Vehicle to grid technology: A review

At present, vehicle to grid (V2G) technology has been received widely attention since a large amount of electric vehicles entering into the market gradually. The electric vehicle (EV) as a specific electricity load, can be used as a mobile storage device to participate load adjusting in the power grid and to provide platform for the renewable energy sources coordination. The management strategies for V2G and the involved key issues are analyzed in details, such as battery weary, bidirectional charger and charging stations via the centralized control, autonomous control and battery management strategies. Besides, the economic benefits from both the power grid & EV owners and research development directions are discussed in the paper.
Continuous improvement and the mini‐company concept

The key issue of continuous improvement (CI) seems to be the problem of combining extensive employee involvement with market orientation and continuation of CI. In this article we review some existing organisational designs for CI on these three essential characteristics of CI. As an alternative to the shortcomings of current organisational designs for CI we present the mini-company concept, related to the sociotechnical concept of the self-managing team. The mini-company concept incorporates the three key issues: it has a self-propelling capacity for CI, involving everyone on the shop floor. A constant and market-oriented source for improvement is found in the clients and suppliers of the mini-company. Results of an in-depth case-study are presented, showing some strong effects of the mini-company concept.
Population Growth, Hysteresis and Development Outcomes in Sub- Saharan African Economies – A Case of Nigeria

This study seeks to investigate if unemployment has been persistence and further examines the effect of population growth on the persistence level of unemployment in Nigeria. Consequent upon these, we trace the impacts that both portends for development outcomes in Nigeria for the period 1970-2012. The technique of analysis is the Auto-Regressive Distributed Lag (ARDL) Bound test for long-run impacts and equilibrium conditions while we re-parametised the model for short-run impact analyses. We found evidence for hysteretic unemployment in Nigeria and that population growth does not play a role in the persistence of unemployment (hysteresis) in Nigeria. More so, our results show that age structure does not matter for development outcomes and that Nigeria is not yet undergoing demographic transition. Interestingly, the results further show that unemployment is a causal factor for population growth. While population growth serves as demographic gift for development outcomes in the short-run, it impacts negatively, albeit negligibly, on development outcomes in the long-run situation. We, therefore, recommend policies and programmes that will improve on the absorptive capacity, engender entrepreneurial abilities and promote prudent economic resources in Nigeria. Keywords: Population, Unemployment, Hysteresis, Fertility, Development, ARDL.
Is There a Golden Rule for the Stochastic Solow Growth Model?

This paper analyzes the dependence of average consumption on the saving rate in a one-sector neoclassical Solow growth model with production shocks and stochastic rates of population growth and depreci-ation where arbitrary ergodic processes are considered. We show that the long-run behavior of the stochastic capital intensity, and hence average consumption along any sample-path, is uniquely determined by a random fixed point which depends continuously on the saving rate. This result enables us to prove the existence of a golden rule saving rate which maximizes average consumption per capita. We also show that the golden rule path is dynamically efficient. The results are illustrated numerically for Cobb-Douglas and CES production function.
Interest-rate volatility and volatility spillovers in emerging Europe

Abstract While many transition economies – particularly those that hope to join the Euro – have seen their economies converge to Europe’s, this process is by no means complete. Considerable macroeconomic volatility persists. This study examines the variability of the short-term nominal interest rates of ten transition economies, finding that eight of them exhibit time-varying volatility that can be modeled as a GARCH or Exponential GARCH process. Incorporating various measures of external volatility into the models, we find that those economies with fixed or managed exchange rates tend to experience more volatility spillovers, particularly from the Eurozone, regardless of the degree of transition. Only Estonia has a fixed exchange rate and remains free of international contagion.
Long-term benefits of exercising on quality of life and fatigue in multiple sclerosis patients with mild disability: a pilot study

Objective: To determine if exercise benefits patients with multiple sclerosis. Design: Randomized controlled trial. Settings: Participants exercised at home and also attended exercise classes held in a hospital physiotherapy gym. Subjects: Thirty patients, diagnosed and independently mobile, were recruited in the Dublin area. Intervention: For three months, classes were held twice-weekly and participants exercised independently once-weekly. The control group was monitored monthly and management remained unchanged. Measurements: Measurements were taken at baseline, three and six months. The Modified Fatigue Impact Scale (MFIS), Multiple Sclerosis Impact Scale-29 (MSIS-29) and Functional Assessment of Multiple Sclerosis (FAMS) were used to measure fatigue and quality of life (QOL). Heart rate (HR) and the Borg's Rating of Perceived Exertion (RPE) were recorded during an incremental exercise test. The change from baseline scores between groups was compared using the Mann—Whitney U-test. Results: Twenty-four participants completed the programme (n = 12 in each group). Based on the change in scores at three months, the exercise group had significantly greater improvements in exercise capacity (HR: —14 [-18.5, -2.5] versus 0.5 [-4, 5.5], P= 0.009), QOL (FAMS: 23 [9.5, 42.5] versus -3.5 [-16, 5], P=0.006) and fatigue (MFIS: -13 [-20, -3] versus 1 [-4, 4.5], P=0.02). At six months, the difference in change scores remained significant for FAMS (19 [14, 31] versus -4.5 [-25, 8], P=0.002) and MFIS (-8.5 [-19.5, -1] versus 0.5 [-2.5, 6.5], P=0.02) only. Conclusions: A three-month exercise programme improved participants' exercise capacity, QOL and fatigue, with the improvements in QOL and fatigue lasting beyond the programme.

