description: Seabridge Gold purchased SnipGold Corp in 2016, which included Iskut Project located in Northwest British Columbia. In collaboration with Tahltan Nation, SnipGold is committed to reclaiming historic legacy and outstanding liabilities at Johnny Mountain Mine (JMM) located within Iskut Project, following approved Closure and Reclamation Plan. To date, SnipGold has invested over C$6 million on reclamation activities at JMM. In last four years, SnipGold has worked in partnership with Tahltan Central Government (TCG), Tahltan Nation Development Corporation (TNDC) and Tahltan Heritage Resources Environmental Assessment Team (THREAT) in implementing a project execution plan and environmental risk assessment. SnipGold and Tahltan Nations have developed a framework for communications, environmental management, employment, contracting, and capacity to ensure Tahltan can continue to exercise their stewardship responsibilities and protect culturally sensitive areas. Since 2016, SnipGold and TCG have worked together to permit and construct an upgraded landfill to hold inert demolition waste from former mill structures, cleaned up historic landfill sites, closed underground vent raises and portals, cleaned and deconstructed fuel tank farm and cleaned out the mill building. Through open and transparent consultation processes, Seabridge Gold has received the support of Tahltan Nation and assurances about working in Tahltan territory and advancing natural resource projects.

description: In Poland, a characteristic feature of live pig production is its dispersion. The purpose of the article is to present the current level of concentration of pig producers and pig population, as well as structural changes that have taken place after Poland’s accession to the European Union. The reference point for the degree of concentration in Poland is the degree of concentration of producers and livestock numbers in countries such as Denmark or Germany. These countries were included in the production and export of pigs and pig meat due to their position. The analysis confirms that despite the progress in concentration, both the structure of producers and the population are still fragmented. In 2018, the Ministry of Agriculture and Rural Development took the initiative to create an electronic sales platform under the name “Food Platform”. One of the goals of its establishment is to strengthen the position of farmers, who are the weakest link in the supply chain. The point is that trading on the Food Platform would bring benefits not only to large companies, but also to small entities that face difficulties to operating independently on the market. One of the products recommended for trade on the Food Platform is red meat (pork and beef) and products from this meat (Szczepaniak, Ambroziak and Drożdż, 2019). Although trade in pork half-carcases is foreseen further (wheat is to be the pilot product) and in addition will be based on transactions between slaughterhouses and processing plants, the fragmentation of production in question will have an impact on this turnover. The turnover on the platform, in turn, may affect the position of farmers. The trade may require joint (group) action of producers, and perhaps also the proper organization of the trade on the part of the platform.

Relationships as Regulatory Systems

subject: Stress (Psychology)--Social aspects

description: Interpersonal relationships are among the most important contributors to health and well-being. This dissertation investigates how and why relationships confer such benefits and proposes that relationships function as dynamic regulatory systems that enable people to cope effectively with challenging situations and pursue important goals. Across five Chapters, this work reveals the role of relationships in scaffolding effective individual self-regulation, dyadic coregulation (how partners dynamically modulate each other’s responses and regulate as a unit), and developmental regulation (adaptation to age-related challenges across the lifespan), particularly in the context of social support interactions. Chapter 1 introduces past research on the importance of social relationships, summarizes the rationale for focusing on social support interactions as a key context in which interpersonal regulation occurs, and presents an overview of the research and methods discussed in this dissertation. Chapter 2 investigates the role of social support in promoting effective self-regulation by conceptualizing, validating, and testing a new theoretical construct, Regulatory Effectiveness of Social Support (RES). RES proposes that recipients benefit from social support to the extent that it addresses their motivations to understand and manage their situation. In eight studies and a meta-analysis, this chapter reveals that receiving social support higher on RES predicts downstream outcomes that are important for effective self-regulation. Chapter 3 examines how social support interactions give rise to dyadic coregulation—dynamic coupling of partners’ physiological states. Results from this chapter demonstrate that social support interactions may be a context in which such coregulation is especially likely to occur, in order to help partners return to an equilibrium of responding, and underscore the importance of considering how dyads regulate as a single, interdependent unit. Chapter 4 presents preliminary evidence for how coregulation among older couples might influence developmental regulation. This chapter shows how between-dyad differences in coregulation processes in turn predict individual self-regulation processes in the face of a stressor. Chapter 5 synthesizes findings across chapters and highlights new avenues for future research. Overall, these findings suggests important self- and coregulatory implications of social support interactions, which may be a crucial mechanism through which interpersonal relationships influence health and well-being over time.
Gravitational waves from pulsating stars: Evolving the perturbation equations for a relativistic star

