Algebraic weak factorisation systems II: categories of weak maps

We investigate the categories of weak maps associated to an algebraic weak factorisation system (AWFS) in the sense of Grandis-Tholen. For any AWFS on a category with an initial object, cofibrant replacement forms a comonad, and the category of (left) weak maps associated to the AWFS is by definition the Kleisli category of this comonad. We exhibit categories of weak maps as a kind of "homotopy category", that freely adjoins a section for every "acyclic fibration" (=right map) of the AWFS; and using this characterisation, we give an alternate description of categories of weak maps in terms of spans with left leg an acyclic fibration. We moreover show that the 2-functor sending each AWFS on a suitable category to its cofibrant replacement comonad has a fully faithful right adjoint: so exhibiting the theory of comonads, and dually of monads, as incorporated into the theory of AWFS. We also describe various applications of the general theory: to the generalised sketches of Kinoshita-Power-Takeyama, to the two-dimensional monad theory of Blackwell-Kelly-Power, and to the theory of dg-categories.Comment: 30 pages, final journal versio

Two-dimensional regularity and exactness

We define notions of regularity and (Barr-)exactness for 2-categories. In fact, we define three notions of regularity and exactness, each based on one of the three canonical ways of factorising a functor in Cat: as (surjective on objects, injective on objects and fully faithful), as (bijective on objects, fully faithful), and as (bijective on objects and full, faithful). The correctness of our notions is justified using the theory of lex colimits introduced by Lack and the second author. Along the way, we develop an abstract theory of regularity and exactness relative to a kernel--quotient factorisation, extending earlier work of Street and others.Comment: 37 page

The Deaf & Law Enforcement Listening Though Deaf Eyes: A Grounded Theory Approach

This paper examines the perceived and practical schism between deaf society and the police when the deaf attempt to obtain police services. The paper challenges current police culture and operating procedures, which tend to marginalize deaf society and largely ignore the mandates contained in the Americans with Disabilities Act (ADA). This qualitative research project is focused upon perceived law enforcement practices and culture through a multi-layered study of police customs, law, policy, and standard operating procedures as experienced, perceived, and reported by deaf individuals. A constructivist grounded theory approach was used to examine the way law enforcement is perceived by the Deaf, Deaf-Blind, and Hard-of-Hearing community. Open-ended interviews were conducted to gather data. The data gathered will be shared in the hopes it will impact the criminal justice system’s approach to deaf individuals, culture, and issues. The data casts a critical light upon the limitations in policing and the lack of attention to historically important legislation

Using Suites of Criteria to Recognize Pre-Flood, Flood, and Post-Flood Strata in the Rock Record with Application to Wyoming (USA)

We propose a method using suites of criteria to help establish pre-Flood, Flood and post-Flood strata. Our method is independent of chronostratigraphic indicators (that is, radioisotope dates and zone fossils); instead it relies on other criteria. Application of this model is made using the lithostratigraphic section from Wyoming and vicinity (USA) as an illustration of how the criteria model should be used. Not only can this model be used to help more confidently determine Flood boundaries, but it might be used as a test to see whether we can rely on chronostratigraphic or biostratigraphic units to determine Flood boundaries elsewhere. Properly understanding which strata belong to the pre-Flood, Flood, and post-Flood periods by recognizing large-scale patterns or suites of criteria, will help us more fully understand the biostratigraphic patterns found within the rock record

Use of GFCF Diets in children with ASD. An investigation into parents' beliefs using the theory of planned behaviour

Gluten free/Casein free (GFCF) diets are one of the most common types of Complementary and Alternative Medicines (CAM) used in Autism Spectrum Disorders (ASD) despite little evidence to support positive effects. There has been no theory driven literature that has investigated parent's reasons for their use. The Theory of Planned Behaviour (TPB) was used to examine parent's intentions to use GFCF diets for their child with an ASD. Treatment and causal beliefs were also examined. Parents (n=33, children aged 3-17 years) were influenced by anticipated regret, positive outcomes and attitude. Future interventions should provide information to parents and health professionals about the possible causes of ASD and therapy options which are in line with current recommendations
