Authors: Rana Geeta , Sharma Ravindra , Singh S.P , Jain Vipul
Published: May 2019

This article seeks to empirically examine the impact of employee branding on job engagement and organizational commitment in Indian IT companies. The data was collected from 250 employees employed in various companies in Indian IT companies. Results revealed a strong positive association between employer branding and job engagement, job engagement and organizational commitment, and employer branding and organizational commitment. Further, job engagement showed a partial mediating effect on the link between employer branding and organizational commitment. This is the first empirical investigation to simultaneously examine associations among employer branding, job engagement, and organizational commitment. Practitioners could, with such knowledge, incorporate the most influential dimensions of employer branding in organizational culture.
Factors Affecting Implementation of Activity Based Costing in Selected Manufacturing Units in India
Authors: Arora Amit Kumar , Raju M.S.S.
Published: May 2019

The present article is an attempt to analyze the various factors affecting the adoption of an activity-based costing (ABC) system in selected manufacturing units in India. The following seven factors are considered: firm size, diversity of the product, percentage of overhead cost in total cost, listing of the company, cost audit compulsion, separate cost accounting department and the method of accounting. Logistic regression and a Chi Square test are applied to these factors and the use of an ABC system. On the basis of 72 sample units, the study found the size of the firm, percentage of overhead cost in total cost, cost audit compulsion and the method of accounting are statistically significant for the adoption of ABC system. While factors such as diversity of the product, separate cost accounting department and the listing of the company are found to not be statistically significant for the adoption of ABC system. The study has provided additional insights into areas relating to the factors affecting the implementation of ABC systems.

Published: May 2019

It is well known that the results from clinical laboratories support diagnosis, prognosis and patient treatment. Thus, test results must be relevant, accurate and reliable for patient care. Despite all the automation, errors that are classified as pre-analytical, analytical and post-analytical, are still present. International bibliographic data estimates that approximately 62.0% of the errors made in clinical laboratories are due to errors during the pre-analytical stage. The effect of the pre-analytical errors on the laboratory results has consequences that in many cases can lead to reduction of laboratory quality. In this study, the authors run a failure modes and effects analysis (FMEA) to analyze potential failure risks within the pre-analytical phase, in order to classify them according to severity and likelihood, based on the experience. In the present article, the authors performed an FMEA analysis of the pre-analytical phase of the testing process of a biochemistry laboratory.

Published: May 2019

This article aims to examine students' intentions toward entrepreneurships after their graduation and whether there are any significant differences between those students who intend to become entrepreneurs and those who do not intend to be so, in terms of their individual characteristics and contextual factors. The data was collected through a self-administrated questionnaire from a convenient sample of 250 business students in the two universities (Kuwait University and PSUT University) in Kuwait and Jordan. The findings indicated there were significant differences between the two groups of students who intend to become entrepreneurs and those who do not intend in terms of their individual characteristics factors (optimism, innovativeness, risk taking tolerance, and the need for achievement) and in terms of their contextual factors. The research has been finalized with some practical implications and recommendations.
Public Policy and the Sustainability of Third Sector Social Enterprises
Authors: Maher Chi
Published: May 2019

This article examines how public policy is shaping and bolstering small social enterprise sustainability in the UK regions. As government interests in social enterprise activities and contribution to public services delivery grows, the need to provide regional qualitative data that informs policy makers of the challenges and sustainability needs of these organisations is paramount. Semi-structured interviews were conducted with 26 Chief Executive Officers (CEOs) and managers in three UK regions to ascertain how policy framework poses challenges and/or boosts small third-sector social enterprise sustainability. The research findings suggest strategies to improve sustainability will include changes in public policy to help these organisations to develop and sustain appropriate effective services. The research contributes to empirical research investigating the insinuation of regional funding variations on small social enterprise development and sustainability.
Online Communities. Benefits and Risks
Authors: Graziani Elena , Petrini Fausto
Published: May 2019

This article reviews empirical studies from 2008 to 2017 on the effects of participating in online communities. The review uses three databases: PubMed, Scopus and ScienceDirect. The criteria are: (1) online community aimed to provide support by and for people with a common problem; (2) the content of the sessions was determined by users; (3) members met via the Internet; (4) online community was available 24/7; (5) online community access was free and open to everyone with an Internet connection. Of the articles, 13 of 105 met the inclusion criteria. Seven studies reported positive changes: informational and emotional support, increased sense of belonging, less isolation, better medical understanding. Six articles also considered risks: the rise of the level of stress because of successes or failures of other users, the addiction to the forum and the consequent isolation from real relationships.
A Study on Lifetime Enhancement and Reliability in Wearable Wireless Body Area Networks
Authors: Vasanthamani Saranya
Published: May 2019

