Shear Band Morphology of Indented Region in Cu-Based Metallic Glass
Authors: Csach Kornel , Hurakova Maria , Juríková Alena , Miškuf Jozef , Ocelík Václav , de Hosson Jeff T.M.
Published: March 2017

Plastic deformation after indentation of the metallic glass Cu47Ti35Zr11Ni6Si1 at different loading conditions was examined. Discontinuities on the loading curves were observed, the magnitude of which depends on the loading rate. The presence of these discontinuities is influenced by the precise shape of the indentation tip. At lower loading rates and using a cube corner indenter tip the discontinuities on the loading curves are more pronounced. An increase of the loading rate tends to diminish instantaneous plastic deformation as appear by pop-ins. Using a Berkovich type indenter tip the plastic deformation is more steady. It is concluded that the final morphology of the pile-up area strongly depends on the geometry of the indenter tip, whereas no correlation between discontinuities in the loading part of the indentation curve and the formation of shear band patterns was observed.

Published: March 2017

The Ni-NiO skeleton seems to be a good candidate for various applications in industry such as corrosion-proof filters or components in refrigerating systems and as preforms for reactive infiltration with molten metals.The present work was focused on preparation of Ni-NiO composite with higher, controlled porosity. Sintering of pure Ni powder always leads to a substantial closed porosity in almost whole sample volume [1,2]. To eliminate this, we added Al2O3 particles with diameter of-32 +20 μm into the Ni powder (-75 +45 μm diameters) and sintered this loose powder mixture (Ni + 25 vol. % Al2O3) in air by progressive heating up to 800 °C followed by 2 hours isothermal exposure. As a control, pure Ni powder was sintered under the same conditions. Thermal oxidation of loose powder samples performed in alumina crucible indicates that the strongest oxidation occurred in the top part of sample, while the bottom part was the least oxidized. Therefore, it was necessary to run the thermal oxidation once more, but out of the crucible, to ensure the sufficient diffusion of oxygen to the whole volume of sample.
Slag Investigations from Bronze Age Copper Smelting Sites
Authors: Haubner Roland , Strobl Susanne
Published: March 2017

During the Bronze Age intensive mining and smelting activities for copper production took place in the Eastern Alps. To get information about the copper smelting process, the elemental compositions of slags are marked in equilibrium phase diagrams (e.g. FeO-CaO-SiO2) and so the melting properties can be estimated. Doing so you have to keep in mind that slags have complex compositions and phase diagrams are available for three compounds only. For the analytical measurements it has to be ensured that only molten parts of the slag are measured and not contamination of other ambient material. Spot and area measurements by SEM-EDX are useful to get realistic data. In this case a complete correlation between the image of the analyzed area, the microstructure and the chemical composition of the sample is necessary. For marking spots in the phase diagram the calculation method has to be described exactly. For our results we calculated the ratio FeO-SiO2-CaO(+MgO+Al2O3). From the morphology of the observed phases, their chemical composition and the data from the phase diagram a solidification sequence can be suggested.
We recommend this method because measurements by e.g. XRF provide rather general composition values. If the slag samples are inhomogeneous, unrealistic melting points are read from the phase diagram. Inhomogeneities can be caused by soil contaminations, which are not part of the molten slag, or by corrosion, when some phases were attacked and changed during storage in soil.

Published: March 2017

SO42-/TiO2, SO42-/Fe2O3 nanoparticles were prepared by the impregnation precipitation method. The X-ray diffraction (XRD), scanning electron microscopy (SEM), and energy disperse spectroscopy (EDS) results showed that the uniform size of SO42-/TiO2, SO42-/Fe2O3 nanoparticles with high purity, good dispersivity and particle size range from 50nm to 200nm. A comparative study between SO42-/TiO2 and SO42-/Fe2O3 nanoparticles applied in the photocatalytic experiment on unsymmetrical dimethylhydrazine (UDMH) wastewater was carried out.
Kinetics of Cavitation Bubble in Ultrasonic Degassing of Casting Aluminium Alloy
Authors: Liu Miao , Zhai Peng , Long Qiang , Wang Chun Yang , Xiao Bo Han
Published: March 2017

