description: تندرج هذه الدراسة ضمن مبحث أنثروبولوجيا الصورة، وتستهدف الحفر في الجذور الثقافية المُشكلة لجماليات التعبير الفني في المغرب مع التركيز على فن مخصوص هو السينما. في ذات السياق، سنعمل على تتبع السيرورة التاريخية للتفاعل الثقافي الذي شهده المجتمع المغربي، وذلك عبر تسليط الضوء على خصائص الموارد المختلفة التي نَهَلَ منها التعبير الفني، ونقصد هنا الإشارة إلى تفاعل الموارد الآتية وتلاقحها: المورد العربي-الإسلامي والمورد الأمازيغي والمورد المتوسطي والمورد الإفريقي-صحراوي؛ أما الجزء الثاني من الدراسة فيقتصر على تحليل الأساليب الفنية المُعتمدة في عدد من الأفلام السينمائية المغربية، وذلك لغرض كشف النقاب عن المنطلقات الفكرية الخاصة بالمخرجين المغاربة، والتي تحدد تمثلاتهم للإنسان المغربي، وللتحولات الاجتماعية في المغرب، وأيضا تمثلاتهم حول مكانة كل من المرأة والرجل داخل المجتمع.

Abstract: This study takes part in the topic of the visual anthropology; it aims at digging the cultural roots that shapes the beauty of the artistic expression in Morocco, along with focusing on a specific art which is the cinema. In the same sense, we will track the historical process of the cultural interaction which took place in the Moroccan society, hence we will shed the light on characteristics of the different resources of the artistic expression, we mean here the interaction and the mixture of the following subjects: the Arabic resource, Islam and the Amazigh resources, the Mediterranean and the African resources and Arfican-Saharian source. As for the second part of this study, it will deal with analyzing the artistic techniques of a number of the Moroccan movies in order to uncover the intellectual background of the Moroccan filmmakers; this background determines the representations of the Moroccan people, and the social transformations in Morocco. Additionally, their representations in the status of men and women in the society.
Leave – Stay – Return: Understanding Mobility Trajectories of German Migrants by Choice Moving to and from Canada

description: This dissertation focuses on the mobility trajectories of highly skilled and relatively affluent migrants who move between highly developed countries of the “global North”. While these “migrants by choice” are often seen as “desired immigrants” who hold the privilege to move internationally relatively unrestricted, little is known about their actual migration decision-making behaviour and their lived experiences in their place(s) of destination. To address this research gap, I explore the migration trajectories of German migrants by choice moving to and from Canada as a case study. Drawing on 48 narrative life story interviews with Germans at different stages of their migration trajectories (i.e., the pre-movement phase, the phase of settling down and living in Canada and the phase of return and/or onward movement) I specifically analyse a) their lived experiences in their day-to-day life (including experiences of settlement and integration as well as the place attachments they form during their mobility trajectories to b) understand how these experiences impact their decisions of leaving, staying, returning, or moving onward, i.e., to be internationally mobile. The results demonstrate that emotional or ideational reasons as well as chance were the main drivers behind my interviewees’ movements to Canada. Moreover, the findings underline that migration decisions are often formed in ongoing processes that change and evolve over time and are closely tied to my interviewees’ lived experiences at their local places of destination as well as significant life course events, such as the birth of a child or relationship break-up. Drawing on these findings, I ultimately propose a new and comprehensive model explaining the migration decision-making processes of migrants by choice. In doing so, this dissertation makes five important contributions to the field of migration and mobility studies, namely 1) it challenges the sedentary bias in migration studies; 2) it underlines the importance of moving away from strictly national or transnational perspectives on migration movements; 3) it highlights the importance of considering the lived experiences as well as the challenges and hidden frictions of highly skilled migration movements; 4) it challenges a purely economic or political understanding of migration processes; and 5) it highlights the importance of exploring the dissonance between policy intentions and the actual behaviour of migrants.

description: We present a comprehensive study of the use of value precedence constraints to break value symmetry. We first give a simple encoding of value precedence into ternary constraints that is both efficient and effective at breaking symmetry. We then extend value precedence to deal with a number of generalizations like wreath value and partial interchangeability. We also show that value precedence is closely related to lexicographical ordering. Finally, we consider the interaction between value precedence and symmetry breaking constraints for variable symmetries.