The wireless body area network (WBAN) which consists of wearable or implantable sensor nodes, is a technology that enables pervasive observing and delivery of health related information and services. The radio-enabled implantable medical devices offer a revolutionary set of applications among which we can point to precision drug distribution, smart endoscope capsules, glucose level observers and eye pressure detecting systems. Devices with WBAN are generally battery powered due to sensitivity and criticality of the data carried and handled by WBAN, reliability becomes a critical issues. WBAN loads a high degree of reliability as it openly affects the quality of patient observing. Undetected life-threatening circumstances can lead to death. A main requirement is that the health care professionals receive the monitored data correctly in emergency situations. The major objective is to achieve a reliable network with minimum delay and maximum throughput while considering power consumption by reducing unnecessary communication.
Fast Single Image Haze Removal Scheme Using Self-Adjusting
Authors: Roy Sangita , Chaudhuri Sheli Sinha
Published: May 2019

At present the classical problem of visibility improvement is hot topic of research. An image formation optical model is presented where a clear day image has high contrast with respect to an image plagued with bad weather. A degraded daytime image has high intensity with minimum deviation among pixels in every channel. No reference digital image haze removal is a problem. The static haziness factor for all types of images cannot be applicable for effective haze removal. A minimum intensity channel of the three RGB channels is estimated as transmission of an image with a dynamic haziness factor to be a ratio of minimum to maximum pixel intensity of the hazy image. Adaptive contrast, extinction coefficient, the maximum visible distance of hazy images as well as dehazed images from each image are evaluated uniquely. The resulting high-quality haze free image with linear computational complexity O(n) is appropriate for real time applications. The effectiveness of the technique is validated by quantitative, and qualitative evaluations.
An Integrated Approach to Performance Evaluation of Enterprise Resource Planning (ERP) System Implementation
Authors: Wanchai Paweena
Published: May 2019

In spite of the immense expenses related with enterprise resource planning (ERP) systems execution and use, its effect on organizational performance stays vague. The goal of this study was to empirically examine the impact of ERP implementation and use on the long-term performance of organizations. This research leverages three fundamental specifications for the examination of impacts as follows: performance ratios (ROA, ROE, ROI, ROS), labor productivity (production function), and stock market valuation (Tobin's Q). This research used a total of six years of financial data from 47 organizations in Thailand that implement and use ERP system. The findings reveal that a post-adoption period of more than four years may be needed in order to observe a significant impact from ERP investments on organizational performance.
Shoppers' Intention to Provide Online Reviews
Authors: Tata Sai Vijay , Prashar Sanjeev , Parsad Chandan
Published: May 2019

With an increase in e-commerce activity, online reviews have become a pertinent source of information for shoppers. Existing research is limited to examining select predictors of shoppers' intention to write reviews; however, there exists a gap in deciphering the role of review involvement in intention to write reviews. The present study pertains to the influence of the usefulness of site and product, and shoppers' satisfaction, and also on the intention to write reviews online. Besides this, the article also explores the moderating role of review involvement on the relationship between shopper satisfaction and their intention to post reviews. The study reveals a few interesting and counter-intuitive findings that add to literature and practice in understanding online review posting behaviour. Theoretical and managerial implications based on the findings are also presented.

Future Lyme disease risk in the south-eastern United States based on projected land cover
Authors: Stevens Logan K. , Kolivras Korine N. , Hong Yili , Thomas Valerie A. , Campbell James B. , Prisley Stephen P.
Published: May 2019

Lyme disease is the most significant vector-borne disease in the United States, and its southward advance over several decades has been quantified. Previous research has examined the potential role of climate change on the disease’s expansion, but no studies have considered the role of future land cover upon its distribution. This research examines Lyme disease risk in the south-eastern U.S. based on projected land cover developed under four Intergovernmental Panel on Climate Change Scenarios: A1B, A2, B1, and B2. Land cover types and edge indices significantly associated with Lyme disease in Virginia were incorporated into a spatial Poisson regression model to quantify potential land cover suitability for Lyme disease in the south-eastern U.S. under each scenario. Our results indicate an intensification of potential land cover suitability for Lyme disease under the A scenarios and a decrease of potential land cover suitability under the B scenarios. The decrease under the B scenarios is a critical result, indicating that Lyme disease risk can be decreased by making different land cover choices. Additionally, health officials can focus efforts in projected high incidence areas.

