Democratizing work
Creators: name: Castle, Albert A.
Publisher: name: No Publisher Supplied
Year: 2019

description: Rights won by workers through mass mobilization and collective bargaining, even when extensive, normally stop short of significant worker ownership or control of the firm. Worker cooperatives – businesses owned and controlled by their worker members – can, in theory, offer a radical organizational, legal, and ideological alternative to the hierarchical governance and worker dispossession characteristic of the modern firm. Yet whereas some ethnographic research has shown that worker cooperatives can preserve democratic control and accountability in the face of competitive pressures and corporatization, a number of studies have suggested just the opposite, finding that many worker members report feeling distant from the management of their cooperative and alienated from their work. Moreover, some observers argue that contrary to the assumption that cooperative workplaces should foster solidaristic and anti-capitalistic values, they can in fact promote individualism and a petit-bourgeois sensibility, and weaken labor solidarity. In-depth, semi-structured interviews with 32 members at a dozen worker cooperatives throughout England show that the British worker cooperative movement has cultivated a participatory, communitarian, and egalitarian legal consciousness and workplace culture that is undergirded by the institutionalization of democratic governance, common property, and equal wages. However, members feared that a lack of social support, combined with pressures to grow in order to compete with large and international firms, could compel their cooperative to compromise principles, lower standards, and lose their character. Analysis of the history of the British cooperative movement and evaluations of cooperatives by foundational political economists underline worker cooperatives’ enduring importance to – yet persistent marginality within – working class politics and socialist theory. By merging labor and capital rather than attempting to equalize them, and by socializing capital chiefly at the level of the enterprise rather than the state, worker cooperatives have appeared to work at cross-purposes with broader labor and leftist movements. Worker cooperatives however offer a tried-and-tested model of workplace democracy and economic equality that depends on the success of those movements for their own.

description: Different imaging modes of low temperature laser scanning microscopy (LTLSM) have been applied to probe local optical and superconducting properties, as well as the spatial variations in thermoelectric and electronic (both dc and rf) transport, in a YBa_2Cu_3O_6.95 /LaAlO_3 (YBCO/LAO) superconducting microstrip resonator with micron-range resolution. Additionally, the local sources of microwave nonlinearity (NL) were mapped in two-dimensions simultaneously by using the LTLSM in two-tone rf intermodulation distortion contrast mode as a function of (x,y) position of the laser beam perturbation on the sample. The influence of the direction of individual twin-domain YBCO blocks on its NL properties was analyzed in detail. The result shows the direct spatial correlation between NL microwave and dc electronic transport properties of the YBCO film that are imposed by the underlying twin-domain topology of the LAO substrate. In these circumstances, the scale of local NL current densities J_IM(x,y) in different areas of the YBCO microstrip quantitatively coincide with the scale of local critical current densities J_c(x,y) measured at the same positions.

Publisher: name: Zenodo
Year: 2014

description: The aim of this study was to evaluate the efficacy of insulin pump administration in improving glycemic control in patients with Type 1 diabetes compared to management via multiple daily insulin injections (MDI). HgbA1c level was identified as the outcome measure of glycemic control. Patients were identified by the researcher via an electronic database of patients on insulin pump and MDI therapy who met the inclusion criteria. All patients with odd numbers assigned to them were selected for inclusion in this study. Thirty subjects on insulin pumps and 30 on MDI were selected for participation. Data were collected via chart review using a data collection tool developed by the researcher to collect information on the subjects’ age, gender, ethnicity, and age of onset of diabetes. HgbA1c level, body mass index (BMI) and total daily dose of insulin were also collected at baseline, as well as 3, 6, 12, and 24 months post insulin therapy. The baseline and post insulin therapy at 3, 6, 12, and 24 months allowed the researcher to evaluate the efficacy of insulin pump in improving glycemic control as compared to MDI. There was no statistically significantly difference between the two groups for age, gender, ethnicity, BMI, HgbA1c and total daily insulin doses. Several conclusions were reached. It was found that insulin pump and MDI have similar effects on glycemic control over a 24-month period of time. Further research of larger and more heterogeneous samples would be likely provide a better assessment of the efficacy of insulin pump therapy in comparison to MDI therapy.

