Examination of Eating Attitudes in Terms of Interpersonal Relationships and Life Satisfaction in Late Adolescence

The aim of the study was to analyze the relationship between eating attitudes and interpersonal relationship and life satisfaction by late adolescents. A total of 511 students, 362 females and 149 males, studying in different departments of Faculty of Educations, Recep Tayyip Erdogan University, On Dokuz MayA½s University, Karadeniz Technical University and Ahi Evran University, participated. Sociodemgraphic Form, Eating Attitude Test, Interpersonal Relations Scale and Life Satisfaction Scale and were used as instruments. Data analysis was performed using SPSS 23.00 software. Descriptive and inferential statistical techniques, Pearson product-moment correlation coefficient, Multilinear Regression analysis and the independent groups t-test were used. Findings revelaled that a significant positive correlation was determined between eating attitudes and nourishing and inhibitory relationship styles. No statistically significant correlation was determined between eating attitudes and life satisfaction. Besides, interpersonal relationship account for 3% of total variance. Eating attitudes not differed according to gender is among the study results. The research reached the conclusion that interpersonal relationship styles contributed to the explanation of eating attitudes, while life satisfaction had no contribution to the explanation of eating attitude. Additionally another result of the research is that there was no difference between eating attitudes of males and females.
Food leftovers in workplace cafeterias: an investigation of beliefs and psychosocial factors

Reducing food waste is a major challenge in achieving a more sustainable food system. This research analyzes the psychosocial factors and cognitions that determine actual food waste behaviors in mass catering services. 216 customers of a French worksite cafeteria completed an online questionnaire based on the theory of planned behavior extended to moral norms. Over a period of four days, the quantity of food left by each respondent was weighed and linked to the answers. Findings indicate that food waste behaviors in mass catering setting are mainly drive by perceived behavioral control. Analysis of the underlying control beliefs suggests that interventions should focus on two specific aspects: improving food quality and making portion sizes more flexible.
Conceptual change in natural resource management students’ ecological literacy

Abstract Conceptual change in undergraduate capstone courses provides unique opportunities to examine how students draw from multiple courses and experiences to resolve conceptual confusion. We examined how senior-level natural resource management students revised their conceptions of ‘ecosystem’ throughout their capstone course. The concept of ecosystem is complicated by a lack of shared meaning across disciplines. Our grounded theory study analyzed student coursework and pre/post interviews. It was informed by socio-cultural and conceptual change theories and used an ecological literacy metric to examine how students’ conceptualizations of the relationships between natural, ecosystem, human, and human artifact influenced their conceptions of ecosystems. Students who did not describe ecosystems as natural struggled less with integrating human society into ecosystems than their peers that did. We conclude that it is important to explicitly create shared meaning of key conceptions at the start of a capstone course to facilitate shared meaning-making and desired conceptual change during the course.

The AOF Method for Production, Use, and Management of Instructional Media

Automatic recording and capturing of live lectures and presentations has been explored and evaluated by various research projects since the mid 90s and has meanwhile been adapted by a number of commercial systems. Here, we discuss and summarize “Authoring on the Fly” (AOF) which is a special incarnation of this idea. The purpose of this paper is to give an overview of the AOF approach, the experience we have obtained and the requirements we have identified during its development over the last few years as well as to report on current and future research issues involved.
Towards a process model of information systems implementation: the case of customer relationship management (CRM)

The failure rate of Customer Relationship Management (CRM) implementations is estimated to be greater than 65%. Lowering the failure rate and supporting the success of information systems (IS) are the ultimate goals of IS practitioners and researchers. However, most previous research in the area has focused on identifying factors such as critical success factors (CSFs) that are correlated with IS success. There has been little research on how IS implementation may lead to successful results. The state of knowledge in IS implementation may be likened to cooking with a list of ingredients but not the recipe. Drawing on process theory, this study examines the process of IS implementation by explaining how factors of IS implementation influence each other and how interactions among them produce results. Based on one successful case and two unsuccessful cases, we develop the process model of IS implementation, by which the process of IS implementation and the dynamics of IS success can be explained. The proposed model facilitates an understanding of how repeating patterns of IS failure can be reversed, and could serve to guide new IS implementation projects.
The Structure of Corporate Holdings and Corporate Governance: Evidence from India

This paper examines how the structure of corporate holdings impacts upon the corporate governance mechanisms and outcomes. Using a panel data of 500 large listed Indian â€¦firms we compare â€¦firms with dispersed equity ownership, and business group â€¦firms with cross-holdings and concentrated family ownership, within the same institutional frameworks. Contrary to the popular hypothesis that concentrated shareholding leads to worse corporate governance outcomes, we find that the corporate governance outcomes are similar for both types of â€¦firms, even though the incentive alignment mechanisms may be different. The results of this paper suggest that corporate holding structures and governance mechanisms adjusts to optimize value and performance.
Combining Time-Of-Flight depth and stereo images without accurate extrinsic calibration

