Giving “Best Advice”: Proposing a Framework of Community Pharmacist Professional Judgement Formation
Authors: Roche Cicely , Kelliher Felicity
Published: February 2014

Community pharmacy is often portrayed as a marriage of professional and business roles in a commercial domain, thereby creating a need for, and value in, pursuing the development of professional competencies for use in the community pharmacy business. In context, professional judgement is the application of knowledge, skills and attitudes (competencies) which, when applied to situations where there is no one or obvious right or wrong way to proceed, gives a patient a better likelihood of a favourable outcome than if a lay-person had made the decision. The challenge for community pharmacists is that professional judgement formation is influenced by professional, commercial and personal criteria with inherent interconnected challenges. In community pharmacy practice in the Republic of Ireland (ROI), this challenge is compounded by the fact that advice is normally provided in an environment where the pharmacist provides professional advice “for free” and then may offer to sell the patient a product or service based on that advice, an activity which amounts to a commercial transaction. While there is currently no evidence to confirm whether or not these professional judgement influences are resolved successfully, their very existence poses a risk that their resolution “in the wrong way” could compromise patient outcomes or professional standing following the delivery of pharmacy services. It is therefore apparent that a community pharmacist requires skills in identifying and analysing professional/commercial/personal influences in order to appreciate the criteria which may affect both parties’ (patient and pharmacist) decision making. By contemplating the interaction between the pharmacist’s professional competencies and the individual influences on that pharmacist, we can consider the enhancement of professional competencies that underpin the “best” advice being offered to the patient, regardless of whether that advice is offered in the course of dispensing prescriptions or delivering vaccination or other services, culminating in a framework of professional judgement formation.

Authors: Yu Hua , Zhou Jielin , Deng Licheng , Wen Zhiyu
Published: February 2014

This paper presents a micro-electro-mechanical system (MEMS) piezoelectric power generator array for vibration energy harvesting. A complete design flow of the vibration-based energy harvester using the finite element method (FEM) is proposed. The modal analysis is selected to calculate the resonant frequency of the harvester, and harmonic analysis is performed to investigate the influence of the geometric parameters on the output voltage. Based on simulation results, a MEMS Pb(Zr,Ti)O3 (PZT) cantilever array with an integrated large Si proof mass is designed and fabricated to improve output voltage and power. Test results show that the fabricated generator, with five cantilever beams (with unit dimensions of about 3 × 2.4 × 0.05 mm3) and an individual integrated Si mass dimension of about 8 × 12.4 × 0.5 mm3, produces a output power of 66.75 μW, or a power density of 5.19 μW∙mm−3∙g−2 with an optimal resistive load of 220 kΩ from 5 m/s2 vibration acceleration at its resonant frequency of 234.5 Hz. In view of high internal impedance characteristic of the PZT generator, an efficient autonomous power conditioning circuit, with the function of impedance matching, energy storage and voltage regulation, is then presented, finding that the efficiency of the energy storage is greatly improved and up to 64.95%. The proposed self-supplied energy generator with power conditioning circuit could provide a very promising complete power supply solution for wireless sensor node loads.
Extracellular vesicles from a muscle cell line (C2C12) enhance cell survival and neurite outgrowth of a motor neuron cell line (NSC‐34)
Authors: Madison Roger D. , McGee Christopher , Rawson Renee , Robinson Grant A.
Published: February 2014

Introduction

There is renewed interest in extracellular vesicles over the past decade or 2 after initially being thought of as simple cellular garbage cans to rid cells of unwanted components. Although there has been intense research into the role of extracellular vesicles in the fields of tumour and stem cell biology, the possible role of extracellular vesicles in nerve regeneration is just in its infancy.

Background

When a peripheral nerve is damaged, the communication between spinal cord motor neurons and their target muscles is disrupted and the result can be the loss of coordinated muscle movement. Despite state‐of‐the‐art surgical procedures only approximately 10% of adults will recover full function after peripheral nerve repair. To improve upon such results will require a better understanding of the basic mechanisms that influence axon outgrowth and the interplay between the parent motor neuron and the distal end organ of muscle. It has previously been shown that extracellular vesicles are immunologically tolerated, display targeting ligands on their surface, and can be delivered in vivo to selected cell populations. All of these characteristics suggest that extracellular vesicles could play a significant role in nerve regeneration.

Methods

We have carried out studies using 2 very well characterized cell lines, the C2C12 muscle cell line and the motor neuron cell line NSC‐34 to ask the question: Do extracellular vesicles from muscle influence cell survival and/or neurite outgrowth of motor neurons?

