AbstrakVanda hookeriana Rchb.f. merupakan anggrek yang dilindungi dan keberlangsungan hidupnya di alam terancam punah, sehingga perbanyakan anggrek secara in vitro sangat diperlukan. Penelitian ini bertujuan untuk mengetahui pengaruh ekstrak yeast dan pisang raja terhadap pertumbuhan tunas embrio anggrek V. hookeriana Rchb.f. Desain penelitian ini menggunakan RAL faktorial, faktor pertama adalah ekstrak yeast dengan 3 taraf: 0,5 g/L, 1 g/L, dan 1,5 g/L, faktor kedua adalah buah pisang raja dengan 3 taraf: 50 g/L, 100 g/L, dan 150 g/L. Penelitian dilakukan menggunakan teknik kultur jaringan, pengamatan dilakukan setiap bulan sekali dengan mengamati aspek morfologi plantlet. Media yang digunakan adalah Vacin-Went (VW) + kombinasi ekstrak yeast dan pisang raja. Parameter pengamatan berupa tinggi tunas, berat kering tunas, jumlah daun, diameter daun, panjang daun, berat kering daun, jumlah akar, diameter akar, panjang akar, berat kering akar, dan morfologi tunas. Hasil analisis menunjukkan bahwa perlakuan pisang raja 150 g/L + ekstrak yeast 0,5 g/L merupakan konsentrasi yang paling berperan terhadap parameter pertumbuhan anggrek V. hookeriana Rchb.f. Penelitian ini berhasil membuktikan bahwa penambahan komponen organik dalam media kultur jaringan memberikan respon pertumbuhan dan perkembangan yang baik pada eksplan. Komponen organik membantu proses fisiologis eksplan, karena komponen organik mengandung senyawa potensial yang dibutuhkan selama proses pertumbuhan dan perkembangan. Abstract Vanda hookeriana Rchb.f. is one of protected orchid and its survival in the wild was threatened by extinction, so orchid propagation was needed. This research aimed to determine the effect of yeast and pisang raja extracts to embryonal shoot growth of Vanda hookeriana Rchb.f. Experimental design used factorial RAL, first factor was yeast extract with 3 treatments (0.5 g/L; 1 g/L; & 1.5 g/L). Second factor was pisang raja with 3 treatments (50 g/L; 100 g/L; & 150 g/L). The research was conducted using in vitro culture techniques, observations were made once a month by observing the plantlet morphological parameters. The medium used was Vacin-Went (VW) + combination of yeast and pisang raja extracts. Observation parameters were shoot height, shoot dry weight, leaf number, leaf diameter, leaf length, leaf dry weight, number of roots, root diameter, root length, root dry weight and shoot morphology. The analysis showed that pisang raja treatment 150 g/L + yeast extract 0.5 g/L was the best concentration for the growth parameters of Vanda hookeriana Rchbf. This research were succeeded in proving that the addition of organic components in tissue culture media gave better response to growth and development of the explants. Organic components helps the explants in physiological ways because of the organic components contain potential compounds needed during the growth and development process.

Senyawa bioaktif pada madu dan Aloe vera dapat membantu meningkatkan pembentukan kolagen. Penelitian ini dilakukan untuk membandingkan pengaruh aplikasi topikal madu, gel Aloe vera, dan Moist Exposed Burn Ointment (MEBO) terhadap kepadatan kolagen pada proses penyembuhan luka bakar derajat dua pada tikus. Luka bakar dibuat pada 28 ekor tikus dan dibagi menjadi empat kelompok yang dipilih secara acak serta dilakukan aplikasi topikal harian dengan NaCl, madu, gel Aloe vera, dan MEBO secara berurutan. Biopsi kulit dilakukan pada hari ke-7, kemudian dilakukan pembuatan sediaan histopatologi kulit dan dihitung kepadatan kolagennya. Uji One Way ANOVA menunjukkan kepadatan kolagen berbeda secara signifikan antar masing-masing kelompok (p= 0,009). Uji Post Hoc Bonferroni menunjukkan terdapat perbedaan yang signifikan antara kelompok NaCl dengan madu (p= 0,024) dan NaCl dengan MEBO (p= 0,024). Penelitian ini menunjukkan bahwa aplikasi madu dan MEBO secara topikal pada luka bakar derajat dua dapat meningkatkan pembentukan kolagen, sehingga dapat mempercepat proses penyembuhan luka. Madu, Aloe vera, dan MEBO dapat dijadikan sebagai terapi alternatif dalam penyembuhan luka bakar. AbstractVarious scientific studies have proven that collagen is an ideal biomaterial in wound healing activities. The bioactive compounds in honey and Aloe vera can help increase collagen formation. This study was conducted to compare the effect of topical application of honey, Aloe vera gel, and MEBO (Moist Exposed Burn Ointment) on collagen density in the healing process of second-degree burns in rats. Burns were made on 28 rats which were further randomly divided into four groups to receive daily topical application of NaCl, Aloe vera, honey, and MEBO respectively. Skin biopsy was carried out on the seventh day, then histopathological preparation of the skin was made and collagen density was calculated. Result of One Way ANOVA test showed that collagen density differed significantly between groups (p= 0.009). The Post Hoc Bonferroni test resulted in significant difference between NaCl with honey group (p= 0.024) and NaCl with MEBO (p= 0.024). This study found that topical application of honey and MEBO to second-degree burns could increase collagen formation, thus accelerating wound healing process. Honey, Aloe vera, and MEBO can be used as alternative therapies for healing burns.

