PMID: 39145232 DOI: 10.7717/peerj-cs.2203

In recent years, e-commerce platforms have become popular and transformed the way people buy and sell goods. People are rapidly adopting Internet shopping due to the convenience of purchasing from the comfort of their homes. Online review sites allow customers to share their thoughts on products and services. Customers and businesses increasingly rely on online reviews to assess and improve the quality of products. Existing literature uses natural language processing (NLP) to analyze customer reviews for different applications. Due to the growing importance of NLP for online customer reviews, this study attempts to provide a taxonomy of NLP applications based on existing literature. This study also examined emerging methods, data sources, and research challenges by reviewing 154 publications from 2013 to 2023 that explore state-of-the-art approaches for diverse applications. Based on existing research, the taxonomy of applications divides literature into five categories: sentiment analysis and opinion mining, review analysis and management, customer experience and satisfaction, user profiling, and marketing and reputation management. It is interesting to note that the majority of existing research relies on Amazon user reviews. Additionally, recent research has encouraged the use of advanced techniques like bidirectional encoder representations from transformers (BERT), long short-term memory (LSTM), and ensemble classifiers. The rising number of articles published each year indicates increasing interest of researchers and continued growth. This survey also addresses open issues, providing future directions in analyzing online customer reviews.
Fulltext A Systematic review of sexual and reproductive health needs, experiences, access to services, and interventions among the rohingya and the afghan refugee women of reproductive age in Asia

PMID: 36308272 DOI: 10.4103/WHO-SEAJPH.WHO-SEAJPH_144_21

INTRODUCTION: Approximately 9.2 million refugees live in Asia, with most originating from Afghanistan and Myanmar, and half of them are women, girls, and children. Humanitarian crises disrupt the existing health-care system, limiting access to sexual and reproductive health (SRH) services. This review explores the SRH status of Afghan and Rohingya refugee women of reproductive age in Asia and their needs and experiences in accessing these services and commodities.
MATERIALS AND METHODS: We used the PRISMA checklist and searched for qualitative and quantitative peer-reviewed studies from five online bibliographic databases, SCOPUS, EMBASE (Ovid), MEDLINE (Ovid), CINAHL, and PROQUEST, from January 2000 to April 2021. Content analysis was undertaken following the minimum initial service package objectives.
RESULTS: Fifteen studies were included in this review from four countries: Bangladesh (5), Pakistan (5), Iran (4), and Malaysia (1). Approximately 50.91% of Rohingya and 54% of Afghan refugee women used contraceptives. About 56.6% of Afghan refugee mothers experienced pregnancy-related complications, one-third received antenatal care, and low birth weight was 2.6 times higher among infants born to Afghan refugee mothers than to Pakistani-born mothers. One out of five Rohingya women received delivery-related care. Approximately 72% of Rohingya and 79.8% of Afghan refugee women had experienced gender-based violence, and 56.5% of Rohingya women engaged in unwanted sexual intercourse with their husbands.
CONCLUSION: Social norms, stigma, cultural values, distrust of providers, inadequate staff, and prohibition by family members limit their access to SRH services and influence their needs, knowledge, and perceptions regarding SRH.

BackgroundGreen agile leadership (GAL) combines adaptability and environmental commitment to address sustainability challenges. In China resource-intensive healthcare sector, sustainable practices are vital to achieving Sustainable Development Goals (SDGs).ObjectiveThis study investigates the influence of GAL on pro-environmental behavior (PEB), focusing on the mediating role of environmental passion (EP) and the moderating effect of face consciousness (FC).MethodsA quantitative research design was employed, utilizing survey data collected from a sample of employees in hospitals. Structural equation modeling (SEM) was used to analyze the data and test the proposed relationships via MPLUS.ResultsThe study findings indicate that GAL has a significant positive impact on PEB. Additionally, EP was identified as a partial mediator in the relationship between GAL and PEB. The moderating effect of FC indicated that employees with higher levels of EP and greater FC in their work environment exhibit enhanced PEB within their organization.ConclusionsThe originality and value of this research lie in its comprehensive examination of the underlying mechanisms via mediating and moderating factors in the relationship between GAL and PEB. Specifically, this research contributes to the growing body of literature on GAL and PEB by shedding light on the mediating role of EP and the moderating role of FC. This study offers theoretical insights and practical recommendations for health industry to effectively manage PEB through GAL and the cultivation of EP and FC among employees.

