Why Do College Students Cheat? A Structural Equation Modeling Validation of the Theory of Planned Behavior

Cheating on tests is a serious problem in education. The purpose of this study was to test the efficacy of a modified form of the theory of planned behavior (TPB) to predict cheating behavior among a sample of Saudi university students. This study also sought to test the influence of cheating in high school on cheating in college within the framework of the TPB. Analyses were conducted on a sample of 322 undergraduate students using structural equation modeling. The results were consistent with the TPB model’s predictions. The TPB model explained a modest variance in cheating in college. When cheating in high school added to the model, the proportion of explained variance increased and cheating in high school was the best predictor of cheating in college. Although not hypothesized by the TPB, subjective norm had a direct effect on attitude.

Co-regulation and the quality of the relationship during face-to-face interactions in full-term and very low birthweight preterm infant-mother dyads

Interactions with parents form the basis of infants’ social-emotional development. Co- regulation during interactions occurs when partners adjust behaviour based on cues from each other. Research has examined co-regulation in low-risk populations, however co-regulation in the context of dyads’ relationships in at-risk populations has yet to be explored. The present study investigated co-regulation and quality of relationships between mothers and their 6-month- old full-term (n = 43) and very low birthweight/preterm (VLBW/preterm; n = 44) infants. The objectives were to examine: (1) how co-regulation changed following a perturbed interaction, (2) how co-regulation differed between full-term and VLBW/preterm infant-mother dyads, and (3) the association between co-regulation and the quality of the mother-infant relationship. Mother-infant interactions were coded for time spent in patterns of co-regulation using the Revised Relational Coding System (Fogel et al., 2003). Quality of the mother-infant relationship was assessed using the Emotional Availability Scales examining maternal and infant dimensions (Biringen et al., 2014; Carter, Little, & Garrity, 1998). Dyads participated in the Still-Face (SF) procedure (Tronick et al., 1978) consisting of two 2-minute face-to-face interactions with a 2-minute period in between where mothers assumed a “still face” and refrained from interacting with their infants. Following the SF period, dyads engaged in more active and disruptive patterns of co-regulation. While full-term dyads engaged in more sequential-symmetrical, VLBW/preterm dyads engaged in more resonant-symmetrical co- regulation. Infant responsiveness, maternal sensitivity, and parental stress were associated with co-regulation. The results highlight the importance of co-regulation and the influence of risk status and relationship quality on co-regulation.
Gellan gum based thiol-ene hydrogels with tunable properties for use as tissue engineering scaffolds

Gellan gum is a naturally occurring polymer that can crosslink in the presence of divalent cations to form biocompatible hydrogels. However, physically crosslinked gellan gum hydrogels lose stability under physiological conditions, which substantially limits the applications of these hydrogels in vivo. In order to improve the mechanical strength, we incorporated methacrylate into gellan gum and chemically crosslinked the hydrogel through three polymerization methods: step growth through thiol-ene photoclick chemistry, chain growth via photopolymerization, and mixed model in which both mechanisms were employed. Methacrylation was confirmed and quantified by proton nuclear magnetic resonance (1H NMR) and Fourier transform infrared spectroscopy (FTIR). The mechanical property and chemistry of the crosslinked gels were systematically explored by varying the reaction conditions. The swelling ratios of the hydrogels were correlated with the compression moduli and affected by the addition of calcium. In vitro enzymatic degradation rate was found dependent on the degree of methacrylation. NIH/3T3 fibroblast cell proliferation and morphology were related to substrate stiffness with high stiffness leading generally to higher proliferation. The proliferation is further affected by the thiol-ene ratios. We then further modified methacrylate Gellan gum with alkane bromide to increase hydrophobicity. Cell attachment on resultant hydrogels were assessed and imaged. Cytokine release was also measured with comparison to pristine methacrylated Gellan gum based hydrogels. The results suggest that a hydrogel platform based on gellan gum can offer versatile chemical modifications and tunable mechanical properties for a variety of biomaterials applications, such as the wound healing scaffold.
Towards a sociology of the mobile phone

Use of the mobile phone is an immensely significant social and cultural phenomenon. However, market hype and utopian dreams greatly exaggerate its importance. The fundamental issue for sociology is the process of change. Bound up with contemporary issues of change, the mobile phone is a prime object for sociological attention both at the macro and micro levels of analysis. This article considers the strengths and weaknesses of four methods for studying the sociality of the mobile phone (social demography; political economy; conversation, discourse and text analysis; and ethnography), the different kinds of knowledge they produce, and the interests they represent. Recent ethnographic research on the mobile phone, particularly motivated by issues around the uncertain transition from 2G to the 3G technology, has examined the actual experience of routine use. Interpretative research is now supplementing purely instrumental research, thereby giving a much more nuanced understanding of mobile communications. Critical research on the mobile phone, of which there is little, is beginning to ask skeptical questions that should be pursued further.
Tone and Intonation in Chichewa and Tumbuka

