Masculinities and Femininities: Romance and Authenticity on American Dating Apps
The phenomenon of dating apps like Tinder, Bumble, and Grindr display the way image-based technologies allow for a new visual literacy. This study investigates how the experience of using dating applications (apps) related to Giddens’s notion of romance and explored the way visual literacy was constructed through discourses of authenticity. How do young Americans construct their social worlds through everyday actions and interactions on dating apps? How is romance re-conceptualized through dating apps, and what are the consequences of dating apps on gender identity and courtship?
A qualitative, mixed methods approach was used to gather data. An online survey was distributed and semi-structured interviews were conducted. Results were triangulated to gain insight on notions of romance, gender identity, and visual literacy based on discussions of image codes and dating app use. The sample was Americans and people living America between ages 20-29 who used dating apps.
The research demonstrates that the journalistic media’s discourses perpetuate stigmas of dating apps as virtual spaces for hooking up, when in fact they are used in complex ways that sustain notions of romance and solidify feelings of identity. Additionally, it establishes that authenticity is a primary factor in selecting profile images and communicating on dating apps
Behavioral Indicators in Air Traffic Control: Detecting and Preventing Performance Decline
Air traffic controllers are responsible for the safety and efficiency of air traffic and therefore must maintain a consistently high standard of performance. However, performance can be negatively affected by factors such as workload and fatigue, potentially leading to performance decline and performance-related incidents. Real-time identification of negative influences would facilitate timely implementation of supportive strategies prior to performance decline. The current study aimed to explore the concept of ‘behavioral indicators’ to identify when a controller was reaching a performance limit. A second aim was to capture behavioral indicators associated with performance influencing factors. A total of 65 controllers spanning Tower, Approach and Enroute facilities across the United States of America were interviewed. Findings revealed that controllers were familiar with the concept of behavioral indicators, and that indicators were associated with specific performance-influencing factors. Implications for implementing behavioral indicators training in control environments are discussed
Geology of the Archean Côté Gold Au(-Cu) intrusion-related deposit, Swayze Greenstone Belt, Ontario
The Côté Gold Au(-Cu) deposit is a low-grade, large-tonnage type deposit with an
indicated resource of 269 Mt averaging 0.88 g/t Au (7.61 M oz) and an inferred resource of 44
Mt averaging 0.74 g/t Au (1.04 M oz) at a cut-off grade of 0.3 g/t Au. The deposit is located in
the Swayze greenstone belt (SGB), part of the larger and gold-rich Abitibi Subprovince and is
the first large gold deposit to be discovered in the SGB.
The deposit is hosted by multi-phase tonalite, diorite and quartz diorite intrusions of the
Chester intrusive complex (CIC), a multi-phased, laccolith-shaped synvolcanic intrusion.
Crosscutting relationships suggest coeval emplacement of the host rocks and high-precision UPb
ID-TIMS zircon geochronology results constrain the CIC to ca. 2741 to 2739 Ma. Although a
close temporal relationship exists between the tonalite and dioritic phases, they appear to be
petrogenetically unrelated. The CIC is demonstrated to be petrologically, texturally and
geochemically similar to low-Al tonalite-trondhjemite-diorite composite intrusions known to
underlie VMS-type mineralization. The CIC was emplaced into tholeiitic mafic metavolcanic
rocks of the Arbutus Formation that are interpreted to have formed in a back-arc environment.
The CIC is coeval and cogenetic with the felsic to intermediate rocks of the Yeo Formation.
Emplacement of the CIC into a shallow crustal level is inferred based on the incorporation of
screens and inclusions of the Yeo Formation, consistent with the presence of textures, such as
granophyres, miarolitic cavities and pegmatites, and Al-in hornblende geobarometry results of
≤1.3 ± 0.6 kbars. The intrusive complex is intruded by several younger and petrogenetically
unrelated dike phases, as well as overprinted by regional deformation events.

The deposit has a large ore envelope (1200 m by 300 m) within which several styles of
mineralization (breccias, disseminations and veins) that are co-spatial and cogenetic to
hydrothermal alteration are recognized. The hydrothermal stages consist of: (1) a rare series of
gold-bearing amphibole-rich veins and breccias spatially restricted to the south and central parts
of the deposit; (2) an extensive, main-stage biotite alteration that is centred on Au- and Cubearing
hydrothermal biotite breccia bodies. Outwards from the breccia are veins (stockworks
and sheeted arrays) and disseminations; (3) an extensive, Au ± Cu-bearing fracture-controlled
and replacement-style muscovite alteration in the centre of the deposit; (4) an unmineralized
fracture-controlled and disseminated epidote alteration that is localized to the north of the
deposit; (5) a texturally destructive albite alteration occurs in the central part of the deposit; and
(6) chlorite alteration that overprints biotite alteration. Drill core observations suggest that all the
hydrothermal events, except chloritization, broadly overlap with magmatism and are crudely
zoned on the deposit scale; chloritization is considered to be metamorphic in origin.
