The Imperative of Service in the Professor's Role.

In the professorial role's traditional triad of teaching, research, and service, research (publishing) and teaching get more attention than service. If professors are to be part of improving education in America's schools, they must define service more broadly, and they must give greater attention to the service role. Education should be conceptualized as a profession of practice, and it should be a profession that embodies its practice in a statement of professional ethics and behavior. Real educational improvement will come only when educators use what is known (the knowledge base for teaching), evaluate it carefully, extend it, and continue a research agenda built on education issues. Education administration (EDAD) professors should teach research results from education research and can influence the technical core of education. Professors have a major service role to play in improving education and in making sure that improvement rests on what research has shown to be effective. They also have a major service role to play in helping shape public opinion about education. Once research has developed a reasonably sound knowledge base for education, a concerted national leadership needs to advocate that these advances be implemented. Professorial service roles linked to this advocacy include: (1) conducting policy research; (2) assisting in local applications of the knowledge base; (3) publishing nonresearch as service; (4) giving attention to what does not work and what does work to help guide practitioners; and (5) exerting leadership for strong moral standards. Three appendixes discuss problem formulation, key elements of business and education, and an example of the potential of education for malpractice. An attachment presents a group activity related to education malpractice. (Contains 2 tables and 17 references.)

The low complexity deterministic SMC detection algorithm for MIMO system

This paper presents a low complexity deterministic sequential Monte Carlo (DSMC) detection scheme, called multi-level mapping DSMC detector, for high-order QAM constellations. The new scheme utilizes the property of QAM constellation and performs the sequence weight calculation in steps of two bits, which reduces the complexity. Being soft-input soft-output in nature, the multi-level mapping DSMC detector can be employed as the first-stage demodulator in a turbo receiver in coded MIMO systems. As a suboptimum detector with complexity linear in the number of transmit antennas, the multilevel mapping DSMC detector provides performance practically identical with that of the basic DSMC detector, and reduces the complexity from exponential in the modulation coefficient to linear with the modulation coefficient. Computer simulation for the uncoded MIMO system in the flat fading channel and the coded MIMO-OFDM turbo receiver system in the frequency selective multi-path fading channel proves the performance.
Modeling of temperature effect on threshold voltage of ballistic Ge tunneling FET

The effect of temperature and scaling of gate length on the threshold voltage of double gate Ge tunneling FET has been studied. The threshold voltage has been determined from transconductance rather than constant current method. In the 10 nm to 50 nm range scaling has almost no effect on threshold voltage. However, threshold voltage is function of temperature in the range of 250–500 K. Besides, a simple model for threshold voltage incorporating the temperature effect has been developed for ballistic Ge tunneling FET based on the simulated results.
Comparison of the Emit immunoassay with HPLC for therapeutic drug monitoring of mycophenolic acid in pediatric renal-transplant recipients on mycophenolate mofetil therapy.

BACKGROUND HPLC is currently the preferred method for accurate measurement of mycophenolic acid (MPA). This study was designed to validate the Emit compared with HPLC in relation to clinical outcome measurements. METHODS Pediatric renal-transplant recipients (n = 50) on an immunosuppressive triple regimen consisting of cyclosporin A, prednisone, and mycophenolate mofetil (600 mg/m(2) twice per day) were investigated in an open-label prospective study. Pharmacokinetic profiles over 12 h were obtained at 1 week, 3 weeks, 3 months, and 6 months posttransplant. Plasma MPA was measured by both reversed-phase HPLC and the Emit immunoassay. RESULTS There was an association between the risk of acute rejection episodes and low area under the curve values from t(0) to t(12h) (AUC(0-12)) for MPA (MPA-AUC(0-12)) or predose concentrations of MPA derived from both HPLC and Emit measurements. According to ROC analysis, an AUC value of 33.8 mg x h/L for MPA from t(0) to t(12h) (MPA-AUC(0-12)) determined by HPLC had a diagnostic sensitivity of 80% and a diagnostic specificity of 57%. The corresponding value of the Emit was 36.1 mg x h/L. For the predose concentration (MPA-c(12)), a concentration of 1.2 mg/L determined by HPLC and 1.4 mg/L determined by Emit gave a sensitivity of 80% and a specificity of 60%, respectively. There was no association of any pharmacokinetic variables derived from total MPA measurements with an increased risk of side effects related to mycophenolate mofetil. CONCLUSIONS The Emit assay appears to have a comparable diagnostic efficacy to HPLC for assessing the risk of acute rejection in pediatric renal-transplant recipients. However, because of the cross-reactivity of the antibody used in the Emit assay with the active MPA acyl glucuronide metabolite, the decision thresholds for the Emit were higher than those calculated from HPLC measurements.
Multi Topic Distribution Model for Topic Discovery in Twitter

