A Model for Building and Implementing Customer Value Co-creation Agendas

Engaging customers to co-create value is a key strategy for businesses that are competing to fulfil custom-made demands and to gain competitive edge. Nevertheless, research in the field of value co-creation is still in its infant stage. In the search for an innovative competitive strategy, the extant literature on customer value co-creation generally overlooked the implementation of the concept in the world of business. To fill the gap, the current paper proposes and discusses a framework of competencies and processes for developing and implementing co-creation programs in business organizations. By offering a modest, easy-to-understand framework, it takes the fear element out of embracing these new value-creation agendas, and advocates that companies should strive to get closer to customers and other stakeholders so as to lessen the distance by promoting participation and co-creation. The paper also discusses a critical precondition for adopting, effectively executing and harvesting the fruits of co-creation programs: a shift in leadership and management’s mind-set. New mind-sets and new cultures are necessary requirements for broadening one’s horizon and promoting creativity. Without that shift, the possibility of collaboration and co-creation is likely to be unconvincing, implausible and leaving customers apathetic and disengaged. This paper is among the first to suggest an implementation framework for the study of collaboration and value co-creation and has the potential to drive future research as well as guide companies interested in implementing the proposed framework. Keywords: Co-creation, collaboration, customer freedom and choice, interaction, cultivating relationships
Timing of granite emplacement and cooling in the Songpan – Garzê Fold Belt ( eastern Tibetan Plateau ) with tectonic implications

New U–Pb and Rb–Sr geochronology on synand post-orogenic granites provide constraints on the timing of major tectonic events in the Songpan–Garzê fold belt, west Sichuan, China. The Ma Nai granite was probably syn-kinematic with the main deformation and yields an age of 197 ^ 6 Ma that is interpreted as an upper age limit of the Indosinian event. Zircons and apatites from the post-kinematic Rilonguan granite also yield Jurassic ages (195 ^ 6 and 181 ^ 4 Ma). The post-orogenic Markam massif gives two ages of 188 ^ 1 and 153 ^ 3 Ma. Both granites are undeformed and cut structures in the Triassic sedimentary rocks. These results demonstrate that the major deformation and décollement tectonics in the Songpan–Garzê fold belt occurred prior to the Early Jurassic. The wide range of ages obtained for postkinematic granites (from Early Jurassic to Late Jurassic) suggests that, locally, magmatic activity persisted for a long time (at least 50 Ma) after the Indosinian compressional tectonism. No Tertiary ages have been obtained, suggesting that these granites were not affected strongly by the India–Asia collision. q 2003 Elsevier Ltd. All rights reserved.
On the role of the Barbero–Immirzi parameter in discrete quantum gravity

The one-parameter family of transformations identified by Barbero and Immirzi plays a significant role in non-perturbative approaches to quantum gravity, among them loop quantum gravity and spin foams. It facilitates the loop quantization programme and subsequently the Barbero–Immirzi parameter (γ) arises in both the spectra of geometrical operators and in the dynamics provided by spin foams. However, the debate continues as to whether quantum physics should be Barbero–Immirzi parameter dependent. Starting from a discrete SO(4)-BF theory phase space, we find two possible reductions with respect to a discrete form of the simplicity constraints. The first reduces to a phase space with γ-dependent symplectic structure and more generally in agreement with the phase space underlying loop quantum gravity restricted to a single graph—a.k. a. twisted geometries. The second, fuller reduction leads to a γ-independent symplectic structure on the phase space of piecewise-flat-linear geometries—a.k. a Regge geometries. Thus, the γ-dependence of physical predictions is related to the choice of phase space underlying the quantization.
Use of Monosaccharides in Metal-Catalyzed Coupling Reactions

The addition of monosaccharides to metal-catalyzed coupling reactions can be beneficial in terms of decreasing the time required, chemical waste products and overall cost of the process. Monosaccharides are used in a number of different ways, including (a) acting as a ligand for the metal, (b) providing the appropriate reduction potential for a chemical process and (c) acting as a reducing agent for the formation and stabilization of catalytically active metal nanoparticles. Recently, there has been a significant amount of research in this growing field and there is thus the potential for the addition of monosaccharides to coupling reactions to have a significant impact on the synthesis of the important small molecules on which we have all come to rely. This Perspectives Article will cover recent developments in the addition of monosaccharides to metal-catalyzed coupling reactions with an emphasis on their utility and limitations in order to facilitate the further development of this exciting area of rese.
Identification and Isolation of fungus from food and determination of its antibacterial activity

