Design of the competitiveness model in leather tanning industry

The Indonesian leather industry has low competitiveness among ASEAN Countries. The government, entrepreneurs, and researchers are trying to find solutions to improve competitiveness. However, there are differences in understanding the dimensions of competitiveness. This research aims to con¬struct and validate the competitiveness model in the manufacturing industry. In general, the concept of competitiveness is more oriented to the final result than to the process dimension. To improve competitiveness, this study using a manufacturing strategy approach based on process capability. The design of the competitiveness model contains the relationship between exogenous and endogenous variables with formative patterns. Exogenous variables are dimensions that makeup competitiveness, consisting of resources, operational processes, and performance. The data were obtained from 42 leather tanning factories in Indonesia, which was analyzed using Partial Least Square. This study reveals that industrial competitiveness is influenced by the dimensions of resources, operational pro¬cesses, and performance, where the dimensions of operational processes have a greater influence. This research confirms that the government and entrepreneurs must prioritize process capabilities to improve their competitiveness.

Mixed Vehicular Traffic Flow Model on an Inclined Multilane Road

This study outlines the Kerner’s 3 phase traffic flow theory, which states that traffic flow occurs in three phases and these are free flow, synchronized flow and wide moving jam phase. A macroscopic traffic model that is factoring road inclination is developed and its features discussed. By construction of the solution to the Rienmann problem, the model is written in conservative form and solved numerically. Using the Lax-Friedrichs method and going ahead to simulate traffic flow on an inclined multi lane road. The dynamics of traffic flow involving cars(fast moving) and trucks(slow moving) on a multi-lane inclined road is studied. Generally, trucks move slower than cars and their speed is significantly reduced when they are moving uphill on an in- clined road, which leads to emergence of a moving bottleneck. If the inclined road is multi-lane then the cars will tend to change lanes with the aim of overtaking the slow moving bottleneck to achieve free flow. The moving bottleneck and lanechange ma- noeuvres affect the dynamics of flow of traffic on the multi-lane road, leading to traffic phase transitions between free flow (F) and synchronised flow(S). Therefore, in order to adequately describe this kind of traffic flow, a model should incorporate the effect of road inclination. This study proposes to account for the road inclination through the fundamental diagram, which relates traffic flow rate to traffic density and ultimately through the anticipation term in the velocity dynamics equation of macroscopic traffic flow model. The features of this model shows how the moving bottleneck and an incline multilane road affects traffic transistions from Free flow(F) to Synchronised flow(S). For a better traffic management and control, proper understanding of traffic congestion is needed. This will help road designers and traffic engineers to verify whether traffic properties and characteristics such as speed(velocity), density and flow among others determines the effectiveness of traffic flow.
There is Nothing Magical about Bayesian Statistics: An Introduction to Epistemic Probabilities in Data Analysis for Psychology Starters

Abstract This paper is a reader-friendly introduction to Bayesian inference applied to psychological science. We begin by explaining the difference between frequentist and epistemic interpretations of probability that underpin respectively frequentist and Bayesian statistics. We use a concrete example—a student wondering whether s/he carries the virus statisticus malignum—to explain how both approaches are different one from another. We illustrate Bayesian inference with intuitive examples, before introducing the mathematical framework. Different schools of thoughts and recommendations are discussed to illustrate how to use priors in Bayes Factor testing. We discuss how psychology could benefit from a greater reliance on Bayesian methods. Finally, we illustrate how to compute Bayes Factors analyses with real data and provide the R code.
Microalgal Pigments Carotenoids and Chlorophyll as Potential Natural Colorants to Cakes

