Comparative Study of Record Linkage Approaches for Big Data

Record linkage is a challenging task for Big Data. This paper, hence, attempts to shed light on record linkage approaches for Big Data by comparing three dimensions involving record linkage phases, dataset properties, and parallel processing approach for Big Data. The current state of art have only conducted comparative studies between record linkage approaches. There has been only one comparative study exploring the whole record linkage framework of the relational database. It is believed that the focus of the present study on the dimensions of the parallel processing approaches for Big Data and dataset properties was worth exploring. It was found that first, data exploration was almost a non-existing phase despite its importance of exploring the dataset being examined; second, techniques that handle data standardization and preparation phase of the first dimension were not extensively covered in the literature which can directly affect the results’ quality; third, the record linkage in unstructured data was not yet explored in literature; fourth, the MapReduce was used in about 50 % of the selected studies to handle the parallel processing of Big Data, but due to its limitations, more recent and efficient approaches had been used, such as Apache Spark and Apache Flink. Apache Spark is just recently adapted to resolve duplicates due to its supporting of in-memory computation, which makes the whole linkage process more efficient. Although the comparative study includes many recent studies supporting Apache Spark, adopting Apache Spark to solve the problem of record linkage is not yet well explored in literature, as more researches need to be conducted. In addition, Apache Flink is still rarely used to solve the record linkage problem of Big Data. Fifth, pruning techniques, used to eliminate unnecessary comparisons, are not adequately applied in the covered studies despite their effect on reducing the search space resulting in a more effective Record Linkage process.
Will ‘we’ continue to exercise? The associations between group identification, identity leadership, and relational identification on group exercise class adherence

The present study sought to provide support for the roles of both the social identity approach (group identification and identity leadership) and relational identification in adherence to group exercise classes. One hundred and twenty U.K. based group exercise class attendees completed an online survey in a cross-sectional design. Group identification, perceptions of identity leadership behaviour, and relational identification were not significantly associated with length of class attendance. However, both identity leadership behaviour of the class instructor and ingroup affect (measured as an element of multi-dimensional group identification), were significantly associated with expected likelihood of continued class participation. For every 1 unit increase in the identity leadership and in-group affect measures respectively, participants were 1.9 and 2.0 times more likely to be ‘at or near 100%’ likely to continue vs not. Social identity variables were not associated with how long exercisers had been attending class, but identity leadership and ingroup affect are positive influencers of expected future adherence. Further research into the social identity approach and identity leadership behaviour regards exercise class attendance tenure vs volume is warranted and is likely to benefit from the use of multi-dimensional group identification measures.
Follow the Leader: Technical and Inspirational Leadership in Open Source Software

We conduct the first comprehensive study of the behavioral factors which predict leader emergence within open source software (OSS) virtual teams. We leverage the full history of developers’ interactions with their teammates and projects at github.com between January 2010 and April 2017 (representing about 133 million interactions) to establish that – contrary to a common narrative describing open source as a pure “technical meritocracy” – developers’ communication abilities and community building skills are significant predictors of whether they emerge as team leaders. Inspirational communication therefore appears as central to the process of leader emergence in virtual teams, even in a setting like OSS, where technical contributions have often been conceptualized as the sole pathway to gaining community recognition. Those results should be of interest to researchers and practitioners theorizing about OSS in particular and, more generally, leadership in geographically dispersed virtual teams, as well as to online community managers.
Scheduling with position-dependent weights, due-date assignment and past-sequence-dependent setup times

In this study, we consider single-machine scheduling problems with past-sequence-dependent (denoted by psd) setup times in which the setup times of jobs are proportional to the length of already processed jobs. Under common (CON) and slack (SLK) due-date assignment methods, we prove that the weighted sum of earliness, tardiness and due-date minimization remains polynomially solvable. We also give some extensions for the scheduling problems with psd setup times.
52. Western Black Sea continental slope: continuous Late Pleniglacial to Subatlantic palaeovegetation record

