This special issueof Streamfocuses on positionality as an approach to researching issues in global communication. It is the result of an assignment that I crafted for a graduate course on Communication and Global Social Justice which is part of the School of Communication’s Global Communication MA Double Degree program. I have given this assignment for many years, and it has generated all manner of essays, but this spring—perhaps because geopolitics is in the air? —five of the papers addressed positionality in direct relationship to spatial-temporal considerations. This emergent set of papers has been brought together here as an exploration of how positionality shapes researchers’ engagements with translocal, transnational, geopolitical, networked or space-making processes.
Situationism and Performative Communication: The Counter-Conduct of Committed Indifference
Authors: Emond Veronique
Published: March 2021

Foucaultâ€™s notion of counter-conduct offers an interesting and challenging way to reimagine dissent. This essay briefly examines how certain kinds of dissent are uniquely challenging to systems and institutions because they are not easily subsumed by the system or its perceived (or traditional) contraries. An important example of this kind of dissent was, in the twentieth century, the Dada, Surrealist, and Situationist movements, which donâ€™t simply point (or conduct) people to a standard and easily imagined alternative to the prevailing hegemony, but seek to radically disrupt the way people see the world through different kinds of conduct which are fundamentally contrary to the prevailing order.

Authors:   Coastal Studies Institute , Louisiana State University, Baton Rouge, LA 70803, USA, Hsu Shih-Ang
Published: March 2021

In order to improve offshore wind power operation and maintenance (O&M), particularly during tropical and non-tropical cyclones, short-term forecasts or nowcasts up to 6 hours of meteorological and oceanographic (met-ocean) parameters including wind, waves, currents and turbulence intensity are needed. On the basis of numerous air-sea and wind-wave interaction experiments, datasets are analyzed including those from simultaneous measurements of wind and waves during Hurricane Wilma. Formulas are presented for nowcasts of met-ocean parameters. For quality assurance, these proposed formulas are further verified by independent datasets as provided in the literature. This manual-like guide should be useful for offshore wind-power O&M technicians and operators.
Patient Portal Use, Perceptions of Electronic Health Record Value, and Self-Rated Primary Care Quality Among Older Adults: Cross-sectional Survey
Authors: Cross Dori A , Levin Zachary , Raj Minakshi
Published: March 2021

Background

Older adults are increasingly accessing information and communicating using patient-facing portals available through their providers’ electronic health record (EHR). Most theories of technology acceptance and use suggest that patients’ overall satisfaction with care should be independent of their chosen level of portal engagement. However, achieving expected benefits of portal use depends on demonstrated support from providers to meet these expectations. This is especially true among older adults, who may require more guidance. However, little is known about whether misalignment of expectations around technology-facilitated care is associated with lower perceptions of care quality.

Objective

The aims of this study were to analyze whether older adults’ assessment of primary care quality differs across levels of patient portal engagement and whether perceptions of how well their provider uses the EHR to support care moderates this relationship.

Methods

We conducted a cross-sectional survey analysis of 158 older adults over the age of 65 (average age 71.4 years) across Michigan using a 13-measure composite of self-assessed health care quality. Portal use was categorized as none, moderate (use of 1-3 functionalities), or extensive (use of 4-7 functionalities). EHR value perception was measured by asking respondents how they felt their doctor’s EHR use improved the patient–provider relationship.

Results

Moderate portal users, compared to those who were extensive users, had lower estimated care quality (–0.214 on 4-point scale; P=.03). Differences between extensive portal users and nonportal users were not significant. Quality perception was only particularly low among moderate portal users with low EHR value perception; those with high EHR value perception rated quality similarly to other portal user groups.

