description: Macroautophagy/autophagy, an evolutionarily conserved degradative process essential for cell homeostasis and development in eukaryotes, involves autophagosome formation and fusion with a lysosome/vacuole. The soluble N-ethylmaleimide-sensitive factor attachment protein receptor (SNARE) proteins play important roles in regulating autophagy in mammals and yeast, but relatively little is known about SNARE function in plant autophagy. Here we identified and characterized two Arabidopsis SNAREs, AT4G15780/VAMP724 and AT1G04760/VAMP726, involved in plant autophagy. Phenotypic analysis showed that mutants of VAMP724 and VAMP726 are sensitive to nutrient-starved conditions. Live-cell imaging on mutants of VAMP724 and VAMP726 expressing YFP-ATG8e showed the formation of abnormal autophagic structures outside the vacuoles and compromised autophagic flux. Further immunogold transmission electron microscopy and electron tomography (ET) analysis demonstrated a direct connection between the tubular autophagic structures and the endoplasmic reticulum (ER) in vamp724-1 vamp726-1 double mutants. Further transient co-expression, co-immunoprecipitation and double immunogold TEM analysis showed that ATG9 (autophagy related 9) interacts and colocalizes with VAMP724 and VAMP726 in ATG9-positive vesicles during autophagosome formation. Taken together, VAMP724 and VAMP726 regulate autophagosome formation likely working together with ATG9 in Arabidopsis.

description: Background Early administration of intravenous (IV) caffeine (initiation within 2 days of life) is an effective treatment strategy for the management of apnoea of prematurity among infants. However, the safety and effectiveness of early administration of oral caffeine treatment is not be fully established. Aim We aimed to compare the effectiveness and safety of early versus late caffeine therapy on preterm infants’ clinical outcomes. Method A retrospective matched cohort study was conducted using data of patients admitted to neonatal intensive care units of two tertiary care hospitals between January 2016 and December 2018. The clinical outcomes and mortality risk between early caffeine (initiation within 2 days of life) and late caffeine (initiation ≥ 3 days of life) were compared. Results Ninety-five pairs matched based on gestational age were included in the study. Compared to late initiation, preterm infants with early caffeine therapy had: a shorter duration of non-invasive mechanical ventilation (median 5 days vs. 12 days; p < 0.001); shorter length of hospital stay (median 26 days vs. 44 days; p < 0.001); shorter duration to achieve full enteral feeding (median 5 days vs. 11 days; p < 0.001); and lower frequency of bronchopulmonary dysplasia (BPD) (4.5% vs. 12.9%; p = 0.045). They also had a reduced risk of osteopenia of prematurity (OP) (OR 0.209; 95% CI 0.085–0.509; p = 0.001). Conclusion Early oral caffeine therapy can potentially improve respiratory outcomes among infants with apnoea of prematurity. However, an increase in mortality associated with early caffeine therapy requires further investigation.Other Information Published in: International Journal of Clinical Pharmacy

description: Application of PV systems have great potential to meet the electricity needs of rural areas in a cost
effective way. However, there are concerns about the site determination of PV systems among the implementers and
project designers as the success of a project greatly depend on the proper selection of its site. A PV system design
should consider the parameters of energy resources, load demand and population density of the site. To address this
issue, a Geographic Information System (GIS) based method has been developed to select technically and financially
feasible sites of a given region. A GIS database with data on solar radiation, topography has been developed and
used for assessing the technical potential of the solar PV resource. It also considers the electricity demand, land use,
local potential and constraints such as electricity network coverage, river, road etc and thus identifies suitable areas
for installing PV systems. The financial analysis based on the Payback period (PB) identifies the financial viability
of the investment. The methodology has been applied to Sakonnakhon Province, Thailand. It is expected that the
output of this GIS model would help the project designers to select suitable sites for a PV system. In addition, policy
makers and planners could use this method as a decision support system for estimating the load demand, technical
and financial viability of these through easy visualization and could analyse either an installed project or a new
project to be considered for implementation. This paper describes the development of the method and details the
output. In addition, it also shows the application of the method, clearly showing the applicability of the developed
method using a suitable tool for assessing PV system.

