Published: April 2017

Keberadaan Bus Rapid Transit (BRT) di Kota Semarang diharapkan dapat menjadi salah satu solusi akan permasalahan kemacetan, adanya BRT ini terutama pada trayek perjalanan koridor II, ternyata mendapatkan tanggapan positif dari masyarakat pengguna, terbukti dari meningkatnya permintaan yang terjadi dari tahun 2012 hingga 2013 yakni hampir menyentuh angka 90% dari tahun sebelumnya. Dari hasil pengamatan pada trayek perjalanan Koridor II yang telah dilakukan, ternyata diketahui bahwa pada beberapa shelter (halte) terjadi permintaan yang cukup tinggi, dan akhirnya pada saat peak hour armada BRT tidak mampu menampung seluruh permintaan yang terjadi, sehingga mengakibatkan penumpang harus menunggu lebih lama untuk dilayani oleh armada tersebut. Hal tersebut memicu permasalahan baru yakni kurang optimalnya jumlah armada yang beroperasi dan juga jadwal antar keberangkatan armada yang kurang menyesuaikan kondisi ketika tingginya permintaan pada setiap halte. Adapun metode yang digunakan adalah dengan melakukan pendekatan sistem, yang selanjutnya melakukan pemodelan sistem transportasi dan simulasi computer yang terjadi pada rute perjalanan tersebut. Hasil dari penelitian ini adalah rancangan model simulasi dalam bentuk model matematis dan simulasi komputer. Variabel pengendali pada model matematis dan simulasi komputer adalah frekuensi waktu antar kedatangan armada BRT, sehingga diharapkan mengurangi panjang antrian penumpang. Kata kunci: sistem transportasi, pemodelan sistem, simulasi komputer.

Retaining Literature in the Indonesian ELT Curriculum
Authors: Puadi Ilyas Hamzah
Published: April 2017

This article presents serious independent arguments why literature needs to be retained in the Indonesian ELT (English Language Teaching) curriculum. In general, ELT curriculum nowadays seems to neglect the importance of literature since the introduction of the communicative approach. Three aspects are presented in connection with why the notion may need immediate application: (1) literature brings many advantages to Indonesian ELT learners; (2) literature can be used to teach critical thinking skills; and (3) critical thinking can be used to promote tolerance. This article is developed based on mainly the ideas of literature teaching proposed by Collie and Slater (1987), Lazar (1993), and Ghosn (2002). Hence, critical thinking and tolerance are values not getting serious attention in educational processes in this country even though these values have been included in the National educational objectives for Indonesia.

Authors: Kustian Nunu
Published: April 2017

Proses pengenalan wajah yang dilakukan oleh komputer tidak semudah dan secepat dibandingkan dengan proses pengenalan yang dilakukan oleh manusia. Manusia dengan mudah dapat mengenali wajah seseorang dengan sangat cepat tanpa rasanya harus berfikir. Input yang diperlukan pada aplikasi ini adalah berupa citra wajah dengan ukuran dan resolusi yang sama. Output aplikasi ini adalah berupa class terdekat dari wajah yang ingin dikenali. Aplikasi ini dibuat menggunakan MATLAB yang cukup handal dan mudah dalam perhitungan matematik dan bekerja dalam konsep matrik serta mempunyai fungsi  visualisasi yang bervariasi. Salah satu metode pendekatan yang digunakan adalah Eigenface, sebuah metode yang dikemukakan oleh Turk dan Pentland. Metode ini melibatkan sebuah set wajah yang pada dasarnya melibatkan proses analisis komponen utama (Principal Component Analysis). Dalam metode ini citra wajah akan diproyeksikan dalam sebuah ruang fitur yang menonjolkan variasi yang signifikan di antara citra wajah yang diketahui. Fitur signifikan inilah yang disebut dengan Eigenface karena fitur-fitur tersebut adalah komponen utama dari suatu set citra wajah untuk pelatihan. Hal yang perlu diingat adalah fitur-fitur ini tidak berarti berhubungan dengan fitur-fitur yang terdapat pada wajah, seperti mata, hidung, mulut, dan telinga. Eigenface hanya akan menangkap point-point pada citra yang menyebabkan variasi yang signifikan antara wajah-wajah dalam database yang membuat mereka dapat dibedakan.
Acute Mononeuropathy as the first presentation of Pediatric Type 1 Diabetes Mellitus: a case report
Authors: Kapoor Sonal , Sundaram Prem , Tziaferi Vaya , Prasad Manish
Published: April 2017

