Limits to non‐state market regulation: A qualitative comparative analysis of the international sport footwear industry and the Fair Labor Association
Authors: Marx Axel 
Published: May 2008

AbstractNon‐state market regulation has become a central focus and continues to receive scholarly attention. The present paper provides an assessment of the conditions under which multinational firms join a multi‐stakeholder certification initiative. The cases of the Fair labor Association and 17 international sport footwear companies have been selected for this purpose. A Qualitative Comparative Analysis of the 17 cases is performed. The paper argues that the combination of sustained NGO pressure and public ownership of a firm is a necessary precondition for firms joining a multi‐stakeholder certification initiative. The theoretical and policy implications of this result are discussed.
Geology and Re‐Os Geochronology of Mineralization of the Miduk Porphyry Copper Deposit, Iran
Authors: Taghipour Nader , Aftabi Alijan , Mathur Ryan 
Published: May 2008

AbstractThe Miduk porphyry copper deposit is located in Kerman province, 85 km northwest of the Sar Cheshmeh porphyry copper deposit, Iran. The deposit is hosted by Eocene volcanic rocks of andesitic–basaltic composition. The porphyry‐type mineralization is associated with two Miocene calc‐alkaline intrusive phases (P1 and P2, respectively). Five hypogene alteration zones are distinguished at the Miduk deposit, including magnetite‐rich potassic, potassic, potassic–phyllic, phyllic and propylitic. Mineralization occurs as stockwork, dissemination and nine generations (magnetite, quartz–magnetite, barren quartz, quartz‐magnetite‐chalcopyrite‐anhydrite, chalcopyrite–anhydrite, quartz‐chalcopyrite‐anhydrite‐pyrite, quartz‐molybdenite‐anhydrite ± chalcopyrite ± magnetite, pyrite, and quartz‐pyrite‐anhydrite ± sericite) of veinlets and veins. Early stages of mineralization consist of magnetite rich veins in the deepest part of the deposit and the main stage of mineralization contains chalcopyrite, magnetite and anhydrite in the potassic zone. The high intensity of mineralization is associated with P2 porphyry (Miduk porphyry). Based on petrography, mineralogy, alteration halos and geochemistry, the Miduk porphyry copper deposit is similar to those of continental arc setting porphyry copper deposits. The Re‐Os molybdenite dates provide the timing of sulfide mineralization at 12.23 ± 0.07 Ma, coincident with U/Pb zircon ages of the P2 porphyry. This evidence indicates a direct genetic relationship between the Miduk porphyry stock and molybdenite mineralization. The Re‐Os age of the Miduk deposit marks the main stage of magmatism and porphyry copper formation in the Central Iranian volcano‐plutonic belt.
Evaluating Thickness of Bauxite Deposit Using Indicator Geostatistics and Fuzzy Estimation
Authors: Dag Ahmet , Mert Bayram A. 
Published: May 2008

AbstractEvaluating the geological properties of a mineral deposit is a fundamental task for mine planning and it requires an assessment of reserve parameters such as thickness and grade. This paper presents a linguistic model for estimating bauxite thickness within a deposit in a fuzzy environment using indicator geostatistics and fuzzy modeling. The proposed model consists of two main stages: determining the orebody boundary and estimating the thickness. In order to estimate the thickness, a rule‐based fuzzy inference mechanism has been developed based on data statistics. Results and performance of the model have been compared with that of a well‐known conventional technique, geostatistics (kriging), and it is shown that the proposed model has bigger estimation power. In addition, the fuzzy approach is more flexible than the kriging approach. The fuzzy methodology used in the present paper is convenient for modeling reserve parameters.
INNOVATION MANAGEMENT AND ECONOMIC PERSPECTIVES: THE CASE OF GREECE
Authors: HATZIKIAN YANNIS , BOURIS JOHN 
Published: May 2008

