Authors: Fernandes Sumardi , Adji Achmad Rinaldo Adji Achmad Rinaldo 
Published: February 2018

Purpose
The purpose of this paper is to analyze the relationship between management process alignment, service quality, organizational commitment and high educational performance.

Design/methodology/approach
The population of this study was all higher education institutions which provide undergraduate program and operate in Makassar. This study included a total sample of 312 respondents.

Findings
There is significant effects of mediation variables of service quality (M1) and organizational commitment (M2) on the relationship between management process alignment (X) and high educational performance (Y) in Makassar, Indonesia.

Research limitations/implications
For this study, cross-sectional data are used considering only one point of time due to which it is harder to see developments. There is a diversity of the characteristics of respondents, especially in terms of age, education, and status, so there is a possibility of a different perception of the content of the questionnaire that affected the selected answer.

Originality/value
This study considered the significant effects of mediation variables of service quality (M1) and organizational commitment on the relationship between management process alignment (X) and high educational performance. Previously, no research has been undertaken to examine the relationship between the location of the study and higher education institutions in the context of Makassar, Indonesia.
Impact of vapor polishing on surface quality and mechanical properties of extruded ABS
Authors: Neff Clayton , Trapuzzano Matthew , Crane Nathan B. 
Published: February 2018

Purpose
Additive manufacturing (AM) is readily capable of producing models and prototypes of complex geometry and is advancing in creating functional parts. However, AM processes typically underperform traditional manufacturing methods in mechanical properties, surface roughness and hermeticity. Solvent vapor treatments (vapor polishing) are commonly used to improve surface quality in thermoplastic parts, but the results are poorly characterized.

Design/methodology/approach
This work quantifies the surface roughness change and also evaluates the effect on hermeticity and mechanical property impacts for “as-printed” and acetone vapor-polished ABS tensile specimens of 1-, 2- and 4-mm thicknesses produced by material extrusion (FDM).

Findings
Vapor polishing proves to decrease the power spectral density for surface roughness features larger than 20 µm by a factor of 10× and shows significant improvement in hermeticity based on both perfluorocarbon gross leak and pressure leak tests. However, there is minimal impact on mechanical properties with the thin specimens showing a slight increase in elongation at break but decreased elastic modulus. A bi-exponential diffusion decay model for solvent evaporation suggest a thickness-independent and thickness-dependent time constant with the latter supporting a plasticizing effect on mechanical properties.

Originality/value
The contributions of this work show vapor polishing can have a substantial impact on the performance for end-use application of ABS FDM components.
The effect of different build orientations on the consolidation, tensile and fracture toughness properties of direct metal laser sintering Ti-6Al-4V
Authors: Alsalla Hamza Hassn , Smith Christopher , Hao Liang 
Published: February 2018

Purpose
The purpose of this paper is to study new process parameters which were selected to achieve the full density of Ti-6Al-4V samples in different building orientations and investigate fracture toughness property and its relation to the microstructure, an area which has not previously been reported in full detail and which may offer information to a designer. Direct metal laser sintering (DMLS) is an additive manufacturing technique that directly manufactures three-dimensional parts, layer-by-layer, to scan and melt metal powders for aerospace applications.

Design/methodology/approach
Hardness and tensile tests were carried out to evaluate the effect of consolidation on the mechanical performance of specimens made at three different building directions. Optical and electron microscopy were used to characterise the microstructure of the DMLS specimens and their effects on the fractures and mechanical properties.

Findings
It was found that the built samples have an excellent density at 4.5 g/cm, and the sample surfaces parallel to the building direction are rougher than the perpendicular surfaces. The fracture toughness result was higher than that of the cast material for the same alloy and higher than the Ti-6Al-4V parts fabricated by electron beam melting. This results in the superior mechanical properties of DMLS, while slightly lower in the zy direction owing to cracks, porosity and surface finish.

Research limitations/implications
The tensile strength was found to be higher than the wrought material, and the samples exhibited brittle fractures owing to the martensitic phase, which is caused by a high temperature gradient, and the mechanical properties change with the change in the microstructures at different building directions.