A large scale Plasmodium vivax- Saimiri boliviensis trophozoite-schizont transition proteome

Plasmodium vivax is a complex protozoan parasite with over 6,500 genes and stage-specific differential expression. Much of the unique biology of this pathogen remains unknown, including how it modifies and restructures the host reticulocyte. Using a recently published P. vivax reference genome, we report the proteome from two biological replicates of infected Saimiri boliviensis host reticulocytes undergoing transition from the late trophozoite to early schizont stages. Using five database search engines, we identified a total of 2000 P. vivax and 3487 S. boliviensis proteins, making this the most comprehensive P. vivax proteome to date. PlasmoDB GO-term enrichment analysis of proteins identified at least twice by a search engine highlighted core metabolic processes and molecular functions such as glycolysis, translation and protein folding, cell components such as ribosomes, proteasomes and the Golgi apparatus, and a number of vesicle and trafficking related clusters. Database for Annotation, Visualization and Integrated Discovery (DAVID) v6.8 enriched functional annotation clusters of S. boliviensis proteins highlighted vesicle and trafficking-related clusters, elements of the cytoskeleton, oxidative processes and response to oxidative stress, macromolecular complexes such as the proteasome and ribosome, metabolism, translation, and cell death. Host and parasite proteins potentially involved in cell adhesion were also identified. Over 25% of the P. vivax proteins have no functional annotation; this group includes 45 VIR members of the large PIR family. A number of host and pathogen proteins contained highly oxidized or nitrated residues, extending prior trophozoite-enriched stage observations from S. boliviensis infections, and supporting the possibility of oxidative stress in relation to the disease. This proteome significantly expands the size and complexity of the known P. vivax and Saimiri host iRBC proteomes, and provides in-depth data that will be valuable for ongoing research on this parasite’s biology and pathogenesis.
The Inconsistency of Land Values, Land Rents, and Capitalization Formulas

This paper examines relationships that exist between farm income, land values, and capital asset pricing theory. Using two commonly referenced data sets, it is shown that land prices and land rents do not have the same time-series representations, a necessary condition for the simple capital asset pricing theory to hold. This suggests that a fundamental rethinking of the way in which land prices are viewed and modeled is needed. More complex models that allow for rational bubbles, risk aversion, and future shifts in government policy or commodity prices may be required.
Monetary policy and the determination of the interest rate and exchange rate in a small open economy with increasing capital mobility

This paper presents a general model of the determination of the interest rate and the exchange rate which is relevant for a small economy with any degree of capital mobility. The model is tested by using the quarterly data of Korea and Singapore. The emperical results show that in the Korean case changes in money supply affect the interest rate, but do not affect the exchange rate, while in the case of Singapore the domestic interest rate is determined by the foreign interest rate and the expected change in the exchange rate, as well as by changes in the money supply; changes in the money supply also influence the exchange rate. The results imply that the progress of capital liberalization in a small country will alter the transmission mechanism from reliance on the interest rate channel alone to effects arising through both the interest rate and the exchange rate.
Progesterone Receptor Expression Is an Independent Prognosticator in FIGO Stage I Uterine Leiomyosarcoma.

OBJECTIVES To analyze the clinical role of hormone receptors in a large uterine sarcomas series with long-term follow-up. METHODS Protein expression of estrogen receptor (ER) and progesterone receptor (PR) by immunohistochemistry was studied in tissue microarrays from 294 patients diagnosed with uterine sarcoma in Norway from 1970 to 2000 and analyzed for an association with clinicopathologic parameters and outcome. RESULTS ER and PR were detected in 136 of 291 and 184 of 291 tumors (three noninformative cases each), respectively. Expression was unrelated to histology, patient age, tumor diameter, the degree of atypia, the presence of necrosis or vascular invasion, or mitotic counts. ER and PR expression was unrelated to survival in the analysis of the entire cohort. When survival analysis was confined to stage I leiomyosarcoma (n = 147), higher PR score was significantly related to longer overall survival (OS) (P = .042). Clinicopathologic prognosticators in this group were age (P = .041), tumor diameter (P = .001), and mitotic count (P = .007), with a trend for atypia (P = .087). In Cox multivariate analysis, PR score (P = .019), tumor diameter (P = .013), and mitotic count (P = .002) were independent prognosticators of OS. CONCLUSIONS Hormone receptor expression is not informative of outcome in the analysis of uterine sarcomas of all stages and histologic types. PR expression identifies patients with longer survival in stage I leiomyosarcoma.
Pollen competition as a unilateral reproductive barrier between sympatric diploid and tetraploid Chamerion angustifolium

