The purpose of this study is to examine the effect of entrepreneurial competencies on competitive advantage and to investigate the effect of competitive advantage on the performance of informal microenterprises owned and managed by women micro-entrepreneurs in Kelantan, Malaysia.

This study used a cross-sectional design and collected quantitative data from 384 informal women micro-entrepreneurs operating in “night markets” in Kelantan, Malaysia.

The finding of the analysis using variance-based structural equation modeling indicated that commitment competency, conceptual competency, organizing competency and opportunity recognition competency have a significant positive effect on competitive advantages, and competitive advantages have a significant positive effect on the performance of microenterprises owned and managed by women micro-entrepreneurs in Kelantan, Malaysia.

The development programs and policies should focus on improving the competencies, i.e. commitment competency, conceptual competency, organizing competency and opportunity recognition competency to improve the socioeconomic condition of low-income households in Malaysia. Informal women micro-entrepreneurs should, therefore, focus on value creating strategies to avoid potential competitors from duplicating the benefits of their strategy. This will result in a sustainable competitive advantage of microenterprises in Malaysia.

This study puts forward and tests the effect of entrepreneurial competencies on competitive advantages and performance of informal women micro-entrepreneurs in Kelantan, Malaysia, which provides a foundation for the design and implementation of development programs and policies that promote entrepreneurial activities in Malaysia.

The purpose of this study was to investigate how socio-religious dynamics influence (and are influenced by) principals in Islamic schools.

This qualitative case study took place in Semarang, Indonesia. Data were collected via semi-structured interviews with school leaders along with school site observations. To frame the study, we drew from both Indonesian and international scholarship to understand extant perspectives on the context and on the ways that principals influence socio-religious thinking and practices in schools.

Findings suggested that principals' personal experiences and beliefs are central to the ways that socio-religious thinking and practices are manifest in their school. Principals practice more progressive or conservative leadership by influencing the degree to which the school is (a) an open or closed system, (b) inclusive or exclusive in their practices and (c) plural or unitary in their teaching. In making decisions along each of these continua, principals in Islamic schools “curate” a socio-religious educational environment.

This paper contributes to the literature on principals and socio-religious dynamics in schools by discovering specific continua of practice that collectively suggest a more conservative or progressive interpretation of Islam. As this area is understudied in educational leadership, the study makes a foundational empirical contribution, suggests theoretical constructs heretofore unexplored, and advances the notion of principal as curator of educational practice.

This paper investigates the relationship between accounting and accountability practices in Muslim secondary schools in Tanzania using Bourdieusian perspective. The purpose of this paper is to address this issue.

In-depth interviews were conducted with school owners, teachers, accountants, an imam and leaders of Muslim organizations. Corroborative evidence was gathered through review of documentary sources. The data were analyzed using a mapping approach.

The findings show that powerful actors in the schools studied proactively selected accounting practices that supported their particular doxa of survival, access or legitimacy. Also, Fiisabilillah is identified as an existential doxa, and this was found to be more influential than individual accountability doxa and responsible for adherence to work among weak agents despite an inappropriate environment. As a result, accounting practices become “rhetoric” and play a minimal role in discharging both “sacred” and “secular” accountability to both human beings and God.

The findings suggest that accounting practices must be understood in the context of the socioeconomic and political settings in which the organization operates.

Most studies of accounting and accountability have focused on developed countries. This is one of the few studies to explore the phenomenon in the context of Muslim schools in a developing country.

This paper seeks to explore principals' leadership in successful Indonesian secondary schools from the perspectives of multiple sources of data.

Inspired by the ISSPP, three schools which met the set criteria of successful schools were selected to be the cases for this study. Within each, individual or group interviews were conducted with the principal, vice‐principal, three teachers, one support staff member, two groups of students, one group of parents, and the school committee president. The collected data were transcribed, coded and categorized following the emerging themes, and interpreted using inductive and deductive methods.

Whilst confirming several common practices of successful school leadership from earlier research, the principals from the three successful schools in Yogyakarta also demonstrated significant differences, particularly in terms of beliefs and values that underpinned their leadership. These values include Islamic and cultural beliefs and values which were strong and enduring, and which were articulated in the school leadership and strategies. The principals demonstrated ability in developing the school vision, setting strategies, building capacity, and establishing a broader network to achieve the benefits of school improvement.

The paper provides an insight into school leadership practices in the Asian context, particularly in Indonesian Muslim schools, which have suffered from a lack of attention from international researchers. The paper will also contribute to a worldview of successful school leadership characteristics and practices, the research into which has been piloted in the International Successful School Principalship Project (ISSPP).

The purpose of this paper is to validate the antimicrobial activity (both antibacterial and antifungal) of in vivo and in vitro ethanolic anthocyanin extracts of Clitoria ternatea L. (vivid blue flower butterfly-pea) and Dioscorea alata L. (purple yam) against selected bacteria (Bacillus subtilis, Staphylococcus aureus and Escherichia coli) and fungi (Fusarium sp., Aspergillus niger and Trichoderma sp.).

The freeze-dried samples (0.2 g) from in vivo vivid blue flowers of C. ternatea L. were extracted using 10 mL ethanol (produced ethanolic red extraction) and 10 mL distilled water (produced aqueous blue extraction) separately. Two-month-old in vitro callus samples (0.2 g) were only extracted using 10 mL ethanol. The anthocyanin extractions were separated with the addition (several times) of ethyl acetate and distilled water (1:2:3) to remove stilbenoids, chlorophyll, less polar flavonoids and other non-polar compounds. Furthermore, the antimicrobial properties were determined using agar diffusion technique. Three bacteria (B. subtilis, S. aureus and E. coli) and fungi (F. sp., A. niger and T. sp.) were streaked on bacteria agar and dextrose agar, respectively, using “hockey stick”. Then, the sterile paper discs (6 mm diameter) were pipetted with 20 µL of 1,010 CFU/mL chloramphenicol (as control for antibacterial) and carbendazim (as control for antifungal) in vivo and in vitro extracts. The plates were incubated at room temperature for 48 h, and the inhibition zones were measured.