description: We consider the perturbations of a relativistic star as an initial-value problem. Having discussed the formulation of the problem (the perturbation equations and the appropriate boundary conditions at the centre and the surface of the star) in detail we evolve the equations numerically from several different sets of initial data. In all the considered cases we find that the resulting gravitational waves carry the signature of several of the star's pulsation modes. Typically, the fluid $f$-mode, the first two $p$-modes and the slowest damped gravitational $w$-mode are present in the signal. This indicates that the pulsation modes may be an interesting source for detectable gravitational waves from colliding neutron stars or supernovae. We also survey the literature and find several indications of mode presence in numerical simulations of rotating core collapse and coalescing neutron stars. If such mode-signals can be detected by future gravitational-wave antennae one can hope to infer detailed information about neutron stars. Since a perturbation evolution should adequately describe the late time behaviour of a dynamically excited neutron star, the present work can also be used as a bench-mark test for future fully nonlinear simulations.

description: Chapter one of this thesis examines how tying social insurance to marriage influences matching and marital decisions in the context of Sweden, and draws implications for when it is optimal to separate social insurance from marriage in modern societies. Chapter two analyzes firms' communication strategies in a market where consumers face attention constraints, and discusses regulation that can protect consumers from exploitation. Chapter three studies communication and coercion in the presence of an altruistic relationship, and offers a benevolent rationale for constraining liberty to protect individuals from self-harm, for example through safety mandates.
Large-scale structures in high Reynolds number rotating Waleffe flow

description: We perform direct numerical simulations of rotating turbulent Waleffe flow, the flow between two parallel plates with a sinusoidal streamwise shear driving force, to study the formation of large-scale structures and the mechanisms for momentum transport. We simulate different cyclonic and anti-cyclonic rotations in the range of dimensionless rotation numbers (inverse Rossby numbers) $R_Ω$ $\in$ $[-0.16, 2.21]$, and fix the Reynolds number to $Re=3.16\times 10^3$, large enough such that the shear transport is almost entirely due to Reynolds stresses and viscous transport is negligible. We find an optimum rotation in anti-cyclonic regime at $R_Ω=0.63$, where a given streamwise momentum transport in the wall-normal direction is achieved with minimum mean energy of the streamwise flow. We link this optimal transport to the strength of large scale structures, as was done in plane Couette by Brauckmann \& Eckhardt (J. Fluid Mech., 815, 2017). Furthermore, we explore the large-scale structures and their behaviour under spanwise rotation, and find disorganized large structures at $R_Ω=0$ but highly organized structures in the anti-cyclonic regime, similar to the rolls in rotating plane Couette and turbulent Taylor Couette flow. We compare the large scale structures of plane Couette flow and Waleffe flow, and observe that the streamwise vorticity is localized inside the cores of the rolls. We show that the rolls take energy from the mean flow at long time-scales, and relate these structures to eigenvalues of the streamfunction.

description: Inequivalent standard-like observable sector embeddings in $Z_3$ orbifolds with two discrete Wilson lines, as determined by Casas, Mondragon and Muñoz, are completed by examining all possible ways of embedding the hidden sector. The hidden sector embeddings are relevant to twisted matter in nontrivial representations of the Standard Model and to scenarios where supersymmetry breaking is generated in a hidden sector. We find a set of 175 models which have a hidden sector gauge group which is viable for dynamical supersymmetry breaking. Only four different hidden sector gauge groups are possible in these models.

The C–C bond formation between 3-bromo-9H-pyrido[2.3-b]indole-6-sulfonamide and various boronic acids was achieved with more accessible palladium pre-catalyst, Pd-PEPPSI-IPr via Suzuki coupling under microwave condition in a short reaction time with excellent yields.

Relationship of Family - Non-Family Support to the Academic Performance of Urban of Black Disadvantaged College Students

Year: 1982
Subjects: Social service

description: The purpose of this research was to study the relationship between the levels of support from family and non-family members to the academic performance of urban black disadvantaged college students. The research was designed to answer the question of whether students who expected and received high family and/or non-family support would do better academically than those who expected high support but received low support. The conceptual framework on which the study was based was of "the family as a social system," as formulated by Biddle and Thomas.

