Marketing with Twitter : investigating factors that impact on the effectiveness of tweets

The increasing use of Twitter by businesses has created the challenge of how organisations can use Twitter most effectively for marketing. Using data across several years of Twitter activity by both leading global brands and a non-profit organisation (NPO), this thesis presents measures that can be used by practitioners and researchers to assess the effectiveness of marketing communications on Twitter. It discusses the factors that predict consumer and stakeholder engagement with organisational tweets, and different Twitter strategies that have been successfully (and less successfully) used by leading global brands and a large non-profit organisation. The thesis consists of four separate but inter-related papers that have variously been published or accepted for publication. Each paper analyses different aspects of organisational Twitter activity, including an analysis of tweet features that impact on the frequency of retweeting of brands’ tweets and examination of reciprocity within the network of an NPO and its corporate partners. The thesis contributes to the literature by assessing what has been done on Twitter, what works and what does not, and by showing what it is possible to achieve on the platform in terms of effective communications. Firstly, the research evaluates Twitter activity both in commercial organisations and within the network of an NPO and its supporters by analysing their Twitter accounts’ activity, follower engagement and tweet structure. The research also compares and contrasts Twitter activity over a two-year period by both commercial brands and an NPO and therefore provides insights into the evolution of Twitter use. Secondly, the research develops and tests a theoretical model that predicts electronic word-of-mouth (eWOM) on Twitter by assessing the effect of different tweet features on retweet count. The
Intellectual capital research and practice: 7 myths and one golden rule

Abstract The intellectual capital research and practice entered in the last years into a visible decline due to some barriers in understanding its intangible nature and designing Newtonian metrics for its measurement and reporting. Inertial thinking is very powerful in promoting new approaches for the need of a new perspective in working with intellectual capital. Unfortunately, even some top journals in the domain of intellectual capital remained trapped into this Newtonian logic and standard statistical analysis, as a result of the mind-set of their editorial staff and reviewers. The purpose of this paper is to present a critical analysis of the intellectual capital research and practice today and to reveal some of the most important barriers in understanding the complexity and nature of the intellectual capital. These barriers manifest like myths in approaching the research into intellectual capital, myths that create a false reality and false research questions, which enter into collision with the real life of companies and their business. The paper identifies seven myths which created a Newtonian version of the non-Newtonian reality, and a golden rule for further research into the intellectual capital of organizations. The conclusion of the present critical analysis is that we need a new approach to understand the complexity of the intellectual capital and new metrics to measure it.
Los efectos de la política fiscal sobre el consumo privado: nueva evidencia para el caso español

Este trabajo analiza si la hipotesis de neutralidad de la politica fiscal (teorema de equivalencia Ricardiana) puede considerarse como una aproximacion valida para la realidad economica espanola o si, por el contrario, existen desviaciones (y de que tipo) de dicha situacion, lo que estaria mas en la linea del enfoque Keynesiano convencional acerca de los efectos de la deuda sobre las decisiones de consumo-ahorro privados. La investigacion intenta aportar nueva evidencia sobre la escasa literatura empirica que en Espana ha considerado esta cuestion. El analisis que se realiza se basa en datos agregados de caracter anual para Espana que abarcan los anos 1955 a 2000, y utiliza tanto el enfoque estructural como el de ecuaciones de Euler para los contrastes de la hipotesis de neutralidad.
Mining online reviews in Indonesia's priority tourist destinations using sentiment analysis and text summarization approach

In this modern era, online hotel reviews have a big role considering the hotel is one of the aspects in determining the competitiveness in the tourist area, but its implementation is still rare. Regarding the government's plan to increase tourist arrivals to Indonesia, this research utilized text mining towards online hotel reviews to find useful knowledge in building the hospitality sector as an integral part of the tourism industry. Text classification technique was used to obtain sentiment information contained in review sentences through sentiment analysis, as well as clustering technique as a part of text summarization to find representative sentences that are able to describe the entire contents of the review. The main contribution of this research is to combine two techniques in text mining that have never been done before, namely the sentiment analysis and text summarization. Experiments with hotel reviews in Labuan Bajo and Bali generated surprising outcomes, where the accuracy of classification model reaches 78% and the Davies-Bouldin Index (DBI) of clustering algorithm strikes 0.071. The output of this research is expected to describe the condition of the hotel in the tourist area with a different level of tourism development so that it can contribute to improving the quality of the hotel industry as well as supporting the tourism industry in Indonesia.
MARINE RESERVES AND OCEAN NEIGHBORHOODS: The Spatial Scale of Marine Populations and Their Management

