The Relationship

In British Columbia, alkali-aggregate reaction (AAR) in concrete has not historically been a well-studied, and thus well-understood, mechanism. This paper provides a synopsis of the current state of what is known of AAR in British Columbia. The foci of the paper are (i) locations of AAR in concrete, (ii) the AAR characteristics of aggregates in British Columbia, (iii) the relationship between geology and AAR, and (iv) preventative methods and prescriptions used to prevent or mitigate AAR in British Columbia.Key words: alkali-aggregate reaction, British Columbia, concrete, aggregate, expansion test.

This article engages the reader in comparing the Métis List of Rights, originally authored by Louis Riel, with the current state of Indigenous child welfare in British Columbia and Canada. The relationship between children’s resiliency and cultural resiliency is explored. Using a critical lens, a framework defining the progression of social regulation is presented. This paper begins by setting out the framework with its accompanying nine aspects: profit, competition, self-interest, justice, rights, duties, love, compassion and devotion. The discussion acknowledges children as sacred which allows us to move beyond conservative and socialist ideals. Then there is a discussion on the aspects of the Métis List of Rights with comments respecting the symbolic and literal application of the aspects to reclaiming Indigenous child welfare. Finally the article ends with recommendations for holistic pathway for reform.

The Relationship

“Canadian cinema.” The term may appear self-evident but is problematic. First, one may question the value of national approaches to culture, especially here, in Quebec and Canada, where the debates over the Nation seem interminable, and especially now, in an era of globalization. Next, one may question the value of media-centered approaches to culture, especially when the successive waves of the “digital revolution” have blurred the boundaries between technologies and among artistic practices. Rather than try to survey “important” fiction films for theatres in Quebec or Canada, this essay adopts another point of view to examine the presence of cinema in Montreal museums over the past few years by focusing on three singular exhibitions. It may well be symptomatic of the current state of film in Quebec and Canada—but also, paradoxically, everywhere else—and says much about the relationship between medium and nation, the expansion of cinema beyond the movie theatre, and the internationalization of culture.

The Relationship

Slopes in weakly cemented glaciolacustrine sediments in the Morkill River valley in the Canadian Rocky Mountains stand at up to 70°. Based on field and laboratory observations it appears that a contributing factor to instability is the softening of the soils by frost action and the leaching of calcite cement. Field density profiles demonstrated increased density and carbonate content with an increase in depth. Laboratory tests of carbonate content indicated a positive correlation between calcium carbonate and density in the glaciolacustrine sediments. The relationship was strongest in sands, in which leaching and dissolution were important components of softening. In clays, frost action was the dominant component of softening. Freeze-thaw tests showed a 50% decrease in strength after one cycle of freeze and thaw in the silts and clays.Key words: landslide, cemented, glaciolacustrine sediments, British Columbia.

The fecundity and egg retention of anadromous female sockeye salmon (Oncorhynchus nerka) collected during 1971–82 from several stocks in British Columbia undergoing controlled fertilization to enhance adult sockeye production were examined. The relationship between egg number and postorbital–hypural length based on 863 females representing 14 stocks was not consistent between all age-types, stocks, and years, probably because of inadequate sample size in some instances. Combined samples, however, revealed a significant positive relationship between postorbital–hypural length and egg number for age 1.2, 1.3, and 2.2 females. Mean absolute fecundity for the respective age-types was 3218, 4125, and 3544 eggs. For samples of 10 or more females, significant stock and annual differences were detected when individual mean absolute fecundity was adjusted to a postorbital–hypural length of 447 mm, but not for females of different age. A comparison of mean fecundities for coastal stocks with historical data for interior British Columbia stocks suggests that coastal stocks are 18% more fecund than interior stocks. Possible causal mechanisms for this regional difference are hypothesized. Examination of 796 carcasses (representing five stocks) for egg retention revealed a range from totally spawned to totally unspawned females, with 56% of the carcasses containing 20 eggs or less and 68% containing 50 eggs or less. The mean egg retention based on all samples combined was estimated to be 6.5% of the mean individual fecundity. This value was reduced to 3.9% when stock means were averaged.

