Innovative and Sustainable Food Production and Food Consumption Entrepreneurship: A Conceptual Recipe for Delivering Development Success in South Africa

Innovative food production and food consumption entrepreneurship can be viewed as a recipe for delivering sustainable development goals to promote economic, human, and community growth among vulnerable and marginalised communities in South Africa (SA). This study critically analyses the trends and related issues perpetuating the development gap between privileged and marginalised communities in SA. It explores the link between innovative food production and food consumption entrepreneurship and underdevelopment based on sustainable development goals (SDGs). The study also generates a conceptual model designed to bridge the development gap between privileged and marginalised communities in SA. Philosophically, an interpretivism research paradigm based on the socialised interpretation of extant literature is pursued. Consistent with this stance, an inductive approach and qualitative methodological choices are applied using a combination of thematic analysis and grounded theory to generate research data. Grounded theory techniques determine the extent to which the literature review readings are simultaneously pursued, analysed, and conceptualised to generate the conceptual model. Research findings highlight the perpetual inequality in land distribution, economic and employability status, social mobility, gender equity, education, emancipation, empowerment, and quality of life between privileged and marginalised societies in SA. Underdevelopment issues such as poverty, unemployment, hunger, criminal activities, therefore, characterise marginalised communities and are linked to SDGs. Arguably, food production and food consumption entrepreneurship are ideally positioned to address underdevelopment by creating job opportunities, generating income, transforming the economic status, social mobility, and quality of life. Although such entrepreneurship development initiatives in SA are acknowledged, their impact remains insignificant because the interventions are traditionally prescriptive, fragmented, linear, and foreign-driven. A robust, contextualised, integrated, and transformative approach is developed based on the conceptual model designed to create a sustainable, innovative, and digital entrepreneurship development plan that will be executed to yield employment, generate income and address poverty, hunger, gender inequity. To bridge the gap between privileged and marginalised societies. The conceptual model will be used to bridge the perpetual development gap between privileged and marginalised societies. In SA is generated. Recommended future research directions include implementing, testing, and validating the model from a practical perspective through a specific project within selected marginalised communities.
Lapine CD133+CD34+ endothelial progenitor cells for musculoskeletal research in preclinical animal trials

BackgroundValidated animal models form the cornerstone of in vivo clinical trials. Rabbits, for instance, have been widely used in musculoskeletal research, but there is a lack of knowledge regarding endothelial progenitor cells (EPCs) obtained from their peripheral blood (PB). Further, there is an ambiguity regarding the origin of EPCs in blood. The present study aimed to isolate and compare rabbit EPCs with human EPCs and explore the origin of EPCs in PB. MethodsMononuclear cells (MNCs) were isolated from the PB of rabbits and humans by density centrifugation. Different parameters, such as seeding density, type of medium, and technique (Depletion v/s Hills technique) were standardized for the emergence of EPCs. Homogenous rEPCs and hEPCs were isolated by double sorting with fluorescence-activated cell sorting (FACS) using CD34CD133 or CD34VEGFR-2 antibody. Expanded CD34+CD133+ EPCs from both rabbits and humans were compared using growth curve, acetylated low-density lipoprotein (acLDL) uptake, lectin binding, flow cytometry, immunofluorescence (IF), tubulogenic assay, and NO production. ResultsInitial seeding density of MNCs at 1 ́106 cells/cm2 with EGM-2MV supplemented with 5% FBS using depletion technique (40% as compared to 20% by Hill's technique) was found to be optimal for culturing EPCs. Further, depletion technique yielded cobblestone EPCs in 28% of rabbit samples as compared to 40% of human blood specimens in three different patterns blood-island like cell culture (central lEPCs and peripheral early EPCs), biphasic EPCs (early EPCs and late EPCs), and de novo EPCs (late EPCs only). Homogenous rEPCs and hEPCs were sorted using CD34+CD133+ and CD34+VEGFR-2+ antibody. Further, with FACS analysis, rCD34+CD133+EPCs were found to be one third (3%) as compared to human CD34+CD133+EPCs (12%). These CD34+CD133+ rEPCs/hEPCs were double-positive for acLDL uptake, ULEX binding, CD34, CD309, and CD31; whereas negative for CD133, CD14 and CD45. Also, EPCs from both species demonstrated functional characterization. ConclusionsrCD34+CD133+EPCs in general, were mostly similar to human CD34+CD133+EPCs in proliferative potential, functional characterization, and phenotypic identity. However, the rEPCs appeared to be larger, expressed higher phenotype expression, higher NO production, and had a significantly thicker junctional area, tube thickness, and longer tubule length (P<0.05).
DESIGN OF BULBOUS BOWS

There is no doubt that bulbous bows improve most of the properties of ships, but the correct design and power prediction for ships with bulbous bows are still difficult due to the lack of design data. In the paper, a quantitative design method is presented together with the necessary data providing relationships between performance and main parameters of ships and bulbs. The data, in the form of design charts, are derived from a statistical analysis of routine test results of the Hamburg and the Berlin Model Basins, HSVA and VWS, respectively, supplemented by results of additional tests to fill the gaps. Three main hull parameters are taken into account: block coefficient, length/beam ratio, and beam/draft ratio, while six bulb quantities are selected and reduced to bulb parameters, of which the volume, the section area at the fore perpendicular, and the protruding length of the bulb are the most important. For power evaluation, the total power is subdivided into a frictional and a residual part. Depending on bulb parameters and Froude number for each block coefficient of the main hull, six graphs of residual power reduction have been prepared. Because of the wide range of block coefficients, there are so many design charts that only one example is presented herein.

