description: Low soil nitrogen is among the most important abiotic stresses limiting maize production in the highlands of Ethiopia. Information on hybrid performance and combining ability of maize inbred lines for grain yield and agronomic traits under low nitrogen stress is crucial to design appropriate breeding strategies for the development of enhanced maize cultivars. The objective of the present study was to estimate combining abilities of double haploid (DH) maize inbred lines for grain yield and related traits under optimum nitrogen and low nitrogen (N stress) condition. A total of 36 diallel crosses generated by crossing nine maize DH lines using half diallel mating scheme and four standard checks were studied for different desirable agronomic traits during 2017 cropping season at Ambo optimum nitrogen and Low nitrogen environments. The genotypes were evaluated in alpha lattice design replicated twice in both environments. Analyses of variances showed significant mean squares due to crosses for most traits studied. At optimum nitrogen condition, the highest grain yield was obtained from crosses L4 x L8 (9.57 t ha-1), L4 x L7 (8.67 t ha-1), L1 x L3 (8.36 t ha-1), L6 x L8 (8.27 t ha-1) and L3 x L4 (8.00 t ha-1), whereas at low nitrogen condition, L2 × L4 (6.74 t ha-1) and L4 × L8 (5.15 t ha-1) were crosses with higher grain yield values. Mean squares due to general (GCA) and specific (SCA) combining abilities were significant for most of the traits under both conditions. This indicates that both additive and non-additive gene actions are important in the inheritance of these traits. Relatively larger GCA over SCA variances were observed in the current study for most studied traits revealing the predominance of additive gene action in controlling these traits. L3 and L8 were found as good combiners for grain yield at optimum N environment, whereas L2, L4 and L7 were good general combiners under low N stress condition. L4 and L8 were good combiners for grain yield in combine analysis across environments and hence were promising parents for hybrid cultivars development. Based on SCA effects, L1×L5, and L4×L7 were identified as promising hybrids for majority of traits studied in combined analysis across environments.

description: Reactive brilliant red X-3B (RBRX-3B) wastewater is difficult to decolourise, not readily biodegradable, and large in quantity. Therefore, the efficient removal of RBRX-3B is crucial. In this paper, a green and efficient electrochemical-electro-Fenton system with Fe3O4-modified carbon felt bag cathode (ECEF-Fe3O4) was set up to degrade RBRX-3B wastewater. Experiments confirmed that the removal of RBRX-3B by ·OH or H2O2 is quite low, and RBRX-3B can be completely oxidised and degraded directly on the anode. Long-cycle experimental data further shows that the degradation efficiency of RBRX-3B on the anode is 100% at 70 min at the reaction rate constants (k) of 0.071 min−1 in ECEF-Fe3O4 while that of RBRX-3B on the cathode is only 16.8 ± 0.9%. The generation of ·OH is mainly catalysed through the internal cycling of Fe3+/Fe2+ within Fe3O4 on the cathode, and the generation and annihilation of ·OH on the cathode enhance the oxidation efficiency of the anode, achieving the green and effective removal of RBRX-3B by the anode in ECEF-Fe3O4.

description: Starting from the fluctuating Boltzmann equation for smooth inelastic hard spheres or disks, closed equations for the fluctuating hydrodynamic fields to Navier-Stokes order are derived. This requires to derive constitutive relations for both the fluctuating fluxes and the correlations of the random forces. The former are identified as having the same form as the macroscopic average fluxes and involving the same transport coefficients. On the other hand, the random force terms exhibit two peculiarities as compared with their elastic limit for molecular systems. Firstly, they are not white, but have some finite relaxation time. Secondly, their amplitude is not determined by the macroscopic transport coefficients, but involves new coefficients.
Static isolated horizons: SU(2) invariant phase space, quantization, and black hole entropy

