TL;DR: A new 7-dimensional model of self-reported ways of being independent or interdependent is developed and validated across cultures and will allow future researchers to test more accurately the implications of cultural models of selfhood for psychological processes in diverse ecocultural contexts.
Abstract: Markus and Kitayama’s (1991) theory of independent and interdependent self-construals had a major influence on social, personality, and developmental psychology by highlighting the role of culture in psychological processes. However, research has relied excessively on contrasts between North American and East Asian samples, and commonly used self-report measures of independence and interdependence frequently fail to show predicted cultural differences. We revisited the conceptualization and measurement of independent and interdependent self-construals in 2 large-scale multinational surveys, using improved methods for cross-cultural research. We developed (Study 1: N = 2924 students in 16 nations) and validated across cultures (Study 2: N = 7279 adults from 55 cultural groups in 33 nations) a new 7-dimensional model of self-reported ways of being independent or interdependent. Patterns of global variation support some of Markus and Kitayama’s predictions, but a simple contrast between independence and interdependence does not adequately capture the diverse models of selfhood that prevail in different world regions. Cultural groups emphasize different ways of being both independent and interdependent, depending on individualism-collectivism, national socioeconomic development, and religious heritage. Our 7-dimensional model will allow future researchers to test more accurately the implications of cultural models of selfhood for psychological processes in diverse ecocultural contexts.

TL;DR: Two proposed ABC algorithms with the best performances are compared against seven existing algorithms over by five benchmark cases and show the competitiveness of the proposed TABC algorithm for solving FJSP.
Abstract: This study addresses flexible job shop scheduling problem (FJSP) with two constraints, namely fuzzy processing time and new job insertion. The uncertainty of processing time and new job insertion are two scheduling related characteristics in remanufacturing. Fuzzy processing time is used to describe the uncertainty in processing time. Rescheduling operator is executed when new job(s) is (are) inserted into the schedule currently being executed. A two-stage artificial bee colony (TABC) algorithm with several improvements is proposed to solve FJSP with fuzzy processing time and new job insertion constraints. Also, several new solution generation methods and improvement strategies are proposed and compared with each other. The objective is to minimize maximum fuzzy completion time. Eight instances from remanufacturing are solved using the proposed TABC algorithm. The proposed improvement strategies are compared and discussed in detail. Two proposed ABC algorithms with the best performances are compared against seven existing algorithms over by five benchmark cases. The optimization results and comparisons show the competitiveness of the proposed TABC algorithm for solving FJSP.

TL;DR: A taxonomy of the best known techniques to realize genus 2-based cryptography, which includes fast formulas on the Kummer surface and efficient four-dimensional GLV decompositions, is given.
Abstract: In this paper, we highlight the benefits of using genus 2 curves in public-key cryptography. Compared to the standardized genus 1 curves, or elliptic curves, arithmetic on genus 2 curves is typically more involved but allows us to work with moduli of half the size. We give a taxonomy of the best known techniques to realize genus 2-based cryptography, which includes fast formulas on the Kummer surface and efficient four-dimensional GLV decompositions. By studying different modular arithmetic approaches on these curves, we present a range of genus 2 implementations. On a single core of an Intel Core i7-3520M (Ivy Bridge), our implementation on the Kummer surface breaks the 125 thousand cycle barrier which sets a new software speed record at the 128-bit security level for constant-time scalar multiplications compared to all previous genus 1 and genus 2 implementations.

TL;DR: In this article, the situation of non-camp Syrian refugees living in Izmir with a focus on socio-economic prospects and challenges concerning their survival and integration on the one hand and social acceptance by the host Turkish society on the other.
Abstract: This article investigates the situation of non-camp Syrian refugees living in Izmir with a focus on socio-economic prospects and challenges concerning their survival and integration on the one hand and social acceptance by the host Turkish society on the other. The data were generated by semi-structured interviews conducted between February and April 2014 with non-camp Syrian refugees and Turkish citizens living in Izmir. The empirical research intends to contribute to the literature through insights on the socio-economic conditions of non-camp Syrians, their level of integration to Turkish society, difficulties and challenges encountered and the perception of Turkish citizens about the rising Syrian population in Turkey. It argues that Turkey’s open-border and ‘temporary protection’ policies are approaching their limits with the increasing number of new arrivals and the concomitant difficulties faced in integrating into Turkish society. The paper suggests that there is an urgent need to create a ...