Misconceptions about neuroscience among teachers and their application to education may lead to ineffective teaching strategies and waste valuable resources. The main objective of this paper is to study neuroscience knowledge, beliefs in neuromyths and their application in Malaysian classrooms. An online survey was conducted among (n = 501) school teachers, covering 14 neurofacts, four neuromyth, and their application in education. Results show more than 75 % of teachers of all levels of experience endorsed the unfounded idea that 'Individuals learn better when they receive information in their preferred learning style and 80 % of these teachers endorsed applying the VAK idea in their teaching practice. The findings also show that neuromyth agreement was positively correlated with practice agreement (r = 0.181, p < 0.001). Interestingly, numerous studies from various countries have highlighted the prevalence of neuromyths, and Malaysia is no exception and consistent across countries, particularly regarding beliefs about learning styles. With the growing popularity of pseudoscientific practice among school teachers worldwide, many educators who are enthusiastic about possible applications of neuroscience findings in the classroom find it difficult to distinguish pseudoscience from scientific facts.

Language classrooms are embedded with a wide range of emotions. Emotions play a significant role in affecting learners' language learning and academic performance. Yet, while the role of emotions in L2 classrooms has been recognized, very scant studies have investigated the underlying theoretical frameworks in great depth with regard to the conceptualization and causation of emotions. Moreover, very few review studies have paid sufficient attention to the antecedents or causes of emotions underpinned by certain theories in the field of SLA. Therefore, to offer a complementary review of emotion-related theories and provide fresh insights into the emotional research in SLA, the present study first explains the theoretical approaches of the conceptualization and causation of emotions, elucidates how these theories are applied into the emotional research in language learning, and identifies the effect of the interplay between cognitive, psychological, social, and contextual factors on the emotional development in the language learning. Finally, practical implications, like emotional regulation strategies for both language teachers and learners and future directions, like the integration with AI tools for L2 researchers, language teachers, and teacher educators who are interested in emotional research are also discussed.

Role of the government towards stock markets and carbon emissions: evidence from wavelet approach

Waris M, Din BH

Environ Sci Pollut Res Int, 2024 Feb;31(7):11285-11306.

The government of any country can play a great role in promoting economic and environmental policy reforms in both normal and crisis periods, but during the crisis period, the role of the government should take the economy into a recovery position. The stock market is the backbone of the financial system that needs the government's attention, especially in the period of financial stress and environmental protection is the responsibility of every economy to live in a healthy environment. Combining this motive, this study analyzed the role of the government towards the stock market and carbon emission by using different approaches, including the wavelet approach, OLS regression, and the Granger causality test. The wavelet approach is useful for analyzing the role of the government at different time intervals by using the time horizon from 1993 to 2021. World governance's six indicators in terms of voice and accountability, control of corruption, rules of law, regulatory quality, political stability, and government effectiveness are used as the proxy for the role of the government. Our findings show that all WGI indicators have a positive relationship with the stock market of Malaysia except voice and accountability while concerning voice and accountability, the role of the government of Malaysia is negative on the stock market. Similarly, our findings also show that the effective government governance mechanism through WGI indicators has a significant positive impact on CO2 emission due to industrialization. Furthermore, findings of the Granger causality test reveal that all the WGI indicators cause to stock market of Malaysia, and political stability has bi-directional causality indicating stock market index is also a factor that caused the political stability within Malaysia. In the Granger causality results of the CO2 and WGI indicators, there is unidirectional causality found between rules of law and regulatory quality with CO2 emission. This study advocated strong implementations for the investors for investment decisions in effective governance countries and implications for the government to remove their weakness by making effective governance related to the economy and as well as the environments within the country.
Nexus of the CSR disclosures and corporate financial performance: evidence from Asian countries climate policy uncertainty

Waris M, Din BH

Environ Sci Pollut Res Int, 2024 Jan;31(2):1995-2008.
PMID: 38049691 DOI: 10.1007/s11356-023-31307-9

Financial performance is a critical aspect of a company's overall health and sustainability. It directly influences investor decisions, stock market performance, credit ratings, and the company's ability to access capital. Corporate financial performance is influenced by multitude of facts, both internal and external such as disclosure of the information, and social and environmental factors. On the ground of the facts, we aimed to investigate non-financial firms that belong to Asian economies affected by climate policy uncertainty and corporate social responsibility disclosures in terms of their financial performance. To conduct quantitative study analysis, we used the two effective statistical tools such as two-stage regression method and generalized method of movement (GMM). Our results show that corporate high value of social responsibility disclosure and climate policy uncertainty has significant negative impact on return on asset (ROA) of the listed organizations of China, Pakistan, and India. Moreover, CSR disclosure attributes higher values such as social (SC) and governance score (GOV), and climate policy uncertainty (CPU) has significant negative relationship with return on equity (ROE) and earning per share (EPS) respectively, while a higher value of ESG total score and the environmental (ENV) score has a significant positive impact on ROE and EPS. Additionally, the research concludes that climate policy uncertainty is a key factor that motivates CSR disclosure practices, which ultimately improves corporate financial performance. Moreover, we concluded from our finding that the climate policy uncertainty creates ambiguity surrounding government regulations, international agreements, or market mechanisms that affect financial performance. Moreover, environmental disclosure information that has the large part in total ESG scores attract the investors around the globe which leads to rise in the financial performance, while the other attributes of the CSR disclosure decrease performance. This study advocated the great implications for researchers, investors, the government, and regulatory authorities. Policy makers can make the policy about the CSR disclosure for creating the good image of the organization to attract investors around the globe.

