An Investigation of the Relationship Between Grades and Learning Mode in an English Composition Course
Authors: Bourdeau Debra , Griffith Kelly , Griffith John , Griffith John
Published: August 2021

The education community has conducted studies on failure rates and withdrawal rates between learning modalities in the past, but few studies have evaluated grade distribution between learning modes or focused specifically on English Composition. Using 2,919 student grades from the 2015 – 2016 academic year for an English Composition course, researchers examined failure rates, grade distribution, and withdrawal rates between In-Person learning, Online learning, and Synchronous video learning modes. In this study, learning modes and failure rates were related. Synchronous video modes of instruction had higher failure rates than traditional In-Person classes. Synchronous video classroom students failed at a higher rate than online students. Grade distributions showed significant differences based on learning mode. In-Person students earned more Bs and fewer Cs, Ds, and Fs than Online and synchronous video classroom students. In-Person students also withdrew at a significantly lower rate than online students. With these findings, we suggest that finding the root cause and alleviating the differences in student performance across learning modes should be a high priority for the educational community.
Increasing access to professional learning for academic staff through open educational resources and authentic design
Authors: Wilson Gail , Myatt Paula , Purdy Jonathan
Published: August 2021

This research examines the design and delivery of a new Foundations of University Teaching Practice (FUTP) program delivered through asynchronous online modules. The freedom to choose defines the new momentum of openness in distance and open learning. University teaching staff expect quality resources to support their professional development within the reality of limited time for learning and a desire for increased accessibility. Openness and increased access bring both opportunities and challenges. This paper uses mixed methods to examine the FUTP from the perspectives of both the designers and the academic staff who participated in the program. Using personal reflections, focus groups, a survey, and interviews, we explore those opportunities and challenges within the context of the design and delivery of the program and report on the findings. Our research confirmed the value of openness and increased access to professional learning in higher education
An Academic’s Role? Supporting Student Wellbeing in Pre-university Enabling Programs
Authors: Crawford Nicole , Johns Susan
Published: August 2021

Student wellbeing and mental health are increasingly a concern of universities. Most universities provide central counselling services and, in recent years, some have introduced wellbeing programs. However, an unrecognised source of support and pastoral care for students is academic staff. This pilot research project explored the experiences of academic staff in one university’s enabling programs in terms of the type of support academic staff provide (academic and/or non-academic), how equipped they perceive they are to support their students, and how this role impacts on them. The study is qualitative; interviews were conducted and a thematic analysis undertaken. It was found that academic staff viewed supporting their students as part of their role, particularly due to the diverse and complex nature of the cohort, and noted that students sought support from them for academic and non-academic issues because they had a rapport with them, trust and regular contact. A positive finding was that the academic staff had clear boundaries and lines of referral, which means they were not taking on pseudo-counselling roles. How equipped staff perceived they were and how the support role impacted on them varied depending on their teaching role. The findings in this exploratory study prompt a re-conceptualisation of the academic role. The article proposes a model of support that is holistic, student and course centred, and that integrates the centrally-located university counsellors. Furthermore, it posits that at the core of the enabling programs is a philosophy of care.

The transformative power of digital humanities in teaching family history online
Authors: Harman Kristyn
Published: August 2021

This paper explores the transformative power of digital humanities in teaching family history online to large cohorts of Australian domestic students. It takes as a case study a unit developed specifically for students to learn about how to research their convict ancestors’ lives and how to situate their ancestors’ lived experiences within relevant wider contexts. Its focus is twofold. The convergence of rapidly expanding digital repositories and databases of family history-related information and increasingly sophisticated online teaching platforms and how this has facilitated a shift from face-to-face to fully online learning and teaching is examined. The ways in which this transformative change was engineered through the unit design, delivery, and evaluative processes are then canvassed. The case study demonstrates how, with thoughtful, well-structured, and innovative approaches to design and by adopting a bespoke delivery model for online delivery, students can readily learn to access and engage critically with extensive online resources and can be equipped with the digital tools to use these optimally and to their satisfaction.
An Integrated Evaluation Model of Teaching and Learning
Authors: Lu Yi-Ling , Wu Chih-Wei
Published: August 2021

