ANALISIS KEKUATAN BANGUNAN TERHADAP GAYA GEMPA DENGAN METODE PUSHOVER STUDI KASUS GEDUNG ASRAMA PUSDIKLAT PPATK, DEPOK
Authors: Tatya Putri Utami  , Niken Warastuti
Published: July 2019

Indonesia is an archipelago country located at a meeting of three tectonic plates so that Indonesia has the potential to experience an earthquake. As a result of the earthquake many buildings are damaged building structures. When an earthquake happens, the building is expected to be able to accept a certain level of earthquake force without significant damage to the structure or if the collapsing structures must be able to give non-linear behavior in the postelasticconditions so that the building's safety level against earthquake and safety of the occupants is more secure. The Pusdiklat PPATK boarding house, Depok is a building which in its development planning is expected to be able to accept the earthquake force and behave non-linearly. But this dormitory building does not yet have data on building resistance to earthquake forces. Therefore it is necessary to analyze this building by using one method of building strength analysis to earthquake forces that is pushover method. This analysis is done using SAP2000 program. The conclusion of the analysis shows that the greater the force (base force) given the greater the displacement that occurs in the building. The maximum earthquake load that the building can accept is 730,383 kN. Based on the ATC-40 performance limit the building is at the level of IO, indicating that the building is safe to use during an earthquake.

Rapid urban development demands a lot of infrastructure development. The development aims to support the activities of urban communities. Many research has been done on the structure, but the assessment of the visual quality of these structures is still very rarely done, especially in Indonesia. Flyovers are one of the structures that are often present in cities to solve congestion problems. Jakarta as the capital city, has many of these structures. Unfortunately, unwittingly adding structures can affect the visual quality of the surrounding environment. There are many ways to beautify these structures such as by adding plants, giving ornaments in the form of reliefs, to painting with mural art. The purpose of this article is to evaluate the visual quality of flyover structures. The methods used in this article include scenic beauty estimation (SBE), semantic differential (SD), factor analysis, multidimensional scaling, and Kendall’s W. The results obtained are different levels of visual quality of flyover structures based on the appearance of complementary ornaments. Based on SBE analysis, the structure with reliefs that were not colored showed poor visual quality with an SBE value of -46,483. High visual quality based on SBE analysis, namely the structure with the softscape element in the form of landscape plants (89,777). The impression caused by the structure with softscape elements in the form of landscape plants is considered shadier and attractive.

False memory refers to the experience of thinking when we remember something that actually did not really happen. The major problem with false memory is the possibility to make someone may easily be led through misinformation. The current research assessed the difference between two types of question on preschoolers' false memory. This study used an experimental design with 76 participants of preschoolers (53.9% male and 46.1% female, 5-6 years old) who divided into two experimental groups. First group was given a neutral question, while the second group was given a misleading question. In this experiment, the participants were instructed to watch a video, then, one recognition test will be held immediately. In recognition test, participants were showed some pictures and questions about one event. The chi-square analysis shows that there is a significant difference between two types of question (0.04<0.05) the value of Chi-Square was 11.647. Based on these results, it implies that misleading questions might raise more false memory than neutral questions.
Gambaran Pengetahuan, Sikap, dan Praktik Perilaku Mahasiswa terhadap HIV/AIDS dan ODHA (Orang dengan HIV/AIDS)

Published: July 2019

Undergraduate students in adolescence and young adulthood period are sexually productive. It is crucial to discover their knowledge, attitude, and practice (KAP) towards HIV/AIDS since the highest HIV infection in Indonesia until 2016 is between those ages. The survey was conducted in Indonesia between November-December 2015. Data was collected using online structured KAP questionnaire to 350 undergraduate students (aged 18-23 years old) in Universitas Indonesia and analyzed with descriptive statistic. The KAP questionnaire used was adapted from Mulu, Abera, and Yinner (2014). Results shown that most participants answered correctly in knowledge items, but most of them still didn't know that HIV and AIDS are two different things, and they think that HIV can be infected through sharing foods, exchanging clothes and toilets with PLWH (People Living with HIV). Most participants have a positive attitude towards HIV/AIDS, but they have a negative attitude regarding on using condom while having sex as an affront to the couple, and disagreeing to live together with PLWH. Regarding on the practice, as much as 76 participants who have had sex ever had a risky sexual behavior but never had VCT (Voluntary Counseling & Testing), while the rest of participants who never had sex mostly have seen a condom but didn't feel comfortable to hold it. Knowledge towards HIV/AIDS was quite sufficient, the attitude was fair enough, but the practice for the participants who have had sex needed attention more. The results also might indicate stigma towards HIV/AIDS in Indonesia still exists because HIV is considered as an easily infected disease.