Published: May 2019

Alphitobius diap]erinus has been recommended for mass-production as feed in a rearing facility because of its small size and short biological cycle. This study evaluated the effects of wheat bran and casein or their blend as insect diets on growth performance and feed conversion efficiency of A. diaperinus larvae in the laboratory. Casein and wheat bran were the protein and carbohydrate sources of choice, respectively, for diet preparation. Five experimental diet treatments to be tested were designed as follows: control (100% casein), T1 (75% casein +25% wheat bran), T2 (50% casein +50% wheat bran), T3 (25% casein +70% wheat bran), and T4 (100% wheat bran). A total of 150 new hatched larvae were randomly allotted to one of the five dietary treatments, with three replicates (10 hatched larvae per replicate). The standard colonies were composed of 10 hatched larvae, without distinction of sex, reared in a plastic box (14×8×5 cm) provided with aeration holes on the top. The evaluation of A. diaperinus larvae included growth performance and feed efficiency. Using casein and wheat bran blends for diet had a positive effect on weight gain and feed conversion ratio of A. diaperinus larvae, including an increase in average larval survival and average larval weight. Using casein and wheat blends (75% casein +25% wheat bran or 25% casein +70% wheat bran) as insect-rearing diet will allow effective utilization of the feed for poultry when using the edible portion of mealworms before reaching the pupae stage.

Published: May 2019

Colony integrity and survival in honeybees is regulated by chemical signals that are actively produced by glands and synergically transmitted between the members. A number of these signals regulate the typical age-related division of labor among the worker bees performing different tasks at different ages. In this study, the analysis of the cuticular profiles in Apis mellifera ligustica Spinola, 1806 workers at various tasks (newly emerged, nurse and forager bees) was performed using in vivo solid-phase microextraction gas chromatography-mass spectrometry (SPMEGC- MS). The use of in vivo SPME shed new light on the complexity of the molecular pattern on the epicuticle of honeybees. The identified molecules are mainly hydrocarbons, saturated and unsaturated carboxylic acids, and to a less extent, esters, sterols, aldehydes, and alcohols. Their relative abundance between the three task groups was evaluated using descriptive statistics and multivariate pattern recognition analysis (i.e., principal component analysis, PCA, and linear discriminant analysis, LDA). Eleven molecules namely nonacosane, pentacosane, (Z)-12-pentacosene, 11-tricosene, 11-methylnonacosane, squalene, 13-methylheptacosane, heptacosane, heneicosane, docosane and tricosane, occur with high frequency in newly emerged, nurse, and forager bees. The compounds that contributed the most for the separation of the three task groups in the PCA were pentacosane, (Z)-12-pentacosene, 13-methylheptacosane and squalene; while for LDA, nonacosane, 11-methylnonacosane and pentacosane were the molecules that contributed most to the discrimination.
Demographic change: Ecological and polycentric challenges for white Christianity in urban South Africa
Authors: Resane Kelebogile T.
Published: May 2019

This article demonstrates how white Christianity in urban South Africa is fated by demographic change. The repeal of apartheid in 1994 enacted some sociocultural changes in urban South Africa. The white population exited the city and town centres, followed by the black South Africans. The historical relationship of the government under the National Party (NP) and the Dutch Reformed Church (DRC) led to latters’ redundancy in the cities. The cultural development towards multiculturalism led to polycentric focus where the suburban peripheries and the city centres experience some form of socio- and cultural-economic developments. Two proposals are made to redress the situation. Firstly, a rethinking was suggested of the theology of the city, which should always demonstrate solidarity with the poor and the marginalised trapped within the decadent city culture. Secondly, a missiological refocus was suggested, which should pursue, embrace and include activities that are not paternalistic.
Mammary analog secretory carcinoma parotid gland: Case report of a recently described tumor with review of literature
Authors: Gaopande Vandana L. , Kulkarni Maithili M. , Khandeparkar Siddhi G. S. , Joshi Avinash R.
Published: May 2019

Mammary analog secretory carcinoma (MASC) is a low-grade malignant tumor of salivary glands. It is so named because of its cytohistopahological, immunohistological, and cytogenetic resemblance to secretory carcinoma of the breast. Since the first description of this tumor in 2010, about 70 cases have been reported in literature. We report a case of this recently described tumor in a 21-year-old female. The radiological diagnosis of her parotid swelling was pleomorphic adenoma. The cytological evaluation was suggestive of oncocytoma. The histopathology showed a low-grade malignant neoplasm and the differential included papillary variant of acinic cell carcinoma, oncocytic variant of mucoepidermoid carcinoma, and MASC. Immunohistochemistry confirmed the diagnosis of MASC. We have included a brief review of literature.
CytoKey: Identification Key for the Chagas Disease Vectors of the Largest Brazilian Urban Center (São Paulo State), Based on Cytogenetic Data

Published: May 2019

Chagas disease is caused by the protozoan Trypanosoma cruzi. This disease is distributed in 21 Latin American countries, where it is mostly vector-borne. In Brazil, there are 68 triatomine species. To date, the epidemiological surveys indicate that the state of São Paulo presents 11 species of triatomines, and most of these species have already been collected in a home environment and found to be infected with T. cruzi. Problems in correctly identifying species can lead to incorrect panorama of distribution of Chagas disease vectors. Thus, we developed an identification key for the triatomines of the state of São Paulo, based on cytogenetic data. With the exception of Panstrongylus diasi that does not present cytogenetic data available in the literature, all species were differentiated by cytogenetic characteristics. We emphasize the importance of using this key as a simple and objective tool in the entoepidemiological surveys conducted by the vector control programs.

