RESILIENT CITIES AGENDA FOR THE 21st CENTURY

The Earth’s global warming and its multiple negative effects is at present the main concern of mankind. After more than 40 years of fruitless negotiations, on April 22, 2016, a record 171 countries signed a historic agreement to control the emission of Green House Gases (GHGs). The global warming has the worst impact on the biosphere and on the human and asset concentration in cities. The resilient cities initiative (RCI) is ongoing worldwide, and includes a large number of important cities, such as New York, Paris, and Melbourne. But cities located in seismic regions, such as Tokyo, Los Angeles, Santiago de Chile and Lima are adequately including disasters of geological origin, such as earthquake and tsunamis, considered in the multihazard map, base for planning safe cities. It is under this view that Peru’s Sustainable City Programme 1998-2015 is presented. At the end of 1998, when it was necessary to reconstruct the northwest cities of Peru that had been severely affected by El Niño 1997-98, it was found that the inundation maps of El Niño 1997-98 were carbon copies of the El Niño 1982-83. This was the best argument to convince the then Peruvian Prime Minister and at the same time Head of the El Niño Reconstruction CommitteeCEREN, as well as the local authorities of the affected cities that the reconstruction of the cities needed to be done based on multihazard maps, which include flooding by El Niño and earthquake effects. From 1998 to 2015, the multihazard map, land-use plan to reduce disasters plus four to eight disasters mitigation profiles were produced for 175 Peruvian cities, that have received important national and international recognition. Early 2015, it was considered that it was the right time to initiate the adaptation of the Peru Sustainable City Programme to Resilient Cities Initiative (RCI). As a case study of adaptation, the city of Sullana has been selected. Lima, the capital city of Peru with 2,819 km, and a population of 9.45 million people, has a number of disaster reduction investigations. At the same time, to consolidate those studies, the resilient cities initiative model is being applied in the city planning of future Lima. Up to now, the Sustainable City Programme in Peru was focused on the physical safety of cities, considering disasters of geological mainly earthquakes and tsunamis and climatic origin, but now social and economic issues are being included to reduce stress in the residents of the Metropolitan Lima Region. In September 2016 in a working meeting with the mayor of Lima, he decided that general manager of Lima impulse the Lima Resilient Programme.
A topic-based sentence representation for extractive text summarization

In this study, we examine the effect of probabilistic topic model-based word representations, on sentence-based extractive summarization. We formulate the task of summary extraction as a binary classification problem, and we test a variety of machine learning algorithms, exploring a range of different settings. An wide experimental evaluation on the MultiLing 2015 MSS dataset illustrates that topic-based representations can prove beneficial to the extractive summarization process in terms of F1, ROUGE-L and ROUGE-W scores, compared to a TF-IDF baseline, with QDA-based analysis providing the best results.
A Comparative Study of Single Phase Grid Connected Phase Looked Loop Algorithms

A Phase-Locked Loop (PLL) is a vital part of power inverters for achieving synchronization with the utility grid. Throughout the phase angle of the grid voltage, a reference signal is generated in order to synchronize the operation condition of the renewable energy generation systems with the utility grid. The present paper presents a comparative study of the enhancement for conventional phase-locked loop using four different filters, including adaptive notch filter, second order adaptive notch filter, generalized integrator filter and second order generalized integrator filter. A comparison among these four studied improvements was conducted under normal operation condition. On the other hand, the performance of these filters was tested under two abnormal scenarios; voltage sag and phase jump. The results showed that the second order generalized integrator based PLL has superior performance over the other filters based PLL under both normal and fault operation conditions. In contrast, the adaptive notch based filter based PLL has the lowest response under both operation conditions. © 2017 Jordan Journal of Mechanical and Industrial Engineering. All rights reserved
Destruction of measurement scale through exploratory factor analysis in production and operations research

