The Essential Traits of Tourism Today: Values, Motivations and Trends
Authors: Montebelli Matteo , Vavassori Massimiliano
Published: February 2020

Tourism is driven by tourists and a traveller behaviour that has evolved over time, driven by changes in society. Trips have become shorter, there are a progressive disintermediation and cross-contamination, and increasingly self-defining function as a time of personal realisation. Not just ‘where’ but also ‘how’ people travel is the key. The diverse motivations behind travel behaviour and holidays have gradually multiplied over the years and aspects traditionally considered of little or no relevance to tourism are gaining importance.
Global Tourism and Language Learning: the Study Abroad Sector
Authors: Salazzaro Andrea
Published: February 2020

Over the years, the globalisation of tourism has seen new players entering in the competition arena. The competition in the industry is high with offers of many products and travel experiences. The buyer decision is mostly influenced by the experience needed in a specific moment of the life. Audiences can be grouped in bubbles formed by niches of customers with same needs and intentions. The audience in the bubbles is temporary and the movement from a bubble to another depends by the needs at a specific stage of their life. In the last decade, we have observed an increase in the demand from people wishing to learn a foreign language, as a result there has been a corresponding increase in demand for holidays which include intensive language courses. A new profile of tourist is nowadays active and the tourism industry has seen the entrance of strong competitors that can offer a leisure product with a surplus: the language learning. The paper gives an overview of the dynamics of the sector and how it contributes to the growth of the global tourism industry.

Transparency is also fundamental to an effective interaction with a variety of stakeholders, especially for companies operating in global markets. The Internet can significantly contribute to the widespread dissemination of complete and timely information on a company’s activities and performance. Combining theoretical and empirical research, this article focuses on web-based integrated CSR reporting and presents an empirical investigation whose results emphasise the necessity to improve online communication on sustainability matters, including in CSR-oriented companies.
Exploring Corporate Social Responsibility in a Social Business: The Workers Beer Company
Authors: Murdock Alex , Dolezal Nick
Published: February 2020

The Workers Beer Company is a long-established company owned by the Battersea and Wandsworth Trades Union Council in London. The Trade Council is an umbrella group bringing together trade union branches in South London to promote trade union activity and membership locally. The Company’s focus is to raise funds for ‘left’ organisations, promote trade union membership and support organisations to deliver ethical services through mobilising its volunteer base to run bars and sell drinks music festivals. Once costs are met company surpluses are either reinvested or are devoted to social purposes. This paper explores integrated CSR through a case study of an organisation that has provided support for the last 30 years at globally recognised festivals, developed ethical businesses and donated millions of pounds to good causes. The case study will use Glastonbury Festival as a focus for the legal, local government and environmental pressures that influence corporate behaviour and promote CSR.
Growth Through Metamorphosing
Authors: Gaio Loris , Rossi Alessandro , Zaninotto Enrico
Published: February 2020

One of the central concerns of the literature studying firms’ growth is the need for understanding the rationale underlying the growth process from the company perspective. The appearance of novel patterns of firms’ growth is linked to the emergence of new paradigms for the organization of industrial and manufacturing processes (that is, industrial revolution). The paper discusses evidence from a sample of fast-growing large companies taken from the Fortune 500 ranking. Results show patterns of firms’ growth more in line with traditional sectors which are fueled by scale and scope economies, and other patterns, observed more often in the case of high-tech “new economy” companies, which are instead fueled by network effects and platformization strategies. We label the latter phenomenon “metamorphosing,” a pattern of growth characterized by a constant reshaping of horizontal and vertical boundaries by the firm which aims at taking advantage of market opportunities by exploiting its keystone position in platform-based business.

Innovation is creating robots and computers that are able to perform many tasks previously accomplished by man. The place occupied by men in the job field will shrink. The current organization and the existence of many jobs are in danger. In the article we discuss the treats and opportunities of using ICT in business and the impact on business models and on the human’s job. Through a survey on Italian business context we observe the awareness of the people directly involved in decision making and in designing future work in the firms. The consciousness of the people on the effects of the diffusion of ICT matches with the opportunities for doing business. How to find the right equilibrium between the two perspectives?

