description: We have tried to interpret the physical role of the three-tangle and $π$-tangle in the real physical information process. For the model calculation we adopt the three-party teleportation scheme through the various noisy channels. The three parties consist of sender, accomplice and receiver. It is shown that the $π$-tangles for the X- and Z-noisy channels vanish at $κt \to \infty$ limit, where $κt$ is a parameter introduced in the master equation of Lindblad form. In this limit the receiver's maximum fidelity reduces to the classical limit 2/3. However, this nice feature is not maintained at the Y- and isotropy-noise channels. For Y-noise channel the $π$-tangle vanishes at $0.61 \leq κt$. At $κt = 0.61$ the receiver's maximum fidelity becomes 0.57, which is much less than the classical limit. Similar phenomenon occurs at the isotropic noise channel. We also computed the three-tangles analytically for the X- and Z-noise channels. The remarkable fact is that the three-tangle for Z-noise channel is exactly same with the corresponding $π$-tangle. In the X-noise channel the three-tangle vanishes at $0.10 \leq κt$. At $κt = 0.10$ the receiver's fidelity can be reduced to the classical limit provided that the accomplice performs the measurement appropriately. However, the receiver's maximum fidelity becomes 8/9, which is much larger than the classical limit. Since the Y- and isotropy-noise channels are rank-8 mixed states, their three-tangles are not computed explicitly. Instead, we have derived their upper bounds with use of the analytical three-tangles for other noisy channels. Our analysis strongly suggests that we need different three-party entanglement measure whose value is between three-tangle and $π$-tangle.

description: The current study examined the level of participation by families who have Vlll been involved between 1 and 3 years with the Community-Family Partnership (CFP) project. The CFP project is 1 of 34 Comprehensive Child Development Projects funded by the Administration for Children, Youth, and Families through the Head Start Bureau. The CFP makes available comprehensive, on-going services to enrolled families. Twenty-six families were identified as the Low Participation Group . Twenty-three families were identified as the High Participation Group. Children from each group were tested using the Battelle Developmental Inventory on a yearly basis. Results of a repeated measures ANOV A indicated that children of families with high participation had better child BDI scores than children of families with low participation. No difference was found in the economic status of these families. Multiple regression analyses were conducted using family demographic characteristics and other measures to create a profile of an actively participating family.

title: The Efficacy of Level of Adjunct Questions over Time by Discourse Type
Creators: name: Zhang, Ying
Publisher: name: Utah State University
Year: 1993

description: The potential differential effects of discourse type on the study of adjunct question efficacy were examined. The interaction among discourse type, question level, and time of test was investigated as reflected by readers' intentional and incidental learning outcomes. Eighty-four undergraduate students enrolled in an introductory psychology course were randomly assigned to four experimental conditions: (a) texts with low-order questions, (b) texts with high-order questions, (c) texts with both low- and high-order questions, and (d) texts with no questions. Each subject read both the narrative text and the expository text. The dependent measure was composed of five subscales of the criterion test, focusing on the relation between levels of questions and levels of importance in the queried information. Immediate and seven-day delayed testing results were examined using multivariate analysis of variance repeated measures, simple main effects analysis, Newman-Keuls multiple comparison, and paired t tests.
Adjunct questions were found to be more facilitative for comprehending the expository text than for the narrative text at the college level. An interaction among discourse type, question level, and time of test was found. The effects elicited by low-order questions increased over time in the expository text, but declined rapidly in the narrative text, whereas effects induced by high-order questions remained stable in the narrative text, but declined significantly in the expository text over time. In addition, intentional learning was less susceptible to the time effect than incidental learning for both types of text. On most measures, subjects provided with low-order questions outperformed those provided with high-order questions. The study suggests that the differential effects of adjunct questions might be a function of the combined force of discourse type, question level, and time of test; further research is needed to explore the relative efficacy of adjunct questions of different levels.
title: The Prevalence of Dual Diagnosis of Generalized Anxiety Disorder and Alcoholism in the Literature: A Critical Meta-Analytic Review
Creators: name: Stone, Joseph B.
Publisher: name: Utah State University
Year: 1993

