Óscar Pérez (1981-2018): chronicle of a death foretold
Authors: Deneuville Allan
Published: November 2020

In this article, we propose the comparative study of two works that use videos of Venezuelan political opponent Óscar Pérez who was killed during a military raid. Romain Champalaune’s film (The Life and Death of Óscar Pérez) and the website of the British collective Forensic Architecture question us about the future of user-generated content and the place of the artist and the researcher in the society of hyper-production of texts and documents. After introducing the Perez case and presenting the works, we analyze the regime of proof and the idea of truth and the archive in the era of algorithmic governmentalities. Finally, we study how investigation and the collection of user-generated content allow for a shift in our power regimes through the implementation of counter-narration to that of the powers that be.

Published: November 2020

Pregnancy-induced pelvic girdle pain (PGP) and low back pain (LBP) is common in post-natal women's. We conducted the study to evaluate the effectiveness of a modified sacroiliac belt on pelvic girdle pain in post-natal women. A total of 26 post-natal women between the age group of 18-35 years were selected and randomized into Group 1(N=13) received conventional sacroiliac belt, conventional physiotherapy and Group 2 (n=13) received modified sacroiliac belt along with conventional physiotherapy. Pre-assessment of pelvic girdle was assessed by (Pelvic Girdle Pain Questionnaire) PGPQ, and low back pain was assessed by Roland Morris low back pain and disability questionnaire (RMQ) and Post-interventional assessment was taken for the same after three months. Intragroup statistical analysis for PGPQ revealed not significant in post-intervention for Group 1 where P-value 0.3023 and was extremely significant for Group 2 (P value<0.0001). At the same time, the Intergroup intervention analysis showed an extremely significant difference between Group 1and Group 2 (p< 0.0001). The study concluded that  Integrating Modified sacroiliac belt with conventional physiotherapy is more effective in reducing pelvic girdle pain in post-natal women with also benefiting to reduce the pregnancy-induced low back pain as compared to the conventional sacroiliac belt and conventional physiotherapy.

Published: November 2020

The new SARS-CoV-2 belonging to the coronaviruses family has caused a pandemic affecting millions of people around the world. This pandemic has been declared by the World Health Organization as an international public health emergency. Although several clinical trials involving a large number of drugs are currently underway, no treatment protocol for COVID-19 has been officially approved so far. Here we demonstrate through a search in the scientific literature that the traditional Moroccan pharmacopoeia, which includes more than 500 medicinal plants, is a fascinating and promising source for the research of natural molecules active against SARS-CoV-2. Multiple in-silico and in-vitro studies showed that some of the medicinal plants used by Moroccans for centuries possess inhibitory activity against SARS-CoV or SARS-CoV-2. These inhibitory activities are achieved through the different molecular mechanisms of virus penetration and replication, or indirectly through stimulation of immunity. Thus, the potential of plants, plant extracts and molecules derived from plants that are traditionally used in Morocco and have activity against SARS-CoV-2, could be explored in the search for a preventive or curative treatment against COVID-19. Furthermore, safe plants or plant extracts that are proven to stimulate immunity could be officially recommended by governments as nutritional supplements.

Authors: Zambrano Jimenez Noemí Andrea Barrera , Ratti Torres Andrea Isabel , Campoverde Chiquito Hilda Margarita , Cárdenas Choez Carlos Anthony
Published: November 2020

El síndrome de Cushing iatrogénico es la forma más común de hipercortisolismo. Los glucocorticoides se usan ampliamente para el tratamiento de diversas enfermedades, a menudo en dosis altas que pueden conducir al desarrollo de hipercortisolismo severo. El hipercortisolismo iatrogénico es único, ya que la aplicación de glucocorticoides exógenos conduce a la presencia simultánea de síntomas específicos del hipercortisolismo y la supresión del eje endógeno hipotalámico-pituitario-adrenal. La función principal de su terapia está relacionada con el problema de la abstinencia de glucocorticoides. Existe una considerable variabilidad interindividual en la supresión y recuperación del eje hipotalámico-pituitario-adrenal, por lo tanto, La retirada y sustitución de glucocorticoides solo se puede realizar de manera escalonada con un seguimiento clínico cuidadoso y exámenes de laboratorio regulares con respecto a la actividad endógena del eje hipotalámico-pituitario-adrenal. Tres complicaciones principales que pueden asociarse con la abstinencia de glucocorticoides son: reactivación de la enfermedad subyacente, insuficiencia suprarrenal secundaria y síndrome de abstinencia de esteroides.