Knowledge transmission and knowledge construction are two common approaches adopted for teaching and learning in higher education. Applying the two different approaches, this paper developed an evaluation model of teaching and learning, which comprises three main conceptual blocks: teaching, learning and learning assistance. A quantitative survey was utilised, collecting data from the Student Assessment of Learning Gains (SALG) along with the Student Evaluation of Teaching (SET) from 108 randomly selected courses at a university in Taiwan. The results demonstrated an R² value of 0.794. The route between teaching and learning was not statistically significant (t=0.0359), indicating that knowledge is constructed in the mind of the student with learning assistance as the mediator.
Research skill development spanning higher education: Critiques, curricula and connections
Authors: Willison John
Published: August 2021

The Research Skill Development (RSD) framework was devised in 2006 to articulate what educators do when they facilitate student learning through active exploration in ways that enable their skills to grow in sophistication and rigour. This special issue of JUTLP comprises eight articles that focus on the critique, adaptation and application of the RSD. This article introduces the special issue and presents the 2018 version of the RSD, in response to 12 years of feedback on the framework. Changes in the RSD include improvements in articulation of the facets of research, better delineation of autonomy, and the addition of the affective domain and guiding questions.
Of the other seven articles, five are set in the undergraduate years and two in master’s, with contexts including biology, education, engineering, humanities and interdisciplinary studies. The articles are based across diverse settings, including laboratory, online, language and workplace learning. Of these seven, one critiques the RSD, three focus on curriculum design and three connect the RSD to enduring issues of current concern by adapting the framework for academic literacy, work skills and problem solving. These three adaptations are examples of numerous emerging models that modify RSD terminology and shape, within its broad parameters, and are introduced in this issue as the Models of Engaged Learning and Teaching (MELT).

Authors: Jacobsen Michele , McDermott Mairi , Brown Barbara , Eaton Sarah Elaine , Simmons Marlon
Published: August 2021

The purpose of this research was to better understand graduate students' learning experiences in a research-intensive, online Master of Education (MEd) program. In alignment with the program goal for graduate scholars of the profession, this course-based program adopted an inquiry-based signature pedagogy grounded in the innovative practice of research-based learning. As part of this study, we explored broader program structures, including the cohort-based model, course sequencing and research ethics approval processes, which situate the research-based learning experiences. Several research questions framed our investigation into the experiences of online students who are engaged in a research-active MEd program. Analysis of survey and focus group information contributes to this mixed-methods case study and provides insights into implications for research-based learning in online course-based graduate programs.
Student engineers optimising problem solving and research skills
Authors: Missingham Dorothy , Shah Siddarth , Sabir Fizza , Willison John
Published: August 2021

Problem solving and researching are connected activities in the engineering profession and across education. The empirical research presented in this paper considered the effectiveness for teaching and learning of a model that was based on this connection and derived from the parameters of the Research Skill Development framework. The model, devised by students for students, is called the Optimising Problem Solving (OPS) pentagon, and was piloted in a large first-year engineering course in 2014-2015 and in another university in the first half of 2016. This article presents data from formal research conducted on the 2016 offering of the course gathered from pre (n=221) and post (n=169) surveys, and semi-structured interviews of students (n=5) and student/tutors (n=5) sixteen months after course completion. Statistically significant (p < 0.01) changes from pre to post in items with medium to large effect sizes provided student perspectives on which problem-solving skills improved, and the interview data provided rich detail on the nature of changes and how these changes were effected. For the 2016 cohort studied, our evidence suggests that use of the OPS pentagon was associated with improved student problem-solving skills, and tutors’ capacity to teach problem solving.

