Evaluation of the biochemical composition of tropical red seaweeds Galaxaura rugosa and Gelidiella acerosa from Ujung Genteng waters, Indonesia

Galaxaura rugosa and Gelidiella acerosa, two selected Indonesian red seaweeds were analyzed to determine their proximate composition, amino acid and fatty acid contents. The objective of this study was to evaluate the various nutritional parameters of G. rugosa and G. acerosa for utilization in human nutrition Proximate composition, including moisture, ash, protein, fat and carbohydrate were determined according to AOAC standard methods. Amino acid was determined by Ultra Performance Liquid Chromatography (UPLC) and fatty acid by gas chromatography. Ash and carbohydrate contents were the two most abundant components in these seaweeds. The ash content of G. rugosa and G. acerosa were 72.97% and 13.42%, while carbohydrate content were 16.91% and 68.67% based on dry weight, respectively. Both seaweeds contained significantly higher amounts of protein where G. rugosa and G. acerosa were found to be 5.34% and 8.66% based on dry weight, respectively. While moisture and fat contents were relatively low. The moisture content of G. rugosa and G. acerosa were 4.25% and 8.71%, while fat content were 0.53% and 0.54% based on dry weight, respectively. Total 14 amino acids were identified where glutamic acid was the major constituent in both species. In the case of fatty acids, 8 components were identified in G. rugosa and 7 components identified in G. acerosa. Lauric acid was the major constituent in the both species followed by palmitic acid. G. rugosa and G. acerosa contained 0.21%, 0.20% lauric acid and 0.10%, 0.14% palmitic acid respectively. Based on the above, this present study results showed that G. rugosa and G. acerosa from Ujung Genteng waters could be utilized as functional ingredient for the valuable nutritional properties for food supplement industries in the future.
Mutual Fund Styles and Clientele-Specific Performance Evaluation

This paper develops clientele-specific performance measures based on the style preferences of mutual fund investors. Proposing an approach that considers investor disagreement and exploits style classification data, we investigate eight measures to represent investors with favorable preferences for size and value equity styles using a large sample of actively-managed U.S. equity mutual funds from 1998 to 2012. We find that the implied style preferences differ in their rational and behavioral features- value and small-cap fund investors (growth and large-cap fund investors) are more (less) averse to difficult economic conditions, and tend to be pessimists and contrarians (optimists and trend followers). The performance of funds assigned to clientele-specific styles becomes neutral or positive when evaluated with measures that consider their most likely style clienteles. The sign of the value added by the industry is ambiguous and depends on the choice of measures. Hence, performance is more favorable when funds are evaluated with their appropriate style-clientele-specific measure, and can otherwise depend on the measure.
de Travail n ° 2019-16 Inattention and the Taxation Bias

This paper studies how information frictions in agents’ tax perceptions affect the design of actual tax policy. Developing a positive theory of tax policy, we show that agents’ inattention interacts with policymaking and induces the government to implement inefficiently high tax rates: this is the taxation bias. We quantify the magnitude of this policy distortion for the US economy. Overall, our findings suggest that existing information frictions – and thereby tax complexity – lead to undesirable, large and regressive tax increases.
Hydrographic responses to regional covariates across the Kara Sea

The Kara Sea is a shelf sea in the Arctic Ocean which has a strong spatiotemporal hydrographic variation driven by river discharge, air pressure, and sea ice. There is a lack of information about the effects of environmental variables on surface hydrography in different regions of the Kara Sea. We use a hierarchical spatially varying coefficient model to study the variation of sea surface temperature (SST) and salinity (SSS) in the Kara Sea between years 1980 and 2000. The model allows us to study the effects of climatic (Arctic oscillation index (AO)) and seasonal (river discharge and ice concentration) environmental covariates on hydrography. The hydrographic responses to covariates vary considerably between different regions of the Kara Sea. River discharge decreases SSS in the shallow shelf area and has a neutral effect in the northern Kara Sea. The responses of SST and SSS to AO show the effects of different wind and air pressure conditions on water circulation and hence on hydrography. Ice concentration has a constant effect across the Kara Sea. We estimated the average SST and SSS in the Kara Sea in 1980–2000. The average August SST over the Kara Sea in 1995–2000 was higher than the respective average in 1980–1984 with 99.9% probability and August SSS decreased with 77% probability between these time periods. We found a support that the winter season AO has an impact on the summer season hydrography, and temporal trends may be related to the varying level of winter season AO index.
Offensive Comments in the Brazilian Web: a dataset and baseline results