▪ Abstract The movement of individuals defines a spatial neighborhood that can help determine marine management strategies. Here, I briefly review four fields of marine biology that each differentially illuminate the scale of marine neighborhoods: effects of marine reserves, tagging studies, microchemistry, and population genetics. These suggest adult neighborhood sizes for many demersal fish and invertebrates as small as kilometers and up to 10 to 100 km. Larval dispersal may be shorter than previously suspected: neighborhood sizes of 10 to 100 km for invertebrates and 50 to 200 km for fish are common in current compilations. How can small reserves protect such species? One conceptual framework is to set reserve size based on adult neighborhood sizes of highly fished species and determine spacing of a reserve network based on larval neighborhoods. The multispecies nature of fisheries demands that network designs accommodate different life histories and take into account the way local human communities us.
Diagnostic and Prognostic Value of Gated SPECT MIBI Early Post-Stress Imaging in Patients With Intermediate Duke Treadmill Score

Purpose of the ReportThe aims of this study were to compare perfusion and functional parameters between early (ES) and standard (SS) post-stress gated SPECT MIBI, to validate ES against coronary angiography, and to determine whether ES parameters can predict future cardiac events. Patients and MethodsThe sample included 63 patients with normal or mildly impaired left ventricular function and intermediate Duke Treadmill Score. They underwent a 2-day stress-rest gated SPECT MIBI with the post-stress data acquired at 15 minutes (ES) and 60 minutes (SS) after i.v. injection of 740 MBq of 99mTc-MIBI. The ES findings were compared to SS and against coronary angiography to determine their sensitivity/specificity for detecting >70% stenosis. The information about new-onset cardiac events was collected 26 ± 6 months later. ResultsPerfusion parameters did not significantly differ between ES and SS. Ejection fraction was significantly lower and regional wall motion abnormalities were significantly higher on ES than SS. The corresponding perfusion and functional parameters were strongly related (linear regression slope 0.65–1.00, intercept −0.36–8.5, R2 0.98–0.75). ES parameters had high sensitivity (96%) and specificity (83%) for detecting >70% stenosis. Lower early stress than rest EF (>5%), higher early stress than rest EDV, and early SSS >8 emerged as significant predictors of new-onset cardiac events. ConclusionsEarly post-stress gated SPECT MIBI yields comparable perfusion and functional parameters as the standard post-stress protocol. ES parameters are useful for detecting the existing coronary disease and for predicting future cardiac events. ES protocol is recommended for improving patient compliance and efficiency of nuclear cardiology services.
A STUDY OF THE INCIDENCE OF PSEUDOMONAS AERUGINOSA FROM VARIOUS NATURAL SOURCES

The seeming ubiquity of Pseudomonas aerumtnosa ramses the question as to its normal habitat. This organism has been isolated from soil, animal feces, water, and many other sources. The aquatic and soil habitat of the pseudomonads as a group suggests water or soil as a possible habitat, and many species of Pseudomonas can be isolated from these sources. Some species are plant pathogens, and a few may be animal pathogens. Many standard texts list various sources for this organism, but there seems to be very little or no information about sources from which it can be isolated with sufficient consistency so that they can be considered, in part at least, the natural habitat of the organism. This raises the question as to whether the animal infections represent invasion of the body by organisms that naturally occur elsewhere with a nonparasitic mode of existence, or whether these infections result from invasion of the tissues by organisms that are usually parasitic in the intestinal tract or elsewhere in the body. The following investigation was made in order to determine those sources from which P. aeruginosa could be isolated with the greatest regularity and coincidentally to study some of the identifying characteristics of this microorganism.
Walking Beliefs in Women With Fibromyalgia: Clinical Profile and Impact on Walking Behavior

Although exercise is essential for the treatment of fibromyalgia, adherence is low. Walking, as a form of physical exercise, has significant advantages. The aim of this article is to describe, in 920 women with fibromyalgia, the prevalence of certain walking beliefs and analyze their effects both on the walking behavior itself and on the associated symptoms when patients walk according to a clinically recommended way. The results highlight the high prevalence of beliefs related to pain and fatigue as walking-inhibitors. In the whole sample, beliefs are associated with an increased perception that comorbidity prevents walking, and with higher levels of pain and fatigue. In patients who walk regularly, beliefs are only associated with the perception that comorbidity prevents them from walking. It is necessary to promote walking according to the established way (including breaks to prevent fatigue) and to implement interventions on the most prevalent beliefs that inhibit walking.
Combining explicit and implicit measures of racial discrimination in health research.