Published: May 2019

Cutaneous leishmaniasis (CL) remains one of the world’s most prevalent neglected diseases, particularly in developing countries. Identification of the involved Leishmania species is an important step in the diagnosis and case management process. In this study, we tested simple, rapid, and highly sensitive loop-mediated isothermal amplification (LAMP) assays for Leishmania DNA species-specific detection from cutaneous lesions. Two LAMP assays, targeting cysteine protease B (cpb) gene, were developed to detect and identify Leishmania major and Leishmania tropica species. Loop-mediated isothermal amplification specificity was examined using DNA samples from other Leishmania species and Trypanosoma species. No cross-reactions were detected. The developed LAMP assays exhibited sensitivity with a detection limit of 20 fg and 200 fg for L. major and L. tropica, respectively. Both tests were applied on clinical samples of CL suspected patients living in endemic Tunisian regions and compared with kinetoplast DNA quantitative PCR (qPCR), microscopic, and conventional cpb-based polymerase chain reaction (PCR) assays. Our LAMP tests were able to discriminate between L. major and L. tropica species and showed a sensitivity of 84% and a specificity of 100%. However, when compared with the performance of the diagnostic tests with latent class analysis (LCA), our LAMP assays show a sensitivity of 100%. These assays can be used as a first-line molecular test for early diagnosis and prompt management of CL cases in public health programs.
O Adolescente Infrator e o Outro Social: Reflexões Psicanalíticas sobre a Indiferença
Authors: Guerra Andréa Máris Campos , Otoni Marina De Melo Silva Soares
Published: May 2019

Este artigo tem como objetivo analisar a indiferença, a partir da experiência com adolescentes em conflito com a lei, focando-se na relação com o técnico responsável pelo seu acompanhamento na medida socioeducativa em meio aberto, com o intuito de compreender como é possível operar com esses jovens na medida. Para realizá-la, elegemos a psicanálise como referencial teórico. Como a indiferença não é um conceito psicanalítico, mas um termo recolhido da experiência com esses jovens, a fim de proceder à investigação dessa experiência, recorremos ao conceito de pulsão, em Freud, para definir a indiferença. Balizamos a discussão com a noção de transferência. Utilizamos um fragmento de caso de adolescente que cumpriu a medida de Prestação de Serviço à Comunidade, no qual a indiferença se apresentava como um obstáculo para a realização do trabalho proposto. Localizamos, ao final dessa investigação, a retificação do Outro como estratégia para operar com jovens indiferentes na medida.

Cultuursociologie in de Lage Landen
Authors: Schaap Julian , Van Eijck Koen , Michael Janna
Published: May 2019

Cultuursociologie heeft misschien geen breed gedeelde visie, geen doxa, maar de vraag is of dat überhaupt nodig is: het lijkt er op dat de noodzaak voor een definitie hoofdzakelijk bedoeld is voor hen buiten de cultuursociologie. Zo stellen Alexander, Jacobs en Smith (2012: 5) dat de discipline zelden doet aan positionering maar juist ‘gets on with explaining stuff, or with developing tools to do this explaining’. Met andere woorden, ‘broad calls for legitimation do not reflect routine practice but rather are appeals to an imagined audience of outsiders’ (ibid.). Maar dat pragmatisme stelt ons voor een dilemma; hoe graag wij ook gauw tot de inhoud willen komen, Sociologie is een tijdschrift waarvan het brede lezerspubliek minder ‘imagined’ is dan Alexander et al. stellen. Een degelijke inleiding van dit themanummer kan dus niet zonder een introductie in de cultuursociologie en haar vele gezichten. Ook hier geldt dat de cultuursociologische bijdragen aan de sociale wetenschappen dusdanig divers zijn dat de ‘task of explaining the merits of these contributions for the consolidation of cultural sociology is restricted to the editors’ introductions’ (Lima Neto 2014: 938). Daarom, een korte introductie in de cultuursociologie.
De nieuwe Hendrix. Witheid als scheidslijn in de evaluatie van rockmuziek in Nederland en de Verenigde Staten.
Authors: Schaap Julian , Berkers Pauwke
Published: May 2019

