Quality Improvement Incentive Strategy in Agricultural Products Supply Chain Under Social Preference
Authors: Qin Yanhong , Guo Kai Jing
Published: August 2021

This paper sets Stackelberg model of bilateral quality efforts decision dominated by supermarket in the agricultural products supply chain by considering fairness concern and altruistic reciprocity. We use backward induction method to compute and prove that A3P’ fairness concern can play the role of profit distribution mechanism in agricultural products supply chain, and has no effect on the bilateral quality efforts decision, total profit of supply chain and objective efficiency, but can improve both the subjective and objective fairness degree. Meanwhile, supermarket’s altruistic reciprocity can improve the total quality efforts and total profit of supply chain, optimize the objective efficiency and subjective fairness of supply chain.
Ricerca clinica e ricerca empirica
Authors: Fava Emilio
Published: August 2021

In questo articolo l’autore tende a mostrare come possa funzionare l’integrazione tra ricerca clinica e ricerca empirica secondo il modello della perturbazione reciproca tra i dati e le osservazioni prodotte da due distinti sistemi di conoscenza. Viene messa in evidenza come esista un forte influenzamento della ricerca clinica sulle ipotesi che vengono testate negli studi empirici e il potenziale effetto dei dati empirici sulla chiarificazione e messa a fuoco di questioni fondamentali per la pratica clinica e la riuscita dei trattamenti. Da qui il potenziamento di ‘buone pratiche’ rispetto ad errori e importanti disconoscimenti dei fattori che determinano l’esito delle terapie. Conseguentemente l’interesse si orienta sui percorsi formativi nella prospettiva di favorire un approccio in cui l’attenzione del clinico in formazione si equilibra tra ‘punti di ancoraggio’ osservabili, mutuati dalla ricerca, approfondimenti intuitivi e quei pattern descrittivi derivati dalla esperienza clinica che arricchiscono la letteratura psicoanalitica.

Published: August 2021

Background :

Transcatheter pulmonary valve implantation (TPVI) is a surgical alternative for correcting dysfunctional right ventricular outflow tract conduits in previously operated patients. MyVal transcatheter heart valve (THV) (Meril Life Sciences, India), a new transcatheter valve designed for aortic position has not been used for TPVI.

Methods :

Patients with stenosed dysfunctional conduits from the right ventricle to pulmonary artery (RV-PA) were prestented after initial computed tomography and balloon interrogation before the implantation of MyVal. Size of MyVal was chosen based on the final diameter of the prestent. Procedural details and post-TPVI follow-up were analyzed.

Results :

Seven patients aged 17–60 years (median 26 years) had stenosed RV-PA conduits implanted 5–17 years (median 9 years) ago for tetralogy of Fallot in three, following Ross procedure in two, repair of pulmonary stenosis, and following PA debanding in one patient each. Prestenting improved the conduit diameter from 9.3 ± 2.8 mm to 20.8 ± 1.1 mm and relieved the gradient from 87.3 ± 31.7 mmHg (50–137 mmHg) to 12.7 ± 6.4 mmHg (5–20 mmHg). A 23 mm MyVal was implanted in all the seven patients successfully; one patient needed an additional 24.5 mm MyVal valve in valve implantation for residual regurgitation. The mean fluoroscopic time and dose area product were 38.7 ± 25.3 min and 66.917 ± 39.211Gray. cm2, respectively. At a median follow-up duration of 16 months (10–22 months), all patients were asymptomatic receiving dual antiplatelet therapy with no PR and the gradient was 12.5 ± 5.8 mmHg on echocardiography. Although one patient needed an additional valve-in-valve implantation, there were no valve-related adverse events.

Conclusions :

Early experience of TPVI with MyVal THV in prestented conduits is encouraging with procedural success in all patients and acceptable mid-term outcomes.
Ultrasound-guided transjugular embolization of ruptured huge venous ectasia of a Cognard IV tentorial dural arteriovenous fistula as a first-stage lifesaving procedure
Authors: Panagiotopoulos Vasileios Evangelos , Messinis Lambros , Constantoyannis Constantine , Zampakis Petros
Published: August 2021