Micro logging websites, like Twitter, as a new social media form are growing increasingly popular. Compared with the traditional medias, such as New York Times, tweets are structured data form and with shorter length. Although traditional topic modeling algorithms have been studied well, few algorithms are specially designed to mine Twitter data according to its own features. In this paper, according to the structure of Twitter data, we introduce Multi Topic Distribution Model to mine topics. In addition, we have observed that one tweet mostly discusses either public issues or personal lives. Former studies equally analyze all tweets and fail to discover interests of each individual. With the help of features of Twitter data, dividing topics into two types in semantics, our model not only efficiently discover topics, but also is able to indicate which topics are interested by an user and which topics are hot issues of the Twitter community. Through Gibbs sampling for approximate inference, the experiments are conducted in the TREC2011 data set. Experimental results on the data set have shown an comparison between our model and Latent Dirichlet Allocation, Author Topic Model. We also illustrate an example of topics which are interested by the whole community and several users.
Returns Policy and Quality Risk in E-Business

In this paper, we investigate the interplay between the returns policy, the pricing strategy, and the quality risk. We define quality risk as the possibility of product misfit, defect, or unconformity with the consumers' perception. These notions of quality risks differ in return policy restriction, residual values, and whether it is possible to unambiguously reduce the probability of mismatch. Using a stylized two-segment market setting, we demonstrate that consumer returns are offered only when the high-segment consumers incur a higher hassle cost, and both the quality risk and the valuation of the low segment are moderate. Moreover, it is possible to wisely design the returns policy that eliminates all inappropriate returns. Furthermore, the seller with a high quality risk may offer a refund that exceeds the selling price, which provides a theoretical ground and specific operating regime for the satisfaction guaranteed policy used in some e-tailers. On the other hand, when the quality risk is relatively low, further improvement on mitigating the quality risk may not necessarily benefit the seller. Finally, we observe that the restocking fee may be non-monotonic in product quality; thus, a more generous returns policy does not necessarily indicate a lower quality risk.
Green Market Geography: The Spatial Clustering of Hybrid Vehicles and LEED Registered Buildings

Abstract This paper uses zip code level data to investigate the spatial distribution of two major "green" products. Using data from California, we document where hybrid vehicles cluster within the state. Using data for the entire nation, we study where LEED registered buildings cluster. By creating a novel measure of community environmentalism based on revealed preference political data, we document that green products cluster in environmentalist communities.
Removal of Heavy Metal Ions with Acid Activated Carbons Derived from Oil Palm and Coconut Shells

In this work, batch adsorption experiments were carried out to investigate the suitability of prepared acid activated carbons in removing heavy metal ions such as nickel(II), lead(II) and chromium(VI). Acid activated carbons were obtained from oil palm and coconut shells using phosphoric acid under similar activation process while the differences lie either in impregnation condition or in both pretreatment and impregnation conditions. Prepared activated carbons were modified by dispersing hydrated iron oxide. The adsorption equilibrium data for nickel(II) and lead(II) were obtained from adsorption by the prepared and commercial activated carbons. Langmuir and Freundlich models fit the data well. Prepared activated carbons showed higher adsorption capacity for nickel(II) and lead(II). The removal of chromium(VI) was studied by the prepared acid activated, modified and commercial activated carbons at different pH. The isotherms studies reveal that the prepared activated carbon performs better in low concentration region while the commercial ones in the high concentration region. Thus, a complete adsorption is expected in low concentration by the prepared activated carbon. The kinetics data for Ni(II), Pb(II) and Cr(VI) by the best selected activated carbon fitted very well to the pseudo-second-order kinetic model.
Limbitis Secondary to Autologous Serum Eye Drops in a Patient with Atopic Keratoconjunctivitis

