...Scaling Study RES/320 Dr. Jeffrey Putnam Scaling Study Developing and conducting a survey is a very technical process. Any researcher that takes on a process like this must be careful to develop proper and appropriate questions for the survey to collect the most valid and reliable data. Conducting and presenting the survey is just as crucial as the creation of the questions. If either of these areas is neglected or not handled appropriately the entire research process is wasted. The purpose this paper is to critique a survey I created and issued to 10 random individuals. Included in the critique of this survey is a discussion of the reliability and validity of the survey and the results collected. Survey and Content The survey under review is a short eight questions developed to understand general health of individuals through diet and exercise. The survey was completed using two forms of questions. The first type question falls under the definition of a rating scale. “Rating scale is used when participants score an object or indicant without making a direct comparison to another object or attitude” (Cooper, Schindler, 2011, Ch. 12). Under these guidelines individuals were asked to answer questions pertaining to how often they exercise, how often they eat each day, and how often they eat fast food. These questions are created so there can be no comparisons made, but rather a numerical value selection. The second sets of questions are a version of ranking scale inquiries...

...IEEE JOURNAL OF SOLID-STATE CIRCUITS, VOL. 47, NO. 7, JULY 2012 1585 A 53-nW 9.1-ENOB 1-kS/s SAR ADC in 0.13- m CMOS for Medical Implant Devices Dai Zhang, Student Member, IEEE, Ameya Bhide, Student Member, IEEE, and Atila Alvandpour, Senior Member, IEEE Abstract—This paper describes an ultra-low power SAR ADC for medical implant devices. To achieve the nano-watt range power consumption, an ultra-low power design strategy has been utilized, imposing maximum simplicity on the ADC architecture, low transistor count and matched capacitive DAC with a switching scheme which results in full-range sampling without switch bootstrapping and extra reset voltage. Furthermore, a dual-supply voltage scheme allows the SAR logic to operate at 0.4 V, reducing the overall power consumption of the ADC by 15% without any loss in performance. The ADC was fabricated in 0.13- m CMOS. In dual-supply mode (1.0 V for analog and 0.4 V for digital), the ADC consumes 53 nW at a sampling rate of 1 kS/s and achieves the ENOB of 9.1 bits. The leakage power constitutes 25% of the 53-nW total power. Index Terms—ADC, analog-to-digital conversion, leakage power consumption, low-power electronics, medical implant devices, successive approximation. I. INTRODUCTION EDICAL implant devices, such as pacemakers and implantable cardiac defibrillators, target increasingly advanced signal acquisition and signal processing systems. Such devices, which are to be implanted in the human body, require extremely low...

...Power-Aware Linear Programming Based Scheduling For Heterogeneous Computer Clusters This paper presents power aware scheduling policy for Heterogeneous Clusters. In general, in performance optimization of computer clusters, energy consumption has been mostly neglected, which is an important factor. Reduction of energy consumption in computer cluster is a necessity because cooling equipment is not a good idea as electricity costs are growing at a faster rate. This policy provides significant energy savings. In this paper, it is also suggested that a power-aware policy for structured systems only requires knowledge of the ranking of machines with respect to their power efficiencies and structured systems are a special kind of heterogeneous systems that are common for cluster environments. II. WORKLOAD MODEL In this model a dedicated front end scheduler is used to assign incoming tasks to back end machine. If the number of machines be J and tasks are classified into i classes. Let α be the arrival matrix rate and the ith element of α isαi. Assuming tasks of class i reaches front end at αi. In this model, the expected task execution time is estimated by classifying the groups or classes with identical distribution. The policy considered here is an estimate on mean execution time rather than exact execution time. Let μi,jbe the execution rate for tasks of class i at machine j, hence 1/μi,jis the mean execution time for class i tasks at machine j. III. CURRENT POLICIES The...

...Book Review 1 – ‘Children’s Solution Work’ by Insoo Kim Berg & Therese Steiner I chose to do my first book review of the year on ‘Children’s solution work’, as I was intrigued as to how this modality can be applied to children. My practice to date involves only adults so I am very keen to adopt tools and tips to effectively talk to children in a therapeutic way. I was definitely not disappointed! This book clearly demonstrated how the Solution-Focused Brief Therapy (SFBT) model can be applied to the nonverbal, playful and creative habits of children. The books extensive use of examples and case studies in various contexts and situations was instrumental in demonstrating the creative techniques and strategies for working with children without relying exclusively on language. I will use this book review to discuss some of the ideas, techniques and cases that really stood out for me with the hope that I may one day incorporate them into my clinical work. “There is good harmony between SFBT and children because there are so many similarities between how children think and make sense of the world around them and the assumptions and procedures of SFBT.” One excellent example of this is the child’s relative indifference to the “cause” of a problem, over their need/desire to “fix” it. I encounter this on a daily basis with my own children. I often find myself inquiring about the cause of their problems, feeling that by doing so I will gain greater insight into their thoughts...

