Electrospun nanofibers provide a good platform to treat chronic wounds like diabetic foot ulcers
Authors: Dowaidar Moataz
Published: June 2021

Chronic foot ulceration is one of the major comorbid challenges associated with the manifestation of Type-2 Diabetic Mellitus and is responsible for high mortality rates, requiring the development of a localized drug delivery system (DDS) that can deliver the drug payload while also facilitating wound closure. Although nanofibers may be produced in many ways, electrospinning is one of the most versatile methods. Nanofiber-based DDSs show a substantial influence on targeted drug delivery, faster wound healing, and chronic wound closure. Electrospun nanofibers have evolved over time from simple nanofibers to new generations of nanofibers such as blend, composite, core-shell electrospun, and hybrid nanofibers, each with unique physicochemical and mechanochemical properties, giving distinct advantages to the respective nanofibers for better diabetic wound management. Optimizing the parameters involved in the preparation of nanofibers, which can be classified as static, processing and environmental parameters, is critical for process reproducibility, ensuring the desired properties of nanofibers, maintaining uniformity and maximizing the performance of electrospinning. Electrospun nanofibers are a suitable platform for treating chronic wounds such as diabetic foot ulcers. However, clinically using nanofiber-based DDSs as a localized wound therapy platform requires comprehensive physicochemical and mechanochemical characterization, as well as rigorous in-vitro and in-vivo drug release and wound healing efficacy testing.
Bayesian population correlation: A probabilistic approach to inferring and comparing population distributions for detrital zircon ages
Authors: Tye Alexander , Wolf Aaron , Niemi Nathan
Published: June 2021

Populations of detrital zircons are shaped by geologic factors such as sediment transport, erosion mechanisms, and the zircon fertility of source areas. Zircon U-Pb age datasets are influenced both by these geologic factors and by the statistical effects of sampling. Such statistical effects introduce significant uncertainty into the inference of parent population age distributions from detrital zircon samples. This uncertainty must be accounted for in order to understand which features of sample age distributions are attributable to earth processes and which are sampling effects. Sampling effects are likely to be significant at a range of common detrital zircon sample sizes (particularly when n < 300).In order to more accurately account for the uncertainty in estimating parent population age distributions, we introduce a new method to infer probability model ensembles (PMEs) from detrital zircon samples. Each PME represents a set of the potential parent populations that are likely to have produced a given zircon age sample. PMEs form the basis of a new metric of correspondence between two detrital zircon samples, Bayesian Population Correlation (BPC), which is shown in a suite of numerical experiments to be unbiased with respect to sample size. BPC uncertainties can be directly estimated for a specific sample comparison, and BPC results conform to analytical predictions when comparing populations with known proportions of shared ages. We implement all of these features in a set of MATLAB® scripts made freely available as open-source code and as a standalone application. The robust uncertainties, lack of sample size bias, and predictability of BPC are desirable features that differentiate it from existing detrital zircon correspondence metrics. Additionally, analysis of other sample limited datasets with complex probability distributions may also benefit from our approach.
Ray of hope for sub-Saharan Africa's paratransit: solar charging of urban electric minibus taxis in South Africa
Authors: Abraham Chris , Rix Arnold , Ndibatya Innocent , Booysen MJ
Published: June 2021

Minibus taxi public transport is a seemingly chaotic phenomenon in the developing cities of the Global South with unique mobility and operational characteristics. Eventually this ubiquitous fleet of minibus taxis will have to transition to electric vehicles. This paper examines the impact of this inevitable evolution. We present a generic simulation environment to assess the grid impact and charging opportunities, given the unique paratransit mobility patterns. We used floating car data to assess the energy requirements of electric minibus taxis, which will have a knock-on effect on Africa's already fragile electrical grids. We used spatio-temporal and solar photovoltaic analyses to assess the informal and formal stops that would be needed for the taxis to recharge from solar PV in the region's abundant sunshine. The results showed energy demand from a median of 215 kWh/day to a maximum of 490 kWh/day, with a median charging potential (stationary time) across taxis of 7.7 h/day to 10.6 h/day. The potential for charging from solar PV was 0.38 kWh/m2 to 0.90 kWh/m2. Our simulator and results will allow traffic planners and grid operators to assess and plan for looming electric vehicle roll-outs, and could lead to a new funding model for transport in Africa.
Mother-Child Reminiscing about Emotionally Negative Events and Children’s Long-Term Mental Health
Authors: Koh Jessie Bee Kim , Wang Qi
Published: June 2021