Nostalgia originii la Andreï Makine, Testamentul francez și Sorin Titel, Țara îndepărtată / The nostalgia of the place of birth in Andrei Makine's French Will and in Sorin Titel's The Aloof Country
Authors: Pîrvu Simina
Published: July 2019

In the Middle Ages, exile meant expatriation, the prolonged absence from the native lands, one can say that a person is in exile when it is not possible to return back home. Exile involves unsettlement; the expatriated suffers from nostalgia and tries to recover his origin, the center, his home. Thinking about the past involves an idealized representation of lived history, which may have the effect of a mythical evocation of the past.

               The nostalgia is one of the central ideas of the novels of the Russian writer Andreï Makine, who has hardly built his identity as a Russian writer of French, his literary beginnings being not simple. The theme of the nostalgia and the parallel between two different worlds are constantly found in Makine's novels, and in The French Will it gets a special note. Andreï Makine says in interviews that he chose to write in French, but his country of origin is always in his soul.               Another writer – Romanian this time – in whose novels we find the nostalgia of origins is Sorin Titel, who reveals an unusual world, Banat, where the writer was born. The estrangement from Banat has beneficial consequences in almost all respects. Established in Bucharest, the author has the nostalgia of Banat and transforms it into an epic projection, reinvents Banat. The removal from the places of origin, the distancing, the alienation, are mandatory conditions of the pilgrimage to himself, for only by being far from Banat he could reinvent him, using the memories of his childhood. Even the title of his first book with which he begins the recuperation is enlightening: The Aloof Country, signifying both the Banat, geographically, and the age of childhood, at a symbolic level.               This is the case with the two writers, Andreï Makine and Sorin Titel, writers who being far away from their native places, have fictionally translated what they feel for home - Russia and Banat.

Procesos creativos en el aula para la enseñanza de la composición musical mediante géneros mestizos ecuatorianos
Authors: Velasco Carvajal Pablo Fernando
Published: July 2019

La composición constituye una disciplina fundamental del arte musical, la misma que ha tenido un importante desarrollo en los últimos años dentro de la educación musical en el Ecuador, por lo que resulta necesaria la utilización de procesos creativos en el aula, que estén basados en ritmos mestizos ecuatorianos que sirvan para la enseñanza de esta disciplina de manera formal. La enseñanza de la composición académica en el Ecuador se ha venido realizando a partir de contenidos pertenecientes a un contexto histórico-cultural europeo en su gran parte; por ende, considerando que ha transcurrido más de un siglo desde que se formalizó el estudio de la música académica en el país y que actualmente ya se dispone de un considerable número de obras creadas en el marco de nuestra realidad cultural ecuatoriana, aspiramos a que la aplicación de procesos creativos con un contexto propio de nuestra región, se convierta en un aporte para la enseñanza de la composición, teniendo en cuenta que hasta la fecha no existe un texto que recopile y sistematice recursos compositivos orientados a mostrarnos cómo usar estos adecuadamente, por lo que con este trabajo se pretende marcar un punto de partida para la realización de futuros trabajos para la enseñanza de la composición en el Ecuador.
Cómo incentivar el estudio del violín en niños y niñas de siete a diez años
Authors: Cajuste Triviño Luis Ramón
Published: July 2019

