Published: May 2019

In this modern world where everything is connected with new technologies and internet. Under control of the internet and new technological inventions, it is hard to undermine their contribution to foreign language teaching. This study pertains to the beginner level students doing English language diploma courses in their initial stage at a private English learning institute located in Sindh province of Pakistan. The study aims at investigating English teaching practices through SS method (Student to student) such as pair work and group study and reduce TS method (Teacher student) of teaching. In such methods modern technology such as visualizer and multimedia (modern technology) are great help for practicing a language teaching. The use of aids and tools is one of the useful resources for language learning and teaching in an easy manner. Most of the researchers’ interest lies in action research and carried out different cycles of action research such as planning, acting, observation and reflection. The study used convenient sampling to recruit participants (n=20). Data for the study included open-ended questionnaires, classroom observations and semi –structured interviews from students as well as researchers’ reflections as a supplementary source of data. The study finds multimedia usage crucial, especially by the young generation of language teachers who understand and support the idea of technology in the classroom, on the contrary to the older generation which criticizes and underestimates its importance.

This special issue of RETERM – Thermal Engineering is the continuation of the brazilian thermal science community’s effort to bridge the gap between the scientific (academia) and industrial communities. For that, the journal continues to be divided in two main sections: science and technology. The former is directed to publish complete articles that deal with fundamental advances in heat transfer and fluid mechanics, new physical insights, and novel experimental and analytical methods that have great appeal for the industry community, and the latter is designed to comprise informative articles that document modern engineering applications, or general advances in industry. Particularly, in this special issue, the best articles written in English language, presented at the I Brazilian Congress of R&D in Oil and Gas, held in Natal, RN, between November 25th and 28th, 2001, were selected by the Associate Technical Editors of RETERM, according to the scientific criteria of the journal. This way, RETERM specifically addresses the Oil and Natural Gas sector, that has been fomented by the existing great needs and by the existence of CTPETRO – Brazilian National Plan of Science and Technology for the Oil and Natural Gas Sector, that plays a role of crucial importance on fomenting scientific research in Brazil. The institutional support from the Brazilian Society of Mechanical Sciences (ABCM), and from the Brazilian Society of Industrial Machinery and Equipments (ABIMAQ), continues to strengthen our belief in the success of this enterprise. To open a perspective to the maintainance and continuity of RETERM, we invite the readers from the industrial community to contact our staff for subscriptions and publicity in RETERM. For the next issues we continue to welcome technical articles from both the scientific and the industrial communities to either section of RETERM, and contributions to the other sections of the journal, and suggestions for new sections as well. We also welcome response and comments from our readers that will eventually help the success of RETERM.

Published: May 2019

Fraud has always remains an issue for organisations throughout the globe due to the increasing number of fraud occurrences over the years which resulted to the increasing amount of losses. Despite the large amount of efforts by organisations through internal control implementation and the amount of money spent to combat fraud, the numbers of fraud occurrences are still increasing. This study examines the employees’ intention to commit fraud. Specifically, this study examines the influence of perceived pressure and perceived opportunity on employees’ intention to commit fraud. In addition, this study examines the effect of capability in moderating the influence of perceived pressure and perceived opportunity on employees’ intention to commit fraud. Using online questionnaire on 158 employees from various sectors, this study shows that the employees have a low intention to commit fraud. This study also shows an existence of linear relationship between perceived pressure and perceived opportunity on employees’ intention to commit fraud. Consistent with previous studies, this study found that capability of the employees does not influence them to commit fraud. The findings in this study assist the employers to adopt appropriate strategies in preventing and detecting fraud possibility among their employees.

