AN ANALYSIS OF SECONDARY TEACHERS' REASONING WITH PARTICIPATORY SENSING DATA
Authors: GOULD ROBERT , BARGAGLIOTTI ANNA , JOHNSON TERRI
Published: July 2021

Participatory sensing is a data collection method in which communities of people collect and share data to investigate large-scale processes. These data have many features often associated with the big data paradigm: they are rich and multivariate, include non-numeric data, and are collected as determined by an algorithm rather than by traditional experimental designs. While not often found in classrooms, arguably they should be since data with these features are commonly encountered in daily life. Because of this, it is of interest to examine how teachers reason with and about such data. We propose methods for describing progress through a statistical investigation. These methods are demonstrated on two groups of secondary mathematics teachers engaged in a model-eliciting activity centered around participatory sensing data. We employ graphical depictions of discrete Markov chains to describe the strategic decisions the teachers follow while analyzing data, and find that this descriptive technique reveals some suggestive patterns, particularly emphasizing the importance of frequent questioning and crafting productive statistical questions.

DEVELOPING STATISTICAL KNOWLEDGE FOR TEACHING DURING DESIGN-BASED RESEARCH
Authors: GROTH RANDALL E.
Published: July 2021

Statistical knowledge for teaching is not precisely equivalent to statistics subject matter knowledge. Teachers must know how to make statistics understandable to others as well as understand the subject matter themselves. This dual demand on teachers calls for the development of viable teacher education models. This paper offers one such model, which relies upon engaging teachers in design-based research. Teachers collaborate with a researcher to design, implement, and analyze instruction to pursue desired statistical learning outcomes for students. The researcher allows teachers enough autonomy to make and learn from mistakes during the process. Unpacking and addressing the mistakes has value as a means of teacher learning. The model and a specific instance of its implementation are described along with reflections on how productive mistakes during design-based research provide opportunities for fostering the development of statistical knowledge for teaching.

SECONDARY STUDENTS’ CONSIDERATIONS OF VARIABILITY IN MEASUREMENT ACTIVITIES BASED ON AUTHENTIC PRACTICES
Authors: DIERDORP ADRI , BAKKER ARTHUR , BEN-ZVI DANI , MAKAR KATIE
Published: July 2021

Measurement activities were designed in this study on the basis of authentic professional practices in which linear regression is used, to study considerations of variability by students in Grade 12 (aged 17–18). The question addressed in this article is: In what ways do secondary students consider variability within these measurement activities? Analysis of students’ reasoning during these activities in one classroom (N = 13) suggests that students considered variability in four ways: noticing and acknowledging variability, measuring variability, explaining variability, and using investigative strategies to handle variability. We conclude that the measurement tasks based on authentic professional practices helped students to reason with relevant aspects of variability. Finally, we discuss curricular and research implications.

A FLIPPED CLASSROOM MODEL FOR A BIOSTATISTICS SHORT COURSE
Authors: MCLAUGHLIN JACQUELINE E. , KANG ISABELL
Published: July 2021

Effective pedagogical strategies are needed to improve statistical literacy within health sciences education. This paper describes the design, implementation, and evaluation of a highly interactive two-week biostatistics short course using the flipped classroom model in the United States. The course was required for all students at the start of a doctoral degree program with the goal of standardizing student preparation, contextualizing biostatistics to healthcare, and identifying students needing additional help. We focused on basic concepts and methods, their application to healthcare, selection of statistical procedures, and results interpretation. Data indicate that students were actively engaged, perceived the course as useful, and experienced learning gains. After the course, students indicated that they better understood the relevance and applicability of biostatistics and were motivated to learn more.