The present study examined the longitudinal relation between mother-child reminiscing of emotionally negative events and children’s mental health. European-American and Chinese-American mothers discussed with their 4.5-year old children an event that was emotionally negative to the child. At age 7, children’s mental health was assessed, including measures for externalizing problems, internalizing problems, negative social self (an Asian-salient dimension of depression), behavioral problems, and socially adaptive behavior. Independent of culture, maternal reference to negative emotional terms was related to fewer externalizing, internalizing, and behavior problems in children, maternal attribution of emotions to children was associated with lower negative social self in children, maternal explanation of children’s emotions was linked to fewer externalizing problems and lower negative social self in children, and maternal reconfirmation of the explanations was related to fewer externalizing and behavioral problems in children. In contrast, maternal attribution of emotions to other people was associated with more externalizing problems and higher negative social self in children of both cultures. Some important cultural differences emerged. Chinese-American mothers’ mention of negative emotional terms was linked to lower negative social self in children, and Chinese-American mothers’ reconfirmation of explanation was related to more socially adaptive behaviors in children. No such relations were found in the European-American sample. The findings underscore the importance of family emotional reminiscing for children’s long-term well-being and the role of culture in shaping the process.
Differences and Similarities between Leaders and Non-Leaders on Psychological Distress, Wellbeing and Challenges at Work
Authors: Wallis Amanda , Robertson Jeremy , Bloore Rebecca , Jose Paul
Published: June 2021

In this paper, we examined differences and similarities in wellbeing outcomes (flourishing and satisfaction with life), psychological distress, work and non-work challenges, and perceptions of organisational support and climate between groups of senior leaders, team leaders, and team members across New Zealand (N = 4,215). Results indicated that non-leaders (team members) reported greater non-work life challenges, lower flourishing and satisfaction with life, greater psychological distress, and more negative perceptions of their organisational support and climate compared to team leaders and senior leaders. Team leaders and senior leaders reported more work-related challenges (work demands and poor peer support) and lower satisfaction with their work life balance. Mediation analysis found that work factors significantly mediated the relationship between leadership status (leader versus non leader) and psychological distress, flourishing and life satisfaction. Findings support the necessity for targeted interventions for different groups within organisational hierarchies. Further, they emphasise the need for proactive and multi-level approaches to building workplace wellbeing to foster wellbeing in all employees regardless of their leadership status. We make recommendations for consulting psychologists to achieve these goals and build psychologically healthy and thriving workplaces.
How Children’s Media and Teachers Communicate Exclusive and Essentialist Views of Science and Scientists
Authors: Wang Michelle Momo , Cardarelli Amanda , Leslie Sarah-Jane , Rhodes Marjorie
Published: June 2021

Language that uses noun labels and generic descriptions to discuss people who do science (e.g., “Let’s be scientists! Scientists discover new things”) signals to children that scientists are a distinctive category. This identity-focused language promotes essentialist beliefs and leads to disengagement from science among young children in experimental contexts. The extent to which these cues shape the development of children’s beliefs and behaviors in daily life, however, depends on (a) the availability of identity-focused language in children’s environments, and (b) the power of these cues to shape beliefs over time, even in the noisier, more variable contexts in which children are exposed to them. Documenting the availability of this language, linguistic coding of children’s media (Study 1) and prekindergarten teachers’ language from one science lesson (Study 2; n = 103; 98 female, 1 male, 4 unknown; 66% White, 8% African American, 6% Asian/Asian American, 3% Mixed/Biracial; 21% of the sample, of any race, identified as Hispanic/Latinx), confirmed that identity-focused language was the most common form of science language in these two contexts. Further, children (Study 3; n = 83; Mage = 4.36 years; 43 female, 40 male; 64% White, 12% Asian/Asian American, 24% Mixed/Biracial; 36% of the sample, of any race, identified as Hispanic/Latinx) who were exposed to lower proportions of identity-focused language from their teachers developed increasingly inclusive science beliefs and greater science engagement over time. These findings suggest that linguistic input is an important mechanism through which exclusive beliefs about science are conveyed to children in daily life.
Situation awareness in remote operators of autonomous vehicles: Developing a taxonomy of situation awareness in video-relays of driving scenes
Authors: Mutzenich Clare , Durant Szonya , Helman Shaun , Dalton Polly
Published: June 2021

