RIGOR, RELEVANCE, AND RESEARCH PARADIGMS:A JOURNEY FROM PRACTITIONERTO NEOPHYTE RESEARCHER

A practitioner leaves behind the world of failed multi-million-dollar information systems projects to seek solutions in academe. Along the journey from IS practitioner to IS researcher, the author encounters two fundamental tensions regarding the conduct of social science. The first tension concerns the challenge of conducting research meeting the criteria of scientific rigor while addressing issues relevant to practitioners. The second tension centers on the debate concerning the suitability of positivist and non-positivist approaches to research in the social sciences. A review of the literature discussing these tensions led the author to the insight that the two tensions could be related and to the adoption of a multi-paradigmatic research framework as a means of reconciling the tensions. The essay takes the reader from genesis (the author’s motivation for conducting practitioner-oriented research), through exodus (the intellectual journey made through the literature to acquire tools of the social science field ), to revelation (discovery of the advantages of multiparadigmatic research in the IS field).

THE ROLE OF MARKET ORIENTATION AND LEARNING ORGANIZATION IN ACHIEVING HIGH INNOVATIVENESS AND BUSINESS PERFORMANCE IN INDONESIAN BATIK INDUSTRY

This study aims to examine the effects of market orientation and learning organization on firm innovativeness and business performance. This study follows a survey method to collect data pertaining to the phenomena of variables being investigated by utilizing a single respondent design. A total of 224 Indonesian batik companies are taken to test the proposed model by utilizing covariance-based structural equations modeling approach. It was found that both market orientation and learning organization was positively associated with firm innovativeness and business performance as well. In addition, firm innovativeness may account for the effects of market orientation and learning organization on business performance. This implies that the batik companies have to reorient their marketing strategy, including foster their market orientation. The batik companies also need to possess some degree of organizational learning in respond to the uncertain environment and market changes. In addition, the batik companies should put a greater emphasize to use market orientation and organizational learning benefits to generate innovation capability to achieve a high business performance.
Determination of tropical cirrus properties by simultaneous LIDAR and radiosonde measurements

High‐altitude tropical cirrus (TC) have been observed by lidar during a cruise of the German research vessel ‘Polarstern’ above the Atlantic between 8°S and 12°. The backscatter lidar data give a detailed picture of the vertical structure of the clouds with a high time resolution. Using the data of radiosondes, which were launched twice a day aboard ‘Polarstern,’ the temperature of the clouds as well as the structure of the tropical tropopause is characterized. The clouds are found in an altitude between 14 km and 17 km, with a mean optical depth of τ = 0.02 and a mean temperature of 198 K. Tropical Cirrus appear in two distinct layers which are separated by a change in wind direction. This structure was observed south as well as north of the ITCZ. Cloud tops are often found at the thermal tropopause, in some case these clouds are of the ultra‐thin type.
On CAD/CAM generated fixed dental prostheses, fit and effect of ceramic veneering

The general aims of this thesis were to study CAD/CAM production processes, material aspects on cobalt-chromium (CoCr), clinical performance, and fit of tooth-, and implant-supported fixed dental prostheses (FDPs). A retrospective study of ceramic veneered CoCr FDPs was conducted to evaluate the performance of restorations made with the lost wax technique. One hundred forty-nine patients with 201 FDPs were followed for five years by data collection from patient records. To study CAD/CAM techniques, the fit of tooth-supported CNC-milled CoCr three-unit FDPs, made using conventional or digital impression techniques, was compared. Also, the fit of implant-supported CNC-milled and additively manufactured CoCr and titanium FDPs was evaluated before and after ceramic veneering. CoCr FDPs are a promising alternative to other dental alloys, presenting a low level of ceramic fractures, cement failure, caries, and other complications during the first five years in function. To evaluate their longer-term success and possible biologic adverse effects, further long-term randomized controlled studies are necessary. The digital impression technique produced FDPs with a significantly more accurate fit than conventional impressions using VPS impression material. Implant-supported frameworks can be produced in either titanium or CoCr using either CNC-milling or additive manufacturing with a fit well within the range of what is regarded as clinically acceptable. The fit of frameworks of both materials and production techniques are affected by the ceramic veneering procedure to a small extent, most likely of no clinical significance.
Data report: microbial diversity in sediment near Grizzly Bare Seamount in Holes U1363B and U1363G 1

