Published: March 2023

Abstract
In this paper, we introduce a novel strategy to robustly diagnose the onset and demise of the rainy season using daily observed rainfall over seven specific regions across Australia, as demarcated by the Natural Resource Management (NRM) agency of Australia. The methodology lies in developing an ensemble spread of the diagnosed onset and demise from randomly perturbing the observed daily time series of rainfall at synoptic scales to obtain a measure of the uncertainty of the diagnosis. Our results indicate that the spread of the ensemble in the diagnosis of the onset and demise dates of the rainy season is higher in the subtropical region than the tropical region. Secular change of earlier onset, later demise, longer length, and wetter season are also identified in many of these regions. The influence of the PDO at decadal scale, ENSO and Indian Ocean dipole at interannual scale, and MJO at intraseasonal scale also reveals significant influence on the evolution of the rainy season over these regions in Australia. Most important, the covariability of the onset date with the length of the season and seasonal rainfall anomaly of the season is highlighted as a valuable relationship that can be exploited for real-time monitoring and providing an outlook of the forthcoming rainy season, which could serve some of the NRM regions.

Significance Statement
We document the rainfall variability during the rainy season over tropical, subtropical, and semiarid regions of Australia and relate them to modes of climate variability spanning from intraseasonal to secular time scales. The study highlights the varied influence of the modes of climate variability on various aspects of the evolution of the rainy season, such as its onset and demise dates and the seasonal rainfall anomaly over these Australian regions. The study uses 114 years of data and shows that the variations in the length of the rainy season and its seasonal rainfall anomaly are strongly dictated by variations of rainy-season onset date. This provides a quick seasonal outlook of the forthcoming rainy season by just monitoring the onset-date evolution in these regions.
User Experiences of Well-Being Chatbots
Authors: Kettle Liam , Lee Yi-Ching 
Published: March 2023

Objective The current paper conducted two parallel studies to explore user experiences of well-being conversational agents (CAs) and identify important features for engagement. Background Students transitioning into university life take on greater responsibility, yet tend to sacrifice healthy behaviors to strive for academic and financial gain. Additionally, students faced an unprecedented pandemic, leading to remote courses and reduced access to healthcare services. One tool designed to improve healthcare accessibility is well-being CAs. CAs have addressed mental health support in the general population but have yet to address physical well-being support and accessibility to those in disadvantaged socio-economic backgrounds where healthcare access is further limited. Method Study One comprised a thematic analysis of mental health applications featuring CAs from the public forum, Reddit. Study Two explored emerging usability themes of an SMS-based CA designed to improve accessibility to well-being services alongside a commercially available CA, Woebot. Results Study One identified several themes, including accessibility and availability, communication style, and anthropomorphism as important features. Study Two identified themes such as user response modality, perceived CA role, question specificity, and conversation flow control as critical for user engagement. Conclusion Various themes emerged from individuals’ experiences regarding CA features, functionality, and responses. The mixed experiences relevant to the communication and conversational styles between the CA and the user suggest varied motivations for using CAs for mental and physical well-being. Application Practical recommendations to encourage continued use include providing dynamic response modalities, anthropomorphizing the chatbot, and calibrating expectations early.
Foreign Capital Inflow, Exportability and the Indian Economy
Authors: Maiti Dibyendu , Singh Prakash 
Published: March 2023

The article investigated the effect of foreign direct investment (FDI) on Indian exports using aggregate and disaggregate data to capture macro- and micro-channels. India registers a steady rise in FDI during 1980–2018 in absolute terms but not in terms of GDP share. At the aggregate level, FDI is found to have significantly influenced Indian exports (both manufacturing and services) during 1980–2018 by suppressing its adverse effect on currency appreciation. Even at the firm-level analysis using the World Bank Enterprise Survey database, it is evident that higher participation of foreign ownership, a proxy of FDI measure, seems to have encouraged their export decisions. However, more than 50% of the capital inflows are received from two three countries which is also on limited service-related activities. The lower FDI share on manufacturing has limited the export rise. JEL Codes: F16, L11
A review of approaches and applications in building stock energy and indoor environment modelling