Published: February 2020

The paper analyzes the Italian auto industry investments in Industry 4.0 technologies and firms’ perceived risks, constraints and limits to new technologies adoption. Results show that firms 4.0 are those at the higher level of the supply pyramid and closer to the final market, and are among the most innovative, dynamic and performing companies. Particularly firms invested to improve the Production, Quality, Logistics and Maintenance areas. The study also analyzes the relevance of the Italian Government’s plan for sustaining innovative investments and overall the main risks and constraints that could hinder the activation of Industry 4.0 initiatives in this setting.
Intervention Under Inflation Targeting--When Could It Make Sense?
Authors: Hofman David , Chamon Marcos , Deb Pragyan , Harjes Thomas , Rawat Umang , Yamamoto Itaru
Published: February 2020

We investigate the motives inflation-targeting central banks in emerging markets may have for intervening in foreign exchange markets and evaluate the case for such interventions based on the existing literature. Our findings suggest that the rationale for interventions depends on initial conditions and country-specific circumstances. The case is strongest in the presence of large currency mismatches or underdeveloped markets. While interventions can have benefits in the short-term, sustained over time they could entrench unfavorable initial conditions, though more work is needed to establish this empirically. A first effort to measure the cost of interventions to the credibility of policy frameworks suggests that the negative impact may be smaller than often assumed—at least for the set of more sophisticated inflation-targeting emerging-market central banks considered here.
Rwanda

Published: February 2020

Growth continues to outpace expectations. 2019 H1 growth was 10.3 percent y/y, fueled by private and public construction. Inflation rose at a slightly slower pace than anticipated in the first half of 2019, and 12-month average inflation was below the MPCC band from June-August this year. Lower-than-anticipated donor disbursements and higher execution of externally-financed deficit spending resulted in a higher-than-expected FY18/19 fiscal deficit, financed by a higher float and spending adjustment. Strong uptake of longer-term sovereign bond and an increased float led to domestic liquidity pressures in July-September, prompting greater activity on the interbank market and liquidity injections by the central bank. The trade deficit increased slightly more than expected in the first three quarters of 2019, due to adverse terms of trade and strong capital imports. This was largely offset by an improvement in services, largely reflecting strong performance of RwandAir. The RWF had depreciated by 4.7 percent at end-October y/y, and international reserves remain adequate.
Characterization of aerosol particles at Cabo Verde close to sea level and at the cloud level – Part 1: Particle number size distribution, cloud condensation nuclei and their origins

Published: February 2020

Abstract. In the framework of the MarParCloud (Marine biological production, organic aerosol particles and marine clouds: a Process Chain) project, measurements were carried out on the islands of Cabo Verde (a.k.a. Cape Verde) to investigate the abundance, properties and sources of aerosol particles in general, and cloud condensation nuclei (CCN) in particular, both close to sea level and at the cloud level. A thorough comparison of particle number concentration (PNC), particle number size distribution (PNSD) and CCN number concentration (NCCN) at the Cape Verde Atmospheric Observatory (CVAO, sea-level station) and Monte Verde (MV, cloud-level station) reveals that during times without clouds the aerosols at CVAO and MV are similar and the boundary layer is generally well mixed. Therefore, data obtained at CVAO can be used to describe the aerosol particles at cloud level. Cloud events were observed at MV during roughly 58 % of the time, and during these events a large fraction of particles was activated to cloud droplets. A trimodal parameterization method was deployed to characterize PNC at CVAO. Based on number concentrations in different aerosol modes, four well-separable types of PNSDs were found, which were named the marine type, mixture type, dust type1 and dust type2. Aerosol particles differ depending on their origins. When the air masses came from the Atlantic Ocean, sea spray can be assumed to be one source for particles besides new particle formation. For these air masses, PNSDs featured the lowest number concentration in Aitken, accumulation and coarse modes. Particle number concentrations for sea spray aerosol (SSA, i.e., the coarse mode for these air masses) accounted for about 3.7 % of NCCN,0.30 % (CCN number concentration at 0.30 % supersaturation) and about 1.1 % to 4.4 % of Ntotal (total particle number concentration). When the air masses came from the Sahara, we observed enhanced Aitken, accumulation and coarse mode particle number concentrations and overall increased NCCN; NCCN,0.30 % during the strongest observed dust periods is about 2.5 times higher than that during marine periods. However, the particle hygroscopicity parameter κ for these two most different periods shows no significant difference and is generally similar, independent of air mass. Overall, κ averaged 0.28, suggesting the presence of organic material in particles. This is consistent with previous model work and field measurements. There is a slight increase in κ with increasing particle size, indicating the addition of soluble, likely inorganic, material during cloud processing.
Synergistic enhancement of urban haze by nitrate uptake into
transported hygroscopic particles in the Asian continental outflow
Authors: Seo Jihoon , Lim Yong Bin , Youn Daeok , Kim Jin Young , Jin Hyoun Cher
Published: February 2020