Even entirely driverless vehicles will sometimes require remote human intervention. Existing SA frameworks do not acknowledge the significant human factors challenges unique to a driver in charge of a vehicle that they are not physically occupying. Remote operators will have to build up a mental model of the remote environment facilitated by monitor view and video feed. We took a novel approach to 'freeze and probe' techniques to measure SA, employing a qualitative verbal elicitation task to uncover what people ‘see’ in a remote scene when they are not constrained by rigid questioning. Participants (n=10) watched eight videos of driving scenes randomised and counterbalanced across four road types (motorway, rural, residential and A road). Participants recorded spoken descriptions when each video stopped, detailing what was happening (SA Comprehension) and what could happen next (SA Prediction). Participant transcripts provided a rich catalogue of verbal data reflecting clear interactions between different SA levels. This suggests that acquiring SA in remote scenes is a flexible and fluctuating process of combining comprehension and prediction globally rather than serially, in contrast to what has sometimes been implied by previous SA methodologies (Endsley, 2000; Endsley, 2017; Jones & Endsley, 1996). Inductive thematic analysis was used to categorise participants’ responses into a taxonomy aimed at capturing the key elements of people’s reported SA for videos of driving situations. We suggest that existing theories of SA need to be more sensitively applied to remote driving contexts such as remote operators of autonomous vehicles.
Meta-Analysis of the “Ironic” Effects of Intergroup Contact
Authors: Reimer Nils Karl , Sengupta Nikhil Kumar
Published: June 2021

Growing evidence suggests that intergroup contact, psychology’s most-researched paradigm for reducing prejudice, has the ‘ironic’ effect of reducing support for social change in disadvantaged groups. We conducted a preregistered meta-analytic test of this effect across 98 studies with 140 samples of 213,085 disadvantaged-group members. As predicted, intergroup contact was, on average, associated with less perceived injustice (r = -.07), collective action (r = -.06), and support for reparative policies (r = -.07). However, these associations were small, variable, and consistent with alternative explanations. Across outcomes, 25–36% of studies found positive associations with intergroup contact. Moderator analyses explained about a third of the between-sample variance, showing that, at least for perceived injustice, associations with intergroup contact were most consistently negative in studies that measured direct, qualitatively positive contact among adults. We also found evidence for an alternative explanation for the apparent ‘ironic’ effects of intergroup contact as, after controlling for the positive association of negative contact with support for social change, positive contact was no longer associated with any of the outcomes. We close by discussing strengths and limitations of the available evidence and by highlighting open questions about the relationship between intergroup contact and support for social change in disadvantaged groups.
Hello again, ANOVA: rethinking ANOVA in the context of confirmatory data analysis
Authors: Jin Haiyang
Published: June 2021

Analysis of variance (ANOVA) is one of the most popular statistical methods employed in psychological research. Despite its widespread usage, the appropriateness of the ways in which ANOVA is used in practice is not well-discussed. For instance, ANOVAs are frequently used as exploratory data analysis, even in confirmatory studies with explicit research questions and hypotheses. Such misapplication may invalidate some ANOVA conventions, resulting in reduced statistical power of detecting effects of interest, and even threatening the validity of research conclusions. There are many widely-used ANOVA conventions, such as conducting post-hoc and simple effect analysis only when the main effect and interaction are significant, performing more ANOVAs by collapsing or separating one factor depending on the statistical significance of a higher-order interaction, and so on. This paper first evaluates the appropriateness of these conventions, then discusses the potential motivations possibly misunderstood by researchers, and provides practical suggestions. Moreover, this paper proposes to control the Type I error rate with Hypothesis-based Type I Error Rate (HER). Not only does HER consider the number of tests, but it also emphasizes the logical relationships among tests in rejecting the null hypothesis of research interest. Furthermore, this paper uses concreate examples to introduce the simple interaction analysis. For many studies, this technique can employ the most straightforward interaction to test effects of interest. This paper additionally reviews ANOVA limitations and its alternative methods. Pre-registration and open science are recommended to provide clarity for the selection of appropriate ANOVA tests in both confirmatory and exploratory studies.
Implementation of ICT tools to improve the object-oriented distance education in India: A perspective
Authors: Raghava Gudapati Naresh , Kumar Darbha V Ravi
Published: June 2021

