Stock assessment of the bluemouth (Helicolenus dactylopterus) in Azorean waters during the 1990-2002 period, applying a biomass dynamic model

Evaluación de bocanegra (Helicolenus dactylopterus) en aguas de las Azores durante el período 1990-2002, por medio de un Modelo de Dinámica de Biomasa. Bocanegra es un pez bentónico, que habita principalmente entre los 500 m y 600 m de profundidad. Este recurso es muy importante económicamente para las comunidades de pescadores de las Islas Azores. Las capturas aumentaron desde 1990 hasta 1994 para posteriormente disminuir, obteniéndose el valor más bajo en 1999. La captura por unidad de esfuerzo estandarizada (CPUE) fue empleada como un índice de abundancia relativa; este índice de CPUE se obtuvo usando un Modelo Lineal General que incluyó varios factores: tipo de embarcación, año, mes y tamaño del barco. Los últimos tres factores resultaron ser estadísticamente significativos. Para la evaluación de bocanegra se usó una versión discreta del Modelo de Dinámica de Biomasa de Schaefer y los parámetros fueron estimados usando la serie de CPUE estandarizada para la calibración. Un análisis de riesgo usando simulación de Monte Carlo se llevó a cabo para estimar las probabilidades de que la biomasa a principios de 2003 se ubicara por debajo de la biomasa a principios de 2002, una vez extraída una captura dada. Este análisis determinó, suponiendo un criterio precautorio y teniendo en cuenta que el recurso podría estar en una situación desfavorable (0,19< B2002/Bopt <1,55, con una probabilidad del 95%), que la captura para 2003 no debería superar las 250 t, que corresponde a una probabilidad del 10% de que se genere una disminución de la biomasa a principios de 2003. Complementariamente, como otro indicativo del estado del recurso se analizó la distribución de tallas en los desembarques. Este análisis mostró una tendencia decreciente de la talla media, principalmente para capturas provenientes de regiones donde fueron encontradas las concentraciones más altas (profundidades mayores a 300 m). Se recomiendan evaluaciones anuales futuras para poner al día las estimaciones y el diagnóstico del estado del recurso de bocanegra.
The MinK Framework: Developing Metrics for the Measurement of Individual Knowledge

Knowledge is the currency of the current economy and a vital resource for the sustainability of performance quality in today’s knowledge intensive business environment. To avoid the detrimental consequences of knowledge loss, managers are urged to identify where knowledge stocks exist and how knowledge flows within their organisations by keying out wellsprings of knowledge among their employees. Although some studies have attempted to measure knowledge on an organisational level using different methods, very few studies have addressed the individual knowledge carrier. Moving from a critical literature review of the existing approaches to knowledge measurement, this paper proposes a novel framework that enables organisations to measure individual knowledge in a business context using a set of metrics. The metrics are subsequently validated through a series of in-depth interviews with senior managers.A summary of the managers’ views on individual knowledge measurement is presented. Reflections regarding the industry application and recommendations for the proposed framework are also discussed.
A FRACTIONAL STEPS METHOD FOR SCALAR CONSERVATION LAWS WITHOUT THE CFL CONDITION

We present a numerical method for the n-dimensional initial value problem for the scalar conservation law u(xt, . ,xn,t)t + L:i=1 /;(u)x; = 0, u(xl, . ,xn,O) = ua(xt, . ,xn)· Our method is based on the use of dimensional splitting and Dafermos' method to solve the one dimensional equations. This method is unconditionally stable in the sense that the time-step is not limited by the space discretization. Furthermore we show that this method produces a sub-sequence which converges to the weak entropy solution as both the time and space discretization go to zero. 0. Introduction. Scalar conservation laws have, due to their wide range of applications, been studied extensively over the years, both from a mathematical, physical and numerical point of view. Fundamental problems are the emergence of discontinuous solutions of the partial differential equation with the subsequent call for weak solutions, which again results in subtle uniqueness questions. Existence and uniqueness was first proved for the general Cauchy problem by Conway and Smoller [1], and later on by Kuznetsov [8], Volpert [9], Kruzkov [7] who used a viscocity 1980 Mathematics Subject Classification {1985 Revision). 35165, 65M12, 65M99.
The impact of cyber dating abuse on self-esteem: The mediating role of emotional distress

