Este trabajo tiene como principal objetivo identificar y comprender, desde una perspectiva sociolingüística, las actitudes hacia el “portuñol” que se utilizan en la provincia argentina de Misiones. Para ello, se expondrán posibles definiciones del término “portuñol”, de manera a que se pueda llegar al lugar acorde con el contexto fronterizo en el que se hace este uso y que será parte del eje temático del presente trabajo. Realizado este mapeo socio-histórico de la provincia y dada una definición del término utilizado en esta investigación, se propondrán los estudios de las actitudes lingüísticas de Ralph Fasold (1996) y sus modelos investigativos, además de su apoyo teórico que contribuirá a una propuesta de diagnóstico sobre el funcionamiento de estos fenómenos en un contexto social de intercambios culturales y lingüísticos: la zona fronteriza. Las actitudes lingüísticas se dirigen a este contexto fronterizo con el fin de identificar el comportamiento de la sociedad misionera ante un uso que, según estudiosos de la lengua, como Amable (2012) y Elizaicín, Behares & Barrios (1993), tiene su origen lingüístico brasileño.

The present PHD thesis is intended to understand the formal aspects of colonial society. In this sense, Alexandre of Gusmão appears in this survey as a man whose ability to pedagogical application manifested in the founding of the Seminary of the Belém of Cachoeira. But for he found the Seminar there was an influence, an inspiration that led to this project. Starting from the Council of Trent and understanding as Alexandre of Gusmão sought the Founder of the Society of Jesus (Ignasio of Loyola) and jesuit intellectual enthusiasm for the project, unveils a tangle of strands, which enables the analysis not only of Alexandre of Gusmão, but of all the colonial context. Thus, we understand that Alexandre of Gusmão is a product of the educational constitution that has occurred in Brazilian lands; history of pedagogy that firm by the numbers of colleges founded by the jesuits relation with the metropolis. As the jesuits cultivated Luso-European Culture, by way of rationalizing the world, how come a pedagogical possibilities of application in the documents guided the Society of Jesus. Anyway, not only the intellectuals of the Society of Jesus, but the documents, the Ratio Studiorum and the Constitutions of the Society of Jesus, inspired Alexandre of Gusmão which adopts and creates, along with Manuel Correia As Regras do Seminário de Belém da Cachoeira forming the basis of a statute that would be applied by Alexandre of Gusmão to educate boys in Brasílica Colony. His whole way of seeing the school world, the rules for students, teacher, functionary, hours of visits, vacations and recreation, religious ritual, masses, reflection, etc, lead to practice good manners.

The present study aims to analyze the reduction of the wage differential by schooling in Brazil between 2001 and 2012, using the PNAD data. Although the positive relation betwee n years of schooling and earnings in the labor m arket persists, recent research on Brazilian show s that wage differentials by schooling have been falling during the past decade. Factors such as the enrollment increase in higher education (not always with q uality), and the market’s absorption of students with low productivity – or even a combination of these factors – may explain the wage differential fall. The study’s hypothesis is that the low quality of Brazilian education offers low skilled labors to the market, resulting in low productivity and lower wages even with a diploma. Using the Oaxaca - Blinder decomposition , the recent fall i n the wage differentials has been proven , as well as the returns to education. One can conclude that th e wage differentials by years of schooling in Brazil can be explained by productivity differentials, however it is not possible to identify the relationshi p between educational quality and labor productivity since the mean wages increased during the analyzed years. Therefore, the hypothesis of this study can only be partly confirmed.

The Homes for the Aged may influence the quality of life (QOL) of the patients. However, there is a paucity of literature on specific instruments that assess the quality of life of older people in these contexts. The aim of this study was to culturally adapt the instrument Quality of Life Scales for Nursing Home Residents for the brazilian context. The scale has 54 items in total and includes eleven domains answered in the form of Likert scale and is used to assess the social and psychological aspects of QOL of patients. It is a methodological research, which followed the steps described in the literature on translation and adaptation of instruments: translation; synthesis of translations; back translation; review by a committee of judges and pretesting. The initial translation was developed by two independent qualified translators who investigated and corrected errors of interpretations and of ambiguous terms in the original language. Both translators and researchers conducted a synthesis of the results of the translations. In the back translation, the consensual translated version of the instrument was again passed into the original language (American English). In the next step, a review by a committee of judges aimed to produce a final version, modified and adapted after review and comparison of all translations performed. Likert scale was used for each item of the scale and calculated the Content Validity Index (CVI) in order to produce the final version and adapted. Items that had Validity Index (CVI) of 0.80 were reviewed again by experts. In the last step, the pre-test, the instrument was administered to 15 elderly patients in Homes for the Aged in order to confirm understanding, clarity of all questions in this sample. This step was developed in long-stay institutions for the elderly in a city in the state of São Paulo, in 2013. The Quality of Life Scales for Nursing Home Residents was translated and adapted to the brazilian context. The application of the instrument through the sample of institutionalized elderly showed clarity and understanding of all the items of the instrument.