Published: March 2023

Current energy and climate policies are formulated and implemented to mitigate and adapt to climate change. To inform relevant building policies, two bottom-up building stock modelling approach: 1) archetype-based and 2) Building-by-building have been developed. This paper presents the main characteristics and applications of these two approaches and evaluates and compares their ability to support policy making. Because of lower data requirements and computational cost, archetype-based modelling approaches are still the mainstream approach to stock-level energy modelling, life cycle assessment, and indoor environmental quality assessment. Building-by-building approaches can better capture the heterogeneous characteristics of each building and are emerging due to the development of data acquisition and computational techniques. The model uncertainties exist in both models which may affect the reliability of outputs, while stochastic archetype models and timeless digital twin model have the potential to address the issue. System dynamics modelling approach can describe and address the dynamics and complexity of often-conflicting policies and achieve co-benefit of multiple policy objectives. This paper aims to provide comprehensive knowledge on building stock modelling for modellers and policymakers, so they could use a building stock model with an appropriate user interface without having to fully understand the underlying algorithms or complexities.

Background: Persistent instability of the knee is reported in up to 30% of patients after anterior cruciate ligament (ACL) reconstruction. Based on anatomic findings showing that ACL is a flat ribbon-like structure that twists during knee flexion, a new surgical ACL reconstruction technique using a ribbon-like graft has been developed. However the effect of this surgical technique on knee kinematics has not yet been evaluated. Purpose: To compare the anteroposterior and rotational stability of the knee after ACL reconstruction using single-bundle (SB) round and ribbon-like grafts in anterolateral-intact/deficient knees. Study Design: Controlled laboratory study. Methods: Twelve human fresh-frozen cadaveric knees were tested with a 6 degrees of freedom robotic system. Internal rotation and anterior translation of the knee were recorded from 0° to 90° of flexion. A full kinematic assessment was performed in each of the following conditions: (1) intact knee, (2) after sectioning of the ACL, (3) after ACL reconstruction using a SB hamstring tendon graft in a round configuration and a ribbon-like configuration, and (4) after sectioning of the anterolateral structures. One-way analysis of variance and post hoc Tukey tests were used for statistical analyses. Results: When compared with the intact knee, the ACL-deficient knee demonstrated a mean ± SD increase in anterior translation and internal rotation of 6.3 ± 2.5 mm ( P < .01) and 5.8°± 2.3° ( P < .01), respectively. After ACL reconstruction using a SB ribbon-like graft, the mean difference in anterior translation and internal rotation as compared with the intact knee was −0.1 ± 1.5 mm ( P = .842) and 0.0°± 1.1° ( P = .999). These differences from the intact knee were also not significant after ACL reconstruction using a round graft (−0.1 ± 1.3 mm, P = .999; −0.5°± 1.5°, P = .401). In the ACL-reconstructed knee using either a ribbon-like or round graft, sectioning of the anterolateral structures did not induce a significant increase of anterior translation and internal rotation of the knee. Conclusion: ACL reconstruction using a SB ribbon-like or round graft restored the kinematics of the intact knee at time zero. Secondary sectioning of the anterolateral structures in the ACL-reconstructed knee using both types of graft did not significantly affect the anterior translation and internal rotation of the knee. Clinical Relevance: This is the first biomechanical study on the new ACL reconstruction technique using a ribbon-like graft.

Published: March 2023

In this work, two D-A monomers 2,3-di(5-methylfuran-2-yl)-5,7-di(thiophene-2-yl) thiopheno[3,4-b] pyrazine (MFTTP) and 2,3-di(5-methylfuran-2-yl)-5,7-di(4-methoxythiophen-2-yl) thiopheno [3,4-b] pyrazine (MFMOTTP) were first obtained by Stille Coupling reaction, and then the corresponding composites were obtained by in-situ oxidative polymerization method with supercapacitor carbon. The surface morphology, chemical structure, and the element valence states of two materials were characterized by scanning electron microscopy, infrared and XPS, respectively. The specific surface areas of PMFTTP@SC and PMFMOTTP@SC are measured as 756.5 and 954.9 m2/g, respectively. The CV curves were used to determine the initial oxidative and initial reduction potentials, both polymers have a narrow band gap with Eg values below 1.5 eV, electron clouds in the HOMO and LUMO orbits of the polymer are mainly distributed on the aromatic rings of the polymer backbone. Polymer composite materials were used as the anode materials and the lithium sheets were used as counter electrode, and then lithium ion batteries are assembled. The first discharge specific capacities of PMFTTP@SC and PMFMOTTP@SC are 741.9 and 951.3 mAh/g at a current density of 100 mA/g, and as the electrodes are activated in the subsequent cycles, their coulomb efficiencies can reach more than 92% from the third cycle. In contrast, PMFMOTTP with methoxy-thiophene as the donor unit has higher conductivity and lower corresponding impedance due to its stronger electron donating ability and abundant pore structure, which is also more conducive to the lithiation/delithiation redox process.