Tentorium is a rare location of the brain dural arteriovenous fistulae (DAVF) consisting <4% of cases. Hemorrhagic clinical presentation is common, as cortical venous reflux consists a usual characteristic of tentorial DAVF’s angioarchitecture. We present a case of transvenous, transjugular embolization of a ruptured huge venous ectasia of a Cognard IV tentorial middle-line DAVF, as a first step life-saving procedure. Initially, a transarterial antegrade embolization attempt was performed but failed due to the tortuous course of arterial feeders. Subsequently, the internal jugular vein (IJV) was directly catheterized under ultrasound (U/S) guidance and a 6F guiding catheter was placed at the ipsilateral transverse sinus. A microcatheter was navigated inside the venous ectasia and eventually, coils were deployed inside causing complete occlusion of the huge venous ectatic aneurysm. In this way, initial occlusion of the venous ectatic ruptured point has been achieved as a first-stage lifesaving treatment. Subsequently, the patient underwent stereotactic radiosurgery for the DAVF 4 months after embolization. Angiographic control with digital subtraction angiography 2 years after embolization and additional stereotactic radiosurgery revealed complete occlusion of the tentorial DAVF. The patient experienced complete neurological recovery. Direct puncture of the IJV under U/S guidance may assist transvenous embolization of ruptured venous ectasia in case of complex tentorial middle-line DAVFs type IV when the ecstatic venous aneurysm is recognized as the bleeding source.
The entity of the trapped fourth ventricle
Authors: Panagopoulos Dimitrios , Karydakis Ploutarchos , Themistocleous Marios
Published: August 2021

An isolated or trapped fourth ventricle is a relatively rare, although serious, adverse effect of hemorrhagic, infectious, or inflammatory processes that involve the central nervous system. This entity usually occurs after successful shunting of the lateral ventricles and may become clinically evident with the development of delayed clinical deterioration. This decline of the neurological status of the patient is evident after an initial period of improvement of the relevant symptoms. Surgical treatment options include cerebrospinal fluid shunting procedures, along with open surgical and endoscopic approaches. Complications related to its management are common and are related with obstruction of the fourth ventricular catheter, along with cranial nerve or brainstem dysfunction. We used the keywords: “isolated fourth ventricle,” and “trapped fourth ventricle,” in PubMed® and Web of Science®. Treatment of the trapped fourth ventricle remains a surgical challenge, although the neurosurgical treatment armamentarium has broadened. However, prompt recognition of the clinical and neurological findings that accompany any individual patient, in conjunction with the relevant imaging findings, is mandatory to organize our treatment plan on an individual basis. The current experience suggests that any individual intervention plan should be mainly based on the underlying pathological substrate of hydrocephalus. This could help us to preserve the patient’s life, on an emergent basis, as well as to ensure an uneventful neurological outcome, maintaining at least the preexisting level of neurological function.
Can Philanthropy Enable Collective Action to Conserve Rivers? Insights from a Decade of Collaboration in the Colorado River Basin
Authors: Gilson Gina G. , Garrick Dustin E.
Published: August 2021

Philanthropy plays an important but often invisible role in conserving rivers. We examine the influence of philanthropy on collective action and collaborative governance within the Colorado River Basin, a region where philanthropic support has been growing to achieve conservation objectives. Our short communication combines financial data, interviews, and documentary evidence to capture the opportunities and risks associated with philanthropy's increasing role. Financial expenditures are substantial, averaging $30.8 million USD per year from six large foundations (2013-2019). This funding has enabled collective action, particularly at the basin level, by strengthening or creating new forums for collaboration and investing in technical expertise to equip a broader range of voices in decision-making. It has also favoured market-based strategies and discourses, created dependencies for smaller organisations, and, in some instances, reinforced structural barriers to participation. We recommend transparent reporting of philanthropic spending related to collective action and conservation governance, and argue that foundations should explicitly consider and address legacies of exclusion for marginalised actors and groups.