description: We study the classical field theoretical formulation of static generic isolated horizons in a manifestly SU(2) invariant formulation. We show that the usual classical description requires revision in the non-static case due to the breaking of diffeomorphism invariance at the horizon leading to the non conservation of the usual pre-symplectic structure. We argue how this difficulty could be avoided by a simple enlargement of the field content at the horizon that restores diffeomorphism invariance. Restricting our attention to static isolated horizons we study the effective theories describing the boundary degrees of freedom. A quantization of the horizon degrees of freedom is proposed. By defining a statistical mechanical ensemble where only the area A of the horizon is fixed macroscopically-states with fluctuations away from spherical symmetry are allowed-we show that it is possible to obtain agreement with the Hawking's area law---S = A/4 (in Planck Units)---without fixing the Immirzi parameter to any particular value: consistency with the area law only imposes a relationship between the Immirzi parameter and the level of the Chern-Simons theory involved in the effective description of the horizon degrees of freedom.

description: We consider the cold bosonic ensemble trapped by a helical interference pattern in the optical \textit{loop} scheme. This rotating helical potential is produced by the two slightly detuned counter propagating Laguerre-Gaussian laser beams with counter directed orbital angular momenta $\pm \ell\hbar $. The detuning $δω$ may occur due to rotational Doppler effect. The superfluid hydrodynamics is analysed for the large number of trapped atoms in Thomas-Fermi approximation. For the highly elongated trap the Gross-Pitaevskii equation is solved in a slowly varying envelope approximation. The speed of axial translation and angular momenta of interacting atomic cloud are evaluated. In the $T \rightarrow 0$ limit the angular momentum of the helical cloud is expected to be zero while toroidal trapping geometry leads to $2\ell \hbar$ angular momentum per trapped atom.

description: The environmental diversity associated climatic variables in the micro environments are anticipated to change over times. This study aimed to examine precipitation concentration and anomaly indices, and trends of climatic variables over micro-environments of Iluabbabora zone. Climatic data were obtained from NASA’s dataset, recorded from 1981–2018. Precipitation concentration indices were estimated and interpolated using an inverse distance weighting. The frequency and percentile of drier and wetter periods was analyzed using standardized precipitation anomaly index model. The Mann Kendall trend test was used to determine trends of seasonal and annual temperature and precipitation. Results show that both seasonal and annual precipitation concentrations were inconsistently distributed among the seasons and neighboring locations. A strong concentration index (23) was observed in Meko during summer season. Standardized precipitation anomaly indices Analyses indicated that the frequency and percentiles of the driest years were more pronounced than wettest periods in all locations. The higher percentage (55.41%) drier period above the normal was observed in Bedele followed by Birbisa (54.05%). Trends analyses of seasonal mean temperature and precipitation were inconsistently changed with respect to the seasons and locations. The spring minimum temperature of Bedele, winter minimum temperature of all locations and annual minimum temperature of Gore were significantly warmed (P>0.05). Similarly, the spring season of Birbisa, and Gore, winter summer seasons and annual maximum temperature of Bedele and Gore locations were significantly increased (P<0.05) whereas the spring and summer seasons of Bedele, annual and summer season precipitation of Gore were significantly decreased (P<0.05). Therefore, the study confirmed that variability and change of climatic variables in different micro environments were rapidly and indifferently tracked toward severe climatic shocks, and suggesting that sound implementations of existing forest protection and soil water conservations in the study area.

The resulting theory turns out to be wedge-local and non-isomorphic to the initial one for a class of theories, including the free charged Dirac field. The properties of deformed models coming from inclusions of CAR-algebras are studied in detail.