The level of the Greek economic growth is highly depended on three vital factors: a) entrepreneurship and business development b) innovation and creativity c) education and skills.The correlation among these factors are direct and clear. This is why it is so important to monitor economic growth in respects of innovation, education and business development and to pursue a methodical policy to stimulate and reinforce them.In this paper we focus on analysing the factors which affect the process of innovation in Greece in comparison with member states of European Union. More specific we attempt to measure innovation in Greek enterprises for the last decade and identify barriers to innovation in Greece as compared to other EU countries. We also evaluate the statistical relationship between per capita GDP (as a proxy to level of Greek people prosperity) and Research & Technological Development (RTD) Expenditure (as indicator to innovation-creativity activity) using Linear and Exponential Regression Models.In the knowledge-driven economy, economic growth was achieved mainly through innovation, technology diffusion and new product applications. Therefore, we probe deep into considerations which influence -either positively or negatively - the advancement of the innovation activity, through empirical evidence and statistical methodology. Since, innovation and Research & Technological Development (RTD) are often considered as a main drive for economic development, recommendations proposed in this article become more intense and must be incorporated in the industrial infrastructure and in management attitudes at national and regional level.
Superior Temporal Sulcus—It's My Area: Or Is It?
Authors: Hein Grit , Knight Robert T. 
Published: May 2008

Abstract
The superior temporal sulcus (STS) is the chameleon of the human brain. Several research areas claim the STS as the host brain region for their particular behavior of interest. Some see it as one of the core structures for theory of mind. For others, it is the main region for audiovisual integration. It plays an important role in biological motion perception, but is also claimed to be essential for speech processing and processing of faces. We review the foci of activations in the STS from multiple functional magnetic resonance imaging studies, focusing on theory of mind, audiovisual integration, motion processing, speech processing, and face processing. The results indicate a differentiation of the STS region in an anterior portion, mainly involved in speech processing, and a posterior portion recruited by cognitive demands of all these different research areas. The latter finding argues against a strict functional subdivision of the STS. In line with anatomical evidence from tracer studies, we propose that the function of the STS varies depending on the nature of network coactivations with different regions in the frontal cortex and medial-temporal lobe. This view is more in keeping with the notion that the same brain region can support different cognitive operations depending on task-dependent network connections, emphasizing the role of network connectivity analysis in neuroimaging.
Visual Processing Affects the Neural Basis of Auditory Discrimination
Authors: Kislyuk Daniel S. , Möttönen Riikka , Sams Mikko 
Published: May 2008

Abstract
The interaction between auditory and visual speech streams is a seamless and surprisingly effective process. An intriguing example is the “McGurk effect”: The acoustic syllable /ba/ presented simultaneously with a mouth articulating /ga/ is typically heard as /da/ [McGurk, H., & MacDonald, J. Hearing lips and seeing voices. Nature, 264, 746–748, 1976]. Previous studies have demonstrated the interaction of auditory and visual streams at the auditory cortex level, but the importance of these interactions for the qualitative perception change remained unclear because the change could result from interactions at higher processing levels as well. In our electroencephalogram experiment, we combined the McGurk effect with mismatch negativity (MMN), a response that is elicited in the auditory cortex at a latency of 100–250 msec by any above-threshold change in a sequence of repetitive sounds. An “odd-ball” sequence of acoustic stimuli consisting of frequent /va/ syllables (standards) and infrequent /ba/ syllables (deviants) was presented to 11 participants. Deviant stimuli in the unisensory acoustic stimulus sequence elicited a typical MMN, reflecting discrimination of acoustic features in the auditory cortex. When the acoustic stimuli were dubbed onto a video of a mouth constantly articulating /va/, the deviant acoustic /ba/ was heard as /va/ due to the McGurk effect and was indistinguishable from the standards. Importantly, such deviants did not elicit MMN, indicating that the auditory cortex failed to discriminate between the acoustic stimuli. Our findings show that visual stream can qualitatively change the auditory percept at the auditory cortex level, profoundly influencing the auditory cortex mechanisms underlying early sound discrimination.
The Cortical Underpinnings of Context-based Memory Distortion
Authors: Aminoff Elissa , Schacter Daniel L. , Bar Moshe 
Published: May 2008

