The growing caseload of chronic life-long conditions calls for a move towards full self-management in low-income countries
Josefien van Olmen, Grace Ku, Raoul Bermejo, Guy Kegels, Katharina Hermann, Wim Van Damme
Globalization and Health , 2011, DOI: 10.1186/1744-8603-7-38
Abstract: The aim of this paper is to show that present provider-centred models of chronic care are not adequate and to propose 'full self-management' as an alternative for low-income countries, facilitated by expert patient networks and smart phone technology.People with chronic life-long conditions need to 'rebalance' their life in order to combine the needs related to their chronic condition with other elements of their life. They have a crucial role in the management of their condition and the opportunity to gain knowledge and expertise in their condition and its management. Therefore, people with chronic life-long conditions should be empowered so that they become the centre of management of their condition. In full self-management, patients become the hub of management of their own care and take full responsibility for their condition, supported by peers, professionals and information and communication tools.We will elaborate on two current trends that can enhance the capacity for self-management and coping: the emergence of peer support and expert-patient networks and the development and distribution of smart phone technology both drastically expand the possibilities for full self-management.Present provider-centred models of care for people with chronic life-long conditions are not adequate and we propose 'full self-management' as an alternative for low-income countries, supported by expert networks and smart phone technology.The problem of chronic diseases has risen up the agenda of global health policy makers in recent years [1-6]. The growing numbers of patients with Chronic Life-Long Conditions (CLLC), such as diabetes and hypertension, puts an immense burden on health systems and populations, because of increased needs for health care providers and steadily rising costs of health care services.The present response of health systems, both in high and in low income countries, is highly inadequate. The professionalised models of chronic care that have been developed
Does Reactive Adaptation Exist? Using the Ecosystem Service Governance Approach to Evaluate Post-Drought Rural Food Security in Kenya  [PDF]
Grace W. Ngaruiya
Natural Resources (NR) , 2014, DOI: 10.4236/nr.2014.58037
Controversial climate change studies purport that predicted food insecurity and resource scarcity will intensify resource conflicts in developing nations. This belief is based on a prevalent assumption that African agricultural production systems are rigid and that their respective governments lack comprehensive adaptation ability. Therefore, I investigate whether and how effective post- drought adaptation activity is sustaining food production and livelihoods at Loitoktok district in Kenya. This study uses the theoretical three-step ecosystem service governance approach that analyzes both natural resources attributes and relational data. Results confirm a substantial decline in productivity and huge monetary losses in the agricultural sector of Loitoktok following the 2009 drought. Post-drought analysis reveals high diversification in crops and livestock that are drought-tolerant, fast maturing and high income generating such as camels, rabbits and dairy goats, horticultural and fruit production that sustain food security, income and local livelihoods. These reactive adaptation activities originate from an active public-private cooperation that promotes knowledge exchange among Loitoktok stakeholders. This cooperation is also seen in the efficient resource conflict resolution network. In conclusion, rural communities seem to be efficiently adapting to changing environmental conditions but require more financial and technical support from the government. Unfortunately, appraisal of national planned adaptation reveals effort-duplication that may divert much needed adaptation funds from being invested in research projects with multiple benefits to Kenyan food producers.
Testing the Effect of Soil Heterogeneity on Arbuscular Mycorrhiza Fungi (AMF) Contribution to Plant Productivity  [PDF]
Samuel Ayesu, Grace Gyabaah
Open Journal of Ecology (OJE) , 2014, DOI: 10.4236/oje.2014.46028

Most natural soils are heterogeneous and nutrient availability and soil structure change greatly over small distances. It is still unclear whether AMF are advantageous for plants under such heterogeneous soil conditions. The objective of this study was to determine whether diverse AMF community support host plant community productivity in heterogeneous soil. It was also tested whether soil heterogeneity affects plant productivity. This was carried out in a greenhouse experiment made up of two factors: soil heterogeneity and AMF richness. Soil heterogeneity was simulated by mixing three soil types (sand, field soil and organic soil) together (homogenous soil (HM)), mixing them partly (semi homogenous (SH)) or keeping the three soil types separate in three compartments within one pot (heterogeneous (HT)). AMF richness was simulated by adding no AMF, one of four different AMF species separately, or all four different AMF together. The pots were planted with a mixture of Trifolium pratense and Lolium multiflorum. There was no effect of soil heterogeneity on total plant biomass. However, the biomass of the individual plant species was greatly affected by soil heterogeneity with Lolium being the most abundant in the heterogeneous soil and Trifolium being the most abundant in the homogenous soil. Total plant biomass did not increase with AMF richness. Moreover, opposite to the hypothesis, AMF richness was not beneficial for plant productivity in a heterogenous soil environment. However, there were significant differences in plant biomass with different AMF treatments in the SH and HT treatment indicating that effects of AMF on plant productivity are influenced by soil type. These effects on yield and AMF reflect a combination of local responses to growing conditions. The results show that AMF influence on plant yield may not always be positive but is strongly dependent on ecological elasticity and environmental condition.

