description: Canadian women, and particular groups of women, are disproportionately burdened by poverty. Social enterprise is a possible solution to unemployment and low income, but little research pertains to women. A collective case study method, with three women-specific social enterprises in three Canadian cities was employed. Data was collected in 2012 from interviews with staff members and participants, site visits, observations and documentation. Results indicate these models train and employ women who have little opportunity. Through a women-informed, intersectional model, services can be customized to respond to the needs of particular populations of women. Women’s chance of success increases when programs provide combinations of soft and hard skill training, followed by employment in an environment that simultaneously offers comprehensive support. Women are thus supported economically by learning important transferable job and life skills, gaining employment experience and earning an income. Socially, women are helped through various support services and through the building of relationships and self esteem. Organizations receive income generated from the business activity, increase their social standing in the community, and contribute to addressing public needs. The creation of social capital is another advantage. Two main challenges were identified. First, women’s social enterprise appears to be consistently under-funded, leaving these organizations in a position where tough financial decisions occur, often at the cost of the social objective, or vice versa. Further, lack of financial resources also restricts the ability of the enterprise to effectively market their business, thus impacting business generation and employment opportunity for women. Second, there is evidence that questions the long-term economic sustainability for women. Due to low wages, inconsistent hours, lack of further training and additional employment opportunities, women are earning little and continue to depend on other financial supports. These difficulties are linked with an under-resourced sector, begging the question: if funding increased, would these challenges be mitigated? Women’s social enterprise is a valuable approach to alleviating women’s unemployment, exclusion and poverty. However, these models requires further subsidy and ongoing support, and need to be part of a wider structural response to these issues, which include involvement from government, community and other social services.

description: Canada has been known as a country that is bilingual when it comes to language policy and multicultural when it comes to cultural diversity. However, while the immigration numbers have been increasing in Canada (Statistics Canada, 2012), newcomers are often seen to be left out of the scope of discussion on languages (Dasko, 2003; Parkin & Turcotte, 2004). In fact, the discourse and research on official bilingualism have largely been shaped by promoting bilingualism only among Anglophone and Francophone communities (Mady, 2008). In this study, I investigated the perceptions, experiences, and practices of 64 adult immigrant students learning one of Canada’s official languages (English or French) with regard to bilingualism in Alberta and Canada. By analyzing survey findings on participants’ perceptions of bilingualism and in-depth open-ended individual and focus-group interviews, I attempted to answer how the promoted official bilingualism and the dominant English reality are reconciled and explained and how immigrants’ voices are placed in the discourses on bilingualism in the monolingual and multicultural environment. Following a critical sociolinguistic framework (Heller, 2006), I argue it is the interplay between official bilingualism and bilingualism as a social practice that characterizes and guides immigrants’ narrations of how they place themselves in discourses of bilingualism. I demonstrate that often a macro-level discourse on official bilingualism maintained and promoted by the government does not correlate with a micro-level discourse produced by new Canadians, and I recommend further consideration of accommodating immigrants’ voices in the official bilingualism discourse.

description: The number of people affected by brain damage each year ranges from millions to billions. Research into factors that affect brain damage and recovery from the disabilities incurred is pertinent to alleviating stress put on individuals, their families, healthcare systems, and society as a whole. Circadian rhythms are ubiquitous throughout the animal kingdom, throughout individual organisms, and even in each cell of an organism. Therefore, circadian influences on brain damage, recovery, and physical brain repair warrant further investigation. In this dissertation, the role of the circadian clock in stroke outcome, and in models of brain repair will be examined. I hypothesize that circadian rhythmicity is involved not only in outcomes following brain damage, but may also be a significant contributor to neuroregeneration. Here, I show the effects of the time of day that a stroke occurs on behavioural and anatomical outcome in rats. This is followed by an investigation into the rhythmic expression of clock genes in regenerated medial prefrontal cortex (MPFC), and the effects that circadian dysfunction has on regeneration in both the neonatal MPFC, and adult subgranular zone of the dentate gyrus in mice.