The Black Sea is an intercontinental enclosed-type marine basin. The Black Sea continental slope is characterised by deeply indented relief. The AKAD09-10 core studied consists of continuous deposits and was taken from the interfluvial zone located between submarine valleys. The natural vegetation of the western Black Sea coast is dominated by temperate forest communities of Quercus cerris L. and Q. frainetto Ten. , together with Q. polycarpa Schur. and Carpinus betulus L. (Bondev 1991; FilipovaMarinova et al. 2017). Riverine flooded (riparian) forests are mainly composed of Fraxinus oxycarpa Willd. , Ulmus minor Mill. , Carpinus betulus, Q. pedunculiflora C. -Koch, Alnus glutinosa (L.) Gaerth. , and Hedera helix L. Relic South-Euxinian forests of Fagus orientalis Lipsky, with the undergrowth of Rhododendron ponticum L. are spread in humid ravines of the Strandzha Mountains. Steppe vegetation of the Dobrudzha region is dominated by Festuca pseudovina Hack. ex Wiseb. , Chrysopogon gryllus (L.) Trin. , Botriochloa ischaemum (L.) Keng, and Poa bulbosa L. Elements of the Mediterranean vegetation are Paliurus spina-christi Mill. , Carpinus orientalis Mill. , Phillyrea latifolia L. , and Fraxinus ornus L. The western Black Sea coast is part of the Continental-Mediterranean climatic area and is influenced by the proximity of the sea. Mean annual precipitation in Varna is 480 mm. The mean annual temperature in Varna is 12 °C (Kotsev & Filipova-Marinova 2017).
Overview of the studies on authentication of gelatin using Fourier Transform Infrared spectroscopy coupled with chemometrics

Background and objective: In recent years, global market of halal products has been greatly developed. Sign of "Halal" on foods’ label refers to their appropriateness for Muslim and Jewish buyers, which are banned from consumption of non-halal products such as porcine derived gelatin. Pig derivatives are marketed frequently in the world because they are relatively cheap and available. Therefore, development of simple and fast methods for authentication of halal foods and raw materials has been required. At this review, we studied one of common authentication approaches for qualification of gelatin by Fourier transform infrared spectroscopy (FT-IR). Results and conclusion: Several analytical methods were conducted for evaluation of gelatin in foods. Among them, FT-IR was relatively interested because it is a simple, fast and reliable method and does not require complicated sample preparation. In some cases, it was superior to the molecular method of polymerase chain reactions (PCR) in detection of gelatin’s origin by least analytical uncertainties. Although, analysis of FT-IR results by modeling approaches such as chemometrics classification increases effectiveness of the developed method. In this review, we will show that FT-IR can be used routinely as alternative or complementary method to identify the source of gelatin with high precision.
Sensor System: A Survey of Sensor Type, Ad Hoc Network Topology and Energy Harvesting Techniques

People nowadays are entering an era of rapid evolution due to the generation of massive amounts of data. Such information is produced with an enormous contribution from the use of billions of sensing devices equipped with in situ signal processing and communication capabilities which form wireless sensor networks (WSNs). As the number of small devices connected to the Internet is higher than 50 billion, the Internet of Things (IoT) devices focus on sensing accuracy, communication efficiency, and low power consumption because IoT device deployment is mainly for correct information acquisition, remote node accessing, and longer-term operation with lower battery changing requirements. Thus, recently, there have been rich activities for original research in these domains. Various sensors used by processing devices can be heterogeneous or homogeneous. Since the devices are primarily expected to operate independently in an autonomous manner, the abilities of connection, communication, and ambient energy scavenging play significant roles, especially in a large-scale deployment. This paper classifies wireless sensor nodes into two major categories based the types of the sensor array (heterogeneous/homogeneous). It also emphasizes on the utilization of ad hoc networking and energy harvesting mechanisms as a fundamental cornerstone to building a self-governing, sustainable, and perpetually-operated sensor system. We review systems representative of each category and depict trends in system development.
GLIMPSE STUDY: IMPACT OF TRIPLE THERAPY ON LUNG FUNCTION, HEALTH STATUS, AND MORTALITY RISK IN PATIENTS WITH ADVANCED CHRONIC OBSTRUCTIVE PULMONARY DISEASE