This study examined how emotional distress mediated the relationship between cyber dating abuse and self-esteem. Participants were 155 undergraduate students (105 females; 50 males) ranging from 17 to 25 years old ( M = 19.38, SD = 1.65) with dating experience and a minimum relationship duration of 3 months. Self-report assessments of cyber dating abuse, self-esteem, and emotional distress from the relationship were completed. Mediation analysis using multiple regressions revealed a full mediation model. Cyber dating abuse predicted lowered self-esteem and greater emotional distress. However, when emotional distress was entered as a predictor of self-esteem, cyber dating abuse became non-significant, indicating full mediation. Early-onset of dating was also a risk factor for cyber dating abuse and emotional distress. Few gender differences were evident. These findings add to the growing body of evidence on the negative effects of cyber dating abuse and suggest that distressing emotional reactions may underlie the deleterious consequences of this form of abuse.
Exploiting subsequence matching in Recommender Systems

Since their inception in the early 1990s, recommender systems have experienced exponential growth as they are being used in a large number of applications because of their usefulness in helping users choose items based on their tastes and needs. Nowadays, they are indispensable in many companies that offer their service through the Internet, the most important method for information exchange. For this reason, continuous innovation in these systems is essential to make recommendations that are able to continue surprising users, while improving the existing ones. In this Master’s Thesis, we have studied and researched on the current state of these systems, paying special attention to collaborative filtering based on neighborhood and content-based algorithms. However, due to the disadvantages that each system may have separately, combinations of these systems are often used in real applications, creating hybrid recommenders. To support this study, we propose the use of the longest common subsequence (LCS) algorithm as a novel aspect to be used as a similarity metric between users, also introducing a general and transparent technique to generate sequences using both content and collaborative information, allowing us to generate hybrid recommenders in a simple way. Complementing these new recommendations, we also detail other auxiliary parameters (confidence, preference, normalization functions, and different orderings), whose main goal is to improve the performance of these LCS-based systems. On the other hand, in addition to the definition of these new recommenders, the study is complemented with experimental results using three well-known datasets in the area: Movielens, Lastfm and MovieTweetings. Each one of them will be oriented to exploit a specific aspect of the sequence generation process. The results have been obtained by using ranking metrics (Precision, Recall, MAP, or nDCG) and novelty and diversity metrics (α-nDCG, EPC, EPD, Aggregate diversity, EILD, and Gini). With these experiments, we aimed at comparing the performance of recommenders based on the longest common subsequence against other well-known recommenders in the area. As a summary, we have observed in the experiments performed that the proposed recommenders are highly competitive, and sometimes they are even better than other recommenders known in the area, both in terms of ranking quality metrics, and novelty and diversity dimensions. However, we have also observed that, in some cases, the use of hybrid recommenders based on the longest common subsequence results in worse performance than other purely collaborative versions. In any case, we believe this is a proposal with enough potential to be worthy of further investigation.
An empirical study on customer profitability accounting, customer orientation and business unit performance

Customer relationship management (CRM) literature argues that to enhance corporate profitability marketing and sales emphasis should foremost be directed to the most profitable customers. Today, however, we have little empirical evidence on how organizations assess customer profitability, and what are the performance implications of customer profitability assessment. Furthermore, it would be interesting to learn how the role and depth of CRM orientation in corporate strategy and operations affect the use of customer profitability analyses. This study aims to explain whether an organization's CRM-orientation has an impact on the form and use of customer profitability accounting. We examine the relation between a company's CRM orientation, customer profitability accounting practices and business unit economic performance. Data from a recent survey (564 respondents, response rate 22%) conducted in Finland are used for our empirical investigation. Our results suggest that an organization's CRM orientation has a direct impact on performance, as well as on the customer profitability accounting practices. The use of customer profitability accounting practices moderates the relationship between the organization's CRM orientation and economic performance. The results give support to the theory that the use of sophisticated customer profitability analysis embedded within an organization's customer profitability accounting practices supports companies' efforts to improve their performance with CRM.
Character displacement under influence of Bergmann's rule in Cerdocyon thous (Mammalia: Canidae)