No real advantage of photon subtraction and displacement in continuous variable measurement device independent quantum key distribution

description: We critically analyse the role of single photon subtraction (SPS) and displacement in improving the performance of continuous variable measurement device independent quantum key distribution (CV-MDI-QKD). We consider CV-MDI-QKD with resource states generated by SPS on a displaced two-mode squeezed vacuum state. Optimizing the secret key rate with state parameters reveals that implementing SPS yields no benefits in improving the loss tolerance of CV-MDI-QKD. Additionally, we find that displacement too is not useful in improving the performance of CV-MDI-QKD. While our result is in contradistinction with the widely held belief in the field regarding the utility of SPS and displacement in CV-MDI-QKD, it also calls for a re-examination of the role of non-Gaussian operations in increasing the efficiency of various quantum information processing protocols.

Revealing population-specific differences in lipid content, marine distribution, coastal food webs, and marine foraging of sub-adult Chinook salmon (Oncorhynchus tshawytscha)
Creators: name: Lerner, Jacob
Publisher: name: University of British Columbia
Year: 2024

description: Chinook salmon (Oncorhynchus tshawytscha) are the largest, fattiest, and most diverse species of Pacific salmon and hold immense cultural, economic, and ecological significance. This is especially true in British Columbia (BC), Canada, where they support Indigenous communities, recreational and commercial fisheries, and endangered resident killer whale populations. Chinook spend the majority of their life in the ocean, where 99% of their growth and lipid accumulation occurs. Despite this, in BC, there are many open questions regarding their population-specific marine ecology, such as how much lipid they accumulate, their patterns of marine distribution, and, subsequently, what food webs they encounter and their role in these systems. This dissertation aims to address these questions, first by resolving differences in lipid content among ecologically significant populations of Chinook and then by using stable isotopes analysis of carbon (δ¹³C), and nitrogen (δ¹⁵N) to better understand their population-specific distribution, marine food webs, and trophic ecology. To do this, first, I calibrated a microwave fat meter to accurately measure whole body lipid content of Chinook salmon and then measured population-specific lipid content for Chinook from the Fraser River. In doing so, I demonstrated population-specific levels and seasonal differences in a trait crucial to successful Chinook spawning and valuable to endangered killer whales. Next, through experimental analysis I determined Chinook-specific verification of the assumptions underpinning the application of stable isotope analysis—lipid correction equations and trophic enrichment factors. With these established, I used stable isotopes infer population-specific differences in Chinook distribution and isotopic niche, complementing existing population distributions. Following this, I investigated regional food web structure in these marine foraging grounds, delineating the trophic relationships of the fish species constituting each food web and showing how food chain length varies with increases in primary production in eutrophic coastal ecosystems. Finally, I resolved population-specific regional trophic ecology using bulk and compound-specific SIA, illustrating the relationship between distribution, food webs, and Chinook foraging ecology. This dissertation provides novel analysis and interpretation of population-specific Chinook lipid content, marine ecology, and food webs, with important applications to the management of Chinook in BC and our understanding of the species’ life history.

description: Non-local, inhomogeneous and retarded response observed in experiments is reproduced by introducing the Inhomogeneous Momentum Average (IMA) method to study single polaron problems with disorder in the on-site potential and/or spatial variations of the electron-phonon couplings and/or phonon frequencies. We show that the electron-phonon coupling gives rise to an additional inhomogeneous, strongly retarded potential, which makes instant approximations questionable. The accuracy of IMA is demonstrated by comparison with results from the approximation free Diagrammatic Monte Carlo (DMC) method. Its simplicity allows for easy study of many problems that were previously unaccessible. As an example, we show how inhomogeneities in the electron-phonon coupling lead to nonlocal, retarded response in scanning tunneling microscopy (STM) images.

description: Within the covariant formulation of light-front dynamics, we calculate the state vector of a fermion coupled to identical scalar bosons (the Yukawa model). The state vector is decomposed in Fock sectors and we consider the first three ones: a single fermion, a fermion coupled to one boson, and a fermion coupled to two bosons. This last three-body sector generates nontrivial and nonperturbative contributions to the state vector, and these contributions are calculated with no approximations. The divergences of the amplitudes are regularized using Pauli-Villars fermion and boson fields. Physical observables can be unambiguously deduced using a systematic renormalization scheme we developed. This renormalization scheme is a necessary condition in order to avoid uncancelled divergences when Fock space is truncated. As an example, we present preliminary numerical results for the anomalous magnetic moment of a fermion in the Yukawa model.