Popular music can have a function in the creation of boundaries betweengroups, particularly regarding race and ethnicity. Music genres such as rockor hip-hop do not only reflect ethno-racial groups, but are often structuredalong ethno-racial lines. Based on a quantitative and qualitative analysisof 577 rock music album reviews, this article investigates (i) to what extentethno-racial boundaries are (re)produced and/or contested in the critical andconsumer reception of rock music in the Netherlands and the United Statesbetween 2003 and 2013, (ii) to what extent professional reviewers andconsumer reviewers differ from each other regarding ethno-racial classificationsin their reception of rock music, and (iii) whether there is a differencebetween the ethno-racial context of the Netherlands and the United States.Albums by non-white artists tend to receive lower evaluations than thoseby white artists, particularly when reviewed by consumer critics. Althoughboth types of reviewers often ignore talking about race – echoing a colourblindideology, professional critics are more explicit and colour-consciousregarding non-white participation in rock music. Furthermore, five differentmechanisms are employed by reviewers as part of ethno-racial boundarywork: (i) ethno-racial comparisons, (ii) inter-genre comparisons, (iii) positiveethno-racial marking, (iv) negative ethno-racial marking and (v) minimizationand irony.
Waarom er minder empirisch bewijs bestaat voor de contacttheorie dan velen beweren: Een kwantitatieve cultuursociologische kritiek
Authors: Manevska Katerina , Achterberg Peter , Houtman Dick
Published: May 2019

The finding that ethnic prejudice is particularly weakly developed among those with interethnic friendships is often construed as confirming the so-called ‘contact theory’, which holds that interethnic contact reduces racial prejudice. This theory raises cultural-sociological suspicions, however, because of its tendency to reduce culture to an allegedly ‘more fundamental’ realm of social interaction. Analysing data from the first wave of the European Social Survey, we therefore test the theory alongside an alternative cultural-sociological theory about culturally driven processes of contact selection. We find that whereas interethnic friendships are indeed culturally driven, which confirms our cultural-sociological theory, contacts with neighbours and colleagues do indeed affect ethnic prejudice. They moreover do so in a manner that is more complex and culturally sensitive than contact theory suggests: while positive cultural stances vis-à-vis ethnic diversity lead interethnic contact to decrease ethnic prejudice, negative ones rather lead the former to increase the latter.
Gekanaliseerd onbehagen? PVV-stemmers, niet-stemmers, en hun betekenisvolle politieke agency
Authors: Kemmers Roy
Published: May 2019

The channelling discontent thesis contends that populist parties form an efficacious exhaust valve, providing their voters with democratic fulfilment. Building on in-depth interviews with PVV-voters and (deliberate) non-voters, I assess that assumption by comparing these citizens’ political efficacy. The analysis shows that differences in political efficacy are not explained by voting behaviour, as the thesis would assume, but rather by the inductively conceptualized dimension of power orientation. This highlights not just the value, but also the (future) potential of a cultural-sociological approach to studying the political domain.
Is sociologie klaar voor de mediasamenleving?
Authors: Kuipers Giselinde
Published: May 2019

Is sociology ready for media society? A quick survey of recent sociology journals shows that as far as sociologists are concerned, social life is not very different from how it was in the 1980s: primarily based on face-to-face interactions, written communication, print media and an incidental phone call. The essay then presents a ‘bare bones’ version of sociology to show how the recent processes of accelerated mediatisation affects the basic ingredients of sociological analysis – interaction, culture and social structure – as well as the relation between these ingredients. It ends with an invitation to sociologists. For each study you do: ask yourself could this be done with the same methods or concepts in 1975? If so, consider adapting your design or conceptual framework to incorporate at least some elements related to the recent wave of mediatisation.

Abstract. Haze pollution caused by PM2.5 is the largest air quality concern in China in recent years. Long-term measurements of PM2.5 and the precursors and chemical speciation is crucially important for evaluating the efficiency of emission control, understanding formation and transport of PM2.5 associated with the change of meteorology and for accessing the impact of human activities to regional climate change. Here we reported long-term continuous measurements of PM2.5, chemical components, and their precursors at a regional background station, the Station for Observing Regional Processes of the Earth System (SORPES), in Nanjing eastern China since 2011. We found that PM2.5 at the station has experienced a substantial decrease (−9.1 %/yr), accompanied with even much significant reduction of SO2 (−16.7 %/yr), since the national "Ten measures" for air took action in 2013. Control of open biomass burning and fossil-fuel combustion are the two dominant factors that influence the PM2.5 reduction in early summer and winter, respectively. In cold season (November–January), increased nitrate fraction was observed with more NH3 available from a substantial reduction of sulfate, and the change of year-to-year meteorology contributed to 24 % of the PM2.5 decrease since 2013. This study highlights several important implications on air pollution control policy in China.
Quasi-separatrix layers induced by ballooning instability in the near-Earth magnetotail
Authors: Zhu Ping , Wang Zechen , Chen Jun , Yan Xingting , Liu Rui
Published: May 2019