In South America, the crab-eating fox Cerdocyon thous occurs in sympatry to the ecologically similar, and phylogenetically close Lycalopex vetulus to the North, and Lycalopex gymnocercus to the South of its range. We studied character displacement in Cerdocyon under the effect of Bergmann's rule and the presence (or absence either) of Lycalopex within the crab-eating fox range. We performed skull shape analysis on 191 C. thous specimens and divided them in three distinct groups, depending on whether Cerdocyon occurs in sympatry or in allopatry to Lycalopex species. We tested for differences in size and shape between Cerdocyon groups and regressed both skull size and sexual size dimorphism against latitude and temperature, while controlling for spatial autocorrelation in the phenotypes. Southern Cerdocyon specimens present enlarged temporalis muscle and slender carnassial, both suggestive of a shift towards increased carnivory. Such a niche shift is interpreted as a mean to reduce competition to the larger Lycalopex species, which is still smaller than Cerdocyon . Consistently with the above, the degree of sexual shape and size dimorphism in Cerdocyon increases southward. We found a complex but coherent pattern of size and shape differentiation in Cerdocyon groups, which is consistent with the effects of both competition and Bergmann's rule. Cerdocyon reduces competition to Lycalopex by growing larger in the North. To the South, Cerdocyon is still larger, in keeping with Bergmann's rule, but strongly differs in skull shape from both its Lycalopex competitor and from any other Cerdocyon . Since the Southern Lycalopex species is much more similar in size to Cerdocyon than its Northern congeneric, this suggests that shape differences serve the goal of reducing competition between Cerdocyon and Lycalopex to the South, as size differences do to the North. The absence of the hypercarnivorous canid Speothos venaticus from the southern range of Cerdocyon may have allowed such a pattern to take place.
Stability indicating RP-HPLC method for simultaneous determination of amlodipine besylate and valsartan combination in bulk and commercial dosage forms.

The present study describes development and validation of simple, rapid, sensitive and stability indicating high- performance liquid chromatographic assay method for simultaneous determination of Amlodipine besylate and Valsartan in bulk as well as in commercial formulation. Analytical separation was achieved with RP Waters Symmetry C18 Column (150×4.6 mm) using a combination of methanol and potassium dihydrogen phosphate buffer (0.01 M) pH 2.5, in ratio 60:40 v/v with flow rate of 1 mL min �1 . The retention times for Amlodipine and Valsartan were found to be 4.6 and 7.6 min respectively. Both the drugs were exposed to thermal, photolytic, hydrolytic, and oxidative stress conditions individually as well as in combination, subsequently samples were analyzed by the proposed method. Detection was done by PDA detector at 238 nm. Method was found to be very sensitive as LOD found to be 20 ng/mL and 44 ng/mL for Amlodipine besylate and Valsartan respectively. The method was found to be specific and stability indicating as no interfering peaks of degradation compounds and excipients were noticed. The developed method was validated with respect to linearity, accuracy, precision, specificity, robustness as per International Conference on Harmonization (ICH) guidelines. The proposed method hence useful for the application in quality control laboratories for quantitative analysis of both the drug individually or in combination, as it is simple and rapid method with excellent accuracy and precision.
Performance Improvement of ACO-OFDM Indoor Optical Wireless Transmissions Using Partial Pre-Equalization