We combine a low resolution Time-Of-Flight (TOF) depth image camera based on Photonic Mixer Devices with two standard cameras in a stereo configuration. We show that this approach is useful even without accurate calibration. In a graph cut approach, we use depth information from the low resolution TOF camera to initialise the domain, and colour information for accurate depth discontinuities in the high resolution depth image. The system is promising as it is low cost, and naturally extends to the setting of dynamic scenes, providing high frame rates.
The fibronectin cell attachment sequence Arg-Gly-Asp-Ser promotes focal contact formation during early fibroblast attachment and spreading

Cultured fibroblasts form focal contacts (FCs) associated with actin microfilament bundles (MFBs) during attachment and spreading on serum- or fibronectin (FN)-coated substrates. To determine if the minimum cellular adhesion receptor recognition signal Arg-Gly-Asp-Ser (RGDS) is sufficient to promote FC and MFB formation, rat (NRK), hamster (Nil 8), and mouse (Balb/c 3T3) fibroblasts in serum-free media were plated on substrates derivatized with small synthetic peptides containing RGDS. These cultures were studied with interference reflection microscopy to detect FCs, Normarski optics to identify MFBs, and immunofluorescence microscopy to observe endogenous FN fiber formation. By 1 h, 72-78% of the NRK and Nil 8 cells plated on RGDS-containing peptide had focal contacts without accompanying FN fibers, while these fibroblasts lacked FCs on control peptide. This early FC formation was followed by the appearance of coincident MFBs and colinear FN fibers forming fibronexuses at 4 h. NRK and Nil 8 cultures on substrates coated with native FN or 75,000-D FN-cell binding fragment showed similar kinetics of FC and MFB formation. In contrast, the Balb/c 3T3 mouse fibroblasts plated on Gly-Arg-Gly-Asp-Ser peptide-derivatized substrates, or on coverslips coated with 75,000-D FN cell-binding fragment, were defective in FC formation. These results demonstrate that the apparent binding of substrate-linked RGDS sequences to cell surface adhesion receptors is sufficient to promote early focal contact formation followed by the appearance of fibronexuses in some, but not all, fibroblast lines.
Do clinical features relate to theory of mind, empathy and 2D:4D in schizophrenia?

ABSTRACT OBJECTIVE: Digit ratios may be accepted as an indicator of level of prenatal androgen exposure during the fetal developmental period. Female-typical digit ratios have been suggested to be associated with better mentalizing and empathic abilities in general population. Recently, a number of studies have investigated the ratio of hand’s second and fourth digit fingers (2D:4D) in schizophrenia. The aim of this study was to investigate the hypothesis that positive symptoms are related to female-biased 2D:4D and relatively less impaired social cognition in schizophrenia, negative dimension is related to male-biased 2D:4D ratio and more pronounced deficits in social cognition. METHOD: The study was carried out in 48 patients with schizophrenia and 48 healthy controls. Patients were evaluated by Positive and Negative Syndrome Scale (PANSS). A digital caliper was used to measure 2D:4D finger lengths and social cognitive abilities were assessed using the Empathy Quotient (EQ) test and Reading Mind in the Eyes Test (RMET). RESULTS: Patients with schizophrenia had increased left 2D:4D finger lengths and showed poor theory of mind (ToM) and empathic abilities compared to healthy controls (p < 0.05). It was found that negative symptoms but not male-biased 2D:4D ratio were significantly associated with impaired RMET performance (p < 0.05). CONCLUSION: The present study indicates that negative dimension is negatively related to the severity of deficits in social cognition in schizophrenia. There was no evidence for a significant effect of sexual dimorphism as measured by digit ratio on social cognition and symptoms in schizophrenia.
High-throughput coherence controllers

Recent research shows that the occupancy of the coherence controllers is a major performance bottleneck for distributed cache coherent shared memory multiprocessors. In this paper we study three approaches to alleviating this problem in hardwired coherence controllers, namely, multiple protocol engines, pipelined protocol engines, and split request-response streams. Split request-response streams is an innovative contribution of this paper. The performance of pipelining in the context of coherence controllers has not been presented in the literature. Multiple protocol engines has not been studied in the context of hardwired controllers except for a study of ours and only to a limited extent. Using both commercial and scientific benchmarks on detailed simulation models, we present experimental results that show that each mechanism is highly effective at reducing controller occupancy by as much as 66% and improving execution time by as much as 51%, for applications with high communication bandwidth requirement. A combination of mechanisms further reduces controller occupancy and execution time by as much as 78% and 61%, respectively. Our results show that applying any of the parallel mechanisms in the coherence controllers allows integrating four times as many processors per coherence controller, thus reducing system cost, while maintaining or even exceeding the performance of systems with larger number of coherence controllers.
Influence of sedimentation on convective Instabilities in colloidal Suspensions

