An integrated safety monitor to assist in the governance on policy goals: theory, practice and lessons learned
This article provides a case description of the development of an integrated safety monitor for the governance on policy goals. The governance on these safety goals took place in cooperation between eight municipalities and Police, Justice, Fireworks, Health Care providers for addiction or domestic violence and partners in incident and crisis management. Two problems were adressed. The first problem is that the evidence on process and results of monitoring from data to interpretation and policy choices in cooperation with different safety partners, is scarce. The second problem is that monitoring of a wide range of indicators on integrated safety is also scarce. In our case, the gathering of data and the interpretation of these data together with all the partners formed a cyclical process. This corresponds with the theory of governance developed by Ansell and Gash in a meta-analysis in 2008. The starting conditions were made clear. The design of the monitoring process was translated into themes of working sessions with a group of policy advisors, giving them a structure for the governance on the policy goals. This group developed a layered set of indicators. These set of indicators was broken down in the four policy goals as well as in different steps in the safety chain. Indicators from different registrations of the safety partners were combined with indicators about the perception of safety measured by a representative sample of the residents. The layered set of indicators was supportive in the discussion about a well balanced monitoring on prevention, signals, interventions and effect. The data were interpreted together with the safety partners. This was helpful in creating a joint perspective on safety problems and in the discussion about meaningful policy actions. The challenge now is to persevere in the cyclical process from data to interpretation and shared understanding about policy goals.
Una reflexión curricular sobre la enseñanza de la estructura de la sustancia en la formación de profesores de química
Authors: Ferro V. R. , González Jonte R. H. , Cruz Z. 
Published: June 2021

In this article we reconsider the manner of teaching the concept of structure of substance in order to improve the teaching performance of chemistry teachers. In order to achieve this goal we modify the habitual, static presentation of substance to relate it to thermodynamic and kinetic aspects. In this way we facilitate a better understanding of the chemical change.
Geología, ciencias de la tierra, ciencias de la naturaleza: paisaje de un aprendizaje global
Authors: Anguita G. 
Published: June 2021

Notwithstanding its profound contributions to modern Science, Geology importance in Science Education has been (and still is) continuously dwindling. This situation is universal and has historic roots. At the same time, a reintegration of Geology with other sciences has been taking place, resulting in the Earth Sciences. The Earth Sciences concept is better adapted than Geology to new conceptual advances such as Systems Theory, Catastrophe Theory, or Chaos Physics. Nevertheless, caution is of essence when adapting those physico-mathematical theories to a Science whose methods are not mainly experimental but descriptive and historie. One of the present lines of advance in Earth Science Education is based on courses in which biologists and geologists together analyse Earth and Life systems. Viewing towards a farther horizon, we can find courses on Science integrating Biology, Chemistry, Geology and Physics concepts included in the new school curriculum. Although highly commendable in theory, the scheme is probably deemed to result in no real progress towards integrating Science, since it is not accompanied by deep changes in University curricula.
Epistemología, caos y enseñanza de las ciencias
Authors: Luffiego García Máximo , Bastida M. F. , Ramos F. , Soto J. 
Published: June 2021

In this article it is maintained that modern science is going through a critical period where its epistemological assumptions and the use of a parcelling and reductionist methodology are questioned. This will surely have important implications in the teaching of the sciences, perhaps because the world today demands above all an epistemological change in the people who, within a few years, will occuppy the posts in the production and reproduction of scientific and technical knowledge

Contribución de la historia y de la filosofía de las ciencias al desarrollo de un modelo de enseñanza/aprendizaje como investigación
Authors: Gil Pérez D. 
Published: June 2021

After the fiasco of the «Iearning by discover y» orientation and the serious limitations of the «reception learning» paradigm, a new consensus is emerging on the nature of mathematics and science learning as a construction of knowledge. These constructivist approaches have taken explicitly into account contemporary views in philosophy of science as an epistemological base for a conception of learning as a conceptual change. Teaching strategies oriented to produce conceptual changes have been developed with promising results, but serious difficulties have also appeared. Our contribution will try to show that those difficulties are due to a still insufficient consideration of the nature of science in the teaching strategies. Consequently, we shall propose some modifications of these strategies, taking more carefully into account the relationship between the nature of science and the nature of learning.
Aprendizaje por descubrimiento: principios y aplicaciones inadecuadas
Authors: Barrón Ruiz A. 
Published: June 2021