Brazilian Web users are among the most active in social networks and very keen on interacting with others. Offensive comments, known as hate speech , have been plaguing online media and originating a number of law-suits against companies which publish Web content. Given the massive number of user generated text published on a daily basis, manually ﬁltering offensive comments becomes infeasible. The identiﬁcation of offensive comments can be treated as a supervised classiﬁcation task. In order to obtain a model to classify comments, an annotated dataset containing positive and negative examples is necessary. The lack of such a dataset in Portuguese, limits the development of detection approaches for this language. In this paper, we describe how we created annotated datasets of offensive comments for Portuguese by collecting news comments on the Brazilian Web. In addition, we provide classiﬁcation re-sults achieved by standard classiﬁcation algorithms on these datasets which can serve as baseline for future work on this topic.
NeurIPS 2019 Disentanglement Challenge: Improved Disentanglement through Learned Aggregation of Convolutional Feature Maps

This report to our stage 2 submission to the NeurIPS 2019 disentanglement challenge presents a simple image preprocessing method for learning disentangled latent factors. We propose to train a variational autoencoder on regionally aggregated feature maps obtained from networks pretrained on the ImageNet database, utilizing the implicit inductive bias contained in those features for disentanglement. This bias can be further enhanced by explicitly fine-tuning the feature maps on auxiliary tasks useful for the challenge, such as angle, position estimation, or color classification. Our approach achieved the 2nd place in stage 2 of the challenge. Code is available at this https URL.
Analysis of Income Tax Compliance Levels among Workers in the Informal Sector in Nakuru Central Business District, Kenya

Tax compliance in the informal economy is a matter of serious concern in many developing countries, and one of the biggest challenges of Taxation in Kenya. Kenya has one of the largest informal sectors in Africa employing approximately 77.9 per cent of the working population. The sector is estimated to have the potential to contribute 67.2 Billion Shillings of taxes per year, however, the highest achieved collection has been 136 Million in financial year 2008/09 which continue to dwindle year after year. Attempts by the government to introduce the presumptive turn over tax have also been futile. Owing to the size of the sector and its continued growth, its therefore important for the government to understand ways of bringing the informal sector into the tax net. Research on the challenges of taxing the informal economy in Kenya remains blurred therefore it was the focus of this study to subject tax compliance to empirical analysis in informal sector in the Kenyan context and the factors contributing to the low compliance levels among the informal sector enterprises in Nakuru Town. The study sought to analyze the tax compliance in the informal economy in Nakuru Town, and analyse how use of i-tax platform has influenced compliance. The study was conducted in Nakuru Town CBD among the informal sector workers using the descriptive survey research design. The target population was 153,286 informal sector workers, from which a study sample of 99 was selected using simple random sampling technique. The results were then presented by means of tables and charts for ease of understanding. The study revealed that the use of i-tax has significantly improved income tax compliance among informal sector workers in Nakuru CBDβ = 0.514, p < 0.05. The study therefore recommended that the KRA should engage in intensive training to enhance the knowledge on taxation among informal sector workers and the use of oline tax platforms to ease compliance among workers in the informal sector.
Nacre characterization of pearl oysters Pinctada margaritifera from Arakan waters, North Sulawesi, Indonesia

Mother of pearl inside the pearl oyster Pinctada margaritifera was studied to provide information on the diversity of the aragonite microtablets and their biomineral compositions. This information can be used to reveal the specific characters of the nacre of the oyster from North Sulawesi coastal waters and as a basis for the oyster size selection in pearl culture. Thirty samples of oysters from Arakan waters had been prepared for their shells and then the nacre layer was analyzed using Scanning Electron Microscope and Energy Dispersive X-Ray Spectroscope. Results showed that the nacre-composing microtablets varied with shell size, with thickness of 0.36-0.90 μm. The maximum thickness was found in P. margaritifera of 80-90 mm shell length. The biomineral composition contained in the tablet is Ca>Mo>Na>Al>Mg>Se>Fe>Mn>Cr.
Experimental evaluation of a robust optimization method

Internal organ motion during radiation therapy, if not considered appropriately in the planning process, has been shown to reduce target coverage and increase the dose to healthy tissues. Standard planning approaches, which use safety margins to handle intrafractional movement of the tumor, are typically designed based on the maximum amplitude of motion, and are often overly conservative. Comparable coverage and reduced dose to healthy organs appear achievable with robust motion-adaptive treatment planning, which considers the expected probability distribution of the average target position and the uncertainty of its realization during treatment delivery. A dosimetric test of a robust optimization method for IMRT was performed, using patient breathing data. External marker motion data acquired from respiratory-gated radiotherapy patients were used to build and test the framework for robust optimization. The motion trajectories recorded during radiation treatment itself are not strictly necessary to generate the initial version of a robust treatment plan, but can be used to adapt the plan during the course of treatment. Single-field IMRT plans were optimized to deliver a uniform dose to a rectangular area. During delivery on a linear accelerator, a computer-driven motion phantom reproduced the patients’ breathing patterns and a two-dimensional ionization detector array measured the dose delivered. The dose distributions from robust-optimized plans were compared to those from standard plans, which used a margin expansion. Dosimetric tests confirmed the improved sparing of the non-target area with robust planning, which was achieved without compromising the target coverage. The maximum dose in robust plans did not exceed 110% of the prescription, while the minimum target doses were comparable in standard and robust plans. In test courses, optimized for a simplified target geometry, 0031-9155/09/092901+14$30.00 © 2009 Institute of Physics and Engineering in Medicine Printed in the UK 2901 2902 C Vrančić et al and delivered to a phantom that moved in one dimension with an average amplitude of 17 mm, the robust treatment design produced a reduction of more than 12% of the integral dose to non-target areas, compared to the standard plan using 10 mm margin expansion.