Severe regassing was detected by previous experiment on degassing method for aluminium-silicon alloy by injecting argon with rotation. In order to further degas, ultrasonic degassing was adopted. To describe the cavitation bubbles’ movement, traditional Rayleigh-Plesset equation was modified. Classic Rayleigh-Plesset equation is strongly restricted by the applicable condition that the centre of the bubble is fixed. In this paper, a position-related Rayleigh-Plesset equation is proposed to describe the cavitation bubble's floating movement in aluminium-silicon alloy of 750°C with the coefficient of viscosity of 0.0012. As the calculation results, a bubble stimulated by high-low-frequency vibration can float up faster with violent vibration.
Electronic Structures of Vacancy Defective Chiral (6,2) SiC Nanotubes
Authors: Li Ke Jian , Liu Hong Xia
Published: March 2017

Vacancy defects are common defects formed in the syntheses of silicon carbide nanotubes (SiCNTs) and seriously impact the electronic structures of the nanotubes. With first-principle calculations based on density functional theory (DFT), vacancy defective (6,2) SiCNTs are studied. Vacancies form a pair of fivefold and ninefold rings. Carbon vacancy introduces an occupied defect level near the top of the valence band and an unoccupied level in the conduction band. Three defect levels are found in the band gap of the SiCNT with a silicon vacancy. These results are helpful for investigations on SiCNT devices and sensors.
The Influence of Hydrostatic Pressure and Electric Field to the Remanent Polarization of PbLa(Zr,Sn,Ti)O3 Ceramic
Authors: Zhang Chong Hui , Wang An Xiang , Gao Bin
Published: March 2017

Chemical composition Pb0.97La0.02(Zr0.75Sn0.136Ti0.114)O3 (PLZST) ceramic was fabricated by conventional solid-state reaction of oxide method. The composition is close to the AFE/FE phase boundary of PLZST ceramic phase diagram. The dependence of remanent polarization of Pb (Zr,Sn,Ti)O3 ceramic poled under different electric fields on hydrostatic pressure was investigated with special hydrostatic pressure equipment. The results show that PLZST ceramic poled at different DC electric field is metastable state ferroelectric phase. The remanent polarization decreases sharply and is depolarization completely when hydrostatic pressure increases to a bound.

Published: March 2017

The novel solid NaXe nanoclusters were prepared. Measurements and calculations indicated that solid NaXe nanocluster has easily vibration- dissociated ground state and stable excited state to emit UV radiation. In the meanwhile the solid nanocluster NaXe retains fcc position within the host NaCl matrix. Therefore，the integrated ultraviolet(UV)-micro-excimer-laser-matrix can be prepared by using solid NaXe nanoclusters.

Published: March 2017

NK cells are part of the innate immune system, and are able to identify and kill hazardous cells. The discrimination between normal and hazardous cells is possible due to an array of inhibitory and activating receptors. NKG2D is one of the prominent activating receptors expressed by all human NK cells. This receptor binds stress-induced ligands, including human MICA, MICB, and UL16-binding proteins 1-6. The interaction between NKG2D and its ligands facilitates the elimination of cells under cellular stress, such as tumor transformation. However, the mechanisms regulating the expression of these ligands are still not well understood. Under normal conditions, the NKG2D ligands were shown to be posttranscriptionally regulated by cellular microRNAs and RNA-binding proteins (RBPs). Thus far, only the 3′ untranslated regions (UTRs) of MICA, MICB, and UL16-binding protein 2 were shown to be regulated by RBPs and microRNAs, usually resulting in their downregulation. In this study we investigated whether MICB expression is controlled by RBPs through its 5′UTR. We used an RNA pull-down assay followed by mass spectrometry and identified vigilin, a ubiquitously expressed multifunctional RNA-binding protein. We demonstrated that vigilin binds and negatively regulates MICB expression through its 5′UTR. Additionally, vigilin downregulation in target cells led to a significant increase in NK cell activation against said target cells. Taken together, we have discovered a novel mode of MICB regulation.

Th17 cells play a critical role in autoimmune diseases, including multiple sclerosis and its animal model, experimental autoimmune encephalomyelitis. Response gene to complement (RGC)-32 is a cell cycle regulator and a downstream target of TGF-β that mediates its profibrotic activity. In this study, we report that RGC-32 is preferentially upregulated during Th17 cell differentiation. RGC-32−/− mice have normal Th1, Th2, and regulatory T cell differentiation but show defective Th17 differentiation in vitro. The impaired Th17 differentiation is associated with defects in IFN regulatory factor 4, B cell–activating transcription factor, retinoic acid–related orphan receptor γt, and SMAD2 activation. In vivo, RGC-32−/− mice display an attenuated experimental autoimmune encephalomyelitis phenotype accompanied by decreased CNS inflammation and reduced frequency of IL-17– and GM-CSF–producing CD4+ T cells. Collectively, our results identify RGC-32 as a novel regulator of Th17 cell differentiation in vitro and in vivo and suggest that RGC-32 is a potential therapeutic target in multiple sclerosis and other Th17-mediated autoimmune diseases.