description: The relationship between alcoholism and generalized anxiety disorder (GAD) has been discussed in two research areas: research on the prevalence of GAD in alcoholics, and the prevalence of alcoholism in individuals diagnosed with GAD. Studies indicate that between 6 to 26% of alcoholics have a current diagnosis of GAD, with a lifetime prevalence rate of up 51%. In the general population, 4% would currently receive a diagnosis of GAD, with a lifetime prevalence of 8%.
This meta-analytic review of the empirical literature examines the relationship between GAD and alcoholism. The author used percentages to compare the results of various studies. The averaged results of these various studies suggested there is a 25% comorbidity rate of GAD and alcoholism. critical review of the studies examined in this review revealed substantial methodological errors. Based on a critical review of the research methodology in the studies cited, the author proposed further research.

description: The scalar $f_{xc}$ and tensor $\hat{f}_{xc}$ exchange-correlation (xc) kernels are key ingredients of the time-dependent density functional theory and the time-dependent current density functional theory, respectively. We derive a comparatively simple relation between these two kernels under the assumption that the dynamic xc can be considered "weak". We expect our formula to serve as a convenient bridge between the scalar $f_{xc}$ which directly enters many applications and the tensor $\hat{f}_{xc}$ which, due to its locality in space, is much easier to approximate.

title: Lack of Control as a Predictive Factor for Stress-related Symptoms in Rape Victims
Creators: name: Sombke, Chad
Publisher: name: Utah State University
Year: 1993

description: Researchers have agreed that most rape victims vii experience stress-related symptoms similar to post-traumatic stress disorder. There have also been numerous studies that have tried to predict the severity of those stress-related symptoms, but the literature is inconclusive. Lack of perceived control is consistently mentioned in the rape research literature as being present in rape victims, but no study has empirically examined the relationship between perceived control and a rape victim's stress-related symptoms.
The purpose of this study was to empirically examine the relationship between perceived control and stress-related symptoms in rape victims. This was accomplished by comparing a group of 33 subjects who reported being victims of rape with a group of 50 subjects who did not report being victims of rape. Mean stress-related symptom scores were correlated with perceived control scores; also, factors, including group membership and the time elapsed since a rape, were regressed onto the subjects' stress-related symptom scores.
The correlations between stress-related symptoms and perceived control in the rape victim group were statistically significant, but the relationship was not present for the nonvictim group. Also, nonsignificant results were obtained for joint effects between perceived control and group membership, along with perceived control and time since a victim had been raped.
The results suggest that low perceived control is a good predictor for elevated stress-related symptoms. Further research may clarify the relationship between perceived control and stress-related symptoms in rape victims.

description: Strongly anchored free-standing smectic films usually present a stepwise reduction of the number of layers when the temperature is raised above the smectic-isotropic bulk transition temperature. Here, we demonstrate that a field-induced layer thinning transition can take place in smectic films with a negative dielectric anisotropy even below the bulk transition temperature. Using an extended McMillan's model, we provide the phase diagram of this layering transition and show that, when the field is raised above the bulk transition field, the film thickness reduction is well described by a power-law with an exponent that depends on the temperature and the aspect ratio of the liquid crystal molecule.

title: More Money for Some: The Redistributive Effects of Open Market Operations
Creators: name: Bustamante, Christian
Publisher: name: Bank of Canada
Year: 2021

description: "Open market operations are among the most common instruments that central banks use to conduct monetary policy. However, there is little understanding about how these operations can unevenly affect households with different portfolio compositions and levels of wealth.

I study how monetary policy is transmitted through open market operations and what this means for different households along the distribution of wealth. In my model, heterogeneous households save using both money and government bonds while facing random liquidity needs. I show that open market operations that increase the supply of government bonds are associated with higher nominal interest rates and increased economic activity.