Aligning Information Literacy Assessment with Metacognitive Strategies
Authors: Hostetler Kirsten , Luo Tian , Stefaniak Jill
Published: August 2021

Despite the popularity of metacognitive research, and the inclusion of similar concepts in professional guidelines, librarians have not incorporated metacognitive tools into their assessment strategies. This systematic literature review found (1) metacognitive assessments can act as a learning aide in encouraging higher-order thinking; (2) metacognitive assessments can be effective measurements under proper conditions with experienced learners; and (3) librarians have limited options when selecting assessment tools even as the demand for demonstrating the library’s value to stakeholders is increasing. The paper concludes with gaps in the literature and areas for future directions.
The role of self-determination theory in developing curriculum for flipped classroom learning: A Case Study of First-Year Business Undergraduate Course
Authors: Narendran Roshni , Almeida Shamika , Coombes Rebecca , Hardie Geraldine , Quintana-Smark Eunice , Zaher Nabi , Wang Hui-Ling , Chowdhury Ahabab , Stevenson Barry
Published: August 2021

This study examines the influence of adopting a student-centered active learning approach based on self-determination theory (SDT) to develop independent and motivated first-year Australian business undergraduates. Existing literature demonstrates how active learningapproaches can help to improve student motivation. However, there are no empirical studies to assess the influence of active learningclassroom activities on student academic performance during their first year of tertiary studies. The aim of our study is to contribute to knowledge by integrating self-determination theory, and ‘at-home ethnographic’ research approach to reflect on how active learning-classroom strategies can help tertiary business students become independent learners and improve their academic performance. The active learning-classroom approach included a scaffolded assessment structure; timely and ongoing tutor feedback on assessment criteria and learning outcomes of the scaffolded assessments; and social/peer-based learning activities within and outside of the classroom to support student performance. The authors draw on an ‘at-home ethnographic’ research approach, which allowed the teaching team to use their observations during the 13 weeks of teaching, and team reflections, to describe not only what they witnessed, but also their experiences of how students interacted, and what they did within the classroom environment. The study shows that students became autonomous and positively benefited from the scaffolded assessment structure while evolving to become competent, independent learners due to the continuous feedback they received on their assessments, and to the active peer learning within and outside of the classroom. Moreover, the group assessments provided a platform to engage with academic literature, which, in turn, helped students to challenge their understanding of the concepts by engaging in critical analysis with their peers. The findings can help future tertiary learning designers to develop first year assessments that will support students to become independent learners and reduce the level of attrition during the first year of tertiary education.
Making the case for oracy skills in higher education: practices and opportunities
Authors: Heron Marion
Published: August 2021

In this paper I make the case for embedding oracy practices in the HE curriculum through explicit teaching of oracy skills and a shared common language to describe these skills. Active learning and teaching approaches as well as growing expectations of graduate employability skills have resulted in greater demands on students in UK higher education in terms of their oracy (speaking and listening) skills. Whilst oracy skills have long been the focus of studies in compulsory educational contexts, there is little transfer of research findings to a higher education context. With the aim of opening up the discussion on oracy skills in HE, this paper reports on an exploratory study carried out to investigate how teachers on two undergraduate business modules incorporated oral communication skills in their content, pedagogy and assessment. Data were gathered from observations of lectures and seminars, course documents, and semi-structured interviews with tutors. With reference to an Oracy Skills Framework the paper concludes with suggestions for how oracy skills may be more explicitly embedded into the undergraduate curriculum.
Assessing written communication skills using a Continua Model of a Guide to Making Judgments (GTMJ)
Authors: Grainger Peter , Christie Michael , Carey Michael
Published: August 2021

Written communication skills are one of the most assessed criteria in higher education contexts, especially in humanities disciplines, including teacher education. There is a need to research and develop an assessment grading tool (i.e. criteria sheet or rubric) that would assist students in pre-service teacher education programs to better understand and practice written communication and to assist markers when grading academic essays that include this criterion. When rubrics are used the criterion that covers the written communication skills part of the task is often too general to truly assist students to know what they must do in order to obtain the grade to which they aspire. Using substantive conversation in focus group discussions, we defined written communication and designed a criteria sheet using a model known as the Continua model of a Guide to Making Judgments (GTMJ). We found that this tool not only had the potential to help students to better understand key features of good written communication in an academic context, but also to assist assessors to focus on standards descriptors or ‘threshold’ qualities of written communication when grading students’ academic essays.
Supporting Scholarly Thinking in a Nordic Teacher Education Webinar Practice
Authors: Reneland-Forsman Linda , Magnusson Maria
Published: August 2021