Published: March 2017

Antimicrobial stewardship is widely accepted as an efficient strategy to combat the growing threat of antimicrobial resistance. Education is one of the cornerstones of successful antimicrobial stewardship programs. There is also general agreement that antimicrobial stewardship is a team effort that must involve the whole continuum of healthcare workers. Providing adequate education for all different professionals although challenging is deemed crucial to achieve good results. This paper reviews the different strategies available to educate the multiple healthcare workers, discusses how education can improve antimicrobial stewardship programs and outlines some of the challenges faced and research gaps that need to be addressed in order to improve education in this field.

Parry-Romberg Syndrome: A Case Study of Two Patients
Authors: Saxena Shikhar
Published: March 2017

Introduction

Parry-Romberg syndrome is a rare neurocutaneous disorder, i.e., characterized by a slow and progressive atrophy of facial tissues, including muscles, bones, and skin of one or occasionally both sides of the face. Atrophy may be preceded by cutaneous discoloration of the affected skin, such as hyperpigmentation or depigmentation.

Observation

A 30-year-old female patient came with a chief complaint of progressive deformity of left-side face since 7 to 8 years. Progressive atrophy on left half face was noticed first at the age of 23 years as an area of hyperpigmentation on left malar region, which progressed with atrophy of the underlying fat and subcutaneous tissue resulting in disfigurement. Head and neck examination confirmed the asymmetry with flattening and hyperpigmentation on left side of face. There was an evident loss of underlying fat, muscle, and subcutaneous tissue giving a sunken appearance. Computed tomography scan revealed generalized atrophy of the soft tissue of the left hemi face resulting in asymmetry on the left side with deviated nasal septum. Another female patient of 35 years old came to the Department of Otorhinolaryngology with marked facial asymmetry on right side.

Conclusion

Two cases of PRS from different families are discussed. A 30-year-old female who presented with chief complaints of left side hemifacial atrophy and blackish pigmentation of overlying skin whose clinical features were consistent with PRS and a 35-year-old female with right-sided facial hemifacial atrophy.

A Tribe Called Quest's People’s Instinctive Travels and the Paths of Rhythm
Authors: Taylor Shawn
Published: March 2017

One of the finest hip-hop albums ever made, A Tribe Called Quest’s debut record (featuring stone-cold classics like “Can I Kick It?” and “Bonita Applebum”) took the idea of the boasting hip-hop male and turned it on its head. For many listeners, when this non-traditional, surprisingly feminine album was released, it was like hearing an entirely new form of music.

In this book, Shawn Taylor explores the creation of the album as well as the impact it had on him at the time - a 17-year-old high-school geek who was equally into hip-hop, punk, new wave, skateboarding, and Dungeons & Dragons: all of a sudden, with this one album, the world made more sense. He has spent many years investigating this album, from the packaging to the song placement to each and every sample - Shawn Taylor knows this record like he knows his tattoos, and he’s finally been able to write a fascinating and highly entertaining book about it.
AC/DC’s Highway to Hell
Authors: Bonomo Joe
Published: March 2017

Released in 1979, AC/DC’s Highway To Hell was the infamous last album recorded with singer Bon Scott, who died of alcohol poisoning in London in February of 1980. Officially chalked up to “Death by Misadventure,” Scott’s demise has forever secured the album’s reputation as a partying primer and a bible for lethal behavior, branding the album with the fun chaos of alcoholic excess and its flip side, early death. The best songs on Highway To Hell achieve Sonic Platonism, translating rock & roll’s transcendent ideals in stomping, dual-guitar and eighth-note bass riffing, a Paleolithic drum bed, and insanely, recklessly odd but fun vocals.