Considering the hypothesis which says that the person responsible for people education is also being educated and modified during the teaching and learning processes along with individuals this person is teaching, this investigation aims to identify how the lecturer-facilitators from the “Clinical Governance in Health Regions” specialization understood their educational practice. The facilitators were simultaneously teachers from the “Clinical Governance in Health Regions” specialization and students from the “Health Educational Processes” specialization. Both specializations were built through a partnership between the Health Ministry – MS – and the Sírio-Libanês Teaching and Research Institute – IEP/HSL, being developed during the years of 2011 and 2012 in 10 Brazilian regions, indicated by MS. The courses utilized a constructivist approach and were guided by active methods of teaching and learning. The investigation was based upon the research qualitative principles and utilized the lecturer-facilitators Conclusion Course Thesis as the main source of data analysis. Among the thesis, the facilitators’ educational practice was reported in reflective synthesis about their teaching and learning trajectory. In order to interpret the data a thematic content analysis was applied. Two analytical categories was considered: Educational Practice and Health Care Practice. From those two categories, three thematic was identified: (i) Health professionals’ challenges in graduation and post-graduation; (ii) Building new strategies and educational capacities; (iii) Dialoguing with Clinical Governance elements. The first and the second thematic link to the analytical category “Educational Practice” and the third is linked to the category “Health Care Practice”. A fourth thematic (iv) called “Personal Life Transformations” was linked to the empirical category “Personal Development”. The facilitators’ conclusion course thesis pointed towards the competency profile development proposed by the course, especially to the articulation among educational and heath care practices. Accordingly, the autonomy ideas and construction of new knowledge, from the expansion of listening, respecting others and be tolerant to diversity, permeated all of the thematic. The feelings of discovery, joy and satisfaction reported by the facilitators, associated to the recognition of their own practice transformation point to the educational initiatives power, which integrates theory and practice.

This dissertation discusses the construction of the operational methods in the conveyor belt of sorting recyclable materials in a collectors' cooperative. Cooperatives represent not only a way out of the problems of management of municipal solid waste, but also a possibility of integration and income generation for people who are outside the formal work. Nevertheless, the search for income and better life clashes with precarious working conditions. In this context, the aim of this study is to understand how the cooperative regulate their activity against the difficulties in the conveyor belt of sorting recyclable materials. The applied methodology includes a case study outlined by the Activity Ergonomics. The results indicate both an intense physical and mental effort associated with the collection of recyclable materials. During the activity, the cooperative members face few situations which may affect the objectives and regulate their activity without risking their internal state. Collective joints emerge from the conveyor belt as a possibility of collective regulation of the difficulties arising from the instantaneous overlapping variations (volume, variety and condition of materials) and ascending and descending requirements. These results indicate that the collection of recyclable materials is only possible through the inventiveness of the cooperative members to use perceptual exploration and solve problems facing the pace of work.