Este trabajo fue elaborado con base en mi experiencia como docente del nivel inicial de violín, en el Instituto de la Universidad Estatal de Guayaquil, en donde encontré algunas dificultades en las primeras etapas del aprendizaje del instrumento, lo que me llevó a consultar diferentes métodos y, con la experiencia de otros docentes de mi área, para encontrar dónde estaba el problema en cuanto a la desmotivación que sufren algunos niños cuando inician el estudio del violín, concordando con el mismo inconveniente. Por tal motivo, incluí en mi repertorio académico canciones didácticas infantiles que les eran familiares a mis alumnos y a sus compañeros de las mismas edades, lo que hizo que el aprendizaje sea más significativo, haciendo énfasis en la práctica del instrumento sin descuidar las técnicas y ejercicios de digitación que habitualmente se enseñan en todos los niveles, logrando un mejor rendimiento académico, mejor predisposición y estado emocional y aumento de auto estima, creando un ambiente de empatía entre el docente y el alumno durante el proceso de enseñanza y aprendizaje.

The advertisement call of the phytotelm-breeding Melanophryniscus xanthostomus (Anura: Bufonidae)
Authors: Mângia Sarah , Santana Diego José , Mariotto Lucas Ribeiro
Published: July 2019

Vocalizations are often useful for understanding taxonomic relationships among anuran species. Despite this usefulness, vocalizations are described in only nine of 29 in Melanophryniscus Gallardo, 1961. Here we describe the advertisement call of Melanophryniscusxanthostomus Baldo, Bornschein, Pie, Ribeiro, Firkowski & Morato, 2015 of a population from Serra Dona Francisca, municipality of Campo Alegre, state of Santa Catarina, Brazil. The advertisement call (of three males, total of 17 calls) comprises two segments (the first with short and single notes, followed by a multi-pulsed note), with a duration of 12.194–20.986 s, and dominant frequency of 3101–3618 Hz (first and second segments combined). The advertisement call of M.xanthostomus differs from its congeners mostly by the higher number of pulses in the second segment (294–1033; from 16 to 321 in the other Melanophryniscus species), except Melanophryniscuskrauczuki Baldo & Basso, 2004 (1018–1502 pulses in the second segment). This is the first described call of a phytotelm breeding Melanophryniscus, but it presents the same prototype (a compound call formed by two segments, the first composed of short notes followed by a long trill) of its congeners not-phytotelm breedings. This might indicate the advertisement call of Melanophryniscus as a conserved trait and thus can be considered diagnostic for the genus.
« On embellit mon corps pour l’exposer aux flammes, / et souvent on le peint de diverse couleur »
Authors: Rizzoni Nathalie
Published: July 2019

Objet usuel de la vie quotidienne en Europe au 18 e  siècle, l’écran à main avait pour fonction première de protéger de l’ardeur du feu le visage de celle ou de celui qui était assis auprès d’une cheminée. Alliant l’agréable à l’utile, ce rempart fragile se devait d’être également élégant. La mise en couleur de l’objet relève de cette fonction esthétique tout en servant à l’occasion un programme plus ambitieux : instruire et divertir ceux (adultes et enfants) qui le tenaient à hauteur des yeux. La couleur participe dans ce cadre d’un processus d’identification ou de décryptage à différents niveaux : repérer les écrans d’une même série thématique ; faciliter la lecture des cartes de géographie ; permettre l’identification des personnages d’un écran à l’autre sur les séries d’illustrations se rapportant à une même pièce de théâtre. Enfin, la couleur est une composante essentielle des merveilleux écrans nouveaux diffusés par Madame Dulac au début des années 1760.
Pour des couleurs plus solides ?
Authors: Martin Marguerite
Published: July 2019

Le secteur de la teinture connaît de profondes mutations à l’époque moderne en raison du recours croissant à de nouveaux colorants d’origine tropicale et européenne. Alors que l’administration française réaffirme en 1737 le principe d’une distinction réglementée pour les draps entre la teinture de qualité supérieure (le bon teint) et de qualité moindre (le petit teint), les teinturiers s’émancipent de ces règles et profitent de la diffusion des nouveaux colorants, en particulier de l’indigo, pour proposer des nuances plus solides sur des étoffes de qualité médiane. Ils s’adaptent ainsi à l’évolution du marché, marquée par l’élargissement de l’offre de textiles de qualité intermédiaire.
Pour une sculpture pittoresque
Authors: Champy-Vinas Cécilie
Published: July 2019

