El ponqué Chocoramo y la teoría de la innovación como factor de éxito

Existen en la mente muchos recuerdos y aquellos que marcan aun más son aquellos de la niñez. Para muchos colombianos el Chocoramo hace parte de esos recuerdos; ya sea en la lonchera, en recreos, o en la alacena de casa. Esta porción de ponqué cubierta con chocolate representa algunas de las cosas que los colombianos apreciamos. El Chocoramo es un ponqué simple, tradicional, fresco, rico y conveniente para calmar el hambre cuando no el tiempo es escaso. Por lo que significa, por hacer parte de nuestros recuerdos y porqué crecimos comiendo Chocoramo; sin duda alguna este ponqué de empaque naranja hace parte de la tradición colombiana. Si bien la innovación continua en empaque y producto se convierte en la clave del éxito para muchas de las firmas, Productos Ramo nos enseña que no podemos olvidar quienes son nuestros clientes y cuál es la razón por la que aprecian nuestros productos, para el consumidor del ponqué Chocoramo significa mucho más que un lindo empaque.

Critical success factors for competitiveness of contractors: A China study

Gaining or maintaining a “contractor's” competitive advantage is not easy as it is determined by a large number of factors. Identification of critical success factors (CSFs) allows one to reduce the vast number of factors to some manageable few but vital ones. Based on the CSFs, contractors' limited resources such as money and manpower can be allocated and aligned appropriately for yielding a maximum outcome of overall competitiveness. This paper describes the CSFs identified from a survey study carried out in Mainland China. The ranking analysis of the survey results shows that 35 factors are rated as critical for determining the competitiveness of a contractor. Factor analysis reveals that the 35 CSFs identified can be grouped into eight clusters, namely, project management skills, organization structure, resources, competitive strategy, relationships, bidding, marketing, and technology. The CSFs in this study provide a vehicle for guiding a contractor in managing its resources in order to improve competitive advantage. The study also provides insights into the management of competitiveness for contractors that are operating in the particular context of the Chinese construction industry.

Success and failure of grassroots innovations for addressing climate change: the case of the Transition Movement

Grassroots innovations emerge as networks generating innovative solutions for climate change adaptation and mitigation. However, it is unclear if grassroots innovations can be successful in responding to climate change. Little evidence exists on replication, international comparisons are rare, and research tends to overlook discontinued responses in favour of successful ones. We take the Transition Movement as a case study of a rapidly spreading transnational grassroots network, and include both active and non-active local transition initiatives. We investigate the replication of grassroots innovations in different contexts with the aim to uncover general patterns of success and failure, and identify questions for future research. An online survey was carried out in 23 countries (N=276). The data analysis entailed testing the effect of internal and contextual factors of success as drawn from the existing literature, and the identification of clusters of transition initiatives with similar internal and contextual factor configurations. Most transition initiatives consider themselves successful. Success is defined along the lines of social connectivity and empowerment, and external environmental impact. We find that less successful transition initiatives might underestimate the importance of contextual factors and material resources in influencing success. We also find that their diffusion is linked to the combination of local-global learning processes, and that there is an incubation period during which a transition initiative is consolidated. Transition initiatives seem capable of generalising organisational principles derived from unique local experiences that seem to be effective in other local contexts. However, the geographical locations matter with regard to where transition initiatives take root and the extent of their success, and ‘place attachment’ may have a role in the diffusion of successful initatives. We suggest that longitudinal comparative studies can advance our understanding in this regard, as well as inform the changing nature of the definition of success at different stages of grassroots innovation development, and the dynamic nature of local and global linkages.

Teledermatology : the case of telemedicine adoption and success in New Zealand

Using a theoretical framework extracted from thetechnological innovation theories, this research attempts to explain factors influencing the adoption and diffusion of telemedicine utilising the video conferencing technology (TMVC) for dermatology within health Waikato (HW) in New Zealand. Findings indicate weak presence of critical assessment into technological innovation factors prior to TMVC adoption. Factors such as complexity, compatibility, and trialability were not assessed extensively by HW and could have hindered its adoption. TMVC was mainly assessed according to its relative advantage and cost effectiveness. This is essential but should consider other important factors explained in this research. The successful diffusion of TMVC in the case study relied on its economical benefit and on its effectiveness as a diagnostic tool. This research highlights the importance of the product champion factor on the successful adoption and diffusion of TMVC.