A higher supply of bonds improves households’ ability to insure against future liquidity needs.  It also leads to more efficient trading between households and therefore reduces inequality. Moreover, this type of operation redistributes wealth from rich to poor households and raises consumption and welfare among households with lower levels of wealth."

description: "Les opérations d’open market font partie des instruments les plus couramment utilisés par les banques centrales pour mener la politique monétaire. Toutefois, on comprend mal comment elles peuvent toucher les ménages de manière inégale selon la composition de leur portefeuille et leur richesse.

J’étudie la transmission de la politique monétaire par la voie des opérations d’open market et les implications de ces dernières sur différents ménages en fonction de leur richesse. Dans mon modèle, des ménages hétérogènes épargnent en détenant des espèces et des obligations d’État et ont des besoins aléatoires en liquidités. Je montre que les opérations d’open market qui augmentent l’offre d’obligations d’État sont associées à une hausse des taux d’intérêt nominaux et de l’activité économique.

L’augmentation de l’offre d’obligations permet aux ménages de mieux répondre à de futurs besoins en liquidités. Elle améliore aussi l’efficacité des transactions entre ménages, ce qui réduit les inégalités. De plus, ce type d’opérations d’open market entraîne une redistribution de la richesse des riches vers les pauvres ainsi qu’accroît la consommation et le bien-être des ménages moins bien nantis."

Year: 1994

description: This study was conducted to continue the investigation of apparent differences in cognitive ii abilities between Navajo Indian children and non-Navajo children. Subjects were 248 second-grade students, ranging from 7 to 9 years old. The Navajo sample lived in the Shiprock, New Mexico, area of the Navajo Indian Reservation, and the non-Navajo sample lived on the east side of Salt Lake City, Utah. Data were collected using six tests designed to measure spatial abilities in primary grade children. Results indicated that the non-Navajo children scored significantly higher on two individual tests and on the total test score under timed conditions, with no differences between groups when timing was not a factor. Two factors were identified for both groups. Factor loadings were different between the groups. As the scoring moved from timed to extended time, it changed for the nonNavajo children but remained the same for the Navajo group. Discriminate function analysis indicated a moderate ability to predict group membership using these tests. Gender differences were noted as well, with females scoring significantly lower than males on timed but not on extended time. Some race/gender interactions also were recorded. Suggestions were made that differences may be related to varying strategies used by not only different racial groups but by both genders as well. The within-group variability indicated a need for investigation of individual differences as well as group differences. Suggestions included using a greater number of instruments, an exploration of strategies, and using a examiner familiar to the students.
title: Family Perspectives of the Professional-Paraprofessional Partnership Model of Home-Based Early Intervention Service Delivery
Creators: name: Walters, Amy Sanford
Publisher: name: Utah State University
Year: 1994

description: Current legislation regarding early intervention services has focused on the family unit, rather than the individual child, as the recipient of services. A model of family-centered care has been adopted and as a result, new models for service delivery have been developed. The present study examined family perspectives of the professional-paraprofessional partnership model, and assessed the ecological validity of this model as it relates to the basic principles of family-centered care. Families who participated in an early intervention program that utilized the professional-paraprofessional partnership model were interviewed upon program completion. Families reported receiving a wide range of child and family services, as well as assistance from their home visitor in accessing formal and informal resources within their community. Families recognized and positively responded to visitors who were flexible, supportive, and respectful of their family. A positive relationship was found between the number of family services received and ratings of the home visitor on variables of flexibility, support, and control. The majority of families described the home visiting service as the most helpful service they received. In addition, there were no differences in the services provided by professional and paraprofessional visitors, as reported by families. Overall, family reports indicated parent satisfaction with the professional-paraprofessional partnership model, and this model was found to meet the proposed family-centered objectives for early intervention services.