Microorganisms inhabiting sediment in close proximity to recharging basement outcrops are of interest because of the enhanced advective fluid flow in these locations, which is expected to exert unique selective pressures on the resident microbial communities. Here, Integrated Ocean Drilling Program (IODP) boreholes were used to access sediment microbial communities near Grizzly Bare recharge seamount on the Juan de Fuca Ridge eastern flank. The two locations examined in this study, Holes U1363G and U1363B, are 50 and 177 m away from the center of the outcrop, respectively. In general, small subunit ribosomal RNA gene clones from all three domains of life were detected; these groups were predominantly related to microorganisms known to reside in marine sediment. A large fraction of environmental gene clones recovered from Hole U1363B and U1363G sediment were related to uncultivated, candidate phyla of Bacteria such as BHI80-139, BRC1, JS1, OPB41, and TA06. Hole U1363B and U1363G sediment clone libraries were generally dominated by the domain Bacteria and particularly the phylum Chloroflexi, which comprised approximately one-quarter of the total gene clones identified. However, borehole sediment also contained several archaeal lineages that were phylogenetically affiliated with the Miscellanenous Crenarchaeotal Group. Eukaryotic fungi were only detected within the interstitial water sample from Hole U1363B. Finally, a minor portion of clones recovered from sediment in this study were also recovered from basement fluid samples previously characterized from Baby Bare discharge seamount and Ocean Drilling Program and IODP borehole Circulation Obviation Retrofit Kit Observatories (CORKs) in Holes 1026B and U1301A, which are ~50 km to the north-northeast.
Enhancing Women’s Well-Being: The Role of Psychological Capital and Perceived Gender Equity, With Social Support as a Moderator and Commitment as a Mediator

The study aims to determine the role of psychological capital and perceived gender equity on employee well-being, particularly women, and assess if commitment mediates and social support moderates the relationships between psychological capital, perceived gender equity, and well-being. A personal survey method was employed for data collection using standardized measures from a representative sample of 433 managers (201 women and 233 men) from private sector companies in India. The findings revealed that perceived gender equity in the workplace positively impacts employee well-being for both men and women, with the greater impact being on women’s well-being. To Facilitate employee well-being, organizations can leverage the strengths of psychological capital through training interventions and can promote perceived gender equity through appropriate policies and practices. This bridges the knowledge gap in developing and utilizing psychological capital to enhance employee well-being, especially for women, who are under pressure due to their demanding multiple roles at work and home.
Stock Prices and Consumption: Sub-Sahara African Experience

This paper investigates the effect of stock market variables on consumption growth in 12 selected sub-Saharan African countries within the period 1988–2012 using dynamic panel estimation techniques. Specifically, we examine if consumption growth is in any way being influenced by stock returns and dividend yield. While the use of returns determines the existence of a wealth, dividend yield shows how consumption is affected by short-term disequilibrium of prices from fundamental value. Having critically examined the econometric properties of our data, the results from dynamic panel estimation support a significant direct relationship between stock price (returns) and consumption growth which implies the existence of wealth effect. Similarly, the results indicate insignificant positive relationship between the dividend yield and consumption growth which implies that bubbles in the market can increase consumption but with fear of future bust. Overall, we argue that consumption growth can be influenced by stock price (returns), thus policy-maker in the sub-region can leverage on this link to stimulate economic growth.
An Accurate and Computationally Efficient Explicit Friction Factor Model