Resumo: O presente artigo teve como objetivo avaliar o uso da análise fatorial exploratória (AFE) nas pesquisas da área de Produção e Operações, discutindo a adequação de sua utilização. Foram analisados 97 artigos (61 internacionais e 36 nacionais), totalizando 140 aplicações da análise fatorial (AF), no período de 2010 a 2015. Verificou-se que, nos artigos internacionais, predomina o uso de técnicas confirmatórias e a aplicação da AFE para se avaliar o common method bias, ao passo que, nos artigos nacionais, a técnica foi utilizada com funções mais tradicionais, como, por exemplo, a avaliação da unidimensionalidade ou ainda a geração escores, para uso em outras técnicas. Apesar de os livros didáticos para o ensino de AFE focarem, exclusivamente, no uso da AFE de modo exploratório (identificar a quantidade e o significado dos fatores comuns), este uso tem sido o menos frequente nos artigos publicados, tanto nacionais como internacionais. Apurou-se, ainda, que, em quatro artigos nacionais, houve “destruição de teoria” ao se usar AFE, quando deveria ter sido utilizada a AF confirmatória. Estes resultados indicam que as pesquisas nacionais têm feito uso questionável da técnica, o que sugere a necessidade de discussão desse tema entre os acadêmicos, de forma a se difundirem as boas práticas. Palavras-chave: Análise multivariada de dados; Métodos e modelos estatísticos; Análise fatorial exploratória; Análise fatorial confirmatória; Escalas de mensuração em produção e operações. Abstract: This paper aims to assess the use of Exploratory Factor Analysis by Production and Operations researchers, discussing the adequacy of its application. We analyzed 97 papers published between 2010 and 2015 in the Production and Operations area -of which 61 and 36 were published in international and Brazilian journals, respectively. These papers contain 140 different applications of Factor Analysis. The research shows that confirmatory techniques are prevalent in international papers, as well as exploratory techniques to evaluate the problem of common method bias. Conversely, the papers in Brazilian journals typically use the exploratory technique in more traditional ways, such as to confirm the unidimensionality of the construct, or still to generate scores for use in other statistical techniques. Despite the textbooks for the AFE teaching focus exclusively on the use of AFE in the exploratory mode (to identify the number and meaning of the common factors), this use has been less frequent in published articles, both national and international. Moreover, the research shows that the inappropriate use of exploratory (rather than confirmatory) factor analysis in four Brazilian papers resulted in the “destruction of theory”. These findings suggest that national research have been using exploratory factor analysis in a questionable way; in this sense we propose scholars discuss this topic in order to disseminate the good practices.
Multi-lingual Wikipedia Summarization and Title Generation On Low Resource Corpus

MultiLing 2019 Headline Generation Task on Wikipedia Corpus raised a critical and practical problem: multilingual task on low resource corpus. In this paper we proposed QDAS extractive summarization model enhanced by sentence2vec and try to apply transfer learning based on large multilingual pre-trained language model for Wikipedia Headline Generation task. We treat it as sequence labeling task and develop two schemes to handle with it. Experimental results have shown that large pre-trained model can effectively utilize learned knowledge to extract certain phrase using low resource supervised data.
Word Recovery in Word-Lost Documents Using an Artificial Intelligence Methodology

Documents are often physically damaged in part. Even if you save a damaged document online, it will be hard to recover it. Therefore, this study aims to develop an artificial intelligence methodology that can guess and recover lost words in documents. This study demonstrates that the Skip-Gram model can be used to construct relationships between words using the word embedding technique, a simplified form of the neural network language model. It also shows that the relationship between words can be used to infer words to fit in a specific part of a lost document.
Moderating Effect of Gender

Background and ObjectiveaaWaketime procrastination (WP) is a behavior involving delaying getting out of bed in the morning despite being awake. Previous studies have noted a relationship between WP and depression, but there have been a lack of empirical studies investigating this relationship. This study aimed to examine the moderating effect of gender in the relationship between depression and WP in insomnia patients. MethodsaaParticipants consisted of 78 adults (men = 52.6%, women = 47.4%), who met DSM-5 diagnostic criteria for insomnia disorder. All participants completed the Korean version of Center for Epidemiologic Studies Depression Scale-Revised (K-CESD-R) and sleep diaries for a week. WP behavior was calculated based on sleep diary data using the difference in time between wake time and time out of bed. Weekday and weekend sleep diary data were analyzed separately, as many individuals display different sleep behaviors on the weekend compared to the weekdays. ResultsaaResults indicated a significant positive relationship between WP and depression (r = 0.335, p < 0.01). Gender moderated the relationship between depression and WP on both weekdays and weekends [B = -1.239, 95% confidence interval (CI) = -2.092, -0.386 and B = 2.136, 95% CI = 0.643, 3.630, respectively]. Men with high depression showed more WP on weekdays, while women with high depression showed more WP on weekends. ConclusionsaaWP may be an important behavior to consider in the clinical context of providing sleep treatment for individuals who are depressed, especially when considering gender differences.

