Verdi's Don Carlo as Monument
Authors: Vella Francesca 
Published: March 2013

AbstractWhen Verdi's Don Carlo made its debut at La Scala in March 1868, it was hardly the latest operatic news; since its 1867 premiere at the Paris Opéra, it had been widely performed and written about. One aspect of the debates in the Milanese and the Italian press, however, deserves special attention: the depiction of the opera as a ‘monument’. Although the work's astonishing length (compared to that of most of Verdi's previous operas) and the composer's increasing prestige as a national figure might both have been reasons for this impression of monumentality, there were clearly others. The article explores some of these reasons in relation to post-Unification urban renewal, the increasing success of la musica dell'avvenire and the beginning of a slow rediscovery of ‘ancient’ musical works. It argues that Don Carlo was thought of as a monument primarily because it was perceived as standing between the past and the future, and as such was the epitome of contemporary attitudes towards these temporal categories.

Building upon Deci's and Ryan (1985) Self-determination theory as well as the sportive behavioral correlates of the model of Commitment (Scanlan et al., 1976), this study tries to establish the relationship between motivation and commitment in youth sport. For this purpose 454 young competitive soccer players answered the Sport Motivation Scale (SMS) and the Sport Commitment Questionnaire (SCQ) during the regular season.The SMS measures the three dimensions of the Motivational continuum (the Amotivation, the Extrinsic Motivation and the Intrinsic Motivation). The SCQ measures the Sportive Commitment and its composing factors such as the Enjoyment, the Alternatives to the sport, and the Social Pressure. Our findings provided a clear pattern of the influence of motivation in sport enjoyment and commitment, outlining the positive contribution of intrinsic and extrinsic motivation to enjoyment and commitment. Amotivation, contributes positively to alternatives to sport and negatively to enjoyment and commitment. It should be noted that extrinsic motivation has a higher contribution to enjoyment whereas intrinsic motivation has a higher contribution to commitment.
Interindividual Variability in Vocabulary, Sentence Comprehension and Working Memory in the Elderly: Effects of Cognitive Deterioration

Published: March 2013

Interindividual variability in vocabulary, sentence comprehension and working memory is studied in older people with mild cognitive impairment, very low cognitive impairment and normal state, according to the Mini Examen Cognoscitivo (MEC). In the study participated 71 seniors, aged between 62 to 90 years of age, with low instructional level (from one to five years of regular education). Variability measures were calculated in a test of lexical knowledge, another of working memory, and also in one of sentence comprehension.The results obtained using a polynomial regression analysis of the absolute residual scores on the MEC, showed that: (a) variability increases in a linear fashion as the MEC score decreases in the case of nouns, and sentences with one proposition that do not follow the canonical order of constituents in Spanish; (b) Performance on the simpler sentences (one proposition and canonical order) and in the most complex ones (two propositions and non-canonical order) variability showed a change in its trend from MEC scores that indicate cognitive deterioration; (c) In relation to performance on the verbs, variability’s change of trend is not linked to cognitive deterioration. We discuss the results in terms of the utility of these measures as potential indicators of cognitive impairment.
Heterogeneity in the nutrient limitation of different bacterioplankton groups in the Eastern Mediterranean Sea
Authors: Sebastián Marta , Gasol Josep M 
Published: March 2013

Abstract
The heterotrophic bacterial community of the Eastern Mediterranean Sea is believed to be limited by phosphorus (P) availability. This observation assumes that all bacterial groups are equally limited, something that has not been hitherto examined. To test this hypothesis, we performed nutrient addition experiments and investigated the response of probe-identified groups using microautoradiography combined with catalyzed reporter deposition fluorescence in situ hybridization. Our results show contrasting responses between the bacterial groups, with Gammaproteobacteria being the group more affected by P availability. The Roseobacter clade was likely colimited by P and nitrogen (N), whereas Bacteroidetes by P, N and organic carbon (C). In contrast, SAR11 cells were active regardless of the nutrient concentration. These results indicate that there is high heterogeneity in the nutrient limitation of the different components of the bacterioplankton community.
Optimisation of the I–V measurement scan time through dynamic modelling of solar cells
Authors: Herman Matic , Jankovec Marko , Topič Marko 
Published: March 2013