The consumption of fruits and vegetables has been growing due to the efforts for a healthier diet. In this context, strawberry can be highlighted for its nutritional value and for being a tasty and attractive fruit. However, on Brazil conditions, for being harvested near its physiological maturity, losses in post-harvest quality are high. Polymeric films containing metal nanoparticles (NPs) have been used in food packaging, once they present properties that contribute in maintaining the quality of fruits and vegetables. For instance, silver nanoparticles (AgNPs) stands out for its antimicrobial action. The goal of this work was to evaluate the post-harvest quality of strawberries packed in polymeric films containing AgNPs and conventional net polymeric films (without NPs). For this purpose, commercial low-density polyethylene films (LDPE) containing AgNPs were characterized by scanning electron microscopy (SEM), Infrared Spectroscopy Fourier Transform (FTIR), thermogravimetry (TGA), Differential Scanning Calorimetry (DSC) and X-Ray Diffraction (XRD), antimicrobial activity tests. For evaluating the films influence on the physical-chemical and microbiological quality of strawberry, the following experiments were performed: (I) strawberry packaged in LDPE and LDPE+AgNP films were stored in cold chamber at 5 and 25 °C for nine days, where physical-chemical and microbiological analyzes were carried out at every three days; (II) Strawberry packaged by LDPE and LDPE+AgNP films were stored in cold chamber at 5 and 25 °C for nine days, and were submitted to the same physicalchemical analysis. To investigate in more details the antimicrobial effects of packaging, two experiments were carried out with strawberry inoculated by E. coli: (III) firstly, strawberry inoculated with E. coli with an initial concentration of 108 CFU mL-1 were stored at 5°C for ten days; subsequently, the physical-chemistry and microbiological analyses were carried out; and (IV) strawberry inoculated with E. coli with an initial concentration at 105 CFU mL-1 were stored at 10°C for ten days; subsequently, the microbiological analyses were carried out at every two days. Adding AgNPs on LDPE matrix did not influence the thermal and physical-chemical properties of films. Films containing AgNPs showed antimicrobial activity against Gram-positive and Gramnegative microrganims. Physical-chemical quality of strawberry was affected mainly by temperature and storage period. AgNPs contained in LDPE packaging was efficient on controlling microbial population growth. Antimicrobial activity and post-harvest quality attained by polyetilene films containing AgNPs may be an indicative for using such Aplicação de filmes com nanopartículas de prata na conservação de morangos type of active packing for other fruits and vegetables, which can help decreasing post harvest losses, and may contribute to improve food safety.

Citrus canker, caused by the bacteria Xanthomonas axonopodis pv. citri (Xac), is a disease that causes serious problems to the global citrus industry, especially to orange(Citrus sinensis). In this regard, this thesis describes the development of new methodologies for the diagnosis of citrus canker by volatile biomarkers or macromolecules produced by the C. sinensis-Xac association, as well, performed the chemical study of the wild strain of bacteria Xac searching to isolate and/or identify chemical compounds that may be associated to pathogenicity. The methods for diagnosis of citrus canker involved: dynamic headspace-GC-MS, HS-SPME/GC-MS and MALDI-TOF/MS. The main volatile biomarker identified by dynamic headspace-GC-MS was isoamyl benzoate and by HS-SPME/GC-MS aromatic compounds (benzaldehyde, phenyl methanol, methyl benzoate, 2-phenyl ethanol, benzyl acetate and ethyl benzoate) when N2 was used in the sample preparation, while without N2, benzothiazole and 2-ethylhexyl benzoate were the main biomarkers. The MALDI-TOF/MS technique was effective to differentiate statistically macromolecules produced by the healthy leaves of C. sinensis when in comparation to symptomatic leaves of citrus canker. The chemical study of Xac allowed the isolation or identification of 15 substances, some of them acting as signaling molecules in other bacteria with genomic similarity. Among the substances are: cyclo (Pro-Leu), cyclo (Pro-Val) and two diastereoisomers of cyclo (Pro-Phe), for which the relative configurations were determined, cyclo (Phe-Phe), quinolin-4-carboxaldehyde, fatty acid amides (octadecanamide, cis-9-octadecenamide, cis-13-docosenamide) and cis-11-methyl-2-dodecenoic acid (signaling molecule in X. campestris pv. campestris). According to several studies in literature, some of these compounds are involved in cell communication of some microorganisms or can be phytoxins released by the bacteria into the plant.
Análise da expressão de proteínas envolvidas no manejo de cálcio cardíaco nos répteis píton (Python molurus), cascavel sul-americana (Crotalus durissus terrificus) e jacaré-de-papo-amarelo (Caiman latirostris) em jejum e nos períodos digestivo e pós-absortivo