Il est couramment admis que la sculpture française du 18 e  siècle était presque exclusivement monochrome, l’absence de couleur devenant même dans la seconde partie du siècle, avec l’influence du retour à l’Antique, l’un des traits distinctifs de la sculpture par rapport à la peinture. À travers l’exemple de deux monuments réalisés par le sculpteur Jean-Baptiste Lemoyne pour l’église Saint-Louis-du-Louvre à Paris, aujourd’hui disparus, on montrera comment une conception « pittoresque » de la sculpture s’est maintenue en France jusqu’à la fin du 18 e  siècle – une conception dans la tradition du 17 e  siècle, qui privilégiait les effets de surface et de couleur pour créer de spectaculaires effets d’illusion.
La couleur de la peau dans le discours médical (1730-1770)
Authors: Linte Guillaume
Published: July 2019

Au 18 e  siècle, les discours sur l’origine et la diversité des couleurs de la peau se multiplient. Ceux-ci émanent d’acteurs variés : voyageurs, géographes, religieux, naturalistes, philosophes, etc. La question de la couleur de la peau s’intègre, le plus souvent, à une réflexion plus générale sur la diversité humaine. En s’appuyant sur ses propres méthodes et théories, la médecine propose une approche originale du sujet, plaçant au premier plan la compréhension des mécanismes en cause et la recherche du support de la pigmentation. Cependant, loin d’être unanime, le discours médical évolue et voit parfois s’affronter en son sein des conceptions radicalement opposées.
Châtiment et rédemption par la langue
Authors: De Santis Vincenzo
Published: July 2019

La Révolution suscite chez le philosophe et théosophe Louis-Claude de Saint-Martin des réflexions de nature très diversifiée, qui tiennent à la fois de la religion, de la morale, de la politique, et qui sont publiées en même temps qu’un large corpus d’ouvrages où spéculation mystique et études linguistiques s’entremêlent. La lecture du poème Le Crocodile (1792) et de la Lettre à un ami sur la Révolution Française (1794) – deux œuvres majeures du Philosophe Inconnu – montre le rapport existant entre ces différents domaines de sa pensée et révèle la signification eschatologique que l’auteur attribue à la fin de l’Ancien Régime.
The Effect of a Course in Nursing Ethics on the Relationship Between Ethical Choice and Ethical Action in Baccalaureate Nursing Students
Authors: Gaul Alice LeVeille
Published: July 2019

ABSTRACT

This study examined the effect of an ethics course on the variables of ethical choice and ethical action in baccalaureate nursing students. Data were collected from 17 students who were enrolled in a three-credit elective course in ethics and from 20 students who were matched for placement in the curriculum but who were not enrolled in the ethics course. The ethics course consisted of study of the major ethical principles and theories as well as guided ethical case analysis with emphasis on the role and responsibilities of the nurse. Ethical choice and ethical action were measured by Ketefian's Judgment About Nursing Decisions.

The variables of moral choice and moral action were positively correlated r = .87 (p < .001) in the students who were enrolled in the ethics course and they were negatively correlated at r = - .32 (p .34) in the students who were not enrolled in the ethics course. Overall scores of the two groups on both column A (Ethical Choice) and column B (Ethical Action) were not significantly different. The total scores of the ethics group were higher. The results of this study lend support to the inclusion of a course in ethics in nursing curricula. Continued research into this area should continue to be a high priority.
Multidisciplinary approach in the management of uterine intravenous leiomyomatosis with intracardiac extension: case report and review of literature
Authors: Marrone Gianluca , Crinò Francesca , Morsolini Marco , Caruso Settimo , Miraglia Roberto
Published: July 2019

Uterine intravenous leiomyomatosis is an uncommon tumor, usually arising from the uterus, with nodular masses which extend intravascularly over variable distances and may reach the inferior vena cava, right atrium, and pulmonary arteries. Early diagnosis and surgical intervention are crucial as intracardiac leiomyomatosis not only causes cardiac symptoms but may result in pulmonary embolism and sudden death. Complete tumor resection is key in disease management, thus rendering cardiac-extending uterine intravenous leiomyomatosis one of the most challenging conditions for surgical treatment. The use of interventional radiology procedures can facilitate the surgical approach. We report the case of a massive pelvic recurrence of uterine leiomyomatosis with intracardiac extension and pulmonary embolism, analyzing management and surgical outcomes, highlighting the role of interventional radiology during the therapeutic pathway. Nonetheless, there are currently very few data available concerning the use of interventional radiology procedures in the therapeutic strategy of uterine intravenous leiomyomatosis with intracardiac extension.