description: Complexity theory is a useful tool to study computational issues surrounding the elicitation of preferences, as well as the strategic manipulation of elections aggregating together preferences of multiple agents. We study here the complexity of determining when we can terminate eliciting preferences, and prove that the complexity depends on the elicitation strategy. We show, for instance, that it may be better from a computational perspective to elicit all preferences from one agent at a time than to elicit individual preferences from multiple agents. We also study the connection between the strategic manipulation of an election and preference elicitation. We show that what we can manipulate affects the computational complexity of manipulation. In particular, we prove that there are voting rules which are easy to manipulate if we can change all of an agent's vote, but computationally intractable if we can change only some of their preferences. This suggests that, as with preference elicitation, a fine-grained view of manipulation may be informative. Finally, we study the connection between predicting the winner of an election and preference elicitation. Based on this connection, we identify a voting rule where it is computationally difficult to decide the probability of a candidate winning given a probability distribution over the votes.

description: We introduce NeuroSA, a neuromorphic architecture specifically designed to ensure asymptotic convergence to the ground state of an Ising problem using a Fowler-Nordheim quantum mechanical tunneling based threshold-annealing process. The core component of NeuroSA consists of a pair of asynchronous ON-OFF neurons, which effectively map classical simulated annealing dynamics onto a network of integrate-and-fire neurons. The threshold of each ON-OFF neuron pair is adaptively adjusted by an FN annealer and the resulting spiking dynamics replicates the optimal escape mechanism and convergence of SA, particularly at low-temperatures. To validate the effectiveness of our neuromorphic Ising machine, we systematically solved benchmark combinatorial optimization problems such as MAX-CUT and Max Independent Set. Across multiple runs, NeuroSA consistently generates distribution of solutions that are concentrated around the state-of-the-art results (within 99%) or surpass the current state-of-the-art solutions for Max Independent Set benchmarks. Furthermore, NeuroSA is able to achieve these superior distributions without any graph-specific hyperparameter tuning. For practical illustration, we present results from an implementation of NeuroSA on the SpiNNaker2 platform, highlighting the feasibility of mapping our proposed architecture onto a standard neuromorphic accelerator platform.

description: This study delves into the fundamental properties of graphene and boron nitride (BN) nanostructures, exploring their torsional energy characteristics within the framework of Teleparallel Equivalent of General Relativity (TEGR). By constructing nanocones with disclination defects in these materials, we investigate the linear dependence of torsional energy on the disclination angle, as predicted by TEGR. The qualitative validation of TEGR's energy expression is supported by our simulations, which show a strong correlation between the torsional energy and the disclination angle, consistent with the theoretical predictions. Furthermore, we propose a quantitative analysis by estimating the coupling constant $k$ associated with TEGR through molecular simulations and Density Functional Theory (DFT) calculations. Our results suggest that $k$ reflects the interatomic forces within the materials, providing insights into the nature of spacetime and gravitational interactions on a microscopic scale. These findings not only contribute to our understanding of material physics but also offer implications for the precision and validity of TEGR in describing gravitational phenomena.

description: Constraint propagation is one of the techniques central to the success of constraint programming. To reduce search, fast algorithms associated with each constraint prune the domains of variables. With global (or non-binary) constraints, the cost of such propagation may be much greater than the quadratic cost for binary constraints. We therefore study the computational complexity of reasoning with global constraints. We first characterise a number of important questions related to constraint propagation. We show that such questions are intractable in general, and identify dependencies between the tractability and intractability of the different questions. We then demonstrate how the tools of computational complexity can be used in the design and analysis of specific global constraints. In particular, we illustrate how computational complexity can be used to determine when a lesser level of local consistency should be enforced, when constraints can be safely generalized, when decomposing constraints will reduce the amount of pruning, and when combining constraints is tractable.

description: Relativistic Hartree-Fock-Bogoliubov (RHFB) theory with density-dependent meson-nucleon couplings is presented. The integro-differential RHFB equations are solved by expanding the different components of the quasi-particle spinors in the complete set of eigen-solutions of the Dirac equations with Woods-Saxon potentials. Using the finite-range Gogny force D1S as an effective interaction in the pairing channel, systematic RHFB calculations are performed for Sn isotopes and N=82 isotones. It is demonstrated that an appropriate description of both mean field and pairing effects can be obtained within RHFB theory with finite range Gogny pairing forces. Better systematics are also found in the regions from the stable to the neutron-rich side with the inclusion of Fock terms, especially in the presence of $ρ$-tensor couplings.

