    Determining the Future for Louisiana Sugar Cane Products, Inc.: A Case Study Analyzing Vertical Coordination Options

    Get PDF
    Deciding how to coordinate activities can be a challenge posed in any marketing chain. This case involves an agricultural cooperative that has focused entirely on marketing raw sugar cane for additional refinement. Recent dramatic shifts in the sector have caused the members of the cooperative to consider building a facility that will process the raw sugar cane. In so doing, the cooperative can consider using the spot market, using contracts, vertically coordinating, or vertically integrating. This case study of Louisiana Sugar Cane Products, Inc. is a unique, real-life case that can be widely used in marketing and cooperatives courses.Agribusiness, Crop Production/Industries,

    Feature-Based Change Detection Reveals Inconsistent Individual Differences in Visual Working Memory Capacity

    Visual working memory (VWM) is a key cognitive system that enables people to hold visual information in mind after a stimulus has been removed and compare past and present to detect changes that have occurred. VWM is severely capacity limited to around 3–4 items, although there are robust individual differences in this limit. Importantly, these individual differences are evident in neural measures of VWM capacity. Here, we capitalized on recent work showing that capacity is lower for more complex stimulus dimension. In particular, we asked whether individual differences in capacity remain consistent if capacity is shifted by a more demanding task, and, further, whether the correspondence between behavioral and neural measures holds across a shift in VWM capacity. Participants completed a change detection (CD) task with simple colors and complex shapes in an fMRI experiment. As expected, capacity was significantly lower for the shape dimension. Moreover, there were robust individual differences in behavioral estimates of VWM capacity across dimensions. Similarly, participants with a stronger BOLD response for color also showed a strong neural response for shape within the lateral occipital cortex, intraparietal sulcus (IPS), and superior IPS. Although there were robust individual differences in the behavioral and neural measures, we found little evidence of systematic brain-behavior correlations across feature dimensions. This suggests that behavioral and neural measures of capacity provide different views onto the processes that underlie VWM and CD. Recent theoretical approaches that attempt to bridge between behavioral and neural measures are well positioned to address these findings in future work

    The Effects of tDCS Across the Spatial Frequencies and Orientations that Comprise the Contrast Sensitivity Function

    Richard B, Johnson AP, Thompson B and Hansen BC (2015) The Effects of tDCS Across the Spatial Frequencies and Orientations that Comprise the Contrast Sensitivity Function. Front. Psychol. 6:1784. doi: 10.3389/fpsyg.2015.01784Transcranial Direct Current Stimulation (tDCS) has recently been employed in traditional psychophysical paradigms in an effort to measure direct manipulations on spatial frequency channel operations in the early visual system. However, the effects of tDCS on contrast sensitivity have only been measured at a single spatial frequency and orientation. Since contrast sensitivity is known to depend on spatial frequency and orientation, we ask how the effects of anodal and cathodal tDCS may vary according to these dimensions. We measured contrast sensitivity with sinusoidal gratings at four different spatial frequencies (0.5, 4, 8, and 12 cycles/°), two orientations (45° Oblique and Horizontal), and for two stimulus size conditions [fixed size (3°) and fixed period (1.5 cycles)]. Only contrast sensitivity measured with a 45° oblique grating with a spatial frequency of 8 cycles/° (period = 1.5 cycles) demonstrated clear polarity specific effects of tDCS, whereby cathodal tDCS increased and anodal tDCS decreased contrast sensitivity. Overall, effects of tDCS were largest for oblique stimuli presented at high spatial frequencies (i.e., 8 and 12 cycles/°), and were small or absent at lower spatial frequencies, other orientations and stimulus size. Thus, the impact of tDCS on contrast sensitivity, and therefore on spatial frequency channel operations, is opposite in direction to other behavioral effects of tDCS, and only measurable in stimuli that generally elicit lower contrast sensitivity (e.g., oblique gratings with period of 1.5 cycles at spatial frequencies above the peak of the contrast sensitivity function).Portions of the current study were funded by a discovery grant from the Natural Sciences and Engineering Research Council (NSERC) to AJ, and by the Colgate Research Council Grant to BH. BR was supported by the Fonds de Recherche du Quebec – Nature et Technologie (FQRNT), and a bursary from the Ministère de l’Éducation, de l’Enseignement supérieur et de la Recherche (MEESR)

    Reduction in Drinking Days and Binge Drinking Days among Patients Receiving Screening, Brief Intervention, and Referral to Treatment Services during an Emergency Department Visit: Six-month Results

    Get PDF
    Alcohol screening and brief intervention (SBI) is effective in many health-care settings. Previous research has shown significant decreases in harmful drinking due to SBI, but many studies, particularly in emergency/trauma settings, did not use a control group. Thus, it is unclear if observed decreases in harmful drinking are due to the intervention or other factors such as the hospital visit, the substance use assessment, or simply regression to the mean. This project assessed the effectiveness of an SBI program implemented at an urban hospital in the US state of Georgia

    Boys and their toys : status inconsistency in non-democratic regimes and the import of major weapon systems

    Get PDF
    Major weapon system imports are significant as they are useful for domestic and international security. However, states regularly imported weapons they want in addition to weapons they need. One explanation is that states import unnecessary weapons to gain status. We argue that states suffering from higher levels of negative status inconsistency (SI) import a greater proportion of status symbol weapons. To account for differing security motives, we also separate non-democratic regime types – strongman, junta, boss, and machine – as they vary in their international conflict propensity and domestic stability. Due to the differences across these regimes, we further argue that non-democratic personalist regimes will import more status symbol weapons. Using data covering 1965–1999, we find that negatively status inconsistent regimes import more status symbol weapons