Flexible delivery in the Australian vocational education and training sector: Barrier to success identified in cases studies of four adult learners

Government policy in Australia is increasingly encouraging training organisations in the Vocational Education and Training (VET) sector to adopt flexible delivery approaches, but some researchers are sounding a note of caution. Evidence is emerging that Australian VET learners are not universally ready for flexible delivery, and this is reflected in high attrition rates and low pass rates. The literature on flexible delivery identifies a number of specific factors that can impact on the success of adult learners. However, there seems to be agreement that failure or dropout is not determined by a single factor, but by the interaction of a number of factors that build up over time. To understand these factors, we need to understand the learners - what their participation in education means to them, the context in which they are studying, and the numerous inter-connected factors that contribute to their failure to achieve a successful outcome. This paper discusses four case studies from a research project that followed up a small number of adult learners who enrolled in flexible delivery VET courses but did not achieve a successful outcome.

A mechanistic study on reduced toxicity of irontecan by coadministered thalidomide, a tumor necrosis factor-a inhibitor

Dose-limiting diarrhea and myelosuppression compromise the success of irinotecan (7-ethyl-10-[4-[1-piperidino]-1-piperidino] carbonyloxycamptothecin) (CPT-11)-based chemotherapy. A recent pilot study indicates that thalidomide attenuates the toxicity of CPT-11 in cancer patients. This study aimed to investigate whether coadministered thalidomide modulated the toxicities of CPT-11 and the underlying mechanisms using several in vivo and in vitro models. Diarrhea, intestinal lesions, cytokine expression, and intestinal epithelial apoptosis were
monitored. Coadministered thalidomide (100 mg/kg i.p. for 8 days) significantly attenuated body weight loss, myelosuppression, diarrhea, and intestinal histological lesions caused by CPT-11 (60 mg/kg i.v. for 4 days). This was accompanied by inhibition of tumor necrosis factor-, interleukins 1 and 6 and interferon-, and intestinal epithelial apoptosis. Coadministered
thalidomide also significantly increased the systemic exposure of CPT-11 but decreased that of SN-38 (7-ethyl-10-hydroxycampothecin). It significantly reduced the biliary excretion and cecal exposure of CPT-11, SN-38, and SN-38 glucuronide. Thalidomide hydrolytic products inhibited hydrolysis of CPT-11 in rat liver microsomes but not in primary rat hepatocytes. In addition, thalidomide and its major hydrolytic products, such as phthaloyl glutamic acid (PGA), increased the intracellular accumulation of CPT-11 and SN-38 in primary rat hepatocytes. They also significantly decreased the transport of CPT-11 and SN-38 in Caco-2 and parental MDCKII cells. Thalidomide and PGA also significantly inhibited P-glycoprotein (PgP/MDR1), multidrug resistance-associated protein (MRP1)- and MRP2-mediated CPT-11 and SN-38 transport in MDCKII cells. These results provide insights into the pharmacodynamic and  pharmacokinetic mechanisms for the protective effects of thalidomide against CPT-11-induced intestinal toxicity.

Long-term risk factor control after a cardiac rehabilitation programme

This study examined the hypothesis that Phase II cardiac rehabilitation participants (CRP) had better long-term risk factor control, self-rated perception of health and return to work rates than non-participants (NP) between 18 and 36 months post myocardial infarction (MI). It was a comparative study in a 550 bed hospital.

Approximately half of both groups did not achieve a total cholesterol (TC) of 5.5mmol/L or less. Compared with NP, CRP were significantly more likely to have a TC<=6.5mmol/L (7% vs. 28%) (p=0.006). NP with TC>6.5mmol/L were significantly less likely to be on treatment (p=0.002). CRP were more likely to regularly exercise than NP (79% vs. 61%) (p=0.038). The success rate for blood pressure targets, return to work rates and self-rated perception of health were similar in both groups.