Purpose. Report a case of limbitis secondary to autologous serum eye drops in a patient with atopic keratoconjunctivitis. Design. Interventional case report. Methods. A 32-year-old African American female with atopic keratoconjunctivitis (AKC) presented with chronic dry eye and diffuse punctate epithelial erosions refractory to conservative treatment. She was initially managed with cyclosporine ophthalmic 0.05% in addition to preservative-free artificial tears and olopatadine hydrochloride 0.2% for 6 months. She was later placed on autologous serum eye drops (ASEDs) and 4 weeks into treatment developed unilateral limbitis. The limbitis resolved shortly after stopping ASEDs in that eye; however, the drops were continued in the contralateral eye, which subsequently developed limbitis within 2 weeks. ASEDs were discontinued in both eyes, and the patient has remained quiet ever since. Results. Patient with a history of AKC and no prior history of limbitis developed limbitis shortly after starting ASEDs, which resolved promptly after discontinuation of therapy with no subsequent recurrence of inflammation. Conclusion. ASEDs are widely used in the treatment of complicated or treatment refractory dry eye. The potential side effects should be kept in mind when prescribing ASEDs for any patient, especially in those with underlying immunological diseases and circulating inflammatory factors.
Technological Differences and the Impact of Trade on Wages

We introduce technological differences in a Heckscher-Ohlin model and study how the technology and endowment differences interact to determine the effects of trade on factor prices. When the endowment effect is dominant in determining the autarky relative factor prices, the relative factor prices of trading countries adjust in converging directions with trade if and only if the capital-rich country has a comparative advantage in the capital-intensive sector. Adjustments in converging directions could be excessive. Relative factor prices tend to converge if the technological comparative advantage is small for given relative endowments or if the relative endowment difference is large for a given technological comparative advantage.
A családtámogatások alakulása: célok és eszközök

The paper follows the changes in the support system of the Hungarian family policy from the political transformation up to now. The system of the family assistance significantly changed under almost every government. These changes were caused not only by the different macroeconomic conditions and financial possibilities of the successive governments but by different ideologies and aims of the social policies. The authors show the different principles behind the forms of support, the main types of the family assistance and the concrete means of support belonging to the different types of assistance. They follow up the changing proportion of the expenses of the family assistance compared to the expenses of the budget from 1990 onwards and deal with the most important changes of the concrete forms of assistance. Finally, the paper
Bridging the Divide between Neuroprosthetic Design, Tissue Engineering and Neurobiology

Neuroprosthetic devices have made a major impact in the treatment of a variety of disorders such as paralysis and stroke. However, a major impediment in the advancement of this technology is the challenge of maintaining device performance during chronic implantation (months to years) due to complex intrinsic host responses such as gliosis or glial scarring. The objective of this review is to bring together research communities in neurobiology, tissue engineering, and neuroprosthetics to address the major obstacles encountered in the translation of neuroprosthetics technology into long-term clinical use. This article draws connections between specific challenges faced by current neuroprosthetics technology and recent advances in the areas of nerve tissue engineering and neurobiology. Within the context of the device–nervous system interface and central nervous system implants, areas of synergistic opportunity are discussed, including platforms to present cells with multiple cues, controlled delivery of bioactive factors, three-dimensional constructs and in vitro models of gliosis and brain injury, nerve regeneration strategies, and neural stem/progenitor cell biology. Finally, recent insights gained from the fields of developmental neurobiology and cancer biology are discussed as examples of exciting new biological knowledge that may provide fresh inspiration toward novel technologies to address the complexities associated with long-term neuroprosthetic device performance.
Information security culture: A definition and a literature review

Information security culture guides how things are done in organization in regard to information security, with the aim of protecting the information assets and influencing employees' security behavior. In this paper, we review key literature on information security culture that was published in the period during 2003-2013. The objective was to identify the frameworks that were proposed to establish and maintain information security culture inside organizations. Moreover, other issues were investigated, such as the appropriate definition, and methodology used in this field of research. The review identified 62 papers that were published in that period (2003-2013) were focused on information security culture in organizations as a main topic of that paper. The review draws the attention to the importance of the information security culture and the need for more investigation in the field to provide a comprehensive framework of the establishment of information security culture within organization.
Fiscal Performance and Income Inequality: Are Unequal Societies More Deficit‐Prone?