The implicit Colebrook equation has been the standard for estimating pipe friction factor in a fully developed turbulent regime. Several alternative explicit models to the Colebrook equation have been proposed. To date, most of the accurate explicit models have been those with three logarithmic functions, but they require more computational time than the Colebrook equation. In this study, a new explicit non-linear regression model which has only two logarithmic functions is developed. The new model, when compared with the existing extremely accurate models, gives rise to the least average and maximum relative errors of 0.0025% and 0.0664%, respectively. Moreover, it requires far less computational time than the Colebrook equation. It is therefore concluded that the new explicit model provides a good trade-off between accuracy and relative computational efficiency for pipe friction factor estimation in the fully developed turbulent flow regime.
Entrepreneurial Knowledge and Aspirations of Dentistry Students in South Africa

An investigation of the intentions and knowledge of entrepreneurship of final-year university dentistry students is reported, with particular regard to the factors of gender and race. A questionnaire survey was used with final-year dentistry students, over two years, at the University of the Western Cape in South Africa. The findings show that dentistry students across race and gender groups believed that entrepreneurship education was important. At least half of the students showed an interest in starting a business practice soon after their graduation and completion of a mandatory one-year internship, with more male students indicating an interest in starting a business than female students. More Black African students indicated interest compared to other race groups (Coloureds, Whites and Indians). There were no significant differences between male and female students with regard to knowledge of entrepreneurship, but there were significant differences with regard to race in the scores for knowledge of entrepreneurship, with White students scoring the highest and African students the lowest. The authors conclude that entrepreneurship education should be included in the curriculum in the final year of dentistry studies to encourage business practice start-up soon after the one-year internship period, with the aim of contributing to growth in employment.
Optimization Of Blasting Design Parameters On Open Pit Bench A Case Study Of Nchanga Open Pits

In hard rock mining, blasting is the most productive excavation technique applied to fragment insitu rock to the required size for efficient loading and crushing. In order to blast the insitu rock to the desired fragment size, blast design parameter such as bench height, hole diameter, spacing, burden, hole length, bottom charge, specific charge and rock factor are considered. The research was carried out as a practical method on Nchanga Open Pits (NOP) ore Bench to optimize the blasting design parameters that can yield the required fragmentation size thereby reducing the shovel loading times and maximizing efficiency of the subsequent mining unit operations such as hauling and crushing. Fragmentation characteristics such as the mean fragment size were measured by means of a digital measuring tape and predicated using the Kuznetsov equation and rock factor value of ore bench was calculated using Lilly, (1986) equations by means of rock characteristics. Traditional blasting design parameters were acquired for NOP and modified using Langerfors and Sharma, P.A approaches. Several blast operations were conducted using both traditional and modified blasting design parameters on the same ore bench with the same geological conditions. Loading times of the shovel and fragment sizes were obtained after the blasts from ore bench where both the traditional and modified blasting design parameters were applied. Results show that mean fragment size and loading times were reduced from 51cm and 12minutes to 22cm and 3minutes where traditional and modified blasting design parameters were applied respectively.
Comparison of Diverse Ensemble Neural Network for Large Data Classification

In a large dataset classification, a higher number of attributes commonly evolve over time, where many dynamic learning strategies have been proposed such as the ensemble network and incremental neural network. Ensemble network is a learning paradigm where many neural networks are jointly used to solve a problem. The relationship between the ensemble and component of neural networks is analyzed from the context of classification in integrated framework. This task would reveal that, it may be better to have many neural networks instead the incremental neural network. Most approaches of ensemble using totally different classifiers for prediction. Then, in order to find an appropriate neural network from ensemble members, it can be selected from a set of different available neural networks. Thus, a Distributed Reordering Technique (DRT) is proposed. DRT is an enhanced algorithm based on distributed random for different neural networks. The weights are randomly assigned to networks in order to evolve, so that they can characterize each neural network to some extent of fitness in constituting a better result. The ensemble network integrated framework supported by the selection of some neural networks based on output and weights that made up the ensemble. The experimental study shows that in comparing with some ensemble approaches such as Bagging, DRT can generate a neural network with enhanced performance and stronger generalization ability. Furthermore, the use of DRT for neural network classifier is practical and relevance to classification systems for large and can be applied to different large data dimension in future.
ANTIBACTERIAL ACTIVITY OF EXTRACTS FROM SALVIA OFFICINALIS AND ROSMARINUS OFFICINALIS OBTAINED BY SONICATION AND MACERATION METHODS