THE ROLES OF EXPERIENCE, GENDER, AND INDIVIDUAL DIFFERENCES IN STATISTICAL REASONING
Authors: MARTIN NADIA , HUGHES JEFFREY , FUGELSANG JONATHAN
Published: July 2021

We examine the joint effects of gender and experience on statistical reasoning. Participants with various levels of experience in statistics completed the Statistical Reasoning Assessment (Garfield, 2003), along with individual difference measures assessing cognitive ability and thinking dispositions. Although the performance of both genders improved with experience, the gender gap persisted, with males outperforming females across all experience levels. A confirmatory structural equation model assessing the degree to which cognitive ability, thinking dispositions, and gender account for statistical reasoning performance supported the idea that differences in statistical reasoning are not uniquely a matter of cognitive ability. Rather, gender was found to influence statistical reasoning directly, as well as indirectly through its influence on thinking dispositions.

WHEN DO STUDENTS’ ATTITUDES CHANGE? INVESTIGATING STUDENT ATTITUDES AT MIDTERM
Authors: KERBY APRIL T. , WROUGHTON JACQUELINE R.
Published: July 2021

Statistics educators have been investigating how students’ attitudes change in the introductory statistics course for many years. Typically, an overall decrease in mean attitudes over the course has been noted. However, when and how do students’ attitudes change during the term? Do they steadily decrease or is there a point when students’ attitudes might actually be increasing? If so, can instructors use this to their advantage? This research introduced a mid-semester survey of attitudes. We found that students’ attitudes are not necessarily strictly declining from the beginning to the end of the semester. We also found it might be advantageous to follow individual student attitude trends throughout the semester instead of just looking at aggregate mean scores for the different surveys.

SAMPLING IN THE WILD: HOW ATTENTION TO VARIATION SUPPORTS MIDDLE SCHOOL STUDENTS’ SAMPLING PRACTICE
Authors: FORSYTHE MICHELLE E.
Published: July 2021

Sampling is a fundamental practice of many scientific disciplines. However, K–12 students are rarely asked to think critically about sampling decisions. Because of this, open questions remain about how best to support students in this practice. This study explores the emergent sampling practice of two classes of sixth-grade students as they investigate the ecology of a local creek. It draws on student interviews, pre/post-tests, student artifacts, and video recordings of classroom activity to identify and trace shifts in the ways in which students approached collecting data. The findings suggest three ways in which students’ attention to variation within the context of their ecological investigations supported their development of a more sophisticated practice of sampling.

PRESERVICE TEACHERS COMPARING GROUPS WITH TINKERPLOTS—AN EXPLORATORY LABORATORY STUDY
Authors: FRISCHEMEIER DANIEL , BIEHLER ROLF
Published: July 2021

Group comparisons offer students opportunities to reason about many fundamental statistical concepts like center, variation, or distribution. When doing such activities using large, real datasets, technology becomes and essential tool for exploring the data. With its large variety of features and its user-friendly handling, TinkerPlotsTM --as a software for learners and teachers--can facilitate the process of comparing distributions. In this article we focus on eight preservice teachers´  reasoning when comparing groups with TinkerPlots. We present ideas on the design of a course to develop statistical reasoning with TinkerPlots, present a framework to rate learners´  performance when comparing groups with TinkerPlots, and present results of a laboratory study about preservice teachers´  reasoning when comparing groups with TinkerPlots. Findings suggest that the TinkerPlots tool and design of the course supported these preservice teachers´  reasoning and that more learning opportunities are needed to increase their group comparison elements´  repertoire and interpretation in context.

EFFECTS OF QUESTION STEM ON STUDENT DESCRIPTIONS OF HISTOGRAMS
Authors: KAPLAN JENNIFER J. , LYFORD ALEXANDER , JENNINGS JEREMY K.
Published: July 2021

Assessment is necessary, but difficult, in statistics education. Multiple choice assessments are common, particularly for research purposes. Open-ended assessments may be more adept at revealing student understanding, but ensuring their validity can be difficult. The study presented here examines differences in student descriptions of histograms for different question prompts and scenarios in order to understand how best to ask such questions in research and teaching situations. The results show that different ways of asking students to describe histograms and different scenarios and shapes of histograms lead to systematic differences in student descriptions of histograms. The paper concludes with suggestions for phrasing questions, both for research and classroom assessment, and provides directions for future research based on our results.

