelling's T$\sp2$ statistic were comparable when $\Sigma\sb1$ = $\Sigma\sb2$ and (n$\sb1$ + n$\sb2$)/2:p was relatively large (i.e., 30:1). However, when $\Sigma\sb1$ = $\Sigma\sb2$ and (n$\sb1$ + n$\sb2$)/2:p was small (i.e., 10:1) Hotelling's T$\sp2$ statistic was preferred. When $\Sigma\sb{1} \not=\Sigma\sb2$ the LR $\chi\sp2$ statistic provided more appropriate Type I error rates under all of the simulated conditions. The results are related to earlier findings, and implications for the appropriate use of the SEM method of testing for group mean differences are noted.