description: GW/P bodies (GWB) are cytoplasmic foci that contain GW182 and Ago2 that bind micro RNA (miRNA) within the RNA-induced silencing complex (RISC) to silence and degrade messenger RNA (mRNA). Clinical studies indicate that 33% of patients with GWB autoantibodies have a motor/sensory neuropathy and/or ataxia. Preliminary data show that GWB are highly expressed in the central nervous system, particularly in astrocytes. Characterizing the protein and RNA components of GWB is key to elucidating their function in astrocyte and astrocytoma cells. First, a detailed immunoprecipiation (IP)-Western blot (WB) protocol was developed to addresses challenges in isolating low abundance protein GW182 and GWB-associated proteins. This protocol provides a biochemical approach for detecting GW182 and associated proteins in biological samples facilitating the elucidation of the diverse functions of GWB. Second, astrocytoma GWB exhibit complex heterogeneity with combinations of LSm4 and XRN1 as well as Ago2 and Dicer, key proteins involved in mRNA degradation and RNA interference respectively. GWB subsets contained the mRNA transport and stabilization proteins SYNCRIP, hnRNPA1 and FMRP, not previously described as part of the GWB complex. Astrocytoma GWB-IP suggested that Dicer, hDcp, LSm4, XRN1, SYNCRIP and FMRP form a multiprotein complex and are involved in a number of regulatory mRNA pathways. Third, GWB/RISC mRNA and miRNA components were profiled by microarray analysis of astrocytoma cells and astrocytes. MiRNAs were highly enriched in astrocyte RISC compared to astrocytoma RISC, astrocytoma and astrocyte cells each contained unique RISC miRNA profiles as compared to their respective cellular miRNA profiles, miR-195, 10b, 29b, 19b, 34a and 455-3p levels were increased and the miR-181b level was decreased in astrocytoma RISC as compared to astrocyte RISC, and the RISC contained decreased levels of mRNAs in astrocyte and astrocytoma cells. Biological pathway analysis of RISC mRNA suggests that ultimately GWB play a pivotal role in malignancy. In future, it is important to move beyond characterizing the GWB components of resting cells, but determine the functional response of GWB when subjected to physiologically relevant stimuli. Clinically, there is much to learn about other GWB autoantigens, other diseases associated with GWB autoantibodies and the genetic basis for GWB autoimmunity.

description: (Abridged) The rest-frame near-IR spectra of intermediate age (1-2 Gyr) stellar populations are dominated by carbon based absorption features offering a wealth of information. Yet, spectral libraries that include the near-IR wavelength range do not sample a sufficiently broad range of ages and metallicities to allow for accurate calibration of stellar population models and thus the interpretation of the observations. In this paper we investigate the integrated J- and H-band spectra of six intermediate age (1-3 Gyr) and old (>10 Gyr) globular clusters in the Large Magellanic Cloud, using observations obtained with the SINFONI IFU at the VLT. H-band C2 and K-band 12CO(2-0) feature strengths are compared to the models of Maraston (2005). C2 is reasonably well reproduced by the models at all ages, while 12CO(2-0) shows good agreement for older (age>2 Gyr) populations, but the younger (1.3 Gyr) globular clusters do not follow the models. We argue that this is due to the fact that the empirical calibration of the models relies on only a few Milky Way carbon star spectra, which show different 12CO(2-0) index strengths than the LMC stars. The C2 absorption feature strength correlates strongly with age. It is present essentially only in populations that have 1-2 Gyr old stars, while its value is consistent with zero for older populations. The distinct spectral energy distribution observed for the intermediate age globular clusters in the J- and H-bands agrees well with the model predictions of Maraston for the contribution from the thermally pulsing asymptotic giant branch phase (TP-AGB). We show that the H-band C2 absorption feature and the J-, H-band spectral shape can be used as an age indicator for intermediate age stellar populations in integrated spectra of star clusters and galaxies.

Statistical tests for the intersection of independent lists of genes: Sensitivity, FDR, and type I error control

description: Public data repositories have enabled researchers to compare results across multiple genomic studies in order to replicate findings. A common approach is to first rank genes according to an hypothesis of interest within each study. Then, lists of the top-ranked genes within each study are compared across studies. Genes recaptured as highly ranked (usually above some threshold) in multiple studies are considered to be significant. However, this comparison strategy often remains informal, in that type I error and false discovery rate (FDR) are usually uncontrolled. In this paper, we formalize an inferential strategy for this kind of list-intersection discovery test. We show how to compute a $p$-value associated with a "recaptured" set of genes, using a closed-form Poisson approximation to the distribution of the size of the recaptured set. We investigate operating characteristics of the test as a function of the total number of studies considered, the rank threshold within each study, and the number of studies within which a gene must be recaptured to be declared significant. We investigate the trade off between FDR control and expected sensitivity (the expected proportion of true-positive genes identified as significant). We give practical guidance on how to design a bioinformatic list-intersection study with maximal expected sensitivity and prespecified control of type I error (at the set level) and false discovery rate (at the gene level). We show how optimal choice of parameters may depend on particular alternative hypothesis which might hold. We illustrate our methods using prostate cancer gene-expression datasets from the curated Oncomine database, and discuss the effects of dependence between genes on the test.