Background:

Prevalence of neuropathy in Diabetes in the pediatric age group is very low. Moreover, it is often a late complication of diabetes mellitus (DM) and usually related to the duration of diabetes, poor glycemic control and advanced age. We present here an interesting case of motor neuropathy as a first manifestation of Type 1 diabetes in an adolescent.

Case presentation:

A previously fit fourteen years old girl presented with sudden onset right foot drop. There was a history of osmotic symptoms and weight loss over the preceding last few months before presentation. Investigations revealed Type 1 diabetes mellitus. So, our patient was started on Multiple Daily Insulin Injection Regimen (MDI) as per protocol and the foot drop recovered within a period of two months.

Conclusion:

Mononeuropathy as a first presentation of diabetes is extremely rare. It is extremely important to assess the blood glucose in patients with peripheral neuropathy. Normalizing blood glucose levels leads to rapid neuronal recovery.
What Could Not Be Written: A Study of the Oral Transmission of Sayfo Genocide Memory Among Assyrians
Authors: Atto Naures
Published: April 2017

This article discusses the ways in which eyewitness accounts about the Assyrian Genocide have been transmitted in writing and orally, reconstructed across generations, and how these accounts have been expressed in lamentations, poetry, and songs in the diaspora, after large numbers of Assyrians settled in Western states beginning in the 1960s. The study of poetry and songs is not only important for reasons of literary analysis, but more so because of the relatively few written primary sources about the Assyrian Genocide. The production of poetry and songs has partly been instrumental in avoiding censorship and renewed persecution, but in recent years has additional value as a medium to call for future action in preventing violence and transmiting memories of the past. The article also highlights culturally specific forms of coping with trauma and transmitting memory. It is based on the analysis of Sayfo lamentations and poetry produced in the homeland, 21 Sayfo songs and poems produced in the Western diaspora, and some recent interviews with the writers of these songs.
Comparing lexical bundles across the introduction, method and results sections of the research article
Authors: Shahriari Hesamoddin
Published: April 2017

Despite the prolific amount of research into the discourse structure of the research article (RA), comparisons between the different sections of this important register have been extremely rare. This study is an attempt to analyse the structure and form of three main sections of the RA (i.e., Introduction, Method and Results) through examining the frequency, structure and function of lexical bundles found within each. By comparing the three sections, a better understanding of in-text linguistic variation (i.e., differences in the use of lexical bundles across the three sections) can be achieved. For this purpose, a corpus of 200 research articles in applied linguistics, segmented into the three sections noted above, was compiled. A list of four-word lexical bundles occurring at least thirty times per million words in the overall, one million-word corpus was made. Subsequently, each of the three sub-corpora was searched for any of the bundles on the list. The findings reveal the Results to be the most densely formulaic part of the RA, both in terms of the type/token frequency of bundles and the number of unique bundles that were not seen in any of the other sections. This section of the RA also included longer sequences of bundles than any other part. Structural and functional differences were also discovered among the three sections; some of these differences, especially in the distribution of various functional categories, indicated the existence of a close relationship between the discourse aims of a given section and the lexical bundles that are most characteristic of that part of the RA.
American television and off-screen registers: a corpus-based comparison
Authors: Sardinha Tony Berber , Pinto Marcia Veirano
Published: April 2017