Conclusions

Older adults who are moderate portal users are the least satisfied with their care, and the most sensitive to perceptions of how well their provider uses the EHR to support the relationship. Encouraging portal use without compromising perceptions of quality requires thinking beyond patient-focused education. Achieving value from use of patient-facing technologies with older adults is contingent upon matched organizational investments that support technology-enabled care delivery. Providers and staff need policies and practices that demonstrate technology adeptness. Older adults may need more tailored signaling and accommodation for technology to be maximally impactful.
Remote Heart Rhythm Monitoring by Photoplethysmography-Based Smartphone Technology After Cardiac Surgery: Prospective Observational Study
Authors: Lamberigts Marie , Van Hoof Lucas , Proesmans Tine , Vandervoort Pieter , Grieten Lars , Haemers Peter , Rega Filip
Published: March 2021

Background

Atrial fibrillation (AF) is the most common arrhythmia after cardiac surgery, yet the precise incidence and significance of arrhythmias after discharge home need to be better defined. Photoplethysmography (PPG)-based smartphone apps are promising tools to enable early detection and follow-up of arrhythmias.

Objective

By using a PPG-based smartphone app, we aimed to gain more insight into the prevalence of AF and other rhythm-related complications upon discharge home after cardiac surgery and evaluate the implementation of this app into routine clinical care.

Methods

In this prospective, single-center trial, patients recovering from cardiac surgery were asked to register their heart rhythm 3 times daily using a Food and Drug Administration–approved PPG-based app, for either 30 or 60 days after discharge home. Patients with permanent AF or a permanent pacemaker were excluded.

Results

We included 24 patients (mean age 60.2 years, SD 12 years; 15/23, 65% male) who underwent coronary artery bypass grafting and/or valve surgery. During hospitalization, 39% (9/23) experienced postoperative AF. After discharge, the PPG app reported AF or atrial flutter in 5 patients. While the app notified flutter in 1 patient, this was a false positive, as electrocardiogram revealed a 2nd-degree, 2:1 atrioventricular block necessitating a permanent pacemaker. AF was confirmed in 4 patients (4/23, 17%) and interestingly, was associated with an underlying postoperative complication in 2 participants (pneumonia n=1, pericardial tamponade n=1). A significant increase in the proportion of measurements indicating sinus rhythm was observed when comparing the first to the second month of follow-up (P<.001). In the second month of follow-up, compliance was significantly lower with 2.2 (SD 0.7) measurements per day versus 3.0 (SD 0.8) measurements per day in the first month (P=.002). The majority of participants (17/23, 74%), as well as the surveyed primary care physicians, experienced positive value by using the app as they felt more involved in the postoperative rehabilitation.

Conclusions

Implementation of smartphone-based PPG technology enables detection of AF and other rhythm-related complications after cardiac surgery. An association between AF detection and an underlying complication was found in 2 patients. Therefore, smartphone-based PPG technology may supplement rehabilitation after cardiac surgery by acting as a sentinel for underlying complications, rhythm-related or otherwise.

Authors: Chu Cherry , Cram Peter , Pang Andrea , Stamenova Vess , Tadrous Mina , Bhatia R Sacha
Published: March 2021

Background

The COVID-19 pandemic has led to a notable increase in telemedicine adoption. However, the impact of the pandemic on telemedicine use at a population level in rural and remote settings remains unclear.

Objective

This study aimed to evaluate changes in the rate of telemedicine use among rural populations and identify patient characteristics associated with telemedicine use prior to and during the pandemic.

Methods

We conducted a repeated cross-sectional study on all monthly and quarterly rural telemedicine visits from January 2012 to June 2020, using administrative data from Ontario, Canada. We compared the changes in telemedicine use among residents of rural and urban regions of Ontario prior to and during the pandemic.

Results

Before the pandemic, telemedicine use was steadily low in 2012-2019 for both rural and urban populations but slightly higher overall for rural patients (11 visits per 1000 patients vs 7 visits per 1000 patients in December 2019, P<.001). The rate of telemedicine visits among rural patients significantly increased to 147 visits per 1000 patients in June 2020. A similar but steeper increase (P=.15) was observed among urban patients (220 visits per 1000 urban patients). Telemedicine use increased across all age groups, with the highest rates reported among older adults aged ≥65 years (77 visits per 100 patients in 2020). The proportions of patients with at least 1 telemedicine visit were similar across the adult age groups (n=82,246/290,401, 28.3% for patients aged 18-49 years, n=79,339/290,401, 27.3% for patients aged 50-64 years, and n=80,833/290,401, 27.8% for patients aged 65-79 years), but lower among younger patients <18 years (n=23,699/290,401, 8.2%) and older patients ≥80 years (n=24,284/290,401, 8.4%) in 2020 (P<.001). There were more female users than male users of telemedicine (n=158,643/290,401, 54.6% vs n=131,758/290,401, 45.4%, respectively, in 2020; P<.001). There was a significantly higher proportion of telemedicine users residing in relatively less rural than in more rural regions (n=261,814/290,401, 90.2% vs n=28,587/290,401, 9.8%, respectively, in 2020; P<.001).

