Abstract

Purpose

Mouth segmentation is one of the challenging tasks of development in lip reading applications due to illumination, low chromatic contrast and complex mouth appearance. Recently, deep learning methods effectively solved mouth segmentation problems with state-of-the-art performances. This study presents a modified Mobile DeepLabV3 based technique with a comprehensive evaluation based on mouth datasets.

Design/methodology/approach

This paper presents a novel approach to mouth segmentation by Mobile DeepLabV3 technique with integrating decode and auxiliary heads. Extensive data augmentation, online hard example mining (OHEM) and transfer learning have been applied. CelebAMask-HQ and the mouth dataset from 15 healthy subjects in the department of rehabilitation medicine, Ramathibodi hospital, are used in validation for mouth segmentation performance.

Findings

Extensive data augmentation, OHEM and transfer learning had been performed in this study. This technique achieved better performance on CelebAMask-HQ than existing segmentation techniques with a mean Jaccard similarity coefficient (JSC), mean classification accuracy and mean Dice similarity coefficient (DSC) of 0.8640, 93.34% and 0.9267, respectively. This technique also achieved better performance on the mouth dataset with a mean JSC, mean classification accuracy and mean DSC of 0.8834, 94.87% and 0.9367, respectively. The proposed technique achieved inference time usage per image of 48.12 ms.

Originality/value

The modified Mobile DeepLabV3 technique was developed with extensive data augmentation, OHEM and transfer learning. This technique gained better mouth segmentation performance than existing techniques. This makes it suitable for implementation in further lip-reading applications.

Abstract

Purpose

This scientific article aims to evaluate the efficacy of the drug Doxorubicin for treating hepatocellular carcinoma (HCC) in Egypt. The study analyzes data from patients referred to a multi-disciplinary consultation at the National Cancer Institute, Cairo University. The study includes 40 intermediate-stage HCC patients who underwent treatment with either Doxorubicin-Lipiodol or Doxorubicin-loaded drug-eluting beads-trans-arterial chemoembolization (DEB-TACE).

Design/methodology/approach

Patients referred to a multi-disciplinary consultation at the National Cancer Institute, Cairo University with a possible diagnosis of HCC in the intermediate stage were eligible for the study.

Findings

The study finds that the plasma peak concentration of Doxorubicin is significantly higher in patients treated with Lipiodol compared to those treated with DEB-TACE. The median plasma peak concentration of patients treated with Lipiodol was significantly higher 424 (202.5–731) than the peak level of patients treated with beads 84.95 (26.6–156.5) with p-value = 0.036. However, there is no significant difference in other pharmacokinetic parameters between the two treatment groups. The research article also investigates the genetic polymorphisms in HCC patients treated with Doxorubicin-Lipiodol and Doxorubicin-loaded DEB-TACE. It identifies a significant association between the ABCB1 gene (C3435T) and the concentration of Doxorubicin in plasma. Patients with the CCand computed tomography (CT) genotypes of ABCB1 have higher concentrations of Doxorubicin compared to those with the TT genotype. Furthermore, the study examines the progression-free survival rates and tumour response in the two treatment groups. It demonstrates that DEB-TACE patients have a higher progression-free survival rate compared to cTACE patients. DEB-TACE also leads to better tumour regression.

Originality/value

The current study helps to increase the understanding of the genetic factors that may contribute to HCC susceptibility in the Egyptian population. However, it is essential to consider that genetic polymorphism is just one aspect of HCC risk, and other factors such as environment, lifestyle and viral infections also play crucial roles. Further research is needed to elucidate the complex interactions between genetic and environmental factors in HCC development among Egyptians.

Abstract

Purpose

Policy for women's entrepreneurship is designed to promote economic growth, not least in depleted rural areas, but very little is known about the contributions of rural women entrepreneurs, their needs or how the existing policy is received by them. Using a theoretical framework developed by Korsgaard et al. (2015), the authors analyse how rural women entrepreneurs contribute to rural development and discuss the implications for entrepreneurship policy. This paper aims to focus on the aforementioned objectives.

Design/methodology/approach

The authors interviewed 32 women entrepreneurs in rural Sweden representing the variety of businesses in which rural Swedish women are engaged. The authors analysed their contributions to rural development by analysing their motives, strategies and outcomes using Korsgaard et al.’s framework of “entrepreneurship in the rural” and “rural entrepreneurship” as a heuristic, interpretative device.

Findings

Irrespective of industry, the respondents were deeply embedded in family and local social structures. Their contributions were substantial, multidimensional and indispensable for rural viability, but the policy tended to bypass most women-owned businesses. Support in terms of business training, counselling and financing are important, but programmes especially for women tend to miss the mark, and so does rural development policy. More important for rural women entrepreneurs in Sweden is the provision of good public services, including for example, schools and social care, that make rural life possible.

Research limitations/implications

Theoretically, the findings question the individualist and a-contextual focus of much entrepreneurship research, as well as the taken-for-granted work–family divide. How gender and how the public and the private are configured varies greatly between contexts and needs contextual assessment. Moreover, the results call for theorising place as an entrepreneurial actor.

Practical implications

Based on the findings, the authors advise future policymakers to gender mainstream entrepreneurship policy and to integrate entrepreneurship and rural development policy with family and welfare state policy.

Originality/value

The paper highlights how rural women respond to policy, and the results are contextualised, making it possible to compare them to other contexts. The authors widen the discussion on contributions beyond economic growth, and the authors show that policy for public and commercial services and infrastructure is indeed also policy for entrepreneurship.

Abstract

Purpose

The purpose of the study is to evaluate the compliance of environmental risk management systems implemented by Moroccan banks with ISO 14001 certification or environmental charters.