EVALUATION OF THEORETICAL AND EMPIRICAL CHARACTERISTICS OF THE COMMUNICATION, LANGUAGE, AND STATISTICS SURVEY (CLASS)
Authors: WAGLER AMY E. , LESSER LAWRENCE M.
Published: July 2021

The interaction between language and the learning of statistical concepts has been receiving increased attention. The Communication, Language, And Statistics Survey (CLASS) was developed in response to the need to focus on dynamics of language in light of the culturally and linguistically diverse environments of  introductory statistics classrooms. This manuscript presents a cross-cultural evaluation of the characteristics of the CLASS III (third generation of the  instrument) and provides a user-friendly cross-culturally valid version of the CLASS. Mixed methods are employed to investigate further characteristics of the CLASS III and provide a scale (CLASS IV) that may be utilized in diverse settings. These research results have implications for instructors, professional developers, and researchers to improve instruction with culturally and linguistically diverse  student populations.

SUCCESSFUL SERVICE-LEARNING FOR STATISTICS STUDENTS STUDYING SURVEY SAMPLING
Authors: DOEHLER KIRSTEN
Published: July 2021

This paper explores the implementation of service-learning projects in a survey sampling statistics course. In these projects, students worked with a community partner to develop and administer a survey, analyze the data collected, and present the results. A study with 23 participants was  conducted to investigate whether students’ attitudes towards community service changed after involvement in a statistical consulting-based service-learning project with a local non-profit organization. Results from  administering the Community Service Attitudes Scale (Shiarella, McCarthy, & Tucker, 2000) before and after the project indicated significant changes in several aspects of attitudes towards service. Qualitative information is also provided on themes from student reflection assignments. Project details and recommendations for instructors administering this type of service-learning project are discussed.

STUDENTS’ PERCEPTIONS OF THE FUTURE RELEVANCE OF STATISTICS AFTER COMPLETING AN ONLINE INTRODUCTORY STATISTICS COURSE
Authors: SONGSORE EMMANUEL , WHITE BETHANY J. G.
Published: July 2021

Statistics educators have long recognized the importance of empowering students with statistical thinking skills that could be applied beyond the classroom. However, there is a dearth of research on how students deem statistical topics as having practical future relevance after they complete introductory courses. Focusing on student interest in and perceived value of statistics, this study reports findings from a qualitative study that examined students’ written reflections to explore the nature and extent of the perceived future relevance of statistics among undergraduate students who completed a first-year introductory statistics course online. Findings show that students deemed statistics topics as important if they could be applied to their everyday lives or their academic- and career-related interests. We conclude with recommendations for instructors of introductory statistics courses that enroll students with diverse interests and goals.

ASSESSING STATISTICAL LITERACY AND STATISTICAL REASONING: THE REALI INSTRUMENT
Authors: SABBAG ANELISE , GARFIELD JOAN , ZIEFFLER ANDREW
Published: July 2021

Statistical literacy and statistical reasoning are important learning goals that instructors aim to develop in statistics students. However, there is a lack of clarity regarding the relationship among these learning goals and to what extent they overlap. The REasoning and Literacy Instrument (REALI) was designed to concurrently measure statistical literacy and reasoning. This paper reports the development process of the REALI assessment, which included test blueprint, expert review, item categorization, pilot and field testing, and data analysis to identify what measurement model best represents the constructs of statistical literacy and reasoning given the criteria of fit and parsimony. The results suggested that statistical literacy and reasoning can be measured effectively by the REALI assessment with high score precision.