Conclusions

Telemedicine adoption increased in rural and remote areas during the COVID-19 pandemic, but its use increased in urban and less rural populations. Future studies should investigate the potential barriers to telemedicine use among rural patients and the impact of rural telemedicine on patient health care utilization and outcomes.
Harnessing Artificial Intelligence for Health Message Generation: The Folic Acid Message Engine (Preprint)
Authors: Schmälzle Ralf , Wilcox Shelby
Published: March 2021

BACKGROUND

Communication campaigns using social media can raise public awareness; however, they are difficult to sustain. A barrier is the need to generate and constantly post novel but on-topic messages, which creates a resource-intensive bottleneck.

OBJECTIVE

In this study, we aim to harness the latest advances in artificial intelligence (AI) to build a pilot system that can generate many candidate messages, which could be used for a campaign to suggest novel, on-topic candidate messages. The issue of folic acid, a B-vitamin that helps prevent major birth defects, serves as an example; however, the system can work with other issues that could benefit from higher levels of public awareness.

METHODS

We used the Generative Pretrained Transformer-2 architecture, a machine learning model trained on a large natural language corpus, and fine-tuned it using a data set of autodownloaded tweets about #folicacid. The fine-tuned model was then used as a message engine, that is, to create new messages about this topic. We conducted a web-based study to gauge how human raters evaluate AI-generated tweet messages compared with original, human-crafted messages.

RESULTS

We found that the Folic Acid Message Engine can easily create several hundreds of new messages that appear natural to humans. Web-based raters evaluated the clarity and quality of a human-curated sample of AI-generated messages as on par with human-generated ones. Overall, these results showed that it is feasible to use such a message engine to suggest messages for web-based campaigns that focus on promoting awareness.

CONCLUSIONS

The message engine can serve as a starting point for more sophisticated AI-guided message creation systems for health communication. Beyond the practical potential of such systems for campaigns in the age of social media, they also hold great scientific potential for the quantitative analysis of message characteristics that promote successful communication. We discuss future developments and obvious ethical challenges that need to be addressed as AI technologies for health persuasion enter the stage.

Experience of and Worry About Discrimination, Social Media Use, and Depression Among Asians in the United States During the COVID-19 Pandemic: Cross-sectional Survey Study (Preprint)
Authors: Pan Shuya , Yang Chia-chen , Tsai Jiun-Yi , Dong Chenyu
Published: March 2021

BACKGROUND

The COVID-19 outbreak has spurred increasing anti-Asian racism and xenophobia in the United States, which might be detrimental to the psychological well-being of Asian people living in the United States.

OBJECTIVE

We studied three discrimination-related variables, including (1) experience of discrimination, (2) worry about discrimination, and (3) racism-related social media use during the COVID-19 pandemic among Asians in the United States. We examined how these three variables were related to depression, and how the association between racism-related social media use and depression was moderated by personal experience of and worry about racial discrimination.

METHODS

A web-based, cross-sectional survey was conducted. A total of 209 people (mean age 33.69, SD 11.31 years; 96/209, 45.93% female) who identified themselves as Asian and resided in the United States were included in the study.

RESULTS

Experience of discrimination (β=.33, P=.001) and racism-related social media use (β=.14, P=.045) were positively associated with depressive symptoms. Worry about discrimination (β=.13, P=.14) was not associated with depression. Worry about discrimination moderated the relationship between racism-related social media use and depression (β=–.25, P=.003) such that a positive relationship was observed among those who had low and medium levels of worry.

