Fundamental view of the outcomes of entrepreneurship education
No full text
The research
paper presents a holistic framework of the outcomes of entrepreneurship
education (EE) at educational and socio-economic levels. Employing the general
scientific research methods, monograph and logical construction, the author investigates
the fundamental origins of the European Competence Framework for
entrepreneurial learning and identifies a scientific justification for its
implementation. This work is also the first to exploit an integral view of
entrepreneurship as a combination of employability, intrapreneurship and
venture creation – for measuring the impact of entrepreneurship education, and
to set linkages between learning outcomes in real life and educational settings.
The target audiences for this paper include entrepreneurship educators,
researchers and EE decision-makers. </p

Java EE and Spring Platform Comparison in Web Application Development
No full textJava EE un Spring ir populārākās Java tīmekļa lietotņu izstrādes platformas. Vēsturiski Java EE platformas sākotnējās versijas sarežģītā izstrādes procesa un resursu patēriņa dēļ izstrādātāju vidū iemantoja "smagsvara" platformas slavu. Kā alternatīva "vieglā svara" platforma tika radīta Spring platforma. Laika gaitā Java EE tika uzlabota, un platformas jaunākajās versijās izstrādes procesa sarežģītība ir mazinājusies.
Darbā tiek apskatītas Java EE 6 un Spring 3 platformu piedāvātās iespējas un analizēta to funkcionalitāte. Izmantojot autora izstrādātas lietotnes, tiek testēta un analizēta platformu veiktspēja. Noslēgumā tiek doti ieteikumi platformas izvēlē atkarībā no realizējamā projekta specifikas.Java EE and Spring are most popular Java web application platforms. Early versions of Java EE platform had complicated development process and high resource usage so in developer community it was called "heavy-weight". Spring platform emerged as an alternative "light-weight" platform. Later Java EE was updated and development complexity was decreased.
Paper describes features of Java EE 6 and Spring 3 platform and analyses platform functionality. Performance of both platforms is tested using applications developed by author. In conclusion author gives recommendations for platform choice depending on project characteristics
Development and characterization of organic solvent resistant membrane cascades for the single solvent fractionation and isolation of the active molecules from natural products: Application to kawa kawa (Macropiper excelsum)
No full textFull text is available to authenticated members of The University of Auckland only.Although natural products are being used in many pharmaceutical and food industries, a large majority of compounds that are available at present have not been tested. The major problem is the lack of techniques that can be used for the economical extraction and separation of compounds present in them. Conventional techniques being used in processes consume considerable energy and materials in the form of evaporation and solvent exchange and can often therefore both costly and environmentally unfriendly. However, membrane separation technology has a great potential to be used for separation, fractionation and isolation of the active molecules from natural products avoiding high temperatures and excessive solvents. Consequently, the aim of this project was to develop a membrane separation technique for the isolation of compounds present in natural products. Macropiper excelsum (kawa kawa), a plant found in New Zealand, was selected as the model natural product for this purpose, due to its potential medicinal and insecticidal applications. The compounds present in it include: demethoxyexcelsin, diayangambin for their anti HIV properties and for the treatment of immune and inflammatory responses, excelsin and juvadecene for their insecticidal behaviour, and myristicin - which is present in the largest quantity - for its medicinal and insecticidal properties. Experiments were performed initially with the aim to find the effects of different parameters on the extraction. Myristicin being present in largest quantity was selected for this purpose. The effect of two extraction techniques (using a Buchi B-811 soxhlet type extractor and a continuous stirred tank extractor) with three different solvents (methanol, ethanol and acetone) on the extraction of the compounds present in macropiper excelsum was determined. Extracted solutions were then fractionated, using the extract solvent, through a membrane cascade which utilised both old and new generation organic solvent resistant nanofiltration membranes (from the StarMem and DuraMem range). The resulting permeates and the original extract solutions were analysed by reverse phase HPLC using a new method developed specifically for the Macropiper excelsum extract solutes. It was found for myristicin that the extraction is higher in methanol solvents and the rate of extraction increases with temperature, amount of feed and when using the Buchi B- 811 apparatus. However, this result was not true for all the other compounds present in the extracts, namely diayangambin, epiexcelsin and some yet to identify compounds, where the amount extracted in the continuous stirred tank was higher than the Buchi B-811 extractor working at higher temperatures, indicating extraction must be tailored to the wanted compounds. The StarMem and DuraMem membranes were able to fractionate some of the compounds present. Two examples of compounds demethoxyexcelsin and myristicin were used to demonstrate the possibilities of such results. Using the rejection data for extractions in acetone with a Buchi B-811 extraction system, it was found that, demethoxyexcelsin can be purified by using one StarMem 122 and three DuraMemTM 200 membranes following in series. At the end a solution with concentration of 94% Demethoxyexcelsin with the yield of 13.4 percent was obtained. Overall it is concluded that the use of sharp MWCO membranes and the fabrication of membrane with MWCO between the available membranes will allow more compounds with a higher yield to be isolated from the macropiper excelsum (kawa kawa) than is currently possible with the StarMem and DuraMem membrane
