The SBI Program and Student Outcomes: A Study of Business Policy Classes

This study represents a preliminary inquiry ID to determine the value of combining SBI and Policy into a singular curriculum. A comparison of this combined formal was made wi1h the traditional Policy course. A slightly modified Job Diagnostic Survey (Hackman & Oldham, 1975) and a skills/usefulness scale (Hoffman, Fon1eno1 & Viswanathan, 1990) was administered to assess the difference between the two groups. Results suggested that the combined format met or exceeded the ou1comes of the traditional Policy course

SBI Intervention: An Old Problem- A New Perspective

This research effort attempted to determine if SB/ intervention would change the perception of business problems by not only the business owner but also the student consultants. This focus further to encompassed firms that could be classified in either Stage I or Stage II of development. Even though there were no changes in perception by student consultants, and mixed results of whether stage development affected perceptual differences, strong support was given to the proposition that owners, overall, did change their perception of existing problems after SBI intervention

State of Inequity: Three Essays on Disparities in Justice Provision

Inequities in public service provision refer to disparate outputs and outcomes among social groups. This dissertation addresses inequalities in justice provision in American society and has three objectives. The first objective is to test whether the race and ethnicity of top elected law-enforcement officials mitigate disparities in juvenile justice provision among social groups. The second objective is to examine whether the gender of top elected law-enforcement officials affects the severity of justice outcomes at the street level. The third objective is to analyze institutional responses on social media platforms to police misconduct and social unrest after the death of George Floyd. Each objective is addressed in a separate essay. The first essay examines racial and ethnic inequities in the juvenile justice system by comparing the outcomes among minority youth. The study hypothesizes that the sheriff and state attorney’s party affiliation and race/ethnicity mitigate the inequalities in justice provision among social groups. Data from all 67 Florida counties between 2015 and 2020 demonstrate that the effect goes more through race than ideology. In this sense, representative bureaucracy theory appears more relevant than political control in explaining the distribution of justice outcomes. The second essay inquiries if arrests and prosecutions among youth vary as a function of sheriffs’ and state attorneys’ sex. Drawing on data from Florida counties between 2015 and 2020, the analysis shows that counties with female sheriffs and state attorneys experience fewer youth arrests and prosecutions than those led by men, especially among minority and female offenders. The finding that women’s leadership is positively associated with less severe outcomes for delinquent young lends more support to emotional labor than theories of gendered organizational socialization and representative bureaucracy. The third essay analyzes the content and timing of initial statements by mayors and police chiefs on nationwide demonstrations against unequal treatment of minorities. Responsiveness is conceptualized through the lenses of political control and representative bureaucracy theories. The study’s findings reveal that mayors’ responsiveness goes along the party lines but not for police chiefs. The statements of Black police chiefs support the expectations of representative bureaucracy theory but only in terms of content and not in timing. The broader social value of this dissertation lies in documenting the presence of vast inequalities in justice provision among social groups, often with life-lasting consequences for young offenders, and proposing possible mechanisms to remedy them

Picornavirus Subversion of the Autophagy Pathway

While autophagy has been shown to act as an anti-viral defense, the Picornaviridae avoid and, in many cases, subvert this pathway to promote their own replication. Evidence indicates that some picornaviruses hijack autophagy in order to induce autophagosome-like membrane structures for genomic RNA replication. Expression of picornavirus proteins can specifically induce the machinery of autophagy, although the mechanisms by which the viruses employ autophagy appear to differ. Many picornaviruses up-regulate autophagy in order to promote viral replication while some members of the family also inhibit degradation by autolysosomes. Here we explore the unusual relationship of this medically important family of viruses with a degradative mechanism of innate immunity

Reinforcer magnitude and demand under fixed-ratio schedules with domestic hens

This study compared three methods of normalizing demand functions to allow comparison of demand for different commodities and examined how varying reinforcer magnitudes affected these analyses. Hens responded under fixed-ratio schedules in 40-min sessions with response requirement doubling each session and with 2-s, 8-s, and 12-s access to wheat. Over the smaller fixed ratios overall response rates generally increased and were higher the shorter the magazine duration. The logarithms of the number of reinforcers obtained (consumption) and the fixed ratio (price) were well fitted by curvilinear demand functions (Hursh et al., 1988. Journal of the Experimental Analysis of Behavior 50, 419–440) that were inelastic (b negative) over small fixed-ratios. The fixed ratio with maximal response rate (Pmax) increased, and the rate of change of elasticity (a) and initial consumption (L) decreased with increased magazine duration. Normalizing consumption using measures of preference for various magazine durations (3-s vs. 3-s, 2-s vs. 8-s, and 2-s vs. 12-s), obtained using concurrent schedules, gave useful results as it removed the differences in L. Normalizing consumption and price (Hursh and Winger, 1995. Journal of the Experimental Analysis of Behavior 64, 373–384) unified the data functions as intended by that analysis. The exponential function (Hursh and Silberberg, 2008. Psychological Review, 115, 186–198) gave an essential value that increased (i.e., α decreased significantly) as magazine duration decreased. This was not as predicted, since α should be constant over variations in magazine duration, but is similar to previous findings using a similar procedure with different food qualities (hens) and food quantities (rats)

Lasing from a circular Bragg nanocavity with an ultra-small modal volume

We demonstrate single-mode lasing at telecommunication wavelengths from a circular nanocavity employing a radial Bragg reflector. Ultra-small modal volume and Sub milliwatt pump threshold level are observed for lasers with InGaAsP quantum well active membrane. The electromagnetic field is shown to be tightly confined within the 300nm central pillar of the cavity. The quality factors of the resonator modal fields are estimated to be on the order of a few thousands.Comment: 3 pages, 4 figures Submitted to AP