...Nucleon Case Study The date is December 1990 and Nucleon, a biotech startup specializing in R&D, is having a difficult time deciding which route to take to get FDA approval for their product (CRP-1), while still creating the most value for their company and obtaining funding for future innovations. Nucleon is one of 200+ biotech companies in a relatively new field, racing to gain a proprietary position through R&D efforts, but lack the capital and manufacturing capabilities to bring their product through clinical trials and to the market. Thus several options are available for Phase I & 2 of clinical trials, as well as Phase III and can be seen in Figure 1 below. At first glance of the Nucleon decision tree (Figure 1), it would appear that based on the values under the net present value (NPV) column that option C would result in the most financial gain and future success. Option C would involve Nucleon passing Phase I & II of clinical trials through contract manufacturing methods and then by scaling up in Phase III to produce the amount of product needed to pass FDA requirements and meet market demand. However, choosing innovation strategies is based not only on quantitative results like that of the NPV, but also qualitative results in order to weigh factors that are not so easy to quantify. When quantitative and qualitative factors are then analyzed, one can see that option E is in fact the most beneficial to Nucleon’s success. Option E involves Nucleon licensing...

...Abstract The quest for an answer to what determines human behavior has been going on for many years now, is it nature or nurture? The broad scope of human behavior has compelled researchers across various fields to systematically analyze what compels individuals to act the way they do. Is human behavior encoded in genetics or does it evolve by way of individual experience and environment. Through the review of recent empirical data across these various fields it is clear that both nature and nurture plan an important role in the development of human behavior. Subsequently multidirectional models have emerged with a mounting emphasis on how nature and nurture act independently in addition to collectively each forever shaping the other. Together Nature and Nurture Shape Human Behavior. The discussion concerning the appropriate significance of genetics and environment in human behavior has been around for quite a long while. This topic has generated massive attention, throughout the years, gaining numerous supporters on both sides of the debate. This attention essentially, has lead to some of the most remarkable psychological discoveries in recent years. The terms nature and nurture can be traced back to13th century France, expressed by Francis Galton in 1874 (Nature versus nurture, 2011). The term nurture in refers to the manner in which behavior is shaped by culture and environment. It builds its foundation on John B. Watson's theory of behaviorism...

This paper investigates the nature of deviant workplace behaviors and its impact on organizations. The purpose is to broaden the research in organizational studies by focusing not only on deviant behaviors that are negative, but on those that are positive as well. Furthermore, this article examines different types of both positive and negative deviant workplace behaviors, along with some of the reasons why managers/employees engage in such behaviors. Also, some of the reasons why organizations allow negative deviant behaviors to thrive, while discouraging positive deviant behaviors are investigated. Lastly, possible solutions to overcome problems arising from negative deviance in the workplace will be examined, along with how organizations can encourage positive deviant behaviors. ORGANISATIONAL BEHAVIOR Organizational Behavior (OB) a field of study that investigates the impact that individuals, groups, and structure have on behavior within organizations, for the purpose of applying such knowledge toward improving an organization’s effectiveness.

...Chapter 1 Case Study: Harmonix Embrace Your Inner Rock Star Little more than three years ago, you had probably never heard of Harmonix. In 2005, the video game design studio released Guitar Hero, which subsequently became the fastest video game in history to top $1 billion in North American sales. The game concept focuses around a plastic guitar-shaped controller. Players press colored buttons along the guitar neck to match a series of dots that scroll down the TV in time with music from a famous rock tune, such as the Ramones’ “I Wanna Be Sedated” and Deep Purple’s “Smoke on the Water.” Players score points based on their accuracy. In November 2007, Harmonix released Rock Band, adding drums, vocals, and bass guitar options to the game. Rock Band has sold over 3.5 million units with a $169 price tag (most video games retail at $50 to $60). In 2006, Harmonix’s founders sold the company to Viacom for $175 million, maintaining their operational autonomy while providing them greater budgets for product development and licensing music for their games. Harmonix’s success, however, did not come overnight. The company was originally founded by Alex Rigopulos and Eran Egozy in 1995, focused around some demo software they had created in grad school and a company vision of providing a way for people without much musical training or talent to experience the joy of playing and creating music. The founders believed that if people had the opportunity to create their own music, they would jump...