India, being a country with a majority youth population, has a good opportunity to strengthen its economy in the next few decades. However, this could only be possible, if the youth population is trained with the required skill-set for the job market with improved opportunities for higher education. Unfortunately, the percentage of higher education enrolment does not possess encouraging numbers due to various social & economic reasons. The ratio in the coming years can be improved by offering the higher education courses in open & distance learning mode (ODL). Recently University Grants Commission (UGC also eased the norms for the higher educational institutes to offer ODL programs. However, the present ODL programs that are being offered were challenged with (i) lack of quality checks (ii) lack of paradigm shift in the course delivery, which is still through correspondence mode (iii) the degrees offered by the distance mode are not on par with regular courses. In this view, it is time to assess the quality of the present ODL programs and the necessary steps have to be initiated to improve the quality of the program. Due to the COVID 19 pandemic condition, major parts of the world dependent on online classes for the delivery of the regular courses, in this view, various tools for delivery and assessment are being widely used/developed. The integration of these tools with the present corresponding courses shall improve the quality of the courses. Herein, we comprehensively present the above-mentioned problems and solutions to improve the quality of ODL courses in India.

Published: June 2021

This research project studies love in Charles Dickens’s Great Expectations through Pip’s ego fluctuations. Freud’s division of the human psyche into the three components of id, ego and superego is applicable to the analysis of the rise and fall of the hero in his quest for Estella’s love. Four main questions have been dealt with: First, what makes up Pip’s id when it comes to love? Second, what are the main components of his superego that stand in the way of his love? Third, does Pip’s ego succeed in striking a balance between his id and superego? In what ways does it fail? And fourth, how does it eventually succeed if ever? The study has managed to answer its key research questions: First, Pip’s id is illustrated in the feelings and actions exerts in order to win Estella’s love. Second, Pip’s superego is mainly made up of the attitudes of characters that stand in his way. Third, Pip’s distress at the attitudes of Estella, Miss Havisham, Biddy and his friends, bring Pip’s ego to its worst situation. Fourth, the quest of Pip’s ego for winning Estella’s heart finally becomes possible mainly thanks to Miss Havisham’s repentance and Estella’s transformation.
The Appropriation of Innocence: from Shelley’s Frankenstein to Ahmed Saadawi’s Frankenstein in Baghdad
Authors: Mahmood Karzan Aziz
Published: June 2021

This paper demonstrates the appropriation of innocence in Shelley’s Frankenstein, Or the Modern Prometheus (1818) and Frankenstein in Baghdad (2013) by Ahmed Saadawi. These novels are selected because the latter appropriates the creator and creature characters and contextualizes them into the American-Iraq 2005 post-war period. In Shelley’s Frankenstein, Victor Frankenstein, scientifically, gives life to a dead body amalgamated from other body parts, which start murdering and revenging upon his creator. Whereas, in Saadawi’s twenty-first century Frankenstein, a person who is formed from others’ dead bodies by merely a junk dealer, starts murdering and revenging upon other people. On the one hand, Frankenstein, a science student, sought to answer the question of human revival theoretically and practically. Therefore, after he resurrects the dead, it becomes monstrous due to its negligence and physical hideousness by its creator. On the other hand, the Iraqi Frankenstein’s creator, Hadi, celebrates collecting old materials in a non-scientific manner, including humans’ dead body parts, in order to give value to them by offering them worthy of proper burials. The resurrected creatures transform into more powerful beings than their creators as reactions against isolation and injustice. For that, both Frankenstein and Hadi lose control over their creations, who instigate new life cycles. Hence, the ethical responsibility of invention underlies the concept of innocence which this paper intends to analyze vis-à-vis the creators and their creations.
Lexical Asymmetry as a Translation Problem Arising in the Holy Quran
Authors: Al-Tamari Emad Ahmed , Eddin Eyhab Abdulrazak Bader
Published: June 2021