Publisher: name: Utah State University
Year: 1994

description: The Daily Assessment Form (OAF) retrospectively assessed symptoms of late luteal phase dysphoric disorder (LLPDD), both at the beginning and at the end of a 2-month time interval. Ninety-four women between the ages of 18 and 45 entered the study. Half of the subjects viewed a negative-case, stereotypic presentation of LLPDD prior to the pretest. sixty-eight subjects qualified on the pretest to complete the study. Half of the remaining no-case subjects and half of the remaining negative-case subjects completed 8 weeks' prospective ratings via the OAF. Forty-eight subjects remained to complete the posttest at the end of that time interval. Pretest Total and Pretest Criteria scores revealed significant main effects for case-presentation condition (E[l,63] = 7.08, R = .01) and (E[l,63] = 8.34, R = .01) and completion level (E[l,63] = 6.76, R = .01) and (E[l,63] = 3.76, R .06). Effect sizes equalled 0.48 and 0.45 for case presentation and 1.92 and 1.98 for completion.

description: Parametric amplification of vacuum fluctuations is crucial in modern quantum optics, enabling the creation of squeezing and entanglement. We demonstrate the parametric amplification of vacuum fluctuations for matter waves using a spinor F=2 Rb-87 condensate. Interatomic interactions lead to correlated pair creation in the m_F= +/- 1 states from an initial unstable m_F=0 condensate, which acts as a vacuum for m_F unequal 0. Although this pair creation from a pure m_F=0 condensate is ideally triggered by vacuum fluctuations, unavoidable spurious initial m_F= +/- 1 atoms induce a classical seed which may become the dominant triggering mechanism. We show that pair creation is insensitive to a classical seed for sufficiently large magnetic fields, demonstrating the dominant role of vacuum fluctuations. The presented system thus provides a direct path towards the generation of non-classical states of matter on the basis of spinor condensates.

Year: 1994

description: The study examined whether, under comparable testing conditions, second - v and fourth-grade students who took a computer-administered (CA) achievement test in mathematics achieved the same mean score as comparable students who took the same test by paper and pencil (PP).
For number correct, the CA standardized mean difference effect size was - 0 .28, which was larger than the expected effect size of zero, although not statistically significant at. 05. It was noted that CA subjects completed the test more quickly, on the average, than PP subjects (CA effect size for time to completion = - 0. 79). When time to completion was statistically controlled, the difference in mean scores between CA and PP modes vanished (CA effect size = - 0.02).
Possible explanations for the findings are discussed. It is concluded that, based on these results, one would not be justified in assuming CA and PP scores from elementary school students to be equivalent.

description: Within the last 5 years, researchers have given increased attention to preschool assessment. One test, the Battelle Developmental Inventory, has become increasingly popular for use with preschool-age children. Despite its frequent use by early intervention programs, few researchers have studied the technical adequacy of the Battelle. The predictive validity of the Battelle was examined, using 154 children with disabilities. Scores on the Battelle for children 3 to 5 years of age were compared with scores on the Scales of Independent Behavior administered to the same children 2 to 3 years later. Moderate to strong relationships were found between the scores. Scores on the Battelle motor domains appeared to correlate the strongest with the Scales of Independent Behavior Total score. In general, the Battelle appeared to be a useful measure for predicting future performance on the Scales of Independent Behavior.

Year: 1993

description: The study and measurement of attitudes toward racial and ethnic groups are important parts of the field of cross-cultural psychology. The present study examined a theory of racial attitudes, that of symbolic racism, and several demographic variables. The sample population consisted of 575 Caucasians and 122 Far-East Asian college students. Results indicated that Symbolic Racism is a unique theoretical construct, that Caucasian students were less racially biased than their Asian peers, and that group differences in racial attitudes existed across religious affiliation, number of reported interracial friendships, and gender.
Electrochemical behaviour of platinum-iridium anodes