Authors: Ramón Ojeda Antonio A. , López Rivero Sarah
Published: July 2019

Las instalaciones para la práctica de deportes de invierno en las montañas españolas han contribuido a producir espacios turísticos asociados a las estaciones de esquí. El presente estudio aborda, a partir de diferentes clasificaciones del espacio turístico de montaña asociado a la práctica de deportes de invierno, una propuesta de clasificación del espacio turístico de nieve en España. Para ello se ha elaborado un inventario de las 33 estaciones pertenecientes a ATUDEM que incluye 28 centros de modalidad alpina y 5 de esquí nórdico. En primer lugar, se ha realizado una revisión bibliográfica, con especial atención a los intentos de clasificación de estos espacios llevados a cabo en el ámbito de los Alpes y también en España. Seguidamente, a partir del inventario extenso de las estaciones españolas y tras elaborar esquemas territoriales de cada caso con el fin de estudiar las relaciones geográficas entre componentes espaciales, se propone una clasificación del espacio turístico de nieve y se describen sus características principales. Las cuatro tipologías posibles son: 1. Espacios complejos polinucleares y polivalentes. Estaciones de esquí asociadas a complejos turísticos. 2. Espacios simples mononucleares y especializados que conforman estaciones aisladas con urbanización turística. 3. Espacios simples mononucleares y especializados que conforman estación aislada más hotel o inmueble de apartamentos turísticos. 4. Espacios simples mononucleares y especializados que conforman estación aislada sin alojamientos en el ámbito inmediato.
Quel développement professionnel pour des enseignants associés dans une formation de type recherche-action participative ?
Authors: Mattei-Mieusset Claire , Emond Geneviève , Boudreau Pierre
Published: July 2019

Cet article est issu d’une recherche internationale : PReParE-Eps, 2015-2018 (Belgique, Canada, États-Unis, France, Suisse), portant sur le développement des compétences des enseignants associés (EA) en Education Physique et Sportive (EPS), dans leur fonction d’accompagnement (Paul, 2009) d’un enseignant débutant. En contexte français, cinq EA bénéficient d’une formation de type « recherche-action participative » (RAP) (Chevalier et Buckles, 2013). La RAP, utilisée dans un but de développement professionnel, engage les participants dans toutes les étapes d’une telle formation tout en tenant compte des compétences déjà acquises et de leur autonomie comme professionnel. Les données se présentent sous la forme de discours oral et écrit des EA, en amont, pendant, et en aval du dispositif organisé en quatre journées réparties sur cinq mois. Nous caractérisons le processus de développement professionnel (Grosstephan, 2010 ; Jorro, 2014) de deux EA à partir de trois indicateurs : réflexivité, mobilisation d’outils conceptuels, construction d’un genre professionnel (Clot, 1999), dans quatre phases : insécurité, expérimentation, appropriation, consolidation (Boucher et Jenkins, 2004), tout en cernant les apports spécifiques d’une RAP dans cette dynamique.
Analysis of the Vision and Mission Statements in the Websites
Authors: Bezirgan Muammer
Published: July 2019

The purpose of the present study is to analyze the website-declared vision and mission statements of 149 five-star hotels in the largest cities of Turkey, Istanbul, Ankara, and Izmir, based on certain criteria. The outcomes of the research indicated that only 24% of the hotels had a mission statement and 21% had a vision statement. Hotels with the least number of statements were those in Istanbul (17%). It was determined that hotels provided highly limited information on the product/market area component in their mission statements (19%). Moreover, it was determined that although hotels fully reflected their basic ideology in vision statements, almost half of them (48%) failed to place an emphasis on the future in their statements.
Online Teaching and Learning in Higher Education Settings
Authors: Baran Mette L. , Jones Janice E.
Published: July 2019