TL;DR: In a range of empirical comparisons, Anya is competitive with several recent (sub-optimal) online and pre-processing based techniques and is up to an order of magnitude faster than the most common benchmark algorithm, a grid-based implementation of A.
Abstract: Any-angle pathfinding is a fundamental problem in robotics and computer games. The goal is to find a shortest path between a pair of points on a grid map such that the path is not artificially constrained to the points of the grid. Prior research has focused on approximate online solutions. A number of exact methods exist but they all require super-linear space and pre-processing time. In this study, we describe Anya: a new and optimal any-angle pathfinding algorithm. Where other works find approximate any-angle paths by searching over individual points from the grid, Anya finds optimal paths by searching over sets of states represented as intervals. Each interval is identified on-the-fly. From each interval Anya selects a single representative point that it uses to compute an admissible cost estimate for the entire set. Anya always returns an optimal path if one exists. Moreover it does so without any offine pre-processing or the introduction of additional memory overheads. In a range of empirical comparisons we show that Anya is competitive with several recent (sub-optimal) online and pre-processing based techniques and is up to an order of magnitude faster than the most common benchmark algorithm, a grid-based implementation of A.

TL;DR: Extensive computational results on the Taillard’s well-known benchmark suite show that the proposed VBIH algorithm outperforms the discrete artificial bee colony algorithm, which is one of the most efficient algorithms recently in the literature.
Abstract: In this paper, we present a variable block insertion heuristic (VBIH) algorithm to solve the blocking flowshop scheduling problem with the total flowtime criterion. In the VBIH algorithm, we define a minimum and a maximum block size. After constructing the initial sequence, the VBIH algorithm starts with a minimum block size being equal to one. It removes the block from the current sequence and inserts it into the partial sequence sequentially with a predetermined move size. The sequence, which is obtained after several block moves, goes under a variable local search (VLS), which is based on traditional insertion and swap neighborhood structures. If the new sequence obtained after the VLS local search is better than the current sequence, it replaces the current sequence. As long as it improves, it keeps the same block size. However, if it does not improve, the block size is incremented by one and a simulated annealing-type of acceptance criterion is used to accept the current sequence. This process is repeated until the block size reaches at the maximum block size. Furthermore, we present a novel constructive heuristic, which is based on the profile fitting heuristic from the literature. The proposed constructive heuristic is able to further improve the best known solutions for some larger instances in a few seconds. Parameters of the constructive heuristic and the VBIH algorithm are determined through a design of experiment approach. Extensive computational results on the Taillard’s well-known benchmark suite show that the proposed VBIH algorithm outperforms the discrete artificial bee colony algorithm, which is one of the most efficient algorithms recently in the literature. Ultimately, 52 out of the 150 best known solutions are further improved with substantial margins.

TL;DR: In this paper, a multistep ahead approach is proposed to forecast construction costs at the conceptual phases of building projects, which relies on the idea of using several cascaded estimations to predict future values.
Abstract: Providing accurate forecasts of construction costs at the conceptual phases of building projects is vital since they form an objective benchmark for the subsequent evaluation of project performance. Previous works adopted a conventional approach in which a restricted set of macro project determinants, which are available in the preplanning phase, was employed towards direct estimation of construction costs. Aiming to reduce the prediction error in conceptual estimates, the current study adopts a novel approach from the domain of forecasting. This multistep ahead (MSA) approach relies on the idea of using several cascaded estimations to predict future values. Accordingly, building element quantities were estimated as the first step. In the second step, estimated quantities were combined with the existing set of inputs to achieve a higher accuracy in construction cost prediction. In order to test the hypotheses of interest, 657 building projects from Germany were analyzed using linear regression and...

TL;DR: In this paper, the role of non-state actors in foreign policy implementation in Turkey has been investigated and a parallelism has been identified between Islamically oriented humanitarian NGOs (HNGOs) and the AKP foreign policy.
Abstract: This paper aims to contribute to the growing Foreign Policy Analysis literature by focusing on the role of non-state actors in foreign policy implementation. Special attention is paid to the case of Turkey, which has emerged as a ‘humanitarian state’ in the last decade. In Turkey, relatively new Islamically oriented humanitarian NGOs (HNGOs) have been providing ever-increasing amounts of humanitarian aid throughout the former Ottoman lands including the Middle East and Africa. Employing a constructivist-realist perspective, this paper asserts that a ‘parallelism,’ if not a complementarity, exists between Turkey’s Islamically oriented HNGO discourse and practice and AKP foreign policy implementation process. Based on primary qualitative data acquired from interviews, this study has identified various degrees of parallelism between the two, calling into question the status of these HNGOs as purportedly non-governmental entities.

