Blo-Wiper: From Conceptual Design to Computer Simulation Analysis for New National Car Development Project (A Case Study for Malaysia Small Medium Enterprise-SME)
Authors: Mohtar Muhammad Zaidi bin
Published: February 2019

Blo-Wiper is a project proposed by Techno Brozek Enterprise to Malaysian government in 3rd National Car Project (NNCP). According to a feasibility study conducted by them, conventional windshield wiper is less effective during heavy rains especially for countries located at equatorial. They came out with Blo-Wiper idea which is a novel system that combined two mechanisms; wiping and blowing. Their first white paper is covered on feasibility study and concept development. Then, they continue their Research and Development (R&D) from conceptual design to computer simulation analysis by using Proof of Concept (PoC) process. Interaction of rain droplets with blowing air is simulated by using Computational Fluid Dynamics(CFD). CFD result for windshield wiper with blowing air proven that rain droplets are shattered and repelled towards left and right of boundary layer. Meanwhile, without air blowing, the rains droplets falling down on floor boundary layer. Rain Droplets Removing Width (RDRW) for a system with wiping and blowing is 76mm while conventional system is zero. That means, Blo-Wiper mechanisms; wiping and blowing is better than conventional mechanism; wiping only. The objective of this white paper is to publish R&D progress which is development from conceptual phase to numerical simulation phase.

Gradations in task engagement emerge from metacognitive priority control
Authors: Mussack Dominic , Schrater Paul
Published: February 2019

Engagement is a critical motivational factor that has broad effects on learning, productivity, performance, and even satisfaction and happiness. However, engagement can be impacted by a myriad of factors including the features of the task, the broader environment and the person’s needs and biological states. Engagement has been difficult to characterize and measure, resulting in domain-specific conceptualizations and models that vary widely, creating a disconnected view of the overall phenomena of task engagement. Here we address this problem by developing an integrated metacognitive framework for understanding task engagement. We identify the key phenomenal characteristics of task engagement as integrating a graded effort for ongoing tasks with the temporal dynamics of task switching. We treat engagement as resulting from a unified meta-cognitive decision process that handles the gradient of engagement as resulting from a common priority calculation, the equivalent of an overall utility rate for ongoing tasks. Priority signals are computed relative to a set of available tasks and updated across time and changes in the environment. We propose a metacognitive controller makes decisions about both task switching (when to quit, next task) and cognitive resourcing (working memory, attention, etc) using the graded priority signals. By simultaneously choosing the task and allocating resources using the same graded signals, we capture the complex dependencies of engagement with task errors, performance, and time allocation.
Identifying Heterogeneity in Dynamic Panel Models with Individual Parameter Contribution Regression
Authors: Arnold Manuel , Oberski Daniel Leonard , Brandmaier Andreas Markus , Voelkle Manuel
Published: February 2019

Dynamic panel models are a popular approach to study interrelationships between repeatedly measured variables. Often, dynamic panel models are specified and estimated within a structural equation modeling (SEM) framework. An endemic problem threatening the validity of such models is unmodelled heterogeneity. Recently, individual parameter contribution (IPC) regression was proposed as a flexible method to study heterogeneity in SEM parameters as a function of observed covariates. In the present paper, we derive how IPCs can be calculated for general maximum likelihood estimates and evaluate the performance of IPC regression to estimate group differences in dynamic panel models in discrete and continuous time. We show that IPC regression can be slightly biased in samples with large group differences and present a bias correction procedure. IPC regression showed generally promising results for discrete time models. However, due to highly nonlinear parameter constraints, caution is indicated when applying IPC regression to continuous time models.
A Bottom-up picture of Intra-National Welfare Regimes: The case of Marginalised Communities in Puerto Rico
Authors: Cruz-Martinez Gibran
Published: February 2019

The main purpose of this article is twofold: (1) an examination of welfare regimes using a bottom-up approach, which enables a comprehensive analysis of welfare production based on recipients perceptions; and (2) an examination of more than one type of welfare-mix coexisting inside the national level across policy sectors. A classification of welfare regimes is carried out following a bottom-up approach and relying on the basis of the importance of welfare providers to satisfy social risks and promote well-being. Three traditional (e.g., state, market, family) and one alternative welfare provider (e.g., community) are considered. Data is collected through twenty semi-structured interviews in seven marginalised communities of Puerto Rico. The results show five configurations of intra-national welfare-mixes across the following welfare areas: housing, nourishment, health, education, maternity/paternity, disability, work-unemployment and older-age. This paper contributes to the theoretical proposals of intra-national welfare regimes, and alternatives providers in the welfare-mix.

