An Aching for Affection

As humans, we’ve needed companionship from the beginning of time. Therefore, what does a true relationship look like in today’s society? In this world of newly emerging relationships, many people have either experienced, seen, or heard of a toxic relationship. This article dives deep into what makes a toxic relationship, how to notice the red flags, and how to ultimately fix or end it

Learning First-Order Definitions of Functions

First-order learning involves finding a clause-form definition of a relation from examples of the relation and relevant background information. In this paper, a particular first-order learning system is modified to customize it for finding definitions of functional relations. This restriction leads to faster learning times and, in some cases, to definitions that have higher predictive accuracy. Other first-order learning systems might benefit from similar specialization.Comment: See http://www.jair.org/ for any accompanying file

Hermitian and skew hermitian forms over local rings

We study the classification problem of possibly degenerate hermitian and skew hermitian bilinear forms over local rings where 2 is a unit

Disability

People with disabilities (PWD) are the fastest growing minority social group in the world. Moreover, this group is one in which many, if not all individuals, will eventually join due to accidents, injuries, illnesses, wear and tear on aging bodies, and genetic factors. Disabilities can be physical, cognitive, social, and/or emotional. The disability community overlaps with people of all races, ethnicities, age groups, genders, sexual orientations/ expressions, and socioeconomic statuses, although PWD are overrepresented among people who are economically disadvantaged and under-served in health care, environmental safety, nutrition, and other basic needs. While the proportion of people with disabilities increases with age, the majority of people with disabilities remains under the age of 65

Textually Mediated Labour Activism: An Examination of the Ladies Auxiliary of the Canadian Mine Mill & Smelter Workers Union, 1940s-1960s

This paper examines the activism of the Ladies Auxiliary of the Mine Mill and Smelter Workers Union – Canada (MMSW) in the 1940s and 1950s. Drawing on Institutional Ethnography (IE), this paper examines the work of individual MMSW Auxiliary locals across Canada and the ways in which localized political action was coordinated through texts. The paper focuses on how Ladies Auxiliary locals activated two kinds of texts, the MMSW Ladies Auxiliary (LA) Constitution and the district and national Auxiliary newsletters, and examines how these texts coordinated Ladies Auxiliary members’ union work. The paper reveals the political organizing efforts of the LA women within their own locals, the MMSW union, and in broader political movements. In doing so, this paper challenges the prevailing notion that Auxiliaries merely served their male union counterparts in times of labour disputes

Actin filament assembly by bacterial factors VopL/F: Which end is up?

Competing models have been proposed for actin filament nucleation by the bacterial proteins VopL/F. In this issue, Burke et al. (2017. J. Cell Biol. https://doi.org/10.1083/jcb.201608104) use direct observation to demonstrate that VopL/F bind the barbed and pointed ends of actin filaments but only nucleate new filaments from the pointed end