High‐performance solar cells and photovoltaic modules exhibit high internal capacitance, limiting the speed of their transient responses including the current–voltage characteristics scans. This study proffers a model‐based method to obtain optimal scan time during the current–voltage performance characterisation of a solar cell or module while preserving a pre‐set accuracy. Static model parameters are extracted from the quasi‐static current–voltage characteristic, whereas the capacitive character, modelled by two bias voltage dependent capacitances, is determined from the open‐circuit voltage decay measurement. The obtained model is used to calculate the optimal current–voltage curve scan time. Efficacy of the proposed method is demonstrated through test results obtained on three wafer‐based solar cells. I–V curve errors determined by the proposed method at different scan times are in good agreement with the measurements. Results show that in order to achieve < 0.5% error in curve fitting, determined scan times of tested crystalline silicon solar cells lie within the range of 3.6–45 ms for constant angle step semiconductor curve tracer. Use of a capacitive‐based curve tracer, however, requires approximately twice that time to retain a comparable error.
Times‐series modelling for the aggregate Great Britain wind output circa 2030
Authors: Sturt Alexander , Strbac Goran 
Published: March 2013

The authors present a four‐season model representing the aggregate output of a possible British wind fleet circa 2030, suitable for providing synthetic wind time series or a statistical characterisation of the transitional behaviour at timescales of 1 h and above. The model is fitted to an aggregated power output time series derived from historic onshore anemometry data and shown to provide a good fit to both long‐term and transitional statistics. The authors show that the use of a constant factor to extrapolate anemometer‐height wind speeds to hub height leads to an excessive diurnal variation in the implied wind power output. They adjust the model parameters to compensate for this and to account for the offshore component that is not present in the raw data. The complete parameter set is presented.
Impact of wind power on sizing and allocation of reserve requirements
Authors: De Vos Kristof , Morbee Joris , Driesen Johan , Belmans Ronnie 
Published: March 2013

The increasing share of renewable energy sources for electricity, driven by variable output technologies such as wind and solar photovoltaics, is expected to have an impact on the operational reserve requirements of power systems. This study applies a probabilistic approach to estimate reserve requirements and establishes a methodology that makes it possible to distinguish between different categories of reserves based on the imbalance drivers of wind power. The methodology is based on sizing fast‐response reserves based on the distribution of output fluctuations inside the settlement period, and sizing slow‐response reserves based on the distribution of the average prediction error over the settlement period. The main advantage of this methodology is a reduction of the fast‐response reserves, which are generally assessed as expensive compared to slow‐response reserves. This approach is applied in a case study and compared with alternative strategies. The results for 500 MW of wind power installed in a North Sea country confirm these reductions and show that with the suggested approach the required fast‐response and slow‐response reserves, respectively, amount to 7 and 23–26% of the installed wind power capacity.
Fray Felipe Arroyo de la Cuesta’s Work on California’s Native Languages
Authors: Fountain Catherine 
Published: March 2013

SummaryThis article describes the linguistic work of Felipe Arroyo de la Cuesta (1780–1840), a Franciscan missionary from Spain who lived and worked in the missions of Alta California for some 32 years. He was the most prolific chronicler of the indigenous languages of Alta California during the mission period, writing a vocabulary and grammar of the Costanoan/Ohlone language Mutsun, taking notes on a Yokuts language he called Nopthrinthres, and compiling shorter word lists and religious texts in numerous other languages. The present work seeks to bring together and analyze what information is available about Arroyo de la Cuesta’s life and writings and place these within the broader field of missionary linguistics.
Vygotsky, Cognitive Development and Language
Authors: Christy T. Craig 
Published: March 2013