description: Gli strumenti professionali a supporto della cybersecurity sono molteplici. Tra le soluzioni tecniche più comuni che negli ultimi anni hanno visto grandi evoluzioni in termini di complessità e funzionalità figurano principalmente i firewall, che rappresentano una delle risorse principali per garantire la sicurezza di rete. Negli ultimi anni il firewall tradizionale è stato superato da soluzioni più innovative, oggi giorno si preferisce infatti parlare di UTM (Unified Threat Management) oppure NGFW (Next Generation Firewall). Il presente progetto di diploma intende, in un primo momento, analizzare queste soluzioni studiandone particolarità e caratteristiche tecniche. In seguito, si prefigge l’obiettivo di scegliere una soluzione firewall open-source attualmente presente sul mercato ed estenderla sviluppando plugin ad hoc che possano aggiungere delle funzionalità tipiche di un firewall di prossima generazione. Il primo plugin sviluppato implementa il protocollo ICAP e si occupa di effettuare una scansione in tempo reale dei contenuti scaricati all’interno della rete. Questo permette ad amministratori di rete di individuare e bloccare potenziali minacce ancor prima che queste vengano introdotte nei computer degli utenti. Il secondo plugin sviluppato si occupa invece di integrare il servizio di messaggistica istantanea Telegram all’interno del firewall scelto, in modo tale da permettere l’invio di notifiche qualora determinati eventi dovessero verificarsi. Infine, è stata configurata una piattaforma adibita al data science e all’esecuzione di algoritmi di machine learning, dove verranno collezionati i log prodotti dal firewall e sarà possibile visualizzare report dettagliati in tempo reale sullo stato della rete.

description: The inevitable UV aging of microplastics (MPs) is one of the key factors affecting their interaction with antibiotics. In this study, polyethylene (PE) and polystyrene (PS) MPs were aged with UV irradiation. The adsorption isotherms and kinetics of ciprofloxacin (CIP) to virgin and aged MPs were investigated through various models, and the effects of pH on the adsorption amount were explored. Characterization revealed that the surfaces of aged MPs became rougher, and the hydrophilicity increased. These aged MPs were still in the early stage of aging on the basis of their carbonyl index (CI) (<0.2) and O/C (<0.04) values. The adsorption isotherms indicated that the adsorption mechanism of aged PE was different from that of virgin PE. Compared with virgin PE, the adsorption amount of aged PE increased by 87.80–95.45%, and the adsorption rate decreased by 65.52–80.74%. However, aging did not significantly affect the equilibrium adsorption amount or adsorption rate of aged PS. The external diffusion rate (Kext) (about 2.29–0.36 h−1) was almost 30 times greater than the internal diffusion rate (Kint) in the film-pore mass transfer (FPMT) model, indicating that CIP adsorption rate was dominated by external diffusion. A hydrated functional zone is thought to form around aged MPs, thus changing the adsorption mechanism and adsorption amount of aged PE. Therefore, more attention should be given to alterations in the hydrated functional zone in the early stage of MPs aging.
Granzyme B mediates cleavage of Thrombospondin-2 : impact on keratinocyte viability and adhesion
Creators: name: Wilhelm, Anna-Catharina
Publisher: name: University of British Columbia

description: The epidermis, consisting of keratinocytes, is the first defense against the exterior environment of the skin. Integral to maintaining the homeostasis of skin function by aiding in thermoregulation, fluid retention, and pathogen defense, the extracellular matrix composition aids in regulating keratinocyte migration after injury. Impaired healing processes can progress into chronic non-healing wounds, leading to infection and mortality. Granzyme B (GzmB) is a serine protease, significantly elevated in chronic non-healing wounds. GzmB impairment of wound healing is attributed to its ability to sustain its proteolytic activity and downstream inflammation, inhibiting wound repair and tissue remodeling following injury. GzmB is classically known for its intracellular role in cytotoxic lymphocyte-mediated apoptosis. Recent evidence demonstrates that extracellular GzmB has the ability to cleave a variety of important extracellular proteins. Thrombospondin-2 (TSP-2) is an extracellular glycoprotein secreted by a variety of cells known to be involved in cell-cell and cell-matrix interactions. TSP-2 has been reported to impair viability, adhesion, and migration in endothelial cells and squamous carcinoma cells. Although extensive studies have been done with TSP-2, literature investigating the role of TSP-2 in the skin has largely been neglected. I hypothesized that GzmB cleaves TSP2, and GzmB cleavage of TSP-2 mediates extracellular matrix disorganization, altered keratinocyte viability, and reduced adhesion. To investigate this hypothesis purposed two aims. In the first aim, cell-free protease assays were utilized to determine whether TSP-2 is a proteolytic substrate of GzmB. In the second aim, the impact of TSP-2-mediated cleavage was assessed using cultured human keratinocytes. TSP-2 was cleaved by GzmB in a time- and dose-dependent manner. Further, while GzmB-mediated TSP-2 cleavage did not affect cell viability, it did reduce cellular adhesion in a dose-dependent manner. In summary, TSP-2 is a proteolytic substrate of GzmB and such cleavage interferes with keratinocyte adhesion.

