The purpose of this paper is to numerically investigate the flow characteristics and extend the data of friction factor and Reynolds number product of hydrodynamically developing laminar flow in three-dimensional rectangular microchannels with different aspect ratios.

Using a finite-volume approach, the friction factor characteristics of Newtonian fluid in three-dimensional rectangular ducts with aspect ratios from 0.1 to 1 are conducted numerically under no-slip boundary conditions. A simple model that approximately predicts the apparent friction factor and Reynolds number product f_appRe is referenced as a semi-theoretical fundamental analysis for numerical simulations.

The accurate and reliable results of f_appRe are obtained, which are compared with classic numerical data and experimental data, and the simple semi-theoretical model used and all comparisons show good agreement. Among them, the maximum relative error with the classic numerical data is less than 3.9 per cent. The data of f_appRe are significantly extended to other different aspect ratios and the novel values of f_appRe are presented in the tables. The characteristics of f_appRe are analyzed as a function of a non-dimensional axial distance and the aspect ratios. A more effective and accurate fourth-order fitting equation for the Hagenbach's factor of rectangular channels is proposed.

From the reliable data, it is shown that the values of f_appRe and the model can be references of pressure drop and friction factor for developing laminar flow in rectangular channels for researchers and engineering applications.

Dementia is characterized by the progressive decline in cognitive and daily functioning. Although the decline is often the defining characteristic of dementia in biomedical models, several scholars highlight the preserved skills of persons with dementia. Identity, or a sense of self, is among the areas relatively preserved in the later stages of dementia. It is the window through which caregivers understand the subjective experiences of persons with dementia.

This qualitative exploratory study highlights the value of social relationships, particularly the role of the Filipino family in recognizing personhood and maintaining identity in dementia care. Preserving identity entails understanding the person’s unique characteristics that reflect one’s sense of self. In a highly collectivistic culture, such as the Philippines, the family is crucial to preserving identity and overall well-being in dementia. This study explores the perspectives of 15 Filipino caregivers as regards caring for a family member with dementia. Participants discuss changes in family structure and the challenges in dementia care. More importantly, they delve into strategies used to preserve identity and encourage life participation in their loved one with dementia. Essential Filipino cultural values in dementia care, such as collectivism, religion, and the values of filial piety and utang na loob (or debt of gratitude) are further discussed.

The purpose of this paper is to offer novel insights into: knowledge of proto-feminism through description and analysis of the rule of the seventh century female Emperor Wu Zetian; postcolonial theory by revealing the existence and proto-feminist activities of a non-western female leader; and the literature on gender and invisibility through a study of a leading figure that is relatively unknown to western feminists and is even, in feminist terms, something of a neglected figure.

In order to examine Wu’s proto-feminist practices as recorded in historical materials, we use critical hermeneutics as a tool for textual interpretation, through the following four stages: choosing texts from historical records and writings of Wu; analyzing the historical sociocultural context; analyzing the relationship between the text and the context; and offering a conceptual framework as a richer explanation.

Wu’s life activities demonstrate proto-feminism in late seventh century China in at least four aspects: gender equality in sexuality, in social status, in politics, and women’s pursuit of power and leadership.

Future research may dig into the paradox of Wu’s proto-feminist practices, the relationship between organizational power and feminism/proto-feminism, and the ways in which Wu’s activities differ from other powerful women across cultures, etc.

The study encourages a rethink of women and leadership style in non-western thought.

The study supports Calás and Smircich’s 2005 call for greater understanding of feminist thought outside of western thought and a move to transglobal feminism.

This study recovers long lost stories of women leadership that are “invisible” in many ways in the historical narratives, and contributes to postcolonial feminism by revealing the existence of indigenous proto-feminist practice in China long before western-based feminism and postcolonial feminism emerged.

management practices in a Russian Multinational Company (RMC). The paper is motivated by the lack of empirical evidence on financial management practices outside the Western World (especially from Russia and from other Commonwealth of Independent States). Data for the analysis are gathered from documents and in‐depth interviews with finance managers in the company. The findings of the paper suggest that the company implemented an international cash management system reminiscent of international cash management discussed in the Western literature. For example, techniques such as netting, leading and lagging, re‐invoicing center and cash flow planning are used in the company. Thus, our conclusion is that financial management techniques are likely to be the same in Russia as in the Western world. However, differences are likely to be found in the ways in which these techniques are implemented and used in practice due to differences in environmental conditions. For example, the company did not use any of the sophisticated cash management models discussed in the literature. Our research has implications for understanding financial management practices outside the Western World, especially in Russia.

The purpose of this paper is to study the different effects of second home tourism development and its comparative analysis from the view of owners and residents in Shirin- Dareh Region of Iran.

Applied methodology is based on empirical studies and descriptive-analytical methods. In order to do this, seven rural areas were selected with 1,188 households as the volume of sample society by Cochran formula, and 218 questionnaires were distributed between them in two groups of owners and residents.

There is a strong correlation between second home tourism development and changes in social, economic, physical and environmental dimensions. The impact of the variable of the second home tourism development on changes in rural life was approximately 0.449 which reveals the average impact of second home tourism in the study area. Investments by none-indigenous with a co-efficient of 41.8 per cent have had the greatest role in different changes in rural life.

The generalizability of results to other countries is limited.