Abstract. Haze pollution is affected by local air pollutants, regional transport of background particles and precursors, atmospheric chemistry related to secondary aerosol formation, and meteorological conditions conducive to the physical, dynamical, and chemical processes. In the large, populated and industrialized areas like the Asian continental outflow region, the combination of regional transport and local stagnant often exacerbates urban haze pollution. However, the detailed chemical processes underlying the enhancement of urban haze induced by the combined effect of local emissions and transported remote pollutants are still unclear. Here, we demonstrate an important role of transported hygroscopic particles in increasing local inorganic aerosols, by studying the chemical composition of PM2.5 collected between October 2012 and June 2014 in Seoul, a South Korean megacity in the Asian continental outflow region, using the ISORROPIA II thermodynamic model. Measured PM2.5 group under the condition of regional transport from the upwind source areas in China was higher in mass concentration and richer in secondary inorganic aerosol (SIA) species and aerosol liquid water (ALW) compared to that under the non-transport condition. The SIA and ALW were both increased, particularly in cases with high PM2.5 levels, and this indicates inorganic species as a major driver of hygroscopicity. We conclude that the urban haze pollution in the continental outflow region like Seoul, particularly during the cold season, can be exacerbated by ALW in the transported particles, which enhances the nitrate partitioning into the particle phase in NOx− and NH3-rich urban areas. This study reveals the synergistic effect of remote and local sources on the urban haze pollution in the downwind region and provides insight into the nonlinearity of domestic and foreign contributions to receptor PM2.5 concentrations in the numerical air quality models.
Using passive and active observations at microwave and sub-millimetre wavelengths to constrain ice particle models
Authors: Ekelund Robin , Eriksson Patrick , Pfreundschuh Simon
Published: February 2020

Abstract. Satellite microwave remote sensing is an important tool for determining the distribution of atmospheric ice globally. The upcoming Ice Cloud Imager (ICI) will provide unprecedented measurements at sub-millimetre frequencies, employing channels up to 664 GHz. However, the utilization of such measurements requires detailed data on how individual ice particles scatter and absorb radiation, i.e. single scattering data. Several single scattering databases are currently available, with the one by Eriksson et al. (2018) specifically tailored to ICI. This study attempts to validate and constrain the large set of particle models available in this database to a smaller and more manageable set. A combined active and passive model framework is developed and employed, which converts CloudSat observations to simulated brightness temperatures (TBs) measured by the Global Precipitation Measurement (GPM) Microwave Imager (GMI) and ICI. Simulations covering about 1 month in the tropical Pacific Ocean are performed, assuming different microphysical settings realized as combinations of the particle model and particle size distribution (PSD). Firstly, it is found that when the CloudSat inversions and the passive forward model are considered separately, the assumed particle model and PSD have a considerable impact on both radar-retrieved ice water content (IWC) and simulated TBs. Conversely, when the combined active and passive framework is employed instead, the uncertainty due to the assumed particle model is significantly reduced. Furthermore, simulated TBs for almost all the tested microphysical combinations, from a statistical point of view, agree well with GMI measurements (166, 186.31, and 190.31 GHz), indicating the robustness of the simulations. However, it is difficult to identify a particle model that outperforms any other. One aggregate particle model, composed of columns, yields marginally better agreement with GMI compared to the other particles, mainly for the most severe cases of deep convection. Of the tested PSDs, the one by McFarquhar and Heymsfield (1997) is found to give the best overall agreement with GMI and also yields radar dBZ–IWC relationships closely matching measurements by Protat et al. (2016). Only one particle, modelled as an air–ice mixture spheroid, performs poorly overall. On the other hand, simulations at the higher ICI frequencies (328.65, 334.65, and 668.2 GHz) show significantly higher sensitivity to the assumed particle model. This study thus points to the potential use of combined ICI and 94 GHz radar measurements to constrain ice hydrometeor properties in radiative transfer (RT) using the method demonstrated in this paper.