OBJECTIVES To improve measurement of discrimination for health research, we sought to address the concern that explicit self-reports of racial discrimination may not capture unconscious cognition. METHODS We used 2 assessment tools in our Web-based study: a new application of the Implicit Association Test, a computer-based reaction-time test that measures the strength of association between an individual's self or group and being a victim or perpetrator of racial discrimination, and a validated explicit self-report measure of racial discrimination. RESULTS Among the 442 US-born non-Hispanic Black participants, the explicit and implicit measures, as hypothesized, were weakly correlated and tended to be independently associated with risk of hypertension among persons with less than a college degree. Adjustments for both measures eliminated the significantly greater risk for Blacks than for Whites (odds ratio = 1.4), reducing it to 1.1 (95% confidence interval = 0.7, 1.7). CONCLUSIONS Our results suggest that the scientific rigor of research on racism and health will be improved by investigating how both unconscious and conscious mental awareness of having experienced discrimination matter for somatic and mental health.
High-Performance and Stable Transparent Hf–In–Zn–O Thin-Film Transistors With a Double-Etch-Stopper Layer

Transparent hafnium indium zinc oxide thin-film transistors adopting single- and double-etch-stopper layers were evaluated. Compared to devices with a single SiOx etch stopper (ES) grown at 150°C, a double ES with a second SiOx film grown at 350°C provides a superior device performance such as improved subthreshold swing, threshold voltage, field effect mobility, and higher stability under a negative bias stress. The stretched-exponential analyses of the bias stress results indicate that the denser high-temperature SiOx protects more effectively the underlying semiconductor during the source/drain etch process and suppresses the generation of defect states therein.
Bacterial and fungal biofilm formation on contact lenses and their susceptibility to lens care solutions

Background: Microbial biofilm formation on contact lenses and lens storage cases may be a risk factor for contact lens-associated corneal infections. Various types of contact lens care solutions are used to reduce microbial growths on lenses. Objectives: The present study aimed at comparing the growths of biofilms on the different contact lenses and lens cases. The study also aimed at determining the effect of lens care solutions and bacteriophage on these biofilms. Materials and Methods: One type of hard lens and two types of soft lenses were used for the study. The organisms used were Staphylococcus aureus ATCC 25923, Pseudomonas aeruginosa ATCC 27853, Candida albicans ATCC 60193 and Escherichia coli ATCC 25922. Biofilm production was performed by modified O'Toole and Kolter method and effect of lens cleaning solutions and a crude coliphage on biofilms was also studied. Results were visualised using scanning electron microscopy and quantitated by colony counting method and spectrophotometric measurement of optical density (OD). Statistical analysis was done by SPSS 11.5, Kruskal–Wallis test and Chi-square test. Results: Soft lens cleaning solutions had a significant inhibitory effect (P = 0.020) on biofilm formation on soft lenses and also lens cases (P < 0.001). Soft lens cleaning solution 2 was more efficient than solution 1. However, no such inhibitory effect was observed with regard to hard lens cleaning solution, but for a significant reduction in the OD values (P < 0.001). There was no significant inhibitory effect by bacteriophages. Conclusion: This study showed the importance of selecting the appropriate lens cleaning solution to prevent biofilm production on contact lenses.
Social Bonds in the Epidemiology of Neurosis: A Preliminary Communication

Summary In a random sample of the general population (N = 142) a strong inverse relationship was found between social bonds and the presence of neurotic symptoms. This association was strongest in the case of close affectional ties. Together, measures of social bonds accounted for 47 per cent of the variance in neurotic symptoms. While there is likely to be contamination between the two sets of variables, and while the data do not indicate the direction of causality, these findings constitute an aetiological lead which should be pursued.
Neonatal thrombosis: report of a prospective Canadian and international registry.

