Bullying, Cheating, Deceiving: Teachers’ Perception of Deceitful Situations at School

Two studies investigated in which situations teachers (would) investigate whether a student was lying or telling the truth and how these situations were perceived. Results of Study 1 indicate that teachers (would) interview students when it comes to use of unfair means, aggressive behavior, theft, absence without permission, bullying, and vandalism, whereat deceitful situations with rather light consequences were most frequently described. Moreover, participants perceived the frequency of occurrence of all situations as lower for themselves compared to colleagues. In both studies, the use of unfair means, absence without permission, and bullying (over a longer period) were rated as most frequently occurring in everyday school life. Further, deception detection was perceived as being mostly important in situations with severe consequences. Study 2 also demonstrates that situations with light consequences are perceived as situations where it is of relatively less importance to make accurate judgments, avoid wrongful accusation, and detect misbehavior, as compared with situations with severe consequences. Overall, teachers perceive avoiding wrong accusation as more important than detecting misbehavior. Influences of teachers’ perceptions on their behavior are discussed.
The Role of Channel Distribution Information for Interference Management and Network Performance Enhancement

Abstract : One of the key technologies proposed for next generation commercial and military communications systems is the use of multiple antennas at both the transmitting and receiving nodes of the network. The additional antenna elements provide degrees of freedom that can provide spatial filtering, spatial multiplexing and diversity gain. These advances can be applied to increase link gain, provide interference management, mitigate hostile jammers and facilitate multi-packet reception. In this project we defined how the channel statistics can be utilized in place of the instantaneous channel state information to limit the amount of power that must be transmitted between nodes to improve overall network performance by maintaining stable beam forming vectors over the time scales defined by channel distribution information rather than the reduced time scale associated with the channel coherence time. With CDI, one can only guarantee quality of service for a specified outage probability. This creates a tradeoff that can be beneficial to the overall network. Closed form expressions for the outage probabilities were derived and given those expressions, algorithms were derived that minimize the weighted sum power in the network for a specified outage probability.
Phonon dispersion of graphite by inelastic x-ray scattering

We present the full in-plane phonon dispersion of graphite obtained from inelastic x-ray scattering, including the optical and acoustic branches, as well as the mid-frequency range between the $K$ and $M$ points in the Brillouin zone, where experimental data have been unavailable so far. The existence of a Kohn anomaly at the $K$ point is further supported. We fit a fifth-nearest neighbour force-constants model to the experimental data, making improved force-constants calculations of the phonon dispersion in both graphite and carbon nanotubes available.
Analyzing Reaction Times Análisis de los tiempos de reacción

Reaction times (RTs) are an important source of information in experimental psychology. Classical methodological considerations pertaining to the statistical analysis of RT data are optimized for analyses of aggregated data, based on subject or item means (c.f., Forster & Dickinson, 1976). Mixed-effects modeling (see, e.g., Baayen, Davidson, & Bates, 2008) does not require prior aggregation and allows the researcher the more ambitious goal of predicting individual responses. Mixed-modeling calls for a reconsideration of the classical methodological strategies for analysing rts. In this study, we argue for empirical exibility with respect to the choice of transformation for the RTs. We advocate minimal apriori data trimming, combined with model criticism. We also show how trial-to-trial, longitudinal dependencies between individual observations can be brought into the statistical model. These strategies are illustrated for a large dataset with a non-trivial random-effects structure. Special attention is paid to the evaluation of interactions involving fixed-effect factors that partition the levels sampled by random-effect factors.
Using the Stages of Concern Questionnaire to Ensure Professional Development with Teachers and Teacher Candidates

Classroom instruction is highly influenced by the quality of the professional development that teachers and teacher candidates receive. Instructional interventions at the classroom level must be research-based, and working with teachers and teacher candidates to implement interventions effectively is a daunting task. One way to help ensure professional development is effective involves gauging teachers’ and teacher candidates’ concerns, using the Stages of Concern Questionnaire (SOCQ) from the Concerns Based Adoption Model (CBAM). In the current study, teacher candidates received professional development at the pre-service level, and teachers received the same professional development at the in-service level. Both groups were taught specific interventions designed to target middle and secondary students using the Strategic Instruction Model Content Enhancement Routines. The SOCQ was administered prior to and following a professional development series that spanned several months. An analysis of results indicated that professional development is effective in reducing concern in both teachers and teacher candidates. Teachers and teacher candidates overall shared similar concerns on some areas yet were different in their levels of concern in other areas. The researchers suggest possible interpretations for the similarities and differences in results and offer areas for future study.
Project Complexity Mapping in Five Dimensions for Complex Transportation Projects