In conclusion, CRP had better long-term control of some risk factors than NP. The study provides comparative longer term patient outcomes after an Australian cardiac rehabilitation (CR) programme and forms the basis for further outcome measurement.

Is adiposity an under-recognized risk factor for tendinopathy? A systematic review

Objective : Tendon injuries have been reported to occur more frequently in individuals with increased adiposity. Treatment also appears to have poorer outcomes among these individuals. Our objective was to examine the extent and consistency of associations between adiposity and tendinopathy.

Methods : A systematic review of observational studies was conducted. Eight electronic databases were searched (Allied and Complementary Medicine, Biological Abstracts, CINAHL, Current Contents, EMBase, Medline, SPORTDiscus, and Web of Science) and citation tracking was performed on included reports. Studies were included if they compared adiposity between subjects with and without tendon injury or examined adiposity as a predictor of conservative treatment success.

Results : Four longitudinal cohorts, 14 cross-sectional studies, 8 case-control studies, and 2 interventional studies (28 in total) met the inclusion criteria, providing a total of 19,949 individuals. Forty-two subpopulations were identified, 18 of which showed elevated adiposity to be associated with tendon injury (43%). Sensitivity analyses indicated a clustering of positive findings among studies that included clinical patients (81% positive) and among case-control studies (77% positive).

Conclusion : Elevated adiposity is frequently associated with tendon injury. Published reports suggest that elevated adiposity is a risk factor for tendon injury, although this association appears to vary depending on aspects of study design and measurement. Adiposity is of particular interest in tendon research because, unlike a number of other reported risk factors for tendon injury, it is somewhat preventable and modifiable. Further research is required to determine if reducing adiposity will reduce the risk of tendon injury or improve the results of treatment.

Male and female effects on fertilization success and offspring viability in the Peron's tree frog, Litoria peronii

There is increasing theoretical and empirical evidence that genetic compatibility among partners is an important determinant of fertilization success and offspring viability. In amphibians, females often actively choose partners from among a variety of males and polyandry is common. Genetic compatibility among partners may therefore be an important determinant of fertilization success and offspring viability in some amphibians. Amphibians also show some of the highest levels of genetic differentiation among neighbouring populations known in vertebrates, and as such, populations may have evolved different co-adapted gene complexes. This means that offspring from among-population crosses may have reduced fitness. It is therefore essential to understand to what extent crossings between and within populations may interfere with successful fertilization and offspring viability. Here, we test whether crossing individuals within and between two different populations of the Australian Peron's tree frog (Litoria peronii) using artificial fertilizations affect fertilization success and offspring viability. Fertilization success per se is strongly influenced by male identity, which is likely to depend at least to some extent on the experimental procedure (e.g. resulting in variation in sperm number per ejaculate), whereas there was no fertilization effect of female identity. More importantly, male and female identity, independently of each other, explained significant variation in offspring viability, whereas no such effect could be linked to population of origin. Thus, our experiments suggest that crossing populations may not always be the most significant factor affecting fertilization success or offspring viability, but may be more influenced by the genetic quality or the genetic compatibility of partners.

Critical success factors for stakeholder management: construction practitioners' perspectives

Although various factors have been identified as important for accomplishing successful stakeholder management, few studies appear to have undertaken a comparative analysis of practitioners’ views on the relative importance of critical success factors (CSFs) for stakeholder management in construction projects. In an attempt to fill this research gap, a questionnaire survey was conducted in Hong Kong to collect the opinions of construction practitioners regarding the relative importance of CSFs for stakeholder management. Findings from this study show that all 15 selected CSFs are regarded as critical by most respondents for the success of stakeholder management in construction projects. The factor regarding social responsibilities is considered most important for managing stakeholders. Although correlations between CSFs and types of projects and organizations were statistically significant, these were not particularly strong. Also, even though there is a general consensus on the rankings of the CSFs among different respondents, the detailed pairwise comparisons actually show the existence of a few differences in perceptions on the relative importance of the CSFs. Therefore, the working priorities of project managers for managing stakeholders are context specific, depending on the nature, client sector, and cost of the project, and also on their organizations and management levels in the organization. These findings should help project managers become more aware of their responsibilities and the relative importance of issues for management stakeholders.