This paper analyzes the performances and presents the benets of partial pre-equalization for indoor optical wireless transmissions based on asymmetrically clipped optical orthogonal frequency division multiplexing (ACO-OFDM) with intensity modulation and direct detection (IM/DD). In particular, for diffuse indoor optical wireless channels, partial pre-equalization can reduce the optical transmit power over post-equalization at the same target bit error rate (BER) for point-to-point transmissions even with imperfect channel knowledge. To further im-prove its performance, bit loading is considered to minimize the optical transmit power of ACO-OFDM while maintaining a constant target BER. In addition, broadcast transmissions to multiple users with possibly dierent channel qualities are considered, where pre-equalization is not applicable. Finally, we specify an appropriate channel estimate at the transmitter for such broadcast transmissions.
Effects of alternative protein sources on rumen microbes and productivity of dairy cows

This experiment was conducted to investigate the effect of various protein sources on digestibility, rumen fermentation, milk yield and milk composition in dairy cows. Four Holstein Friesian native crossbred cows in early lactating were randomly assigned according to a 4x4 Latin square design. The dietary treatments containing different protein sources in concentrate diets were soybean meal (SBM), cassava hay (CH), Leucaena leucocephala (LL) and yeast-fermented cassava chips (YEFECAP), with ad libitum intake of urea-treated rice straw. Digestibility of DM, OM, NDF and ADF was not different among treatments (P>0.05) while CP digestibility was highest (P<0.05) in CH and YEFECAP supplemented groups. Ruminal NH3-N and BUN concentrations varied among protein sources and were highest in SBM and LL fed groups (P<0.05). Ruminal total volatile fatty acid (VFA) and propionic acid were found highest in cows receiving CH and YEFECAP (P<0.05). Ruminal fungi, proteolytic and cellulolytic bacteria were highest when YEFECAP was supplemented. Milk fat and milk protein were significantly increased (P<0.05) in cows fed with CH and YEFECAP. Based on this study, it was concluded that providing CH or YEFECAP as protein source in concentrate diets could improve rumen fermentation and milk production in lactating dairy cows fed on rice straw.
Manager App Portal at Continental: A Content, Collaboration, and Convenience App Selection that Works

PD. Dr. Jörg H. Mayer is the Head of Digital Finance, Accenture Strategy, Austria, Switzerland, Germany, Competence Center “Unternehmenssteuerungssysteme” at Darmstadt University of Technology, and Arbeitskreis “Digital Finance”, Schmalenbach-Gesellschaft, E-mail: joerg.mayer@ accenture.com Even apps for corporate management are respectable now. Manager app portals complement such “run-a-business” apps with apps that make managers’ business life easier. The “right” mix of apps makes the difference. Accommodating managers’ user perspective, we examine which apps disproportionately influence managers’ perception of information systems’ usefulness.
Effect of boron and zinc application on HXK1 and MAKR6 gene expression in strawberry

Boron (B) and zinc (Zn) are important microelements for normal plant activity; their effect have long been studied in numerous agronomical and molecular researches, whereas the interaction of B-Zn remains poorly understood at genomic and transcriptomic levels. Strawberry (fragaria x ananassa) plants were analyzed after single B (80 g/Hl of boron ethanolamine) or Zn (40 g/Hl of Zn-EDTA), and combined B+Zn (80 g/Hl of boron ethanolamine + 40 g/Hl of Zn-EDTA) foliar applications. Leaves, white and red fruits of two genotypes (Candonga and PZ600F13P2 breeding line) were studied. The microelement effects were observed in two conditions: short-term (1 day after treatment) and long-term (20 days after treatment). The differential transcriptomic profiles were analyzed applying RAPD-PCR method. Two genes, HXK1 and MAKR6 have been recognized in differently expressed sequenced amplicons and their expression level was measured using quantitative Real-Time PCR. Fertilizing had an influence on studied genes, their expression differed in relation to the genotype, time course and kind of treatment. Reaction of HXK1 and MAKR6 varied regarding the singular microelement treatments in front of Control (without any treatment) as well as relatively to the combined fertilizing, even if often the zinc effect was “masked” by boron influence in B+Zn treatment. The present study confirmed an initial hypothesis of a significant effects of B and Z in strawberry fruit development. The obtained results, even if they increase the knowledge about the B and Zn effects, could be considered as a first step to details this physiological mechanisms on strawberry fruit development.
Politics of Multilingualism in Roma Education in Early Soviet Union and Its Current Projections