description: Thin-film nanocomposite (TFN) membranes with a polyamide (PA) active layer modified with carbon nanotubes (CNTs) hold promise for water desalination and wastewater reuse via forward osmosis (FO). We hypothesise that modifying the PA active layer with hydroxyl-functionalised multi-wall carbon nanotubes (f-MWCNTs) will enhance the water flux of the FO membrane while maximising salt rejection. TFN membranes were modified using in situ interfacial polymerisation, with varying f-MWCNT mass content to minimise agglomeration. These modified FO membranes are designated as CTFN-x, where x represents the mass content of f-MWCNTs, ranging from 0.001%, CTFN-1 to 0.008%, CTFN-8 (w/v). The surface properties of CTFN-x were characterised using electron microscopy, atomic force microscopy, and molecular spectroscopy. IR spectroscopic data confirm the successful adherence of f-MWCNTs as a bridging agent between the 1,3-phenylenediamine (MPD) and trimesoyl chloride (TMC) polymers, preserving FO membrane integrity. The CTFN-4 FO membrane shows the highest water flux (29 LMH) and the lowest reverse salt flux (2.90 gHM), attributed to preferential water flow channels in the f-MWCNTs. The integration of f-MWCNTs into the active layer improved water flux, reduced reverse salt flux, and enhanced the antifouling properties of FO membranes.

description: We investigated purely gravitational domain wall solutions to Horava nonrelativistic theory of gravity with detailed balance in 3 + 1 dimensions. We find that for arbitrary values of the running parameter λ > 1/3 two branches of membrane solutions exist. For positive values of the cosmo-logical constant, the solution represents a space that is bounded in the transverse direction, with singularities sitting at each of the boundaries. For negative values of the cosmological constant, the solution contains a single membrane sitting at the center of a space, which extends infinitely in the transverse direction approaching a Lifshitz metric. In that case there is one additional degenerate branch, for which the lapse function is undetermined.

description: Exclusive boarding schools in social environments where the meritocratic norm is prevalent are faced with a tension between parents’ desire to give their children a head start in the competition for educational qualifications, social prestige and jobs on the one hand and the powerful social norm of advancement by merit under conditions of “equal opportunity” on the other. This article looks at how two exclusive boarding schools, Eton College in England and Schule Schloss Salem in Germany, deal with this double challenge in presenting themselves to their environment, attempting to preserve social legitimacy while staying attractive to their clientele. The article shows that the ways in which the schools deal with these conflicting demands depends strongly on the differing systems contexts they find themselves in.

description: Dynamical decoupling (DD) is a promising tool for preserving the quantum states of qubits. However, small imperfections in the control pulses can seriously affect the fidelity of decoupling, and qualitatively change the evolution of the controlled system at long times. Using both analytical and numerical tools, we theoretically investigate the effect of the pulse errors accumulation for two aperiodic DD sequences, the Uhrig's DD UDD) protocol [G. S. Uhrig, Phys. Rev. Lett. {\bf 98}, 100504 (2007)], and the Quadratic DD (QDD) protocol [J. R. West, B. H. Fong and D. A. Lidar, Phys. Rev. Lett {\bf 104}, 130501 (2010)]. We consider the implementation of these sequences using the electron spins of phosphorus donors in silicon, where DD sequences are applied to suppress dephasing of the donor spins. The dependence of the decoupling fidelity on different initial states of the spins is the focus of our study. We investigate in detail the initial drop in the DD fidelity, and its long-term saturation. We also demonstrate that by applying the control pulses along different directions, the performance of QDD protocols can be noticeably improved, and explain the reason of such an improvement. Our results can be useful for future implementations of the aperiodic decoupling protocols, and for better understanding of the impact of errors on quantum control of spins.

