This paper presents a quantitative study in measuring the perception of Malaysian SME towards ecommerce as an innovation and factors affecting the adoption of it. It is concerned with initiatives that are intended to help SME in Malaysia to adopt E-commerce as an innovation. The research has two main emphases: First, it presents some preliminary findings on the perception of Malaysian SME towards E-commerce as an innovation; and the level of confidence towards E-commerce as an innovation. Second, it streamlines various initiatives by Ministry of International Trade and Industry (MITI), Small and Medium Industries Development Corporation (SMIDEC), BankNegara Malaysia and local governments in accelerating the acceptance of E-commerce by Malaysian SME. The study engaged 38 SME participants through a survey using a self-administered questionnaire. 32% of the surveyed SME are from the Type 1 Industry; comprising manufacturing, manufacturing related services, and agro-based services and about 68% are from Type 2 Industry comprising services, primary agriculture, and ICT. The self administered questionnaire consists of two sections. Section I contains demographic information and SME specification while Section II contains 37 items: 31 items utilised Likert Scales items ranging from 1 (strongly disagree) to 5(strongly agree), and six items utilised defined interval scales. Rogers' attributes of innovations (2003): relative advantage, compatibility, complexity, trial ability and observability were used in the construct of the research instrument. This research emphasizes on Rogers'framework, as it was found useful where the study sought to understand the diffusion and use of Ecommerce by Malaysian SME in the investigation. Descriptive statistics were used to analyse and present empirical data of the 38 SME. The results from the quantitative data provided information on addressing barriers to SME, and confirmed the characteristics of Rogers' adoption categories. The study shows that the instrument which was designed with seven constructs lacked internal consistency in two determinants: relative advantage and observability. Findings interpreted through Rogers' theory suggest that an action plan should include initiatives to help SME towards E-commerce as an innovation.

<P>Aims: To examine if pentraxin can help identify patients benefitting most from primary Percutaneous Coronary Intervention (PCI) vs. fibrinolysis. </P><P> Methods: Patients with acute ST-Elevation Myocardial Infarction (STEMI) were consecutively recruited from a community center without PCI and a tertiary center with PCI facilities. Left ventricular ejection fraction (LVEF) was determined echocardiographically at baseline and 5 days after the index admission; the difference between two measurements was considered as the magnitude of improvement. We used regression models to test the hypothesis that the magnitude of the advantage of PCI over fibrinolysis in preserving LVEF 5 days after STEMI is modified by pentraxin 3 (PTX3). </P><P> Results: The functional advantage (LVEF) of the PCI over fibrinolysis has been determined by PTX3. LVEF was attenuated and even reversed as PTX3 level increased. The primary PCI of the participants with less than 7 ng.ml-1 PTX3 level, achieved a clinically significant increase in the LVEF as compared to fibrinolysis. At lower levels of PTX3, PCI shows a conspicuous advantage over fibrinolysis in terms of the probability of developing an LVEF <40%. </P><P> Conclusion: We demonstrated not only the functional advantage of PCI over fibrinolysis performed within the recommended time frames but also the relative advantage of its relevance to the baseline PTX3 levels. PTX3 can play a role in determining the choice of best therapy. More than 75% of patients with STEMI who have PTX3 levels ≤7 ng.ml-1 imply the need of PCI.</P>

E-learning is a method of delivering knowledge using information technology and electronic media for the remote users. The advantages of e-learning method can be fully achieved with the postgraduate studies as majority of the postgraduate students are engaged in learning while they are working and also geographically dispersed due to the family and work life thus physically appearing for the lecture sessions are difficult to them. This paper attempts to develop a framework to measure the postgraduate students’ perceived technology acceptance by developing a modified version of the Technology Acceptance Model (TAM) which replaces perceived usefulness and perceived ease of use in the original model of TAM with relative advantage and complexity and incorporate other variables of trialability, observability, compatibility, psychological wellbeing and social influence of the students. The developed model is validated using 30 postgraduate students from Sri Lanka and thus this model can be used in future researchers to measure the perceived e-learning acceptance of postgraduate students.

Women who attain more education tend to have children with more educational opportunities, a transmission of educational advantages across generations that is embedded in the larger structures of families’ societies. Investigating such country-level variation with a life-course model, this study estimated associations of mothers’ educational attainment with their young children’s enrollment in early childhood education and engagement in cognitively stimulating activities in a pooled sample of 36,400 children ( n = 17,900 girls, 18,500 boys) drawn from nationally representative data sets from Australia, Ireland, U.K., and U.S. Results showed that having a mother with a college degree generally differentiated young children on these two outcomes more in the U.S., potentially reflecting processes related to strong relative advantage (i.e., maternal education matters more in populations with lower rates of women’s educational attainment) and weak contingent protection (i.e., it matters more in societies with less policy investment in families).

