Attitudes Toward Green Computing In The Us: Can They Change?

Computers today are an essential part of individuals’ lives all around the world; however, these tools are extremely toxic to the environment given the materials used, limited battery life and technological obsolescence. The US and the EU’s policies regarding this and other e-waste differ with greater support for the Basel Convention among Europeans. Although computer manufacturers are working to build “green” computers, a large part of limiting such hazardous wastes rests with consumers when purchasing them. Hence, the purpose of the study was to determine if information presented to consumers would influence their attitudes regarding green computing and purchases. A self-administered questionnaire was developed to determine consumers’ attitudes toward the environment, attitudes toward green computing, and demographic characteristics. It was hypothesized that there would be no differences in consumers’ attitudes before or after reading the information on computer toxicity. A convenience sample of students enrolled in marketing courses at a southwestern university, were surveyed. Results of Paired T-tests revealed significant differences for 13 of the 15 statements at the p
The effect of taekwondo training on strength and balance of young adults with Down syndrome

According to the National Down Syndrome Society (NDSS, 2012) 1 in every 691 babies born in the United States is born with Down syndrome (DS). In addition, life expectancy for people with DS has increased dramatically. With advances in medical care the number of individuals with DS living into older adulthood will continue to increase, with typical consequences of aging such as decreased strength and balance becoming more pronounced in this population. Individuals with Down syndrome (DS) are born with lower levels of strength than typically developing (TD) infants as well as having delayed development of balance. The lower levels of strength and balance continues throughout their entire lifespan. This study provided taekwondo training 2 times per week for 10 weeks to 22 young adults with DS as a different method of improving strength and balance. A control group of 22 young adults with DS was used for comparison. Lower body strength was measured utilizing hand held dynamometry (HHD), static balance was measured using the modified Clinical Test for Sensory Integration and Balance (mCTSIB) in the eyes open and eyes closed conditions and dynamic balance was measured utilizing limits of stability (LOS). Lower body strength was significantly improved in the taekwondo group at each assessment over time while the control groups’ strength levels remained unchanged. The taekwondo training group did not significantly improve static balance in either eyes open or eyes closed condition or improve dynamic balance ability. The lack of improvement may be due to lack of proper assessment orientation in some of the participants or the intervention was not of significant length to elicit physiological changes. No injuries or adverse incidents occurred due to training which may indicate taekwondo is an activity that is feasible and fun for this population.

Spacecraft Dielectric Material Properties and Spacecraft Charging

The physics of spacecraft charging is reviewed, and criteria for selecting and testing semiinsulating polymers (SIPs) to avoid charging are discussed and illustrated. Chapters are devoted to the required properties of dielectric materials, the charging process, discharge-pulse phenomena, design for minimum pulse size, design to prevent pulses, conduction in polymers, evaluation of SIPs that might prevent spacecraft charging, and the general response of dielectrics to space radiation. SIPs characterized include polyimides, fluorocarbons, thermoplastic polyesters, poly(alkanes), vinyl polymers and acrylates, polymers containing phthalocyanine, polyacene quinones, coordination polymers containing metal ions, conjugated-backbone polymers, and 'metallic' conducting polymers. Tables summarizing the results of SIP radiation tests (such as those performed for the NASA Galileo Project) are included.
The colour and composition of early Anglo-Saxon copper alloy jewellery

Copper alloy artefacts are amongst the most prolific material remains from the early Anglo-Saxon period (450-650 CE). This research attempts to circumvent the limitations of previous disparate and unconnected typological and metallurgical approaches to these objects by investigating copper alloy jewellery from a holistic interdisciplinary approach. In particular, colour is used as a major new variable, a characteristic that would have been relevant to the Anglo-Saxons as craftsmen and as consumers. This method can reveal the choices that faced Anglo-Saxon craftsmen in the manufacture of these objects and in the use of their materials according to variables relevant and appropriate to their world. All past quantitative composition data relating to this period are reanalysed collectively, to interpret and model metal supply dynamics and recycling traditions. A visual context for copper alloys is created using linguistic frequency analysis of Old English colour words alongside a discussion of other Anglo-Saxon coloured material culture. The application of quantitative colour measurement to archaeological material and the factors affecting colour in various copper alloys on a structural level is also delineated, including quantification of the limits of human colour distinction and perception, the effects of tarnish on colour, and the overlap between copper and precious metal colour space. A new dataset comprising semi-quantitative ED-XRF composition data and quantitative colour measurements from over two-hundred archaeological samples allows the context of colour and composition to be discussed, providing insight into issues of value, aesthetics, trade and metal supply, and control.
Buried-object detection using time-reversed acoustics

