Surfacing, Voicing and Signalling Freedom in Relational Performance: Cheryl L’Hirondelle and Camille Turner’s Freedom Tours

The marking of colonial narratives mapped as histories onto Canada are reinforced on almost every boat, train, or rail tour in Canada. In Freedom Tours (2017) for LandMarks2017/Répéres2017, by artists Cheryl L’Hirondelle and Camille Turner the artists disrupted these entrenched histories hosting two sailings with tour narration. Thes narrated tours featured narratives that stemmed from Cree worldview and Caribbean diasporic perspectives. In L’Hirondelle and Turner’s work they built an architecture of songs unsung and stories untold in a temporal space- a boat tour in the waters in and around the Thousand Islands National Park. In this text I revisit the process of working with these artists to reveal the ways in which their work while being joyous also signaled the ways in which colonial histories drown out Indigenous, Black and People of Colour narratives in Canada. The historic settler alteration of waterways and borders within the Thousand Islands National Park has meant that some islands, previously visited by Indigenous people to harvest maple sap, are no longer above water. In this paper I want to be that island resurfacing sweet syrup, rising in these unstable waters to offer truths to Canada’s colonial narrative.

Lost in transition: The effects of transitioning between firearms and electronic control devices (ECDs) on perception-response times (PRTs)

The research described in this article tested the perception-response times for experienced police officers to transition from a firearm to a TASER and from a TASER to a firearm. The theoretical models and police training on use of force have largely ignored the temporal space between force modalities. Escalating through force modalities has by default been treated as equivalent, in task and timing, to deescalating through force modalities. This study employed a randomized controlled experiment using a police firearms training simulator and 139 active law enforcement officers. The average perception-response time for transition from a TASER to a firearm was 2.49 seconds for experienced police officers in response to an anticipated visual stimulus in a laboratory setting. The average perception-response time for transition from a firearm to a TASER was 4.7 seconds for experienced police officers in a response to an anticipated visual stimulus in a laboratory setting. 70% of the officers that participated in the study had never participated in department training that required them to transition between a firearm and a TASER. The findings demonstrate that moving from TASER to firearm and from firearm to TASER are not equivalent tasks. In the case of firearms and TASERs, it is significantly faster to move up the force continuum—from TASER to firearm—than it is to move down the force continuum. This research has implications for police training, tactics, policy, research, and post hoc investigations involving the use or potential use of force.

Retrograde Spread of Buccal Space Infection into Temporal Space with Temporal Muscle Necrosis in a Medically Compromised Patient - A Case Report

Superficial temporal space lies between the temporal fasciae. Abscess in the temporal and infratemporal space is very rare. They develop as a result of the extraction of infected maxillary molars. Temporal space infections or abscesses can be seen in the superficial or deep temporal regions. A 65 - year - old male patient reported with a complaint of painful swelling over the right cheek and restricted mouth opening with a history of extraction of second mandibular molar before four weeks. On examination, an ill-defined diffuse swelling was seen. Treatment was started with IV empirical antibiotics and planned for surgical drainage. Surgical drainage of the abscess in the temporal space was done along with debridement of the necrosed temporalis muscle. Infections of the maxillofacial region are of great significance to general dentists and maxillofacial surgeons. They are of clinical importance as they are commonly encountered, and are also challenging as timely intervention is needed to prevent fatal complications. The infections arising from the tooth are initially confined to the alveolar bone and surrounding periosteum. They spread along the path of the least resistance to the cortical plates. Once the infection penetrates the cortical plates, they reach the muscle plane.1 If the infection perforated is above the muscle attachments, it’s confined to an intraoral abscess. If the cortical plates are perforated below the muscular attachments, extraoral swelling develops. The next barrier is the periosteum which is strong and elastic in nature. Once the periosteum is breached, infections reach the soft tissue planes, the fascia. Most of the infections are confined to a particular space and the surrounding fascia. Based on the toxins produced by the microorganisms, the infection can spread to adjacent spaces and even retrograde. Common deep space infections are Ludwig's angina followed by peritonsillar, submandibular, and parotid abscesses. 2 Infratemporal and temporal space infections are rarely compared to other deep space infections. Many etiological factors form the base for the infections of deep spaces, dental caries, extraction of infected, non-infected tooth maxillary sinusitis, tonsillitis, maxillary sinus fracture, temporomandibular arthroscopy, drug-induced infections. Infections of odontogenic origin, spreading along infratemporal and temporal space are most common with maxillary molars followed by mandibular molars. We report a case of retrograde spread of buccal space infection into temporal space secondary to mandibular tooth extraction.