A MEASURE OF BASIC MATH SKILLS FOR USE WITH UNDERGRADUATE STATISTICS STUDENTS: THE MACS
Authors: RABIN LAURA , FINK LAUREN , KRISHNAN ANJALI , FOGEL JOSHUA , BERMAN LORIN , BERGDOLL ROSE
Published: July 2021

Mathematical competency is related to performance in introductory statistics courses and may be a roadblock to successful course completion. We developed a new measure (Math Assessment for College Students, MACS) of basic mathematics skills that improves upon measures previously used in undergraduate settings. The MACS is freely available and contains items not typically included on standardized measures of mathematical ability. We administered the 44-item MACS to 414 undergraduate psychology statistics students, and used a multiple correspondence analysis to eliminate 14 items, resulting in a 30-item measure with strong psychometric properties. MACS scores showed statistically significant moderate correlations with a commonly used standardized measure of basic mathematics skills and with overall statistics course grade. We discuss the utility of the MACS and how the MACS may help course instructors identify areas of mathematical deficiency that require remediation.

Confronting the challenge of immigrant student underachievement: A comparative analysis of education policies and programs in Canada, New Zealand and England
Authors: Volante Louis , Klinger Don A. , Siegel Melissa
Published: July 2021

Immigrant students consistently demonstrate a performance disadvantage when one considers their achievement against non-immigrant peers. These disadvantages vary across international jurisdictions, suggesting that education system level policies or programs may help to ameliorate or worsen these differences. Our work provides a synthesis of trends from education policies and programs that appear to be associated with more favourable immigrant student achievement outcomes, highlighting three international jurisdictions: Canada, New Zealand, and England. This comparative analysis identifies key features of these education systems that have been associated with the success of their immigrant students. We conclude with a critical view on simple policy borrowing and call for contextually responsive adaptation of promising policies and programs within distinct education systems.

Authors: Romero-Sánchez Guadalupe
Published: July 2021

Esta investigación tiene como objetivo principal realizar una reconstrucción de la actividad llevada a cabo por el oficial Juan de Robles en el territorio central neogranadino a fin de comprender su papel en la definición de un modelo constructivo más sólido y con garantías de calidad y permanencia. Este propósito fundamental implica además comprender la situación de precariedad de los templos de doctrina en el siglo XVI, reflexionar sobre la incidencia de la  falta de albañiles y carpinteros en suelo neogranadino y determinar las acciones que llevaron a la definición del modelo constructivo e identificar a sus actores. Estos objetivos se concretan en la definición de un método de investigación histórica tradicional, fundamentado en lo analítico-sintético, en el que se parte de  lo inductivo para el conocimiento de los hechos particulares como vehículo para el establecimiento de conclusiones generales. Conclusiones que certifican que las condiciones para el remate de las obras y la definición última del modelo constructivo de estos templos fueron impulsadas por Robles.
El modelo arquitectónico de iglesia misionera jesuita en el Virreinato del Perú
Authors: Kubiak Ewa
Published: July 2021

En el Virreinato del Perú existía la arquitectura jesuita que se puede describir como misionera y funcionó en varios ámbitos. Estamos hablando de templos de formas simples que los jesuitas construyeron en lugares donde la nueva fe recién se estaba introduciendo. Dicha arquitectura estaba determinada principalmente por su función, no sufriendo tantas modificaciones regionales, aunque algunos elementos decorativos y algunas variantes de la composición se pueden calificar como soluciones locales. En la ponencia quisiera presentar ambos aspectos mencionados, tanto encontrar los elementos globales de la arquitectura misionera de los jesuitas como destacar su diversidad en las regiones. Me gustaría caracterizar diferentes aspectos como: el mismo proceso de la construcción, la sobrevivencia de la tradición indígena, el uso de las formas y materiales, y también en la variedad de sus decoraciones.  En este análisis quisiera centrarme en ejemplos de arquitectura creada por la Compañía de Jesús, en Colombia (Tópaga, Fontibón), Perú (Andahuaylillas y Juli), Bolivia (indios Mojos y Chiquitos), en las famosas misiones guaraníes en la actual Argentina, Paraguay y Brasil, y también en la arquitectura misionera de Chiloé.