Published: November 2020

Los Quistes Mesentéricos (QM) son una patología infrecuente, no obstante, importante en todo el mundo dada sus complicaciones. Un quiste es una cavidad o bolsa de tejido cerrada que puede estar llena de aire, líquido, pus u otro material y se pueden formar dentro de cualquier tejido del cuerpo. Los QM son aquellos ubicados en el mesenterio. La incidencia de estos quistes va desde 1 en 27.000 a 1 en 250.000. Desde el primer caso reportado en 1507, menos de 1.000 casos han sido publicados. Representan menos de 1 de cada 100.000 ingresos hospitalarios. Pueden llegar a presentar complicaciones graves como perforaciones, hemorragia y oclusiones, entre otras. El objetivo del presente estudio consiste en compilar el conocimiento existente acerca del dolor abdominal como síntoma frecuente del quiste mesentérico, así como la clasificación de estos quistes y otras manifestaciones clínicas importantes para orientar su adecuado diagnóstico. Para ello se prefirió un diseño investigativo bibliográfico, en el marco de una metodología de revisión. Se encontró que la presentación clínica de los QM es diversa, siendo tres síntomas básicos o de mayor frecuencia el dolor abdominal, acompañado de tumoración o masa y de síndrome de abdomen agudo. Entre las conclusiones se destacó la importancia de considerar todas las presentaciones características que acompañan con frecuencia a los QM, tales como: el dolor abdominal, la presencia o palpación de una masa y síndrome de abdomen agudo. Asimismo, reviste gran consideración aquellos pacientes asintomáticos o con otras presentaciones clínicas diferentes. En cualquier caso, los estudios de imágenes como el ultrasonido y la tomografía computarizada son fundamentales para establecer un diagnóstico preciso y oportuno.

Платиновые катализаторы, приготовленные методом пропитки по влагоемкости различных по природе носителей (TiO2, WO3/TiO2, CeO2, Al2O3, цеолит ZSM-5), испытаны в реакции окисления аммиака (ТПР—NН3+О2) и охарактеризованы с помощью комбинации физико-химических (РФА, ПЭМ, РФЭС) и кинетических (ТПВ—H2, ТПД—NH3) методов. На поверхности всех катализаторов платина присутствовала в высокодисперсной форме (средний размер частиц <1.5 нм), обеспечивая активность в окислении аммиака выше 150 °C. Основными продуктами окисления в диапазоне температур 150—250 °C были закись азота и молекулярный азот, тогда как оксиды NOx начинали формироваться при T > 250 °C. Наиболее высокая каталитическая активность наблюдалась в случае нанесения платины на TiO2, промотированный вольфрамом. Введение вольфрама модифицирует кислотность поверхности и влияет на окислительно-восстановительные свойства платиновых катализаторов. Установлено, что роль носителя заключается в стабилизации окисленных или восстановленных форм платины на поверхности, определяя общую активность в реакции окисления аммиака.

Published: November 2020

На основе численного моделирования проведено исследование локализованных рентгеновских стоячих волн, которые появляются внутри наноструктуры, составленной из кристаллической сверхрешетки и кристаллической пленки. Эти волны пространственно локализованы вблизи границы между сверхрешеткой и пленкой. Обсуждаются свойства таких волн и возможности их использования в эксперименте для исследования границы раздела сверхрешетка/пленка. Показано, что резонансное возбуждение локализованных стоячих волн происходит только при определенных значениях толщины слоя сверхрешетки, который граничит с пленкой, и величины постоянной кристаллической решетки этого слоя. По этой причине свойства указанных стоячих волн зависят от структуры границы сверхрешетка/пленка и приграничного слоя сверхрешетки.