The study was conducted to determine the suitability of carotenoid and chlorophyll pigments of the freshwater microalgae, Scenedesmus sp. as natural cake colorants to replace synthetic ones. First, the pigments were extracted from microalgal powder to be used in evaluating its concentration and also its antioxidant activities by DPPH assay. The microalgal powder and synthetic colorant were incorporated into two different cakes. Both cakes were used to perform color analysis, and sensory test to assess the consumer acceptance towards the enhanced microalgal butter cake. The results showed microalgal powder contained 4.16 ± 0.012 mg/g of chlorophyll a, 3.30 ± 0.005 mg/g of chlorophyll b and 0.40 ± 0.003 mg/g of carotenoids. Screening of antioxidant activities through DPPH assay showed lower antioxidant activities (10.93 ± 0.59 %) of the microalgal extract than commercial antioxidant (51.79 ±14.2%). However, the color analysis proved that microalgal powder provided a more intense (p L*: -a*: >b*) to the cake as compared to synthetic colorant. Sensory test also depicted no significant difference (p>0.05) on the preferrence by the panelists between normal cake with synthetic color or cake with microalgal powder as colorant. The result of this study revealed a good potential of using microalgal powder as colorant for cake and pastry preparation.
Online optical monitoring of polymer melting in a twin‐screw extruder

Funding information Conselho Nacional de Desenvolvimento Científico e Tecnológico, Grant/Award Number: 311790/2013-5; Coordenaç~ao de Aperfeiçoamento de Pessoal de Nível Superior, Grant/Award Numbers: Finance Code 001, PDSE 88881.132167/2016-01, PVE 30484/2013-01 Abstract An experimental setup containing a sliding online optical device is used to monitor in real-time the melting process of a commercial polypropylene in a corotating intermeshing twin-screw extruder. Turbidity and birefringence are measured at several axial locations upstream and along the first restrictive zone of the screw, where melting develops. The experiments are performed using different set barrel temperatures, extruder feed rates, and screw speeds, to generate distinct flow histories and, accordingly, changes in the onset and rate of melting of the polymer. The local flow conditions are characterized in terms of residence time distribution and data equivalent to axial pressure profiles. Turbidity and birefringence are sensitive to changes in the operating conditions providing a coherent description of melting. The onset of melting seems to take place in partially filled conveying elements, and then melting develops quickly as the latter become fully filled, and is completed well before flow through the kneading block.
Supplier Selection Criteria and Methods in Supply Chain (A Statistical Approach)

In today’s competitive environment, vendor selection is considered as a strategic issue in the effective management of a supply chain. Keeping in view the strategic importance of the supplier’s role in the functioning of supply chains the researchers have developed number of criteria, methods and models for supplier selection. This study involves a comprehensive review of different methods of supplier selection available in the literature and suggests a new approach based on statistical analysis on different characteristics of the supplier. The suggested approach includes the use of Multivariate analysis of variance and Duncan’s multiple range test to assess the variations of the suppliers with respect to their different quality characteristics and use of desirability function to measure the performance status of different suppliers considering all the critical characteristics. The calculated desirability value measured in a 0-1 scale provides a single performance index for each supplier. The methodology was implemented in an Indian industry. It has an immense scope of application in supplier selection problem to improve the performance of supply chain management system. Keywords—vendor selection criteria, multivariate ANOVA, desirability function

Constructing and measuring of the critical success factors of college students international mobility: Application of Analytic Hierarchy Process (AHP) method

With the increasing popularity and importance of globalization issues, “global mobility” has become one of the important education policies of Taiwan's higher education. Many universities have actively applied “Shuei-Hai-Fei-Yan” and “Shuei-Hai-Shi-Jhu” programs to follow the trend of globalization and arrange outstanding students to participate in overseas training or internships in order to strengthen the cultivation of university students' global mobility. However, under the impact of the trends of “globalization”, “lower birth rate” and “digitalization”, it is necessary to explore the critical success factors of global mobility of college students. This study takes a teacher and Student University in southern Taiwan as the research object, and applies Analytic Hierarchy Process (AHP) and questionnaires on 11 experts and 174 students. The results of the study found that: (1) the major aspects of factors for teachers using AHP to recognize the critical success factors of university students’ international mobility are “environmental adaptability”, “international language skills”, “challenges and adventures”, and “global vision”; the perspectives of college students are “challenging and adventurous”, “global vision”, “environmental adaptability”, and “international language ability”; (2) AHP experts recognize that among the 13 key elements of the secondary aspect of the key success factors for international mobility of college students, their weights are ranked in the top five in sequence: “fluent international language or oral expression ability”, “oversea life adaptability”, “clear message conveyed in international languages”, “overseas psychology adaptability”, “adaptability for overseas work/study abroad”; and the perspective of university students is “multicultural tolerance or acceptance”, “try or experience new things”, “dare to challenge difficult tasks”, “cross-cultural thinking perspective”, and “without the fear of risks or failure”. Key words: College students, international mobility, T-type talent, critical success factors.
Biomimetic Nanocomposites Cloaked with Bioorthogonally Labeled Glioblastoma Cell Membrane for Targeted Multimodal Imaging of Brain Tumors