With this study we have a twofold aim. Firstly, to develop a model for identifying and analyzing the status of students' scholarly thinking, and secondly to design and evaluate an educational practice with the aim of supporting these skills. A series of webinars connected researchers and students from Finland, Norway and Sweden and gave the students access to an authentic Network of researchers, otherwise not accessible to them. The webinars were recorded and an analysis, inspired by variation theory, were conducted in order to identify signs of scholarly thinking in student reasoning when discussing students' final thesis. Findings were then used to construct a model for identifying variations of scholarly thinking as qualities of scholarly discernment, identified in students’ communicative actions. Two critical aspects for stimulating scholarly thinking during webinars emerged from data. First the diversity of language and knowledge and secondly, a more informal framing. A carefully staged webinar using these two critical aspects, offers a socialization of students in professional training, to an academic discourse where the production and evaluation of knowledge is part of students’ identity and constantly debated.
Individual Networks of Practice for PhD Research Socialisation
Authors: Watson Todd Richard , Louw Stephen
Published: August 2021

A PhD combines experiential learning of the research process with socialisation into the research community. Studying a PhD is a highly individual experience with each student seeking and receiving different types of support from different agents. In this paper we investigate the experiences of four PhD students at a Humanities faculty at a Thai university through a series of interviews. To account for the unique nature of each student’s experience, we use Individual Networks of Practice (INoPs) as the main method of analysis. The interviews were first analysed by adapting Sala-Bubaré and Castelló's (2016) model of socialisation, identifying the social agents and the content of the experience shared with each agent, and then constructing an INoP (Zappa-Hollman and Duff 2015) map to visually represent each student's social network. These INoPs served to guide a qualitative analysis of the salient issues in the interviews. The INoPs highlight the unique nature of each student's set of agents and experiences, but there are also commonalities across students showing that peers and faculty staff serve as key social agents.
Dictadura de ley siglo XX
Authors: Turcios H. Roberto
Published: August 2021

El artículo aborda la formación de la dictadura del general Maximiliano Hernández Martínez entre 1931 y 1935 y su consagración constitucional en 1939 a la que se refiere el título. Para ello describe el impacto que tuvo la Gran depresión en la economía salvadoreña, así como las repercusiones de la crisis generalizada que experimentó el país y que se manifestó en la reorganización del Estado, la movilización de grupos rebeldes y, más importante, el giro hacia la dictadura como régimen político. Se sugiere que la oposición entre la democracia y el autoritarismo ha resumido la problemática política de la evolución constitucional del siglo XX en El Salvador. Desde un enfoque histórico plantea que la tensión entre esos dos polos creó, de un lado, la formalidad constitucional y, de otro, la realidad de irrespeto a los derechos de la ciudadanía. A lo largo del siglo, la relación entre las luchas por la democracia, la vigencia del autoritarismo y la producción constitucional fueron decisivas en tres periodos: 1939–1944; 1950–1962; 1983–1992. El primer periodo fue del esplendor de la dictadura; el segundo, correspondió a la vigencia autoritaria. En el último, en medio de la guerra, se configuró la fundación de la democracia. Este planteamiento está inscrito en el proyecto más amplio de investigación sobre la «Evolución constitucional salvadoreña en el siglo XX», en el marco de la agenda de investigación de la Universidad Evangélica de El Salvador (UEES), de cara a la celebración del Bicentenario de la Independencia, 1821-2021.
Caracterización socioeconómica de jóvenes migrantes del municipio de San Miguel en El Salvador
Authors: Vaquerano Benavides José Rigoberto , Castro Cruz Pedro Adalberto
Published: August 2021