Traditional three-dimensional project management theory is based on optimizing the cost-schedule-technical dimensions. Recent studies in the United Kingdom, Canada, and Australia have shown that the current project management body of knowledge may not be adequate to address interrelated and dependent variables encountered on complex projects. This paper reports the findings of an international research team’s detailed study of 18 complex projects, which confirms the findings of the previous research and proposes a framework upon which a complex transportation project’s scope of work can be better conceptualized and a methodology to graphically display a project’s complexity in order to better understand and prioritize the available resources. The result is a “complexity footprint” that helps the complex transportation project manager identify the sources of complexity so that appropriate resources can be allocated to address those factors before they create a crisis.

A simple in vitro method to study interactions between soil insects, entomopathogenic fungi, and plant extracts

A combined application of a biological control agent, such as an entomopathogenic fungus (EPF), with other means of pest control may lead to enhanced or more reliable efficacy of the biocontrol agent. Ideally, the combined components would interact synergistically, yielding significantly higher mortality of the target pest. The mode of such interactions is often unclear and particularly difficult to elucidate for soil‐dwelling pests. Here, an efficient image analysis protocol was developed to study behavioural responses of soil‐dwelling insects to application of control measures in two‐dimensional terraria. The interactions between the EPF Metarhizium brunneum Petch (Hypocreales), a supposedly repellent extract of garlic, Allium sativum L. (Amaryllidaceae), and wireworms, Agriotes obscurus (L.) (Coleoptera: Elateridae), as target hosts were investigated. Tunnelling activity and mortality of wireworms were studied under choice and no‐choice situations of various combinations of the control agents. A treatment with Metarhizium spores resulted in wireworm mortalities of about 80%. Contrary to expectations, a combination of the EPF with the garlic extract did not increase, but slightly decrease wireworm mortality. The data gained from the image analysis revealed that the tunnelling activity of wireworms was clearly reduced in the presence of garlic, which, together with a reduced germination rate of spores, is a possible explanation for the antagonism detected in the combined treatment. The methodological approach developed here can be used to study the interactions among control agents and soil insects over several days and weeks.

O propósito do presente estudo foi aplicar as equações do modelo de potência crítica de dois e três parâmetros após a depleção de uma quantia fi xa de capacidade de trabalho anaeróbio (AWC), seguido de um período curto de repouso. Dezesseis sujeitos realizaram: (1) duas familiarizações ao exercício severo no cicloergômetro; (2) 4-5 exercícios máximos em dias diferentes para a estimativa da CP e AWC por meio dos modelos de dois e três parâmetros; (3) os mesmos procedimentos descritos no #2 foram realizados após 30 s de repouso e de um exercício de 180 s a uma intensidade em que a exaustão provavelmente ocorreria em ~300 s. A CP 2parameter (130-174 W versus 131-170 W) e CP 3parameter (108 versus 100 W) estimadas após o exercício prévio severo e seguido por um curto período de repouso permaneceu estável quando comparado às estimativas sem o exercício prévio. A AWC 2parameter foi diminuída em resposta ao exercício prévio severo. A AWC 3parameter não foi signifi cativamente reduzida. As correlações entre CP 2parameter derivados da mesma equação com e sem a redução prévia da AWC 2parameter foram fortes (r = 0,97-0,99; P < 0,001). Para a CP 3parameter a correlação foi somente moderada (r = 0,62; P = 0,01). Assim, pode ser concluído que o modelo de potência crítica de dois parâmetros promove descrições matemáticas coerentes quando é induzido um exercício prévio, sendo que a AWC 2parameter foi alterada enquanto que a estimativa da CP 2parameter permaneceu constante.

Small-scale Fishermen and Risk Preferences

Using an experimental approach, we investigate the risk preferences of artisanal fishermen in Tanzania waters of Lake Victoria. The experiment concerns pairwise comparisons of hypothetical fishing trips that vary in expected mean and spread of the net revenue. The results show that about 34% of the fishermen can be considered as risk neutral, 32% as risk averse, and 34% as risk seekers. Econometric analysis indicates that the likelihood of belonging to the risk-seeking group increases if motorboats are used, if fishing is the main source of household income, and if the fisherman is targeting Nile perch. Asset ownership and perhaps socioeconomic variables influence risk preferences.
Spectroscopic measurements of the electron temperature in low pressure radiofrequency Ar/H2/C2H2 and Ar/H2/CH4 plasmas used for the synthesis of nanocarbon structures