The occupational structure of Spain, 1877-1981
Creators: name: Mora-Sitja, Natalia
Publisher: name: Apollo - University of Cambridge Repository
Year: 2020

description: FIRST PARAGRAPH Spain’s long-run economic growth trajectory in the past two centuries has had major setbacks. Spain fell behind Europe in GDP per capita growth in the nineteenth century, lost even more ground in the interwar period despite being non belligerent in the World Wars, and only managed to catch up in the second half of the twentieth century.1 Historians mostly agree on this assessment, but there is less consensus on the extent and nature of Spanish economic development in the nineteenth and early twentieth centuries. The traditional view was a pessimistic one: led by Nadal’s seminal book on the failure of the industrial revolution in Spain the economic history of Spain written in the 1970s emphasised the absence of intensive economic growth in nineteenth-century Spain, with the exception of some regional industries – textiles in Catalonia, and iron and steel in the Basque Country – which nonetheless had their growth potential curtailed by the backwardness of the agrarian sector and the accompanying lack of domestic consumer demand for manufactured goods. In the 1980s Prados de la Escosura’s reconstruction of macroeconomic series and national accounts led the revisionist, and more optimistic view, with an upward revision of estimates of GDP per capita growth in the nineteenth century and, more importantly, of agricultural productivity.
Development of a fast and efficient liposomal drug loading technology for poorly water soluble drugs : formulation, characterization, and potential applications
Creators: name: Tang, Wei-Lun
Publisher: name: University of British Columbia
Year: 2018

description: More than 70% of drugs exhibit poor water solubility, thereby limiting their clinical applications. Formulating these drugs into liposomes is a feasible approach to increase their solubility and improve the therapeutic efficacy. However, encapsulating hydrophobic drugs into the lipid bilayer of liposomes often results in burst drug release and liposomal instability, due to the weak association between the drugs and the lipid bilayer. Additionally, the capacity of the lipid bilayer is limited, leading to inefficient drug loading. To address this issue, this thesis focused on developing a new loading technology, called Solvent-assisted Active Loading Technology (SALT), to allow stable and efficient loading of poorly water-soluble drugs into the aqueous core of liposomes. This technology involved the addition of a certain amount of a water-miscible organic solvent into the mixture of a poorly soluble drug and preformed liposomes incorporated with a trapping agent inside the aqueous core. The solvent was not only used to help drug dissolution, but also to facilitate drug permeation into the liposomal core to form drug complexes with the trapping agent by increasing the membrane permeability during the drug loading. We have generated multiple examples to demonstrate the robustness and potential utilities of this technology. As a proof-of-principle, the first part of the thesis focused on developing the SALT for stable loading of a model drug, staurosporine (STS, insoluble weakly basic drug), into liposomes and optimizing the fabrication of a liposomal STS formulation for in vivo therapy of tumor. The second part of this dissertation was to explore whether the SALT is a flexible platform for formulating other types of poorly soluble drugs such as gambogic acid (GA, insoluble weakly acidic drug) into liposomes. We also examined whether other miscible solvents (other than DMSO) could be utilized in the system and their roles in promoting drug loading. The third part of this thesis was to demonstrate another utility of the SALT for preparing an oral pediatric formulation of mefloquine with bitterness masking. This thesis work demonstrated that SALT was a robust drug loading technology to develop stable liposomal formulations for poorly soluble drugs with practical utilities.

description: Regenerating codes are a class of recently developed codes for distributed storage that, like Reed-Solomon codes, permit data recovery from any subset of k nodes within the n-node network. However, regenerating codes possess in addition, the ability to repair a failed node by connecting to an arbitrary subset of d nodes. It has been shown that for the case of functional-repair, there is a tradeoff between the amount of data stored per node and the bandwidth required to repair a failed node. A special case of functional-repair is exact-repair where the replacement node is required to store data identical to that in the failed node. Exact-repair is of interest as it greatly simplifies system implementation. The first result of the paper is an explicit, exact-repair code for the point on the storage-bandwidth tradeoff corresponding to the minimum possible repair bandwidth, for the case when d=n-1. This code has a particularly simple graphical description and most interestingly, has the ability to carry out exact-repair through mere transfer of data and without any need to perform arithmetic operations. Hence the term `repair-by-transfer'. The second result of this paper shows that the interior points on the storage-bandwidth tradeoff cannot be achieved under exact-repair, thus pointing to the existence of a separate tradeoff under exact-repair. Specifically, we identify a set of scenarios, termed `helper node pooling', and show that it is the necessity to satisfy such scenarios that over-constrains the system.