SummaryLev Vygotsky’s (1896–1934) views of the genesis of language and its relation to thought, illustrated here by his account of the origin of the pointing gesture, can be seen as anticipating current research in socially constituted cognition, pragmatics, developmental psychology and grammaticalization, in all of which the importance of contextual and pragmatic factors looms large. His conceptualization of the evolution of communication from action to semiosis has bearing on, and is illuminated by, recent developments in neurobiology, developmental psychology, primatology, and grammaticalization theory. Specifically, recently discovered mirror neuron systems may offer a neurophysiological platform for the evolution of language from gesture and imitation, for the transition from action to sign, from referential to relational meaning, an evolution in which the establishment of joint attention is pivotal. With his emphasis on the dynamic, socially constructed nature of signs, Vygotsky shares Humboldt’s view of language asenergeia, as a system in a perpetual state of emergence, a view consistent with Condillac’s ‘language of action’, in which spontaneous vocalizations and gestures give rise to sign functions. Research of the grammaticalization pathways associated with demonstratives and modal particles also offers new perspectives on the process and hypothesized unidirectionality of grammaticalization, including the plausible claim that demonstratives represent a second and separate source of candidates for grammaticalization. Integrating grammaticalization research with findings from relevant social and natural sciences holds out the prospect of underwriting significant advances in understanding the origin of language and the emergence of grammar.
First Report of Brown Rot on Crataegus pinnatifida var. major Caused by Monilia yunnanensis in China
Authors: Zhao Y. Z. , Wang D. , Liu Z. H. 
Published: March 2013

Crataegus pinnatifida Bge. var. major N. is a time-honored herbal medicine and an important economic fruit that is processed into various foods. Cultivated fields are mostly situated in northern China. In August 2012, a fruit brown rot disease on mature plants was found in Fushun, Liaoning Province, China. This disease reduced the yield and the quality of fruits; the incidence of fruits affected in each tree was between 20% and 35%. The initial stage of infection was marked by regular or irregular light brown spots turning dark brown and gradually supporting many grey fluffy tufts of mycelium. At last, the lesions expanded, causing the fruits to become rotted or withered. The pathogen was isolated from infected fruits by a tissue isolation method (1) and cultured on potato dextrose agar (PDA) at 25°C under 12 h light/12 h dark for 7 days. The colonies reached 60 to 75 mm in diameter after 7 days and were pale green or pale yellow with a neat greyish white margin; the aerial mycelium sometimes formed annulations. The conidia were single, hyaline, lemon-shaped or oval, and 11.3 ± 1.4 (8.0 to 16.5) × 6.4 ± 0.8 (5.1 to 7.6) μm; sporulation was sparse and stromata that formed after 15 days were abundant, black, and spherical to elliptical in shape. Conidiophores were simple or branched, bearing a single conidium on the tip. The internal transcribed spacer (ITS) region of rDNA amplified with primers ITS1 and ITS4 was directly sequenced in both directions. The ITS1-5.8S-ITS2 sequence of rDNA was 100% identical to Monilinia yunnanensis (GenBank Accession No. HQ908788.1), which is distinguished from the closely related M. fructigena (AF150679.1) and M. polystroma (JX315717.1). The pathogen was identified as M. yunnanensis on the basis of morphological characteristics (2) and the ITS sequence of rDNA (2,3). Pathogenicity tests were performed on detached healthy fruits. Four fruits were wounded with a sterilized nail and inoculated by placing a PDA plug of mycelia on upper surfaces of the fruits. Another four fruits treated with sterile PDA plugs served as a control. Fruits were cultured in petri dishes with a 12-h photoperiod at 25°C and 90% relative humidity. The initial symptoms on inoculated fruits were observed after 5 days, while no symptoms showed on the controls. The pathogen was reisolated from the inoculated fruit and identified as M. yunnanensis by the above methods. While M. yunnanensis has been reported to cause brown rot on peach (2), to our knowledge, this is the first report of M. yunnanensis infecting C. pinnatifida Bge. var. major N. in China.

