Published: November 2023

Purpose: This study comparatively examines the impact of oil price shocks on five selected macroeconomic variables in two African oil-producing countries, Angola and Libya, using secondary data from 1983 to 2021.
Materials and Methods: We adopted a causal-comparative/Quasi-Experimental research design to infer cause-and-effect relationships. The structural vector error correction model (SVECM) was employed due to the advantage of cointegrated variables in both countries.
Findings: The empirical analysis reveals that the response to and significance of oil price shocks are somewhat similar in the two countries, with a significant positive and persistent effect on oil prices and real economic output. However, other macro variables responded insignificantly to oil price shocks, albeit with varying signs. Based on the empirical analysis, we conclude that while oil price shocks have a significant and lasting positive impact on oil prices and real economic output in both countries studied, their influence on other macroeconomic variables is relatively insignificant, though these variables exhibit varying responses. Hence, to mitigate the risks associated with oil price shocks and reduce dependency on oil revenues, we recommend that Angola and Libya diversify their economies by investing in non-oil sectors such as agriculture, manufacturing, tourism, and renewable energy.
Implications to Theory, Practice and Policy: Furthermore, we recommend the implementation of macroeconomic stabilization policies to reduce vulnerability to oil price shocks. Fiscal measures, such as establishing sovereign wealth funds to save excess oil revenues during high oil price periods, can stabilize the economy during low oil price periods. Monetary policies, including interest rate adjustments, can counteract inflationary or deflationary pressures resulting from oil price shocks.

Published: November 2023

Objectives: To compare the frequency of surgical site infections after abdominal surgery with and without intraoperative irrigation of the surgical wounds.
Methodology: This randomized controlled trial was performed in general surgery department, PAF Hospital, Islamabad from 10th August 2022 to 9th May 2023. A total of 520 patients undergoing abdominal surgeries of any gender between the ages of 15–70 years were included. Patients were randomly divided in two groups on the basis of non-probability, consecutive sampling. The participants included in the group-A did not receive any intraoperative wound irrigation. The participants in the Group-B received intraoperative wound irrigation with antiseptic solution i.e., povidone-iodine in solution. Each patient was followed up respectively on 7th, 21st and 30th days postoperatively to observe surgical site infection. Chi square test was applied to compare SSI percentage between two groups. P-value of less than 0.05 was taken as significant.
Results: Mean age was 39.87±6.93 years in group-A and 37.67±7.56 years in Group-B. Out of 520 patients, 344 (66.15%) were males and 176 (33.85%) were females. Surgical site infection after abdominal surgery without intraoperative irrigation was found to be 34 (13.08%) and surgical site infection after abdominal surgery with intraoperative irrigation was 12 (4.62%), hence statistically significant (p-value = 0.0007).
Conclusion: This study concluded that intraoperative wound irrigation is effective to prevent the surgical site infections after abdominal surgery.
Structural Optimisation and Behaviour of the Breakwater Integrated Oscillating Water Column Device

Published: November 2023

The Oscillating Water Column (OWC) device is a relatively young and underdeveloped technology for generating electricity from wave energy. Compared to other common renewable sources such as solar and wind energy, the costs for bottom-standing OWC’s are too high for the technology to be economically competitive. A first step in lowering the cost was the integration of OWC devices into breakwaters. Often, OWC are built quite robustly due to insufficient confidence in the magnitude of the extreme loads. This leaves room for optimisation, which so far has not been looked into in detail. In an attempt to lower the costs further, the possibilities for structural optimisation are investigated in this research. The U-OWC device in Civitavecchia, an OWC with an additional vertical duct, is used as a case study and is modelled in 3D in a one-way coupled hydraulic-structural numerical model. The model contained both a fluid domain, i.e. the wave tank, and a solid domain, i.e. the OWC structure. Coupling the two gives direct feedback on the wave impact in terms of a stress state in the structure. By converting the stresses to sectional forces, a new minimally required wall thickness can be found. Comparing these to the original thicknesses of the three main walls gives the optimisation potential of the OWC structure. Numerical simulations were carried out in operational and design conditions for varying geometries. Based on this, it was found the OWC walls could have been built using 35% less concrete on average. The results also led to a new insight on the structural behaviour. Clear trends were found in where and when to expect critical loads. It was also found that the geometrical changes barely had any influence on these properties. These findings were used to develop a new and simple design method, making a full structural analysis redundant. Removing the structural domain and making use of the found property that water pressures are constant over the transverse width, imply that a 2D model would be sufficient, reducing the model size drastically.
Estimating the Influence of Sea Level Rise and Climate Change on Coastal Defences in Western Taiwan