Detailed analytical and numerical calculations show that, while some of the assumptions underlying the standard evaporation paradigm are borne out, several are not. Furthermore, if the black hole is initially macroscopic, the evaporation process exhibits remarkable universal properties (which are distinct from the features observed in the simplified, exactly soluble models). Although the literature on CGHS black holes is quite rich, these features had escaped previous analyses, in part because of lack of required numerical precision, and in part because certain properties and symmetries of the model were not fully recognized. Finally, our results provide support for the full quantum gravity scenario recently developed by Ashtekar, Taveras and Varadarajan.

description: Non-Abelian discrete family symmetries play a pivotal role in the formulation of models with tri-bimaximal lepton mixing. We discuss how to obtain symmetries such as A4, semidirect product of Z7 and Z3, and Delta(27) from an underlying SU(3) gauge symmetry. Higher irreducible representations are required to achieve the spontaneous breaking of the continuous group. We present methods of identifying the required vacuum alignments and discuss in detail the symmetry breaking potentials.

Creators: name: Thota, Srinivasarao
Publisher: name: Journal of Science and Sustainable Development
Year: 2019

description: In this paper, we discuss a model of two-space food chain consisting of the population of ecology of foxes (the predator) and rabbits (prey) in Awash National park, Ethiopia. The study is based on formulation of a mathematical model to study the dynamics of the population densities and analyzing the stability of equilibrium points of the prey-predator model. The aim of this model is to explore the behavior of a simple model by considering a population of foxes, and rabbits. This model is constituted by a system of nonlinear decoupled ordinary differential equations. By using perturbed method, we identify the nature of the system at each equilibrium point. The stability analysis of a prey-predator model is discussed with numerical simulations.

description: The problem of the two-level atom laser is studied analytically. The steady-state solution is expressed as a continued fraction, and allows for accurate approximation by rational functions. Moreover, we show that the abrupt change observed in the pump dependence of the steady-state population is directly connected with the transition to the lasing regime. The condition for a sharp transition to Poissonian statistics is expressed as a scaling limit of vanishing cavity loss and light-matter coupling, $κ\to 0$, $g \to 0$, such that $g^2/κ$ stays finite and $g^2/κ> 2 γ$, where $γ$ is the rate of atomic losses. The same scaling procedure is also shown to describe a similar change to Poisson distribution in the Scully-Lamb laser model too, suggesting that the low-$κ$, low-$g$ asymptotics is of a more general significance for the laser transition.

description: The study of the Luminosity Function (LF) of Lyman Break Galaxies (LBGs) at z=7 is important for ascertaining their role in the reionization of the Universe. We perform a detailed and critical analysis of the statistical and systematic errors in the z~7 LF determination: we have assembled a large sample of candidate LBGs at z~7 from different surveys, spanning a large variety of areas and depths. In particular, we have combined data from the deep (J<27.4) and ultradeep (J<29.2) surveys recently acquired with the new WFC3 NIR camera on HST, over the GOODS-ERS and the HUDF fields, with ground based surveys in wide and shallow areas from VLT and Subaru. We have used public ACS images in the z-band to select z-dropout galaxies, and other public data both in the blue (BVI) and in the red bands to reject possible low-redshift interlopers. We have compared our results with extensive simulations to quantify the observational effects of our selection criteria as well as the effects of photometric scatter, color selections or the morphology of the candidates. We have found that the number density of faint LBGs at z~7 is only marginally sensitive to the color selection adopted, but it is strongly dependent from the assumption made on the half light distributions of the simulated galaxies, used to correct the observed sample for incompleteness. The slope of the faint end of the LBGs LF has thus a rather large uncertainty, due to the unknown distribution of physical sizes of the z~7 LBGs. We conclude that galaxies at z~7 are unable to reionize the Universe unless there is a significant evolution in the clumpiness of the IGM or in the escape fraction of ionising photons or, alternatively, there is a large population of z~7 LBGs with large physical dimensions but still not detected by the present observations.