In this paper, we present an analysis of a corpus of American television programmes, comprising 930 texts from 191 different TV programmes (excluding commercial breaks and infomercials), totalling 5,320,159 tokens. This analysis compares different programme types (live politics, movies, news desk, reality shows, etc.) against one another and against non-televisual registers (face-to-face conversations, telephone conversations, prepared speeches, press reviews, etc.), using the multidimensional (MD) approach to register variation ( Biber, 1988 ). The goal of this analysis is to determine how homogeneous/heterogeneous the language of television is as well as to how it compares to the registers of English ( Biber, 1988 ). We sought to detect both the similarities and differences among the TV registers and with respect to the five major dimensions of register variation previously identified by Biber (1988) . Linguistic studies of television language to date (e.g., Al-Surmi, 2012 ; Bednarek, 2010; Quaglio, 2009 ; and Rey, 2001 ) have generally focussed on few or individual TV registers. This study provides a much more comprehensive view of American television discourse by relying on a large multi-register corpus optimised for representativeness through the application of Biber's (1993) method for sampling adequacy. The results show distinct differences among the registers' dimensions, suggesting that, on the whole, present-day American TV language is varied and patterned. In addition, the findings indicate that several TV registers have close counterparts in off-screen communication, such as conversations, speeches and interviews. All things considered, this study shows in detail the contact and separation points across different TV registers, as well as across TV and off-screen registers.
Surgical stabilization of concomitant canine medial patellar luxation and cranial cruciate ligament disease
Authors: Fauron Albane , Bruce Mieghan , James Daniel , Owen Mark , Perry Karen
Published: April 2017

Objectives: To compare complication rates and outcomes between cases of concomitant cranial cruciate ligament (CrCL) disease and medial patellar luxation (MPL) treated using extracapsular stabilization and tibial tuberosity transposition (ECS+TTT) and tibial tuberosity transposition and advancement (TTTA).

Methods: In a multicentre retrospective study, records from four referral hospitals were reviewed for dogs with concomitant CrCL pathology and MPL treated using ECS+TTT or TTTA. Data retrieved included signalment, partial/complete CrCL tear, MPL grade, treatment performed, occurrence of postoperative complications, and postoperative outcome grade. Associations between surgical procedure and risk of complication and surgical procedure and outcome were investigated using univariable logistic regression and proportional odds logistic regression respectively. Multiple logistic regression was used to explore confounding factors.

Results: A total of 72 stifles were evaluated in 66 dogs; 32 stifles were stabilized using ECS+TTT and 40 using TTTA. Overall complications were 2.7 times more frequent in the ECS+TTT group and major complications occurred only in this group. The TTTA group was less likely to suffer complications (17.5%) compared to the ECS+TTT group (46.9%) (p = 0.009) and TTTA cases had lower odds of a poorer clinical outcome (p = 0.047).

Clinical significance: Stifles stabilized using ECS+TTT are more likely to suffer from postoperative complications and a poorer clinical outcome when compared to TTTA.

Authors: Deahl Lauren , Ben-Amotz Ron , Caceres Ana , Agnello Kimberly
Published: April 2017

Objective: To describe proximal tibial metaphyseal fractures in immature dogs.

Materials and methods: Medical records of immature dogs with metaphyseal fractures of the proximal tibia were reviewed and data were collected on signalment and history of trauma. Craniocaudal and mediolateral radiographs were evaluated for the determination of the bones fractured, location of the fracture within the bone, fracture configuration, and the presence of fracture segment displacement and angulation.

Results: Eighteen dogs with 22 proximal tibial metaphyseal fractures fulfilled the inclusion criteria. All fractures had a curvilinear, complete fracture of the proximal tibial metaphysis. Displacement was identified in 16 fractures and angulation in 15 fractures. All affected breeds were terrier or small breed dogs less than six months of age. The majority of dogs weighed 5 kg or less at the time of injury. The most common type of trauma that occurred was a jump or fall from a short distance.