Authors: Ab Samad Nur Hayati Binti , Md Yusoff Noreena , Ismail Rina Fadhilah
Published: May 2019

In order to successfully accomplish the social and business mission, social enterprises need to identify the appropriate elements of resources that affect their performance since the management of resources is important to ensure the effectiveness of social enterprise. Thus, this study aims to examine the role of intellectual capital, in terms of human capital, structural capital and relational capital on the effectiveness of social enterprise which is represented by the financial viability. Information on the financial viability and intellectual capital were obtained from the content analysis of the annual reports of 210 social enterprises registered under the Registry of Societies (ROS) in Malaysia for the financial period 2010. The results from the statistical analysis revealed that on average, most of the social enterprises in Malaysia would be able to financially sustain in the future. Based on the multivariate analysis, the results highlighted that human capital has a significant positive influence on the financial viability of social enterprise while structural capital and relational capital do not have significant positive relationship with the financial viability of social enterprise. Overall, the findings concluded that human capital was the most influential factor in enabling the effectiveness of social enterprise.
Government-Linked Investment Companies and Real Earnings Management: Malaysian Evidence
Authors: Rahman Rahayu Abdul , Rahman Asheq , Ghani Erlane K , Hj Omar Normah
Published: May 2019

This study examines the association between government-linked investment companies’ (GLICs’) shareholdings and real earnings management activities in Malaysia. Consistent with prior research, this study uses three proxies to measure real earnings management; abnormal cash flow from operations (RCFO), abnormal production costs (RPC), and abnormal discretionary expenses (RDE). This study segregates GLICs’ shareholdings into two categories; Federal Government Pension Investment Funds (FGPIF) and other GLICs (OFGLIC). Using a sample of 213 firm-year observations of Malaysian government-linked companies from 2010 to 2015, this study finds that FGPIF is a more effective monitoring mechanism than OFGLIC in limiting real earnings management. The findings also show that there is a significant and negative relationship between Employee Provident Fund (EPF), Khazanah Nasional Berhad (Khazanah), Permodalan Nasional Berhad (PNB) and RCFO and RPC. The evidence suggests that these three are the most effective government institutional investors in promoting corporate governance, which in turn limit real earning management activities in Malaysia. In general, the findings support the incentive alignment hypothesis, which argues that companies with government intervention are normally better governed.

Morosidade processual e a responsabilidade civil do Estado
Authors: Bontempi Alessandro , Marquesi Roberto Wagner
Published: May 2019

Com a promulgação da Emenda Constitucional nº 45/2004 foi incluído na Constituição Federal, no rol dos direitos fundamentais, a razoável duração do processo cujo objetivo é alcançar celeridade no tramite processual. Contudo, passados 13 anos da publicação da Emenda essa celeridade ainda se encontra longe do razoável. Assim, neste trabalho, dois focos foram abordados. Primeiramente, busca-se na literatura nacional e no direito comparado o conceito de razoável duração do processo. Em seguida destacamos no ordenamento nacional e no estrangeiro, as principais posições doutrinárias e jurisprudenciais a cerca da responsabilização objetiva do Estado pelo não cumprimento da razoável duração do processo, além de teses contrárias a esta.  Para demonstrar que a promessa constitucional ainda é uma distante realidade no Brasil, foram pesquisados dados que possibilitam estimar o tempo médio para baixa de um processo em primeira instância, comparando estes dados com ordenamentos estrangeiros.
Restituição do poder familiar: considerações acerca de sua possibilidade jurídica
Authors: Goulart João Pedro Minguete , Goulart Júnior Edward
Published: May 2019

O presente trabalho teve por escopo tecer considerações acerca da possibilidade da restituição do poder familiar aos genitores destituídos por sentença judicial. À luz das diretrizes consagradas no artigo 100 do Estatuto da Criança e do Adolescente (ECA), deve-se sempre analisar as demandas inerentes aos direitos de crianças e adolescentes com base nos princípios da proteção integral, do melhor interesse, bem como o da prevalência da família. Nesse sentido, a restituição do poder familiar pode surgir como uma das medidas específicas de proteção à criança e ao adolescente, uma vez que o rol do artigo 101 do ECA não é taxativo. Entende-se que, por se tratar de relação jurídica continuativa, para que seja possível o restabelecimento do poder familiar, faz-se necessário que os pais faltosos logrem êxito ao provar, em ação autônoma, que, de fato, superaram as condições que os fizeram perder o poder familiar.