Abstract. Magnetic reconnection processes in the near-Earth
magnetotail can be highly three-dimensional (3-D) in geometry and dynamics,
even though the magnetotail configuration itself is nearly two-dimensional
due to the symmetry in the dusk–dawn direction. Such reconnection processes
can be induced by the 3-D dynamics of nonlinear ballooning instability. In
this work, we explore the global 3-D geometry of the reconnection process
induced by ballooning instability in the near-Earth magnetotail by examining
the distribution of quasi-separatrix layers associated with plasmoid
formation in the entire 3-D domain of magnetotail configuration, using an
algorithm previously developed in the context of solar physics. The 3-D
distribution of quasi-separatrix layers (QSLs) as well as their evolution
directly follow the plasmoid formation during the nonlinear development of
ballooning instability in both time and space. Such a close correlation
demonstrates a strong coupling between the ballooning and the corresponding
reconnection processes. It further confirms the intrinsic 3-D nature of the
ballooning-induced plasmoid formation and reconnection processes, in both
geometry and dynamics. In addition, the reconstruction of the 3-D QSL
geometry may provide an alternative means of identifying the location and
timing of 3-D reconnection sites in the magnetotail from both numerical
simulations and satellite observations.
Historic hydrological droughts 1891–2015: systematic
characterisation for a diverse set of catchments across the UK
Authors: Barker Lucy J. , Hannaford Jamie , Parry Simon , Smith Katie A. , Tanguy Maliko , Prudhomme Christel
Published: May 2019

Abstract. Hydrological droughts occur in all climate zones and can have severe impacts on society and the environment. Understanding historical drought occurrence and quantifying severity is crucial for underpinning drought risk assessments and the developing drought management plans. However, hydrometric records are often short and capture only a limited range of variability. The UK is no exception: numerous severe droughts over the past 50 years have been well captured by observations from a dense hydrometric network. However, a lack of long-term observations means that our understanding of drought events in the early 20th century and late 19th century is limited. Here we take advantage of new reconstructed flow series for 1891 to 2015 to identify and characterise historic hydrological droughts for 108 catchments across the UK using the Standardised Streamflow Index. The identified events are ranked according to four event characteristics (duration, accumulated deficit, mean deficit and maximum intensity), and their severity reviewed in the context of events of the recent past (i.e. the last 50 years). This study represents the first national scale assessment and ranking of hydrological droughts. Whilst known major drought events were identified, we also shed light on events which were regionally important such as those in 1921 and 1984 (which were important in the south-east and north-west of the UK, respectively). Events which have been poorly documented such as those of the 1940s in the post-war years, or the early 1970s (prior to the landmark 1975–1976 event), were found to be important in terms of their spatial coverage and severity. This improved knowledge of historic events can support improved long-term water resources planning approaches. Given the universal importance of historical drought appraisal, our systematic approach to historical drought assessment provides a methodology that could be applied in other settings internationally.
Adverbial clauses and adverbial concord
Authors: Endo Yoshido , Haegeman Liliane
Published: May 2019

This paper speculates that the merge site of an adverbial clause, i.e. its external syntax, is determined by its derivational history, i.e. its internal syntax. Starting from the distinction between central adverbial clauses and peripheral adverbial clauses, it is first shown that the degree of integration of an adverbial clause correlates with its internal syntax, i.e. the availability of left peripheral functional material. The correlation can be informally stated as follows “the more structure is manifested in the adverbial clause, the higher it is merged”. This paper develops a derivational account for this correlation. The proposal adopts the movement derivation of adverbial clauses, according to which, like relative clauses, adverbial clauses are derived by movement of a specialized IP-related operator (aspectual, temporal, modal, etc) to the left periphery. The paper explores observations drawn from the traditional literature on Japanese grammar (Minami 1974; Noda 1989; 2002) to the effect that the amount of TP-internal functional structure in an adverbial clause also correlates with the presence of specialized functional particles in the matrix clause with which the clause merges. Specifically, we explore Japanese data discussed in Endo (2011; 2012). It is proposed that the merger of an adverbial clause with the associated main clause is determined by the label of the adverbial clause, itself the result of the movement derivation.

Mineralogy is a fundamental characteristic of a given rock mass throughout the mining value chain. Understanding bulk mineralogy is critical when making predictions on processing performance. However, current methods for estimating complex bulk mineralogy are typically slow and expensive. Whole-rock geochemical data can be utilized to estimate bulk mineralogy using a combination of ternary diagrams and bivariate plots to classify alteration assemblages (alteration mapping), a qualitative approach, or through calculated mineralogy, a predictive quantitative approach. Both these techniques were tested using a data set of multielement geochemistry and mineralogy measured by semiquantitative X-ray diffraction data from the Productora Cu-Au-Mo deposit, Chile.