Coupled with copious evidence and cogent illustrations, this article charts an important development in the field of translating the Holy Quran. It breaks new ground in a new type of problems inherent in the translation of the Quran. It is designed to catch translators’ alert senses to look beyond the traditional approach to translation, i.e. looking for the superficial equivalent. It critically discusses the long-standing proclivity for the deeply-held belief in the existence of absolute synonyms in the Quran. Although the examples given are not very exhaustive due to space constraints, the author’s unbridled reason pushes him to how far semantic propinquity exists in the Quran, developing a plethora of new checklists which will definitely act as a springboard to lay groundwork to any translator. The paper draws a conclusion that the seemingly verb and noun synonyms in the Quran are not so, resulting in a lexical asymmetry in translation. This paper zooms in on a new type of sense relationships, which involve a pair of words with similar meaning, but are made up of the same root morphologically. The paper takes three very popular and mesmerizing translations of the Quran as a point of reference. This paper shatters the fervent belief that one word can be a full equivalent to seemingly synonymous words in the Quran. This is a strong call on translators to start looking at new issues in the translation of the Quran from different standpoints, an arresting fact we need to grasp.
Trade Policy and the Marshall–Lerner Condition: Application of the Tobit Model
Authors: Masuda Kazuto
Published: June 2021

This paper establishes the micro-foundation for the income-price approach to export and import functions from the firm’s profit maximization problem. Following Boyd et al. (2000), we derive the Marshall–Lerner condition mathematically and analyze the effects of home and foreign trade policies, such as the minimum access and quantitative trade restriction, on the Marshall–Lerner condition. In conclusion, such trade policies make the condition theoretically difficult to hold since the marginal effects of the Tobit estimates under deterministic trade policies are always lower than the ordinary least squares (OLS) estimates under no trade policies in absolute values.
Translation and the Individual Talent: Ambiguity in the Qurʾanic Text and the Role of the Translator
Authors: Qassas Raed A.
Published: June 2021

This article examines the impact of traditional Tafsīr, the exegesis of the Qur’an, on the translation of the Qurʾanic text into English. Caught between the authority of tradition and the sensitivity of translating a sacred text, many translators refrain from practicing interpretation as an integral part of the translation process, whereas others defiantly dismiss the authority of tradition en masse. The significance of the study lies in undermining over-reliance on explanatory texts yields semantically dogmatic interpretations recurrently manifest in the various English renditions of the Qurʾan. The article questions what is called the etic translation that involves translation from the perspective of one who remains an outsider and does not participate in the interpretation. The finding of the study lead to the conclusion that many translations of the Qurʾan disregard possible interpretations because of rehashing interpretations handed down from traditional exegeses. The article also argues that translators have an active, interpretative role in the translation of the Qurʾan. Compatibility with tradition does not mean being constricted exclusively by Tafsīr. Tradition is a frame of reference, a point of departure for new horizons of interpretation where interpretation is viewed as an augmentation to tradition, not sedition.
Embodied Oppression and Psychological Trauma: The Subjugation of O-lan’s in Pearl Buck’s Novel the Good Earth
Authors: Hussein Hanan Abbas
Published: June 2021

The present paper is qualitative; it illustrates the sense of oppression, negligence, and marginalization; Chinese women suffer from in their society. There, women are bound to doing housework and rearing children; they are a mere tool to meet their husbands’ pleasures and find concubines when needed. Accordingly, the study examines the sources , and types of psychological trauma experienced by the character O-lan, and later by the oppressors, her husband and his new wife, Wang Lung , in Buck’s novel The Good Earth. To meet the objective of the study, Robinson, Smith, & Segal’s (2020) types of trauma will be adopted in the analysis. Such a study help know more about the traditions and values of Chinese society, the role of women there. It further reflects the negative societal consequence s of abusing and humiliating women, and the curse men will gain due to their unjust treatment of their wives. The psychological trauma of O-lan is highly indicated by her husband’s speech and behavior. He constantly belittles her role a wife, neglecting her emotions. She keeps her agony and depression till she collapsed.