Paper Cuts: How Reporting Resources Affect Political News Coverage
Authors: Peterson Erik
Published: February 2019

Media outlets provide crucial inputs into the democratic process, yet they face increasingly severe economic challenges. I study how a newly salient manifestation of this pressure, reduced reporting capacity, influences political coverage. Focusing on newspapers in the United States, where industry-wide employment fell over 40% between 2007 and 2015, I use panel data to assess the relationship between reporting capacity and political coverage. Staff cuts substantially decrease the amount of political coverage newspapers provide. Across different samples and measurement approaches, a typical cutback to a newspaper's reporting staff reduces its annual political coverage by between 300 and 500 stories. These political news declines happen against the backdrop of similar reductions in non-political coverage, meaning the share of newspaper articles focused on politics remains stable over this period. This demonstrates that economic pressure affects the political information environment by shaping the media's capacity to cover politics.
Revenue-Generating Potential of Taxation for Older-Age Social Pensions
Authors: Cruz-Martinez Gibran
Published: February 2019

Read it for free: http://rdcu.be/ub6J Social security and taxation operate jointly to overcome individual deprivations, reduce income inequality and promote development, bringing 'taxation into social protection analysis and planning'. There are several ways in which governments can create fiscal space to finance social protection programmes (e.g. social pensions). The idea is to create new sources of revenue –sustainable in the long-run – which can be used to finance social pensions, without building new liabilities and without distorting macroeconomic stability. The literature specifically addressing the potential fiscal space that could be created to finance social pensions is limited. This paper aims to begin filling some of those gaps and identify sources for creating fiscal space for social pensions through the revenue side (i.e. examine the revenue-generating potential of taxation for social pensions). Specifically, examine the potential funding power of three types of taxes (income tax, corporate tax, and trade tax) using cross-country tax revenues and tax rate data in a global perspective. The paper demonstrates that the three taxes have a revenue-generating potential to finance social pensions in several countries. There is not a magic prescription useful for every country, but there are numerous options to design a tailored mix of sources to create fiscal space. *This study was funded by Help Age International, while the author was a Research Fellow.
Esfuerzo de bienestar y pobreza desde el enfoque monetarista y de capacidades: Análisis transnacional en América Latina y el Caribe (1990-2010)
Authors: Cruz-Martinez Gibran
Published: February 2019

Existe una abundante evidencia empírica sobre la relación negativa entre el esfuerzo de bienestar y la pobreza. Sin embargo, los indicadores de pobreza tradicionalmente utilizados han sido representativos del enfoque monetarista, excluyendo del análisis su realidad multidimensional. Utilizando tres técnicas de regresión para el periodo 1990 2010 y controlando por factores demográficos y cíclicos, en este trabajo se ha evaluado la relación entre esfuerzo de bienestar en términos de gasto social per cápita y la pobreza en 21 países de la región. Para medir la pobreza desde el enfoque monetarista se han considerado dos indicadores: la proporción de población con ingresos inferiores a la canasta básica de alimentos y servicios (PM1) y la proporción de población con ingresos inferiores al 50% de la mediana de ingresos per cápita (PM2). Desde el enfoque de capacidades se ha valorado la proporción de población con insuficiencia alimentaria (PC1) y la proporción de la población sin acceso a agua potable ni servicio de saneamiento (PC2). Los resultados confirman que el gasto social es útil para explicar los cambios en la pobreza (PM1, PC1 y PC2), ya que existe una alta correlación negativa y significativa entre las variables antes y después de controlar para factores demográficos y cíclicos. En dos de las técnicas de regresión el gasto social per cápita no presentó una relación negativa con la variable PM2. Por último, el gasto social per cápita fue el más útil para explicar los cambios en la pobreza desde el enfoque de capacidades.
Welfare State Development, Individual Deprivations and Income Inequality: A cross-country analysis in Latin America and the Caribbean
Authors: Cruz-Martinez Gibran
Published: February 2019

Several scholars have confirmed the role that the welfare state (WS) plays in reducing poverty, promoting equality and ensuring the common wellbeing. One of the limitations of the scholarship has been the conceptualization and operationalization of the WS and poverty as one-dimensional variables. The purpose of this paper is to examine the relationship between welfare state development, single-dimensions deprivations and income inequality in Latin America and the Caribbean, before and after controlling for demographic and cyclical factors. The WS is operationalized as a one-dimensional variable, but also taking into account its multidimensional nature. Three individual deprivations suffered by people on poverty and two income inequality indicators are used as dependent variables. Three pooled time-series cross-section regression analyses with panel-corrected standard errors models were carried out on 18 countries in the region around 2000, 2005 and 2010. This paper shows that the development of social-welfare programs and institutions seems to be an effective way of tackling individual deprivations suffered by people on poverty in the region. On the other hand, the WS development didn’t appear to be effective to reduce income inequality. The outcomes of welfare institutions appear to be the pivotal dimension to reduce income inequality and income deprivations in the region.
Sequential Farkas lemmas for convex systems
Authors: Nguyen Dinh , Tran Mo Hong
Published: February 2019