Brain tumor targeted delivery of diagnostic contrast agents has been an elusive goal due to the presence of the blood brain barrier (BBB) and the complex brain tumor microenvironment. Herein, an ingenious design of nanoscale contrast agents coated by bioorthogonally labeled brain tumor cell membrane for targeted diagnosis of glioblastoma through multiple complementary imaging modalities is presented. Taking advantage of bioorthogonal click reactions, an endothelial integrin receptor‐targeting peptide cRGD is decorated onto the nanocomposite surface to act in synergy with brain tumor cell membrane to offer BBB‐penetrating and homotypic targeting effect in the brain tumor microenvironment. Cellular and animal experimental results validate the superior targeting outcomes achieved by cRGD‐labeled brain tumor cell membrane coating. This study offers an example of a surface modified cell membrane as a potential theranostic strategy to overcome the delivery barriers in brain tumors.
Global modeling of heterogeneous hydroxymethanesulfonate chemistry

Abstract. Hydroxymethanesulfonate (HMS) has recently been identified as an abundant organosulfur compound in aerosols during winter haze episodes in northern China. It has also been detected in other regions although the concentrations are low. Because of the sparse field measurements, the global significance of HMS and its spatial and seasonal patterns remain unclear. Here, we modify and add to the implementation of HMS chemistry in the GEOS-Chem chemical transport model and conduct multiple global simulations. The model accounts for cloud entrainment and gas–aqueous mass transfer within the rate expressions for heterogeneous sulfur chemistry. Our simulations can generally reproduce quantitative HMS observations from Beijing and show that East Asia has the highest HMS concentration, followed by Europe and North America. The simulated HMS shows a seasonal pattern with higher values in the colder period. Photochemical oxidizing capacity affects the competition of formaldehyde with oxidants (such as ozone and hydrogen peroxide) for sulfur dioxide and is a key factor influencing the seasonality of HMS. The highest average HMS concentration (1–3 µg m−3) and HMS ∕ sulfate molar ratio (0.1–0.2) are found in northern China in winter. The simulations suggest that aqueous clouds act as the major medium for HMS chemistry while aerosol liquid water may play a role if its rate constant for HMS formation is greatly enhanced compared to cloud water.
HETEROCYCLES 45. SYNTHESIS, CHARACTERIZATION AND BIOLOGICAL EVALUATION OF 3-INDOLYL-1-PYRIDYL-2- PROPENONES AS ANTICANCER AGENTS

A series of seven 3-indolyl-1-pyridyl-2-propenones were synthesized via Claisen-Schmidt condensation with 68.8-91.8% yields. All the synthesized compounds were purified and characterized by melting points, IR, H NMR, C NMR and HRMS. The cytotoxicity of the synthesized 3-indolyl-1-pyridyl-2-propenones 1-7 and doxorubicin, used as positive control, was determined in a panel of nine human cancer cell lines including both sensitive and drug-resistant phenotypes, as well as in normal AML12 hepatocytes. Compounds 3, 4 and 7 displayed half maximal inhibitory concentration (IC50) values below 100 μM in all tested cancer cell lines meanwhile, other compounds displayed selective activities.
Sexual health and Risk-Taking behaviors among New York city high school students: variation by sexual orientation and gender identity status