The Sarcoplasmic reticulum calcium ATPase (SERCA), phospholamban (PLB) and the Na+-Ca2+ exchanger (NCX) proteins are essential for the cardiac calcium management and myocardial contractility in vertebrates. The increase in metabolic rate generated from mechanical and physiological process of digestion is known as specific dynamic action (SDA) and represents the energy cost of processing, digestion and absorption of food. In several groups of reptiles, feeding generates a rapid increase in rates of gas exchange, whose peak usually occurs one or two days after feeding, before suffering a slower decline and returning to preprandial values. Ingestion of large quantity of food demands a metabolic elevation and leads to indemnities related in ventricular mass and an increase in myocardial force contraction, avoiding an overload on the cardiovascular system. During the fasting, depletion of body mass occurs and it can also reach the heart muscle. To describe the importance and the changes in SERCA2, PLB and NCX proteins on the effects of feeding/digestion in reptiles broad-snouted caiman (Caiman latirostris), burmese phyton (Python molurus) and also by prolonged fasting in South-American rattlesnake (Crotalus durissus terrificus) Western blotting technique was used. We observed the homology existence between the proteins of reptiles in relation to mammals. The SDA increased expression of SERCA2 protein in three species of reptiles. The SDA can also have unduced the expression of an isoform and/or reduced phosphorylation at some active sites of SERCA2 in ventricular tissue of P. molurus. A direct relationship between the expression of SERCA2 with the PLB expression in C. durissus was observed. However in P. molurus and C. latirostris this relation does not exist. The three reptiles expressed the PLB with molecular mass of 50 kDa, whereas the mouse expressed 25 kDa. The vast evolutionary distance that separates mammals of reptiles may have caused the rise of isoforms between these groups, explaining this difference. The increased expression of NCX along with lower expression of SERCA2 and PLB in C. durissus in food group Fasting compared to the other two groups suggests a higher calcium mobilization in this feeding regime, which would be advantageous from the energy point of view. The expression of NCX with different molecular mass between the three species, a smaller number of consensus regions with the animals phylogenetically more distant and the great plasticity of NCX gene to form distinct proteins, suggest the expression of proteins isoforms with the reptiles studied in this research.

Are there successful composting experiences of municipal solid waste (MSW)? Is it possible to have alternative solutions for urban organic waste different from the conventional model of centralized composting plants? Answering these questions was the main objective of this work. The state of São Paulo was the focus of the research. Methodology included a survey of primary and secondary data of centralized and decentralized composting experiences in São Paulo and semi-structured interviews with managers in face to face, telephone or e-mail contacts. Six modalities of composting and fifteen treatment routes of organic waste with source separation had been identified, as well as factors boosting and restricting the development of composting activities in the State. The results showed the diversity of alternatives for organic waste recovery in urban areas, pointed out gaps that benefit final disposal groups and revealed the lack of public support to the composting activities undertaken by several actors in the State. The study concludes that decentralizing activities, diversifying technological routes of composting and stimulating social, public and private entrepreneurs can accelerate the diversion of MSW from landfills and dumps. Such actions can also contribute to urban and rural agriculture and enable implementation of a rational culture of solid waste management.

Metallic coatings are generally designed to confer high wear and corrosion resistance to the substrate to be coated. These properties are essential to make structures suitable to resist to aggressive environment and operating conditions. In this context, Fe-based alloys have drawn great attention due to their unique physical and chemical properties and relatively low cost of iron. Compared with traditional crystalline metallic materials, Fe-based amorphous alloys exhibit high strength, hardness and superior corrosion resistance, attributed to their disorder structures as well as chemical homogeneity. Powder alloys can then be used to produce amorphous coatings on steel substrate, improving corrosion and wear properties in aggressive environments. This work reports on the production of high corrosion and wear resistant coatings produced by HVOF (High Velocity Oxygen Fuel) using only commercials precursors. Initially, preliminary studies were made for the evaluation of glass forming ability (GFA) for the selected Fe60Cr8Nb8B24%at. composition. Further analyses of the crystallization of fully amorphous samples were conducted to correlate the crystalline phases with the physical and chemical properties. Then, the production of amorphous coatings was studied. The microstructure of the samples was characterized by optical microscopy (OM), confocal microscopy (CM), scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray diffraction (XRD) and differential scanning calorimeter (DSC). Corrosion, wear and hardness tests were performed as well as porosity and oxygen content measurements. The results have shown the feasibility of production of high quality coatings by HVOF (low porosity and oxygen content together with high hardness and large amount of amorphous fraction). However, the corrosion properties of the coatings were found to be impaired by the presence of α-Fe and FexB (x=1,2 and 3) crystalline phases.