Implant Engineering in the Age of Biologics
Authors: Bernthal Nicholas M. , Park Howard Y. , Zoller Stephen D. , Petrigliano Frank A.
Published: May 2019

Implants and their technological advances have been a critical component of musculoskeletal care for almost a century. Modern implants are designed to enhance bone ingrowth, promote soft-tissue healing, and prevent infection. Porous metals and short-stem fixation devices have rendered previously unreconstructable bony deficits reconstructable. Stem cells, growth factors, and novel biocompatible compounds have been designed to promote and enhance soft tissue attachment to implants. Antimicrobial modifications have been engineered onto implants to deter bacterial attachment, and innovative surface modifications and eluting technologies may be in our near future. Yet, given the enormous economic pressures in orthopaedics, marketing claims of innovation often exceed scientific accomplishment. Vigilance is thus required in distinguishing transformational discovery from unsubstantiated claims.
Human Resource Development Climate and Employee Engagement in Developing Countries
Authors: Obuobisa-Darko Theresa , Tsedzah Victoria
Published: May 2019

The purpose of the paper is to identify the specific dimensions of Human Resource Development Climate (HRDC) that significantly affect Employee Engagement (EE). It places the importance of HRDC in enhancing EE within the public sector in a developing country and finds answer to the question on the dimension of HRDC that causes employees to be engaged. The paper uses a self-designed questionnaire, made up of Rao and Abraham (1990) HRD Climate survey and Utrecht Work Engagement Scale by Schaufeli et al., (2002) to gather data from 355 respondents and analysed using multiple regression. Based on the data analysed, results showed that HRDC has a positive and significant effect on employee engagement. Additionally, it was found that employees are highly engaged in situations where their organisation exhibits the HR Mechanism dimension of HRDC. The limitation is, it did not focus on the entire public sector but focused on civil servant. It is therefore recommended that further studies could be carried out with focus on other public sector organisations to confirm or refute the findings. This study adds to the limited literature on HRDC and EE in public sector organisations in a developing country. This finding brings to bear the major dimension of HRDC that managers should focus on to improve employee engagement in a developing country where there exist a high power distance culture.
The Building Blocks of a Model Learning System for Nigerian Schools
Authors: Nwokeocha Steve
Published: May 2019

The paper was written as part of the efforts to find solution to the the falling standard of education in Nigeria. The education stakeholders and government alike strongly held the view that the standards had fallen and recently the Minister of Education called for the declaration of a state of emergency in education in order to take extraordinary measures to restore the education system to its glorious past. Against that background, the paper was written to draw attention to the fundamental issues, principles and practices which largely determine the standards of education across the world. Often, the school system in Nigeria had paid less than required attention to such fundamental issues while focusing disproportionately on matters of funding and lack of infrastructure and facilities. It is the position of the paper that though funding, infrastructure and facilities are indispensable, a proper understanding of the fundamentals of the learning system and their proper management can empower schools to record high academic achievements irrespective of their settings and material circumstances. The paper therefore addressed themes such as learner characteristics, curriculum development, instructional resources, instructional strategy, teacher competency, learning assessment and reward system.
Semantic Mapping or Rote Memorisation: Which Strategy Is More Effective for Students’ Acquisition and Memorization of L2 Vocabulary?
Authors: Badr Haytham M. , Abu-Ayyash Emad A. S.
Published: May 2019