Обсуждаются механизмы образования, кристаллическая структура, особенности дефектообразования и состав формируемой при пониженных (менее 900 °С) ростовых температурах на поверхности Si из углеводорода и гидридов сплошной карбидной пленки. Показано, что при выращивании в течение длительного времени толстых карбидных слоев под карбидным слоем образуется система макродефектов и подстилающая поверхность, подобная пористому кремнию. Присутствие переходного слоя твердого раствора между карбидным слоем и подложкой из кремния проявляется в положении линий люминесцентных спектров исследуемых структур в области ближнего ИК диапазона. Для установления наиболее вероятных механизмов наблюдаемых излучательных переходов проведен анализ температурного поведения спектральных линий и расчет характера распределения по слоям структуры возбуждаемых светом неравновесных носителей заряда.

Методом цепной радикальной безэмульгаторной полимеризации метилметакрилата в воде синтезированы партии высококачественных сферических частиц полиметилметакрилата с полидисперсностью менее 5 %. Средние диаметры в партиях составили от 237 нм до 447 нм. Модифицируя классическую технологию синтеза и заменяя от 4 об.% до 10 об.% дисперсионной среды на ацетон, удается варьировать физико-химические свойства получаемых субмикросфер, делая их более стабильными и прочными. На основе сфер полиметилметакрилата субмикронного размера получены двух- и трехмерные фотонно-кристаллические структуры — опалы. Кристаллическая структура опалов исследована методами инфракрасной спектроскопии и электронной сканирующей микроскопии. Спектроскопия показала, что частицы полиметилметакрилата содержат значительное количество воды, испарение которой приводит к усадке сфер. Кроме того, исследована стереорегулярность полимера, синтезированного в этой работе, а также определены температуры стеклования полученных образцов.
The Significant Impact of Intraformational Seal to Hydrocarbon Accumulation of Mixed Carbonate - Siliciclastic Sequences In Oligo-Miocene Interval, North Madura Platform, East Java Basin
Authors: Wijaya A. K.
Published: November 2020

The major reservoir within the North Madura Platform is the Oligo-Miocene Interval, which consists of oil and gas-bearing reservoirs, with multiple reservoir layers and multiple hydrocarbon contacts. The interval comprises of a stacked high frequency cycles of mixed carbonate-siliciclastic lithology component sitting in the paleo-high. It has become very important in the context of hydrocarbon accumulation since the components play very dissimilar roles and become reservoir-seal pairs, which resulted in the existence of intraformational seal. Based on the carbonate to siliciclastic ratio, from deeper to shallower interval, it can be divided into three cycles, namely first cycle with carbonate-dominated interval, second cycle with mixed carbonate-shale interval, and third cycle consists of massive carbonate sequences. The vertical hydrocarbon migration, both oil and gas, occurred within the known trap in the study area, filled the reservoirs from deeper to shallower interval with subject to seal capacity of each intraformational seal and leak points in the trap. The first cycle consisted of oil indicated that the seal breached as reservoir become fully saturated and some of oil and most of the gas leak. The second cycle, which consisted of multiple reservoir-seal pairs with oil and gas being accumulated depending on the seal strength. The third cycle, which is massive carbonate reservoir, is capped by thick marine shale as a roof seal that has been proven for gas being trapped. Better understanding on intrafomational seal, both micro and macro characteristics, can be highly beneficial to identify potential overlooked zone as well as contributing to the proper judgment on the likelihood of hydrocarbon accumulation.
Corrosion Modelling of Gas Wells With Excessive Sand Production: Case Study of Field Y in Indonesia
Authors: Biladi I.A.
Published: November 2020

This publication addresses risk analysis and the potential of sand induced tubing erosion in gas production wells due to high rate gas wells combined with excessive water and sand production. As gas wells become more mature, it is inevitable that water will be produced not only from vapour but also from aquifer. This presents a problem, especially in the unconsolidated wells where sands will be massively produced. Therefore, this publication addresses the potential of tubular damage from sand production in gas wells. The authors have analysed two published case studies using the approach of corrosion and erosion modelling, as well as tubing stress analysis to ensure long term tubing integrity. The calculations show that tubing design will be heavily affected by the sand prediction, especially for older tubing with thinner layer and possibility of deformation. Therefore, it is imperative to propose a more conservative tubing design especially in sour wells with excessive water production and where there is the possibility of sand production. It is also worth noting that as wells become older, with rising water saturation also comes the possibility of higher sand production due to the effects of shear stress. This publication should become an incentive for operators to conduct a more thorough completion examination for tubular integrity design in high rate gas wells especially ones with excessive sand production. This publication addresses a new approach in designing tubular goods for natural gas wells with the tendency of excessive sand production due to development of water saturation in mature gas wells.