The Universality of the Portrayal of Gender in Television Advertisements: An East-West Comparison  [PDF]
Grace Lim, Adrian Furnham
Psychology (PSYCH) , 2016, DOI: 10.4236/psych.2016.713154
Abstract: This study compared portrayals of gender in Malaysian and British television advertisements regarding the portrayal of men and women across these two countries. A total of 236 advertisements were content analyzed for nine variables relating to the primary character of the advertisement. The findings provide evidence of gender stereotyping in both countries for types of products advertised, credibility and role of the primary characters. The results suggest that portrayals in British advertisements are similar to those in Malaysian advertisements despite the cultural gap. These findings are discussed in relation to implications and the limitations of the study are noted.
Virtues in Clinical Practice: Teaching Students about the Complexities and Depth of Professional Practice  [PDF]
Sandra Grace, Airdre Grant
Creative Education (CE) , 2017, DOI: 10.4236/ce.2017.813143
Abstract: This paper investigates the integration of virtues into teaching programs for allied health students. It explores the notion that practitioners’ effectiveness is enhanced when they practice virtues along with their technical expertise. These virtues include wisdom and love and they imbue the practitioner’s role with a meaning that extends beyond efficient diagnosis and competent case management. Practicing virtues can deepen the clinical relationship. Allied health students may feel cautious and uncertain about what it actually means to be a virtuous practitioner. Reflexive practice and dialogic encounters are presented as teaching activities that can cultivate virtuous practice.
Telomeres and Telomerase: Molecular Views and Perspectives  [PDF]
Kumar Arvind, Tony Grace
Advances in Aging Research (AAR) , 2018, DOI: 10.4236/aar.2018.75008
Abstract: Telomere, the nucleoprotein structure at the end of eukaryotic linear chromosomes is indispensable for maintaining the genome stability. Telomeric DNA loss is apparent with each cell division, which marks an endpoint to the indefinite replication of the cell by causing replicative senescence that may lead to the programmed cell death. The loss of telomere is normal in cell division and as such after 20 - 40 divisions, telomere becomes too short to facilitate the capping function. Telomere uncapping or chromosomal free end causes a potential threat to the genomic stability and thus leads to the accumulation of chromosomal abnormalities that have been known to play a role in aging and cancer. Telomerase, the ribonucleoprotein complex, and its accessory proteins are required to maintain the telomere sequence. Telomerase plays a key role in maintaining the length of telomere by adding G-rich repeat sequences. Its activity has been found to be quite high in the gametes, stem cells and most importantly tumor cells. Almost 85% of tumor cells compensate for telomere loss aided by telomerase-associated protein complex and shelter in complex or telosome. However, 5% - 10% of the cells undergo telomerase-independent mechanism. This review presents the molecular view of the telomere and telomerase along with its associated complex structures. It also discusses its contrasting role in causing cellular senescence and promoting tumorigenesis.
Dynamical Model with Application to the Analysis of the Sweet Spot on a Baseball Bat  [PDF]
Li Cheng, Zaiqiang Ku
American Journal of Computational Mathematics (AJCM) , 2015, DOI: 10.4236/ajcm.2015.54040

In this paper, we analyze the effect on the ball-bat model of corking the bat, and investigate the relationship between the sweet spot and different materials. First and foremost, we develop a simple but effective theoretical model to give a rough estimate for the sweet spot of the bat. Second, we give a simplified abstract form of bat which facilitates the description and modeling study. Last but not least, according to different material caused rotary inertia and different recovery coefficient, researches on the different material hitting effect were made.

Intelligent Urban Sustainable Development Plan  [PDF]
Zaiqiang Ku, Ting Liao
Journal of Applied Mathematics and Physics (JAMP) , 2017, DOI: 10.4236/jamp.2017.55092
Abstract: Based on the entropy weight method and the gray relational analysis method, we first calculate the weight of each index and the correlation coefficient between the indicators, get the urban intelligent growth index, and then calculate the annual growth rate of the composite index. We find the following results. First, Suzhou to improve its environment, the success rate of 109.67%. Saint Louis to improve its economy, the growth rate of 57.4%. Second, the sensitivity of the data analysis, each of the indicators is increased by 10%, 20%, 30%, other indicators remain unchanged. Recalculate the city’s intelligent growth index, we find that the greater the volatility, the greater the potential. The total population of the city, built green area, the total length of the bus operating a greater potential, built-up area, the smallest regional GDP potential. Finally, we propose an improved model combining remote sensing with GIS to analyze urban expansion and farmland loss from time and space qualitatively and quantitatively.
The Effect of Self-Driving Car on Urban Traffic  [PDF]
Zaiqiang Ku, Ting Liao
American Journal of Computational Mathematics (AJCM) , 2017, DOI: 10.4236/ajcm.2017.72013
Abstract: Based on the idea of infinitesimal analysis, we establish the basic model of relation between speed and flow. Since putting a certain amount of self-driving car will affect the average speed of mixed traffic flow, we choose the proportion of self-driving car to be a variable, denoted by k. Based on the least square method, we find two critical values of k that are 38.63% and 68.26%. When k < 38.63%, the self-driving cars have a negative influence to the traffic. When 38.63% < k < 68.26%, they have a positive influence to the traffic. When k > 68.26%, they have significant improvement to the traffic capacity of the road.
The Shadow Of Past Rivalry: Limits Of Post-1999 Dynamism In Greco-Turkish Relations
Eda Kuku
Caucasian Review of International Affairs , 2008,
Abstract: This essay will enquire whether Turkey and Greece could remove their enduring controversies through confidence building measures, mediation and inter-governmental dialogues which were introduced in the post-1999 détente period. The paper will specifically focus on the recent nature of understanding between the two countries and will endeavour to answer the question of whether there is a divergence in the nature of recent cooperative arrangements from those which were concluded in the former periods of détente and each of which were disrupted by succeeding periods of either armed conflict or cold war. The paper contends that the recent nature of Greek-Turkish relations is not problem-free. Yet, the new cooperative environment facilitated by confidence building measures and growing mutual understanding could help resolve the disputes and dispel reservations in the Aegean and Cyprus which have been very central to national security considerations of both Turkey and Greece. From a security perspective, continuation of previous policies towards one another is counterproductive in the post-1999 period. Improvement of a bilateral dialogue under the EU umbrella is detrimental for the defence considerations of both Turkey and Greece.