La migración irregular ha sido un fenómeno socio histórico persistente en los últimos 40 años en El Salvador, motivado fundamentalmente por las difíciles condiciones socioeconómicas y falta de oportunidades laborales. En el país se generan escenarios de exclusión social que impulsan la emigración de muchos ciudadanos que se marchan con la esperanza de obtener prosperidad económica y un entorno sociocultural estable en otros territorios. La migración irregular debe ser abordada desde una perspectiva multicausal y científica, enfocando sus matices económicos, políticos y socioculturales en los que se ven involucrados principalmente los jóvenes; trabajo con enfoque mixto. A partir de las consideraciones mencionadas anteriormente en este artículo se aborda la realidad socioeconómica de jóvenes escolarizados del municipio de San Miguel residentes en zonas urbanas y rurales, se presentan sus expectativas y opiniones respecto a la posibilidad de migrar, las condiciones socioeconómicas y el contexto de inseguridad en que viven; asimismo, experiencias de jóvenes que vivieron de cerca el fenómeno de la migración irregular y volvieron al país en calidad de retornados. Por otra parte, se indagó en el trabajo de asistencia que realizan diversas instituciones que se vinculan medularmente con migrantes y retornados, mediante iniciativas y proyectos socioeconómicos para su reinserción socioeconómica. La aproximación al fenómeno estudiado permitió a los investigadores proponer acciones al gobierno e instituciones de la sociedad en favor de la integridad, dignidad y respeto a los derechos humanos de las personas migrantes y retornadas para implementar estrategias interinstitucionales en materia socioeducativa y laboral que incidan en la prevención de la migración.

Authors: Monroy Bernal Enrique
Published: August 2021

Este artículo analiza desde la perspectiva del derecho penal y el enfoque de género el proceso de investigación que se realiza en sede fiscal sobre el delito de trata de mujeres durante el periodo 2012 a 2019. Se diseñó una metodología aplicada y de análisis descriptivo con enfoque cuantitativo; analizando desde una perspectiva jurídico social, las acciones y resultados obtenidos en la investigación del delito de trata de mujeres a partir de las diferentes herramientas legales. El aporte de esta investigación permite conocer las acciones realizadas por el Estado para recolectar pruebas y desarrollar una persecución del delito. Como parte de los hallazgos se determinó que El Salvador ha mostrado avances en la regulación del delito de trata de personas y el establecimiento de políticas y protocolos de persecución. Sin embargo, los resultados estadísticos del proceso de investigación representan una tendencia baja en la sanción del delito, dificultando así la garantía de los derechos de las víctimas, el acceso a la justicia y favoreciendo la impunidad e inseguridad jurídica.

Glibenclamide is a sulfonylurea class of antidiabetic drugs that works by stimulating insulin secretion in the pancreas so that it is effective only when the β-cells of the pancreas can still produce. The glibenclamide dosage form that is on the market is a conventional oral tablet which has various disadvantages in terms of pharmacokinetics. Based on this, it is necessary to develop a more effective drug delivery system for glibenclamide in order to avoid first-pass metabolism so as to increase the bioavailability of glibenclamide, namely by making mucoadhesive buccal tablets. This glibenclamide mucoadhesive buccal tablet is formulated using a variety of mucoadhesive polymers, namely CMC Na and oleic acid as enhancers. The manufacture of four mucoadhesive buccal tablet formulas used the direct compression method. The results of the weight uniformity test showed that they did not meet the NP requirements specified, all formulas had an NP of more than 15. The tablet hardness test also showed results that did not meet the test requirements. However, the results of the physical properties of the brittleness, pH and swelling index showed the results that met the test requirements. In this research, the optimum variation of CMC Na polymer and oleic acid as enhancers to physical properties (hardness, brittleness, pH, swelling ability) and the release of glibenclamide mucoadhesive tablets were CMC Na of 37.5 mg and oleic acid of 3.5. ml.

Acoustic radiation force imaging (ARFI) in the non-distended bladder does not predict abnormal urodynamic parameters in children
Authors: Streur Courtney S. , Smith Ethan A. , Dillman Jonathan R. , Kraft Kate H.
Published: August 2021

Introduction: Acoustic radiation force imaging (ARFI) is a recently developed form of ultrasound imaging that allows in-vivo measurement of tissue stiffness. This technology could be useful at predicting bladder compliance in children. We hypothesize that tissue stiffness, as measured by ARFI, correlates with abnormal bladder compliance and capacity in patients with bladder dysfunction.

Methods: Patients who presented for cystometrography (CMG) underwent ARFI of the bladder wall. Nine bladder wall shear wave speed (SWS) measurements were acquired using point and 2D ultrasound shear wave elastography. The mean for each ARFI technique was correlated to bladder compliance, calculated using Wahl’s dimensionless number. ARFI parameters also were correlated with bladder capacity.