Summary for non-specialistsA bias towards running deficits is an entrenched feature of fiscal policy making in most developed economies.Our paper examines whether this tendency is in any way associated with the personal distribution of income of a country. It takes inspiration from theoretical work according to which distributional conflicts may give rise to deficit spending or to delayed fiscal adjustment. Although these theories have been around for years the empirical literature on the determinants of fiscal performance has so far paid little or no attention to the possible role played by different degrees of income inequality.Our results suggest that this neglect was not justified. Using cross-country data we find evidence that a more unequal distribution of income can weigh on a country's fiscal performance. These findings can be relevant in the aftermath of the post-2007 global financial and economic crisis in particular when designing fiscal exist strategies. The success and sustainability of such strategies may inter alia depend on their distributional implications.
In-orbit estimation of inertia parameters of target satellite after capturing the tracking satellite

After capturing the tracking satellite, the target satellite will turn into a compound satellite, and the inertia parameters of target satellite can produce great changes and greatly affect the attitude control system and its control effect. In order to estimate the inertia parameters of target satellite, two methods including the method based on Angular Momentum Conservation Law and the modified method based on Angular Momentum Conservation Law are proposed. Comparisons are made with the least-square method. Simulation results show that the inertia parameters of compound satellite can be estimated directly within 200s, so the inertia parameters of target satellite can also be estimated. Compared with the once least-square method, the estimation precision of methods based on Angular Momentum Conservation and modified Angular Momentum Conservation Law are higher. But the product of inertia precision of the modified method is the highest of the three. Basically, it can meet the needs of the inertial parameters estimation of target satellite.
Thermal And Chemical Pre-Treatments Of Cow Dung And Poultry Litter Enhance Biogas Production In Batch Fermentation

Low degradability of substrates is one of the factors that hinder the production of biogas. With the aim of maximizing biogas yields from cow dung (CD) and poultry litter (PL), a series of experiments were carried out under mesophilic conditions at 38 oC using batch digester operating for 21 days hydraulic retention time (HRT). Temperature pre-treatment at 60 and 80 oC and chemical pre-treatment with NaOH (0.45 g, 1.35 g and 2.25 g) were applied as a pre-treatment. Cumulative biogas production and VS reduction from anaerobic digestion of 80 oC pre-treated substrate was 46.3% and 26.1% higher than the control, respectively. However, thermal pre-treatment at 60 and 80 oC did not show statistically significant difference in biogas production. Biogas yields of substrates that received 0.45 g, 1.35 g, and 2.25 g of NaOH increased biogas production by 0.03%, 21% and 56% over that of the control, respectively. Overall results indicated that the biogas yield and VS and TS reduction can be enhanced through thermal and chemical pretreatments prior to anaerobic digestion.
Urban pixels: painting the city with light

Urban environments are increasingly filled with digital display systems that are inflexible, flat, bounded, high-resolution, and unresponsive. In this paper, we explore the potential of physically instantiated pixels that enable flexible, reconfigurable, unbounded, low-resolution, and responsive urban displays. Urban Pixels are nodes in a wireless network of physical pixels for urban spaces. Each pixel unit includes a microcontroller, RF transceiver (433 MHz), LED module (ten bright, white LEDs), rechargeable Li-Ion battery pack, IR sensor and renewable energy source such as photo-voltaic cells. Two acrylic half-spheres (4-inch diameter) protect the components from the elements. No additional wiring is needed for communication and the units can be mounted individually to any surface. A small-scale prototype network of fifty Urban Pixels was displayed on a façade of Eden Court Theater in Inverness, Scotland from June 1 - June 7, 2008. The public was encouraged to change display patterns via SMS or to interact with individual units via flashlights. We observed and informally interviewed theater guests and passers-by interacting with the façade for several nights. Based on these results, we outline an exciting problem space for designing displays and lighting systems in cities.
Topological Z(n + 1) charges on fuzzy sphere

We study the topological properties of fuzzy sphere. We show that the topological charge is only defined modulo N+1, that is finite integer quotient Z_{N+1}, where N is a cut-off spin of fuzzy sphere. This periodic structure on topological charges is shown based on the boson realizations of SU(2) algebra, Schwinger vs. Holstein-Primakoff. We argue that this result can have a natural K-theory interpretation and the topological charges on fuzzy sphere can be classified by the twisted K-theory. We also outline how solitons on fuzzy sphere can realize D-brane solitons in the presence of Neveu-Schwarz fivebranes proposed by Harvey and Moore.
From time series to complex networks: The visibility graph

In this work we present a simple and fast computational method, the visibility algorithm, that converts a time series into a graph. The constructed graph inherits several properties of the series in its structure. Thereby, periodic series convert into regular graphs, and random series do so into random graphs. Moreover, fractal series convert into scale-free networks, enhancing the fact that power law degree distributions are related to fractality, something highly discussed recently. Some remarkable examples and analytical tools are outlined to test the method's reliability. Many different measures, recently developed in the complex network theory, could by means of this new approach characterize time series from a new point of view.