OBJECTIVE We sought to obtain representative data on the risk factors, diagnosis, current management, and short-term outcome of neonatal thrombosis. RESEARCH DESIGN A case registry was established at McMaster University. Standardized questionnaires were mailed to collaborators at participating centers every 4 to 6 months. SETTING Eighty-five level III and modified level II neonatal units in North America, Europe, and Australia were invited to join the registry. PATIENTS Eligible infants were born between January 1990 and June 1993. Large-vessel thrombosis was diagnosed during the first month of life or up to 44 weeks post-conception after premature birth. The clinical impression of thrombotic vessel obstruction was confirmed using at least one imaging technique. RESULTS Physicians in 64 centers expressed their willingness to participate. A total of 97 cases (excluding stroke) were registered from 29 centers. Spontaneous renal venous thrombosis (n = 21) was diagnosed at a median age of 2 days. The other venous (n = 39), arterial (n = 33), and mixed (n = 4) thromboses presented later; 89% of them were associated with an intravascular catheter and 29% with systemic infection. Doppler ultrasonography was the definitive diagnostic test in 68% of cases; contrast angiography was performed infrequently (14%). A third of all patients (but 62% of infants with renal venous thrombosis) received supportive therapy only. Thrombolytic agents were prescribed for 28% of catheter-associated venous thromboses and 30% of all arterial thromboses. The remainder of the patients were given heparin. Most patients (82%) survived to hospital discharge. Mortality rates were highest among infants with aortic thrombosis or central venous line-associated thrombosis affecting the right atrium or the superior vena cava (33%). CONCLUSIONS Neonatal thrombosis is diagnosed fairly rarely. With the exception of spontaneous renal venous thrombosis, almost all cases are associated with indwelling catheters. Doppler ultrasound techniques are the most popular means of confirming the diagnosis in virtually all centers. Treatment varies greatly among different centers, probably because of the lack of scientific evidence about the optimum management of affected infants.
Performance rating scale for peer and self assessment 1

A performance rating scale was developed and tested on a class of junior medical students who rated themselves and four to ten of their peers. When 928 ratings were factor analysed, two strong factors, knowledge and relationship, emerged. Test-retest reliabilities were good. Validity was measured by correlation of ratings with grades, and though both sources of ratings correlated significantly with grades given by faculty, peer ratings were more highly related to grades than were self ratings. Students tended to rate themselves lower than they were rated by their peers. Grades are probably not the best estimate of performance, but are currently one of the most reliable. Use of the scale to judge performance of physicians in practice has not been tested. The question of how such evaluation of peer and self would relate to other measures of quality of care is raised.
Towards a digital economy with Chinese characteristics?

There are two opposing views when considering economic development strategies in the digital age: some insist that the ‘new economy’ applies mainly to the industrialized countries and are doubtful that new information and communications technologies (ICTs) will allow developing countries to leapfrog to higher levels of development; others argue that ‘jump-starting’ development may not be as difficult as the pessimists think. Through a case study on China’s ‘twin-track strategy’ for economic development, which involves merging industrialization and informatization, this article aims to investigate whether developing countries are able to play a significant role in shaping the digital revolution and the global ‘new economy’. The evidence presented in this article suggests that China’s status as a poor and developing country has not prevented its government from making effective preparations to embrace the opportunities and challenges associated with new ICTs in ways that are compatible with indigenous socioeconomic factors.
A Proportional Hazards Regression Model for the Subdistribution with Covariates‐adjusted Censoring Weight for Competing Risks Data

With competing risks data, one often needs to assess the treatment and covariate effects on the cumulative incidence function. Fine and Gray proposed a proportional hazards regression model for the subdistribution of a competing risk with the assumption that the censoring distribution and the covariates are independent. Covariate‐dependent censoring sometimes occurs in medical studies. In this paper, we study the proportional hazards regression model for the subdistribution of a competing risk with proper adjustments for covariate‐dependent censoring. We consider a covariate‐adjusted weight function by fitting the Cox model for the censoring distribution and using the predictive probability for each individual. Our simulation study shows that the covariate‐adjusted weight estimator is basically unbiased when the censoring time depends on the covariates, and the covariate‐adjusted weight approach works well for the variance estimator as well. We illustrate our methods with bone marrow transplant data from the Center for International Blood and Marrow Transplant Research. Here, cancer relapse and death in complete remission are two competing risks.
Effects of high intensity laser therapy on pain and function of patients with chronic back pain

[Purpose] This study examined the effects of High Intensity Laser Therapy on pain and function of patients with chronic back pain. [Subjects and Methods] This study evenly divided a total of 20 patients with chronic back pain into a conservative physical therapy group that received conservative physical therapy, and a high intensity laser therapy group that received High Intensity Laser Therapy after conservative physical therapy. All patients received the therapy three times a week for four weeks. For the high intensity laser therapy group, treatment was applied to the L1–L5 and S1 regions for 10 minutes by using a high intensity laser device while vertically maintaining the separation distance from handpiece to skin at approximately 1 cm. A visual analog scale was used to measure the pain and Oswestry Disability Index was used for functional evaluation. [Results] In a within-group comparison of the conservative physical therapy and high intensity laser therapy groups, both the visual analog scale and Oswestry Disability Index significantly decreased. In a between-group comparison after treatment, the high intensity laser therapy group showed a significantly lower visual analog scale and Oswestry Disability Index than the conservative physical therapy group. [Conclusion] High Intensity Laser Therapy can be an effective nonsurgical intervention method for reducing pain and helping the performance of daily routines of patients who have chronic back pain.