Objectives: The objectives of the study were to estimate the relative impact of triple therapy on lung function, health status, and mortality risk compared with combination inhaled corticosteroid (ICS)/long-acting β-agonist (LABA) therapy in symptomatic chronic obstructive pulmonary disease (COPD) patients with frequent exacerbations in an Indian clinical population. Methodology: The GLIMPSE (Lung Function, Health Status, and Mortality Risk Assessment in COPD using Triple Therapy) was as a prospective, parallel design, single-center observational study comparing 24 weeks of triple therapy (twice-daily combination of budesonide [BUD]-formoterol [FOR] [100/6 μg] and once-daily tiotropium [TIO] [9 μg]) with ICS/LABA (twice daily BUD-FOR [100/6 μg]). The primary outcome was the mean change in forced expiratory volume in the 1st s (FEV1%) predicted and COPD assessment test total score from baseline at week 24. Secondary outcomes were variation in dyspnea grade and BODE total score from baseline. Results: At week 24 in triple therapy (n=70) and ICS/LABA therapy (n=70), mean difference from baseline in FEV1% predicted were 5.40 (95% confidence interval [CI]: 1.29–9.50) and 1.90 (95% CI: –1.87–5.68) respectively, and mean difference in CAT total score from baseline was –5.10 units (95% CI: –3.49–−6.71) and –1.80 units (95% CI: –0.052–−3.548), respectively. In addition, there was a statistically significant reduction in dyspnea grading and BODE score with comparable adverse events in both groups. Conclusion: Overall, the results favored triple therapy over dual therapy in advanced symptomatic COPD patients.
Null arguments and the inverse problem

Native speakers can reconstruct null arguments from a linear string of words where they are notoriously absent. How they solve this problem remains an unsolved and largely unaddressed issue. This article argues for a unified analysis of null arguments that relies on bare sensory input. The key assumption is that antecedent recovery takes place at the syntax-semantics interface if and only if the unvalued phi-features of a lexical element cannot be valued from the information available in the sensory input. The analysis unifies the theory of finite null subject pronouns and control and furthermore interprets null argument sentences without generating phrasal null pronouns. Evidence is considered from three languages with distinct null argument profiles: English (non-pro drop), Italian (consistent pro-drop) and Finnish (partial prodrop). Finally, the model was formalized and tested by means of a computer simulation.
English language teachers’ literacy competence in literature

The study was carried out to describe English teachers’ literacy competence in English literature which had a very important role in the teaching of English language through literature to strengthen character educational values. The study applied descriptive statistics in the forms of frequencies “to describe and summarize the data. ” In reporting the data, percentages were used ( Leavy, 2017: 111 ). The respondents of the study consisted of fifteen English language teachers working for five senior high schools organizing special interest classes in languages. The techniques for collecting data were questionnaires and FGD (focus group discussion). The data were analyzed by using quantitative descriptive techniques consisting of central tendency and percentage analysis. The results of the study showed that all the teachers got between two and fourteen credits in literature from their undergraduate colleges. Their reading hours in literature after graduation did not show any regular base. This was particularly due to the fact that the portion of literature materials to be taught to the students was very limited. Thus, they thought that it was not necessitated to develop literary competence to support their teaching activities. However, all of them agreed that the teaching of literature to high school students was important and useful to improve their language skills as well as their character educational values.
Elimination of interlayer Schottky barrier in borophene/C4N4 vdW heterojunctions via Li-ion adsorption for tunneling photodiodes