CONCLUSIONS

The present study provided preliminary evidence that experience of discrimination during the COVID-19 pandemic was a risk factor of depressive symptoms among Asian people in the United States. Meanwhile, racism-related social media use was found to be negatively associated with the well-being of US Asians, and the relationship between social media use and depression was significantly moderated by worry about discrimination. It is critical to develop accessible programs to help US Asians cope with racial discrimination both in real lives and on social media during this unprecedented health crisis, especially among those who have not been mentally prepared for such challenges.
Book Review
Authors: Cahyo Edi Ashari
Published: March 2021

In Participation Without Democracy, Garry Rodan argues that as a response to the dynamics and contradiction inherent in the capitalist development, the regime—representing the dominant coalition of interest, the ruling/dominant political elites—‘invent’ ways to contain conflicts with societal entities (i.e., opposition parties, civil societies, labor unions) in a way so that such conflicts do not yield politically harmful impacts. 

This argument is based on two propositions. First, the development of capitalism has caused inequality to deepen. Both the ruling political-economy elites and the marginal groups found this inherent inequality and disruption in capitalism created political challenges, which, as a consequence, demand mitigation strategies. Second, the established coalition of interest's tactics handle political dissents towards the regimes move beyond the binary scenarios, not just merely opening political participation or applying coercion means such as crackdown and arrest. Instead, while the elites design the participation and representation institutions as a response to domesticating dissents and conflicts, the marginal groups also respond to those channels beyond being co-opted or merely refuse to join it. Opposition parties, radical NGOs, marginal groups seek to utilize the institutions for their transformative agenda. In short, both the ruling elites and the marginal groups have been engaged in the participating institutions with different goals in mind.
A REVIEW ON RECENT ADVANCEMENT IN PULSATILE DRUG DELIVERY SYSTEMS
Authors: THAKUR GAURAV , WANI SHAHID UD DIN , GAUTAM SURYA PRAKASH
Published: March 2021

Delivery systems with a pulsatile-release method are particularly involved in designing medicines for which traditional managed drug-release systems with the continuous release are not suitable. This medication also has a high first-pass impact or special conditions for chrono-pharmacology. These medications also have a high first-pass or unique chronopharmacological effect. The pulsatile release profile is characterised by a duration of no release (lag time) followed by a fast and full release of the drug. Pulsatile drug delivery systems may be classified into site-specific systems in which the drug is released inside the gastrointestinal system (e. g. colon) or time-controlled devices wherein the drug is released after a well-defined time period. Site-regulated release is typically controlled by environmental factors, such as pH or enzymes found in the intestinal tract, whereas drug release from time-controlled processes is controlled mainly by the delivery system and, preferably, not by the environment. This review covers various single-and multiple-unit oral pulsatile drug-delivery systems with an emphasis on time-controlled drug-release systems.

Authors: GHOLVE RANJEETA , SHEP DHANESHWAR , GADE PRAKASHCHANDRA , RAMAVAT MANISH
Published: March 2021

Objective: To study the effect of Cimetidine (H2 receptor antagonist) in combination with Glipizide (Sulfonylurea) on the blood sugar level in rabbits.

Methods: Six albino rabbits were taken for the study. Glipizide was administrated to each rabbit as a single drug therapy on day 1 and it was co-administrated with Cimetidine to each rabbit as a combinational drug therapy on day 7. Cimetidine was administrated to each rabbit from day 2 to day 6 as single drug therapy. Blood sugar levels were estimated on day 1 and on day 7 at 0, 1, 2, 4, and 6 h.

Results: The mean blood sugar level readings at 0, 1, 2, 4 and 6 h on day 1 were 90.4, 69.4, 62.9 and 65.7 mg% and on day 7 were 89.4, 74.8, 65.5, 56.4 and 61.2 mg % respectively. When mean blood sugar level on day 1 and day 7 was considered, there was a significant reduction in blood sugar level at 1, 2, 4 and 6 h and there was no significant fall in blood sugar level at 0 hour after co-administration of Glipizide and Cimetidine.

Conclusion: Cimetidine, when co-administered with Glipizide, significantly increases the hypoglycaemic action of Glipizide.

Published: March 2021

Objective: The present study was designed to assess HRQoL and depression among patients of liver cirrhosis in Pakistan.