Data were collected from 44 students at a four-year urban commuter college located in New York City. These students were first-semester freshmen. Some were in an educational opportunity program which limited its eligibility criteria to persons with high school averages below 80 and family incomes at or below the poverty level. The other portion of the sample group met all of the criteria listed, but was not in the educational opportunity program.

The students were administered a survey form at two times during the Spring 1980 semester. The instruments were designed by the researcher to elicit their perception of expectations of support and actual receiving of support from family and/or non-family members in the emotional, social, financial and informational categories. These categories continuously came up during counseling sessions with students.

A Kruskal-Wallis One-Way Analysis of Variance was performed to determine if there was a significant relationship between the degree of supportiveness from family and non-family members and the academic achievement of urban black disadvantaged college students. The results of the tests did not support the research hypothesis. However, there was definite relationship between support expected and support received.

The major implication of the study is that there may be other more important factors which have an influence on urban disadvantaged students' academic performance.

The implication for social workers in higher education is that as counselors they must be concerned with students and the promotion of policies that have overall social policy implications which will allow the higher education arenas to meet the range of students' needs with understanding and sensitivity.
Superlattice Patterns in Surface Waves

description: We report novel superlattice wave patterns at the interface of a fluid layer driven vertically. These patterns are described most naturally in terms of two interacting hexagonal sublattices. Two frequency forcing at very large aspect ratio is utilized in this work. A superlattice pattern ("superlattice-I") consisting of two hexagonal lattices oriented at a relative angle of 22^o is obtained with a 6:7 ratio of forcing frequencies. Several theoretical approaches that may be useful in understanding this pattern have been proposed. In another example, the waves are fully described by two superimposed hexagonal lattices with a wavelength ratio of sqrt(3), oriented at a relative angle of 30^o. The time dependence of this "superlattice-II" wave pattern is unusual. The instantaneous patterns reveal a time-periodic stripe modulation that breaks the 6-fold symmetry at any instant, but the stripes are absent in the time average. The instantaneous patterns are not simply amplitude modulations of the primary standing wave. A transition from the superlattice-II state to a 12-fold quasi-crystalline pattern is observed by changing the relative phase of the two forcing frequencies. Phase diagrams of the observed patterns (including superlattices, quasicrystalline patterns, ordinary hexagons, and squares) are obtained as a function of the amplitudes and relative phases of the driving accelerations.

description: I study the experience of imprisonment and reentry into society through the perspectives of formerly incarcerated women. My central focus is on how women's relationships help them cope with the hardships of imprisonment and reentry. Whether it is a spiritual relationship with God, a life-saving bond with a fellow inmate, or a deep tie to a family member outside of the walls of prison, relationships for incarcerated women and women reentering society are an important part of their narratives. I conducted formal interviews with eleven women who have spent time in jails and prisons and now live in New York City. I went to Rikers Island, the city's main jail complex, and interviewed five women in jail and observed a holiday event in the women's unit. I also did fieldwork with three nonprofit groups that work with women leaving prison. In the body of this thesis, I examine the negative relationships women face prior to their incarceration often tied to drug addictions and domestic violence. I study power dynamics behind bars and women's relationships with prison guards. I look at how women cope by leaning on each other and forming families behind bars. Separation from children and parents on the other side is a significant strain that I also scrutinize. In addition, I examine the ways in which some women use relationships with God and other modes of spirituality to overcome adversities of incarceration. Finally, I study the difficult process of reentry and the barriers women face as they work to turn their lives around and form positive relationships after prison. Through these studies, I question whether the prison system really helps rehabilitate these women and whether the Department of Corrections does enough to prepare women for life after imprisonment.