This study compares the tone and intonation systems of two closely related Bantu languages spoken in Malawi, Chichewa and Tumbuka. The lexical tone systems of the two languages are quite different from each other. Chichewa uses tone contrastively and grammatically. In Tumbuka, tone is predictable except in the ideophonic system. Only Tumbuka provides evidence for both a Phonological Phrase and an Intonation Phrase level. It is surprising, then, that the intonation systems of the two languages turn out to be quite similar. Both have penult lengthening and similar intonation patterns for statements and questions. Both use continuation rises following preverbal topics, and have final lowering at the end of declarative utterances. These similarities raise the question of whether intonation might be an areal phenomenon.
Cognitive Processing in Mild Disabilities.

Research regarding the cognitive processing of students with learning disabilities, mild mental handicap, and emotional handicap is reviewed. In considering cognitive processing for students with mild mental handicap, research attention has been directed to the issues of memory and learning, acquisition and retrieval deficits, inefficient strategic plans, executive function, inadequate tactics and metastrategies implementation, production anomalies, and levels of processing. The following major topics have been addressed in cognitive processing research for students with emotional handicap: memory and learning, intellectual functioning, information processing, and levels of processing. The review found that there has been more research on cognitive processing of students with learning disabilities and mild mental handicap than on students with emotional handicap. The paper concludes that the argument used to support that students with mild disabilities have processing deficiency can also be used to suggest that they have neurological problems and structural differences. However, students' task performance can be improved with the appropriate use of learning strategies. (Contains 60 references.)

Frequency‐domain optimization of fixed‐structure controllers

This paper aims to introduce a new approach to optimize the tunable controller parameters of linear parameterizable controllers. The presented approach is frequency‐domain based and can therefore directly be used to tune, among others, proportional integral derivative controllers, low/high‐pass filters, and notch filters, using a Frequency Response Function of the plant. The approach taken in this paper is to extract the tunable controller parameters into a diagonal matrix gain and absorb the remainder of the controller in the plant. Then, the generalized Nyquist stability criterion is exploited so as to impose stability and H∞ performance specifications on the closed‐loop system. It is shown that the approach results in a convex feasibility problem for certain controller cases and can be reformulated such that it can also be used for grey‐box system identification. Simulation and experimental examples demonstrate the efficacy of the approach. © 2016 The Authors. International Journal of Robust and Nonlinear Control published by John Wiley & Sons, Ltd.
7 Assumption-Based Argumentation : Disputes , Explanations , Preferences

Assumption-Based Argumentation (ABA) is a form of structured argumentation with roots in non-monotonic reasoning. As in other forms of structured argumentation, notions of argument and attack are not primitive in ABA, but are instead defined in terms of other notions. In the case of ABA these other notions are those of rules in a deductive system, assumptions, and contraries. ABA is equipped with a range of computational tools, based on dispute trees and amounting to dispute derivations, and benefiting from equivalent views of the semantics of argumentation in ABA, in terms of sets of arguments and, equivalently, sets of assumptions. These computational tools can also provide the foundation for multi-agent argumentative dialogues and explanation of reasoning outputs, in various settings and senses. ABA is a flexible modelling formalism, despite its simplicity, allowing to support, in particular, various forms of non-monotonic reasoning, and reasoning with some forms of preferences and defeasible rules without requiring any additional machinery. ABA can also be naturally extended to accommodate further reasoning with preferences.
Increasing IPM Knowledge Through FFS in Benin