SCHOOL NURSES AND CARE COORDINATION FOR CHILDREN WITH COMPLEX NEEDS: AN INTEGRATIVE REVIEW
Creators: name: McClanahan, Rachel
Publisher: name: Zenodo
Year: 2014

description: Health care for students with chronic needs can be complex and specialized resulting in fragmentation, duplication, and inefficiencies. Students who miss school due to chronic conditions lose valuable educational exposure that contributes to academic success. As health-related disabilities increase in prevalence so does the need for the coordination of care within the school and between the school and service providing agencies. This integrative literature review provides a synthesis of published evidence identifying and describing the core concepts associated with the role of school nurses in providing care coordination to students with complex needs. Six core essentials of nurse provided care coordination were identified: collaboration, communication, care planning and the nursing process, coordination, clinical expertise, and reinforcing components. Recommendations for improving care coordination were elucidated in the review. Analysis of the literature can help assure application of best practice methods for the coordination of care for students in the school setting.

ANESTHESIA PRACTICE GUIDELINES FOR PATIENTS UNDERGOING ENDOSCOPIC RETROGRADE CHOLANGIOPANCREATOGRAPHY
Creators: name: Mendez, Erin M
Publisher: name: Zenodo
Year: 2014

description: Endoscopic retrograde cholangiopancreatography (ERCP) is a common procedure used to diagnose and treat disorders of the biliary and pancreatic ductal systems. The number of procedures performed annually is rising. Endoscopists are challenged with determining the optimal sedation/anesthesia technique for each patient. ERCPs can be performed under conscious sedation, deep sedation, or general anesthesia. The choice of technique is based on the patient’s health status and patient/provider preference. An extensive literature review and expert consultation uncovered numerous safety concerns and complications encountered during ERCPs. In addition, several recommendations were found that have the potential to prevent adverse events, enhance patient safety, and improve efficiency.

description: Environmental impacts of traditional pig production using local breeds are poorly documented. Most studies do not include in their perimeters emissions associated with grazing (EGr) or acorn consumption, or potential carbon sequestration in soils (SeqC). The aim of the present study was to estimate through Life Cycle Assessment (LCA) impacts of traditional pig production in Europe according to four perimeters: Std (standard perimeter), Std + EGr, Std + SeqC, Std + EGr + SeqC. Forty-eight on-farm surveys were conducted in the framework of the TREASURE project (www.treasure.kis.si) to collect the data needed: 25 farms in France (raising Gascon pigs: GAS), 8 farms in Italy (Mora romagnola pigs: MOR), and 15 farms in Slovenia (Krškopolje pigs: KRS). In Std, the climate change (CC) impact per kg live weight at farm gate was lower in KRS than in MOR and GAS (5.85, 7.45 and 7.48 kg CO2-eq, respectively) due to lower environmental impacts of feeds (including co-products obtained on farm) and a better feed conversion ratio of pigs raised indoors. Impacts per ha of land use were lower on GAS farms due to a larger grazing area allocated to the outdoor pigs. In the perimeter Std + SeqC, CC decreased on average by 4%. In the perimeter Std + EGr, CC increased on average by 2%. EGr and SeqC contributed little to the impacts or the reduction in impacts. Hotspots to reduce environmental impacts of traditional pig production include feed composition, decreasing feed distribution to grazing animals, and the origin of feed ingredients.

Identifying and characterizing the spatial variability of supraglacial hydrological features on the western Greenland Ice Sheet
Creators: name: King, Leonora Adele
Publisher: name: University of British Columbia
Year: 2018

description: Glacier and ice sheet response to climate change is modulated in part by the temporal and spatial delivery of surface water to the subglacial system which can enhance ice sliding. Surface-to-bed connections are formed by near-vertical pathways through the ice called moulins. The mechanisms through which moulins form and the hydrological implications of their distribution are inadequately constrained. This thesis focuses on the southwest Greenland Ice Sheet, where surface melt and related features are abundant and where meltwater drainage through moulins has been empirically linked to ice speedup. In the first part, I employ flow routing over a high resolution digital elevation model to delineate supraglacial channels and catchments. I compare my results to an independent dataset and demonstrate that flow routing is an effective tool for delineating channels in high detail. Whereas multispectral methods provide instantaneous discharge estimates and flow routing derived catchments can be used to build hourly hydrographs, the two methods are temporally incongruous and produce discharge estimates in small catchments that differ by several orders of magnitude. In the second part of the thesis, I contribute empirical insight into where moulins form and the hydrological implications of the resultant spatial organization of catchments. Using remotely sensed data on supraglacial lake distribution, bed elevation, ice thickness, surface velocity and strain rate, I show that moulins form predominantly in low velocity, high strain rate ice with adverse bed slopes. Moulins formed near moulin-drained lakes are typically located down-ice of the lake. The spatial distribution of moulins affects the physical characteristics of supraglacial catchments, including elevation, size, elongation, drainage network configuration and slope. This in turn impacts the temporal delivery of meltwater to the subglacial network. I use synthetic unit hydrograph theory based on catchment morphometrics to show that catchment diurnal hydrograph lag times in the study area vary by up to 11 hours. The hydrological implications of subglacial meltwater supply vary according to the configuration of the subglacial catchments, which vary temporally based on subglacial water pressure. Considering this additional level of complexity is a necessary next step in constraining the relationship between melt and ice flow dynamics.