Pokhara is one of the rapidly growing cities of Nepal. It is the second-largest metropolitan city after Kathmandu. Because of the renowned temples, monasteries, lakes, adventure sports, and being close to the well-known Annapurna Range, it is considered as the tourism capital of Nepal. Millions of tourist visit this naturally gifted city every year contributing to considerable economic development. This economic prospect has attracted thousands of migrants every year leading to 67% growth in population in the last decade. The rapid population growth and urbanization without long-term planning and firm regulation have severely affected the development of sustainable infrastructure, preservation of the public space and natural resources. This has further impacted the tourism, economy, health and wellbeing, environment, and social aspect of the city. This article aims to generate strategies for retaining and improving the natural beauty of the city (focusing on the Phewa Lake area) by enhancing the economy and environment, rejuvenating social and cultural values, elevating the health and wellbeing of the people, and strengthening and promoting sustainable development. In this article, literature reviews, interviews, and field surveys were undertaken and four major improvements/developments are recommended for the beautification of Pokhara City. The recommendations are: preservation and development of open space into self-sustaining cohesive community parks, citizen-centred urban development, improvement of current transport infrastructure, and conservation of natural resources such as water, vegetation, and landscape.

Authors: Joshi Ishwar , Adhikari Surya Prasad
Published: June 2021

In this study, biodiesel from the stem of Pinus roxburghii was prepared by steam distillation process. Consequently, the physical and thermal properties of pine biodiesel (P100), and 20 % pine-biodiesel and 80 % diesel (P20) were tested on American Society for Testing and Materials (ASTM) standards. The test results confirmed that the thermophysical properties of pine biodiesel and its blend were suitable for the fuel in diesel engine without any modification in the test engine. Eventually, the engine performance and combustion parameters were evaluated for pine-biodiesel blend for 5 % biodiesel and 95 % diesel (P5), 10 % biodiesel and 90 % diesel (P10), 15 % biodiesel and 85 % diesel (P15) and P20, and compared with diesel on Kirloskar Single Cylinder Compression Ignition Engine for a compression ratio of 15:1. In the midst of those in different blends evaluated, P15 showed the better brake specific fuel consumption (BSFC) i.e 18.75 % lower than diesel fuel particularly up to 50 % of the engine load. However, at higher load, decrease rate in BSFC of P15 fuel is lower than engine load up to 50 %. Similarly, brake thermal efficiency (BTE) of P15 increases to 13.5% mainly on 50 % loading condition of the engine. At above, increment rate of BTE of pine oil biodiesel compared to diesel decreases. The brake power (BP) and brake mean effective pressure (BMEP) of P15 also found nearer to diesel. However, the BP of P15 found higher compared to diesel in all loading conditions. Thus, from the experimental investigations, P15 blend of pine oil biodiesel was found to be amenable for its use in compression ignition (CI) engine without any modification, as the BTE and SFC were found to better and, BP, indicated power (IP) and BMEP were also found nearer to diesel fuel.

Indoor Snow Park adalah wahana rekreasi bertema salju di Pekanbaru, selain berfungsi sebagai rekreasi bangunan juga dapat berfungsi sebagai sarana olahraga es. Pekanbaru di pilih sebagai lokasi desain karena kurangnya sarana rekreasi dan sebagai bentuk mensimulasi alam musim dingin di kota yang beriklim tropis. Indoor Snow Park menerapkan prinsip desain Jean Nouvel karena prinsip desain Jean Nouvel selaras dengan fungsi bangunan dimana pada setiap bangunan yang ia rancang Jean selalu memberikan suasana yang kontras pada bangunanya, sama halnya dengan rekreasi salju di tengah iklim tropis. Konsep yang diterapkan pada Indoor Snow Park ini adalah Snowflakes. Konsep ini terinspirasi dari fenomena turunnya salju di negara subtropis, yang sejalan dengan fungsi rancangan yaitu wadah rekreasi musim dingin. Analogi dari Kristal es ini lah yang kemudian diterapkan pada bentuk, fasad, interior dan lansekap Indoor Snow Park.