Authors: Oluwole E.O. , Adeyemo T.A.
Published: August 2021

Background: Over 300,000 babies are born worldwide with sickle cell disease, mostly in low- and middle-income countries with the majority of these births in Africa. Nigeria has the largest population of people with sickle cell disease with about 150,000 children born with the disease every year. This study assessed the knowledge, attitude and willingness to screen younger infants for sickle cell disease among mothers attending immunization clinic in an urban community in Lagos, Nigeria.Methods: A cross-sectional descriptive study was carried out at primary health care centres in Somolu Local Government Area in Lagos, Nigeria. Two hundred and ninety-one mother-infant pairs were consecutively recruited from August 2019 to January 2020. Data were collected with a pre-tested, interviewer-administered questionnaire. The analysis was done using SPSS version 22 software. Univariate and bivariate analysis were conducted with the level of significance set at p<0.05.Results: The mean age of respondents was 29.9 ± 5.4 years. Most 212 (72.9%) were aware of sickle cell disease. One hundred and fifty-one (71.2%) of those who were aware of sickle cell disease had good knowledge while 148 (69.8%) had a positive attitude towards SCD prevention. Majority of the respondents 180 (84.9%) were willing to screen their infants for sickle cell disease. A statistically significant association was found between good knowledge and positive attitude towards SCD (p<0.001).Conclusion: There is the need for increased education of mothers of younger infants attending routine immunization clinic about SCD for better knowledge, attitude and willingness for early infants screening of SCD.

Published: August 2021

Background: Although large families are desired in Nigeria, women tend to want fewer children than men but are often unable to limit or space childbirth due to gender dynamics within relationships. Studies have identified men as a significant barrier to the use of  contraceptives by their wives. The study explored married men’s knowledge and perception on family planning (FP), involvement in FP, barriers and facilitators of male involvement (MI) in FP in Sokoto Metropolis.Methods: A qualitative study was done among married men in Sokoto Metropolis in November 2017. Four focus group discussions were conducted among thirty-two men grouped based on educational status and age. Data was transcribed verbatim and a content analysis on emerging themes was done.Results: All the participants were aware of FP and most of them said that it is beneficial to everyone in the community. Most of the  participants perceived that FP is an issue for both men and women. All the participants said that men should be involved in FP. The barriers to MI in FP mentioned were lack of knowledge on FP and poverty while increasing awareness on FP, religious leaders and traditional rulers championing FP, and making FP free were the facilitators suggested.Conclusion: The participants said that FP is beneficial to everyone in the community and men should be involved in FP. Traditional and religious leaders should be made the champions of FP in their various communities to improve acceptance and utilisation.

Authors: Rahman A. , Bayram I. , Gultepe E.E.
Published: August 2021

Effects of Mentha piperita (peppermint) extract and juice on performance and immune parameters were evaluated in laying hens. A total of 252 Babcock laying hens were allocated to seven treatments with four replications of nine hens. The control hens were fed a basal diet without supplementation. Other hens were given diets supplemented with mentha extract (ME) at 50 (50ME), 100 (100ME), and 200 (200ME) mg/kg of feed or with 50 mentha juice (50MJ), 100 (100MJ) and 200 (200MJ) mg/L that was provided in the drinking water. No significant differences were detected among treatments in bodyweight, feed intake, egg mass, egg production, eggshell breaking strength, Haugh unit, and haematological and serological parameters. The ratio of gram feed to gram egg mass (feed conversion) was significantly better in the birds that received 100ME and 200ME compared with the control hens. The yolk colour index was higher in mid trial analysis (28th day). Thus, although the ME supplementation had a positive effect on feed conversion ratio and egg yolk colour at dosage rates up to 200 mg/kg, further research is needed to establish the efficacy of this herbal product and to determine the most appropriate amount to include in diets for laying hens.

Published: August 2021

Forages play an important role in ruminant animal production worldwide. Unlocking the nutritional potential of poor-quality tropical forages with fibrolytic enzymes would improve forage digestibility and utilization. Using in vitro and in vivo methods this study investigated the effect of pre-treating Smutsfinger hay for 24 hours with a mixture of fibrolytic enzyme (100% cellulase; 75% cellulase: 25% xylanase; 50% cellulase: 50% xylanase; 25% cellulase: 75% xylanase; 100% xylanase and a control with no enzyme) on ruminal fermentation and digestibility of nutrients by sheep. For in vitro fermentation, dry matter, neutral detergent fibre (NDF) degradability and volatile fatty acids (VFA) were determined with standard procedures. The same treatments were used for an in vivo digestibility trial using Merino sheep in a 6 x 6 Latin square design. Feed intake and total tract digestibility were recorded. Rumen fluid samples were collected daily, preserved, and analysed for VFA. The addition of 100% cellulase enzyme to Smutsfinger hay in vitro increased (P <0.05) NDF degradability and gas production compared with the control and inclusion of 100% xylanase enzyme. Both 100% cellulase and xylanase enzymes significantly reduced in vitro end time fermentation pH. A 50:50 mixture of cellulase and xylanase plus enzyme in vivo, increased acetate, total VFA concentration, and higher NDF and ADF digestibility of the test feed compared with the control. Inclusion of a 50-75% mixture of cellulase and 50-25% xylanase enzymes treatment led to higher gas production and butyrate concentration, decreased ruminal pH and improved nutrient digestibility.
Short communication: Pelleting increases the metabolizable energy of de-hulled sunflower seed meal for broilers
Authors: Karkelanov N. , Chobanova S. , Whiting I.M. , Dimitrova K. , Rose S.P. , Pirgozliev V.
Published: August 2021