Originality/value
This paper contains original research.
Shear band propagation in honeycombs: numerical and experimental
Authors: Goodarzi Hosseinabadi Hossein , Bagheri Reza , Altstädt Volker 
Published: February 2018

Purpose
Hexagonal honeycombs with meso-metric cell size show excellent load bearing and energy absorption potential, which make them attractive in many applications. However, owing to their bend-dominated structure, honeycombs are susceptible to deformation localization. The purpose of this study is to provide insight about shear band propagation in struts of 3D-printed honeycombs and its relation to the achieved macroscopic mechanical behavior.

Design/methodology/approach
Hexagonal honeycombs and unit cell models are 3D-printed by fused deposition modeling (FDM). The samples are exposed to compression loading and digital image correlation technique and finite element analyses are incorporated.

Findings
It is found that the strain contours, which are obtained by finite element, are in agreement with experimental measurements made by DIC. In addition, three stages of shear band propagation in struts of 3D-printed honeycombs are illustrated. Then the correlation between shear band propagation stages and the achieved macroscopic mechanical responses is discussed in detail.

Originality/value
For the first time, a hierarchical activation of different modes of shear band propagation in struts of a 3D-printed honeycomb is reported. This information can be of use for designing a new generation of honeycombs with tailor-made localization and energy absorption potential.

On the other hand, the food security statistically influences the community welfare.Originality/valueUntil now there is no previous research that brings food security factors integrated with the community welfare, and no one has studied the full modeling on the Sumatra, Indonesia, and the use of SDGs data intact considering the new data of 2015 SDGs collected replacing the millennium development goals data.
Speech understanding in noise in elderly adults: the effect of inhibitory control and syntactic complexity
Authors: van Knijff Eline C. , Coene Martine , Govaerts Paul J. 
Published: February 2018

AbstractBackgroundPrevious research has suggested that speech perception in elderly adults is influenced not only by age‐related hearing loss or presbycusis but also by declines in cognitive abilities, by background noise and by the syntactic complexity of the message.AimsTo gain further insight into the influence of these cognitive as well as acoustic and linguistic factors on speech perception in elderly adults by investigating inhibitory control as a listener characteristic and background noise type and syntactic complexity as input characteristics.Methods & ProceduresPhoneme identification was measured in different noise conditions and in different linguistic contexts (single words, sentences with varying syntactic complexity). Additionally, inhibitory control was measured using a visual stimulus–response matching task. Fifty‐one adults participated in this study, including elderly adults with age‐related hearing loss (n = 9) and with normal hearing (n = 17), and a control group of normal hearing younger adults (n = 25).Outcomes & ResultsThe analysis revealed that elderly adults with normal hearing and with hearing loss were less likely to identify successfully phonemes in single words than younger normal hearing controls. In the context of sentences, only elderly adults with hearing loss had a lower odds of correct phoneme perception than the control group. Additionally, in elderly adults with hearing loss, phoneme‐in‐sentence perception was linked to age‐related declines in inhibitory control. In all participants, phoneme identification in sentences was influenced by both noise type and syntactic complexity.Conclusions & ImplicationsInhibitory control and syntactic complexity might play a significant role in speech perception, especially in elderly listeners. These factors might also influence the results of clinical assessments of speech perception. Testing procedures thus need to be selected and their results interpreted carefully with these influences in mind.
Unconventional monetary policy in the Asian financial crisis
Authors: Bayoumi Tamim , Gagnon Joseph 
Published: February 2018

AbstractSome of the policies central banks used during the Asian Financial Crisis had elements of unconventional monetary policy in that they involved the government buying assets that the private sector was unwilling to hold. We focus on public funding of bank recapitalizations in Thailand and the extraordinary purchase of equities in Hong Kong. Although it is important to calibrate these policies appropriately, we believe they helped to stabilize economies through channels that were not well understood at the time of the Asian crisis.