Influential Publications in Ecological Economics: A Citation Analysis
No full textWe assessed the degree of influence of selected papers and books in ecological economics using citation analysis. We looked at both the internal influence of publications on the field of ecological economics and the external influence of those same publications on the broader academic community. We used four lists of papers and books for the analysis: (1) 92 papers nominated by the Ecological Economics (EE) Editorial Board; (2) 71 papers that were published in EE and that received 15 or more citations in all journals included in the Institute for Scientific Information (ISI) Citation Index; (3) 57 papers that had been cited in EE 15 or more times; and (4) 77 monographs and edited books that had been cited in EE 15 or more times. For each publication we counted the total number of ISI citations as well as the total number of citations in EE. We calculated the average number of citations/yr to each paper since its publication in both the ISI database and in EE, along with the percentage of the total ISI citations that were in EE. Ranking the degree of influence of the publications can be done in several ways, including using the number of ISI citations, the number of EE citations or both. We discuss both the internal and external influence of publications and show how these influences might be considered jointly. We display and analyze the results in several ways. By plotting the ISI citations against the EE citations we can identify those papers that are mainly influential in EE with some broader influence, those that are mainly influential in the broader literature but have also had influence on EE, and other patterns of influence. There are both overlaps and interesting lacunae among the four lists that give us a better picture of the real influence of publications in ecological economics versus perceptions of those publications' importance. By plotting the number of citations vs. date of publication, we can identify those publications that are projected to be most influential. Plots of the time series of citations over the 1990-2003 period show a generally increasing trend (contrary to what one would expect for an "average" paper) for the top papers. We suggest that this pattern of increasing citations (and thus influence) over time is one hallmark of a "foundational" paper.
Environmental, institutional, and demographic predictors of environmental literacy among middle school children.
No full textBuilding environmental literacy (EL) in children and adolescents is critical to meeting current and emerging environmental challenges worldwide. Although environmental education (EE) efforts have begun to address this need, empirical research holistically evaluating drivers of EL is critical. This study begins to fill this gap with an examination of school-wide EE programs among middle schools in North Carolina, including the use of published EE curricula and time outdoors while controlling for teacher education level and experience, student attributes (age, gender, and ethnicity), and school attributes (socio-economic status, student-teacher ratio, and locale). Our sample included an EE group selected from schools with registered school-wide EE programs, and a control group randomly selected from NC middle schools that were not registered as EE schools. Students were given an EL survey at the beginning and end of the spring 2012 semester. Use of published EE curricula, time outdoors, and having teachers with advanced degrees and mid-level teaching experience (between 3 and 5 years) were positively related with EL whereas minority status (Hispanic and black) was negatively related with EL. Results suggest that school-wide EE programs were not associated with improved EL, but the use of published EE curricula paired with time outdoors represents a strategy that may improve all key components of student EL. Further, investments in teacher development and efforts to maintain enthusiasm for EE among teachers with more than 5 years of experience may help to boost student EL levels. Middle school represents a pivotal time for influencing EL, as improvement was slower among older students. Differences in EL levels based on gender suggest boys and girls may possess complementary skills sets when approaching environmental issues. Our findings suggest ethnicity related disparities in EL levels may be mitigated by time spent in nature, especially among black and Hispanic students
Information portal for women's organization / Emmy Jong Ee Mei
No full textThis report describes the proposed Information Portal for Women's Organization developed for the PELITAWANIS TNB Organization, a women's organization established by Tenaga Nasional Berhad (TNB) to foster closer ties between the women work force and wives of the employees from all levels in TNB. The PELITAWANIS TNB Portal is for use by the members of the PELITAWANIS TNB Organization.This portal is a one-person project handled by the author. Therefore, the author is responsible for the development of all the system module. Among the modules are search facilities, online, registration, forum, bulletin board, member list and update, and user feedback. The purpose of this portal is to present information regarding the organization, its activities, members and services in an interesting manner and to make this information readily available to its members and other interested parties. It also facilitates information sharing besides encouraging interaction and communication between members. The portal also servesas an avenue for announcements regarding the organization. Other than that, it will also be possible to monitor the log ins of the members. The administrators of the portal can perform management tasks to update the contents of the portal and the member data. The Waterfall with Prototype model is chosen as the development platform is the Microsoft SharePoint Portal Server. The PELITAWANIS TNB portal of course will also undergo testing and evaluation after its completion. With the birth of the portal, its is hoped that this will encourage more women to use the facilities made available to enrich their knowledge and experience, particularly in the areas of information and communication technology