Arsenic waste management : Kinetics of arsenic release from orpiment
Creators: name: Mirazimi, M.
name: Liu, Wenying
Publisher: name: The University of British Columbia
Year: 2021

description: Preventing arsenic release from mine waste materials, i.e., source control, is the preferable option for controlling arsenic discharge to the environment. Designing effective source control requires comprehensive knowledge on the leaching behavior of arsenic from its bearing minerals. To determine the release kinetics of arsenic, we carried out leaching experiments using crystalline arsenic trisulfide known as orpiment as one model arsenic sulfide mineral. The effect of pH, the dissolved oxygen concentration, and temperature on the release rate of arsenic was investigated using a fully controlled batch reactor system. In general, the arsenic release rate increased with pH, the dissolved oxygen concentration, and temperature. A kinetic equation was derived from the leaching data to describe the release rate as a function of the three leaching parameters. The kinetic equation derived serves as a useful tool for pinpointing the key factors that can be manipulated to prevent arsenic release from mine waste materials.

description: Amyloid fibrils are formed when soluble proteins misfold into highly ordered insoluble fibrillar aggregates and affect various organs and tissues. The deposition of amyloid fibrils is the main hallmark of a group of disorders, called amyloidoses. Curiously, fibril deposition has been also recorded as a complication in a number of other pathological conditions, including well-known neurodegenerative or endocrine diseases. To date, amyloidoses are roughly classified, owing to their tremendous heterogeneity. In this work, we introduce AmyCo, a freely available collection of amyloidoses and clinical disorders related to amyloid deposition. AmyCo classifies 75 diseases associated with amyloid deposition into two distinct categories, namely 1) amyloidosis and 2) clinical conditions associated with amyloidosis. Each database entry is annotated with the major protein component (causative protein), other components of amyloid deposits and affected tissues or organs. Database entries are also supplemented with appropriate detailed annotation and are referenced to ICD-10, MeSH, OMIM, PubMed, AmyPro and UniProtKB databases. To our knowledge, AmyCo is the first attempt towards the creation of a complete and an up-to-date repository, containing information about amyloidoses and diseases related to amyloid deposition. The AmyCo web interface is available at http://bioinformatics.biol.uoa.gr/amyco.

description: In this paper we study several issues related to the generation of superpotential induced by background Ramond-Ramond fluxes in compactification of Type IIA string theory on Calabi-Yau four-folds. Identifying BPS solitons with D-branes wrapped over calibrated submanifolds in a Calabi-Yau space, we propose a general formula for the superpotential and justify it comparing the supersymmetry conditions in D=2 and D=10 supergravity theories. We also suggest a geometric interpretation to the supersymmetric index in the two-dimensional effective theory in terms of topological invariants of the Calabi-Yau four-fold, and estimate the asymptotic growth of these invariants from BTZ black hole entropy. Finally, we explicitly construct new supersymmetric vacua for Type IIA string theory compactification on a Calabi-Yau four-fold with Ramond-Ramond fluxes.

description: We will compute relative Gromov--Witten invariants of maximal contact order by applying the virtual localization formula to the moduli space of relative stable maps. In particular, we will enumerate genus 0 stable maps to the Hirzebruch surface 𝔽₁ = ℙ(𝒪_ℙ¹ ⊕ 𝒪_ℙ¹ (1)) relative to the divisor 𝐷 = 𝐵 + 𝐹, where 𝐵 is the base and 𝐹 the fiber of the projective bundle. We will provide an explicit description of the connected components of the fixed locus of the moduli space 𝑀̅₀,𝑛 (𝔽₁ ; 𝐷|𝛽 ; 𝜇) using decorated colored graphs and further determine the weight decomposition of their virtual normal bundles. This thesis contains explicit computations for 𝜇 = (3) and 𝛽 = 3𝐹 + 𝐵), and additionally 𝜇 = (4) and 𝛽 ∈ {4𝐹 + 𝐵, 4𝐹 + 2𝐵}. The same methodology however can be applied to any other ramification pattern 𝜇 and curve class 𝛽.

The exact results for the phase diagrams, magnetization, internal energy and specific heat are derived and discussed in detail. The relevant mapping suggests that an isotropic in-plane crystal field (D^x = D^y) leads to the same effects as the hard-axis crystal field (D^z), whereas the in-plane anisotropy (D^x \neq D^y) is responsible also for the randomization of the magnetic ordering (transverse-field like effect).

description: Ultrastable vapor-deposited glasses display uncommon material properties. Most remarkably, upon heating they are believed to melt via a liquid front that originates at the free surface and propagates over a mesoscopic crossover length, before crossing over to bulk melting. We combine swap Monte Carlo with molecular dynamics simulations to prepare and melt isotropic amorphous films of unprecedendtly high kinetic stability. We are able to directly observe both bulk and front melting, and the crossover between them. We measure the front velocity over a broad range of conditions, and a crossover length scale that grows to nearly $400$ particle diameters in the regime accessible to simulations. Our results disentangle the relative roles of kinetic stability and vapor deposition in the physical properties of stable glasses.