description: The general approach for describing systems with Bose-Einstein condensate, where atoms interact through nonlocal pair potentials, is presented. A special attention is paid to nonintegrable potentials, such as the dipolar interaction potential. The potentials that are not absolutely integrable can have not well defined Fourier transforms. Using formally such not defined Fourier transforms leads to unphysical conclusions. For making the Fourier transform well defined, the interaction potential has to be regularized. This is illustrated by the example of dipolar interactions.

description: Background Critical appraisal aids in assessing the quality of scientific literature, which is central to the practice of evidence-based medicine. Several tools and guidelines are available for critiquing and assessing the quality of specific study types. However, limited guidance exists for critical appraisal of clinical pharmacokinetic studies. Aim We aimed to achieve experts’ consensus regarding the quality markers for clinical pharmacokinetic studies in an attempt to develop a critical appraisal tool. Method Quality markers related to clinical pharmacokinetic studies, were derived from the published literature and categorized according to manuscript reporting domains (abstract, introduction/background, methodology, results, discussion, and conclusion). Questions that aid in appraising pharmacokinetic studies were formulated from these quality markers. Experts were involved in a modified Delphi process to achieve a consensus regarding the formulated questions. The proposed tool was pilot tested on 30 recently published clinical pharmacokinetic studies. Inter-observer agreement was measured to determine the reliability of the included items. Results Twenty-five experts consented to participate. Three rounds of a modified Delphi survey were required to generate a consensus for a 21-item tool aimed at appraising the quality of clinical pharmacokinetic studies. When applied to 30 recently published clinical pharmacokinetic studies, most items scored fair to moderate levels of agreement (61.90–95.24%). Conclusion The clinical pharmacokinetic critical appraisal tool (CACPK) developed in this study consisted of 21 items aimed at helping an end-user to determine the quality of a pharmacokinetic study. Further studies are warranted to reaffirm the validity and reliability of the CACPK tool.Other Information Published in: International Journal of Clinical Pharmacy

description: This work proposes a laser-assisted metallization process out of a nickel electrolyte. A nickel seed layer is created utilizing a local laser irradiation of a silicon wafer immersed in a nickel solution. Since the grid pattern is directly defined by the laser, no additional masking layer is necessary for this process step. Subsequently this seed layer is thickened by light induced silver galvanic [1]. In this work different Ni solutions and laser configurations were analyzed. With the optimized parameters, silicon solar cells with efficiencies up to 13.4% could be reached.

description: Background For decades, vitamin K antagonists and specifically warfarin, have been the sole agents used orally to manage thromboembolic conditions, including stroke and venous thromboembolism (VTE). Several factors lead to warfarin dose variability, including genetic and non-genetic factors which made warfarin management challenging especially at the initiation phase. To overcome the challenges with warfarin dosing at initiation, strategies other than conventional or fixed dosing were introduced and explored. Aim In this narrative review, we aim to discuss and critique the different dosing strategies for warfarin at initiation with more focus on genotype-guided warfarin dosing and the most recent supporting evidence for and against its use. Method Medline database was searched from 1965 to July 2021. Articles addressing different warfarin dosing methods were screened for inclusion. Results A number of methods exist for warfarin initiation. Studies comparing different dosing methods for initiation yielded conflicting outcomes due to differences in study design, population studied, comparator, and outcomes measured. Conclusions Looking at the big picture, the use of genetic dosing for warfarin initiation can lead to better outcomes. Whether these better outcomes are clinically or economically beneficial remains controversial.Other Information Published in: International Journal of Clinical Pharmacy

Both can be realized in terms of generalized complex geometry. We identify a map which relates the complex and symplectic supersymmetric systems. In the semi-flat torus bundle setting this map corresponds to T-duality and suggest a way of extending the mirror transform to non-Kähler geometries.