Linguistic and Discursive Features of Mining News Discourse in the Philippines

The Philippines is one of the mineral-rich countries in the world with an estimated US$840 billion worth of untapped mineral wealth, catapulting the mining industry as a significant economic player providing substantial contribution to the national revenue and generating employment opportunities for the Filipino people. However, the detrimental impact of mining to the country has also been heavily criticized as it causes massive potential destruction to environment and wildlife ecology such as acid mine drainage and contaminant leaching, soil erosion, and tailing impoundments among others. These conflicting interests are reflected in the mining discourses stoked or dimmed by media, which influence the readers’ construal of meanings in the mining texts, social actors’ roles in the mining industry, and the urderlying contexts of the mining reality. Drawing on critical discourse analysis, this study described the linguistic and discursive features of Philippine mining discourse in media texts. The study used 224 news articles published by three online portals within five years. Local news reports and peripheral discourses obtained through interviews with local “symbolic elites” in the identified mining communities and other archival documents supplemented the news texts. The UAM Corpus Tool, a software for linguistic tagging, complemented the manual analysis in identifying the social actor theme. Findings revealed that government actions, economic phenomenon, and political actors are the most prevalent themes in the mining news reports. Moreover, results showed that local news tends to focus more on the mining’s environmental impact, whereas the national news tends to put more premium on the mining’s economic impact. This means that the media allotted a much lesser spatio-temporal space for the environment and Indigenous Peoples’ cause. The findings further invalidate the assumptions that mining discourse is primarily concerned with environmental related issues.

Temporal (t > 0) Space and Gravitational Waves

I will begin with the nature of our temporal (t > 0) universe, since without temporal space there would be no gravitation force because gravitational field cannot be created within an empty space. When we are dealing with physical realizability of science, Einstein’s relativity theories cannot be ignored since relativistic mechanics is dealing with very large objects. Nevertheless I will show that huge gravitational waves can be created by a gigantic mass annihilation only within a temporal (t > 0) space. Since gravitational energy has never been consider as a significant component within big bang creation, I will show it is a key component to ignite the big bang explosion, contrary to commonly believed that big bang explosion was ignited by time. I will show a huge gravitation energy reservoir induced by a gigantic mass had had been created over time well before the big bang started. Since the assumed singularity mass within a temporal (t > 0) had had gotten heavier and heavier similar to a gigantic black hole that continuingly swallows up huge chunk of substances within the space. From which we see that it is the gravitational force that triggers the thermo-nuclei big bang creation, instead ignited by time as postulated. Aside the thermo-nuclei creation, it had a gigantic gravitational wave release as mass annihilates rapidly by big bang explosion. From which we see that it is the induced gravitational reservoir changes with time, but not the induced gravity changes (i.e., curves) time–space. In other words if there has no temporal (t > 0) space then there will be no gravitational waves.

Acute Sub temporal and Infratemporal Dumbbell Abscess Secondary to Tooth Extraction: Case Report

To present a case of acute temporal and infratemporal dumbbell abscess following tooth extraction and discuss the possible anatomic pathways of spread of odontogenic infections. This is a case of right maxillary tooth extraction following which he developed local infection that spread to the temporal and sub temporal space. The history and examination revealed the infection spreading to the buccal and sub temporal space with trismus and feeding problems. Intraoral and external drainage along with antibiotics led to the resolution of the abscess. Of the many complications of tooth extraction infection spreading along the temporalis with formation of a dumbbell abscess can lead to severe discomfort and septicemia if not detected and treated early. A case with successful management and result are discussed.