Abstract : In the spring of 2000, a proposal was submitted to Mr. Ken Dial at the Office of Naval Research (ONR) to study a novel approach of time-reversed acoustics to detect targets buried in a littoral environment. The proposal was written by Dr. Thomas Drake, currently at ONR, and David Pierson, currently at John Hopkins University Applied Physics Laboratory (APL), under the advice of Dr. Tony Clark, currently at North Carolina State University (NCSU), and completed under the guidance of Dr. David Aspnes, also currently at NCSU. The research demonstrated through theoretical calculations and computer simulations that time-reversed acoustics can be used to detect and classify a target buried in a inhomogeneous environment using an acoustic transceiver of simple geometry.
Productivity Convergence: Theory and Evidence

A vast new literature on the sources of economic growth has now accumulated. This book critically reviews the most significant works in this field and summarizes what is known today about the sources of economic growth. The first part discusses the most important theoretical models that have been used in modern growth theory as well as methodological issues in productivity measurement. The second part examines the long-term record on productivity among Organization for Economic Co-operation and Development (OECD) countries, considers the sources of growth among them with particular attention to the role of education, investigates convergence at the industry level among them, and examines the productivity slowdown of the 1970s. The third part looks at the sources of growth among non-OECD countries. Each chapter emphasizes the factors that appear to be most important in explaining growth performance.
Singing in Space(s): Singing performance in real and virtual acoustic environments - Singers' evaluation, performance analysis and listeners' perception

The Virtual Singing Studio (VSS), a loudspeaker-based room acoustic simulation, was developed in order to facilitate investigations into the correlations and interactions between room acoustic characteristics and vocal performance parameters. To this end, the VSS provides a virtual performance space with interactivity in real-time for an active sound source - meaning that singers can hear themselves sing as if in a real performance space. An objective evaluation of the simulation was carried out through measurement and comparison of room acoustic parameters of the simulation and the real performance space. Furthermore a subjective evaluation involved a number of professional singers who sang in the virtual and real performance spaces and reported their impressions of the experience. Singing performances recorded in the real and virtual spaces were compared via the analysis of tempo, vibrato rate, vibrato extent and measures of intonation accuracy and precision. A stimuli sorting task evaluated listeners' perception of the similarity between singing performances recorded in the real and simulated spaces. A multi-dimensional scaling analysis was undertaken on the data obtained and dimensions of the common perceptual space were identified using property fitting techniques in order to assess the relationship between performance attributes and the perceived similarities. In general significant proportions of the perceived similarity between recordings could be explained by differences in global tempo, vibrato extent and intonation precision. Although there were few statistically significant effects of room acoustic condition all singers self-reported changes to their singing according to the different room acoustic configurations, and listeners perceived these differences, especially in vibrato extent and global tempo. The present VSS has been shown to be not fully ``realistic'' enough to elicit variations in singing performance according to room acoustic conditions. Therefore, further improvements are suggested including the incorporation of visual aspect to the simulation. Nonetheless, the VSS is already able to provide a ``plausible'' interactive room acoustic simulation for singers to hear themselves in real-time as if in a real performance venue.

Dynamics of a technological innovator network and its impact on technological performance

Abstract This paper examines the dynamics of a technological innovator network (TIN) of a state-owned textile company in underdeveloped southwest China. It addresses two research questions: how the structure of the TIN evolved in the past 10 years; and what impact it had on the technological performance of the firm. The case study reveals that the general structure of the TIN and the positioning of the actors influence not only the amount of technological innovations but also the predominant type (product versus process innovations). TINs that are adequate for process innovation may not be as efficient for product innovation.
The Influence of Dynamic Lighting Conditions on Visibility: A Pilot Study

A pilot laboratory study to measure the effects of dynamic changes in light level on target detection performance was conducted. Subjects responded to peripheral targets following the presentation of a light level increase in one part of a visual display or following no change in light level. Even when the target was located in a different part of the display than the location where the light level increase occurred, reaction times were shorter. There were few missed targets under all conditions tested in the study. While the results cannot be directly applied to vehicular lighting situations, they provide some indication that light level changes can affect target detection in ways unrelated to the change in visibility that the light level change induces.