description: Background Obesity can be a signifcant challenge to health and quality of life (QoL). Bariatric surgery assists with weight loss and may help improve QoL. However, not all patients beneft from surgery. Personality traits may be related to QoL outcomes after bariatric surgery, but these associations are unclear. Purpose This research reviews the published literature on the associations between personality and QoL among post‐operative bariatric patients. Method Four databases (CINAHL Complete, Medline with Full Text, APA PsycINFO, and Scopus) were searched from inception until March 2022. Forward searching was conducted using Google Scholar, and backward reference citation searches were also performed. Results Five studies met inclusion criteria yielding data from N=441 post-bariatric patients including both pre/post and cross-sectional designs. Higher agreeableness was related to lower overall health-related QoL (HRQol) and gastric HRQol and positively associated with psychological HRQol. Higher emotional stability was positively related to overall HRQol. Higher impulsivity was negatively associated with mental HRQol and was unrelated to physical HRQol. Efects for the remaining traits were either mainly mixed or null. Conclusion Personality traits may be associated with HRQol outcomes. However, it is difcult to reliably discern the role of personality traits for HRQol and QoL outcomes given the methodological issues and few published studies. More rigorous research is needed to address these issues and clarify possible associations.
Effect of Cannabinoids and Stress on Motor Maps and Behaviour

description: Motor maps exhibit experience dependent changes and are therefore sensitive to the type and amount of neurotransmitters present in the motor cortex and changes in motor map expression often results in impairments of skilled behaviour. Endocannabinoids have been shown to affect spinal locomotion and stress has been shown to affect spontaneous locomotion therefore, the effect of cannabinoid signaling and stress on motor map expression and behaviour was examined. The first study determined that cannabinoid 1 receptor (CB1R) signaling dampened motor map expression and that both anandamide (AEA) and 2-arachidonoylglycerol (2-AG) contributed to this effect. Activation of CB1R signaling did not affect skilled reaching task performance. However, a lack of cannabinoid signaling resulted in impairment on performing the reaching motion. The second study characterized acute and repeated stress effects on motor map expression. Acute stress did not alter map expression while repeated stress decreased forelimb map expression and resulted in skilled motor behaviour deficits. It was then established that 2-AG mediates the stress effects seen on motor map expression. The last study observed the effects of delta-9-tetrahydrocannabinol (THC) on motor map expression as well as skilled and unskilled behaviour. It was discovered that THC dose dependently affected motor map expression in that a low dose of THC increased map expression while higher doses decreased forelimb map expression. THC decreased the number of reach attempts made in one 15 minute reach training session but did not impair the execution of reaching behaviour. Unskilled behaviour was assessed using the bar task, rotorod, horizontal ladder rung walking task and the open field test. No differences were found between rats that received THC and rats that received DMSO on the rotorod, rung walking task and the open field test. The highest dose of THC used (2.5 mg/kg) resulted in a longer latency for removal of the forepaws from the bar in the bar task. This research is important and necessary due to increasing usage of cannabinoids for recreation as well as to treat neurological illness. The present findings suggest that endocannabinoids and repeated stress via 2-AG have a dampening effect on motor map expression.

description: Waterflooding in heavy oil reservoirs has an almost 50 years history in western Canada, but its recovery mechanisms, especially in the situation of a high oil to water viscosity ratio, are still not well understood. This thesis studied the water imbibition mechanisms in the process of heavy oil waterflooding, and their effects on oil recovery using a glass made micromodel. In a water-wet environment, waterflooding (water displacing oil) represents a process of water imbibition. This water imbibition experimental study was conducted with varying water injection rates and oil viscosities. The effects of time, viscosity ratio and water injection rate on imbibition rate were studied. The recovery factor was proportional to the square root of time, and it also had a definite relationship with oil viscosity even though it was not linear. The effects of injection rate on imbibition rate were complicated. Images of the imbibition process were recorded and analyzed. Water broke through quickly because of water fingering. A significant amount of oil was produced during the post-breakthrough period under high water cuts. In the cases of low rate water injection, water imbibed into the original oil region perpendicularly to the water channel. At this stage, capillary forces were the key factor. Water film thickening, snap-off and oil refilling were the main mechanisms that made water imbibition work. Emulsification was also another important mechanism observed, with W/O emulsions primarily being formed.