Joe Bonomo strikes a three-chord essay on the power of adolescence, the durability of rock & roll fandom, and the transformative properties of memory. Why does Highway To Hell matter to anyone beyond non-ironic teenagers? Blending interviews, analysis, and memoir with a fan’s perspective, Highway To Hell dramatizes and celebrates a timeless album that one critic said makes “disaster sound like the best fun in the world.”
Aphex Twin's Selected Ambient Works Volume II
Authors: Weidenbaum Marc
Published: March 2017

Extravagantly opaque, willfully vaporous - Aphex Twin’s Selected Ambient Works Volume II, released by the estimable British label Warp Records in 1994, rejuvenated ambient music for the Internet Age that was just dawning. In the United States, it was Richard D. James’s first full length on Sire Records (home to Madonna and Depeche Mode) under the moniker Aphex Twin; Sire helped usher him in as a major force in music, electronic or otherwise.

Faithful to Brian Eno’s definition of ambient music, Selected Ambient Works Volume II was intentionally functional: it furnished chill out rooms, the sanctuaries amid intense raves. Choreographers and film directors began to employ it to their own ends, and in the intervening decades this background music came to the fore, adapted by classical composers who reverse-engineered its fragile textures for performance on acoustic instruments. Simultaneously, “ambient” has moved from esoteric sound art to central tenet of online culture. This book contends that despite a reputation for being beatless, the album exudes percussive curiosity, providing a sonic metaphor for our technologically mediated era of countless synchronized nanosecond metronomes.
Black Sabbath's Master of Reality
Authors: Darnielle John
Published: March 2017

Black Sabbath’s Master of Reality has maintained remarkable historical status over several generations; it’s a touchstone for the directionless, and common coin for young men and women who’ve felt excluded from the broader cultural economy. John Darnielle hears it through the ears of Roger Painter, a young adult locked in a southern California adolescent psychiatric center in 1985; deprived of his Walkman and hungry for comfort, he explains Black Sabbath as one might describe air to a fish, or love to an android, hoping to convince his captors to give him back his tapes.
Captain Beefheart's Trout Mask Replica
Authors: Courrier Kevin
Published: March 2017

In the spring of 1969, the inauspicious release of Captain Beefheart and the Magic Band’s Trout Mask Replica, a double-album featuring 28 stream-of-consciousness songs filled with abstract rhythms and guttural bellows, dramatically altered the pop landscape.

Yet even if the album did cast its radical vision over the future of music, much of the record’s artistic strength is actually drawn from the past. This book examines how Beefheart’s incomparable opus, an album that divided (rather than) united a pop audience, is informed by a variety of diverse sources. Trout Mask Replica is a hybrid of poetic declarations inspired by both Walt Whitman and the beat poets, the field hollers of the Delta Blues, the urban blues of Howlin’ Wolf, the gospel blues of Blind Willie Johnson, and the free jazz of Ornette Coleman. This book illustrates how Trout Mask Replica was not so much an arcane specimen of the avant-garde, but rather a defiantly original declaration of the American imagination.
Dinosaur Jr.'s You’re Living All Over Me
Authors: Attfield Nick
Published: March 2017

Dinosaur Jr, the stereotypical slackers. Mascis, Barlow, Murph (just Murph): three early-twentysomethings still overburdened by a torpid adolescence and a disastrous dress sense. With battered guitar, bass, and kit, they carry around a catalogue of songs that betrays identities half-formed at best, schizoid at worst.

But listen. 1987, a new album, a snapshot of a moment when a furious musical intensity swung upwards and pushed their lyrics and Mascis’s vocal whine far into the margins. Searing riffs, mountainous solos, and the tightest of fills – underpinned by stream-of-consciousness structures and a palette of crazed effects – steal the show. These three build a one-off sound that stirred up the hardening alternative mainstream and drove it to distraction. You’re Living All Over Me: supposedly Mascis’s indictment of what it was like to tour in a van with these other two misfits, but also testimony to the obsession – an itch, a disease – that the band’s disengagement from their world had produced. This record cares so little it cares a lot.
DJ Shadow's Endtroducing…
Authors: Wilder Eliot
Published: March 2017

What resonated about Endtroducing when it was released in 1996, and what makes it still resonate today, is the way in which it loosens itself from the mooring of the known and sails off into an uncharted territory that seems to exist both in and out of time. Josh Davis is not only a master sampler and turntablist supreme, he is also a serious archeologist with a world-thirsty passion (what Cut Chemist refers to as Josh’s “spidey sense”) for seeking out, uncovering and then ripping apart the discarded graces of some other generation - that “pile of broken dreams” - and weaving them back together into a tapestry of chronic bleakness and beauty.

Over the course of several long conversations with Josh Davis (DJ Shadow), we learn about his early years in California, the friends and mentors who helped him along the way, his relationship with Mo’Wax and James Lavelle, and the genesis and creation of his widely acknowledged masterpiece, Endtroducing.