Clinical significance: Proximal tibial metaphyseal fractures are an uncommon injury that occur in skeletally immature dogs from minimal trauma. Proximal tibial metaphyseal fractures have a characteristic curvilinear fracture configuration that affects mainly small breed dogs with a predominance for terrier breeds.

Fluorescent carbon dots from mono- and polysaccharides: synthesis, properties and applications
Authors: Hill Stephen , Galan M Carmen
Published: April 2017

Fluorescent carbon dots (FCDs) are an emerging class of nanomaterials made from carbon sources that have been hailed as potential non-toxic replacements to traditional semiconductor quantum dots (QDs). Particularly in the areas of live imaging and drug delivery, due to their water solubility, low toxicity and photo- and chemical stability. Carbohydrates are readily available chiral biomolecules in nature which offer an attractive and cheap starting material from which to synthesise FCDs with distinct features and interesting applications. This mini-review article will cover the progress in the development of FCDs prepared from carbohydrate sources with an emphasis on their synthesis, functionalization and technical applications, including discussions on current challenges.
Common Envelope Light Curves. I. Grid-code Module Calibration
Authors: Galaviz Pablo , Marco Orsola De , Passy Jean-Claude , Staff Jan E. , Iaconi Roberto
Published: April 2017

The common envelope (CE) binary interaction occurs when a star transfers mass onto a companion that cannot fully accrete it. The interaction can lead to a merger of the two objects or to a close binary. The CE interaction is the gateway of all evolved compact binaries, all stellar mergers, and likely many of the stellar transients witnessed to date. CE simulations are needed to understand this interaction and to interpret stars and binaries thought to be the byproduct of this stage. At this time, simulations are unable to reproduce the few observational data available and several ideas have been put forward to address their shortcomings. The need for more definitive simulation validation is pressing and is already being fulfilled by observations from time-domain surveys. In this article, we present an initial method and its implementation for post-processing grid-based CE simulations to produce the light curve so as to compare simulations with upcoming observations. Here we implemented a zeroth order method to calculate the light emitted from CE hydrodynamic simulations carried out with the 3D hydrodynamic code Enzo used in unigrid mode. The code implements an approach for the computation of luminosity in both optically thick and optically thin regimes and is tested using the first 135 days of the CE simulation of Passy et al., where a 0.8 M
⊙ red giant branch star interacts with a 0.6 M
⊙ companion. This code is used to highlight two large obstacles that need to be overcome before realistic light curves can be calculated. We explain the nature of these problems and the attempted solutions and approximations in full detail to enable the next step to be identified and implemented. We also discuss our simulation in relation to recent data of transients identified as CE interactions.
Effects of Preionization in Radiative Shocks. II. Application to the Herbig–Haro Objects
Authors: Dopita Michael A. , Sutherland Ralph S.
Published: April 2017

In an earlier paper we treated the preionization problem in shocks over the velocity range 20 km s−1 

km s−1  in a fully self-consistent manner. Here we investigate in detail the effect of the upstream UV photon field generated in the radiative zone of shocks in the range in which hydrogen is only partly ionized 20 km s−1 (

km s−1). We show that, as a result of superheating in the nonequilibrium preshock plasma, both the magnetic parameter and the Mach number of the shock are strongly affected by the preionization state of the gas, which controls to a large extent the radiative spectrum of the shock. We use these models to provide specific line diagnostics for Herbig–Haro objects, which allow us to solve for both the preshock density and shock velocity, and we present detailed models of the HH 34 jet, which allows us to derive the shock conditions, mass-loss rate, momentum flux, and chemical abundances in the jet. We show that the refractory elements Mg, Ca, Fe, and Ni are enhanced by 0.22 dex over the solar values, which provides interesting clues about the jet-launching mechanism in pre-main-sequence evolution.

The data are accurate enough for identification and deblending of new emission lines from the Sun and other astrophysical sources. The amount of high-accuracy data is significantly increased for the n = 3 states of several O-like ions of astrophysical interest, where experimental data are very scarce.