description: Delta I=3/2, K to Pi Pi matrix elements are calculated on 68 configurations of quenched 24^3 x 64 lattices using the DBW2 action, and domain wall fermions with L_s=16. The lattice spacing is a^(-1)=1.3 GeV, corresponding to a physical volume of (3.6 fm)^3, which allows us to simulate a pion mass of m_Pi=227.6(6) MeV and a kaon mass of m_K=564(2) MeV. Twisted boundary conditions are used to give the two pions momentum. One twist corresponds to a pion momentum of p=Pi/L=170 MeV, which represents a decay that is nearly on-shell. Results for time separations of 20, 24, 28, and 32 between the kaon and the two pions are computed and an error weighted average is performed to reduced the error. The matrix elements are then found to have errors of order 3-4% for momentum 0 and Pi/L, 7% for momentum sqrt(2)*Pi/L, and 15% for momentum sqrt(3)*Pi/L.

description: A solid-state analogue of Stimulated Raman Adiabatic Passage can be implemented in a triple well solid-state system to coherently transport an electron across the wells with exponentially suppressed occupation in the central well at any point of time. Termed coherent tunneling adiabatic passage (CTAP), this method provides a robust way to transfer quantum information encoded in the electronic spin across a chain of quantum dots or donors. Using large scale atomistic tight-binding simulations involving over 3.5 million atoms, we verify the existence of a CTAP pathway in a realistic solid-state system: gated triple donors in silicon. Realistic gate profiles from commercial tools were combined with tight-binding methods to simulate gate control of the donor to donor tunnel barriers in the presence of cross-talk. As CTAP is an adiabatic protocol, it can be analyzed by solving the time independent problem at various stages of the pulse - justifying the use of time-independent tight-binding methods to this problem. Our results show that a three donor CTAP transfer, with inter-donor spacing of 15 nm can occur on timescales greater than 23 ps, well within experimentally accessible regimes. The method not only provides a tool to guide future CTAP experiments, but also illuminates the possibility of system engineering to enhance control and transfer times.

description: The antibiogram signatures of E. coli O157:H7 (n=46) recovered from irrigation water and agricultural soil samples were assessed using the standard disc diffusion method against a panel of 16 antibiotics and molecular methods. The prevalent antibiotic resistance patterns follow the order: cefuroxime (95.7%), nitrofurantoin (93.5%), ampicillin (73.9%), chloramphenicol (71.7%), cefotaxime (60.9%) and trimethoprim/sulfamethoxazole (58.7%). The antibiotic resistance genes detected in the phenotypically resistant isolates include: tetA, tetB, tetC, catII, sulI, sulII, FOX-, CIT-, MOX-, EBC-type plasmid-mediated AmpC, and blaSHV extended-spectrum beta-lactamase. We conclude that irrigation water and agricultural soil are important reservoirs of multidrug-resistant E. coli O157:H7, hence a potential risk to South Africa’s one-health policy.
The evolution of bark beetle–fungus mutualisms : insights from a hardwood system
Creators: name: Wertman, Debra Lindsay
Publisher: name: University of British Columbia
Year: 2024