description: The adjoint method introduced in [Eva] and [Tra] is used, to construct analogs to the Aubry-Mather measures for non convex Hamiltonians. More precisely, a general construction of probability measures, that in the convex setting agree with Mather measures, is provided. These measures may fail to be invariant under the Hamiltonian flow and a dissipation arises, which is described by a positive semidefinite matrix of Borel measures. However, in the important case of uniformly quasiconvex Hamiltonians the dissipation vanishes, and as a consequence the invariance is guaranteed.

description: We study the effect of the impurity density on lifetimes and relaxation lengths of electron spins in the presence of a static electric field in a n-type GaAs bulk. The transport of electrons and the spin dynamics are simulated by using a semiclassical Monte Carlo approach, which takes into account the intravalley scattering mechanisms of warm electrons in the semiconductor material. Spin relaxation is considered through the D'yakonov-Perel mechanism, which is the dominant mechanism in III-V semiconductors. The evolution of spin polarization is analyzed by computing the lifetimes and depolarization lengths as a function of the doping density in the range 10^{13} - 10^{16} cm^{-3}, for different values of the amplitude of the static electric field (0.1 - 1.0 kV/cm). We find an increase of the electron spin lifetime as a function of the doping density, more evident for lattice temperatures lower than 150 K. Moreover, at very low intensities of the driving field, the spin depolarization length shows a nonmonotonic behaviour with the density. At the room temperature, the spin lifetimes and depolarization lengths are nearly independent on the doping density. The underlying physics is analyzed.

description: The objective was to assess impacts of deforestation on selected soil fertility status in Chellia District, West Shoa zone of Oromia Regional National State, Ethiopia. The experiment was undertaken in selected deforested areas for soil fertility status by descriptive cross-sectional method which describes and obtains relevant and various forms of data concerning the existing current status of the study area. The data for the study were collected through field observation and laboratory test. Two representative composite soil samples were collected in zigzag manner from the upper (0-20 cm) depth of the top soil from the forest and deforested lands. The study was mainly focused on analyzing the soil physicochemical and fertility status between forest and deforested lands. The cumulative values of deforestation were decreasing the marginal status of soil nutrients, showing that the overall soil condition in the deforested land was deteriorating and getting below the condition of the soils under the forest lands. The comparisons between the forest and deforested lands revealed a highly significant difference on major soil fertility parameters. Therefore, there is a need to develop sustainable forest management and practicing afforestation and reforestation programs to overcome the deterioration of soil fertility of the present study area.

description: Let L->M be a Hermitian line bundle over a compact manifold. Write S for the space of all unitary connections in L whose curvatures define symplectic forms on M and G for the group of unitary bundle isometries of L, which acts on S by pull-back. The main observation of this note is that S carries a G-invariant symplectic structure, there is a moment map for the G-action and that this embeds the components of S as G_0-coadjoint orbits (where G_0 is the component of the identity). Restricting to the subgroup of G which covers the identity on M, we see that prescribing the volume form of a symplectic structure can be seen as finding a zero of a moment map. When M is a Kähler manifold, this gives a moment-map interpretation of the Calabi conjecture. We also describe some directions for future research based upon the picture outlined here.

description: Open innovation has attracted an avalanche of interests from many practitioners and scholars, and

is gradually becoming an acceptable scientific and managerial paradigm over the past few decades.