Conclusion

Our results show striking effects of extracellular vesicles derived from the muscle cell line on the motor neuron cell line in terms of neurite outgrowth and survival.

Published: February 2014

A family of chiral ligands derived from α-phenylethylamine and 2-aminobenzophenone were prepared by alkylation of the nitrogen atom. Upon reaction with glycine and a Ni(II) salt, these ligands were transformed into diastereomeric complexes, as a result of the configurational stability of the stereogenic nitrogen atom. Different diastereomeric ratios were observed depending on the substituent R introduced in the starting ligand, and stereochemical assignments were based on X-ray analysis, along with NMR studies and optical rotation measurements.

Published: February 2014

Remote laboratories start to be an important tool both in science and education. The massive spread of those modern technologies is hampered by the absence of the standardized solutions and difficulties with their implementation by the wide segment of scientists and educators. This paper intends to contribute to the idea how the artificial intelligence may contribute to the remote laboratories controlling programme creation and thus remove the ensuing barrier. The paper describes first the basic scheme of a remote experiment on a typical solution example based on the Internet School Experimental System (ISES) hardware and the state of the art in the compiling of the control programme software. Then it focuses on the basic principles of the artificial intelligence and suggests its use in the developing of remote experiments. This part can serve as an inspiring source of ideas for the future developments in the area, particularly in the consideration about the future of remote experiments. In conclusions are summarized the main contributions of the artificial intelligence, which will affect the development of software for the design of control logic of remote experiments, especially based on the system ISES.
A Position Sensitive Clustering Algorithm for VANET
Authors: Liu Haiqing , Yang Licai , Zhang Yao , Wu Lei
Published: February 2014

In order to overcome the defects such as too many cluster heads and large overhead in traditional single hop VANET clustering algorithms when there are high density vehicles, this article proposes a multi-hop cluster algorithm named the position sensitive clustering algorithm (PSCA). Based on the establishment of cluster structure, initial cluster head is selected following the â??Randomly Competition, First Declare Winâ?? principle. Cluster members transmit their expected status messages through the maintained multiple hop routings. After a series of information fusion and calculation work, the cluster head broadcasts the management messages based on dynamic timestamps. This article also gives the cluster maintaining strategy when the cluster head disappears or new nodes join. Tests performed in the simulation by NS-2 show that the proposed algorithm has less cluster heads and lower control overhead compared to the single hop-based approach (the Lowest-ID algorithm).

Authors: Yuan Zhenguo , Zhao Lin
Published: February 2014

The integration of Strap-down Inertial Navigation System (SINS) and Global Positioning System(GPS)can not merely reduce the error of navigation system, which would enhance the system dynamic performance. GPS Carrier phase rate is a high-precision measurement without integer ambiguity problem. Moreover, only one GPS receiver is needed for SINS/GPS carrier phase rate integrated navigation system. The measurement of GPS carrier phase rate is derived and a integrated scheme of SINS and GPS carrier phase rate is proposed. Common used nonlinear filter, extended Kalman filter (EKF) has high-order truncation errors which affects the system accuracy. An improved cubature Kalman filter(CKF) used square root is introduced. The square-root CKF calculate avoids calculating the Jacobian matrix and has better estimate precision.

The Relevance of Science in Development
Authors: Jaffe Klaus
Published: February 2014

Scientific knowledge and technical expertise promote the wealth of nations. The traditional view is that science allows the expansion of technology, which, in turn, promotes economic development. This chapter shows that: 1) the scientific productivity of a country correlates more strongly with gross national income per capita than its technological sophistication; 2) science is important for economic growth among developed economies, whereas technical complexity is more important for the economic development of poorer countries; 3) scientific productivity of countries correlates more strongly with present and future wealth than indices reflecting its financial, social, economic, or technological sophistication; and 4) middle-income countries with higher relative productivity in basic sciences such as physics and chemistry have the highest economic growth in the following five years compared to countries with a higher relative productivity in applied sciences. No simple direct causal relationship between scientific productivity and economic growth could be detected. The results are best explained by assuming that science favors economic development by providing society with a more rational atmosphere, allowing the implementation of sound policies and institutions, and/or that rational societies with successful economic policies are also the ones giving priority to basic natural sciences.
Business Ethics in Emerging Economies
Authors: Windsor Duane
Published: February 2014