There is a thin transition region (TR) in the solar atmosphere where the temperature rises from 10,000 K in the chromosphere to millions of degrees in the corona. Little is known about the mechanisms that dominate this enigmatic region other than the magnetic field plays a key role. The magnetism of the TR can only be detected by polarimetric measurements of a few ultraviolet (UV) spectral lines, the Lyα line of neutral hydrogen at 121.6 nm (the strongest line of the solar UV spectrum) being of particular interest given its sensitivity to the Hanle effect (the magnetic-field-induced modification of the scattering line polarization). We report the discovery of linear polarization produced by scattering processes in the Lyα line, obtained with the Chromospheric Lyman-Alpha Spectro-Polarimeter (CLASP) rocket experiment. The Stokes profiles observed by CLASP in quiet regions of the solar disk show that the Q/I and U/I linear polarization signals are of the order of 0.1% in the line core and up to a few percent in the nearby wings, and that both have conspicuous spatial variations with scales of ∼10 arcsec. These observations help constrain theoretical models of the chromosphere–corona TR and extrapolations of the magnetic field from photospheric magnetograms. In fact, the observed spatial variation from disk to limb of polarization at the line core and wings already challenge the predictions from three-dimensional magnetohydrodynamical models of the upper solar chromosphere.
Perceptions on the use of a corporate business incubator to enhance knowledge management at Eskom
Authors: Steyn PD , Du Toit ASA
Published: April 2017

The knowledge economy impacts on the way enterprises should address their business requirements, forcing many of them to review the potential mechanisms they could employ to improve their competitive advantage. The business incubator approach is one such mechanism. This article explores the application of knowledge management, knowledge creation and innovation in a corporate incubator. It focuses on the process of knowledge management, to ensure that a culture and appropriate strategies conducive to enhancing knowledge creation are developed in an enterprise. Innovation as a strategic imperative is considered, as well as the challenge of driving it within an enterprise. The purpose of this empirical survey was to determine whether the corporate incubator model applied by Eskom conforms to the attributes of knowledge management, knowledge creation and innovation, and whether the synergies to be exploited amongst these disciplines can be harnessed to give Eskom a competitive advantage.
Employee perceptions of diversity management at a tertiary institution
Authors: Harris Chantel , Rousseau GG , Venter DLJ
Published: April 2017

Diversity is an inevitable aspect of organisational life, which has to be deal with at one time or other.  How employees perceive diversity impacts on their behaviour and therefore managing it is imperative.  The objective of this study was to investigate perceptions among staff members at a tertiary institution in the Eastern Cape of diversity management.  A further aim was to assist the institution in developing ways to improve diversity management.  A diversity management questionnaire was administered to employees to determine perceptions. Results confirmed that employees perceived a small number of diversity-related problems to be present.  Employees believed that the university understood the value of change and that they were in the non-discriminatory phase of evolution towards becoming multicultural.  A follow-up study in this field is necessary.
Measuring exchange market pressure in South Africa: an application of the Girton-Roper monetary model
Authors: Ziramba Emmanuel
Published: April 2017

The monetary approach to the balance of payments is based on the assumption of a fixed exchange rate, while its approach to exchange rate determination is based on perfectly flexible exchange rate. Another monetary model called the Exchange Market Pressure model (EMP) was designed to capture the properties of the managed float. This paper applies the monetary model of the EMP to the South African experience with floating exchange rate and managed float systems over the period 1970-1993. We show that the EMP model is superior to the traditional monetary approach. We do not find evidence of the impact of domestic real income on EMP. Diagnostic tests suggest that the model is well specified and the residuals pass the typical checking.
Rational expectations and the effects of financial liberalization on price level and output
Authors: Gupta Rangan
Published: April 2017