This chapter intends to answer the question, “What are some guidelines for working effectively in virtual teams?” To further advance existing literature, the authors utilized a qualitative phenomenological approach with a randomly-sampled group of seven students who had completed master's-level education courses that were conducted in an online format at a private Midwestern University. Students were halfway through their course completion at the time of data collection. In addition, a random sample of one program administrator and four faculty members were interviewed. Specifically, students who enrolled in online Master's in Education courses are required to work in study teams to complete a certain portion of the course work. Study teams can often be difficult to navigate in person and with the added dimension that a virtual experience brings to developing trusting, successful working relationships, different working guidelines are needed. Findings revealed that managerial and social aspects of online learning and teaching were critical for online students' success.

Bovine leukemia virus (BLV) infection is a chronic viral infection of cattle and endemic in many countries, including Japan. Our previous study demonstrated that PGE2, a product of cyclooxygenase (COX) 2, suppresses Th1 responses in cattle and contributes to the progression of Johne disease, a chronic bacterial infection in cattle. However, little information is available on the association of PGE2 with chronic viral infection. Thus, we analyzed the changes in plasma PGE2 concentration during BLV infection and its effects on proviral load, viral gene transcription, Th1 responses, and disease progression. Both COX2 expression by PBMCs and plasma PGE2 concentration were higher in the infected cattle compared with uninfected cattle, and plasma PGE2 concentration was positively correlated with the proviral load. BLV Ag exposure also directly enhanced PGE2 production by PBMCs. Transcription of BLV genes was activated via PGE2 receptors EP2 and EP4, further suggesting that PGE2 contributes to disease progression. In contrast, inhibition of PGE2 production using a COX-2 inhibitor activated BLV-specific Th1 responses in vitro, as evidenced by enhanced T cell proliferation and Th1 cytokine production, and reduced BLV proviral load in vivo. Combined treatment with the COX-2 inhibitor meloxicam and anti-programmed death-ligand 1 Ab significantly reduced the BLV proviral load, suggesting a potential as a novel control method against BLV infection. Further studies using a larger number of animals are required to support the efficacy of this treatment for clinical application.
Using Control Redundancy for Power and Vibration Reduction on a Coaxial Rotor Helicopter at High Speeds
Authors: Jacobellis George , Gandhi Farhan , Floros Matthew
Published: July 2019

This study uses the Rotorcraft Comprehensive Analysis System (RCAS) to examine the effect of control redundancy on power and vibratory hub loads of a lift-offset coaxial rotor helicopter operating at 230 kt cruise speed. An aircraft nose-up pitch attitude of 3° resulted in very
low main rotor power (less than 10% of the total power), with the majority of the power consumption attributed to an efficient axial propeller. At this 3° pitch attitude, the rotor speed and differential lateral pitch, which are redundant controls, were parametrically varied, and low power
(LP) and low vibration (LV) states identified. The LP state (80% Nr and 3° differential lateral) required 3.5% lower power than the LV state (90% Nr and 0° differential lateral), but the latter had substantially lower 3/rev vibratory hub loads. The lower power in the LP state
is primarily due to reduced main rotor power on account of smaller drag on the advancing blade tip at lower rotor speeds. The rotor drag is comparable for the two states, but the LV state has larger drag contributions from the advancing side, whereas the LP state has larger contributions from
the reverse flow region (accounting for 14% of the total rotor drag) due to higher pitch on the retreating side and larger reverse flow velocities. Even so, the rotor drag accounts for under 30% of the total propulsor thrust requirement, with the fuselage (and hub) drag being the dominant
component. Rotor L/De values for the LP and LV states were 12.3 and 11.3, respectively.
Globalisation: The political dynamics
Authors: Schrire Robert A.
Published: July 2019