Exploring Students Perceptions and Performance in Flipped Classroom Designed with Adaptive Learning Techniques: A Study in Distributed Systems Courses

In Computer Science, teaching Distributed Systems presents many challenges primarily related to the students’ prior knowledge. Some new Learning Approaches emerged and can aid to improve learning processes in this scenario, such as Flipped Classroom and Adaptive Learning. In this context, this paper presents a study of the integration of the Flipped Classroom method with Adaptive Learning techniques for assisting Distributed Systems courses. We conducted quantitative and qualitative analysis to evaluate students’ acceptance. We also implemented a quasi-experimental study to evaluate the learning impact on students. Students had a significant improvement in the test score in both approaches.
Are investment promotion agencies doing the right thing? evidence from China

This paper tries to verify how the establishment of investment promotion agencies (IPAs) affects the decisions of foreign firms regarding their subsequent investment by combining firm-level data from the World Bank's Enterprise Survey with city-level information on (IPAs) in China. After correcting for potential endogeneity problems, the result confirms the IPAs' role in promoting incremental foreign direct investment (FDI) into China. Furthermore, it is shown that Hong Kong, Macau, and Taiwan (HMT) firms are less sensitive to IPAs' efforts in making further investment than are non-HMT foreign firms. In addition, IPAs are found to be more successful in enhancing foreign firms' investment in high-tech than in low-tech industries.
Entrepreneurial persistence beyond survival: Measurement and determinants

ABSTRACT Entrepreneurial persistence is demonstrated by an entrepreneur’s continued positive maintenance of entrepreneurial motivation and constantly renewed active engagement in a new business venture despite counterforces or enticing alternatives. It thus is a crucial factor for entrepreneurs when pursuing and exploiting their business opportunities and in realizing potential economic gains and benefits. Using rich data on a representative sample of German business founders, we investigated the determinants of entrepreneurial persistence. Next to observed survival, we also constructed a hybrid persistence measure capturing the motivational dimension of persistence. We analyzed the influence of individual-level (human capital and personality) and business-related characteristics on both measures as well as their relative importance. We found that the two indicators emphasize different aspects of persistence. For the survival indicator, the predictive power was concentrated in business characteristics and human capital, while for hybrid persistence the dominant factors were business characteristics and personality. Finally, we showed that results were heterogeneous across subgroups. In particular, formerly unemployed founders did not differ in survival chances, but they were more likely to lack a high psychological commitment to their business ventures.
Managing pre-eclampsia and eclampsia in Dar es Salaam public health facilities: A focus on equipment, supplies, drugs and knowledge of healthcare workers

Introduction: Severe pre-eclampsia and eclampsia (PE/E) is associated with high maternal and neonatal morbidity and mortality. Early detection and treatment of pre-eclampsia may prevent progression to severe PE/E. When severe PE/E occurs, timely use of anticonvulsants and antihypertensives (as part of emergency obstetric and neonatal care) are needed to reduce morbidity and mortality. This study is aimed at assessing the capacity in managing PE/E in public health facilities in Dar-es-Salaam, Tanzania. Methods: A descriptive cross-sectional study was conducted in selected public health facilities in Dar-es-Salaam city that offer reproductive and child services. The health facilities included four hospitals, three health centres and 23 dispensaries. A checklist was used to assess availability of equipment, supplies and drugs, and a structured questionnaire administered by an interviewer was used to assess healthcare workers’ knowledge on risks, symptoms, and drugs used to manage for PE/E. The results are presented as proportions. Results: Guidelines for management of PE/E were available in all hospitals and health centres while 39% of the dispensaries had no the guidelines. Functioning blood pressure machines and stethoscopes were available in all facilities but urine test strips for detecting protein in the urine were available in only one hospital (25%) and 9 (39%) dispensaries. Anticonvulsant drugs were available in all health facilities. Magnesium sulphate, the first-line recommended anticonvulsant, was available in only a quarter of the dispensaries. A quarter of the dispensaries had nifedipine or methyldopa available as antihypertensives, with availability for both drugs being 75% and 100% in the hospitals and health centres respectively. The antihypertensive hydralazine was available in 50%, 33% and 8% of the hospitals, health centres and dispensaries respectively. Calcium gluconate was available in one hospital and one health centre only. Healthcare workers were knowledgeable regarding most risk factors, symptoms and drugs for treatment of hypertension and convulsions in PE/E. A higher proportion of doctors were knowledgeable of the risk factors, symptoms and drugs than the nurses and clinical officers. The majority of the healthcare workers mentioned magnesium sulphate as the drug for treatment of convulsions in PE/E. Conclusions: There is insufficient screening and management of PE/E due to lack of equipment, supplies and drugs. Healthcare workers are relatively knowledgeable regarding risk factors, symptoms and drugs for managing PE/E. This calls for an increase in availability of equipment, supplies and drugs for managing women with PE/E. Healthcare workers need to receive ongoing education to sustain quality care for women with PE/E. Keywords: Pre-eclampsia; Eclampsia; Equipment and supplies; Drugs; Knowledge
Household Portfolios and Financial Preparedness for Retirement