Publisher: name: University of British Columbia
Year: 2011

description: This thesis considers the electrochemistry of platinum-iridium electrodes in both sulphate- and chloride-containing electrolytes at 20 - 25°C. Both wire electrodes of appropriate alloy compositions and titanium-substrate electrodes were employed. Polarization curves were obtained, and a technique for measuring the surface area of the electrodes was employed in order to determine the effect of potentiostatic electrolysis on the electrochemically active area. The wire alloy electrodes showed polarization behaviour in 1M NaCl; pH 2 identical to that of platinum electrodes, indicating that iridium is not effective in reducing the passivation of these electrodes even with up to 25% alloy content. The coated electrodes showed irreversible surface area losses in both sulphate and chloride electrolytes, with the latter producing significant reductions after very short polarization times. It is suggested that oxidation of the substrate leading to electrical isolation of coating plates is responsible for the area decay.

title: The Role of Gender Differences in the Relationship Between Guilt- and Shame-Proneness and Depressive Symptomatology
Creators: name: Shiffler, Julie Bingham
Publisher: name: Utah State University
Year: 1993

description: The purpose of this study was to examine the role played by gender in the relationship between the degree of depressive symptomatology and levels of adaptive guilt-, maladaptive guilt-, and shame-proneness in a college population. A measure of depressive symptomatology (the Beck Depression Inventory) and a measure of guilt- and shame-proneness (the Self-Conscious Affect and Attribution Inventory - Revised) were administered to 299 college students (113 males and 186 females). Females reported higher total levels of depressive symptomatology than males. Statistically significant gender differences were found for nine BDI items. Females also had higher levels of adaptive guilt-, maladaptive guilt-, and shame-proneness. However, correlations among the three emotion variables and levels of depressive symptomatology were generally low, and the correlations for males were higher than those for females. The percentage of variance in depression accounted for by the emotion variables was also low. However, the hypothesized relationships were found in preliminary results from the 19 subjects with depression scores greater than 18, and implications for future research were discussed. The results were compared to past research on gender differences in depression in college populations, as well as previous research relating guilt- and shame-proneness to depression. The socialization of gender differences in guilt- and shame-proneness was also discussed.
A novel application of non-invasive microelectrode ion flux measuring technique in food microbiology
Creators: name: Shabala, SI
Publisher: name: University Of Tasmania
Year: 2023

description: At present, both the control of bacterial growth to ensure food safety, and the balancing of nutritional requirements and optimization of culture growth conditions for beneficial food microorganisms, are essentially empirically based. An alternative time- and money-saving approach to this implies a better understanding of the physiological processes underlying the cellular response to the applied treatment. In the present work, the non invasive microelectrode ion flux measuring technique (MIFE¬¨vÜ) was first introduced in food microbiology, to address some of the above issues and to shed some light on adaptive responses of bacterial and fungal cells to environmental change. Several \case studies\" were undertaken to explore the utility of the MIFE technique to study of adaptive responses in a variety of microorganisms. First various methodological aspects of ion-flux measurements in microorganisms were addressed. These included the issue of cell immobilisation specific details of culture growth and preparation and potentially confounding effects of environmental \"hurdles\" on measuring electrodes such as ionic strength of solution pH etc. Second a marine protist thraustochytrid ACEM C proposed as a valuable single source of polyunsaturated fatty acids was used to demonstrate the applicability of the MIFE technique to understanding the physiology of growth and adaptive responses at the single cell level. Various aspects of membrane-transport processes associated with thraustochytrid cell growth and development as well as its adaptive responses to osmoticurn temperature and nutritional status were studied. Third in a pioneering application of the MIFE technique to bacterial cells adaptive responses of immobilised bacteria of different genera were studied at the population level. The major emphasis was on Listeria monocytogenes and Escherichia coli two physiologically contrasting organisms of great economic importance to food microbiology. The adaptive responses were studied in relation to acid stress bacteriocin (nisin) action and substrate availability. Finally an investigation was made into the feasibility and utility of combining the MIFE technique with another method and study of bacterial adaptive responses specifically fluorescence Ratio Imaging Microscopy (FRIM) L. monocytogenes responses to acid stress were used as a case study. Overall this study showed for the first time that the application of the MIFE technique to study membrane-transport processes in food-related rilicroorganisms might lead to significant conceptual advances in the understanding of the mechanisms underlying growth and adaptive responses of bacterial and fungal cells and could contribute to reducing food-borne infections or towards improved productions of nutritionally important compounds."

