Foreign Ownership, R&D and Firm Innovation in ASEAN Countries: A Generalized Ordered Logit Model
Authors: Nguyen-Van Dung , Chang Chia-Hua
Published: February 2020

The study investigates the direct effects of foreign ownership and R&D on firm innovation and the moderating effects of R&D on the foreign ownership–innovation relationship in ASEAN countries. This research focus is important as ASEAN countries have received a large amount of inward FDI as part of their export-led growth strategy, and FDI can bring both benefits and negative impacts for the host country. To the authors’ knowledge, this study contributes as the first attempt to examine this topic in ASEAN. The study employs a novel approach (i.e., generalized ordered logit model (GOLM)) to deal with the restrictive “parallel regression/proportional odds” assumption of the standard ordered logit model (OLM), which has not been adequately addressed in previous studies on the foreign ownership–innovation relationship. The findings show that foreign ownership relates negatively to the possibility of radical innovation, while R&D relates positively to the possibility of radical innovation. In addition, R&D positively moderates the effect of foreign ownership on the possibility of radical innovation. The findings verify the important role of R&D as a mechanism for absorptive capacity building in the foreign ownership–innovation relationship, which has been under-researched in prior studies on the role of foreign ownership in firm innovation. The policy implications emphasize that ASEAN governments should have more technological regulations and incentives to encourage foreign investors to bring advanced technologies and invest more in R&D.

Published: February 2020

Small and medium enterprises (SMEs) have been considered as one of the engines of economic growth, sustainability, and industrial development of a nation, however, the survival rate of SMEs in Nigeria has been seriously affected by the volatile environment in which they operate. The use of survival strategies has also been one of the major challenges facing the business since most people believe that strategies are only meant for large and multinational companies. This study, therefore, examines the survival strategies and sustainability of small and medium enterprises in a volatile business environment using a quantitative approach. The data were administered through a questionnaire to 350 respondents from small and medium enterprises in Lagos State, Nigeria. The questionnaire was analyzed with the use of the Structural Equation Model. The results reveal that there is a significant and positive relationship between survival strategies and sustainability of small and medium scale enterprises in Nigeria.

Published: February 2020

Modern gas turbine engines operate under changing temperature loads. Therefore, one of the important characteristics of the protective coatings used on the turbine blades is their high resistance to the occurrence and development of cracks under mechanical and thermal loads. The applied effective systems of internal heat removal of the cooled turbine blades lead to an increase in their heat stress. At present, cracks arising from thermal fatigue are one of the common defects of the protective coatings used on turbine blades. The heat resistance of coatings at high temperatures is determined by three factors: the shape of the part on which the coating is applied, the thickness of the coating and the phase composition of the surface layers or the maximum aluminum content in the coating. Therefore, when choosing a protective coating for these operating conditions, it is important to know the impact of these factors on the thermal stability of the coating. The paper presents a comparative study of various coatings on their resistance to crack formation under cyclic temperature change. The dependence of the heat resistance of the considered coatings on the method of their application and phase-structural state is established. Especially valuable is the established mechanism of formation and propagation of thermal fatigue cracks depending on the phase composition of the initial coating. It is shown that the durability of protective coatings with cyclic temperature change depends on the chemical composition of the coating and the method of its formation. The dependence of the formation of thermal fatigue cracks on the samples with the coatings under study on the number of cycles of temperature change is established.
Do Affirmative Action Bans Cause Students to Move Across State Lines to Attend College?
Authors: Hinrichs Peter L.
Published: February 2020

This Economic Commentary studies whether statewide bans on affirmative action in admission to public universities cause students to move to a new state to attend college. Regression results using data from the decennial census and the American Community Survey provide little evidence that affirmative action bans result in migration across state lines to attend college. In addition to being of direct interest, these results provide a check on earlier research that treats different states roughly as separate higher education markets.
Corporate Vocational School: Strategi Antisipatif Menghadapi Pengangguran Lulusan SMK dalam Perspektif Bonus Demografi
Authors: . Tarma
Published: February 2020

Pengangguran merupakan salah satu ancaman menjelang fenomena bonus demografi. Institusi pendidikan vokasi bertanggung jawab mengantisipasi hal tersebut. Sekolah Menengah Kejuruan (SMK) yang diharapkan menjadi solusi, justru menempatkan lulusanya menjadi kontributor terbesar pengangguran sebesar 11,19% (data BPS tahun 2013). Pengangguran lulusan SMK disebabkan oleh kesenjangan antara tenaga kerja dengan kebutuhan penyedia lapangan pekerjaan. Untuk itu diperlukan "corporate vocational school", yaitu konsep sekolah kejuruan yang dimiliki perusahaan serta terintegrasi dan in line dengan manpower planning yang ada di perusahaan tersebut. Konsep "corporate vocational school" merupakan down grade dari konsep "corporate university" yang sudah lebih dulu eksis. Dalam corporate vocational school, bidang keahlian yang dipelajari sesuai dengan core business perusahaan. Kultur akademik terintegrasi dengan kultur kerja perusahaan. Model pembelajaran dirancang dengan work real life based. Standar lulusan sesuai dengan kriteria minimal atau job requirement dari posisi pekerjaan yang telah diproyeksikan sebelumnya. Sehingga lulusan dari sekolah ini langsung dapat diserap serta langsung tune in dengan pekerjaan.

