The long emancipation ::moving toward black freedom /
No full text"Rinaldo Walcott posits that Black people globally live in the time of emancipation and that emancipation is definitely not freedom, showing that wherever Black people have been emancipated from slavery and colonization, a potential freedom became thwarted."-
A History of Violence
No full textRinaldo Walcott discusses how the convergence of police violence and COVID-19 on George Floyd’s body encapsulates a history of violence that Black people collectively experience in North America. Walcott unpacks how, in the midst of a pandemic and under stringent restrictions on movement and gathering in groups, George Floyd was murdered publicly for allegedly passing a counterfeit twenty-dollar bill. His murder by police tells a story of the kind of society in which we collectively reside and the necessary changes that need to be made to achieve justice for all
Assemblages Symposium - Leanne Simpson, Rinaldo Walcott and Glen Coulthard
No full textDr. Leanne Simpson and Dr. Rinaldo Walcott discuss Idle No More and Black Lives Matter at the Global Movement Assemblages Symposium with Glen Coulthard as a respondent. The Global Movement Assemblages Symposium was held on October 13-15, 2016 by the Social Justice Research Institute at Brock University
BlackLife : Post-BLM and the Struggle for Freedom
No full text"What does it mean in the era of Black Lives Matter to continue to ignore and deny the violence that is the foundation of the Canadian nation state? BlackLife discloses the ongoing destruction of Black people as enacted not simply by state structures, but beneath them in the foundational modernist ideology that underlies thinking around migration and movement, as Black erasure and death are unveiled as horrifically acceptable throughout western culture. With exactitude and celerity, Idil Abdillahi and Rinaldo Walcott pull from local history, literature, theory, music, and public policy around everything from arts funding, to crime and mental health--presenting a convincing call to challenge pervasive thought on dominant culture's conception of Black personhood. They argue that artists, theorists, activists, and scholars offer us the opportunity to rethink and expose flawed thought, providing us new avenues into potential new lives and a more livable reality of BlackLife." -- Publisher's website

Honour and recognition in the German novel of banditry ca 1800
No full textThis article performs a reading informed by Honneth’s theory of recognition of the two best-known German novels of banditry of the 1790s, Johann Heinrich Zschokke’s Abaellino der große Bandit (1794) and Christian August Vulpius’ Rinaldo Rinaldini (1799) in an effort to understand how popular literature participates in and reflects upon the discourse on honour and recognition around 1800. Its status as popular genre makes the novel of banditry (Räuberroman) a potentially interesting source on shifts in the theory and practice of honour as experienced by ordinary Europeans at the turn of the 19th century. The genre was found to relate to the honour discourse not directly, but in the manner of a heterotopia, simultaneously located outside that discourse and referentially connected to it. Taken in isolation, the novel of banditry is not an informative source on the changing role of honour and new patterns of intersubjective recognition in late 18th century Europe. Seen as part of a particular constellation of textual production and reception, however, the genre sheds light on the aporias of honour experienced by those socially marginal ‘new readers’ intent on exploiting literature in the struggle for enhanced social recognition.Peer reviewe
Albori di Entomologia merceologica e urbana nell'opera del microscopista Filippo Bonanni (1638-1725)
No full textFILIPPO BONANNI (1638-1725)
The Roman Jesuit Filippo Bonanni (1638-1725) is a prominent figure in the European cultural
landscape of the seventeenth and eighteenth centuries. He was a scholar, a man of many interests,
both humanistic and scientific, an eclectic writer; in the history of biological sciences Bonanni
occupies a non-marginal position for his contributions in the malacological and entomological
fields, but he is best known for being, in the wake of his master the Jesuit Athanasius Kircher, a
staunch defender of the theory of spontaneous generation. This certainly damaged his reputation
as a scholar in comparison with more or less contemporary scientists who instead contributed to
refuting this theory with accurate experimental research (among the Italians, in this regard, Redi,
Malpighi, Marsili, Cestoni and Vallisnieri stand out). Bonanni’s observations on insects and other
arthropods, which he carried out above all with the aim of finding arguments in favor of the