The present paper aimed to compare the influence of two vocabulary teaching strategies on students’ vocabulary retention—roughly used in this paper to refer to the process of acquisition and memorisation. In particular, the strategies of semantic mapping and rote memorisation were compared and contrasted within a trail of evidence-based data gathered systematically from two ESL classes in an international school in the Emirate of Sharjah in the United Arab Emirates (UAE). The participants of the study were 30 male students who were in grade 12, the last stage of high school in the UAE educational system. The participants were randomly divided into two groups: a control group and an experimental group. In order to measure the impact of the two strategies under investigation on the students’ vocabulary retention, the two groups sat for a pre-test and a posttest. The intervention that took place between the two tests lasted for three weeks. The results showed that the students’ retrieval of the target vocabulary words improved as a result of implementing both strategies, but that the improvement which resulted from the use of semantic mapping overrode that which ensued from rote memorisation.
Enhancing Students’ Accuracy in Tests and Understanding of the Main Ideas of Reading Materials by Retrieval Cues in the Textbook
Authors: Zhang Hanmu
Published: May 2019

Since understanding reading assignments is important to succeeding in school, improving the way that text is arranged in books would be an efficient way to help students better understand the material and perform well on tests. In this study, we asked students to read two original and two rearranged historical passages, in which rephrased questions from the test of the passage were embedded in the reading. Those restated questions were embedded into the corresponding sections in the text where the answers for the questions were located. After the reading, they were tested on their understanding of the material with multiple choice questions. All participants took an identical test. According to the results, both groups’ accuracy was higher for the questions of the two rearranged passages in each group. In other words, the textbook makers should consider putting retrieval cues for the test into the textbook in order to make the textbooks more readable. Thus, the students’ retrieval of the concept and their performance on the test will be enhanced.
Extrinsic Factors Influencing Internal Auditors’ Effectiveness in Jordanian Public Sector
Authors: Alqudah Hamza Mohammad , Amran Noor Afza , Hassan Haslinda
Published: May 2019

This study focuses on the extrinsic factors, namely, top management support, complexity, independence, and internal audit department’s size that are out of internal auditors' control affecting their effectiveness in the Jordanian public sector. The current study also tries to improve understanding of the extrinsic factors affecting internal auditors’ ability to achieve the assigned goals in order to highlight internal auditors’ effectiveness. Resource-based and agency theories were used in developing the research model. Two sets of questionnaires were distributed among the financial managers and internal audit managers. The results reveal that top management support, independence, and the size of internal audit department play a significant and positive role on the effectiveness of internal auditors, whereas complexity of the task has been found to make a negative impact on the level of their performance. Given the significance of the public sector within the Jordanian economy, the findings are valuable for the internal audit function, regulators, and decision-makers in proposing new legislation and regulations of an internal audit function. Future studies may look into other factors that may restrict internal audit performance, such as organizational culture and pay satisfaction.

Authors: Radhakrishnamacharya G. , Alemayehu Habtu
Published: May 2019

The paper presents an analytical solution for dispersion of a solute in the peristaltic motion of a couple stress fluid through a porous medium in the presence of both homogeneous and heterogeneous chemical reactions. The average effective dispersion coefficient has been found using Taylor's limiting condition and long wavelength approximation. The effects of various relevant parameters on the average coefficient of dispersion have been studied. The average effective dispersion coefficient increases with permeability parameter but decreases with homogeneous chemical reaction rate parameter, couple stress parameter and heterogeneous reaction rate parameter.

Published: May 2019

Esta pesquisa teve como objetivo comparar as Diretrizes Curriculares Nacionais de Relações Públicas de Brasil, Argentina e Uruguai, refletindo sobre a formação no ensino superior. A metodologia conta com pesquisa bibliográfica e amparo documental. O ensino superior representa a preparação do profissional para o mundo do trabalho e neste artigo, compara-se a realidade brasileira com a dos países vizinhos no que tange o ensino de Relações Públicas no âmbito digital. Os resultados mostraram que, apenas no Brasil, há diretrizes curriculares especificadas em âmbito nacional, criadas em 2013. A respeito da carga horária, há diferença significativa entre os países estudados. E em relação ao presente cenário, que insere a profissão de Relações Públicas na cultura digital, percebemos que tal mudança é discutida de forma incipiente pela documentação oficial brasileira. Ademais, outro ponto observado é que, na Argentina e no Uruguai, os cursos de Relações Públicas têm autonomia para criar seus conteúdos.
A criança e o seu mundo: considerações acerca da educação natural nos dois primeiros livros do Emílio de Rousseau
Authors: Santa Fernando Dala
Published: May 2019