Introduction: Mesenchymal stem cells (MSCs) and platelet-rich plasma (PRP) have a potential role in improving wound healing processes. This experimental study aims to compare PRP and MSCs to promote the wound healing process in the animal burn wound model.
Methods: PRP from venous blood and MSCs from lipoaspirates were isolated from six donors. Saline solution was used as control while PRP and MSCs as treatment groups were injected to second-degree burn wounds in the backs of 10 male Sprague-Dawley rats for each group. On day 7, 5 rats from each group were euthanized for analyses VEGF gene, which has a role in angiogenesis. At the end of the study (week 5), the remaining rats were euthanized for histological analysis.
Results: The VEGF expression in MSCs and PRP groups was higher than the control group (not significant). The wound healing rate was also significantly faster until 21 days post-burn in the MSCs and PRP groups and getting slowly afterward. Histological analysis showed the burned skin at day 35 had displayed the best differentiation outcome in the MSCs group. In conclusion, human-derived MSCs and PRP do not accelerate epithelialization duration of rats burn wound model. However, they improved wound’s vascularization and cell differentiation.
Conclusion: MSCs are superior to PRP in enhancing cell differentiation.
The Analytical Metaphysics of Time and the Recent Theory of History
Authors: Cardoso Jr. Hélio Rebello 
Published: May 2021

The longstanding line of research that the analytic tradition calls metaphysics of time remains quite ignored by the theory of history. To bring them closer, this study proposes to introduce to historians and theorists of history the metaphysics of time theses about the presentism/eternalism and the linear/closed time. For such purpose, we drew correspondences between the theory of history and the analytical metaphysics of time concerning some characteristics of the emerging concepts of historical time. These characteristics are related to the recent debate about presentism regarding the regimes of the historical time (multiple temporalities and pluritemporality); plural time in the analytical metaphysics and synchronous/asynchronous historical time; linear/closed time in the analytic tradition and being affected by historical time. As a result, this article presents how the analytical metaphysics of time theses disclose unnoticed contours related to the history theorists’ understanding about the relation with the past.
“I Think I’m the Bridge”: Exploring Mentored Undergraduate Research Experiences in Critical Multicultural Education
Authors: Bybee Eric Ruiz , Whiting Erin Feinauer , Cutri Ramona Maile 
Published: May 2021

Although mentored undergraduate research has been shown to deepen student engagement across various disciplines, this type of extended learning opportunity is not a prominent feature of research and practice in teacher education. Our article addresses this gap by analyzing the experiences and growth of a group of five preservice teachers engaged in a mentored undergraduate research experience in several sections of an introductory critical multicultural education course. Specifically, we examined how pre-service teachers’ personal, academic, and professional engagement with critical multicultural education is impacted when they are positioned as researchers and receive additional training outside the traditional class format. Our findings indicate that their involvement as student co-researchers fostered a new awareness, sensitivity, and emotional investment in issues of social justice beyond what they gained in their introductory multicultural education course. Pre-service teachers described navigating personal relationships with new awareness and sensitivity and adjusting future plans in accordance with their deeper understanding and commitment to educational equity. We argue that mentored research opportunities are an innovative way to address professor/student power differentials in teacher education research and offer a unique model of critical multicultural teacher education that promotes deep engagement with issues beyond the classroom setting.
The Hidden Curriculum of Monolingualism: Understanding Metonymy to Interrogate Problematic Representations of Raciolinguistic Identities in Schoolscapes
Authors: Przymus Steve Daniel , Huddleston Gabriel 
Published: May 2021