This paper deals with optical emission spectroscopy studies of low pressure (0.1–0.5 Torr) capacitively coupled radiofrequency hydrocarbon/argon-rich plasmas used for the synthesis of nanocarbon structures. The main goal of this paper is to obtain the electron temperature of such far-from-equilibrium plasmas as a function of the pressure, the excitation power and the argon content. In doing so, we have found that the argon upper energy levels used for electron temperature estimation remain close to corona balance. The latter has allowed us to use a modified Boltzmann plot technique to derive the electron temperature. It was found that, for the plasmas investigated, an increase of the argon population density (from 10% to 95%) leads to a pronounced decrease of the electron temperature while an increase of the processing pressure produces a moderate increase of the electron temperature. Additionally, the increase of the power from 50 to 300 W produces a very slight growth of the electron temperature.
Perceptions of organizational politics and organizational citizenship behavior: The moderating role of workplace friendship

The objective of this study is to investigate the relationship between workplace friendship, perceptions of organizational politics and organizational citizenship behavior in Pakistan’s public sector organizations. Data has been collected through structured questionnaire from 150 employees. The results of the study show a negative impact of perceptions of organizational politics on organizational citizenship behavior, while workplace friendship affects organizational citizenship behavior positively. The workplace friendship significantly moderates the relationship of perceptions of organizational politics and organizational citizenship behavior. The future research needs to test the relationship of perceptions of organizational politics with other organizational outcomes, and should collect the data from various types of organizations.

DesignCon 2004 Practical Multi-Gigahertz Clocks for ASIC and COT Designs

This TecForum begins by providing background on existing methods employed by full-custom designers for multi-gigahertz clocks. In addition, it explores in some detail the inductive nature of GHz clock networks. A novel clocking methodology termed "rotary clocking" will be proposed that provides: near zero skew; greatly reduced noise generation; insensitivity to process, voltage and temperature variations; and very significant power savings. The presenters provide evidence that this method would allow ASIC and COT designers to utilize far more of the available process performance, narrowing the gap to full-custom performance. The TecForum will conclude with a look at additional tools and techniques that need to be developed to fully automate this approach.
The evaluation of time variability of tidal parameters h and l using SLR technique

The estimated parameters h2 and l2 (Love and Shida numbers for second degree tides) are based on the analysis of the SLR data from the period 2013.1-2015.1. The solution has been computed using the LAGEOS-1 and LAGEOS-2 data. The analysis was conducted in two cases: separately and jointly for the two satellites. The results were compared with our previous work to see if there are some systematic differences and time evolution of the Love and Shida numbers. As the final adjusted values of the Love and Shida numbers were adopted parameters estimated for the common analysis based on data for LAGEOS-1 and LAGEOS-2. The new values of these parameters are equal to: h2 = 0.6140 ± 0.0005 and l2 = 0.0876 ± 0.0002. ARTICLE INFO
PD-ECO 2008 / 02 Inflation targeting works well in Latin America

This paper analyses the extent to which inflation targeting (IT) has improved macroeconomic performance in a group of Latin American countries during the period 2000-2005. In the first part we build a model to clarify some key features and expected results in emerging economies that have adopted the IT regime. In the empirical part we apply statistical tests with data from eighteen Latin American countries, and show that the five inflation targeters obtained both better short-term macroeconomic results and higher medium-term economic growth than the other Latin American countries in the sample.
Design, implementation and testing of a Modular Multilevel Converter

Abstract The Modular Multilevel Converter (MMC) is a power electronic structure used for high voltage adjustable speed drives applications as well as power transmission applications and high-voltage direct current. MMC structure presents many advantages such as modularity, the absence of a high voltage DC bus and very low switching frequency. It presents also some disadvantages such as modeling complexity and control due to the large number of semiconductors to control. The objectives of this paper are to present the methodology to design a laboratory MMC converter and its control system. This methodology is based on an intensive used of real-time simulation, to develop and test the control algorithm is proposed. This MMC prototype must be as realistic as possible to a full scale MMC, with a large number of sub-modules (i.e. 640 kV on the DC side, a rated power of 1 GW and 400 sub-modules). A control hardware integrating distributed processors (one for each arm) and a master control is presented. The protocols to validate sub-modules, arms and the converter are explained.