Globalisation is a multidimensional phenomenon and should be conceptualised as a process rather than an outcome. Economic, political, cultural and societal elements are involved in the complex set of interactions we can-define as globalisation. However, a key factor, which is frequently ignored is the importance of politics in shaping and guiding this process. For example economic liberalisation and deregulation, the form which economic globalisation has thus far taken, did not emerge from impersonal market and technological forces. Governments, especially those of the United States and Great Britain, followed explicit policies of currency controls relaxation, the reduction in trade barriers, and the retreat in the role of the state in the economy generally. Despite the power of the economic forces thus released, politics remains a key potential player and globalisation is not necessarily irreversible. Given the indeterminacy of the outcomes of globalisation, four alternative theories of the future are presented and analysed.
Sense of coherence, coping and burnout of pharmacists
Authors: Basson M. , Rothmann S.
Published: July 2019

People in almost any occupation could develop burnout. The objective of this research was to determine the relationship between sense of coherence, coping and burnout in a corporate pharmacy group. A cross-sectional survey design was used. The study population consisted of 67 pharmacists. The Maslach Burnout Inventory, Orientation to Life Questionnaire and COPE were administered. The results showed that sense of coherence is significantly related to emotional exhaustion, depersonalisation and personal accomplishment. Regarding coping strategies, mental disengagement was positively related to emotional exhaustion and depersonalisation, while positive reinterpretation and restraint coping were positively related to personal accomplishment. Sense of coherence and coping strategies explained 44 per cent, 35 per cent and 41 per cent of the variance in emotional exhaustion, depersonalisation and personal accomplishment respectively.
Examining the crises in the food sector of Nigerian agriculture
Authors: Ilorah Richard
Published: July 2019

Food output in Nigeria has deteriorated since the 1970s, whereas the population continues to grow. Consequently, the country experiences a fall in per capita food production. Grouping the country's food producers under four categories, this paper argues that production has remained a predominantly peasant affair, characterized by subsistency, inefficiency and low productivity. For a way forward out of the food crises, we introduce a theoretical model of the impact of policy mechanisms on agricultural output. We also look at the target group of the policy mechanisms. The paper concludes that to tackle the food crises, the country needs a radical approach to the problem, with emphasis on a total departure from its hitherto subsistence farming to a modem commercial farming.
The benefits of HIV/AIDS intervention in the workplace: A case study
Authors: Booysen F. Le R. , Molelekoa J.
Published: July 2019

Over the next ten years, as the AIDS epidemic takes its toll on the economically active population, employers will incur considerable costs. However, relatively inexpensive interventions, if implemented now, can yield substantial returns and save business considerable amounts of money. Thus, social responsibility can be argued to make economic sense. Worrying, though, is that there also appears to be a general apathy on the part of business, especially amongst small and medium-sized enterprises. A lot needs to be done to change the attitude of business and get business actively involved in the fight against HIV/AIDS. The private sector can and need to do its share in an integrated, coordinated response to HIV/AIDS, thus contributing to the initiatives on which the government, NGOs and communities have already embarked.
US trade and investment in Africa: What are the prospects for the 21st century?
Authors: Ekanem N. Frank
Published: July 2019

African countries considered in this study face many supply constraints and so lack the capacity to produce. Export promotion effort cannot be successful unless such constraints are removed. Transparency in governance, improvements in basic infrastructure and economic liberalization are some of the ways to remove such constraints. Direct private investment to accelerate economic expansion rather than exchange rate manipulations are needed before export promotion policy can be successful.
The integration of economics and the environment through incentives: An overview of the Costa Rican success story
Authors: Blignaut J. N. , Anderson H. J.
Published: July 2019

Conservation is often perceived as the responsibility of the landowners. If landowners fail to benefit from conservation, they inevitably view it as profit-eroding and it becomes less attractive than alternative land-use practices. Costa Rica has successfully internalised the benefits provided by forestry environmental services. Valuable lessons could be learnt from the Costa Rican experience in using economic incentives for environmental management.
Trade, environment and sustainable development: What changed in Doha
Authors: Wilson Jessica
Published: July 2019