Design/methodology/approach

Data were collected through the distribution of an environmental risk management questionnaire to all Moroccan banks’ branches, business centers and various central entities. The study uses regression analysis to model the relationship between environmental management system (EMS) compliance and environmental management explanatory variables to identify the most relevant indicators that can explain the effectiveness and reliability of an EMS.

Findings

Empirical evidence reveals that the evaluation of EMS compliance in Moroccan banks should consider two categories of variables: the first category is related to the culture of environmental risk management, and the second one is related to environmental management practices.

Originality/value

The results show that the “information” variables play a key role in the overall design of an EMS and represent essential variables in the general definition of the environmental policy and in raising awareness and providing information on the bank’s commitment to a pro-environmental approach. The “application” variables confirm that environmental management practices need to be put in place to manage the different environmental risks. The study raises some managerial implications and further research directions.

Abstract

Purpose

Sexual harassment is a pervasive and damaging issue that affects the physical and mental health and well-being of employees in the workplace. It is a serious public health concern that requires urgent attention and action and very dangerous problem in management. Our studies have shown that women are more likely to be the victims of sexual harassment and are more dissatisfied with the situation, organizations have a moral and legal obligation to take proactive measures to prevent and address sexual harassment, including implementing effective policies, providing employee training and fostering a culture of respect and accountability. By doing so, we can create safer, healthier and more productive work environments for all the employees.

Design/methodology/approach

This study consisted of 344 individuals from the Syrian community who completed a questionnaire, that contained statements about harassment to gauge each gender’s perception and sensitivity toward it. The questionnaire was carefully designed to include 30 questions, including daily situations in the work environment that may occur and how they are classified by males and females. Is it harassment or not, and about the HR department have personal safety and security standards such as the code of conduct and the rules regulating these behaviors or not and our research project was a collaboration between the two nongovernmental organizations (NGOs): Stemosis and Institute of Human Resources Management (IHRM).

Findings

Our research reveals a distinction between the thinking patterns and coping mechanisms of females and males when it comes to dealing with this phenomenon. We presented various scenarios to our respondents, depicting situations that an individual might face in their everyday life and asked them questions related to the definition of harassment, its root causes and strategies for addressing it. Research has shown that women are at a higher risk of experiencing feelings of fear and dissatisfaction when subjected to sexual harassment. This unfortunate reality highlights the need for greater awareness and action to combat such reprehensible behaviors. Save Women!

Research limitations/implications

The study faced several limitations in collecting data due to the sensitive and shameful nature of the topic for both men and women in the Syrian Arab Republic. This caused embarrassment for some participants, leading to their unwillingness to participate in the research. Additionally, the study encountered difficulties in dealing with companies, as they did not accept exposure to such situations and failed to show any codes of conduct under the name of their company, and the participants did not consider certain factors as reasons for harassment. Specifically, 71.2% of participants did not consider inappropriate outfits as a reason for harassment. However, there was a significant difference between the opinions of men and women on this matter (p-value < 0.05). Additionally, political, social and psychological reactions were not considered a reason for harassment by 64.8% of participants.

Practical implications

In our study, there was a situation that one of the respondents (male) was exposed to by the HR manager (female) who was pretending to be a professional, after he confronted her, she threatened him with expulsion from work and despite his annoyance, he ignored her because it was pointless to talk with her and during the study, (44.7%) of the participants had experienced sexual harassment.

Social implications

Victims of sexual harassment experience a similar condition to post-traumatic stress disorder, which can lead to many mental and psychological issues. The overall organizational environment plays a critical role in the well-being of employees. It is widely accepted that victims of violence suffer from a lack of well-being. Employee well-being is based on feelings of happiness and satisfaction that come from a sense of security. According to the Maslow’s theory of needs, security is fundamental to people and a toxic workplace environment can destroy an individual’s sense of security, negatively impacting their well-being In Syria.

Originality/value

In Syria, society is considered closed about sexual issues and considers it a sensitive issue despite its presence and spread in work environments, as the results showed, and this is one of the challenges we face. Therefore, our study is the first in Syria and the largest that sheds light on this phenomenon clearly, strongly, deeply and directly.

Abstract

Purpose

With the advancement of technology, microlearning has emerged as a promising method to improve the efficacy of teaching and learning. This study aims to investigate the document types, volume, growth trajectory, geographic contribution, coauthor relationships, prominent authors, research groups, influential documents and publication outlets in the microlearning literature.

Design/methodology/approach

We adapt the PRISMA guidelines to assess the eligibility of 297 Scopus-indexed documents from 2002 to 2021. Each was manually labeled by educational level. Descriptive statistics and science mapping were conducted to highlight relevant objects and their patterns in the knowledge base.

Findings

This study confirms the increasing trend of microlearning publications over the last two decades, with conference papers dominating the microlearning literature (178 documents, 59.86%). Despite global contributions, a concentrated effort from scholars in 15 countries (22.39%) yielded 68.8% of all documents, while the remaining papers were dispersed across 52 other nations (77.61%). Another significant finding is that most documents pertain to three educational level categories: lifelong learning, higher education and all educational levels. In addition, this research highlights six key themes in the microlearning domain, encompassing (1) Design and evaluation of mobile learning, (2) Microlearning adaptation in MOOCs, (3) Language teaching and learning, (4) Workflow of a microlearning system, (5) Microlearning content design, (6) Health competence and health behaviors. Other aspects analyzed in this study include the most prominent authors, research groups, documents and references.

Originality/value

The finding represents all topics at various educational levels to offer a comprehensive view of the knowledge base.