The concept of relationship between two sets, in particular, the real function of a real variable, is fundamental to mathematics education high school student, it is a basic object of mathematics is elementary and the modeling of many everyday problems or context of other sciences. However, one notes the difficulty of most students understand this concept; stands out, also, the difficulty of students to interpret a function by analyzing its graph in the Cartesian plane xOy. In this context, this thesis try alternative methods that can contribute to the improvement of teaching and learning theme in question. More precisely, it uses Geogebra educational software and the virtual environment Moodle learning for the study of elementary functions. In general, the resources of Geogebra, the Dynamic Geometry and Algebra, have to propitiate to student understands, the proper form, the ratings and the function representation as a curve in the plane; Furthermore, Geogebra allow guesses about the behavior of an elementary function parameters subject to variation. In turn, the use of Moodle environment allows communication and broader evaluation (between teacher-student and student-student) through, questionnaires / online tests, video lessons, discussion forums etc. This text is six classes developed with the participation of two groups (each with about 35 students) of the third year of high school. Initially, in order to detect major and several difficulties, an evaluation (presence) was made with basic issues (of different levels). The performance of these students was quantified, qualified (enjoying the most problematic conceptual topics) and then served as support for the activities - in order to reverse the reality presented and the existing student-mathematical relationship. It is noteworthy that the use of an educational software like GeoGebra already proposes a new dynamic student-teacher-mathematics. Wanted with this change that the student take a more active position on the mathematical content so that, in fact, with proper guidance of the teacher, can understand and demystify the concept of real function of a real variable.

This research aimed to understand how the Green Supply Chain Management (GSCM) is being adopted in small and medium-sized chemical companies. In addition, sought to identify the GSCM practices being adopted by companies in the study and indicate the main pressures (external and internal) for the adoption of these practices. It examine also if the pressures lead to adoption of GSCM practices and if these practices bring improvements in performance (environmental, economic and operational). In order to refine the theoreticalconceptual model of Santa Eulalia, et al. (2011) had conducted a multiple case study in four chemical companies. The companies are small and medium enterprises (SMEs) in the State of São Paulo. The GSCM practices adopted by most companies researched were, respectively, the most adopted for the less practiced, Internal Environmental Management Cooperation with Customers, Green Purchasing, Eco-design and Investment Recovery. The pressures most cited by respondents were, respectively, Regulations, Internal Factor, Marketing, Suppliers and Competitors, and the Society was not considered by any company. It was also found that companies that receive greater pressure to adopt GSCM practices are not always the ones with more practices implemented. However, external and internal factors influencing pressure somewhat implementing GSCM practices. On the performance achieved with the adoption of practices, there is an awareness that bring improved environmental and economic performance. At the same time, the practice can lead to a negative economic impact, especially in the short term. It was also that the positive economic and environmental performance are interrelated. The improvement in operating performance is not perceived by the respondents of the researched companies. Few studies have been found on this issue in national literature, which this study is considered pioneer in research on the theme that analyze the relationships between pressures, practices and performances. Another contribution of the study involves the size of the studied companies, small and medium enterprises (SMEs), since they have few resources, making it difficult to stay in the competitive global market. Studies involving SMEs and to consider its context are relevant to help them gain competitive advantage.

We proposed a new split-merge MCMC algorithm for image segmentation. We describe how an image can be subdivided into multiple disjoint regions, with each region having an associated latent indicator variable. The latent indicator variables are modeled with a prior Gibbs distribution governed by a spatial regularization parameter. Regions with same label define a component. Pixels within a component are distributed according to a Gaussian distribution. We treat the spatial regularization parameter and the number of components K as unknown. To estimate K, the spatial regularization parameter and the component parameters we propose the Metropolised split-merge (MSM) algorithm. The MSM comprises two type of moves. The first one, is a data-driven split-merge move. These movements change the number of components K in the neighborhood K _ 1 and are accepted according to Metropolis-Hastings acceptance probability. After a split-merge step, the component parameters, the spatial regularization parameter and latent allocation variables are updated conditional on K by using the Gibbs sampling, the Metropolis- Hastings and Swendsen-Wang algorithm, respectively. The main advantage of the proposed algorithm is that it is easy to implement and the acceptance probability for split-merge movements depends only of the observed data. The performance of the proposed algorithm is verified using artificial datasets as well as real datasets.