Objective: Our study attempts to compare the phenolic contents and the antibacterial activity of the methanol extracts obtained by sonication and classical maceration from Rosmarinus officinalis and Salvia officinalis. Methods: The extracts were obtained from two plants belonging to Lamiaceae family; S. officinalis and R. officinalis. These plants were collected at February 2011 in the National Institute of Medicinal and Aromatic Plants (Morocco). The total phenolic content was evaluated using Folin Ciocalteu reagent. Furthermore, the antibacterial effect of the extract was tested against eight bacterial strains using the disk-diffusion method. Results: Our results show that sonication was more effective for the extraction of phenolic compounds than the classical maceration. Moreover, all extracts showed antibacterial activity against Gram-positive bacteria tested (Bacillus subtilis and Staphylococcus aureus). Gram-negative bacteria (Pseudomonas aeruginosa and Escherichia coli) were found to be resistant.
Association of Health Literacy Levels Between Family Members

Background: Health literacy (HL) is not solely an individual skill but a distributed resource available within individual's social networks. This study explored the associations between individual and family member HL using two separate self-report measures of HL: the European Health Literacy Survey Questionnaire (HLS-EU-Q47) and the Communicative and Critical Health Literacy scale (CCHL). Methods: A self-administered questionnaire survey was conducted with 501 pairs of Japanese residents aged 30 to 79 and their family members whom they most often consulted for help with health issues. HL was measured using HLS-EU-Q47 and CCHL. Results: The HL scores of individuals and their family members were positively correlated for both measures. The correlation was stronger for the HLS-EU-Q47, presumably because it measures the perceived manageability of health-related tasks that implicitly depend on the availability of support for an individual. In contrast, the CCHL measures a single individual's perceived abilities. Both individual and family member CCHL scores were independently related to individual HLS-EU-Q47 scores, particularly when an individual had a family member with a higher CCHL score than his/her own. Conclusions: Limited individual ability to achieve health-related tasks might be compensated for by the higher ability of other family members. In addressing problems with limited health literacy, future studies should focus not only on the individual but also on people who can provide an individual with support.
What's ontology got to do with it? On nature and knowledge in a political ecology of the 'green economy'

Abstract Contemporary market-based (i.e. neoliberal) 'green economy' approaches to environmental degradation emphasise exchanges whereby quantified units of environmental harm are traded or 'offset' for compensating units of environmental health. Also encouraged is a view that economic growth can be 'greened' through 'decoupling' economic value from material ecological realities. Such approaches tend to frame biophysical natures in terms of aggregates, such as an 'aggregate natural capital rule' and 'net zero carbon. ' Naturesbeyond-the-human are thereby understood and enacted as calculable, exchangeable, substitutable and commensurable between different spatial and temporal sites, making up an 'aggregate' or 'net' value overall. This article uses a comparative cross-cultural engagement to problematize ontological assumptions regarding the nature of nature underscoring the rationality of these aggregating and offsetting 'solutions. ' Drawing on literatures from environmental anthropology and environmental ethics, combined with ethnographic material from long-term field research in north-west Namibia, the article considers elements of alternative cultural ontologies and the ways these may give rise to a different array of practices with value for conceiving and generating 'sustainability. ' It adheres to a critical political ecology perspective in understanding the ways that power structures the ontologies that become both privileged and occluded in neoliberal strategies for green economy governance. In doing so, the article argues that sensitivity to the ontological politics through which spaces and entities are defined and known and which thereby shape environmental conflicts, may be key to recognising with more depth the sometimes significantly different 'natures' being struggled over in such conflicts. Key words: ontology; green economy; offsetting; decoupling; sustainability; value; natures-beyond-thehuman; neoliberalism; political ecology