Based on the results, both in vivo and in vitro ethanolic extracts from vivid blue flowers of C. ternatea L. showed the best antibacterial activity against the same bacteria (B. subtilis), 11 and 10 mm inhibition zones, respectively. However, different antifungal activity was detected in in vitro ethanolic callus extract (12 mm), which was against T. sp., contrary to in vivo ethanolic extract (10 mm), which was against F. sp.; antibacterial activity of D. alata L. was seen against the same bacteria (E. coli) with the highest inhibition zone for in vivo extract (8.8 mm), followed by in vitro extract (7.8 mm).

Anthocyanins are responsible for the water soluble and vacuolar, pink, red, purple and blue pigments present in coloured plant pigments. These pigments (pink, red, purple and blue) are of important agronomic value in many crops and ornamental plants. However, anthocyanins are not stable and are easy to degrade and fade whenever exposed to light.

Plant extracts containing bioactive agents with antimicrobial properties have been found to be useful in treating bacterial and fungal infections, as well as showed multiple antibiotic resistance.

Both in vivo and in vitro extracts from vivid blue flower petals (C. ternatea L.) and purple yam (D. alata L.) have important applications as natural antimicrobial (antibacterial and antifungal) agents in the coating industry, instead of natural pharmaceutical products.

Through description and consideration of 12 models developed as part of the International Successful School Principalship Project (ISSPP), a new model of successful school leadership is developed.

The paper is necessarily descriptive in nature. For the first time, 12 ISSPP models are described together, and these descriptions are then used inductively to create a new successful school leadership model.

The open systems approach adopted depicts schools as a continuous cycle of input-transformation-output with feedback loops that inform each stage of the cycle. The inputs are the variables that lead to transformation. The transformation stage is the actions or processes that individuals, groups and organisations engage in because of the inputs, and these lead to a range of student and school outcomes. Feedback loops connect the stages, and the whole model is open to the influence of five contextual forces: economic, political, socio-cultural, technological and system, institutional and educational.

Models are an important way to make sense of complex phenomena. A new model of successful school leadership, with an open systems approach, provides a different frame to consider the findings of the ISSPP and potentially allows the ISSPP research to inform practice and connect with other school leadership views in new ways.

This paper aims to study the effect of different organic solvents on the extraction of pigments present in callus cultures of E. cinerascens.

Attempts have been made to extract pigments from callus cultures through tissue culture system as an alternative replacement for conventional plant cultivation as tissue culture provides unlimited supplies of plant samples. Callus of E. cinerascens was induced from stem explant cultured in Murashige and Skoog medium supplemented with combination of 0.5 mg/L 6-benzylaminopurine and 0.5 mg/L α-naphthaleneacetic acid maintained under photoperiod of 16 h light and 8 h dark. Fresh samples of the callus were harvested and dissolved in various types and concentrations of solvents such as 100 per cent acetone, 80 per cent acetone, 95 per cent ethanol, 100 per cent methanol and 90 per cent methanol. Each of the mixtures was directly centrifuged to get clear supernatant containing pigments of interest. The pigments were detected and subsequently quantified via two simple techniques, ultraviolet-visible (UV-Vis) spectrophotometer and thin layer chromatography (TLC).

UV-Vis spectrophotometer detected two families of pigments present in the callus cultures, namely, carotenoids (carotene and xanthophyll) and tetrapyrroles (chlorophyll a and b). Pigment contents in various solvent extractions were estimated using spectroscopic quantification equations established. Through TLC, spots were seen on the plates, and Rf values of each spots were assessed to indicate the possible existence of carotenoids and tetrapyrroles.

This preliminary study offers significant finding for further advance research related on natural pigments extracted from E. cinerascens that would provide profits in the future applications, especially in food industry, medicine, agriculture, etc.

This study aims to investigate the relationship between young people’s Conspicuous Donation Behaviour (CDB) on social media platforms and their offline donation behaviour, specifically intentions to donate and volunteer time. It also explores materialism, self-esteem and self-monitoring as CDB trait antecedents, as a form of conspicuous consumption on social media. Finally, it considers the influence of altruism on these relationships.

A survey was conducted of regular Facebook users mentioning a charity brand on Facebook in the past year. Data from 234 participants were analysed and hypotheses tested using structural equation modeling.

Results confirm two forms of CDB – self and other-oriented. Materialistic consumers are more likely to engage in both forms of CDB on Facebook. High self-esteem increases self-oriented CDB; high self-monitoring increases other-oriented CDB. Self-oriented CDB is positively associated with donation intentions, but other-oriented CDB is negatively associated. Findings reveal how altruism moderates this model.

Findings show how personality traits influence CDB and reveal the relationship between CDB, as virtual conspicuous consumption on social media platforms, and donation behaviour.

The study provides implications for managers about enhancing charitable donations through social media.

This is the first study to explore donation behaviour as a form of conspicuous consumption on social media, where virtual conspicuous consumption (i) does not require any offline consumption and (ii) may achieve the desired recognition, without any charitable act. It provides new insights into CDB, its antecedents and influence on donation behaviour.