Zhao W, Irfan M

Environ Sci Pollut Res Int, 2023 Oct;30(46):102772-102789.
PMID: 37672158 DOI: 10.1007/s11356-023-29554-x

In the face of the challenge of balancing urban economic development and environmental protection, the concept of a healthy city has emerged as a promising model for sustainable urban development. This study empirically investigates the impact of healthy city construction on green growth by utilizing a difference-in-difference model estimation on a panel dataset of 279 Chinese prefecture-level cities from 2007 to 2019. The findings reveal that healthy city construction significantly contributes to green growth, particularly in pilot cities, and this effect is observed across cities of different sizes and economic bases. Additionally, we identify two channels through which healthy city construction promotes green growth: enhancing innovation capacity and enriching human resources. These findings have implications not only for Chinese cities navigating the path towards green growth but also for other developing nations striving for economic transformation and environmentally sustainable development.

PMID: 29084700

The absence of chromophore and/or conjugated system, prerequisite for UV and florescent light detection, or absorbance at very low wavelength necessitates the development of simple and reliable methods for the determination of amikacin sulphate. Therefore, the present study describes for the first time dynamics of the drug derivatization using ninhydrin reagent and development and validation of a simple RP-HPLC method, using diode array detector (DAD). The variables such as heating time, heating type, drug-reagent ratio, reagent composition and storage temperature of the derivative were optimized. The analyte and aqueous ninhydrin solution upon heating for 2.00-5.00 min produced the colored drug-derivative which was stable for one month at refrigeration. The derivatized drug (20.00μL) was eluted through a column - Eclipse DB-C18 (5.00 µm, 4.60×150.00 mm), maintained at 25°C- using isocratic mobile phase comprising water and acetonitrile (70:30, v/v) at a flow rate of 1.00 mL/min, and detected at 400 nm. The method was found to be reliable (98.08-100.72% recovery), repeatable (98.02-100.72% intraday accuracy) and reproducible (98.47-101.27% inter day accuracy) with relative standard deviation less than 5%. The results of the present study indicate that the method is easy to perform, specific and sensitive, and suitable to be used for the determination of amikacin sulphate in bulk and pharmaceutical preparations using less expensive/laborious derivatization.

Muhammad SA, Nordin N, Mehat MZ, Fakurazi S

Cell Tissue Res, 2019 Feb;375(2):329-344.
PMID: 30084022 DOI: 10.1007/s00441-018-2884-0

Articular cartilage defect remains the most challenging joint disease due to limited intrinsic healing capacity of the cartilage that most often progresses to osteoarthritis. In recent years, stem cell therapy has evolved as therapeutic strategies for articular cartilage regeneration. However, a number of studies have shown that therapeutic efficacy of stem cell transplantation is attributed to multiple secreted factors that modulate the surrounding milieu to evoke reparative processes. This systematic review and meta-analysis aim to evaluate and compare the therapeutic efficacy of stem cell and secretome in articular cartilage regeneration in animal models. We systematically searched the PubMed, CINAHL, Cochrane Library, Ovid Medline and Scopus databases until August 2017 using search terms related to stem cells, cartilage regeneration and animals. A random effect meta-analysis of the included studies was performed to assess the treatment effects on new cartilage formation on an absolute score of 0-100% scale. Subgroup analyses were also performed by sorting studies independently based on similar characteristics. The pooled analysis of 59 studies that utilized stem cells significantly improved new cartilage formation by 25.99% as compared with control. Similarly, the secretome also significantly increased cartilage regeneration by 26.08% in comparison to the control. Subgroup analyses revealed no significant difference in the effect of stem cells in new cartilage formation. However, there was a significant decline in the effect of stem cells in articular cartilage regeneration during long-term follow-up, suggesting that the duration of follow-up is a predictor of new cartilage formation. Secretome has shown a similar effect to stem cells in new cartilage formation. The risk of bias assessment showed poor reporting for most studies thereby limiting the actual risk of bias assessment. The present study suggests that both stem cells and secretome interventions improve cartilage regeneration in animal trials. Graphical abstract ᅟ.
Irreducible Dorsal Distal Interphalangeal Joint Dislocation of Finger: A Case Report and Perspectives on Management