The study examined the effects of two methods of processing de-hulled sunflower seed meal (SFM) from the same batch of sunflower seeds. Sunflower seed meal was fed to broilers as meal (MSFM) or after it had been pelleted (PSFM) at 75 °C and 360 kPa pressure to pass through a 3 mm mesh. Three diets were prepared, namely a balancer feed (BF) and two diets containing 200 g/kg MSFM or 200 g/kg PSFM. They were fed to 30 pens (two birds each) with male Ross 308 broilers, from 8 to 21 days old, following randomization. Data were analysed by ANOVA. Two pre-planned orthogonal contrast tests were performed to compare overall differences between the diets containing SFM and BF and between diets containing the MSFM and PSFM. The BF had a very different nutrient composition from the complete feeds containing SFM so, as expected, there were differences in growth performance and nutrient retention. The diet containing PSFM had greater apparent metabolizable energy corrected for N retention (AMEn) and dry matter retention (DMR) than that containing MSFM. The use of the substitution method showed the PSFM had AMEn that was 18% greater than the MSFM (8.79 vs 7.47 MJ/kg DM). Under the conditions of the current study, incorporating PSFM in a mash broiler feed increased dietary AMEn compared with the same feed containing MSFM. Further studies are needed to identify whether the benefits of pre-pelleting SFM remain after this product has been incorporated in complete pelleted broiler feeds.

Authors: Fernàndez Ernesto Carmona , Izquierdo Jorje Luis Pineda , Suàrez Osiris
Published: August 2021

Pleomorphic adenomas account for the majority of parotid masses, typically arising in the tail of the gland and enlarging slowly. Most are 2 to 6 cm in size when resected. We report the resection of a benign mixed tumour of the left parotid gland with a history of bleeding. The resected tumour measured 21 cm in diameter, weighed 1.81 kg, and on pathologic examination was a benign mixed tumour without malignant degeneration. The implications of this unusual case for the management of mixed tumours are discussed with a review of the literature.
Fibropapillomatosis infection in a population of green turtles at Watamu Bay, Kenya
Authors: Jones Sharon M. , Caspi Itamar , Lucas Charles
Published: August 2021

Anthropogenic stressors from onshore and offshore activities can act as driving factors of disease for a wide range of marine organisms. Green turtles (Chelonia mydas) are prominently afflicted with a tumour-causing disease known as fibropapillomatosis (FP) caused by the chelonid alphaherpesvirus ChHV5. Previous studies indicate that pathways of FP transmission may be genetic (vertical transmission) or linked to causal factors in a turtle’s environment (horizontal transmission). In this paper patterns of FP prevalence were examined in 10,896 records of green turtles caught or found stranded around Watamu Bay, Kenya, between 2003 – 2020. Findings were focused on locational and seasonal factors that may potentially influence infection. The findings show that FP prevalence varies significantly on an annual basis. Location significantly influenced infection prevalence, with prevalence higher in open ocean sites than sites located within the creek. Infection prevalence was highest at sites around the creek mouth and north of the creek mouth, with both regions exhibiting disparate annual patterns of infection. This paper is the first to examine long-term trends of FP prevalence in-depth in this region and has implications for the health of turtles and marine biota found along the Kenyan coast, and potentially within the wider Western Indian Ocean region. The findings emphasize the need to distinguish the infection pathways of causative agents via: i) further examination of the links between infection and environmental and/or biont community factors; and ii) the collection of data pertinent to the genetic diversity of green turtles and associated ChHV5 viral strains occurring in the Western Indian Ocean.