No presente artigo objetivamos abordar alguns aspectos da educação natural pensada para a infância, expostos nos Livros I e II da obra Emílio ou da Educação, de Jean-Jacques Rousseau. O conceito de educação natural permite perceber a vinculação de Rousseau ao movimento iluminista, ao mesmo tempo em que revela o modo como argumenta enquanto crítico da razão. Na primeira infância a educação natural estaria fortemente ligada à tensão entre as necessidades infantis e a intervenção adulta, cujo equilíbrio iria permitir que a criança pudesse se desenvolver em consonância com a natureza. A segunda infância, por seu turno, seria permeada por uma educação de cunho sensível, em meio a jogos e brincadeiras, favorecendo a robustez física e o refinamento dos sentidos. A educação natural estaria fundamentada, nessa perspectiva, no respeito ao mundo infantil e na consequente compreensão da criança como ser completo em sua condição especial de desenvolvimento, o que a insere em um plano pedagógico cujo mote seria a formação do homem em sentido amplo.
Internacionalização da Educação Superior: lugar, sujeito e pesquisa como categorias substantivas de análise
Authors: Oliveira Marlize Rubin , Wielewicki Hamilton De Godoy , Pezarico Giovanna
Published: May 2019

A internacionalização é uma questão de interesse crescente no contexto da Educação Superior (ES), principalmente pelos impactos da globalização dentro das instituições ao longo das últimas décadas. Este artigo busca aprofundar a análise de conceitos, políticas e ações orientadoras da internacionalização da ES, a partir de três instituições norte-americanas - Massachusetts Institute of Technology, Harvard University e Columbia University. O caminho metodológico foi percorrido a partir da abordagem qualitativa com entrevistas semiestruturadas, observações e análise documental, a partir de duas questões de investigação:1) Que concepções de internacionalização de ES estão presentes nas instituições? e 2) Que políticas e ações de internacionalização estão presentes nas instituições? Três categorias substantivas foram identificadas: Sujeito, Lugar e Pesquisa. Essas, por sua vez, expressam conceitos que sustentam políticas e ações de internacionalização. Os Sujeitos, em vez de indivíduos desprovidos de sua identidade, foram identificados como o ponto de partida e a força motriz dos processos de internacionalização. Os Lugares são espaços inerentemente repletos de contradições e possibilidades, reunindo Sujeitos que podem contar com apoio e meios para construir pontes para atuar dentro de zonas de fronteira, em esforços interdisciplinares de Pesquisa para abordar questões complexas que afetam a humanidade.

Fenomenologia do corpo em Michel Henry: uma leitura a partir da imanência subjetiva
Authors: Grzibowski Silvestre Dallek
Published: May 2019

O presente estudo visa apresentar o tema do corpo em Michel Henry mais especificamente, o corpo subjetivo a partir da imanência absoluta. As teorias clássicas e fenomenológicas investigaram a questão do corpo e deram suas contribuições, no entanto, foram constituídas a partir de uma relação transcendental. Para desenvolver o argumento do corpo subjetivo é fundamental compreender a noção de imanência, que será apresentada no primeiro momento da pesquisa. Posteriormente, será trabalhada a temática sobre o corpo subjetivo e por último, realizada uma contraposição com corpo transcendental. Assim, este ensaio busca sustentar a tese de que na fenomenologia de Henry existirá o corpo subjetivo desde que esse possa ser constituído a partir da imanência absoluta.
Corpo e liberdade: possibilidade, condição, ambiguidade
Authors: Marques Rafaela Ferreira
Published: May 2019