The nonzero interlayer Schottky barrier leads to a compromise between photodetectivity and photoresponsivity in photodiodes based on vdW heterojunctions. Seeking for the appropriate vdW heterojunction with Ohmic contact and a high tunneling barrier is of great significance to realize highperformance photodiodes. We built borophene/C4N4 (B/C4N4) vdW heterojunctions with a reduced interlayer Schottky barrier, by combining density functional theory and non-equilibrium Green’s function. The adsorption of Li-ions can further tune its Schottky contact into n-type Ohmic contact. The electronic properties of the Li-ion-adsorbed B/C4N4 vdW heterojunction, including the separation of hole–electron pairs, the work function, as well as the effective mass of carrier, can be modulated by changing the adsorption site of Li-ions. B/C4N4/Li shows the most excellent absorbing capability of the infrared illumination and the strongest negative rectification, due to the highest interlayer tunneling barrier. The bottom surface of the C4N4 sublayer is the optimal adsorption site of Li-ions, for the potential application of B/C4N4 vdW heterojunctions in tunneling photodiodes. Our work unveils the great significance of Li-ion adsorption in modulating the interlayer Schottky and tunneling barriers in vdW heterojunctions, thus improving their device performance.
A five bus AC–DC hybrid nanogrid system for PV based modern buildings

A ﬁve bus AC–DC hybrid transformerless nanogrid system for modern buildings, and its associated control strategy that can operate all the buses simultaneously, is proposed in this paper. The nanogrid has ﬁve buses that can exchange power among themselves. This feature improves the reliability of power availability in the system. Two DC buses and one AC bus can be operated in standalone mode as well as in grid connected mode which enables the scheme to operate with available DC microgrids and the AC utility grid. The PV array and the battery bank are interfaced with the remaining two buses which are PV bus, and the battery bus, respectively. In order to reduce the number of serially connected battery units, the voltage rating of the battery bus is kept low. Similarly, the voltage rating of the PV bus is maintained at a medium level to decrease the number of serially connected modules. Hence the effect of shading is minimized. The control strategy of the system is developed to judiciously operate all the buses. In order to validate the viability of the system, exhaustive experimental studies are carried out utilising a laboratory scale 1.2 kW nanogrid system developed for the purpose.
Cuffless Continuous Estimation of Relative Mean Arterial Pressure Using Unrestrained and Noncontact Ballistocardiogram and Electrocardiogram: Evaluation in Short Time In-bed Experiments

To facilitate capturing the characteristic variations of blood pressure (BP) such as BP surges during the nocturnal period, the in-bed continuous daily measurement of BP may be useful. In this study, we proposed and evaluated a method for cuffless continuous estimation of relative mean arterial pressure (MAP) using capacitive ballistocardiogram (cBCG) and electrocardiogram (cECG) measured using an unrestrained and noncontact method. We adapted a well-known equation for calculating MAP, which is equal to the product of cardiac output and peripheral vascular resistance. We then derived an estimation formula for the relative MAP using the J–K amplitude from the cBCG, heart rate from the cECG, and pulse beat arrival time calculated from the cBCG and cECG. To determine the coefficients for the estimation formula, we measured the MAP of a subject with a commercial device and used the least squares method. To obtain input data for the estimation formula, the cBCG from the heel of the right leg and cECG from the back of the subject were measured simultaneously with capacitively coupled electrodes placed under a bed sheet. The total length of the input data was 80 s for each Valsalva test (VT), and the Valsalva maneuver was used to increase BP during measurement. The data for each VT was separated into a training segment (Tr) and a test segment (Te). To evaluate the proposed estimation method, the following indices were calculated for each VT in 7 subjects: (1) correlation coefficient (CC) between estimated and reference MAP values, (2) confidence interval (CI), and (3) root mean square error (RMSE). For the Tr, average CC was 0.93 ± 0.06, average CI was 2.96 ± 1.29 mmHg, and average RMSE was 0.75 ± 0.33 mmHg. Furthermore, average RMSE for the Te was 2.49 ± 2.22 mmHg. These results indicate that the continuous cuffless method proposed in this study can be used for estimating relative MAP over a short time period. As the subjects in this study were all men in their early twenties, further validation in diverse subjects is required for broad application of the proposed method.
Does brand love matter to casual restaurants? A multi-group path analysis