description: Directional detection of non-baryonic Dark Matter is a promising search strategy for discriminating WIMP events from background. However, this strategy requires both a precise measurement of the energy down to a few keV and 3D reconstruction of tracks down to a few mm. To achieve this goal, the MIMAC project has been developed. It is based on a gaseous micro-TPC matrix, filled with CF4 and CHF3. The first results on low energy nuclear recoils (H, F) obtained with a low mono-energetic neutron field are presented. The discovery potential of this search strategy is discussed and illustrated by a realistic case accessible to MIMAC.

description: High quality electron-doped HTSC single crystals of $\rm Pr_{2-x}Ce_{x}CuO_{4+δ}$ and $\rm Nd_{2-x}Ce_{x}CuO_{4+δ}$ have been successfully grown by the container-free traveling solvent floating zone technique. The optimally doped $\rm Pr_{2-x}Ce_{x}CuO_{4+δ}$ and $\rm Nd_{2-x}Ce_{x}CuO_{4+δ}$ crystals have transition temperatures $T_{\rm c}$ of $25$\,K and $23.5$\,K, respectively, with a transition width of less than $1$\,K. We found a strong dependence of the optimal growth parameters on the Ce content $x$. We discuss the optimization of the post-growth annealing treatment of the samples, the doping extension of the superconducting dome for both compounds as well as the role of excess oxygen. The absolute oxygen content of the as-grown crystals is determined from thermogravimetric experiments and is found to be $\ge 4.0$. This oxygen surplus is nearly completely removed by a post-growth annealing treatment. The reduction process is reversible as demonstrated by magnetization measurements. In as-grown samples the excess oxygen resides on the apical site O(3). This apical oxygen has nearly no doping effect, but rather influences the evolution of superconductivity by inducing additional disorder in the CuO$_{2}$ layers. The very high crystal quality of $\rm Nd_{2-x}Ce_{x}CuO_{4+δ}$ is particularly manifest in magnetic quantum oscillations observed on several samples at different doping levels. They provide a unique opportunity of studying the Fermi surface and its dependence on the carrier concentration in the bulk of the crystals.

description: Recent work by Chernodub and Ilgenfritz has uncovered non-trivial temperature dependence in the electric-magnetic asymmetry in the dimension 2 condensate. This asymmetry measures the difference between the spatial and the temporal components of the condensate. Lattice computations have shown very interesting phenomena. The asymmetry shows a jump at the deconfinement phase transition, beyond which it approaches its perturbative value. At temperatures lower than the critical temperature, it shows an exponential behavior with in the exponent a mass smaller than the lowest glueball mass. In this talk we present research done on this asymmetry, using a generalization of analytical methods developed to study . The purpose is to shed more insight on the findings of Chernodub and Ilgenfritz.

Roman domination and Mycieleki's structure in graphs

Subjects: subject: Combinatorics (math.CO)

description: For a graph $G=(V,E)$, a function $f:V\rightarrow \{0,1,2\}$ is called Roman dominating function (RDF) if for any vertex $v$ with $f(v)=0$, there is at least one vertex $w$ in its neighborhood with $f(w)=2$. The weight of an RDF $f$ of $G$ is the value $f(V)=\sum_{v\in V}f(v)$. The minimum weight of an RDF of $G$ is its Roman domination number and denoted by $γ_ R(G)$. In this paper, we first show that $γ_{R}(G)+1\leq γ_{R}(μ(G))\leq γ_{R}(G)+2$, where $μ(G)$ is the Mycielekian graph of $G$, and then characterize the graphs achieving equality in these bounds. Then for any positive integer $m$, we compute the Roman domination number of the $m$-Mycieleskian $μ_{m}(G)$ of a special Roman graph $G$ in terms on $γ_R(G)$. Finally we present several graphs to illustrate the discussed graphs.