Authors: Haris N. A.
Published: November 2020

Biogenic gas research in Nias and the surrounding area was performed using AI inversion and seismic attributes. The seismic data was acquired using Geomarine III for multi-channel seismic with a track length of 1740 km. Reservoir characterization was carried out to obtain the physical parameters of rocks affected by fluid and lithology. In the study area, there are hydrocarbon prospects in limestone lithology with a depth of around 1562 meters. Based on the results of sensitivity analysis, the cross plot between acoustic impedance and NPHI was sensitive in separating reservoir rock. The targeted reservoir in the limestone has physical characteristics of acoustic impedance values between 20,000 - 49,000 ((ft / s) * (g / cc)) and NPHI values in the range of 5% - 43%. The cross plot between the acoustic impedance and resistivity can separate the fluid-containing rocks with resistivity values in the range of 5 - 43 ohm-m. The results of acoustic impedance inversion using model-based methods show the potential for hydrocarbons in the "Singkel" well with acoustic impedance in the range 22938-277815 ((ft / s) * (g / cc)).

Çimlenme yüzdesi (%), çimlenme hızı (gün), kök ve sürgün uzunluğu (cm), fide yaş ve kuru ağırlığı (g/bitki) ile kuru madde oranı (%) incelenmiştir. Ayrıca hazırlanan solüsyonların elektriksel iletkenlik (EC) ve pH değerleri de belirlenmiştir. Araştırma sonuçlarına göre, sap solüsyonlarının EC değeri daha yüksek, pH değerleri ise daha düşük olduğu belirlenmiştir. Bitkilerin çimlenme yüzdesi ve hızında aspir çeşitlerine, bitki kısımlarına ve dozlara göre belirgin bir azalış veya artış elde edilmemiştir. Aspirde allelopatik ve ototoksik etkilerin sap kısmından kaynaklandığı, aspir köklerinin ise incelenen bitkiler üzerine etkisinin olmadığı tespit edilmiştir. Aspir çeşitlerinin allelopatik etkilerinin farklı olduğu ve Asol çeşidinin allelopatik ve ototoksik etkisinin daha az olduğu belirlenmiştir. Sonuç olarak, aspir saplarının buğday ve arpa bitkilerinin fide gelişimi üzerine allelopatik etkisinin olduğu, Asol ve Linas çeşitlerinin ise diğer çeşitlere göre daha az zararlı etkisinin olduğu söylenebilir.

Intertextualidad audiovisual en prácticas estético-políticas online. El caso del Colectivo Los Ingrávidos
Authors: Abril Valdez José Alberto
Published: November 2020

El objetivo de este artículo es analizar las prácticas creativas conectadas a la red —online— en las que la imagen digital adquiere un papel central en procesos en los que se propone repensar y cuestionar, desde lo estético, el lenguaje audiovisual y la industria mediática, así como la realidad político-social de México. Se toma como caso de estudio al Colectivo Los Ingrávidos —grupo de videastas mexicanos que adopta plataformas y redes sociales como su campo de acción—, y desde la perspectiva de la cultura digital, por medio del análisis intertextual, se reflexiona en torno a su producción. Se concluye que estas prácticas, como parte de procesos ciberactivistas, tienden a estetizar las preocupaciones sociopolíticas de un determinado momento, al vincular sus constantes a las del “artivismo” y recurrir a ejercicios propios de la posproducción —el remix audiovisual y la intertextualidad— como estrategias de interpelación.
Caballos de papel en las fiestas de Canarias
Authors: Fajardo Hernández Ricardo Marcos
Published: November 2020

En Canarias se mantienen vigentes varias danzas de caballitos de papel y queda constancia de otras muchas ya perdidas. La tradición oral sitúa su origen con el retorno de América de los emigrantes canarios; sin embargo, los referentes mediterráneos indican una procedencia europea y una vinculación a las celebraciones del Corpus Christi. La influencia francesa en Canarias podría determinar un posible origen provenzal. La polca es común en los caballitos de la isla de La Palma, en Tazacorte y Fuencaliente, mientras el sincretismo se apodera de los de El Tanque, Tenerife, con la interpretación del tajaraste, de probable adscripción aborigen. Las danzas refuerzan la identidad local pero han perdido parte de su carga simbólica ritual.