Exploring critical success factors for stakeholder management in construction projects

With a focus on different aspects of stakeholder management, various sets of critical success factors (CSFs) have been suggested in the literature. It is crucial to explore the relative importance and groupings of these factors. This paper aims to identify CSFs associated with stakeholder management in construction projects, and explore their ranking and underlying relationship. 15 CSFs were identified through a literature review, and consolidated by interviews and pilot studies with professionals in construction industry. A questionnaire instrument containing these 15 CSFs was sent out to project managers in Hong Kong, and 183 completed questionnaires were retrieved. The top three ranked factors for stakeholder management were "managing stakeholders with social responsibilities", "assessing the stakeholders' needs and constraints to the project", and "communicating with stakeholders properly and frequently". Using factor analysis and considering the high importance of the factor "managing stakeholders with social responsibilities", the 15 CSFs were grouped into five dimensions namely, precondition factor, stakeholder estimation, information inputs, decision making, and sustainable support. All these five groupings and their relationship were included in a framework for successful stakeholder management in construction projects. These findings help to clarify what the high prioritized factors are, and could also be used as an assessment tool to evaluate the performance of stakeholder management and thus help to identify areas for improvement.

Factor analysis of partners' commitment to risk management in public-private partnership projects

Purpose – The purpose of this paper is to investigate and uncover key determinants that could explain partners' commitment to risk management in public-private partnership projects so that partners' risk management commitment is taken into the consideration of optimal risk allocation strategies.

Design/methodology/approach – Based on an extensive literature review and an examination of the purchasing power parity (PPP) market, an industry-wide questionnaire survey was conducted to collect the data for a confirmatory factor analysis. Necessary statistical tests are conducted to ensure the validity of the analysis results.

Findings – The factor analysis results show that the procedure of confirmatory factor analysis is statistically appropriate and satisfactory. As a result, partners' organizational commitment to risk management in public-private partnerships can now be determined by a set of components, namely general attitude to a risk, perceived one's own ability to manage a risk, and the perceived reward for bearing a risk.

Practical implications – It is recommended, based on the empirical results shown in this paper, that, in addition to partners' risk management capability, decision-makers, both from public and private sectors, should also seriously consider partners' risk management commitment. Both factors influence the formation of optimal risk allocation strategies, either by their individual or interacting effects. Future research may therefore explore how to form optimal risk allocation strategies by integrating organizational capability and commitment, the determinants and measurement of which have been established in this study.

Originality/value – This paper makes an original contribution to the general body of knowledge on risk allocation in large-scale infrastructure projects in Australia adopting the procurement method of public-private partnership. In particular, this paper has innovatively established a measurement model of organisational commitment to risk management, which is crucial to determining optimal risk allocation strategies and in turn achieving project success. The score coefficients of all obtained components can be used to construct components by linear combination so that commitment to risk management can be measured. Previous research has barely focused on this topic.

Learning to think, learning to learn : super teaching for super success

The early childhood years are a busy, exciting time. New discoveries, skills and competencies are a regular part of life for a young child. Early childhood teachers have the opportunity to optimise these amazing and important years. In this paper, I will discuss teaching strategies that can turn children’s possibilities into realities. The practices that will be discussed involve expanding thinking, problem-solving and developing hypotheses. These teaching strategies can build on children’s learning dispositions and their strengths and interests to put the ‘wow factor’ into learning.

Integrating the human factor into the holistic understanding of sustainability

Using a number of literary sources with sustainable design and architectural phenomenology as their foundation, this paper uses Integral theory, drawing on the writings of Ken Wilber and Mark DeKay to justify the importance of human architectural experience in the holistic view of sustainable design. The literature critiques modern practices and ideas of sustainability and identifies factors that contribute towards the success of sustainable building. It explores the implications for an Integral approach to sustainable design and then uses it to analyse the relationships that exist between the objective and the subjective value spheres of Integral theory.
