Conversations and Perspectives on Peer Feedback for Problem Solving

Peer feedback has been suggested as an avenue to leverage students as partners in their own learning and assessment across many disciplines. However, successful implementation of peer feedback activities may prove challenging if students believe that feedback requires more objective expertise than they possess. Summarizing participant contributions and dialogue from a conversation cafe session at the 2018 University of Calgary Conference on Postsecondary Learning and Teaching, this paper explores and classifies the common themes in peer feedback in the context of literature on the subject. The most promising areas for future research and practitioner support in scientific problem-solving tasks are highlighted.
THE EFFECT OF THE WEB BASED ASYNCHRONOUS TEACHING METHOD COURSE ON THE PRE-SERVICE TEACHERS' ACHIEVEMENT, METACOGNITION, AND ATTITUDES TOWARDS COMPUTER, WWW AND WEB BASED COURSE

THE EFFECT OF THE ASYNCHRONOUS WEB BASED COURSE ON THE PRE-SERVICE TEACHERS’ ACHIEVEMENT, METACOGNITION, AND ATTITUDES TOWARDS COMPUTER, WWW AND WEB BASED COURSE Topcu, Abdullah Ph.D., Department of Secondary Science and Mathematics Education Supervisor: Assoc. Prof. Dr. Behiye UBUZ April 2005, 181 pages This study aimed to explore the effects of instructional methods in the asynchronous web-based “Science and Math Teaching Methods Course” on preservice teachers’ achievement, metacognition, and attitudes towards computer, WWW, and the web-based course. It was conducted with two groups, total of 63 third grade pre-service teachers, and one instructor (the researcher), in the Elementary Education Department at Bosphorus University in the academic year of 2003-2004. The Instructor used “Direct Instruction” method based on behaviorist approach for one group, and “Indirect Instruction” method based on constructivist approach for the other one. The general metacognition questionnaire and, attitude scales for the computer and WWW were given as pretests, and after a fourteen-week treatment period they were given as posttests to both groups. Additionally, in the middle of the semester a midterm exam, and at the end of the semester a final exam, and attitudes towards web-based course scale were administered. Thus, the effectiveness of the two different instructional methods was compared. The data obtained were analyzed by statistical techniques of multivariate analyses of covariance. Results of the statistical analyses indicated that the group
Fundamental Limits of Memory-Latency Tradeoff in Fog Radio Access Networks Under Arbitrary Demands

We consider a fog radio access network (F-RAN) with multiple transmitters and receivers, where each transmitter is connected to the cloud via a fronthaul link. Each network node has a finite cache, where it fills its cache with portions of the library files in the off-peak hours. In the delivery phase, receivers request each library files according to an arbitrary popularity distribution. The cloud and the transmitters are responsible for satisfying the requests. This paper aims to design content placement and coded delivery schemes for minimizing both the expected normalized delivery time (NDT) and the peak NDT which measures the transmission latency. We propose achievable transmission policies, and derive an information-theoretic bound on the expected NDT under uniform popularity distribution. The analytical results show that the proposed scheme is within a gap of 2.58 from the derived bound for both the expected NDT under uniform popularity distribution and the peak NDT. Next, we investigate the expected NDT under an arbitrary popularity distribution for an F-RAN with transmitter-side caches only. The achievable and information-theoretic bounds on the expected NDT are derived, where we analytically prove that our proposed scheme is optimal within a gap of two independent of the popularity distribution.
Subcortical, modality-specific pathways contribute to multisensory processing in humans

Oftentimes, we perceive our environment by integrating information across multiple senses. Recent studies suggest that such integration occurs at much earlier processing stages than once thought possible, including in thalamic nuclei and putatively unisensory cortical brain regions. Here, we used diffusion tensor imaging (DTI) and an audiovisual integration task to test the hypothesis that anatomical connections between sensory-related subcortical structures and sensory cortical areas govern multisensory processing in humans. Twenty-five subjects (mean age 22 years, 22 females) participated in the study. In line with our hypothesis, we show that estimated strength of white-matter connections between the first relay station in the auditory processing stream (the cochlear nucleus), the auditory thalamus, and primary auditory cortex predicted one’s ability to combine auditory and visual information in a visual search task. This finding supports a growing body of work that indicates that subcortical sensory pathways do not only feed forward unisensory information to the cortex, and suggests that anatomical brain connectivity contributes to multisensory processing ability in humans.
Effects of feeding dry fat and yeast culture on broiler chicken performance