description: We utilize high-resolution (R~60,000), high S/N (~100) spectroscopy of 17 cool Pleiades dwarfs to examine the confounding star-to-star scatter in the 6707 Li I line strengths in this young cluster. Our Pleiads, selected for their small projected rotational velocity and modest chromospheric emission, evince substantial scatter in the linestrengths of 6707 Li I feature that is absent in the 7699 K I resonance line. The Li I scatter is not correlated with that in the high-excitation 7774 O I feature, and the magnitude of the former is greater than the latter despite the larger temperature sensitivity of the O I feature. These results suggest that systematic errors in linestrength measurements due to blending, color (or color-based T_eff) errors, or line formation effects related to an overlying chromosphere are not the principal source of Li I scatter in our stars. There do exist analytic spot models that can produce the observed Li scatter without introducing scatter in the K I line strengths or the color-magnitude diagram. However, these models predict factor of >3 differences in abundances derived from the subordinate 6104 and resonance 6707 Li I features; we find no difference in the abundances determined from these two features. These analytic spot models also predict CN line strengths significantly larger than we observe in our spectra. The simplest explanation of the Li, K, CN, and photometric data is that there must be a real abundance component to the Pleiades Li dispersion. We suggest that this real abundance component is the manifestation of relic differences in erstwhile pre-main-sequence Li burning caused by effects of surface activity on stellar structure. We discuss observational predictions of these effects.

Repository

description: This deliverable presents a web-based tool which acts as a repository of international good practices on research impact assessment and measurement. The Deliverable describes the process leading to the repository set-up, covering the web-based tool development, the generation of contents and resources identification, as well as future steps.

The repository brings together in a single place good practices of impact assessment and measurement, both in the context of ENLIGHT Universities and worldwide. It is expected to allow mutual learning on research impact by enabling open debate and discussion between ENLIGHT university academics and staff, and also external experts. As such, it will help ENLIGHT universities to raise impact awareness, to acquire impact literacy and to develop impact readiness, contributing thus to promote a culture of impact both within and beyond ENLIGHT.

The web-based tool is available at this link impact.enlight-eu.org and is expected to be a live platform which is updated on a six-monthly basis.

Diagrams and transforms applied to convex polytopes
Creators: name: Lockeberg, Erik Ring
Publisher: name: University of British Columbia
Year: 2010

description: The aim of this paper is to present a unified treatment of diagram techniques, particularly as applied to problems concerning convex polytopes. An attempt is made to summarize new results (listed below) of M. Perles, G.C. Shephard and P. McMullen. A diagram technique is one of several methods for associating to a finite subset of a finite-dimensional Euclidean space a finite subset of the same cardinality in another Euclidean space, in general of a different dimension. The second subset is a "diagram" or "transform" of the original set. The original set and its diagram are seen to be related in a symmetrical way to the kernel and image respectively of a certain linear map. A problem concerning a finite set corresponds to a problem concerning the diagram which may be easier to solve, particular if the diagram is of low dimension. Gale diagrams are used to enumerate d-polytopes with d+3 vertices, to construct an 8-polytope not rationally imbeddable, to investigate the symmetry group of polytopes and to obtain results concerning projectively unique polytopes. It is shown how positive diagrams may be used to investigate positive bases of Euclidean space. Zonal diagrams are used to investigate the neighbourliness of centrally symmetric polytopes. A diagram technique for dealing with polyhedral sets, including linear systems and metric properties of polyhedral sets. A geometric interpretation of the affine transform, central transform and zonal diagram in terms of regular polytope is given.
title: The Relationship Between Perceived Parenting Styles and Adolescent Locus of Control and Self-Concept
Creators: name: McClun, Lisa Ann
Publisher: name: Utah State University
Year: 1993