description: Background Studies have highlighted advancing clinical pharmacy practice in Qatar. Objective To explore pharmacists’ aspirations and readiness to implement pharmacist prescribing. Setting Hamad Medical Corporation (HMC), the main provider of secondary and tertiary care. Method A sequential explanatory mixed-methods design. Questionnaire items were derived from the Consolidated Framework of Implementation Research (CFIR), in domains of: awareness/support; readiness; implementation; and facilitators and barriers. Following piloting, all pharmacists (n = 554) were invited to participate. Questionnaire data were analysed using descriptive and inferential statistics with principal component analysis of attitudinal items. Focus groups were recorded, transcribed and analysed using the Framework Approach. Main outcome measure Aspirations and readiness to implement pharmacist prescribing. Results The response rate was 62.8% (n = 348), with respondents highly supportive of implementation in Qatar (median 4, scale 0–5, extremely supportive). The majority (64.9%, n = 226) considered themselves ready, particularly those more senior (p < 0.05) and classifying themselves innovative (p < 0.01). Outpatient (72.9%, n = 221 agreeing) and inpatient (71.1%, n = 218 agreeing) HMC settings were those perceived as being most ready. PCA identified 2 components, with ‘personal attributes’ being more positive than ‘prescribing support’. Facilitators were access to records, organizational/management support and the practice environment, with physician resistance and scope of practice as barriers. Focus groups provided explanation, with themes in CFIR domains of innovation characteristics, characteristics of individuals and the inner setting. Conclusion HMC pharmacists largely aspire, and consider themselves ready, to be prescribers with inpatient and outpatient settings most ready. CFIR domains and constructs identified as facilitators and barriers should be focus for implementation.Other Information Published in: International Journal of Clinical Pharmacy

description: This paper introduces a catalog of gravitational waveforms from the bank of simulations by the numerical relativity effort at Georgia Tech. Currently, the catalog consists of 452 distinct waveforms from more than 600 binary black hole simulations: 128 of the waveforms are from binaries with black hole spins aligned with the orbital angular momentum, and 324 are from precessing binary black hole systems. The waveforms from binaries with non-spinning black holes have mass-ratios $q = m_1/m_2 \le 15$, and those with precessing, spinning black holes have $q \le 8$. The waveforms expand a moderate number of orbits in the late inspiral, the burst during coalescence, and the ring-down of the final black hole. Examples of waveforms in the catalog matched against the widely used approximate models are presented. In addition, predictions of the mass and spin of the final black hole by phenomenological fits are tested against the results from the simulation bank. The role of the catalog in interpreting the GW150914 event and future massive binary black-hole search in LIGO is discussed. The Georgia Tech catalog is publicly available at einstein.gatech.edu/catalog.

description: In this work we present a method to measure the electroluminescence (EL)-based dark IV curve of
solar cells. By comparing this EL-IV curve with conventional dark IV curves, we are able to distinguish between
series and shunt resistance losses in the EL signal of both solar cells and single solar cells interconnected and
encapsulated in a solar module. Together with the open circuit voltage estimation based on the EL signal, we
demonstrate a useful method to reveal process failures leading to series and shunt resistance problems by
qualitatively and quantitatively comparing the EL signal of single solar cells before and after module production.

description: Cross-section, vector-polarization, and tensor-polarization distributions are calculated for the reactions $e^+ e^- \rightarrow \bar{p}p$ and $e^+ e^- \rightarrow \barΛ Λ$. Each reaction requires six characteristic functions that are bilinear in the, possibly complex, electromagnetic form factors, denoted $G_E(P^2)$ and $G_M(P^2)$, of $p$ and $Λ$. For the hyperon reaction also the joint-decay distributions of $Λ$ and $\barΛ$ are calculated. Their knowledge allow a complete determination of the hyperon electromagnetic form factors, without measuring hyperon spins. We explain how this is done in practice. For some tensor-polarization components our results are in conflict with previously repeatedly published distributions.

description: Single crystals of RPd${_2}$P${_2}$ (R=Y, La-Nd, Sm-Ho, Yb) were grown out of a high temperature solution rich in Pd and P and characterized by room-temperature powder X-ray diffraction, anisotropic temperature- and field-dependent magnetization and temperature-dependent in-plane resistivity measurements. In this series, YPd${_2}$P${_2}$ and LaPd${_2}$P${_2}$ and YbPd${_2}$P${_2}$ (with Yb$^{+2}$) are non local-moment bearing, whereas CePd${_2}$P${_2}$ and PrPd${_2}$P${_2}$ order at low temperature with a ferromagnetic component along the crystallographic c-axis. The rest of the series manifest low temperature antiferromagnetic ordering. EuPd${_2}$P${_2}$ has Eu$^{+2}$ ions and both EuPd${_2}$P${_2}$ and GdPd${_2}$P${_2}$ have isotropic paramagnetic susceptibilities consistent with $L = 0$ and $J=S=\frac{7}{2}$ and exhibit multiple magnetic transitions. For R=Eu-Dy, there are multiple, $T>1.8$ K transitions in zero applied magnetic field and for R=Nd, Eu, Gd, Tb, and Dy there are clear metamagnetic transitions at T=2.0 K for $H<55$ kOe. Strong anisotropies arising mostly from crystal electric field (CEF) effects were observed for most magnetic rare earths with $L\neq 0$. The experimentally estimated CEF parameters B$^2_0$ were calculated from the anisotropic paramagnetic $θ_{ab}$ and $ θ_{c}$ values and compared to theoretical trends across the rare earth series. The ordering temperatures as well as the polycrystalline averaged paramagnetic Curie-Weiss temperature, $θ_{ave}$, were extracted from magnetization and resistivity measurements, and compared to the de-Gennes factor.