A feeding trial with 400 male broilers (Ross) was conducted to investigate the effect of using dry fat and 2 levels of yeast culture (Saccharomyces cerevisiae) on performance, blood glucose, cholesterol, calcium, phosphorus, cobalt, copper, magnesium, manganese, and zinc. One-day-old broilers were distributed among 4 treatments, with 4 replicates and 25 chicks/replicate. The treatments were: diet 1 (basal diet with maize oil, group T1), diet 2 (basal diet with dry fat, group T2), diet 3 (basal diet with dry fat + 2 kg of yeast culture/t diet, group T3), and diet 4 (basal diet with dry fat + 3 kg of yeast culture/t diet, group T4). Measurements included body weight gain, feed intake and conversion, serum parameters, carcass weight, and abdominal fat. The inclusion of dry fat and 3 kg of yeast culture/t improved body weight gain and feed conversion (P < 0.05) compared with chicks from groups T2 and T3, but no differences were observed when compared with the control group. The serum cholesterol levels were significantly (P < 0.05) reduced by adding the yeast culture when compared with chicks from the control and T2 groups. Furthermore, the abdominal fat percentages were significantly lower in chicks from groups T1, T3, and T4 compared with that of group T2. The Co and Zn concentrations in the liver were significantly reduced (P < 0.001 and P < 0.05, respectively) by feeding of yeast culture, but no effect was observed for Cu, Mn, and Mg concentrations. In conclusion, the addition of yeast culture (3 kg/t) to diets containing dry fat improves broiler growth performance and positively affects the carcass characteristics by reducing the abdominal fat and blood cholesterol level.
Technical and Economic Evaluation of Hybrid wind/PV/Battery Systems for Off-Grid Areas using HOMER Software

Incremental consumption of electrical energy, reduction of fossil fuel resources and environmental pollution problems caused by them are the main reasons, which tend the managers and officials in countries energy sector to develop use of renewable systems. In the not-too-distant future the use of renewable energy such as wind and solar will be very important and will play predominant role in economic indices of power systems. In recent years, technological advances in renewable energy and increasing price of petroleum products promote system managers to use low-cost and low-emission energy resources in form of hybrid systems and widespread propagation of electricity generation have been developed in remote areas. In Hybrid systems two or more sources of renewable energy is typically adopted, which increases the reliability of these systems. In this paper, the technical and economical consideration of a wind and solar hybrid system to supply electrical energy for a number of remote users (aid and medical emergency Shelter in Yazd) is provided. In order to investigate optimization and economic analysis of the proposed hybrid system, the HOMER software is used. The results of Simulation in HOMER software show that Solar cells and wind systems with average generation power of 896 kWh/yr. and 343 kWh/yr. , consist proportion of 72 and 28 percent of the total generated energy respectively, which are dedicated to satisfy the loads Full Text: PDF DOI: http://dx.doi. org/10.11591/ijpeds.v7. i1.pp134-143
Contextually-Based Social Attention Diverges across Covert and Overt Measures

Humans spontaneously attend to social cues like faces and eyes. However, recent data show that this behavior is significantly weakened when visual content, such as luminance and configuration of internal features, as well as visual context, such as background and facial expression, are controlled. Here, we investigated attentional biasing elicited in response to information presented within appropriate background contexts. Using a dot-probe task, participants were presented with a face–house cue pair, with a person sitting in a room and a house positioned within a picture hanging on a wall. A response target occurred at the previous location of the eyes, mouth, top of the house, or bottom of the house. Experiment 1 measured covert attention by assessing manual responses while participants maintained central fixation. Experiment 2 measured overt attention by assessing eye movements using an eye tracker. The data from both experiments indicated no evidence of spontaneous attentional biasing towards faces or facial features in manual responses; however, an infrequent, though reliable, overt bias towards the eyes of faces emerged. Together, these findings suggest that contextually-based social information does not determine spontaneous social attentional biasing in manual measures, although it may act to facilitate oculomotor behavior.
Stable carbon isotope analysis on fossil Cedrus pollen shows summer aridification in Morocco during the last 5000 years