The issue of drug resistant pathogens is the most well-known issue now days. Irresistible and parasitic infections are still the second driving reason for death. This is the major cause to examine their antibacterial activity. The antimicrobial compounds produced by fungus naturally are the most vital source of their discovery. Parasites are easy and valuable source with the great pharmaceutical potential. This study was led to explore that whether the infectious metabolites have ability to repress or execute the human pathogenic microscopic organisms. The parasitic metabolites were segregated from Aspergillus niger , Aspergillus fumigatus , Aspergillus flavus , Rhizopus and Penicillium and check their antibacterial action against human pathogenic microorganisms, for example, Staphylococcus aureus, Streptococcus pyogenes and Pseudomonas aeroginosa. Zone of inhibition were measured by agar well diffusion method and pharmacological activity analyzed by qualitative test, for example, glycoside, alkaloid and tannins test. The results demonstrated that just Aspergillus fumigatus have pharmacological activity and it give zone of restraint against human pathogenic microbes. Other fungi for example, Aspergillus fumigatus, Aspergillus flavus, Aspergillus niger, Rhizopus and Penicillium did not give any zone of inhibition against Staphylococcus aureus, Streptococcus pyogenes and Pseudomonas aeroginosa. Aspergillus fumigatus metabolites can be use for the preparation of antibiotic.
Target And Kaizen Costing Implementation In Construction

The challenge of implementing a combined target and kaizen costing approach has been recognized as a promising strategy for construction companies seeking to increase their profit margins, efficacy of production process and relationship with suppliers. Construction companies use to perform their services in a competitive market and can apply this combination to reduce construction costs, while at the same time assuring their profitable business margins. This research sought to implement a combined target and kaizen costing approach along the planning and construction phases of brand retail units (BRU). A context specific case study with four BRU has been devised. The main idea was firstly to design and to specify the units to reduce historical product development costs by means of product’s definition interventions. On the target costing application the “customers care service center” of the company has been consulted about possible product conception interventions that were not perceived as value by customers. Later, the kaizen costing approach sought continuous improvements on production processes mostly based on suggestions originated by the main sub-contractors. The case study results show cost reductions around 13% compared with previous cost data of the company for these facilities.
Drying by spray drying in the food industry: Micro-encapsulation, process parameters and main carriers used

The process of spray drying consists of the transformation of a product in fluid form to the solid state in the form of powder. This is done through the dispersion of droplets from the product inside a chamber, in contact with hot air. In this process, substances known as carriers or encapsulating agents can be added, aiming at facilitating or even allowing the drying of certain products. The objective of this review was to approach the most important technological aspects of the drying by technique for the food industry, as well as showing the potential of using a spray dryer in the micro-encapsulation of bioactive substances. Key words: Spray dryer, encapsulating carrier agents, carriers, maltodextrin.
Organizational Culture in Business, Public and non Profit Sectors

Paper examines some issues of organizational cultural in the business sector entities, public administration and non for profit organizations. Survey is conducted via five dimensional model of Geert Hofstede and the four descriptions of organizational culture made by Tromenaars – Turnrer. There is one assumption razed for further exploration, based on the cultural background the examined non governmental organizations seems to be more enterpreneurship orientated compared the representatives of the other sectors.
Articulated structure from motion through ellipsoid fitting

We present a new method to reconstruct non-rigid objects from orthographic projections based on the assumption of articulated model. We introduce an ellipsoid property to identify points belonging to a rigid subset. This enables us to formulate the problem of motion segmentation as an ellipsoid fitting problem. The obtained rigid subsets are then linked as kinematic chains to constitute 3D articulated structure. This method is practical of computational complexity O(N) mainly based on linear least squares. We demonstrate the effectiveness of this method through experiments on real tracking data, motion capture data, and challenging human dataset with missing data, in comparison with existing methods.
Solution-processed organic tandem solar cells with embedded optical spacers

