The Effects of Bogus Amounts of Perceived Success on Achieving a Desired Physiological State

Thirty incarcerated juveniles underwent thermometric bio-feedback training. The subjects were divided into three groups; (1) Inflated, in which information was doubled, (2) Actual, in which no alterations were made, and (3) Deflated, in which information was half of the true temperature rise. No significant difference was found among these groups. A self-report rating on various attitudes, primarily success feelings ; were correlated with achievement. The only factor statistically significant was an indication of locus of control. Cognitive potentialities are discussed as well as emotion

The Effect of Increased VEGF Levels on Limb Bud Angiogenesis in a Developing Chick Embryo

Vascular endothelial growth factor (VEGF) is a necessary regulator of normal angiogenesis as it serves as a potent mitogen for vascular endothelial cells derived from arteries and veins.1 In this study, the effect of augmented levels of VEGF on limb bud angiogenesis in a developing chick embryo will be demonstrated. Alkaline phosphatase staining was used to show the presence of endothelial tissue originating from angiogenesis. We report that increased levels of VEGF resulted in an increase in dark blue alkaline phosphatase staining, suggesting that there is more enzymatic activity where endothelial cells are present. These findings support the documented role of VEGF in promoting angiogenesis

Motivating Factors of Aphid Behavior

Citation: Kruse, A. (2017). Motivating Factors of Aphid Behavior . 1st Annual Undergraduate Research Experience in Entomology Symposium, November 16, 2016. Manhattam, KS.Aphids are small, soft-bodied insects with long slender mouthparts used to pierce leaves and extract fluids; to check for aphid infestation, one must check the underside of the leaf as this is the preferential side for many aphid species [1]. Sugarcane Aphids, Melanaphis sacchari, cause serious damage to sorghum growth, development and productivity in many countries [2]. We hoped to find with this experiment what factors can best explain why Sugarcane Aphids colonize on the underside of sorghum. We found that the only two treatments that were statistically significant (mesh top/cardboard bottom, and mesh top/mesh bottom flipped) meaning that with further research we may be able to prove light is the most motivating factor of aphid colonization behavior

The effect of ratio and interval training on Pavlovian-instrumental transfer in mice.

Conditional stimuli (CS) that are paired with reward can be used to motivate instrumental responses. This process is called Pavlovian-instrumental transfer (PIT). A recent study in rats suggested that habitual responses are particularly sensitive to the motivational effects of reward cues. The current experiments examined this idea using ratio and interval training in mice. Two groups of animals were trained to lever press for food pellets that were delivered on random ratio or random interval schedules. Devaluation tests revealed that interval training led to habitual responding while ratio training produced goal-directed actions. The presentation of CSs paired with reward led to positive transfer in both groups, however, the size of this effect was much larger in mice that were trained on interval schedules. This result suggests that habitual responses are more sensitive to the motivational influence of reward cues than goal-directed actions. The implications for neurobiological models of motivation and drug seeking behaviors are discussed

Coping in the Aftermath of COVID 19 Pandemic: How to Navigate Mental and Emotional Challenges

This workshop will discuss strategies to help recognize and manage the mental, emotional, and physical health challenges of students, staff, and faculty may also encounter after the pandemic. It will delineate symptoms and suggest resources and coping strategies It will discuss health and wellness and their importance in self-care. Audience participation is encouraged

label-based security enforcement for web applications

This paper presents SELinks, a programming language focused on building secure multi-tier web applications. SE-Links provides a uniform programming model, in the style of LINQ and Ruby on Rails, with language syntax for accessing objects residing either in the database or at the server. Object-level security policies are expressed as fullycustomizable, first-class labels which may themselves be subject to security policies. Access to labeled data is mediated via trusted, user-provided policy enforcement functions. SELinks has two novel features that ensure security policies are enforced correctly and efficiently. First, SELinks implements a type system called Fable that allows a protected object’s type to refer to its protecting label. The type system can check that labeled data is never accessed directly by the program without first consulting the appropriate policy enforcement function. Second, SELinks compiles policy enforcement code to database-resident user-defined functions that can be called directly during query processing. Database-side checking avoids transferring data to the server needlessly, while still allowing policies to be expressed in a customizable and portable manner. Our experience with two sizable web applications, a model health-care database and a secure wiki with fine-grained security policies, indicates that cross-tier policy enforcement in SELinks is flexible, relatively easy to use, and, when compared to a single-tier approach, improves throughput by nearly an order of magnitude.