Flying Burrito Brothers' The Gilded Palace of Sin
Authors: Proehl Bob
Published: March 2017

In 1968, the Flying Burrito Brothers released The Gilded Palace of Sin on A&M Records,selling a disappointing 400,000 copies. Almost forty years later, front man Gram Parsons, is still spoken of with almost messianic reverence. Patron saint of alt-country, emblazoned with a shining cross, dead at 26. Overshadowed by Parsons, this album remains an anomaly in the country rock genre, a map in miniature of a moment in music, and warrants discussion as more than part of the Gram Parsons legacy.
Guided By Voices' Bee Thousand
Authors: Woodworth Marc
Published: March 2017

Marc Woodworth’s book covers the album’s long and unorthodox period of writing, recording, sequencing, and editing. It includes interviews with members of the band, manager Pete Jamison, web-master and GBV historian Rich Turiel and Robert Griffin of Scat Records. At least sixty-five songs were recorded and considered for the album and five distinct concepts were rejected before the band hit upon the records final form. One late version, very nearly released, contained only a few of Bee Thousand’s definitive songs.

The rest were left out and nearly ended up in the boxes of cassette out-takes cluttering up Robert Pollard’s basement. The story of Guided By Voices transformation from an occasional and revolving group of complete unknowns to indie-rock heroes is very much part of the story behind the making of Bee Thousand.

In addition to providing a central account of how the record was made, Woodworth devotes a substantial chapter to the album’s lyrics. Robert Pollard’s lyrics are described by critics, when they’re described at all, as a brand of tossed-off surrealism, as if his verbal sensibility is somehow incidental to the songs themselves. Nothing could be further from the truth. Woodworth offers a sustained discussion of Pollard’s work as a writer of often sublime, beautiful, and very human lyrics.

The third key section of the book covers aesthetics. Woodworth considers the great appeal of the do-it-yourself nature of Bee Thousand and reflects on the larger importance of the strain of alternative rock for which this record is a touchstone.
Source attribution of black carbon and its direct radiative forcing in China
Authors: Yang Yang , Wang Hailong , Smith Steven J. , Ma Po-Lun , Rasch Philip J.
Published: March 2017

Abstract. The source attributions for mass concentration, haze formation, transport and direct radiative forcing of black carbon (BC) in various regions of China are quantified in this study using the Community Earth System Model (CESM) with a source-tagging technique. Anthropogenic emissions are from the Community Emissions Data System that is newly developed for the Coupled Model Intercomparison Project Phase 6 (CMIP6). Over north China where the air quality is often poor, about 90 % of near-surface BC concentration is contributed by local emissions. Overall, 35 % of BC concentration over south China in winter can be attributed to emissions from north China, and 19 % comes from sources outside China in spring. For other regions in China, BC is largely contributed from nonlocal sources. We further investigated potential factors that contribute to the poor air quality in China. During polluted days, a net inflow of BC transported from nonlocal source regions associated with anomalous winds plays an important role in increasing local BC concentrations. BC-containing particles emitted from East Asia can also be transported across the Pacific. Our model results show that emissions from inside and outside China are equally important for the BC outflow from East Asia, while emissions from China account for 8 % of BC concentration and 29 % in column burden in the western United States in spring. Radiative forcing estimates show that 65 % of the annual mean BC direct radiative forcing (2.2 W m−2) in China results from local emissions, and the remaining 35 % is contributed by emissions outside of China. Efficiency analysis shows that a reduction in BC emissions over eastern China could have a greater benefit for the regional air quality in China, especially in the winter haze season.
Characterizing the spatial variations and correlations of large rainstorms for landslide study
Authors: Gao Liang , Zhang Limin , Lu Mengqian
Published: March 2017

Abstract. Rainfall is the primary trigger of landslides in Hong Kong; hence rainstorm spatial distribution is an important piece of information in landslide hazard analysis. The primary objective of this paper is to quantify spatial correlation characteristics of three landslide-triggering large storms in Hong Kong. The spatial maximum rolling rainfall is represented by a rotated ellipsoid trend surface and a random field of residuals. The maximum rolling 4-h, 12-h, 24-h and 36-h rainfall amounts of these storms are assessed via surface trend fitting, and the spatial correlation of the detrended residuals is determined through studying the scales of fluctuation along eight directions. The principal directions of the surface trend are between 19° and 43°, and the major and minor axis lengths are 83–386 km and 55–79 km, respectively. The scales of fluctuation of the residuals are found between 5 km and 30 km. The spatial distribution parameters for the three large rainstorms are found to be similar to those for four ordinary rainfall events. The proposed rainfall spatial distribution model and parameters help define the impact area, rainfall intensity and local topographic effects for landslide hazard evaluation in the future.
Precise age for the Permian–Triassic boundary in South China from high-precision U-Pb geochronology and Bayesian age–depth modeling
Authors: Baresel Björn , Bucher Hugo , Brosse Morgane , Cordey Fabrice , Guodun Kuang , Schaltegger Urs
Published: March 2017