Methods: A descriptive cross-sectional study design was used to assess health-related quality of life and depression among liver cirrhosis patients in Pakistan. Two pre-validated questionnaires i.e. SF 36 and HADS were self-administered to a sample of 382 cirrhotic patient’s selected using convenience sampling technique for measuring HRQoL and depression, respectively. After data collection, data was cleaned, coded and analyzed using in SPSS version 21.

Results: The results highlighted that lowest scores for HRQoL were observed in the domain of role physical (40.02,±24.01) followed by role emotional (41.93,±26.99) whereas the highest scores were observed in the domain of physical functioning (51.87,±15.22).

Conclusion: The results of the present study concluded that liver cirrhosis patients in Pakistan had poor HRQoL across all domains along with mild to moderate depression. While all domains were affected, the greatest impact was on role limitation due to physical as well as emotional problems. The most affected group among patients were females and patients having age greater than 60 y. Besides this severity and advanced stage of cirrhosis had a negative effect on all domains of HRQoL. Presence of complications further reduced HRQoL and increased depressive symptoms among liver cirrhosis patients.

Authors: TINRAT SIRIKHWAN
Published: March 2021

Objective: To screen phytochemical compounds and study antioxidant and antimicrobial activities of Pluchea indica (L.) Less (PI) leaves extracts for assessment the moisturizing lotion bar formulation containing it’s as a bioactive ingredient.

Methods: PI leaves were extracted in different solvents. Crude extracts were screened phytochemical compounds and evaluated antioxidant and antimicrobial activities before formulating to antibacterial moisturizing lotion bar.

Results: 95% ethanolic extract displayed high antioxidant activities. DPPH radical scavenging capacity with IC50 was 6.80±0.04 mg/ml (61.37±0.41%) and the ferric reducing ability power was 381.20±0.10 mg AAE/100 gDW. Additionally, 95% ethanolic extract served as a broad spectrum bacteriostatic agents against gram-positive and gram-negative species with an inhibition zone of 6.50±0.00-46.67±0.58 mm. It also was simultaneously as a broad spectrum bactericidal agents (MIC and MBC value of 25-200 mg/ml) by broth micro-dilution method. The screened phytochemical constituents (saponins, tannins, flavonoids, terpenoids, steroids, and alkaloids) in PI leaves extract may be responsible for high biological activities. Thus, 95% ethanolic extract was the most appropriate bioactive ingredient for formulated the product development.

Conclusion: The developed moisturizing lotion bar with 0.0041% of 95% ethanolic extract was the most eligible formula that showed good appearance, odor, color, homogeneity, after feel and stability. This extract-containing lotion bar formulation achieved a high level of customer satisfaction by sensory evaluation and development of this specific formulation should be subject to further clinical investigation.

Authors: VALAPARLA GEETHA RANI , MADDI PRANEETHA , VAKA KALYAN BABU
Published: March 2021

Objective: Diabetes is a complex heterogeneous disorder with chronic multiple illness which needs continuous medical management. Along with the medication life style modifications (diet, exercise) and patient self-management education is necessary not only for glyceamic control but also for prevention and delay of acute and long term complications. In this regard an observational study was carried out among 167 type 2 diabetic patients using a self-administered questionnaire in tertiary care hospital, Guntur.

Methods: Patients of both genders in the age of 30-89 with co morbidities were included in the study. Data regarding social habits, medication and adherence, duration of diabetes, co-morbidities, presence of diabetic complications along with the prevalence of complications while practicing regular diet, exercise with medical adherence was collected and evaluated.

Results: Among 167 patients 64.64 % were male and 35.36% were female. 14.4% of the populations are with diabetes from more than 17years. 65.3% of the patients don’t have alcoholic and smoking habit. Only 51.5% of the population was adherent to the medications. Hypertension is major co-morbidity existing among them. 82% of the study population reported macro vascular complication. The periodic prevalence rate(1-5years) of complications in type 2 diabetic patients who are adherent to medications and life style modifications was found to be 11.4% and the periodic prevalence rate of complications in patients who are either non-adherent to medications or life style modifications was 88.6%.

Conclusion: Medical and life style adherence is strongly recommended which also must be promoted by conducting awareness programme and health care camps with continuous supervision by the family members over patients for healthy society.