A Bipolar Reference Based BCI

Portable brain-computer interfaces (BCIs) have become a hot topic. An easily worn system is preferred, which means not too much channels are needed in the system. Here, bipolar reference (BPR) is applied to calculate features of motor imagery in electroencephalogram (EEG). This method just uses a few channels of signals. It reflects both amplitude and phase information in EEG. In this paper, fisher linear discriminant analysis (FLDA) is used as the classification method. Recognition accuracies of using BP method and common spatial pattern (CSP) filtering method with different numbers of channels are given. Variance analysis for the classification rates have shown that BP method performed well as CSP when using only a few channels.
Time-resolved Tomographic-PIV measurement in the near-wall region of a turbulent boundary layer

The flow in the near-wall region in the turbulent boundary layer has been measured by time-resolved Tomographic-PIV. The resulting instantaneous three-dimensional velocity fields allow visualizing the flow structure in buffer layer or log layer with sufficient spatial resolution of 16×16×16 wall units in a volume spanning 680×170×620 wall units in the streamwise-, wall normaland spanwise direction respectively. At the measurement location, the thickness of turbulent boundary layer is 71 mm. This corresponds to the Reynolds number based on momentum thickness of 2030. Instantaneous results show the regions of vortical motion detected using the Q-criterion and lowspeed streaks. The distance between low-speed streaks observed in the present experiments is about 100 wall units, which is consistent with earlier experimental studies or numerical studies. In addition, we can visualize vortical motion, such as streamwise vortices, and the autogeneration of a hairpin-like structure. Moreover, the measurement volume extends into the log layer, which enables us to study the effect of the large-scale motions in the log layer passing over the near-wall structures.
The Causal Effect of Deficiency at English on Female Immigrants’ Labor Market Outcomes in the UK

The Causal Effect of Deficiency at English on Female Immigrants’ Labor Market Outcomes in the UK We investigate the extent to which deficiency at English as measured by English as Additional Language (EAL), contribute to the immigrant-native wage gap for female employees in the UK, controlling for covariates. To deal with the endogeneity of EAL and a substantial problem of self-selection into employment we suggest a 3-step estimator (TSE). The properties of this estimator are investigated in a Monte Carlo simulation study and we show evidence that TSE delivers a consistent and asymptotically normal estimator. We find a large and statistically significant causal effect of EAL on the immigrant-native wage gap for women. NON-TECHNICAL SUMMARY Using the first wave of the UK Household Longitudinal Survey, we investigate the extent to which deficiency at English as measured by English as Additional Language (EAL), contribute to the immigrant-native wage gap for female employees in the UK, after controlling for age, region of residence, educational attainment and ethnicity. To deal with the potential endogeneity of EAL and a substantial problem of self-selection into employment we suggest an easy to implement 3-step estimation (TSE) procedure. The properties of the TSE estimator are investigated in a Monte Carlo simulation study and we show evidence that our procedure delivers a consistent and asymptotically normal estimator. We find that English as Additional Language (EAL) has a causal effect of -25% on wages for UK female immigrants and that the adjusted immigrant-native wage gap is fully accounted by EAL.

Projection and Bias . A Simulation Study ⇤

The Downsian proximity and the Rabinowitz/Macdonald directional model of voting assume that relations between voters and parties in a political space matter for vote choice. The proximity camp tends to favor subjective, voter-specific party placements, while the directional camp favors “objective”, unified party placements. Overall, supporters of directional voting are concerned that voter-specific party placements may be biased due to projection effects. This implies that individuals, for whatever reason, may locate parties they like closer to their personal ideal point (assimilation), while pushing parties they oppose further away (contrast). This paper provides two specific contributions: First, building on data from the European Election Studies series, we demonstrate that projection effects are both statistically significant and substantively meaningful. Our analysis introduces a novel measurement model that is suitable for the analysis of multiparty competition and reveals that, contrary to the published record, contrast effects are larger than assimilation effects. Secondly, we show that projection effects effectively bias empirical assessments of proximity and directional voting. We apply counterfactual simulation studies to illustrate that individual-specific party placements with a real-world magnitude of projection effects do indeed favor empirical estimates of proximity over directional voting. ⇤Paper prepared for the EPOP 2014 Conference, University of Edinburgh, 12-14 September 2014
WEALTH CREATION BY M&A ACTIVITIES

This paper examines the value implications of mergers and acquisitions (M&A) conducted worldwide within the luxury goods industry over the period from 1993 to September 2005. The luxury goods industry embraces a few number of companies located in many different countries and largely operating internationally. This event study analysis with the intent of measuring the value created by luxury M&As includes 196 transactions over the last 13 years. Both market and risk adjustment reveal positive announcement effects and consequently can be interpreted as value creating. However, risk adjustment leads to conspicuously reduced and less statistically significant excess returns than market adjustment. The characteristics of both the industry per se and the sample considered require a very critical assessment of the results with regard to the respective methodology applied.

