The body donation program at the Federal University of Health Sciences of Porto Alegre: A successful experience in Brazil

The use of dissection to study human anatomy is the foundation for educational excellence among future health professionals, as it offers an ideal opportunity to learn the body's morphology in three dimensions while also providing students with a more humanistic education. The shortage of bodies for dissection, combined with the Brazilian population's lack of knowledge concerning the possibility of voluntarily donating their own bodies, led to the creation of the Body Donation Programs for Education and Research in Anatomy at the Federal University of Health Sciences of Porto Alegre (UFCSPA). The program is based on three pillars: Informing the general public about the program, donor registration, and donation itself. Since the creation of the donor program in 2008, there has been an increase in both the number of donations made during donor's lifetime and the number of bodies received by the university. There has also been a shift in relation to the origin of these bodies, as before the creation of the program most bodies were unclaimed cadavers, while today most of the bodies are sourced from voluntary donations. The initial results regarding the public's acceptance of the possibility of making body donations have been encouraging, as shown by the annual growth in donor registrations. Consequently, the quality and quantity of the material available for educational purposes have greatly improved. Anat Sci Educ. © 2013 American Association of Anatomists.     

Using Plant Clinic Registers to Assess the Quality of Diagnoses and Advice Given to Farmers: A Case Study from Uganda

Abstract

Purpose: This study developed a framework for quality assessment of diagnoses and advice given at plant clinics.

Design/methodology/approach: Clinic registers from five plant clinics in Uganda (2006–2010) were used to develop quality assessment protocols for diagnoses and advice given by plant doctors. Assessment of quality of diagnoses was based on five validation criteria applied on the ten most common crops. Quality of advice was assessed for the four major problems considering efficacy and feasibility.

Findings: The quality of diagnoses varied between crops, from 68% completely validated in maize to 1% in tomato. Complete and partially validated diagnoses were 44% of all queries. The remaining 56% were rejected. Several basic weaknesses were found in data recording and symptom recognition. A greater consistency and precision in naming diseases would increase the number of completely validated diagnoses. The majority of recommendations (82%) were assessed ‘partially effective’. ‘Best practice’ was recommended for 10% and ineffective advice was given in 8% of the cases with considerable variation between diseases.

Practical implications: Plant doctors need more training in symptom recognition, pest management and record keeping as well as better technical backstopping to solve unknown problems. Common standards and procedures for clinic data collection and analysis should be established, and roles and responsibilities clearly defined.

Originality/value: This is the first time plant clinic registers have been used to systematically assess quality of plant clinic services. Apart from being a valuable tool for quality assessment of extension, the plant clinic registers constitute a novel source of regular information about pests, diseases and farmer demand that can help improve decision-making of extension service providers, researchers, plant health authorities as well as information and technology providers.     

Electronic Theses and Dissertations Initiatives: A Survey of University Libraries in Nigeria

The study investigated the extent of adoption of electronic theses and dissertations in university libraries in Nigeria. Data collection for the study was via online questionnaire. The study revealed that digitization of theses and dissertations started between 1980 and 1995. It was found that only a few university libraries have embraced digitization of theses and dissertations in Nigeria. Benefits of electronic theses and dissertations were identified as improving university ranking and visibility, increasing access to the theses and dissertations, saving space in the library, enabling others link to the work with persistent URLs, preserving the work for future generations, and saving costs for students. Challenges such as unstable internet connectivity, lack of funding, irregular power supply, lack of information technology personnel, absence of electronic theses and dissertations submission policy, and copyright issues were identified. It is hoped that the study might provide insights useful for librarians planning to embark on the digitization of theses and dissertations project.     

Quantifying the interdisciplinarity of scientific journals and fields

There is an overall perception of increased interdisciplinarity in science, but this is difficult to confirm quantitatively owing to the lack of adequate methods to evaluate subjective phenomena. This is no different from the difficulties in establishing quantitative relationships in human and social sciences. In this paper we quantified the interdisciplinarity of scientific journals and science fields by using an entropy measurement based on the diversity of the subject categories of journals citing a specific journal. The methodology consisted in building citation networks using the Journal Citation Reports^® database, in which the nodes were journals and edges were established based on citations among journals. The overall network for the 11-year period (1999–2009) studied was small-world and followed a power-law with exponential cutoff distribution with regard to the in-strength. Upon visualizing the network topology an overall structure of the various science fields could be inferred, especially their interconnections. We confirmed quantitatively that science fields are becoming increasingly interdisciplinary, with the degree of interdisplinarity (i.e. entropy) correlating strongly with the in-strength of journals and with the impact factor.     