Agenda 21, the blueprint for sustainable development, adopted at the Earth Summit in Rio de Janeiro in 1992, does not have a chapter dedicated to trade. Yet since 1992, trade has become increasingly important to democracy, human rights, women's rights, economic development, employment and the environment. "Trade and environment" has been identified by many governments and civil society organisations as an important policy issue in preparations for the World Summit on Sustainable Development. At the same time, environment has become a highly politicised word in the world inhabited by trade negotiators. The aim of this paper is to examine whether or not the inclusion of WTO environmental negotiations, as outlined in the Doha Ministerial Declaration, advances or retards sustainable development.
On the long-run interdependence of stock markets: A tale of correlations, autoregressions and decompositions
Authors: Moolman Elna , McCoskey Suzanne
Published: July 2019

It seems as if national stock markets within certain groups of countries, for example within Europe and Asia, are interdependent. But to what extent are stock markets between these groups interdependent? Is it still possible to diversify among these groups, or have globalization tied world markets together to such an extent that diversification is no longer feasible? In this study we use time series techniques to analyze the interdependence among four of the most important groups of economies, namely Europe, Latin America, Asia and the US. This will show whether it is still possible to diversify between the stock markets of these groups of economies, since stock markets within these groups seem to be interdependent to such an extent that diversification within these groups is no longer possible. On a methodological level, we compare the results of the OLS-VAR with an FM-VAR model, which is a more robust estimation procedure in the presence of non-stationary or cointegrated series.
Tax revenue as an automatic fiscal stabiliser: A South African perspective
Authors: Swanepoel A. S. , Schoeman N. J.
Published: July 2019

The many practical economic and political difficulties encountered in discretionary fiscal stabilisation policy highlight the potential benefits of allowing automatic fiscal stabilisers to operate over the cycle. This article investigates the relevance of tax revenue as an automatic fiscal stabiliser in the South African economy by an empirical analysis of its role and impact since the 1970s. The study finds that cyclical changes in tax revenue are relatively small and provide no significant evidence of automatic stabilisation; however, the potential of this tool as an effective automatic fiscal stabiliser in South Africa cannot be overlooked as results show a high correlation between the output gap and automatic stabiliser estimates. Automatic fiscal stabilisers were employed symmetrically over the cycle and results showed that automatic fiscal stabilisers became increasingly important towards the end of the sample period.

Abstract. High-temporal-resolution observations from satellites have a great potential
for studying the impact of biomass burning aerosols and clouds over the
south-east Atlantic Ocean (SEAO). This paper presents a method developed to
simultaneously retrieve aerosol and cloud properties in aerosol above-cloud
conditions from the geostationary instrument Meteosat Second
Generation/Spinning Enhanced Visible and Infrared Imager (MSG/SEVIRI). The
above-cloud aerosol optical thickness (AOT), the cloud optical thickness
(COT) and the cloud droplet effective radius (CER) are derived from the
spectral contrast and the magnitude of the signal measured in three channels
in the visible to shortwave infrared region. The impact of the absorption
from atmospheric gases on the satellite signal is corrected by applying
transmittances calculated using the water vapour profiles from a Met Office
forecast model. The sensitivity analysis shows that a 10 % error on the
humidity profile leads to an 18.5 % bias on the above-cloud AOT, which
highlights the importance of an accurate atmospheric correction scheme. In situ
measurements from the CLARIFY-2017 airborne field campaign are used to
constrain the aerosol size distribution and refractive index that is assumed
for the aforementioned retrieval algorithm. The sensitivities in the
retrieved AOT, COT and CER to the aerosol model assumptions are assessed.
Between 09:00 and 15:00 UTC, an uncertainty of 40 % is estimated on the
above-cloud AOT, which is dominated by the sensitivity of the retrieval to
the single-scattering albedo. The absorption AOT is less sensitive to the
aerosol assumptions with an uncertainty generally lower than 17 % between
09:00 and 15:00 UTC. Outside of that time range, as the scattering angle
decreases, the sensitivity of the AOT and the absorption AOT to the aerosol
model increases. The retrieved cloud properties are only weakly sensitive to
the aerosol model assumptions throughout the day, with biases lower than
6 % on the COT and 3 % on the CER. The stability of the retrieval over
time is analysed. For observations outside of the backscattering glory
region, the time series of the aerosol and cloud properties are physically
consistent, which confirms the ability of the retrieval to monitor the
temporal evolution of aerosol above-cloud events over the SEAO.