Abstract Few sexual health studies have examined subgroup differences in youth risk behaviors that sufficiently account for sexual orientation and gender identity. This study used 2017 New York City Youth Risk Behavior Survey data (N = 10,191), a stratified cluster-sampled survey, to examine descriptive differences in the prevalence of risky sexual behaviors, such as failing to use contraception and engaging in sexual activity while intoxicated, among others. Weighted logistic regression analyses revealed that LGBTQ youth were more likely to engage in risky sexual behaviors than non-LGBTQ youth, placing them at increased risk of pregnancy, sexually transmitted infections (STIs), and human immunodeficiency virus (HIV). Results suggest the need for prevention and intervention programs, and more fundamentally, basic health education and care for these adolescents whose risk for sexual and reproductive health concerns outweighs their non-LGBTQ peers.
A SOM‐based analysis of the drivers of the 2015–2017 Western Cape drought in South Africa

The multi‐year (2015–2017) drought in the South West of the Western Cape (SWC) caused a severe water shortage in the summer of 2017–2018, with damaging impacts on the local and regional economy, and Cape Town being in the news one of the first major cities to potentially run out of water. Here, we assess the links between the rainfall deficits during the drought and (a) large scale circulation patterns, (b) moisture transport, and (c) convective available potential energy (CAPE). We used self‐organising maps (SOM) analysis to classify daily ERA‐interim 850 hPa geopotential height for the period 1979–2017 (March–October) into synoptic types. This allowed us to identify the dominant synoptic states over Southern Africa that influence the local climate in the area affected by the drought. The results show that (a) the frequency of nodes with rain‐bearing circulation types decreased during the drought; (b) the amount of rain falling on days that did have rain‐bearing circulation types was reduced, especially in the shoulder seasons (March–May and August–October); (c) the rainfall reduction was also associated with anomalously low moisture transport, and convective energy (CAPE), over SWC. These results add to the existing knowledge of drivers of the Cape Town drought, providing an understanding of underlying synoptic processes.
Plasmonic Photocatalysts for Microbiological Applications

Wide-bandgap semiconductors modified with nanostructures of noble metals for photocatalytic activity under vis irradiation due to localized surface plasmon resonance (LSPR), known as plasmonic photocatalysts, have been intensively investigated over the last decade. Most literature reports discuss the properties and activities of plasmonic photocatalysts for the decomposition of organic compounds and solar energy conversion. Although noble metals, especially silver and copper, have been known since ancient times as excellent antimicrobial agents, there are only limited studies on plasmonic photocatalysts for the inactivation of microorganisms (considering vis-excitation). Accordingly, this review has discussed the available literature reports on microbiological applications of plasmonic photocatalysis, including antibacterial, antiviral and antifungal properties, and also a novel study on other microbiological purposes, such as cancer treatment and drug delivery. Although some reports indicate high antimicrobial properties of these photocatalysts and their potential for medical/pharmaceutical applications, there is still a lack of comprehensive studies on the mechanism of their interactions with microbiological samples. Moreover, contradictory data have also been published, and thus more study is necessary for the final conclusions on the key-factor properties and the mechanisms of inactivation of microorganisms and the treatment of cancer cells.
Writing a manuscript for publication: An action research study with allied health practitioners

Introduction: Writing a manuscript for publication is a challenge for those health practitioners whose primary role is to provide clinical services. The aim of this study was to increase the capacity of allied health practitioners who are employed in a clinical setting to submit manuscripts for publication in peer-reviewed journals. Methods: An action research study design was used to develop a “Writing for Publication” program for nine allied health practitioners who had not previously published a manuscript as lead author. Between May and November 2018, at a regional public hospital service, three 90-minute writing workshops were offered, which included manuscript plan and preparation guide, academic writing instruction, peer review and mentoring by experienced researchers. Data were collected using participant pre- and post-program surveys, post-workshop focus groups and facilitator reflections. Results: All participants reported that their writing skills had improved. Enablers to completing a manuscript for publication included structured preparation, mentoring, training in academic writing skills, protected writing time and external accountability. Challenges included not knowing where or how to start, competing priorities and distractions within and outside of work hours, inadequate academic writing skills and loss of momentum. Two participants submitted their manuscripts for publication by the end of the study and a further manuscript was submitted by the time of writing. Conclusions : Strategies to ensure publication of allied health practitioner research findings need to be integrated into project planning and monitoring processes embedded within a well-supported health service-wide research culture.