Authors: Li Gengze , Li Shuaixuan , Yan Jun
Published: August 2021

Power station is an important basic power generation organization, and its operation status is related to the continuous power generation capacity. At present, a large number of physical network equipment and intelligent equipment are used in pumped storage power station, which makes its data mass growth and its operation state become a difficult problem. Accurate operation monitoring results can provide decision support that power generation planners and government, but also reasonably dispatch corresponding resources. In the past, decision tree algorithm was used in operation condition monitoring, which has the problem of data distortion and affects the accuracy of monitoring results. Based on the above reasons, this paper combines the wavelet function and decision tree algorithm, proposes an improved decision tree algorithm to eliminate redundant data in order, and uses wavelet function to cluster distorted data, so as to improve the accuracy and computational efficiency of the algorithm. Matlab simulation results show that: decision tree algorithm can eliminate 90% of redundant data, reduce the impact of feature data extraction on decision tree. At the same time, the improved accuracy is 98%, the calculation time is less than 25s is better than that, the decision tree algorithm. Therefore, the improved algorithm can optimize the condition monitoring of pumped storage power station.

Published: August 2021

Este artigo pretende indicar algumas notas Eclesiológicas a partir do Pontificado do Papa Francisco, especialmente no que se refere ao sentido da identidade/missão da Igreja esboçado por ele. Para tanto, procura-se dialogar este sentido com a complexa realidade atual, na qual vive a humanidade frente aos dramas causados pela Pandemia do Coronavírus. Disso resulta quatro pontos a serem desenvolvidos: primeiro, os princípios fundamentais a fim de ver a realidade hodierna; segundo, olhar propriamente a realidade; terceiro, notas constitutivas do sentido da identidade/missão da Igreja a partir do Pontificado do Papa Francisco; quarto, colaborações da Igreja para com a humanidade diante da Pandemia do Coronavírus. Assim, pode-se constatar uma maior compreensão da identidade/missão como um estado permanente de saída eclesial, de modo que se revelam como dois lados da mesma moeda.
Teologia da Libertação: 50 anos de uma experiência pé no chão!
Authors: Sbardelotti Emerson
Published: August 2021

A Teologia da Libertação é antes de tudo, uma libertação da Teologia. Ela quer ser uma Teologia para a nossa situação e não simples xerox da Teologia de outros países. Sua marca registrada nestes 50 anos de experiência pé no chão é a Opção pelos Pobres, contra a pobreza – nada de exaltar a pobreza -, a favor da vida e da liberdade. O que move a Teologia da Libertação é o seguimento à Jesus de Nazaré, sua pedagogia, sua prática e sua espiritualidade libertadora. Num país de miseráveis, de intolerância, violento e racista que se tornou o Brasil, a Teologia da Libertação continua sendo útil e necessária. O objetivo é agradecer a todos os teólogos e teólogas da libertação, que vieram antes de nós, aqueles e aquelas que estão no nosso meio, e que alimentam nossa esperança, questionando e se deixando questionar, que abriram e que abrem novos caminhos.

Published: August 2021

Desde que foi declarada, no final de 2019, espalhando-se rapidamente por todo o mundo, a pandemia da Covid-19 foi objeto de várias interpretações, marcadas, inicialmente, pelas experiências da quarentena, das intervenções políticas dos estados, impondo o distanciamento social, medidas protetivas, como o uso de máscaras, novos cuidados com a higiene, sem contar as novas formas de trabalho, o home office, e as terríveis imagens dos hospitais superlotados e o número impressionante de mortos. As igrejas tiveram que ser fechadas e muitas de suas atividades foram oferecidas no formato virtual, provocando uma série de questões de caráter pastoral e teológico. No Brasil uma série de textos foi elaborada logo que se declarou a quarentena, provenientes de vários âmbitos do saber. O presente estudo propõe uma breve retomada de alguns desses textos, escritos nos primeiros meses do isolamento social, a maior parte de caráter ensaístico, perguntando-se sobre sua pertinência um ano e meio depois do início da pandemia.