Over the next two generations 4 billion more people will live in cities, increasing the proportion of the urban population from 50 to 80 per cent of the total world population (NRC, 1999). Thus a sustainable development needs to focus on meeting the needs of an increasing human population, reducing poverty and hunger while at the same time sustaining the life support systems of the planet (NRC, 1999). While the Green Revolution technologies enabled extensive monocultures and higher yields through improved seeds, chemical fertilizers and synthetic pesticides, biodiversity in and around the agro-ecosystems have been reduced, causing the loss of natural pest and disease control (Gallagher et al., 2005). This has increased the need for synthetic pesticides in the agricultural sector to the current global use of 2.56 billion kg yr−1 (Pretty, 2008), with associated negative effects for humans and the ecosystem becoming evident. While the externalities of pesticides in rice systems in China cost $1.4 billion per year through adverse effects on biodiversity and people’s health (Norse et al., 2001), the annual mortality rate due to pesticides in the remote Ecuadorian highlands is among the world’s highest, 21 per 100 000 people (Sherwood et al., 2005). On the other hand, in the Philippines, agricultural systems that do not use any synthetic pesticides experience higher net social benefits due to reduced illnesses among farmers and their families, and associated lower medical costs (Rola & Pingali, 1993, Pingali & Roger, 1995). According to FAO and ILO estimates, 2 to 5 million agricultural workers yearly experience severe pesticide poisoning and related illnesses of which 40 000 are lethal (FAO & ILO, 2009). However, pesticide poisoning incidents are often underreported, as indicated by a study among farmers in Senegal, Mali and Benin, where over 80% of the respondents faced adverse effects after spraying pesticides, to the extent of blurred vision, unconsciousness or severe dizziness, but only 2% sought medical attention for these symptoms (Thiam & Touni, 2009). Thus recent studies, where 4% to 9% of the surveyed farmers reported poisoning incidents the last year, estimate a yearly 25 – 45 million poisoning cases (Kishi, 2005). Africa only accounts for 4% of pesticides used globally, an estimated 75-100 metric tons of pesticide active ingredient (compared to 350,000 tons in Europe), and average pesticide use per hectare cultivated land in Africa (1.23kg/ha) is very low compared to Latin America and Asia (7.17kg/ha and 3.12kg/ha respectively) (Thiam & Touni, 2009). Still, the risks and impacts associated with synthetic pesticides are not necessarily lower in Africa as many of the pesticides used in the continent are adulterated, poor quality and unlabelled and application and handling practices are often highly unsafe (Thiam & Touni, 2009, Lund et
COOPERATIVE MULTIPLE MOBILE MANIPULATORS TRANSPORTING A COMMON PAY- LOAD: AN INTEGRATED APPROACH CAIO

 In this work we present a study concerning the modeling and control of two cooperative mobile manipulators for transport and manipulation of payloads. The advantages of such system can be summarized by the general system capacities in terms of size, weight and shape of payload to be transported, intricate moves and maneuvers and a wide range of applications. The study has an emphasis in the motion modeling and control of the system. The system is nonlinear and cannot be controlled by traditional linear control techniques. The motion is divided in the transport phase and the manipulation phase. In the transport phase, two mobile platforms carry the payload in a trajectory controlling the driving wheels in a formation control and in the manipulation phase, two manipulators carries the payload in a trajectory controlling the revolute joints. The control strategy proposed for the transport phase is the leader-follower with SDRE (State-Dependent Riccati Equation) method applied on formation control and the control strategies proposed for the manipulation phase are the SDRE method and the Variable Structure with Sliding Mode method. Simulation results with the software Matlab show the efficiency of the control strategies. Keywords Cooperative Mobile Manipulation, Autonomous Robotics, SDRE Control, Variable Structure with Sliding Mode Control.
Human Umbilical Vein Endothelial Cells Migration in Matrigel by the Concentration Gradient of Vascular Endothelial Growth Factor

Vascular endothelial growth factor (VEGF) has an ability to induce the migration of human umbilical vein endothelial cells (HUVEC). The objective of this study is to prepare several patterns of gelatin hydrogels for VEGF release and evaluate the 3-dimensional pattern of HUVEC migration in Matrigel by VEGF release. VEGF was incorporated into the gelatin hydrogel sheet to achieve the sustained release and generate the concentration gradient of VEGF. When Matrigel was put on the gelatin hydrogel sheet incorporating VEGF, the VEGF was released into the Matrigel to form a gradient pattern of VEGF concentration in the Matrigel with time and the area of VEGF released by the Matrigel depended upon the position of gelatin hydrogel sheet put on. In addition, HUVEC were seeded on the surface of Matrigel to evaluate the ability of VEGF released to enhance the cell migration into the Matrigel. HUVEC were migrated with time into the Matrigel to the direction and the position of VEGF released. It is concluded that the VEGF release induces the migration of HUVEC in Matrigel based on the concentration gradient and the position of VEGF formed in Matrigel.
Pre and Post Test Suite Reduction Techniques: A Comparison Study