Strategy as Practice (SaP) is a recent theory that appeared at the end of the last century as an approach which assumes the strategy as something that organizations do and not as something that they possess. Based on this premise, its focus is on micro activities carried out by the strategists of different organization s hierarchical levels, called practitioners. They apply theoretical and practical models, called practices, to carry out the strategic praxis. This research was performed based on this approach and seeks to analyze the strategic planning processes adopted by a Federal University in Brazil, considering four consecutive administrations. The main objectives are: to propose a model for the development and monitoring of strategic plans at the Federal Institutions of Higher Education or other public education institutions in Brazil; and to propose a procedure that could facilitate the analysis of their plans. The lack of empirical studies based on the SaP approach or on its applications in studies of planning processes in public universities has been highlighted during the bibliographical research performed in national and international qualified databases, covering publications in journals, books, thesis and dissertations. It was found that the lack of references when one wants to get applications of SaP in universities is even greater. The development of this research took place at the Federal University of São Carlos, based on descriptive case studies of four successive administration cycles each one corresponding to four years. Semi-structured interviews were conducted with the rector and professors who were responsible for coordinating important projects during each administration term. An exam of several documents for each administration cycle was also performed and enabled to collect data and to analyze the processes of formulating and monitoring strategic plans. Each management term was described and analyzed considering five elements: the context (the internal and the external environment) of the institution, the planning (formulation) process, the monitoring process of the plan, the results achieved by management, and the role and activities of the university leader, the rector. The analysis of strategizing processes was carried out based on SaP s constructs: practices, praxis and practitioners. The information obtained in accordance with SaP s constructs was valuable to describe, to comprehend and to compare the planning and monitoring processes implemented in each of the four administration cycles. The study also demonstrates consistent with the literature the importance of rectors roles in formulation and monitoring processes. The main results obtained by the analysis of the four administration cycles supported the proposition of a strategic planning model for Federal Universities and of a series of guidelines and steps to facilitate the analysis of strategic plans, considering the SaP s precepts, in these universities and other related institutions.

This work aimed to facilitate the study of the content of complex numbers for students in the 3rd year of High School, within a focus covering a geometric context, with the use of Geogebra software, combined with notebook student (SÃO PAULO, 2014). The main motivation of this study was to search for an innovative practice, aiming to improve the quality of the teaching-learning process, in relation to the content, since the numerous difficulties demonstrated by students. The theoretical research was based mainly on the theory of representation semiotics registers of Raymond Duval and analysis of curriculum documents for Middle School. Already the methodology was built based on the steps of the Didactics Engineering idealized by Michele Artigue. The production of information involved mathematical activities performed by 31 students of Higher Education of a Civil Engineering course and between 10 to 12 students (there was variation) of a 3rd year of High School; providing the basis for answering the following research issues: I What knowledge about complex numbers, students of Higher Education bring the baggage of high School? II - That prospect of construction of knowledge the notebook of the Student gives the learning of complex numbers? III - The Geogebra can add the construction of knowledge when articulated to the notebook of the Student, made available by the Department of the São Paulo State of Education? The instruments used to collect the amount of information produced by participants, in empirical step of our research were: questionnaire, written records of tasks (protocols) and images of mathematical activities carried out with the help of Geogebra. The results obtained in the analysis of the questionnaires showed that the knowledge of the students in higher education, as well as the students in the middle school, are negligible in relation to the need of those who follow their studies in the field of exact area. With respect to the results obtained from the implementation of tasks for high school students, using the software proved to be efficient for a geometrized viewing the content in relation to construction of its concepts, which allowed students a much better understanding across the studied content.

In this thesis we aim, through the use of a technological tool, the computer, show the possibility of teaching Mathematics causing the student to build their knowledge from concepts presented with the help of software that allow viewing the activities developed. In this sense, we use the GeoGebra software, it is a dynamic geometry software in the public domain and its application to analytic geometry content is easy to learn for the user. Thus, we present a teaching sequence using GeoGebra software in teaching Analytic Geometry, following the contents of the Curriculum Proposal of the State of São Paulo. In each of the proposed activities develop the theoretical content with exercises followed by activity in GeoGebra. At the end of each activity are some of the comments made by students.