Published: August 2021

The postal network is a comprehensive set of several subsets, namely, postal infrastructure (consisted of objects and means), transportation networks, and human resources. It is organized by specific considerations of every country, following practices outlined by national and international regulation. Geographic Information System is a tool specialized for spatial data and network analysis. It can help identify shortcomings in a network environment, conditioned by a specific set of criteria and provisions. Spatial data and characteristics of the postal network are taken into consideration. The research area’s transportation infrastructure and administrative data are also needed for quality analysis of the postal network. The application of GIS in this paper is made following one County’s example in the Republic of Croatia.
Mentoring: A Role to Facilitate Academic Change

Published: August 2021

The concept of mentoring is presented, including a historical overview and definitions of both mentor and protégé as well as corresponding typical roles and responsibilities. Theoretical models of mentoring are presented and contemporary views on using mentors to create meaningful curricular change are discussed. In particular, the overall results of the American Occupational Therapy Foundation’s Curriculum-Mentoring Project are presented. The conclusion appears to be that both the process and outcomes of curriculum change seem to be highly dependent on the communication style and make-up of the faculty and their relationship with the mentor.

Umsetzung einer wirksamen Compliance in globalen Lieferketten am Beispiel der Anforderungen aus der europäischen Chemikalien-Regulierung an die Automobilindustrie
Authors: Winkler-Portmann Simon
Published: August 2021

This publication based on a master thesis explores the challenges of the automotive industry regarding the European chemical regulations REACH and CLP, as well as potential improvements of the current compliance activities and the related incentives and barriers. It answers the research question: "To what extent should the compliance activities of actors in the automotive supply chain be extended in order to meet the requirements of European chemicals regulation; and where would it help to strengthen incentives in enforcement and the legal framework?“. The study’s structure is based on the transdisciplinary delta analysis of the Society for Institutional Analysis at the Darmstadt University of Applied Sciences. It compares the target state of the legal requirements and the requirements for corresponding compliance with the actual state of the actual compliance measures of the automotive players and attempts to identify their weak points (the delta). The main sources for the analysis are the legal texts and relevant court decisions as well as guideline-based expert interviews with automotive players based on Gläser & Laudel. As objects of the analysis, there are in addition answers to random enquiries according to Article 33 (2) REACH as well as the recommendations and guidelines of the industry associations. The analysis identifies the transmission of material information in the supply chain as a key problem. The global database system used for this purpose, the IMDS, shows gaps in the framework conditions. This results in compliance risk due to the dynamically developing regulation. In addition, the study identifies an incompliance of the investigated automobile manufacturers with regard to Art. 33 REACH. In answering the research question, the study recommends solutions to the automotive players that extend the current compliance activities. In addition, it offers tables and process flow diagrams, which structure the duties and required compliance measures and may serve as basic audit criteria. The analysis is carried out from an external perspective and looks at the entire industry. It therefore cannot cover all the individual peculiarities of each automotive player. As a result, the identified gaps serve only as indications for possible further compliance risks.
Energia solar fotovoltaica

Published: August 2021

O artigo se propõe a analisar o setor solar fotovoltaico no Brasil, cobrindo como o planejamento do setor elétrico fez sua inserção no período 2011-2020 e o que prevê para década 2021-2030 ou seja, uma análise crítica dos resultados da década que se encerrou e das propostas/tendências para a década que se inicia. Mostra-se como o Brasil, ainda que tardiamente, se alinhou completamente à tendência global, ainda que aqui a questão ambiental não seja um motor relevante para a alta penetração já alcançada atualmente e que se delineia nos cenários para o futuro. Destaca-se os três segmentos de mercado: a solar centralizada, a geração distribuída e as oportunidades nos sistemas isolados. Conclui-se ressaltando alguns desafios e barreiras ainda existentes, alguns eventuais retrocessos no incentivo a essa fonte, exatamente por se priorizar a competitividade entre as fontes, relevando seus atributos ambientais. Todavia, a tendência de preços declinantes faz compensar os retrocessos sinalizando perspectivas de crescentes percentuais de participação na matriz elétrica nacional.

El diseño gráfico en crisis: Entre la precarización y los bullshit jobs
Authors: Grupo de Investigación en Problemáticas del Diseño Gráfico
Published: August 2021

A partir de dos ejemplos recientes, nuestro trabajo indaga sobre dos tendencias actuales en el diseño gráfico. Postulamos que, en tanto labor, al interior del imaginario social actual, el diseño está tensionado por dos polos. Una tendencia lo considera un bullshit job, la otra lo ubica en la esfera del precariado. Nos proponemos, a partir de los ejemplos del Festival Lollapalooza (Argentina) y el de Correos de España, ver cómo funcionan los discursos y prácticas que conducen a uno u otro polo.
Party Systems and Redistribution in Democratic Latin America
Authors: Mauro Vincent
Published: August 2021