We investigate theoretically the bifurcation scenario for colloidal suspensions subject to a vertical temperature gradient taking into account the effect of sedimentation. In contrast to molecular binary mixtures, here the thermal relaxation time is much shorter than that for concentration fluctuations. This allows for differently prepared ground states, where a concentration profile due to sedimentation and/or the Soret effect has been established or not. This gives rise to different linear instability behaviors, which are manifest in the temporal evolution into the final, generally stationary convective state. In a certain range, above a rather high barometric number there is a coexistence between the quiescent state and the stationary convective one, allowing for a hysteretic scenario.
A case study on exploration of last-level cache for energy reduction in DDR3 DRAM

This paper studies the effects of last-level cache on DRAM energy consumption. In particular, we explore how different last-level cache configurations affect the idle periods of DRAM, and whether those idle periods can be exploited through the use of self refresh power down mode to enable maximum energy reduction in both the energy consumption of the last-level cache and DRAM. A suitable last-level cache configuration reduces active power consumption of DRAM by reducing read/write accesses to it and use of the self refresh power down mode reduces background power of DRAM, creating a possibility of significant energy reduction. We propose a power mode controller to adaptively transition DRAM to self refresh power down mode when a memory request hits the last-level cache, and activate the DRAM when a memory request misses the last-level cache. We experimented with eight applications from mediabench, and found that an optimal last-level cache configuration with self refresh power down mode can save up to 89% energy compared to a standard memory controller. Additionally, the use of self refresh power down mode degraded the performance by a maximum of 2% only. Thus, we conclude that exploration and optimization of last-level cache can result in significant energy savings for memory subsystem with little performance degradation.
Decomposing Random Mechanisms

Random mechanisms have been used in real-life situations for reasons such as fairness. Voting and matching are two examples of such situations. We investigate whether the desirable properties of a random mechanism survive decomposition of the mechanism as a lottery over deterministic mechanisms that also hold such properties. To this end, we represent properties of mechanisms–such as ordinal strategy-proofness or individual rationality–using linear constraints. Using the theory of totally unimodular matrices from combinatorial integer programming, we show that total unimodularity is a sufficient condition for the decomposability of linear constraints on random mechanisms. As two illustrative examples we show that individual rationality is totally unimodular in general, and that strategy-proofness is totally unimodular in some individual choice models. We also introduce a second, more constructive approach to decomposition problems, and prove that feasibility, strategy-proofness, and unanimity, with and without anonymity, are decomposable in non-dictatorial single-peaked voting domains. Just importantly, we establish that strategy-proofness is not decomposable in some natural problems.
MicroWave: a Generic Framework for Micro Simulation Based ex ante Policy Evaluation

This paper presents the MicroWave approach that has been developed to improve the process of modeling in the context of micro simulation. It leads to a more efficient model development, better quality of models and their output and improvement in knowledge management. A conceptual framework has been developed and translated into a hierarchical structure of GAMS program code. Besides, several software applications and other tools have been developed for support. These products are presented and some examples illustrate how MicroWave can be applied. MicroWave is especially useful in interdisciplinary research in which different persons are involved in the modeling process and when different models have to be combined.
Deep Extragalactic VLBI-Optical Survey (DEVOS) - I. Pilot MERLIN and VLBI observations

We present the results of the pilot observations of the Deep Extragalactic VLBI-Optical Survey (DEVOS). Our ultimate aim is to collect information on compact structures in a large sample of cxtragalaclic radio sources (∼10 4 objects) up to two orders of magnitude fainter than those studied in typical imaging Very Long Baseline Interferometry (VLBI) surveys up until now. This would lead to an unprecedented data base for various astrophysical, astrometric and cosmological studies. The first global VLBI observations of the DEVOS programme were successfully conducted in May 2002. We selected sources without any spectral criterion from the Very Large Array (VLA) Faint Images of the Radio Sky at Twenty-centimeters (FIRST) catalogue. that are also detected with the Multi-Element Radio Linked Interferometer Network (MERLIN). The DEVOS pilot sample sources are in the area of the sky that is covered hy the Sloan Digital Sky Survey (SDSS). We describe the sample selection and present high resolution 5-GHz radio images of the sources. Based on the results of this pilot study, we estimate the outcome of and the resources needed for a full-scale DEVOS project.
- 1-Testing a Communications Driver for the IEEE 1394 High Speed Serial Bus Standard