Abstract. This study is based on zircon U-Pb ages of 12 volcanic ash layers and volcanogenic sandstones from two deep water sections with conformable and continuous formational Permian–Triassic boundaries (PTBs) in the Nanpanjiang Basin (South China). Our dates of single, thermally annealed and chemically abraded zircons bracket the PTB in Dongpan and Penglaitan and provide the basis for a first proof-of-concept study utilizing a Bayesian chronology model comparing the three sections of Dongpan, Penglaitan and the Global Stratotype Section and Point (GSSP) at Meishan. Our Bayesian modeling demonstrates that the formational boundaries in Dongpan (251.939 ± 0.030 Ma), Penglaitan (251.984 ± 0.031 Ma) and Meishan (251.956 ± 0.035 Ma) are synchronous within analytical uncertainty of  ∼  40 ka. It also provides quantitative evidence that the ages of the paleontologically defined boundaries, based on conodont unitary association zones in Meishan and on macrofaunas in Dongpan, are identical and coincide with the age of the formational boundaries. The age model also confirms the extreme condensation around the PTB in Meishan, which distorts the projection of any stratigraphic points or intervals onto other more expanded sections by means of Bayesian age–depth models. Dongpan and Penglaitan possess significantly higher sediment accumulation rates and thus offer a greater potential for high-resolution studies of environmental proxies and correlations around the PTB than Meishan. This study highlights the power of high-resolution radio-isotopic ages that allow a robust intercalibration of patterns of biotic changes and fluctuating environmental proxies and will help recognizing their global, regional or local significance.
A probabilistic approach to quantifying soil physical properties via time-integrated energy and mass input
Authors: Shepard Christopher , Schaap Marcel G. , Pelletier Jon D. , Rasmussen Craig
Published: March 2017

Abstract. Soils form as the result of a complex suite of biogeochemical and physical processes; however, effective modeling of soil property change and variability is still limited and does not yield widely applicable results. We suggest that predicting a distribution of probable values based upon the soil-forming state factors is more effective and applicable than predicting discrete values. Here we present a probabilistic approach for quantifying soil property variability through integrating energy and mass inputs over time. We analyzed changes in the distributions of soil texture and solum thickness as a function of increasing time and pedogenic energy (effective energy and mass transfer, EEMT) using soil chronosequence data compiled from the literature. Bivariate normal probability distributions of soil properties were parameterized using the chronosequence data; from the bivariate distributions, conditional univariate distributions based on the age and flux of matter and energy into the soil were calculated and probable ranges of each soil property determined. We tested the ability of this approach to predict the soil properties of the original soil chronosequence database and soil properties in complex terrain at several Critical Zone Observatories in the US. The presented probabilistic framework has the potential to greatly inform our understanding of soil evolution over geologic timescales. Considering soils probabilistically captures soil variability across multiple scales and explicitly quantifies uncertainty in soil property change with time.

An Exploration of the Time-varying Beta of the International Capital Asset Pricing Model: The Case of the Japanese and the Other Asia-Pacific Stock Markets
Authors: Tsuji Chikashi
Published: March 2017

This study clarifies the state of dynamic evolution of the international CAPM betas for Asia Pacific (excluding Japan) and Japanese stock returns: first, both for Asia Pacific and Japanese stock markets, the time-invariant international CAPM beta values are not high. Second, over the period from July 2, 1990 to May 30, 2016, for Asia Pacific stock markets, the time-varying international CAPM betas gradually increase; while for the Japanese market, the time-varying international CAPM betas gradually decrease. We also find that the international time-varying CAPM betas for Japan are recently lower than those for Asia Pacific markets, thus, in the global equity investments, Japanese equities are more useful to obtain the diversification effects than the other Asia Pacific equities.