Choices regarding how signs are displayed in schools send messages regarding the status of languages and speakers of those languages. The monolingual paradigm can be implicitly reified by the position, shape, color, etc. of languages in relation to English on school signage (Author & Co-author, 2018). This can have a negative impact for culturally and linguistically diverse youth. In combining critical race media literacy with linguistic landscape research, we uncover a hidden media of raciolinguistic ideologies (Alim, 2016), and confront the hegemony found on some of the most overlooked and under questioned representations of media - signs in schools.
Incorporating the Critical Music Framework: An Autoethnographic Reflection
Authors: Ender Tommy 
Published: May 2021

I articulate an autoethnographic narrative of using different songs to counter dominant interpretations of gender, class, immigration, slavery, and education in the social studies classroom. Framing it as the Critical Music Framework, the practice of using music addressing social issues and historical representations of women and people of color provided secondary students with reflective, learning opportunities. The resulting conversations illustrate the importance of music not just on the personal, but also the academic aspects of individuals.
Earnings shocks: An event study on Boursa Kuwait
Authors: AlHajraf Saad B F M 
Published: May 2021

This study investigates the effects of earnings announcements on stock prices in Boursa Kuwait, formerly known as the Kuwait Stock Exchange (KSE). The data spans the period 2018–2020, and both positive and negative earnings announcements are employed as shock events and their effects assessed. The study results show that there is a statistically abnormal rate of return before and after the earnings announcements and that most abnormal returns are just after the earnings announcement. This most likely indicates that Boursa Kuwait is a semi-strong efficient stock market. One important implication is an indication that insider-related trading might be absent in Boursa Kuwait.
Examining the competitiveness of banking sector in Sri Lanka
Authors: Liyanagamage Champika 
Published: May 2021

The banking sector in Sri Lanka has been portrayed by significant changes in the past few decades. It is widely perceived that competition in the Sri Lankan banking sector has improved since the introduction of the financial sector reforms in the 1990s. By applying Panzar-Rosse (PR) approach to test the degree of competitiveness, this paper assesses the validity of this claim in the context of the Sri Lankan banking sector during 1996-2018. The sample covers a broader set of bank-level panel data of the whole commercial banking sector which comprised of 25 licensed commercial banks. The EGLS procedure applied in this study revealed that during the stated period, the Sri Lankan banking sector had been moderately competitive. Further analysis also disclosed that there is no significant difference between the state-owned banks and private banks regarding their degree of competitiveness, as well as their temporal dynamics. Another striking observation revealed in this analysis is the lower level of competitiveness among foreign banks compared to the competitiveness of local banks. The Competitiveness of the Sri Lankan banking sector however is characterized by non-price competition, as on many occasions the interest rate depends on government policies. Hence, this study provides new insight into the nature of financial sector competitiveness in underdeveloped countries. The outcome of the research implies the necessity of attempts of all banks towards re-aligning their strategies to attract and retain customers. This would be the major challenge that banks face in accomplishing a higher level of competition in the banking industry in the future.

Published: May 2021

The Micro Small and Medium Enterprises (MSMEs) are important for every nation’s economic development. They provide employment and spur the growth of multiple sectors in the economy. The Covid-19 pandemic has negatively affected MSMEs' performance. The study seeks to demonstrate why COVID 19 may lead to the terminal quarantining of MSMEs. The study is anchored on decision usefulness and information asymmetry theories. The study adopted a descriptive research methodology and sampled MSMEs within Nairobi City County. The study used SPSS to analyze data in addition to Microsoft excel. The study found that over 70% of MSMEs had their sales decline by over 65% while 95% of them had their sales decline by over 30%. The study found that about 68% of MSMEs lacked financial management skills. The study recommends that with legal and institutional reforms, the government needs to develop a financing framework for MSMEs.

Published: May 2021

Organizations regardless of type, structure, size, among other factors may have similar foundations in the development of HR policy but applicable factors for consideration may vary. Among the most common factor in the development of an HR policy is the culture of the organization. In making sure that the DWEA core values are working within the person in SVD educational institutions, it became the aim of this study to come up with an HR model that would be functional and best support the vision, mission, and goals of all Northern, Central and Southern SVD schools in the Philippines. Specifically, this study determined the level of integration and implementation of organizational leadership and excellence towards 3 HR practices namely: employee relations, performance appraisal, and work-life balance. While the results show that organizational leadership and excellence are integrated and implemented in the 3 human resource practices namely employee relations, performance appraisal, and work like balance, it is highly recommended that the administrators of the different SVD educational institutions must review the integration of the moderately rated practices in its employee relations, performance appraisal, and work-life balance in order to recalibrate its existing systems. Furthermore, those integrated but moderately implemented should likewise be appraised for full implementation.