Abstract
Everyday contextual settings create associations that later afford generating predictions about what objects to expect in our environment. The cortical network that takes advantage of such contextual information is proposed to connect the representation of associated objects such that seeing one object (bed) will activate the visual representations of other objects sharing the same context (pillow). Given this proposal, we hypothesized that the cortical activity elicited by seeing a strong contextual object would predict the occurrence of false memories whereby one erroneously “remembers” having seen a new object that is related to a previously presented object. To test this hypothesis, we used functional magnetic resonance imaging during encoding of contextually related objects, and later tested recognition memory. New objects that were contextually related to previously presented objects were more often falsely judged as “old” compared with new objects that were contextually unrelated to old objects. This phenomenon was reflected by activity in the cortical network mediating contextual processing, which provides a better understanding of how the brain represents and processes context.
Age Differences in Target Detection and Interference Resolution in Working Memory: An Event-related Potential Study
Authors: Tays William J. , Dywan Jane , Mathewson Karen J. , Segalowitz Sidney J. 
Published: May 2008

Abstract
There is growing consensus that a decline in attentional control is a core aspect of cognitive aging. We used event-related potentials to examine the time course of attentional control in older and younger adults as they attempted to resolve familiarity-based and response-based interference during a working memory task. Accuracy was high for both groups but their neural response to targets and to distracters was markedly different. Young adults' early target selection was evident by 300 msec in a differentiated P3a and they responded to interference by generating a medial frontal negativity (MFN) to distracters by 450 msec that was largest when the need for interference resolution was greatest. Dipole source analyses revealed a temporal coactivation of the inferior frontal and anterior cingulate cortex in younger adults, suggesting that these regions may interact during interference resolution. Older adults did not show the early target-selective P3a effect and failed to subsequently produce the MFN in response to distracting stimuli. In fact, older adults showed a large frontal positivity in place of the MFN but, rather than serve a compensatory role, this frontal activation was associated with poorer behavioral performance. These data suggest that aging interferes with a dynamic interplay of early target selection followed by later suppression of distracter-related neural activity—a process central to the efficient control of attention.
Is the Error-related Negativity Amplitude Related to Error Detectability? Evidence from Effects of Different Error Types
Authors: Maier Martin , Steinhauser Marco , Hübner Ronald 
Published: May 2008

Abstract
The present study tested error detection theories of the error-related negativity (ERN) by investigating the relation between ERN amplitude and error detectability. To this end, ERN amplitudes were compared with a behavioral measure of error detectability across two different error types in a four-choice flanker task. If an erroneous response was associated with the flankers, it was considered a flanker error, otherwise it was considered a nonflanker error. Two experiments revealed that, whereas detectability was better for nonflanker errors than for flanker errors, ERN amplitudes were larger for flanker errors than for nonflanker errors. Moreover, undetected errors led to strongly reduced ERN amplitudes relative to detected errors. These results suggest that, although error detection is necessary for an ERN to occur, the ERN amplitude is not related to error detectability but rather to error significance.
Inferences during Story Comprehension: Cortical Recruitment Affected by Predictability of Events and Working Memory Capacity
Authors: Virtue Sandra , Parrish Todd , Jung-Beeman Mark 
Published: May 2008