We demonstrate a solution-processed polymer tandem solar cell in which the two photoactive single cells are separated by an optical spacer. The use of an optical spacer allows for an independent optimization of both the electronic and optical properties of the tandem cell. The optical transmission window of the bottom cell is optimized to match the optical absorption of the top cell by varying the layer thickness of the optical spacer. The two bulk heterojunction subcells have complementary absorption maxima at λmax∼850nm for the top cell and λmax∼550nm for the bottom cell. The subcells are electronically coupled in series or in parallel using four electrical contacts. The series configuration leads to an open-circuit voltage of >1V, which is equal to the sum of both subcells. The parallel configuration leads to a high short-circuit current of 92A∕m2, which is equal to the sum of both subcells. The parallel configuration results in a much higher efficiency compared to the series configuration.
The debris-flow rheology myth

Models that employ a fixed rheology cannot yield accurate interpretations or predictions of debris-flow motion, because the evolving behavior of debris flows is too complex to be represented by any rheological equation that uniquely relates stress and strain rate. Field observations and experimental data indicate that debris behavior can vary from nearly rigid to highly fluid as a consequence of temporal and spatial variations in pore-fluid pressure and mixture agitation. Moreover, behavior can vary if debris composition changes as a result of grain-size segregation and gain or loss of solid and fluid constituents in transit. An alternative to fixed-rheology models is provided by a Coulomb mixture theory model, which can represent variable interactions of solid and fluid constituents in heterogeneous debris-flow surges with high-friction, coarse-grained heads and lowfriction, liquefied tails.

Design science research towards resilient cyber-physical eHealth systems

Most eHealth systems are cyber-physical systems (CPSs) making safety-critical decisions based on information from other systems not known during development. In this design science research, a conceptual resilience governance framework for eHealth CPSs is built utilizing 1) cybersecurity initiatives, standards and frameworks, 2) science of design for software-intensive systems and 3) empowering cyber trust and resilience. According to our study, a resilient CPS consists of two sub-systems: the proper resilient system and the situational awareness system. In a system of CPSs, three networks are composed: platform, software and social network. The resilient platform network is the basis on which information sharing between stakeholders could be created via software layers. However, the trust inside social networks quantifies the pieces of information that will be shared - and with whom. From citizens’ point of view, eHealth is wholeness in which requirements of information security hold true. Present procedures emphasize confidentiality at the expense of integrity and availability, and regulations/instructions are used as an excuse not to change even vital information. The mental-picture of cybersecurity should turn from “threat, crime, attack” to “trust” and “resilience”. Creating confidence in safe digital future is truly needed in the integration of the digital and physical world’s leading to a new digital revolution. The precondition for the exchange of information “trust” must be systematically built at every CPS’ level. In health sector, increasingly interconnected social, technical and economic networks create large complex CPSs, and risk assessment of many individual components becomes cost and time prohibitive. When no-one can control all aspects of CPSs, protection-based risk management is not enough to help prepare for and prevent consequences of foreseeable events, but resilience must be built into systems to help them quickly recover and adapt when adverse events do occur.
Visuospatial Processing De fi cits Linked to Posterior Brain Regions in Premanifest and Early Stage Huntington ’ s Disease

Objectives: Visuospatial processing deficits have been reported in Huntington’s disease (HD). To date, no study has examined associations between visuospatial cognition and posterior brain findings in HD. Methods: We compared 119 premanifest (55> and 64< 10.8 years to expected disease onset) and 104 early symptomatic (59 stage-1 and 45 stage-2) gene carriers, with 110 controls on visual search and mental rotation performance at baseline and 12 months. In the disease groups, we also examined associations between task performance and disease severity, functional capacity and structural brain measures. Results: Cross-sectionally, there were strong differences between all disease groups and controls on visual search, and between diagnosed groups and controls on mental rotation accuracy. Only the premanifest participants close to onset took longer than controls to respond correctly to mental rotation. Visual search negatively correlated with disease burden and motor symptoms in diagnosed individuals, and positively correlated with functional capacity. Mental rotation (“same”) was negatively correlated with motor symptoms in stage-2 individuals, and positively correlated with functional capacity. Visual search and mental rotation were associated with parieto-occipital (pre-/cuneus, calcarine, lingual) and temporal (posterior fusiform) volume and cortical thickness. Longitudinally, visual search deteriorated over 12 months in stage-2 individuals, with no evidence of declines in mental rotation. Conclusions: Our findings provide evidence linking early visuospatial deficits to functioning and posterior cortical dysfunction in HD. The findings are important since large research efforts have focused on fronto-striatal mediated cognitive changes, with little attention given to aspects of cognition outside of these areas.