TL;DR: This paper explores an alternative approach, which builds on machine-learning algorithms that inductively learn from simulation-derived data, yielding models that approximate to a good degree and are orders of magnitude faster.
Abstract: In performance-oriented architectural design, the use of advanced computational simulation tools may provide valuable insight during design. However, the use of such tools is often a bottleneck in the design process, given that computational requirements are usually high. This is a fact that mostly affects the early conceptual stage of design, where crucial decisions mainly occur, and available time is limited. In order to deal with this, decision-makers frequently resort to drawing conclusions from experience, and, as such, valuable insight that advanced computational methods have to offer is lost. This paper explores an alternative approach, which builds on machine-learning algorithms that inductively learn from simulation-derived data, yielding models that approximate to a good degree and are orders of magnitude faster. We focus on visual comfort of office spaces. This is a type of space that specifically requires visual comfort more than others. Three machine-learning methods are compared with respect...

TL;DR: In this article, the extent to which point defects affect the local chemical reactivity and electronic properties of an oxide surface was evaluated with picometer resolution in all three spatial dimensions using simultaneous atomic force/scanning tunneling microscopy measurements performed on the (110) face of rutile TiO2.
Abstract: The extent to which point defects affect the local chemical reactivity and electronic properties of an oxide surface was evaluated with picometer resolution in all three spatial dimensions using simultaneous atomic force/scanning tunneling microscopy measurements performed on the (110) face of rutile TiO2. Oxygen atoms were imaged as protrusions in both data channels, corresponding to a rarely observed imaging mode for this prototypical metal oxide surface. Three-dimensional spectroscopy of interaction forces and tunneling currents was performed on individual surface and subsurface defects as a function of tip-sample distance. An interstitial defect assigned to a subsurface hydrogen atom is found to have a distinct effect on the local density of electronic states on the surface, but no detectable influence on the tip-sample interaction force. Meanwhile, spectroscopic data acquired on an oxygen vacancy highlight the role of the probe tip in chemical reactivity measurements.

TL;DR: This paper proposes a target identification method in the resonance scattering region using a novel structural feature set based on the scattered signal waveform using an overlapping grid hierarchical radial basis function (HRBFOG) network topology, which is demonstrated to outperform existing HRBF techniques.
Abstract: Classification of objects from scattered electromagnetic waves is a difficult problem, as it heavily depends on aspect angle. To minimize this dependency, distinguishable features can be used. In this paper, we propose a target identification method in the resonance scattering region using a novel structural feature set based on the scattered signal waveform. To obtain robustness at low signal-to-noise ratio (SNR), a multiscale approximation is used for distortion correction prior to the feature extraction. This is achieved by an overlapping grid hierarchical radial basis function (HRBF $_{\mathrm {\mathrm {OG}}})$ network topology, which is demonstrated to outperform existing HRBF techniques. The results obtained from the simulations and the measurements performed for various targets show high accuracy for classification with the proposed feature set, robustness through the use of HRBF at low SNR, and efficient computation in real time.

TL;DR: In this article, the authors focused on the role of Islam in shaping socially responsible behavior among businesses and provided an integrated model of CSR within Islam by using CSR Pyramid on economic, legal, ethical, and philanthropic responsibilities.
Abstract: Corporate social responsibility (CSR) has been widely accepted as a useful framework between business and society during the last decades. Depending on its increasing popularity among business enterprises, the scholars have also focused on its antecedents and consequences. As a significant reference for many people’s lives, religion has been seen as one of these antecedents which affect attitudes and behaviours of decision makers towards CSR. The current study particularly focuses on the role of Islam in shaping socially responsible behaviour among businesses. In doing so, the study follows the key texts of Islam and provides an integrated model of CSR within Islam by using CSR Pyramid on economic, legal, ethical, and philanthropic responsibilities. This critical perspective shows that Islam provides a strong support for the existence of these dimensions both on the theoretical (aqidah) and practical (ibadah) levels from an anthropocentric approach. Among these dimensions, the philanthropy attracts the attention of many businesses operating in the Muslim countries. Therefore, contrary to what many people think, these Islamic roots are closely overlapping with dominant Western paradigm on CSR. However, these spiritual approaches must be backed up with a sound institutional mechanism in order to strengthen CSR within the business community in Muslim countries.