Effect of neutral winds on the creation of non-specular meteor trail echoes

Non-specular meteor trail echoes are radar reflections from plasma instabilities that are caused by field-aligned irregularities. Meteor simulations are examined to show that these plasma instabilities, and thus the associated meteor trail echo, strongly depend on the meteoroid properties and the characteristics of the atmosphere in which the meteoroid is embedded. The effects of neutral winds, as a function of altitude, are analyzed to understand how their amplitude variability impacts the temporal–space signatures of non-specular meteor trail echoes present in very high-frequency (VHF) radar observations. It is found that amplitudes of the total horizontal neutral wind smaller than 0.6 m s−1 do not provide the right physical conditions to enable the genesis of non-specular meteor echoes. It is also found that a 0.0316 µg meteoroid traveling at 35 km s−1 can be seen as a meteor trail echo if the amplitudes of horizontal neutral winds are stronger than 15 m s−1. In contrast, a 0.316 µg meteoroid, traveling at the same speed, requires horizontal winds stronger than 1 m s−1 to be visible as a meteor trail echo. The neutral velocity threshold illustrates how simulations show that no trail echo is created below a critical wind value. This critical wind value is not mapped directly to radar observations, but it is used to shed light on the physics of meteor trails and improve their modeling. The meteor simulations also indicate that time delays on the order of hundreds of milliseconds or longer, between head echoes and non-specular echoes, which are present in VHF backscatter radar maps, can be a consequence of very dense plasma trails being affected by weak horizontal neutral winds that are smaller than 1 m s−1.

A Modular Framework for the Life Cycle Based Evaluation of Aircraft Technologies, Maintenance Strategies, and Operational Decision Making Using Discrete Event Simulation

Current practices for investment and technology decision making in aeronautics largely rely on regression-based cost estimation methods. Although quick to implement and easy to use, they suffer from a variety of limitations, both in temporal space and scope of applicability. While recent research and development in this area addresses these to a certain extent, aerospace engineering still lacks a flexible and customizable valuation framework. To this end, a generic environment for economic and operational assessment of aircraft and related products named LYFE is presented. This tool employs a discrete event simulation which models the product life cycle from its order through decades of operation and maintenance until disposal. This paper introduces its key characteristics and default methods alongside its modular program architecture. The capabilities are demonstrated with a case study of on-wing engine cleaning procedures which are triggered by a customized decision making module. Thereby, the impact on engine health, fuel efficiency and overall economic viability is quantified. On the whole, the framework introduced in this paper can be used to analyze not only physical products but also operational procedures and maintenance strategies as well as specified decision making algorithms in terms of their impact on an aircraft’s or system’s life cycle.

Temporal Structure in the Novel “The Killer of Hamza (Qaatil Hamza)” by Najeeb Gillani

Temporal Structure is an essential element of the narrative works as well as a component of narratives. It has become a prominent issue in literary criticism in 20th century. Because time structure plays an enormously important role in the construction of story/novel, the other elements of the novel/story cannot be viewed without temporal space. It is temporal space/structure on which the events of the story are based and rhythm, flow and continuity of the story can be maintained by temporal space. Events cannot exist out of the temporal structure of the story. This study deals with the temporal structure and its role in the novel “Killer of Hamza” by Najeeb Gillani and attempts to reveal the method of constructing time in the novel by standing on temporal order and temporal paradoxes both types of retrieval and anticipation, as well as the structure of the rhythm of time such as the technique of speeding narration with its movements (The dialogue scene, the descriptive position) and the frequency of the three types (solitary, repetitive, author). In addition, the study concludes the discussion based on the findings.
