Authors: Kraus Peter L.
Published: February 2018

In recent years, religious participation by students of all faiths at Universities in the United Kingdom has seen a steady increase in attendance. This brief essay is a case study of worship by members of the University Community at Pusey House at the University of Oxford, which reflects the trend. On a crisp fall, November day, the twenty-third Sunday after Trinity (8th of November 2015) I had the opportunity to attend services at Pusey House, Oxford on Remembrance Sunday while on sabbatical at The University of Oxford (St. Stephen’s House).
The Ancient Chinese Views of Family Education Recorded in Pre-Qin (before 221 BC) Confucian Classics
Authors: Tong Ho-kin
Published: February 2018

The Pre-Qin family education is a long neglected but important research topic in understanding Chinese education and culture. Although Chinese traditional family education is mostly under the influence of Confucianism there is not sufficient discussion in the Pre-Qin period as there are only scattered records related to this topic in various Pre-Qin classics. In addition, most research outputs in the field are on “jiaxun” (family instruction) which normally refers to family seniors’ commandments to their juniors from a cultural perspective. However, “jiating jiaoyu” (family education) can be defined as a mutual learning process in which individuals are socialized in family settings from perspectives of education and sociology. Based on this definition, the paper aims at exploring the special roles and contributions of the early Pre-Qin Confucian classics to the development of family education in China in terms of principle, aim, pedagogy, and role expectation of family member. The result shows that the Yijing (Book of Changes) brings out the views of strict family management style, supreme status of the father and role differentiation in the Pre-Qin period. The Lunyu (Analects) emphasizes the value of learning the shi (Book of Songs) and the li (Book of Rites) while the book Mengzi proposes a couple of innovative views on the parent-child relationship, role models, mutual education, environmental influence, and moral and role expectations in family education. The practicability of impartiality in family education and effectiveness of direct instruction in education are areas that need special attention from researchers and education policy makers.
Commodity: Triggering Uncertainty and Dilemma in Delillo’s White Noise
Authors: Kamal Asif
Published: February 2018

Postmodern conditions and experiences, specifically, uncertainties and contradictions, multiple interpretations or perspectives, rejection of universal, the loss of individual in the face of plurality, precede some kind of inherent predicament and dilemma as a residue or by-product of the constant commodification of life. Don Delillo’s White Noise, as a product of the postmodern era by a postmodern thinker, incorporates these traits, and predominantly, the underlying dilemma. One of the issues of this research is to trace in this novel these postmodern contradictions and dilemmas, and subsequent bathos of consumer society, under the burden of intensified productivism. This research also aims at scrutinizing these socio-personal postmodern dilemmas in the characters of the novel and ends up analyzing some psychosomatic predicaments in their deeds and thoughts relating to the personal experiences and contexts of the readers of this novel
University Involvement with Charter Schools: Unique Opportunities for Service and Support
Authors: Hentges Dr. Julie , Thomas Dr. Doug D.
Published: February 2018

Charter schools are a controversial, but vibrant, component of the current educational landscape, now serving over 3.1 million students in approximately 6900 schools across the United States.  A unique aspect of this movement has been the establishment of alternative authorizers, and specifically universities, to approve and provide oversight to these public schools.  Campus leaders and policy makers must consider numerous variables regarding a university’s involvement with charter schools.  What are the implications of school choice on university policies and practices? Should universities be “authorizers”, granting charters to schools in direct competition with the traditional public school system? Can universities provide the required “oversight” mandated by the charter school laws, as well as providing “support” for the schools? What opportunities for partnerships and practicum experiences exist?  The article provides an overview of issues that arise with public charter schools authorized by universities.  With 18 years of experiences as a public university on the forefront of enabling charter legislation and the “sponsorship” of inner-city public charter schools, the authors provide a historical perspective of the role of universities within the school choice movement, including oversight roles and supportive programs within the unique and growing phenomenon of school choice.

A Fault Tolerant Scheme for Detecting Overflow in Residue Number Microprocessors
Authors: P. A. Agbedemnab , M. A. Agebure , S. Akobre
Published: February 2018

The decomposition of larger numbers into smaller ones termed as residues is the main operation behind the concept of Residue Number System (RNS); it possesses inherent features such as parallelism and independent digit arithmetic computations. These features of the RNS has made it desirable for applications that require intensive computations such as Digital Signal Processing (DSP), Digital Filtering and Convolutions. Overflow detection is one of the major challenges that confront the efficient implementation of RNS in general purpose computer processors. Overflow occurs in RNS when an illegitimate value is represented within legitimate range – Dynamic Range (DR) as if it is legitimate value. This misrepresentation of results, which usually arises during addition operations ultimately affects systems built on this Number System. It is therefore imperative that steps are taken not to only detect but correct the occurrence of overflow whenever it occurs. In this paper, an additive overflow detection and correction scheme for the moduli set  is presented. The scheme uses a redundant modulus to extend the DR of the moduli set. The proposed scheme is demonstrated theoretically to be an efficient scheme by comparing it to previous similar works.