description: I review constraints on the physical properties of AGN jets revealed through Very Long Baseline Interferometry (VLBI) studies of the structure and time-evolution of parsec-scale jets, including recent results from the MOJAVE program. In particular I focus on constraints available from very long time baseline studies which probe a wide range of jet behavior over many outbursts. Kinematic studies of propagating jet features find an apparent speed distribution that peaks around 10c for blazars, with speeds up to 50c observed. These observed speeds require Lorentz factors at least as large, implying that parsec-scale Lorentz factors up to 10-20 are common for blazars with a tail up to ~ 50. Jet flows are still becoming organized on these scales as evidenced by the high incidence of non-radial motions and/or accelerations of jet features (including increases and decreases in apparent speed and direction). Changes in Lorentz factors of propagating jet features appear to play a significant role in the observed accelerations, and while the connection between acceleration of jet features and the underlying flow is not clear, the pattern of observed accelerations suggest the flow may increase in speed near the base of the jet and decrease further out. In some jets, ejections of new features span a range of ejection angles over many epochs, tracing out wider opening angles on parsec-scales than are apparent in single epoch observations.

description: We forecast the ability of future CMB and galaxy lensing surveys to constrain variations of the fine structure constant. We found that lensing data, as those expected from satellite experiments as Euclid could improve the constraint from future CMB experiments leading to a Δα/ α= 8*10^{-4} accuracy. A variation of the fine structure constant αis strongly degenerate with the Hubble constant H_0 and with inflationary parameters as the scalar spectral index n_s. These degeneracies may cause significant biases in the determination of cosmological parameters if a variation in αas large as \sim 0.5 % is present at the epoch of recombination.

description: There is a difference between the science done and reported in grade-school science classes and that done by scientists conducting research. Participants generally conceptualize the two types of engagement as distinct projects. Grounding in complexity and network theory reveals connections to communities of practice and collaboratories which exist within the environment of professional scientists, but which are lacking from typical grade-school science practices. The lens of Integral Theory reveals that the two realms are further separated in their relative strengths, weaknesses and foci. Combining these facets prompted this exploration of using a sharing conference as a vehicle for building a collaborative community of practice involving both scientists and grade-school students. The research involved creating a community of practice involving scientists and grade-school students that culminated in a school conference and a research paper. Using a framework of Educational Design Research informed by Integral Research principles, information about three main questions was sought: (1) How is it possible to encourage students to participate actively in a community of scientists through the development of a school conference on science? (2) In what ways might this model a direction worthy of inclusion within the evolving science education paradigm? (3) How might engaged participation in a complex community of scientific practice provide benefit to students’ discourse (and participation) as scientists? Data were gathered using mixed methods and presented here as provocative and illustrative case studies that compel and support theory generation. The ultimate purposes were theory generation and the discovery of enhanced meaning of the situation. The lenses of complexity, Integral Theory and network theory were applied to provide context to events as they occurred in a situated fashion. It was observed and reported that the creation of a complex learning environment focused on the research and reporting of a topic in science to be presented at a school conference provided significant motivation and growth opportunities for students and teachers alike. Key elements that contribute to these growths are proposed as are discussions of evolutionary tensions and aspects that could enhance the application of the project for future use.

description: This work deals with chaotic quantum dot connected to two and four leads. We use standard diagrammatic procedure to integrate on the unitary group, to study the main term in the semiclassical expansion of the noise in the three pure Wigner-Dyson ensembles at finite frequency and temperature, in the noninteracting and interacting regimes. We investigate several limits, related to the temperature and the potential difference in the leads, in the presence of a capacitive environment. At the thermal crossover regime, we obtain general expressions described in terms of parameters that can be controlled experimentally. As an interesting result, we show the appearance of asymmetries in the noise, controlled by the topology of the cavity and the number of open channels in the corresponding terminals.