Quantitative climate reconstructions from pollen typically rely on empirical relationships between pollen abundances or assemblages and climate, such as the modern analogue technique. However, these techniques may be problematic when applied to fossil sequences, as they cannot separate anthropogenic from climatic influence on pollen assemblages. Here, we reconstruct Mid‐ to Late Holocene summer aridity in the Middle Atlas, Morocco, using stable carbon isotope analysis of isolated fossil Cedrus pollen. This approach is based on well‐documented plant physiological responses to moisture stress and is therefore independent of vegetation composition. We find that there has been a general long‐term trend of increasing summer aridity in the region during the last 5000 years to the present day. The gradual decline of Cedrus atlantica forest in the Late Holocene follows this aridity trend. Additionally, we show how isolating a specific pollen type for carbon isotope analysis yields a robust climate signal, versus using pollen concentrates or bulk sediment. Our findings indicate that climate has become drier in the region and confirms the Mid‐ to Late Holocene aridification trend observed more widely in the western Mediterranean, using a novel proxy for this region with good potential for wider application in other environments.
Verification of Effectiveness of an MRF Semi-Active Damper using a Double-Cage Structure Elevator Simulator

Several safety devices are installed in elevators to protect passengers. An emergency-stop-device is a safety device that operates during emergencies such as the breaking of wires. This device stops the elevator immediately, and as a result, generates an excessive impact force on the passengers that has a risk of injury to passengers Therefore, we propose a new elevator system equipped with a magneto-rheological fluid (MRF) semi-active damper and a spring in the double-cage structure elevators currently used to absorb this impact force. In a previous study, we verified the effectiveness of the proposed system by realising a digital simulation. Therefore, in this study, we verify the effectiveness of the proposed system by conducting experiments using a small emergency stop simulation apparatus and evaluate it based on safety standards.
Usefulness of Apparent Diffusion Coefficient Value of Diffusion-Weighted Imaging and Peak Standardized Uptake Values of Positron Emission Tomography-CT for Predicting Prognostic Factors of Breast Cancer

Purpose This study was performed to retrospectively correlate the apparent diffusion coefficient (ADC) value and peak standardized uptake value (pSUV) with prognostic factors and MRI findings for breast lesions. Materials and Methods Ninety four breast cancers in 82 women were included in this study. Our patients underwent presurgical MRI including diffusion-weighted imaging (DWI), 18-fluoro-deoxyglucose PET-CT, and immunohistological staining of the surgical or biopsy specimens. We evaluated relationships between mean ADCs and pSUVs with a variety of prognostic factors (age, tumor size, histologic grade of tumor, hormone receptors, human epidermal growth factor receptor 2 expression status, and nodal metastasis) and MRI findings (shape, margin and internal enhancement of mass, T2-signal intensity, and kinetics), using statistical methods. Results Both mean ADCs and pSUVs were significantly associated with histologic grade (p = 0.000 and p = 0.001) and nodal metastasis (p = 0.013 and p = 0.001). pSUVs were significantly associated with tumor size and estrogen receptor status, as well as irregular shape and rim enhancement pattern on MRI findings. On multivariate analysis, mean ADCs were significantly associated with invasiveness, estrogen receptor status and HER-2 expression status. PSUVs were only significantly associated with tumor size. Conclusion Mean pSUVs on PET-CT and ADCs on DWI helped predict prognosis of breast cancer.
Psychological Underpinnings of the Work-Site Selection Process of Knowledge Workers

ABSTRACT As a result of technological advances, knowledge workers have become increasingly mobile; people can perform work in a variety of new locations via an assortment of new working arrangements. Knowledge workers are now faced with the question of where to work. We argue that the process of work-site selection depends on the relationship between a variety of individual factors such as motivation, cognitive and affective evaluation, and regulatory focus as they interact with self-regulatory resources. Specifically, we use a dynamic interactionist perspective to integrate components of social exchange, self-determination, regulatory focus, and self-regulation theories. The resulting conceptual model contributes to the existing literature by integrating different theoretical sets of predictor variables and examining their effect on self-regulatory resources, which have implications for productivity and well-being. We discuss implications and avenues for future work exploring these relationships.
Sexual dimorphism and left-right asymmetry of carapace ornamentation in Hemicytheria setosa RUNDIĆ 2002

In biostratigraphic research of the Upper Miocene of Pannonian basin system, one of the frequently detected and important ostracod genera is Hemicytheria POKORNÝ (1955). Among more than 20 species of this genus, Hemicytheria setosa is present in sandy facies of the Lake Pannon sediments in Serbia and Bosnia and Herzegovina. The aims of this study were to describe sexual dimorphism and differences between left and right valve morphology in Hemicytheria setosa. Landmark based geometric morphometrics is applied on the grounds of existence of the homologue pattern of the fossae and pore conuli on the valve surface of this group of ostracods. Significant differences between sexes and between left and right valves are detected in the present study. The obtained results indicate that applied methods and chosen landmarks could be useful in the studies of valve ornamentation-variation in fossil and recent Ostracoda.
Disentangling Normative and Informational Influence in Group Decision Making