This chapter seeks to identify useful game-theoretic insights concerning key issues of business ethics in emerging economies. The study considers four elements in this sequence: game theory, emerging economies, business ethics, and key issues. The chapter does not undertake formal modeling but rather emphasizes useful insights. Game theory provides assistance in reasoning about strategic scenarios for businesses in emerging economies. A multinational entity operates within layers of institutions and norms from international to national and sub-national levels. The approach taken here is to inquire into certain specific decision scenarios available in the extant literature as instances of important classes of decision problems. These scenarios involve long-term sustainable business models, corporate values, and corporate reputation.
Decision-Making in Economics
Authors: Martins Renato Alas , Kumar Kuldeep , Mukherjee Avik , Nabin Munirul H. , Bhattacharya Sukanto
Published: February 2014

In this chapter, the authors consider some of the issues regarding the rational choice decision framework in neoclassical economics and how it can particularly be found wanting in the absence of due consideration for some of the underlying critical neurobiological factors which govern decision making. They develop a critical decision problem and explore the scenario where the solution predicted by formal economic theory may be in conflict with the decision that actually occurs. Such conflict is especially relevant in the context of economic decision making in emerging markets where there can be a lack of trust in the system by the agents operating within it. Based on logically consistent arguments derived from the extant literature, the authors argue that non-consideration of underlying neurobiological factors is a direct cause of this conflict.
Social Capital, the Culture of Trust, and Economic Development
Authors: Cartwright Edward , Singh Thomas
Published: February 2014

The benefits accruing from social networks and structures have been shown to correlate with economic performance at both the macro- and micro-levels. Indeed, social capital can be seen as a catalyst through which human and physical capital are utilized and political and economic freedom realized. In this chapter, the authors briefly review the broad extant literature on social capital before embarking in more detail on how game theory can be used to analyze and model social capital. Particular attention is given to the population game approach. This approach is well suited to model social capital as it allows us to capture individual behaviour, societal influence, and network structure. The growth of social capital is seen to depend on the incentives for cooperation, the way in which people learn from past experience, and the inter-connectedness of the social network. A particularly important question for many emerging economies is how social capital can be encouraged to grow from a low base. In a concluding section, which includes a discussion of the complementarities between strong institutions and social capital, the authors use the population game approach to study this issue.
The Rationality of Dumping
Authors: Garita Mauricio
Published: February 2014

Central America is an interesting region for developing business, and its proximity to South and North America makes the isthmus a strategic region for growth. Guatemala is seen as an emerging economy with the capacity for growth and expansion. The cement industry is now one of the most competitive industries in Central America and has expanded to different countries in the region. However, this was not the case in 1999 when the Mexican Firm Cruz Azul entered via a price predation strategy into the Guatemalan market. Game theory demonstrates the advantage of price predation and the rational decision-making behind the strategy, and also demonstrates that a business smaller than its competitors can win a price predation battle by cooperating. The analysis is based on the dissertation by Garita (2008).

Published: February 2014

The state evaluation of mining electromechanical equipment is important but complicated, for the complexity, nonlinearity and the ambiguity of the influence factors. In this paper, a novel indicator system to assess the state of mining equipment is constructed from three main aspects, namely the product quality of the equipment, their operating conditions and statistic data of historical states. The ambiguity-fuzzy method and grey-sum method are both employed to evaluate different influence factors, and are summed up together as the final evaluation result by dynamic weighting function, which is derived from a modified expert scoring mechanism we propose. We further implement the proposed evaluation system and verify the effectiveness of the evaluation system through real data set based experiments. The experimental results indicate that this system is of important guiding significance to the state evaluation of coal mine equipment and safe production in coal mines.

Authors: Li Xiu Ling , Wang Juan
Published: February 2014

Green high performance fiber reinforced cementitious composites (GHPFRCC) is the optimized mix proportion of engineered cementitious composites (ECC) with high volume of fly ash and polyvinyl alcohol (PVA) fiber. To study the compressive performance, the prism stress-strain relationship of GHPFRCC is the focus in this study. There are sixteen groups of GHPFRCC specimens with the size 40mm×40mm×160mm. The compressive stress-strain curves were obtained based on the uniaxial compression tests. Experimental results show that the uniaxial compression stress-strain curve belongs to the skewed unimodal curve. The peak strain can steadily reach more than 0.005, and it has put up a great plastic deformation capacity and post-peak ductility. It has still reserved some residual strength even when the strain is up to a bigger value. The research achievements can promote the application of GHPFRCC in the practical engineering.