Results: A total of 25 patients were enrolled. Mean age at time of enrollment was 4.23.9 years (range: 2 months to 15 years). There was no significant correlation between bladder compliance and point shear wave speed measurements (r=-0.22, p=0.31) or 2D shear wave speed measurements (r =-0.35, p=0.1). A total of 19 patients had bladder capacity below EBC. There was no significant correlation between bladder capacity and point shear wave speed measurements (r =-0.08, p=0.7) or 2D shear wave speed measurements (r=-0.36, p=0.09).

Conclusions: Our results did not demonstrate a significant correlation between bladder wall ARFI shear wave measurements and bladder compliance or bladder capacity. Further studies are warranted to determine whether ARFI may be used to predict abnormal urodynamic parameters in children.

Introduction: Although intraoperative iatrogenic ureteric injuries (IUI) are rare, significant consequences can occur if they are unrecognized at the time. The focus of our study is to characterize the associated morbidity and identify predictors of delayed recognition of IUI.

Methods: Sunnybrook Health Sciences Centre Research Ethics Board approved the study. Patients with a diagnosis of IUI between 2002 and 2020 were identified through an institutional electronic medical record system. Data pertaining to the demographic characteristics, diagnosis, and management of IUI and overall outcomes were collected retrospectively.

Results: Of the 103 patients identified, 83% were female, 52% had previous abdominal surgery, and 18% had previous radiation. The median age was 67 (21–88) years. Twenty percent were not recognized at the time of surgery. Although delayed recognition was not a significant predictor for poor outcome after subsequent repair (i.e., hydronephrosis, ureteric stricture/obstruction), it was associated with substantial morbidity to the patient (i.e., additional procedures) and increased cost to the healthcare system (i.e., longer hospital stay, readmission to hospital). Patients who underwent laparoscopic surgery had an 11 times more likely chance of having an unrecognized IUI as compared to those who underwent open surgery (odds ratio 11.515, p=0.0001).

Conclusions: Delayed recognition of IUI may be associated with considerable adverse effects. In this retrospective case series, we identified laparoscopic surgery as a significant predictor for delayed recognition of IUI. This information underscores the need for future studies to facilitate intraoperative identification of ureteric injuries, particularly during laparoscopic procedures.

Introduction: We aimed to assess the outcome of our series of simple prostatectomy using the open simple prostatectomy (OSP) and robotic-assisted simple prostatectomy (RASP) approaches, at our institution.

Methods: A retrospective chart review of men who underwent OSP and RASP at Western University, in London, ON. Preoperative, intraoperative, and postoperative data were collected and analyzed.

Results: From 2012–2020, 29 men underwent a simple prostatectomy at our institution. Eight patients underwent an OSP and 21 patients underwent a RASP. The median age was 69 years. Preoperative median prostate volume was 153 cm3 (range 80–432 cm3). The surgical indications were failed medical treatment, urinary retention, hydronephrosis, cystolithiasis, and recurrent hematuria. The median operative time was 137.5 minutes in OSP and 185 minutes in the robotic approach (p=0.04). Median estimated blood loss was 2300 ml (range 600–4000 ml) and 100 ml (range 50–400 ml) in the open and robotic procedures, respectively (p=0.4). The mean length of hospital stay was shorter in the RASP group, one day vs. three days (z=4.152, p<0.005). Perioperative complication rates were significantly lower in the group undergoing RASP, with no complications recorded in this group (p=0.004). Both groups demonstrated excellent functional results, with most patients reporting complete urinary continence (p=0.8).

Conclusions: We report very good perioperative outcomes, with a minimal risk profile and excellent functional results, leading to marked improvement in patients' symptoms at followup after both the OSP and RASP approaches. RASP was associated with a shorter length of hospital stay, decreased blood loss, and a lower complication rate.

Este artigo apresenta traços da história da educação da criança ao longo do tempo, enfatizando a possibilidade de pensar na contemporaneidade a partir de aspectos filosóficos os (des) encontros da infância na escolarização. A construção se dá a partir de uma pesquisa de inspiração cartográfica realizada com crianças e professoras de um CMEI no interior pernambucano. O estudo destaca a potência da infância ao convidar as docentes a pensar sua prática pedagógica e sua organização, ao questionar a própria vida na escola, convidando, através de seus questionamentos, a interromper a linearidade que, às vezes, as rotinas escolares propõem. Assim, esta pesquisa com crianças traz contribuições para se pensar a história da educação, sobretudo, pensar em um tempo presente.