Using geochemistry, samples from Productora were classified into populations based on their dominant alteration assemblage, including quartz-rich, Fe oxide, sodic, potassic, muscovite (sericite)- and clay-alteration, and least altered populations. Samples were also classified by their dominant sulfide mineralogy. Results indicate that alteration mapping through a range of graphical plots provides a rapid and simple appraisal of dominant mineral assemblage, which closely matches the measured mineralogy.

In this study, calculated mineralogy using linear programming was also used to generate robust quantitative estimates for major mineral phases, including quartz and total feldspars as well as pyrite, iron oxides, chalcopyrite, and molybdenite, which matched the measured mineralogy data extremely well (R2 values greater than 0.78, low to moderate root mean square error). The results demonstrate that calculated mineralogy can be applied in the mining environment to significantly increase bulk mineralogy data and quantitatively map mineralogical variability. This was useful even though several minerals were challenging to model due to compositional similarities and clays and carbonates could not be predicted accurately.
Atomic Proposition and 1-Order Predicate Function for Dialectical Logic
Authors: Jiang Yaozhi
Published: May 2019

This paper has completed main fields of making dialectical logic pure mathematically, it is involved both atomic proposition and 1-order predicate function for dialectical logic, and by state-dual, true-valued function vector, state-contradiction law into basic logic law. In addition, also defines true-valued function for logic operators so that more easy to represent atomic proposition. Some examples are given and shown that Boolean algebra, as a special case of dialectical logic, is how to operate hybridize-able with dialectical logic.
¿Arrepentimiento? ¿Justificación? ¿Voces perdidas? Luces y sombras de los testimonios de los perpetradores en la Sudáfrica post-apartheid
Authors: Pineau Marisa , Flores Celina
Published: May 2019

La experiencia de la transición política sudafricana del régimen del apartheid a una democracia multipartidaria en los primeros años de la década de 1990 ha sido vista como un modelo exitoso de transición pacífica, en especial por su abordaje de las graves violaciones a los Derechos Humanos en el pasado reciente. La Comisión de Verdad y Reconciliación que se creó con ese fin y funcionó entre 1996 y 2001 fue la institución central en este proceso. En este trabajo pretendemos discutir en profundidad algunas soluciones milagrosas sobre la transición sudafricana a partir del análisis del discurso de los perpetradores. En primer término, explicaremos los alcances del término perpetrador en el contexto sudafricano. Después trabajaremos sobre los espacios públicos y privados en los cuales estas voces se empezaron a expresar y posteriormente veremos qué tipo de declaración realizaron éstos sobre el pasado que protagonizaron. Consideramos que el desarrollo de estos ejes darán una mirada más compleja, relativizando algunos discursos que subrayan el éxito de la experiencia, sobre todo aquellos recreados en el ámbito de la justicia transicional.
De Masterman a Orwell: el debate sobre la propaganda de estado en el Reino Unido (1914-1945)
Authors: García Fernández Hugo
Published: May 2019

Ellul, Chomsky y Keane, entre otros autores, han señalado la contradicción entre el principio liberal de libertad de prensa y la tendencia de las democracias contemporáneas a manipular la información para legitimarse y fabricar consensos. Este artículo busca el origen de esta situación en los debates sobre la propaganda de Estado que se desarrollaron en el Reino Unido durante y entre las dos guerras mundiales (1914-1945). Este episodio no se ha estudiado de manera monográfica, pese a afectar a un régimen pionero tanto en la historia del liberalismo como en el campo de la comunicación política. Más allá de su influencia en las decisiones de sus Gobiernos, las reflexiones de los intelectuales, altos cargos y profesionales de la comunicación británicos reflejan la ambivalencia con que la opinión del país aceptó la idea de una propaganda democrática, a la vez que iluminan conceptos clave de la cultura política liberal como la democracia, el totalitarismo, la nación, la cultura y la sociedad de masas.
Intolerable, peligrosa, imprescindible: intelectuales y políticos estadounidenses ante la problemática de la propaganda en el periodo de entreguerras (1919-1939)
Authors: Migliucci Dario
Published: May 2019

El presente artículo se propone reconstruir el debate intelectual sobre manipulación de la opinión pública que se desarrolló en Estados Unidos en el periodo de entreguerras. Se analizarán además las actividades contra la propaganda que fueron llevadas a cabo por exponentes del mundo de la cultura, por un lado, y por los poderes ejecutivo y legislativo, por otro. La hipótesis de la investigación es que a lo largo del periodo de entreguerras se fue configurando en Estados Unidos una forma particular de entender la propaganda, una visión pedagógica de las actividades de persuasión que perduraría en el tiempo, convirtiéndose en una peculiaridad de la nación norteamericana.
Factores de nacionalización: nacionalismo, sociedad civil y prácticas culturales
Authors: Giori Pablo
Published: May 2019