This article deals with a critical analysis of the practical applications of discovery learning. To this end, the principles on which we have reconstructed that theory of learning are used, according to a constructivist foundation of cognitive activity as a conjectural activity, mediated by sociocultural orientations. This article is based on previous research by the author (Barrón 1989, 1991a, 199 I b). After defining and establishing the theoretical principles, the inadequate practical applications of discovery learning are examined, derived, in some cases, from an empiricist concept of discovery, and in others, from a «scientific reductionism», «individualist», or «rnechanistic» concepts of learning by discovery.

Results of the evaluation of an instructional system which take account of how past experiences and knowledge influence perception, comunication and learning are presented. Experimental activities, problem solving, and discussion period for contrasting previous and new learning have been emphasized in the instructional design. Instructional strategies such as conceptual maps, Gowin's heuristic V and problem solving have been used. The instructional system was evaluated with a sample of 76 secondary school. The selection was based on previous knowledge of optics and the determination of misconceptions in cognitive structure of the same population. Results show relevant differences in tests between controlled and experimental groups.

Análisis de contenidos en óptica geométrica
Authors: Perales Palacios F. Javier 
Published: June 2021

This work reports on the findings of a content analysis in geometric optics. Such analysis has been carried out through two dimensions of the scientific content structure, the substantive and curricular ones. For that purpose, a consensual criterium out of nineteen textbooks of physics including the topic mentioned has been adopted. The first type of analysis leds to identify the «key» concepts and their relations in a hierarchized conceptual map. On the other hand, the curricular analysis resulted in a proposal of sequentiation for the implied contents. At the end, didactic consequences of the procedure described are discussed.

La realimentación en la evaluación en un curso de laboratorio de Física
Authors: Colombo de Cudmani L. , Pesa de Danón M. , Salinas de Sandoval J. 
Published: June 2021

Methods of continous evaluation with feedback as well as those of discontinuous evaluation without it are discussed. Even though at first sight the former offered advantages upon the latter, and considering their costs in terms of time and effort when working with large groups, it was thought advisable to make a measurement leading to some objective judgement. An experience with students attending a Physics Laboratory Course, 2nd. year Engeneering, was carried out, taking two sample groups and two reference groups, each one constituted by 50 students. After planning and carrying out the experience, results are analized and conclusions drawn which appear to show that the disadvantages implied by continuous evaluation with feedback are largely compensated by the results obtained.

Como fomentar los principios de actividad y creatividad al aplicar el método científico en la Escuela. Un ejemplo para la formación de maestros
Authors: Lillo Beviá José 
Published: June 2021

The results of an experiment about the permeability of soils is commented and proposed to three groups of students of the Teacher Training School in Pontevedra. A guide for the activity is not given, but with some indications. The students design the experiment and its parts, criticize their own activity and correct their mistakes. It is verified that the richess of ideas given by the students exceeds the previsions which an ordinary teacher would do in designing the guide of a given experiment. The student does not only verify the experiment guide, but he is the designer and the critic of the investigating process. The results obtained encourage us to practise an active, creative and inexpensive methodology in the training of future teachers.

“Its Hand around My Throat”. The Social Rendering of Borrelia
Authors: Soncco Ritti 
Published: June 2021

This paper builds on biomedical and anthropological discourses of microbial agency to explore the important opportunities this discourse offers medicine, politics, anthropology, and patients. “Borrelia burgdorferi”, often termed “the Great Imitator”, is an ideal candidate for this discussion as it reveals how difficult it is to speak about Lyme disease without engaging with microbial agency. Based on 12-months research with Lyme disease patients and clinicians in Scotland, this paper offers a social rendering of the bacteria that reveals epistemologies of illness not available in medical accounts: the impact of social and psychological symptoms such as body dysmorphia, depression, shame, post-traumatic stress disorder, and suicide-related deaths on patients’ illness narratives. Divorcing agency from the bacteria silences these important patient narratives with the consequence of a limited medical and social understanding of the signification of Lyme disease and the holistic methods needed for treatment. This paper furthermore argues that the inclusion of patient worldings of Borrelia acting in the medical renderings offers a democratic determination of what the illness is. Finally, building on Giraldo Herrera and Cadena, I argue for a decolonization of Borrelia, exploring how the pluriverse both takes the epistemologies of patients seriously and reveals medical equivocation.
In the Images of Development
Authors: Banerjee Tridib 
Published: June 2021