Sistemul nu reușește să dezvolte cunoștințele economice ale studenților și, prin urmare, mobilitatea academică este, de asemenea, foarte limitată. Acest articol încearcă să propună un model multidisciplinar pentru îmbunătățirea sistemului de învățământ care ar încorpora și mobilitatea academică internațională.
The challenges of the Transnistrian conflict for national security and the European development vector of the Republic of Moldova
Authors:   Institute of International Relations from Moldova, Ciobanu Natalia
Published: July 2021

In this study, the author intends to investigate the possible threats that affect the national security of the Republic of Moldova in the context of the Russian Federation’s ignorance of the state neutrality status, as explained by the delay in the process of political Regulation of the Transnistrian conflict, caused by the illegal existence of Russian military forces, funding of illegitimate institutions and separatist military structures on the left bank of the Dniester, including providing weapons and military equipment. Looking into these issues, the author particularly stresses that the process of strengthening the stability and security of a vulnerable state on the inside is painstaking and requires efforts both from state institutions, the whole society and international support. In this regard, the Republic of Moldova has undertaken to deepen its relations with the European Union by signing the Association Agreement in June 2014, which provides inter alia for the enhancement of forms of cooperation focused on common interests in the field of security promotion, defense cooperation and crisis management. By this, Moldova has accepted the challenges of aligning to the standards of development of the Community, while also benefiting from the support on behalf of development partners in a variety of domains: political, economic, social, etc. In conclusion, the author notes that in the course of cooperation, it is relevant for the European Union to ensure its security. Thus, the national interests of the Republic of Moldova in relation to certain risks and threats to national security converge with those of the Union. The European Union is politically and financially supportive of the actions that are undertaken to clarify them, but the institutions of the Moldovan State are exclusively responsible for the results of these actions/inactions.

The number of Romanians all over is currently estimated at almost 10 million - including both Romanians living in diaspora communities and those who live in the historical / traditional communities of the countries in the vicinity of Romania. The official statistics of Romania and of other states or those of international institutions are useful indicators, but they do not reflect the real statistics, either because of the periodicity with which they are carried out, or due to the reluctance of the authorities towards the presentation of real figures on minorities. However, they provide a basis for estimates and for identifying trends.
Conceptual aspects regarding the domicile and residence of the individual (part II)
Authors:   Moldova State University, Curchin Renat
Published: July 2021

The concept of domicile is to be researched in terms of both national and international regulations, because this term does not have the same meaning, or the scope of the term is much wider and should not be identified with the notion of ,,domicile” in the sense of the right to own a dwelling. The importance of establishing the domicile or temporary residence is determined by the legal effects it produces from the point of view of constitutional, civil, criminal, family law, etc. This study, divided into two parts, is an attempt to define the basic terms, identify situations for establishing the domicile in the case of minors, protected persons, rules and exceptions regulated both nationally and internationally.

Role Variations of Performance Measurement in Dutch Local Government
Authors: van Elsacker Willem Jan , ter Bogt Henk J. , van Helden G. Jan
Published: July 2021

This paper examines differences in roles of performance measurement in Dutch local government under diverging contexts – businesslike and political – and varying degrees of standardisation of activities. The research shows that some of these roles apply irrespective of the values of both contingency variables. This holds for the so called standard roles of diagnostic control, influencing future budgets and reporting. However, other roles of performance measurement, especially signalling and learning, only emerge related to specific contextual circumstances. If a policy field is, for instance, highly politically sensitive, these additional roles are important, and can even lead to tight controls. In these circumstances the standard roles also become more pronounced.
Analytical Framework and Student Perceptions: Assessing the Quality of Doctoral Education in Accounting in Ireland
Authors: Ward Anne Marie , Gorman Louise , Brennan Niamh M.
Published: July 2021