By formulating the quantum multiplications on Hilb(T*P¹) computed by Davesh Maulik and Alexei Oblomkov as vertex operators and computing the product expansion, we demonstrate how to get the insertion operator computed by Yaim Cooper and Rahul Pandharipande in the equivariant limits. Brenti proves a non-recursive formula for the Kazhdan-Lusztig polynomials of Coxeter groups by combinatorial methods. In the case of the Weyl group of a split group over a finite field, a geometric interpretation is given by Sophie Morel via weight truncation of perverse sheaves. With suitable modifications of Morel's proof, we generalize the geometric interpretation to the case of finite and affine partial flag varieties. We demonstrate the result with essentially new examples using sl₃ and sl₄..

description: Location: Dewberry Hall The use of the Blackboard "portfolio tool" appears to be an underutilized resource at Mason compared to other settings of higher education. When designed and used properly, this tool has been demonstrated to be a significant resource in promoting a habit of self-directed, life-long learning as it effectively promotes the development of relevant competencies. With an increasing emphasis by programs focusing on competency-based, experiential learning, the "Learning Portfolio" is a type of portfolio that has proven to be an effective tool to organize, measure, and monitor a studentâs learning. It provides an effective method to document the resources that a student has found helpful, their reflections on their learning; their instructors' feedback, and the level of their progress over time.

description: We perform fully relativistic calculations of binary neutron stars in quasi-equilibrium circular orbits. We integrate Einstein's equations together with the relativistic equation of hydrostatic equilibrium to solve the initial value problem for equal-mass binaries of arbitrary separation. We construct sequences of constant rest mass and identify the innermost stable circular orbit and its angular velocity. We find that the quasi-equilibrium maximum allowed mass of a neutron star in a close binary is slightly larger than in isolation.

Relationships between Conceptual Knowledge and Reasoning about Systems: Implications for Fostering Systems Thinking in Secondary Science
Creators: Lyons, Cheryl
Publisher: name: Columbia University
Year: 2014
Subjects: Science--Study and teaching

description: Reasoning about systems is necessary for understanding many modern issues that face society and is important for future scientists and all citizens.  Systems thinking may allow students to make connections and identify common themes between seemingly different situations and phenomena, and is relevant to the focus on cross-cutting concepts in science emphasized in the Framework for K-12 Science Education Standards (NRC, 2011) and Next Generation Science Standards (Achieve, 2013).
      At the same time, there is emerging empirical and theoretical support in science education for fostering the development of science reasoning alongside content understanding, as opposed to the perspective that reasoning occurs after a certain threshold of content mastery has been achieved.  However, existing research on systems thinking has treated this reasoning as a set of universal skills and neglected the role of content, or has conceptualized a progression in which content mastery precedes systems reasoning without consideration of rudimentary forms of reasoning.
      This study focused on describing individual variations in the ways that 8th and 9th grade students reason about changes in a system over time to identify characteristics of systems and pre-systems thinking and to investigate the relationship between this reasoning and the students' application of content.  This study found a generally linear relationship between content and reasoning, with interesting deviations from this trend among students who demonstrated at least a moderate level of content understanding but had not yet achieved mastery.  Four profiles of this relationship emerged which warrant different instructional support.

      Implications are presented for science educators and developers of curricula and assessments.  This includes recommendations for learning objectives, the design of written curriculum materials, and the development of assessments that aim to promote and measure reasoning about systems in science.

description: A measurement of jet substructure variables is presented using data collected in 2016 by the ATLAS experiment at the LHC with proton-proton collisions at $\sqrt{s}=13$ TeV. Large-radius jets groomed with the trimming and soft-drop algorithms are studied. Dedicated event selections are used to study jets produced by light quarks or gluons, and hadronically decaying top quarks and $W$ bosons. The variables measured are sensitive to pronged substructure, and therefore are typically used for tagging jets from boosted massive particles. These include the energy correlation functions and the $N$-subjettiness variables. The number of subjets and the Les Houches angularity are also considered. The distributions of the substructure variables, corrected for detector effects, are compared to the predictions of various Monte Carlo event generators. They are also compared between the large-radius jets originating from light quarks or gluons, and hadronically decaying top quarks and $W$ bosons.