Tað strandaða skipið í Svínoy í 1804 – og dømir um smáhandil og loynihandil / The stranded ship in Svínoy in 1804 – and examples of small-scale shopping and smuggling
Authors: Guttesen Rolf
Published: February 2018

Úrtak: Tann 14. februar í 1804 strandaði eitt stórt skip í Svínoy við dýrabarari last av klædnastoffi og tekstil. Nógv av hesum varð bjargað uppá land, áðrenn tað í eini ódn bleiv knúst. Skipið æt Venus frá Sundsvall í Svøríki; skipari var Sam. Dryselius. Men lítið og einki er skrivað um hesa hending, hóast sjáldan ella ongantíð er størri ella dýrari vørunøgd komin inn í landið. Hon bleiv seld á uppboði, og tað sum er skriv­að í ”Auctiónsprotokollina” gevur eina frálíka mynd av hesum, hvørjar vørur vóru í lastini, hvørjir persónar keyptu, hvat teir keyptu og hvat ið prísurin var. Meira enn 5000 lutir vórðu bjargaðir í land, og selt var tilsamans fyri meira enn 12.000 Ríkisdálar. (Til samanberingar: 1 tunna av bygg kostaði vanliga umleið 5 Rdl) Teir sum keyptu størstu nøgdir, mest embæt­is­menn, hava ikki ber keypt til egið brúk. – Grein­in skal í fyrsta lagi lýsa hendingina og hvat ið fór fram á uppboðssølunum. Harnæst verð­ur roynt at greina, hvagar ið alt hetta klædna­stoffið fór. Her verður gjørt vart við, at smá­søla innanlanda ikki var tað sama sum loyni­handil. Eitt, sum kann skjalprógvast, er at Poul P. Nolsøe ólógliga hevur útflutt eina nøgd av Manchester-stoffi til Norra. Men hildið verð­ur, at nógv av stoffinum, var selt í býti við bundn­ar troyggjur og síðan sent av landinum sum sendingsgóðs við skipunum hjá Kongaliga Handlinum.Summary: On February 14th in 1804 a ship ran aground on Svínoy with a precious cargo of cloth and other textile commodities. Large amounts of these commodities were saved before the ship in a following storm was crushed. The ship was named Venus from Sundsvall in Sweden, and the captain was Sam. Dryselius. But, remarkably, very litle is written about this event, despite the fact that it was perhaps the largest and most valuable cargo ever brought ashore. It was, after a thorough registration of every item, put up for auction, and every detail of this is writen in a minute book which gives us a detailed picture of the content of the cargo, the list of persons that were buying, and what were the prices. More than 5000 items were saved and sold for more than 12.000 Rigsdaler (In comparison, the price of 1 barrel of barley was around 5 Rdl). The local officials bought the largest amounts, but it can not have been for their own consumption alone. – The article shall in the first place clear up the event and illuminate the auctions. The next problem is to attempt to follow how and where the commodities were forwarded. It is stressed that small-scale shopping is not the same as illicit traffic. One event can be documented. The skipper Poul P. Nolsøe brought an amount og Manchester-cloth to Norway, and sold it to a merchant there. This is undoubtly an incidence of smuggling. But the assumption is put forward that most of this cloth and textile was sold in exchange for sweaters that were shipped to Denmark as ”sendingsgods” (private commodities shipped by the Royal Trade Mono­poly).

In two of them the stress distribution has caused the second element to become weakened such that the sense of the name has been rendered obscure, and unclear to the language user. This has made possible a morphological reanalysis, as we can observe in the forms Jókin and (í) Gjøkkjum. The third name, Gjókinnin, on the other hand, has preserved its original form.

Authors: Siswanto Roby , Suyoso Hernu , Hayu Gati Annisa
Published: February 2018