Author(s): Garcia, Robert Jaffe | Advisor(s): Scurich, Nicholas | Abstract: Although extensive social psychological research has examined conformity for individualized behaviors, no laboratory research has experimentally manipulated conformity in the context of group decisions. Normative conformity is motivated by the desire for social acceptance while informational conformity entails looking to others for correct answers. Using the applied context of a jury deliberation, the present studies aimed to disentangle the relative effects of normative and informational conformity by comparing participants’ votes and ratings of evidence convincingness before and after exposure to a confederate group’s opinions during a poll. Private polls were intended to shield jurors from normative influence, while public polls invited conformity via both normative and informational influence. Results showed disagreement with the group majority during the first poll was a consistently strong predictor of vote switching, but no significant differences emerged in vote switching between public and private deliberation. Changes in beliefs about the strength of the evidence against the defendant partially mediated the effect of a disagreeing majority on vote switching. For participants who initially voted guilty, changes in beliefs drove a greater proportion of conformist vote switching in public deliberations than in private deliberations. This finding suggests that people may weigh public comments in group decisions more heavily or that the pressure to conform in public deliberation may increase susceptibility to belief change. More generally, it also suggests that normative pressure may sometimes fuel informational influence, and that the two constructs may be more linked than previously conceptualized. Implications are discussed for extant research on the intersection between conformity and group decision making and for jury protocol.
Inherent Safety Assessment of Solvent Alternatives for Palm Oil Recovery

Solvent extraction is a method implemented with the purpose to recover the remaining oil in spent bleaching earth. n-hexane is the most commonly used solvent in solvent extraction due to its advantages such as able to easily extract the oil and can be separated easily with low chances to form emulsions during the extraction process. Although n-hexane is a good solvent for extraction, n-hexane can easily vaporise to the surroundings due to its volatility making it a threat to human health and environment due to its high toxicity and high flammability characteristics. N-hexane should be replaced with greener solvents in term of safety and environmental impacts. This paper aims to evaluate the inherent safety of the solvents designed by the previous work involving three new solvents which are cyclohexane, 2-pentanone and isopropyl acetate and compare it with the existing solvent which is n-hexane. The inherent safety assessment of these solvent were done using the Numerical Descriptive Inherent Safety (NuDIST) technique. In this technique, scores are assigned to each solvent according to their inherent safety level in term of three parameters. The parameters involved are flammability, explosiveness and toxicity. In NuDIST, higher scores indicate higher hazard and is not preferable compared to lower scores. According to the assessment done, cyclohexane is the least hazardous solvent with CSTS of 191.53 while n-hexane is evaluated as the most hazardous solvent with CSTS of 198.32. Inherent safety assessment done between cyclohexane and n-hexane using the NuDIST method indicates cyclohexane as the inherently safer choice than n-hexane. This further supports the result produced by the previous work which indicates cyclohexane as having more promising properties as a solvent in order to extract palm oil in spent bleaching earth compared to n-hexane.

The effects of different entry modes of foreign direct investment on labor rights in the developing world

abstract Although many studies have investigated the effects of foreign direct investment on labor rights in the developing world, no studies of which we are aware have considered how differences in the mode of entry—that is, mergers and acquisitions (M&As), cross-border joint ventures (JVs), and greenfield investments (GIs)—taken by multinational corporations affect labor rights in host countries. Using panel data for up to 113 developing countries from 1985–2002, we find that foreign firms that enter via M&As tend to have minimal, or slightly negative, effects on labor rights, whereas JVs and GIs support improvements in workers’ rights. Overall, the results suggest that the sectors and motivations associated with JV and GI modes of entry increase labor demand, improving the bargaining power of workers.
Race, Gender, and Disability and the Risk for Juvenile Justice Contact

Exclusionary school discipline has received national attention due to its association with juvenile justice contact. Research has demonstrated support for links between exclusionary discipline and negative outcomes such as school dropout and juvenile justice involvement. The purpose of this study was to examine the intersections of race, gender, and disability in explaining the risk for juvenile justice contact using a state database, representing a sample of adolescent students. Controlling for individual, school, and community characteristics that are associated with juvenile justice contact such as, race/ethnicity, previous years’ discipline rate, student retention from previous year, primary disability, whether the campus is a Title I school, as well as student body size and diversity, results suggest that disproportionality is prevalent when examining juvenile justice contacts, but the relationship among race, gender, disability, and discipline is a complicated one. Implications for understanding juvenile justice contact outcomes and future research for advancing the field are discussed.
