Rethinking Spectrum Governance After the FAA and FCC’s Turf War Over 5G
The rollout of 5G technology promised transformative benefits for consumers and the economy. But a protracted dispute between the FCC and FAA relating to 5G interference with airplane safety equipment prevented a smooth 5G rollout. While the FCC was giving wireless companies the green light to roll out 5G service, the FAA was warning of apocalypse if they did. What resulted was a turf war between the FAA and FCC, revealing a dysfunctional process (or lack thereof) for handling spectrum interference concerns. This Comment argues that the United States’ spectrum management system needs an overhaul to prevent similar agency turf wars over spectrum policy. This overhaul can be achieved partly by consolidating some spectrum management authority, currently dispersed between multiple agencies, in a single agency. And it can be achieved by enhancing coordination and cooperation between agencies where authority over spectrum policy remains dispersed
Automated tracking of the Florida manatee (Trichechus manatus)
The electronic, physical, biological and environmental factors involved in the automated remote tracking of the Florida manatee (Trichechus manatus) are identified. The current status of the manatee as an endangered species is provided. Brief descriptions of existing tracking and position locating systems are presented to identify the state of the art in these fields. An analysis of energy media is conducted to identify those with the highest probability of success for this application. Logistic questions such as the means of attachment and position of any equipment to be placed on the manatee are also investigated. Power sources and manateeborne electronics encapsulation techniques are studied and the results of a compter generated DF network analysis are summarized
Using the Counseling Center Assessment of Psychological Symptoms-70 (CCAPS-70) and the Personality Assessment Inventory (PAI) to Predict Treatment Duration and Premature Termination
Severity of client psychological distress, along with scarcity of clinical resources such as effective screening tools, continues to increase in university counseling centers. Pearson’s correlation, logistic regression, and standard multiple regression analyses compared the concurrent and predictive validity of two measures of global psychological functioning, the Counseling Center Assessment Psychological Functioning-70 (CCAPS-70) and the Personality Assessment Inventory (PAI). Results demonstrated support for both instruments’ ability to identify symptoms placing clients at risk for premature counseling termination and subsequent prolonged impairment. Implications for clinical practice and further research pertaining to university counseling center services are discussed
Echoes of Vision: Mental Imagery in the Human Brain
When you picture the face of a friend or imagine your dream house, you are using the same parts of your brain that you use to see. How does the same system manage to both accurately analyze the world around it and synthesize visual experiences without any external input at all? We approach this question and others by extending the well-established theory that the human visual system embodies a probabilistic generative model of the visual world. That is, just as visual features co-occur with one another in the real world with a certain probability (the feature “tree” has a high probability of occurring with the feature “green”), so do the patterns of activity that encode those features in the brain. With such a joint probability distribution at its disposal, the brain can not only infer the cause of a given activity pattern on the retina (vision), but can also generate the probable visual consequence of an assumed or remembered cause (imagery). The formulation of this model predicts that the encoding of imagined stimuli in low-level visual areas resemble the encoding of seen stimuli in higher areas. To test this prediction we developed imagery encoding models-a novel tool that reveals how the features of imagined stimuli are encoded in brain activity. We estimated imagery encoding models from brain activity measured while subjects imagined complex visual stimuli, and then compared these to visual encoding models estimated from a matched viewing experiment. Consistent with our proposal, imagery encoding models revealed changes in spatial frequency tuning and receptive field properties that made early visual areas during imagery more functionally similar to higher visual areas during vision. Likewise, signal and noise properties of the voxel activation between vision and imagery favor the generative model interpretation. Our results provide new evidence for an internal generative model of the visual world, while demonstrating that vision is just one of many possible forms of inference that this putative internal model may support
Evaluation of an Unfractioned Heparin Pharmacy Dosing Protocol for the Treatment of Venous Thromboembolism in Nonobese, Obese, and Severely Obese Patients
Background: Despite large interpatient variability in dose response, heparin is utilized for treatment of venous thromboembolism (VTE). Current data on the optimal heparin dosing in obese patients are conflicting. Objective: The objective was to evaluate the time and dose required to achieve a therapeutic activated partial thromboplastin time (aPTT) in nonobese, obese, and severely obese patients using a pharmacist-directed heparin dosing protocol. Methods: This was a retrospective cohort study in a single-center community hospital inpatient setting. Adult patients receiving heparin for VTE treatment from July 1, 2013, to July 31, 2015, were evaluated. Patients were categorized into 3 groups: nonobese (BMI \u3c 30 kg/m2), obese (BMI = 30-39.9 kg/m2), and severely obese (BMI ≥ 40 kg/m2). Data on height, weight, initial bolus dose, initial infusion rate, time to therapeutic aPTT, and therapeutic infusion rate were collected. Dosing body weight (DBW) was utilized for patients 20% over their ideal body weight (IBW). The primary outcome was time to therapeutic aPTT. Results: Analysis included 298 patients. Median times to therapeutic aPTT (hours:minutes) in the nonobese, obese, and severely obese were 15:00 (interquartile range [IQR] = 8:05-23:21), 15:40 (IQR = 9:22-25:10), and 15:22 (IQR = 7.54-23:40), respectively (P = 0.506). There was no difference in bleeding among the nonobese (14%), obese (13.9%), or severely obese groups (7.9%; P = 0.453). No adverse thrombotic events occurred during hospitalization. Conclusion: Using a DBW for heparin dosing in patients 20% over their IBW resulted in similar times to therapeutic aPTT and adverse events in the nonobese, obese, and severely obese
The Essential Nature of Humility for Today\u27s Leaders
Using socio-rhetorical criticism and analysis, the author explores the inner-textual and intertextual texture of 1 timothy 3:1-7. In particular the author draws out how the apostle Paul’s leadership requirement of not being a recent convert is less about the timing of a conversion to christianity and more about the adverse effects of pride on the ability of a leader to lead in a healthy manner. In so doing, the author provides support and insight into the ways in which humility as an essential virtue is applicable to leadership in secular settings as well as christian environments. Furthermore, the author strengthens the case by citing multiple points in secular leadership literature where humility is seen as a positive virtue as opposed to a vice. this is done in order to establish a basis for the encouragement of christian leadership theorists and practitioners to continue their efforts to influence secular theories of leadership and the subsequent applications toward a christian outlook