This paper develops a generalized short-term model of a small open financially repressed economy, characterized by unorganized money markets, intermediate goods imports, capital mobility, flexible exchange rates and rational expectations, to analyze the price- and output-effects of financial liberalization. The analysis shows that financial deregulation, in the form of increased rate of interest on deposits and higher cash reserve requirements, unambiguously and unconditionally reduces domestic price level, but fails to affect output. Moreover, the result does not depend on the degree of capital mobility. The paper recommends that a small open developing economy should deregulate interest rates and tighten monetary policy if reducing inflation is a priority. Such a policy, however, requires the establishment of a flexible exchange rate regime.
The challenge to reposition three divergent higher education institutions as a new comprehensive institution
Authors: Bresler Nerine
Published: April 2017

This study was designed to assist three higher education institutions that were forced into a merger to develop an identity, based on the unknown. A new type of organisation needs to be constructed in a changing environment. The paper presents the results of a survey of 654 stakeholders who were asked to indicate whether they associate any of the institutions with a list of 19 statements.The results are presented in a perceptual map to facilitate decision making. It depicts the merger partners as very different. This was confirmed by what the respective names triggered in respondents’ minds. The findings suggest issues management needs to address during the post-merger procedural integration to create and communicate value, through combined synergies, and to avoid some of the possible negative consequences of mergers.
Government revenue and expenditure nexus in South Africa
Authors: Nyamongo Esman , Schoeman Niek , Sichei Moses
Published: April 2017

This paper investigates the nexus between government expenditure and government revenue in South Africa within the framework of a vector autoregressive (VAR) approach. It uses the Hylleberg et al. (1990) method to test for seasonal unit roots and finds that government revenue and government expenditure have unit roots at all frequencies. The Johansen procedure test results reveal that these variables are cointegrated. It is further established that revenue and expenditure are linked bidirectionally by Granger causality in the long-run, while there is no evidence of Granger causalityin the short-run in South Africa.
Predictors of work-related well-being in sector education training authorities
Authors: Rothmann S , Pieterse AJH
Published: April 2017

The objective of this study was to investigate the relationship between job demands, job resources, sense of coherence and work-related well-being of employees at Sector Education Training Authorities (SETA). The sample consisted of 159 SETA employees in South Africa. The Maslach Burnout Inventory – General Survey, the Utrecht Work Engagement Scale, the Orientation to Life Questionnaire, and the Job Demands-Resources Scale. The results showed that overload predicted exhaustion. Cynicism was predicted by limited growth opportunities, a lack of organisational support, and a weak sense of coherence. Vigour and dedication were predicted by growth opportunities, organisational support and a strong sense of coherence.
Experiential learning and critical reflection as a tool for transfer of business knowledge: an empirical case study of a start-up simulation intervention for nascent entrepreneurs
Authors: Le Roux Ingrid , Steyn Barnard
Published: April 2017

This paper investigates the impact of venture start-up simulation on participants’ learning; it is concerned specifically with the relationship between experiential learning theory and critical reflection within venture start-up simulation. This was carried out in empirical investigation of a simulation training game used to train entrepreneurs in a formal setting. The findings show significant improvement in their knowledge of finance, marketing operations and information use. Participants reported increased skills and intended behavioural changes in their own ventures. Finally, there was empirical support for the fact that critical reflection during experiential learning can greatly improve the standard of learning and has an immediate effect on  participants’ behaviour.

Authors: James I , Hoffman T , Munro A , O'Farell P , Smart R
Published: April 2017

The travel cost method was used to estimate the economic recreational value of flower viewing at the Namaqua National Park. Demographic, time, expenditure, preference and route information was collected from interviews with 160 SA nationals who visited the park in their own car.  Visitors spent an average of $US108 on transportation and $US84 on accommodation in the region. A zonal travel cost model was developed which suggests that the economic recreational value of flower viewing at the park makes to the region is far larger than the annual net loss of $US50 000 which the park makes when only the expenses and revenue of the park are considered.