Pasir pantai adalah salah satu kekayaan alam yang melimpah di seluruh wilayah Indonesia. Pasir pantai yang terbentuk akibat hembusan ombak dan arus laut pada karang memiliki tekstur yang halus dan bulat sangat bagus untuk material penyusun beton. Pada penelitian ini digunakan pasir pantai pulau madura dan cangkang kerang sebagai penyusn beton. Sebagai pembanding penulis juga menggunakan pasir sungai sebagai kontrol. Pada uji material didapat berat jenis pasir pantai sebesar 2,64 gr/m3, sedangkan pada pasir sungai didapat berat jenis sebesar 2,69 kg/m3. Maka dari itu, pada penelitian ini penulis membuat dua mix design yang berbeda bergantung pada sifat-sifat material penyusun beton, tetapi mutu yang disyaratkan sama yaitu K-225. Dari dua material tersebut didapat hasil yang memuaskan, pada campuran pasir pantai didapat kuat tekan sebesar 227,41 Kg/cm3. Sedangkan pada pasir sungai di dapat kuat tekan sebesar 260,74 Kg/cm3. Penggunaan cangkang kerang menggunakan tiga variasi 3%, 5% dan 7% dari kebutuhan semen, menunjukkan hasil yang posistif pada proporsi 3% dan 5% kuat tekan beton berhasil naik menjadi 237,78 Kg/cm3 dan 231,11 Kg/cm3. Sedangkan pada 7% kuat tekan beton turun menjadi 220,00 Kg/cm3. Jadi pasir pantai bisa digunakan sebagai campuran beton, dan proporsi optimum cangkang kerang ialah 3% dari total kebutuhan semen.
Uma avaliação da Lei de Informática e seus impactos sobre os gastos empresariais em P&D nos anos 2000
Authors: Brigante Paulo Cesar
Published: February 2018

O presente artigo tem como objetivo avaliar se a Lei de Informática tem sido capaz de provocar aumentos significativos de gastos em P&D, dando origem aos chamados efeitos de adicionalidade (crowd in). A análise é feita a partir da base de microdados da Pesquisa de Inovação (Pintec-IBGE), pela qual foram construídos três painéis, sendo que cada um abrange dois períodos consecutivos. Com isso, as estimativas possibilitaram verificar os efeitos da lei para os períodos de 2003-2005, 2005-2008 e 2008-2011. Buscando contornar os problemas de viés de seleção, típicos em estimativas de avaliação de políticas de inovação, aplicou-se a metodologia de diferenças-em-diferenças (DID) com covariadas. Embora os resultados indicam não haver efeitos de crowding out, os efeitos de crowd in ocorreram em apenas um período, não sendo possível concluir pela eficácia da lei ao longo de todo o período estudado.

O catecismo das Constituições Primeiras do Arcebispado da Bahia
Authors: Casimiro Ana Palmira Bittencourt Santos , Almeida Maria Cleidiana Oliveira de , Silveira Camila Nunes Duarte
Published: February 2018

Este artigo apresenta elementos da análise do catecismo estabelecido pelas Constituições Primeiras do Arcebispado da Bahia, inserido na Colônia Portuguesa da América no início do século XVIII. A partir de uma metodologia bipartida em revisão bibliográfica dos clássicos sobre os conteúdos em pauta e na análise documental, a pesquisa teve por objetivo analisar o modelo de catecismo das Constituições Primeiras (estrutura, funcionamento, forma, conteúdo e finalidade). O estudo das Constituições Primeiras do Arcebispado da Bahia é necessidade fundamental para o conhecimento da atuação catequética da Igreja em terras brasileiras, uma vez que, até o século XIX, elas foram a grande referência canônica e pastoral da Igreja no Brasil, uma colônia escravista e submissa a um Estado absolutista europeu. No decorrer da análise ficou latente que ao criar uma forma de doutrina cristã direcionada aos habitantes da colônia, como uma breve instrução dos mistérios da fé direcionada aos negros escravos, a Igreja conciliou interesses cristãos e políticos, sendo o catecismo expedido pelas Constituições Primeiras, portanto, um documento ideologicamente elaborado.

We previously produced tannase from Aspergillus niger using solid state medium. In the present study the enzyme used cashew apple juice. The aim this research was to know effect of tannase on chemical parameters of cashew apple juice. The concentration of tannase used was 0%; 0.02%; 0.04%; 0.06%; 0.08% and 0.1% (v/v). The chemical properties of the juice produced by enzymatic method were compared with the juiced produced through high temperature treatment (100oC).  This research showed that the addition of 0.1% of tannase enzyme provide the best product according to the lower content of tannins than the content of tannins in the juice produced with high temperature treatment. The tannase treatment did not change the vitamin C content, content of protein and pH. Meanwhile, high temperature treatment decreased the content of vitamin C and protein.

This research aimed to find out I- reaction order in the mechanism of  hydrogen peroxide reaction with iodide in acid condition, to find out the form of rate law, and to show the role of H+ in reaction. The experiment for determining reaction order was carried out with isolation method using UV-Vis spectrophotometry. The order reaction was obtained from the r value approaching one, the results of its linear regression. The form of rate law was viewed from the presence or absence of oxygen gas. Meanwhile the role of H+ in reaction was determined by observing the pH value in 60 minutes.

The result of experiment shows that the mechanism of reaction has rate law in the form of fraction, in which I- could be in zero and first orders. In addition, the rate law in this experimental condition is not an addition in the absence of O2 and relatively equal kobs value in the same order. The role of H+ is observed not as catalyst, but reactant.