Methodological Issues in the Analysis of Health-Related Quality of Life Data for Cost-Effectiveness Analysis

Health economic evaluations, developed for the purposes of informing technology adoption decisions in publicly-funded health care systems, should strive to make use of all relevant evidence. Any failure to meet this objective will result in a partial representation of the evidence base and, consequently, there is a potential risk of obtaining misleading results. Unfortunately, a lack of comparability amongst the alternative measures of health-related quality of life (HRQoL) complicates the synthesis of this type of evidence. One solution to this problem is to specify a reference case measurement to promote comparability, although this may provide an incomplete representation of HRQoL effects or, in some cases, no evidence at all. The application of mapping functions - statistical algorithms that link HRQoL measures - might provide a means to incorporate a broader range of heterogeneous outcome measures for evidence synthesis. One method in particular, known as the common factor model (CFM), has been proposed in this regard due to its coherent mapping properties. Research involving the CFM has been conceptual to date and only a handful of case studies have ever been conducted. However, this method can be formulated as a structural equation model (SEM), an approach that has benefited from extensive application in other areas of research. The primary aim of this thesis is to investigate the plausibility of SEM methods serving as a generalised framework for the handling of HRQoL evidence. SEM methods are tested across scenarios involving aggregate data, individual patient data and a combination of both; in each case, a comprehensive synthesis of heterogeneous HRQoL outcomes using the SEM approach is compared against a restrictive synthesis involving a reference case measurement. In addition, the implications of these alternative approaches are explored from a decision-making viewpoint.
Numerical Simulation of Currents and Volume Transport in the Malacca Strait and Part of South China Sea

This work aimed to determine the hydrodynamics of the Malacca Strait (MS) and the part of the South China Sea (SCS). The study uses the two-dimensional numerical model with a finite-difference method. The results show that the sea surface heights in MS and the part of SCS are reversed and consistent with assimilation data that derived from Simple Ocean Data Assimilation (SODA). Sea surface in northern MS is lower than that in the southern part during January and July. However, the interval of SSH in both January and July appears differently. It is steeper in January than in July. Therefore, the currents and transports during January are stronger than those during July. However, the direction of currents and volume transport of MS flow to the Andaman Sea both in January and July. In part of SCS, the pattern is relatively the same as in MS; that is, the currents during January are stronger than those during July. In general, mostly volume transport in MS is going to the Andaman Sea and volume transport from part of SCS is deflected to the southern part of MS, especially in January.
Vitamin D Status Across Age Groups in Turkey: Results of 108742 Samples from a Private Laboratory Short title: Vitamin D Status in Turkey

Objective: This population-based study aimed to determine the vitamin D status in Turkey between 2011 and 2016, evaluate the effectiveness of the national vitamin D supplementation program. Methods: Data on serum 25-hydroxyvitamin D (25-OHD) measurements were retrieved from an internationally accredited laboratory operating nationwide. A total of 108,742 measurements of 25-OHD were analyzed using the cut-off values of 011 ng/ml, 12-19 ng/ml, 20-49 ng/ml, 50-70 ng/ml and >70 ng/ml. Results: Overall, the mean 25-OHD level was 21.6±13.3 ng/ml. The mean 25-OHD levels according to age brackets were as follows: 37.3 ng/ml for <1 year of age, 30.1 ng/ml for 1-10 years of age, 23.7 ng/ml for 11-18 years of age. The mean 25OHD levels among children <1 year and 1-3 years of age were significantly higher compared with those found for the other age groups. The prevalence of vitamin D deficiency (<12 ng/ml) was lowest in children at 1-3 years of age (5%). Conclusion: With successful implementation of the vitamin D supplementation program, Turkey seems to have overcome vitamin D deficiency for those under 1-years of age. However, the positive impact of the program does not continue over 1 year of age, indicating that vitamin D supplementation may be required in the older children and adults. On the other hand, increased awareness about vitamin D should be continued to prevent unnecessary and excessive use of vitamin D supplements.
Reducing Checkpoint Creation Overhead using Data Similarity

Checkpoint/restart is a common technique deployed in the high-performance computing (HPC) systems to provide a fault-tolerant capability. The most widely deployed implementation of MessagePassing Interface (MPI) standard called MPICH adopted Berkeley Lab Checkpoint/Restart (BLCR) library for its checkpoint creation. Unfortunately, the checkpoint size grows rapidly as the number of processes increases. This paper proposes an efficient checkpoint creation technique for MPI-based HPC applications. The proposed technique uses a Pin-based binary instrumentation tool to perform sub-routine probing and memory write tracking to gather information pertinent to the reduction of checkpoint sizes during the normal execution time. The experiments on five HPC applications from the NAS Parallel Benchmarks using medium problem sizes (Class B) yielded the results showing a reduction of checkpoint size ranging from 9.9% to 49%.