description: Background Tobacco use is one of the major causes of morbidity and mortality. An intensive pharmacist-delivered smoking cessation program was implemented in eight primary care pharmacies in Qatar. Objective This study aimed to qualitatively explore the perspectives of pharmacists and patients regarding their experiences in the program and their recommendations for improving it. Setting Primary care in Doha, Qatar. Method This study used a qualitative case study approach with semi-structured interviews of a sample of patients and pharmacists who participated in the program. Interviews were conducted between October 2016 and June 2017, were audio-recorded and transcribed verbatim. A thematic approach for data analysis was used. Main outcome measures Perspectives of pharmacists and patients. Results Pharmacists who delivered the program (n = 17) and patients who completed the program’s outcomes assessment (n = 68) were invited through telephone call or email. Eight pharmacists and 22 patients were interviewed. Seven themes emerged: (1) both pharmacists and patients had positive experiences and both considered pharmacists as among the most suitable healthcare providers to provide smoking cessation interventions (2) both pharmacist and patient participants indicated that the program provided successful services (3) pharmacists identified several challenges for implementing the program including difficulty in motivating and in following-up patients, workplace barriers, communication and cultural barriers, (4) both pharmacists and patients perceived several barriers for quitting including lack of motivation to quit or to commit to the plan, high nicotine dependence, stress and personal problems (5) both pharmacists and patients considered several patient-related facilitators for quitting including development of smoking related complications, religious beliefs and external support; (6) use of smoking cessation medications was considered a program-related facilitator for quitting by patients whereas behavioral therapy was perceived to be a facilitator by pharmacists (7) pharmacists and patients proposed strategies for program improvement including enhancing pharmacist training and patient recruitment. Conclusion The program was perceived to be beneficial in helping patients quit smoking, and it positively contributed to advancing pharmacist role. The study findings can guide future development of successful pharmacist’ smoking cessation programs in Qatar.Other Information Published in: International Journal of Clinical Pharmacy

description: Combined in-situ PL and ex-situ SPV measurements were applied to optimize treatment times for wet-chemical etching processes for textured Silicon substrates. Applying smoothing procedures with extended HF treatment times, a definitive oxide removal was achieved. Two complementary strategies to enhance the electronic properties of (p)a-Si:H/(n)c-Si interfaces - wet-chemical substrate pre-treatment before a-Si:H deposition and the inclusion of intrinsic a-Si:H buffer layers - are discussed and their effect on the carrier lifetime, FF and open circuit voltage is explored. It was shown that the combination of special wet-chemical substrate pre-treatments and deposition of an intrinsic buffer layer at the a-Si:H/c-Si interface, shown previously to increase cell performance in (n)a-Si:H/(p)c-Si structures [1], can also be utilized to optimizes interface properties for the inverse structure, i.e. (p)a-Si:H/(n)c-Si hetero-junction solar cells.

description: This commentary outlines how the clinical pharmacist can support the safe administration of emergency medications in trauma anesthesia for seriously injured children. Promoting the professional development of the clinical pharmacist provided an opportunity to strengthen a key step in our trauma care pathway. We describe the implementation of this process in a new hospital, which was to become the designated children’s trauma center for an entire country. Although the literature documents the use of pharmacists in emergency intubation, ours was a unique set of circumstances, where empowering the pharmacist in frontline clinical care provided additional quality assurance for rapid sequence induction and intubation in trauma. Medical simulation was a core part of socializing the advanced clinical practice role of pharmacy within the trauma team. It was our experience that the pharmacist helps to promote confidence and decision making among other members of the trauma team.Other Information Published in: International Journal of Clinical Pharmacy