Published: February 2018

AbstractBackgroundThis study examined the combined effects of self‐monitoring of blood glucose (SMBG) and educational attainment on glycemic control in type 2 diabetes mellitus (T2DM) patients.MethodsA cross‐sectional survey was performed among community residents with T2DM. Good glycemic control was defined as HbA1c <7% in the most recent measurement. Multivariable logistic regression was used to examine associations of glycemic control with SMBG, educational attainment, and their combined effects by controlling for certain covariates, with further stratification by sex.ResultsComplete data were available for 798 patients, of which 58.52% had good glycemic control. Higher education and SMBG were associated with good glycemic control (P < 0.05). In the SMBG group, tertiary‐educated patients had the greatest odds of good glycemic control (odds ratios 2.56; 95% confidence interval 1.31–4.99). Among those performing SMBG, the odds of good glycemic control were higher for those with higher education levels (Ptrend = 0.003), whereas there was no clear trend for those not performing SMBG (Ptrend = 0.071). For subjects attaining secondary and tertiary education levels, the odds of good glycemic control were higher in those performing SMBG, although there was no significant difference between the two groups for those with a primary education. Glycemic control decreased slightly among males with a primary level education, but showed an increasing trend among females with a primary level education.ConclusionsSex‐specific educational disparities exist in the association between SMBG and glycemic control. More detailed guidelines for SMBG according to a subject's socioeconomic position and sex are required.

Published: February 2018

AbstractBackgroundA diet high in trans‐fatty acids (TFA) induces insulin resistance in rodent models and primates. However, previous epidemiological studies on the association between TFAs, based primarily on self‐reported intake from the diet, and diabetes in humans have yielded conflicting results. Herein we examined the associations of objectively measured plasma TFA concentrations with diabetes in a large population‐based study among US adults.MethodsWe included 3801 participants aged ≥20 years from the National Health and Nutrition Examination Survey 1999–2000 and 2009–10. Four major TFAs, namely palmitelaidic acid (C16:1 n‐7t), elaidic acid (C18:1 n‐9t), vaccenic acid (C18:1 n‐7t), and linolelaidic acid (C18:2 n‐6t, 9t), were measured in fasting plasma using gas chromatography–mass spectrometry. Diabetes was defined by self‐reported physician diagnosis, plasma fasting glucose ≥126 mg/dL, or HbA1c ≥6.5%.ResultsAfter adjustment for other major risk factors, the odds ratios (95% confidence intervals) of diabetes comparing the highest with lowest quintile of plasma TFAs was 2.19 (1.27–3.79) for total TFAs (Ptrend = 0.01), 2.34 (1.48–3.72) for elaidic acid (Ptrend = 0.0004), 1.33 (0.82–2.15) for linolelaidic acid (Ptrend = 0.18), 1.58 (0.97–2.58) for palmitelaidic acid (Ptrend = 0.02), and 1.64 (0.95–2.84) for vaccenic acid (Ptrend = 0.08). In addition, total TFAs, elaidic acid, palmitelaidic acid, and vaccenic acid were significantly associated with fasting glucose, fasting insulin, the insulin resistance index, and HbA1c.ConclusionsIn a nationally representative population, plasma TFAs, in particular elaidic acid, were positively associated with diabetes and biomarkers of glucose metabolism.
Neuronal ceroid lipofuscinosis in Salukis is caused by a single base pair insertion in CLN8
Authors: Lingaas F. , Guttersrud O‐A. , Arnet E. , Espenes A. 
Published: February 2018