Published: November 2023

Situated in the Western Pacific Ocean, Taiwan is frequently affected by powerful typhoons. The present research evaluates the storm surges that could take place along the western coastline of Taiwan, and the design water level that will likely be required by coastal structures in the course of the 21st century to protect coastal settlements. To do so, the intensity of a given case study typhoon (Soudelor, which caused great damage to Taiwan in 2015) that could affect the target case study area (Yunlin county) was modified by taking into account climate change and sea level rise (SLR), by changing the sea surface temperature (SST), atmospheric air temperature (AAT), and relative humidity (RH) in an ensemble of 14 GCMs in CMIP5 according to RCP4.5 and RCP8.5, targeting the year 2041~2060 and 2081~2100 time horizons. The Advanced Research Weather Research and Forecasting Model (WRF-ARW) and the Unstructured Finite Volume Community Ocean Model (FVCOM) were utilized to simulate the typhoons and storm surges. The hindcasting of the historical typhoon showed good agreement with the observed data provided by the Central Weather Bureau (CWB) in Taiwan, and the simulations under future climate change scenarios forecasted an increase in typhoon intensity, especially the maximum wind speed. However, the storm surge simulations indicated a limited increase in storm surge height, and even a decrease when considering also SLR. Nevertheless, the estimated maximum water level, including both effect of SLR and future storm surge height, can increase up to 3.53 m and 3.84 m relative to mean sea level at the tidal stations in Yunlin and Chiayi County, respectively. The results showed that storm surges in the study area, characterized by a shallow bathymetry with many sandbars and land reclamation projects, are highly influenced by the change in water depth due to SLR and tidal changes, and the existence of the Central Mountain Range, which can greatly affect the accuracy of the simulated typhoon wind fields.
Feasibility of pumped hydro energy storage in a river cascade - case study of the Meuse
Authors: Lambach Jan Willem , Bricker Jeremy , Marence Miroslav 
Published: November 2023

The Meuse river in the Netherlands has been made navigable by the construction of a cascade of seven low head weirs. Because of environmental regulations, hydropower facilities exist at only two weirs. This implies the full hydropower potential of the Meuse cascade is not utilized. By using pump-turbines the river sections upstream of the weirs could be additionally usable as energy storage reservoirs and could improve and ensure river navigability under changed climate conditions.

The main goal of this study is to assess the possible utilization of the full energy storage- and hydropower potential of the Meuse cascade within Dutch environmental regulations. The novelty of this study is the evaluation of the concept of using canalized river sections for pumped-storage purposes within conditions of fluctuating discharge and -water levels throughout the year.

In order to meet the goal of the study the relatively fish-friendly Archimedean screw has been selected as pump-turbine. Next a conceptual design of a pumped-storage hydropower plant equipped with screws has been compiled. By using this design, the assessment of utilizing the hydropower- and energy storage potential of the cascade has been carried out by constructing and applying a numerical model.

The study shows it is possible to utilize the full hydropower- and the majority of the energy storage potential of the Meuse cascade. The cumulative installed turbine capacity for the cascade turns out to be 81 MW. The Annual Energy Yield (AEY) from regular hydropower alone is 225 GWh. In addition, the yearly surplus power that can be processed for energy storage purposes is 137.2 GWh, of which 77.2 GWh is returned to the grid by a round-trip efficiency of 56.25 %. In total 302.2 GWh can be delivered to the grid which can power up to 75.000 households. The specific cost is relatively high: roughly 15,000 euro/kW.

The method developed here can be applied to evaluate the storage- and hydropower potential of other canalized rivers as well, such as the upper Mississippi.
Elaboração de uma arquitetura semiocognitiva para a aprendizagem do olhar nas representações gráficas cartesianas
Authors: Das Neves Barbosa Thiago Henrique , Moretti Méricles Thadeu 
Published: November 2023

Aprender a olhar é um gesto intelectual fundamental na aprendizagem científica: o biólogo precisa compreender o que vê em microscópio; o físico em um gráfico que rege o movimento de um móvel; o leitor comum procura compreender um infográfico publicado em uma revista de grande circulação. Criada ainda no século XIV, o sistema de representação geométrico-cartesiano possui desdobramentos históricos no desenvolvimento da matemática, mostrou-se ser um instrumento de aprendizagem multidisciplinar. Na matemática, é tema específico de aprendizagem que não depende de aplicações práticas de outras disciplinas. A reta, enquanto objeto matemático, está presente em todo o itinerário formativo básico do estudante. Neste trabalho, apresentaremos um olhar sobre o estudo da reta, sob a perspectiva da Teoria de Registros de Representação Semiótica de Raymond Duval. Será também realizada uma análise qualitativa de uma atividade sobre este assunto, aplicada numa turma do terceiro ano do ensino técnico integrado ao ensino médio de um Instituto Federal situado em Santa Catarina. Serão apontadas funções discursivas e metadiscursivas relacionadas à resolução dos estudantes, assim como, as variáveis visuais e unidades simbólicas correspondentes indicadas pelos sujeitos nas atividades realizadas.