description: In mutualisms with bark beetles (Coleoptera: Curculionidae; Scolytinae), fungi benefit from dispersal to new habitats while granting their insect vectors access to resources via their phytopathogenic activities and supplementation of beetle nutrition. Alniphagus aspericollis, the alder bark beetle, is a bole-infesting beetle that kills red alder, Alnus rubra, a nitrogen-fixing hardwood native to the Pacific Coast of North America. Unlike most tree-killing bark beetles, the alder bark beetle is not regularly associated with ophiostomatoid fungi (Ophiostomatales and Microascales), but is instead associated with a previously undescribed species of Neonectria fungus (Hypocreales). I hypothesized that the alder bark beetle–Neonectria sp. nov. association represents a unique bark beetle–fungus mutualism that is similar to bark beetle–ophiostomatoid mutualisms in conifers. I first characterized the branch-overwintering component of the alder bark beetle life cycle, described Neonectria sp. nov. as Neonectria bordenii sp. nov., and developed a qPCR assay to enable detection of N. bordenii from alder bark beetle DNA. I then evaluated the following predictions, at five sites throughout southwestern British Columbia, Canada: (1) the alder bark beetle vectors N. bordenii; and (2) the beetle uses both an aggregation pheromone and N. bordenii to facilitate spatially-clustered mass-attacks on red alders. I tested prediction (1) according to Leach’s postulates, using qPCR and culturing methods to reveal that N. bordenii was present on emergent alder bark beetles at frequencies consistent with established bark beetle–fungus mutualisms, and that attacking beetles transmitted N. bordenii into red alders. To test prediction (2), I quantified patterns of host colonization by alder bark beetles in one-hectare plots, demonstrating spatial clustering of attacks on trees that supports the existence of an alder bark beetle aggregation pheromone. Previously attacked trees were more likely to be attacked and produced more offspring than previously unaffected trees, suggesting a mutualistic function of N. bordenii. Potentially high rates of alder bark beetle population increase were observed, raising concerns of widespread red alder decline. My research provides valuable insights into the evolution of bark beetle–fungus mutualisms by expanding upon known associations to include a hardwood-killing bark beetle and its unique putative mutualist.

description: It is shown that the pair plasmas with small temperature asymmetry can support existence of localized as well as de-localized optical vortex solitons. Coexistence of such solitons is possible due to peculiar form of saturating nonlinearity which has a focusing-defocusing nature -- for weak amplitudes being focusing becoming defocusing for higher amplitudes. It is shown that delocalized vortex soliton is stable in entire region of its existence while single- and multi-charged localized vortex solitons are unstable for low amplitudes and become stable for relativistic amplitudes.

description: Livestock farming and especially pig husbandry are controversially discussed in European society. As a result, the demand for higher animal welfare standards is rising. However, higher animal welfare standards imply higher production costs for farmers and other partners along the processing chain. Therefore, farmers are concerned about their future perspective. Since Germany is a net exporter for pork, the question arises, whether German pork produced under higher animal welfare standards might have a chance on foreign markets? Thus, within this study, four case studies for Poland, Italy, Japan and South Korea were selected to assess the possible export potential for German pork produced under higher animal welfare standards. Two survey methods were used: First, a market analysis to generate market information and second, interviews with market experts in all four countries to receive additional insider information regarding the respective pork market. The expert interviews were evaluated based on a qualitative content analysis. According to the interviewees the issue of animal welfare plays a distinct role in each country covered. Particularly large disparities have been observed regarding the attitude towards animal welfare in European and in Asian countries. Besides the aspect of animal welfare further criteria seem to be relevant for consumers. Therefore, purchasing criteria such as quality (in particular meat quality including colour, water capacity, freshness), taste, price and the country of origin have to be considered. These criteria already indicate a possible outcome of our analysis that the export potential of German pork produced under higher animal welfare standards varies depending on the individual target market. Therefore, multiple aspects and market data need to be analysed in order to understand the mechanism and speciality of foreign markets. Nevertheless, further research steps need to be carried out in order to be able to make a clearer statement regarding the export potential of German pork produced under higher animal welfare standards.

description: Structured, periodic optical materials can be used to form photonic crystals capable of dispersing, routing, and trapping light. A similar phenomena in periodic elastic structures can be used to manipulate mechanical vibrations. Here we present the design and experimental realization of strongly coupled optical and mechanical modes in a planar, periodic nanostructure on a silicon chip. 200-Terahertz photons are co-localized with mechanical modes of Gigahertz frequency and 100-femtogram mass. The effective coupling length, which describes the strength of the photon-phonon interaction, is as small as 2.9 microns, which, together with minute oscillator mass, allows all-optical actuation and transduction of nanomechanical motion with near quantum-limited sensitivity. Optomechanical crystals have many potential applications, from RF-over-optical communication to the study of quantum effects in mesoscopic mechanical systems.