Misconception-Based Learning To Cement Learning

Year: 2019

description: Location: JC Room G Every class has purpose but CLIM 102, Introduction to Global Climate Change Science, in particular because it serves to combat rife misinformation and misconceptions concerning climate change and provide America, and the world, with climate literate citizens. CLIM 102 is a 100-level Mason CORE class typically attended by students from a range of backgrounds, including non-science majors, interested in understanding global climate change, climate modeling, and meeting their natural science lab requirements. In order to cement the students understanding of the physical processes taught to them throughout the semester, we have introduced a climate change myth-busting theme and the culmination of the class with group myth-busting presentations. Students need to use the physical concepts they have been taught to effectively debunk a given climate change myth afflicting societal discourse. This activity is a misconception-based learning activity, an educational approach that teaches scientific concepts through the refutation of scientific misconceptions. This teaching approach has been tested across a range of disciplines and is regarded as one of the most powerful methods of teaching science, resulting in stronger student engagement, longer-lasting learning gains, and increased critical thinking skills. We will present this CLIM 102 myth-busting approach as a template that those from other disciplines could adapt within their classes. To further investigate the effectiveness of this approach we have begun evaluating it this semester (Spring 2019) with an IRB approved research study led by Dr. Cook. Our research will enable us to add to the body of knowledge on misconception-based learning, as well as explore different ways of introducing students to misconceptions. Our plan is to yield further theoretical insights, raise awareness of this approach in the education community, and develop best-practices recommendations. Participants will be able to use the example of its application to a climate change class as a template/starting point/inspiration for developing a similar activity in their own science class.

description: We present a new method for the computation of Lyapunov exponents utilizing representations of orthogonal matrices applied to decompositions of M or MM_trans where M is the tangent map. This method uses a minimal set of variables, does not require renormalization or reorthogonalization, can be used to efficiently compute partial Lyapunov spectra, and does not break down when the Lyapunov spectrum is degenerate.

Launching Graduate Student Writing Groups: Developing A Context-Specific Plan
Creators: name: Bychkovska, Tetyana
name: Lawrence, Susan
Publisher: name: Innovations in Teaching & Learning Conference Proceedings
Year: 2019

description: Location: Dewberry Hall Advanced academic writing can be a challenging, laborious, and lonely activity, especially for graduate students who are still learning the norms of their academic communities, but at the same time are expected to write skillfully and extensively in their programs. Lack of confidence and productivity in writing may play a role in extending time to degree or hindering degree completion (Council of Graduate Schools, 2007). One source for supporting graduate student writers outside of the classroom is writing groups. Motivated by theories of situated learning (Lave & Wenger, 1991) and peer collaboration (Ferris & Hedgecock, 2005; Liu & Hansen, 2002), writing groups provide opportunities for discussing and practicing disciplinary conventions, providing and receiving productive feedback, and engaging in informal mentoring (Simpson, 2019). In addition to professional development opportunities, groups can also improve students’ motivation, help them deal with procrastination, and provide psychological peer support (Hixson et al., 2016; Starke-Meyerring, 2014). These advantages in turn can lead to a greater academic success and the sense of belonging in an academic community. While graduate writing groups have been extensively sponsored by writing centers across the country, including Mason’s Writing Center, student-led writing groups also provide a strong model for enhancing productivity, developing professional skills, and supporting degree completion. Faculty advisors can be instrumental, however, in initiating and launching such groups among their students and advisees (Hixson et al., 2016). The purpose of this poster presentation is to provide faculty, including advisors and program directors, with resources for establishing writing groups among their students and advisees. After introducing different types of groups, including accountability, feedback, and write-together groups, we will discuss the stages of initiating a writing group. These stages include 1) deciding on the format most suitable, given student priorities; 2) planning logistics (e.g., time, space, basic rules) and determining the role that the faculty will play initially; and 3) determining how to position students to take the lead as they move forward. Each stage will include a set of heuristic questions for the faculty to consider in order to create a specific plan for establishing groups in their contexts. While this poster presentation presumes an audience of graduate advisors, graduate writers themselves, as well as faculty who oversee undergraduate research projects, may also find this presentation relevant. Participants will be able to select an appropriate model for a writing group, specific to their context, and begin developing a plan for launching and sustaining such a group.