description: The new building integrated system of photovoltaic (BIPV) mobile modules has been developed in
order to maximise solar energy capture. Its main purpose is to optimize the usable area of roof and façades for
photovoltaic adaptation. The approach of this design is based on two principles: the daily trajectory of the sun, which
implies different orientations, and the intersection between architectural surfaces considered as an axis of rotation for
PV modules. This scientific innovation is the registered patent presented by the Universidad Politécnica de Madrid,
within the R&D programme for the US Department of Energy Solar Decathlon 2009 competition. The results of this
innovation will be integrated for the first time in the housing prototype, The B&W House, competing in Washington
in October this year. Nevertheless, the ultimate target is the commercial development, which will transform the
concept of dynamic energy efficient architecture.

description: Background Tobacco use is a leading preventable cause of morbidity and mortality globally. Clinical practice guidelines for the treatment of tobacco use dependence are of varied scope and quality, making it challenging for users to select and apply recommendations. Objective The study objective is to identify and critically appraise the quality of existing clinical practice guidelines for tobacco cessation. Setting The study occurred between collaborative academic institutions located in Qatar and New Zealand. Methods A systematic literature search was performed for the period 2006–2018 through the following databases: PubMed, EMBASE, CINAHL, ISI Web of Science, Scopus, National Guideline Clearing House, Campbell Library, Health System Evidence, Joanna Briggs Institute Evidence-Based Practice Database, Academic Search Complete, ProQuest, PROSPERO, and Google Scholar. Relevant professional societies’ and health agencies’ websites were also searched. Two reviewers independently extracted and assessed guidelines’ quality using Appraisal of Guidelines, Research and Evaluation II (AGREE II) instrument. Main outcome measure Standardized domain scores according to the AGREE II instrument. Results 7741 hits were identified. After removing duplicates and screening, 24 guidelines were included. Highest guideline quality was for National Institute for Health and Care Excellence (NICE) guideline with an overall ranking score of 87.56% and least quality was for Japanese Circulation Society Joint Working Group with an overall score of 29.34%.

description: Hybrid Renewable Energy Systems for the Supply of Services in Rural Settlements of
Mediterranean Partner Countries (HYRESS) project is supported by the European Commission’s 6th research
framework programme, under contract number 031994. Its strategic objective is to remove the knowledge barriers
against the installation of RE Systems. The ultimate objective of the project is to develop, combine, install, test and
assess the performance of low-cost pilot hybrid RE systems in remote areas of the Mediterranean. The main system
design criteria have been modularity, robustness, simplicity in use and the requirement of a very low maintenance.
Within HYRESS project, three pilot hybrid systems will be developed, installed, tested and evaluated (technically
and socially) in selected sites of Egypt, Morocco and Tunisia. ITER and ANME will be responsible for the microgrid
design and installation at Tunisia. The place chosen is the site of Ksar Ghilène, a village located in southern
Tunisia, in the governorate of Kébili at Bouflija depression.

description: There has been much recent interest in using metal (e.g. gold and silver) nanoparticles to enhance the
performance of photovoltaic solar cells. In this work the Finite Difference Time Domain method is used to find the forward
scattering (coupling) into silicon, of an incident electromagnetic field with wavelengths between 200nm and 800nm. In the
calculations spherical and hemispherical silver nano-particles are placed on the top surface of the silicon and using periodic
boundary conditions an infinite 2-dimensional array is considered. The results of the calculations show the effect of particle
size and array spacing on the forward scattering. When hemispherical particles are considered it is observed that the contact
area between the nanoparticle and silicon significantly reduces the forward scattering at most wavelengths.

PV Power Plants

description: 24th European Photovoltaic Solar Energy Conference, 21-25 September 2009, Hamburg, Germany; 4057-4060
description: The PV Power plant includes several serial and Ethernet protocol-based metering and
control equipment products from different vendors. The integration of those systems is a complex task and
the simplest modification or upgrade requires a lot of effort and time. Co-existence of various devices such
as inverters, charge controllers and data loggers in the laboratory resulted in the idea to construct one smart
device, able to collect all the metering data in one place. Integration is an essential requirement of
centralized control and monitoring. Additionally, easy access to metering data facilitates future data
processing and analyses. We are proposing an ARM9 Atmel microcontroller-based communication device
with 2.6.22 Linux® freeware kernel operating system for plant monitoring, remote diagnostics, data
acquisition and visualization. Assumptions made in development of the data logger are presented below.