In this paper we introduce two new versions of Farkas lemma for two kinds of convex systems in locally convex Hausdorff topological vector spaces which hold without any constraint qualification conditions. These versions hold in the limits and will be called sequential Farkas lemmas. Concretely, we establish sequential Farkas lemmas for cone-convex systems and for systems which are convex with respect to a sublinear function. The first result extends some known ones in the literature while the second is a new one.
278 Ma U-Pb zircon age of metagranite in Bo Xinh complex area of song Ma structural zone and its significances
Authors: Pham Hieu Trung
Published: February 2019

Zircons separated from an meta-granite dyke sample in the Bo Xinh complex area were dated to determine the protolith age for the complex. Nine LA-ICP-MS U-Pb zircon analyses give concordant ages concentrated at 278 Ma (weighted mean). These results indicated the protolith age of the metagranite dyke (primary magma crystallization age). These meta-granite dyke penetrated the mafic rocks of Bo Xinh complex, therefore it can be confirmed that the crystallization age of the mafic rocks of Bo Xinh complex must be older than 278 Ma (early Permian).

KADAR BESI SERUM, SATURASI BESI DAN TOTAL IRON BINDING CAPACITY PADA TIKUS PUTIH BETINA (Rattus norvegicus) AKIBAT PEMBERIAN ZAT BESI BERSAMA KALSIUM
Authors: Hermawan Dessy
Published: February 2019

Kalsium dan zat besi sering diberikan bersama-sama baik dalam bentuk makanan/minuman ataupun obat-obatan. Padahal penyerapan kalsium di dalam usus menggunakan divalen metal transforter 1 (DMT 1) yang juga digunakan oleh zat besi, sehingga dapat menimbulkan hambatan kompetitif diantara keduanya. Penelitian ini bertujuan untuk mengkaji seberapa besar kadar kalsium terendah yang menyebabkan penyerapan besi terhambat, sehingga akan berdampak pada kadar besi serum, TIBC & saturasi besi.Penelitian ini merupakan penelitian eksperimen sederhana : pre post test group control design. Subyek penelitian adalah tikus putih betina (Strain Wistar Rattus norvegicus) yang berumur 8 minggu dengan BB 125-150 mg. Sebelum diberikan perlakukan, tikus diukur profil besi darahnya, kemudian dibuat menjadi anemia defisiensi besi dengan diambil darahnya secara rutin 2 kali seminggu selama 1 bulan. Kemudian sampel dibagi menjadi 5 kelompok dan diberi perlakukan selama 7 hari. Sebelum dan sesudah perlakuan, tikus diukur kadar besi serum, saturasi besi & total iron binding capacity. Kesimpulan dari penelitian ini adalah pada pada kondisi tikus yang mengalami anemia defisiensi besi, kadar kalsium 50 mg/hari sudah mulai terjadi penghambatan penyerapan besi dan tampak sangat nyata pada kadar 75 mg/hari (1 72 kali dari angka kecukupan normal). Semakin tinggi kadar kalsium yang diberikan peroral, maka akan semakin rendah besi yang dapat diserap oleh usus, sehingga tidak akan mampu meningkatkan kadar besi serum, saturasi besi dan menurunkan TIBC.

rom EEOR, Electro Enhanced Oil Recovery, and a developing technology application which has been established earlier. The difference is ESOR relatively does not improve recovery factor of producing well. Ideally any crude oil producing well will be experiencing pressure decline which may affect crude oil production decrement, naturally. Regarding some similar researches around the world, the use of direct current electrical exposure was proven to increase number of heavy crude oil production. At least salinity, hydrocarbon chemical compounds and crude oil flow in the reservoir (electro-osmosis) involves during chemical processes in the reservoir while ESOR application. Number of electrons conducted from direct current electrical power supply will be a supporting media during chemical process of these parameters. Unfortunately after completing ESOR application in Lapangan X, the result was contradictive with this research hypothesis. Exposure of direct current electrical supply did not increased heavy crude oil production. On a contrary, parameter of salinity and API gravity as produced heavy crude oil quality, were improving significantly.