description: We present a general framework for systems which are prepared in a non-stationary non-equilibrium state in the absence of any perturbation, and which are then further driven through the application of a time-dependent perturbation. We distinguish two different situations depending on the way the non-equilibrium state is prepared, either it is created by some driving; or it results from a relaxation following some initial non-stationary conditions. Our approach is based on a recent generalization of the Hatano-Sasa relation for non-stationary probability distributions. We also investigate whether a form of second law holds for separate parts of the entropy production, in a way similar to the work of M. Esposito et al., Phys. Rev. Lett., 104:090601 (2010), but for a non-stationary reference process instead of a stationary one. We find that although the special structure of the theorems derived in this reference is not recovered in the general case, detailed fluctuation theorems still hold separately for parts of the entropy production in this case. These detailed fluctuation theorems lead to interesting generalizations of the second-law of thermodynamics off equilibrium.

description: Modulating the activity of ion channels by blockers yields information on both the mode of drug action and on the biophysics of ion transport. Here we investigate the interplay between ions in the selectivity filter (SF) of K⁺ channels and the release kinetics of the blocker tetrapropylammonium in the model channel KcvNTS. A quantitative expression calculates blocker release rate constants directly from voltage-dependent ion occupation probabilities in the SF. The latter are obtained by a kinetic model of single-channel currents recorded in the absence of the blocker. The resulting model contains only two adjustable parameters of ion-blocker interaction and holds for both symmetric and asymmetric ionic conditions. This data-derived model is corroborated by 3D reference interaction site model (3D RISM) calculations on several model systems, which show that the K⁺ occupation probability is unaffected by the blocker, a direct consequence of the strength of the ion-carbonyl attraction in the SF, independent of the specific protein background. Hence, KcvNTS channel blocker release kinetics can be reduced to a small number of system-specific parameters. The pore-independent asymmetric interplay between K⁺ and blocker ions potentially allows for generalizing these results to similar potassium channels.

description: This case study presents a firsthand account of the long-term emotional, cognitive, and functional effects of untreated adult ADHD compounded by Rejection Sensitive Dysphoria (RSD). Through a qualitative, autobiographical narrative, the author--a U.S. Navy veteran--offers clinically relevant insights into the internal experience of emotional dysregulation, trauma responses, and relational breakdowns. Key findings include consistent emotional collapse during conflict, chronic functional impairment, and the link between emotional neglect and trauma-triggered RSD episodes. The study proposes that RSD should be considered a core diagnostic and treatment factor in adult ADHD and underscores the need for trauma-informed, emotion-centered diagnostic protocols. The paper contributes to the field of Emotion Science and Clinical Psychology by presenting a lived-experience case that bridges clinical gaps and affirms the diagnostic validity of emotional symptoms within ADHD.

description: The world is increasingly dependent on cyber-physical systems (CPSs), e.g., robotic vehicles (RVs) and industrial control systems (ICSs). CPSs operate autonomously by processing data coming from both “cyberspace”—such as user commands—and “physical space”—such as sensors that measure the physical environment in which they operate. However, even after decades of research, CPSs remain susceptible to threats from attackers, primarily due to the increased complexity created by interaction with cyber and physical space (e.g., the cascading effects that changes in one space can impact on the other). In particular, the complexity causes two primary threats that increase the risk of causing physical damage to RVs: (1) logic bugs causing undesired physical behavior from the developers expectations; and (2) physical sensor attacks—such as GPS or acoustic noise spoofing—that disturb an RV’s sensor readings. Dealing with these threats requires addressing the interplay between cyber and physical space. In this dissertation, we systematically analyze the interplay between cyber and physical space, thereby tackling security problems created by such complexity. We present novel algorithms to detect logic bugs (PGFuzz in Chapter 2), help developers fix them (PGPatch in Chapter 3), and test the correctness of the patches attempting to address them (PatchVerif in Chapter 4). Further, we explain algorithms to discover the root causes and formulate countermeasures against physical sensor attacks that target RVs in Chapter 5.