description: We review the one-loop effective action in scalar QED and the Schwinger effect in a uniform electric field in a two-dimensional (anti-) de Sitter space. The Schwinger effect has a thermal interpretation in terms of the effective temperature introduced by Cai and Kim. We propose a method to find the density of states for the charged scalar and obtain the QED action density and the pair-production rate in the in-out formalism.

description: PEPITE (Study And Experimentation of Intermittent Energy Management using Electrochemical
Technologies) is a project endorsed by the French PAN-H research program (action plan on hydrogen and fuel cell)
supported by the ANR (French Research National Agency). This project concerns, among other tasks, a
demonstration of the electricity supply of a weather station with help of a PV/ H2 hybrid system in Cadarache (Aix in
Provence, 43°3152N 5°2714E, France). This paper describes the optimization method of the whole system sizing,
considering a predefined load profile, via observing his ability to meet the specifications taking into account the
appropriate constraints of the site. This approach has been made via a new numerical sizing code named ORIENTE
(Optimization of Renewable Intermittent Energies with hydrogeN for auTonomous Electrification) under Matlab
software.. The system is composed by a renewable source of energy (solar radiation with a PV array), an energy
storage system (H2 chain and battery pack) and converters which are associated to them. This article presents optimal
sizing curves for the PV/ H2 hybrid system in relation to the predefined load and the energy system balance for LLP =
0 (Loss of Load Probability). These results, determining the size of each subsystem (P ,V ,V ,P ,etc.) PV H2 O2 FC will
allow to build the best energy flows regulation mode.

description: PV Hybrid Systems are up to now individual solutions. This work presents a new approach to design
such systems significantly more flexible and compatible. A considerable consortium of German companies and
research institutes have developed this new step forward for PV Hybrid Systems. A strong separation between power
flow and information flow allows standardized components communication. All components are connected to a
standard bus. Through a standardized open source UESP protocol (Universal Energy Supply Protocol) a central
Energy Management Unit controls all components within the system. Through a virtual stock market the energy
management unit switches between several generators and controls the load. With the help of innovative UESP
system design and intelligent energy management strategies the overall performance and life time of PV Hybrid
Systems can be improved significantly. World-wide all manufacturers of components for PV Hybrid systems are
invited to participate in that open source communication standard.

description: Background Medication errors are a major public health concern that negatively impact patient safety and health outcomes. Effective and efficient medication error reporting systems and practices are imperative in reducing error incidence and severity. Objective The objectives were to quantify the incidence, nature and severity of medication errors, and to explore potential causality using a theoretical framework. Setting The study was conducted at Hamad Medical Corporation, the largest public funded academic healthcare center in the state of Qatar. Methods A retrospective review of medication error reports submitted to the Hamad Medical Corporation incident reporting system during 2015 to 2017. Data related to number of reports, reporter, medication, severity and outcomes were extracted. Reason’s Accident Causation Model was used as a theoretical framework for identifying potential causality. Two researchers independently categorized errors as: active failures (e.g. forgetting to administer medication at scheduled time); error provoking conditions (e.g. medication prescribed by an unauthorized physician and administered to the patient); and latent failures (e.g. organizational factors, lack of resources). Main outcome measures Incidence, classes of medications, reporter, error severity and outcomes, potential causality. Results A total of 5103 reports provided sufficient information to be included in the study giving an estimated error incidence of 0.044% of prescribed medication items. Most of the reports (91.5%, n = 4667) were submitted by pharmacists and majority (87.9%, n = 4485) were prescribing errors. The most commonly reported medications were anti-infectives for systemic use (22.0%, n = 1123) followed by medications to treat nervous system disorders (17.2%, n = 876). Only three errors reported to have caused temporary harm requiring intervention while one contributed to or resulted in temporary harm requiring initial or prolonged hospitalization. In terms of potential causality of medication errors, the majority (91.5%, n = 4671) were classified as active failures. Conclusion Almost all reports were submitted by pharmacists, indicating likely under-reporting affecting the actual incidence. Effort is required to increase the effectiveness and efficiency of the reporting system. The use of the theoretical framework allowed identification of potential causality, largely in relation to active failures, which can inform the basis of interventions to improve medication safety.Other Information Published in: International Journal of Clinical Pharmacy