Study on mosquito ovary using transmission electron microscopy

The study focuses on the ovaries of mosquito using transmission electron microscopy. Mosquito that were used comprised of six different strains, namely: Culex pipiens Complex, Aedes aegypti, Aedes vexans, Ochlerotatus cantans, Ochlerotatus rusticus collected from the Philippines and Germany. A meal of blood in the mosquito can alter a series of changes in the cell structure that leads to the formation of a mature egg. After the mosquito has taken a blood meal, some prominent changes occur in the epithelial follicles. The very prominent changes that occur are the development of large inter-cellular spaces and a decrease in desmosomal connections. Several numbers of microvilli covered the area of the oocyte facing the epithelial follicles of which during seven hour after blood meal, push towards the extra-cellular spaces created by the separation of the epithelial follicle cells. The microvilli vary in length and are not regularly distributed like those of the typical intestinal epithelium. A unit membrane is seen which later fuses to form a yolk. A meal of blood or controlled diet leads to a series of changes in cell structures in the reproductive organ of female mosquitoes that quickly results to the formation of matured eggs. Another prominent changes observed in the ovary of mosquitoes having blood meal is the presence of various un-oriented microvilli in the area of the oocyte which is adjacent to the epithelial follicles. These microvilli can also be observed in ovary of mosquitoes having no blood meal but they are smaller in size. Furthermore, pits or vesicular bodies are developed after a mosquito has taken a blood meal.

AMISEC: Leveraging Redundancy and Adaptability to Secure AmI Applications

Security in Ambient Intelligence (AmI) poses too many challenges due to the inherently insecure nature of wireless sensor nodes. However, there are two characteristics of these environments that can be used effectively to prevent, detect, and confine attacks: redundancy and continuous adaptation. In this article we propose a global strategy and a system architecture to cope with security issues in AmI applications at different levels. Unlike in previous approaches, we assume an individual wireless node is vulnerable. We present an agent-based architecture with supporting services that is proven to be adequate to detect and confine common attacks. Decisions at different levels are supported by a trust-based framework with good and bad reputation feedback while maintaining resistance to bad-mouthing attacks. We also propose a set of services that can be used to handle identification, authentication, and authorization in intelligent ambients. The resulting approach takes into account practical issues, such as resource limitation, bandwidth optimization, and scalability.
Sexual Health Communication among Youth: A Study of Knowledge and Attitude

Sexual health communication is currently one of the most discussed topic in Malaysia as the country witnessed the surge of sexual related crime and social problem among youths. In relation to this, youths’ knowledge and attitude are the important factor that contribute to this delinquent behaviour and must be addressed as it will shape the youths in the future. The paper discussed the correlation between knowledge and attitude concerning youths in obtaining information on sexual related materials. The research primarily focuses on youths in Malaysia which made up 40% of Malaysia population. The study is significant as it provides a thorough picture how knowledge and attitude influence youths communicate the sexual health topic which is deemed as taboo in Malaysia. The study involved 853 respondents from various demographic group in Malaysia and self-administered questionnaires were distributed and analysed using SPSS to address the research objectives. The result indicated there are significant relationships between knowledge and attitude among youths toward sexual health communication practice. Results showed that 55.1 percent of the studied factors contributed to sexual health communication model among Malaysian youths. Moreover, knowledge and attitude are very critical for the youths to have a better comprehension on sexual health communication. This further testified that Malaysia government and various stakeholders need to acknowledge the importance of sexual health communication and how knowledge and attitude shape positive youth’s development which ultimately contribute to nation building.
Agrarian Impact of Climate Change in Malawi: A Quantile Ricardian Analysis

This paper measures the economic impact of climate on Malawian Agriculture using the theory of Ricardian rents. We use cross-sectional data on climate, hydrological, soil and household level data for a sample of 8,832 households. The results show that climate affects net farm revenue. There is a non-linear relationship between temperature and revenue on one hand and between precipitation and revenue on the other. Estimated marginal impacts suggest that global warming is counter-productive to net farm revenue. The empirical analysis reveals that 2.5°C increase in warming results in predicted losses of US$0.0081 billion and doubling warming to 5°C amplifies the losses to US$0.018 billion. Reducing precipitation by 7% trims net revenue by 8.13% on a per hectare basis. Undoubtedly, 14% reduction in precipitation is predicted to cause reasonably larger losses of about US$0.1161 billion. It can be inferred that this significantly demonstrates Malawi‟s dependence on rain fed agriculture.