Published: November 2020

Dialium angolense is used in Bagira for its various medicinal properties particularly in the management of infectious diseases. In this study, the methanol and aqueous extracts of leaves and fruits were evaluated for their in vitro antioxidant and antimicrobial properties and their in vivo toxicity on Cavia porcellus. The major phytochemical classes of extracts were screened using standard in-tube reactions. The antimicrobial study was tested on Candida albicans, Escherichia coli, Salmonella typhi, Staphylococcus aureus and Streptococcus pneumoniae using agar well diffusion and dilution methods, while the antioxidant activity was evaluated by a DPPH assay. For the acute toxicity study, animals (6/group) were orally given in a single dose 5000, 1000 or 15000 mg of extract/kg body weight (BW) then observed for 14 days. In sub-acute toxicity assays, 150 or 300 mg/kg BW/day were orally given, and animals observed for 28 days. Total phenolics and total flavonoids contents ranged 1.19 to 1.61 mg GAE.g-1 and 0.45 to 1.01 mg QEg-1, respectively. The extracts presented antioxidant activity with IC50 ranging 4.9 to 6.9 µg/mL. The minimal inhibitory concentration (MIC) on tested strains ranged from 1.9 to 500 µg/mL with the aqueous extract of fruits as a most active extract: MIC=1.9 µg/mL on E. coli and C. albicans. No signs of toxicity were noted during the acute and sub-acute toxicity assessments, suggesting a maximal tolerate doses (MDT) and LD50 > 15000 mg/kg BW. This study highlights the antioxidant and antimicrobial activities of Dialium angolense and suggests that further studies be directed towards the isolation of active compounds.

Gene therapy is the transfer of genetic material to cure a disease or at least to improve the clinical status of a patient. One of the basic concepts of gene therapy is to transform viruses into genetic shuttles, which will deliver the gene of interest into the target cells. Safe methods have been devised to do this, using several viral and non-viral vectors. Two main approaches emerged: in vivo modification and ex vivo modification. Retrovirus, adenovirus, adenoassociated virus are suitable for gene therapeutic approaches which are based on permanent expression of the therapeutic gene. Non-viral vectors are far less efficient than viral vectors, but they have advantages due to their low immunogenicity and their large capacity for therapeutic DNA. The most commonly used DNA virus vectors are based on adenoviruses and adeno-associated viruses. An example of gene-knockout mediated gene therapy is the knockout of the human CCR5 gene in T-cells in order to control HIV infection. To improve the function of non-viral vectors, the addition of viral functions such as receptor mediated uptake and nuclear translocation of DNA may finally lead to the development of an artificial virus. Gene transfer protocols have been approved for human use in inherited diseases, cancers and acquired disorders. Although the available vector systems are able to deliver genes in vivo into cells, the ideal delivery vehicle has not been found. Thus, the present viral vectors should be used only with great caution in human beings and further progress in vector development is necessary.

Türkiye’de Hanehalkı Gelir Eşitsizliğine Etki Eden Faktörlerin Lorenz ve Yoğunlaşma Eğrileri ile Analiz Edilmesi ve Bölgeler Arası Karşılaştırma
Authors: TOPUZ Seher Gülşah , SEKMEN Taner