Traffic modeling for communications networks: A multifractal approach based on few parameters

In this work, in order to model network traffic processes, an efficient multifractal model is proposed based on fewer parameters than other models present in the literature, called 2PEMV. The 2PEMV model (2-Parameter Exponential Modeling for Multipliers’ Variance) is based on a multiplicative cascade in the wavelet domain capable of synthesizing communication network traffic traces which present characteristics such as self-similarity and wide Multifractal Spectrum Width (MSW). For such a purpose, in the 2PEMV model, the energy decay of the wavelet coefficients is captured by means of an exponential modeling for the multipliers’ variance along the cascade scales. The performance of the 2PEMV model to represent the network traffic characteristics is evaluated in comparison to other models present in the literature through simulations that are carried out using real communication network traffic traces.     

Creatine Kinase Activity Weakly Correlates to Volume Completed Following Upper Body Resistance Exercise

In the current study, we examined the relationship between serum creatine kinase (CK) activity following upper body resistance exercise with a 1- or 3-min rest between sets. Twenty men performed two sessions, each consisting of four sets with a 10-repetition maximum load. The results demonstrated significantly greater volume for the 3-min condition (M = 4,156 kg, SD = 867, for 3 min; vs. M = 3,503 kg, SD = 759, for 1 min; p < .001), with no significant differences in delta CK activity between conditions (p = .574). Nevertheless, there was a weak correlation between the delta CK activity and total volume of exercise completed (r = .55 with a 1-min rest, and r =.45 with a 3-min rest). Therefore, the volume following upper body resistance exercise correlates weakly with serum CK levels, irrespective of rest interval length between sets.     

Competition and diversity in higher education: an empirical approach to specialization patterns of Portuguese institutions

The expansion of higher education systems has often been associated with the need for increasing diversification, namely at the program level, based on the pressures to adapt more general programmes to a more diverse student population and multiple regional, social, and economic needs. This paper explores empirically the question of programme diversity by drawing on the Portuguese higher education’ experience, which presented massive expansion during the last decades and significant institutional competition in recent years. The study provides a longitudinal approach and analyzes in detail the evolution of diversification and specialization of the public and private sectors, as well as the university and polytechnic subsectors. The analysis aims at helping to illustrate the relevance of analysing diversity from an empirical point of view and its contribution to our understanding of the complex relationships between competition and diversity in contemporary higher education.     

Teaching for quality learning in chemistry

In Portugal, the number of students in higher education increased from 80,000 in 1975 to 381,000 in 2000 (a change from 11% to 53% in the age group 18–22), meaning a major change in the diversity of student population with consequences well known and studied in other countries. The teaching of chemistry at the University of Aveiro, for the first‐year students of science and engineering, has been subjected to continuous attention to implement quality and student‐centred approaches. The work devoted to excellence and deep learning by several authors has been carefully followed and considered. This communication reports research work on chemistry teaching, associated with those developments for first‐year students. The work included the design of strategies and the adoption of teaching and learning activities exploring ways to stimulate active learning by improving the quality of classroom interactions. In addition to regular lectures, large classes' teaching based on student‐generated questions was explored. In order to improve students' motivation and stimulate their curiosity, conference‐lectures were adopted to deal with selected topics of wide scientific, technological and social interest. Quantitative analysis and discussion of selected case studies, together with the organization of laboratory classes based on selected enquiry‐based experiments, planned and executed by students, stimulated deep learning processes. A sample of 32 students was followed in the academic year of 2000/01 and the results obtained are here discussed in comparison with those of a sample of 100 students followed in 2001/02. Particular attention was paid to the quality of classroom interactions, the use of questions by students and their views about the course design.     

The transformative power of Chicana/o Studies: social justice and education

This essay responds to Professor Aguirre’s article in this issue that explores through personal narrative the trials and tribulations of being a faculty member with an expertise in Chicana/o Studies. The author joins his exploration by introducing the structural disadvantages that Chicana/o Studies suffers as a field. She then expounds on what we have gained by developing a new field with an explicitly political focus that includes putting student interests at the center of its development while fighting for economic and social justice as an integral part of its intellectual agenda. Her conclusion explores the challenges that the field of Chicana/o Studies faces as we confront changing demographic and societal conditions.