Speciation requires the evolution of barriers to gene exchange between descendant and progenitor populations. Cryptic reproductive barriers in plants arise after pollination but before fertilization as a result of pollen competition and interactions between male gametophytes and female reproductive tissues. We tested for such gametic isolation between the polyploid Chamerion angustifolium and its diploid progenitor by conducting single (diploid or tetraploid) and mixed ploidy (1 : 1 diploid and tetraploid) pollinations on both cytotypes and inferring siring success from paternity analysis and pollen–tube counts. In mixed pollinations, polyploids sired most (79%) of their own seeds as well as those of diploids (61%) (correcting for triploid block, siring success was 70% and 83%, respectively). In single donor pollinations, pollen tubes from tetraploids were more numerous than those from diploids at four different positions in each style and for both diploid and tetraploid pollen recipients. The lack of a pollen donor × recipient interaction indicates that the tetraploid siring advantage is a result of pollen competition rather than pollen–pistil interactions. Such unilateral pollen precedence results in an asymmetrical pattern of isolation, with tetraploids experiencing less gene flow than diploids. It also enhances tetraploid establishment in sympatric populations, by maximizing tetraploid success and simultaneously diminishing that of diploids through the production of inviable triploid offspring.

A 6-stage fully pipelined embedded SRAM is implemented in a 90nm SOI technology. The array uses a conventional 6-transistor memory cell and sense amplifier to achieve the cycle time while minimizing the impact of device variation. A sum-addressed pre-decoder allows partial activation for power savings.
Social capital and technical information flows in the Ghanaian manufacturing sector

Social capital in the form of entrepreneurial networks is found to be a determinant of Ghanaian manufacturing enterprise performance. Entrepreneurs with larger, more diverse sets of contacts have more productive enterprises. Entrepreneurs also benefit from the networking activity of others. There is some evidence that the networks facilitate flows of knowledge between enterprises. A simple theoretical model indicates that where such flows take place, there is a potential for sustained endogenous economic growth. However, in Ghana, the flows are not sufficiently complementary to the enterprises' own knowledge for this potential to be realized. Copyright 2000 by Oxford University Press.
Essays in Behavioral and Experimental Economics

This dissertation consists of three essays which make use of laboratory experiments in order to investigate how procedural or contextual factors impact human behavior. The first essay concerns cooperative behavior in groups formed with quota-based selection rules. Participants are randomly assigned to either an orange or a purple group. In the quota treatment, orange participants are chosen as members of a selected group by performance in a simple unrelated math task whereas purple participants are chosen based solely on the quota. The results show significantly less cooperation (measured as behavior in a public good game) in the quota treatment compared to a control treatment where all participants are treated symmetrically. Furthermore, this tendency is observed in both the orange and the purple participants, and regardless of the color of the matched player. The second essay describes the results of a Prisoner’s Dilemma experiment were we document that behavior is more cooperative when the game is called the Community Game than when it is called the Stock Market Game. However, the difference vanishes when only one of the subjects is in control of her action. The social framing effect also vanishes when the game is played se-
Dominant TRPV4 mutations in nonlethal and lethal metatropic dysplasia

Metatropic dysplasia is a clinical heterogeneous skeletal dysplasia characterized by short extremities, a short trunk with progressive kyphoscoliosis, and craniofacial abnormalities that include a prominent forehead, midface hypoplasia, and a squared‐off jaw. Dominant mutations in the gene encoding TRPV4, a calcium permeable ion channel, were identified all 10 of a series of metatropic dysplasia cases, ranging in severity from mild to perinatal lethal. These data demonstrate that the lethal form of the disorder is dominantly inherited and suggest locus homogeneity in the disease. Electrophysiological studies demonstrated that the mutations activate the channel, indicating that the mechanism of disease may result from increased calcium in chondrocytes. Histological studies in two cases of lethal metatropic dysplasia revealed markedly disrupted endochondral ossification, with reduced numbers of hypertrophic chondrocytes and presence of islands of cartilage within the zone of primary mineralization. These data suggest that altered chondrocyte differentiation in the growth plate leads to the clinical findings in metatropic dysplasia. © 2010 Wiley‐Liss, Inc.
Reputation in Online Auctions: The Market for Trust