SummaryNeuronal ceroid lipofuscinoses (NCLs) are heterogenic inherited lysosomal storage diseases that have been described in a number of species including humans, sheep, cattle, cats and a number of different dog breeds, including Salukis. Here we present a novel genetic variant associated with the disease in this particular breed of dog. In a clinical case, a Saluki developed progressive neurological signs, including disorientation, anxiety, difficulties in eating, seizures and loss of vision, and for welfare reasons, was euthanized at 22 months of age. Microscopy showed aggregation of autofluorescent storage material in the neurons of several brain regions and also in the retina. The aggregates showed positive staining with Sudan black B and periodic acid Schiff, all features consistent with NCL. Whole genome sequencing of the case and both its parents, followed by variant calling in candidate genes, identified a new variant in the CLN8 gene: a single bp insertion (c.349dupT) in exon 2, introducing an immediate stop codon (p.Glu117*). The case was homozygous for the insertion, and both parents were heterozygous. A retrospective study of a Saluki from Australia diagnosed with NCL identified this case as being homozygous for the same mutation. This is the fourth variant identified in CLN8 that causes NCL in dogs.

Aucubin protects against pressure overload‐induced cardiac remodelling via the β3‐adrenoceptor–neuronal NOS cascades
Authors: Wu Qing‐Qing , Xiao Yang , Duan Ming‐Xia , Yuan Yuan , Jiang Xiao‐Han , Yang Zheng , Liao Hai‐Han , Deng Wei , Tang Qi‐Zhu 
Published: February 2018

Background and PurposeAucubin, the predominant component of Eucommia ulmoides Oliv., has been shown to have profound effects on oxidative stress. As oxidative stress has previously been demonstrated to contribute to acute and chronic myocardial injury, we tested the effects of aucubin on cardiac remodelling and heart failure.Experimental ApproachInitially, H9c2 cardiomyocytes and neonatal rat cardiomyocytes pretreated with aucubin (1, 3, 10, 25 and 50 μM) were challenged with phenylephrine. Secondly, the transverse aorta was constricted in C57/B6 and neuronal NOS (nNOS)‐knockout mice, then aucubin (1 or 5 mg·kg−1 body weight day−1) was injected i.p. for 25 days. Hypertrophy was evaluated by assessing morphological changes, echocardiographic parameters, histological analyses and hypertrophic markers. Oxidative stress was evaluated by examining ROS generation, oxidase activity and NO generation. NOS expression was determined by Western blotting.Key ResultsAucubin effectively suppressed cardiac remodelling; in mice, aucubin substantially inhibited pressure overload‐induced cardiac hypertrophy, fibrosis and inflammation, whereas knocking out nNOS abolished these cardioprotective effects of aucubin. Blocking or knocking down the β3‐adrenoceptor abolished the protective effects of aucubin in vitro. Furthermore, aucubin enhanced the protective effects of a β3‐adrenoceptor agonist in vitro by increasing cellular cAMP levels, whereas treatment with an adenylate cyclase (AC) inhibitor abolished the cardioprotective effects of aucubin.Conclusions and ImplicationsAucubin suppresses oxidative stress during cardiac remodelling by increasing the expression of nNOS in a process that requires activation of the β3‐adrenoceptor/AC/cAMP pathway. These findings suggest that aucubin could have potential as a treatment for cardiac remodelling and heart failure.
Translocality, Network Structure, and Music Worlds: Underground Metal in the United Kingdom
Authors: Emms Rachel , Crossley Nick 
Published: February 2018

AbstractTranslocal music worlds are often defined as networks of local music worlds. However, their networked character and more especially their network structure is generally assumed rather than concretely mapped and explored. Formal social network analysis (SNA) is beginning to attract interest in music sociology but it has not previously been used to explore a translocal music world. In this paper, drawing upon a survey of the participation of 474 enthusiasts in 148 live music events, spread across 6 localities, we use SNA to explore a significant “slice” of the network structure of the U.K.'s translocal underground heavy metal world. Translocality is generated in a number of ways, we suggest, but one way, the way we focus upon, involves audiences traveling between localities to attend gigs and festivals. Our analysis of this network uncovers a core‐periphery structure which, we further find, maps onto locality. Not all live events enjoy equal standing in our music world and some localities are better placed to capture more prestigious events, encouraging inward travel. The identification of such structures, and the inequality they point to, is, we believe, one of several benefits of using SNA to analyze translocal music worlds.