ABSTRACT Previous research indicates that just satisfying customers is insufficient for retaining loyalty. Therefore, this research explores how to inspire and retain loyalty by adding an important construct, brand love, to the value-satisfaction-loyalty chain. Data were collected from guests of casual dining restaurants. The measurement scales adopted in this research were derived from the previous literature and adapted to the restaurant context. A multi-group path analysis was conducted to investigate whether the effects of brand love varied with gender, age, and income groups. This research confirmed that brand love is the outcome of excellent perceived value and a high level of satisfaction, and brand love is more important than perceived value and satisfaction in inspiring revisit intentions. This investigation emphasizes the importance of brand love for certain segments: women, Generation Xers, and people with higher incomes. It fills a gap in the literature by including brand love in the value-satisfaction-loyalty framework.
SUMOylation of S100A10 promotes its nuclear localization and enhances the migration and invasion of PGCCs and their daughter cells

Background Our previous studies have confirmed that cobalt chloride (CoCl2) or chemoradiotherapy could induce the formation of polyploid tumor giant cells (PGCCs) and daughter cells derived from PGCCs had strong proliferation and migration abilities. However, the detailed molecular mechanism is unclear. Methods Cell functional experiments, co-immunoprecipitation, MG132 and ginkgolic acid treatment, western blot, and ChiP-Seq were used to identify the mechanism of S100A10 nuclear location. Results CoCl2 was used to induce the formation of PGCCs in LoVo and HCT116 CRC cells. The proliferation and migration abilities of PGCCs and their daughter cells decreased significantly after S100A10 knockdown. In the control cells, S100A10 was mainly ubiquitinated, while in PGCCs and daughter cells, S100A10 was mainly SUMOylated, which was associated with S100A10 nuclear location. After SUMO1 was inhibited, the nuclear S100A10 in PGCCs and daughter cells decreased, and their proliferation and migration abilities significantly decreased. ChiP-Seq combined with real-time fluorescent quantitative PCR showed that S100A10 regulated the expression of neutrophil defensin 3 (DEFA3), receptor-type tyrosine-protein phosphatase N2 (PTPRN2), and rho guanine nucleotide exchange factor 18 (ARHGEF18). The expression of S100A10 in the nuclei and cytoplasm of rectal cancer after neoadjuvant chemoradiation (nCRT) and liver metastases increased compared with that in rectal cancer without nCRT. Conclusion The expression and nuclear localization of S100A10 modified by SUMOylation were associated with the high proliferation and migration of PGCCs and their daughter cells, and the differentiation, metastases, and relapse of CRCs by regulating the expression of ARHGEF18, PTPRN2, and DEFA3.
Peer mentoring in an extracurricular music class

The purpose of this study was to explore how high school students mentored beginning fifth-grade students in an extracurricular music class for double-reed instruments. In this study, I investigated the role of peer mentoring with how high school mentors shared their knowledge and experiences, and the role of the teacher in this process. The following questions guided this study: How did the participants share their knowledge and experiences during peer mentoring? How did the teacher serve as a guide for the student participants during peer mentoring? Data collection included observations and interviews during one semester of instruction, and analysis of the data collected involved a system of coding from which two themes developed: mentoring concurrent with director teaching and learning while mentoring. In addition, findings indicated that the participants used knowledge learned from outside sources, they reinforced content presented by the teacher, and they drew on their own musical knowledge during the process. Under the guidance of the teacher, the participants also learned how to share their knowledge that in turn helped elevate their individual levels of musicianship. Implications for music teachers suggest the use of peer mentoring to help create meaningful learning experiences in their classrooms and increase interaction among students.