Published: March 2017

The U.S. Department of Defense (DoD) has recently revised the defense acquisition system to address suspected root causes of unwanted acquisition outcomes. One of the major changes in the revised acquisition system is an increased emphasis on systems engineering trade-offs made between capability requirements and lifecycle costs early in the acquisition process (Cilli, Parnell, Cloutier, & Zigh, 2015). Given that systems engineering trade-off analyses will play a pivotal role in future defense acquisition efforts, this paper takes an in-depth look at the state of systems engineering trade-off analysis capability through a review of relevant literature and a survey of systems engineering professionals and military operations research professionals involved in defense acquisition. The survey was developed to measure the perceived level of difficulty associated with compliance to the revised defense acquisition system mandate for early systems engineering trade-off analyses and to measure perceived likelihood and impact of potential pitfalls within systems engineering trade-off studies. The survey instrument was designed using Survey Monkey and was deployed through a link posted on several groups within LinkedIn, a professional social media site, and was also sent directly via email to those with known experience in this research area. Although increased systems engineering activity early in the life cycle is a compelling change for DoD, the findings of the literature review and the survey of practitioners both indicate that there is much to be done in order to position the systems engineering community for success so that the improved defense acquisition outcomes as envisioned by the architects of 2015 DoDI 5000.02 can be realized.

Published: March 2017

The present study explored the impact of corporate governance on the financial performance of selected Jordanian banks. The study is based on secondary data collected from Annual Reports of Companies, research papers, articles and various websites. The sample of the study consists of five banks of Jordan. Multiple regression has been used as the statistical tool to measure the impact of corporate governance on the financial performance of banks under study. Corporate governance score is taken as independent variable while ROA is used as dependent proxy variable of financial performance. The findings of the current research highlighted that corporate governance score has a positive significant impact on the financial performance of Capital Bank of Jordan, Arab Bank, and Bank Al-Etihad. However, significant impact does not found on the financial performance of Jordan Islamic Bank and Jordan Dubai Islamic Bank.

Authors: Muntaka Abdul Samed , Haruna Ashraf , Kofi Mensah Henry
Published: March 2017

This study explores the significance of integration and flexibility as critical determinants of business performance by examining the connection amongst supply chain integration and flexibility on the one hand and business performance on the other.  Using mainly a cross-sectional approach, structured questionnaire was used to collect responses from two hundred and fifty-five employees drawn registered companies in the Kumasi Metropolis and analyzed with the help of Pearson’s correlation and structural equation modeling (SEM). Three elements of supply chain integration (company integration with suppliers, cross functional integration within a company and company integration with customers) and three elements of supply chain flexibility (adaptability, alignment and agility) were subjected to analysis. The results indicate that supply chain integration and supply chain flexibility exhibit significant correlation with firm performance. Supply chain integration and supply chain flexibility have high correlation with ‘financial performance’ followed by ‘logistic performance’ and then ‘operational performance’. Also, the results demonstrate that four supply chain integration surrogates; ‘production data integration’, ‘going after customers for feedback’, ‘periodic connection with customers’ and ‘real time search of inventory’ and two supply chain flexibility proxies specifically ‘technology’ and ‘supply network strategies’ are crucial as they exhibit the most noteworthy influence on firm performance. Results of this study offer remarkable demonstrations of the effects of integration and flexibility in enhancing performance of businesses and greater attention must be paid to those proxies of supply chain integration and flexibility that exhibited the most significant impact on firm’s performance.

Published: March 2017

A novel analytical reagent, 4-(2-hydroxyphenylethamino)benzene-1,3-diol was synthesized for determination of nickel(II) in biological samples and plant materials by extractive differential pulse polarography. The analysis of nickel(II) was carried out by extracting the nickel(II)-(4-(2-hydroxyphenylethamino)benzene-1,3-diol) complex from chloroform prior to injecting into the instrument. The electrochemical behavior of nickel(II) complex was studied under optimum parameters like effect of pH, pulse amplitude, scan rate and choice of solvent. The calibration curve was constructed in the concentration range of 0.05-42 µg mL-1 at pH 4.0 (acetate buffer) with a correlation coefficient of 0.992, respectively. Interference of diverse ions was also investigated during the analysis of nickel(II) to optimize the conditions. The accuracy and validity of the proposed method were checked by the analysis of Certified Reference Materials which is distributed by the National Institute of Standard Technology
Chronic rhinosinusitis in children
Authors: Zielnik-Jurkiewicz Beata
Published: March 2017