description: Relationships between adolescents' perceptions of their parents' responsiveness and demandingness, adolescents' locus of control orientation, and adolescents' self-concept ratings were investigated. Subjects included 198 students from a middle school in northern Utah. Subjects were given the Nowicki-Strickland Internal-External Control Scale for Children, the Harter Self-Perception Profile for Adolescents, and the Perceived Parenting Style Survey.
Results indicated that subjects who perceived their parents as being authoritative had significantly (p < .001) more internal locus of control scores than subjects who reported either the permissive or authoritarian styles. Also, self-concept scores were significantly higher (p < .001) for the authoritative group than the authoritarian group on the Self-Perception Profile for Adolescents subscales of Scholastic Competence, Social Acceptance, Physical Appearance, Behavioral Conduct, Close Friendship, and Global Self Worth. The permissive group reported significantly lower scores (p < .05) on the subscales of Scholastic Competence and Behavioral Conduct. There was also a significant negative correlation (p < .001) between locus of control scores and the subscale scores on the Self-Perception Profile for Adolescents.
Although there were some limitations in the study methodology, the significant differences found between the groups indicated that the authoritative parenting style positively correlates with higher self-concept and internal locus of control, while the authoritarian parenting style negatively correlates with self-concept and internal locus of control.

Subjects: software citation, research credit, research software, RSE, research software engineering

description: Academia is a reputation economy: careers succeed or fail based on a shared perception of the scale of contributions. The Alan Turing Institute is a research institute with a mission both to contribute to scholarship, and to deliver real-world economic and social impact, much of which is realised in software. This lecture reflected on life as a “middle author scientist”, considered the contributions to research of those who deliver “too much code and not enough papers”, and considered models for alternative academic careers, and tweaks to the academic system of social credit, which incentivise collaboration and balance scholarship and service.
Factors influencing use of e-commerce services of online access centres by Tasmanian micro businesses
Creators: name: Shabaneh, Atef
Publisher: name: University Of Tasmania
Year: 2023

description: The purpose of this research study was to investigate the success of Online Access Centres in attracting micro business operators in their local communities to adopt online technologies. To answer the research question, a quantitative research approach was adopted, which involved the utilisation of a self-administered web-based questionnaire. Due to the many barriers to the uptake of e-commerce small businesses are facing, small businesses in rural Tasmania (especially micro-sized) can benefit from the services of Online Access Centres (OACs). Online Access Centres run general awareness and educational programs and affordable web development and hosting services to address the common barriers to the uptake of e-commerce facing small businesses such as lack of awareness and fear of setup and management fees. Different industry sectors' usage of Online Centres and facilities reflects certain characteristics of industries that have heavier reliance on information than other industry sectors and are more likely to benefit from online technologies. The extent to which centres are able to encourage small businesses to adopt online technologies depends on the adequacy of OACs resources and facilities and the marketing approach (strategies) of OACs.
title: Heat Transfer Analysis of Localized Heat-Treatment for Grade 91 Steel
Creators: name: Walker, Jacob D.
Publisher: name: Utah State University
Year: 2017

description: Many of the projects utilizing Grade 91 steel are large in scale, therefore it is necessary to assemble on site. The assembly of the major pieces often requires welding in the assembly; welding drastically changes the superior mechanical properties of Grade 91 steel that it was specifically developed for. Therefore, because of the adverse effects of welding on the mechanical properties of Grade 91, it is necessary to do a localized post weld heat treatment.
In this study a localized post weld heat treatment is used to gather experimental data. The data is then used to derive unknown heat transfer coefficients that are necessary for theoretically modeling heat treatments. With the derived coefficients that have been found one can theoretically model heat treatment scenarios specific to the situations and provide results that are reliable and provide insight as to what parameters will provide the best results.
This research is very beneficial to the joining of metals industry because it provides a way to ensure the method used to heat treat the welded section is being properly done, and the required heat treatment is achieved. It is applicable to many different geometries so that it can be modified to specific situations.