Seasonal variability of the circulation in the Arabian Sea at intermediate depth and its link to the Oxygen Minimum Zone
Authors: Schmidt Henrike , Czeschel Rena , Visbeck Martin
Published: February 2020

Abstract. Oxygen minimum zones (OMZs) in the open ocean occur below the surface in regions of weak ventilation and high biological productivity. Very low levels of dissolved oxygen affect marine life and alter biogeochemical cycles. One of the most intense but least understood OMZs in the world ocean is located in the Arabian Sea in a depth range between 300 to 1000 m. An improved understanding of the physical processes that have an impact on the OMZ in the Arabian Sea is necessary for a reliable assessment of its current state and future development. This study uses a combination of observational data as well as reanalysis velocity fields from the ocean model HYCOM (Hybrid Coordinate Ocean Model) to investigate the advective pathways of Lagrangian particles into the Arabian Sea OMZ at intermediate depths. In the eastern basin, the OMZ is strongest during winter monsoon with a core thickness of 1000 m depth and oxygen values of less than 5 μmol/kg. The minimum of oxygen concentration might be favored by a maximum advection of Lagrangian particles that follows the main advective pathway along the perimeter of the basin into the eastern basin of the Arabian Sea during winter monsoon. These Lagrangian particles pass regions of high primary production and respiration contributing to a transport of low oxygenated water into the eastern part of the OMZ. The maximum of oxygen concentration in the western basin of the Arabian Sea in May coincides with a maximum southward advection of particles along the western boundary during spring intermonsoon supplying the western core of the OMZ with higher oxygenated water. The maximum of oxygen concentration in the eastern basin of the Arabian Sea in May might be associated with the northward inflow of Lagrangian particles across 10° N into the Arabian Sea which is highest during spring intermonsoon. The Red Sea outflow of advective particles into the western and eastern basin starts during the summer monsoon associated with the northeastward current during the summer monsoon. Whereas particles from the Persian Gulf advect over the whole year. As the weak seasonal cycle of oxygen concentration in the eastern and western basin can be explained by seasonal changing advective pathways at intermediate depths into the ASOMZ, the simplified backward trajectory approach seems to be a good method for prediction of the seasonality of advective pathways of Lagrangian particles into the ASOMZ.
Machine learning and soil sciences: a review aided by machine learning tools
Authors: Padarian José , Minasny Budiman , McBratney Alex B.
Published: February 2020

Abstract. The application of machine learning (ML) techniques in various fields of science has increased rapidly, especially in the last 10 years. The increasing availability of soil data that can be efficiently acquired remotely and proximally, and freely available open-source algorithms, have led to an accelerated adoption of ML techniques to analyse soil data. Given the large number of publications, it is an impossible task to manually review all papers on the application of ML in soil science without narrowing down a narrative of ML application in a specific research question. This paper aims to provide a comprehensive review of the application of ML techniques in soil science aided by a ML algorithm (latent Dirichlet allocation) to find patterns in a large collection of text corpora. The objective is to gain insight into publications of ML applications in soil science and to discuss the research gaps in this topic. We found that (a) there is an increasing usage of ML methods in soil sciences, mostly concentrated in developed countries,
(b) the reviewed publications can be grouped into 12 topics, namely remote sensing, soil organic carbon, water, contamination, methods (ensembles), erosion and parent material, methods (NN, neural networks, SVM, support vector machines), spectroscopy, modelling (classes), crops, physical, and modelling (continuous),
and (c) advanced ML methods usually perform better than simpler approaches thanks to their capability to capture non-linear relationships.
From these findings, we found research gaps, in particular, about the precautions that should be taken (parsimony) to avoid overfitting, and that the interpretability of the ML models is an important aspect to consider when applying advanced ML methods in order to improve our knowledge and understanding of soil. We foresee that a large number of studies will focus on the latter topic.
Fatigue lifetime calculation of wind turbine blade bearings considering blade-dependent load distribution
Authors: Menck Oliver , Stammler Matthias , Schleich Florian
Published: February 2020