description: In superconducting qubits, suppression of spontaneous emission is essential to achieve fast dispersive measurement and reset without sacrificing qubit lifetime. We show that resonator-mediated decay of the qubit mode to the feedline can be suppressed using destructive interference, where the readout resonator is coupled to the feedline at two points. This "interferometric Purcell filter" does not require dedicated filter components or impedance mismatch in the feedline, making it suitable for applications such as all-pass readout. We design and fabricate a device with the proposed scheme and demonstrate suppression of resonator-mediated decay that exceeds 2 orders of magnitude over a bandwidth of 400 MHz for a resonator linewidth of 13.8 MHz.

Tailoring the migration capacity of regulatory T cells to enhance their efficacy as a cellular therapy

description: Cell-based therapy with CD4⁺FOXP3⁺ Regulatory T cells (Tregs) has the potential to be an effective treatment to limit organ transplant rejection, graft-versus-host disease and autoimmunity. Yet, challenges for the successful implementation of Treg therapy include difficulties in isolating and expanding homogeneous cell populations while preserving their suppressive function. Further, to be effective, Tregs may need to express homing receptors for migration to inflammatory or tissue sites. The aims of this research were to investigate an alternate source of therapeutic Tregs, to test whether Treg homing capacity could be tailored, and to investigate the migratory capacity of engineered antigen-specific Tregs. To evaluate pediatric thymus – routinely removed during cardiac surgery – as a source of therapeutic Tregs, I isolated thymic Tregs as CD4⁺CD25⁺ cells using different protocols. Large numbers of thymic Tregs could be isolated and expanded in vitro to clinically relevant numbers while maintaining high FOXP3-expression. Thymic Tregs did not secrete pro-inflammatory cytokines and were suppressive in vitro and in a humanized mouse model. Next, I tested whether the addition of cytokines or metabolites to the expansion culture could tailor the homing capacity of thymic Tregs towards inflammatory and specific tissue sites. Addition of IFN-gamma and IL-12 yielded CXCR3⁺TBET⁺FOXP3⁺ Th1-Tregs with migratory capacity to Th1-chemokines in vitro while maintaining their Treg phenotype. Adding retinoic acid to cultures induced expression of the gut-homing receptors alpha4beta7-integrin and CCR9 on Tregs and elevated their gut-relevant suppressive mechanisms. Homing-receptor-tailored Tregs were epigenetically stable even after long-term exposure to inflammatory conditions and they were suppressive in vivo. Finally, I investigated how engineered antigen-specificity affected trafficking of Tregs in vivo, by transducing them with a chimeric antigen receptor (CAR) targeting HLA-A2. I tracked homing of luciferase-transduced HLA-A2-CAR Tregs longitudinally in vivo and found that HLA-A2-CAR Tregs migrated to and proliferated at HLA-A2-expressing skin grafts and could migrate to draining lymph nodes. Tregs recovered from lymph nodes maintained FOXP3- and CAR-expression. Collectively, these studies show that thymic Tregs could be used as an ‘off-the-shelf’ cellular therapy and tailoring Treg homing capacity offers a new and clinically-applicable approach to improving the potency and specificity of Treg therapy.

description: We investigate the problem of finding the optimal convex decomposition of a bipartite quantum state into a separable part and a positive remainder, in which the weight of the separable part is maximal. This weight is naturally identified with the degree of separability of the state. In a recent work, the problem was solved for two-qubit states using semidefinite programming. In this paper, we describe a procedure to obtain the optimal decomposition of a bipartite state of any finite dimension via a sequence of semidefinite relaxations. The sequence of decompositions thus obtained is shown to converge to the optimal one. This provides, for the first time, a systematic method to determine the so-called optimal Lewenstein-Sanpera decomposition of any bipartite state. Numerical results are provided to illustrate this procedure, and the special case of rank-2 states is also discussed.

description: A gauge-invariant quantum theory of the Friedmann-Robertson-Walker (FRW) universe with dust is studied in terms of the Ashtekar variables. We use the reduced phase space quantization which has following advantages: (i) fundamental variables are all gauge invariant, (ii) there exists a physical time evolution of gauge-invariant quantities, so that the problem of time is absent and (iii) the reduced phase space can be quantized in the same manner as in ordinary quantum mechanics. In the FRW model, the dynamical components of the Ashtekar variables are given by a single quantity $p$ and its conjugate momentum, where $p$ is related to the scale factor $a$ as $a\propto \sqrt{|p|}$ and its sign gives the orientation of triads. We solve a scattering problem in terms of ingoing and outgoing energy eigenstates. We show that the incident wave is reflected in rate $1/4$ and transmitted in rate $3/4$ at the classical singularity $p=0$. Analyzing the dynamics of a wave packet, we show that the classical initial singularity is replaced by a big bounce in quantum theory. A possible interpretation of the result is that the wave function of the universe has been in a superposition of states representing right-handed and left-handed systems before the big bounce.