Authors: Corsi Armando Maria , Marinelli Nicola , Alampi Sottini Veronica 
Published: March 2013

PurposeThe paper aims to analyse the current situation and the perspectives of Italian wine in key Asian export markets – China, Japan, India, Singapore and South Korea. These countries show the highest growing rates in wine consumption and are forecasted to become increasingly more strategic for Italian wine producers.Design/methodology/approachA SWOT analysis is applied to the most recent set of secondary data available from the Italian National Institute of Statistics (ISTAT), the Italian National Institute for Foreign Trade (ICE), the International Organisation of Wine and Vine (OIV) and Euromonitor International reports.FindingsThe study reveals that the most interesting markets for Italian wines are China and South Korea. The key strengths are mainly related to high quality products, evoking classic values and being perceived as a status symbol, while the main concerns for Italian wines are mainly related to promotion and distribution issues.Research limitations/implicationsThe SWOT analysis can be used to develop a strategy that takes into consideration the potential strengths and opportunities and the impact of weaknesses and threats, but it cannot cover all the possible aspects Italian wineries must know about Asian markets. It offers a base for further and deeper thoughts about the how to succeed in the most dynamic and challenging markets of the next 20 years.Originality/valueDifferently from other studies, which tend to analyse Italian perspectives in Asian markets on a country‐by‐country basis, this work represents the most recent and comprehensive research on Italian wines in Asian markets.

Published: March 2013

PurposeThe paper seeks to highlight how academic libraries are harnessing widgets to make library resources easily and conveniently accessible to users. Examining the characteristic features, purposes of use and types of widget applications, the paper aims to measure the degree of implementation of widget among academic libraries in different regions.Design/methodology/approachA stratified sampling method was followed for selecting four samples of population, each representing one of the four continents (North America, Europe, Australia and Asia) and content analysis was used to collect data along the checkpoints.FindingsGiving a comparative account of widget implementation along the select dimensions, the study focused on relative acceptance of widgets among the continents and emphasized the areas where widget is being applied most. With examples, the study also illustrated the relevance of the different approaches taken by various libraries.Research limitations/implicationsThe study was confined to selected libraries of higher education institutes among the four continents only. Libraries having non‐English websites and restricted or limited access were not included.Originality/valueThis unique investigation presented a comprehensive picture of widget implementation among the academic libraries across the world. The findings will serve as a valuable guide for future librarians who wish to incorporate such technologies in library websites. Furthermore, the checkpoints used here may serve as a bedrock for framing questionnaire and interview schedule for conducting future research investigating users' perception of this new web‐based tool in order to comprehend fully the practicability and usefulness of widget.

Private bailiffs as partners of the Serbian state
Authors: Planojević Nina 
Published: March 2013

PurposeIn a 2011 law, Serbia included the private sector in enforcement procedures implemented by private bailiffs in addition to those appointed by the court. The purpose of this paper is to determine whether this situation is a form of public‐private partnership. Analyzing the causes of court enforcement crises, this paper establishes whether this step was necessary.Design/methodology/approachIn the development of this paper, normative, sociological, dogmatic and axiological methodologies have been used.FindingsThe introduction of private bailiffs into civil enforcement is a unique public‐private partnership, necessary and justified since it removes all causes of crises in the Serbian system of enforcement.Practical implicationsIt is more likely that Serbian citizens will entrust enforcement to private bailiffs.Social implicationsThis paper contributes to understanding private bailiffs' roles in Serbian society and builds a positive attitude toward this public‐private partnership.Originality/valueIn this paper, public‐private partnership is examined from a new viewpoint and expands cases where the private sector is included from court sanctions. The paper contributes to a better understanding of the institution of private bailiffs, explains its role in the settlement of Serbian enforcement crises and suggests connections between the institution and strengthening the economy.