Field Testing of a Wet FGD Additive for Enhanced Mercury Control - Task 3 Full-scale Test Results

This Topical Report summarizes progress on Cooperative Agreement DE-FC26-04NT42309, 'Field Testing of a Wet FGD Additive'. The objective of the project is to demonstrate the use of a flue gas desulfurization (FGD) additive, Degussa Corporation's TMT-15, to prevent the reemission of elemental mercury (Hg{sup 0}) in flue gas exiting wet FGD systems on coal-fired boilers. Furthermore, the project intends to demonstrate whether the additive can be used to precipitate most of the mercury (Hg) removed in the wet FGD system as a fine TMT salt that can be separated from the FGD liquor and bulk solid byproducts for separate disposal. The project is conducting pilot- and full-scale tests of the TMT-15 additive in wet FGD absorbers. The tests are intended to determine required additive dosages to prevent Hg{sup 0} reemissions and to separate mercury from the normal FGD byproducts for three coal types: Texas lignite/Power River Basin (PRB) coal blend, high-sulfur Eastern bituminous coal, and low-sulfur Eastern bituminous coal. The project team consists of URS Group, Inc., EPRI, TXU Generation Company LP, Southern Company, and Degussa Corporation. TXU Generation has provided the Texas lignite/PRB cofired test site for pilot FGD tests, Monticello Steam Electric Station Unit 3. Southern Company is providing the low-sulfur Eastern bituminous coal host site for wet scrubbing tests, as well as the pilot- and full-scale jet bubbling reactor (JBR) FGD systems to be tested. IPL, an AES company, provided the high-sulfur Eastern bituminous coal full-scale FGD test site and cost sharing. Degussa Corporation is providing the TMT-15 additive and technical support to the test program as cost sharing. The project is being conducted in six tasks. Of the six project tasks, Task 1 involves project planning and Task 6 involves management and reporting. The other four tasks involve field testing on FGD systems, either at pilot or full scale. The four tasks include: Task 2 - Pilot Additive Testing in Texas Lignite Flue Gas; Task 3 - Full-scale FGD Additive Testing in High-sulfur Eastern Bituminous Flue Gas; Task 4 - Pilot Wet Scrubber Additive Tests at Plant Yates; and Task 5 - Full-scale Additive Tests at Plant Yates. The pilot-scale tests were completed in 2005 and have been previously reported. This topical report presents the results from the Task 3 full-scale additive tests, conducted at IPL's Petersburg Station Unit 2. The Task 5 full-scale additive tests will be conducted later in calendar year 2007.
GAME ACTION EFFICIENCY ON VOLLEYBALL GAME STRUCTURES ACCORDING TO THE OPPONENTS’ LEVEL

Performance volleyball is composed of two fundamental game structures, namely: structure I (at own service), which includes as game actions the service, block, dig, pass and attack, and structure II (at service reception), which is made up of game actions from service, pass, attack, block and dig. This study highlights the differences between the efficiency indices of game actions on game structures at the Știința Bacău team depending on the opponents’ level. This is based on analysing the performance of the teams during the Romanian National Women’s Volleyball Championship, 1st Division, which consisted of 18 games, out of which 10 games with level 1 teams and 8 games with level 2 teams. The research hypothesis aimed at verifying the dependence of the efficiency indices of game actions on game structures according to the opponents’ level. The subjects of this study were the players of the Știința Bacău team in the 2017-2018 season. As a result of this study, we have found that there are statistically significant differences between the efficiency indices of game actions on game structures according to the opponents’ level for service (p = 0.047) and dig (p = 0.006) in structure I and for attack (p = 0.015) in structure II, which confirms the hypothesis of our research.
Strength, sorptivity and carbonation in blended OPC-GGBS, alkali activated slag, and fly ash based geopolymer concrete

Several studies have shown that alkali activated binders can achieve similar strengths to both ordinary Portland cement (OPC) and blended cements. However, to date little research has been undertaken on their durability properties. This study investigated the influence of activators concentration and alkali modulus on strength, sorptivity and carbonation of alkali activated slag (AAS) and fly ash (FA) based geopolymer concrete. The same tests were also conducted on blended concrete with 30%, 50%, and 70% OPC replacement with ground granulated blast-furnace slag (GGBS) along with control concrete. Results indicate that the alkali modulus has a major effect on sorptivity of both AAS and geopolymer, however no significant effects of the alkali modulus on carbonation was observed on AAS concrete. The phenolphthalein indicator gave no clear indication between carbonated and non-carbonated area in geopolymer specimens. The sorptivity of blended concrete reduced but Ihe carbonation increased as the replacement level increased.
Implementing Smart Controllers on Single-Family Homes with Excessive Irrigation