Quantum search algorithms on a regular lattice

description: Quantum algorithms for searching one or more marked items on a d-dimensional lattice provide an extension of Grover's search algorithm including a spatial component. We demonstrate that these lattice search algorithms can be viewed in terms of the level dynamics near an avoided crossing of a one-parameter family of quantum random walks. We give approximations for both the level-splitting at the avoided crossing and the effectively two-dimensional subspace of the full Hilbert space spanning the level crossing. This makes it possible to give the leading order behaviour for the search time and the localisation probability in the limit of large lattice size including the leading order coefficients. For d=2 and d=3, these coefficients are calculated explicitly. Closed form expressions are given for higher dimensions.

description: 19F isotropic chemical shifts for alkali, alkaline earth and rare earth of column 3 basic fluorides are measured and the corresponding isotropic chemical shieldings are calculated using the GIPAW method. When using PBE exchange correlation functional for the treatment of the cationic localized empty orbitals of Ca2+, Sc3+ (3d) and La3+ (4f), a correction is needed to accurately calculate 19F chemical shieldings. We show that the correlation between experimental isotropic chemical shifts and calculated isotropic chemical shieldings established for the studied compounds allows to predict 19F NMR spectra of crystalline compounds with a relatively good accuracy. In addition, we experimentally determine the quadrupolar parameters of 25Mg in MgF2 and calculate the electric field gradient of 25Mg in MgF2 and 139La in LaF3 using both PAW and LAPW methods. The orientation of the EFG components in the crystallographic frame, provided by DFT calculations, is analysed in term of electron densities. It is shown that consideration of the quadrupolar charge deformation is essential for the analysis of slightly distorted environments or highly irregular polyhedra.

The Cedar Project : understanding the relationship between child apprehension, cultural connectedness and trauma among young Indigenous mothers who have used drugs in two Canadian cities
Creators: name: Ritland, Lisa Sherrill

description: Background: Indigenous leaders are deeply concerned about the overrepresentation of Indigenous children in Canada’s child welfare system. However, few studies have addressed the relationship between family disruption, cultural connectedness, substance use and mental health among Indigenous families within the context of historical and intergenerational trauma. Objective: First, a scoping review examined culturally safe services and interventions to support Indigenous families involved in substance use. Second, the incidence of child apprehension and association with suicide attempt was investigated among young Indigenous mothers who have used drugs. Methods: A scoping review was conducted of the empirical literature examining interventions for Indigenous families involved in substance use in Canada, Australia, New Zealand and the United States. For longitudinal analysis, we utilized data collected every 6 months between 2008 and 2016 by the Cedar Project, a prospective cohort study involving young Indigenous people who use drugs in Vancouver and Prince George, British Columbia, Canada. A recurrent event Cox proportional hazards model was used to estimate the independent effect of child apprehension on suicide attempt among female participants. Unadjusted and adjusted hazard rations (HRs) were reported with 95% confidence intervals. Results: There were few studies in the research literature evaluating culturally safe services and interventions for Indigenous families involved in substance use. We found an independent association between child apprehension and suicidal behaviour: young Indigenous mothers who reported recent child apprehension were twice as likely to attempt suicide over the study period. We discovered other risk factors for suicidal behaviour, including having a parent attend residential school, sexual assault, violence, and overdose. Young Indigenous mothers who had a traditional language spoken in the home growing up were almost half as likely to attempt suicide. Conclusion: Our results provide evidence to suggest the child welfare system perpetuates intergenerational trauma among Indigenous communities. Young Indigenous mothers in this study were more likely to attempt suicide after their children were apprehended, which was compounded by historical and lifetime trauma. However, cultural connectedness may protect against suicidal behaviour in this population. Indigenous jurisdictional control over child welfare and more culturally safe services are urgently needed to keep families together.