generatio aequivoca, are found in his work Observationes circa viventia, quae in rebus non
viventibus reperiuntur. Cum micrographia curiosa sive rerum minutissimarum observationibus,
quae ope microscopii recognitae ad vivum exprimuntur, published in Rome in 1691. Written
observations thus supporting spontaneous generation, but accompanied by numerous valuable
illustrations made with the aid of the microscope which Bonanni, valiant microscopist as well as
a skilled draftsman and engraver, perfected himself, in order to investigate the microcosm of
arthropods beyond the potential of the human eye - apart from the dialectical intent mentioned
above. This is the primary objective of the Micrographia curiosa, the appendix to his work, which
enriches what is presented in the main part of the volume with further findings and tables. A
valuable work, above all related to commodity, urban and stored product entomology, given that
the author finds in the arthropods of the urban and domestic environment the raw material most
at hand as a source for observations and experiences. With surprising precision for the time, in
the Observationes mosquito, sand fly, flea, lice, booklice, coleopteran larvae, moths, other
dipterans and their details, mites, etc. are illustrated. Bonanni is the first descriptor and illustrator
ever of certain insects. Among others, worthy of note is a dermestid larva, very probably of the
genus Anthrenus, with much enlarged detail of the typical hastisetae or spear bristles, and some
figures of pretarsi of Diptera Brachycera. As a microscopist he can be compared to the
Englishman Robert Hooke (1635-1709), almost coeval, who published a Micrographia in London
(1667), from which Bonanni seems to have drawn useful insights
Local scouring at bed sills under steady and unsteady conditions
No full textDesigners are often required to produce safe and economic structures in rivers with erodible beds, which may frequently induce scouring phenomena as they interfere with the natural stream. In CHAPTER 1, an extensive literature is illustrated on scouring by jets at high and low head structures, and predictive formulae are discussed that estimate the equilibrium scour depth of the scour hole, which are most obtained empirically from field and laboratory data. It is also discussed that different stages occur during local scour development. These stages basically include an initial rapid phase of severe scouring, followed by a stabilization phase approaching equilibrium conditions after a long time.
CHAPTER 2 describes the theoretical basis to deal with long-term local scouring at bed sills under clear-water and steady-flow conditions. In gravel bed rivers, bed sills are used to limit bed degradation. Local scouring takes place downstream of each sill in addition to the general erosion pattern, and scour hole dimensions increase with the distance between sills. While overall aggradation can be estimated by using 1D morphological models, local scouring requires a more empirical approach. In fact most scouring phenomena are induced by turbulent jets that diffuse within the scour hole, by resulting in extremely complex flow fields. Many approaches are fully empirical, being based on curve fitting of experimental data that link scour depth to hydraulic quantities and sediment properties. In the most recent attempts, a semi-empirical approach has been followed, based on the identification of appropriate dimensionless groups using dimensional analysis before employing best-fitting procedures. The theoretical derivations proposed, which are based on the assumptions of the Buckingham's ?-theorem, are discussed by showing some further insights on the nature and role of the dimensionless parameters that ensued form dimensional analysis.
CHAPTER 3 presents the results of experimental tests carried out by the author in 2003 about the pattern of local scouring generated at the toe of bed sills. The aim of this study is to evaluate the effect of upstream sediment supply on the scour depth and shape. The experiments simulated conditions of a steady upstream sediment supply which had the same grain size composition as the sediment deposit placed on the bed of the flume. The geometric characteristics of three scour holes developed under conditions of steady-flow discharge and steady upstream sediment supply were measured during 48 different tests. It is shown that the imposed sediment transport does not require the introduction of new dimensionless parameters into existing scour depth and length prediction formulae. The effects of sediment feed are shown to be incorporated in the existing dimensionless parameters. The new data set is used to re-calibrate existing scour depth formula. The influence of jet erosion on scour geometry is also discussed.