Implicit and explicit attitudes among students * Actitudes implícitas y explícitas en estudiantes

r e s u m e N Los procesos mentales y la experiencia mental no son la misma cosa. Los primeros son las operaciones de la mente, la otra es la vida subjetiva que emerge de dichas operaciones. En la evaluación social, las actitudes implícitas y explícitas expresan esta distinción. El sitio https://implicit.harvard. edu fue creado para ofrecer experiencia con la Prueba de Asociación Implícita (IAT por sus siglas en inglés), un procedimiento diseñado para medir el conocimiento social que puede operar por fuera de la conciencia. En este trabajo examinamos las relaciones entre el IAT y medidas explícitas. 143 estudiantes de la Universidad de Porto completaron medidas para este estudio. Los resultados muestran que: a) las preferencias implícitas son penetrantes, y b) las actitudes implícitas se relacionan débilmente.

INFLUENCE OF HYDROXYPROPYL-BETA-CYCLODEXTRIN ON THE PHYSICOCHEMICAL AND BIOLOGICAL CHARACTERISTICS OF A FLAVONE WITH IMPORTANT PHARMACOLOGICAL PROPERTIES

The purpose of this study was to investigate the influence of hydroxypropyl-β-cyclodextrin on diosmin, substance from the flavones category with important pharmacological properties. We carried out solubility studies, calculating the solubility constant of the complex formed between diosmin and hydroxypropyl-cyclodextrin at various temperatures (20, 25 and 37 0 C) and in the presence of increasing cyclodextrin concentrations. AL type curves were obtained which suggest the formation of an inclusion compound on a 1:1 molar ratio and the solubility constants had values between 370 and 453 M -1 . Knowing that between diosmin, hydroxypropyl-cyclodextrin and the used solvent, thermodynamic interactions occur, we investigated the influence of these interactions on several thermodynamic parameters such as Gibbs free energy change, free energy change, enthalpy change and entropy change. The calculated values showed that the reaction is positively influenced by the cyclodextrin’s concentration increment and the temperature, the process being spontaneously. Next, inclusion compounds were obtained by co-evaporation and co-precipitation, and their structures were confirmed by FTIR and MS analysis. The complexes were tested in vitro compared with the parent substances, the results indicating improved antioxidant and antimicrobial activities. Moreover, the dissolution of diosmin increased in mediums similar to physiological conditions (simulated gastric and intestinal).
Feasibility of using polypropylene ground cover upon consideration of long-term responses of sweet cherry nutrition and profitability

The impacts of synthetic polypropylene ground cover in the row area of sweet cherry (Prunus avium L.) trees (‘Regina’/’Gisela 6’) on soil nutrient availability, tree mineral nutrition and productivity, and economic returns were investigated on a Van Horn fine sandy loam soil at Hood River OR, from 2000 to 2007. Treatments included 2.44-m wide synthetic fabric ground cover made of black, woven poly-propylene over the row area of cherry trees (woven fabric), and no ground cover but with herbicide applications in the row area with the same width as the polypropylene ground cover (herbicide strip) – standard industry practice. This article reports the plant nutrition and soil fertility results of 2006 and 2007 and profitability and feasibility results of 2000 to 2007. Tree leaf nitrogen (N) concentrations were significantly higher with 9 to 14% increases using woven fabric compared with herbicide strip in 2006 and 2007. However, leaf sulfur (S) concentrations were significantly lowered with woven fabric in the two seasons. Woven fabric resulted in fruit with comparable quality and possible greater storability under enhanced fruit yields than herbicide strip in both years. Woven fabric was more profitable than herbicide strip based on an additional net present value of $2,606 ha-1 by the end of this study. Woven fabric had annual gross returns greater than annual costs in the fourth year after planting by $8,181 ha-1 relative to herbicide strip, and had cumulative net returns greater than total costs of all previous years in the sixth year after planting by $17,796 ha-1 over herbicide strip. However, to establish a sweet cherry orchard with woven fabric, the grower would spend an additional $4,332 ha-1 over herbicide strip. In conclusion, woven fabric is a profitable and sustainable in-row ground management alternative to herbicide strip for orchards from a long-term perspective.
Segmented mirror coarse phasing with white light interferometry: modeling and experimenting on NGST's Wavefront Control Testbed

A method of coarse phasing segmented mirrors using white light interferometry (WLI) has been developed for the Next Generation Space Telescope (NGST) wavefront sensing and control. Using the broadband point PSF of the segmented mirrors taken during a segment piston scan, the WLI can accurately detect small residual piston errors. WLI does not rely on extra optics and uses only the final imaging camera. With its high sensitivity to small segment piston error WLI can be used as a complementary phasing algorithm to the dispersed fringe sensor (DFS) for NGST. This paper will present the results from modeling and experiment on the NGST's Wavefront Control Testbed (WCT).