Es común leer en la bibliografía especializada que la nación es construida tanto desde arriba como desde abajo, que es una idea y un proyecto pero también un sentimiento. Al mismo tiempo, se viene destacando cada vez más la importancia que tienen ciertos factores culturales en la construcción y reproducción del nacionalismo. Este artículo sigue estas líneas de reflexión y contribuye al debate sobre la nacionalización, enriqueciendo la perspectiva historiográfica con las aportaciones de los trabajos comparativos entre naciones desde una metodología cualitativa entre historia, sociología, antropología, psicología social y ciencias políticas. El objetivo es pensar desde los casos del Quebec y Cataluña los aspectos culturales del nacionalismo, los factores de nacionalización, la socialización y el rol de las prácticas culturales para entender un proceso clave del nacionalismo: la nacionalización.
Articular la nación. La María de Ayguals de Izco y la nacionalización española (1845-1850)
Authors: Andreu Miralles Xavier
Published: May 2019

Los estudios más recientes sobre el nacionalismo subrayan el carácter narrativo de las identidades nacionales y la necesidad de cuestionar los modelos teóricos elitistas de construcción nacional. En el texto parto de estas propuestas y del concepto de “articulación” de Michael Kennedy y Ronald Suny para estudiar la interacción que se produce María, la hija de un jornalero (1845-1846) de Wenceslao Ayguals de Izco. Estudio la nacionalización que lleva a cabo Ayguals de determinados lenguajes (honor, amor, religión) que eran fácilmente reconocibles por sus lectores. Posteriormente analizo las estrategias narrativas que utiliza y que pudieron contribuir a que la novela fuera leída nacionalmente. Concluyo con algunas reflexiones sobre el alcance social que pudo tener la novela de Ayguals de Izco.
Deconstruyendo el vilipendio de las masculinidades musulmanas en los Estados Unidos
Authors: Bosch Vilarrubias Marta
Published: May 2019

Para entender las políticas internacionales del presidente Donald J. Trump, y en especial el veto migratorio puesto en marcha en junio de 2017, el presente artículo deconstruye la historia discursiva de vilipendio de las masculinidades árabes en los Estados Unidos. Empezando por los primeros encuentros coloniales, expuestos por Edward W. Said en Orientalismo, el artículo traza un recorrido histórico desde el siglo XVIII hasta la actualidad, haciendo especial hincapié en la patologización y adscripción de anormalidad al varón musulmán a través de su oximorónica caracterización como hipermasculino y emasculado. El articulo luego se centra en las consecuencias del 11 de septiembre de 2001, tomando como ejes de la reflexión los conceptos de abyección (Kristeva), biopolítica y gubernamentalidad (Foucault), y necropolítica (Mbembe), para así explicar como las masculinidades musulmanas fueron vilificadas al ser concebidas como masculinidades queer-ificadas y fallidas (Puar), contrapuestas a la masculinidad hegemónica occidental, y como Donald  Trump ha re-apropiado estos discursos para intentar aseverar su propia hombría.
Flexibilidad para la acción política: las fuentes doctrinales del pensamiento económico de Pasqual Maragall
Authors: San Julián Arrupe Javier , Serrano Robles Eloi
Published: May 2019

El ideario de Pasqual Maragall es ampliamente conocido y se ha manifestado en su dilatada actividad política y gestora, como dirigente del Partit dels Socialistes de Catalunya (PSC), alcalde de Barcelona y presidente de la Generalitat de Catalunya. Sus ideas políticas, sociales y referentes a cuestiones de organización urbana han sido expuestas en muchas ocasiones a través de medios muy diversos. Sin embargo, ciertos aspectos de la formación de su pensamiento han pasado desapercibidos en la vasta actividad del personaje. Uno de ellos es su formación como economista, en Barcelona y en Nueva York. Maragall redactó algunos trabajos académicos relevantes en esta etapa en los que mostró su preferencia por la obra de economistas de orientación ricardiana, marxista y postkeynesiana. A partir de una revisión de estos escritos económicos, este artículo trata de poner de relieve las fuentes doctrinales que Maragall utilizó y que indudablemente sirvieron a conformar su pensamiento posterior. Aunque aquí no se establece una correlación directa entre las ideas de estos economistas y la actividad posterior de Maragall, una introducción a las principales referencias económicas de su época académica parece necesaria para comprender mejor a este personaje central en la vida política catalana y española de los últimos años.