The urban legacy of the Global South since the colonial era and how sustainable development and environmental and social justice can be achieved.
Remarkably little of the expansive literature on development and globalization considers actual urban form and the physical design of cities as outcomes of these phenomena. The development that has shaped historic transformations in urban form and urbanism—and the consequent human experiences—remains largely unexplored. In this book, Tridib Banerjee fills this void by linking the idea of development with those of urbanism, urban form, and urban design, focusing primarily on the contemporary cities in the developing world—the Global South—and their intrinsic prospects in city design. Further, he examines the endogenous possibilities for the future design of these cities that may address growing inequality and the environmental crisis.
Banerjee deftly traces the urban legacy of the Global South from the beginning of the colonial era, closely examining the economic, political, and ideological forces that influenced colonial and postcolonial development, drawing from relevant experiences of different cities in the developing world and discussing the arguments for the historic parity of these cities with their Western counterparts. Finally, Banerjee considers essential notions of future city design that are grounded in the critical challenges of sustainable development, equity, environmental and social justice, and diversity, and how such outcomes can be achieved. This book serves as the opening of a long overdue conversation among design, development, and planning scholars and practitioners, and those interested in the urban development of the Global South.
Effects of Prilled Urea, Urea Briquettes and NPK Briquettes on the Growth, Yield and Nitrogen use Efficiency of BRRI Dhan48

Nitrogen is one of the most deficient plant nutrients in Bangladesh soils. The use nitrogenous fertilizer especially urea is a commonly used fertilizer for rice production but its efficiency very low about 30-40% under traditional broadcast method A field experiment was carried out in the Soil Science Field Laboratory of Bangladesh Agricultural University, Mymensingh during Aus rice growing season of 2014 to investigate the effects of prilled urea, urea briquettes and NPK briquettes on the growth, yield, and nitrogen use efficiency of BRRI dhan48. There were six treatments as T1 [check (N0P16K42], T2 [Urea briquette (one-3.4 g) (N52P16K42)], T3 (Urea briquette (one-2.7 g (N78P16K42)], T4 [NPK briquette (one-3.4g)(N51P13K32], T5 [Prilled urea (N78P16K42)] and T6 [NPK briquettes(two-2.4 g briquettes (N78P15K42)]. The experiment was laid out in a Randomized Complete Block Design (RCBD) with six treatments and four replications. Prilled urea was applied in two equal splits application; at 8 days after transplanting (DAT) and the second dose after 38 DAT, while for urea briquettes and NPK briquettes were deep placed (8-10 cm depth) at 8 DAT between four hills at alternate rows. Water samples were collected for every 7 consecutive days and analyzed for NH4-N. The results showed that the NH4-N concentration in floodwater reached to maximum on day 2 in PU treated plots and then decreased with time, while the urea briquettes and NPK briquettes treated plots slowly produced NH4-N over the growth period. The highest grain yield of 4.75 t ha-1 (69% over control) was obtained in the treatment T3 [Urea briquette (one-2.7g) (N78P16K42)]. The treatment T3 also produced the highest straw yield of 5.49 t ha-1. The maximum apparent N recovery and the maximum N use efficiency were found in the treatment T4 [NPK briquette (one-3.4g) (N51P13K32)]. It appeared that the deep placement of urea briquettes and NPK briquettes reduced N-losses and enhanced the recovery of applied N as well as N use efficiency in comparison with PU application.
Stress-Strength Reliability Quantification using M-Transformed Exponential Distributions
Authors: Khan Adil H. , Jan T. R. 
Published: June 2021

The term “Stress-Strength reliability” means , where a system or an equipment with random strength X is subjected to random stress Y in a way that system breaks down, if the stress surpasses the strength. In this paper, a system is considered with standby redundancy, and it is presumed that the distinct components in the system for both stress and strength variables are independent and have different probability distributions viz. M- Transformed Exponential, Exponential, Gamma and Lindley. The expressions for the marginal reliabilities etc. based on its stress-strength models are obtained.