Abstract. Rotating bearings are some of the most commonly employed machine elements. As such, they are well-understood and thoroughly researched pieces of technology. Fatigue lifetime calculation is internationally standardized through ISO 281 which is based on the assumption that loads act on a bearing under constant rotation. Blade bearings of wind turbines do not conform to this assumption, since their movement typically consists of small, repetitive oscillations. Moreover, their load distribution differs considerably over the bearing circumference, a load case for which ISO 281 refers to ISO 16281 and which requires detailed simulations of the bearing to be sufficiently precise. Aside from ISO 16281, the NREL DG03, a guideline for pitch and yaw bearing lifetime, lists two methods for incorporating bearing loads into the fatigue life calculation. This paper compares all three methods. Load distributions in the bearing are simulated and interpolated by means of a novel approach. The method from NREL DG03 which requires the least computational effort is shown to result in a much higher lifetime than the other two, which are based on internal load distributions of the bearing. The two latter methods are shown to produce very similar results. An adjustment is proposed for increasing the accuracy of that lifetime calculation method which requires the least computational effort in order to resemble the other two more closely.

Las representaciones del indio en la era del descubrimiento y conquista de las Indias : el advenimiento de un concepto
Authors: Moreno Reséndiz Gerson
Published: February 2020

La palabra "indio" se desplazó del ámbito geográfico y económico hacia el ámbito de los saberes más altos en la cultura occidental del siglo xvi, el derecho y la teología, como un concepto fundamental dentro de la política. Hacia los primeros años de la conquista de América, el indio se convirtió en sujeto de lucha política, así certificado en los tratados, crónicas y documentos de la época. El indio se convirtió en concepto debido a que los diferentes grupos sociales comenzaron a luchar por constituir el verdadero ser del indio, pero también y al mismo tiempo, sobre su semántica se conformaron historias que harían referencia a recuerdos y expectativas. Así lo demuestran los diferentes escritos, y uno de los más representativos de todos, fue la pugna que sostuvieron en Valladolid Juan Ginés de Sepúlveda y Bartolomé de las Casas
Los Niveles, tendencias, orígenes y destinos de la migración interna de Honduras, 1988 - 2013
Authors: Flores Fonseca Manuel Antonio
Published: February 2020

La migración es el desplazamiento con traslado de residencia de las personas desde un lugar de origen o de partida hacia a un lugar de destino o de llegada, que implica atravesar los límites de una división geográfica (UIECP y CELADE, 1985). Es un componente de la dinámica demográfica junto a la fecundidad y mortalidad, que contribuye doblemente a través de las entradas con la inmigración y con las salidas a través de la emigración. En las migraciones internas se incluye los desplazamientos de las personas que atraviesan los límites geográficos como las Divisiones Administrativas Mayores (DAM) y las Divisiones Administrativas Menores (DAME) que, si bien se compensan los desplazamientos de manera nacional, permite estimar los volúmenes, flujos, proporciones, saldos, tasas y características de la migración absoluta o reciente. El objetivo de este artículo es presentar, a manera de actualización, las principales niveles, tendencias y preferencias migratorias internas en Honduras en el periodo 1988-2013, medido a través de su cuantía y magnitud relativa, volúmenes, proporciones, saldos, tasas, flujos, lugares de atracción y expulsión, así como las nuevas configuraciones que están ocurriendo en los movimientos de las personas. La fuente de datos utilizada son los Censos de Población y Vivienda de Honduras (CNPV) de 1950 al 2013, en mayor medida tres, de los últimos veinticinco años. Los censos hondureños antes de 1974 utilizaron la modalidad de facto o de hecho, a partir de ese año han usado la modalidad de yure o de derecho e incluso los últimos dos han utilizado el concepto de hogar unidad doméstica. Esta investigación, con carácter descriptivo, pretende estudiar el fenómeno migratorio interno partiendo de datos censales que se generan de las bases de acceso abierto para construir o utilizar las matrices de migración a nivel de DAM (departamento) y DAME (municipio), tanto de la migración absoluta y reciente. Se utilizan tres preguntas básicas de los cuestionarios censales: lugar de nacimiento para la matriz de migración absoluta y lugar de residencia cinco años antes del censo para construir la matriz de migración reciente y, lugar de empadronamiento, para ambas matrices.