Background: Despite their inclusion in Rogers’ seminal diffusion of innovations theory, few implementation studies empirically evaluate the role of intervention characteristics. Now, with growing evidence on the role of adaptation in implementation, high-quality measures of characteristics such as adaptability, trialability, and complexity are needed. Only two systematic reviews of implementation measures captured those related to the intervention or innovation and their assessment of psychometric properties was limited. This manuscript reports on the results of eight systematic reviews of measures of intervention characteristics with nuanced data regarding a broad range of psychometric properties. Methods: The systematic review proceeded in three phases. Phase I, data collection, involved search string generation, title and abstract screening, full text review, construct assignment, and citation searches. Phase II, data extraction, involved coding psychometric information. Phase III, data analysis, involved two trained specialists independently rating each measure using PAPERS (Psychometric And Pragmatic Evidence Rating Scales). Results: Searches identified 16 measures or scales: zero for intervention source, one for evidence strength and quality, nine for relative advantage, five for adaptability, six for trialability, nine for complexity, and two for design quality and packaging. Information about internal consistency and norms was available for most measures, whereas information about other psychometric properties was most often not available. Ratings for psychometric properties fell in the range of “poor” to “good.” Conclusion: The results of this review confirm that few implementation scholars are examining the role of intervention characteristics in behavioral health studies. Significant work is needed to both develop new measures (e.g., for intervention source) and build psychometric evidence for existing measures in this forgotten domain. Plain Language Summary Intervention characteristics have long been perceived as critical factors that directly influence the rate of adopting an innovation. It remains unclear the extent to which intervention characteristics including relative advantage, complexity, trialability, intervention source, design quality and packaging, evidence strength and quality, adaptability, and cost impact implementation of evidence-based practices in behavioral health settings. To unpack the differential influence of these factors, high quality measures are needed. Systematic reviews can identify measures and synthesize the data regarding their quality to identify gaps in the field and inform measure development and testing efforts. Two previous reviews identified measures of intervention characteristics, but they did not provide information about the extent of the existing evidence nor did they evaluate the host of evidence available for identified measures. This manuscript summarizes the results of nine systematic reviews (i.e., one for each of the factors listed above) for which 16 unique measures or scales were identified. The nuanced findings will help direct measure development work in this forgotten domain.

Abstract Background Neurorehabilitation engineering faces numerous challenges to translating new technologies, but it is unclear which of these challenges are most limiting. Our aim is to improve understanding of rehabilitation therapists’ real-time decision-making processes on the use of rehabilitation technology (RT) in clinical treatment. Methods We used a phenomenological qualitative approach, in which three OTs and two PTs employed at a major, technology-encouraging rehabilitation hospital wrote vignettes from a written prompt describing their RT use decisions during treatment sessions with nine patients (4 with stroke, 2 traumatic brain injury, 1 spinal cord injury, 1 with multiple sclerosis). We then coded the vignettes using deductive qualitative analysis from 17 constructs derived from the RT literature and the Consolidated Framework for Implementation Research (CFIR). Data were synthesized using summative content analysis. Results Of the constructs recorded, the five most prominent are from CFIR determinants of: (i) relative advantage, (ii) personal attributes of the patients, (iii) clinician knowledge and beliefs of the device/intervention, (iv) complexity of the devices including time and setup, and (v) organizational readiness to implement. Therapists characterized candidate RT as having a relative disadvantage compared to conventional treatment due to lack of relevance to functional training. RT design also often failed to consider the multi-faceted personal attributes of the patients, including diagnoses, goals, and physical and cognitive limitations. Clinicians’ comfort with RT was increased by their previous training but was decreased by the perceived complexity of RT. Finally, therapists have limited time to gather, setup, and use RT. Conclusions Despite decades of design work aimed at creating clinically useful RT, many lack compatibility with clinical translation needs in inpatient neurologic rehabilitation. New RT continue to impede the immediacy, versatility, and functionality of hands-on therapy mediated treatment with simple everyday objects.

Abstract Older adults with a chronic health condition (e.g. hypertension) use various self-management methods. Healthcare technologies have the potential to support health self-management. However, it is necessary to understand the acceptance of these technologies as a precursor to older adults’ adoption and integration into their health plan. Our focus was on the factors older adults with hypertension initially consider when introduced to three new healthcare technologies that might support their health self-management. We compared their considerations for a blood pressure monitor, an electronic pillbox and a multifunction robot to simulate incrementally more complex technologies. Twenty-three participants (aged 65–84) completed four questionnaires and a semi-structured interview. The interview transcripts were analysed using a thematic analysis approach. We identified the factors that were frequently mentioned among the participants for each of the three healthcare technologies. The factors that older adults initially considered were familiarity, perceived benefits, perceived ease of use, perceived need for oneself, relative advantage, complexity and perceived need for others. Upon further reflection, participants considered advice acceptance, compatibility, convenience, facilitating conditions, perceived usefulness, privacy, subjective norm, and trust. We integrated the factors that older adults considered into the Healthcare Technology Acceptance Model (H-TAM), which elucidates the complexity of healthcare technology acceptance and provides guidance for future explorations.

AbstractMost animal species have a complex life cycle (CLC) with metamorphosis. It is thus of interest to examine possible benefits of such life histories. The prevailing view is that CLC represents an adaptation for genetic decoupling of juvenile and adult traits, thereby allowing life stages to respond independently to different selective forces. Here I propose an additional potential advantage of CLCs that is, decreased variance in population growth rate due to habitat separation of life stages. Habitat separation of pre- and post-metamorphic stages means that the stages will experience different regimes of environmental variability. This is in contrast to species with simple life cycles (SLC) whose life stages often occupy one and the same habitat. The correlation in the fluctuations of the vital rates of life stages is therefore likely to be weaker in complex than in simple life cycles. By a theoretical framework using an analytical approach, I have (1) derived the relative advantage, in terms of long-run growth rate, of CLC over SLC phenotypes for a broad spectrum of life histories, and (2) explored which life histories that benefit most by a CLC, that is avoid correlation in vital rates between life stages. The direction and magnitude of gain depended on life history type and fluctuating vital rate. One implication of our study is that species with CLCs should, on average, be more robust to increased environmental variability caused by global warming than species with SLCs.