Software testing is a difficult and tedious task. For a network driver, software testing is still more laborious. The main reason for this is that a communications driver does not act as a stand-alone application used by an end user. A communications driver acts as a part of the operating system kernel and is used by other operating system components and/or applications through a general purpose Application Programming Interface (API). This paper discusses the experience that has been gained by testing a communications driver that provided a general purpose API to both kernel and user mode components. The driver was implemented on the Windows NT 4.0 and Windows 98 operating systems, and its underlying medium was an IEEE 1394 network.
Rapid updating for path-planning using nonlinear branch-and-bound

This paper develops and tests a novel rapid updating technique for use with a nonlinear branch and bound optimisation method, tailored for finding optimal trajectories for a vehicle constrained to avoid fixed obstacles. The key feature of the rapid updating technique developed is the ability to increment and re-arrange the existing search tree reducing the amount of computation taken to find a new plan. The rapid updating techniques developed are combined into a receding horizon control and compared to full cold start method. The rapid updating technique demonstrated an average 62% solve time improvement over a cold start. The rapid updating method is also demonstrated for removal of obstacles from the environment and very large scale problems with 60 obstacles.
Distributed AAA: Proposals for Ad Hoc Networks

AAA frameworks such as diameter protocol allows applications to define their own authentication and authorization mechanisms while the base protocol takes care of general accounting. This framework has been used by a couple of applications such as network access server application and mobile IP application. Both these applications have at least one thing in common: access to the fixed network infrastructure. Networks with fixed infrastructure can afford to dedicate a network element for AAA. Implementing AAA functionality in ad hoc networks is a different challenge. The main reason is the lack of fixed infrastructure. In an ad hoc network, the terminal devices themselves become the infrastructure and this infrastructure is not fixed. In this paper, we explore some options of using AAA in ad hoc networks. The proposals presented here are still at conceptual level and require more work to make them feasible.
Annals of Optimization Strategic Workforce Optimization : Ensuring Workforce Readiness with OptForce

Strategic workforce planning (SWP) has been identified as a top business challenge and a high priority in order to produce organizations that are capable of performing more effectively. Industry leaders recognize that success depends on attracting, retaining and developing talent, and having the right talent in the right place at the right time – to achieve the condition often characterized as workforce readiness. High readiness levels require anticipating and responding to changing workforce needs and market demands, and allocating resources effectively. We have approached the SWP challenge by applying state-of-the-art technology from decision sciences and advanced analytics to the field of talent management. Our resulting software, called OptForce, enables organizations to optimize workforce readiness and composition while accounting for critical workforce constraints. OptForce offers a broad range of predictive analytics capabilities including sophisticated workforce demand planning, fine-grained employee retention models, and agent-based simulation forecasting. Cloud hosted, the system additionally provides a prescriptive analytics capability through its simulation optimization engine.
Asset and Liability Management - The Institutional Approach to ALM by Commercial Banks in Poland: A Special Focus on Risk Management

According to the early evidence, privatization and consolidation of banks have a strong favorable impact on the advancement of ALM and risk management methods. This paper examines various approaches to ALM by commercial banks in Poland. It elaborates results of the empirical survey of ALM and risk management techniques applied by banks in Poland. The survey was conducted in Spring 1999. The analysis shows that privatization of banks contributes to the improvement of efficiency and to better risk management. It creates a favorable climate for implementation of more advanced risk management and measurement techniques. The size of the Polish private banks has also a positive effect on diverse methodology and sophistication of risk management. The analysis implies the need for a further consolidation of Polish financial institutions. Therefore, this paper reinforces arguments in support of accelerated privatization and consolidation of the Polish banking system.
The mediating effect of work–life balance on the relationship between work–family conflict and life satisfaction

The first purpose of this study was to develop a scale of work–life balance for Turkish working women and men. The second purpose was to investigate the mediating effect of work–life balance between work–family conflict, family–work conflict, and life satisfaction. In Study 1 (N = 274), a work–life balance scale was developed and initial validity evidence was presented. In Study 2 (N = 356), confirmatory factor analyses supported the scale’s unidimensionality. Cronbach’s alpha and the composite reliability for internal consistency were . 92. All studies indicated that the Work–Life Balance Scale was valid and reliable for a Turkish employee sample. Structural equation modeling supported indirect effects of work–family conflict and family–work conflict on life satisfaction via work–life balance. Multi-group analysis showed that the structural paths of the full model did not differ by gender.