Comprehensive Review of Rock Climbing Injuries
Authors: Cole Keegan P. , Uhl Richard L. , Rosenbaum Andrew J.
Published: February 2020

Increasing numbers of people are participating in the sport of rock climbing, and its growth is expected to continue with the sport's Olympic debut in 2020. Extreme loading of the upper extremities, contorted positioning of the lower extremities, rockfall, and falling from height create an elevated and diverse injury potential that is affected by experience level and quantity of participation. Injuries vary from acute traumatic injuries to chronic overuse injuries. Unique sport-specific injuries to the flexor tendon pulley system exist, but the remaining musculoskeletal system is not exempt from injury. Orthopaedic evaluation and surgery is frequently required. Understanding the sport of rock climbing and its injury patterns, treatments, and prevention is necessary to diagnose, manage, and counsel the rock-climbing athlete.
Prophylaxis for Pediatric Venous Thromboembolism: Current Status and Changes Across Pediatric Orthopaedic Society of North America From 2011

Published: February 2020

Introduction:

Pediatric venous thromboembolism (VTE) is a concern for orthopaedic surgeons. We sought to query the Pediatric Orthopaedic Society of North America (POSNA) members on current VTE prophylaxis practice and compare those results with those of a previous survey (2011).

Methods:

A 35-question survey was emailed to all active and candidate POSNA members. The survey consisted of questions on personal and practice demographics; knowledge and implementation of various VTE prophylaxis protocols, mechanical and chemical VTE prophylaxis agents, and risk factors; and utilization of scenarios VTE prophylaxis agents for various clinical scenarios. One- and two-way frequency tables were constructed comparing results from the current survey and those of the 2011 survey.

Results:

Two hundred thirty-nine surveys were completed (18% respondent rate), with most respondents from an academic/university practice reporting one or two partners (>60%). Half were in practice ≥15 years, and >90% reported an almost exclusive pediatric practice. One-third of the respondents reported familiarity with their institution-defined VTE prophylaxis protocol, and 20% were aware of an institutionally driven age at which all patients receive VTE prophylaxis. The most frequently recognized risk factors to guide VTE prophylaxis were oral contraceptive use, positive family history, and obesity. Respondents indicated a similar frequency of use of a VTE prophylaxis agent (either mechanical or chemical) for spinal fusion, hip reconstruction, and trauma (60% to 65%), with lower frequency for neuromuscular surgery (34%) (P< 0.001). One hundred thirty-seven respondents had a patient sustain a deep vein thrombosis, and 66 had a patient sustain a pulmonary embolism. Compared with responses from 2011, only 20 more respondents reported familiarity with their institution VTE prophylaxis protocol (75 versus 55). In 2018, aspirin was used more frequently than in 2011 (52% versus 19%;P< 0.0001) and enoxaparin was used less frequently (20% versus 41%;P< 0.0001).

Discussion:

Over the past 7 years since the first POSNA survey on VTE prophylaxis, most POSNA members are still unaware of their institution specific VTE prophylaxis protocol. Most respondents agree that either mechanical or chemical VTE prophylaxis should be used for spinal fusion, hip reconstruction, and trauma. The use of aspirin as an agent of chemical VTE prophylaxis has increased since 2011.

Published: February 2020

Introduction: Circumcision is considered the most common surgical procedure in the world. We aimed to compare the length of mucosal cuff after circumcision in patients with and without a complaint of premature ejaculation (PE).

Methods: Sexually active patients without erectile dysfunction that presented to the urology polyclinic between March 2018 and June 2018 were included in this multicentered, prospective study. The circumcision age of the patients, the person who performed the procedure (surgeon, non-surgeon), penile length, and dorsal and ventral penile measurements were recorded and compared between patients with and without PE.

Results: A total of 208 patients were included in the study. The mean circumcision age of the patients was 5.7±4.2 years, and the mean dorsal and mucosal size was 15.02±4.58 mm and 16.31±4.92 mm, respectively. PE was present in 106 of the participants. There was no statistically significant difference between the PE and non-PE groups in terms of the person who performed the procedure (surgeon, non-surgeon). However, the patients with PE had statistically significantly longer dorsal and ventral mucosal measurements compared to those without PE (p<0.001).