Sem SH, Omar MF, Muhammad Nawawi RF

Cureus, 2019 May 02;11(5):e4588.
PMID: 31309013 DOI: 10.7759/cureus.4588

Irreducible closed dorsal dislocation of distal interphalangeal (DIP) joint of the finger is a rare injury. The causes of irreducibility of the DIP joint are volar plate interposition, entrapment of flexor digitorum profundus tendon behind the head of middle phalanx, and buttonholing of the middle phalanx head through the volar plate or flexor tendon. Open reduction with a volar approach is recommended with the advantages of better wound healing, ease of releasing entrapped structures, and possibilities of a volar plate, collateral ligaments, and/or flexor tendon repair. We report a case of irreducible dorsal dislocation of left ring finger DIP joint secondary to volar plate interposition treated successfully with open reduction.

Population density, growth, survival, water quality and larval stage index of purple mud crab, Scylla tranquebarica at different feeding regimes and the data on ingestion rate of chosen microalgae, survival and larval development of blue swimming crab, Portunus pelagicus are presented. A twenty days of S. tranquebarica larval culture from zoeal 1 until megalopa stage under two different feeding regimes of A) Rotifer, Artemia nauplii and shrimp meat and B) Rotifer, Artemia nauplii and artificial feed is shared. A method on investigation of individual larvae of P. pelagicus capability to catch four different types of microalgae within 24 h is also shared. Direct eye observation, data collected through the larval rearing culture of S. tranquebarica and further statistical analysis were done daily until the crabs reached the megalopa stage. The result obtained from the optimum density of selected microalgae fed by individual larvae of P. pelagicus will be combined with the highest survival rate and larval stage index to develop feeding schedule for crab larvae P. pelagicus. This dataset has not previously been published and is of great potential for further comparison with other - and future investigation of various feeding regimes affected the crab culture. The collected information could be used as a standard feeding regime for nursery and hatchery seed production of others portunids crabs. The data described in this article are available as a supplementary file to this article.

PMID: 33371596 DOI: 10.1111/1541-4337.12184

Mimosa pudica Linn. (Family: Mimosaceae) is used as an ornamental plant due to its thigmonastic and nyctinastic movements. M. pudica is also used to avoid or cure several disorders like cancer, diabetes, hepatitis, obesity, and urinary infections. M. pudica is famous for its anticancer alkaloid, mimosine, along with several valuable secondary metabolites like tannins, steroids, flavonoids, triterpenes, and glycosylflavones. A wide array of pharmacological properties like antioxidant, antibacterial, antifungal, anti-inflammatory, hepatoprotective, antinociceptive, anticonvulsant, antidepressant, antidiarrheal, hypolipidemic activities, diuretic, antiparasitic, antimalarial, and hypoglycemic have been attributed to different parts of M. pudica. Glucuronoxylan polysaccharide extruded from seeds of M. pudica is used for drug release formulations due to its high swelling index. This review covers a thorough examination of functional bioactives as well as pharmacological and phytomedicinal attributes of the plant with the purpose of exploring its pharmaceutical and nutraceutical potentials.
Congenital pseudoarthrosis of the tibia: healing by lengthening over a rod without compression of the nonunion. A preliminary report

Muhammad Abdul Jamil MK, Abdul Rashid AH, Ibrahim S

J Pediatr Orthop B, 2013 May;22(3):207-12.
PMID: 22182834 DOI: 10.1097/BPB.0b013e32834ecc01

This preliminary report is on two patients with congenital pseudoarthrosis of the tibia who had a persistent nonunion following intramedullary rodding and bone grafting. We do not advocate repeated surgery to achieve union. When limb length discrepancy becomes greater than 5 cm, we proceeded with an Ilizarov procedure with the primary aim of equalizing limb length rather than achieving union. Healing of the pseudoarthrosis occurred in both patients after lengthening over the intramedullary rod without compression of the nonunion site. We believe that union occurs because of hyperaemia during the lengthening. This approach minimizes the repeated surgeries that are usually needed and thus ensures a more normal childhood without frequent hospitalizations.