To examine the quality of doctoral education in accounting in higher education institutions (HEIs) in Ireland, we develop an analytical framework from the relevant literature and the principles of quality doctoral education included in the Higher Education Authority’s (HEA) National Framework for Doctoral Education (NFDE). Our analytical framework identifies 16 measurable indicators of quality doctoral education classified into four dimensions: context, inputs, processes and outcomes. Compliance with the quality indicators is verified by coding HEI websites and prospectuses. Deeper insights on the indicators of quality doctoral education are obtained from semi-structured interviews with accounting doctoral students. Our findings shed valuable insights on the quality of doctoral education in accounting in an Irish context. Currently, doctoral education in accounting in Ireland is widely available, standardised and consistent with the principles of the NFDE. This suggests a quality doctoral education system in accounting in Ireland. However, our investigation of the individual components of quality identifies areas for improvement.
The One Minute Paper and Assessment Innovation at Third Level: A Teaching Note
Authors: Barnes Edel
Published: July 2021

This paper takes up the increasingly contentious subject of how teachers know and assess what students at third level have learned and know. While research into teaching and learning is developing in institutions of higher education nationally, the extant literature is not extensive. Specifically, instruments such as the One Minute Paper (OMP), which this study has as its focus, are not widely used, even though it is both straightforward to implement and well received by students where research has been undertaken. This study constitutes a teaching note that reflects on the usefulness of introducing the OMP to enhance the effectiveness of lectures in terms of developing student learning. It concludes that the innovation contributes substantially to students’ ability to develop their own sense of meaning and identification with lecture topics and, in this case, resulted in a noteworthy improvement in student performance in summative examinations.
NPM and Performance Measurement: A Comparative Study of the Public Sectors in Ireland and the UK
Authors: Hyndman Noel , McGeough Francis
Published: July 2021

The use of quantitative, often non-financial, targets and performance measures by businesses and not-for-profit organisations has recently received increasing attention in the academic literature. In the public sector this has been particularly driven by the rise and influence of New Public Management (NPM), resulting in a shift from issues of policy to issues of management, and the break-up of traditional bureaucratic structures. One aspect of these changes is an increasing focus on quantitative measures of performance as a support for better decision making and more appropriate accountability in the public sector. Driven by the NPM agenda, public sector organisations have sought to develop targets that cover all aspects of an organisation’s performance. However, the extent to which such an agenda and focus has impacted varies between countries. This paper seeks to examine the possible role of quantitative targets and measures in public sector organisations in general and, through an exploratory study of annual reports, the nature and breadth of the usage of tar- gets and measures are examined in a comparative study of Ireland and the UK. What is found are significantly different intensities of application between the countries, with the UK applying such ideas in a much more rigorous manner than Ireland. Possible reasons for this are suggested.

Evaluation of Low-Carbon Sustainable Technologies in Agriculture Sector through Grey Ordinal Priority Approach
Authors: Islam Shajedul
Published: July 2021

The agriculture sector plays a vital role in the economy, society, and environment, the three dimensions of sustainability. The agriculture sector contributes 12% to 14% of global greenhouse gas (GHG) emissions to the atmosphere, negatively impacting climate change. Using low-carbon and sustainable agricultural technologies can help mitigate climate change and global food security issues. But selecting and prioritizing the best technologies among all alternatives has always been an issue for decision-makers because of various uncertainty related to the agricultural sector. Therefore, the current study intends to identify and prioritize the key low-carbon and sustainable agricultural technologies. The current study makes a pioneering attempt in employing the Grey Ordinal Priority Approach (OPA-G), a modern multi-attribute decision-making technique, for the evaluation of low-carbon and sustainable technologies for the agricultural sector.
Development and Validation of Overset Methods in PyFR
Authors: Wang Lai
Published: July 2021