The functionalized silicon carbide (SiC) fillers are employed to fabricate silicon carbide/polyphenylene sulfide (PPS) composites by mechanical ball milling-compression molding method. The thermal conductive coefficient of the SiC/PPS composites with 40 wt% functionalized SiC is 0.934 W/ mK, 4 times higher than that of the original PPS. The mechanical properties of SiC/PPS composites are optimal with 5 wt% addition of SiC. Both the heat resistant and dielectric properties of the SiC/PPS composites are increased with the increasing addition of SiC. For a given SiC loading, the surface functionalization of SiC can improve the thermal conductivities and mechanical properties of the SiC/PPS composites simultaneously.

The objective was to gain the fire characteristics of the External Thermal Insulation Composite Systems (ETICS), which is widely used in China. A series of large-scale fire experiments were conducted under ISO 9705 room test on the ETICS with its core of polystyrene (PS) foam and its outer layer of plastering mortar. The various thicknesses (3 mm and 5 mm) of the outer layer were considered. Under the fire source impact and the melting behavior of PS foam, the flame evolution of ETICS could form a flowing fire and cavity fire, which was obviously different from that of thermal insulation panel itself, but similar to the sandwich panels. A detailed analysis was performed to quantify some major parameters, such as the heat release rate (HRR) and temperature distribution. The results indicated that the peak of HRR could be reduced 11.34% and put off 94 seconds by the thicker outer layer (5 mm); similarly the peak of HRR could be reduced 22% and put off 190 seconds by the flame-retardant treated.

Polypropylene-based composites are prepared using hydrolyzed collagen (HC) from wastes of the leather industry. Blends of polypropylene and HC were studied as a function of the blend composition ratio with the aim of developing a formulation with optimal physical-chemical and mechanical properties. The prepared mixtures were characterized by thermal analyses and mechanical test. Blends with content up to of 20-30% of collagen hydrolizate are susceptible to be melt processed to provide transparent, cohesive and flexible films. In front of positive results the reutilization of collagen hydrolizate derived from the tannery industry appears feasible for production of thermoplastic items for applications in packaging and agricultural segments.
SEM, AFM and LFM Study of the Worn Surface of C/C Composites with Smooth Lamination and Rough Lamination/Resin Carbon Matrixes
Authors: Li Li Ya , Ge Yi Cheng
Published: February 2014

The tribological behavior of C/C composite with smooth lamination (SL) and rough lamination/resin carbon (RL/RC) matrixes was tested using M2000 wear tester and the worn surface morphology was investigated by scanning electron microscopy (SEM), atomic force microscopy (AFM) and Lateral Force Microscopy (LFM) methods. It is found that the worn surface of SL exhibits rough friction film and large worn particles with diameters about 300 nm and with leaning-angles around 30 °. Comparatively, the worn surface of RL/RC achieves smooth friction film and is full of small particles with the grain size about 100 nm and with leaning-angles about 10 °. It is demonstrated that RL/RC exhibits a high density of 1.86 g/cm3, high graphitization degree of 67 %, and extensively low hardness of HRF 42. Those superior properties contribute to the close friction force of different components and excellent tribological behavior.

Authors: Li Li Ya , Ge Yi Cheng
Published: February 2014

We study systematically the morphology and graphitization of the worn surface of C/C composite with rough lamination/smooth lamination/resin carbon (RL/SL/RC) as matrix precursor tested by using M2000 wear tester with a couple of Cr-coated 40 Cr steel. Scanning electron microscopy (SEM) and atomic force microscopy (AFM) analyses indicate that the worn surface of RL/SL/RC is integrated. Particles with the size of 100~300 nm could be found on the worn surface. The leaning-angles of the particles against the sliding direction on the worn surface are between 30 ° and 50 °. Raman laser spectrum (RLS) analysis reveals that, after the wear test, the graphitization on the worn surface of RL/SL/RC decreased with the increase in load, but graphitization of the fiber kept constant and that of the boundary increased up to 150 N. The surface graphitization of different components became closer and closer with the increase in load.

Photocatalytic hydrogen generation holds promise as the future source of environmentally friendly and economically feasible energy source. In order to conduct more efficient photocatalytic reaction, anatase TiO2 doped with transition metals is proposed as catalyst. Investigation was conducted by using density functional theory (DFT) augmented with Hubbard U treatment to correct the band gap of TiO2. Emergence of new states inside the band gap of doped anatase TiO2 can lead to a material with a better photocatalytic property, i.e., able to work at visible light than that of pristine TiO2 which is sensitive to UV light only. The investigated materials comply with standard hydrogen electrode (SHE), thus can be used as photocatalyst in water splitting reaction. Out of the two options tested, TiO2 doped with Fe produces a material with the better photocatalytic properties.Keywords: DFT + U, anatase TiO2, photocatalytic, water splitting, band gap