Leadership Development of Women of Color in Occupational Therapy: A Qualitative Intersectional Analysis
Authors: Nirmul Ushentha , Cabrejo Pamela Talero , Smith Cristina Reyes 
Published: November 2023

Abstract
Importance: Women of color hold social positions and group member identification in occupational therapy that differ from those of White majority women. Their experience with leadership acquisition warrants exploration of the complex social processes that shape their professional trajectory.
Objective: To understand which intersecting patterns of social identity categories have shaped the leadership development of women of color leaders in occupational therapy in the United States and how they do so.
Design: This study followed a qualitative multilevel intersectional approach.
Setting: Multiregional interviews were conducted by means of virtual technology.
Participants: Eight English-speaking women, self-identified as a leader and a woman of color living in the United States, were recruited by means of purposive, snowball sampling of women of color in leadership positions in occupational therapy.
Outcomes and Measures: An eight-step multilevel intersectional data analysis of participants’ narratives was used to identify emergent intersecting patterns of social identity categories in their leadership development.
Results: Participants’ predominant intersecting patterns converged into four themes: (1) early leadership development does not happen without access to opportunities, (2) sponsorship and mentorship have implications beyond one’s leadership development, (3) being seen is essential for leadership development, and (4) persevering is a constant state of struggle.
Conclusions and Relevance: Leadership development for women of color in occupational therapy thrives at the intersection of scholarship, mentorship, and authentic inclusion.
What This Article Adds: The study expands leadership inquiry in occupational therapy to include the perspectives of women of color and to better understand the patterns of social identity categories in leadership achievement.
Positionality Statement: The term women of color is a political designation coined in the 1970s by women in the minority to define solidarity with other oppressed women (Zavella, 2022). The term women of color is used to achieve a unified political voice to seek gender equality for women who feel unsupported by White feminist ideology (Zavella, 2022). Moreover, it describes multicultural and multiethnic solidarity among women who sit outside the structures of power and privilege and experience life at the intersection of gender and race. Thus, women of color include Black, Latinx, Asian, Pacific Islander, mixed-race women, and Native American women, including American Indian, Alaskan Native, and Native Hawaiian women (McKinsey & Company, 2022).

RELAÇÃO ENTRE TRANSTORNO DISMÓRFICO CORPORAL E NECESSIDADE DE TRATAMENTOS ESTÉTICOS: REVISÃO SISTEMÁTICA
Authors: Campos João Heli , Cutuli Carlos A 
Published: November 2023

Objetivo: destacar a relação entre o Transtorno Dismórfico Corporal (TDC) de alta prevalência e os procedimentos estéticos faciais por meio de uma revisão sistemática da literatura. Métodos: A busca nas bases PubMed, SciELO, ScienceDirect e BVS ocorreu em 19/08/2023. Foram usados os termos Mesh/Decs na PubMed, ScienceDirect e BVS/Medline: Body Dysmorphic Disorder, Aesthetic Procedures, Face e diagnosis. Na SciELO: Transtorno Dismórfico Corporal, Procedimentos Estéticos, Insatisfação Corporal, Imagem Corporal e Cirurgia Plástica. Na PubMed obtiveram-se 15 resultados, destes 6 foram eleitos. Na SciELO uma busca nos últimos 4 anos obteve 4 resultados, destes 3 foram eleitos. Na ScienceDirect nos últimos 10 anos para arquivos de acesso livre foram obtidos 47 resultados, destes foram eleitos 12. Na BVS obteve 35 resultados e 8 foram eleitos. Somando os registros eleitos resultou em 29 e por 8 registros aparecem em mais de uma base apenas 21 foram usados na síntese. Resultados: O lapso temporal entre os 21 artigos eleitos para síntese foi de 8 anos compreendendo artigos publicados entre 2016 e 2023. O número de participantes nos 21 registros foi de 3,163, cinco artigos (23,8%) não mencionaram o gênero dos participantes, quatro artigos (19%) o total dos participantes era do gênero feminino. A síntese mostrou que dentre as medidas usadas as mais frequentes foram os questionários ⁶BDD-YBOCS, ¹⁴BDDE e ¹⁴BDDE. A prevalência estimada de TDC na população geral foi entre 1% e 2,5%. A prevalência entre adolescentes é um pouco mais alta podendo chegar a 3,6%. Quatro dos artigos (19%) não fizeram menção quanto à prevalência na população geral e três deles apresentaram a prevalência estimada em adolescentes. Conclusão: os profissionais de estética devem estar cientes de que o TDC é uma contra-indicação à realização de tratamentos estéticos. Estes pacientes têm forte tendência de ocultar a natureza de seu desejo e se submetem a qualquer procedimento. A abordagem multidisciplinar pode instituir o diagnóstico precoce evitando insatisfação com o resultado, comportamentos violentos contra o profissional e ações judiciais. O diagnóstico e a terapêutica cabem aos profissionais da psicologia e psiquiatria.