Overset methods enable us to effectively simulate problems with moving geometries, such as turbines and flapping wings. With rapid advances in high performance architectures, such as graphics processing units (GPU), a new type of parallel direct cut method was recently developed by Crabill et al., which foresees the applications of flux reconstruction methods with the overset capability to implicit large eddy simulation (ILES) of turbines, rotorcrafts, etc., which operate at moderate Reynolds number. We will talk about the integration of the parallel direct cut method into PyFR, especially for the GPU backend, coupled with the arbitrary Lagrangian-Eulerian method for moving objects. Both inviscid and viscous benchmark cases will be used to validate the developed methods.
Biological information as the basis for strategies to manage alien forest pest species = Información biológica como base para estrategias de manejo de plagas forestales exóticas
Authors: Liebhold Andrew , Tobin Patrick
Published: July 2021

Las invasiones por destructivas plagas forestales exóticas están ocurriendo a una tasa creciente. Las especies invasoras provocan diversos impactos sobre los procesos de los ecosistemas forestales y algunas restringen severamente el manejo sustentable del bosque para productos específicos. En el documento se discute el estado del conocimiento sobre como actúa la biología poblacional durante las fases del ingreso, establecimiento y expansión de la invasión biológica y se discute como usar esta información para optimizar estrategias de manejo de plagas forestales. Particularmente se analiza como la información relacionada con las vias de invasión puede usarse para formular estrategias de exclusión. Adicionalmente se discute el rol del "efecto Allee" durante el establecimiento y crecimiento inicial de la población invasora y como el conocimiento de esta población puede usarse para optimizar su detección y erradicación. Finalmente se discute el estado actual del conocimiento sobre la biología de la expansión de la población y como esta información se puede usar en programas para frenar a las poblaciones de especies invasoras. El enfoque destaca el uso de conceptos matemáticos de biología de poblaciones en la predicción de ataques y formulación de estrategias de manejo.
Modelación de la dinámica Plaga-Parasitoide-Bosque mediante autómatas celulares
Authors: Barros Arenas Valentín Eugenio , Gilabert P. Horacio

Se presenta un modelo que simula la dinámica de una población plaga genérica basada en un sistema de autómatas celulares que permite predecir la densidad de la plaga en el tiempo y espacio. Se asumió que el crecimiento de la plaga se encuentra limitado a la disponibilidad de recurso alimenticio disponible en el bosque y a la presencia de parasitoides, que fue cuantificado mediante el modelo dinámico hospedero-parasitoide de Beddington et al. (1978), el cual es modificado incorporándole la espacialidad y dispersión de ambas poblaciones. La aplicación del modelo propuesto se realizó a un caso teórico, simulándose dos escenarios; en el primero de ellos la plaga crece y se dispersa en ausencia de parasitoides, mientras que en el segundo escenario se libera individuos de parasitoides cuando la densidad de la plaga alcanza una densidad umbral. Si bien al finalizar la simulación no se llegó a un equilibrio para ambas poblaciones, los resultados demostraron que la liberación de parasitoides reduce la densidad y tasa de dispersión de la plaga, invadiendo una menor área en comparación con el primer escenario.

Efectos del aprovechamiento sobre la estabilidad de los bosques de Lenga (Nothofagus pumilio) en Tierra del Fuego = Effects of harvest on the stability of Lenga forests in Tierra del Fuego
Authors: Bava José Omar , López Bernal Pablo
Published: July 2021

Actualmente se plantea manejar los bosques de lenga de Tierra del Fuego con cortas de selección en grupos. Sin embargo, este tipo de manejo, que basa su éxito en la recuperación del volumen maderable a partir de los árboles remanentes, podría fracasar si el rodal sufre excesivos daños posteriores a la corta. Por ello se analizó el porcentaje de pérdidas (por caídas o mortalidad) posteriores al aprovechamiento en 60 parcelas de distintas estructuras y calidades de sitio, donde se estimaron los parámetros del bosque al momento de la corta y la intensidad de la misma, en términos de volumen maderable y porcentaje del área basal (AB) original extraída.