Bone is a specialized connective tissue that functions as the load-bearing structure of the body. Free radicals may affect bone remodeling by regulating osteoclast activity in either the physiological or pathological condition. Vitamin E, a lipid-soluble antioxidant, has been demonstrated to offer protection against osteoporosis and to improve the bone material and structure of animal models. The aim of this study was to observe and compare the effects of alpha-tocopherol (alpha-tocopherol), delta-tocotrienol (delta-tocotrienol), and gamma-tocotrienol (gamma-tocotrienol) on the static and dynamic bone histomorphometric parameters in normal male rats. Thirty-two normal Sprague-Dawley male rats aged 3 months and weighing 200-250 g were randomly divided into four groups. The control group was supplemented with oral gavages of olive oil (vehicle), whereas the alpha-tocopherol, delta-tocotrienol, and gamma-tocotrienol groups were given oral gavages of 60 mg/kg alpha-tocopherol, delta-tocotrienol, and gamma-tocotrienol, respectively. The rats were injected twice with calcein to fluorochrome-label the bones. After 4 months of treatment, the rats were killed, and the left femurs were dissected out and prepared for bone histomorphometry. Both the static and dynamic parameters of the vitamin E-treated groups were better than those of the normal control group. Among the vitamin E-treated groups, the tocotrienol groups showed better histomorphometry results compared to the α-tocopherol group, with the γ-tocotrienol group demonstrating the best effects on both sets of parameters. We concluded that vitamin E can promote bone formation in normal rats, with gamma-tocotrienol being the most potent form of vitamin E.
Financial regulations and sustainability: The role of energy price and climate policy uncertainty

Russia ranks among the top five countries worldwide in terms of carbon emissions, with the energy, transportation, and manufacturing sectors as the major contributors. This poses a significant threat to both current and future generations. Russia faces challenges in achieving Sustainable Development Goal 13, necessitating the implementation of more innovative policies to promote environmental sustainability. Considering this alarming situation, this study investigates the role of financial regulations, energy price uncertainty, and climate policy uncertainty in reshaping sectoral CO2 emissions in Russia. This study utilizes a time-varying bootstrap rolling-window causality (BRW) approach using quarterly data from 1990 to 2021. The stability test for parameters indicates instability, suggesting that the full sample causality test may yield incorrect inferences. Thus, the BRW approach is employed for valid inferences. Our findings confirm the time-varying negative impact of financial regulations on CO2 emissions from energy, manufacturing, and transportation sectors. Additionally, findings confirm time-varying positive impact of energy prices and climate policy uncertainty on CO2 emissions from the energy, manufacturing, and transportation sectors. Strong financial regulations and stable energy and climate policies are crucial for achieving sustainability, highlighting significant policy implications for policymakers and stakeholders.
Performance of T2-based PCA mix control chart with KDE control limit for monitoring variable and attribute characteristics

Ahsan M, Mashuri M, Prastyo DD, Lee MH

Sci Rep, 2024 Mar 28;14(1):7372.
PMID: 38548881 DOI: 10.1038/s41598-024-58052-4

In this work, the mixed multivariate T2 control chart's detailed performance evaluation based on PCA mix is explored. The control limit of the proposed control chart is calculated using the kernel density approach. Through simulation studies, the proposed chart's performance is assessed in terms of its capacity to identify outliers and process shifts. When 30% more outliers are included in the data, the proposed chart provides a consistent accuracy rate for identifying mixed outliers. For the balanced percentage of attribute qualities, misdetection happens because of the high false alarm rate. For unbalanced attribute qualities and excessive proportions, the masking effect is the key issue. The proposed chart shows the improved performance for the shift in identifying the shift in the process.
A study of novel linear Diophantine fuzzy topological numbers and their application to communicable diseases

Zamri SNA, Azeem M, Imran M, Jamil MK, Almohsen B

Eur Phys J E Soft Matter, 2024 Dec 01;47(11):67.
PMID: 39617793 DOI: 10.1140/epje/s10189-024-00460-5

The idea of linear Diophantine fuzzy sets (LDFs) is a novel tool for analysis, soft computing, and optimization. Recently, the concept of a linear Diophantine fuzzy graph has been proposed in 2022. The aim of this research is to extend topological numbers to LDFSs. A real value assigned to a particular graph is known as a topological graph theoretic parameter. We extend the bound of the crisp graph toward the linear Diophantine fuzzy graph (LDFG), including the edge and vertex deletion operations via LDFG theoretic parameters. We also investigate the interesting bound of the LDFGs via LDFG theoretic parameters. Finally, for decision-making problems, we developed an algorithm by exploiting the relationship between LDFG theoretic parameters and LDFSs. Based on the established approach, we discussed a numerical example of an application of a medical diagnosis using the linear Diophantine fuzzy Sombor graph parameter and the first, fifth, and sixth versions of the linear Diophantine fuzzy Sombor graph parameters.