CRS symptoms in children can be mild and uncharacteristic. The disease is multifactorial, and therefore requires a multifaceted, multidisciplinary approach. Treatment of CRS in children is difficult, infections often recur, and treatment methods are often ineffective. In children, surgery is performed infrequently, only when other therapies have failed. The first stage of surgery is adenoidectomy. Functional endoscopic surgery of the paranasal sinuses may be considered if no improvement of the patient after exhausting all possibilities of conservative treatment.
“Gifts and Calling”: The Fruits of Coming to Know Living Jews
Authors: Langer Ruth
Published: March 2017

In the process of implementing Nostra Aetate’s teachings about Jews and Judaism, the Catholic Church came to realize that its leaders and laity needed to come to know Jews. This process has deeply transformed Catholic-Jewish relations, as is evident in the Vatican’s Commission for Religious Relations with the Jews newest document “‘The Gifts and Calling of God are Irrevocable’ (Rom 11:29): A Reflection on Theological Questions Pertaining to Catholic-Jewish Relations on the Occasion of the 50th Anniversary of Nostra Aetate (No. 4).”  This essay will first trace the emergence of this living engagement and then turn to an analysis of how it has shaped this new document.
The Uniqueness of the Christian-Jewish Dialogue: A Yes and a No
Authors: Pawlikowski John
Published: March 2017

Many +people connected with the Christian-Jewish dialogue as well as some ecclesial documents, including THE GIFTS AND THE CALLING OF GOD, have declared the church's relationship with the Jewish People totally unique.  There is certainly an important dimension of this claim. Christianity has a theological and historical link with Judaism that is sui generis.  The church accepts the Jewish Scriptures as revelatory and since Vatican II has proclaimed a special bonding with the Jewish People, a bonding it does not enjoy with any other world religion. But there is a danger that the uniqueness is sometimes overemphasized including in THE GIFTS AND THE CALLING.  Such overemphasis has the potential to marginalize the Christian-Jewish dialogue as exclusively a North Atlantic issue. There is need to show how the documents generated by the Christian-Jewish dialogue have relevance for global Christianity and for the dialogue with other world religions.
Christ, Torah, and the Faithfulness of God: The Concept of Supersessionism in “The Gifts and the Calling”
Authors: Tapie Matthew
Published: March 2017

This article analyzes usage of the term “supersessionism,” in the December 2015 document authored by the Pontifical Commission for Religious Relations with the Jews, and entitled, “The Gifts and the Calling of God are Irrevocable: A Reflection on Theological Questions Pertaining to Catholic-Jewish Relations on the Occasion of the 50th Anniversary of Nostra Aetate” (No.4). After setting the document in the context of postconcilar Catholic reflection on Jews and Judaism, the article argues that while “Gifts and the Calling” provides important guidance for theological reflection, the document does not identify supersessionism with necessary precision. Drawing upon the thought of the French-Jewish historian Jules Isaac, and the Methodist theologian R. Kendall Soulen, the article demonstrates how their critical remarks about a particular Christian teaching regarding Christ’s fulfillment of Jewish law greatly clarifies the language of supersessionism for the Catholic-Jewish dialogue.

ESTRUTURA DO ATENDIMENTO À SAÚDE DA CRIANÇA NO BRASIL
Authors: Freitas Corina Bontempo Duca de
Published: March 2017

O atendimento à saúde da criança no Brasil se caracteriza pelo enfoque no atendimento por intercorrências, centrado no médico. Há pouca participação de outros profissionais,principalmente de enfermeiros. A força de trabalho está polarizada entre médicos e atendentes de baixo nível de escolaridade. Os recursos humanos se concentram nas regiõesmais desenvolvidas, em prejuízo das populações rurais e periféricas que ainda enfrentam dificuldade de acesso. É pequena a of erta de consultórios de pediatria pelo setor privado lucrativo, que investe mais no atendimento hospitalar. O grande prestador de assistência pediátrica são as entidades filantrópicas, sem fins lucrativos. A oferta total de consultaspara crianças de O a 14 anos está em média em 1,3 consultas/criança/ano, sendo muito insuficiente para acompanhamento da saúde.O atendimento domiciliar por agentes de saúde tem sido uma via alternativa para melhoria da cobertura das ações de promoção e prevenção.Considerando a capacidade instalada total evidencia-se uma baixa produtividade dos consultórios públicos de pediatria, que poderia ser até triplicada se houvesse adequação derecursos humanos.