However, traditional textual classifiers usually rely on many hand-crafted features and do not produce satisfying results. We introduce a relatively deep residual neural network for Web page classification problem based on the simplified version of the target HTML document. Combining several advanced techniques of deep learning, the optimal model has 20 neural layers with parameters, and is end-to-end differentiable. We also present a top RNN classifier to utilize the class information from the relatives Web pages. Two large-scale datasets are constructed to show that our ResNet-20 and top RNN design could achieve best or promising results, compared to several baseline methods.

description: Nurses who work in critical care face a unique array of ethical decisions in the course of their practice. This study aimed to examine the source of the ethical decision making of individual nurses using a virtue ethics framework as a starting point. The design used a philosophical hermeneutic approach based on the writing of Paul Ricoeur to provide an interpretation of the ethical decision making process of nurses. Six nurses currently practicing in intensive care were interviewed, with the transcripts of the interviews used as texts which were analyzed using the concepts of distanciation and appropriation taken from Ricoeur. The results revealed the main themes of time, experience, and communication, which were related to self-identity as the basis of ethical decision making

description: Automated answering of natural language questions is an interesting and useful problem to solve. Question answering (QA) systems often perform information retrieval at an initial stage. Information retrieval (IR) performance, provided by engines such as Lucene, places a bound on overall system performance. For example, no answer bearing documents are retrieved at low ranks for almost 40% of questions. In this paper, answer texts from previous QA evaluations held as part of the Text REtrieval Conferences (TREC) are paired with queries and analysed in an attempt to identify performance-enhancing words. These words are then used to evaluate the performance of a query expansion method. Data driven extension words were found to help in over 70% of difficult questions. These words can be used to improve and evaluate query expansion methods. Simple blind relevance feedback (RF) was correctly predicted as unlikely to help overall performance, and an possible explanation is provided for its low value in IR for QA.
Distribution of velocity gradients and rate of caustic formation in turbulent aerosols at finite Kubo numbers

description: In a one-dimensional model for a turbulent aerosol (inertial particles suspended in a random flow) we compute the distributions of particle-velocity gradients and the rate of caustic formation at finite but small Kubo numbers Ku, for arbitrary Stokes numbers St. Our results are consistent with those obtained earlier in the limit of small Ku and and large St, such that Ku^2 St remains constant. We show how finite-time correlations and non-ergodic effects influence the inertial-particle dynamics at finite but small Kubo numbers.

description: The output of renewable energy fluctuates significantly depending on weather conditions. We develop a unit commitment model to analyze requirements of the forecast output and its error for renewable energies. Our model obtains the time series for the operational state of thermal power plants that would maximize the profits of an electric power utility by taking into account both the forecast of output its error for renewable energies and the demand response of consumers. We consider a power system consisting of thermal power plants, photovoltaic systems (PV), and wind farms and analyze the effect of the forecast error on the operation cost and reserves. We confirm that the operation cost was increases with the forecast error. The effect of a sudden decrease in wind power is also analyzed. More thermal power plants need to be operated to generate power to absorb this sudden decrease in wind power. The increase in the number of operating thermal power plants within a short period does not affect the total operation cost significantly; however the substitution of thermal power plants by wind farms or PV systems is not expected to be very high. Finally, the effects of the demand response in the case of a sudden decrease in wind power are analyzed. We confirm that the number of operating thermal power plants is reduced by the demand response. A power utility has to continue thermal power plants for ensuring supply-demand balance; some of these plants can be decommissioned after installing a large number of wind farms or PV systems, if the demand response is applied using an appropriate price structure.

description: In order to obtain quite precise information about the shape of the particle paths below small-amplitude gravity waves travelling on irrotational deep water, analytic solutions of the nonlinear differential equation system describing the particle motion are provided. All these solutions are not closed curves. Some particle trajectories are peakon-like, others can be expressed with the aid of the Jacobi elliptic functions or with the aid of the hyperelliptic functions. Remarks on the stagnation points of the small-amplitude irrotational deep-water waves are also made.

description: Animals with restricted dispersal, like the Ord’s kangaroo rat (Dipodomys ordii), are sensitive to habitat loss and fragmentation. I researched two conservation tools that have the potential to help stabilize the Alberta kangaroo rat population: stepping stones and translocations. Using survey data and habitat mapping, I determined that many inter- dune distances in Alberta exceed the estimated dispersal ability of most kangaroo rats. I developed an algorithm to locate potential stepping stone locations to restore connectivity and prioritized them based on their contribution to the network functional connectivity. I then evaluated if translocations could be used in place of natural dispersal to increase rescue and recolonization of isolated habitats. My findings indicate that (1) four strategically placed stepping stones will positively impact the functional connectivity of the dune network, and (2) translocations can lead to successful site establishment, with evidence of occupancy observed in seven of the sixteen translocations.