Adil gelir dağılımı, iktisat politikalarının çözmede yetersiz kaldığı en
temel iktisadi ve sosyal problemlerinden biridir. Dolayısıyla gelir
dağılımını düzeltecek daha iyi politikaların geliştirilebilmesi için gelir
eşitsizliğine yol açan nedenlerin belirlenebilmesi son derece önemlidir.
Bu çalışmanın temel amacı Türkiye’de gelir dağılımının güncel
durumunu ve bölgelerarası farklılıkları, Lorenz eğrisi ve yoğunlaşma
(konsantrasyon) eğrileri aracılığıyla incelemektir. Bu amaç hanehalkı
gelir bileşenlerinin analizi ile detaylandırılmaktadır. TÜİK tarafından
sağlanan 2018 yılına ait Hanehalkı Gelir ve Yaşam Koşulları Anketi
verileri ile yapılan analizlerde Türkiye için Gini katsayısı ve Palma oranı
sırasıyla 0,393 ve 1,798 olarak tahmin edilmektedir. Bunun yanı sıra
Türkiye’de gelir eşitsizliği coğrafi bölgeler arasında önemli oranda
farklılaşmaktadır. İstanbul ve Batı Marmara bölgeleri en yüksek gelir
eşitsizliğine sahip bölgelerdir. Bu sonuç, iktisadi gelişme ya da
büyümenin gelir eşitsizliğini azaltmada başarılı olamadığını
göstermektedir. Diğer yandan sosyal yardımlar, vergiler, menkul kıymet
ve gayrimenkul gelirlerinin gelir dağılımı üzerinde önemli etkilere sahip
olduğu sonucuna ulaşılmaktadır. Türkiye’de vergi sistemi gelir
eşitsizliğini azaltıcı yönde etkiye sahipken gelir gruplarının diğer gelir
bileşenlerinden aldıkları payın büyük kısmı genellikle üst gelir gruplarına
aktarıldığından dolayı bu gelir bileşenlerinin mevcut dağılımı gelir
eşitsizliğini artırıcı etkiler yaratmaktadır. Bunun yanı sıra, sosyal
yardımların da daha çok üst gruplara aktarıldığına ve düşük gelir
gruplarına yönlendirilemediğine dair kanıtlara ulaşılmaktadır. Son olarak
gayrimenkul gelirlerinin de adil dağılmadığı ancak menkul kıymet
gelirlerinden farklı olarak gayrimenkul gelirlerinin tüm gelir grupları
tarafından elde edilebildiği söylenebilir.
Reflections and Metaphoric Perceptions of Translator Trainees Related to Translators’ Status
Authors: DİŞLEN DAĞGÖL Gökçe , İŞPINAR AKÇAYOĞLU Duygu
Published: November 2020

Throughout history, translation has had a notable role in the spread of knowledge. Contrary to what is assumed, translation is not confined to just finding the equivalences of words. Translators are quite active in the translating process, and translation, as a multidimensional act, requires various skills and responsibilities. However, despite the fact that translation is a very old human activity, translation as a profession seems to require more time to gain the desired status, which is the focus of this study. This study aims to reveal prospective translators’ perceptions about their future profession before they start working as professional translators, and it focuses on students’ viewpoints about translation, translators, status of translators and the probable ways to enhance the status of translators. Hence, 23 second-year students enrolled in the Department of Translation and Interpreting Studies were included in this study. Data were collected qualitatively through reflection papers and open-ended question forms that aimed to elicit the participants’ views regarding the definition of translation and suggestions about improving the status of translators. The findings indicate that translator trainees have different descriptions regarding translation, translators, and translation processes and think that translators have low-status. The study provides a number of suggestions of prospective translators to increase the status of the profession.
Walking the Line between Order and Chaos: A Teacher-Researcher’s Reflection on Teaching Mathematics with Challenging Tasks in Primary Classrooms
Authors: Russo James Anthony
Published: November 2020

Encouraging teachers to incorporate challenging tasks into mathematics instruction is frequently implored by mathematics educators, due to its potential impact on student learning and persistence. However, there is evidence that teaching with such tasks is pedagogically demanding, particularly for less expert teachers. To support a developing dialogue around the experience of teaching with challenging tasks, I document my experience of teaching 84 lessons involving challenging tasks to three grades of year 1 and 2 students as part of a research project. Adopting a ‘practitioner inquiry’ lens, I analyse my reflective journal to reveal five themes: classroom management, maintaining and managing cognitive demand, time management, tensions between discussion objectives and tensions in task design. Implications for teacher professional learning are discussed.
What Can Instructors Focus on when Improving Undergraduate Science Experiments? Supporting a Cross-Disciplinary Approach
Authors: Yeung Alexandra , Cornish Scott , Kable Scott , Sharma Manjula Devi
Published: November 2020