A questão da corporeidade enquanto presença original e originária ao mundo natural é o ponto principal deste trabalho. Para tanto são mobilizadas as teorias de Maurice Merleau-Ponty e de Simone de Beauvoir. Por ser nosso “ancoradouro no mundo”, o corpo é o que possibilita nossas experiências, sejam elas políticas, existenciais, sociais ou mesmo epistemológicas. Porém, exatamente por ser o meio de inserção no mundo o corpo se mostra também um limitador da liberdade, só que esse limite só é encarado de forma negativa por um pensamento objetivo que não aceita a ambiguidade como parte da experiência encarnada. Finalmente, refletimos sobre a situação da mulher, principalmente na obra de Beauvoir, a partir desses caracteres de potencialidades e limitações trazidas tanto pela corporeidade quanto pelo convívio necessário entre os sujeitos no mundo.

Análise do potencial teórico da geração de energia a partir do biogás no aterro sanitário de Varginha/MG
Authors: Barrak Erika
Published: May 2019

As cidades brasileiras enfrentam problemas com o destino dos resíduos sólidos urbanos, pois esses ainda são despejados em grandes quantidades em lixões sem nenhum tipo de tratamento. Nos aterros sanitários, o uso do biogás na geração de energia elétrica se tornou uma maneira sustentável de se aproveitar energeticamente os resíduos sólidos, e que ainda tem como vantagem a redução nas emissões dos gases de efeito estufa. Neste contexto, este artigo tem como objetivo avaliar o possível potencial do uso do biogás para geração de energia elétrica no aterro sanitário na cidade de Varginha/MG. O aterro sanitário hipotético geraria 1,32 MW por ano ao receber uma média de 701,84ton de resíduos por dia. A análise financeira revela que o projeto é viável, mas depende das receitas geradas pela comercialização de créditos de carbono.

El papel de las instituciones públicas resulta también decisivo, puesto que deben no solo acompañar sino potenciar las iniciativas del sector privado para asegurar su competitividad global. Todo ello debe entenderse, además, en un contexto fuertemente cambiante y donde las competencias de los profesionales logísticos marcarán, sin lugar a dudas, los éxitos del mañana.

Esta tecnología, que cuenta actualmente con fuertes planes de investigación e innovación, puede reducir enormemente la complejidad actual en los procesos de fabricación con ventajas adicionales sobre las técnicas de producción convencionales, y también en las actividades logísticas existentes en cada uno de los integrantes de la cadena de suministro.
Ancho ferroviario y logística 4.0 en el Corredor Mediterráneo
Authors: Pérez Mira Domingo
Published: May 2019

El Corredor Mediterráneo se concibe como una doble vía ferroviaria de alta velocidad que discurrirá desde la frontera francesa hasta Algeciras, uniendo ciudades tan importantes como Barcelona, Valencia, Alicante, Murcia y Málaga y conectándolas a su vez con el resto de Europa. Sin embargo, para su puesta en marcha es necesario el desarrollo de tecnologías de cambio de ancho para las plataformas ferroviarias, que permitan la transición entre los diferentes anchos de vía europeos que dificultan el tránsito de mercancías por ferrocarril. A su vez, en términos empresariales, la logística 4.0 está emergiendo con fuerza, proporcionando nuevas herramientas digitales que modifican tanto las operaciones como los procesos de negocio. Se trata de una transformación completa e integral, basada en la digitalización de la información a lo largo de toda la cadena de suministro, desde las fases iniciales hasta la llegada del producto final al cliente, integrando además la logística inversa. La convergencia de la tecnología ferroviaria de ejes de ancho variable para el transporte de mercancías con la logística 4.0 en los procesos de SCM (supply chain management) permitirá incrementar la productividad y la competitividad empresarial a escala internacional.