To constrain the timing of hydrothermal events U-Pb ID-TIMS, SHRIMP and LA ICPMS
dating of four hydrothermal titanites from amphibole and albite alteration assemblages and
Re-Os dating of two molybdenite samples were analyzed. The hydrothermal titanite ages are
centred on a ca. 2740 Ma and the molybdenite ages are 2736.1 ± 11.4 Ma and 2746.8 ± 11.4 Ma.
These ages overlap with magmatism and strongly support a syn-intrusion timing for alteration
and gold mineralization. Importantly, this age represents a new metallogenic gold event in the
Abitibi Subprovince. In addition, two rutile ages at ca. 2667 Ma were obtained and indicate the
deposit was affected by subsequent thermal events, such as regional metamorphism.
Several of the alteration types (i.e., amphibole, biotite, muscovite and epidote) are
considered to be genetically related to the dioritic phases of the CIC based on relative timing,
v
distribution, mineralogy and mineral chemistry and whole-rock geochemistry. The progressive
crystallization of the dioritic magma chamber is considered to have resulted in the generation of
mineralized magmatic-hydrothermal fluids that are thought to be responsible for generating the
Côté Gold deposit. The sequence of alteration types, their zonation in the deposit and their
chemistry (i.e., gains and losses, REE patterns, metal associations and isotopes) is consistent
with the early hydrothermal stages (i.e., amphibole and biotite) having formed from high
temperature magmatic-derived dioritic fluids and the later alteration types (i.e., muscovite and
epidote) having formed from cooling magmatic fluids mixed with seawater.
The development of albite alteration is thought to be the result of volatile exsolution of
tonalite based on its syn-intrusion timing and the Na-rich nature of the fluids. Although albite
alteration may be gold-bearing, the erratic distribution of the mineralization and the leaching
capacity of fluids suggest earlier gold was remobilized during this event.
Considering the characteristics of the host rocks, the demonstrated overlap of magmatic
and hydrothermal events at ca. 2740 Ma, the nature and distribution of alteration, the style of the
associated mineralization and the geochemical characteristics of the hydrothermal fluids the Côté
Gold deposit is considered to be intrusion-related in origin and formed in a manner similar to
Phanerozoic porphyry-type deposits.Doctor of Philosophy (PhD) in Mineral Deposit and Precambrian Geolog
Video capture virtual reality as a flexible and effective rehabilitation tool
Video capture virtual reality (VR) uses a video camera and software to track movement in a single plane without the need to place markers on specific bodily locations. The user's image is thereby embedded within a simulated environment such that it is possible to interact with animated graphics in a completely natural manner. Although this technology first became available more than 25 years ago, it is only within the past five years that it has been applied in rehabilitation. The objective of this article is to describe the way this technology works, to review its assets relative to other VR platforms, and to provide an overview of some of the major studies that have evaluated the use of video capture technologies for rehabilitation

From a Place of Love: The Experiences of Birthing in a Black-Owned Culturally-Centered Community Birth Center
Introduction: Racial and ethnic disparities in perinatal health outcomes are among the greatest threats to population health in the United States. Black birthing communities are most impacted by these inequities due to structural racism throughout society and within health care settings. Although multiple studies have shown that structural racism and the disrespect associated with this system of inequity are the root causes of observed perinatal inequities, little scholarship has centered the needs of Black birthing communities to create alternative care models. Leaning on reproductive justice and critical race theoretical frameworks, this study explores good birth experiences as described by Black birthing people. Methods: Thematic analysis of two focus groups and three one-on-one interviews conducted with clients at a Black-owned free-standing culturally-centered birth center (n=10). Results: We found that Black birthing persons’ concerns centered on three main themes: agency, historically- and culturally-safe birthing experiences, and relationship-centered care. Many participants pointed directly to past experiences of medical mistreatment and obstetric racism when defining their ideal birth experience. Conclusion: Black birthing people seeking care from culturally-informed providers often do so because they have been mistreated, disregarded, and neglected within traditional care settings. The needs articulated by our study participants provide a powerful framework for understanding alternative patient-centered models of care that can be developed to improve the care experiences of Black birthing people in the pursuit of birth equity
Employee Green Behavior: A Meta-Analysis
Due to climate change, the need to protect biodiversity and reduce pollution, and governmental regulations, many organizations are aiming to become more environmentally sustainable. In this context, researchers and practitioners are increasingly interested in the construct of employee green behavior (EGB). EGB has been considered by numerous empirical studies over the last two decades and its associations with demographic characteristics, individual differences, workrelated perceptions, and job attitudes. To systematically synthesize the rapidly growing literature on EGB, we conducted a meta-analysis (k = 135 independent samples; total N = 47,442 employees). Results showed positive associations between EGB and, for example, proenvironmental attitudes, corporate social responsibility, and green psychological climate. We further report the results of a meta-analytic path model based on the theory of planned behavior, which showed that pro-environmental attitude, norms, perceived behavioral control, and intentions positively predicted EGB