For nearly two decades, the Australian national project Advancing Science and Engineering through Laboratory Learning (ASELL), has been using an evidence based approach to improve undergraduate experiments. This paper presents the ASELL Students Laboratory Experience (ASLE) survey, administered to 2691 students in five disciplines: biochemistry, biology, chemistry, physics, and pharmacology. The 14 item survey probes students’ perceptions of an experiment, practical or fieldwork. An exploratory factor analysis extracted two factors, ‘experiment-based motivators’ and ‘course-level resources’, and both factors correlate well with ‘overall’ learning experiences. Each survey item was also compared to the ‘overall’ learning experiences of the experiment, revealing the most critical elements of each experiment. The implications of this analysis, for practitioners is that the survey items in the ‘course-level resources’ taper off indicating that after an optimum value, further investment in these aspects do not necessarily influence student perceptions of their learning experiences. On the other hand, the survey items in the ‘experiment-based motivators’ behave differently in that they do not taper off indicating that further investment can influence experiences. How these factors relate to the overall experience suggest they correspond to the well-known two-factor theory of motivation.
A Decade of Agriculture Graduates’ Employability and Career Pathways
Authors: Wilkes Janelle , Burns Adrienne
Published: November 2020

There is increasing pressure on universities to produce employable graduates. Currently, the University of New England (UNE) has a suite of undergraduate agriculture courses. The project used an evidence based approach which evaluated graduate’s employability based on their choice of course and the relevance of Australian Threshold Learning Outcomes (TLOs) for Agriculture, which underpin UNE’s agriculture courses. The past decade of UNE agriculture graduates (2005-2016) were invited to participate in an online survey. Of the respondents, 95-100% agreed each TLO was relevant to their current employment. The initial industries that graduates were employed in after graduation were agronomy, agribusiness and animal sciences. Of all graduates who are currently employed in industry, three quarters had changed employers, with two thirds moving to another agricultural industry since commencing work. Over half of the respondents had engaged in additional study from short courses to PhDs, with about 20% studying to become vocational, primary or secondary teachers. For many graduates on-campus residential college life was important for developing positive connections in learning, social activities and employment networks which persisted post-graduation. Survey results were used to inform the development of an online career pathway resource for prospective and current students, and information from the TLO survey has been fed back into unit and course reviews.

Published: November 2020

The Masterclass in Horticultural Business is a national program requested by and tailor-made for Australian business managers and entrepreneurs in horticulture. The University of Tasmania has developed the Masterclass in collaboration with the internationally recognised higher education providers Wageningen University and Research (Netherlands) and Lincoln University (New Zealand). The Masterclass builds on our strong links between teaching and research, development and extension in horticulture. The Masterclass, delivered as a new pre-tertiary qualification (Diploma in Horticultural Business) through the University of Tasmania, combines a strong understanding of horticulture production and business practices. The integrative program has a basis in production horticulture with modules including; people and culture, supply chain management, logistics, law, export, business planning and entrepreneurship. First offered in 2017, the program has attracted a range of industry professionals in horticulture. The design of the Masterclass for a national cohort of students necessitated online delivery that is highly-professional, flexible and relevant to people working in the horticultural industry to foster innovative and creative thinking and engagement among students. Module topics and assignments are designed to promote interaction of the participants with their staff (if they are business owners) or employers (if they work for a business owner). In this way the students are applying learnings to their workplace, raising questions and stimulating discussions about agribusiness. The high degree of industry engagement and endorsement as well as international collaboration in the design of the Masterclass is unique. The intention is that this Masterclass develops strong industry linkages and adds to the partners internationally recognised reputation in agricultural and business education. One of the major deliverables from the course is a student produced business plan, which must be delivered to industry and academic examiners. Many students have provided feedback indicating that they intend to put this business plan into action by applying it to new opportunities for their businesses.