Abstract
Although it has been consistently shown that readers generate bridging inferences during story comprehension, little is currently known about the neural substrates involved when people generate inferences and how these substrates shift with factors that facilitate or impede inferences, such as whether inferences are highly predictable or unpredictable. In the current study, functional magnetic resonance imaging (fMRI) signal increased for highly predictable inferences (relative to events that were previously explicitly stated) bilaterally in both the superior temporal gyri and the inferior frontal gyri. Interestingly, high working memory capacity comprehenders, who are most likely to generate inferences during story comprehension, showed greater signal increases than did low working memory capacity comprehenders in the right superior temporal gyrus and right inferior frontal gyrus. When comprehenders needed to draw unpredictable inferences in a story, fMRI signal increased relative to explicitly stated events in the left inferior gyrus and in the middle frontal gyrus, irrespective of working memory capacity. These results suggest that the predictability of a text (i.e., the causal constraint) and the working memory capacity of the comprehender influence the different neural substrates involved during the generation of bridging inferences.
The Role of Awareness in Processing of Oculomotor Capture: Evidence from Event-related Potentials
Authors: Belopolsky Artem V. , Kramer Arthur F. , Theeuwes Jan 
Published: May 2008

Abstract
Previous research has shown that task-irrelevant onsets trigger an eye movement in their direction. Such oculomotor capture is often impervious to conscious awareness. The present study used event-related brain potentials to examine how such oculomotor errors are detected, evaluated, and compensated for and whether awareness of an error played a role at any of these stages of processing. The results show that the early processes of error detection and correction (as represented by the error-related negativity and the parietal N1) are not directly affected by subjective awareness of making an error. Instead, they seem to be modulated by the degree of temporal overlap between the programming of the correct and erroneous saccade. We found that only a later component (the error-related positivity [Pe]) is modulated by awareness of making an erroneous eye movement. We propose that awareness of oculomotor capture primarily depends on this later process.
Orographic Flow Response to Variations in Upstream Humidity
Authors: Reeves Heather Dawn , Rotunno Richard 
Published: May 2008

AbstractThe effects of upstream relative humidity (RH) on low-level wind and precipitation patterns for low-speed, statically stable flows over a mountain are investigated using idealized two- and three-dimensional numerical-simulation experiments in which RH is increased from 0% to 100%. For RH less than some critical threshold, the flow upstream becomes less decelerated as RH is increased; for RH greater than this threshold, the flow upstream becomes more decelerated as RH is increased. This increasing deceleration with RH is due to locally enhanced static stability resulting from enhanced condensation near the freezing level. Analyses from the simulations indicate that the lifted condensation level and the height of the freezing level are significant control parameters for the upstream-flow deceleration in the steady-state solutions. Dimensional analysis using these control parameters (as well as others) brings forth new nondimensional parameters that are shown to enter into analytic formulas for the orographic upstream-flow deceleration in a moist atmosphere.
Influence of Spatial Resolution on Diurnal Variability during the North American Monsoon

Published: May 2008

Abstract
Diurnal variability is an important yet poorly understood aspect of the warm-season precipitation regime over southwestern North America. In an effort to improve its understanding, diurnal variability is investigated numerically using the fifth-generation Pennsylvania State University (PSU)–NCAR Mesoscale Model (MM5). The goal herein is to determine the possible influence of spatial resolution on the diurnal cycle.
The model is initialized every 48 h using the operational NCEP Eta Model 212 grid (40 km) model analysis. Model simulations are carried out at horizontal resolutions of both 9 and 3 km. Overall, the model reproduces the basic features of the diurnal cycle of rainfall over the core monsoon region of northwestern Mexico and the southwestern United States. In particular, the model captures the diurnal amplitude and phase, with heavier rainfall at high elevations along the Sierra Madre Occidental in the early afternoon that shifts to lower elevations along the west slopes in the evening. A comparison to observations (gauge and radar data) shows that the high-resolution (3 km) model generates better rainfall distributions on time scales from monthly to hourly than the coarse-resolution (9 km) model, especially along the west slopes of the Sierra Madre Occidental. The model has difficulty with nighttime rainfall along the slopes, over the Gulf of California, and over Arizona.
A comparison of surface wind data from three NCAR Integrated Sounding System (ISS) stations and the Quick Scatterometer (QuikSCAT) to the model reveals a low bias in the strength of the Gulf of California low-level jet, even at high resolution. The model results indicate that outflow from convection over northwestern Mexico can modulate the low-level jet, though the extent to which these relationships occur in nature was not investigated.
Midlatitude Cyclone Compositing to Constrain Climate Model Behavior Using Satellite Observations