Authors: MORRISSEY HANA , ARIKAWE OLUTAYO , PAUL PAMELA , SANDHU MANJINDER , SADIQUE ZAIN , BALL PATRICK
Published: March 2021

Objective: Studies have shown that mental health is affected by poor physical health, with people living in the deprived area are the most affected. Community Pharmacists potentially have a new role in supporting people with mental illness and dementia to manage their medications. The aim of this local audit was to compare the local population to the national and global population, to inform the development and provision of local pharmacy mental health screening services, to support patients diagnosed with long-term conditions.

Methods: This project was designed as an audit of anonymised local data, to inform the development of services offered by community pharmacies to improve adherence to therapy amongst patients diagnosed with long-term conditions in the Black Country, UK. It forms part of a larger study granted ethical approval by the Health Research Authority in 2018. It was carried out against the background of the Covid-19 epidemic. A total of 652 patients pharmacy records were reviewed between March and April 2020. No patient identifiers were included in the reviewed data.

Results: This means that the results of this analysis might not be applicable to the entire local population outside the 31-90 y of age range.

Conclusion: It is was demonstrated during COVID-19 that pharmacists are well-positioned as easily accessible health care facilities to support patients, especially when the other NHS facilities are stretched or closed. Community pharmacies are in a position to offer large-scale screening programs such as self-completed anxiety, depression and cognitive function screening surveys and refer to general practitioners for further investigations. It is also recommended that the New Medicines Service include mental health disorder patients prescribed pharmacological therapy and to allow the pharmacists appropriate access to medical records to facilitate safe, integrated and effective patient care.

Considerações sobre as condenações injustas fundamentadas em provas periciais: análise do Innocence Project, do National Registry of Exoneration e mecanismos para redução de erros periciais
Authors: Lourenço Aline De Araújo , Silva Erick Simões da Camara e
Published: March 2021

Este artigo pretende analisar a relação entre as provas periciais e as condenações injustas. Trata-se de tema ainda pouco explorado no Brasil, mas com amplo debate nos EUA. Por essa razão, utiliza-se como base o modelo estadunidense para responder às seguintes questões: 1) Quais são as principais organizações e bases de dados estadunidenses relacionadas às reversões de condenações injustas? 2) Quais os reflexos da abordagem estadunidense no Reino Unido, no Canadá e no Brasil? 3) Como as provas periciais relacionam-se às condenações injustas? 4) Existem critérios aplicáveis às provas periciais que possam ser implantados no Brasil com vistas a diminuir a chance de erros periciais e interpretações equivocadas por parte dos julgadores? Espera-se apresentar o ponto e o contraponto no uso da prova pericial, abordar o mérito de organizações que buscam reverter condenações injustas e sugerir critérios para aprimorar a forma como os peritos dialogam com os julgadores.
Crisis familiares normativas
Authors: Lovo Javier
Published: March 2021

La familia es una institución social dinámica que sufre múltiples cambios durante su evolución, muchos de los cuales se consideran crisis porque ponen a prueba los recursos de adaptación del grupo familiar. Para un estudio adecuado, estas crisis se han clasificado en dos grandes grupos: las normativas o esperadas en la familia y las paranormativas que son accidentales. Eventos como el matrimonio, el nacimiento del primer hijo, la edad escolar, la adolescencia, el abandono del primer hijo del hogar, el envejecimiento, la jubilación y la muerte de los cónyuges, se consideran crisis normativas porque todas las familias deben confrontarlas. Se debe valorar que, aun siendo normativas, tienen el potencial para generar serios trastornos en la familia, ante lo cual es medular para la atención integral su comprensión y abordaje por parte del médico de familia.