Indigenous perspectives to unlearn colonial mindsets : an exploration of oral history and narrative in Homer and Herodotus
Creators: name: Archibald, Kara

description: The study of the past, History, is often presented through a colonial lens. The past is a collection of events that happened, with people who existed, and it can be seen as static and a record of the truth. With the current discourse on decolonization, however, such a representation of history sets a limitation, on classical studies in particular, in the way that the past can be examined. It is the stagnation of imagination that causes a rift between what is considered historical and what is considered fictional. Therefore, it is integral to engage in alternative approaches to the ancient past, and one key way to do this is to Indigenize it. In texts such as the 'Iliad' and the 'Odyssey,' the fictional or mythical elements supersede the significance of orality and oral history. Homer’s epics are therefore considered unverifiable, which can ultimately lead to the limitations of what can be interpreted and gleaned from reading these epic poems. The information and details embedded in the poem, however, are remnants of cultural memory, and are highly influential to later authors, including translators today. Further, Herodotus’ 'Histories' is subject to scrutiny for the validity of his text, whether he wrote the truth as it actually was or whether he invented it. Based on the way historians, both modern and ancient, experience and interpret the past, any form of fictionalization can result in assumptions. Interpretation and translation can often lead to discrepancies in order to make the past look a certain way. In some cases, through a colonial perspective, it means putting emphasis on socially acceptable ideas rather than what might have been the reality. As a result, anything outside of those ideals are considered “unsophisticated.” It is necessary to break away from opposing categorization – black and white, real or fake, true or false – in order to see the complex nature of the past through Indigenous perspectives on its texts. As such, this thesis is an exploration of the significance of orality, oral history, and the use of narrative in order to provide different interpretations of these ancient texts.

description: The productions of thorium and uranium are key ingredients in $r$-process nucleo-cosmochronology. With the combination of improved nuclear and stellar data, we have made detailed investigations on the $r$-process abundance pattern in the very metal-poor halo stars based on the classical $r$-process approach. It is found that the results are almost independent of specified simulations to observed abundances. The influence from nuclear mass uncertainties on Th/U chronometer can approach 2 Gyr. Moreover, the ages of the metal-poor stars HE 1523-0901, CS 31082-001, and BD +17$^\circ$3248 are determined as $11.8\pm 3.7$, $13.5\pm 2.9$, and $10.9 \pm 2.9$ Gyr, respectively. The results can serve as an independent check for age estimate of the universe.

description: Modern coral reefs and associated biodiversity are severely threatened by increasing terrestrial runoff. Similar scenarios could be suspected for geological times, but reef coral resilience is still an enigma. In late Visean-Serpukhovian (Mississippian foraminiferal zones/MFZ 14-16) times, a major glaciation phase of the late Palaeozoic Ice Age (LPIA) associated with enhanced terrestrial weathering and runoff coincides with a biodiversity crisis and coral reef decline. In this study, the impact of enhanced terrestrial runoff is tested on size variations of colonial corals Aulina rotiformis and Lithostrotion decipiens along a gradient of contemporaneous (Serpukhovian) open marine carbonate to nearshore siliciclastic facies in South China. Along this gradient, their sizes decrease from carbonate, through intermediate carbonate-siliciclastic, to siliciclastic facies. This is consistent with increasing abundance of terrestrial materials of high silicon, aluminium, and phosphorus values. On a larger million-year-long interval (MFZ14-16) and for several palaeocontinents, size data of Lithostrotion decipiens and Siphonodendron pauciradiale show a distinct decline in late Visean, when enhanced terrestrial weathering occurred commonly with palaeosols developed during regression. This suggests that terrestrial sediment and nutrient input may have mainly controlled phenotypic plasticity in Mississippian reef corals, with a decrease in size as a component of resilience across the LPIA onset.

description: Bisexual individuals experience higher rates of depression than heterosexual individuals and women experience higher rates of depression than men; however, few studies have quantified the joint effects of sexual orientation and gender. In the 2013–2014 and 2015-2016 National Health and Nutrition Examination Survey, depression symptoms were assessedusing the Patient Health Questionnaire. We used pooled and gender-stratified Poisson regression with robust variances to determine the independent effects of sexual orientation and gender on depression symptoms and calculated relative excess risk due to interaction to examine the joint effects of bisexual orientation and women’s gender on depression symptoms. In adjusted models, depression symptoms were 1.78 times higher in women than in men (99% confidence interval [CI]: 1.776, 1.782), 1.73 times higher in bisexual individuals than in heterosexual individuals (99% CI: 1.726, 1.735), and 3.15 times higher in bisexual women than in heterosexual men (99% CI: 3.145, 3.163). We found evidence for a non-additive model of the excess prevalence of depression symptoms among bisexual women. Gender-specific services addressing the unique mental health needs of bisexual women are needed.