Characterising the first year cohort knowledge

Over the past 5 years, the incoming engineering cohort at The University of Queensland has changed significantly in terms of both size and competence. Concerns have been raised by academics teaching courses in the first year engineering curriculum, as it is apparent that there is a misalignment between the level of competency in maths and science that academics assume the students possess, the skills sets that students actually possess, and the skills required to successfully navigate through first year engineering. A pilot on-line competency test, encompassing chemistry, physics, mathematics, and thermodynamics was run at the beginning of first semester 2009. The results were used to inform first year lecturers of the cohort knowledge base, and underpin future work which will support 'at-risk' students. This paper details preliminary results, the feedback obtained from staff and students, and ongoing research.
PREDICTED COMFORT ENVELOPES FOR OFFICE BUILDINGS WITH PASSIVE DOWNDRAUGHT EVAPORATIVE COOLING

Passive Downdraught Evaporative Cooling is a low energy strategy for maintaining thermal comfort in buildings located in hot dry climates. The thermal performance of such buildings can be predicted using simulation models. The temperatures predicted can be compared with standard comfort envelopes which show the range of temperatures and relative humidities within which occupants will be thermally comfortable. Standard comfort envelopes do not account for the adaptive opportunity which is important in free-floating buildings. Such adaptation could include changing clothing levels, local air speed (e.g. by using of fans) and solar radiation (by use of shading devices). A state of the art dynamic heat transfer and thermal comfort simulation model has been used to develop new comfort envelopes based on the adaptive behaviour theory. These "adaptive comfort envelopes" indicate occupants will be satisfied over a wider range of environmental conditions. The work indicates that increasing local air speeds is particularly effective in improving comfort when occupants are exposed to solar radiation.
A constraint-led approach to coaching cricket

Traditional approaches to skill development in cricket have been based around the ubiquitous net session and in particular an emphasis on the acquisition of the perfect technique. More recently, some coaches have taken ideas from sports science and attempted to use them to guide their practice. Some of these mono-disciplinary strategies have resulted in a reduction of „performance‟ into separate building blocks (e.g. technical, tactical, physical and mental skills), which can be worked on in isolation before the whole (performance) is stitched back together again. Each of these units is then broken down again. For example, batting is broken down into sub-phases to develop „hitting mechanics‟ via use of drop feeds, throw-downs and by use of bowling machines, while, for bowlers the run-up and bowling action are practiced separately. A major problem of this approach is the strong focus on technique development at the expense and in isolation from perception and decision-making skills. Although, for many coaches this intuitively makes sense because it simplifies learning into manageable bites, some experienced high level coaches have been highly critical of this specific contribution of sport scientists and suggested that cricket needed a serious debate to determine whether these new methods are in fact more efficient and better than the methods of the past (e.g., Chappell, 2004). In 2004 we responded to these comments and were in general agreement with the sentiments of Chappell. We pointed out that perhaps the main problem with the approach of the scientists was the relative usefulness of the theoretical model they were basing their work upon and that recent research was highlighting the importance of a holistic, multi-disciplinary approach to skill development (Renshaw et al., 2004). Since then, our research using cricket bowling and batting has shown us that the development of appropriate technique requires learners to practice tasks where perception and action are maintained via environments representative of the competitive performance (Renshaw & Davids, 2006; Renshaw et al., 2007). This view suggests that performance is a function of the interaction of unique individuals with specific task and environmental constraints. In the rest of this article we describe the constraint-led approach and suggest that it is a suitable theoretical model that coaches and scientists can utilise to underpin learning design.

The Lagrangian Coordinates and What it Means for First Order Traffic Flow Models

The aim of this paper is to go further into the N-function by formulating the LWR model in the transformed coordinate system. These Langrangian coordinates are fixed to a given fluid particle and more with it in space-time. The paper is organized as follows: Section 2 formulates the LWR model in Lagrangian coordinates as a conservation law and as a variational principle; it also derives relevant numerical schemes. Section 3 analyses the errors introduced by the Gudunov scheme in Eulerian coordinates in order to gain some insights about its nature. Section 4 show how to implement existing and novel extensions using the Langranian approach and section 5 presents a discussion.
Evaluating Information Systems: Public and Private Sector