Published: May 2008

Abstract
Identical composite analysis of midlatitude cyclones over oceanic regions has been carried out on both output from the NCAR Community Atmosphere Model, version 3 (CAM3) and multisensor satellite data. By focusing on mean fields associated with a single phenomenon, the ability of the CAM3 to reproduce realistic midlatitude cyclones is critically appraised. A number of perturbations to the control model were tested against observations, including a candidate new microphysics package for the CAM. The new microphysics removes the temperature-dependent phase determination of the old scheme and introduces representations of microphysical processes to convert from one phase to another and from cloud to precipitation species. By subsampling composite cyclones based on systemwide mean strength (mean wind speed) and systemwide mean moisture the authors believe they are able to make meaningful like-with-like comparisons between observations and model output. All variations of the CAM tested overestimate the optical thickness of high-topped clouds in regions of precipitation. Over a system as a whole, the model can both over- and underestimate total high-topped cloud amounts. However, systemwide mean rainfall rates and composite structure appear to be in broad agreement with satellite estimates. When cyclone strength is taken into account, changes in moisture and rainfall rates from both satellite-derived observations and model output as a function of changes in sea surface temperature are in accordance with the Clausius–Clapeyron equation. The authors find that the proposed new microphysics package shows improvement to composite liquid water path fields and cloud amounts.
Upstream Nonoscillatory Advection Schemes
Authors: Li Jian-Guo 
Published: May 2008

Abstract
Upstream nonoscillatory (UNO) advection schemes are derived by optimizing existing classical advection schemes and combining them in different monotonic zones to avoid flux limiters for simplicity. The UNO schemes are extended to irregular grids in the form of upstream midflux linear interpolation with symmetrical gradients and are adapted to multidimensions with an advective–conservative operator. They are given in finite-volume flux form and hence are consistent and conservative. They also preserve constancy and linear correlation. Implicit numerical diffusivity of these schemes is also derived and used as a guideline for the selection of advection schemes. One- and two-dimesional tests are used for comparisons with their classical counterparts. Multiple-cell grids are used to test the irregular grid formulation and demonstrate their performance. The simple second-order UNO2 scheme may be accurate enough when the physical diffusion or numerical smoothing term is larger than the numerical diffusion. The third-order UNO3 scheme has very small self-constrained numerical diffusion and is suitable for general atmospheric and oceanic tracer advection.
Staff Voices: What Helps Students With High Mental Health Support Needs Connect to School?
Authors: Anderson Sarah , Kerr-Roubicek Helen , Rowling Louise 
Published: May 2008

AbstractResearch indicates that an important determinant of mental health is the degree to which someone feels connected to his or her environment. For young people, how they feel about ‘fitting in’ at school, in terms of peers, staff and the curriculum, is an important factor in their wellbeing. An effective whole school mental health promotion approach will therefore involve the creation of a school environment that encourages a sense of belonging and connection for its students. While the theory behind student connection to school has received a significant level of attention in the education, health and crime prevention literature, not so much is known about how school staff understand the process of ‘students connecting to school’ and what they do to enable it. Even less is reported about the experiences and views of students with high mental health support needs themselves on the issue (see Unheard Voices, Holdsworth & Blanchard, 2005). Therefore, the following study was conducted to seek understanding of the perspectives of school staff about how students connect to school and the implications for enabling the connection of students with high mental health support needs. Qualitative analysis of interviews revealed the emergence of a number of themes that align with previous research on connection to school. This study formed part of the MindMatters Plus initiative, a combined health and education best practice approach to improving the mental health outcomes of secondary school students with high support needs. The findings of this study have practical implications for school staff who are looking for ways to further enable student connection to school. They also add a complementary perspective to those of students as extrapolated in Holdsworth and Blanchard (2005).