Graphite as one alotrof carbon is widely used as an electrode material for a good electrical conductivity properties. Charcoal as a carbon source material was found very abundant in nature. Charcoal has the potential application for electrode material in energy storage such as in a battery or supercapacitor. For this purpose, charcoal amorphous structure needs to be converted into a graphite structure so that it has better electrical conductivity property. This research aims to prepare the electrical conductor material derived from wood charcoal that could potentially be used as an electrode. Preparation was made by mixing charcoal powder with asphalt binder with a weight ratio of 3:1, 4:1, 5:1 and followed by heat treatment under an inert atmosphere at temperature of 600°C, 800°C and 1000°C. Charcoal material which was originally to be an electrical insulator has been successfully converted into an electrical conductor. The achievement of the optimum temperature to produce electrodes with the smallest electrical resistance is then applied to the manufacture of carbon electrodes by heating a mixture of charcoal and fructose binder in a weight ratio of 1:1 (w/w). The results showed electrodes with a mixture of charcoal powder and fructose with heat treatment at 1000°C has the better electrical conductivity among other variations.

Intensive and long-term rainfall in Myanmar causes floods and landslides that affect thousands of people every year. However, the rainfall observation network is still limited in number and extent, so satellite rainfall products have been shown to supplement observations over the ungauged areas. One example is the estimates from Global Precipitation Measurement (GPM) called Integrated Multi-satellite Retrievals for GPM (IMERG), which has high spatial (0.1 × 0.1 degree) and temporal (30 min) resolution. This has potential to be used for modeling streamflow, early warnings, and forecasting systems. This study investigates the utility of these GPM satellite estimates for representing the daily rainfall for 25 rain gauges over Myanmar. Statistical metrics were used to understand the characteristic performance of the GPM satellite estimates. Daily rainfall estimates from GPM show a range of 29.3% to 81.1% probability of detection (POD). The satellite estimates show a capability of detecting no-rain days between 61.4 and 93.5%. For different rainfall intensities, the satellite estimates have a 12.9 to 39.1% POD for light rain (1–10 mm/day), 11.1 to 49% POD for moderate rain (10–50 mm/day), a maximum of 36% for heavy rain (50–150 mm/day), and a maximum of 12.5% for extreme rain (=150 mm/day). However, the correlation coefficient (CC) only ranges from 0.064 to 0.581, which is considered low, and is not uniform for all the stations. The highest CC scores and POD scores tend to be located in the northern part and deltaic region extending to the southern coasts in Myanmar, indicating a dependency of the statistical metrics on rainfall magnitude. The high POD scores indicate the utility of the estimates without correction for early warning purposes, but the estimates have low reliability for rainfall intensity. The satellite estimates can be used for forecasting and modeling purposes in the region, but the estimates require bias-correction before application.

Recently, national level disaster management legislation systems have been established in Myanmar, and preparation of disaster management plans at the township level has also been encouraged. This study aims to explain these disaster management plans in Myanmar through content analysis and comparison with the Japanese Municipality Disaster Management Plan. The classification of activities by 45 categories revealed the prioritized activities in the disaster management plan for each township. Furthermore, the comparison identified differences between the disaster management plans of the two countries, of which some are explained by the difference in situations in Myanmar and Japan, but the others indicate activities missed in the township disaster management plans in Myanmar.

Myanmar has experienced many types of geologic hazards such as earthquakes and landslides and to a lesser extent, subsidence. In recent years, landslides have been a major form natural disaster in Myanmar, especially in the country’s mountainous regions, such as Chin State. In geomorphological terms, Myanmar has two mountainous regions: namely the Western Ranges and the Eastern Highlands. Steep slopes, unstable geologic conditions, and heavy monsoon rains make these regions the most landslide-prone areas in Myanmar.

The study area, Hakha City and its environs, is situated in Chin State, which occupies a part of the Western Ranges. Chin State suffers many landslide incidents each year. Human settlement has recently increased as a result of rapid population growth. Consequently, natural and man-made disasters are on the rise and affecting people more than before. The most devastating landslide on record in Myanmar occurred in July 2015 due to the impact of Cyclone Koman. After this landslide, some places of Hakha City resettled in new location. However, a detailed slope stability analysis and assessment of the new location have not yet been carried out. In addition, management procedures and systems for the relocation and resettlement process still need to be evaluated for the urban safety space. Existing research and papers focus mainly on the areas affected by the landslide rather than on the city’s new location based on geographic information system (GIS) tools. It is essential to study the potential risk of landslides in the new location properly, and identify an appropriate management system.

Geological conditions including highly weathered and crushed rocks, heavy rainfall intensity, and poor drainage systems combine slope stability. Systematic management programs and technical control methods can mitigate the number and magnitude of future disasters.