This article presents the history of the politics of multilingualism (or lack thereof) in regard to Roma (formerly known as ‘Gypsies’). In the 1920s and 1930s in the newly established Union of Soviet Socialist Republics, against a backdrop of proclaimed principles of full equality of all peoples living in the new state, commenced a rapid creation of schools for Roma children with instruction in Romani mother-tongue along with special training of Roma teachers. The results achieved were impressive in regard to the general literacy of Roma communities, but nevertheless in 1938 the ‘Gypsy schools’ have been closed and Roma children were enrolled into mainstream schools lacking any elements of multilingualism. After World War II individual countries of Eastern Europe implemented various forms of special education for Roma children, neither of which however with elements of multilingualism. Only after the collapse of communist regimes in Eastern Europe, in the conditions of transition and the subsequent Euro-integration, various singular countries in the region have developed individual elements of multilingualism and educational policies targeting Roma children (e.g., introducing under various forms a Romani language instruction). Sporadically there even appeared proposals for teaching instruction conducted entirely in Roma mother-tongue, which were debated and rejected (including by Roma themselves).
Ontogenetic changes in mouth morphology triggers conflicting hypotheses of relationships in characid fishes (Ostariophysi: Characiformes)

Bryconamericus lethostigmus is the type-species of the monotypic genus Odontostoechus, diagnosed in part based on the presence of a unique tooth series in the premaxilla. Recently a new proposal of classification of the Stevardiinae placed Odontostoechus as a junior synonym of a monophyletic genus Bryconamericus sensu stricto, a genus characterized by the presence of two tooth series. Bryconamericus lethostigmus is redescribed herein and the single tooth series in the premaxilla is demonstrated to originate from merging of the external tooth row with the inner row during ontogeny refuting primary hypothesis of homology between the mouth morphology of B. lethostigmus and the genera Bryconacidnus, Ceratobranchia, Monotocheirodon, Othonocheirodus, Rhinopetitia and Rhinobrycon. A phylogeographic analysis indicated that the pattern described for the sympatric species Diapoma itaimbe is not mirrored by B. lethostigmus. The results also do not support the hypothesis of a new species in the rio Ararangua drainage.

Wind Motions around the Tropical Cirrus Using Simultaneous Radar and Lidar Observations over Gadanki (13.45°N, 79.18°E), India

The present study describes variation of peak linear depolarization ratio (LDR) with wind around the cloud altitude using simultaneous observation of winds and cirrus cloud for the first time using Indian MST radar and polarization lidar co-located over a low latitude station Gadanki (13.7°N and 79.2°E). Three different cases of passage of the cirrus at different altitudes are noticed, one during a North-East monsoon day and other two during South-West monsoon days. The zonal wind below the cloud height has shown similar variation with LDR during 02 November 2006 and the meridional wind within the cloud height during 25 July 2007 and 08 June 2006 has shown opposite variation with LDR. Even though there is a significant increase in zonal wind due to the existence of tropical easterly jet (TEJ) above cloud height during 25 July 2007 and 08 June 2006, also, the vertical wind is found to be continuously varying during 25 July 2007 and it is upward dominant in the initial stage and is mostly downward in the later stage of observation on 08 June 2006, there is a slight descent in cloud altitude only during 25 July 2007. Thus, the wind above the cloud height alone may not affect the ascent/descent of the cloud top altitude. The potential temperature gradient is high within the cloud heights when the cirrus present near the cold point tropopause indicates the maximum air-mass mixing near the tropopause.