Test suite reduction is a critical activity which occurs pre or post test cases generation process. As software keeps growing large amounts of new test cases will be generated and added to the test pool and others will be updated. Accordingly test suite size will increase. Test suite reduction techniques have been proposed to eliminate redundant or irrelevant test cases based on variant criteria, while seeking to maintain the total effectiveness of the reduced test suite. In this paper we address and compare four test case reduction techniques: CBR (case-based reasoning) deletion algorithms Technique, GE & GRE Heuristics and priority cost technique, Model-checker based technique and Base choice coverage criterion technique. The aim of the study is to provide a guideline for choosing the appropriate test suite reduction techniques. Keywords: test suite reduction techniques, requirement test coverage.
College students’ understanding of logical implication

In this paper we present the results of student testing, from two technical colleges at Banja Luka University, on understanding and applying the logical implication and its contraposive in a realworld situation. The findings support our belief that the tested population has insufficient knowledge of these logical concepts. Furthermore, we argue that these results could reveal the critical link between conceptual and procedural knowledge of these logical tools.
PHOTONIC CRYSTAL NARROW FILTERS WITH NEGATIVE REFRACTIVE INDEX STRUCTURAL DEFECTS

This paper presents a proposal of taking the left-handed material as the structural defects of one-dimensional photonic crystals and uses the transfer matrix method to analyze the band-gap of that structure. The simulation result shows that the structure investigated can be considered as a narrow pass band optical filter. By tuning the refractive index of the left-handed material, the ideal transmission rate in the pass band is as higher as 99.99%, while in the band-gap is lower than 0.01%. In addition, we show that the bandwidth can be increased by reducing the cycle number of the photonic crystals.
Modeling Methodologies for Cyber-Physical Systems : Research Field Study on Inherent and Future Challenges

This paper presents a field study about the inherent challenges involved in the design of Cyber-Physical Systems and how Model-Based Design (MBD) is currently being utilized in various research directions in order to help in the design and development of these complex systems. The paper then presents the first future directions and challenges deemed to be tackled by H2020 INTOCPS project. The aim of INTO-CPS project is to create an integrated “tool chain” for comprehensive Model-Based Design of Cyber-Physical Systems (CPSs). The tool chain will support the multidisciplinary, collaborative modeling of CPSs from requirements, through design, down to hardware and software implementation. This will enable traceability at all stages of the development process. The paper aims at analyzing the current State-of-the-Art related to CPSs and be a basis to future extensions of the SysML standard to support CPS modeling within the INTO-CPS project.
Simple Methods for Repeatability and Comparability : Bland-Altman Plots , Bias , and Measurement Error

While a Pearson correlation coefficient may be a quick and easy measure to compare two different measurement methods or examine repeatability of a measure it is not the most appropriate nor does it give you insight into bias. Additionally, performing linear regression or tests for differences between the means is also not the best approach for determining whether two methods are comparable or a measurement is repeatable. Examining the difference between the measurements may not offer insight into the accuracy of the methods and a Pearson product moment correlation coefficient is not a measure of agreement but a measure of association. Altman and Bland (1983) suggested a graphical method and two other statistical tests to examine repeatability of measurement or whether two methods of measurement produced similar results. The graphical method, called a Bland-Altman plot, is a plot of the difference versus the average of two different measures with y-reference lines at ±2 standard deviations (SD) or ±3SD of the difference. A Bland-Altman plot allows for assessment of the magnitude of disagreement, both error and bias. A systolic blood pressure example will be used to show how to perform the statistical tests and create the Bland-Altman plot using SAS® STAT/PROC TTEST, BASE/PROC CORR, and ODS Statistical Graphic SGPLOT. Calculation of Lin’s CCC and Kendall’s tau will also be presented.
Textile Fingerprinting for Dismount Analysis in the Visible, Near, and Shortwave Infrared Domain

Abstract : The ability to accurately and quickly locate an individual, or a dismount, is useful in a variety of situations and environments. A dismount's characteristics such as their gender, height, weight, build, and ethnicity could be used as discriminating factors. Hyperspectral imaging (HSI) is widely used in e orts to identify materials based on their spectral signatures. More speci cally, HSI has been used for skin and clothing classi cation and detection. The ability to detect textiles (clothing) provides a discriminating factor that can aid in a more comprehensive detection of dismounts. This thesis demonstrates the application of several feature selection methods (i.e., support vector machines with recursive feature reduction, fast correlation based lter) in highly dimensional data collected from a spectroradiometer. The classi cation of the data is accomplished with the selected features and arti cial neural networks. A model for uniquely identifying ( ngerprinting) textiles are designed, where color and composition ard deternimed in order to ngerprint a speci c textile. An arti cial neural network is created based on the knowledge of the textile's color and composition, providing a uniquely identifying ngerprinting of a textile. Results show 100% accuracy for color and composition classi cation, and 98% accuracy for the overall textile ngerprinting process.