Using a lifecycle model of consumption, saving and portfolio choice combined with linked survey and administrative data on wealth and lifetime earnings we evaluate measures of retirement preparedness. We estimate heterogeneous discount factors for households and compare these estimates of their patience to their replacement rates—the simple measure often used to evaluate the adequacy of retirement savings. We find first that the specification of the model's asset structure matters quantitatively for preference parameter estimates—households appear to be much more patient when they are assumed to have access only to a risk‐free asset compared to when we account for the fact that much of their wealth is stored in higher‐return tax‐advantaged private pensions and in housing. Second, we find that only the most patient households achieve the replacement rates out of final earnings that are often recommended by policymakers and industry as sensible benchmarks for retirement preparedness. Notwithstanding this, we find that even quite impatient households in the population we study achieve high replacement rates out of lifetime average income—a more sensible summary measure of preparedness for retirement.

Quantifying migration cost shocks: Macroeconomic evidence for the UK and Germany

EU net immigration into the UK decreased by almost 40 percent since the introduction of a net immigration target and the Brexit vote. In Germany EU immigration reached unprecedented high numbers that mirror the good labor market conditions. However, migration diversion might have played a key role, too, since the Brexit vote has raised immigration costs immediately by increasing the uncertainty about the future status of immigrants. In the paper we study to what extent the German labor market benefited from worsening immigration prospects in the UK by disentangling the effects of higher immigration cost in the UK and favorable labor market conditions in Germany on migrants’ destination choice. To that end we build a two-country DSGE model of immigration for the UK and Germany. We estimate the model using quarterly bilateral migration data for different geographic regions. We are able to separate two different types of migration shocks: One that is corridor-specific and one that increases migration into the whole corridor. This allows us to study the counterfactual scenario of immigration to Germany in the absence of the British vote to leave the EU. In Germany migration diversion explains 5 percent of additional net migration, in UK it can account for around 10 percent of the migration drop.
The Relationship between Service Quality and Revisit intention: Based on self-service retail technology

This paper is focused on how firms increase customers’ acceptance of self-service retail, and impact of self-efficacy on effective customer experience, customer satisfaction and loyalty. This paper mainly uses questionnaires to conduct empirical research on collecting 308 used selfservice convenience stores from China. The study employs a structural equation model to analyze relationship between service quality and revisit intention, Word of mouth. The results shown that service perceived quality significantly influences customer satisfaction. Also, self-service retail service quality and experience values are two important elements for consumers to accept self-service retail stores. Additionally, the relationship between consumer experience value and satisfaction, loyalty, and selfservice retail stores has a significant impact on Perceived self-efficacy.
N ov 2 01 9 A NOTE ON THE NUMBER OF IRRATIONAL ODD ZETA VALUES

By modifying the auxiliary rational functions of Fischler, Sprang and Zudilin in [3], we prove that, for all odd integer s ≥ 10, there are at least 1 10 s (log s)1/2 irrational numbers among the following odd zeta values: ζ(3), ζ(5), ζ(7), · · · , ζ(s). This improves the lower bound 2 (1−ε) log s log log s in [3].
Employment Cyclicality by Firm Size, Wage, and Productivity in Brazil

We provide evidence on whether job flows reallocate workers from low productivity to high productivity firms using for the first time a direct productivity measure. We constructed a monthly linked employer-employee dataset for Brazil and argue for the use of a direct productivity measure to analyze the firm productivity job ladder as often used productivity proxies, such as employment size and wages, are weakly related to productivity. When total factor productivity is used to rank firms, results suggest that workers move up the productivity ladder by moving from young firms with low productivity to old firms with high productivity.