Introduction Antineoplastic drugs (ADs) are commonly used pharmaceuticals for anticancer treatments. It has previously been shown that the external surface of drug vials frequently is contaminated with ADs. More than a decade ago methods to prevent occupational exposure were introduced by using plastic coverage of the glass vials or packing vials in a secondary plastic container. The aim of the pilot study was to determine contamination levels of ADs on different parts of AD packaging of two different commercially available drug vials on the Swedish market and to investigate the occurrence of cross contamination of ADs. Methods Packagings of gemcitabine (GEM) and 5-fluorouracil (5-FU) were tested by wipe sampling. Five ADs; GEM, 5-FU, cyclophosphamide (CP), ifosfamide and etoposide were quantified using liquid chromatography mass spectrometry. Results AD contaminations were detected in 69% and 60% of the GEM and 5-FU packaging samples. Highest levels, up to approximately 5  µg/sample, were observed on the glass vials. The protective shrink-wrap of 5-FU vials and the plastic container of GEM were contaminated with low levels of 5-FU and GEM, respectively, and furthermore the 5-FU vials with shrink-wrap were cross-contaminated with GEM. Cross-contamination of CP and GEM was detected on 5-FU vials with plastic shrink-wrap removed. Conclusions External contamination of ADs are still present at primary drug packagings on the Swedish market. Protection of AD vials by plastic shrink-wrap or a secondary plastic container does not remove the external contamination levels completely. The presence of cross contamination of ADs on drug packagings was also observed.
Emergency Nurses’ Care of Psychiatric Patients
Authors: Hennen Rebecca , Phillips Kathryn E. 
Published: March 2023

Objective: The volume of patients with mental illness presenting to the emergency department (ED) has been increasing in recent years, yet many ED nurses hold stigmatized attitudes and behaviors about patients with mental illness, creating barriers to therapeutic care. At the same time, there has been an increase in workplace violence (WPV) against nurses. Fortunately, resilience helps nurses manage their response to WPV and continue to provide therapeutic care. Although research has considered many barriers to the therapeutic care of patients with mental illness in the ED, the variables of stigma, resilience, and the experience of WPV have not been considered in relation to behavioral care competence and work performance, which is the purpose of this study. Methods: A survey consisting of the Brief Resilience Scale, the Individual Work Performance Questionnaire, the Behavioral Healthcare Competency (BHCC) survey, the Opening Minds Scale for Healthcare Providers, and open-ended questions about WPV were used to collect data. Independent t-tests were run between scale scores and categorical descriptive data. Correlations were run between scale scores and continuous descriptive data. Results: Over half (60%) had experienced a personal injury from WPV. Higher behavioral competence scores were associated with lower stigma and higher contextual work performance. Nurses who experienced a WPV injury had higher mean BHCC and higher contextual work performance scores. Conclusions: WPV may be an impetus for nurses to improve their practice in behavioral health and working as part of a team.

Published: March 2023

Introduction COVID-19 has led to delays in providing healthcare in both emergency and non-emergency settings, especially in surgical subspecialties which rely heavily on referrals and in-person visits. Without an established telehealth infrastructure, many otorhinolaryngological departments experienced decreases in consultations. Telemedicine has attempted to bridge the gap between pre- and post-pandemic periods by creating a safe avenue of communication between otorhinolaryngologists and patients. This review hopes to address the accuracy of telemedicine in patient diagnosis and management. Methods Searches were conducted since study conception until June 30, 2022, on multiple databases including PubMed, SCOPUS, and CINAHL for this systematic review and meta-analysis. Diagnostic accuracy, management accuracy, kappa, sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) were meta-analyzed by comparing virtual visits to in-person visits (gold standard). Results Nineteen studies were included in this review. A total of 1518 patients were included across all studies. When comparing virtual visits against in-person visits, accurate diagnosis was made in 86.2% [82.1,89.9, I2 = 73.5%, P < 0.0001] of patients and management accuracy was 91.5% [86.1,95.7, I2 = 81.8%, P < 0.0001] when treating patients. Kappa value determining interrater reliability was 0.8 [0.7,0.9, I2 = 81.8%, P < 0.0001]. Conclusion Our data suggest that diagnostic and management concordance is above 80% when comparing diagnosis and management strategies in patients who underwent both telehealth and in-person visits with an otorhinolaryngologist. In uncomplicated patients, telehealth might be a reliable source for diagnosis and management however, in-person consultation is likely still required for pathologies in which physical exam, imaging or procedural elements represent a vital component of the work-up.
Using modified intention-to-treat as a principal stratum estimator for failure to initiate treatment
Authors: Kahan Brennan C , White Ian R , Edwards Mark , Harhay Michael O 
Published: March 2023