Plant material obtained by pruning and production of deciduous fruit trees was evaluated as substrates for the production of the oyster mushroom,
Pleurotus ostreatus
. Lignified branches and stems from peach, apple, and pear trees were processed using a ripping machine to reduce the size of chips and to optimize disinfection.

A completely randomized experimental design was proposed with six treatments (novel substrates) and one absolute control (100% hay substrate). Morphological variables such as thickness and diameter of the pileus, stipe length were assessed, as well as production variables (sprouting, fresh weight, and biological efficiency) and bromatological analysis (ash, ethereal extract, crude fiber, and crude protein).

Apart from the 100%-hay substrate, biological efficiency ranged between 27% (100% apple tree as the substrate) and 140% (50% hay + 50% peach tree as the substrate). According to morphological analysis, the highest diameters were recorded from mixed substrates (50% hay + 50% wood), and a highly significant positive correlation was found between diameter and stipe length. Morphological parameters were not significantly correlated with biological efficiency. Analysis of biological efficiency confirmed that mixed substrates clustered together with 100%-wood substrates.

Bromatological analysis showed that the mixed substrate (50% hay + 50% pear tree) had the highest protein content among the novel tested substrates. Bromatological parameters were not significantly correlated with biological efficiency.

In conclusion, pruning residues from fruit trees can be valuable by using them as substrates for the cultivation of
P. ostreatus
. Production is quantitatively competitive with that using hay, on the condition that wood is mixed with hay.
Avaliação Experimental da Escalabilidade de Sistemas P2P e um Novo Algoritmo de Controle de Taxas de Upload
Authors: Mendes Diego , de Souza e Silva Edmundo

Estudos recentes mostram que nem sempre sistemas P2P são escaláveis, o que é evidenciado por um fenômeno chamado de "síndrome do pedaço faltante". Tal síndrome ocorre quando a grande maioria dos peers possui todos os pedaços do arquivo sendo obtido, exceto um deles, comum a todos esses peers. Nesse cenário a vazão do sistema é comprometida. Esse fenômeno foi detectado e estudado na literatura a partir de modelos analíticos. Entretanto, não existem resultados mostrando que o problema ocorre em situações práticas. Nesse contexto este trabalho possui dois objetivos. O primeiro é o de captar a existência dessa síndrome a partir de experimentação utilizando um protocolo real de sistemas P2P (BitTorrent). Do nosso conhecimento essa é a primeira abordagem nesta direção. O segundo é o de propor um novo algoritmo de controle de taxas de upload com o objetivo de aliviar o problema. Através de modelos analíticos avaliamos as vantagens e desvantagens da nova estratégia.

Globalization and advanced manufacturing technologies have forced manufacturing firms to increase productivity while reducing costs. At the same time, customers are increasingly demanding better products considering tangi- ble (e.g., smell, color, taste) and intangible (e.g., mark, fair treading, and envi- ronmental responsability) attributes. Currently, Brazil consolidates a position as the largest producer and exporter of coffee, accounting for 30% of the inter- national coffee market. This paper presents a stochastic model for performance evaluation and planning of coffee manufacturing process aiming at reducing the cost and time of the production cycle. An industrial case study shows the practical usability of the proposed models and techniques.

Cresce cada vez mais a quantidade de cenários e aplicações que necessitam de processamento e respostas em tempo real e que se utilizam de modelos matemáticos e de mineração de dados a fim de garantir o melhor suporte à tomada de decisão. Neste trabalho, propomos uma metodologia para processamento e clusterização de grandes volumes de fluxos, contínuos e infinitos, de dados com respostas em tempo real, através do uso de redes neurais artificiais conhecidas como mapas auto-organizáveis. Os experimentos e simulações foram realizadas em um ambiente de Cloud Computing sobre um conjunto de dados climáticos. Os resultados mostram a eficiência da proposta ao garantir que o modelo neural utilizado possa gerar respostas em tempo real para o processamento de Big Data.