Most research efforts have focused on predicting scour depth, which may affect the structure at the free overfall, as opposed to volumetric scour dimensions and sediment yield contribution due to local scour, which may affect downstream morphology and water quality as well as the structure but are much more difficult to measure in an actively eroding plunge pool. In CHAPTER 4, shape and volume of equilibrium local scour holes at bed sills in high-gradient streams are investigated by analyzing steady-flow scour profiles at the equilibrium stage. Geometric properties of the scour profile are analytically discussed and verified on the basis of new data from experimental tests described in CHAPTER 3 and data from literature. A model is presented to organize data analysis into a conceptual frame, which is based on the formal relationships for scour depth and length ensued from dimensional analysis, and on the assumption that scours exhibit definite geometric properties. Results show evidence of a universal geometric affinity of the scour. Geometric similarity is also found to occur, but only in a limited range of physical conditions. Prediction formulae are proposed which link the eroded volume to the geometric, hydraulic and sediment properties. Evidence on the scaling nature of the scour hole shapes have important implications on the prediction of the eroded volume. In turn, a correct evaluation of the eroded volume is necessary for the optimization of the design of the inter-sill distance.
The temporal development of clear-water local scour depth at bed sills in uniform gravel beds is considered in CHAPTER 5. A new experimental program has been carried out by the author, which started at the end of 2006 and was concluded in March 2007 at the Fluid Dynamics Laboratory of The University of Auckland (NZ). Experiments are presented on the development of scour holes under unsteady hydraulic conditions, with the triangular-shaped hydrographs tested being of different durations and different rates of flow variation. Preliminary observations are discussed on the behavior of scour development, which is compared with the scour evolution for the steady-state case. Based on the experimental results and a theoretical framework, a method is given for the definition and prediction of the scouring process under unsteady flows in terms of a dimensionless temporal parameter. A "flash flood" is defined as an event for which the scour doesn't attain its potential magnitude, i.e. the equilibrium value for the peak hydrograph flow rate. It is shown that this flood nature is dependent on both the characteristics of the flood event itself and the characteristics of the stream. A quantitative measure of what constitutes a flash flood is given in terms of the identified temporal parameter, which represents one of the main goal of this study
Sqilxw Educator Rising: Relationality as Methodology in a Social Work Abolitionist Framework
No full textWai, iskwis (my name is), Percy Lezard. Sqilxw ways, personal introductions come before any other words. I am outma sqilxw I was born into a family of sexʷwrmin̓ (firekeepers). This research demonstrates how I as a sqilxw stamya? educator have been able to survive and thrive, through my sqilxw identity and Indigenous knowledges, in mainstream post-secondary education institutions. I have used myself as both the subject and researcher within the social context of post-secondary social work settings, with an insider’s vantage point to chronicle my own pedagogical transition, using the qualitative methodology of relationality. Through my interpretations and reflections about two post-secondary programs, I use comparison to highlight the complexities of their strengths and inadequacies.
This work includes my account as an Indigenous scholar working within a college program grounded in feminist theory, and a university department grounded in an anti-oppression/anti-racism framework. It explores experiences of anti-Indigenous racism, cis-sexism, pushback for my position of solidarity with Black liberation, and oppressions within a disability justice framework.
Using the methodology of relationality, I share the experiences I have encountered and the problems I have faced, to facilitate an understanding of the processes of transition. As the genre of qualitative research brings the reader closer to the subculture studied through the experiences of the author, my work serves to provide an evaluation and insights into the cultures of these two learning environments.
Data gathering consisted of a reflexive journal, my personal calendar, faculty agendas, staff memos, and reflective analysis. As well, in each of the institutions, I was able to gather support and insight through ceremony and interactions with Knowledge Keepers and Elders. In this way, I was able to reflect upon teachings and to apply Indigenous knowledges to my work. These research tools were used to capture the experiences of my transition.