Background: A common intercurrent event affecting many trials is when some participants do not begin their assigned treatment. For example, in a double-blind drug trial, some participants may not receive any dose of study medication. Many trials use a ‘modified intention-to-treat’ approach, whereby participants who do not initiate treatment are excluded from the analysis. However, it is not clear (a) the estimand being targeted by such an approach and (b) the assumptions necessary for such an approach to be unbiased. Methods: Using potential outcome notation, we demonstrate that a modified intention-to-treat analysis which excludes participants who do not begin treatment is estimating a principal stratum estimand (i.e. the treatment effect in the subpopulation of participants who would begin treatment, regardless of which arm they were assigned to). The modified intention-to-treat estimator is unbiased for the principal stratum estimand under the assumption that the intercurrent event is not affected by the assigned treatment arm, that is, participants who initiate treatment in one arm would also do so in the other arm (i.e. if someone began the intervention, they would also have begun the control, and vice versa). Results: We identify two key criteria in determining whether the modified intention-to-treat estimator is likely to be unbiased: first, we must be able to measure the participants in each treatment arm who experience the intercurrent event, and second, the assumption that treatment allocation will not affect whether the participant begins treatment must be reasonable. Most double-blind trials will satisfy these criteria, as the decision to start treatment cannot be influenced by the allocation, and we provide an example of an open-label trial where these criteria are likely to be satisfied as well, implying that a modified intention-to-treat analysis which excludes participants who do not begin treatment is an unbiased estimator for the principal stratum effect in these settings. We also give two examples where these criteria will not be satisfied (one comparing an active intervention vs usual care, where we cannot identify which usual care participants would have initiated the active intervention, and another comparing two active interventions in an unblinded manner, where knowledge of the assigned treatment arm may affect the participant’s choice to begin or not), implying that a modified intention-to-treat estimator will be biased in these settings. Conclusion: A modified intention-to-treat analysis which excludes participants who do not begin treatment can be an unbiased estimator for the principal stratum estimand. Our framework can help identify when the assumptions for unbiasedness are likely to hold, and thus whether modified intention-to-treat is appropriate or not.

Published: March 2023

Background: Percutaneous femoral derotational osteotomies are performed in both adult and pediatric patients. There is little published on the outcomes after femoral derotational osteotomy in pediatric patients. Methods: A retrospective cohort study of pediatric patients treated with percutaneous femoral derotational osteotomy by one of two surgeons between 2016 and 2022 was performed. Data collected included patient demographics; surgical indications; femoral version; tibial torsion; magnitude of rotational correction; complications; time to hardware removal; pre-operative and post-operative patient-reported outcome scores, including Limb Deformity–Scoliosis Research Society and Patient-Reported Outcomes Measurement Information System; and time to consolidation. Descriptive statistics were used to summarize the data and t tests used to compare means. Results: Thirty-one femoral derotational osteotomies in 19 patients were included with an average age of 14.7 (9–17) years. The average rotational correction was 21.5° ± 6.4° (10°–40°). The average length of follow-up was 17.9 ± 6.7 months. There were no instances of nonunion, joint stiffness, or nerve injury. No patients returned to the operating room for additional surgeries other than routine hardware removal. There were no cases of avascular necrosis of the femoral head. Of the 19 patients, 8 completed both a pre-operative and post-operative survey set. There were significant improvements in the Limb Deformity–Scoliosis Research Society Self-Image/Appearance sub-category and the Patient-Reported Outcomes Measurement Information System Physical Function sub-category. Conclusion: Femoral derotational osteotomy using a percutaneous drill hole technique with antegrade trochanteric entry femoral nail is safe in the pediatric population and improves self-image in patients with symptomatic femoral version abnormalities.