Online markets have dramatically altered the retail landscape. By eliminating barriers associated with geography as well as the physical costs of maintaining a storefront, online markets have created a "democracy" of buyers and sellers. However, the fluidity of this marketplace and the relative anonymity of transactions has made the problem of maintaining trust critically important. Solving the "trust problem" represents a key competitive advantage for many of the successful players in the online space. For instance, much of the remarkable success of eBay has stemmed from its ability to create valuable and informative reputations for its users through its feedback system. The lock-in associated with a user's reputation on eBay helped it to stave off challenges by Amazon and Yahoo. This article describes how eBay's solution to the ''trust problem," has led to the creation of a "market for feedback" whose sole purpose is the "manufacture" of reputation for eBay users. It presents a case study and a statistical analysis of this market in order to show that its maintenance represents a crucial challenge to eBay's future competitive advantage and, more generally, to solving the "trust problem" in other online markets.
When Less Is More: Distinguishing between Entrepreneurial Choice and Performance

This paper uses NCDS data on individual characteristics to distinguish determinants of entrepreneurial choice, income and job generation. A new model of utility from self‐employment shows that relaxing liquidity constraints could inhibit performance. Empirically, we find that a range of inheritance enhances the performance of the self‐employed and increases self‐employment; while higher education also increases self‐employment income and job creation, but reduces the probability of self‐employment. Combining these choice and performance effects, we find that education has a positive net effect on job creation, as does inheritance up to a certain threshold.
Reproducibility of measurements of regional myocardial blood flow in a model of coronary artery disease: Comparison of H215O and 13NH3 PET techniques.

UNLABELLED PET absolute myocardial blood flow (MBF) with H(2)15O and 13NH3 are widely used in clinical and research settings. However, their reproducibility with a 16-myocardial segment model has not been examined in chronic coronary artery disease (CAD). We examined the short-term reproducibility of PET H(2)15O MBF and PET 13NH3 MBF in an animal model of chronic CAD. METHODS Twelve swine (mean weight +/- SD, 38 +/- 5 kg) underwent percutaneous placement of a copper stent in the mid circumflex coronary artery, resulting in an intense inflammatory fibrotic reaction with luminal stenosis at 4 wk. Each animal underwent repeated resting MBF measurements by PET H(2)15O and PET 13NH3. Attenuation-corrected images were analyzed using commercial software to yield absolute MBF (mL/min/g) in 16 myocardial segments. MBF was also normalized to the rate.pressure product (RPP). RESULTS By Bland-Altman reproducibility plots, the mean difference was 0.01 +/- 0.18 mL/min/g and 0.01 +/- 0.11 mL/min/g, with confidence limits of +/-0.36 and +/-0.22 mL/min/g for uncorrected regional PET H(2)15O MBF and for uncorrected regional PET 13NH3 MBF, respectively. The repeatability coefficient ranged from 0.09 to 0.43 mL/min/g for H(2)15O and from 0.09 to 0.18 mL/min/g for 13NH3 regional MBF. RPP correction did not improve reproducibility for either PET H(2)15O or PET 13NH3 MBF. The mean difference in PET H(2)15O MBF was 0.03 +/- 0.14 mL/min/g and 0.02 +/- 0.19 mL/min/g for infarcted and remote regions, respectively, and in PET 13NH3 MBF was 0.03 +/- 0.11 mL/min/g and 0.00 +/- 0.09 mL/min/g for infarcted and remote regions, respectively. CONCLUSION PET H(2)15O and PET 13NH3 resting MBF showed excellent reproducibility in a closed-chest animal model of chronic CAD. Resting PET 13NH3 MBF was more reproducible than resting PET H(2)15O MBF. A high level of reproducibility was maintained in areas of lower flow with infarction for both isotopes.
Farmers online: drivers and impediments in adoption of Internet in UK agricultural businesses

Farm businesses appear to have much to gain from the use of Internet technology, particularly given their spatial dispersion and typically small scale (in terms of employment and turnover), but available statistics show a lower rate of adoption than small to medium‐sized enterprises (SMEs) in general, with less than one‐third of UK farmers using the Internet for business purposes. This article reports on an investigation by the University of Plymouth of Internet adoption by farmers in two contrasting agricultural areas, with three iterations over six years. Insights will be of value to anyone interested in the adoption of information and communication technology in microbusiness, and/or in the development of e‐commerce in the farm sector. Identifies research and policy issues outstanding in the field of Internet adoption in agriculture, including the rollout of broadband infrastructure, the development of human capital, the key role of farm family members, and the understanding of the complexity underlying the adoption process.