Traditionally, however, innovative activities ought to be confidential within certain groups or individuals

before the marketing process, and will be protected strictly by the intellectual property rights laws,

for the sake of innovators’ economic benefits and encouraging further innovation attempts. This paper

aims at addressing the question of how to stimulate firms and managers to invest more resources to

open innovation, and focuses on social inducement’s effectiveness, in the art of a pre-recorded video,

using an experimental approach. We established two open innovation investment models in which

investors decide to allocate resources to open and traditional innovation projects. In the first model,

we introduce the spillover effect and assume that traditional innovation projects may profit from open

innovation investment. We then consider uncertainty to make the investment more realistic in the second

model. The effect of social inducement on open innovation provision has been investigated in all

the three settings, i. e. No Video, Full Video and Half Video. The striking result is that social inducement

increases open innovation investment, but only if both induced subjects and non-induced subjects exist;

meanwhile, economic uncertainty also matters.
Gender Disparities in Utilization of Agricultural Information by Small Scale Farming Households in Ambo District of West Shewa Zone

description: Gender disparity in utilizing agricultural information affects the agricultural productivity of male and female households. Thus, this study was carried out to examine the gender disparities in utilizating agricultural informaation by small scale farming households in Ambo district. To achieve the objective of the study, both primary and secondary sources of data were used. Data were collected using semi-structured interview schedule, key informant interviews and focus group discussions; and analysed using descriptive satatistics and description. The study revealed that the majority of the farmers rely on informal sources of information from neighbors, friends and colleagues rather than from the extension workers. Particularily, information sources of women did not enable them to get adequate and reliable information. It cloud be attributed to less mobility of women to access information, women responsibilities for household and child-rearing activities and workload. Gender disparity made great difference in using agricultural information for farmers since mostly women are playing a reproductive role. Therefore, improving participation of women farmers in various areas of extension programmes could facilitate empowering farm women for better utilization of agricultural information.

Promoting perinatal mental health : personalizing treatment decision making strategies through decision-making support and pharmacogenetics
Creators: name: Hippman, Catriona Lynne
Publisher: name: University of British Columbia
Year: 2020

description: Problem: Depression during pregnancy affects 10-15% of women. Practice guidelines recommend that clinicians support women to make treatment decisions that are informed by the risks of both untreated depression and antidepressant use during pregnancy. However, there is minimal evidence regarding how women make these decisions or how clinicians can best support them. Purpose: To advance knowledge and understanding regarding women’s decision making about perinatal depression treatment through qualitative (QUAL) and quantitative (QUANT) studies. The QUAL purpose was to develop a constructivist grounded theory, within a feminist theoretical framework, of women’s perinatal depression treatment decision making. The QUANT purpose was to test the hypothesis that women with deleterious variants in the pharmacogenes CYP2D6 or CYP2C19, taking selective serotonin reuptake inhibitors (SSRIs) prenatally, would have more depression symptoms than women whose pharmacogenetic variants have been associated with normal SSRI metabolism. Methods (QUAL): Semi-structured interviews were conducted with purposively-sampled, pregnant/preconception women who had experienced depression. Iterative data collection and analysis, along with theoretical sampling, in the context of reflexive journaling, peer debriefing, and expert audit, culminated in a cohesive theoretical model. Methods (QUANT): Testing of CYP2D6 and CYP2C19 were performed as secondary analyses on two longitudinal cohorts of pregnant women taking SSRIs. The Kruskal-Wallis Test compared mean depression scores across four predicted metabolizer groups: 1) poor, 2) intermediate, 3) extensive, and 4) ultra-rapid. Results (QUAL): Participants’ (N=31) decision-making processes were complex and dynamic, and highly influenced by contextual factors - particularly stigma, patriarchy, privilege, and their emotional/cognitive environments. Participants navigated towards a decision, in a non-linear manner, between three clusters of decision-making activities: 1) seeking information, 2) making sense of information, and 3) self-soothing. Results (QUANT): There were no significant differences between mean depression scores across the four metabolizer groups (N=83; H(3)=.73, p=.87). Conclusions: The grounded theory provides insight into how women have made this decision, which can be useful both practically and emotionally. Evidence from the pharmacogenetic study clarifies the limitations of this field, which is especially vital in this era of direct-to-consumer genetic testing. Together, they can support patient-oriented decision making regarding perinatal maternal mental health.