PROJECT-BASED MATHEMATICS LEARNING: FRUIT SALAD RECIPES IN JUNIOR HIGH SCHOOL
Authors: Rahayu Poppy Trianti , Putri Ratu Ilma Indra
Published: March 2021

Mathematics learning is associated with 21st-century skills such as communication, collaboration, critical thinking in problem-solving, creativity, and innovation. To help students obtain these skills, a learning project was developed through Pendidikan Matematika Realistik Indonesia (PMRI) approach by using fruit salad recipes and collaborative learning based on the Lesson Study for Learning Community (LSLC) system. The primary purpose of this study was to develop fruit salad recipes to assist junior high school students in solving problems using mean, social arithmetic, and data presentation. It employed design research type validation studies using photos, fruit salad products, and document reviews as data collection techniques. The research subjects were 27 students of grade 8 from a junior high school in Palembang. This study resulted in a learning trajectory consisting of two activities and post-test questions. In the first activity, the students can analyze and solve problems in planning fruit salad recipes with material averaging, social arithmetic, and data presentation. In the second activity, the students can make fruit salads and write recipes based on skills to make fruit salad products. The results of this study demonstrate that in project-based learning through PMRI with the context of fruit salad recipes and the LSLC system, students can learn collaboratively. The learning helps them solve problems by using average material, social arithmetic, and data presentation in developing fruit salad recipes.
Sampling methods for investment portfolio formulation procedure at increased market volatility
Authors:   Department of Applied Mathematics, Dzicher Mateusz ,   College of Finance,   University of Economics in Katowice, Poland
Published: March 2021

Aim/purpose – In this paper, a market volatility-robust portfolio composition frame- work under the modified Markowitz’s approach with the use of sampling methods is developed in order to improve the allocation efficiency for a portfolio of financial in- struments formulation procedure at an increased market volatility. Design/methodology/approach – In order to overcome the risk of not receiving an optimal solution to the portfolio optimization (suboptimal outcomes of attribution of weights in allocation procedures) the developed model, first, implements the rationale that financial markets largely feature two states, i.e., quiescent (non-crisis; low market volatility) periods that are occasionally interspersed with stress (crisis; high market volatility) periods and, second, relies on many input samples of rates of return, either from an empirical distribution or a theoretical distribution (mitigating estimation risk). All computational results are reported for publicly available historical daily data sets on selected Polish blue-chip securities. Findings – Not only did the presented method produce more diversified allocation, but also successfully minimized the unfavorable effects of increased market volatility by providing less risky portfolios in comparison to Newton’s method, typically used for optimization under portfolio theory. Research implications/limitations – The research emphasized that in order to get a more diversified investment portfolio it is crucial to outdo the limitations of a single sample approach (utilized in Markowitz’s model) which may on some occasions be statistically biased. Thus it was proved that sampling methods allow to obtain a less concentrated and volatile allocation which contributes the investment decision-making. However, the current research focused solely on publicly available input data of particular securities. In this manner, an additional analysis can be prepared for other jurisdictions and asset classes. There can also be considered a use of other than variance risk measures. Originality/value/contribution – The suggested framework contributes to existing methods a wide array of quantitative data analysis and simulation tools for composing an unique approach that directly addresses the task of minimizing the adverse implications of increased market volatility that, in consequence, pertains to knowledgeable attributing of investment portfolio proportions of either individual or institutional investors. The prepared method is also proved to hold demanded computational quality and, importantly, the capacity for further development. Keywords: investment decisions, optimization techniques, portfolio selection, statistical simulation methods. JEL Classification: C150, C610, G110.
A mediation analysis: Board of directors’ composition, R&D investment, and international firm performance
Authors: Zouari-Hadiji Rim , Zouari Ghazi
Published: March 2021

The comprehension and the explanation of the research and development (R&D) investment behaviour are done within the framework of a reflection on corporate governance. This investment does not contribute to creating value only if it is framed by governance mechanisms which role is to keep organizational, agency, or transaction costs as low as possible. In this context, we try to determine whether an integrating model exists; one that measures the simultaneous effect of the characteristics of the board of directors on R&D and the firm performance in an international context. Our model seeks to identify whether the dominance of inside directors and the dual structure influence the level of R&D investment, the mediating variable, and hence the firm performance. Our empirical study was carried out on a total sample of 509 firms divided between 165 American firms, 173 Japanese firms, and 171 French firms over the period 2014 to 2019. The findings of the mediation analysis according to the approach of Preacher and Hayes (2004, 2008) show the significant role of mediation by R&D investment between, on the one hand, the dominance of inside directors and duality, and on the other hand, the firm performance. Differences in the configuration of board of directors (BD) in different countries thus lead to different attitudes to the fulfillment of the control task and the R&D investment decision, value creator