Possibility of tuning the differentiation state of tumor associated macrophages towards tumor controlling phenotypes
Authors: Ng Wenfa
Published: May 2019

Although various immune cells could infiltrate the cellular and tissue environment surrounding a tumor, the tumor microenvironment nevertheless presents immunosuppressive conditions unfavorable for immune cells to conduct large scale attack on cancer cells. For example, T-cells that make it to the tumor microenvironment are typically non-functional in containing tumor growth. On the other hand, macrophages could infiltrate the tumor microenvironment and is an important cell type modulated by and which also modulates the tumor. Specifically, two variants of macrophages with different phenotypes are known to exhibit close interactions with tumors. Known as M1 and M2 macrophages, they present dichotomously different signals to the tumor. Specifically, M1 macrophages control tumor growth while M2 macrophages promote tumor growth. Thus, from a treatment perspective, it would be desirable to tune the phenotypes and cell differentiation program of macrophages towards the M1 subset. To do that, differential gene expression of macrophages in the M1 and M2 lineages must be understood. Such a goal could be achieved with the profiling of tumor associated macrophages from tumor biopsy samples for gene expression patterns characteristic of the two dominant macrophage lineages. Single cell RNA-sequencing conducted after flow cytometry sorting of M1 and M2 macrophages would highlight gene expression patterns associated with each lineage, and the cellular differentiation programs that prompted entry into particular macrophage subtype. Knowledge of gene expression pattern associated with each macrophage lineage is not useful for tuning their differentiation state unless specific transcription factor that trigger the regulon could be identified. To this end, transcription factors that have been upregulated in the differentiation program could be profiled from the transcriptome data, and help inform the design of vectors for targeted overexpression of specific transcription factor for modulating cellular differentiation of macrophage. Given their low immunogenicity, adeno-associated virus (AAV) could serve as vectors for ferrying the gene cassette containing specific transcription factors into macrophages. Delivery methods for the AAV could be via targeted local infusion of vectors to tumors or through the systemic circulation, but the latter approach would result in lower transfection efficiency. Collectively, possibility exists of tuning the differentiation state of macrophage associated with tumors for enabling tumor controlling lineage to be dominant. Such immuno-targeted therapy would harness the body’s macrophages for controlling tumor growth and represents a treatment option that may yield fewer side effects compared to conventional chemotherapy. But, identification of genes that control lineage-specific differentiation program and the delivery of gene cassette to macrophages for modulating their differentiation remain key challenges.

For accelerating the development of GaN power-switching devices, current knowledge on the origins and dynamic properties of the major intrinsic nonradiative recombination centers (NRCs) in Mg-doped GaN (GaN:Mg) are reviewed, as lightly to heavily doped p-type planar GaN segments are required but certain compensating defects including NRCs hinder their formation. The results of complementary time-resolved photoluminescence and positron annihilation spectroscopy measurements on the epitaxial and ion-implanted GaN:Mg formed on low dislocation density GaN substrates indicate the following: major intrinsic NRCs are the clusters of Ga vacancies (VGas) and N vacancies (VNs), namely VGa(VN)2 in the epitaxial GaN:Mg and (VGa)3(VN)3 in the ion-implanted GaN:Mg after appropriate thermal annealings. The minimum electron capture-cross-sections of VGa(VN)2 and (VGa)3(VN)3 are commonly the middle of 10−13 cm2 at 300 K, which is approximately four times larger than the hole capture-cross-section of the major intrinsic NRCs in n-type GaN, namely VGaVN divacancies, being 7 × 10−14 cm2.

We present the modulation performance optimization process for a depletion-type Si micro-ring modulator (MRM). Our optimization process is based on two different types of model parameters for ring resonator decay time constants derived from the coupled-mode theory. The MRM figure of merit (FOM) is defined for target data rates considering both optical modulation amplitude and the modulation frequency response based on two model parameters. The parametric optimization for modulator output eye diagrams is achieved by analyzing the FOM with MRM simulation with varying two model parameters. In addition, we demonstrate the optimized eye diagram can be achieved with our optimization process and the measurement results agree well with the simulation result.