This study and studies similar to it have led to adopted comprehensive approaches to tourism and second homes in Iran and other Third World countries.

This paper contributes to the literature by including socio-economic variables in the domestic tourism and second home model. So this paper has a new subject and in practical aspects it tries to take a general solution to second home tourism on rural settlements development in Iran.

This chapter examines the life histories of selected teenage Filipino fathers relative to their experiences of dating, courtship, and the discovery, engagement, and experimentation with risk-taking behaviors such as smoking, drinking alcohol, and premarital sex. Using an interpretative phenomenological analysis (IPA), this study conducts family genogram and in-depth semi-structured interviews among eight teenage fathers. In so doing, it interrogates the consequences of sexual behaviors to the well-being of their respective families of orientation as well as the future of their expected family of procreation. The chapter argues how the risks of teenage fatherhood in the Philippines are relatively mitigated by the general conservative culture of Filipino families and the Catholic sense of religious orientation that seems to provide resilience captured in three themed experiences of “natauhan” (realization), “pinangatawanan” (accountability), and “pinanindigan” (owning responsibility). Thus, this chapter unravels the voices of young Filipino teenage fathers who straddles, on the one hand, the risk of premarital sex and pregnancy, and on the other hand, the challenges of responsible parenthood. In conclusion, the chapter provides policy insights on sex education and gender equality training for the vulnerable Filipino youth in the country.

Demographic and health surveys in the Philippines have shown a rise in cohabitation among young people. This chapter aims to provide an in-depth sociological understanding of a more specific phenomenon called serial cohabitation – referring to the dissolution of current cohabitation and entering a new one, and the continuation of the cycle if the new one ends again. By developing the framework of undisplaying and re-displaying family from Janet Finch’s displaying family, this study posits that serial cohabiters experience a cycle of wanting to display an ideal family and having to undisplay every time the dissolution of the cohabiting relationship happens. This study demonstrates how serial cohabiters with children, in response to social stigma, exhibit resiliency toward stepfamily formation and committed sexual relationships. This chapter, therefore, conceptualizes “family acceptance” which refers to embracing the fluidity, reconfigurations, and “imperfections” of their newly formed family and “community acceptance” which covers the same affirmation from friends, neighbors, and extended relatives who are considered as relevant others by serial cohabiters. Family acceptance comes in three forms: first is the acceptance of/by children, second is the acceptance by the parents to the repeated stepfamily formation within their own homes, and third is the acceptance of the woman herself to the possibility that cohabitation is the “happy ever after.” This study argues that once these forms are achieved, serial cohabiters become more capable of undisplaying their previous family and displaying their new family.

The purpose of this paper is to investigate factors affecting e-banking usage based on electronic service (e-service) quality, attitude and customer satisfaction.

A conceptual model to investigate factors that influence e-banking usage was developed based on review of existing literature. The model employed e-services quality variable, diffusion of innovation construct and self-efficacy to better reflect the users’ views of e-banking usage. Data collected from 254 e-banking users were used to test the model. The data were analysed based on PLS-SEM using SmartPLS 3.0.

The result reveals that perceived e-service quality has a strong influence on customer satisfaction and use of e-banking, which means that greater quality of e-service has the potential to increase satisfaction and consequently result in to more use of e-banking. In this research findings, competence of e-service support staff, system availability, service portfolio, responsiveness and reliability, in that order, were found to be most significant in rating e-service quality.

This offers financial institutions and professional relevant information e-banking services that will promote greater customer satisfaction and use of e-banking.

This paper contributes to knowledge advancement in bank marketing by providing insight into motivational factors of e-banking services quality and personal characteristics.

The purpose of this study is to examine the effects of inclination angle on the thermal energy storage capability of a phase change material (PCM) within a disc-shaped container. Different container materials are also tested such as plexiglass and aluminium. This study aims to assess the energy storage capacity, melting behaviour and temperature distributions of PCM with a specific melting range (22°C–26°C) for various governing parameters such as inclination angles, aspect ratios (AR) and temperature differences (ΔT) and compare the melting behaviour and energy storage performance of PCM in aluminium containers to those in plexiglass containers.

A finite volume approach was adopted to evaluate the thermal energy storage capability of PCMs. Five inclination angles ranging from 0° to 180° were considered and the energy storage capacity. Also, the melting behaviour of the PCM and temperature distributions of the container with different materials were tested. Two different AR and ΔT values were chosen as parameters to analyse for their effects on the melting performance of the PCM. Conjugate heat transfer problem is solved to see the effects of conduction mode of heat transfer.

The results of the study indicate that as AR decreases, the effect of the inclination angles on the energy storage capacity of the PCM decreases. For lower ΔT, the difference between the maximum and minimum stored energies was 20.88% for AR = 0.20, whereas it was 6.85% for AR = 0.15. Furthermore, under the same conditions, the PCM stored 8.02% more energy in plexiglass containers than in aluminium containers.

This study contributes to the understanding of the influence of inclination angle, container material, AR and ΔT on the thermal energy storage capabilities of PCM in a novel designed container. The findings highlight the importance of AR in mitigating the effect of the inclination angle on energy storage capacity. Additionally, comparing aluminium and plexiglass containers provides insights into the effect of container material on the melting behaviour and energy storage properties of PCM.