A redistributive wave across Latin America provided credence to existing explanations that emphasize the importance of democracy and the political left for democratic redistribution. Yet, neither of these theories tells the entire story behind the contemporary politics of inequality
in Latin America. This article stresses the importance of party systems for democratic redistribution, especially their role in increasing the scope of social policy as well as igniting competitive electoral environments that incentivize political elites to redistribute, leading to the amelioration
of inequality over time. Utilizing a time- series cross-sectional dataset on fifteen Latin American countries covering the period of 1990?2015, and extending the analysis to sixty-five global democracies, this article finds that countries with institutionalized party systems exhibit greater
income redistribution and lower levels of inequality than those with inchoate counterparts.

Student evaluations of teaching as a tool for making summative personnel decisions at a tertiary institution
Authors:   , Harrison Janet Elizabeth
Published: August 2021

A random sample of learners and educators, at a Technikon, was surveyed with regard to the teaching behaviours that most contributed to effective learning. Variables included in the survey were identified by a focus group of educators and learners who negotiated the content of the survey questionnaire over a six-week period. This methodology ensured that learners were able to voice their interests in what should be assessed in a summative learner evaluation of teaching. Educator opinion on what feedback they would be prepared to receive from learners was a necessary touchstone to ensure compliance with legislative and administrative requirements for good practice in performance appraisal. Educators and learners agreed on thirteen of fourteen significant educator behaviours which learners felt contributed to effective learning. These findings suggest that a) learners and educators may not be as dissimilar in their teaching and learning agendas as previously thought and b) that participant meanings regarding teaching and learning practice may playa large role in defining teaching competence.

An investigation into the problems experienced by female heads of department as a result of prejudice against women in promotion posts : with reference to primary schools in the Isipingo area
Authors:   , Singh Neermala
Published: August 2021

This research focused on an investigation into the problems female heads of department experienced with reference to the primary schools in the Isipingo area. For a successful and a balanced education on a global basis, women must be seen to be equally capable of becoming leaders of educational institutions. The purpose of this research was to ascertain how educators react to the leadership of female heads of department in primary schools. More specifically, the objective of this research was to investigate the problems that heads of department experience, mainly because they were women. A literature survey of the functions of the head of department enabled the researcher to focus on the areas that the head of department had to give her attention to in order to develop an effective team. Focus was on organizational, administrative and professional matters determining the level of similarities between the English, American and South African education systems. Research was conducted by means of a questionnaire applied to a representative sample of educators from all levels of the hierarchy of educators. The qualitative method provided a systematic investigation of the topic. The research sought to understand behaviour from the 'action' point of view where the objective was to discover the specific experiences of the respondents.
The role of governors and teachers' unions in the promotion of senior management in public schools in the City of Durban district, 1997-2000
Authors:   , Rangraje Ismail
Published: August 2021

This research investigates the role of school governors and teachers' unions in the management of the promotion process for principal and deputy principal posts in selected public primary and secondary schools in the City of Durban District during the period 1997 to 2000. The. study is concerned with exposing the problems in the present selection procedure by evaluating it and seeking ways to improve its implementation and thereby strengthening the role of school governors and teachers' unions in the process. It is the function of the governing body of a public school to appoint a promotions committee which selects personnel for promotion posts at schools. The selection process is fraught with many difficulties such as the lack of proper training for selectors, illiterate selectors, nepotism, bias and intimidation by selectors. This research investigates the inadequacies, which exist in the selection process. The issues investigated include the process of selection of staff for promotion posts, the competence of the selectors, the criteria used for selecting and the problems experienced by the selectors. The investigation is executed using the qualitative research method. The instruments used in this investigation are observation, a review of related literature and structured interviews with different members of the promotions committee. In South Africa there is very little theoretical research available on the topic. The researcher has had to draw on literature concerning the promotion of teachers in Local Education Authority (LEA) schools in England and Wales. Recommendations for improvement include adequate training of selectors, greater involvement by officials from the KwaZulu-Natal Department of Education and Culture to keep nepotism in check, more realistic time frames for shortlisting and interviewing, gradual progression of candidates from Level One to Level Four, verification of information supplied on the curricula vitae of the candidates prior to the interviews, competent people serving on the selection panels and more stringent minimum criteria for eligibility for senior posts.een conducted.