The Relationship

Drought tolerance of trees may be affected by competition, but most studies quantifying the relationship do not consider the effect of stem clustering. Trees are often clustered in interior Douglas-fir (Pseudotsuga menziesii var. glauca (Mayr) Franco) forests near the grassland interface in central British Columbia due to past harvesting practices or habitat management for mule deer (Odocoileus hemionus hemionus (Rafinesque, 1817)). Climate change projections indicate continued increases in temperature, an outcome that would stress trees growing in dry environments. Trees placed in different states of competition by mechanical harvesting in the 1970s were sampled to provide a 40-year comparison of three levels of competition during 1–2 year droughts. Tree-ring analysis was used to assess the reduction in growth during drought years and resumption of growth in subsequent years. A clear separation of growth rates was evident between open-growing trees, trees on the edge of harvesting trails, and trees within the unharvested interior. Edge trees had intermediate growth rates but no differences were found in the long-term climate–growth relationship compared with open-growing trees. Both Edge and Open classes showed less relative growth reduction during droughts than Interior trees growing between harvest trails. Precipitation throughfall rates and competition for resources are likely driving short-term drought tolerance in combination with other factors.

The edge of chaos has been constantly viewed as a metaphor for the current state our world: a constant coexistence of order and disorder. [...] Several authors working within education and organizational environments have highlighted that creators must perform at the ‘edge of chaos’ in order to produce creative and adaptive solutions. [...] This paper aims to discuss the dichotomy between order and disorder in the creative environment (socio- physics aspects) of architecture students from the Universidade Federal do Rio Grande do Norte, Brazil. Particularly, this paper focuses on students who are working on their Final Graduation Work (FGW), because, unlike other tasks, this activity is completed away from the classroom, in a space 'in-between' – in-betweenwork and home spaces, in-between the collective and the individual, in-between order and chaos.

There is much pessimism as to the current state of Sino-American relations, especially since the onset of the COVID-19 pandemic in January 2020. Such pessimism has led to some scholars and commentators asserting that the Sino-American relationship is on the cusp of either a new Cold War or, even more alarmingly, something akin to the Peloponnesian War (via a Thucydides Trap) whereby the United States might take pre-emptive measures against China. This article rejects such analogizing and argues that, due to important technological advancements found at the intersection of the digital and fourth industrial revolutions, most of the real competition in the relationship is now occurring in cyberspace, especially with regards to the aim of asserting narratives of truth. Two key narrative battlegrounds that have raged since the onset of the COVID-19 pandemic are examined: where was the origin of the COVID-19 pandemic? and who has had the most successful response to the COVID-19 pandemic?. This article shows that Sino-American competition in cyberspace over asserting their narratives of truth (related to the COVID-19 pandemic) is fierce and unhinged. Part of what is driving this competition is the challenging domestic settings politicians and officials find themselves in both China and the United States, thus, the competing narratives being asserted by both sides are predominately for domestic audiences. However, given that cyberspace connects states with foreign publics more intimately, the international aspect of this competition is also important and could result in further damage to the already fragile Sino-American relationship. Yet, whether this competition will bleed into the real world is far from certain and, because of this, doomsaying via historical analogies should be avoided.

The current model for society’s development, based on the unconscious use of natural resources, points to signs of exhaustion, requiring a reflection in order to formulate strategies that overcome the challenge of coexistence between the relationship between man and nature. The use of tools such as sustainable indicators has been shown to be effective in the identification and understanding of socio-environmental phenomena and in the subsequent decision making by public management, assisting in the resolution of problems, and consequently, acting as a resource for sustainable development. This study aims to propose the development of an urban sustainability indicator for the municipality of Umuarama, in the state of Paraná, Brazil. In order to build the indicator, data from different aspects linked to Sach’s sustainability model are to be collected, and later put into statistical treatment to standardize it and make its comparison possible, resulting in its index, which is expected to analyze the current state of the local sustainability and sustainable development.

This paper focuses on sociocultural and language-related issues among Croatian immigrants in Canada. It presents the results of thestudy conducted from November 2018 to February 2019 among Croatian immigrants of different generations in Ontario and British Columbia. Questions included in the questionnaire refer to different aspects of participants’ identity and their (families’) immigration, as well as issues related to their attitudes towards the homeland and engagement in Croatian associations in Canada. Participants were asked to provide feedback on their language acquisition, competence and use, as well as evaluations of the importance of the Croatian language for their identity. The questionnaire also contained questions related to participants’ language use from emotional and cognitive perspectives. Conclusions drawn on the basis of the collected data provide an insight into Croatian immigrants’ language use, the extent of cultural integration and language maintenance, and their attitudes towards the relationship between identity and language.