AbstractIn this study, smart irrigation controllers were targeted toward single-family potable water customers in Orange County, Florida with excessive landscape irrigation patterns. Out of five treatments, four treatments received either an evapotranspiration controller (ET) or soil moisture sensor (SMS) controller, installed by a contractor, but two technology treatments included an educational program (+Pgm) component. The fifth treatment was a comparison treatment (MO) with no interventions to their normal irrigation scheduling methods. After 22 months of evaluation, both +Pgm treatments reduced irrigation application, ranging from 21 to 52%. However, none of the treatments performed with high efficiency in all seasons. Only a few treatments were able to maintain irrigation totals within a gross irrigation requirement (GIR) range from 60 to 100% efficiency. The technology treatments that participated in the customized educational program were more likely to achieve additional reductions in irrigation .
DRIVING BEHAVIOUR IN A REAL AND A SIMULATED ROAD TUNNEL

The aim was to validate driving behaviour in a simulated road tun Speed and lateral position of 20 subjects were measured in a real tunnel and in the same tunnel implemented in the VTI Driving Simulator. Driving speed was higher in the simulated tunnel than the real tunnel. Elimination of speed information from the speedometer caused a small speed increase in both situations. Als the difference between driving lanes was similar in both cases. T effects on speed variation was similar to that for speed level. Regarding lateral position, subjects positioned themselves somewh further away from the nearest tunnel wall in the real tunnel than the simulated tunnel. In both situations the distance to the near wall was greater when it was located to the left of the driver th on the opposite side. Lateral position deviation was about the sa when the road was straight, but on a curved section it was somewh greater for the simulated tunnel. Subjects reported that they fou it somewhat more difficult to keep the chosen speed in the simula tunnel. Other subjective differences between the real and the simulated tunnel were small. It is concluded that behavioural validity in absolute terms was not quite satisfactory, especially regarding choice of speed, whereas relative validity was good for both speed and lateral position.

Smartphone usage pattern for science teachers: The case of Zimbabwe

: Smartphones are new generation educational tools usable by science teachers for both socialization and communication, and academic use. Concern is however on how such devices are used by the teachers who are central to curriculum implementation. The study was therefore carried out to establish the characteristics of science teachers’ interactions with their devices (usage patterns) in Zimbabwe. The User Gratification Theory guided the descriptive survey design from a quantitative research approach that was employed in collecting and analyzing data, collected through the Kobo Toolbox online survey application. The findings show that smartphone use is more popular for socialization and communication than for academic purposes and the usage patterns vary with age. Late career science teachers use smartphones mainly for socialization and communication while accessing social media and leisure material are very popular with the early career science teachers. Smartphones are also popular as ‘pocket libraries’ for early career science teachers while reading news is popular with the late career science teachers.
Impact of technostress on job satisfaction and organizational commitment : a thesis presented in partial fulfillment of the requirements for the degree of Master of Management (Management) at Massey University, Auckland, New Zealand / Ian Hyslop

Due to the fast development of ICT technology, both ur private and professional lives have changed fundamentally. By using mobile c omputing communication devices and computer networks, people have the abil ity to access information quickly; real-time information sharing with colleagues that c n happen anytime and anywhere. Thus employees may feel forced to be always connect ed and respond to work-related issues at any time, and so lose the control of thei r personal lives. With the adoption of ICTs, organizations are taking on the pressures of frequent re-engineering and process changes, driven by the ICT changes and upgrades. Al though the evolution of ICTs has brought numerous potential benefits to the organiza tion, employees often feel frustrated and distressed when they are not able to cope with the demands of organizational computer usage. Recent literature ha s named this technology-related stress “technostress”. The primary objective of the present study is to de velop and validate a model that analyzes the effects of factors that create technos tress, and examines its relationship with job satisfaction and organizational commitment . I addition, this study also attempts to identify a mechanism that can potential ly al eviate the negative effects of technostress. It examines how user involvement as a technostress inhibitor affects technostress, job satisfaction and organizational o utcomes.