Background: Denture hygiene habits are liable to change from one person to another. There has been a close relationship between irregular denture surfaces, poor oral hygiene or ill-fitted denture and opportunistic oral microorganism which leads to diseases like denture induced stomatitis.
Case Presentation: A 70-year-old patient reported to the Department of Prosthodontics with a chief complaint of broken denture and pain in oral mucosa. The patient history, oral and denture examination indicated that the patient had denture stomatitis.
Management & Results: The patient was advised to have good oral hygiene and anti-microbial gels. After a week of follow up, the patient showed good results with the treatment.
Conclusion: It can be concluded that the patient needs to be educated regarding denture and oral hygiene is the most important step to prevent this type of disease.
Oxidative stress mediated neurodegeneration; A cellular perspective
Authors: Noushad Shamoon , Sajid Ujala , Ahmed Sadaf , Saleem Yusra
Published: February 2020

Background: Environmental toxins, nutritional discrepancies, genetic predispositions, and lifestyle modifications induce a variety of stresses on the human brain and body. Such chronic stressors can influence the onset and progression of neurodegeneration via cellular alterations. In this systematic review, we have discussed the role of oxidative stress in causing neurodegeneration. Moreover, the chemical, metallic and other etiological factors that stimulate oxidative stress and results in the development of neurodegenerative disorders are also explored and summarized.

Methodology:  A systematic review was conducted to investigate the impact of oxidative stress on the human brain in relation to neurodegeneration. The human studies focusing on neurobiology and cellular changes in brain, investigating the pathway of oxidative stress leading to neurodegeneration through mitochondrial dysfunction and cellular alterations, published during 1st January 2000 to 31st March 2019 were identified and included in this systematic review.

Result: Following the PRISMA guidelines, 13 out of 1169 studies met the eligibility criteria and were included in the quantitative synthesis and screening. These studies focused on the features like cellular factors, metal exposure, and aging, inducing oxidative stress-related neurodegeneration. 6 studies described mitochondrial alterations resulting in oxidative stress due to an increase in the production of reactive oxygen species (ROS), oxidation of proteins, peroxidation of lipid and damages to the deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). While the data from 5 studies suggested the loss of mitochondrial activity in response to metal exposure. 2 experimental studies specified the effect of aging and self-implication of oxidative stress in the brain.     

Conclusion: Although there are sufficient evidence that supported the hypothesis that stress is significantly associated with neurodegeneration but it is still not considered as a primary instigator in neurodegenerative disorders. However, it can be concluded on the basis of this review that it has been involved in the propagation of cellular alterations and mitochondrial dysfunction that further leads to neurodegeneration.

Background: Pain is a complex phenomenon for which many pharmacological agents have been discovered and utilized for pain relief. Ketamine is a more preferred pain reliever over opioids in the emergency department (ED). The aim of this study was to compare the safety and efficacy of low dose ketamine (LDK) with morphine (opioid) for pain relief among patients presenting to the ED.

Methodology: A prospective, cohort study was conducted over a sample of 280 patients presented with acute pain to the ED, Ziauddin University Hospital, Karachi. These patients were then divided into two groups via simple random sampling with randomization being assured using an online randomizer software tool. The 1st group (n=140) was given 0.2 mg/kg of LDK while 0.1 mg/kg of intravenous morphine (opioid) was given to the 2nd group (n=140). The pain intensity was measured using the Visual Analogue Scale (VAS) from admission to 60 mins, the records were taken after every 15 mins. The adverse events (AE’s) were also recorded for both groups. The data was then analyzed using SPSS Version 21 & Microsoft Excel 2016.

Results: Out of 280 patients enrolled in the study, there was male majority i.e. 76.07% while the remaining were females with the mean age of 29±7 years. Within 15 minutes of initial dose administration in both groups, a marked reduction in pain intensity was observed. Reduced respiratory rate, pruritus and decreased O2 saturation were common AE’s observed, which were comparatively higher among patients receiving morphine as compared to ketamine.

Conclusion: The efficacy of morphine (opium) and LDK is similar in alleviating pain in an emergency setting, however, LDK is visibly safer than its opioid counterpart and thus may be used as a safer alternative.