Conclusions: We think that the dorsal and ventral lengths of mucosal tissue left behind after circumcision is a risk factor for PE. Therefore, special attention should be paid not to leave redundant dorsal and ventral mucosal tissue during this procedure.

Authors: Parvin Murshida
Published: February 2020

With the innovation of technology, the nature of learning and teaching English as a Foreign Language (EFL) has been changed, and instead of traditional learning and teaching, e-learning has emerged as a new way to meet the demands of the ‘iGeneration’ who can easily roam around the knowledge domain just with a smartphone at anytime from anywhere. This research aims to find out the challenges of e-language learning that will help establish a more sophisticated Virtual Learning Environment (VLE) by implementing the latest version of the Learning Management System (LMS). E-learning is ‘constructive learning’ or ‘self-regulated learning’ where the learners work as ‘knowledge generators’ and teachers as ‘facilitators’ and so, the learning should be accomplished in a platform that ensures interaction, communication, and collaboration. This research will be provocative of establishing such an environment where online foreign language learners and instructors can adapt easily to the new pedagogical approach to learning for successfully attaining the target learning outcomes. A survey was conducted at the department of English, Najran University (Girls’ section), the Kingdom of Saudi Arabia, and the findings show the necessity of improving teachers’ efficiency in selecting e-learning tools to design learning materials and contents of the course considering cultural context and the modern-day learners’ capacity as well as the goal. It also discusses various implications regarding the need for e-language learners’ skill development that vigorously affects the learning process. The paper finally recommends some possible steps that can be adopted by a university for the successful implementation of e-learning to widen the realm of knowledge for the learners of English as Foreign Language (EFL).
Postmodern Political Discourse: A Thematic and Linguistic Analysis of Mandela’s Long Walk to Freedom
Authors: Muhammad Mukhtiar , Hashmi Farheen Ahmed
Published: February 2020

The Postmodern wave of democratization and the emphasis on democratic values and right to expression make it imperative that the political discourse be studied with more and full attention. In this regard, one genre that is almost totally ignored in Pakistani context and little attention has been paid to it even at the global level, is autobiography. Autobiography is a special kind of composition in which the author gives a picture of the evolution of the self and its relation with the external world throughout this evolutionary process. The famous political autobiography Long Walk to Freedom by Nelson Mandela is, therefore, selected as the basic unit of analysis. Through content analysis different topics are separated from the original text. These topics are then grouped under different categories of van Dijk’s theory of Political Discourse Analysis (PDA). The exploration and analysis of linguistic devices are also carried out. Besides Van Dijk’s PDA, Huckin’s approach to text and Corpus Linguistics’ quantitative methodology aided the systematic in-depth analysis. Methods of both qualitative and quantitative research have been utilized for this study as the researchers believe that quantification of data along with qualitative description produce reliable results. Findings revealed various linguistic devices are used in abundance. Amongst the most prominent ones are the unique and effective use of the year-statistics, language of the minority regime, Afrikaans, Trilingual combination, dramatic language and listing or cluster of three to stress certain themes like racial discrimination, inequality, poverty, parties, law, justice, separation and history.

The present work has as focus of discussion the relation school-city-families.Having as a unit of analysis the maintenance of a blumenauense catholic confessional school as a tradition and reference in the city scenario from its installation in the nineteenth century until the end of the twentieth century, this text seeks to explore one of the research clippings that investigated in thesis. from doctorate to triad mothers, school and city, specifically addressing the interaction of mothers with the school, regarding the selection and maintenance of their sons and daughters in this school.Using sociological categories such as habitus and tradition, this qualitative approach study explores the ways of being, feeling, acting and thinking of women and mothers, articulated in feelings of belonging that constitute an organizational network, not homogeneous, but amalgamated with manifestations. cultural features produced by sectors that idealized the school as the best, the most traditional, the reference school.It is a configurational study, under the analytical perspective of Norbert Elias. As a data collection instrument, we used interviews and document analysis.From the analysis of the obtained data, it can be affirmed that the innovations or curriculum alterations were not the result of the interaction school and families. The innovations resulted from external pressures, learning theories, hegemonic discourses conveyed by the pedagogical fad of the time.Because theschool is a reference, it could not fail to live up to the social and pedagogical demands that the times of the redemocratization of the country and the profusion of the knowledge society demanded from school processes.