TL;DR: In this article, the authors tried to figure out whether there is a relation between self-assessment quiz taking behaviours and final exam scores or not, and they investigated how learners' self assessment quiz taking behaviour differs with respect to learner profile.
Abstract: Abstract Self-assessment is vital for online learning since it is one of the most essential skills of distance learners. In this respect, the purpose of this study was to understand learners’ self-assessment quiz taking behaviours in an undergraduate level online course. We tried to figure out whether there is a relation between self-assessment quiz taking behaviours and final exam scores or not. In addition, we investigated how self-assessment quiz taking behaviour differs with respect to learner profile. In line with this purpose, 677 students’ 6092 test events across Project Culture course on Sakai CLE LMS were analyzed. For the analysis of the quantitative data, one-way ANOVA, Chi-Square test of independence, independent-samples t-test and descriptive statistics were utilized. The results revealed that learners who attended self-assessment quizzes regularly had higher final exam scores than others who did not attend those quizzes. Also, they were more satisfied with the course than others study field. In addition, learners who attended selfassessment quizzes regularly had a higher degree of perceived learning. However, number of attempts to those quizzes does not have an effect on final exam scores. On the other hand, a statistically significant relationship was found between attempt number and gender in favour of female learners.

TL;DR: In this article, the authors take a customer focus that prioritises the service-offering dimensions of LCs by considering potential LC customer expectations and LC service characteristics and find that customer preferences mainly prioritise infrastructure, and warehouse and intermodal dimensions, while higher utility values are delivered through soft service dimensions like value-added or standard services.
Abstract: This study takes a customer focus that prioritises the service-offering dimensions of logistics centres (LCs) by considering potential LC customer expectations. Applying a survey and a quality function deployment methodology to logistics service providers, the study explores, categorises and prioritises LC customer expectations and LC service characteristics. The results indicate that customer preferences mainly prioritise infrastructure, and warehouse and intermodal dimensions. However, when the cost dimension is included, higher utility values are delivered through soft service dimensions like value-added or standard services. LC investors or undertakers can use these results to guide their design of market offerings by using the same methodology to assess expectations in their target markets.

TL;DR: A memetic algorithm with a variable block insertion heuristic is presented to solve the single machine total weighted tardiness problem with sequence dependent setup times and is able to find 98 out 120 optimal solutions within reasonable CPU times.
Abstract: In this paper, a memetic algorithm with a variable block insertion heuristic is presented to solve the single machine total weighted tardiness problem with sequence dependent setup times. Together with the traditional insertion neighborhood structure, the memetic algorithm is combined with a variable block insertion heuristic in which a block of jobs are removed from a sequence and then inserted into all possible positions of the partial sequence. For this purpose, we devise a variable neighborhood descent algorithm to incorporate different block insertion heuristics having different block sizes. We also employ a simulated annealing type of acceptance criterion to diversify the population. To evaluate its performance, the memetic algorithm is tested on a set of benchmark instances from the literature. The analyses of experimental results have shown highly effective performance of the memetic algorithm against the best performing algorithms from the literature. The proposed memetic algorithm was able to find 98 out 120 optimal solutions within reasonable CPU times.

TL;DR: In this paper, the authors explore the process and outcome of using learner-centred methods to develop students' empathic design abilities during an educational workshop on inclusive design, and suggest the significance of incorporating inclusive design within the education of design disciplines.
Abstract: This paper explores the process and outcome of using learner-centred methods to develop students’ empathic design abilities during an educational workshop on inclusive design. In the first section of the paper, we suggest the significance of incorporating inclusive design within the education of design disciplines. Then, we introduce a workshop on inclusive design awareness that architecture and interior design students participated, which applied various learner-centred methods. We discuss the process that incorporated project-based learning, role-playing/simulation and students’ reflections and feedback on their experience. The workshop process, the student project experience and students’ reflections on their learning indicate how multiple methods of learning engage students and enhance their empathic understanding so they can embrace differences and adopt a user-centred design approach. Based on the findings, we provide suggestions for similar educational events that can be applied in other di...

TL;DR: In this paper, the authors address the question of whether and when religious parenting is a bridge or a barrier to Muslim immigrant children's integration, defined as children's identification with the heritage culture and the host culture.
Abstract: This study addresses the question of whether and when religious parenting is a bridge or a barrier to Muslim immigrant children’s integration. Integration was defined as children’s identification with the heritage culture and the host culture. Participants included 210 self-identified Turkish Muslim mothers, children (aged 9-14), and 115 fathers in Germany. All family members filled in questionnaires on identification with Turks and identification with Germans; in addition both parents reported on religious parenting and children on religiosity. Results of multivariate regression analyses revealed that religious parenting was negatively related to children’s identification with Germans but positively related to children’s identification with Turks through increased child religiosity. However, additional multiple-group analyses revealed that only the religious parenting of lower educated parents and first-generation mothers reduced the likelihood of children’s identification with Germans. The religious par...