The adoption of Information Technology (IT) and Information Systems (IS) represents significant financial investments, with alternative perspectives to the evaluation domain coming from both the public and private sectors.As a result of increasing IT/IS budgets and their growing significance within the development of an organizational infrastructure, the evaluation and performance measurement of new technology remains a perennial issue for management. This book offers a refreshing and updated insight into the social fabric and technical dimensions of IT/IS evaluation together with insights into approaches used to measure the impact of information systems on its stakeholders. In doing so, it describes the portfolio of appraisal techniques that support the justification of IT/IS investments. Evaluating Information Systems explores the concept of evaluation as an evolutionary and dynamic process that takes into account the ability of enterprise technologies to integrate information systems within and between organisations. In particular, when set against a backdrop of organisational learning. It examines the changing portfolio of benefits, costs and risks associated with the adoption and diffusion of technology in today's global marketplace. Finally approaches to impact assessment through performance management and benchmarking is discussed. * A unique reference work and examination of the IS evaluation 'life-cycle' * An holistic treatment of the subject beyond the normal prescriptive 'investment appraisal' approaches that reflects recent developments in the field* Essential text for students on business information systems courses and an insightful resource for professionals engaged in justifying IT/IS expenditure
[Time-Trends in Cervical Cancer Mortality in Portugal].

INTRODUCTION The mortality rate due to cervical cancer is higher in Portugal compared to other European countries. This study aimed to evaluate the time-trends in cervical cancer mortality rates observed in Portugal over the last six decades. MATERIAL AND METHODS Age-standardized cervical cancer mortality rates reported in Portugal between 1955 and 2014, were collected from the International Agency for Research on Cancer (IARC). Joinpoint regression analysis was used to identify significant changes in mortality rates by assessing the percentage of annual variation (%AV) of the rate and respective 95% confidence interval (95%CI) according to the age groups. RESULTS Among women with 30-39 years, cervical cancer mortality decreased 1.9% per year (95%CI: -2.3; -1.4) throughout the time-period, reaching 0.5/100 000 in 2014. Among women aged 40-49 years, CC mortality decreased between 1971 and 1981 (%AV = -11.6; IC 95%: -14.6; -8.6). Rates then increased by 2.4% per year (95%CI: 1.0; 3.8) until 2001 and such trend reverted from 2001 onwards (%AV = -5.2; IC 95%: -7.7; -2.6), reaching 3.0/100 000 in 2014. In women aged 50-64, 65-74 and 75 years or older, cervical cancer mortality rates decreased from 29.2 to 6.7/100 000, from 34.3 to 7.7/100 000 and from 24.7 to 9.2/100 000. The decline in mortality rates in these three age groups occurred mainly between 1970 and 1980, and there have been no significant changes in the last three decades. DISCUSSION In Portugal, the most impressive decline in cervical cancer mortality rates occurred in the 1970s concurrently with changes in the National Healthcare System. The most important changes were the increased access to early diagnosis and the improvement in therapeutic approaches. The plateau that we observed among older women over the last three decades can be partially explained by factors with negative impact on adherence to cervical screening. CONCLUSION There was a marked decrease in mortality due to CC among all age groups. However, we observed a plateau of this indicator in more advanced age groups over the last three decades. These findings suggest the need of promoting adherence to cervical screening in Portugal.
Making ICT Initiatives More Relevant: Creating Spaces for Farmers’ Participation in ICT Policies in the Philippines

There is a tendency for participation to be sidetracked in the highly infrastructure-centric discourse on information and communication technology for development (ICT4D). For some time, views anchored on technological determinism have dominated the discourse. Technology has been viewed as a “magic wand” that will serve as the answer to most development concerns. The discourse, however, has evolved as many ICT4D scholars have pushed for the social dimension of ICTs. It has been argued that if ICTs were to create significant impacts on the lives of the poor and the marginalised, ICT applications must stem from the identified needs of the community, and not just on the “global need” to modernize (Mansell, 2006). Heeks and Molla (2009) argue the interest on ICT4D studies has already shifted from readiness to impact. Readiness refers to the availability of the necessary ICT infrastructure to support ICT initiatives, while impacts focus on the value-added or the development contributions of ICTs (Heeks and Molla, 2009). All this is rooted from the growing discussion on the need to capture the development impact of multi-million dollar investments on ICT projects. We will argue in this paper that participation especially of the primary stakeholders in ICT projects is imperative if ICTs are to create significant impacts in their lives. Genuine participation, not tokenistic, will allow spaces for participation of the members of the community, which will result in more relevant ICT initiatives. It is hoped that by meticulously executing participatory mechanisms, pseudo-participation, which is unwittingly entrenched in many development projects worldwide, can be avoided. Pseudo-participatory mechanisms are rampant such that scholars have called for investigation of projects that purport to be participatory (Thomas, 2006). In this paper, we will proceed by first presenting the findings of the two research studies on ICT4D in Philippine agriculture commissioned by the Philippine Rice Research Institute (PhilRice). We will use these studies as take off points for the justification of the participatory mechanisms that we will forward in this paper. The studies, both national in scope, could lend methodological recommendations to assessing ICT for agriculture initiatives. To further strengthen our proposal, we will likewise present some ICT4D experiences from other countries that tried to employ the participatory approach. We attribute to a significant extent our appreciation of participatory communication to the works of Bessette (2004), Mefalopulos (2008) and Tufte (2009). We will also present some ways on how to make ICTs inclusive.
